영문 초록

The aim of this study is to examine size-based concentration and genera of airborne fungi distributed in public facilities such as hospital, kindergarten, day-care center and postpartum nurse center and to provide fundamental data in order to prevent respiratory diseases caused by exposure to airborne fungi. Culturable total and respirable concentrations of airborne fungi averaged to 382 cfu/m3 and 292 cfu/m3 in hospital, 536 cfu/m3 and 347 cfu/m3 in kindergarten, 334 cfu/m3 and 266 cfu/m3 in day-care center, and 371 cfu/m3 and 289 cfu/m3 in postpartum nurse center, respectively. The ratio of respirable to total concentration of airborne fungi in the investigated public facilities was ranged from 55% to 70% but there was no significant difference among them (p>0.05). The mean I/O ratio of culturable total and respirable concentrations were 0.56 and 0.64 in hospital, 0.72 and 0.91 in kindergarten, 0.33 and 0.45 in day-care center, and 0.63 and 0.73 in postpartum nurse center, respectively. Indoor concentration of airborne fungi did not correlated significantly with indoor temperature and relative humidity (p>0.05) but had a significant positive correlation with CO2 concentration (p<0.01) and surrounding condition (p<0.05). Penicillium spp., Cladosporium spp., and Aspergillus spp. were estimated to over 95% of total airborne fungi identified in the investigated public facilities.
