In the trend of globalization and location transfer of existing production bases is still characterized by an extremely unstable status between different countries and different regions. The results are negative impacts on cost, quality and speed of project implementation, especially automobile industry which is one of the most complex manufacturing sectors. In order to overcome problems from Global Standardization of Production Line and its Localization, it is highly required comprehensive coordination among design of production equipment, production technology, space and interfaces. It is necessary to set up standard of production equipment and building for parallel progress, in order to complete production line in shortest time for launching product. In addition, this standard should keep flexibility with consideration of local situation which means "Glocalization."

Power conversion systems used in large gas turbine power plant can be divided into two main part. Because of the initial start-up characteristic of the gas turbine combustor, the gas turbine must be accelerated by starting device(LCI : Load Commutated Inverter) up to 10%~20% of rated speed to ignite it. In addition, the ECS(Excitation Control system) is used to control the rotor field current and reactive power in grid-connected synchronous generator. These two large power conversion systems are located in the same space(container) because of coordination control. Recently, many manufactures develop high speed controller based on function block available in the LCI and ECS with the newest power semiconductor. We also developed high speed controller based on function block to be using these two system and it meets the international standard IEC61131 as using real-time OS(VxWorks) and ISaGRAF. In order to install easily these systems at power plant, main controller, special module and IO module are used with high speed communication line other than electric wire line. Before initial product is installed on the site, prototype is produced and tests are conducted for it. The performance results of Integrated controller and application program(SFC, ECS) were described in this paper. The test results will be considered as the important resources for the application in future.

Digital Media have been advanced and disseminated at the same time around the world. Digital contents have been evolved while Product Technology and Process Technology of 3D Digital Animation and On-line game have completed the innovative developments. First of all, several problems can be occurred when product technology can not lead the evolvement of digital contents. To accomplish the evolvement of both product technology and process technology of digital contents, the whole production system and process system must be modulized. Modulization of system can be completed by the consistent and stable integration of platform. Modulization of production system can bring out the modulization of product technology and then the modulization of technology can speed up the commercialization and market test.

As new luxury brands are becoming more popular, recent new luxury consumers are showing different tendencies of consumption. The purpose of this study is to investigates the specific bond between the product benefits for new luxury fashion brand and the consumer-brand relationship. Specifically this study conceptualizes the dual path which leads to brand loyalty and brand commitment. 300 data from on-line survey were collected from middle class women who had trading up needs and respondents were asked to select their favorable new luxury fashion brand. As a result of an exploratory factor analysis to identify the structural dimensions of product benefit for new luxury brand groups, four factors were extracted; psychological/emotional benefits, social/symbolic benefits, self-expressive benefits, and product functional benefit. Additional results show that brand attitude had more positive effect on brand loyalty and brand attachment had more positive effect on brand commitment. The findings of this study contribute to provide practical implication on market segmentation for new luxury brands.

This paper is to identify whether the mechanism of the real market as an off-line market developed from the transaction cost theory from previous research is applied to on-line market, such as usiness to Business e-marketplaces. With three factors(parties, product, environments) selected from previous research, four cases picked up from all B2B e-marketplace sites as of April 2007, in the view of Business to Business Matrix which presented by Kaplan & Sawhney(2000), were studied. They were accompanied by interview with CEO and team manager, and they explained their business and revenue model of the company. From the interview, the relation between three factors and usiness to Business e-marketplace was observed by taking sub-factors into consideration; parties -asset specificity, information asymmetry, product factors - standardization, price stability, and environments factors - competition, market uncertainty. The implications of this study are to analyze the relation of the transaction theory in offline and online. Also, this is the first study that analyzed it. In the future, another research based on this research will be studied.

Since Chrysler Motor Co. had experienced the digital development system in the beginning of 1990's, most of leading automobile companies are trying to apply a digital information system for their own business process reengineering based upon concurrent engineering system from product planning phase. This is called as virtual DMU(Digital Mock-Up) system instead of the traditional PMU(Physical Mock-Up) system. By using the virtual prototype, all of the design requirements and system specifications can be checked, changed and optimized more quickly and more efficiently. This paper consists of five chapters for the DMU information system. In the 1$^{st}$ chapter, the principle of digital design system is suggested by using four basic modules such as product design module, process design module, manufacturing system design module and central control module. The basic scheme of DMU is introduced with the benefits of application in the chapter 2. In the chapter 3, a digital design process of new car development is explained with the detailed DMU design and design review processes. In the chapter 4, the practical DMU manufacturing techniques and applications are introduced as CAD/CAM analyses, DPA(Digital Pre-Assembly)reviews for development, production, operation and maintenance phases, digital tolerance analyses and digital factory analyses for assembling line simulation, automated robot welding processes, production jig ＆ fixtures and painting process simulation. Finally, the activities of digital design support; CAS-styling, CAE-engineering and CAT-testing are summarized for design optimization in the chapter 5. As today's automobile manufactures and related business organizations are struggling to compete in the global marketplace, they are concentrating on efficient use of DMU information system to reduce the new car development cost, to have shorten the delivery schedule and to improve product design quality. To meet the demand of those automobile industries on digital information systems, the CALS(Computer aided Acquisition and Logistics Support) and EC(Electronic Commerce)initiative has been focused as a dominant philosophy in defense ＆ commercial industries, specially automobile industries.s.

Tiny camera module using in modern cellular phone requires precise assembly processes. Higher camera resolution and more functions such as zoom lens make the number of camera parts bigger. As market grows rapidly, automatic assembly process is required. However, diverse product line and short life cycle make it difficult. To attack this, a flexible and expandable lens assembly system is proposed. For the fast manufacturing line formation, modular concept is adopted. Also each module is designed to have intelligence to save system formation time. The assembly system is built up on the standard flat-form which provides vibration free base, air and electric supply, controllers, etc. Futhermore, the assembly cell has the capability of handling tiny, thin, or transparent parts which are very difficult to align with vision.
