Immediately after, the Center for Disease Control of Dong Thap province conducted a confirmation PCR test sample for this case and the result was negative for SARS-CoV-2. Dong Thap province has two confirmed PCR testing facilities. Explaining this result, the Dong Thap health sector said that usually, rapid tests have high sensitivity to easily screen all suspected cases so as not to miss subjects when investigating and tracing. But with the rapid test, it is not possible to confirm that the subject has Covid-19 but after performing the rapid test, a PCR test must be performed to confirm the screened result. New PCR test confirms whether the subject has Covid-19 or not. Related to the above case, today, there has been a lot of information on social networks that reflects incorrectly, causing confusion and insecurity in public opinion. Phuong Chau Sa Dec International Hospital is operating normally, well streamlining all stages, well implementing regulations on epidemic prevention and control for medical examination and inpatient departments. Dong Thap province’s functional sector recommends that people should select official information from competent professional agencies to speak, avoid spreading and sharing false information that causes confusion among the public.

Samsung launched the world’s smallest camera sensor (Image: The Verge) Recently, Samsung has launched a new camera sensor for smartphones, with the smallest pixel size in the world. ISOCELL JN1 is a 50MP sensor, 1/2.76 inch size is relatively small, pixel size is only 0.64 μm. Camera experts often say that the smaller the pixel size, the worse the image quality and the higher the noise. So why does Samsung continuously release sensors with such small pixel sizes? According to Samsung, the small camera sensor can still ensure the resolution of the photo. The smaller sensor size makes it easier to design telephoto and ultra-wide-angle camera modules, as the lens structures of these cameras are more complex than conventional cameras. That means the camera will be less convex. Like many cameras the sensor can capture images at 12.5MP resolution, which equates to a pixel size of 1.28 μm. Samsung also integrates ISOCELL 2.0 technology, which increases light sensitivity by 16%. Samsung says the JN1 is currently in mass production, so it is likely to appear on Samsung smartphones in the near future.

For centuries, apple growers in Japan’s Aomori Prefecture have been creating beautiful heirloom apples using the mojie ringo technique. The process is pretty simple, which basically means exposing the apple to sunlight for a period of time and then applying stencils to ensure that certain parts of the apple peel are discolored. Usually, mojie ringo apples are decorated with messages and symbols of good luck and prosperity, and given as gifts. Large apple varieties like Mutsu or Stark Jumbo are best suited for the mojie ringo technique, as they provide more surface area for intricate designs. The apples using the mojie ringo technique are extremely beautiful. Preparations begin in January, with a pruning operation, to ensure that the remaining flowers receive plenty of sunlight. Growers then use soft wands to hand-pollinate each apple tree flower, and then when the fruit begins to form, they are covered with a laminated plastic bag to both protect the berries from Pests just block sunlight. Keeping apples in the dark for long periods of time increases their sensitivity to light, so when they remove the plastic bags, they begin to produce anthocyanins, a component that gives the skin its red color. In the final stage of the mojie ringo process, stencils are applied over the surface of the apple to ensure that only the skin around the stencils turns red. The stencils are removed during harvesting, revealing the almost white skin underneath. Stencils need to be flexible, as the fruit continues to grow, and otherwise, the style may suffer. According to Culture Trip, the Mojie Ringo technique was perfected by Aomori farmer Haruo Iwasaki, father of Chisato Iwasaki, one of today’s most talented apple artisans. Although the mojie ringo technique may seem quite simple, it requires a lot of work and patience over the long term, and for many growers the effort and attention are insignificant economically. That’s why the old tradition is slowly fading away, only a few Aomori gardens still keep this technique. The mojie ringo technique is also very popular in China and other Asian countries under the name of “tattooing apples”.

The large-capacity “field” Covid-19 laboratory at the Bac Giang Center for Disease Control has been fully installed with the cooperation and transfer support of the Military Medical Academy (Hanoi). This area has an area of ​​​​about 200 m2 and was built quickly in 3 days. The center consists of 8 specialized rooms. In which, 2 laboratories meet biosafety level 2. The most dangerous room is the initial sample processing room. This is the workplace of many officers from the Military Medical Academy, Bac Giang Center for Disease Control and volunteer technicians. Responsible for operating the laboratory is Lieutenant Colonel, Dr. BS Ho Huu Tho (Head of Department of Gene Technology and Cell Genetics, Military Medical Academy). According to Dr. Tho, the special feature of this laboratory is that the SARS-CoV-2 virus detection process is highly sensitive, with the cost savings being reduced by nearly half compared to traditional methods. At the same time, the center has the capacity to test tens of thousands of people every day. According to Dr. Tho, this is the world’s first gene technology, using artificial intelligence to analyze PCR results to detect SARS-CoV-2 pathogens (known as AIMS RT-PCR technology). The sensitivity of this method was evaluated against an in vitro RNA standard set for a detection threshold of 7.2 copies/reaction, nearly 7 times lower than the WHO recommended procedure, when evaluating under the same experimental conditions (50 copies/reaction). This study was clinically evaluated on 142 positive cases, 1,034 negative cases for SARS-CoV-2 and 14 other respiratory viruses. The sensitivity and specificity of the method were both 100%. More importantly, the procedure was successful in mixing 100 patient samples in a single real-time reaction without compromising sensitivity. As such, this is a simple, super-sensitive and potential test method for large-scale screening of SARS-CoV-2 with cost savings many times over. According to Dr. Tho, this method is like a weapon we switch from a defensive state to an attack against the Covid-19 epidemic. To communicate with the staff working in the lab, the commander had to use a walkie-talkie system because the windows were always foggy because of the mist and Chloramin B disinfectant. Besides, the technician was wearing clothes For protection, entering the lab will be called by the number corresponding to the job they are undertaking. After each opening to receive samples, the room is sprayed with disinfectant to avoid the risk of infection. All generated waste is also collected and treated according to regulations of the Ministry of Health. To maintain testing capacity, nearly 100 cadets of the Military Medical Academy are divided into small teams working for 8 hours, with 3 rotating teams each day to ensure that the laboratory is always open 24 hours a day. Tran Hoang Minh (student of Military Medical Academy) and friends relax before the shift. He is in charge of the work of separating and taking samples, so the risk of infection is very high. However, Minh feels proud to work at this center. “The laboratory capable of large-scale testing is a very powerful weapon in the fight against the epidemic. With mobilized human strength, strong weapons and high determination, I believe the epidemic will be quickly controlled.” male students share.

With the Mojie Ringo technique, Japanese farmers harness the power of the sun to create beautiful apples without the use of any chemicals. This process is called apple tattooing. Basically, apple growers expose the fruit to sunlight for a period of time and then use stencil molds to shape as desired, keeping the rest of the color unchanged. Usually, the looker will decorate the Mojie Ringo apple with writings that carry messages and symbols of luck and prosperity. Large apple varieties such as Mutsu or Stark Jumbo are best suited to apply the Mojie Ringo technique. With a lot of surface area, one can create complex designs. To apply this perennial technique, apple growers start preparing in January. They prune the branches to make sure the flowers get the most sunlight Growers then use soft-bristled wands to hand-pollinate each flower. When the fruit begins to form, people cover the apple with a multi-layer plastic bag to both protect the fruit from pests and block sunlight. Keeping apples in the dark for a long time increases their sensitivity to light, so when you remove the plastic bags, apples begin to produce anthocyanins, a component that gives the skin its red color. In the final stage of the Mojie Ringo process, a printed stencil mold is placed on the surface of the apple to ensure that only the skin around the stencil turns red. Placing the stencils needs to be flexible, as the fruit continues to grow, otherwise the style may suffer. The Mojie Ringo technique was perfected by Aomori farmer Haruo Iwasaki, father of Chisato Iwasaki, one of today’s most talented apple artisans. Although the Mojie Ringo technique seems quite simple, it requires a lot of work and patience in the long run. It is also one of the reasons many growers no longer pursue this traditional look. There are only a few Aomori orchards that produce eye-catching apples.

Users only take 10 seconds to breathe into the machine and less than 2 minutes later have COVID-19 results. Photo: Straits Times According to the Singapore Straits Times, the device will ensure the safety of movement and inspection at large-scale events. Previously, local health technology company Silver Factory worked with the National Center for Infectious Diseases (NCID), Changi Airport and security company Certis to develop the device. Silver Factory’s ventilator, called TracieX, is proven to give results nearly as accurate as a PCR test, which takes only about 2 minutes. Compared with PCR test, the sensitivity rate of TracieX ventilator is above 95% and its specificity is above 99%. Device sensitivity is the ability to confirm which test samples are positive, while specificity is used to confirm a negative. The price for a test with this device is only 20 USD (about 460,000 VND). The device has been tested at NCID, Changi and Certis airport terminals with over 400 participants. During a test at Changi Airport last month, passengers were randomly selected and asked to voluntarily provide breathing samples. “Testing with a ventilator will be less invasive, effective and quick to give results. From there, creating favorable conditions for passengers to fly,” said Mr. Abert Lim – Vice President in charge of passenger experience of Changi Airport Group – said. Silver Factory Technology’s TracieX ventilator uses a sensor chip to identify molecular traces in the breath of patients with COVID-19. Medical staff take a breath sample and put it into the processing device to read the results. Photo: Straits Times Disposable breathing tubes with control features keep infectious material sealed, thus preventing direct contact of these materials with others, such as healthcare workers. The user will breathe into the device for 10 seconds. The device is then inserted into a portable reader for analysis and results. The process is completed in less than 2 minutes. Silver Factory is currently working with Enterprise Singapore under the Singapore Ministry of Trade and Industry with the ambition to bring this technology overseas.
