A male sterile facilitated recurrent selection population was developed by the barley breeding team of Yeongnam Crop Experiment Station. To breed this population, three composite cross populations and a composite population of breeding lines in our country were used as the materials. This population was developed in order to breed early maturing, wet-soil tolerant and high yielding barley varieties, adapted for double cropping with rice in southern part of Korea. The population was named by RSPYB#l which means Recurrent Selection Population No.1. of Yeongnam Barley.

The purpose of this study is to analyze selection methods of gifted students. This study focuses on the understanding the characteristics of gifted students in accordance with the selection methods, i.e. the examination selection and automatic promotion by analyzing and comparing the academic emotion, meta-cognition, and self-efficacy between gifted students selected according to the selection methods. Moreover, for the purpose of the effective gifted education, this study aims to arrange a reasonable basis for the discrimination and selection of gifted students. The results of this study were as follows. First, there was no meaningful difference between gifted students selected by an examination and promoted automatically in view of academic emotion, meta-cognition, and self-efficacy of gifted students. It is determined that there is no difference between the effects of selection methods under the condition of the same group of gifted students. Second, regarding the academic emotion of gifted students, there is no significant difference in both the elementary and middle school in case of examination selection. However, in case of the automatic promotion, the academic emotion of gifted students promoted automatically in the gifted education center was higher than that of the gifted students in the gifted class (p < .05). Regarding the meta-cognitive skill, there is no difference in the elementary school between the selection methods. In case of the examination selection in the middle school, the meta-cognitive skill of male students of the gifted education center was higher than that of the female and gifted class students (p < .05). In case of the automatic promotion in the middle school, the meta-cognitive skill of students of the gifted education center was higher than that of students of the gifted class (p < .05). As for the case of self-efficacy, there were no differences between the selection methods. In the automatic promotion, self-efficacy of students of the gifted education center was higher than that of students of the gifted class (p < .05).

The purpose of the present study is to compare paper and pencil test utilized to identify gifted students so far to the recently introduced teacher observation-recommendation system. More specifically, this study compared intelligence, career patterns, and self- regulated learning abilities of gifted students who were identified through those two different identification system to explore the possibility of the newly introduced teacher observation-recommendation system. The results show that there was no significant difference in the aspect of overall IQ score. However, students who were identified through the observation-recommendation system showed significantly higher scores at some subscores of intelligence test, such as vocabulary application, comprehension, and schematization. In the aspects of career patterns, about 72% of gifted students who were identified through the previous paper and pencil test belonged to the 'investigative' category of Holland. But more diverse career patterns such as enterprising, social, realistic, conventional including investigative categories were found in those students who were identified by the observation-recommendation system. There were also significant differences in the self-regulated learning abilities between two groups of students. Practical implications of the study were discussed in depth.

The purpose of this study is to propose issues in selecting gifted children in mathematics by in-depth analysis of the selection process and items. In order to accomplish the purpose, the rate of right and wrong answers were examined based on the reaction of the students by 1st, 2nd and 3rd selection test. Also, the types of the errors were identified for the 2nd and 3rd selection test. According to the study results, the rate of right answers was low in short response questions and essay questions rather than in multiple-choice questions. In addition, the academic achievements were lower in the fields other than number & operations and logic. The conclusion of this study is that following studies regarding selection of gifted children are required linked with the project tasks and programs.

대학이 신입생을 선발하는 기준은 해당전공을 공부하는데 적합한 지원자를 선발하는 것이며, 해당모집단위에 많이 지원하게 하여 신입생 충원을 용이하게 하는 것 등이다. 대학은 입학전형을 거쳐서 신입생을 선발하게 되며, 선발기준으로 전형요소를 활용하게 된다. 전형요소 활용방법은 신입생 선발에 영향을 주기 때문에 전략적으로 중요하다. 2005학년도 신입생 선발에는 고등학교 7차 교육과정을 이수한 지원자들이 지원하게 되므로 전형요소에 있어서 변화가 있다. 대학입학수학능력 시험의 체제는 수험생들이 영역이나 과목을 선택하여 응시하는 방향으로 변화한다. 즉, 수리 영역을 가형 및 나형으로 응시하고, 하나의 탐구영역을 응시하되 사회탐구영역 및 과학탐구영역은 4과목 이내에서 선택하여 응시한다. 또한 수학능력시험의 성적표는 각 영역별 및 과목별 표준점수, 백분위점수 및 등급을 표시하여 통지한다. 본 연구는 변화된 수학능력시험의 체제와 고등학교 교육과정을 어떠한 방법으로 반영하여 학생을 선발하는 것이 바람직한가에 대한 전략을 도출하는 틀을 제시하고, 각 전형요소 활용의 대안과 문제점을 도출하고자 한다. 2005 수능시험 결과는 표준점수로 통지하기 때문에 만점 개념을 적용하기 어렵고, 표준점수를 전형요소로 활용할 때 전형총점 개념을 도입하기 어렵다. 또한 복수영역 및 과목의 선택에서 유리함과 불리함이 나타나게 된다. 과거의 수능시험결과를 분석하여 전형총점개념 도입의 방법과 불리함을 보정하여 주는 방법을 제시하고, 신입생을 선발하는 목적에 적합한 전형요소 결정전략을 도출하고자 한다.2; Learning Decisions, 2001) 연구모형을 설정하고 이를 근거로 실증연구를 수행 중에 있다.7.2 $e^{0.101}$x/, y = 70.01 $e^{0.030}$x/, 반감기는 12.0, 6.86, 23.0 일이고 폐장, 간장, 신장의 회복기간(x)별 크롬농도(y)의 소실속도 상관계수 (노출농도 0.50 mg/㎥군의 경우)는 y = 1808 $e^{0.004}$93x/, y = 12.02 $e^{0.029}$7x/, y = 67.61 $e^{0.029}$2x/ 반감기는 140.6, 23.3, 23.7 일로 평가되었다. 4. 고찰 : 실험동물의 전혈, 혈청, 뇨에서의 크롬농도와 시험물질 노출농도는 밀접한 상관을 가졌으나 농도에 정비례하지는 않았다. 뇨 중 흡수된 크롬의 경우 회복기간 초기 (12시간 내)에 대부분 배설이 일어나는 것으로 나타났다. 폐장이 간장, 신장 등 다른 장기에 비해 높은 축적량을 보였으며 축적된 크롬농도가 높을수록 크롬의 소실속도는 현저히 저하하는 경향을 보였다. 노출농도가 높을수록 각 장기조직 내 크롬의 소실속도 (clearance)는 크게 감소경향이 있었으며 이는 체내 과부하시 자정작용이 감소하는 것으로 판단되었다. 본 연구 결과 SD rat를 이용 반복흡입노출의 경우 생체의 무유해영향농도 (NOAEL)는 0.2mg/㎥이하이며 발암물질을 감안하여 안전계수를 100으로 할 경우 사람에 대한 NOAEL은 0.002mg/㎥이하로 판단되
