It is natural that The government should be responsibility for the fulfillment of obligation to prevent a notional life, accurate rescue and first-aid from various calamities. Although, The government policy is established a foundation that is reventing a national life and a property from the calamity with deciding of the fire line, that is not satisfied with taking precautions against a calamity. In case of the calamity there is always pointed the confrontation procedures, especially, In case of crisis The government is lacking to come to an developed country on account of system of the emergency rescue and first-aid. The prevention and provision are the most important thing with reference to a confrontation of the calamity. But calamity is happened without warning, so We should establish line of prompt rescue and first-aid lately that is very important thing. The First, We should get the single line of the rescue and first-aid through a integration and elimination in terms of a law of the emergency rescue and first-aid, but also we strengthen a line of a scene confrontation ability and speciality. To raise awareness of improving a rescue and ability of first-aid, through reinforcing the human and material equipment of The 119 rescue party to charge of emergency rescue and first-aid in effect.

The placement of Korean fire-fighting administrative power in urban areas shows regional unbalance. In an ideal system, all citizens would be provided with equal fire protection and rescue services, but this is usually difficult to realize due to regional conditions or budget problems. In the case of Busan Metropolitan City, we deduced that it is impossible for half of the buildings to receive rescue services within 5 min, and the conditions are much worse for areas with long or wide fire-fighting service regions. The approach vulnerability for the existing emergency rescue squad locations was assessed. The results revealed that if a rescue team's location is shifted, the improvement effect will be virtually insignificant because of their geographical position. Therefore, this study suggests the establishment of additional rescue squads. It is proven that adding 5 rescue centers in the following locations could solve the problem of approach vulnerability: Bukbu, Gangseo, Geumjeong, Gijang, and Haeundae, in order of effectiveness. The number of buildings in the areas is 53,546.

In this study, the 1/35 reduced-scale model experiment were conducted to investigate designed ventilation effect on the smoke movement at rescue station fire in railway tunnel. A model tunnel with 2 mm thick, 10 m long, 0.19 m high and 0.26 m was made by using Froude number scaling law. The cross-passages installing escape door at the center were connected between incident tunnel and rescue tunnel. The n-heptane pool fires with heat release rate 698.97W were used as fire source. The fire source was located at the center and portal of incident tunnel as worst case. A operating ventilation system extracted smoke amount of 0.015 cms(cubic meters per second). The smoke temperature and CO gas concentration in cross-passage were measured to verify designed ventilation system. The result showed that, at center fire case without ventilation, smoke did not propagate to rescues station. In portal fire case, smoke spreaded to rescues station without ventilation. But smoke did not propagated to rescues station with designed ventilation.

This study is to analyze the effect of rapid rise in the rescue activity of suffering on the increase of reactive oxygen species. There is no study that tested the change rate of reactive oxygen species according to the rapid rise in 119 rescue workers, so we want to check the symptoms that appear in rescue workers' bodies. There were 5 subjects, and B, C, and E showed similar values before and after diving: 0.41µmol/L, 0.11µmol/L, and 0.87µmol/L, respectively. However, in subject D, the level of active oxygen rise before and after diving was significantly higher at 1.41µmol/L, which is believed to be due to increased anxiety caused by poor underwater visibility and increased fatigue during rapid ascent after underwater rescue activities. Subject A showed a significantly low increase in active oxygen before and after diving at 0.07µmol/L. The reason seems to be that A is 54 years old and has the most diving experience among the test subjects, and it seems that it is the result of receiving less stress from the poor watch due to the abundant experience of rescue activities as a 119 rescue worker and the skillful underwater activities. Fatigue and anxiety were both high at 4. It is thought that the psychological tension during underwater activities increased fatigue, and the turbidity of the underwater vision raised anxiet.

This study was performed to determine the effect factors in the survival of cardiac arrest patients. This study involved 4,092 cardiac arrest patients of K province, who were transported by 119 during 2010. The data collection involved using 119 rescue daily reports, cardiopulmonary arrest patients emergency treatment detail reports and 119 paramedics survival data. In conclusion, 119 rescue's interventions in the patients with pre-hospital cardiac arrest have significantly increased survival rates. 119 rescue's interventions included early defibrillation, oxygen supply, airway open, and intravenous access affected significantly survival rate. Therefore there is need to increase 119 rescue's interventions performance to improve survival rate of cardiac arrest patients.

The purpose of this study was to examine the effect of difficult endotracheal intubation education in the 119 rescue services. The subjects in this study were 60 members of the 119 rescue services that was under the umbrella of the Fire Service Headquarters of J province. A SPSS 14.0 program was utilized to find out the effect of tough tracheal intubation education on their relevant knowledge, self-confidence, academic self-efficacy and technical Performance in consideration of general characteristics. The findings of the study were as follows: 1. They showed a significant improvement in all the knowledge, self-confidence, academic self-efficacy and technical Performance after they received that education. 2. As for connections between general characteristics and knowledge before and after that education, there were significant differences in their knowledge according to gender and career of working in the hospital, and their rank and career of working in the hospital made a significant differences to their self-confidence. Their academic self-efficacy significantly differed with rank, career of working in the hospital and academic credential. There were significant gaps among them technical Performance Case 1 according to career of working in the 119 rescue services, and technical Performance Case 2 significantly varied with age and academic credential. There were significant gaps in technical Performance Case 3 according to career of working in the 119 rescue services and career of working in the hospital after that education was provided, and technical Performance Case 4 significantly varied with age and rank before and after the education was conducted. In conclusion, the kind of education programs that aim at stirring up the interest of the 119 rescue services in advanced airway and helping the members learn about tracheal intubation accurately with confidence is urgently required.

This paper offers a practical control scheme for driving mode transformation of a rescue robot already developed. The rescue robot, VSTR(Variable Single-Tracked Robot), has two driving modes, so can traverse untidy terrain and overcome obstacles such as stairs easily by use of timely driving mode transformation. Classical PI control scheme was used firstly for driving mode transformation, but stationary phenomenon, which might have a bad effect on the performance in real situation, came into existence. Therefore, we suggest a new controller, PI-based feedforward controller, which should be a good alternative for the problem, and compare it with other nonlinear control scheme.

Objectives : The aim of this study was to clarify the role of alcohol use disorders and acute alcohol consumption in suicide attempts by gender. Methods : Data of 1,152 suicide attempters(487 males and 742 females) who had visited an emergency center was gathered. Suicide attempts were categorized into three groups according to alcohol use: an alcohol use disorder group(AUD), an acute alcohol use group(AAU), and a no-alcohol use group(NAU). The intent and lethality of suicide attempts were evaluated by Suicidal Intents Scale and Risk-Rescue Rating Scale. Results : For Suicidal Intents Scale score, the male AUD group revealed a significantly lower mean score than the male AAU one. However, there were no statistically significant differences for female subjects across subgroups. With regard to the Risk-Rescue Rating Scale score, there were no significant differences for males, while the AUD group showed both the lowest highest rescue scores and lowest risk-rescue scores within female groups. Conclusions : AUD in females was more likely regarding impulsive suicide attempts with high rescue chances. Consuming alcohol might have different effect on suicide attempts by gender and our study shows that alcohol use is an important risk factor according to gender, particularly with regard to female suicide attempts.
