This study aims to clarify the realities of the moving out of the residents after the land reajustment project following the great Hanshin-Awaji earthquake. We made a questionnaire of the residents in the Misuga-nishi district, Kobe City where the project was enforced. Clarified points are as follows: 1) The population of the district is 60 percent of pre-earthquake and 60 percent of current residents have moved in from outside the district. 2) Half the number of the residents who moved out maintain a relation to the district where they had lived before the earthquake. 3) Details of the moves of the residents are varied and lasted for an unstable residence period of varing lengths. Only the residents who owned their own houses were able to evade an unstable residence period. 4) The residents who had an unstable residence period depended on facilities and human relations in the district where they had lived before the earthquake. Moreover, they evaluated the environmental characteristic as high. The difference of the dependency on community support influences the achievement level of the residents in reconstructing their lives.

This study will track the reconstruction process of the urban area devastated by the Great Hanshin-Awaji Earthquake and clarify how the change of characteristics of houses/urban districts has affected the "isolation" of residents. We made a questionnaire survey on the residents in the public housing at the Tsukiji district, Amagasaki City where the Residential District Improvement Project was enforced. Clarified points are as follows: 1. Family units that moved in to the public housing from a detached/row house showed a larger percentage of "isolation" than the ones from an apartment house. 2. The degree of "isolation" differed according to what floor the residents lived. Family units living in the 1st-2nd floor showed a smaller percentage of "isolation", but the ones living in the 3rd floor upper showed an extraordinary larger percentage of "isolation". 3. What can control "isolation" is to have a chance of a natural exchange with the vicinity residents. An intentional plot to urge an exchange will not function well for the already "isolated" residents. A space design, which secures an exchange with residents on a day-to-day visual/traffic line base, is required.

This article is a study to consider the way of reconstruction by the Collective Relocation Project after a disaster. We conducted a questionnaire for residents who experienced the project. The results were as follows: 1) There are multiple types of collective relocation. The problem of relocation of the whole village is that there are residents who chose to move based on a negative motive. But public housing was supplied by the project and this supported the relocation of low income residents. 2) The problem of spotty partial collective relocation is that some residents must remain because of economic reasons. Remaining residents generally showed a lower intention of settlement. 3) It is important for adopting the Collective Relocation Project to make clear whether relocation of the whole village is unavoidable and to support the relocation of low income residents who want to move.

Digital modulation methods such as QPSK and QAM have been studied for efficient transmission of digital signal such as MPEG through analog lines. Among such modulations, 64QAM has been getting attention for building CATV system because of its effective transmission capability. In order to implement 64QAM transmission system for consumer tuner, biggest obstacle could be phase noise. In this paper, we assume phase noise spectrum of tuner and studied the influence of these spectra to BER of 64QAM system both theoretically and experiment. In conclusion, we obtain a method to astimate the BER based on the phase noise spectra condition.

<p>In this study, we clarify the actual conditions and backgrounds of isolated deaths at temporary housing and recovery housing in disaster area, conducting statistical analyses based on death certificates. The results are as follows, 1) The ages of those who die alone are higher at recovery housing than temporary housing. At recovery housing, it also takes longer for discovery. The main reason for this is young people under age fifty with isolation risks such as remaining unemployed and single. 2) At temporary housing, family and neighbors mitigate the isolation risks, while their roles decline at recovery housing. 3) Location of recovery housing has little connection with isolation of disaster victims. One of the factors seems to be that the isolated condition has already been established before moving into recovery housing. Community-conscious safety nets should be in place especially in the early stage of restoring stable living.</p>

A molecular dynamics simulation was carried out in order to investigate a peculiar permanent densification phenomenon for SiO_2・K_2O・CaO・SrO glasses of an invert composition, i.e., the fraction of SiO_2 lower than 50 mol%. The phenomenon was previously observed by an experiment by high pressure treatment: the densities of permanently densified glasses exhibit a maximun value at 3 GPa (Kawamoto et al., J. Non-Cryst. Solids, 284, 128(2001)). In our simulation, the density profile was qualitatively reproduced: the density after decompression exhibits a maximum at treatment pressure 12 GPa. After decompression, the five-and six-coordinated Si species, which promote a network at high pressure, remain mostly at treatment pressure of 12 GPa, where the density exhibits a maximum.

Mt. Apoi (810 m above sea level, N 42°07', E 143°02') is located in the southern part of the Hidaka mountain range. Many alpine plants are distributed along the ridge, despite its relatively low altitude. From a botanical viewpoint, this mountain has a number of special and interesting features due to the abundance of endemic plants. The following factors may contribute to the growth of alpine, endemic and relic plants at low altitude : (1) Reduction of solar radiation as well as air temperature by fog in the summer. (2) The bedrock of Mt. Apoi is ultrabasic rock (olivine). The physical and chemical characteristics of this soil and rock environment are unfavorable for plant growth, and are the cause of the abundance of endemic plants on Mt. Apoi (Watanabe 1970, 1971). The alpine meadow plant community of this area has been altering as a result of invasion of woody plants over the last 40-50 years (Watanabe 2001). In the present study, we investigated the process of invasion of Pinus pumila and Pinus parviflora var. pentaphylla (a pioneer woody plant) in this alpine meadow by measurement of tree age. The special soil environment (ultrabasic rock) in the investigated area has helped to maintain the special alpine meadow on Mt. Apoi. The delicate relationship between the soil environment and alpine plant growth will be affected by global warming and/or acid rain, resulting in a rapid decline in the distribution area of the alpine meadow.

郵政省通信総合研究所(CRL)は, 技術試験衛星V型(ETS-V)に搭載された移動体通信実験機器(AMEX)の特性を定期的に把握するために定期チェックアウト(C/O)を1988年4月に第1回目を実施し, 1996年3月までに7回実施した.測定によって得られたAMEX中継器の特性を, 打上げ前に実施された地上最終電気性能試験の値と比較することで, 静止軌道上にある中継器利得の経年変化を評価した.これは今後の衛星搭載中継器開発における使用部品の品質保証等の信頼性設計に資するものとなる.

安心・安全な社会の実現のため非常災害時における確実な通信手段の確保の必要性が叫ばれている.これらの社会的機運の高まりをうけ、地上通信と衛星通信を統合した新たな共用端末のためのモバイル衛星通信システムの検討が開始されている.これは、地上の携帯電話と同等程度の小型端末で直接衛星との通信を可能とすることにより、地上通信と衛星通信を同一端末で実現するシステムである.通信衛星に大型展開アンテナを搭載し、サービスエリアを数多くのマルチビームで覆うことにより、衛星側の通信能力を飛躍的に高めることや、地上の携帯電話と同一周波数帯の使用を実現することで可能となる.本稿ではこのシステムについて紹介し、技術的課題について述べる.

1994年打上げ予定の技術試験衛星VI型に搭載して我が国初の衛星間データ中継実験を行うSバンド衛星間通信用アンテナ(SIC)について述べる.SICは衛星搭載としては世界初のオンボードビーム形成マルチビームフェーズドアレーアンテナであり,電気的にビーム走査を行い複数の周回衛星(ユーザ衛星)との間で同時にデータ中継することができ,また,オンボードマイクロプロセッサを用いてユーザ衛星の位置を計算し自動的にビームを向ける,などの特徴を有している.オンボードビーム形成方式は米国のデータ中継衛星の方式に比べて我が国のようにユーザ衛星が比較的少ない場合に周波数と電力の有効利用が図れるなどの利点を有する.本論文ではまず,SICの機能・構成について述べ,つぎに温度変動等に起因する位相・振幅誤差の影響を含めたアンテナ解析について述べる.更に,主要コンポーネントとして新たに開発した広帯域マイクロストリップアンテナ,小型で位相誤差の少ないビーム形成回路,ユーザ衛星の軌道計算を行う移相器コントローラについて述べる.最後にSICの搭載モデルの総合試験結果を述べる.
