This poper proposes a manpower cultivation index(MCI) which can be used for evaluating how much a research project contributes for manpower cultivation. The four factors which are considered to influence the manpower cultivation are the number of participated graduate students(research assistants) , the number of graduate students who obtain master or Ph. D. degrees among the participated graduate students in the research project, the number of research papers published by participated graduate students, and the number of graduate students who get jobs. By the proposed MCI, three major research projects of KOSEF are analysed in terms of manpower cultivation. These are SRC/ERC(Science research center/Engineering research center) and RRC(Regional research center) and OBR(Objective based research) . The computed MCls show that the three major research projects enjoy satisfactory manpower cultivation to some extent.
