This thesis grasped problems by examining the current status of disaster response system repeated during the disaster according to the changes of social environment and suggested current status of disaster response system and developmental measures through the investigation of the awareness of fire-fighting officer. On disaster site, close cooperation system of disaster safety measure headquarter and urgent rescue controlling association must be formed and range and time of the action must be accurately improved so as not to cause duplication of rights for orders. Also, systematic education and training system must be established so as to strengthen disaster site reaction capability and manpower and equipment for it must be increased. Finally, detailed measures for improving initial reaction capability during the disaster, such as tactic development, reaction plan establishment, etc, are requested.

The purpose of this study Is to recommand all kinds of library in Korea to develop a disaster plan. The materials in the library are apt to get damaged at once by such disasters as fire or flood etc. It is fortunate that we Have not found any big disaster at libraries in Korean. considering many cases of big disaster which distroy materials at library in foreign countries. In spite of the posibility of disaster any time, that will make librry loss of function, there are no library that have a disaster plan in Korea. Disaster plan is a guidance by which materials are conserved at ordinary times, protected and recoverd in contingency. It consists by four elements: prevention, preparedness, reaction and recovery. As libraries function by biblogrophic data and user data in automation system, it is also recommended to prepare system protection in the disaster plan.

Smoke composed of harmful gases such as carbon monocide and carbon dioxide is reconized as the major killer in fire situation. Especailly it is said that smoke movement is related to the panic phenomenon which threatens the life seriously. The purpose of this study is to investgate and analyse the reaction mechanism of harmful gas caused by fire effects on the human psychology and panic phenomenon.

We investigate the various factors such as earthquake, fire, flood and deterioration factors such as carbonation, salt attack, freezing thawing, alkali-aggregate reaction effects on the school facilities. As the consequence of this study we can see that there are very relative relation between deterioration factors and disaster factors. It is the aim of this study to investigate the site analysis damaged by disaster and deterioration factors of school facilities.

To decrease the damage of infrastructure from the natural disaster, initial reaction and emergent recovery are important. But up to now emergent recovery has mainly focused on the situation notices owing to the lack of technical support. In this paper, we described a web-based support system for disaster damage recovery of facility and electronic documents for requesting support of recovery resources. Recovery methods are decided using the damage recovery scenarios based on the acquired damage information, and the allocated recovery resources information is delivered to the recovery resources owner using the electronic documents. This system could readily be used for disaster response and emergency recovery.

This paper discusses the standards for disaster prevention and safety management of rail tunnel. The purpose is to establish safety management standards and methods of disaster prevention for each underground traffic spaces, after the full revision of the cause of accidents and its effects, the function and selection of safety equipment, and the efficiency and convenience of maintenance, standards based on prevention and reduction is proposed to reaction to disaster.

This study was performed to evaluate the effect of the addition of vegetable oils on Fenton treatment of PAHs-contaminated soil. Fenton reaction can be proceeded in the soils contaminated with PHAs only in the presence of $H_2O_2$ because of Fe content in the soil. In this case, optimum $H_2O_2$ concentration was 3%. When 17.5 mM $FeSO_4$(III) was added with 3% $H_2O_2$, the removal rate was increased up to 25%, whereas 19% of PAHs was removed with $H_2O_2$ alone. The addition of 1% of olive oil to the contaminated soil before the Fenton reaction or simultaneously increased the removal rate about 15%, compared to the case of Fenton reaction only. There were no significant differences in the removal rates of PAHs, regardless of different kinds and concentration of oils. (olive oil, soybean oil, and used-vegetable oil). The used-vegetable oils were not different from the new, expensive oils in the removal rate, so their use will be desirable in saving the money. In addition of 1% of olive oil after the reaction of 3% $H_2O_2$ and 2.5 mM $FeSO_4$(III), the removal rates of 3~4 and 5~6 ring compounds were increased 13% and 17%, respectively, compared to the case of Fenton reaction only.

Warning phase of disaster is a critical period in determining the likely survival of threatened citizens. Elderly requires special attention primarily because they tend to be uncompliant and less likely to cooperate with authorities. But there is much less research on how elderly respond to disaster warnings, while there is a strong consistent empirical literature on older citizen in the recovery periods of disaster. The purpose of this study is to examine coping behavior of elderly when they are at risk of disaster. Data were collected from 130 senior citizens aged over 60 who are residing in Pyungchang and Injae in Kangwon province which had damaged due to heavy rain in 2006. Perry & Lindell(1997)'s index, a series of six categories that represent coping behaviors which progressively approximate the action of evacuating was used : do nothing(1), check environmental cues for evidence of a threat(2), engage in threat-specific property protection(3), engage in protective action for personal safety(4), prepare to evacuate(5), evacuate the areas as instructed in the warning(6). Almost respondents(69.2%) chose the level 6(51.5%) and level 5(17.7%). This proves the elderly are not uncompliant or uncooperative population. Furthermore, this finding emphasizes the importance of public warning in case of disasters. And 13.8% of total respondent checked level 1 for their reaction.

In this study, it is compared various coefficients of subgrade reaction for application of numerical analysis based on measured data by using various theories and empirical formula. The ratio of the maximum and minimum value is 6.80 at the top of wall but it is 1.06 at the maximum displacement point depends on change of calculated coefficient of subgrade reaction. The data of displacement were generally similar considering an increment of a coefficient of subgrade reaction. And the results of comparison of the displacement at the maximum displacement point by numerical analysis and measured data show similar displacement shape.

This study developed a scenario to understand the reaction rate and operational time according to RTI value of rate of rise detector in each type in case of fire mattress. In the results of analyzing the reaction rate and operational time of detector in each scenario, in case when installing a single detector, the elevated temperature per minute was raised to 8℃/min ~ 9℃/min. In case when installing two detectors, it was raised to 9℃/min ~ 10℃/min. In case when installing three detectors, it was raised to 10℃/min. The horizontal distance between detector and mattress was 1.8m~2.5m. Whenever the number of detectors was increased, the horizontal distance was decreased. The operational time of detector was within maximum 540 seconds and minimum 420 seconds. As the research tasks in the future, there should be the researches on the effects of reaction rate of detector on the evacuation in case of fire through the result value of RSET by setting up the latency until the detector operates, and the researches on the safety by understanding if the operational time of detector is suitable for the evaluation standard of performance-centered design.
