Is the purpose of this board the exercise for good command of english? Or, being accustomed to American or Western culture? Well, I don't have any information of this board, just I do have a curiosity. Oh, I'm sorry. Let me introduce myself. My ID is BONG which was quoted in the last letter of my name. And many a friend call me 'BONG' when we talk orally. This is POSTECH, and my major is chemistry. If you would inform me of this board, I could participate in this board more comfortablly. Thank you.
