The paper aims to identify major research issues and basic framework of computer supported collaborative work in design through reviewing recent changes in product development which is getting more integrated, collaborative and computerized. At first the importance of collaborative work in design is discussed throughout the development of design process: from blackbox approach in vernacular design to recent Nigel Cross' es Hybrid model. Then Concurrent Engineering and Quality Function Depolyment are reviewed for showing recent phenomena of integration and collaboration in the process of product development. Computer-aided product development is demonstrated with the case of Blackboard system and Computergenerated form development. In order to outline the fundamental approach for computer-supported collaborative work in design, structures and processes of some related projects are introduced. Finally, based on the findings, some research issues for further rJevelopment are proposed.

In the current mobile environment that is indispensable to our everyday lives, various forms of new business models are created including personalized services such as Google's "Google NOW" and Apple's "Siri". These services would not have been possible without technologies on the effective integration of various services and models. The requirements for effective integration of services include, 1) the efficient data sharing among multiple services, 2) the data-driven asynchronous execution of services, and 3) the simple extensible interaction method for the services. In this paper, we propose a mobile service architecture that utilizes the blackboard architecture to satisfy the aforementioned requirements to enable effective integration of various services, sharing and management of data between services, and asynchronous execution of services.

In this paper, we propose a novel sharing method ordering the events occurring between users collaborated with the common telecomputing environment. We realize the sharing method with multimedia data to improve the coworking effect using teleprocessing network. This sharing method advances the efficiency of communicating projects such as remote education, tele-conference, and co-authoring of multimedia contents by offering conveniences of presentation, group authoring, common management, and transient event productions of the users. As for the conventional sharing white board system, all the multimedia contents segments should be authored by the exclusive program, and we cannot use any existing contents or program. Moreover we suffer from the problem that ordering error occurs in the teleprocessing operation because we do not have any line-up technology for the input ordering of commands. Therefore we develop a method of retrieving input and output events from the windows system and the message hooking technology which transmits between programs in the operating system In addition, we realize the allocation technology of the processing results for all sharing users of the distributed computing environment without any error. Our sharing technology should contribute to improve the face-to-face coworking efficiency for multimedia contents authoring, common blackboard system in the area of remote educations, and presentation display in visual conference.
