BLS adjustment methods have been able to provide more accurate estimates of total and make samples represent population characteristics by post-adjustment of design weights of samples. However, BLS methods use additional data, for instance number of employee, without this information or using other information, give different weight adjustment factors. In this paper we studied the sensitivity of the variables used in BLS adjustment. The 2007 monthly labor survey data is used in analysis.

Purpose. The purpose of this study was to explore the meaning of BLS-Provider Certification Course experienced by nursing students. Methods. The phenomenological method developed by Giorgi was used for this study. The participants were 7 students who had experienced BLS-Provider Certification Course. The data were collected between February, 2013 and May, 2013 by face to face interview. The interview was recorded and then transcribed. Results. The constituents associated with the meaning of the Nursing students's experiences on BLS-Provider Certification Course were as followings 'To obtain the information', 'Complicated preparation process', 'Unfamiliar education', 'Fear on the BLS ', 'Satisfaction after getting of BLS-Provider Certification ' Conclusions. The result of this study may contribute to a deeper understanding of the meaning of the BLS-Provider Certification Course experienced by nursing students. The highlights of this study are that, although the students had much inconvenience on the preparation process of BLS-P and fear on the BLS-Provider Certification Course, they were satisfied much after getting the BLS-Provider Certificate. It can give the better quality of BLS-Provider Certification Course if these results are provided in the program.

Efficiency and sensitivity of BLS adjustment method have been studied and the method is known to provide more accurate estimate of total by using properly adjusted weights of samples. However, BLS methods provide different efficiencies according to the magnitudes of correlation coefficients and the sizes of samples in strata. In this paper we study the efficiency of the BLS adjustment according to the sample sizes and correlations in strata. For this study, 2007 monthly labor survey data is used.

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.

BLS weight adjustment is a widely used method for business surveys with non-responses and outliers. Recent surveys show that the non-response weight adjustment of the BLS method is the same as the ratio imputation method. In this paper, we suggested a modified BLS weight adjustment method by imputing missing values instead of using weight adjustment for non-response. Monthly labor survey data is used for a small Monte-Carlo simulation and we conclude that the suggested method is superior to the original BLS weight adjustment method.

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.

The purpose of the study is to investigate the effect of a simulation training of BLS in paramedics in pre-hospital situation. This a nonequivalence control quasi-experimental study. The study subjects were 8 paramedics of experimental group and 8 paramedics of control group in K fire department. An informed consent was written by the subjects after explaining of the purpose of the study. The study methods consisted of conventional education and practice training. The conventional education was done for 30 minutes and the practice training was taken by four trainees of one group and the instructor demonstrated Basic Iife Support (BLS) performance for three minutes. Each trainer peformed BLS for ten minutes. In the beginning of the course, two paramedics got off from the ambulance and performed BLS including 5 cycles of Cardiopulmonary Resuscitation (CPR). Soon after the BLS, another two paramedics performed pre-hospital BLS survey. The education was guided by two professors of emergency medical technology, two Basic Iife Support instructors, and two emergency rescue directors. Pre-hospital BLS was measured by a 5-point Likert scale. Higher score means higher performance skills. The data were analyzed using SPSS/WIN 22.0 program set at significance level of p<05. The effect of simulation education was much more significant than the conventional education in BLS. The simulation education is very important and effective in improving the clinical performance skills of paramedics than the conventional education. The simulation education can provide the virtual environment of cardiac arrest to the paramedics. In conclusion, the simulation education can provide the effective teaching methods for various practice performance skills and solution by critical thinking in the paramedics and healthcare providers in the future.

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.

Cross-wave regression imputation and carry-over imputation method are generally used in the analysis of panel data with missing values. Recently it is known that the BLS non-response adjust method has good statistical properties. In this paper we show that the BLS method can be considered as an imputation method with a similar formula of a ratio-estimator. In addition, we show that the carry-over imputation and BLS imputation are approximately the same under the assumption that data follow a non-stationary process with drift. Small simulation studies and real data analysis are performed. For the real data analysis, a monthly labor statistic (2007) is used.
