Summary
The free-address office system improves workspace and communication but may lead to poor posture and pain for visual display terminal (VDT) workers. Further research is needed to understand health impacts.
Area of Science:
- Occupational Health
- Ergonomics
- Office Design
Background:
- The free-address system, a novel office layout, allows workers to choose their workspace.
- Its impact on visual display terminal (VDT) workers' posture and workload is not well understood.
Purpose of the Study:
- To investigate the effects of the free-address system on VDT workers' posture and workload.
- To compare the free-address system with the traditional fixed-address layout.
Main Methods:
- A questionnaire survey was conducted among 203 male system engineers (aged 20-59) using notebook computers.
- Participants were divided into two groups: 150 using the free-address layout and 53 using the fixed-address layout.
Main Results:
- The free-address layout enhanced individual workspace and worker satisfaction with communication and support.
- However, workers in the free-address system adopted unsuitable postures, often without adjusting chair height.
- This layout may increase the risk of neck/shoulder and low back stiffness or pain.
Conclusions:
- While offering workspace benefits, the free-address system presents potential health risks for VDT workers.
- Further investigation into the long-term effects on VDT worker health is crucial.

01:06Virtual Work for a System of Connected Rigid Bodies
Virtual work is a powerful method used to solve problems involving several connected rigid bodies. When the system is in equilibrium, virtual work is zero. This allows the calculation of the resulting forces when a system undergoes a virtual displacement. When attempting to analyze such a system, first, use a free-body diagram, where an independent coordinate represents the configuration of the links, and mark its deflected position resulting from the positive virtual displacement.

01:20Virtual Work
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...

02:30Quantifying Work
As a system undergoes a change, its internal energy can change, and energy can be transferred from the system to the surroundings, or from the surroundings to the system.
01:17Work Done During Volume Change
In mechanics, work is done on an object when the force acting on it displaces the object. In thermodynamics, work done on a system can be estimated when the system's volume changes during any thermodynamic process.
Consider a gas confined to a cylinder fitted with a movable piston at one end. If the gas expands from volume V1 to volume V2, it exerts a force on the piston, such that the piston moves by a distance dr.
The work done by the gas on the piston can be expressed as

01:13Principle of Virtual Work: Problem Solving
The principle of virtual work is an essential concept in the field of mechanics and engineering. This is used to solve problems related to the equilibrium of a structure or system. It is based on the assumption that if a system is in equilibrium, the work done by all the forces during a virtual displacement is zero. This principle is applied by considering virtual displacements of the system and the corresponding work done by internal and external forces.

01:10Work and Energy for Variable Forces
When an object is acted upon by a variable force, the amount of work done and the change in energy of the object can be more complex to calculate compared to when a constant force is applied. Work is the product of force and displacement, while energy is the capacity of a system to do work. When a constant force is applied to an object, the work done can be calculated as the product of the force and the distance moved in the direction of the force. However, when a variable force is applied, the...
