Dr Rouxan Fouche — Dr Rouxan Fouché on stage in the Callie Human Centre during his graduation ceremony. He hopes his PhD findings will be used to improve the UFS’s Information Technology Service-Learning (ITSL) project’s effectiveness.

When Dr Rouxan Fouché decided to undertake a PhD in Computer Science and Informatics, he was motivated by his commitment to addressing the digital divide in South Africa through service-learning. Through his research, he investigated how the UFS’s Information Technology Service-Learning (ITSL) project could be improved by collaboration with all project stakeholders to positively address and impact the digital divide in the local Mangaung community.

Dr Fouché is a lecturer in the Department of Computer Science and Informatics at the University of the Free State (UFS) and received his PhD during the UFS’s April 2023 graduation ceremonies.

He based his PhD thesis, titled ‘Addressing the South African Digital Divide through a community-informed strategy for Service-Learning: A Critical Utopian Action Research (CUAR) Approach’, on the service-learning module he taught after he realised the positive effect of an information technology-focussed service-learning module on computer literacy levels in the local community. “The initial goal of the service-learning module was to provide free computer literacy training to computer-illiterate community members as part of the students’ community engagement,” Dr Fouché said.

Community-focused PhD research

According to Dr Fouché researchers have recently started looking at how universities can use their service-learning modules (as part of community engagement) to bridge and address the digital divide. He also believes “current conceptualisations indicate that most university service-learning endeavours are organised without engaging with the local community or incorporating their specific needs.”

This is where he hopes his research and findings could make a difference.

His study aimed to re-evaluate and revise the ITSL project by using a hands-on, collaborative approach which included all ITSL project stakeholders. Members of the community served by the project were involved in the shared decision-making and knowledge sharing. “Furthermore, the short-term and lasting impacts of this revised community needs-led ITSL project on the participating community members were investigated.”

The study was conducted in three cycles: Cycle 1 constituted a survey approach to identify the concerns and possible shortcomings of the ITSL project. In Cycle 2, all stakeholders participated in a ‘Future-Creating Workshop’, which reviewed findings from Cycle 1, and a utopian action plan was developed by all involved. Cycle 3 saw the revised project being implemented based on all the recommendations from the previous cycle. “This cycle also included the evaluation of the project’s immediate impact using pre-test and post-test questionnaires completed by project participants.”

Service-learning project made a difference

When Dr Fouché initiated the ITSL project in 2015, the main objective was to serve and equip Mangaung and surrounding communities with necessary computer literacy skills. The programme entails training in Microsoft Word and Excel via two short learning programmes.

The impact of the programme was far-reaching, as it enabled participants to gain formal employment. “The participants told me that they were able to find employment as service station attendants, administrative clerks, and cashiers, among other roles, due to the computer literacy certificates they received after completing the ITSL project.” Witnessing the positive impact of the ITSL programme led Dr Fouché to focus his PhD research on improving the service-learning offerings the UFS provides for the community.

“I realised that it was necessary to investigate how the ITSL project could be improved and tailor-made for the community it serves,” he said.

Nanotechnology breakthrough at UFS

2010-08-19

Ph.D students, Chantel Swart and Ntsoaki Leeuw

Scientists at the University of the Free State (UFS) made an important breakthrough in the use of nanotechnology in medical and biological research. The UFS team’s research has been accepted for publication by the internationally accredited Canadian Journal of Microbiology.

The UFS study dissected yeast cells exposed to over-used cooking oil by peeling microscopically thin layers off the yeast cells through the use of nanotechnology.

The yeast cells were enlarged thousands of times to study what was going on inside the cells, whilst at the same time establishing the chemical elements the cells are composed of. This was done by making microscopically small surgical incisions into the cell walls.

This groundbreaking research opens up a host of new uses for nanotechnology, as it was the first study ever in which biological cells were surgically manipulated and at the same time elemental analysis performed through nanotechnology. According to Prof. Lodewyk Kock, head of the Division Lipid Biotechnology at the UFS, the study has far reaching implications for biological and medical research.

The research was the result of collaboration between the Department of Microbial, Biochemical and Food Biotechnology, the Department of Physics (under the leadership of Prof. Hendrik Swart) and the Centre for Microscopy (under the leadership of Prof.Pieter van Wyk).

Two Ph.D. students, Chantel Swart and Ntsoaki Leeuw, overseen by professors Kock and Van Wyk, managed to successfully prepare yeast that was exposed to over-used cooking oil (used for deep frying of food) for this first ever method of nanotechnological research.

According to Prof. Kock, a single yeast cell is approximately 5 micrometres long. “A micrometre is one millionth of a metre – in laymen’s terms, even less than the diameter of a single hair – and completely invisible to the human eye.”

Through the use of nanotechnology, the chemical composition of the surface of the yeast cells could be established by making a surgical incision into the surface. The cells could be peeled off in layers of approximately three (3) nanometres at a time to establish the effect of the oil on the yeast cell’s composition. A nanometre is one thousandth of a micrometre.

Each cell was enlarged by between 40 000 and 50 000 times. This was done by using the Department of Physics’ PHI700 Scanning Auger Nanoprobe linked to a Scanning Electron Microscope and Argon-etching. Under the guidance of Prof. Swart, Mss. Swart en Leeuw could dissect the surfaces of yeast cells exposed to over-used cooking oil.

The study noted wart like outgrowths - some only a few nanometres in diameter – on the cell surfaces. Research concluded that these outgrowths were caused by the oil. The exposure to the oil also drastically hampered the growth of the yeast cells. (See figure 1)

Researchers worldwide have warned about the over-usage of cooking oil for deep frying of food, as it can be linked to the cause of diseases like cancer. The over-usage of cooking oil in the preparation of food is therefore strictly regulated by laws worldwide.

The UFS-research doesn’t only show that over-used cooking oil is harmful to micro-organisms like yeast, but also suggests how nanotechnology can be used in biological and medical research on, amongst others, cancer cells.

Figure 1. Yeast cells exposed to over-used cooking oil. Wart like protuberances/ outgrowths (WP) is clearly visible on the surfaces of the elongated yeast cells. With the use of nanotechnology, it is possible to peel off the warts – some with a diameter of only a few nanometres – in layers only a few nanometres thick. At the same time, the 3D-structure of the warts as well as its chemical composition can be established.
