3D Modeling Solution can reduce projecting error and also make possible to design visually, so that it can minimize human resources. On the other hand, it has defects of operating difficulties caused by too much complex function, thus it consequently prevent user from prompt handling. According to this paper, the developed party S/W will help that user can construct the parts easily, can let everybody use 3D modeling solution readily, and make fast development of new product. This software will carry out prompt development of new product and derive satisfaction of customers from high quality. Also, saving time and expense naturally raise competitive power in consequence.

PAV is considered to improve quality of life and standards of living, improvement of which was caused by automobile hundred years ago. Comparative economic efficiency of PAVs is measured to compare each PAV. Specification and sales price of the PAVs are open to the public. BlackFly, Transition and Aeromobil 3.0 have competitive power in flying range, purchasing cost, and operational cost. Lift & cruise configuration and vectored thrust configuration PAVs are designed by many companies nowadays, and BlackFly which can be considered to be lift & cruise configuration is one of the most efficient PAVs. High battery price does not help multi-copter shaped PAVs to have economic efficiency. Aerodynamic wing, eVTOL, and low sale price are needed for PAVs to ride a wave of public interest as a new personal mobility. Under the conditions, the PAV can fly at downtown and can be purchased by people at large. Popularization of PAV could follow in the 100 years old footsteps of automobile.

The hotel business should enhance a service quality in order to improve management skills and profits. However, when compared the size of foodservice industry and hotel, it is show that the hotel management systems are insufficient. In this respect, this study examines how the culture of hotel business affects to service quality. The results of the analysis are as follows. First, the culture of hotel business affects restaurant tendency. Consequently, the hotel, which is open-minded culture, copes with the external changes in a flexible manner. Second, the culture of hotel business affects hotel management skills. Good culture of the business creates the positive result toward the employees, customers, prime cost and inventory control. Third, hotel restaurant tendency affects to efficient hotel service quality and management performance. Fourth, change of hotel management skills brings difference of service quality and management performance. Good hotel management skills will be able to raise the competitive power between hotels. In the future, various empirical researches are continuously expected. By doing so, the result of the study helps to scholars and hotel managers.

In order to build up competitive power in construction market and to cope with international policy, Design-Build bidding is one of the viable bidding system, encouraging collaboration between design office and building construction firm. Design-Build is a promising delivery system to help expediting schedules, saving costs, and improving Quality. However, the problems of Design-Build project in the domestic construction industry are not to be able to take advantages of fast-tracking and value engineering process, because of the problems of inappropriate system and participants' inexperience. The purpose of this study is to suggest alternatives for Design-Build bidding of public sector in the domestic construction industry in the costs, quality and time aspect.

Purpose: We used a data analysis method to improve semiconductor manufacturing yield. We defined and optimized important factors and applied our findings to a real-world process. The semiconductor industry is very cost-competitive; our findings are useful. Methods: We collected data on 15 independent variables and one dependent variable (yield); we removed outliers and missing values. Using SPSS Modeler ver. 18.0, we analyzed the data both continuously and discretely and identified common factors. Results: We optimized two independent variables in terms of process conditions; yield improved. We used DS Leak software to model netting and Contact CD software to model meshes. DS Leak shows smaller the better characterisrics and Contact CD shows normal the best characteristics Conclusion: Various efforts have been made to improve semiconductor manufacturing yields, and many studies have created models or analyzed various characteristics. We not only defined important factors but also showed how to control processing to improve semiconductor yield.

The development of competitive new product is essential in competitiveness power of modern enterprises. The enterprises need to develop new products for its continuous growth. In this paper, a new product development process which reflect voice of customer in design of the product is suggested. Delighters in Kano's quality model are applied in primary design step. In the main design step, we analyze that whether Kano's primary satisfiers satisfy the customer needs which was found using Timko's customer satisfaction coefficient. It is shown that Kano's delighters and Timko's customer satisfaction coefficient are very effective in new product development.

Value Creation issue for customers is emerging from the college education. Most colleges are facing to cope with over-supplied education facility problems against reducing population to apply to enter universities/colleges. The best way to overcome those problems might be to implement the Customer Satisfaction Management Strategy as if they were private firms for making profit. The main purpose in this study is to provide guidelines for CS strategy with a private college. It is focused on designing research plans and searching CS index. The process of this study is as follows; - Introduced the value creation strategy for customers with private colleges. - Proposed the CS management which is very important for enhancing competitive power - Evaluate various models to measure service quality and CSI for college service. - Provided some guidelines to research design of CS according to 6 customer categories. - Proposed some methodologies to apply a service quality measurement model. - Suggested a revised model from SERVPERF to adapt with college customers satisfaction. The result from this study showed that Customer Satisfaction Management would be the most important strategy to cope with confronting difficulties for private college and the revised model from SERVPERF would be an alternative solution. Further study is essential to assure the suggested model is valuable for private colleges because empirical test has not completed yet.

Japanese restaurant owners seek to secure their competitive advantage by implementing a unique competition strategy that may overcome hostile environment. Brand power, aggressive expansion and the partnership strategy with other businesses may be suggested. The present study is to find out the competitive advantages of Japanese restaurants, to compare the importance and satisfaction by different customer factors of choices and then, to identify what kinds of factors affect customer satisfaction. Total 205 copies of questionnaire, out of 230 distributed, were used for analyses. Cronbarch's alpha coefficient of all 20 items was 0.911. In terms of importance, Cronbarch's alpha coefficients were 0.887(food), 0.796(menu), 0.851(employee), 0.815(service), and 0.730(physical environment). For satisfaction, the coefficients were 0.876(food), 0.860(menu), 0.880(employee), 0.851(service), 0.730(physical environment). In addition, the exploratory factor analysis showed an acceptable factor loading, supporting 20 items' validity. The result showed that customers' perceptions of the importance of Japanese restaurant service quality was higher than their level of satisfaction in general. In particular, IPA analysis revealed that food and service factors were well operated as located in the first quadrant. However, service factor located in the second quadrant was perceived to be important yet perceived as being satisfied poorly. So this study suggests that Japanese restaurant owners should concentrate on the attributes included in this quadrant to improve the quality of foodservice. Lastly, menu and physical environment factors were located in the third quadrant showing low level of importance and satisfaction. On the basic of the IPA analysis, Japanese restaurant owners should identify their strengths and weaknesses and draw up a plan to improve service quality and to maximize their profits.
