In a competitive environment, selecting and effectively pursing the right information system investments can be a key factor in sustaining corporate viability and prosperity. This study applies quality function deployment(QFD) to the determination of information system development priority. The intent of QFD is to incorporate the needs of a customer through the various stages of product planning and manufacturing into a final product. The basic idea of our study is to translate the core competence and the competitive environment into the business strategy, and the critical success factors, and subsequently into information system development priority. Our method is applied to a motor company for the determination of the information system development priority. The company case is illustrated step by step with real data of the company and motor market.

Among the various possible factors affecting the Minority Carrier Life Time (MCLT) of the mc-Si crystal, dislocations formed during the cooling period after solidification were found to be a major element. It was confirmed that other defects such as grain boundary or twin boundary were not determinative defects affecting the MCLT because most of these defects seemed to be formed during the solidification period. With a measurement of total thickness variation (TTV) and bow of the silicon wafers, it was found that residual stress remaining in the mc-Si crystal might be another major factor affecting the MCLT. Thus, it is expected that better quality of mc-Si can be grown when the cooling process right after solidification is carried out as slow as possible.

It is a quite quality concerning to control temperature of single crystalline growth as it does when you get most of heat treating products. It is also important factor to control temperature when you make the $Al_{2}O_3$(single crystalline) used to artificial jewels. glass of watches. heat resistant transparent glasses. Thus. it is a major interest to get the proper temperature in accordance with the time process while you are making mixture of oxygen and hydrogen to have the right temperature. In this paper. we will study of electrical valve positioning system for the gas mixture to improve the quality of products.

Today, rapid development and timeliness of introducing a new product be- comes a more influencing factor of determing its competitive power due to a shortened product cycle, while rapid improvement of manufacturing technology makes product design and manufacturing fuse together. This implies that prod- uct usability evaluation and improvement starts right from its design phase, resulting in less development time and cost. To make this possible, proper as- sessment of human reach is one of essential functions for ergonomic product us- ability evaluation, specifically in the platform of computer-aided ergonomic evaluation models or any CAD system with a built-in man model. In this study, an analytic reach prediction algorithm ensuring the posture that human naturally takes, is presented by employing the methods developed for robot kinematics. Among robot kinematic methods for solving the multi-link system, the resolved motion method was found to be effective to solve human reach as a redundant manipulator model. Also, the joint range availability was used as a performance fonction to guarantee human naturalness. The result is expected to be directly applicable to product usability evaluations.

This study aims to examine the Visitor's selection attributes and types of preference regarding Rural Theme Village, and gather useful information for establishing differentiated marketing strategies suitable for market segments by the Visitor's selection attributes. In addition, it will contribute to securing competitiveness in providing Visitors with better service by extracting differentiating factors of Rural Theme Villages, and exploring the right direction of Rural Tourism. For the empirical analysis, the attributes were extracted based on the preliminary studies, and a survey was conducted among Visitors and users of Rural Theme Village to examine such factors as importance of selection attributes status, motives of using such Rural Theme Villages, demographic characteristics, and general features of the Rural Theme Villages.

Usability has become a primary factor in determining the acceptability and consequent success of consumer product. It is common that the product usability is evaluated by objective performance measures and/or subjective user preference measures. This study is concerned with objective evaluation of the product usability using 3-dimensional motion analysis. We evaluated car-audio position using 3-dimensional motion analysis. The parameters investigated in this experiment were height of car-audio, left-right angle, and front-end angle. The experimental results showed that the usability evaluation method using motion analysis was consistent with user's subjective assessment. This objective method can be applied to not only car-audio position evaluation but also various consumer products'usability evaluation.
