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.

We report the case of a 48-year-old woman with relapsed B-lineage acute lymphoblastic leukemia(B-ALL)following cord blood transplantation, in which leukemic cell CD22 antigens became negative after a single administration of inotuzumab ozogamicin(InO).At relapse, a major part of leukemic cells expressed CD19 and CD22 antigens, however some leukemic cells were negative for CD22. As treatment with blinatumomab proved ineffective, InO therapy was subsequently initiated

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.
