車椅子エルゴメータの開発

本研究の目的は車椅子駆動時の発揮トルクやパワーを直接測定可能にするための車椅子エルゴメー夕を開発することである。平成9年度は設計の基本コンセプトについて検討し、それに基づいた設計を行ない、試作機を完成させ、実動テストを行なった。平成10年度は完成した試作機の基本性能の検討を行なった。本研究で開発した車椅子エルゴメータは2本のローラーの間に車椅子を乗せ、ローラーに負荷トルクをかけることにより車椅子駆動時の負荷を発生させる仕組みになっている。この場合、通常の路面や床面と比べ、無負荷時の駆動抵抗である残留抵抗(残留負荷)がやや大きくなることが明らかになった。また、この残留抵抗は車椅子に用いられているタイヤの種類やキャンバー角、乗員の体重を含めた車椅子の総重量等によっても異なることが明らかとなった。したがって、生体側から見た駆動時の実負荷はベルトの摩擦によって加えた設定負荷と残留負荷との和となる。そのため、残留負荷を知ることができなければ駆動中のパワーを正しく計算することができない。そこで、本研究では設定負荷0の状態で人が乗車した車椅子をエルゴメータにのせ、駆動用のローラーをモーターで回転させて、その時に必要なトルクを測定することにより残留負荷を計測する装置(トルク検定器)を開発した。また、このトルク検定器を用いることにより、負荷の設定精度の検討も行えるようにした。異なる種類の車椅子に重りを乗せることにより総重量を変化させ、一定速度で駆動用ローラーを回転させたときのトルクを実負荷として実測した。設定負荷と実負荷の関係を検討したところ、両者の間の直線性は高く、残留負荷の測定さえ行なえば十分な精度で駆動パワーの測定が可能であることが明らかとなった。科学研究費補助金 研究種目:基盤研究(B)(2) 課題番号:09558003 研究代表者:池上 康男 研究期間:1997-1998年度research repor

Relationship of immunonutritional factor with changes in liver volume after portal vein embolization

application/pdfBackground To identify predictors of changes in hepatic volumes after portal vein embolization, we examined the relationship with preoperative nutritional and immunological parameters. Patients and Methods Ninety-three patients who underwent portal vein embolization were included. The control group comprised 13 patients who underwent right hepatectomy without portal vein embolization. Computed tomographic volumetric parameter was measured for changes in embolized and nonembolized liver. Correlation with various candidates of immunonutritional parameters was examined. Results Difference in increased liver ratio was 9.1%. C-reactive protein levels significantly increased after portal vein embolization （P  0.92 and increased liver volume ≥ 10% tended to correlate with lower prevalence of severe complications. Only increased intraoperative blood loss ≥ 1,500 mL was significantly associated with morbidity and mortality （P < .05）. Conclusion Contrary to our hypothesis, immunonutritional parameters, except C-reactive protein and C-reactive protein/albumin ratio, did not reflect hypertrophy after portal vein embolization. Although it is difficult to predict the hypertrophic degree, the strategy of scheduled hepatectomy should be switched in case of impaired inflammatory status after portal vein embolization

Experimental Study on the Deterioration Prediction of Concrete Structures

application/pdfThe purpose of this study is to analyze the deterioration mechanisms that affect the required performance (specifications critical to the operability) of concrete structures. A technique based on deterioration prediction is introduced which should prove useful in the maintenance and management of structures. Neutralization and chemical attack were selected as two exampｌe mechanisms.　Neutralization　was examined in terms of its effect on reinforcement corrosion and bearing strength，while the effects of chemical attack on strength， esthetic appearance， and bearing strength were studied. A deterioration limit was established for the ultimate state of structures with a safety factor of 1.15. Deterioration was predicted about flexural strength. In this way， a prediction method of neutralization and chemical attack was defined by arranged factor of deterioration. Flexural strength of neutralization was predicted by rate of neutralized thickness. Flexural strength of chemical attack was predicted by rate of strength deterioration.departmental bulletin pape
