  • Validation specifies and coordinates all relevant activities to ensure compliance with good laboratory practices (GLP) according to suitable international standards. This includes validation activities of past, present and future for the best possible actions to ensure the integrity of non-clinical laboratory data. Recently, validation has become increasingly important, not only in good manufacturing practice (GMP) institutions but also in GLP facilities. In accordance with the guideline for GLP regulations, all equipments used to generate, measure, or assess data should undergo validation to ensure that this equipment is of appropriate design and capacity and that it will consistently function as intended. Therefore, the implantation of validation processes is considered to be an essential step in a global institution. This review describes the procedures and documentations required for validation of GLP. It introduces basic elements such as the validation master plan, risk assessment, gap analysis, design qualification, installation qualification, operational qualification, performance qualification, calibration, traceability, and revalidation.

  • The study conducted questionnaire analysis to 413 industrial safety field employees in order to examine the necessity and validity of industrial safety field's 17th neo-job classification based on National Competency standards(NCS). As a result, 50.1% of industrial safety management field and 43.3% of industrial health management field answered that classification details of occupational safety and health management field are classified by job(duty) performance. Industrial safety management field recognizes that management and engineering section play a significant role in their work, while industrial health management field recognizes worker's health care and work environment management and overall control of work environment assessment to be significant in their work. Furthermore, industrial safety management field recognizes that separating qualification and foundation of 'construction safety manager', 'chemicals(safety and health) manager', '(toxic)risk assessment evaluator or risk factor manager' to be highly significant. The study is meaningful in that it suggests industrial safety field's qualification items practical in industrial sites.

  • Photovoltaic and Thermal collector (PV/T) systems are renewable energy devices that can produce electricity and heat energy simultaneously using solar panels and heat exchangers. Since PV/T systems are exposed to the outdoors, their reliability is affected by various environmental factors. This paper presents a reliability test for a PV/T system and evaluates the test results. The reliability assessment entails performance, environment, safety, and life tests. The factor that had the greatest influence on the life of the system was the hydraulic pressure applied to the heat exchanger. A test was conducted by repeatedly applying pressure to the PV/T system, and a reliability analysis was conducted based on the test results. As a result, the shape parameter (β) value of 5.6658 and the B10life 308,577 cycles at the lower 95% confidence interval were obtained.

  • 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.

  • The purpose of this paper is to improve efficiency in the construction and operation of a total management system for the national technical qualification through the design and development of a real-time data sharing system which is connected with the management system of external consignment. The current a total management system for the national technical qualification precesses the work depend on information and results which pass over by external IT company. But this method of processing has some unstable elements with regards to information reprocessing, functional supplement, system stability, etc. The proposed system's technological concepts have been tested through a basic simulation pilot program. The pilot program will be expanded to include the local Chamber of Commerce and Industry because the stability of the system was proved through its application to the real-time national technical qualification examination of KCCI(Korea Chamber of Commerce and Industry). The real-time data sharing system has shown great efficiency in terms of system management, and has solved problems of developmental period for information reprocessing and functional supplement. The real-time data sharing system has been given good evaluations with regard to the convenience of their use and the management system for operators and supervisors.

Advanced Emergency care Instructor Qualification Course Development (1) based on advanced emergency care instructor job analysis and paramedic job description. (2) Learning of emergency care instructor qualification course is continuous. It is important to begin at the learner's level of knowledge and to relate new learning to information the learner needs. (3) Learning of emergency care instructor qualification course is purposeful and must make sense to the learner. Progress in learning must make sense to the learner. Progress in learning must be constantly appraised through feedback. The purpose of learning BLS information and skills must be kept in sharp focus. (4) Learning involves as many senses as possible. The more stimulating a learner activity is to the senses, the longer the information will be retained. Conservative figures indicate that 75% of what is heard is for-gotten after 2 days. It has been said that learners remember (5) Learning activities must be appropriate for the emergency situation through the PBL educational method. In BLS lecture skill learning, the greatest proportion of class time should be spent in manikin practice, using performance sheets as a learning tool or guide. (6) Learning must be stimulating. Instructors can motivate learners by helping them achieve higher levels of proficiency and encouraging other levels of course completion, such as instructor and instructor trainer. (7) Learning is affected by the physical and social environment. The physical environment should be conducive to both the kind of learning taking place and the activities used for learning. Advanced emergency care instructor qualification course organized educational psychology, educational methodology I,II,III, educational material making skill, lecture & conversational skill, BLS theory & pratice lecture skill, minic lecture designed PBL module. test of minic lecture & pratice lecture skill.

This paper researched skills and created the skill level through reviewing domestic & foreign documents, interview with experts and in-depth discussions with expert group focusing on terminologies commonly used in the industrial settings. As a result of skill classification, authors were able to classify skills into three categories in medium-scale classification and 11 categories in small-scale classification, and also into total 42 categories through the re-classification of the small-scale classification. The skill level in the area of machine were classified the skill level in the area of machine into 7 level by reflecting the level system of the korean qualification frameworks, qualification and education course, and skill level in the industrial setting. Based on the skill frameworks, we provided definition of skill and skill group, definition of each different skill, and performance standards by skill and level. also, This paper suggests improving measure of national technical qualification items through analysizing linkage situation between skill frameworks & qualification items.
