When the primary function of private security is to protect lives and property of clients, emergency management should be included in the security service and many countermeasure services should be carried out for that purpose. In theses contexts, private security should develop and maintain a educational program to meet their responsibilities to provide the protection and safety of the clients. Conclusionally, private security industry employers in Korea has not concerned with the importance of training and education by lack of recognition and has been passive about qualified guards. And the authorities supervising and the administrating the guards has not recognized the importance of private security and has neglected the training of the guards. In theses contexts, private security should develop and maintain a educational program of emergency management to meet their responsibilities to provide the protection and safety of the clients.

The objectives of this study is to classify evacuation types, derive the characteristics of 4 types, develop and discover evacuation routes within the performance hall space, and present the statistical classification results of the evacuation classification model by classification type. To achieve this purpose, the characteristics of each evacuation type's four types are applied through a network reliability analysis method and utilized for institutional improvement and policy. This study applies for the building law, evacuation and relief safety standards when establishing a performance hall safety management plan, and reflects it in safety-related laws, safety standards, and policy systems. Statistical data by evacuation type were analyzed, and measurement characteristics were compared and analyzed by evacuation types. Evaluate the morphological similarity and reliability of evacuation types according to door width and passage length and propose the install position of evacuation guidance sign boards. The results of this study are expected to be used as basic data to provide operation strategies for safety facility evacuation information sign boards according to evacuation route classification types when taking a safety management plan. The operation strategy for the evacuation sign boards installation that integrates employee guidance and safety training is applied to the performance hall safety management plan. It will contribute to establishing an operational strategy for performance space safety when constructing performance facilities in the future.

Safety education delivered to construction workers in a lecture manner has limitations in concentration and immersion, so delivery power and interest are low. In order to improve unstable behavior through education and prevent safety accidents, it is necessary to change the paradigm to hands-on education. Purpose: Experiential safety education aims to contribute to preventing accidents for construction workers by quickly recognizing risks, improving emergency response skills, and verifying the effectiveness of pre- and post-learning. Method: Based on a survey of workers who experienced the same work environment as the actual construction site, an opinion survey on the pre- and post-safety experience education and a variable measurement tool were planned, and a research hypothesis was established. Results: The Bayesian theory and MC simulation analysis were used to analyze the structural equation model, and the change in construction worker behavior was confirmed through the intended safety (A), non-experiential education in the sub-area of anxiety (B), average, standard deviation, and minimum and maximum values. Conclusion: The effect of education and industrial accidents are reduced only when construction workers are motivated to participate.

Radiography-Testing that verify the quality of welding structures without destruction are overwhelmingly used in industries, but many safety precautions are required as radiation is used. The workers for Radiography-Testing perform the inspection by moving the Iridium-192 radiation source embedded in the transport container of the gamma-ray irradiator within or outside the facility. The general facility is completely blocked about radiation from the outside with thick concrete, but if it is difficult for worker to handle object of inspection, facilities ceiling can be opened. A general facility may be constructed using a theoretical dose evaluation method because all exterior facilities are blocked, but if the ceiling is open, it is not appropriate to evaluate radiation safety with a simple theoretical calculation method due to the skyshine effect. Therefore, in this study, the radiation safety of the facility was evaluated in the actual field through an ion chamber survey-meter and an accumulated dose-meter called as OSLD, and the actual evaluation environment was modeled and evaluated using the Monte Carlo simulation code as FLUKA. According to the direction of the irradiation, the radiation dose at the facility boundary was difficult to meet the standards set by the regulatory authority, and radiation safety could be secured through additional methods. In addition, it was confirmed that the simulation results using the Iridium-192 source were valid evaluation with the actual measured results.

국내외 발생하는 재난 중 70% 이상이 물과 관련된 재해로 분류되며, 집중호우와 태풍으로 인한 하천범람 및 내수침수 등으로 많은 피해를 발생시키고 있다. 특히 최근 발생하는 피해 양상은 과거에 발생하지 않았던 극한 강우로 인해 돌발적으로 발생하는 경우가 빈번하게 발생하고 있어 이에 따라 사전에 예측하여 미리 대비하는 선제적인 홍수 대비 시스템이 요구되고 있다. 선제적인 홍수 대비 시스템의 구축 여부는 정확한 하천 흐름 예측을 필요로 한다. 하지만 하천의 흐름은 댐붕괴, 제방붕괴, 하천 하상의 변동 등 다양한 상황에서 급격한 흐름의 변동이 발생하며, 이는 하천 흐름 예측에 장애물로 작용하여 정확도를 떨어뜨리는 요인이 된다. 특히 국내에는 산악지형과 수공구조물에 의한 불연속 단면이 다수 존재하고 있어 그 예측 결과에 대한 정확성에 대한 요구가 더욱 부각되고 있다. 그렇기 때문에 해당 문제를 해결하기 위한 다양한 기법들이 개발되어 실무에 적용되고 있으나 어떤 기법이 국내 하천특성에 적합한지 파악할 수 없으며, 그 정확성과 안정성에 측면에서 여전히 많은 문제점을 가지고 있는 실정이다. 본 연구에서는 불연속 흐름이 빈번하게 발생하는 국내 하천 특성에 적합한 수치 기법을 확인하고자 유량보존특성을 만족하는 유한체적기법 중 국내외적으로 다수 사용되었던 기법들을 비교 및 평가하였다. 불연속 흐름의 대표적인 예제로서 'Dam-break problem'과 충격파 해석 및 홍수기와 갈수기에 따른 하천 하상의 마름/젖음에 대한 평가를 할 수 있는 Toro's Riemann problems에 적용하여 비교하였으며 그 결과 값을 정량적인 수치로 나타내었다. 이를 통해 국내 하천 특성에 적합한 수치 기법을 선정하였으며. 향후 국내하천 환경을 만족할 뿐만 아니라 하천 종사자들의 요구에도 부합한 하천흐름해석 모형의 개발 시 많은 기여가 될 것이라 판단된다.
