The present study was carried out to examine the hypothesis that ocular surface temperature measured at the site over the iris by an infrared radiation thermometer could be an indication of core body temperature. In healthy young subjects, ocular surface (T_<os>), tympanic(T_<ty>), esophageal(T_<es>), mean skin(T^-_<sk>) temperatures, and local sweating rates and skin temperature of the forehead(T_<sf>) were measured in a chamber controlled at a moderate climate of 28℃-40%(rh) on two separate tests, a passive body warming and an exercise. The passive body warming was induced by immersion of lower limbs in hot water bath regulated 43℃. The moderate exercise was performed with cycle ergometer at the intensity of 80 W. In both tests, T_<os> didn't follow either core (T_<ty>, T_<es>) or shell (T^-_<sk>, T_<sf>) body temperatures. In the second series of experiments, ambient temperature (T_<am>) was raised from 27℃ to 34℃, or lowered from 34℃ to 27℃ for 10 min. In both tests, T_<os> followed the change of (T_<am>) rapidly in spite of the steady T_<ty>, and the change rates of T_<os> were greater than of T_<sf>. When T_<am> was raised slowly from 20℃ to 23℃ for 20 min, the T_<os> rise was almost simultaneous with the T_<am> rise, and there was a high correlation between these two factors (r=0.99). Moreover, the regional thermograms around eyes showed that skin temperature surrounding eyes was significantly higher than T_<os> (p<0.01). These results suggest that ocular surface temperature measured by an infrared radiation thermometer might reflect corneal temperature rather than iris temperature, and could not be an indication of core temperature.

The purposes of this study were to select the crude drugs of the medicated baths calendar for each of the twelve months of the year, and to clarify the physiological responses of this medicated baths. To ultimately establish a set of crude drugs for use in medicated baths, the history and make-up of medicated baths were researched and the characteristics of seasonal events were investigated. Next, characteristics of crude drugs particular to each Japanese season that would affect baths and formulation our bath drugs using readily accessible materials were sought. The result was an assortment of crude drugs specifically designed for effectiveness throughout the year. In experiments, skin temperatures, blood flow, and amounts of perspiration were monitored. The findings revealed that the medicated baths were highly effective in keeping the skin temperature high in that they caused a little decrease in mean skin temperature over a period of time and a longer period of perspiration in comparison to normal bath. These medicated baths were also found to increase the amound of blood flow and the secretion of nor adrenaline, making the drugs a notably more effective promoter of blood circulation than normal bath. The results proved the medicated baths to be beneficial, healthy bathing methods.

Visual stimulation-reaction time and subsequent strike time in the sport of kendo were assessed using electromyographic (EMG) reaction time. Fourteen male college students (kendo athletes (n=7), non-kendo athletes (n=7)) were asked to perform a kendo strikes in response to visual stimulation from a flashing light signal. The strikes employed, the Hiki-Men (HM) and Hiki-Kote (HK), were performed using a bamboo sword, or Shinai, using both of the upper limbs as quickly as possible. The EMG signals from the right (R) and left (L) biceps brachii, the R-, and L-triceps brachii, and R-flexor carpi ulnaris muscles were recorded simultaneously together with the elbow joint angle and hitting shock signals. Total task time (TTT), pre-motor time (PMT), motor time (MT), and action time (AT) were measured for the HM and HK tasks. The photo stimulation body reaction time (BRT) was also measured. Significant strong positive correlations were observed between PMT and TTT for both HM and HK tasks (p<0.01, r=0.93-0.94). Multiple regression analysis was used to determine the contribution of each component of the model in TTT. The standardized partial regression coefficient (β) was significant (P<0.01) for MT (β=0.36-0.38), AT (β=0.49-0.56) and was highest for PMT (β=0.79-0.80). The individual time ratio for PMT, MT and AT to TTT was approximately 50%, 20% and 30%, respectively. No significant correlations were observed between BRT and TTT for the HM and HK tasks (r=-0.02, 0.16). These results suggest that PMT is the most important component contributing to the TTT, and that BRT is not correlated to the TTT in kendo strikes.

In this study, we conducted interviews three times after the Hanshin-Awaji Earthquake Disaster, investigated some problems due to the environmental changes over time after moving into the Temporary Housing, and examined some mental changes in the sufferers. In sofware, friendship was deepened only inside the Temporary Housing, but was separated from the surrounding neighborhood. In hardware, sufferers scarcely felt the facilities improved. With the lapse of time, these problems decreased, but only one problem, "difficulties of household economy", became worse. About the feeling of satisfaction, their dissatisfaction decreased in general. However, with regard to differences of age, the younger generation felt more dissatisfaction than the older generation.
