The gate expansion was planed to increase discharge capacity of gate structure at sea dike in Asan Bay. So it was estimated for changing of hydraulic states in Pyeongteak Harbor Zone caused by gate expansion, using Delft3D, FLOW-3D and hydraulic physical scale model testing. In result, the influence of gate expansion was indicated to be weak.

아산항은 초기에는 인천항의 보조항으로써 수도권 공단을 지원하는 공업항으로 개발하고, 최종적으로는 수도권의 제 2 관문항으로써, 서해 중부를 대상으로 중추 항만의 기능을 가질 수 있도록 개발 방향이 설정되어 있다. 아산항 배후의 세력권은 아산만으로부터 반경 30 - 40km 내 지역인 경기 남부의 충남ㆍ북부 일부와 수도권이 포함되어 있다. (중략)

미래는 스피드 시대다. 일찍 일어나는 새가 먹이를 많이 잡듯 빠르게 움직여야 더 많은 것을 얻을 수 있다. 아산신도시가 속도를 내기 시작했다. 천안아산역 고속철도(KTX)가 개통되면서 아산신도시는 이미 많은 변화가 예상된다. 아산 탕정산업단지 등 개발 호재를 등지고 고속철도와 함께 출발한 아산신도시를 둘러보자.

We will present various MR findings of hyperacute ischemic stroke with our own experiences in the management of the patients according to the findings. 대상 및 방법： A total of 441 patients were underwent 'acute stroke MR' imaging protocol between Mar. 2001 and Jun. 2003. The protocol included initial T2-weighted image (WI), diffusion WI (DWI, b=2000), time-of-flight (TOF) MR angiography (MRA), and pefusion WI(PWI), and follow-up T2WI, DWI, TOF MRA, and neck vessel contrast-enhanced MRA obtained three to five days after the insult. Among them, we retrospectively reviewed the MR findings and clinical courses of 193 patients with anterior circulation territorial infarction. Those ICA and MCA lesions were divided into six and five groups respectively according to the level and mechanism of the occlusion. PWI findings can be another factor in the management planning.

This study analyzes a general pattern of the gate operation at the Asan bay seadikes and its effects on salinity. The coefficient of determination between precipitation and released freshwater from gate operation turns out to be 0.77-0.89. A stratification is not shown in the analysis of the salinity in upper and lower layers at the Asan bay because of strong tidal effects, and the coefficient of determination between runoff and salinity is in the range of 0.49-0.62 except station Daesan 4. Salinity observations from 8 stations show mean and standard deviation are highly correlated (coefficient of determination=0.9936), and both mean and standard deviation are influenced by freshwater. Eventually it is found that stations Asan 2 to 4 and Daesan 1 are within the regions of the freshwater influences.

Geographic Information System (GIS) combined with Universal Soil Loss Equation (USLE) was used to estimate the soil erosion of Asan Bay experiment watershed in Korea. Spatial data for each USLE factors were obtained from the Landsat-5 TM remote sensing images and 1/25,000 scale digital contour maps. Sediment yield to Asan Bay was estimated by the sediment delivery ratio and trap efficiency. The estimated sediment yield was compared with observed on the Asan and Sapgyo estuary sub-watershed within Asan Bay experimental watershed for the period from 1981 to 2000. The calculated total annual sediment yields from Asan and Sapgyo estuary sub-watershed to Asan Bay were 5,665tonnes/yr and 6,766tonnes/yr, respectively. The measured sediment yields were 12,937tonnes/yr and 12,395tonnes/yr, respectively on an average.

Purpose: This study was done to provide effective nursing interventions using an individualized educational program designed to contribute to the knowledge, compliance and physiologic parameters (serum potassium, phosphorus and interdialytic weight gain) of non-compliant hemodialysis patients. Methods: There were 22 participants in the experimental group and 19 in the control group. Nurses with rapport with patients provided education to non-compliant hemodialysis patients for 20 minutes three times a week for six weeks. This education program consisted of individual consulting, telephones conversations regarding hemodialysis, and requests for patient support from patients' families and colleagues. Results: Hypothesis 1; "Knowledge about hemodialysis in the experimental group will be higher than the control. group" was not supported. Hypothesis 2; "Compliance will be higher in the experimental group than in the control group", and Hypothesis 3; "Physiologic parameters of experimental group will improve" were supported as serum potassium and interdialytic weight gain decreased, but results were not consistent for phosphorous. Conclusion: This program for non-compliant patients increased compliance and improved physiologic parameters. Therefore, this educational program should be effective as a nursing intervention.

한반도 중부 서해안에 위치하고 있는 아산만은 서해안 개발사업의 일판으로 각종 개발 계획이 활발히 추진되고 있다. 이러한 해양개발에 따른 대규모의 매입과 준설은 기존의 해수유동 체계를 크게 변화시킬 것으로 예상된다. 본 연구는 아산만의 각종 개발사업과 관련하여 조석, 조류, 조량 등의 수리학적 변화를 예측, 제시하기 위해 수행하였으며, 특히 홍수시 만 내측의 아산호와 삽교호로부터 유입되는 담수에 의한 수위상승 및 유속증가 등과 같은 수리학적 악영향에 대해서도 검토하였다. (중략)

The long-term water-quality change of Asan Bay by the influx of polluted disposal water was predicted through a simulation with an Eco-hydrodynamic model. Eco-hydrodynamic model is composed of a multi-level hydrodynamic model to simulate the water flow and an ecosystem model to simulate water quality. The water quality simulation revealed that the COD(Chemical Oxygen Demand), dissolved inorganic nitrogen(DIN) and dissolved inorganic phosphorus(DIP) are increased at 5 stations for the subsequent 6 months after the influx of the effluent. COD, DIN and DIP showed gradual decreases in concentration during the period of one to two years after the increase of last 6 months and reached steady state for next three to ten years. Concentration levels of COD, DIN, and DIP showed the increase by the ranges of $11{\sim}67%$, $10{\sim}67%$, and $0.5{\sim}7%$, respectively, which represents that the COD and DIN are the most prevalent pollutants among substances in the effluent through the sewage treatment plant. The current water quality of Asan Bay based on the observed COD, TN and TP concentrations ranks into the class II of the Korean standards for marine water quality but the water quality would deteriorate into class III in case that the disposal water by the sewage plant is discharged into the Bay.

Purpose: Head-up position during sleep is one of the non-pharmacologic interventions for the treatment of orthostatic hypotension. Because the head-up position causes discomfort in many patients, this approach may not be acceptable to all patients. We compared the systolic blood pressure in erect position, orthostatic hypotension, orthostatic disability score, and the improvement rates of orthostatic hypotension between the 20 cm head-up group and the 10 cm head-up group. Methods: A control pre/post-test design was used. Between August 1, 2009 and November 15, 2010, we consecutively enrolled patients who showed orthostatic hypotension in patients with Parkinsonian disorders. Sixty-seven patients were prospectively enrolled and forty-four patients were completed the study. Results: There were no statistically significant differences found in the systolic blood pressure in erect position, orthostatic hypotension, and orthostatic disability scores between the two groups. However, five patients showed improvement in 20 cm head-up group and one patient was showed improvement in 10 cm head-up Group. Conclusion: Orthostatic hypotension is decreased with 20 cm head-up position in some patients with Parkinsonian disorders (p=.034). Further research investigating the relationships between orthostatic hypotension and head-up position are warranted.
