概要	Longitudinal phenomenology applies phenomenological inquiry across two or more time points to capture how participants' lived experience of a phenomenon changes, deepens, or transforms over time. Rooted in the phenomenological tradition of Husserl and Heidegger, it adds an explicit temporal dimension — asking not only what an experience is like, but how it evolves. It is used where a single-point interview would miss the processual, shifting nature of lived meaning.	Hermeneutic phenomenology is a qualitative research approach that investigates the interpreted meaning of lived experience from within the existential conditions that shape it. Rooted in Heidegger's ontology and developed as an empirical method by Max van Manen, it does not seek to bracket or suspend the researcher's understanding but instead treats that understanding as the very medium through which the meaning of experience can be disclosed. The approach is widely used in education, nursing, and social sciences to explore how people dwell in, and make sense of, their world.
