Objectives: The purpose of this study was to investigate the relationship between toothbrushing and hand washing according to health education experience in middle school students. Methods: The subjects were 480 students of four middle schools in Y region. This is a cross sectional study and the study instrument was adapted from the knowledge, attitude and practice of hand washing and toothbrushing in elementary school students by Jung. Cronbach's alpha was 0.87 in the study. The questionnaire consisted of 5 questions of the general characteristics of the subjects, 5 questions of hand washing knowledge, 3 questions of hand washing behavior, 3 questions of health education experience. Toothbrushing questionnaire consisted of 10 questions of knowledge, 5 questions of behavior, 5 questions of health education experience, and 5 questions of dental health care facilities within schools. Data were analyzed by PASW 20.0 program. Results: Toothbrushing more than three times a day accounted for 76.8%. Those who receiving health education in elementary school accounted for 41.5% and those who had not accounted for 58.5%. Health education experience(75.8%) led to toothbrushing after meal(p<0.05). Those who receiving health education in elementary schools had 1.76 times of toothbrushing after meal than those who had not(p<0.01). Conclusions: Middle school students receiving health education had a tendency to do toothbrushing and hand washing frequently.

Background: The purpose of this study was to identify the connection between handwashing and toothbrushing, focusing on eating habits, and to verify whether eating habits can be used as an action cue for forming health habits. Methods: This was a cross-sectional study using secondary data from the 2019 community health survey. The participants included 229,099 adults aged 19 years or older, representative of the South Korean people. We employed two dependent variables: one was washing hands, and the other was brushing teeth. Eating habits was a major independent variable. Socioeconomic variables, such as age, gender, income, occupation, economic activity, education, and residence were adjusted as confounders. Multivariate logistic regression was performed to calculate adjusted odds ratio and 95% confidence intervals. Results: Most of the participants had good health behaviors: those who wash their hands and brush their teeth were each approximately 80%. Our finding indicated that brushing teeth and washing hands can be connected with eating habits. After adjusting for confounders, it was found that people who wash their hands before meals (compared to those who did not wash their hands before meals) had a higher toothbrushing rate after meals (i.e., socioeconomic status) (Adjusted Odds Ratio: 2.0, Confidence Intervals: 1.9 to 2.1). Conclusion: Those who practice either washing hands before meals or brushing teeth after meals were found to have a connection between washing hands and brushing teeth based on the results of practicing other health behaviors. This implies that eating habits can be connected as a behavior cue to promote health habits, such as washing hands before meals and brushing teeth after meals.
Purpose: This study investigated hand-washing practice among community-dwelling older adults during the coronavirus disease 2019 (COVID-19) pandemic and aimed to identify the impact of COVID-19-related concerns and depression on hand-washing practice. Methods: This was a secondary analysis of data extracted from the 2020 Community Health Survey. The primary data were collected through self-reporting from August 10 to September 8, 2020 in a cross-sectional study. The subjects comprised of 1,350 adults aged 65 or older living in Jeju Province who participated in the 2020 Community Health Survey. Results: The factors affecting hand-washing practice among older adults were male older adults (β = -.18, p < .001), age (β = -.07, p = .001), no education (β = -.20, p < .001) and elementary, middle, and high school graduation (β = -.15, p < .001) compared to a college or higher education, poor health perception (β = -.13, p < .001), COVID-19-related concerns (β = .08, p = .005), and depression (β = -.07, p = .001). To summarize, the factors negatively affecting hand-washing practice included male gender, lower education level, poor health perception, and depression. In contrast, factors positively associated with hand-washing practice included COVID-19-related concerns. Conclusion: These findings show the importance of considering these multifaceted determinants when designing targeted interventions and educational programs to promote hand-washing among older adults. Additionally, based on the relationship between hand-washing practice and COVID-19-related concerns and depression, interventions that can alleviate mental problems along with providing proper education are required.

Objectives : This study was designed to evaluate the pesticide residue of herb medicine through high density ozone water cleaning system. Materials and Methods : We purchased ginseng(Panax ginseng) on market and sprayed pesticides (Diazinon) on ginseng. We analyzed pesticide residue according to washing methods(untreated, ozone water cleaning, ultrasonic cleaning, Water cleaning). As a result of each washing methods, in ozone water cleaning method pesticide residue was much less remained than in Ultrasonic Cleaning method and water cleaning method. Conclusions : High density ozone water cleaning is the best method for removing pesticides of herbal medicine.
We sought to improve the methods for washing fresh raw ginseng. The quality of ginseng surface-washed by different methods was evaluated during storage at 10C and $20^{\circ}C$. The raw ginseng surface-washing method was a full-cone spray-type procedure using water and air. The water for decontamination had an electrolysis value of 80 ppm, also known as electrolysis water $2^{\circ}C$ water and water containing 5 ppm chlorine dioxide, were also used for decontamination. The Hunter color (${\Delta}E$) of ginseng washed with water withan electrolysis value of 80 ppm, or water with 5 ppm chlorine dioxide, was greater than that seen after other washing methods were used. The weight loss after washing with 5 ppm chlorine dioxide water was similar to that seen after washing with $2^{\circ}C$ water or 80 ppm electrolysis water. Reductions in total microorganism levels, and counts of yeasts and molds, assayed 10 days after washing with 5 ppm chlorine dioxide water were greater than seen after use of other sterilization methods. Quality maintenance on storage, at both 10C and 20C, after washing with 80 ppm electrolysis water, was better than that noted after other sterilization methods. The moisture content of washed ginseng was similar under all storage conditions tested.
This review investigated theoretical principals and practical application examples on recirculation system of soil washing-wastewater treatment-treated water recycling. As for technologies which have attempted to remediating metals-contaminated soil in and around country, there are reactive barriers, encapsulation, solidification/stabilization, soil washing, and phytoremediation. Among those, in particular, this review covers soil washing technology which physicochemically removes contaminants from soils. The major drawbacks of this technology are to generate a large amount of wastewater which contains contaminants complexed with ligands of washing solution and needs additional treatment process. To solve these problems, many chemical treatment methods have been developed as follows: precipitation/coprecipitation, membrane filtration, adsorption treatment, ion exchange, and electrokinetic treatment. In the last part of the review, recent research and field application cases on soil washing wastewater treatment and recycling were introduced. Based on these integrated technologies, it could be achieved to solve the problem of soil washing wastewater and to enhance cost effective process by reducing total water resources use in soil washing process.
As the eye irritant test of lens washing agent, ReNu$^{TM}$ was analysed using Draize methods (1959) according to KFDA Guidelines. In addition, to test the potential toxicity of test articles the ratio of inflammatory cells and non-inflammatory epitheloid cells were also observed using smear cytology methods against ocular discharge. At test, the histopathological changes on the cornea, iris, retina and sclera were also observed in all animals. Slight irritancy of the cornea and conjunctiva were observed at 1, 2 and 3 days after dropping in non-washing group. The Mean Index of Ocular Irritation(MIOI) of these points are detected as 4.17, 3.00 and 1.33, respectively. In washing group, slight irritancy of the cornea and conjunctiva were observed at 1 and 2 days after dropping with MIOI as 0.67 and 1.33, respectively. Therefore, ReNu$^{TM}$ was considered as non-irritating materials because the MIOI is detected below 5.00 throughout the whole experimental periods in both washing and non-washing groups. The Index of Acute Ocular Irritation(IAOI) is also detected as 4.17(1 day after dropping). Except of the somewhat increase trend of the inflammatory cell ratios in ocular discharge at 1 day after dropping of non-washing group, but significances are not detected, on the other hand, no meaningful changes on smear cytology of ocular discharges are observed in this study. In addition, no abnormal histopathological changes on the cornea, iris, retina and sclera were also not detected in ReNu$^{TM}$ dropping group compared to that of non-treated control eyes.
The eye irritant test of lens washing agent, CLIWELL$^{TM}$ was conducted using Draize methods according to KFDA Guidelines. In addition, to test the potential toxicity of test articles, the ratio of inflammatory cells and non-inflammatory epitheloid cells was also observed using smear cytology methods against ocular discharge. At sacrifice, the histopathological changes on Cornea, Iris, Retina and Sclera were also observed in all animals. Slight irritancy of cornea and conjunctiva was observed at 1, 2 and 3 days after dropping in non-washing group. The MIOI of these points are detected as 4.50, 1.67 and 0.67, respectively. In washing group, slight irritancy of cornea and conjunctiva were observed at 1 and 2 days after dropping with MIOI as 0.67, respectively. Therefore, CLIWELL$^{TM}$ was considered as non-irritating materials because the MIOI is detected below 5.00 throughout the whole experimental periods in both washing and non-washing groups and the IAOI was also detected as 4.50. Except for significant increase of the inflammatory cell ratios in ocular discharge at 1 day after dropping of non-washing group compared to that non-treated intact eyes, no meaningful changes on smear cytology of ocular discharges are observed in this study. In addition, no abnormal histopathological changes on the cornea, iris, retina and sclera were also detected in CLIWELL$^{TM}$ dropping group compared to that of non-treated intact eyes.
Objectives : This study is designed to identify the need for an efficient infection control plan in the curriculum of Dept. of Dental Hygiene and encourage dental hygienists to be more attentive to infection control by analyzing their personal protective measures, hand-washing frequency and other factors relating to infection control. Methods : A survey was conducted of 471 dental hygienists in general hospitals, dental clinics and dental hospitals in City of Busan and Gyeongsangnam-do from December 20, 2009 to February 21, 2010. Results : 1. Among those who worked for more than 11 years, personal protection (3.79) and hand-washing frequency (3.90) factors were rated high (p<0.05). 2. When surveyed by workplace, personal protection was high in general hospitals (3.75) while hand-washing frequency was high in dental clinics (3.74). 3. Among those who received infection control education more than three times, personal protection (4.07) and hand-washing frequency (3.80) were high (p<0.05). 4. Personal protection-related factors were general hospital workers, necessity of infection control education and awareness on infectious disease (p<0.05), while factors associated with hand-washing frequency were number of patients per day, whether or not infection control-related class is given at school, necessity of infection control education and awareness on infectious disease (p<0.05). Conclusions : To enhance awareness of infection control, it may be necessary to addan infection control-related class to the school curriculum and provide the necessity of conducting continuous and systematic infection control education through newly entering staff training and education of dental practitioners.

Purpose: Hand washing has received renewed emphasis in recent years as Swine flu epidemic threaten health of public. This study aimed to describe measures used to prevent new types of influenza (NTI); describe hand washing frequency; and analyze the relationship of hand washing to locus of control, uncertainty, and state anxiety. Methods: One hundred thirty three adults participate in the questionnaire survey in which participants indicated measures they used to prevent NTI, frequency of handwashing for the prevention of NTI. They also responded to questions related to locus of control, uncertainty and state anxiety. Data were analyzed using descriptive statistics, Pearson correlation and multiple regression. Results: A majority (66.9%) of the participants indicated that handwashing was an important measure to prevent NTI. Importance of hand-washing was related the highest among the measures they used and it was significantly related to participants who had high score in internal locus of control. Other significant factor to the hand-washing behavior was state anxiety, which explained 6.9% of the frequency. Conclusion: According to the results of this study, majority of participants indicated that handwashing was one of the most important measures to prevent NTI. Nurses need to continue educating public the importance of handwashing and pay attention to personal characteristics such as internal locus of control and anxiety to promote hand-washing.
