概要	Multiple case-based metaphor analysis is a qualitative comparative method that systematically identifies and interprets metaphorical language across two or more bounded cases — such as schools, organisations, or participant groups — to reveal how people in different contexts conceptualise a shared phenomenon. It integrates Lakoff and Johnson's conceptual metaphor theory with Yin's multiple-case logic, enabling both within-case depth and cross-case breadth.	Content analysis is a systematic research technique for reducing text, visual, or media material into coded categories so that patterns can be counted, compared, and interpreted. Formalised by Klaus Krippendorff in his widely cited methodology textbook (latest edition 2018), the method sits at the boundary of qualitative and quantitative inquiry: it imposes structured, replicable coding on inherently meaning-laden material.
