This study aims to examine online students' informal information seeking behavior during their loaming process and online loaming environments to support their informal information needs. The participants of the study were 29 online students in the Professional Development Studies of Rutgers University. Data was collected by the questionnaire and was analyzed with content analysis and descriptive statistics. This study focuses on when and why online students need human interaction to solve their learning problems and how they communicate with others to meet their informal information needs. Moreover, how online students think about their personal communication opportunities and the functions of their online learning system to support their loaming problems is also examined. Finally, online students suggest the ways to effectively support personal communication needed during learning process in online teaming systems. Based on the findings of this study, a few considerations are suggested in conclusions.

The prior studies on the practical lawyer's information seeking behaviors, including Leckie et al. (1996) model showed that role of the work and nature of the work in attorney's practices had an significant influence on the attorney's information seeking behaviors. This study now asks if these prior analyses can be applicable to attorneys' practices nowadays. This study performed surveys and interviews with 21 practical attorneys in korea who were grouped by their experience period and the size of law firms. This study concludes that role of the work in Leckie et al. model still affects the attorneys' information seeking behaviors today and moreover, the attorney's experience and the size of law firms as variables also have made an impact on attorney's behaviors so far. By the way, this study further finds that the attorneys prefer the digital information in online database and formal information like statutes or case laws. These results are definitely different from them of the prior studies. In addition, this study suggests that the behavior such as meaningful using of the informal information in difficulties with improper information can be kinds of the attorney's information seeking behaviors.

Collaborative filtering has been popular in commercial recommender systems, as it successfully implements social behavior of customers by suggesting items that might fit to the interests of a user. So far, most common method to find proper items for recommendation is by searching for similar users and consulting their ratings. This paper suggests a new similarity measure for movie recommendation that is based on genre interest, instead of differences between ratings made by two users as in previous similarity measures. From extensive experiments, the proposed measure is proved to perform significantly better than classic similarity measures in terms of both prediction and recommendation qualities.

본 연구에서는 질문지법을 이용하여 과학기술분야 연구자들의 정보요구를 파악하고 이를 바탕으로 정보요구별 탐색행태를 분석하였다. 분석결과, 특정 정보요구에 대해 비공식 커뮤니케이션 채널이 정보탐색에 중요한 영향을 미치는 것으로 나타났으며, 탐색과정에서 이용자가 느끼는 정보부족의 원인에 대해서는 정보요구별로 어느 정도 차이가 있는 것이 확인되었다. 반면, 정보탐색환경에서 연구자들이 중요하게 생각하는 요소는 정보요구별로 큰 차이가 없는 것으로 나타났다. 정보요구를 바탕으로 과학기술분야 연구자의 탐색행태 분석결과를 적용함으로써 이용자 특성에 따라 개별화된 과학기술 정보 서비스를 기대할 수 있다.

This paper deals with the extension of and discussion on the System Dynamics model (Jeong & Jeon, 2005) of river crabs in Korea. The previous model has been elaborated to empirically search for the optimal restoration and harvest rates of crabs in the Imjin River, on the basis of theoretical models of population dynamics in the field of bio-mathematics and environmental economics. In this paper, the authors tries to couple a series of new feedback loops related to density restrictions and cannibalistic behaviors with a stage-structured model of the crab ecosystem, and also to endogenize the parameter of baby crabs' survival that is caused by water quality improvement and income increase. Through these extensions and relaxations, the authors are able to argue about the strategic decision of the optimal rates additional considerations as well as the properties of the integrated system that was not covered in the previous paper.

This study examined the impact of late-life poverty on self-rated health, focusing on the mediating and moderating effects of health behaviors and social support. Despite the significant associations among poverty, health behaviors, and health outcomes, little studies have tested complex structural pathways among them. Thus, the purpose of this study is to identify multiple causal pathways between poverty and self-rated health, mediated and moderated by health behaviors and social support. To test the structural pathways, the structural equation modeling was utilized using the 2006 Korean Longitudinal Study of Aging data. The results of this study indicated that poverty had the direct negative impact not only on the health behaviors such as smoking and lack of regular exercise but also on the self-rated health. In addition, regular exercise significantly mediated the relationship between poverty and self-rated health. Finally, informal social support from family and friends buffered the negative impact of poverty on the self-rated health. Findings suggested that providing informal social support to the low income elderly is important in addition to the economic support. It is also necessary to develop programs for promoting healthy behaviors, especially regular exercise.

This paper reports investigation of informal communication among Korean biological scientists. Scientists at the research front communicate informally each other and social organization based upon this communication relation is identified. Seventy-four percent of the scientists are joined together in a large communication network which includes all of the most productive and communicative scientists. Central scientists are the nodal points for dissemination of information as well as important information sources.

본 연구의 목적은 상황 인식 위치 기반 서비스를 위해 정성적인 개인 공간 행동을 포착하는 새로운 방법을 제안하는 것이다. 단순한 추적이내 사람의 위치 변화에 대해 색인 생성을 넘어서서, 사람과 환경 사이의 관계 변화가 본 연구의 공식 모텔에 대한 기본 소스로 간주된다. 특히 이 연구는 특정 지역의 경계 근처에서의 사람의 움직이는 행위에 중점을 둔다. 그 행위를 포착하기 위해 그 개체의 영향력 범위를 적용하는 새로운 접근 방법이 제안된다. 이러한 개체 시공간적으로 확장된 점는 그 영향력 범위를 그 개체의 위치와 함께 잠재적 사건이내 상호작용 구역으로 간주한다. 이렇게 포착된 정성적 공간 행위는 알려진 지역 근처의 개체 관계의 더 정제된 설명을 제공하여 단순한 공간정보 제공을 넘어선 실시간 공간 의사 결정 지원 시스템 강화에 도움을 줄 수 있다.

이 논문의 주요 목적은 중국의 남중국해에 대한 정책을 평가하는 것이며, 해양갈등 및 위기 상황과 관련된 사건을 관리하기 위한 중국의 접근을 분석하는 것이다. 주된 핵심은 중국의 남중국해에 대한 영유권 주장, 중국과 남중국해 인접국과의 분쟁 그리고 중국과 베트남 간 사례를 통해 분석된 분쟁 관리에 있어 중국의 행태, 접근방식 그리고 시각이다. 중국과 베트남과 같은 양자간 분쟁에 있어 남중국해 통킹만에서의 분쟁해결 사례는 강조될 수 있는 사례이며, 이는 중국이 인접국과의 분쟁을 공식적으로 해결한 첫 번째 사례였다. 결국 이 논문은 이를 근간으로 향후 중국이 어떻게 남중국해 현황을 관리할 것인가에 대해 넓은 논쟁을 결론으로 제시하고 있다.
