인터넷 기술의 발달로 인해 온라인상에서도 사회연결망이 나타나고 있다. 블로그 월드는 대표적인 온라인 사회연결망이다. 블로그 월드의 구성원인 블로거는 정보를 생성할 수도 있고, 정보를 얻기 위하여 다른 블로거와 명시적 관계를 맺을 수도 있으며, 이러한 관계를 통해 온라인 사회연결망인 블로그연결망을 구성한다. 사회 연결망 이론에서는 사회 연결망에서 정보의 파급이 구성원간의 관계를 통하여 이루어진다고 한다. 그러나 블로그 연결망과 실제 블로그 월드에서 발생한 정보 파급 이력을 비교 관찰해 보면, 사회연결망 이론과 달리 관계가 존재하지 않는 구성원 사이에서 정보 파급이 일어난다. 또한, 정보의 파급이 폭발적으로 일어나는 현상도 존재한다. 본 논문에서는 이러한 두 현상이 서로 연관이 있음을 밝히고, 이러한 현상을 일으키는 원인을 규명하는 분석방법을 제안한다. 제안하는 분석방법은 다음과 같다. 우선, 관계가 존재하지 않는 구성원 간에 정보 파급 현상을 유발할 수 있는 후보원인들을 모두 도출한다. 다음으로, 폭발적인 정보 파급 현상을 보이는 정보의 집단을 데이터 마이닝의 클러스터링 기술을 이용하여 도출한다. 도출된 정보의 집단과 후보 원인간의 상관관계를 데이터 마이닝의 특성분석 방법을 이용하여 구한다. 블로그 월드는 구성원과 그 사이의 관계, 정보 파급 이력에 대한 데이터를 모두 저장하고 있다. 본 논문은 실제 블로그 월드의 데이터를 이용하여 블로그 월드에서 정보의 폭발적 파급을 유발하는 원인들을 규명하고 그 원인들이 가지는 특징을 설명하였다.

이 연구는 사회관계망의 형태와 구성원에 관한 정보를 분석하여 모바일로 서비스하는 것에 관한 연구이다. 사람들은 얽히고 설킨 다양한 인간 관계를 갖고 있다. 인간 관계를 유지하기 위해 여러 채널을 통해 커뮤니케이션을 하게 된다. 실생활에서 갖게 되는 인간 관계의 형태와 가장 비슷한 형태의 커뮤니케이션 채널은 휴대전화이다. 사회관계망 이론의 관점에서 보면 휴대전화의 사용은 기존의 인맥에서 친밀도가 적은 사람에게는 영향이 크지 않지만 친밀도가 높은 사람에게는 더욱 친밀하게 만드는 영향을 준다. 이 연구에서는 휴대전화의 통화상대, 통화시간, 통화량 등의 정보가 나타나있는 통화기록에 기반하여 일정기간 동안 통화한 상대들을 추출하였다. 통화기록의 정보를 사회 관계망 분석 도구인 UCINET으로 분석한 결과 휴대전화를 매개로 한 사회관계망의 형태가 자아 중심적 관계망과 같은 형태를 지니고 있다는 사실을 도출해냈다. 그리고 자아 중심적 관계망의 분석 기법을 이용하여 관계망의 중심에 있는 자아와 통화상대와의 관계를 분석하였다. 또한 통화상대들의 휴대전화 통화기록을 통해 서로 관계가 있는지에 대해 알아보았다. 그 결과 자아의 인맥 네트워크 안에 있는 사람들을 그룹화하고 그들의 나이, 성별, 직업에 의해 어떠한 특징을 갖는 그룹인지 분석하였다. 이러한 연구는 휴대전화를 통해 자신의 인간 관계 형태를 파악하여 관계를 관리하고 유지할 수 있는 새로운 모바일 서비스 개발을 위해 활용될 수 있을 것이다.

In Korea, since the systematic efforts to help unmarried mothers are rather limited, the unmarried mother's social relationship is expected to play a critical role in the adjustment of unmarried mothers after the birth of a baby. The purpose of this study is to identify the effect of social relationship on unmarried mother's self-esteem. Especially, this study focused a negative aspect of social relationship, social conflict, which has been ignored by the previous researches. For this study, survey method was employed. The respondents of the questionnaire were 205 unmarried mothers staying at six out of eight institutions for unmarried mothers available in Korea. The multiple regression and other descriptive statistical methods were conducted and the results of analysis are as follows. First, the higher the level of perceived social support was, the higher the level of self-esteem of unmarried mothers was. Second, the higher the level of perceived social conflict was, the lower the level of self-esteem of unmarried mothers was. Third, even though the level of perceived social conflict was much lower than the perceived social support, the effect of social conflict on unmarried mothers' self-esteem was as powerful as the social support. This means that the effect of social conflict also can be very important. These findings suggest a new direction for intervention for unmarried mothers. Until now, the major target of intervention in social relationship was to strengthen existing social support or establish new social support system. Now, in addition to augmenting social support, we should pay attention to removal of social conflict, since it has significantly powerful effect on the adjustment of unmarried mothers.

This paper is a theoretical attempt to analyze and understand Yeonjulmang and Yeongyeolmang, which are terms for social networks with negative and positive connotation respectively in Korean Sociology. To do that, we analyze a social network where unilateral help are reciprocated. A social network in this context is a network where the past behaviors of its members are transmitted. With the information how the members behaved before, a social norm can emerge in the network, which facilitate the indirect reciprocation of unilateral help. In this norm, an agent's helping now will be rewarded by his being helped in the future. Since the reward happens in the future, this norm may not be sustained even if it is efficient. To sustain the reciprocation of the help, a norm can evolve to punish the violation of the norm more severely. If the punishment becomes too severe, the reciprocation of the help can be sustained even if it is not efficient any more in that the cost of help exceeds the benefit. If we allow the exit of the network, members have incentive to do it as belonging to the network is not beneficial any more. Then the social network may collapse. To avoid the collapse of the network, the exclusive norm, which exclude even mutually beneficial relationship with outsiders, may emerge. This can explain the emergence of Yeonjulmang, or a closed network, which is inefficient in double senses; 1) it may sustain inefficient reciprocation of help, and 2) the mutually beneficial relationship is excluded between an insider and an outsider of the network.

The present study investigated the mediating effects of parents' social networks on the relationship between parents' socioeconomic status and parent involvement. Parent involvement in the current study was composed of home-based and school-based involvement. Home-based involvement includes providing learning environment at home, guiding child's study habits, and providing educational and financial support. School-based involvement includes supporting child's school-related activities, participating at parent meetings and volunteering, and home-school communication. The subjects were 132 single mothers and 164 mothers from two-parent families, whose children are fifth and sixth graders in Seoul and Incheon. Structural Equational Modeling was used for the analysis by adopting SPSS 18.0 and AMOS 18.0. The results showed that single mothers and mothers from two-parent families differ in their structural models. For mothers from two-parent families, socioeconomic status was directly related to home-based and school-based involvement. In contrast, single mother's socioeconomic status only influenced home-based and school-based involvement indirectly through the functional aspects of mother's social networks. The results suggest that parent counseling and parent education programs might be more effective if they encouraged single mothers to exchange resources through their social networks in order to promote parent involvement in elementary schools.

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.
