    It is useful to be able to evaluate objectively the progress of learning in order to realize effective learning systems fitted to individual capabilities. Such systems decrease the load of learning and increase the effectiveness of learning. In this paper, we select "Event Related Potentials" as physical indexes to represent the progress of learning. The progress of learning is measured by the response time which takes for the test subjects to answer properly the given problem. Several variables of Event Related Potentials are defined as candidates for the indexes. The suitable variables are picked up as effective indexes by the results of "Multiple Regression Analysis". Through these results of discussions, this paper will clarify that the deep relationships between these indexes and the progress of learning.

    The purposes of this study were to clarify the characteristics of growth and development of physical fitness with age, and to examine the influence of the difference of habitual exercise on physique and physical fitness of male students at a National College of Technology. A total of 132 males enrolled in 2001 were administered physique and physical fitness tests for three years. The 5 physique tests and 9 new physical fitness tests developed by the Ministry of Education, Culture, Sports Science, and Technology of Japan were used The participated students were classified into 4 groups based on the frequencies of their exercise enforcement for three years. The mean differences were examined using two-way analysis of variance of one-factor repeated measurements. Body linearity and body bulk become larger with age, but the influence of exercise enforcement frequencies on physique was low. It is considered that the continuous exercise enforcement contributes to an increase of muscular power, agility, muscle endurance, and whole-body endurance, and an effect of continuous exercise with age is marked in muscle endurance. However, the influence of the continuous exercise enforcement on improving static strength and flexibility is not high. The lack of exercise by adolescent students may produce a decline of whole-body endurance, muscle endurance, and agility in spite of the growth period.

    This study examined the placebo effect of hyperoxic gas inhaled after exercise on respiratory rate and heart rate variability(HRV) and determined the possible psychological contribution of the hyperoxic gas inhalation. Eight healthy male subjects participated in two experimental sessions on two different days; one day using the placebo gas, the other day a control session. Each day the subjects pedaled on a bicycle ergometer at 65% VO_2max for 10 minutes, and after the exercise, took a 20-minute rest where the respiratory curve and electrocardiogram were measured. A spectral analysis analyzed the heart rate variability and the autonomic nervous activity. A questionnaire was used to determine subjects' feelings of effectiveness of the gas inhalation. The high frequency component of the HRV power spectral density in the session with the placebo was 16.5% higher than that without the placebo during the 5 minutes after the exercise, but this was not statistically significant. There was no statistically significant difference in heart rate and the respiratory rate between the two conditions. The questionnaire results indicated no significant correlation between the positive image of a refreshing effect of the hyperoxic gas with the respiratory rate, or with the autonomic nervous activity. These findings suggest that there would be no positive psychological effect on restoration from fatigue with the hyperoxic gas inhaled after exercise.

    We have focused the spontaneous rhythmic skin blood flow fluctuation on forehead (the oscillation, main frequency 0.1 to 0.2Hz) measured with the laser doppler flowmetry as an easy and useful physiological index. The purposes of this study were to estimate the relation between the oscillation and autonomic nervous activity and we tried to evaluate that the oscillation can distinguish similar mood states. 10 male subjects were induced to the two mood states (relaxed and bored) with audio visual and physical stimuli. Mood state of each subject was evaluated with the profile of mood states (POMS). The skin blood flow, ECG and electrogastrogram (EGG, main frequency 0.05Hz) were measured simultaneously. At the relaxed state, the oscillation and EGG were increased significantly than the resting condition (P<0.01). It was suggested that the oscillation was effected parasympathetic nerve activity. And we have found that relaxed and bored state was can be distinguished with combined the oscillation, HR variability and EGG.

    The purpose of this study was to examine the skin hydration and life style of Japanese and Korean women. I used a Moisture checker to measure the hydration status of 2 facial spots, on the forehead and cheek of the face, and on the upper arm in each of the seasons from 2002 to 2003. The results were analyzed by using a three-factor (nationality, site and season) analysis of variance (3-way ANOVA), and post hoc analysis was performed using a Scheffe multiple-comparison test. The level of statistical significance was set at p<0.05. The results were as follows: 1) The Japanese showed a higher hydration than the Korean women in spring and a lower hydration in summer on their faces. On the seasonal changes, there was a significant difference between Japanese and Korean women on their faces. The Japanese showed significantly higher hydration in fall than in other seasons. On the other hand, Koreans showed higher hydration in summer and lower hydration in spring. 2) The Japanese women showed a lower hydration than the Koreans in fall and winter on their upper arm. On the seasonal changes, there was no significant difference between the Japanese and Korean women. Both the Japanese and Korean women showed the highest hydration in summer and the lowest hydration in winter.
