기업들의 글로벌화가 빠르게 진행되고 고객 밀착형 업무가 늘어나게 됨에 따라 모바일 오피스에 대한 기업의 니즈가 빠르게 증가했다. 이러한 비즈니스 요건을 해결하기 위해서는 기업 근무자가 다른 시간, 다른 장소에서도 효과적인 업무 협업과 커뮤니케이션을 수행할 수 있는 서비스와 시스템 환경이 필요하다. 실시간 비즈니스 협업 시스템은 기업 근무자들이 스마트 폰과 웹을 통해서 실시간으로 업무 협업을 할 수 있도록 상호 서비스 호출이 가능한 시스템을 구현 하였다.

This study was carried out to investigate members' affiliation motive to Forest Management Cooperative which is the main managemental body of the private forests and management problems of the organization to find out a solution of the problems and set active promotion plan. The questionnaire about the management of the cooperatives was done by interviewing the members at Seoha Inboh Forest Management Cooperative in Ulsan-gun, Kyongsangnam-do and Sechong Forest Management Cooperative in Chinan-gun, Chollabuk-do from July to August in 1993. Twenty interviewees were selected in the order of their business quantity on the forest from the members who reside in their villages. Integrated matters such as were members' affiliation motive, benefit after their affiliation, management system, incorporation of the organization and other issues concerning to managemental plans questioned. During the survey period, other data about management of the cooperatives were collected from the related organizations and opinions of every president of nine cooperatives in the investigated regions. The majority of the members agreed that the cooperative is an independent forest organization and evaluated the Training and Extension Service Center high. However, their participations in the cooperative such as forest technical training and cooperative forest management were low since they have not earned any income from their forest management.

The development of collaboration among information systems in accordance with changes in enterprises' business environment brings about the problems of duplication of the existing business services and increase in costs of maintenance. Accordingly, Web service has been suggested as the standard of distributed computing to prevent the duplication of services within the same business domain and to attain the services that are already being utilized. But since the data needed for Web services are not standardized, it is difficult for the users to find services that meet diverse business purposes. In this paper, we construct an ontology-based collaboration system for service interoperability. The ontology can support fusion service by finding services which are existed interdependently under the distributed environment for collaboration processing. The role of the collaborative system includes development, registration and call of services based on ontology. A local systems request collaboration support through the service profile. Collaborative system supports the development of service using the service profiles, represents the semantic association between real data through system ontology, and infers relationship between instances contained in the services. Based on this, we applied the travel booking services for collaboration system. As a result, service can be managed effectively preventing collision in collaborative system, and we verify that the mapping between system is reduced.

Applying maintenance simulation using virtual mockup in product design phase enables maintainability test before prototyping physical products, and it is expected to reduce product development costs. The simulation results can be reused as contents of service manuals and RAM (Reliability, Availability, Maintainability) analysis data. Maintenance simulation should provide realistic representation of physical property of virtual product, assembly relation between parts and manipulation process to verify feasibility of product design. The simulation system should be extended to collaborative virtual environment to perform collaborative maintenance procedures. In this paper, the three layered system architecture and the physics based collaborative interaction technique are proposed to extend current maintenance simulation into collaborative virtual environment. The proposed system was implemented as ViMMS (Virtual Mockup Maintenance Simulation system), and compared with case study results of VADE (Virtual Assembly Design Environment). As a result, the ViMMS encompassed broader range of maintenance tasks by using physics based collaborative interaction technique.

Team-based programming methods are widely applied to solve various difficulties that pre-service teachers experience in the programming lessons. To prepare effective collaboration strategies necessary for them, it is necessary to analyze various collaborative factors that affect learners' programming competencies. Therefore, in this article, a questionnaire survey was conducted by dividing learners' collaboration factors into individual and team competencies, and the relationship between learners' programming competencies was analyzed. As a result of the verification, the program design competency showed significant results in all elements of the learner's personal competency, team techniques such as data sharing skills necessary for collaboration, and team collaboration. It was analyzed that an individual's understanding of learning and team collaboration influenced the program implementation competency. In addition, the group with relatively high team technique showed significant differences in programming competence, interest, and satisfaction. Accordingly, by linking meaningful factors related to individual and team competencies according to the programming process, a collaborative strategy practically necessary for pre-service teachers was suggested.

It is important to control performance and a Sustainable Collaboration (SC) for the successful Supply Chain Management (SCM). This research developed a control model which analyzed SCM performances based on a Balanced Scorecard (ESC) and an SC using Support Vector Machine (SVM). 108 specialists of an SCM completed the questionnaires. We analyzed experimental data set using SVM. This research compared the forecasting accuracy of an SCMSC through four types of SVM kernels: (1) linear, (2) polynomial (3) Radial Basis Function (REF), and (4) sigmoid kernel (linear > RBF > Sigmoid > Polynomial). Then, this study compares the prediction performance of SVM linear kernel with Artificial Neural Network. (ANN). The research findings show that using SVM linear kernel to forecast an SCMSC is the most outstanding. Thus SVM linear kernel provides a promising alternative to an SC control level. A company which pursues an SCM can use the information of an SC in the SVM model.
