To enhance the educational effect of Multi-Joint Robot have to easily develop motion through the control software. The traditional way of development technique for multi-joint robot is educated with very complicated implementation, but our motion creation tool can be possible to do the creative activity for controling robot movements with ease. This paper mentions to develop the motion creation tool for easily and quickly programming the motion control of multi-joint robot on the educational program. With this tool we easily and exactly provide the education of robot program. In this paper, our suggested tool could not only evade the traditional way of a complicated control program using programming languages but also control easier the robot than the GUI(Graphic User Interface) programming centered on the user's convenience. Additionally, the robot motion's implementation is possible applied with microprocessor experimental equipment educationally to practical use.

In this paper, we develop the image transfer remote maintenance monitoring system for hand held device which can compensate defects of human mistake. The human mistakes always happen when the worker communicate information each other to check and maintenance the equipment of the power plant under bad circumstance such as small place and long distance in power plant. A worker couldn't converse with other when in noisy place like Power plant. So, we make some hand device for handy size and able to converse in noisy place. The developed system can have improvement of productivity through increasing plant operation time. And developed system is composed of advanced H/W(hard ware) system and S/W(soft ware)system. The H/W system consist of media server unit, communication equipment with hand held device, portable camera, mike and head set. The advanced s/w system consist of data base system, client pc(personal computer) real time monitoring system which has server GUI(graphic user interface) program, wireless monitoring program and wire ethernet communication program. The client GUI program is composed of total solution program as pc camera program, and phonetic conversation program etc.. We analyzed the required items and investigated applicable part in the image transfer remote maintenance monitoring system with hand held device. Also we investigated linkage of communication protocol for developed prototype, developed software tool of two-way communication and realtime recording skill of voice with image. We confirmed the efficiency by the field test in preventive maintenance of plant power.

This paper describes the development of automatic shape design program for spur gear. It produces automatically third-dimensional surface and solid model used in CAD/CAM system with inputting simple measurements. This program can maximize user's convenience and get surface and solid model quickly as accepting GUI(graphic user interface). Automatic shape design program for spur gear was developed by Visual LISP, a developer program. Besides, a geometrical method and a mathematical algerian are used in this program. Use frequency of a fine spur gear is on the increase recently and manufacture process of this gear is heat treatment after press processing with molding. In this press processing, the upper punch portion of a fine spur gear shape is drafted by CAM. Therefore, estimated that surface and solid model of spur gear used to CAM are needed in this research. In this research, after 2 ㎜ gear was modeled by auto shape design program, the upper punch portion of a fine spur gear was manufactured as giving third-dimensional model to CAM software and then, displayed the result as applying to press process.

Computer development and new printing technology allow us to express a new type of digital textile designs those were not possible in the past. In this study, watercolor overlaying effect of various colors was tried using airbrush tool in Photoshop program. Photoshop program is a powerful graphic tool and can be used in textile design area to generate various types of designs. Woven texture was also applied to the design to give yarn dyed effects or rich appearance. Photoshop program was also used to develop woven texture without the help of the professional textile CAD. Photoshop channels enables the designers to apply various textures to the image. Plain weave and houndstooth were applied in this study. Colorways of the developed designs having watercolor effect and woven texture by applying Photoshop color adjustment function. Quick and simultaneous changes of colors were possible using this method. The developed textile designs were printed by transfer DTP. Successful textile design prints were expressed and showed watercolor overlaying effect and woven texture. The printed textiles show a little brighter color, and therefore, sample printing is recommendable in case of color sensitive production.

We parallelized WRF major physics routines for Nvidia GP-GPUs with CUDA Fortran. GP-GPUs are originally designed for graphic processing, but show high performance with low electricity for calculating numerical models. In the CUDA environment, a data domain is allocated into thread blocks and threads in each thread block are computing in parallel. We parallelized the WRF program to use of thread blocks efficiently. We validated the GP-GPU program with the original CPU program, and the WRF model using GP-GPUs shows efficient speedup.

This program is developed to design Prestressed Concrete Cylinder Pipes (PCCP), Fittings and Thurst Blocks and to manage drawings, quantity calculations and calculation data, using Graphic User Interface(GUI), which is capble of not only reducing the time taken to design, but also enabling the user to achieve such a design even when operator has no theoretical knowledge of that design while only having knowledge of data inputting and outputting. PCCP is used in water transmission popeline of the Great Man-made River Project. In domestic area, PCCP is used for water cooling systems of Uljin and Youngkwang nuclear power. In abroad, especially in the United States and Canada PCCP applies virtually every metropolitan area with raw and treated water.

Drawing pneumatic circuits by hand and searching for the error when the circuit is not properly constructed are very difficult. In this paper, a graphic simulation program for drawing and evaluating pneumatic circuit systems was developed. The porgram is menu-driven style and pneumatic circuit can be easily drawn by selecting the pneumatic components from the menus. Simulation of the motion of each pneumatic component and testing of whether the circuit is constructed properly are possible with the software. This program was written in Turbo Pascal and also used the Turbo Graphix Toolbox. The system hardware requires IBM PC, XT, AT or compatibles, and Hercules Card.

This study is to develop the interactive program for work-cell layout of SCAPA type robot using PC. To make the program interactively, we made use of the software which have the function of menu, dialog box, and graphic. By using the mouse, we can progress the program quickly and easily. It has 2 1/2 dimension and provides that one can layout the elements(robot, peripheral device, and etc.), create the work path, and calculate the robot cycle time. By comparing with cycle times of any number of work-cell layout for the same work, we can evaluate work-cell layout and select one work-cell layout to be considered optimal one which has the least cycle time.
