The route follows the highway: Pham Van Dong street, Trang Bom – Hoa Hung railway, Ring 2 route (located in Thu Duc city) and connects the rails directly to the Thu Thiem light rail route – National airport. Long Thanh economic zone at the Ring Road 2 intersection with the Ho Chi Minh City – Long Thanh – Dau Giay Expressway. Ho Chi Minh City also suggested that it is necessary to study the direction of urban railway No. 4b directly connecting with T1, T2, T3 terminals of Tan Son Nhat Airport. The City People’s Committee assessed that this route alignment option, when built, will contribute to the development of the urban railway system in Thu Duc City, convenient for traveling between areas. Talking to Dat Viet, aviation expert – Assoc. Prof. Dr. Nguyen Thien Tong, former Head of the Department of Aviation Engineering, Ho Chi Minh City University of Science and Technology, pointed out 3 problems that make the railway connecting Tan Son airport Nhat – Long Thanh is not feasible. Firstly, about the need to build this railway line. According to Mr. Tong, it is not possible to say here in general that there is a need or indiscriminately stating a few numbers, lacking actual research, but needing specific quantitative analysis. “How many passengers will travel on this railway connecting Tan Son Nhat with Long Thanh? There must be data and an explanation for why there is such data”, he emphasized. Ho Chi Minh City People’s Committee wishes to have a railway connecting Tan Son Nhat international airport to Long Thanh international airport. The expert said that, in the past, passenger demand for Long Thanh airport was calculated from the passenger demand forecast for Tan Son Nhat airport and then subtracted from the capacity of Tan Son Nhat airport. This simple calculation is based on the assumption that all excess passenger demand of Tan Son Nhat airport will be transferred to Long Thanh airport. “It is expected that when Tan Son Nhat airport is overloaded with over 50 million passengers, and the demand is up to 75 million passengers, then 25 million passengers will go from Tan Son Nhat through Long Thanh airport. This calculation method is very mechanical and mechanical, potentially posing a huge risk in forecasting passenger demand for Long Thanh airport”, Assoc. Prof. Dr. Nguyen Thien Tong commented and affirmed that passengers do not wait until Tan Tan. Son Nhat will run out of seats and then go to Long Thanh, but they will go to any airport they want to go to. rather than going through Tan Son Nhat. So which passengers from Tan Son Nhat to Long Thanh? Only passengers on domestic flights to Tan Son Nhat need to go to Long Thanh to connect to international routes. And vice versa, only passengers on international flights to Long Thanh without a connection from there to other provinces and cities such as Hanoi, Hue, Da Nang… will return to Tan Son Nhat to fly away. The number of international passengers traveling between these two airports is not much, so there is no need. That is the plan that the Ministry of Transport wants to use Tan Son Nhat airport as a domestic airport and Long Thanh as an international airport. The option of organizing two airports like this is inefficient and unfeasible. In principle of international airport operation, domestic and international terminals must be close to each other. It is best that Long Thanh International Airport is a transit airport for long-distance international flights such as going to Europe and America that need to collect passengers all over the country, and short-distance international flights such as going to Asia. Tan Son Nhat airport and other international airports take over to serve the residential areas of the provinces near the airport. “Most of the excess passenger demand of Tan Son Nhat airport will be transferred to using regional airports, especially passengers in the Mekong Delta will use Can Tho airport. Therefore, from now until then Once the construction of Long Thanh airport is completed, Can Tho International Airport and Cam Ranh International Airport will also be developed to reduce the load on Tan Son Nhat, so that by then there will not be many international visitors for the airport. Long Thanh and other airlines are not foolish to open flights when there are no guests,” said Assoc. Prof. Dr. Nguyen Thien Tong. The second point noted by the expert is the financial and economic efficiency of the railway. Assuming that when the construction of this route is completed and tickets are collected, will the collected ticket money offset the site clearance costs, railway construction costs, operating costs… or not? Not to mention, if the fare is higher than other means of transport, it is easier for passengers to choose to go by road rather than this railway. “We have to figure out how much those customers pay for a metro ticket between Tan Son Nhat and Long Thanh, how much is the money collected in a year, how many years will it take to recover the capital? Midway station to serve guests wishing to go to Long Thanh and Tan Son Nhat, that is only secondary,” the expert pointed out. The third and most important point, according to Assoc. Prof. Dr. Nguyen Thien Tong, is where to invest, especially in the context of high public debt today. He also reiterated his concerns about Long Thanh airport. The project has been pressed to start construction since the beginning of this year, but worries about the investment capital, feasibility and economic efficiency of the project are still there. The state has to invest a lot of money to build Long Thanh airport, and also has to invest a lot in connecting traffic between the airport and Ho Chi Minh City, the area from the South Central region, and the Mekong Delta to bring tourists. to the airport. However, when the airport and traffic connection system is completed, whether there will be visitors to Long Thanh is still an open question and in the event that Long Thanh airport has no guests, it will be a waste. extremely large and must have someone responsible.

Artwork/INT As a person with more than 20 years of research on Ho Guom turtles, Assoc. Prof. Dr. Ha Dinh Duc, former senior lecturer at the University of Natural Sciences (Hanoi National University) still has many doubts. Hoan Kiem Lake turtle is the only species loài Assoc. Prof. Dr. Ha Dinh Duc said that ten years ago, the Asian Turtle Conservation Program posed the problem of searching for individual Ho Guom turtles living in other places to pair for the purpose of species conservation. Since 2006, when he discovered that Dong Mo Lake is also likely to have at least one individual of Ho Guom tortoise, he disagreed on the subspecies. Although he went to the place and studied on photos, he found that the Dong Mo lake turtle was completely different in terms of the Sword Lake turtle morphology. Sword Lake turtle is a new species of turtle, the world’s scientific name is Rafetus leloii because this turtle is associated with the legend of King Le returning his sword on Luc Thuy lake in the 15th century, the lake changed its name to Hoan Kiem lake (Ho Guom). . The word “Rafetus” is the name of the genus of turtle, which is derived from the name of the river Raft in India. “leloi” is the species name, named after Le Loi. The person associated with the legend returns the Treasure Sword to the Turtle God. As a rule, the species name is one word, not capitalized, so the two words Le Loi write together as leloi, and add the character ‘i’ to become leloi. In the International Conference “Sustainable Development – Hanoi Capital – City of Culture, Heroes, For Peace” on the occasion of the 1,000th anniversary of Thang Long – Hanoi, once again Assoc. Prof. Dr. Ha Dinh Duc again Announcement on Sword Lake Turtle a new species of tortoise for science. “It can be affirmed that the Asian Turtle Conservation Program has never studied the Sword Lake Turtle in Hoan Kiem Lake but only investigated the Rafetus species. Dong Mo turtle and Chinese tortoise are not Sword Lake turtles”, said Assoc. Prof. Dr. Ha Dinh Duc. Sword Lake Turtle has the largest size of freshwater turtles in Southeast Asia, as well as in the world. Ho Guom tortoise has a white spot on the top of its head and is slightly skewed to the left. Eyes are rounded slightly upward, but do not rise above the surface of the head. The nostrils open to the anterior limit of the anterior jaw bone. The ivory-white horns cover the anterior jaw bone. The fleshy lip encloses the outer margin of the upper jaw and the posterior half of the lower jaw. The back of the head, neck and carapace are light gray. The underside of the chin, neck and bib are pale pink. The carapace is oval in shape, the spine is slightly concave, without spots or stripes. The shell is covered with soft frilled skin that extends beyond the outer margin of the carapace. The fringe of the skin is thin, the back is elongated and slightly cambered. The upper horn covers the anterior jaw bone and the anterior half of the maxillary bone. The lower horn covers the anterior half of the dentate bone and the anterior part of the coronal bone. The limbs are very strong, the feet have wide swimming webbed and have 3 large horn claws. Assoc. Prof. Dr. Ha Dinh Duc said, in history books as well as in legends, there are no documents or stories about a large turtle that once lived in Luc Thuy Lake. It was not until the 15th century that people knew about this turtle through the legend of Hoan Kiem of King Le. So far, there are no documents or information about this large turtle in any water body of Hanoi. Based on the results of comparative research on morphology with large soft-shelled turtles in the world, as well as in Southeast Asia, and discussed with international turtle researchers, such as: Prof. Kraig Adler – University Cornell (USA) and two other experts, Dr. William P. McCord and Dr. Patrick J. Baker, Assoc. Prof. Dr. Ha Dinh Duc found that Hoan Kiem Lake turtle species is completely different. Assoc. Prof. Dr. Ha Dinh Duc. Sword Lake has only one “turtle” “Someone said there are 2-3 “turtles” in Hoan Kiem Lake. But from the time I started researching until the “old man” passed away, I confirmed that Sword Lake had only one “old turtle”. Even when the “grandfather” was weak, everyone trembled when deciding to bring him up. Seeing 2 bubbles of water, many people said that there were 2 “old turtles”, after picking up the “tools”, they thought that there was another “tool”, possibly bigger. However, there is nowhere to catch. Personally, I find that “old turtle” has actions that are really difficult to explain”, Assoc. Prof. Dr. Ha Dinh Duc shared. In many interviews with the press decades ago, Assoc. Prof. Dr. Ha Dinh Duc always expressed the need to find additional sources, because he affirmed that Hoan Kiem Lake has only one “turtle”. . In 2016, the “old turtle” died, he was also a consultant to make a template to look like “the old man” as when he was alive. At present, despite his advanced age, whenever he hears that there are descendants of the “grandfather” he is on the road again. Assoc. Prof. Dr. Ha Dinh Duc’s whole life has been with the University of Hanoi (now the University of Natural Sciences, Vietnam National University, Hanoi). At the age of “rare and old”, Assoc. Prof. Dr. Ha Dinh Duc still has many concerns with Hoan Kiem turtles. On December 18, 2020, the Hanoi Department of Agriculture and Rural Development, in collaboration with the Asian Turtle Conservation Program (ATP), announced the sex determination results of Hoan Kiem turtles in Dong Mo Lake. Hanoi). The results of genetic testing published by scientists have confirmed that the female turtle caught in October 2020 is a species of Rafetus swinhoei, a soft-shell turtle that is on the verge of extinction. This tortoise is also known as Giai Sin-hoe – Hoan Kiem Turtle. Assoc. Prof. Dr. Ha Dinh Duc also visited the place to see this trapped turtle. He said that although the genetic test results match with the Ho Guom tortoise, he is still “troubled”. Because in terms of appearance, the individual turtles in Dong Mo and Xuan Khanh lakes are not like the “old turtle” of Hoan Kiem Lake as he has known so far. To classify turtles, people rely on morphological characteristics and genetic testing. According to his observations, the Dong Mo turtle does not have the same characteristics as the Sword Lake turtle. “I observed that this turtle’s head is more pointed, the snout is more pointed, and has a very different pattern. The structure of the turtle’s eye is also not the same as that of the Ho Guom turtle I know. I have no knowledge of genetics or genetic engineering, but I am skeptical. Sword Lake Turtle is a new, endemic and rare species of turtle, but this turtle in Dong Mo looks like many common turtle species. I think it is possible that it is the same species of turtle, but belongs to a different species, a different breed… Hopefully scientists will clarify this with concrete evidence,” wondered Assoc. Prof. Dr. Ha Dinh Duc. Currently, there are two specimens of Ho Guom turtle. The first specimen died on June 20, 1967 and the second specimen died on January 19, 2016. The second specimen is plasticized according to modern German technology, which can be preserved for a long time.

During the pilot period, users do not have to pay service fees. Funding for implementation comes from funding from the European Commission and support from agencies implementing the pilot plan. It is known that the plan to connect two-wheeled electric vehicles with BRT fast buses in the planned pilot area has been reported to the City People’s Committee by the Hanoi Department of Transport and Communications. After being approved by the city, stakeholders will soon implement this model.

The group consists of eight first-year students: Chu Minh Nhan, Cao Khanh Gia Hy, Nguyen The Binh, Ho Huynh Gia Bao, Tran Duy Khang, Nguyen Duy, Ngo Ha Gia Bao and Mai Hoang Kim Son. The group made the fabrication under the guidance of three lecturers, Prof. Dr. Quan Thanh Tho (Deputy Dean of Faculty of Computer Science and Engineering), Dr. Le Thanh Long (lecturer of Faculty of Mechanical Engineering) and Dr. Vo Thanh Hang (Deputy Head of Faculty of Computer Science and Engineering). lecturer in the Department of Environment and Natural Resources). A group of students worked hard together to make a thermometer Dr. Vo Thanh Hang (female), Assoc. Prof. Dr. Quan Thanh Tho (shirt) and a group of students next to an automatic body temperature measuring device. Photo: NTCC Chu Minh Nhan, a member of the group, said that the group is currently completing a number of features such as the data entry table, the frame structure… according to the suggestions of the teachers and teachers. It is expected that in the middle or the end of June 2021, the group will complete the apparatus and put it into use at the school’s entrances. Compared with other machines on the market, the advantage of IoT-integrated automatic body temperature and hand washing machine is that it is programmed with IoT to recognize faces (check student IDs and faces) to remind you to wear a mask. voice. The device will automatically measure the body temperature and warn when the body temperature exceeds the normal range. Update data on user information and temperature of use, record information, when the user is using the machine… The machine also supports automatic hand washing with a sufficient amount of antiseptic solution. In particular, the data (temperature measurement results, entrance time, facial recognition images) will be stored and transmitted to the central server. Medical staff will easily access and retrieve data for control and tracing of suspected COVID-19 cases. Dr. Thanh Hang, instructor, said that the thermometer is a product developed by a community project and entered the top 10 of the soft skills class of the school’s international training program. After that, students continued to research and develop machine manufacturing, combined with smart internet usage features, to improve usage efficiency. According to Dr. Thanh Hang, the group has now registered a student scientific research project (start-up program) and manufactured according to the university’s order to use in the prevention of COVID-19 at the University of Science and Technology.
