This study addresses the development of a quality measurement of information systems integration(SI) service. Several dimensions which affect on quality of systems integration service have been identified and tested. Also, a measurement tool(questionnaire) of the factors has been developed. To achieve above purpose, extensive literature review and in-depth interview with several SI managers and customers were used. We suggested the analysis framework including performance variables such as quality, customer satisfaction, intention of renewal contract, and contribution to better customer's information system and the quality factors as well. To verify the research framework, collected data from the survey was analyzed statistically. The data from 73 respondents was used for analysis. Consequently, we identified eight factors and developed a 41-item instrument with Likert 5 points to measure the quality of SI service. It was proved that the 41-item instrument suggested in this study was very useful to measure the performance of SI service such as quality and customer satisfaction. Also it was shown that the instrument measured intention of renewal contract and contribution of customer's information system well.

This study investigates the impact of supplier involvement, customer involvement, and employee training on product quality and organizational performance. Based on literature review, this study develops hypotheses and tests them by employing a structural equations model. Using survey data of 193 firms from 22 manufacturing industries, this study empirically shows that the activities for supply chain quality management (SCQM) enhance the quality and organizational performance. Specifically, quality leadership is revealed to be an antecedent of other SCQM activities. The most contributable finding is, while the supplier involvement and employee training directly enhance the organizational performance, customer involvement indirectly improves it via quality performance.

This study was conducted to investigate the effects of service quality and food quality on purchase intention in the electronic commerce of food products. Specifically, the relationship between purchase intention and food quality and service quality was tested based on customer satisfaction and trust, which were measured using the structural equation modeling method. Quality of service was found to affect purchase intention; however, food quality had no positive effects on purchase. Additional analyses should be conducted owing to the conflicting results of the present study. Although the amount of food bought online is increasing rapidly every year, research regarding online food purchasing is not being actively conducted. The results of the present study will help food sellers, buyers, and researchers.

Under the competitive environment of shipping industry, the improvement of the quality of shipping service could be one of the most important factors to be considered in the recent shipping industry. However, there has been little study on the clear concept of the service quality in the shipping so far. The subject of this study is to define the concept of the service quality in the shipping by way of making investigation into the related precedent literatures studied. The quality of service is recognized in general as a degree of gap between the customer's expectation and the perception. Therefore the service quality of shipping could be measured by evaluating the gaps between shipper's expectation and performance of shipping service. If the determinants of the service quality in the shipping are proved, and the discrepancies of expectations and perception between the shipping company and the shipper could be clarified, such a result would be an useful help to establish marketing strategy.

The purpose of this study is to suggest the direction of improving service quality in the defense logistics support. For this, this study compares and analyzes the perceived service quality between customer(using unit) and defense logistics support unit by using SERVPERF model. Supply, military meals, and maintenance are carrying out the mission as core function of defense logistics support and also encounter with customer. In this empirical analysis, the service quality is composed of four factors, and there are significant difference in perception level of service quality between them. Also, the relationship between factors of service quality and revisit intention shows significant difference statistically, and the customer orientation and responsiveness are key affecting factors on revisit intention.

Purpose: This study analyzes the optimal operation scheme of childcare centers in Korea to maximize the quality of childcare service by determining the number of children and number of teachers. Methods: This study employs a mathematical programming methodology called 'nonlinear integer programming (NLIP)' to solve the optimization problems and compare the quality of childcare service of optimal solutions with those of present operation scheme. Results: It is very successful in obtaining the optimal solutions for alternative capacities and they guarantee the substantial improvement in the quality of childcare service. Conclusion: Though more variables should be adapted for defining the quality of childcare service robustly, it is possible to conclude that childcare centers should modify their operation scheme to improve the quality of childcare service.

The purpose of this study is to assess spatiotemporal variation of coastal water quality according to time and location changes. For this we developed numerical marine trophic index base on four water quality components (chlorophyll, suspended solids, dissolved inorganic nitrogen and phosphorus) and applied this index to the water quality data measured in the korean coastal zone for the 7-years period from 1997 to 2003. Water quality data are obtained only at selected sites even though they are potentially available at any location. Therefore, in order to estimate spatial variation of coastal water quality, it is necessary to estimate the unknown values at unsampled locations based on observation data. In this study, we used IDW (Inverse Distance Weighted) method to predict water quality components at unmeasured locations and applied marine trophic index to predicted values obtained by IDW interpolation. The results of this study indicate that marine trophic index and spatial interpolation are useful for understanding spatiotemporal characteristics of coastal water quality.

This study was undertaken to examine the degree of quality of life and to analyze the factors affecting those quality of life in middle-aged men. Method: The subjects of this study were 208 men aged by 35-55 from 3 business enterprises located in Seoul and Incheon. Data collection was conducted through the use of 5 questionnaire. Result: There were significant differences in the quality of life according to marital status, religion, educational level, number of children and total house income. A positive correlation was found between quality of life and all independent variables i.e., health promoting behaviors, health perception, social support, self-esteem and self-efficacy. Stepwise Multiple Regression Analysis revealed that the most powerful predictor was self-esteem. Self- esteem, health perception, health promoting behaviors, marriage, and social support accounted for 65% of the variance in quality of life in middle-aged men. Conclusion: All independent variables i.e., health promoting behaviors, health perception, social support, self-esteem and self-efficacy were related with quality of life in middle-aged men. Therefore it is necessary to develop the nursing intervention with these variables to increase the quality of life for middle-aged men.

This study aims to investigate the compatibility between 'quality' and 'R&D' and to ascertain what methodology can be applied. To consider the compatibility, this study discussed whether quality management can expand into R&D area in future and whether the quality management principles in ISO9000 can work well in R&D environment. Our conclusion is that the application of the quality management in R&D is valid and can serve as a new paradigm for improving R&D performance. In addition, this study divided the quality concept in R&D into several types from the viewpoints of quality definition and suggested quality methodologies for each type.
