As the expension of metropolis and increasing of housing site, GIL(Gas Insulated Line) comes to the fore as an alternative to overhead transmission line avoided by local resident. The certification and experimental test for the GIL is now in progress in under ground test lab, Go-chang. For the test, we propose a method of PQ(pre-qualification) test which is essential for development and field application in this paper. The test following this method take about 200 days or 300 days under the circumstances.

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.

본 논문은 정지궤도위성 관측탑재체 고속 데이터 전송을 위한 X-대역 이중모드 고전력 채널필터의 우주인증모델에 대한 멀티팩터 시험을 통하여 설계시 요구되는 8 dB 마진과의 비교 검토를 수행하였다. 해석적인 요구되는 마진을 시험을 통해서도 충족하며, 만족한 시험결과를 얻었음을 확인하였다. 멀티팩터의 설계 및 시험은 ECSS의 규격을 준용하여 시험이 실시되었으며, 이를 근간으로 설계시 마진을 충분히 확보되면, 별도의 시험 없이 우주인증 모델용 필터 개발에 있어서 참조하여 사용할 수 있을 것으로 제안한다.

This study aims to survey the perceptions held by students and field workers regarding the clothing-related qualification certificates, which can serve as the base for becoming clothing professionals, to compare and analyze the actual state of qualification certificates on the basic research level, and thus to search for the directions suitable for the clothing-related qualification certificates. The questionnaire method was selected for the study. The responses of 406 copies from students and 81 copies from field workers were used, and frequency analysis and t-test were done with the assistance of spss 10.0 statistics program, The findings are as follows. First, as to the qualification certificates perceived by the students, the certificates of colorist engineer and colorist industrial engineer were known most. 237 students, or 58.4% of the student respondents, had obtained the information about the qualification certificates mainly through the internet and mass media, and 77.3% of the students had a plan to get the qualification certificates. Second, as to the qualification certificates perceived by the field workers, the respondents indicated that school grades(43.2%) would be given the highest additional points at the time of employment, while the clothing-related qualification certificates gathered low responses of 11.1%. The field workers perceived that the qualification certificate of Western suit engineer(pattern) was needed for the job, while 45.4% of them perceived that no qualification certificate was required for the job. Third, both the students and the field workers showed low acquisition levels of the qualification certificates, and in view of their perceptions that the qualification certificates of languages or computer skills were more useful, the improvement is needed in order for the national certificates for the clothing-related skill qualification to develop in the more job-related directions.

The seismic qualification for the class 1E battery of Korea Multipurpose Research Reactor was accomplished by the analysis as well as testing. The full rack consists of 4 similar sections of typical frame structure and contains 60 cells. However, since the seismic qualification was required on the frame structure and only on 3 aged ones among 60 dells, 2 sections of the full rack were assembled as a test rack with 28 cells including the 3 aged cells for an economic test. Seismic analysis for the full rack was carried out using the finite element program ANSYS. The modal parameters identified from the resonance search thest on the test rack were used to the seismic analysis of the full rack. It was confirmed that the test rack could represent the full rack with regards to seismic responses and function of cells, and that the full rack and aged cells were qualified to the given seismic test requirements.

SMART Pilot is a multipurpose small capacity integral type reactor. Main coolant pump (MCP) of SMART Pilot is a canned-motor-type axial pump to circulate the primary coolant between nuclear fuel and steam generator in the primary system. The reactor is designed to operate under condition of $310^{\circ}C$ and 14.7MPa. Thus MCP has to be tested under same operating condition as reactor design condition to verify its performance and safety. In present wort a test apparatus to simulate real operating situations of the reactor has been designed and constructed to test MCP. And then functional tests, performance tests, and endurance tests have been carried out upon a prototype MCP. Canned motor characteristics, homologous head/torque curves, coast-down curves, NPSH curves and lift-time performance variations were obtained from the qualification test as well as hydraulic performance characteristics of MCP.

The study is conducted in order to establish validity of industrial safety field's neo-qualification composition by suggesting reengineering procedure of NCS based industrial safety field's qualifying occupational plan. Industrial safety fields are first classified into great classification which are environment energy safety, and then into sub-classification which are industrial safety management, industrial health management, and nondestructive test. NCS based neo-qualification plan is deveopled into progress as following steps; First, planning NCS neo-qualification system. Second, presenting work education combined program certification standard. Third, developing NCS based neo-qualification assessment standard. Fourth, developing work education qualification prototype problem. The process of qualification plan was composed with Worksheet 14 and with 4phase being completing summary of each section, certification and development of assessment standard, and development of prototype problem. As a result, Industrial safety manager was redesigned into Industrial sfety manager and Construction Safety Manager, and Occupational Health Care Manager was redesigned into Occupational Health Care Manager and Industrial Health Manager. This study, in conclusion, suggests development of qualifying occupation that could be applied to the integrated management system and development of future industrial safety field's specialized neo-qualifying occupation.

The materials applied to the aircraft fuselage, parts, and components must be verified by relative authorities in accordance with the procedures set by the airworthiness authority to achieve the aircraft type certification. There are no examples of domestic composite materials which were verified in order to be applied to aircraft structure. In this study, the composite material certification system of NCAMP, an American composite material standard certification organization, was reviewed and used as the fundamentals of the first aerospace composite material certification system in ROK(Fig 2,8). Also updated material certification documents were developed and confirmed by material certification engineers and inspectors. This aerospace composite material qualification system is intended to modernize the material certification system for AAM(Advanced Air Mobility) as well as aircraft and to enhance the understanding of related technicians and inspectors.

This paper presents the effect of fusion procedure on the fusion performance of the thermal butt fusion in the safety class III buried HDPE piping per various tests performed, including high speed tensile impact, free bend, blunt notched tensile, notched creep, and PENT tests. The suitability of fusion joints and qualification procedures was evaluated by comparing test results from the base material and buttfusion joints. From the notched tensile test result, it was found that the fused joints have much lower toughness than the base material. It was also identified that the notched tensile test is more desirable than the high speed tensile impact and free bend tests presented in the ASME Code Case N-755-3 as a fusion qualification test method. In addition, with regard to the single low-pressure fusion joint performances, the procedure given by the ISO 21307 was determined to be better that the one specified in the Code Case N-755-3.
