A study of the electromagnetic interference shielding effectiveness of nickel-plated Carbon fibers/Epoxy composites

김윤섭,박수진 한국공업화학회 2019 한국공업화학회 연구논문 초록집 Vol.2019 No.1

In this study, an electroless method was used to obtain good electromagnetic interference shielding efficiency (EMI-SE) of Ni-P/Carbon fibers/epoxy composites. Carbon fibers (CFs) were Ni-plated chemically to enhance the EMI-SE of Nickel-Carbon fibers (Ni-CFs)/epoxy composites. The surface properties of the Ni-CFs were characterized by scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS), and X-ray diffraction (XRD). The EMI-SE of the Ni-CFs/ epoxy was tested by electromagnetic interference (EMI) shielding analyzer. The EMI-SE of Ni-CFs/epoxy was enhanced compared to that of as-received CFs/epoxy. As a result, the electroless Ni-CFs/epoxy composite shows good electrical conductivity and shows the effect of good electromagnetic shielding. The Ni-CFs can lead to EMI-SE improvement due to the EMI absorption behavior of the Ni particles.

Single-cell and spatial sequencing application in pathology

김윤섭,최진용,이석형 대한병리학회 2023 Journal of Pathology and Translational Medicine Vol.57 No.1

Traditionally, diagnostic pathology uses histology representing structural alterations in a disease’s cells and tissues. In many cases, however, it is supplemented by other morphology-based methods such as immunohistochemistry and fluorescent in situ hybridization. Single-cell RNA sequencing (scRNA-seq) is one of the strategies that may help tackle the heterogeneous cells in a disease, but it does not usually provide histologic information. Spatial sequencing is designed to assign cell types, subtypes, or states according to the mRNA expression on a histological section by RNA sequencing. It can provide mRNA expressions not only of diseased cells, such as cancer cells but also of stromal cells, such as immune cells, fibroblasts, and vascular cells. In this review, we studied current methods of spatial transcriptome sequencing based on their technical backgrounds, tissue preparation, and analytic procedures. With the pathology examples, useful recommendations for pathologists who are just getting started to use spatial sequencing analysis in research are provided here. In addition, leveraging spatial sequencing by integration with scRNA-seq is reviewed. With the advantages of simultaneous histologic and single-cell information, spatial sequencing may give a molecular basis for pathological diagnosis, improve our understanding of diseases,

멜라닌의 광열전환효과를 이용한 전분 기반 생분해성 소재의 약물방출 특성

In this work, functional aspirin (ASP) incorporated biodegradable materials for transdermal drug delivery system were prepared using mungbean starch (MS), polyvinyl alcohol (PVA), sodium benzoate (S), xylitol (XL), and melanin (MEL). In addition, physical properties, photothermal conversion effect, and ASP release properties for prepared functional ASP incorporated biodegradable materials were investigated. Prepared biodegradable materials was analyzed using a Field emission scanning electron microscope (FE-SEM) and Fourier transform infrared spectrophotometry (FT-IR). Phototheramal conversion effect and ASP release properties were evaluated with NIR laser (1.5W/cm2) irradiation time. Results of photothermal conversion effect with NIR laser irradiation indicated that the temperature increase of MEL added biodegradable materials were about 3.5 times higher than MEL non-added biodegradable materials. ASP release ratio(%) of MEL added biodegradable materials with NIR laser irradiation were about 1.5 times faster than MEL non-added biodegradable materials. From the results, prepated functional biodegradable materials are expected to be applied as biomedical material for acute antipyretic, painkiller and cardiovascular disease treatment.

S-151 간에 발생한 양성 신경초종 1예

김윤섭,박주환,이준수,이혜영,권오상 대한내과학회 2016 대한내과학회 추계학술대회 Vol.2016 No.1

서론: 신경초종(Schwannoma) 는 신경세포의 피막을 형성하는 방추형 세포로 구성된 종양이며 대부분 양성이다. 신경초종의 발생연령은 보통 30 ~ 50 대 사이이며 그 외의 연령에서도 발생할 수 있다. 말초 신경에서 기원하는 종양으로 신체의 어느 부위에서도 발생이 가능하나 대부분은 두부, 경부, 그리고 사지의 굴곡 부위에서 발생한다. 소화관 이나 후 복막강에서도 드물게 발생할 수 있지만 간에서 생기는 경우는 아주 드물다. 전 세계적으로 11 예의 증례 보고가 있으며, 국내에서는 2008년도에 발표된 1예의 보고가 있다. 저자는 간 실질에 발생한 신경초종 1예를 보고한다. 증례: 68세 남자 환자가 직장 용종 절제술을 받았고 조직검사 결과 고분화 이형성이 확인되어 시행한 복부 전산화 단층 촬영에서 3×2 cm의 간 종괴가 우연히 발견되어 정밀 검사를 위해 전원되었다. 평소 고혈압으로 약물 복용 중이었으며 간염이나 다른 간질환을 진단받은 병력은 없었다. 환자의 사회력이나 가족력에서 특이사항이 없었다. 입원 당시 활력징후는 혈압 120/70 mmHg, 맥박 78회/분, 호흡 12회/분, 체온 37.0℃였다. 전신상태 양호하였고 의식도 명료하였으며 결막과 공막 모두 정상이었다. 흉부 진찰에서 호흡음 깨끗하였고 심장박동도 규칙적으로 뛰며 잡음은 없었다. 복부 진찰에서 팽만감을 보이지 않았고 장음도 잘 청진되었으며 압통이나 반발 압통도 없었다. 간 종대나 비장 종대도 없었고 복부 전반에서 만져지는 종괴는 없었다. 경부나 액와 등 전신에서 특별하게 촉지되는 림프절 종대 소견은 없었고 피부에서도 이상병변은 관찰되지 않았다. 일반혈액검사는 혈색소 15.2 g/dL, 백혈구 6060/mm3, 혈소판 259,000/mm3이었다. 혈액화학검사에서 총 단백 7.0 g/dL, 알부민 4.3 g/dL, 총 빌리루빈 0.4 mg/dL, 알칼리 포스타파제 67 IU/L, AST 21 IU/L, ALT 21 IU/L, BUN 23.8 mg/dL, 크레아티닌 1.0 mg/dL였다. 종양 표지자는 α-FP 2.70 ng/mL 로 정상이었고 HBsAg 음성, anti-HBs 양성, anti-HCV 음성이었다. 간 전산화단층촬영에서 간좌엽에 장경 3.5cm의 조영증강이 잘 되지 않는 종괴가 있었고 종괴 근처에 커진 림프절이나 다른 이상 소견은 관찰되지 않았다. 간 자기공명영상에서 3.5cm 의 조영증강이 되는 저밀도의 종괴로 확인되었다. 초음파 유도하 조직검사를 시행하였고 추가로 시행한 면역조직화학검사에서 S-100 단백 양성이었고 Actin, CD34, Desmin 모두 음성으로 확인되어 신경초종으로 진단할 수 있었다.

金時習 晩年期의 內面意識에 관한 小考 - 關東日錄·溟洲日錄의 詩들을 중심으로 -

김윤섭 서울대학교 규장각한국학연구원 2010 한국문화 Vol.52 No.-

This study discussed Kim Si-seup’s inner consciousness in his late years with focus on the contents of the poems in Gwandongilrok and Myeongjuilrok which were divided into three major parts. The two books above provide a look into his life after he restarted wandering around Gwandong region at the age of around fifty. First, the study examined how much grief and regret he felt over himself who could not lead a settled life, living away from society. In the works lamenting over his fate to wander around, he repeatedly demonstrate extreme departures from his usual style, frequently expressing reckless and self-defensive feelings. Second, the study explored how his ambition to distinguish himself based on the practical values of Confucianism and his strong aspiration to participate in society are reflected in his reminiscent, retrogressive poems at the time. The works which explicitly demonstrate his obsession to practical values and the attendant frustration starkly contrast with the works telling of his desire to transcend the mundane world. Third, the study examined the works mentioned above, one of the major three parts, that show how much he yearned for an aloof and reclusive life free from all of secular obsessions, wished to roam the nation freely and sought to lead such life. Various aspects of his inner consciousness and sentiments shown though each of the three parts is understandable when considering what he experienced. However,it can not be denied that they contain quite contradictory elements. This study tried to help to grasp Kim Si-seup’s inner consciousness and sentiments by classifying and explaining the inconsistent contents of the poems he wrote in his late years and shedding light on the parts that are related but also have contradictory aspects.
