概要	Field-based semiotic analysis is a qualitative approach that combines sustained fieldwork observation with systematic semiotic analysis of signs, symbols, and meaning-making practices encountered in a natural setting. Drawing on the social semiotic tradition of Hodge and Kress, the researcher enters a social field, records its multimodal sign systems — including visual, spatial, gestural, and textual elements — and interprets how participants use and negotiate signs to construct social meanings.	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.
