概要	A field-based single case study is a qualitative research design that investigates one bounded real-world case — an individual, program, organization, event, or community — in its natural setting through sustained first-hand fieldwork. Drawing on Robert Yin's systematic case study logic and Robert Stake's interpretive tradition, this design combines multiple data sources collected on-site to build a rich, contextualized account of a phenomenon that cannot be separated from its real-world environment.	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.
