Ubiquitous Computing is an agriculture revolution, the Industrial Revolution, the fourth revolution to equal an information revolution are Ubiquitous Computing. Historic agriculture was revolutionary, but the Industrial Revolution was a revolution of the physics space that was a base of a mankind civilization, and the information revolution that Cyber Space saw a prime while world wide web service was expanded was a revolution of cyber space. Be charmed with this, and, as for the Ubiquitous Computing revolution, it is achieved a physics space and an intelligent union of cyber space in the space where an off-line space was integrated with compunction on-line. It is combined with a life space naturally, and Ubiquitous creates a new integrated space. The space is the opportunity space that is limitless as soon as it is the unknown world that mankind was not able to experience yet. This paper checks the present situation of currently proceeding Ubiquitous computing technology(RFID, CCTV) in augmented reality environment. Also, The main purpose of this paper is to analyze the concepts analysis of privacy, personal information, and electronic surveillance in augmented reality environment. Thus this paper treated the analysis of case, technological issue, problem and solution and so on.
A Study on Present State and Perspective of E-Book Contents Industry
Kim, Kyung-Il ;
Journal of Digital Contents Society, volume 7, issue 2, 2006, Pages 83~88
This article inspect e-book contents industry that is a fairly new arrival contents industry field in the last decade of the last century. Basing the theoretical background and survey research, made a diagnosis of the future of e-book contents industry. The result of this article is that e-book contents industry will grow a important content industry.
Study on the Effective System for P2P
Song, Eun-Ji ;
Journal of Digital Contents Society, volume 7, issue 2, 2006, Pages 89~94
It can be said that P2P means the pattern that every linker could be both a supplier and a customer by means of the direct connection and survey with personal computers out of the concept of server and client. P2P business has been a great impact all over the world. for it came to be possible as the express internet log-on service is getting widely used and the user environment is getting better with the supply of high-tech computer. Recently the various system of P2P has been developed not as the only service of file share between the personal users but as the application of the electronic trade between the companies. This study is to suggest the most effective system that has the function of complement of P2P.
A empirical study on the design of project-oriented teaching models to bring up the experts in the multimedia industry

Journal of Digital Contents Society, volume 7, issue 2, 2006, Pages 95~102
To meet the high demand of the experts in the multimedia industry, many colleges opened the subject related to multimedia technology and pre-learning has been rapidly increasing among the students. However, most instructor is still appling the traditional teaching model rather than the one customized for the pre-learner of multimedia. This paper is to reveal the pre-learner's strong desire in detail and suggest the characteristics of the teaching model and teaching materials. We applied the new paradigm, constructivism and problem-based learning, which rising in the educational literature to suggest and design the lecture model to bring up the experts in the multimedia industry.
Performance Evaluation of Low Rate Wireless Home Network Embedded DSSS System
Roh, Jae-Sung ;
Journal of Digital Contents Society, volume 7, issue 2, 2006, Pages 103~108
Short-range wireless communication and networking technologies are becoming increasingly important in enabling useful mobile applications. for example, ZigBee technology is expected to provide low cost and low power connectivity for equipment that needs battery life as long as several months to several years. In addition, ZigBee can be implemented in mesh networks larger than is possible with Bluetooth. The main features of this ZigBee standard are network flexibility, low cost, very low power consumption, and low data rate in an adhoc self-organizing network among fixed, portable and moving devices. Home network/Home automation is one of the key market areas for Zigbee, with an example of a simple network This paper investigates the effect of short range wireless channel on the performance of Zigbee system and DSSS-BPSK signal transmission in AWGN, interference and Rician fading environments. And we investigate performance degradation due to interference and fading effects in short range wireless channel. In particular, the impacts of the fading and interference level on the bit error probability is shown in BER performance figures.
Design and Performance Evaluation of Equalizer for the S-DMT Cable Modem
Cho, Byung-Hak ;
Journal of Digital Contents Society, volume 7, issue 2, 2006, Pages 109~115
In this paper, we design and performance evaluate the equalizer for S-DMT table modem, which supports more channels and better quality symmetric mutimedia services over HFC network. We verified that both of the designed equalizers show good convergence characteristics and that the performance of the time domain equalizer is 1 dB better than that of the frequency domain equalizer overall range of Eb/No.
Implementation of Multimedia Contents Stream Service Mobility by Location Tracking
Kim, Ji-Young ; Yong, Hwan-Seung ;
Journal of Digital Contents Society, volume 7, issue 2, 2006, Pages 117~124
In ubiquitous computing environment, a user can access their personalized services at anytime, anywhere, through any possible mobile or fixed terminals in a secure way. If the user wants to move to a different location, they need to stop the video play at the current location and makes a new request at the new location. As well, the user needs to manually search for the last frame to be seen at the previous location. In this paper, we proposed an implementation of multimedia contents streaming service mobility by user's location tracking. User can play video seamlessly while moving from one machine to another along the user's moving trail.
The KEM OWL Binding
Chang, Byung-Chul ; Cha, Jae-Hyuk ; Ham, Dall-Ho ;
Journal of Digital Contents Society, volume 7, issue 2, 2006, Pages 125~131
In the recent year, the need for effective searching for e-learning contents has emerged as a revitalization of e-learning. Therefore, there are many studies for the contents searching method that make use of semantic web technology. Also, there are many studies to apply the ontology as the core technology of sematic web to e-learning. In this study, we bind the KEM(Korea Education Metadata) that enacted as the first technical standard of e-learning, KS X7001, in Dec. 2004 with OWL to use the metadata for a effective searching with ontology through the solving of the problem of metadata. And, we discuss some problems that occur in progress of binding and the solutions.
