Purpose: The purpose of this study was to investigate the disaster experience (accidents, education etc) and the concern for disaster preparedness of college students. Methods: This research design was a descriptive study. Data were collected from November 1, 2011 to December 30, 2011 and analyzed by the SPSS PASW statistics 18.0 program. Results: There were statistical significances in major (p<.050), grade(p<.001), and a completed disaster class(p<.001) between general characteristics and concern for disaster preparedness. The major disaster events that occurred from 2003 to 2010 in Korea were the 2007 Taean oil spill (85.4%), the 2003 Daegu subway fire (82.7%), and the 2008 Sungnyemun fire (62.9%). The possible disaster events in Korea were hurricanes, floods, fires (including wildfire), and the shutdown of communication lines. Subjects learned about cardiopulmonary resuscitation (18.2%), first aid for bleeding and fractures (17.8%), a fire drill (14.3%), and an escape drill for an earthquake (14.0%). They wanted to learn the fire drill (11.33%), the escape drill for an earthquake (9.7%), a war drill (9.0%), a disaster confrontation drill on the subway (8.6%), and a fire and explosion evacuation drill (8.4%). Half of subjects were not prepared with emergency supplies for disasters because they thought that a disaster would not occur. Conclusion: It is necessary to develop the disaster educational programs according to subject's demands in Korea.

The trend of constructing skyscraper has arisen to the offistel and apartment complex due to the lack of exploitable land and urbanization. But, the phenomenon of the multi-story buildings is different from the regular building because of the possibility of mass disaster in fire. Therefore, Analyzing and comparing our actual condition and Japanese, It is going to be suggested that the introduction of fire escape ladder for residents in emergency.

As the rapid and various changing of social aspects, the structures are getting bigger, higher and more complex. The importance of evacuation is on the rise as increased using frequency of multiplex area and it's high population density. According to the result of a survey with 2 domestic multiplex population density, the maximum was 0.43(人/$m^2$) and 0.51(人/$m^2$). considering evacuation dangerousness, the maximum value will be suitable for computation of evacuation capacity and this will be submitted as a basic data for computation of evacuation capacity.

Recently the consideration for occupant's security has been raised as very important design element from the fire by building's large sized, higher storied, and its compounded. But the domestic laws regulated the predicative laws according to the technical standard which has no difference from the past domestic evacuation regulation. Therefore, regulation of escape code and developing technology for Korean conditions are needed to reduce victims during disaster by protecting occupant and guiding people to safe places.

Many pressurization systems are designed and built with the goal of providing a smoke-free escape route in the event of a building fire. A secondary objective is to provide a smoke-free staging area for fire fighters. In the present study, a computer program is developed to calculate pressure loss and flow rate at several building elements such as a room, a ]tabby a staircase and an air supply shaft. By the program as the dosing tool for the pressurization system, the capacity of the injection fan is calculated, and the design method is proposed for the optimization of the fan capacity.

In case of tunnel fire, one of the most effective facilities to save lives is the smoke control system. In this study, two different smoke extraction schemes of transversely ventilated tunnel were compared. One is the smoke extraction using the fixed exhaust ports on the false ceiling to achieve the uniform and distributed smoke extraction (uniform exhaust). The other is that using the remote controlled smoke extraction where only vents close to the fire is opened whereas the others are closed to enhance the limitation of the smoke spread (localized exhaust). A number of numerical simulations were performed to find out the optimal smoke extraction rate at each smoke extraction scheme to allow the tunnel users to escape to the safe area without endangering their lives by smoke.

Though the probability of tunnel fire accident is very low, but critical fatalities are expected when it occurred. In this study the effect of critical safety parameters on tunnel fire accident are examined using probabilistic technique. Fire detection time, smoke spread velocity, passenger escape velocity, flash-over time, and emergency service arrival time are considered. In order to estimate the uncertainties of input parameters Monte Carlo simulation are used, and fatalities for each assumed accident scenarios are obtained as results. For the efficiency of iterative calculation PRA(Probabilistic Risk Analysis) code is developed in this study. As a result fire detection have large effect.

The purpose of this study is to present the possibility of adopting beacons to implement the fire evacuation guidance system in order to reduce the evacuation time for a fire in complex buildings. A beacon-based evacuation system can quickly detect a fire's origin, optimal path of evacuation involved with the exits and the location of evacuees using information collected by the proposed system. The assessment is conducted by integrating different scenario models including fire simulation. Based on the research result, beacon is an effective tool to warn potential hazards or to provide early detection and a safe escape.

Fire characteristics of a typical apartment building in Korea was studied through full scale experiment and zone model simulation. The fire was ignited at the living room and allowed to spread to other parts of a single unit in a five storied apartment building. Various data including temperatures, species concentrations, and images were collected in the experiment. A zone model(CFAST) was used to analyze the same apartment building that represents the average households in Korea. The results were compared with a full scale experiments. While CFAST allows one compartment involved with fire, the experiment allowed the fire to spread to other compartments. Therefore, the comparison between experimental data and Zone-Model data is valid until the living-room fire spread to other parts of the apartment. Flashover occurred at approximately 380 seconds in a fire experiment, and at approximately 420 seconds in Zone-Model. Based on all of data between experimental data and Zone-Model data, it is concluded that the safe escape time is about 250 seconds.
