All Data

Today, big data can be easily obtained in our daily lives. As a result, keywords such as data science and machine learning are no longer new. Universities, private companies, and government agencies have established departments and faculties related to data science, and various educational programs are being developed. The implementation of data science education for liberal arts at regional public universities is an urgent national issue to be identified and solutions to be proposed. Yamaguchi Prefectural University started a lecture course called Introduction to Data Science for all first-year students in FY2022 with the aim of acquiring data science backgrounds. In this paper, we examine the state of data science education for students in the humanities by using data on the submission status of assignments given to students in this course in FY 2022. The results showed the possibility of visualizing the degree of difficulty that students in the humanities, who are taking data science education for the first time, experience during data analysis exercises and the degree of their positive attitude toward the assignments.

Research on the Ouchi clan in the Late Middle Ages has been very active in recent years. However, there are few related studies on the actual activities of the Ouchi clan from ancient times to the early medieval period, and few areas have been elucidated. In this paper, therefore, we analyze the actual activities of the Ouchi clan in their early period by collecting fragmentary related historical documents dating back to the stage when they were called Tatara clan. As a result, it became clear how they expanded their power based on their activities in the central political world in the late antiquity, after the stage when they were active as provincial officials in Suo Province.

This paper is part of the study “Discourse Under Crisis.” In the context of this study, “Discourse Under Crisis” refers to verse or prose produced or utterances spoken under situations of crisis. The subject of discourse, that is, the authors of the prose or verse or the speakers, cannot avoid these situations, not being afforded the option to refuse． This paper explorers utterances of Confucius and his disciples, utterances of intellectuals in the Hanfeizi 韓非子, songs in the Chuci 楚辭, and pre-Qin 先秦 songs besides those of the Shijing 詩經 and Chuci 楚辭．

1)The verses of the Komai contained in the newly discovered Horeki Namekawa script 'Enzatsu-rui' match many of those contained in the Hamada script that was handed down to Chofu. 2)The Komai depicts a man and woman with shaved hair drinking sake together and praying to the Buddha in prayer. It is also a pun on the verses of the Noh play “Tamura”. 3)Kyogen “Rokunin-so” is recognized for its idea of wishing for a future life (becoming a Buddhist ascetic) with the act of shaving as a prank. It inherited the framework of the tale of a drunken becoming a monk. Based on the premise of an ending that makes use of this framework, the idea of adding a drinking scene accompanied by a Komai was conceived in the Horeki Namekawa version. 4)At the end of Horeki Namekawa version “Rokunin-so”, there is a mixture of the medieval elements inherited by this work (becoming a priest with mischief as a trigger) and its development in the Edo period (a reconciliation that did not lead to being a priest).

This article explores the relationship between media and politics during the war between Japan and China through articles published in “Style” by Uno Chiyo in 1936 . Uno declared this magazine was going to be “a fun magazine”, and would not cover comprehensive political issues. However, following the outbreak of the Japan-China war in 1937 , war-related articles appeared, but later suppressed. Eventually, Uno decided that the magazine adopt a governmental policy. However, “Style” did not become war time magazine. This article examines the reason for this.

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.
