WomensMonth Art exhibition honours courageous South African women
Winnie Madikizela-Mandela became affectionately known as the ‘Mother of the Nation’. She passed away on 2 April 2018. Winnie Madikizela-Mandela by Alf Khumalo on display at the Oliewenhuis Art Gallery.

Art in its many forms has always challenged controversial issues in national and international discourse. The exhibition in commemoration of Women’s Day, titled Speaking out and standing up: An exhibition in honour of South African women, highlights women’s voices by narrating their own life histories. 

In collaboration with the Oliewenhuis Art Museum, the Centre for Gender and Africa Studies (CGAS) at the University of the Free State hosted an art exhibition on 1 August 2018. The exhibition took place on the same day as the national #TotalShutDown protests challenging gender-based violence and rape across South Africa. The exhibition included numerous South African female artists who have combined art and activism and was curated by Yolanda de Kock from Oliewenhuis. The works are on display at Oliewenhuis until 26 August 2018.

The historical representation of South African women

“Tonight’s exhibition focuses on the historical and contemporary representation of SA women, and one woman that deserves acknowledgement, is Winnie Madikizela-Mandela,” said Dr Nadine Lake, Gender Studies Programme Director at CGAS. She also highlighted the fact that “Madikizela-Mandela’s life attests to the multifaceted nature of black women’s lives. Her life reveals that black women are not automatically regarded as agents in their own right, but face discrimination, isolation, and exclusion when they step out of the parameters defined for them.” 

Dr Lake furthermore asserted that, “South African Women’s Month and Day is a reflection and commemoration of women’s achievements but is increasingly being criticised by feminists across the country. While the constitution enshrines the rights of women and prohibits discrimination, it has become clear that there is a huge disconnection between an aspirational ideology and women’s lived realities.” 

Women should lead their own narrative

Sharon Snell, Chief Executive Officer of the National Museum, said, “The dominant voice about Women’s Day is to spoil women and to give them flowers and chocolates on the day, in the same way as for Mother’s Day.” 

Women’s Day has unfortunately been equated to the traditional role that women play. The purpose of Women’s Day is to change those perceptions and to highlight issues of inequality. Snell said, “It is time for women to lead their own narrative.”

The exhibition highlights the important intersection between art and activism and focuses on aspects such as gender-based violence, homosexuality, corrective rape, domesticity and intersectionality, consumerism and feminism, traditional and family histories, women’s and children’s rights, identity and gender, bullying and domestic violence. Snell emphasised the fact that art has not been silenced and has carefully been articulating these important messages around gendered and social inequalities.

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.
