The Joongang Ilbo often posts long articles in English which are quite good, and one I just read one titled 'The silent, deadly curse of bullying'. It looks at a 21 year-old woman who was bullied for years in middle and high school, and who is now a councellor for bullied children.
I could dig up lots of other articles about bullying in Korea, but I'm sure anyone familiar with Korea has a pretty good idea of how nasty it can be here. Contributing to this is the fact that, unlike many children who are bullied in the west, who have at least a friend or two, childen in Korea who are bullied are often totally ostracized, as no one wants to be associated with them for the fear that they, too, will be targeted by bullies. Another factor is the institutionalized violence prevalent here, especially in the school system, which lead the victims to simply 'shut up and take it,' and often not even try to fight back.
I'll be delving into this topic more in the near future. The article is here.
