This paper presents a new architecture, called "Power Electronics Remote Wiring and Measurement Laboratory (PermLAB)", that translates a common gateway interface (CGI) string from a remote web user to a web server connected to a 3-dimension switching matrix board, can be used to switch on and off, and to control a cluster of instruments and components. PermLAB addresses real-time connection, switching, and data acquisition over the Internet instead of using simulated data. A software procedure uses a signature system to identify each instrument and component in a complex system. The Web-server application is developed in HTML, JavaScript and Java, and in C language for the CGI interface, which resides in a controller portion of LabVIEW. The LabVIEW software fully integrates the Web sever, LabVIEW data acquisition boards and controllers, and the 3-dimensional switching matrix board. The paper will analyze a half-wave rectifier (AC - DC converter) circuit connected over the Internet using the PermLAB. PermLAB allows students to obtain real data by real-time wiring of real circuits in the laboratory using a "virtual breadboard" on the Web. The software for the Web-based 3-dimensional system is flexible, portable, can be integrated into many laboratory applications or expanded, and easily accessible worldwide.

TV is Device best known to everyone. Showing off a smart TV in the TV industry has recently become a new blue ocean in the TV market. As with other smart devices, smart TV is also an important factor is a very important application. In this paper, by using the Samsung SDK to application of Web-based that can be used in smart TV environment of Samsung, we have developed a board game that has been created based on JAVA SCRIPT, CSS, and HTML. Rules of the game of the board game format using the dice is easy, this application is a four-person game that also men and women of all ages who enjoy.

The Satellite OBC(On Board Computer) manages critical functionality such as satellite attitude control, fault management, payload management, command/telemetry processing etc. The OBC consist of various modules. Each module perform mission critical operation. So all modules designed as hot or cold redundancy architecture. The redundancy design gives a guarantee high reliability and it allows normal operation of satellite using reconfiguration capability. In this paper, introduces reconfiguration unit operation and describe the results of testing in the ETB.

In optimum design of packaging container for bulk materials, minimum board area, compression performance and distribution efficiency must be considered. In this study, mathematical models for minimum board area (RMA), compression strength (CS) and maximum compression strength per unit board area (MCSA) of container as algorithm for optimum design of packaging conatiner for bulk materials were developed as follows : RMA=f(V,D), ${\alpha}_{RMA}=f(V,D)$, MCSA=f(V,D), and ${\alpha}_{MCSA}=f(V,D)$. In order to develop these models, compression test according to various dimensions of container and response surface analysis for minimum board area, compression strength, and maximum compression strength per unit board area of container were carried out. In developed models, volume and depth of container were principal independent variables. Through the verified results for these models, optimum design of packaging container on the design conditions and limit conditions was possible. These models might be used in developing optimum design software of packaging container for bulk materials.

If an optimum design technique is applied in the design of packaging container for bulk-type products, merits on the side of not only economic and compression performance but distribution efficiency are expected. Accordingly, minimum board area (mRBA), compression strength (CS) and compression strength per unit area (mCSPA) are important design parameters in optimum design of packaging container for bulk-type products. In this study, mathematical models for mRBA, CS and mCSPA of container as algorithm for optimum design program were developed. In order to develop these models, compression test by various dimensions of container and response surface analysis for mRBA, CS, and mCSPA of container were carried out. In the developed models, volume, W/L ratio and depth of container were principal independent variables. On the found of these models, optimum design program having faculties of outward and inward optimum design and information design was developed. Though the packaging specifications are same, required board area, board combination and cost of the corrugated board required container manufacture were greatly different by boundary conditions in outward design. Moreover, about 6.3∼10.1% in weight of container was lighter, and about 13.2∼25.6% in cost of container was reduced when the program was applied for 2 kinds of bulk-type products.

By the use of open source and 16bit Microcomputer, IDB(Integrated Development Board) for embedded technical education was designed and developed. Based on 16bit MCU H8/300H, LED, LED Matrix, motors, sensors and various I/O circuitry, and the connection to a computer via the SCI, and $16{\times}2$ character LCD was designed and implemented on IDB. In addition, the software development environment was build by the assembler and H8 C compiler which is provided to the open-source software. And memory expansion was considered to include TRON(Real time OS) and uClinux. To verify the developed board, IDB was fabricated by PCB machine, and the fuction was confirmed by the basic I/O control program.

The COMS flight software is implemented by ADA language and the high level application program language (APL). The APL is used to implement the Interpreted Program (IP) functions which are running on the processor. The IP functions have been developed for the payload management and monitoring with the automatic on-board operational procedure. The IP allows an easier re-programming if necessary. The ground can load or unload IP separately from ADA code in the RAM flight software. The uploaded IP is interpreted and executed by the Interpreted Program Environment (IPE) which is one of the functions implemented in the RAM flight software. In this paper, we introduce the IP and IPE function.

Surface mounters are used to mount the parts of electronic products on PCB(Printed Circuit Board. Those machines rely on high precision, high productivity, and software for accomodation of use. In this paper, two algorithms and a software which can give the users the acco-modation and high productivity for rotary type surface mounters are presented. The algo- rithms for development of of the software consider all factors which affect the effeciency of the operation. And the interface between user and machine for the accomodation of use can be achieved through the developed software.

If optimum design technique is applied in the design of packaging container for bulk materials, merits on the side of not only economic and compression performance but distribution efficiency are expected. In this study, on the ground of the optimum models for required board area and compression strength performance, optimum design program having faculties of outward and inward optimum design and information design was developed. This program was composed of input module, output module, database and management module, and calculation module. Though the packaging specifications ars same, requied board area, board composition and cost of container were greatly different according to exterior packaging conditions. Also, about 12% in weight of container was lighter, and about $13{\sim}17%$ in cost of container was reduced when the program was applied for 2 kinds of bulk materials.

In order to verify normal operation of satellite OBC(On Board Computer), it is essential that processor monitoring and debugging. So we are using the GRMON of Aeroflex Gaisler. It provides a lot of features for debugging of LEON processor but we can't use that features on the NGSCB(Next Generation Spacecraft Computer Board) except a few things. So the cost-effectiveness is very low. And for hardware fault injection, we are using a method of modify satellite flight software, because we can't modify GRMON. This method can not guarantee normal operation of the satellite flight software. So in this paper we were developed the processor monitoring and fault injection tool for NGSCB.
