(Photo by Bangkok Post Office) On June 15, Thai Prime Minister Prayut Chan-o-cha apologized to the people for delays in the nationwide Covid-19 vaccination program and said there were many reasons for the delay. this late. The Bangkok Post quoted Prayut as saying that the Thai government only received small batches of vaccines, not large batches at the same time. At the same time, vaccine shortages and delay in vaccination schedules only occur at vaccination sites with high vaccination capacity and have used up allotted vaccines. According to Prayut, the distribution of Covid-19 vaccines cannot be done quickly, and the production and quality control of vaccines are very time consuming. Many other countries in the world also have this problem. In addition, Thailand’s vaccination program was also adjusted to speed up the vaccination of high-risk groups in epidemic areas, thereby controlling the epidemic and protecting the activities of health workers. machine. This also affects some people who have previously registered for the Covid-19 vaccine. In addition, the vaccination process also involves many agencies and organizations, and misunderstandings can occur in the immunization coordination process. Prayut said those who had already registered for the vaccine but had their appointment rescheduled would not have to re-register and their registration would remain valid. He said: “As the Prime Minister and Director of the Thai Center for Covid-19 Situation Administration (CCSA), I am the commander-in-chief of the fight against the Covid-19 pandemic in Thailand. I apologize for the problems that have occurred and I will take full responsibility.” Prayut said the government has distributed 7 million doses of Covid-19 vaccine to provinces across the country and so far 6.5 million doses have been administered to people. He affirmed that he also closely follows information about vaccinations and does his best to solve problems that arise. “We will find ways to solve the problems to ensure the maximum benefit for the people and reduce their anxiety,” he said. The Thai government has now ordered 100 million doses of the Covid-19 vaccine to immunize about 50 million people, or 70% of the country’s population, this year. Prayut confirmed that Thailand will order more vaccines to be able to increase the number of people vaccinated to 80 to 90% of the population next year.

The apology was made by Prime Minister Prayuth after the Thai public expressed displeasure over the slow implementation of the vaccination campaign. Prime Minister Prayuth said that despite ordering a large number of vaccines, the Thai government has only received a small amount of the vaccine. Vaccines are now concentrated in large vaccination points, with faster vaccination rates, where almost all of the vaccines they are distributed are used up. Although Thailand has been transferred technology, the production of a vaccine takes a long time, not to mention the quality control procedures, which every country has to face, Prime Minister Prayuth said.

In addition, vaccination is currently focused on the most vulnerable populations in high-risk outbreak areas in the Thai capital, in order to prevent the disease from spreading, as well as to maintain the operation of health facilities. factory. This affects those who have already signed up for vaccinations, Prime Minister Prayuth acknowledged. In addition, Prayuth also said that the vaccination campaign involved many organizations, and the lack of harmony in the coordination process also affected the speed of vaccination deployment. The Thai government has ordered 100 million doses of the Covid-19 vaccine, with plans to vaccinate 50 million people, or 70% of the population, this year. Prime Minister Prayuth said Thailand’s goal is to buy enough vaccines to raise vaccination rates to 80-90%.

See through smoke and fog, map a person’s blood vessels while monitoring heart rate – without skin contact; look through the silicon wafers to check the quality and composition of the electronic board. Those are some of the many functions of infrared camera new, developed by a team of researchers led by electrical engineers at the University of California San Diego. The camera detects a part of the infrared spectrum known as shortwave infrared light (wavelengths between 1000 and 1400 nanometers), which lies just outside the visible spectrum (400 to 700 nanometers). Shortwave infrared imaging, unlike thermal imaging, detects much longer infrared wavelengths emitted by the body. The camera works by shining short-wave infrared light at an object or area of ​​interest, then converting the reflected low-energy infrared light back to the device into shorter, high-energy wavelengths. than the human eye can see. “It makes invisible light visible,” said Tina Ng, professor of electrical and computer engineering at UC San Diego Jacobs School of Engineering. When technology Infrared imaging has been around for decades, where most systems are expensive, cumbersome, and complex, often requiring a separate camera and monitor. They are also often made with inorganic semiconductors, which are expensive, hard, and contain toxic elements such as arsenic and lead. The infrared camera that Ng’s team has developed overcomes these problems. It combines sensors and display into a slim, compact and simple device. It is made of organic semiconductors, so it is low cost, flexible and safe for use in biomedical applications. It also offers better image resolution than some of its inorganic versions. The camera is made up of multiple layers of semiconductors, each hundreds of nanometers thin, stacked on top of each other. Three of these layers, each made of a different organic polymer, are the key elements of the image: the photodetector layer, the organic light-emitting diode (OLED) display layer, and the blocking layer. electrons in the middle. The photodetector layer absorbs shortwave infrared light (low energy photons) and then generates an electric current. This current flows to the OLED display layer, where it is converted into a visible image (high-energy photons). An intermediate layer, called an electron block, keeps the OLED display layer from losing any current. This is what allows the device to produce clearer images. Another special feature is camera effective in providing optical and electronic indicators. “This makes it multifunctional,” says Li. For example, when the researchers shined infrared light on the back of the subject’s hand, the camera provided an image of the subject’s blood vessels while recording the subject’s heart rate. The researchers also used their infrared camera to see through the fog and a silicon wafer. In one test, they placed an “EXIT” patterned photosphere in a small room filled with smog. In another setting, they placed a photorealist patterned “UCSD” behind a silicon wafer. Infrared light penetrates both smog and silicon, making it possible for the imagineer to see the letters in these illustrations. This would be useful for applications such as helping self-driving cars see in bad weather and checking for silicon faults. The researchers are currently working to improve the performance of this type of camera.
