현재의 P2P 시스템은 특정한 분야에서는 성공을 거두고 있지만 지식과 정보 공유의 목적으로서는 활용되지 못하고 있다. 사용자가 웹에서 수집한 자료와 새로 생성한 지식 및 정보 콘텐츠들은 기존의 P2P시스템으로는 공유하기 힘든 몇 가지 이유가 있다. 그 이유 중 하나는 대부분의 P2P시스템은 사용자가 콘텐츠 각각에 대한 메타데이터를 작성하도록 하거나 키워드가 나타나도록 파일명을 수정하도록 요구하기 때문이다. 본 논문에서 제안하는 CONCEPT P2P는 P2P 환경에서 콘텐츠를 공유하는데 개념지도를 사용한다. 개념지도는 시간 소모적인 메타데이터 작성 작업에 대한 대안이 될 수 있기 때문이다 CONCEPT P2P는 로컬 파일 시스템에 수집하고 있는 관심 콘텐츠의 공유를 목적으로 한다. 사용자의 개념지도를 추출하여 개념지도로부터 콘텐츠 묶음을 검색하므로 무리한 수작업이 없이도 다양한 분야의 콘텐츠를 효과적으로 공유할 수 있도록 설계하였다. 또한 다른 사용자와 개념 네트워크를 형성하여 관심 개념에 의해서 클러스터링 되고 있는 복수개의 콘텐츠를 지속적으로 수집하고 배포하는 접근을 취하였다. 개념 지도를 기술하고 검색하는 부분에서는 RDF 기반의 시맨틱 웹 언어와 RDF 질의 언어인 QEL을 사용하였다.

앞으로 전산 시스템에서는 독자적인 사용자의 전산 시스템 이용보다는 조직내의 다수의 작업 참여자간의 의사소통과 정보의 교환 및 공유가 원활히 이루어지도록 할 수 있는 시스템의 지원이 필요하게 되었다. 이러한 전산환경을 CSCW(Computer Supported Cooperative Work)환경이라고 하며 많은 구성원이 공통된 자원을 공유함으로 해서 발생할 수 있는 보안 문제가 발생하게 된다. 이 문제를 해결하기 위한 방안으로 최근 다수의 사용자가 공유자원을 사용하는데 있어 발생할 수 있는 관리의 복잡성을 해결하기 위해 RBAC(Role Based Access Control) 개념이 연구되고 있다. 그러나 CSCW환경과 같이 Work개념이 중요한 환경에서는 기존의 RBAC개념만으로는 공유자원의 접근제어문제 해결에 어려움이 있어 본 논문에서는 Work개념을 RBAC모델에 도입한 CSCW환경 하에서의 RBAC 모델을 제시해 보고자 한다.

To understand the synergy of collaboration and to apply this understanding to education, an analysis of how a team solves a problem and the sharing of their mental models is needed. This paper analyzed two things qualitatively to find out the source of synergy in a collaborative problem-solving process. First, the sharing contents in team mental model and second, the process of sharing the team mental model. Ten gifted middle school students collaborated to solve an ill-defined problem called sunshine through foliage problem. The gifted students shared the following results after the collaboration: First, scientific concept prior to common idea or the idea that all group members have before the discussions; second, unique individual ideas of group members; and third, created ideas that were not originally in the personal mental model. With created ideas, the team model becomes more than the sum of individuals. According to the results of process analysis, in the process of sharing mental model, the students proposed and shared the most important variable first. This result implied that the analysis of the order of sharing ideas is important as much as finding shared ideas. Also, the result shows that through their collaboration, the gifted students' shared mental model became more refined and expanded as compared to their individual prior mental models. It is recommended that these results can be used to measure shared mental model and develop collaborative learning models for students.

The purpose of this study was to define and clarify the concept of Shared decision-making (SDM) in patients with chronic disease. Walker and Avant's concept analysis process was used to analyze interdisciplinary convergence in SDM. SDM in patients with chronic disease can be defined by the following attributes: acknowledgment patients as 'self-care experts', the rights of self-determination, reversible negotiation, and patient-centered care. The antecedents of SMD consisted of situations where there is a need to make a decision from several treatment options of similar efficacy, decisional conflict, patient, family, and health provider's willingness to participate in the decision-making process, enough time and opportunity for SDM. The consequences occurring as a result of SMD were decrease decisional conflict, improvement health outcome, satisfaction, quality of life, enhancement self-management and self-efficacy with long-term, and living acceptably with the illness. Based on these results, a scale measuring SDM in patients with chronic disease is needed.

본 논문에서는 효율적인 의사결정 지원을 위해 SHADE 기반의 공유 데이터 접근 활동들에 대한 절차를 제안한다. 먼저 SHADE에 대한 개념 및 기술구조를 제시하고 공유 데이터 접근을 위해 요구되는 핵심 기술, 즉 데이터 디렉토리 서비스 기술, 데이터 미디에이션, 복제 기술에 대한 개념과 특징을 분석한다. 그런 다음 SHADE 기술구조 하에 효율적으로 공유 데이터에 접근할 수 있도록 4개 활동 각각에 대해 절차를 제안한다. 제안한 절차에는 5단계의 디렉토리 서비스 및 4단계의 검색 절차, 데이터 미디에이션을 이용한 5단계의 데이터 중개 절차, 미들웨어를 이용한 7단계의 실시간 데이터 교환 및 4단계의 데이터 복제절차가 각각 포함된다. 향후 제안한 공유 데이터 접근 절차를 통해 정보체계 간 데이터 연결 능력이 향상될 뿐만 아니라 이를 통해 정확하고, 신속한 의사결정 지원에 도움을 줄 것으로 기대한다.

The purpose of this study is to confirm the components of users' shared value expectation(SVE) on lifelong education through convergent approaches. After reviewing primary data and collecting secondary data with quantitative and qualitative research methodologies, the components of users' SVE on lifelong education were categorized into 10 perspectives, 27 measured variables, and 81 questions. After conducting a confirmatory factor analysis, the latent measurement model was confirmed as reasonable. Internal reliability, construct convergent discriminant validity were also confirmed as reasonable. In a viewpoint that builds interdisciplinary theory, this research may help grasp users' SVE on lifelong education with interdisciplinary approaches. In a strategic viewpoint, this study may contribute to both understanding categorized users' value expectation and planning/executing suitable programs that can meet the expectations. In a managerial viewpoint, this result may help measure the effectiveness of SVE on lifelong education quantitatively.

The main purpose of this study is to empirically examine and to develop the optimal model about an influential relationship between the types of source-based trust and knowledge sharing of local government officials. Procedural and distributive justice-based calculative trust in organization, cognition-based trust in organization, cognition-based trust in supervisor, cognition-based trust in coworkers, and emotion-based trust in coworkers were set up as independent variables of this research model, and sharing of tacit knowledge and explicit knowledge based on the knowledge content as dependent variables. The research results shows that the suitability of each model has approximate value to the required level, and that emotion-based trust in coworkers significantly affects knowledge sharing for both the individual and integrated factors in hypothetical influential relationship. This study is expected to help to enable knowledge sharing in various situations by dividing the concepts of trust that affect knowledge sharing into a few types, and deriving the influential model of knowledge sharing by types.

Why people share location context information? The purpose of our study is that why users share location context information and which factors is related to co-experiences in LBSNS. Through an exploratory approach, first, we conducted a qualitative study in order to understand experiences among people in LBSNS and analyzed according to Grounded Theory. As a result, we found concepts regarding co-experiences cooperatively and competitively in LBSNS. Second, the theoretical model of co-experience was constructed by mediating perceived empathy based on theoretical foundation. In this study, theoretically, we suggested exploratory research model of co-experiences in LBSNS. Practically, designers could adopt concepts in terms of competition and collaboration among users to build co-experience of LBSNS services as its guidelines.

Bicycle-sharing as a product service system in the sharing economy, its characteristic is that users can go to nearby places by the public bike at any time however they don't need to have their own bicycle. However, the service quality of bicycle-sharing and satisfaction of users continuously decrease with the rapid growth number of bicycle-sharing users in China. Based on the double diamond model and from the perspective of service design, this research studies the service experience of bicycle-sharing of Chinese users, focuses on the potential pain points of Chinese users when using the public bike, and designs the optimum proposal to promote users' satisfaction. According to the research result, the research builds a new concept which can satisfy users' demand for communication, enjoyment and option during the cycling. The experience of new service system of bicycle-sharing makes humanized and subconscious interaction possible.
