Since 2003, the National Institute of Environmental Research (NIER) of Korea has been conducting "The monitoring study on exposure level and biomarkers of environmental pollutants" in the Ulsan industrial complex with the goals to establish a surveillance system for residents, to evaluate the health effects associated with chronic exposure to environmental pollutants and to develop the environmental health indicators in Ulsan industrial complex. This program consists of three phases an initial or foundation phase in which the program is developed, made operational and extended to the community, followed by an evaluation and accountability assessment of the surveillance system and finally an improvement in the quality of life and the maintenance of good health for Ulsan residents. In the period 2003 to 2008, the study program developed the surveillance system which will be used for the full-length survey. All participants in this study were contacted at a presentation meeting for residents, introduced to the objectives and protocols of the survey, and asked to participate. Informed consent was obtained from each participant. The study is now underway and includes questionnaires, health examinations and the analysis/collection/banking of bio-sample such as blood and urine. To date 828 subjects have participated and already 588 subjects have been followed up. We are committed to complete health examinations and to arrange storage of biosample for all participants. During the current year, we will analyze metals (Pb in blood and Cd, inorganic As and Hg in urine) in 1,972 samples and VOCs (11 species) and PARs (18 species) in 300 samples (blood sample). Moreover, the summary of the first step and the further preparation of the second step are currently underway. In this article, we introduce the study and its protocols and the distribution and size of the study participants. In conclusion, this survey will be continuously conducted on the established cohort and will enable the identification of relationship between environmental pollutant exposures and the health status of residents in Ulsan industrial complex.

한강의 홍수규모에 따른 인도교수위의 조석영향분석

한강하구 조위가 인도교 지점의 홍수위에 미치는 영향을 NETWORK 모형에 의하여 분석하였다. '90년의 세 홍수와 2,000~20,000CMS 간 8개의 규모별 가상홍수에 대하여 조석영향성분을 계산하였으며, 홍수량이 커질수록 조석영향은 감소됨을 알 수 있었다. 홍수량이 2,000CMS 이하일 경우에는 조석의 영향으로 약 50Cm 이상의 수위상승을 보여주었으나, 홍수예경보 기준홍수위 4.5m (7,000CMS)에서는 약 9cm에 불과하였으며 이 이상의 홍수규모에서 조석 영향은 무시할 수 있을 정도로 작게 계산되었다. The increased water level caused by tidal motion at Indokyo is analyzed by the NETWORK model. The tidal effect is studied for 3 real floods in 1990 and 8 classified hypothetical floods in which the peak discharges are in the range of 2, 000-20, 000CMS. The result of numerical simulation shows that the tidal effect is decreased as the flood is increased. The surged level is 50cm when the flood discharge is 2, 000CMS, showing that its effect is considerable. However it shows only 9cm when the discharge is 7, 000CMS which corresponds to 4.5cm of standard flood level of MOC. Therefore, so it may be possible to neglect the influence of the tidal fluctuation when the peak discharge of a flood is bigger than 7, 000CMS.

개수로 만곡부에서의 중심각 변화에 따른 흐름특성

이종태,윤세의,Lee, Jong Tae,Yoon, Sei Eui 대한토목학회 1987 대한토목학회논문집 Vol.7 No.3

본 연구는 수심이 작은 만곡수호에서 중심각과 저면마찰의 변화에 따른 흐름특성을 분석하기 위하여 만곡부의 중심각이 $30^{\circ}$, $60^{\circ}$, $90^{\circ}$, $120^{\circ}$, $150^{\circ}$, $180^{\circ}$인 수로모형올 선택하였으며, 저면 마찰이 비교적 클 경우(C=30)와 작은 경우(C=60)로 구분하였다. 만곡수로내의 중심각 변화에 따른 수면형, 유속분포 및 유향 등에 관하여 검토하였다. 만곡수로내의 최대수위 발생지점은 중심각에 관계없이 만곡수로 입구로부터 $15^{\circ}$ 하류단면부근의 외측하단에서 발생된다. 저면마찰조건이 최대유속선의 이동경로에 미치는 영향은 만곡수로의 중심각이 약 $150^{\circ}$ 이상인 경우에서 뚜렷하다. 속도수두에 대한 횡방향 수면차의 비는 만곡수로의 중심각이 증가할수록 커지는 경향을 보여 주었다. 중심각에 관계없이 만곡부 시점에서의 유향은 내측으로 종점에서는 외측으로 편기된다. The flow characteristics in the shallow open channel bends are investigated, whose total angles were 30, 60, 90, 120, 150 and 180 in degree, and whose bed frictions were relatively rough(C=30) and smooth(C=60), respectively. The terms analyzed in this study are the water surface profile, the distribution of velocity and the flow direction, relating to the various total angles in the bends. The maximum depth in the bends could be found at the outside section of the location of $15^{\circ}$ local angle from the bend inlet, having no relation to the total angle and bed friction. It is supposed that the path of maximum velocities is especially influenced by the bottom friction when the total angles are bigger than 150 in degree, approximately. The ratio of the superelevation to the velocity head seems to increase as the total angle of the bends increases. The flow direction is skewed to the inner side at the bend inlet, and skewed to the outside at the bend outlet, regardless of their total angles.

지표면유출 해석방법이 도시 유역의 홍수량 산정에 미치는 영향

이종태,윤세의,김정환,Lee, Jong Tae,Yoon, Sei Eui,Kim, Jung Hwan 대한토목학회 1994 대한토목학회논문집 Vol.14 No.5

본 연구는 도시 배수구역에서 지표면유출과 우수로의 홍수추적 과정을 통하여 홍수량을 산정하는데 있어서, 지표면유출 해석방법이 결과치에 미치는 영향을 분석하였다. 지표면유출 해석이론의 비교연구를 위해서는 RUNOFF, ILLUDAS, SBUH, RRL 등의 해석모형들을 사용하였으며, 배수관망내 흐름 해석에는 EXTRAN을 사용하였다. 가상 및 실측 강우, 유출량자료가 있는 유역에 대하여 각각 유출해석을 실시하였다. 각 도시 소배수구역의 유출모형에 의한 결과는 도시홍수량 산정에 상당한 영향을 미치고 있음을 보여주고 있다. 지표면유출 해석 결과치에 가장 큰 영향을 미치는 인자는 도달시간으로 판단되었다. 적용 모형 중 RUN-EX(RUNOFF-EXTRAN) 법이 포장, 비포장유역의 해석에 모두 적합하였으며, 다른 모형들에 비해 실측치에 가장 근사하였다. The effects of the calculation method of surface runoff on the estimation of flood in urban drainage basin were analyzed in this study. In comparing with surface runoff methods. RUNOFF, ILLUDAS, SBUH and RRL were investigated. To route the flow in sewer/conduits EXTRAN was applied. The Kings Creek and Gray Haven drainage basin's measured data of rainfall and runoff were used in comparing the computed results. The results show that the greatest effect factor on surface runoff in urban small area is the concentration time. The results estimated by each model which are composed with EXTRAN show that the scheme for surface runoff gives considerable effect on the flood hydrograph in urban drainage system. RUN-EX method gives the most similar simulation results among the surface runoff models, and is more applicable for paved and unpaved basins than others.

Preoperative evaluation of pulmonary function with spirometry can identify those at increased risk of morbidity and mortality owing to pulmonary complications following pulmonary resections. To assess the correlation between FVC, FEV1.0/FVC, EFE25-57% and MVV, measured preoperatively, and the incidence of pulmonary complications following pulmonary resections, a hundred patients who had pulmonary resections were selected. Patients were divided into two groups postoperatively. In group A, there was no postoperative pulmonary complication, and in group b, there were one or more complications. We compared the results of the preoperative pulmonary function tests of the two groups. The difference of FVC between the two groups was statically significant [p<0.01] and FEV1.0/ FVC [p<0.O01]. The differences of the FEF25-75% and MVV were not significant.

고신뢰성 지상시험지원장비 조기 확보를 위한 시나리오 기반 위성 탑재체 패킷 분석방법

이종태,이기준,Lee, Jong-Tae,Lee, Ki-Jun 대한원격탐사학회 2017 大韓遠隔探査學會誌 Vol.33 No.5

Since satellites, including payloads, are limited in how they can respond to problems after launch, the functionality of the satellite should be verified sufficiently by EGSE (Electrical Ground Support Equipment). In addition, considering the trend that the development period of the satellite is shortening and the development of the EGSE must precede the development of the engineering model of electronic equipment, early securing of EGSE is necessary to comply with the development schedule of the entire satellite. In this paper, we propose a method for early securing highly reliable EGSE by devising a scenario based operating payload packet analyzer, which is a part of the EGSE, through functional modularization and external parameterization, and show the result of applying the implemented payload packet analyzer to real satellite program. 탑재체를 포함한 위성은 발사 이후 문제 발생시 조치할 수 있는 방법이 한정적이므로, 지상시험지원장비를 이용하여 그 기능을 충분히 검증하여야 한다. 또한 위성의 개발기간이 단축되고 있는 추세와 지상시험지원장비의 개발 완료시점이 전장품 엔지니어링 모델 개발완료보다 앞서야 한다는 점을 고려하면, 지상시험지원장비의 조기 확보는 위성 전체의 개발일정 준수를 위해서 반드시 필요하다고 할 수 있다. 본 논문에서는 지상시험지원장비의 일부인 탑재체 패킷 분석장치를 기능별 모듈화와 외부 파라메터화를 통해 시나리오 기반으로 동작할 수 있게 고안하여 고신뢰도의 지상시험지원장비 조기 확보방안을 제시하고, 구현한 장비를 실재 위성 개발사업에 적용한 결과를 보여준다.

Between April 9, 1986 and September 2, 1987, 134 patients underwent open heart surgery with hypothermic cardiopulmonary bypass and cold blood cardioplegia. There were 65 patients[48.5%] of acyanotic congenital cardiac anomalies, 19 patients[14.2%] of cyanotic congenital cardiac anomalies, and 50 patients[37.3%] of acquired heart diseases, which included 49 valvular diseases and 1 myxoma. In 84 congenital cardiac anomalies, 44 patients were male and 40 patients were female ranged in age from 2 years to 57 years. In 50 acquired heart diseases, 18 patients were male and 32 patients were female ranged in age from 10 years to 65 years. The common congenital defects operated were VSD in acyanotic cardiac patients, and Tetralogy of Fallot in cyanotic cardiac patients. Among 50 acquired heart diseases, 49 patient underwent operation for cardiac valvular lesions. 33 patients had mitral valve replacement and 7 patients had aortic valve replacement. 1 patient underwent aortic valvuloplasty and 8 patients had double valve replacement. The operative mortality rate was 3.1%[2 out of 65 patients] in acyanotic cardiac patients, 5.3%[1 out of 17 patients] in cyanotic cardiac patients, and 12.0%[6 out of 50 patients] in acquired cardiac patients, with overall mortality rate of 6.7%[9 out of 134 patients].
