The purpose of this study was to apply Ajzen's theory of planned behavior to identify factors that affect nursing students decisions to receive Human Papilloma Virus(HPV) vaccination. Data collection was done using self-report questionnaires with 195 nursing students in D city. Data were analyzed using percentage, mean, standard deviation, t-test, Pearson correlation analysis and hierarchial regression with the SPSS Win 25.0 Program. The mean score of intention to receive HPV vaccine was 5.24±1.66 out of a possible 7. In the hierarchial regression analysis, attitudes (β=.446, p<.001), perceived behavior control (β=.321, p<.001) subjective norm (β=.132, p=.041), to receive HPV vaccine were significant predictors and explained 54.4% of intention to receive HPV vaccine. it is suggested that promotion programs and social environment to encourage to think it positively and perceive it easy and convenient should be developed, with nursing students' educatinon for sex education and public relations activitiesas as a nursing educators.

Vaccine development is one of the key efforts to control the spread of coronavirus disease 2019 (COVID-19). However, it has become apparent that the immunity acquired through vaccination is not permanent, known as the waning effect. Therefore, monitoring the proportion of the population with immunity is essential to improve the forecasting of future waves of the pandemic. Despite this, the impact of the waning effect on forecasting accuracies has not been extensively studied. We proposed a method for the estimation of the effective immunity (EI) rate which represents the waning effect by integrating the second and booster doses of COVID-19 vaccines. The EI rate, with different periods to the onset of the waning effect, was incorporated into three statistical models and two machine learning models. Stringency Index, omicron variant BA.5 rate (BA.5 rate), booster shot rate (BSR), and the EI rate were used as covariates and the best covariate combination was selected using prediction error. Among the prediction results, Generalized Additive Model showed the best improvement (decreasing 86% test error) with the EI rate. Furthermore, we confirmed that South Korea's decision to recommend booster shots after 90 days is reasonable since the waning effect onsets 90 days after the last dose of vaccine which improves the prediction of confirmed cases and deaths. Substituting BSR with EI rate in statistical models not only results in better predictions but also makes it possible to forecast a potential wave and help the local community react proactively to a rapid increase in confirmed cases.

Purpose : This study was carried out to obtain the vaccination rate and age appropriateness of vaccination in children under five years of age in Jeonbuk province. Methods : Eight hundred and fifty infants and children were enrolled in this study. Vaccination rate(Number of vaccinees/Number of subjects), places of vaccination, age appropriateness of vacination were examined by either vaccine record review or interview with parents or guardians. Results : The salient features of the findings were as follows : All subjects were aged under five and mostly under two years of age(68.8%). Places of vaccination were health centers or subcenters( 50.4%), private clinics(44.3%), and general hospitals(5.3%). Routine vaccinations such as BCG, hepatitis B vaccine(HBV), diphtheria, tetanus, acellular pertussis(DTaP) and Trivalent Oral Polio Vaccine(TOPV), measles, mumps, rubella(MMR), and Japaneses B encephalitis(JBE) were vaccinated mostly in health centers or subcenters, while chickenpox(CHP) and haemophilus influenzae vaccines(Hib), which are not routine in Korea, were vaccinated in private clinics. The vaccination rates of BCG(99.2%), HBV(93.5%) and DTaP(96.1%) were very high. But those of MMR(83.7%), CHP(72.5%), JBE(50.2%), and Hib(15.8%) were lower than expected. Considering the age appropriateness of vaccination, some infants and children were not appropriately vaccinated(vaccination rate/age appropriateness of vaccine; HBV, 93.5%/88.4% : DTaP, 94.6%/73.1% : JBE, 50.2%/ 18.5%). Conclusion : The vaccination rate of BCG, HBV, DTaP and TOPV was very high, but MMR, CHP, JBE, and Hib vaccination rate was not high enough to be able to protect against epidemic. We should pay more attention to vaccinating children, and there is a need for a program that will enhance coverage for vaccines.

Background: Acute alcoholic intoxication patients (AAIP) are a common public health problem. The aim of this study was to perform a comprehensive laboratory analysis for these patients to investigate the co-morbid medical problem. Methods: We retrospectively reviewed laboratory findings of AAIP who were transferred to the emergency department (ED) from January 2017 to June 2017. Results: A total of 160 male patients were enrolled. Sixteen patients (16/160, 10.0%) and three patients (3/160, 1.9%) had macrocytic anemia and microcytic anemia, respectively. A total of 33 patients (33/160, 20.6%) showed thrombocytopenia ($<150{\times}10^9/L$). Twelve patients (12/159, 7.5%) showed low serum albumin level (<3.5 g/dL). Three patients (3/160, 1.9%) had chronic kidney disease stages 3-4 based on estimated glomerular filtration rate. Six patients (6/27, 22.2%) had high hemoglobin A1c (HbA1c) level (>7.0%). Positive rates of hepatitis B surface antigen and antiHBs antibody (anti-HBs Ab) were 3.5% (5/141) and 49.0% (68/141), respectively. Conclusion: Patients with AAIP who were transferred to ED had various laboratory abnormalities (anemia, thrombocytopenia, high HbA1c). They had low positive rate of anti-HBs Ab. This might be a public health problem, suggesting the need of hepatitis B virus vaccination program for AAIP. Our data suggest the need of further nationwide studies.

Immunization has been one of the most effective measures preventing from infectious diseases. However, children routine vaccination rate of Korea was 68.2% and it was not higher than expected. Korean government revised the School Health Law for every primary school children to submit the vaccination certificate record from 2005. It is quite important national Infectious disease prevention policy to keep the immunizations rate high and monitor the immunizations rate continuously. To do this, National Institute of Health introduced the National Immunization Registry(NIR) Program at 2000. Objective : The aims of this study was to evaluate the Immunization Registry program which has been implementing since 2000 at the Public Health Centers(PHC). Methods : The mail survey was done from November 2001 to January 2002. 169 (69%) Public Health Centers among 244 PHC were responded. Results : The respondents of PHC sud the Immunization Registry(IR) program had reduced the workload (18.5%). 69.2% said they inputted the immunization data into the IR program after the shots were given. 86.5% said they hadn´t checked or retrieved the children lists who had missed the scheduled immunization. Only 17.2% said the speed of internet for the R program was good. It showed that 20% of respondents hadn´t written down documents, records on immunization any more. Even there were a lot of negative results, the respondents of PHC thought that the IR program was effective. They especially agreed that the IR program could make the job accurate (81.5%), convenient (71.3%), and reduced the chances of making mistakes (71.3%), increase the service quality (78.5%). And they were well adapting the job process of the IR (79.63%). Bivariate analysis showed that the software program was the important determinants of IR success. The only Bit Computer software program has been evaluated to be less satisfactory than the Integrated (Posdata operating system + Bit software) program. Other variables, such as age, duration of present job, and location of PHC (metropolitan, small city, rural area) were not significantly related. Conclusion : It seemed that the success of NIR might depend on the software program. Because Integrated program, which has been developed from 1994, include not only the general operating and management program for PHC but also IR program. It was natural to prefer Integrated program to Bit software program. So we can suggest that it is essential for the NIR to be successful that not only the immunization software program but also hardware equipments and public health information system should be further improved.

Outbreaks of porcine reproductive and respiratory syndrome virus (PRRSV) in vaccinated sow herds from occurrence to stabilization were monitored and analyzed in terms of serology and reproductive performance. Three different conventional pig farms experienced severe reproductive failures with the introduction of a type 1 PRRSV. These farms had adopted mass vaccination of sows using a type 2 PRRSV modified live vaccine (MLV). Therefore, to control the type 1 PRRSV, an alternative vaccination program utilizing both type 1 and type 2 MLV was undertaken. Following whole herd vaccinations with both types of MLV, successful stabilization of PRRS outbreaks was identified based on serological data (no viremia and downward trends in ELISA antibody titers in both sows and suckling piglets) and recovery of reproductive performance. Additionally, through comparison of the reproductive parameters between outbreak and non-outbreak periods, it was identified that PRRSV significantly affected the farrowing rate and the number of suckling piglets per litter at all three pig farms. Comparison of reproductive parameters between periods when the different vaccination strategies were applied revealed that the number of piglets born in total and born dead per litter were significantly increased after the introduction of the type 1 PRRS MLV.

The purpose of this convergence study is to understand the knowledge of cervical cancer and its prevention of cervical cancer in unmarried women. 216 women were collected through self-report questionnaires and analyzed by SPSS program. In result, human papilomavirus vaccination was performed in 33.9%, pap test was performed in 7.9%. The human papilomavirus vaccination and pap test group were 6.7% and human papilomavirus vaccination or pap test group were 28.5%. According to the cervical cancer prevention activities, several differences were detected in the family history of cervical cancer, subjective norms of cervical cancer prevention, perceived behavioral control, and behavioral intention. Therefore, it is important to increase susceptibility of the prevention of cervical cancer in unmarried women, and it is important for the health professionals to perform the most meaningful support system preventing cervical cancer in unmarried women. In addition, various policies should be actively promoted that unmarried women participate in the prevention of cervical cancer actively.

Purpose: This study was to determine how attitude, subjective norm, and perceived behavioral control (PBC) were related to parents' intentions to vaccinate their sons in elementary school against human papillomavirus (HPV), applying the updated theory of planned behavior. Two hypotheses were examined: PBC would moderate the relationship of attitude to intention and subjective norm to intention, respectively. Methods: This was a cross-sectional study with 231 participants recruited in November, 2018. Inclusion criteria for the participants were parents with 5th-6th grade boys in elementary schools. The moderation effects of the hypotheses were analyzed using the PROCESS macro for SPSS. Results: PBC significantly moderated the relationship of attitude to intention on HPV vaccination. The simple effect of attitude to intention was significant under three different levels of the PBC (low, moderate, and high), but the magnitudes of the relationships were not homogeneous. The magnitude of the relationship between attitude and intention was the lowest for the parents with the low level of the PBC. In the relationship of subjective norm to intention on HPV vaccination, the moderating effect of the PBC was not supported. Subjective norm and PBC directly predicted the intention on HPV vaccination. Conclusion: In order to promote the parents' intentions to vaccinate their sons in elementary school against HPV, we need a program that can improve parents' attitude, subjective norm, and PBC, requiring special attention to the parents with the low PBC.
