An expert network administrator is not always stationed as disasters happen. In that case, it is desirable that a novice administrator is capable of taking part in network recovery operations as well. In this paper, an agent-based network management system in emergency situations is presented. We use the Active Information Resource based Network Management System (AIR-NMS) to relieve the human administrator from parts of her management tasks and present an interface that remotely can control this management system. The effectiveness of the system is demonstrated by experiments using a prototype system.

Device-to-Device communication is a very important essential feature in PPDR(Public Protection Disaster Relief) communication, but it has not yet been implemented in LTE-based PPDR communication. In this study, we propose a solution to implement the LTE-based domestic PPDR communication network by evolving the terminals into D2D in-band terminals and effectively operating the current PS-LTE terminals and digital radios in the transitional period.

Recently, due to the large-scale damage of natural disasters caused by global climate change, a monitoring system applying remote sensing technology is being constructed in disaster areas. Among remote sensing platforms, the drone has been actively used in the private sector due to recent technological developments, and has been applied in the disaster areas owing to advantages such as timeliness and economical efficiency. This paper deals with the development of a preprocessing system that can map the drone image data in a near-real time manner as a basis for constructing the disaster monitoring system using the drones. For the research purpose, our system is based on the SURF algorithm which is one of the computer vision technologies. This system aims to performs the desired correction through the feature point matching technique between reference images and shot images. The study area is selected as the lower part of the Gahwa River and the Daecheong dam basin. The former area has many characteristic points for matching whereas the latter area has a relatively low number of difference, so it is possible to effectively test whether the system can be applied in various environments. The results show that the accuracy of the geometric correction is 0.6m and 1.7m respectively, in both areas, and the processing time is about 30 seconds per 1 scene. This indicates that the applicability of this study may be high in disaster areas requiring timeliness. However, in case of no reference image or low-level accuracy, the results entail the limit of the decreased calibration.

Wireless communication system for firefighters has an important role as the last communication method between the commander and the firefighters in disaster sites like fire. But the operation of Gyeongnam wireless communication system is installed, and maintained and controlled without criteria for the selection of a transmitting station and the analysis of propagation environment because of the lack of budget and the absence of professional personnel. To improve the performance of the radio station, this paper theoretically calculated free space loss of UHF 400 MHz band used by all firefighters in Gyeongnam and diffractions caused by single and multiple obstacles and computed the error after comparing the results of the actual measurement to those of simulation with FRAS operated by KFL. In the results, Deygout model was the most consistent with the actual measurement for 400MHz band in Kimhae site.

고령화사회에 접어들며 고령운전자의 교통사고 비율이 높아지고 있다. 현재 사회적 문제로 자리 잡은 고령운전자의 교통사고 문제는 고령화사회가 진행될수록 더 많은 문제를 야기하게 될 것이다. 본 논문은 고령화 사회로의 변화와 고령운전자의 특성과 대책에 대한 현황과 문제점을 알아보는데 그 목적이 있다. 이를 기반으로 안전 약자에 대한 사고 비율을 감소시킬 수 있는 교통신호등 디자인을 위한 지속적인 후속연구가 진행될 것이다.

According to the actual situation of a university, the emergency evacuation simulation is modeled based on the physical sign, evacuation speed and personnel ratio using the pathfinder software.The experimental construction export utilization rate is compared with the preliminary simulation scenario. The simulation results show that the utilization rate of evacuation stairs and evacuation exits is significantly improved.The optimized solution can provide the most effective evacuation passage, and the research results can provide the basis for the rational planning and management of evacuation passage in university experiment building.

This study has some issues about the elderly, the disabled, and the vulnerable groups whose economic ability is low even if the disaster or disaster situation is not a big problem for the people. we should emphasize the necessity of disaster preparedness action manual considering the characteristics of disaster vulnerable classes and taking serious risks to them even in the same situation. We also want to conduct research only for people with disabilities who are choosing the same definition of the world among the vulnerable groups. I would like to provide a basis for developing a site action manual for people with disabilities by comparing the cases of Korea and Japan. Therefore, through the cases of Japan and Korea, it is possible to maintain the independence of everyday life during disasters, the communication function in disasters, the method of moving information and mobile information, the function of recognizing emergency response, Action Emphasize the urgency of developing action manuals. From this domestic situation, we will conclude the discussion on the disaster safety and action manual for the disabled.

Disasters in South Korea are taking on more diverse and intricate aspects than before, while being affected by the industrial development and deterioration of the cities. Therefore, it is urgently needed for success in disaster countermeasures to secure emergency communications operating system which would make it possible to share various information between the control tower and field personnel quickly and accurately. This study proposes a method of improving the national emergency communications operating system based on the Federal disaster management system, emergency communications system, and Standard Operating Procedures (SOPs) employed in the US, which is the leading country in the field of disaster management. First, the organization of the emergency communications needs to be more systematized than in the past. The organization of the emergency communications of the central and local governments have to be administered according to their different roles and objectives. Furthermore, they must cooperate with each other based on interoperability. Second, emergency communications councils need to be established, composed of representatives related to disasters, and national and regional units need to be formed and operated separately. Third, the SOPs should not only cover both the operational and technical elements, but also assign the roles and responsibilities to the members of the disaster communications system. These improvements will assure the correct functioning of the disaster communications system in the field, which is expected to increase the probability of success in disaster countermeasures.
