수십만명의 대입응시자와 대학입학을 준비하는 수백만명의 초중고등학교 학생들에게 공정한 경쟁의 규칙과 측정방법을 마련하여 적응하는 것은 매우 중요하다. 현행 대학입학 수학능력 시험에서 각 영역별 표준점수는 응시계열인 인문계열, 자연계열, 예체능계열로 나누어 각 계열의 평균과 표준편차를 사용하여 계산한다. 따라서 동일한 점수도 어느 응시계열에 속하는가에 따라 표준점수가 달라지게 되며, 상이한 표준점수를 사용하여 대등한 경쟁을 하는 경우가 있어 불공정성이 제기된다. 비록 변환표준점수로 조정하여 계열간 불공정이 어느 정도 조정되지만, 자신의 점수에 비하여 집단의 평균점수가 낮을수록 변환표준점수가 증가하게 되므로 계열선택의 영향이 없다고 보기 어렵다. 이러한 결과로 유리한 계열로 대거 이동하는 현상이 나타나고 있다. 본 연구는 대학입학에 필수적인 대학입학 수학능력시험에서 계열간 실력차이를 보정하여 공정한 경쟁을 가능하게 하는 표준점수 계산방법을 제시하였다. 또한 모든 과목이 선택과목이 되는 2005학년도부터 시행될 수학능력시험에서 과목간 표준점수를 보정하는 방법을 제시하였다 본 연구는 결론을 도출하는데 있어 응시자들간 표준점수의 차이는 응시과목에 따라 달라지지 않는다는 과목의 동질성을 가정하였다. 응시과목의 동질성 가정하에서 집단간의 표준점수를 보정하는 방식은 동일한 시험문제로 각 집단이 시험을 보는 경우 집단간의 차이만큼을 표준점수에 합하여 보정하고, 각 집단이 고유하게 응시하는 시험과목은 공통과목의 차이만큼을 각 집단에 보정하여 주는 것이다. 과목간에 표준점수를 보정하는 방식은 해당과목에 응시한 응시자들이 다른 과목에서 획득한 표준점수의 평균치로보정하는 것이다.하기 위해서, 기업간 프로세스 협업(collaboration) 부분의 데이터 및 서식, 이를 취급하는 기능과 프로세스에 대란 분석을 통해 업무 프로세스 모델링 방법론과 관련한 모델링 지침 및 메타모델을 이용한 표준 업무 프로세스 모델을 개발하여 기업간 업무 프로세스 표준화에 대한 체계적인 관리에 대한 방안을 연구하고자 한다.의Bullwhip effect를 감소시킬 수 있는 장점이 있다. 동시에 이것은 향후 e-Business 시스템 구축을 위한 기본 인프라 역할을 수행할 수 있게 된다. 많았고 년도에 따른 변화는 보이지 않았다. 스키손상의 발생빈도는 초기에 비하여 점차 감소하는 경향을 보였으며, 손상의 특성도 부위별, 연령별로 다양한 변화를 나타내었다.해가능성을 가진 균이 상당수 검출되므로 원료의 수송, 김치의 제조 및 유통과정에서 병원균에 대한 오염방지에 유의하여야 할 것이다. 확인할 수 있었다. 이상의 결과에 의하면 고농도의 유기물이 함유된 음식물쓰레기는 Hybrid Anaerobic Reactor (HAR)를 이용하여 HRT 30일 정도에서 충분히 직접 혐기성처리가 가능하며, 이때 발생된 $CH_{4}$를 회수하여 이용하면 대체에너지원으로 활용 가치가 높은 것으로 판단된다./207), $99.2\%$(238/240), $98.5\%$(133/135) 및 $100\%$ (313)였다. 각각 두 개의 요골동맥과 우내흉동맥에서 부분협착이나 경쟁혈류가 관찰되었다. 결론: 동맥 도관만을 이용한 Off pump CABG를 시행하여 감염의 위험성을 증가시키지 않으면서 영구적인 신경학적 합병증을 일으

The present research explores the tendency of the items that require Place Location Knowledge (PLK) of the Korean Geography subject in the College Scholastic Ability Test. The major findings are as follows. First, the geographical regions of the items are spatially skewed, especially in the Yeongnam regions, which are tested more frequently compared to the others. Second, the fact-based items more concern with regionality such as geographic indication system and regional festivals. Third, the concept-based items can be divided into physical geography and human geography and there were four items related to economic geography. Fourth, students tend to find it challenging in the items asking PLK. The difficulty varies according to the type of items. The students find concept-based items which require high-order thinking more challenging. There is also differences identified between contents. For example, the section of physical geography, especially climatology-related, were considered the most challenging followed by those of economic geography. Finally, the differences in the rate of correct answer are associated with the scale of the regions covered in the items and students experienced more difficulty in the items asking more precise scale.

The purpose of this study is, targeting 5th and 6th grades mathematically gifted elementary students, to analyze the effect of independent study project learning on self-directed learning ability and mathematical self-efficacy, and based on the results, examine the implications that independent study project learning has in special education for the gifted. In order to solve the study problems, 5th grade mathematically gifted elementary students(40) and 6th grade mathematically gifted elementary students(39) who had passed the selection criteria of D education institute for the gifted and had been receiving special education for the gifted were selected. The study results are as below. First, although self-directed learning ability had no significant difference at p<0.05, it statistically had some differences in averages between pre-test and post-test results. Second, although mathematical self-efficacy had no significant difference at p<0.05, it statistically had some differences in averages between pre-test and post-test results. Third, in the aspects of self-directed learning ability and mathematical self-efficacy, independent study project learning had a more positive effect on 5th grade mathematically gifted elementary students than 6th grade mathematically gifted elementary students. In addition, it had significant differences in 'the level of mathematical tasks', a sub-level of mathematical self-efficacy, and 'the openness of learning', 'the initiative of learning', and 'a sense of responsibility for learning', sub-levels of self-directed learning ability. These results imply that independent study project learning has a positive effect on self-directed learning ability and mathematical self-efficacy of mathematically gifted elementary students so that it could be meaningfully used as a teaching method for special education for the gifted at educational sites of independent study project learning.

The purpose of this study is to analyze the elementary pre-service teachers' preferred strategies while they solve problems which require number sense and to study a way to improve their number sense ability based on computational thinking. In a survey with 57 elementary pre-service teachers using the instrument consisting of two different number sense components, they preferred much more the rule-based strategies to the number sense-based strategies, which was consistent with the prior studies[13][14][20]. To change this situation, we present a way to improve their number sense ability by utilizing the analyzed results and the nine computational thinking components which were suggested by CSTA and ISTE(2011).

NCS (National Competency Standards) has emerged as an issue of great importance amongst Korean universities and corporations. Although previously used mostly for vocational education purposes at colleges, NCS is currently receiving an increasing amount of attention from 4-year universities as well. In the ever-evolving information economy, the basic workplace skills defined by NCS, which include soft skills such as communication skills, problem-solving skills, and interpersonal skills, have now become more important than specific technical skills. This study analyzes the correlation between the basic workplace skills of NCS with participation in Formula SAE activities, a common component of Capstone design courses across North America and Europe. Data are derived from site visits to Formula SAE competitions, competition-related documents drafted by student participants, and questionnaires administered to student participants at the Formula SAE Lincoln completion and at the Korea KSAE competition. From the study findings, we claim that the basic workplace skills of NCS are closely correlated to participation in Formula SAE activities. Through a survey designed to measure the degree to which Formula SAE activities can enhance an individual's NCS Basic Workplace Skills, we find that these activities overall improved NCS basic workplace skills averaging 4.0 points above in the Likert 5-point scale. For reference the mathematical skills, communication skills, and problem-solving skills displayed statistically significantly correlation with NCS but the remaining 7 skills did not show a statistically strong correlation with NCS comparatively.

In this study, the students' responses on the items of chemistry II in the College Scholastics Ability Test (CSAT) implemented for the past 3 years since 1999 was investigated. The number of applicants and mean score of chemistry II, average percent correct by contents and inquiry process, and the items with high and/or low percent correct are analysed and discussed. The percentage of applicants for natural science track is reduced each year. However, more than 25% of natural science track applied to chemistry II, which ranked second to biology II. The mean score of chemistry II was increased in 2001 along with those of other subjects. There is no difference in average percent correct either by contents or inquiry process. Students performed generally poor at solving test items relating to 'colligative properties of solution' such as 'boiling point elevation' or 'osmotic pressure', and very well at solving test items relating to 'reaction rates'. Educational implications are discussed.
