With the recent improvement in the quality of life and cultural level for the people, the central and local governments take interest in activation of culture and arts; however, there have been absolutely insufficient spaces for practicing performing arts by now. So the government tries to make greater use of idle public facilities, which have been neglected, aged, for years, and provide stable practice spaces in support of creative activities of local arts groups. The development of such idle public facilities into performing arts practice spaces requires security of acoustic performance appropriate for their use as well as improvement of the aged facilities. From this perspective, this study aimed to determine the degree of improvement and changes in acoustic performance following remodeling of Chuncheon Girls" High School, which has recently been remodeled, on the basis of the data from the previous research. The data from this study are expected to be useful in remodeling similar performing arts practice spaces.

In this study, we aimed to identify changes in fire resistance according to the type of sleeves used for pipe penetrations and to examine their accreditation of fire resistance performance and use them as basic data. The test results of fire resistance according to the type of sleeve used in non-metallic pipe facilities showed that the temperature on the support side was higher for sleeves with higher thermal conductivity. For the temperature on the surface of the pipes, in the case of galvanized steel plates, steel pipes, and structures without sleeves, the highest temperature was observed after the expansion of the firestop material for 46 to 53 minutes and then decreased. PVC sleeves showed a steady increase in temperature until 53 minutes, after which the temperature did not increase further. In addition, for non-metallic pipes, the effect of the type of sleeve on fire resistance is considered to be insignificant because the lower part (heating direction of the furnace) under the support structure is cut off to block the heat during the two-hour fire resistance test.

The public facilities established with the rapid urbanization since the 1960s have gradually been neglected due to the changes in various social conditions, causing serious social problems. So the central and local governments have recently tried to remodel such idle public facilities into performing arts practice spaces and use them as cultural facilities and community spaces, which are insufficient at the local level. Remodeling into performing arts practice spaces requires diverse types of revision of space elements, including partitioning or integration of the existing spaces; moreover, it is difficult to secure the certain level of acoustic performance. However, South Korea has almost no relevant data and has lots of difficulty at the design and construction stages. From this perspective, this study aimed to analyze the changes in space elements following remodeling of recently remodeled performing arts practice spaces in five regions. This study is expected to provide basic data useful to revise space elements and secure acoustic performance in remodeling performing arts practice spaces.
