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 first-year students’ swimming gala is always a much-anticipated event, especially after the participants have rubbed shoulders with residence competitors at the first-year athletics. This year’s gala, which took place on 5 February 2016 at the Lindsay Saker swimming pool on the Bloemfontein Campus, proved as exhilarating as always.

The body painting competition, held through the University of the Free State Student Representative Council (SRC) portfolio of Media & Marketing, and sponsored by ABSA, was re-introduced.

Colleges in colour

Before the swimming, spectators had the opportunity to look at the body painting creations presented by each college. Colleges chose one of ten themes randomly. Nonetheless, true artistry was on display. South College were awarded the body painting floating trophy.

When asked about this year's competition, SRC Media & Marketing, Peo Segano, had this to say: "I questioned the relevance of it, but I got the opinion of the residence committees and how they felt about it.
“The majority voted for it to be re-introduced, and ABSA was more than happy to sponsor the paints and some treats.”

Soon after that, it was down to the business. The swimming started, and each residence was cheering ecstatically for their fellow freshmen as everyone waited in anticipation to see who would be crowned the kings or queens of the water.

Although many had sung their voices away, they continued to show their spirit through dance and movement. Then, residences were ready to hear whether it had all paid off. Armentum showed consistent effort in this regard, thus ensuring them of the spirit trophy.

To close off the festivities, the final announcements were made. Sonnedou was crowned the female residence winners, while Abraham Fischer (Vishuis) received the title of best male residence.
