6·15 joint declaration is an official document both of South and North have agreed to for a peaceful reunification of race. What is more, it is the first document both summits of South and North have agreed to. There is, however, considerable difference between two nations in the degree of importance each Korea gives the document. It shows openly the difference of ideology and system between two Koreas. In North, the importance of the document is unquestionable for the will of North Korean leader Kim Jong-il, an absolute authoritarian ruler, is contained in the document. On the other hand in the democratic system of South, the importance of the document has diluted by the opposed political power for the will of Kim Dae-jung, the president for a certain period of time, is contained in the document. North Korea takes the first clause of 6·15 joint declaration document as a priority and emphasizes racial cooperation and ‘just between ourselves’. It is an internationally justified agreement that reunification should be made on our own will and for ourselves. However, South’s passive reaction to that has rather provided North with an excuse of criticism. It was a period of 6.15 when the solution process in political problems was reaffirmed to be still rough and difficult. On the other hand, visible achievements have been made in the aspect of economical cooperation and humanitarian solution of matter, which can be said to make a historically remarkable process.

Objectives: This study was conducted to evaluate the antioxidative and anticancer activity of the water and ethanol extracts from pickled soybean products by manufacturing stage. Methods: Yakkong (YK) was pickled for 15 days to prepare Chokong (CK) and Chokong pills (CKP) were mixed Chokong (CK) powder with vinegar. Herbal Chokong pills (HCKP) were made by addition five kinds of medicinal herbs to Chokong. Pickled soybean products by each manufacturing process were extracted with distilled water and 70% ethanol, and the extracts were tested for their antioxidative and anticancer activities. Results: The highest electron donating abilities (EDA) of the water and ethanol extracts were from HCKP among pickled soybean products and those were 81.2% and 91.5% at 1,000 μg/mL, respectively. The ethanol extracts of pickled soybean products had higher activities of EDA and superoxide dismutase (SOD) than water extracts. The highest anticancer activity was the water extracts of HCKP against both of MDA and A549 cells. Conclusions: These results suggest that herbal Chokong pills (HCKP) can be used as natural antioxidant to prevent oxidative damage in normal cells probably because of their antioxidative characteristics.
