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.

New SRC elected on UFS main campus
2006-08-23

 Ms Loraine Kriek, third-year student in B Consumer Sciences, was elected as SRC President of the Main Campus of the University of the Free State (UFS) for 2006/2007.  Ms Kriek was a member of the Student Parliament in 2005/2006.

 The most students in the history of the UFS – 6 353 in total – voted in this year’s election.  There were only 44 spoiled votes.  Last year 4 846 students voted.

 “Other than last year, minor incidences of vandalism occurred on the Main Campus by students who were unhappy with the outcome,” said Dr Natie Luyt, Dean:  Student Affairs at the UFS.  According to Dr Luyt minor damage was caused to the Thakaneng Bridge and some other buildings on the Main Campus.  

 Kovsie Alliance obtained no proportional representation on the SRC, SASCO obtain 3 seats and the FF+Kovsies obtained 6 seats.  

 This representation gave Kovsie Alliance 1 seat, SASCO 14 seats and the FF+Kovsies 25 seats in the Student Parliament, which consists of 40 seats.

 Nine of the 18 SRC members were directly elected and nine on the basis of proportional representation (PR).   The PR system was introduced after amendments to the constitution of the Main Campus SRC were approved by the UFS Council in June 2005. 

According to Dr Luyt elections on the Vista Campus will take place today (Wednesday 23 August 2006) and Thursday 24 August 2006.  The results will be announced on Friday 25 August 2006.  The SRC of the Qwaqwa Campus will be elected on Friday 25 August 2006.  If there are no objections to the final results, it will be announced that same day.

The Central SRC, made up of representatives of the 3 campus SRCs, will be announced towards the end of September 2006.
