대학의 학업성취도를 나타내는 평점평균은 많은 요인의 영향을 받는 것으로 알려져 있다. 본 논문은 형행입시제도하에서 획득 가능한 요인과 평점평균과의 관련성을 일반 화선형모형(GLM)을 이용하여 통계적으로 분석·평가하고자 한다. 여기서 얻어진 경과는 요즈음 변화가 모색되고 있는 입시제도나 대학교육제도의 개선에 적으나마 도움이 되는 기초자료를 제공할 수 있으리라 믿어진다. 분석자료는 1996, 97학년도 인제대학교에 입학한 학생들의 입시자료와 96,97학년도의 평점평균, 기숙사입사 여부 등을 대상으로 삼았다.

공간자료의 예측문제에 있어 전통적 예측방법인 크리깅방법과 최근 통계적문제 적용되기 시작한 신경망분석방법 간의 비교를 사례연구를 통해 행하였다. 일반적으로 크리깅에 의한 선형예측은 공간자료에 대한 일반적 통계모형으로서 간주되어 왔다. 한편 예측문제에 있어 뉴럴네트워크에 기초한 비모수적 방법이 관심의 대상이 되고 있으며 특히 대용량 자료의 경우 데이터마이닝 기법의 한 분야로 널리 사용되고 있는 실정이다. 본 연구에서는 공간 자료의 예측에 있어 유전자 알고리즘을 신경망분석 모형을 결합하여 기존의 크리깅방법과의 예측력을 비교한다.

The purpose of this study was to examine self esteem and reactions on LMT projective technique to a group of scientifically gifted high school students and general high school students. For that purpose, 113 participants from scientifically gifted high school and general high school were asked to fill out self esteem questionnaire and draw a LMT. The results were analyzed by using SPSS.PASW18. The results are as follows: First, overall self esteem of gifted students were higher than general students. Second, reactions on LMT of gifted students and general students were examined. As a result, there were statistically significant differences in four items; integration of landscape composition, expression of distance and space, number of additional items, existence of doors and windows. The result of this study showed significant differences between the two groups in self esteem and LMT scores.

생활수준의 향상으로 일반가정에서 사용하는 전기용품의 종류도 무척 다양해졌으며 사용량도 급격히 증가되어 이로 인한 전기재해(화재, 감전)가 끊이지 않고 있다. 행정자치부 화재통계 연보에 따르면 ''99년도 총 화재발생건수 33,856건 중 전기로 인한 화재가 11,204건으로 33.1$\%$의 높은 점유율을 보이고 있어 일반가정에서의 전기안전 생활화가 절실히 요구되고 있는 실정이다. 일반 가정생활에서 편리하게 사용하고 있는 전기를 보다 더 안전하게 사용하기 위해서 우리 모두가 꼭 알아두어야 할 전기설비에 관한 기초상식, 전기사고의 종류와 예방대책, 정전 시 대처요령 등을 알아본다.

The purpose of this study is to compare the friendship expectation that gifted students perceived in the gifted class and the regular class. To this study, friendship expectation survey, which sub-domains were intimacy, ability similarity, and morality, was conducted to 121 gifted students. The results of this study were as follows: First, according to the results of comparing the friendship expectations of gifted students in the gifted class and the regular class, there were statistically significant differences in the sub-domains of intimacy and morality. But there was no significant difference in the sub-domain of ability similarity. Second, there were statistically significant differences in the some detail items of all sub-domain(intimacy, ability similarity, and morality). Based the results of this, the implications to understand the friendship of the gifted students were suggested.

Due to the great impact of private education expenses on many areas including economics and politics, reducing private education expenses is one of the key issues in Korea. In this paper, we analyze the data from a survey on private education expenses, conducted by Statistics, Korea, in 2008. We study the effect of some demographic variables on two dependent variables, the expenses for out-of-school private education (Private) and the expenses for after-school programs (Afterschool), by using a multiple linear regression model. The analysis results show that 'residential area' and 'school level' variables have a significant effect on the two dependent variables. 'Private' increases in the order of small town, middle town, or metropolitan city, and Seoul, by about 7%. On the other hand, 'Afterschool' are about the same for all areas except for the small town. In terms of the effect of 'school level', 'Private' for high school students is about 17% larger than all other students including professional high school students. This shows a strong correlation between university admission and private education, in Korea. 'Afterschool' is larger for high school and elementary school students and decreases in the order of professional school students and middle school students. It seems that after-school programs are alternatives to expensive private education programs for elementary school students, and that high school students are attracted to after-school programs to get a good GPA, which is important for university admissions.

In this study, a survey was carried out on 150 parents who have regular children attending integrated childcare centers in J area, through March 2 to March 10, 2012, with the purpose of figuring out the Effects of Attitudes toward Disabled Children on Integrated Childcare Attitudes in Regular Parents. The results are summarized as follows. First, the effect of attitudes toward disabled children on regular integrated childcare attitudes showed that cognitive and emotional factors had a statistically significant positive effect on regular attitudes. Second, the effect of attitudes toward disabled children on children's activities and teachers' concerns for integrated childcare showed that cognitive and behavioral factors had a statistically significant positive effect on children's activities and teachers' concerns. Third, the effect of attitudes toward disabled children on behavioral problems of integrated childcare showed that cognitive, emotional and behavioral factors had a statistically significant positive effect on behavioral problems. As for findings stated as above, there was a difference in integrated childcare attitude depending on regular parents' attitude toward disabled children. This implies that there is a difference in cognitive and emotional attitudes toward disabled children in regular parents, acting as positive factors that raise the integrated childcare attitude for the improvement of perception on these factors. Consequently, for the integrated childcare, both disabled children and regular children should admit each other's diversity and accept different each other's existence, and the perception change of parents, who try to respect and learn together, should be preceded.
