PSS (Product-Service Systems) 개발에 있어서 중요한 요소로서 사용자의 경험을 들 수 있다. 제품개발 시 가장 중요하게 고려되는 요소로서 고객의 요구 (customer requirement)와 니즈 (needs)가 언급되곤 한다. 고객의 요구나 니즈는 실제로 관련 제품이나 서비스를 사용해 본 고객의 경험에 근거하고 있다. 따라서 고객의 경험을 제대로 파악하고 이를 추출하는 것이 성공적인 제품개발의 시작이다. 본 연구의 목적은 사용자 경험을 활용하는 제품-서비스 시스템 (UXPSS)을 위한 프레임워크 모델을 개발하고 샘플 제품에 대한 구현을 실시한다. 이를 위해서 사용자 경험, 제품의 서비스화, 서비스의 제품화, 서비스 사이언스, 기능분석 및 모듈화를 결합한 통합 모델을 개발하고 이를 실험적으로 구현해 본다.

The purpose of this study was to understand fashion product consumers' relationship dissolution by considering the characteristics of customer behavior and examining the connection between the main variables. The survey was conducted on 623 women over 20 years old who had experienced relationship dissolution or problems with regular fashion stores in the areas of Seoul and Kyungki in September 2005. The SPSS 12.0 package and Amos program were used to analyze the data. The results of this study were as follows: First, service recovery justice of a fashion store, interactional justice, distributive justice, and procedural justice had effects on encounter satisfaction. Furthermore, encounter satisfaction influenced relationship dissolution behavior, voice, exit, loyalty, neglect via overall satisfaction. Second, there were differences in relationship dissolution behavior according to consumer loyalty and switching costs.

This research investigates the present situation of petroleum market and the potential strategy which help gas stat ion obtain compel it ive advantages. Specifically, this research chooses five factors (product quality, service, price, multi-function, easy entrance) which are believed to be extensively related to repurchasing intent ion. The findings are as follows ; First, four factors associated wi th gas stat ion choice (product quality, service, price, multi-function) are related to repurchase intent ion 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.

Generally, a system or service is verified by requirements if it has met them in transforming customer requirements into a system or service. But as the national research and development projects to develope safety systems or standards or process in railway system domain, it can be quite limiting that the product or systems verification process presented the international or industrial standards to be applied. This paper has analyzed and made up for the general verification process and presented the effective and efficient verification process about safety system, safety standard, process, and safety documents and the methods to manage the outcomes of verification process.

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.

Evaluation indices for products or services are important to improve the internal process of the company and to compare those with competitive ones. The sigma level in Six Sigma management does important role to evaluate the core characteristic, CTQ(Critical To Quality), derived in the considered product/service or process. In this research, we propose an overall evaluation index for the product/service or process with multiple characteristics, in other words, multiple CTQs. The proposed overall evaluation index is useful for the cases that the single CTQ is not enough to evaluate the practical interests, for example, the final products and services with complex procedures and relatively large scaled processes. This approach is discussed with sigma level for applying Six Sigma Projects, however, it is applicable to indices based on proportion or percentage as well. The practical examples with a manufacturing process and a customer survey based on focus group interview are given for illustrations.

With the development of mobile and wireless environments, the Ubiquitous era has com on the base of technologies of Semantic Web and Web Services. To accelerate proliferation of the E-Commerce in the Ubiquitous era, the importance of information search is emphasized more and more and its time to need more intelligent search for product and service which can consider location and other context-aware related information. As a starting point to meet these requirements, we proposed more effective product information search service framework through web services under semantic web environment. Over the wireless internet and we also examined its technical validity with the prototype system, implemented prototype and investigated the technological possibility.

This paper is concerned with warranty cost models for a product with two types of failure ; type 1 failures corrected by minimal repair and type 2 failures removed only by replacement. Two warranty policies involving an initial free service period followed by a pro-rata period are considered ; the difference is whether the warranty is renewed or not when type 2 failure occures during its free service period. Expected warranty costs under the two policies are obtained, and their behaviors are examined for the case where type 1 and 2 failure distributions are Weibull and exponential, respectively.

This study proposes a web presence readiness model based on pre-payment service functions and a post-payment service function both of which embrace the major concerns of customers in the online purchasing context. Based on the concept of customer utility from the product itself and instrumental utility, the research model suggests four antecedents including, Perceived Economic Benefits, Product Search Support Quality, e-Shopping Method Diversity, and Post-Payment Support Quality. We empirically examined a proposed research model using data collected from online rating company websites. Among the four antecedents, post payment support quality is found to be the most influential determinant of customer evaluation on e-commerce websites. Based on the empirical results, the current study proposes an alternate model of web presence readiness. The findings of this study may provide an insight to field practitioners designing commercial websites. The implications and future research directions are further discussed.

With rapid growth and competition of electronic commerce through internet, various buying types and business models are being appeared. In this paper, we studied group buying which is new business model to consumer and factors affecting on trust and participation of group buying. The followings are the regression result of this study. First, familiarity factor, customer service factor, seal of security and product value factor made a significant effect on trust. Second, familiarity factor, perceived reputation factor, customer service factor, seal of security and product value factor made a significant effect on participation of group buying. Third, trust of group buying made a significant effect on participation of group buying. In this study, modeling and empirical test were implemented about structure of trust and participation of group buying. We can know where our group buying strategies should focus and which factor we should improve.
