A 4 years old, mixed male dog with a history of traffic accident was presented to the Veterinary Medical Teaching Hospital of Chungnam National University with tachypnea and respiratory distress. Physical examination showed that the dog was auscultated crackles sounds, dysynchronous abdominal breathing pattern, hemoptysis, hematuria, urodynia and right and left scleral congestion. Blood and blood chemical examination revealed that WBC, AST and ALT was highly elevated. Parenchymal pulmonary fluid and closed pneumothorax were observed by thoracic radiography. This case was diagnosed as pulmonary contusion. Intravenous fluid and oxygen was administered and also dexamethasone(1mg/kg, Ⅳ), furosemide(2mg/kg, Ⅳ), (ampicillin, 20mg/kg, Ⅳ) and meloxicam(0.2mg/kg, PO) were intravenously injected for 5 days. Abnormal clinical signs were disappeared after treatment.

Auto exhausts and air pollution can become trapped in the cabin of vehicle, reducing the amount of oxygen available for breathing. Driver may feel sleepy, headaches, nausea, confusion, dizziness and lower levels of oxygen can damage the driver's general health. Consequently, oxygen generator purified oxygen into the car to help driver get the oxygen driver's body needs. In this study, in order to evaluate the oxygen generator performance, the samples that the various conditions(humidity(50%, 100%), flow and oxygen concentration) were examined. There were three types of oxygen generator; sample 1(2.5ℓ/min, 36%0₂), sample 2(4.5ℓ/min, 41%0₂) and sample 3(5ℓ/min, 39%0₂). As the humidity increased from 50% to 100%, the oxygen concentration of the sample 1(36%), 2(41%) and 3(39%) was reduced 31%0₂, 38%0₂ and 38%0₂, respectively. Also, the each sample measured that effect of human in car on oxygen concentration, if the oxygen concentration is one person in car, each sample of oxygen concentration was 20.8%0₂, 23.7%0₂ and 21.2%0₂. From the above results, it was shown that oxygen generator for car, if the oxygen concentration is increased, effect of humidity is reduced, and that in the sample of supplying a high-rate of oxygen, the oxygen concentration is increased. It was suggested that effect of humidity on oxygen generator for car can be reduced according to the supply of oxygen.

A 6 years old Schunauzer dog (7.2kg, intact female) with history of hematuria for two days was referred to the Veterinary Medical Teaching Hospital of Chungnam National University. Complete blood cell count showed no significant abnormalities and serum chemistry profile showed increased phosphate profile. On urinanalysis, there was evidence of bacterial infection. On ultrasonographic evaluation, irregular renal contour and increased echogenecity, pelvic and uretral dilation, and thickening of urinary bladder wall were observed. Based on these finding, the dog was diagnosed as pyelonephritis. The dog was treated with antibiotics based on antimicrobial susceptibility test results, then successfully resolved after 8 weeks of treatment.

친수성으로 표면개질한 폴리설폰막의 투과플럭스

송근호,김강희,조성헌,이광래,임종호,배성수 한국화학공학회 2004 Korean Chemical Engineering Research(HWAHAK KONGHA Vol.42 No.1

실관막형 폴리설폰 막의 표면을 2-hydroxyethylmethacrylate(HEMA)로 코팅하였으며, 코팅인자들인 azobisisobutyronitrile(AIBN)/HEMA 성분비, 용매의 종류(물, 메탄올), UV 조사시간 등이 투과플럭스에 미치는 영향을 조사하였다. AIBN/HEMA/ 메탄온ㄹ 용액으로 코팅한 막이 AIBN/HEMA 성분비가 높고, UV 조사시간이 길수록 투과플럭스가 높았다. AIBN/HEMA 성분비가 낮으면 동일한 투과플럭스를 얻기 위하여 UV조사시간을 더 길게 하여야 하며, 특정한 AIBN/HEMA 성분비와 UV 조사시간에서 코팅한 막의 투과플럭스는 원래의 막(코팅하지 않은 막)보다 높게 나타났다. 또한, 오일에멀젼에 의한 fouling은 코팅한 막과 원래의 막에 모두 나타났지만, 코팅한 막의 fouling이 원래의 막 보다 현저히 낮았다. 즉, fouling 발생 후 코팅한 막의 수투과 플럭스(0.2683g/㎠ㆍmin)는 코팅하지 않은 막(0..448g/㎠ㆍmin)보다 약 6배 이상으로 높게 유지되었다. A hollow-fiber type polysulfone UF membrane was surface-coated with 2-hydroxyethylmethacrylate(HEMA). The effect of various coating paramters on permeation flux was investigated, such as concentration ratio of Azobisisobutyronitrile(AIBN)/HEMA, solvent (water or methanol), and UV irradiation time. The membrane coated with a solution of AIBN/HEMA/methanol showed about 2.65 times higher water flux than that coated with a solution of AIBN/HEMA/water. The membrane coated with a solution of higher AIBN/HEMA ratio and a longer UV irradiation time exhibited a higher permeation flux. The membrane coated with a solution of lower AIBN/HEMA ratio needed a longer UV irradiation time for coating to get a same level of permeation flux. In order to have a greater permeation flux than uncoated membrane, the membrane should be coated with a solution of a certain AIBN/HEMA ratio and UV irradiation time. The fouling by oil emulsion occurred to both of the coated and the uncoated membrane. However, the fouling of coated membrane was much less than uncoated one; the water flux(0.2683g/㎠·min)through the coated membrane was about 6 times higher than that(0.0558g/㎠·min) through the uncoated membrane.

Generally PbTiO3 if manufactured in a form of thin films which is useful for the application infrared sensors and non-volatile memory devices. Moreover PbTiO3 has a characteristic of adsorption for organic acid as well as electronic property. Organic acid adsorption properties of PbTiO3 powder prepared by sol-gel method was compared with the powder purchased from Aldrich Co. Crystallization and particle size of PbTiO3 are influenced by process variable, such as dilution of sol solution, catalysis, calcination temperature, calcination time, etc. As the size of PbTiO3 power decreased until several nanometers, adsorption of acetic acid and formic acid was increased 1.5-fold and 1.2-fold respectively

강건호,오양훈,송왕철 濟州大學校 産業技術硏究所 1998 산업기술연구소논문집 Vol.9 No.2

The internet enables multivendor computer systems to join together so that many different models of network devices can co-exist with one another. These days a management program for a web-based SNMP network device is being developed by using web techniques such as HTML. Java Applet. etc. This paper proposes a user interface technique for managing a web-based network to provide static, dynamic, and interactive management information. Hence, the implementation of the user interface using the web-based technique of Java Applet. makes it possible for a manager to easily search and manage agent MIBs through a browser.
