The purpose of this research is to suggest implications for the elderly with disability by taking a look at the influence of disability of elderly on successful aging and a moderating effect of social support network. This study analyzed the $4^{th}$ panel data from KReIS and the subjects for this research are 3,906 of elderly aged over 65 years. For the statistical analysis, the IBM SPSS Statistics v23.0 program was utilized. Technical statistics was verified, multiple regression analysis was used in order to take a look at the effects of moderating variable. The results of this research are as the following: Firstly, the disability of elderly had an negative effect on successful age. Secondly, as a social support network, friend & neighborhood network and family network had an positive effect on successful age. Thirdly, friend & neighborhood network among social support network had a moderating effect on successful aging. In other words, the more disabled the elderly are, the lower the level of successive aging became, it turned out that the bigger the social support of friend & neighborhood network, the less the negative effect of disability on successive aging. On the basis of the result, it was proposed a case management for the elderly with disability, assurance of mobility right, and self-help meeting program for social support network.

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.

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.

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 purpose of this study is to examine the impacts of smartphone use on structured social network types in the Korean elderly population. Data was derived from the 2014 survey of living conditions and welfare needs of Korean older persons collected by Korea Institute for Health and Social Affairs. A total of 4,180 participants were selected for the Propensity Score Matching (PSM) analysis. Based on propensity score estimates, the 491 smartphone users (treatment group) and 491 featurephone users (control group) were matched. Ordinary Least Squares (OLS) regression analysis was conducted to examine the relationship between smartphone use and structural social network types. The results showed that among retired older adults, people using smartphone had significantly better structured social networks than those using featurephone even after controlling for covariates. Smartphone users had the higher levels of social contact and social activity. These findings suggested empirical evidence that using smartphone positively affects structured social networks, which might be used as the basis for designing intervention programs to promote social networks and social engagement of retired older adults.

This paper deals with visualization that can appropriately show the characteristics deduced from relationships between pieces of information. The visualization of influence, which is used as an important index in deducing the characteristics of relationships in social network analysis, was selected as research topic, and first, the elements that show relationships within the network and the index that show influence were classified and organized. Second, the links between relational elements that show influence in social network were examined, and an influence visualization network was created. Third, an influence visualization framework was proposed which explains the interaction between social network analysis and visualization process. The influence visualization network and framework being proposed in this paper can be used not only to understand and analyze the elements that influence social network but also to make it possible to have a rational and efficient approach to network visualization. Hopefully, they will become a new methodological approach to information design.

This study aims to investigate peer socialization processes on early adolescents' prosocial behaviors in friendship networks. A longitudinal social network model (SIENA) was used to disentangle socialization process in prosocial behavior. Participants were fourth and fifth graders in South Korea from 39 elementary school classrooms (N=1,040, 48% girls). According to results, students select friends based on similarity in prosocial behavior (peer selection) was found in both prosocial behaviors. Peer influence effects were also observed in prosocial behaviors. Also, moderating effect of social relatedness was significant. In classes with high social relatedness, influence effect of prosocial behavior was significant. As a contrast, prosocial behavior was not socialized in classes with the low social relatedness. Results suggest that peernetwork play a critical role in the co-evolution of friendships, and prosocial behaviors. Findings yielded the importance of the socialization process and promoting healthy peer socialization environment.

The purpose of the study was to investigate the effects of social network centrality variables on students' performance in blended learning environment in a higher educational institution. Using data from 36-student course on Learning Theories and Their Implications on Instructional Design Practices, the researcher empirically tested how social network centrality variables - such as friendship network centrality, advice network centrality, and adversary network centrality - are correlated with academic achievement measures. Results indicate, as hypothesized, the friendship and advice centrality positively correlate with, whereas the adversary centrality being negatively correlate with application performance measures and test scores. The size and quality of posted online discussions are positively and strongly correlated with the advice network centrality.

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.

본 연구의 주제는 정보의 관계를 사용자 중심으로 시각화하는 것이다. 생활속에서 제공되는 대부분의 정보들은 보이지 않는 연결성을 가지고 있다. 이런 정보들의 공통적인 특성 및 관계의 연구를 통해 정보의 중요도를 측정할 수 있고, 각 정보의 개체 간의 연결성이 형성되어 인접정보의 접근이 용이해진다. 특히 인간관계는 사회 연결망의 주된 관심사이며, 사회의 각 개체 간 관계를 분석하여 도식화하는 여러 방법론이 제시되어 있다. 이번 연구를 위하여 제한된 사회라고 볼 수 있는 그리스 신화를 소재로 선정하여 등장인물들 간의 관계를 파악하는데 사회연결망 이론을 적용하였다. 하지만 시각화 측면에서 볼 때 현재 제공되는 사회 연결망 분석 도구는 사용자를 고려한 디자인 부분이 배제되어 단순히 정보를 일방적으로 보여준다는 한계를 지니고 있다. 미톨로지아에서는 분석된 자료를 바탕으로 사용자가 정보를 파악하는데 좀더 효과적이고 용이한 시각적인 구성을 가질 수 있도록 시도했다. 사회 연결망 분석법으로 그리스 신화의 인물들이 가진 신분, 출현 빈도, 감정관계 등을 수치화하여 인물의 연결성을 분석하였다. 또한 정보와 사용자 간의 상호작용 기능을 제공함으로써 사용자의 이해도를 높였다. 기본 인터페이스는 인물노드에 쉽게 접근할 수 있도록 4 가지 분류에 의한 인덱스의 형태를 가지며, 인물 간의 세밀한 관계는 선택에 의한 줌-인(zoom in) 기능을 통해 볼 수 있다. 이는 기존의 필터링 기능과는 차별적인 요소로서 직접 관련된 정보 이외의 정보들은 시각적으로 제한되어 사용자가 인물 관계를 빠르고 직관적으로 파악할 수 있다. 미톨로지아는 개괄적인 관계를 보여주는 레이아웃과 부분적이며 상세한 정보를 파악하기에 적합한 인터랙션 방법을 제시한다.
