Wireless Video Sensor Networks (WVSNs) have become a leading solution in many important applications, such as disaster recovery. By using WVSNs in disaster scenarios, the main goal is achieving a successful immediate response including search, location, and rescue operations. The achievement of such an objective in the presence of obstacles and the risk of sensor damage being caused by disasters is a challenging task. In this paper, we propose a fault tolerance model of WVSN for efficient post-disaster management in order to assist rescue and preparedness operations. To get an overview of the monitored area, we used video sensors with a rotation capability that enables them to switch to the best direction for getting better multimedia coverage of the disaster area, while minimizing the effect of occlusions. By constructing different cover sets based on the field of view redundancy, we can provide a robust fault tolerance to the network. We demonstrate by simulating the benefits of our proposal in terms of reliability and high coverage.

Objectives : These days assaults and other natural and human disasters are increasing. But oriental medical treatment researches in Korea are limited in car accident PTSD patients only. Our object is to explore an oriental medical intervention model for the evidence-based approach to PTSD after diverse trauma including disasters. Methods : Domestic papers for Korean researches are obtained from oriental medical related journals by internet searching. International materials are obtained from PubMed searching and a publication from Department of Veterans' Affairs. After assorting searched articles into RCTs and non-RCTs, we analyzed the articles according to the elapsed time from trauma. Results : We confirmed that acupuncture, CBT, and PMR were effective in acute stage after traumatic event. And EMDR, EFT, and relaxation therapy were effective in chronic stage after traumatic event. Building on the findings, we proposed a model of oriental medicine for Disaster Mental Health. Conclusions : Analyzing previous researches about oriental medicine on PTSD, several interventions were confirmed the effectiveness on specific treatment stage. We could find the possibility of Oriental Medicine as a Disaster Mental Heath and proposed a model of Oriental medicine for Disaster Mental Health.

In the U.S., the state, local, tribe, and territorial governments seek funding from the federal government through the Public Assistance program to carry out these recovery works. In this paper historic public assistance data between 1998 and 2021 have been analyzed to derive several insights such as: types of disasters causing the most damage, states requiring more support, net present value of the federal expense etc. This paper has found that the states requiring more support from the federal government are not always the states suffering the maximum losses from the disasters. It has also found that the net present value of the federal expense between 1998 and 2020 to restore, repair, reconstruct, or replace disaster damaged roads and bridges across the U.S. is $15 billion in 2021 values. Moreover, this paper has tested the correlation between the states' public assistance funds requirements and the existing condition and performance of roads and bridges as revealed by the American Society of Civil Engineer's infrastructure grade card. It has found a weak correlation between these two. The outcomes of this paper can be used by the decision makers to analyze the viability of any possible alternative to the exiting public assistance program. The insights can also help in better decision making in pre-disaster preparation and post-disaster funds allocation.

Recently, various types of disasters have been occurring all over the world, and the importance of disaster management system to minimize damage caused by disasters is emerging. In Korea, we have made many policy improvements related to disaster safety, such as the establishment of the National Security Service and the announcement of the National Safety Management Plan and made a lot of effort to secure facilities such as disaster relief hospitals after the Mauna Ocean Resort Gymnasium Collapse and the Sewol-ho incident, However, compared to advanced countries such as the US, Europe, and Japan, there is a shortage of emergency medical center per population, and disaster management systems have not been implemented efficiently due to lack of coordination among various agencies. The purpose of this study is to propose the efficient construction and systematic management of emergency medical facilities required for disaster situations. For this purpose, it is necessary to identify the current status of domestic emergency medical facilities compared to developed countries.

Firefighters receive extreme stress and suffer from PTSD in disaster. But we have not been paid attention to them. The purpose of this study is to analyze the problems of previous PTSD education programs in fire academy and to present the practical educational programs for firefighters to use in the disaster field. In the empirical analysis of this practical educational programs(EFT program), this program is more effective than existing theory-focused education training program.

This paper introduces the applications of Taiwan Earthquake Loss Estimation System (TELES), which is developed by the National Center for Research on Earthquake Engineering (NCREE). Seismic disaster simulation technology (SDST) integrates geographical information system to assess the distribution of ground shaking intensity, ground failure probability, building damages, casualties, post-quake fires, debris, lifeline interruptions, economic losses, etc. given any set of seismic source parameters. The SDST may integrate with Taiwan Rapid Earthquake Information Release System (TREIRS) developed by Central Weather Bureau (CWB) to obtain valuable information soon after large earthquakes and to assist in decision-making processes to dispatch rescue and medical resources more efficiently. The SDST may also integrate with probabilistic seismic source model to evaluate various kinds of risk estimates, such as average annual loss, probable maximum loss in one event, and exceeding probability curves of various kinds of losses, to help proposing feasible countermeasures and risk management strategies.

A great number of moment-resisting steel structures collapsed due to ductile crack initiation at welded beam-column connections, followed by explosive brittle fracture in the Kobe (Hyogoken-Nanbu) earthquake in 1995. A series of experimental and numerical studies on cracking behaviors of beam-column connections in steel bridge piers were carried out by the authors' team. This paper aims to study the effect of post weld treatment on cracking behaviors of the connections during a strong earthquake event. Experiments of three specimens with different weld finishes, i.e., as-welded, R-finish, and burr grinding, were conducted. The experimental results indicate that the instants of ductile crack initiation are greatly delayed for the specimens with R-finish and burr grinding finishes compared with the as-welded one. The strain concentration effect in the connection is also greatly reduced in the specimens with post weld treatment compared with the as-welded one, which was also verified in the tests.

This study examines the process of internalization and elaboration of the logic of competition in the post-IMF era through the genealogy of the survival program. Post-IMF is based on disaster reality, which reveals a specific emotional structure related to the competition, if the narrative of overcoming the IMF event finds narrative models that can be sufficiently reconciled between communityism and individual success. This study also examines the process of disaster preparedness through survival form and narrative structure embedded in such form. Thus, this study reconstructed the diachronic change to track the change of the survival program and the subsequent narrative change. Relative to the time of the healing-mentor, the survival program seems to be declining, but rather seems to have created a new transition through the logic of self-development contained in the healing-mentoring discourse. this logic leads to be ghettoized hierarchy of preferences. Now, the survival program is to perform fantastic surrogate satisfaction by delegating competition to a narrow self-directed area rather than to a big empathy within the community.

Korean society became an 'aging society' in 2000 years with a population of 65 years and over occupying $7.2\%$ of the whole population. And we expect that a population of 65 years and over will occupy $14.4\%$ in 2019 years, so Korean society will enter into an 'aged society' Older adults can't react correctly and rapidly to the disaster due to the decline of the physical function, therefore victims of older adults due to the disaster will increase as much as aging proceeds. For reducing sacrifices of older adults due to the disaster, 1 suggest that the propulsion of the disaster service policy for disaster week people like older adults, the policy of minimizing casualties due to fires, reinforcement of fire resources and enlargement of disaster services in rural communities, offering information about disaster services and reinforcement of functions of public relations, making new connection systems (e.g. educating welfare and post officials as volunteer fire officials), supplement of fire fighters, and the policy of lightening fire equipments.
