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.

Microscopic observation is one of the most basic and important skills for experiments in biology classes from compulsory education through to higher education. Microscopic observation in biology can help us better understand the microstructures of organisms and convey notions of beauty and fascination regarding the detailed nature of the microworld, which we cannot observe through our unaided eyes. However, many lab classes were postponed for the summer break because it was difficult for the faculty to conduct lab classes using equipment such as microscopes for non-face-toface learning at the university in the beginning of the COVID-19 pandemic. Under this situation, we planned that students do the experiment at home using handmade microscope. Students could make a simple Leeuwenhoek microscope very easily and use to understand the principle of the microscope. A non-face-to-face class required students to take the initiative in learning, which led to a better understanding of the principles of microscopy. Hence, the future integration of this nonface-to-face learning using a handmade microscope into an existing face-to-face lab class will be very useful for the teaching of science, especially biology, at many schools by science teachers and researchers.

As one of the first British diplomats to be posted to Japan, Sir Ernest Satow (1843~1929) became a firsthand observer of the political situation in the country in the years immediately preceding the Meiji Restoration of 1868. Throughout his first posting in Japan (September 1862~February 1869) Satow kept a journal in which he recorded his experiences. Satow later edited this journal for publication as A Diplomat in Japan (henceforth, Diplomat ) published in 1921, many years after the events of the 1860s. The subtitle for the first edition of Diplomat was, ‘The inner history of the critical years in the evolution of Japan when the ports were opened and the monarchy restored, recorded by a diplomatist who took an active part in the events of the time, with an account of his personal experiences during that period.’ This study is an examination of Satow’s ‘personal experiences during that period’ relating to what he ate and drank, and the culinary hospitality he received. This paper will then briefly discuss what can be inferred about the eating habits of Westerners in bakumatsu Japan based on the evidence of Diplomat .

This paper illustrates the way in which the text mining approach, often used in marketing studies, can be used to study intercultural communication. Tourists’ comments about Miyajima in Hiroshima prefecture on Tripadvisor, a tourism website, have been analysed to reveal how Japanese tourists and English-speaking foreign tourists, including Americans, the British, and Australians, use a variety of expressions regarding their visit in their comments and advice. The results reveal both similarities and differences in the posted content, which seem to reflect the characteristics of the Japanese and English language and their communication style. Writers in English tend to use a variety of adjectives to express their thoughts in positive comments, describing their experience in-depth and giving advice directly. The readeroriented approach using the second-person pronoun ‘you’ and imperative forms are used when giving advice. American, British, and Australian writers sometimes express their positive comments differently. On the other hand, Japanese writers tend to write shorter comments and to use fewer adjectives than writers in English in their comments. These cultural and linguistic characteristics of tourists’ comments can be analysed to understand the different uses of language in intercultural communication and for non-native English writers to learn how to write comments on tourism in English.

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.

In 2020, global phenomena such as unprecedented scale forest fires, storms, melting glaciers, and dramatic declines in northern polar glaciers are very likely to be caused by climate change. By the middle of this century, it is becoming clear that it is not enough for Germany’s greenhouse gas emissions to be cut by 80% compared to 1990 levels. In December 2015, to meet the climate targets agreed in the Paris agreement, stricter cuts from Germany are required, limiting global temperature rises to an average of 2 ℃(better 1.5 ℃) compared to pre-industrial levels. With regard to the transition of Germany’s energy systems, this paper begins with a comprehensive model of the Germany power and thermal sector in future energy systems with a major contribution to renewable energy technologies. Based on REMod-D (Renewable Energy Model - Germany), the basic structure is summarized briefly. Then, we introduce some of the simulation results by REMod-D models by Philip et al. (2020). The aim is to assess the energy transition and the possibility of climate-neutral systems in Germany.

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.

In this study, we present a new method for estimating input coefficient matrix with deep learning. We use the data of prefectures of Japan as the training data. However, the data is small and is likely to cause overfitting. Therefore, we attempt to avoid the over-fitting by creating new data of virtual areas aggregating multiple prefectures. The approach is based on the concept of data augmentation. As a result of predicting the input coefficient matrix of Yamaguchi prefecture and Gujo city, we showed that the method using deep learning can estimate the matrix with more stable accuracy than RAS method for these areas.

Germany's energy transition (Energiewende) is a paradigm shift into a low-carbon and nuclear-free economy. As part of the European Union's climate neutralization drive, aiming to reduce greenhouse gases to net-zero by the middle of the century. Generous financial support for wind and solar power has boosted renewable energy to produce more electricity than fossil fuels for the first time in 2020. Germany's energy transition is not a policy shift after the Fukushima nuclear disaster, but a long-term process of policy making in response to public opinion and technological trends. Germany's energy transition is still underway and needs to be extended beyond the power supply. However, it may already be pushing more thoroughly through pricing and volume regulations, such as the European Emissions Trading Scheme (EU-ETS) and changes to the carbon tax, which provides incentives for changes to low-carbon technologies. This paper analyses Germany's energy transition and climate policy. The purpose of this paper is to clarify the actual conditions and issues of the reduction effects of greenhouse gas emissions, which are the main policy issues of the energy conversion policy that has been developed mainly on renewable energy for these 20 years.

There is a risk of longevity i.e., the self-funds after retirement may deplete before the end of life. What is needed after retirement is to spend out of self-funds in addition to public pensions while investing self-funds over lifetime without depleting. We analyze a safe withdrawal rate based on varying self-funded amounts every month due to fluctuation in the market. According to this method, there is no longevity risk that self-funds are depleted throughout lifetime.

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.

Taiwan is not a party to the Paris Agreement, but the impact of climate change on Taiwan is enough to be one. The Government of Taiwan has set a target of adjusting the power mix to 50% natural gas-fired, 30% coal-fired and 20% renewable energy by 2025, increasing the proportion of relatively low carbon emissions and renewable energy, and aiming to reduce GHG emissions as a climate change policy. One of the key aspects of Taiwan’s energy policy is to phase-out nuclear power generation by 2025, and to increase the share of renewable energy in the power supply configuration and reduce the use of coal-fired power. The phase-out of nuclear power plants was initially faster than the expansion of renewable energy, reducing CO2 emissions from electricity production as needed to a small amount. Nevertheless, since 2016, Taiwan has been evaluating the “energy transition” derived from Germany and is trying to decentralize its power supply using conventional large-scale, inflexible power generation systems.  With regard to coal-fired power plants, Taiwan will accelerate the improvement of air pollution facilities at existing coal-fired power plants and implement utilization management measures in order to match air quality. Gas-fired and green energy power supplies will be the mainstays of power supply, which is the power stabilization target, in order to maintain 15% of the supply reserve rate. The government needs to plan supply-side measures and implement various tasks to save energy and reduce carbon emission in order to reduce electricity demand. To build clean energy systems and healthy living conditions, to promote the development of new green energy industries, to promote green employment, realize the spirit of energy empowerment, promote energy democracy and justice. Going forward, the focus will be on overall system integration, where all power supplies can ensure a sufficient level of revenue. In this study, we will consider Taiwan’s climate change and energy policy since the Paris Agreement, and summarize the current situation and issues.

Retail investors, who are the majority traders in the Chinese stock market, cannot participate in off-line roadshows of IPO firms. Online roadshows are an important channel for them to learn about the situation of IPO firms. This study takes the IPO firms which are new-listed in Shenzhen Stock Exchange from 2010 to 2018 as the research subject, investigates the relationship between question-answers relevance in online roadshows and the first-day performance of IPO firms. According to the results, a high-level of question-answers relevance leads to a high first-day return and high liquidity. Furthermore, the additional analysis shows that the IPO firms with a high-level of question-answers relevance show stable long-term stock returns, on the contrary, the IPO firms with a low-level of question-answers relevance show the trends to decrease. Online roadshows could mitigate the information asymmetry between the investors and IPO firms, and play an important role in assessing firm values.

As climate change and various environmental pollution issues are becoming more serious, many countries are actively promoting energy transition. The Paris Agreement, adopted in 2015, is aimed at curbing the rise in global average temperatures to within 2℃ above pre-industrial levels and limiting temperature rises to 1.5℃ above pre-industrial levels. Taiwan is accelerating its path of energy transition to a "nuclear-free homeland" and “low-carbon economy” by phasing out all nuclear power generation in 2025 and imposing a legally binding goal of reducing coal-fired power generation from 47 percent to 26 percent. This paper investigates the impact of nuclear and coal power regulations on fuel mix CO2 emissions in the power sector by 2050 in Taiwan. Analysis is a future technology shift in the power sector called “Future Technology Transformations; FTT” for the power sector; Consider using the E3ME model linked to FTT: Power sub-model.
