The study conducts a comparative study of the supporting systems and methods of social enterprises in Korea, Japan, and Hong Kong to propose a policy on sustainable growth of social enterprises and their long-term activation. By investigating previous studies, this researcher drew the frame of a comparative analysis and conducted the comparative analysis. First, regarding the supporting system for social enterprises, it was found that Korea had better institutional foundation and system, whereas Japan had better activation, cooperation and network of intermediary support organizations. In Korea there is the law related to social enterprises, and the government takes control of all of the organization in charge of the policy, intermediary support organizations, cooperation and network, and authentication system. However, Hong Kong has yet to establish a basic institutional system to grow and activate social enterprises, and foreign intermediary supporting organizations increase the network and cooperation level to support social enterprises. Thirdly, for supporting methods for social enterprises, there were direct financial support, indirect business support and other kinds of support in Korea, whereas indirect support was activated in Japan. Although The Hong Kong government barely supports social enterprises, it comes up with a plan to support the firms serving as social enterprises under its the 12th 5-year development plan. For sustainable growth of Korean social enterprises, this study suggested the change of the government policy to the direction of creating social enterprise ecosystem through cooperation and network activation, indirect support in the middle of process, and activation of intermediary support organizations.

This study was carried out to confirm a convergent research pattern and researchers' role in stem cell sector by social network analysis. Articles were extracted from 1996 to 2012 in PubMed, 515 authors of 270 embryonic stem cell and induced pluripotent stem cell articles and 1,515 authors of 580 adult stem cell and mesenchymal stem cell articles. Degree(D) and betweenness(B) centrality was measured and co-author network was generated for researcher's role. As a result, Core researcher and Intermediary researcher was identified in co-author network. Core researcher had high D. centrality, otherwise high B. centrality or not. Intermediary researcher for convergent research had high B. centrality and low D. centrality. Conclusively, co-author network will be used as objective data not only to find core researchers in subject area for improving achievement but also to select experts for research project evaluation.

This study is done to analyze the social function of social games, propose a development model, and demonstrate predisposing factors and consequences on the model. Therefore, the predisposing variables on social functions of social games are explored through related theory and previous studies to propose the social function developing model of social games. Social function model of social games are classified in detail in terms of emotional ties, open communication, sense of belonging to a community and interaction to derive a measure for social function improvement, to prove social function improvement elements through various social network services and social game theories and to propose a social game development model.

The purpose of this study is to analyze the effect of controlling consulting service quality in relation to the factors of success and performances of the social enterprises. In order to achieve the objective of this study, securement of market competitiveness, entrepreneurship and network activity was defined to be the factors of success and the research model and hypothesis was set according to the theoretical basis of the factors of success, performances and the quality of consulting services. The results showed that first, securement of market competitiveness, entrepreneurship and network activities as factors of success all had significant effects on performances pertaining to both profit-making and public interest, having great influence on the securement of market competitiveness of the social enterprises. Secondly, as a result of analyzing the effects of controlling the quality of consulting services in relation to the relationship between the factors of success and management performances of the social enterprises, network activity showed to have significant effect on performances pertaining to both profit-making and public interest. Through this study, the importance and the necessity of the improvement of consulting services and network activities of social enterprises were highlighted and the necessity of a new consulting principle in the consulting industry that can be specialized to social enterprises is proposed.

This study analyzes key word networks of the papers which are published at Korean Journal of Social Welfare issued by Korean Academy of Social Welfare from 1979 to 2015. It aims at investigating the trends of social welfare researches in Korea by dividing the given period into two: 1979-2000 and 2001-2015. It shows the trends in three ways: methodologies, subjects, and intellectual structures. In order to identify intellectual structure, it calculate centrality indices basing on co-appearance frequency of key words. It also derives some values which explain relationship structure of key words by using pathfinder algorithm, and finally visualizes the intellectual structures by using the NodeXL program. Some implications of the findings of these analyses are discussed in the end.

Using the Korean longitudinal study of ageing(KLoSA), this study examines the effect of the participation in physical exercises and in social networking on the experience of depressive symptoms among elderly. This study differs from previous studies in two ways. First, this study avoids omitted variable bias by using an extensive set of control variables that are associated with the experience of depressive symptoms. Second, this study explores the composite effect of two different leisure time activities. This study provides empirical evidence that the participation in physical activities and in social networking reduces the probability of experiencing depressive symptoms. This study provides important insights on the future research on the mechanism how leisure time activities influence physical and mental health of elderly.

최근, 온라인 소셜 네트워크 서비스의 사용자가 크게 늘어나면서 온라인 사용자들의 특성을 연구하기위한 방안으로 소셜 네트워크 분석이 주목받고 있다. 그러나 대부분의 소셜 네트워크 분석 방법은 두 노드 사이의 최단경로를 계산해야하므로 계산 시간이 오래 걸리는 단점이 있다. 본 논문에서는 휴리스틱 탐색방법의 하나인 최상우선 탐색 방법을 온라인 소셜 네트워크에 적합하도록 수정한 최단경로 탐색 방법을 제안한다. 제안한 방법은 그래프에서 아크의 개수를 평가 값으로 사용하는 휴리스틱 함수를 사용하며 탐색의 효율성을 위하여 경사트리를 제거한 후 경로를 탐색한다. 그리고 검증을 위하여 약 16만 사용자로 구성된 실제 온라인 소셜 네트워크를 수집하여 너비우선 탐색 방법과 비교 실험을 하였다. 실험 결과, 본 논문에서 제안한 방법이 너비우선 탐색 방법에 비해 정확도는 80% 정도로 다소 떨어지지만 계산 속도가 약 7.4배 향상됨을 확인하였다. 본 논문에서 제안한 방법은 소셜 네트워크 분석의 시간을 향상시켜 여러 분야에서 사회 현상 및 동향을 다양하게 분석하는데 유용하다.
