  • In this paper we tried to overcome the limit of contents which occur when we implement the augmented reality technology adapted application on commercialized mobile system. First of all, we checked the requirement analysis of exclusive mobile system to support augmented reality. And then we designed and realized the mobile system based on this facts. Also we embodied augmented reality application based on NyARToolkit which assists augmented reality techniques. Finally the implemented contents operated properly in our exclusive mobile system. Consequently we confirmed the suitability and validity of our system through above test.

  • This paper presents the design concepts and the system architecture of a mobile exchange for CDMA Mobile System. The paper also discusses complex subsystems in this system and design concepts of these subsystems. To evaluate the performance of the CDMA Mobile System, we have performed a computer simulation based on the framework of the mobile exchange. Simulation results are presented in terms of network traffic load (call attempts per second) and database performance requirements (transactions per second.)

  • This paper presents a frequency selection algorithm for minimization power consumption of processor in Mobile System. The proposed algorithm has processor designed low power processor using clock gating method. Clock gating method has improved the power dissipation by control main clock through the bus which is embedded clock block applying the method of clock gating. Proposed method has compared power consumption considered the dynamic power for processor, selected frequency has considered energy gain and energy consumption for designed processor. Or reduced power consumption with decreased processor speed using slack time. This technique has improved the life time of the mobile systems by clock gating method, considered energy and using slack time. As an results, the proposed algorithm reduce average power saving up to 4% comparing to not apply processor in mobile system.

  • In the recent a mobile internet makes a change in internet business. The mobile internet service is resulting in M-commerce. Even if M-commerce provides only information service, there will be much possibilities to make applications in various areas such as, delivery service, trading service, banking service etc. in the near future. Delivery service requires many steps in processing, originally. This study is designed to implement a mobile system which makes short in delivery process. It includes that a delivery man receives a signature on a paper and input data at the delivered place by using PDA at hand. The mobile system will be contributed to shorten delivery speed. It is proposed to implement the mobile office system for improving service efficiency in the business of delivery service.

  • This paper will propose the efficient method that should be designed to utilize the design pattern of GoF(Gang of Four) for implementation of LBS(Location Based Service) mobile system. The design method proposed by this paper can design and implement system interface using creational patterns, structural patterns and behavioral patterns of design pattern from the user and mobile system viewpoint. The design method using design pattern can show increasing reusability of module and software, abridging the development time, minimizing the maintenance and decreasing the efficiency of memory of system to software development. Therefore, we used a design pattern in order to change the middleware applying geographic information system from mobile environment. Finally, the mobile system applied to design pattern shall contribute to showing high stability and reliability, improving reusability and scalability of module and software and developing efficient LBS mobile system.

  • The efficient maintenance and management of steep slopes often require excessive professional resources and quantitative investigations. Therefore, it is important to develop technology for objective scientific site investigations and quantitative evaluations of steep slopes. This study proposes a 'Mobile System' for steep slopes in order to improve the effectiveness of site investigations compared with conventional methods using anevaluati on table. By analyzing site investigations and desktop studies, the required software and hardware are identified to develop the 'Mobile System', consisting of a 'Field Information Input System' and an 'Analysis System'. The applicability of the system is verified by its application to an area with steep slopes affected by debris flows. The use of this system is expected to increase the efficiency of maintaining steep slope sand to reduce the time and resources required.
