The University of the Free State is sad to learn of the passing of alumnus and award-winning Sesotho literary giant, Dr KPD Maphalla.
The literary works of Dr Khotso Pieter David Maphalla, like many other African writers and artists, were influenced and characterised by his own era of powerful forms of oppression and exclusion from dominant literary discourses. In his own right and through his writings of poetry, novels, short stories, and kodiamalla (dirge), he articulated a deliberate political and social protest and pushed for a place for African languages in literature at the height of apartheid.
“He entered the professional scene with his ground-breaking novel, Kabelwamanong, in 1982 at the age of 27. His career actually started in 1971 while he was still at school. Since his first novel, he has produced at least two books annually, covering the genres of poetry, novels, dramas, and short stories. As a dramatist, Dr Maphalla has written a number of excellent and educative radio dramas for the then Radio Sesotho (now Lesedi FM),” said his long-time friend and Head: African Languages at the University of the Free State, Dr Nyefolo Malete.
“It was for this writing prowess that he received recognition from the UFS when he was awarded an Honorary Doctorate in Literature by the Department of African Languages during a momentous ceremony on the Qwaqwa Campus in 2007,” added Dr Malete.
Dr Malete also revealed that, despite losing the use of his right hand after suffering a stroke following a car accident in the late 1990s, Dr Maphalla continued writing using his left hand. “He was adamant that, what he referred to as his ‘supposed disability’, would not deter his passion for writing.”
Dr Maphalla’s work has also produced numerous scholarly studies by the likes of Profs Moleleki Moleleki (protest poetry), Thapelo Selepe (lament and protest poetry), and Dr Seema Seema (process of cross-cultural communication). He was a committed Qwaqwa community member, who was also instrumental in the founding of Qwaqwa Community Radio (2000) and Metjodi Writers (2006), among others. He has written more than 70 books, many of which have been prescribed texts in schools.
Some of the awards he has won include:
South African Centre for Digital Language Resource (SADiLar) Sesotho Lexicographic Unit (Sesiu sa Sesotho) Lifetime Award for outstanding literary works and for promoting Sesotho literature (2019).
The Literature Festival and the University of the Free State Award for enormous contribution to Sesotho literature by a South African writer (2019).
Lifetime Achiever Award in Literature awarded by the Department of Arts and Culture (2005).
M-Net Book Prize for Sesotho poetry (2005). The first and thus far the only Sesotho author to have received this honour.
M-Net Book Prize for best novel (1996).
De Jager-HAUM Literary Award for his volume of short stories, Mohlomong Hosane (1993).
Thomas Mofolo Trophy for Best Novel, Best Poetry, and the Overall Award (1992).
Thomas Mofolo Trophy for Best Poetry (1991).
Dr JJ Moiloa Floating Trophy for Best Sesotho Poetry Book of the Year, Kgapa tsa ka (1985).
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.
