This article is an attempt to clarify the transformation that took place in military operations under the Muromachi shogunate after the violent protests for the remission of the debts that took place around Kyoto in 1441 (Kakitsu-no-Ran), from the time when the shogun's administrative advisors (kanrei) took control of the shogunate until Shogun Ashikaga Yoshimasa assumed leadership. Day to day military affairs during the "kanrei regime" were administered by Bakufu functionaries (bugyonin) and members of the kanrei's personal entourage (uchishu). However, in the midst of the political instability that followed the uprising, it became difficult to gain a consensus among the feudal lords (daimyo) and thus organize an allied army made up of troops led by provincial military governors (shugo). There-fore, regional conflicts that arose during this time would be pacified by local samurai (kokujin) from the nearby provinces coming to the support of the military governor of the province in question. In 1455, when Yoshimasa established firm control of the shogunate, the military system was reorganized mainly by Kanrei Hosokawa Katsumoto and the shogun's close advisor Ise Sadachika, meaning that in addition to the conventional "kanrei route" of reporting incidents to the shogun, a new route was established through Sadachika. However, between 1456 and 1461, the former route gave way to the latter, to the extent that the kanrei's position in military affairs became unclear, while Sadachika became Yoshimasa's advisor in military decision making and information reporting. During that time, troops under allied command of military governors were often deployed to quell regional conflicts, a widespread practice which caused mutiny among troops discontented over conscription, as local-based samurai were being conscripted repeatedly, to a degree of exhaustion. The period from the beginning of Yoshimasa's regime until 1460 was also a time marked by dysfunctionality in the Bakufu's system of military mobilization. It was for the purpose of correcting this problem that coercion was used to muster local-based samurai into service for the shogunate. Yoshimasa's efforts to pacify unruly provincial feudal lords, take back and directly manage proprietorships of religious institutions and mobilize local-based samurai met with failure, and he wound up faced with the rebellion of 1467 (Onin-no-Ran) without a solid military organization made up of those political forces. Yoshimasa's over-reliance on Sadachika had sorely weakened the military role of the kanrei in the Bakufu and caused its eventual hollowing out by the outbreak of the rebellion. The Hosokawa family was forced to conduct its functions as kanrei in isolation from the Bakufu's central bureaucracy. And although Yoshimasa was able to regain his control of the Bakufu through such extreme polarization and the efforts of Ise Sadamune, the Muromachi shogunate would never again play the leading role in conducting military operations.

Many objective characteristics of loudspeakers are measured in factories and laboratories, but there is little knowledge about how they affect sound quality. It is necessary to reveal the relation between objective characteristics and sound quality in order to improve sound quality of loudspeakers. In this paper, the relation between subjective evaluation of sound quality and objective data to reveal the characteristics which influence sound quality to a great extent is investigated. In the subjective listening tests, preference judgments which were subjected to factor analysis, similarity judgments which were subjected to multidimensional scaling and verbal descriptions of sound quality were carried out. The factor analysis of preference data yielded a preference space of three factors (Fig. 5). The first of them is the "consensus preference" factor and the remaining two are the "individual difference" factors. As a result of multidimensional scaling, similarity data are summed up in three psychological dimensions (Fig. 7). Interpretation of these dimensions indicates that they represent "volume and extent", "brightness" and "beauty" respectively (Fig. 7). The relation between objective data and subjective data was analyzed in two respects. Firstly, measured data sixteen objective characteristics were rated from the view point of high fidelity reproduction (Table 3). These characteristics were fitted into the preference space as vectors (Fig. 14). Rating scores of sound pressure responses measured in a listening room and an anechoic room have a high correlation with the "consensus preference" factor. Secondly, similarity of response patterns among loudspeakers was calculated for each objective characteristic and it was subjected to multidimensional scaling. The configurations of loudspeakers based on objective similarity were compared with the ones based on subjective similarity (Fig. 16). Similarity of sound pressure response in the listening room has a close coincidence with subjective similarity. These results imply the necessity of measurements not only in an anechoic room but also in a listening room.

これまでの児童画コンクールの是非をめぐる論議においては,子どもが入選作品をどのように捉えているのかといった,子どもの視点にたった考察が欠けているのではないかと思われる。そこで本稿では,コンクール入選作品を刺激対象として,これらを子どもと教師がどのように評価するのか,また,コンクールの入選作品であるという事実認識が作品の価値判断にどういった影響を及ぼすのかを調査・考察した。結果,子どもと教師の作品評価の枠組みや,標準的な作品イメージを基にコンクール作品の評価を行っていること,子どもの評価枠組みは教師の評価に影響を受けていることなどを示すことができた。

インターネットはこの1, 2年で急速に一般家庭に浸透しつつあり、教育的利用への期待が高まっている。英語教育では、電子メールを取り入れ国際交流などの多くの実践報告がある。また、マルチメディアを駆使し、遠隔地で英会話などの授業を受けられるシステムなども報告されている。ここでは、数学教育の立場からインターネットの教育的利用とその意義と可能性についてさぐってゆく。
