오늘날 온라인 쇼핑몰 기업들은 이용고객의 다양한 필요와 욕구에 부응하기 위하여 여러 가지 새로운 상품 및 보다 나은 서비스를 제공하기 위해 노력하고 있으며, 새로운 웹 사이트의 출현으로 인해 업체 간 경쟁도 치열해지고 있는 실정이다. 따라서 온라인 쇼핑몰업체들은 이용고객의 이탈을 방지하고, 이용고객과의 지속적인 관계를 장기적으로 유지하여 기업이 제공하는 제품 및 서비스에 대한 고객의 만족도를 높여줌으로써, 애호고객으로의 전환이 가능하도록 할 필요성이 있다. 본 논문의 목적은 심미적 매력, 공간 기능성, 결제 안정성, 머천다이징 4개의 차원으로 압축된 온라인 물리적 환경으로서의 e-servicescape의 개념적 모델을 제시하고, 이 개념과 신뢰 및 구매의도의 관계를 논의하기 위함이다. 또한 기존의 온라인 연구를 물리적 환경으로 개발하고 확대하기 위한 것에 목적을 둔다. 본 연구의 첫 번째 공헌은 첫째, 온라인 물리적 환경에 대한 이론적 종합과 조작적 정의를 포함하고 있다는 것이다. 둘째, 신뢰가 온라인 거래에 중요한 변수라는 것을 발견한 것에 있다. 셋째, 소비자의 구매의도의 선행요인에 대한 통찰에 대한 공헌이다. 마지막으로 온라인 환경에 대한 소비자의 이해는 신뢰와 구매의도에 대해 상당한 영향을 가하고 있다는 것을 본 연구를 통해 알 수 있다.

We define product line (or mix) selection problem as selecting a subset of potential product variants that can simultaneously minimize product proliferation and maintain market coverage. Selecting the most efficient product mix is a complex problem, which requires analyses of multiple criteria. This paper proposes a method based on Data Envelopment Analysis (DEA) for product line selection. Data Envelopment Analysis (DEA) is a linear programming based technique commonly used for measuring the relative performance of a group of decision making units with multiple inputs and outputs. Although DEA has been proved to be an effective evaluation tool in many fields, it has not been applied to solve the product line selection problem. In this study, we construct a five-step method that systematically adopts DEA to solve a product line selection problem. We then apply the proposed method to an existing line of staplers to provide quantitative evidence for managers to generate desirable decisions to maximize the company profits while also fulfilling market demands.

Purpose - Recently, internet access and social network utilization using smart phone are increasing. In such a smart environment, interactive activities such as information generation, information searching and information sending are increasing rapidly on-line environment. Therefore, consumers tend to purchase something according to eWOM and also meet the social consensus online environment. In connectivity society, consumers became accessible and engaged in the opinions of others easily. Many decisions that seem like personal decisions are actually social decisions on online connectivity. This paper seeks to explore factors that can help generate a social decision on purchasing of new products in an online environment. Research design, data, and methodology - The process of collecting a lot of wisdom and making an agreement online is called social decision. The purpose of this paper is to examine empirically the influence of factors such as online ties, online eWOM expectancy and online information behavior on online social decision. In addition, We studied online social decision by analyzing the moderating effect of new product innovation. To understand this structural relationship, research hypotheses and research models were set up and empirical analysis was conducted. In order to verify the hypothesis, 208 questionnaires were collected from the residents of Seoul city/Gyeonggi province. The answered questionnaire verifies reliability and validity using SPSS/AMOS and test hypotheses through path analysis and multiple regression analysis. Results - According to the research results, First, online ties don't have a positive impact on online social decision, Second, online eWOM expectancy have a positive impact on online social decision. Third, online information behaviors have a positive impact on online social decision. The degree of innovation of new products have a moderating effect between Independent variables of three factors and dependent variable of social decision. Conclusions - Social decisions have a positive impact on purchasing decisions about new product. There is a great significance in the fact that the online social influence and online social decision have been studied academically. It is meaningful that we have studied in depth the changing phenomenon of consumer purchase decision process in smart environment. The results of these studies provide academic and practical implications.

This paper analyzes arc phenomena including the secondary arc's elongation in the Korean 765kV single transmission line (79km) between Sin-Ansung S/S and Sin-Gapyeong S/S, which will be installed in Korea in June 2006. In particular, both frequency independent and frequency dependent line models are compared to make our final decisions. As well, the significant simulation results are investigated by the EMTP program. As a result, there is no need of HSGS in the Korean 765kV single transmission line from both a practical and an economical point of view.

The whole track system is designed and maintained to provide satisfactory geometry. Renewal and collection decisions are often governed by track irregularities. To provide cost-effective track to meet in the need in the future it is essential to be able to improve the methods by which the performance of the track is monitored and to have reliable methods for prediction and planning. This paper develops computer-aided system for analysis and management of track irregularities. The main objective is to collect and monitor track irregularities for each conventional line to be used as an aid in making decisions on track correction and renewal. The final decision especially on track renewal, however, always be a decision made by man and not by computer-aided system.

Purpose - The purpose of this study is to provide a formalized process of decision making for companies or organizations that need to make various decisions in the age of uncertainty. Therefore, this study aimed to proposes a strategic decision-making approach citing the relatively easily accessible using IPA(important-performance analysis) and SWOT/AHP analysis. Research design, data, and methodology - To be specific, the first step is to derive necessary attributes and conduct IPA. The second step is to subdivide the IPA results into internal strength and weakness factors and the external opportunity and threat factors, hierarchize those factors, and weight them accordingly. The third step is to build a causality model to propose a method of supporting a rational decision making. Results - The foregoing approach seems to facilitate the diversification of decision-making strategies by helping businesses or organizations to measure and analyze the attributes needed for certain decisions. Additionally, the perceived importance and satisfaction (or achievement) usage of those derived attributes can be used as the reference data for SWOT/AHP analysis. Conclusions - The proposed stepwise approach is applicable to businesses or organizations in need of making stepwise decisions in line with their retained competencies in comparison to conventional or intuitive decision-making practices.
