Social Work students at the UFS are working with the relevant stakeholders in an Engaged Teaching and Learning service-learning project to promote and respect children’s rights.

The protection of children’s rights is the principal achievement on the Sustainable Development Goals (SDGs) 2030 Agenda. Emphasis has always been on the promotion and respect of children’s rights. Since the SDGs are grounded in a child rights-based approach, the University of the Free State (UFS) Social Work students – by engaging in a multi-disciplinary methodology – involve all the relevant stakeholders in their Engaged Teaching and Learning service-learning module project. 

The social partners, which included the South African Police Service (Child Protection Unit), the Department of Social Development, the Department of Home Affairs, the Department of Health, faith-based organisations, and other children’s advocacy agents, were involved from inception until the apex launch of the project. 

Access to basic human rights

In their exit level, fourth-year Social Work students participate in community work practicums, which incorporates the theoretical development process in adherence to the objectives of their community work. The initial phase of the project involved the situation analysis exercise, which the students implemented through collaboration with the Rekgonne Primary School action committee. 

The outcome of the survey indicated that some learners were exposed to physical and sexual abuse. It was also found that they did not have access to basic human rights such as education, health care, and social grants due to the absence of the required legal documents. From the interactive discussions that took place during the launch, it emerged that some children do not have birth certificates required for school registration and access to social grants. 

Through the students’ community project, a platform was created where important skills and information could be shared among all important role players (who are in different professions and guardians of children’s human rights). It is believed that since learners are spending more hours in school, educators would be the primary detectors to notice signs of negligence and potentially adverse circumstances among their learners.

Role players collaborate to make a difference

Through the scholarship of engagement, students succeeded in engaging with the community to attend to societal challenges (violated children’s rights). In order to realise the outcome of the project, continuous collaboration among all role players must be sustained. All parties adopted a resolution to create safe environments both at school and at home by supporting families and caregivers.

Government partners that participated were determined to strengthen protection systems and improve child welfare, reinforcing the implementation of the Children’s Act 38 of 2005.  Educators were empowered and supported in the mandate of the Quality Learning and Teaching Campaign (QLTC). This is an initiative that involves stakeholders in improving the quality of education for all children and addresses issues of safety and well-being for all children.

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.

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.
