Modern disasters prevent accidents in advance and recover after accidents are very important. Our government's current response to these accidents is not appropriate. As for disaster management so far, it has been the center of disaster response and recovery efforts, and has been led by the government against it. The reality is that most private organizations and agencies have only subsidized government disaster management agencies. Korea is no longer a safe zone for earthquakes. Now for the establishment of effective disaster management system for earthquakes in the diagnosis is very urgent and the problems of the operational disaster management, which the problems of the nation.Policies to improve academic efforts to seek alternative proposal is also at a time when volume can be said to be very big need to mine. This study from 2016 to 2019, about the earthquake that took place between National Statistical Office, based on analysis of data to. First of all, research 1: What was the government's plan on Pohang earthquake? The results showed that the residents' evacuation of Pohang was important in the Pohang earthquake, but for the sake of students' safety, they were directly assigned to the test site to cope with the emergency situation. Therefore, the research and analysis shows that the nation should continue to think about the causes and responses of the damage at the disaster site and strive to develop technologies and methods to minimize the damage.

The purpose of this study is to improve the repair and reinforcement of cultural construction assets made of wood and develop seismic countermeasures. The existing regulations for the earthquake proofing of cultural assets are termed 'Regulations concerning earthquake disasters affecting cultural assets' of the cultural heritage administration, which only specifies the reporting of damage to cultural assets after the occurrence of an earthquake. Since 2013, Korea has been studying the introduction of a seismic evaluation system consisting of experts by referring to the 'Guideline for the diagnosis and reinforcement of important cultural properties in Japan. The earthquake proofing of wooden cultural assets in Japan is assessed by experts using a scoring system similar to the one in Korea, but the system in Japan is managed in three steps, viz. before, during and after the occurrence of the earthquake. In order to extend the existing management system by focusing on the repair of the damage after the occurrence of an earthquake, it is necessary for Korea to cultivate experts for the regular management of cultural assets, establish seismic criteria for them, and introduce a regular management system through a civil organization related to construction. By examining the current status of wooden cultural assets, it is necessary to develop various seismic diagnosis techniques and produce guidelines for the repair and reinforcement of individual wooden cultural construction assets following their identification.

The first successful sustained powered flight by Wright Brothers was further extended to the rapid development of aviation technology, that led to transpacific flights, the invention of supersonic planes, and enabled hundreds of people to travel in the space, in addition to the fact that around 10 people had stepped on the moon, all of which were made possible within the very same century. However, on the back side of this most wondrous human technology, the vulnerableness to the aviation accident has been constantly accompanied with, right from the very beginning stage of the aircraft development. Moreover, the development of future aircraft is being focused on the aircraft performance, the increment of the number of passengers aboard and also its speed. In proportion to these phenomena of mega sizing the aircraft, the development of new technology and the increment of air traffic volume, the number of aviation accident is expected to augment, resulting in the enormous loss of human lives and properties. In order to prevent the disastrous aviation accident as such, it is essential to conduct the accident investigation in a specialized, systematic and scientific manner. In search for the method to attain the effective function of the aviation accident investigation organization, in this study, issues were examined as follows: The full-time Board Members and the establishment of an integrated investigation agency, The systematized security of status as an accident investigator, Inclusion of a human factors specialist in the investigator group organization, liability limit of an accident investigator Stipulation of the definition and the investigation scope of an accident and serious incident, along with the main body of conducting the investigation into the accident involving both civil and public aircraft, in the regulations related to the accident investigation.

An apartment house, a private facility, is a house built for many persons to live independently in a building. An apartment house is a building where life damage can happen most in case of a safety accident due to insufficient inspections. However, formal inspections are being realized due to awareness shortage of managing bodies about safety inspection and low-price order-receiving of diagnosing enterprises via the lowest bidding method. This is because it is judged that remarkable costs are inputted in repairs and reinforcement such as maintenance of a structure and that there is a large possibility of human damage in case of a safety accident in a structure. So, this paper aims to derive the points to improve in the current criterion to execute an efficient detailed inspection. As its method, the design price and execution price situation of 66 buildings inspected in detail for recent 3 years for the class 2 facilities in Gwangju Metropolitan City and Jeonranam-do are examined and analyzed. The state2 object buildings to inspect are selected through this. And this paper aims to present the points to improve through the analysis of current problems by evaluating the detailed inspection report and the detailed inspection execution price calculation criterion for the selected 10 apartment houses.

Energy industry facilities can cause fatal damage for internal industry employee as well as external general people because handling various kinds of gas and harmful substance might be spread to large scale severe accident by fire, explosion, and toxic gas leakage. In order to prevent these accidents, quantification by damage effect on structure and human is tried by using quantitative risk assessment, but it is difficult to process instantly exceptional cases and requires knowledge of expert. This paper aims to minimize exceptional cases and knowledge of expert, and present risk with human perceptible. So, we designed and developed zone-base risk analysis system that can compute risk of zone in real time at that point using database and incremental model.

In seasonal frozen areas which have a temperature difference in the winter and spring season like south korea, if stiffness reduction by repeated freezing and thawing occurs to slopes adjacent to private facilities or mountain slopes, safety factor is insufficient to design criteria and landslide could be occurs due to rainfall or snowfall. It can lead to large damage of human life and property. In this study, in order to examine the safety changes of mountain slopes by repeated freezing and thawing, soil samples series of SP and SM by USCS distributed in surface soil of mountain slopes were collected for specimens. Through the direct shear test, the characterestics of frozen soil shear strength were analyzed and by utilizing numerical methods, chracteristics of strength reduction of weathered granite soil according to repeated action of freezing and thawing, changes in the stability of the slopes when applying freezing and thawing of the soil samples were examined. As a result, the maximum shear stress decreased approximately 10%, and slope stability analysis confirmed that required safety factor is less than compare with the non-frozen samples.

How will South Korea design well-organized, open, and integrated counterterrorism system? Does this system work well in the emergent situation? These are very significant issues. It is likely that this system would give the solution. A legal basis needs to be established to have a well-organized, open, and integrated counterterrorism system. The core part of a well-organized, open, and integrated counterterrorism system is to minimize and eliminate damage caused by terror through preventiveness, preparation, action, and restoration. For having this system, they need to be divided into two section: an open one and an integration one. In this study, there will be a discussion on a new and appropriate counterterrorism system fit in South Korea a subordinate system: legal, organized, civil aspects need to be provided on the basis of an well-organized, open, and integrated counterterrorism system and an analysis on the current system of the States, England and the following implications.

Many defensive mechanisms have been evolved as new attack methods are developed. However, APT attacks using e-mail are still hard to detect and prevent. Recently, many organizations in the government sector or private sector have been hacked by malicious e-mail based APT attacks. In this paper, first, we built hacking e-mail database based on the real e-mail data which were used in attacks on the Korean government organizations in recent years. Then, we extracted features from the hacking e-mails for profiling them. We design a case vector that can describe the specific characteristics of hacking e-mails well. Finally, based on case based reasoning, we made an algorithm for retrieving the most similar case from the hacking e-mail database when a new hacking e-mail is found. As a result, hacking e-mails have common characteristics in several features such as geo-location information, and these features can be used for classifying benign e-mails and malicious e-mails. Furthermore, this proposed case based reasoning algorithm can be useful for making a decision to analyze suspicious e-mails.

The present study purposed to establish a network for building an efficient disaster response system and for this purpose, we compared cases of disaster response in Japan and Korea. In Japan, disasters are responded jointly through the network of the central government, local self governing bodies and non governmental organizations. In Korea, however, the cooperative network among different areas is weak and this is aggravating damages caused by disasters. That is, in Korea, disaster response services have been mainly carried out by the public sector. The public sector can operate a powerful disaster management system using its extensive management resources, compelling power, and legal authorities. However, it was found that, due to the characteristics of contemporary society, efforts by the public sector including the central government and the local self government bodies have limitations in managing disasters effectively. Thus, for efficient disaster response in Korea, it is urgently required to establish a national disaster response network as well as a private sector cooperation system and to induce NGOs to participate in the disaster response system through institutional devices.
