VIETNAMESE HIGH SCHOOL EFL TEACHERS’ PERCEPTIONS TOWARD ONLINE TEACHING UNDER THE IMPACT OF COVID-19

The coronavirus disease case, commonly known as Covid-19, has spread internationally since March 2020. Approximately 100 countries, including Vietnam, closed their schools due to a public health emergency, according to UNESCO. Due to the circumstance, teachers were forced to convert from in-person instruction to online instruction. In the context of Covid-19, this study investigated how EFL high school instructors felt about online English language education. A descriptive design and a mixed-methods approach were utilized in this investigation. Six EFL high school teachers in the Mekong Delta were interviewed for this study to get their perspectives. The findings demonstrated that the participants' opinions on the usefulness and simplicity of online instruction during the Covid-19 epidemic were overwhelmingly positive. Despite the challenges they encountered when conducting their online classes, the teachers were able to show the proper attitude toward using technology to teach. The pedagogical implications of online teaching and learning are also meant to encourage the development of innovative teaching strategies in the setting of high schools in the Vietnamese Mekong Delta.  Article visualizations

IMPACT OF THE EVFTA AGREEMENT: A STUDY ON VIETNAM'S EXPORTED GOODS

Abstract The research aims to assess the quantitative impact of the Vietnam-European Union Free Trade Agreement (EVFTA) on Vietnam's export growth to the EU market. The study employs quantitative analysis using the SMART model with data on export turnover and scenarios of tariff reduction to 0% when EVFTA takes effect. Based on the export turnover data and necessary parameters, the analysis results show an increase in Vietnam's exports to the EU market when EVFTA becomes effective. As a result, the research proposes some implications to promote Vietnam's export activities to the EU in the future

IMPLEMENT POLICIES ON TRAINING AND FOSTERING CADRES AND CIVIL SERVANTS OF KHMER IN THE MEKONG DELTA, VIETNAM

Cadres and civil servants who are ethnic Khmer people in the Mekong Delta have an essential position and role in implementing the Party's guidelines and guidelines, policies, and laws of the State to present with the people and directly manage society to achieve order, stability, and development. Cadres and civil servants who are ethnic Khmer people are the bridge between the Party, State, and the people, reflecting the people's legitimate thoughts and aspirations for the Party and State. Based on the method of document research, and secondary data, the paper outlines the characteristics of the Khmer people in the Mekong Delta; viewpoints and lines of the Party, policies, and laws of the State on training and retraining policies for cadres and civil servants who are ethnic Khmer people; On the basis of the actual situation of the policy, the thesis has proposed a number of solutions to improve the effectiveness of the policy on training and fostering cadres and civil servants who are ethnic Khmer people in the Mekong Delta.  Article visualizations

EVALUATION OF CITIZENS' SATISFACTION WITH THE QUALITY OF PUBLIC ADMINISTRATIVE SERVICES IN THE MEKONG DELTA, VIETNAM

Citizen satisfaction is one of the essential factors reflecting the quality of public administrative services provided by state administrative agencies. The study aims to assess citizens' satisfaction with the quality of public administrative services in the Mekong Delta, Vietnam. Research data were collected from survey results using questionnaires from 792 survey samples in the Mekong Delta, Vietnam. Research results have shown that citizens are satisfied with the quality of public administrative services in the Mekong Delta, Vietnam. At the same time, there are six factors affecting citizens' satisfaction with the quality of public administrative services, including (1) Reliability; (2) Service capacity of staff; (3) Service attitude of staff; (4) The service level of staff; (5) Infrastructure; (6) Administrative procedures. Research results show no difference in citizen satisfaction in gender, age and education groups. Besides, the survey area group has a difference in citizen satisfaction. The research results have theoretical and practical significance for public administration in Vietnam. From the research results, several contents are discussed and proposed to improve citizens' satisfaction with the quality of public administrative services in the Mekong Delta, Vietnam

Investigation of Sodium Manganese Oxide Nanowires Synthesized by Hydrothermal Method for Alkaline Ion Battery

Sodium Manganese Oxide (NaxMnO2) has attracted much attention as cathode materials for alkaline ion battery due to the ability of fast charge and discharge ion Na+, in particular in nanoscale. We report on the synthesis of NaxMnO2 nanowires via hydrothermal synthesis route from Mn2O3 and NaOH solution. The morphological observation indicates that the obtained Na0.44MnO2 nanowires with diameters of about 20-30 nm, length up to several micrometers were formed by this process. The electrochemical properties of fabricated materials were investigated by means of cyclic voltammetry technique and show that Sodium Manganese Oxide (NaxMnO2) is a promising material in the field of research and fabrication alkaline ion battery

Design and simulation of automotive radar for autonomous vehicles

Modern automobile technology is pushing towards maximizing road safety, connected vehicles, autonomous vehicles, etc. Automotive RADAR is core sensor technology used for ADAS (Advanced Driver Assistance Technology), ACC (Adaptive Cruise Control), AEB (Automatic Emergency Braking System), traffic assistance, parking aid, and obstacle/pedestrian detection. Despite being inexpensive, RADAR technology provides robust results in harsh conditions such as harsh weather, extreme temperature, darkness, etc. However, the performance of these systems depends on the position of the RADAR and its characteristics like frequency, beamwidth, and bandwidths. Moreover, the characterization of varied materials like layers of paint, polish, primer, or layer of rainwater needs to be analyzed. This performance can be predicted through real-time simulation using advanced FEM software like Altair FEKO&WinProp. These simulations can provide valuable insight into the performance of the system, allowing engineers to optimize the system for specific use cases. For example, simulation can be used to determine the optimal parameters of the RADAR system for a given application. This information can then be used to design and build a physical model or prototype that is optimized for the desired performance. These simulations play a prominent role in determining appropriate data collection and sensor fusion, which reduces the cost and time required for the development of a physical model or prototype. The continued growth and demand for advanced safety features in vehicles further highlight the importance of RADAR technology in modern automobile technology. By accurately characterizing the environment and simulating the system's behavior in real time, engineers can optimize RADAR systems for specific use cases, contributing to safer and more efficient driving experience

Spatiotemporal evolution of SARS-CoV-2 Alpha and Delta variants during large nationwide outbreak of COVID-19, Vietnam, 2021

We analyzed 1,303 SARS-CoV-2 whole-genome sequences from Vietnam, and found the Alpha and Delta variants were responsible for a large nationwide outbreak of COVID-19 in 2021. The Delta variant was confined to the AY.57 lineage and caused >1.7 million infections and >32,000 deaths. Viral transmission was strongly affected by nonpharmaceutical interventions
