Dr Ocaya
Dr Richard Ocaya’s research addresses the skills development and transfer millennium goal of many governments globally.

With the Fourth Industrial Revolution becoming a reality, Dr Richard Ocaya’s research is receptive to the fact that Africa and the world need to re-imagine their research. His research focuses on electronic instrumentation design for scientific measurements, computational physics on atomic nano-atomic structures, and semiconducting organic compounds materials built on silicon to realise Schottky devices.

Software developer 
“I develop most of the instrumentation that I apply in my research – both software and hardware,” said Dr Ocaya, a Physics Lecturer and Programme Director: Physics and Chemistry on the UFS Qwaqwa Campus.

“I am active in scientific computing through the computing cluster and software development, mathematical physics for material science modelling, and embedded instrumentation design using microprocessors. I also have deep interest in radio and data telemetry, in which I hold a South African patent issued in 2013. My present international collaborations are with like-minded researchers in similar fields in Saudi Arabia, Turkey, Japan, Egypt, South Korea, and the United States,” he added.

How does his research talk to the real world?
“The driving principle of all areas of my research has always been to deploy cutting-edge research to actual, real-world applications for the immediate betterment of Africans. The areas of my research align closely with the millennium goals of many governments globally, including the Republic of South Africa. These goals pertain to skills development and transfer that position us to better address the challenges of energy, water, and other priorities.”

Dr Ocaya is currently co-promoting a PhD student, having previously supervised one PhD, two MSc, and more than twenty honours students. He is a self-taught electronics and computer programmer, whose curiosity led him to question ‘the voices and music coming from a box; a radio’. “In my quest to satisfy my curiosity, I collected many discarded devices, took them apart, and tried so many circuits, only to have them fail because the theory was lacking. After thousands of failed projects and with me barely thirteen and in lower secondary school, my first ever project actually worked,” he said.

NRF-rating
He is the author of the book Introduction to Control Systems Analysis using Point Symmetries: An application of Lie Symmetries, which is available in all major bookstores such as Amazon, in both print and e-book format. He is a C3 NRF-rated researcher whose work makes a pioneering contribution to the new and growing field of phononics, an independent field of the now established photonics.

“This field will someday lead to improved energy-storage devices and faster processors due to more efficient heat removal from nanodevices,” he concludes.

Training in critical medical skills receives preference at the UFS
2015-07-24

The UFS bought a new simulator for surgeons to learn how to perform laparoscopic operations. During the launch of the simulator, Dr Mathys Labuschagne (left), Head of the Clinical Simulation and Skills Unit, illustrates to Prof Gert van Zyl, Dean of the faculty, how the simulator works.

The Clinical Simulation and Skills Unit in the University of the Free State (UFS) Faculty of Health Sciences purchased a new laparoscopic simulator for R1.2 million recently. The simulator will be used to teach postgraduate medical students how to perform laparoscopic surgery. The UFS is currently the only university in the country, and one of only two institutions in South Africa, that own such a simulator.

The Lapsim simulator, from Surgical Science in Sweden, is a highly sophisticated computerised tool for the training and improvement of laparoscopic surgical skills in postgraduate students within the surgical disciplines.

“The purpose of a simulator is not to replace training on patients, but to help registrars in acquiring basic laparoscopic surgical skills,” says Dr Mathys Labuschagne, Head of the Clinical Simulation and Skills Unit.

These skills include depth perception, hand-eye-coordination, instrument handling, precision and speed, which are essential before operations can be performed on patients.

Prof Gert van Zyl, Dean of the Faculty of Health Sciences, says this simulator is very important for the UFS to train registrars more effectively in theatre work.

“Not only registrars will benefit from this, but qualified surgeons may also make use of it to improve their skills.”

The simulator is pre-programmed for different medical conditions that laparoscopic surgery is traditionally used for. Programmes can be selected for procedures such as sterilisation, cholecystectomy (gall bladder removal), endometriosis, etc. The simulator even makes it possible simply to practise eye-hand coordination, and to apply stitches internally.
