原子力開発・利用をめぐるメディア議題 : 朝日新聞社説の分析(上)  [in Japanese] A Media Agenda Regarding the Development and Use of Nuclear Energy: The Analysis of the Editorial of the Asahi Shimbun(1)  [in Japanese]

This thesis is a part of research to verify what kind of"media agenda"the Asahi Shimbun newspaper has shown concerning the development and use of nuclear energy in Japan. The target of the analysis was the editorial of the Asahi Shimbun from the days after the war until the end 1970. First, the agenda regarding the development and use of nuclear energy was classified into four categories, and then under each category, the change of value judgments of the Asahi was tracked and put in chronological order. As a result, it became clear that the media agenda of the Asahi had been based on the premise of promoting the use of nuclear energy up until the end of 1970. Especially during the period from the first days of nuclear power plants until the start of its commercial use, almost no critical agenda can be found in the Asahi. And until specific accidents and troubles occurred, the safety of nuclear power plants had been regarded as an"established"matter.
