高密度運転線区の列車制御システムにおいては,高輸送力,高安全性,高信頼性が求められる.従来は,固定した区間ごとに列車の存在を検知し,そこに列車を進入させるかどうかの判断により,各列車の速度を地上の集中制御装置で求め,それを各列車の自動列車制御装置 (ATC) に指示していた.このため,高密度輸送は難しかった.本論文は,各列車が,自らの位置検知を行い,地上からは停止する位置のみを列車に伝送し,それに基づく列車速度の決定と制御を自律的に行う自律分散型 ATC システム (D-ATC) を提案した.更に,システム全体の運行を妨げず,D-ATC をもつ列車の段階的投入と,既存の ATC をもつ列車とを共存させながらのオンライン稼動中のテストを保証するアシュアランス技術を提案した.段階的投入に対する二つの方式として,車上統合/車上分離技術を示し,これらをアシュアランス性の面から評価した.この結果をもとに,JR 東日本の山手・京浜東北線用の列車制御システムで実用化した.

In order to prevent the mine pollution caused by the acid mine drainage (AMD) from abandoned metal mines in Japan, the treatment of AMD has been conducted with neutralization using a significant number of reagents. Passive treatment processes are attractive as an alternative because of an energy and cost saving one. Although the passive treatment processes using sulfate-reducing bacteria (SRB) have been investigated widely in the United States and Europe, many of those processes require a huge area that is necessary for a long hydraulic retention time (HRT). So, in this research, the mechanism, influential factors and performance of metal removal using SRB have been investigated in the column test to develop it as a prospective, effective and compact process. The results showed that sulfate reduction by SRB had continued for 140 days under the condition of a 50-hour HRT, and that metals had been removed as sulfides in a column. In addition, it is apparent that the positions where each metal sulfide was precipitated were different. This means that the quality of AMD is an important factor when the treatment facility is designed.

小児気管支喘息を持つ親又は保護者が記入する,身体,社会,家族,感情,個人の発展の5つの項目からなるQOL (quality of life)調査票を作成した.回答は最大の支障を1点,支障なしの5点の5段階評価とし,4歳未満は23問,4歳以上は31問とした.本報告は初診時のデータに基づき,反復再現性等の信頼性,因子的妥当性を検討した.2週間発作発現の回数が安定していた喘息患児,4歳未満8例,4歳以上26例の級内相関係数は0.879,0.793を示し,再現性を示した,喘息患児102例,健常児40例,感冒等の罹病中の非喘息患児12例のQOL総合点のCronbachαは0.6329〜0.8829で内的一貫性を示した、喘息患児の個人の発展項目以外の身体,社会,家族,感情との関連質問の回答は健常児と比べ有意(p<0.05)に低下した.因子分析により,QOLを構成する5つの項目および項目内の各機能が累積寄与率60%以上で確認され,本QOL調査票は再現性,構成上の信頼性,因子的妥当性を有し,経時的な治療法のなかで調査票の適用が可能と考えられ,喘息管理と治療目標のあり方を検討する上で有用な調査票と考えられた.

This paper is based on two field research projects done during December, 1997, and September, 1998, in Naha and Nago, focused on women who led associations formed against the construction of a new helicopter base in Henoko, Nago City and a referendum on the issue. It is worth mentioning that the civil movement against the creation of the new base had a significant impact on the referendum, which was held on the 21st of December 1997. Especially, many grassroots associations led by women played an important part. One of the main purposes of this paper is to look at this civil movement from the perspective of gender. Furthermore, it is meaningful to look into the movements of women in Okinawa, since these women's movements have engaged in the distinctive activities and have had a distinctive spirit because of the fact that such women live with military bases all around them. The study of Okinawan women will show a different side of the women's movement since the situation of women in Okinawa is different from that of women in the rest of Japan. The approach to issues involving women has moved gradually from the "equal rights for women" movement to "gender analysis" ever since de-jure, or legal, equality between women and men was secured by local, national, and international women's movements. The issue moved from "equality" to "integration", "empowerment" and "gender analysis in the mainstream". The movements connected with the Nago referendum, however, looked somehow different from this general trend of women's issues. Women's associations in Nago were based on the coalition of "individual" women. Those who had never been involved in civil movements started to associate and created a network all over Okinawa. They identified themselves as "mothers" or "housewives" to evoke the sympathy and compassion of the rest of the community. That approach created both risks and opportunities for future civil movements as well as for women's associations in Okinawa. One of the risks is that the use of the notion of "mother"as the basic characteristic of women could create a spirit inside the woman which separated them from other non-mother women and from men. The opportunities arise the new perspectives that women brought to the US military base issue in Okinawa. The human rights perspective given by the associations of women is that the military bases constitute a structural violence against humanity which constantly threatens the people in Okinawa. That deepens and widens the struggle against the military bases, which has traditionally been fought against illegal land use. These women's movements also opens new connections with other issues related to the military bases, such as environmental problems, economic development, eco-tourism, and violence against women. Women who have not joined in the coalition of the traditional network can easily advocate "alternatives" to presentday society. This is not a sudden movement of Okinawan women. Rather, this is part of a continuous appeal of women, it has simply just begun to be seen and heard in society. Women have been doing active work for many decades, but the results have become more and more visible in the recent years of "change". The situation is still changing, and so this study should be continued.
