Recently, with a progressive development of hardware of computer, the internet and network technology, the environment of construction varies rapidly due to increase the complex form in structure shape and system. With variations, the CAD system for design and products also varies from 2D system to 3D system. This study mainly deals with the methodology of automatic connection design of 3D CAD system, steel connection system (XSteel) using macro. First, using design program in the steel connection system, Xsteel, the joint connection macro will be made up and established the detail classes of design. The next, Database Program (Converter Program) related to the general structural analysis program (MIDAS) and the steel connection program (Xsteel) is constructed for data interface between two programs. From this study, if the merits of 3D CAD system and converter program are utilized well, it is expected that the time needed in modeling and the amounts due to material loses decrease gradually.

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.

Recently Development of construction system that subjective operators share and control information efficiently based on the three-dimensional space and design information throughout life cycle of construction project is progressing dynamically. In case of civil structures which are infrastructure, Demand for structure of complex system which has multi-functions such as super and smart bridges and express rails is increasing and system development which computerizes and integrates process of structure design is in need. For that, research about link way between three dimensional modeling data and structure analysis programs should be preceded. In this research, therefore, research about interface design between three dimensional virtual modeling data to automate efficient civil-structure-design and nonlinear finite element analysis program which is made up of reinforced concrete material model that express material's character clearly.

The paper presets the improvements of MMI at the PROSET2000 correction program which is totally computerized system of the power system protection. The Base Form that is an open interface is developed to be able to compose the screen by reading the input screen from the database. It also is developed to be suitable for the environment of the Graphical User Interface instead of the DOS window when the users do the pannel settings. Program development in this paper is designed by Unified Modeling Language(UML) techniques.

SDAI (Standard Data Access Interface) is an interface specification of accessing various storage systems such as file systems and database management systems for STEP data. Using SDAI, both application program developers and CAD/CAM system developers can be relieved from dealing with STEP physical file or system dependent DBMS operations. In this paper, we present implementations of SDAI on different data models, i.e., relational, extended relational, and object-oriented. In order to implement SDAI, we need to translate the EXPRESS information model into target data models. The schema translation process for three different data models are compared and other implementation issues are discussed.

A graphic user interface program for the design of vehicle suspension system is developed in this work. Graphic templates are designed by using a graphic language and a library and given to users for interactive data input. Several suspension types are graphically given, and the information of hard points can be directly provided on the graphic templates by users. The information is saved in a data structure which can be efficiently accessed, and transformed into another data format. The data transformation is for the interface to an analyzer by which suspension design characteristics can be calculated.

In this paper, we developed digital TV interactive game using mobile device. This enables a TV viewer to participate in the game using mobile devices. Recently, advanced interface is adopted in the mobile devices, especially touchpad type interface is favorable. Such type interface has the advantage of more familiar interface for users, and the user can input various type of action. Using a mobile phone enables many users can participate in the TV game, and provides a private screen. In this paper, we describe contributions of the program in detail, and we present the architecture and a demonstration of the proposed program in a similar broadcasting environment.

Recently, due to the advanced computer technology, momental architectures have been designed and built using features that are very sophisticated. People's interest in free-form structural system has increased steadily not only nationwide, but also worldwide. However, there were many difficulties in the materialization of free-form structural system owing to the lack of technique and research. To solve this problem, this study performs the interface between the 3D modeling program and the optimization program. In the 3D modeling program, it is possible to automatic mesh generation and immediately to information extraction. It performs the shape optimization. Consequently, this research designs the example model and performs optimization in order to verify the developed interface module.

Although people want to learn guitar easily and happily, it is difficult to learn because many restriction comes from expense, student's efficiency and teacher/s skill. In this paper, the guitar teaching program has been developed for who is difficult to learn guitar fingering. The guitar teaching system with ATmega 128 was programed using visual studio MFC program. The guitar fingering U/I program was investigated for beginners easy to learn the code and playing with guitar.
