The book “Fantasy of Artificial Intelligence. However, with AI’s capabilities are fantasies and fears for the future of humanity. The real danger is not that computers are smarter than humans, but that people think computers are smarter than they are, and therefore trust the computers to make important decisions for them, because computers are perfect. They can all make serious mistakes, when the way they process data is not the way humans think. In order to explain thoroughly, debunk misunderstandings, and dispel illusions, author Gary Smith – Professor of Pomona College, USA wrote the book “Fantasy about artificial intelligence”. The book is divided into 12 chapters, including many real-life examples from history such as the 2008 US presidential election, IBM’s AI Watson and many other famous artificial intelligence projects with the aim of clarifying how intelligence works. Artificial intelligence processes information, gives the final result and shows the difference between AI (Artificial Intelligence) and the human brain, thereby showing readers the risks of over-trusting. computer results. In the first 4 chapters, the author has taken a lot of real-life examples to explain in an easy way how artificial intelligence works and how they give the end result. The author claims that robots have surpassed humans in repetitive monotonous tasks, they have better memory, perform more accurate calculations and are tireless. But artificial intelligence is not programmed to simulate the human brain, and artificial intelligence cannot think, reason, and make analogies. Since then, the author asserts that up to now computers with comprehensive intelligence enough to compete with humans have not yet existed. In the next two chapters, by referring to “Data Mining”, it is proven fact that Data mining although there will sometimes be a real knowledge discovery, given the number of explanatory variables The larger the consideration, the more likely it is that a relationship discovered is just a coincidence, of a temporary nature. In the remaining chapters of the book, the author has introduced many computational models in many fields such as finance, politics, economics… to prove that statistical evidence is not enough to distinguish between knowledge real and fake. The computer cannot accurately judge whether the correlation is random or truly significant. That work is only for the human mind. In conclusion, human intelligence works differently from artificial intelligence, so it cannot be said that artificial intelligence is intelligent. Robots excel in memory, accuracy, and endurance, but they still have many shortcomings: they can’t think, can’t make analogies, and can’t distinguish between good-bad, meaningless-meaning data. Humans need computers to process large amounts of information, but also need human intelligence to make final judgments about the results returned by computers. About the author, Gary Smith has been involved in many research projects that highlight the questionable use of data in statistical analysis. He has published 8 textbooks, 7 business books, nearly 100 academic articles and 7 software programs in economics, finance and statistics. In addition to teaching at Pomona College, he is also an economic analyst and consultant. His other well-known books such as “Standard deviation: Flawed assumptions” and “Tortured Data” also warn about the dangers of confusing correlations. and causality in statistical analysis.

Here are five real people who suddenly became geniuses after a sudden accident and are proof of savant syndrome. People who suddenly become geniuses after a sudden accident Jason Padgett – math talent Although many people are gifted with music or the arts, Jason Padgett’s talent is in math. Jason dropped out of school in the past, worked in his father’s furniture store and often indulged in parties. At the age of 31, he became a math and physics genius overnight after being hit in the head during a petty theft. Diagnosed with savant syndrome – a brain injury that turns ordinary people into experts in math, art or music. Jason has the ability to draw fractal by hand. Jason is one of the few people in the world who can draw a fractal by hand. These images are repeated many times and can take weeks if not months to complete. After his injury, Padgett drew complex geometric shapes, but he was not properly trained to understand the equations they represented. One day a physicist discovered he was drawing drawings. in a shopping mall, and advised him to pursue math training. Since then, Padgett has taken the path of mathematics. Orlando Serrell- super memory At the age of 10, Orlando Serrell was born in 1968, from Virginia, was hit by a baseball and had to quickly end the game. “I didn’t tell my parents,” he said, “so I didn’t go to the hospital after the accident.” However, after that accident, Orlando suffered from headaches for a year. But when the pain finally subsided, Orlando realized he could recall the day of the week for any given day and never made a mistake. He can do amazing calendar calculations – from knowing how many days are between certain dates or how many times March 12 fell on a Thursday. Also, sometimes Orlando can remember every detail exactly. happened during the day like the weather that day and what he did that day. Apparently, a mild concussion gave Orlando Serrell special abilities. Daniel Tammett – math genius Daniel Tammett became obsessed with numbers after he suffered a seizure at the age of three. During his years in school, Daniel has won many awards but no one has recognized his extraordinary ability. It was not until the age of 25 that Daniel was diagnosed with high-functioning autistic savant syndrome, which allowed him to calculate with astonishing accuracy. Daniel counted the number of digits 22,514 decimal places in 5 hours and 9 minutes. Daniel also speaks 10 languages, including Icelandic, which he learned a week after a challenge for a TV show. Ben McMahon – unexpected language ability When Ben McMahon went into a coma after a car crash, his parents feared that he would never wake up. But a week later, the Australian student woke up and suddenly spoke Mandarin (a language of Chinese). Ben used to learn basic languages ​​in school and failed. “When I woke up and saw a Chinese nurse, I thought I was in China,” he said. It was like a dream. I started speaking Chinese as soon as I woke up.” Ben later also recalled English but his Chinese remained and Ben used this unexpected talent to earn a living as a Chinese-speaking tour guide in Austria and on Oh My God – a show. TV program in Chinese to help Chinese settlers in Australia. Lachlan Connors – musical prodigy Lachlan Connors, from Denver, Colorado (USA) has such a poor sense of melody that he cannot play children’s songs on the piano, much to his mother’s disappointment. However, Lachlan Connors has twice suffered serious concussions when he was involved in an accident during sports matches. As a result, Lachlan Connors suffered from seizures and hallucinations, forcing him to give up his interest in sports. But the 17-year-old young man’s injury at the time had a positive side effect. Lachlan acquired the skill of learning to play an instrument with ease. Experts believe his epileptic seizures may resemble those of composer Frederic Chopin. From someone with no musical talent, Lachlan now plays 13 instruments including piano, guitar, mandolin, ukelele and harmonica,… Derek Amato – musical ability When Derek Amato was diving into a friend’s pool in October 2006, he accidentally injured himself by hitting his head on the pool floor. Derek was later diagnosed with a severe concussion, hearing loss and headaches. Later, Derek became homeless after a failed business deal in 2002. But a few weeks later, Derek saw a piano at his friend’s house and was “pulled” to play it. Derek explained that he suddenly knew how to play when he saw the black and white squares move from left to right causing his fingers to move. Derek can now play eight instruments and has released two albums. What is savant syndrome? Savant syndrome, also known as genius syndrome, occurs when the brain reacts to trauma. According to Dr. Mara Klemich, a neuropsychologist who has studied traumatic brain injury and in the fields of neuropsychology, this syndrome refers to new skills or abilities that suddenly appear in a person. someone they didn’t have before. These new abilities occur after brain injury, stroke, or other central nervous system problems, and even dementia. Although rare, Dr. Klemich has seen two patients develop develop extraordinary skills, such as drawing and painting after an accident. In addition to these two skills, Dr Klemich said there are people who develop other intelligent skills including calculating calendar dates, math, art and music. Some people think that people with this syndrome will suddenly become brilliant at all areas. However, Dr Klemich said most cases only show specific skills in one of those areas. The exact cause of this syndrome is still unknown. (Illustration) The causes of savant syndrome are not well understood. Savant syndrome can be caused by neurodevelopmental disorders such as autism spectrum disorder or it can also be caused by brain injury. Some common causes of Savant syndrome: • Genetics: Most people with Savant syndrome are hereditary. • Trauma: Degenerative diseases or head trauma can also lead to this condition. Some experts believe that complications a baby has at birth will lead to Savant syndrome. • Hormones: The male hormone testosterone is thought to speed the development of infantile syndrome. This hormone also inhibits the production of the hormone oxytocin, a hormone that helps you adapt to society. Furthermore, it is thought that mutant neurons are also responsible for this syndrome. However, the actual cause of Savant syndrome remains unclear. Sometimes, this syndrome can be detected when the patient is young, but in other cases, the disease is discovered until adulthood.

Illustration. Every day, you should drink 2-3 cups of green tea, this antioxidant-rich drink after being absorbed by the body not only minimizes the harmful effects of radiation from the computer, but the vitamin A in the tea leaves also contains vitamin A. can protect and enhance your eyesight. Daily should eat a moderate amount of carrots, bean sprouts, tomatoes. Fruit juice has a sour taste and juice from green vegetables is a very good body cleanser, if possible, should drink it regularly. Wash your face The radiation emitted from the computer is considered a catalyst that causes the skin to absorb a lot of dirt in the air, which in the long run will lead to the appearance of wrinkles, freckles, acne… promptly wash your face with clean water, it will reduce over 70% of radiation. It is best to wash your face with warm water mixed with a few drops of lemon juice, followed by a gentle massage to remove dirt, then apply lotion to restore the skin. Drink a lot of water This is a simple but highly effective skin care secret. Most of the words shared about beautiful skin care by beauty bloggers, famous stars, beauty queens, etc. refer to drinking lots of water. You may not know, radiation from computers is one of the causes of dry skin. When the skin lacks moisture, the sebaceous glands are forced to work continuously to compensate. This causes your face to have an excess of oil, causing an unsightly shine. In addition, excess oil clogs pores, making the skin prone to acne. Therefore, drinking water is very necessary to compensate for the amount of moisture lost during work. However, how much water is enough for the body is also quite important. Drinking too much water can easily lead to excess water in the body, causing edema. Better yet, you should drink enough from 2-2.5 liters of water every day to keep your skin smooth. Relax your skin Busy work makes her always focus on the computer constantly, so she often forgets to let her skin rest. Just like the brain, the skin also needs rest after a long period of activity. After every 1-2 hours of work, stand up, breathe and close your eyes gently to relax the whole body. On the other hand, you can go get drinking water to moisturize the skin and help the eyes and brain to be released. Apply this habit regularly, you will find your mind at ease and work more efficiently.

Face bowing gesture This is a move you can come across in any yoga sequence because it is so familiar. The pose helps to stretch, strengthen the muscles and balance the spine. It also makes you more mentally alert. The reverse flow of energy generated when doing this movement is very good for breathing, reducing stress and anxiety. Close-up posture You can use a small pillow, thin blanket, or rug under your buttocks. Inhale deeply, exhale gently while pulling your body close to your knees. Remember not to try to pull your body down with your head, but use your back. No need to push yourself too deep if you are not resilient enough. Hold this position for about 3 minutes and then slowly raise your back again. The movement will relieve tendon pain in the elbow, stretch the spine, relieve back pain. It’s a bit challenging, but it will also make you feel more comfortable with regular practice. Baby Pose Experts have confirmed that the therapeutic benefits of this move are endless. It lightens the mind, relaxes the hip area, stretches the ankle joints. For those who have practiced yoga for a long time, this move helps them find the right feeling about their body and person. Hold this pose until your body feels “enough”. Meditate Sit cross-legged. Choose the most comfortable way to cross your legs, just keep your back straight. Relax your hands comfortably, close your eyes and temporarily distance yourself from the outside world for a few minutes. Just like that, just like the name of the move. Put your feet on the wall This movement helps the body eliminate toxins and release bad energy. Just by changing the flow of blood, you can create a new source of energy, helping to relieve ailments like headaches, insomnia and anxiety, even mild depression. Lying meditation To finish the yoga sequence, lie comfortably on a mat or a thin blanket. At that time, your body is having the greatest contact with the ground. Let your limbs spread freely, breathe rhythmically and steadily, bring your imagination into harmony with nature, clouds, flowers and grass, and gently smile and relax for 2 minutes. The only thing you should pay attention to is not to let yourself fall asleep. Posts: Beautiful Lifestyle

Create a clean path from the speaker to the listener’s ear The perception of stereo sound depends on subtlety and in particular on the presence of live sound as well as the immediate feedback that follows. Incoming sounds play a general role in what you’re hearing, but they’re not as important in stereo as the “first-in” effect (the latter is considered unimportant by the ear/brain’s decision). spatial and positional information). Now do you understand what we mean by “clean road”? You don’t need anything on the floor or anything else close to the path from the speakers to where you sit. The floor and ceiling of the listening room should be flat and smooth because high frequency reflections will be minimized. If the ceiling is not very high, it is better if it is made of a soft and smooth object. The problem here is that rough materials, such as appliances and furniture, will cause the sound to be distributed unevenly. This is one reason why the stereo effect is blurred and the ideal performance cannot be obtained. A friend in the test room asked me to close my eyes to test the change of stereo sound when there is an obstacle in front. When the music plays, I feel the change quite clearly, the stereo comes out in parts, becomes distracting and the sense of space is seriously affected. Then my friend told me to open my eyes. What surprised me the most was that he just silently placed the CD cases on the floor symmetrically between the speakers and a few in front of us. This is obviously not a huge physical change, but it does sabotage stereo performance a lot. So what if you put a coffee table or put a few remotes on it symmetrically with two speakers and in front of a music chair? Maybe it will be convenient for you to enjoy the melodious music while sipping a cup of coffee, but you will certainly not be able to fully feel the stereo performance. Get rid of objects next to you, use a chair with a low back Although using a chair with a low backrest, the arrangement of the chair as shown in the picture makes it impossible for both listeners to experience the stereo effect. Hard objects near your ears along a straight line are seen to greatly affect when you listen to music. It’s best to sit in a chair with a very low back, as that will put nothing near your ears. If your back doesn’t adapt to this, you should at least use a chair that doesn’t go over your head and make sure it’s soft. Hard leather sofas become weak points because they reflect high frequencies. If you are sitting alone, cover the area behind and near your head with a cloth curtain. Because otherwise, a lot of high frequencies will be scattered before reaching you, or in other words, the back wall of the listening room should design sound-absorbing materials or accessories. But using a low chair is still best. Try it! You will be surprised how much better your system will sound. Symmetry rule Stereo sound is based on symmetry between two channels. For the latter, where people are exposed to large amounts of treble diffusivity, the role of symmetry is diminished. But for anything that comes first with the sound of low frequencies, the role of symmetry is indispensable. In the old days, when many audio players didn’t understand how stereo really worked, and especially didn’t fully appreciate the importance of the intrinsic tonal time difference, many would try to make adjustments. difference between the two channels by electronic means, i.e. adjust the equalizer and use a separate equalizer for the channels. The result was, of course, a disaster, because analog equalizers and EQs couldn’t deal with asymmetric timing effectively. When that happens, the actual digital signal processing (DSP) may be full of detail, but the problem lies in the accuracy. So it’s better to make the whole system as symmetrical as possible from the start. As always, the tuning DSP room works best when there is a lower frequency response peak and sag and is less demanding for correction (the one exception is the very wide, very useful bass correction. useful in practice). Part of the task of symmetry is on you, which is to keep the two speakers evenly spaced. In general, everyone does this, but they don’t do it fully and carefully. Let’s take a quick look at the numbers. People can hear a time difference between the two ears of about 1/100,000 of a second. But let’s stay conservative and give it only 1/50,000th of a second. How far will the sound go in 1/50,000th of a second? Well, a millisecond (1/1000 of a second) is about a footstep. So 1/50,000 is about 12/50,000 feet, which is about a quarter of an inch. So if you want stereo speakers, you need to get them within a quarter of an inch. Time is a measure! Mark the spot and keep it there. Sit near your speakers loa There will always be some sound coming soon that you really don’t expect. So try to make them symmetric and have smaller amplitudes, but there are bound to be some limits. The way to minimize their effects is to make the live sound appear as early as possible. Sitting close to the speaker is how you do this. Of course, you also can’t sit too close, because most speakers depend on a certain distance for the accuracy of the drivers. And to some extent, you need some distance to avoid hearing the microscopic vibrations because that can make the speaker more visible than the music source. But you’ll get the best stereo sound if you sit reasonably close to the points. Many people sit too far and to the far end of the room due to the fact that the music room is too long. Sitting closer to the speaker changes the direct sound reflection ratio. You should also sit away from the wall behind your back, and the speakers should also be away from the wall behind them (unless they are designed to be wall-mounted), because positioning the speakers and listeners too close to the wall will cause discomfort. benefit the sound of a stereo system. Need a soft room Many recordings (CDs or LPs) are made with the expectation that some room sound will be added as the music plays. A few other recordings were made with the expectation that they would not be echoes when heard. But all those effects don’t stand a chance if your listening room is too small. In my opinion, the best stereo sound should be presented in an RFZ (no-reflection room) room. In such a room, early incoming direct sound will be in moderation, and sound reflection will soon be absorbed. After you hear the live sound, the listening room will appear to be assisted by sound diffusion, where discrete sound reflections are not evidence, or the sound will arrive too late after the initial sound. arrived. As a result, live sound is heard more clearly, without being confused. While building an actual RFZ room is quite a challenge, you can handle it well by making a “soft” listening room, which will especially help the treble get the most out of it. In addition, a soft acoustic environment will also result in more harmonious notes. If your music room has a large picture, use fabric drapes to cover it while listening to music. In particular, the wall of the music room made of glass would be a disaster. A few years ago, a friend brought to my apartment a system to edit rooms. Then this apartment had a spectacular view, located on a high ground and had a long wall of nothing but glass and steel support. But when it comes to music, it’s clear this room can’t get the most out of it unless I add some curtains. Sit still and close your eyes Part of that symmetry is placing the music chair in the right position. Unless you move the seat straight forward or backward, you will end up in an asymmetrical position! But there is another way of sitting that is really subtle and more important than the effect. This is a complex topic so I can only give an overview. As the brain builds perception from raw data during processing, what we “see” or “hear” is not the same as light in our eyes or sound in our ears. Because it’s just a mental construct. This particular mental construct often includes the following surprising things: it will use many signals, but if one signal is lost, the brain will recognize it as lacking and simply reprogram itself to use other signals. This may sound crazy, but there’s a simple visual experiment you can illustrate with that principle. Look at a photograph with a lot of three-dimensional (3D) material in it or at a painting with strong perspective, then you will get some impression of a three-dimensional image. But if you look at them with one eye closed and the other through a short tube that blocks the background and only allows you to see the picture, there is a surprising increase in the perception of three-dimensional images. If you’ve never tried this, you’ll have a hard time believing that your eyes can see the background around the picture of the picture (the way you usually look at a picture), and the brain will pick up some signal about the picture. that three-dimensional perspective. But the brain will also receive information that the surface of the painted or printed picture is in fact only two-dimensional. Binocular vision shows a fatter picture, and the background shows it too. So the brain is getting conflicting signals, which means it allows you to see some of the three-dimensional image, but not all of it. When you look with one eye and don’t see the background, the signal to that fatter image is blocked. Going back to the world of sound, one of the ways the brain detects the position of an object, the shape of the hearing room, of space, or in general auditory terms, is to slightly move the head and Notice the changes in the sound. People will have the feeling that they suddenly “sink into” the space of stereo sound. There are some people who choose to sit absolutely still. This will put the listener in a quiet state, and obviously very suitable for listening to music. And, to my ears, the stereo got better. Finally, closing your eyes also eliminates cues that a person can’t hear in a concert hall or a stadium, but can hear from the speakers in your listening room. In short, sit with your eyes closed, with your head completely still, in a chair near the speakers in a “soft” room and in the correct symmetrical position with no obstructions in the line. between you and the speaker. If you do all that, I guarantee your stereo system can perform at its best. Hope you find the best stereo sound!

Fantasy of artificial intelligence has just been released in Vietnam. (Source: Nha Nam) The book also gives the final result and points out the difference between AI (Artificial Intelligence) and the human brain, thereby showing readers the risks of over-reliance on machine results. count.

The computer cannot accurately judge whether the correlation is random or truly significant. That work is only for the human mind. Computers smarter than humans? It can be said that artificial intelligence (AI) is one of the most interested keywords. Now, thanks to AI, we can do things that were never possible before and never thought we could do. However, with AI’s undisputed capabilities are fantasies and fears for the future of humanity. The real danger is not that the computer is smarter than us, but that we think the computer is smarter than us and therefore trust the computer to make important decisions for us.

Bad dreams protect us in real life Most of us have had bad dreams at some point in our lives, although they seem scary, there are actually good sides to bad dreams. Researchers claim that feeling fear in dreams can actually help you better cope with real-life fears. Bad dreams enhance the brain’s ability to react to real-life dangers and frightening experiences. However, in terrifying and traumatic dreams, those benefits are lost and they can actually cause ill effects that continue after awakening. Illustration. Most muscles are paralyzed during REM sleep During deep REM sleep, the stage in which we sleep where most dreams occur, our eyes continue to move but the muscles are paralyzed. According to a study, a set of specialized cells in the brain called motor neurons prevent muscles from moving when we sleep to prevent potential injury. Illustration. Dreams enhance creativity and problem solving Many people have had incredible breakthroughs in their dreams. Whether it is a scientific idea, art, music, novel or film, reality shows that dreams can create real gems and there is a perfectly valid reason backed by science. household. When we dream, our brain is in a different neurophysiological state, allowing it to become more adept at solving problems and finding solutions to things that baffle our minds. . In this state, we experience higher brain activity, which makes the brain more capable of coming up with creative solutions and problem solving. People forget 95% of their dreams We all know how difficult it can be to recall dreams after waking up, not to mention recalling older dreams from weeks, months, or years ago. In fact, we forget up to 95% of our dreams. This is because the changes in the brain that occur when we sleep do not support the information processing needed to store and form memories. Brain scans of sleeping people show that the region that plays a key role in memory formation found in the frontal lobes is inactive during REM sleep. Illustration. Not all dreams have color Although it may sound surprising, not everyone is able to see colors in their dreams. The phenomenon dates back to the 1940s when many people reported having dreamed of black and white. Today, studies suggest that this has to do with the fact that at the time people were exposed to black and white media because color TV had not been invented. To support this theory, a study was conducted on 2 different age groups with different media exposure experiences. People with more exposure to black and white media had more gray dreams than those with more experience with color media. Illustration. Blind people can also have visual dreams People who are born blind can have visual experiences in dreams because they have the same electrical activity in their brains as people with normal vision. However, even though they have visual sensations in their dreams, they cannot describe the experience and conceptualize the feeling as if they had never experienced the sight in their life. Dreams are motivated by memory, so people who lose their vision later in life can experience visual dreams thanks to brain circuits that were formed before they went blind. Illustration. You can’t read in your dreams When we are reading, this is when the right part of our brain is most activated and this is exactly the part of the brain that cannot be reached while dreaming. In fact, when we dream, the entire brain region responsible for language, reading, writing and speaking becomes less active. However, there is an exception to this rule and some people can read it in their dreams. However, this only applies to a small number of people – usually those who think about language and write the most like writers and poets. We only dream of faces we have seen in real life Whether you really miss them or not, you can only dream of faces you’ve seen in the past. Our dreams are drawn from real experiences, so the faces you see in your dreams are the result of your interpretation of actual experiences. Illustration. Dreaming is a real phenomenon We all catch ourselves drifting away with our minds and not being fully in the present moment, almost everyone has experienced this. However, daydreaming, in the real world sense, can happen to some people who are capable of daydreaming so vividly that they almost experience their presence in a different environment. Illustration. Being able to control your dreams By experiencing lucid dreams, you can become aware that you are literally dreaming and thus take control of your dreams. This type of dream is related to a higher awareness of your mental state, and people who have experienced lucid dreams claim that they already knew they were dreaming when they woke up.

The human brain is a complex multi-scale structure in which molecules, cells and neurons coexist. It can be modeled as a multi-layered network, called a brain connection pool. Neighboring neurons are connected to form local structures, and different local structures form connections to perform cognitive functions. The human brain is estimated to have about 86 billion neurons. To decipher where consciousness comes from, the researchers used a Swiss supercomputer and used algebraic topology to build a detailed model of the cerebral cortex. Through testing the response of the mathematical model to virtual stimuli and examining the reality of the mouse brain, the researchers were able to determine the details of the neural network on a single neuron. and the entire brain structure. At the same time it was discovered that there are different types of high-powered activity in the brain consisting of a three-dimensional geometric structure – tightly connected clusters of neurons and existing regions. space (cavity) between them. These empty regions appear to be important for brain function. When the researchers applied the stimuli to their virtual brain tissue, they found that the neurons responded to the stimulus in a highly organized manner. This means that as we think about problems, clusters of neurons will gradually coalesce into higher-dimensional structures, forming holes or voids of height. The more neurons in the clusters, the higher the size of the gap, and the highest limit that can be achieved is 11 dimensions. The whole process always follows the order from low to high, the structure will become more and more complicated and eventually collapse. It’s like building a castle on the beach, the castle gets taller and taller and eventually it will collapse on its own. This is exactly like the large-scale filamentous structure of the universe, where galaxies and galaxy clusters form a giant filamentous structure with a giant hole in the middle. In a recent study, it was discovered that our Milky Way galaxy lies within a giant hole one billion light-years across. This study provides new discoveries about how the brain processes information. Scientists speculate that high-dimensional gaps in neuronal structures may be where the brain stores memories, but it’s unclear how these blocks and gaps are formed. How it works, so further studies are needed to determine the connection between the multidimensional structure of neurons and complex consciousness. The interaction between the human brain and the universe is completely different, but there have been many observations and conjectures about the similarity between the neural network and the cosmic network under observation from a microscope and telescope. The researchers quantitatively analyzed the similarity between the two factors based on optical microscopy observations of brain tissue and high-resolution cosmic-matter network imaging, with the help of the method. network analysis. First, there is a huge difference in scale between the brain network and the cosmic network, which is similar only on a specific scale. Brain neural networks are now thought to consist of tens of billions of neurons. The number of galaxies currently observed in the cosmic lattice exceeds 100 billion. In addition, in the neural network of the brain and the network of the universe, only a small amount of matter constitutes the network. There are a large number of holes between giant galaxies, and about 70% of the mass is made up of dark matter. In the human brain too, which is a biological organ, the most important component is water, in the human brain, nerve cells are only 25% and about 75% water. Up to this point, “having water in your head” has a certain scientific basis. In the universe, dense clusters of galaxies predominate, while in the human brain, specifically in neural networks, nerve fibers create uniform small patterns. However, when the researchers increased the magnification of the microscope, they were able to see some similarities to the cosmic web in brain slices.

Nathan Copeland controls a robotic arm using electrodes implanted in his brain. Published in the journal Science, the team say their work demonstrates that adding sensation to the technology significantly improves the function of prostheses for quadriplegics, compared with based solely on visual cues. Nathan Copeland, 34, told AFP: “I am the first person in the world to have a device implanted in the sensory cortex that scientists can use to stimulate my brain directly. And then, I felt like I had a real feel in my flesh and blood hand.” In 2004, Copeland was involved in a car accident that left him with a severe spinal cord injury and quadriplegia. He volunteered for scientific research and six years ago he underwent major surgery to implant tiny electrodes in his brain. Two sets of 88 electrodes the width of a human hair are arranged like tiny combs and penetrate deep into the cortex, which controls motor function. According to Associate Professor Rob Gaunt of the Department of Physical Medicine and Rehabilitation at the University of Pittsburgh, co-leader of the study, fewer than 30 people in the world have received such a transplant. What’s unique about Copeland’s case is that an additional set of electrodes is connected to his dorsal cortex, which receives and processes sensations. The idea of ​​sending haptic feedback to the tactile sensory cortex dates back decades, but doing so in a controlled and understandable way by brain circuitry used to be a major challenge. After Copeland underwent surgery to install the electrodes, the team was truly thrilled. Then came the decisive moment, when they tried sending the first tactile signal. “It felt really fuzzy,” Copeland recalls. He asked them to try again to make sure it was real. Before the interface could work with the robotic arm, the scientists had to perform a series of tests on Copeland. First, they needed to learn which electrodes cause what sensation when activated and which fingers are associated with them in order to set up the robotic hand correctly. They also made him watch a video of the robotic arm moving left or right and recorded the electrodes lighting up when he was asked to “think” it was him controlling it. Copeland sat next to a black metal robotic arm and was asked to pick up a series of small objects such as rocks and spheres and place them in a box – when the tactile sensors were turned on or off. He can complete each task in an average of twice as fast when the sensors are activated, and can even perform more complex tasks like picking up a glass and pouring its contents into a glass. another cup. The team wanted to further refine the prosthetics because they didn’t want to just do science experiments in the lab, but wanted to actually make devices that would be useful to people. Copeland has set up his brain-computer interface at home when the Covid-19 pandemic shut down universities and has used his downtime to learn how to draw on a tablet and even play video games. death. He does this by using his mind to send signals directly to the computer, instead of using his arms to press buttons.

The brain produces enough electricity to light a small light bulb Our brain has about 100 billion cells called neurons. When we move, look, think, dream or laugh, electrical and chemical signals are racing between the billions of neurons on this neural highway. So even though one neuron generates a very small amount of electricity, all of them together can generate enough electricity to light a low-wattage light bulb. Illustration. The sense of smell can take you back in time When we smell something that has a connection with something significant in our past, the first thing we experience is the emotion we had at that moment, then memory often follows. Sometimes we won’t remember the event or situation, but the emotion will be there. This ability actually has a very simple evolutionary explanation. There’s a part of our brain that’s dedicated to detecting chemicals that will signal us if something is approaching, that’s what our sense of smell does. This was very important to our existence in the past. Illustration. We can lift a 60kg person but cannot lift a 60kg rock When we lift “live weight” it is easier because the person can adapt to gravity and distribute their weight in more directions. If this person chooses, they can also put their arms around you, which will make things easy. While lifting an object, such as a rock, the rock cannot choose the distribution of its gravity and weight. Gravity is in the default position and this makes lifting it a lot harder. Illustration. Women’s brains shrink during pregnancy A study confirms that “pregnancy brain” is more than just a phrase used to explain the emotional roller coaster a mother-to-be goes through. The brain actually shrinks during pregnancy, but this is not a negative thing. As it gets smaller, it becomes more effective and the woman prepares for becoming a mother. In fact, the loss of gray matter occurred in the part where it would enhance her understanding of other people’s beliefs, emotions, and nonverbal cues. These changes will boost her ability to bond with her infant and make her aware of threats so she can protect her baby and herself more quickly. To have super strength, the digestive system has to shut down Fatigue, pain, and fear are all things that prevent us from trying to use our strength in our daily lives. We’ve all heard stories about a man lifting a car to save his loved one. That superpower actually comes from adrenaline, but for it to work fully, it needs to shut down the digestive system and immune response. Then the combination of increased energy levels and increased oxygen levels strengthens our muscles beyond normal. Illustration. We can see with our ears Blind people can walk by using canes or clicking on echoes that tell them about their surroundings. But scientists have actually studied the brain of a blind man named Daniel Kish. He described his vision as “something like seeing the world in dim rays”. So when his brain is being studied, the part that controls his visual context actually lights up as he listens to the echoes that help him navigate by clicking. However, when he was listening to other sounds, the area was pretty quiet. This led the scientists to conclude that Daniel was indeed experiencing something like visions. Illustration. Headaches signal bad weather For some people, headaches are not just a signal that we are too tired or overworked, but also a prediction of the weather. In fact, research has confirmed that a number of headaches, ranging from mild to severe, are caused by weather changes. While for some people it can be a rapid increase in temperature or pressure and usually during a storm. During a storm, warm and cold air mix and create a change in air pressure (barometric pressure). In fact, this is how thunderstorms, rain and wind are created. This type of air pressure actually exerts force on a certain area, and in the case of headaches, this “zone” is you. Illustration. The brain has the capacity to store 2.5 petabytes of memory Our brain has about 1 billion neurons. Each cell makes 1,000 connections with other neurons, a trillion connections in total. This gives the brain about 2.5 petabytes – 1 million gigabytes of storage. If we compare it to the length of a digital video, it would be 3 million hours for TV shows, making the video run non-stop for over 300 years. Embryos can heal mother’s wounds There have been many studies involving pregnant women and their unborn babies. The results of these studies have given scientists a new light on the strength of the fetus. During pregnancy, the cells of the embryo move out through the placenta and reside in different parts of the woman’s body. This can affect the mother’s health. In fact, these cells remain inside the body for more than a decade even after the baby is born. They can help the mother heal from injuries during pregnancy. The human ear has the ability to “hear” molecules Illustration. You can take 2 glasses and pour hot water in one and cold water in the other, and when you do this, you can hear the difference. This is because the molecules in cold water have less energy, producing low-frequency tones while hot water has more energy and produces higher-pitched tones, and we can hear and distinguish well between the two.

1. Sprouts Just hearing this unique name, you must be thinking of the stone sprouts in the story of Trang Quynh, right? In fact, the name “germ gravel” comes from the way the dish is processed. The gravel is heated, then used to cook the wild boar meat, which has been thinly sliced ​​and marinated with spices such as pepper, garlic, onion, cilantro, etc. When eaten, people will use it with raw vegetables, dipping in sour chili lime sauce sweet. This dish is considered a famous specialty of Phung Hiep, Hau Giang. Sprout gravel dish. 2. Toss the furnace In fact, this is the Cham pronunciation: tung lamaow. Accordingly, “tung” is the intestine of the “curious” child, which is the cow. Simply put, this is a dish made from beef intestines. This beef sausage dish has long been associated with the Cham people in Chau Doc (An Giang). To make this dish, people use beef intestines to wrap the outside. The inside is beef mixed with minced fat. Just like that, mix all the ingredients with skullcap, spices, star anise and especially fermented cold rice to stuff into beef intestines. Each round, full and finger-sized sausage is tied into a string and dried. After 3 sun exposure, it is enough to drain, hunt meat and can be enjoyed. 3. Humiliation Khau humiliation, also known as lying stitch, is a dish originating from Guangdong, China, introduced to Vietnam through the variation of the Tay, Nung, and Ngai ethnic groups and over time has become a special dish. famous product. It usually appears only on family occasions such as Tet holidays and weddings. The name “humiliation” comes from the Chinese transliteration, where “stew” means “steamed until soft”, and “humiliated” means “meat”. Therefore, if the translation is correct, it can be understood that the meat is steamed or steamed until cooked. 4. Lap lap hotpot “Lap Lap” (also called “Lap Sap”, “Lap Lap” or “Cross”) is a local language, meaning almost the same as “Mixed”. Usually, carp is a bunch of small fish, sometimes even shrimp, crab and other seafood when caught by fishermen. This is a famous specialty of the coastal city of Quang Ninh, also commonly known as fishing boat hot pot. 5. Cuckoo Candy Cu Do candy is a specialty peanut (peanut) candy of Ha Tinh province. Candy is cooked from molasses, sugar, malt, ginger with peanuts added and poured into two pieces of pressed rice paper. This candy is very sticky and sticky, can be eaten alone or enjoyed with green tea. 6. Thang Co Thang Co is a specialty of the Mong people originating from Yunnan (China). The name of this dish is pronounced according to Sino-Vietnamese pronunciation as “thang co”, which means “bone soup”. The main ingredients of Thang Co are from the internal organs of horses such as heart, liver, blood, heart, meat, … combined with many typical spices such as cinnamon, lemongrass, cardamom, lemon leaves, ginger, … and victory tree. 7. Pig steals armpit The armpit pig, also known as Muong Sa Pa pig, badger pig, whistle pig, and ri pig, is a specialty pig breed of the highlands and appears most often in Lai Chau. This is essentially a traditional pig breed that was crossed between wild boar and Muong pig. Upland people often raise them freely in the forest, and because pigs have a small appearance, weighing only about 10-15kg, they are often “stolen in the armpit” for convenience. People often cut pork to make many different dishes such as steaming, grilling, cooking imitation civet, stewing soup, making sausages, but the most delicious dish is the fragrant roasted pork armpit. 8. Great-grandchildren The great-grandson at first glance looks exactly like a mussel but is a bit smaller. They usually live mainly in brackish and freshwater riverbeds in Quang Binh and Quang Tri. To get the cut meat, it is necessary to first wash it thoroughly, bring the pot of water to a boil, then pour it in, beat with chopsticks to separate the intestines from the shell, then treat (like rice) to remove the intestines. Particularly for the boiled water to settle, filter it and cook soup with young jackfruit, spinach or porridge. In addition, local people also use great-grand meat to cook delicious stir-fry dishes.

Americans call the unexplained neurological problems experienced by US diplomats in Cuba in 2016, including dizziness, ringing in the ears, headaches and nausea – sometimes combined by a ” the mysterious but more serious noise…, is the “Havana Syndrome”. Notably, in 2018, some US employees working in a few countries other than Cuba such as China (in Guangzhou) also reported experiencing similar symptoms – dizziness, lightheadedness, fatigue, or fatigue. headaches and blurred vision, memory loss and difficulty concentrating; some even face severe vision and hearing loss; children in the home had nosebleeds – prompting the Donald Trump administration to allege that diplomats were attacked with a secret weapon. In the late 2010s, US and Canadian diplomats experienced health problems of unknown cause; Source: stellariasacademy.online Mosquito repellent may be the cause of a mysterious illness that affects about 40 US and Canadian diplomats in Cuba, according to Canadian government research. Scientists from Dalhousie University and the Nova Scotia Health Service studied Canadian victims and also the brain of a pet dog after death. The results showed that these people lacked cholinesterase – an enzyme necessary for the functioning of the nervous system. Some pesticides work by inhibiting this substance. During the 2016-2018 period, Cuba stepped up the spraying of disinfectants to prevent the spread of Zika. That was also the time when diplomats had unusual symptoms. It is not clear if Cubans will be affected by the disinfectant, but the Canadian team of scientists is planning to work with Cuban scientists to further investigate the issue. Returning from Guangzhou, American diplomats were only allowed to take unpaid leave instead of receiving treatment and rehabilitation. The Trump administration also did not launch an independent investigation into the cause of the incident. American diplomats who had to be evacuated from Guangzhou are still fighting for not receiving the benefits they deserve compared to victims of the “Havana Syndrome”; US diplomat Mark Lenzi filed a lawsuit against the State Department. Meanwhile, some medical experts and US officials believe that this is just a psychological disease that is formed in a stressful working environment abroad. According to the New York Times, the University of Pennsylvania Brain Injury Rehabilitation Center has received 44 American diplomats returning from Cuba and 15 returning from China. Here, treating doctors declined to comment in detail, but rejected the theory of a psychological illness. According to them, these patients all experienced brain injuries due to external influences. Symptoms Similar to “Havana Syndrome” The Pentagon and other agencies that are investigating the incidents have not yet discovered or released details, but the suspicion of an attack that happened too close to the White House is of interest, especially for these reasons. familiar – terrorism. In early April 2021, the Senate and House Armed Services Committees were briefed by Defense officials, possibly including an incident that happened near the White House. The latest symptoms similar to “Havana Syndrome” have been reported near the White House, for some; Source: news.com.au The incident happened on the Ellipse – the large oval lawn south of the White House – where the “energy attack” took place that made a National Security Council official fall ill, according to several current officials. current and former US official with CNN. A female White House official also reported a similar incident in 2019, when she was walking her dog in suburban Virginia, according to a GQ report from 2020. All people who have experienced symptoms These witnesses all report their experiences to the CIA and the foreign personnel department of the State Department, to quickly open investigations into possible “Havana syndrome” attacks. A study by the National Academy of Sciences in late 2020 found that the illness that American officials contracted in Cuba, still known as “Havana Syndrome,” could be the result of microwave radiation. The document also says that the Soviet Union studied the effects of radio frequency energy 50 years ago – meaning any country, group or entity with similar technology could be behind the attack. power station near the White House and elsewhere. Microwaves are a type of electromagnetic radiation. The human eye can only see a small fraction of electromagnetic radiation – as visual light. But today, microwaves are in common everyday use – including telephone and television communications. Industrial applications include potato processing, plywood drying and curing, bread and donut making, etc. Sonic weapons may be the cause of the incident at the White House A directed-energy weapon that uses microwaves can quickly heat up parts of the body – especially those with less blood flow, like the ears, testicles, or brain. But more likely, the microwave during the “Havana Syndrome” event – and possibly the event near the White House – was the use of sonic weapons, or long-range acoustic devices. Is it true that “Havana Syndrome” is caused by a mysterious weapon?; Source: stellariasacademy.online Jai Galliott, director of defense and technology assessment and a former Australian naval officer at the University of New South Wales, said in an ABC report that sonic weapons can cause lung and liver damage. if set to the appropriate decibel (unit of sound measurement). Galliott adds, it has been shown that sustained low-frequency exposure over a long period of time can have other effects on the brain, and potentially brain tissue. And these weapons are real. The technology has existed since the 1970s and entered public discussion in the 1980s. But because the technology is still in the near-monopoly of the eyes of high-ranking government officials – like the Ministry Defense (DoD) or Central Intelligence Agency (CIA) – it is not easy to determine exactly how the weapons and symptoms of the White House event are causally related. “It’s not particularly complicated technology, it’s more about how they use it [và] effects they used to use [điều đó còn khó hiểu hơn]”; “Definitely Russia has that technology, the US has that technology, and also China,” Galliott explained to ABC. While it’s too early to say which devices, if any, caused the debilitating symptoms experienced by US officials near the White House and elsewhere in the previous months, we could be on the way. into a new era of discreet yet effective attacks on high-ranking officials – leaving no trace of the actors to blame. It is possible that the energy attacks were carried out from a low-flying drone, or a nearby operator, although this is only speculation. Canadian diplomats said their government had more detailed information on brain injuries caused by “Havana Syndrome”, but gave no further details.

The software helps to record the thoughts in the brain into writing on the computer. The combination of mental effort and modern technology has allowed a motionless man (T5) to communicate by text at a speed comparable to that of healthy colleagues texting. on smartphone. Study participant (T5) almost lost all mobility below the neck because of a spinal cord injury in 2007. The scientists placed two brain-computer interface chips, each about the same size. an aspirin pill, on the left side of T5’s brain. Each chip has 100 electrodes that pick up signals from trigger neurons in the motor cortex, an area on the outermost surface of the brain that governs hand movements. Those neural signals are sent over wires to a computer, where artificial intelligence algorithms decode the signal and infer the T5’s intended hand and finger movements. Algorithms were designed in Stanford’s Neural Prosthetic Translation Lab. T5 generated text at a rate of about 18 words per minute (the average person can say about 23 words per minute on a smartphone). Even, T5 then reached a record of 40 characters per minute. The study was published online May 12, 2021 in the journal Nature. It offers hope to hundreds of thousands of Americans and millions around the globe, who have lost the ability to use their upper limbs or speak due to spinal cord injury, stroke or amyotrophic lateral sclerosis.

Coc lake Address: Bung Rieng, Xuyen Moc, Ba Ria – Vung Tau. About 120 km from Ho Chi Minh City. Campsite cost: 100,000 VND/person. Highlights: The campsite is located on the coast of Ho Coc, a pristine beach that has recently been put into tourist exploitation. It has an extremely cool climate thanks to the surrounding mountains and forests. Because it has just begun to be invested and exploited, the scenery here almost retains the inherent wildness, with the long coastline and rows of blue poplars. Comment: Duong Lam: “The sea wind is strong at night, quite cold. There are not many restaurants around, so finding food and drinks is a bit difficult. Camping teams can consider buying materials in advance to be more satisfied. Ho Lam: The campground does not have a specific address, need to contact first to get the location coordinates, then follow the instructions on the map. The road to the campsite is mostly a rather deserted forest road, so it is necessary to prepare carefully in case of vehicle breakdown along the way. Fresh camping ground surrounded by poplar forest. Photo: Minh Hanh Phan. Dau Tieng Lake Address: Duong Minh Chau, Tay Ninh. About 100 km from Ho Chi Minh City. Campsite cost: 30,000 – 50,000 VND. Highlights: Dau Tieng is the largest artificial lake in Vietnam, not only plays an important role in irrigation, which is to coordinate water for the Saigon River, but also a tourist attraction that attracts many tourists. With wide lawn stretching, Dau Tieng lake is very suitable for camping. From the campsite, you can see Ba ​​Den mountain and green forest. The scenery is poetic and majestic. Currently camping at Dau Tieng Lake has more fun activities such as SUP paddle, tent rental, kayaking… The camping site is separate but close to residential areas, so buying more necessities is quite easily. Comment: Ms. Le Ai: Many campers will worry about going to the toilet. There are many shops around the camping area of ​​Dau Tieng Lake, so take advantage of cleaning and bathing during the opening hours. You can find dry firewood around the camp area, but please check the weather forecast to avoid wet firewood that will make it difficult to set up the stove. Mr. Vu Long: Camping, cooking, singing, hanging out with friends here is great. However, here the phone signal is very weak, sometimes lost. In the past, the beach was still wild, so the service was almost nonexistent, now the service is a lot with many things arising, so if you go self-sufficient or have no experience, you should contact tourguide for advice and guidance great experiences in Dau Tieng Lake. Beautiful sunset on Dau Tieng lake. Photo: Hai Tran, Vo Duc Huy. Tri An Lake Location: Dong Nai. About 70 km from Ho Chi Minh City. Campsite cost: no cost. Highlights: Tri An Lake is an artificial lake located on the Dong Nai River. The calm lake surface with clear water, the shady shore of the green trees are the ideal factors for a leisurely camping on a hot summer day. Tri An Lake is very large, but most of the campsites are located in the area from the hydroelectric power station along the canal to the edge of the forest. The space here is airy and spacious, suitable for watching the starry night sky or making a campfire to bake potatoes, barbecue… Comment: Mr. Nguyen The Son: In addition to the familiar campsites, people can camp along the canal. Especially in the dry season when the water recedes, you can go deep into the canal to plug. However, young people who come to camp should maintain general hygiene, before leaving, please clean up. Ms. Minh Anh: At the weekend, when I wanted to escape the city and find a quiet place to relax my mind, I encountered a group of groups with loudspeakers playing loud music. In addition to being affected by noise, the scenery at the lake is most beautiful at sunset. Tri An Lake with cool blue water, suitable for summer camping. Photo: Vu Thanh An, Nha Khuu. Cu Lao Cau Address: Tuy Phong, Binh Thuan. About 240 km from Ho Chi Minh City. Campsite cost: No cost. Highlights: Cu Lao Cau is a small island in Tuy Phong district, Binh Thuan. The island is nearly 10km from the mainland, so moving to the island is quite convenient. The island is pristine with blue sea water, surrounded by countless rocks of different colors and shapes. The stones here have many strange shapes and colors, changing unusually depending on the light every day. Long sandy beaches are suitable places for camping with friends on a sunny summer day. Comment: Mr. Kim Vu: There are currently only a few households living on the island, there are absolutely no restaurants, if you go camping on your own, consider buying enough food and water for the members in advance. After bathing, you can go to the border station to ask for fresh water, but you should save because water on the island is very scarce. Ms. Le Vy: Because the island is unspoiled, it is possible to encounter snakes and insects. Everyone should be well prepared for the worst case scenario. The coral on the island is well preserved, so it is very beautiful. You should prepare a pair of beach sandals to avoid injury when scuba diving. Unspoiled Cu Lao Cau is suitable for teams who love to explore nature. Photo: Khanh Tuan, Pham Vinh.

In their paper in the journal IEEE Trans Transaction on Biomedical Engineering, the team presented the results of trials on two men with spinal cord injury aged 35 and 63. The system works by connecting a signal generator on the user’s head to an electrode relay in the cortex, through the connection port like wired systems. From there, the tester can move, click and type on the computer keyboard with his or her brain. Transmitter connects to a relay located in the brain cortex, helping people to use wireless computers. Photo: BrainGate. In the test, both candidates were able to achieve typing speed and click accuracy on par with a wired system. At the same time, they can use the system continuously for up to 24 hours at home. “The signals are recorded and transmitted with the same fidelity as a wired system, meaning we can use the same decoding algorithms that we have,” said John Simeral, who leads the team. used with conventional wired equipment ”. “The only difference is that we are no longer physically tied to the devices, which opens up new possibilities for future research,” Simeral added. “With this system, we are able to look at brain activity at home, over the long term, in a way that was previously almost impossible,” said Leigh Hochberg, another team member. This gives us more opportunities to create algorithms that allow people with paralysis to move and work. ” According to the Mashable, The aforementioned study is a significant step forward in the field of neural communication, in which the human brain is directly connected to the computer. Recently, big names in the tech world like Facebook and Elon Musk have also expressed interest in this area. Simple device is placed on top of research candidate. Photo: Radiofiji. In 2020, Elon Musk’s startup Neuralink introduced a pig named Gertrude, with a computer chip implanted in the brain. Or, as before, in 2021, the company also succeeds in implanting a chip into the monkey brain so that the animal can play video games. However, Brown University’s first human study demonstrates that the technology can be used wirelessly, and it wouldn’t be surprising if we find wearable devices that allow people with disabilities to communicate with them. continue and work better in the future.

Super smart city model on 6G infrastructure. Although 5G technology has not even been widely available to users, a fierce race for the 6th generation (also known as 6G) mobile network between the leading countries in technology has begun. head. “FORGET 5G”, US WANT TO GO 6G In theory, the 6G network could be 100 times faster than the maximum speed of 5G and is expected to provide many technological applications that have long been seen as science fiction. Such as real-time holograms, flying taxis, and the ability of the human body and brain to be connected to the Internet. Until now, the race to 6G is increasing, especially between the US and China. There are even more concerns: 6G is so important that it has become an arms race to some extent. In this tech race, the United States will likely hamper Huawei’s 6G ambitions just as it has proven it is capable of hurting Chinese tech firms in the past. 6G has clearly been on the minds of policymakers in both Washington and Beijing. Former President Donald Trump shared on Twitter in early 2019 that he wanted 6G “as soon as possible”. The development of 6G could give America the opportunity to regain its lost position in wireless technology. Vikrant Gandhi, Senior Director of Information and Communication Technology Frost & Sullivan said: “ The United States missed the opportunity to lead the 5G wireless technology, and this time they are determined to focus on 6G development. Competition for the 6G lead will be much fiercer than 5G. It is easy to see that Washington started with the “Telecommunications Industry Solutions Alliance” called ATIS and launched the Next G Alliance in October 2020 to “elevate North American leadership in technology. 6G “. The members of the alliance including tech giants like Apple Inc., AT&T Inc., Qualcomm Inc., Google and Samsung Electronics Co., of course, never had Huawei. According to Bloomberg, China also took the lead by launching a satellite in November last year to test the transmission of 6G. In addition, telecommunications equipment maker ZTE Corp has partnered with China Unicom Hong Kong to develop a new generation of technology; Huawei also has a 6G research center in Canada. However, in this tech race, the US may hamper Huawei’s 6G ambitions as the country has shown it is capable of detrimental to Chinese technology firms in the past. KOREA AND CHINA HAVE ADVANTAGES IN A 6G RACING Samsung Electronics and Huawei Technologies are two leading names in the deployment of BTS stations, which are important infrastructure of telecommunications networks. According to the Nikkei, Korea and China will have an advantage in the 6G technology race. Japan and the US will have difficulty if they want to catch up with these two countries on 6G. Currently, Samsung is leading in 5G copyright, holding 8.9% of the number of copyrights. Huawei came in second with 8.3%, Qualcomm with 7.4%, while Japan’s NTT Docomo came in sixth with 5.5%. South Korea is hoping to become the first to offer commercial 6G services, with corporations Samsung and LG setting up research centers and the government considering investing 976 billion won (18,687 billion dong) in development projects. Beijing also announced its 6G network research and development program last November, and Huawei launched a dedicated research team. According to Tetsuya Kawanishi, telecommunications expert from Waseda University (Japan), BTS stations are expected to change both quality and quantity to be compatible with the 6G network. Japan currently has about 600,000 BTS, but to properly meet the 6G infrastructure, 1 billion stations are needed, while the world will need 100 billion stations. Theoretically, a 6G network can reach more than terabits per second, 10 times faster than 5G. But in terms of coverage, the transmission distance of 6G base stations will be only 200 m or less, and using shorter wavelengths, smaller antennas. Therefore, lighting equipment, signs or passenger cars can also add BTS to increase the coverage. According to HIS Market market research company, three companies including Huawei, Ericsson (Sweden) and Nokia (Finland) account for 80% of the BTS market share and many companies are racing to develop smart stations. to lead the race in this segment. SUPER EXPLOSION 6G NETWORK CONNECTION Four main orientations on connection are being studied by countries around the world, including: smart connection, deep connection, heterogeneous connection and connecting everywhere. Most likely, the technologies of the future are considered to be included in the 6G network such as optical wireless communications, quantum communications, unmanned aerial vehicles, low-rise satellites … Moreover, artificial intelligence and big data analytics are also included in the 6G network support to ensure network quality goals. Most likely, the technologies of the future are considered to be included in the 6G network such as optical wireless communications, quantum communications, unmanned aerial vehicles, low-rise satellites … Since then, many super smart applications based on 6G platforms such as: smart home will be widely deployed when smart devices are able to connect and control remotely; Intelligent traffic with control systems, autonomous vehicles, flying taxis; Smart city is built on environmental monitoring systems, optimal energy control systems to improve people’s living standards. Augmented reality technology also requires a 6G network. In addition to the objects being 3D simulated and controlled by artificial intelligence, the user experience will be supported by all 5 senses of hearing, seeing, smell, taste, and touch through sensors. With high bandwidth speed, low latency, 6G network will ensure the quality of user experience. The wireless communication features of the 6G network allow the technology of tomorrow to be the brain and computer interface system (BCI) in everyday life. BCI takes signals from the brain and sends them to digital devices, analyzing and interpreting the signals into device control commands. Moreover, integrated satellite network will allow 6G network to have global mobile coverage; convert and upgrade conventional connections into smart ones; integrated power and information transmission, not only allowing information transmission but also wireless power transmission to charge devices.

Indian dance ants. The new owner of the throne has the ability to expand the ovaries, reducing the size of the brain to take over the responsibility of reproduction for the whole herd. The battle for the throne Ants have a relatively simple “class” distribution system. While the queen is responsible for laying eggs, the rest of the herd must find food, feed the ants, join the battle, and build nests. Only male ants and queens are capable of reproduction, and other ants cannot. If the queen dies, the whole herd must suffer the same fate. Similarly, the Indian dance ants (Harpegnathos Saltator scientific name) include queens, reproductive males and a group of worker ants who are females. Queen ants hold the highest position in the ant colony, living 5 times longer. Only it is allowed to give birth. In most species of ants, the queen is born, not chosen from a herd. However, the Indian jumping ants allow worker ants to compete for a chance to sit on the throne, becoming a queen ant. Research published in the scientific journal Proceedings of the Royal Society B: Biological Sciences in early April showed that, in this species, if the queen died, about 70% of the female ants in the herd would compete for the throne. . The fight lasted for about 40 days. The opponents used the beard to fight until the competing group had 5 – 10 remaining. These animals continue to spend the next days to reproduce because the ovaries are enlarged while the brain shrinks up to 25%. After the war, the winning child will expand her fertility like a queen and become the second queen. The others return to being a worker, so the ovaries shrink and the brain enlarges again. Professor Clint Penick, the lead author of the study, commented: “This is an unprecedented miracle in the insect world. The toughness of this species allows them to swap roles in the herd. Professor Penick has spent many years studying the Indian dance ants. When worker ants become queen ants, they are called “gamergates”. All worker ants in the herd are capable of reproduction, but they are only allowed to do so when they win the throne. In the natural world, many species of insects, like bees, also compete for dominance. But the jumping ants fight to give birth, which really impressed the scientific experts. When a gamergate becomes a queen, its body goes through a complex transformation process. The queen will stop producing the venom, change its behavior like evading intruders, not hunting. Notably, their brains shrank by 25%, while the ovaries were enlarged by 5%. Indian dance ants can shrink the brain, enlarge the ovaries. Looking for a solution To analyze the queen ant transformation, Penick and his team selected 60 gamergates, painted them to distinguish them, then quarantined them for several weeks. When isolated, gamergate decreased fertility. But when they returned to the herd, they were captured and imprisoned by the worker ants. Penick explains that the gamergates are being controlled by the whole herd. The worker ants stopped the other ants from reproducing because this behavior was beyond the queens of the queen ants. If it was discovered that a member with the same function as the queen ant, the worker ants would bite and detain it for many days even though it did not endanger its life. Scientists hypothesize that this behavior causes a series of internal changes to the gamergates, making them likely to become queen ants but also as worker ants. The transformation happens in a few days. The reason the Indian jumping ant’s brain can shrink is because the gamergate does not have to use the brain to forage, protect the nest from predators. Their main job is to reproduce, while worker ants need large brains to think about these problems. Another reason gamergate shrinks the brain is to conserve energy. This behavior has also been observed in the Etruscan shrew, a small mammal. Their brains shrink in the winter to limit energy, helping to keep other parts of the body warm. Some other animals also have the ability to change brain size such as ground squirrels, birds. White-crested sparrows, for example, create 68,000 new nerve cells during the breeding season to help them recognize mating calls. In winter, when food is scarce, some of the nerve cells die on their own, and in the spring, they revive again. But this phenomenon is rare in insects such as ants. While Rachelle Adams, a researcher in ant evolution and ecology at Ohio State University, thinks maybe this behavior is not as special as we think it is. The problem is that scientists have not fully understood and discovered about the Indian hopping ants may be the foundation for further research in this field. As brain modification is studied more and can be found in many different species, it will have special significance in understanding the human brain. For example, research into the brains of the Indian gerbil helps to understand more about genetic control, the ability of genes to control flexibility in animals and towards humans.

“Doctor, what can you eat during pregnancy to make your baby smarter?”

“Can eating folic acid make babies smarter? How about DHA?”

Every pregnant mother wants her child to be smart and beautiful. However, what factors will affect the baby’s brain development?

Professor Sun Lizhou from Jiangsu Provincial People’s Hospital once delivered a speech “Risk Factors Affecting Fetal Brain Development during Pregnancy”.

Explained in detail which factors will affect the IQ of the fetus, and even affect the development of the nervous system.

Do you know the period of fetal brain development? From a fertilized egg to a fetus, it undergoes cell proliferation and differentiation. From the B-ultrasound, the baby’s changes can also be observed. But, do you know when the baby’s brain development begins? In fact, at the 4th weekend of the embryo, the baby’s brain bubbles are formed; In the 5th to 6th week of the embryo, the forebrain vesicles form the left and right telomeres; By the 7th week of the embryo, cerebral cortex tissue has occurred; At the 8th week of the embryo, the cerebellum occurs; At the 12th week of the embryo, the cerebellar hemisphere and cerebellar vermis are formed; The weight of the brain at birth is about 25% of that of an adult, and by the age of 2 it increases to about 75% of that of an adult; At the age of 1 year, the DNA level of the brainstem reached the adult standard, and at the age of 4, the DNA level of the forebrain and cerebellum reached 75% of the adult. It can be seen from the figure that the neurodevelopment of the fetus begins in the first trimester and covers the entire fetal period until 3 years after birth. Moreover, the fetal period is an extremely important period for brain development.

What factors affect fetal brain development? The baby communicates with his mother through the placenta in the womb. The outer layer of the placenta is mainly composed of maternal cells, and the inner layer is composed of fetal cells. The state of the mother will affect the state of the placenta, thereby affecting the development of the fetus.

Risk factor 1: weight gain during pregnancy

Too much or too little weight gain during pregnancy can cause adverse health problems for mothers and babies.

The mother may have postpartum weight retention, increase the risk of cesarean section, increase the risk of gestational diabetes and high blood pressure.

The effects on the fetus include: birth volume larger or smaller than gestational age, increased risk of premature birth and childhood obesity risk.

The American Institute of Medicine (IOM) has published a guideline recommendation for weight gain during pregnancy:

In addition, a review of 12 studies proved that obesity during pregnancy is related to the baby’s future cognitive, behavioral, and emotional development. And it will increase the risk of behavioral and cognitive deficits in childhood.

Therefore, the weight gain of pregnant mothers during pregnancy must be reasonable. Don’t just eat and drink just to make your baby grow up and grow stronger; don’t over-control your diet just to keep your body in shape.

2

Risk factor 2: Cesarean section

Caesarean section will also affect the baby’s brain development?

This is a conclusion based on the results of a large number of studies. Cesarean section not only affects the early stage of the baby, but also increases the baby’s risk of developing some diseases in the long term.

Studies have shown that cesarean section is related to autism spectrum disease. It is possible that the oxytocin injected during cesarean section will change the balance of oxytocin in the newborns, thereby affecting the brain development of children.

The picture shows the risk comparison of autism spectrum diseases (ASDs) in newborns with different delivery methods

In addition, due to the birth without the natural birth canal, the ability of the newborn to adapt to the external environment may be reduced after birth, and the early behavioral ability is slightly lower than that of the newborn born naturally. But this is transient, don’t worry too much.

There are also research results that show that cesarean section surgery may damage the intellectual structure of children. Babies born under cesarean section have lower IQs in terms of number breadth and memory/distraction factors than those born naturally.

Therefore, if you can live by yourself or live by yourself!

However, when there are medical indications for cesarean section, it is still necessary to weigh the pros and cons and follow the doctor’s advice.

Risk factor 3: Complications during pregnancy

Complications during pregnancy include: gestational hypertension, gestational diabetes, intrauterine infection, and others, such as thyroid disease during pregnancy, abnormal psychological conditions during pregnancy.

Although most pregnancy and childbirth can go through smoothly, about 15% of pregnant women will have life-threatening complications during pregnancy. Not only will it threaten the life of the mother, but also affect the normal development of the fetus.

▎Pregnant hypertension:

Studies have shown that pregnancy-induced hypertension can increase the number of fetal brain neuronal apoptosis, cause neuronal damage, and affect the development of the nervous system.

The picture shows the comparison of brain nerve cells between normal fetuses and fetuses with perinatal asphyxia and preeclampsia

In addition, there are prospective follow-up studies that show that high blood pressure during pregnancy can cause about 30% of children to have IQ lower than normal at the age of 4.5.

▎Gestational Diabetes:

Studies have shown that gestational diabetes can cause memory impairment in infants.

A baby born to a mother with gestational diabetes does not have a big difference between the face of the mother and the face of a stranger.

A baby born to a normal mother during pregnancy will attract more attention when seeing the mother’s face.

The picture shows the total average data of 6-month lateral leads for normal babies and babies born to gestational diabetic mothers. The infants in the control group showed larger negative components when facing their mothers or strangers, indicating that the mother’s face attracted more attention of the infants.

In addition, the control group infants had greater differences in memory renewal (PSW) to their mothers or strangers, but there was no significant difference in infants born to gestational diabetic mothers, indicating that memory and cognitive functions were impaired.

At the same time, about 50% of babies born to pregnant women with gestational diabetes will suffer from neonatal hypoglycemia. The longer the period of neonatal hypoglycemia, the greater the impact on brain development.

In addition, studies have shown that hypertension, diabetes, and other metabolic disorders during pregnancy are related to autism and growth retardation in the offspring.

▎Intrauterine infection:

Mothers infected with Toxoplasma gondii, rubella, cytomegalovirus (CMV), herpes simplex virus (HSV) and other microorganisms during pregnancy can cause mental retardation, cerebral palsy, enlarged ventricles and other brain and behavioral abnormalities in the offspring.

Studies have shown that intrauterine infection can cause the baby’s neurological disease and the risk of cerebral palsy to double.

Especially this year’s new crown epidemic, the long-term impact on the baby is still unclear, and further follow-up studies are needed.

▎Thyroid disease:

Thyroid function itself will affect the brain development of the fetus. Hypothyroidism and subclinical hypothyroidism during pregnancy need to be corrected in time.

It is best to perform a thyroid function test before pregnancy and follow-up screening during pregnancy.

A prospective birth cohort study showed that the mother suffered from hypothyroidism in the first trimester, and the IQ value of the children born during the school age decreased by 4.3.

Risk factor 4: Intrauterine growth restriction (FGR)

Intrauterine growth restriction has a high incidence in developing countries and is a common adverse pregnancy outcome.

Some scholars compared the brains of children with FGR, full-term infants, and premature infants by MRI and found that:

Compared with full-term children, FGR children showed reductions in bilateral temporal lobes, hippocampus, amygdala, right central area, right frontal lobe, left parietal lobe, and basal ganglia.

Compared with preterm infants, children with FGR showed that the amygdala, basal ganglia, thalamus, insula, bilateral angular gyrus, left occipital and parietal lobes, and right central area were all reduced in volume.

The picture shows the MRI comparison of FGR infants, term infants and premature infants

All in all, FGR will cause the volume of brain gray matter to decrease, and the brain volume is lower than that of normal babies. This will affect language communication skills and increase the risk of neurodevelopmental disorders.

summary

There are too many factors that affect fetal brain development during pregnancy!

However, Professor Sun Lizhou also summarized 4 intrauterine environmental factors for pregnant mothers to ensure normal fetal brain development:

Keep away from toxic substances;

Avoid infection with pathogenic bacteria;

Proper nutrition;

Sufficient oxygen.

I wish every little baby come to this world healthy and safe~

According to Wikipedia, Déjà vu is the French word, meaning “seen” or known as hallucinogenic memory or promnesia (dementia) is hallucinogenic, feeling familiar (as seen, experienced in memory) in a new setting, never known before or not remember when. This is the experience of a sure feeling of having witnessed or lived through a situation that has happened before, even though it is not possible to know with certainty when those premonitions occurred. The term Déjà vu was named by a French psychic expert, Émile Boirac (1851-1917), as he stated in the book L’Avenir des sciences psychiques, which was born when Boirac also a university student. Déjà vu is often a very familiar, but “strange and mysterious” feeling, occurring frequently in dreams and in real life, in both adults and children. Déjà vu has been described in literature for a long time, but it is a topic that causes a headache for scientists, especially psychologists today. Recently, researchers have discovered a way to create this feeling through hypnosis. From the late 20th century, déjà vu has been studied deeply in psychology and neurology. Scientifically, the most accurate explanation for déjà vu is not that it is the “foresight” of the action or of the “foreseen” talent, but an anomalous defect of memory that keeps humans from creating. gives the impression that the memory is “being recalled”. The Déjà vu phenomenon can take place both in real life and in dreams There is also an opinion that in the process of daily life and communication, the human brain has the ability to arrange, link events and analyze logically, thereby creating images and sounds. …, likely in the future and recorded in memory, this is almost identical to the method of prophecy. This human brain’s ability to self-align and connect is formed and trained during deliberate thinking and speculation (such as betting on something). So, when we come across one of the things the brain has properly analyzed (there may be some false positives, this explains why only sometimes we come across déjà vu), then we will feel “as if” met or been in that situation in the past. Some assumptions and facts related to déjà vu 1. Déjà vu is deceived by the senses? There is a particularly vague theory, that déjà vu is a simple phenomenon in which the senses in the body “play pranks” on people. Usually, human feelings and perceptions of the world are not distinct, in which the senses play a key role. For example, when we walk into a strange bakery, we smell the delicious aroma of freshly baked cakes. Perhaps it matches the same taste as it has been smelled before, the brain is trying to recall the exact taste, it feels as if you’ve seen it before. The above phenomenon is similar to when we hear a specific noise or a certain conversation tape, it feels like we have heard in the past without being able to recall, all of these phenomena are convincing. that the subject has experienced this moment. It is the simplest and easiest to understand hypothesis, and like most of the other assumptions about déjà vu, the senses in the body have “prank” on humans with practically no way to test. OK. 2. Is Déjà vu a simple cataloging error? Another theory is that the brain’s long and short-term memory circuits may be subjected to an issue that causes the brain’s librarian to malfunction, creating simple cataloging errors, like editing errors. If the brain is damaged, the insider is very common to déjà vu Let’s say you’re going to a party in a luxury apartment with brand new people you’ve never met. However, when you enter, you are overwhelmed with the feeling that you have been at a time similar to what happened before. The interior layout of the room, the number of musicians playing, everyone happily with a glass of wine in hand … you will be convinced as if you have experienced before in the past, it is déjà vu is taking you into the game. What happened makes us feel déjà vu, your brain is not doing its own function well. The human brain has a hard-to-clean memory system, which is a series of storage transformation mechanisms that, like almost anything else in the world, sometimes make mistakes. The brain can store new information when you join a party, but it does so into long-term memory catalogs, giving insiders the feeling that this event has happened, sometimes during the process. distant past. 3. Human memory is not good One prominent and quite basic theory is that human memory is not good. Concerning this hypothesis, news site Smithsonian.com Take an example from Colorado cognitive psychology professor Anne Cleary to explain. Suppose, you are taking a trip to Paris for the first time and visiting the Louvre. When you stare at the glass pyramid, people get a familiar feeling déjà vu, even though you have never been to the Louvre before, why is this phenomenon? Chances are your brain may not be able to find vital memory, which might explain why the Louvre is so familiar. Perhaps, as Cleary pointed out, if you had seen the Da Vinci Code a few months ago, which mentioned the pyramids and in the same case, it feels as familiar as one. something has been seen before. Actually, the memory is not good, doesn’t make the exact distinction. Another phenomenon that arises déjà vu is because parts of the brain work out of sync. The Rhinal cortex region that is responsible for activating the familiar activity sometimes malfunctions like an electronic device. It is activated without waking up the other memory processing areas to work together. That may explain why it is so difficult to describe the feeling when meeting déjà vu, it is often a vague familiarity, but not focused on a particular object or object. 4. Déjà vu is a manifestation of epilepsy On the lesser-known side, people with epilepsy experience a more familiar and more frequent feeling of déjà vu than people without the disorder. According to research, many people with epilepsy report a feeling of déjà vu before the seizure begins. In fact, the link between epilepsy and déjà vu has been mentioned since 1888, although human medicine was back then, did not know how to examine the brain and what about déjà vu is still very much. primitive. Specifically, the medial temporal lobe is considered the culprit, this is the part of the brain involved in sensory perception, speech language creation, and memory matching. During epilepsy, neurons are blocked, resulting in a mess of messages that are passed around the body. Déjà vu can be the result of a nerve cut across the face, the culprit causing epilepsy, and once nerve overlaps are the cause of déjà vu. 5. Chronic déjà vu is caused by brain damage Chronic déjà vu is a serious disease and also a form of proving that the neural mechanism is the culprit of the “back against” déjà vu recurrence. In extreme cases, people with chronic déjà vu often refuse to read newspapers or watch television, because they always feel like they’ve read or watched everything before. Even the act of going to the grocery store is a pain for this group of people, because it is impossible to distinguish which items have been bought and not purchased. In such cases, déjà vu overcame the interesting threshold, happened randomly and became a true disease. And, like most diseases in medicine, it must have a specific cause. Researchers have found that people with chronic déjà vu experience brain damage, especially those in the temporal region or the anterior area. Because blood vessels involved in memory and familiarity are damaged, and often disabled, patients often feel déjà vu, even making their daily lives difficult. than. BS. BEARING ( According to Grunge.com- December 2017 )

The study was performed on 104 children aged 3-10 years old, of which 55 were girls. The scientists showed the children an educational video that included math concepts such as counting and subtraction. The scientists then charted the child’s brain activity through an MRI scanner and compared the results. That data showed no difference between children’s brain functions or development. The team also looked at the results of a math proficiency test of 97 children aged 3 to 8, of which 50 were female. Both genders showed equally good results, irrespective of age. The study also showed that, in fact, girls and boys had similar levels of neurological maturity across the brain. This shows that the neural processing of mathematics develops at the same rate in boys and girls. According to researcher Matthijs Oosterveen, Erasmus University Rotterdam (Netherlands), “Natural science has been considered a weakness of women. Many people believe that they are more endowed with social studies. Scientific findings show that it is gender prejudice. In fact, men and women are equally capable “. Dr. Alyssa Kersey – Psychology Department, University of Chicago said, “Not only in mathematics but in all other fields, both boys and girls have similar brain activity.” . According to research published in the Journal in 2011, gender stereotypes about math can cause girls to have more self-esteem about their abilities. In the long run, it will have a negative impact on their academic performance. Therefore, scientists hope that these scientific studies can contribute to eliminating gender stereotypes. Thereby, it is possible to promote women’s participation in the fields of science, technology, engineering and mathematics (STEM).

One case of a patient with hand, foot and mouth disease must be hospitalized for treatment. According to the health report in April 2021, just sent by the Ministry of Health to the Office of the Government, in April, the country recorded 64 cases of viral encephalitis, including 1 death in Ben province. Bamboo. It is also the first case of death from viral encephalitis this year. Cumulative since the beginning of the year, the country has recorded 145 cases of viral encephalitis, equivalent to the same period in 2020. In addition, this month also recorded 2 cases of meningitis due to meningococcal tissue but no death case. Cumulative since the beginning of the year, the country has recorded 8 cases of meningitis caused by meningococcal tissue (an increase of 4 cases compared to the same period last year), of which 1 case died in Ho Chi Minh City. Also in this month, the country recorded 3,728 cases of dengue fever, 2 fatalities. Accumulating from the beginning of the year up to now, the country has recorded 19,710 cases of dengue fever, 5 deaths in Binh Duong (1); Phu Yen (2); Soc Trang (1), HCMC (1). Compared to the same period in 2020, the number of cases has decreased by 16.3%, but deaths increased by 1 case. In addition, hand, foot and mouth disease in the country this month recorded 8,705 cases and 3 deaths. Cumulative from the beginning of the year until now, the whole country has recorded 20,756 cases of hand, foot and mouth disease, 4 deaths in Dak Lak (1); Kien Giang (2); An Giang (1). Compared to the same period in 2020, the number of cases of hand, foot and mouth disease nationwide has increased by 1.9 times. With suspected measles fever, the whole country also recorded 69 cases, of which 17 cases were positive, there was no death. Accumulated from the beginning of this year, the country has recorded 173 cases of suspected measles fever, of which 21 cases were positive, and no deaths were recorded. Compared to the same period in 2020, the number of cases decreases by 12.8%, the number of positive cases decreases 156 cases. According to the Ministry of Health, Vietnam is a tropical country, circulating many infectious diseases transmitted by insects, including viral encephalitis, especially in the summer, the season suitable for insect transmission. Viral encephalitis is a dangerous condition caused by a variety of viruses, often causing damage to the brain, resulting in neurological sequelae and high mortality. In order to proactively prevent and fight epidemics in the summer of 2021, the Ministry of Health has sent an official letter to the Department of Health of the provinces and cities to strengthen surveillance, early detection, isolation and thorough treatment of outbreaks. at the same time take samples for testing to determine the causative agent. In particular, the provinces / cities must step up the expanded vaccination, ensuring the rate of over 95% of the commune, ward and town scale and organize the campaign of environmental sanitation, mosquito elimination, and larvae. .

Psychological effects of patients Many people think that intestinal problems only affect physical health but in fact, the state of the microorganisms inside the intestinal tract is also possible through the vagus nerve and the intestinal nerve transmitted to the brain, thereby affecting human emotions and psychology. Research shows that: intestinal dysbiosis or a deficiency of certain beneficial bacteria increases the risk of depression than normal, healthy people. It can be seen that gut health needs more attention for you to live a healthy and vibrant life. Increased risk of heart and blood vessel disease Health experts recommend: Adjusting groups of bacteria in the gut in a balanced and reasonable level can improve the situation in patients with heart failure. In addition, the cases of miasma, anorexia, perforation, etc., were also mitigated. Therefore, gut health affects not only the digestive system but also the heart and blood vessels. Causes inflammation When the microbial environment in the gut is imbalanced, the pathogenic groups of bacteria can disrupt the stability of the mucosa, weakening the protective effects of this natural barrier, leading to the birth of the body. inflammatory response as a warning signal, long-term cause gastritis, chronic intestinal inflammation. In addition, intestinal dysbiosis also affects the efficiency of food digestion and absorption of nutrients by the body, resulting in harm to the overall health. You are susceptible to being deficient and developing many diseases. Affects brain function The nervous system of the brain is correlated with the immune and endocrine systems. Specifically, the brain can regulate the intestinal permeability, affecting the groups of bacteria inside the digestive system. Conversely, the gut microbiota can release internal hormones, which are like the way that the intestine and brain circulate, thus affecting brain function as well. What should sisters do to enhance the health of the digestive system and improve the balance of intestinal bacteria? Give the bowel time to rest No matter how busy women are, they should pay attention to controlling the eating time as well as the amount of food taken into the body. Besides practicing the habit of eating on time, the time between two meals should limit eating extra snacks. This is when your intestinal function has a chance to regulate and restore and digest food better. Besides, when you sleep is also when your intestines reduce the burden, so dinner should be finished before 20 hours is the most ideal, both help stabilize the digestive system and not affect sleep. In addition, each meal with only 7 servings is also beneficial for the health of the intestine and stomach. Eat slowly, chew thoroughly The habit of eating slowly, chewing thoroughly can cause saliva in the oral cavity to enhance the tolerance with food, reduce the pressure on digestion and absorption, and are also beneficial to enhance feelings of fullness. , helps you limit the amount of food you eat. A glass of warm water after waking up When you wake up early in the morning, you should drink a glass of warm water before doing personal hygiene and breakfast. This habit is not only beneficial for bowel problems but also effectively cleans the “garbage” in the intestines, prevents constipation and limits intestinal dysbiosis. Be physically active Women should base themselves on their health status to choose the right sport and sport. Every day should spend at least 30 minutes to move the body, promote bowel movements, reduce constipation and increase resistance, prevent disease. Supplement foods that are good for the gut Some foods with intestinal protective effects that you can choose from such as seaweed, black fungus, yogurt, etc. In addition, increase your intake of green vegetables and fruits so that your body has enough fiber, vitamins, minerals, helping to balance the microflora in the gut and stimulating the digestive system to function better.

Earlier on February 8, Gia Lai Provincial People’s Committee issued Decision No. 77 / QD-UBND on the implementation of the project “Building Pleiku city towards a smart city in the period of 2020 – 2025, with a vision to by 2030 ”. Accordingly, the project to build the city. Pleiku follows the direction of a smart city in order to exploit and bring into play its potentials and advantages, improve the efficiency of resource use, and protect the environment sustainably; improve efficiency of state management and urban services. Smart urban construction will make the city. Pleiku becomes a safe city, good management environment and complete tourism services. The IOC is officially put into operation. Speaking at the opening ceremony, Mr. Nguyen Huu Que, Chairman of City People’s Committee. Pleiku said, IOC is like a “digital brain” with the ability to integrate data and available systems with central control software, creating a panoramic view in all fields. In particular, the central function of the IOC will monitor, administer socio-economic indicators, monitor the effectiveness of government activities, manage and use land; operating community security and order; traffic Safety; interacting, communicating to serve citizens; monitoring of environmental quality; supervising, operating in the fields of health, education, tourism and information monitoring on the internet … Reflecting on areas is made easy through the IOC. It is known that IOC TP. Pleiku is designed, built, integrated and coordinated with the City People’s Committee by Viettel Group of Industry and Telecommunications. Pleiku to deploy. IOC’s facilities are invested synchronously with 12 46-inch screens, control equipment system, 4 specialized computers for data mining operation, 2 high-altitude cameras … Previously, the people of the city. Pleiku wants to reflect any problem must submit an application to the competent authority. This process not only takes a lot of time and travel costs, but also makes people afraid to go to public authorities. However, when the IOC center came into operation, especially through the Pleiku smart app, all people’s reflections on the fields were done very easily and quickly with just a simple operation. Smartphone or computer attached to field photos and videos. These feedbacks are received by the center and sent immediately to the leaders where the incident is happening. The process of receiving, processing and the results are posted immediately after that so that the people can monitor and give feedback.

The director, former deputy director, chief accountant of Bach Mai Hospital was arrested for overriding medical equipment prices and appropriating money from patients (Photo: Ministry of Public Security) This is the main content in the evaluation conclusion of the Rosa Robot surgery at Bach Mai Hospital, conducted by the Investigation Police Agency, the Ministry of Public Security. Collusion to “blow prices” on the pain of the patient The conclusion of the investigation of the criminal case, the request for prosecution of the Investigation Police Agency clearly indicated: Mr. Pham Duc Tuan – Chairman and Director of BMS Company – met with Mr. Nguyen Quoc Anh to offer to Bach Mai type robot Rosa costs 39 billion VND and Mako robot costs 44 billion VND in the form of joint ventures and associates. After that, Mr. Nguyen Quoc Anh decided to approve the joint venture to connect the device with BMS Company without going through the Party Committee, Board of Directors and Union of Bach Mai Hospital. Rosa robot imported by BMS Company from France to Noi Bai airport is 100% new and the original price is more than 7.4 billion dong, but it was agreed by Mr. Nguyen Quoc Anh and Mr. Nguyen Duc Tuan to bring to Bach Mai Hospital. at the price of 39 billion dong. Rosa robot is used in cranial surgery (Photo – medgadget) The investigation concludes that Nguyen Quoc Anh has created conditions for BMS to join the joint venture and install the machine at the wrong cost to collect money from the patient. / 2020, Bach Mai Hospital used this robot to perform cranial surgery for 639 cases, earning more than 22.9 billion VND. Bach Mai Hospital has paid the cost to BMS Company related to 551 surgical cases in the hospital. In particular, according to the assessment conclusion, the pre-surgery robot Rosa is more than 6.6 million VND / case but Bach Mai Hospital and BMS Company collect more than 23 million VND / case; enjoy the difference more than 16.5 million VND / shift. Up to now, Bach Mai hospital has just contacted, paid the difference above for 86 patients. Currently, the accused Pham Duc Tuan has paid 10 billion VND to pay the difference of 16.5 million VND for 551 cases of wrong collection. The police investigation confirmed: The behavior of the former Director of Bach Mai Hospital, BMS Company and other related subjects had an agreement, collusion, receiving each other’s will, taking advantage of the policy. mechanisms for socialization, joint ventures, and association in the health sector to act against the law, raise prices for medical treatment without a legal basis, cause property damage to patients and bring benefits to BMS Company and the same interest group in Bach Mai Hospital. Therefore, the Investigation Police Department has concluded, suggesting the Procuracy prosecute Mr. Nguyen Quoc Anh – former Director of Bach Mai Hospital – and 7 accomplices for the crime of “Abusing positions and powers in on duty ”under Clause 3, Article 356 of the Penal Code, occurred at Bach Mai Hospital. Is there a “gap” in medical socialization? The socialization of public services in general and in the health sector in particular is a right policy of the Party and State, contributing to mobilizing all social resources in the context of a tight budget. , to increase investment in facilities and equipment in order to improve the capacity and quality of medical examination and treatment services, to meet the diverse needs and increasing demands of all classes of people, as well as asking indispensable in approaching the world medical achievements of the medical team, doctors. Since 2007, Bach Mai Hospital has implemented many projects on socializing joint ventures, linking the installation of high-tech medical equipment, new techniques, helping patients in the country to be diagnosed. treat many complicated diseases at a lower cost than the overseas medical examination and treatment cost. Bach Mai Hospital (Photo – BVCC) The process of implementing a number of joint venture and medical equipment installation projects at Bach Mai Hospital has revealed the limitations, violations, and even committing crimes “Abusing positions and powers in on duty ”in implementing joint venture project, associated with BMS Company. Because Bach Mai Hospital is a special-class public health facility, the pressure of innovation and the expectation of patients of the family is great, so Mr. Nguyen Quoc Anh has directed the establishment of specialized surgical faculties to develop comprehensive development (Bach Mai Hospital was originally considered to have the advantage of internal medicine), attracting patients, increasing the income of the hospital and the income of the medical team. Therefore, Mr. Quoc Anh strongly agreed with BMS Company to install surgical assistive robots at Bach Mai Hospital, and at the same time, directed and requested Nguyen Ngoc Hien and the Accounting Department to implement the procedures for signing and putting the device into operation on February 27, 2017 (Vietnam Physician Day), bypassing the procedures and procedures in accordance with regulations. On the other hand, the fact that Mr. Pham Duc Tuan and the staff of BMS Company in the process of meeting with the leaders at Bach Mai Hospital with “external” money envelopes contributed to promoting the behavior of the defendants. From the above reasons, the Investigation Police Agency has pointed out that the main responsibility for the above-mentioned violation in the whole case belongs to Mr. Nguyen Quoc Anh – former Director of Bach Mai Hospital – the person with the highest authority. , decide policy, agree on equipment price with BMS, sign joint venture and association procedures. The case of the interest group at Bach Mai Hospital – headed by Mr. Nguyen Quoc Anh and BMS Company “blowing the price” of medical equipment to “eat” on the back of a serious patient has made public opinion frustrated. This incident is a warning bell on the risk of “gaps” in the socialization of the health sector not only at Bach Mai Hospital but also in other hospitals, in need of authorities. function to investigate, clarify and protect people from dangerous tricks of people holding high positions and positions, holding great power.

The Mars expedition can last at least 3 years. Brain structure effect The missions that bring humans to Mars are considered to be a major leap in space exploration. NASA has a goal of sending people to Mars by 2030. However, a trip to Mars is not the same as taking a flight to New York. Because space is an extremely harsh environment for human life, including the lack of gravity and harmful radiation, as well as isolation and lack of day or night. Missions to Mars will require more astronauts physically and mentally than man-made journeys in 60 years of space exploration. A flight to Mars and back will take about 14 months. Meanwhile, the actual exploration mission will last at least 3 years. Maintaining good cognition and effective teamwork are the prerequisites for the safe and successful outcomes of these tasks. However, a new study published in the journal Frontiers of Physiology found that the lack of gravity during such missions can have negative effects on cognitive skills, as well as emotions. of the astronauts. Since the first space missions, it is clear that exposure to a “microgravity” (weightless) environment leads to drastic changes in the human body. This includes changes in the cardiovascular, skeletal and nervous systems. On Earth, we discover gravity with the aid of our eyesight and various organs, including those in the inner ear. When our heads are upright, the hearing stones in the vestibular system are perfectly balanced by a viscous liquid. However, as we move the head, gravity causes the liquid to move with it. This activates signals to the brain that our heads have changed positions. In space, this process is no longer active. Space flight can even bring about adverse changes to the brain structure of astronauts. Changes in brain structure were observed in astronauts after they returned from the International Space Station (ISS). The scientists found that in these astronauts, the brain physically moves inside the skull and reduces the ability to connect between regions of the brain layer, the cortex and the inner regions. Emotional perception is extremely important to astronauts. Difficulty recognizing other people’s feelings The acumen and quick thinking of astronauts are essential elements in a space mission. So is the ability to accurately “read” each other’s emotional expressions. Because, they have to spend a lot of time sitting together in a small space. Therefore, it is recommended that space agencies consider training, as well as psychological support for astronauts before the flight, to minimize this risk. To date, how these changes affect behavior is not concretely understood. However, scientists are getting closer to the answer. Because, they realize, astronauts can be disoriented, disturbed perception, balance disorders and motion sickness. However, such findings are often made based on a small group of people. New NASA-backed research has explored the effect of microgravity on cognitive performance. However, 24 study participants were not sent to space. Instead, the scientists asked these people to lie in bed. This is because the effect of a certain type of bed rest is similar to that of microgravity. Therefore, scientists have repeatedly applied this method in research. When we are upright, the body and hearing stones in the vestibular system are in the same direction as gravity. Meanwhile, the moment of lying down, the body and hearing stones are perpendicular to each other. Therefore, study participants had to lie on their back at an angle of 6 degrees, their head lower than their body. They were asked not to change their position for almost two months. At the same time, the participants also routinely perform a series of cognitive missions designed for astronauts and related to space flight. As a result, it helps to evaluate their spatial orientation, memory, risk-taking behavior and understanding of their feelings about others. The results showed that the cognitive speed of these people slowed a bit but remained reliable in tasks related to sensory and motor skills. This seems to be consistent with reported changes in brain tissue density across “motor sensory regions”. These are the main motor and sensory regions of the brain, helping to process sensory input and movement, observed after a person has flown into space. Participants also had difficulty recognizing emotions when looking at people’s faces. Adjusting to changes in gravity takes time and effort. While performance on most cognitive tasks initially decreased, after about 60 days, the participants remained unchanged throughout the test. However, their ability to perceive emotions continued to deteriorate. In fact, the participants became inclined toward negative emotions. They are more likely to recognize another person’s expression as angry and have a hard time explaining how happy or normal the other person is.

The thing to do in digital transformation is to formulate quantitative indicators to convert to “digital thinking” … Only then, new decisions will be highly effective and there is no room for friendship to dominate. Building a digital nation and developing a digital economy is placed as a focus in Document of the 13th Party Congress to motivate Vietnam to become a high-income developed country. This issue was also heatedly discussed in the first few days of the Congress. This is a very right development path choice in the current political, economic and social situation in the world and in the region. From the development experience of several decades, the world has realized that only high quality human resources associated with high technology can create high performance for development to rise ahead of the future. Only high quality human resources associated with high technology can create high efficiency The question “what will be after industry?” has been in place since the industrialization process created a group of 7 developed industrialized countries. About five or seven years ago, public opinion was noisy about the term 4.0 technology according to the German calling given on the World Economic Forum. After a while, people discussed the content of “generation 4.0” including “artificial intelligence” (AI) and “Internet of things connecting things” (IoT). In recent years, development has turned to digital economy, digital technology, digital nation … Three books and 3 heads of state The first person to talk about technology as the driving force behind human development was Alvin Toffler, an American sociologist. He spent 30 years (1960 – 1990) researching, generalizing, drawing rules and forecasting development with three world-famous books: Future Shock (1970), Third Wave (1980). ) and power ups and downs (1990). The content of all 3 books is just to point out that: Humans started with the era of agriculture; mechanical technology made machines replace manual labor to create the industrial era; Next, information technology has created machines to replace human intellectual labor to create the information age. The information age is the third wave after agriculture, then industry, making human beings have to make fundamental changes like a great shock in the future to develop. For each of these epochs there is a different form of power: Force is the form of power in the agricultural and financial era in the industrial age and intelligence in the information age. These three books have attracted great attention to the heads of many countries, especially Zhao Ziyang (then Prime Minister of China), Lee Kuan Yew (Prime Minister of Singapore) and Kim Dae Jung (President of Korea). ). These three heads of state invited Alvin Toffler for private talks. All three countries have now become newly industrialized countries, are in the top group of the world in terms of digital nation construction and digital economic development from being an outdated agricultural country in the 1960s. I have 8 years of collaborative scientific research in Poland (1980 – 1988), so I have access to 3 books by Alvin Toffler quite early. Since then, after returning home, I have decided to carry out “digital reform” in the field of geographic information production in our country. Completion of digital technology transformation since 2000 In 1989, I introduced satellite positioning (GPS) technology to ground measurement after US President Bill Clinton issued a decision to allow the use of GPS for military purposes only. . At that time, our country was still being embargoed, having difficulty in accessing technology on all sides. Today, GPS is so universal that it’s attached to every smart device to locate every activity. From the success in the reform of geolocation technology, to the year 2000 I completed the conversion of all terrestrial imaging equipment from airplanes, satellites; ground measuring equipment; digital data processing equipment. By 2010, all geographic data of Vietnam have been established in the form of digital information. I have been conferred the title of Labor Hero by the State President in the Doi Moi period for this achievement. A few weeks ago, a friend working at the Department of Geodesy, Maps and Geographic Information told me that his superiors had come down to the Department to work on digital transformation. The director replied that the digital transformation here has been completed since 2000. The work ends soon. Listen to stories, I am also happy From qualitative to quantitative Looking back at the experience of digital development in the world and ourselves, it can be seen that artificial intelligence is playing the role of a machine replacing human intellectual labor, making an important breakthrough for development. Associated with artificial intelligence, all information must be in digital form. Human intelligence is biased towards qualitative thinking, often dominated by love or hate, which loses its honesty and objectivity. All judgments and judgments often lack scientific quantitative basis, many cases lead to wrong decisions. On the other hand, artificial intelligence thinks quantitatively, every decision made is sufficiently valid after analyzing the data. Wrong decisions can only happen when the data is wrong. Currently, the world has launched a huge system of indicators to evaluate every process, every industry, every activity, every country. Every year, the World Bank publishes a document called “World Index” with millions of indexes to evaluate thousands of fields of hundreds of countries. Such indicators are a valid basis for each country to evaluate themselves at what level in each field, and then make appropriate adjustment decisions. This is the essence of “digital thinking”. Human thinking must also change from qualitative to quantitative. That is the digital transformation of thinking. Our country currently lacks the system of indicators necessary to evaluate and decide. Everything is still in a state of qualitative thinking. The thing to do in digital transformation is to form quantitative indicators to convert thinking into “digital thinking” as a habit in development until it becomes “digital culture”. Only then can decisions be highly effective and there is no room for friendship to dominate.

Researchers have gathered tissue samples from patients for brain research after death. Accordingly, the “zombie” gene may influence the study of brain-related diseases if the team prolongs the time to access the sample. The researchers analyzed gene expression from living brain tissue and found that in some cells, gene expression increased after death. They observed that inflamed glial cells develop and grow arm-like branches several hours after death. “Most research confirms that all activity in the brain stops when the heart stops beating, but not really,” said Dr. Jeffrey Loeb, Dean of the Department of Neurology and Rehabilitation at the University of Illinois Medical School. , Chicago. The “zombie” genes are activated after the brain stops working. They are glial genes responsible for attention to damaged brain tissue. Photo: Dr. Jeffrey Loeb / UIC. According to the Yourgenome.com Gene expression is the process of converting genetic information in DNA into functional products such as proteins or other molecules. “It’s not surprising that glial cells develop right after the heart stops beating. These cells become inflamed and their job is to clear things up after brain damage such as hypoxia or a sudden attack. Stroke, “Loeb said in a university press release. Also according to him, the connections are very remarkable. Most research uses post-mortem human brain tissue to find treatments for disorders like Autism, Schizophrenia, and Alzheimer’s disease. However, these studies did not take into account continuation of gene expression or cell activity. “Our findings will shed light on research on brain tissue in humans. It’s just that at this point, we haven’t yet quantified the changes,” said Loeb. Loeb is the director of UI NeuroRepository (at the University of Illinois), a bank that stores brain tissue, with consent, of patients with neurological disorders. Brain tissue is collected and stored when the patient dies or is in surgery. Not all brain tissue is needed to diagnose the disease, some of which is used for research. Loeb and his team noticed that the gene expression patterns in living brain tissue did not match any previous findings of brain tissue gene expression after death. Therefore, they conducted a simulation experiment to observe the expression of all genes in the human body 24 hours after death. As a result, about 80% of the genes maintain relative stability within 24 hours. These include genes that provide basic functions of the cell. Another group of genes, brain activity (such as memory, thinking, and seizure) quickly subsides within hours of death. A third group of genes – the “zombie” gene – became more active while the other groups of genes gradually decreased activity. During the first 12 hours of brain death, activity of the “zombie” gene peaked. “We found 1,427 genes clustered. A cluster of 317 rapidly depleted genes was predicted to be neuron and coincided with genes dependent on activity. The second cluster of 474 genes is predicted to be glia, consisting of astrocytes and microglia. Notably, due to the rapid decrease in the cluster of nerve cells, the glial cell cluster has significantly increased “, the scientists shared. These findings mean that researchers need to take these changes into account and minimize the time from death to study as much as possible to curb those changes that are too big, Dr. Loeb said. “The good news is that we know which genes and cells are stable, are decreasing, and which are increasing over time, which helps guide post-death brain research better,” he said. Therefore, naming the genes that are most active in the brain after death as “zombies” only makes this research more remarkable. This has nothing to do with the zombies in the sci-fi movies. Understanding the brain’s chemical signals is key to helping scientists find ways to cure brain-damaging diseases like Huntington’s chorea. This research was supported by an abundance of resources from the University of Illinois neuroscience archive, a collection of brain tissue samples with epilepsy and other ailments.

Smart bowl helps users to lose weight. IGGI is made from Stoneware, a clay-based ceramic material that contains a small amount of stone, has a design “hidden calories” to trick the brain, helping to eat less than normal. The curved bottom of the bowl makes it always look full, and actually contains up to 33% less food, no more than 600 calories. And yet, the red heart of the IGGI bowl helps people to have positive feelings, reducing appetite compared to white dishes. In particular, it also helps users to enjoy more beneficial dishes, especially green vegetables. According to Roderic Andrews, combining red with the IGGI application, the two create a more “balanced” eating habit. Each IGGI bowl has 15 recipe cards and 15 habit cards that encourage users to maintain healthy nutritional habits, persevere in the pursuit of a chosen scientific diet, eat less, but still feel full. Stoneware material is Japanese-inspired, creating for the bowl of beauty luxurious, microwave-friendly and easy to wash after eating. Ngoc Anh ( YDC– 3/2021 )

In addition to a number of corporations such as Samsung Electronics, LG Electronics of South Korea and Huawei of China, most recently, Apple (the US technology corporation) also announced to recruit engineers to participate in research and development. to develop wireless technology next generation 5G. According to current research directions, the theoretical speed of 6G network will be one Tb / s, about 100 times higher than the theoretical speed of the 5G network (10 Gb / s). The new technology will also have broad coverage and be more energy efficient than the previous generation. Most importantly, 6G hopes to solve the limitations of current 5G networks. Specifically, even though it is considered as an Internet of Things (IoT) network, 5G still has a long way to go to achieve universal universality due to its limited ability to transmit signals at a height of many thousand meters. ground or deep below the ground or seabed. Meanwhile, 6G is research-oriented to meet both intelligent connectivity, deep connection, heterogeneous connection and everywhere. On the other hand, although 5G network has helped people make good use of artificial intelligence (AI) technology to optimize, distribute resources and process data, the forecast 6G network can do better by making AI becomes intelligent with the processing speed close to the human brain. 6G will integrate the new physical, digital, and services worlds to deliver stricter network performance metrics (KPIs) than 5G. However, the development of 6G networks is still just beginning and the end result will depend on speed of deployment and consensus on the technologies to deliver the ultimate standard. Experts say that the next 10 years will be a period for research and 6G will start to be commercialized from 2030. In the process of deploying previous generations of mobile networks such as 2G, 3G or 4G, Vietnam often lags behind the world. As for 5G networks, we are now starting to perform tests with the expectation of entering the first groups of countries to deploy the technology. But according to experts, in fact, Vietnam is still quite far away from the world in terms of research capacity and deployment methods in the telecommunications sector. Therefore, even though all countries have the same opportunity in terms of time to lead the research and deployment of 6G networks, not all countries have enough potential in science, technology as well as finance. join the race for core technology of 6G right now. Instead of racing to research core technologies, we should take advantage of other existing strengths to catch this wave, such as: Focusing on research and production of terminals for 6G; researching in-depth in the control and optimization of the 6G network system; research on AI technology for management system, data processing in 6G network system; blockchain security research (blockchain) … to solve the safety problem in the new network system. This may be a medium and viable market for Vietnam in the future.

Light-colored furniture may look beautiful and luxurious, but it feels like being in a showroom, making visitors feel unnatural by feeling the need to keep everything clean. “If the host often feels clean and tries to keep it clean, it can be stressful for the guests. They really want to be comfortable but they are afraid of creating stains or leaving stains on the interior, ”says psychotherapist Cullins. 2. Insufficient lighting Insufficient light in rooms can cause inconvenience in living and create feelings of sadness and depression. While rooms with too much light can interfere with sleep and relaxation. It is important to consider the function of each room in the house and adjust the light level to suit the intended use. Psychotherapist Cecille Ahrens says that using neutral tones and sunlight can help relax and increase concentration. According to studies on psychology and color correlation, white and green light is believed to help treat depression. 3. Mixed sound Noise is one of the most common stressors and comes in many forms, including TV sounds and conversations in the home. One advice from psychotherapist Mark Loewen is that, if the TV makes you feel stressed, switch to soothing music to relax. 4. TV screen Ahrens says watching too much TV can be stressful, especially if it happens a lot in one space. 5. The living room was cluttered “A cluttered and disorganized space can cause mental turmoil, making us feel uncomfortable and stressful,” says Cullins. Getting tangled or tangled in the wires of the TV and radio speakers can also cause visual discomfort for some people. That clutter gives our brains more intuitive information to process, which in turn makes it impossible for the brain to relax. 6. Old stuff Old, outdated furniture can make your mood worse. “If the sofa in your living room is old, dirty or outdated, you may not feel comfortable in the space,” says Ahrens. 7. Working in living room Work and rest should not coexist in the same space. However, in the past 2020, it is difficult for many people to separate work from their personal lives. That has made the job not as effective as expected. “By separating the workspace from the relaxation space, you create not only physical separation, but also mental separation,” says psychotherapist Ariel Sank, a psychotherapist. While this can be difficult living in a small space, simply changing the desk position and orientation can be of great help. Dieu Linh (According to Insider)

Weight loss menu for office workers is very important and it determines up to 70% in physique improvement. (Photo: Depositphotos)

According to Ms. Kalen, the menu should include a green vegetable salad, be it cabbage, scallions, dill, as well as cheese or feta cheese. These foods are rich in fiber, iron and antioxidants, which have a beneficial effect on the functioning of the digestive tract and speed up the metabolism.

In addition, steamed turkey cutlets are also recommended for office workers. Onions, parsley or chili peppers can be added with 500 grams of meat.

“Unlike chicken, turkey has more protein and less fat. They help satisfy hunger for quite a long time. Turkey contains vitamins B, potassium, zinc, selenium, niacin and thiamin, which help protect the body from oxidative stress and affect the metabolic rate, ”said Russian nutritionist on Instagram.

Also, whole grain breads with roasted chicken, butter, natural yogurt, and lettuce are also recommended. Bread contains gut-healthy fiber, avocado helps to satisfy hunger in the long run and promotes weight loss due to its high content of omega-3 fatty acids, vitamins and minerals.

A smoothie made from whole-grain oatmeal, banana and natural yogurt will restore the gut microflora, Ms. Kalen added; Celery salad with eggs and fennel will saturate the body with fiber as well as essential amino acids, while also helping to remove excess fluids from the body.

4 effects of white radish on human health:

1. Reducing bad cholesterol: According to a scientific study, adding more radish in the diet will significantly reduce serum cholesterol and triglyceride levels, significantly increase HDL cholesterol (good cholesterol).

2. Helps relieve pain effectively: The spicy substance in radish has antibacterial properties, significantly reduces pain, strengthens the immune system, especially children.

3. Help the liver to function well: Radish contains betaine bioactive, supporting healthy liver function.

4. Good for the brain: A study at Wake Forest University has shown that high levels of nitrates in radish can increase blood flow to the brain, enhancing brain health. Especially effective for developing intelligence of children.

How to perform wall legs up

Just lie on the bed or gym mat against the wall. Using the arm as a support, put the foot on the wall. Try to keep your butt as close to the wall as possible. Adjust your posture so that your feet are firmly pressed against the wall, your body is perpendicular to the wall. Your hands can be placed under your torso or put your hands on your stomach or in a position that helps you feel most comfortable.

You can put a thin pillow under your butt to help correct posture.

Hold for 5-10 minutes for each exercise. Can practice many times a day.

The benefits of wall legs up

Small thighs and tighten round 3

When doing this, your legs will have to be straight up against the wall. This forces us to tighten the muscles in the calves and inner thighs. As such it also has the effect of burning more fat, toning muscles, supporting weight loss.

Relax your calf muscles

The stretching state helps the calves relax and relax better.

Bringing blood to the brain, dispel fatigue

This position helps the blood pump to the brain more efficiently. Poor blood to the brain will affect intelligence and ability to work. Therefore, we need to perform movements that help promote pumping blood to the brain, ensuring the functioning of the nervous system.

Moderating anger

When doing the footrest against the wall, focus on taking deep, regular breaths. It acts as a meditation, helping to curb anger. You will regain your calm in a simple and effective way. So, when you need to control your emotions, you can do wall legs up.

In a report to the Ministry of Health, Bach Mai Hospital said that from February 1, 2020, the number of employees and job transfer to other agencies at Bach Mai Hospital was 221 people. Prof. Dr. Nguyen Quang Tuan, Director of Bach Mai Hospital confirmed that many of the hospital’s human resources have recently quit their jobs and moved to other places. Among those taking leave, some have the title of Associate Professor and Doctor, but the leave is to move to another place with higher income. In addition, human resources quit due to the reorganization of payroll and employment positions due to complete financial autonomy in the hospital.

The hospital report also said that during this period, the hospital recruited and signed contracts with 506 people, including: 199 people who are officials, employees, and workers with professional qualifications; 232 nurses, medical technicians have completed training courses to improve skills organized by the hospital in 2019 and 75 working positions to welcome, guide and transport patients …

So is there a situation of “brain drain” at Bach Mai Hospital as public opinion raises? Talking with reporters, some doctors and staff shared about the reasons why they quit their jobs at Bach Mai Hospital, and also shared their sadness and concerns when they had been with the hospital for many years.

Working in the Department of Oncology of Bach Mai Hospital since the days of university graduation until the retirement age, Dr. LVT is one of 222 staff members and staff who just resigned. Without stating the reason for taking leave, Dr. T asserted that not only him but also many doctors and staff had feelings of “sadness and concern.”

“I am very sad when I have to move to the hospital even though I am going to the retirement age and have to move to the hospital for many years,” said Mr. T.

Many other staff members resigned at Bach Mai Hospital also expressed their regret. However, when asked about the reason why they decided to quit their job at a large hospital like Bach Mai, many people said that it was a personal reason. Some even refused to answer because they quit their jobs and were no longer members of this hospital.

Quitting his job at Bach Mai Hospital from March 2021, Mr. NNK, an employee of the Faculty of Pharmacy shared, he sent his leave to his leaders right after Tet for many reasons, of which the main reason was due to the mechanism of The hospital has a change: “This change makes medical staff like us have to work more and more pressure, but the total income not only does not increase but also decrease than before”.

Answering VOV.VN’s reporter, Dr. Do Van Thanh, Head of Personnel and Organization Department, Bach Mai Hospital, it is normal for employees to quit their jobs, taking place every year. However, the past year at Bach Mai hospital is clearly higher.
