Soang excavates the idea of equality in our national indigenous thoughts and the theoretical structure of threefold egalitarianism in our traditional Confucianism. He also digests diverse Western thoughts and introduces some of them into his theory. At first sight, his theory looks like an assembly of diverse Western thoughts. However, he always justifies it with our traditions. Even if his theory and political position fails in his time, it gives us valuable instructions. First, if the failure of his political center position means an opening road toward Korean division, his political position must be a future guide for the reunification of Korean peninsula. Second, if the bi-polarization is a serious disease of our society, then his view of egalitarianism must be a efficient guide for curing our society. Third, as European Union shows us, the kingly view of world family is a feasible guide for realizing world peace in future.

The global warming by abuse of fossil fuel is going to become an important problem which must be solved by human beings. This research is to develop a high temperature heat storage tank with high efficiency and to investigate the performance characteristics of this tank to help these energy problem. But the researches for this area have not been enough until now and specially the researches for high temperature heat storage tank are very few. For this research, heat storage bricks were made using MgO powder and studied about the performance characteristics of high temperature heat storage tank by experimental method. Through this research, it was confirmed that MgO can be used as a heat storage material for high temperature range.
