As remote sensing and GIS have been considered to be essential technologies for disasters information production, researches on developing methods for analyzing spatial data, and developing new technologies for such purposes, have been actively conducted. Especially, it is assumed that the use of remote sensing and GIS for disaster management will continue to develop thanks to the launch of recent satellite constellations, the use of various remote sensing platforms, the improvement of acquired data processing and storage capacity, and the advancement of artificial intelligence technology. This spatial issue presents 10 research papers regarding ship detection, building information extraction, ocean environment monitoring, flood monitoring, forest fire detection, and decision making using remote sensing and GIS technologies, which can be applied at the disaster prediction, monitoring and response stages. It is anticipated that the papers published in this special issue could be a valuable reference for developing technologies for disaster management and academic advancement of related fields.

Recently, a building fire has occurred due to various influences. Accordingly, we are developing an public safety & security unmanned aerial vehicle for fire prevention and initial response to fire. The public safety & security unmanned aerial vehicle is used to grasp the traffic route to enter the fire engine in the event of a fire in a dense structure and to determine the scale of the fire and the area of danger of collapse around the fire site. In this study, an environmental test of the public safety & security unmanned aerial vehicle's heat resistance was performed in an environment simulating a fire scene.

Purpose: This thesis is to measure construction working environment and to improve health protection of site workers, who are required to take special health check, by analyzing harmful factors that are occurred by each site operation. Method: This thesis explicates the analysis of harmful factors per the operation at construction site, the target of working environment measurement with examined harmful factors, and the variables of special health check. Result: This thesis figures out the target of working environment measurement and the variables of special health check through the analysis of harmful factors per the operation from 12 construction projects. Conclusion: This This thesis is expected to be an instrument for preventing construction site workers from occupational disease, by regular execution of measuring working environment via harmful factors of each operation as well as of special health check.

Purpose: This study aims to support the dispatcher to analysis the architecture type of fire. Method: Analysis the dispatch protocol guideline (released by gyunggi fire brigade) and make the dispatch scenario by site, combustibles, evacuation, fire extinguish systems. Result: After making scenario, develop the system (for dispatcher), is based on the tablet PC. Conclusion: Dispatch systems apply not only fire but rescue and disaster. This study focus on the fire, but It is need to expend the rescue and disaster. in korea, Fire Safety Evaluation and Multishop DB are possible to link to this system.

과거의 우리나라 대설피해 양상을 살펴보면 지역적으로 집중되어 피해가 발생하는 것이 특징이다. 그러나 현재는 전국적으로 대설피해가 가중되는 추세이며, 이에 따라 대설피해에 대비 가능한 대책의 강구가 필요한 실정이다. 그러나 피해 발생 시 정확한 피해 예측으로 사전에 재난을 대비가 가능한 수준의 연구는 미흡한 실정이다. 따라서 본 연구에서는 다양한 통계기법과 기계학습 기법을 이용하여 대설로 인해 발생한 피해액을 개략적으로 예측이 가능한 모형을 개발하고자 하였다. 대설피해액 예측 모형은 다중회귀분석, 서포트 벡터 머신, 인공신경망 기법, 랜덤포레스트 기법을 이용하여 총 4가지 기법으로 개발하였으며, 독립변수로 사회·경제적 요소, 기상요소를 사용하였고, 종속변수로는 1994년부터 2020년까지 발생한 대설피해 이력의 대설피해액을 사용하였다. 결과적으로 4가지 예측 모형의 예측력 검증 및 기법 간의 예측력을 비교하여 개발한 모형의 적용성을 검토하였다. 본 연구 결과에서 제시한 모형의 개선방안 및 업데이트 방안을 참고하여 후속 연구가 진행된다면 미래에 전국적으로 확대될 대설피해에 대한 대비가 가능할 것으로 기대되며 복구비 및 예방비 투자의 지역적 우선순위를 분석하여 선제적인 대비가 가능할 것으로 판단된다.

Today's high-rise buildings are increasing concern about the safety and evacuation of people related to the fire and threat from outside. Terrorism breaking out in high-rise buildings, a symbol of the national economy results in a number of casualties, economic loss, social fear and damage to national status. That's why high-rise building has also emerged as a target of major terrorist attacks, compared to other types of buildings. We have 54 high-rise buildings in 15 regions over the country. The Ministry of Land, Infrastructure and Transport and Seoul Metropolitan Government have offered the guidelines to prevent terrorist attacks toward high-rise buildings. Since the 9/11 terrorist attacks, the U.S. Federal Emergency Management Agency (FEMA) has developed and taken advantage of the Risk Management Manual Series. According to this manual, pre-assessment is conducted for the prevention of terrorism and particularly in FEMA 455, risk of the surrounding areas, vulnerability, possibility from terrorist attacks are checked. After the check, experts classify the risk of terrorist attacks toward the high-rise buildings and according to the risk classification, architects, security experts and structure engineers can carry out terrorism prevention program for high-rise buildings. The U.K. NaCTSO has also offered the terrorism prevention guidelines. Therefore, the Ministry of Land, Infrastructure and Transport and Seoul Metropolitan Government should make more concrete guidelines for high-rise buildings such as what U.S. FEMA and U.K. NaCTSO implement, including prior evaluation technique for terrorism risk.

Abnormal weather conditions have lately been occurring frequently due to the rapid economic development and global warming. Natural disasters classified as storm and flood damages such as heavy rain, typhoon, strong wind, high seas and heavy snow arouse large-scale human and material damages. To minimize damages, it is important to estimate the scale of damage before disasters occur. This study is intended to develop a strong wind damage estimation function to prepare for strong wind damage among various storm and flood disasters. The developed function reflects weather factors and regional characteristics based on the strong wind damage history found in the Natural Disaster Yearbook. When the function is applied to a system that collects real-time weather information, it can estimate the scale of damage in a short time. In addition, this function can be used as the grounds for disaster control policies of the national and local governments to minimize damages from strong wind.

1983년 10월 원대한 포부와 중차대한 사명감 아래 여주벌에서 첫 삽을 뜨며 출발한 국내 최초의 방재시험소가 마침내 건축공사를 끝내고 본격적인 업무개시를 눈앞에 두고 있다. 화재로 인한 각종 재난을 빈번히 겪으면서도 과학적으로 대처하지 못한 채 되풀이 되는 대형 참사에 속수무책이었던 우리 현실로서는 획기적인 발전이 아닐 수 없다. 우리보다 앞선 여러나라에 비해 조금도 손색없는 장비와 인력을 갖추고 최첨단을 향한 방재활동의 첫 발을 내디디며 무한한 긍지를 느낀다.

Existing efforts to reduce total egress time actually focused on reducing travel time. However, consideration to reduce perception time or response time was insufficient although the ratio of travel time is one-third of total egress time and situations which the safety cannot be ensured by only reducing travel time were aroused. Therefore, the concept of disaster information, which could reduce both perception time and response time got attention To analyze the effect of disaster information on occupant behaviour, this study identified a relationship between 10 major disaster information and 3 occupant behaviour factors in terms of reducing egress time. By referring the relationship, this study conducted an virtual egress experiment with survey on 4 cases, the elderly, intellectual disabled, hearing disabled and visual disabled, to identify disaster information which reduce total egress time effectively. Finally, by analyzing the experiment result, this study proposed the process of disaster information effect on occupant behaviour as complementing insufficient occupant behaviour to ensure the minimum level of safety and maximizing relatively high occupant behaviour to ensure enough level of safety. The results are expected to account for relationship between disaster information and occupant behaviour with more explanatory power in terms of egress time. With further studies of disaster information and group behaviour, these series of studies could provide basic references for disaster information and occupant behaviour.

The purpose of this study is to establish a system that manages the safety of buildings efficiently by finding the correlation of elements related to the safety of buildings and intuitively visualizing them. Data were collected using the data of small-scale buildings managed by public institutions and the government, and an effective analysis visualization environment was established through pre-processing. We selected safety-vulnerable factors such as the structure of the building and completion date to find the relationship, and established a model to prioritize management to find vulnerable buildings.
