脳炎後，推定７年間にわたる持続性の反復性発話を呈した１例を経験した。症例は発症時22歳，右利きの男性。約７年後の評価時には，日に数回意識減損発作があり，発動性低下，病識低下，脱抑制傾向などの精神症状を認めた。MRI検査では右前頭・側頭・頭頂葉および左側頭葉に萎縮がみられ，また右優位の側脳室の拡大を認めた。神経心理学的には失語および広義の聴覚失認 (言語音，環境音，メロディの聴覚的認知障害) ，さらに自己の発話の著明な反復を認めた。この反復の単位は１音節を主とし，次に単語，複数音節の順に多かった。反復の位置は語中・語尾に高頻度で，語頭はこれに比し少ない傾向があった。本例の反復性発話の臨床症候は語間代にもっとも当てはまると考えられ，語間代は Alzheimer 病に限られるものではないことが示された。

DESIGN C170show that it is able to accurately identify the NCS operators between the various copies and superpose the structures to within 3Å of each other.This algorithm has proven to be rapid, robust and accurate.The performance of the algorithm is as good as or better than previous methods using refined models, despite the fact that this approach uses only a rough approximation of the backbone.
Cypress charcoals, which were prepared with different temperatures and transferring rates under a flow of super-heated steam, were used for the electrode of electric double layer capacitor (EDLC) with 1 M H2SO4 electrolyte. EDLC capacitance of cypress charcoals prepared was about 250 F/g with a current density of 20 mA/g, about 160 F/g with 50 mA/g and about 120 F/g with 1000 mA/g. Capacitance observed was shown to be governed by pore structure of cypress charcoal and was tried to explain by the contributions from microporous and external surface areas. Rate performance evaluated from the ratio of the capacitance measured with 1000 mA/g to that with 50 mA/g was relatively high, about 0.7, for cypress charcoals prepared.
The behavior of deep beams failed in shear with shear span ratio (a/d) of 0.5 was investigated using 3D-RBSM, which is a representative method of discrete method. The analytical results for the beam without web reinforcement were compared with the experimental ones and analysis capability of 3D-RBSM was confirmed. 3D effects were discussed by comparing the change of strut widths and high stress as well as 3D deformed shapes. Then, the effect of web reinforcement was investigated. It was confirmed that, there is no significant effect of web reinforcement in deep beams with a/d=0.5.
本研究は, 格子等価連続体化法構成式を使用して, 地震時の鉄筋コンクリート構造物の挙動を正確に予測する解析ツールの開発を主眼としている. そのため, 本研究ではRC要素内に発生する最初のひび割れに対して, 直交, 非直交の最大計4方向のひび割れが許容できるように構成式の拡張を行った. 構築した構成式を用いて, 正負交番載荷実験, 振動実験を数値解析し, 実験値と比較することで, 本解析モデルの妥当性, 解の収束性, 及び適用性について検討を行った. 加えて, 構成式で使用するパラメータについても検討を行った.
