For the purpose of determining the technical characteristics of the Kendo strike with the Jodan-no-Kamae in Kendo, we measured the impact force of the one-hand Shomen-and Kote-uchi using as subjects five college Kendo club students. And analyzed the data by a motion analysis system with a video tape recorder. We also measured the impact force of the two-hand Chudan-no-Kamae strike for comparison. The following are the results obtained from a biomechanical examination of the data.1. The downward maximum magnitude of the impact force of the one-hand Kote-Uchi (150.03 ± 21.35kgf) was greater than that of the one-hand Shomen-Uchi (120.99 ± 11.55kgf). This difference was a characteristic of the one-hand strike but not of the two-hand strike.2. The angular motion at the left shoulder, from which the Shinai is brought down, was greater for the one-hand Kote-Uchi than for the one-hand Men-Uchi. This will explain why the vertical component force of the one-hand Kote-Uchi was greater than that of the one-hand Men-Uchi.3. With respect to the vertical movement of the Kensen, the maximum speed was greater for the one-hand Kote-Uchi than for the one-hand Men-Uchi while the opposite was the case with respect to the forward movement. This was in accord with the observation that the maximum magnitude of the impact force was greater for the one-hand Kote-Uchi than for the one-hand Men-Uchi with respect to the vertical movement whereas the opposite was the case with respect to the forward movement.4. The correlation coefficient between the impact time and the maximum magnitude of the impact force was small whereas the correlation coefficient between the impact time and the impulse value was great.5. There was not an appreciable difference in the magnitude of the impact force between the one-hand and two-hand Men-Uchi. However, with respect to the right Kote-Uchi, the maximum magnitude of the impact force was greater in every direction for the one-hand strike than for the two-hand strike. Most notably, with respect to the downward movement, the maximum magnitude of the impact force of the one-hand Kote-Uchi was greater than that of the two-hand Men-Uchi.

For the purpose of determining the technical characteristics of the striking motion from Nito-no-Kamae in Kendo, we measured the impact force of the striking motion with DAITO (long-shinai) and SHOTO (short-shinai) using as subjects three male university teachers, who are majoring in Kendo, and analyzed the data by a motion analysis system with a video tape recorder.For comparison, similar measurements were performed on the striking motion with the two-handed striking motion from Chudan-no-Kamae and the one-handed striking motion from Jodan-no-Kamae.The following results were obtained from a examination of the data.1. The maximum downward magnitude of the impact force and the downward impulse value of three kinds of the striking motions with SHOTO from Nito-no-Kamae were greater than that of the two-handed Shomen striking motion from Chudan-no-Kamae. However, the maximum downward magnitude of the impact force and the downward impulse value of two-kinds of striking motion with DAITO from Nito-no-Kamae were smaller than that of two-handed Shomen striking motion from Chudan-no-Kamae.2. The impact time of all the striking motion from Nito-no-Kamae were shorter than that of the two-handed striking motion from Chudan-no-Kamae.3. The motion of shinai in the striking motions from Nito-no-Kamae were chiefly made using the left elbow and the left wrist.4. The angular velocity of shinai immediately before impact using Hikikote striking motion with SHOTO of Nito-no-Kamae was the largest, and that using the Shomen striking motion with DAITO of Nito-no-Kamae was the smallest.

「教育技術の法則化運動」では,教師の力量を高めることを目的としており,共鳴する教師も多い。体育科教育学においても,教育技術の確立は重要な課題である。学部教育において,小学校教員養成課程学生対象の授業を行っている筆者としても,体育授業について学生たちの指導力養成を果たさねばならないが,体育実技については苦手・嫌いの学生も多く存在しており,指導力養成には非常な努力を強いられている。水泳の授業では,できないと思われている「バタフライ」を取り上げ,誰もが泳げるようになることを目指して指導している。この実践を踏まえて,誰もが教えることのできるバタフライの指導方法の確立を目的として,指導の順序と指導者の発言内容を示した。特に「バ夕足」ではなく,「旗(はた)足」という新造語を使って,無駄な力を使わない泳ぎの習得を目指しての指導方法を提言した。この指導方法を使っても,直ちに誰もがどの子どもをも泳がせるのは難しい。学習者一人ひとりに対応できるかどうかという教師の指導力によって左右されるのである。体育についても,「教育技術の法則化運動」は未だ,一人ひとりの子どもに対応できるような教育技術を数多く確立しているとは言えない。現在までの「教育技術の法則化運動」には,「つまずきの原因を見抜く力量の必要性の検討が不足」・「すぐに役立つという表現が曖昧」・「定石についての考え方に異論あり」などの問題点があることを述べた。今後これらの問題について検討を深めることは教員養成の仕事にも関わり,筆者の今後の課題でもある。

A 2/3inch 2M pixel CCD HDTV camera has been developed in response to the demand for small size, light weight and high picture quality. This camera uses newly developed 2/3 inch 2M pixel MFIT CCD and with the development of a high speed CCD signal processing technology realize the performance which is over 1 inch 2M pixel camera. And also we realize a horizontal resolution of 1200TV lines and an amplitude response of more than 40% with a development of single channel CCD transfer method and high precision offset imaging technology.
