장기주,신인수 韓社大學 産業福祉硏究所 1978 産業福祉 Vol.2 No.-
<Ⅰ> Economists have long been aware of the importance of educational investment. J.A.Schumpeter, for example, stressed the necessity of the leading labour and spirits of enterprise and added that it could be accomplished through more education and training. <Ⅱ> Generally, the investment in education brings in income increase, because there exist the rates of return to educational investment. And G. S. Becker worked positively with the studies about it. But there is in the world today a correlation between the education level and economic level in the various countries. <Ⅲ> The consensus among economists today is that advance in education leads to economic progress. In other words, educational investment as investment in the human resources is a prerequisite for economic growth. A strategic part of the present post training, scientfic and engeering education, reorganization of a cause structure to specific high human power are directly in accordance with an economic objects. For the future demand of human resources, a planner of human resources should put an emphasis on making an exact object than just prediction. And the demand of human resources must be a general one. Mainly, expenditures on education come from local and central government budgets. But the finance support methods as well as sum total are essential. Gradually, the major part of development plans call for the increase expenditures on educational investment.

Atomic Structure of B-P and Self-Interstitial-B-P Complexes in Si
장기주,Chang-Youn Moon,Yong-Sung Kim 한국물리학회 2003 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.42 No.III
We investigate the atomic structure of B-P pairs in bulk Si through first-principles pseudopotential calculations, and find that a B-P pair is energetically most stable when P is positioned at a substitutional site in the second nearest neighborhood of B. We also examine the energetics of various I$_s$-B-P complexes that consist of B, P, and Si self-interstitial (I$_s$). In this complex, P also prefers a substitutional site in the second nearest neighborhood of B; however, its actual position depends on the charge state of the complex. We find that the formation of the I$_s$-B-P complex is energetically more favorable than for the I$_s$-B complex, which is a major diffusing species in B-doped material.
