The purpose of this study is to strengthen the capability of rapid mapping for disaster through improving the positioning accuracy of mapping and fusion of multi-sensing point cloud data derived from Unmanned Aerial Vehicles (UAVs) and disaster investigation vehicle. The positioning accuracy was evaluated for two procedures of drone mapping with Agisoft PhotoScan: 1) general geo-referencing by self-calibration, 2) proposed geo-referencing with optimized camera model by using fixed accurate Interior Orientation Parameters (IOPs) derived from indoor camera calibration test and bundle adjustment. The analysis result of positioning accuracy showed that positioning RMS error was improved 2~3 m to 0.11~0.28 m in horizontal and 2.85 m to 0.45 m in vertical accuracy, respectively. In addition, proposed data fusion approach of multi-sensing point cloud with the constraints of the height showed that the point matching error was greatly reduced under about 0.07 m. Accordingly, our proposed data fusion approach will enable us to generate effectively and timelinessly ortho-imagery and high-resolution three dimensional geographic data for national disaster management in the future.

Cooperation between government agencies is important for disaster management, and a thorough and objective cause investigation is important to prevent the recurrence of similar disasters. In South Korea, individual laws are scattered by ministries according to the disaster type, and most are operated as non-permanent organizations that are employed when disasters occur. Although expertise is recognized for each disaster type, each government agency's operation method is different, so when a large-scale disaster involving multiple ministries occurs, there is a limit to the coordination of roles and integrated management between government agencies. In particular, whenever a large-scale complex disaster occurs, problems arise regarding the independence, professionalism, and fairness of the cause investigation. Therefore, to supplement this, reviewing the management methods and systems of disaster cause investigations in advanced countries is necessary. Thus, in this study, the organization status, manpower, organizational structure, and cause investigation work system of NTSB of the United States, JTSB of Japan, and SHK of Sweden are identified to improve the disaster cause investigation system in Korea and are compared and analyzed with Korea's GDCIG. Additionally, issues and problems for the advancement of Korea's disaster cause investigation system are considered and improvements are suggested.

In this study, we explored a method for assessing the extent of damage caused by chemical substances at an accident site through the use of a vegetation index. Data collection involved the deployment of two different drone types, and the damaged area was determined using photogrammetry technology from the 3D point cloud data. To create a vegetation index image, we utilized spectral band data from a multi-spectral sensor to generate an orthoimage. Subsequently, we conducted statistical analyses of the accident site with respect to the damaged area using a predefined threshold value. The Kappa values for the vegetation index, based on the near-infrared band and the green band, were found to be 0.79 and 0.76, respectively. These results suggest that the vegetation index-based approach for analyzing damage areas can be effectively applied in investigations of chemical accidents.

High-resolution satellites capable of observing the Earth periodically enhance applicability of remote sensing in the field of national disaster management from national disaster pre-monitoring to rapid recovery planning. The National Disaster Management Research Institute (NDMI) has been developed various satellite-based disaster management technologies and applied to disaster site operations related to typhoons and storms, droughts, heavy snowfall, ground displacement, heat wave, and heavy rainfall. Although the limitation of timely imaging of satellite is a challenging issue in emergent disaster situation, it can be solved through international cooperation to cope with global disasters led by domestic and international space development agencies and disaster organizations. This article of special issue deals with the scientific disaster management technologies using remote sensing and advanced equipments of NDMI in order to detect and monitor national disasters occurred by global abnormal climate change around the Korean Peninsula: satellite-based disaster monitoring technologies which can detect and monitor disaster in early stage and advanced investigation equipments which can collect high-quality geo-information data at disaster site.

Seamless wireless communication network access technology enables users to guarantee service continuity. Hence, it is necessary for disaster situations in which network service may be interrupted. The Multi-path router is a technology to improve network stability and strengthen field operability, particularly in a disaster environment where network failure can occur by providing high-performance data transmission using multi-communication networks and network security by VPN-based wireless IP. In this paper, a prototype system for an MPR-based wireless communication network was proposed to improve the operation performance for disaster field investigation applications. A comparative experiment was performed on various data transmission performances with the existing single wireless communication network. In addition, another experiment was conducted by measuring the data packet transmission and receiving performance in the existing/new wireless communication system first and then assessing the UDP transmission performance in a single router environment to understand the transmission capability of the new MPR. The experimental results showed that the sending and receiving performance was improved by approximately double that of the existing single wireless communication system. The proposed prototype system is expected to allow users to share and disseminate collected on-site data more quickly and efficiently during a disaster site investigation.

대한민국은 노인인구 증가와 출생율 감소로 인해 생산인구가 고령화되고 있으며 청장년 근로자에 비해 상대적으로 신체적, 심리적으로 산업재해에 취약한 중고령 근로자의 안전은 재해율을 상승시키는 주요 원인으로 꼽힌다. 본 논문에서는 근로자건강검진을 표본으로 하여 신체기능의 특징과 심신기능 변화에 따른 중대재해 원인을 파악하고 재해예방 3E 이론에 따른 대책을 마련하여 건설현장 중고령 근로자의 재해예방 방법을 구축하였다. 분석결과를 토대로 기술적인 측면에서 추락재해예방을 위한 안전난간, 다기능성 강선형 비계, 수직비계 등의 개발을 통해 위험 작업을 간소화하여 재해 가능성을 낮추는 방법을 도출하고 관리적 측면에서 재해정보 관리시스템을 통한 재해정보 관리방안을 제시하였다. 또한, 교육적인 방법으로는 중고령 근로자만을 대상으로 하는 별도의 특별교육과 감독을 제안하였다. 본 연구를 지속적으로 발전시켜 효율적이고 체계적인 안전관리대책을 마련한다면 건설재해예방에 크게 기여할 것이다.
