Recent advances of office automation and information technology cause the increase of the complaint of ocular fatigue, musculoskeletal fatigue and mental fatigue for VDT (visual display terminal) workers. It becomes obvious as problem on industrial safety and health. A quantitative analysis on the stress and fatigue by scientific data is very useful. In this paper, the results of quantitative analysis focused on total working hours with quantitative indexes of HRV (heart rate variability) used on evaluation in autonomic function are discussed. VDT workers group with longer total working hours has different HRV and CVrri (Coefficient of variation of R-R interval) than one of control group. The extent of stress and fatigue may differ with total working hours.

In this paper, the chronological trend of studies on shadow education in the sociology of education in Japan was examined. Based on this examination, future directions are then presented for consideration. Shadow education has been noted as a factor in the relation between educational achievement and social stratification in the 1970-80's in Japan. In the 1990s, based mainly on national survey data, it was found that educational investment and strategy influenced shadow education. Later, in the late 2000s, the amount of research and case studies that focused on shadow education increased. Currently, by controlling endogeneity biases, studies have been conducted in an attempt to identify causal effects of shadow education. In conclusion, for future consideration, within research on shadow education, it is necessary to clearly distinguish between the different terms used for shadow education (“out of school education”, and “private supplementary tutoring”) within the Japanese language.
