A company regards knowledge shared and used within a corporate organization as intellectual capital linked to corporate competences. A great deal of research has been conducted in the past to identify knowledge sharing among knowledge workers. Some papers focus on information technology for automated, efficient, and explicit knowledge sharing. Other papers emphasize the role of social networks to identify the flow of tacit knowledge. Though the role of CoP(Community of Practice) is emphasized to facilitate knowledge management among workers, it is not an easy task to identify the potential members of CoP without voluntary participation of the workers. In this study we adopt a social network approach to analyze knowledge propagation and to identify the potential members of CoP. We suggest a framework for classifying knowledge workers and the result of feasibility study.

This paper proposes a job matching function that calculates the job matching probability of a job-seeker to an employer taking the working conditions of a job-seeker and an employer into account. In addition, this study analysis the degree of centrality that means interactions of a job-seeker and an employer utilizing social network analysis. The results are follows. First, a degree of centrality is found to be severely concentrated in certain job-seekers or certain employers; in addition, there are many job-seekers and employers who have no matching results. Second, according to decision tree analysis, characteristics of a job-seeker that influences the degree of centrality are gender, age and degree of education in order of importance. The characteristics of a employer that influences the degree of centrality are proposed salary, industry classification and firm size in order of importance.

The purpose of this paper is to measure the clustering change and analyze empirical results, and choose the clustering ports for Busan, Incheon, and Gwangyang ports by using Artificial Neural Network, Social Network, and Tabu Search models on 38 Asian container ports over the period 2007-2016. The models consider number of cranes, depth, birth length, and total area as inputs and container throughput as output. Followings are the main empirical results. First, the variables ranking order which affects the clustering according to artificial neural network are TEU, birth length, depth, total area, and number of cranes. Second, social network analysis shows the same clustering in the benevolent and aggressive models. Third, the efficiency of domestic ports are worsened after clustering using social network analysis and tabu search models. Forth, social network and tabu search models can increase the efficiency by 37% compared to that of the general CCR model. Fifth, according to the social network analysis and tabu search models, 3 Korean ports could be clustered with Asian ports like Busan Port(Kobe, Osaka, Port Klang, Tanjung Pelepas, and Manila), Incheon Port(Shahid Rajaee, and Gwangyang), and Gwangyang Port(Aqaba, Port Sulatan Qaboos, Dammam, Khor Fakkan, and Incheon). Korean seaport authority should introduce port improvement plans by using the methods used in this paper.

국제연합에서는 $15{\sim}24$세의 젊은이를 청소년이라고 정의하고 있는데 그 중에서도 특히 농촌청소년은 미래 농촌발전의 핵심주체라 할 것이다. 일반적으로 농촌청소년은 그들 부모세대보다 더 높은 교육수준과 도전의식 그리고 더 높은 창의성을 지니고 있기 때문이다. 더욱이 그들은 미래가 자신의 장래와 직접적으로 연결되어 있기 때문에 장기적인 전망, 미래의 비전에 관심이 크다. 청소년에 대한 교육은 민주사회의 미래에서 한 사회가 할 수 있는 가장 중요한 투자 중의 하나라고 인식되며 현재 진행되고 있는 고도의 경쟁적인 시장경제로의 진입에서 청소년의 사회경제적 비전을 향상시키기 위해서는 교육과 훈련의 질적 양적 향상이 최우선시 되어야 할 것이다. 세계무역기구 출범 이후 농산물 수출국가와 선진국에서의 소득균형은 일반적으로 향상되었으나 순식량 수입국가나 개발도상국가에서는 소득균형이 더 악화되고 농업영역의 쇠퇴를 초래하고 있는 부작용이 국제연합 식량농업기구 등의 분석이다. 더욱이 식량안전상황은 농산물의 급격한 수입으로 여전히 불안하고 농가 판매의 지속적인 악화, 농촌과 도시간의 소득격차가 큰 것으로 나타났다. 특히 인간의 건강과 환경에 유해한 유전자조작 농산물 (GMO)의 교역은 소비자의 식품안전과 잠재적 위해 때문에 합당한 조치가 요구되고 있는 실정이다. 이러한 상황에서 농업교육, 연구 그리고 지도, 특히 아시아의 주요작물 영역에 대한 더 많은 투자가 필요하며 많은 아시아국가들에서 우선적으로 요구되는 농촌 청소년교육은 빈곤퇴치, 식량의 안정적 공급 및 식품의 안전 그리고 지속적이고 균형있는 농촌개발 등이다. 이를 위한 정부와 국민, 특히 농촌 청소년들의 연결망을 통해 함께 협력해야 빈곤퇴치와 식량의 안정적 공급 및 식품의 안전 등 농촌의 사회경제적 발전이 가능할 것이다. 이 연구에서는 아시아지역 농촌사회 및 식량농업의 발전을 위한 청소년 연결망을 예시적으로 검토하고 미래사회에서의 협력을 위한 접근을 탐색하였다.국제연합에서는 $15{\sim}24$세의 젊은이를 청소년이라고 정의하고 있는데 그 중에서도 특히 농촌청소년은 미래 농촌발전의 핵심주체라 할 것이다. 일반적으로 농촌청소년은 그들 부모세대보다 더 높은 교육수준과 도전의식 그리고 더 높은 창의성을 지니고 있기 때문이다. 더욱이 그들은 미래가 자신의 장래와 직접적으로 연결되어 있기 때문에 장기적인 전망, 미래의 비전에 관심이 크다. 청소년에 대한 교육은 민주사회의 미래에서 한 사회가 할 수 있는 가장 중요한 투자 중의 하나라고 인식되며 현재 진행되고 있는 고도의 경쟁적인 시장경제로의 진입에서 청소년의 사회경제적 비전을 향상시키기 위해서는 교육과 훈련의 질적 양적 향상이 최우선시 되어야 할 것이다. 세계무역기구 출범 이후 농산물 수출국가와 선진국에서의 소득균형은 일반적으로 향상되었으나 순식량 수입국가나 개발도상국가에서는 소득균형이 더 악화되고 농업영역의 쇠퇴를 초래하고 있는 부작용이 국제연합 식량농업기구 등의 분석이다. 더욱이 식량안전상황은 농산물의 급격한 수입으로 여전히 불안하고 농가 판매의 지속적인 악화, 농촌과 도시간의 소득격차가 큰 것으로 나타났다. 특히 인간의 건강과 환경에 유해한 유전자조작 농산물 (GMO)의 교역은 소비자의 식품안전과 잠재적 위해 때문에 합당한 조치가 요구되고 있는 실정이다. 이러한 상황에서 농업교육, 연구 그리고 지도, 특히 아시아의 주요작물 영역에 대한 더 많은 투자가 필요하며 많은 아시아국가들에서 우선적으로 요구되는 농촌 청소년교육은 빈곤퇴치, 식량의 안정적 공급 및 식품의 안전 그리고 지속적이고 균형있는 농촌개발 등이다. 이를 위한 정부와 국민, 특히 농촌 청소년들의 연결망을 통해 함께 협력해야 빈곤퇴치와 식량의 안정적 공급 및 식품의 안전 등 농촌의 사회경제적 발전이 가능할 것이다. 이 연구에서는 아시아지역 농촌사회 및 식량농업의 발전을 위한 청소년 연결망을 예시적으로 검토하고 미래사회에서의 협력을 위한 접근을 탐색하였다.

Recently Korean film industry has continuously experienced a rapid growth and expanded its influence to foreign countries. Accordingly, there have been numerous studies in various research areas to investigate the characteristics of the industry. In this study, we applied social network analysis based on the attributes such as genres, ratings, distributors, nationalities, sizes, and profitability to divide the movies into several clusters with respect to their similarity. Results suggested that the ratings and nationality rather than the genre are the major factors to divide the motion picture market into clusters and the profitability also varies much across the clusters. Furthermore, estimation of the diffusion model showed the positive relationship between the success of a movie and the word-of-mouth effect, while the relatively unsuccessful titles exhibited a monotonic decreasing diffusion pattern with the high initial demand and the early peak time.

This study aimed to present that the understanding of the relational structure among stakeholders of a national park with the usage of 'social network analysis' can help more effectively to diagnose conflicts among stakeholders and to resolve them, Conducting a telephone-interview survey with 12 stakeholders of the Taean-Haean National Park, Republic of Korea, this study examined their perception of conflicts related to the park, and compared their social networks when their conflicts emerged with their networks when the conflicts did not appear. When the conflicts appeared, the more respondents tried to seek other information sources apart from the Korea National Park Service (KNPS) and the fewer interactions among the stakeholders occurred than when the conflicts were not present. Based on the findings, it was suggested that KNPS need not to directly distribute information to the stakeholders, and to create the third party to generate more interaction and cooperative relationship among the stakeholders, Thus, it can be said that the employment of social network analysis is worth being employed in the study of conflict management in national parks.

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.
