The purpose of this study was to survey the knowledge and awareness of dental hygienists and dental hygiene students about hepatitis B in an attempt to lay the solid foundation for the prevention of hepatitis B and infection control, as dental hygienists were highly likely to be exposed to HBV during job performance. The findings of the study were as follows: 1. 32.5% of the dental hygienists and 15.6% of the dental hygiene students were aware of their own HBsAg and HBsAb states. The dental hygienists who were cognizant of the states statistically significantly outnumbered the dental hygiene students who were (p=.000). 2. As for vaccination against hepatitis B, 71.8% of the dental hygienists and 47.3 % of the dental hygiene students were inoculated against it. The dental hygienists who were vaccinated against it outnumbered the dental hygiene students who were, and the disparity between the two was statistically significant (p=.000). 3. In the event of those who were vaccinated against hepatitis B, the dental hygienists were better cognizant than the dental hygiene students of the right time for the vaccination, required vaccination frequency (three times) and confirmation of the formation of hepatitis B antibody (p=.000). 4. Regarding awareness of hepatitis B infection route, the dental hygienists knew significantly better than the dental hygiene students that hepatitis B might be infected via blood (p=.030), sexual relations (p=.000), contaminated needle sticks (p=.000), mothers with hepatitis B positive during delivery (p=.000), toothbrushes/razors (p=.000) and exchange of drinking cups (p=.000). 5. As to the relationship between health status and knowledge on hepatitis B infection route, the respondents who were in bad shape had the best knowledge about that, followed by those in an average state of health and healthy respondents. And the dental hygienists had a significantly better knowledge than the dental hygiene students (p=.001). 6. Just a small number of the dental hygienists and students knew about the hepatitis B-related past experiences of their families, and the gap between the two was insignificant.

The purpose of this study was to identify the effect of structured patient education on knowledge of Hepatitis B type and behavior about self care in chronic hepatitis B patients, and to fine the strategy to promote their self care behavior. The research design was quasi-experiment research. The study method had been done by investigating the experimental group and control group through the questionnaire on 50 patients who had been out patient medicine department in U university hospital in Ulsan from september 1st 1997 to the end of October, 1997. The analysis of the collected material had been done for the homogeneity test in which general characterics of experimental group and control group had been tested by $x^2-test$ and the homogeneity test of the knowledge of hepatitis B type and self care behavior before by t-test. To test the hypothesis the t-test had been given for the difference of the knowledge of hepatitis B type and self care behavior between the two groups and the correlation between knowledge of hepatitis B type and self care behavior performance had been tested by Pearson's correlation coefficient. The results as follows : 1. The 1st hypothesis 'The experimental group which received the structured education should be higher in the knowledge of hepatitis B type than the control group' was supported(t=-6.25, P=.000). 2. The 2nd hypothesis 'The experimental group which received the structured education whould be higher in the self care behavior performance than the control group' was supported(t=-5.15, P=.000). 3. The 3rd hypothesis 'The higher the knowledge of hepatitis B type in the patient the higher the self care behavior performance degree' was supported(r=.492, P=.001). In conclusion, the patients who received the structured education showed the increase in the degree of knowledge of hepatitis B type and self care behavior performance. so the structured education had been judged the nursing intervention had been prerequisite in increasing knowledge of hepatitis B type and self care behavior performance of the chronic hepatitis B patients.

Purpose: The purpose of this study was to identify awareness and knowledge about hepatitis B virus (HBV) infection among North Korean immigrants who had resided in South Korea. Methods: This was a cross-sectional, community based study. Data were collected from a convenience sample of 198 North Korean immigrants aged 18 years old through 65 years old among those who had attended community centers, local churches, and gathering places in four cities. The questionnaire included 15 items about participants' knowledge on HBV infection and its consequences, mode of transmission, and preventive measures. Results: The mean score of HBV knowledge was $6.3{\pm}3.8$ (range 0~15). The items that over 60% of the respondents checked correct answer regarding knowledge about HBV were 'There is blood screening for hepatitis B infection', 'Hepatitis B can be transmitted through sharing needles with infected person'. Multivariate analysis showed that received education for the prevention of HBV infection and disease morbidity were significantly associated with the knowledge of HBV infection. Overall, approximately 11% of total variability in the knowledge of HBV infection could be explained by the 2 variables in this model ($R^2=.109$, p<.001). Conclusion: The results showed that North Korean immigrants need more education on HBV infection and prevention to improve their knowledge about HBV.

Purpose: The purpose of this study is to examine the impacts of infection control education on dental hygienists' perceptions for hepatitis B and their behaviors. Materials and methods: Study participants were chosen by random selection among dental hygienists working in Seoul, Korea. A total of 150 questionnaires were sent out for the survey from April 2013 to May 2013, of which 140-excluding incomplete responses-were used for the study. Chi-square tests and t-tests were used (SPSS 19.0), and post-hoc analysis was performed as well. The maximum significance level was 0.05. Results: Average 1.53 times infection control education was taken, but dental hygienists' perceptions for hepatitis B and their behaviors did not show statistical differences whether the education was done or not. Practices to prevent infection showed differences depending on categories, especially disinfection and sterilization were well performed by educated group. The most common reasons for not taking the education and noncompliance with infection prevention guidelines are lack of time and opportunity due to busy schedule. Conclusion: 1. The more highly educated, the greater number of patients per day, and the greater size of hospitals, the better infection control education was conducted. 2. Although hepatitis B is one of the most common chronic liver diseases in Korea, no significant correlation between perceptions of hepatitis B and infection control education was found. 3. Dental hygienists who received infection control education performed more efficient practices for protection against infections than those who did not.

This study aimed to provide basic information on dental hygienists' practicing the prevention of infections by figuring out their actual conditions in dental clinics. The subjects of the study were the dental hygienists who participated in the continuing medical education of Incheon & Gyeonggi-do association and Seoul city association in October and November 2005 and the self-administered surveys were used for the prevention of infections. The results were as below. 1. In terms of education experiences of infection prevention, those who answered "there were" were 72 persons (42.9%) and those who followed the educational route for infection prevention were "through the in-house education from the hospital" and they were 42 persons (58%), which were highest. 2. In terms of the injury experiences, those who answered "there were" were 147 persons (87.5%) and the number of annual injury out of 147 persons with injury experiences was 7.7 time. For the tools that were damaged, 125 persons (75%) damaged the "explorer," which was highest. 3. For the experiences of being infected with contagious diseases, those who answered "there were" were 6 persons (3.6%) and there were four persons for "hepatitis B", one person for "rubella" and one person for "TB." 4. The questions with high practice scores were as in the following: "2. I wash my hands after conducting medical examinations (1.86 points)," "7. I always close the lid of a shot of Novocain after doing local anesthesia (1.86 points)" and "20. I separate and collect the wastes and give them to those who treat accumulated materials (1.85 points)". Meanwhile, the questions with low practice scores were as below: "16. I change my medical gowns (doctor wears) once a day (0.24 point)" and "I wash my medical gowns every time after examining patients with contagious diseases (0.52 points)." 5. The question with high knowledge was as below: "1. The contagion during the dental treatment is determined by source of infection, infection methods, infection routes and the host that is prone to infection (0.95 point)" and the question with the lowest knowledge was "5. HBV(hepatitis B) is destroyed after adding 95oC of heat for more than 5 minutes (0.27 points)." 6. The question with the highest organization-related factors was "I am always ready to use a mask, gloves, etc. if necessary" (0.89 points)" and the question with the lowest score was "There is a guideline that I can refer when I am exposed to dangerous situations related to the contagion in my workplace (0.33 point)." 7. In terms of the equipment conditions of protectors in medical environments, 168 persons for (disposable) mask (100%), 167 persons for disposable gloves (Latex) (99.4%), which meant that most of them were equipped with them.

The purpose of this was to evaluate the level of knowledge about Hepatitis B and AIDS among dental hygiene students at six dental hygiene educational programs in nationwide, compare the findings to those of Song's study. 1703 dental hygiene students surveyed by mail and answered a questionnaire, using the questionnaire used developed by DiClemente el al., on Hepatitis B vaccination, antibody production, experience of unintentional needle stick injuries, experience of surgical operation and blood transfusion, personal risk factors for HBV and HIV, management of HBV and HIV postexposure management et al. The data indicated that dental hygiene students (79.0%) in this study had more HIV vaccination than dental hygiene(74.3%) in Song's study. As for recognition of antibody production after Hepatitis B vaccination, only 34.6% of respondents answered they knew having antibody production and 95% of respondents knew not having antibody production. Over one-half of the respondents (55%) answered they didn't even recognize having antibody production. 52.3 percent of dental hygiene students experienced unintentional needle stick injuries. The findings on the knowledge about Hepatitis B and AIDS were that dental hygienists (76.5 points) received higher mean score than those of dental hygiene students (71.0 points) and that the distribution of right answer rate also showed wider range in dental hygiene students (27.7~97.5%) than those of dental hygienist (41.2~99.5%). There were no statistical differences among dental hygiene education programs. Finding of this study support that the curriculum of dental hygiene program should include instruction on sources and methods of transmission of infectious diseases, risk of virus transmission in the workplace and principles of infection control. Furthermore, infection-control practices should be utilized routinely and their application to dental personnel, management of HBV and HIV postexposure management. Furthermore, for preventing the further spread of infectious diseases (HBV, HIV and AIDS${\cdots}$) caused by bloodborne viruses, imposing an obligation rather than recommendation on Hepatitis B vaccination to all dental personnel and routinely utilizing infection-control guidelines for all dental patients in dental practices (include dental educational programs) should be accomplished by coordination the government agency.
