최근 자신의 건강에 대한 관심이 고조되고 있는 반면, 현재 대부분 On-line에서 제공되는 진단 서비스 시스템은 질병 명을 이용하여 질병에 대한 처방이나 민간요법 등을 제시하고 있다. 이에 질병에 대해 전문지식이 부족한 일반인들이 이용하기에는 어려움이 있다. 따라서 본 논문에서는 On-line에서 퍼지 ART 알고리즘을 이용하여 사용자가 제시한 증상을 바탕으로 이미 학습되어진 질병의 증상과 비교하여 신경망을 통해 유사도가 높은 상위 3개의 질병을 도출한다. 도출된 질병에 대해 질병의 전체적인 증상과 동의보감에서 제시한 민간요법을 결과로 출력한다. 질병 데이터베이스는 서울대학교에서 교육용으로 출판한 가정의학(家庭醫學)을 기초로 동의보감과 한방의학백과서적을 통해 한의학 전문의의 검증을 거쳐 생성하였다. 그리고 본 시스템은 전문의의 상담시스템을 지원한다. 전문의의 상담시스템을 이용하여 자택 및 직장에서 편리하게 전문의의 진료와 소견을 받을 수 있도록 하였다. 전문의 상담 시스템은 전문의가 서버에 접속한 상태에서 사용자의 진로 신청으로 연결되며, 텍스트 데이터 및 기존의 진료기록이 있다면 이를 기반으로 전문의의 진단을 유도하도록 한다. 제안된 한방 자가 진단 시스템을 한의학 전문의가 분석한 결과 기존의 질병 진단 시스템 보다 일반성이 개선된 것을 확인하였다.

This study aims to investigate how the university educational programs about quadratic curves are operated in relation to the high school curriculum and what their effects may be, and the degree of understanding for the prospective and current teachers of the mathematical content knowledge about quadratic curves. To solve this research questions, we randomly selected three universities and one high school. Then we investigated the curricula of each department of mathematics education, compared them with the high school curricula, and conducted surveys of the professors' and students' conception on how much mathematical content knowledge they need to know about quadratic curves. The study resulted in the following conclusions. First, the curriculum on the subject of quadratic curves in the college of education is closely connected to the high school programs. This study's results showed that the college of education's curriculum includes a series of lectures regarding quadratic curves, and that within them, the mathematical content about quadratic curves associated with high school mathematics was thoroughly covered. Also, a large number of students who attended the lecture reported a significant increase in their understanding in regards to the quadratic curves. Second, it is strongly recommended to strengthen the connection between the college of education's curriculum and the actual high school education field. The prospective teachers think that there is a substantial need to learn about the quadratic curves because it is closely connected with the high school curriculum. But they find it challenging to put what they were taught into practical use in the high school education field, and feel that an improvement in this area is much needed. Third, it is necessary to promote, encourage and support the voluntary efforts to expand the range of the content knowledge in quadratic curves to cover the academic content associated with the high school mathematics.

This study was designed to identify the Attitude toward Engineering and Teacher Efficacy of pre-service teachers of engineering department, evaluate the validity of the difference and inquire into correlation between the Attitude toward Engineering and Teacher Efficacy. The study results are as follows. First, the Attitude toward Engineering of pre-service teachers of engineering department turned out to be 2.94, which is below average(3.00), and a bit lower figure than that of Teacher Efficacy(M=3.34). Second, there was no significant difference between the Attitude toward Engineering and Teacher Efficacy in a gender factor. In case of a major factor and grade variables, there was significant difference between Attitude toward Engineering and teaching efficacy of Teacher Efficacy. Third, as a result of analysis on the correlation between Attitude toward Engineering and Teacher Efficacy, it turned out that there was significant difference between in sub-area a few, which leads to conclusion that the attitude toward engineering and Teacher Efficacy will be gradually improved if educational institutes training pre-service teachers of engineering department operate teacher education courses considering major characteristics and learners' levels and give successful guidance to pre-service teachers. In addition, since the gender factor didn't make any significant difference between the attitude toward engineering and Teacher Efficacy, there is no need to develop and operate separate educational programs only for female or male pre-service teachers.

The purpose of this study is to explore how a high school science teacher (Teacher E) shifted her understanding and facilitation of scientific modeling through participation in a professional learning community (PLC) for over a year. Based on socially situated theory of learning, I focused on examining Teacher E's frames about scientific modeling from her social interactions. Teacher E participated in her school-based PLC over a year and collaborated with other science teachers, coaches, and researchers to improve science instruction. I qualitatively explored her participation in 6 full-day professional learning opportunities-studios-where the PLC members collectively planned, implemented, and debriefed modeling-based lessons. Especially, I focused on two Studios (Studio 2, 6) where Teacher E became the host teacher and implemented the lessons. I also examined her classroom teaching in those Studios. To understand how the PLC inquiry affected the shifts observed in Teacher E's understanding and practice, I explored how the inquiry evolved over the 6 Studios. Findings suggest that in Studio 2, Teacher E viewed students' role in scientific modeling as to fill out the worksheet with "correct" answers. Meanwhile, in Studio 6, she focused on helping students collaborate to construct explanatory models of phenomena using evidence. The PLC inquiry, focused on supporting students' construction of evidence-based explanations and collaboration in scientific modeling, seemed to promote the shifts observed in Teacher E's understanding and facilitation of scientific modeling. These findings can inform educational researchers and practitioners who aim to promote teachers' professional learning to support students' epistemic practices.

This study aimed to explore the relationship between Intelligent Robot Reacher(IRT)-student by examining the factors of their relationship perceived by middle school students. In doing so, we developed questionnaires based on the existing teacher-student relationship scale and conducted an online survey of 283 first graders in middle school. The collected date were analyzed using exploratory factor analyses with SPSS 23 and confirmatory factor analysis with Amos 21. The study findings identified four factors of IRT-student relationship namely "trust", "competence", "emotional exchange", and "tolerance". It is expected that the study can be used to discuss ways to enhance educationally significant interaction between students-IRT and teaching methods using intelligent robots(IRs). Also, the study will contribute to the understanding and development of various services using IRs. Based on the study finidngs, future studies should investigate the perception of various education stockholders (teachers, parets, etc) on IRT to elevate the Human-Robot Interaction in the education field.

The purpose of this study is to investigate trends in research studies on scientific argument and writing in Korea. 118 research studies published from 2004 to 2013 have been collected and analyzed. Many of the research studies focused on developing teaching strategies, analyzing contents of scientific argument and writing, and effects on student learning. More than half of the studies were conducted with elementary and middle school students while studies with pre-service, in-service teachers or high school students were relatively rare. Most research studies were conducted within regular school hour context and participants were given relevant information/education prior to argument and writing activities. Many research have analyzed student growth in scientific attitudes and we would suggest that further studies should investigate student growth in scientific concepts, scientific inquiry, and critical thinking. The structure and process of argument or the content and form of writing have been analyzed. The quality of argument and scientific concepts embedded in argument and writing should be investigated more in future researches.

In this study, we analyzed the characteristics of science academic achievement by multiple culture and North Korean migrant students types, percentage of correct answer and discrimination per items per groups, and contents domains using quantitative and qualitative method in the National Assessment of Educational Achievement (NAEA). As a results of analysis, the degree of science academic achievement of the students from multiple culture and North Korean is much lower than that of the general students. Also, the science academic achievement of the students from multiple culture and North Korean migrant is different from the general students. Especially, science academic achievement of the immigrated students and the North Korean migrant students was lowest. The analysis of items that the difference of the percentage of correct answer was large showed that the students from multiple culture and North Korean migrant were equally weak to it in all contents domains, but that the students from international marriage family born in country were weak in some areas. Therefore, the appropriate the teaching and learning method and the educational support is needed considering the group situation, so the educational implications are discussed.
