This paper describes a cause of fire accidents on power system fire DC electric traction vehicles. We investigated fire scene of power line for DC electric traction vehicles. From analysis results, the cause of fire on power line turned out line to ground fault between a feeder of electric power services(pantagraph) and DC electric traction vehicle roof. Fire accident of DC electric traction vehicles be assumed that electric sparks had been produced between the pantagraph and the power line conductor by repetitively making contact and separation, maybe if some material like branches get in between connecting rod it makes progress line to ground fault. ZnO arresters are widely used to protect DC electric traction vehicles against overvoltages caused by lightning or switching surges. However, the arresters are deteriorated by commercial overvoltages and/or lightning one. The deteriorated arresters could lead power failures, such as line to ground fault by a thermal runaway resulting from the increases in leakage current even in a nominal power system voltage. Finally, the power failures would be causative of the fire accident.

As a result of trying the various manufacturing methods considering the reality of manpower and equipments with this manual, the following standardized procedures and contents can be suggested. (1) Since tools presenting Rock-Drill data must formalize the order of explanation although explainers are different, it will be valid that it is configured by existing power point method rather than by web document type. Composition of contents are selected on the basis of defence card and survey and then 8 items including initial screen, peripheral conditions, mobilization route, general conditions, use and structure by floor, department of vehicle consideration in activities and end screen are included. (2) Making methods and cautions of data included and used in power point are as follows ; - It was most effective that objects of fire fighting and location of neighboring fire fighting water were expressed by electronic map and drawing of inner building was made by scanning it after paining general architecture drawing(plan by each floor) rather than using drawing tools of EXCEL program or CAD drawing. And it was helpful to simplify contents of architecture drawing to wall, stairs and gate in understanding them. - Photographing of video data should be taken to show available fire fighting facilities in fire, use of planned space and the whole inner structure of each floor from the inside of fire fighting buildings and to display play time between 10 sec. and 1 min, for obstacles to distance from adjacent buildings or passage of special vehicles and fire fighting water from the outside of the building. - File format of video data taken in this way is most suitable to use wmv(window media video) or asf(advanced streaming format) type in consideration of time required for export, screen quality, file capacity and play type in Rock-Drill through network. - Still screen(photo) is more effective to express the department of fire fighting vehicles or other equipments than using video. (3) In configuration work of power point, hyper link was used most and configured to see any part at any situation like web document and then uniformity of presentation order of power point was complemented. (4) In case of sales facilities with the area of $35.557m^2$, the time of 22 hours and 30 minutes for five days was taken with five persons. Therefore, when eight-hour works a day were calculated, the whole process of video work for Rock-Drill can be finished with three day works.

Ambulances are an important element of pre-hospital emergency medical services, and also an important space for improving the work efficiency of paramedics. Paramedics use the interior environment to maximize the capabilities of the space, but ambulances need to be improved to help with the responsibilities of paramedics. A Seamless space was constructed in accordance with the placement of first-aid emergency medical equipment and drugs, and a patient room was loaded in the interior space of an ambulance. This study was to improve the treatment space of an ambulance to improve the efficiency of work by paramedics The new design provides safety and efficiency for emergency medical services through planning of interior storage suitable for the duties of paramedics and through identification and analysis of the problems in the environment.

Purpose: This study aims to provide essential data for developing educational methods and content, tailored for the prehospital field situation, by analyzing the effects of education regarding the management of cardiac arrest. Methods: This study is a primitive experimental study of 55 new firefighters in C Fire Service Academy. Data were collected from the training which was imparted using the CPR virtual reality simulation program (CBS 2.0) in accordance with COVID-19 quarantine rules and social distancing. Data were analyzed utilizing SPSS version 25.0. Results: After VR simulation training, knowledge about performing CPR (14.85) and self-efficacy (4.12) were significantly high (p<.001). Learning immersion was also high (3.99±0.59), but learning satisfaction was even higher (4.34±0.62). Depending on the recruitment field, firefighters showed higher learning immersion (4.04±0.58 vs 3.68±0.63) and self-efficacy (4.16±0.55 vs 3.91±0.84) than 119 EMTs' but, there was no significant difference between them. In contrast, The quality of performance of CPR by EMT's was significantly higher than that of firefighters (p=.025). Depending on previous simulation experience, there was no significant difference among dependent variables. Conclusion: Virtual reality simulation shows positive results in learning immersion, learning satisfaction, self-efficacy, and performance of CPR. Therefore, we propose that virtual reality simulation training can be a new educational paradigm.

Recently, there is a growing need to review compliance with legal requirements to ensure fire safety as the number of fires caused by noncompliant fire safety facilities in high-rise buildings has increased. While there are a large number of apartment buildings in Korea, there is a lack of review on fire safety facilities' compliance with fire safety requirements. The reason for this lack of review despite apartment buildings causing deaths due to their structural features in the event of a fire, lies in the misinterpretation of legal provisions as the Building Act and the Fire Services Act are mixed up; a final inspection when fire safety facilities are unnecessarily installed or missing could result in significant losses in terms of finances and time. Therefore, this study developed a checklist that makes it possible to review mixed-up legal requirements for fire safety facilities simultaneously, and examined the importance and current level of each item through IPA (Importance Performance Analysis). Based on these results, this study intends to develop a manual that considers its applicability to construction practices and contribute to reducing construction companies' fire safety inspection risks.

Purpose: The emergency medical service (EMS) system in Japan is similar to that in Korea. This study reviewed the development of paramedics who are major personnel in the respective EMS system of their country. Methods: We searched law for paramedics and publications in J-stage, MEDLINE and the webpage of Japan's Fire and Disaster Management Agency. Results: Paramedic training had started in Japan in 1991, and most paramedics were employed in fire departments. In Japan, ambulances belonging to fire department are staffed by a three-person unit, including at least one paramedic. Medical control advisory boards were established in all Japanese prefectures in 2003 with the purpose of upgrading the activities of ambulance personnel, including paramedics. The scope of paramedics' work has been widened owing to the continued efforts of medical control advisory boards. This allows them to perform invasive procedures including tracheal intubation, intravenous line placement, and epinephrine administration under medical control of a physician. Conclusion: As paramedics' responsibilities expand, further development of the paramedic role and an effective medical control advisory board system are imperative both Korea and Japan.
