Factors Affecting Workability

Factors Affecting Workability

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...

Work

Work

Work is a fundamental concept of mechanical engineering and has many applications. Understanding how work is calculated and the different types of work can help us better understand physical processes and provide insights into complex problems.
Work is defined as the result of a force acting on an object, causing it to move along the line of action of force. It is also defined as the process of transferring energy through the application of force on an object, resulting in its displacement.

Factors Affecting Illness

Factors Affecting Illness

When a person's physical, emotional, intellectual, social development or spiritual functioning is compromised, this deviation from a healthy normal state is called illness. Illness creates stress that in turn harms individuals. Irritation, anger, denial, hopelessness, and fear are behavioral and emotional changes an individual experiences in the phases of illness. A variety of factors influence a person's health and well-being.
For instance, risk factors are connected to illness, disability,...

Dimensions of Health and Illness

Dimensions of Health and Illness

The factors influencing the health-illness continuum can be internal or external and may or may not be under conscious control. They are related to the following eight human dimensions, and each dimension is interrelated to one other.

Area of Science:

Occupational health
Gerontology
Sociology of work

Background:

Prolonging working life necessitates maintaining workers' capacity to handle physical and psychosocial job demands.
Assessing factors influencing work ability is vital for worker retention and well-being.

Purpose of the Study:

To analyze how work-related factors and individual characteristics impact work ability.
To determine the predictive value of work ability for receiving a work-related disability pension.

Main Methods:

A longitudinal study of 850 construction workers (aged 40+) over 23 months.
Work ability was measured using the Work Ability Index (WAI).
Regression analyses (linear and Cox) assessed associations and predictive values for disability (receiving a pension).

Main Results:

Work-related factors correlated with lower baseline work ability but had limited predictive power for future disability.
Moderate and poor work ability at baseline showed high hazard ratios (8 and 32, respectively) for disability.
All WAI scales predicted future disability, with job demands and current work ability being most influential.

Conclusions:

Poor or moderate work ability strongly predicts disability pension receipt.
Preventive strategies should focus on balancing work performance and health to maintain labor participation.
