Purpose: The purpose of the study is to check up the status of 119 emergency control centers usage. Therefore, the status of use of 119 emergency control centers and the incidence of pre-hospital cardiac arrest patients were investigated. Methods: The emergency activity daily reports and first aid diaries of 119 emergency control centers from January to December 2018 were reviewed. For more accurate status analysis, Among the first aid guidance received in the emergency rescue standard system, the cardiopulmonary resuscitation guide log was reviewed. Results: In 2018, the total usage of the 119 emergency control centers was 1,358,356 calls, hospital guidance werethe most commom (n=629,676, 46.4%), followed by first aid (n=428,027, 31.5%), disease consultation (n=170,238, 12.5%), medical oversight (n=111,188, 8.2%), and interhospital transfer (n=5,052, 0.4%). Regarding the user number per 1,000 persons, Jeju was the greatest at 48.0, whereas Changwon was the lowest at 13.0. A total number of dispatcher-assisted cardiopulmonary resuscitation was 12.181. The time from report to chest compression were 156.2±80.8 seconds for those with previous cardiopulmonary resuscitation training and 168.0±79.3 seconds for those without such training (p<.05). Conclusion: The ratio of first aid instructions, including dispatcher-assisted cardiopulmonary resuscitation, among total usage of the 119 emergency control centers increased. Therefore, additional efforts are required to improve the quality and expertise of information provided through the 119 emergency control centers.

Purpose: This study compared the relative importance of educational content, teaching methods, and evaluation methods in the patient assessment curricula of 119 emergency medical technicians (EMTs). Methods: First, we identified the educational content, training hours, and teaching and evaluation methods of the existing patient assessment curriculum based on the National Competency Standard learning module. Second, we surveyed 30 EMTs affiliated with 119 services using the Analytic Hierarchy Process (AHP) method. Subsequently, we compared the differences between the current curriculum and the AHP analysis results. Results: Currently in operation, the "Advanced EMT Course" comprises three learning modules: assessment of patient status, scene size-up and triage, and assessment using monitoring devices. Among these, content related to the assessment of patient status received the most allocated time and was deemed the most important according to the AHP survey results. Conversely, while less time was allocated to scene size and triage compared with assessment using monitoring devices, the former was assessed as more important than the latter in the AHP results. Furthermore, scenario-based team training and procedure-focused individual practice were evaluated as relatively important teaching methods, while practical examination using a checklist was deemed the most appropriate evaluation method for all learning content. Conclusion: To improve the patient assessment curriculum, we propose adjusting teaching hours and introducing new teaching and evaluation methods based on the results of relative importance. The proposed improvement plan will contribute to enhancing the competency of 119 EMTs.

After permission progress about the inspection of the design ascertain whether it is safety property Mayor/Do governor permits within the laws and their qualification. Accordingly, Korea Fire Equipment Inspection Corporation be come specialization about the design, inspection of construction completion. A inquire purpose of Fire Service Act be considered fitness. Subject by which the Korea Fire Equipment Inspection Corporation is entrusted, subject by which the a non-probit corporation in The Civil Law be possible to entrusted in separate. In this case, because of the level of one's technique and facilities are important, to limit as a nonprobit corporation in The Civil Law give rise to trouble. Consequently; established a business corporation, which the level of one's technique and facilities, in accordance with The Commercial Law can assign inspection of construction completion. The contents of the Fire Services Act is caused by the historic growth of hazardous facilities's safety management. Because we decide on a course about completed inspection of hazardous substance, it is needed that adjust the task performed by a corporation of the exert skill and the duty performed by the task that a authorized corporation on the civil law or the commercial law To adjust the duty, the Fire Service Act, that is suitable to the purpose and principle, should constitute a measure of the duty. With the object of insure the safety of the hazardous substance, when the fire survice act establish a corporation of the expert skill. There is the will of lawmakers that need organization to have the power of the professional technology.

As services for citizens' security and protection offered at the national and social levels become more widely recognized across society, the more frequent use of ambulances by patients with both minor and major injuries is being observed. However, the number of safety accidents during transport by ambulances, which are responsible for the prompt transport of patients, has been rising in tandem with the increase in their use. This is due not only to their inconspicuousness both on the road and in other environments where these vehicles are exposed, but also to the high chance of secondary accidents, putting the lives of both patients and emergency responders at risk. It is important to study and develop designs that guarantee protection against safety accidents, noting that ambulances are completely exposed and unprotected on the road on cloudy days and at night-time. In addition, by identifying colors and design motives that enhance the conspicuity of ambulances from a distance and increase their security, emergency responders and patients can be safely protected, the identity of the ambulances can be reinforced and modernized, and the sense oppression which can be visually imposed on patients in a psychologically unstable condition can be eased. Against this backdrop, this study presents the process involved in deriving the exteriors of ambulances in Korea, including their colors and patterns, by examining the established global best practices and identifying the need for more studies into colors, even unconventional ones, that improve their safety.

This research compares and analyzes evacuation time depending on the change in stair width in case of fire at Goshiwons. For this, a simulation has been conducted based on possible evacuation time according to the calculation method for the number of people admittable to a specific target for fire fighting equipped with accommodation. Currently, Gosiwon, which is classified as an accommodation facility (a total floor area of 500 m² or more), uses blind spots prescribed by the Fire Services Act, Building Act, and Parking Act to build a high-rise building on a small area of land, and most Gosiwon is transformed into a modified accommodation. This is in line with the owner's operating profit, so it is expected to show a continuous increase. Securing the golden time of Gosiwon evacuation time is the last bastion of Gosiwon residents who belong to the economically disadvantaged in our society, and we hope this study will serve as a starting point for discussions on revising related laws and regulations to establish a social safety net As a result of the evacuation simulation analysis, the evacuation time was the least when the width of the group and the evacuation stairs were expanded to 200cm, and the evacuation time of the existing building was reduced by up to 166.3 seconds by comparing 648.4 seconds and scenario 6. This analysis can be meaningful, in that the width of the evacuation stairs revision of related laws and regulations for the safety of multiplex available premises.

Recently, urban structures including buildings are becoming increasingly large and super high-rise in order to make human life more convenient. As the number of super high-rise buildings increases, however, the risk of fire and other disasters is increasing. Especially, it is expected that deaths and injuries will be tremendous than imagined if the evacuation guidance is not provided promptly and precisely for the occupants in case of a fire in super high-rise buildings. Therefore, rapid rescue should be done for those who are in need of residence or rescue in the building. To do this, identification of the size and location of people inside the building should be preceded. To do this, first, we conduct a preliminary study on existing location tracking technologies to identify occupants. Based on this, in this paper, we will study how to improve evacuation time in case of a fire in super high-rise buildings. For this purpose, we utilize the location tracking technology to identify the number of people in real time and improve the density when a disaster such as a fire occurs.

This paper describes the shape optimization of rotor blade in a transonic axial compressor rotor. Three surrogate models, Kriging, radial basis neural network and response surface methods, are introduced to find optimum blade shape and to compare the characteristics of object function at each optimal design condition. Blade sweep, lean and skew are considered as design variables and adiabatic efficiency is selected as an objective function. Throughout the shape optimization of the compressor rotor, the predicted adiabatic efficiency has almost same value for three surrogate models. Among the three design variables, a blade sweep is the most sensitive on the object function. It is noted that the blade swept to backward and skewed to the blade pressure side is more effective to increase the adiabatic efficiency in the axial compressor Flow characteristics of an optimum blade are also compared with the results of reference blade.

The advance of wireless telecommunication and observation technologies leads developing sensor and sensor network for serving the context information continuously. Besides, in order to understand and cope with the context awareness based on the sensor network, it is becoming important issue to deal with plentiful data transmitted from various sensors. Therefore, we propose a context awareness system to deal with the plentiful sensor data in a vast area such as the prevention of a forest fire, the warning system for detecting environmental pollution, and the analysis of the traffic information, etc. The proposed system consists of the context acquisition to collect and store various sensor data, the knowledge base to keep context information and context log, the rule manager to process context information depending on user defined rules, and the situation information manager to analysis and recognize the context, etc. The proposed system is implemented for managing renewable energy data management transmitted from a large scale area.
