概要	Critical content analysis is a qualitative approach that examines texts, media, and documents not merely for manifest meaning but for how they construct, reinforce, or contest relations of power, ideology, race, gender, and class. Grounded in critical theory traditions, it asks whose interests a text serves, what voices are silenced, and how language and representation naturalise dominant worldviews. It combines systematic analytic rigour with an explicitly emancipatory or transformative research stance.	Semiotic analysis is a qualitative method for interpreting how signs — words, images, sounds, gestures, and objects — produce and communicate meaning within a cultural context. Drawing on the structural linguistics of Ferdinand de Saussure and the triadic sign theory of Charles Sanders Peirce, and popularised as a research tool by Roland Barthes, semiotics moves beyond surface denotation to expose the connotative and ideological meanings embedded in texts and visual culture.
