<Original Article> Age-Related Changes in the Spontaneous Motor Activity during the Dark Phase in the Male Mouse

Spontaneous motor activity was studied in first generation (F1) hybrid C57BL/6 x C3H male mice at the ages of 6, 18 and 36 months. Activity was recorded for 10 consecutive hours during the dark phase, using a capacitance-induction motility monitor. The recordings were taken simultaneously at 2 levels of sensitivity; total activity (T) for the fine and gross movements and large activity (L) for the gross movements. The data were measured in 1 hour intervals and then stored on discs for micro-computer analysis. The T activity decreased with age. Changes in the mean hourly scores of T and L activity with time during the 10 hour dark phase differed among the 3 age groups. The results suggest that spontaneous motor activity during the dark phase is a useful parameter of changes in the motor function in aged mice.journal articl

成長ひずみ法による円筒コイルばねの素線断面形状最適化解析

Optimum cross sections of cylindrically coiled spring are analyzed by the growth-strain method. this method was previously proposed as a shape optimization method which deforms shapes by generating bulk strain. In the present analyses, the helix angle is neglected. The stress distributions are analyzed by the finite element method based on the stress function. The growth deformation is analyzed by the finite element method on the assumption of a roll of coil as a rotationally symmetric ring under free restriction. The bulk strain is generated based on the strain energy density in a manner in which volume change in the cross section is absorbed in the circuit direction. In consequence, a convergent curve of mass improvement ratio and corresponding cross sections are obtained. The cross sections are egg-shaped tapering to the outside of the coil.journal articl

Why did Executives of Local Companies Enter Graduate School of Local University?

application/pdfIn 2008, 7 executives of local companies entered the Graduate School of Medicine of Mie University. They were young executives or backbone executives who succeeded to the business and were thinking of doing a new trial in their suc-ceeded business. At the first stage of our challenge, each ex-ecutive brought their own problems in research and develop-ment to University and discussed their own possible technical solution with a professor who supervises them. This individual approach was effective but not enough for their expected hopes as the reward of time and efforts which they spend at Univer-sity. We then tried the other approach to satisfy their purpose of entering a University. Since their wish was to find out the own way in their succeeded business, we started the cross dis-cussion meeting in which all executive students and other graduate students participated. We indicated the activity, which executives bring both of the problems regarding man-agement and R&D of their company and discuss these matters with other executive student and professors in a University, is effective for the foothold which works out a management strategy for the executive. In this reports, we discuss a possible activity which will be effective for regional innovative from a local University.departmental bulletin pape

Characteristics of Price Fluctuations in High Frequency Foreign Exchange Data

Abstract Since price fluctuations of financial time series like stocks or foreign exchange rates are highly random, it is generally said that arbitrage chances do not exist. In the triangular trades, however, arbitrage chances are observed in the real data analysis of very short term price fluctuations. Also, such chances survive for surprisingly long terms. Moreover, we have found that price fluctuation of foreign exchange rate is not independent of its history but is strongly correlated to the previous movements for about three ticks. In this paper, we discuss on the above two points and show that foreign exchange rate is not perfectly random and have many characteristic features.departmental bulletin pape
