A social phenomenon that occurs in a physical space is said to be a complex system. However, space syntax, which is commonly employed by researchers to identify such social phenomena, has various limitations in interpreting their complexity. On the other hand, agent-based modeling considers a variety of factors including the personality of the agent, objective-oriented work flows, estimation according to time flows and better prediction of space use through diverse parameters depending the situation, as well as the characteristics of the space. The agent-based method thus has the potentials to be developed as an alternative to space syntax techniques. In particular, discrete event driven simulation(DEVS), which is part of the agent-based modeling method, embraces the concept of networks just like space syntax, which allows a possible theoretical linkage in the future. This study suggests a procedural model of agent-based DEVS reflecting two different connection methods, i.e. connections between adjacent areas and those of the entire space, and attempts to identify the relationship between the local and regional indices of space syntax. A number of spaces were selected as examples-one for a preliminary experiment and eight modified for the main experiment-and space syntax and DEVS were applied to each of them. The comparative analysis of the results led to the conclusions as follows: 1) Adjacent connections were closely related to local indices, while the whole-space approach to regional indices. Local integration shows both characteristics. 2) Observation of the time flow model indicated a faster convergence with the range of 1 to 3-fold of the total time of one lap, with the error of less than 10%. 3) The heat map analysis showed more obvious characteristics of using the space for the entire space rather than adjacent connections. 4) Space syntax shows higher eligibility than ABM.

디지털 미디어 환경에서는 이용자의 요구가 새로운 서비스와 콘텐츠를 창출할 뿐만 아니라 새로운 미디어 서비스와 콘텐츠가 이용자의 요구를 새롭게 개발해내면서 컨버전스가 진행되고 있다. 소셜 게임 역시 또 다른 컨버전스 현상을 구현하고 있다. <시티빌>과 같은 소셜 게임은 일과 여가, 노동과 놀이, 사적 영역과 공적 영역의 경계가 허물어지는 상황을 드러내고 있으며, 사회적 상호작용과 사회적 자본의 연결이 어떻게 인맥을 구성하고 견고하게 만들어주는지 보여주고 있다. 또한 <시티빌>은 온라인 상에서 이루어지는 의례적인 커뮤니케이션을 보다 흥미롭고 유연하게 만들어줌으로써 온라인 상에서 축적된 인맥 혹은 인적 네트워크가 사회적 자산이 되는 현상을 드러내고 있다.

The wide spread of smartphones and the growth of the number of internet users are reshaping the SNS (Social Network Service). Merging into other service areas and creating new business models with high profits, SNS is no more a service simply providing personal connections. Now SNS has positioned itself as a service platform. SNG (Social Network Game) is a new outcome utilizing SNS as a game platform and showing a rapid growth rate in a short period of time. The number of SNG users is expected to increase steadily. In this study, we examine whether SNG user motivations lead to flow experience and future intention to use. For that purpose, we conducted a survey with smartphone users. The results indicate that flow experience functions as a mediator and user motivations indirectly affect intention to use through flow experience. This paper concludes with discussions on findings and suggestions for future research.

많은 국내 기업이 사회공헌활동의 하나로 사회적기업과 연계하고 있으나 아직까지도 비주기적 단순 기부형태 위주의 일회성이 대부분이라 할 수 있다. 따라서 본 연구에서는 기업에서 사회책임경영활동을 지역사회에서 체감할 수 있도록 사회적경제를 육성하기 위해 기업의 내부자원을 활용한 지속가능한 사회적경제 비즈니스모델 개발을 연구해 보고자 하였다. 따라서 최근 5년간의 사회적경제 비즈니스 모델 및 일자리 창출 관련 25개 보고서에서 소개된 국내외 123개의 비즈니스 모델을 분석해 본 결과 일자리 창출의 실질적인 성공요소를 내부자원 분석, 비즈니스모델 개발, 실행을 위한 지원활동(프로보노 등)이 성공요인임을 확인하였다. 이를 토대로 DIDOV(Define-Identify-Design- Optimize-Verify)방법론에 따라 외부환경에 따른 정부정책, 기술 환경 등을 파악하고 인천국제공항공사의 내부자원을 조사하여 인천국제공항공사와 연계된 비즈니스모델을 도출하고 평가하여 인천공항공사의 공항서비스와 관련 있는 9가지의 사회적경제 비즈니스모델을 확정하였다.

Purpose: The purpose of this study was to examine the relationship between social support (family, healthcare provider, friends/peer), treatment belief, hope, and health status in patients on hemodialysis, and to identify direct and indirect effects of the variables on patients' health status. Methods: The self-regulation model was used to establish a path model. Data were collected from 240 patients. Multidimensional Scale of Perceived Social Support, Revised Illness Perception Questionnaire, Herth Hope Index, and Medical Outcomes Study Short Form-12 were used. Data were analyzed using the SPSS and AMOS programs. Results: The model was supported by fit statistics ($x^2=3.33$, p=.343, GFI .995, RMSEA .021, AGFI .968, NFI .986, CFI .999, TLI .993). Family and friends/peer support showed a significant direct influence on hope, while healthcare provider support directly influenced treatment belief. Social support, treatment belief, and hope directly and indirectly influenced health status, explaining 28.7% of the variance. Conclusion: These results show mechanisms underlying connections between social support and health status by demonstrating impact of social support and showing treatment belief and hope as mediators between social context and outcomes. To promote health of patients on hemodialysis, it is necessary for patient, family, healthcare professional, and friends to collaborate.

This study aims to develop strategies to reinforce the roles of universities and volunteer service activities centering on promotion of their connections to communities and community-oriented volunteer service activities. First, for autonomous and continuing development of volunteer services, universities should have active connections with service organizations. Second, more specialized volunteer service programs should be developed. Third, as volunteer service activities are somewhat forced on college students, recognition for them should be improved. Fourth, as the quality of the service and academic achievement decrease, conditions for volunteer service education and programs should be made available. Fifth, for continuing participation in volunteer service activities, organized systems should be established.

Social network services have recently changed from environments for simply building connections among users to open platforms for generating and sharing various forms of information. Existing user reputation computation methods are inadequate for determining the trust in users on social media where explicit ratings are rare, because they determine the trust in users based on user profile, explicit relations, and explicit ratings. To solve this limitation of previous research, we propose a user reputation computation method suitable for the social media environment by incorporating implicit as well as explicit ratings. Reliable user reputation is estimated by identifying malicious information raters, modifying explicit ratings, and applying them to user reputation scores. The proposed method incorporates implicit ratings into user reputation estimation by differentiating positive and negative implicit ratings. Moreover, the method generates user reputation scores for individual categories to determine a given user's expertise, and incorporates the number of users who participated in rating to determine a given user's influence. This allows reputation scores to be generated also for users who have received no explicit ratings, and, thereby, is more suitable for social media. In addition, based on the user reputation scores, malicious information providers can be identified.

The goal of the environmental education in High School is to make students survey and work out the issues on environment and to help them continue and improve the work. It is important that we should educate students the rational ability of decision-making. The more they can make decisions rationally, the more they participate actively in that. The purpose of this study is to develope the model of a new teaching-learning method coinciding with the goal of the environmental education of Social studies in High School. This study is backed up by the following developing processes. To begin with, the contents related to environmental problems in Social Studies Curriculum are being investigated. To urge the importance of STS(Science, Technology and Society), 1 will present the righteous understanding of Science in societal contexts, the development of rational decision-making abilities, and the cognitive connections between society and science. For this, 1'm representing a new model of learning-teaching method, backed up by Constructivism, especially Vygotsky's ZPD theory, giving 4 steps from everyday concepts to natural lingistic thought. Based on the above hypothesis, at last I will represent a STS whose topic is a problem of beach preservation because I intend to show the possibility of STS on the environmental education of Social Studies through this study. This study will help us lay a foundation stone of introducing STS in environmental education of Social Studies.

We study the antecedents to tie formation on an (Facebook-like) enterprise social media platform implemented to support cross-boundary connections. Research has produced mixed findings regarding the role of social media in cultivating bridging vs. closed networks. We examine the tie formation patterns of 1,386 enterprise social media users over a two-year period. Specifically, we observe who became (or chose not s become) "friends" with whom at the dyadic level and relate the decisions to various mechanisms that affect one's network to expand, constrain, or bridge. Using logistic and OLS regressions, we find that users tend to form ties via reciprocity and transitivity (with friends of friends), both of which help expand one's network. We also find strong networking tendency toward functional and hierarchical homophily (same business unit and same rank, respectively), which is likely to constrain one's network (closed network structure). We find that one's participation in various online interest groups is likely to open one's network (bridging network structure) while no evidence found for preferential attachment. Overall, we find that enterprise social media offers features, some of which are likely to foster bridging while others foster closed networks via different mechanisms.
