A number of studies on electromagnetic wave emission from fractured rocks have been heretofore carried out. By many authors it was pointed out that rock fracturing or acoustic emission could be concerned with electromagnetic wave emission. However, the origin of electromagnetic wave emission is still not well understood.In this study electromagnetic wave from rocks was measured with a radio interference measuring apparatus during uniaxial compression testing under several kinds of loading conditions.Firstly, the uniaxial compression testing under constant strain rate of 10-4 s-1 was conducted for seven rocks. It was found that Inada granite, Honkomatsu andesite and Kuzuu dolomite emit electromagnetic wave. However electromagnetic wave cannot be detected for Sanjome andesite, Akiyoshi marble, Kimachi sandstone and mortar.Secondly, electromagnetic wave emission was investigated under several experimental conditions. It was found that Inada granite emits electromagnetic wave during uniaxial compression testing under a constant strain rate of 10-5 s-1 and under a constant rate of (stress-strain / Young's modulus).In most cases, electromagnetic wave emission was accompanied with sudden decrease of stress. By analysis on results of the uniaxial compression testing under constant strain rate, it was found that electromagnetic wave emission is closely related to cracking or crack extension.The main results in this study can be summarized as follows;1) Amplitude of electromagnetic wave is relatively large for strong rock.2) For Inada granite, the larger the stress drop occurred in uniaxial compression test is, the larger the amplitude of electromagnetic wave.

本論は、地域コミュニティ活性化を目的としたフリーマーケットについて、京都市内の3つの事例を挙げ、構成主体(空間管理者・主催者・出店者・利用者)の認識を通じてその特性を明らかにし、今後の課題を検討した。その結果、出店者・利用者はフリーマーケットのコミュニケーション・レクリエーションの場としての意味を共有する関係にあり、その中で一般市民・素人の出店が重要な役割を担っていること、そしてこうした特性を支えるためには、既存の露店組合等による管理とは異なる幅広い出店者層の受入れと、管理運営や出店者構成における地域横断的な出店者ネットワークの活用、地域組織等の地域資源の活用が重要であることが明らかになった。

This study suggests a new direction for how a consumer behavior is described on a brand community as the Internet community. The brand community is a specialized, nongeographically bound community, based on a structured set of social relations among admires of a brand. The concept of brand community consists of three aspects : shared consciousness, rituals and traditions, and a sense of moral responsibility. In this paper, the brand community is classified into two types. One is the enterprise based brand community and the other is the consumer based brand community. The former is building for the profit by enterprises ; on the other hand the later is building for the nonprofit by consumers. Each type is characterized in order to clarify the orientation of consumers. Then the other applicable measurement which is shown by the degree of consumer involvement is applied for establishing a matrix of two dimensions. One coordinate axis is named a type of brand community, the other one is a degree of consumer involvement. Finally, the types of consumers on the brand community are extracted four categories as type A, type B, type C, and, type D. Type A is on the enterprise based brand community and on the high consumer involvement. Type B is on the consumer based brand community and on the high consumer involvement. Type C is on the enterprise based brand community and on the low consumer involvement. Type D is on the consumer based brand community and on the low consumer involvement. The finding is that type B has a remarkable process to build the consumers attitude on the brand community.

This paper aims 1) to summarise what kind of research has been developed under what analytical viewpoints in the last 25 years of the Japan Academic Society for Educational Policy, 2) to try to present the basic framework of education policy analysis to contribute to our future researches. The subjects of consideration are the special issue manuscripts and the submitted manuscripts from the Bulletins No.1 through No.24. Eijiro Arai was engaged in task 1), and Hiroko Hirose in task 2). Generally, the research trend was to respond to the changing natures of policies and society. However, it has also been pointed out that the theoretical framework does not catch up with the changes. It is urgent to build a fundamental framework to grasp education policies comprehensively, replacing the outdating Theory of People’s Right to Education. One of the dominant directions may be the expansion of the vision that Isao Kurosaki raised; that is the assemblage of the Sociology of Educational Administration by Munakata Seiya and the Educational Administration Theory by Eiichi Mochida. Keywords: analysis of education policies, fundamental framework, Seiya Munakata, Eiichi Mochida, Isao Kurosaki

JR山陽本線は、出陽鉄道によって1888[明治21]年11月1日、兵庫・明石駅間開業以来100年以上を経てきている。その間、様々な鉄道構造物が建設、改築され現在に至っているが、これらの鉄道構造物の中には古レールを用いた構造物をいくつか見ることができる。<BR>その古レールも、関西地方の鉄道会社が発注したものが多いが、中には横浜鉄道といった還隔地のものも見られる。また、初期はアメリカを中心とした外国からの輸入のみであったが、1910年以降は国産も見られ、1930年以降は国産のみとなっている。

Following Jonai Jutakushi, we recorded interviews with seven individuals at Jonai Jutaku (城内住宅). The first interviewees were Mr. and Mrs. Nakao. Mr. Nakao has experienced air raids on both Tokyo and Fukuoka (Tokyo Daikushu and Fukuoka Daikushu). He made aircraft parts for sea planes at the underground factory in the Wajiro Mountains as a part of the labor mobilization campaign (Kinro Doin). The trial flights of the completed sea planes were conducted at Gan-no-su airport, but most of the aircraft were duds and didn't fly. The second couple interviewed was Mr. and Mrs. Yoshida. Mr. Yoshida fled Pusan, losing everything his family owned in the process. In addition, after he returned to Japan, his older brother died. The next interviewee was Mr. Matsuda, who was mobilized for labor as a coal stoker on a steam locomotive (蒸気機関車石炭くべ). He also witnessed air raids on Fukuoka, and his brother was killed in the field. There was a large old nettle tree in Jonai Jutaku. At one time this area had been a drill court and the nettle tree was the marker for foot races. Those who came in last had to run another lap. The soldiers have strong memories of this tree. The fourth interview was conducted with Mr. and Mrs. Kobayashi. They were asked about their memories of the Fuku-Haku area(福博地域) in Fukuoka City during the Taisho and Showa periods.
