A fluid temperature measurement technique based on fluorescence polarization is developed and applied to measure the two-dimensional temperature distributions in microchannel. In this measurement method, the fluorescence depolarization due to rotational Brownian motion of the fluorescent molecules in the solution is measured and converted to fluid temperature. Since the fluorescence polarization degree is independent to fluorescence intensity, the measurement is less influenced by the fluorescence quenching effect, which is an issue in laser-induced fluorescence (LIF) method. Experiments were performed using a microchannel with fluorescent molecules solved in water. The effects of the fluorescent molecule concentration, fluid pH and fluid temperature on the fluorescence polarization degree are discussed to evaluate the influence of the quenching effects and to derive the correlation curves. Furthermore, the proposed method was applied to measure the temperature distribution with linear gradient generated in the microchannel. The results showed that the fluorescence polarization is considerably less sensitive to quenching factors compared with the fluorescence intensity measurements. A linear correlation between the polarization degree and the fluid temperature was obtained. This relationship agreed well with the theoretical one. Further, measurement of two-dimensional temperature distribution in the microchannel agreed well with the values obtained by the thermocouple measurements. These results confirmed the validity of the measurements and feasibility of the proposed method.

46歳男性. 痛風にて平成13年7月より benzbromarone(商品名: ユリノーム) を処方された. 平成14年1月に肝機能障害と黄疸が出現し, 劇症化が危惧され, 当院紹介入院. ウイルス感染, 自己免疫疾患, 代謝性疾患が否定され, 本薬剤による薬物性肝障害と診断した. 入院後, 肝性脳症が出現し, 劇症肝炎の診断にて人工肝補助療法を開始したが, 肝不全が進行し死亡した. 死亡時の肝組織像では軽度の炎症細胞浸潤を認め, 薬物性肝障害に矛盾しない所見であった. 本薬剤による肝機能障害の発生機序は不明とされているが, 今回の症例にて本薬剤と中間代謝産物の血中濃度測定を行ったところ, いずれも著明な高値を示したことより, 薬物代謝異常が原因である可能性が示唆された. また, 本症例のように服用開始6カ月以降でも重篤な肝機能障害を発症するため, 長期にわたる肝機能検査が必要であり, 異常を認めた場合には薬剤の減量, 中止を考慮することが重要と考えられた.

Taiwan was Japan's first colony and was held under its control for 51 years until the end of World War II in 1945(20th year of Showa Era)At the early stages of Japan's possession of Taiwan, the administration was not without its critics and as a result much discussion on the issue was provoked among experts within Japan. By analyzing propaganda written about Taiwan and coloniescommunicated via media for women in the period extending from the mid to late Meiji Era, it is theintention of this essay to elucidate the significance that the possession of Taiwan as a colony had onthe female Japanese population of the main islands of Japan at that time.The messages that were observed in the analysis can be divided into the following three categories:(i) there would be a possibility that Taiwanese women could be assimilated into Japanese societythrough an emphasis on their similarity with Japanese women; (ii) Japanese women would beexpected to exercise an influence on the women form less well-developed Asian nations includingTaiwan; and (iii) for successful colonial management, Japanese women would be expected tomigrate to Taiwan accompanying their husbands and to establish a happy family life there. From the above-stated findings, it can be concluded that Japanese women bore the responsibility ofrepresenting the idea of home and roles of the good wife and wise mother of a contemporary familyin order to enlighten Taiwanese women and maintain colonial management in a stable andsustainable state as a national project.

Recently, recalls for mass production products such as car components have been frequently reported even for the case that the rate of defects is only of the order of ppm or less. The objective of this paper is to propose the solution to avoid the recall problem of the order of ppm for mass production products. Even if the defect rate is of the order of ppm or less, most of remaining safe products have to be recalled and be replaced by new components. Such a recall causes a great cost deficit if the very rare defect is possibly related to fatal accident. However, it is very difficult by the conventional quality control methods to find the defects of the order of ppm or less at the stage of design and production. This paper proposes a new practical quality control method to avoid the defects of the order of ppm or less for mass production products based on the statistics of extremes which has been successfully applied to fatigue strength evaluation of defective materials. First, several examples of the quality control method to avoid the troubles mainly caused by failures and damages of components will be presented. Next, it will be shown that the same approach also can be applied to other problems such as the optimum control of operational parameters and the selection of optimum materials through the index based on the statistics of extremes. It will be also shown that the same method can be applied not only mass production components but also to avoid the troubles and failure accidents for large machine components of small number production. The stress-strength model approach will be reviewed from the viewpoint of the statistics of extremes.
