Flow Table Test

Flow Table Test

The flow table test is an established method used to assess the workability of concrete, particularly useful for evaluating highly flowable concrete mixes. This test employs an apparatus that consists of a wooden board topped with a steel plate, collectively weighing 35 pounds. The board is connected to a base via a hinge and measures 27.6 inches on each side.
Concrete is placed within a truncated cone mold that is 8 inches high with an 8-inch base diameter and a 5-inch top diameter. The...

Leveling Equipment

Leveling Equipment

As leveling involves measuring vertical distances relative to a horizontal line of sight, it requires a graduated rod, called a level rod, for vertical measurements and an instrument called a level for a horizontal sight line. A level includes a high-powered telescope with a mechanism for leveling to ensure the line of sight is horizontal when the bubble in the spirit level is centered. Leveling rods, made of wood, metal, or fiberglass, are graduated in feet or meters and commonly used in two-...

Area of Science:

Occupational health
Human-computer interaction
Ergonomics

Background:

Sit-stand desks promote health benefits by reducing sedentary behavior.
Accurate measurement of sit-stand desk usage is crucial for research and interventions.
Existing methods for tracking desk usage may lack accuracy or user-friendliness.

Purpose of the Study:

To develop and validate an open-source device, the Desk Positioning System (DPS), for measuring sit-stand desk usage.
To assess the accuracy, usability, and acceptability of the DPS across different conditions and desk types.

Main Methods:

The Desk Positioning System (DPS) was developed as an open-source device.
Accuracy was tested in controlled (Study 1) and free-living (Study 2) settings, with video as a criterion.
Usability and acceptability were evaluated over short-term (1 week) and longer-term (5 weeks) periods (Study 3).

Main Results:

The DPS achieved 100% accuracy in identifying desk presence and height in Study 1.
In Study 2, the DPS demonstrated high accuracy (F1>0.95) and precision (>0.98) against video recordings.
Study 3 participants reported high acceptability (4.4-4.6/5) and usability (scores above industry benchmark) for the DPS.

Conclusions:

The Desk Positioning System (DPS) offers a highly accurate method for quantifying sit-stand desk usage.
The device is both acceptable and usable for participants in short-term and longer-term studies.
The DPS presents a valuable tool for researchers and clinicians investigating sedentary behavior and workstation ergonomics.
