社会経済データ多目的空間検索表示サーバシステム

Google Earth［1］， NASA World Wind［2］により，従来一部の研究者の対象であった地球の情報が，インターネットの普及と共に，急速に一般化している。地球表面の画像から得られる様々な情報を解析する試みは，航空機搭載カメラ等により地球観測衛星の打ち上げ以前から行われているものの，人口動態など画像以外のデータと組み合わせて，インターネットを通じて連携する情報を空間検索表示するサーバシステム事例は少ない。さいわい先進諸国では，社会経済センサスデータが小地域メッシュ等の形で，また主要幹線道路位置も（xi, yi）値の座標組として整備されている。この論文は，地球情報単体の表示のみならず，各種の地点データを空間検索して，多様な結果をクライアントに外部サーバの情報と共に表示するサーバシステムの実装に関する開発事例を紹介する

Comparative double-blind trial of KN-7 tablet and Robaveron injection in the treatment of neurogenic bladder

37施設で, 神経因性膀胱233例を対象に, ロバベロン注射剤を標準薬とし, KN-7錠剤の経口投与による排尿障害に対する有用性を, 二重盲検群間比較試験で比較検討した.解析対象例はKN-7群108例, ロバベロン群107例である.KN-7群は1日6錠投与した.改善度の効果判定では改善以上K群40.7%, R群38.7%, やゝ改善以上それぞれ76.9%, 72.6%と有意差はなかった.臨床所見中改善の良かった項目は, 尿意, 残尿感, 尿失禁, 排尿までの時間, 排尿時間, 尿勢-排尿力と尿線中断の改善などで, これらの改善以上はK群35.8%, R群30.8%で, 有意差はなかった.副作用はK群0.9%, R群6.8%, K群が有意に少なかった.両剤とも主として下痢で, R群ではその他頭痛, 頻脈, 肝機能障害, 発熱感などを少数例認めた.臨床検査値ではGOT, GPTの上昇が2例あった.有用度有用以上はK群46.3%, R群45.8%で有意差はなかった.疾患別では, 末梢神経疾患, 膀胱の性状では弛緩性, 時期では12ヵ月以内の例で特に改善率が高かった.以上から, KN-7錠剤は, ロバベロン注射剤に比べ, 同等の効果が期待でき, 安全性も高く, 長期投与あるいは外来患者の治療にも適するThe clinical effectiveness, safety and usefulness of KN-7 tablet as a new oral application of the prostatic extract, on urinary dysfunction of neurogenic bladder were compared with those of Robaveron injection by the double-blind test method. In the study, 2 tablets t.i.d. and a shot of intramuscular injection 1 ml a day were given successively for 3 weeks. A total of 233 cases were reported from 37 facilities belonging to the KN-7 Clinical Research Group. Some of them were excluded or dropped out. The number of cases used for analysing the effectiveness, safety and usefulness were 214, 232 and 215, respectively. There was no bias between the two groups with a significant homogeneity in the background. In the overall clinical effectiveness, the effective rate including excellent, moderate and slightly effective was 76.9% with KN-7 and 77.4% with Robaveron. In the clinical usefulness, the rate of usefulness of slightly useful or above was 75.0% with KN-7 and 75.7% with Robaveron. There was no significant difference between the two groups in the clinical effective and useful rates at a significant level of 5%. Side effects were observed in 1 of the 114 (0.9%) patients given KN-7 and 8 of the 118 (6.8%) patients given Robaveron. The incidence of adverse reactions with KN-7 was significantly lower than that with Robaveron. Based on the results, it was concluded that KN-7 tablets, 2 tablets t.i.d., would be as effective and useful as a Robaveron injection 1 ml daily and safer than the latter in the treatment of neurogenic bladder

大型ヘリカル装置のIC聾アンテナと加熱特性

Ion－cyclotron heating was applied to the Large Helical Device by using single, trap loop antennas located at the outward side of the toroid. Good experimental results were obtaine with adequate plasma　confining configurations and antenna conditionings．Loading resistance of the antenna was2－8Ohm and　this was a sufficiently large value. Various heating characteristics were investigated by changing the　heating modes, ion species and magneticfield configurations．The minoriy-ion heating mode resulted in the best heating performances，and the heatin gcharacteristics largely depended on the cyclotron resonance positions．There were some unique features due to the heliotron configuration．These results showed the　effectiveness of the ICRF heating in a helical device and the appropriateness of the ICRF antenna design　in the LHD
