A new driving mechanism for holonomic omni-directional mobile robots is designed, which enables 3 DoF (degrees of freedom) motion control in two dimensional space by three correspondent actuators in a decoupled manner without redundancy. The kinematics of the omni-directional mobile robot is also analyzed to prove that driving motion by the actuators is decoupled by the developed mechanism into 3 DoF motion of the robot. A prototype of the omni-directional mobile robot with the driving mechanism is developed including a parallel link suspension mechanism. Finally, the performance of the prototype robot is shown through experimental results, by which the working of the designed mechanism is verified.

電気は現代都市の人々にとって必要不可欠なエネルギーである。これまで電気事業の成立や技術的進展に関する研究は多く存在していたが、電気を使用する需要者の視点と実際に電気を消費する都市や建築の視点から検討した研究は稀であった。本研究はそのような問題意識を背景に、明治中期、我が国最初の電気事業者である東京電燈会社が東京市内において行なっていた電気供給と配電網、そしてその顧客であった需要者について、東京電燈会社の営業に関する文書史料を中心に復元・分析を行いその実態について明らかにしたものである。東京市内における電気供給には大口の需要者が市内各所に存在し、電気を要求する用途や機能も多岐にわたっていたことを明らかにし、そしてそれらの需要が配電網建設の要因となっていたことを示した。

Polyunsaturated fatty acids (PUFAs), including arachidonic acid (AA), docosahexaenoic acid (DHA), and eicosapentaenoic acid (EPA), are metabolized to various lipid mediators. The profile of these lipid metabolites excreted into the urine reflects inflammatory state of the body and disease conditions. In this study, we quantified 156 types of lipids in urine samples of dogs with splenic mass, using liquid chromatography-tandem mass spectrometry. We found that metabolites of prostaglandin (PG) E2, F2α, and D2, 8-iso-PGF3α, lyso-platelet activating factor, and 14,15-leukotrien C4 significantly increased in urine samples of dogs with splenic mass compared to that of healthy dogs. These observations may reflect general inflammatory responses and will help better understanding of the canine splenic mass.

免疫抑制薬内服患者への生ワクチン接種は添付文書上では禁忌とされている。しかしながら,免疫抑制薬内服患者はウイルス感染症で致命的となるリスクが高く,接種が望ましいという意見もあり,予防接種ガイドラインでは禁忌にはなっていない。今回われわれは,免疫抑制薬内服中で,麻疹・風疹・水痘・おたふくかぜについて酵素抗体法で (-) か (±) を示した腎疾患または膠原病患者に,当院倫理委員会承認後に患者毎に十分な説明を行い,生ワクチン接種を行い,抗体獲得率と有害事象について前向きに検討した。40名 (1~24歳) に,55接種 (MRワクチン22接種,水痘ワクチン18接種,おたふくかぜワクチン15接種) 施行した。抗体獲得率は,麻疹 (90%) と風疹 (93%) は高く,水痘 (44%) およびおたふくかぜ (43%) は低かった。2名に発熱,1名に発疹,1名にネフローゼの再発を認めたが,重篤な有害事象はなかった。免疫抑制薬内服中でも生ワクチン接種が有効である可能性が示唆された。

Nearly 60 primate species consume fungi as a part of their diet, where some species are heavily dependent on fungi, while others use them as minor food resources. Three methods have been used to study mycophagy (fungus-eating behavior) among primates: stomach content analysis, direct observation, and fecal analysis. Direct observation is the most widely used but provides only limited information regarding fungi species eaten by animals. DNA analysis or stable isotope analysis can complement such behavioral data to reveal new insights into mycophagy. Fungi play an important role in maintaining healthy forest by forming mycorrhiza with plant species. Mycophagous primates disperse fugal spores therefore might also contribute to the forest ecosystems. Regardless of their potential as spore dispersers, far fewer studies focus on primates compared with those on other mycophagous mammals such as rodents and marsupials. Studies show that primates generally consume above-ground fungi, while rodents and marsupials use subterranean truffles. Considering the facts that some terrestrial fungi are highly poisonous and that primates build a food repertoire based on feeding experiences, we are confronted with a question of whether they learn how to avoid poisonous fungi. New perspectives and approaches will allow us to explore the animal-fungus relationship in the ecosystem.

日本古来の浮世絵は,最も広く世界に行き渡った絵画形式であり,西洋文化に対する芸術的衝撃,特に多くの印象派の画家たちに与えた影響は“ジャポニズム”と言われる文化現象として知られている.1823年ごろに刷られた葛飾北斎の浮世絵“四日市”の赤色の着色料(R1~R3)と黄色の着色料(Y1~Y3),そして1821年ごろに刷られた五渡亭国貞の浮世絵“木母寺暮雪”の青色の着色料(B1~B3)について,それらの非破壊分析を光ファイバーを用いる三次元スペクトル法によって実施した.色刷り標準試料のそれぞれと三次元蛍光スペクトルの等高線図を比較した結果,赤色の着色料はベニバナの花弁から得られた染料“サフラワー”,黄色の着色料はウコンの根から得られた染料“ターメリック”,そして青色の染料は藍の葉から得られた染料“インジゴチン”であることが明らかとなった.

After the war, Japanese universities were reorganized into an institution not only for prosecuting academic researches as before but also for giving the people higher education in order to bring up “citizens”, and the number of universities has remarkably increased as compared with prewar days. In particular, recent economic development of our country has brought the growing attention of the people to university and the growing number of high school graduates who go on to universities. This tendency is also under the influence of the constitutional guarantee of the right to receive education. Likewise, the government has adopted, as one of its main policies, the policy of promoting the scientific technique and cultivating the people's ability, so that the problems of university system and education have often aroused public attention and discussion. Under such social condition, a matter which is always and hotly discussed is “university autonomy”.“University autonomy” in Japan had developed as a “custom” at the prewar Imperial Universities, the basic idea of which gave the faculty meeting an autonomy as to its human affairs, so as to maintain freedom of research. But after the Taisho era, when reformative thoughts such as socialism developed, the government authority hand in hand with the militarists exerted pressure upon the thoughts and opinions of progressive scholars, and by so doing frequently violated “university autonomy” as well as “academic freedom”.Through such experience before the war, we acquired after the war the constitutional guarantee of “academic freedom” and legal guarantee for the university's control over the human affairs of its teaching staff. However, “university autonomy” remains to be and is prevailingly considered to be a “custom” which has been practiced from the prewar days.Now, what is the reason why many troubles have happened in succession over this “university autonomy”, in spite of the constitutional guarantee of “academic freedom” and partial legal guarantee of “university autonomy”? It is worthy of discussion. Although many reasons may be pointed out, the author thinks the main reason may be found in the fact that the “university autonomy” has seldom become an object of scientific study because it has been a “custom” in the exact meaning, and that we have lacked in historical studying about the “Imperial Universities” which established the “custom”.On this hypothesis, the author discussed the development of the thought and custom of “university autonomy” in Japan before the war and the historical function of the Imperial Universities as the source of such thought and custom. The summary of the article is as follows.Section I. To make out the meaning and the background of the subject, the author explains the transition from the constitution and the underlying principle of it under the prewar Meiji Constitution to those under the postwar Constitution of Japan, and the difference of the constitutional guarantee and treatment of “academic freedom” and “university autonomy” under those two Constitutions.Section II. The birth of the University of Tokyo as the first modern university in Japan; its reorganization into the “Imperial University” by the first Education Minister, Arinori Mori, in 1886 when the Ordinance of Imperial University and other school ordinances were framed; the process in which this “Tokyo Imperial University” came to be established as a model to subsequent Japanese universities and university institution; these matters are sketched.
