UFS Africa celebration — I am not African because I was born in Africa, but because Africa was born in me,” Kwame Nkrumah, Ghana’s first president, and a founding father of the African Union.

Since the African Union’s establishment in 1963, the continent marks Africa Day on 25 May annually. To commemorate the achievements made by African leaders 56 years ago to decolonise the continent and pave the way for a united front on the global stage, the University of the Free State (UFS) hosts various events.

Ubuntu our beginning, ubuntu our ending

The university celebrated Africa Day a day early this year. The Office for International Affairs coordinated the 2019 Africa Day Reflection and Celebration on 24 May 2019 at the Bloemfontein Campus. A dialogue session delved into the question of what ubuntu has evolved to mean in modern-day society and how best it can be embodied.

Moderator of the dialogue, Ace Moloi, reckoned that “we have a right not only to give ubuntu but to demand and invoke it from other people.” Staff, students and panellists engaged on the aphorism umuntu ngumuntu ngabantu and whether the philosophical principle is a pragmatic way of doing things or is only referred to when self-correcting.

Prof Colin Chasi, from the UFS Department of Communication Science, touched on how ubuntu is embedded in many Nguni languages. A case in point being the implied presence and connectivity typical found in indigenous language greetings. Other panellists including Prof Karin van Marle( Public Law lecturer at the UFS), Thapelo Mokoatsi,History lecturer at the UFS and Matau Setshase, UFS researcher, made contributions on decolonisation, individual identity, reconciliation, social issues, and traditional healers. The consensus reached was that a lot work still needs to be done in understanding and living the values represented by ubuntu.

Qwaqwa Campus Celebration

The Office for International Affairs (OIA) also hosted the first Annual Africa Day Student Dialogue on the Qwaqwa Campus under the theme: Health, Wellbeing, Access, Social inclusion, Equity and Equality on the African continent.

Africa Day Memorial Lecture

Presenting the 2019 Africa Day Memorial Lecture, Prof Francis Nyamnjoh, from University of Cape Town, delved into the topic of Ubuntuism and Africa: Actualised, Misappropriated, Endangered and Reappraised. “I seek to give currency to concepts such African communitarianism, ubuntu, Africanness, Afrocentricity, Afrocentrism, Africanity, Afrikology, humanness, wholeness and reciprocal altruism,” he said.

Hosted by the Centre for Gender and Africa Studies on 22 May 2019 the annual lecture is a calendar constant which reflects on the importance of celebrating the continent and its people.

Migration debate unpacked borders

The UFS Debate Society reflected on borders and migration in Southern Africa on 21 May 2019. The debate unpacked the topic: The Southern African Development Community should develop a free internal migration policy.

Lecturers also delivered presentations that dissected African societies, the nine frontier wars between the British and amaXhosa that formed South Africa’s borders, and the influence of labour and capital on migration. In closing, African international students shared their lived experiences, hardships and triumphs within the continent.

Mathematical methods used to detect and classify breast cancer masses

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.
