  • The principal basic concepts of aseismic design minimize damage of human-life and have little probability during life of structures. For detailed understanding of the design, the best reasonable countermeasure can be possible equally the smallest damage of human-life and economic loss. As a result, it can be achieved by notion of not structure-centered but city-centered, the notion is actualized by development of a macro-level evaluation. A seismic damage between city and country is different. And the larger the city then, the greater the loss by rather collateral hazards than collapse of structures. Hence, the macro-evaluation of an earthquake disaster is suitable for an old city where is center of political and economic activity, and is concentration of population and infrastructure. This study aims to develop comprehensive earthquake desaster risk index, and assesses relative earthquake risk of six zones in Seoul metropolitan area.

  • A steel shear wall with double-tapered links and in-plane reference was developed for assisting the assessment of the structural condition of a building after an earthquake while maintaining the original role of the wall as a passive damper device. The double-tapered link subjected to in-plane shear deformation is designed to deform torsionally after the onset of local buckling and works as an indicator of the maximum shear deformation sustained by the shear wall during an earthquake. This paper first examines the effectiveness of double-tapered links in the assessment of the structural condition under various types of loading. A design procedure using a baseline incremental two-cycle loading protocol is verified numerically and experimentally. Meanwhile, in-plane reference links are introduced to double-tapered links and greatly enhance objectivity in the inspection of notable torsional deformation with the naked eye. Finally, a double-layer system, which consists of a layer with double-tapered links and a layer with rectangular links made of low-yield-point steel, is tested to demonstrate the feasibility of realizing both structural condition assessment and enhanced energy dissipation.

  • A series of heavy rainfall, typhoon and earthquake disasters caused a proportionately large number of deaths among the elderly in the year 2004 in Japan. In response to these tragedies, the national government set up committees to reduce damage within the disaster vulnerable population for the next three years. The discussions in the committee led to a new conceptualization that disaster vulnerability was caused by a lack of interaction between a person's special needs and the environment's capacity and resources to meet them. This person-in-environment model of hazard vulnerability was applied to those who resided in the Nankai-Tonankai tsunami hazard-prone area. 123 home care service users were interviewed in terms of their self-evacuation ability, degree of social isolation, and building weakness as well as tsunami exposure risks. Results were quantified and scores of person-in-environmentmodel hazard vulnerability were obtained. These scores were then used to visualize socially created vulnerability by means of weighted kernel density mapping of both persons with special needs (PSN's) and persons with special needs at times of disaster (PSND's).

  • Purpose: This study identifies the impact on composition of the firefighting organization, fire command ability, and public opinion operation on organizational citizenship behavior for fire officials to respond to the earthquake disaster, and provides practical implications as basic data for firefighting organizations to cope with the earthquake disaster. Method: Questionnaire survey was performed for 159 fire officials, and the surveyed data was statistically analyzed by using SPSS 22.0 program. Result: First, the results of the verification of the hypothesis showed that the composition of the fire organization, firefield command ability and public opinion operation have a positive impact on organizational citizenship behavior. Second, the relative contribution of independent variables to the dependent variables was identified in the order of composition of fire organization, fire command ability and public opinion operation. Conclusion: The implications of this study suggested from a practical perspective that the government needs to organize firefighting organizations, develop firefield command ability and operate public opinion in advance in order to respond to earthquakes.

  • The purpose of this paper is to analyze the linkage between Si-Jeong-Chon (municipalities of Japan) catastrophic disaster recovery-regeneration plan (DRRP) and regional comprehensive plan (RCP), each of which was made after the Great East Japan Earthquake, and to make implications on establishment of a disaster recovery plan of Korea. In order to explore the relationship between the two plans, the DRRPs and RCPs of 30 municipalities are collected and categorized according to their characteristics. The results show that DRRPs of the municipalities are not always in a consistent form and contents because regulations and guidelines on DRRP are not definite and specific. The relationship between DRRP and RCP in terms of its form and contents can be divided into 3 categories; Reflective Type (RT), Complementary Type (CT), and Substitutive Type (ST). The 22 RT plans as the majority of those DRRPs appear to reflect the development strategies of municipalities' RCPs. Both 3 CT plans and 5 ST plans seem to be integrated with RCPs in some way. The plan in CT of a municipality supplements its RCP by adding some new strategies to its recovery section and the plan in ST of a municipality appears to replace its RCP. Finally the influential factors which are considered to determine linkage type are identified as remaining time which is legally required to re-establish its RCP, the extent of damage, and socioeconomic condition changes.

  • Objective : In October 2016, the most powerful earthquake, magnitude 5.1 and 5.8 struck the city of Gyeongju in Korea. Although it did not take a toll, this implicates potential disaster in the future. Taking this earthquake, this paper considers the healthcare system responding to disaster in non-government organization and other countries, and investigates the roles of occupational therapist in disaster management. Methods : This paper reviews literature related to healthcare system and roles of occupational therapist in disaster response. Results : Humanitarian recovery mission of Red Cross impacted and facilitated the recovery of vulnerable population including children, elderly and people with disabilities in disaster response. It was also emphasized by occurring large population with disabilities after disasters so that the concept of rehabilitation and occupational therapist's role was required. Occupational therapy practitioners play an important role in the stage of disaster preparedness, response and recovery and their target population is children, elderly and people with disabilities. Conclusion : The most of NGO and counties take the concept of rehabilitation into healthcare system responding to disaster. However, the system in Korea stays in emergency level. It is important to take the humanitarian recovery and rehabilitation concept to disaster relief. the survivors would be able to return to their normalcy and health life.
