The purpose of this study was to evaluate the validity of two different measures of physical activity under normal living conditions. The 24-hour physical activity diary method (24 HD) and accelerometer (Lifecorder) were analyzed. Total daily energy expenditure (TDEE) and daily varia tion of energy expenditure (EE) were compared employing the two measures in conjunction with the minute-by-minute heart rate method (Flex HR) in middle-aged people with a mean age of 57.9 yr (N =17), and in young people (college students) with a mean age of 23.5 yr (N=11) . The TDEE as measured by the 24HD and Lifecorder was 2576.4±514.7kcal·d^-1 and 1973.1±290.2kcal·d^-1 respectively. The TDEE as measured by the Flex HR method was 2718.3±625.5kcal·d^-1. The TDEE as measured by the Lifecorder method was significantly lower than that of the Flex HR method (p<0.01), The correlation coefficient (r) for the 24 HD and FlexHR measured values for TDEE (kcal/day) was 0.64 (p<0.01), and that for Lifecorder and Flex HR was 0.38. The daily variation of energy expenditure pattern measured by Lifecorder was similar to that of the Flex HR ; 24 HD measurements, on the other hand, were slightly lower than Flex HR measurements during the afternoon period. The 24 HD method was reasonably accurate in the testing. The daily variation of energy expenditure measured pattern by Lifecorder was similar to that of the Flex HR method ; but the fact that the TDEE results were underestimated suggests that the Lifecorder method has merit in the measurement of daily activity patterns. It follows from this that to improve measurement of the TDEE, it is necessary to modify the Lifecorder method of calculating the algorithm,

This is a report of the activities of the committee on medical student selection 1994-1996, particularly focused on the 15th Conference on Medical-Student Admission held 1996/8/31 with the subjects of social needs and influences upon high school education for the purpose of improving student selection system in Japan. We must consider how largely admission tests have being influenced high school students at the time of decision making, what medical schools they submit their applications to, and what ability the society or community requires physicians, for creating better system of evaluation for admission in Japan.

We report a case of hemangiopericytoma of the soft palate of 60-year-old patient, who noticed a mass of the soft palate and experienced difficulty in speaking. We found a pediculate, hard, elastic mass measuring 38 mm (cross-sectional diameter). Computed tomography (CT) scans and dynamic magnetic resonance imaging (MRI) confirmed irregularly shaped mass and revealed a heterogeneous internal composition, consistent with vascular tumors. We excised the tumor under general anesthesia. Histopathological diagnosis was based on positive immunoreactivity of CD99 and vimentin and weak, positive staining of CD34. Three and half years following tumor excision, there is no recurrence or metastasis.
