Gadoxetic acid-enhanced MR and combined MR are more accurate than CT in detecting colorectal hepatic metastases, have an incremental value when added to CT alone for detecting additional metastases, and can be routinely performed in patients with potentially curable hepatic metastases detected with CT.

The presence of a perceptible focal low-attenuation lesion in the pancreas on CT and the reduction in signal intensity of the lesion on the opposed phase of chemical shift MR images are useful for differentiating focal fatty replacement of the pancreas from true pancreatic neoplasm. Therefore, these imaging findings obviate invasive diagnostic procedures and surgery in the care of patients with focal fatty replacement of the pancreas.

MRCP cannot replace ERCP for the diagnostic evaluation of AIP but may deserve to be used when ERCP has been unsuccessful or is difficult to perform.

본 연구의 목적은 청소년 사회참여활동의 잠재유형을 파악하고, 잠재계층분석을 통해 나타난 하위집단별 유형이 공동체 의식에 미치는 영향을 검증하는데 있다. 이를 위하여 한국아동․청소년패널조사(2012) 자료를 이용하여 잠재계층분석과 다중회귀분석을 실시하였다. 먼저, 청소년 사회참여 잠재유형에 따라 구분되는 잠재계층을 추출한 결과 3개의 잠재유형이 도출되었으며, 각 유형이 갖는 특성에 따라 각각 자원봉사활동형, 다(多)참여형, 참여저조형으로 명명하였다. 그 다음으로 다중회귀분석을 통해 청소년 사회참여활동 잠재유형과 청소년의 공동체 의식과의 관련성을 분석한 결과, 참여저조형에 비해 다(多)참여형과 봉사활동형이 공동체의식에 정적 영향을 미치는 것으로 확인되었다. 본 연구결과를 토대로 청소년 사회참여활동 활성화 및 공동체의식을 함양하기 위한 개입방안을 제시하였다.

본 연구는 사회복지사가 경험하는 감정노동의 실체에 대해 Giorgi의 현상학적 연구방법을 활용하여 그 의미를 파악․이해하고자 하였다. 이를 위해 2014년 4월부터 5월까지 서울시 내 종합사회복지관에서 근무하는 경력 2년 이상의 사회복지사 10명을 대상으로 심층인터뷰를 진행하였다. 인터뷰내용은 참여자들의 동의를 바탕으로 녹취하여 기초자료로써 사용하였으며, 분석결과, 사회복지사 감정노동 경험의 구성요소는 ‘클라이언트의 삶이 내게 온다는 무게감’, ‘사회복지사로서 꿈꿔왔던 이상이 현실이라는 벽에 부딪힘’, ‘사회복지사로서의 의미 찾기’, ‘끊임없는 감정컨트롤 상황을 마주대하는 전략’, ‘에너지 고갈로 인해 열정이 사그라듬’, ‘계속되는 적응’등의 6개 중심의미와 15개 하위구성요소로 도출되었다. 이러한 연구결과를 바탕으로 사회복지사의 감정노동과 관련한 정책적․실천적 대안을 제시하였다.

Additional MRI resulted in changes of resectability and treatment modifications in a significant proportion of patients who have potentially resectable state at CT and in prolonged time to liver metastases in patients after curative surgery. Additional MRI to standard staging CT can be recommended for surgical candidates of PDA.

BACKGROUND: Spinal anaesthesia-induced hypotension is frequently reported in patients undergoing caesarean section. Mechanistically, sympathetic blockade reduces the systemic vascular resistance and the left ventricular preload, causing hypotension, which is augmented by aortocaval compression. The corrected blood flow time (FTc) is affected by the preload and is inversely related to the afterload. OBJECTIVE: We hypothesised that the preanaesthetic carotid artery FTc could predict hypotension af

BACKGROUND: Wireless capsule endoscopy allows the identification of small intestinal protruded lesions, such as polyps, tumors, or venous structures. However, reading wireless capsule endoscopy images or movies is time-consuming, and minute lesions are easy to miss. Computer-aided diagnosis (CAD) has been applied to improve the efficacy of the reading process of wireless capsule endoscopy images or movies. However, there are no studies that systematically determine the performance of CAD models

When selecting the nasotracheal tube diameter for nasotracheal intubation, atraumatic introduction of the tube through the nasal passage and a safe location of the tube's cuff and tip should be ensured simultaneously. To maintain safety margin for the tube's cuff and tip from the vocal cords and carina (2 cm and 3 cm, respectively), the maximum allowable proximal-cuff-to-tip distance was calculated as 5 cm less than the measured vocal cords-to-carina distance. The primary aim of this study was t

BACKGROUND AND OBJECTIVES: This study was aimed at assessing left ventricular torsion (LVtor) mechanics using speckle tracking echocardiography (STE), establishing normal reference values of principal LVtor parameters, and analyzing the age-related changes in normal children. SUBJECTS AND METHODS: Eighty children (aged 3 months to 15 years) with normal cardiac function and rhythm were recruited. LVtor parameters including rotations, twist and untwist, torsion, and their rate indices were measure

PURPOSE: We aimed to investigate multimodality imaging findings of intraductal tubulopapillary neoplasms (ITPN) of the pancreas. METHODS: This study was approved by the institutional review board with waived informed consent. A total of eight patients were histopathologically diagnosed with pancreatic ITPN in a single institution over a 6-year period. The imaging findings of dynamic contrast-enhanced computed tomography (CT), magnetic resonance cholangiopancreatography (MRCP), endoscopic ultraso

Abstract Implantable biosensors play a critical role in healthcare and medical research by enabling real‐time monitoring of physiological signals with high precion. Compared to non‐invasive biosensors, implantable biosensors offer superior fidelity by minimizing external noise and ensuring direct contact with target tissues. However, conventional implantable biosensors, often composed of intrinsically rigid materials such as silicon and metals, suffer from mechanical mismatches with soft biologi

Background: Carbapenem-resistant Pseudomonas aeruginosa (CRPA) and Acinetobacter baumannii (CRAB) are the leading causes of nosocomial infections. A rapid and sensitive test to detect CRPA and CRAB is required for appropriate antibiotic treatment. We optimized a loop-mediated isothermal amplification (LAMP) assay to detect the presence of blaVIM-2, blaIMP-1, and blaOXA-23, which are critical components for carbapenem resistance. Methods: Two sets of primers, inner and outer primers, were manuall
