概要	Participatory ethnography is a qualitative research design in which community members are not merely subjects of study but active collaborators throughout the research process — from problem formulation and data collection to analysis and writing. Building on classical ethnographic fieldwork, it shifts the researcher–participant relationship toward genuine partnership, producing knowledge that is accountable to the communities from which it emerges.	Case study research is a qualitative research design that investigates a specific phenomenon, individual, group, organisation, or event in depth within its real-world context. Systematised by Robert K. Yin in 1984, it supports single-case and multiple-case designs and draws on multiple data sources — interviews, observation, documents, and artefacts — to build a rich, contextualised account of a bounded unit.
