The No Student Hungry team gearing up to start distributing food parcels to the selected students.
The UFS is one of the many institutions of higher learning where food insecurity is an active issue. However, the
No Student Hungry Programme is one of the initiatives launched at the university to assist in fighting food insecurity at the institution.
The purpose of the programme
Since its inception in 2011, the initiative has assisted many students in acquiring a healthy meal. Additionally, the Food Environment Office also hands out food packages, so that students can continue to achieve academically. “We are trying to develop a healthy environment for students and make it easier for them to have a nice and healthy meal,” stated Annelize Visagie, who heads the Food Environment Office at the UFS. The Food Environment programme is spread out on all three campuses, each with its own facilitators. Furthermore, the programme mainly caters for students who are not funded by the National Student Financial Aid Scheme (NSFAS) but who are excelling academically. The abovementioned students apply for assistance online, and a list is then drawn up of students who receive assistance for the year.
Alternative solutions to keep the initiative running
On the Bloemfontein Campus, the No Student Hungry Programme will be catering for 200 students in the 2022 academic year, assisting them with a daily nutritious meal. Additional food parcels are also handed out to provide further assistance. “We give food parcels to the students on the list every Tuesday and Thursday at the Thakaneng Bridge,” Visagie highlighted. However, she argues that catering for the student population through this programme can be a challenge, as the demand for assistance is growing rapidly and the ability to assist is limited. The programme relies on partnerships and sponsors to assist the student body. In fact, the coordinators of the programme currently have a memorandum of understanding with Tiger Brands according to which they deliver around 100 food parcels for distribution.
In addition, the coordinators have put in place alternative measures to ensure that they can provide more food to students. “The
Kovsie Act Office, in partnership with the
Department of Sustainable Food Systems and Development, has started a food garden where healthy and nutritious produce are grown, in order to add value to the distribution,” she indicated. Although the programme can only assist to a point, students who are in desperate need of assistance are never turned away. In fact, the
Social Support Unit at Thakaneng Bridge usually assists students with food vouchers for a maximum of four days.
A commitment to teaching healthy eating habits
The programme is not only committed to curbing food insecurity, but also to ensuring that students have a healthy and balanced diet. As such, a booklet is being issued by the
Department of Nutrition and Dietetics in collaboration with the Department of Sustainable Food Systems and Development, which contains ways in which students can make a healthy meal using some of the ingredients offered in the food parcels.
“We want to teach students how to eat healthy in the cheapest way, because they don’t have a lot of money to buy expensive food products,” Visagie argued.
Mathematical methods used to detect and classify breast cancer masses

Examples of Acho’s breast mass
segmentation identification
Breast cancer is the leading cause of female mortality in developing countries. According to the World Health Organization (WHO), the low survival rates in developing countries are mainly due to the lack of early detection and adequate diagnosis programs.
Seeing the picture more clearly
Susan Acho from the University of the Free State’s Department of Medical Physics, breast cancer research focuses on using mathematical methods to delineate and classify breast masses. Advancements in medical research have led to remarkable progress in breast cancer detection, however, according to Acho, the methods of diagnosis currently available commercially, lack a detailed finesse in accurately identifying the boundaries of breast mass lesions.
Inspiration drawn from pioneer
Drawing inspiration from the Mammography Computer Aided Diagnosis Development and Implementation (CAADI) project, which was the brainchild Prof William Rae, Head of the department of Medical Physics, Acho’s MMedSc thesis titled ‘Segmentation and Quantitative Characterisation of Breast Masses Imaged using Digital Mammography’ investigates classical segmentation algorithms, texture features and classification of breast masses in mammography. It is a rare research topic in South Africa.
Characterisation of breast masses, involves delineating and analysing the breast mass region on a mammogram in order to determine its shape, margin and texture composition. Computer-aided diagnosis (CAD) program detects the outline of the mass lesion, and uses this information together with its texture features to determine the clinical traits of the mass. CAD programs mark suspicious areas for second look or areas on a mammogram that the radiologist might have overlooked. It can act as an independent double reader of a mammogram in institutions where there is a shortage of trained mammogram readers.
Light at the end of the tunnel
Breast cancer is one of the most common malignancies among females in South Africa. “The challenge is being able to apply these mathematical methods in the medical field to help find solutions to specific medical problems, and that’s what I hope my research will do,” she says.
By using mathematics, physics and digital imaging to understand breast masses on mammograms, her research bridges the gap between these fields to provide algorithms which are applicable in medical image interpretation.
