Ergonomics – making your space practical and comfortable

“Design is not just what it looks like and feels like. Design is how it works.” – Steve Jobs

Whether at work or at home, scientists have found a way to “comfortably” carry out tasks. According to Martie Bitzer, senior lecturer at the University of the Free State’s Department of Architecture, we all experience discomfort due to the effects of repetitive actions in a day – whether in daily tasks of necessity like washing the dishes or hours spent at work behind a desk or a countertop. “The word ‘ergonomics’ is the key to ease this discomfort!,” she said.

Martie believes that a space needs not only to look beautiful but that it must be practical as well.

“The specific dimensions of the human body should serve as the designer’s ‘measure’ for the height of your kitchen counter or the angle of your computer screen,” says Martie.

She continues: “In architecture, ergonomics is always the starting point for design. The architect envisions how the user will live in a space and designs accordingly. Ergonomics touches all aspects of a person’s life in a building – from the distance you walk in your kitchen while cooking to the impact of the height of a specific space. It is working at best when you live fluently in a space, unaware of obstacles and challenges. The human body’s capabilities and limitations are at the heart of the responsible designer’s task to improve the quality of life in a building.”

In a world where we are daily more aware of how we engage with our surroundings, good design matters!

Postdoctoral researcher, Abdon Atangana, of the Institute for Groundwater Studies at the university recently published an article online about the Lassa Haemorrhagic fever in the Natural Computing Applications Forum. In addition to the terminal transmissible sickness recognised as Ebola haemorrhagic fever, there is another strain called Lassa haemorrhagic fever.

The disease is classified under the arenaviridae virus family. The first outbreaks of the disease were observed in Nigeria, Liberia, Sierra Leone, and the Central African Republic. However, it was first described in 1969 in the town of Lassa, in Borno State, Nigeria.

The main host of the Lassa virus is the Natal Mulimammate mouse, an animal indigenous to most of Sub-Saharan Africa. The contamination in humans characteristically takes place through exposure to animal excrement through the respiratory or gastrointestinal tracts.

Mouthfuls of air containing tiny particle of infective material are understood to be the most noteworthy way of exposure. It is also possible to acquire the infection through broken skin or mucous membranes that are directly exposed to the infective material.

“The aim of my research was to propose a novel mathematical equation used to describe the spread of the illness amongst pregnant women in West Africa. To achieve this, I used my newly-proposed derivative with fractional order called beta-derivative. Since none of the commonly used integral transform could be used to derive the solution of the proposed model, I proposed a new integral transform called Atangana-Transform, and used it, together with some iterative technique, to derive the solution of the model.

“My numerical simulations show that the disease is as deadly amongst pregnant women as Ebola,” Abdon said.

Abdon’s research was submitted to one of Springer’s top-tier journals with an impact factor 1.78. The paper was accepted and published February 2015.
