  • Securing fire safety using only fire-fighting facilities is difficult because causes of modern fire vary, such as architectural structures and building use patterns. In order for fire safety to be guaranteed by enacting and revising fire regulations reflecting the fire hazard characteristics and user's characteristics, the introduction of fire influence evaluation (fire risk assessment) system needs to be considered in a timely manner to be adopted but unfortunately two attempts before have failed. In this study, a fire case of urban lifestyle housing was surveyed to introduce a fire influence evaluation system and a field survey on the actual condition of the 414 urban lifestyle housing buildings and fire & evacuation simulation results of one representative building in Suyoung-gu and Nam-gu District of Busan Metropolitan City were analyzed. The necessity, procedures and implementation method of fire influence evaluation system were questioned and tested by the professional fire experts, fire officers and firefighters and architects. On the basis of these facts, introduction of (fire influence evaluation system) should be absolutely adopted and the fire department and fire regulation are eligible to implement the system. Therefore, fire regulation needs to be enacted or revised in accordance with the new fire environment and fire safety system that needs to be built up. Accordingly, aggressive promotion through public hearings on the necessity of fire impact assessments, consensus among departments and fostering experts to carry out fire influence evaluation system will be the core.

  • Enemy information has significant value when it comes to the process of military actions in battle field. Our Army now uses Battlefield Management Systems(BMSs) equipped in Ground Fighting Vehicles(GFVs) and we need to make research on what kind of role enemy information can play in such systems. Also, enemy information can be shared among GFVs and target information shall be extracted from it in view of KVMF scheme. Because KVMF becomes requisite standard in modern BMSs, we need to implement target information handling process in KVMF standard. In this article, we will focus on how target information and its sharing process can be managed efficiently without information conflicts. Also, situation map produced by it will be noted.

  • The purpose of this study is to propose an effective operating method of a power generator used by the Emergency Power System in case of a simultaneous fire and of the limitations of the interlock system the power supply from the emergency power generator. On the Emergency Power System with Reserved Fire-fighting Power (RFP), in case of an overload, the collective control Emergency Power System signals the main circuit breaker to shut off the supply to the emergency load, leaving the supply to the firefighting load uninterrupted to the end. The sequential control Emergency Power System signals the firefighting power supply to shut off the fire stage of the emergency load and continues to monitor the power supply. If an overload happens again from increased firefighting load, the sequential control Emergency Power System sends a secondary signal to shut down the second stage of the emergency load.

  • Fire fighters rely on fire fighter protective clothing (FFPC) to provide adequate protection in the various hazardous environments. To enhance its protection performance, the FFPC material must be thick and thus it is difficult to achieve weight reduction. One of the methods of overcoming this problem, the addition of phase change material (PCM) to FFPC, is a new technology. In previous studies, the researches was mostly related to the temperature characteristics of the fibers incorporating PCM, but little information is available about its effect on burn injuries. Thus, in this study, the inhibitory effects of adding PCM to FFPC on second degree burns were investigated through numerical calculations. Thermal analyses of biological tissues and FFPC with embedded PCM exposed to several fire conditions causing severe tissue damage were studied by using a finite difference method based on the Pennes bio-heat equation. FFPC with embedded PCM was found to provide significantly greater protection than conventional fire fighting clothing, because the heat of absorption due to the phase change within the material is used to limit the heat conduction of the material.

  • As we learned in Daegu subway fire accident, fire in the railway tunnel is prone to develop to large disaster due to the limitation of smoke control and smoke exhaust. In railway tunnel, in order to ensure fire safety, fire prevention and fighting systems are installed by quantitative risk assessment results. Therefore, in this research, developed the program to establish quantitative risk assessment and suggested quantitative safety assessment method including fire scenarios in railway tunnel, fire and evacuation analysis model, fatality estimate model and societal risk criteria. Moreover, this method applys to plan preventing disaster for Honam high speed railway tunnel. As results, we presented the proper distance of escape route and societal risk criteria.

  • We have conducted a numerical simulation under three-dimensional unsteady conditions in order to analyze the effect of flow and CO₂ mass transfer according to the distance between the CO₂ nozzle of CO₂ fire fighting system and the rear wall in a protection space. Flow fields and CO₂ concentration fields were measured. The different recirculation flow form and wall jet was developed according to increasing the distance between CO₂ nozzles and rear wall. In all the case, CO₂ mass transfer was generated toward the center of a protection space from each walls, but the CO₂ mass fraction of front and rear areas based on CO₂ nozzles showed higher or lower by increasing the distance between CO₂ nozzle and rear wall.

  • This study analyzed the current Urban Disaster Management System(UDMS) and proposed improvements, focusing on fire-fighting. We learned the problems with the UDMS empirically, conducting a survey intended for officials in fire station in various prefectures include big city, 6 metropolitan city and Gyeonggi-do. The problems with the UDMS were classified mainly into problems with law operating system, administration system and systematic countermeasures. As a result, it was found that regions that include Seoul and other big cities manage urban disasters better than the prefectures of which Gyeonggi-do and others are parts Consequently, it is desirable to cater appropriate Urban Disaster Management Systems into each of the two parts, one for big cities and the other for prefecture.

  • This study aimed to assist the improvement of organizational commitment and the preparation of an action plan regarding support from the organization by examining the effects of organizational culture types and perceived organizational support on firefighters' organizational commitment. To this end, 205 fire-fighting officers from the northern area of Gyeonggi-do were surveyed using the purposive sampling method. The results demonstrated that among organizational culture types, the perception of group culture, rational culture, and organizational support held by firefighters had a significant influence on their organizational commitment. Based on these results, this study suggested various support plans at the organizational level for stimulating group culture and rational culture among firefighters, and improving organizational commitment.

  • The purpose of this study is to understand the impact of integrated art therapy on the life meaning of new firefighters. The subjects of the study selected 108 newfirefighters to be hired as part of the new training center in South Gyeongsang Province. Out of 108 participants, consisting of 54 volunteers, conducted an integrated art therapy program once a week, 60 minutes each, and eight sessions. Research tools carried out pre - and post-inspection testing using a scale of meaning in life. For data analysis, t-test was conducted using SPSS 22.0 program.The study found that integrated art therapy using semantic therapy had statistically significant differences in meaning in life.The experimental group has made positive changes in its pursuit of meaning, finding meaning, and discovering meaning in life rather than in control groups. In other words, the new fire fighting public officials' ability to positively change in difficult situations, adapt to the environment, and overcome difficulties was improved. In particular, he showed changes such as realizing the importance of people and life, clarity of purpose and efforts to change himself. Therefore, it is necessary to carefully review the fire school program aimed at fostering firefighters with a balanced body.
