Data Collection III

Data Collection III

The physical assessment examines the patient for objective data that defines the patient's condition, and aids in formulating the nursing care plan. The purpose of physical assessment is a health status appraisal, which includes identifying health problems, and establishing a database for nursing intervention.
The principles to begin the physical assessment include conducting a comprehensive or problem-related history in a quiet, well-lit room, emphasizing privacy and comfort for the patient.

Area of Science:

Neuroscience and Aviation Psychology
Computational Intelligence in Human Factors

Background:

Situational Awareness (SA) is critical for safe aviation decision-making, involving perception, comprehension, and projection.
Accurate SA evaluation is vital to reduce errors in complex aviation monitoring.

Purpose of the Study:

To comparatively analyze electroencephalogram (EEG) signals and brain electrical activity mapping (BEAM) images for automated SA assessment.
To leverage machine learning and deep learning for precise SA evaluation across its three levels.

Main Methods:

Utilized EEG signals and BEAM images as physiological records for SA assessment.
Applied conventional machine learning and advanced deep learning techniques for analysis.
Benchmarked performance across different SA levels and modalities.

Main Results:

BEAM-based deep learning models achieved state-of-the-art performance (0.955) for SA perception and comprehension.
EEG signals with manual feature extraction yielded superior accuracy (0.929) for SA projection.
Demonstrated differential effectiveness of modalities across SA levels.

Conclusions:

Physiological records, particularly BEAM and EEG, show significant potential for computational SA evaluation.
Diverse physiological data can enhance aviation decision-making safety.
Future research can explore these modalities for improved human performance monitoring in aviation.
