Safety related workers, such as firefighters, have to wear a protective helmet. The Development of Helmets for safety is in progress to promote the wearable device industry. Several accidents caused by negligence in recent days have raised public attention to safety. For this reason, the amount of national budget funding for the study of fire-fighting and smart safety helmets has increased. However, most previous studies have focused on safety, rather than the application of new technologies based on physical attributes, especially the characteristics of head shape and size, even though fire helmets play the critical role of protection from flames and external shocks etc. in an emergency. This paper will present the smart technologies and newly developed designs for safety helmets that are personalized for each firefighter, based on the characteristics of their head, and will help a rescue operation to be much more safe and efficient.

This study aims at developing ergonomics patterns for the sleeve of structural firefighting protective clothing through 3D motion analysis in order to ensure efficiency and safety of firefighters who are exposed to harmful environment at work. A new research pattern was developed by applying the total results of 3D motion analysis, changes of body surface length measurements, and 2D data on 3D body shape analysis on the size 3 patterns of the existing coat sleeve. For the sleeves, we used the body surface length of the range of shoulder's flexion and the joint angle of the range of wrist's ulnar deviation. And for the production of structural firefighting protective clothing using the research pattern, we recruited a recognized producer of structural firefighting protective clothing designated by KFI. Unlike everyday clothes, structural firefighting protective clothing should be able to fully protect the wearers from the harmful environment that threatens their lives and should not cause any restrictions on their movement. Therefore, the focus of research and development of such protective clothing should be placed on consistent development of new technologies and production methods that will provide protection and comfort for the wearer rather than production cost reduction or operational efficiency. This study is meaningful as it applied 3D motion analysis instead of the existing methods to develop the patterns. In particular, since 3D motion analysis enables the measurement of the range of motion, there should be continuous research on the development of ergonomics patterns that consider workers' range of motion.

National interest in nuclear safety continues to increase. One of the policies that the government is pursuing is to change a temporary position to a permanent position for irregular special security guards of Nuclear power plants. At this point in time, it is urgent to discuss the method of their physical fitness test because duties of special security guards such as arrest and self-defense, unarmed defensive tactics, proficiency with semiautomatic rifle, etc, demands a lot of physical fitness. The purpose of this study is to analyze the physical fitness tests of police, firefighters and soldiers in Korea, US and Japan through literature review. After that, a new fitness test method suitable for special security guards of nuclear power plants was derived through expert meetings. This study also suggested a guideline to analyze the fitness test results so that the developed fitness method can be introduced to the field. For this purpose, physical fitness tests were conducted on 74 subjects. Based on the results of the experiment, the expected records of special security guard fitness tests were presented.

In order to foster rapid disaster response and public life protection, National Emergency Management Agency has been trying to spread 'Emergency Rescue Standard System' on a national scale since 2006. The agency has also intensified management of firefighter's safety on disaster site by implementing danger predication training, specialized training and education and safety procedure check as a part of safety management officer duties. Nevertheless, there are limitations for effective fire fighting steps, such as damage spreading and life damage due to unawareness of illegal converted structure, structure transformation by high temperature and nearby hazardous material storage as well as extemporary situation handling endangered firefighter's life. In order to eliminate these limitations there is a need for an effort and technology application to minimize human errors such as inaccurate situational awareness, wrong decision built on experience and judgment of field commander and firefighters. The purpose of this study is to propose a new disaster response model which is applied with geospatial information. we executed spatial contextual awareness map analysis using fire-fighting vulnerable zone model to propose the new disaster response model and also examined a case study for Dalseo-gu in Daegu Metropolitan City. Finally, we also suggested operational concept of new proposed model on a national scale.

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.

This study not only investigates emergency medical personnel's posttraumatic stress(PTS), social support, work burden, and coping style but also identifies related factors which were exerted influence on PTS and active coping method of emergency medical personnels among the firefighters. The data were gathered from 143 emergency medical personnels who were receiving training. The data were collected by IES-R, consisting of twenty-two questions that determine the level of PTS, method used in Cho's research(2000) that deal with work burden, method used in Oh's article (2006) relating to social support, and sixty-two questions that deals with coping methods. Then the data gathered were analyzed using SPSSWIN 14.0 program. PTS of general characteristics showed significant difference in age, marriage status, education, and position. High risk group of PTS was 74(51.7%). Work burden, active and passive coping method, and three symptoms in PTS are significantly high(p=0.000) in high risk group. PTS was correlated with work burden(r=0.508, p=0.000), active coping method(r=0.375, p=0.000), and passive coping method(r=0.505, p=0.000) but not with social support. Related factors of PTS were work burden(0.371) and passive coping method(0.366). Also related factors of high risk group of PTS were work burden(odds ratio=1.064, 95% confidence interval:1.031-1.103) and passive coping(odds ratio=1.050, 95% confidence interval:1.022-1.080). Related factors of active coping method were PTS(0.392) and social support(0.158). To minimize the PTS of emergency medical personnels, the new policy should decrease their work burden and passive coping method and strengthen the social support to encourage active coping method.
