A soy protein hydrolysate was found to inhibit rat platelet aggregation induced by ADP, an aggregating agent. To find out its principal antiplatelet peptide(s), the soy protein hydrolysate was separated successively by gel filtration chromatography, revere-phase HPLC, and cation exchange HPLC. During the course of separation, we observed that most fractions had antiplatelet effects, which suggests that most peptides have some degree of antiplatelet effect. Following the inhibitory fractions, we purified and identified two new peptides, SSGE and DEE, by LC-electrospray ionization MS and peptide equencing. Both peptides were highly hydrophilic. The concentrations to obtain 50% inhibition ($IC_50$) of the aggregation intensity were approximately $\458muM$ and $\485muM$, respectively, for SSGE and DEE.

The purpose of this study is to provide basic source of learning strategy education to help women married immigrants improve their language skills. To find out women married immigrants` Korean learning strategy features, learners variations(mother tongue, job, age, learning experience of foreign language) and the patterns of Korean learning strategy were analyzed. After analyzing women married immigrants` patterns of learning strategy by using Oxford`s Strategy Inventory for Language Learning(SILL), it is turned out that while there is positive interrelation in mother tongues and jobs, there is negative interrelation in learning experience of foreign languages and there is no meaningful interrelation in ages. In mother tongues, Vietnamese learners use learning strategy more than Chinese learners. In jobs or jobless, learners with jobs use memory strategy, cognitive strategy, meta-cognitive strategy very much. Therefore, there is meaningful difference between women married immigrants` mother tongues and jobs, so when they learn Korean, there should be a differentiation teaching and learning method. First, while Vietnamese learners should have a teaching method of emotion strategy, Chinese learners should have memory strategy, reward strategy, emotion strategy, social strategy. Second, jobless learners should achieve teaching and learning so that they use memory strategy, cognitive strategy, meta-cognitive strategy. (Dongguk University).
