본 연구는 국내 문헌정보학 분야 학술지를 대상으로 협업 특성과 연구주제를 파악하기 위해 지리적인 측면에서 기관들의 공동연구 특성을 살펴보았다. 기존의 협업 특성을 분석한 연구들은 공저 네트워크의 속성이나 연구자들의 연구생산성, 소속기관 및 국가 비교 등 통계적 측면에 초점을 맞추어 분석을 수행해왔다. 본 연구는 기존 연구에서 주된 분석수단으로 사용해 온 통계적 분석 외에 연구자의 협업 연구주제와 연구자가 속한 기관 및 지역정보를 활용하여 협업 패턴을 파악하도록 하였다. 연구자가 속한 기관들 간의 협업 네트워크를 지리적인 관점에서 연구주제와 함께 직관적으로 파악할 수 있다는 장점이 있다.

의료영상기기의 발달과 등장으로 진단과 치료목적으로 생성된 의료영상은 기하급수적으로 증가하고 있다. 게다가 의료 환경이 보다 전문화, 집중화 되면서 의료기관 간의 협업의 중요성이 강조되고 있다. 의료기관간의 효과적인 의료협업을 위해서는 의료정보의 원활한 가시화와 이를 지원하기 위한 정보 처리는 필수적이다. 의료기관간의 의료정보를 가시화하기 위해서는 안정적이고 다양한 의료정보를 표현하기 위한 플랫폼이 필요하다. 본 연구에서는 다양한 의료정보 협업을 지원하는 의료협업 플랫폼을 제안하고 기존의 PACS-Grid 와 서비스 기반의 의료정보 협업 가시화 서비스를 설명하고자 한다.

To develop a ubiquitous system, several researches have been tried to apply multi-agent models to design a system. Even though current multi-agent models provide many benefits with ubiquitous system developments, there are still some deficiencies in completely supporting the characteristics of ubiquitous systems such as dynamic formation and termination of mission-oriented organizations and interrelationship between organizations. In addition, existing agent-based models only concern aboutananalysis and design of a system, then place a burden of implementation on developers. Therefore, in this paper, we propose the high-level abstraction model of a multi-agent based ubiquitous system and the development process concerning implementation as well as design of systems. In addition, we implemented a development toolkit, called as CDTK(Community computing system Development Tool Kit), then developed a small community computing system using the CDTK.

Jakarta Slide is a WebDAV server developed as one of Apache projects, which supports asynchronous authoring for various contents on the server. Unfortunately, since the WebDAV protocol does not explicitly provide the workspaces for user groups, it is difficult to support complicated collaboration using Jakarta Slide. The CoSlide system is an extension of Jakarta Slide to address this problem, presenting more effective collaborative environment by providing various workspaces for group collaboration. In this paper, we describe the CoJBother Messenger for the CoSlide collaborative system. We developed CoJBother by extending the JBother messenger based on the standard Jabber protocol. To support the users and groups defined on the CoSlide system, we also extended the Jabber protocol. CoJBother shows the information on the CoSlide users and groups in addition to the standard Jabber users and groups. In particular, through CoJBother, the members of a group on CoSlide can initiate group chatting without any administrative overhead.

PECOLE (Peer-to-Peer Collaborative Environment) is a P2P-based multimedia distributed collaborative environment supporting a collaborative workspace which is composed of a variety of collaborative applications such as multi-chat, video conferencing, screen sharing and etc. Unfortunately, due to the PECOLE's simple group management, it is impossible to perform collaboration activities while joining multiple groups. In this paper, we present the design and implementation of PECOLE+ which is an extension of PECOLE. PECOLE+ resolves the drawback of PECOLE by providing the Group Management Service and the Workspace Management Service. The Group Management Service provides functionalities such as creating groups, joining multiple groups, and searching groups, and etc. The Workspace Management Service provides each group with an associated workspace, supporting the execution of collaborative applications over the workspace. In addition, any collaborative applications with the provided plug-in interfaces can be executed over the workspace as a PECOLE+ collaborative application.

In this paper, we propose a social-based collaboration systems for business process management in the mobile cloud. This XMDR-DAI is to provide services for data sharing and exchange between local systems that operate independently in a cloud environment, take charge of a social-based collaborative business process management. Social-based collaborative business processes are handled in a collision among a structure such as unit conversion, meaning conflict, and the schema mapping data resulting from the inner query. The conflict was resolved by mapping process which takes in each XMDR-DAI.

A computer supported cooperative work(CSCW) system is a collaboration system, which enables cooperative works among various participants through the Internet. A collaborative virtual reality environment(CRVE) can be used in scientific research and cultural research because it can provide users with virtual experiences of three dimensional molecular models in cyberspace. However, general CVRE systems are only focused on synchronous collaborations. We propose a remote collaboration system, which provides synchronous and asynchronous cooperation in collaborative virtual reality environment. The proposed system can be applied to bioscience experiments such as molecular docking process, and crystallography simulation. The proposed system is evaluated in performance comparison with previous approaches.

While it is these days, and is increased importance as opposed to design management in managing a construction business necessity as opposed to collaboration business design management between collaboration business business company is regarded as important. An object was put in deriving a flow of a design process about the design management business and a grasp, management element as opposed to management by reason of the first, building design business ability improvement by a study of a book hereby, and an alternative plan of collaboration business design management for use in design optimization of difficulty of a disagreement, workshop modification city design information chase between books by lack of collaboration business between things of each minimization, company was shown with, air in a base in problems grasp as opposed to a collaboration business design by the second" work-site operations and a design process management element. Therefore, this thesis is going to show expected effect of a project about collaboration business design management through systematic practical use about a collaboration business design.

The purpose of this study is to verify the practical effectiveness of the constructivism education theory in building information modeling (BIM)/integrated project delivery (IPD) collaboration education by determining education methods that are most relevant to collaboration in the interaction process. We propose a BIM training model that enhances students' satisfaction in class and collaboration. We aim to identify interrelationships between BIM collaboration education and constructivism theories, examining constructivism methods in BIM/IPD classes to discern which are the most suitable for improving and enhancing collaboration and the proposed education model.

ACE (Advanced Collaboration Environment) [1] aims to provide people to have remote collaboration as they are in the same Space. To provide tele-presence in remote collaboration, quality of audio and sharing of view which can show overall environment. Visual Sharing focuses on providing interactive view sharing among remote participants. A user can see remote collaboration space from any direction and can share his working screen view with others. In this paper, we summarize the development plan of Visual Sharing and relevant elementary techniques for developing Visual Sharing.
