Recently, client requirements concept is an important issue related to many effects of firms. Especially, if we think that apartment is given a great deal of national construction industry, it is requested that we should try to improve apartment quality with various methods of client requirements survey and reflecting those on apartment project. The technique searching and applying client requirements to apartment project is requested for that and ROQ(Return On Quality) process connected to QFD(Quality Function Deployment) is a technique which is used in manufacturing industry and help to make money by rising client satisfaction with searching clients requirements, and applying this to quality improvement program. In this study apartment quality management development is suggested through using ROQ process. For this customer interview research and FGI(Focus Group Interview) was carried out and clients requirement was analyzed with this. Then quality improvement program applicable to developing a new apartment product was established with specialist monitoring. A new apartment quality management development plan is prosed with this process.

오늘날 우리나라 기업들이 정부가 경제운용방식을 민간주도의 경제운용방식으로 전환하겠다는 정부시책에 따라 총합적품질관리(TQC)를 정착화하여, 기업의 재무구조를 개선하고, 생산성 및 품질향상을 통하여 국제경쟁에 이기기 위하여, 전국적으로 TQC 정착화운동을 활발히 전개하고 있음은 주지의 사실이다. TQC의 진수를 이루고 있는 것이 통계적품질관리(SQC)이므로 통계적방법의 공업에의 응용면을 찾아보는 것은 SQC 기법의 활용도를 찾아보는 것과 동일하다고 본다. 공업통계의 활용은 생산성향상과 공산품의 품질향상에 직결되므로 차제에 우리나라 기업이 어느 정도 통계교육을 받고 있고, 어느 정도 활용하고 있나를 파악한 후, 그것을 분석하고, 개선대책을 내놓는다면 커다란 의의가 있다고 생각되나, 필자의 제한된 경험과 제한된 자료, 제한된 시간 관계상, 그렇게하지 못함을 송구스럽게 생각한다. 본논문은 필자의 한국공업표준협회의 품질관리교육, 품질관리대상심사, 품질관리분임조경쟁대회심사 등을 통한 제한된 경험과 자료를 가지고, 한국공업통계이용현황에 관하여 기술한 것이다. 첫째로 우리나라 기업의 공업통계교육현황을 살펴보고, 둘째로 우리나라 기업이 공업통계를 제품의 개발단계에서 생산단계, 판매단계에 이르기까지 어떻게 활용하고 있는지 그 정도를 살펴보고, 셋째로는 앞으로의 우리나라 기업의 공업통계활용활성화방안에 대하여 필자 나름대로의 의견을 진술하고자 한다.

In order to analyze the problems and improvement methods in the quality management of domestic apartment construction projects, this study derived the four barrier factors through relevant literature survey and interviews with construction practitioners. Among these four factors, which are 1) policies and regulations, 2) technologies, 3) human and organization, and 4) other miscellaneous aspects, the human and organization factor is the main focus of this survey and it was decomposed into perception, management system, education, and system on quality management according to the Taguchi's S/N theory to survey existing problems and suggest improvement methods for them. The survey on the quality perception showed that all the members need to cooperate actively, and CEO and chief construction managers should recognize the quality as the highest priority and act by themselves accordingly. The survey on the quality management showed that they need to reform their business process to reduce redundant tasks and miscommunications among participants. Quality education should be provided in a way that people at different management level can be educated differently with close relation to their practices. Quality systems should help corrective actions against quality problems at construction fields. Also with clear quality management implantation polices and objectives, the quality system should be established in order to support better communication among project stakeholders.

The Korean defence industry has grown rapidly since the 1970s. In 2015, it generated more than 168 billion won in economic revenue, and exports exceeded 3.6 billion won. With the development of the defense industry, the level of the quality management system for major contractors has improved substantially, but there are many areas of the quality management system that still need improvement for small subcontractors. Therefore, in this paper, we develop a methodology to improve the quality management system for small subcontractors. Based on 101 collected cases, this methodology results in generally improved effects and generally improved methods. By applying the Russian Theory of Inventive Problem Solving (TRIZ) concept of a contradiction matrix, three improvement matrices are derived. A developed improvement matrix is the main support tool of this methodology. This methodology consists of four tasks and eight subtasks, and it can be used as a support tool for creative problem solving by the quality assurance department and the quality assurance manager for small subcontractors.

In the application development process is an important task to improve the quality of the data is the principal means for achieving the functional requirements of the wireless sensor network applications because it is the data obtained in the real world. It should be possible to meet the requirements for the quality improvement to those detailed for improving the quality in a short period of time for developing a prototype of an application and low cost. However, development of the existing methods can not be satisfied simultaneously in order to use a consistent abstraction because antinomical relation between ability of description and ease of description. In this paper, we propose a meta-data designed to support the improvement of data quality through abstract modeling language is also used in combination to a multiple of the other.

The integration of Quality Circles and Six-Sigma has gained attentions for the attainment of enhanced customer satisfaction, costs reduction, and improved business performance. The purpose of this paper is to verify the benefit from the integration of Quality Circles and Six-Sigma by applying the integrated process for an alcohol manufacturing line. In the integrated process, we used the first three steps of Six-Sigma of Define, Measure, and Analyze(D-M-A) and then applied the concept of Quality Circle, which has good performance in the Improvement and Control(I-C) process. For the selection of the theme of quality circles, Analytic Hierarch Process(AHP) is used, and we also employed the experimental design, which is designed to find an optimal operating condition. Furthermore, the results of the economic analysis confirm that the integration process would be successful in reducing the incidence of defects and the quality cost.

This study sheds light on the quality aspect of cloud computing services as next IT platform. Three tasks of the research are to extract the quality factors of cloud service from the user's viewpoint, empirically analyze the perceptual differences between the user group and the provider group by applying the IPA technique, and suggest some quality factors that need to be improved. Based on the previous researches and focus group evaluation, 13 quality factors have been established. Two field surveys have been performed respectively to collect the perceptual importance and satisfaction level of the users and the providers. It is shown that the quality satisfaction of the user group is lower than the quality perceived by the providers. And there exist significant differences between two groups in respect to quality importance level and IPA matrix. In conclusion, 6 quality factors that need to be improved are suggested such as service functionality, service availability, interoperability, scalability, confidentiality, and provider's responsiveness.
