The purpose of this study was to investigate service quality of department stores located in Daegu and to examine the effects of service quality on customer satisfaction and store patronage. Data(N=285) were analyzed, using factor analysis, 1-test, ANOVA and regression analysis. The results suggest that service quality was divided into 3 dimensions (reliability, tangibles, empathy) and that service quality enhanced customer satisfaction and store patronage. Specifically, tangibles had a positive effect on customer satisfaction, and reliability had a positive effect on store patronage. Also, personal characteristics were related to service quality, customer satisfaction and store patronage. For instance, male customers evaluated tangibles of service quality more positively than female customers. The married evaluated service quality, customer satisfaction and store patronage more positively than the single. While people aged above 36 yews evaluated reliability and empathy of service quality more positively than people aged below 35 years, people in their 20s evaluated tangibles more positively than people in their 30s. People in a higher income bracket (i. e., \301,000,000- \400,000,000) evaluated reliability and empathy of service quality and store patronage most positively, while people in a lower bracket (i. e., below \200,000,000) evaluated most negatively.

In this paper, we propose an optimization method for obtaining beam curve which minimize the phase errors of Rotman lens. This method is based on idea that 3 path lengths from a beam port through equal phase points, which consist of the center point of array antenna and two points placed symmetrically or asymmetrically along array antenna, to the corresponding phase front are equal. According to this method, the optimal locations of beam ports can be obtained directly by finding each equal phase point set on array antenna to minimize the phase errors for each beam direction. Simulation results show that the proposed method is the most optimal and effective method for determining the beam curve of Rotman lens with low phase errors.

Recommendation systems are developed to overcome the problems of selection and to promote intention to use. In this study, we propose a recommendation system using adjacency data according to user's behavior over time. For this, the product adjacencies are identified from the adjacency matrix based on graph theory. This research finds that there is a trend in the users' behavior over time though product adjacency fluctuates over time. The system is tested on its usability. The tests show that implementing this recommendation system increases users' intention to purchase and reduces the search time.

Retail space itself could be one of the marketing strategies, through creating space, and communicating brand identity. Especially for innovative products, such as mobile technology products, store is not just to sell products but to provide experiences so that users can fudge usefulness of products and reduce uncertainties to adopt the products. The purpose of this study is to investigate how environmental features and physical artifacts contribute to promote experiences of innovative products in stores and how physical environment help to establish brand identity. For this study, site visits, observation, and literature review were conducted. For case studies, three retail spaces (Apple, Iriver, Sony) and one service space(TTL) were selected. Compared to the service space, three retail spaces have more transparent and open store front design characteristics. For the experiences of shoppers, products displayed in a radial shape, round shape, column shape, and around peripherals of the stores. A service oriented space, TTL zone is differentiated from three retail spaces in terms of layout, store front design, and experience areas. Compared to the traditional stores selling innovative products, the case stores showed more warm atmosphere using various shape, wood materials, lighting fixtures and furniture.

In case of fire and explosion which resulted from LP gas release of LPG vessel retail store, the populated area such as apartment complex is supposed to be damaged either partially or totally. To estimate the damage of LP gas explosion, we conducted quantitative risk analysis procedure as has been recommended by AIChE/CCPS. For incident scenario selection, event tree analysis was proposed. TNT equivalent method, SAFER Trace v.8.0 and probit model were also used for consequence analysis. The various methods and analyses which were performed in this study are presented with the effect zones in the layout.

Using Snell's Law without approximation, we analyzed focal points for parallel rays incident upon the cornea of a human eye. To calculate a ray's incident angle versus incident height for focusing on the same point, we used the ray reverse tracing method. We derived the theoretical conditions for an aspherical lens to remove the spherical aberration caused by a human eye. In this research, we held the rear surface of the lens to be spherical, for simple calculation, and calculated the lens curvature of the front surface to design an aspherical surface.
