질소시비가 한국잔디의 생육과 Thatch 축적에 미치는 영향
윤용범,이주삼 한국잔디학회 1990 한국잔디학회지 Vol.4 No.2
This experiment was carried out in drder to study the changes of morphological characters and thatch weight on N-level and survey times N-levels were 0, 21, 28, 35, 42 and 49 g/m$^2$), respectively. The results are as follows. 1. Thatch weight was significantly different among survey times, and the interaction of survey time N-level. 2. The growth of Zoysia grass and thatch accumulation were incresed by higher N~level The highest value was obtained in all survey times. 3. Most survey characters and thatch accumulation was decreased by growth progressed. 4. Thatch increase rate(TIR) was the lowest at 28g Nm$^2$and T2-T3 period. 5. TIR was the positive significant correlated(P<0.05) with N-level, root weight, clipping weight and thatch weight.
Dubin - Johnson 증후군 (증후군) 10예에 대한 임상적 (임상적) 고찰
윤용범,이원표,김정용 ( Yong Bum Yoon,Won Pyo Lee,Chung Young Kim ) 대한소화기학회 1980 대한소화기학회지 Vol.12 No.1
The Dubin-Johnson Syndrome is characterized by chronic, mild, predominantly conjugated hyperbilirubinemia with a blcak liver and pigmentation of parenchymal liver cell. The disor- der result from an inherited abnormality in the excretion of various non-bile salt organic anion from the liver cell into the bile. It is benign non-progressive and not associated with any form of chronic hepatic or biliary tract disease. The diagnosis of the Dubin-Johnson synd- rome is established by secondary rise in BSP retension test and needle biopsy of the liver. The important consideration in managing patient with this disorder are the reassurrance that the abnormality is benign and leads to no disability or reduction in life expectancy and the avoidance of unnecessary biliary tract surgery. Clinical observation was made on 10 cases of Dubin-Johnson Syndrome admitted to department of internal medicine, Seoul Xatio- nal University Hospital from 1969 to 1979. The following results are obtained 1. The male to female ratio was 6: 4 and the majority of the caes are in 'rd decale 2. There avere 3 cases of jaundice on family history and 2 cases ,vere 'orother nd sister relationship The chief complaints on admission were in order of jaund!ce, Satigue, rigiit upper abd- ominal oain and darl- urine. Hepatomogaly was observed in 5 cases, but there was no case of splenomegaly The average serum total biliubin level was Z. 98+ l. 29mg/100ml and the average serum conjugated bilirubin level vas l. 7p0. 94 mg/lpQml. Other liver function tests revealed normal v lues. 6. HBsAg and aFP test were performed in 5 cases and the results wcre negative in all cases Oral cholecystography was performed in 6 cases and the gallbladder was visualized in 8 cases, suggesting that the important non-visualization of gall-bladder on oral cholecy- stography for the diagnosis of the disorders ought to be reconsidered.
