The purpose of this study was to identify the angles of the shoulder complex which consist of glenohumeral joint, scapulothracic joint, and thoracic joint at the maximum external rotation (MER) of the shoulder complex during throwing in baseball players, and to analyze the correlation of each angle.The subjects were 19 collegiate baseball players. Throwing motion data was collected by three high-speed cameras and the three-dimensional (3D) coordinates of the shoulder complex were established by direct leaner translation method for the MER calculation. A 3D analysis was performed to obtain the external rotation (ER) angle of the glenohumeral joint, the posterior tilt angle of the scapula, and the extension angles of thoracic at MER of shoulder complex. The mean (±SD) value of the MER was 145.5±10.3°. The mean (±SD) values of the glenohumeral ER, the scapula posterior tilt angle and the thoracic extension angle at MER were 105.3±16.0°, 24.3±15.0°, and 9.1±7.2°respectively. Multiple linear regression analysis was used to relate the MER angle to each joint angle. The final linear regression model included the posterior tilting angle of scapula ( r=0.56, p<0.05), and external rotation of the glenohumeral joint ( r=0.40, p<0.05). Significant negative correlation was observed between the posterior tilting angle of the scapula and external rotation of the glenohumeral joint ( r=-0.52, p<0.05). This finding suggested that scapula motion could be very important for the prevention of throwing injuries.

The tongue in four species of penguin was investigated by light microscopy and by scanning electron microscopy, with special reference to the lingual papillae.1) The middle of the penguin tongue contains a pair of long cartilages and long tendons accompanied by striated muscle bundles.2) Large, spine-like, and caudally directed lingual papillae (filiform-like papillae) densely cover the dorsal surface of the tongue, apparently serving to catch fishes.3) By light microscopy, the dorsal lingual epithelium with the lingual papillae are seen as a thick cornified layer, but the lateral and lower surfaces have a thinner cornified layer.4) The connective tissue core (CTC) under the epithelium of the lingual papilla shows a stereo structure similar to but smaller than the external form of the papilla. The CTC contains some blood vessels and nerve fibers; the lingual glands are found in the submucous layer only in the posterior tongue.5) Bundles of nerve fibers in the lamina propria of the tongue were immunohistochemically positive for PGP 9.5, and it appeared that Merkel corpuscles were distributed in the connective tissue closely beneath the epithelium of the finger-like papillae, though they were only weakly immunoreactive for PGP 9.5.6) Numerous fine filaments of elastic fibers are found closely beneath the epithelial cell layer of the dorsal surface of the tongue including the lingual papillae, while there are very few of them on the lateral and lower sides of the tongue.

The present study was designed to investigate the kinematic factors related to sprint running velocity. The subjects were 71 sprinters(49 males and 22 females)who ranged from world class to collegiate level. Movements were recorded around the 60-m point from the start line during a 100-m race(during official races including world championships in athletics, or under experimental conditions)using 16-mm movie or video cameras. The official best time during recording of the movements was 9.86. The correlation coefficients between kinematic data(see Fig.1)and sprint running velocity were calculated for three groups(male, female, and all sprinters). Step length and step length index(step length/body height to exclude the effects of body height)were correlated positively and significantly with sprint running velocity for all groups(male, female, and all sprinter). Step frequency and step frequency index[step frequency・(body height/gravitational acceleration)^<1/2>to exclude the effects of body height]were correlated positively and significantly with sprint running velocity for all groups except male sprinters with regard to step frequency. With regard to leg swing, maximal thigh angle and maximal leg angle showed no significant correlation with sprint running velocity, but the minimal knee angle showed a singificant negative correlation with sprint running velocity for both male and all sprinters. These results suggest that the purpose of high knee drills generally carried out during training needs to be reconsidered. The maximal leg touch down velocity showed a significant positive correlation with sprint running velocity for both female and all sprinters. This probably means that the leg touch down velocity acts to reduce the deceleration at the moment of foot contact and to accelerate the subsequent leg swing back velocity during the foot contact phase. As for the support leg, the maximal leg swing velocity showed a significant positive correlation with sprint running velocity for all groups. Although the maximal hip extension velocity during the foot contact phase was correlated positively and significantly with sprint running velocity for male sprinters, the maximal knee and ankle extension velocity showed a significant negative correlation with sprint running velocity for female and all sprinters. These results suggest that the knee should not be extended to transfer the hip extension velocity effectively to the leg swing velocity during the foot contact period. This was borne out by the fact that the top sprinters entered in the present study hardly extended the knee of the driving leg during the foot contact phase.

阪神淡路大震災後の大規模な渋滞は,大都市の震災対応策に重要な教訓をもたらした.しかしながら,それから10年以上が経過しているにもかわらず,震災緊急時の交通対応の視点は基本的には変わっておらず,その教訓が十分に活かされる状況には至っていない.その原因の一つには,実際に現場でどのような現象が生じていたかが必ずしも明らかになっているとは言えないという点がある.そこで本研究では,最も重要な期間である震災発生後1~2日間における現象をあらためて明らかにするため,当時の状況に関する研究・文献等を調査し,被災地に流入できる全断面の震災直後の状況を把握する.また,これらの分析から,大都市における震災時の交通対応策に対して得られる教訓を整理し,現在の対策の課題を明らかにする.

This study was conducted to clarify the relationship between features of change in velocity and performance of world class athletes in the men's 400-m hurdle race(400mH).Nine final races of 400mH were videotaped with several video cameras panning from the start to the finish at 60 fields/s.After the time indication had been superimposed on each field of the VTR images, the time at touchdown immediately after hurdling was obtained.Using the flash of the starter's gun recorded on the VTR image, each hurdle touchdown time from the start, and each section thme(from each hurdle to the next)was obtained.The results of regression analysis showed a significantly high correlation (r=0.90, p<0.001)between 400mH performance and mean section velocity from the 5th to the 8th hurdle(H5-8), and a significant correlation(r=-0.61, p<0.05)between 400mH performance and te rate of deceleration in H5-8.These results indicate that in 400mH it is important to avoid decreasing velocity and to maintain a high velocity in H5-8 of the race in order to attain a high performance.

本研究の目的は、教育の脱集権化が現場の教育にどう影響し、教師たちの教育実践をどのように変容させてきたのかを明らかにすることである。本年度は、博士論文の執筆に向けて脱集権化改革初期の資料を収集し、集権体制から脱集権化に向けた動きが生じた背景を検討した。まず、2009年6月に行われた日本比較教育学会でラウンドテーブル「教育の『北欧モデル』の行方-学力問題に揺れる北欧諸国の教育政策」に参加し、スウェーデンの学力政策と分権体制に関するこれまでの研究のレビューを発表した。この中で、(1)脱集権化がグローバリゼーションとの関連で述べられる際、1990年代の現象として認識されているという誤り(2)日本においては、1960年代までの研究と1990年代以降の研究は盛んに行われてきたが、その間の研究がわずかにしか蓄積されていないこと(3)現在の教育改革を検討する上で、1970年代に起きた政権交代と政策の転換の理解が欠かせないことを指摘した。これを受けて研究の方向性を再吟味し、1970年代を始点(転換期)とした脱集権化改革の検討を始めることにした。2009年8月21日から10月2日にかけて、スウェーデンのウプサラ大学教育学研究所とルンド大学図書館を訪れ、資料収集と調査を行った。ウプサラ大学ではウルフ・P・ルンドグレン教授のもとで1970年代から80年代にかけての政策文書と教員組合の機関誌などの資料を200点以上収集し、歴史的な流れについて整理した。ルンド大学図書館では、1980年代のフリーコミューン(特区自治体)実験期に行われた学校開発活動の報告書を入手した。この調査から、脱集権化改革のアジェンダ設定が1970年国会における野党の提議によってなされたことと、その背景に社会構造の転換と教員組合のロビー活動があったことが明らかになった。さらに、注目すべきアクターとして、国会に設置された学校内活動調査委員会(SIA委員会)が浮かんできた。SIA委員会の資料は図書館に所蔵されているものについてはすべて収集した。1970年代のSIA委員会に関する研究成果は論文にまとめ、現在投稿に向けて準備中である。また、9月末にはアイスランドの就学前学級と小学校を訪れた。今回は最近できはじめている私立学校の動向について調査した。金融危機前後での教育政策の変容について現地の声を聞くことができ、非常に有意義であった。この成果は『比較教育学事典』に「アイスランドの教育」という項での執筆に反映されている。

The authors showed evidence of the usefulness of "Loggbok" for developing "self study planning ability" in Swedish compulsory schools. But, its educational effects have not been examined. Therefore, this study focused on the effects and the problems of the practical use of "Loggbok". The practical use of "Loggbok" was investigated by a questionnaire, class observation and interview. The questionnaire was distributed to three schools, asking the following questions: (1), do pupils have self-monitoring ability? (2), has the "ability to be responsible" been improved? and (3), does "Loggbok" help the incentive for learning? Class observation and interview in Eklanda-skolan focused on the following: (1), the teachers' approaches to prevent "drop out" and to foster a sense of responsibility in pupils, and (2), equality in teacher-pupil relationship.

An ion engine with 10,000sec-class high specific impulse is expected as primary propulsion for interplanetary space mission with extremely high delta-V, and needs high voltage for ion acceleration over 10kV. The microwave discharge ion source without solid electrodes can supply sophisticated technologies and simple composition on electrical isolation for such a high voltage. New electro-static grid made of carbon-carbon composite material was fabricated based on the numerical simulation of “igx” code. The “μ10HIsp” ion engine combining the ECR ion source, microwave discharge neutralizer, DC blocks, propellant isolators, carbon-carbon composite grid and so on generated successfully a plasma beam with 10,000sec specific impulse using 15kV acceleration voltage.

The magnitude of mechanical stress at the shoulder and elbow appears to be directly correlated with the degree of maximum shoulder external rotation (MER) during throwing. Therefore, it is very important to prevent excessive MER to minimize the risk of throwing injuries. The purpose of this study was to investigate the relationships between MER during throwing and the kinematic parameters of throwing mechanics, shoulder muscle strength, and shoulder range of motion in high school baseball players. The subjects were 40 male high school baseball players with no elbow or shoulder joint problems. Three-dimensional analysis was performed to calculate the MER angle. Then, the shoulder and elbow angles at initial foot contact (IFC) were computed. ROM and muscle strength of shoulder joint were also measured in each subject. Multiple linear regression analysis was used to relate the MER angle to these factors. Significant correlations were observed between the MER angle and the external rotation (ER) angle (r=−0.51, p<0.001) at IFC, and the ER range of motion (r=0.84, p<0.01). The MER angle significantly correlated with shoulder internal rotation (IR) at IFC. This finding suggests that stress on the shoulder and elbow could be increased by the degree of shoulder IR angle at the moment of IFC. Further, excessive ER range of motion may also be a risk factor.

This paper presents a new concept of a flexible mobile and versatile shape reconfigurable control mechanism of a robot, called a versatile robotnoid (Vroid), which can be applied for plant maintenance works and other outdoor operational works, where its working environments are restricted due to mobil space and terrain. The Vroid I based on the multiple link-wheel mechanism has abilities of passing through rough terrains, passing over obstacles and going up and down stairways. Compared the Vroid I with conventional wheel, crawler and legged locomotion types of the mobile mechanisms, the proposed one is considered to be superior to those from the viewpoint of flexibility and adaptability to working environments. Utilizing the redundancy of joints in degrees of freedom, a method of the joint static control sequence is proposed to minimize the torques required to joint rotation under some constraints, which can easily be solved by the linear programming approach.

In competitive sports, complex movements by athletes can be observed.These movements are highly rationalized and sophisticated, compared to movements in the activity of daily life. They are practised and perfected in order to win. This all too often leads to injury. Stability is defined in various ways, but in this paper, stability and stable movements are defined as movements with the minimum of sports injuries but the maximum of sports performance. Movements that are likely to cause injuries and have a bad effect on performance are defined as unstable movements. The movements seen in running, throwing and tackling are focussed on mechanical factors related to injuries. Points of importance are made with regard to stability.
