The development of computer-integrated design systems that fully support structural design process needs the computerization of structural design at the preliminary design stage. The objective of this paper is to develop a prototype system for preliminary design of reinforced concrete structures. This study focuses on the development of a natural design process oriented GUI(Graphic User Interface) and a representation of an experienced knowledge. The prototype system has been currently implemented using the objected-oriented programming concepts, the program language(i.e.,Visual C++) and the expert shell(i.e., Intelligent Rules Element).

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.

The current industrial development and the Increase of population along Nakdong River have produced a rapid Increase of wastewater discharge. This has resulted in problem of water quality control and management. Although many efforts have been carried out, water quality has not significantly improved. The goal of this study is to design a NGIS-based water quality management system for the scientific water quality control and management in the Nakdong River. For general water quality analysis, QULA2E model was applied to the Nakdong River. A sensitivity analysis was made to determine significant parameters and an optimization was made to estimate optimal values. The calibration and verification were performed by using observed water quality data for Nakdong River. A water qualify management system for Nakdong River was made by connecting the QUAL2E model to ArcView. It allows a Windows-based Graphic User Interface(GUI) to implement all operation with regard to water quality analysis. The modeling system in this study will be an efficient NGIS for planning of water quality management.

Efficient representation is crucial in the analysis of complex geospatial information. In case of aerial triangulation, most of currently available software are designed as black boxes where only an experienced user would be able to prepares the preformatted input file and interprete the result of the adjustment. This paper introduces a solution to this problem through the UML design of a Graphical User Interface (GUI) for the aerial triangulation task. The design was then implemented with ArcGIS. The error of the exterior orientation of each aerial Imagery was represented with a 3-D error ellipse, enabling the visualization of the adjustment result. The attributes of images and points (control points, tie points and image points) were maintained as a database which enables the searching and querying of adjustment information.

As the cconvenience economy of food culture becomes more widespread and the consumption trends for easy and convenient meals grew, every food company is making their various efforts to provide better service. Along with this change, various methods have been allowed for quick and easy ordering. Especially, the introduction of kiosk systems with various merits such as reduction of queues for cashes, saving labor costs, and smoothness of business processes have been actively growing recently. If kiosk system provides not only order but also systematic contents and interface design considering differentiated identity from other companies, brand image enhancement and customer service strategy would be available as well. A kiosk GUI design for effective interactions that provides more usability and satisfaction to users by analyzing the structure and contents of kiosks in fast food stores and GUI designs and investigating usage patterns and design preferences of kiosks through user surveys.

Analysis technology is widely accepted and quite popular these days. Incorporation of the analysis result into design process is a key factor for the success of the analysis area. A few design software products have been commercialized. Generally, they are trying to make an interface between various design methods and analysis software. Optimization is a representative design method. The products are investigated and compared for the aspects of user convenience and algorithm performance. A few popular products are selected. Graphic user interface (GUI) is compared for the function and efficiency. The performances of the optimization algorithms are tested by mathematical and engineering examples. The results are discussed.

In this paper, optimum design problem of R.C. continuous beam is considered and GUI system is developed for using at the practical design. Objective function lot formulation of optimum design problem is made up of the costs of concrete, reinforcing steel and formwork. Design variables are width, effective depth of the beam and steel ratio and design constraints are considered on the strength, serviceability, durability and geometrical conditions. The optimum design problem is solved by using sequential linear programming(SLP), sequential convex programming(SCP) and compared their effectiveness. Also this paper shows the application at practical design work according to the development of GUI system using visual basic.

Because worldwide interest in the health is increased, the real-time health monitoring system has been demanded to be more convenient non-contact and precise medical devices than conventional. Therefore we developed the blood pressure monitoring system using UWB(Ultra Wide Band) radio wave which contact to the human body through the radar and continuously collect a movement signal of the blood vessel. Then the collected data including pulse rate, systolic blood pressure, diastolic blood pressure is processed in real time. The system monitors and controls through a program-based embedded LCD(Liquid Crystal Display) using Qt GUI(Graphic User Interface) to be displayed in real time. We implement the system as a embedded system because of reducing the size of the limited resources. Existing PC GUI design mode is used relatively large memory, therefore it requires more CPU(Central Processing Unit) capacity and processing time.

Nowadays, the development of microfluidic chip [i.e. biochip, micro-total analysis system ($\mu$-TAS) and LOC (lab-on-a-chip)] becomes more active, and the microchannels to deliver fluid by pressure or electroosmotic forces tend to be more complex like electronic circuits or networks. For a simple network of channels, we may calculate the pressure and the flow rate easily by using suitable formula. However, for complex network it is not handy to obtain such information with that simple way. For this reason, Graphic User Interface (GUI) program which can rapidly give required information should be necessary for microchip designers. In this paper, we present a GUI program developed in our laboratory and the simple theoretical formula used in the program. We applied our program to simple case and could get results compared well with other numerical results. Further, we applied our program to several complex cases and obtained reasonable results.

This paper describes the development of the interactive hullform transformation program. This program has many hull transformation functions such as main particular transformation, deadrise generation, section characteristic transformation, local transformation and CB, LCB variation, etc. MBASTRANS adopted the GUI(Graphical User Interface) using the OSF/Motif based on the X-Window system and used X-PLOT and GLBAX which are 2 and 3 dimensional graphic libraries, respectively. The interface module cans generate the information of the hullform for the SIKOB package and the hydrodynamic analysis.
