This research investigated how the participation of various social activities affects cognitive function in middle-aged and elderly population. To examine the relation between the participation of various social activities and cognitive function, we used data from the Korean Longitudinal Study of Ageing. Social activities were classified into four types as religious ritual, leisure, public association and ascriptive association activities, and MMSE-K score was used to measure cognitive function. Results from multiple regression analyses after adjusting for socio-economic status and health status show that the participation in religious and leisure activities have positive effects on cognitive function in middle-aged and elderly population. Participation in leisure activities in middle-aged male group helps preserve cognitive function, and leisure activity and ritual activity are significantly related to cognitive function in middle-aged female group. Meanwhile the participation in religious and leisure activities have positive effects on cognitive function in elderly male and female group. Based on these findings, we suggest that various programs to support the participation of elderly population in social activities should be developed for healthy life for the elderly.

우리나라 항만배후단지는 수출입 화주의 글로벌 SCM 지원 및 효율적 물류활동을 지원하고, 항만의 고부가가치화를 실현하기 위해 개발 및 운영되고 있다. 따라서 물류센터를 운영하는 항만배후단지 입주기업들은 다양한 부가가치 물류활동을 수행할 것으로 기대되었으나, 여전히 단순 보관기능 위주의 활동에 치중되어 있다는 비판을 받고 있다. 본 연구는 국내 항만배후단지 입주기업의 부가가치 물류활동 실태를 설문조사를 통해 분석하였다. 응답 입주기업의 44%가 단순 하역, 운송, 보관 기능만 수행하는 것으로 조사되었고, 5개 이상 부가가치 물류활동을 수행하는 기업은 전체의 11%로 낮은 수준으로 나타났다. 또한 포장, 분류, 라벨링 등 비교적 저수준의 부가가가치 물류활동이 전체 부가가치 물류활동의 약 60%로 나타났고, 2017년 기준 부가가치 환적화물의 처리 비중은 2.6%로 상당히 낮은 결과를 나타냈다. 항만배후단지 입주기업의 부가가치 물류활동 수준을 제고하고, 부가가치 환적화물 유치 강화 등을 위한 경쟁력 강화방안 마련이 요구된다.

Aim: This study investigated the association between leisure activities and cognitive impairment in Korean community-dwelling older adults. Methods: Among participants of the 2017 National Survey of Older Koreans, 10,055 (male=4,277, female=5,778) were included in this cross-sectional study. To better identify the association between late-life cognition and leisure activities, individual leisure activities were categorized into 3 types including productive, consumptive, and unclassified activities. Multivariate logistic regression analysis was performed to assess the association between participation in leisure activities and cognitive impairment when controlling for possible covariates evidenced by previous studies. Results: Male participants were more likely to be cognitively impaired than female ones with significant differences in all the covariates. After controlling for confounding variables, involvement in productive leisure activities was found to be associated with cognitive function in both male and female groups, along with age, educational level, depressive symptoms, subjective hearing problems, and occupational status. Conclusion: Involvement in productive leisure activities might be associated with decreased risk of cognitive impairment in later life. Appropriate strategies to encourage older adults to participate in productive leisure activities should be established to help them maintain their cognitive function.

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.

Objectives. The purpose of this investigation was to study the correlation between cognitive impairment and activities of daily living(ADL) In the elderly of rural area. Methods. The study population consisted of 210 elderly people aged 65 years and older, living in a district of Kyongju City. The cognitive impairment was measured with the Korean version of mini-mental state examination(MMSE-K) and newly constructed the Korean version of mini-mental state examination (K-MMSE). Bristol activities of dally living scale developed specifically to be used with people with dementia was used to measure ADL Results. The mean scores of both MMSE-K and K-MMSE were significantly different by sex groups and by .age groups, respectively(p<0.05). The mean scores of ADL were significantly different by age groups(p<0.01) not by sex groups. Among the 4 components of ADL(instrumental activities of daily living(IADL), self care, orientation, and mobility), the mean score of the orientation was significantly higher in men(p<0.01); and IADL, orientation and mobility components were significantly different by age groups(p<0.01). ADL correlated well with MMSE-K (r=0.54) and K-MMSE(r=0.52) and showed higher correlation in female (r=0.73, 0.71) than male(r=0.27, 0.29). IADL and orientation showed significant correlation with MMSE-K(r=0.52, 0.62) and K-MMSE(r=0.50, 0.63), respectively(p<0.01). Conclusions. In developing and establishing a care model for people with dementia in the community, both cognitive impairment and the activities of daily living(ADL) need to be considered.
