The research finds that Chinese language courses have achieved a high level of popularity in Japanese higher education, with a large overall scale of education. However, there is a significant imbalance in the development of Chinese language education between different universities and regions. In terms of faculty, Japanese universities have made notable improvements, particularly with a relatively sufficient number of native Chinese-speaking teachers, meeting the demand for students to engage with foreign instructors. Regarding the talent cultivation model, Chinese language programs in Japanese universities emphasize phased training, with a distinctive model of "consolidating the foundation in the lower grades and focusing on research in the higher grades." As for textbooks, there is a wide variety of Chinese language textbooks available in Japan, with beginner-level and comprehensive textbooks being the most common. However, the number of widely-used textbooks is limited, and noticeable differences in textbook selection exist across universities, with most universities still lacking a unified textbook system. 2026-03-30T15:00:00Z http://hdl.handle.net/11133/4590 タイトル: 矢作川水系などにおけるヒメドロムシ科の生息状況 著者: 石川, 進一朗; 大島, 友樹; 内田, 臣一 抄録: In the Yahagi River, multiple dam constructions and flood-control operations are thought to have reduced riverbed disturbance in the middle reaches, causing various abnormalities in aquatic organisms. The main objective of this study was to identify species of the family Elmidae (Insecta, Coleoptera) that can serve as indicators of riverbed disturbance by examining their distribution and habitats, and to provide baseline data for evaluating riverbed disturbance in future projects such as the planned sediment bypass tunnel and sediment replenishment experiments. From 2023 to 2025, time-constrained sampling, quantitative sampling, hyporheic excavation sampling, and light-trap sampling were conducted in the Yahagi River system and nearby rivers, Honshu, Japan. In addition, specimens collected between 2001 and 2023 were examined. As a result, a total of 23 species in 13 genera were collected, including five endangered species belonging to five genera. Many species were widely distributed within the Yahagi River system; however, some were restricted to downstream areas, while others were limited to small tributaries. One species showing a highly localized distribution in relation to dams was Zaitzevia nitida, which was collected only upstream of Yahagi Dam. Based on this distribution pattern and comparisons with the Nagara River system, Zaitzevia nitida is considered to prefer habitats with strong riverbed disturbance. In hyporheic excavation sampling, larvae of Stenelmis vulgaris, Ordobrevia gotoi, Optioservus spp., Neoriohelmis kurosawai, and Zaitzevia spp. were relatively abundant or were collected only by this method compared with standard benthic sampling on the riverbed. These results suggest that the larvae of these taxa are hyporheic invertebrates inhabiting interstitial spaces within riverbed sediments. In the Yahagi River system, the five endangered species were found across a wide range of both the main channel and tributaries. Light-trap sampling often attracted some species that are unlikely to inhabit nearby rivers. Therefore, light trapping is inferred to be less suitable for investigating species distribution and habitat compared with sampling methods conducted directly within river water. 2026-03-30T15:00:00Z http://hdl.handle.net/11133/4588 タイトル: 日本社会における「引揚者」に関する認識の考察 : 行政側と当事者側の相互交渉を手がかりに 著者: 劉, 罡 抄録: This paper examines how “repatriates” (hikiagesha) were perceived and treated in the early postwar years through an analysis of government policies and the responses of the repatriates themselves. Focusing on the implementation of repatriation policies as part of Japan’s postwar reconstruction, it clarifies how the state sought to reintegrate large numbers of returnees from former colonies into society while categorizing them administratively as “recipients of relief.” At the same time, many repatriates rejected this passive label and emphasized their contributions to the empire, demanding public recognition as competent and deserving citizens. By juxtaposing the administrative recognition of repatriates with the self-understandings of the returnees, this study reveals the dynamics between state and individual in early postwar Japan and highlights the tensions surrounding notions of welfare, merit, and responsibility. It also points to the risk that emphasizing victimhood or contribution may obscure the negative legacy of Japan’s colonial rule． 2026-03-30T15:00:00Z
