충청남도 천안시에 위치한 천안천을 대상으로 상류에서 하류까지 3개 정점에 대하여 2009년 4월에 부착규조류 군집과 생물학적 수질평가(Biological water quality)를 실시하였다. 천안천의 부착규조류는 총 30분류군이 출현하였으며, 대부분 Navicula와 Nitzschia 속에 속하는 분류군으로서 유기오염 선호종(Saprophilous species)들이 출현하였다. 우점좀과 아우점종으로는 Nitzschia palea와 Navicula pupula가 모든 정점에서 출현하였으며, 약 50%의 높은 우점율을 나타냈다. 생물학적 수질평가는 상류에서 하류까지 α중부수성(α-mesosaprobic) 에서 β중부수성(β-mesosaprobic)으로 천안천은 유입 유역으로부터 심한 오염부하를 받는것으로 판단된다. This research was to assess the biological water quality and epilithic diatoms community from 3 sites in Cheonan-stream located at Cheonan, Chungcheongnam-do on April 2009. As a result, total of 30 taxa of diatoms appeared. Most taxa found were Saporophilous species such as Navicula and Nitzschia. Dominant species and subdominant species, Nitzschia palea and Navicula pupula appeared in all sites showing high relative frequency of about 50%. As a result of the biological water quality assessment, Cheonan-stream was found to be alpha mesosaprobic to beta mesosaprobic from upstream to downstream, receiving pollutant load from the basin.

This study investigates the influence of cane length on the weight distribution of the elderly in a standing position. Thirsty participants were evaluated using two different cane lengths based on measurements of distal wrist crease to ground (WC cane), and distance of greater trochanter to ground (GT cane). A limloader was used to determine the weight distribution on the subject. It was found that 6.5% of body weight was supported on a GT cane and 7.7% of body weight supported on a WC cane in a standing position. Results suggests that more weight is distributed on a WC cane than a GT cane in the elderly.

The excessive initial corrosion rate of Mg is a critical limitation in the clinical application of biodegradable Mg implantsbecause the device loses its fi xation strength before the fractured bone heals. This study suggests a new approach to overcomethis hurdle by accelerating tissue regeneration instead of delaying the implant biodegradation. As angiogenesis is anessential process in early bone regeneration, a Mg implant coated with electrospun nanofi bers containing nitric oxide (NO),which physiologically promotes angiogenesis, is designed. The integrated device enables adjustable amounts of NO to bestored on the NO donor-conjugated nanofi ber coating, stably delivered, and released to the fractured bone tissue near theimplanted sites. An in vitro corrosion test reveals no adverse eff ect of the released NO on the corrosion behavior of the Mgimplant. Simultaneously, the optimal concentration level of NO released from the implant signifi cantly enhances tube networkformation of human umbilical vein endothelial cells without any cytotoxicity problem. This indicates that angiogenesis canbe accelerated by combining NO-releasing nanofi bers with a Mg implant. With its proven feasibility, the proposed approachcould be a novel solution for the initial stability problem of biodegradable Mg implants, leading to successful bone fi xation.

본 연구에서는 축냉재로서 에너지의 합리적 이용을 위한 건물공조용 축냉시스템에 적용이 가능한 TMA-물계 포접화합물의 농도와 충전량의 변화에 따른 상변화온도, 비열 및 과냉도를 실험을 통하여 다음과 같은 결론을 얻었다. (1) 냉열원온도 -5。C에서 상변화온도는 5.4。C 이상으로서 적절함을 확인하였다. (2) 상변화온도는 충전량이 많을수록 높아지는 것을 확인하였다. 위의 실험결과로부터 TMA-포접화합물은 건물공조용 축냉재로서의 열물성을 갖는다고 판단된다. The objective of this paper is to investigate the thermal properties of TMA-clathrate compound applicable to cold storage system for residential air-conditioning in order to use energy reasonably. Especially, the test tube experiments are performed to compare and analyze the concentration of TMA-clathrate compound, the temperature of heat source, and the phase change temperature, specific heat and subcooling characteristics according to the variation of charge capacity. The result are summarized as follows:1) -5。C is proper as the temperature of heat source because the temperature of phase change is above 5.4。C, 2) the phase change temperature appears higher as the charge capacity is larger. Thus, it appears that TMA-clathrate compound has thermal properties as the cold storage medium for residential air-conditioning.

Renal papillary necrosis occurs most commonly in association with urinary tract infection, diabetes mellitus, sickle cell disease, vascular disease, and analgesic nephropathy. Clinical presentation may be related to symptoms of pyelonephritis such as flank pain, renal colic, hematuria, Proteinuria, recurrent fever. The necrotic tissue may be sloughed off, and the diagnosis can sometimes be made by finding piece of renal medullary tissue in the urine. Pyelography may demonstrate cavities and sinuses in the resion of papillae. Anuria & oliguria can lead to the acute renal failure, and especially prognosis and progress may be affect influenced by urinary infection. We report a case of renal papillary necrosis with ingestion of bear gallbladder. On pyelography, Persistent contrast is diagnostic clue of renal papillary necrosis. This case is not be related to urinary tract infection, but occurred acute renal failure. Expectant treatment was gone.

The effects of alkali treatment to fly ash powder coming in to being artificial zeolite were soil chemical investigated by amount of treat and during on days There was no significant difference in chemical properties between artificial zeolite and particle artificial zeolite. pH and EC value in treatments soils were high known by application with fly ash and artificial zeolite of amount increased. The amount of Av.P_(2)O_(5) adsorption capacity with artificial zeolite known higher than fly ash. In the case of amount of Ex-K, Ca, Mg were detect range between artificial zeolite and particle artificial zeolite. Artificial zeolite application with treatments in soils showed being contrary to each NH_(4)-N other NO_(3)-N for content therefore it is clear that application of particle artificial zeolite product should be more effective than of the artificial zeolite powder for soil condition.
