Background and Objectives: We previously reported that, compared with standard cardiopulmonary resuscitation(S-CPR), better hemodynamic effects could be achieved by simultaneous sterno-thoracic cardiopulmonary resuscitation(SST-CPR) in which we compressed the sternum and constricted the thorax circumferentially during the systolic period by using a device. This study was designed to assess whether SST-CPR, compared with S-CPR, improve the survival rate of dogs with cardiac arrest. Subjects and methods: Twenty-five mongrel dogs(19∼31㎏) were enrolled in this study. After four minutes of ventricular fibrillation induced by an AC current, animals were randomized to resuscitate with either S-CPR(n=13) or SST-CPR(n=12). Epinephrine(1 ㎎) was injected into the right atrium every three minutes after the beginning of CPR. Defibrillation was attempted after 6 minutes of CPR. Standard advanced cardiac life support was started if defibrillation was not successful. Results: SST-CPR resulted in significantly(p<0.001) higher systolic arterial pressure(91±47 vs 47±24 ㎜ Hg), diastolic pressure(43±24 vs 17±10 ㎜ Hg), coronary perfusion pressure(35±25 vs 13±9㎜ Hg), and end tidal CO2 tension(9±4 vs 3±2 ㎜ Hg). Two of 13 animals(15 %) resuscitated with S-CPR and six of 12 animals(50%) resuscitated with SST-CPR survived until 12 hours after cardiac arrest(p<0.05). Donclusion: SST-CPR, compared with S-CPR, improves the short-term survival rate in canine cardiac arrest.

본 연구는 연안 어장의 수질 개선 및 양식 환경 개선을 위하여 준설퇴적물을 환경친화적으로 처리하는 방안을 모색하기 위한 실험으로써 준설퇴적물의 유기물 분별정량을 통한 최대 분해율 선정, 예비안정화 시험, 준설퇴적물 희석배율별 안정화 특성 평가 등을 수해하였다. 유기물 분별정량 결과 준설퇴적물의 유기물 분해율 30~40%를 안정화의 지표로 얻을 수 있었고 희석배율별로 측정한 TCOD, SCOD 역시 32%와 83%의 제거율을 보여 충분한 안정화가 진행된 것으로 나타났다. 또한 안정화 처리 전ㆍ후 준설퇴적물의 실제 안정성평가를 위해 발아시험을 실시해 본 결과 유기물의 안정화 처리를 거칠 경우 준설퇴적물의 식물 독성이 저감됨을 알 수 있었다. It was attempted to treat organic matter in the dredged sediments from costal mari-culture site eco-friendly. Carbohydrates in the dredged sediment were fractionated, and the potential of oxygen consumption was estimated. 30-40% of organic matter found to be maximum degradable content in a biological treatment. Easily degradable organic matter was removed in the aerobic batch test, and the sediment sample was gradually stabilized. 32% of TCOD and 83% of SCOD was removed in this experiment. TCOD removal of 32% was in the range of maximum degradable content for organic matter (30-40%). Seed germination test was conducted for the sediment samples before and after the biological stabilization, and it was found that phyto-toxicity was substantially reduced by the stabilization process.

A model for off-site radiological dose evaluation due to liquid effluents generated from the operation of nuclear facilities, which are located in inland area, was developed in consideration of Korean agricultural and environmental conditions. In addition, sensitivity analysis was performed for the improvement of the model. Using the developed model, test runs for nuclear fuel fabrication facilities were conducted. Five kinds of exposure pathways(vegetation, animal products, drinking water, fresh-water-fish, shoreline deposits) and two kinds of radionuclides(234U, 234Th) were considered. Sensitivity analysis for input parameters of the model was conducted by applying a Monte Carlo method with Latin Hypercube Sampling (LHS) technique. As the results, the ingestion of irrigated agricultural products was the highest contributor among the considered exposure pathways. Major sensitive input parameters for the results were the ratio of the interception fraction to the yield of agricultural plants and the human consumption rate.

돌나물(Sedum sarmentosum Bunge)의 자생지 서식환경과 생장특성에 관한 연구

이중기,황재문 안동대학교 농업과학기술연구소 2000 農業科學技術 硏究論文集 Vol.7 No.-

돌나물(Sedum sarmentosum)은 산 또는 들에 널리 분포하며, 특히 경사지나 바위 위에서도 이끼류와 공생하고 있었다. 자생지 토양은 수분함량의 범위가 넓었고 유기들이나 치환성 양이온 등의 함량은 재배작물의 평균치와 비슷한 수준이었다 돌나물은 월동 후 2월말부터 싹을 틔우며, 3월초부터 성장하여 5월 중순에 채취할 정도(약 30cm)로 자란다. 5월 중순에 줄기의 5∼6마디에서 1∼4차례 꽃가지가 갈라져 노란색 꽃을 피우며, 11월말부터 생장이 정지되어 잎이 말라 떨어지고 줄기와 뿌리가 일부 남아 월동한다. 돌나물은 25℃에서 생육 상태가 가장 양호하였고 생장량도 많았다. 그리고 자연광의 50%차광처리에서 생체중이 가장 높았고 자연광에서보다 개화도 10여일 지연되었다. 토양수분의 함량이 22%±1.0정도(1일 관수량 1.5mm 수준)에서 생체량이 가장 많았으나 자생지 들나물에 비해 절간장이 길었으며, 12%±1.0(1일 관수량 1.0mm 수준)에서 상품가치가 양호하였다. This study was conducted to survey the habitat environment at natives of Sedum sarmentosum and to elucidate growing conditions of S. sarmentosum. In native areas of S. sarmentosum, Digitaria microbachne, Artermisia mongolica and mosses were dominant species and S. sarmentosum grown on the slope and rock fences symbiosed with mosses. S. sarmentosum might lave wide adaptability on the dry or wet soil and sunny or shaded place. The organic content of the habitat soil was almost same level of the average upland soil, but the available phosporous and calcium content were low level. The growth stage was different by topography of S. sarmentosum. This plant was sprouted from late Febuary, grown continuously until mid of May, then formed flowering branches, flowered from late May and stopped growth in early November. The optimum growth temperature of S. sarmentosum seemed to be about 25℃, however, it showed slow growth even at 1.5℃. The shading 30 to 50 % of natural sun light was good for growth but delayed the flowering time compared to the natural condition, and the wet soil(irrigatiing 1.5mm a day) resulted more vigorous growth than dry conditions(irrigating below 1.0mm a day) in S. sarmentosum.

Background: The aim of this study was to determine whether the conventional subcostal approach is suitable for emergency pericardiocentesis in patients with cardiac tamponade or impending cardiac tamponade. Methods: This study was a prospective, observational study conducted at the emergency department of a tertiary hospital, Patients who had symptomatic pericardial effusion and who needed emergency pericardiocentesis in the emergency department were included in this study. We measured the epicardium-to-pericardium distance at the subcostal, parasternal, and apical area with two-dimensional echocardiography to determine the appropriate puncture site for pericardiocentesis. An epicardium-to-pericardium distance of more than 1.0 cm was considered as the primary safety factor in determining the Puncture site for pericardiocentesis. The skin-to-pericardium distance was considered as secondary safety factor. Results: Ninety-five consecutive patients(55 males and 40 females; total mean age: 53 year old) with cardiac tamponade or impending cardiac tamponade were enrolled in this study. The puncture site for pericardiocentesis, as determined by echocardiography, was the subcostal area in 43 patients(45%), the apical area in 40 patients(42%), the left parasternal area In 11 patients(12%), and the right parastemal area in one patient(1%). Pericardiocentesis failed in 2 patients(2%) with the subcostal approach and in one patient(1%) with the apical approach. The average epicardium-to-pericardium distance was 31 ±21 mm in patients with the subcostal approach and 21±8 mm in patients with other approaches. There were no differences in the amount of pericardial fluid and in the intraperical pressure among patient groups according to puncture site. There were two procedure related complications: a puncture of the right ventricle with the subcostal approach and a ventricular tachycardia with the apical approach.
