The results of the study are as follows. Firstly, the competencies of teacher for organizing and operating of NCS based curriculum are composed of the following 4 areas, 11 competencies and 35 sub-competencies. 'Needs and learning environment analysis(area 1)' is composed of 2 competencies of 'analyzing needs', 'analyzing learning environment', and their 7 sub-competencies. 'Curriculum organization(area 2)' is composed of 4 competencies of 'organizing and operating curriculum committee', 'setting educational goals and workforce type', 'analyzing and selecting NCS competency units learning modules', 'developing subjects', and their 10 sub-competencies. 'Curriculum operation(area 3)' is composed of 3 competencies of 'preparing teaching-learning activities', 'implementing teaching-learning activities', 'evaluating teaching-learning activities', and their 15 sub-competencies. 'Curriculum evaluation and feedback(area 4)' is composed of 2 competencies of 'evaluating curriculum', 'giving feedback on the curriculum', and their 3 sub-competencies. Secondly, the relative importance of the competencies is as follows; 'implementing teaching-learning activities' has the highest relative importance of 19.6%, followed by 'evaluating teaching-learning activities'(14.2%), 'evaluating curriculum'(12.5%), 'giving feedback on the curriculum'(11.2%), 'preparing teaching-learning activities'(9.2%), 'developing subjects'(8.6%), 'analyzing and selecting NCS competency units learning modules'(7.5%), 'setting educational goals and workforce type'(6.6%), 'analyzing learning environment'(5.4%), 'analyzing needs'(3.9%), 'organizing and operating curriculum committee'(1.5%).

This study presents results by the content areas in mathematics. Average performance is provided for five content areas: number, algebra, measurement, geometry, and data. Relative achievement is shown among the content areas for 4 countries in comparison to Korea. In number, Korea had lower average achievement than Singapore, especially for ratio proportion percent. Among 5 countries, Korea had the highest average achievement in algebra and geometry, but the lowest in attributes and units of measurement. In data, Korean students didn't learn the followings successfully: a) comparing characteristics of data sets and using mean, median, range, and shape of distribution, b) interpreting data sets (e.g., draw conclusions, make predictions, and estimate values between and beyond given data points), c) evaluating interpretations of data with respect to correctness and completeness of interpretation.

최근 정보통신기술의 발전과 함께 영상매체의 급속한 증가로 영상의 효율적인 관리와 검색의 필요성이 요구되면서 내용기반 영상검색이 핵심기술로 대두되고 있다. 내용기반 영상검색에서 영상의 특징을 표현하기 위해 색상 히스토그램을 많이 사용하고 있으나, 색상만을 고려하는 것은 많은 단점을 지니고 있으므로 본 논문에서는 먼저 순차영역분할(sequential clustering)기법을 도입하여 영역을 분할하며, 분할된 영역의 색상평균값과 영역의 중심점으로부터의 거리 히스토그램을 영상의 특징으로 구하여 이를 비교함으로써 색상과 공간정보를 함께 고려하는 방법을 제안한다. 제안된 방법의 특성의 수가 18개로 타 방법보다 매우 작은 저장공간을 가지면서도 동시에 검색효율이 8.5% 이상 개선되었다. Precision 대 Recall에서도 각 질의영상에서 대부분의 Recall 값에서 제안한 방법의 우수함이 확인되었으며, 시각적으로도 양호한 검색결과를 얻을 수 있었다.

The contents of geographical education present too inclusive and abstract regard as criteria in an existing curriculum. And geographical education oneself's system is difficult because they are set to the one part of educational side. This study pursuit to make content standard of geographical education based on geography as an alternative. This paper present standard setting up 5 steps. They are Ultimate Theme, Basic Theme, Major Standard, Standard, Detailed Standard. Ultimate Theme is discern geographical education whole : understand of interaction human and environment, understand of place and region, understand of interaction human and region. Basic Theme is concrete of ultimate theme ; geographical skill, physical environment, human environment, place and region, interaction of human and region. Standard is concrete and measurable level of basic theme, it is consist of three steps in Major Standard, Standard, Detailed Standard tv level of specification. Major Standard is consist of 17 item, Standard is 48 item, and Detailed Standard is detailed to unit level.
