概要	Multiple case-based discourse analysis is a qualitative research design that applies systematic discourse analysis within each of two or more purposively selected cases, then compares the discursive patterns, themes, and power relations across those cases. It combines the replication logic of Yin's multiple case study methodology with the text- and talk-centred analytical tools of discourse analysis traditions such as critical discourse analysis or conversation analysis, enabling researchers to build comparative, theoretically grounded accounts of how language constructs social reality across different contexts.	Thematic Analysis (TA) is a qualitative research methodology for identifying, analyzing, and reporting patterns (themes) in qualitative data. Developed systematically by Virginia Braun and Victoria Clarke (2006), TA is flexible and accessible, applicable across diverse theoretical frameworks and data types, making it one of the most widely used qualitative methods in psychology, health research, and social sciences.
