The objective of the study was to analyze difference in cognitive function according to social isolation level in elderly Korean. The author classified the social isolation into the structural isolation and contact isolation. Structural isolation corresponded to the no spouse or no children and the contact isolation corresponded to the absence of contact with children, friends or social association. Author conducted multivariate regression analysis with the elderly people aged 65 years or older from the 5th wave of the Korean Longitudinal Study of Ageing data. Number of sample was 3,971. It was confirmed that the level of cognitive function was lower according to level of social isolation. It was also confirmed that friends/neighborhood isolation, and social activity isolation showed significant relationships with cognitive functions. Based on the results, author suggested that to protect the elderly from negative effects of social isolation, we needed the policy to promote elderly's the participation in social activity. The study to analyze the factors related to social isolation was also needed.

Along with the well-established evidence on the negative effect of social isolation on physical and mental health, increasing attention has been paid to multi-dimensional nature of social isolation. One line of study on social isolation has discussed different pathways between objective and subjective social isolation and health. Another stream of the research focused on the possibly non-linear association between social isolation and health by age cohort groups. Drawing from the two lines of research, this study aimed at empirically examine to what extent objective and subjective social isolation are associated with physical and mental health independently and how the associations vary by three age cohorts(i.e. the middle-aged, the young old, the old-old). Data came from the first wave of Korean Social Life, Health and Aging Project (KSHAP) (N= 814). Findings showed 1) objective subjective isolation were significantly related with worse physical and mental health, interestingly, subjective social isolation was associated with mental health only, 2) pattern of association between social isolation and physical health varied by age cohorts. Specifically, compared to the middle-aged, the young old with higher objective social isolation exhibited lower level of physical health, while the old-old with higher subjective social isolation were likely to experience lower physical health. Based on the findings, we discussed implications and suggestions for future research and relevant policy/program development for ameliorating objective and subjective social isolation.

Along with the well-established evidence on the negative effect of social isolation on physical mental health and mortality, increasing attention has been paid to multi-dimensional nature of social isolation. In this study, the main effect and interaction effect of objective and subjective social isolation on heterogeneous age cohort related to the onset of dementia, which is becoming a social problem due to rapid aging of health issues, was examined through binary logistic regression analysis. Data came from the first wave of Korean Social Life, Health and Aging Project (KSHAP) (N= 814). Findings showed 1) in the young-old, objective isolation was a significant on the incidence of dementia, 2) in the old-old, subjective isolation increased the risk of dementia. In summary, the relative influence of objective and subjective social isolation related to the incidence of dementia varies depending on the young-old and old-old. On the other hand, the interaction effect of objective and subjective social isolation on dementia was not significant in both the young-old and old-old. Based on the findings, we discussed implications and suggestions for future research and relevant policy and program development(dementia-friendly communities) for ameliorating objective and subjective social isolation.

This study aimed to identify the mediating effect of social support on the relationship between social isolation and depression in nurses. This study was conducted with 135 registered nurses in three COVID-19 specialized hospitals. Data were analyzed with IBM SPSS Statistics 25.0 and using descriptive statistics, Pearson correlation coefficient, and mediation analysis. The mediating effect was analyzed using PROCESS macro for SPSS 4.0 program with bootstrapping method. Social isolation directly influenced social support (𝛽=-.62, p<.001) and depression (𝛽=.49, p<.001). Social support directly influenced depression (𝛽=-.19, p=.028). Social support has a mediating effect between social isolation and depression (indirect effect=.12, 95% CI=0.02~0.29). To managed depression, intervention are needed to reduce social isolation. Therefore, it is necessary to develop strategies that enhance social support to relieve depression in nurses perceived social isolation.

상수관망시스템은 정수장으로부터 각 수요처에 음용수를 공급하기 위한 사회기반시설물이며, 광범위한 지역에 걸쳐 주로 지하에 시설물이 매설되어 있다. 상수관망시스템을 설계하고 운영함에 있어 노후화로 인한 유수율 저하, 갑작스런 수요량의 증가, 관로 파손 등 비정상상황에의 용수공급을 항상 대비하여야 하며, 이를 통한 지속적인 관리와 개량이 필요하다. 상수관망시스템에서 발생할 수 있는 다양한 비정상상황들 중 상수관망시스템 내 관로가 파손될 경우, 파손 관로의 보수 혹은 교체를 위해서는 해당 관로의 용수흐름을 일시적으로 차단할 필요가 있다. 이 과정에서 파손관로와 인접한 밸브를 차폐하게 되며, 이로 인해 용수공급이 중단되는 단수구역이 발생하게 된다. 단수구역은 파손 관로를 차폐함으로써 파손 관로와 함께 용수공급이 차단되는 직접고립지역과 직접고립지역으로 인해 의도치 않게 수원으로부터 물 공급이 차단되는 간접고립지역으로 구분할 수 있다. 따라서, 관 파손에 의한 단수용량을 정확히 산정하기 위해서는 시스템 내 설치된 밸브의 개수와 위치에 따른 직, 간접고립지역(단수구역)을 정확하게 산정할 필요가 있다. Jun and Loganathan(2007)은 단수구역을 직접고립지역과 간접고립지역으로 구분하여 정의하고 각각을 탐색하는 알고리즘을 제시한 바 있다. 본 연구에서는 기존 연구에서 제시한 간접고립지역 탐색 방법의 문제점을 파악하고, 이를 개선한 새로운 알고리즘을 제안 및 검증하였다. 또한, 개선된 알고리즘을 이용하여 상수관망시스템 내 최적 밸브위치를 결정하기 위해 단수용량과 밸브설치비용을 동시에 최소화하는 다목적 최적화 모형을 개발하였으며, 예시 관망을 이용하여 모의를 수행하고 결과를 분석하였다.

This study explored the potential associations among older adults' online community uses, socialization, and social isolation. Results from the hierarchical regression analysis indicated that the quality and size of personal networks composed of online community members positively influences older adults' socialization and reduces social isolation. However, the frequency of meeting with online community members in offline settings was not significantly associated with socialization. Moreover, the amount of time using online communities indirectly and significantly affected social isolation, mediated by socialization. Results from this study address the positive roles of online community uses in overcoming psychological difficulties among elderly people.

This study estimates future AADT using historical AADT and socio-economic factors in isolated area. Multiple linear regression method by socio-economic factors are lower MAPE and higher R-square than using historical AADT. Analysis of socio-economic factors influence AADT in isolated typical areas, varied socio-economic factors influence on AADT. In isolated coastal areas, oil price influence on AADT. AADT forecasting model in isolated area is excellent when analysising $R^2$ and MAPE. It is assume that estimation of AADT in isolated area using multiple linear regression is accurate because of a little passed traffic volume and traffic volume fluctuation.
