PURPOSE
The purpose of this study was to identify the effects of taekwon aerobic on obesity indices and cardiovascular risk factors in middle-aged obese women.
METHOD
Data were collected from 19 middle-aged obese women who participated in taekwon aerobic exercise. This research adopted one-group pretest-posttest design. Taekwon aerobic was applied 3 times in a week for 12 weeks, and the obesity indices and cardiovascular risk factors were checked before and after the program. Body weight, BMI and % body fat for obesity indices were checked, and total cholesterol, triglyceride, HDL-cholesterol and the ratio of total cholesterol/HDL-cholesterol for cardiovascular risk factors were measured. The data was analyzed by paired t-test using SPSS/Win 10.0.
RESULTS
There were significant differences in body weight, BMI and % body fat after the taekwon aerobic exercise. There was a significant difference in total cholesterol. However, there were no significant differences in triglyceride, HDL-cholesterol and the ratio of total cholesterol/HDL-cholesterol after the taekwon aerobic exercise.
CONCLUSION
This study showed that taekwon aerobic exercise decreased obesity indices and lowered total cholesterol in the cardiovascular risk factors. The results of this study show that taekwon aerobic exercise is effective in enhancing the health of middle-aged obese women.

This study was conducted to identify correlations among internet games addiction (IGA), self-esteem and physical health in middle school students.
METHODS
A total of 428 middle school students were selected through simple random sampling. Data were collected from the 15th to 30th of March, 2006. Data were analyzed using SPSS/PC program by frequency, chi2-test, t-test, ANOVA, Duncan test, Pearson's correlation coefficient, and Stepwise Multiple Regression.
RESULTS
1. According to the results of analyzing the degree of IGA, the addicted group was 1.9%. 2. Analysis of IGA according to the general characteristics showed that there were statistically significant differences in on-line friend, using time and major leisure. 3. Analysis of physical health according to the general characteristics showed that there were statistically significant differences in on-line friend and off-line friend. 4. IGA was in a significantly negative correlation with selfesteem. 5. In the results of regression, using time was identified as a factor influencing the IGA.
CONCLUSION
Considering the results above, we need to develop IGA prevention programs to enhance physical health and self-esteem and to control using time.
