概要	Semiotics in Film Studies is a systematic method for analyzing how film produces meaning through signs, codes, and symbolic systems. Developed from linguistic semiotics and adapted to cinema by scholars like Roland Barthes, Christian Metz, and Umberto Eco, it examines how visual, auditory, and narrative elements function as signs—consisting of signifier (the form taken by the sign) and signified (the concept it represents)—to create meaning. The method reveals that cinema is not transparent communication but a complex coded system where understanding requires learning film's specific sign conventions.	Discourse Analysis in Media is a method for examining how media texts use language, images, and communication patterns to construct meanings, shape identities, and perpetuate or challenge power relations. Developed from linguistic analysis and critical theory—particularly Michel Foucault's concept of discourse as a system of knowledge-production and Norman Fairclough's critical discourse analysis (CDA) framework—the method reveals how what appears as neutral information or entertainment actually participates in maintaining or challenging social hierarchies and ideologies. The method is specifically concerned with how discourse operates politically: what it makes possible to think and say, whom it privileges, and what alternatives it renders invisible.
