Jakarta-Slide는 Tomcat 웹서버의 WebDAV 프로토콜 지원 모듈로서 인터넷을 통하여 다양한 콘텐츠의 비동기적인 협업을 지원한다. CoSlide 협업시스템은 이러한 Jakarta-Slide를 사용하여 효과적으로 협업을 지원하는 시스템이다. CoSlide 협업시스템은 협업을 위한 가상공간을 제공하며 다양한 클라이언트를 통하여 가상공간에 자원을 등록하고 관리할 수 있다. CoSlide 협업시스템을 많은 사용자나 그룹이 사용하게 될 경우 가상공간과 자원에 대한 효과적인 관리가 필요하다. 하지만 현재의 CoSlide 협업시스템에서는 이러한 가상공간과 자원에 대한 전문적인 관리 기능을 지원하는 도구가 지원되고 있지 않기 때문에 관리 작업이 비효율적으로 이루어지고 있다. 본 논문에서는 CoSlide 협업시스템의 관리 도구 개발에 대하여 기술한다. CoSlide 관리 도구는 Tomcat Administrator Tool을 확장하여 구현되었으며, 효과적인 가상공간과 사용자 관리 기능을 제공한다. 시스템 관리자는 CoSlide 관리 도구를 통하여 협업에 참여하는 사용자를 추가하거나 삭제할 수 있으며 이러한 작업에 따라 개인 가상공간이 자동적으로 관리된다. 또한 그룹 가상공간의 정보를 제공하며 참여하고 있는 사용자들을 파악하고 등록된 가상공간에 대한 정보를 제공하여 효과적인 관리 기능을 제공한다.

The purpose of this study is to explore a collaborative start-up space(Co-Space) configuration plan in terms of university-regional linkage through demand analysis on the composition of university-regional linkage startup space. To this end, a survey was conducted for request analysis, and the collected data were analyzed through the t-test, The Lotus for Focus model. In addition, FGI was implemented for entrepreneurs, and the direction of the composition of the university-region Co-Space was derived from various aspects. The results of this study are as follows. First, as a result of the analysis of the necessity of university-community Co-Space, the necessity of opening up the start-up space recognized by local residents and the necessity of building the start-up space in the region were high. In addition, men recognized the need to build a space for start-ups in the community more highly than women did women. Second, as a result of analysis of demands for university-regional Co-Space, the difference between current importance and future necessity of university-regional Co-Space was statistically significant. Third, as a result of analysis on the composition of the startup space by cooperation between universities and regions, different demands were made for composition of the startup space considering openness and closeness, and for composition of the startup space size. The implications of the study are as follows. First, Co-Spaces need to be constructed in conjunction with universities in accordance with the demands of start-up companies in the region by stage of development. Second, it is necessary to organize a customized Co-Space that takes into account the size and operation of the start-up space. Third, it is necessary to establish an experience-based open space for local residents in the remaining space of the university. Fourth, it is necessary to establish a Co-Space that enables an organic network between local communities, start-up investment companies, start-up support institutions, and start-up companies. This study is significant in that it proposed the regional startup ecosystem and the cooperative start-up space structure for strengthening start-up sustainability through cooperation between universities and local communities. The results of this study are expected to be used as useful basic data for Co-Space construction to build a regional start-up ecosystem in a trend emphasizing the importance of start-up space, which is a major factor affecting start-up companies.

Amplified Collaboration Environment(ACE) is a display-rich project room that enables distributed teams to intensively work together to solve a complex problem. This paper presents reviews of some most important shared workspace models in real-time collaboration systems. It then describes a set of iterative design studies of evaluation the shared workspace for ACEs. The study involved small groups of users in two ACEs performed a collaborative visualization and analysis task while varying the display technology configuration. The goal of this study was to enhance intensive collaborative work in ACEs. The results showed that the participants benefited from the ability to see others' work over the high-resolution shared workspace, which helped enhance group awareness and performance.

As an IETF standard protocol, WebDAV provides infrastructure for managing and authoring resources and supports asynchronous collaborative authoring on the Web. The CoSlide server is an extension of the Jakarta Slide WebDAV server, providing various workspaces and collaborative services through the WebDAV protocol. The CoSlide server supports workspaces for storing and sharing information of various users, and provides environment for effective collaborative authoring. Actual collaboration activities are performed through a collaboration client software which provides collaboration services along with the CoSlide server. In this paper, we describe the development of the CoSpace client which operates in association with the CoSlide server, presenting effective collaborative environment. The CoSpace client provides user interfaces for accessing and controlling the resources of each workspace on the CoSlide server. In particular, CoSpace provides the facility to launch an authoring application from its workspace view, automatic locking, and downloading the content to be edited, and resource movement using mouse drag & drop.

With development of 3D virtual space technology, diverse studies on 3D virtual space are being conducted because virtual space is being recognized as an appropriate technology for the field of urban and architectural design. However, while the process of urban and architectural design is done based on collaboration of various interested parties, there is lack of studies that support such collaboration. Communication within the virtual space must be provided for 3D virtual space to support collaboration, and a quick and direct technique of expressing one's intentions is required. sketch technique is effective. Ambiguous lines of sketch are extremely effective in that the range of thoughts in the idea stage can be broadened. However, such traditional sketch technique alone is difficult to support collaboration in 3D virtual space. That is because diverse shapes of 3D space require input of sketch. Accordingly in this study, sketch annotation that can effectively deliver intentions in 3D space was studied. Annotation technique using sketch-box was examined.

Jakarta Slide는 아파치 프로젝트 중의 하나로 개발된 WebDAV 서버로서 인터넷 통하여 다양한 콘텐츠의 비동기적인 협업 활동을 지원한다. 하지만 WebDAV 프로토콜은 사용자와 그룹을 위한 작업공간을 명시적으로 지원하지 않기 때문에, Jakarta Slide를 통하여 복잡한 협업을 수행하기는 매우 어렵다. CoSlide는 이러한 문제점을 개선하기 위하여 Jakarta Slide를 확장한 협업시스템으로서 다수의 사용자와 그룹을 위한 다양한 작업공간을 제공하여 효과적인 협업 환경을 제공한다. 협업시스템을 통하여 복잡한 협업을 보다 효과적으로 수행하기 위해서는 협업 참여자들 간에 실시간적인 통신이 원활이 이루어져야 할 필요성이 있다. 본 논문은 CoSlide 협업시스템에서 실시간 메시징을 지원하기 위한 CoJBother 메신저 클라이언트의 개발에 대하여 기술한다. 개발된 CoJBother는 협업시스템의 사용자와 그룹을 정의하기 위하여 개발된 Jabber 프로토콜을 사용하며, 또한 이를 지원하기 위하여 개발된 메신저 서버와 함께 동작한다. 사용자는 CoJBother를 통하여 협업시스템의 작업그룹에 참여하는 사용자들을 확인하고 자동적인 그룹채팅 기능을 사용함으로써 그룹 참여자들과 협업 수행을 위한 원활한 의사소통을 할 수 있다.

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.

인터넷이 발달함에 따라 인터넷 기반의 협업시스템을 이용하여 정보를 교환하고 협업을 수행하는 사용 자와 그룹이 급속히 증가하고 있다. 이러한 사용자들이 급속히 증가함에 따라 사용자들의 다양한 작업 환 경을 고려한 개인화된 협업서비스가 제공되는 것이 바람직하지만 현재의 협업시스템들은 이러한 서비스를 제공하지 않아서 효과적인 협업 환경을 제공하기 어렵다. 본 논문은 협업시스템을 이용하여 다양한 사용자들의 협업 수행을 지원하는 CoPortlet의 개발에 대하여 기술한다. CoPortlet 은 포탈에 포함되는 포틀릿 컴포넌트로서 협업시스템 서버에서 제공하는 다양한 가상 공간을 지원하며, 각 가상공간의 자원을 제어하는 기능들을 제공한다. CoPortlet은 Struts 프레임워크를 바탕으로 설계하였으며, WebDAV 프로토콜을 이용하여 협업시스템과 상호 동작한다. 사용자는 여러 포틀릿과 함께 CoPortlet으로 구성되는 포탈을 이용하여 자신의 작업 환경을 고려한 맞춤형 인터페이스를 구성하고 효과적으로 협업을 수행할 수 있다.
