The roll Pass design is one of the most important processes to design the whole equipment of the rods and bars rolling system. In this study, the roll pass design program named TollRo(Rolling Factory Organizer) was developed. conventional methods to design roll pass were analyzed and a new algorithm to design the dimension of the intermediate groove was introduced. Object oriented programming technology was implemented in this design program. It comprises GUI(Graphic User Interface), function of automatic pass design, function of modifying pass schedule and database of material properties. The developed program can be used to design roll pass with consistency for the rods and bars rolling system. The man-hours for the whole design can be drastically reduced. The design parameters of rolling system can be extracted quickly by this program.

Due to the rapid growth of ship building industry and increment of ship construction in Korea, several hundred thousand of lifting lugs per year, have been installed at the lifting positions of ship block and removed after finishing their function, therefore, appropriate design system for strength check or optimal design of each lug structure has been required in order to increase the capability of efficient design. In this study, design system of D-type lifting lug structure which is most popular and useful in shipyards, was developed for the purpose of initial design of lug structure. Developed system layout and graphic user interface for this design system based on the C++ language were explained step by step. Using this design system, more efficient performance of lug structural design will be expected on the windows of personal computer.

The interaction effects of the cognitive style and the presentation order of learning material was explored in the study. Visualizers performed better when the graphic information was presented prior to the verbal information, whereas verbalizers did better when the verbal information was presented prior to the graphic information. The results of the present research have practical implication of personalized multimedia design based on the learner's cognitive style. The results also have suggested that the cognitive load of a multimedia material can be varied depending on the compatibility of the cognitive style and the material.

FM screening has been praised for its apparent resolution advantage over conventional AM screening. FM screening is also known for its criticalness of film output and difficulties in the proofing stage because of the microdot formation. However, FM screening is not a well understood process from press performance point of view. This study was carried out for the purposes of introducing the availability of hifi-offset printing to domestic printing industries and evaluating the print qualities between 300lpi AM screen and FM screen with the equivalent sized microdots to 4-5% dot area of the 300lpi AM screen, together with comparing with 175lpi AM screen representing a conventional printing. Solid density, dot gain, color gamut and some other quality properties were measured and discussed.

Halftonig is a technique to create the appearance of intermideate tone levels by controlling the spatial distribution of the binary pixel values. Recently, many printing devices such as image setter, inkjet printer, laser printer and facsimile, generate image, they require the technique. Ordered dither is achieved comparing the gray scale image to periodic array. This method is fast, but it occurs periodic patterns. Conentional error diffusion generates a good image. But processing speed is very slow and appeares worm artifacts in middle tone scale. To improve it, Bns(Blue noise Screen) is developed based on Gaussian distribution. In this paper, we discribe methods to design BNS based human visual characteristics and to improve blue appearing at edge area of image by USM(using unsharp mask).

Sine CAM structure is regular structure as that of RAM of PLA, CAM generator program is easy to implement. This program outputs CAM layout in the form of CIF(Caltech Intermediate Format) and graphic display program is debugging or displaying CAM generator output, which are implemented on PC/AT with MS C(5.0) graphic library and C language. CIF parser is programmed with YACC(Yet Another Compiler Compiler) and LEX (Lexical Analyzer) in order to flat the CIF data. For the purposed of plotting the layout output using ROLAND XY plotter is developed. By combining these program described above, from CIF generation to layout plotting can be executed on pull-down menu according to user's option.

The object of this research is to develop an Interactive Computerized Graphic Program for graphic output of velocity, acceleration and motion range of body-task reference point (e.g., C.O.G., joint location, etc.). Human motions can be reproduced by scanning (rate = 60Hz) the vidicon image, and the results are stored in an Apple II P.C. memory. The results of this study can be extended to simulation and reproduction of human motions for optimal task design.
