This study aims to prepare damage by typhoon in Korea, which is needed to examine annual changing trends of typhoon. In order to examine changing trends of typhoon, this study analyzed and compared annual change depending on various characteristics of typhoon between 1990s and 2000s. The selected characteristics of typhoon is that Path, Frequency, water temperature in the Southern coas, wind velocity, center pressure and radius. Additionally, this study examined damage and precited changing trends of typhoon based on analyzed characteristics of typhoon. 본 연구는 우리나라에 내습하는 태풍에 의한 피해를 줄이기 위하여 태풍의 경년변화 경향을 살펴 피해에 대비하고자 한다. 태풍의 변화경향을 살펴보기 위하여 태풍의 특성을 1990년대와 2000년대로 나누어 비교·분석하였다. 태풍의 특성은 경로, 발생 수, 남해안 수온, 풍속, 중심기압, 반경으로 총 6가지의 다양한 요소들을 선정하였다. 각 요소들을 분석한 결과를 토대로 태풍으로 인한 피해를 검토하고 변화 경향을 예상하였다.

Since 1970s, the rapid urbanization process by industrial and economic development in Korea causes to a severe change of surface roughness and recent abnormal weather by global warming causes to increasing the intensity of strong wind and Typhoon. It is necessary to revise basic wind speed map of Korean Building Code 2009(KBC-2009) drowned by past meteorological data from 1951 to 1995. This paper proposes new basic wind speed map corresponding to a return period of 100 years in Korea. The values are established from data of annual-maximum 10-minute mean wind speeds collected at 68 meteorological offices recent past 40 years from 1973 to 2012. They were standardized homogeneously to an altitude 10m above the surface roughness category C. Surface roughness category was determined by surrounding surface conditions of meteorological station in 1999 and 2012. The data were statistically reduced using extreme value analysis procedures based on Gumbel’s distribution, and the expected wind speeds corresponding to a return period of 100 years (it is called as basic wind speeds) were calculated for each region. The equivalent wind speed contour line to a return period of 100 years were drown up interval of 2m/s to the map of Korea. The basic wind speeds of this study were compared with those of KBC-2009, and the causes of wind speed up or down were described. The basic wind speed map of this study shall be used to revise that of KBC-2009.

Objectives: To investigate the distribution and functional significance of $CYP11{\alpha}$ $(tttta)_n$ microsatellite polymorphism in Korean patients with polycystic ovary syndrome Materials and Methods: Analysis of $CYP11{\alpha}$ $(tttta)_n$ microsatellite polymorphism was carried out on DNA samples from 97 patients with polycystic ovary syndrome and 70 normal controls. Comparison were done between PCOS patients and controls concerning $CYP11{\alpha}$ $(tttta)_n$ microsatellite polymorphism genotype or allele frequencies. Results: The most frequent allele observed in the controls was an allele with six repeats (60.7%). Significant difference in the frequency of genotype (4R (-) genotype) having no copy of four-repeatallele were observed between PCOS patients and controls (66.0% vs 34.0%, p=0.038, OR=1.939). But no significant difference was observed in the serum levels of total testosterone or free testosterone between 4R (+) genotype and 4R (-) genotype among PCOS patients. However, hyperandrogenic PCOS patients with 4R (+) genotype showed a higher serum testosterone levels compared to controls (mean $\pm$ S.D: $0.49{\pm}0.21\;ng/ml$ vs $0.37{\pm}0.18\;ng/ml$, p=0.037). Conclusion: The alleleic distribution of $CYP11{\alpha}$ $(tttta)_n$ microsatellite polymorphism in Korean subjects were different from those reported in Caucasians. $CYP11{\alpha}$ $(tttta)_n$ microsatellite polymorphism was associated with polycystic ovary syndrome in the Korean population, and may play a role in the synthesis of androgens in patients with polycystic ovary syndrome.
