To show the recognition of hand-sanitizer, we studied the answers of research questions where we got from the northern part of Seoul and Kyunggi Province. We had categorized two groups both industry-related people who work in restaurants, hygiene service shops, whole sales, government organizations, PC shops, factory-department stores and non industry-related people who work in schools, general offices for this study. 1. Hand sanitation level: Over 60% people washed hands 6 times a day. The group using water and soap was much bigger than the group using water for washing hands. For drying, people preferred wipe tissue, towels, clothes, non drying in that order. 2. Recognition of hand sanitizer and its usage experience: Most people(66.5%) did not know what hand sanitizer is, but they have positive attitude if they use this machine. 3. Place of hand sanitizer: The proper places to install were such public places as hospitals, restrooms, and restaurants. The fifties-group was the most frequently hand washing generation with over 9 times a day. 4. Comparison of recognition for hand-sanitizer by male and female: There were different results in each evaluation item by either male or female. The frequency and method of hand washing showed high in males, while females observed hand sanitization, installation requirements, installation areas, home installation, etc more than anything else.

Hand-washing is one of the most important factors in infection control and in preventing cross-contamination. The objective of this study was to investigate female university students' awareness of hand-washing, their hand washing practices, and the difference between their awareness and practices. A self-administered questionnaire survey and direct observation in restrooms were separately carried out in a university campus and over four weeks' period. A total of 97.4% of the survey respondents claimed to wash their hands after using toilet, and 98.2% of the observed students actually did so according to the unnoticed observational study. However, only 6.3% of the students who washed their hands in the direct observation washed for more than 10 seconds, although 46.4% of respondents in the survey reported that they usually wash their hands for more than 10 seconds. Among the observed students who washed their hands, only 0.9% used soap, and 0.9% washed four parts of their hands. Paper towel was the most common hand-drying method in the direct observation and also in the survey. Significant differences were found in duration, use of soap, part of washing, and hand-drying method between the questionnaire survey and the direct observation (p<0.05). This study indicates that there is a noticeable difference between the awareness of hand-washing and hand-washing practices among female university students. Further research should examine hand-washing practices of female university students in restrooms outside the university campus.

Hand-washing has been recognized as a critical factor in controlling infection and cross-contamination. This study was performed to investigate hygienic behavior of male university students focusing on awareness of hand-washing, their hand washing practices, and the difference between their awareness and practices. Both a self-administered questionnaire survey and a separate direct observation in restrooms were carried out at a university campus over a four week period. In the survey, 93.6% of the responded students claimed to wash their hands after using toilet. However, just 16.9% of the observed students actually did so, according to a separate and unnoticed observational study. Among the observed students who washed their hands, 25.0% of them used soap, only 5.0% of them washed four parts of their hands, and 15.0% of them washed their hands for more than 10 seconds. Paper towel was the most common hand drying method in the direct observation and also in the survey. Significant differences between the questionnaire survey and the direct observation (p<0.0l) were found in hand-washing practices, duration of hand-washing, using soap, washing parts of the hand, and hand-drying method after using the toilet. This study indicates that there is a remarkable difference between the male university students' awareness of hand-washing and their hand-washing practices. This study reveals that there is the need for programs or campaigns to increase hand-washing practices of male university students.

This study is therefore aimed at measuring the surface dose rate and the spatial dose rate in and outside the radionuclide facility in order to ensure safety of the patients, radiation workers and family care-givers in their use of such equipment and to provide a basic framework for further research on radiation protection. The study was conducted at 4 restrooms in and outside the radionuclide facility of a general hospital in Incheon between May 1 and July 31, 2014. During the study period, the spatial contamination dose rate and the surface contamination dose rate before and after radiation use were measured at the 4 places-thyroid therapy room, PET center, gamma camera room, and outpatient department. According to the restroom use survey by hospitals, restrooms in the radionuclide facility were used not only by patients but also by family care-givers and some of radiation workers. The highest cumulative spatial radiation dose rate was 8.86 mSv/hr at camera room restroom, followed by 7.31 mSv/hr at radioactive iodine therapy room restroom, 2.29 mSv/hr at PET center restroom, and 0.26 mSv/hr at outpatient department restroom, respectively. The surface radiation dose rate measured before and after radiation use was the highest at toilets, which are in direct contact with patient's excretion, followed by the center and the entrance of restrooms. Unsealed radioactive sources used in nuclear medicine are relatively safe due to short half lives and low energy. A patient who received those radioactive sources, however, may become a mobile radioactive source and contaminate areas the patient contacts-camera room, sedation room, and restroom-through secretion and excretion. Therefore, patients administered radionuclides should be advised to drink sufficient amounts of water to efficiently minimize radiation exposure to others by reducing the biological half-life, and members of the public-family care-givers, pregnant women, and children-be as far away from the patients until the dose remains below the permitted dose limit.

This study examined the effectiveness of and satisfaction of visitors with the Environmental Improvement Project on national parks' trail entry areas. A survey was conducted to improve the proposal framework based on the data. Data for the study were obtained from 6400 respondents who used 28 national park offices at 32 national park trail entry areas. The field research was collected in 3200 surveys, divided between pre- and post-implementation of the Environmental Improvement Project. The study variables consisted of socio-demographics, visitors' perceptions on the environmental improvement of trail entries, effects of the environmental improvement, and visitor satisfaction. Several important results were found. First, the environment of trail entries has a significant impact on the formation of images and user satisfaction of national parks. Second, the influence of the trail entry improvement showed that 71.8% of visitors rated the trail entry as environmentally friendly after the Environmental Improvement Project, compared to 48.5% of visitors rated the trail entry as environmentally friendly before the Environmental Improvement Project. The findings indicated that a top priority of environmental improvement of the trail entries needs to be the installation of convenience facilities such as rest areas, restrooms, and direction boards (pre: 34.5%, post: 32.6%). Third, functionality and the other nine variables were shown to enhance the effect of the environmental improvement of the trail entries at the 1% statistical significance level. Finally, results indicated that the overall satisfaction of the visitors with the park was significantly higher after the environmental improvement (t-value=25.741, p=.000), showing the satisfaction score was higher after the environmental improvement (pre: 3.51, post: 4.12), with a statistically significant difference at the 1 % level. This study helps to understand trail entries, which have influenced the image of the national park and satisfaction. These findings can be utilized to manage and design a national park as a public space.

Using small cameras such as smartphones, criminals shoot secretly in public restrooms and women's changing rooms. And Revenge porn is also increasing. As a result social damage is increasing. Tumblr is an overseas service and it is very difficult to work with Tumbler on international legal cooperation and deletions. Thus In order to block the distribution of videos, victims must find and report the video URL themselves. But it's hard for victims who lack IT expertise to proceed those procedure. In this study, we automatically collect the URL of stored information and hash values of the images from API permlink of Tumbler blog. It is then saved as a document file with and presented to the victim. Through these technical methods, we can help victims report violations easily and quickly.

This study was performed to investigate awareness of hand washing, hand washing behavior, and the levels of indicator microorganisms on hands of food handlers who work in the food court and cafeteria of a university campus. The three methods used were questionnaire survey by interview, direct observation in restrooms, and microbiological examination according to the Food Code of Korea. A positive attitude toward hand washing compliance was reported by the responded food handlers; however, improper hand washing and poor hand hygiene of the food handlers were recognized by the unnoticed direct observation. Significant differences were found between the questionnaire survey and the direct observation (p < 0.05) in hand washing compliance after using the toilet, duration of hand washing, use of hand washing agent, washing different parts of the hands, hand-drying method, temperature of water, and method of turning off the water. Samples taken from their hands before work showed higher level of standard plate count, total and fecal coliforms, and Escherichia coli than those taken after washing with water. After washing hands with antiseptic liquid soap, the bacterial populations including Staphylococcus aureus on hands were dramatically reduced. This study indicates that there is a remarkable difference between the food handlers' awareness of hand washing and their hand washing behavior. Poor hand washing compliance and hand hygiene were indicated by the positive results of total and fecal coliforms, E. coli, and S. aureus on hands of some food handlers. The findings of this study suggest that the hand hygiene of the food handlers need to be improved. More training/education on hand washing and hand hygiene of the food handlers should be necessary.

The purpose of this study was to examine the state of convenience facilities for the disabled in dental institutions in an effort to provide some information on the improvement of the accessibility of disabled people to dental institutions. A survey was conducted on the licensed dental institutions in the city of Cheongju, North Chungcheong Province, from March to April, 2011. The findings of the study were as follows. The dental offices were the majority of the dental institutions investigated, and for the establishment of the dental institutions. Some of the offices were established before 1990, and some were established in 2011. The time period of establishment varied within the offices. As for the location of the dental institutions within the buildings, they were mostly on the second or third floor. Regarding the convenience facilities for the disabled, the most installed convenience facilities were boardwalks and elevators, and the least installed ones were parking lots and restrooms for the disabled. The hospitals and public dental centers were equipped with all the convenience facilities investigated in this study. Overall, the dental institutions that were established in and after 2006 were equipped with more convenience facilities than the dental institutions that were established before 1990. And the dental clinics that were on the third or higher floor were more equipped with elevators and outdoor slope ways than those that were on the first or second floor. Therefore the revision of the law is required to urge even the primary dental institutions to compulsorily install the convenience facilities. The findings of the study are expected to make a contribution to the improvement of the accessibility of disabled people to dental institutions.
