Purpose : To identify clinical and laboratory features of atypical Kawasaki disease(KD), and to develop criteria for early diagnosis of atypical KD patients. Methods : All patients with KD treated at our hospital from January 1998 to June 2000 were reviewed retrospectively. Results : Among a total of 167 patients, 28(16.8%) were atypical KD of which seven(25%) were infants. Among the five cardinal symptoms, oral mucosal change(96.4%) occurred most frequently, followed by conjuntivitis(57.1%) and rash(46.4%). Most notable laboratory findings were anemia, and increased erythrocyte sedementation rate(ESR) or C-reactive protein(CRP). Coronary artery abnormalities developed in seven(25.8%) atypical KD patients, compared with 14.4% in typical KD patients. We considered oral mucosal change as major criterion, and conjunctivitis, rash, hematocrit <35% and ESR >30 mm/hr or CRP >3.1 mg/dL as minor criteria. Proposed modification in diagnostic criteria for atypical KD include fever of ${\geq}5$ days＋major criterion＋${\geq}2$ minor criteria, or fever of ${\geq}5$ days＋4 minor criteria. Conclusion : The modified diagnostic criteria has yielded a sensitivity 89.3%. Our diagnostic criteria may be used for early diagnosis of atypical KD.

지금까지 우리는 한국어와 독일어를 비교하면서 동사의 정형과 부정형을 관찰해 왔다. 이 부정성(역으로 말하면 비구속성)은 한국어 동사에는 전반적으로 통용되는 데 반해 독일어에는 부정형/동사원형과 분사가 그러할 뿐이다. 동사의 특성 연구는 어느 자연어/개별언어의 상이한 기능을 위해서 뿐만이 아니라 외국어 학습/습득을 위해서도 큰 의미를 갖는다. 이러한 중요성에도 불구하고 독특한 한국어 동사의 부정성, 그 연구는 거의 찾아볼 수가 없다. 한국어와 독일어 동사의 부정성 비교에서 드러난 문제점은 대체로 다음과 같이 요약될 수 있을 것이다. $\ast$ 한국어 동사의 특징인 부정성은 우리의 운명으로 간주해야 할 것이다. 왜냐하면 우리가 어떤 면에서는 유익함을, 그리고 어떤 다른 면에서는 문제점을 감수해야 하기 때문이다. 특히 전형적인 전치성 언어인 유럽언어를 습득할 때 언어간섭현상을 통해 그러하다. $\ast$ 독일어의 부정사/분사 및 한국어 동사가 인칭변화를 하지 않는다는 것은 그들이 주어를 갖지 않고 있거나 (독일어의 경우), 아니면 그것이 어떤 문법/통사적 역할을 하는가 (한국어의 경우)에 주된 원인이 있다. $\ast$ 비교 대상의 양쪽은 생략가능성, 즉 원자가 요구에 대한 자유/비구속성을 누린다. 핵(성분), 즉 독일어의 부정형 및 분사 그리고 한국어 동사는 혼자 남을 때까지 생략이 계속될 수 있다. 이러한 의미에서 부정성은 <비한정성/비구속성>과 관련된 것 같으며, 반면에 정동사의 특성은 <한정성/구속성>과 관계되어 있다. $\ast$ 원자가 요구/충족에 대한 자유/비구속성은 한국어 동사/술어가 문장 끝에 고정되어 있다는 사실은, 직접 또는 간접으로 본동사 앞에 놓여 있어야 되는 모든 문장성분과 부문장 때문에, 즉 한국어의 전면적인 전위수식 현상으로 흔히 큰 부담/복잡함을 야기한다는 데에 그 원인이 있다. 이러한 상황에서 동사는 가능한 한 그의 문장성분을 줄이려 한다. 통사적으로 보장되어 이미 있으니 말이다. 그래서 한국어 동사의 부정성은 일종의 부담해소 대책으로 간주될 수 있을 것이다. $\ast$ 두 비교 대상에서의 핵 및 최소문장 가능성은 역시 원자가에 대한 비구속성에서 비롯된다. $\ast$ 우리 한국인이 빨리 말할 때 흔히 범하는 부정성으로 인한 인칭변화에서의 오류는 무엇보다도 정형성/제한성을 지닌 독일어 정동사가 인칭 변화하는 데 반해 한국어에서는 부정성/비구속성을 지닌 동사가 그것과는 무관한 페 기인한다. 동사의 속성을 철저히 분석함으로써 이런 과오를 극복해야 할 것이다. 한국어 동사의 부정성은 지금까지 거의 연구되지 않았다. 이 문제는 또한 지속적으로 수많은 다른 자연어들과의 비교분석을 통해 관찰돼야 할 것이다. 이 논문이 이런 연구와 언어습득을 위한 작업에 도움이 되기를 바란다.

The purposes of this study is to investigate spatial structure characteristics of earthen walled fortresses based on topography, which are locational and Plane morphology, Cross sections of earthworks. Target areas of this study are 37 earthen walled fortresses which are designated as cultural properties. This study is conducted with methodologies of literature review, field investigation, investigation on topography materials and relation analyses of topography&spatial structure. The results from study on spatial structure of earthen walled fortresses are as follows. First, Earthen walled fortresses on flat topography were adjacent to water systems like rivers or streams. Plane morphology showed regular shapes. The cross section morphology presented trapezoid the most with earthworks of which outer and inner walls were built. Second, More than 70% of earthen walled fortresses on hilly topography had water system within close range of approximately 1.5km. Plane morphology was mainly with more than 73% of irregular types. Cross sections of earthworks were of morphology with more than 86% of bordered type and another type leaning against existing topography like mountains. Third, 59% of earthen walled fortresses in mountain areas had water system within their close range, which indicated that they depended on external water system less than those with hilly topography. Plane morphology was mainly with more than 67% of irregular types. Cross sections of earthworks were of monoslope method with more than 94% of bordered type and another type leaning against mountains.

목적 : 방사선치료기술이 날로 발전함에 따라 방사선치료계획시스템에 대한 주기적인 정도관리의 필요성은 증대하고 있으나, 국내 실정에 적합한 표준화된 정도관리절차서가 없는 실정이다. 따라서 본 연구에서는 방사선치료계획용 시스템에 대한 정도관리용 고체팬톰을 제작하여 주기적인 정도관리 활용 및 절차서를 제시하고자 한다. 대상 및 방법 : 체윤곽 보정을 위한 삼각기둥 모형 (30cm$\times$30cm$\times$5cm, 30cm$\times$15cm$\times$5$\times$) 및 정형ㆍ부정형, 불균질 측정이 가능한 물등가고체팬톰을 제작하였고, 컴퓨터단층촬영(AcQsim)을 통해 영상을 얻었으며, RTPS(AcQplan)에 입력하여 영상 내 기준점에서의 선량값을 계산하였다. RTPS를 통해 계산된 값의 평가를 위해 동일한 조건하에서 각 기준점에 대한 실제 측정을 이온함을 이용하여 측정하였다. 평가 항목으로는 정방형 조사면, 부정형 조사면, 쐐기 조사면, 불균질 물질 보정, 사방향 조사 등에 대해서 알고리즘별로 수행하였다. 결과 : RTPS를 이용하여 계산된 값과 실제 측정한 값을 비교하여 RTPS의 정확성을 평가한 결과로 합성의 불확도 허용 기준 (3%), 선속 중심축 상에서의 허용 기준 (2%) 등, 선진 각국 및 각 학회에서 권고하고 있는 허용 범위 내에서 잘 일치하였다. 결론 : RTPS는 측정된 심부선량과 선량분포 등 물리적인 인자에 의존하는 제한성이 있고, 실제로 선량계산 알고리즘과 기하학적 변화에 따라 계산값과 측정값 간에 차이가 발생할 수 있었다. 실제 인체의 체윤곽 불균일성과 불균질성을 모사한 팬톰을 제작하여 이용함으로써 다양한 RTPS간의 비교를 통한 치료 선량의 정확성을 평가하고, 방사선 치료의 원활하고 정확한 수행을 위해 실용적이고, 보편적인 치료계획 시스템의 정도관리 방법과 절차서를 수립하는데에 유용할 것으로 사료된다.

Skeletal Cl III malocclusion is an orthopedic appliance mainly used for growing children with maxillary undergrowth, which largely entails skeletal Cl III malocclusion. It improves anterior crossbite and maxillary position and thus, enables patients to attain favorable Profile but often involves unfavorable profile with protrusive upper and lower lips. Therefore, if orthodontists have knowledge of which condition helps obtain favorable occlusion and profile, they are able to predict the prognosis and limitation of the treatment. This study was done in order to help obtain favorable Profile after treating growing skeletal Cl III children. In the study, we classified childern into two groups, the one with favorable profile(Group 1, n=12) and the other with unfavorable profile(Group 2, n=14) and, with retrospective study using pre- and post-treatment lateral cephalogram, drew the following conclusions. 1. As patients had more serious labioversion of upper incisors, they were more unlikely to have favorable profiles after the treatment. Protrusion of prosthion, which was related with maxillary incisors, also affected profiles. 2. As the NL-ML angle before the treatment was small, it was more likely to get favorable profile. 3. As the degree of lower lip protrusion was high, it was likely to have bialveolar protrusion after the treatment. 4. As the degree of downward and backward rotation of mandible was high, it was likely to get unfavorable profile.

This paper describes the case of a 50-year-old female with a Class II malocclusion who presented with severe bimaxillary protrusion and generalized alveolar bone loss due to adult periodontitis. The treatment plan consisted of extracting both upper and lower first premolars and periodontal treatment. Anterior segmental osteotomy(ASO) of the mandible and upper anterior segment retraction using compression osteogenesis after peri-segmental corticotomy(Speedy orthodontics) was performed. Correct overbite and overjet, facial balance, and improvement of lip protrusion were obtained. However, a slight root resorption tendency was observed on the lower anterior dentition. The active treatment period was 9 months and the results were stable for 27 months after debonding. This new type of treatment mechanics can be an effective alternative to orthognathic surgery.

Purpose: Isolated capitellar fractures are rare, intra-articular fractures requiring an aggressive management regimen. Review the outcome after open reduction and internal fixation of the capitellar fractures. Materials and Methods: From 1998 to 2004, 4 patients with displaced fractures of the humeral capitellum were treated by open reduction and internal fixation of the capitellar fragments with cannulated screws. By use of the criteria of Bryan and Morrey et al, there were 3 type I fractures, 1 type III fracture. A lateral approach was used. The elbows were immobilized postoperatively for 4 to 28 days We evaluated the range of motion, stability, and pain using the criteria of Mayo score. Results: The follow-up period ranged from 12 to 36 months (mean, 15months). Three patients had a stable, pain-free elbow with good range of motion at follow-up. One patient with a neglected capitellar fracture have felxtion cpontracture of 40 degrees with 100 degrees of further felxion(total arc: 60) due to poor compliance to the postoperative rehabilitation. All fractures healed, and there was no evidence of avascular necrosis or degenerative change. Conclusion: Capitellar fractures, rare in case, gave a good result after open reduction and simple internal fixation with cannulated screws without any problem.

Proximal humerus fracture can be defined as a fracture that occurs in the surgical neck or proximal part of the humerus. Despite the appropriate treatment, however, various complications and sequelae can occur, and the treatment is quite difficult often requiring surgical treatment, such as a shoulder replacement. The classification of sequelae after a proximal humerus fracture is most commonly used by Boileau and can be divided into two categories and four types. Category I is an intracapsular impacted fracture that is not accompanied by important distortions between the tuberosities and humeral head. An anatomic prosthesis can be used without greater tuberosity osteotomy. In category I, there are type 1 with cephalic collapse or necrosis with minimal tuberosity malunion and type 2 related to locked dislocation or fracture-dislocation. Category II is an extracapsular dis-impacted fracture with gross distortion between the tuberosities and the humeral head. To perform an anatomic prosthesis, a tuberosity osteotomy should be performed. In category II, there are type 3 with nonunion of the surgical neck and type 4 with severe tuberosity malunion. In type 1, non-constrained arthroplasty (NCA) without a tuberosity osteotomy should be considered as a treatment. On the other hand, reverse shoulder arthroplasty (RSA) should be considered if types 1C or 1D accompanied by valgus or varus deformity or severe fatty degeneration of the rotator cuff. In general, the results are satisfactory when NCA is performed in type 2 sequelae. On the other hand, RSA can be considered as an option when there is no bony defect of the glenoid and a defect of the rotator cuff is accompanied. In type 3, it would be effective to perform internal fixation with a bone wedge graft rather than shoulder replacement arthroplasty. Recent reports on the results of RSA are also increasing. On the other hand, recent reports suggest that good results are obtained with RSA in type 3. In type 4, RSA should be considered as a first option.
