Content Analysis of Lexical Cohesive Devices in the Lectures of the Minister of Health, Treatment and Medical Education of the Raisi Government in The Field of Health Care, Treatment and Health

In the current research, the content of the lectures of the Minister of Health, Treatment and Medical Education of the Raisi government in the field of health care, treatment and health were analyzed from the perspective of the use of lexical cohesive devices and in the framework of role oriented of Haliday and Hassan (1976). The research was conducted in a descriptive and analytical way, and the content was three lectures in the field of health care, treatment and health, which were randomly selected. Lexical cohesive devices were extracted in three lectures and their frequency was measured. The percent of occurrence of each device was also obtained. After examining the data, it was found that the first lecture with 261 cases, the third lecture with 254 cases and the second lecture with 246 cases are in the first to third ranks, respectively, in the use of cohesion devices. In the first speech, collocation was the most used cohesive device and hyponymy was the least used device. In the second speech, repetition and hyponymy were respectively the most and the least cohesive devices used in this lecture and in the third lecture, collocation was the most and hyponymy was the least device used. In order to perform a more detailed statistical analysis and find significance in the distribution of cohesive devices in each of the lectures, the chi-square test was used. Based on the results obtained at level (p<0, 0/05) there is a significant difference between the distribution of cohesive devices used in each of the lectures.
