Purpose: The purpose of this study is to exam the effects of a short-term pulmonary program on lung function, exercise tolerance, and quality of life in chronic lung patients. Method: Randomized controlled pre-post test design was used. The outcome measures were forced expiratory volume in one second (FEV1, % predicted), 6 min walking distance (6MWD), Borg score after 6MWD, and Chronic Respiratory Disease Questionnaire (CRDQ). Experimental group performed the 4-week home-based pulmonary rehabilitation program composed of inspiratory muscle training, upper and lower extremity exercise, relaxation, and telephone visit. Patients in control group were only given education about self-management strategies. Thirty four patients with moderate-to-severe respiratory impairment were recruited, and 28 patients (19 in experiments, 15 in control) completed the study. Result: Significant improvements in lung function, exercise tolerance, and health related quality of life were found only in the experiment group. Conclusion: This study yielded evidence for the potential and beneficial effects of home-based pulmonary rehabilitation program in patients with moderate to severe chronic lung disease. The program could be adequately utilized for improvement of health related quality of life in chronic lung patients.

The purposes of this study were to a develop a preventive tailored early intervention program and to investigate the effects of the program on the quality of parenting for low income families. The subjects were eighty five infants, aged 13 to 32 months, and their mothers. Of the 85 mother-infant dyads, 42 dyads were randomly assigned to the experimental group and 43 dyads to the control group. To prevent the risks of the adverse development of infants from low income families a tailored intervention program was created based upon the transactional model. This emphasized the quality of the home environment and of the daily mother-infant interaction. The risk factors were assessed and progress monitoring was undertaken for the preventive tailored intervention treatment. In order to assess the effects of the program, HOME, the NCAST Teaching Scale and the Parenting Stress Index/Short From were used. The collected data were analyzed with descriptive statistics, ANCOVA, and the McNemar test. The experimental group showed a significant increase in performance and higher scores than the control group on the scores from HOME, and the NCAST Teaching Scale and significant decrease and lower scores in the Parenting Stress Index(SF).

Purpose: The purpose of this study was to verify physical and psychological effects of life-oriented forest healing program (LOFH) using urban forests in adults over 40 years of age. Methods: A non-equivalent control group pre-posttest design was used. There were 50 participants in the experimental group and 52 in the control group (a total of 102 individuals). The LOFH was conducted twice a week (3 hours per week) for a total of four weeks. Body composition, psychological states (such as depression and anxiety), and quality of life (QOL) were measured before and after the program. Results: Depression was significantly reduced in the group to which the forest healing program was applied. There was no significant difference in body composition (body mass index, body fat percentage, muscle mass, lean mass), other psychological states (anxiety, mood), or QOL. Conclusion: The LOFH was useful for improving depression in adults over 40 years of age. It is necessary to develop other LOFHs to improve body composition and quality of life.

We proposed a new bit-rate control algorithm to improve MPEG-2 video software encoder. Bit-rate Control plays an improtant role in picture quality of MPEG-2 encoder. To achieve better encoding performance such as controlling picture quality and using bity properly, we proposed a MPEG-2 bit-rate control algorithm using linear average Step-Size. Using a benchmark Program, we compared our algorithm with MPEG-2 Test Model 5. Our proposed algorithm showed better Bit-Rate Control with respect to used bits, picture quality.

Background. Ischemic heart disease results from athesclerotic changes of the coronary artery. These changes are aggravated by hypercholesterolemia, smoking, obesity, lack of exercise, coronary-prone personality, and stress. Because these risk factors affect not only the prevalence of the ischemic heart disease but also recurrence of the disease, cardiac rehabilitation programs were introduced to help patients with ischemic heart disease reduce risk factors. Diverse cardiac rehabilitation programs are needed to motivate participation in cardiac rehabilitation and to enhance patients' quality of life. Objectives. To examine the effect of a self-efficacy promoting cardiac rehabiltation program on self-efficacy, health behavior and quality of life of patients with ischemic heart disease. Methods. Data were collected from 45 hospitalized ischemic heart disease patients. Medical records were reviewed to obtain demographic and clinical characteristics. Data regarding self-efficacy, health behavior, and quality of life were obtained from interviews using structured questionnaires. The nonequivalent control group non-synchronized design was used to conduct this study. One session of conventional group education was given to patients in the control group while they were in the hospital. Patients in the experimental group participated in a newly developed cardiac rehabilitation program. It focused on strengthening self-efficacy with four self-efficacy sources-performance accomplishment, vicarious experiences, verbal persuasion and physical status using two individualized in-hospital education sessions and four weekly telephone counseling follow-up calls after discharge. Results. Four weeks after discharge, the increment of total self-efficacy score was significantly higher in the experimental group than in the control group (p<.0l). There was also a significant difference in the total quality of life scores increments between the two groups (p<.0l). However, no significant changes were noted in the increments of total health behavior scores between the two groups. Conclusion. A cardiac rehabilitation program focusing on promoting self-efficacy was effective in improving self-efficacy, and quality of life of patients with ischemic heart disease.

Purpose: In this study a cognitive enhancement group training program of 10 sessions was provided for communitydwelling elders and the effects on cognitive function, depression and quality of life were tested. Methods: A quasi-experimental study using a nonequivalent control group, pre-post design was used. The participants were 87 elders whose cognitive function was within the normal range. Of these elders, 45 were assigned to the experimental group and 42 to the control group. The intervention was conducted once a week for 10 weeks. Chi-square test, t-test, paired t-test, Wilcoxon rank sum test and Wilcoxon signed rank test were used to analyze the data. Results: After the program, the cognitive function (t=-2.85, p=.006), depression (z=2.82, p=.005) and quality of life (t=2.79, p=.007) of the experimental group was significantly better than those of the control group. Especially, immediate recall (z=2.45, p=.014) and concentration (z=2.58, p=.010) in the subcategory of cognitive function were significantly better than that of the control group. Conclusion: The findings indicate that the cognitive enhancement group training program was effective in enhancing the cognitive function, depression and quality of life for elders and could therefore be considered as a positive program for emotional and cognitive support for community-dwelling elders.

The purpose of this study was to evaluate the multilateral weight control program provided by the university health care center for female college students. The program was 8weeks long and composed of nutrition consultation, exercise, and behavior modification. Nutrition education focused on a low calorie and balanced diet, increasing the intake of protein and micronutrients and reducing carbohydrate and fat consumption. Evaluations were made upon completion of an 8-week program and upon follow-up at 6 months after the end of program. A total of 92 women completed the 8-week program, while 20 completed the follow-up survey. Upon completion of the 8-week program, significant decreases in body weight, BMI, body fat (kg), and %body fat were observed, and muscle mass was also reduced. The total energy and carbohydrates intake were also significantly decreased in subjects with weight loss, while the percentage of subjects whose consumption of protein, calcium, iron, vitamin $B_1$, $B_6$, and niacin did not meet the EAR, were decreased. The blood values of glucose, total cholesterol and HDL-cholesterol were decreased. The follow-up survey revealed that the subjects continued to lose weight after completion of the program. In addition, a Mini nutrition assessment revealed that diet quality improved, especially with respect to reductions in the consumption frequency of fried, greasy and salty food. In conclusion, the multilateral weight control program with diet education for female college students was effective for long lasting weight control and improved dietary behavior. Nutrition education for weight reduction should focus on balanced nutrition as well as lowering the total caloric intake.
