The unprecedented growth of Internet technologies has made resources on the World-Wide-Web(WWW) instantly accessible to various user communities. While e-commerce has become as an important issue with the growth of the Internet, there are insufficient empirical research efforts concerning its status in Korea. The United States, in contrast, has made significant efforts in making empirical research regarding this issue. In this paper, we demonstrate not only how these contextual differences influence consumer satisfaction with the purchased products/services, but also what contextual constructs make consumers satisfied or dissatisfied. In addition, we tried to find the difference in the factors of consumer satisfaction between a developed country(i.e., United States) and a developing country(i.e., Korea) with regard to e-commerce. The study findings suggest that contextual problems need to be solved before e-commerce provides real benefits for consumers and businesses.

In this paper, a life distribution fitting method based on generalized phase-type distributions(GPH) is presented. By fitting the life distribution to a GPH, we can utilize various useful properties of the GPH. Two different approaches are used according to the properties of the given failure time data. One is an approximation to a GPH through the piecewise Weibull failure rate(PWF) model and the other is a direct approximation to a GPH using the empirical distribution function. Two numerical examples are also presented. In the first example, both of the two approaches are utilized and compared for an incomplete data set. And in the second example, the direct approximation method from an empirical distribution is utilized for the analysis of a complete data set. In both cases, we could confirm the validity of the proposed method.

This paper aims to explore the strategic roles of information and strategic planning capabilities for firms' performance, and to examine the direct and indirect relationships between information capability, strategic planning capability, logistics performance and competitive advantage. The present research adopts resource based theory (RBT) to explore the relationships between a firm's specific capability and its performance and employs structural equation modelling (SEM) in order to test the validation of the measurement models and examine the relationships between construct variables. The current empirical test was conducted using the data collected from logistics managers of 101 Korean electronics companies. The empirical research presents positive influential relationships between (1) information/planning formality capability and strategic planning capability; (2) strategic planning capability and logistics performance; (3) logistics performance and competitive advantage; and (4) competitive advantage and competitive position in the market.

Despite the increasing pervasiveness of electronic commerce, very little empirical research has been done to examine its use in organizational contexts. Based on theories from the technological innovation literature, we developed an integrated model of electronic commerce initiation, adoption and implementation in Korea. We selected a random sample of 500 Korean leading companies. A questionnaire survey examined factors in initiation, adoption, and implementation of electronic commerce. Independent variables of this research were environment uncertainty, organizational characteristics(namely, organizational size, centralization, and formalization), and information system maturity. The resultant study sample included 62 firms across the industries. The empirical tests of the hypotheses were performed. According to our findings, environmental uncertainty, centralization, formalization, and information system maturity have a significant effect on the electronic commerce initiation, adoption and implementation.

Generally high-tech ventures have few resources with which to withstand unpredictable environmental jolts. Therefore environmental changes may have severe effects on the performance of high-tech ventures. Unfortunately previous empirical studies for predicting the performance of ventures hardly deal with such dynamic changes of performance. We try to examine the performance changes of ventures through a longitudinal study before and after severe environmental changes, namely IMF Bailout Memorandum. For the empirical study, we classified venture firms into four types based on entrepreneur's assessment of their performance changes and investigated how these four types differ in characteristics of entrepreneurs, environment, strategy, and organizational features. We found that differentiation strategies, fit between strategy and environmental changes, entrepreneur's trust and activities such as networking and knowledge accumulation about customers, and decentralized organizational structure were important to the performance changes of high-tech ventures.

Purpose - This study focuses on an empirical analysis of the factors affecting the behaviors of consumers who are extremely attached to branded products, and who commit themselves to renting them. Research design, data, methodology - The survey was conducted on college students enrolled in marketing classes. In total, 240 questionnaires were distributed. A total of 226 were returned. Questionnaires, excluding those that were void, were used for empirical analysis. We confirmed that the research model is sound by using a covariance structural analysis, and estimated its parameters. To estimate these parameters, a maximum likelihood method was used. Results - This study confirms that prominence and self-expressiveness positively affect brand attachment. Further, positive beliefs about, and the practicality of renting branded goods, influence attitudes toward their rental. In addition, commitment to renting branded goods is positively affected by attachment to the brand and attitude towards goods rental. Conclusions - Marketers should manage positive beliefs in and the practicability of renting branded goods, as well as the self-expressiveness and prominence of such products.
