One more picture of Yunjin in the September 2011 issue of Vogue Korea popped up on the magazine website:
The page linked above features an interview, too. I don't understand Korean so I can't offer a translation, sorry. (Google is good enough to "decode" captions and blurbs, but isn't of much help in cases like this - so I'll take the opportunity to say that if any reader speaks the language and would be generous enough to submit a translation or quick summary in English, or volunteer to help out with the blog and other translations in the future, I'd be very very grateful. :) )
Also, here is a photo of the third image published inside the magazine, posted by wj9513262 (click to see full size):
