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

Analysis of surface deterioration of Concrete in Cold Sea Environment by Reliability Analysis

application/pdfPredictions of the service life of concrete structures are an important part of maintenance，management，and durability design. One essential aspect of this is deterioration prediction. The purpose of this study is to theoretically examine the question of deterioration prediction using reliability theory. As an example， reliability theory is applied to the problem of scaling using survey data taken from exposure tests in a cold marine environment. The exposed specimens have a concrete cover of 80 mm， and the scaling deterioration limit is assumed to be 20 mm.　Hazard levels are set up at 1/10 and 1/20 of this limit，corresponding to 2 mm and 1 mm， respectively.　　From this examination, we conclude that the Weibull distribution gives the best fit to the frequency distribution of scaling that exceeds the hazard level in depth. Covariate variables of the reliability function were extracted, and water-cement ratio and Fe_2O_3 were selected for study since their significance level was within 1％. The coefficient for water-cement ratio was found to be negative， while that for Fe_2O_3 was positive. The time taken for scaling to reach the hazard level was found to be approximately the same as required to reach the 50 ％reliability level， thus confirming the validity of this method of reliability analysisdepartmental bulletin pape

オブジェクト指向GISによる地盤DBと微動記録の融合に基づく名古屋地盤構造の解明

地震被害と地盤構造は密接に関係している。しかし地盤の動的物性値に関するデータは量的にも質的にも不足している。従って既往の地盤資料を有効活用するとともに、地震観測記録や微動測定記録などの観測データと相互補完することが重要となる。そこで本研究では、既存の地盤資料をデータベース化して有効活用する地盤モデリングGISを構築し、新たに実施した常時微動記録を融合させて、都市内の地盤構造を構築することを試みた。まず、既往の地盤資料を収集・データベース化し、問題をオブジェクト指向分析した上で、動的地盤モデル構築用の地理情報システム(GIS)を構築した。これにより、名古屋市内の任意の場所での地層断面図の推定、速度構造の推定、重複反射解析による地盤増幅特性の推定といった一連の動作をインタラクティブに行えるようにした。これと併せて、国土数値情報に基づく地盤増幅度の推定式も作成し、地盤データが不十分な地域での方策を検討した。さらに、名古屋市内の計三百数十カ所において常時微動実測を実施し、市内全域での地盤震動特性に関するデータベースを構築した。H/Vスペクトルの周期特性と名古屋市内の地盤構造に基づいて、地盤特性を7つのカテゴリーに分類した上で、微動の卓越周期と地盤モデリングGISにより推定された周期との相関を分析し、両者がおおむね対応していることを明らかにした。また、レーリー波の水平/上下のモード比のピーク周期とS波重複反射解析の卓越周期との相関を理論的に分析した上で、微動H/Vスペクトルの卓越周期から深部地盤の深度推定を試みた。本研究により、名古屋市の地震被害想定の精度が向上し、名古屋圏の適切な防災計画に結びつけることが可能となり、さらには、耐震基準の性能規定化後の地震荷重設定における地盤の増幅特性の適切な評価にも貢献できる。科学研究費補助金 研究種目:基盤研究(B)(2) 課題番号:08455251 研究代表者:福和 伸夫 研究期間:1996-1998年度research repor

X-ray Measurement of Internal Stesses in the Retained Austenite of Hardened Steels

Since retained austenite particles have great influence upon the mechanical properties of hardened steel, it is very important to know internal stresses in the retained austenite phase. However, the retained austenite diffraction line is too weak, so that we have a very great difficulty to measure the stresses. In this paper, applying the all over angles method, we measured the internal tresses of martensite and retained austenite in hardened steels. Moreover x-ray elastic constants of each phase were calculated.departmental bulletin pape
