To assess the physiological responses of subjects with differing personality traits to the artificial lighting environments, we examined the effects of four lighting conditions on cognition taste thresholds and saliva secretion in relation to subjects' personality types (Type A vs. B behavior pattern and the State-Trait Anxiety Inventory) in 40 healthy men. The physiological responses to light differed between the Type A and Type B subjects and among the high-, middle- and low-scorers on a trait anxiety test. We next studied the nonvisual effects of blue-pulsed light, and we observed that the nonvisual effect of pupillary constriction (miosis) occurred even during blue-pulsed light irradiation at very short pulse widths. When the product of irradiance intensity and the pulse width were equal, the condition of high irradiance and short pulse width was shown to produce marked miosis.

Several million years have passed since a subset of primates became humans. Because we spent more than 99.99% of our evolutionary history in natural environment, it is considered that we are essentially adaptive to nature. However, we live in a society characterized by urbanization and artificiality despite our physiological functions still being adapted to a natural environment. According to the concept of evidence-based medicine, we reviewed preventive medical effects of nature therapy, which comprised forest, park, wood, and flower therapy. We collected scientific data from field and laboratory experiments using physiological indicators. We expect nature therapy to play an increasingly important role in preventive medicine in the future.

The number of community-dwelling elderly people in Japan is increasing. Osteoporotic fractures are significant health problems that lead to increased health care costs, impaired physical functioning, difficulties in activities of daily living (ADLs), and worsening of health-related quality of life of elderly people. Osteoporotic fractures have also been related to premature death. Age-related low bone mass as well as increased bone resorption are the two major risk factors for osteoporotic fractures. In this paper, we will discuss physiological characteristics in associations of bone mass, bone resorption and osteoporotic fractures with difficulties in ADLs and mortality.

Although physiological polytypism is affected by a variety of genetic and environmental and cultural factors, there were few studies of examine relationship between physiological polytypism and gene polymorphism in physiological anthropology. To clear a part of the effects of genetic background to physiological polytypism, we focused the importance of mitochondria and mitochondrial genome. Since mitochondria are considered to have played an important role in cold adaptation, we examined relationship between physiological response and mitochondrial haplogroup during cold exposure. In results, mitochondrial haplogroup affected some physiological parameter (oxygen intake, rectal temperature, etc.). These results suggested that physiological polytypism affected by genetic background.

This paper is an attempt to deal with the origins and formation of the Japanese language, in the light of mostly linguistic aspects of the neighboring languages, such as Old Korean, Old Chinese, Proto-Austronesian, and some archeological aspects. This notion is also based on a linguistic theory that the Japanese is formed through time with language contacts with the neighboring languages mentioned above. This also discusses the particular aspects of language contact of each language and language family in order to suggest that Japanese has been formed by language contacts with those languages.

We examined the relationship between ladder exercise and reaction times of the upper limbs and whole body in preschool children. The participants were 167 children, aged 4-6 years, who practiced ladder tasks for 4 months. Thereafter, they completed a ladder achievement test. In addition, they performed three types of reaction-time tests (pushing a switch, removing their hands from the switch, and jumping to a mat in front of them). Relationships between the ladder scores and the three reaction-time test results were significant and relatively high (R = 0.707). In particular, the standard partial regression coefficient for whole-body reaction time (-0.417) was significant (p < 0.05). Therefore, ladder exercise may be particularly effective for developing various reaction movements of children in recent times.
