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.

Early diagnosis of hearing loss is important

One of the most common, misunderstood and neglected birth defects in developing countries is hearing loss, which can most severely impair and have a dramatic impact of the quality of life the of the person with hearing loss. 

This is according to Dr Magteld Smith, lecturer in the Department of Otorhinolaryngology at the University of the Free State (UFS). 

“Hearing loss refers to all the different types and levels of hearing loss, from slight to profound hearing loss,” she said. 

Derived from a number of retrospective studies in South Africa, it was found 17 people a day are born with hearing loss. More than 95% of those children are born to hearing parents. This estimate excludes children and adults who lost their hearing after birth. 

According to Dr Smith, hearing loss strikes at the very essence of being human, because it hinders communication with others. To enable people to communicate with those with hearing loss, the university’s Department of South African Sign Language teaches students sign language. This year, the department enrolled 230 students. A number of these students are from the Faculty of Education. These students could from 2017 for the first time choose sign language as a subject.

“Studies have shown that important language skills are learned before the age of three because hearing and learning language are closely tied together. Brain development of the auditory pathways and language cortex is occurring in young children as they respond to auditory and visual language. In families that are part of deaf culture, these parents automatically sign from day one, so the baby is learning visual (sign) language, and the appropriate brain development is occurring.

Sign Language, at the UFS. As an assignment some of the students

“However, if a child has an undiagnosed hearing loss and the parents are unaware, the child will not receive the needed language stimulation — and the hoped-for development won’t take place. It is critical to understand that children with hearing loss have their own talents, different levels of intelligence, socioeconomic circumstances and different abilities, just like hearing children. Therefore, one size does not fit all,” Dr Smith said.
