血液透析患者の転倒リスクを予測するうえで有用な指標を明らかにする. 歩行可能な血液透析患者123例を対象に転倒の発生を主要アウトカムとする1年間の前向きコホートを実施した. 身体パフォーマンスに関する指標であるshort physical performance battery (SPPB), 筋力, 筋肉量に加え, 栄養状態の指標や透析に関連する指標の転倒に対するハザード比を算出した. 観察期間内に38名 (31%) が転倒し, 透析関連低血圧 (intra-dialytic hypotension : IDH) が独立した危険因子として抽出された (HR=2.66, p=0.01, Log rank test p=0.002). また, SPPB 7点以下は11点以上と比較して有意に転倒のリスクが高かった (HR=2.41, p=0.02, Log rank test p=0.021). IDHやSPPBの低下は透析患者の転倒リスクを予測するうえで有用な指標となることが明らかとなった.

Generally, grinding fluid is supplied from a nozzle to a grinding point. However, it is difficult to supply sufficient coolant to the deep grinding point of a hole. Therefore, we have proposed an alternative coolant system that supplies grinding fluid from the inner side of the grinding wheel utilizing the spindle through the supply system of the machining center. In this study, a new tool for small and deep holes was developed to supply grinding fluid in this way. The inside of a 0.45%C steel cylinder was then machined under various grinding conditions. Higher form accuracy and surface roughness were obtained under all conditions by supplying grinding coolant from the inner side of the grinding wheel. In addition, the system prevented tears on the machined surface and loading on the grinding wheel.

The paper will describe the architecture of the Computing Surface 2 (CS-2) Meiko’s second generation MPP supercomputer system. The paper will begin with a brief overview of the architecture before describing the programming environment in detail.
