The majority of small/medium sized shipbuilders in Korea is poor in capital and then, should be restructured as an efficient production system with low investment. Due to considering this situation, the cooperative work system is proposed, in this study, as more effective production system for small/medium sized shipbuilder The cooperative work system Is the production system that many small/medium sized shipbuilders in a group jointly share the common facilities except minimum equipments and have managerial cooperation such as joint purchase of raw materials. The efficiency of cooperative work system is proved from economic and technical point of view with the case study of FRP shipbuilders of Sapjin industrial complex located at Mokpo area.

In this paper, a prototype of cooperative work model for multi-robots system is introduced and the evolutionary approach is applied to generate the motions for the cooperative works of multi-robots system using genetic algorithm. The cooperative tasks can be performed by a humanoid robot and a mobile robot to deliver objects from shelves. Generation of the humanoid motions such as pick up, rotation, and place operation for the cooperative works are evolved. Modeling and computer simulation for the cooperative robots system are executed in Webots environments. Experimental results show the feasible and reasonable solutions for humanoid cooperative tasks are obtained.

To support cooperative work in various scenes by computer systems, functions of sharing personalization, observation and control are needed. Especially, in advanced cooperative work, people have various position so that sometimes one person needs to restrict behavior of another. In this paper, we describe representation of access restriction of hypermedia system, which is framework of CSCW(Computer-Supported Cooperative Works) system we developed and propose a way to go on working cooperatively with people, restricting others.

The cooperative production system was proposed as an efficient production system to reduce the ship construction cost and to enhance the competitiveness for small/medium sized shipbuilder in the previous paper. In viewpoint of cooperative production system, the specialization of the FRP ship sizes has already been accomplished to reduce the number of the hull molds by FRP shipbuilders of the Sapjin industrial complex located in Mokpo area in 2003. There also exist lots of effective methods, as a cooperative production system, to cut down the construction cost. In this study, an effective production system in connection with the super structure and outfitting members is proposed such as the standardization of those items and specialized company which intensively produces the super structure and outfitting members at the collectivization area for cooperative work.

For the efficient co-authoring of multimedia documents in a distributed systems environment, the cooperative-work management systems that can not only allow the sharing of distributed resources but also facilitate the authors' interaction, are needed. In this paper, we present a cooperative-work management system with hybrid architecture, called CW-MAN, in which the information on shared objects and co-authoring management is stored in a dedicated computer system but the shared objects distributed all over the local computer systems. The main management functions provided by the CW-MAN are those for shared objects, session, and telepointing. The shared-object use them exclusively. The session managements allows authors to dynamically create, update, and destroy sessions. Lastly, the telepointing management allows local pointing events to be synchronously presented to remote systems.

This paper presents a haptic display of a cooperative work between the networked multiple users. Excluding the possibility of large timedelay among the users, it is presented the way of configuring individual haptic display systems including the computation of interaction forces, joint driving forces of haptic devices and simulation of the virtual objects. A haptic display system is developed consisting of two haptic display devices operated by two remote users and experimental results to show the validity of the proposed method are also presented.

In this paper, we propose an extended reality-based simultaneous multi presence system in a process of remote cooperative work. The proposed system generates a ring-shaped invisible screen which surrounds a user, and it provides position and manipulation of remote workspace and personal workspace. With the proposed system, the user easily navigates the several workspace for the remote collaboration or he/she selects a specific space for immersion. The proposed system also provides manipulation of personal workspace for the user during the remote cooperative work. We conducted a user study to prove effectiveness of the proposed system. According to the results, the proposed system increased understanding spatial information and usage of time during the remote cooperative work.

2012년 12월 협동조합기본법이 시행된 이래, 2015년 6월 현재 전국적으로 약 7,300여개의 협동조합이 설립되어 조합원들의 유기적인 공동활동을 통해 공동사업을 수행하고 있다. 소상공인협동조합, 사회적협동조합 등 다양한 형태의 협동조합은 자신들의 공동목적을 달성하기 위한 요소로 업무정보 공유에 기반한 협업이 필수적이라고 인식하고 있다. 기획재정부의 분류에 따르면 21개의 업종으로 다양한 산업군에 걸쳐 협동조합은 하나의 기업처럼 사업활동을 하고 있다. 하지만, 일반기업과는 달리 협동조합은 수직적인 경영구조가 아닌 조합원들 간의 수평적 경영조직을 갖는다. 본 논문에서는 공동사업 수행과 공동이익 창출이라는 협동조합의 특수한 사업모델과 전국에 산발적으로 분산되어 있는 조합원들 간의 공동업무 활동을 위한 협업 시스템을 제안한다.

This paper describes the modeling of work environment for the extraction of abstract operation rules for cooperative work with multiple agent. We propose the modeling method using a potential field. In the method, it is applied to a box pushing problem, which is to move a box from a start to a goal b multiple agent. The agents follow the potential value when they move and work in the work environment. The work environment is represented as the grid space. The potential field is generated by Genetic Algorithm(GA) for each agent. GA explores the positions of a potential peak value in the grid space, and then the potential value stretching in the grid space is spread by a potential diffusion function in each grid. However it is difficult to explore suitable setting using hand coding of the position of peak potential value. Thus, we use an evlolutionary computation way because it is possible to explore the large search space. So we make experiments the environment modeling using the proposed method and verify the performance of the exploration by GA. And we classify some types from acquired the environment model and extract the abstract operation rule, As results, we find out some types of the environment models and operation rules by the observation, and the performance of GA exploration is almost same as the hand coding set because these are nearly same performance on the evaluation of the consumption of agent's energy and the work step from point to the goal point.
