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.

Shortage of quantity surveyors discussed at UFS

Shortage of quantity surveyors discussed at UFS

 “The South African building industry is experiencing an unprecedented high level of economic growth and prosperity.  This is causing a definite shortage of registered quantity surveyors,” said Mr Egon Wortmann, Director of the Association of South African Quantity Surveyors(ASAQS) during the association’s recent visit to the Department of Quantity Surveying and Construction Management at the University of the Free State (UFS).

 “This shortage is especially noticeable in local and national governments where unqualified and inexperienced staff, consultants and/or facilitators are now appointed,” said Mr Wortmann. 

 In doing so, the authorities that have adopted this approach are according to Mr Wortmann actually acting illegally and are not in compliance with the legal and statutory requirements of South Africa.  “These unprofessional practices are unproductive, it leads to frustration and is strongly condemned by the ASAQS,” he said.

 “The service delivery of these unqualified and unregistered service providers is often sub standard and does not comply to the legal requirements of the profession.  It may also result in the tarnishing of the image and high professional standards set by the quantity surveying profession,” said Mr Wortmann.

 “Universities offering programmes in quantity-surveying and construction management are also negatively affected by the high levels of activity in the building environment.  Suitable lecturing staff are leaving the academic institutions as they are attracted to better opportunities being offered in the building industry. The ability of the tertiary institutions to attract young academics, to train them and to keep them in the longer term, is therefore almost impossible”, said Prof Basie Verster, head of the Department of Quantity Surveying and Construction Management at the UFS and representative of the Free State on the ASAQS.

 According to Prof Verster the UFS supplies more than its quota of qualified quantity surveyors to the South African building industry.  “Although more than 460 students are registered in construction related programmes at the UFS, we are as the ASAQS’s concerned about the shortage of students that can enter the construction industry.  In our case, we  are experiencing a shortage in black female students,” he said.

 “Of the 460 postgraduate students, 38% are black of which 20% are female students.  Graduates do also not necessarily stay in the country.  As the UFS’s programmes are accredited overseas, a lot of our students leave the country for working opportunities elsewhere,” said Prof Verster.

 Mr Patrick Waterson, President of the ASAQS, appealed to quantity surveyors to, when they are approached, consider academic careers or to make themselves available to lecture on a part time basis.  “I also appeal to quantity-surveying practices, construction companies and developers to consider taking part in training activities,” he said.

 The ASAQS has over the years developed a proud tradition within the quantity-surveying profession. Consequently membership of this organisation is a sought after goal for many members within the building environment. International agreements with various countries are also in place whereby it is mutually agreed that local as well as overseas qualifications are mutually acceptable on a reciprocal basis. 

 A more recent addition to the list of agreements is the reciprocity agreement entered into with the Royal Institution of Chartered Surveyors which makes it possible for South African based quantity surveyors to practice in over 120 countries worldwide.
