A field-sequential color projection system can display color images using panel. However, it suffers from a characteristic trichromatic separation known as "color breakup". The viewing of images exhibiting color breakup may cause visual fatigue and mental stress. In this study, the authors examine, from the standpoint of human factors, the objective and subjective symptoms that can result from the viewing of images with color breakup.

This research analyzes the level of technological growth in Korean telecommunication industry and suggests a technology development strategy. Comparative analysis of technological growth with the advanced countries was performed based on a new technology classification scheme. Technology indices were calculated by applying Analytical Hierarchy Process(AHP). The result of the AHP was put into forecasting models to have a glimse of future growth pattern and to suggest a long-term development strategy for telecommunication technology.

In 2006, ITU-R estimated the spectrum requirements for IMT-Advanced including IMT-2000 and its enhancements. And WRC-07 indentified four new spectrum bands for IMT system. Based on these results, there are many activities which are related with IMT system and its spectrum inside and outside of the country. This paper covers the next generation mobile telecommunication spectrum issues and outlook for the future of it.
