  • Purpose : Hepatitis A viral infections have been continued after re-emerging since mid 1990s in Korea. The incidence of this disease has been increased in young adults younger than 30 years of age since 2000. This study was performed to evaluate the prevalence of antibody to hepatitis A in Korea(two regions; Incheon and Changwon) in 2005, and was compared with the results of similar studies in mid 1990s. Methods : The study was conducted from January 2005 to June 2005, and consisted of 1,301 enrolled subjects, neonates to 50 years old, living in Incheon and Changwon in Korea. All sera were frozen and stored at $-70^{\circ}C$ until assayed. Anti-HAV IgG antibodies were measured by microparticle enzyme immunoassay(HAVAB, Abbott Lab., IL, USA). Results : The prevalence of anti-HAV IgG was 61.1% in infants younger than 1 year old, 30.5% in 1~5 years, 14.6% in 6~10 years, 1.7% in 11~15 years, 6.5% in 16~20 years, 36.6%in 21~30 years, 77.5% in 31~40 years, and 99.8% in 41~50 years. Statistical differences were not found between male and female, but there was statistical difference in 6~10 years old age group between the two areas. Conclusion : Our study indicate that the prevalence of antihepatitis A virus antibody has shifted from children to old adolescents and young adults. This result suggests that the risk of sudden outbreaks or increasing incidence of hepatitis A viral infections in young adults may be expected in our society. The preventive strategies of hepatitis A including vaccination should be prepared.

  • Purpose : To assess the immunogenicity, safety, and tolerability of hepatitis A vaccine ($VAQTA^{TM}$) in healthy children and adolescents. Methods : Eligible subjects aged 2 to 17 years received 25 U/0.5 mL of $VAQTA^{TM}$ intramuscularly at 0 and 24 week schedule. Bleeds were obtained prior to vaccination and 4 weeks after the second dose to ascertain serostatus. To detect antibody to HAV after vaccination with an inactivated HA vaccine, a modification of the $Abbott^{(R)}$ HAVAB kit was used. Sample with titers ${\geq}10$ mIU/mL were considered seroconverted. Adverse experiences were monitored. Results : 102 subjects(54 male, 48 female) were enrolled. The mean age was $6.8{\pm}3.5$ years. Two subjects were seropositive, two were lost of follow up. 88 subjects were available for a per protocol analysis and 90 for all subjects with serology after the second dose, and ten withdral. All subjects(95% CI, 94.8~100) seroconverted. Geometric mean titers was 7,991.1(95% CI, 6,481.1~9,852.7) with very little difference in per protocol analysis and all subjects analysis. Adverse experiences to $VAQTA^{TM}$ were generally mild and transient. Conclusion : The pediatric two-dose regimen of $VAQTA^{TM}$ was found to be highly immunogenic, generally well tolerated and resulted in 100% seroconversion. Regarding Korea is in transition from a high to low risk region resulting in a paradox increase of clinical disease and disease burden, routine vaccination should be considered in order to control hepatitis A effectively.

  • Purpose: This retrospective study was performed to identify the clinical characteristics of influenza B infection and compare to influenza A infection. Methods: Medical records of patients diagnosed with influenza using a multiplex PCR test, admitted to Seoul St. Mary's Hospital, during the 2011-2012 influenza season were analyzed. Clinical and laboratory characteristics of influenza B patients were investigated and compared with those of influenza A patients. Results: A total of 145 influenza patients were enrolled during this study period. Among these, 66 and 78 patients were diagnosed with influenza A and B, respectively, and 1 patient was diagnosed with co-existing influenza A and B. Cough (88.2%), rhinorrhea (77.1%) and sputum (60.4%) were the most common symptoms among these influenza patients, and most were diagnosed with upper respiratory infection (31.9%) or lower respiratory infection (49.3%). In comparison to influenza A patients, influenza B patients were older ($4.7{\pm}4.1$ years vs. $3.3{\pm}2.5$ years, P=0.016), and the number of fever days before hospitalization were longer (3.0 days vs. 2.5 days, P=0.043). While sore throat (10.3% vs. 1.5%, P=0.039) and vomiting (20.5% vs. 6.1%, P=0.012) were more common in influenza B patients than in influenza A patients, other clinical and laboratory characteristics were not significantly different between the two groups. Conclusions: No significant differences in clinical and laboratory perspectives were manifested in influenza A and B infections. Preventive measures should be emphasized over treatment in influenza B due to prolonged fever duration before admission.

  • This study investigates convergent influence on job seeking stress and its association with self esteem, hopelessness, depression, locus of control and type A behavior pattern among some college women. The survey was administered to 531 college women in Jeonbuk area from March 28th to April 29th, 2016. The structured self-administered questionaries were used. The results of hierarchical multiple regression analysis show the following. The job seeking stress of respondents turned out to be significantly higher in following groups: a group in which self esteem is lower and groups in which hopelessness, depression, external locus of control and type A behavior pattern are higher. Their explanatory power was 43.2%. With the analysis of covariance structure, we could confirm relationship among the four factors such as self esteem, hopelessness, depression, locus of control, type A behavior pattern and job seeking stress. The results of the study indicate that the efforts, to increase self esteem, and to decrease hopelessness, depression, locus of control and type A behavior pattern, are required to reduce the job seeking stress of the college women. The results are expected to be useful for the development of program and policy to decrease the job seeking stress of the college women. In the following study, the analysis about additional factors of influence on job seeking stress will be needed.
