Purpose: This study aimed to develop an emerging infectious disease (COVID-19) simulation module for nursing students and verify its effectiveness. Methods: A one-group pretest-posttest quasi-experimental study was conducted with 78 under-graduate nursing students. A simulation module was developed based on the Jeffries simulation model. It consisted of pre-simulation lectures on disaster nursing including infectious disease pandemics, practice, and debriefings with serial tests. The scenarios contained pre-hospital settings, home visits, arrival to the emergency department, and follow-up home visits for rehabilitation. Results: Disaster preparedness showed a statistically significant improvement, as did competencies in disaster nursing. Confidence in disaster nursing increased, as did willingness to participate in disaster response. However, critical thinking did not show significant differences between time points, and neither did triage scores. Conclusion: The developed simulation program targeting an infectious disease disaster positively impacts disaster preparedness, disaster nursing competency, and confidence in disaster nursing, among nursing students. Further studies are required to develop a high-fidelity module for nursing students and medical personnel. Based on the current pandemic, we suggest developing more scenarios with virtual reality simulations, as disaster simulation nursing education is required now more than ever.

Purpose: The study aimed to examine the effects of disaster nursing simulation training on attitudes toward disaster management, disaster preparedness, learning self-efficacy and nursing practice satisfaction in nursing college students. Methods: The study is based on a one-group pretest-posttest design. A total of 95 nursing students were recruited from a nursing college. Disaster nursing simulation training for fire and earthquake situations were provided for 8 hours in one day. Results: There were significant differences in nursing students' attitudes toward disaster management (t=2.20, p=.030), disaster preparedness (t=7.88, p<.001), learning self-efficacy (t=3.69, p<.001), and nursing practice satisfaction (t=5.28, p<.001). Conclusion: Based on our findings, it is necessary to implement disaster nursing simulation training to improve disaster nursing competency of college students.

Our country's coast is vulnerable area to natural disaster which the repetitive damages occur every year including a loss of lives, the damage of facilities and erosion mostly except for the east coast because of a typhoon, tidal waves, sea water overflowing by topographic structure of low-lying gentle slope and shallow sea. However, as for prevention of natural disaster occurring every year, the situation is that it's centered on the restorationcentered measures and the general disaster prevention research to minimize damages at the time of disaster occurrence is insufficient. This study intendedlop t to devehe techniques possible for real time sampling of damage prediction areas on Web in order to support decision making for damage prevention and establishment of disaster prevention policy. For this, the thematic map was produced related to disaster based on high-resolution satellite picture, and the environmental DB similar to real world was constructed through topographic construction of three-dimension integrating the parts of land and the sea. In addition, the system was developed possible for the expression of damageable regions by real time grasp of dangerous regions at the time of disaster occurrence through over flowing simulation of three-dimension, and it's intended to prepare a basis to minimize damages to disaster situations through it.

In recent years, the scale of damage from disasters such as earthquakes and large-scale fires and floods that are occurring in Korea is increasing. Accordingly, interest in urban disaster prevention that combines living infrastructure such as roads and parks is boosting, and it is urgent to prepare measures to reduce the damage scale of local cities. The purpose of this study is to derive implications for disaster prevention measures in areas where disaster prevention safety of local cities is weak through examples of disaster prevention safety of local cities in case of disaster. To this end, this study analyzed the regional characteristics, current status, and disaster prevention problems of regional cities in Japan, and selected disaster-vulnerable areas, and considered the distance relationship between disaster prevention bases through road network analysis. In addition, road closure simulation using ArcGIS Network Analyst was conducted to analyze disaster prevention safety in the area. As a result, the situation of the village which has a high possibility of isolation by natural disasters was grasped in advance. Through this, the suburbs confirmed the necessity of supplementing the disaster prevention function through transportation maintenance such as forest roads, and it was found that the city needs to prepare a risk management system. Furthermore, this study suggests the need for research on areas with a high possibility of isolation, especially in areas where disaster prevention functions are weak in local cities in case of disaster, and shows countermeasures for disaster prevention measures and resident education.

최근 AR기술을 접목한 UAV 기반 재난구조 시스템이 연구되고 있다. 일반적으로 실제 재난 현장과 유사한 환경에서 재난 구조 훈련을 진행하는 것은 높은 비용과 사고 위험이 야기된다. 본 논문에서는 AR 기술을 접목한 UAV 기반 재난구조 시스템의 운용을 구조요원이 저렴하고 안전하게 훈련할 수 있도록 VR 기술을 이용한 훈련 시뮬레이션 소프트웨어를 제안한다. 기존 시스템의 분석을 통하여 훈련을 가상화하기 위한 요구사항을 도출하고 Unreal Engine 및 Airsim API를 이용하여 제안하는 시뮬레이션 소프트웨어를 개발한다. 모의실험은 제안하는 시뮬레이션 소프트웨어가 기존 재난구조 플랫폼의 동작을 효과적으로 모의할 수 있음을 보여준다.

강화학습은 학습을 통해 최적의 행동정책을 탐색하는 기법으로써, 재난 상황에서 효과적인 인명 구조 및 재난 대응 문제 해결을 위해 많이 활용되고 있다. 그러나, 기존 재난 대응을 위한 강화학습 기법은 상대적으로 단순한 그리드, 그래프와 같은 환경 혹은 자체 개발한 강화학습 환경을 통해 평가를 수행함에 따라 그 실용성이 충분히 검증되지 않았다. 본 논문에서는 강화학습 기법을 실세계 환경에서 사용하기 위해 기존 개발된 재난 시뮬레이션 환경의 복잡한 프로퍼티를 활용하는 강화학습 환경 구성과 활용 결과를 제시하고자 한다. 본 제안 강화학습 환경의 구성을 위하여 재난 시뮬레이션과 강화학습 에이전트 간 강화학습 커뮤니케이션 채널 및 인터페이스를 구축하였으며, 시뮬레이션 환경이 제공하는 고차원의 프로퍼티 정보의 활용을 위해 비-이미지 피쳐 벡터(non-image feature vector)에 이미지 변환방식을 적용하였다. 실험을 통해 본 제안 방식이 건물 화재 피해도를 기준으로 한 평가에서 기존 방식 대비 가장 낮은 건물 화재 피해를 기록한 것을 확인하였다.

A*algorithm is highly useful to search the shortest route to the destination in the evacuation simulation. For this reason, A*algorithm is used to evaluate the evacuation experiment by the computer simulation. However there are some problems to analyze the outcome in relation to the reality. Because all the people in the building are not well-informed of the shortest route to the exit. And they will not move to the disaster spot though it is shortest route to the exit. Therefore, evacuation simulation program based on A*algorithm raise a problem of bottleneck phenomenon and dangerous result by damage surrounding the disaster spot. The purpose of this research is to prove the necessity for dispersion evacuation simulation by Multi agent system to solve the problems of the existing evacuation simulation program based on A*algorithm.

For safe evacuation in the fire disaster, the evacuees must find the exit and evacuate quickly. Especially, if the evacuees don't know the location of the exit, they have to depend on the evacuation guidance system. Because the more smoke spread, the less visibility is decreasing, it is difficult to find the way to the exit by the naked eye. For theses reasons, the evacuation guidance system is highly important. However, the evacuation guidance system without change of direction has the risk that introduce to the dangerous area. In the evacuation safety assessment scenario by the evacuation simulation has the same problem. Because the evacuee in the simulation evacuate by the shortest route to the exit, the simulation result is same like the evacuation without the evacuation guidance system. In this study, it was used with MAS (Multi Agent System)-based simulation program including the evacuation guidance system to implement the change of evacuation by fire. Using this method, confidence of evacuation safety assessment can be increase.
