This paper describes the development and implementation of a algorithm to decompose word images from image regions mixed text/graphics in document images using statistical analyses. To decompose word images from image regions, the character components need to be separated from graphic components. For this process, we propose a method to separate them with an analysis of box-plot using a statistics of structural components. An accuracy of this method is not sensitive to the changes of images because the criterion of separation is defined by the statistics of components. And then the character regions are determined by analyzing a local crowdedness of the separated character components. finally, we devide the character regions into text lines and word images using projection profile analysis, gap clustering, special symbol detection, etc. The proposed system could reduce the influence resulted from the changes of images because it uses the criterion based on the statistics of image regions. Also, we made an experiment with the proposed method in document image processing system for keyword spotting and showed the necessity of studying for the proposed method.

The purpose of this study is to propose criteria for selecting picture books as various reading education materials for middle school students and to check whether it can be applied to book selection. First, identified the educational value of picture books as reading materials and the criteria for selecting picture books by academic field through previous studies. After integrating the commonalities of various picture book selection criteria presented in previous studies by categorizing them into illustrations, text, and other categories. And it devised selection criteria that can be applied after selecting middle school students as readers. Based on the unified picture book selection criteria, a survey was conducted to ask in-service librarians about the main criteria to consider when selecting picture books for middle school students, and intensive interviews were conducted with experts who have experience in picture book education. As a result, the picture book selection criteria from previous studies were revised and supplemented with two criteria related to text, four criteria related to pictures, and five other criteria, and presented as picture book selection criteria for middle school students. To verify the practicality of the picture book selection criteria, it checked the applicability of each category of criteria to picture books recommended by the Children's Book Research Society (ages 13 and older). Out of 22 picture books for middle school students, 15 books could be applied to all categories of the selection criteria, showing significant practicality.

Document image layout analysis contains the process to segment document image into detailed regions and the process to classify the segmented regions into text, picture, table or etc. In the region classification process, the size of a region, the density of black pixels, and the complexity of pixel distribution are the bases of region classification. But in case of picture, the ranges of these bases are so wide that it's difficult to decide the classification threshold between picture and others. As a result, the picture has a higher region classification error than others. In this paper, we propose document image layout analysis method which has a better performance for the picture and text region classification than that of previous methods including commercial softwares. In the picture and text region classification, median filter is used in order to reduce the influence of the size of a region, the density of black pixels, and the complexity of pixel distribution. Futhermore the classification error is corrected by the use of region expanding filter and constrained conditions.

The purpose of this study was to analyze the type of endpapers in Korean picturebooks that won the Bologna Ragazzi Award. The endpapers were classified by three standards: identities between front endpapers and back endpapers, type of arts, and type of contents. As results, picturebooks with identities between front endpapers and back endpapers were slightly more than ones with unidentities. Most of art types were illustrated, followed by patterned and plain. In addition, the peritextual contents were found to be the most frequently used content type in endpapers. The results showed that the most endpapers of the Korean picturebooks that won the Bologna Ragazzi Award were related to the text contents, which suggests the important roles of endpapers in picturebook activities.

A word cloud is a visualization of word frequency in a given text. The importance of each word is shown in font size or color. This plot is useful for quickly perceiving the most prominent words and for locating a word alphabetically to determine its relative prominence. With dynamic graphics, we can find the changing pattern of prominent words and their frequencies according to the changing selection of chapters in a given text. We can define the word frequency matrix. In this matrix, rows are chapters in text and columns are ranks corresponding to word frequency about the words in the text. We can draw the word frequency matrix plot with this matrix. Dynamic graphic can indicate the changing pattern of the word frequency matrix according to the changing selection of the range of ranks of words. We execute an English Bible text visualization using word clouds and dynamic graphics technology.

This paper deals with the improvement of the synthesized speech quality and naturality in the Korean TTS(Text-to-Speech) system. We had extracted the parameters(table2) such as its amplitude, duration and pitch period in a syllable through the analysis of speech waveforms(table1) in the time domain and synthesized syllables using them. To the frequencies of the Korean pronunciation large vocabulary dictionary we had synthesized speeches selected 229 syllables such as V types are 19, CV types are 80. VC types are 30 and CVC types are 100. According to the 4 Korean syllable types from the data format dictionary(table3) we had tested each 15 syllables with the objective MOS(Mean Opinion Score) evaluation method about the 4 items i.e., intelligibility, clearness, loudness, and naturality after selecting random group without the knowledge of them. As the results of experiments the qualities of them are very clear and we can control the prosodic elements such as durations, accents and pitch periods (fig9, 10, 11, 12).

Children's Picture Book is the literature with which children face for the first time as a form of close harmony between text and picture. The picture book shows what is happening and also what may happen mn the children's surroundings and takes great Influence on their creativity, thinking ability, emotion, and Intellectual ability by delivering affluent story through the pictures. The color expressed in the children's picture book is as much important as other formative elements such as shape and texture, and the expression of color on the basis of color emotion is much more Important In that It appeals to the children's feeling. The color which is expressed through the illustration of children's picture book conveys distinctly the motion and feeling of characters who are expressed un the picture book as well as distinction of theme and background and expresses persuasively the whole process of plot and atmosphere so that it might convey various emotions such as delight, sorrow, pleasure, wonder, and fear to children. This thesis alms at analyzing various effects of color contrast, process of color, hue variation, and use of color according to the atmosphere of each cut and the process of plot by selecting the children's picture books which were published abroad and home on the basis of color concept, emotion, and image association which children feel In order to Investigate and analyze the symbolism of color and emotional effect expressed through the illustration of children's picture book, and presenting a direction of color use to produce high-level children's picture book with illustrators individuality and artistry.

The multivariate empirical distribution function could be defined when its distribution function can be estimated. It is known that bivariate empirical distribution functions could be visualized by using Step plot and Quantile plot. In this paper, the multivariate empirical distribution plot is proposed to represent the multivariate empirical distribution function on the unit square. Based on many kinds of empirical distribution plots corresponding to various multivariate normal distributions and other specific distributions, it is found that the empirical distribution plot also depends sensitively on its distribution function and correlation coefficients. Hence, we could suggest five goodness-of-fit test statistics. These critical values are obtained by Monte Carlo simulation. We explore that these critical values are not much different from those in text books. Therefore, we may conclude that the proposed test statistics in this work would be used with known critical values with ease.

Academic interest in the educational value of picturebooks for children and the narrative importance of peritexts have been increased. This study was conducted with the purpose of presenting the components for analyzing the picturebook peritext. To this end, the components of the peritext used in 11 previous studies that analyzed the peritext of picturebooks were comprehensively reviewed. Looking at the results of the study, the components used in previous studies were largely categorized into four categories, and according to the characteristics of the components within each category, they were classified into 'basic information', 'physical elements', 'positional elements', and 'content elements.' The first category, 'basic information,' includes the title, authors' name, publication information, award information, and dedication/acknowledgment, laudatory comment. The second category, 'physical elements,' includes the format, book binding, and quality of material. The third category, 'positional elements,' includes cover(front cover, back cover, spine), endpaper, title page, copyright page, dust jacket and belly band. The fourth category, 'content elements,' includes text, illustration, typography, layout and page shape. Through the results of this study, it is expected that research on the analysis and utilization of various picturebooks will be activated.
