This article explores the application of innovation–diffusion theory to tactical urbanism projects. The objective of the study is to comprehend how innovation–diffusion theory can be utilized to analyze and evaluate these projects and identify the factors contributing to their success. The research was conducted through a collaborative design studio experience, using qualitative methods that largely depended on participatory observations and interviews with key participants. The findings indicate that the Innovation–Diffusion theory can serve as a comprehensive theoretical framework for the analysis and evaluation of tactical urbanism projects. The study also identified factors that contribute to the success of these projects, such as the involvement of opinion leaders, the use of low-cost and temporary interventions, and the flexibility to adapt to on-site variables.

This study investigates the changes in regional disparities in primary healthcare in South Korea during the COVID-19 pandemic. Our descriptive analysis found that the supply of primary healthcare per capita by the private sector decreased in all regions in 2020, at the beginning of the pandemic. In the following years, the supply of private clinics in the Seoul Metropolitan Area and other metropolis cities increased compared to before COVID-19. However, the rate of increase in private clinics per person in small and medium-sized cities/rural areas (SMRs) was relatively low. The supply of private clinics for essential medical subjects decreased in SMRs compared to pre-COVID-19. The regional disparity in primary healthcare between metropolis cities and SMRs has worsened during the pandemic. The deepening regional disparities in access to primary healthcare, which are evaluated as the long-term footprint of COVID-19, could result in inequalities in health outcomes.
