Heinrich Janse van Rensburg’s is a 5th year medical student from the University of the Free State whose photo was highly commended at the Imperial College London’s Global Creative Competition: Medical Student Responses to COVID-19.

A late-night photo taken through a window at the Pelonomi hospital by a final-year medical student from the University of the Free State (UFS) was highly commended at the first Global Creative Competition: Medical Student Responses to COVID-19.

The competition, held by the Imperial College London, received more than 600 entries from more than 52 countries. The competition was held to bring together the global community of medical students to submit their creative responses to COVID-19 and to provide a platform for them to reflect on their personal and professional experiences during this challenging time.

Medical students from around the world could enter in two categories; visual and literary, and the winners were announced during a Global Awards Ceremony on 14 October.

Meaning behind the photo

Heinrich Janse van Rensburg’s late -night photo highlights the economic inequality that persists in South Africa. The photo was taken from the Pelonomi Hospital which is located in Heidedal, Bloemfontein, and shows the old, forsaken Dutch Reformed church in the foreground, shacks in the background with smoke billowing from the dwellings, where up to six people live in one room trying to stay warm during winter. They are built so close to each other that there can be no talk of effective social distancing.

According to Janse van Rensburg the theme of inequality in the South African milieu is further shown in the striking contrast between light and dark in the picture. “And now, with the COVID-19 pandemic placing a massive burden on an already struggling healthcare system the inequality is even more visible,” says Janse van Rensburg.

A little shocked 

He was a little shocked when he heard his photograph was highly commended. Janse van Rensburg says: “Imperial College London is a big institution and being an international competition I did not really expect a lot. There were participants from over 52 countries, and having seen some of the works that were submitted it feels special to be one of the students being noticed.”

Janse van Rensburg, who has never considered doing art, heard about the competition through the Faculty of Health Sciences platforms during lockdown level 5. He saw it as an opportunity to reflect, which has become even more imperative in times like these.

He says he does not go searching for art, but “notices” it from being conscious – something he thinks is important in medicine and life.

Value of creativity in promoting mental well-being

Dr Lynette van der Merwe, undergraduate medical programme director, School of Clinical Medicine, congratulated Janse van Rensburg, saying this commendation in an international competition underscores his talent and the value of creativity in promoting mental well-being.

“Heinrich’s artwork and showcase precisely what we aspire to develop in our exceptional UFS doctors-in-training: a professional with self-awareness, empathy and humanity.

“We initiated a Mental Health Awareness initiative and art competition in the School of Clinical Medicine in 2018 to promote creative expression as a means of supporting students’ mental health. Heinrich has won awards with his creative contributions every year, exhibiting his imaginative ability.”

Surgery and photography

Janse van Rensburg says he has always loved beautiful things and the meaning people attach to art is a good way to communicate that. He has applied for an internship at the Mitchells Plain hospital for when he completes his studies at the end of this year and is thinking of specialising in reconstructive or pediatrics surgery. Besides that, he would like to tap into his creative side and continue with the photography.

Her advice to farmers is that they should make sure they are aware of the total cost (investment and operating costs) of an irrigation system. In most cases the investment cost is low, but the operating cost over the lifetime of the system is high.

“It is very important to have a look at the total cost and to install the most economic system,” says Marcill Venter, lecturer at the University of the Free State (UFS), who has done research on the economic sustainability of water-pipe systems.

Irrigation systems important components for farming
This research comes at a time when many farmers are relying on their irrigation systems due to persistent drought and low rainfall during 2016. South Africa has also experienced an abnormal increase in electricity tariffs in recent years. Due to tariff increases which threaten the future profitability of irrigation producers, the Water Research Commission (WRC) has launched and financed a project on the sustainable management of irrigation farming systems. “I had the opportunity to work on the project as a researcher,” says Venter.

The heart of every irrigation system is the water pipes that bring life to crops and livestock, and this is what Venter’s research is about. “Water pipes are part of the whole design of irrigation systems. The design of the system impact certain factors which determine the investment and operating costs,” she says.

Mathematical system to help farmers
Venter and Professor Bennie Grové, also from the Department of Agricultural Economics at the UFS, designed the Soil Water Irrigation Planning and Energy Management (SWIP-E) programming model as part of the WRC’s project, as well as for her master’s degree. “The model determines irrigation pump hours through a daily groundwater budget, while also taking into account the time-of-use electricity tariff structure and change in kilowatt requirements arising from the main-line design,” says Venter. The model is a non-linear programming model programmed in General Algebraic Modeling System (GAMS).

Design of irrigation system important for sustainability

The main outcome of the study is that the time-of-use electricity tariff structure (Ruraflex) is always more profitable than the flat-rate structure (Landrate). The interaction between the management and design of a system is crucial, as it determines the investment and operating costs. Irrigation designers should take the investment and operating cost of a system into account during the design process. The standards set by the South African Irrigation Institute (SAII) should also be controlled and revised.

Water-pipe thickness plays major role in cost cuts
There is interaction between water-pipe thickness, investment and operating costs. When thinner water pipes are installed, it increases the friction in the system as well as the kilowatt usage. A high kilowatt increases the operating cost, but the use of thinner water pipes lowers the investment cost. Thicker water pipes therefore lower the friction and the kilowatt requirements, which leads to lower operating costs, but thicker pipes have a higher investment cost. “It is thus crucial to look at the total cost (operating and investment cost) when investing in a new system. Farmers should invest in the system with the lowest total cost,” says Venter.
