  • The purpose of this study is to examine the improvement of the slipperiness of building floors and to test the safety in accidental collision in the primary schools. To perform this purpose effectively, the actual 20,202 cases of accident on the year 2000-2009 which had been dealt by Seoul School Safety and Insurance Association were analysed in several aspects. And to test the current slipperiness and hardness of building floors, 3 primary schools whose construction year differed were examined. This study found that among the indoor accidents of 2,646 cases on the year 2000-2002, 70.7% accidents of them were caused by slipperiness. It was also found that the building floors of the primary schools could not be safe from the result of examining the slipperiness and hardness of the building floors. As the result of this study, it showed that the desirable efficient criterion of slipperiness would be more than C.S.R 0.4, and that of safety in accidental collision would be less than Gs 100G for the safety of primary school students.

  • Since the study of building performance design was first undertaken by Building Research Station in 1930s, the results of such study has been reported from many parts of the world, building construction codes and standards have been revised based on performance in advanced nations as well in Korea, and various performance certification systems are in operation. The purpose of this study is to build a database of performance certification systems to investigate the co-relationship of various test methods related to the same test items. As test methods for case study, we selected test methods involving collision of the human body. Through analysis of Critical fall height test of EN 1177 and Head Model test of JIS A 6519 about 8 species of floor test-bodies, it was found that there are limits of application in terms of the depth and strength of cushion. Furthermore, although the measured physical parameters are the same, when the co-relationship between test methods is uncertain, the various physical parameters may not be compatible with the results.
