요약	Oral history is a qualitative research method that collects, preserves, and interprets first-person spoken accounts of past events, experiences, and social processes. By recording in-depth interviews with individuals who witnessed or participated in historical events, oral historians document perspectives that written records often exclude. The method bridges historical scholarship and social science, treating the narrator's memory, subjectivity, and voice as primary evidence rather than as limitations to be corrected.	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.
