공군에서 전투기 사고는 적은 비율이지만 계속적으로 발생한다. 이 시스템의 명세 목적은 사람이 결심하여 전투기에서 비상탈출 하는 것에 컴퓨터의 역할을 추가하여 조종사의 생존 가능성을 높이는데 있다. 사람은 모든 감각기관을 통하여 미래의 상황을 예견할 수 있는 능력이 있는 반면, 착각 등을 통하여 실수를 포함하는 행위를 할 수도 있고, 비상탈출을 결심하였다고 하더라도 전투기 기동이 매우 급변하여 반드시 비상탈출을 성공한다고 볼 수 없다. 그래서, 기존에 장치되어 있는 측정장치들을 이용하여, 비 정상적인 워치에 전투기가 위치했을 때는 Warning을 하고, 명백하게 비상탈출 하여야할 겅우가 발생했을 때는 자동으로 비상탈출을 실행하는 System을 명세하였다. AWES(Auto Warning/Ejection System)은 Safety-Critical System의 일종이라 할 수 있다. 그래서, 개발 초기 단계부터 정형기법(format methods)에 기반하여 개발되어야 한다. 본 논문에서는 Reactiv system의 행위적인 면을 명세하는데 장점을 가지는 Statecharts를 이용하였으며, STATEMATE라는 도구로 AWES(Auto Warning/Ejection System)을 명세하였다.

A panic device is a type of door lock that opens when pressed or pushed by the body, so it is an emergency escape device designed to easily open the door and escape in an emergency situation such as fire or earthquake. It is an ideal door handle for an emergency exit. Because many people move quickly and it is easy to use, it is common in Europe and North America, but in Korea, the product is expensive, so it is used on a limited basis in luxury buildings such as hotels, but its use is gradually increasing. East Asian countries such as Korea, China, and Japan mainly prefer the North American type. The design of the penic device used in is a uniform and universal design, and research and development of a new design of the penic device was required to develop a new design type product considering the aesthetics of the building.

Offshore working environments such as ships, offshore oil and gas plants, and offshore wind turbines are isolated and directly exposed to rough seas, which pose high risks of safety accidents. Therefore, all workers in offshore plants should be able to cope with emergency situations and must be qualified according to relevant laws and regulations such as the International Convention on Standards of Training, Certification and Watchkeeping for Seafarers (STCW Convention) and Offshore Petroleum Industry Training Organization (OPITO) standards. In particular, marine workers should be able to perform cardiopulmonary resuscitation (CPR) in isolated locations or enclosed and confined spaces such as those in life-boats, life-rafts, rescue-boats, etc. Because the floor material is made of rubber, it may be difficult to perform chest compressions in life-rafts used to escape from emergency situations in ships or offshore plants. Chest compressions performed on life-rafts may reduce the accuracy of CPR and increase fatigue for those providing aid. To measure the accuracy and fatigue of those performing CPR in life-rafts, 15 experimenters with more than five years of experience as first aid instructors were exposed to different CPR environments in a marine safety training center equipped with an artificial wave generator. The results showed that the accuracy of CPR in the classroom was 99.6 %, but that in various life-raft environments was only 84 %. T-verification of the two sites confirmed the reduced accuracy of CPR performed on life-rafts. CPR on life-rafts should be performed in groups of two and with the use of automated chest compression devices.

Seafarer sea survival training, such as basic safety refresher training and advanced safety refresher training, in accordance with the STCW Convention, is an indispensable program that can increase the crew survival rate during emergency situations at sea. It is important for crew members to carry out theoretical and practical training with various safety equipment in order to effectively train according to IMO model courses. Therefore, this study suggests the following measures to improve safety training facilities for seafarers by reviewing survival training requirements based on the IMO model course and comparing and analyzing related facilities based on operating cases from domestic and overseas training institutes. First, it is necessary to establish a training environment where seafarers can practice utilizing various, updated safety equipment such as marine evacuation equipment (slides, chutes, etc.). Second, it is necessary to construct an educational environment in which learners can directly or indirectly experience realistic emergency situations by installing marine environment simulation facilities with such equipment as a wave generator, rain fall device, wind generating device, etc. Third, it is also necessary to develop and expand customized training using virtual reality equipment in addition to experiential training, audiovisual training and simulation training.
