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.

Producers to save thousands with routine marketing strategies, says UFS researcher

Using derivative markets as a marketing strategy can be complicated for farmers. The producers tend to use high risk strategies which include the selling of the crop on the cash market after harvest; whilst the high market risks require innovative strategies including the use of futures and options as traded on the South African Futures Exchange (SAFEX).

Using these innovative strategies are mostly due to a lack of interest and knowledge of the market. The purpose of the research conducted by Dr Dirk Strydom and Manfred Venter from the Department of Agricultural Economics at the University of the Free State (UFS) is to examine whether the adoption of a basic routine strategy is better than adopting no strategy at all.

The research illustrates that by using a Stochastic Efficiency with Respect to a Function (SERF) and Cumulative Distribution Function (CDF) that the use of five basic routine marketing strategies can be more rewarding. These basic strategies are:
• Put (plant time)
• Twelve-segment pricing
• Three-segment pricing
• Put (pollination)(Critical Moment in production/marketing process), and
• Pricing during pollination phase.

These strategies can be adopted by farmers without an in-depth understanding of the market and market-signals. Farmers can save as much as R1.6 million per year on a 2000ha farm with an average yield.

The results obtained from the research illustrate that each strategy is different for each crop. Very important is that the hedging strategies are better than no hedging strategy at all.

This research can also be applicable to the procurement side of the supply chain.

Maize milling firms use complex procurement strategies to procure their raw materials, or sometimes no strategy at all. In this research, basic routine price hedging strategies were analysed as part of the procurement of white maize over a ten-year period ranging from 2002–2012. Part of the pricing strategies used to procure white maize over the period of ten years were a call and min/max strategy. These strategies were compared to the baseline spot market. The data was obtained from the Johannesburg Stock Exchange’s Agricultural Products Division better known as SAFEX.

The results obtained from the research prove that by using basic routine price-hedging strategies to procure white maize, it is more beneficial to do so than by procuring from the spot market (a difference of more than R100 mil).

Thus, it can be concluded that it is not always necessary to use a complex method of sourcing white maize through SAFEX, to be efficient. By implementing a basic routine price hedging strategy year on year it can be better than procuring from the spot market.
