This thesis aim to investigate the experience and practice of chinese history education in secondary middle school of P. R. of China in order to promote the discussion on the social utility and proper form of history and history education which is going on recently in Korea. The history education of P. R. of China has been transformed, reflecting political intention and actual value of state power from 1949. Recently they attempted" to reinterpret and reproclaim chinese nationalism to create new style of national identity to cope with social disintegration after Chinese Social Reformation and more and more deepening globalization. In this context, it is to attempt to imagine process of development of chinese civilization through poly nation-malting status, and in this point understand the World. The attention point is that this project depends on the restoration of traditional system of history understanding and writing style. Of course, they also employ the concept of nationality and internationalism containing socialism, but its purpose is to systematize their own history and understand the world fundamentally. At the same time, they reunderstood the essence of history and tried continually to reconcile the inner object of history with social object of history education, the former based on the originality of history, the latter being national identity and social integration. In this point of view, there is some problems in the chinese history writing, even though it is not absolutely wrong. They take chinese value and culture and their own country"s stand point as something absolute and deny the autonomical development process of neighbor countries. Therefore it is not impossible that they resume the attitude of expansionism as they did in the traditional times.

The purpose of this study was to find out the effect of oxidation by-products for the formation of haloacetic acid (HAA) during ozonation. The phenol was used as a model precursor of HAA, and its oxidation by-products, such as hydroquinone, catechol, glyoxal, glyoxylic acid and oxalic acid were investigated to find out how much HAA formation potential (HAAFP) they have. As the result, among the phenol and its oxidation by-products, the highest reactivity with chlorine was found from the phenol, showing the highest HAAFP. Even though the tested by-products had a lower HAAFP than phenol, it was confirmed that all of them can act as the precursor of HAA. From the ozonation of phenol-containing water, it was found that the efficiency of ozone in controlling of HAAs can be reduced due to the oxidation by-products. In addition, the ozonation of HAAFP was performed under the both pH conditions (acid and base), and the result indicates that OH radical play a important role to decrease HAAFP.
