The purpose of the National Assessment of Educational Achievement(NAEA) is not only to assess educational progress and achievement but also to collect background information affecting educational achievement. It is important to know which factors affect the National Assessment of Educational Achievement(NAEA) and to explore how much those factors show the educational effect. In this study, first, we examined general characteristics of the survey with relation to the background information. Second, we analyzed the relationships between test scores and information on the students' profile such as background, extracurricular activities, and information on the school profile in NAEA 2004. Third, we suggested some educational policies on the basis of those analysis and indicated the limitation of this study.

The purposes of this research are: to observe the related variables; to compare the effect size; and make suggestions for leadership selection by admission officer system based on the results from the observation and comparison through meta analysis. The research questions crafted in order to achieve the purpose are as follows. First, what kind of variables were discussed in the previous studies? and can these variables be classified as the categories of the existing studies? Second, how are the effect sizes of the youth leadership related variable groups? Third, how are the effect sizes of sub factors of the related variable groups? The specific results of this research are as follows. First, youth leadership related variables can be classified as demographic, organization-activities, home environment and sociopsychological variables. Second, sociopshycological variable group shows the largest effect size. Third, among the sub factors, self esteems (ES=1.3231) and degree of satisfaction for life (ES=1.1737) show two largest effect sizes. In conclusion, based on the result of the research, this research suggests an alternative for a method to select students through admission counseling leadership selection system.

본 연구는 가정관리유형, 의사소통도 및 가사협조도 간의 관계를 규명하여 가정내일의 협조도를 향상시킬 수 있는 가정관리자의 관리유형 규명과 의사소통의 중요성을 밝히고자 하였다. 자녀를 1명 이상 둔 청주시 주부 418명을 대상으로 1993년 12월 중순부터 1994년 1월초까지 설문지 조사를 하였다. 자료는 SAS/PC program을 사용하여 Mean, F-test t-test, Duncan's 사후검증 다중회귀분석, 경로분석을 실시하였다. 연구결과를 요약하면 다음과 같다. 1) 사회인구학적인 변인중 가정관리유형에 영향을 미친 변인은 부부의 교육수준, 가정생활주기였다. 2)사회인구학적인 변인중 의사소통에 영향을 미치는 변인은 부부연령과 교육수준, 가정생활주기, 자녀수, 가족형태였다. 3) 사회인구학적인 변인중 가사협조도에 영향을 미치는 변인은 남편직업, 가정생활주기, 자녀수, 가족형태였다. 4) 가정관리유형, 의사소통 및 가사협조도 간에 관계를 경로분석하여 본 결과 가정관리유형은 의사소통에 영향을 미치고 가사협조도에 간접적인 영향을 주는 변인이었다. 부언하면 가정관리자가 인간중심적인 관리유형을 취할수록 가족 내 의사소통도가 높아지고 더불어 가사협조도도 증대된다.

Meta-analysis was conducted on 34 studies reported in Korea from February 2007 through March 2017 to systematically integrate factors of aging anxiety of the middle and old aged. The variables related to aging anxiety were divided into 6 groups of variable, and the effect sizes were computed for each variable of their groups. The results are as follows. First, the total effect size showed the middle effect size, and the effect size according to the variable group showed the largest effect size for the negative psychological variable group, followed by the positive psychological variable, the social variable, the physical variable, the familial variable and the demographic variable. Second, the largest effect size of the sub-variables showed psychological well-being and death anxiety. As described above, suggesting that these variables may have a strong influence on aging anxiety among the variables related to aging anxiety because the psychological well-being and death anxiety were shown as the largest effective variables related to aging anxiety.

The purpose of this study is to identify the effect size of protective variables and risk variables based on the previous study which is related to nurse burnout. Master's doctoral and journal degrees from 2005 to 2014, a total of 116 articles side by conducting a meta-analysis suggests a convergence conclusions. The biggest effect size of a nurse burnout protection variable was job variable and the largest effect sized of sub-variable was empathy satisfaction. The biggest effect size of the nurse burnout risk variables was organization variables, the largest effect size of sub variables was the violent reaction. Based on the results of this research, a variety of programs and policy measures for appropriate interventions and arbitration of nurse burnout should be built to decrease the risk variable which can cause nurse burnout and reinforce the protection variable that restrains a nurse burnout.

The purpose of this study was to examine the impact of psychosocial protective and risk factors on problem drinking among American adolescents. In addition, this study investigated the compensatory and buffering effects of psychosocial protective factors. The sample consisted 4,362 10th graders taken from the Monitoring the Future Study 2002. This study performed the hierarchical regression analysis for data analyses. The main findings provided that friend influence, sensation-seeking, and tolerance of deviance had significant positive relationships with problem drinking as risk factors. This study also revealed that negative perception on drinking, parental bonding, school bonding, and prosocial activity had significant direct impacts in decreasing problem drinking, which explains the compensatory effect of protective factors. Additionally, this study showed that negative perception on drinking had a significant buffering effect moderating friend influence on adolescents' opportunities exposed to problem drinking. The results of this study suggest some practical implications for preventive intervention programs that target adolescent problem drinking.

In an effort to identify predictors of job performance, research studies in social work administration has been so far on the individual practitioners' levels of knowledge and skills, which could be used in a workplace. As the theoretical concept of organizational environment was fully introduced into social work administration research, however, studies on practitioners' job performance began to have interest in the team or the organizational level variables as well as individual level variables. Along the course of this tendency, this study attempted to test the effect of individual, team, and organizational level variables on the job performance of human service workers. The individual level variables consisted of knowledge, skills, job satisfaction, personality, and counter-productive work behaviors of workers. The team or the organizational level variables included situational constraint, organizational justice, job characteristics, government-dependency, and inter-organizational cooperation. Multi-level complex survey data collected by cluster sampling method from 314 practitioners in 23 organizations were analyzed using Hierarchial Linear Model. Results showed that both task and contextual performance were affected by individual, team, and organizational level variables in various ways.

The purpose of this study was to regression analysis for variables on effect of development of scientific thinking. The subjects sampled in this study was 117 5th grade students, 131 8th grade students, and 127 11th grade students. The students were administered test of 10 questionnaires. The GALT(group assessment of logical thinking), FIT(figured intersection test), and GEFT(group embedded figural intersection test) were used which developed previous researchers. And other questionnaires were modified. The result of this study showed that cognitive variables, psychological variables, home variables and learning environment variables made effects on scientific thinking. Cognitive variables, psychological variables, home variables, and learning environment variables explained 60%, 10%, 5% and 10% to scientific thinking. All of those variables explained around 86%. Overall, 5th, 8th and 11th grade models were similar but with some differences in the effects of contextual variables with in the models.
