The purpose of this study was to investigate the relationship between the shape of the spinal column and the deflection in the segmental and body center of mass during quiet standing in elderly individuals. Sixteen elderly individuals were recruited in this study. Their thoracic kyphosis and lumbar lordosis angles were measured using a spinal column-measuring instrument. Further, we determined the deflection characteristics of the segmental center of mass at the landing phase by using a three-dimensional motion analysis system. A significant positive correlation was observed between the thoracic kyphosis angle and the velocity of anteroposterior deflection in the center of mass of the whole body and head. These results suggest that increase in the thoracic kyphosis angle is associated with the deflection characteristics of the whole-body and head centers of mass during quiet standing.

This study investigated the effect of different light intensity of the morning on dim light melatonin onset (DLMO). The subjects were 22 males (age: 20-24 years old). They were exposed to the light conditions for three hours in the morning (09:00 - 12:00). The light conditions were three light intensities (1500, 3000, 6000 lx). DLMOs were evaluated by saliva samples which were taken every 30 min from 20:00 to 1:00. The light exposures of 3000 and 6000 lx in the morning advanced the DLMOs. However, the advancing effect may depend on their lifestyle.

To gain a better understanding of the adaptive evolution of human skin pigmentation, we combined genetic engineering, remote sensing, and geographic information systems in a new approach for detecting gene-environment interactions. Previously, we detected natural selection on haplotypes of the OCA2 gene that had been revealed by SNP analyses. In this study, we analyzed ultraviolet radiation data obtained from satellite records. These results were subjected to a spatial statistical analysis technique for analyzing gene-environment interactions. The results suggested that skin color variations may be affected by mutations induced by ultraviolet radiation. These findings are consistent with the hypothesis that global variations in skin pigmentation may have resulted from localized adaptations to different ultraviolet radiation conditions via natural selection.
