Purpose: The purpose of this study was to compare the effect of alcohol gel according to the amount and drying time in health personnel hand hygiene and to promote in their practice adequate and effective hand hygiene. Methods: The crossover experimental study was performed with 14 volunteers. Hands were artificially contaminated with 5 mL of $10^8$ CFU/mL of Serratia marcescens (ATCC 14756) and four different alcohol gel hand hygiene methods varying by the amount of alcohol gel (2 mL vs. 1 mL) and drying time (complete vs. incomplete) were compared. Samples were collected by glove juice sampling procedures. Results: Mean log reduction values of the four different hand hygiene methods were $2.22{\pm}0.36$, $1.26{\pm}0.53$, $1.49{\pm}0.60$, $0.89{\pm}0.47$ respectively for the 4 groups: adequate amount (2mL) and complete dry (30 seconds rubbing followed by 2 min air-dry), inadequate amount (1 mL) and complete dry, adequate amount and incomplete dry (15 seconds rubbing and no air-dry), and inadequate amount and incomplete dry. The difference was statistically significant in the adequate amount and complete dry group compared to other three groups (p<.001). Conclusion: Only alcohol gel hand hygiene with adequate amount and complete drying was satisfactory by U.S. FDA-TFM efficacy requirements for antiseptic hand hygiene products.

Background & objectives: This study was aimed to identify the hand hygiene (HH) compliance and related factors among teachers working at child day care centers. Method: This study was done with 44 teachers working at home child day care center in Changwon. Data on hand hygiene compliance was measured using direct observation method from July to December, 2016 with structured observation sheet. Collected data was analyzed by descriptive statistics, and t-test or ANOVA using SPSS Statistics version 23.0. Result: Complete HH compliance rate was 54.0%, the highest in 'before having meals' (81.6%) and the lowest in 'after having meals' (25.8%). However, incomplete HH compliance rate was 34.5%, the highest in 'after contact with secretions' (47.8%) and the lowest in 'before having meals' (18.4%). The HH rate was related with working experience. Conclusion: The HH compliance rate among child care teachers was not satisfactory. About one quarter of child care teachers have taken hand hygiene related training. Therefore, child care teachers should be encouraged to participate in hand hygiene related education program regularly.

Objectives: The purpose of this study was to investigate nail hygiene behaviors and to identify the relationship between hand hygiene beliefs and nail hygiene behaviors among dental hygienists, dental's aide and dental coordinator in South Korea. Methods: The subjects were 291 dental workers including dental hygienists, dental assistant and dental coordinator working full-time at dental clinics, dental hospitals, general dental hospitals and dental university hospitals in Seoul, Incheon, and Gyeonggi-do. The questionnaire consisted of a total 35 items, including 4 items on general characteristics, 25 items on hand hygiene, 2 items on "nail art" experience, and 4 items on nail hygiene behaviors. The collected data were analyzed using an independent t-test, one-way ANOVA, chi-square test, correlation analysis, and multiple linear regression analysis, where ${\alpha}<0.05$ was considered statistically significant. Results: The scores of behavioral beliefs, normative beliefs, control beliefs and nail hygiene behaviors were $5.15{\pm}0.58$, $5.26{\pm}0.81$, $3.69{\pm}0.96$ and $5.03{\pm}0.98$, respectively. Statistically significant relationships were detected in terms of participants' clinical experiences with respect to behavioral and normative beliefs (p<0.05 for all three belief categories). Participants working in general dental hospitals and dental university hospitals demonstrated the highest scores for behavioral, normative and control beliefs (p<0.05). Participants working in dental clinics reported the highest "nail art" experience rates in the last two years (45.5%) and at the time of the survey (15.7%; p<0.05). Nail hygiene behaviors were more likely to be observed in individuals with stronger behavioral and stronger normative beliefs (p<0.05). Conclusions: More specific infection control guidelines for "nail art" among dental workers should be established and promoted, so that both patients and dental workers can interact in a safe environment.

Objectives: This study was performed in order to investigate hand hygiene practices among food-service businesses employees based on the awareness of hand-washing and load of indicator bacteria on their hands. It focused on the comparison of full-time and part-time workers in food-service workplaces. Methods: A direct-interview questionnaire survey and microbiological analysis were carried out with sixty workers each. Samples for microbiological analysis were collected through a modified glove-juice method from the hands of the food-service workers and were analyzed for aerobic plate count, total coliform, fecal coliform, Escherichia coli, Staphylococcus aureus, and Salmonella spp. Microbiological analysis was done according to the Food Code of Korea. Results: Significant differences (p<0.01) were found in the survey between the full-time and part-time workers in hand-washing frequency, use of hand-washing agents, and hand-drying methods. More full-time workers responded to washing their hands after preparing food, after visiting outside, after handling raw materials, and before putting on gloves/when changing gloves than did part-time workers (p<0.05). No remarkable difference was found in bacterial load on the hands except in the aerobic plate count between the two groups. The detection of E. coli, S. aureus, and Salmonella spp. on the hands of some food-service workers in both groups revealed poor hand hygiene practices. Conclusions: The results of this study indicate that there is a need for training programs in order to improve hand hygiene practices and strict hand hygiene compliance by food-service workers.

Objectives: This study was performed to investigate hand washing awareness of females and load of indicator bacteria on their hands. This study focused on the variation according to their age. Methods: A self-administered questionnaire survey and bacterial analysis of indicator bacteria were carried out for 100 Korean women in their age from 20 s to 60 s. Hand samples were collected through a modified glovejuice method. Results: In the survey, significant difference (p < 0.05) was found among the age groups in the use of hand washing agents. The levels of aerobic colony count (ACC) were the highest in both hands among the 20s (p < 0.05). The levels of Escherichia coli were higher in both hands in their 20s and 30s. No significant difference was found in the levels of Staphylococcus aureus and Salmonella spp. However, the positive rates of S. aureus (left hand, 37.5~47.1%; right hand, 58.5~62.5%) and Salmonella spp. (left hand, 25.0~52.9%; right hand, 37.5~64.7%) were higher in the hands of the 20s and 30s, and then showed decreasing trend according to increase of age. The effect of hand washing frequency on the ACC level of hands was significant (p < 0.001). Conclusions: These results indicate that there was no remarkable difference of hand hygiene awareness among female age groups. The detection of S. aureus and Salmonella spp. on the hands of some females in each age group revealed poor hand hygiene practices. The significant effect of hand washing frequency on the ACC level suggests that frequent hand washing is helpful to reduce hand contamination.

Objectives: The purpose of this study was to investigate the hygiene behaviors according to obesity in adolescents and to provide basic data for school health project. Methods: The data from the 10th Korea Youth Risk Behavior Web-based Survey(KYRBWS) were analyzed by STATA 13.0 statistical packages. The demographic characteristics were analyzed by frequency analysis. The relationship between obesity and hygiene behaviors according to demographic characteristics were analyzed by chi-square test. Pearson's correlation coefficient was used for the correlation among the variables. Multivariate logistic regression analysis was performed to examine the effect of obesity on the hand washing and oral hygiene behaviors. The significance level for significance was set at 0.05. Results: Obesity, hand washing before eating and hand washing after using the bathroom were significant negative correlation. Hand washing before eating and hand washing after using the bathroom were significant positive correlation. Hand washing after using the bathroom were positive correlation with toothbrushing after lunch. Washing before eating was 1.079 times higher than that of obese people(p<0.05), and toothbrushing after lunch was higher by 1.298 times in Odds ratio than normal weight(p<0.001). Conclusions: There is a need to develop a school dental health program by collecting hygiene behaviors such as obesity, hand washing, and brushing after lunch.
