This paper clarifies the work undertaken by public assistance caseworkers in Yamaguchi Prefecture by analyzing their weekly work diaries and comparing them with the work stipulated in the Public Assistance Act and the Social Welfare Act. The work of public assistance caseworkers was subdivided into 21 items. When the contents of the work were classified into the four categories of work stipulated in the Social Welfare Act, 44.6% of the work was made up of interviews; 24.5% was investigation; 47.9% was decision-making, and 1% was providing guidance. These findings indicate that public assistance caseworkers conduct interviews with those receiving assistance and with others connected with them, make decisions regarding whether to provide public assistance, and provide guidance according to the situation for the purpose of investigations that form the basis for the proper administration of public assistance. In addition, the ratio of the different aspects of their work indicates that there are only a few guidance tasks related to handling cases of fraud. Public assistance caseworkers have the heavy responsibility of having a high level of decision-making ability in deciding whether to provide public assistance as a physical manifestation of citizens’ right to life, based on the information obtained from investigations related to interviews with those receiving assistance. 　Furthermore, with regard to the discretionary power of public assistance caseworkers in carrying out their work, it was found that although there is no room for discretion in the application of the law in guaranteeing a minimum standard of living, as this is a legally mandated task, they do have discretion in promoting self-reliance because they implement self-reliance support programs that are tailored to the situation on the ground in individual welfare offices. In addition, although there is no room for discretion regarding how to allocate energy when dealing with applications for starting or changing assistance due to the time constraints in the process leading up to making a decision, it was found that discretion was given to caseworkers in cases where they were making visits to households receiving continuing assistance, as these were planned on a yearly and monthly basis and implemented systematically.

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.

This study investigated abuse to people with disabilities, considered "abuse to people with disabilities by employees of welfare facilities for people with disabilities" as described in each "Report on the Investigation Results" for the fiscal years 2015-2019, and considered the current situation and problems of abuse to them suggested by these reports. As a result, it became clear that intellectually disabled people are intensively abused, and that people in higher disable support categories and people with behavioral disorders (the terms used in the reports) are being increasingly abused.

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 topological reference system is a theory that allows the visualization of the effects of a ring structure on the energy stabilization of π-electron conjugated systems. In this study, the original paper was reconfigured to introduce the definition of the topological reference system and practical calculation method.

This special issue, Issues Related to Suo Kokufu, consists of the following: Kazumi Tateno’s Traffic around Ancient Suo, Makoto Sato’s Functions and Facilities of Suo Kokufu, Hiroyuki Kanegae’s Kunizonin and Their Duties in Suo Kokufu, Tomoyasu Kato’s Kokushikan in the Kokufu, Shigeru Watanabe’s Suokoku and the Political Arena in Late Antiquity - with a Focus on the Activities of Tamanooya, and Kenji Kurata’s Restoration and Analysis of Historical Landscapes Using GIS Platforms - the Case of Ancient Suo Kokufu. The issue summarizes the results of the five-year joint research project between Yamaguchi Prefectural University and Hofu City titled Comprehensive Research on Suo Kokufu - the Formative Process of City and Hofu. We expect that the findings we present in this special issue will significantly expand the literature findings on and analyses of the latest excavation results.

Suo-Oshima Town, Yamaguchi Prefectural University, and Suo-Oshima High School signed an agreement of comprehensive cooperation on April 28, 2021. Professor Mizutani was asked to be the representative researcher to begin the “Suo-Oshima High School Aloha Project 2021.” With this project as the starting point, a joint collaboration was carried out on the promotion of Hawaiian culture through design in Suo-Oshima Town. This paper will investigate the Hawaiian culture promotion plan with particular focus on aloha shirts. In addition, as a practical study of design, it will verify the results of the workshops on making Hawaiian shirts, the fashion show, and the design exchanges which took place online. Finally, future challenges were identified for the purpose of contributing to the branding of Suo-Oshima Town through Hawaiian culture promotion.

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.

The purpose of this research is to examine spatial expression in graphic design through the creation of works. We will attempt to expand the expression of graphic design by pursuing the spatiality of the work itself rather than designing for advertisement or packaging.
