This research, by analyzing the current first aid education status in K district, Seoul and comparing first aid education systems in other developed countries, introduces the need of first aid/Cardio Pulmonary Resuscitation(CPR) education with Automated External Defibrillator(AED) usage to high school students, who are on the verge of becoming adults. The thorough research shows that schoolsshould be appointed as mandatory facilities for AEDs by laws and execute first aid education to their students. Only through organized and consistent first aid education would the students develop into true volunteers who not only have altruistic minds, but the ability to fluently adapt to medical emergency and properly use AED. In addition, the research also outlines various laws that could be legislated such as having to master the basic degrees of first aid education before getting driver's license and graduating high school so that more people become aware of first aid.

Purpose: This study measured awareness of automated external defibrillators (AED) among students majoring in health-related versus non-health-related fields. Methods: A total of 577 students filled out a questionnaire on awareness of AEDs between June 12 and June 28, 2017. Using SPSS 23.0, data were analyzed using descriptive statistics, chi-square tests, and t-tests. Results: In response to a question about awareness of AED, 25.0% of students majoring in a health-related and 38.6% of those majoring in a non-health-related field answered on "I have seen or heard" and "I have no idea". In response to a question on perception on AED use, 82.4% of students majoring in a health-related field and 88.1% of those in a non-health-related field reported that they thought perception of AED use was not universal. In terms of experience with education on the use of AED, 30.2% of health-related majors and 49.7% of non-health-related majors had not received any training on the use of AED. The average overall score regarding knowledge about AED was 8.69 for health-related majors, compared to 7.79 for non-health-related majors. Conclusion: In order to improve awareness regarding AED use, education on importance and necessity of AED should be emphasized and implemented consistently by the mass media.

Virtual reality technology was initially developed for entertainment purposes such as games, movies, sports, and theme parks, but gradually expanded to a number of industries such as education, e-commerce, and health care,. Therefore, safety education content incorporating VR is also rising rapidly. However, the program activity on safety education in our country is still insignificant. Although rescue of patients with acute cardiac arrest using defibrillators is one of the most representative safety education, in 2014, defibrillators are rarely used in Korea to save the lives of patients and there are very few cases of using defibrillators. The use of automatic defibrillators and the importance of knowing how to use them for expanding accessibility are necessary. However, it is not easy to provide experience education only after completing the safety education in simple theoretical education. In this paper, we propose a automatic defibrillator training simulation system using virtual reality that can be freelu trained at any time.

This study examined the level of knowledge, attitude, and performance ability of automated external defibrillator (AED) and cardiopulmonary resuscitation (CPR) among university students who were not in health-related majors and to explore the relationships among these variables. In this study, 291 students were recruited from 3 universities in D city. Among them, 77.0% had ever seen or heard of AED and 61.9% did not know how to use it. The levels of knowledge, attitudes and performance ability differed significantly according to the CPR training experience and AED awareness (p<.002~.001). The performance ability showed significant correlations with knowledge (r=. 42, p<.001) and attitude (r=. 55, p<.001) of AED and CPR. These findings suggest that future AED and CPR training programs should be developed to promote a positive attitude towards the willingness to perform AED and CPR as well as to increase the participants' confidence by repeated training.

The AED (Automated External Defibrillator) is not evaluated for spatial accuracy and temporal availability even if it is located within a building or a specific area that needed necessary to partition by spatial analysis and location allocation analysis. As a result of the analysis, the spatial analysis was performed using the existing public data of AED with applied the GIS location analysis method. A public institution (119 safety center, police box) was selected as a candidate for a public AED base that can operate 24 hours a day, 365 days a year according to the characteristics of each residential area. In addition, Thiessen Polygons were created for each candidate site and divided by regions. In the analysis of the service was analyzed regional in terms of accessibility to emergency medical services in consideration of the characteristics of AED, that emergency vehicles could arrive within 4 minutes of the time required for emergency medical treatment in most areas of the study area, but it did not areas outside of the city center. As a result, It was found that the operation of the AED base service center centered on vehicles of public institutions is effective for responding to AED patients at night and weekend hours. 19 Safety Center under and police box the jurisdiction of Daegu City to establish an AED service center for public institutions, location-based distance, attribute analysis, and minimization of overlapping areas that the method of using a vehicle appeared more efficient than using the existing walking type AED.

This study proposes an algorithm for removal of CPR artifact in order that automated external defibrillator (AED) can effectively diagnose ECG rhythm during cardiopulmonary resuscitation (CPR). Current AED required to interrupt chest compression for reliable rhythm analysis to avoid the effect of artifacts produced by CPR. However even temporarily interruption of chest compression during CPR adversely affects the probability of restoration of spontaneous circulation (ROSC) and survival after the delivery of the shock. Therefore, we proposed a method for removal of CPR artifacts using least mean square (LMS) filter. The removal of the CPR artifacts would enable compressions to continue during AED rhythm analysis, thereby increasing the likelihood of resuscitation success. It was tested on 31 segments of shockable and 300 segments of non-shockable ECG signals recorded from three pigs during CPR. In the result, sensitivity (Se) and specificity (Sp) analysis on the test segments showed values of Se = 3.2%, Sp = 66.0% and Se = 96.8%, Sp = 98.7% in the case of unfiltered and filtered signals during CPR. In conclusion, it was shown that the proposed method can be a useful tool to exactly diagnose the ECG rhythm during the CPR.

The number of patients with cardiovascular diseases who experience an out-of-hospital cardiac arrest (OHCA) are increasing among young adults as well as the aged population. An automated external defibrillator (AED) is vital in improving survival rates of OHCA victims. Survival rates of OHCA were shown to decline exponentially in time to defibrillation, yet studies in Korea are uncommon that captures the properties of their survival rates in examining optimal locations of AEDs. In this study, we worked on the maximal gradual coverage location problem (MGCLP) with exponential decay coverage function to decide on their optimal locations. The exponential decay coverage function mitigates the drawback of over-estimating survival rates of OHCA patients. It is expected that a more sophisticated facility location problem will be developed to identify the "emergent" characteristics of pedestrians who responds to the OHCA occurrence by incorporating random pedestrian locations and movement through simulation.

Objective: The increasing number of people living in high-rise apartments may result in a delayed response from emergency medical technicians called out for an out-of-hospital cardiac arrest, making the role of apartment managers as the first responders extremely important. This study investigated whether automated external defibrillator (AED) placement influences the willingness of apartment managers to perform cardiopulmonary resuscitation (CPR) and use an AED. Methods: A cross-sectional target population-based survey was conducted in Daegu, July 2016. Questionnaires were sent to apartment managers working in apartments with more than 500 households. The general characteristics of the respondents, status of CPR education, and knowledge about and willingness to perform CPR and use an AED were investigated. Results: Of the 1,445 respondents, 758 (52.5%) worked in apartments with AEDs, of which 77.8% and 70.8% were willing to perform CPR and use an AED, respectively, compared with 68.1% and 60.0% of respondents who worked in apartments without AEDs. After adjusting for potential confounders, AED placement was associated with the willingness to perform CPR (odds ratio [OR], 1.33; 95% confidence interval [CI], 1.04-1.71) and use an AED (OR, 1.39; 95% CI, 1.10-1.75). Prior CPR training and accurate knowledge of CPR skills were also associated with the willingness to perform CPR and use an AED. Conclusion: Placing AEDs in high-rise apartment buildings and providing refresher CPR education for maintaining CPR skills will be necessary to support apartment managers in their role as first responders.
