This study was approached from the perspective of a historical trauma. This study was analyzed from the perspective of the 2nd generation of Jeju 4.3 experienced residents, unrelated to the ideology of right or left. In order to confirm the evidences of this historical trauma, the Korean national daily newspapers titled DongaIlbo(1962-1999), Kyung Hyang Newspaper (1947-1999), Maeil Business Newspaper (1966-1999), Hankyoreh Newspaper (1989-1999) were analyzed by the key word of Jeju 4.3(제주 4.3) and 제주사태(Jeju incident) in the Naver news library. This research showed that the sense of safety or security at the level of exo system including media as well as at the macro system including ideology was never secured for Jeju people related to Jeju 4.3 over 70 years. If this sense of safety or security at both macro and exo system is not secured, individual memory and mourning at micro system level cannot approached. Therefore publicly guaranteed safety feeling at macro system level including policy and media should become the starting line to recover the Jeju 4.3 historical trauma. The historical trauma related to Jeju 4.3, which has been handed down through generations in the silence of 70 years, should be solved by the central government policy in terms of the macro, exo, mezzo, and micro systems.
