This study sought to identify social problems in Busan and find solutions through Busan-type appropriate technology. To this end, in-depth interviews with expert FGI (5 times), in-depth interviews with socially disadvantaged and marginalized groups (elderly, disabled, youth), and in-depth interviews with caregivers/expert groups were conducted. A demand survey was conducted to solve social problems in Busan using appropriate technology. In addition, a demand survey was conducted among the elderly, the disabled, and young people, and found various problems in housing, medical care, and information transmission. We have derived an appropriate technology to solve this problem. First, improving housing, strengthening and disseminating access to medical technology, information transmission. It should help ease interpretation (elder problem). Second, appropriate technology should be used to improve citizens' awareness, guarantee the right to movement, and facilitate emergency medical requests (disability issues). Third, appropriate technology should be applied to make use of vacant houses and use sustainable energy to make housing stable and enjoyable work (youth problem).
