Designing a model to measure the performance of Persian language satellite and television networks in the lifestyle after the Corona crisis

Aim and Background: Our country is one of the most vulnerable countries in terms of suffering natural disasters in such a way that during the 20th century, the statistics of human and material losses resulting from incidents have placed Iran among the top ten countries in the world in terms of disaster and vulnerability; on the other hand, considering the role of the media in the representation era or the age of media in shaping our understanding and imagination of disasters in today's world, one of the important dimensions of disasters is to know how visual, audio and virtual media work during a disaster. Therefore, without knowing the performance of the mass media, we cannot practically know many aspects of the disasters and society's response to it at the national and international level. The media not only informs, encourages and persuades the society to provide relief and mobilize facilities when a disaster occurs but also they are very effective in the renewal and revival of the society and the changes that occur in the beliefs, behaviors and lifestyles of the members of the society before, during and after it. Method: In this research, it has been tried to determine the prioritization and effect of Persian language satellite and television networks on the lifestyle after the Corona crisis with a mathematical model of rough data envelopment analysis. This research is an applied study and its method is case-based and in order to measure the before mentioned Channels, field and library studies were conducted on the variables and indicators of lifestyle after Corona, at first; and after reviewing the articles, in order to calculate the research indicators, a guided interview was conducted with experts in this field who had at least 10 years of experience in the fields of lifestyle, media and culture. Findings: The findings of this research indicate that MANOTO Channel has had the greatest impact on the people's lifestyles after the Corona disaster and after that the NASIM and GEM channel are in the second and third places. Results: According to the ranking of the channels, it is important that the lack of actions of the domestic channels, such as lack of quick, accurate and clear information and concealment of facts and statistics, gives the opportunity to the satellite channels and reduces their social capitals; on the other hand, in the case of producing high-quality programs that suit the audience's taste, such as entertainment and family programs in NASIM channel provides the possibility of competition and influence for domestic channels.
