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.

Amphitheatre to energise student life on the Qwaqwa Campus
2015-06-11

The Qwaqwa Campus of the University of the Free State is one of the fastest-growing rural campuses.

Since 2010, the campus has, among other things, built two new student residences, which provide accommodation for an additional 500 students. The old disused boiler room, which was used as a storeroom, has been converted into much-needed ablution and dressing room facilities at the sports fields.  The Faculty of Education now boasts a Technology, Engineering Graphics and Design Education laboratory. The project was funded by the Department of Higher Education and Training.

One of the student priorities is a common space in the form of an open amphitheatre in front of the library.

‘’The amphitheatre is a highly-welcomed structure on our campus as it will provide students with an informal environment to study, socialise and meet,’’ said the Campus Principal, Prof Prakash Naidoo.

‘‘We have erected this on an existing space that was already used for outdoor launches and events on the campus, and is in line with our thinking of energising student life on campus. In addition, we have complemented this with the use of solar energy, so that students can just plug in and charge their phones and laptops while they are in the amphitheatre.”

Excited students, Chibi Mosia and Tshilidzi Matshavha, in final-year Chemistry and Chemistry Honours respectively, concurred that the amphitheatre is a good project for the campus.

‘‘It is an important and distinctive feature for the campus as it adds to the growth of our beautiful campus,’’ said Mosia.

‘’It will also enhance the use of alternative energy sources to reduce the campus's carbon footprint,’’ added Matshavha.

The project is worth almost R2,5 m, and took 12 months to complete. The Department of Higher Education and Training also provided the funds for this project.
