In the event of a disaster, we need people who specialize in rapid regional disaster recovery. However, in the present disaster response system, disaster relief is carried out at the level of public support, volunteer service, etc. There are various problems such as initial response due to lack of expertise, delays in disaster recovery, and inadequate response to disasters. Therefore, it is necessary to establish a unit with early ability to respond to local governments in the event of a disaster and expertise to enable rapid disaster recovery. Therefore, this study limited the preparation of the reserve forces emergency response units for the direction of local security, disaster relief and disaster relief through emergency disaster recovery under the disaster situation.

Recently, various public services are being performed based on information systems as the informatization business spreads. Public administration services based on these information systems provide internal and external services. In recent years, as the construction of cloud-based public services has been expanded, the advancement of information systems has attracted attention. In particular, as the dependence on information systems increases, the establishment of a response system to prevent dangerous situations such as interruption and paralysis of information systems in advance has become a hot topic not only in companies but also in public institutions. Therefore, in this paper, a disaster recovery system was designed and built to maximize the efficiency of system operation and shorten recovery time through service conversion automation of the disaster recovery system. The integrated DR server redundancy test, web server redundancy test, FC-IP redundancy test, and SAN switch redundancy test were performed respectively by applying the disaster recovery system designed and built according to the method proposed in the paper.

In this study, a study was presented on the monitoring technique of landslide area using UAV. In the case of disaster investigation using drone mapping, it can be used at various disaster sites. The mission can be carried out at various disaster sites, including surveys of damage to mountainous areas caused by landslides, building collapses surveys of flood damage, typhoons, earthquakes. The damage investigation plan using drone mapping is expected to be highly utilized at disaster sites where investigators cannot access it like in mountainous areas and where it is difficult to conduct direct damage investigations at the site. Drone mapping technology has many advantages in terms of disaster follow-up, such as recovery. Compared to the existing survey system, which was mainly carried out manually, the investigation time can be drastically reduced, and it can also respond to disaster sites that are difficult to carry out or are difficult to access directly. In addition, it is possible to establish and guide spatial data at the disaster site based on accurate mapping data from the time of the disaster, which has considerable strength in managing the situation of the disaster site, selecting priority areas for recovery, and establishing recovery plans. As such, drone mapping is a technology that can be used in a wide range of sites along with natural disasters and social disasters. If a damage investigation system is established through this, it is believed that it will contribute significantly to the rapid establishment of recovery plans along with the investigation of disaster response time and extent of damage recovery.

Currently, numerous companies and institutes provide services using the Internet, and establish and operate Information Systems to manage them efficiently and reliably. The Information System implies the possibility of losing the ability to provide normal services due to a disaster or disability. It is preparing for this by utilizing a disaster recovery system. However, existing disaster recovery systems cannot perform normal recovery if files for system recovery are corrupted. In this paper, we proposed a system that can verify the integrity of the system recovery file and proceed with recovery by utilizing hyper-ledger fabric blockchain. The PBFT consensus algorithm is used to generate the blocks and is performed by the leader node of the blockchain network. In the event of failure, verify the integrity of the recovery file by comparing the hash value of the recovery file with the hash value in the blockchain and proceed with recovery. For the evaluation of proposed techniques, a comparative analysis was conducted based on four items: existing system recovery techniques and data consistency, able to data retention, recovery file integrity, and using the proposed technique, the amount of traffic generated was analyzed to determine whether it was actually applicable.

We evaluated the problems of the current disaster psychological recovery support system of the Ministry of Interior and Safety for periodic infectious disease disasters, including COVID-19 (coronavirus disease 2019). The current disaster psychological recovery support systems are challenging to preemptively respond to infectious disease disasters over a wide range and for a long period. These result from the workforce shortage according to the face-to-face consultation method and the limited real-time application of consultation contents. Additionally, due to the workforce shortage, it is difficult to track those who have experienced disasters in the long term. Furthermore, most disaster psychology evaluation tools are for adults, and there are few evaluation tools for children and adolescents. This paper presents an advanced disaster psychological recovery support platform technology that can actively assist people in psychological recovery from disasters while mitigating these issues.
