기존 등부표, 등명기 점검 시 사다리를 타고 상단에 올라가서 등명기를 점검하며, 너울성 파도 등으로 인하여 등부표가 기울어질 경우 추락사고가 발생할 수 있어 이를 예방하기 위해 엘리베이터 폴을 적용하여 등명기를 표체까지 하강시켜 안전하고 용이하게 점검할 수 있는 시스템 개발에 관한 것이다. 또한, 강철로 제작하는 표체를 탄소섬유로 제작하여 경량화하고 침추 무게, 투입 해상장비의 규모를 줄여 공사비를 절감하는 기대효과를 가질 수 있다.

Safety accidents at industrial sites can occur anytime, anywhere. Recently, research on the industrial safety management system based on the IoT has been actively conducted. However, most of the studies are studies of actions after safety accidents or simply monitoring. In this paper, the safety equipment was introduced before safety accidents occurred, and the subjects could be managed not only by workers but also by visitors. Also, it implements a system to prevent the accident by detecting the user's motion and situation periodically before a safety accident occurs. The implemented system is a system that attaches the device for safety management to the hard hat and can identify the safety situation by using the Bluetooth beacon device attached to the user's smartphone and the industrial site.

Even thought modernized marine navigation devices help navigators, marine accidents has been often occurred and ship collision is one of the main types of the accidents. Various studies on the assessment method of collision risk have been reported, and studies using fuzzy theory are remarkable for the reason that reflect linguistic and ambiguous criteria for real situations. In these studies, collision risks were assessed on the assumption that the current state of navigation ship would be maintained. However, navigators ignore or turn off frequent alarms caused by the devices predicting collision risk, because they think that they can avoid the collisions in the most of situations. This paper proposes a model of predicting ship collision risk considering the general patterns of collision avoidance, and the approach is based on fuzzy inference and discrete event system specification (DEVS) formalism.

As the spread of DC power distribution systems increases, the occurrence of failures and fire accidents are also increasing. In particular, the ESS fire accident, which is a component of the smart grid, and the fire accident of the solar power system, which is a direct current system, are caused by problems in the electrical connection between system components as the supply of new and renewable energy rapidly increases and old facilities increase. An arc that can cause a direct fire by releasing the induced light and heat has been pointed out as one of the causes of fire. Therefore, the problem of such an arc defect is that it is impossible to block an arc accident in advance with the existing overcurrent circuit breaker and earth leakage circuit breaker. In this paper, we intend to develop a test equipment that satisfies international standardization and to develop a DC arc generator to protect against failure and fire caused by arcing.

Recently, as more and more cyclists ride bicycles for their health and more people commute by bicycle, the number of cyclists has increased. However, as the number of users increases, many accidents occur, and the handling of bicycle accidents is unstable. It is inadequate to prepare for accidents in other ways except for safety equipment. Therefore, there is a need for a safe and convenient way for modern adults to ride. Unlike other apps, in this study, by adding a safety function, you can shoot a black box while riding, and a function to inform you that it is an accident-prone area is implemented. In addition, a function that can detect an accident using the Android built-in sensor and automatically make emergency contact is added. Cyclists can secure safety and convenience in one app without the need to use additional apps. Furthermore it develops an app system that allows you to talk about riding and share your route through the Riding Community bulletin board.

With an entry into force of OPRC-HNS on June 14th 2007, response system against any large scale accidents related to HNS is required to respond rapidly and effectively in a national scale, US national response system and national contingency plan for any chemicals in operation were analyzed to understand the characteristics of management system and response system for any HNS driven accidents in the Us. Main characteristics of the US system were well described as an unified information window and an integrated incident command system supported by response facilities, manpower and technical support from other response organizations through good cooperation. In general, response activities are conducted by private sectors, however, the government will take over response activities in case large scale accidents occur in the Us. Expected expenses for response activities are covered by a type of Superfund in the Us. Several applicable ways are proposed to enable NGO to participate in and reorganize response system in ROK, and are feasible in collaboration with other response organizations and private sectors in the aspects of equipment, technology and manpower, Based upon the above activities, it is desirable to reorganize domestic rules and/or regulations related to response measures in ROK.

The need for education and training on engine-part maintenance is rising in order to prevent marine accidents occurring due to a surge in engine-part damages. However, practical training using actual equipment is difficult due to the size and location of the equipment. Therefore, the necessity of developing a training system for marine engines using virtual reality (VR) is intensifying. The purpose of this paper is to develop an optimized system for marine engine education and training using existing VR programs and equipment. To this end, we selected and modeled the marine engine and education target suitable for the class, and developed the system using VR development software. The developed VR education and training system is designed to experience content that is otherwise difficult to train or practice in the curriculum through virtual reality. In fact, fourth grade students from Maritime University were taught using marine engine VR educational equipment, and it confirmed that there was an educational effect on the class. In the future, the introduction of an education and training system using VR in the field of marine engines can improve their maintenance and repairing capacity, and aid in reducing marine accidents.need for education and training on engine part maintenance is increasing to prevent marine accidents.

National Institute of Environmental Research has Portable FT-IR(Fourier Transform Infrared Spectroscopy, A2 Technologies, U.S.A.) and Portable XRD(X-ray Diffraction, Olympus Innov-X co., U.S.A.) for the analysis of the solid sample rapidly on the spot where chemical terror accident took place and the portable equipments are operating now. However, we need a series of the analysis procedures for an efficient application of the equipments and getting the rapid analytical value about the investigation and sampling on the spot. And the accuracy of the portable equipments' analytical value is high but the application of them in an emergency is low because we are lack of the procedures about field-centered analysis and the usage. Therefore we would like to organize the result of this research about field analysis and the procedures of the solid portable equipments. And we also would like to apply it to the field of chemical terror accident.
