Improvement of Environmental Management in Small and Medium-Sized Firms through the Implementation of Environmental Management System
Journal of the Korean Society for Quality Management, volume 32, issue 2, 2004, Pages 1~14
As environmental issues have been become critical concerns of business, many domestic small and medium enterprises(SME's) are rapidly accepting environmental management systems(EMS) that confirm ISO 14001 guidelines. The purpose of this paper is to present the results of an empirical study carried out on a sample of certified SME's with the aim of identifying obstacles encountered in adopting ISO 14001 standards and the impact of environmental systems on corporate performance after implementation of the ISO 14001 registration process. Data from this study show that the vast majority of respondents reported environmental improvements related to the implementation of an ISO 14001 EMS, especially in the area of employees' participation of the environmental management and responsibilities for reducing negative impacts, energy and resource conservation, materials reuse, and raising top management commitment. The greatest obstacles for implementing the ISO 14001 standard are lack of cooperation and a scarcity of resources such as personnel, money, and time. Results of this study serve as a reference point understanding the problems in the implementation of ISO 14001 in other small and medium firms.
A Preliminary Study on the Satisfaction of Mobile Internet Service Usage
Journal of the Korean Society for Quality Management, volume 32, issue 2, 2004, Pages 15~23
This study investigates the customer satisfaction based on the various levels of many factors such as age, sex, period, motive, preference between wired and mobile service, frequency, and time. Customer satisfaction is measured by 13 dimensions. MANOVA reveals that preference between wired and mobile commerce service, mobile service frequency, mobile e-mail service frequency, wired Internet usage frequency, and mobile Internet usage time have a significant effect on the overall satisfaction. Transmission speed, fare, and ease of operation of mobile Internet service turn out to be improved for better customer satisfaction, the IMT-2000 service in particular.
A Study on the Effects of Flow on Customer Purchase Intention in Internet Shopping Malls
Journal of the Korean Society for Quality Management, volume 32, issue 2, 2004, Pages 24~36
In order for electronic commerce to be successful, it must have a theoretical framework that considers the characteristics of the internet user who are consumers in the cyber space and impacts their purchase intentions. We were able to obtain participations of 316 people, and derived statistics by means of SPSS/PC version 10.0 and Amos 4.0 statistics package. We found that, the higher the degree of skill and the sense of challenge, the level of involvement and perceived service quality increased. And the degree of skill has a negative influence on awareness of perceived risk than the sense of challenge. Perceived service quality, perceived risk and involvement has a influence on purchase intentions.
The Effect of the Organizational Leadership and Corporate Culture Types, ISO 9001:2000 System, the Quality Culture Formation on the Corporate Performance
Journal of the Korean Society for Quality Management, volume 32, issue 2, 2004, Pages 37~58
This study examines the effects of ISO 9001:2000 Quality Management System(QMS). Before accrediting it, it is affected by the top management leadership and corporate culture. After finishing the accreditation, some companies form quality culture, but some companies do not. That affects the corporate performance. If quality culture forms, companies performance will be good. But if not, companies performance will be bad. The accreditation of ISO QMS is not the end goal for the companies but forming the quality culture will enhance the corporate performance.
A Study of Developing the Evaluation Tools of International Airport′s Service Quality in Korea
Journal of the Korean Society for Quality Management, volume 32, issue 2, 2004, Pages 59~76
It has been regarded as important in both academic and practical issues how to evaluate service quality. In addition international traveling will be growing due to increasing income and globalization. Thus, it is very important to measure the international airport's service quality properly. This study was conducted to identify the service quality factors which are utilized to measure international airport's service quality. According to the statistical analyses' results of this study, seven service quality factors and thirty two measurement items were found to evaluate international airport's service quality. They are some different from those which PZB(1988b) identified to measure service quality. This result implies that it is necessary to find the service quality factors reflecting the unique characters of the service organization when measuring service quality of a service organization.
A Model of Evaluating the Efficiency of Container Terminals for Improving Service Quality
Journal of the Korean Society for Quality Management, volume 32, issue 2, 2004, Pages 77~92
It is difficult but very necessary to measure the productivity of container terminals as logistics service provider. It is meaningful to find the appropriate inputs and outputs of the logistics service delivery systems and to measure the relationship between these inputs and outputs. This study proposes a model of evaluating the efficiency of container terminals. The evaluation consists of three phases. First, DEA(Data Envelopment Analysis) phase, determines the efficiency score and weights of DMUs(Decision Making Unit). This phase performs through four steps : selection of DMU, selection of DEA model, determination of input and output factors, calculation of efficiency score and weights for each DMU. Secondly, CEM (Cross Evaluation Model) phase, is to calculate the cross-efficiency scores of DMUs. This phase performs through three steps: selection of CEM, determination of cross-efficiency score for each DMU and development of cross-efficiency matrix. Finally, average cross-efficiency analysis phase is to compute the average cross-efficiency score. The proposed model discriminates among DMUs and ranks DMUs, whether they are efficient or inefficient.

Journal of the Korean Society for Quality Management, volume 32, issue 2, 2004, Pages 93~108
The purpose of this research is to summarize the methodological issues in internet survey and to suggest personalized internet survey system using data mining technique for enhancing the survey quality of internet survey as well as utilizing the benefit of interactive multimedia factors of internet survey. The data mining technique used in this paper is Case Based Reasoning for adopting individual design preference affecting survey quality. For achieving the research purpose, two surveys, pre & post survey, were performed. Pre survey was done for implementing CBR database to find individual index affecting survey quality and post survey was used for measuring the peformance of personalized internet survey system. The result shows that the survey quality of personalized web survey system is better than generalized web survey system.
A Study on the Service Quality Level and Switching Barriers in the Retail Industry -Comparing Department Store with Discount Store-
Journal of the Korean Society for Quality Management, volume 32, issue 2, 2004, Pages 109~131
This research tried to clarify the impact of service quality on the customer satisfaction, customer retention and switching barriers in the competitive structure between department store and discount store. We measured the level of service quality by using the methodology which had been adopted in the service quality research area. Using the internet survey method, we gathered data from 750 consumers of each industry. We used various analysis methods such as the regression analysis, t-test, and hierarchical regression analysis. The results reveal different patterns in the two sectors in the retail industry with respect to switching barriers. We conclude that switching barriers play an important role in consumer satisfaction and retention.
The Z-CUSUM Control Chart for the Process with Recurring Cycles or Frequent Small Shifts
Journal of the Korean Society for Quality Management, volume 32, issue 2, 2004, Pages 132~153
CUSUM control charts are widely used to monitor processes with small shifts. CUSUM control charts are, however, less effective in detecting for recurring cycles or frequent small shifts in the processes. With Shewhart control charts, we have applied the variety of run rules to check the stability of process in addition to the situations that some points fall outside the control limits. In this paper, we propose the Z -CUSUM control chart for monitoring the process with recurring cycles or frequent small shifts by use of the zone concept as like the Shewhart control charts.
Implementation of TOC/DBR under Six Sigma environment
Journal of the Korean Society for Quality Management, volume 32, issue 2, 2004, Pages 154~167
The TOC/DBR and Six Sigma are the most attention-getting concepts for managing manufacturing companies in Korea. Using the ideas and methods of the TOC/DBR, companies can achieve a large reduction of work-in-process and finished-good inventories, significant improvement in scheduling performance, and substantial earnings increase. The Six Sigma approach derives the overall process of selecting the right projects based on their potential to improve performance metrics and selecting/training the right people to get the business results. These two concepts have different backgrounds and different viewpoints for production systems. So, if the two concepts collaborate each other, the synergy effects to innovate production systems can be expected. This paper proposes a new approach to implement the TOC/DBR concepts in production systems. This approach uses some concepts of Six Sigma which stresses educations, project approaches (step by step procedure using a Roadmap), and improvement philosophy.
Design and Implementation of a Web-based Expert System for the Total Quality Management
Journal of the Korean Society for Quality Management, volume 32, issue 2, 2004, Pages 168~190
In these days of world-wide business environment, the characteristics of quality management are variety, specialty, decentralization, totality, etc. Thus nowadays quality management is demanded to incorporate these new concepts. We propose a web-bused distributed expert system for this purpose. The system consists of four expert systems for design of experiment, acceptance inspection, statistical process control and reliability management corresponding to design quality, incoming-material quality, manufacturing quality and usability quality, respectively, throughout the total product life cycle. Each distributed expert system at the horizontal level in the hierarchy carries out its own quality jobs independently. At the lower level in the hierarchy there is an expert system for measurement analysis to provide reliable data, and at the upper level, an expert system for total quality management to coordinate, integrate and make final decisions. A prototype has been developed and its application is presented.
A Design of Control Chart for Fraction Nonconforming Using Fuzzy Data
Journal of the Korean Society for Quality Management, volume 32, issue 2, 2004, Pages 191~200
Using the p chart is not adequate in case that there are lots of data and it is difficult to divide into products conforming or nonconforming because of obscurity of binary classification. So we need to design a new control chart which represents obscure situation efficiently. This study deals with the method to performing arithmetic operation representing fuzzy data into fuzzy set by applying fuzzy set theory and designs a new control chart taking account of a concept of classification on the term set and membership function associated with term set.
Problems of Special Causes in Feedback Adjustment
Lee, Jae-June ; Cho, Sin-Sup ;
Journal of the Korean Society for Quality Management, volume 32, issue 2, 2004, Pages 201~211
Process adjustment is a complimentary tool to process monitoring in process control. Process adjustment directs on maintaining a process output close to a target value by manipulating another controllable variable, by which significant process improvement can be achieved. Therefore, this approach can be applied to the 'Improve' stage of Six Sigma strategy. Though the optimal control rule minimizes process variability in general, it may not properly function when special causes occur in underlying process, resulting in off-target bias and increased variability in the adjusted output process, possibly for long periods. In this paper, we consider a responsive feedback control system and the minimum mean square error control rule. The bias in the adjusted output process is investigated in a general framework, especially focussing on stationary underlying process and the special cause of level shift type. Illustrative examples are employed to illustrate the issues discussed.
