We analyze how linguistic signs (slogans, imperatives) and iconic signs (images, colors) collaborate to transform complex medical data into simple messages accessible to the general public. Drawing on the theories of Roland Barthes, we examine a corpus of 15 posters from international organizations such as the WHO and UNICEF. Our findings confirm that images and text work together to anchor meaning and optimize the preventive impact of the messagefrAwereness postersemiolonguisticsconstruction of meaningRoland barthes.Thesis
