      • 세계문화유산 한국 성곽 건축물을 활용한 패션소품 디자인 개발

        송재민,최종명,김지영 한국감성과학회 2017 춘계학술대회 Vol.2017 No.-

        본 연구는 우리나라의 정체성과 고유성을 잘 드러내 주고 있는 문화 아이콘으로 한국의 문화유산 중 유네스코 세계문화유산에 등재되어 세계적으로 탁월한 가치를 인정받는 건축물 문화재 중에서 성곽 건축물인 화성과 남한산성을 선정하여 문화재의 원형 이미지를 한글 글자꼴과 융합하는 방법을 고안하여 스카프와 넥타이 등 패션소품의 디자인 개발에 초점을 두어 진행하였다. 성곽 건축물과 한글 글자꼴을 융합하기 위하여 건축물의 기하학적인 형태와 조화를 이룰 수 있도록 고딕체의 글자꼴을 활용하여 가로, 세로의 비율과 굵기의 변화를 적용하여 입체감과 통일감을 느낄 수 있도록 글자꼴을 개발하였으며, 성곽 건축물의 외형 이미지를 라인작업으로 추출하여 모티브 디자인을 개발하였다. 추출된 건축물의 외형 모티브에 개발된 글자꼴의 자음과 모음을 활용하여 형태와하거나 자음만을 축소, 확대하여 성곽 건축물의 이미지를 형태화하여 표현하였다. 이와 같이 개발된 화성과 남한산성의 모티브 디자인을 세계 국기의 주요 색상을 활용하여 패션소품 디자인을 개발하였다. 스카프 아이템의 컨셉은 문화재의 이미지를 통해서 한글의 정체성을 느낄 수 있도록 클래식한 이미지에 중점을 두어 표현하였으며, 넥타이 아이템의 컨셉은 한글의 자음과 모음, 문화재이미지를 패턴화한 모티브를 적용하여 현대적이고 모던하면서도 우리의 고요한 정서를 느낄 수 있도록 중점을 두어 표현하였다.

        Parenteral, non-live rotavirus vaccine: recent history and future perspective

        송재민 대한백신학회 2021 Clinical and Experimental Vaccine Research Vol.10 No.3

        Since the widespread introduction of oral and live attenuated rotavirus vaccines around the world in 2009, the impacts of disease burden and the effects of disease reduction in developing countries have been proven. However, in low and middle-income countries, the vaccine efficacy is somewhat lower than in developed countries due to differences in nutritional conditions, microbial environments of individuals, and other factors. In addition, as oral, live vaccines have been found to be associated with rare but serious side effects, the development of a next-generation vaccine with safety, improved effectiveness, and ease of storage is currently underway. New vaccine strain developed by the Centers for Disease Control and Prevention in the United States are undergoing preclinical testing of efficacy, antigen dose, and administration route in the form of a heat-treated inactive vaccine, and a recombinant protein-based trivalent subunit vaccine developed by the Program for Appropriate Technology in Health is undergoing clinical trial in phase III. Several research groups are also developing non-replicating protein-based rotavirus vaccines using virus-like particles and nanoparticles. This review provides a brief overview of the development status and technology of parenteral, non-live rotavirus vaccines worldwide.

        Electrooptical Threshold Behavior of Electroconvection in Twisted Nematic Liquid Crystal Cells

        송재민,최규진,곽진석,손영구,허종훈 한국물리학회 2017 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.70 No.3

        In this paper, the electrooptical threshold behavior of electroconvection caused by the electrohydrodynamic instability in twisted nematic liquid crystal cells is presented. We observed the electroconvection optically and analyzed the change in the electrical threshold behavior according to the twisted angles in twisted liquid crystal cells in the conduction region that shows the Williams domain, which is one of the most basic patterns for electroconvection in an anisotropic fluid like liquid crystals (LCs). As a result, we confirmed that in the low frequency conduction regio where the Williams domain appears, the threshold voltage decreased as the twist angle increased even though the twist structure enhanced the effective viscosity in liquid flow. The increase in the twist angle may shorten the charge relaxation time because a twisted LC is a structure that more easily accumulates electrical charges on local curvatures.

        간장의 횡격막 탈장에 의한 Budd-Chiari 증후군: 1예 보고

        송재민,윤중원,김재욱,정우경,정희선,김주형,최준호,김승호 대한영상의학회 2007 대한영상의학회지 Vol.56 No.1

        Budd-Chiari syndrome is an uncommon disorder, and it is caused by obstruction of the hepatic venous outflow or inferior vena cava above the hepatic vein. It may result from a large number of conditions, including primary congenital obstructions of the hepatic veins or inferior vena cava by webs or bands. Secondary causes include trauma, polycythemia vera, chronic leukemia, pregnancy, tumors and use of oral contraceptives. No definitive etiologic factors have been identified in two thirds of all cases (1-3). We recently experienced a case of Budd-Chiari syndrome caused by diaphragmatic hernia in 21-year-old man. Postoperative follow up CT showed normal venous flow after reintroduction of the liver into the abdominal cavity and closure of the diaphragm defect. Budd-Chiari 증후군은 드문 질환으로서 간정맥 또는 하대정맥의 위치에서 간정맥 유출의 폐쇄를 특징으로 하는 여러 질병을 포함하여 통칭하는 질환이다. 원인으로는 일차성으로 막과 밴드에 의한 선천성 간정맥 유출의 폐쇄와 이차성으로 종양에 의한 간정맥 침범 또는 압박, 외상, 임신, 경구 피임제, 만성백혈병 등을 들 수 있으나 최근에 영상학적 진단의 발달에도 서구에서는 아직도 2/3 정도는 원인 미상으로 보고되고 있다(1-3). 임상증상으로 간비대, 복통, 복수 등이 관찰될 수 있으나 항상 관찰되는 것은 아니며 흔히 비특이적 간문맥압 상승, 황달, 정맥류 출혈을 보일 수 있다(1, 2). 저자들은 최근 간장의 횡격막 탈장에 의한 Budd-Chiari 증후군 1예를 경험하였고 이는 국내외적으로 드물게 보고되고 있어 흉부사진과 전산화단층촬영 소견을 보고하는 바이다.

        유경 횡복직근피판술 후 발생한 부분 피판괴사 및 지방괴사의 넓은등근피판을 이용한 재건 치험례

        송재민,양정덕,정기호,정호윤,조병채,이상윤 대한성형외과학회 2009 Archives of Plastic Surgery Vol.36 No.1

        Purpose: The transverse rectus abdominis musculocutaneous(TRAM) flap is the most commonly used autogenous tissue flap for breast reconstruction. Postoperatively, partial flap loss or fat necrosis are relatively common and it may result in a smaller breast volume with marked contour irregularities. These defects are not easy to reconstruct with local tissue rearrangement or with breast implants. The current authors present the results of 2 patients who underwent Latissimus dorsi(LD) flap reconstruction to correct partial flap or fat necrosis that developed after TRAM flap breast reconstruction. Methods: Case1: A 50-year-old woman with left breast cancer visited for breast reconstruction after radical mastectomy. Initially, breast reconstruction with pedicled TRAM was performed. Postoperatively partial flap necrosis was developed. Secondary breast reconstruction using LD flap was done. Case2: A 51-year-old woman with left breast cancer visited for breast reconstruction after radical mastectomy. Initially, breast reconstruction with pedicled TRAM was performed. Postoperatively fat necrosis was developed. Secondary breast reconstruction using LD flap was done. Results: Secondary breast reconstruction using LD flap survived completely and produce successful reconstruction. There was no significant complication in both patients. Conclusion: LD flap provides sufficient, vascularized skin and soft tissue. The flap can be molded easily to replace deficient tissue in all areas of the breast. These attributes make it an ideal candidate for salvage of the partially failed TRAM flap breast reconstruction.
