The purpose of this study was to investigate the structural relationship between the elderly's participation in exercise, cognitive function, and life satisfaction. The participants of this study consisted of 2491 elderly people who were the subjects of the 2017 elderly survey. The measuring tools were the cognitive function scale and the life satisfaction inventory. Participation in exercise used exercise time for one week. The collected data was analyzed through SPSS and AMOS 18 version. The results of this study were as follows. First, exercise participation was found to have a positive effect on the cognitive function of the elderly. Second, participation in exercise had significant effect on the life satisfaction of the elderly. Third, it was found that the cognitive function of the elderly had a positive effect on life satisfaction. Finally, it was found that cognitive function was as a mediator in the relationship between exercise participation and life satisfaction of the elderly. Various discussions on the structural relationship between the elderly's participation in exercise, cognitive function, and life satisfaction were presented.

다자간 그룹 통신에서는 일대일 통신과 다르게 그룹에 참여하는 참여자의 수가 많아지고, 각 참여자의 정보량이 많아짐에 따라 참여자들의 정보와 현재 상태 등을 체크하는 멤버쉽 관리 기능을 해 주는 구조가 필요하다. 본 논문에서는 이러한 다자간 통신에서 그룹에 참여하는 참여자들을 관리하는 그룹 관리 프로토콜의 한 부분인 멤버쉽 관리(Membership Management) 기능을 설계 구현하였다. 이러한 MM 기능은 클라이언트／서버 기반으로 동작하며, 서버측에서 모든 클라이언트의 멤버쉽을 관리한다. 설계된 멤버쉽 관리 기능의 알고리즘은 간단하기 때문에 그룹 통신에서 간단하고 효율적인 멤버쉽 관리를 할 수 있으며, 멤버쉽 관리를 서버측에서 함으로서 송신자측의 부담이 줄어든다. 본 논문에서는 멤버쉽 관리를 시험하기 위한 응용으로서 멀티캐스트 전송 프로토콜인 ECTP 배포판에 나온 응용을 사용하여 시험하였다.

Objective : The purpose of this study was to identify the relationships among cognitive function, activities of daily living (ADL), participation and quality of life in community-dwelling elderly. Methods : Cognitive function, ADL, participation and quality of life were assessed in the 144 elderly people residing in the community. We used MMSE-K for measuring cognitive function, K-ADL for ADL, K-ACS for participation, and GQOL for quality of life. Results : Cognitive function was significantly correlated with social activity of participation and quality of life (physical health, psychological health, social relations and economic level). ADL was significantly correlated with participation (instrumental ADL, leisure activity) and all sub-areas of quality of life. Social activity of participation were significantly correlated with all subarea of quality of life except physical health. Among the variables, the most relevant variable was leisure activity. Conclusion : It was related to quality of life in the order of participation, ADL, and cognitive function. Among the sub-areas of participation, leisure activity was the most correlated with quality of life. This study, thus, aimed to provide basic data for successful elderly life by examining the correlation between cognitive function, daily life activity, participation and quality of life in community-dwelling elderly.

The purpose of this study was to analyze the relationship between social participation activities, cognitive function, and depression of middle and old single-person households in consideration of social problems such as aging population and increasing single-person households. For the analysis, path analysis and multi-group analysis were conducted. As a result of the analysis, it was found that social participation activities of middle and old single-person households reduced depression through increased cognitive function, and the positive effects of social participation activities were stronger in groups of dementia. Based on these results, we discussed ways to promote social participation activities, implications for developing programs that can help cognitive function or mental health, and suggested the need for programs or treatment methods to promote social participation rather than isolated treatment in nursing facilities.

The purpose of this study is to analyze the effect of social participation types on cognitive impairment degree(normal, mild, severe cognitive function) by urban and rural difference. The research was performed by multinomial logistic regression with the data of elderly 5,668 over 55 years of age from the sixth wave(2016) and the seventh wave(2018) of the Korean Longitudinal Study of Ageing. Results show that social participation reduces the risk of cognitive impairment on both urban and rural older adults regardless of types, but the types of social participation, which are effective to reduce the risk of cognitive impairment, are different between urban and rural area. According to residential area, types of social participation, which are effective to decline the risk of being mild or severe cognitive impairment and the risk of being severe cognitive impairment relative to mild, are different. These findings suggest that, in order to prevent cognitive impairment and reduce the severity, social participation is strongly recommended and appropriate supports are required. This implies policy and intervention efforts considering the urban and rural difference are needed.

The present study examined whether the relation between relative handgrip strength and cognitive function varied by paid employment status and participation of social activities among Korean older adults. A total of 3,376 Korean adults aged 65 or older were drawn from the 2016 Korean Longitudinal Study of Ageing (KLoSA). Weighted hierarchical regression analyses were conducted to examine moderating effects of paid employment status and social activities on the relation between relative handgrip strength and cognitive function. After adjusting for covariates, results show that relative handgrip strength has a positive association with cognitive function. Both paid employment status and social activities have positive associations with cognitive function and moderate the relationship between relative handgrip strength and cognitive function. These significant moderating effects show that participating in paid employment and social activities buffer against the effect of lower handgrip strength on cognitive function. Findings from the present study highlight the significant role of active aging in older adults'cognitive function. Implications are discussed in a cultural context.

This study examined the relationship between social support, social participation and physical functioning among older adults in community senior centers. The subjects of this study were 194 persons aged 60 years or older who participated in the senior center in K province and D city, from June 16 to June 30, 2016. The collected data were analyzed using descriptive statistics, T-test, one way ANOVA, Pearson correlation analysis, multiple regression analysis, and structural model analysis using IBM SPSS Statistics 23.0 and IBM AMOS 21.0. The result showed that the social support and physical functioning of the elderly in the community were above normal, and social participation was somewhat low. Interestingly, an analysis of the physical functioning between social support, social participation and depression revealed significant correlations. The factors affecting the physical health were 23.4% of the respondents who had a significant influence on social support and leisure activities. In addition, the result of structural model analysis showed that social support had a significant influence on the social participation, depression and physical functioning. Therefore, the results suggests that the development of educational programs and an age-friendly environment should be actively provided to older adults in the community by strengthening the physical function through social support for active ageing.
