- Description: Healthcare services within a hospital setting are the basic aspects for the success of service delivery and staff performance in this regard. The paramount component of human resources makes a positive contribution to a healthcare system. Recently, it has been recognised that the performance of healthcare personnel ought to be a key factor for a sustainable performance system. Nevertheless, it is generally known that healthcare workers fail to accomplish the anticipated outcomes of health interventions. This concept leads to the research question: Why is the public sector known for poor service delivery and poor performance? This study aims to determine the factors that impact on the health worker’s performance in a tertiary hospital in South-Africa. A framework will be carefully constructed and cautiously implemented to improve and develop the performance of healthcare workers in this hospital. The vast scope and population involved in this study make a quantitative research approach most suitable, along with a non-probability purposive sampling method. A survey method using an electronic questionnaire that was circulated via a web survey, and a paper-based questionnaire that was distributed within the hospital were used to obtain a diverse perception of the healthcare workers. Data analysis included determining factors, group differences and correlations using the SPSS-27 program. The target population included all healthcare workers in the tertiary hospital – from junior employees to senior management level staff. Statistical data analysis collected for this study revealed four major factors (politics-related resources, resource, training and socioeconomic) that play a major role in the trends of performance culture at the selected tertiary hospital. These results lead to the understanding that the hospital is currently experiencing inadequate human resources management components such as recognition of employees who perform above expectations; execution of a performance appraisal system; lack in implementing the annual salary increase; unfavourable working conditions (lack of resources); troublesome management skills, and insufficient feedback on performance outcomes. These features are directly associated with the quality and degree of the performance of healthcare personnel. Based on the results, a management framework was proposed. The framework consists of activities that will improve the healthcare profession; strengthen expertise and knowledge; develop management skills; enhance knowledge through research and, ultimately, upgrade the performance of healthcare personnel. , Thesis (MPH) -- Faculty of Health Sciences, Public Health, 2021

- Description: Marine macro-algae are a good source of potential primary and secondary metabolites. Phytochemicals of the samples were extracted using methanol and water. This study evaluated the phytochemical constituents, antioxidant activity and antidiabetic activity of selected red marine macro-algae sampled from Gqeberha, South Africa. The species collected were identified as Gelidium pristoides, Scinaia furcellata and Portieria tripinita using DNA barcoding. Results showed the presence of several phytochemicals such as saponins, phenols, flavonols, tannins, proanthocyanidins and flavonoids. Methanol was a more effective polyphenol extraction solvent than water. Gelidium pristoides (H2O) was observed to contain the highest phenol and proanthocyanidin content, which correlated to Gelidium pristoides (H2O) having the greatest FRAP and DPPH radical scavenging activity IC50 at 0.227. Portieria tripinita (MeOH) extract had the greatest flavonoid content. Flavonol content was high for Scinaia furcellata while the highest tannin content was observed in both H2O and MeOH extracts of Gelidium pristoides. All the selected marine macro-algae species showed concentration-dependent reducing power. The extract with the highest ABTS scavenging activity was Gelidium pristoides (MeOH) IC50 at 0.227. Portieria tripinita was the only species that showed Nitric oxide scavenging activity, with (H2O) extract showing the highest activity IC50 at 3.052. Only MeOH extracts of Gelidium pristoides and Scinaia furcellata showed very slight α-amylase inhibition, however, all extracts successfully inhibited the activity of α-glucosidase with the exception of the H2O extracts of Scinaia furcellata. All crude extracts of Gelidium pristoides, Scinaia furcellata and Portieria tripinita showed no significant/weak effect on glucose uptake and utilization by C3A cells following 24 hours of treatment, with the exception of the aqueous extracts of Scinaia furcellata at the highest concentration of 100 μg/ml. The in-vitro MTT cytotoxicity assay revealed that only MeOH extracts of Gelidium pristoides and Scinaia furcellata had a 15 significant toxic effect on C3A hepatocytes at concentrations of 100 μg/ml and 25μg/ml, respectively. Portieria tripinita aqueous extract showed cytotoxicity when evaluated using Hoechst 33342/Propidium iodide (PI) dual staining. , Thesis (MSc) -- Faculty of Science and Agriculture, 2021
