Prof Loyisa Jita
Member of sixth Umalusi Council, Prof Loyiso Jita


Umalusi council members are appointed by the Minister of Education for their professional expertise in education and training. The council is formally mandated to research matters related to the sub-framework of qualifications responsible for the General and Further Education and Training qualifications. Prof Jita will be playing a governance role in Umalusi as an organisation.

Appointment a recognition of contribution to quality assurance systems

Sharing his sentiments on the appointment, Prof Jita said it was an affirmation of his dedication to delivering quality education in the country. “Being on the council is further recognition of one’s contribution to the quality assurance systems of the country and an elevation of the role in decision-making. The council, for instance, provides final approval of Grade 12 national results in public and private schools.”

He previously served on one of the Umalusi sub-committees responsible for assessment and standards, also known as the Grade 12 Standardisation Committee.

The sixth council will meet for the first time in September for induction and allocating specific roles to members.
 
Prof Jita joined the UFS in 2012. In 2014, the University of the Free State (UFS), in partnership with the South African National Roads Agency, launched the SANRAL Chair in Science, Mathematics, and Technology Education on the Bloemfontein Campus, and Prof Jita was appointed as the first SANRAL Chair. In 2017, he was appointed as Dean of Education.

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.
