This is a study on the type of perception about the transition of female firefighters to emergency car drivers. The purpose of this study is to identify the perception of the female firefighters on the circulation of emergency car drivers and to identify the characteristics of each type of firefighting officers and to provide basic data for the development and utilization of the emergency car drivers' work of female firefighters. The Q-sample of 27 statements was conducted on 31 subjects including 26 women and 5 men, and the data were analyzed using the QUANL program. As a result, the three types classified explained 60.8 % of the total variance, and the explanation power of each type was 50 % for type I, 5.6 % for type II, and 5.2% for type III. Type I was named 'feminist type', type II was named 'future-oriented type', and type III was named 'educational preparation type'. According to the perception of emergency cars by female firefighters, it was investigated that discrimination caused by gender should be eliminated and female firefighters can drive an emergency car if preparation and systematic education are made. Therefore, fire officials need to develop their personal abilities through gender equality and systematic education programs.

The typical evacuation guidance system based on fire detectors, which is being widely used in theaters and large buildings, is often operated in an analog manner. In case of fire, it often causes the system to lose a wired line or wireless fire detection sensor, resulting in the difficulty of transmitting signals from a wired or wireless fire detection sensor to the main fire monitoring device. Accordingly, this paper has proposed the broadcasting system for disaster management, having an efficient evacuation guidance plan when a disaster occurs. The system reacts to an emergency situation along with fire alarm sirens in real time. We have implemented the above system by means of a simulation program that prints the evacuation guidance information (e.g., location and time of fire, and evacuation path) on an LCD located in a building through the fire sensor network in case of an emergency (e.g., actual fire). We have developed the simulation system by using mathematical algorithms, such as the optimal path search and the fire smoke diffusion algorithm. This simulation program considers the structure of a building and the location where the fire has initially occurred, applying it to the simulator.

The usual reasons for elderly safety accidents include lack of care for disaster, physical disability, and an error of judgment and so on. But it is true that accidents will occur continuously with the afore-mentioned causes. Against the elderly safety accidents, safety is the main prerequisite for leading the successful and easy life in the elderly. Therefore, this study is purposed to provide the way of thinking about elderly safety issues by suggesting the methods and contents of education program. This study is specifically focused on developing audio-visual materials involved in all the safety accidents and researching the effect of safety education ability through materials with a view to identify the substantial problems. Education program should make a continuous and long term study so that the curricula of the safety accidents prevention education can be done systematically.

Today, Korean Disaster Control System has better change the existed it for substantial prevention and the emergency control system. And it requires the new National Wide Disaster Control System through building up the cooperation system with related posts which are scattered over the National Administration and one-way management for disaster affairs by them. Therefore 119 that might have a lot of technical knowhow should be a center of disaster affairs which will be able to take all rescue, relief(first aid), fire fighting, and preventive affairs. Then it could be a service organization of citizen. Consequently, it will strengthen National Disaster Control ability and it could be a National Wide Disaster Organization which is ready for prevention, preparation, confrontation of all kinds of disasters with absolute reliance by the citizen.

The longest tunnel has been halted at Daekwanryung by the failure of the host country of the Winter Olympiad in 2014, but modern High-Power TBM will come to Korea to excavate these long tunnels to establish the better horizontal connection between the western and eastern countries to improve the strong powerful logistic strategy of Korean peninsula. Train operation provides a key function of air movements in a long underground tunnel, and heat generation from transit vehicles may account of the most heat release to the ventilation and emergency systems. This paper indicates the optimal fire suppress services and safety provision for the long railway tunnel which is designed twin tunnel with length 22km in Gangwon province of Korea. The design of the fire-fighting systems and emergency were prepared by the operation of the famous long-railway tunnels as well as the severe lessons from the real fires in domestic and overseas experiences. Designers should concentrate the optimal solution for passenger's safety at the emergency state when tunnel fires, train crush accidents, derailment, and etc. The optimal fire-extinguishing facilities for long railway tunnels are presented for better safety of the comfortable operation in this hard rock tunnel of eastern mountains side of Korea. Since year 1900, hard rock tunnel construction has been launched for railway tunnels in Korea, tunnels have been built for various purposes not only for infrastructure tunnels including roadway, railway, subway, and but also for water and power supply, for deposit food, waste, and oils etc. Most favorable railway tunnel system was discussed in details; twin tunnels, distance of cross passage, ventilation systems, for the comfortable train operations in the future.

This study analyzed local imbalances in the supply and demand of emergency medical services in Busan using the 119 emergency activity reports of the Busan Fire & Disaster Headquarters. The data for EMS activity reports in 2017 was converted into Jimgyegu units. The spatial distribution of the indicators representing the local imbalance of emergency demand and supply (number of reports, number of reports relative to the population, average coefficient of variation and outlier of on-site arrival time, and number of dispatches outside the jurisdiction) was analyzed using Hotspot analysis of GIS spatial statistics analysis. As a result of the analysis, the hot spot area and the cold spot area where both supply and demand of emergency services are concentrated were clearly distinguished. This means that the supply and demand of emergency services in Busan are locally unbalanced. In particular, there was a difference in the demand and supply of emergency services in the original downtown and its surrounding areas, and in the outskirts of Busan.

In this study, we considered the ignition possibility for the shredded thermoplastic elastomer at the fire ground loaded the waste TPE. The average moisture content of the TPE sample was almost 0.33 wt.% at $110^{\circ}C$ and the range of ignition point was $461.9{\sim}491.9^{\circ}C$ approximately. In addition, we analyzed the change of weight and calorie the TPE sample according to temperature variations using the TG-DTA analyzer. As a result, the weight loss occurred twice in $250{\sim}420^{\circ}C$ and $420{\sim}473^{\circ}C$, and we found the second weight loss temperature range was the ignition point of TPE. Also, we conducted the spontaneous ignition tests of TPE for the wet and dry samples and we confirmed that the possibility of spontaneous ignition of TPE was very low. The elapsed time and humidity had little influence on the spontaneous ignition of TPE in this experimental conditions. In conclusion, the spontaneous of the shredded waste TPE in this study.
