Angiosarcoma is a rare tumor that account for less than 1% of all sarcomas.Although hepatic angiosarcoma usually presents with unspecific symptoms, it rapidly progresses and has high mortality.We report case primary manifested as recurrent hemoperitoneum.

Objective Hepatologists and colonoscopists often hesitate to perform a colonoscopic polypectomy in patients with chronic liver disease (CLD), especially those cirrhosis, because of the risk postpolypectomy bleeding (PPB). We aimed investigate incidence factors delayed PPB after CLD. Materials methods In total, 152 CLD who underwent from December 2005 2012 were retrospectively reviewed. Results Cirrhosis was identified 80 (52.6%) patients. During study period, 442 polyps removed developed 14...

전 지구적으로 발생하고 있는 잦은 기상이변과 기후변화의 가속화로 자연재해 발생빈도 및 피해규모는 증가하고 있다. 이러한 기상이변은 우리나라 또한 예외가 아니며 최근 한반도에서 발생한 적설로 인하여 많은 인명과 재산피해가 본 연구에서는 기상청에서 제공하는 KMA-RegCM3 모형과 기후변화 시나리오를 바탕으로 관측 미래의 기온과 강수량를 이용하여 적설량을 산정하였다. 대표 기상관측소 18개 대상지점의 목표기간별(목표기간 I: 1971~2010년, 목표기간 II: 2011~2040년, III: 2041~2070년, IV: 2071~2100년) 일 토대로 빈도별(50년, 80년, 100년, 200년) 확률적설량을 미래 적설량 예측은 기상인자들의 복잡한 비선형 조합으로 발생하기 때문에 적설량에 영향을 미치는 강수량의 과정들을 고려할 수 신경망 모형을 예측 구성하였다. 기후변화에 따른 확률적설량의 평균 증감률은 I을 기준으로 약 6~18%정도 감소하며, II, III, IV로...

적설량은 기상변수들의 복잡한 비선형 조합으로 발생하기 때문에 적설량에 영향을 미치는 온도, 강수량, 적설량의 과정들을 고려할 수 있는 신경망 모형과 통계적 기법인 다중회귀 모형을 이용하여 적설량 예측 구성하였다. 관측시점부터 1999년까지의 관측된 기온, 적설량을 지점별로 예측모형을 구성하였고, 2000년부터 2011년까지의 지점별 강수량을 통해 산정과 관측 자료와의 통계분석을 실시하였으며, 이 중 상관계수와 수정결정계수가 높은 채택하였다. 채택된 모형의 상관계수는 0.700~0.949로 매우 관계를 나타냈으며, 수정결정계수는 41.7%~89.8%로 총 변동을 설명하였다. 대부분의 지점에서 적용성이 우수한 것으로 나타났으나, 학습기간에서 관측자료의 부족, 예측기간 학습되지 않은 극값의 발생 등에 의해 울진, 대전, 부산, 목포의 경우 보다 더 높게 산정되었다. 본 연구를 통하여 기온 및 이용한 예측이 가능함을 확인하였으며, 기상자료의 비선형과정을 적용하는 것이 기존의 예측보다...

Selecting an optimum number of calibration sites for hydrological modeling is challenging. Modelers often spend a lot time and effort on trial error because there no guide. We propose novel entropy method to automate the selection combination sites. To illustrate, proposed applied using discharge data from one river basin in Korea. First, different combinations discharge-gauging were grouped based maximum information estimated by method. Then, model was set up study calibrated estimating...

HISTORICIZING TERESA: REFLECTIONS ON NEW DOCUMENTS REGARDING SOR TERESA DE CARTAGENA Dayle Seidenspinner-Núñez University ofNotre Dame Yonsoo Kim Boston College While Teresa de Cartagena's works have received an increasing amount of critical attention in recent years, her enigmatic figure remains veiled speculation. Since Francisco Cantera Burgos definitively confirmed kinship witii the powerful and influential Santa Maria/Cartagena family 1952-daughter Pedro Cartagena, niece ofAlonso...

The aim of this study is to evaluate the filtering techniques which can remove noise involved in time series. For this, Logistic series chaotic and radar rainfall are used for evaluation low-pass filter (LF) Kalman (KF). added by considering level filtered LF KF reduction. analysis performed correlation coefficient, standard error, attractor, BDS statistic from chaos theory. result clearly showed that better tool than removing noise. Also, we evaluating reduction capabilities KF. In case, it...

Generalized likelihood uncertainty estimation (GLUE) is one of the widely-used methods for quantifying in flood inundation mapping. However, subjective nature its application involving definition measure and criteria defining acceptable versus unacceptable models can lead to different results bounds. The objective this paper perform a sensitivity analysis effect choice measures cut-off thresholds used selecting behavioral non-behavioral GLUE methodology. By using dataset reach along White...

This paper proposes the method of risk assessment to minimize damages caused by natural disasters (typhoons, heavy rain, snow, strong winds, high waves) and establish systematic disaster prevention measures for 228 local governments. In this study, consists four main factors: hazard, exposure, vulnerability, reduction. These factors are evaluated in terms a disaster's indicators probability, consequentiality, reducibility, respectively. The evaluation criteria hazard exposure have been...

Although prolonged post-operative ileus (PPOI) is an important factor for the length of hospital stay, there still a lack effective predictive and therapeutic methods PPOI. Previous studies reported that increased inflammatory markers, such as C-reactive protein (CRP) level neutrophil to lymphocyte ratio (NLR), are associated with malignancies. The aim our study elucidate association between peri-operative markers PPOI after gastrectomy gastric cancer.We enrolled patients who received cancer...

The storage function model (SFM) is a rainfall–runoff widely used in Korea for flood forecasting and warning systems. traditional equations parameter estimation are based on observed data under limited conditions, so it difficult to sensitively consider the factors affecting actual runoff. aim of this study develop synthetic SFM that useful ungauged watersheds, through 35 000 applications distributed kinematic wave (KWM) virtual watersheds. equation developed was applied 101 events 16 basins...

The aim of this study is to identify and evaluate chaotic behavior in hydro-meteorological processes. This poses the two hypotheses First, assume that input data significant factor provide characteristics output data. Second, system itself For solving issue, time series such as precipitation, air temperature, discharge, storage volume were collected Great Salt Lake Bear River Basin, USA. period approximately one year extracted from original using wavelet transform. generated summation sine...

The medieval writer Teresa de Cartagena was the first Castilian who bequeathed us two complete works: Arboleda los enfermos and Admiraçión operum Dey. Because of complexity her work, critics have researched still debate intellectual spiritual paths. In this article, I will dedicate a space to argue against scholars consider mystic. Although used language that appears mystic, ambiguity discourse on sanctity lay in lack discursive tools, helped cope misogynist society. Therefore, purpose...

본 연구에서는 자연생태계가 잘 발달되어 있는 남한강의 비내섬 습지에 대해 유황분석을 실시하였고, 그 결과를 토대로 HEC-RAS 모형과 RAS Mapper를 이용하여 침수심을 산정하였다. 이를 통해 침수심에 영향을 많이 받는 식물의 서식환경을 분석하였다. 버드나무 군락은 침수가 발생하지 않는 지역부터 0.8 m까지 침수심이 발생하는 지역, 물억새군락은 0.4 m의 쑥-망초군락과 달뿌리풀군락은 0~0.4 그리고 환삼덩굴군락은 0~0.8 지역에서 서식하는 것으로 분석되었다. 연구는 유황에 따른 대한 식생서식환경을 분석한 식생을 고려한 인공습지 조성이나 하천설계에 있어 기초적인 자료가 될 기대되며, 보다 더 정확한 연구를 위해서는 식생의 장기모니터링을 통한 D/B 축적 및 효과적인 수위-식생 연계분석 방법론 개발에 연구가 필요할 판단된다. In this study, we analyzed the flow duration of Binae wetland, which has a...

Self-expandable metallic stents (SEMSs) are typically inserted in patients with unresectable malignant biliary obstruction. However, SEMSs susceptible to occlusion. To overcome this issue, we developed a large-bore, dumbbell-shaped, fully covered SEMS (FCSEMS-L) and compared its efficacy safety those of conventional FCSEMS (FCSEMS-C) obstruction.Patients distal obstruction were retrospectively enrolled between January 2011 February 2021. All underwent endoscopic insertion FCSEMSs. Recurrent...
