Excretory urography is a type of contrast study used to verify and localize upper urinary tract disease. It is an inexpensive and easy way to visualize of anatomic and functional status of the kidney and has been used as a primary imaging modality for the evaluation of urinary tract abnormalities. We describe urological signs of 7 dogs who examined with excretory urography and ultrasonography. Six cases were referred to veterinary medical teaching hospital. Chungnam national university (VMTH, CNU) to evaluate renal function after the treatment for renal failure and one case was referred showing hematuria. In case 1, 2 and 4, blood test and urinalysis was normal and the results of excretory urography presented that renal function were normal range. In case 3, the results of urinalysis, ultrasonography, and excretory urography except blood test presented abnormal kidney and hydronephrosis was diagnosed. In case 5 and 6, blood test, urinalysis, ultrasonography and excretory urography indicated renal failure. In case 7, blood test, urinalysis and ultrasonography presented partially abnormal signs, however, the results of excretory urography was normal range.

최원익,김용대,심준환,이종현 경북대학교 센서기술연구소 1998 센서技術學術大會論文集 Vol.9 No.1

Probe card is the most important part of testing IC chips. This work was related to silicon vertical probe card which enabled to simultaneously test multiple semiconductor chips. We presented Bump-type vertical probe card. It was fabricated by dry etching using RIE technique, isotropic etching, and bulk-micromachining on SDB wafer. The process used in this work was very simple and reproducible, which had good controllability in the probe card dimension and spacing. It is expected that the fabricated probe card can reduce testing time, can promote productivity and enables bum-in test.

崔龍俊,朴暎淳,金世吉 圓光大學校 韓醫學硏究所 1994 원광한의학 Vol.4 No.1

The present experiment was designed to investigate the effects of Insambokmaektang(人蔘復脈湯) on the blood pressure, heart rate, respiratory frequency, respiratory rate and the activity of gastromuscular system. In order to control the precise physiological conditions, the experimental rabbits were supplied with calorie limited food. The therapeutic effects of Insambokmaektang on the low heart rate and hiccups were discussed in this study. The results obtained here were summarized as follows: 1. Insambokmaektang increased the blood pressure 32.6% and 32.3% after injecting it at 5 and 10 minute respectively. 2. The drug increased the heart rate 41% and 41.6% after injecting it at 5 and 10 minute respectively. 3. The drug increased the respiratory frequency 50.9% and 76.5% after injecting it at 1 and 2 minute respectively. 4. The drug decreased the respiratory depth 7.2% and 3.6% after injecting it at 1 and 2 minute respectively. 5. The autonomic nerve blocking agents(Phentolamine, Propranolol, Atropine) did not take the effect of the drug function on the blood pressure and heart rate. 6. The autonomic nerve blocking agents(Phentolamine, Propranolol, Atropine) did not take effect of the drug function on the respiratory frequency and respiratory depth, however, atropine increased the respiratory depth and decreased the respiratory frequency. 7. The drug inhibited the activity of ventricular myocardiac Mg^2+ -Ca^2+ -ATPase and thus stimulated the cardiomuscular contraction. And the inhibitory mechanism was reversible noncompetitive. 8. The drug inhibited the total ATPasd activity of stomach smooth muscle. According to the above results, Insambokmaektang is assumed to have a curative effects for the low heart rate and hiccups.

The main purpose of this research is the investigation of water distributer. The water distributer of this research is installed in evaporative cooling tower system. The performance of this cooling tower system depend on the evaporative surface, and there are many kinds of methods for increasing the evaporative surface. In this research, we introduced the two kinds of spraying system, one is the hole type with hole diameter 1, 2 and 3mm, and the other is the spray nozzle types with nozzle tip diameter of 1 and 2mm. As the experimental results, the case of diameter 2mm showed the best performance.

JDBC를 이용한 Web-GIS 구현

전홍구,최관순,공용해 순천향대학교 부설 산업기술연구소 1999 순천향 산업기술연구소논문집 Vol.5 No.2

GIS is evolving from a technology that addresses specific applications to a broad-based information system. Its value goes beyond increased efficiency, cost savings. Therefor GIS will be fundamental to the future on the internet. But our organizations and societies exclusively handle geographic informations in Korea. and they use independently foregin commercial GIS softwares. It makses difficult to accmulate local techniques in GIS. In order to solve this problem we implement WEB-GIS using JDBC without depening specific software.

The purpose of this research is to obtain the characteristics of strain and stress in the vacuum pressure vessel. The vacuum pressure vessel is used to many of industrial devices and cooling tower system. The vessel is under the vacuum pressure in this research, and we analyzed the stress on the vessel surface. As the experimental set up, we introduced the Static Strain Measurement(UCAM 70A, Kyowa) system. The environmental condition of vessel is reserved under vacuum pressure 50mmHg, and the vacuum pressure was made by a ejector pump system.

Serum leptin, glucose, lipid profiles (free fatty acid, triglyceride, total cholesterol) were determined in two groups of subjects undergoing long and short strenous cycle race, 8 men who fasted overnight and then pedaled 20km cycle race and 8 men, 150km cycle race, respectively, Blood samples were collected before race, immediately after cessation of race and 2hr, 6hr after the end of race period. Cyclist pedaling 20km cycle race and cyclist pedaling 150km cycle race showed no statistical differences in leptin level. After 6hr of rest, leptin concentrations were gradually decreased but showed no statistical different in both groups. Epinephrine (p〈.01) and norepinephrine (p〈.001) concentration in comparison to pre-race levels were increased significantly. But insulin concentration in comparison to pre-race levels were decreased significantly (p〈.001). Glucose (p〈.01), free fatty acid (p〈.001), cholesterol (p〈.001) and triglyceride (p〈.01) were increased immediately after cessation of race in both groups.

최상태,전용우 경주대학교 건설환경연구소 2000 建設環境論叢 Vol.- No.3

In this paper, the removal rate of NO in a reactor is measured first using nonthermal plasma generated from a wire-cylinder type reactor, then the discharge image and horizontal signal strength and vertical signal strength of NO particles is observed using ICCD(Intensified Charged Coupled Device) camera. It was found that NO removal rate was increased with NO concetration decreasing, and that horizontal signal strength and vertical signal strength were also increased with NO concentration decreasing. Especially, this research is aimed at clarifying the NO characteristics by observing the images of AC discharge when the nonthermal plasma generated by as discharge( electrical method ) was used.

한양학원 폐수의 미생물학적 처리에 관한 연구

최용,최영길,이희준,안연준 漢陽大學校 環境科學硏究所 1994 環境科學論文集 Vol.15 No.-

한강수계인 안양천에서 유출되는 산업페수에서 카드뮴과 납에 내성을 지니며 이들 중금속을 축적하는 균주 HYM 2., HYM 40을 분리하여 동정한 효모인 Torulopsis inconspicua로 밝혀졌다. 납의 경우 180mg/g dried cell, 카드뮴의 경우 147.5mg/g dried cell까지 축적한는 것을 확인하였다. 전자현미경으로 관찰한 결과 이들 중금속은 주로 세포막에 축적되는 것으로 나타났다. 이 균주를 한양학원 폐수를 재료로 하여 pilot system에 적용한 결과 원폐수만을 적용했을 때보다는 활성슬러지를 첨가했을 때 (MLSS를 2000∼3000mg/ㅣ로 보정), 특히 분리된 균주를 적용시켰을 때 중금속의 제거 효율이 훨씬 더 증가하였다. 이는 환경오염원을 제어하는 균주를 직접 실공정에 적용할 수 있는 가의 가능성을 타진할 수 있었다. Two strains of yeasts, HYM 20 and HYM 40, which have resistance against heavy metals such as cadmium and lead and have ability to accumulate the heavy metal were isolated in the industrial sewage drained from Anyang stream. These strains of yeasts were identified as Torulopsis inconspicua. This yeast accumulated lead upto 180mg/g dried cell and cadmium 147.5mg/g dried cell. In the electron microscopic analysis, it was observed that the heavy metals were accumulated within the cell membrane. In the application of wastewater from Hanyang University to the A₂/0 system, increased accumulation was observed when the original sewage was added with active slvge by comparison with the sewage alone. particulaly, when added with sluge and isolated strains, higher increasemant of accumulation was boserved than in the former cases. These results showed the possibilities for the practical elimination of heavy metal pollutants.
