A Digilog Book is an augmented reality (AR) based next generation publication supporting both sentimental analog emotions and digitized multi-sensory feedbacks by combining a conventional printed book and digital contents. As a Digilog Book authoring software, ARtalet provides an intuitive authoring environment through 3D user interface in AR environment. In this paper, we suggest ARtalet authoring environment based trajectory editing method to generate and manipulate a movement path of an augmented 3D object on the Digilog Book. Specifically, the translation points of the 3D manipulation prop is examined to determine that the point is a proper control point of a trajectory. Then the interpolation using splines is conducted to reconstruct the trajectory with smoothed form. The dynamic score based selection method is also exploited to effectively select small and dense control points of the trajectory. In an experimental evaluation our method took the same time and generated a similar amount of errors as the usual approach, but reduced the number of control points needed by over 90%. The reduced number of control points can properly reconstruct a movement path and drastically decrease the number of control point selections required for movement path modification. For control manipulation, the task completion time was reduced and there was less hand movement needed than with conventional method. Our method can be applicable to drawing or curve editing method in immersive In-Situ AR based education, game, design, animation, simulation application domains.

ePUB is one of the most pervasive eBook formats since it was announced as a 2009 standard in IDPF(International Digital Publishing Forum). ePUB is compressed as a ZIP Archive format and structured as a standard format of OCF. Domestically and internationally, eBook services applying DRM into ePUB have currently been active, while it does not satisfy various needs from business because it does not support preview service which is due to the encryption of the whole ePUB as a single key. This study suggests a way to apply diverse business models by providing eBook content based on ePUB multiple key encryption method, not by encrypting it simply as a single key. The encryption method which applies a multiple key encryption method is suggested as a practically appliable form together with licence issuing and delivery method and decryption method in eBook readers. The multiple key encryption method suggested in this study will make it possible to support partial preview services of ePUB based eBook content. It will be applied to diverse service models and enhance the security level better then single key based encryption method.

In this paper, we describe about interactive electronic book utilizing tabletop display interface and digi-pet. Because of this system can define a lot of gestures using touch point of finger, help that user experiences electronic book effectively more than existent input device. Also, support 1 users in 1 input device in existent mode, but this system can expect various effect because support Multi-user. The digi-pet(digital pet) is physical tools that convey emotion between tabletop display platform and user. And this shows various results acting as assistance because becomes master of story of imagination and participate directly on talk and makes change of story. In this paper, we described about oriented electronic book system the future that combines tabletop display and Digi-pet. This system is expected that the usefulness is increased by leaps and bounds along with technology development forward.

Recently various electronic books (I-Book) based on PDA (personal digital assistance) that we can easily use anytime and anywhere have been developed. Volume and weight of the E-Book is much less than that of traditional books. In that reason, it is easy to carry and serve us with contents by diverse functions such as searching, bookmark, dictionary, and playing of color image, sound or moving picture. On account of these advantages, many products connected with I-Book have been emerged in the market. However a product connected with educational contents is scarce, because it requires not only normal function but also additional functions such as a problem solving. Therefore it is actually necessary to develop a browser and an editor for educational contents. In this paper, we express educational contents by XML and define structure of document with XML schema. Then, we design and implement an editor and a browser that can manage educational contents on PDA.

The purpose of this study is to identify the problems of the e-book composition provided by the Comprehensive Reading Education Support System and to propose a service improvement plan related to the establishment of e-books in school libraries as educational resources based on practical issues and perceptions experienced by teacher-librarians. As a research method, the composition of the collection of 3,002 e-books supported by the Busan Comprehensive Reading Education Support System as a reading education platform of the school library was analyzed based on the Korean Decimal Classification. Based on this, two focus group interviews (FGI) were conducted with 4 elementary teacher-librarians and 5 secondary teacher-librarians working in Busan. The result of this study can be used as basic data to support students' reading activities using e-books as educational resources and to form an efficient e-book collection in school library.

E-book markets are currently moving through a period of disequilibrium as new pricing structures (i.e., flat-fee subscriptions) are rapidly embraced by major vendors. On the basis of a novel dataset, we investigate how the availability of "all-you-can-read" pricing programs influences consumers' tariff choice and contract renewal behaviors. Consistent with the rational choice framework, the findings suggest that most e-book consumers significantly gain from subscription-based tariffs. Power readers prefer flat-fee subscriptions, and those that have economically benefited renew their subscription. However, we also find some other intriguing results. Among the three subscription designs examined, the 1-week plan affords consumers more economic benefits than do 1-day or 1-month programs. Finally, iOS users are more inclined to select subscription models than are Android users because of the absence of in-app purchase functionalities for the former. The unavailability of in-app purchase affects tariff choices and transaction patterns as it increases transaction costs.

In this paper, we had tried to study advertising method of local industry in cooperation with SNS (Social Network Service). In particular, This paper analyzes the Facebook Page trying to find a way to take advantage of the local advertising. To analyse the Facebook page, I had created three Facebook pages such as at Hongik UNIV., Gangwon National UNIV., and specialities in Cuncheon cities. While I was managing the three pages, I had analyzed the results of quantities of activities, and in addition, had used NodeXL for the analysis of the network for the each page. After the analysis of the data of each page, I had found the possibility of the promotion for the successful the local advertizement associated with SNS. To verify and develop the results of my study, I had designed the " real time local advertising APP which is connected with SNS like Facebook, had created server program based on PHP, Android APP. In the future, I have found that there must be a lot of possibilities for the successful and various the local advertising methodologies by using SNS like Facebook, the operational data of the App.

Despite recent changes in life style, the content called bookstore has steadily stood by our side, changing its shape. In this environment, This manuscript is a quantitatively empirical study that individual innovation affects a combined bookstore's service design factors and the user's intention to word of mouth. Researchers believed that individual innovation would affect a combined bookstore's service design factors. It was also assumed that there would be considerable causality between the combined bookstore's service design factors deduced through prior study. Furthermore, the assumption that these parameters would affect internal variables, perceived ease of use, perceived usefulness and satisfaction, word of mouth intentions was presented, and verified using An Integrated Model of Extended Technology Acceptance Model and Post Acceptance Model. Researchers expect that this research will contribute significantly in that it is a developer's approach to the combined bookstore that are seen as major tenants in large retail facilities.

Paradoxically, in the age of video like Youtube, audio books are rapidly growing. Audio books are the result of complex influences such as digital detox trends that try to distance themselves from digital devices in the age of smart devices. The biggest advantage of audio books is that they can read books with "mutitasking" while working or driving, unlike video or text. The audio book market has already become the fastest growing industry in the publishing sector in recent years abroad. Various platforms specializing in audio books are also appearing in South Korea and China. We hope that applying these audio books to Chinese literature education will have many effects. In particular, the addition of Chinese sounds to the Chinese-Korean translation text can dramatically enhance students' accessibility. Also, if the Chinese phonetic synthesis technology is applied to web pages and the text and sound of Chinese literature works are served at the same time, the effect will be maximized. In particular, intelligent voice synthesis during the Fourth Industrial Revolution will be an alternative to overcoming the limitations of mechanical speech synthesis by developing a voice engine using the natural sound of the reader.
