Since the approval of the University of the Free State (UFS) internationalisation strategy for 2018-2022, the UFS community and staff members of the Office for International Affairs (OIA) have been working hard to try and realise the goals stated in the strategy. The policy states “the university's’ commitment to developing curricula that are locally relevant, globally competitive and connect to multiple knowledge paradigms”. Furthermore, “We expect that the new internationalisation strategy will advance the international positioning of the university, and synergise the existing rich international activities into intentional, comprehensive internationalisation processes”.

In an effort to realise the said expectations through the university’s inbound mobility programme, the Department of Afrikaans and Dutch, German and French in the Faculty of the Humanities has hired Baptiste Becret, an exchange student from French partner university, Science PO Bordeaux, as French tutor for the first semester of 2020. This collaboration by the two departments endeavours to achieve the university’s vision of developing its students’ international and intercultural competencies through internationalisation at home. Equally, this initiative speaks to a critical aspect of internationalisation, the “purposeful integration of international and intercultural dimensions into the formal curriculum for the UFS students within the domestic learning environment”.

Being the only Frenchman on campus

“I was the only Frenchman on campus and at the university, which I rather enjoyed. I learned at the beginning of this year, in January, that I could share my culture and language by helping students participating in the first- and second-year French courses at the university. For my part, I was attached to the Faculty of the Humanities. I've already had experience as a tutor in France, so I wasn't very stressed at the idea of being in front of a class. I enjoyed trying to teach my mother tongue. My contact with the French teacher was good. He gave me a lot of freedom to do the activities I wanted to do.

I didn't think that passing on my knowledge to the first-year class would be so difficult. Indeed, for some of them, they have never spoken a word of French. But the atmosphere improved from class to class after a shy start. I hope I was able to help them as best I could. In any case, I was very happy to teach them and to assist them in their various difficulties with the language. For the second-year class, the atmosphere was a little different. The class was smaller, the students already knew each other well, and they were pretty close. Additionally, their language level was already good. 

All this to say that being a French tutor was a great experience. It was enriching for both parties (students and me). Of course, I tried to do the best I could, and I took advantage of the free time my schedule gave me to share a little bit of my home country. So, I advise future international students – if they feel comfortable with that – to give it a try. It's only two hours a week with a little bit of extra money. Finally, I would like to thank the International Office for informing me of this opportunity, the people involved in the programme, including my coordinator, the French teacher, and especially the students who have been super cool to me.”

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.
