We preliminarily surveyed the influence of COVID-19 on pregnancy, birth, and childcare. We used semi-structured interviews. We used text mining to analyze five participants who experienced pregnancy and childbirth before and during the COVID-19 pandemic. This study showed the following outcomes: (1) COVID-19 influenced familial support, social support, and birth. (2) Participants found it difficult to ask for support. (3) Participants needed social support for infection prevention at the preparation stage because they also cared for their children. (4) The birth affected the failure to share needs of the family and enhance the awareness of childbirth as a pregnant woman.

A multiple-choice questionnaire was administered to university students to investigate their positive changes during the coronavirus disease 2019 (COVID-19) pandemic. The data revealed that more than three-fourths of the students felt positive changes in relationships and values. Additionally, approximately half of the students felt positive changes in customs and behavior, while 20%–30% felt positive physical and mental vitality changes. Our findings suggest that it may be necessary for university students to notice their positive changes as being essential for growth during the COVID-19 pandemic.

An online questionnaire was administered to 143 university students to clarify their perception of the elderly and its related factors. Consequently, the elderly that formed the basis of the students’ perception regarding older adults were in the following order: “grandparents” > “the elderly in the community” ≥“the elderly in various media.” Furthermore, the students’ perception of the older adults was related to “frequent contact with grandparents,” “quarrel with grandparents,” “pleasant activity with the elderly in the community,” “training session offered by the elderly in the community,” “experience of being scolded by the elderly in the community,” “contents of various media for respect for the elderly,” and “contents of various media for the care of the elderly.” Our findings suggest that experiences with grandparents and older people in the community and various media may play an essential role in having a more positive perception of the elderly for students.

Based on a paper aimed to document the pioneering use of Blended Learning and Instructional Design published in March 2021, an attempt was made to improve one compulsory subject in the Postgraduate Schools of YPU. The goal of improving the class called ‘Quality of Life (QOL)’ was to show a model to be used at Postgraduate level for mostly adult learners so that they could access the class from their workplaces or homes. The construction of the whole class needed to be reviewed, instead of just utilizing an interactive online ICT tool. This paper also tries to present an idea for a certificate program based on the above QOL class. Yamaguchi Prefectural University promotes four educational principles, including “respect for human nature,” “emphasis on citizens’ perspectives,” “co-existence with the community,” and “response to globalization”. The focus on humanities is crystalized on the teaching subject, QOL, as mentioned above. ‘Quality of Life’ covers the examination of the quality of everyday life in today’s changing world to diverse life stages, and then into every type of lives in nature and around the globe. By placing the QOL class as the core and adding one or two classes, it is assumed that the certificate course could be started by connecting issues in local towns to innovative solutions in wider society.

Despite the various harmful effects caused by tourism, such as over tourism, there are few concrete measures to promote tourism and community development in an integrated manner. The background to this is that in tourism policies, indicators that are biased toward the evaluation of tourism exchange performance are set, and there is a lack of indicators that question the degree of involvement with the local community. On the other hand, in Europe and other countries, they contribute to the development of sustainable local communities by installing unified indicators (“ETIS” and “DIT-ACHIEV”) for advancing projects while considering tourism and regional formation from multiple perspectives. It should be a great example for Japanese local communities. The purpose of this study: Therefore, in this paper, we will analyze the factors that prevent the establishment and spread of indicators in the current situation, and analyze the method of setting indicators with high versatility based on the current situation. To accomplish these ends, the authors of this paper have tried to do questionnaire survey conducted by mail to 212 DMOs nationwide from November to December 2021. The conclusion of this paper: It was found; 1) Japanese DMOs lack the common purpose of "aiming for sustainable tourism", 2) Data collection for KPI is a burden for each DMO, 3) Relationship between DMOs and local residents is still weak, and in the first place, improvement in this point is desired.

The Ohuchinuri lacquer ware production area, which has a workshop centered on Yamaguchi City, became a designated production area under the National Traditional Industrial Promotion Law in 2001. This paper present the literature and materials to show the 100years succession of Ohuchinuri, which was compiled in the process of application. As a result, the merit of becoming a designated production area shows that the pride of the Ohuchinuri lacquer maker was cultivated and that the Ohuchi doll was selected as the target item. Interacting with lacquer ware specialists, the importance of urushi-e, which is represented by the Sesshu-bon tray of Enryuji Temple in the Edo period, was pointed out. This paper points out the importance of urushi-e as the basic technique of Ouchi lacquer ware.

From 2007 to 2021, Yamaguchi Prefectural University offered a seminar course called "Seminar in Community Collaboration" as a part of its general education curriculum. In this seminar, students worked together with local residents to solve regional issues. Among these projects, we will introduce the example of working together for 13 years on the local festival "Mori-sama Festival" with residents and high school students under a cooperation agreement with the high school. In addition, we worked together with the students who took the "Seminar in Community Collaboration" to make a proposal to support the survival of the festival after the abolition of the course due to a curriculum revision.

In this article, we describe an attempt to prepare teaching materials to efficiently process NDB open data. The teaching materials consist of explanations of NDB open data and instructions of data processing using Visual Basic for Applications (VBA), a programming language that can be used with the spreadsheet software Excel. In addition, the teaching materials allow students to understand the advantages of using VBA by comparing it to working with Excel worksheets. Finally, we asked them to solve VBA-related problems and confirmed their understanding of the teaching materials.

With the full-scale transition to online lectures in 2020 bue to the COVID-19 pandemic, along with the sudden widespread use of meeting applications by universities, everyone was thrown into a new world of communication in large groups via video conferencing. This technological leap has created a variety of problems for society, from the very small to the very large, and each problems requires a differen response. This paper focuses on camera usage during interactive online lectures, and aims to present one of the solutions to the issue of whether student cameras need to be on or off during lectures. Because the handling of camera images provoke ethical issues regarding student privacy, this paper also focuses not on solving the ethical issues conceptually, but by providing technical solutions to deal with this problem.

Text mining was used to analyze the TAT story used to determine the presence or absence of uncertainty motivation. Participants were 82 university students. The results show that: (1) Although there were few words specific to the stories judged to have uncertainty motivation, the words "microscope," "medicine," and "life" tended to be used in this story. (2) There were relatively many words that were used only in the stories without uncertainty motivation, such as the words "friend," "early," "end," "I," "fork," "walk," and "home". (3) No clear co-occurrence relationship could be found between the words.

As substances corresponding to annulenes in Y-aromatic compounds, tridentenes were proposed by the authors. In this description, by revision of existing papers, a discussion on the magic number of tridentenes, which corresponds to Hückel’s 4N+2 rule, and arguments regarding typhoon tridentene and cyclone tridentene, which are expected to have stereoselective inclusion forming ability, are presented.

The onion fly, Delia antiqua (Diptera: Anthomyiidae) spends hot summers and cold winters in the pupal stage. Pupal diapause is determined by the temperature and photoperiod of the larval stage and the temperature of the pupal stage. When the larvae were reared under various photoperiods at 25°C and the pupae were kept at 25°C after pupation, the rate of diapause tended to be slightly lower in photoperiods longer than 13 h in the light period. When the larvae and pupae were kept at 20°C, the rate of diapause was 80% or more in photoperiods with a light period shorter than 13 h. However, the rate of diapause gradually decreased during longer photoperiods, and when the light periods were longer than 16 h, it decreased to approximately 25%. The larvae were reared under light-dark conditions (12 h light: 12 h darkness) (LD 12: 12), 14: 10, 18: 6, and 24: 0 at 30, 25, and 20°C and the pupae were kept in continuous darkness (DD) at 30, 25, 20, and 15°C. When the larvae were reared at 30 and 25°C and the pupae were kept at 25°C, the rate of diapause was 15% or less regardless of the photoperiod. When the pupae were kept at 30 and 20°C, the rate of diapause was 50−75% and almost 100% at 15°C. When the larvae were reared under LD 14: 10, 16: 8, and 24: 0 at 20°C and the pupae were kept at 25°C, the rate of diapause was 15% or less. The rate of diapause the pupal temperature of 30°C was 50−75%, at 20°C was 30−65%, and at 15°C was almost 100%. When the larvae were reared under LD 12: 12 at 20°C, the rate of diapause at pupal temperature of 30°C was 50−75%, at 25°C was approximately 55%, and it was almost 100% at 15°C. When the larvae were reared under LD 12: 12 at 20°C and the pupae were kept for 4 weeks under DD at 20°C after pupation. And the pupae were transferred from 20°C to 7°C and then kept for 10, and 15 weeks at 7°C and then transferred to 25°C. When the pupae were kept for 10 weeks at 7C, adult emergence was concentrated the 11th day (the 109th day after pupation) after transition to 25°C, and on the 10th day (the 143th day). This indicates that diapause was broken by low temperatures (7°C). When pupae were kept under DD at 20°C after pupation, adult emergence started around 50 days after pupation and continued for more than 50 days thereafter. No concentration of emergence was observed even when the temperature was changed to 7°C after the emergence adults. This indicates that diapause was broken at 20°C. The larvae were reared under continuous light at 15°C and the pupae were kept under DD at 7°C after pupation and transferred to 25°C. When the pupae were kept at 7°C for 1 to 20 weeks, the longer the period of 7°C, the shorter the period from the transition to 25°C adult emergence. Adult emergence was concentrated when the 7°C period was 11 weeks or more, and the tendency was more pronounced as the 7°C period increased. When the larvae were reared under LD 12: 12 at 30 and 25°C and the pupae were kept under DD at 30, 25, 20, and 15°C, the rates of diapause were compared in 1981 and 2005. When the rates of diapause when the larvae were reared at 20°C, was compared between 1981, 2005, and 2006. When the larvae were reared at 30 and 25°C, the rate of diapause was lower in 1981 than in 2005, regardless of the temperature of the pupae. However, when the larvae were reared at 20°C, the rate of diapause was higher in 1981 than in 2005 and 2006, regardless of pupal temperature. These results indicated that many years of successive rearing influenced pupal diapause decisions. The most interesting finding was that in many years of successive rearing, the selective pressure for diapause changed with the rearing temperature of the larvae. This elucidation will be clarified by through genetic analysis in the future.
