Impact of perception of COVID-19 on NPI, job satisfaction, and customer orientation: Highlighting three types of NPIs for the airline industry.

Without vaccines or pharmaceutical treatments for a viral pandemic, non-pharmaceutical interventions (NPIs) such as washing hands and wearing masks are likely the most effective ways to control infections at airports and on airplanes. Although the aviation market is a major entry point for viruses, little is known about how flight attendants view the risk of COVID-19 and whether they follow individual-organizational-governmental NPI protocols. Guided by protection motivation theory (Rogers, 1975), this study proposed an NPI model tailored specifically to the airline industry and examined how an extended NPI would affect job satisfaction and customer orientation of Korean flight attendants (n = 371).

Environmental effects of the technology transformation from hard-disk to solid-state drives from resource depletion and toxicity management perspectives.

Solid-state drives (SSDs) are used as data storage systems in various electronic devices in place of hard-disk drives (HDDs) due to their higher speed and durability and lower noise and power consumption. Although SSDs have these advantages, the environmental consequences of the technology transformation from HDD to SSD need to be examined from resource depletion and toxicity management perspectives because most electronic components and devices contain rare, precious, and toxic metals. Thus, the objective of this study was to assess and compare resource depletion and toxicity potentials from metals in an HDD and an SSD on a same capacity basis.

Free-breathing dynamic contrast-enhanced MRI of the abdomen and chest using a radial gradient echo sequence with K-space weighted image contrast (KWIC).

Objectives: To evaluate the feasibility of free-breathing, dynamic contrast-enhanced (DCE) MRI of the abdomen and thorax using the radial-gradient-echo sequence with k-space weighted image contrast (KWIC) reconstruction.

Methods: Institutional review board approval was obtained. Fourteen patients underwent free-breathing radial DCE-MRI.

Quantitative color mapping of the arterial enhancement fraction in patients with diffuse liver disease.

Objective: The purpose of this study was to determine whether color mapping of the arterial enhancement fraction of the liver with multiphasic liver CT can depict the hemodynamic changes associated with diffuse liver disease.

Materials And Methods: A total of 142 patients (59 men, 83 women; mean age, 50 years) with diffuse liver disease and 25 patients acting as controls (11 men, 14 women; mean age, 54 years) were classified into three groups: controls (n = 25), patients with acute liver injury (no underlying chronic liver disease [n = 25], acute exacerbation of chronic liver disease [n = 17]), and patients with chronic hepatic injury (hepatitis [n = 25]; cirrhosis [n = 75], 25 each with Child-Pugh A, B, and C disease). The quantitative arterial enhancement fraction color map of the liver was generated from routine multiphasic CT images with prototype software.

Percutaneous sacroplasty with the use of C-arm flat-panel detector CT: technical feasibility and clinical outcome.

Purpose: Sacroplasty for sacral insufficiency fractures (SIFs) has been performed mostly under computed tomography (CT) or fluoroscopy guidance. The purposes of this study are to describe technical tips and clinical outcomes of sacroplasty under C-arm flat panel detector CT (C-arm CT) guidance, and to compare the cement distributions shown on C-arm CT with those on multi-detector CT (MDCT).

Materials And Methods: This study consisted of patients who underwent sacroplasty for SIF using C-arm CT from May 2006 to May 2009.
