Dr Michael Pienaar, Senior Lecturer and specialist in the UFS Department of Paediatrics and Child Health being presented to the acting Chancellor by his supervisor Prof Stephen Brown.
A lecturer from the University of the Free State (UFS) says the need to improve the care of seriously ill children is a vital part of reducing preventable deaths and diseases, and this led him to investigate the use of artificial neural networks to develop models for the prediction of patient outcomes in children with severe illness. The study was done for his PhD thesis. 

This forms the basis for the PhD thesis of Dr Michael Pienaar, Senior Lecturer and specialist in the UFS Department of Paediatrics and Child Health, called, The Development and Validation of Predictive Models for Paediatric Critical Illness in Children in Central South Africa using Artificial Neural Networks. His thesis reports the development and testing of several machine learning models designed to help healthcare workers identify seriously ill children early in a range of resource-limited settings. Combining a systematic literature search and Delphi technique with clinical data from 1 032 participants, this research led to significant progress towards implementable models for community health workers in clinical practice.

Care for critically ill children is a mission and calling 

Dr Pienaar graduated with a PhD specialising in Paediatrics on Monday (12 December) during the Faculty of Health Sciences’ December graduation ceremony. It took him three years to complete this degree. His supervisor was Prof Stephen Brown, Principal Specialist and Head of the Division of Paediatric Cardiology in the Department of Paediatrics and Child Health in the Faculty of Health Sciences at the UFS. Prof Nicolaas Luwes and Dr EC George were his co-supervisors. 

“I have been working in paediatric critical care since 2019 and see the care of critically ill children as my mission and calling in life. At the outset of the project, I was interested in approaches to complex phenomena and wanted to investigate new methods for tackling these in healthcare. 

“I have been interested in technology since childhood and in collaborating with other disciplines since I joined the university in 2019. Machine learning seemed like a great fit that could incorporate these interests and yield meaningful clinical results,” explains Dr Pienaar the reason why he chose this topic for his thesis.

He hopes that, in time, this work will lead to the implementation of integrated machine learning models to improve care and clinical outcomes for children in South Africa. From a scholarship perspective, he continues, his hope is that this work draws interest to this field in clinical research and encourages a move towards incorporating these new methods, as well as skills in areas such as coding and design in the armamentarium of a new generation of clinicians.

Medicine chooses you

According to Dr Pienaar, he always had broad interests, of which medicine is one. “I am very grateful to have found my way in medicine and am humbled and privileged to be allowed to walk with children and their families on a difficult and important journey. I believe this profession will choose you and put you where you are needed if you give it time and are prepared to listen.”

He describes graduating as a complicated ending to this period of his life and the beginning of a next chapter. He was humbled by the graduation ceremony. 

“It was wonderful to graduate with undergraduates and postgraduates in my profession – I felt great pride and solidarity joining these new colleagues and specialists in taking the oath. I am certainly relieved, proud, excited, and happy. I am also very grateful to the university, my promotors, colleagues, friends, and family for supporting me through this process. I must confess, it is also slightly bittersweet, I loved working on this and do miss it, but look forward to the next exciting project. 

“I would like to thank my Head of Department, Dr (Nomakhuwa) Tabane, my supervisors, my family and friends once again. I would also like to acknowledge and thank the National Research Foundation (NRF) as well as the University of the Free State for their assistance with funding this research.”

SASOL TRAC laboratory launched at UFS Qwaqwa Campus

Some of the guests attending the launch of the Sasol TRAC Laboratory at the University of the Free State's (UFS) Qwaqwa Campus were from the left Prof Peter Mbati (Principal of the Qwaqwa Campus), Mrs Zimbini Zwane ( Communications Manager of Sasol Infrachem), Prof Gerhardt  de Klerk (Dean : UFS Faculty of the Humanities), Prof Fred Hugo
 Director of TRAC SA) and Prof Jack van der Linde (Director of RIEP at the UFS).

SASOL TRAC laboratory launched at UFS Qwaqwa Campus

The Research Institute for Education Planning (RIEP) of the University of the Free State (UFS) today unveiled the Sasol TRAC Laboratory at its Qwaqwa campus.

The laboratory will be used to help grade 10, 11 and 12 learners and educators from the Qwaqwa region to conduct the experiments from the physical sciences outcome-based curriculum.

“The Sasol TRAC Laboratory introduces learners not only to the latest technology used by engineers and other scientists in practice but also to stimulate the learner’s interest in the field of science in such a way that more of them will enter into science related careers,” says Mr Cobus van Breda, Co-ordinator of the TRAC Free State Regional Centre.

According to Mr van Breda the newly established Sasol TRAC Laboratory will enable RIEP to train learners and their educators in Physical Sciences.  The laboratory will consist of six work stations equipped with computers and electronic sensors.

“Learners from the Qwaqwa region will visit the Sasol TRAC Laboratory on regular basis to conduct experiments based on the curriculum.  Data will be collected with electronic apparatus and presented as graphs on the computer so that results can be analysed and interpreted,” says Mr van Breda.

“There is a serious shortage of suitable qualified teachers in maths and science in the Qwaqwa region.  Many schools in the region are not yet part of the RIEP project and are in dire need of assistance.  A large number of these schools are in remote areas not reached regularly by intervention programmes,” says Prof Peter Mbati, Principal of the UFS Qwaqwa Campus.

“The establishment of the Sasol TRAC Laboratory at the Qwaqwa Campus provides us the opportunity to engage with our community and assist in the development and training of these vital education subjects.  We are pleased that Sasol agreed to fund the project,” says Prof Mbati.

Students from the Qwaqwa Campus will also benefit from the TRAC programme.   “Some promising students will also undergo further training and become assistants for the TRAC programme,” says Prof Mbati. 

“Nurturing science and mathematical skills is of great importance in growing our national economy. Annually, Sasol invests more than R50 million in supporting mathematical and science education in South Africa. Our primary aim is to increase the number of learners gaining access to tertiary education in the science fields. Therefore, our Corporate Social Investment (CSI) education interventions at secondary school level focus on educator development and direct learner interventions such as the Sasol TRAC Laboratory,” explains Ms Pamilla Mudhray, CSI and SHARP manager at Sasol.

According to Ms Mudhray the implementation of the National Curriculum Statement for physical sciences in the further education and training (FET) phase from 2006, under resourced schools will need greater access to the tools and equipment necessary to teach the syllabus and fulfil the ideals of the curriculum.

TRAC South Africa is a national non-profit programme focused on supporting and expanding science, mathematics and technology education in secondary schools. The programme was first introduced to South Africa in 1994. In 2005, RIEP established the TRAC Free State regional centre on the UFS Main Campus in Bloemfontein.
