This study was conducted to develop precision control system fur cold storage facility that could offer safe storage environment for green grocery. For that reason of neuro-fuzzy control system with learning ability algorithm and single chip neuro-fuzzy micro controller was developed for cold storage facility. Dynamic characteristics and hunting of neuro-fuzzy control system were far superior to on-off and fuzzy control system. Dynamic characteristics of temperature were faster than on-off control system by 1,555 seconds(123% faster) and fuzzy control system by 460 seconds(36.4% faster). When system was arrived at steady state. hunting was ${\pm}$0.5$^{\circ}C$ in on-off control system, ${\pm}$0.4$^{\circ}C$ in fuzzy control system, and ${\pm}$0.3$^{\circ}C$ in neuro-fuzzy control system. Hunting of humidity and wind velocity was also controlled precisely by 70 to 72.5% and 1m/s For storage experiment with onion, characteristics of neuro-fuzzy control system were tested. Dynamic characteristics of neuro-fuzzy control system made cold storage facility conducted precooling ability and minimized hunting.

The school is the educational and living space for students and teachers. And, the safety of the school facilities is very important element on the school activities. For this safety of school facilities, there is a need to prevent of safety-accident by the reinforcement of the systematic and the removal of risk factors. In order to minimize the damages from school facilities this study tried to suggest the solution for the prevention of safety accidents according to research about actual conditions of safety accidents from school facilities.

시설물의 유지관리란 시설의 구조적, 기능적, 미적성능을 보전하는 것이다. 이를 통하여 시설물을 이용하는 사람들의 일상적인 편의와 안전을 확보할 수 있도록 하여야 한다. 그러나 준공당시의 시설물은 시간이 지남에 따라 노후화되고 초기의 기능을 확보하는데 어려움을 갖게 된다. 현재 시 도교육청은 학교시설물의 유지관리를 비롯한 점검 및 관리를 형식적으로 수행하고 있어 재난발생위험에 적기대응이 곤란하고, 학교 시설에 대한 안전대책의 수립이 지연되는 등 관리가 부실한 실정이다. 또한 교육환경개선비가 배분기준과 달리 산정되는 등 비합리적으로 결정되고 있다. 이에 본 연구는 수많은 초 중등학교 시설물에 적용할 수 있는 동일하고 단순한 정량적 지표와 방법을 개발하여 객관적으로 학교 시설물의 노후도를 판단할 수 있는 방안을 제안하고 사례 연구를 통하여 검증하였다.

In Singapore, biosafety and biosecurity measures are controlled by the Biological Agents and Toxins Act (BATA) and other requirements by regulatory agencies. The law prohibits and otherwise regulates the possession, use, import, transhipment, transfer, and transportation of biological agents, inactivated biological agents, and toxins that are of public health concern. The law also defines the facility requirements for high risk biological agents and toxins. The containment facility (BSL 3) is a minimum requirement to handle biological agents that falls under Schedule 1 (Risk Group 3). The Nanyang Technological University School of Biological Sciences Biosafety Level 3 Facility (NTU-SBS BSL 3) was designed specifically for research involving potential hazardous biological materials. The facility requires yearly re-certification by an approved facility certifier to meet the local requirements and international biosafety standards for a containment facility in many instances. On the other hand, most NTU researchers conduct biological projects involving biological agents with low or moderate risk groups (Risk Groups 1 and 2 or biological agents described in schedule 3 and 4 of BATA) and GMOs, which need only a BSL 2 laboratory. BSL 2 laboratories are yet to be legally certified or registered in Singapore. Institutional Biosafety Committee (IBC) identifies the requirements; defines a minimum standard in the safe control of biological risks and registers all BSL 2 laboratories in the NTU. Therefore, under the guidance of the IBC, the University Biosafety and Biosecurity Programme includes the audit and certification program as a unique and an internal exercise to bring NTU biosafety to a higher level.

This study analyzes the effects of personal lockers, drinking fountains, and all-in-one shutters (hereinafter referred to as "corridor walking obstacles") on evacuation safety to suggest the necessity of operating a more effective educational facility safety certification system. To achieve this purpose, the five-story high school building with the obstacles installed in the corridor has been chosen, and evacuation tests through the Pathfinder Simulation Program have been carried out. When the evacuation exit is designated in the current state, where the students are placed on the 2nd, 3rd, and 4th floors and the corridor walking obstacles are applied as a variable, the required safe egress time (RSET) is 322 seconds. This can lead to dangerous results in the event of a disaster by exceeding the available safe egress time (ASET) standard of 240 seconds by 82 seconds. When students are placed on the 1st, 2nd, and 3rd floors under the same conditions, the RSET is 214.5 seconds, 25.5 seconds lower than the ASET standard, indicating that it is effective in reducing the impact of walking obstacles on evacuation time. The safety management plan for walking obstacles in the corridors is discussed, considering the special characteristics of the school corridors. The results of this study can be used as the necessary data for optimizing evacuation routes in corridors and creating a safe, educational environment.

The deaths caused by industrial accidents during the construction of the mortality rate is considerably higher than in other industries. To prevent such a disaster workers and to minimize unsafe behavior measures to be drawn, and construction companies recently to stimulate the emotions of the workers to participate in voluntary activities are safe. In this study, the construction workers can stimulate emotions and activities on the environment by examining the preferences of the workers on-site management will want to take advantage. This study revealed that the construction workers prefer the incentive most and then working environment.

This study is on safety improvement measures through analysis of accident cases during plant storage tank construction. Storage tank is a general term for artificial ground facility constructed to store oil, water, gas, and other chemicals. Some companies have clustered storage tanks (tank farm). The construction methods vary according to the component and types of fluids. Because most of the construction procedures include lifting heavy weight materials using heavy construction equipment and are carried out at high places, storage tank construction contains more risk factors than normal aerial construction. Recently, major accidents such as storage tank collapse have occurred often, and cost many lives due to the characteristics of the structure. In this study we would like to analyze the cause of these accidents and propose measures to improve safety.

안전하고 쾌적한 교육환경 조성 및 교육 질 향상을 위하여, 2021년 「교육시설 등의 안전 및 유지관리 등에 관한 법률」이 제정되었다. 이에 따라 「교육시설 안전 인증 운영 규정」이 수립되었으며, 유치원, 초·중·고등학교 및 특수학교, 대학 및 기타 교육시설의 특성에 따라 3가지 유형으로 분류되어 평가되어진다. 기타 교육시설에는 도서관, 학생수련원이 포함된다. 하지만, 학생수련원, 도서관은 수련, 독서 등의 특수 활동이 발생하는 시설로 학교와 차이점을 두고 있다. 때문에 학생수련원 도서관 시설만의 특수성이 「교육시설 안전 인증 운영 규정」에 반영될 필요가 있다. 이 연구는 기타시설에 해당되는 학생수련원과 도서관의 특수성을 「교육시설 안전 인증 운영 규정」이 어떻게 반영하고 있는지에 대한 분석이 수행되었다. 선행 인증제도 및 가이드라인과 비교 분석되었으며, 현장 조사방법이 이용되었다. 최종적으로 도서관과 학생수련원에 대하여 각각 9가지의 세부 기준 검토가 필요한 것으로 확인되었다.
