본 연구는 국내 브랜드 ‘마임'의 뷰티와 연계한 뷰티 쇼룸을 제안함에 있어서 공간속에 오감을 담아내는 일련의 프로세스를 밝히는데 목적이 있다. 이는 브랜드가 소유하고 있는 다양한 감각과 가치가 결여된 채 시각적 요소만이 담긴 브랜드 뷰티 쇼룸이 대다수를 차지하는 오늘날, 이에 대한 문제를 해결하기 위해 ’융합 연출 디자인'적 시점에서 폭넓게 바라보고 브랜드의 정신과 오감의 결합을 통해 이를 해결하고자 하였다. 이에 본 연구는 2017년 3월~6월 15주간 숙명여대 환경디자인학과 <융합연출 디자인>수업에서 진행된 수업의 결과물로서 산학 연계된 화장품 브랜드의 쇼룸디자인 개발 프로세스를 제안한다. 또한 본 연구의 범위는 오감을 담고 있는 뷰티 쇼룸(4D)이 되기까지의 과정 전체로 한다. 그 결과, 마임 뷰티쇼룸은 공간 디자인과 오감을 융합하여 영상에서 공간에 이르기까지 오감의 조화와 브랜드의 정신을 녹여내고 확장시켰다. 끝으로 본 연구는 뷰티 쇼룸 공간 디자인을 제안함에 있어서 오감을 활용하여 통합된 시점에서 그래픽·제품·공간을 개발 및 제시한 것에 의의가 있다. 또한 향후 이와 관련된 쇼룸 공간 개발에 있어서 기초 자료로 활용될 것으로 기대된다.

하대정맥의 막성폐쇄로 인한 Budd-Chiari 증후군은 비교적 드문 질환으로 알려져 있다. 저자들은 우상복부 동통을 주소로 내원한 환자에게 방사선학적 검사와 임상적으로 확진된 하대정맥의 막성폐쇄에 의한 Budd-Chiari 증후군 1례를 경험하였기에 문헌고찰과 함께 보고 하고자한다. The Budd-Chiari syndrome is a rare, often fatal illness resulting from hepatic venous outflow occlusion. It occurs secondary to intrinsic vascular thrombosis, tumor invasion, or rarely a congenital web. We report a case of primary Budd-Chiari syndrome with membranous obstruction of inferior vena cava, with a brief review of literature.

The incidence of hematologic disorders in patients with Down's syndrome is significantly increased, about 14∼30 - fold higher than in general population and includes neonatal transient abnormal myelopoieis and acute leukemias. The age of onset of leukemia in Down's syndrome is peaking first in the newborn period and then under 4 years of age. Down's syndrome with acute leukemia above the age of 20 is very rare and it's treatment oucome is unclear. The treatment of Down's syndrome with leukemia has been controversial because of toxicity and associated congenital cardiac and other abnormalities. But if treated adequately, children with Down's syndrome show a favorable response to anti-leukemia therapy. A 24-year-old man with Down's syndrome was first seen for the evaluation of anemia and thrombocytopenia. The peripheral blood morphology and bone marrow study revealed acute myelogenous leukemia, cytogenetic study of bone marrow showed trisomy 21. Beacuse of his sicioeconomic condition and medical abnormalities including deafness, visual loss, he was treated with low dose subcutaneous cytosine arabinoside(Ara-C) for 11 days. Complete remission was obtained after 37 days. The complete remission lasted for 5 months. He subsequently relapsed, and died 6 months later.

Acute torsion of the ovary and ovarian mass is a recognized surgical emergency, but rarely has the diagnosis been made preoperatively on the basis of imaging studies. The sonographic findings in 14 cases of surgically proven torsion of the ovary and ovarian mass are described. Mostly cystic ovarian mass, engorged vessel, dilated uterine tube, beak-like echo(torsion site), smooth mass wall thickening an free-fluid collection in cul-de-sac are described. More significant in terms of specificity were the demonstration in 6 cases(42.9%) of the smooth mass wall thickening and in 8 cases(57.1%) of a free fluid in the cul-de-sac. We report the sonographic findings of ovary and ovarian mass torsion that may suggest the preoperative diagnosis of this condition.

A retrospective review of 22 burst fractures of the thoracolumbar spine was performed to define the radiographic features found on CT and plain radiography. Characteristic components of the injury include : 1. Male to female ratio was 2.7 : 1, and the most prevalent age was 21 to 40 years. 2. Multiple level injuries were 6 cases (27.3%), and the most common cause of injury was fall down(14 cases, 63.6%). 3. The most cammon location was L1(45.5%) 4. The most common pattern of the retropulsed fragment in burst fracture was single midline fragment type(14 cases, 63.6%) and the most common type of burst fracture was classical form(10 cases, 45.5%). 5. Posterior element involvement of vertebra was seen in Ⅱ cases(50%) and the most common finding was laminar fracture in 9 cases. 6. The degree of anterior wedging above the 50% in height of vertebral body was in 4 cases (18.2%). 7. Degree of spinal canal narrowing and degree of neurological impairment is not directly correlated.

The purpose of this study was to investigate the acute (4 hours) and repeated-dose (6 hours a day, 5 days a week, 4 weeks) toxic effects of I -hexene on Sprague- Dawley (SD) rats which were treated by inhalation. The results were as follows; I. The median lethal concentration (LC_(50)) was estimated 52,694 ppm (confidence limit 95%; 49,494~55,447 ppm) in acute inhalation. Abnormal clinical signs related to the l-Hexene were not observed with the acute inhalation dose. Gross findings of necropsy revealed on evidence of specific toxicity related to the 1-hexene, II. By repeated inhalation exposure the body weight of male were more or less reduced by the dose of 2,500 ppm and 5,000 ppm compared with control group. However there were no significant variation hematology and blood biochemistry for the exposed rats compared with the control rats. Abnormal clinical signs and gross findings of necropsy related to the 1-hexene were not shown. In conclusion when we exposed I-hexene to SD rats for 4 weeks, 5 days per week, 6 hours per day, the Lowest observed effect level (LOEL) was over 2,500 ppm and Non observed effect level (NOEL) was below 500 ppm.

This study started from the worry how the students who had been accustomed to uniform thoughts to solve problems by themselves and question how them to develop their ability to express themselves with deep thoughts. Since we realized that writing expression was the most proper way to solve above mentioned problems, the purpose of this study was to find a solution to problems and propose actual and realistic plan to teach writing expression. Through this process, students developed synthetical and deeper ability to think such as ability to analysis, criticize, observe and think logically. It would be better for their social life and establishing their sense of values.
고속전철 Catenary/Pantograph계의 동적응답에 대한 수치해석
최연선,정대현 成均館大學校 科學技術硏究所 1991 論文集 Vol.42 No.1
To increase the velocity of high speed train, electric power collection through pantograph from trolley wire of should be guaranted. As the velocity increase, there are lots of possibility of separation between pantograph and trolley wire due to the mutual dynamic behaviors. However, the complexity of actual Catenary system makes almost impossible to find dynamic responses analytically. In this respect a numerical method is developed to calculate the dynamic responses of Catenary/Pantograph system using central difference method. And the dynamic characteristics of Catenary/Pantograph are investigated as the design parameter variation.
