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.

Armorphous materials have various structures that is determined by different manufacturing conditions. That is, the photoelectric characteristics of films manufactured by different conditions are totally different. The growth mechanism of a-Si should be understood in order to controll the characteristics and structures of these kinds of materials. In this study, we try to elucidate the particle behaviours in a processing plasma using a low pressure glow discharge. And because of difficulties understanding discharge mechanism, we have done the processing so far depending on the experimental methods that compare the thin film produced by varing discharge parameter with the results of micromachinary. But, this has a limitation in the development because it regards the plasma as a blackbox. Therefore, because it needs to observe the discharge parameters and plasma background gas systematically, we try make sure that the particle behaviours be made clean by using laser fluorescence method which is predominant in a phenomina measurement and special resolution.

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.

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.

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.

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 HTTP Protocol composed of WWW's client/server model is unconnected and not keep state, so, there is one connection for one request. In this condition, it has no guarantee to memory which is needed in sequential processing, and HTTP Protocol has no choices to transfer the information from client to server's CGI or the information exchange. This paper uses the word 'key' instead of this 'state information'. We studied the key which creates automatically the HTML document for data search hierarchically in WWW environment and to confirm applied this to multimedia order and sale system of agricultural and marine products.

This study was attempted to investigate the pharmacokinetic interaction between sodium valproate (4. 8. 16 ㎎/㎏. i.v.) and phenytoin (4 ㎎/㎏. i.v) in rabbits. The plasma concentration and area under the curve (AUC) of phenytoin were increased significantly (p<0.05. p<0.01) when coadministered with sodium valproate (4. 8. 16 ㎎/㎏) in rabbits. The volume of distribution and total body clearance of phenytoin were decreased significantly (p<0.05. p<0.01) when coadministered with sodium valproate (8. 16 ㎎/㎏) in rabbit. From the results of this experiment. it is desirable that dosage regimen of phenytoin should be adjusted and therapeutic drug monitoring should be performed for reduction of side or toxic effect when phenytoin will be coadministered with sodium valproate in clinical use.

대기환경개선을 위한 비열플라즈마중의 NO 입자의 거동 연구

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.
