As communication technology, an enabling technology for ITS, becomes diversified with DSRC, CDMA, Wireless LAN, it is expected that type and function of ITS services will become gradually expanded. As a result, research and development of a standard platform that can provide support so that numerous communication technologies that are being used in various ITS services to receive various ITS services can be operated in one integrated terminal are being carried out. On Board Unit (OBU) for a recent standard platform was also built and tested recently. However, verification for standard suitability of the standard platform OBU that was developed must be carried out. Standard technology must be realized and sufficient functional and operational testing must be carried out in order to guarantee efficient operation in an actual ITS system and increase utilization of standard technology. Therefore, In this paper we had constructed test road and we had tested a standard platform OBU for a standard application.

The competition among companies in converged market of broadcasting and telecommunications has become severe. Companies in this market have vertically integrated critical resources by acquiring or strategically allying with relevant companies. However, the expansion of business territory accompanies financial, organizational, and technological risks. As such, it is important to identify critical success factors that highly affect the company's competency. This study is aimed at delivering strategic implications for firms playing in the converged market of broadcasting and telecommunications by drawing the priorities of competitive resources to acquire. To do this, we selected four teen specific core resources on CPNT (content- platform - network - terminal) value chain. Then, we conducted an Analytic Hierarchical Process (AHP) using data from experts in this industry. As a result, the priority for acquisition of competitive resources is presented as follows: broadcasting programs, implementation of TV application store, multi-platform, investment on wireless network, and diffusion of mobile devices. In addition, the result shows that the platform-centric vertical integration is the most promising strategy for competition.

In this paper we propose the structure of MPEG-4 multimedia player platform for Terrestrial Digital Multimedia Broadcasting (DMB) Service. Korea will launch DMB service at next 2004 you based on Eureka-147 Digital Audio Broadcasting (DAB) Service System. This new mobile multimedia broadcasting services provide not only high quality digital audio broadcasting services, but also various multimedia data broadcasting services including high quality video. For the sake of MPEG-4 Systems technologies, it will provide an interactive service to users in the near future. Therefore it terminal shall have various functionalities as well as playing audio-visual contents. However there is no precedence standard for such mobile interactive multimedia broadcasting system. Therefore it is very import to provide the multimedia player platform of DMB service for accelerating the development process of commercial terminal and providing a direction of next DMB terminal structure.

In this paper, we design and implement the architecture of the ubiquitous software robot platform (Sobot platform) based on Web 2.0. In order to provide a user with the personalized emotional service by transferring to any device without any time or geographical limitations, the software robot must be developed as a form of a platform based on the standardized data and structures. To verify the effectiveness and the feasibility of the proposed Sobot platform consisting of the terminal platform, the server platform, and the contents composer, we compose user-created emotional Sobot contents messages on heterogeneous platforms such as PC, a mobile phone, a PDA, and a web portal site and experiment a variety of Sobot transfer implementation between them.

텔레매틱스는 차량의 위치측위기술과 양방향 통신이 가능한 시스템을 이용하여 차량내 정보단말을 통해 차량과 운전자에게 다양한 정보 및 서비스를 제공하기 위한 종합적인 시스템을 의미한다. 다양한 서비스에 대한 요구가 점차 증가함에 따라, 다양한 첨단 기술들이 단말에 도입되고 있으며, 텔레매틱스 단말은 서버로부터 다양한 통신 수단을 통해 가동되어 전달되는 각종 서비스 정보 및 응용 소프트웨어를 사용자에게 제공하기 위한 실행 환경을 제공해야 한다. 이에, 본 논문에서는 AMI-C 기반의 텔레매틱스 단말용 응용 미들웨어를 제안하여, 공통적으로 단말이 제공해야 하는 서비스들을 제공하여 단말용 서비스 구축에 드는 시간과 비용을 줄이고자 한다.

Recently, the number of attacks by malicious application has significantly increased, targeting Android-platform mobile terminal such as Samsung Galaxy Note and Galaxy Tab 10.1. The malicious application can be distributed to currently used mobile devices through open market masquerading as an normal application. An attacker inserts malicious code into an application, which might threaten privacy by rooting attack. Once the rooting attack is successful, malicious code can collect and steal private data stored in mobile terminal, for example, SMS messages, contacts list, and public key certificate for banking. To protect the private information from the malicious attack, malicious code detection, rooting attack detection and countermeasure method are required. To meet this end, this paper investigates rooting attack mechanism for Android-platform mobile terminal. Based on that, this paper proposes countermeasure system that enables to extract and collect events related to attacks occurring from mobile terminal, which contributes to active protection from malicious attacks.
