CT Angiography, MR Angiography, and Their Combined Use for Detection of Unruptured Intracranial Aneurysms: Comparison with Digital Subtraction Angiography and 3-dimensional Rotational Angiography.

Purpose: To compare the diagnostic accuracy of CT angiography (CTA), MR angiography (MRA), and their combined use for detecting unruptured intracranial aneurysms (UIAs).

Methods: Between September 2019 and August 2023, 235 patients suspected of having UIA underwent CTA, MRA, and digital subtraction angiography (DSA)/3-dimensional rotational angiography (3DRA). Two neuroradiologists retrospectively reviewed these images for UIA presence.

Pulse Shape Discrimination of n/γ in Liquid Scintillator at PMT Nonlinear Region Using Artificial Neural Network Technique.

Reactor-emitted electron antineutrinos can be detected via the inverse beta decay reaction, which produces a characteristic signal: a two-fold coincidence between a prompt positron event and a delayed neutron capture event within a specific time frame. While liquid scintillators are widely used for detecting neutrinos reacting with matter, detection is difficult because of the low interaction of neutrinos. In particular, it is important to distinguish between neutron (n) and gamma (γ) signals.

Topic Modeling of Nursing Issues in the Media During 4 Emerging Infectious Disease Epidemics in South Korea: Descriptive Analysis.

Background: Emerging infectious disease disasters receive extensive media coverage and public attention. Nurse burnout and attrition peak during health crises such as pandemics. However, there is limited research on nursing issues related to repeated emerging infectious disease crises over time.

Enhancing lactic acid tolerance in Fructilactobacillus sanfranciscensis via adaptive evolution for sourdough fermentation applications.

Fructilactobacillus sanfranciscensis is extensively used in the food industry, notably for sourdough fermentation; however, its mass production is hindered by growth inhibition due to lactic acid accumulation in the medium. This study aimed to enhance the acid tolerance of F. sanfranciscensis SPC-SNU 70-4 via adaptive laboratory evolution (ALE) to improve its viability as an industrial sourdough starter.

[An Exploratory Study on Non-Contact Nursing Experiences of Clinical Nurses during the COVID-19 Pandemic].

Purpose: This study aimed to understand the non-contact nursing experiences of clinical nurses during the COVID-19 pandemic.

Methods: A qualitative research design applying thematic analysis was used. The participants were purposive sampled from three institutes: a tertiary hospital, a general hospital, and a residential treatment center in Seoul.
