両側前頭葉損傷後,強制的に人物とりわけ人の眼を中心に凝視ないしは注視 (forced gazing) を続ける2 症例を報告した。この2 例では,人が視界に入れば必ず凝視ないしは注視が誘発され,人が視界から消えるまで持続した。すなわち,この行動は,外部環境刺激に対して戸惑うことなく駆動され継続した。  forced gazing は,能動性がほとんどみられない患者に出現する,外部の環境刺激に対して視線が自動的に反応する被影響性が亢進した現象と考えられ,また前頭葉の損傷による抑制障害のため頭頂葉の機能が解放された結果,これらの行為/行動が出現したと考えた。本2 症例は前頭眼野を含む広範な両側前頭葉損傷であった。本2 症例に随伴した把握現象や道具の強迫的使用から両側前頭葉内側面損傷がforced gazing の責任病巣の中で最も重要と考えられ,前頭眼野も責任病巣の1 つと考えられた。

The friction coefficient μ on the contact point position between a wheel flange and a rail is said to seriously affect on the occurrence of the wheel-climb derailment. However, the method to quantitatively and exactly evaluate the μ has not suggested until to the present. The authors proposed a method to easily and exactly evaluate the value, and made it clear by an experiment, employing a 1/5 scale model track and model truck. The result obtained through the experiment indicates that the value on dry rails has a similarity with that of the adhesion coefficient, and that the dry rail on the main line keeps the value at high level. Using the μ value obtained by the studies, the risk of the wheel-climb derailment was evaluated. As the result of the evaluation, they found that higher μ value than the conventionally used one should be introduced for the risk evaluation of the derailment, and that very short term lateral force below 60 ms should be observed on the steep curvatures.

The entry rate into the elite of university graduates who graduated with honor was higher than that of other graduates in Japan in the pre World War II period. What kinds of effects can explain this phenomenon? Three possibilities can be considered to explain it: first, honor graduates may be more successful in any job, so that there would naturally be a correlation between the university adaptability indicated by high grades and vocational success; second, they might have found it easy to gain sponsorship from established elite groups because of their honor grades, even if there were no necessary correlation between college grades and vocational success through severe competition; third, they may have found it easier to enter vocational sectors which were more accessible to the elite. The aim of this paper is to clarify how these three possibilities worked to create elites in the pre-war period, sampling mainly Summa Cum Laude graduates from Tokyo Imperial University. The main findings are as follows: (1) it is clear that Summa Cum Laude graduates entered jobs which were more accessible to the elite, such as Imperial University professorships or prestigious government positions; (2) they were more successful in whatever job they entered; (3) however, it is obvious that the Summa Cum Laude graduates received some special treatment in becoming Imperial University professors and were sometimes given advantageous positions and experiences as government officers, despite the fact that the competition for high elite positions in private companies was based on merit.

Now defunct Japanese Navy prescribed, at its designing of war crafts, in consideration of their stability capacity, the permissible lowest values of GM, OG, Stability range, etc. separately, in accordance with the class of vessels and their sizes.Later on, however, due to the development of stability theory, it became possible to determine the stability capacity, by applying the organic relation of these values mentioned above and obtaining a value that is the combination of these values.In this thesis the authors, basing upon the“Theory of Safety Criterion of a Ship”established by Prof. Watanabe, have calculated the Safety Criterion c Value, studying the actual instances of 15 vessels, including destroyers and torpedo boats of the defunct Japanese Navy, and about 90 of their different conditions and analysed them from various angle, such as the transition of the history, and the statistic distributional state.This study of the authors has led to the possibility to determine the permissible lowest value of safety criterion of naval small crafts.

We compared the invasion of Gamma nails (GN) and Compression hip screws (CHS) in operations to determine blood loss.25 trochanteric fractures treated with GN, and 24 with CHS were available for prospective study. We exchange the amount of transfuse blood for the rate of change of hemoglobin content (Hb), and investigated the difference of it. Hb for GN was more reduced compared to Hb for CHS from time of operation to the next morning. But external blood loss for GN was less compared to CHS.We concluded that internal blood loss for GN was much higer than CHS, so the invasion of GN is not low in the point of blood loss.

宇宙初期の物理などの観点から超相対論的な極限状態のプラズマの非平衡現象は非常に興味深い。本論文では古典力学から非可換ゲージ理論にわたるさまざまな系において輸送方程式(Boltzmann方程式)を議論する。前半は力学系の締約理論としてのくりこみ群法を用いて古典力学と場の理論においてBoltzmann方程式を導出する。後半は非可換ゲージ理論での輸送方程式とそこに現れる赤外発散の問題について議論し、電弱理論におけるバリオン数の破れの問題への応用をレビューする。

The wind velocity of the overturning of a vehicle due to cross-winds depends on the aerodynamic characteristics of the vehicle on the ground, an embankment or a bridge. The field tests were made on the aerodynamic characteristics of the vehicle at rest on the bridge and the wind tunnel tests corresponding to the field tests were also made. The results of the wind tunnel tests agreed with those of the field tests qualitatively.
