As good example of potential application-specific requirement, (m,k)-firm real-time streams have been recently introduced to deliver multimedia data efficiently in wireless sensor networks. In addition to stream model, communication protocols to meet specific (m,k)-firm real-time streams have been newly developed or extended from existing protocols. However, since the existing schemes for an (m,k)-firm stream have been proposed under typical flat architecture, the scalability problem remains unsolved when the number of real-time flows increases in the networks. To solve this problem, in this paper, we propose a new clustering scheme for an (m,k)-firm stream. The two different clustering algorithms are performed according to either the (m,k)-firm requirement or the deadline. Simulation results are presented to demonstrate the suitability of the proposed scheme under hierarchical architecture by showing that its performance is acceptable irrespective of the increase in the number of flows.

This paper is a longitudinal study, comparing survey results between two time periods. A previous survey was conducted in 1999. After 10 years of the first survey, the second survey was conducted while utilizing the same questionnaire. A list of membership of Korea Institute of Heallthcare Architecture was used as a sampling frame. At the first survey in 1999, questionnaires of 27.3 percentage were returned, and 15.5 percentage in the 2008 survey. Healthcare design is one of the highly specialized design types in architecture. In addition, it is demanded highly specialized knowledge to solve healthcare design problems. As a professional service firm(PSF), architectural firm utilizes knowledge assets to provide design service to clients. Specialized knowledge in question is one of the core assets of PSF. The knowledge generates competitive advantages and plays an effective role as a marketing tool for PSF. However, empirical studies dealing with the knowledge characteristics of specialized design(healthcare) firms were hardly found. Thus, this study aims to trace the professional architects' perception of knowledge demands for task performance and architectural knowledge assets. The results can be used as a reference when a specialized firm in healthcare design initiates to build knowledge assets in it.

The purpose of this paper is to analyze the organizational design and management of product development in creating new product architecture by an established firm. For the purpose, the paper put up the organizational design in the process of PDA(Personal Digital Assistant) development of Sharp and Casio which were Japanese major PDA firms in 1990s. PDA is the product born through architectural change from Electronic Organizer. Prior research on the product architecture change and organizational adaptation emphasized that an established firm is difficult to adapt to new product architecture due to the restriction of prior technology or organizational inertia. For overcoming these problems and successful development of new product architecture, organizational design and management in the process of product development becomes essential. In case of Sharp, corporate development project team had been used to overcome the restrictions from architectural knowledge accumulated through previous product. After launching first new PDA by corporate development project team, Sharp created a new division and pushed an evolution of PDA, when new PDA market start to grow up rapidly toward a major market segmentation. As a result, Sharp was able to build up stable PDA project trajectory. However, Casio was late for three years in launching of new PDA architecture because previous division charging of Electronic Organizer tried to develop first new PDA. Casio's PDA development was prohibited by engineers of previous division because new PDA architecture was inferior on user interface and display definition. That is, Casio's first PDA development was restricted by architectural knowledge of previous product.

In the past, safety management has been carried out mainly by constructors, but now, participants of all construction projects such as clients, designers, constructors, and construction managers are being changed to perform safety management together. Among them, the design safety review, which examines whether the client has secured the design safety at the design stage, has been implemented since May 19, 2016, but it has not been properly implemented. Therefore, this study analyzed perception level and problems of D.F.S in architecture design firms and suggested the solutions.
