Purpose: Meta-analysis of this study was to analyze the character of adolescent smoking cessation programs, to calculate the effect size according to variables and to compare the weighted mean effect sizes on adolescent smoking cessation programs in Korea. Methods: Twenty two studies for meta-analysis were selected from dissertations, theses, articles and research papers that had been published from 1995 to 2003. The selected studies had a randomized or nonequivalent control group in a pretest-post test design and had reported statistical value to calculate the effect size. Results: The mean number of sessions was 6.5. The education time per each session varied from 40 to 150 min and the most applied theories were Bandura's social-cognitive theory and the cognitive-behavioral theory. Smoking-knowledge, smoking-attitudes and smoking-amount showed high effects on the first post test after mediating adolescent smoking cessation programs according to the criteria of Cohen. The effect size of urine-cotinine found no homogeneity on the first post test, but it was significantly effective on the second post test. Conclusion: Adolescent smoking cessation programs analyzed in this study were relatively effective in smoking abstinence.

Background: We aimed to comprehensively review the evidence for using sputum DNA to detect non-small cell lung cancer (NSCLC). Materials and Methods: We searched PubMed, Science Direct, Web of Science, Chinese Biological Medicine (CBM), Chinese National Knowledge Infrastructure (CNKI), Wanfang, Vip Databases and Google Scholar from 2003 to 2013. The meta-analysis was carried out using a random-effect model with sensitivity, specificity, diagnostic odd ratios (DOR), summary receiver operating characteristic curves (ROC curves), area under the curve (AUC), and 95% confidence intervals (CI) as effect measurements. Results: There were twenty-two studies meeting the inclusion criteria for the meta-analysis. Combined sensitivity and specificity were 0.62 (95%CI: 0.59-0.65) and 0.73 (95%CI: 0.70-0.75), respectively. The DOR was 10.3 (95%CI: 5.88-18.1) and the AUC was 0.78. Conclusions: The overall accuracy of the test was currently not strong enough for the detection of NSCLC for clinical application. Dscovery and evaluation of additional biomarkers with improved sensitivity and specificity from studies rated high quality deserve further attention.

The purpose of this study is to synthesize research findings on the relationship between parenting efficacy and the variables related to it, as well as to produce results using meta-analysis. The following questions guide this study : Which variables are frequently conducted in research related to parenting efficacy? What is the effect size of each variable? The 65 studies whose results are analyzed in this paper were collected via a search for investigations focusing on 'parenting efficacy'. The studies were used for meta-analysis in which eleven variables were selected. The results of the analysis indicate that a large effect size is produced by the parenting stress in a negative direction. A higher than medium effect size occurs on the basis of parenting beliefs in a negative direction. A higher than medium effect size is also caused by the father's involvement in child care and social support. A medium effect size is produced on the basis of children's temperament, and a small effect size is the result of the mother's academic background, parenting knowledge, and parent's income. There is no relationship between parenting efficacy and children's gender.

Purpose: This study aimed to identify the effects of cardiopulmonary resuscitation (CPR) training using a meta-analysis by effect size. Methods: The effect sizes for each variable and the overall effect size for the collected data were identified. The homogeneity verification of the effect size and the difference among the average effect sizes for each mediation variable were determined. Results: The overall average effect size for CPR training was 1.747. Homogeneity verification of the overall effect size was a Q-value of 3716.962, which was statistically significant (p=.000) when${\alpha}=.05$. CPR training showed statistically significant differences depending on age (p=.002), sex (p=.006), number of trainees (p=.000), research design (p=.000), training method (p=.027), and practical training tools (p=.000). Conclusion: CPR training can effectively improve knowledge, skills, and attitudes about CPR. The results of this meta-analysis contribute to the development of more effective educational guidelines for future CPR training and the advancement of the CPR education field.

Background: Although the erector spinae plane block has been used in various truncal surgical procedures, its clinical benefits in patients undergoing spinal surgery remain controversial. The aim of this meta-analysis was to evaluate the clinical benefits of erector spinae plane block in patients undergoing spinal surgery. Methods: We searched the Cochrane Library, PubMed, EMBASE, and China National Knowledge Infrastructure for randomized controlled trials comparing the erector spinae plane block with a nonblocked control for spinal surgery. Results: Twelve studies encompassing 696 subjects were included in our systematic review and meta-analysis. We found that the erector spinae plane block decreased postoperative pain scores and opioid consumption in the postoperative and intraoperative periods. Moreover, it prolonged the time to the first rescue analgesic, reduced the number of patients who required rescue analgesia, and lowered the incidence of postoperative nausea and vomiting. However, it did not exhibit efficacy in decreasing the incidence of urinary retention and itching or shortening the length of hospital stays, or the time to first ambulation. Conclusions: Erector spinae plane block improves analgesic efficacy among patients undergoing spinal surgery compared with nonblocked controls; however, there is insufficient evidence regarding the benefits of erector spinae plane block for rapid recovery.

Purpose: The purpose of this study was to review and synthesize the existing literature on the experience of nursing students in simulation. Methods: A systematic review was undertaken using meta-ethnography. Eight databases were searched up to January 2014 for peer-reviewed studies, written in Korean and English, that reported primary data, used identifiable and interpretative qualitative methods, and offered a valuable contribution to the synthesis. Results: Nine studies were identified, with quality appraisal undertaken. Three key concepts were generated: ambivalence of simulation practice, learning by reflection, and building up of the competency as a future nurse. Six sub-concepts emerged: double sidedness of simulation setting; feeling ambivalence of simulation; learning from others; learning from self-reflection; improvement of confidence by role experience; and internalization of nursing knowledge. A line of argument has been developed based on the themes generated. Conclusion: The findings from this qualitative synthesis and other related literature indicated the importance of capability of educator and extension of the simulation system to facilitate effective simulation-based education.

프로그래밍 언어 학습이 논리적 사고력에 미치는 영향에 대한 선행 연구는 부족한 실정이며, 각 연구 결과마다 연구 대상, 방법과 학습 주제 등에 따라 논리 향상 정도와 영역이 다르므로, 일반화 과정에 어려움이 있다. 또한 논리적 사고력의 향상이 학습자의 인지 발달에 의한 것인지 프로그래밍 언어 학습에 의한 것인지 분명하지 않아 프로그래밍 언어 학습의 필요성이 증명되었다고 할 수 없다. 본 연구에서는 초등 6학년생들에게 교육용 프로그래밍 언어 학습을 7차시 동안 실시한 후, 메타인지 수준별로 논리적 사고력에 미치는 영향을 조사하고, 컴퓨터 활용 교육의 효과와 비교하였다. 실험 결과에 따르면, 두리틀과 로고, 그리고 파워포인트 학습 집단 모두에서, 상위 수준의 메타인지를 지닌 학생들은 논리적 사고력에 유의미한 신장 효과를 나타낸 반면, 하위 수준의 학생들은 두리틀과 로고 학습 후에만 유의미한 논리적 사고력의 신장을 나타냈다. 그러나 메타인지 수준에 상관 없이 세 학습 집단 간에 논리적 사고력 향상 정도의 유의미한 차이는 없었다.

Objectives: Several preclinical and observational studies have shown that anti-diabetic medications (ADMs) may modify the risk of lung cancer. We performed a systematic review and meta-analysis evaluating the effect of metformin, sulfonylureas (SUs), thiazolidinediones (TZDs), and insulin on the risk of lung cancer in patients with diabetes mellitus (DM). Materials and Methods: We conducted a systematic search of Pubmed and Web of Science, up to August 20, 2013. We also searched the Conference Proceedings Citation Index (CPCI) and China National Knowledge Infrastructure (CNKI) for abstracts from major meetings. Fixed or random effect pooled measures were selected based on heterogeneity among studies, which was evaluated using Q test and the I2 of Higgins and Thompson. Meta-regression was used to explore the sources of between-study heterogeneity. Publication bias was analyzed by Begg's funnel plot and Egger's regression test. Associations were assessed by odds ratios (ORs) with 95% confidence intervals (CIs). Results: A total of 15 studies (11 cohort, 4 case-control) were included in this meta-analysis. In observational studies no significant association between metformin (n=11 studies; adjusted OR=0.99, 95%CI: 0.87-1.12), SUs (n=5 studies; adjusted OR=0.98, 95%CI: 0.79-1.22), or TZDs (n=7 studies; adjusted OR=0.92, 95%CI: 0.75-1.13), insulin (n=6 studies; adjusted OR=1.13, 95%CI: 0.79-1.62) use and risk of developing lung cancer was noted. There was considerable inherent heterogeneity between studies not explained by study design, setting, or location. Conclusions: Meta-analysis of existing studies does not support a protective or harmful association between ADMs use and risk of lung cancer in patients with DM. There was considerable heterogeneity across studies, and future, well-designed, prospective studies would be required for better understanding of any association.
