Purpose: The purpose of the study was to investigate hand washing practice and proper hand cleansing among first and second year nursing students who are prone to be exposed to nosocomial infections, and to identify the influence of perceived behavior control and self-efficacy on hand washing practices and proper hand cleansing. Method: Data for 91 students were collected from a nursing college in a metropolitan city in Korea. Data were analyzed using descriptive, t-test, one way ANOVA, Pearson correlation coefficient, and multiple regression with SPSS/WIN 19.0. Result: The mean score for hand washing practice was 38.35 out of a possible score of 48, and the mean sore for proper hand cleansing was 18.63 out of a possible score of 28. The significant factors affecting student hand washing practice were 'residential type' (p=.016), 'perceived behavior control' (p=.021), and 'self-efficacy' (p=.033) which explained 19.9% of the variance. The significant factors affecting proper hand cleansing by the students were 'perceived behavior control' (p<.001) and 'regular exercise' (p=.026) which explained 29.8% of the variance. Conclusion: These results indicate a need for education programs on hand washing including strategies to improve perceived behavior control and self-efficacy to promote more effective hand washing practices.

Changes in laundering habits and the efficacy claims made for oxygen bleach added to detergents necessitate a deeper investigation into the testing of the washing efficacy of detergents and washing process. The effect of the addition of a sodium percarbonate and bleach activator TAED to an enzyme containing detergent on the soil removal and antimicrobial properties were investigated with the measuring of residual H$_2$O$_2$. The addition of sodium percarbonates to enzyme containing detergent lowered the soil removal of EMPA 116 cloth. But sodium percarbonates had greater effects on that of colored stained cloths such as EMPA 115 and artificially soiled with wine and red pepper while they were presoaked at 20$^{\circ}C$ or higher for So minutes or longer. Most of hydrogen peroxide was remained after washing. Over 99.9% of Staphylococcus aureus on the cotton cloth was removed in every washing solutions, but the cloth washed with enzyme containing detergent or detergent with oxygen bleach didn't show the antimicrobial property.

Purpose: This study aimed to analyze factors affecting the handwashing performance of nursing students using the health belief model, self-efficacy, and handwashing attitudes. Methods: Data were collected using structured questionnaires in 2018. 223 students enrolled in nursing college participated in the questionnaire, which consisted of four sections: health belief in hand washing, self-efficacy, hand washing attitude, and general handwahsing characteristics. Data were analyzed using t-test, ANOVA, correlation coefficient and multiple regression analysis with SPSS 21.0 statistical programs. Results: The significant predictors affecting proper hand cleansing were perceived benefits and motivation of health belief model, handwashing time and frequency, and handwashing attitude. Out of these significant variables, perceived benefits was shown to be the strongest predictor. Conclusion: The findings suggest that periodic and steady hand washing training programs need to be implemented in order to improve handwashing practices of nursing students. Such handwashing education programs should include content that sensitizes the benefits of hand washing and provides information on how to carry out hand washing in detail.

The hand hygiene behavior of 400 middle school students (grades 1-3) in Seoul and Gyeonggi-Do was studied to determine how stages of change were affected by food safety education, focusing on hand hygiene and general food safety. Subjects were 51.3% male and 44.3% of study subjects were first graders of middle school. Approximately 40% of subjects were at the stage of action, 42.7% were at the stage of contemplation, and 16.4% were at pre-contemplation. The most important factor that influenced proper hand washing was self efficacy ($P$ < 0.001). Proper hand washing was also correlated significantly with positive belief ($P$ < 0.01) and stages of change ($P$ < 0.01). After food safety education by high-school mentors, middle-school students who were in the stages of pre-contemplation (11.1%) and contemplation (88.9%) showed significant progression toward the action stage ($P$ < 0.001). Proper hand washing ($P$ < 0.01) and food safety knowledge ($P$ < 0.05) were also significantly increased after educational intervention.

Purpose: The purpose of this study is to identify factors related to compliance with respiratory infection preventive behaviors including hand washing, cough etiquette, and oral hygiene of older adults. Methods: A cross-sectional study was conducted with a convenience sample of 100 older adults (mean age: $76.11{\pm}6.35$ years, female: 86.0%). Data were collected from a community senior center through face to face interviews by using instruments including measuring knowledge, perceived threat, self-efficacy, compliance with respiratory infection preventive behaviors. Results: The mean score of knowledge was 7.52 out of 13 in total. The compliance with hand washing with soap was 6.0% for 8 or more times per day. Among the participants, 12.0% adhered to the cough etiquette. Sixty-two older adults (62.0%) didn't use interdental brushes or floss at all. The stepwise linear regression indicated that age and self-efficacy for respiratory infection preventive behaviors were significant factors and explained 24.0% of the compliance with hand washing and the cough etiquette. Education level, cancer diagnosis, and self-efficacy for respiratory infection preventive behaviors were significant predictors of oral hygiene. The factor with the greatest effect was self-efficacy in the two models. Conclusion: The findings suggest that it is necessary to improve compliance with respiratory infection preventive behaviors among older adults using senior centers. In order to enhance the compliance, it is necessary to develop nursing programs based on the self-efficacy for respiratory infection preventive behaviors in the senior centers.

The purpose of this study was to compare the hand disinfection effect of waterless alcohol gel hand washing agent with that of soap and water, 4% chlorhexidine gluconate, and 10% povidone-iodine. Hands of fourty subjects were artificially contaminated with Acinetobacter baumannii $5m{\ell}$ and randomly distributed to each hand washing methods. Samples were collected from gloved hand by glove juice sampling procedure. Mean log reduction after hand washing were compared with baseline values. Number of microorganisms were converted to log and tested by ANOVA in SPSSWIN 10.0. Mean log reduction of soap and water, alcohol gel, 4% chlorhexidine gluconate, 10% povidone-iodine were $2.76{\pm}0.62$, $2.97{\pm}0.56$, $4.66{\pm}1.70$, $4.60{\pm}0.91$, respectively. The bactericidal effect of alcohol gel was similar to that of soap and water, but the effect was much less than chlorhexidine gluconate and povidone-iodine(p<0.001). In terms of microorganism reduction, the efficacy of waterless alcohol gel was almost the same as soap and water hand washing. Further evaluation of the bactericidal effect of waterless alcohol gel is needed because waterless alcohol gel is simple, convenient, and non-irritating hand washing agent and also very effective in busy hospital environment.

In this study, the efficacy of ultrasonic washing in cotton and wool fabrics was compared and evaluated against conventional washing in terms of cleaning properties and fabric deformation. Factors such as washing temperature, time, liquid ratio, and detergent concentration were kept varied, and the cleaning properties of sebum-soiled fabrics were assessed using different detergents such as alcohol ethoxylate, linear alkylbenzenesulfonate, and IEC 60456 Reference Detergent A^*. In addition, the effects and emulsification power of enzymes and oxygen bleach were examined. To compare the cleaning properties with general washing, a launder-O-meter was used. To investigate fabric deformation during the washing process, the loosening test cloth, shrinkage test cloth, and mechanical strength test cloth were compared between ultrasonic washing machines and household drum washing machines. The results indicate that ultrasonic washing exhibits superior cleaning properties than launder-O-meter when the temperature is low and the washing time is short. Furthermore, there is less deformation and damage during the washing process. It was also observed that the activity of the detergent increases when ultrasonic waves are applied to the washing process. Considering the increasing tendency to pursue convenience and simplicity in clothing management as well as the anticipated commercialization of smart clothing with built-in electric circuits, ultrasonic laundry could serve as a new alternative to existing laundry methods.

This study was conducted to evaluate the odor reduction efficacy of the dip injection wet scrubber (DIWS) using tap water as washing fluid. The $NH_3$ and $H_2S$ removal efficiency of 7 day batch operated DIWS was evaluated twice over a total of 14 days of experiment. The $NH_3$ removal efficiency ranged from 26 to 37%. The $H_2S$ removal efficiency was between 22 and 30%. The pH of the washing fluid maintained below 8 and the $NH_4{^+}$ concentration tended to keep constant around 350 ppm after 5 days of washing-fluid replacement. Therefore, the 5-day washing fluid replacement interval is more preferable than the 7-day interval. The $NH_4{^+}$ concentration and the electrical conductivity (EC) showed a high correlation. The EC measurement can be used as an alternative to conventional $NH_4{^+}$ concentration measurement method for real time monitoring of washing fluid condition.

The use of suitable sanitizers can increase the quality of fresh-cut produce and reduce the risk of foodborne illnesses. The objective of this study was to compare the washing effects of 100 mg/L sodium hypochlorite (SH) and 500 mg/L acidified sodium chlorite (ASC) on the prevention of enzymatic browning and the growth of microbial populations, including aerobic plate counts, E. coli, and coliforms, throughout storage at $4^{\circ}C$ and $10^{\circ}C$. Fresh-cut zucchini, cucumbers, green bell peppers, and root vegetables such as potatoes, sweet potatoes, carrots, and radishes were used. Compared to SH washing, ASC washing significantly (p<0.05) reduced microbial contamination on the fresh-cut produce and prevented browning of fresh-cut potatoes and sweet potatoes during storage. More effective inhibition of aerobic plate counts and coliforms growth was observed on fresh-cut produce treated with ASC during storage at $10^{\circ}C$. Polyphenol oxidase (PPO) activity of fresh-cut potatoes and sweet potatoes was more effectively inhibited after washing with ASC. The use of 500 mg/L ASC can provide effective antimicrobial and anti-browning treatments of fresh-cut produce, including processed root vegetables.
