The Korea Herald reported on November 24, 2015 that around 200 professors from 50 universities will be charged with plagiarism. It seems that they published books that they didn't write with just the cover pages changed to include their own names. As most have admitted to the deed (which would be hard to deny, as the original books are published and thus available for comparison), they will soon be charged and fined, which may result in some losing their jobs.
It seems the "academic" publishers were in on the scheme, and even the original authors kept quiet as they did not want to sour their relationships to publishers, as they need publications for their own continued employment. The Korea Observer notes that publishers have even used the tactic to reduce stocks of unsold books, as students will tend to purchase a book "written" by their professor.
The Melville House Publishing company blog lists a number of other academic misconduct issues currently plaguing South Korea.
