In Republic of Korea, there are many Quality Assurance protocol for general radiation treatment machine such as linac. However, Quality Assurance protocol for radiosurgery treatment system is not ready perfectly. One of the radiation treatment machine for radiosurgery, novalis system needs to suitable Quality Assurance protocol for using it right way during radiation treatment and maintaining suitable accuracy for daily, weekly, monthly and annually periods. Therefore, in this article, we develop Quality Assurance protocol for novalis system. We collected and analysed domestic and foreign novalis Quality Assurance protocol. After that, we selected essential QA items and each tolerance range for developing proper QA protocol, and we made anatomical phantom for execution of selected QA items and evaluation of overall state of QA, and then, we use this measured value as a reference. Quality Assurance items are consisted of Mechanical accuracy QA part and Radiation delivery QA part. Mechanical accuracy QA part is comprised of radiation generation machine part, assistive devices part and multi-leaf collimator part. Radiation delivery QA part is divided into radiation isocenter accuracy and dosimetric evaluation. After that, developed novalis QA tables are made by using these QA items. These novalis QA tables would be used to good standard in order to maintain apt accuracy for radiosurgery in daily, weekly, monthly and annually periods.

2002년 7월부터 시행될 한국의 제조물책임법은 제조물의 결함으로 인한 소비자의 피해구제가 목적으로 이에 따라 기업으로서는 제품의 품질과 안전에 대한 부담은 더욱 증가하게 되었다. ISO9001:2000 품질경영시스템의 요구사항은 고객만족 지향에 대한 프로세스의 지속적인 개선을 강조하여 개정되었고, 고객의 요구는 제품의 안전을 더욱 중요시하는 추세로서 이러한 대응방안을 ISO9001:2000 품질경영시스템의 요구사항에서 고찰·제시하고자 한다. ISO9001:2000 품질경영시스템은 경영에 대한 프로세스 접근방식의 도입으로 프로세스의 입력사항으로 고객이 중요한 역할을 하며, 고객의 요구사항이 충족되었는지를 검토하며, 지속적인 고객만족을 위해 프로세스를 관리한다. 본 연구에서는 먼저 제조물책임법의 도입배경과 Is09001:2000 품질경영시스템의 특징을 고찰한다. 그리고, ISO9001:2000 품질경영시스템과 PL과의 관련성을 제고하여 제조물의 결함 유형별, 경영관리지침 항목, 소송상의 항목으로 분류하여 제조물책임 대응방안으로 ISO 9001:2000 품질경영시스템을 제시하고자 한다.

This study identified the important categories and items about evaluation criteria of e-learning quality assurance by comparing evaluation criteria between Korea and France case. For deriving the conclusion, this research analyzed the Korea quality assurance case which is consist of success or failure for evaluation of quality assurance, and built the generic quality model of e-learning evaluation criteria. A generic model about evaluation criteria, categories, and item of e-learning quality assurance, which should be reflected on French quality criteria, were developed based on statistical approach. This research suggests a evaluation criteria which can be applied to African and Asian countries, that are related to AUF, as well as Korea. The result of this study can be applied to all organizations around the world which prepare for e-learning quality assurance, and at the same time it will be a valuable resource for companies or institutions which want to be evaluated e-learning quality assurance.

Various quality models using quality factor, quality criteria and metrics have been proposed in order to evaluate quality of software products. However, a customized quality model which is specific to the characteristics of software component is required. In this paper, we propose external quality prediction techniques enable us to predict what external quality the final software product will have by using metrics as with internal attributes of software in development. We also propose a model not only for measuring quality by using metrics but also for applying internal attributes of ISO 9126 into artifacts of software component development.

This paper suggests the border based HSFI algorithm to hide sensitive frequent itemsets. Node formation of FP-Tree which is different from the previous one uses the border to minimize the impacts of nonsensitive frequent itemsets in hiding process, including the organization of sensitive and border information, and all transaction as well. As a result of applying HSFI algorithms, it is possible to be the example transaction database, by significantly reducing the lost items, it turns out that HSFI algorithm is more effective than the existing algorithm for maintaining the quality of more improved database.

The purpose of this study is to identify priority factors for improving service quality of cosmetic stores in drug stores(DRS) and department stores(DES) and to provide basic data for improving service quality of cosmetic stores by analyzing the service quality based on the Kano model and the Potential Customer Satisfaction Improvement (PCSI) Index. As a result, most items of quality factors of cosmetic stores in both stores were evaluated as attractive quality factors. As a result of PCSI Index comparison, the quality factors of 'Reliability', 'Responsiveness', and 'Empathy' items for DRS and 'Empathy' and 'Reliability' items for DES had higher priority for improvement. That is, if these factors are improved, there is a high potential to improve customer satisfaction. Through this study, practical implications were provided by identifying service quality factor classification and priorities for customer satisfaction improvement of DRS and DES. This is expected to contribute to the guidelines for improving customer satisfaction in the future.

This paper aims to develop an evaluation model for library mobile services in terms of service quality. First, a literature review of the service quality evaluation model and the mobile library service evaluation was conducted. Then, based on the analysis, the evaluation model consisting of 4 quality dimensions, 10 quality factors, 39 quality measurement items was developed. Delphi method was applied to verify the validity of the model. Finally, a final model consisting of 4 quality dimensions, 9 quality factors, and 37 quality measurement items was derived. The evaluation model proposed in this study can be used as a measure of library mobile service quality and can be used as a guideline for improvement of library mobile service.

The types of test items which were recorded in this test report of quality control domestic $^{18}F$-FDG radiopharmaceutical which consisted of 13 different types: appearance, half-life, radioactive heterokaryosis, radiochemical Confirmation (measure of Rf value), radiochemical Purity, Ethanol, Acetonitrile, Kryptofix, Aluminium, pH, Endotoxin, aseptic test, and radioactivity${\cdot}$ml-1. The record was fully recorded in 'appearance', 'radioactive heterokaryosis', 'pH', 'Endotoxin', and 'aseptic test'. In 'half-life', 'radiochemical Confirmation (measure of Rf value), 'radiochemical Purity', 'Ethanol', 'Acetonitrile', 'Kryptofix', 'Aluminium', 'radioactivity${\cdot}$ml-1', there were differences in records of each manufacturing business on radioactive medicine and medical supplies. The result of the test showed all 13 items of quality control test were 100% suitable on the basis of recorded data. There were more radiopharmaceutical made in the laboratory than in hospitals and businesses and in for result of suitability test, the laboratory showed higher suitability than did the hospitals or businesses. Domestically, there are differences of the test report items in the safety of radiopharmaceutical of each facility, and since it is not standardized, supplements are needed. To submit standardized test reports of quality guarantee in radiopharmaceutical, GMP of U.S. and CE Mark of Europe should be referred as well as receiving advice from professionals to standardize as suitable domestic standard.

소프트웨어의 개발 과정에서 생명주기 단계별로 시험 측정 항목을 개발하여 적용함으로써 각 단계별로 고품질의 개발 산출물을 생산할 수 있으며 결과적으로 고품질의 소프트웨어 개발에 기여하게 된다. 이러한 과정을 거쳐왔다면 소프트웨어의 오류는 최소화되었겠지만 시험 단계를 통해 잔존하는 오류를 발견하여 개선할 필요가 있다. 본 연구에서는 생명주기 단계 중 소프트웨어 시험 단계의 테스트를 위한 시험 측정 항목을 개발하여 시험 단계에서 최종적으로 소프트웨어의 품질을 향상시킬 수 있는 여건을 마련하였다.
