The purpose of this study is to establish effective quality control activities to maintain proper operation rates and improve the performance of research and development weapon systems. Quality control improvement measures suitable for the actual conditions of our military were identified by comparing the operational methods and advantages/disadvantages of the domestic quality control systems Defense Quality Management System and Defense Quality mark with those of the systems employed in the US(QPL and QML). In order to ensure the reliability of the weapon system, it is imperative to operate a design-oriented self-quality management system through manufacturing-oriented government-led inspection and to expand and reorganize the certification system divided into manufacturing items and companies.

The world dairy industry has been driving their dairy policy on the basis of the self-supportihg principle. With progressing the GATT negotiation, the objective production amount has been reduced to maintain the optimum level, which decreasing the extra supply and over-stock before the U.R talks. The Oceania countries, where has the price competition capability, are continually increasing the milk production amount. Even through the USA is trying to increase their production amount with new export policy, the U.S.S.R collapse-down caused to decrease the milk production in world-wide basis. Because the U.S.S.R produced the highest amount of milk in the world. Moreover Europe Union countries, which recorded the half amount of dairy products in the world was decreasing their milk production. Therefore, about 4% of shortage is encountering at major dairy production countries in the standpoint of supply and demand. The drastic increasement of foreign dairy product import affects the domestic dairy industry with raw milk replacement and new dairy food demands creation since 1995, the initial period of free import system. Now, the domestic dairy industry are facing the inevitable problems such as the correction of producting and processing system. First of all, our dairy industry should resettle down the dairy production structure on the basis of self-supply of raw milk and offer the accurate dairy food informations. We still need to improve the raw milk quality. Also, more efforts are needed to have proper raw milk price policy. General domestic policies including the settlement of raw milk supply and demand, the reliability of inspection system in raw milk, ideal raw milk price system, centralization of raw milk collection, specially separated dairy organization should be improved legally in our dairy industry.

Early generations of products had little to no inherent capability to test themselves. The technologies involved often required only visual inspection and limited probing to troubleshoot the system once it was turned over to maintenance personnel. However, as the complexity of military and commercial systems grew, symptoms of failure became less noticeable to the operator. Therefore, the procedure to access, inspect, repair and replace a component became complicated, the requirements for personnel skill and testing equipment increased. and it took too long of a time to maintain a system. Meanwhile, the need for availability became more mission-critical and maintenance become very expensive. The obvious solution was to design in-system circuits or devices to self-test the primary system, the Built-In-Test(BIT) was born. This approach has continued right on up through present systems and is an integral part of systems now being designed. The object of this paper is to present a state-of-the-art research for filtering out the BIT diagnosis mistakes using Bayesian analysis and develop the algorithm for Redundant systems with BIT to improve BIT diagnosis.

We investigated the foodservice management practices in various operation types of childcare centers in Asan, Chungnam Province, with the intention of improving the quality of foodservice and providing the basic information for establishing more effective and efficient foodservice model system. Self-completed questionnaires were collected from the directors of 174 child care centers. The statistical analysis was completed using SPSS Ver. 12.0 program. The followings are about the results of this study. Approximately 94.8% of the directors were women with the average age of 40.3. All of the investigated facilities executed foodservice; the facilities of 96.2% had been self-operated, 1.9% was contract-managed and the remaining 1.9% served delivered meal from outside. Only 20.0% of the investigated centers employed a dietitian. In most of the centers, meals were prepared in a conventional manner and approximately 85.3% of the centers are serving only snacks twice a day as a supplementary due to financial difficulties. Menu planner of the facilities, which have no dietitian was the director (35.8%) or the cook (25.7%). In most centers, the directors purchased the food materials (67.5%). Material inspection was done by the director (54.9%) or the cook (40.5%). However, home care centers did not inspect the food material. These results indicate that food service management guidelines need to be established by the facility type with the government control and financial support. Especially, dietitian employment and the efficient foodservice model system establishment are questions that confront us.

Purpose - The purpose of this study is to expand the taxpayer's rights protections, which are covered in the previous studies, and to suggest ways to increase tax inspection efficiency as a way to induce fidelity reporting under the final tax return system and to lower tax compliance costs. Design/methodology/approach - The tax audit is a necessary system for the taxpayer to induce self-reporting in a sincere manner, but it is necessary to harmonize the realization of fair taxation and the rights of taxpayers because it is likely to infringe taxpayer rights in the process. Research implications or Originality - The purpose of this study is as follows. First, the government will seek ways to improve tax investigations to strengthen the protection of taxpayers' rights by increasing the fairness and procedural transparency of the current tax investigation system, as pointed out in the National Tax Administration Reform T / F. Second, we will consider ways to enhance the effectiveness of tax audit as a means of inducing faithful tax in Korea's tax system, which assumes sincere taxpayers.

신장은 간장과 가장 유기적인 관계가 깊은 장기로 혈액 중에서 체내 신진대사 결과 생긴 노폐물을 걸러내 오줌을 만들어 체외로 배출하는 기능을 한다. 그러나 신장은 문제가 발생할 경우 인체가 느끼는 자각증상이 크지 않기 때문에 장기 파손이 상당 부분 진행되어야 그 증상을 알게 된다. 따라서 사회적으로 신장 질환 진단에 대한 중요성이 증대되고 있다. 이를 위해 본 논문에서는 한방의 4대 진단법 중에서 망진과 청진 분야를 이용하여 신장질환에 대한 진단 방법을 제안하고자 한다. 본 논문에서 개발할 시스템은 크게 두 가지로 나누어진다. 하나는 입력 영상에 대한 보정을 통해 정확한 색상 값을 추출하고 최적화된 결과 영상을 통해 신장과 관련된 얼굴에서의 지각 부분의 색을 분석하고 그 값을 이용하여 신장 질환 진단을 하고자 한다. 또 하나는 신장과 음성 신호와의 관계론 비교, 분석하여 이를 입증하는 시스템을 설계하고자 한다. 끝으로 실험을 통해 제안한 방법의 유용성을 입증하고자 한다.

Objectives: This study is based on Public Care Service for Chronic Diseases in Incheon Metropolitan City featuring Health-Point Service. It is objective to evaluate whether the service could improve self-management ability of hypertension and diabetes patients. Methods: The knowledge about diabetes and hypertension, which can be improved by educational intervention, is considered as one of the most important factor for self-management ability. While the education service have been conducted, 194 patients who have been diagnosed as hypertension and diabetes within 3 months were included. They completed questionnaires two times within 4 months period, which give information about the knowledge, service registration and education experiences. For further inspection, 396 patients who had been diagnosed formerly were studied by cross-sectional analysis. Results: Regardless of service registration or educational intervention, there wasn't statistically meaningful difference between the initial and the follow-up assessments on the knowledge. However, when investigating formerly diagnosed patients, educated patients had better knowledge on hypertension compared with non-educated patients and registered patients, educated patients had the better knowledge on diabetes compared with non-registered patients, non-educated patients. Additionally, analyzing each questions, educated patients got higher grades in questions about definition of hypertension, diabetes managements which they can practice in daily lives. Conclusions: It is probable that long-term service registration and education experiences could improve the knowledge and self-management ability.
