  • Automatic segmentation of foreground text from the background in degraded document images is very much essential for the smooth reading of the document content and recognition tasks by machine. In this paper, we present a novel approach to the binarization of degraded document images. The proposed method uses a new local contrast feature extracted based on the stroke width of text. First, a pre-processing method is carried out for noise removal. Text boundary detection is then performed on the image constructed from the contrast feature. Then local estimation follows to extract text from the background. Finally, a refinement procedure is applied to the binarized image as a post-processing step to improve the quality of the final results. Experiments and comparisons of extracting text from degraded handwriting and machine-printed document image against some well-known binarization algorithms demonstrate the effectiveness of the proposed method.

  • A number of documents containing important and useful knowledge have been generated over time in the construction industry. Such text-based knowledge plays an important role in the construction industry for decision-making and business strategy development by being used as best practice for upcoming projects, delivering lessons learned for better risk management and project control. Thus, practical and usable knowledge creation from construction documents is necessary to improve business efficiency. This study proposes a knowledge creating system from construction documents using text mining and the design comprises three main steps - text mining preprocessing, weight calculation of each term, and visualization. A system prototype was developed as a pilot study of the system design. This study is significant because it validates a knowledge creating system design based on text mining and visualization functionality through the developed system prototype. Automated visualization was found to significantly reduce unnecessary time consumption and energy for processing existing data and reading a range of documents to get to their core, and helped the system to provide an insight into the construction industry.

  • Nowadays, reading text from screens is prevailing in everyday life. The advent of mobile information devices such as a cellular phone, PDA, and e-book reader facilitates us to enjoy various text-based contents any time and anywhere. Most studies comparing screen and paper readability show that screens are less readable than paper. Furthermore, the decrease of line length and number of lines that can be displayed on the screen of mobile information devices deteriorate text readability. This study investigated parameters affecting text readability on small screens and designed a new text layout to improve readability. We suggested a diagonally splitted layout of rectangular column, which is supposed to facilitate eye movement to trace text flow with ease. The experiment comparing readability between a traditional rectangular column and a diagonally splitted column was conducted. The result of experiment revealed that there is no significant difference between the two text layouts in terms of subjective satisfaction of reading task and a level of comprehension. However, in the screen size of $4000mm^2\;and\;8000mm^2$, reading speed was increased 18.9% and 34.0% respectively from a traditional rectangular column to a diagonally splitted column. We conducted a consecutive experiment to scrutinize the cause that improved the performance in readability task remarkably. The readability of text in a traditional rectangular column was compared with a left triangular column and a right triangular column in the condition of $4000mm^2/3:1$ ratio screen. The performance measurements revealed that participants read 21.1% and 67.6% faster respectively with the left triangular column and right triangular column than with the rectangular column. In consequence, the improvement of readability in the diagonally splitted column was attributed mainly to the increase of reading speed in the right triangular column. This research verified that the diagonally splitted column improve text readability on a small screen and this result is expected to make a contribution to designing an efficient text layout for mobile information devices

  • This paper argues that what Edgar Allan Poe pursues in ;The Man of the Crowd" (1840) is not a story that can be told but an active reading that must be mediated. It is not only because the subject of the pursuit, the secret of the flaneur, remains veiled until the end, but also because the story proves itself to be a reading of various kinds of other texts: that is, the contemporary urban texts as well as the city itself. Although the 'man of the crowd' and his double (i.e. the narrator) embrace the figure of a modern flaneur, it is highly questionable whether the image of flaneur in the story fully qualifies itself as that of an ideal stroller, who can represent the free spirit of a detached collector. Rather, the narrator's flaneur reflects a panoptic perspective, systematically hierarchizing the constituents of the city. Still, it should be noted that ;The Man of the Crowd" raises questions about the idea of creation and appropriation, observation and originality, and reading and storytelling by ascertaining the impossibility of reading and through assimilating to the contemporary texts not without subtle acknowledgement. In short, this novella tries a new way of storytelling, of which meaning is not to be found in creation but to be mediated in modern experiences.

  • Hypertext raises question to general assumptions about our conventional conceptions of education. In this essay, three kinds of learning-models are presented by the application of "writing" hypertext literature to the English education of the elementary school. These models, which I call the "scene-centered" system, give knowledge to learners in non-linear, non-sequential structure. The term "scene" is a single concept or idea composed of a single sub-text, which is to be made by the group of students. This system is focused on the collaborative composition of students. Students, by generating sub-texts and connecting texts, perform the educational activities to expand the source text. The "scene-centered" system is, to put it into a Barte's term, a "writerly text." But in order to "write," "reading" should be accompanied. So, this system is a learning model in which writing and reading are carried on simultaneously. In all the process, students play a role of multi-user, with three access rights: read, write, and annotate. So, students making use of hypertext systems will act as reader-authors. And teachers will take the new role in collaborative writing environment. No longer the central authoritarian evaluator, they will become consultants, co-writers, coaches of their students.

  • Objective: This study investigates user performance and user perceptions of dynamic Chinese text displays (Leading display and RSVP display) when users search for target information. Background: Today, information searching with dynamic displays is widely used in TV programs, on Internet advertisements, for traffic information systems, and more. Method: A human factors experiment was conducted to compare both displays. Eighteen subjects participated in evaluating two simulated interfaces for the leading display and the RSVP display. Results: The results show that the leading display was better in terms of search time and certain subjective measurements (Easiness, frustration, anxiety). The latter results are consistent with the conclusions of other research efforts showing that dynamic displays are more effective and efficient when reading information. Conclusion: The leading display is more useful for Chinese users in terms of both information searching and information reading. Application: This study helps design dynamic displays written in Chinese texts.

  • Objective: The aim of this study was to investigate postural control strategies on smart phone use during gait in over 50-year-old adults. Method: 8 elderly subjects (age: $55.5{\pm}3.29yrs$, height: $159.75{\pm}4.20cm$, weight: $62.87{\pm}8.44kg$) and 10 young subjects (age: $23.8{\pm}3.19yrs$, height: $158.8{\pm}5.97cm$, weight: $53.6{\pm}5.6kg$) participated in the study. They walked at a comfortable pace in a gaitway of ~8 m while: 1) reading text on a smart phone, 2) typing text on a smart phone, or 3) walking without the use of a phone. Gait parameters and kinematic data were evaluated using a three-dimensional movement analysis system. Results: The participants read or wrote text messages they walked with: slower speed; lesser stride length and step width; greater flexion range of motion of the head; more flexion of the thorax in comparison with normal walking. Conclusion: Texting or reading message on a smart phone while walking may pose an additional risk to pedestrians' safety.

  • This study analyzed the reading materials presented in the existing 'Experiment Observation' targeting 31 elementary school students and conducted a preliminary investigation to examine the cause which makes the science reading materials of elementary school difficult to read. Also, on the basis of a preliminary investigation, this study developed the reading materials on science. After that, by examining the degree of understanding about existing reading materials on 'Experiment Observation' targeting 55 students of elementary schools and the newly developed reading materials targeting 44 students of elementary schools, the study proved its effect. As the result of the study, the causes for which students felt difficulty in reading were as follows: the scientific or non-scientific terms were explained by using more higher levels of Chinese characters compared to the levels of students; the scientific terms never treated in the classroom were used in the reading materials without any explanation; the overall structure of existing reading materials was distracted and listed the fragments of information, and the sentences were described complicatedly; the contents of a text and the photo materials were not connected functionally. In addition, the newly developed science reading materials were preferred by students because more various methods were devised, such as more systematic structure, arrangements of simpler sentence structure, additional explanation of scientific terms, divisions of paragraphs and postscript and their understanding was found to be improved.

  • The purpose of this study is to develop a model of attitude toward reading. For that the concept and factors of reading attitude were examined and the preceding reading attitude models were critically studied to propose the new reading attitude model. The reading attitude model is consisted of three component named reading environment domain, reader domain and reading domain. The results of the development of a model of attitude toward reading are as follows. First, This study proposed a theoretical framework that can check and measure the reading attitude in various aspects by dividing reading attitudes into cognition, affect and intention factors. Second, It reinforced the logicality on the construct of reading attitude by dividing behavioral factor of reading attitude into the intention and the behavior. Third, This Model reflected the importance of book with text by specifying physical books and reading a book in the model. Fourth, this model theoretically proposes the potential for change of reading attitude and behavior by suggesting cognitive and affective schema from reading experience. Fifth, the developed reading attitude model helps to understand the form and process of reading attitude by presenting impact of reading environment and stimulation derived from reading environment on reader and reader's reading behavior and affective relation on feedback.

  • The purpose of this study is to structure the system of reading strategy contents and seek a subject linkage method through using it. In order to establish the contents of reading strategy, the 2015 Korean High School Revised National Curriculum's contents system and advanced research were looked at. From that curricula, text areas(the types and fields, meaning structure) and cognitive strategy(reading methods and skills) are deduced and categorized. In addition to reading techniques reorganized by referring to worksheets of advanced researches, the system of reading strategy contents was made. As the result of applying it to the learning activities of "he Integrated Society" and "he Integrated Science" a subject linkage to learn the learning contents proposed providing a variety of reading materials related to the subject and running extended reading programs.
