Accordingly, US investors have made a profit of up to $ 4.1 billion by investing in this world’s number 1 “virtual currency”. Right behind the US is China with 1.1 billion USD. The remaining positions in the top 5 include Japan ($0.9 billion), UK ($0.8 billion) and Russia ($0.6 billion). Notably, this list also includes the presence of Vietnam. According to Chainalysis estimates, Vietnamese investors have earned $0.4 billion in 2020 by investing in Bitcoin. On a global scale, Vietnam ranks 13th in the world in terms of Bitcoin-related profitability. Vietnam is also the 4th country in terms of cryptocurrency profits, just behind China, Japan, and South Korea. Ranking of the 25 most profitable countries from Bitcoin in 2020. According to Chainalysis, due to the decentralized nature of the technology, it is very difficult to find out where the parties are in a cryptocurrency transaction. The published results were estimated using transaction data from services that Chainalysis tracks. In its analysis, Chainalysis measures the total volume of Bitcoin transactions at each crypto exchange. They estimate the amount earned by the difference in the price of Bitcoin at 2 times of entering and leaving the exchange. Chainalysis then distributes this profit based on each country’s share of web traffic on each exchange. By doing this, Chainalysis has produced a report on how much return investors in each country will make with Bitcoin in 2020. Even so, Chainalysis’s methodology is approximate and not yet available. regardless of the profits from the digital assets still in the exchanges. Vietnam currently ranks 10th on the Global Cryptocurrency Acceptance Index. According to Chainalysis, Vietnam is a perfect example of a country where the level of participation in cryptocurrency transactions far exceeds the ranking of the economy. Although only ranked 53rd in GDP with about $262 billion and ranked as a low-middle-income country, Vietnam still has a fairly high level of acceptance for cryptocurrency transactions. Accordingly, Vietnam ranks 10th out of 154 countries in the Global Cryptocurrency Acceptance Index. This is one of the rare indexes where Vietnam has the same rank as developed countries such as the US, China or South Africa, even more than many other developed countries such as the UK, France, Germany, and Spain. , Japan, Korea,… With such popularity, Chainalysis is not surprised that Vietnamese investors ranked 13th in the world in terms of income earned from Bitcoin in 2020. Many Vietnamese Bitcoin investors have won big in 2020. Similar to Vietnam, this phenomenon also occurs in a number of other countries such as the Czech Republic (54th in GDP, 18th in income from Bitcoin), Turkey (25th in GDP, 16th in revenue). Bitcoin income) and Spain (19th in GDP, 9th in Bitcoin income). On the other hand, despite having the 4th largest economy with the 2nd largest population in the world, India is being left behind in the crypto economy. In 2020, the country’s investors only made 241 million USD from the increase in the price of Bitcoin, ranked 18th in the world. This is because the Indian government does not seem to be very friendly with cryptocurrencies. India used to ban all cryptocurrency transactions in the country, until the Supreme Court of India lifted the ban in March 2020. Although many Vietnamese investors are making big profits from cryptocurrencies. Having said that, investing in Bitcoin or other cryptocurrencies is a very risky investment. Therefore, investors need to be careful and learn carefully before deciding to enter this harsh market.

Born… as a historical necessity To learn more about one of the oldest and largest railway systems in the world, RFI Interviewed engineer Ta Quang Anh, working at the French National Railway Corporation (SNCF) about the birth of the French railway network. The engineer said that the French railway industry was “conceived” in the first three decades of the nineteenth century. Appearing more slowly in England, where the first steam engine was mounted on railcarts in trade fairs from about the mid-1810s, the birth of the French railway network was also in the similar scene, as a historical necessity. That necessary background is the final stage of the First Industrial Revolution in Europe, the period of the meeting between supply and demand. Regarding demand, in the economic field, it is the need to transport finished products in large quantities, especially in the mining industry and later in chemicals, textiles, and agriculture. In the political field, it is the need to plan territory, unify transportation and administration in a large country with many diverse geographical and cultural characteristics. The achievements of metallurgical technology have enabled the production of quality steels for train wheels and tracks, especially with production capacity for thousands of kilometers of track. In terms of supply, it’s the ability to respond to technology. This is also the intersection of two technological factors that have both developed to the necessary maturity at that time. On the one hand, the achievement of metallurgical technology has allowed the production of quality steels for train wheels and tracks, especially with production capacity for thousands of kilometers of track. On the other hand, in the mechanical and steam engine industry, the soul of the industrial revolution, despite overcoming barriers to liberate labor, is still an inspiring creative ground for optimization in terms of technology. performance and size. On the French side, in 1823, the first railway, 18 km long, connected a coal mine from the vicinity of Saint-Etienne down to a port of the Loire in Andrézieux. Although only using gravity to transport coal to the river port and using horse power to pull construction materials in the opposite direction, in terms of infrastructure, this is considered the first line of the French and European railway network. continent. Only 7 years later, another 58 km line connecting Saint-Etienne with Lyon was also put into operation. This was the first time in France, the steam locomotive improved by French engineer Marc Seguin was put into use instead of horses with a record speed of 12 km/h at that time. A year later, in 1831, the line also began carrying passengers. In 1823, the first railway, 18 km long, connected a coal mine from the vicinity of Saint-Etienne down to a port of the Loire in Andrézieux. In 1814, at the very beginning of the world’s railway history, when it first appeared in England, a strategic report was submitted to Emperor Napoleon by Chief Engineer Moisson-Desroches, highlighting the importance of it. of planning a railway network of seven lines radiating from Paris to all parts of the “hexagonal country”. By 1837, the strategic idea of ​​Moisson-Desroches was concretized in the planning of Alexis Legrand, then the General Architect of roads and mines of France. The drawing that later became known as the “Legrand Star” was the first planning map of the French railway industry. Also in 1837, the first dedicated passenger railway was put into operation, connecting Paris to the suburb of Saint-Germain-en-Laye. On paper and in the field, 1837 can thus be considered the “AD” year of the French railway history. Before World War I, nearly 60,000 km of Line 1 covered France, a sixfold increase in about 60 years. After about 15 years of relatively spontaneous development (since the railway law 1842 stipulates the model of railway socialization), by the end of 1858-early 1859, the railway agreement between the State and 6 railway companies was established. iron is an important legal corridor for network development. This agreement is meant to divide the development market share of private companies authorized by the State to develop the arterial railway system. In 1865, the law was expanded to allow local governments to be authorized to build and operate branch and cross lines for railway companies. The period of the second half of the nineteenth century and the early years of the twentieth century, with the development stimulus mechanisms of the central and local governments, was the period of breakthrough development of the French railway network, at least in terms of total length of routes in the whole system. By the time of World War I, nearly 60,000 km of Line 1 (now about 30,000 km) covered France, a sixfold increase in about 60 years. All provincial administrative sub-areas are connected to the railway network. Also during the early twentieth century, power options such as electric and diesel were also tested and developed for locomotives. The birth of the SNCF was the result of the nationalization of the railway industry in favor of the plan to electrify the entire railway network, a proactive step after the energy and economic crisis of the 1930s. In 1938, the National Railway Corporation (SNCF) was established. The entire 42,700 km of railway with debts and more than half a million railway employees are combined into one. The birth of the SNCF was the result of the nationalization of the railway industry in favor of the plan to electrify the entire railway network, a proactive step after the energy and economic crisis of the 1930s. This was considered the optimal political-economic choice at that time, in the context that the precursor private companies of SNCF faced a lot of financial difficulties after a period of overheating development in terms of terminal infrastructure. In the nineteenth century and especially after the years of World War I there was no source of income, which was followed by the Great Depression of 1929. Railway unions, representing more than half a million workers, became industrial unions are very vocal in society, contributing significantly to workers’ movements. A breakthrough in quality The operating speed at that time was 260km/h, in the same year, the design and test speed reached a world record at 380km/h. The birth of the TGV opens a new breakthrough development phase for the French railway industry. Unlike the breakthrough period in infrastructure in the second half of the 19th century, TGV has “miniatured” France and even Europe with only 3-4 hours of travel. During the period 1990-2010, many domestic TGV routes were inaugurated, notably the Eurostar route running through 50 km of the English Channel tunnel to the UK, the Thalys route going to Belgium and the Netherlands… In 1997, the State separated the infrastructure management part from the SNCF by establishing the National Railway Network (RFF). This is the first step of France when implementing commitments on competition in the field of rail transport in the European Union (EU). In 2015, RFF re-entered a member company of SNCF, after having spun off the mining part into another independent subsidiary in the group. In 1981, France put into operation the first high-speed train line TGV connecting Paris and Lyon. In 2007, France once again broke the world record for the test speed of the express train at 574.8 km/h. To date, this is still the world record for train technology running on rails. In 2020, the state monopoly on train operation officially ends. During the last 30 years of the twentieth century, the absolutely safe operation of 400 tons of steel on rails at 320 km/h has always been a technological icon in the ground passenger transport industry. TGV technology is exported and transferred to many countries, in Europe, to the US, Morocco and even Korea. For the French, TGV is a “national pride”. According to a poll of the French population, the TGV is considered one of the most important inventions of the 20th century, along with the computer, mobile phone and microwave oven. For the passenger railway industry, TGV was born as a lifeline in the context of the energy crisis of the 1970s, the aging of the traditional railway system from nearly 150 years made the railway no longer an option. number one choice for travel needs as highways thrive and air routes become increasingly accessible to price segments. In passenger transport, the decisive factor is not necessarily the speed of travel, but the sum of travel time, comfort, safety and, of course, price. TGV was born to most harmoniously meet these factors. TGV routes connect the centers of major cities (in France and later in Europe, both mainland and British islands) in the journey with moderate time, high safety, good service quality. The railway network in France is operated by the French National Railways Corporation (SNCF). For those doing railway engineering and technology, TGV’s 20 years of conception, 40 years of exploitation, perfection and development has been and will be an inspiration for technical innovation initiatives in many years. fields, from structural infrastructure, energy, signal information to rolling stock; from the construction and manufacturing industry to the maintenance industry. According to engineer Ta Quang Anh, the nearly 200-year history of formation and development is an advantage of French railways. In the world, besides the UK, there is no country as “rail age” as France. This is a great advantage in terms of experience. The coverage of the French railway network compared to the entire geographical territory is very high. Although France is not a country with a very high percentage of urban population, according to one statistic, about 89% of the French population live less than 10 km from a train station (in cities like Paris, this distance is much smaller). . This contributes significantly to the formation of habits and the need to use railways for transportation. About 89% of the French population lives less than 10 km from the station (in cities like Paris, this distance is much smaller). This contributes significantly to the formation of habits and the need to use railways for transportation. On the other hand, rail transport in France with over 80% electrification is a fundamentally environmentally friendly transport industry. With such a large coverage, in the medium and long term future, with the commitments of the French Government to reduce greenhouse gas emissions in the framework of global environmental agreements, railway transport (both cargo and passengers) will undoubtedly remain key government priorities. As more than 80% of the railway network is electrified, with France’s civil nuclear power capacity, the French railway industry has a huge advantage in terms of energy initiative over most railway countries. However, the French railway industry also faces some limitations. A prime example is the British railway industry, which has been in decline since the late twentieth century. In the case of the French railway industry, in terms of people, changing production habits is no longer suitable for the application of modern means and production methods, in many cases, encountering resistance from the government itself. old experiences. In terms of infrastructure, most of the French railway network was designed and built before the twentieth century. Adapting to climate change is a big challenge for network maintenance and repair. TGV is a legacy engineering innovation based on ballast rock infrastructure and wheel-rail contact. But if you want to increase the speed of operation to over 400 km/h, such infrastructure is likely no longer suitable, especially when put on the balance sheet with the cost of maintenance. Of course, train speed is not a prerequisite, but if France decides to race in this direction, it must accept going slower than other countries that have developed or transferred technology for maglev infrastructure. such as Germany, Japan, China.

Irish people often tell each other stories about giants who were able to create an island just by taking a handful of sand and throwing it out into the sea. Professor Márta Korbonits said that such old stories have some historical basis. And hard to believe, scientists have found what they’ve been looking for all along. As it turns out, there are many Irish people with the AIP gene mutation. These mutations are responsible for the excessive height in some people. In the UK, these mutations are very rare (probability about 1 in 2000 people), and in Mid Ulster – Northern Ireland, these mutations are becoming more common (1 in 150). One of the most famous giants in Ireland was Charles Byrne (1761-1783) when he was 2.2m tall. According to legend, giants are extremely powerful, but in reality, they are not. They often suffer from heart problems, eye problems, and joint pain. Without proper treatment, most of these giants die before the age of 30. 2. Werewolves There are very few origins of werewolf legends because their lives are always associated with the forest. However, people have found archaeological ruins and cave paintings of the combination of people and things from ancient times. At that time, people always wanted to become stronger. So, they chose for themselves a summoned beast and took this form. To go to the battlefield, the warriors choose a powerful summoned beast that is the wolf. Before fighting, they will drink magic potion that affects the nervous system making them think they are invincible wolves. In addition, belief in the existence of werewolves is supported by the genetic condition hypertonia. It is an abnormal amount of hair growth on the body and face, also known as werewolf syndrome. It was not until 1963 that Dr. Lee Illis gave the name of this disease. Another psychological disorder is called Lycanthropy. This is a delusion that makes the patient think that he can transform into a species between man and animal. It is also believed that this disorder becomes stronger during the different lunar phases. 3. Vampires Porphyria is a rare genetic disorder (1 in 200,000 people). If either parent has the condition, their child has a 25% chance of having it. This disease causes a pigment imbalance, and hemoglobin begins to decay by ultraviolet light. People with this disease are greatly affected by sunlight. So the only time they can go out is at night. In more severe cases, the patient’s tendon is deformed, causing the fingers to constrict. The skin around the lips and gums becomes dry, the front teeth protrude and turn red. So they will look like vampires. In the Middle Ages, people with porphyria were burned by the judgment of the Inquisition. 4. Dragons Theory of a connection between dinosaur bones and dragons began in Mongolia. Here, the word “dragon” is found associated with different geographical names. This is because, in some areas of the Gobi desert, anyone can find dinosaur bones because they lie completely on the surface of the Earth. These skeletons are still abundant in this place causing many illegal excavations to take place. It is an important fact that there are no myths of this kind in Africa because there is no access to dinosaur remnants there. But why do we picture dragons like reptiles with claws and scales? This is explained by the way we see things around us. Their skeletons resembled the bones of modern lizards, snakes, and crocodiles. If you zoom in a few times these animals, they will look like dragons. Also added that lizards and snakes sometimes have two heads, like some dragons in fantasy or legend.

In addition to the shows that have great significance for the fashion career, making the names of the designers, many shows have had conflicting opinions with the image of models wearing overly sexy, tight-fitting outfits. offensive. On the evening of March 31, the Mugler brand released a fashion film to introduce the Spring-Summer 2021 collection with inspiration on the sexy beauty of modern women. All designs are hugging the wearer’s body with attractive cuts. Notably, participating in the show, supermodels Bella Hadid and Irina Shayk when topless and wearing bold outfits. Bella Hadid attracted attention when wearing a topless outfit at the Mugler show. Many viewers appreciated this outfit, helping the model show off her body, highlighting the seductive features. The rest have contradictory opinions when they think that the trend of wearing this outfit is quite offensive and less subtle. An account left a comment: “I hope fashion followers do not choose this product or promote the trend of wearing underwear. The outfit is designed like wearing only underwear that makes me feel offensive. when standing in front of the opposite person “. Before that, there were many fashion shows that were also controversial when the model was sexy, too revealing. So what is the limit to glamor at shows? Topless model On September 22, 2019, the show introducing Gucci’s Spring – Summer 2020 collection took place at Milan Fashion Week (Italy). The majority of female models in this collection (BST) do not wear underwear, revealing the entire bust in front of the camera. July 2019 is the time of Haute Couture fashion week. Attending this event, Schiaparelli’s creative director – Daniel Roseberry brought 30 unique designs, helping women to easily show off their hot body. Many designs are sewn with a penetrating fabric to reveal the model’s bust and a sparkling scarf wrapped around her neck. In the fall of 2019, Giorgio Armani organized two showcases for the Armani Prive Couture Fall 2019 luxury collection. At first there was the participation of fashion editors, the second show for celebrities. In 82 unique works, many designs attract attention because they are made on a transparent fabric background, completely exposing the topless model of the model. Many fashion shows have female models to show topless. What limit for sex appeal? According to the Elle Vietnam , the sexiness in fashion is often equated with bad feelings. However, most women desire to be appreciated and gradually want to express themselves to those around them. But how to show it is a different story. “Sexy woman” is a broad topic with many different opinions and points of view. Mr. Anthony Vaccarello, who succeeds the creative director position of Slimane Saint Laurent once said that he was attracted by the fashion heritage of the company in the 1960s and the revolutionary trends of the 1970s when women. Immerse yourself in sensual designs. Vanessa Friedman – Fashion Director, New York Times critic asserted: “Making the most of the materials that penetrate and show more of the curves of the legs or cleavage is inspired by the 20th century fashion revolution It will be difficult for women to change their fashion mindset, however, the flow of fashion can lead the way for women to confidently express themselves more. In the commentary on Saint Laurent’s Spring – Summer 2019 collection for the magazine Vogue, critic Sarah Mower said: “The point here is whether or not you want to pursue the style that the innovative Vaccarello is for women, you should respect those who love fashion thinking. there”. When feminism took the throne, people took a different view of “sensual” that it was “self-reliant” instead of words like “lack of cloth”, “offensive” or “improper”. However, the limit between “offensive” and “sexy” has never been as fragile and difficult to say as it is today. Same outfit but completely different look if two models have different poses. According to the Elle Showing sexy beauty is the right of every woman. However, the female model’s public performance needs to keep the standards of the sexiness on the body and in each outfit. According to Elle Vietnam, sexy fashion is often equated with negative feelings.

It is known that the ‘O-tower’ will be the venue for OPPO’s large-scale programs, a lush urban landscape in the middle of the city. This design is inspired by the letter O and fingerprints, when combined, it will produce an extremely unique and novel shape. The design company is the Bjarke ingels group (BIG), the building designed to reduce energy consumption and demonstrate OPPO’s commitment to endless innovation by connecting ‘ground and sky’ in a unified ring. cooperation continuously. BIG started working with OPPO in early 2019 to develop the design for the R&D headquarters and the overall plan for the site. It will be located along the main access road of the city, between a natural lake, the urban center, and a 10,000 square meter park. With this prime location, BIG and OPPO want the O-tower as a new symbol and gateway to the future science and technology city of Hangzhou. Brian Yang, partner at BIG, said: “The best technology should be a seamless life extension. OPPO’s new R&D headquarters embodies this concept, located inside a stunning geographic location of Hangzhou, combined with dense urban and natural landscape on one side, this will be an ant symbol. architecture of OPPO with elegant philosophy, while improving the quality of life for people in the city ”. BIG looked at how to create the optimal workspace with plenty of natural light while optimizing energy use. From that. The south side of the building will have a central courtyard, the inner facade shaded from solar energy. The slopes create a series of gaps three times the usual height and the courtyards where OPPO employees can interact and socialize. The building will be surrounded by adaptive wind vents oriented towards the angle of the sun. The architects said this would reduce solar energy by up to 52%, thereby reducing energy consumption, glare, reflection and the greenhouse effect. Bjarke ingels, Founder and Creative Director of BIG said: ‘We have been trying to envision OPPO’s future work environment as sustainable on three key points: economic, ecological and social. . ‘, The building has large flexible floors illuminated by the sun and fresh air. The facade has an adaptive roof that removes sunlight ‘. Most of the building will be occupied by OPPO but the first three floors are devoted to public programs including exhibition space, conference center, cafeteria and a garden for outdoor seminars. This urban oasis will provide fresh air, retain water and support a biodiversity public area connected to the daily life of the city. Through this project, Hangzhou will become one of OPPO’s most important research and development centers in China. Going forward, we believe that through our cooperation, OPPO’s R&D headquarters will not only perfectly represent OPPO’s brand identity and culture, but also become an iconic landmark. most in Hangzhou. This will represent a key cornerstone of OPPO’s hundred-year plan. Said Jin Le Qin, Vice President of OPPO.

Read the synopsis: Talking about the current maternal-fetal medical consultation center for fetal heart disease, Yihua He, director of the Beijing Anzhen Hospital’s Maternal-fetal Medical Consultation Center for Cardiology, felt a little emotional: “We see fresh little lives on the screen every day, and we also face many families every day. Worries and troubles. In fact, when a family of children gathered in front of us and asked whether this little life could successfully come to the world, we were wondering whether we could provide the family with more comprehensive and three-dimensional reference information. Of course, only It is not enough to rely on the strength of one department.” “We have a mother exchange group. Yesterday I saw a mother from Qinghai telling her story in the group. She was diagnosed with congenital heart disease in the fetus in early February this year and induced labor locally in mid-to-late March. She blamed herself and kept saying, “If I went to a big city to see it, maybe there would be a turnaround”.” Before the outpatient service of He Yihua at the Cardiology Maternal and Fetal Medical Consultation Center of Beijing Anzhen Hospital, a young prospect who came from Guizhou for treatment Mother Wang Xiaoxiao (pseudonym) said that the baby’s heart development was found to be abnormal during the birth check-up at the local hospital. The doctor suggested that the couple come to Beijing to see Director He for the baby. After speaking, Wang Xiaoxiao touched her belly lovingly with one hand, and tightly grasped her husband’s hand with the other. my country is a populous country and a country with a high incidence of birth defects. According to statistics from the “China Birth Defect Prevention Report 2012”, the incidence of birth defects in my country is about 5.6%. Based on the 16 million births in the country, there are about 900,000 new birth defects every year. “We must have a concept. When the fetus is diagnosed with congenital heart disease, don’t panic.” He Yihua said that in 2011, congenital heart disease accounted for 26.7% of all monitored cases. In the past 10 years, congenital heart disease has consistently ranked first in the incidence of perinatal birth defects among pregnant women in my country, and the proportion of total birth defects is higher than that of other birth defects. “This disease requires detailed classification and evaluation, and some fetuses have good treatment effects and can be self-healed.” Approximately 6 out of every 1,000 newborns suffer from congenital heart disease “People often ask me what is the cause of congenital heart disease. I can only say that there is no one-to-one etiological discovery of congenital heart disease. This is a result of environmental, autoimmune, genetic background, and psychological pressure. Complex results caused by the influence of multiple factors.” Facing the reasons for the rapid growth of congenital heart disease in recent years, He Yihua said, “The environment, autoimmunity, etc. are high-risk factors that lead to congenital heart disease, but the most important It’s the increase in the prenatal detection rate.” Congenital heart disease has a broad spectrum, including hundreds of specific types, and the symptoms vary greatly. Those with the mildest symptoms will have no symptoms for life, and those with severe symptoms will have severe symptoms at birth, such as hypoxia, shock, etc. There are many ways to classify congenital heart disease, which can be divided into structural abnormalities and non-structural abnormalities from the structure; genetic syndromes can be divided into genetic syndromes and non-genetic syndromes. He Yihua introduced that for pregnant women, they may pay more attention to classification based on prognosis. From the prognostic point of view, congenital heart disease can be divided into those with a good prognosis, which do not require surgery or require treatment with a good prognosis; those with a poor prognosis, which can only establish a single mechanism cycle; and those with extremely poor prognosis, often Manifested as malignant arrhythmia, heart failure, etc.

Due to the special physical condition of pregnant women, various examinations during pregnancy are limited. “CT examination is radioactive and cannot be used during pregnancy. The heart rate of the fetus is relatively fast, so the resolution of MRI in the detection of fetal heart is not high. At present, it is the most suitable for prenatal detection of fetal congenital heart disease. The most effective method is ultrasound testing. Taking Anzhen Hospital as an example, the prenatal detection rate of fetal congenital heart disease can reach 96%.”

Generally speaking, for high-risk groups, ultrasound testing can be performed within 15 to 16 weeks of pregnancy, but if you want to see more clearly and make a more accurate diagnosis, 20 to 24 weeks is a better observation window. Similarly, non-high-risk groups can also be observed in more detail during the 20 to 24 weeks of pregnancy.

“In my country, about 6 out of every 1,000 newborns suffer from congenital heart disease. The prevention of congenital heart disease requires a’tertiary prevention’ strategy.”

The first is to remove the cause of primary prevention. As the most direct cause of congenital heart disease cannot be found at present, primary prevention is difficult to achieve, and the effect is not ideal. “Neural tube malformation was ranked first in the entire birth defect disease 15 years ago, but because it has primary prevention measures to remove the cause, such as taking folic acid, the birth defect of neural tube malformation has been greatly reduced. Malformations are only ranked 6th in the incidence of perinatal birth defects in pregnant women.”

The so-called secondary prevention is to make a clear diagnosis before delivery. “At present, secondary prevention mainly relies on ultrasound diagnosis. In fact, ultrasound diagnosis is very effective, almost 100% of the abnormalities in the heart structure can be detected. However, due to problems such as medical equipment and operator experience, the detection results in various regions exist. A certain difference.”

The tertiary prevention is to use various methods to diagnose and treat children who have congenital heart disease early to reduce the harm of congenital heart disease and improve the treatment effect of the child so that the child can recover health as soon as possible.

“In recent years, some scholars have also put forward the concept of’zero-level prevention’, that is, genetic testing before marriage.” He Yihua said, “At present, because of the high complexity of the disease, the complicated pathogenic factors, and the birth treatment The technical requirements are high, and the effects of multiple levels of reasons have led to unsatisfactory prevention effects at all levels.”

Interdisciplinary Maternal and Fetal Medical Consultation Center for Fetal Heart Disease

On the eighth floor of the outpatient department of Anzhen Hospital, before eight o’clock, the front door of the fetal heart disease maternal-fetal medical consultation center was full. The people waiting for medical treatment raised their heads, and the eyes on the masks stared at the electronic screen on the wall for fear of missing their names. From time to time, someone would look around the loudspeakers and pace back and forth in the hall.

Every day, people all over the country stand in front of the consultation center with worry but hope.

Speaking of the current Maternal and Fetal Medical Consultation Center for Fetal Heart Disease, He Yihua sighed: “We see fresh little lives on the screen every day, and we also face the worries and distress of many families every day. In fact, being a family member When we surrounded us and asked whether this little life could successfully come to the world, we wondered whether we could provide families with more comprehensive and three-dimensional reference information. Of course, relying only on the strength of a department is far from enough. ”

He Yihua’s team is in a remote consultation. Photo courtesy of the interviewee.

Beginning in the second half of 2012, He Yihua’s team hired a researcher to conduct a half-year survey among various departments. From six in the morning until five in the afternoon, the investigator will record the information he saw and heard that day, including the information he communicated with the doctor every night.

After communicating with doctors and investigators in various departments for more than half a year, He Yihua has become more aware that whether a child can be born smoothly requires comprehensive evaluation by multiple departments such as gynecology, obstetrics, pediatrics, and pediatric surgery. It requires a combination of imaging, genetic counseling, etc. Multiple materials. After the discussion, not only can provide more decision-making information to the family, but also deepen the mutual understanding and communication between various disciplines. To explore and solve the same problem, you can also run in more tacit understanding between the teams.

“We must do our best to break through the barriers between congenital heart disease prevention, screening, diagnosis and treatment, and let doctors in this logical chain have a cross-perspective macro-thinking, knowing the’upstream’ and “Downstream” does not stick to the cross-section of a single subject.” He Yihua said, “I and the hospital leaders applied for the establishment of a consultation center, and they are very supportive. Now our consultation center has developed into an interdisciplinary comprehensive consultation center.” Since 2013 Since the establishment of the Maternal and Fetal Medical Consultation Center for Fetal Cardiology in 1999, it has provided diagnosis and treatment services for over 40,000 patients.

“Artificial Intelligence + Remote Network Technology” Solve the Problem of Imbalance between Supply and Demand in Primary Medical Care

“Compared to the number of fetus groups that need to be checked, there are still too few doctors with high diagnostic levels.” He Yihua said, “However, we now also provide a set of corresponding solutions, which is’artificial intelligence + remote network technology’. .”

At this stage, there are still gaps in medical resources between my country’s regions and between urban and rural areas. Many grassroots areas are restricted by technical equipment, personnel experience and other reasons, and cannot provide local pregnant women with medical services and medical advice comparable to those in major cities. According to a report from the Central Broadcasting Corporation, some provinces and cities have not included the free pre-pregnancy health check and other work funds into the financial budgets at all levels or the budget is small, resulting in a low level of intervention for birth defects. In some provinces, the pre-pregnancy check-up rate in rural areas is less than 25%.

Hospitals in Beijing, Shanghai, Guangzhou and Shenzhen or some other eastern coastal areas have a high level of diagnosis, but there is still a major problem of imbalance between supply and demand in terms of the annual demand for fetal heart examinations.

He Yihua introduced that artificial intelligence screening technology is still being used within a certain range. Doctors and patients in various regions can input relevant medical data and information into the corresponding technical background to understand whether the prognosis of the fetus is good. In addition, it can also pass The corresponding equipment performs the diagnosis of fetal congenital heart disease. At this stage, the accuracy rate of artificial intelligence screening has reached 87%, which is higher than the average detection level of 43% in Europe and the United States. “Of course, we do not regard technology as the’gold standard’, but supplement it with manual review. We are still strengthening collaboration and learning in human-computer interaction.”

The consultation center has formed a remote collaboration network with nearly 200 hospitals across the country. Realize the interconnection and data sharing between cooperative hospitals through remote network technology. On the large smart screen of the consultation center, ultrasound diagnostic images of fetuses in collaborative hospitals can be synchronized. Local doctors can communicate with the consultation center through the remote network at any time when they encounter doubts.

“Artificial intelligence and remote networks can be collectively referred to as’appropriate technologies at the grassroots level.’ For us, we want to sink high-quality medical resources and medical services to the grassroots. Through these grassroots accessible technologies, the broadest Demand groups.”

Learn to tolerate, life is a miracle

Years of life in diagnosing fetal congenital heart disease also made He Yihua and her team think about a question: What perspective should we look at imperfect life.

“Some fetuses can be treated similarly to normal children after birth, but many parents are pursuing the “perfection” of their children. No matter how much work we do, it will not help. Of course, each family’s expectations and economic conditions are different. We also understand.”

“Parents will worry about the pressure that their children will face in their future work and life, the incomprehensible vision of others, and even the mockery of their children’s defects. In fact, each of us is’imperfect’, and there are known or unknowable defects. The most important thing is how we view “Imperfect Life” and “Imperfect Life”.”

There is a movie called “Miracle Boy”, which tells the inspirational story of Ogi, a boy born with facial defects. Augie was taught at home by his parents because of facial defects. In the fifth grade, he was given the opportunity to study in a regular school. Ogi, who was new to school, was ridiculed and bullied by his classmates because of his looks, but with the help of his father, mother, sister, teacher and friends, he finally found confidence and used his actions to change the views of others.

“I know that there is a ‘8772’ band composed of patients with rare diseases in Beijing. These children get together because of rare diseases but love music. They have released albums and held their own concerts. I think these A child just changed a window to look at the world. They are very sunny and have their own stable happiness.”

“Perhaps, for you and me, if you learn to be tolerant, life is a miracle.” He Yihua’s face was firm, her eyes gleaming.

Nguyen Ngoc Ga, a photographer living in Da Lat (Lam Dong) often spends once a year to visit his hometown of Quang Ngai. Leaving the busy streets of tourists in Da Lat, he felt a peaceful breath in his days back home. “I come from Quang Ngai but only come back once a year so I don’t know the point, I have to look it up online. In the morning, I often go for a walk and record the daily life of the people. very beautiful, “shared Ngoc Ga. In the photo, a resident is catching mussels in Sa Huynh. During her return to her hometown, Ngoc Ga spent her time traveling to many places such as My A Sea, Sa Huynh Sea, Sa Huynh salt field, Ly Son island, Ba To mountain area … “Quang Ngai is a pristine land, The weather is harsh, hot and often subject to natural disasters and floods, “he said. My A sea mouth (Duc Pho) has a vague color in the moment of harmony between light and darkness. This is not a tourist destination that is often interested by tourists. This place mainly concentrates fishing boats of fishermen. Walking around this area you will also find breakwaters covered with green moss. People mentioned a lot about the breakwater and moss season in Phu Yen. However, few people know that in Quang Ngai, there are also wave-breakers in this beautiful picture. “The scenery here is beautiful but the tourism has not made a breakthrough. I think Quang Ngai needs to invest heavily in island tourism, connecting tours, routes, expanding the convenient shuttle system to Ly Son”, he commented. During the day wandering at the estuary of My A sea, Ngoc Ga waited until night to record the moment of the galaxy on top of the shipyard. A place with little light and fresh air like Quang Ngai is a great destination for photographers looking for “milky way” hunting. A corner of the starry sky above the waves covered with green moss. The gentle and peaceful life of the local people makes Ngoc Ga want to go more and record the moments of everyday life. These green fishing nets are indispensable tools for livelihoods for marine fishermen. However, it also often appears in the photos of many photographers. They often refer to these nets as “the ribbon of the sea”. “There are lonely trees in my hometown, but no one mentioned them,” said the photographer. This photo was taken by Ngoc Ga on Be Island (Ly Son). Compared to many other regions in Quang Ngai, Ly Son is more popular with tourists. However, according to Ngoc Ga, Quang Ngai deserves to be known more, instead of just Ly Son as it is now. “My hometown has a favorable geographical position such as Da Nang – Quang Ngai expressway, Chu Lai airport, Dung Quat deep sea port. More than 100 km of beautiful coastline with Ly Son, Yen ganh, Sa Huynh. .. Quang Ngai’s topography is also diverse and many relics, cultural and historical sites “, Ngoc Ga said.

Editor’s guide: The difference between the C-side and B-side products determines the different responsibilities of the product manager in the life cycle. From the perspective of design thinking, the author of this article will talk to us about the differences between B-side and C-side product managers.

In the post-epidemic era, demand for B-end products such as online office and online and offline integration has erupted, and the recruitment of B-end product managers has also grown rapidly.

I have been engaged in the design and operation of B-side and C-side products in the communications industry for many years. Recently, I switched to responsible for large-scale B-side products. The first two days of the project had to recruit a new product. I was quite impressed by one of the applicants with 5 years of work experience. , The other party said, “There is not much difference between the B-end and the C-end, no matter which industry is the B-end or the C-end,” he took this opportunity to analyze the difference between the B-end and C-end products.

What is a B-end product? There can be many types of product classification, which are defined by different user groups. Products can be divided into B-end products and C-end products. Typical B-end products include CRM, ERP, OA, Zhongtai, etc.; C-end products are WeChat, Douyin, Jingdong Taobao, etc.

This article will focus on the five points of user-oriented, design starting point, design focus, MVP thinking, and target value, and analyze the difference between the design thinking of B-end and C-end product managers.

1. Different for users

B-side customers are enterprise-level users, and the user group is stable and unified.

The customers of the B-end products are employees in the enterprise, and such users have common characteristics at the enterprise level to form a collective personality. The user needs of B-end products are enterprise-level, and personalized needs are usually ignored. However, users of B-end products may usually have multiple roles.

Taking the data center as an example, users may include business personnel, data mining experts, operation and maintenance personnel, managers, etc., usually multiple people, multiple posts, multiple posts, multiple posts per post, and multiple people in one post. Demands in different scenarios.

The users of C-end products are individual and diversified.

Of course, the C-end product manager can form user portraits by analyzing the user’s behavior characteristics, and classify users into groups. These characteristics may include user age, gender, location, hobbies, etc. But each user is personalized, and each user can put forward requirements and product iteration opinions, but the product manager needs to conduct unified screening based on the current product positioning and development stage to remove the false and keep the truth.

Two, the target value is different

The B-end products focus on corporate office and improve production management efficiency.

The starting point of demand for B-end products is to improve the internal management or production efficiency of the enterprise, and the theme around it is the production practice of the enterprise. It is often seen how much efficiency can be improved, what processes have been optimized, and how much costs have been reduced after the product is launched. However, it is relatively complicated to measure the value of B-end products. Because there are many influencing factors in actual production, it is difficult to measure directly through data.

C-end products take care of food, clothing, housing and transportation, eating, drinking and having fun, and shoulder the important task of traffic acquisition and commercial realization.

The function of the product concerned is whether it can meet the needs of users and whether it can solve the pain points encountered at present. For example, are you hungry? Meituan is to solve the problem of users who don’t have time to eat, but want to eat better (so the crossover defeats the instant noodles), WeChat solves the user’s instant messaging problem for free (therefore directly The short message service of the operator).

Three, the design starting point is different

If the product design from 0 to 1 is divided into three stages: demand analysis, product design, and product landing, by analyzing and comparing the key tasks of each stage, it is obvious that the product design of the C-end and the B-end is different, and the product manager design of the B-end The starting point is business status diagnosis (requirements survey).

As mentioned in the previous article, the B-end product is for the employees of the enterprise, and its purpose is to improve the management and production efficiency of the existing enterprise. Therefore, it is first necessary to understand the business content and development strategy and tactics of the enterprise through business research; secondly, it is necessary to diagnose the enterprise For the current model problems, process problems or management problems that exist in the current development, the corresponding solutions are finally proposed.

The starting point of C-end product design is market research. Common C-end product design thinking usually starts from market research and competitive product analysis. This is also determined by the C-end product’s goal of “maximizing the pursuit of commercial value.”

Through market analysis, we can get a business canvas and understand the market space and future prospects to determine whether it is necessary to make the product. Simply put, whether it can make money. Through the analysis of competitive products, we can understand the situation and core capabilities of competitors, so that we can make better products, so as to realize that everyone has no one, everyone has one, and everyone has one. Simply put, it is to learn the advantages of the opponent, and to use their own strengths to build barriers to competition.

Four, the design focus is different

The focus of B-end product design is abstract modeling and business processes.

The business complexity behind the B-end products is high. People, division of labor, collaboration, processes, and rules may be adjusted at any time. Product managers need to conduct in-depth analysis of the business, abstract the seemingly disorganized business, and abstract the commonality from the business process and business appearance. Summarize and abstract the core business essence.

There are many abstract modeling methods for business processes, such as: ER, UML, etc., through business modeling work is the basis of B-end product design, excellent business modeling will help better carry out product role and process design, Authority and management design, interface and report design.

C-end product design emphasizes interactive experience. The number of users of C-end products is usually 10,000 or even 100 million, which is much higher than that of B-end products. In addition, C-end users require very low learning costs and operating costs. A bit of uncomfortable experience may cause users to abandon the product, and user experience will directly determine user retention.

Therefore, the position, color and size of each button of the C-end product, the design and color of each picture, the number of words in each sentence, and the language must be fully thought, demonstrated, and tested to provide the ultimate interactive experience.

Five, MVP thinking is different

The B-side MVP is the smallest closed loop that supports a certain business scenario.

The MVP of the B-side product is usually not an MVP. Why do you say that? It is because the B-side product is designed to solve corporate problems. Such problems cannot usually be solved independently by one or two product function points, and a complete product closed loop is required. Delivery, which also requires the B-side product manager to conduct systematic thinking in the design phase.

C-side mvp can grasp a certain core pain point of the user. C-end products are more based on the business profit model. An MVP version is a preliminary verification of a product Idea. For example, many early MVPs of e-commerce websites were in the form of merchants posting posts on BSS forums and users following posts.

However, even now, there is still no shortage of e-commerce platforms that use the WeChat ecological solitaire to sell products at the lowest development cost.
