The purpose of this study was to investigate the relationship between health-related physical fitness factors and cognitive function and isolation on 308 elderly over 65 years old in Seoul and Gyeonggi do. The measuring instrument were as follows demographic characteristics(age, education level, drink, spouse, participation on in exercise) and health-related physical fitness(grip strength, leg strength, flexibility, balance), cognitive function (MMSE-K, digit span test) and emotional/social aspects of loneliness and isolation was measured. As a results, first, depending on the degree of demographic characteristics of elderly had significant difference. Second, health-related physical fitness and cognitive function are positive correlated, negative correlation between cognitive function and isolation. Third, health-related physical fitness of the elderly had a significant effect on cognitive function. Fourth, health-related fitness of the elderly had a significant effect on isolation. Fifth, the cognitive function of the elderly had a significant effect on isolation. In conclusion, this study will provide basic data for future aged man welfare studies and contribute to extended studies.

The purpose of this study was to explore the effects of sportsclub on social integration through the sportsclub participation and social integration index. To achieve this goal, 26 countries among OECD members were selected. Life satisfaction, mutual trust, social isolation, happiness index, social conflict index were selected for correlation analysis. Main findings were as follows. First. Norway, Denmark, Germany, Sweden had higher sportsclub participation, on the contrary, Korea, Poland, Hungary, Greece, USA had lower sportsclub participation. Second, sportsclub participation had significant correlation with life satisfaction, mutual trust, social isolation, happiness index, and social conflict index. Specifically, sportsclub participation had positive relationship with life satisfaction, mutual trust, happiness index and negative relationship with social isolation, social conflict index.

The purpose of this study was to investigate social networks, loneliness, and sleep quality related to health-related quality of life in older adults living alone. Data were collected from 111 community-dwelling elderly. The data were analyzed using descriptive statistics, independent t-test, one-way ANOVA, Pearson's correlation coefficients, and multiple linear regressions with IBM SPSS 26.0 program. In multiple regression analysis, physical component summary (PCS) was predicted by the level of education (β=.20, p=.020), social networks (β=.31, p=.012), and sleep quality (β=-.23, p=.011). The model including these variables accounted for 25.7% of the variance in the PCS. Mental component summary (MCS) was predicted by loneliness (β=-.37, p=.004). Loneliness accounted for 31.7% of the variance in the MCS. In order to enhance the health-related quality of life of the older adults living alone, the intervention program to resolve social isolation should be provided for them.

If pipes are damaged in a water distribution network (WDN), adjacent valves are closed to isolate the pipes for repair. Due to the closed valves, parts of WDN are isolated from water supply sources. The isolated area is divided into Intended Isolation Area (IIA) and Unintended Isolation Area (UIA). The IIA occurs by intention to isolate the damaged pipe, while UIA is unintentionally disconnected from the sources due to IIA. Thus, the extension of isolated area and suspended flows are mainly affected by number and location of installed valves in WDN. In this study, optimization models were developed to determine optimal valve locations in WDN. In a single-objective model, total water supply suspension is minimized, while a multi-objective model intends to simultaneously minimize the suspended flow and valve installation cost. Optimal valve placement results obtained from both models were compared and analyzed using a sample application network.

본 연구는 최근 중장년층 남성의 고독사 문제를 다루며, 남성 갱년기와 고독사, 정신 건강 문제의 연관성을 통계분석으로 확인한다. 연구 결과에 따르면, 사회적 고립도와 우울증, 불안장애는 고독사 위험 정도와 밀접한 관련이 있음을 알 수 있다. 이를 바탕으로 현재까지 존재하지 않았던 남성 갱년기 프로그램 도입을 제안하고자 한다. 프로그램이 활성화될 경우 중장년층의 고독사와 사회적 고립도를 완화시키며, 노후 생활의 질을 향상시킬 수 있을 것으로 기대한다.

This study examines the problem of efficient scheduling of waste collection in isolated regions like islands when the waste accumulated amount surpasses the standard ceiling by effectively tracking the accumulating trends based on the optimum checking model of Keller (1974). To grasp whether the waste accumulated amount in isolated regions exceeds the standard ceiling, the relevant authorities can tightly check during a set period, but this entails higher monitoring costs. On the other hand, if the accumulated waste over the ceiling is not immediately checked and collected, and continues for a set period of time, innovative efforts for waste management may be highly demanded. As such, the tradeoffs are considered to draw the optimal checking schedule. This study shows that the authorities get to check less frequently the waste accumulation trends if the monitoring costs increase or when the failure rate of waste management systems drops. On the other hand, they get to check more frequently if the accumulated waste amount in isolated regions exceeds the standard ceiling and welfare loss grows as a result. It also shows that frequent checking is the optimal choice if the social marginal benefits enjoyed from innovative efforts made to keep accumulated waste below the standard ceiling, are not significant.

적절한 영양섭취는 노인에서 나타날 수 있는 각종 생활습관질환의 예방과 치료에 도움을 줄 뿐 만 아니라, 신체 기능을 향상시켜 삶의 질 향상에 중요한 역할을 한다. 노인계층은 노화에 수반되는 각종 생리기능의 저하, 사회심리적 고립, 유병상태 및 투약, 활동량 저하에 따라 식생활이 불량해지며, 이는 곧 영양상태 불량을 초래하여 건강을 더욱 악화시킨다. 우리나라는 현재 노인 인구의 급격한 증가에 따라 지역사회 노인 대상의 각종 보건영양서비스 필요성이 대두되고 있다.(중략)
