수학사탐구형 스토리텔링 교과서는 수학의 발달 과정에서 드러나는 발견의 논리를 교과서의 구성 원리와 내용 전개에 적용하는 것을 핵심으로 한다. 지식이 만들어져 가는 과정에 학생들이 흥미롭게 접근하도록 하여 수학이 인간의 필요에 의해 만들어진 지식이며, 인간의 창의적 사고로 인해 만들어지는 지식임을 인식하도록 할 수 있다. 뿐만 아니라, 학습 내용 이면에 숨어있는 수학적 통찰과 논리를 이해할 수 있게 하고 그것을 활용하여 새로운 수학적 지식을 만들어갈 수 있는 맥락을 제공할 수 있다. 본 연구는 수학사탐구형으로 개발된 '복소수와 이차방정식'단원의 개발 절차와 사례를 통해 스토리텔링 수학교과서의 가능성을 확인하고, 현장적용 가능성을 탐색하며 앞으로의 스토리텔링 교과서 개발에 있어 함의점을 제공한다.

무한(infinity)의 개념은 다른 과학적 개념들과 마찬가지로 진화의 역사를 지닌 개념이다. 우리는 여기에서 볼짜노(Bolzano)를 중심으로 논의를 전개하고자 하는데, 그는 형이상학적 관점에서가 아니라 수학적으로 실무한(actual infinity)을 수용한 최초의 인물로 여겨지기 때문이다. 볼짜노는 현대의 플라톤주의자들처럼 구성(construction)과정과는 무관하게 무한집합(infinite set)을 그 자체로 옹호하였는데, 이는 내포(comprehension)의 원리와 모든 개념에 대한 외연의 유일성(unicity)에 근거한다. 또한 그는 무한집합과 그 부분 사이에 1:1 대응(one-to-one correspondence)이 성립한다는 사실을 역설로 보지 않고 무한집합의 특징으로 인식했다. 그리스 시대에는 단 하나의 무한의 존재만 인정한 데 반해 그는 여러 종류의 무한의 존재를 인정했으며, 무한에 대한 논리적 정의를 수립하였다. 무한의 문제는 수학에서 점증하는 중요성을 지닌 구성적 방법(constructive method)의 시금석이 된다. 여기에서는 이에 대한 운을 떼는 것으로 그치고 본격적인 연구는 차후의 과제로 남겨두겠다.

This study analyzed the "research trends and the design processes" of the traditional patterns by examining the previous researches on the application of the traditional patterns. For this purpose, 96 studies which include master's and doctoral theses and research papers published in 8 Korean academic journals on Clothing from 2000 to 2010 were chosen. The findings of this study are as follows: First, when the previous researches on the application of the traditional patterns were classified according to their subject matter, they were classified into: research on clothing design, research on textile design, research on the design of cultural commodities, and research on mixed design. Second, the researches that were classified according to their subject matter were re-classified according to their year of publication. It was shown that the most active research was on the clothing design. The research on textile design, when compared with clothing design, alternated an increase and an decrease in every other year. Also, research on the design of cultural commodities were fewer than the research on clothing design or textile design although it is on the increase from 2008. Third, when classified according to the types of design, it was found that the designs based on a flora were most common. Fourth, in most cases, in the process of the designs, the designswere dispensed with the original form or were simplified. The choice of the tone of color, in most cases, were based on the concept selected by the designer. The most common method for the expression of the designs was based on the printing. Also, when it came to the presentation of the designs, the original work greatly outnumbered an imaginary work. Based on this study, it is hoped that there will be more active research on the application of the traditional designs which, in turn, can popularize the aesthetic beauty of Korea.

정보통신기술 및 교육패러다임 변화와 맞물려 이러닝을 활용한 직업교육훈련은 그동안 몇 차례 굵직한 변화를 겪어 왔다. 이러닝을 통한 직업능력개발의 트렌드는 학습의 모바일화, 짧은 콘텐츠의 증가, 학습경험제공의 민첩성과 현장 밀착성으로 요약 가능한 가운데, 본 연구는 이러닝을 통한 직업교육훈련 대상자들의 학습동기, 교육구성요소에 대한 중요성 인식, 학습 행태에 대한 조사연구를 실시하였다. 6개 훈련기관의 4,021명이 참여한 설문조사 응답을 분석한 결과, 자발적 자기계발 차원의 학습이 회사의 직무교육차원보다 높게 나타났고, 이러닝의 구성요소 중에서는 학습내용이 가장 중요한 것으로 나타나, 기존의 형식에 치우진 교육콘텐츠 개발이나 훈련평가가 보다 내용 중심적으로 변화해야함을 시사하였다. 학습 행태측면에서도 학습장소와 시간 활용이 보다 융통적으로 변화하였고, 시간을 정해놓지 않고 틈틈이 불규칙적으로, 특정시점에 몰아서 학습하는 추세를 확인할 수 있었다.

The purpose of this study is to find out the practical problems that 6th grade students are facing, how they perceive Practical Arts education and the praxis of Practical Arts education relating to the problems, and whether the content of Practical Arts curriculum is useful for solving practical problems of 6th grade students. The data used in this study are collected from questionnaires and include in-depth interviews in order to make up for the quantitative research. The major findings of this study were summarized as follows. 1. Elementary school students regarded Practical Arts education as the subject matter through which they learn skills of life. They thought it is useful to their present and future life and to nurture environment-friendly attitude. Furthermore, elementary school students perceive that the meaning of practice in Practical Arts education lies not in praxis as practical action, but in just practice as technical action. 2. According to the survey based on their perception and their practical problems, 66.9% of students answered the learning content of Practical Arts education is not useful in solving their problems. And only 33.4% of students answered the learning content of Practical Arts education is useful in solving their problems. Negative view was predominant among elementary school students. And the Practical Arts curriculum does not reflect much of the practical problems that 6th grade students face. Through these results, Practical Arts education turns out to be hardly related with students' life, though it is the subject matter of students' real life.

The thesis is to look for the method of applying process drama for bilingual education in multicultural society. This purpose can be resolved in three steps: first, to understand the purposes and functions of education changing to multicultural society; second, to survey the need of bilingual education conformed to its purposes and functions; last, to understand the theoretical background of process drama and seek the method of utilizing it to bilingual education. Recently, the Korean society is also changing to multicultural society with international marriages and immigrant workers. But they have difficulties in communicating in Korean, and their children have even the same. Under the basis of multiculturalism wanting peace and mutual respect between cultural groups, they have to be educated in equality. This is why the bilingual education is needed in our society. Process drama, a widely used term for educational drama in Britain, claims its effectiveness for L1, L2 and bilingual education, for the principal medium in drama is language and what drama delivers is related to meaningful human experiences. It is also supported on script theory of linguistic therapy. Kase-Polisini classifies the developmental process of education drama into 1) planning, 2) playing and 3) evaluation. This process can be applied to educational drama for language as well. Rather, educational drama applying to bilingual education has even more availability with the varieties of group organization and subject matter. Conclusively speaking, the group of dual language schools can be organized into 1) mother-tongued group, 2) mother-tongued and L2 group, 3) multilingual group, or 4) L3 group in educational drama activity, as the class generally consist of the mixed multilingual children. And the subject matter can deal with 1) the Korean society and culture, 2) the society and culture of the purposed language country, or 3) the society and culture of the third nations.

Amyloid positron emission tomography (PET) allows early and accurate diagnosis in suspected cases of Alzheimer's disease (AD) and contributes to future treatment plans. In the present study, a method of implementing a diagnostic system to distinguish ${\beta}$-Amyloid ($A{\beta}$) positive from $A{\beta}$ negative with objectiveness and accuracy was proposed using a machine learning approach, such as the Principal Component Analysis (PCA) and Support Vector Machine (SVM). $^{18}F$-Florbetaben (FBB) brain PET images were arranged in control and patients (total n = 176) with mild cognitive impairment and AD. An SVM was used to classify the slices of registered PET image using PET template, and a system was created to diagnose patients comprehensively from the output of the trained model. To compare the per-slice classification, the PCA-SVM model observing the whole brain (WB) region showed the highest performance (accuracy 92.38, specificity 92.87, sensitivity 92.87), followed by SVM with gray matter masking (GMM) (accuracy 92.22, specificity 92.13, sensitivity 92.28) for $A{\beta}$ positivity. To compare according to per-subject classification, the PCA-SVM with WB also showed the highest performance (accuracy 89.21, specificity 71.67, sensitivity 98.28), followed by PCA-SVM with GMM (accuracy 85.80, specificity 61.67, sensitivity 98.28) for $A{\beta}$ positivity. When comparing the area under curve (AUC), PCA-SVM with WB was the highest for per-slice classifiers (0.992), and the models except for SVM with WM were highest for the per-subject classifier (1.000). We can classify $^{18}F$-Florbetaben amyloid brain PET image for $A{\beta}$ positivity using PCA-SVM model, with no additional effects on GMM.
