  • The purpose of this study is to analyze the statistical literacy in elementary school students when they beginning inference. Picto-graphs provide statistical information and often data-related arguments they certainly qualify as objects for interpretation, for critical evaluation, and for discussion or communication of the conclusions presented. For research, the inference from pictograph task was designed and statistical literacy standards for evaluating the student's level was presented based on prior studies. Evaluating student's statistical literacy is meaningful in that it can check their current level. To know the student's current level can help them achieve a higher level of performance. The outcomes of this research indicate that pictograph can provide a basis for rich tasks displaying not only student's counting skills but also their appreciation of variation and uncertainty in prediction. Raising statistical thinking by students is an important goal in statistical education, and the experience of informal statistical reasoning can help with formal statistical reasoning that will be learned later. Therefore, the task about the inference from a pictograph, discussions on statistical learning of elementary school children are expected to present meaningful implications for statistical education.

  • This paper presents a text extraction method of camera based document image. It is more difficult to recognize camera based document image in comparison with scanner based image because of segmentation problem due to variable lighting condition and versatile fonts. Both document binarization and character extraction are important processes to recognize camera based document image. After converting color image into grey level image, gray level normalization is used to extract character region independent of lighting condition and background image. Local adaptive binarization method is then used to extract character from the background after the removal of noise. In this character extraction step, the information of the horizontal and vertical projection and the connected components is used to extract character line, word region and character region. To evaluate the proposed method, we have experimented with documents mixed Hangul, English, symbols and digits of the ETRI database. An encouraging binarization and character extraction results have been obtained.

The Effects of Storytelling Family Classes Using Picture Books on the Resilience and Parent-Child Relationship of Adolescents: Focusing on the Core Concepts of 'Relationship' and 'Safety' in Middle School Technology·Home Economics (그림책을 활용한 스토리텔링 가족 수업이 청소년의 회복탄력성과 부모자녀관계에 미치는 효과: 중학교 기술·가정 '관계'와 '안전'의 핵심개념을 중심으로)

  • The purpose of this study was to examine the effects of storytelling lessons using picture books on the resilience of adolescents and the parent-child relationships in the family unit of home economics subject in middle school. For this purpose, I selected picture books of five themes on family type, family relationship, family conflict, sexual violence, domestic violence, and family loss, and developed a teaching-learning process plan for 'Family class with picture book' using storytelling elements and techniques. The teaching-learning plan was applied to 194 middle school students in technology·home economics classes, and the learning effet was evaluated by comparing pre- and post-tests. As a result, the resilience level perceived by adolescents increased significantly after class, but no significant effect was found on self-expansion, which is a sub-factor of sociality. In the parent-child relationship of adolescents, the effect of instruction was shown in all areas, and the affectional bonds felt in the relationship with mother than with father showed higher increase. In the family unit of home economics, storytelling lesson through picture book seems to have a positive influence on the adolescents in their relationship with the family by bringing up the potential power in them to stand against the adversities they may face.

  • We presented a method of deep quiz cropping for automatic construction of quiz pool in online quiz systems. The method detects question boxes and sunda boxes in images captured from test papers by a deep learning-based object detector, and makes pairs of question box and sunda box by the box coupling. We applied the deep quiz cropping to images captured from test papers and achieved successful results.

  • This study is to distribute 5-year-old nuri curriculum science education contents in child picture books, and to investigate the categorical difference of science education contents between domestic and foreign picture books and among genres. The subjects were 219 picture books for children from 4 to 7, listed in which is published by Children's Book Study Group in 2012 and 2013. The research tool was from the article of 5-year-old nuri curriculum nature study, to analyze the contents of young children science education in the child picture books. Content analysis categories was set to two upper-categories and seven sub-categories. Research data were calculated in the analysis of the frequency and percentage of each item's category by the method of analysis conformity. In conclusion, first, in the analyzed result of the upper categories of young children science education contents in 219 picture books, the frequency appeared in order of 'Curious to maintain and expand', 'Learn living things and the natural environment', 'To explore the investigation technique', 'To enjoy the investigation technique', 'Utilize simple tools and machines', 'To search objects and materials', 'Learn natural phenomena'. Second, in the compared result between the domestic and foreign picture books and among genres, "scientific inquiry" is appeared more than "fostering an attitude of exploration".

  • 신경과 의사들은 실제 임상에서 환자들에게 대뇌피질감각의 이상 여부를 알기 위해 손바닥에 숫자나 문자를 쓰게 하여 알아 맞추게 하는 검사를 시행한다. 손바닥에 쓰여진 문자나 숫자를 인식하기 위해서는 몇 가지 단계의 인지과정이 필요할 것으로 생각된다. 첫번째로 손바닥에 닿는 감각을 인지해야 하고, 다음 단계로 이 감각들을 시공간적으로 통합하는 과정이 필요할 것이고, 이러한 정보들을 유지하면서 마지막 단계로 우리 머리 속에 있는 문자와 일치시키는 과정이 필요할 것이다. 본 연구에서는 위와 같은 가설 아래 각각에 해당할 수 있는 뇌영역을 밝히기 위해 기능적 뇌자기공명영상을 이용하였다. 손바닥의 일차적 감각을 인지하는 데는 일차감각영역이 활성화 되었고, 이차감각영역의 활성은 감각들의 시공간적 통합과 관련될 것으로 생각되었으며, 이것들을 유지하는 것은 작업기억의 하부구조인 시공간 그림판과 관련되는 영역이며, 문자를 일치시키는 과정은 브로카영역 부근의 활성과 관련되는 것으로 생각되었다. 위의 가설에 대한 추가검증 및 실제로 일어나는 인지과정에 대한 추가적인 연구가 필요할 것이다.

  • Activity materials in textbook could facilitate students' oriented self-help learning. The purpose of this paper is to find out characteristics of activity materials in the housing area of middle school Technology and Home Economics and teacher's perception of them. The data were collected from 253 middle school teachers who had ever taught the housing unit in any of 6 textbooks. The results showed that the number of activity materials were differed by the characteristics of the materials such as type of materials, feature of non sentence materials, and type of activity, depend on authors as well as textbooks. In general, teachers interests in the materials were higher than those of students even the trends of the interests were the same. Adequacy of activity contents and related knowledge of teachers were higher than adequacy of level. Teachers thought time and extra search beyond class were barrier to full the interests of students. Further research is suggested to find out whether higher interests in the materials are related to the higher activating rate of them.

  • 본 논문에서는 매개변수 없이 입력 문서 영상을 최대 동질 영역들로 분할한 다음, 각 동질 영역을 텍스트, 그림, 표 그리고 선으로 자동 분류하는 새로운 방법을 제안한다. 다단계 분석과 하향식 접근 방법을 사용하기 위하여 문서 영상을 피라미드 구조로 계층화하였으며, 어떤 영역을 분할할 지의 여부를 결정하기 위하여 그 영역의 주기성을 이용하여 판단하였다. 이러한 주기성 정보를 이용함으로써, 어떠한 매개변수 없이도 활자체 크기와 행간에 무관하게 텍스트 영역을 정확히 분석할 수 있었으며, 피라미드 구조를 만드는데 걸리는 시간이 질감 분석 접근방법보다 빠른 방법으로 설계되었다. Washington 대학의 문서 영상 데이터베이스를 이용한 실험 결과, 제안된 방법이 기존의 방법들보다 더 정확하게 문서 영상을 분할 및 분류할 수 있음을 확인할 수 있었다.
