This is the essay about Soseki Natsume's stepfather, Shigekazu Nakane. In December 1895, Soseki-his real name was Kin-nosuke Natsume-met Kyoko Nakane in an arranged marriage meeting at the official residence of the Chief Secretary of the House of Peers in Uchisaiwaicho, Tokyo. Her father Shigekazu had hald position of Chief Secretary of the House of Peers since February the previous year. He was at the height of his career.As Soseki described in "Michikusa" (1915), when He returned from England in 1903, Nakane was extremely impoverished and could not afford even an overcoat. He had no work and had heavy debts from a big loss which he had suffered on the stock market.Soseki had a bad relationship with his stepfather. He did not even attend his funeral when he died in 1906. But Soseki was more or less under the influence of Nakane.Basic information on Nakane "Soseki no Omoide (The memory of Soseki)" which was dictated by Kyoko Natsume and written by Yuzuru Matsuoka, but it does not tell much about him. This essay made a thorough investigation about him.In 1851, Nakane was born at the edo-hantei (residence maintained by a daimyo in Edo) of Fukuyama-han at Nishikata-machi, Tokyo. At the time of the Meiji restoration (1868), his family moved to Fukuyama in Hiroshima Pref.. Fukuyama-han ran schools named Seishikan in both Edo and Fukuyama. This essay reports the education Nakane received at both schools.Second, Nakane enrolled in the Igakko (now the University of Tokyo Faculty of Medicine,). However, his purpose was not to be a doctor but to study German. This essay describes about the medical education and German language education at the school, and his life in the dormitory.Finally, Nakane left the Igakko after two years and worked for Tokyo Shojakukan (now the National Diet Library) from 1875 to 1877. The essay conjectures about Nakane's work here.Investigating Nakane's life provides meaningful study of a man who lived in the Meiji era.

明治44年に建設された鉄筋コンクリートアーチ橋(石川橋)の解体調査にて得られた主鉄筋、配力鉄筋およびエキスパンドメタルの腐食性状、力学的性質、化学成分および金属組織の特徴を調べた。その結果、主鉄筋の強度規格は現在のSR235に相当するものであるが、鉄筋の伸びは現在のものよりもかなり大きいことが判明した。また、鉄筋の化学成分および金属組織に関しても興味深い知見が得られた。鉄筋の各種分析の結果に基づいて、当時の鉄筋の製造方法や製造地(国産または外国産)、鉄筋の腐食性状との関連性について考察している。

Of late, the term “boundary crossing,” i.e., conducting learning activities beyond the boundaries of organizations and workplaces, such as workshops and volunteer activities, has been drawing the attention of practitioners and researchers. Boundary crossing provides opportunities to acquire knowledge and skill unavailable at routine workplaces. It also facilitates obtaining new perspectives and thoughts. However, the concept of boundary crossing is not matured and lacks a firm consensus among researchers as they perceive the term “boundary” differently. While such differences are allowed, we should nonetheless clarify and recognize the difference between the perspectives on boundary crossing for developing the boundary crossing theory. Our review of the literature on boundary crossing identified two perspectives. Some works focus on the physical or institutional boundary between organizations, workplaces, and so on, while others focus on the heterogeneity of situation/context between workplaces. Furthermore, in addition to heterogeneity, the homogeneity of context shared by people engaged in boundary crossing facilitates their learning. Both heterogeneity and homogeneity of context contribute toward learning in different manners.

カメラを利用した文書や書籍情報のメモが日常的に利用されるようになった。撮影される画像は、対象の正面から撮影されるとは限らず、背景など不要な情報も含む。必要情報を記録するため、用紙領域を投影変換で引き伸ばし、画像情報の可読性を向上させる。しかしこの手法では、撮影対象が平面である必要があり、曲面画像では適用が容易ではない。そこで、本研究では対象の曲面を推定し平面展開を行う手法を提案する。

An outline of the acute effects of the Hiroshima and Nagasaki atomic bombs are summarized, based on documentary records. Acute injuries caused by the atomic bombs have been classified as thermal, mechanical, and radiation injuries. Combinations of these were most common. Many died from the immediate effects of blast and burns, but individuals often succumbed to trauma or burns before the radiation syndrome developed. Many more would have died from irradiation, had they been saved from the effects of trauma or burns. Nearly all who died within 10 weeks had signs suggestive of radiation injuries. Remarkable variation in sensitivity of body tissues to ionizing radiation was apparent. Radiation-induced bone marrow depletion was the most critical damage leading to death. In these instances, leukopenia and thrombocytopenia, and subsequent infections and hemorrhagic tendencies were the main causes of death. The clinical symptoms and signs of radiation injuries; the RBE of the atomic bomb neutrons for acute effects; and the effects of irradiation on spermatogenesis are also discussed.

トキソプラズマは世界人口の3分の1のヒトに感染しており、様々な精神疾患や神経疾患の発症リスクになることが推測されている。しかし、本原虫感染が精神疾患の発症や行動異常に至るメカニズムは解明されていない。そこで本研究では、宿主中枢神経系を支配するトキソプラズマ由来ブレインマニピュレーターの解明を目的とした。脳機能に関与する宿主シグナルに影響を与える原虫分子として、TgGRAIを見出した。TgGRAIはNFkBのシグナルの活性化に関与し、TgGRAI欠損原虫株を用いたマウス行動測定の実験によりTgGRAIの恐怖記憶の固定への関与が示唆された。本研究により、脳機能を改変する原虫因子の存在が示唆された。

本論は朱子『四書章句集注』の解説書、いわゆる四書疏釈書が南宋で登場したその要因を考察した。宋代の経書注釈書の特徴は「議論」形式であるのに対し、『四書集注』は簡略を宗とする「訓詁」を重んじた。そのため該書は読者には理解が難しく、朱子は口頭での解説を積極的に行い、その結果多くの語録が残された。四書疏釈書はそのような語録を引用した書物であるため、朱子の意に反し「議論」形式に逆戻りしたものである。一方、経書を言葉で論理的に説明する方法を批判した陸象山も、自説拡大のためには時に多言を費やし、門人達も語録を編纂するなど師の言葉を多く残そうと務めた。しかし陸学派は朱子学との対抗上、「文字言語」を用いない学問として自己規定することで、自派の純化を図ったが、その勢力は朱子学に及ばなくなっていった。つまり、知識人の底辺が拡大した南宋社会にあって、大量に生み出された初学者たちは、言葉による丁寧な解説がなければ理解できず、四書疏釈書はそのような人々の需要に応じて登場したのである。The second section addresses the chief causes of the appearance of the Collective Commentaries. Because Zhu Xi made efforts to reduce the number of words in Sishu zhangju jizhu, he conversely became concerned that readers would misunderstand his thought. He wrote Sishu huowen 四書或問 in order to ease these concerns and carefully explained either orally or by means of his letters the gist to novices who did comprehend this work. These were then compiled as the Zhuzi yulei 朱子語類and the Zhuzi wenji 朱子文集. In other words, the Sishu zhangju jizhu commentary was difficult to comprehend without reference to the many other works of Zhu Xi. The Collective Commentaries are works based on many citations from the Zhuzi yulei or Zhuzi wenji etc. and thus without exploring the many works of Zhu Xi, one could learn the important points of his thought. Therefore, considering the commentarial tradition in the Song dynasty, the Collective Commentaries were writings that reverted to "discussion studies." They became annotations for annotations, which Zhu Xi had criticized. But why did such books become widespread despite Zhu Xi's intentions? This comes down to the fact of the demand for them after the death of Zhu Xi and his disciples. But this was thought by some to be a contradiction between, on the one hand, the idea of Neo-Confucians who insisted on the limitations of words in attaining experiential learning that would transcend comprehension by language to realize the way of saintly masters and the idea that one must use many words (language) to spread the master's thought. In order to analyze this contradiction, the third section focuses on the scholarly tradition of Lu Xiangshan 陸象山, who was an opponent of Zhu Xi and who most severely confronted this contradiction. As is well known, Lu Xiangshan criticized word-by-word interpretation (xungu) of the Classics and verbose logical explanation, and he did not leave many writings behind. Yet, he logically refuted Zhu Xi's interpretation of words in debate and was devoted to spreading this through the medium of letters. In addition, after Lu Xiangshan's death, his disciples strove to preserve as many of his words as possible, compiling collections of his writings and his analects. However, such a media strategy by the scholars in the tradition of Lu Xiangshan obviously went against his teachings, and in competing with the scholars in the tradition of Zhu Xi, they were unable to expand as a school or to write new books due to their self-discipline and effort to purify themselves as a school without "written language". In short, the scholars of the Lu Xiangshan school abandoned the way of compiling writings that the scholars of Zhu xi school had done in producing the Collective Commentaries. As a result, their influence never equaled that of the followers of Zhu Xi. Given the above argument, it was novices who could not comprehend Zhu Xi's Sishu zhangju jizhu who first called for the Collective Commentaries. The Southern Song is said to be an era when the bottom rung of the intellectual class expanded. During such a period, a considerable number of novices whether they were scholars of the tradition of Zhu Xi or that of Lu Xiangshan, could not comprehend the teachings well unless clear explanations were provided. Accordingly, the scholars of Zhu Xi's school responded to such demands with the Collective Commentaries and thereby increased the number of students in their school. In contrast, it was likely the case that the scholars of Lu Xiangshan's school failed to take in new disciples due to their loyalty to the teachings of their teacher.
