Summary
The COVID-19 pandemic increased computer vision syndrome (CVS) in remote and hybrid workers. Implementing user-friendly visual ergonomics strategies can help prevent widespread CVS onset.
Area of Science:
- Occupational Health
- Ergonomics
- Ophthalmology
Background:
- The COVID-19 pandemic shifted work environments towards remote and hybrid models.
- This necessitates an investigation into visual ergonomics within these new settings.
Purpose of the Study:
- To assess computer vision symptoms (CVS) and visual ergonomics.
- Focus on the eye-to-screen relationship in remote and hybrid work during the pandemic.
Main Methods:
- A survey in September 2021 included the Computer Vision Syndrome Scale (CVSS17) and human factors/ergonomics questions.
- Sixty-six professionals (44 remote, 22 hybrid) participated.
- Cramer's V assessed correlations between variables for eye health.
Main Results:
- Computer vision syndrome symptoms were markedly higher compared to previous studies.
- Hybrid workers reported eye strain and dryness (V=0.6872, p=0.002; V=0.5912, p=0.0179).
- Remote workers bothered by light reported eye dryness (V=0.3846, p=0.0005). Remote work involved more screen hours (>9 hrs for 43%) than hybrid work (4%).
Conclusions:
- A significant increase in CVS was observed in remote and hybrid workers.
- Awareness of applied visual ergonomics and user-friendly strategies can prevent widespread CVS.
- This study highlights the need for proactive eye health management in evolving work environments.

Virtual Work
930
The principle of virtual work states that if a body is in static and dynamic equilibrium, then the sum of all the virtual work done by all external forces and couple moments for any given virtual displacement must be zero.
In static equilibrium, a body can experience an imaginary or virtual movement, such as displacement or rotation. The virtual work done by a force is equal to the dot product of force and virtual displacement in the direction of the force. When it comes to virtually rotating a...

PPE Use in Healthcare Settings I: Donning
1.1K
Donning PPE must be completed before contact with the patient. This process protects from infectious agents. The sequence and action included in each donning are critical, and the steps must be systematic to avoid exposure to pathogens. The institutional policy also needs to be followed while donning PPE. The pre-donning preparations are gathering equipment, inspecting the PPE equipment for tears, holes, or damage, removing jewelry, removing any garments below the elbows, and tying the hair...

Design Consideration
308
Designing a structure involves a series of considerations, primarily the material's ultimate strength, calculated through tests that measure changes under increased force until the material reaches its breaking point or limit. The ultimate load, where the material breaks, is divided by its original cross-sectional area, resulting in the ultimate normal stress or strength. The ultimate shearing stress is another significant factor taken into account.

Personal Protective Equipment
1.7K
Personal protective equipment (PPE) is unique clothing or equipment worn by an employee to minimize or prevent exposure to infectious agents. PPE creates a barrier between the employee and the infectious materials. PPE must be readily available in the patient care area. PPE includes gloves, gowns and aprons, masks and respirators, goggles, face shields, shoes, and headcovers:

Factors Affecting Workability
104
The workability of concrete is a critical characteristic that influences the ease of mixing, handling, and finishing the concrete. It is affected by several factors including water content, aggregate properties, and admixtures like air entrainment. Water plays a fundamental role as it lubricates the concrete mix, facilitating easier movement and placement. However, the water requirement varies depending on the texture and shape of aggregates. Finer particles and angular, rough-textured...
