Objectives: This study was done to find factors related with performance of hepatitis B Vaccination among some aged persons through health belief model. Methods: A questionnaire survey was made during September 2004 toward 230 elderly persons using institutions for the elderly of Gwangju City. The relations between subjects characteristics including health belief, mass media contact, hepatitis B experience and performance of hepatitis B vaccination were tested by t test or X2 test. Multiple logistic regression analysis was done to find final significantly related variables. Results: 24.8% of the subjects were vaccinated against hepatitis B. By simple analysis of relation between performance of hepatitis B vaccination and subjects characteristics including health belief, significant variables were chosen as 6 variables including perceived susceptibility, perceived seriousness, perception of benefits, knowledge on hepatitis B, age, experience of hepatitis through family or friend. After adjusting for confounding variables by multiple logistic regression analysis, hepatitis B vaccine performance showed significantly higher rate as the perception of disease seriousness increased(OR: 1.08, 95% CI: $1.03{\sim}1.14$) and in the group contacted with TV or radio information about hepatitis compared with non-contact. The group who experienced hepatitis among family or friends showed significantly higher hepatitis B vaccination performance rate compared with non-experienced. Conclusion: These results suggested that hepatitis B vaccine performance was related with health belief including hepatitis susceptibility, disease seriousness perception, acquisition of information through TV or radio and indirect hepatitis experience from family or friends.

Purpose: This study aims at comparing nurses' knowledge, attitudes and nursing intention toward AIDS and Chronic Hepatitis B(CHB). Methods: The data were collected through self-reported questionnaires from 245 nurses between July and August, 2011. The nurses were recruited from 3 hospitals located in Seoul and Gyeonggi province. Pearson correlation coefficient and stepwise multiple regression were adopted to analyze the data. Results: Regarding AIDS, higher knowledge level was correlated with positive attitudes only(r=-.22, p<.001), which were correlated with favorable nursing intention(r=-.41, p<.001). Higher CHB knowledge level was correlated with both positive attitudes toward CHB(r=-.14, p= .030) and favorable nursing intention(r=.18, p= .004). Nursing intention toward AIDS was affected by attitudes(${\beta}$=.58, p<.001) and explained 16.6% of the variance. Both knowledge(${\beta}$=.35, p=.028) and attitudes(${\beta}$=-.49, p<.001) influenced nursing intention toward CHB and explained 19.1% of the variance. Conclusion: We need to promote nurses' positive attitudes toward AIDS to increase their nursing intention for people living with AIDS.

Hepatitis B virus (HBV) is responsible for approximately 350 million chronic infections worldwide and is a leading cause of broad-spectrum liver diseases such as hepatitis, cirrhosis and liver cancer. Although it has been well established that adaptive immunity plays a critical role in viral clearance, the pathogenetic mechanisms that cause liver damage during acute and chronic HBV infection remain largely known. This review describes our current knowledge of the immune-mediated pathogenesis of HBV infection and the role of immune cells in the liver injury during hepatitis B.

Purpose: This study was conducted to develop educational materials for preventing type B viral hepatitis infection. Prior to this study, a survey had been conducted to define the educational needs of persons with hepatitis B antigen. Method: Based on the results of the former study and a review of the literature, the content of the educational materials was confined to the transmission cycle and its prevention in type B hepatitis. A professional team that consisted of writers and producers videotaped the lectures provided by professors and instructors in a nursing school. A professional graphic designer produced the leaflet to enhance the visual effects. Results: The contents of the educational materials for type B hepatitis were composed of six parts: (1) the prevalence rate (or morbidity) of type B hepatitis antigen positive and its recent trend, (2) transformation of hepatitis. (3) transmission cycle of hepatitis infection, (4) persons who are susceptible to hepatitis and need a vaccination, (5) preventive approach hepatitis vaccination and the guideline for patients' daily lives for preventing infection and (6) questions and answers. The materials were delivered in the form of lectures, visual charts, graphics, and multi-media. Conclusion: The educational materials developed in this study may provide practical information and knowledge on strategies to prevent type B hepatitis. The educational materials may be utilized in primary health care centers or school health services.

To investigate the cognitive degree about hepatitis and hepatosis, 916 subjects are examined with query and hepatotitis B, C, E test as well as s-AST and s-ALT as liver function test. Based on results, there are 4.9% of positive hepatitis and 8.9% of hepatosis and 13.8% of liver disorder. Among positive hepatitis, there are 93.3% of type B, 42.2% of type E and 6.7% of type C, respectively. From 45% of positive hepatitis B, they carry hepatitis B and E together. The cognitive degree about positive hepatitis is 64.4%, hepatosis 8.6%. The knowledge degree from cognitive group is higher than that of noncognitive group but there is no difference from hepatosis between two groups (p<0.001). The cognitive degree of liver disorder depends on academic background (p<0.001), mother's academic background (p<0.001), job (p<0.05) and family's income (p<0.001), showing significant difference. In summary, hepatitis carrier aware quite well about liver disorder but very low from hepatosis. Accordingly, the plan to increase a cognitive degree and continuous education as well as policy support to minimize spread of disease and to protect not to be worsen disease will be needed.

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 investigate the recognition of the infection routes, symptoms and treatments of HBV by students of health-related departments so as to help students learn correct knowledge about hepatitis B and provide the basic data for establishment of oral health policies to prevent hepatitis B and improve the quality of infection management. For the subjects of this study, 666 students of health-related departments and other departments of universities in Daegu City, Gyeongbuk Province were arbitrarily chosen and given a questionnaire. Then the questionnaires collected between October 1st and 31st, 2007 were analyzed. Major findings from this study are summarized below. 1. Regarding general characteristics of the subjects, 311 were students of health-related departments and 355 were students of other departments. 55.9% of the health-related department students and 49.0% of the other department students received immunization against hepatitis. 36.0% of the health-related department students and 31.6% of the other department students had antibodies. 2. Regarding the recognition of the infection routes of HBV, the right answer "Infected through placenta" was chosen by more juniors(94.4%), sophomores(93.8%) and freshmen(74.1%) of health-related departments than other students in this order (P<0.05). The answer "Infected through sexual intercourse" was chosen by the highest percentage(75.0%) of juniors followed by freshmen(69.2%) and sophomores(31.9%) (P<0.05). 3. The percentages of health-related department students who knew that "HBV can develop into hepatic cirrhosis or liver cirrhosis were the highest among juniors(88.9%), freshmen(87.7%) and sophomores(68.8%) in this order(P<0.05). Among the other department students, the percentages of right answers to the question "Acute HBV infection shows jaundice" were the highest among juniors(75.0%), sophomores(74.8%) and freshmen(58.7%)(P<0.05).

Purpose: The aim of this study was to examine patients with Chronic Hepatitis B (CHB) and their level of knowledge of their disease, uncertainty, stress and health behaviors and to identify factors influencing their health behavior. Methods: A cross-sectional, descriptive design was used. The sample included 136 patients in a gastroenterology outpatient department at one hospital located in Seoul. The mean age of the subjects was 41 and 77.2% were male. Data were collected using a structured questionnaire from April to June 2009. The collected data were analyzed using SPSS/WIN 15.0. Results: The reported scores for knowledge of the disease, uncertainty, stress, and health behaviors were 14.43, 81.50, 26.50, 52.11, respectively. There were statistically difference between health behaviors and gender, age, marital status and antivirus treatment. A positive correlation existed between knowledge of disease and health behaviors (r=.199, p=.020). In contrast, there was a negative correlation between uncertainty and health behaviors (r=-.250, p=.003). The factors influencing health behaviors were knowledge of disease, gender, age, uncertainty, antivirus treatment, and marital status ($R^2$=.267, p<.001). Conclusion: These findings support that strategies for enhancing knowledge of disease and reducing uncertainty are needed to promote health behavior in patients with CHB.

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.

Objectives: To examine the sex-specific factors associated with being unaware of one's hepatitis B virus surface antigen (HBsAg) seropositivity status in a large, HBsAg-positive population of Koreans. Methods: In total, 1197 subjects aged 19 years or older who were HBsAg-positive according to data from the 2007-2012 Korea National Health and Nutrition Examination Survey were included. Subjects were considered unaware of their HBsAg seropositivity status if they answered that they had no knowledge of being previously infected by the hepatitis B virus (HBV) or diagnosed with HBV hepatitis. Multivariate Poisson regression models with robust variance estimate were used to assess the significance of the variables using weighted frequencies. Results: The majority (77.8%) of HbsAg-positive Korean adults (females, 81.9%; males, 74.6%) were unaware of their HBsAg seropositivity status. We found that sex (female: prevalence ratio [PR] 1.19), household income (low: PR, 1.15), marital status (never married: PR, 1.18), self-rated health (moderate: PR, 1.14; good: PR, 1.12), and alcohol use (at least 2-3 times/wk: PR, 1.21) were associated with being unaware. In females, age (50 to 59 years: PR, 1.29; ${\geq}70$ years: PR, 1.30), household income (low: PR, 1.37; middle-low: PR, 1.24), and marital status (never married: PR, 1.33) were associated with being unaware. In males, self-rated health (moderate: PR, 1.14; good: PR, 1.21) and alcohol use (at least 2-3 times/wk: PR, 1.21) were associated with being unaware. Conclusions: Factors related to the socioeconomic status of females and the health-related behaviors of males were found to be associated with being unaware of one's HBsAg seropositivity status.
