概要	Longitudinal oral history method is a qualitative research design in which the same participants are interviewed repeatedly over an extended period — months or years — using oral history interviewing techniques. By returning to narrators across time, researchers can trace how personal accounts, identities, and interpretations of experience shift and evolve, capturing the processual and biographical dimensions of social life that a single interview cannot reveal.	Phenomenology is a qualitative research approach that investigates how participants live through and make sense of a specific experience. Rooted in the philosophy of Edmund Husserl and extended by Martin Heidegger, it aims to reveal the essential structures of lived experience rather than to measure or predict outcomes. The two most widely applied variants are Husserl's transcendental phenomenology, which seeks universal essences, and Heidegger's hermeneutic phenomenology, which emphasises interpretation within context.
