概要	Field-based life history research is a qualitative design that combines sustained ethnographic fieldwork with in-depth biographical interviewing to reconstruct how individuals have experienced and given meaning to their lives within particular social, cultural, and historical contexts. Unlike archive-only biographical work, the field-based variant requires the researcher to be physically present in the participant's social world over time, gathering both spoken life stories and observational data from that world.	Grounded Theory (GT) is a systematic qualitative research methodology in which theory emerges directly from data through iterative analysis, rather than being imposed before data collection. Developed by Barney Glaser and Anselm Strauss in 1967, GT prioritizes generating explanatory frameworks grounded in evidence.
