Journal of the Korean society for quality management, volume 34, issue 2, 2006, Pages 1~11
This paper is related to the effect analysis of certification of ISO 9000 Quality Management System. We collect and analyze the field data of certification costs and profit from companies that are located at southeast area in Korea. The effect analysis is based on the type and scale of companies. We use defective rate and inventory turnover rate as the criterion of positive effect after certification. As a result, we may conclude that the certification of ISO Quality Management System gives companies positive effects.
Economic Selection of the Optimal Process Mean Using Sequential Inspection to Reduce the Effect of Measurement Errors
Park, Hwan-Su ; Chang, Young-Soon ;
Journal of the Korean society for quality management, volume 34, issue 2, 2006, Pages 12~21
This paper considers the problem of selecting the most profitable process mean for production processes where measurement errors exist in inspection systems. For such situations, a sequential inspection procedure is proposed to reduce measurement errors. The decision to accept, reject, or take an additional inspection of an item is made at every measurement point until the number of repeated measurements reaches its upper bound. An expected profit model is constructed and the optimal process mean, the cut-off values, and the upper bound of the number of repeated measurements are obtained when accepted(rejected) items are sold at regular(reduced) price. A numerical study is performed to investigate the performance of the proposed procedure.

Journal of the Korean society for quality management, volume 34, issue 2, 2006, Pages 33~47
This study was designed to examine the casual relationships among trust evaluation factors, trust, customer satisfaction, and re-use intention in the P2P file sharing service. We applied structural equation model to test the hypotheses and research model. As a result of this study, trust evaluation factors affect trust and customer satisfaction and both of trust and customer satisfaction affect re-use intention respectively and significantly. Also trust affects customer satisfaction significantly. Specifically, trust was empirically confirmed as one of the important factors preceding customer satisfaction and re-use intetion in the P2P file sharing service. Therefore, this study shows that trust is important factor that P2P companies have to emphasize to raise user satisfaction and performance.
An Effect of Service Quality Factors on Customer Satisfaction in Infant Education Institutes : Centered on the Comparison of Kindergartens and Daycare Centers
Choi, Sung-Yong ; Kwon, Mi-Young ;
Journal of the Korean society for quality management, volume 34, issue 2, 2006, Pages 48~67
In this study, an investigation was done into service qualify factors of infant education Institutes, after which a positive verification was made in the relation of cause and effect between service quality, service value and customer satisfaction. Based on this verification, strategies were presented for plans to improve the service quality of infant education. In addition, identification was made into factors that affect customer satisfaction, re-registration intention and recommendation to others in putting forward service operational strategies for infant education institutes and making a comparative analysis on kindergartens and daycare centers.
Application of Six-sigma Management Innovation in Telecommunication Service Industry : A Case of Applying Six Sigma in KT
Lee, Kee-Chul ; Ro, Tae-Soek ;
Journal of the Korean society for quality management, volume 34, issue 2, 2006, Pages 68~76
It is generally thought that the quality management and the six-sigma management innovation are not applicable to service industry, which might be derived from some differences between service and manufacturing industries. However, both are substantially alike in some intrinsic attributes. KT is leading the quality management and the six-sigma innovation activities in service industry, especially among telecommunication companies in Korea. Six sigma management innovation has been fostered in KT within short period of time and played an important role in helping KT privatized successfully. The successful cases of six sigma innovation activities in KT could be introduced to other Korean companies in service industry. Five key factors for the success of six-sigma innovation activities are suggested, The hidden factory in all the fields of company should be eliminated. Six-sigma projects need to be connected with the company strategy. The project should be carried out intensively in a short time. The innovation activities in the field need to be integrated. The best practice of six-sigma should be disseminated in the field.
Replication of Internal Service Quality Battery : The Assessment of Its Reliability and Validity
Kang, Gi-Du ;
Journal of the Korean society for quality management, volume 34, issue 2, 2006, Pages 77~97
Internal marketing has been suggested as the approach for service organizations to be service-and customer-oriented; and the issues of internal service quality has been one of topics widely discussed in the internal marketing literature. While previous studies have attempted to develop the instrument assessing the internal service quality, ISQB(internal service Quality battery) developed by Kang et al.(2002), compared to other instruments have received some attention given its rigorous approach to measure the internal service quality. However, it has been noted that the validity of ISQB does not appear to be thoroughly examined while the reliability of the instrument seems to be secured. The current study attempts to readdress the psychometric properties of ISQB through the replication of the instrument. The empirical testing including confirmatory factor analysis and correlational analyses show that the instrument is reliable and valid in terms of its discriminant and nomological validity.
An Empirical Study on the Effectiveness of ISO 9000/14000-Registered Companies in Korea
Lee, Gun-Hee ;
Journal of the Korean society for quality management, volume 34, issue 2, 2006, Pages 98~106
ISO 9000/14000 certification is increasingly becoming 'a passport for business' in the marketplace. However, its effectiveness of both internal and external performance is highly controversial. In this study, empirical research is performed to identify the main objectives and expectation of ISO 9000/14000 and evaluate the effectiveness of certification. Our empirical results show that there are big differences between small and medium companies and large companies for the effectiveness of ISO 9000/14000. Especially, ISO 14000 certification provides very low effectiveness for the small and medium companies in Korea.

In spite of the increase of the necessity and the interest regarding the SCM in practical business, it is difficult to judge the whole situation of the SCM because the research remain fragmentary as compared with the huge and complicated concept of the SCM. So this study defines dimension of SCM practice and measurements of SCM performance. Through an extensive literature review, the study Identifies seven dimension of SCM practice(partnership, usage of IT tools, information sharing and information quality), five measurements of SCM performance(supply chain flexibility, supply chain integration, customer responsiveness, supplier performance, and partner relationship). Five hypotheses were formulated for the relationship between SCM practice and SCM performance. The important relationships to be tested include ; (1) the direct impact of usage of IT tools on the partnership (2) the direct impact of partnership on the information sharing and information quality (3) the direct impact of SCM practice on the performance of SCM, (4) A moderating effect of top management support on the relationship between SCM practice and SCM performance.
Analysis and Usage of Computer Experiments Using Spatial Linear Models
Park, Jeong-Soo ;
Journal of the Korean society for quality management, volume 34, issue 2, 2006, Pages 122~128
One feature of a computer simulation experiment, different from a physical experiment, is that the output is often deterministic. Moreover the codes are computationally very expensive to run. This paper deals with the design and analysis of computer experiments(DACE) which is a relatively new statistical research area. We model the response of computer experiments as the realization of a stochastic process. This approach is basically the same as using a spatial linear model. Applications to the optimal mechanical designing and model calibration problems are illustrated. Algorithms for selecting the best spatial linear model are also proposed.

In the advance of computer technology, it is possible to keep all the related informations for monitoring equipments in control and huge amount of real time manufacturing data in a data base. Thus, the statistical analysis of large data sets with hundreds of thousands observations and hundred of independent variables whose some of values are missing at many observations is needed even though it is a formidable computational task. A tree structured approach to classification is capable of screening important independent variables and their interactions. In a Six Sigma project handling large amount of manufacturing data, one of the goals is to screen vital few variables among trivial many variables. In this paper we have reviewed and summarized CART, C4.5 and CHAID algorithms and proposed a simple method of screening vital few variables by selecting common variables screened by all the three algorithms. Also how to develop a logistics regression model on a large data set is discussed and illustrated through a large finance data set collected by a credit bureau for th purpose of predicting the bankruptcy of the company.
