This study was conducted to investigate the distribution and the population dynamics of Hipparchia autonoe by using a line transect and Mark-Release-Recapture (MRR) at the Mt. Halla in Jeju Island. The results showed that H. autonoe was found from 1,500 m above the sea level. Total 1,493 H. autonoe with 978 males and 515 females were captured and released in the MRR study site. Among them, 518 individuals including 284 males and 234 females were recaptured. The average survival time was 2.31 days with 2.14 days for males and 3.47 days for females, indicating longer survival time in case of females than males. The daily population size of males estimated in the MRR study site was maintained about 1,000 individuals in July and gradually decreased less than 200 in August. The number of females showed peak at 335 individuals on July 24, and gradually decreased less than 120 in August. Thus, female population was 1/3 of males. The average travel distance of male and female H. autonoe were $116.8{\pm}191.9m$ and $118.4{\pm}161.5m$, respectively, indicating almost same between sexes. H. autonoe in the Mt. Halla formed single population group in the wide meadow around the Baekrokdam Lake. The highest population density of H. autonoe was occurred in the restored area from damages, where host plants such as the sheep's fescue or the food plant are abundant by artificial restoration efforts.

The purpose of this study was to evaluate results of cervix cytology screening in the community and to determine the risk factors of cervical abnormality. Branch of Daejeon city and Chungnam Province, The Planed Parenthood Federation of Korea had conducted cervical cancer screening of 146,848 married women in Chungnam province from 1995 to 1999. Cervical cancer screening was Pap smear using cytolgic brush swab by trained nurse. Women who had abnormal finding of 1st Pap smear screening were followed re- examination and 2nd close examination. Crude prevalence rate of cytologic abnormalities for 1st screening results was 0.63% in 1995- 1999(1995 0.68%, 1996 0.59%, 1997 0.70%, 1998 0.56%, 1999 0.62%). Crude prevalence rate of above class III for 1st screening results was 0.61%, but crude prevalence rate of above class III for the results of re- examination and 2nd close examination was 2.2/ 1000. The false-positive rate of class III, IV and V for positive findings were defined above class II(cervicitis) results were 52.6%, 26.9% and 19.0%, respectively. And the false- positive rate of class III, IV and V for positive findings were defined above class III(dysplasia) results were 75.3%, 46.2% and 47.6%, respectively. Major predictors of risk factors for abnormal results of cervix screening on the multiple logistic regression were age, educational attainment and living area. The false-positive rate of cervix cytology screening in the community were highest result so cervix cytology screening should be improve for better diagnostic power. And the finding of logistic regression would be understand within the limit of experimental trials on the relationship between cervical disease and risk factors.
