신상품 개발을 위한 트랜드 이미지의 수집과 분석(타운워칭, 캐털로그 분석 등)은 이미 디자인 전개과정에 깊숙히 자리잡고 있는 기법이다. 그러나 대부분의 경우 트랜드 이미지의 수집은 디자이너의 직관에 의존하는 경우가 많았기 때문에 실질적인 시장상황을 반영한다고 하기에는 다소 힘들었던 것이 사실이다. (중략)

The use of network planning models and tools is essential for effective KII (Korea Information Infrastructure) planning and analysis in that it will significantly reduce the risk and uncertainty embeded in the development and the provision of future broadband services. The purpose of this study is to develop a theoretical framework and a computer tool for modeling the various aspects of the KII topology and architecture and evaluating the techno-economic feasibility of the KII implementation strategy.

GIS(Geographic Information System) tool has been applied to determine a spatial difference of weed population density in paddy field and it has introduced to rice yield difference among counties as well as to rice blast in Korea. There was highly difference between sampling sites in terms of spatial analysis which may imply to be able to apply this tool for the precesion agriculture in the 21 century.

This study provides a thorough methodology for IT Investment evaluation. A software tool to support the evaluation process was introduced along with a case study. The software supports the methodology that consists of 7 phases : Target analysis, ldentifying IT measures, Measuring IT impact, Assessing business value, Analyzing the decree of realization, Cost-benefit analysis, and Reporting. The case study showed that the software (CAFA) was a very useful tool supporting both decision-making and post-implementation reviews of IT investment.

A CAM program for forming design Automated of CAM for Spring using car was developed in this study. This program was written in AUTO LISP on the AUTO CAD system with a personal. An approach to the system is based on the kinemateic of the object function. We make a determination of an cam programming. A CAM spline is continuous in displacement. velocity and acceleration. This program which can design Coil Spring shapes will successfully support CAN designing and manufacturing for Small & Medium companies.

This paper introduces the system AUTO-CUT for the automatic generation of NC tapes for wire-cut EDM (Electrodischarge Machining) parts. The information input to the system is the description of the part geometries, the tool motions and the cutting conditions etc. The system generates CLDATA. Also dynamic graphic display of the tool motions can be-performed on the screen.
