概要	Field-based ethnography is a qualitative research design in which the researcher immerses themselves in a social setting or community over an extended period, observing and participating in everyday life to understand cultural practices, meanings, and social dynamics from an insider perspective. It is the classical form of ethnography, grounded in sustained physical presence at a research site, and distinguished from archival, virtual, or document-only approaches by its central reliance on direct, embodied fieldwork.	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.	Ethnography is a qualitative research tradition in which a researcher immerses themselves in a social group or community over an extended period — typically three to six months or longer — to study its culture, values, and behaviours in their natural setting. Originating in social and cultural anthropology, and consolidated as a rigorous method by Bronisław Malinowski in the early twentieth century, ethnography produces rich, contextualised accounts of how people live, work, and make meaning together.
