Purpose: This paper study the effect of the quality management on the performance among the manufacturing companies awarding the Korean National Quality Award(NQA). Methods: The data for 34 manufacturing companies are surveyed by the 7-point Likert scale and empirically tested. Results: Even among the companies awarding NQA for their excellent quality management level there are significant differences in their performance by their quality management levels. In particular, leadership and human resources categories have greater impacts on the performance. Conclusion: Even though the company awarded NQA(KQMA: Korean Quality Management Award) for its excellent quality management level, it is necessary to improve the quality management level continuously. This result supports the necessity of KQGA(Korean Quality Grand Award) which is awarded for the companies which improve quality management levels significantly after awarding KQMA.

Purpose: The paper aims to measure customer experience at banks in South Korea. This study examines six factors of customer experience and identifies their impacts on customer loyalty. Methods: The collected data with surveys were analyzed by using multi-regression analysis. The measurement tools used for this study were categorized into six dimensions: Customization, Employees, Servicescape, Internet Banking, Value addition, and the Presence of other customers. Results: Customer experience has an influence on customer satisfaction: The effects of Customization, Employees, Servicescape, Internet Banking and Value addition were found. However, the presence of other customers was not significant on customer satisfaction. Interestingly, it was found that customer satisfaction made a statistically significant influence on customer loyalty. Conclusion: This study focuses on a bank sector of customer experience. Thus, six factors of measuring customer experience were found. The results of this study will predict customers' experience and also build up effective strategies for the utmost satisfaction of the customers.

Internet development requires the evaluation of secure Internet service quality. This study evaluated public Internet service quality categories and items based on the eQual program developed by Barnes & Vidgen (2006). Using a questionnaire designed to test Internet service qualities for public websites designed by The Knowledge and Information Resources Management Project, we examined 707 users and then measured the effects of service quality factors on customer satisfaction. In conclusion, we found that information quality, usability, and service interaction had a positive effect on customer satisfaction.

The purpose of this study is to analyze the effect of service quality characteristics on customer satisfaction in complex shopping mall. For the purpose of this study, we defined three service quality characteristics of complex shopping mall by correlation, harmony, synergy effect, and analyzed the effect of these quality factors on customer satisfaction. For the analysis of the data, we used exploratory factor analysis and the confirmatory factor analysis and the structural equation modeling method(AMOS 19.0). As the result of this study, we concluded that 2 of 3 service quality characteristics deeply affect on customer satisfaction in complex shopping mall, and suggest that the activation of the quality factors is needed to raise the customer satisfaction.

In recent years, Social Network Service (SNS) have increasingly gained popularity and have simplified and amplified social interaction between online users. This paper mainly discusses the user satisfaction and intention of continuous use. Based on the literature review, two hypotheses were developed and research model is built for testing. Data was collected through questionnaire survey from 260 SNS college student user. The empirical results shows a significant mediating effect for user satisfaction in the relationship between SNS' quality factors and intention to continued use.

Purpose: In this study, we suggest the systematic and comprehensive model to develop PI(Performance Indicators) of the organization or the process. Methods: The model is developed theoretically by using SIPOC(Supplier, Input, Process, Output, Customer) approach which is a tool to analyze the process and is compared with existing models to develop PI or KPI(key performance indicators); financial indicators, BSC, IPOO(input, process, output, outcome), traditional QCD (quality, cost, delivery), and IOS(input, output system). Results: The model provides more systematic method to develop PI and more comprehensive set of PI pools for all kinds of hierarchical levels of process than any other models to develop PI or KPI. Conclusion: This model will provide useful tools for the managers and the organizations who wish to develop PI.

Purpose: A Control chart is one of the important statistical process control tools that can improve processes by reducing variability and defects. Methods: In the present study, we propose the local $T^2$ multivariate control chart that can efficiently detect abnormal observations by considering the local pattern of the in-control observations. Results: A simulation study has been conducted to examine the property of the proposed control chart and compare it with existing multivariate control charts. Conclusion: The results demonstrate the usefulness and effectiveness of the proposed control chart.

Purpose: To ensure good quality munitions, we require quantitative risk management and optimal risk management of system characteristics. Methods: Failure mode and effects analysis (FMEA) is a widely used technique to assess or to improve reliability of products at early stage of design and development. Traditionally, the prioritization of failures for corrective actions is performed by developing a risk priority number (RPN). Results: This paper reestablishes an effective methodology for prioritization of failure modes in FMEA procedure. Revised evaluation criteria of RPN are devised. Conclusion: To verify the proposed methodology, it is applied to RPN evaluation for K21 infantry combat vehicle.

Purpose: The purpose of this study was to find out that the statistical method of stockpile reliability of ammunition by items can be applied to the reliability assessment of stockpile ammunition. Methods: We reviewed the statistical method of stockpile reliability of ammunition by items and verified the possibility of its application by case study. Results: We found that the statistical method of stockpile reliability of ammunition by items is very useful and effective to present the reliability of ammunition based on each item and to predict the change of the reliability in the future. The reliability of proximity fuse was about 94.5% and was influenced by manufacture's year and the difference between lot and lot more than storage period. Conclusion: The statistical method of stockpile reliability of ammunition by items can be applied to the reliability assessment of various stockpile ammunitions such as ammunition for mortar and canon.
