A diagnosis procedure that allows operators to successfully identify the nature of an on-going event is inevitable for an effective and appropriate recovery. Unfortunately, studies for a framework that can suggest a unified and consistent process in constructing a serviceable diagnosis procedure seem to be scant. Thus, a systematic framework that can be used to construct a useful diagnosis procedure is suggested. In this study, using a full-scope simulator of the reference NPP, an experiment is conducted to confirm the appropriateness of the suggested framework. As a result, it is shown that an operator’s diagnosis performance is improved when the revised diagnosis procedure is used. Therefore, it is reasonable to conclude that the suggested framework is useful in constructing an effective diagnosis procedure.
[기술논문] 데이터센터 에너지절감을 위한 베이스라인 설정 및 측정/검증(M&V) 평가기준 조사연구

IT industries are one of the major consumers of energy, with data centers consume an especially large portion of that power. The typical IT in a data center consumes up to 30 times more energy than a typical office building. M&V (Measurement and Verification) plans are useful for all building types, but high power density projects, such as data centers, will reap significant benefits, as measurement and benchmarking are key steps to improving energy efficiency. This paper specifies a standard for estimating savings from installation of mechanical and electrical systems in data centers, and recommends baselines for modifying or installing energy-efficient equipment in data centers. M&V is the process of using measurement to reliably determine actual savings for energy, demand, and cost within a site by ECMs (Energy Conservation Measures). This paper specifies standardized M&V approaches which target minimizing variations in quality across the analyses, and cover baseline requirements for new construction and retrofit projects and identifies rules.

The environmental control systems used in educational facilities are diverse and obsolete. To provide safety for students and a pleasant learning environment, various systems are installed in learning spaces. In this study, on-site statistical surveys and energy consumption analyses were conducted in ten educational facilities in South Korea. Through awareness surveys of the persons in charge of education facilities, the energy conservation requirements were investigated. The system configuration was generalized according to the energy source, and through this, it was possible to determine the type of system used.

본 연구에서는 공기필터 살균을 위한 UV-C 모듈의 배열에 따른 제균효율에 관하여 실험적 연구를 실시하였다. 본 연구에서는 ASTM F 2101-14 세균여과효율 시험장비를 이용하여 황색포도상구균을 시험용 필터에 분사하고, UV-CC 조사 거리에 다른 제균효율을 실험하였다. 미생물이 분사되 시험용 필터에 UV-C를 2분 조사한 결과 광원과의 거리에 따른 제거효율이 다르게 분석되었다. 공기필터를 살균하기 위해 장착되는 UV-C LED의 설치위치 및 필터에 조사되는 광원의 범위에 따라서도 제균효율은 다르게 나타날것으로 판단된다.

In this study, a new type of non-contact modular screening center (NCMSC) was developed to improve the problems of existing facilities, and an appropriate ventilation system was adapted. Ventilation performance evaluation for efficient virus discharge verified that cross-infection does not occur between a specimen collection both (SCB) and a examination room (ER) by numerical analysis and experiment. As a result of the CFD simulation, after 3,000 virus particles were released from the testees mouth in the SCB, 559 seconds passed, the number of particles remained below about 30, and 99% of the total particles were discharged. SF6 tracer gas was injected for 300 seconds at 0.54 m3/h, assuming the subjects breathing in the SCB. As a result of the tracer gas test, the concentration of SF6 in the SCB was continuously changed in the range of 300-600 ppm, whereas the concentration of SF6 in the ER was not detected within the error range of ±2.0 ppm.
