Bennie Botha brings another element of teaching to the classroom for future healthcare professionals. Here, he facilitates a session with students from the School of Nursing.

These days we are surrounded by technology. Interactive whiteboards, 3-D printers, smartphones, laptops, e-books, and virtual reality (VR).

VR was previously associated with the gaming industry, but today it has many uses, including the healthcare industry and more specifically, the field of nursing. 

A staff member in the School of Nursing at the University of the Free State (UFS), Bennie Botha, explains that he always had a fascination with VR. With VR being more affordable to the general user and with him working in the School of Nursing, he wanted to make a difference by providing a more financially sustainable way for students to integrate theory and practical work. 

It was then that Botha, in collaboration with staff from the Department of Computer Science and Informatics and the School of Nursing, developed a virtual environment to train Nursing students as part of his master’s thesis. The title of his dissertation is: Measuring the usability and user experience of virtual reality as a teaching and learning method for nursing students. His supervisor, Dr Lizette de Wet of the Department of Computer Science and Informatics, said the cooperation between two disciplines is important. “This research can make a big contribution towards teaching and learning,” she said. 
 
Adding to existing technology-rich environment

This simulation in a computer-generated environment adds another element to teaching. Instead of only listening to a lecturer, students are immersed in a relevant teaching scenario and are able to interact within a 3D medical institution, treating and taking care of 3D patients. 

The UFS School of Nursing has implemented this first for South Africa, using VR as an instrument to train nursing students. Currently, third-year students and postgraduate Paediatrics students are exposed to this way of training.

This new invention for the School of Nursing adds to the already existing technology-rich environment of the Clinical Simulation Unit within the school; a facility where healthcare students are exposed to training in a safe environment without harming the patient, using high-fidelity patient manikins.

Cost-effective simulation platform

According to Botha, VR provides a cost-effective simulation platform that can be used to augment high-fidelity simulations. “It is also a low-cost alternative for institutions that do not have the capital to implement high-fidelity simulations. By implementing new innovative teaching methods, we aim to provide quality healthcare professionals who can showcase the educational excellence of the School of Nursing at the UFS,” says Botha.

He explains the process: “Virtual reality provides students with an opportunity to learn by engaging in a simulator-based game. The virtual environment requires the students to perform a respiratory foreign-body object simulation scenario. Before each virtual simulation session, students are briefed and given the relevant outcomes of the scenario. Students also receive a quick tutorial on the use of the controllers and the head-mounted display.”

“Once a session is complete, a debriefing session is held where students can reflect on the outcome of the simulation. They can view a recording of their own actions for self-reflection afterwards.”

Botha believes the VR environment he created for Nursing students contributes to the Fourth Industrial Revolution, giving the UFS a competitive edge in new developments and the use of innovative teaching and learning technology.

Scientists discover a water reservoir beneath the Free State
2009-12-09

Dr Holger Sommer

The Mantle Research Group Bloemfontein (MRGB), under the leadership of Dr Holger Sommer, a senior lecturer in the Department of Geology at the University of the Free State (UFS), has discovered an enormous water reservoir 160 km beneath the Free State.

This discovery, according to Dr Sommer, is the first of its kind in South Africa after he had previously made a similar finding in Colorado, USA.

However, this water cannot be used for human consumption. “It is not frozen water; it is not molecular water; it is not fresh water; it is not salty water; it is OH – water which is sitting in the crystal lattice,” he said.

He said the reservoir was comparable in size to Lake Victoria in Tanzania.
The researchers collected eclogites from the Roberts Victor (Rovic) Mine close to the town of Boshof, south-west of the Free State, for their study.

“The Rovic eclogites are rocks which represent former oceanic crust transported into the earth’s interior by complex plate tectonic processes about 2.0 billion years ago,” explained Dr Sommer.

“These rocks were finally carried back to the earth’s surface by volcanic (kimberlite) eruptions around 130 million years ago. Eclogitic rocks are therefore a window into the Earth’s interior.”

The question from the beginning for all MRGB scientists was: Is there water inside these rocks in such depth, and if so, where is it located?

To answer this question, Dr Sommer and his research fellows separated single mineral grains from eclogite samples and prepared about 100 micrometer (0,1 mm) thick rock sections. Afterwards, specific particle accelerator (Synchrotron) measurements were carried out in the city of Karlsruhe in Germany.

“And indeed, the MRGB found water inside the studied rocks from the Roberts Victor Mine,” he said. “The water was located in defect structures in crystal lattices and along boundaries between single mineral grains.”

“The occurrence of water at such depth would give first evidence that all water of the oceans could be stored five to ten times in the earth’s mantle.”
The study was conducted about a year ago.
