동국대학병원에서는 1992년 2월부터 1995년 12월까지 3년 10개월동안 외상에 의한 횡격막 파열환자 14fl를 수술치험하여 이를 분석하였다. 대상환자는 남자가 10례, 여자가 4례였고, 연령은 17세부터 73세까지로 평균연령은 41.7세였다. 손상의 원인은 둔상 12r11(85.7%), 관통상 2fBl(14.3%)였으며, 둔상에서는 교통사고 lIfTl, 압좌상 1례였고 관통상은 2례 모두 칼에 의한 자상이었다. 들상에 의한 횡격막 파열 12례 중에서는 좌측 손상이 7례(58.3%), 우측 손상이 5례(41.7%)로 우측 파열이 비교적 많은 비율을 차지굻였으며, 관통상에 의한 2례는 모두 우측 파열이었다. 단순흉부촬영, 전산화단층촬영, 초음파검사, 그리고 방사선투시검사 등을 이용하여 횡격막 파열을 진단하였으며, 14례 중 8례는 술전 진단하였고(57.1%), 술전 진단이 안된 경우는 6511(42.9%)였으며 모두 우측 파열이었다. 이들 중 5례는 횡격막 파열을 의심하여 시행한 시험적 개흉술로 진단하였으며, 1례는 동반손상에 대한 개흉술 중에 발견되었다. 우측 파열 7례는 개흉술로 수술하였으며, 좌측 파열의 경우 6례는 개복술로, 1례는 개복술 및 개흉술로 수술하였다. 술후 2례에서 사망하 \ulcorner수술사망율은 14.3%였다.

Eventration of the diaphragm is, by definition, abnormally high or elevated position of diaphragm as a result of paralysis, aplasia or atrophy of varing degrees of muscle fibers, and the cause of which may be congenital or acquired. The unbroken continuity of the diaphragm differentiates it from diaphragmatic hernia. The clinical manifestations of the condition, if present, are usually due to the interference of the ventilatory function of the lung and digesive dysfunction due to gastrointestinal distorsion. Treatment consists of surgical repair of the relaxed diaphragm to it`s normal position. A ease of left sided eventuration of the diaphragm, 31 year old officer, was found by chance after traffic accident with chief complaints of hemoptysis and multiple superficial contusions. Routine chest roentgenogram and barium study of the colon revealed moderately elevated left hemidiaphragm with displacement of the splenic flexure of the colon into the left chest. Past history revealed frequent attack of upper respiratory infection and some abnormal condition on his left chest announced by screen cheek of chest X-ray at the time of entrance for his army service 3 years before. Plication of the relaxed diaphragm through left thoracotomy was done and result was excellent as seen on Fig. 5. Cause of eventration of the left hemidiaphragm was due to paralysis of the left phrenic nerve which was tested during thoracotomy.

선천성 횡격막탈장은 신생아기에 응급 수술을 요하는 질환으로 주로 좌측에 많이 발생한다. 우측 선천성 횡격막 탈장은 드물며 증상이 경미하여 신생아기 이후에 발견되는 경우가 많다. 치료는 전통적으로 개흉술을 통한 횡격막 봉합술이 시행되지만 흉강경을 이용한 수술이 적용되어 좋은 결과들이 보고되고 있다. 우리는 우측 선천성 횡격막 탈장을 가진 5개월된 여아를 흉강경을 이용하여 수술하였기에 보고하는 바이다.

This note contains the following results for a ring A : (1) A is simple Artinian if and only if A is a prime right YJ-injective, right and left V-ring with a maximal right annihilator ; (2) if A is a left quasi-duo ring with Jacobson radical J such that $_{A}$A/J is p-injective, then the ring A/J is strongly regular ; (3) A is von Neumann regular with non-zero socle if and only if A is a left p.p.ring containing a finitely generated p-injective maximal left ideal satisfying the following condition : if e is an idempotent in A, then eA is a minimal right ideal if and only if Ae is a minimal left ideal ; (4) If A is left non-singular, left YJ-injective such that each maximal left ideal of A is either injective or a two-sided ideal of A, then A is either left self-injective regular or strongly regular : (5) A is left continuous regular if and only if A is right p-injective such that for every cyclic left A-module M, $_{A}$M/Z(M) is projective. ((5) remains valid if 《continuous》 is replaced by 《self-injective》 and 《cyclic》 is replaced by 《finitely generated》. Finally, we have the following two equivalent properties for A to be von Neumann regula. : (a) A is left non-singular such that every finitely generated left ideal is the left annihilator of an element of A and every principal right ideal of A is the right annihilator of an element of A ; (b) Change 《left non-singular》 into 《right non-singular》in (a).(a).

A 16-month old female Golden retriever dog was presented with a 2-week history of left-sided exophthalmos, third eyelid prominence, some scale of the trunk, mild anorexia, mild diarrhea and depression. In radiographic findings, a mass with increased opacity in the left retrobulbar area was observed. Cytologic and histopathologic examinations after enucleation and mass excision showed diffuse round cell accumulation and adjacent small area of elongated cell proliferation were shown. They also illustrated the neoplastic cells with large nucleoli, multiple nucleoli that differ in size and scant cytoplasm with several clear vacuoles. Extent of local invasiveness and central necrosis of the retrobulbar mass was identified by magnetic resonance imaging. Based on the physical and laboratory examination, radiographic, cytologic and histopathologic findings this case was diagnosed as extranodal malignant lymphoma of the retrobulbar area.

We performed a percutaneous vertebroplasty at the compressed L2 vertebral body of a 73-year-old female using a left-sided unilateral extrapedicular approach. She complained severe radiating pain and a tingling sensation in her left leg two hours after the vertebroplasty. Spinal computed tomographic scan showed a large retroperitoneal hematoma, and a subsequent spinal angiography revealed a left L2 segmental artery injury. Bleeding was successfully controlled by endovascular embolization. Recently, extrapedicular approaches have been attempted, allowing for the avoidance of facet and pedicle injury with only a unilateral approach. With this approach, however, the needle punctures the vertebral body directly. Therefore, this procedure carries the potential risk of a spinal segmental artery.

The nutcracker syndorme refers to compression of the left renal vein between the aorta and the superior mesentric artery which results in renal vein, left gonadal vein varices, hematuria and left sided flank pain. We report this experience of 11yr-11mon of girl has typical Nutcracker syndrome with persistent proteinuria and without typical hematuria. According to the renal biopsy for persistent proteinuria, biopsy shows pathologic findings similar to minimal change nephrotic syndrome. All symtpoms relieved without any specific treatments but she had no response to steroid treatment for persistent proteinuria. Now she was followed up through OPD base without symptom and consideration of surgical intervention.

Chronic mitral valvular insufficiency (CMVI) is the most common heart disease in dogs. The prevalence of CMVI is age-dependent. CMVI is usually affected to small to medium size breeds. It is more prevalent in males than females. The characteristic lesions of CMVI are caused by an acquired chronic structural degeneration of the mitral valve defined as endocardiosis or myxomatous degeneration. The main clinical signs are cough, respiratory distress, weakness and pleural effusion and ascites by secondary right-sided heart failure. The most prominent clinical finding is a systolic heart murmur. The thoracic radiography and echocardiography are useful methods in diagnosis of CMVI. Thoracic radiographic findings are left atrial enlargement, left main stem bronchial compression and pulmonary edema. Echocardiography is confirmed to increased left atrial and ventricular dimension, mitral regurgitation, mitral valve thickening and abnormal movement. Thoracic radiography and echocardiography are used to obtain a definite diagnosis of CMVI, and then to study the progression of the condition.

Recently, creative innovation has become a major topic in management innovation and due to this, various researches on its need and methodologies are being performed. According to previous studies on ambidexterity, explorative innovation is closer to divergent and right-sided brain, while exploitative innovation is closer to convergent and left-sided brain. Topic was to identify preceding element which affects Ambidextrous Innovation. For this topic, 129 Six Sigma projects from 19 different companies were collected. Ambidextrous index from preceding studies was used. This index represents the degree of ambidextrous activation and can be calculated by multiplying cumulative usage of exploitative tools with that of explorative tools. In the project characteristics, simple linear regression result showed leadership degree, team's vitalization degree and leader capability degree have effect in positive direction.
