現在のDVD-RAMは片面2.6GBであり,近い将来でもせいぜい4.7GB/片面一層のメモリ容量しか期待できない。現在強く求められている少なくとも2時間の動画像を記録再生できる15GBのメモリ容量で,かつ現在の10Mbps前後のデータ転送速度を大幅に高速化した100Mbpsを上回るデータ転送レートが可能な光ディスクシステムのキー部品である光ヘッドの新方式について述べる。本研究は高精細な動画像伝送や将来の家庭用の光通信網が整備された場合の伝送速度である100Mbpsから400Mbpsのビットレートで情報を記録再生できるVCSEL(垂直共振器半導体レーザー)アレイを記録ヘッドとしている。高密度化のためにはソニーが既に発表している二レンズ方式による対物レンズを採用し,かつ3×3のVCSELアレイを用いることにより従来に比べて9倍速のデータ転送レートの向上が期待できる。従来の点光源に対して本研究では面光源である為コリメーターレンズに像面湾曲収差を補正した両面非球面レンズを用い,対物レンズとしては球面収差を補正した高NAの非球面レンズの採用を提案している。

スケトウダラとパシフィック・ホワィティングの混合肉糊に3% 牛血漿粉末を添加し, 30℃ または50℃ で数時間予備加熱し, さらに90℃ で20 分加熱した. 30℃ で加熱すると, 続く90℃ の加熱によって肉糊は強い坐りゲルを形成するようになり, 二段加熱ゲルの破断強度とゲル剛性は高値に達する. 混合肉中のスケトウダラの割合を増やすと, 破断強度の最大値は比例的に増加するが, ゲル剛性はあまり増加しなかった. 一方, 50℃ で加熱すると肉糊は坐りゲルを形成せず, 全ての二段加熱ゲルの物性は低値に留まった.これらの結果は, 二段加熱ゲルの物性を大きく増強させる牛血漿粉末の機能が, 坐りを伴うゲルと坐りを伴わないゲルに対してでは明らかに異なることを示している.The functional effect of bovine plasma on heat-induced gel formation of the mixture of salt-ground meats from walleye pollack and Pacific whiting surimi was investigated in connection with preheating temperature.The mixture of salt-ground meats was preheated at 30 or 50℃ for several hours in the presence of 3% bovine plasma powder, and subsequently heated at 90℃ for 20 minutes to prepare two-step heated gel.Preheating of the mixture of salt-ground meats with bovine plasma at 30℃ increased the breaking strength and the gel stiffness of two-step heated gel. The maximum values of breaking strength were proportionally increased with rising of the ratio of walleye pollack surimi in the mixture, but those of gel stiffness were not increased. On the other hand, the preheating of the mixture with bovine plasma at 50℃ did not promote gel formation and consequently the breaking strength as well as the gel stiffness of all of two-step heating gels remained lower values.These results indicated that a functional effect of bovine plasma powder on the heat-induced gel formation of salt-ground meats with and without setting was evidently different.

赤外線サーモグラフィは体表温度分布の受動的検査法で,その医学的意義,安全性から見て極めて理想的な臨床検査法である。医用サーモグラフィでもっとも重要なことは,身体各部の温度分布を正確に比較することである。しかし,従来の面走査方式のサーモカメラではカメラに面した身体の1側面を平面視した熱画像しか撮影されないため,種々の問題があった。とくに臨床応用においては異なる対象面毎に複数の撮影を余儀なくされていた。そこで著者らは身体各面の熱画像を1回の操作で撮影することのできる新たな展開サーモグラフィ法を3種考案した。(1)3面サーモグラフィ(TAT):側面用の赤外反射鏡を用いて身体3側面の熱画像を同時に撮影する方法。(2)多面サーモグラフィ(MAT):身体を回転しながら高速サーモカメラで体表のリアルタイムサーモグラムを撮影,記録し,1回転後任意の対象面の熱画像をマルチ表示するほか,身体全周域の熱分布を回転面の実時間サーモグラム上で観察することのできる方法。(3)パノラミックサーモグラフィ(PT):身体を中心軸の回りに回転しながら,回転軸上の体表面をサーモカメラで線走査して,体表全域までの連続的な熱画像を撮影する方法。展開サーモグラフィ法は次のような利点がある。(1)身体各面の温度分布を同時に記録,観察,分析することができる。(2)身体全域の温度分布を連続的に記録,観察することができ,異常部の検出エラーがない(PT,MAT)。(3)PT法では面走査法に見られる測定対象の周辺部における温度低下の現象を伴なわず,すべての範囲で正確な測定値が得られるため,誤診の危険性がない。(4)PT法では像拡大に伴なって分解能が向上し,精査に利用できる。(5)本法は操作が簡単で,規格的検査ができる。以上のように,本法は従来のサーモグラフィ法の欠点を改善した画期的な技術で,診断学上(とくに癌の診断などに)大きな成果が期待される。

1. Purpose We intended to grasp the mental conditions of Hakone-Ekiden Athletes in Tokai University teams. Recently, in sports world it is important to maintain mental condition rather than physical condition. In this paper, we made a comparative study of the investigations in 1988 and 1990. 2. Procedure 1)Tests (1) Uchida-Kraepelin Psychodiagnostic Test (U-K Test) (2) Yatabe-Guilford Personality Inventory (Y-G Test) 2) Subjects Tokai University teams of Middle and Long-distance blocks. (1) Regular groups; 13 athletes (2) Semi-regular groups; 7 athletes 3) Testing term and place December, 30,1990,9 : 00AM. At Tokai University, Shonan Campus. 3. Results 1) U-K Test The result of the analysis showed that the characteristics of the personalities of athletes are full of variety. No.5 Type -8 athletes, No.10 Type-4 athetes, No.4 Type-3 athletes, No.6 Type-2 athletes, 3-1d Type-2 athletes and No.2 Type-1 athlete. 2) Y-G Test The result of the analysis showed that D Type-9 athletes, A Type-4 anthletes, E Type-4 athlletes, C Type-2 athletes and B Type-1 athlete. 3) Mental health The result of the analysis showed that the mental health of the athletes in the regular group and in the Sem-regular group are in the similar degree. 4. Conclusion By two investigations in 1988 and 1990,we guess that we had better select representative athletes with a high degree of mental health and a high fucuturation rate in the latter period.

1. Purpose We intended to grasp the mental conditions of Hakone-Ekiden Athletes on Tokai University teams. Up to this time, the regulation of physical conditions of athlete has been comparatively, easy to put into practice. But we are not able to establish a definitive method to regulate the mental condition at the present. By the investigation mentioned below, we wanted to contribute to explain the mental condition of athletes and applied the results of this investigation to the selection of representative athletes for Hakone-Ekoden. 2. Procedure 1) Tests (1) Uchida-Kraepelin Psychodiagnostic Test. (2) Yatabe-Guilford Personality Inventory. 2) Subjects Tokai University teams of Middle and Long-distance blocks. (1) Regular groups : 14 athletes (2) Semi-regular groups : 14 athletes 3) Testing term and place December, 31,1987 At Tokai University, Shonan campus in Matsumae-kaikan. 3. Result 1) Mental health The result of the analysis showed that the mental health of the regular group is higher than that of the Semi-regular group. 2) U-K Test The results of the analysis showed that the characteristics of the personalities of athletes are full of variety. No.5 Type-7 athletes and 3-1 Type-4 athletes is a notable result. 3) Y-G Test The result of the analysis showed it remakable that D Type is to be 15 athletes in 28 athletes. 4. Conclusion 1) We selected a representative athlete with a high degree of mental health and a low fluctuation rate of the latter period. 2) The selection of the representative athlete for No.4 block failed 3) It can be pointed out that the most remarkable feature of an athlete found to be in bad condition is that the work efficiency dropped for 12-15 minutes of the latter period of the Test.

Recientemente, el autor ha hecho una investigation sobre la personalidad de los Nikkeis brasilefios enfocada especialmente a los universitarios (19 varones y 24 mujeres) utilizando la prueba psicologica del MMPI (Inventario Multifacetico de Personalidad de Minnesota). For otra parte, el habia aplicado la misma prueba a los universitarios japoneses hace varios afios obteniendo la media y desviacion estandar de ellos. Se ha esclarecido a traves de la comparacion las caracteristicas de la personalidad de los Nikkeis brasilefios. En el caso de los varones Nikkeis, la escala K es notablemente mas baja que los japoneses, lo que siginifica que los Nikkeis contestaron a la prueba en forma menos defensiva que los japoneses. Cuando la aplicamos a una poblacion general que no tenga el motivo de consulta, siempre la escala K se situa en un nivel alto. Precisamente los universitarios japoneses respondieron de esa manera. Los Nikkeis, en entrevistas, comentan frecuentemente sobre su identidad nacional a veces presentando cierta ansiedad relacionada con su nacionalidad. For consiguiente, ellos tienen el deseo de conocerse a si mismos y su personalidad. Tambien los Nikkeis mostraron un alto nivel de aspiraciones y deseo. Cuando vemos el bajo nivel de la escala 2(D) y el alto nivel de la escala 9 (Ma), dicha tendencia es muy clara. En el caso de las mujeres, la caracteristica de los varones Nikkeis es mucho mas acentuada al compararlas sobre todo con las japonesas. A traves de la investigation, se ha aclarado que los Nikkeis brasilefios tienen alto nivel de aspiraciones, y al mismo tiempo, que muestran cierta preocupacion relacionada con su identidad nacional.

Working in collaboration with the United Nations Environment Programme (UNEP), NPO Global Sports Alliance (GSA) is the world's first international NPO working to promote environmental awareness and action through sport. Among GSA and UNEP's collaboration projects is the Nature and Sports Camps (Dream Camps), which aim to give sporting equipment and professional training to children in developing countries that would not ordinarily be given such a sporting chance'. Started in 2001, numerous events in tennis, football, volleyball, basketball, swimming and so on are held throughout the year in and around Nairobi, Kenya, which is also where UNEP head office is located. As well as professional coaching provided by international volunteer coaches and Kenyan sports associations, education on environmental and social issues, such as water, public hygiene, pollution, health and HIV/AIDS, is provided by UNEP. Participants in the program receive sports training, discover new skills, learn about the environment and take part in local clean ups in the hope of promoting not just sporting excellence but nurturing new community leaders. Providing sports training and education, the Nature and Sports Camps carry a reputation as the biggest and most successful camps of their kind in East and Central Africa. As a member of GSA's staff, I flew to Nairobi and participated in the Camps in August 2005 as a volunteer tennis coach. I would like to report on the month I spent in Kenya, staying at the Sadili Oval Sports Club, where some of the camps took place.

The analysis of evaluation of instruction by students can be the most powerful tool available to instructors for the improvement in their own instruction technique. A questionnaire named minute paper soliciting students' evaluation of instruction was given out to the students of 3 courses at Tokai University during 1989 every time. The minute peper has five questions: what are points of important and doubt of this instraction?, how is evaluation by yourself as student in this class?, how is evaluation of this instruction?, What are good items of this instruction?, What are bad items? In this paper, how to use the minute paper, useful point of the minute paper, relationship between evaluation value of the minute paper and total evaluation value of a semester are introduced. The minute paper had 8 useful points : it is possible to make improvement of instruction every time, to see students' understanding and others. The total evaluation value of a semester was higher than it of the minute paper.

A certain On-Gana found in the ancient Japanese documents may be derived from Korean Language. In order to prove the hypothesis, I have tried to examine some Chinese characters and, as a result, I am assured that Chinese Characters, '叱' '伐' and '支' used as OnGana (seen in Nihonshoki), are derived from Korean Language. In this paper, I intend to examine the Chinese Characters, '旱' and '干' through the ancient Japanese documents, and explain the usage of them as On-Gana.

The purpose of this study was to investigate the effect of. "TANDEN"-breathing (which is one of an adminal breathing method is used,by KOBUJYUTSU training) on blood lactate after high intensity running exercise. Thirty healthy basketball players of high school student participated in this study. They were separated to control group and "TANDEN" group and the "TANDEN" group trained TANDEN-breathings for 30 days. The exercise test underwent 3 times, (before beginning training, 15 days and 30 days after training.) Their blood lactate were measured on 0, 10, 20 and 30 minutes after the high intensity running exercise. There were no differences among training periods in control group. In TANDEN group, there were significant differences among training period, (p < 0.05) In comparision with control group,the decreasing rate of blood lactate were significantly grater in TANDEN group, (p < 0.05) These results suggest that to control breathing after high intensity exercise is effective to remove blood lactate which made by high intensity exercise in a short time.

As a result of rapid progress in computer graphics and CAD techniques. the clinical use of 3-dimensional images as an aid for various medcal procedures is becoming increasingly common. One such application is the surgical simulation system, which assists surgeons in planning surgical procedures by allowing them to be performed first on the computer screen. Great progress in medical electronics and computer technologies has made useful surgical simulation syttems possible. However there are some problems which prevent routine use of the system. This paper describes research towards soluins these problems, which involves understanding the technical status of recent surgical simulation systems.
