In case of an emergency such as a fire on a building and there is a need to evacuate the occupant in that building, it is important to have the guidance information effectively delivered to the evacuating occupants to guide them toward a safe direction using audio sensual media. And, it is also very important to prevent the evacuating occupants getting lost or falling astray, away from the direction toward safety. The purpose of this study, in this respect, is to examine the possible application of the precedent sound effect, with which the evacuating occupants may get a sense of the direction where the announcement comes from. With such an effect, an experiment was conducted to measure the extent to which people can hear the preceding and the following sound in terms of the acoustic pressure level changes and delay time changes, with a view to make the optimal evacuation-guidance announcement or sound. The optimal evacuation guidance sound (announcement) per each of the experimental indoors environments were as follows; 1) Regarding the optimal condition for the evacuation guidance announcement sound in the space of a lecture room, the direction of the advanced sound is positively recognized when the follow-up sound has the delaying time of 10 ms~50 ms in comparison with the advanced sound or when there is no difference between the acoustic pressures of the advanced and follow-up sounds or the acoustic pressure of the advanced sound is higher than that of the follow-up sound. 2) Regarding the optimal evacuation guidance announcement sound in the space of a hall, the advanced sound is positively recognized when the follow-up sound has the delaying time of 20 ms~60 ms in comparison with the advanced sound. 3) Regarding the optimal evacuation guidance announcement sound in the space of a gymnasium, the advanced sound is positively recognized when the follow-up sound has the delaying time of 10 ms~40 ms in comparison with the advanced sound or when the sound pressure of the advanced sound has a higher level than or the same level as that of the follow-up sound.

A total of 19 elevators for evacuation were installed in the Lotte World Tower and it is planned to operate the shuttle using the manual key from five refuge floors to the 1st floor in an emergency. In the event of a fire or other disaster, it is necessary to conduct intensive analysis to determine how much RSET reduction could be achieved using the evacuation elevator compared to the existing evacuation plans. When the optimal transportation sharing ratio by the evacuation elevators was 40% at the Lotte World Tower, the RSET of the evacuation scenario in parallel with the elevators in the entire building was calculated to be 1 hour and 2 minutes. The RSET of a conventional evacuation scenario (Walking along the stairs without using the elevators) was calculated to be 1 hour 29 minutes, therefore, the former evacuation scenario were found to have a shortening effect of approximately 27 minutes compared to the latter. On the other hand, to maintain this effect, each part of the evacuation route using the elevator must have the capability to protect the evacuee from any hazards caused by fires, such as smoke, flame, and radiant heat during the evacuation. Moreover, the evacuation route should be continuous from the residence position of the elevator user to the final evacuation site, and be recognized easily.

The purpose of this study was to investigate 119 rescue party's violence experiences and to analyze their responses of violence experiences based on the pre-hospital emergency medical field. Data were collected from the self-administered survey of 226 rescue party in Jeollabuk-do area in Korea from January 1 through March 2, 2009. The data were analyzed by descriptive statistics and logistic regression analysis using SPSS Win 12.0. The results were as follows: first, all of 119 rescue unit in the pre-hospital emergency medical field reported that they got violence experiences more than once a week, and 62% of rescue team were exposed to physical violence. Patient's factors that caused violence were drug abuse or alcohol(56.2%), on the other hand rescue party's factors were shortage of human resources. Second, 42% of the respondents replied that they did not have any educational experiences for prevention and coping methods about violence within 5 years. 77.4% of those surveyed indicated that they wanted to receive specific educations which can prevent and cope with violence. Third, the mean value of total violent response scores was 2.53, and emotional response score was 3.2, social response score was 2.22, and physical response score was 2.17. Fourth, violent response score related to general characteristics proposed that physical(t=-2.08, p=o.38), emotional(t=-7.13, p=.006), and total responses(t=-4.764, p=.000) were statistically significant. And emotional(t=4.257, p=.000) and total responses(t=8.1330, p=.000) related to age were also statistically significant. Finally, among current tenure qualification scores, social response(t=9.987, p=.012) and total score(t=8.130, p=.000) were statistically significant. Between fire departments, violent response score suggested that physical(t=9.987, p=.000), emotional(t=2.433, p=.012), social(t=6.738, p=.000), and total score(t=5.943, p=.000) were statistically significant.

Objectives: The purpose of this study was to reconsider the necessity of stroke-related educational programs by investigating early symptoms of stroke that emergency medical technicians (EMTs) may experience. Methods: An interview survey was carried out, targeting all EMTs 298 people who were working at 119 fire safety centers and local units in Jeollabuk-do province, from April 1 to 30, 2011. An interviewer administered questionnaire was used to obtain data on ETMs' demographic characteristics, educational level on stroke, and awareness level about early symptoms of stroke and treatment-related characteristics of stroke patients. Results: The results showed that 63.2% of those surveyed had completed the required educational programs on stroke during the past year. The level of awareness about early symptoms of stroke and assessment of stroke patients' condition was relatively high for women, those who were 30 years under, low position people, emergency service practitioners, emergency medical technicians, and people who have completed education, respectively. It was also turned out that 82.8% of those surveyed took stroke patients to the nearest hospitals first so that they could receive appropriate treatment. The level of awareness about early symptoms of stroke and assessment of stroke patients' condition in people who have completed education were higher than non-complete. The level of awareness about early symptoms of stroke was positively correlated with confidence, satisfaction and appropriateness in treatment of stroke patients. Conclusions: These results strongly suggest that it is necessary to operate specialized educational programs to enhance EMTs' appropriate awareness of the early symptoms of stroke and assessment of stroke patient's condition.

The purpose of this study is to evaluate the awareness and usability of descending life lines and simple descending life lines for fire situations in the accommodation of the public officials who are responsible for supervising the installation and maintenance of descending life lines and simple descending life lines. The main results of the study are summarized as follows. First, in comparison of the ability to distinguish between descending life lines and simple descending life lines, the majority of female public officers in general administrative services do not have the ability to distinguish between descending lifelines and simple descending life lines, so they should be able to improve their ability to distinguish descending life lines. Also, institutional strategies are needed to regularly receive education through the Safety Experience Center in order to prevent safety accidents such as falling in emergency situations. Second, as a result of verifying reusability of simple descending life lines by gender and occupation, most public officers with the exception of half of the firefighting officers were analyzed as having no ability to reuse the simple descending life lines. Therefore, it is necessary to change the relevant laws so that only the installation of descending life lines which can be used continuously is permitted, except for the simple descending life lines among the evacuation instruments to be additionally installed in each room of the accommodation. Third, in terms of the ability to perceive the maximum load of the descending life lines according to occupation, the perception ability of the rescuers was the highest and the perception ability of the fire service personnel was the lowest. In order to improve the perception abilities of the fire service personnel, it is necessary to strengthen the theoretical and practical education of descending life lines in collective education such as the command-enhancing training which is regularly carried out in fire service academy. Lastly, it is believed that it is more effective to conduct the experience training of the descending life lines by imagining the fire in accomodations rather than other facilities, because it is the location where fires are actually seen the most.

In April 2023, a wildfire broke out in Gangneung located in the east coast region due to the influence of the Yanggang-local wind. In this study, GIS-based RUSLE(Revised Universal Soil Loss Equation) and SEMMA (Soil Erosion Model for Mountain Areas) were used to evaluate the erosion rate due to vegetation recovery in a small watershed of the Gangneung WUI(Wildland-Urban Interface) fire. The small watershed of WUI fire has a low altitude range of 10-30 m and the average slope of 10.0±7.4° which corresponds to a gentle slope. The soil texture was loamy sand with a high organic content and the deep soil depth. As herbaceous layer regenerated profusely in the gully after the wildfire, the NDVI (Normalized Difference Vegetation Index) reached a maximum of 0.55. Simulation results of erosion rates showed that RUSLE ranged from 0.07-94.9 t/ha/storm and SEMMA ranged from 0.24-83.6 t/ha/storm. RUSLE overestimated the average erosion rate by 1.19-1.48 times compared to SEMMA. The erosion rates were estimated to be high in the middle slope where burned pine trees were widely distributed and the slope was steep and to be relatively low in the hollow below the gully where herbaceous layer recovers rapidly. SEMMA showed a rapid increase in erosion sensitivity under at certain vegetation covers with NDVI below 0.25 (Ic = 0.35) on post-fire hillslopes. Gentle slopes with high organic content and rapid recovery of natural vegetation had relatively low erosion rate compared to steep slopes. As subsequent infrastructure and human damages due to sediment disaster by heavy rain is anticipated in WUI fire areas, the research results may be used as basic data for targeted management and decision making on the implementation of emergency treatment after the wildfire.

Purpose : To check the legal relation between rescue team and patient as well as legal responsibility for patient's damage intentionally or erroneously caused by rescue member, a public official, in the performance of relevant job ; to prevent legal dispute over rescue team and to present program for fair settlement of dispute and equitable and feasible burden of damage. Method : First, the legal principle of Civil Law, Criminal Law and Administrative Law related to the theme of this research will be investigated around research by literature. Second, the case of dispute related to rescue team will be introduced. Result: 1. If 119 rescue members as a public official intentionally or erroneously cause damage to patient in the performance of job, they shall bear civil, criminal and administrative responsibility. They shall bear civil responsibility for indemnity for damage due to default or tort. The typical criminal responsibility includes accidental homicide arising out of duty, preparing falsified official document, dereliction of duty, etc. In the administrative side, the state is responsible for indemnity for peculiar status of the rescue member, public official. 2. Though raising civil petition or legal dispute over unsatisfactory rescue service may be reasonable to guarantee the right of nation, such action may cause stress to rescue member as well as may lead to mental shrinking and defensive attitude only to take the basic first aid treatment which has low possibility of mistake instead of active first aid treatment so as to avoid legal responsibility. 3. The program that may prevent legal dispute over 119 rescue team includes expansion of manpower specialized in first aid treatment, enhancement of education on legal environment, development and application of standard job guideline, formation of mutual trust with patient, detailed explanation, preparing and keeping minute record, improvement of the rescue members' ability of first aid treatment and development of medical instruction mode. Conclusion : The best policy is to prevent legal dispute. If it is impossible to basically exclude the possibility of dispute, however, we need to make effort to minimize the occurrence, settle fairly and divide damage equitably and feasibly. To improve the preventible death rate of our first aid system to the level of advanced country, 119 rescue team which is in charge of the stage before hospital needs to positively enforce special first aid by improving the qualitative level of rescue service and to strive to prevent legal dispute that may occur in the process.

Indoor fire simulators have been used to analyse building safety in the events of emergency evacuation. These applications are primarily focused on simulating evacuation behaviors for the purpose of checking building structural problems in normal time rather than in real time situations. Therefore, they have limitations in handling real-time evacuation events with the following reasons. First, the existing models mostly experiment the artificial situations using randomly generated evacuees while real world requires actual data. Second, they take too long time in operation to generate real time data. Third, they do not produce optimal results to be used in rescueing or evacuation guidance. In order to solve these limitations, we suggest a method to build an evacuation simulation system that can be used in real-world emergency situations. The system performs numerous simulations in advance according to varying distributions of occupants. Then the resulting data are stored in DBMS. The actual person data captured in infrared sensor network are compared with the simulation data in DBMS and the querried data most closely is provided to the user. The developed system is tested using a campus building and the suggested processes are illustrated.
