미국 노동통계청에서 사용하고 있는 BLS 방법의 효율성과 민감성에 관한 연구 결과에 의하면 표본 틀 (Sample frame) 자료와 조사된 자료의 상관관계가 높을수록 BLS 무응답 보정 효과는 커지는 것으로 알려져 있다 (이석진과 신기일, 2008). 그러나 표본 틀 자료와 조사된 자료의 상관계수가 층별로 크기가 다른 경우, BLS 보정 효과는 달라질 수 있다. 따라서 일반적으로 실시되는 표본 설계에서는 층화추출 방법이 사용되기 때문에 각 층의 표본 크기와 상관계수가 다른 경우의 BLS 보정 효과률 살펴보는 것은 매우 중요하다. 본 논문에서는 층의 표본 크기와 상관계수 그리고 무응답 비율에 따른 BLS 무응답 보정 효과를 살펴보았다. 이를 위해 사용된 자료는 노동부의 월별 자료인 2007년 매월노동통계 자료이다.

Purpose: This study was performed to investigate the level of knowledge, self-confidence, and intention of basic life support (BLS) and identify the reason why clinical nurses lack confidence to initiate BLS at the cardiac arrest scene. Method: A cross-sectional survey was used with questionnaires which authors developed; a BLS knowledge questionnaire and a tool for measuring the level of self-confidence and intention of performing BLS. The subjects consisted of 396 nurses by convenient sampling from ten small to medium sized hospitals in Korea. Data were collected from March to August, 2008. Data were analyzed by the SPSS/WIN 14.0 program with t-test, ANOVA, and Pearson correlation coefficients. Results: The percentile score of BLS knowledge was 40.6%, self-confidence 62.1%, and intention 73.0%. Clinical career rather than BLS knowledge has a significant effect on increasing the self-confidence and intention of performing BLS. A major reason for not performing BLS was lack of confidence in operating an AED (automatic external defibrillator). Conclusion: An effective and continuous training program especially including AED for CPR should be provided with clinical nurses to increase self-confidence and intention of performing BLS and to improve the survival of cardiac arrest patients in the hospital.

Purpose: This study was done to examine the effects and retention of the American Heart Association (AHA)'s basic cardiac life support (BLS) training on knowledge and skills of nursing college students. Method: The study was a one group pretest-posttest experimental design. The sample included 41 junior nursing students from D college who participated in an AHA BLS course for healthcare providers in K hospital from January 18 to June 7, 2010. The instruction was based on ‘BLS knowledge and skills'. The data were analyzed with paired t-test using the SPSS/PC 12.0 win. Result: First, knowledge (t=-7.648, p=.000) and skills (t=-12.988, p=.000) were significantly increased immediately after BLS training. Second, knowledge (t=4.098, p=.000) and skills (t=50.350, p=.000) of BLS after 4 months was significantly decreased compared to right after BLS training. Conclusion: Knowledge and skills were decreased 4 months after BLS training. Therefore, retraining in BLS is required within 4 months. To maintain the knowledge and skills of BLS, appropriate renewal time and retraining programs are needed.

Purpose : The purpose of this study was to investigate the effectiveness of cardiopulmonary resuscitation (CPR) and automated external defibrillator (AED) education for school teachers by questionnaire survey including the knowledge, self-efficacy and skills of CPR and AED after basic life support (BLS) education. Methods : The subjects were school teachers who participated in BLS education from 24 Nov. to 1 Dec. 2012. They completed the self-reported questionnaire based on BLS skill checklist. Results : There was a statistically significant increase in the knowledge(p <.001), self-efficacy (p <.001) and skills(p <.001) of CPR and AED after BLS education. The correlation existed conspicuously between knowledge versus self-efficacy(r =.409, r =.387), knowledge versus skill(r =.442, r =.084), and self-efficacy versus skills (r =-.148, r =.047) of CPR and AED before and after BLS education. Conclusion : After BLS education, most of the participants found the program was easy and useful to perform. Participants had the willingness to do CPR and AED and wanted to teach BLS to others. It is necessary to provide BLS education for school teachers by systematic approach.

Purpose: The purpose of this study was to evaluate the effects of BLS training in nursing students and their retention period. Methods: The participants were 48 nursing students enrolled in M University in Mokpo. Data were collected from September, 2009 through September 2010. Nursing students were tested for their knowledge, attitude, confidence before, immediately after, 4 weeks after, 8 weeks after, 6 months after, and 1 year after BLS training. In addition, their knowledge and skill of cardiopulmonary resuscitation were tested 5 times. Data were analyzed using the SPSS/PC 12.0 statistical program Results: Knowledge, attitude and confidence were significantly increased immediately after compared to before BLS training. Knowledge and confidence 6 months after, and attitude, performance ability and technical precision for ventilation and compression 4 weeks after BLS training were significantly decreased compared to immediately after. Conclusion: Overall retention of BLS training effects among nursing students, without reinforcement, decreases significantly after six months following initial training. BLS training in nursing students should be repeated every six months, especially performance training of BLS should be repeated every 4 weeks. In addition, to maintain the knowledge and skills of BLS, appropriate renewal time of certification and improvement of training programs are necessary.

Purpose: In order to elucidate the effects of BLS (Basic Life Support) education for primary students, we analyzed data collected using a questionnaire on attitude toward CPR. Methods: Students were divided into two groups, the experimental group with BLS education and the control group without BLS education. Data was collected after BLS education for the experimental group. While they were learning BLS, the control group completed the questionnaire. Results: There were significant statistical differences in the total score of students' attitudes. The students in the experimental group indicated a more positive attitude toward CPR than the others. Conclusion: This study showed that BLS education had a positive influence on elementary students' attitudes toward CPR. We expect that the result will contribute to the spread of CPR and the reduction of mortality.

Objectives: The aim of the study was to investigate the attitude and influencing factors toward basic life support in the dental hygienists. Methods: A self-reported questionnaire was completed by 218 dental hygienists in Gwangju. The questionnaire consisted of the general characteristics of the subjects and attitude toward basic life support (BLS). The attitude included cognitive belief, behavioral components, and emotional components. The data were analyzed by independent t-test, one-way ANOVA and multiple regression analysis by using IBM SPSS 21.0 program. Results: The cognitive belief, behavioral component, and emotional components of attitude toward BLS had higher scores in those who were between 34-34 years old and had more than 10 years of career. Most of them worked in dental clinic and did not earn the BLS certificate. There were positive correlations between the cognitive belief, behavioral components, and emotional components toward BLS. By the regression analysis, cognitive belief toward BLS was positively associated with educational experience within a year, behavioral components, and emotional components. The behavioral components were associated with working between 5-10 years in dental clinic and the emotional components. Conclusions: The attitude toward BLS in the dental hygienists was low in cognitive belief, behavioral components, and emotional components. Therefore, BLS education must be expanded to the dental hygienists.
