With the help of the advancements in information and communication, information appliances are changing. Flat panels made it possible for information appliances to become smaller in size and lighter in weight, and high end graphics provide increase in realistic and immersive use. Even with these advancements interest in design for laboratory equipment tend to only stay on a level of the exterior of the equipment, not to the point of designing the interface of display GUI. Inspired with the problem above this research would contain the preference analysis ondisplay GUI design considering the characteristics of the main users and the laboratory equipment itself. The test would be held through comparison of graphic-based display GUI and text-based display GUI and analyzing the task time and number of errors made, looking for which display GUI scientist prefer. The test results show that text-based GUI has a higher efficiency but the actual users preferred the graphic-based display GUI.

This program is developed to design Prestressed Concrete Cylinder Pipes (PCCP), Fittings and Thurst Blocks and to manage drawings, quantity calculations and calculation data, using Graphic User Interface(GUI), which is capble of not only reducing the time taken to design, but also enabling the user to achieve such a design even when operator has no theoretical knowledge of that design while only having knowledge of data inputting and outputting. PCCP is used in water transmission popeline of the Great Man-made River Project. In domestic area, PCCP is used for water cooling systems of Uljin and Youngkwang nuclear power. In abroad, especially in the United States and Canada PCCP applies virtually every metropolitan area with raw and treated water.

When an escalator is developed or modified for improved performance, estimation of dynamic characteristics of the escalator is required. But modeling of the escalator for a design purpose is very difficult and time consuming process. Especially, it is very difficult for the designer to use the simulation model during design process because it takes time and also the designer needs to know how to use the simulation program. In order to solve these problems, a graphic user interface program that can predict dynamic characteristics of an escalator is developed for the designer. Since this program has the necessary complicated escalator model inside, the designer does not have to know how to use the simulation program and design parameters can be obtained while design is in progress. The developed designer oriented interface program is explained and an example is shown.

인지모델(Cognitive Model)에 의한 사용성 평가는 실제 실험에 의한 방법에 비해 시간, 노력, 비용을 절감할 수 있다. 여러 인지모델 중 ACT-R(Adaptive Control of Thought Rational)은 인간의 모든 인지과정을 상세하게 묘사할 수 있어 다른 모델보다 정확히 인간의 과제 수행을 정량적으로 예측할 수 있다. 그러나 ACT-R 모델을 수립하기 위해서는 인간의 지각, 주의, 기억 인출 등의 처리 과정과 행동 선택 및 수행에 필요한 과제 수행 규칙을 매우 상세하게 분석 및 기술해야 하기 때문에, GUI(Graphic User Interface) 환경에서 운용되는 메뉴 인터페이스와 같이 다양한 시각적 정보의 처리가 요구되는 과제에 대한 모델을 수립하는데는 많은 시간과 노력이 요구된다. 이에 본 연구에서는 GUI 환경에서 전문가 수준의 과제 수행을 예측할 수 있는 간략화한 ACT-R 모델 수립 방안을 제안하고, 이를 이용하여 상용 통계 분석 소프트웨어의 과제 수행도를 예측하였다. 그 결과 실제 실험을 통한 측정 결과와 간략화한 ACT-R 모델의 예측 결과가 잘 일치하였으며 본 연구에서 제시한 간략화한 ACTR 모델이 메뉴 인터페이스의 사용성 평가에 효율적으로 적용될 수 있음을 확인하였다.

When an escalator is developed or modified to improve its performance, estimation of dynamic characteristics of the escalator is required. But modeling of the escalator for a design purpose is very difficult and time consuming. Especially, it is very difficult for a designer to use the simulation model during design process because preparing a proper model takes time and also the designer needs to know how to use the simulation program. In order to solver these problems, a graphic user interface program that can predict dynamic characteristics of an escalator is developed for the designer. Since this program makes the necessary escalator model for simulation for itself, the designer does not need to know how to use the simulation program while design is in progress. In this paper, a designer oriented interface program is developed and an example is presented to show the effectiveness of the developed program.

It is well known that the quality and efficiency of the design of metal forming processes can be significantly improved with the aid of effective numerical simulations. In the present study, a two-and three-dimensional finite element simulation system, CAMP form, was developed for the analysis of metal forming processes in the PC environment. It is composed of a solver based on the thermo-rigid-viscoplastic approach and graphic user interface (GUI) based pre-and post-processors to be used for the effective description of forming conditions and graphic display of simulation results, respectively. In particular, in the case of CAMPform 2D (two-dimensional), as the solver contains an automatic remeshing module which determines the deformation step when remeshing is required and reconstructs the new mesh system, it is possible to carry out simulations automatically without any user intervention. Also, the forming analysis considers ductile fracture of the workpiece and wear of dies for better usage of the system. In the case of CAMPform 3D, general three-dimensional problems that involve complex die geometries and require remeshing can be analyzed, but full automation of simulations has yet to be achieved. In this paper, the overall structure and computational background of CAMPform will be briefly explained and analysis results of several forming processes will be shown. From the current results, it is construed that CAMPform can be used in providing useful information to assist the design of forming processes.

본 연구는 반도체 검사 장비를 국산화하는 프로젝트의 일환 중에서 메모리 칩의 무결성을 검사하는데 사용되는 메모리 테스트 장비의 소프트웨어 개발에 중점을 둔 것이다. 기존에 발표된 프로그램은 자체 개발된 것 없이 외국의 프로그램을 들여와 단지 운영만을 하는 수준이었다. 더욱이 프로그램들도 text모드 하에서만 구동되는 프로그램이었다. 하지만, 본 연구에서는 새로운 컴퓨팅 환경에서 운영될 수 있도록 윈도우즈 하에서 GUI(Graphic User Interface)에 기반한 새로운 TDL 컴파일러를 개발하였다. 개발된 프로그램은 Test Data를 기술하는데 더 효과적이었으며 오류를 검사하고 수정하는데도 큰 효과를 가져다 주었다.
