UFS Creative Clubs

In an ever-changing, increasingly complicated world, the youth must be prepared to bring knowledge and skills to solve issues, make sense of information, and know how to acquire and analyse evidence to make judgements. Science, Technology, Engineering, and Mathematics (STEM) education encourages discussions and problem-solving among students, developing practical skills and an appreciation for collaborations. 

The Social Responsibility Projects department on the UFS South Campus is running a Creative Clubs programme that speaks to STEM education and collaboration.

Opening opportunities 

The primary goal of Creatives Clubs, a MerSETA-funded programme, is to open opportunities to develop problem-solving, critical thinking, and reasoning skills. One aspect Creative Clubs focuses on is identifying potential in the pupil and supporting them in participating in the Eskom Expo for Young Scientists. Learners participate in mathematics, science, and coding activities at the club.

According to Joleen Hamilton, the coordinator and founder of Creatives Clubs, they currently host top-achieving learners in maths from eight schools from Grades 8–12 in Bloemfontein. These schools are split into two groups, which meet at the South Campus on Tuesdays and Thursdays. “We need maths daily, since it stimulates the intellect and aids problem-solving. That’s why, no matter how complicated the sum looks, keep trying and do not give up,” Hamilton said at one of the maths sessions.

Enhancing critical thinking

Matheko Thamae, also a coordinator, mentioned that this programme significantly improves maths and science outcomes for high school learners. “With a dynamic world of innovation and the 4th Industrial Revolution (4IR), the club also assists learners with critical thinking and in solving their communities’ socio-economic issues,” Thamae said. 

“Attending these sessions assists me in thinking out of the box and realising that every problem has a solution. I will continue to attend the programme so that I can find solutions to unresolved problems,” Sechaba Ramakatsa, a Grade 9 learner from Lekhulong Secondary School, said. Ramakatsa, who enjoys assisting others, aspires to be a medical doctor so that people might have better healthcare experiences.

Three heart-valve studies which have been developed at the Robert WM Frater Cardiovascular Research Centre at the School of Medicine at the University of the Free State (UFS) were recently presented in Monte Carlo at the conference of the prestigious global Heart Valve Society (HVS).

These studies are all headed by Prof Francis Smit, Head of the Department of Cardiothoracic Surgery at the UFS, and Manager of the Robert WM Frater Cardiovascular Research Centre.
Prof Smit says the HVS is a combination of the former heart-valve societies of Europe and the US. “Studies on heart-valve disease, heart-valve-related products and operations, as well as the design and development of new valves were presented. There are both clinical and development divisions.

He says the study in which the hemodynamics of their redesigned mechanical poppet valve was compared to a commercial bi-leaflet mechanical heart valve, was named as the best poster presentation in the experimental valve development and numerical flow dynamics division. The study, which was presented by Kyle Davis, mechanical engineer at the centre, competed against some of the best heart-valve research units in the world.

The redesigned valve, based on the 1960s Cape Town poppet valve, has the potential to provide a low-cost solution for mechanical heart-valve replacement. It is possible to produce the titanium ring with 3-D printers and is, together with the silicon poppet valve, extremely inexpensive compared to current mechanical valve-manufacturing processes.
The advantages of this valve over current mechanical valves is that, due to the effective and laminar flow characteristics, as well as the simple locking mechanisms, there is a reduced chance of valve thrombosis, and the need for anti-clotting drugs is therefore limited.

It was also confirmed that the new valve more than meets the published FDA (Federal Drug Agency) requirements, which determine the minimum standards of valves for human use in the US.

The redesigned valve also has a very low platelet activation impact, which is responsible for platelet thrombosis and leads to valve thrombosis or strokes. This valve is another heart-valve project by the centre, which is also in the process of evaluating a tri-leaflet polyurethane valve developed by them.
