Digital leader caught seat by modern's everyday life tool now by popularization of smart device such as Smart phone and Tablet PC. Therefore, desire of readers about electronic book practical use is increasing based on convenience and economic performance of electronic book. 1971, Michael S. Hart established Project Gutenberg to produced first electronic book because inputs American Independence Declaration Statement by computer and produce more electronic books. After that, an electronic book technology repeats several times development and American electronic book take is increasing rapidly. Sales volume of electronic books is dramatically increasing in Korea since digital device such as Smart phone and Tablet PC became popular. This research attempts to analyze factors influencing on shifting from paper book to electronic book. Results of this research proposed grounds for building business strategy. Finding is the factor of social influence is only significant to acceptability intention. It means user of e-Book enhance their acceptability intention along social phenomena.

Introduction of digital broadcasting service does not only mean the change of information transmission method but also the change of total broadcasting system. In past day, Television was only received one-sided information from broadcasting station, but digital broadcasting means that digital television becomes the most important means of information transmission by the introduction of new programming, lots of channels, data service, multi communication. In the age of the digital broadcasting, the recording and replay medium's interest is getting higher. The medium is able to record more than 24 hours' digital broadcasting programs without additional tapes. In this paper the recording and replay device using HDD was implemented and device driver based on linux was programmed. It has Intel PXA250 processor and hard disk is used as storage equipment. And transport Stream is saved on hard disk through PXA250's data bus. FIFO is added to solve the different saving speed and FPGA is also added to display the saved data.

In this paper, a new method for controlling the pointing device on digital display using EOG(electrooculogram) which is generated from eye movement, was suggested. The manufactured system is consisting of pre-amplifier, A/D converter, serial transmission device and PC program. The EOG is amplified by pre-amplifier. And the amplified EOG is digitized and transmitted to personal computer via rs-232c by PIC16C74A. Finally, the software for controlling the pointer on digital display is developed on computer. As the result, the error between the real subject's viewing point and the point indicated by the developed pointing device on digital display was investigated into the average value, 0.72 degree for horizontal axis, 0.96 degree for vertical axis. The pointing device developed in this study is controlled by subject's eye movement, that is, the user's intention. Furthermore, the algorithm of this study is applicable for many field such as a new method remote control, a new wheelchair control and so forth.

IoT devices frequently require input resources to communicate with various sensors or IoT platforms. IoT device wastes a lot of time as idle time or waiting time to check the data of the input resource and use the input resource. In addition, IoT devices use various input resources. We compares and analyzes input idle time and input waiting time generated from hardware serial input resource, software serial input resource, digital port input resource, and analog port input resource using Arduino widely used as IoT device. In order to design the IoT device framework, it is necessary to understand the characteristics of input resources and to design them to minimize unnecessary input idle time and input waiting time. The analog input wait time has a much larger input wait time than the digital input wait time, so it must be designed to receive analog information periodically at the appropriate timing. The characteristics of the input resources analyzed in this way help to design an efficient IoT device.

The purpose of this study is to analyze the factors of action and reaction through the examples of luminescence digital fashion design, which is a part of the interactive digital paradigm in 21st century, and to classify types of interaction expressed in luminescence digital fashion design. The significance of this study is to provide an effective database for researches on new ideas and expression methods of fashion design using luminescence digital device. The contents are as follows. First, identifying the concepts of interaction, digital fashion, and luminescence digital device. Second, analyzing the factors that put the luminescence digital device into effect through materials such as the collected photos and the stimulus behind the materials. Third, analyzing and classifying types of reaction according to the types of stimulus in luminescence digital fashion design. Detailed use of luminescence digital devices in Fashion designs did not start until after 2000 so the scope of this study starts from 2000 and on. The methods of this study are as follows. The theoretical frameworks of digital fashion and interaction were setup by using information from various related books, papers, and internet sites. In addition, the empirical analysis was performed using collected photos and explanations through related Internet sites of digital fashion. Through the study, the interaction types in 21st century's luminescence digital fashion design can be expressed variously according to the current input type, biometric recognition type, environment recognition type.

Recently, with the enlargement of cloud computing, virtual desktop infrastructure(VDI) can be an alternative of the existing personal computer based information environment. For the case of partially introduced VDI coexisting with personal computer environment, we suggest a virtual folder based approach to control the overall digital contents within an organization with a case of implementation. Although a centralizing device was used for storage and sharing of organization's digital contents, it was not easy to accomplish centralizing digital contents completely. It is tried to prevent users from utilizing their own storage in their personal computers or virtual machines and to use virtual folder which transfer and store digital contents to and in EDMS. The virtual folder system of this paper looks like a real folder in a personal computer, but it is another virtual device for outer storage devices including EDMS. It can be an alternative and reference of digital contents control for future applications of cloud computing.

Recently, as the prepress mainstream is changed to the digital wolkflow, various digital proofing systems such as high price dye sublimation printers and low price ink jet printers are widely used in printing industry. Generally, CRT monitors are also often used as a soft proofing device for hard-copy image output. However, displayed color image on CRT monitor does not match to the actual color printing sheets. Because, the color space of CRT monitor used RGB color space, and it is differ with printing device color space, CMY. Therefore, proper color compensations are needed to match the colors between hard-copy proofs on the printing device and soft copy proofs on the monitor. For the proper compensation, we used LUT and gamut mapping method for color space transformation between device dependent color space and device independent color space, vis a vis. This paper shows the application method and the usefulness of CRT monitor for the soft-copy proofing using the output characteristics of printing device.
