概要	Participatory Digital Ethnography (PDE) is a qualitative research design that combines the immersive observation of digital ethnography with the collaborative, co-inquiry stance of participatory action research. Researchers work alongside community members within digital environments — social media platforms, online forums, gaming worlds, or hybrid digital-physical spaces — co-producing knowledge rather than studying participants from a detached observer position.	Netnography is a qualitative research method that adapts the principles of cultural ethnography to the study of online communities and social media environments. Coined by Robert Kozinets in 1997 and systematised in his 2010 handbook, netnography treats digital spaces — forums, social networks, blogs, review sites — as naturally occurring field sites where communities gather, share meanings, and construct identities. The method combines unobtrusive observation of digital traces with active participation and, where appropriate, direct member interaction.
