In this study, we develop automatic design program, which create 3D model of spur gear and helical gear used VisuaILISP and create helical gear in the CATIA using 2D profile of gear. This model become the standard model, which give not only in itself mold information but also computer processed product with measuring date. Spur gear require mathematical examination of involute curve and trocoidal fillet curve. Automatic design program, which have a mathematical development create the profile of spur gear.

This study was designed for automated pattern drawing and grading a man's Durumagi, Korean traditional coat in order to reestablished and grade the pattern by Apparel CAD SYSTEM. For the study, AM-250 systems of Gerber as the computer and Macro program as the automated drawing were used. Also, PDS(Pattern Design System) was used for the grading of the original Durumagi pattern. Results were followings; First, the size data that could be standardized by reestablishing the pattern of a man's Durumagi by each size was presented. Second, The pattern was developed by each size. Third, new design was propose for mass production with the traditional design of the DURUMAGI Fourth, The time for making DURUMAGI pattern and the cost through the automated drawings by using the Macro program were reduced. Moreover, was presented the basic data for a ready to made garment like the Western garment. Five, A man's DURUMAGI by CAD System was graded that could be applied to ready to made Hanbok

Proper PCR primer design determines the success or failure of Polymerase Chain Reaction (PCR) reactions. In this project, we develop GENE-PRIMER, a genomes specific PCR primer design program that is amenable to a genome-wide scale. To achieve this, we incorporated various parameters with biological significance into our program, namely, primer length, melting temperature of primers Tm, guanine/cytosine (GC) content of primer, homopolymeric runs in primer and self-hybridization tendency of primer. In addition, BLAST algorithm is utilized for the purpose of primer specificity check. In summary, selected primers adhered to both physico-chemical criteria and also display specificity to intended binding site in the genome.

We developed a pattern drafting computer program using a popular CAD program for the purpose of the automatic manufacturing and education based on the concept of the easy -order-system which can easily reflect body characteristics and design favors of individuals to the ready-made clothing. The programs were written in Auto LISP which can utilise most of frictions of the Auto CAD, and the result of the design for an full-pleated skirt was shown. Also, we devised an easy way to set the location of reference points by inputting of tangential angle only for the use of the cubic spline curve which can represent body shape very well. Finally, by marking down all of symbols needed in manufacturing process, we completed the automatic pattern drafting program to make it useful as an industrial pattern without any amendment or correction in cutting and sewing operation.

This monograph is based on the purpose of exploiting the program, which let designers to easily compile the input data of a widely used FEM analysis program, SAP90 - one of structural analysis programs, and making it easy to design slab bridges by studying more efficient analysis method with optimization method. The knowledge of position at which a maximum moment occurs is helpful to do a practical design. Seeing that more time and capital should be invested when engineers depend on manual work in the process of making input data repeatedly, the automatic process would increase the degree of reliability and productivity.

최근 IT분야에서는 빅 데이터를 활용한 인공지능이 크게 대두되고 있다. 이와 같이 빅 데이터를 효과적으로 처리하기 위한 서비스 또는 기술에 대하여 다양한 연구가 진행되고 있다. 교육분야에 있어서도 학생들에 대한 빅 데이터가 존재하나 이러한 데이터를 단순히 수집, 조회, 저장하는 단순처리과정을 거칠 뿐이다. 향후 인공지능이나 기계학습, 통계분석 등을 폭 넓게 이용하여 교육분야의 빅 데이터에서 의미 있는 규칙이나 패턴 및 관계를 찾아내어, 실제 학생들에게 도움이 되는 데이터를 생산 지능적인 활용이 요구되고 있다. 이에 따라서 본 연구에서는 학생들의 수업 관찰을 통한 데이터를 의사결정트리 알고리즘을 이용하여 학생들의 진로를 예측하는 프로그램을 설계하고자 한다. 진로예측 프로그램을 통하여 학생들의 상담에 활용 진로를 제시하고 또한 희망 진로에 따른 수업 태도 및 방향을 제시하는데 도움이 될 것으로 사료된다.

It is essential to know climatic characteristics of the site for energy efficient building design. However, it is difficult to obtain a climate data. Even though the climate data is obtained, it is difficult to be applied to the building design since it is usually consisted of just series of numbers. Also, designers cannot know the effective climatic design strategies suitable for the site with ease. Thus, this study aims to develope the climatic design tool working on the personal computer operated by windows 95/98/2000/XP. WYEC weather data and building bioclimatic chart are adopted for the climate analysis. Climatic Characteristics(distributions of the dominant factors, bioclimatic needs, needs to each passive design strategy, and the order of priority, etc.) of Seoul are analysed and presented as an example. Also, passive climatic design process making use of this tool is presented.

A ratio of cosine values of two intersection angles in a tractor-rotary power driveline was established as a design criterion which must be satisfied in the range of vertical movement of the rotary with respect to the tractor. In addition tractor-rotary power driveline was analyzed and 25 design variables were Proposed. The intersection angles were also derived using the design variables. Using the design condition and variables, a computer program was developed to evaluate the performance of the driveline and to simulate the vertical movement of rotary. Several methods for searching the optimum design were also suggested.
