비점오염원은 강우시 지표유출에 의해 유출되기 때문에 발생지점 및 발생량 추정이 어려우며, 이에 대한 처리가 어려운 실정이다. 현재 점오염원의 처리가 어느 정도 달성된 선진국에서는 비점오염원이 가장 중요한 오염원으로 대두되고 있는 실정이다. 따라서 본 연구에서는 비점오염을 분석하기 위해 영산강 유역을 대상으로 SWAT모형을 모의하였다. 지형자료로는 토지피복도와 토양도, 그리고 기상자료로는 강우량, 일사량, 기온, 풍속, 상대습도를 구축하였다. 영산강 유역에 대해 오염총량 관리유역별로 2000년~2008년 까지의 비점오염 부하량을 산정하였다. Because non-point pollution source is outpoured by sunace flow at rainfall, occurrence point and occurrence amount estimation are difficult, and treatment for this is difficult. Advanced nation that processing of present point pollution source reaches about is real condition that non-point pollution source is risen to the most important pollution source. As topography data, land cover and soil map were constructed. and As meteorological data rainfall, solar radiation, temperature, wind speed, and relative humidity were constructed. Until 2000 ~ 2008 year by pollution total amount administration basin non-point pollution loads were calculated in Yeongsangang basin.

<P>Reactive oxygen species (ROS), generated by ionizing radiation, has been implicated in its effect on living tissues. We confirmed the changes in the oxidative stress markers upon irradiation. We characterized the changes in the proteome profile in rat liver after administering irradiation, and the affected proteins were identified by MALDI-TOF-MS and ESI-MS/MS. The identified proteins represent diverse sets of proteins participating in the cellular metabolism. Our results demonstrated that proteomics analysis is a useful method for characterization of a global proteome change caused by ionizing radiation to unravel the molecular mechanisms involved in the cellular responses to ionizing radiation.</P>

전자 부품의 일종인 LSI 패키지의 제조 과정에서 절연·방진·방습 등을 목적으로 수지 몰딩이 널리 사용되고 있는데, 냉각과정에서 금속과 수지의 계면에 접합 잔류열응력이 발생하여 파괴의 원인이 되고 있다. 접합 잔류열응력의 측정에는 X선 회절법등이 사용되지만 측정상의 어려움과 계면단 응력특이성에 대한 해석의 곤란함 때문에 적절한 모델링에 따른 수치해석적 연구가 새로이 주목을 받고 있다. 본 연구에서는 Al/Epoxy를 몰딩 접합한 세가지의 대표적인 계면 형상을 선정하여 계면에서의 잔류열응력을 경계요소 수치 해석 및 스트레인 게이지를 이용한 실험을 통하여 각각 해석하였다. 수치해석과 실험결과는 정상적으로 잘 일치하였으며, 서브 요소를 사용하므로써 계면단 응력 특이성의 해석 정밀도를 향상시킬 수 있었다. 또한 접합 잔류열응력의 해석결과로부터 수직응력에 의한 계면 박리가 예상되고, 피착체의 두께가 증가할수록 응력 특이성이 강하게 나타남을 확인하였다. In general residual stress is measured by X-ray diffraction method but in case of bonding residual thermal stress it is inadequate technique to examine the stress singularity. Therefore Two-dimensional elastic boundary element analyses were carried out to investigate the residual thermal stress and stress singularity of bonding interface in Al/Epoxy. This boundary element results were compared with the strain gauge measurements. The effects of different interface models, sub-elements and adherend thickness are presented and discussed. On the basis of the obtained results, interface delamination causing by normal stress is expected and stress singularity is observed more intensively increasing with adherend thickness. It is concluded that the bonding strength of Al/Epoxy interface can be estimated correctly by taking into account the stress singularity at the edge of the interface.

Backgrounds and Objectives: Vascular dementia is a group of dementing disoders arising from various stroke syndrome. Among these. subcortical ischemic vascular dementia (SIVD) is regarded as a relatively distinct clinical entity. However, MRI patterns of SIVD are not homogenous. In some patients, lacunes are dominant, and in others, subcortical white matter changes are. This study was designed to compare risk factor profiles between SIVD with and without multiple lacunes. Methods: We divided 47 subjects (22 males, mean age. 68 years) recruited from VADAPET (Multicenter Trial For Evaluation Of The Changes In the PET Images Of Subcortical Vascular Dementia Patient) study into two groups one with more than 5 lacunes in deep gray matter (lacune group) and the other with 5 or less(non-lacune group) Clinical characteristics and laboratory findings of two groups were compared. Results: Nineteen of 47 patients (40%) belonged to the lacune group. The lacune and non-lacune groups d d not differ in the following variables: age, hypertension, diabetes mellitus, hyperlipidemia heart disease, history of stroke or TIA, history of trauma or major surgery, family history of hypertension stroke, or dementia, age at diagnosis of dementia, body mass index, white blood cell count, ESR, CRP, fibrinogen, hemoglobin A1C, total cholesterol. LDL cholesterol creatinine, proteinuria, glucosuria, and microhematuria. However, male sex, smoking alcohol. hemoglobin, and HDL cholesterol were possibly associated more with lacune group SIVD than with non-lacune group (p<0 1) Multivariate analyses revealed that smoking, hemoglobin, and HDL cholesterol were independent predictors of SIVD with multiple lacunes Conclusion: Our study suggests that SIVD with multiple lacunes may be significantly different in smoking habits hemoglobin, and HDL cholesterol from SIVD without multiple lacunes.

The subject were 653 male patients with uncomplicated gonorrhea at the VD Clinic of Choong Ku Public Health Center in Seoul from January to November 1985. 653 male patients with uncomplicated gonococcal infection were treated one of the following regimens. Five treatment regimens used were 2, 0 gm spectinomycin single 1M, 4 0 mega unit fortified procain penicillin G+2. 0 gm kanamycin sulfate IM preceded by 1 pgm probenecid PO, 6.0 mega unit fortified procain penicillin G+2 pgm kanamycin sulfate IM preceded by 1. 0 gm probenecid PO, 5, 0 rnega unit aqueous crystaline penicillin+2. 0 gm kanamycin sulfate irn preceded by 1, 0 gm probenecid PO and 9 tablets of cotrimoxazole+ 2. 0 gm kanamycin sulfate IM. There were no significant differences in the incidence of PGU among the five treatment groups. The overall PGU rate was 67.3% 59.2% and 53.6% at 3~5, 7~10 and 14 days after treatment respectively. The incidence of PGU at 7-10 days was not significantly higher than that of at 14 days after treatment. It is suggested that it is best to test PGU at 7 days after treatment. Because the longer one waits, the harder to follow the patients, and in earlier period, post-inflammatory irritation might be too frequent. It is also suggested that at 3 5 days after treatment examination of urethritis might serve to compare the effect of treatment regimens on the incidence of PGU.

Trichomoniasis, a common and sometimes distressing condition in women, is caused by infection of the genitourinary tract by the pathogenic protozoan Trichomonris aginalis(T. vaginalis). Men may also be infected, although frequently without any symptoms, and most cases of trichomoniasis are sexually transmitted. The best evidence for an etiologic role for T. vaginalis is in nongonococcal urethritis(NGU). In epidemiologic studies, T,ginalis has been isolated from 1 to 68 percent in men with NGU. The nurnber of NGU is increasing rapidly than gonorrhea in deeloped nations, and in some developing countries, especially in Korea, In view of the difficulties in findng trichomonads by direct microsco by in men, urine culture and serodiagnosis plays an important role in the diagnostic work. Urine culture, indirect fluorescent antibody test(IFAT) and enzyme-linked immunosorbent assay (ELISA) were used to elecect T.vaginalis in 221 patients with male NGU. These patients visited the VD Clinic of ChoongKu Public Health Center in Seoul from May to August, 1989 and from March, 1990 to December, 1991. The results obtained were as follows.: 1. T. vaginalis was grown from only one of the 221 samples on TPS-1 meida. 2. In 208 NGU patients, there were 10(4.8%) positive reactions on IgG antibody in IFAT. 3. In 208 NGU patient, there were 14(6.7%) positive reactions to IgG antibody in ELISA. 4. No statistical significant correlation was found between then sults of IFAT and ELISA in individual patients. In conclusion, 1. Male trichomoniasis in patients with NGU was detected at a, significantly low rate. Due to the small number of patients in the test, further epidemiologic stidies of trichomoniasis in male NGU patient are necessary. 2. Serologic studies (IFAT and ELISA) have detected sorre trichomoniasis in male patients with NGU. These tests seem to be helpful in the diagnosis of male t-ichomoniasis.
