With a favorable location and diverse natural and cultural resources, Phu Quoc city of Kien Giang province has immense potential for tourism development. Phu Quoc is one of the localities with the biggest number of tourist arrivals and the highest revenue from tourism in the Mekong Delta. However, due to the impact of the Covid-19 pandemic, Phu Quoc tourism faces many difficulties in implementing the pre-set plans. Using a systematic review of the literature to synthesize the information dealing with tourism resources, impacts of Covid-19 pandemic on tourism performance and recovery plans of local authorities, the article analyzes the potential and current status of tourism development of Phu Quoc. Interviews with researchers and travel agencies’ representatives also add some ideas to the proposals for the orientation of tourism development in the new context. Integration to regional and international market, promotion of regional interlinkage and travel demands and new trends of tourism are crucial factors recommended for the development of tourism on Phu Quoc island.

Since 2017, the United Nations has strengthened the economic sanctions on North Korea. Many countries have stopped trading with North Korea, causing the economic certain difficulties. China has become a trade and tourism partner that accounting for almost all of the country's foreign currency earning. That had gone on until the beginning of 2020 when North Korea locked its borders to avoid the Covid-19 epidemic. North Korea is essentially famous for having published a quite relatively little information about themselves and being nicknamed “The Hermit Kingdom” due theirs policies. Therefore, the article will analyze mirror data from countries, then compare it with the actual situation of North Korea to assess the reliability of the data. Moreover, providing information on transport routes that is major contributor to China-North Korea. Thereby, drawing comments on China-North Korea merchandise trade and tourism industry relationship in that stage and proving North Korean economic adaptation under International sanctions. The author also suggests polices to reach the North Korean development of self-reliance economics.

With the fast growth of the COVID-19 pandemic, in-silico studies based on the susceptible-infected-removed (SIR) epidemiological model are very critical to provide reliable predictions of the COVID-19 evolution that can effectively support governments to issue the right measures to prevent and control the pandemic. In this study, the evolution of the COVID-19 in the Binh Duong province is investigated using the SIR model implemented in R-Studio software, in which the homemade computer codes based on the SIR model are developed using R language to automatically detect the optimal parameters in the model, including the reproduction ratio R0, the infection coefficient β, and the recovery coefficient γ. The SIR predictions indicate that the number of new positive cases per day in the Binh Duong province is only 40 new cases by November 30, 2021, and the total number of new cases per day becomes zero by middle February 2021. Besides, the Binh Duong province only has 1126 infected cases by November 30, 2021, which reduces to 203 cases at the end of December 2021. Through the SIR results, the COVID-19 pandemic in the Binh Duong is predicted to be ended at the end of December 2021.

In the last days of 2019, when the whole world was waiting for the moment to enter a new decade, a strange kind of unexplained pneumonia appeared in Wuhan city, China. From the little information as well as attention initially, this epidemic has turned into a pandemic worldwide. The quick-fire coronavirus spread and the response of different countries to it highlight immediate concerns about public health and have a significant impact on the evolving world order and the values that underpin it. This pandemic is unprecedented in its capacity to take advantage of modern globalization, allowing for massive disease spread at a surprising speed. It can say that COVID-19 is an additional blow to the vision and practices of the globalization process that is already under strain. Using the qualitative methods research and conceptual approach, the article, on the one hand, tried to analyze the challenges that globalization is facing because of COVID-19. On the other hand, we want to affirm that globalization will still be an irreplaceable trend in the future.

This paper explores the pros and cons of using online setting for teaching and learning English comparing with in-class setting. Online setting is undergoing a fast transformation and becomes a widely promoted platform due to COVID-19 pandemic. By reviewing different studies on online teaching, this paper aims to provide readers a better understanding about online setting. These information would be useful in Vietnam where online class just has a medium used and short history comparing with other developed and developing countries, so online class in Vietnam may need adjust and consideration based on different culture and learner’s experience. This paper also give some suggestions in design of online learning for English languages to increase the learning effectiveness.

SARSCOV-2 virus and new strains have been spreading in most countries and regions around the world, the COVID-19 epidemic it causes has infected millions of people, the urgent need is to prevent their spread. On the market there are many types of hand wash equipment automatically spray disinfectant solution used with many different sensors and operating principles, but most are still using AC power. In this topic, we design automatic hand washing equipment by applying the transmitter and receiver principle of the moving infrared sensor circuit and delay relay circuit to detect someone appearing in the observation area, click activating the MP3 reader circuit plays the “5K” propaganda sound about Covid -19 disease prevention and the position sensor activates the mini-pump to spray the hand-washing gel within a certain detecting distance. We have conducted experiments and completed our projects with devices that use energy from solar cells, through charging circuits and storage batteries with the goal of using renewable energy, minimizing impact of the greenhouse effect.
