The purpose of this research was to evaluate retention of cognitive knowledge, psychomotor skills and self-confidence on CPR 3 months after CPR training program. The sample consisted of 39 nursing students. We provided one rescuer CPR training program for nursing college students on the basis of AHA. The questionnaires for knowledge of CPR were developed 50 items based on AHA guidelines. Self-confidence were checked by 11 items questionnaires. The accuracy of CPR skills were checked by Skillreporter CPR training manikin and by researcher's evaluation based on CPR skill checklist. The results were as follows ; 1. The majority of participants didn't have any previously experiences of CPR training (76.9%). Only 15.1% previously took the CPR training with CPR practice. 2. In terms of self-confidence of CPR. The score were increased for 2 days (p>.001) but retention of self confidence was significantly statistical decreased in 3 months after training (p<.001). 3. There was a statistically significant decrement in mean of knowledge of CPR between 2 days and 3 months after CPR training (p<.001). 4. There was a statistically significant decrement in cognitive knowledge of CPR based on CPR skills checklist(p<.001). 5. Retention scores of psychomotor skills of CPR 3 months after training were 42.10% in numbers of adequate ventilation, 52.81% in numbers of adequate chest compression (p<.001) respectively. 6. Retention of passing rate on chest compressions of CPR 3 months after training was 27% (p<.001), on ventilation was 2.63% (p>.001). The error items with statistically significant differences 3 months after CPR training were too little ventilation (74.36%) and too little chest compressions (92.31%). The results of the study suggest that we need further evaluation of course components which could improve retention of CPR for all trainees.

CPR 시험말뚝에 대해 인발재하시험을 실시하고, 하중-변위 곡선과 하중-침하량 곡선을 분석한 후 항복하중과 허용지지력을 산정하여 주면마찰력을 평가하였다. 하중-변위 곡선으로부터 분석된 CPR 시험말뚝의 결과에 의하면, CPR 시험말뚝의 직경이 큰 경우의 항복하중과 허용지지력이 작은 경우보다 약 1.4배 이상 크게 나타났다. 하중-침하량 곡선으로 부터 분석된 결과에 의하면, CPR 시험말뚝의 직경 D500의 허용지지력이 D400보다 약 1.2~2.1배 큰 것으로 나타났다. 하지만, Fuller 분석에 의해 산정된 허용지지력은 P-S 곡선과 log P - log S 곡선에 의해 산정된 허용지지력과 큰 차이를 보여, Fuller 분석에 의한 허용지지력 산정은 적절하지 않은 것으로 판단되었다.

Purpose: Bystander cardiopulmonary resuscitation (CPR) improves survival. However, there have been few studies on the performance of bystander CPR in Korea. This study was done to identify the reasons for being unwilling to perform CPR, and to investigate the factors associated with performing CPR on a stranger in an emergency situation. Method: The participants in this study were 444 local residents. Data were collected by using self-reported questionnaires from May 1 to June 30, 2010. For data analysis, descriptive statistics and multiple logistic regression were performed using SAS version 9.1. Result: Only 32.2% of respondents reported being willing to perform CPR on a stranger. The major reason for not being willing to perform CPR on a stranger was "have no confidence to perform CPR well". From multiple logistic regression analysis, statistically significant predictors of CPR performance on a stranger were found to be a higher educational level (OR=6.11, 95% CI 1.46-25.52), neighbors with angina pectoris or myocardial infarction (OR=6.65, 95% CI 3.93-11.24), and having confidence of performing CPR (OR=3.02, 95% CI1.78-5.14). Conclusion: CPR education (including automatic external defibrillator) should be offered to family members and neighbors. In addition, the Good Samaritan Law must be given wider publicity at the national level.

Purpose: The purpose of this study was to identify the factors influencing hospital staffs' performance ability of Cardiopulmonary resuscitation (CPR). Methods: The study was conducted with 250 hospital staffs in B hospital located in Busan. The survey data were collected from August 1 to September 15, 2012 and were analyzed using frequencies, percentages, means, t-test, ANOVA, Pearson correlation coefficient and stepwise multiple regression with the SPSS WIN 19.0 program. Results: There were statistically significant differences in performance ability of CPR depending on occupations, CPR experience, CPR situations, identification of Automated external defibrillator (AED) location within the hospital, AED use experience, CPR training experience and AED training experience. A significant positive correlation was found between CPR knowledge and performance ability in addition to a significant positive correlation between CPR attitude and to performance ability. The significant factors influencing performance ability of CPR were CPR attitude, occupations, CPR training experience, knowledge and identification of AED location within the hospital. Those factors explained about 40.1% of the variance. Conclusion: It is necessary to develop a strategy for hospital staff to improve the levels of performance ability of CPR.

Purpose: This study is a non-equivalent control group pre-post design, which attempted to observe the effects of Basic Life Support Education on undergraduate students' CPR Knowledge and Attitude. Methods: The subjects were 96 undergraduates in Jeonbuk. They were divided into two groups: an experimental group of 46 students and a control group of 50 students. The BLS education was given by three BLS instructors certified by the American Heart Association using a DVD. Data were collected from October 20 to November 15, 2010 and analyzed, using the ${\chi}^2$ test, t-test, and ANCOVA. Results: There were significant differences between the experimental group and the control group in the levels of CPR Knowledge and Attitude. The 1st hypothesis, that the CPR knowledge scores for the experimental group would be higher than those of the control group, was supported (F=157.58, p=.000). The 2nd hypothesis, that the CPR attitude scores for the experimental group would be higher than those of the control group, was supported (F=23.78, p=.000). Conclusion: This study showed that BLS education had a positive influence on undergraduate students' knowledge and attitudes toward CPR. We expect that BLS education will contribute to spreading knowledge of CPR and reducing mortality among heart attack victims, and we can see from this study how CPR training in combination with theory and clinical practice develops knowledge and practical ability.

In order to understand the functional role of CPRl in Saccharomyces cerevisiae KNU5377 with regard to its multi-tolerance characteristics against high temperatures, inorganic acids, and oxidative stress conditions, whole cellular proteins were analyzed via liquid chromatography electrospray ionization tandem mass spectrometry (LC-ESI-MS/MS). This procedure was followed by two-dimensional (2-D) gel electrophoresis. Under menadione stress conditions, the 23 upregulated proteins were clearly identified only in the wild- type strain of KNU5377. Among the proteins, Sodl1p Tsa1p, Ahp1, Cpr1p, Cpr3, Ssb2p, and Hsp12p were identified as components of antioxidant systems or protein-folding related systems. The CPR1 protein could not be completely detected in the $cpr1{\Delta}$ mutant of KNU5377 and the other upregulated proteins in the wild-type strain evidenced a clear correlation with the results of immunoblot analysis. Moreover, a reduction in growth patterns (about 50%) could be observed in the $cpr1{\Delta}$ mutant, as compared with that of the wild-type strain under mild MD stress conditions. These results indicate that the upregulation of CPR1 may contribute to tolerance against MD as an inducer of oxidative stress.

Purpose: This study aimed to compare the chest compression quality between compression-only cardiopulmonary resuscitation (CPR) and conventional CPR. Methods: This study involved 123 participants randomly assigned to either the chest compression-only CPR training and conventional CPR training. After training for 120 min, the participants performed CPR for 4 min and the CPR quality was evaluated. The primary outcome was evaluated as the mean compression depth, and the secondary outcome was calculated as the proportion of chest compressions with an appropriate depth among the total chest compressions. Results: The mean compression depth was more deeper in conventional CPR than in compression-only CPR (57mm vs. 53mm, p <.001). The proportion of appropriate chest compression depth was also more higher in conventional CPR (98.8% vs. 68.6%, p <.001). As compared with every minute over time for a total of 4 min, the mean compression depth and the proportion of appropriate chest compression depth were deeper and higher after 1 min in conventional CPR than in compression-only CPR. Conclusion: The results suggested that conventional CPR is a better method than compression-only CPR in terms of chest compression quality.
