This study used the health belief model of college students to investigate the not with regards to their health status awareness, health management, and their health beliefs. Logistic regression analysis showed a significantly high odds ratio between intent of hepatitis B vaccination and gender, The trend for receiving a hepatitis B vaccination was highest in groups with awareness of the high susceptibility and seriousness of hepatitis B, groups with awareness of the low barrier, and women as opposed to men. Therefore future research is needed regarding appropriate promotions of the seriousness and benefits of hepatitis B vaccinations as well as the development of a integrated health education mediation program and effect evaluation.

The purpose of this study was to provide basic data for related researches on knowledge, attitude, and health belief related to hepatitis B and development of a preventive education program for the rise of its vaccination on college students of dental hygienics and dental laboratory technology majors. The questionnaires were distributed to a total of 252 students from April 26 to 30, 2018. The mean knowledge score of hepatitis B was 11.60 out of 20.0. The mean scores for their attitude and health belief on hepatitis B were 3.51 and 3.10 out of 4.0, respectively. Only 38.9% of the subjects were vaccinated and 53.6% of them were not educated. The factors affecting the vaccination were clinical training experience and prevention education. It is essential to provide healthcare education on knowledge, attitude, and health belief related to hepatitis B and to develop a convergent education program because the students may be manpower for healthcare institutions in the future.

The purpose of this study was to investigate the differences in health belief related to vaccination among dental hygiene students, identify the factors affecting hepatitis B vaccination, and provide basic data for health education concerning hepatitis B prevention. Hepatitis B vaccination was positively correlated (r=0.179, p=0.003) with seriousness of believing that hepatitis B would affect psychological, physical, and social activities and negative correlation (r=-0.183, p=0.002) was also found between perceived barriers related to hepatitis B. As for the factors affecting hepatitis B vaccination, juniors were 0.39 times (95% confidence interval [CI]=0.21, 0.71) more likely to have it affected than seniors and those who were more serious, and who had greater barriers were more likely to have it affected-1.80 times (95% CI=1.29, 2.52), 0.61 times (95% CI=0.41, 0.90) respectively (p<0.05). It is therefore urgent to develop a program within a curriculum that can begin with freshmen along with specific education with the objective of obliging dental hygiene students to receive hepatitis B vaccination. It is also necessary to provide consecutive sessions of education rather than one-time education and to develop a specific plan for obligatory hepatitis B vaccination through correct and thorough education.

Objectives: This study aimed to identify the vaccination coverage for hepatitis B among aged 19 or older, and at the same time to determine the reasons for vaccination or non-vaccination. Methods: The survey was conducted through a Mixed-Mode Random Digit Dialing Survey (RDD) method. The survey included hepatitis B vaccination status, reasons of vaccination and non-vaccination, sources of information on vaccination, and other related factors. Results: The vaccination coverage for hepatitis B among adults 19 years of age and older were 38.0%, 32.5%, and 26.9% for the first, second, and third doses. A related factors with high rate of hepatitis B vaccination was women, younger than 65 years of age, rural residents, having a job, highly educated, health insurance subscribers, living with spouse, family members living together. In addition, the vaccination rate was higher in those who was aware of the states recommended adult vaccination, were explained by a doctor about the need for adult vaccination, kept their vaccination records, and recognized that it helped prevent infectious diseases, and had seen promotional materials. Conclusions: In the future, it is necessary to check the antibody retention rate along with the hepatitis B vaccination coverage of adults on a regular basis. In addition, in order to accurately and quickly identify the hepatitis B vaccination coverage, it is necessary to prepare a plan to improve the computerized registration rate to manage adult vaccination records.

Purpose : To evaluate the immunogenicity of hepatitis B vaccine among very low birth weight infants(VLBWI) who were vaccinated at 0, 1, 6 months of chronological age and to determine the factors associated with antibody formations. Methods : A total of 243 VLBWI admitted to Seoul and Gangneung Asan Medical Center neonatal intensive care units from 1997 to 2004 were included. Of 243, 13 infants were born to HBs Ag positive mother. All infants were given DNA recombinant vaccine at 0, 1, and 6 months of chronological age. Infants born to HBs Ag positive mothers received hepatitis B immunoglobulin at birth and a total of 4 doses of vaccinations. An antibody level over 10 mIU/mL, tested at 3-4 months after last vaccination, was regarded as a positive seroconversion. Results : The seroconversion rates were 84.4 percent and 84.5 percent for VLBWI and extremely low birth weight infants(ELBWI), respectively. Of 28 seronegative infants who were given revaccinations, 60.7 percent seroconverted, resulting in 95.3 percent, 97.5 percent seroconversion rates for VLBWI and ELBWI, respectively. 76.9 percent of infants born to HBsAg positive mothers seroconverted and none became hepatitis B carriers. Factors such as gestational age, sex, various neonatal illness, and kinds of vaccinations did not influence the formation of the hepatits B antibody, however, the higher the weight at time of first vacciation yielded better seroconversion rate. Conclusion : Revaccination of seronegative VLBWI after 3 doses of hepatitis B vaccinaton is very effective. Therefore, testing the immune status after the hepatitis B vaccination, a practice not routinely done, is highly recommended.

Hepatitis B virus(HBV) infection is one of the major health problems in Korea and HBsAg positive rate was known to be about $5\sim15%$ in general population. This study was conducted to identify the positive rates of serum HBsAg and anti-HBs among community population regarded as having hish HBV vaccination rate than in previous decade, using EIA(Enzyme immunoassay) method, in Seo-Gu, Taegu, Korea. The study subjects were 1,160 who visited Seo-Gu Health Center for check-up serologic markers of hepatitis 3. The data were obtained from the serologic test for hepatitis markers and questionnaire survey was conducted to obtain the general characteristics, vaccination history, past history of hepatitis and other liver disease, and exposure history to risk factors of hepatitis of the study subjects. The positive rates of HBsAg and anti-HBs were 5.2% and 62.4% respectively. The positive rates of HBsAg for male and female were 6.6% and 4.3% respectively. The age was divided into two groups as group I (less than 15 years old), group II (more than 16 years old) according to the hypothesis that these two groups might be different in HBV vaccination rate. HBV vaccination rates for group I and II were 83.1% and 52.3%. The positive rates of HBsAg for group I and II were 2.6% and 6.5%. The positive rates of HBsAg for the vaccinated people of the group I and II were 2.2% and 3.5%, the positive rates of anti-HBs for the vaccinated people of the group I and II were 70.1% and 71.1% respectively. The most significant factor in positive rate of HBsAg was 'hepatitis carrier in family'. Multiple logistic regression analysis revealed that 'hepatitis history' and 'hepatitis carrier in family' were significant variables for positivity of HBsAg, and 'hepatitis B vaccination' was only a significant variable for positivity of anti-HBs.

In order to analyze the positive rate of hepatitis B surface antibody by age before and after hepatitis B vaccination, 13,855 serum specimens who were referred for the hepatitis B surface antibody test at the General Hospital of Jeju Hospital were examined by CMIA method. The positive rate of HBs Ab was 5,176 (37.36%). The positive rate according to gender was 40.13% for female and 34.77% for male. The age group with the highest HBs Ab average was in their 40's (399.86 mIU/mL), while the lowest age group was in the 90's (211.50 mIU/mL). It is remarkable that the age group with the highest HBs Ab positive rate is in the 30's, and that teenagers (age group of 10-20 years) had the lowest positive rate. Especially 15, 18, 19 years old was statistically significant. Consideration should be given to determining the titer of vaccination and to clarify the timing of vaccination.

Purpose : We have tried to search all concerning data on the policies of hepatitis B vaccination or surveillance of medical equipments that can transmit blood mediated diseases, including disposable syringe, in Republic of Korea, to propose references to other medical professionals. Methods : Data from domestic journals, government websites, computerized newspapers, etc. were reviewed. The data were arranged into four categories (governmental policies on hepatitis B control, hepatitis B mass immunization program in school, using process of hepatitis B vaccine, and policies on medical equipments surveillance, including disposable syringes, which is considered as source of blood mediated infection), and the periodic changes on each subjects in policies were reviewed. Results : Due to growing social concerns on hepatitis B in early 1980s, swift introduction and production of hepatitis B vaccine was made. After establishment of "5 year project for eradication of hepatitis B" in late 1983, number of vaccinated population jumped up to 6 million within 2 years (1984-85). However, since the immunization targets were mainly adult, not infant, this project was annulled in late 1985. Following this project, hepatitis B mass immunization program in school was carried out. In year 1995, hepatitis B vaccine was included in national immunization program. The use of disposable syringe was recommended from year 1980 but legislated in year 1985, finally. Conclusion : The mainstay in controlling hepatitis B in Republic of Korea was coordination of prompt introduction of vaccine, mass immunization, high vaccination coverage rate, or use of disposable syringes. However, since there is lack of official data available, it is urgent to arrange and computerize all government data related to infectious diseases.

현재 우리나라는 보건소 중심의 예방접종등록사업을 진행 중에 있다. 2004년부터 시작된 이 사업은 현재는 전국민을 대상으로 실시하고 있다. 예방접종등록사업은 피접종자들은 대체적으로 예방접종에 대한 적절한 시기를 판단할 수 있는 정보가 부족하기 때문에 예방접종과 관련된 정보들을 국가나 사회에서 적시에 피접종자들에게 제공해 줄 수 있다. 따라서 이에 대한 확인이 등록에 앞서 그 정확성을 확인 필요가 있다. 예방접종등록사업의 가장 기본적인 사업으로 진행된 것은 예방접종 수첩의 제공과 그 관리를 통한 예방접종 사업으로 지속적으로 전개되어 왔으며, 일반 국민과 개원의사들에서도 대중적으로 보급되어 있다. 국가 예방접종률의 산출 그리고 취학 어린이 예방접종력 증명서 제출 제도를 위하여 예방접종 수첩을 활용하는 방법이 현실적으로 유용할 수 있다. 따라서 예방접종 수첩의 예방접종력 정확성을 확인할 필요가 있다. 지역조사에서 접종기관으로 확인된 민간 의료기관 365곳 가운데 의료기관 이전 및 폐업으로 반송된 경우가 4건(1.1%)이었으며, 응답한 경우는 129곳으로 응답률은 35.3%였다. 조사된 의료기관 전체를 대상으로 확인된 1,201건에 대한 BCG 접종여부의 정확도는 69.5%였다. B형 간염의 정확도는 1차가 41.3%로 낮았으며, 2차와 3차는 각각 76.6%, 79.7%였다. DTaP의 정확도는 약 80%였으며, 정확도가 제일 높은 것은 DTaP 3차로 82.5%였으나 다른 것과 가장 낮은 정확도와 2% 정도 밖에 차이가 나지 않았다. 폴리오의 정확도는 약 80%였다. MMR의 정확도는 83.2%였다. 일본뇌염의 경우 약 80.0%였으며, 수두의 정확도는 74.9%로 다른 질병과 비교하여 낮은 수치를 보였다. 조사된 의료기관을 전체로 한 기타예방접종별 예방접종수첩의 접종여부의 정확도는 인플루엔자는 정확도는 74.1%였으며, 뇌수막염은 72.7%의 정확도를 보였다. A형 간염 1차의 정확도79.5%였으며, 폐렴구균 1차의 경우 73.2%로 나타났다. 국가필수예방접종별 예방접종수첩의 접종일자에 대한 정확도는 BCG 80.1%로 확인되었고, B형 간염 1차 89.7% 2차는 82.1% 3차는 79%로 B형 간염 중 가장 낮은 정확도를 보였다. DTaP는 1차와 2차는 약 87% 3차는 85.1% 4차는 83.5%로 확인이 되었다. 폴리오는 1차가88.1%로 가장 높은 정확도를 보였고 그 다음으로 2차가 86.2%, 3차가 84.8%로 확인되었다. MMR의 정확도는 84%였으며, 일본뇌염 1차의 정확도는 83.1%로 나타났다. 수두의 접종일자 정확도는 83.7% 이고, 인플루엔자의 정확도는 55.3%로 상대적으로 낮은 수치를 보였다. 기타예방접종별 접종일자 정확도의 조사 결과 뇌수막염 1차과 폐렴구균 1차는 약 90%로 상대적으로 높은 정확도를 보였고, A형 간염 1차는 88.4%의 정확도를 보였다.

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.
