  • Springs for vehicle suspension control the vibration of a car and influence on the ridability, safety, and life of a car. In the paper, the computer aided design program has been developed, which design the leaf spring shape from the given specifications using basic theory and the expert's knowledge, and the design results are checked by the analysis theory in order to increase the accuracy, and feed back to the design input. For the purpose of easy use, this program consists of pull-down menu and interactive input mode. To prove the effectiveness of this program. two springs, of which one is symmetric, other asymmetric, are designed and analyzed, and the outputs are compared to the experiments. Considering the tolerance of the given specifications, the results are good.

  • A computer program for personal computers, $K-BEtest^{\circledR}$, was developed to analyze bioequivalence data in accordance with Korean Guidelines for Bioequivalence Test (KGBT). This program is user-friendly, interactive, Hangul-compatible and supports $2{\times}2$ cross-over design as well as $2{\times}2$ Latin square design with various significance levels. This program is able to calculate AUC, $C_{max}$ and $T_{max}$ parameters from the blood drug concentration-time profile of individual subjects and evaluate the parameters statistically for the bioequivalence by ${\pm}20%$ rule, the F-test, the Non-centrality test and 90% confidence intervals. All procedures are supported with graphic interface, interactive menu and outputs in Korean. In this paper, two experimental data sets were analyzed by the program and detailed process was demonstrated. The $K-BEtest^{\circledR}$ program appears to be very effective for analyzing bioequivalence data and can be widely used with convenience and accuracy.

  • This paper is concerned on kinematic analysis and simulation of an automatic feeding mechanism subjected by the motion of a curvilinear inverse cam. The main objection is the development of computer-aided design (CAD) program for simulating the motion of the cam-feeding mechanism using computer-graphics. A computer program CACAFS (Computer-Aided Cam and Automatic Feeding System) is independent of computer hardware used. The program is also interactive using a menu-selection technique. As the second part of the paper for the motion simulation of the cam-feeding system, this paper discusses the state-of-art for CAD. The first part of the paper presents the algorithm to simulate the notion of the cam-feeding mechanism.

  • A PSWATH is a computer program for the determination of principal particulars of Small Waterplane Area Twin Hull (SWATH) Ship design at the preliminary design stage. This paper describes the PSWATH system and the underlying theory. The major calculation modules are hull definition, resistance and propulsion, weight estimation and pitch stability analysis. Use of the model is illustrated by input, output and means of examples.

  • In this study, computer program for the optimum design of two continuous box culvert was developed. It was shown that even though the starting points and optimization method are different, the objective function and optimum design variables converge to a value within a close range respectively, and consequently the optimum design program developed in this study is reliable and robust. MMFD is the most efficient one from the viewpoint of convergency and computing time.

  • We are in the process of developing information systems that can be helpful for the effective management of community health services provided by the health center and subcenters in Hwachon Gun, Kangwon Do. In doing so, we have employed a different program design from those programs of information systems developed in other health centers or subcenters. The main idea of our design is dividing all the programs into two parts. One part is for the control of operation functions such as addding, seeking, editing, and printing needed to all the tasks. The other consists of a set of programs each of which deals with a specific task. It is believed that this program design would result in an information system that is simple to use, easy to modify and expand, and flexible to new computer technologies.

  • In this paper a free-form hull design program and performance prediction program for planing boat is introduced. This program enables the designer to do complex geometric hull shape design on a personal computer and accurately to predict power requirements for a given loading and velocity. For a free form design, Bezier curve model is adopted as a basic representation tool of curves and surfaces, and this program has versatile functions to do fairing jobs with a convenient graphical user interface. After creating a hull form the geometric data is provided in a manner compatible with a variety of analysis tools including 'Motion Analysis(by Zarnick)' for prediction of motion characteristics in regular waves, 'Running Attitude (by Savitsky)' for prediction of the running attitude and required power.
