  • The Comprehensive quality assurance for radiation oncology provides an overall organizational structures, responsibilities, procedures, processes and resources for assuring the quality of patient management by radiation treatment. Superior performance of modern radiotherapy equipment will be essential part of quality assurance in radiation oncology, which high degree of accuracy and consistency should be maintained under the optimal quality assurance program. Besides quality control of all radiation equipment, this review also emphasizes quality assurance of clinical aspect such as adequacy of the medical decision-making which eventually leads to the treatment prescription, accuracy of treatment procedure from treatment preparation to radiation delivery, and the significance of assessment of treatment outcomes with structure and process.

  • Purpose: This study is in order to secure high quality of military supplies, it is important to secure design quality in the development phase. I will review how to establish a quality assurance system in the development phase based on the author's seminar presentation contents and application example of Hanwha Systems Co., Ltd. Methods: To guarantee design quality in the development phase, in 2002, quality assurance system that is adequate for SQA(Software Quality Assurance)'s requirements of CMM(Capability Maturity Model) was conduct. In 2009, based on the CMMI(Capability Maturity Model Integration) Level 5, there has been continuous and reenforced quality assurance activities. Results: By suggesting the construction and a case study on application of R&D quality assurance, it would be helpful for companies aiming to construct or enhance quality assurance system. Conclusion: To secure high quality for military supplies, a development QA system should be established to secure quality in the development phase. In addition, Total life cycle QA system for development, mass production and operation phase should be reestablished.

  • This paper introduces Primetals Technologies' Through-Process Optimization (TPO) Services and Through-Process Quality Control (TPQC) System, which integrate domain knowledge, software, and automation expertise to assist steel producers in achieving operational excellence. TPQC collects high-resolution process and product data from the entire production route, providing visualizations and facilitating quality assurance. It also enables the application of artificial intelligence techniques to optimize processes, accelerate steel grade development, and enhance product quality. The main objective of TPO is to grow and digitize operational know-how, increase profitability, and better meet customer needs. The paper describes the contribution of these systems to achieving operational excellence, with a focus on quality assurance. Transparent and traceable production data is used for manual and automatic quality evaluation, resulting in product quality status and guiding the product disposition process. Deviation management is supported by rule-based and AI-based assistants, along with monitoring, alarming, and reporting functions ensuring early recognition of deviations. Embedded root cause proposals and their corrective and compensatory actions facilitate decision support to maintain product quality. Quality indicators and predictive quality models further enhance the efficiency of the quality assurance process. Utilizing the quality assurance software package, TPQC acts as a "one-truth" platform for product quality key players.

  • There are several models for process quality assurance by quality system (ISO 9000), process capability analysis, acceptance control chart and so on. When a high level process capability has been achieved, it takes a long time to monitor the process shift, so it is sometimes necessary to develop a quicker monitoring system. To achieve a quicker quality assurance model for high-reliability process, this paper presents a model for process quality assurance when the fraction nonconforming is very small. We design an acceptance control chart based on variable quality characteristic and time-censored accelerated testing. The distribution of the characteristics is assumed to be normal or lognormal with a location parameter of the distribution that is a linear function of a stress. The design parameters are sample size, control limits and sample proportions allocated to low stress. These paramaters are obtained under minimization of the relative variance of the MLE of location parameter subject to APL and RPL constraints.

  • Quality Assurance is a system of activities whose purpose is to provide assurance that the over all quality control job is in fact being done effectively. In this paper, we tried to develop the fundamental quality assurance procedures that can be applicable to the new-product design stage, to the production stage and to the after-sales stage of the production system.

  • A prerequisite for improving the quality of a product is to enhance the quality of its parts supplied from outsourced enterprises. An enterprise certified by ISO 9001 Quality Management System is expected to develop their effective quality assurance system and maintain it through continuous control and improvement, thereby ensuring the good quality of products that they produce. However, it is reported that small and medium-sized enterprises certified by ISO 9001 have difficulty establishing an effective quality assurance system. This study aims to propose a new method of improving a quality assurance system that can be more effective in small and medium-sized enterprises. This study collectively considered requirements specified in several international standards on quality system and the results of expert group brainstorming to identify evaluation areas and items for assessing a quality assurance system. Based on these evaluation areas and items, a set of checklists for diagnosing and improving a quality assurance system was developed. In order to demonstrate the usefulness of the proposed method, this study applied it to ten small and medium-sized enterprises and could identify four approaches for improving their current quality assurance system. The presented improvement method, which consists of establishment of quality goals and quality innovation plan, defective products corrective activities, 4M and design change process, improvement of customer quality information management, is expected to be utilized as a useful tool for the enhancement of the quality assurance system of small and medium-sized enterprises.

  • 본 연구에서는 해외 원격개방대학 질 관리 사례 가운데 선도적인 것으로 알려진 영국 개방대학교와 인도네시아 터부카 대학교의 사례를 검토하여 우리나라 원격대학 질 관리 체제 구축에의 시사점을 찾아보았다. 영국 개방대학교와 터부카 대학교는 모두 재학생이 10만명 이상인 메가 유니버시티로서 효율적인 질 관리를 위해 중앙집권적인 질 관리 체제를 구축하고 질 관리를 담당하는 전담부서를 설치하고 있다. 또한 대학 구성원들이 질 관리 중요성에 대한 인식을 공유하고 직원들의 업무에 대한 평가 및 모니터링을 강화하여 지속적인 개선을 추구하는 질 관리 문화가 정착되어 있다. 교육의 질 관리는 그 성과가 가시적으로 확인되는 것도, 특정한 대가가 주어지는 것도 아니기 때문에 장시간에 걸쳐서 신중하게 계획 검토되면서 통합적으로 진행될 필요가 있다.
