Objectives: The aim of this study is to evaluate the short-term results and complications of treating the intertrochanteric fracture with bipolar hemiarthroplasty (BHA) in elderly population. Methods: We retrospectively reviewed 31 unstable intertrochanteric fracture patients who were treated with BHA between January 2007 and August 2009 in older populations more than 65 years old. The 6 males and 25 females had a mean age of 79.8 years (range: 66-88) and a mean follow-up of 36.3 months (range: 24-55). We analyzed the radiological outcomes, functional recovery grade, using Jensen’s social function score and Harris hip score (HHS), and complications. Results: The average operation time and blood loss was 148.9 min (range, 110-215 min) and 455.2 mL (range, 200-1200 mL). Mean preoperative and postoperative hemoglobin (Hb) was 10.9 g/dL (range, 8.6-13.4 g/dL) and 10.5 g/dL (range, 5.1-14.1 g/dL) respectively. Average 1.3 pints of blood transfusion was performed. Ambulation with (or without) crutch was possible at mean 6.8 days postoperatively. The stability and alignment indices were adequate in all cases at final follow-up. On clinical results, the average HHS score, was changed from 79.7 points (range, 44-100) preoperatively to 73.0 points (range, 46-92) postoperatively, and the preoperative and postoperative Jensen’s score was 1.8 (range, 1-3) and 2.1 (range, 1-4) respectively. Conclusions: The BHA is an acceptable alternative for unstable intertrochanteric fractures in older population.

북양명태를 원료로서 마른명태를 가공하는 실험을 하여 다음과 같은 결과를 얻었다. 원료를 해동하여 내장을 제거하고, 그대로 29시간 열풍건조하여 마른명태를 가공할 수 있었으며, 제품의 수율은 22% 수분은 18%였다. 또한 원료어를 등갈이한 다음 머리, 내장, 흑막을 제거하고, 염장한 다음 22시간 열풍건조하여 건조시간도 단축할 수 있고, 색택도 좋은 제품을 만들 수 있고, 수율은 약 12%였다. 또한 원료어를 fillet로 처리하여 염장한 다음 열풍건조하므로서 건조시간을 더욱 단축할 수 있었고, 포장 및 조리하기에 편리한 제품을 가공할 수 있었다. 제품의 수율은 어체의 크기에 따라 차이가 있어 10∼22%였다. 그리고 채육기로 육을 채취한 다음 과산화수소를 써서 거품을 일어켜 새로운 형태의 다공성인 박층건제품을 가공할 수 있었고, 이 다공성 박층건제품은 흡수성이 좋아 instatant 식품으로 이용 가능하다는 결론을 얻었다. In this paper, some dehydration methods for frozen Alaska Pollack Theragra chalcogramma were studied. The cabinet type drier was used for the study. Samples were dehydrated for appropriate time at the air temperature of 38 to 40℃ under the air stream of 3m/sec. The frozen samples were defrosted, eviscerated, and hot-air dehydrated for 29 hours. The yield of dehydrated product was about 22% and moisture content was 18%. The brine salted samples which were headed, split and skinned were also hot-air dehydrated under the same conditions. This dehydration process could reduce dehydration time. The yield of dehydrated product was about 12% and moisture content was about 20%. For another method, frozen samples were first defrosted, washed thoroughly to remove dirt, slime and scales, and then beheaded, skinned and filleted. The fillet was dehydrated after brine salting. The yield was 10 to 22% and moisture content was 12%. The tissue of these hot-air dehydrated products such as round, split and fillet were very firm and difficult to reconstitute. In order to obtain dehydrated product of agreeable texture, another dehydration process was examined. Chopped meat was dipped in alkaline solution of 0.4% hydrogen peroxide for 30 minutes and then agitated for 10 minutes. By these treatment the foamy and emulsified minced meat was spread on a nylon net seated on metal tray, drained, and dehydrated. A better result was obtained by this process comparing with other's. This could be explained for the reason that the process resulted in the meat flake porous by which the meat could be rapidly reconstituted. The texture of the porous meat flake was good for a convenience food.

조재완,김석일,이군석,김춘배 韓國工作機械學會 2000 한국생산제조학회지 Vol.9 No.4

In this study, a static and dynamic characteristics analysis system for machine tool spindle systems with 3 lobe sliding bearings is developed based on Timoshenko theory, finite element method and windows programming techniques. And the characteristic values of 3 lobe sliding bearings such as eccentricity ratio, attitude angle, friction coefficient, stiffness coefficients, damping coefficients and so on, are determined by using the thermal equilibrium condition of spindle sys-tems. Since the developed system has various analysis modules related to static deformation analysis, modal analysis, fre-quency response analysis and so on, it can be utilized to perform systematically the design and evaluation processes of spindle systems with 3 lobe sliding bearings under windows GUI environment.

北韓 文學論의 硬直性

尹在根 한양대학교 한국학연구소 1991 韓國學論集 Vol.19 No.-

The modern literature in the North Korea has no problem of what the authentic truth of art is. The reason is that it is eaqual to a kind of political activities forward to promoting the only ideology directed by the authority of the North Korea. Therefore to understand what the North Korea literature aims as is to know how the struggle of power-hegemony has been developed in the political field of the North Korea. But the struggle stopped after Kim Il Sung had siezed the crown crownchair of the only dictator. Since then the North Korea literature has been totally subjected to idolize the image of Kim Il Sung dictatorship. The North Korea literature is powerfully interested in how to write rather than what to write, because writers in the North Korea have to receive the one-way directions from the only politic party of Kim Il Sung. The result is that the modern literature in the North Korea has been far from improving and enlarging aesthetic experiences by both freedom and individuality, but it has the only aim to lead people's experiences into the political totality.

ARENA 시뮬레이션을 이용한 차체공장 수행도 분석

정재호,김현근,김향희,전태보 강원대학교 산업기술연구소 2000 産業技術硏究 Vol.20 No.A

Simulation analysis for an auto body manufacturing system has been performed in this study. The major goal is to figure out the condition yielding the production rate, 70 per hour. It is, however, very difficult to maintain this rate due to inherent system factors such as machine failure rates, machine repair rates, number of carriers between manufacturing lines(shops), carrier speed etc. We first carefully examined the system and developed a simulation model using ARENA. We then applied statistical experimental design concepts for performance analysis. Our results indicate that the buffer size of 30 and quick repair of failed robots are required for the desired production rate. Other factors, on the other hand, are seen to have minor effects on the throughput. The approach taken in this study and the results obtained may provide a practical guideline for performance analysis and thus be applied without trepidation for similar cases.

뇌출혈이 합병된 감염성 심내막염 1례

박동건,이재욱,권삼,이동철,강승완 동국대학교 경주대학 1997 東國論集 Vol.16 No.2

감염성심내막염에 의한 신경계 합병증은 색전성 뇌경색, 색전성 뇌출혈, 두개내 패혈성 동맥류, 뇌농양, 뇌막염등 다양한데 항생제 요법의 발달과 판막치환술에도 불구하고 그 빈도는 감소되지 않고 있다. 이 중 두개내 패혈성 동맥류의 파열에 의한 뇌출혈은 사망률이 80%로 치명적일 수 있어 조기 발견 및 적절한 치료가 필요하다. 저자들은 두통, 열감, 근육통 등의 증상으로 내원하여 감염성 심내막염으로 진단받고, 항생제 치료로 임상증세의 호전중에 심한 두통과 전신적 발작이 있은 후 갑자기 발생한 두개내 뇌출혈을 심장초음파 및 뇌 컴퓨터 단층촬영을 통하여 진단, 경험하였기에 문헌고찰과 함께 보고하는 바이다. The complications of infective endocarditis may involve any organ system ie, cardia, neurologic, vascular, dermatologic, and kidney. Extracardiac complications are usually caused by either embolization of vegetations or deposition of immune complexes. Neurologic complications remain a significant problem in bacterial endocarditis and have been reported to occur in up to 20% to 40% of cases of infective endocarditis. The various types of central nervous system disease seen in patients with infective endocarditis are cerebral embolism (with infarction or with intracerebral hemorrhage), intracranial mycotic aneurysm, seizures, brain abscess, meningitis, mental change, psychiatric disorder. Mycotic aneurysms are uncommon but not rare and are an important cause of local or systemic sepsis and acute hemorrhage following aneurysmal rupture. Cerebral mycotic aneurysms have been noted in 2∼10% of cases of bacterial endocarditis and account for 2.5∼6.2% of all intracerebral aneurysms. We have experienced a case of neurologic complication due to infective endocarditis in a 23 year-old female patient, who admitted to our hospital because of fever, chill, headache, myalgia. This case was diagnosed by echocardiography, brain computed tomography. The patient died of sudden intracerebral hemorrhage in the 53th hospital day despite intensive medical treatment. We report one case of intracerebral hemorrhage complicated with infective endocarditis.

목적 : 선천성 고혈압 흰쥐(SHR)와 정상 혈압 흰쥐(WKY)의 혈관 평활근 세포를 배양하여, 그 성장 특성을 조사하였다. 대상 및 방법 : SHR 및 WKY를 pentobarbital(50㎎/㎏)로 마취하여 적출한 흉부대동맥으로부터 혈관평활근세포를 얻었으며 이 세포를 이차배양하여 일정한 시간간격으로 trypsin을 처리하여 세포를 떼어낸후 혈구계(hemocytometer)로 세포수를 헤아렸다. 결과 : SHR과 WKY에서 얻은 혈관평활근세포에서 형태학적 차이는 없었고, SHR이 WKY보다 밀생상태에 더 빨리 도달하며 밀생상태에 도달했을때 SHR이 WKY보다 세포밀도가 더 높게 나타났다. 결론: SHR이 WKY보다 증식속도와 증식밀도가 더 높게 나타나는 것으로 보아 SHR에 성장 억제 조절 기전의 장애가 있음을 시사한다. To study the generation and processes of hypertension, characteristics of vascular smooth muscle cell were observed in cultured aortic smooth mescle cell from spontaneously hypertensive rats (SHR) and normotensive Wistar-Kyoto rats (WKY). The degree of cell proliferation increased with escalating concentrations of fetal bovine serum(FBS) in cells of both SHR and WKY control rats. These results have shown that 10% FBS, which was the usual concentration in culture medium, was better concentration of medium in cell proliferation than 5% FBS, 10% calf serum, 10% horse serum, or 1% bovine serum albumin. There were no detectable differences in the morphology of cells obtained from SHR and WKY. Comparative studies have shown that cultured vascular smooth muscle cells from SHR proliferated to a higher cell number, grew to a greater density, and have greater specific growth rate than those of the WKY. These results provide possibility of a disturbances on inhibitory conrol to vascular smooth muscle cell growth in SHR.
