The diffuse form of supravalvar aortic stenosis represents a surgical challenge when the ascending aorta, aortic arch, proximal descending thoracic aorta and arch arteries are involved. It can be treated by a variety of surgical approaches. We report a case of severe diffuse supravalvar aortic stenosis combined with an aortic valve anomaly and occlusion of the right coronary artery ostium in a 14-year-old boy with Williams syndrome. We enlarged the aortic root(Nick's procedure), ascending aorta, aortic arch, proximal descending thoracic aorta, and innominate artery with patches and replaced aortic valve with 19 mm St. Jude valve. Deep hypothermic circulatory arrest and retrograde cerebral perfusion were used during repair of the arch and arch artery.

Tracheoinnominate artery fistula is a rare but a catastrophic complication after tracheostomy or tracheal reconstruction. We experienced two cases of tracheoinnominate artery fistula after tracheal reconstruction and tracheostomy. The first patient was a 11 year old girl with cerebral arteriovenous malformation who maintained tracheostomy for 6 months before undergoing tracheal reconstruction. Three days after tracheal reconstruction, massive bleeding occurred through the intubation tube. She underwent emergency reoperation of repair the innominate artery with 5-0 Prolene and reconstruction of trachea. She died of bleeding 3 days after the reoperation. The second patient was a 68 year old man who underwent right upper lobectomy due to lung cancer. After operarion MRSA Pneumonia was developed and tracheostomy was performed 10 days after intubation. Twelve days after tracheostomy, massive bleeding occurred and emergency operation of ligation of innominate artery was performed. He died of sepsis 7 days after reoperation.

The animation "Gloom" based on the low poly art expresses the intention of the production by expressing an music as an animation. The paper describe the production process including the modeling, rigging, animation, and rendering. Furthermore, the production process for pure creative animation with client's intention was also considered. Therefore, it can provide guidelines for pure creators who do similar creative work.

신인 작가나 무명작가들이 전시회를 개최하는 데에 드는 비용적 제약을 비롯하여, 관람객들에게 따르는 공간적 한계점을 보완하기 위해 기획된 가상 전시 공간 플랫폼이다. 가상현실과 증강현실의 발전이 급증하고 있는 가운데, 차세대 ICT 기술을 갤러리라는 항목과 접목시켜 관람객과 전시자 모두가 만족할 수 있는 공간을 구축하였다. VR을 활용한 가상 전시공간을 통해 실감 나는 전시회장 환경을 체험할 수 있는 것은 물론, 증강현실을 통해 마음에 드는 작품을 자신만의 공간에 띄워보며 분위기를 조성할 수 있다. 또한, SNS와 즐겨찾기 기능을 추가해 사용자의 선호도를 파악하고 편의성을 도모하였다. 단순 전시회장에 국한되는 것이 아니라, 대학생들의 졸업 작품 전시회나 박물관 등에도 활용할 수 있는 여지가 충분할 것으로 보여진다.

The major etiology of superior vena cava (SVC) syndrome is malignancy. Radiologic endovascular intervention is the treatment of choice for patients with SVC syndrome due to malignant disease, which is unresponsive to radiation therapy and chemotherapy. However, it is not clear whether endovascular intervention can replace open surgery as the primary method of management of benign SVC syndrome. We report two cases of benign SVC syndrome resulting from dialysis catheters placed in the central veins. One patient underwent bypass surgery between innominate vein and right atrium by expanded polytetrafluoroethylene. Another patient had large thrombi in SVC and other central veins. We removed them under cardiopulmonary bypass to prevent pulmonary embolism, and SVC was repaired and augmented by autologous pericardium. Prompt symptomatic relief and angiographic improvements of collateral flow were achieved in both patients.

Recently, I presented Gagok(歌曲) Collection Yeong-eon永言 to learned circles. Yeong-eon is very similar to Yukdang-version六堂本 CheongGuYeongeon靑丘永言. Compared with Cheong- Yuk, it is the same age or little bit early time of Cheong-Yuk in culture Icon. This paper paid attention to the considerable difference between Yeong-eon and Cheong-Yuk in the way of the distribution of Yisakdaeyap二數大 葉's Woo mode羽調 and Ke-myeon mode界面調. There was the way of gathering ‘real name’+‘namelessness’ in Yisakdaeyap, which is the feature of the 18th century Gagok Collection. I found this way just put on the 19th century Gagok Collection way which is the distribution of Yisakdaeyap's 'Woo mode and Ke-myeon mode' in CheongYuk. Then I proved in this paper that the way of gathering Yisakdaeyap in Cheong Yuk didn't correspond to an actual singing in the early 19th century when 'Woo mode and Ke-myeon mode' was fixed. In case of Yeong-eon, however, it was not written any writers' names at all, when it was researched retroactively, I knew it was distributed evenly both the works of 'real name' and 'namelessness' in Yisakdaeyaps 'Woo mode and Ke-myeon mode'. Consequently, I found Yeong-eon is the good Gagok Collection for an actual singing at that time. In addition, there was discord in the mode or key distribution among many Gagok Collections. I found this issue of the application had kept on make Gagok Collections edit during 2 centuries. Because the actual Gagok enjoyment in the specific time is connected the way of the mode application directly.

본 연구에서는 낙동강 하구역 해역에서의 폭풍 해일의 특성 및 이를 고려한 외해 압사파랑특성을 고찰하고 연안사주 전면의 입사파랑과 퇴적 특성과의 상호 관계를 고찰하였으며 천해역의 파랑변형을 예측할 수 있는 다방향 불규칙파 묘형을 구성하고 폭풍 해일고를 수심조건에 고려함으로써 하구역 해역에서의 파랑 변형계산을 2차원 평면수치모의실험을 수행하였다. 낙동강 하구역에서 서측에 위치하는 진우도 전면해역이 무명도 전면해역보다 약 1.0배에서 2.0배 크게 파고분포를 나타내었다. 이는 입사하는 파랑의 공간 분포가 사주전면에서 공간적으로 차이가 남을 나타내는 것으로 사주의 퇴적작용에 영향을 줄 것이라고 판단된다.

This study is to understand Chang-ui construction of the middle Chosun Dynasty through the reconstruction of the blue Chang-ui which was excavated from General Parks tomb. The followings are the results of this study. There are 4 styles in excavated Chang-ui of middle Chosun Dynasty: Two styles seem to belong to the early 17th Century and the other, the late 17th century. The former is classified into 2 styles by the gender of the wearer, the latter is also classified into 2 styles by etiquette of clothing. We can assume that Chang-ui excavated from General Parks tomb was the womans clothing in early 17th century. This Chang-ui(II) differs from other Chang-ui(I) at two points. One is the construction of the trapezoid and triangle gussets on the side seam of clothing. The other is the construction of the narrow width of clothing(23cm). We have found that these two gussets could improve the active aspect of clothing and save materials. It is identified that the green tone was faded from the blue color of Chang-ui according to the calculation of the L*a*b.

Systemic arteriovenous(AV) fistulas are a rare but well-recognized cause of hyperkinetic circulation that, if undetected, may lead to congestive heart failure. We experienced a very rare case of acquired arteriovenous fistula. A 61-year-old female patient presented with congestive heart failure symptoms after percutaneous pinning for right sternoclavicular joint dislocation. We surgically obliterated the fistula between aorta and innominate vein and performed tricuspid annuloplasty for severe tricupid insufficiency simultaneously. She was discharged with complete relief of her symptoms and has been well during 2 years and 6 months follow up.

A 49-year-old female patient who had obstruction of superior vents cave(SVC) with SVC syndrome was successfully managed by bypass operation of superior vents cava with spiral vein graft. A composite spiral vein graft was placed between the right innominate vein and the right atrium to bypass the occluded SVC. The graft was constructed from the patient's own saphenous vein, which was split longitudinally and wrapped around a stent in spiral fashion and the edges of the vein were sutured together to form a large autogenous conduit. The patient was relieved o SVC obstructive symtoms and signs and discharged 21 days postoperatively without any complication.
