Reliability and Validity01:29

Reliability and Validity

13.9K
Reliability and validity are two important considerations that must be made with any type of data collection. Reliability refers to the ability to consistently produce a given result. In the context of psychological research, this would mean that any instruments or tools used to collect data do so in consistent, reproducible ways.

Nose and Nasal Cavity01:24

Nose and Nasal Cavity

11.6K
The nose is composed of an observable exterior segment (external nose) and an internal segment within the skull known as the nasal cavity (internal nose). The external nose, visible on the face, consists of a framework of bone and hyaline cartilage enveloped in skin and muscle and lined with a mucous membrane. This structure is supported by the frontal bone, nasal bones, and maxillary bone and is supplemented by a cartilaginous framework comprising the septal nasal cartilage, lateral nasal...

Basicity of Aliphatic Amines01:21

Basicity of Aliphatic Amines

6.9K
Amines can behave as Brønsted–Lowry bases by accepting a proton from the acid to form corresponding conjugate acids. Due to a lone pair of nonbonding electrons, aliphatic amines can also act as Lewis bases by forming a covalent bond with an electrophile.
To measure the basicity of amines, two conventions are generally used. The first defines Kb as the basicity constant for the deprotonation reaction of water by the amine, as presented in Figure 1. Conventionally, lower Kb indicates higher...

Basic Operations on Signals01:22

Basic Operations on Signals

1.1K
Basic signal operations include time reversal, time scaling, time shifting, and amplitude transformations. These operations are fundamental in signal processing and analysis.
Time Reversal mirrors a continuous-time signal about the vertical axis at t=0. This is achieved by substituting t with −t. For example, if a signal x(t) is considered, the time-reversed signal is x(−t). This operation can be graphically represented, showing the mirrored signal.

Area of Science:

  • Medical Simulation
  • 3D Printing in Medicine
  • Surgical Education Technology

Background:

  • Three-dimensional (3D) printed models show promise for surgical training in rhinology.
  • Developing realistic models for endoscopic training is crucial for skill acquisition.

Purpose of the Study:

  • To develop 3D-printed models of pediatric and adult nasal cavities and postsurgical paranasal sinuses.
  • To assess the face and content validity of these 3D models for endoscopic training.

Main Methods:

  • Computed tomography (CT) data from pediatric and adult patients were used to create nasal cavity models.
  • CT data from a postsurgical patient generated the paranasal sinus model.
  • Rhinologists evaluated model fidelity and utility using Likert scales and task completion time compared to residents.

Main Results:

  • 3D models were prototyped within 24 hours at a low cost (<15 USD per model).
  • Models received high overall scores (above 4.0) for fidelity and usefulness in endoscopic training.
  • Rhinologists completed training tasks significantly faster than residents, validating the models' utility.

Conclusions:

  • Desktop 3D-printed models of nasal cavities and paranasal sinuses are high-fidelity and cost-effective.
  • These models are valuable tools for training basic endoscopic skills in rhinology.
  • The developed models demonstrate strong potential for enhancing surgical education.
