본 연구는 하천 호안의 안정성에 대한 값들을 체계적으로 정리하고 관련 기법을 컴퓨터 프로그램으로 개발하여 실무자들이 호안의 시공 설계시 안정성에 대한 평가를 쉽게 할 수 있도록 개발된 프로그램이다. 프로그램의 사용을 쉽게 하기 위해 GUI(Graphical User Interface)의 기능이 뛰어난 Visual Basic을 사용하였으며, Data-Base를 기반으로 하는 Menu-Driven 방식을 채택하였다. 프로그램의 기본구성은 호안의 수리적 안정성연구를 바탕으로 국내의 하천에서 가장 많이 사용되고 있는 식생호안공, 돌망태공, 식생호안 블록공의 3가지로 구성 되어 있으며 각 호안공의 소류력에 필요한 수리 특성 자료와 각종 계수, 호안에서 측정되어진 값을 산정 후 각 호안의 내력 소류력 값과 외력 소류력 값을 산출 한 뒤 이 들 값을 비교하여 호안의 안정성을 평가하였다. 호안의 안정성평가 프로그램을 바탕으로 하천호안의 축조 및 최근의 생태성이 강조된 하천의 호안 시공 설계 시 많은 사용이 기대된다.

Interactive Measuring part Program Generating Tools (IMPPGT) realized on the FANUC 15MA using touch trigger probes and interactive macro functions os the CNC were developed for an intelligent measuring and inspection systems on the machine tools. Menu driven measuring and inspection functions of the IMPPGT were studied and implemented on the CNC through the macro executer and ROM writer. In order to automate measurement and inspection procedures in machine shops measuring G Code system was also proposed. Using the developed measuring G Code system on the machine tool untended measurement and inspection operation was able to be realized in FMS lines.

A menu-driven shell program DSFS (Daily Streamflow Simulation Model), that can process the input data, optimize the parameters, execute the program, and graphically display the results of a modified tank model, was developed and applied to simulating daily streamflow from small watersheds. The model defines daily watershed evapotranspiration losses from potential values multiplied by monthly landuse coefficients and correction factors for soil water storage levels. The parameters were calibrated using observed hydrologic data for fifteen watersheds, and the results were correlated with watershed parameters to define empirical relationships. The proposed model was tested with streamflow data of ungaged conditions, and the simulation results overestimated the annual runoff.

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.

The purpose of this study is to develop a computer program for automatic dart manipulation, as well as basic pattern making, of women's front bodice. In addition to accuracy and efficiency In pattern making, this computer program provides variations of basic patterns through dart manipulation. AutoCAD, running on the Austin 486DX micro-computer is used for this research. The procedures of this study are as follows : 1. A pattern-making method for women's front bodice is selected. 2. All co-ordinate points are located following the same way and order of drafting. 3. Drafting of a basic front bodice is programmed 4. Functions for various single dart manipulations are defined. 5. Menu-driven user interface is developed.

For improvement in productivity and weld quality, weld seam tracking and welding parameter control are very essential in the welding of a structure which can not be cxactly fit-up due to mismatch, discontinous gap, deflection, etc.. In this study, an automatic weld seam tracking system is developed for I-butt joint structure, and the system consists of XYZ working table, vision sensor and user interface program. In the developed vision sensor system, an image projection algorithm for weld-line detection and an adaptive current control algorithm for gap variation were implemented. The user interface program developed in this study by basing on the objct oriented concept could provide very convenient way to utilize the tracking system with the pull-down menu driven structure. The developed system showed a good seam tracking and weld quality control capability corresponding to deflected weld lines and gap variations.
