본 논문에서는 두 대의 카메라로부터 입력받은 인간의 신체와 같은 관절체의 움직임을 Color Marker의 색상 특성을 이용하여 3차원 공간 정보를 인식하는 방법에 관해 기술한다. 이 방법은 인체에 물리적인 장치를 하지 않고 단순히 영상정보만을 이용하여 3차원 정보를 구하였다. 보다 정확한 인체의 특징점을 구하기 위해 환 논문에서는 신체의 관절각에 칼라 마커를 부착하고 칼라 마커틀을 세그먼트하여 관절각의 2차원 정보를 구한 다음 스테레오 기하(Stereo Geometry)를 이용하여 3차원 정보를 계산하고 가상 공간상에서 인간의 움직임을 추적하는 방법을 제안한다. 제안하는 방법은 제스쳐 인식과 3차원 Virtual Reality 인터페이스 시스템 구성 등에 사용될 수 있다.

This study aims to suggest the conceptual framework for the Nature of Technology (NOT) by examining the current researches regarding the NOT in science and technology education and to analyze the conceptions of experts in science, technology, and engineering fields based on the framework of NOT. The NOT conceptual framework developed in the study consisted of the six domains of NOT, which are 1. Technology as artifacts, 2. Technology as knowledge, 3. Technology as practice, 4. Technology as system, 5. The role of technology in society, and 6. History of technology. Also, the results of analyzing the conceptions for the 30 experts in science, technology, and engineering fields emphasize on the three domains of the 3. Technology as practice, 4. Technology as system, and 5. The role of technology in society among the 6 domains of the framework of the six domains of the NOT framework. This findings are different from the results of previous researches conducted in science and technology education for exploring the conceptions of NOT in the POV of the public and students. As such, the results show that while the public and students possess naive ideas on NOT only focusing on the technology as products and tools, experts in science, technology, and engineering fields possess the authentic views of the NOT reflecting the complex and abstract concepts of technology in terms of the perspectives of philosophy of technology.

The college of education should support pre-service teachers to learn knowledge of their major and develop the ability of presenting or teaching the knowledge. The pre-service teachers may have many opportunities of presentations to develop the ability of teaching. Some college of education provide such opportunities in the 'seminar' course. In this study we investigated the pre-service teachers' perceptions on the seminar where they present contents of their major, developed the framework to analyze and evaluated the seminar presentation ability, and explored the change of presentation ability through a case study. Pre-service teachers perceived that from the seminar they could develop the presentation skill and understand the scientific contents more deeply. However they pointed out the difficulty of understanding others' presentations, discussing on the contents and interpreting the English paper. We developed the presentation analysis framework including the evaluation elements, the evaluation items, and the evaluation methods according to the progress of a seminar presentation. Using this framework we evaluated and compared the development of seminar presentation ability of a per-service teacher both quantitatively and qualitatively. We discussed the educational implication of this study such as the suggestion for the effective management of a seminar and the usage of the presentation analysis framework.

This paper embodies the rating recognition system of broadcast program which can automatically acknowledge the broadcast pictures indicating the harmfulness rating, so prevent children from watching TV. This experiment was progressed as the course of extracting featured patterns (standard number patterns) and the proper patterns owned only by the concerned numbers from the numbers of standard font used by broadcasters, and comparing these patterns with input pictures and arranging them. The recognition rate of x-rating was remarkably high as a result of this experiment.

우리 소설이 냉전체제의 닫힌 틀에서 벗어나게 되는 것은 제3세계적 인식의 확대.심화에 말미암는다. 월남전이 우리 소설의 중요영역으로 편입되는 핵심근거는 바로 그것이다. 6.25전쟁소설이란 영역이 있듯이 '월남전소설'이란 영역도 설정이 가능할 정도로 월남전을 다룬 소설은 뜻밖에도 많다. 대표적인 작품을 통해 그 대강을 살펴본다.

집합식 교육의 대안으로서 최근 기업 환경에서 인식되고 있는 인재육성 방법이 바로 e-러닝이다. 이는 비즈니스와 정보기술 분야에서 나타나던 디지털 혁명의 영향력이 교육에서도 그 반향을 일으킨 것으로써, 교육의 틀 자체를 급속한 변화에 대처할 수 있도록 바꾸어 놓은 것이다. 과거처럼 획일적인 교육방법과 지식을 제공하는 대신에, e-러닝은 학습자가 다양한 학습환경 및 자원에 자유롭게 접근할 수 있게 함으로써 새로운 학습 경험을 할 수 있는 기회를 제공한다.

This study aims to design a framework for analyzing group argumentation in terms of participants' interaction. Regarding the current group argumentation setting as argumentation on socio-scientific issues within participants who have had limited experience on group argumentation, the analytical framework was designed to explain (1) what was each participant's role on group argumentation, (2) how these roles were changed within each time of argumentation, and (3) how the patterns of interaction were changed through seven times of a series of argumentation on socio-scientific issues. Based on the literature review on analytical framework of argumentation in science education including the works on the structure of argumentation, the discourse formation through interaction, and the linguistic approach on participants' interaction, the current research framework was built. Showing the results of applying the designed framework on group argumentation as an example, strength of using the current designed framework was discussed.

본 논문에서는 조명에 변화에 강인하고 기존의 퍼지 색상 필터보다 정확하고 빠른 얼굴 감지 알고리즘 이용하여 얼굴을 인식하고 얼굴로부터 특징점(눈, 눈썹, 입)틀을 추출하고 추출된 특징점을 이용하여 감성을 판별하는 방법을 제안한다. 향상된 얼굴 인식 기술이란 퍼지 색상 필터의 단점이 영상의 크기와 성능에 따라 처리속도가 느려지는 것을 보완하기 위하여 최소한의 규칙을 사용하여 얼굴 후보 영역을 선별 적용하여 얼굴영역을 추출하는 기법을 말한다. 이렇게 추출된 얼굴영역에서 감정이 변화 할 때 가장 두드러지게 변화를 나타내는 눈, 눈썹 그리고 입의 특징점을 이용하여 감성을 분류한다.

By using a combination of different feature sets extracted from input character patterns, we can improve the character recognition system performance. To reduce the dimensionality of the combined feature vector, we conduct the feature selection. This paper proposes a general framework for the feature combination and selection for character recognition problems. It also presents a specific design for the handwritten numeral recognition. Tn the design, DDD and AGD feature sets are extracted from handwritten numeral patterns, and a genetic algorithm is used for the feature selection. Experimental result showed a significant accuracy improvement by about 0.7% for the CENPARMI handwrittennumeral database.
