This study is to analyze the efficiency of Korean software companies listed on the KOSDAQ. Data Envelopment Analysis is employed to estimate the efficiency of 44 software companies. In addition, super efficiency is used to differentiate the performance of the efficient software companies. We used total assets, wages, cost of goods sold, sales and administrative expense as inputs, and revenue as output. The result indicates that 7 DMUs of 44 DMUs are efficient. Of the 37 inefficient DMUs, 17 DMUs are operating under conditions of increasing return to scale. In order to attain greater efficiency, increasing in inputs is recommended for DMUs under IRS. The result of super efficiency shows that DMU 14 is the highest ranked one of all the efficient DMUs.

This study investigated the influence of organizational justice, organizational commitment, program commitment, and organizational learning climate on Six Sigma performance. A majority of existing research of Six Sigma has focused on technical aspect of Six Sigma with anecdotal case analysis. To overcome the restricted area of research interest and methodological limitation, this study focused on the effects of organizational variables that are expected to have an influence over Six Sigma performance with survey method. The data were collected from 184 employees of 23 public-sector companies and were analyzed by structural equation modeling method. The results show that organizational fairness and organizational commitment affects Six Sigma program commitment that, in turn, affects perceived Six Sigma performance. Contrary to our hypothesis, learning organizational atmosphere does not show statistically significant moderating effect on the relationship between organizational justice and program commitment. Practical implications and future research directions were suggested.

The purpose of this study is to investigate shopping satisfaction of Japanese tourists visiting Korea. For this study a questionnaire survey was conducted on 200 Japanese tourists visiting Korea during the period of November 10th to December 20th, 2007 at Incheon International Airport, Korea. We use the gap approach to measuring satisfaction. The satisfaction characteristics studied are nine: price, quality, design, performance, package, knowledge, attitude for customers, communications and transportation. Satisfaction is measured by the differences or gaps between perception and expectation values for each of the nine characteristics. For eight of the nine satisfaction characteristics, the differences are significantly greater than zero indicating satisfaction except price. The overall level of shopping satisfaction is estimated to be 4.920 significantly greater than the mean of the measurement scale. This may be taken that Japanese tourists visiting Korea are quite 'satisfied'. However, further efforts to improve the level of satisfaction are necessary for packaging and explanation of products and services. Price does not seem to be a critical factor for shopping in Korea

Most of marketing literature and studies consistently identified customer satisfaction as a key antecedent to customers’ loyalty, WOM and repurchase. But these are indirect components to explain CS’ contribution to firm's profitability, fails to explain direct relationship. So we tried to discover direct relationship between CS and firm's profitability using real purchase price. To discover the relationship between CS and purchase price we used equity theory. Equity theory suggests that if customers experience elevated states of satisfaction, they perceive a high outcome of an exchange and therefore are willing to pay more than less satisfied customers because this results in an equitable ratio of outcome to input. The objective of this study can stated as two folds. This study shows relationship between customers’ satisfaction on their real purchase price for the product first. Second, this study finds linear effect and nonlinear effect in satisfaction - outcome link. There is no consensus about the functional structure for this specific relationship. Using previous research of WTP this study hypothesize about the functional structure. As a result of the research, we can confirm the fact that the relationship between CS and purchase price, the primarily purpose of the research, is affirmative. Our study illustrate the usefulness of equity theory in understanding the relationship between pricing issues and satisfaction. But we can't address nonlinear effects on outcomes of satisfaction. The theoretical and practical implication of this paper can be stated as follows. As we said our research reconfirm the managerial belief that satisfied customers who are really pay more by huge survey data. This research has important implications of investment in CS and for setting prices. Further research should explore the functional structure of the relationship in more detail.

In this study, the technology index by product was estimated considering the fact that the technical standard for manufacture differs depending on the product. As result of analyzing the technical standard of major countries and their technical standard by industry using the Technology Index estimated in this study, it was found that generally, the technical standard of advanced nation was higher than that of the underdeveloped nation. Considering the industry’s perspective, the study also determined that the technical standard of the advanced nation was higher across all industries. In case of medical, precision, and optical instruments, watches industries, machinery & equipment industries. however, they showed much more differences than the textile or apparel-clothing industry. In view of the electronics industry, the technical standard of all nations showed the standard’s tendency to become low, and there was not much gap between the nations and the other industries. This is possibly because the manufacture of electronic products becomes standardized as the goods are manufactured in different countries. As result of the study analysis, there was a significant relationship between the Technology Index and TFP. Moreover, the analysis that factors in the education level showed significant relationship between Technology Index, education and TFP in the high- income earning nations. In view of these results, the Technology Index estimated in this study is believed to be a useful variable in predicting the export competitiveness of the high-income earning nation.

The purpose of this study is to show the customer differentiation strategy of an Airway VIP Lounge. The enterprise VIP Lounge differentiation strategy of glow from competitive time is very important. It leads and the service strategy which is differentiation a customer satisfaction index and raises the corporate strategy establish which leads the image differentiation of the enterprise and makes. Like this service strategy is the first time subject the VIP Lounge must service in the world-wide time which diversifies. According to satisfaction of this customer research result the discrimination craving of the customer was segmented. The customer differentiation strategy becomes effect and re-positioning of the image of the enterprise. so consequently the re-use needing and customer satisfaction index were investigated on a large scale.
