This study was undertaken in order to examine the relationship of self-efficacy, control, perceived health status. self-esteem, social support, and demographic characteristics to health promoting lifestyle of college students, and to determine factors affecting health promoting lifestyle of college students. The subjects were 92 students of one university in Taejon. The instruments used for this study were a survey of general characteristics, health promoting lifestyle(44 items), self-efficacy (28 items), self-esteem(10 items). control(8 items), perceived heath status(1 item), and social support(12 items). Analysis of data was done by use of mean, percentage, t-test. ANOVA, Pearson correlation coefficient and stepwise regression with SAS program. The results of this study are as follows. 1) The average item score for the health promoting lifestyles was low at 2.30. In the sub-categories, the highest degree of performance was interpersonal support(2.90), and the lowest degree was exercise(1.67). 2) Male students showed a significant higher score in exercise subscale than female students. Students who had more income had higher scores in self actualization subscale. Students who's family had experienced severe disease had higher scores in health responsibility and interpersonal support subscale. Students who had experienced exercise had higher scores in total health promoting lifestyle, exercise, interpersonal support, and stress management subscale. 3) Significant correlation between perceived health status and self-efficacy, perceived health status and self-esteem, control and self-efficacy, control and self-esteem, control and social support, self-esteem and self-efficacy was found. 4) Self-efficacy and control revealed significant correlations with total health promoting lifestyle and all subscales of health promoting lifestyle except self actualization, A significant correlation between perceived health status and self actualization subscale was found. Self-esteem revealed significant correlations only with self actualization and interpersonal support subscale. 5) Significant correlations were found between most of the subscales of total health promoting lifestyle. 6) Self-efficacy was the highest factor predicting health promoting lifestyles of college students (30.55%). Self-efficacy and control accounted for 36.55% in health promoting lifestyle of college students.

In this study, muscle activity was measured using surface EMG (sEMG) during a voluntary maneuver (ankle dorsiflexion) in the supine position was compared pre and post gait training. Nine patients with incomplete spinal cord injury participated in a supported treadmill ambulation training (STAT), twenty minutes a day, five days a week for three months. Two tests, a gait speed test and a voluntary maneuver test, were made the same day, or at least the same week, pre and post gait training. Ten healthy subjects' data recorded using the same voluntary maneuvers were used for the reference. sEMG measured from ten lower limb muscles was used to observe the two features of amplitude and motor control distribution pattern, named response vector. The result showed that the average gait speed of patients increased significantly (p〈0.1) from 0.47$\pm$0.35 m/s to 0.68$\pm$0.52 m/s. In sEMG analysis, six out of nine patients showed a tendency to increase the right tibialis anterior activity during right ankle dorsiflexion from 109.7$\pm$148.5 $mutextrm{V}$ to 145.9$\pm$180.7 $mutextrm{V}$ but it was not significant (p〈0.055). In addition, only two patients showed increase of correlation coefficient and total muscle activity in the left fide during left dorsiflexion. Patients' muscle activity changes after gait training varied individually and generally depended on their muscle control abilities of the pre-STAT status. Response vector being introduced for quantitative analysis showed good Possibility to anticipate. evaluate, and/or guide patients with SCI, before and after gait training.
