  • Enteroviruses isolation were attempted from samples obtained from aseptic meningitis-suspected patients in hospitals in Busan during 2000-2002. Enteroviruses were found in 2 of 292 cases in 2000, 4 of 371 cases in 2001, 83 of 703 cases in 2002. In 2000, the isolated viruses were found to be echovirus serotype 11 and coxsackievirus serotype B2. Coxsackievirus serotype B5 was isolated in 2001 and in 2002, echovirus serotypes 2, 3, 6, 7, 9, 13, 25, 30 were isolated in 70 cases while coxsackievirus serotypes B3 and B4 were isolated in 10 cases. Various specimens tended to emerge over the years. The occurrence in 2000 tended to be mostly focus during the cold months, December through January, while in 2001, it occurred in May. In 2002, occurrence was found to be distributed from April to November with the highest rate during June and July. The strains of Vero and HEp-2 of echovirus and coxsackievirus, respectively, are highly infectious. Electron micrograph of echovirus and coxsackievirus show that they are small nonenevolped, isometric-shaped viruses. Isolated RNA from strains of echovirus and coxsackievirus showing cytopathic effects were used to undergo nested PCR which resulted in a 436 bp single band in all the strains. The serotype was sent to the Department of Virology at the Korean National Institute of Health for identification.

  • This study examines recent trends in income inequality among the elderly in Korea. Aggregate income inequality trends are explained by examining evidence from inequality index decomposition by population subgroup and by income source. Data come from Korean Labor and Income Panel Study(KLIPS). The results are as follows. First, elderly income inequality increased from 1999 to 2002, and then decreased until 2008. Second, household composition changes appear to have disequalizing influence. The proportion of elderly people who are economically dependent on non-elderly family member or living with adult children has declined. Equalizing influence of private transfers also decreased between 2002 and 2008. These results indicate that the redistributive role of family has weakened over time. Third, the improvement of education level and changing occupational structure among the elderly household head contributed to increase in elderly income inequality. Fourth, earning's factor share has declined steadily, and the diminishing role of earnings provides equalizing influence on elderly income inequality from 2002 to 2008. Fifth, the impact of recent expansion of social insurance has changed over time. Inequality contribution of social insurance income increased from 1999 to 2002, and then decreased from 2002 to 2008.

  • The incidence of virus disease on peppers was investigated at the 52 areas in the whole country in 2002, 2004 to 2006. Among the six viruses, Cucumber mosaic virus (CMV), Pepper mottle virus (PepMoV), Pepper mild mottle virus (PMMoV), Broad bean wilt virus 2 (BBWV2), Tobacco mild green mosaic virus (TMGMV) and Tomato spotted wilt virus (TSWV), infecting peppers in Korea, the incidence of CMV, PepMoV, PMMoV and BBWV2 was 29.4%, 13.6%, 14.3%, 25.6%, orderly. TMGMV and TSWV had the same low infection rate of 1.0%. The infection rate of CMV was higher as 53.3% and 34.2% in 2002 and 2004, but it was decreased to 18.2% and 11.9% in 2005 and 2006, respectively. The infection rate of BBWV2 was lower as 1.3% in 2002 and 1.8% in 2004, but it was increased abruptly to 41.3% in 2005 and 58.2% in 2006. For the types of mixed infections of pepper viruses, the incidence of CMV+PepMoV was 62.6% in 2002 and 50.0% in 2004, and that of CMV+BBWV2 was increased suddenly from 33.3% in 2005 to 83.2% in 2006. The triplex infection of CMV+BBWV2+PepMoV was 6.4% in average. CMV caused severe mosaic and BBWV2 induced ring spots, and the two mixed virions caused chlorosis on the leaves of red peppers. TSWV induced the typical symptoms of multiple ring spots on the leaves and fruits of red peppers.

  • Influenzavirus were isolated from patients with acute respiratory infections in Busan during 2000-2002 and characterized their antigenic properties. In 2000, 39 viruses were isolated and they were identified as Influenzavirus. Among the isolated influenzavirus, 23 were A type influenzavirus and 16 were B type influenzavirus. As a result of antigenic characterization, the influenzavirus were determined to A/Sydney/05/97 (H3N2)-like, A/Beijing/262/95 (H1N1)-like, and B/Harbin/07/94-like virus. In 2001, 56 viruses were isolated and all of the viruses were identified as influenzavirus. They were A/Panama/2007/99 (H3N2)-like and A/Newcaledonia/20/99 (H1N1)-like virus In 2002, 114 Influenzaviruses were isolated. Among the isolated influenzavirus, 83 were A type influenzaviruses, and 31 were B type influenzaviruses. They were A/Panama/2007/99 (H3N2)-like, A/Newcaledonia/20/99 (H1N1)-like and B/Beijing/243/97, B/Honkong/22/2001, B/Sichuam/379/99-like virus when determined their antigenic properties. These results may be useful for the establishment of reliable epidemic data.
