You contact the right person, Dohyun Kim. He is one of the expert in KTUG and who write kor-00 module for ConTeXt. Another way for Korean is to use XeTeX+ ConTeXt, then you can use some korean fonts in the system. I think that using the module kor-00 is easier.
If there are someone who want to use korean go www.ktug.or.kr and download the font files and module. Just untar the files in the texmf- local directory. It is easy to use.
