Generally, bridge designers must consider variable factors in design of bridge-structures. For this reason, it was difficult to make a design program till now. However, the rapid development of computers turns it into a possible one with considering complex factors and the advance of computer's language make us design programming. When we use the automatic design program including structural analysis(FEM), we can save the time and effort. Additionally, the automatic design program was generated to reduce the man' errors. Therefore, in this paper, the automatic design program of the Prestressed Concrete Slab Bridge was developed. This design program will support bridge designers with time that they can spend on a creative and efficient duty for development of design.

Kinematic analysis was made on a gear type high speed planting mechanism for riding-type rice transplanters. The kinematic equations thus derived were computer coded to simulate its motion characteristics such as a planting locus, velocities and accelerations of gears and planting knife, etc. Using the simulation program a sensitivity analysis of design parameters was also carried out to determine their effects on the planting performance. Of the design parameters the eccentricity of the gear was found most influential.

The liquid ejector, having no moving, lubricating and leaking parts, is widely used as the various pumps because of its high working confidence and simplicity. Previously, computer aided design program for the small-sized liquid ejector was developed based on the one-dimensional flow analysis and the systematical laboratory level experiments. Through the present research, it is confirmed that the previously developed computer program to getermine the main design dimensions and to calculate the expected performance curve is satisfactorily applied to design the large liquid ejectors.

The major advantages to use CAD System are that it reduce time and effort to manufacture products, and also can demonstrate the condition of the final product prior to the actual manufacturing process of the selected design using the simulation programs in CAD system. Specially in weave design, for use as Computer-Aided Weaving system, the complicated Dobby weave can figured out easily through calculating the complex weave plans of multi shafts. As to one of dobby weave structures, Supplementary warp is the warp threads which are in addition to the regular warps of the woven fabrics, and used for decorating the band or expressing some patterns. The purpose of this study is to research the weave design of Supplementary warp using Computer-Aided Weaving system, which is dobby weave design program of Weave Point. For performing this design study, it was researched the classified woven fabrics depending upon weaving processing, Computer-Aided Weaving system, and the characteristic of Supplementary warp fabrics. On the basis of the theoretical research, Supplementary warp was worked for the 24-shafts AVL computer dobby loom that applied to the various patterned images. The design work was done by Weave Point program of dobby weave, and simulated to fabrics before woven into the computer dobby loom. To see the visual images of fashion items, these simulated bobby fabrics were processed by three-dimension modeling through YoungWoo CNI CAD system. All the patterns of the Supplementary warp in this study could be applied for decorating the fashion clothing and accessories.

In this paper, arm-type lifting mechanism which is attached under the frame of truck is analyzed. The three types of motions which are divided into rotation, pure lifting and automatic tilting motions are analyzed kinematically. These motions are visualized by computer graphics using Visual Basic. This program will be used for designer to demonstrate the arm-type lifting mechanism before making real machines. Also this program can change design parameter interactively.

In this study, a computer program was developed which generates automatically a drawing of the forging design in axisymmetric hot-forging of steel. The program designs a forging envelope from a machined part geometry according to forging design rules: parting line, draft angles, fillet and corner radii, minimum web and rib thicknesses. For the purpose of verification, the program was applied to a machined part from a factory. It was found that the generate forging design agreed well with the actual one used in the factory.

The Wisconsin Department of Transportation currently has a Datalog Information System which facilitates the collection of geometric characteristics at every 0.01 mile high way section. The objectives of this study are to develop the plan and profile drawing of a highway section utilizing the Datalog Information system and to develop a methodology of investigating the safety aspects associated with the highway section being considered. For this purpose, two of the highway design elements, the minimum stoping sight distance as well as passing sight distance based on the AASHTO requirements, were applied in this study. A computer program was also developed to facilitate the data processing activity. The results from the computer program and from a manual analysis which adopted the identical methodology used in the computer program were in a good agreement. a few discrepancies between the two results were due to the data collection error and they were believed to be negligible. Using the computerized methodology developed in this study one does not need the plan and profile drawing to investigate the safety of a highway section, which appears to be an essential progress to the Computer Aided design and Draft in highway engineering field.

Most of designers use applied software of computer programs instead of traditional tools such as brushes, poster colors, etc. for drawing and designing. For example applied software programs for design are applied the workings printing, presentation, movie, animation, character design as well as industrial design. Especially, quality of applied software programs in the field of visual communication design influence on the design results in future. Therefore, many college attempt to invest budget to inhrence the quality of software program in design education. However, effectiveness of investment is lowered due to the professional lack of software knowledge. This study tries to explore how the investment for software program in visual communication design becomes more effective, and to suggest how the order of software program, design curriculum through the affective computer usage in design education will be more useful than now. By comparing and contrasting the different cases in the computer environments of the colleges, this study was processing, the result of this study will contribute to the design education of visual communication.

Nowadays computer technology is being applied in various areas of apparel design. In particular, since the task of pattern making is to be performed by a set of predefined drawing rules, the effect of computer application in pattern making will be significant, There have been a large number of studies on pattern making program. For instance, the previous studies have developed computer programs for pattern making of women's wear, men's wear, children's wear, Han-Bok, etc. Most of them have focused on the development of computer program for a particular kind of apparel only and, however, have disregarded the feasibility of developing a multi-purposed computer program so that is just can be modified to adopt for various styles. For example, by widening the hem-wide of the basic H-Line skirt and then connecting its waist line and widened hem-wide, we can draw the A-Line skirt. Therefore, we have developed a program which can make a pattern for the basic skirt and can mae, with a slight change of he program, other patterns for various style as well. The objective of this paper is to identify and organize modules which will be used for developing a general pattern making computer system. This general pattern making system is a computer program by which we can draw a variety of apparel styles. This system is restricted to skirt pattern making only. there presentation scheme used in organizing these modules is an AND-OR tree, the one being often used in representing a complex problem in artificial intelligence domain.
