Lots of automation equipments and robots have been developed and been used. But most control systems have been developed as dedicated systems rather than general-purpose systems. Thus, users cannot modify or improve their software including GUI. In this paper, an open architecture GUI is proposed in order to make it easy to modify some functions of GUI or to add some functions of GUI. The format of all menu is similar as in previous systems, but some menu can be deleted and be added. Also some menu can be defined by users.

This paper presents improved GUI based analysis tool o( load flow of power system (or contingency. It is effective tool to facilitate the teaching and learning of load flow of power system. This software is the named of PFGUI(Power Flow GUI) that written in TooIBookII of Asymetrix. The PFGUI is friendly for study for power system operation and control because picture provide a better visualizing of relationships between input parameters and effects than a tabula type result. This PFGUI enables topology and the output data of load flow for line outages to be shown on same picture page. Users can input the system data for power flow on the the picture and can easily see the the result diagram of bus voltage, bus power, line flow. It is also observe the effects of different types of variation of tap, shunt capacitor, loads level, line outages. Proposed PFGUI has been studied on the Ward-Hale 6-Bus system.

This paper presents a Windows graphic developed by the authors for the education and training of power system. Object-oriented programming is a major trend in computer software because it increases flexibility of large-scale software systems. An efficient platform for power system simulation applications has been proposed. This paper presents an intuitive Windows-based program for the power system analysis. The advantages of the object-oriented approach are demonstrated with an implementation of the graphical program. It provides a graphical interface for designing the one-line diagram of the bus and analyzing the output of the simulations. A graphical editor to visually edit the power system, diagram, results processing and exporting and graphic presentations.

Scene Transition Nets(STN) is a very useful modeling method for discrete-continuous hybrid systems. However, it is difficult to write STN in standard object-oriented programming languages because STN programming requires much skill of object-oriented programming and high knowledge of STN of designers. To overcome this problem, the authors have developed a useful GUI simulator software for modeling and simulations of STN. The experimental results of a transport system including an AGV showed the availability of our software.

The study of Web GUI(Graphic User Information) system for Virtual Reality System is mainly performed on effective methodology which transform real world data to computing world data. MGIS(Marine Geographic Information System) has its own target on reliable data service by acquisition of geometric information using accurate measurement and graphical visualization. This type of raw data visualization can be built without software tools, yet is incredibly useful for interpreting and communicating data. Even simple visualizations can aid in the interpretation of complex 3D relationships that are frequently encountered in the geosciences. The Virtual Reality Modeling Language provides an easy way for geoscientists to construct complex visualizations that can be viewed with free software. This study propose a three dimensional Web GUI system using MGIS-based three dimensional data models and virtual imaging system. Finally, we design a Web GUI system integrating above data models.

In this paper, the performance analysis of the vehicle with the Ravigneaux type automatic transmission has been carried out using information of engine and drivetrain. It is necessary to understand the overall system including engine, torque converter, clutch, planetary gears, and road load. The equations of motion are derived from dynamic model. The GUI computer simulation program has been developed to analyze the powertrain performance of the vehicle with the Ravigneaux type automatic transmission.

Bellows product is an important part in the area of plant engineering, shipbuilding and petrochemistry. For safety and durability it is necessary to consider lots of factors when designing it. This research developed a U-shaped metal bellows design software based on EJMA 9th Edition manual. This GUI software was developed by using Matlab software and can be able to design four types of bellows, Unreinforced Single Bellows, Unreinforced Double Bellows, Reinforced Single Bellows and Reinforced Double Bellows. The already proven bellows model was designed to verify this software. We investigated the behavior while changing the thickness of the bellows. As the thickness of bellows increases, spring rate, thrust force, stress increase and fatigue life decreases. This software will be helpful design engineers save time and effort.

High temperature vacuum furnaces or high standard electric furnaces demand high technology level and high production cost. Therefore, an iterative design process and the optimization approach under integrated computing environment are required to reduce the development risk. Moreover, it also required to develop an integrated design software that can manage the centralized database system between factory and design department, and the automated furnace design and analysis. The developed software is dedicated to the development of the vacuum (electric) furnaces. Based on the distribute middleware system, the GUI module, the CAD module, the thermal analysis module and the optimization module are integrated. For the DBMS, Microsoft Access is employed, the GUI is developed using Visual Basic language, and AutoCAD is utilized for the configuration design. By investigating the analysis code interface, the analysis and optimization process, and the data communication method, the overall system architecture, the method to integrate the optimizer and ana lysis codes, and the method to manage the data flow are proposed and verified through the optimal furnace design.

오늘날 SW는 끊임없이 새롭게 개발, 업그레이드되고 있다. 이러한 상황 하에서 단순히 많이 사용되는 소프트웨어를 선별하여 그 기능을 가르치는 방안은 근본적으로 한계를 가지고 있을 수밖에 없다. 배우고 가르쳐야할 SW와 학습량은 계속 늘어날 수밖에 없기 때문이다. 따라서 기존의 보고 따라하는 식의 전통적인 학습 방법에 의존하기보다는 응용SW의 특성에 기초한 새로운 학습 방법을 강구할 필요성이 제기되고 있다. 최근 생산되고 있는 대부분의 SW들은 거의 모두 GUI환경으로 구성되어 있다. 따라서 학생들이 범하는 여러 가지 오류 중에서 GUI환경과 연관되는 것을 찾아 이를 처리해 준다면 대부분의 소프트웨어 학습에서 많은 오류들을 줄일 수 있을 것이다. 이에 본 연구는 GUI 에서 일어나는 여러 가지 오류들에 대해 알아보려고 한다.
