Background and Objectives:The burden of heart failure has increased in Korea.This registry aims to evaluate demographics, clinical characteristics, management, long-term outcomes patients hospitalized for acute (AHF).Subjects Methods: We prospectively enrolled a total 5625 consecutive subjects AHF one 10 tertiary university hospitals from March 2011 February 2014.Descriptive statistics were used determine the baseline characteristics study population compare them with those other...
During the end-of-life stage, patients suffer from multiple symptoms or impairments of altered body systems. This study examined nurses' knowledge care and also relationship between their characteristics.This was a descriptive, correlational using convenience sample 368 Korean registered nurses working in cancer units, general wards, intensive units university health system. Twenty questions Palliative Care Quiz for Nursing (PCQN) were used to examine care.The mean score on PCQN 8.95...
To investigate the difference between ionic and electronic conductors as infiltrates in solid oxide fuel cells (SOFCs), high-throughput high-performance finite element simulations were carried out on 51 different cathode microstructures. Five backbones, reconstructed from a commercial SOFC, infiltrated computationally with varying number densities of nanoscale electronically or ionically conducting particles. Local electrochemical quantities computed within volumetric meshes that represent...
High performance computing simulations of Cr-poisoning are used to develop systematic trends for overpotential driven degradation modes in microstructurally resolved fuel cell cathodes. Oxygen reduction and chromium oxide deposition at triple phase boundaries (tpbs), species transport, numerically computed within 19 microstructures (103 µm3 domains) over a range operating conditions. Three primary input parameters drive degradation: tpb density the microstructure ρtpb, normalized...
Background North Korean defectors (NKDs) have often been exposed to traumatic events. However, there few studies of neural alterations in NKDs with post-traumatic stress disorder (PTSD) and complex PTSD (cPTSD). Aims To investigate cPTSD, a specific focus on resting-state functional connectivity networks, including the default mode network (DMN). Method Resting-state was assessed using brain magnetic resonance imaging three groups NKDs: without PTSD, cPTSD. Statistical tests were performed,...
Myocardial ischaemia is a leading cause of acute heart failure (AHF). However, optimal revascularisation strategies in AHF are unclear. We aimed to compare two strategies, coronary artery bypass graft (CABG) and percutaneous intervention (PCI), patients with AHF.Among 5625 consecutive enrolled prospectively the Korean Acute Heart Failure registry from March 2011 February 2014, 717 who received CABG or PCI during index hospitalisation for were included this analysis. compared adverse outcomes...
Background: The International Trauma Questionnaire (ITQ) is a self-report assessment focused on the core features of Post-Traumatic Stress Disorder (PTSD) and complex (CPTSD). It consistent with organizing principles 11th revision to WHO's Classification Diseases (ICD-11). Since 1990s, number North Korean defectors (NKD) entering South Korea escape human rights violations has been increasing rapidly, 33,815 NKD settled by 2021. government faces an important challenge in supporting...
Loneliness negatively predicts post-traumatic growth (PTG) among North Korean defectors (NKD), one of the representative groups refugees. Additionally, evidence also suggests that females, who account for 70% NKDs entering South Korea, are vulnerable not only to past trauma but current acculturation stress and loneliness affected by neighborhood social cohesion. This study explores whether mediating effect on relationship between PTG was moderated cohesion female NKDs. In this study, data...
In this study, we investigated the composition of an electrolytic Fe phosphide at different synthesis temperatures. We found that ratio in electrodeposit increases with temperature, whereas oxygen content introduced into by atmospheric oxidation decreases. The aim study was to identify reason for effect. For purpose, and P electrodeposits prepared temperatures analyzed depth. addition, types ratios phases were considered. It proved increase a significant amount reacted form phases,...
Abstract Observations indicate a low obesity prevalence among North Korean Defectors (NKRs), who fled to South Korea, attributed undernourishment prior their arrival. With an aging NKR demographic, there’s growing concern over chronic disease management, including hypertension. Previous studies reported high or comparable of elevated blood pressure NKRs, yet the influence mental health on hypertension has been underexplored. Given rates trauma-related conditions and depression within this...
Using a large-scale, experimentally captured 3D microstructure dataset, we implement the generative adversarial network (GAN) framework to learn and generate microstructures of solid oxide fuel cell electrodes. The generated are visually, statistically, topologically realistic, with distributions microstructural parameters, including volume fraction, particle size, surface area, tortuosity, triple phase boundary density, being highly similar those original microstructure. These results...
Abstract Purpose Extant literature shows that loneliness negatively predicts post-traumatic growth (PTG) among North Korean defectors (NKD). Female NKD are more vulnerable to various traumatic experience in the entire process from escaping Korea and entering South Korea. Evidence also suggests of migration settlement causes acculturation stress could be affected by neighborhood social cohesion. This study explores mediating effect on relationship between PTG, moderating cohesion female NKD....
