The present study was undertaken to observe the immune status of breeding hens and laying hens against Newcastle disease (ND). The methods of extraction of hemagglutination inhibition (HI) antibody from egg yolk, the detection of HI antibody in egg albumen and the correlation between HI antibody titers in maternal sera and egg yolks were discussed. For the purposes of these experiments, 9 flocks of breeding hens and 16 flocks of laying hens immunized against Newcastle disease virus were investigated. The vaccination program of tested flocks was 3-3-3 or 4-4-4 in general. The results obtained are summerized as follows: Freezing-thawing was the best method far antibody extraction from egg yolk for HI test. The HI antibody against NDV was found in egg albumen (geometric mean, 4.5), but lower than that found in egg yolk (32.1). The geometric mean of HI antibody titers of egg yolks (84.1) was higher than that of maternal sera (68.4) and day-old chicken sera (25.3). There was correlation between HI antibody titers of maternal sera(Y) and those of egg yolks(X). The coefficient correlation was r=0.63, and the line of regression of Y on X was $\hat{Y}$=35.91+0.35X.

Rabies virus (family Rhabdoviridae, genus Lyssavirus, RV) is the causative agent of rabies in mammals. We conducted a sero-epidemiological survey for RV using sera from South Korean stray and companion dogs in the present study. A total of 533 canine serum samples were collected between February 2006 and December 2007 and were screened for rabies immunity with a neutralizing peroxidase linked assay. Both companion (49.1%) and stray (60.1%) dogs demonstrated RV seropositivity. Regional RV antibody prevalence was measured in the Jeju (87.5%), Gyeonggi (62%), Gyeongsang (59.1%), Jeonra (42%), Chungcheong (37.9%), and Gangwon (30.4%) provinces. Prevalence increased with age but did not exceed 80% in any age group. Stray and companion dogs had RV antibody prevalence values of 26.7% and 23.7%, respectively. Seroprevalence was significantly associated with age $({\chi}2\;=\;9.46;\;p\;=\;0.024)$ for companion dogs, although this association was not evident in stray dogs. There were no significant differences in age between stray and companion dogs and no gender differences in RV seroprevalence. Our results suggested that a widespread and reinforced vaccination program must be applied to Korean dogs.

Purpose: The purpose of this study was to identify health promotion services in rural areas and factors influencing this service. Method: From March to April, 2007, a structured questionnaire on services in 2006 was used to collect data from community health practitioners in all of the Primary Health Care Posts (PHCP) in North Chungchong Province. Collected data were analyzed using SPSS 12.0 Win program. Results: The most frequently offered programs were health gymnastics, walking exercise, bathing and vaccination service, and hypertension management. The main obstacles to these health services were lack of adequate space, insufficient budget, and overwork. The most frequently offered health education programs were education on hypertension, exercise, diabetes, volunteer work, and smoking cessation. The main obstacles to health education were lack of adequate space, insufficient education materials and equipment, and lack of cooperation from the citizens. Improvement and reinforcement of health promotion programs should include support of specialist, development of appropriate methods of service delivery, and education materials, and increase ease in using community resources. Conclusions: The research results show that a new model of health promotion must be developed for efficient health promotion programs in rural PHCP.

The main purpose of this research is to measure and analyze how productive the health centers are and how much inputs(or outputs) in the inefficient health centers should be decreased(or increased) for efficiency. The evaluation of the performance of health centers gives a strong incentive to improve resource allocation in regional health planning. It has been, however, implemented very rarely until now. In this regard, this paper measures the performance of the health centers with a single indicator for multiple-outputs in terms of productivity(technical efficiency), based on Data Envelopment method. The 20 Kyungnam health centers which provide clinic services and specific primary health care services were analyzed. The results show that 50.0% of 20 health centers were productive with respective to overall technical efficiency, 65.0% were productive for pure technical efficiency, and 50.0% for scale efficiency. The inefficient group includes Geoje, Mahsan, Miryang, Sahchun, Tongyoung, Gosung, Nahmhae, Euryang, Hahmahn, Hahbchun health centers. The worst case was identified as Tongyoung health center which represented a 47.5% efficiency, compared with productive health centers. The empirical results for input-output analysis indicates that the low-productive health centers have excessive manpower in administration department, producing low outputs in clinical services and vaccination program. These findings imply that a systemic evaluation of the performance of the Korean health centers and the subsequent structural reform are strongly required.

This study was carried out to provide the fundamental information for development of proper vaccination program against infectious bursal disease(IBD) to the local chicken farms. The antigen detection was peformed from 8 samples of bursa of Fabricius with agar gel precipitation(AGP) and indirect immunofluorescent assay(IFA), And also, the antibodies in serum samples were detected by the various serological methods such as commercial ELISA assay, AGP and virus neutralization(VN) test. 1. The antigen detection rates were 25% for AGP which is 2 out of 8 farms and 10 out of 40 bursas, and 25% which Is 2 out of 8 farms and 20% 8 out of 40 bursas for IFA, respectively. 2. The mean titer of maternal antibody (>3,000) existed until 10 days of the age with ELISA-GMT. 3. The antibody positive rates which are over 80% showed until 5 days of the age with ELISA and at 10 days of the age with AGP except one, but none of them showed from 1 day of the age. This report came to conclusions that both the protective maternal antibody titers and the antigen positive rates were significant until at the 10 days of the age.

Chronic hepatitis B viral (HBV) infection remains a major health threat, especially in high-prevalence areas. Most infants infected by mother-to-infant HBV transmission become chronic carriers. In Taiwan, many important preventive interventions have been implemented to block the perinatal transmission of HBV in the past 35 years. The first nationwide universal HBV vaccination program was launched in Taiwan in July 1984. The three-dose HBV vaccine completion rate reached 98.1% in 2018. The prevalence of Hepatitis B surface antigen (HBsAg) decreased from 9.8% in pre-vaccinated period in 1984 to 0.5% in the vaccinated cohort in 2014. The incidence of hepatocellular carcinoma in children aged 6-9 years significantly declined from 0.52 to 0.13 per 100,000 children born before and after 1984, respectively. Furthermore, we have performed a maternal HBV screening program during pregnancy since 1984, with the screening rate peaked at 93% in 2012. The HBsAg- and HBeAg-seropositive rate in pregnant women declined from 13.4% and 6.4% in 1984-1985 to 5.9% and 1.0% in 2016, respectively. To closely control perinatal HBV infection, we have administered hepatitis B immunoglobulin immediately after birth and checked the serum level of HBsAg and anti-HBs in high-risk babies born to HBsAg-seropositive mothers, irrespective of their HBeAg status, since July 2019. We have also adopted short-term antiviral treatments such as tenofovir 300 mg daily in the third trimester for highly viremic mothers and reduced the perinatal infection rates from 10.7 to 1.5%. Through all these efforts, we expect to meet the global goal of eliminating HBV infection by 2030.

Objectives: This study was intended to provide the base of developing countries' Health Partnership Strategy by investigating the Paraguay's awareness level of health and analyzing the actual state. Methods: The data was collected from 11 government employees, 20 hospital staffs, 26 local residents on Asunci$\acute{o} $n, Paraguay in February, 2012. The method of the study was the questionnaires consisting of 62 questions including 7 questions of general features, 3 questions of awareness on maternal health care, child health care, planned parenthood program, 52 questions of awareness on health. The questionnaires was translated into Spanish which is local language in Paraguay. Results: The results of this study are summarized as follows; 1) The most important awareness on maternal healthcare, child healthcare, planned parenthood program was providing child health care. 2) The most important awareness to prevent non-health behavior was sufficient nutrition. The most important awareness to reduce the rate of chronic disease was diabetes. The most important awareness to eradicate communicable disease was HIV/AIDS. 3) The most important awareness to provide healthcare service was vaccination. 4) The most important awareness on healthcare delivery system was policy. The most important awareness on health education was student's health education. 5) The most important awareness to strength healthcare capacity was developing domestic economy. Conclusion: The results of this study suggest that awareness levels on health are high against low health behavior status in Paraguay. But awareness on health can lead to health behavior by healthcare system. Therefore, it has to induce the healthcare network and system by injecting public health funds, infrastructure, human resources on prevention of disease and healthcare management.

Purpose: The coronavirus disease 2019 (COVID-19) pandemic has had significant physical and psychological impacts on registered nurses (RNs). This study aimed to identify long COVID symptoms and their associated factors specifically among RNs. Methods: This descriptive correlational study's sample comprised 189 nurses (31.57±5.98 years, 93.7% female) in Korea. Self-reported long COVID symptoms were assessed using the COVID-19 Yorkshire Rehabilitation Scale. Data were collected from December 31, 2022, to January 13, 2023, using the online survey method and were analyzed using independent t-test, Wilcoxon signed-rank test, one-way ANOVA, Pearson's correlation, and a multiple linear regression analysis with the IBM SPSS Statistics 26.0 program. Results: A total of 179 participants (94.7%) experienced one or more long COVID symptoms. The most prevalent symptoms were weakness (77.8%), fatigue (68.3%), breathlessness (67.7%), cough/throat sensitivity/voice change (50.3%), and sleep problems (50.3%). The factors related to long COVID symptoms were marital status, type of institution, working time, acute COVID-19 symptoms, and vaccination status. The quarantine period (β=.26, p<.001) and the nursing workforce after COVID-19 (β=-.17, p=.018) were significantly associated with long COVID symptoms (Adjusted R² =.33). Conclusion: Providing comprehensive recognition is necessary for the understanding of long COVID symptoms and their associated factors among nurses and could promote a long COVID symptom management education program targeted at nurses. Moreover, it could facilitate effective nursing care and education plans for long COVID patients.
