  • Purpose: We comprehensively analyzed domestic studies on the effects of death preparation education in order to present objective data. Methods: Meta-analysis was conducted with a total of 22 master's and doctoral theses published between 2004 and 2014. Results: According to our analysis, the death preparation education had a mid-size effect. The effect size of a moderator variable was the greatest in infants and children, and the effect size was bigger in younger ages. The effect size was the greatest when education was given through a total of 10~15 sessions, twice a week, and less than 60 minutes per session. The effect variable and death-related variable showed a significant effect size, and sub-variables were equivalent to the death-related variable with a biggest effect size. Non-death related variables had a mid-level effect size and sub-variables were found to have the highest ego integrity. Conclusion: The significance of this study lies its systematic integration of advanced research on the effects of death preparation education through meta-analysis. By suggesting guidelines for the design of a death preparation education program, evidence-based basic data were proposed which will more likely strengthen intervention effects. Based on these results, more studies are needed to develop and extensively carry out a death preparation program which can meet needs of specific age groups from children to seniors.

  • When the ultimate strength of a concrete flexural member is evaluated, the effect of member size is usually not considered. For various types of loading, however, the strength always decreases with the increment of member size. In this paper the size effect of a flexural compression member is investigated by experiments. For this purpose, a series of C-shaped specimens subjected to axial compressive load and bending moment was tested using three different sizes of specimens with a compressive strength of 528 kg/$cm^2$. According to test results the size effect on flexural compressive strength was apparent, and more distinct than that for uniaxial compressive strength of cylinders. Finally a model equation was derived using regression analyses with experimental data.

  • The purpose of this study was to investigate the effect size of non-pharmacological intervention applied to patients with anxiety disorder and to provide information about evidence-based intervention. Twenty three studies were selected for meta-analysis through a systematic review of domestic studies. We searched journal articles published in Korea up to May, 2015 using the key words "Anxiety Disorders (MeSH)" and "Treatment or Intervention". Meta-analysis was performed using a random effects model, and the effect sizes on each of anxiety and depression were calculated. The effect size for anxiety of non-pharmacological intervention in this study was Hedges' g=1.693 (95% CI; 1.267-2.120), indicating a large effect size. The effect size for depression was Hedges's g=1.571 (95% CI; 0.481-2.661), indicating a large effect size. It is significant that this study systematically synthesized the study results for non-pharmacological intervention effects applied to patients with anxiety disorders in Korea. It also established a basis that can be applied to nursing intervention.

  • Over two decades, many researchers have performed studies on strength size effects in composite laminates under tensile and flexural loads. It is well known that there is a tendency for the strength of fibre-reinforced composites to decrease with increasing specimen size. Under compressive load, however, little work has been done on the effect of specimen size to failure strength. This is due to the fact that compressive testing of composite is very difficult. In this paper, the effect of the test specimen size on the compressive strength of composites containing open hole was considered using T300/924C, $>[45/-45/0/90]_{3S}$. For sizing test specimens, the in-plane scaling method is used i.e., the change of two- dimensional specimen area in specimen width and gauge length. The results clearly show that there is a hole size effect in the finite width plates. In addition, the specimens which have the same a/W(hole diameter/specimen width) exhibit a tendency of size effect. In contrast, test results of the unnotched specimens did not show a clear strength size effect.

  • The purpose of this study is to use meta-analysis as a research method to investigate the correlation between early child teachers' teaching efficacy and their job satisfaction, and thereby look into the effect size of the two variables and their sub-variables. To achieve the purpose, this researcher chose a total of 37 theses for analysis and collected 289 data for analyzing the effect size. Based on the data, CMA(Comprehensive Meta Analysis) 2.0 was applied. According to the analysis, the correlation between early childhood teachers' teaching efficacy and their job satisfaction was higher than the medium effect size on the basis of Cohen(1992) research. In the sub-variables of teaching efficacy, the correlation of personal teaching efficacy with job satisfaction showed higher effect size than that of general teaching efficacy. In the sub-variables of job satisfaction, the correlation between the belief in job and teaching efficacy showed the highest effect size. In terms of thesis type as a moderating variable, Ph.D dissertations showed higher effect size than journals or M.A. theses. As the result of the meta-analysis on publishing year and the number of samples, there was no statistical significance. On the basis of the analysis results, discussions and limitations of this study were suggested.
