The purpose of the study was to generate the candidate items for the Adolescent Friendship Social Capital Scale. Both inductive and deductive approaches were used to generate the scale items. Halpern's conceptual map of social capital served as the theoretical basis of this scale, and guided the development of items. Semi-structured interviews with adolescents in Sydney, Melbourne and Beijing generated the initial pool of scale items. Twenty-six items were generated for the Adolescent Friendship Social Capital Scale. The items are organised in four theoretical constructs: Bonding Networks, Bridging Norms, Bridging Sanctions, and Linking Networks. Each item is a short statement followed by a five-point Likert scale anchored by 1= "Strongly disagree" and 5= "Strongly agree". The scale has several advantages over previous measures of adolescent friendship networks and friendship social capital. The scale has a strong and clear theoretical structure, the scale items demonstrate initial construct and content validity, and the format of the scale enables the collection of continuous data. However, in order to ensure the validity and reliability of the scale, another two stages of research need to be conducted in the future: scale development and scale evaluation.

Friendship network characteristics, friendship quality, and popularity status were examined for 298 first and third graders(M age=7 yrs., 3 mo. and 9 yrs., 2 mo.). Children provided friendship nominations and responded to the Friendship Quality Scale(Rhee & Koh, in press). Results indicated that 3rd graders had larger friendship networks and more supportive friendship than 1st graders, and girls reported more reciprocal friends and more supportive friendships than boys. The best predictor for friendship satisfaction was a reliable alliance. The higher the reciprocity in friendship choice, the higher the perception of friendship functions and satisfaction. Unpopular children were less likely than popular children to have a reciprocal friend, although friendless children were found in both groups.

The purpose of this study was to investigate the moderating effects of a size of the friendship network and quality of friendship on the associations between mutual antipathy and maladjustment. The subjects were 678 fifth- and sixth-grade primary school children who were recruited from a public school in Bucheon City. The Peer Nomination Inventory was used to assess mutual antipathy, peer victimization, social withdrawal, aggression, and the friendship network. The children were given a classroom roster and asked to nominate up to three classmates who fit each description. Additionally, the children reported the quality of their friendships using the Friendship Quality Scale. Each child was asked to indicate his or her one best friend and rate how accurately a sentence describe done of their best friends on the scale. The results revealed that the friendship network and friendship quality significantly moderated the relationships between mutual antipathy and social withdrawal, and peer victimization. The magnitude of the association between mutual antipathy and social withdrawal was not significant for large friendship networks and high quality friendships. Although mutual antipathy was significantly associated with peer victimization, the association was stronger at lower levels than at higher levels of the friendship network and quality. However, there was no moderating effect of the friendship network and quality on the association between mutual antipathy and aggression. A large friendship network and high quality friendship could be protective factors among those who have mutual antipathy in peer groups.

The present study investigated the effect of area-specific social networks on urban workers life satisfaction. For this, 356 adults over age 20 were interviewed from June 17th 2013 to June 29th 2013. The findings are as follows: First, the closeness of family network index demonstrates that participants with higher affective support have higher life satisfaction. In addition, stronger extended family network brings more life satisfaction and so does a bigger friendship network. Secondly, the extended family network explains 17.6% of the variance in social networks follows by family network, other network, and friendship network, respectively. The closeness variable of social networks yields statistical significance on all categories of networks. The affective support level in the closeness variable of social networks shows differences as well; family network positively associates with life satisfaction. The purposes of this research are to investigate the actual conditions of urban workers' life satisfaction and the influence of family, extended family, friendship, and other variables on life satisfaction. If social networks have an influence on life satisfaction, to find the domain of social networks that holds the most influences on life satisfaction is an important ground in the process of implementing regional welfare.

차량 애드 혹 네트웍 (VANET)은 모바일 애드혹 네트워크의 일종으로써 차량 간의 임시적인 통신을 가능케 한다. VANET의 모바일 노드는 네트웍의 일원으로 참여하면서 에너지와 자원을 사용한다. 몇몇의 노드는 다른 노드와 협력하는 대신에 자신의 이득만을 취하려고 하는 이기성을 가지고 있다. 이러한 이기성을 가진 노드들로 인해 데이터 접근성과 네트웍의 효율성이 감소하게 된다. 이 논문에서는 새로운 기법인 VANET 그룹에서 이기성을 갖고있는 노드를 제거하는 Friendship-VaR을 제안한다. Friendship-VaR은 이기성을 갖고있는 노드를 제거하고 믿을 수 있는 노드들간에 데이터 공유를 가능케 한다. Friendship-VaR는 간단한 데이터 교환을 통해 노드의 이기성 여부를 결정한다. 실험 결과는 제안한 기법이 기존의 기법에 비해 데이터 접근성이 좋아짐을 보여준다.

Purpose: The purpose of this study was to explore the characteristics of social networks among registered nurses in acute nursing care units. Methods: This study used a survey design. Four nursing units from two acute hospitals were selected using a convenience method, and 83 nurses from those nursing units participated in the study in July 2022. The positive influences among nurses included friendship, collaboration, advice, and referent networks, and the negative influences included avoidance and bullying networks. Using the NetMiner program, the k-means clustering technique was applied to create groups of nodes with similar characteristics. The general characteristics of the participants were analyzed by mean, standard deviation, frequency, and ANOVA or chi-squared test. Results: As a result of dividing the 83 nurse participants into four clusters, positive influencers, silent peers, unwelcome peers, and active bullies were identified. Positive influence group nurses were frequently mentioned in the friendship, collaboration, advice, and referent networks. On the other hand, nurses in the unwelcome group and the active bullying group were frequently mentioned in the avoidance and bullying networks. Conclusion: Social networks that have a positive or negative impact on nursing performance are created through different relationships between nurses. Nurse managers can use the findings to create a more supportive and collaborative environment. Further research is needed to develop intervention programs to improve interactions and relationships between fellow nurses.

본 연구는 간호단위의 사회연결망을 과업조언 연결망과 친교연결망으로 구분하여 구조적 특성을 파악하고, 간호사의 조직몰입, 이직의도와의 관계를 분석하기 위해 시도되었다. 4개 병원, 30개 간호단위에서 근무하는 420명의 일반간호사를 대상으로 하였으며, 자료는 UCINET 6.0, SPSS 20.0과 HLM 7.0을 이용하여 분석되었다. 과업조언 연결망에서는 수간호사의 연결정도 중심성이 조직몰입에, 간호단위의 밀도가 이직의도에 영향을 미치는 것으로 나타났다. 친교연결망에서는 수간호사의 근접중심성과 책임간호사의 매개중심성이 조직몰입에, 간호단위의 밀도와 책임간호사의 매개중심성이 이직의도에 영향을 미치는 것으로 나타났다. 본 연구 결과를 통한 간호사들 사이에 형성되는 사회연결망에 대한 이해를 바탕으로, 적절한 인력 배치를 위한 연결망 구조와 기회, 조건을 개발하고 다양한 형태의 전략을 수립하기 위한 이론적 근거를 제공할 수 있을 것이다.

The purpose of this study was to investigate the characteristics of the social networks and its relationship with the psychological well-being of middle-aged men. The participants were 314 men who were married living in Pusan, aged between 40 and 59, having occupation and children. Data were collected by questionnaire which consists of Social Networks Scale and Psychological Well-being Scale. The major results of the study were summarized as follows; First, the range of the social contact with men's own kin was wider than women's. In the contact frequency of midge-aged men, primary networks were shown more frequent contact than the secondary networks. In the characteristics of interactive function of social networks, kinship of the middle- aged men, their partners and friendship networks were the most important among the six networks, which agrees the fact that kin are still the primary source of social support. Second, the level of psychological well-being was lower than family-related satisfaction and work-related satisfaction. In the work-related satisfaction, the level of job satisfaction was lower than the other sub-categories. Psychological well-being of middle-aged men were affected by Social economic status as well.
