Nose and Nasal Cavity01:24

Nose and Nasal Cavity

11.7K
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...

Administering Oxygen by Nasal Cannula

3.1K
Oxygen therapy is critical to patient care, especially for those struggling with respiratory issues. This intervention increases the oxygen concentration in the lungs, enhancing the amount of oxygen transported to the body's tissues. One standard method of delivering supplemental oxygen is through a nasal cannula, a non-invasive device that provides low to medium oxygen concentrations.
Nasal Cannulas
A nasal cannula is a lightweight tube split into two prongs placed in the nostrils,...

Avoidance Learning and Learned Helplessness

2.6K
Avoidance learning and learned helplessness are critical concepts in understanding behavioral responses to negative stimuli.
Avoidance learning occurs when an organism learns that a specific behavior can prevent an unpleasant outcome. For example, a student who receives a bad grade may start studying harder to avoid future poor grades. This behavior persists even when the negative outcome is no longer present. Avoidance learning is powerful because it maintains behavior in the absence of the...

Associative Learning01:27

Associative Learning

1.3K
Associative learning is a fundamental concept in behavioral psychology, wherein a connection is established between two stimuli or events, leading to a learned response. This process is critical in understanding how behaviors are acquired and modified. Conditioning, the mechanism through which associations are formed, can be divided into two main types: classical conditioning and operant conditioning, each elucidating different aspects of associative learning.
Classical conditioning, also known...

Purposive Learning

503
E. C. Tolman emphasized the purposiveness of behavior — the idea that much of our behavior is goal-directed. For instance, employees who aim for a promotion work diligently to meet their targets. Tolman argued that when classical conditioning and operant conditioning occur, the organism acquires certain expectations. In classical conditioning, a child might fear a dog because they expect it to bite. In operant conditioning, a person might consistently work overtime because they expect a...

Observational Learning01:12

Observational Learning

969
Albert Bandura's observational learning, also known as imitation or modeling, occurs when a person observes and imitates another's behavior. It is a quicker process than operant conditioning. A well-known example is the Bobo doll study, where children who saw an adult acting aggressively towards the doll were more likely to act aggressively when left alone, compared to those who observed a nonaggressive adult. Many psychologists view observational learning as a form of latent learning...

Area of Science:

  • Rhinology
  • Allergology
  • Medical Imaging
  • Artificial Intelligence

Background:

  • Nasal cytology has become fundamental in rhinology over the past two decades.
  • Its simplicity and low invasiveness make it a practical diagnostic tool for rhino-allergology.
  • The method aids in defining new nosological entities and updating rhinitis classifications.

Purpose of the Study:

  • To develop a software support system using deep learning for automated nasal cytology analysis.
  • To assist rhino-cytologists by automatically identifying and classifying cells in digital nasal preparations.
  • To provide diagnostic support and improve the efficiency of nasal cytology reporting.

Main Methods:

  • Utilized image processing and segmentation techniques to identify cellular elements.
  • Developed a convolutional neural network for cell classification into seven cytotypes.
  • Integrated deep learning with digital microscopy for automated analysis of cytological preparations.

Main Results:

  • Cell identification (image segmentation) achieved a sensitivity greater than 97%.
  • Cell classification accuracy reached approximately 99% on the test set and 94% on the validation set.
  • The system demonstrated high accuracy in classifying various nasal cytotypes.

Conclusions:

  • The developed system provides valuable diagnostic support for rhino-cytologists.
  • It automates cell classification, reducing specialist workload and improving efficiency.
