What is your topic for portfolio?

When Dr Yeon asked us to submit a portfolia by the end of May, I felt very burdened. At first I though it could be a very helpful teaching material. But as time goes by, to search for some materials is not easy and sometimes put away because of the tasks or homework from the core courses. Anyway I tried to find an easy way to do the portfoli0. I did it. My potfolio topic is food.
But this one is mainly focused on the food in Asian which reflects the current situation of increasing multicultural families in Korea.
