  • Our goal of this study is to confirm whether manufacturing companies' practicing JIT production system have positive effect on production performances and to confirm that manufacturing companies' practicing SPC shows positive moderate effect on the relation between practicing JIT and their production performances. Based on empirical study to manufacturing companies nationwide, we can conclude that taking JIT practices of sample companies has positive effect on production performances and, moreover, practicing SPC has positive moderate effect on the relation between JIT practices and production performances. These conclusion represents managerial implication that concurrent practicing JIT and SPC could generate more improved production performances.

  • Purpose: The purpose of this study was to investigate if companies' efforts of environmental management practices have positive effect on the companies' performance in the first stage of study. In the second stage, we tried to confirm whether the degree of companies' making efforts on cost leadership strategy and quality leadership strategy function as moderate variable on relationship between environmental management practices and performance. Methods: The collected data through survey were analysed using multiple regression model in the first stage of the study and moderate regression model in the second. Results: The results of this study are as follows; environmental management practices have positive effect on corporate performance. Moreover, much effort on quality leadership strategy has limited significant moderate effect on relationship between environmental management practices and performance, while much effort by companies on cost leadership strategy does not have significant moderate effect on the relationship between the two variables. Conclusion: Manufacturing and services companies in Korea need to make effort for environmental management practices to improve corporate performance. Moreover, if that efforts are combined with quality leadership strategy, they can expect synergy effect with environmental management practices for performance improvement.

  • We classified quality management practices of manufacturing companies into 'Infra' factor and 'Process' factor which were introduced based on existing literatures and previous studies related to quality management. It was our first objective to confirm its conformance in Korean manufacturing industry, and to examine the two factors effect positively on production performance. Moreover, we tried to examine whether JIT and workforce management have an moderate effect on 'Infra and Process factors-performance' relationship, using moderate regression. As the result of empirical study on nationwide manufacturing companies, we had the results that the classification between Infra factor and Process factor in quality management practices was valid in Korean manufacturing companies, and that the two factors gave performances positive effect. Moreover, our secondary analysis showed that JIT had an positive moderate effect on the Infra factor while workforce management on the Process factor. With these results, we have an interpretation that manufacturing companies which aim to enhance short term performances have to concentrate their effort and investment on Process factor and, on the other hand, ones which aims to improve long term performances on Infra factor.

  • Recently, the concept of web site stickiness receives attention as a measure of strategy to influence user's visit and behavior on web sites. Web site stickiness means site visit frequency and stay duration. This study investigates the moderating effect of espoused national cultural values on Internet community stickiness with the assumption that dimensional values of national culture can be internalized as individual’s espoused values. Espoused values (i.e., espoused national cultural values) are defined as the degree to which an individual embraces the values of his or her national culture. Our findings can be summarized as follows. First, femininity and power distance moderate the influence of user participation on Internet community stickiness. Second, uncertainty avoidance and power distance moderates the effect of social influence on Internet community stickiness. However, femininity and collectivism do not moderate the effect of social influence on Internet community stickiness. Third, uncertainty avoidance, femininity, and collectivism moderate the influence of network effect on Internet community stickiness. Fourth, masculinity does not moderate the influence of usefulness on Internet community stickiness.
