김혜선,김기봉,황호영,장형우,박규주 대한흉부외과학회 2012 Journal of Chest Surgery Vol.45 No.3

Background: Median sternotomy can weaken the upper abdominal wall and result in subxiphoid incisional hernia. We evaluated risk factors associated with the development of subxiphoid incisional hernias after coronary artery bypass grafting (CABG). Materials and Methods: Of 1,656 isolated CABGs performed between January 2001 and July 2010, 1,599 patients who were completely followed up were analyzed. The mean follow-up duration was 49.5±34.3 months. Subxiphoid incisional hernia requiring surgical repair developed in 13 patients (0.8%). The hernia was diagnosed 16.3±10.3 months postoperatively, and hernia repair was performed 25.0±26.1 months after the initial operation. Risk factors associated with the development of subxiphoid incisional hernia were analyzed with the Cox proportional hazard model. Results: Five-year freedom from the hernia was 99.0%. Univariate analysis revealed that female sex (p=0.019), height (p=0.019), body surface area (p=0.046), redo operation (p=0.012), off-pump CABG (p=0.049), a postoperative wound problem (p=0.041), postoperative bleeding (p=0.046), and low cardiac output syndrome (p<0.001) were risk factors for the development of the hernia. Multivariable analysis showed that female sex (p=0.01) and low cardiac output syndrome (p<0.001) were associated with subxiphoid hernia formation. Conclusion: Female sex and postoperative low cardiac output syndrome were risk factors of subxiphoid hernia. Therefore, special attention is needed for patients with high-risk factors.

철제유물의 부식억제를 위한 부식억제제에 관한 연구

김혜선,허윤현,김수기 한국문화재보존과학회 2014 보존과학회지 Vol.30 No.1

철제유물의 안정화처리는 부식인자 용출 처리하는 방법에 중점을 두고 있으나 탈염 처리 등 부식인자의 제거 여건이 안 갖춰진 경우 부식억제제를 투입하여야 한다. 하지만 철제유물에 적용하는 대표적인 부식억제제가 없으며 이에 대한 연구도 부족한 실정이다. 따라서 본 연구에서는 철제유물의 부식억제제의 실효성을 검증하고 이에 접합한 부식억제제를 제시하는데 그 목적이 있다. 본 연구에서 부식억제제는 BTA, DAN과 MEA, TEA를 선정하였고 분극 시험, 접촉각, XPS 등의 분석기기를 이용하여 비교 실험을 하였다. 그 결과 분극시험과 접촉각 실험에서 모든 시편이 소수성의 피막을 형성하며 부식저항성이 높아지는 현상을 통해 부식억제제의 실효성을 검증하였다. 또한 부식억제제 의 농도가 높을수록 부식억제 효과가 좋아지는 것을 확인할 수 있었다. BTA는 XPS실험에서 부식성물질을 차단하는 성분인 C-H 결합 peak의 함량이 높게 검출되었으며 분극시험에서 부식전위가 매우 높게 측정되어 철제에도 부식억제 효과를 보이는 것으로 판단된다. 에탄올아민에서 TEA보다는 MEA가 더욱 우수하였으며 MEA는 소수성 피막을 형성 하여 야외 철제유물의 부식억제제로 제시할 수 있다.

김혜선,정지현,김승현 한국고분자학회 2021 한국고분자학회 학술대회 연구논문 초록집 Vol.46 No.2

Nanoelectrode and its array in electrochemical applications can provide greater advantages such as fast response times, enhanced mass transport and sensitivities compared with its corresponding planar or micro-electrodes. Therefore, the fabrication of nanoelectrode arrays has attracted increasing attention, and has been developed by applying various techniques. In this work, the gold nanoelectrodes coated with vertically-oriented cylindrical nanopores are fabricated for the sake of electrochemical dopamine sensing. The structure of periodic nanoporous membranes was generated by the self-assembly of block copolymers (BCPs). The effects of thickness of films, scan rate, concentration of diffusion species, and pH of electrolytes were indicated by the array of gold nanoelectrodes. The morphologies of membranes were characterized by AFM and SEM, and the electrochemical analysis of nanoelectrodes from nanoporous membranes was optimized by CV measurements.

자궁경부 세포진에서 ASCUS 진단의 세분화 - "ASCUS, R/O HSIL" : 세포학적 소견 및 조직학적 상관성

김혜선,김복만,김의정,김희숙,Kim, Hye-Sun,Kim, Bock-Man,Kim, Yee-Jung,Kim, Hy-Sook 대한세포병리학회 2002 대한세포병리학회지 Vol.13 No.1

Cytologic and histopathologic features and human papillomavirus (HPV) DNA detection associated with 101 cervicovaginal smears which are ciassified as 'atypical squamous cells of undetermined significance, rule out high grade squamous intraepithelial lesion(ASCUS, R/O HSIL)' were reviewed and compared to 89 smears of 'ASCUS, not otherwise specified(NOS)'. Cytologic fieatures of ASCUS, R/O HSIL included atypical single small cells(36.6%), hyperchromatic tissue flagments(35.6%), atypical metaplastic cells(18.8%), endometrial cell-like clusters(5.9%), and atypical parakeratotic cells(3.0%). A final diagnosis of HSIL on biopsy was assigned to 47(54.0%) of 87 women with ASCUS, R/O HSIL and to 13(14.6%) of 89 women with ASCUS, NOS (p=0.000). There was no difference in HPV DNA detection late between ASCUS, R/O HSIL and ASCUS, NOS smears. These data suggest that subclassification of ASCUS is helpful to manage patients because ASCUS, R/O HSIL is more often associated with an underlying HSIL on biopsy. Therefore, women with ASCUS, rule out HSIL should be actively managed with colposcopic examination.

Purpose : To assess the usefulness of cardiac MR imaging (MRI) in the diagnosis of acute myocardial infarction and in the assessment of myocardial viability in comparision with T1-201 SPECT. Materials and Methods : We retrospectively studied 17 patients who complained of chest pain and dyspnea with cardiac MRI . The patients were evaluated for the presence or absence of high signal intensity on T2-weighted image (T2wI), abnormal wall motion on 2D-FIESTA, perfusion defect on Gd-DTPA enhanced T1WI, and delayed myocardial enhancement on 15-minutes delay Gd-DTPA enhanced T1WI. The results were correlated with the images on T1-201 SPECT, taken at rest and stress, through which reversibility of perfusion defect was assessed. Results : Both cardiac MRI and T1-201 SPECT proved to be useful methods for diagnosing acute myocardial infarction. In order of decreasing correspondence, T2WI, T1-201 SPECT, delayed enhancement study, and wall motion images all showed significant statistical correlation with the clinical diagnosis of myocardial infarction. Perfusion MRI, on the other hand, showed no significant statistical difference was found between T1-201 SPECT and cardiac MRI. The results on T2WI showed high accordance with those on Tl-201 SPECT, while delayed myocardial enhancement and wall motion studies showed no agreement with Tl-201 SPECT. Conclusion : Cardiac MRI is useful method for diagnosis of acute myocardiac infarction. With respect to the assessment of myocardial viability, the results obtained on cardiac MRI showed high agreement with those on Tl-201 SPECT. However, further study is necessary at this point for standardization and establishment of the methods for assessing myocardial viability on cardiac MRI.
