Calculous anuria is one of the complications of upper urinary tract calculi and may be caused by mechanical obstruction at some point of the tract, renal insufficiency, and a combination of obstructive and renal factors. The clinical features may vary from a complete absence of symptom to the time when the patient observes he could not pass urine. An immediate roentgenogram and catheterization of the ureters in an attempt to restore the excretion of urine are always recommended and in from 50 to 55 per cent of the patients the calculus is expelled. Even if anuria recurs after withdrawal of the catheter, the patient is in better condition for surgical intervention as a result of the removal of accumulated nitrogenous waste products. Uric acid calculi comprise from 3.5 to 4 percent of urinary calculi. A low purine diet, allopurinol and alkalinization of urine are proved very effective in management of it. Recently we have experienced a case of calculous anuria due to bilateral ureteral stones in 41 years old man and present it with the review of the literatures.

$CO_2$ 첨가가 $CH_4$-공기 대향류 확산화염의 구조 및 NOx 생성에 미치는 영향
이승로,한지웅,이창언,Lee, S.R.,Han, J.W.,Lee, C.E. 한국연소학회 1999 한국연소학회지 Vol.4 No.2
This numerical study was to investigate the effect of $CO_2$ addition on the structures and NOx formation characteristics in $CH_4$ counterflow diffusion flame. The importance of radiation effect was identified and $CO_2$ addition effect was investigated in terms of thermal and chemical reaction effect. Also the causes of NOx reduction were clarified by separation method of each formation mechanisms. The results were as follows : The radiation effect was intensified by $CO_2$ addition. Thermal effect mainly contributed to the changes in flame structure and the amount of NO formation but the chemical reaction effect also cannot be neglected. The reduction of thermal NO was dominant with respect to reduction rate, but that of prompt NO was dominant with respect to total amount.

Use of US to evaluate the brain lesions for the first time was in 1956 by Leksell, who tried to detect the midline of brain with A-mode. After that B-mode was used in 1970's and reported US findings of variable brain lesions in early 1980's in foreign countries, but not widely used in ours. Authors analysed US findings of 54 cases (45 who performed through anterior fontanelle and tem-poroparietal thin one and 9 through the surgical bone defect) and compared with CT image to reconfirm the efficacy of US. We could conclude that using US, as initial screening and follow up method in neonate, infant and early childhood under 15 montha and as a follows up method in post operative patient, was not inferior to CT and was more effective in cases of abscess and cystic lesions.

Morphologic changes of spinal canal and dural sac during spinal movement (flexion-extension) were analysed and reported with the base of cross sectional anatomy, as early as 1942. After that, this movement was emphasized and used in myelography in many countries under the name of functional myelography, for accurate diagnosis of spinal stenosis of spinal stenosis as herniated disc, but not used commonly in Korea. Authors analysed functional myelographic findings of 78 cases, 37 of normal and 41 of surgically confirmed herniated herniated disc, to intend to confirm the necessity of spinal movement dudring myelography. the result were as follows; 1. In normal group, anterior border of dural sac is straight with flexion, but indented in extension at the level of intervertebral space and this indentation is less prominent at L5-S1. 2. In normal group with extension, posterior indentation of dural sac is more prominent at the level of intervertebral space than body, A-P diameter of dural sac is narrowed all the level of intervertebral space except L5-S1. and dural sac moved anteriorly (near to the posterior portion of spinal body or intervertebral space)at the level of L5-S1 and all spinal body. 3. In disc patient, anterior indentation of dural sac is persist in both views (flexion & extension) and much more exaggerated with extension, but less prominent at L5-S1. 4. In herniated dics with extension, anterior movement of anterior dural border at the level of L5-S1 is much ecreased than normal.

니켈-크롬 합금과 Porcelain laminate의 결합력에 관한 연구
이승로,진태호,동진근,Lee Seung-Lo,Jin Tai-Ho,Dong Jin-Keun 대한치과보철학회 1992 대한치과보철학회지 Vol.30 No.1
The purpose of this study was to evaluate the bonding strength between porcelain laminate and Ni-Cr alloy in the various surface treatments of the bonding faces. For this study the metal surface of specimens were treated : 1) etching only, 2) sandblasting only, and 3) sandblasting and etching. The porcelain laminate were made and bonded to the metal specimens with light curing composite resin cement. Instron testing machine was used to measure their bonding strength : and the result was obtained as follows : 1. The bonding strength of the double treatment of the sandblasting and etching group was higher than that of the single treatment of sandblasting or the etching group. 2. The bonding strength of the sand blasting group was higher than that of the etching group. 3. The debonding were mainly occurred between the Ni-Cr alloy and the composite resin cement.

Voice Onset Time Variations of Korean Stop Consonants in Aphasic Speakers
이승로,고명환,김현기 대한재활의학회 2011 Annals of Rehabilitation Medicine Vol.35 No.5
Objective To compare the voice onset time (VOT) differences of Korean stops in the initial and intervocalic positions between the aphasic patients with peculiarities of aspiration and a control group. Method We examined 15 aphasic patients (nine males, six females) who had suffered a stroke (average age 49.7years) and 15 healthy controls (average age 47.4 years). An aphasia examination was made by an aphasia battery of three standard tests and VOT was analyzed instrumentally. Stop consonants in the initial and intervocalic position were measured to categorize them according to aphasia types, place of articulation, and manner of articulation. Results VOT of the aphasic patients with peculiarities of aspiration had a greater difference than that of the controls, indicating that the temporal non-coordination between the laryngeal adjustment and oral articulators of aphasic patients happens due to the VOT of stops in the initial and intervocalic positions (p<0.05). Conclusion VOT of stop consonants in the initial position produced by aphasic patients tends to be proportional to their breathing. It can cause glottal width and make aphasic patients’ VOT duration longer. Lastly, the method to measure the VOT of aphasic patients is more significant for the types of phonation than for the places of articulation, and makes it possible to induce abnormal VOT.
