Purpose: The purpose of this study was to identify the effects size of simulation education targeting korean nurses and nursing students. Methods: Meta-analysis was conducted with 48 papers in domestic master and doctorate degree dissertations and academic journals from 2000 to 2014. Results: The entire effect size in simulation education was relevant to big effect size. Regarding the effect size of individual variables, nurse was identified to have biggest effect size in study subject, standardized patient was identified to have biggest effect size in simulation methods and pediatric nursing was identified to have biggest effect size in study subjects. Effect size in each effect variable was highest in psychomotor domain. Conclusion: This study identified the effect size of simulation education and provided the basic data to contribute to the quality improvement of simulation education which is based on the reasons.

메타분석은 이전의 연구들의 결과를 결합하기 위해 많은 분야에서 널리 사용된다. 메타분석 방법들 중에 p-value의 통합은 가장 단순한 방법이며 Tippett (1931), Fisher (1932) Stouffer 등 (1949) 등이 p-value를 통합하는 다양한 방법들을 제안하였다. 이 논문에서 우리는 지수분포에 기초한 새로운 p-value의 통합 방법을 제안하였다. 또한, 몬테카를로 모의시험 연구를 통해 제안된 방법과 이전의 방법들의 검정력을 비교하였다.

Aflatoxins are natural contaminants of poultry feeds and feed ingredients and cause liver damage, immunosuppression, reduction in performance and mortality in broilers. A number of studies have been carried out to study the effects of aflatoxin on feed conversion ratio in broilers. The results on feed conversion ratio of 10 research articles in broilers fed with aflatoxin from first day of age to six weeks of age were compiled and were subjected to meta-analysis. Chi-square test and $Tau^2$ (heterogeneity co-efficient) were applied to test for significance of heterogeneity of studies. To integrate results, fixed effect model by Inverse Variance method (IV method) was used when heterogeneity was insignificant and otherwise random effect model by DerSimonian and Laird Method (DL method) was used. The results of meta-analysis showed that the adverse effect of aflatoxin on feed conversion ratio at the end of first week was negligible, second week was medium and third to six weeks was very large.

As a result of physical characteristics of using meta-kaolin and alkali accelerator, it was found that higher curing temperature density is favorable to strength development at early age and the higher the age is, the higher, most of the compressive strength gets. Also, I was shown that more than atmospheric curing, steam curing was favorable for development of compressive strength. When the temperature of curing temperature was higher, most of the compressive strengths were higher. Thus, based on this study, it was understood that environmental-friendly chemically combined concrete using meta-kaolin and alkali accelerator can be utilized without using cement.

본 연구는 프라스카가 제시한 파이디아와 루두스의 개념을 통해 오픈 월드의 중첩적 플레이 구성 형식을 고찰한다. 구조화된 시뮬레이션적 체계로 구성된 오픈 월드는, 비선형적 이벤트와 선형적 퀘스트를 통해 광활한 지리적 공간을 중첩적으로 구성한다. 이때 파이디아적 상호작용 과정을 통해 공간을 탐험하며 고유의 시퀀스를 축적한 플레이어는, 완결적 스크립트를 기반하는 루두스적 퀘스트의 결과와 충돌한다. 대안으로 제시된 메타시뮬레이션은 메타 모델의 편집 및 생성 도구로 운용되며, 대안적이고 확장된 의미의 게임 플레이 활용을 제시한다.

Purpose: This study was conducted to meta-analyze the effects of hardiness on health-related variables. Method: After review of 19 studies performed by Korean nurses, research variables, statistical data(r or F), and other methodological data were extracted and coded. Research variables were categorized under 5 groups such as health-related behavior, well-being, adaptation, stress, and support according to conceptual similarity. Using SAS program, 20 research variables and 34 effect sizes were calculated after eliminating heterogeneous data by Q-test, Results: Effects of hardiness on whole research variables was .512 and ranged from .322 to .643 by categories. The greatest effect was obtained from well-being category, whereas the smallest effect from stress category. All effect sizes were statistically significant. But fail-safe numbers were small and failed to achieve reasonable tolerance level. Conclusion: Results of meta-analysis indicated that hardiness has a moderate effect on health-related variables. But for improving the reliability of the results by minimizing publication bias, the more hardiness studies should be done.

Usability evaluation(UE) experiments are conducted to provide UE practitioners with guidelines for better outcomes. In UE research, significant quantities of empirical results have been accumulated in the past decades. While those results have been anticipated to integrate for producing generalized guidelines, traditional meta-analysis has limitations to combine UE empirical results that often show considerable heterogeneity. In this study, a new data mining method called weighted bi-clustering(WBC) was proposed to partition heterogeneous studies into homogeneous subsets. We applied the WBC to UE empirical results and identified two homogeneous subsets, each of which can be meta-analyzed. In addition, interactions between experimental conditions and UE methods were hypothesized based on the resulting partition and some interactions were confirmed via statistical tests.

This study was conducted to analyze the effects of parenting programs for children with disabilities through meta-regression analysis of experimental studies published in Korea. Twenty-two studies with a randomized or non-randomized control group prepost test design were included in the analysis. Parenting programs had a significant effect on parenting stress (ES= -1.08, p <.001, $I^2=67.4%$), parenting ecacy (ES=0.72, p <.001, $I^2=58.0%$) and self-esteem (ES=0.58, p =.016, $I^2=0$). The meta-regression analysis showed that research designs and therapy providers had different effects on dependent variables. Results support that parenting programs are helpful for parents of children with disabilities in reducing parenting stress and improving parenting efficacy, and self-esteem.

Heat and flame protecting cloth is usually made of meta aramid fiber because of its own properties. But the high inter molecular hydrogen bonding and high Tg is the reason of the difficulty to dye meta aramid fiber. Recently, it was commercialized that the easily dyeable meta aramid fiber(AMD) for improving dyeability. In this study, the dyeing properties of AMD dyed with cationic dyes were investigated. The K/S values of AMD were 5~10% higher than these of general meta aramid fiber(AM) in the case of 1%owf caused by the lower crystallinity of AMD. The difference between K/S values of AMD and AM was increased as increasing dyeing concentration. The washing and rubbing fastness grade of AM and AMD were similar and good to very good.
