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 31st Congress of the International Limnological Society (SIL) was recently held at the Cape Town International Convention Centre (CTICC).

Prof. Johan Grobbelaar from the Department of Plant Sciences at the University of the Free State (UFS), who is also the chairperson of the local organising committee (LOC), worked hard for six years to secure the bid to host the congress in South Africa. The LOC consisted of Prof. Grobbelaar, Prof. Brian Allanson, Prof. Jenny Day, Dr Carin van Ginkel and Dr Mike Silberbauer.

SIL was founded in 1922 to further the study and understanding of all aspects of limnology, the science of inland aquatic ecosystems and their management.

Congresses are held every three years and this was the first time that SIL met on the African continent.

Almost 400 delegates from 42 countries attended this congress where the state of the science of limnology was presented with two keynote speakers, six plenary lectures, 230 oral and 76 poster presentations, mostly running in five parallel sessions. Exhibitions displayed some of South Africa’s role players as well as the latest equipment from abroad. Delegates could also join pre- and post-congress excursions and the new SIL journal, Inland Waters, was launched at the congress.

Many of the presentations dealt with water as a limited resource, pollution problems and the impact of climate change. The congress resolved that SIL would play a more prominent role in creating awareness of problems impacting on inland waters and also afforded solutions. The 32nd SIL congress will be held in Budapest, Hungary in 2013.
