Objective: This study attempted to find out if it changes the child's ability to perform daily life activities when visiting the familiar environment and daily living space of children with cerebral palsy and conducting a home activity support program for children and parents. Design: Randomized Controlled Trial Methods: Among 22 children aged 3 to 12 years old, they were assigned to the intervention group and control group. Of these, 12 boys and 10 girls participated in the study. Gross motor function measure and upper extremity function evaluation were used to measure the physical function of children with cerebral palsy, and self-care skills, mobility and social functions were evaluated in the pediatric evaluation of disability inventory. In addition, a parenting sense of competence was used to find out the efficacy of parents in raising children. After the pre-evaluation, basic rehabilitation treatment and intervention programs were applied to the intervention group, and only basic rehabilitation treatment was performed to the control group, and post-evaluation was performed 8 weeks later. Results: As a result of the study, among the items that measured the gross motor function, upper limb function, and daily life performance ability of the intervention group in the difference between the intervention group and the control group, statistically improved in personal processing and movement (p<0.05). In addition, the parenting sense of competence children in the intervention group was statistically significant (p<0.05). Conclusions: The home activity support program will help strengthen the ability of cerebral palsy children to perform daily life as a way to set mutually agreed goals with their families or children and achieve them in a familiar environment.

In this paper, we apply a support vector machine(SVM) that incorporates an optimized nonlinear decision rule over different sets of feature vectors to improve the performance of statistical model-based voice activity detection(VAD). Conventional method performs VAD through setting up statistical models for each case of speech absence and presence assumption and comparing the geometric mean of the likelihood ratio (LR) for the individual frequency band extracted from input signal with the given threshold. We propose a novel VAD technique based on SVM by treating the LRs computed in each frequency bin as the elements of feature vector to minimize classification error probability instead of the conventional decision rule using geometric mean. As a result of experiments, the performance of SVM-based VAD using the proposed feature has shown better results compared with those of reported VADs in various noise environments.

This study analyzed the relationships between positive attitude, leisure attitude, and leisure satisfaction among university students participating in a leisure activity support education program using the metaverse. The results are as follows. First, positive attitude was found to have a significant impact on leisure attitude. Perspective diversification influenced the cognitive and emotional factors of leisure attitude, self-acceptance influenced the emotional factor, and social adaptation influenced both the cognitive and emotional factors. Second, leisure attitude was found to have a significant impact on leisure satisfaction. Cognitive and emotional attitudes influenced all factors of leisure satisfaction, while behavioral attitude primarily influenced the relaxation factor. Third, positive attitude was found to have a significant impact on psychological, social, relaxation, and physiological factors of leisure satisfaction. Perspective diversification and self-acceptance played important roles, while social adaptation influenced all factors of leisure satisfaction. These findings provide important implications for the curriculum design of leisure activity support education programs using the metaverse for university students, focusing on enhancing positive attitude. The metaverse environment offers experiences similar to real-life interactions, which can contribute to enhancing participants' positive attitude and improving their leisure satisfaction. Program design should include elements that enhance participants' self-acceptance and social adaptation abilities, as well as focus on improving self-regulation skills. Through this, university students can enrich their leisure experiences, ultimately contributing to improving their overall quality of life.

Objectives : The present study was designed to investigate effects of Ssanghwa-tang (Shu$\bar{a}$nghu$\bar{a}$-g$\bar{e}$ng) on oxidation/reduction reaction-related and aging-related enzymes $in$ $vitro$. Methods : We performed MTT assay, collagenase inhibition assay, elastase inhibition assay, tyrosinase inhibition assay, DPPH free radical scavenging assay, SOD-like activity and xanthine oxidase (XO) inhibition assay. Results : The 50% ethanol (EtOH) extract of Ssanghwa-tang (SHT) showed 55% inhibition of collagenase activity, and 42% inhibition of elastase activity at 1 mg/ml concentration. Also it's treatment showed 18% inhibition of tyrosinase activity, to relate whitening effect, at the same dose of 50% ethanol extract of SHT. Antioxidant activities were determined by DPPH radical scavenging, XO inhibiting activity and SOD-like activity. These scavenging, XO-inhibiting and SOD-like activities were measured in 80%, 75%, and 28% inhibitions, respectively, at a 1 mg/ml treated dose, compared to those of control. The inhibitory effects of 50% EtOH extract on aging and oxidation-related enzyme activities were higher than those of water extract and 95% EtOH extract. Conclusions : Taken together, our findings suggest that the SHT has potential and applicable benefits for development of cosmetics to have anti-aging (anti-wrinkle and whitening) and anti-oxidation functions.

The purpose of this study is to compare the level of health-related quality of life and relating factor between institutional elderly and community living elderly. The subjects were 390 from Sanatorium or Nursing home and 467 from the community in Kwangju. The results are followed : 1) A comparison of ADL between two groups, institutional elderly and community living elderly, resulted in that community elderly were more significantly independent in the areas of bathing and transfer than institutional elderly. 2) A comparison of IADL between two groups resulted in that : Community elderly were more independent in the areas of using telephone and transportation, food preparation, house keeping, and doing laundry. Institutional elderly were more independent in the area of handling finances. 3) In the case of poor health-related quality of life, institutional elderly showed 2.4 times in the dimension of physical fitness, 1.8 times in daily activity, 2 times in social activity, 2 times in pain, 26.7 times in social support, and 0.4 times in subjective quality of life higher than community elderly There was no significant differences in the rest of dimensions. 4) In institutional elderly, the analysis of variables related to the health-related quality of life resulted in that; The relating factors were sex, education, and chronic illness in the dimension of physical function. Direct contact with family or significant others in the dimension of social activity. Chronic illness in the dimension of pain and perceived health status. Direct or indirect contact with family or significant others over the phone or through letters in the dimension of social support. 5) The analysis of variables related to the health-related quality of life showed that community elderly has more relating variables in each area than institutional elderly. The relating factors were age, sex, and chronic illness in the dimension of physical function. Education and chronic illness in the dimension of emotional status. Age and chronic illness in the dimension of daily activity and social activity Education and chronic illness in the dimension of pain and perceived health status. Sex, education, family size in the dimension of social support. Education and chronic illness in the dimension of subjective quality-of-life. Throughout general daily activity, community elderly showed more satisfactory results than institutional elderly, but in the subjective area of health-related quality of life, such as subjective quality of life, institutional elderly group showed more positive results. And community elderly had more relating factors than institutional elderly. For the health care of the elderly that focused on quality of life, new approaches considering the characteristics of both group, institutional and community living elderly, are needed.

Using 492 older people in Chuncheon, this study examines whether social support is associated with depression of older people. Findings show that stress is positively associated with depression. Social support is negatively related to depression of older people. Analysis on the sources of social support reveals that all of the supports from families, friends, and important others are negatively associated with depression of the elderly. However, buffering effects of social support is not confirmed. Depression of older people is also associated with gender, household type, economic activity participation, and chronic diseases. Based on the findings, this study provides suggestions to prevent depression of older people and future research agenda.

The study aims at exploring a general trend of psychological well-being (PWB) of elderly volunteers and analyzing the variables which give effects on their PWB. The subjects were two hundred men and women over 60 years old currently participating in voluntary service. The data collected from interviewing were analyzed by descriptive statistics, $x^2$ test, Pearson's correlation and hierarchical multiple regression. The main results are: First, PWB of the elderly is higher than the average score of PWB. Second, the elderly's generativity is positively related to PWB. Family support such as an emotional and instrumental support was also positively related to PWB. Third, the variables effecting on PWB of elderly volunteers were education level, participation frequency, generativity level, and an instrumental support of their family members on it. The lower their educational level was, the more frequently they participated in voluntary activity, the higher their generativity level was, and the more support given from their family, the higher PWB scores they showed.

This study examined the relationship between parental efficacy, marriage satisfaction, social support, neighborhood context, and parental involvement in preschool children's education in low income families. Total 460 low income parents' data about parental efficacy, marriage satisfaction, social support, neighborhood context, and parental involvement are collected from the data of index studies for Korean child and adolescent's development in 2009. Parental efficacy, marriage satisfaction, perceived social support and perceived neighborhood context correlated positively with parental involvement. Regression analysis detected different patterns of association between these variables and the three dimensions of parent involvement. Perceived neighborhood context was associated with child care involvement, while parental efficacy was the most influential factor related to child leisure involvement. Marriage satisfaction was the strongest factor influencing involvement in children's educational activity. These results support the validity of a multi-dimensional, ecological conceptualization of parent involvement in low income families.

Purpose: This study aimed to analyze the conditions of the leisure type, health status, self-esteem, and social support of the elderly living alone. Method: The subjects were 189 elderly. The instrument was a structured questionnaire. The data were analyzed by descriptive statistics, ANOVA, and Pearson correlation coefficient. Results: The frequency of the leisure types of the elderly living alone was in the order of culture, rest, social activity and sports. The following factors showed a statistically significant relation: gender, education, religion and marital status with leisure type; age, economic status, job and leisure type with perceived health status; education, economic status and religion with self-esteem; and economic status, marital status and religion with social support. There was a negative correlation between ADL and both perceived health status, and self-esteem, but positive correlations between self-esteem and perceived health status, and between social support and both perceived health status and self-esteem. Conclusion: To maintain the quality of life of the elderly living alone, this study suggests that providing various leisure activities could raise self-esteem, and thereby complement for any deficiencies in family and social support.
