The purpose of this study was to investigate the relationships between the ability of students' raising creative problems and academic achievement, science inquiry skills and creative personality of high school students. In order to evaluate the originality of problems, the present study used three methods: evaluation by frequency, teacher, and student. The results in this study turned out to be as follows: First, there was not much difference in the three methods. But familiar problems had the possibility of receiving higher marks. Second, the ability of students' raising creative problems was significantly correlated with academic achievement and creative personality, but there was no correlation with science inquiry skills. The subjects were divided into 2 groups by students' originality score. In the higher score group, the ability of students' raising creative problems was significantly correlated with creative personality, but in the lower score group, it was significantly correlated with academic achievement. Third, as for science inquiry skills and creative personality between two groups, there was no significant difference, whereas as for academic achievement(physics I, chemistry I), there was significant difference.

Purpose: The purpose of this study is to check the importance of higher level, sub higher level and lower alternative factor and the factor for relieved life and also check the comprehensive priority in executed "Safety and relieved life level improvement of apartment house residents by AHP analysis". Method: The safety management evaluation elements and alternatives have been arranged as hierarchical structure based on the preceding studies and the advice of experts for the maintenance and system of apartment house in this study. Study model is used for the survey of pair wise comparison composition targeting experts and AHP analysis method is used for alternative plan ranking, etc. Result: The response result of survey secured the consistency and it is confirmed that safety inspection for apartment house electricity facility is most important for higher level, safety inspection, detailed inspection and diagnosis evaluation are most important for sub higher level and plumbing equipments is most important for alternatives based on the analysis result of relative weight comparison for sub higher level and alternatives for final goal attainment of the study. Conclusion: Plumbing equipments, crime prevention safety and electrical safety are shown as top priority alternatives when observe it with expert manager's point of view for apartment house. It shows that securing the importance of living safety accident and deciding the level of relieved life can be improved are the alternatives of pre-prevention and management strengthening.

In this paper, we have proposed a circuit complexity optimization ILP algorithm of high-level synthesis system for new multiprocessor design. We have analyzed to the operator characteristics and structure of datapath in the most important high-level synthesis. We also introduced the concept of virtual operator for the scheduling of multi-cycle operations. Thus, we demonstrated the complexity to implement a multi-cycle operation of the operator, regardless of the type of operation that can be applied for commonly use in the ILP algorithm. We have achieved is that standard benchmark model for the scheduling of the 5th digital wave filter, it was exactly the same due to the existing datapath scheduling results.

Three conjectures as the criteria for developing differentiated science learning program for gifted elementary students were derived from the previous research report: 1) The students' reasons why certain educational programs were thought to be interesting or profitable could be classified into the 3 criteria; novelty, curiosity, participation. 2) Students used to think that the programs were interesting if at least anyone of the above 3 criteria is fulfilled. 3) They think, especially, that the programs were profitable if the curiosity criterion is satisfied. To check these conjectures, 47 students were investigated with a Likert type questionnair asking how much the given program is interesting and profitable to themselves after they finished a set of programs for gifted students.

This research purposes to find out the mathematical cognitive characteristics of Korean students and compare it with that of TIMSS 2011 high-achieving countries based on the Cognitive Diagnostic Theory. Based on framework and questions of TIMSS 2011, we select cognitive attributes. Using the data of 8th grade students' mathematical achievement in TIMSS 2011, we compare and analyze the top 15-countries students' cognitive traits. As a result, cognition domain of TIMSS 2011 is reclassified as 9 cognitive attributes. we could distinguish between easy attributes and difficult attributes that students in each country relatively think. Especially, Students of Korea relatively think Recall/Recognize, Compute, Classify/Measure and Represent are easy. On the other hand, relatively they have difficulties in Retrieve, Implement, and Generalize. Based on this research result, It is necessary to establish an educational measures for each attributes which students have difficulties.

본 연구에서는 오픈 도메인에서 동작할 수 있는 질의 응답 시스템(Open-domain Question Answer ing System)을 구현하고 영어권 TREC에 참가한 결과를 기술하였다. 정답 유형을 18개의 상위 노드를 갖는 계층구조로 분류하였고, 질문 처리에서는 LSP(Lexico-Semantic Pattern)으로 표현된 문법을 사용하여 질문의 정답 유형을 결정하고, lemma 형태와 WordNet 의미, stem 형태의 3가지 유형의 키워드로 구성된 질의를 생성한다. 이 질의를 바탕으로, 패시지 선택에서는 문서검색 엔진에 의해 검색된 문서들을 문장단위로 나눠 정수를 계산하고, 어휘체인(Lexical Chain)을 고려하여 인접한 문장을 결합하여 패시지를 구성하고 순위를 결정한다. 상위 랭크의 패시지를 대상으로, 정답 처리에서는 질문의 정답 유형에 따라 품사와 어휘, 의미 정보로 기술된 LSP 매칭과 AAO (Abbreviation-Appositive-Definition) 처리를 통해 정답을 추출하고 정수를 계산하여 순위를 결정한다. 구현된 시스템의 성능을 평가하기 위해 TREC10 QA Track의 main task의 질문들 중, 200개의 질문에 대해 TRIC 방식으로 자체 평가를 한 결과, MRR(Mean Reciprocal Rank)은 0.341로 TREC9의 상위 시스템들과 견줄 만한 성능을 보였다.

Although Korea students have been showed the top academic achievement in the international evaluation test for mathematics academic achievement, they have the low confidence, low interest and unwelcome attention about mathematics. In order to change student's affective aspects about mathematics, we introduced the problem based learning(PBL) method which is based on constructivist learning theories. By applying PBL to the middle and high class students, we investigated the effect of PBL on the students' academic achievement and mathematical attitudes. The study shows that there are the statistically significant differences between a control group and a comparison group both in academic achievement and mathematical attitudes.

기업 성공에 있어 인재 평가와 선발만큼 중요한 일을 찾기란 어렵다. 특히 상위 경영자 선발에서 주관적 판단에 의해 잘못된 인사결정이 이루어지는 경우에 그 손해는 크고 파장도 오래간다. 그래서 인재를 보는 안목을 높이기 위한 기업의 노력도 더욱 정교해지고 있다. 인재를 제대로 볼 수 있는 안목은 성공적 인사결정 나아가 기업 성공의 첫 걸음이다.
