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.

Research into surrogate milk important to wildlife conservation

Research is being done at the University of the Free State (UFS) to analyse and synthetically imitate the unique milk of various wildlife species. This research is not only of scientific value, but also serves the conservation of South Africa’s wildlife species. At the forefront of this research is Prof Garry Osthoff from the Department of Microbial, Biochemical and Food Biotechnology.

Orphaned rhino calf pulled through with surrogate milk

“There is still a lot of research to be done. Naturally the research is of scientific importance, but with surrogate milk having the same composition as the mother’s milk of a specific species, orphaned calves or cubs of that species could be pulled through during a difficult time of weaning. Bearing in mind that exotic animals fetch thousands and even millions of rands at auctions, it goes without saying a game farmer will do everything possible to provide only the best nourishment to such an orphaned animal. In such a case, synthetically-manufactured milk would be the right choice,” says Prof Osthoff.

The fruits of his research were recently demonstrated in Germany when a rhino calf was left orphaned in the Leipzig Zoo. Prof Osthoff’s article: “Milk composition of a free-ranging white rhinoceros during late lactation” was used as a directive for applying surrogate milk for horse foals (which is already commercially available), since the composition of horse and rhino milk largely corresponds. The surrogate milk was used with great success and the rhino calf is flourishing. He mentions that such an orphan is often given the wrong nourishment with the best intentions, resulting in the starvation of the animal despite the amount of cow’s milk it devours.

Milk formula for baby elephants in the pipeline
With baby elephants left orphaned due to the increase in elephant poaching for their ivory, several attempts have been made to create a milk formula in order to feed these elephants. To date, many elephants have died in captivity from side effects such as diarrhoea as a result of the surrogate formula which they were fed.

Prof Osthoff recently received a consignment of frozen milk which he, together with researchers from Zimbabwe, will use to work on a milk formula for elephants. They are studying the milk in a full lactation period of two years. During lactation, the composition of the milk changes to such an extent that a single surrogate formula will not be sufficient. Four different formulas should probably be designed.

Prof Osthoff says that of the different species he has researched, elephants are the most interesting and deviate most from the known species.

Although his research to develop surrogate milk is adding much value to the wildlife industry, and although he finds this part of his work very exciting, his research focus is on food science and nutrition. “What is currently authentic in milk research is the study of the fat globules with content, the structure and composition of the casein micelle, and the prebiotic sugars. The knowledge which is gained helps to improve the processing, development of new food products, and development of food products for health purposes,” says Prof Osthoff.
