Semiotic Investigation of Visual Components of World Health Organization Educational Posters (Case Study: Coronavirus 2020-2021)

The semiotic analysis of the poster is a set of visual-textual signs based on the inter-signal relationships. The interdisciplinary nature of the subject of this research (linguistics, psychology and graphics with semiotics) makes the analysis of educational posters and semiotics inevitable. In designing a poster, all the codes of the artist are decoded by the audience, and the artist must be aware of how to decode the audience. This research was conducted with the aim of knowing the goals of semiotics and how the World Health Organization uses visual signs for the audience in educational posters of medical diseases. The questions are as follows: What effect does universality have on the selection of visual signs of the desired posters? How has the World Health Organization benefited from semiotics in educational posters? The research method was descriptive-analytical and library research and documents study based on the three groups of educational posters of the organization, three samples of the posters were examined. It research findings indicated that in UN educational designs, the use of appropriate designers using semiotic results tools derived from the opinions of "Ferdinand de Saussure" and "Charles Sanders-Pierce" helped the audience to understand more complex signs and made them read educational messages. Universality is properly displayed in the design of educational posters. Using images for people with different educational levels, showing different races with different costumes and beliefs, showing genders at different ages are other factors that the organization should have knowledge of.
