Research on grading the quality level and developing the comparability index of the national statistics
Shim, Kyu-Ho ;
Journal of the Korean society for quality management, volume 38, issue 2, 2010, Pages 150~160
Statistics Korea has been diagnosis national statistics every year since 2006. They diagnosis over 200 kinds of national statistics. They have 7 quality dimension used for quality diagnosis. That is relevance, accuracy, Timeliness, Comparability, Coherence, Accessibility. Since we are interest in how well they produce national statistics, comparability has become the most important dimension recently. In this reason, Statistics Korea try to rating quality level and development comparability index for national statistics. This paper propose the practical method of grading the quality level and developing the comparability index of the national statistics.

Ku, Hee-Jin ; Park, Young-Taek ;
Journal of the Korean society for quality management, volume 38, issue 2, 2010, Pages 161~170
Diffusion of e-learning has been accelerated according as the convenience and effectiveness have been increased rapidly due to the advancement of information technology. However, there has been few studies on systematic evaluation of its performance. SERVQUAL model was applied to evaluate the service quality of a 100% on-line lecture opened in a major Korean university. Two classes, one for 71 undergraduate students, the other for 79 graduate students, were opened for the lecture. The gaps between the expected service and the perceived service scores were compared with respect to sex, age, and e-learning experience. Although the gap score of male and female students were not different significantly, the gap scores among the other comparative groups were different. The perceived score of the older group with more than thirty ages was lower than that of the younger group. It seems that the older group evaluated the score based on the practical use of the subject since they are part-time students with jobs. Also, the perceived score of the group with previous e-learning experience was higher than that of the group with no e-learning experience. It seems that the experienced group evaluated it compared with the previous e-learning satisfaction. As it might be expected, the groups with higher perceived scores had stronger intention to recommend the e-learning lecture to other students.

Jang, Dae-Heung ;
Journal of the Korean society for quality management, volume 38, issue 2, 2010, Pages 171~179
Pearn et al.(2002) supposed the
multiple process performance analysis chart. This chart displays multiple processes with the process variation and process departure on one single chart. But, this chart can not display the distribution of the process variation and process departure and is inappropriate for processes with non-normal distributions. With bootstrapping method, we can display the distribution of the process variation and process departure on the
multiple process performance analysis chart.

Kang, Bun-Kyu ; Lim, Tae-Jin ;
Journal of the Korean society for quality management, volume 38, issue 2, 2010, Pages 190~201
This research proposes a method for designing VSI (Variable Sampling Interval) control charts with supplementary run rules. The basic idea is to apply various run rules and the VSI scheme to a control chart in order to increase the sensitivity. The sampling process of the VSI run rules chart is constructed by Markov chain approach. A procedure for designing the VSI run rules chart is proposed based on Lorenzen and Vance's model. Sensitivity study shows that the VSI run rules charts outperform the FSI (Fixed Sampling Interval) run rules charts for wide range of process mean shifts. A major advantage of the VSI run rules chart over other charts such as CUSUM, EWMA, and adaptive charts is it's simplicity in implementation. Some useful guidelines are proposed based on the sensitivity study.
Some Suggestions to Improve the Korean Quality Awards Systems through the Comparison among Asian Countries' Awards Systems
Lee, Kwan-Suk ; Chung, Kyu-Suk ;
Journal of the Korean society for quality management, volume 38, issue 2, 2010, Pages 202~211
Many Asian countries operate the national quality award systems. Most of the evaluation criteria of the award systems are generally based on the MalCom Baldrige National Quality Award System of U.S.A. which started since 1987. But their operation systems for awards are different by countries. Comparing the differences among them can give a good benchmark for Korean Quality Award systems. There are poor empirical results that the Korean Quality Awards systems improve the performances of the organizations awarded. This paper proposes some suggestions for the effective operations of Korean quality award systems through the comparison among Asian countries' awarding systems.

After the introduction of Volume-based Waste Fee System for municipal wastes, the disposal of food wastes became an issue in society. As this reason, recycling food wastes facilities play an important role such as converting of food waste into animal feed or composting of food waste. Therefore, there is need of efficiency measurement of the facilities to reduce the inefficiency of factors. The purpose of this paper is to make a reasonable suggestion for the improvement of inefficient recycling food wastes facilities. This paper assesses the relative efficiency of recycling food wastes facilities by examining the relationship between inputs and outputs in 41 facilities using data envelopment analysis(DEA). The result shows that 4 facilities whose values of CCR efficiency are 1, and 10 facilities whose values of BCC efficiency are 1, RTS indicates IRS of 17 facilities and CRS of 6 facilities.

This study was preformed to analyze the effect of ISO 26000(Global Standard on Social Responsibility(SR)) establishment and implementation on Korean Industries, and to take proper responsive measures as the results. ISO 26000 Global Standard was begun to prepare the establishment from 2003, and now being ended to be implemented as the effective SR Global Standard. If the ISO 26000 is published, almost countries must prepare the suitable process to implement its contents. But, many organizations involving the government and the enterprises in Korea have not the complete informations and knowledges about the ISO 26000 Global Standard and the implementation processes. This is serious problem. So, this study was aimed and performed to cope with this problem. In this study, the effect analysis of the establishment ISO 26000 Global Standard on Korean Economy and the industries will be performed, and the effective measures to prepare for its implementation will be taken. Especially the measures of the individual company to this situation will be discussed.

Journal of the Korean society for quality management, volume 38, issue 2, 2010, Pages 248~260
Customer satisfaction is an ever-growing concern of management throughout the world. To find the way to increase customer satisfaction, we must understand customer requirements. Kano distinguishes between three types of product requirements (;must-be, one-dimensional, attractive requirement) which influence customer satisfaction in different ways when met. Timko has developed customer satisfaction(CS) coefficient based on Kano model. The CS coefficient is indicative of how strongly a product feature may influence satisfaction. In this paper, potential customer satisfaction improvement(PCSI) index was proposed using Kano model and CS coefficient. The PCSI index represents how much a product feature can increase the degree of customer satisfaction when the product feature is fully fulfilled. In order to explain the meaning of PCSI index, a case study for cellular phones is done. It is also discussed how to use the index strategically.

Journal of the Korean society for quality management, volume 38, issue 2, 2010, Pages 261~275
The purpose of this study is to empirically analyze the productivity change of the 10 Single PPM Certification Company in the 3 Industry(Electronics, Motor-Parts, Machines). In this study, Productivity change over the time in Korean small and medium sized firms in the 3 industries by the bootstrapped Malmquist Productivity Index(MPI). The traditional Malmquist Productivity Index(MPI) and Data Envelopment Analysis(DEA) Models have not only bias but also lack statistical confidence intervals. they could lead to wrong evaluations of the efficiency and productivity scores. In this paper, DEA and a MPI are combined with a bootstrap method in order to provide statistical inferences that analyze the performance of the Single PPM Certification Company. The data cover the period between 2004 and 2007. The result of this paper reveals : 1) The Electronics Industry had productivity effect of 17%, but there was not direct effect for other Industries(Motor-Parts, Machines). 2) average productivity Progress of the 7DMU(Electronics), 1DMU(Motor-Parts) and none(Machines).

Journal of the Korean society for quality management, volume 38, issue 2, 2010, Pages 276~283
ISO 9000 family of standards are consisted of four international standards for implementing and operating effective quality management systems. They are interrelated and together form a coherent set of quality management system standards. ISO 9000, one of the standards, contains quality management principles, which is asserted to form the basis of other standards within the family. ISO 9001 is another standard within the family and contains requirements for quality management systems. This paper shows how the quality management principles of ISO 9000 are related with the requirements of ISO 9001.
