In this paper, we implement the multimedia remote control system by using existing internet service or wired online. We also provide user-friendly convenient environment with developed application program named EzPlay and PC-EPG. The multimedia remote control system consists of integrated wireless transceiver of PC and TV connected USB type and the users can easily use lots of contents because EzPlay program provides appropriate UI mode on the PC and TV screen. The unposed system can operate real-time playing, reserved video receding and data storing function using internet mesh based on signal detecting control theory. The PC-EPG system is implemented by server/client web program and the client program based on visual C++/MFC processes data storing in client computer through TCP/IP. It also provides intelligent function that constructs database according to user's preference.

This paper describes the dual system technology of PC based control system at steel plant. Because PC is developed to be used in wide area such as Office Automation, Personal, It is cheaper and more portable than the present process control system, but is less stable and less reliable. In this research, We gathered the fault example of a general process control system and steel process control system, analyzed the cause of fault and decided the target fault that took over in our proposed system. The proposed PC based system is the dual system that has a shared RAID system connected by SCSI bus between two systems. In order to assist system reliability, we proposed watchdog manager to monitor ...

"Samsung Composite Shear Wall System" has its basis on "Samung Able System". "Samsung Able System" has some problems not only in the connection structure but also in waterproofing and soundproofing. We developed "Samsung Composite Shear Wall System" in order to solve these matters and expand PC system. "Samsung Composite Shear Wall System" is the compromise and complement of all the merits of full PC, half PC and in-situ concrete system.

The encryption of a file on a PC before saving can maintain security of the file. However, if the key for the encrypted file is lost or damaged, the encrypted file can not be decrypted, resulting in serious economical loss to the user or the user group. In order to minimize the economical loss a secure and reliable key recovery technology is required. Presented in this paper is the development and evaluation of PKRS (PC based Key Recovery System) which supports encryption and decryption of file and recovery of the encrypted file in emergency. The encapsulating method, which attaches key recovery information to encrypted file, is applied to the PKRS. In addition, the PKRS is developed and evaluated according to the requirements of Requirements for Key Recovery Products proposed by NIST and requirements of Common Criteria 2.0 to prove the safety and reliability of the information security system. This system is applicable to a PC and can be further extended to internet or intranet environment information system where in encryption and recovery of file is possible.

Because the construction type SFRB is completely different in comparison with that of RC apartment the construction and work process, which are currently used, have to be changed. The main purpose of study is to analyze the difficulties of this construction and to apply the technology for other construction area. In this study, it is investigated to the problems of construction for SFRB and the construction method of PC panel fabricated on SFRB in Yongin goosng. Later, it is estimated prefabricated method had an great effect on PC panel System as lower cost and shorter schedule in SFRB. The Precast concrete framed System has many merit than the reinforced concrete structures system at constructability, structural safety and quality, therefore, it will be widely applied at parking structure in the future.

Recently, the robot control systems are required to be more flexible and intelligent in order to execute more complex and delicate tasks. As an approach to such system, a PC-based robot control system is presented in this paper. The axis controllers are independently designed for each joint of robot manipulator and are supervised by a personal computer. Therefore, the almost system program including the control algorithm can be easily developed and modified in the PC's environment. This proposed control system was successfully applied to 4 axis SCARA-type robot and the associated S/W modules were developed. We can construct sensory robot systems by simply connecting the sensing devices to the PC and the study on this now being progressed.

In this paper we introduce the implementation of PC-based receiver platform to verify T-DMB middleware APIs. Recently, generic APIs in T-DMB middleware (called DMB MATE API) have been designed to enable inter-operable applications to be downloaded from both the broadcast and telecommunication networks in advance and to be executed on T-DMB receivers from any manufacturers. We also verify the designed MATE API through execution of several applications at the PC-based receiver. In future, the T-DMB middleware verified in PC can be implemented at various receivers such as T-DMB phone and portable T-DMB receiver.

In recent, the researches on driver assistance systems have been actively performed with development of vehicle industry. AVM(Around View Monitoring) Systems, a part of these systems, have been researching and developing. Existing AVM systems have been developed in the forms of embedded systems or a SoC (System on Chip) to provide view around vehicle in real time. However, if Car PC is equipped with in vehicle, AVM can be developed using only software without additional cost. In this study, we implemented AVM system which provides location information by adding the informations such as latitude, longitude and speed to functions of "Car PC" based AVM system. If storing function is added to the AVM system implemented in this study which provides location information, the system with storing function can be used as AVM black box system.

This paper describes research results that 2-D contents, which display in smart phone or tablet PC to be able to see the 3-D stereoscopic by use projection technique. For this research, we have construct four brown-glass into pyramid shape, project each of the four LCD monitors that output from the PC screen into of the four inverted pyramid-shaped mirror and display the 3-D image to the center of the mirror system. For the test, We use tablet PC and server PC(desktop PC) connected by wireless network, tablet PC select contents which is displayed in the server PC, and displayed selected contents into the 3-D image to the center of the mirror system. Through the test, we have showed that it is possible to display 3-D stereoscopic to the 2-D contents by use projection technique. Although, display image is depending on the observer's viewing angle.
