This study aimed to analyze the design of cervical collar devices for elderly patients with central cord syndrome during physical therapy-based rehabilitation and to summarize related patient needs. To design a cervical collar device that met patient needs, a physician and patients who had worn a cervical collar for more than three months were both interviewed to collect opinions from a profess...

Effective and safe monitoring techniques are needed by U.S. land managers to understand free-roaming horse behavior and habitat use and to aid in making informed management decisions. Global positioning system (GPS) and very high frequency (VHF) radio collars can be used to provide high spatial and temporal resolution information for detecting free-roaming horse movement. GPS and VHF collars ar...

BACKGROUND Dry Eye Syndrome (DES) is a broad spectrum of uncomfortable ocular conditions that are caused by reduced production of tears or an increased tear evaporation rate. This study evaluated the relationship between symptoms of DES and occupational characteristics to identify the occupation-dependent differences in the prevalence of symptoms of DES using the Korean National Health and Nutr...

This study was performed to determine the differences in occupational injuries and illnesses between white-collar and blue-collar workers and to estimate the magnitude of the underreporting of these injuries and illnesses in Korea. Two datasets were used. One was a cohort established in the Gyeongin area with workers who underwent mandated health examinations, and the other was the National Hea...

PURPOSE The purpose of this trial was to evaluate crestal bone level changes radiographically in a standardized fashion over a period of 12 months in humans for implants with a 0.7-mm machined collar (implant type A) versus type B implants with a 1.5-mm machined collar. MATERIALS AND METHODS Twenty-five patients with multiple missing teeth in posterior sectors were randomly assigned to one of...

BACKGROUND According to the guidelines for treatment of multiple trauma patients, immobilization of the neck and neck collar fixation are essential. However, following neck collar fixation patients usually experience dyspnea. Some studies have found that neck collar fixation can lead to decreased pulmonary volumes, yet there have been no studies on the effect of neck collar fixation on patient ...

Very little is known on white-collar crime and how it differs to other forms of offending. This study tests the hypothesis that white-collar criminals have better executive functioning, enhanced information processing, and structural brain superiorities compared with offender controls. Using a case-control design, executive functioning, orienting, and cortical thickness was assessed in 21 white...

the efficiency of a collar in reducing the scour depth around circular and rectangular piers is studied at different flow intensities (ratio of upstream shear stress to sediment critical shear stress). rectangular piers aligned with the flow as well as skewed at 5º, 10º, 20º were examined. previous studies had shown that with collar the equilibrium time of scouring increases considerably. to re...

Background Research has shown that up to 33% of pressure ulcers (PUs) acquired in hospitals result from the application of a medical device. Cervical collars (C-collars) have been implicated in causing PUs, due to the mechanical force they apply to the skin. In order to improve our understanding of collar-related PUs, the present study aimed to assess the biomechanical, biochemical, and microcl...
