Objectives: This study was performed to investigate hygienic behavior of food handlers and general population focusing on awareness of hand-washing and the microbial load of their hands. Methods: A questionnaire survey and microbiological analysis were carried out for sixty-four people each. Samples for microbiological analysis were collected through the glove-juice method from the hands, and were analyzed for the presence of aerobic plate counts, total coliform, fecal coliform, Escherichia coli, Staphylococcus aureus, and Salmonella spp. according to the Food Code of Korea. Results: In the survey, significant differences between the food handlers and general population (p < 0.01) were found in hand-washing frequency, duration, use of hand-washing agents, washing parts of hands, hand-drying method, and method of turning off water. In eight different situations among the ten particular situations in their daily life, more food handlers responded to wash their hands than general population (p < 0.05). Bacterial load on hands with general population was consistently higher than with food handlers (p < 0.05), however, percentages of positive hands of S. aureus and Salmonella spp. were not. Conclusions: Poor hand hygiene practices were indicated by the positive results for E. coli, S. aureus, and Salmonella spp. on the hands of some respondents in both groups. This study reveals that there is the need for programs or campaigns to increase hand-washing practices of both groups.

This study, after education for nursing students through texts on hand washing, PPT materials and practices, will investigated the types of the subjects' attitude toward hand washing and attempt to provide basic data needed for nursing education and nursing practice program. As the methods of this research, Q methodology was applied, and 20 sophomores in the Department of Nursing Science as P-sample from October 8, 2012 to October 15, 2012 were asked to distribute Q-sample of 9-point Q-sample distribution, and the collected data were processed with principal factor analysis method by the PC QUANL program. As a result of the research, their attitude toward hand washing was classified into 3 types. The three factors extracted all had eigenvalues greater than 1.0 and explained approximately 56.67% of the variation in responses 40.41%, 10.14% and 6.11% respectively. Type 1 was the ones with the increased number of hand washing; Type 2 was the ones who recognize the need of hand washing education; and Type 3 was the ones who dry hands after washing. In conclusion, the significance of the classification of the types of the attitude after the hand washing education is that with the development of programmes of nursing education and nursing practice, individualized intervention strategies should be differently provided.

The purpose of this study is to compare the efficiency of bacteria removal of three different types of hand washing methods. This study performed a convenient sampling of 30 volunteers in cross-over design. The study divided the 30 volunteers into three random groups. The three groups were asked to use antiseptic soap, alcohol-based hand disinfectant, and disposable wet wipes respectively. The result of the study showed that mean log reduction values after each had washing method were $-0.45({\pm}0.69)$ with antiseptic soap and water, $-1.19({\pm}0.52)$ with alcohol-based hand disinfectant and $-0.75({\pm}0.58)$ with disposable wet wipes. The difference was statistically significant when using alcohol-based hand disinfectant compared to the other two methods (p=0.000). According to this study, alcohol-based hand disinfectant was the most effective product based on bacteria removal for hand washing. Advantages of using alcohol-based hand disinfectant are that it is cost-effective and easy to buy, also eco-friendly. Therefore, to prevent infectious disease, providing alcohol-based hand disinfectant to every corner of the community will be very helpful.

The purpose of this study was to compare the efficiency of four different cleaning method of silk and to fabrics, which were excavated from the sixteenth century tombs. The four cleaning methods were hand washing in water and hand washing in solvent, washing in ultrasonic cleaner, and using of ultrasonic gun after washing in ultrasonic cleaner. The following is the result of the experiment: ㆍBoth silk and jute fabrics shrank the most after hand-wash in water. This cleaning method decreased their thickness the most but changed their strength the least. However, the color of the fabric changed the most after had-wash in water. This washing method might discolor the dyed fabric, so one must check the condition of the fabric thoroughly before washing it. ㆍThe weight and the thickness of the fabric changed little after ultrasonic cleaning. This cleaning method, therefore. is less efficient than hand-water-wash. The use of ultrasonic gun after ultrasonic wash for partial cleansing enhanced the efficiency a little. Nevertheless, this method left stain around the area where the gun was used, and the injected water could damage the fabric. ㆍThe excavated fabric became softer in the cleaning process as the dirt was washed away. In both cases of silk and jute fabrics cleaning, solvent made the fabric softer than water. Washed in solvent, the fabric did not swell. But water penetrated to the fiber during the cleaning process and made the fabric swell. When the water evaporates, the swollen fiber structure collapses and the fabric become stiff. Ultrasonic wash did not cause much change in the flexibility of the fabric, for this method does not remove the dirt as effectively as the other method.

In this study one aspect of consumer behavior in household equipment utilization was investigated the pattern, frequency, rate of washer use and their relation to the following factors a) Washer related factors : extent of the presence of desired characteristics, the evaluation of washer's intrinsic features and related household facilities. b) Psycho-social factors : attitude of energy conservation, preference & ability to wash by hand, standard of washing of the respondent homemaker. c) Socio-demographic factors : age, education level and employment status of homemaker, house-hold income, the presence of children under seven years, size of family, the presence of a paid help. The subjects of this study were 286 homemakers with washer in Seoul. Analysis methods were used to fuequency, one-way ANOVA, Gamma test, Pearson's Correlation Coefficient, t-test and multiple regression of SPSS program. The major findings are the following; 1) The pattern, frequency, rate of washe use appeared various in every household. 2) Extent of the presence of desired characteristics was very low and respondents evaluated their washer's intrinsic features moderate. 3) The pattern of washer use was affected by the evaluation of washer's intrinsic features, preference & ability to wash by hand, wife's employment and household income. The frequency of washer use was affected by family size and preference & ability to wash by hand. The rate of washer use was affected by extent of the presence of desired characteristics, the evaluation of washer's intrinsic features and preference & ability to wash by hand. Therefore, washing by hand is major substitute for washer. If more desired characteristics are added to washer, intrinsic features are improved, and maintenance costs are reduced or household income is raised, every houshold with washer will use washer more than washing by hand in washing ask so that it may gain more utility from washer.

The purpose of this study is to investigate the washing methods specified on care labels of blue jeans and to examine the appropriateness of the specification. In the study, the present condition of care labels on 100% cotton blue jeans was investigated and the consumers' washing methods of blue jeans were surveyed. Also, the shrinkage of blue jeans after washing was measured. The major results were as follows: 1. In spite of the fact that same materials of 100% cotton denim were used in all cases, washing signs on care labels showed very differently and the symbols of hand wash, using light duty detergent, no wring, drying in shade, and warm ironing with a covering cloth were demanding too high level of care for the protection of blue jeans. 2. Almost all consumers didn't follow instructions proposed on care labels because they didn't anticipate problem. In reality, most consumers washed blue jeans by machine in cold water with heavy duty detergent at standard course, dried under the sun, and didn't iron. The 40.8% of consumers didn't have problems even if they didn't follow instructions. Most problems happened after washing were shrinkage in length, but in shrinkage test after 15 times washings, it was found that there was no serious shrinkage problem. 3. For ideal care of blue jean, it is necessary for manufacturers to recognize the importance of care label and to stick correct appropriate care label. Also, consumers have to trust and follow instructions on care label.

Purpose: This study aims to investigate awareness and performance of infection control during ambulance attendant training, and to provide basic data for infection control. Methods: The subjects were 235 paramedic students who completed ambulance attendant training. There were 51 questions. The infection control dimension was divided into hand washing, personal protective equipment use, and environmental management, for each sub-dimension, awareness and performance were measured by a 4-point scale. The collected data were analyzed using SPSS statistics ver. 22.0. Results: A total of 95.3%, of the subjects completed an orientation for ambulance attendant training and 71.7% received education on infection. In all three sub-dimensions, hand- washing (p<.001), personal protective equipment use (p<.001), and environmental management (p<.001), awareness scored higher than performance. The awareness of infection control showed a significantly positive correlation (r=.394) with performance. Conclusion: In order to improve performance of infection control, education to improve awareness should be provided, and paramedics with higher performance levels in hand washing, and use of gloves and masks wearing should be assigned as training advisors.

Purpose: The study was to survey personal hygiene practice related to genito-urinary tract and menstrual hygiene management in female adolescents in order to obtain basic information for health education. Methods: With a descriptive survey design, 389 adolescents were recruited via convenience sampling in Korea. Survey instrument was the feminine and menstrual hygiene practice and perception of vaginal douching. Data were collected from a self-administered structured questionnaire. Results: Mean age of adolescents was 16.09 and menarche was at 13.21. While washing hands after urination/defecation was highly performed, wipe front to back and wash with soap and water were reported as being not well done. Twenty-eight percent reported douching habit. More positive beliefs about douching were reported by adolescents who practiced douching. Menstrual hygiene management was very appropriate with changing sanitary pads regularly with hand washing; but less performed for limiting bathing activity during menstrual periods and washing hands after activity of genito-urinary area. Conclusion: Some adolescents practiced inadequate hygiene practices especially for body cleansing during menstrual period and vaginal douching. It is important to develop and implement school health education programs on feminine and personal hygiene for adolescents to help them perform adequate health behaviors.

Objectives: This study aims to identify self-resilience factors that drive right dietary and food safety practices in middle school students. Methods: Data was collected from 438 middle school students in Daegu using a self-administered questionnaire in December, 2013. The questionnaire consisted of 81 items with the following categories: general information, self-resilience, right dietary and food safety practices. Statistical analyses to determine frequency, average, ANOVA, factor analysis, reliability analysis, and regression analysis were performed using SPSS 21. Results: The results of factor analysis indicated that self-resilience was classified into challenge, adaptability, patience and achievement needs, and right dietary practices were sub-grouped into family meals, experience of dietary life, eco-friendly, balanced food, economy and bad food control, and food safety practices consisted of management of bacteria, hand washing and eating off a plate, safety food and food purchasing. The score of right dietary and food safety practices showed significant differences by sex, grade, and school achievement (p < 0.05). The economy factor of right dietary practices was significantly affected by the management of bacteria (p < 0.001), hand washing and eating off a plate (p < 0.001), safety food (p < 0.01), food purchasing of food safety practices (p < 0.05). The challenge factor of self-resilience significantly affected family meals, experience of dietary life, balanced food, economy, bad food control, management of bacteria, hand washing and eating off a plate, and safety food (p < 0.05). The adaptability factor of self-resilience was associated with factors such as eco-friendly, balanced food, economy, bad food control, management of bacteria, hand washing and eating off a plate, and food purchasing (p < 0.05). Conclusions: This study suggests that dietary education programs for middle school students could incorporate food safety practices, and self-resilience such as challenge, adaptability, patience and achievement needs to be effective.

Background : This study aimed at identifying the effect of the standardized protocol on lowering the incidence of the ventilator associated pneumonia(VAP). Methods : The standard protocol focusing on decreasing VAP was made and applied at 5 ICUs (Medical ICU, surgical ICU, Respiratory ICU, Neonatal ICU, Pediatric ICU) in a university affiliated tertiary hospital, from April 1, 2000 to Oct 31, 2000. The protocol involved 3 parts : hand washing, the suctioning method and ventilator circuit management. All the nursing personnel received intensive education which was consisted of lecture, video film and demonstration. 176 nurses reported the performance of handwashing pre and post intervention. And randomly selected 15 nurses were observed by charge nurse and the handwashing practice was analyzed pre and post intervention. The incidence of VAP was compared with the former year incidence. Results : The self reported frequency of hand washing increased. In the direct observation of handwashing, the frequency, time, thoroughness of hand washing during 8 hours day duty was found to be improved. The frequency was increased from 1.1 time to 4.1 times; the time was improved from 1.7 seconds to 5.7 seconds and the thoroughness of the washing practice was from 0.2 times to 3.0 times respectively (p<0.001). The incidence of VAP decreased from at a rate of 15.63 number of case per 1,000 ventilator-day (April 1~August 31, 1999) to 7.23 number of case per 1,000 ventilator-days(April 1~Oct 31, 2000)(P<0.001). Conclusion : We developed the protocols which included hand washing, the suctioning method, and ventilator circuit management. Through the implementation of the protocol, the performance of hand washing improved and the VAP incidence rate in ICU was decreased.
