SK Luwaca at UFS Safety Summit for off-campus students
Sikhululekile Luwaca, leader of the UFS Safety Champions, addresses a delegation at the Higher Education Safety Summit from 18-19 October 2019 at the Bloemfontein Campus.

A meeting of minds over student safety recently took place at Kovsies. The Higher Education Safety Summit saw a cohort of 165 students from the University of the Free State (UFS), Central University of Technology and Sol Plaatje University, collaborating with the heads of Protection Services from the respective institutions to devise a safety blueprint specifically focusing on the off-campus environment.

“The rental tribunal came on board to assist with rental disputes between students and landlords, in addition to accreditation issues being discussed,” Sikhululekile Luwaca, former SRC President of the Bloemfontein Campus and leader of the UFS Safety Champions that form part of the Unit for Institutional Change and Social Justice.

Luwaca further said that the Mangaung Metropolitan Municipality also committed to assist the universities in addressing crime and enforcing by-laws. “A strategic safety plan was developed around spatialisation and zoning of student communes, developing a system that will assist universities to establish where students stay by using technology such as geographic information system (GIS),” he added.

What were the objectives of the summit?
Being the first of many to come, the summit set out clear objectives which all stakeholders have committed to work tirelessly to achieve, both in the short and long term.

The goals of the summit were threefold. Firstly, the intention was to build capacity between students and staff of all institutions involved to implement programmes by transferring the skills and knowledge between one another.

Secondly, the idea was to gather and consolidate input from the various higher-learning institutions and by so doing diversify the solutions. Thirdly, the purpose of the summit was to create an official platform where partners may consult on interventions that will ripple from the local, to the provincial and further to national level.

Andiswa Msomi, Spatialisation Group Leader and the Safety Champions’ administrator said she appreciated the shift in perspective that the summit brought. “The summit brought to my attention that sometimes we focus so deeply on one aspect of a problem that we end up not seeing alternative solutions. Due to active participants, new solutions came up, new ideas were brought forth and more importantly, we were able to get other institutions on board,” she said.

What are some of the tangible outcomes?
Going forward, an internal report which focuses on crime prevention measures will be presented to all UFS stakeholders. An external report, which will be submitted by the Safety Champions to the government in January 2020, is expected to be integrated into the Provincial Crime Prevention Strategy.

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.
