[Use of the uncontrolled experiment principle in evaluating and predicting of the effect of occupational factors on stress of operator work]

Area of Science:

• Occupational Health
• Ergonomics
• Industrial Hygiene

Context:

• Study conducted under uncontrolled industrial conditions.
• Operators spend 80-90% of their time at the workplace exposed to occupational factors.
• Physiological data collected considering exposure time and changes in physiological parameters.

Purpose:

• To identify main occupational factors influencing operator health status.
• To quantify the percentage contribution of each factor to overall dispersion.
• To develop a regression equation for evaluating and forecasting operator strain.

Summary:

• Utilized a passive experimental design with discrete registration of occupational factors and physiological responses.
• Data divided into pre- and post-dinner break patterns to account for work capacity fluctuations.
• Manifold correlation analysis identified key occupational health determinants and their impact.

Impact:

• Provides a method to evaluate and forecast operator strain.
• Contributes to understanding occupational factors affecting health status in industrial settings.
• Enables proactive health management strategies for operators.
