One male and eleven female subjects were examined in order to compare their ventilatory and heart rate responsiveness to hypoxia at rest and during moderate exercise (60 W) .
1) The slopes of the ventilatory response curve to hypoxia (AVE) were 306.5±229.5 and 1, 082.9±928.3l⋅min^-1⋅mmHg at rest and during exercise, respectively. Significant difference (p<0.05) between the two groups was found.
2) The slopes of the hypoxia-heart rate response curve (A_HR) were 704.9±477.3 and 1, 165.5±587.8 beats⋅min^-1⋅mmHg at rest and during exercise, respectively. The latter was significantly greater than the former (p<0.05) .
3) A significant relationship between AVE and AHR was observed (p<0.05) .
4) The relationship between ΔV_E50 and ΔHR₅₀, the increments of ventilation and heart rate from room-air to end-tidal Po₂ 50 mmHg, was also significant (p<0.01) .
These results indicate that hypoxic ventilatory and heart rate responsiveness during exercise is significantly greater than at rest, and point to the highly synergistic nature of the relationship between respiratory and cardiac regulations.

Medical university students were divided into 5 types according to the process they used to decide on a course when entering a university, and the relationship between the decision-making process and occupational identity after entering the university was examined. The largest number of students, approximately 50%, were of the “meeting” type, followed in descending order by the “early decision” type, the “changing during 4 years” type, the “deciding at the last moment” type, and the “avoidance” type. There were differences in the frequency of decision-making types among departments, including the nursing department, which showed a large number of students of the “early decision” type. We examined the relationship between the decision-making process and occupational identity after entering the university and found that students of the “early decision” type were stable after entering the university, whereas students of the “avoidance” type had the lowest scores on all 4 subscales of occupational identity. This tendency was seen during the 4 years of university, and the importance of deciding on a course when entering the university was indicated.
