Vehicle dynamics control (VDC) has been a breakthrough and become a new terminology for the safety of a driver and improvement of vehicle handling. This paper examines the usefulness of a brake steer system (BSS), which uses differential brake forces for steering intervention in the context of VDC, In order to help the car to turn, a yaw moment can be achieved by altering the left/right and front/rear brake distribution. The steering function achieved through BSS can then be used to control lateral position in an unintended road departure system. An 8-DOF non-linear vehicle model including STI tire model will be validated using the equations of motion of the vehicle, and the non-linear vehicle dynamics. Since fuzzy logic can consider the nonlinear effect of vehicle modeling, fuzzy controller is designed to explore BSS feasibility, by modifying the brake distribution through the control of the yaw rate of the vehicle. The control strategies developed will be tested by simulation of a variety of situation; the possibility of VDC using BSS is verified in this paper.

This study analyzed consumers' online fashion shopping site usage by site type and analyzed how product information search and product purchase differ. In addition, by comparing and analyzing preference and selection factors of PC and mobile shopping, we tried to provide basic data of effective mobile commerce operation strategy according to expansion of mobile market in fashion industry. We surveyed the use of 6 types of online sites (portal site, open market, general shopping mall, social commerce shopping mall, brand shopping mall and non-brand shopping mall) to understand the usage of mobile shopping site for consumers' fashion products. Consumer survey subjects were 373 college students in their early 20s who had the most mobile shopping experiences. The questionnaire consisted of online fashion site usage items, internet and mobile fashion shopping preference (6 items), internet and mobile shopping choice behavior (10 items), and purchase intention (3 items) .Data were analyzed using SPSS 14.0 program. The high preference of portal sites, open market, social commerce, and non-brand shopping malls in shopping online fashion products is a result of the perceptual changes of major distribution channels and the trends of consumers' value consumption tendency. Therefore, it is necessary for fashion companies to actively cope with fashion product distribution competition with huge shopping sites of current online market by well understanding consumers' preference trends and factors of online sites.

Purpose - The objective of this study is to investigate the differences and interaction effects on the perceived financial risk between Korean and Thai consumers according to the types of product(utilitarian and hedonic) and price discount (bundle and 50%off). Research design, Data and Methodology - This paper sets up 6 research subjects. Data collection was carried out in Korea and Thailand. Data was made of 154 Korean and 147 Thai consumers. As for the independent variables for this study, consumer types are composed of Korean and Thai consumers, price discount types were bundle(1+1) and 50% off price, and product types consist of utilitarian and hedonic product. The dependent variable is perceived as a financial risk. Each question is measured as a Likert-type five-point scale. Results - According to the price discount and product type, perceived financial risk of Thai consumers is confirmed to be a larger one than that of Korean consumers. Also, there are interaction effects in the perceived financial risk. Conclusion - Our findings can be used as useful information for global retail markets as marketing strategies in future Korean enterprise through a comparative study on Korean and Thai consumers.

Price promotion of retailing stores is recognized as one of the most effective strategies for competitions. However, such a strategy causes traffic building, and consequently may lead to store confusion. Therefore, this research explores the effects of store confusion on customers of retailing store, and the methods to relieve the negative effects of store confusion. The specific purposes of this research are as follows. First, for the purpose of enlarging the scope of promotion research, this research is intended to prove that the increase of traffic building caused by promotion strategy has negative aspects. Second, it is assumed that trust and store familiarity are the important attributes affecting price promotion as well as relationship marketing. Third, this research is expected to provide managerial implications for the managers concerned with department stores because the subjects of experiment are customers of department store.

Purpose - This study's aims are to examine the effects of airline service quality on brand image, brand attitude and reuse intention and the mediating roles of brand image and brand attitude in the relationship between airline service quality and reuse intention. Research design, data and methodology - A total of 500 questionnaire copies were distributed and 474 were used for the empirical study after excluding some empirical inappropriate or unusable ones. To analyze the collected data, the SPSS/WIN 22.0 statistical package was used. Results - The result of analysis showed that all the intangible, tangible and human elements of the airline service quality positively influenced on brand image and brand attitude and did not directly influence on reuse intention. However, brand image and brand attitude played mediating roles in the relationship between all the service quality elements and reuse intention. Conclusions - This means that airlines need to develop service quality, which is differentiated and provides special feelings for customers and work out improvement strategies for positive brand images and attitudes, since customers choose and reuse airlines, based on brand images and attitudes, which are perceived and formed through the experience of airline service quality and word of mouth.

Purpose - Pricing strategy is a very effective marketing activity and has a significant impact on consumer purchasing decisions. Numerous studies have investigated the effects of various pricing strategies. However, tensile price claims have received little attention in the literature. It is thus necessary to investigate how different forms of tensile price claims affect consumer response. This study uses the consumer self-confidence level as a moderator of consumer behavior. Research Research design, data, and methodology - This study investigates the effect of four different tensile price claims (i.e., maximum discount, minimum discount, average discount, and range discount advertisements) on consumers' perceived savings. A survey was conducted to collect data for testing hypotheses. Results - The results show that consumers with high levels of self-confidence perceive more savings for maximum discount advertisements than minimum discount advertisements, for range discount advertisements than average discount advertisements. On the other hand, consumers with low self-confidence feel more perceived savings for average discount advertisements than range discount advertisement. Conclusions - The results of this study provide a new insight into the effectiveness of tensile pricing based on consumer self-confidence levels, which may provide valuable theoretical and practical applications.
