Projects aimed at recording the unique values and characteristics of geographical regions, in terms of human, social, and economic aspects, have been increasing in number, along with plans to apply these data to future planning directions. However, such projects tend to develop gradually and in a uniform direction, contrary to its original intention. To address these problems, a survey method with consideration for regional characteristics is presented here. In addition, after local lifestyle is investigated, more effective procedures are needed to ensure that outcomes are actively utilized in local revitalization plans and that residents can access and use the data. This study proposes improvement directions for the South Korean context via examination of the progress, characteristics, and limitations of utilization of the results of such life-culture projects, based on a multiple case analysis of these projects in Seoul.
