Future of South Africa discussed at UFS peace conference
Delegates form the UFS and Osaka University gathered together at the Peace Conference.

The Department of Political Studies and Governance as well as the Centre for Africa Studies at the University of the Free State (UFS), together with the Osaka School of International Public Policy of Osaka University, jointly hosted a Quo Vadis South Africa Conference at the UFS on 12 and 13 February 2018.

Prof Hussein Solomon, Department of Political Studies and Governance, stated: “The focus is very much policy-oriented using academic insights to help resolve the myriad challenges confronting South Africa as a country as well as those on the continent.”

Prof Philippe Burger, Head of the Department of Economics and Acting Dean at the Faculty of Economic and Management Sciences at the UFS, spoke on the state of the national economy saying that factors contiguous to education could explain unemployment in South Africa. He pointed out that 60% of the population who were unemployed had not completed high school. He said only 20% of the employed population had tertiary education. Prof Burger said that labour-intensive, export-driven and investment-driven growth are the three integral sectors to consider when looking to improve the economy and overall growth of the country.

Prof Andre Duvenhage from North-West University delivered a presentation on his Strategic Perspectives of the ANC’s 2017 National Conference. Prof Duvenhage said that he had anticipated President Jacob Zuma’s recent departure from the ANC, saying his exit strategy had been negotiated behind the scenes. Some of his focal points included the state decay as a result of corrupt state practices, and the ideal future of the legitimate state which envisions the optimistic turn-around of the current condition of the South African Constitution.

“The future of Africa will be determined by politics”, said Jakkie Cilliers; Chairperson of the board, and Head of African futures and Innovation at the Institute for Security Studies. He explained that politics would drive events leading up to the national elective conference. This would offer political-election-outcome forecasts for 2019, 2024 and 2029 for the ANC, DA, EFF, and other national political parties.

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.
