Media Reporting of Natural Disaster: the Case of Typhoon Rusa
Kim, Man-Jae ;
Journal of Korean Society of Hazard Mitigation, volume 5, issue 3, 2005, Pages 1~9
The primary source of disaster information for victims as well as ordinary people is mass media. In spite of their importance, the media often inaccurately portrays reality, which has stimulated academic debates. In Korea, however, media reporting patters of disaster have been hardly addressed. Therefore, the paper analyzes how newspaper and television news have reported typhoon Rusa between August 29 and October 1 in 2002 by using KINDS(Korean Integrated News Database System). The results show that television news tend to present more soft news stories emphasizing human interest stories than newspaper articles, relying on victims as primary interviewees. It is also pointed out that the Korean media do not play a significant role in providing disaster information to public regarding how to lessen the effects of impact through preparation. Disaster mythology representing wrong beliefs about human behavior in disaster is found in Korean media reporting, too. Unlike their western counterparts, however, Korean media seem to use the dependency image of helpless victims in order to stimulate donations. Analyses of disaster reporting patterns suggest that, in make disaster warning messages associated with behavioral responses, credible and official sources should provide clear and precise warning messages to the media, and the media also need to stress individual responsibilities in protecting his or her own properties not to make victims heavily dependent on public supports, while inducing donations.

Journal of Korean Society of Hazard Mitigation, volume 5, issue 3, 2005, Pages 11~21
This study is performed to understand complex behavior and to investigate the rational analysis methods for seismic design of the curved bridges. To analyze the curved bridges for the seismic loadings, it is used that the finite element analysis program has the 7-dof curved beam and straight beam element. The free vibration characteristics of the curved bridges are compared with the straight bridges that have span length same as the average arc length of inside and outside girder of those. For the same case, the dynamic behavior is compared under seismic loadings. It is found that regular bridges classified by AASHTO are analyzed as if those were straight. To investigate the dynamic behavior of general curved bridges under seismic loading, the seismic loading directions and the subtended angle of curved bridges are varied.
A Study on the Automatic Pressure Differential Sensor Development of Smoke Control Zone
Lee, Dong-Myung ;
Journal of Korean Society of Hazard Mitigation, volume 5, issue 3, 2005, Pages 23~28
This study defined engineering mechanism and compensation method to establish reference pressure of smoke control zone with atmospheric pressure that is compensated for temperature. The reliable pressure differential sensor was developed by establishing the specifications, algorithms and constructing engineering data. The development of pressure differential sensor can cut down number of processes, manufacturing and installation cost by removing pressure measurement pipe established separately for non smoke control zone, and improve the accuracy of pressure differential by embedding pressure measurement ports for non smoke control zone. More correct and reliable pressure differentials can be obtained by the central control rather than the existent individual control. This will provide the basics and the flexibility to the integral smoke control system and accordingly improve the performance of disaster prevention.

Journal of Korean Society of Hazard Mitigation, volume 5, issue 3, 2005, Pages 29~39
The objective of this study is to analyze the relation of critical duration according to hydrologic characteristics in urban areas. RRL, ILLUDAS, SWMM, and SMADA urban runoff models were applied to the Seongnae and Banpo watershed and experiment area of the Dong-Eui University. Also, hydrologic characteristics such as temporal pattern of rainfall, rainfall intensity formula, antecedent moisture condition, return period, and urban runoff model were used to simulate the critical duration of the test areas. The results of this study are as follows; (1) The type of temporal pattern of rainfall which causes maximum peak discharge in urban area has resulted in Huff's 4th quartile distribution. (2) The critical duration in urban areas were not influenced by hydrological factors except urban runoff model. (3) Peak discharge and critical duration in urban areas were influenced by the urban runoff model, and the SWMM model using Huff's 4th quartile distribution shows maximum critical duration.

Lee, Joon-Ho ; Yoon, Sei-Eui ;
Journal of Korean Society of Hazard Mitigation, volume 5, issue 3, 2005, Pages 47~55
In order to design and manage the urban streams, the change of hydraulic characteristics by vegetation must be analyzed clearly. Planting criteria of vegetation in a urban stream were investigated and the design method of vegetation permission map was analyzed in this study. In addition, variations of water level due to vegetation are calculated by quasi two dimensional numerical model, HEC-RAS model and FESWMS model. Joongrang stream(Gunja bridge
Jangan bridge reach) was selected as the case study stream. According to the criteria of vegetation, it is decided that vegetation density was
tree/ha for selected tall tree in right floodplain and shrubs can be planted in the right and left floodplain area except the important hydraulic structures site. The selected shrubs planting simulations with three models show that water level in selected floodplain area increase approximately 12cm for the 100 year return period flood. The applicability of vegetation permission map in Korean urban stream was analyzed in this paper.

When arch ribs are subjected unsymmetrical load, buckling strength Is lower than strength of arch ribs subjected symmetrical load. However, A few study about the buckling strength of arch ribs subjected unsymmetrical load is performed compare with study about arch ribs subjected symmetrical load. Several researchers(Deutch : 1940, Chang : 1973, Harrison : 1982) studied about arch ribs subjected unsymmetrical load and they found that unsymmetrical loading reduces the critical buckling load. But, their results are limited parabolic arch ribs. This paper focuses on circular arch ribs subjected to unsymmetrical loading. The result shows that the ratio of live and dead load length to cause smallest critical buckling load of arch ribs is
under geometric nonlinear condition and
under both material and geometrical nonlinear conditions.

Hur, Man-Sung ;
Journal of Korean Society of Hazard Mitigation, volume 5, issue 3, 2005, Pages 67~72
This study is intended to examine the effect of photoluminescent exit path markings in the event of failure of both the power and back-up power to the lighting and illuminated exit sign. To achieve the purpose, the test house was exhibited in Fire EXPO '05. 520 visitors were examined from May 26-29, 2005. The results of this study are as follows; The evacuation from buildings in dark conditions showed that 70% of men and 72% of women were crawled along the wall. Meanwhile, 88% of men and 83% of women were evacuated with ordinary walking in photoluminescent exit path markings. The photoluminescent exit path markings located on public buildings floors will aid in evacuation from buildings in the event of failure of the power to the lightings and illuminated exit signs.

A Study on the Actuality of School Safety and the Development of Safety Manual
Kim, Tae-Hwan ;
Journal of Korean Society of Hazard Mitigation, volume 5, issue 3, 2005, Pages 83~88
It is necessary to hold the school safety manual because recently, the safety-related accidents occur frequently in schools. Accidents can occur inside of schools as well as out of schools, and they can be classified with human accidents, traffic accidents, fire accidents, and explosion accidents. Safety-related accidents occurring in the school are dangerous because nobody can predict them. Illegally infringing violence, targeting unspecified and a lot of people, informs the parents and persons concerned to education of danger. School safety manual, never precedented before, describes epoch-making educational methods for students' safety. It describes safety security such as refuging ways at an emergency, the way to recognize danger for elevated safety based on prevention education, the use and practice of checklist for related facilities, and the implements and facilities for school personnels and students. So, the school safety manual is an important guidance for safety education at the level of prevention from various accidents which occur inside the school as well as out of the school. It presents a variety of prompt response after an accident. At the same time, it checks facilities and dangerous factors in schools and facilities for safety, and analyzes special factors based on them. So it will present the status of safety management of existing facilities and implements, the installment of new facilities and implements, and the way to secure safety for use.
