The current research utilized as its target population who are current users of global small to medium sized companies in Korea. The research validated the innovative dimensions by studying the two constructs within the context of the SMB user population. Correlation was found between innovative dimensions retained as components of a Comprehensive Model. It was determined that these four dimensions-Content, Intrinsic Interest, Control, and Timeliness-are significant predictors of user success. The Comprehensive Model was validated, and it is therefore suggested as a basis for further study of user success indicators in the innovative manufacturing enterprise environment.

The purpose of this study is to estimate and analyse the relationship between Chinese price and the price of Korea, United States, and Japan. First of all, We test for a unit-root for stability of variable. This paper employs GPH cointegration test since the model must be stationary to get the accurate predicted values. The empirical results show that the model is mean-reverting. This paper also applies impulse-response functions to the model. The empirical results show that the price of Korea, United States, and Japan respond positively to the shocks in Chinese price and then decay slowly.

The purpose of this study was to analyze which factors have had impacts on extension export insurance charge of Korean export insurance. In order to attainment of this study, an empirical study was proceeded. The export insurance charge was hired as the dependent variable and export insurance premium, insurance compensation charge, export insurance collection charge and export insurance fund were used as independent variables. Data was used for estimation are the annually data from 1969 to 2007. From results of this analysis, we find the hired variables have highly correlation among them and the most influential factor turns out to be export insurance fund. Main results of this study was as follows : i) The export insurance fund must be increased immediately. ii) It is necessary that Korea Export Insurance Corporation give their attention to the compensate amount of export insurance compensation on specific insurance item. iii) It is necessary that Korea Export Insurance Corporation extension the collection efforts of the export insurance. iv) A reasonable raising of export insurance premium need to be done.

The current paper reviews the main characteristics and the operating principles of major fuel atomizers used for gas turbine combustors, including various empirical SMD equations for each atomizers. We have summarized various methodologies for evaluation of the combustion efficiency and for combustor sizing from the selected SMD data. It is found that the combustor sizing as well as the combustion efficiency are totally dependent upon the SMD calculation results, which means that special cares should be taken in choosing the SMD empirical equations.

In a global market environment with information technology, the textile and apparel industry tries to survive by having competitive power embedded in Supply Chain Management to improve the interrelation among different stages of industries such as fiber, textile, apparel manufacturing, and retailing. The purpose of this empirical study was to investigate performance on Supply Chain Management of textile firms such as 4 textile export firms and 10 collaborate firms which were adopted SCM system. For research methodology, we developed questionnaires based upon interview and literature review. The results of this study were as follows: There were neutral responses or somewhat dissatisfactions on SCM application from CEOs, CMOs, site workers, and collaborators, but over half of respondents indicated 21-40% improvement of affairs. Standard documents and information sharing of SCM system were salient effects. SCM system with standard documents improved receipts/payments and inventory management most.

The purpose of this study is to find essential delivery service quality elements of internet shopping mall and to investigate the relationship among delivery service quality, satisfaction, trust, and loyalty in the area of internet shopping malls. To do so, theoretical literature review and empirical survey accomplished. The empirical results of this study are summarized as follows. Firstly, accuracy, quickness, safety, information providing, and institutional guarantee have a positive influence on satisfaction. Secondly, accuracy, quickness, information providing, and institutional guarantee have a positive influence on trust. Lastly, satisfaction has a positive influence on trust, and both of satisfaction and trust have a positive influence on loyalty in internet shopping malls. From the analyses of this study, we offer several implications both theoretical and practical perspective.

Many empirical research surveys have supported that Organizational Citizenship Behavior (OCB) is influnced by or closely related with leadership styles. The first purpose of this study is to review the relationship between 2 leadership styles(employee-centered style, job-centered style) and 2 OCB factors(altruism, conscientiousness) as a criterion variable, and the second and primary purpose is to test the moderating effects of structural factors(formalization, centralization) and personal factors(growth needs, sex, age, tenure, rank, occupation, school career) between 2 leadership styles and 2 OCB factors. For the analytical purpose of this article, Fisher's Z-transformation and SGC(split groups correlations) methods were introduced. Generally 2 leadership styles are found to influence on altruism and conscientiousness respectively. Out of 36 cases, only 2 cases were significant in moderating effects. Based on empirical results, there is no moderating effects in conscientiousness. But altruism is found to more closely related with employee-centered leadership in low centralized group than on high centralized group, and more closely related with job-centered leadership in low growth-needs group than in high growth-needs group.

The purpose of this study is to develop a new equipment acceptance model in the industrial market and test it empirically using a field survey. To define new equipment acceptance factors of employees in the organization, we used the TAM as a useful model to analyze the acceptance process of new equipment. All of the data for the TAM were collected from the employees. Prior research studied the usage of general information technology using a computer and particular software, while we apply the TAM to the new equipment adoption. In this study, both theoretical review and empirical study were conducted and the model was set through the theoretical study which was tested through the empirical analysis. Management support and training/education were shown to have a positive effect on PU and PEOU. Personal innovativeness, management support, perceived usefulness and perceived ease of use were shown to have a positive effect on behavioral intention.

Since Capital Asset Pricing Model(CAPM) was proposed in the early 1960s by William Sharpe(1964) and John Lintner(1965) researchers have investigated the validity of the model. The results of empirical researches do not show that expected returns of stocks seem to be determined solely by systematic risk of the stocks as precicted by CAPM. In this paper the relationship between transaction volume and expected returns of stocks was investigated. Empirical cross-sectional analysis about the data collected from Stock Market of Korea Exchange shows transaction volume and variability of stock returns play an important role in pricing assets. The well-known variables which were used traditionally to explain the differences of expected returns among stocks such as the size and beta of a stock seems to be unimportant in pricing assets.
