Takudzwa Nyamunda represented the UFS at the latest Commonwealth Futures Workshop where youth from across the globe convened to develop solutions for social issues.


Gender-based violence, global warming, and inequality are just some of the challenges faced by societies internationally. Examining this and other topics Takudzwa Nyamunda represented the University of the Free State (UFS) at the Commonwealth Futures workshop which convened at the Durban University of Technology (DUT). Participants from 13 nations gathered from 11-14 March 2020 to discuss the future of the world.
 
Over the course of four days, student leaders explored ways of bringing peace and nonviolence to the challenging issues we are facing in the world, under the theme: Reimagining Peace. The workshop was organised by the DUT in collaboration with the Association of Commonwealth Universities (ACU) and the British Council. 

The voice of young people 
International forums such as the Commonwealth Futures workshop are to Nyamunda a prerequisite in these modern times. Nyamunda believes that global problems warrant global solutions. According to the Industrial Psychology Master’s student, young leaders have a crucial role to play in nation-building. 

“My experience proved to me that the differences that come out of our diversity are indeed a source of strength demonstrated by the rich insights that came out of the conference,” said Nyamunda who is also an employee of the UFS Department of Human Resources. 

Producing practical solutions
The three-tiered workshop aimed to bring change to campuses across the world, in communities and beyond. This was the third workshop in the series which has taken place in India and the UK. The outcomes will directly feed into the 2020 Commonwealth Youth Forum to be held in Kigali, Rwanda later this year.

The group of students worked together to develop tangible solutions that address shared global issues such as gender-based violence, climate change and inequality. Joining the young leaders were expert speakers and organisations including the International Centre of Nonviolence, the Gandhi Development Trust, as well as the Commonwealth Countering Violent Extremism (CVE) Unit.

Global solutions for global problems
The Commonwealth states that with more than 60% of the Commonwealth’s 2.4 billion people younger than 30, the voices of young people have never been more important. Students across the globe are setting new agendas for social debates, challenging communities and governments to listen and work with young people to develop solutions to these intersecting issues and bring about real change.

In joining forces with other young thought leaders from around the world, Nyamunda drew on his experience as an International Students Association Founder and first President, the former 2017 Student Representative Council (SRC) member for International Students, and the Vice-Chairperson of the South African Board for People Practices: UFS Chapter. 

As one of the 40 delegates from across the globe, Nyamunda was given a sense of hope after he witnessed how keen young people are to build a better future.

Mathematical methods used to detect and classify breast cancer masses

Examples of Acho’s breast mass

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.
