A data scientist and research coordinator at the University of the Free State (UFS), in collaboration with his supervisor at the University of Pretoria (UP), is at the forefront of the fight against the Covid-19 virus with accurate data and analysis.
Herkulaas Combrink of the Centre for Teaching and Learning at the UFS and PhD candidate in Computer Science at the UP, said accurate data is important to prevent widespread panic and sensationalism during a global disaster such as the current pandemic. This information helps people to make informed decisions and to reduce their exposure to the threat of the virus.

Assisting decision-makers

“I, along with colleagues from the World Health Organization, the Centers for Disease Control and Prevention in the USA, the provincial office of the Centers for Disease Control and Prevention, provincial clinicians, and the Free State Department of Health led by Dr David Motau, have been able to progress significantly in terms of evidence-based tools to assist provincial and national decision-makers during these turbulent times.”
“It does come at a cost, though, in that we have worked continuously since the lockdown, dedicating all our time and efforts to the department from all over to ensure that we are not part of some of the global statistics we have seen,” said Combrink. 

A paper written together with his supervisor, Dr Vukosi Marivate, has also been accepted by the Department of Higher Education and Training (DHET)-accredited Data Science Journal.  This paper is related to a framework for sharing public data to the public in a way that is useful, usable, and understandable. 

Ongoing projects

Combrink said it is hard to name all those who are/were involved in the great work done by the Free State Department of Health, but some of them include Dr Elizabeth Reji (Head of Department, Family Medicine), Dr Collin Noel (surgeon, senior lecturer at the UFS), Dr Sammy Mokoena (community health registrar, UFS), Dr Ming-Han Motloung (public health medicine specialist, senior lecturer, UFS), Dr Perpetual Chikobvu (Director: Information Management at the Department of Health, affiliated lecturer at the UFS), as well as Alfred Deacon (lecturer at the UFS), who have worked at some point during this short space of time on one of the many projects. 

Some of the projects include the following:

• A provincial database for screening and monitoring.
• A data pipeline and assembly of hospital information flow, liaised with the NICD, Vodacom, and the different district managers to ensure that the pipeline occurs in a timely manner.
• Digitised paper-based capturing tools for rapid data capturing and processing.
• Incorporated state-of-the-art visualisation tools to action data into useful information for decision-makers in certain areas.
• Provided both provincial and national projections, stress testing different scenarios using a variety of statistical, computational, and/or machine-learning approaches to add to the already existing projections of the Council for Scientific and Industrial Research (CSIR).
• Training healthcare professionals in the field to apply these tools within their own districts.
No easy task

“These aforementioned feats were by no means easy and are not completed yet, but we are getting there. In the foreseeable future, I will be working closely with national and international researchers to deploy a tool for hospital managers in the Free State that will assist them when we move from level 5 to any level below.”

“In addition to this, I am constantly providing support to the Free State Department of Health regarding any analysis required for decision-making purposes. The teams we work in comprise highly competent individuals with a passion for solving problems from multidisciplinary perspectives,” according to Combrink.

“The learners of the High School Witteberg are a wonderful example of the quality of students that we can expect as first years here at Kovsies next year,” Prof. Jonathan Jansen, Rector and Vice-Chancellor of the University of the Free State (UFS) said last night during a matric evening attended by 121 Grade 12 learners and their parents in a packed hall at the Secondary School Witteberg in Bethlehem.

Prof. Jansen and his wife Grace, as well as some of his colleagues were guests of honour at the event.

“We want to make a difference in the lives of our students at Kovsies and we want to ensure that our students make a difference in a divided world. This is why I want each Grade 12 learner who is here tonight to come and study at the UFS,” he told the learners and their parents.

“The UFS is going to become the university in the country that is serious about quality. We want to draw the best students. Quality entails hard work. It is about perseverance and your commitment towards your studies. That is the type of students we want.”

“My door is open to our students and they have access to come and talk to me. I also regularly sit at different places on the campus and then invite students to come and talk to me. I want our students to feel at home here.”

“I also want our students to feel free to talk about the use of language at the UFS. We love Afrikaans, English and Sesotho and are not going to fight about language. We are going to develop the use of Afrikaans so that more students can speak it – and this also goes for English and Sesotho.”

Prof. Jansen said that Kovsie students had to be balanced students. “Our students must also excel in sport, art, etc., because the development of students who are properly prepared for the workplace is what we strive for as a tertiary institution. Therefore we are going to establish an office that assists students in their career preparation and will offer students internships so that they can come into contact with leading firms in the commerce and industry sectors.”

“However, we shall also actively enhance our students’ learning experience and therefore we are going to send a group of first-year students overseas in the second semester this year to gain knowledge about issues like integration and collaboration.”

At the occasion Prof. Jansen announced that bursaries to study at the UFS in 2011 would be awarded to the two top Grade 12 learners of the school.

The Secondary School Witteberg had a 100% pass rate in the Grade 12 final examinations the past few years. In 2009 the school was seventh amongst the top 50 schools in the Free State Province. Five learners from the school were also amongst the top 20 learners in the Province last year. The school has already produced many top students for the UFS.
