This study was designed to evaluate the social support network of schizophrenic patients. 64 schizophrenic patients being treated as out-door patient were compared with 30 neurotic control patients. Schizophrenics were divided into positive, subpositive, subnegative and negative subgroups by present symptom and social network of both schizophrenics and control group were evaluated. The results are as follows: 1) Social network of schizophrenics was smaller than that of control group. Size of social network of schizophrenics was 10.6 and that of control group was 23.5. 2) In both kin and nonkin, social network of schizophrenics was smaller than that of control group. Of the kin, schizophrenics were more supported by wife or husband, father, and mother, but were less supported by brother, son and other relatives. 3) There was no difference in the kin or nonkin or total supporters between the four subgroups of schizophrenics. But, subgroup of schizophrenics which was divided as having negative symptom had smaller network than control group in active formal and informal supporters. 4) When divided into 4 support areas, schizophrenics was remarkably less supported in emotional, instrumental and appraisal support area than control group, but there was no difference in the informational support areas. 5) Compared with control group, schizophrenics more often mentioned parent and ten often mentioned nonkin supporter as the one that is most important to him. 6) Schizophrenics had smaller cluster and less leisure activity than control group. Subgroup of schizophrenics who was divided as having negative symptom had less frequency of leisure activity than other subgroups.

Objectives: The purpose of this study is to analyze the peer group factor related to adolescent smoking in the social structure(network) of adolescent groups, by applying the theory of social network. Methods: The data was collected from boy students of one high school located in Gun-Po city of Kyonggi Province. The total number of the sample was 605(223 first grade, 198 second grade, 184 third grade). The survey using the questionnaire was carried out in April 2005. Social position is finally classified as clique member, liaison, isolate group by using the NetMiner II 2.5 version. Results: The current smoking rate was 15.0%, and the life-time smoking rate was 34.9%. The smoking rate increased significantly, as the grade went up. And it was significantly high among the group having smoking friends. The logistic regression analysis showed that the odds ratio of the smoking friends group was about 4 times higher than the no smoking friends group in experience of smoking. But the smoking rate was higher significantly in the isolate group within the network composed of 2. person's social-link. The odds ratio of the isolate group was about 4.5 times higher than the clique member. However, this pattern was not found in the network composed of 3 person's social-link. Therefore, the hypothesis that clique member would have a correlation with smoking was rejected. In reality, the isolate group had a tendency of smoking more frequently. Conclusions: The result of this study suggests that the role of the peer group in smoking is to be considered in the prevention program. More attentions should be paid for the isolate group.

스마트폰과 웨어러블 기기의 발달로 다양한 라이프로깅 서비스와 클라우드 서비스가 제공되고 있다. 소셜 네트워크 서비스는 인터넷상에서 개인의 일상을 공유해 친구들에게 근황을 알리고 새로운 인간관계를 형성하도록 한다. 라이프로깅 관련 연구들이 활발하게 이뤄지고 있지만 소셜 네트워크 서비스 시대의 라이프로깅은 단순한 기억의 확장을 넘어 사회적 관계를 제시해야 한다. 또한 사회적 이슈인 개인정보 보호를 위해 익명성이 보장되어야 한다. 본 연구는 일상생활에서 얻어지는 라이프로깅 데이터를 이용해 소셜 네트워크 그룹을 생성하는 시스템을 제안한다. 소셜 네트워크 그룹은 비슷한 감성 성향의 사람들을 범주화함으로써 사회적 관계를 제공한다. 이때, 익명성 보장을 위해 타인을 식별할 수 없도록 한다. 소셜 그룹의 대표 감성과 비슷한 소셜 그룹들을 범주화해서 확장된 소셜 네트워크 그룹을 만들 수 있다. 소셜 그룹간의 네트워크로 확장되면 대표 감성과 행동 양식을 분석해 대중의 패턴과 트렌드를 추론할 수 있는 기초데이터를 제공할 수 있다.

최근 급성장하고 있는 소셜 네트워크 서비스는 인적 네트워크를 반영한 온라인 서비스로서 선거 유세, 기업 홍보 마케팅, 교육적 정보 공유, 의학적 지식 및 의견 교환 등 다양한 목적으로 사용되고 있다. 이 서비스는 공동의 관심사를 가진 사람들이 모여 자유롭게 정보와 의견을 교환하면서 친분관계를 형성하도록 하고, 자신의 프로파일과 친분관계에 있는 사람들을 공개함으로써 다른 사람의 인맥을 활용하여 자신의 관계를 확장시켜 나갈 수 있도록 한다. 그러나 정보의 개방과 공유를 기반으로 하는 소셜 네트워크 서비스는 프라이버시 침해나 피싱과 같은 많은 보안상의 문제를 야기 시킨다. 본 논문에서는 키링을 이용하여 소셜 네트워크에서 소규모 그룹의 통신을 보호하기 위한 키 관리 기법 및 프로토콜을 제시하였다.

This study attempted to identify the type of social network interventions and barriers to implement them. Few empirical studies have been conducted concerning social network interventions as professional activities. Although social support and social network interventions have been noted as important practice concepts, the existing studies ten us little about how social workers perceive and experience social network interventions. This study used seven types of social network interventions identified in the previous studies. And based on "obstacles to social network interventions scale" developed by Biegel, Tracy & Song (1995), a twenty-two item scale was developed by the authors. The results from this study show that social workers little implement social network interventions such as community empowerment, family caregiver enhancement, and support group, and that they perceive organization characteristics and profession-oriented culture as important obstacles to implement social network interventions. The findings from this study suggest various strategies to address these barriers.

소셜 네트워크 연구는 단일노드와 링크에 초점이 맞추어져 있다. 하지만, 소셜 네트워크의 복잡성을 고려할 때, 특정조건을 만족하는 여러 노드에 의한 종합적인 영향을 분석하는 것이 필요하고 생각한다. 하지만, 서브 네트워크 외에는 연구가 진행되고 있지 않다. 본 논문은 여러 노드에 의한 영향 분석에 중점을 두고 있다. 이를 위하여 특정 조건을 만족하는 복수개의 노드로 구성된 그룹노드 용어를 정의한다. 그리고 그룹노드를 적용하여 소셜 네트워크를 새롭게 구성하는 방법을 제시한다. 그리고 특정 조건에 맞는 그룹노드를 구성하는 프로그램을 유전자 알고리즘을 활용하여 제작하고, 결과를 제시하였다. 본 연구가 그룹노드를 기반으로 하는 소셜 네트워크 분석의 시발점이 되기를 바란다.

This study examined structured social network types and their relationship to quality on life satisfaction of older adults. Respondents were 418 adults aged 60 or older living alone or as couples. The data was analyzed using K-means cluster analysis. Four networks types were identified: diverse, friend-neighbor focused, family focused, and restricted. Life satisfaction was highest for individuals in the diverse network group and lowest for individuals in the restricted network group. Stepwise multiple regression analysis indicated that life satisfaction of the elderly was affected by the diverse network, family focused network, the relationship quality with children, the relationship quality with neighbors, and the relationship quality with relatives. Results suggested that having diverse social network in close proximity is very important in old age and structural network types may have important practical implications for improving the quality of life among the elderly.

This study delved into the effects of labor union members' social media utilization for the formation of labor union social capital. Specifically, this study aimed to identify the effects of labor union-related social media use and participation on the labor union's social capital formation through quantitative and qualitative research. It set up trust, network, and participation as social capital components and as dependent variables. Network, in particular, was divided into bonding and bridging aspect. There is the correlation between labor union-related social media use and the formation of labor union social capital. As participation in the group type social media operated by a labor union becomes more active, evaluation on labor union social capital throughout trust, network, and participation is higher. Especially, the correlation between bonding network and bridging network was high. This proves that a labor union's bond enhancement does not result in the labor union's selfishness, but it can build a cooperative system with an external network.

Amid the flood of data, social network analysis is beneficial in searching for its hidden context and verifying several pieces of information. This can be used for detecting the spread model of infectious diseases, methods of preventing infectious diseases, mining of small groups and so forth. In addition, community detection is the most studied topic in social network analysis using graph analysis methods. The objective of this study is to examine signed attributed social networks and identify the maximal balanced cliques that are both absolute and fair. In the same vein, the purpose is to ensure fairness in complex networks, overcome the "information cocoon" bottleneck, and reduce the occurrence of "group polarization" in social networks. Meanwhile, an empirical study is presented in the experimental section, which uses the personal information of 77 employees of a research company and the trust relationships at the professional level between employees to mine some small groups with the possibility of "group polarization." Finally, the study provides suggestions for managers of the company to align and group new work teams in an organization.
