The lecture will deal with the subject of the DMZ and the nearest regions. After explaining what is the DMZ (Demilitarized zone) in terms of a military demarcation line structure, four misunderstandings surrounding the demilitarized zone will be cleared. As an example of the DMZ - Regions relation, the lecture will focus on the case of Cheolwon by dealing with its history, the building of the military villages in the area, the small changes in the villages after 2000, and finally the great Vision of Cheolwon.
