본 연구는 6시그마 경영기법의 건설업에 대한 적용 성과를 분석하고자 수행하였다. 이를 위하여 S 건설업체의 조직 및 인력별 6시그마 적용 프로젝트의 품질비용을 분석하고, S 건설업체의 임직원들을 대상으로 6시그마 경영에 대한 설문조사를 실시하였다. 위와 같은 목적과 방법에 따라 진행된 본 연구의 결과를 요약하면 다음과 같다. : 1) S 건설업체의 6시그마 경영기법의 도입은 03년과 04년에 걸쳐 258건의 프로젝트를 수행하면서 품질비용 절감효과를 발생시켰다. 또한, S 건설업체는 6시그마 적용 전 시그마 수준이 업무 분야별 평균 2.8이었으나, 적용 후 평균 3.6으로 향상되었다. 특히, 공사 관리 분야는 적용 전 1.3시그마에서 적용 후 2.6시그마로 매우 높은 향상율을 보였다. 2) 6시그마 경영활동에 대한 업무수행 기대성과에 관한 분석결과 대다수의 직원들은 6시그마 경영이 비용절감 효과가 있으며, 품질향상에 도움이 되는 것으로 인식하고 있었다. 그러나 현 시점은 S 건설업체에 있어 6시그마 경영기법의 도입 초기단계이므로 업무처리의 효율성에는 큰 효과를 보이지 않는 것으로 조사되었다.

This research has been conducted in order to assess the effects on quality management factor of the construction sites. 30 companies abiding by the 'construction industry law' and 32 companies abiding by the 'housing construction promotion law' have been researched in areas of quality-management environment, quality-management understanding, quality-management education on construction field, quality-system and quality-improvement. This construction quality factors are to realized the anticipated results not only quality level's increasing, but also company's confidence, competitiveness. We were able to obtain participations of 62 questionnaire, and derived statistics by means of SPSS/PC version 10.0. In this study, we find the bottleneck factor for promotion and upgrade quality management factor of the construction sites and suggest a way out of difficulties.

This study describes the creation of a scale to measure standardization for service encounter process. Measuring standardization of service encounter process is devided into manual level and action level. We investigate the relative impact of process standardization about service quality, job satisfaction and labor productivity. Our findings indicate that action level of service encounter process standardization is more important than manual level, and its process standardization positively affects service quality, job satisfaction and labor productivity positively.

Purpose: This article aims 1) to propose improvement directions of the certification by recognizing the quality management practices based on the analysis of the audit results of the military contractors and 2) to suggest some ideas on quality audit planning preparation to help the government quality assurance representatives. Methods: Based on the nonconformity report of the defense quality management system (DQMS) requirements, frequently occurring requirement components are found and summarized. Three hypothesis testings are executed to check whether the maturity levels of the quality management systems are influenced by the company size, weapon tye, and company type, regarding the nonconformity frequency as dependent variable. Results: Nonconformity occurs most frequently in the order of product realization, measurement analysis and improvement, management responsibility, resource management, and quality management system. Nonconformity reduces when the company size increases, for the guided weapons, and in the defense companies. Conclusion: Since small-sized companies are inferior to larger companies with respect to the DQMS maturity level, more support should be provided to these small-sized companies which produce military supplies.

This paper deals with preventive replacements models for the item whose failures are dependent on their wear level. When measuring the item wear level is very costly, it may be economical to use substitutive characteristics that are correlated with the item wear level and relatively inexpensive to measure. In this paper, replacement policies based on such substitutive characteristics are proposed. The optimal level of substitutive characteristic to replace the item, which minimizes total cost, is obtained. Some numerical examples are also given.

We this study investiged the level of perception such as construction quality-related systems according to the subject of construction work. The results of the recognition moisture survey showed a high response rate in the order of construction companies and supervisors. The result of the system's level of understanding was low at 3.6 points for the orderer and contractor. In addition, in recognition of the effectiveness of the quality management system, the contractor showed a somewhat negative perception than other targets.

Total quality management (TQM) is regarded as a tool for improving the competitiveness not only for a manufacturing sector, but also for a service sector, The objective of this paper is to classify TQM education by management level, to identify how TQM education be implemented by the type of industry, to analyze the relationship of TQM education with business performance, and finally to analyze the difference between companies with ISO certification and those without ISO certification in terms of TQM education. The findings suggest that there was a significant difference between manufacturing and service sector in TQM education level. Also, the relationship of TQM education with business performance was partially correlated. Finally there was no significant difference between companies with ISO certification and those without ISO certification in terms of TQM education.

Purpose: This study aims to propose Kano-SERVQUAL integrated approach as an effective tool for evaluating auto service quality attributes to enhance the use of SERVQUAL. Methods: The Kano-SERVQUAL survey was conducted to evaluate customer perception for 28 auto service quality attributes which were obtained from auto service expert in 'H' company. The correlation analysis of SI(Satisfaction Index), DI(Dissatisfaction Index) and expectation values are conducted in this study. Results: The 28 auto service quality attributes are classified into attractive attributes and one-dimensional attributes. The results of this study show that the correlations between the customers' expectation values and DI is strongly positive correlation with 1% significance level, expectation values and SI is negative correlation with 10% significance level. Conclusion: The results show that the purposed Kano-SERVQUAL integrated approach provides a deeper understanding of service quality attributes in that it distinguishes the customers' expectation values between highly expected attributes(e.g. must-be attribute) and less expected attributes(e.g. attractive attribute).

Among service industries of knowledge based economic era, the roles of educational service field are becoming more important and standard of educational service makes a direct effect on economic development and social growth. Therefore, accurate measurement of service quality is the most important assignment and the measurement of the service quality remains difficult assignment. So, this researcher classified quality attributes applying weighted value and found potential satisfaction level(PSL) and potential customer demand improvement index(PCDI) for trainees participating in national manpower business so as to suggest measurement of service quality and easiness of use and then, calculated satisfaction position and opportunity cost by quality factor with Taguchi's loss fraction. And, improvable satisfaction level was measured, opportunity cost by degree of customer dissatisfaction was quantitatively measured, and a model that can indicate with economic factors was suggested. In addition, methodology of measuring quality cost that can be reduced by quality improvement and direction of strategic decision-making for deciding items to be improved preferentially were suggested with qualitative index that can indicate the degree of customers' dissatisfaction by loss.
