  • 대기 환경중 아황산가스, 먼지와 같은 1차오염물질은 배출량의 감소에 따라 대기중의 농도도 감소하는 반면 오존과 같은 2차오염물질은 점차 증가하는 추세로 대도시 지역의 지표면 오존농도가 환경기준을 초과하는 빈도가 점차 증가하고 있다. (백성옥, 2000) 특히 서울시의 경우는 오존주의보를 발령하는 고농도 오존농도 0.12ppm을 초과한 횟수는 오존주의보를 시행한 이래로 96년 11회, 97년 19회, 98년도 18회, 99년도16회 2000년도엔 22회로 증가하고 있는 추세이다. (중략)

  • Background : Anemia is still the most common nutrient deficiency worldwide, especially in adolescence because of an insufficient supply of iron, an increased iron requirement due to accelerated physical growth and blood loss due to menstruation in girls. This study was designed to assess the anemia and serum iron status of middle school girls. Methods : Hematologic examinations, physical examinations and questionnaires were performed for middle school girls in 1990, 1997, 1999 and 2000. Anemia was defined as a serum hemoglobin level of less than 11.5 g/dL. Iron deficiency was defined as a serum ferritin level of less than 10 ng/mL. Iron deficiency anemia was defined as anemia plus one of the following; MCV less than 78 fL, Ferritin level less than 10 ng/mL or Transferrin saturation rate less than 10%. Results : There was no significant difference in mean Hb between urban and rural areas and decreases in mean Hb as with age. The prevalence of anemia decreased by year; 13.5% in 1990, 6.9 % in 1997, 6.0% in 1999, and 5.7% in 2000. It was high in high school girls(10.1% in 1997 and 12.6% in 2000). The prevalence of iron deficiency decreased by year; 36.1% in 1990, 13.9% in 1997, 13.3% in 1999, and 23.2% in 2000. It was 21.3% in 1997 high school girls and 37.8% in 2000. The prevalence of iron deficiency anemia(IDA) decreased by year; 10.0% in 1990, 4.6% in 1997, 8.3% in 1999, and 6.1% in 2000. It was 11.6% in 1997 high school girls and 18.6% in 2000. Conclusion : Although the prevalence of iron deficiency decreased during this period, the prevalence of anemia in the elder adolescence girls was high. Two things are recommended; first, it is necessary to screen for anemia in middle school girls and high risk groups, second, it is important to evaluate the knowledge of nutrition and to enforce effective nutritional education, leading to subjects receiving adequate nutrition.

  • This study is conducted to know the change in water environment of Lake Hwajinpo from 2000 to 2008 with physico-chemical parameters; salinity, dissolved oxygen, total phosphorus and total nitrogen and others. And zooplanktons and phytoplanktons were studied from 2007 to 2008. From the water quality data of Lake Hwajinpo from 2000 to 200S; water temperature, salinity, transparency, chemical oxygen demand and dissolved oxygen ranges are $2.8{\sim}29.4^{\circ}C$, 0.23~33.2‰, $0.2{\sim}1.8\;m$, $0.2{\sim}20.2\;mg\;L^{-1}$ and $0.1{\sim}17.4\;mg\;L^{-1}$ and the average values are $18.0^{\circ}C$, 15.7‰, 0.7 m, $5.7\;mg\;L^{-1}$ and $8.0\;mg\;L^{-1}$, respectively. Total phosphorus (TP) and total nitrogen (TN) ranges are $0.024{\sim}0.869\;mg\;L^{-1}$ (average 0.091) and $0.240{\sim}5.310\;mg\;L^{-1}$ (average 1.235). Average TN/TP ratio is 16.4. The annual variations in COD, TP, TN and Chl.${\alpha}$ are compared. COD in 2000 is $4.83\;mg\;L^{-1}$ and 2008 is $1.80\;mg\;L^{-1}$ which is reduced by $0.34\;mg\;L^{-1}$ every year. TP in 2000 is $0.07\;mg\;L^{-1}$ and 2008 is $0.05\;mg\;L^{-1}$ reduced gradually. Yearly reduction in TN is $0.09\;mg\;L^{-1}$, in 2000 and 2008 the values are $1.54\;mg\;L^{-1}$ and $0.77\;mg\;L^{-1}$ respectivly. Chl.${\alpha}$ in 2000 is $46.30\;{\mu}g\;L^{-1}$ and $5.78\;{\mu}g\;L^{-1}$ in 2008; yearly reduction is $4.50\;{\mu}g\;L^{-1}$. The tropic state index (TSI) in south and north parts of Lake Hwajinpo in 2000 are 67 and 63 which are reduced to 63 and 59 in 2008 respectively. North and south part of Lake Hwajinpo have 67 species of phytoplankton under 47 families in 2007 and 2008. Dominant species in south part in 2007 are; Asterococcus superbus in May, Lyngbya sp. in September and Trachelomonas spp. in November and in 2008 Anabaena spiroides in August are abundant and varies with time. Zooplankton species in Lake Hwajinpo are 25 of 25 families. Dominant species in south part in May and August 2007 and May and November in 2008 Copepoda larvae and in September 2007 Protozoa spp. of Protozoan and Brachionus plicatilis and Brachionus urceolaris of Cladocera in August 2008. Dominant species in north part Asplanchna sp. of Cladecera in August and November 2007 and rest of the time are larvae of Copepoda. In this way, the water quality of Lake Hwajinpo is changing with slow rate in the long period specially nutrients concentration (TP, TN etc) is decreasing.

  • The objective of this study is to estimate the impacts of land cover change on the runoff behavior using Hydrologic Simulation Program-Fortran (HSPF) model and Landsat images. Land cover maps were prepared using three every ten years from 1980 to 2000 of the upper watershed ($258\;km^2$) of Gyeongan stream. Hydrologic parameters of HSPF were calibrated using observed data (1999 - 2000) and validated using observed data (2001, 2003) at Gyeongan gauge station. The simulation results showed that runoff volume and peak rate increased as $15.0\;km^2$ forest areas decreased and $19.3\;km^2$ urban areas increased for 20 years land use changes. The runoff volume showed a higher rate of increase in wet year (2003, 1709.4 mm) than in dry year (2001, 871.2 mm). The peak runoff increased $13.3\;\%$ in normal year (2000, 1257.3 mm) because the year has the highest rain intensity (241.3 mm/hr) among the test years. The runoff volume of a dry season and a wet season (May - September) in normal year 2000 increased $4.4\;\%$ and decreased $8.1\;\%$, respectively.

  • 최근의 폭발적인 인터넷 사용의 증가와 또 그것과 유사한 품질의 서비스를 이동중에도 제공 받고자 하는 사용자의 요구와 음성통화 시장의 포화에 따라 무선 데이터 시장을 새로운 돌파구로 보는 제조업체 및 서비스 제공자의 노력으로 IMT-2000 서비스가 이미 진행되고 있다. 비록 2세대 디지털 셀룰러에서 IMT-2000으로의 진화가 현재 지지부진하지만, 2010년경의 데이터 사용량 예측을 참고로 할 때 새로운 시스템의 출현이 필연적이다. ITU-R SG8에서는 1999년 말까지 초기 IMT-2000 시스템에 대한 표준화 작업을 수행해왔던 TG8/1을 해체하고 2000년 이후의 위성 및 지상 부분 모두를 포함한 IMT-2000의 발전과IMT-2000 이후 시스템에 대한 비전과 목적의 정립을 위해 SG8 산하에 WP8F를 조직하여 활발하게 연구하고 있다. 본 고에서는 IMT-2000의 비전 표준화를 중심으로 하여 WP8F의 주요 표준화 동향을 살펴본다. 아울러 WP8F의 유관 기관의 활동도 함께 기술한다.

  • Purpose: To report on the changes in the patterns of care and survival over time for esthesioneuroblastoma. Materials and Methods: We retrospectively analyzed 42 previously untreated and histologically confirmed esthesioneuroblastoma patients seen between March 1989 and June 2007. According to Kadish's classification, 3 patients (7%) were stage A, 6 (14%) at stage B, and 33 (79%) at stage C. Of the 33 Kadish C patients, 19 and 14 patients were treated from 1989 through 2000 and from 2001 through 2007, respectively. Treatment included surgical resection, radiotherapy, chemotherapy, or a combination of these methods. Chemotherapy was administered to 8 of 19 patients (42%) seen from 1989 through 2000, whereas all of the 14 patients seen from 2001 through 2007 received chemotherapy (p<0.001). No patient was treated by three-dimensional conformal radiotherapy (3D-CRT) from 1989 through 2000, however 8 of 14 patients (67%) seen from 2001 through 2007 underwent 3D-CRT (p<0.001). The median follow-up time for surviving patients was 6.5 years (range, 2.2~15.8 years). Results: The 5-year overall survival (OS) and progression-free survival (PFS) rates for the entire cohort were 53% and 39%, respectively. The 5-year OS was 100% for Kadish stages A or B and 39% for stage C (p=0.007). For patients with stage C disease who were treated from 1989 to 2000 and from 2001 to 2007, the 5-year OS rate was 26% and 59% (p=0.029), respectively and the corresponding 5-year PFS rate was 16% and 46% (p=0.001), respectively. Intraorbital extension and treatment era (1989~2000 vs. 2001~2007) were found as independent factors for OS and PFS in a multivariate analyses. Conclusion: The results of this study suggest that treatment era, which features a distinction in treatment modality and technique with the introduction of 3D-CRT, may be the cause of improved OS and PFS in Kadish stage C patients. To achieve better outcomes for patients with Kadish stage C, combined chemoradiotherapy, especially 3D-CRT, is recommended in addition to surgery.
