The purpose of this study was to look at how principals and educators managed and experience the implementation of Quality Assurance policies in secondary schools in KwaZulu Natal focusing on the bttegrated Quality Management System that is currently in place. This study was designed as a qualitative exploratory and descriptive survey. Data was collected in 2007 by visiting schools and conducting interviews with the principals and educators. School managers fell into two groups. One group was positive about Integrated Quality Management System and other group negative. Even though there were differences, all agreed that lntearated Quality Management System was good if it was to be introduced at a pace suitable to the educators. Educators preferred Integrated Quality Management System to systems that were not transparent. They then recommended that Integrated Quality Management System should not be linked to the educators' remuneration as this destroys what could be good about IQMS / Educational Studies / M.Ed.

Workplace violence directed at student nurses in training in psychiatric institutions is a significant concern as it negatively affects the quality of learning and causes the students to have a negative perception of nursing as a profession. The absence of scientific data describing the perceptions of student nurses about workplace violence and their clinical learning outcome motivated the researcher to conduct the study. Quantitative, descriptive research was conducted to explore the influence that workplace violence will have on clinical learning outcomes of student nurses who are studying psychiatric nursing at psychiatric institutions in KwaZulu-Natal, in South Africa. Data was gathered using a 71 question questionnaire, which was adapted from the one used by Hewett (2010). With the necessary permission from the health authorities, the campus principals and the nursing students, a group of 4th year student nurses (n=163) from 6 campuses of the KwaZulu-Natal College of Nursing (KZNCN) who have worked in psychiatric units for at least 3 months and longer participated in the study. The study highlighted the types of workplace violence encountered by student nurses, the effects of workplace violence on students’ academic performance and the barriers to the reporting of workplace violence encountered by the student nurses. The study revealed that there is a large amount of non-physical, some physical and a few incidents of sexual violence directed towards the student nurses at the psychiatric institutions, and that it has a negative impact on student learning. The recommendations emanating from the study support the idea of a shared responsibility between healthcare and education institutions and the focus is on preparing and equipping the student psychiatric nurses to confront, withstand and break the cycle of workplace violence. / Health Studies / M.A. (Nursing Science)

A qualitative study was undertaken in Pietermaritzburg to unveil the experiences and challenges of WLWHIV as perceived by social workers as well as to explore and describe the experiences of social workers in rendering services to these women. Explorative, descriptive and contextual research designs were employed for the research process. Purposive and snowball sampling techniques were utilised to recruit participants who met the set criteria. Face-to-face semi-structured interviews were conducted with thirteen participants. Data obtained were transcribed and analysed applying Tesch‘s eight steps (Creswell, 2009). Data verification was guided by Guba‘s model (Krefting, 1991). The findings revealed the existence of strained relationships between WLWHIV and their partners and ineffective delivery of social work services to WLWHIV. Based on the findings, it is recommended that specialised training for social workers on issues related to death and dying and services for children of WLWHIV be incorporated in the guidelines for social work practice / Social Work / M.A. (social Work)

The purpose of the study was to explore and describe the lived experiences of neophyte professional nurses working in ICU during their first year post graduation with the aim to discover strategies to support the nurse in critical care unit. An explorative, descriptive, interpretative qualitative design was conducted to uncover the nurse’s experiences. A purposive sampling was used which is based on belief that the researcher’s knowledge about the population can be used to hand pick sample elements. Data was collected through in-depth unstructured interviews and written narratives. Collaizi’s method of data analysis was used. The study findings revealed that neophyte professional nurses experienced difficulties and challenges in adjusting to the unit because of lack of mentors emanating from the shortage of staff. Nurses experienced mixed feelings regarding the relationship with colleagues in terms of support received. / Health Studies / M.A. (Health Studies)

Submitted in fulfilment of the requirements of the degree of Master of Technology: Biotechnology, Durban University of Technology, 2014. / Cyanobacteria contain phycocyanin a light harvesting pigment found to have numerous biotechnological applications, such as: a natural colorant in food and cosmetics, fluorescent tags employed in clinical and immunological research and also in therapeutic processes. Successful phycocyanin production depends on growth characteristics, ability to accumulate high quantities of the pigment, and an effective downstream process. Therefore, the aim of this research was to optimize the extraction method and production by determining the optimal cultivation conditions for phycocyanin producing cyanobacterium. This cyanobacterium was isolated from a hypersaline water body in Kwa-Zulu Natal, and subsequently purified using traditional streak and spread plate techniques. Different cell disruption techniques and a range of buffers were evaluated for the extraction of phycocyanin. The buffer concentrations and pH was subsequently optimized. Results showed that maximum phycocyanin was extracted when cells were suspended in 50mM sodium phosphate buffer (pH-7.5) supplemented with 10 % lysozyme and then disrupted using the freeze–thaw method at -20 & 4°C. The UV-Vis absorption spectral scan of the crude extracted pigments showed a peak at 620 nm. This corresponds to phycocyanin production. Unwanted proteins were removed using a 25and 50% saturated ammonium sulphate precipitation, followed by dialysis. SDS-PAGE showed two subunits with molecular masses of 19 and 20 kDa. These masses corresponded to phycocyanin α and β subunits. Furthermore, a food grade purity ratio (A615/A280) of 1.20 was achieved. The effects of various abiotic factors (temperature, light and pH) on growth and phycocyanin production of the Cyanothece sp. was investigated. Temperature ranging from 20-45°C and pH (5-10) was evaluated for 2 weeks. Cultures were then subjected to four photoperiods (24:0, 18:06 12:12 and 8:16 h light: dark) three light intensities (25, 75 and 125 µmol photons per m2 per –s) at varying wavelengths i.e. blue, red and green and Grolux light. Ideal conditions were observed at 35°C, 125 µmol photons.m2.s-1 of Grolux light for a 16:8 light and dark photoperiod. It was observed that the highest biomass and phycocyanin production was found to be at 35°C, temperatures below or above resulted in a decrease in both growth and pigment synthesis. Phycocyanin concentration changed in response to light quality and intensity. A significantly higher (p<0.05) phycocyanin yield was found when the culture was exposed to 125 µmol photons.m2.s-1 of Grolux light compared with the other three light conditions. Using Design of experiments, a series of fractional factorial experiments were carried out to optimize media components for pigment production. The final optimized growth medium was determined from a central composite design using response surface plots together with a mathematical point-prediction tool and consisted of 2g/L NaNO3, 0.06g/L K2HPO4, 0.12 g/L MgSO4.7H2O, 0.033 g/L CaCl2.2H2O, 100g/L NaCl, 12mL minor nutrients and 0.5 trace metal. A 72 % increase in phycocyanin was observed. This research revealed that this particular Cyanothece sp. shows great potential as a reliable source of phycocyanin.

Submitted in fulfilment of the requirements of the Master of Technology degree in Cost and Management Accounting, Department of Management Accounting, Durban University of Technology, Durban, South Africa, 2015. / Environmental degeneration, market pressures and stricter regulation and waste legislation has placed organizations under tremendous pressure to change their current processes and adopt cleaner production (CP) techniques and technologies. However, in countries like South Africa, CP implementation still remains low. In light of this problem, the government has made efforts to promote CP among industries by forming a support structure called the RECP (resource efficient cleaner production), as a strategy to encourage organizations to embrace this change and move away from the tradition end-of-pipe technologies towards CP technologies. This study is based on a case study of a paper manufacturing company in Kwadakuza, KwaZulu-Natal. The aim of this study was to use Environmental Management Accounting (EMA) to identify benefits of CP. Paper manufacturing consumes large amounts of natural resources and generates excessive wastes. Hence, the operational activities of paper mills have a negative environmental impact. However, the scope of this study was limited to the steam generation process and focused mainly on the efficiency of the current coal-fired boilers used in the boiler plant. The research methodology used in the study was both quantitative and qualitative involving triangulation. Data was collected by means of a questionnaire, semi-structured interviews and documentary review. The company uses old, obsolete boilers to generate steam. It had been discovered during a cleaner production assessment (CPA) of the process that the process uses large amounts of coal and generates excessive boiler ash (waste). This boiler ash also contains approximately 20 percent unburned coal present resulting in major losses to the company. Furthermore, the company has also experienced regular breakdowns during the year resulting in loss in production and high maintenance costs. Hence, it was concluded that the steam generation process was inefficient and that the boilers were not operating as per technological specification. However, management was unaware of the huge losses incurred due to raw material losses, more especially the coal used in the process. Environmental costs were also inaccurately calculated and thus underestimated. Hence, the ‘true environmental’ costs were not considered during strategic decision making. Over the last two decades, EMA has emerged as an important approach by organizations wanting to improve their environmental and economic performances. However, despite the many pilot projects conducted that demonstrated the positive impact that EMA has on an organization, EMA implementation remains slow and lagging in South Africa. EMA is an environmental management tool that traces environmental costs directly to the processes and products that are responsible for those costs, thereby highlighting problem areas that need to be prioritized when considering the adoption of CP. The literature review on the role and impact of implementing EMA and the benefits of adopting CP was presented to determine and outline views and findings of past researchers. Previous researchers identified that traditional costing systems did not adequately account for the actual environmental costs incurred by companies as much of these costs were hidden under overhead accounts. Hence, production costs were high, resulting in incorrect profit margins being set and ultimately impacting on company profitability. The main cause of this was that non-product output costs were added to production cost instead of being separately recorded as ‘non-product’ output. These costs are actually environmental costs as they represent waste. Material Flow Cost Accounting (MFCA), a tool of EMA, was considered as an appropriate method to implement to accurately calculate non-product output costs. MFCA made managers aware of the true magnitude of their losses and inefficiencies of current technology by increasing the transparency of non-product output costs (environmental costs). MFCA was further used to benchmark non-product output costs against technological standards and best available technological standards to highlight the economic and environmental benefits of adopting CP techniques and technologies. Based on the findings, one recommendation is that the company should consider restructuring their conventional costing system and adopt an EMA system instead. The use of an MFCA model had been suggested. This model was used by the Economy, Trade and Tourism industry in Japan to identify non-product output and improve efficiency of production processes. In addition, findings revealed that the company should implement CP techniques in the short-term to ensure that boilers are functioning according to technological specification. This will result in economic and environmental benefits for the company. However, greater savings potential is available in the long-term, by changing current technology and adopting state-of-the-art technologies. This would, however, require greater investment needs of the company to taken into consideration during strategic decision making.

Submitted in complete fulfillment of the requirements for the Degree of Master of Technology: Biotechnology, Durban University of Technology, 2012. / Immunomodulation using plants is of primary interest in scientific communities because it provides an alternative to conventional chemotherapy for a wide range of diseases. It is based on the ability of the plants to effectively modulate immune functions, thus being able to promote positive health and maintain the body’s resistance to infection. This research is aimed to evaluate the immunomodulatory potential of fourteen traditional leafy vegetables from Kwa-Zulu Natal, South Africa on human peripheral blood mononuclear cells (PBMC). In this study the methanolic and aqueous extracts were screened for lymphocyte proliferation using the MTT assay. The cytokine response was evaluated by measuring the secretion of interleukin 10 (IL-10) and interferon-gamma (IFN-γ) using the ELISA assay. The subpopulation of T cells viz., CD4+, CD8+, NK and B cells were measured by flow cytometry. Most of the methanolic extracts stimulated PBMC’s whilst a few suppressed lymphocyte proliferation. Most of the aqueous extracts were inactive. The methanolic extracts of Amaranthus hybridus and Centella asiatica stimulated PBMC’s and showed an increase in IFN-γ secretion and the CD8+ cytotoxic T cells and B cells. Thus, they induced the Tc-1 immune response and stimulated cell mediated immunity. The methanolic extracts of Asystasia gangetica, Bidens pilosa, Emex australis, Justicia flava Momordica balsamina, Oxygonum sinuatum, Senna occidentalis and Sonchus oleraceous and the aqueous extracts of Amaranthus spinosus and Asystasia gangetica, Ceratotheca triloba, Oxygonum sinuatum, Physalis viscosa and Sonchus oleaceous stimulated PBMC’s and showed an increase in IL-10 secretion and the CD8+ cytotoxic T cells and B cells. Thus, they induced the Tc-2 immune response and stimulated humoral immunity. Also, the methanolic extracts of Amaranthus spinosus and Ceratotheca triloba and the aqueous extracts of Bidens pilosa and Justicia flava increased both IL-10 and IFN-γ secretion and the CD8+ vii cytotoxic T cells indicating the stimulation of both the Tc1 and Tc2 cytokine profiles. The elevated secretion of IFN-γ and IL-10 caused by the extracts can be attributed to the CD8+ cytotoxic T cells and B cells. The findings of this study show that leafy vegetables hold promise as immunomodulatory candidates. They may enhance cell-mediated immune functions by a pro-inflammatory response whilst some can promote humoral immune functions by means of an anti-inflammatory response. Further investigation should be considered on the effect of the extracts on other immune parameters. / National Research Foundation

Submitted in fulfilment of the requirements for the Degree in Masters of Technology Nursing, Faculty of Health Sciences, Durban University of Technology. 2014. / Background The KwaZulu-Natal College of Nursing trains students to be professional nurses through the R425 programme. Teaching and evaluation are done in English, although the majority speak isiZulu as their home language. Due to inequalities in the South African schooling system, many English Additional Language (EAL) student nurses have poor English proficiency and struggle academically. There is a need to ensure that those selected for nurse-training are academically successful. Aim of the study The aim of this study was to determine if there was a relationship between English proficiency, determined by the matriculation English results, and first-year nursing academic results. Methodology A quantitative design was used, and comprised of two phases, namely a self-administered questionnaire and a correlation, retrospective record-review. The total population of first-year nurses was 271. The participating sample amounted to 133 consenting nurses, undertaking the R425 programme at KwaZulu-Natal College of Nursing campuses. Stratification sampling was used to ensure that approximately half the sample of nurses attended a rural campus and half attended an urban campus. Random sampling was then used to select the urban campuses and the rural campuses from where students were invited to participate. Descriptive and inferential statistical analysis as well as regression analysis was applied, using the SPSS version 20.0. Results Matriculation English appears to be positively related to many factors including the socio-economic situation when growing up, attending a rural primary school, library access at primary school and access to computers in primary and high school. English additional language nurses prefer to be taught nursing in English and consider it an advantage. The examination failure rate of first-year nurses was 24%. Nurses’ with higher matriculation English results on entry to nurse-training obtained better academic results in first-year nursing examinations. Recommendations Language should not be a barrier to admission into higher education, however a certain threshold of proficiency in the language of instruction is recommended. Under-resourced schools need to be addressed, especially in rural areas, including the language of instruction at schools. The matriculation results of the home language should also be considered in admission criteria to higher education. Policy formulation on formal academic support and language training, especially during the first-year of nurse-training is required for those struggling academically.

Dissertation in partial compliance with the requirements for a Master's Degree in Technology: Chiropractic, in the Department of Chiropractic, Durban University of Technology, 2010. / Background: Chiropractic in South Africa seems to be gaining acceptance by medicine with increased recognition from the private healthcare sector. This trend is reflected by the recognition of private healthcare providers of chiropractic services. Integration would accelerate the growth of the chiropractic profession in this country. It is therefore important to understand how chiropractic is currently perceived with respect to integration into the KwaZulu-Natal (KZN) healthcare system. As well as to determine factors perceived to facilitate or hinder this integration. Objectives: To explore and describe the perceptions of selected stakeholders about the integration of the chiropractic profession into the KZN healthcare system. Method: The sample included ten selected stakeholders within the KZN healthcare sector. Each participant participated in a semi-structured interview. Questions included participants‟ experience of chiropractic, the role and scope of chiropractic practice, and key developmental issues affecting integration. Interviews were captured on a digital voice recorder and transcribed into text. Data was analysed by the use of NVivo software (NVivo 8, developed and designed in Australia, copyright 2008 QSR International Pty Ltd. ABN 47 006 357 213). Results: The majority of participants (n = 7) had a positive experience of chiropractic, but few (n= 2) recognised the diagnostic role of chiropractic. All participants, except two doctors, believed that integrating chiropractic into the public healthcare system would benefit the healthcare fraternity, the chiropractic profession and patients. However, hindering factors perceived by the participants included: chiropractors practicing non-evidence based techniques; chiropractic being registered with a different council and being taught at a different institution to conventional medical professionals; and most importantly a lack of knowledge of the profession. Facilitating factors were III perceived to be: increased education of stakeholders about chiropractic; improved communication between chiropractors and medical doctors; improved marketing strategy; and lastly improved patient management. Conclusions: A positive experience of chiropractic is directly affected by a positive exposure to the profession. The profession itself is responsible for dispelling some of the confusion it has created, by collectively practicing evidence based medicine, and marketing a united message to stakeholders.

Submitted in fulfillment of the Masters Degree in Homoeopathy, Durban University of Technology, 2010. / Introduction All the studies on the perception of homoeopathy in South Africa conducted so far have found that the group least knowledgeable about homoeopathy is the African group. However, no study yet has focused on this group, and tried to find out more detail about their perceptions of homoeopathy. The study took place in Mnambithi, a town in the northern part of KwaZulu Natal within the Uthukela District with a population of about 200 000 people. Aim of the study The overall aim of this study was to determine the perception, knowledge and utilization of homoeopathy amongst African adults resident in Mnambithi, KwaZulu Natal. Methodology The survey method was employed to conduct this study. The research instrument was a self-administered questionnaire. The number of questionnaires completed was 1034, distributed according to suburbs 10.6%, centre of town iii 9.8%, former township areas 58.7% and rural areas 20.6% which approximately reflected the proportion of the population resident in those areas. The data was primarily analyzed by means of descriptive statistics using frequency tables. Results The sample consisted of 50.3% males and 49.5% females, with the largest group of respondents being 41 years old and above. Most were unemployed (61.8%). The educational standard was high, with 43.8% of respondents having matric and 20.4% having a diploma or degree. Most respondents (98.6%) had not heard of homoeopathy before. Only 0.1% of respondents had consulted a homoeopath before. 83.8% of respondents answered that they would consider consulting a homoeopath in the future, and 43.3% indicated they were interested in learning more about homoeopathy. The lack of knowledge about homoeopathy and yet being interested in learning more, is a similar finding to other perception studies. Conclusions It can be concluded from the results that the level of knowledge of homoeopathy amongst respondents was minimal, with only 10 out of 1034 respondents having heard of homoeopathy. Questions relating to the perception of homoeopathy were restricted to those who had heard of homoeopathy, but because of the small number, no conclusions regarding perception can be drawn.
