As the propagation of smart devices has increased and the variety of the devices also has been diversified, various existing functions are concentrated on these smart devices. One of the phenomena is that the paper-book market has partially transferred into an e-Book market. As the demand of the e-Book has increased over time, the improvement of the types of e-Book on the market can be observed. In this study, the usability evaluation on the interface of the e-Book viewer for the types of application, which can be installed in the smart devices, has been conducted. The items for the usability evaluation of the e-Book were defined, the usage patterns were observed objectively and a questionnaire technique was applied. By analyzing the usability evaluation of e-Book interface, the directions for production and improvement of e-Books have been suggested.

The transmission capacity has been highlighted as a problem in the power company according to operated heavy loaded of transmission facility. The total transfer capability in the KEPCO power system is determined mainly by the voltage stability limit and many approaches for enhancement of the total transfer capability has been consistently performed. This paper proposes a study on determination of the adequate var sizing of power compensator regarding the transfer capability enhancement in power system. This method was controlled power compensator in substation becasue of the voltage stability. It was simulated power system using EMS peak data.

In recent times, the high-tech society has become the most important issue by IT technology and publication network. Today such flows have also been the case in the e-book field. Today's electronic publication is changing day by day. But there are some problems according to the prevalence of e-book. E-book is similar to p-book(paper-book). There is a limit to have perfect feeling of a texture of p-book. In order to purchase an e-book, people use online. People having malicious intent could copy and distribute it illegally. It leads to cyber abuses. This paper aims at the copyright protection of e-book ePub writers. The proposed e-book copyright protection system is designed using e-book production Sigil environment and C program environment. This system uses client-server communication through e-book ePub as authentication information. It discerns whether to permit or not for a client to read the e-book using authentication information. Authentication information includes ID, password, IP address, limited time of authentication information, GUID(Globally Unique Identifier). If authentication information about e-book meets requirements, people can use it. But if not, it blocks people's approach by quitting program.

The sample book was printed in 1935. Since the books in the early twentieth century were printed using acidic paper, the color of the paper would change to brown over time due to iron corrosion. In addition to corroding iron cores, the acidity of the paper (pH 3.2) also made the paper brown and fragile, as was true in the case of the sample book. To clean the paper of the sample book and to make it strong, we replaced the iron core and performed wet cleaning on the paper to remove contaminants. Then we pressed the sample book dry, and subsequently linening every page with Minoshi($4g/m^2$). Generally, book conservator rebinding the book using wires or threads: however we have devised a new method to rebind the book using colored iron cores. To color the iron core brown, they were dipped in an aqueous coloring solution ($H_2O$, $C_2H_5OH$, $CuSO_4{\cdot}5H_2O$, $FeCl_3{\cdot}6H_2O$); subsequently, a 20% paraloid B-72 was applied to protect the colored iron cores from corrosion.

The information about eBook cannot be added automatically to library catalog because the eBook Service Provider does not provide enough eBook metadata. Therefore, this paper was developed the eBook library's metadata in order to maintain the compatibility and interoperability analyzed the eBook service provider's metadata, KS X 6100 metadata, Dublin Core, MARC, and TEI Header, and extracted common meradata elements from them. We defined these common metadata elements as a core element and added other elements that uniquely describe eBook characteristics as a detailed adn additional elements for eBook metadata.

In this paper, we propose a mobile book management application using the camera of a smart phone and the open API book information provided online. The camera automatically scans the bar-code or QR-code of a particular book. The code of that book is used to transmit detailed information to the open API. Then the proposed application records this information for use in an "Scan list" or an "My book list". This application notes the page of the book that the user is currently reading and, if the user has read the entire book, he or she can comment about it. Therefore, the proposed application provides useful functions so that the users can manage their books effectively.

The emergence of E-book have allowed readers to interact with other readers and to actively participate (e.g. social reading). Furthermore, there is a growing demand in writer's community to take the advantage of the feedback from their readers to update the content of E-book. To do that, they require the service that utilizes the user feedback while creating or updating the e-book content. This study aims to let authors collect and to apply the reader's feedback on E-book content. However, in order to apply the user feedback, users first need to explicitly type the feedback, and even if they do, authors need to develop the software to automatically analyze and to apply the user feedback. This makes difficult for authors without programming background to produce E-book with automatic content adaptation. In this paper, we propose Feedback Clue Model to generate, analyze and apply the user feedback into E-book content. Based on this model, we develop the block editor which allows easy implementation of E-book that can be dynamically updated.

DRM(Digital Rights Management) is essential for the copy right protection of eBooks based on ePub 3.0 by IDPF. In this paper, we developed eBSS(eBook Service System) as ePub 3.0 builder and viewer system with DRM and proposed an efficient DRM method which improves the performance of contents generation, security and distribution system. The efficient application of DRM method to the eBook contents based on ePub 3.0 for smart phone is practically useful for eBook service system. It is very useful for the suggested eBSS with DRM method and strategy to apply easily and practically to the encryption and decryption of the eBook contents. Also, it is very efficient to generate the ePub 3.0 contents and to apply DRM method to it especially, by using practically this suggested ePub 3.0 builder system from the view point of the eBook content generation and its viewer such as eBook reader for user and eBook providers.

In this paper, we apply the learning of the mobile robot insect augmented reality Digilog Book. In the era of electronic, book written in paper space just have moved to virtual reality space. The virtual reality, constraints spatial and physical, in the real world, it is a technique that enables to experience indirectly situation not experienced directly as user immersive experience type interface. Applied to the learning robot Digilog Book that allows the fusion of paper analog and digital content, using the augmented reality technology, to experience various interactions. Apply critical elements moving, three-dimensional images and animation to enrich the learning, for easier block assembly, designed to grasp more easily rank order between the blocks. Anywhere at any time, is capable of learning of the robot in Digilog Book to be executed by the mobile phone in particular.
