The present paper deals with obtaining the proper application criteria for the control mode, by using computer graphic simulation, in order to recover the error effectively occurring in the practical supervisory contol work of hyman-robot system. In these experiments the opteations by human and by control program are performed as control modes for recovering the error. And then we compare and analyze tow control modes taking task error and task time as performance measures and task difficulty as a variable factor. Consequently as the task difficulty increases, the task error in the operation by hyman tends to be less than in the operation by control program and the task time is superior in the operation by control program. Therefore, we suggest that two control modes should be used jointly for recovering the error and the operation by control program should be applied in major fraction of control and the operation by human in minor fraction of control.

Purpose: The Purpose of this study was to examine an obesity control program using dietary consult and physical exercise among middle-aged obese women in a health center. Method: This study used a pretest-posttest design. The subjects were 63 middle-aged women with over BMI $25(kg/m^2)$ or %BF 28 who participated in the obesity control program for 12 weeks. Results: After the program for 12 weeks, BMI(p= .02) and TC(p= .00) decreased significantly compared with those before the program. Conclusion: Obesity control programs in health centers can decrease the degree of obesity in middle-aged obese women. Therefore health centers should develop strategies for their members' continuous participation in such an obesity control program.

This study was conducted to reconstitute a family life education program for caregivers and to analyze the system of implementation. Based largely on a pre-existing program for caregiving families, I developed a new educational program. Personal time management and personal needs management were added in the content of the program order to help enhance self-esteem and internal control. The reconstituted educational program, which consists of 6 sessions, was implemented on a small group of caregivers in Jeollabukdo Province who support their elderly parents. The effectiveness of the program was evaluated by a pre-test, a post-test, a follow-up test and open-questionnaire reports. The results from the post-test suggest that the program has been effective in improving the knowledge on aging process, internal control and self-esteem. But the follow-up test results show the program has been effective only in improving the knowledge on aging process. According to the open-questionnaire reports, the program seems to have been effective in improving interpersonal relationships and changing attitudes toward their elderly parents.

The purpose of this study was to evaluate weight control program provided by university health care center for female college students. The program was 8-week long and composed of diet, exercise, and behavioral modification. Evaluation was made on the completion of 8-week program and a follow-up survey was done at 3-24 months after the end of program by telephone or bye-mail. Total of 76 women completed the 8-week program and 51 for follow-up survey. On the completion of 8-week program, significant decreases in body weight, BMI, body fat (kg), ％ body fat, and WHR were resulted, however, no change in muscle mass was found. Even the subjects without weight change showed significant reduction in body fat (kg) and ％ body fat. Total food intake was decreased resulting in reduced intakes of most nutrients. Meal distribution of energy was changed; ％energy from snack decreased from 22％ to 14％, and proportion for breakfast increased. Blood values of hemoglobin, hematocrit, total cholesterol, HDL-cholesterol, LDL-cholesterol, and triglyceride were within normal range, and no changes were observed by this program. The follow-up survey revealed that 88.3％ of the subjects continued to lose weight after completion of the program, while only 7.8％ gained weight. And 78.4％ of the subjects considered the program effective. In conclusion, the weight reducing regime with education is effective for long lasting weight control and health conscious behavior for female college student. Since the subjects reduced the size of meal, instead of cutting only calories down, food selection to meet all the nutrient requirements except energy should be emphasized.

Purpose: This research was conducted to compare the effect of a wellness program on knowledge of obesity and weight loss in women schizophrenia inpatients. Methods: A nonequivalent control group pretest-posttest design was used for this study. A total of 44 patients with schizophrenia were randomly divided into an experimental group (22) and a control group (22) in a 12-week multimodal weight control program. For 6 weeks, the experimental group received approximately an hour of teaching on obesity interventions and for another 6 weeks one hour of teaching on exercise and weight control interventions while the control group received the usual care. The outcome variables were measured before and after the program. Data was analyzed with the ${\chi}^2$-test and t-test using PASW Statistics 18. Results: For those who completed the weight control program, there was a mean weight loss of 1.37kg by the end of the intervention. The experimental group showed significant improvement in knowledge of obesity and weight loss. Conclusion: The wellness program was effective in reducing the weight of women schizophrenia patients as well as being effective in increasing knowledge of obesity. Therefore, nurses must consistently educate women schizophrenia inpatients about health care and knowledge of obesity.

Adaptive Cruise Control (ACC) is one of key features on intelligent Transportation System(ITS). In ACC, the steering is done by a driver, but the engine throttle valve and the brake are controlled electronically. The relative velocity and distance from the preceeding vehicle are measured by radars or image processing units and relevant vehicular spacing is maintained in ACC control systems. In this study, vehicle longitudinal dynamics are modeled to simulate vehicle longitudinal maneuver and to design longtitudinal controllers for ACC vehicles. The control algorithm is designed based on the modeled vehicle longitudinal dynamics using a non-linear sliding mode control method. To verity the performance of the control algorithm, a real time numerical simulation program is developed on a Silicon Graphics workstation using C-language . A real time graphic program is alos develpe and integrated with the numerical simulation program.
