본 연구는 동양신화를 기반으로 한 통합교육활동이 유아의 창의성과 인성에 미치는 효과를 알아보고자 만 5세 유아 36명(실험집단 18명과 비교집단 18명)을 대상으로 총 14회기의 프로그램을 적용하였다. 본 연구를 위하여 동양신화의 원류인 "산해경(山海經)"에 소재한 신화를 수업활동의 기본 자료로 활용하여 실험집단에게 전개하였고, 비교집단에게는 생활주제에 따른 일반적인 누리과정 활동을 시행하였다. 수집된 자료는 SPSS 21.0 통계 프로그램을 사용하였으며, 활동실행 후에는 집단별 사전검사 점수를 공변인으로 하여 공변량 분석(ANCOVA)을 하였다. 연구 결과를 보면 첫째, 동양신화를 활용한 통합적 교육활동이 유아의 창의성 전체와 모든 하위요인에서 긍정적 영향을 미치는 것으로 나타났다. 둘째, 동양신화를 활용한 통합적 교육활동이 유아의 인성에 긍정적인 영향을 미치는 것으로 나타났다. 동양신화를 대상으로 교육 텍스트를 확장하고 전환하는 작업은 유아의 창의성과 인성 신장에 도움을 줄 뿐만 아니라 유아에게 동양에 관한 새로운 이해를 도모하고 문화적 균형성을 경험할 기회를 제공해준다는 점에서 유의미하다.

공변량(covariate)이 존재하는 경우, 각 처리군 간 효과의 차이를 검정하기 위한 대표적인 비모수적 방법에는 Quade (1967)가 제안한 검정법이 있다. 또한 반응변수에 대해 공변량으로 단순선형회귀분석을 실시하여 얻은 잔차에 대해 일원배치분산분석과 Kruskal Wallis가 제안한 방법을 적용하는 방법, 그리고 Hwang과 Kim (2012)이 제안한 비모수적 도구인 위치(placement)를 이용한 방법이 있다. 본 논문에서는 공분산분석 모형에서 Hwang과 Kim (2012)이 제안한 방법을 확장하여 공분산분석에서의 새로운 방법을 제안하였다. 또한 모의실험(Monte Carlo simulation study)을 통하여 기존의 검정법들과 제안한 방법의 검정력을 비교하였다.

Purpose: Glufosinate ammonium (GA; phosphinothricin) can induce neurological complications such as altered mental status, amnesia, and convulsions. This study was conducted to evaluate whether blood lipid profiles can help predict convulsions in patients with GA poisoning. Methods: This study was a retrospective review of data acquired at a tertiary academic university hospital from March 2014 to July 2016. Independent t-test, Mann-Whitney test and Analysis of covariance (ANCOVA) of demographic and laboratory findings of 50 patients with GA poisoning were performed to identify correlations of general characteristics and laboratory findings, including blood lipid profiles of GA-poisoned patients between with and without convulsions. Results: Convulsion as a GA complication showed a significant association with poison volume, age, white blood cell count, and creatine phosphokinase (CK), albumin, lactate dehydrogenase (LDH), low-density lipoprotein (LDL), and high-density lipoprotein (HDL) content in blood according to an independent t-test and Mann-Whitney test. However, ANCOVA demonstrated significant association with LDL and triglyceride. Conclusion: Blood lipid profiles, especially serum LDL and triglyceride, were useful in predicting convulsions in patients with GA poisoning.

The study examined the effects of explicit derivational morphology instruction (henceforth DMI) on the incidental vocabulary acquisition and reading comprehension of 132 Korean 1st-year high school students who responded to a battery of tests (two vocabulary tests and a reading comprehension test). Multiple statistical tools were used to analyze the data: Analysis of Covariance (ANCOVA), Analysis of Variance (ANOVA), Simple Regression Analysis, Tests of Simple Main Effects, and effect size computation using Cohen's d. The results indicated that (a) DMI enhanced students' ability to infer word meanings in context, (b) DMI promoted high proficiency students' reading comprehension, whereas it impeded intermediate proficiency students' reading comprehension, (c) vocabulary knowledge has a strong positive predictive value for reading comprehension, and (d) the gaps of vocabulary knowledge across proficiency levels were still substantial, despite the observation that DMI promoted students' vocabulary acquisition. These results have a bearing on English as Foreign Language (EFL) reading pedagogy.

This study aimed to examine the effects of science activities connected to physical expression on the four-year-old children's creativity. This study conducted an observation of sixty-four children of four years of age attending the kindergartens in the city of Seoul. Thirty-seven were classified in the experimental group and the remaining twenty-seven were in the comparative group. For the statistical analysis of the data collected, the t-test and the analysis of covariance(ANCOVA) were conducted. The findings of this research are as follows. The children of the experimental group who experienced science activities connected to physical expression demonstrated higher score than those of the comparative group in creativity. The result of the research indicates that science activities connected to physical expression, for children, enhances their creativity. Therefore, science activities connected to physical expression can be an effective approach for creativity of young children.

Purpose: This article provides the efficiency test results of conducting depot maintenance. Method: ANOVA (analysis of variance) and ANCOVA (analysis of covariance) tests are conducted using data obtained from Defense Logistics Integrated Information System (DELIIS). Results: The result shows that although the effect of the depot maintenance is significant, some parts do not follow the overall effect of the depot maintenance. In order to solve the problem we provide some suggestions to be improved. Conclusion: For improving the combat readiness condition of K-1 main battle tank, the maintenance policies and regulation must be revised for the parts of the weakness. In addition, the collection way of the operation and maintenance data must be redesigned.

The purpose of this study was to assess the effects of a children sexual abuse (CSA) parental training program with applied developmental bibliotherapy on parents. Subjects were 54 mothers, 24 of whom participated in the program which included 8 sessions for 4 weeks. Four dependent variables were subjected to analysis of covariance (ANCOVA); mothers’ knowledge, myths and stereotypes related to CSA, and their children’s levels of prevention concepts comprehension and self-protection skills of CSA. The results showed that the program increased mothers’ knowledge of CSA and decreaesd their beliefs on myths and stereotypes, and also increased their comprehension level of CSA prevention concepts and their level of children self-protection skills. These positive effects of the program show that the program can be incorporated into early childhood education practices. We are also pursuing the development of other research programs on this subject.

This study focuses on the relationship between ethnic identity of Asian-Americans and their appreciation of their ethnic body features, based on reference group theory. A convenience sample of 60 male and 52 female students from various Asian ethnicities attending a mid-western university was used for the study. A 2 (gender) by 2 (ethnic identification) by 2 (socializing group) analysis of covariance (ANCOVA) on body image satisfaction as dependent variable and Body Mass Index score as a covariate was conducted. A significant main effect of ethnic identification was found, which indicates the more respondents identified with their ethnic group, the more likely they were to be satisfied with their appearance. The social group affiliation main effect was not significant. The impact of ethnic identification was significant only for those respondents who socialize more with Americans than with Asians. The results support the idea that one's ethnic group functions as a reference group, which influences body image appraisals.

This study investigated the effectiveness of mathematical activities based on picture books for the development of children's problem-solving performance. Subjects were 72 children divided in two groups of 36 each; one group had mathematical activities based on picture books and the other group had of pencil-and-paper tasks. The problem-solving performance was measured in terms of the test by Ward(1993) with a few modification for pretest and posttest. Mathematical activities were performed 12 times over a 6 week period. The data was analyzed by Analysis of Covariance(ANCOVA). The group taught by picture books significantly improved mathematical problem-solving performance.
