The purpose of this paper is to analyze the effect of land use characteristics of compact city -mixed land use, high density development, job-house match- on CO2 emission in 82 cities in Korea. For this purpose, multiple regression analysis was used using CO2 emission data for 82 cities in Korea as a dependent variable with population density, ratio of mixed land use, job-house ratio, city land area, park area, andwaste volume as independent variables. The study result shows that population density, city land area, and waste volume have positive effect on CO2 emission while mixed land use has negative effect on CO2 emission with statistical significance. Job-house ratio and park area have negative effect onCO2 emission butwithout statistical significance. The study result shows that increasing population density without mixed land use can increase CO2 emission volume in city, indicating that mixed land use can be a more effective measure to reduce CO2 emission in city planning.

The purpose of this study is to analyze the effects of nuclear power plant workers and organizational characteristics on accidents, and seek the combination of policies for reducing accidents. For this purpose, it grasped, by using System Dynamics and Causal Loop Diagram, how various factors that cause accidents in nuclear plants are interrelated, and performed simulations after building simulation models. As a result of the analysis, first, the fundamental cause of safety accidents in nuclear power plants turned out to be the time constraint on the workload. Second, it turned out that as the workload of workers increases, physical and mental stresses increase, thereby increasing accidents due to errors and violations. Third, it turned out that as the levels of educational training and compliance with regulations and procedures are enhanced, accidents are reduced. Lastly, it turned out that as the combination of policies (reliance level + working environment + educational training + compliance with regulations and procedures) is increased, accidents are reduced. Especially, it turned out that if the combination of policies is increased by 30%, more than 10 cases of accidents are reduced.

사회 네트워크 분석기법을 이용한 온라인 공동체의 네트워크 구조 탐색

김병석 ( Byung Suk Kim ),배순한 ( Soon Han Bae ),백승익 ( Seung Ik Baek ) (주)엘지씨엔에스(구 LGCNS 엔트루정보기술연구소) 2012 Entrue Journal of Information Technology Vol.11 No.1

과거의 온라인 공동체는 개개인의 사소한 문제나 소문 등을 공유하는 비공식적이고, 소극적인 미디어였다. 그러나 근자에 들어서는 신문과 방송과 같은 전통적 미디어가 주목하는 정치·경제적 사안 등, 다양한 이슈에 대하여 여론을 형성하는 역할을 하고 있다. 이제 온라인 공동체는 개인이 자유로이 정보와 지식을 공유할 수 있는 공간이라는 개념을 넘어서 하나의 사회적 네트워크로서 정치, 경제, 문화는 물론이거니와 사회 전반에 걸쳐 큰 영향력을 발휘하고 있다. 본 연구에서는 온라인 공동체 내에서 많은 참여자들이 남긴 방대한 규모의 데이터를 체계적이고, 과학적으로 분석할 수 있는 도구로써 ``사회네트워크 분석(SNA: Social Network Analysis)``방법을 제시하고, 이 분석을 통해서 온라인 공동체의 참여자들 간의 상호작용(커뮤니케이션) 패턴을 탐색하여 온라인 공동체의 네트워크 구조가 어떻게 변하는지를 분석하였다. 본 연구를 통하여 초기 온라인 공동체에서는 소수의 오피니언 리더가 존재하고, 그들이 공동체의 정보 생성과 전파에 중요한 역할을 하나, 어느 정도 참여자들의 수가 증가하고, 그들 간의 교류가 활발해지면 소수의 오피니언 리더의 영향력은 크게 감소하게 됨을 발견하였다. 그리고 그 영향력의 감소는 오피니언 리더가 사라지는 것이 아니라 하나의 공동체가 여러 개의 소그룹으로 나뉘면서 소수가 아닌 다수의 리더가 생겨나게 됨으로써 소수의 리더가 존재하는 네트워크에서 다수의 리더가 존재하는 네트워크로 전환됨을 실증적으로 발견하였다. Today`s online community has shown profound impacts as a social network, expanding its sphere of influence across the whole society - not limited to politics, economy and culture. Online community goes beyond personal needs; it even keeps people informed and interested about political and economic issues. The purpose of this study is to investigate how users interact with each other in online communities by analyzing the commenting platform in internet bulletin boards. Social Networking Analysis (SNA) was used for an analysis method. More specifically, we chose actual online communities to see the interactive patterns between users. The results are as following: in its early period, the communities are visited by a small number of people. Information is mainly created and shared by a few influential users; however, once visitors grow in number, more influential users appear. Online communities were run on a small scale by many important members, not by a handful of crucial ones.
