The Korean translated pages of the originals in 'Category:Countries', which are generally '/lang-ko' subpages. These are NOT Korea-specific but only 'translated' in Korean language.
The only exception is the 'OLPC Korea' page because it is the 'country page' of Korea in this wiki which contains the status of OLPC in Korea. Though it is mainly written in Korean, it is not a translated one. Therefore it should be included in Category:Countries instead here. Other Korean-specific pages are perhaps located in 'OLPC Korea' subcategory.
