The use of copper antibacterial films as an effective infection prevention method is increasing owing to its ability to reduce the risk of pathogen transmission. In this study, we evaluated the bacterial contamination of the antibacterial copper membrane attached to a door handle at a university over time. Six mounting locations with high floating population were selected. In three sites, the door handles with the antibacterial film were exposed, while the remaining three were not attached with the antibacterial films. On days 7 and 14, isolated bacterial strains were inoculated in BHI broth and agar, respectively. Colony-forming units (CFU) were determined after incubation. Strain identification was performed using bacterial 16s rRNA PCR and sequencing. Results showed that the bacterial population on day 14 significantly increased from 6 × 10⁹ CFU/mL (day 7) to 2 × 10¹⁰ CFU/mL. Furthermore, strain distribution was not different between the on and off the copper antibacterial film groups. In conclusion, although copper has an antibacterial activity, microbial contamination may occur with prolonged use.

The purpose of this study were to investigate smoking status and management and knowledge of oral health, to provide basic data of giving up smoking policy for oral health management and oral health educational program. 268 self-reporting questionnaire were collected from March 3, 2010 to March 10, 2010. The results were as follows; (1) As to compare department, the answers of that in health science department were 38.3% and the other department were 44.3%, however it was shown statistically significant correlation(p>0.001). (2) As to compare department, the answers of that in health science department were 50.8% and the other department were 68.6%(p<0.007). (3) As to compare department(p<0.00), the answers of that in health science department were 36.7% and the other department were 55.0%, smoker group and non-health science department group were higher than that of the others(p<0.014).
