Many types of luminous phenomena were observed at the 1995 Hyogo-ken Nanbu earthquake (Kobe earthquake) of January 17, 1995. A questionnaire survey was done regarding luminous phenomena in order to determine 1) spatial distribution of eyewitnesses of luminous phenomena; 2) origin-times and duration-times of the phenomena; 3) properties of lights, such as color, shape, and brightness.Out of 798 people surveyed, 31 answerers (3.9% of the total) reported that they had observed luminous phenomena. Characteristics of the phenomena may be described as follows; a) More than 50% of the eyewitnesses were within 10km of the epicenter of the main shock. b) Almost all observations of the phenomena occurred simultaneously, or at a maximum of 2-3 minutes from the arrival of the seismic wave to the eyewitnesses' location. c) The duration-time of the phenomena was less than 30 seconds. d) The gross form of luminescence was a belt of light or curtain shape. e) The colors of luminescence were white, blue, and orange, while blue-white was predominant.

Since islands of Okinawa was incorporated into Japan, many Okinawan people have been in a little difficult position. For example, the migrants from Okinawa in the cities of mainland Japan (Hondo) were often discriminated in the employment opportunities. And because islands of Okinawa was ruined in World War II, many Okinawan migrants were left in the mainland, and they had to live in the postwar severe situation. In this paper, I will examine the urban lives of Okinawan migrants in Hyogo prefecture (especially postwar Amagasaki, Takaradsuka, Itami and Kobe city) and their various forms of networks, groups and places to live in and to resist oppressed situation. The association of people from Okinawa prefecture (Okinawa-Kenjinkai-Hyogoken-Honbu) was one of the most cohesive group, it was made by `Okinawa' as a social category and as a symbol of concentration for some social and political purposes. In Amagasaki and Takaradsuka city, these cohesions like Kenjinkai had made it possible for some assemblymen who were native of Okinawa to win the local elections, for example. When the people who lived in the concentrated areas had some political purposes, these areas became the cohesive places to resist their opponents. But these cohesions were ad hoc. Because each migrants lived in different geographical and social context, their each individual living strategies and tactics were complicated, and each migrants had extended their own personal networks which included neighbors who were not native of Okinawa. So even in their concentrated areas, their individual social and political senses were not always in unison. Okinawan migrants had become urbanites in urban settings. It is said that discrimination in the employment opportunities was to some extent eased in the high-growth period, so their lives have changed for the better. And the main role of Kenjinkai have become enhancing mutual friendship.

In local election, most candidates get votes from their home district. This is called "friends and neighbours effect" or "local effect" in electoral geography. But candidates of citizen groups, as one of the new political movements, perform election activities and get votes across large area, becase they are supported by the network of various people beyond existing community power structure. The candidates of organized party, the Japan Communist Party and the Komeito, build strong relationships to his/her neighbours, in the process of strategic assignment of party members' votes to them. This paper surveys the relationship between candidates of citizen groups/the Japan Communist Party and his/her home district in Amagasaki city council election, 1997. In this election, four candidates of citizen groups claimed whole municipal issue, council reforming, as in the last election (1993). They not only maintained and newly constructed broad network of citizens, but this tme they also did locally-oriented election activities. There were two reasons why they regarded each home district as importnat. i) Three of them who had won the last election build relationship to their neighbours during their term of office, and ii) many voters wanted their local representatives because of the influence of the Great Hanshin-Awaji Earthequake (1995) etc. However the candidates' attitude toward home district and their spatial spheres of election activities varied considerably. These factors affected each scope of votes and even the electoral results. This paper illustrates the assigned zones of the Japan Communist Party. These zones determined the spheres of votes of the candidates and enabled them to get solid votes. Additionally, in the official gazette for election, the candidates promised to consider local interests to the neighbours of their own zones.

本発表では,主に1984年制定の尼崎市都市美形成条例を対象として,その運用例や,市の財政難などにともなう運用上の変化を確認する。同条例は「狭義」の景観行政に関わるものであり,今回の発表ではその部分に焦点を当てる。ただし「まちづくり」全般と関わる「広義」の景観行政にも必要に応じて言及する。 その際には,行政(や研究者)による「都市」表象との関係にも留意する。自市をいかなる「都市」と見なすかによって,その時々の行政の在り方は変容する。都市景観行政は「都市」それ自体が置かれた複雑な流動的状況や,その時々のトレンドにに左右される「都市」表象を色濃く反映するのである。 より具体的な事例の内容としては,1980年代以降における尼崎市の狭義の景観行政の整理,旧尼崎城下町の一角を占める「寺町」を中心とした景観行政の注力とその変化,それを裏付ける市財政における景観行政の位置づけの変化などを取り上げる。脱工業化,バブル崩壊,阪神大震災の影響といった広範なコンテクストの変化の中で様々に変化してきた景観行政は,「市民派」市長のもとで決定的に弱体化されていき,自他ともに「市民」と認めるであろう寺町住民と行政との間で「寺町マンション建設問題」という形でのコンフリクトを生じせしめるに至る。この間に尼崎市は,「独自の歴史を有する個性ある都市」との表象から,「大阪大都市圏における住宅都市」というようにその表象を大きく変容させている。 都市景観行政論を幅広い都市論の中に置き直して再考することが最終的な目標となるが,この発表それ自体では,尼崎市都市美形成条例に関する詳細な事例の紹介を中心におこないたい。

日本海の鳥取県沖の海域と陸域での観測を連携させた電場・磁場観測を実施した。観測は、1)鳥取県と兵庫県の県境付近沖の海域を含む測線と、2)隠岐諸島周辺海域の日本海を含む測線で実施した。これらの測線に沿って、海域では海底磁力電位差計、および海底地電位差計を用いた観測を、また、陸域では、長周期電場・磁場観測を実施した。得られた広域比抵抗構造モデルによると、陸域では上部地殻が高比抵抗領域、下部地殻が低比抵抗領域として検出された。さらに日本海下深部に低比抵抗領域が見出された。
