概要	Critical semiotic analysis is a qualitative method that examines how signs — words, images, gestures, sounds — construct and naturalise ideological meanings. Drawing on Roland Barthes's distinction between denotation and connotation, and on critical social semiotics developed by Kress and van Leeuwen, the approach moves beyond surface-level description to expose how texts reproduce or challenge power relations, cultural norms, and dominant ideologies.	Visual analysis is a qualitative research approach that systematically examines visual materials — such as photographs, films, artworks, advertisements, and diagrams — to understand how meaning is produced, communicated, and interpreted. Drawing on traditions from art history, semiotics, and social science, it treats visual objects as data that carry social, cultural, and ideological significance. Multiple frameworks exist, from formal compositional analysis to discourse-based and audience-reception approaches.
