It is the purpose of the study to investigate how high school students understand the concept of carbon cycle according to their spatial perception ability. For this, a total of 30 male students and 33 female students, who belong to the science course of the 2nd grade at a general co-education high school located in a megalopolis of Korea and have finished the class of Earth Science I in the first semester, took part in the spatial perception ability test, and four male students and four female students were selected as members of two groups : one group of higher spatial perception ability and the other group of lower spatial perception ability, and they agreed to participate in the study and have got the test of the carbon cycle concept. The results are as followings. It was found that the students who had higher spatial perception ability recorded more scores in the carbon cycle concept, state change concept, and process concept at the factor of word association and the carbon cycle concept, state change and process concept at the factor of drawing than those who had lower spatial perception ability. Connecting link used in the systemic viewpoint was disclosed like this in the factor of causal map of those who had higher spatial perception ability : one student 2 and another one student 1 and the other two students 0 : and in the factor of drawing three students 1 and the other 0 ; But nothing was found in the factors of causal map and drawing of those who had lower spatial perception ability. In addition, it was also found that those students who had higher spatial perception ability, when compared with those students who had lower spatial perception ability, have understood the fact that carbon moves through the interaction of the earth system's lower parts; Three students, who showed higher spatial perception ability, had a low level of systemic thinking concept, and one student who had higher spatial perception ability and four students who had lower spatial perception ability did not have a systemic thinking concept.

The purpose of this study was to investigate misconceptions about plate tectonics which spread widely among freshmen at high school with drawing. For this, we chose 6 conceptions about plate tectonics by analysis of 7th curriculum and of 11 kinds of science textbooks. Questionnaire of drawing about plate tectonics were developed depending on them. Data was collected from 134 students who was freshmen at high school in Daegu. The result of this study was as follows. First, In structure of plate, 'upper mantle type' and 'crust type' misconceptions were more than half of the respondents. Second, In distribution of plate, 'cracked earthquake zone type' and 'earthquake frequency type' misconceptions were more than half of the respondents. Third, In formation of ocean ridge at oceanic crust- oceanic crust divergent plate boundary, 'divergence type' and 'collision type' misconceptions were more than half of the respondents. Fourth, In formation of mountain ridge at continental crust- continental crust convergent plate boundary, 'collision type' misconceptions were more than half of the respondents. Fifih, In formation of mountain ridge at oceanic crust- continental crust convergent plate boundary, 'subduction type' and 'fault type' misconceptions were more than half of the respondents. Sixth, In transform-fault at oceanic crust- oceanic crust transform-fault boundary, 'direction type' and 'section type' misconceptions were almost half of the respondents. In this study, students' drawings about plate tectonics showed similar misconceptions. This imply that drawing conceptions can be used by the strong evidence of misconceptions which spread widely among students. Furthermore, this study has a significance that this conclusion is useful to teachers as basic teaching-teaming materials of plate tectonics.

This study is to investigate how science and engineering integrated (SEI) lessons affect science-gifted students' perceptions about engineers and engineering practices. Twenty elementary science gifted students participate in this study, and they reflect what engineering practice means such as managing limited time and budget. The SEI lessons with 24 hours class time are used as an intervention. The main data are collected with 'engineer and engineering drawing test', open-ended questions and interviews about the drawing, and focus group interviews about the lessons. The transcribed interview data are analyzed using mixed methodology of quantitative (descriptive and paired t-test) and qualitative methods. The result shows that the SEI lessons have positive impacts on the science-gifted students' perceptions about engineers and engineering practices such as engineering design. After the lessons, the students perceive engineering and engineers in a desired way such as engineering as a social practice that many experts work collaboratively, the interaction between engineering and society, and the importance of ethics and social values in engineering practice.

The purpose of this study was to analyze children's perspectives on the role of male childcare teachers and children' s gender role concepts. According to the results, when it comes to how the children perceive the roles of the male childcare teacher, the children mostly saw the male childcare teacher as a person who teaches and in another case, they regarded him as someone who takes care of their daily life and who is willing to play games with them. On the other hand, the male childcare teacher's organizing of an environment, supporting tasks and working on a computer were perceived less by the children. In terms of the gender role concepts, the study confirmed that depending on the role performance of the male childcare teacher, the children in the male childcare teacher's class had better understanding than those children in the female childcare teacher's class. In order to secure the children's right to participate specified in the convention of the rights of the child, the study applied not only the interviews with the children but also their drawings to the analysis, and that was what led the study to an in-depth discussion on the perception of the children.

The purpose of this study is to present the mental model of young adolescents' media environment and the use and to provide several educational suggestions drawing on the revealed model. For this, the data were collected through 4 activities such as interview, picture drawings, word association experiment, and sentence completion task with ten 4-5th graders in elementary schools; they were qualitatively analyzed by 2 researchers. First, the meaning components driven by sentence completion task, word association experiment were totally 6 components: media device, connection(alienation), competence(provision), entertainment, adverse effects, ambilaterality. Second, the components of media mental model driven by pictures were 4 components: functions/competence, entertainment, conflict with paper books/sharing, harmfulness/ambilaterality. Third, the components from interview consisted of conflict between paper books and electronic media, communication-centeredness, fear(addiction) and users' qualification. Based on those results, careful examination in cyber talk, necessity of addiction prevention, active development of learning media and their balanced utilization with books, and healthful media literacy education and reinforcement of critical thinking were suggested.

복잡화된 국내 전력계통의 부하는 지속적으로 증가하는 반면 새로운 설비의 건설이 어렵고, 지역 편중화된 발전설비 때문에 선로 과부하, 고장전류, 전압안정도 문제가 발생하고 있다. 초고압 선로의 고장은 계통을 크게 불안정하게 하기 때문에 고장에 의해 영향을 받는 지역과 고장 후 계통의 조류변화를 분석하는 것은 중요하다. 현재 고장의 영향을 분석하기 위하여 조류계산을 통한 정적해석과 시모의를 통한 동적해석을 사용하다. 그리고 좀 더 큰 그림을 그리기 위하여 각종 전압안정도 지수를 사용한다. 하지만 일반적으로는 고장이후 계통에서 유효전력 흐름에 변화가 있는 지역을 분석하기 위해서는 번거로운 작업이 필요한 단점이 있다. Generation loass coefficient(GLC)는 transmmision loss factor(TLF)에서 발생한 문제를 분석하기 위해 제안되었고, load loss coefficient(LLC)는 각 부하에 전력을 공급하기 위해 발생하는 손실을 발전기별로 분석하기 위해 제안되었다. 위의 두 지수는 계통해석을 위해서 제안된 것은 아니었으나 전력조류추적기법을 기반으로하여 개발되었기 때문에 계통의 전력조류 흐름 변화에 대한 정보를 담고 있다는 특징이 있다. 본 논문에서는 GLC와 LLC의 개념에 대하여 설명하고 계통에서 발생하는 고장의 영향을 해석하는 관점에서 GLC와 LLC를 활용한다. 시뮬레이션 결과를 통해 GLC와 LLC지수로 계통에 대한 이해를 높이는 방안에 대하여 제안한다.

휴머노이드 로봇이 인간처럼 그림을 그리기 위해서는 순서를 가지는 드로잉 좌표 집합이 필요하다. 하지만 기존 영상 처리를 통한 윤곽선에서의 좌표 집합은 순서가 없고 로봇 암을 들어 올리는 좌표가 없다. 또한 불필요한 좌표가 다수 포함되어 있어서 효율적인 드로잉을 하기가 어려워 드로잉하는데 시간이 많이 걸린다. 따라서 본 논문에서는 3축으로 구성된 휴머노이드 로봇 암이 드로잉하기 위한 좌표 집합을 추출하는 알고리즘을 개발한다. 이를 구현하기 위해서는 로봇이 드로잉하기 위한 윤곽선 추출 알고리즘과 추출한 드로잉 좌표 집합에서 드로잉 순서와 로봇 암을 들어 올리는 점을 전체 좌표 리스트에 포함해야 한다. 제안하는 알고리즘이 추출하는 좌표 집합은 캠 영상으로부터 입력되는 컬러 이미지에서 이미지 프로세싱을 거친 윤곽선을 입력으로 하며, 추출한 좌표들의 순서와 로봇 암의 드로잉 시작점을 삽입함으로서 빠르고 효율적인 로봇 드로잉 좌표 집합 추출 알고리즘을 구현한다. 또한 제안하는 추출 알고리즘을 휴머노이드 로봇에 적용하여 실험하였으며, 좌표 추출 알고리즘의 정확성과 효율성을 비교하였다.
