A number of cities are committed to enhancing the barrier-free (BF) environments. However, no attempts have been made to examine the BF environment design concept by accounting for the universal BF components, which should be improved for providing both disabled people and non-disabled people with better BF environments. With this challenge in mind, this study determines the improvement priorities of BF components for beaches in the city of Busan by investigating the results of satisfaction survey, which was administered to disabled and non-disabled visitors. The modified importance-performance analysis (M-IPA) results show that "sanitation facilities" are the universal BF components having the highest improvement priority. The analysis results also indicate that "access facilities" have the second highest improvement priority for disabled people while "amenity facilities" have the second highest improvement priority for non-disabled people. It is highly expected that the suggested improvement priorities of BF components can be used for policy makers to develop more flexible plans when designing the BF beach.

For effective improvement of water quality in Seokmun reservoir, this study implemented various analyses including the tributary water quality and flowrate monitoring, contamination of sediment, investigation of pollution source, selection of priority management target tributary by stream grouping method. The COD concentration of the majority of tributaries in Seokmun reservoir watershed was relatively higher than BOD concentration. The concentration of water pollutants regardless of water quality parameters in Yeokcheon, Dangjincheon, Sigokcheon, Baekseokcheon, small stream in Jinkwanri and Janghangri were higher than the other tributaries. The pollution sources in the Seokmun reservoir watershed were mostly distributed in the population, livestock, and industry. The pollutants, which located in Yeokcheon, Dangjincheon, Baekseokcheon, and small stream in Janghangri selected as priority management target tributary, should be preferentially reduced for improving the water quality in Seokmun reservoir. As the evaluation results of water quality in Seokmun reservoir for the effect of water quality improvement according to various scenarios using water quality model, it was found that the water quality in Seokmun reservoir due to the construction of a wastewater treatment plant for management of pollutants in the watershed would be satisfied the class V of water environment standard in reservoir.
