Among the various elements affecting a customer's evaluation of automobile quality, buzz, squeak and rattle (BSR) are considered to be major factors. In most vehicle manufacturers, the BSR problems are solved by find-fix method with the vehicle road test, mainly due to various excitation sources, complex generation mechanism and subjective response. The aim of this paper is to develop the integrated experimental method to systematically tackle the BSR problems in early stage of the vehicle development cycle by resolving these difficulties. To achieve this aim, the developed experimental method ought to include the following requirements: to find and fix the BSR problem for modules instead of a full vehicle in order to tackle the problem in the early stage of the vehicle development cycle; to develop the exciter system including the zig and road-input-signal reproducing algorithm; to automatically localize the source region of BSR; to develop sound quality index that can be used to assess the subjective responses to BSR. Also, the BSR sound quality indexes based on the Zwicker's sound quality parameters using a multiple regression analysis. The four sound metrics from Zwicker's sound quality parameter are computed for the signals recorded for eight BSR noise source regions localized by using the acoustic-field visualized results. Then, the jury test of BSR noise are performed for participants. On a basis of the computed sound metrics and jury test result, sound quality index is developed to represent the harsh of BSR noise. It is expected that the developed BSR detection system and sound quality indexes can be used to reduce the automotive interior BSR noise in terms of subjective levels as well as objective levels.

As the materials being used in children's clothing become diverse, the number of reported problems related to various aspects of washing and wearing is increasing. Many customers experience great dissatisfaction when using these children's garments due to their lack of professional knowledge in washing, fabric, and detergents. Thus, this paper focuses on various cases in which housewives have experienced product damage after washing their children's garments according the prescribed directions. Of particular interest is how the consumers respond to such damage in garments and how their experiences with garment damage affect the sellers of these garments. A total of 292 housewives with children less than 8 years old living in Seoul responded to our survey, out of which 83 reported to have suffered negative consequences. By analyzing the 83 responses, the following results were found: First, the problems reported by the housewives in regards to washing children's garments were mostly related to the durability or color change problems. Secondly, the most favored means of response to garment damage were 'complaining directly to the seller' (16.7%) and 'complaining at the customer service department of the manufacturer or seller' (13.5%). Thirdly, among the actions they requested to the seller/manufacturer, 'ask for an exchange' marked the highest. Lastly, respondents admitted that their experiences with garment damage as well as the attitude or response of the manufacturer/retailer to their complaints would influence their repurchase intention.

This study analyzes the variable consumer characteristics that influence the intention to use online product reviews. In online e-commerce, where purchases take place without consumers seeing the products in person, the product reviews left by other consumers who have already purchased the product are believed to be valuable information. However, when different consumers read the same product review, their responses to it may vary. This study analyzes the characteristics of consumers who utilize product reviews for their purchases. Consumer characteristics are categorized into personal information, personality, purchasing tendency, and experience related to product reviews. These factors are examined to see if they have direct or indirect effects on a consumer's intention to use product reviews when making online purchases. We surveyed a total of 240 consumers who had experience using e-commerce and knew about online product reviews. Once the data was collected, path analysis was conducted using the statistics tool AMOS. The study results reveal that consumers who are female, extroverted, and have higher price sensitivity think that product reviews left by others are useful, and that this "perceived usefulness" has a positive effect on the intention to use product reviews for making online purchasing decisions. In addition, consumers who are agreeable to others, have high brand sensitivity, and who have left numerous reviews themselves demonstrated the tendency to trust reviews left by others more. Thus, we conclude that this "perceived reliability" makes it more likely that a consumer will use product reviews when making online purchasing decisions. Future research can be done to develop this study further by analyzing whether providing online product reviews corresponding to the personal characteristics of consumers enhances the effect of product reviews on online purchasing decisions.

This paper examines whether the functions of eCRM solutions affect the site visit and purchase by customers. The functions of eCRM solutions are extracted and classified into three categories of c-marketing, e-sales, and e-service. E-marketing includes campaign/event marketing, e-mail marketing, and questionnaire marketing; e-sales consists of recommendation system and incentive/discount promotion.; e-service is composed of e-mail call center and web call center. From the online survey, 146 responses are collected and analyzed. The analysis shows that the level of experience in campaign/event marketing, e-mail marketing, e-mail call center, and web call center significantly affect the website visit by customers and that the level of experience in all eCRM functions except e-mail marketing significantly affect the purchase by customers. The effects of those functions in eCRM on the website visit are moderate, while the effects of the functions on the purchase are low. The results from this study imply that eCRM needs to strengthen the effect on the purchase with more thorough analysis of the customer profile.

The purposes of this study were to (a) identify dimensions of relational benefits in the social commerce market, (b) predict the effects of relational benefits on satisfaction, repurchase intention, and word of mouth (WOM) intention, (c) examine the mediating effects of satisfaction, and (d) compare the differences in the effects of relational benefits on satisfaction, repurchase intention, and WOM intention between the two groups of market mavenism. For collecting data, a self-administered questionnaire was undertaken by an online research agency. A total of 490 usable responses were obtained from consumers who have used social commerce sites. The sample included a slightly higher number of females (50.8%) than males and age was ranged from 20 years to 40 years. An exploratory factor analysis generated four factors of relational benefits such as confidence, convenience, special treatment, and information. Multiple regression models showed that confidence, convenience, and special treatment benefits were significant predictors of satisfaction and repurchase intention; the confidence and convenience benefits were significant for WOM intention. Satisfaction significantly mediated the relationship between relational benefits and repurchase intention, and the relationship between relational benefits and WOM intention. The group with high level of market mavenism more highly perceived the relational benefits than the other groups. Confidence benefit had a significant effect on repurchase intention regardless of the level of market mavenism, while convenience benefit had a significant effect on repurchase intention in the non-market maven group. This study discussed the managerial implications for customer relationship management in the social commerce marketplace.

The purpose of this study was to analyze the key factors considered important by customers in the selection of a Korean restaurant through the use of conjoint analysis techniques. A total of 400 questionnaires were distributed over a 2-week period in October 2011, of which 354 were completed (88.5%). Statistical analysis was then carried out using the Windows 18.0 Statistics package. The research was based on the analysis of two target areas - daily meals and special purpose meals. Responses were measured by using Zaichkowsky's Personal Involvement Inventory (PII) and a 7-point Likert Scale. Overall it was found that in all areas of the results regarding the involvement related analyses, daily meals scored lower than special purpose meals. This implied that the choice of daily meals is more applicable to customers with a low level of involvement, whereas high-involvement customers were more likely to focus on special purpose meals. The analysis of high-involvement customers revealed that the quality of food, price, service quality and physical environment, in order of priority, were the most important factors in selecting a restaurant. The use of the optimum attribute combination revealed the following results: delicious food (0.601); friendly staff (0.170); clean restaurant (0.191); price of 20,000 won (-0.513). Furthermore, low-involvement customers considered the following factors as important when selecting a Korean restaurant: quality of food, followed by price, physical environment and service quality in that order. In this instance, the optimum attribute combination showed the following outcomes: tasty food (0.645); friendly staff (0.418); clean restaurant (0.365); price of 5,000 won (-0.847). These results indicated the importance of developing a marketing plan which was based specifically on a customer's involvement level, focusing on their main selection criteria when choosing a Korean restaurant.

This study uses a survey questionnaire to identify the major customer age class of adult women who frequently mountain climb as well as analyze their purchasing behavior and preference of mountain climbing pants. The field survey, classified the types of mountain climbing pants, selected the types of mountain climbing pants that consumers preferred, and then analyzed the degrees of satisfaction for mountain climbing pants based on an evaluation of wearing. Specifically, the patterns of mountain climbing pants preferred by national brands and licensed brands were compared and analyzed. The validities of commercially available mountain climbing pants were analyzed through an evaluation of wearing comfort and an evaluation of wearing on a 3D simulation of the human body. The basic data for the development of mountain climbing pants are presented based on the results. The survey questionnaire results indicate that the major class of women consumers of mountain climbing goods was in the 40s to 50s; in addition, the types they most wore were straight type and functional cut type. The preferred brand was KOLONSPORT (which occupies a 21.2% market share), followed by THE NORTH FACE (13.0%), K2 (11.5%) and Kolping (10.0%). The main reason (26.8% of responses) that they preferred these brands was functionality. The difference in measurement of climbing pants patterns could be analyzed accurately in the pattern analysis, the wearing evaluation by the self-sonsory test and evaluation of wearing comfort through 3D simulation. The results of ANOVA on motions and items indicates that no significant difference was found among motions; however, a significant difference was recognized among items. A comparison of straight type and functional cut type showed that the functional cut type excelled slightly in wearing comfort.

This study was conducted to assess factors associated with the degree of performance of qualify improvement(QI) activities. A mailed questionnaire survey was conducted between September 15 and October 30, 2000, with the staffs being charge of QI at each of the hospitals with 400 beds or greater. Of the 108 hospitals eligible for inclusion in our study, 79 participated, yielding a response rate of 73.1%. After excluding 12 hospitals that did not perform any QI activities, 117 responses from 67 hospitals were used for the analysis. Using the Malcolm Baldrige National Quality Award Criteria(MBNQAC), perceived performance of QI was measured in terms of the improvement of the quality of clinical practice, clinical supporting department, administrative procedure of receiving care, customer satisfaction, efficiency and standardization of work process. Factors evaluated for the association were the extent of QI implementation, compliance to 5 QI principles, participation of hospital CEOs, budget allocation, history of QI, and bed size. Path analysis was performed to assess the relationship between QI performance and these factors. Major findings of this study are as follows. Hospitals showing higher degree of QI implementation (path coefficient=0.5967, p<0.001)) and better compliance with the basic principes of QI(0.5736, p<0.05) tended to achieve better performance. Path analysis results showed that interest and participation of hospital CEOs(0.1954, p<0.05) and compliance with the basic principes of QI(0.4028, p<0.0001) indirectly affected the outcomes of QI by influencing the intermediate variable of the level of QI implementation. This study results suggest that having employees have a good orientation of the basic concept and principes of QI through relevant training be the most important requirement to achieve better outcomes from QI activities. In addition, to educate leaders of hospitals the need of active implementation of QI is important to encourage their participation and draw strong support for QI programs.
