본 논문에서는 새로운 문자 분할 알고리즘을 제안한다. 고전적인 문자 분할 알고리즘은 학술적인 문서영상과 같이 단순한 구조를 가진 문서영상을 대상으로 하여 좋은 성능을 보였지만 다양한 문자 크기와 색상, 그림, 복잡한 배경 등으로 구성된 문서영상에서는 좋지 못한 성능을 보인다. 최근에 제안고 있는 방법들은 복잡한 문서영상에서도 좋은 성능을 보이도록 다양한 기법들을 적용하여 우수한 성능을 보이고 있지만, 대부분의 방법들이 영상을 일정한 크기의 블록으로 나누어 문자분할을 하기 때문에 세밀한 부분에서는 성능이 어느 정도 한계를 보인다. 따라서 본 논문에서는 블록의 크기에 제한을 갖지 않는 새로운 방법으로서, watershed 알고리즘을 이용한 문자분할 방법을 제시한다. 구체적으로, watershed 알고리즘을 이용하여 문서영상의 구조(docstrum)를 파악하고 이를 기반으로 문자를 분할한다. 제안하는 방법은 크게 엣지 검출, distance transform, watershed 알고리즘을 이용한 docstrum 분석, 문자 분할의 네 단계를 거친다. 실험 결과 블록에 기반한 기존의 방법들이 놓치는 세밀한 부분에서도 제안된 알고리즘은 올바른 분할결과를 얻을 수 있음을 확인하였다.

Digital talking books have been developed to enhance reading experiences for reading-disabled people. In the existing digital talking books, however, it is difficult to read special contents such as math expressions, images, etc. In this paper, we define reading rules for Contents MathML. Based on this rules, we implemented a program for reading the mathematical contents of Contents MathML, using XSLT. We conducted a confirm test to prove the accuracy of the program, and an usability test to measure understanding of reading text of math expressions.

최근 학술정보서비스는 논문의 메타정보 중심에서 논문 원문의 전문정보(Full-text)로 구축 및 서비스 범위가 확장되고 있다. 학술지 논문의 전문정보를 기술하기 위해 해외출판사들을 중심으로 다양한 XML 양식이 개발되었으나, 2012년에 국제표준으로 제정된 JATS(Journal article tag suite)가 국내에서 폭넓게 사용되고 있다. 국내 과학기술분야 정보서비스의 대표기관인 KISTI는 2014년부터 JATS 기반으로 학술논문 XML을 구축하여 서비스하고 있다. 아울러 KISTI는 2007년부터 국내 학술논문의 국제적 유통 활성화를 위하여 논문에 DOI를 부여하고 CrossRef에 기탁해오고 있다. 향후, KISTI가 주관하는 Korea DOI Center를 통해 논문 DOI 뿐만 아니라 논문의 비텍스트(표, 그림)정보까지 모두 DOI를 부여하고 서비스에 반영할 계획이다. 이를 위해, 현재까지 구축된 JATS XML에 대한 구성요소를 분석하고 비텍스트정보의 DOI 등록방법 및 활용방안에 대해 살펴본다.

The paradigm of communication is changing by the generalization of mobile computers and the extension of network service. In the mobile messenger communication, people are increasingly using character emoticons to substitute linear text. This means that the character emoticons are functioning as narrative characters so that they are becoming the nonlinear techno-code, which can substitute for the alphabet code. As Vil$\acute{e}$m Flusser said, the post-modern communication is arrived. In this kind of communication, storytelling with character emoticons are effective enough to tell various stories. In this point of view, this paper tries to prove the functions of character emoticons and suggests the classification of the character emoticon series. This paper also structures the post-modern communication model as a new paradigm of visual communication.

This paper proposes an efficient algorithm which recognizes the mixed document image consisting of the images, texts, tables, and straight lines. This system is composed of three steps. The first step is the detection of rotation angle for complementing skewed images, the second is detection of erasing an unnecessary background region and last is the classification of each component included in document images. This algorithm performs preprocessing of detecting rotation angles and correcting documents based on the detected rotation angles in order to minimize the error rate by skewness of the documentation. We detected the rotation angie using only horizontal and vertical components in document images and minimized calculation time by erasing unnecessary background region in the detecting process of component of document. In the next step, we classify various components such as image, text, table and line area included in document images. we applied this method to various document images in order to evaluate the performance of document recognition system and show the successful experimental results.

The purpose of this study was to investigate the effects of a writing program and the type of picture book used on the early stages of writing and creative writing in young children. The different stages of writing amongst young children was divided into an early stage of writing for pre-schoolers and creative writing for spontaneous expression and problem solving. The subjects comprised 36 children aged 5 from a child daycare center in Seoul. Among the KISE-BAAT and Creative tests, the writing test and creative writing test were used. The early stage of writing and creative writing were both analyzed by means of both ANCOVA and T-test. Firstly, in the subscale of the early stage of writing(ability to mark, use vocabulary, create sentences and text construction), the early stage writing of the experiment group scored higher than that of the comparison group. Secondly, in terms of the type of picture books, the group using informational picture books had greater effects on the early stage of writing than the group using narrative picture books. Thirdly, the writing program itself had a positive effect on creative writing. In the subscale of creative writing (fluency, flexibility, novelty), the group using informational picture books made greater progress in fluency and novelty than the group using narrative picture books.

The 2015 revised information curriculum emphasizes the ability to solve problems in real life based on the basic concepts, principles and techniques of computer science. How the contents of textbooks are designed is an important issue in terms of achievement of educational goals and whether contents can be easily and clearly communicated. The purpose of this study is to analyze the concept presentation method presented in middle school informatics textbooks by three types of text- centered type, picture-centered type, and case-centered type- to analyze differences in understanding according to individual variables (sex, subject preference). Analysis results found the figure-centered type showed the highest degree of comprehension among students, and the preference of contents design type and the difference of understanding according to sex did not show significant differences. According to the preferred subjects, understanding of the content design types were found to be significantly different according to preferred subjects.

Much of our lives are closely related to artificial intelligence, and society is changing more rapidly. Reflecting this era, the need for artificial intelligence education has emerged and various learning methods have been proposed, but guidance on artificial intelligence teaching and learning activities for lower grades elementary school students is insufficient. Therefore, in this study, the data collection education program for the lower grades of elementary school was developed based on the contents standards of the Korea Foundation for the Advancement of Science & Creativity. Focusing on the principles of artificial intelligence and the detailed data area of the utilization area, the focus was on expressing numbers and letters in various ways, such as colors and pictures, and finding various types of data in life to learn the principles of artificial intelligence. Through this program, it is expected that lower-grade elementary school students will be able to understand the importance of data collection in artificial intelligence through the process of knowing about data and collecting sound, picture, and text data.

The aim of this study was to find out the possibilities of humanistic education through text analysis of the picture books of Korean fairy tales dealing with poverty and to discuss the educational implications. For this, the two researchers drew the literal roles of poverty and property in the common narrative structure of seven subject books and discussed the humanistic educational implications. The results are as follows. Firstly, the poverty of a main character was related to good personalities rather than negative personalities such as indolent disposition and formed affirmative values. Secondly, divine existence or animal helpers offered property to the good man in a unrealistic manner so that it emphasized the meaning of reward on their good nature. Thirdly, the bad character of wicked men following the good men was focussed on and their greed for property was the evidence of their wickedness. Most of them were punished because of the wicked motive so that it apparently highlighted the lesson of the good triumphing over the evil by the binary opposition structure. Fourthly, all the fairy tales made the characters treated based on the each personality: punishment or reward. However, the reward was usually property so that the property itself was depicted as a kind of blessings. Based on those findings, some humanistic educational implications were discussed.
