大学陸上競技選手と一般学生を対象として、多回旋跳びを段階的に増やした４週間の縄跳びトレーニングが伸張－短縮サイクル（SSC）運動遂行能力と走跳能力に及ぼす影響を検討した。陸上選手は通常のトレーニングのみ行わせる群と、それに加えて縄跳びトレーニングを行わせる群に分けた。縄跳びはできる限り短い接地時間で行わせた。縄跳びトレーニングによって、陸上選手では最大連続跳躍（RJ）の跳躍高/接地時間の値（RJ-index値）および走跳種目の記録に変化はなかったが、同じ縄跳びトレーニングを行わせた一般学生ではRJ-index値と立ち幅跳びの記録が向上した。個人値を用いた検討の結果、90回/分の１回旋跳びでは２回旋跳びに比べて接地時間は長い傾向があったが跳躍高は高く、RJ-index値は同程度であった。縄跳びトレーニングによって陸上選手では効果はないが、一般学生のSSC運動遂行能力は向上する可能性があること、また、リズムが約90回/分の短い接地時間での１回旋跳びは多回旋跳びとともにSSC運動遂行能力を高めるトレーニング手段となる可能性が示唆された。

一九三六年に正宗白鳥と小林秀雄の間に「思想と実生活」論争が行われた。それは、晩年のトルストイの家出の理由が、妻のヒステリーを恐れた実生活にあるか、それとも彼の人類救済を含む文学思 想の存在にあるのか、という認識の食い違いから、「思想と実生活」の関係というより普遍的な争点 に発展していった。本稿は、この論争の対立構図を還元し、特に小林秀雄によって提示された「思想 と実生活の分離」という命題を通して、有島武郎が一九二〇年前後に悩まされた「思想と実生活」の 問題に遡行し、正宗・小林と比較しながら、彼の二元的世界観が独特な「愛」の哲学によって高い次 元での一元化へと変換しようとしたこと自体は、どのような意味を持っているのかを探ってみた。晩 年のトルストイの家出には、正宗と小林の対立だけでなく、有島の二元的世界観も反映されていた。 この論争に、有島を潜在的な参加者として入れてみると、「思想と実生活」の対立とその止揚がより 立体的に見えてくると思われる。, In 1936, a controversy on “thought and real life” took place between MASAMUNE Hakucho and KOBAYASHI Hideo. Was it because of his fear of his wife’s hysterical real life or was it because of his literary thought of trying to redeem humanity that Tolstoy ran away from home in his later years? The divergence in the understanding later developed into a more general debate topic of the relationship between thought and real life for MASAMUNE Hakucho and KOBAYASHI Hideo. The purpose of this paper is first to show the opposite structure of this controversy, and especially through the proposition of “separation of thought and real life” put forward by KOBAYASHI, to trace perplexity of “thought and reallife” troubling ARISHIMA Takeo around 1920. By comparing to MASAMUNE and KOBAYASHI, the paper also explores the significance of the effort ARISHIMA made when he attempted to transform his binary world view to a higher dimensional monism through his unique “love” philosophy. Tolstoy’s departure from home in his later years reflected not only the confrontation between MASAMUNE and KOBAYASHI, but also the binary world view of ARISHIMA. The inclusion of ARISHIMA as a potential participant in this controversy should give us more insights into the opposition and sublation of “thought and real life”.

本稿は有島武郎が一九二二年に発表した「宣言一つ」及び関連テキストを再読することを通して、「知識階級」と「第四階級」の階級移動の問題を再検討し、新たな理論的資源を援用して知識人の持っている「文化資本」の権力性と階級性を大正時代の文脈に沿いながら論じたものである。知識階級の啓蒙的暴力を反省することにおいても、過度な政治化と過度な脱政治化との間の選択においても、複数の価値的衝突と正義のアポリアに面する際の政治的実践においても、有島武郎にはまだ批判的可能性が内蔵されている。それは今日において政治思想の視点からも思考し続けるに値するものである。, The aim of this paper is to reconsider questions between intelligentsia and proletariat, and issue of intellectual representation put forward by ARISHIMA Takeo by reviewing his work An Announcement in 1922 and other relevant comments. By combining new theories, this paper would interpret the power and class character of cultural capital that intelligentsia had. It will emphasize that ARISHIMA Takeo had an impressive critical potential on three aspects: the reconsideration on the enlightenment violence of intelligentsia, the choice between excessive politicization or de-politicization, and the political practice when facing the conflicts among the different justice value, which is particularly relevant from the viewpoint of political thought today.

A recent breakthrough in cell therapy is expected to reverse the neurological sequelae of stroke, spinal cord injury, traumatic brain injury and so forth. In fact, various clinical trials concerning cell therapy for central nervous system (CNS) disease have been reported all over the world. Although some pioneer studies were conducted in China, accurate information was not always conveyed to Japan due to the language barrier. In our present article, we reported our systematic review of the scientific papers and the protocols about clinical trials concerning cell therapy for CNS disease in China. Moreover, we reported the regulatory framework for the stem cell research in China. It is noteworthy that we referred to not only English-based databases, but also Chinese-based databases. In conclusion, though some problems remain in China, we expect the acceleration of cell therapy for CNS disease in the future because of the new regulatory framework.

本研究は中国の大学における3、4年生の日本語を専攻とする学習者を研究対象者とし、中国で頻繁に使用されているアプリケーションWeChatの音声メッセージ機能を活用し、1ヶ月間で16回の発話活動を行った状況と結果について分析したものである。文字化されたデータを自由発話データやテーマ発表データに分けて分析し、話者の間にある交替反応時間の長い発話環境での発話活動の実態を明らかにし、WeChatを新たな練習ツールとして利用する可能性を示した。自由発話における相互作用的発話機能の出現率から見ると、WeChat環境は、話者が対面ではなく、発話の間に交替反応時間が長い発話環境であるため、考える時間が十分にあり、中断されずに話す内容を増やせ、まとまって発話することが可能である。また、テーマ発表におけるフィラーなどの出現の変化から得られた結果を見ると、WeChat環境は、学習者にとって間違いに対する不安が減少でき、気楽に話せる発話環境と言え、話す意欲の高くて積極的な学習者はWeChat環境を活用し、有効に練習できると考えられる。今後、WeChatを新しい発話練習ツールとして日本語教育に利用できることが示唆された。

Materials handling represents approximately 50 per cent of the operating costs for an open pit mine. This means an efficient operation of shovel-truck dispatching system is vital. In this paper, a practical dynamic simulation approach enhanced with Visual Basic for Applications (VBA) programming is proposed to optimize the trucks dispatch system for open pit mining planning. By presenting a case study in an open pit mine, it was found that by combining the simulation technique with the utilization of VBA programming, the transportation performance of trucks could be significantly improved, and a practical dispatching control table for meeting a mining plan can be created automatically.

The Guoshan Yao people who call themselves Mien are the most mobile of the Yao tribes （Yoshino 1994 : 94）. The Mien live mostly in southern Hunan Province, Guangdong Province, the Guangxi Zhuang Autonomous Region, Guizhou Province, and Yunnan Province. They also live extensively outside China, such as in Vietnam, Laos, Thailand and the mountainous area in northern Myanmar. This study deals primarily with the Mien settling in the Jianghua Yao Autonomous County of southern Hunan and the neighboring Gongcheng Yao Autonomous County of northeastern Guangxi. Studies on Mien ceremonial paintings are believed to have begun in the early 1980s, but extremely few documents have been published so far. Jacques Lemoine, a French ethnologist, is the only researcher who has written books on this subject. In his book Yao Ceremonial Paintings（1982）, he introduces approximately 200 religious paintings of the Yao people collected by him and eight others. He also briefly describes Mien rituals with photographs he took during field surveys of their communities in Thailand and Laos. Ceremonial paintings are classified into the following chapters : Fam Tsʼing, the Three Pure Ones ; The Jade Emperor and the Master of the Saints ; The Celestial Masters ; Tai Wai, the High Constable ; Hoi Fan, ʻThe Sea Bannerʼ ; The Governors of this World and the Waters ; The Governors of the Sky and the Underground ; The Lords of the Ten Tribunals of Hades ; The Marshals ; The Three Generals ; The Ancestors ; The Forebears ; The Dragon Bridge of the Great Tao ; The Enforcers of Fasting and Chastity ; Pʼan Huʼs Five Banners of Knights ; and Masks. In addition to the vast number of iconic images, Lemoine illustrates the characters of gods depicted in the paintings, such as their attire, postures and accessories. Unfortunately, these are mere brief explanations with no comparisons, analyses or examinations of the same religious paintings owned by the Mien residing in different areas. This study focuses on unexplored aspects of Lemoineʼs research to examine the content of Mien ceremonial paintings, while analyzing similarities and differences between the paintings in southern Hunan and northeastern Guangxi. Based on the findings, it further explores the characters of gods worshipped by the Mien, the influence of Taoism on ceremonial paintings, and the characteristics of the Mien reflected in the paintings., Departmental Bulletin Paper, 論文

The present study aims to develop an artificial pulsatile perfusion system (a phantom) for assessing mechanical properties of an artificial or the isolated human arteries. The system consists of a magnet pump, an inverter, a hand-made valve to produce pulsatile flow, a measurement tank to attach arteries and pressure sensors. The flow rate of the pump was controlled by the inverter with changing the driving frequency from 0 to 55Hz. A hand-made valve was designed to produce a pulsatile flow. An echo-ultrasonograph and a two-channel Doppler ultra-velocimeter were set to measure wall structure and displacement of the silicon and rubber tubes, and the flow velocity of the intramural water with a lycopodium powder, respectively. The peak flow rate corresponding to the contraction phase through the valve was much attenuated compared to the theoretically estimation value, but a pulsatile flow rate curve could be obtained. A pressure, a flow velocity and wall displacement wave forms in the sample tubes could be clearly measured and seemed to be reproducible. The mean values of the pressurestrain elastic modulus, the incremental elastic modulus, the Young modulus and the pulse wave velocity obtained under the peak intramural pressure of 60mmHg were 552kPa, 1860kPa, 1540kPa and 16.6m/s in silicon tube, and 308kPa, 758kPa, 682kPa and 12.4m/s in rubber tube, respectively. These values increased with increasing of the intramural pressure, and agreed with the values reported previously. From the above results it may conclude that the mechanical properties of the artificial or the isolated human arteries can be precisely estimated by using the phantom developed here and the measuring devices with echoultrasonograph and Doppler ultra-velocimeter.

Small signal gain of Solar-pumped laser system is measured. A Nd:YAG crystal and two Cr:Nd:YAG ceramics are used for this study. All experiments about mall signal gain is performed in the same day which is so sunny because stability of incident solar power is important for this measurement. Although its distribution should be axial symmetric, all results of laser media was not symmetric distribution. In addition, slope efficiency of each laser medium is measured by changing output coupling mirrors. Even though the distribution of small signal gain is not axial symmetry, laser output corresponds to calculated results using the distribution of small signal gain.
