김진혁,이상민,정의룡 인제대학교 백병원 2002 仁濟醫學 Vol.23 No.5

A60-year-old female patient with Andersson lesion is presented. Andersson lesion or spondylodiscitis in ankylosing spondylitis is a rare but well-known condition defined as an erosive and sclerotic process involving the intervertebral disc and adjacent vertebral bodies. The causes of this condition are not well understood. The Andersson lesion is often painful, and needs surgical treatment. The patient underwent segmental pedicle screw fixation and posterior fusion without any anterior procedure. The clinical features are presented with leterature review.

유럽 부조리문학의 탈 현대성

이상혁,양병현 尙志大學校 1998 論文集 Vol.19 No.-

It is true that modern absurd literature has been discussing the features of nihilism in terms of Western existentialism. So, absurd writers are supposed to deny the existing structure that determines our modes of thinking by showing the problematic consciousness of contemporary culture. They refuse the optimism inherent in mankind's future, an optimism that originates from rationalism and scientific thought. They reveal irrational concerns in religion, and thereby bring about extreme nihilism in the world. They start with the absurd recognition that it is absurd to understand human beings and the world on a normal basis, and then try to define the parameters of this absurdity. Also, they refuse the Sartrean type of existentialism which believes in human reason and judgment. They pursue modern humanism and liberalism in extreme ways. Some criticize such efforts as the result of overriding subjectivism. Nonetheless, this paper attempts to review positively the characteristics of the 20th century absurd literauture in order to redefine them within the cultural definition of the 21th century. Hence, this paper will demonstrate that postmodernity has evolved from absurd literature which denies humanistic thought, freedom of judgment, and its value, by dealing with Europen absurd writers and their works up to 1980's

ATM망에서 실시간 연결수락제어에 관한 연구

장혁,김영훈,김용수,김희철,나상동 조선대학교 동력자원연구소 1997 動力資源硏究所誌 Vol.19 No.1

본 논문은 이질적 버스트 트래픽을 갖는 ATM(Asynchronous Transfer Mode) 망에서 실시간 연결 수락 제어를 위한 유체 흐름 모델(fluid flow model)에 기반을 둔 실시간 알고리즘을 제안한다. 셀 손실 확률은 QOS(Quality of Service)의 기준이 되므로 제안된 실시간 알고리즘은 일정한 메모리 크기와 연결 요청의 수락 여부 즉, 연결 수락 여부의 결정을 위한 하나의 영역을 필요로 한다. 이러한 트래픽 소스 각 타입에 대한 셀 손실 확률은 트래픽 소스 타입 전체에 하나만 존재하더라도 요구를 충족 시킬 수 없으므로, 본 논문에서 제안된 실시간 알고리즘에 의해 산출되는 각각의 셀 손실확률에 충분한 상한선을 제공하는 전형적 트래픽 매개변수를 사용하여 성능을 분석한다.

고상백,김형식,최홍렬,김지희,송인혁,박준한,박종구,장세진,차봉석 大韓産業醫學會 2000 대한직업환경의학회지 Vol.12 No.1

목적 : 이 연구에서는 한 사업장의 동일한 코호트내에서 직업성 요통의 발생 및 발생원인에 대해 조사하고자 하였다. 방법 : 연구대상은 1995년 12월 현재 한 조선업체에 종사하는 근로자 중에서 1995년 12월 31일 까지 요통이 이미 발생한 근로자와 1995년 당시 검진 미수검자를 제외한 9,784명을 연구대상으로 하였다. 요통 발생군은 1996년부터 1998년까지 3년간 추적 관찰하여 요통으로 4일 이상 통원 또는 입원치료를 받은 근로자로 하였다. 발생률은 요통발생 당시 연도를 기준으로 하여 해당 연도의 4일 이상 신규치료를 받은 중등도 이상의 요통근로자를 분자로 하였고, 해당년도 사업장의 종사하는 근로자 총수(과거 요통자 제외)를 분모로 간주하였다. 요통 발생군은 외상성 요통과 직업관련성 요통으로 대별하였으며, 위험요인과 질병 발생간의 관련성을 보기 위한 Cox모형에서 그 위험도를 파악하고자 할 때에는 직업성 요통만을 환자군으로 선정하였다. 결과 및 결론 . 요통 발생률은 근로자 천명당 1998년 3.1명, 1997년 8.8명, 1996년 7.8명이었다. 요통점유율의 범위는 10.99∼25.66이었다. 연령별 요통 발생률은 30대, 40대에서 높은 발생률을 보였다. 진단명에 따른 발생률은 추간판 탈출증, 염좌, 척추골절, 척추분리증, 척추협착증 순이었다 직업성 요통 발생자들의 직업적 요인을 알아보기 위하여 요통 발생 당시 작업형태를 알아본 결과, 물건을 들다가 66명(35.3%)이 발생하여 가장 큰 빈도를 차지하였고, 물건을 옮기는 과정에서 19명(10.2%)이 발생하여 2위를 차지하였고, 넘어지거나(8.6%), 물건을 당기는 자세(8.0%), 값자기 일어서다(7.5%) 순으로 요통이 발생하였다. 직업성 요통에 영향을 주는 일반적 특성 및 직업적 특성에 판한 상대위험도 및 95% 신뢰구간를 구한 결과, 요통발생에 영향을 주는 유의한 변수로는 체질량 지수(비만도), 교대여부, 중량물 취급여부였다. Objectives : This study was conducted to estimate the incidence rate, and to identify the risk factors for the occupational low back pain among shipyard workers. Methods : The study subjects consisted of 9,784 workers who were employed in a ship-building industry (excluded workers who had a history of low pack pain before 1995 or did not take periodic health examination in 1995) . The cases were 220 people who experienced back pain from January 1, 1996 to December 31, 1998. To assess risk factors for occupational low back pain, Cox propotional hazard model was used. Results : During the recent three years from 1996 to 1998, the incidence rate per 1,000 persons was 7.8 in 1996, 8.8 in 1997, and 3.1 in 1998. The main causes of work-related low back pawn were sprain, strain and disc herniation. Lifting was the most common cause of back pain (35.3%) , and carrying (10.2%) and pulling (8.0%) were followed. In Cox proportional harzard model, independent risk factors for back pain were body mass index(R.R. ; 1.54, 95% C.1. : 1.06-2.25), shift work(R.R. ; 1.65, 95% C.1. : 1.19-2.28), and lifting heavy material(R. R., 3.95, 95% C.1. : 2.29-6.82). Conclusions . This study suggests that the risk factors of back pawn In shipyard work-ers were body mass index, shift work and lifting.

Objective: To evaluate the efficacy of lumbosacral fusion with bilateral bicortical S1 pedicle screw fixation without anterior support on the basis of the fusion levels in degenerative lumbosacral disease. Materials and Methods: Seventy three patients were treated with posterior decompression and posterolateral fusion with bilateral bicortical S1 pedicle screw fixation. Their results were analyzed retrospectively with minimum 2-year follow-up. Postoperative anteroposterior and lateral radiographs were analyzed for S1 screw loosening, fixation failure and lumbosacral fusion. Medical records were analyzed for postoperative low back pain and complications. Results: S1 screw loosening was 1(6.3%) in 2 level fixations, 3(14.3%) in 3 levels, 7(5O.0%) in 4 levels and 13(86.7%) in more than 5 levels. Fixation failure was 1(4.8%) in 3 levels fixation, 1(7.1%) in 4 levels, 5(33.3%) in more than 5 levels. Non-union was suspected in 30 patients(41.1%), 1(14.3%) in mono-level fixation, 2(12.5%) in 2 levels, 8(38%) in 3 levels, 9(64%) in 4 levels and 10(67%) in more than 5 levels. Postoperative sustained low back pain was 1 in 3 levels fixation, 2 in 4 levels and 7 in more than 5 levels. Postoperative complications were detected in more than 3 level fixations ; hematoma in 2, wound infection in 6, progressive kyphosis in 2. Conclusion: Lumbosacral fixation with bilateral bicortical S1 pedicle screw could not provide satisfactory outcome in long level fusion especially in more than 4 levels fusion of degenerative lumbar disease.

The inflammatory myofibroblastic tumor (inflammatory pseudotumor) is a rarely occurring soft tissue lesion of unknown etiology. It can be of any location, but commonly it is found in lungs. It has been considered as a nonneoplastic reactive inflammatory lesion, but nowadays, confusion and dispute about its character is increasing due to its high recurrence rate and metastasis. We present a patient who had been diagnosed with an inflammatory pseudotumor in the right maxilla area, 1 year before visiting our hospital. After that, her pain and swelling did not resolved and she visit our hospital. On radiographic examination, aggressively infiltrative growth of the lesion with destruction of adjacent bony structure was noted. We found unusual aggressiveness of the inflammatory myofibroblastic tumor of the head and neck region. Because the typical behavior of the inflammatory myofibroblastic tumor is not defined yet, we recommend the surgical excision of the lesion and close follow-up.

김진혁,이상민,정의룡 인제대학교 백병원 2002 仁濟醫學 Vol.23 No.5

Objectives: To evaluate the surgical outcomes of congenital scoliosis with hemivertebra corrected by posterior vertebral column resection after a minimum follow up of 2years. Materials & Methods: Thirty five congenital scoliosis cases(20 males and 15 females) subjected to posterior vertebral column resection and without any previous operative intervention were analyzed. They were analyzed for deformity correction and complications. The mean age at operation was 14.6 year-old(range 2.6~35) and mean follow-up was 3.1 years(range 2.0~4.5). The preoperative index curve was 44.5±15.8° in coronal plane, and 22.7±35.9° in sagittal plane. Results: The total number of resected vertebrae were 36 : 17 in thoracic and 19 in lumbar. The deformity correction was 57.0% with 19.0±10.6° in the coronal plane and 69.0% with 7.0±14.9° in the sagittal plane. Mean operation time was 222.7±54.9 minutes with a total perioerative transfusion of 1992.0 ㎖. Complications were encountered in 3 patients(8.6%) : 1 hematoma and cauda equina syndrome, 1 fixation failures and 1 transient posterior cord syndrome. Conclusion: Posterior vertebral column resection in congenital scoliosis with hemivertebra is an effective method compared to anterior-posterior two stage hemivertebra resection. It could offer satisfactory correction of deformity and restoration of spinal balance.
