Quality cost system is a key element of an organization's quality program. In this paper we suggest a quality cost evaluation system for aerospace industries considering the aircraft development and manufacturing processes. To reduce the cost of poor quality, we present an extended quality cost concept and detailed quality cost categories. The extended quality cost includes prevention cost, appraisal cost, failure cost, and the cost hidden in the processes. The evaluation of this extended quality cost will be helpful in identifying critical quality issues in aerospace industries.

The goal of this research was to develop a portable system that could be used to evaluate the quality of milk in real time at a raw milk production site. A real-time portable quality evaluation system for raw milk was developed to enable non-destructive quality evaluation of somatic cell count (SCC), fat, protein, lactose, and total solid (TS) in milk samples. A prediction model of SCC, fat, protein, lactose, and TS was constructed using partial least squares (PLS) and 200 milk samples were used to evaluate the prediction performance of the portable quality evaluation system and high performance spectroscopy. Through prediction model development and verification, it was found that the accuracy of high performance spectroscopy was 90% for SSC, 96% for fat, 96% for protein, 91% for lactose, and 97% for TS. In comparison, the accuracy of the portable quality evaluation system was relatively low, at 90% for SSC, 95% for fat, 92% for protein, 89% for lactose, 92% for TS. However, the measurement time for high performance spectroscopy was 10 minutes for 1 sample, while for the portable quality evaluation system it was 6 minutes. This means that the high performance spectroscopy system can measure 48 samples per day (8 hours), while the portable quality evaluation system can measure 80 (8 hours). Therefore, it was found that the portable quality evaluation system enables quick on-site quality evaluation of milk samples.

It seems to be less important to quality record than document control. But quality records provide a objectve evidence for certain product. So, the requirements of quality record is more serve than that of design document. It is obvious that quality record control promotes accumulation of know-how. The puepose of this study is to possible implementation methods through analysis of Code requirements. This paper suggests the considerations when establishing the quality records control system.

Quality audit is one of tools to evaluate the effectiveness and compliance of quality system. Quality system will be improved through quality audit. This paper describes the considerations such as audit team, audit process, audit checklist and auditor's communication skills to perform effective quality audit. The result of quality audit depends on the auditees attitudes. Thus, the auditor's manner is very important to gain a good audit result.

본 연구의 목적은 ERP시스템의 품질요인이 조직성과에 어떠한 영향을 미치는가를 실증적으로 조사 및 분석하였다. 많은 선행연구들이 일반품질요인에 초점을 두는 대신에 본 연구는 설문지를 사용하여 ERP시스템을 채택한 기업에 있어서 품질요인과 조직성과간의 상호관련성을 조사 연구하였다. 특히 선행연구들은 시스템품질과 정보품질만을 연구대상으로 설정한 것이 주류를 이루고 있는데 본 연구에서는 서비스품질을 추가하여 조직성과와의 관련성을 연구하였다는데 의미가 있다. 설문지는 ERP시스템을 도입한 기업을 대상으로 품질요인과 조직성과간의 관련성의 설문으로 구성된다. 연구결과는 다음과 같다. 첫째, ERP시스템의 품질요인이 조직성과에 t검정으로 영향을 미친다는 것이다. 둘째, ERP시스템의 품질요인이 t검정으로 조직성과에 통계적으로 유의하게 영향을 미친다는 것이다. 이 결과는 실무계 및 교육계에 유용한 통찰력과 정보를 제공할 것으로 기대한다. 첫째, ERP시스템을 기업이 도입할 때, 품질요인이 조직성과에 유의적인 영향을 미친다는 것을 사전에 숙지하고 품질요인에 대한 투자와 연구가 행되어야 한다는 것이다. 둘째, 본 연구는 지금까지의 선행연구와는 달리 서비스품질을 추가하여 연구함으로써 품질요인을 세부적으로 접근하였다는데 그 실용가치가 높다고 판단되며, 셋째, 본 연구는 ERP시스템의 품질요인의 질적향상에 대한 학문적 기초를 제공한다.

Purpose: Nowadays, the risk assessment system is widely used in many industrial and public areas to reduce the possible risks. The system is used to determine the priorities of the government quality assurance works in Defense Agency for Technology and Quality. However, as the risk assessment system is used for other purposes, there are some items that need improvement, and in this study, we propose improvement plans by benchmarking the risk assessment systems of other institutions. Methods: In this paper, first, the procedures of risk assessment system used in many industrial sites were reviewed, and how each institution specialized and applied the system. Afterwards, by benchmarking various risk assessment systems, an improvement plan on how to operate the risk assessment system in the case of government quality assurance for centrally procured military supplies was presented, and practical application cases were presented to prove the usefulness of the improvement plan. Results: The proposed risk assessment system differs from the existing system in five major aspects. First, inputs, outputs, and key performance indicators were specified from the systematic point of view. Second, risk analysis was analyzed in four dimensions: probability of occurrence, impact, detection difficulty. Third, risk mitigation measures were classified, control, transfer, and sharing. Fourth, the risk mitigation measures were realized through document verification, product verification, process verification, and quality system evaluation. Finally, risk mitigation measures were implemented and the effectiveness of the risk mitigation measures was evaluated through effectiveness evaluation. Conclusions: In order for the risk assessment procedure proposed in this study to be applied to actual work, it is necessary to obtain the consent of the person involved in the work due to the increased time for risk identification and preparation of the government quality assurance log, and a change in the information system that performs the actual work is required. Therefore, the authors of this study plan to actively perform internal seminar presentations and work improvement suggestions to apply these research outputs to actual work.

This paper presents a vision based autonomous inspection system for welding quality control of a RV sinking seat. In order to overcome the precision error that arises from a visible inspection by an operator in the manufacturing process of a RV sinking seat, the machine vision based welding quality control system is proposed. It consists of the CMOS camera and the NI vision system. The geometry of the welding bead, which is the welding quality criteria, is measured by using the captured image with a median filter applied on it. The image processing software for the system was developed using the NI LabVIEW software. The proposed welding quality inspection system for RV sinking seat was verified using experimentation.

Organizations worldwide have implemented quality management system, ISO 9001:2000 and environmental management system, ISO 14001:2004. Researches have been conducted regarding occupational health and safety management system, integration of these management systems, and extension to corporate social responsibility and sustain ability management system, ISO 26000. This paper examines quality and environment management systems for machinery and metal companies using audit results. We perform statistical tests to see if there are any significant differences of minor nonconformities for requirements of ISO 9001:2000 and ISO 14001:2004 based on implementation motive, operating periods, and organization's size. We also present causes and reasons for statistical differences and minor nonconformities to use as references for implementing efficiently quality management system and environment management system.
