요약	Visual elicitation case study is a qualitative design that embeds photo or image elicitation within a case study framework. Participants respond to photographs, drawings, or other visual materials during in-depth interviews, generating richer and often unexpected data than verbal questioning alone. The case study structure then situates these image-prompted accounts within a bounded real-world context — an individual, organization, community, or event — enabling a holistic, detailed understanding of the case.	Participatory Action Research (PAR) is a qualitative, community-centred methodology in which researchers and community members collaborate as co-investigators to identify a shared problem, take deliberate action, observe outcomes, and reflect critically on results — cycling iteratively until meaningful change is achieved. Unlike conventional research that studies people from the outside, PAR treats participants as active agents who co-own the research process, the knowledge produced, and the practical interventions that follow.
