Purpose : The purpose of the study is to investigate the quality and relevance of back strength or chest compression which is applied by isotonic exercise of hip joint. Methods : Subjects were 37 students who participated in the BLS course and accepted the informed consent from December 7 to 8, 2012. During CPR performance, back strength was measured by the researcher. CPR was used the manikin for practical training with using PC, conducted by standard CPR for 2 minutes, Quality of chest compressions included average chest compression depth, rate, and recoil ratio. Results : Back strength (kg) is related to the chest compression depth (mm) (r =.746, p <.001). The high quality CPR is the most important factor so high quality is full chest recoil of chest compression and chest compression depth (mm) (${\beta}$=.831, p <.001). In this study, chest compression rate and recoil ration were not influenced by back muscle strength. Conclusion : It is necessary to implement the CPR program to improve physical strength and effective performance of CPR.

Purpose : This study set out to compare the educational effects of a video self-instruction program for child CPR education on childcare teachers by applying the 2006 KACPR Guideline. By adopting the nonequivalent control group posttest quasi-experimental design, the study examined the educational effects on a group that did not receive instructions from the instructor, another group that received his instructions, and the other group that received an extra three-minute practice training session in addition to instructions. Methods : Data were gathered from August 6 to 18, 2008. As for research tools, the Knowledge Instrument of CPR by Connolly (2006) was used along with the National Practice Test Protocol for C1ass 1 Emergency Medical Technicians (2007) and Common Protocol for CPR (2006) to examine the performance of child CPR. By shooting the guide screen of $Resusci^{(R)}$ Junior CPR Manikin of Leardal with a video camera and using the Skill Guide Checklist of the Common Protocol for CPR (2006), the subjects' technical accuracy of chi1d CPR was evaluated. There were three subject groups: 29 childcare teachers randomly assigned to received the video self-instruction program training for chi1d CPR and no instructions from the instructor made up the control group; 22 childcare teachers randomly assigned to received the program training and instructions from the instructor made up experiment group I; 23 childcare teachers randomly assigned to received an extra three-minute practice training session in addition to the program training and the instructions made up experiment group II. The gathered data were analyzed with SPSS/PC+ (Version 14.0) in frequency, percentage, $X^2$-test, ANOVA, Scheffe test. Results : 1) There were no statistically significant differences (F=1.030, p=.362) among the groups in terms of knowledge scores after the child CPR education. 2) There were statistically significant differences (F=13.625, p=.000) among the groups in terms of performance abilities after the child CPR education. 3) There were no statistically significant differences (F=1.610, p=.207) among the groups in terms of technical accuracy of mouth-to-mouth resuscitation after the child CPR education 4) There were no statistically significant differences (F=1.484, p=.234) among the groups in terms of technical accuracy of chest compression after the child CPR education. Conclusion : The results indicate that childcare teachers can improve their performance abilities in child CPR when the instructors are active with their instructions and extra practice hours are secured through a VSI program. It's also needed to provide education with increasing concentration ratio about the items of lower knowledge points in order to help the teachers learn the accurate theory of child CPR. And there should be VSI programs of diverse conditions to increase the effects of child CPR training among childcare teachers.

The purpose of this study was to evaluate effects of mobile web-based cardiopulmonary resuscitation(CPR) convergence education for nurses. This study used a nonequivalent control group pretest-posttest design. A sample of 46 nurses was included. The experimental group was given mobile web-based online CPR education with self-directed offline CPR practice. The control group was given traditional CPR lecture education with CPR practice. The data were collected using a structured questionnaire and performance skill test and were analyzed using SPSS 21.0 program. The experimental group had higher scores on CPR knowledge and CPR self-efficacy than those of the control group. there were no significant differences between groups (p=.741; p=.162). CPR skill ability was significantly higher in the experimental group compared to the control group(p=.001). This findings indicate that mobile web-based CPR convergence education can be an effective to strengthen CPR capabilities for nurses. These contribute to expanding convergence of education program development.

The purpose of this study was to provide basic data for the improvement of the guidelines and training programs regarding the cardiopulmonary resuscitation performance of bystanders who can respond to the incidents in earlier times as the first responder of the cardiac arrest incident, by reviewing the performance of basic CPR and the influencing factors after providing 70 students of Department of Emergency Medical Technology with the CPR training. For the purpose of the study, the collected data were computerized and analyzed by SPSS-WIN program(ver. 10.1). The results for this study were as follows The duration of session between the groups in the BLS CPR were 3 minutes and 36 seconds, 2 minutes and 32 seconds respectively. The average compression number per minute were 24.3 times and 33,2 times respectively(p=.000), and the average compression rate per minute were 112 times and 122 times respectively(p=.000). The average ventilation number per minute were 3.54 times and 5.1 times respectively(p=.000). The errors in compression "Too shallow" were 20.73 times(34.6%) and 23,23 times(38,7%) out of 60 times in 4 cycles with the standard of 38 nun. In CPR performance results according to gender in the first episode, males showed better results in compression depth as 41.5 mm comparing to females average 38.2 mm(p=.015). When ventilation results were compared according to the use of FS, the average ventilation number per minute, total ventilation per minute and the average volume per episode were significantly higher when FS was not used(<.040), There was no significant difference in ventilation accuracy between two groups. According to the results, we need to improve and distribute portable barrier devices, and to be familiar with those devices. We need to enforce ventilations as well as to include compressions so that faster and more accurate CPR can be performed. Additionally, we need to exclude ventilation only cases, minimize the interference time of chest compression due to inaccurate ventilation, simplify or minimize the complicatedness of CPR performance and responding time related to breathing, provide first responders with various training programs such as initial assessment and ventilations only, or initial assessment and chest compression-only CPR and than provide advanced training with AHA BLS education including CPR for more than two people according to CPR skills and target characteristics.

Purpose: The performance rate to perform Cardiopulmonary Resuscitation (CPR) by witness in out-of-hospital Cardiac Arrest (OHCA) is very low in South Korea. To prevent the death caused by OHCA, it is important to encourage the witness to perform CPR actively. The purpose of the study is to investigate the influencing factors to affect bystander CPR rate. Methods: I conducted a questionnaire survey from 25 February to 4 March, 2013, receiving responses from 517 people in Korea. The questionnaire included social demographic factors, history of heart disease, knowledge of CPR, and the reliability of emergency medical service (EMS). A logistic regression analysis was conducted. Results: Among the 517 respondents, 294 (57.4%) had intention of performing CPR. Multiple logistic regression analysis found the following significant predictors of CPR intention: gender (odds ratio [OR] = 0.390), age (OR = 1.024), religion (OR = 0.843), and knowledge of CPR (OR = 4.734). Conclusion: This study indicated that the strongest predictor is knowledge of CPR. Therefore, it would be helpful to teach CPR nationwide to encourage performing CPR. In addition, effect of CPR education in religious facilities is necessary.

In Korea, there are around 30,000 cardiac arrest patients annually. Gradually the number is increasing. Against this background, CPR education and publicity programs were expanded nationwide, but the rate of witness CPR by the general public was 4.4%, which is significantly lower than the 20%~70% rate in other countries. Therefore, in this paper, we analyzed the factors affecting the performance of CPR by witnesses who discovered cardiac arrest patients. Based on the results, an application planning and development study was conducted to provide users with correct cardiorespiratory response tips and step-by-step CPR guidelines to help users effectively assist in increasing the rate of CPR by general eyewitnesses.

This study was carried out as a descriptive correlation study to identify the knowledge and performance of CPR of nursing students who have experience in CPR education and to explore the relationship between them. Participants in this study were 204 nursing college students who were enrolled in the 4th year of nursing at two universities located in G Metropolitan City from October 18 to October 30, 2018. For the collected data, IBM SPSS Win 21.0 version Program was used. The correlation between the subject's CPR knowledge and performance was evaluated using the Pearson Correlation Coefficient. There was a positive correlation between CPR knowledge and CPR performance (r=.22, p=.01), and it was found that the higher the CPR knowledge, the higher the CPR performance. Since this study is convenient extraction of nursing students from two universities in G Metropolitan City, there may be limitations in generalizing the results of this study. It is a self-reported indirect measurement rather than a direct measurement that measures by observing, reflecting the subject's subjectivity, and there is a concern that the effect of education may not be measured objectively. Therefore, further research using a direct measurement tool of CPR performance is needed.

Purpose: This study aimed to develop a cardiopulmonary resuscitation training program for firefighters (FD-CPR) to help improve the survival rate after cardiac arrest on the fireground. Methods: The FD-CPR was developed following 3 steps of the FD-CPR instructional design based on the behaviorism theory. The content of the program was validated by a group of 7 experts using the contents validity index (CVI) and through a pilot-test. Results: A scenario consisting of 7 procedures, and a skill performance evaluation tool consisting of 16 questions were developed. The evaluation tool average score for the difficulty test was 41.16% (even) and that for the discrimination test was 0.32 (high). Subsequently, an 80 min training program was developed. As verified by the 7 experts through the CVI, it was as high as 1.0. Conclusion: The FD-CPR developed domestically for the first time in this study was effective in enhancing the CPR performance skills of the firefighters. If FD-CPR is added to the curriculum at the Fire Service Academy educational course for the new firefighters, the CPR performance skills could be maintained. Furthermore, the program can facilitate a better survival rate for colleagues having cardiac arrest on the field.

Purpose: To determine factors of kindergarten teachers' willingness to perform cardiopulmonary resuscitation (CPR) and to suggest education methods toward CPR. Methods: We interviewed 92 kindergarten teachers trained to administer CPR. Among them, 74 answered the questions regarding CPR experience, barriers, and willingness. Logistic regression was used to calculate odds ratios (OR) and 95% confidence intervals (CIs) for the association of willingness factors to cognition, performance, and attitude toward CPR. Results: Of the participants, 73 (98.7%) were female, 32 (43.0%) were in their twenties (mean age: 33.9 years), 31 (41.9%) graduated college, 47 (63.5%) had < 10 years of tenure, and 65 (87.8%) and 62 (83.8%) indicated willingness to perform CPR to family members and kindergarteners, respectively. Barrier factors included fear of performing CPR incorrectly (46.8%) and injuring the victim (25.6%). Willingness factors included understanding brain death (37.7%) and performing CPR correctly (26.1%). Willingness predictors included attitude toward family members (OR: 4.54, 95% CI: 1.19 -17.39, p = .027) and kindergarteners (OR: 3.07, 95% CI: 1.15-8.22, p = .025), and cognition to kindergarteners (OR: 0.36, 95% CI: 0.13-0.99, p = .050). Conclusion: The kindergarten teachers were more willing to perform CPR to family members and kindergarteners than to others in an attitude-dependent manner.
