映画「風の谷のナウシカ」に登場する架空の乗り物であるメーヴェの飛行可能性を検討するために,実機を忠実に再現する模型を製作し,風洞試験によりメーヴェの空気力学的特性を明らかにした.また,風洞試験結果に基づいて,飛行に必要な基本的な性能および安定性の評価をおこなった.その結果,メーヴェは飛行を実現するのに十分な性能を有するが,現在の機体形状のままでは縦揺れの安定性を確保することができず,飛行の実現は困難であることがわかった.Mowe is a fictional flying vehicle appeared in the animated cartoon "Nausicaa of the Valley of Wind". The airframe configuration of Mowe is very unique without vertical and horizontal tail, and its main wing is only equipped with flaperon as a pitch and roll control surface. However, to realize a tail-less plane such as the Mowe, detailed consideration about the aerodynamic configuration is needed from a viewpoint of aeronautical engineering. In this paper, in order to obtain aeronautical characteristics, aerodynamic forces and moments acting on the scale model with deflectable flaperon were measured experimentally by using wind tunnel at Chiba University. And we also estimated aerodynamic performance and stability based on a result from wind tunnel testing and considered realization of the flight.

化学物質の新たな存在形態となりうる、マイクロカプセルを介した化学物質の環境中動態、野生生物の蓄積および生態影響について明らかにする。マイクロカプセルとは、芯材に様々な化学物質を封入した微細な粒子状物質を指す。カプセルに封入された化学物質は、化学物質本来の化学構造から推定される環境動態とは異なる動きを示す。よってその動態解明は新たな研究分野として重要である。本研究ではマイクロカプセルの水環境中での拡散・環境動態および水生生物に与える影響を明らかにし、さらに揮発性・難水溶性の化学物質を内包したマイクロカプセルを合成し、カプセル化した場合としない場合とでの生物影響の差を調べる。

There are many studies on a variety of social behavior mediated by oxytocin. Of the studies, several suggest that oxytocin is deeply involved in empathy. Empathy toward other individuals is thought to be necessary to give rise to helping behavior. However, there has been little research on the relationship between oxytocin and helping behavior. We investigated helping behavior in oxytocin receptor knockout prairie voles. Prairie voles are known as socially monogamous rodents with high sociality. To examine helping behavior, we used a paradigm in which voles helped a conspecific soaked in water by opening a door. The prairie voles were housed in pairs. All the pairs were siblings. One of the pairs was assigned to be a soaker vole and the other was assigned to be a helper vole. There were two groups; the oxytocin receptor knockout and wildtype groups. The oxytocin receptor knockout voles were paired with wildtype siblings and were assigned to be the helper. Their wildtype cagemates were assigned to be the soaker. The experimental apparatus was divided into two areas; a pool area and a ground area. These areas were separated by a transparent acrylic plate on which a circular door was attached. The soaker vole was placed in the pool area and the helper vole was placed in the ground area. The door could be opened only from the ground area. We measured door-opening latencies. After the door-opening, the pair of the voles were allowed to interact. At that time, the huddling time was measured. As a result, the oxytocin receptor knockout voles showed significantly longer latencies for opening the door than the wildtype voles. In addition, the oxytocin receptor knockout voles showed shorter huddling time than the wildtype voles. These suggest that oxytocin is important for empathic behavior.

本研究ではトレーニング方法の相違による体幹伸展筋群の筋活動を比較し,体幹伸展筋群のトレーニング方法における筋活動量の段階付けを行うことを目的とした。被験者には①腹臥位で最大筋力発揮,②腹臥位で対角上下肢挙上,③徒手筋力検査(MMT)5,④四つ這いで対角上下肢挙上,⑤MMT3,⑥逆ブリッジ,⑦ブリッジ,⑧座位で重錘挙上,⑨座位で上肢挙上・頭部伸展を行わせ,その肢位を3秒間保持させた。その際,胸部傍脊柱筋(T9),腰部傍脊柱筋(L3)から表面筋電図(EMG)を導出し,積分筋電図(IEMG)を求めた。その後①のIEMGを基準とし②~⑨の最大随意収縮に対する割合(%MVC)を求め,T9・L3における②~⑨の筋活動量を比較,分類した。その結果,T9ではA②・③・④,B⑤・⑥,C⑦・⑧・⑨に,L3ではD②・③・⑤・⑥・⑦,E④,F⑧・⑨に分類することができた。T9ではA,Bは最大筋力の増強,Cは筋持久力増強に適していることが推測された。L3ではDは最大筋力の増強,Eは筋持久力増強,Fは筋力増強効果が期待できないことが推測された。

After the severe accident in the Fukushima-1 nuclear power plant, a large amount of contaminated stagnant water has been produced in turbine buildings and surrounding areas. This rapid communication reports the calculation of the radionuclide inventory in the core, the collection of the measured inventory in the stagnant water, and the estimation of the radionuclide release ratios from the core to the stagnant water. The present evaluation is based on data obtained before June 3, 2011. It was revealed that the release ratios of tritium, iodine and cesium were several tens of percent, while those of strontium and barium were smaller by one or two orders of magnitude. These release ratios of the Fukushima accident were equivalent to those of the TMI-2 accident.

We tested the reputation maintenance hypothesis of ingroup favoritism. Ninety-two non-student participants played one-shot prisoner’s dilemma games with an ingroup and an outgroup partner with minimal groups, and showed ingroup favoritism only when the participant and his/her partner knew each other’s group membership (common knowledge condition). The ingroup favoritism observed in the common knowledge condition positively correlated with fear of negative evaluation. These results provide support for the reputation maintenance hypothesis.

Empirical studies have shown that beliefs in conspiracy theories are associated with low self-reported attitudinal trust in other people in general. However, self-reports do not always reflect actual behaviors. The present study investigates whether beliefs in conspiracy theories are negatively associated with actual trust behavior. We conducted a secondary analysis to examine correlations between conspiracy beliefs and trust behavior measured in a monetarily incentivized economic game (trust game) as well as self-reported attitudinal general trust. The results demonstrated that the more people believed in conspiracy theories, the less they entrusted their money to strangers when there was a risk of being betrayed and losing money. The present research confirms that conspiracy beliefs are associated with low trust regardless of whether trust is self-reported attitude or actual behavior which entails the risk of betrayal.

This study investigated the cognitive basis of self-effacing behavior among the Japanese. Based on the premises that self-effacement among the Japanese is a form of "default self-presentation," we predicted that Japanese self-effacement will dissipate when actual self-evaluation is required. The experiment (n = 110) consisted of two phases. In Phase 1, participants took a "cognitive ability test" that consisted of 20 questions. In Phase 2, they were asked to judge if their performance on the test was above or below the average performance level in their school. In the bonus condition, participants were rewarded for making a correct judgment in their performance. In the fixed-reward condition, no reward was provided for making a correct judgment. The results from experiments 1 and 2, taken together, indicate that self-effacement observed in the fixed-reward condition was not confirmed in the bonus condition. These results suggest that self-effacement among the Japanese is a strategy for self-presentation, which they switch on and off depending on the situation.

This paper treats how carpenters in the Middle Ages inherited and accumulated their techniques. First, an investigation revealed carpenters who come from advanced countries to bring new various techniques. Another investigation then the foreign technology was inherited by local carpenters, and they were able to build by themselves. Finally, still another investigation of an unknown craftsmen acquired high skills and productivity, and social standing improved. Consequently, the transition of carpentering could be understood by organizing it into three periods.

YAMAGISHI, Satoshi (Tenryu Low. Sec. School, Nagano Pref.) Roosting behaviour in crows. 1. Autumnal and wintry roosting behaviour in Nagano Prefecture. Jap. J. Ecol. 12,54〜59 (1962) The roosting behaviour of crows was observed in Nagano Prefecture, and the results are as follows : (1) In the daytime in autumn crows form small flocks in their habitat and feed there. Before sunset they gather at their regular assembling places, and then move to roost in groups. The group at the farthest assembling place from the roost move first, joining the nearest group, one by one, and at last all of the crows reach the roost. (Fig. 1) (2) There are three roosts in autumn in Upper Ina-gun and Lower Ina-gun ; in winter one of these three is used as their wintry roost, and the other two are canelled, being used only as their assembling places. Crows' number in each of these three autumnal roosts is about 900,and the number in one wintry roost is about 3,000. (Fig. 2) (3) The numbers of the above-mentioned wintry roosts are seven in Nagano Prefecture ; crows' number in each of them is 1,000〜3,000. Only ever-green woods are used as the wintry roosts, the main tree species of which is Japanese red-pine. (Fig. 3,Table 1) (4) In the future I intend to investigate on crows' roost in their breeding season and the actual organization of their society.
