This study aimed to culturally adapt and validate the Satisfaction with Assistive Technology Service (SATS) instrument for the South Korean context, addressing the unique needs of assistive technology users and enhancing service-satisfaction evaluation. Following "Principles of Good Practice" guidelines, the SATS was translated into Korean, involving forward and backward translation, cognitive debriefing, and pre-testing with AT users and professionals. Reliability and validity were assessed through internal-consistency measures, test-retest reliability, and concurrent-validity comparison with the Quebec User Evaluation of Satisfaction with Assistive Technology, Korean version. The SATS-K demonstrated high reliability and validity, with a Cronbach's alpha of 0.94 (<i>p</i> < 0.01). The test - retest reliability, indicated by the intraclass correlation coefficient, was 0.92 (<i>p</i> < 0.01). Furthermore, the Pearson coefficient of the correlation between the SATS-K and the QUEST-K scores was 0.934 (<i>p</i> < 0.01), highlighting strong concurrent validity. The version showed notable distinctions in "instruction & training" satisfaction compared to European versions. Despite the potential statistical benefits of excluding the "waiting time" item, its retention was deemed crucial for capturing comprehensive service-satisfaction insights, particularly for highlighting the need for addressing service-delivery times. The SATS-K provides a culturally and linguistically adapted tool for evaluating AT-service satisfaction, offering significant insights for service improvement.

These findings highlight the need for a comprehensive approach to preparing aging individuals with disabilities for later life.

As a city is urbanized, its landscape becomes more complex owing to the construction of high-rise buildings. The small scale wind-field in an urban district may change frequently owing to the complex terrain, the diverse land use, and high-rise buildings. It also leads to dynamic changes in the air pollution in that area. Conventional urban-scale air quality management systems, however, are unable to effectively manage detailed aspects of such changes. In this study, we set up a micro-scale air quality management system (MAMS) testbed over Konkuk University, Seoul, Korea. A wireless sensor network and a CFD modeling data management system were combined to support the MAMS sensor service. The sensor-based monitoring system showed reasonably good performance for temperature, humidity, and carbon dioxide from inter-comparison studies against conventional large format analyzers. However, the real-world application of a sensor network for air quality monitoring has many limitations, such as limited installation points for 3-dimentional monitoring, limited power availability for continuous monitoring, and limited sensitivity to ambient concentrations. We therefore developed the concept of a “virtual sensor†to provide micro-scale personal air pollution information services, using a CFD-based air quality modeling system. Based on the information provided by the virtual sensors, we developed a futuristic air quality service of the MAMS application for the mobile platform. We found that the combination of CFD-based modeling data with a fast large volume data management system and a mobile visualization system will be a successful intermediate solution for a user-based air quality service before an actual ubiquitous sensor-based system is available to produce micro-scale environmental information for entire urban areas.
