"The Collection of Yi Chungmugong" manuscript is a hand-written manuscript of the volume 1 consisting of the Collection, published in 1795 and it seems to have completed the contents of the book by correcting the first part of the book before print. The book adopted a form of Seonjangbon(線裝本) of Ochimanjeongbeop(五針眼訂法) and was urgently needed some measures to preserve because it has been much damaged by stains, loss and oxidation due to moisture on the bottom of it. In addition, a scientific investigation was applied to find out the features of the quality of paper and fiber used for the book, which would be reflected in the process of the preservation. The characteristics of paper were measurmented for size(cm), thickness(mm), weight(g), basis weight($g/m^2$), density($g/cm^3$), chain line and laid lines($3{\times}3cm$). The measurement showed that the characteristics of paper used in royal books published in the late Joseon Dynasty. For the paper-fiber of the book, C stain was used and the technique revealed that the book is made of bast fibre of paper mulberry and its binding strings are cotton. SEM-EDS analysis was performed to verify the existence of additives in paper. As a result of the analysis, The crystallized calcium was detected in addition to the main components carbon(C) and oxygen(O). This artifact is the unique final version of "The collection of Yi Chungmugong", which has considerable value in terms of academic research, besides it helps to understand how to print books of Joseon Dynasty. And it also has a very accurate information of when and where the book was made, which primarily could be resources to conserve and restore for other book heritage.

An augmented book is an application that augments such multimedia elements as virtual 3D objects generated by computer graphics, movie clips, or sound clips to a real book using AR technologies. It is intended to bring additional education and entertainment effects to users. For augmented books, this paper proposes an adaptive keyframe-based page tracking method to estimate the camera's 6 DOF pose in real-time after recognizing a page and performing wide-baseline keypoint matching. For a page tracking, proposed method in this paper chooses a proper keyframe and performs a tracking in two step of coarse-to-fine stage. As a result, the proposed method in this paper guarantees a robust tracking to view-point and illumination variations and real-time.

The purpose of this paper is to report a newly discovered book whose title is Ikkam (翼鑑) and prepare for a full-scale study. The book, Ikkam, has a variety of contexts in which it seems to be written by Park Ji-won. First, 'Sanin' in 'Yeonam-Sanin' is consistent with the behaviors of Yeonam Park Ji-won who lived in hiding in the Yeonam valley in 1777. In addition, many statements written in the introduction, such as "as we stick to the old things, we do not know a makeshift", "we are well versed in changes" and "many soldiers are not always good" remind us of other writings of Park Ji-won. Moreover, he writes the statements using antithesis. It is the force of writing style of a literary person who is not engaged in medical service. In addition, he puts six qi in the introduction, but it is not as sophisticated as Jejungsinpyeon (濟衆新編). It suggests that this book may be published earlier than Jejungsinpyeon. When comparing Ikkam with Euimunbogam (醫門寶鑑) and Jejungsinpyeon, it seems common to place six qi in the introduction at the time. In addition, through this book, we find that Park Ji-won known as a writer of Geumryosocho (金蓼小抄) has fairly much knowledge in the medicine. We can estimate his passion and depth about the medicine through a longing for a new medical book shown in the introduction of Geumryosocho. However, various approaches to similar disease symptoms shown in the introduction help us to recognize his true qualities in the medicine. In addition, like other experience prescriptions, this book excludes prescriptions using medicinal herbs with toxicity or rare medicinal herbs in the situation with a limited supply of them in remote areas but includes prescriptions which are widely used. It shows that experience prescriptions in the Joseon Dynasty are effective to specifically identify medicinal herbs and prescriptions which are widely used in Korea. These values cannot be compensated by Donguibogam (東醫寶鑑) which has an infinite value.

Recently, consumer who has a desire to spend less money want to buy a cheap and good product because of long economy recession. Secondhand trading is regarded as a good method which allows people to buy cheap and good product. Activation of secondhand trading reduces the psychological distance among customers. Especially, in the case of expensive books such as major books, each university has community only for used book trading. However, existing used book community is hard to find current real-time trading state at a look, and it is impossible to purchase reasonably because of a one-way pricing of the seller. In this paper, we design and implement a used book trading web service using an auction system which can help anyone to trade used book easily. It is designed web based system and it provides convenience to user through efficient book registration function and book search function.

To improve the conventional illustrated fish book, this paper introduces the concept of an electronic illustrated fish book which applies IT techniques to the conventional one, and proposes the image retrieval for it. The image retrieval is a core technology of the electronic illustrated fish book and make it overwhelm the conventional one. Since fishes, even if the same kind, have different features in shape, color, and texture and the same fish can even have different features by its pose or environment at that time for taking a picture, the conventional image retrieval, that uses simple features in shape, color, and texture, is not suitable for the electronic illustrated fish book. The proposed image retrieval adopts detail shape features extracted from head, body, and tail of a fish and different weights are given to the features depending on their invariability. The simulation results show that the proposed algorithm is far superior to the conventional algorithm.

The terminals of e-Book(electronic Book) are classified into two types which consist of special-purpose terminal equipment and general-purpose terminal equipment. Although the terminal products inr the two types have had a strong race in the e-Book market each other, both enterprises and consumers want the two type to remain persistently with competition in good faith. Therefore, it is necessary for each type camps to find blue ocean by establishing differentiation strategies of each type. In this paper, we designed the research model that independent variables consist of hardware quality and software quality, dependent variable is user satisfaction, moderator variable is the terminal type. Through the research model, we investigated factors having a influence on the user satisfaction of the e-Book terminal that consists of hardware and software. In particular, we investigated if the degree of the influence is different between the two types. As a result, we got conclusions as followings. First, the quality of hardware and software in the terminal had significant influences on the user satisfaction. Second, the degree which the hardware quality has influenced user satisfaction was not different between the two types, but the degree which the software quality has influence on user satisfaction was different between the two types. As a implication of this result, we found that special-purpose terminal provider need to establish a strategies for raising the quality of e-Book viewer to provide different product from general-purpose terminal.

This paper describes the implementation of document image restoration system for the geometric distortion using structured light. To get accurate document images, the bounded book must be flattened by pushing down the book with a class plate. However, most of ancient documents are too fragile to be pushed. The proposed system restores the distorted character image due to geometric distortion.

The painter Leon Battista Alberti insisted that mathematics was very important in painting in his famous book "Della Pittura(On Painting)" at 15th century. At the first part of the book, he explained about points, lines, and planes mathematically. And he emphasized that the proportion was very useful for accurate description of objects. This is the perspective that Alberti showed by using visual pyramid. In this paper, we investigate the Alberti' s method and the background of Alberti's perspective.
