Firefighters performing disaster response activities such as Fire Suppression Rescue First Aid in fire are being exposed in various adverse factors, heat, smoke, toxic gases, emotional stress, biological toxic factors and physical overload by unnatural ergonomic posture required for firefighters. But so far, there is the study for this problem only separately. There is no study about comprehesive analysis of exposed adverse factors in fire-related disaster response activities and countermeasures. The purpose of this study is to contiribute to solving the health problems and prevention of accidents of firefighters by extracting hazardous agents in disaster such as fire and by proposing countermeasures. After analyzing circumstances such as fire-suppression, rescue first aid and life-environment, exposure factors of fire are derived and exposure status is suggested according to physical chemical biological psychological aspects. The countermeasure against the noise of the physical exposure factors are proposed. The countermeasures such as protective equipment and clean room in chemical factors, infection prevention education, vaccination and periodic check system in biological factors, PTSD alleviation booth and mentoring in psychological factors are proposed.

Fire fighter are exposed to the situations which are hard to predict due to continuous and accidental changes which hinder their fire fighting activity. As these threats of safety accident act as fear factors, they are doing insecure fire fighting activities. Therefore, as unclear and abnormal risks of working environment such as the riskiness of expansion of disaster, instability, obstacles of activities, abnormality, urgency, etc. increase, safety accidents are caused. This study analyzes the actual condition of safety and health and awareness of fire fighter who are exposed safety accidents during their fire fighting activities and utilize such result as the basis data to secure safety of fire fighter, keep efficient safety control and prevent accidents. The results of analysis are as follows. As rescue works among all fire-fighting works shows the highest emotional stabilization and the highest post-traumatic stress disorder is shown in fire sergeant level positions, and fire fighters whose working period is 10-15 years, reinforcing safety training to long-term workers is necessary. As the result of survey regarding safety awareness, the highest awareness level was shown in fire sergeant level positions, and fire fighters whose working period is over 20 years, and when it comes to operation of fire fighting equipments, fire-fighting workers and workers having 1-4 years of working period showed high safety awareness. The more serious injury in a fire fighter experienced as the first injury after working as a fire-fighter, the more cause-and-effect relationship was shown between personal physical condition and work, and it is shown as obstacles of fire fighting activities and affects to post-traumatic stress disorder. Moreover, as after-work off duty activities also affect to official disaster, systematic improvement of working environment is required. Occupational medical work compatibility evaluation considering the distinct characteristics of works to secure fire-fighter' health care together with fire-fighting capability is shown to be necessary.

The aim of the present study was to evaluate the effects of two well-known natural antioxidants, vitamin C (VC) and vitamin E (VE), on the antifungal activity of honokiol against Candida albicans. The broth microdilution method was employed to test the antifungal activities of honokiol with or without antioxidants in the medium against C. albicans strain. Intracellular reactive oxygen species and lipid peroxidation were determined by fluorescence staining assay. Mitochondrial dysfunction was assessed by detecting the mitochondrial DNA and the mitochondrial membrane potential. We observed that VC could significantly potentiate the antifungal activities of honokiol while VE reduced the effectiveness of honokiol against C. albicans. In addition, VC accelerated honokiol-induced mitochondrial dysfunction and inhibited glycolysis leading to a decrease in cellular ATP. However, VE could protect against mitochondrial membrane lipid peroxidation and rescue mitochondrial function after honokiol treatment. Our research provides new insight into the understanding of the action mechanism of honokiol and VC combination against C. albicans.

Recently, in Korea, if a very large forest fire occurs due to the people's carelessness, it is of great interest because it spreads into a large forest fire. If a wildfire spreads and becomes large, it will inflict great damage (appointment and property), and the damage is irreversible. The best way to extinguish a wildfire is to prevent it before it occurs. If a forest fire occurs due to a failure in prevention, the early firefighting activities to prevent the progress of the forest fire by promptly dispatching it by reporting it and approaching the site as soon as possible should now be managed with a systematic integrated management system. To do so, it is necessary to prepare a preventive system, such as issuing warnings for each weather condition by the Korea Forest Service, consisting of cooperation (support) activities for forest fire prevention by related organizations, etc. In order to minimize the loss of precious lives and forests, measures have been taken to establish a system, to establish a prompt and accurate situation reporting system, and to establish an integrated command system (ICS) for on-site commanders.

Purpose: The purpose of this study is to determine potential differences in pre-hospital cases of cardiac arrest and drug Intoxication between elderly group and non-elderly group on local emergency activity sites of rescue 119 team for those cases, so that it can provide useful reference materials for a system of corresponding emergency medical services. Methods: Patients with cardiac arrest and drug intoxication in the elderly and the non-elderly group were analyzed by analyzing the Ambulance Run Report for 3 years from January 2007 to December 2009. Results: According to analysis on potential differences between elderly and the non-elderly group, it was found that there was no significant difference between elderly cases (evacuated to hospital due to cardiac arrest and drug poisoning) and non-elderly cases in year of onset (p = .247), quarter of onset (p = .813), sex (p = .235), consciousness state (p = .126), place of onset (p = .215) and number of first aid services (applied to emergency cases) respectively, but there were significant differences between elderly cases and non-elderly cases in guardian availability (p = .042), time zone of onset (p = .050), distance from the site of onset (p = .278), type of onset (p = .000), number of first aid services depending on distance of evacuation (p = .008) and effectiveness of emergency care (p = .003) on statistical basis. Conclusion: It is important to establish a system of early emergency case reports for rational emergency case management with lower mortality; shorten distance from the site of onset at each time zone of onset in emergency cases; employ more emergency team members; facilitate firsthand / secondhand medical instructions for emergency teams in specialized emergency care depending on distance of evacuation for each kind of onset (elderly group vs. non-elderly group); and improve rate of resuscitated emergency cases by extending the scope of works for emergency medical technicians into wider applications, so that it will be possible to take timely and appropriate measures for emergency settings of ever-increasing aged population in near future.

To enhance the quality of disaster management service, the paradigm shift is necessary from the supplier-centered approach to demander-centered approach. In this paper, demander means all the policy actors that participate in the field of disaster such as central & local governments, emergency rescue systems, civil volunteer groups as well as the disaster victims. In this study, we analyze the current problems of disaster management service in demanders' point of view through in-depth interviews and then address suggestions based on each entity's recognitions and understandings related. The results are as follows: 1) Lack of systemicity in the current disaster management service. 2) The mutual distrust and understanding among the policy actors participating in the disaster site. 3) In the field of disaster, not only the disaster victims but also people related to entities are deprived of a stable living due to a long period of rescue activities. Furthermore, the conflicts derived from allocations of the aid fund can bring about the collapse of local community involved in disaster. 4) The life of the disaster victims that have been damaged mentally and financially is earnestly necessary to be conveniently served by disaster management service.

Interest in mountain accidents among the technical trends of disasters in Korea is increasing continuously. When accidents occur, the most common methods are location tracking and accident reporting using smartphones, and rescue activities are being carried out by using them. In this paper, we proposed an improvement of wireless safety system for mountain climbing safety using 447 FSK. Using the 447 MHz band transmitter / receiver, it accumulates position coordinates and data through position transmission and rescue signal transmission in case of anomalies. If a sender is out of the threshold of the set area range, a danger warning notification can be generated to quickly exit the danger zone. Provide services. In addition, it is considered that the health condition of the sender is continuously checked and the receiver is warned when the specified threshold is exceeded, so that it is possible to respond to the sender's disaster.

This study was to analyze the effects of sudden rise in cortisol and human symptoms in the situation of rescue at river, The experimental results are as follows. The subjects were A, B, C, and the values of cortisol elevation before and after diving were 6.30ug/dl, 6.50ug/dl, and 6.57ug/dl, respectively. However, in the subject D, the elevation of cortisol before and after diving was significantly elevated to 11.00ug/dl. The reason for this is thought to be the depletion of physical strength through weighty due to the inferiority of the underwater view and tense during the sudden rise. The subjects E showed significantly lower cortisol elevation before and after diving, as 4.28ug/dl, because the age of E was the youngest of the subjects and the anxiety was low due to abundant experience of deep sea diving. Fatigue is 7 to 8, anxiety is 7 to 9, Both showed high values. Psychological strain increased fatigue in underwater search, and poor visual field seemed to increase anxiety. The research results will be provided as empirical data on the safe underwater search activities of rescuers.

There are concerns about the influence of the gust wind caused by helicopters affecting the moving vehicles while hovering over the road during rescue activities. For the understanding of such complicated flow. numerical simulation of a rotor hovering above the ground has been carried out, changing the rotor/ground clearances. The rotor thrust is kept constant. and the rotor control is determined by trim adjustments incorporated into the CFD algorithm. Collective pitch angle and the required power decreases with the rotor/ground clearance which agrees with experience. Changes of the flowfield near the rotor with regard to the rotor height are investigated based on the calculated results.
