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.

UFS presents sport concussion programme for schools
2008-11-14

The Sports Medicine Clinic at the University of the Free State (UFS) will present a sports concussion programme for schools in the Free State.

“The Pharos Schools Concussion Programme makes the latest methods and technology in concussion management available to learners who play contact sport,” says Dr Louis Holtzhausen, Programme Director of Sports Medicine at the UFS.

The great risk of concussion is that there is an uncertainty about when a player can return to a sport with safety and with the minimum complications in the brain. This programme fills that gap to a large extent.

“By using this programme, no player who suffers concussion will return to play before it is medically safe to do so. The programme also educates players, parents, coaches and the medical fraternity on how to manage sports concussion,” says Dr Holtzhausen.

The programme has been designed for hockey, soccer, cricket, rugby and other contact and collision sports.

SA Rugby has used the programme for professional players for the last five years and advocates that all school rugby players should participate in the programme.

Several sports teams from schools in and around Bloemfontein as well as the University’s Shimla and Irawa rugby teams have already been tested. This will provide invaluable information in the management of possible head injuries.

“We can now give definite guidelines to players and coaches regarding the safe return of players to teams after such an injury. It takes a lot of the guesswork out of the management of concussion and provides peace of mind to coaches, parents and players regarding serious injuries,” says Dr Holtzhausen.

By enrolling in the concussion programme, learners and their parents are ensured of among others:

A baseline computer brain-function test before the start of the season.
Information on how to recognise and treat concussion, including a fieldside information card for the player’s team.
A free consultation and neurological examination by a sports physician after any suspected concussion.
As many brain-function tests and sports-physician consultations as necessary after any concussion, until complete recovery.
Referral to a network of specialists if necessary.

The Pharos Programme uses a cognitive function evaluation called Cogsport. This is a neurophysiological test that measures brain function before the season starts. In this way, a baseline standard is established and, should concussion occur during the season, the extent of it can be measured according to the baseline and rehabilitation.

“Once we have the baseline values, the concussed player’s return to those levels must be monitored. He/she can return to light exercise in the meantime and semi- and full-contact can be introduced at appropriate times,” says Dr Holtzhausen.

The cost of enrolment is R200 per learner, regardless of the number of concussions suffered or sports physician consultations received. “By enrolling in this programme, parents will ensure that their child has the best chance of avoiding the potentially serious consequences of concussion, including learning disabilities, recurrent concussions, epileptic fits and even death,” says Dr Holtzhausen.

More information on the programme can be obtained from Ms Arina Otto at 051 401 2530.
