The purpose of this study is to develop a scale for the social network of college students in Korea. The social network scale for college students in this paper was developed through 1) literature review and item development 2) focus-group meeting 3) depth-interview with college students 4) pilot-studies and 5) study. The scale of 23 items has been constructed with three features : The first is 'relational feature' with 2 items; the second 'structural feature' with 7 items; and the third 'functional feature' with 14 items. The functional feature in this social network scale has consisted of emotional, economic, spiritual, and socio-relational aspects and has been revealed to the validity and the reliability of Cronbach's ${\alpha}$ 0.716. This study would contribute for college students to solve the many problems in their own lives through the social networks.

The objective of this study is to examine the association of social networks and medical care utilization of elderly living alone depending on self-rated health status, and also to measure the moderating effects of welfare services for elderly. To this purpose, the data which was collected from the 2014 National Survey on Elderly in Korea was analyzed by Chi-square test and Poisson regression. According to the results, social networks and elderly welfare services affected to medical care utilization of elderly living alone, only who aware of their self-rated health status as bad. With this group, the frequency of contact with family and participation in lifelong education had a significant effect on increasing medical care utilization. In contrast, the frequency of contact with neighbors and the participation in elderly employment program were significant to reduce the utilization of medical care. Furthermore, the moderating effects of elderly welfare services were also measured that formal social gathering has an effect of increasing the medical care utilization of elderly living alone by expansion of their social networks. Based on these results, this study consequently has an implication for suggesting expansion of elderly welfare services, which might be an alternative to social networks of elderly living alone, and also for seeking the direction of political intervention that helps health promotion and disease prevention through the research of medical care utilization.

This study is a descriptive correlation study investigating the effects of stress disorder symptoms, resilience, and social network on post-traumatic growth in traffic accident patients. The participants were 158 traffic accident cases enrolled from five 100-bed hospitals situated in city C. Data were collected from July 1 to August 31, 2018, and analyzed by t-test, ANOVA, Pearson's correlation coefficients, and multiple regression using SPSS / Win23. The explanatory power of post-traumatic growth was determined to be 36.9%, and the factors affecting post-traumatic growth were social network and post-traumatic stress disorder. In addition, social networks completely established the relationship between resilience and post-traumatic growth. Our results confirmed that a wider social network and increased symptoms of post-traumatic stress disorder of the traffic accident patient are associated with higher post-traumatic growth. Therefore, it is necessary to explore approaches that improve the social networks and resilience to help post-traumatic growth of traffic accident patients. Additional research is required through repetitive and long-term observation of the accident victims.

This study examines 2014 National Survey on Older Koreans (10,279 persons aged 65 or above) to understand social networks among older Koreans. In order to classify the types of social relationships, the latent profile analysis is conducted based on such structural aspects of social networks as network size, frequencies of contact, and closeness. The results show that older Koreans can be categorized into 5 distinct social network types: disengaged (11.6%), ritual-family-focused (17.7%), close-family-focused (23.6%), close-restricted (28,4%), and diverse (18.8%). Characteristics by each social network type are compared and multinominal logistic regression analyses are applied to figure out the influencing factors of social network type. Older persons with disengaged social network ties tend to be overwhelmingly female, living alone, old-old, and of low socioeconomic status. On the other hand, older persons with diverse social network ties tend to be young-old and had highly-ranked jobs in their mid-life. Spouse/children are the focal point of social relationships in both ritual-family-focused and close-restricted social network. However, the proportion of men is higher in the close-family-focused type than in the ritual-family-focused. Older Koreans with close-restricted social network ties tend to be female, uneducated, and have engaged in agricultural and allied activities. This study discusses the implications of its findings and how research in this area should develop in the future.

Recently, the necessities of gathering, producing, and sharing criminal information are critically important as intelligence functions of police agencies to improving public safety and national security. However, the inadequacies and barriers within which police agencies have in regard to intelligence functions impede criminal information gathering, intelligence producing within their agency, and intelligence sharing with other agencies. In this study, we analyzed informal networks constructed from a survey dataset of information and intelligence sharing among officers in police agencies. The results revealed the different structural properties of intelligence networks between police agencies. We did find that officers with high indegree and outdegree in a network played critical role on the dynamics and degree of intelligence gathering and assessment responsibilities. Finally, we could find evidence that the potential role of intermediary triggered relational dynamics for developing and sharing critical information among all police agencies.

In traditional social network analysis, the betweenness centrality measure has been heavily used to identify the relative importance of nodes in terms of message delivery. Since the time complexity to calculate the betweenness centrality is very high, however, it is difficult to get it of each node in large-scale social network where there are so many nodes and edges. In this paper, we define a new type of network, called the expanded ego network, which is built only with each node's local information, i.e., neighbor information of the node's neighbor nodes, and also define a new measure, called the expended ego betweenness centrality. Through the intensive experiment with Barab$\acute{a}$si-Albert network model to generate the scale-free networks which most social networks have as their embedded feature, we also show that the nodes' importance rank based on the expanded ego betweenness centrality has high similarity with that based on the traditional betweenness centrality.

The purpose of this study was to identify the types of social networks of urban housewives according to different network composition patterns and to analyze the structural and functional characteristics of identified types. The data used in this study were collected from 589 full-time housewives residing in Taejeon city. The major findings are as follows: 1) The social networks of housewives in urban nuclear families were classified into eight types: the kin network, the non-kin network, the kin-centered network, the friend-centered network, the neighbor-centered network, the associate-centered network, the parallel network, and the decentralized network. 2) The structual characteristics (size, density, homogeneity, duration, proximity, frequency, closeness, direction) varied according to the type. The kin network type and the non-kin network type showed extreme degrees in network characteristics. The parallel network type and the decentralized network type showed an average level of network characteristics. The kin-, friend-, neighbor-, and the associate-centered types showed network characteristics of an intermediate level between the single-category types and the decentralized type. 3) The average levels of function of social network types were different in only two(service support, interference) of the six function areas(emotional support, service support, material support, information support, social companionship support, interference). The average level of service support by the non-kin network type was higher than other types. The average level of interference by the kin-centered network type was higher than other types, and that of the neighbor-centered network type was lower than other types. On the other hand, the total amount of function performance of social network types was different in all function areas. The total amount of social support given by the decentralized network type was greater than the other types. The total amount of interference given by the non-kin network type was smaller than the other types.

The purpose of this study is to analyze the cause-and-effect relationships among positive verbal expressions from family members, social network, and disability identity as the determinant factors of intention to work. To achieve the goal, 453 persons with disabilities and with experiences of using facilities for the disabled were studied, who were recruited for the national survey of domestic violence in 2010. For the research subjects, the cause-and-effect relationships among the major factors were examined by using a structural equation model. According to the results, disability identity and intent to work tended to be higher as they had experienced more of positive verbal expressions from their families. Moreover, a more participation in social activities increased disability identity, but not intent to work. Lastly, disability identity was found to be a determinant of intent to work. Based on the results, we provide suggestions to achieve social inclusion of people with disabilities by raising the intent to work.
