A ten months old, female Yorkshire terrier weighing 2.88 kg referred to veterinary teaching hospital of college of veterinary medicine, Konkuk University because of syncope, cough and dyspnea. First hematological and serum chemical test revealed thrombocytopenia, mild anemia, and increase of concentration of ALP (195 U/L). On 57 days later, second hematological and serum chemical test revealed polycythemia, increase of concentration of ALP (211 U/L), and Tchol (387 mg/dl). Right atrium enlargement, main pulmonary artery bulge and cardiomegaly (VHS = 11.5) were observed in radiographic findings. Ultrasonographic images showed both right and left ventricular dilation and turbulent flow between the descending aorta and the main pulmonary artery in color Doppler imaging. ECG showed left ventricular enlargement, SA block, and electrical alternant. Thoracotomy was performed through left fourth intercostal incision under isoflurane anesthesia. Patent ductus arteriosus was double ligated with 1-0 silk. Cough and dyspnea disappeared on 5 days after operation. Turbulent flow was not found in color doppler imaging of ultrasonography on 10 days after operation. Ten months later after the operation, syncope could not exist any more.

The incidence of aseptic meningitis infection is ensuing and threatening the health of children. Enteroviruses are the major agents of aseptic meningitis and identification of virus has been a clue to diagnosis and epidemiology. The outbreak of aseptic meningitis occurred in Pusan, 1998. Patients were concentrated from April through November. Children were more susceptible than adults. Among 306 cases of specimens from stool, throat swab tested, only 7.2% were positive on virus isolation, 12 cases from stool and 10 from throat, respectively. All isolated 7 serotypes of viruses represented cytopathic effect on cultured cells. Three types of echovirus 6, 25, 30 and coxsackievirus B2, B3, B4, B6 were identified by neutralizing anti body test. Isolated coxsackievirus and echovirus were observed by an electron microscope with negative staining.

Background : Mortality from paraquat intoxication depends upon plasma paraquat concentration. To know the severity of paraquat intoxication is important for directing therapeutic modality and predicting prognosis. Sodium dithionite test for urinary paraquat provides an easy and simple method to determine the severity of paraquat intoxication in emergency department. purpose : To determine whether the result urinary paraquat test by sodium dithionite can predict outcome in patients with paraquat intoxication in emergency department. Subjects : 48 patients(male 31, female 17, mean age 37 years) who had exposure to paraquat and presented within 24 hours after exposure. Result : Thirty five patients were positive in paraquat urine test and thirteen patients were negative. Clinical manifestations were more severe in positive patients than in negatives. Complication was much more in positives than in negatives. 28 of 35 patients(80%) in positives and 2 of 13 patients(15%) in negatives died. Conclusion : Positive test for urinary paraquat is associated with high mortality and morbidity from paraquat intoxication, and qualitative test for urinary paraquat by sodium dithionite is an useful method to determine the severity of paraquat intoxication in emergency department.

윤종학,여만구,김동성,이호영 서울産業大學校 1995 논문집 Vol.42 No.1

This study is focused on the prediction of an appropriate tool life by clarifying the correlation between progressive tool wear and signals, when cutting SM45C by end mill in machining center. First of all, end mill have a problem that position of sensor sticking because it is revolution tool, I think that it can be gained specific character according to sticking sensor in the vise. Consequently, the following results have obtained: 1. Each cutting speed of feed rate over 0.1mm had a tendency to increase linearly according to the RMS. 2. The level of AE signal at the same cutting area was more sensitive to depth of cut than the variation of feed rate. 3. In the range of cutting during about 75min at cutting speed 27m/min flank wear turns up about 0.21mm, about 0.29mm in the case of about 65min at 33m/min, hereby RMS increased rapidly at 0.2mm flank wear, also AE-HIT and CUM-CNTS.

PIV의 수리학 분야에의 적용

윤병만,유권규,노영신 명지대학교 산업기술연구소 2001 産業技術硏究所論文集 Vol.20 No.-

This paper introduces PIV technique which can be used for velocity measurement in hydraulic engineering field. Some examples are presented : measurement of surface velocity using LSPIV ; measurement of flow characteristics and fall-velocity measurement using PTV. Results show that PIV can be applied widely to hydraulic engineering measurements, not only in the laboratory but also in the field.

유포자성 유산균을 함유한 홍삼양갱의 개발에 관한 연구

윤광선,백남수,김영만 안성산업대학교 2006 論文集 Vol.38 No.-

유포자성 유산균인 Lactobacillus sporogenes는 혐기 조건으로는 젖산 발효율 97%로 homolactic acid 발효를 하였고 호기 조건으로는 배양결과 생균수 20 × 10^(8)CFU/mL로 포자형성율도 97%를 얻었다. 또한 유포자성 유산균을 이용한 홍삼양갱을 제조하기 위하여 홍삼양갱의 반제품 1kg의 끓인액의 80℃에서 유포자성 유산균을 첨가{20g (spore수 200 × 10^(8) CFU/g)} 제조한 결과 {1.4 × 10^(8) CFU/g (유포자성 유산균 원말 20g/홍삼양갱 1kg)} 제조 후의 생존율이 70%를 유지하면서 끓인 홍삼양갱 제품에 이용 가능성이 높게 나타났다. 이 제품을 건강식품으로 실용후의 결과를 조사하기 위하여 인공위액(pH 3.0)에 대한 내산성을 조사한 결과 4시간 후에 생존율 50%로 나타났다. 그리고 실온에서 1년간 보존시험결과 생존율이 75% 이상으로 저장성이 우수하다고 판단된다. 이상의 결과에서 볼 때 유포자성 유산균을 함유한 홍삼양갱 등의 건강 기능식품의 개발 가능성이 있다고 사료된다. In order to develop red Genseng Thick Jelly containing lactic acid bacteria. Lactobacillus sporogenes spore which has resistance in heat and low pH was used. Jar fermentor culture of Lactobacillus sporogenes under aerobic condition was showed that the number of spore reached about 20×l0^(8)CFU/㎖ and sporulation rate was 97% and lactic acid production yield was 97% under anaerobic condition. The survival rate of Lactobacillus sporogenes spore showed 70% in the product after addition in 80℃ hot jelly solution. In the treatment of artificial gastric juice(pH 3.0) for 4 hours, the survival rate was 50%. It's storage stability was 70% during the 12 months at room temperature. These results suggest that red Genseng Thick Jelly containing lactic acid bacteria play a role as functional food.

WASP5를 이용한 신갈저수지 하수종말 처리장 가동시의 부영양화 및 수질변화 예측

윤병만,노영신 명지대학교 산업기술연구소 2001 産業技術硏究所論文集 Vol.20 No.-

As the amount of sewage is increased around Gi-heung, it is recommended to construct the terminal disposal plant of sewage in Singal reservoir. In this study, therefore, the effect of terminal disposal plant of sewage in Singal reservoir is estimated and predicted by using numerical model WASP5 which is useful for water quality simulation of river, lake and reservoir. The results reveal that the organic matter will be decreased when the plant is operated at the reservoir. However, the operation of disposal plant does not have significant effect on nutrient and therefore, the eutrophication is still expected in spite of the disposal plant construction.

STD61종 열간금형강의 수명향상을 위하여 ion nitriding처리를 실시하였다. 이온질화전의 모재의 열처리시에는 1030˚C에서 quenching한 후 530˚C에서 2시간 tempering했을 때 Hv=600의 높은 경도값을 나타내었다. 580˚C, 600˚C에서 2시간 tempering했을 때는 각각 Hv=500, Hv=400으로 경도값이 오히려 감소했다. 이온질화 처리시에는 처리시간이 길고 N₂와 Ar첨가유량이 많을 수록 깊은 화합물층과 확산층을 얻었다. 그리고 각 처리조건에서 안정된 Hv=1150의 질화물층을 얻을 수 있다. Ion nitriding treatment has been practiced to improve the life of hot die steel of STD61. Before nitriding the parent STD61 tempered at 530˚C, 2hrs after quenching at 1030˚C, It showed the high hardness distribution of Hv=600. The hardness distribution has decreased by Hv=400, Hv=500 when tempered for 2hrs at 580˚C, 600˚C. In the ion nitriding, the more treat-time and the more N₂and Ar flux, the deeper the compounded layer and the diffused layer. The stable hardness, Hv=1150, of nitride layer was obtained at various treatment condition.
