概要	A multiple case-based single case study — also called an embedded single-case design — is a qualitative strategy in which a researcher investigates one bounded case (the primary unit of analysis) by systematically examining multiple embedded sub-units within it. Rather than studying several separate cases for comparison, the design focuses all analytical attention on one overarching case while using variation across its internal sub-units to build a richer, more robust understanding of that single case.	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.
