A design of reliability qualification test based on performance distribution is developed. In general, the performance of an item degrades as the time goes by and the failure of an item occurs when the performance degradation reaches the pre-determined critical level. This article considers the reliability qualification test based on a more tightened critical value at the earlier stage to reduce the evaluation testing time and cost. A numerical example is provided to illustrate how to use the developed reliability qualification test.

In general, the performance of a component degrades as time goes by and failure of a component occurs when the performance degradation reaches a pre-specified level. It is difficult to obtain the failure time distribution data or the necessary number of failure data especially for the metal or machine part. Thus, a design of reliability qualification test based on performance distribution is more effective than failure time distribution. In this study, a performance-based reliability qualification test is developed and a numerical example is provided to illustrate the use of the developed reliability qualification test. This approach could be applied to many kinds of metal or machine part whose magnitude of strength could not be evaluated during at any random points but judgement can be made by only failure of the part. Besides, it is also possible that any parts which have a similar failure characteristics could be applicable to the developed reliability qualification test.

Most aircraft accidents are attributed to crew error, but traditional training programs focus on individual training and evaluation. So, FAA developed innovative training and qualification programs that incorporate the most recent advances in training methods and techniques. AQP(Advanced Qualification Program) is focus on crew and individual performance in both training and evaluation. The primary goal of AQP is to achieve the highest possible standard of individual and crew performance. Nowaday, a lot of Airlines of US and Europe are managing aircrew qualification with AQP or ATQP. This paper proposed government's organization, documents, personnel and education to apply AQP to Korea, as well as domestic airlines available application of AQP.

The goal of this paper is to estimate firm performance of hospital coordinators through a survey on employees of medical institutions placed in Busan and Ulsan. The survey for this paper is constituted by 34 questions of 4 groups related to firm performance, qualification requirement, general fact and a certificate of qualification. The survey was carried out from September 12th, 2008 to September 24th 2008 and 388 question sheets collected finally and used for result analysis. In the result analyses related to hospital coordinator and firm performance, we found some principal outcomes such that 88.6% of respondents approved that hospital image by patients and customers is raised, 87.7% of respondents approved that degree of patient's satisfaction on hospital services is raised, and 81.5% of respondents approved that employees recognized importance of services on customers, by hospital coordinators. In the result analysis on differences in firm performance by presence of a certificate of qualification for hospital coordinator, there were meaningful differences in degree of patient's satisfaction, financial performance and degree of employee's recognition on importance of services. From the all of the above results, we verified that establishment and improvement of educational process for hospital coordinator should be performed through researches on degree of patient's and costumer's satisfaction for hospital coordinator, degree of hospital coordinator's satisfaction for the job and surveys of requirements from related industry.

민간경비가 도입된 지 60여년이 지난 현재 민간경비와 관련된 국가공인 자격으로는 경비지도사와 신변보호사 자격제도가 있다. 본 연구에서는 2013년도부터 국가공인자격으로 실시 되어오고 있는 신변보호사 자격검정 사항 중에서 2차 실기시험제도의 문제점에 대하여 논의하였다. 현행 신변보호사 자격검정은 1차 학과시험과 2차 실기시험으로 분류하여 실시하고 있는 가운데 신변보호사의 자격 검증을 엄격히 하여 응시자에 대한 만족도와 대중의 신뢰도를 높여가야할 시기에 봉착하였다고 판단되어 신변보호사 실기시험제도의 문제점에 대한 개선방안을 다음과 같이 제시하였다. 첫째, 현재 단순하고 비교적 기초적인 실기시험 평가 항목의 난이도를 다양화 하여 구분하는 것이 필요하다. 둘째, 현재 실기시험 평가기술은 합기도의 기술분야에 치우쳐 있다고 볼 수 있어 각 무도분야의 실질적 활용가능성이 높은 기술을 복합적으로 접목시켜 다양화 하는 것이 필요하다. 셋째, 현재 일반화 되지 않은 실기시험 평가위원제도를 전문화된 실기시험 평가위원으로 선정할 수 있도록 기준안 마련이 필요하다. 넷째, 현재 실기시험 평가위원과 응시자의 관계에 있어 지인인 경우가 많아 객관성확보차원에서 제척제도를 신설하는 것이 필요하다. 이와 같이 신변보호사 자격검정 실기시험제도의 전문성을 고양시켜나가기 위해 관련기관의 제도적 개선이 시급히 이루어져야 할 것이다.

Main coolant pump (MCP) is a canned-motor-type axial pump to circulate the primary coolant between nuclear fuel rods and steam generators in an integral type reactor. The reactor is designed to operate under condition of 310 oC and 14.7 MPa. Thus MCP has to be tested under same operating condition as reactor design condition in order to verify its performance and safety. In present work, a test loop to simulate real operating situation of the reactor has been designed and constructed to test MCP. And then, as a part of qualification test, canned motor functional test and pump hydraulic performance test have been carried out upon a prototype MCP. Canned motor efficiency and pump hydraulic characteristics including homologous curves and NPSH curves were obtained from the qualification test.

Environmental Qualification has been almost developed except those of Non-Material Sub-components for valves and pumps though the time has only passed about 10years since EQ test launch of Korea. However EQ test has been performed by a few of engineers under the conditions that experience of EQ test is insufficient and EQ system is not developed completely. In recent years, Strengthen Nuclear Safety Regulation is being done Strictly Nuclear safety components Verification Procedure for Non-Material Sub-components, but the reports contain only performance test results, not Enviro nmental test methods relating to real Aging Degradation. In this Study, there were developed to performance systematically research to acquire EQ technology for five specimens of the Non-Material Sub-components in the Nuclear Power Plant.

Since the late 1990's, FAA, NASA and the aerospace industry have worked together to develop the sharing system of the composite material qualification databases which were obtained through the standardized fabrication and testing procedures. The result was what is now known as the AGATE(Advanced General Aviation Transport Experiments) or NCAMP(National Center for Advanced Materials Performance) methodology, a more cost-effective concept that shifts the major responsibility for qualification and testing from the aircraft manufacturer to the material supplier. The properties of composite materials are largely dependent on the testing as well as the raw material properties and the manufacturing process including the process control parameters. Thus it is important in the composite material qualification to comply with the standardized testing procedures. In this paper, I will describe the standardized witness methodologies of certification engineers to reduce the effect of testing variability within the qualification data.
