50 Summary & Conclusion Materials technology has made remarkable progress through continuous evolution in Korea. Innovation in materials and processing technology makes the bread-earning industries competitive. Translational R/D to bridge the valley of death is strongly emphasized. Group efforts covering all value chains is strongly asked in Government R/D of key materials and components. Coordination of inter- & multi-disciplinary corperation becomes more important in newly converging fields (IT+NT+BT).
