The purpose of this study is a exploratory study for understanding the process of the social isolation of the socially isolated elderly through the approach to their life history. The research was analyzed by one of the methods of qualitative research on life history, the conceptual framework of 'Dimensions, turning, and adaptation' of Mandelbaum(1973). According to the results of this study, the socially isolated elderly people were found to be socially isolated by experiencing complex difficulties such as family disconnection, poverty, poor job and health deterioration. Specifically, in the area of life, there was experience of poor relationship with parent, absence of family, poverty of family and unfavorable relationship with surrounding people in life with original family before isolation. They had bad jobs in the labor market, such as hard labor, delivery, business, and chores. In the area of turning point, we experienced family break due to the separation of the original family and the spouse due to various reasons such as financial crisis, parental divorce and death, spouse affair, economic difficulty. In a transitional stage in the life, many reasons such as the financial crisis, the death of parents, the extramarital affair and economic difficulties led to the disconnection from their original family and their spouses. In an adaptive phase, participants accepted the changed life at each turning point in their lives, carrying out their roles, compromising and trying to adapt properly. He said that their current life, which has entered the social safety net system of the people's basic recipients, has led him to live a more stable life and is adapting to personal hobbies and vicarious satisfaction through networks. This result is somewhat different from previous studies in which isolated elderly people were severely exposed to the risk of depression and loneliness. However, we should also consider the characteristics of this study that interviewed elderly people with relatively low isolation. Based on the results of this research, he presented various practical policy implications.

The purpose of study was to investigate the impacts of social isolation, psychological acceptance, and sleep disorder on depression among nursing students. Subjects were 383 nursing students in Gyeonggi-do, and survey was conducted from June to July 2015. The data were analyzed by t-test, ANOVA, Pearson's correlation coefficients, multiple regression analysis. The results showed that depression was different in grade, academic stress, major satisfaction of nursing. Depression was correlated with social isolation (r=.47, p<.001), sleep disorder (r=.43, p<.001), and psychological acceptance (r=-.41, p<.001). Academic stress, major satisfaction of nursing, sleep disorder, social isolation, and psychological acceptance were identified as factors affecting depression. It is necessary to be considered social isolation, psychological acceptance, sleep disorder and other variables in developing convergence program to reduce depression in nursing students.

Social relations and cognitive function in old age are closely related to each other, and social relation is classified into structural characteristics and qualitative characteristics reflecting cognitive and emotional evaluation. The concept of social isolation is the focus of attention in relation to the social relations of old age. Social isolation has a multidimensional theoretical structure that is divided into objective dimension such as social network, type of furniture, social participation, and subjective dimension such as lack of perceived social support and loneliness. There is also a close relationship between cognitive function and interpersonal conflict in old age. In this study, we examined the effect of subjective social isolation, which shows the structural characteristics of social relations, and subjective social isolation and interpersonal conflict on the dementia occurrence by age group in the elderly. The data were analyzed by applying a random effect panel logit model using 1,740 panel data from the first year to the third year of KSHAP. The results of the analysis are summarized as follows. First, the cognitive impairment increased sharply with age. Objective and subjective social isolation were both U-shaped distribution with an inflection point of 80 years old. Second, the main effect on the probability of cognitive impairment was statistically significant with objective and subjective social isolation, but the type of interpersonal conflict did not appear to be significant. Third, the results of two-way interaction effect analysis on the probability of cognitive impairment are as follows. The relationship between subjective social isolation and the probability of occurrence of cognitive impairment was significantly different according to the level of conflict with spouse. In addition, the higher the subjective social isolation, the higher the probability of cognitive impairment in the elderly(over 85) than in the young-old(65~74). In addition, as the level of conflict with spouses increases, the probability of cognitive impairment of the oldest-old(aged 85 or older) is drastically lower than that of the young-old(aged 65~74). Based on the results of this study, policy and practical implications for reducing the cognitive impairment of the elderly age group were suggested, and limitations of the study and suggestions for future research were discussed.

The purpose of this study was to identify the relationship between social-emotional isolation, depression, and smartphone addiction of college students who experienced social distancing caused by COVID-19 and to identify the factors influencing smartphone addiction of college students. Total of 220 students from four universities participated in this study, and data collection was conducted by organizing a questionnaire in a Google form. Data were analyzed using the SPSS/WIN 28.0. There were significantly correlation among smartphone addiction of college students, social-emotional isolation (r=.44, p<.001) and depression (r=.51, p<.001). The factors affecting smartphone addiction of college students were gender (β=.176, p=.001), weekend smartphone usage time 7-9 hours (β=.387, p=.001), 10-12 hours (β=.313, p=.006), 12 hours or more (β=.299, p=<.001), depression (β=.302, p<.001), and social-emotional isolation (β=.210, p=.004). The regression model was statistically significant (F=15.81, p<.001). The explanatory power of the model was 43% (adj R²=.43, p<.001). Therefore, in order to prevent smartphone addiction of college students, it is necessary to develop and utilize a mental health promotion program that can reduce social-emotional isolation and depression.

상수관의 노후화로 인해 상수관망의 안정성 확보와 지속적인 용수공급에 대한 신뢰성을 증대시키는 것이 중요해지고 있다. 용수공급시스템을 구성하는 상수관의 파괴가 빈번하게 발생하며, 관 파괴 시에 수리, 교체를 위해서 관망의 일부분은 차폐가 되어 해당 지역의 용수 수요자는 수리, 교체작업이 끝날 때까지 단수가 불가피하다. 이런 불편함과 손실을 최소화하기 위한 방법을 찾는 것은 상수관망의 유지관리에서 중요한 문제이다. 상수관망의 부분적 격리는 오염물에 의한 상수관망의 오염, 테러로 인한 독극물의 유입 시 물질의 확산 방지, 상수관망을 이루는 각종 구조물의 고장수리 및 유지 보수 작업 등의 상황을 위해 필수적이다. 상수관망의 부분적 격리를 분석하기 위해서는 '고립구역'이라는 개념이 필요하다. 관 파괴시 밸브가 닫히면서 해당 관과 연결된 관들 또한 함께 격리되는 부분을 '고립구역'으로 정의한다. 관이 두 개의 밸브를 양 끝에 가지고 있는 경우와 독립적인 절점 또한 하나의 '고립구역'으로 정의할 수 있다. 본 연구에서는 이러한 '고립구역'을 실제 상수관망에서 탐색해서 정의할 수 있는 알고리즘을 제시하였다. 뿐만아니라 상수관 파괴 시 복구를 위해 파괴된 관을 포함한 고립구역이 차폐될 경우, 세그먼트내의 관들은 수원지로부터의 물공급에 차질이 생길 수 있다. 특정 관들의 고립구역이 수원지로부터 유일한 용수공급경로일 경우 고립구역의 차폐로 인해 해당 관들의 용수공급도 끊어지게 되는데 이러한 영역을 '비의도적 고립구간'이라 한다. 본 연구에서는 이러한 '비의도적 고립구간'을 실제 상수관망에서 탐색하여 정의할 수 있는 알고리즘을 제시하였다.

상수관의 노후화 혹은 공사 중 작업자의 실수, 또는 자연재해 등에 의해 상수관망 내 파손 관이 발생할 경우 파손된 관의 보수 및 교체 작업을 위해서는 파손 관과 인접한 밸브를 차폐하게 된다. 이로 인하여 관망의 일부 지역에 물 공급이 차단되는 단수구역이 발생하게 되며, 단수구역은 밸브를 닫음으로 인해 파손 관과 함께 격리되는 직접고립지역(segment)과 직접고립지역을 차폐함으로써 의도치 않게 수원으로부터 물 공급이 차단되는 간접고립지역(unintended isolation)으로 구분할 수 있다. 간접고립지역은 차폐된 직접고립지역으로 인해 수원으로부터의 유일한 용수공급 노선이 차단되어 발생한다. 관 파손에 의한 단수 피해를 현실적으로 모의하기 위해서는 밸브위치에 따른 단수구역을 정확히 산정할 필요가 있다. 단수구역은 파손관의 위치뿐만 아니라 차단 밸브의 개수 및 위치에 따라 달라진다. 따라서, 관 파손에 의한 단수피해를 최소화하기 위해서는 각 관로의 파손확률과 절점의 중요도를 고려하여, 적절한 밸브의 위치를 선정해야 한다. 본 연구에서는 관 파손에 따른 단수상황을 모의하여 파손 관에 의한 직, 간접 단수구역을 탐색한 후, 단수용량을 파악하고 이를 최소화하기 위한 밸브의 적정 위치를 최적화 알고리즘을 이용하여 결정하는 방안을 제시하였다.

This study was conducted to identify the influence of the discrimination experienced in daily life and social isolation on depression among older adults living in the community. This study was a secondary analysis of the data of 2017 Living Profiles of Older Adults Survey. The participants was a representative sample among the older adults 65 years and older. Data from 10,041 older adults were analyzed for this study. Hierarchical logistic regression analyses were used. When the discrimination experiences was added in model 1, the likelihood of being depressed was 1.95(1.60-2.36) times higher for those who experienced discrimination comparing with those who didn't experienced discrimination. When the social isolation was added in model 2, the likelihood of being depressed was 1.89(1.55-2.30) times higher in those who experienced discrimination. In addition, as the number of close friends, neighbors, and acquaintances decreased by one, the likelihood of being depressed increased by 1.14 times. Those who were isolated from family, friends, neighbors and acquaintances were 3.90 times more likely to be depressed. Therefore, social efforts are needed to reduce the experience of discrimination. Maintaining a social network or creating a new network will contribute to lowering the level of depression in older adults who have experienced discrimination.
