Since Korean mobile communication companies each use different mobile platforms, developers must configure and translate their game contents to run under each of the platforms so that they can be serviced correctly. Nevertheless, such translation tasks require lengthy times and costs. This is one of the reasons why a variety of contents could not be provided. In order to mitigate such difficulty, this paper implemented an automatic mobile contents translating system that automatically translates mobile C game contents of the GNEX platform to mobile java contents of the WIPI platform. The GNEX C-to-WIPI Java automatic contents translation system helps minimize the amount of time and cost required in servicing contents to different mobile communication companies by promptly translating a platform-specific-content to run under other platforms. Also, the automatic translation and servicing of existing contents increases the reusability of these contents and also the productivity of new contents thereby offering users with a more variety of games.

Since korean mobile communication companies each use different mobile platforms, developers must configure and translate their game contents to run under each of the smart phone platforms so that they can be serviced correctly. Nevertheless, such translation tasks require lengthy times and costs. This is one of the reasons why a variety of contents could not be provided. In order to mitigate such difficulty, this paper implemented the mobile contents converter system that converts mobile game contents of the GNEX platform to smart phone contents of the iPhone platform(iOS). The GNEX-to-iPhone automatic mobile contents translation system helps minimize the amount of time and cost required in servicing contents to different mobile communication companies by promptly translating platform-specific-contents to run under iPhone smart phone platforms. Also, the automatic translation and servicing of existing contents increases the reusability of these contents and also the productivity of new contents thereby offering users with a more variety of games.

Nevertheless, such translation tasks require lengthy times and costs. This is one of the reasons why a variety of contents could not be provided. In order to mitigate such difficulty, this paper implemented an automatic mobile contents translating system that automatically translates mobile C game contents of the GNEX platform to mobile java contents of the Android platform as a smart platform using a source-level contents translator. The GNEX C-to-Android Java automatic contents translation system helps minimize the amount of time and cost required in servicing contents to different mobile communication companies by promptly translating a platform-specific-content to run under other platforms. Also, the automatic translation and servicing of existing contents increases the reusability of these contents and also the productivity of new contents thereby offering users with a more variety of games.

Nevertheless, such translation tasks require lengthy times and costs. This is one of the reasons why a variety of contents could not be provided. In order to mitigate such difficulty, this paper implemented the contents analyzer and the resource converter of the automatic mobile contents converter system that converts game contents of the mobile platform such as the WIPI and the GNEX to contents of the smart platform such as the Android and the iOS. The automatic mobile contents converter system helps minimize the amount of time and cost required in servicing contents to different mobile communication companies by promptly converting platform-specific-contents to run under smart platforms. Also, the automatic conversion and servicing of existing contents increases the reusability of these contents and also the productivity of new contents thereby offering users with a more variety of game contents.

In this paper, a mobile quiz system using SMS has been developed, which can be conveniently used on the spot of education. The system immediately not only provides each individual student with the results of his/her quizzes but also a instructor with the statistics of the results by SMS. Field tests of the quiz system have shown that it can be effectively used as a good teaching tool for teachers getting immediate feedback from participants in the lecture and adjusting teaching level as well as for inducing more interest in learning from participants and raising their concentration on the class.

최근 모바일 단말 기술과 정보통신 기술의 급격한 발달로 국내외 이동통신사들은 새로운 킬러 콘텐츠로 주목받고 있는 모바일 3D 게임을 앞 다투어 제작 및 서비스하고 있다. 모바일 3D 게임의 경우, 용량 증가로 인한 데이터 통신비 부담을 줄이기 위하여 PC 다운로드 S/W을 통한 다운로드 방법이 제공되면서 불법 복제 우려에 대한 관심이 높아지고 있다. 현재 불법 복제 방지와 관련하여 GVM/GNEX 인증 모듈이 적용되고 있으나, 모바일 3D 콘텐츠에 대한 저작권 보호 기술 및 워터마킹 기술을 적용함으로써 콘텐츠 접근제어 및 불법배포 추적을 동시에 달성할 수 있다. 따라서 본 논문에서는 모바일 3D 콘텐츠의 저작권 보호를 위하여 익명 Buyer-Seller 워터마킹 프로토콜 상에서 3D 콘텐츠 내의 공간영역 및 암호화 영역 내에 다중 워터마크를 삽입하는 방법을 제안한다. 성능평가를 위한 비가시성 및 강인성 실험을 통하여 본 제안 기법의 콘텐츠 접근제어가 가능하며 비가시성, 강인성 면에서 우수함을 확인하였다.
