Existing character recognition algorithm recognize characters in simple conditional. It has the disadvantage that recognition rates often drop drastically when input document image has low quality, rotated text, various font or size text because of external noise or data loss. In this paper, proposes the optical character recognition algorithm which using bicubic interpolation method for the catalog retrieval when the input image has rotated text, blurred, various font and size. In this paper, applied optical character recognition algorithm consist of detection and recognition part. Detection part applied roberts and hausdorff distance algorithm for correct detection the catalog of book. Recognition part applied bicubic interpolation to interpolate data loss due to low quality, various font and size text. By the next time, applied rotation for the bicubic interpolation result image to slant proofreading. Experimental results show that proposal method can effectively improve recognition rate 6% and search-time 1.077s process result.

The purpose of this study is to analyze the status of e-books usage in small university library and to suggest implications for e-book management policies. To do that, a survey was conducted with students in a local small university, and the valid responses of 259 people were analyzed. As a result of the analysis, the preference of paper books (71%) was higher than that of e-books (12%). However, satisfaction with e-books (45.6%) was higher than that of paper books (27.9%) if they had experience using e-books. In addition, satisfaction was highest when using e-books for general reading, and it was found that the use device preferred to use a tablet. Based on the results of this study, we proposed some suggestions; 1) establishment of e-books service policy and promotion plan, 2) use of e-books dedicated devices and development of user-friendly e-books using environment, 3) providing various topics of e-books, 4) formation of an association for joint use of e-books between small library universities.

The causes which affects the deterioation of paper arc paper structure, papermaking process, temperature and rative humidity, light and biological agents. Paper made from cllulose fibers by the wood and the nonwood, This paper structure is further hydrolyzed by acidic additive such as the sizing agents during the manufacturing process. These additives leave residual acids in the paper, which break the cellulose clown to simper molecules. The results is weak paper and bas caused most of the damage to book. This study was carried out to investigate the presevation and the deacidification for the permanenece by the book. The deacidification and the chemical agents aims to nutralized the aicd in paper and add alkaline to it as a buffer to withstand future acid attacks. By applying the system to the acid paper with a pH of 4.5 neutralized a pH of 8.5. The expected of alkaline reserved paper extend about 2times and 3times than acidic paper.

This study investigated the various editions of Huangjenaegyeongsomun (黃帝內經素問) published in the Joseon Dynasty. Only study for on Eulhae metal type (乙亥字) Huangjenaegyeongsomun and bibliography research of some holding institutions are the existing research on this topic. The conclusion of this paper is as follows. 1. The 14 and 15-volume book are existing most common versions of Huangjenaegyeongsomun (黃帝內經素問) published in Joseon Dynasty. The two books were corrected by Naeuiwon (內醫院). According to this study, the latter is more early than the former. But in the study of the past were not made clear distinction between the two books. 2. The 15-volume book of Huangjenaegyeongsomun (黃帝內經素問) was published in the mid-18th century between the first half of the 19th century. 3. A Wooden print editions Huangjenaegyeongsomun (黃帝內經素問) about Japanese invasion of Korea in 1592 ago have been investigated holding institution. 4. The Gyeongju-published Huangjenaegyeongsomun (黃帝內經素問) is estimated that in the mid Joseon Dynasty, This edition has been estimated that the late Joseon Dynasty far.

The book ${\ll}$Ceyuan Haijing${\gg}$ studies inscribed and circumscribed circles in a right triangle and shows equations that give the diameters of the circles. We discuss the development of mathematical contents written by the scholar Yang Zhaoyun in Qing dynasty on the contents of ${\ll}$Ceyuan Haijing${\gg}$ in his book ${\ll}$Jiuyong Yandai${\gg}$. He derived equations to find the diameters of the circles based on algebraic knowledge known in the Qing dynasty. In this paper, we conclude that Yang's methods in devising the equations include the Gou-Gu Theorem, mathematical expressions derived from Gou-Gu ratio table, and the technique of interchanging triangles and events. We conclude that the Gou-Gu ratio table was a very important tool when Yang devised the equations in ${\ll}$Ceyuan Haijing${\gg}$.

Existing works to measure readers' understanding of interactive e-books have mainly employed quantitative approach which are difficult to get direct interpretation of the evaluation results. Attentive to interactive, visual and narrative features, this paper proposes a new method for measuring readers' engagement by making them to reconstitute a storyboard. Experimenting with real readers, we validated that this method could give a qualitative assessment that allows finding out problematic narrative phases and the adequacy of interaction formation.

The paper brings to question how image as a medium is becoming a replacement for traditional letters in the modern culture. Reflection the importance of image in the context of modern society with the changes in the values of communication. The importance of letters in its traditional format as a book that signified not only the method of communication but also power for those who governed during the days of illiteracy in the past has changed, in the beginning with the development of printing and today with movies etc. that supply endless images instead of words as a means of communication. The images are the next generation in the method of communication and can be noted from the earliest civilizations such as Egypt where the method of communication was not words but drawings that depicted specific significations. The use of images for communication purposes in light of this fact suggests that images was being used before words in societies and its communicative values greater than that of words.
