This paper proposes the distributed virtual environment framework for collaboration between heterogeneous platforms. The proposed system consists of Client, Content Server(CS), and Reflector Server(RS). The Client is composed of VR library(VRL), Interaction Manager(IM), Distributed Interaction Manager(DIM), and Network Interface(NI). The proposed Client structure can support various display environments. The XML-based IM and DIM lets the users define and add the interactions. The proposed Server structure synchronizes the distributed interaction between heterogeneous platforms and provides transparency to the users. Therefore, the proposed framework enables the users to implement virtual collaboration environment for their tasks. Moreover, it can also be used for research and development activities between a large number of the remote users. The usefulness of the framework was verified by applying it to the virtual heritage tour system.

Advance in Internet technology has changed traditional production planning and control methods. In particular, collaborations between participants in supply chains are being increasingly addressed in industry for enhancing chain-wide productivity. A representative paradigm that emphasizes collaboration in production planning and control is CPFR(Collaborative Planning, Forecasting and Replenishment). In this paper, we present a multi-agent system architecture that supports the collaborations specified in CPFR. The multi-agent system architecture consists of event manager, data view agent, business rule agent, and collaboration agent. The collaboration agent systematically controls negotiation between supplier and buyer with the aid of collaboration protocol and blackboard. The multi-agent system has been implemented with EJB(Enterprise Java Beans).

This paper explains an error process for multimedia collaboration works with session management running on vehicle network environment. This system consists of an FDA and FRA. FDA is an agent that detects an error by hooking techniques for multimedia system based on vehicle network environment with session management. FRA is a system that is suitable for recovering software error for multimedia system with session management based on vehicle network environment. This paper describes only FRA. When multiple local sessions is opened, each local session manager sends information of participant to global session manager and take current information about session of processing in network.

In this study, we proposed duty executions to confine a robot in a specific place with multiple robots. The proposed method involved the use of a role classifier for assigning labor roles, behavior selector for each robot, and a collaboration manager for handling complex situations. Further, we verified the validity of the proposed method by performing simulations to confine a robot in the specific location by using multiple robots.

Although the requirement of enterprise security implementation has been raised, a few research on security collaboration, which is one of the methods for enterprise security has been performed. This paper approached information security from the collaboration-centric perspective and propose critical success factors for security collaboration. In this study, a model of security collaboration, which includes coordination and cooperation activities was devised. Based on the previous research on organizational collaboration literature, the eight success factors for collaboration were deduced and examined the significance of the eight factors using the PLS-SEM statistical method with data of 106 samples who are security and IT professionals who have worked for more than 7 years. The result of the hypothesis test supported that trust, expertise motivation, collaboration performance criteria, top manager support and collaboration tools are the prominent factors of security collaboration.

그 어느 때 보다 한국경제에서 사회경제적시스템의 성공적인 안착이 필요 한 시대이며, 해외 선진사례에서 보듯이 최근 사회경제적시스템에서 고용창출, 소상공인 경제적 활로 개척 등 소상공인의 협동조합의 역할과 중요성이 점점 커지고 있는 실정이다. 이러한 사회경제적망에서 소상공인협동조합의 자원을 위한 중소벤처기업부/소상공인시장진흥공단은 전국 8대 권역(2분소)에 소상공인협동조합을 위한 협업아카데미를 운영 중에 있다. 각 권역별 협업아카데미에서는 컨설팅, 교육, 네트워킹 등 공통 조합지원 프로그램으로 운영하고 있으나, 소상공인시장진흥공단의 정량/정성적 평가에 따르면 각 아카데미별 운영 결과는 상이하게 나타나고 있다. 이는 협업아카데미 운영인력(매니저)의 자질과 업무 수행역량에 따른 상이한 결과로 판단하고 있다. 이에 협업아카데미 운영 인력의 업무적 필요 역량에 관한 연구를 통해 운영인력(매니저)수급과 인력운영에 관한 기준점을 설정하고 효과적이고 생산적인 소상공인협동조합 지원사업을 수행함에 있어 유용한 자료를 제공하고자 한다.

WebDAV is a protocol to support collaboration among the workers in geographically distant locations through the Internet. WebDAV extends the web communication protocol HTTP/1.1 to provide a standard infrastructure for supporting asynchronous collaboration for various contents across the Internet. To provide the WebDAV functionality in legacy applications such as web-based collaborative systems or document management systems, those systems need to be implemented additionally to handle the WebDAV methods and headers information. In this paper, we developed an Apache-based WebDAV server, named DAVinci(WebDAV Is New Collaborative web-authoring Innovation)which supports the WebDAV specification. DAVinci was implemented as a form of service provider on a mod_dav Apache module. Mod_day, which is an Apache module, is an open source module to provide WebDAV capabilities in an Apache web server. We used a file system for storing resources and the PostgreSQL database for their properties. In addition, the system provides a consistency manager to guarantee that both resources and properties are maintained without inconsistency between resources and their properties.

Background: Adolescent mothers may find the transition to motherhood to be Aim: The aim of this study was to investigate the viewpoints of nurse managers and directors of nursing services in community hospitals regarding the essential competencies of head nurses. Methods: A qualitative descriptive design was used to investigate the perspective of nurse managers and directors of nursing services about essential competencies of nurse managers in community hospitals. A total of ten participants (four directors of nursing services and six nurse managers) were interviewed. Findings: Nurse managers and directors of nursing services identified leadership, management, communication, professional ethics, and policy and healthcare environment as the essential competencies for their positions in community hospitals. Conclusions: These findings can be used by executives of community hospitals and nursing institutes to plan for competency development for nurse managers. They should be included in nursing administration programs.

본 연구에서는 웹 기반 멀티미디어 협력 작업 환경에서의 오류 관리기에 대해서 기술한다. 웹 기반 멀티미디어 협력 작업 환경은 멀티미디어 협력 작업에 웹의 동기화 기술을 확장한 웹노트, 즉 복제형 구조에 기반한 응용 공유의 동작 원리를 이용하여 동기화를 수행할 수 있는 환경을 의미한다. 오류 관리기의 기능에는 오류 검출과 복구가 있다. 웹 상에서의 세션 유지와 복원을 위하여 웹 세션과 직접 연관된 프로세서만을 주기적으로 폴링(polling)하여 오류 감지를 수행하고 복구를 위하여 복원이 가능한 경우에는 단순 재실행 방법을 사용한다.
