Purpose: This study focused on procedure and methodology for finding the critical design factors in the early stage of product development process. Methods: Firstly, three key criteria, function, affection and usability were defined as the determining factors on customer satisfaction. Secondly, evaluation matrix in terms of each key criteria was proposed for extraction of the critical design factors. Lastly, method of integrating the importance among three key criteria was suggested using structured equation model. Results: As a results of integrating the importance, design factors such as touch sensitiveness and touch method were rated as low in terms of affection. However, these factors were obtained for high ratings with respect to functionality and usability. Thus, touch-related design factors were more facilitated for enhancing customer satisfaction. Conclusion: It is expected that the process suggested in this research could be a considerably useful to maximize customer satisfaction in the early stage of product development process.

This study aims to measure effects of cause-related marketing by using consumer's preference of cause-related marketing product as a dependent variable. One of main factors influence on preference of cause-related marketing product is a product type. Previous research has shown that hedonic product is more effective for cause-related marketing than utilitarian product. The result was largely explained by the logic of guilt. However, there were conflicting results. In addition, the level of guilt may vary depending on the consumer characteristics or the market environment. Therefore, this study focuses on the impact of product type on the effect of cause-related marketing. For the Korean and Chinese markets, this study examines the effect of interactions between countries and product type. The result was significant. Specifically, there was a difference in preference of cause-related marketing product between Korean and Chinese consumers by product type. Based on the findings, implications and limitations of this study and future research directions were presented.

This research investigates the present situation of petroleum market and the potential strategy which help gas station obtain competitive advantages. Specifically, this research chooses five factors (product quality, service, price, multi-function, easy entrance) which are believed to be extensively related to repurchasing intention. The findings are as follows; First, four factors associated with gas station choice (product quality, service, price, multi-function) are related to repurchase intention except easy entrance. Second, sex and age have moderating effects between factors and repurchase intention. To keep and preoccupy new customers, the administrators of petroleum industry and gas station should establish sales/administration strategies considering these above.

Starting with the meaning of the word quality, diverse concepts connoted by the term are examined. Instead of a bathtub curve, the desirable shape of a failure rate covering the entire life of a good product, which might be called hockey-stick line, is introduced. From the hockey-stick line and the definition of reliability, two measurements are extracted. The terms reliability, failure rate, product life, and durability are explained. From the customer's standpoint, the concept of product quality is classified in five factors, according to related technology: performance, reliability, conformance to specifications, customer perception, and fundamentals advantage. The correlation of the five factors for a first-class product is discussed, Since the market share of a company is determined as the competition result of its product value, defined as product quality and price, the market share increase is derived mathematically from the increment of product value. The market share increase, $\Delta$S, can be calculated from the present market share, S, and the oriented relative value increment of new product, R, to the current product in the same company for the same market target: $\Delta$S : $\Delta$(1-S). R/(1+S.R). Finally, the importance of separating warranty cost from the profit equation for the durables is explained.

This study examined the sales pattern relationship with respect to product attributes to propose sales forecasting for fashion products. We analyzed 537 SKU sales data of T-shirts in the domestic sports brand using SAS program. The sales pattern of fashion products fluctuated and were influenced by exogenous factors; therefore, we removed the influence of exogenous factors found to be price discounts and holiday effects as a result of regression analysis. In addition, it was difficult to predict sales using the sales patterns of the same product since fashion products were released as new products every year. Therefore, the forecasting model was proposed using sales patterns of related product attributes when attributes were considered descriptive variables. We classified sales patterns using K-means clustering in order to explain the relationship between sales patterns and product attributes along with creating a decision tree classifier using attributes as input and sales patterns as output. As a result, the sales patterns of T-shirts were clustered into six types that featured the characteristic shape of peak and slope. It was also associated with the combination of product attributes and their values in regards to the proposed sales pattern prediction model.

This study analyzes the mechanism that explains how various service quality factors are related to consumer satisfaction when plus-size and regular-size women are engaged in fashion shopping. We constructed and tested service quality- perceived value-satisfaction model with size as a control variable. We defined plus-size women as those with a BMI over 25 and regular-size women below 25. Data were collected during April and May, 2012 and responses from 189 plus-size women and 246 regular-size women were used in the final analysis. The results are as follows. First, among service quality factors, attention was significantly related to perceived service value for both plus-size women and regular-size women. However, store facilities were significantly related to perceived service value for only plus-size women and kindness was significantly related to perceived service value only in the case of regular-size women. Second, perceived service value was significantly related to product satisfaction and service satisfaction for plus-size women and regular- size women. However a moderating effect was found between the groups where the influences of perceived service value on product satisfaction and service satisfaction in the case of plus-size women were greater than regular-size women. Third, in the case of regular-size women, service satisfaction was positively affected by product satisfaction. However, the relationship between them was not found in the case of plus-size women.

This study examined the evaluation of Mongolian cashmere products by foreign tourists visiting Mongolia, purchase motivation, and purchase intention by nationality as well as analyzed factors that affected purchase intentions. Questionnaires were distributed in Ulaanbaatar from July $25^{th}$ to September $3^{rd}$, 2012. We collected 626 questionnaires and used 616 copies in the final analysis (149 from Koreans, 128 from Japanese, 119 from Russians and 220 from English-speaking countries). Awareness about Mongolian cashmere products and purchase intentions differed significantly by nationality. Purchase motivations were divided into 3 factors-usefulness, mood shift, gifts and souvenir. Evaluation of cashmere products consisted of 5 factors-product excellence, uniqueness, ostentation, economic value and fashionableness. Purchase motivation and evaluation differed significantly by nationality. Purchase intention was significantly related to awareness prior to visit, product excellence, usefulness, gift/souvenir motivation factors, and nationality.

Nowadays, customers have increasing needs, so more and more enterprises are selling their products with additional services and or contents. The emergence of service added to the product leads to the emergence of the Product-Service Systems(PSS). Many researches related to PSS are mainly concerned with general PSS and PSS modeling, which can not readily assist manufactures of consumer products to implement and realize PSS solution. We have wondered whether customers can distinguish service functions from product functions. Through the case studies on Apple and Nintendo and the survey on the representative 5 IT products, we propose the design factors of products and services for PSS.
