Relation between SSTs(Sea Surface Temperatures) in the South Sea and intensity of typhoons which passed through the South Sea was analyzed for 36 years from 1970 to 2005. The SSTs in the South Sea show the rising trends continuously. The mean SST of the last 6 years(2000-2005) is higher 1.21$^{circ}C$ than the mean SST during 10 years(1970-1979). The rising trends are especially strong after 1994. The intensity of typhoon am be seen by the central pressure. The minimum central pressures of typhoons which passed through the South Sea show the descending trends. The mean minimum central pressure of the last 6 years(2000-2005) is lower 9hPa than t1m during 10 years(1970-1979). The correlation analysis shows that the rising of SSTs in the South Sea has relations with the strengthening of intensity of typhoons.

This paper describes the variations of geomagnetic field by analyzing the geomagnetic observation data, which spanned the period from 1918 through 1944 and the global geomagnetic model in Korea. Geomagnetic data observed at Incheon in the period of 1918~1944 and global geomagnetic model (IGRF-95) were obtained from the World Geomagnetic Data Center. In this study, the variations of geomagnetic declination is estimated as $1^\circ{50'}$ from 1918 to 2000 and the variation rate is given as the nearest 1'20"/yr. The total variation of inclination is about 38' for 82 years and the variation rate is estimated as the nearest 27"/yr."/yr.;/yr.

Three hundred sixty-eight samples of domestic PVC food packaging were analyzed fir DEHP(di-(2-ethyhexyl) phthalate) used in plasticizer by GC/FID and GC/MSD. The number of samples collected were 47(2000), 143(2001), 88(2002) and 89(2004) from local markets in Gyeonggi-Do. In $2000\∼2001$, DEHP was highly detected in 86 out of 190 samples and the level of DEHP were ranged from 1.3 g/kg to 82.8 g/kg. In 2002, meanwhile, DEHP was detected in 8 out ot 88 samples and the level of DEHP were shown to from 1.3 g/kg to 51.5 g/kg. In 2004, DEHP was detected in only one out of 89 samples and the amount was 30.5 g/kg. As a result of this study, it was made clear that the detection rates of DEHP in PVC food packaging were rapidly decrease every year.

In 2000 and 2018, phytosociological surveys were carried out in the forest vegetation of Mt. Yeompo, a representative isolated urban forest in Ulsan city. The trends of change in forest structure, composition, and spatial distribution were compared between years. Total percent coverage per 100 squaremeters of forest vegetation was similar, but natural vegetation showed a 9% increase. The importance of constituent species changed slightly. Specifically, Lindera erythrocarpa and Styrax japonicus showed very high growth rates of 835% and 269%, respectively. Species richness (S) and diversity (H') decreased by about 22% and 8%, respectively. Both S and H' showed slightly higher rates of decrease in artificial compared with natural vegetation. The constituent species life form spectrums were the same in 2000 and 2018 as 'MM-R5-D4-e'. The similarity (Jaccard coefficient) in the species composition of the forest vegetation was almost homogeneous at approximately 75%. The number of indicator species decreased from 16 species in 2000 to 7 species in 2018. This decrease was mostly due to a decline in herbaceous plants, such as Hemicryptophytes, Geophytes, and Therophytes, which are sensitive to disturbances. The spatial distribution of forest vegetation did not change significantly. The number of forest landscape elements (patches) increased by approximately 25% from 537 in 2000 to 721 in 2018, while the average size decreased by about 20% from 1.28 ha in 2000 to 1.03 ha in 2018.

대한결핵협회는 지난 1965년도부터 매년 5년 간격으로 우리나라 결핵문제의 크기 및 추세를 파악하기 위해 표본조사통계방법인 전국결핵실태조사를 실시해 왔으며 이어 2000년도에는 인터넷 웹 기반의 전국결핵정보감시체계 구축을 통해 현행 결핵관리체계 안에서 공공의료부문과 민간의료부문을 통합 연계하는 정보수집 및 감시체계를 구축, 새로운 패러다임의 2000년대 결핵관리 정보체계를 개발 실시하고자 한다. 이에 올해 실시되는 전국결핵감시체계에 관해 살펴보고자 한다.

When the definition of income and the equivalence scale was applied just as it was in the LIS (Luxembourg Income Study), the adjusted disposable income inequality calculated by Gini coefficients in Korea was 0.358 for the year 2000. Compare to the 1996 figure of 0.298 the increase of income inequality has skyrocketed. In addition, the adjusted market income inequality increased from 0.302 in 1996 to 0.374 in 2000. The disposable income inequality ranked the third and the market income inequality ranked at the mid level in 2000 among OECD countries. One significant finding in this paper was that the difference between the disposable income inequality and market income inequality in Korea is very small compared to those of other OECD countries. The relative poverty ratio, which is calculated by using 40% of the medium income bracket of the disposable income was calculated at 7.6% in 1996 and 11.5% in 2000. The poverty ratio in 2000 for Korea ranked one of the highest in OECD countries, also.

This paper discusses transformation of the US population census since 1990 and its future prospects by mentioning the 2000 census experience and the 2010 census plans. First, it examines the recommendations written for the 2000 census by the Committee on National Statistics, National Research Council, such as introduction of statistical estimation, response rate improvement, long form improvement, adjustment in differential undercount by race/ethnicity, alternative census methods, collection of small-area statistics in non-census years, and census frame enhancement, and describes how the US Supreme Court decision of 1998 led the Census Bureau to fail in conducting the US version of One Number Census which uses statistical estimation by matching actual enumerations from the Census main survey and post-enumeration survey. Second, it examines one key element of the 2010 U. S. census, say, the separation of long form from short form and describes the main features of American Community Survey, a rolling census which replaces long-form component of the traditional US "Decennial Census" Another element is MAF/TIGER Enhancement Program which aims to improve enumeration accuracy in the traditional short-form census and help the Census Bureau introduce a mobile computer system as part of high-tech census operation. In this paper, it is pointed out that the separation of long form from short form is not an accidental one which results from the US Supreme Court decision, but the Census Bureau at this time in 2008 worries about the accuracy of enumeration because it has failed to develop a mobile computer system and will have to canvass 115 million households by paper and pencil by hiring 600 thousand temporary census workers.

1996년 8월 23일 교육법 시행령의 개정 공포에 따라 수의학 교육의 수업연한이 4년에서 6년으로 연장되고 1998년 10개 수의과대학은 480명의 6년 제의 신입생을 모집하였으며 2004년에 6년 제의 수의학 교육을 받은 첫 졸업생을 배출하게 되었다. 그러므로 수의학교육과 수의사국사고시제도는 선진국 수준으로 개선되어야 한다. 필자는 2000년 9월 28일에 대한수의사회의 주관으로 수의과학회관(성남시 분당)에서 개최된 '수의학교육 및 수의사국가고시제도 개선방안'(신광순, 2000)의 주제에 대한 토의자로 참석하였다. 필자가 이 심포지움에 토의자로 초정된 이유는 필자가 의과대학에서 의학교육에 참여하고 있기 때문에 주제에 대한 발표를 듣고 '의학교육과 의사국가고시제도'와 비교하여 토의하여 달라는 요청에 따른 것입니다. 필자는 이 심포지움의 주제의 발표와 토의가 앞으로 6년 제의 '수의학교육과 수의사국가 고시제도'의 개선에 조금이라도 참고가 되기를 기대하면서 '의학교육과 의사국가고시제도' 및 '학습목표의 활용'방안을 고찰하였습니다.

본 논문에서는 정부에서 추진하고 있는 초고속국가망에서 보안대책을 제도적, 관리적, 기술적 관점에서 분석하고 그에 대한 대책을 제시하였다. 초고속정보통신망사업은 국가정보화를 촉진할 정보인프라 구축에 대한 필요성에 따라 지난 95년부터 추진해온 초고속망구축사업이다. 국가망 구축은 2000년까지 전국 144개 모든 통화권을 고속 대용량 (155Mbps∼5Gbps)의 광케이블로 연결하였으며, 2000년 7월에는 초고속교환(ATM)서비스를 제공하고 있고, 2000년 말 기준으로 초고속국가망을 이용하는 기관은 28,686개이고 이용회선수는 36,357개 회선 서비스를 제공하고 있는 망이다.
