The advancement of the Science for complex systems enables the analysis of many social networks. We constructed and analyzed a Korean movie star network as one of social networks, based on the 100 Korean movie selection for a main data source. Until now, the research trend has been the structural analysis of network, focused on link numbers, such as degree, betweenness and clustering coefficient. But it is time that the research is not limited by the structural analysis of networks only. Rather, the research goal should be aimed to an information analysis, performed by identifying and analyzing central modules that are regarded as the core of complex networks, using k-core analysis method. In this research, we constructed a network of movie stars who have appeared in 100 Korean movie selection, provided by Korean movie database, also we analyzed its core modules with and without weights, and the trend of seasonal expansion of the network. We expect our findings can be used as the basic data applicable to a model for understanding of the expansion and evolution of networks.

Intimate friendships and a sense of belonging have positive effects on adolescent's psychological adaptation. Belongingness orientation is the motivation to belong. It is divided into growth orientation and deficit-reduction orientation, both of which have different effects on psychological adaptation and interpersonal characteristics. This study was conducted to determine how adolescents' belongingness orientation affected their psychological adaptation and friend networks. Students in their second year of middle school were surveyed both at the beginning and end of the spring semester. Friend networks were measured through network centrality analysis. Multilevel regression analysis produced three major results. The first major result was that the correlations between growth orientation and loneliness and between growth orientation and stress at the beginning of the spring semester was statistically significant even when friend network centrality was included in the analysis model, but the correlation between deficit-reduction orientation and loneliness and between deficit-reduction orientation and stress were not statistically significant. The second major result was that growth orientation significantly predicted friend network centrality at the end of the spring semester. This effect was significant even when friend network centrality at the beginning of the semester and psychological adaptation level at the end of the spring semester were added to the analysis model. The third major result was that the correlation between friend network centrality at the end of the semester and psychological adaptation level was statistically significant even when psychological adaptation levels at the beginning and the end of the semester were included in the analysis model. This study is meaningful in that it had a short-term longitudinal design and empirically demonstrated the relationship between belongingness orientation and psychological adaptation level of adolescents and between belongingness orientation and the development of friend networks. Lastly, we discussed limitations of this study and provided suggestions for future research.

The deployment of social network service(SNS) makes the social network game(SNG) as the new value added service of SNS be popular. But, a few study had identified the reason of this popularity and the elements of SNG. Based on the social presence theory and media richness theory, we had tried to identify three community artifacts (i.e. persistent labeling, self presentation and deep profiling) and two media characteristics(i.e. vividness and interactivity) as the SNG elements in this research. Then we had empirically validated the effect of these elements on the SNGexperience (i.e. social presence, perceived enjoyment) and behavioral intentions (i.e. Continuous usage intention, willingness to pay and loyalty) of the users. We conducted a survey to the actual SNG users. 243 data were collected and analyzed by PLS algorism. The results indicated that the community artifacts mediated by the social presence and media characteristics could significantly affect on the experiences and behavioral intentions. These findings could contribute to identify what element could be the reason of social network game popularity and could also contribute to design more attractive social network game in practice.

복잡계 과학의 발달에 따라 많은 사회 네트워크들이 분석되고 있다. 우리는 연결선수, 중간성(betweenness), 결집계수와 같은 링크수를 중심으로 네트워크의 구조적 분석에서 나아가 복잡한 네트워크 속에서 핵심 되는 중심 모듈을 찾아 분석하였다. K-core알고리즘은 복잡계 네트워크를 가중치가 낮은 링크와 노드를 단계적으로 제거하여 복잡한 네트워크의 의미를 분석함에 있어 핵심이 되는 모듈을 얻는데 용이하다. 이에 소설, 영화, 과학 교과서, 단백질 상호작용 네트워크와 같은 다양한 분야에 이 알고리즘을 직접 적용해보았다. 그 결과, 각기 복잡한 네트워크로부터 핵심이 되는 모듈을 찾아낼 수 있었고, 전체 네트워크에서는 발견하기 힘든 유용한 정보들을 도출할 수 있음을 확인하였다. 본 연구에서 k-core 알고리즘을 통해 핵심 네트워크를 구축하여 유용한 정보를 도출할 수 있는 가능성을 제시하였다.

초대 이승만 대통령으로부터 제18대 박근혜 대통령 취임사를 네트워크 기반으로 분석하였다. 연합뉴스에서 제공하는 데이터베이스는 역대 대통령 취임사 단어구름으로 보여줌으로써 키워드를 파악할 수 있도록 하였다. 이 경우 특정 단어의 등장 횟수에 비례하여 중심 단어를 찾아주기 때문에 취임사 전체에 흐르는 문맥이나 대통령의 의중을 반영하지 못한다. 이러한 문제를 해결하기 위하여 본 연구에서 18개 대통령 취임사에 등장하는 키워드 네트워크를 구축하였다. 네트워크상에서 허브(hub)에 해당하는 단어를 연결하면 대통령의 의도나 통치 방향을 파악할 수 있다. 대한민국의 18개 대통령 취임사는 네트워크의 동적 변화를 분석할 수 있는 좋은 자료다. 초대 취임사 네트워크에 두 번째 취임사 네트워크를 추가하여 점진적으로 확장되는 네트워크를 구축하여 동적변화를 분석하였다. 네트워크 동적 분석 결과는 시대의 흐름에 따른 대통령 통치 방향과 변화가 담겨져 있기에 대한민국 현대사 흐름을 파악하는데 기여하는 것으로 나타났다. 이제 복잡계를 이해하는 방법의 하나인 네트워크에 관한 연구는 사회현상, 자연현상, 생명현상을 넘어서 대통령 취임사에 이르기까지 다양한 영역에 함축된 복잡한 현상을 이해하려는 시도에 방법론적 실마리를 제공하고 있다.

This study examines the social issues between the central and local governments related with the underground space after happenings of sinkholes in Jamsil area in July, 2014. In this study, we consider the keyword network of the social network analysis as a research methodology. The social issues regarding the underground space have been dealt with through the analysis of the centrality and group density to know the attributes of the network. The results show that the government has been steadily helpful to the local governments for establishing the socialized law for the underground space. This research suggests that the laws and technologies as to the underground space issues cooperate each other in the future. It also shows that the government should enact the policies and the national plans for the development of the underground.
