Journal of the Korean Society for Quality Management, volume 39, issue 4, 2011, Pages 464~479
The purpose of this study is that analyzing the causal relationship between Infra, Process and Performance of companies which are executing the Supply Chain Quality Management(SCQM) with their subcontractors and partners. Korean Standards Association(KSA) provides the Supply Chain Quality Management Model and Quality Collaboration Index for 4 years, but a few study has investigated the critical variables and their causal relationship to organizational performance. Therefore we examine the SCQM model and related index and choose the quality, human resource and risk management processes for identifying the path to organizational performance. In addition, exploratory factor analysis is conducted for figuring out the major factors among the 3 processes. Structural Equation Model are successively used for determining which characteristics of the infra and processes are the most critical variables to performance. The data was collected from KSA and composed of 52 companies and 346 their partners. The result shows that risk management process has no significant effect on the organizational performance and pre-production process collaboration.
A Spare Ordering Policy for Preventive Replacement with Repair
Lim, Sung-Uk ; Park, Young-Taek ;
Journal of the Korean Society for Quality Management, volume 39, issue 4, 2011, Pages 480~485
This paper presents a spare ordering policy for preventive replacement with minimal repair. To analyze the ordering policy, the failure process is modeled by a non-homogeneous Poisson process. Introducing the ordering, repair, downtime, replacement costs and salvage value, we derive the expected cost effectiveness as a criterion of optimality when the lifetime and lead times for the regular and expedited orders are generally distributed random variables. It is shown that, under certain conditions, there exists a finite and unique optimum ordering time which maximizes the expected cost effectiveness. A numerical example is also included to explain the proposed model.

Now, the Korean consumer market enters into the stage of the advanced country type's mature consumption, totally different from the consumption of the past, and among these changes, the quality enhancement and bipolarity of the consumption show clearly the rising trends together with the popularization of the Masstige Brand due to the big expansion of the quantity. Unlike the old luxury brands, available only to the rich people in the past, the Masstige Brands are tagged with reasonable and affordable prices and provide the consumers with the good quality and convenient sensibilities as good as the old famous brands, which have become new high-class brands for the middle-income class. As the middle-come people get more income and are eager to live a better life, the Masstige Brands rise fast. Therefore, the study is aimed at examining the consumer-related factors affecting the purchase of the Masstige Brands on the basis of the fashion brands. In other words, the factors affecting the formation of the positive purchasing intentions of consumers will be verified by examining the influence of such factors, as the consumer value, brand charisma, attitude and loyalty, the variables affecting the purchasing intentions of the Masstige Brands, which are found out through the proceeding researches. As the result of the verification on the assumption, it is found out that the consumer value has a positive influence on the brand charisma. Also, it is found out that the consumer value has a positive influence on the brand attitude. And, it is discovered that the brand charisma has a positive influence on the brand loyalty. It is shown that the brand attitude has a positive influence on the brand loyalty. Lastly, it is indicated that the brand loyalty has a positive influence on the purchasing intention of consumers.

Lim, Yong-Bin ; Cho, Ho ; Kim, Yoing-Il ;
Journal of the Korean Society for Quality Management, volume 39, issue 4, 2011, Pages 500~506
Evolutionary operation (EVOP) proposed by Box(1957) is a method for continuous monitoring and improvement of a full-scale manufacturing process with the objective of moving the current operating conditions toward the better ones. EVOP in experiments with mixtures consists of screening vital few components and making small changes in the current operating condition by making small increments in the proportion of the screened component. In this paper, how to determine operating conditions in EVOP in experiments with mixtures around the current operating condition is proposed. The proposed methods are illustrated with the simulated data based on the well known flare experimental data described by McLean and Anderson(1966).

Journal of the Korean Society for Quality Management, volume 39, issue 4, 2011, Pages 507~515
MIL-HDBK-217 has played a pivotal role in reliability prediction of electronic equipments for more than 30 years. Recently, RIAC developed a new methodology
which officially replaces MIL-HDBK-217. Sensitivity analysis of the 217Plus component models to various parameters has been performed and meaningful observations have been drawn in this study. We first briefly reviewed the
methodolog and compared it with the conventional model, MIL-HDBK-217. We then performed sensitivity analysis
component models to various parameters. Based on the six parameters and an orthogonal array selected, we have performed indepth analyses concerning parameter effects on the model. Our result indicates that, among various parameters, operating temperature and temperature rise during operation have the most significant impacts on the life of a component, and thus a design robust to high temperature is the most importantly required. Next, year of manufacture, duty cycle, and voltage stress are weaker but may be significant when they are in heavy load conditions. Although our study is restricted to a specific type of diodes, the results are still valid to other cases. The results in this study not only figure out the behavior of the predicted failure rate as a function of parameters but provide meaningful guidelines for practical applications.

The AS9100 standard builds upon the ISO 9001:2000 quality management system requirements(in their entirety) and defines additional quality management system requirements for the aerospace industry. The 9100 standard on quality management system requirements is intended to be used at all levels of the supplier chain. The International Aerospace Quality Group has released a revision to 9100 for the aviation, space and defense industries. This change aims at improvement on quality, schedule and cost performance by adopting new requirements based on stakeholders' needs. This paper is to review how the AS9100 QMS Requirement has been established and improved, and to communicate the significant changes from AS9100, Rev. B to Rev. C focusing on reasons for revisions. The proposed schedule and considerations on the transition of the changes to Rev. C are also dealt with in this paper.

The importance of service industry in national economy is getting increasing due to current trend of aging society and increasingly desire for better quality of life. However, the level of labor productivity in domestic service industry is lower than Japan and Germany that are typically strong in manufacturing industry. Difficulty of process control and measurement in accordance with variability and intangibility which are features of service industry, is considered as the cause of this poor labor productivity in Korea. This study aims to present managerial implications by calculating sigma levels on branch bank service quality and suggesting the quality dimensions of banks can be checked through a gap comparison between the sigma level on service quality in the whole banks and service quality in each bank. Quality level presented by the KS-SQI is applied to the measurement method that Yoo Han Joo and Song Kwang Seok suggested in 2006. Spss18.0 is used as an analysis tool. As a result of factorial analysis, 7 dimensions of service quality in KS-SQI can be divided into new 3 dimensions of service quality. This study also suggests that width and number of questions in previous questionnaire shall be extended. The whole of the bank service quality level is evaluated 3 sigma. The research help banks to figure out their service quality level through gap comparison objectively.
