Among the traditional painting conservation based on textiles, the material used to reinforce the defective part must be similar to the artifact under various conditions, such as weaving, thickness, and strength, as well as the visible texture. If those conditions are not satisfied, a visual difference may occur and cause secondary damage due to strength differences. ‘Ma(麻)’ - includes ramie, hemp, flax, jute and so on - is a base material that is not difficult to see in traditional paintings and has excellent durability and strong strength. Because of this property, when a new fabric is used as a material for reinforcing the defective part, it provides a cause of damage due to differences in physical properties, and it is difficult to trim the defective part due to strong durability. In particular, securing flexibility as a filling material for hanging scroll is one of the most important conditions to be prioritized, and the same applies not only to 'ma' but also to silk-based traditional paintings. In the case of silk, in order to solve this problem, artificial deterioration studies using electro beam and ultraviolet-c have been conducted, and deteriorated silk textiles are used for conservation of traditional paintings. However, no artificial deterioration studies have been conducted on plant fibers such as 'ma'. This study is focus on ramie textiles among 'ma' and conduct to produce artificial deteriorated ramie textiles for conservation of ramie-based traditional paintings. Ultraviolet-C were irradiated by several time zones to deteriorate the ramie textile, and the obtained specimens were analyzed. And then trimmed, and colored to evaluate whether they could be applied to actual artifact conservation. As a result of the experiment, there was no significant change in appearance, such as weaving distortion, when visually observed. Although no noticeable change could be observed in microscopic examination, but it was found that impurities remaining at the time of ramie weaving were removed. In the color difference measurement, it was found that excessive yellowing did not occur even if it was deteriorated to the extent that molding was easy. regardless of the degree of deterioration, coloring proceeded without difficulty. So it was judged that deterioration ramie textiles were suitable for application to conservation of paintings. Based on the experiment, a deterioration ramie textiles were produced and used for the conservation of the 《Hae-Dong Painting Collection》, owned by the Kansong Art and Culture Foundation. 직물 바탕 회화 문화재 보존처리 중 결손부 메움에 쓰이는 재료는 육안으로 보이는 질감뿐만 아니라 직조·두께·강도 등 여러 가지 조건이 유물과 유사해야 한다. 앞서 언급한 조건들을 충족하지 않을 경우 시각적 이질감이 들고 강도 차이에 따른 2차 손상 원인이 될 수 있다. 조건을 따지지 않고 재료를 사용하는 경우 오히려 유물이 손상되는 원인이 될 수 있다. 모시는 회화 문화재에서 어렵지 않게 볼 수 있는 바탕재로 내구성이 뛰어나고 강도가 강한 특징이 있다. 이러한 성질 때문에 결손 부분 메움 재료로 새 직물을 쓰는 경우 물성 차이로 인한 손상 원인을 제공하며, 강한 내구성 때문에 결손 부분 성형에 어려움이 있다. 특히 권축류(券軸類) 메움 재료로서 유연성 확보는 무엇보다도 우선시되어야 할 중요한 조건 중 하나이며, 모시뿐만 아니라 견(絹) 바탕 회화 문화재에도 동일하게 적용된다. 견의 경우 이 문제를 해소하기 위해 전자선 및 자외선 등을 이용한 인공 열화 연구가 이루어져있으며 문화재 보존처리에 열화견이 쓰이고 있다. 그러나 모시와 같은 식물성 섬유에 대한 인공 열화 연구는 이루어지고 있지 않다. 본 연구는 모시 바탕 회화 문화재 보존처리를 위한 인공 열화 모시 제작을 위해 진행되었다. 단파장 자외선(Ultraviolet-C, UV-C)을 여러 시간대로 조사하여 모시를 열화하고, 얻은 시편은 분석 및 성형·채색 실험을 거쳐 실제 유물 보존처리에 적용 가능한지 평가하였다. 실험 후 육안 관찰 시 직조가 뒤틀리는 현상과 같은 외관상 변화가 크지 않았다. 현미경 촬영에서 두드러지는 변화를 관찰할 수는 없었으나 모시 제직 당시 남아있던 불순물이 제거된 것을 알 수 있었다. 색차 측정에서는 성형이 용이한 정도로 열화가 되어도 지나친 황변이 일어나지 않는다는 결과를 얻었다. 열화 정도와 관계없이 채색은 어려움 없이 진행되어 열화 모시가 유물에 적용하기 적합하다고 판단하였다. 실험을 바탕으로 간송미술문화재단 소장 《해동명화집》의 보존처리에 열화 모시를 제작해 사용하였다.

Characterization of cellulosic aerogel from microcrystalline cellulose

이신아,두예슬,정명준,강규영 한국공업화학회 2014 한국공업화학회 연구논문 초록집 Vol.2014 No.1

Since cellulose is a natural polymer and an abundant resource, technology based on cellulose has been developing in a wide field from in a primary industry to materials for aerospace. Among cellulosic biomass materials, cellulose aerogel is one of the fascinating products and has been actively studied. In this research, cellulosic aerogel structure from microcrystalline cellulose (MCC) was studied. Cotton linter was chosen for starting material in order to prepare MCC. Hydrolyzed cotton linters, MCCs were dissolved in LiCl/DMAc and Ca(SCN)2, respectively, to produce wet-gel. In result, it was found that MCC can cause increased density, destroyed micro-pore structure and uniformed distribution.

A gastrointestinal stromal tumor (GIST) is the most common mesenchymal tumor of the gastrointestinal tract and expresses CD117, a c-kit proto-oncogene, which can be detected immunohistochemically. We reported a GIST of the rectum of a 61-year-old-woman who had visited emergency room complaining of constipation over one week. Upon rectal examination, a round hard mass was palpated. Colonoscopy showed a 7×5 cm sized protruded lesion with surface ulceration on a rectum, adjacent the anus. And abdomen computed tomography revealed the soft tissue mass compressing anterolateral wall of the rectum and these findings suggest possibility of rectal submucosal tumor such as GIST. The patient had been treated with a ultra anorectal anastomosis with loop ileostomy. Immunohistochemical studies on the surgically resected specimen showed c-kit (+) and CD34 (+). The final diagnosis was a GIST of the rectum. She was grouped into high risk and she has been given adjuvant chemotherapy with Imatinib.

Cellulose is the renewable, biodegradable and abundant resource and is suggested as an alternative material to silica due to the high price and environmental load of silica. The first step for cellulose aerogel production is to dissolve cellulose, and hydrated calcium thiocyanate molten salt is one of the most effective solvents for preparing porous material. Cellulose aerogels were prepared from dissolved cellulose samples of different degree of polymerization (DP) and drying methods, and tested with shrinkage, density and mechanical strength. Supercritical CO2 dried cellulose aerogels shrank less compared to freeze-dried cellulose aerogels, whereas the densities were increased according to the DP increases in both cellulose aerogels. Furthermore, scanning electron microscope (SEM) images showed that the higher DP cellulose aerogels were more uniform with micro-porous structure. Regarding the mechanical strength of cellulose aerogels, supercritical CO2 dried cellulose aerogels with higher molecular weight were much more solid.

혈액형 부적합 신장이식의 현재와 과제

이신아,강덕희 이화여자대학교 의과학연구소 2015 EMJ (Ewha medical journal) Vol.38 No.1

Kidney transplantation is the best treatment for end-stage renal disease patients. However, the relative shortage of organs for transplantation has led to ABO-incompatible kidney transplantation as an accepted method to expand the pool of kidney donors. Recent advances in immunosuppression and antibody removal methods have made ABO-incompatible kidney transplantation more feasible, and have increased the opportunities for patients to receive kidney transplantation, as well as for special patients with ABO-compatible donor. Indeed, the outcome of ABO-incompatible kidney transplantation has shown remarkable developments and is now comparable to that of ABO-compatible kidney transplantation during last decade. However, there are still some uncertain issues to be addressed in ABO-incompatible kidney transplantation. In this article, we reviewed the current status and protocol of ABOincompatible kidney transplantation and listed the concerns to be addressed in near future.
