For Chinese people, study abroad is an important matter. During the COVID-19 pandemic, many countries implemented travel regulation policies. Except for the early part of 2020, however, long term residents, including international students, were allowed to enter Japan. Despite the COVID pandemic, some of the degree program students entered Japan from abroad. In addition, as soon as the international travel regulations ended, a huge number of non-degree students including kenkyusei（ research students） and language program students rushed to Japan.

The purpose of this study was to experimentally examine the effects of wearing masks and sunglasses on the impression rating of a person in a COVID-19 pandemic environment. In this study, two groups were set up for the degree of familiarity with the person of the stimulus, one with a first meeting and the other with a four-year personal relationship. The experiment was conducted with first-year and fourth-year undergraduates, and the results of impression ratings using the SD method showed that for females meeting for the first time, wearing a mask decreased familiarity with the stimulus more than with the standard stimulus. For males in the first meeting group, wearing sunglasses decreased forcefulness. In the group with higher intimacy, these impressions were not reduced. Cluster analysis using the participants' consciousness of their public appearance as the dependent variable revealed two clusters, one for the high and one for the low level of awareness of others. Comparing the two groups' ratings of men who met for the first time, the cluster with low awareness of others showed a decrease in forcefulness due to the wearing of the mask, whereas the cluster with high awareness of others showed no decrease in forcefulness.

During the COVID time, international students could not enter Japan easily. Until March 2022, regulation and deregulation for degree course students often changed in Japan. Like tourists, furthermore, non-degree shorter student mobility opened later. For exchange, research, and other short course students, they needed to wait until October 2022 to come to Japan.

In the 2000s, English-Medium Instruction (EMI) in non-English countries developed worldwide. Japan is one of these countries and the number of English-based students who cannot utilize Japanese language increased. Some of the Japanese universities offer dormitories for international students, who can gradually get used to learning the Japanese way of life after they arrive in Japan. Some of the universities also offer cultural exchange programs for EMI students. However, due to the COVID-19, the situation has changed.

To minimize the impact of the COVID-19 pandemic, the Japanese government regulated the mobility of international visitors including students. Before March 2020, international students could enter Japan without restriction. During October and November 2020, a limited number of international students entered Japan with expensive air fares and a 14-day quarantine. However, except these months, many students, especially newly enrolled ones, could not enter Japan.

This paper examines : (1) the medical governance of infectious diseases in Taiwan based on the experience of infectious diseases and the background of medical governance reform, (2) the role of big data and digital technology in infectious disease control, (3) medical strategy and non-pharmaceutical intervention, and (4) socio-political viewpoints regarding the COVID-19 pandemic in Taiwan. It will be possible to confirm that Taiwan's non-pharmaceutical intervention strategies, including mask wearing, AHH practices, quarantine / quarantine, travel restrictions and the implementation of social distancing, are increasing the effectiveness of preventive measures during the COVID-19 pandemic. In addition, the combination of extensive risk communication highlighting the importance of early border control, government leadership and preventive action has prevented Taiwan from locking down. These comprehensive preventive measures against COVID-19 in 2020 are more efficient and effective than those implemented during SARS in 2003, as well as immunoassay responses. In addition, democracy provided institutional support for vibrant civil society and synergies between state and civil society, strengthened the legitimacy of Taiwan's crisis governance, and enhanced voluntary compliance among citizens.

Due to the COVID-19, many countries including Japan have reinforced regulations at the borders. As many international students could not enter Japan due to the COVID-19 pandemic, some universities offered online education services as an alternate. On the other hand, since April 2020, many of international student livening in Japan have not been able to go back to their countries.

This research aims to examine the relationship between political connections and bank performance during the COVID-19 pandemic in Indonesia, with data sample comprising banks listed on the Indonesia Stock Exchange （IDX）. The study employed a panel data linear regression and found an insignificant positive influence of political connections on banks' profitability. However, the result also indicates marginally lower profitability in politically connected banks compared to non-connected peers, and the event-study methodology reveals the tendency for affiliated banks to obtain substantial negative abnormal returns during the pandemic. Therefore, there is a negative effect of COVID-19 on stock performance of politically connected banks.
