概要	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.	Grounded Theory (GT) is a systematic qualitative research methodology in which theory emerges directly from data through iterative analysis, rather than being imposed before data collection. Developed by Barney Glaser and Anselm Strauss in 1967, GT prioritizes generating explanatory frameworks grounded in evidence.
