We studied on the effect of faucet cleanliness, faucet conditions (screen, mixing faucet), and flushing time for bacterial detection in tap water. As results, tap water should be left to run to waste for 2 to 3 minutes and if a questionable cleanliness is questionable, disinfect the faucet by using flaming or other methods before sampling. We proposed sampling method to decrease effect of factors associated with bacterial detection in tap water and contributed to be evaluated more accurate water quality.

This study collected opinions about the design and management of toothbrushing facilities from schoolteachers and the people in charge of public centers, through a focus group interview (FGI), for the development of guidelines. Four moderators conducted eight FGIs of 32 subjects in charge of toothbrushing facilities across all the regions. The qualitative data was analyzed by constant comparative analysis. The findings indicated that more students utilized the facility and brushed their teeth after the installation of toothbrushing facilities. To enhance students' accessibility and safety, guidelines for design and management guidelinesfor toothbrushing facilities need to be developed; the location, sink height and depth, drain size, etc. should be comprehensively considered in the development of the guidelines. This study can help to improve students' satisfaction by enhancing the accessibility, safety, and functionality of toothbrushing facilities, and by providing fundamental data for toothbrushing facilities' development. Finally, this study can maximize the effects of management of toothbrushing facilities management on the improvement of students' oral health and behaviors.
