As Information & Communication Technology is developed in fast speed, the educational field undertakes many changes in utilizing Information Technology(IT). As the smart phone's educational utilization brings many positive effects, so many people are interested in such educational application programs. The e-textbooks or learning contents based on the web have shown some limits in being utilized as main learning materials in school field. So this study identified such limits, and suggested a new direction for professional education by integrating mobile and QR code technologies with existing textbooks to realize a new book-type E-Textbook model. And this study purposed for students to participate in their classes more easily through making open-education environment for students studying specialized subjects and by applying new teaching-learning methods inducing more interest in them. Of course, this study's ultimate purpose is to raise students' learning ability about specialized subjects, and further, to improve their self-directed learning abilities with increased interests in classes.

Increasingly advanced Information Technology (IT) has changed the operator so as to create more diversified and advanced traffic information demand. To deal with the changing demand in private sector, a concept of on-demand traffic information has been rapidly introduced. However VMS, a product of the first generation of ITS, which was designed to provide the unspecified individuals during driving the car with the basic level of traffic information by the public failed to actively change itself in such a changing pattern. This study was intended to describe the VMS system (tentatively, FM-VMS) which was further developed to accommodate the needs favoring the sophisticated PDA with the public role of providing the unspecified individuals with the equal information. FM-VMS introduced in this study is the device designed to transmit the voice and message to the drivers through the radio information device mounted on a car. A core technology is, unlike FM-DARC and RDS, the Water Making technology which directly inserts the digital signal into FM frequency in use. It's been currently used for broadcasting and security purpose. A detection rate as a result of testing FM-VMS system using Water Making technology was 90% or more in voice and message within 20m from test VMS. When a public-developed VMS information could be transmitted using FM frequency to the relatively vulnerable users (vulnerable to traffic information) in voice on a real-time basis to provide the regional traffic information, and furthermore, VMS message could be received through radio liquid using FM frequency only, it would obviously bring about the innovation in ITS as well as pave the way for creating the new added value down the road.

In this paper, we propose a procedure to multiple SNS channels automatic streaming through multiple output channels including the output channel of an external streaming server. The multiple SNS channels automatic streaming server includes an output management module for controlling the transmission of video contents to RELAY module that establish two or more output channels. In this paper, we experimented by separate with HD and FHD video using RELAY module in multiple SNS channel automatic streaming. In stream modules using RELAY module of HD video, when the publisher client and the player client and the RELAY module are 1 channel, the occupancy rate of CPU is 0.6% and the occupancy rate of heap memory is 0.3%(20 Mbyte). When the publisher client and the player client and the RELAY module are 183 channels, the occupancy rate of CPU is 99.9% and the occupancy rate of heap memory is 45.8%(3.7Gbyte). Therefore, the paper is not limited to the size of the streaming server by extending the output channel from which the video is transmitted to the output channel of the external streaming server. And a process of allocating an output channel of an external streaming server to an output channel through which an video is transmitted can be easily performed, so that an efficient output channel management can be performed even when a plurality of videos are transmitted.

This paper presents the architecture and its function of Tool server. MPEG-21 will enable all-electronic creation, delivery and trade of digital multimedia content and transparent usage of various content types on network device. Therefore, we can provide access to information and services from almost anywhere at anytime with various terminals and networks. In order to support multimedia delivery chain that contains content creation, production, delivery and consumption, we need some elements to identify, describe, manage and protect the contents. Thus, we define Digital Item Processing(DIP), Digital Item Adaptation(DIA) server and Tool server as primary objects of MPEG-21 multimedia framework. DIP provides a function which creates and consumes Digital Item(DI) as a kind of a digital object by user. DIA server adapts the original DI to the usage environment description sent from the terminal and transmits the adapted DI to the terminal. Tool sewer searches for a tool requested from DIP or DIA and downloads the best tool to DIP or DIA server. In this paper, we present how Tool server is organized and is used among 2 primary objects. The paper is structured as following: Section 1 briefly describes why MPEG-21 is needed and what MPEG-21 wants. We see the basic architecture of tool server and its functionality by each module in section 2. Section 3 explains a scenario that tool server transmits tool to DIP or DIA. The paper concludes in section 4.

Context-aware adaptive service for overcoming the limitations of wireless devices and maintaining adequate service levels in changing environments is becoming an important issue. However, most existing studies concentrate on an adaptation module on the client, proxy, or server. These existing studies thus suffer from the problem of having the workload concentrated on a single system when the number of users increases md, and as a result, increases the response time to a user's request. Therefore, in this paper the adaptation module is dispersed and arranged over the client, proxy, and server. The module monitors the contort of the system and creates a proposition as to the dispersed adaptation system in which the most adequate system for conducting operations. Through this method faster adaptation work will be made possible even when the numbers of users increase, and more stable system operation is made possible as the workload is divided. In order to evaluate the proposed system, a prototype is constructed and dispersed operations are tested using multimedia based learning content, simulating server overload and compared the response times and system stability with the existing server based adaptation method. The effectiveness of the system is confirmed through this results.

The purpose of this study is to analyze the characteristics that appear when actual comedy movie is made into animation, from the singularities which arise from producing remake of existing media contents into animation. Animation and slapstick comedy movies possess a similarity in that they both evoke laughter from the viewer via exaggerated motion, expression and action. In the case of live action film, people must carry out the acting and there exists spatial limitations, whereas animation does not have such limits, which allows the comic animation to materialize spatial scene directing and acting which are different from that of live action comic films, despite the fact that they share elements of the same genre. Accordingly, this study performs comparative analysis of and which is based on the contents of the same event, from the English comedy TV program and the , the TV animation which is a remake animated version of the original series, to conduct comparative analysis the character acting and the scene directing in accordance with the live action movie and animation. The result of studying the point that makes it easy to create comic genre into animation and the advantages possessed by the media of animation, through analyzing two works that deal with the same character and the same event, were as follows. It was proven through the analysis that comedic directing with doubled composure and amusement is possible through the anticipation of exaggerated directing in the acting through expression and action, and diversity of the episodes with added imagination in the story, as well as the estrangement effect of the slapstick expression and etc.

In this study, the problems In the current HDTV programming strategies were critically inquired into and reform measures were sought through in-depth interview with HDTV programming staff and program directors of the three major terrestrial broadcasting systems that are in their fourth year of HDTV broadcasting, and through analysis of the characteristics of HDTV programming. The analysis of this study showed that the time allocated to HDTV programs far exceeded the thirteen hours per week set by the Korean Broadcasting Commission. However, the percentage of HDTV programs broadcasted during the prime time was low, which as a result, limited the opportunity for the audiences to experience HDTV. furthermore, the low percentage of programs such as documentaries, sports, movies, etc. that are preferred by early adopters and through which the features of HDTV including high quality of picture, wide screen, etc. can be fully applied and shown did not appear to help in accelerating the popularization of HDTV In order to improve these problems, despite their having to bear the initial production costs, the broadcasting systems must come up with an aggressive strategies for the programming of documentaries, sports programs and dramas in order to strengthen the competitiveness in HDTV production and secure future adopters, and together with this, full support from the policy planning authorities and companies manufacturing electric home appliances, the other leaders in DTTB(Digital Terrestrial Television Broadcasting) transition, are necessary in order to promote the production of HD contents.

One of the major requisites for the success of the smart-TV is to create a circumstance where smart-TV app's are produced and purchased on a large scale. However, the smart TV app's may succeed only under the condition that the user interface of the smart TV is greatly evolved from the typical TV remote controller. Several equipments have been devised to tackle the problem of the poor user interface of the smart-TV; however, they are not satisfactory in the aspects that they usually increase the costs of TV-set and they do not help practically the app developers. The equipments are pre formed so that it is hard for the app developers to design their own user interface using them. In the paper, sMartUX, a method for developing the smart-TV app is introduced. sMartUX provides a new paradigm and development environment for designing, implementing, and operating the user interface of the smart TV app using a smart-phone. With sMartUX, app developers can design their own user interface using the various facilities of a smart-phone, and they need not to care the details of various smart-phones and how to launch their user interface onto a smart-phone.
