  • Video quality is degraded by codec and transmission error. By analyses video pattern through NR(no reference) method, we get to aware that telephony video has particular blocking and blurring pattern and NR is suitable for telephony video quality testing. So NR will make contribution to enhancing video quality and monitoring video quality in advance.

  • The subway station platform is designed in high platform for quick getting in/out which is against ordinary train platform. Out of 370 Metropolitan subway station platforms, subway stations which have cured platform are about 38%. In these cases, as the distance between subway and platform would become longer, handicapped people's wheelchairs, baby carriers and old and feeble people can feel uncomfortable when they are getting in and out Also, passengers often fall into track because of the height difference between high platform and track. And if passengers go down on track to pick up something fallen, they sometime fail to climb up and happen to hit against subway. To solve out these kind of inconveniences and prevent accidents, we have developed subway station high platform safety system and finished tests. This safety system is consisted of safety block, screened door and safety wall. This study explained the composition and function of this system and presented the test result to identify its performance.

  • Kinematic and dynamic characteristics of a Stewart platform based parallel manipulators are fixed once they are constructed. Thus parallel manipulators with various configurations are required to meet a variety of applications. In this research a parallel manipulator with variable platform (PMVP) has been developed, in which the length of the arm linking the platform center to the platform-leg contact point can be varied by an actuator. The workspace of the PMVP is larger than that of a traditional Stewart platform and especially the range in which the maximum orientation angles can be maintained is significantly expanded. Furthermore, the characteristics of force and moment transmission between the legs and platform can be adjusted to meet the requirements of various tasks. Kinematic and dynamics analysis was performed to verify the usefulness of the PMVP and the actual hardware was built to demonstrate the feasibility.

  • In order to implement e-trade infrastructure through the radical innovation of trade process, e-trade platform which is called 'uTradehub' has been developed for three years. After pilot operation of this platform in 2007, the formal service of e-trade such as logistics, customs and foreign exchanges had been provided in 2008. However, the usage of e-Trade platform is not the level of users' satisfaction because trade-related communities have not actively participated into e-trade platform and several functions with users requirements are necessary to develop additionally. In this regard, there are strong demands to suggest some strategies for application and usage proliferation of e-trade platform. Therefore, this paper would like to evaluate the current status of e-trade platform service and usage by the theoretical consideration of preceding researches and practical analysis of statistical data. Then, it will explore several service improvement ideas in terms of system supplementation and integration, electronic documents standardization, radical change of using fee, global connection, user oriented education and advertisement.

  • In this paper, we design a mobile phone based remote control system for PC using SKT WPAN platform and compare the presented platform with that of Windows Mobile. The usability of WPAN is one of the main issues which should be considered for the ubiquitous services. For easy development and easy use of the WPAN applications, SKT WPAN platform provides abstract WPAN APIs and WPAN Application Manager for ubiquitous services. In this paper, we implement a remote control application using the WPAN platform and show the validity of the platform comparing with other platforms. In the implemented application, we use WPAN abstract APIs on the mobile phone side and a general Bluetooth APIs on the PC for a connection between phone and PC. Through the implementation and comparison, we show that the WPAN application can be easily developed with WPAN platform.

  • In this paper, we designed a platform-based $ERP^+$ system, which integrates ERP system and SCM system. With platform-based technology we can connect online and offline platforms, enterprise management systems, and government systems. In our research, first we examined the problems of the existing ERP systems, and second we discussed all basic tasks of our $ERP^+$ system. We also designed several modules for this platform-based system and system network. Our results showed that a platform-based $ERP^+$ system can effectively manage the information and the human/material resources, by using O2O (online to offline) technic. Even different systems can be integrated effectively. It can reduce the costs of enterprise management activities, enhance the enterprise competitiveness.

  • Learning Power Electronics is essential in both electrical and electronic engineering fields and the introductory courses are similar in many universities. Taking this premise into account, an educational computer-aided platform for power electronics will be presented in this paper. This educational platform includes an e-book, a set of power electronics animations, Java simulations, as well as several hands-on training sessions. The main advantages of this platform are twofold. First, all necessary teaching tools are combined on a single platform. And secondly, access to this platform is available free of charge and with no complicated registration requirements. In addition to traditional teaching techniques, the use of this platform has demonstrated an increase in student participation and has consistently improved their academic performance. Data consist of surveys, which guarantee both reliability and validity through psychometric techniques.
