The spiral form, which comes from the organic form of natural phenomenon such as growth of creatures, has been used as a factor of formative shape in various fields of art until now. In conjunction herewith, this study intends to discover and express the life force and the formative beauty of natural substances with the organic spiral forms into clothing design, using various creating methods and materials such as Korean traditional paper. The natural substances with the spiral structure, such as seashells, land snails, passion flower, curled flower, growing chart of plants, Impatiens textori was used as subjects of the designs. The seven pieces of work were completed with attempts to develop aesthetic forms through the presentation techniques and methods via restructuring process of simplification, partial transformation and consolidation. Through such process the conclusion of this study is as follows: First, the nature, with unlimited possibilities, could be subject of human formative activities, leading to the creative world of formative art for designers. Second, adaptation of the spiral organic forms of nature into the contemporary clothing designs proved the motif as a source of inspiration of diverse subject, in recognition with its innate formative beauty as well as external shape. Third, design expressions via restructuring process of simplification, partial transformation and consolidation with designer's subjective point of view were adequate for the creations of contemporary fashion designs. Fourth, the Korean traditional paper, as a fine material for various shape according to the handling method, could be used appropriately in the contemporary clothing designs, expressing our aesthetic senses. Fifth and finally, expansion of the realm of formative expression of clothing through the development of possibilities of expression in contemporary clothing would enhance the creative possibilities of clothing design as formative art. In conclusion, the expression of clothing design as formative art was developed on the emphasis of re-creation of natural objects of the organic spiral form. For the future study, the applications of spiral form into everyday clothing designs, consolidating artistic senses and practical senses, are expected as opportunity of proposing developmental possibilities of the contemporary clothing designs.

Chest tube insertion is a common procedure usually done for the purpose of draining accumulated air or fluid in the pleural cavity. Small-bore chest tubes (${\leq}14F$) are generally recommended as the first-line therapy for spontaneous pneumothorax in non-ventilated patients and pleural effusions in general, with the possible exception of hemothoraces and malignant effusions (for which an immediate pleurodesis is planned). Large-bore chest drains may be useful for very large air leaks, as well as post-ineffective trial with small-bore drains. Chest tube insertion should be guided by imaging, either bedside ultrasonography or, less commonly, computed tomography. The so-called trocar technique must be avoided. Instead, blunt dissection (for tubes >24F) or the Seldinger technique should be used. All chest tubes are connected to a drainage system device: flutter valve, underwater seal, electronic systems or, for indwelling pleural catheters (IPC), vacuum bottles. The classic, three-bottle drainage system requires either (external) wall suction or gravity ("water seal") drainage (the former not being routinely recommended unless the latter is not effective). The optimal timing for tube removal is still a matter of controversy; however, the use of digital drainage systems facilitates informed and prudent decision-making in that area. A drain-clamping test before tube withdrawal is generally not advocated. Pain, drain blockage and accidental dislodgment are common complications of small-bore drains; the most dreaded complications include organ injury, hemothorax, infections, and re-expansion pulmonary edema. IPC represent a first-line palliative therapy of malignant pleural effusions in many centers. The optimal frequency of drainage, for IPC, has not been formally agreed upon or otherwise officially established.

샌드박스 게임은 높은 자유도를 기반으로 사용자 스스로 다양한 플레이패턴을 재창조하며 만족을 배가시킨다. 이러한 창조적 과정은 '커스터마이징'과 '행동자율성'을 통한 놀이의 확장성에 기인한다. 이는 즐거움을 느끼는 요소가 과정지향적이라는 말로 대변될 수 있다. 본고는 샌드박스형 게임이 다중경쟁 환경에서 가지는 구조적한계를 규명하고자 한다. 스텐드어론 기반에서는 다양한 커스터마이징을 통한 자유도의 확장성이 유저에게 월드지속성에 강한 동기를 부여한다. 반면 MMORPG와 같은 온라인 샌드박스 게임물에서는 다수유저의 경쟁 우위를 점하고자하는 목적지향적 성향이 샌드 박스형 게임 본연의 자유도와 확장성을 구사할 수 없는 태생적 한계임을 확인하였다. 본 연구에서는 온라인 기반의 샌드박스형 게임의 자유도와 확장성의 효용이 상쇄되는 원인과 성장한계를 옵티멀솔루션 요소에 기인함을 제시할 수 있었다.

Background: Fibrous dysplasia (FD) is characterized by the replacement of normal bone by abnormal fibro-osseous connective tissue and typically treated with surgical contouring of the dysplastic bone. When dysplastic lesions involve occlusion, not only is surgical debulking needed, orthognathic surgery for correction of dentofacial deformity is mandatory. However, the long-term stability of osteotomized, dysplastic bone segments is a major concern because of insufficient screw-to-bone engagement during surgery and the risk of FD lesion re-growth. Case presentation: This case report reviewed two patients with non-syndromic FD that presented with maxillary occlusal canting and facial asymmetry. Le Fort I osteotomy with recontouring of the dysplastic zygomaticomaxillary region had been performed. The stability of osseous segments were favorable. However, dysplastic, newly formed bone covered the previous plate fixation site and mild bony expansion was observed, which did not influence the facial profile. Including the current cases, 15 cases of orthognathic surgery for FD with dentition have been reported in the literature. Conclusion: The results showed that osteotomy did not appear to significantly reduce the long-term stability of the initial fixation insufficiency of the screw to the dysplastic bone. However, based on our results and those of the others, long-term follow-up and monitoring are needed, even in cases where the osteotomized segment shows stable results.

UML 모델을 사용하는 다양한 소프트웨어의 설계 및 구현 환경에서 UML 메타 모델의 규칙을 준수하고, 이를 통하여 확장하면 많은 장점을 가질 수 있다. 하지만 UML 메타 모델은 자체 규모가 점진적으로 방대해지고 있으며 UML 메타 모델을 사용하는 다양한 곳에서 UML 메타 모델의 확장 및 변환을 위해서는 반드시 Profile의 정의를 통하여 다이어그램을 재정립할 필요가 있다. 즉, UML 메타모델을 확장하여 사용하고자 하는 대상에 대하여 요소들만을 추출하여 사용할 필요가 있다. UML 메타모델의 확장과 Profile을 메타 저장소를 기반으로 재정의하여 사용함으로써 UML 모델링 도구나 분석도구를 좀 더 쉽고 빠르게 개발할 수 있고, 이러한 도구를 활용하여 SW 산업에서의 개발 품질을 높일 수 있다. 본 논문에서는 UML 메타모델의 확장을 통하여 Profile을 재정의 하는 알고리즘을 제시하고, 전자정부 표준 프레임워크에 실제로 적용한 결과를 코드 사이즈와 복잡도를 비교하여 향상된 성능을 보여준다.

Purpose: Pnumosinus dilatans is a rare disease that one or more of the paranasal sinuses are dilatated without functional alteration. The most frequently involved sites are frontal and sphenoid sinus. Facial asymmetric contour is the most common signs and nasal obstruction and pain may be combined. The purpose of reconstruction of pneumosinus dilatans is two-fold, to re-establish a permanent pressure equilibrium of sinus and to correct the possible facial deformities. Methods: We present a case of a 24-year-old female with a 7-year history of protrusion of right malar region. Plane radiography and computed tomography detailed an abnormal expansion of the right maxillary sinus without thinning of bony wall, leading to diagnosis of maxillary pneumosinus dilatans. Surgical decompression and maxilloplasty were achieved by ostectomy of anterior wall of maxillary sinus and repositioning of removed bony fragment with miniplate. Results: Post operative course was uneventful without complication and malar height became symmetric by physical and radiologic examination. Conclusion: We corrected successfully pneumosinus dilatans of maxillary sinus by surgical decompression and maxilloplasty. For this case, we reviewed literature related to this topic.

A clinical investigation was reported on 17 cases of spontaneous pneumothorax requiring surgical mana-gement. Males outnumbered females 15:2. Determination of the etiology in this series showed that the majority were pulmonary tuberculosis and paragonimiasis. Several others had pneumonia, lung abscess, cyst and blebs. It is of particular interest that the acute inflammation of respiratory system was younger age group, pulmonary tuberculosis & paragonimiasis were between 2 nd and 3 rd decades, and lung abscess, cyst, blebs were above 4 th decade. Pulmonary tuberculosis was far advanced bilateral and active. The ratio of right to left side was 13:6 and both side involved in 2 cases. In about half cases of patients, above 50%-collapsed lung associated with mediastinal shifting developed. The complications were pleural effusion and bronchopleural fistula. The former was 13 cases [76.4%] in which 3 cases combined with mixed infection, and latter was 5 cases. As the management, 11 cases were subjected to intercostal or rib resection drainage with continuous suc-tion. Among 11 drainage cases, 8 cases were successful in acute stage and 3 cases failed in chronic stage. This faiure was due to interference with re-expansion of collapsed lung for peel formation and broncho-pleural fistula. The open thoractomy was applied in 9 cases, among which primary operation were 5 cases and drainage failure were 4 cases. Among 11 cases subjected to the open thoracotomy, wedged resection was performed in 3 cases including paragonimiatic cyst, and pneumonectomy in 1 case-tuberculosis, and decortication only was performed in 2 cases in paragonimiasis. Decortication & lung resection was carried out in 2 patients among which ruptured lung abscess 1 case and ruptured multiple blebs 1 case. There was no case of death but prognosis of the tuberculosis may be poor because of far advanced bilateral and active pulmonary tuberculosis.
