Mobile web standards-based the MUPS was built for global community and services of gsdc to spreading mobile devices rapidly. And for analyze Operational status and system resources of GSDC at n this paper researched and implemented system resource monitor method of gsdc to mobile web environment, in this paper researched and implemented system resource monitor method of gsdc to mobile web environment. Research support system of GSDC operated by scientific linux. Sysstat resource monitoring tools create a daily report through sar(system analysis report), after sadc(system activity data collector) collected system resource utilization information. In this paper, sar reports designed and implemented in mobile web to can visualize in a mobile environment. We do not depend specific OS by implementation of the mobile web. So we are available in variety mobile OS. And through provided visual graph, this system can monitor easily and more conveniently then the existing system.

A general medical information service in hospitals recently has been rapidly developed in the effective patient management due to the digitalization. In addition, the hospitals make an effort to support the medical information service in ubiquitous environment. A key requirement in ubiquitous environment is the ability to communicate between the image viewer system using the DICOM standard and a server system to support the medical information service. This paper describes a remote networking system based on the mobile terminal with RFID technology for the medical information service. In order to apply the overall configuration, we first implemented the DICOM viewer system, configured the database to store the patient information, and realized the server/client networking system in mobile terminal environment. In particular, this paper showed the capability for the medical image-based communication as well as the text-based communication.

In recent years, miniaturization has become the key factor in the development of mobile communication system. Portable communications and computing devices suffer from two conflicting requirements which are device size to be as small as possible and large, high resolution display. These problems can be solved by virtual display. Any display in which the user views an image through an optical system is a virtual display. It provides a display which is high resolution, appears large to the viewer and at the same time occupies little physical space. In this study, handhold units of mobile communication was investigated through use of the SLA(Scanned Linear Array). The basic SLA mechanism comprises a linear array of LED's, a magnifying lens, and a scan mirror. To optimize virtual image, we investigated optical system design and operating condition for each part.

In this paper, we developed digital TV interactive game using mobile device. This enables a TV viewer to participate in the game using mobile devices. Recently, advanced interface is adopted in the mobile devices, especially touchpad type interface is favorable. Such type interface has the advantage of more familiar interface for users, and the user can input various type of action. Using a mobile phone enables many users can participate in the TV game, and provides a private screen. In this paper, we describe contributions of the program in detail, and we present the architecture and a demonstration of the proposed program in a similar broadcasting environment.

Android that was made by Google and Open Handset Alliance is the open source software toolkit for mobile phone. In a few years, Android will be used by millions of Android mobile phones and other mobile devices, and become the main platform of application developers. In this paper, we develop an application contents Booky based on Google Android flatform by using Webview merits and Google search engine. The features of the developed content are as follows. First, a mobile-based Web browser which has an advanced screen resolution and can support more faster viewer than normal web browser as it reduces the amount of data transmission. Second, efficient E-book search and reading functionality. In the performance evaluation, we show the results of simulation using AVD(Android Virture Device).

This research is focused on an analysis on the structure of RAW image file and the development of a RAW image file viewer for an embedded device. Recently, several RAW image file formats are being used for saving and displaying the images created by various DSLR cameras, and the necessity of handing RAW images in mobile multimedia devices is increasing. For the development of RAW image decoding/encoding library applicable to WinCE-based embedded devices viewer, an analysis of RAW image file formats, such as CRW, CR2, PEF, NEF, MRW, have been performed because their formats are not released in public. By using the library, the analysis software which can extract RAW image data, 2~3 JPEG image files and other informations such as the specification of a camera and various photographic parameters from RAW image files, were developped and a RAW image file viewer which can run in WinCE-based embedded devices. The experimental result has shown that the viewer could encode and decode RAW image files successfully and it took approximately 10secs to load them to the screen in S3C6410 based embedded platform. The outcomes of this research cloud be a good information and solution to multimedia application developers.

As a new hybrid broadcasting service, augmented broadcasting shows enhanced broadcasting content on a large TV screen, while augmented reality (AR) on a mobile device augments additional graphical content onto an input image from the device's own camera to provide useful and convenient information for users. A one-sided broadcasting service using AR has already been attempted in virtual advertisements during sport broadcasts. However, because its augmentation is preprocessed before the video image is transmitted, the viewer at home may have no influence on this formation; and no interaction for the user is possible unless the viewer has a direct connection to the content provider. Augmented broadcasting technology enables viewers to watch mixed broadcasting content only when they want such service and to watch original broadcasting content when they do not. To realize an augmented broadcasting service, the most important issue is to resolve the hybrid content synchronization over heterogeneous broadcast and broadband networks. This paper proposes a novel hybrid content synchronization scheme for an augmented broadcasting service and presents its implementation and results in a terrestrial DTV environment.

The general medical information service in hospital recently has been turned into ubiquitous environment. A key requirement in ubiquitous environment is the ability for communication between image viewer realized by DICOM standard and a server supporting medical information to make it possible. In order to apply the proposed scheme, we first realized the server/client networking in mobile terminal environment. Second, we realized DICOM viewer using a PDA to be capable of wireless communication in ubiquitous environment. Third, MIPS(Medical Information Processing System) utilized RFID system to apply the patient's information efficiently. In particular, it showed the capability to communicate image based system unlike previous text based communication.
