Referencing echocardiographic measurements for premature and low-birth weight infantsJacobs, Salomi January 2012 (has links)
Thesis (M. Tech. (Clinical Technology)) -- Central University of technology, Free State, 2012 / Introduction: Reference ranges for cardiac measurement are available for adults, children and term infants but the same cannot be said for preterm or small for gestational age (SGA) infants surviving as a result of modern intensive care units.
No published data of reference ranges for preterm infants exists for the South African population. Infants with congenital heart disease are twice as likely to be small for their gestational age and these reference ranges may affect clinical management decisions, therapeutic response and prognosis of these neonates. The aim was thus to establish reference ranges for cardiac dimensions and functional values for preterm and low birth weight infants for central South Africa and compare them with international standards.
Methods: A total of 290 infants of less than 34 weeks of age and weighing less than 2500g at birth were examined during a twelve month period by echocardiography during the first 0-28 days of life. The study assessed normative cardiac measurements divided in M-Mode, 2-D and functional measurement for these infants in 3 weight groups.
Exclusion criteria were applied to any condition affecting the size and functionality of the cardiac system. The following dimensions were measured: Standard M-Mode values for the left ventricle, 2D measurements of valve mitral and tricuspid orifices, as well as functional assessments including Shortening fraction (SF %), Ejection fraction (EF %), and Muscle performance Index (MPI)-index of the Left and Right ventricle. Measurements were done by the leading edge methodology following the ASE recommendations.
A longitudinal study was also done to examine changes in these indices over the first month- on day 14 and day 28 of life. Interobserver differences were calculated for the variability between measurements of a single scan- 25 babies were re-measured and produced good repeatability.
Results: 290 infants were included to produce Referance ranges of measurements (means and standard deviations) for 3 weight groups namely: <0.999g, 1000-1499g, and 1500g – 2500g.
The gestational age’s ranges between 26-38 weeks with a median of 31 weeks, gender distribution was almost equal with a slight female preponderance. Body surface area ranged from a minimum from 0.076 m² and a maximum of 0.184 m², the body weight ranged between a minimum of 690g and a maximum of 2500g with a median of 1360g.
Discussion: The left ventricular diastolic and systolic, interventricular septum, posterior wall, aortic and left atrium dimensions showed a proportionate increase in diameter with an increase in body weight There were no differences in cardiac dimensions between Small for Gestational age” (SGA) versus “Average for Gestational age” (AGA). Gender and race played no role in any functional measurements or with the cardiac sizes. Weight correlated well with BSA and the data suggest that weight only can be used to develop tables for clinical use.
Cardiac chambers increased with BSA and weight and functional measurements stayed the same throughout the weight groups. Systolic and global functions were remarkably similar and constant throughout weight categories. . The longitudinal study also confirmed that the values are applicable to all low birth weight infants up to 28 days of age.
Differences existed between some of the average South African infant’s cardiac chambers and international values. The Inter Ventricular Septum (IVS) and Posterior Wall (PW) measured thicker and the Left Atrium larger. This could be due to numerous factors that should be investigated further.
Conclusion: The study emphasized the profound effect of growth and weight gain on the cardiac structure and that population specific reference values should therefore be developed and used.

AN EVALUATION OF FACTORS RESTRICTING MIDDLE MANAGEMENT ADMINISTRATIVE PRACTICES IN A HIGHER EDUCATION INSTITUTION: A CASE STUDY OF THE CENTRAL UNIVERSITY OF TECHNOLOGY, FREE STATETaljard, Annemi January 2008 (has links)
Thesis(M. Ed.) - Central University of Technology, Free State, 2008. / The existence and survival of an individual and/or organization, such as a Higher Education Institution (HEI), have always depended on the ability of this individual or organization to control the environment in which it exists. This person or organization should overcome certain threats and obstacles that may cross its path by means of simple, pre-constructed plans. The situation must thus be managed in order to ensure the continuation of the person or organization.
In this study the focus is on the functional tasks of the middle management team in an HEI. Middle management is concerned with the near future and is therefore responsible for medium- and short-term planning, organizing functional areas, leading by means of departmental heads, and controlling the management activities of the middle managers’ own departments.
This study wants to identify factors in the different functional areas of middle management that could hamper the productivity of this area, and thus the institution as a whole.
A qualitative study, with questionnaires as data capturing tool, was employed. Various factors that may hamper proper functioning were identified in the study. Lack of intra- and inter-departmental communication, staff shortages due to the restructuring process, countless policies and procedures in place (to streamline the execution of duties) hamper more than assist staff members in the execution of their duties. It was found that the staff members seek a sense of security, as this will lead to improved productivity.

An investigation of the phytochemistry and biological activity of Asparagus laricinusFuku, Sandile. Lawrence. January 2014 (has links)
Thesis (D. Tech. (Biomedical Technology)) -- Central University of Technology, Free State, 2014 / Medicinal plants are part of indigenous people‟s cultural heritage, thus since ancient times treatment of various diseases using medicinal plants has been part of human culture. The value of medicinal plants to mankind has been very well proven. It is estimated that 70% to 80% of people worldwide rely mainly on traditional health care systems, especially on herbal medicines (Stanley and Luz, 2003). In many societies the medicinal properties of plants were discovered mostly through trial and error, but use was also influenced by the belief systems of the people involved and often became entangled with religious and mythical practices (Mathias et al., 1996). Besides that, medicinal plants are proving to be rich resources of constituents that can be used in drug development and synthesis. Medicinal plants have been a source of a wide variety of biologically active compounds for many centuries and have been used extensively as crude material or as pure compounds for treating various disease conditions. Between 1% and 10% of plants out of an estimated 250 000 to 500 000 species of plants on earth are used by humans (Boris, 1996).
2
Plants used for medicinal purposes contribute significantly to the development of
major medical drugs that are used today. Most common medicines have compounds
extracted from plants as their primary active ingredients and many have provided
blueprints for synthetic or partially synthesized drugs (Simpson and Ogorzaly, 2001).
There has been a major resurgence of interest in traditionally used medicinal plants,
with a number of international and local initiatives actively exploring the botanical
resources of southern Africa with the intention to screen indigenous plants for
pharmacologically active compounds (Gurib-Fakim et al., 2010; Rybicki et al., 2012).
South Africa is considered a “hot spot” for biodiversity and more than 22 000 plant
species occur within its boundaries. This represents 10% of the world‟s species,
although the land surface of South Africa is less than 1% of the earth‟s surface
(Coetzee et al., 1999).
Plants have also been used by man for various purposes, among others as arrow
and dart poisons for hunting, poisons for murder, hallucinogens used for ritualistic
purposes, stimulants for endurance and hunger suppression, as well as medicine
(Duke et al., 2008; Cragg and Newman, 2005).
A derivative of the polyhydroxy diterpenoid ingenol isolated from the sap of
Euphorbia peplus (known as “petty spurge” in England or “radium weed” in
Australia), which is a potential chemotherapeutic agent for skin cancer, is currently
under clinical development by Peplin Biotech for the topical treatment of certain skin
cancers (Kedei et al., 2004; Ogbourne et al., 2004). Combretastatin A-4 phosphate,
3
a stilbene derivative from the South African bush willow, Combretum caffrum, acts as
an anti-angiogenic agent causing vascular shutdowns in tumors (Newman et al.,
2005; Holwell et al., 2002).
Further reliance on plants for drug development is demonstrated by the use of
galantamine hydrobromide, an alkaloid obtained from the plant Galanthus nivalis
used traditionally in Turkey and Bulgaria for the treatment of Alzheimer‟s disease
(Howes et al., 2003; Heinrich and Teoh, 2004).
The plant chemicals used for the above-mentioned purposes are secondary
metabolites, which are derived biosynthetically from plant primary metabolites (e.g.
carbohydrates, amino acids and lipids). Secondary metabolites are organic
compounds that are exclusively produced by plants and that are not directly involved
in the normal growth, development and reproduction of a plant (Firn and Jones,
2003). Yet, they have many functions that are important for the plant‟s long-term
health and appearance.
Plants, being stationary, have to cope with a number of challenges, including
engineering their own pollination and seed dispersal, local variation in the supply of
the simple nutrients that they require to synthesize their food and the coexistence of
herbivores and pathogens in their immediate environment. Plants have therefore
evolved secondary biochemical pathways that allow them to synthesize a spectrum
of organic molecules, often in response to specific environmental stimuli, such as
herbivore-induced damage, pathogen attacks, or nutrient deprivation (Reymond et
al., 2000; Hermsmeier et al., 2001).
4
The biosynthesis of secondary metabolites is derived from the fundamental
processes of photosynthesis, glycolysis and the Krebs cycle to afford biosynthetic
intermediates which, ultimately, result in the formation of secondary metabolites also
known as natural products (Dewick, 2002).
It is hypothesized that secondary metabolism utilizes amino acids and the acetate
and shikimate pathways to produce “shunt metabolites” (intermediates) that have
adopted an alternate biosynthetic route, leading to the biosynthesis of secondary
metabolites (Sarker et al., 2006).
Modifications in the biosynthetic pathways that produce secondary metabolites are
probably due to natural causes (e.g. viruses or environmental changes) or unnatural
causes (e.g. chemical or radiation processes) in an effort to adapt or provide
longevity for the plant (Sarker et al., 2006). Plants‟ secondary metabolites can be
classified into several groups according to their chemical classes, such alkaloids,
terpenoids and phenolics (Harbone, 1984; Wink, 2003).

Detecting Internet visual plagiarism in higher education photography with Google™ Search by Image : proposed upload methods and system evaluationVan Heerden, Leanri. January 2014 (has links)
Thesis (M. Tech. (Design and Studio Art)) - Central University of Technology, Free State, 2014 / The Information Age has presented those in the discipline of photography with very many advantages. Digital photographers enjoy all the perquisites of convenience while still producing high-quality images. Lecturers find themselves the authorities of increasingly archaic knowledge in a perpetual race to keep up with technology. When inspiration becomes imitation and visual plagiarism occurs, lecturers may find themselves at a loss for taking action as content-based image retrieval systems, like Google™ Search by Image (SBI), have not yet been systematically tested for the detection of visual plagiarism. Currently there exists no efficacious method available to photography lecturers in higher education for detecting visual plagiarism. As such, the aim of this study is to ascertain the most effective uploading methods and precision of the Google™ SBI system which lecturers can use to establish a systematic workflow that will combat visual plagiarism in photography programmes. Images were selected from the Google™ Images database by means of random sampling and uploaded to Google™ SBI to determine if the system can match the images to their Internet source. Each of the images received a black and white conversion, a contrast adjustment and a hue shift to ascertain whether the system can also match altered images. Composite images were compiled to establish whether the system can detect images from the salient feature. Results were recorded and the precision values calculated to determine the system’s success rate and accuracy. The results were favourable and 93.25% of the adjusted images retrieved results with a precision value of 0.96. The composite images had a success rate of 80% when uploaded intact with no dissections and a perfect precision value of 1.00. Google™ SBI can successfully be used by the photography lecturer as a functional visual plagiarism detection system to match images unethically appropriated by students from the Internet.

DEVELOPING AN INTEGRATED HUMAN RESOURCE DEVELOPMENT PLAN FOR OFFICE-BASED EDUCATORS IN THE FREE STATE PROVICEKgati, Edward. Mokoakoa. January 2013 (has links)
Thesis (PhD. (Education )) - Central University of Technology, Free State, 2013 / Human Resource Development is receiving increased attention as organizations seek performance gains from their workforces during challenging economic times, as well as a measure of compliance with the Skills Development Levies Acts (1998 & 1999) and the subsequent National Skills Development Strategy (NSDS). Organisations are facing increasing pressure to demonstrate how well they perform and to provide plans for their future improvement. The Free State Department of Basic Education (FSDoBE) is one public sector organisation which has embarked on aligning its human resource development strategies with the current developments as they present themselves in the labour market and as per NSDS requirements. In this research study, the construct of an integrated human resource development plan is challenged mainly along two lines: how office-based educators’ training needs assist to determine the model of an integrated HRD plan; and how the impact of the developed integrated HRD plan will assist with the heightened job performance of office-based educators. The effectiveness of job performance by office-based educators will consequently serve as a route to improved learner results in schools.
The delivery of quality education and training is one of the most important endeavours for the restoration of the culture of teaching and learning. The human resource development of office-based educators is therefore seen as an essential part for promoting the delivery of education and improving learners’ performance in schools. An essential part of developing an integrated HRD plan for office-based educators is typically with performance management process, which is the tool the FSDoBE has to use to meet its overall goals, and is directly dependent upon the ability of office-based educators to perform effectively in the management and delivery of services to schools.
In order to successfully develop an integrated HRD plan, the literature overview on human resource development and performance management was presented.
xvii
Human resource development plans have been studied and implemented in various organizations, but not adequately explored in the FSDoBE to surface possible specific performance challenges.
This study addresses this performance gaps by introducing an integrated HRD plan from the perspectives of various job ranks of office-based educators. It identifies gaps in the perceptions of office-based educators concerning performance management as conducted through the appraisal tool for office-based educators, the Performance Management and Development system (PMDS), and identifies steps in the development of an integrated HRD plan, concluding with lessons for practice. The data gathered through the literature study, questionnaires and interviews assisted the researcher to analyse and interpret the data and come up with the findings and conclude on the model of an integrated HRD plan for office-based educators. The questionnaires were administered to 60 office-based educators across their ranks (SESs, DCESs and CESs) and all 60 questionnaires were returned. The questionnaires and interviews were administered in the three education districts. The interviews were conducted to supplement the questionnaire data in order to gather rich responses from the participants. The data from corresponding questionnaire questions and interview questions was grouped together to correspond with the key research questions so as to provide the rich data as required by the research study. The key findings were that office-based educators have the desire to play a significant role in their job performance and that they need empowerment, resources and leadership to guide them in their daily duties. The analysis and interpretation of the data gathered further assisted the researcher to develop an integrated HRD plan as presented in Table 7.1 and as stated by the title of this research.
The evidence of the narrative incidents with office-based educators suggest that the development of an integrated HRD plan will provide a useful research tool for those wishing to study the design and use of HRD plans in the future, as it gives a
xviii
holistic overview to be taken in the process and makes the development of an integrated plan a feasible task for the researcher.
According to the model of the proposed integrated HRD plan, it requires a new way of thinking and interacting amongst district sections, and it should be regarded as a step forward to improved office-based educators’ development and subsequent influence on school-based educators’ knowledge and skills, and for improved learner performance in the schools.

The development of sensory products to stimulate children with learning problems (LP)Burger, Yolandi 11 1900 (has links)
Thesis (M. Tech.) - Central University of Technology, Free State, 2009 / Children with Learning Problems (LP) are mostly identified in the primary grades. Early intervention is desirable to remediate LP. One strategy is to use visual aids as a cue during an intervention strategy. A visual aid can be tactile and can appeal to the child’s senses, such as hearing and touch. Three main cornerstones which influence Sensory Product Development (SPD) were identified. These are design factors such as illustrations, colour, and book themes, the senses of the children and supporting factors which include therapeutic practices and cultural sensitivity. It is envisaged that if these three cornerstones are integrated into a sensory product such as a book, that it will be able to stimulate a child with LP through play, touch and sound. The aim of the study is the development of a qualitative tool that can be used to asses sensory products and the development of a sensory product that are tested for the specific target group. The sensory product was designed according to the guidelines that were identified in a literature review. This qualitative tool includes the various cornerstones and serves as a checklist that teachers and therapists can use to evaluate a sensory product to establish its suitability for a child with LP. The second article in this study recorded the responses from children with LP towards the sensory product and recommendations for the improvement of the sensory product.

A framework to position the somatology profession in South AfricaVosloo, Marlé. January 1900 (has links)
Thesis (M. Tech.) -- Central University of Technology, Free State, [2009] / Somatologists in South Africa no longer only practice beauty technology. They receive highly skilled training in the well being of the whole body, thus a more holistic approach is emphasized. Currently, stakeholders in the field of somatology are facing a number of challenges, which could impact greatly on the profession. The question of recurriculation, in order to align the training provided for somatologists with the new Higher Education Qualification Framework (HEQF) and the possible registration of the profession with a statutory body, are some of the challenges posed to the profession. In order to position the somatology profession favourably in South Africa, it was thus necessary to explore the current status of the profession through input from all stakeholders in the industry and to develop a possible framework. The objective of the study was firstly to obtain quantitative information from stakeholders in the field of somatology on matters related to their professional training, employment, recurriculation, referral trends to and from medical professionals and registration of the profession. Secondly, to obtain quantitative information from other medical professionals regarding referrals to somatologists and thirdly, to develop a possible framework that could facilitate the positioning of somatology more favourably as a profession in South Africa. Data were collected by means of two separate questionnaires, one sent to stakeholders in the somatology field and the other to medical professionals specializing in the fields of dermatology, plastic surgery and oncology. The results indicated that the stakeholders in the somatology field were satisfied with the current training provided by registered IX private providers and Universities of Technology. Job satisfaction was experienced by most, however, the hours and days worked could be improved. The need for short courses, as a means of staying in touch with the latest developments in the somatology industry, was identified. Currently, there exists a referral trend between somatologists and medical professionals, however, the frequency of referrals could be improved. The need for the somatology profession to register with a statutory body was identified by both somatologists and medical professionals. Two possible frameworks, with regards to the training provided for somatologists and the registration of the profession, were compiled based on the feedback obtained in the study, in order to position the profession somatology more favourably in South Africa.

Waste handling practices in the South African high-throughput poultry abattoirsMolapo, Ntahli Ashley January 2009 (has links)
Thesis (M. Tech.) - Central University of Technology, Free State, 2009 / The production of poultry meat at abattoirs implies a tremendous amount of organic matter that requires environmentally and biologically safe disposal or utilisation. As a result, waste management is a concern in poultry abattoirs worldwide. Problems with proper storage, handling, management and utilisation of by-products have come to the forefront in planning, establishing and operating of poultry abattoirs.
The rationale for this study centres on the need for the review of poultry abattoir waste management practices, by-product production and environmental implication at South African high-throughput abattoirs. The need for this review stems from the rapid growth of the poultry industry over the past ten years. The industry has responded to this growing demand with larger and faster processing lines and more employees. This has led to the generation of high loads of waste material associated with negative environmental impacts. Poultry waste is of great concern as it plays a major role in environmental affairs over and above the present crisis with waste in South Africa, especially in rural and peri-urban areas.
The primary objectives of the study were to identify the existing waste management practices in relation to the sources, type of waste material generated, and the methods of handling (collection, storage and disposal) as well as to ascertain whether there is any in-house treatment methods practised. In addition, to identify any environmental impacts resulting from waste management practices.
To obtain data, site visits were conducted countrywide and abattoir personnel were interviewed through a questionnaire, in detail about the operation and waste management practices of their respective abattoirs. Their experiences in the industry regarding waste management were determined as well. From a total of thirty-four registered and operating high-throughput poultry abattoirs, twenty-six (76.4%) were visited.
Huge amounts of wastes are generated at South Africa high-throughput poultry abattoirs, and these amongst others includes blood, feathers, feet, intestines, trimmed meat off-cuts, faecal matter, condemned chickens and waste-water. Waste handling practices varies according to abattoir preferences. Different collection facilities are used for different types of waste, 50 - 750_ containers and blood troughs are used for blood (table 4.5), crates, wheelie bins, conveyors, black rubbish bags for feathers (table 4.6).
Waste is either stored at the dirty area of the abattoir or in an open space next to the abattoir under strict supervision prior to disposal or by-product processing. Since not all abattoirs dispose off generated waste, some abattoirs have by-products processing facilities either on site or outside abattoir premises. Examples of by-products produced (table 4.3) include poultry (carcass) meal, feather meal, poultry oil and blood meal. Disposal methods used differs from burial, rendering, land application, municipal landfill, collection by farmers (animal feeding), burning, composting depending on waste type. It should however be noted that some of disposal method used are not legally approved in South Africa although legally permitted in other international countries as per literature review.
Three environmental implications were identified by the respondents included in the study (table 4.14) and these included air pollution, water pollution and land/soil pollution.
Recommendations are made to encourage the safe disposal of abattoir waste, minimisation of environmental implications and to limit the methods of disposal to those that are internationally permitted and suggested.

Problems encountered with the teaching of computer applications technology and information technology at senior secondary school level : a managerial approachRijuan, Li January 2009 (has links)
Thesis (M. Tech.) -- Central University of Technology, Free State, 2010 / The aim of the study was to determine the problems encountered by educators who teach Computer Applications Technology (CAT) and Information Technology (IT) in the FET band in the Bloemfontein area, Free State. The main contribution of the study lies in the identification of those problems. By knowing and understanding the problems, the Department of Education and the stakeholders will seek solutions to rectify the problems which will lead to the successful implementation of IT and CAT.
The assumptions of the study were that many educators lacked basic ICT skills and pedagogical training, and there were not enough computer stations for learners.
Both the qualitative and quantitative approaches were used in the study. The researcher used the survey research method and data was collected through the use of questionnaires and interviews. Simple random sampling was used to ensure that each member of the population in the study had an equal chance of being selected.
Descriptive and inferential statistics were used in analyzing the data from the questionnaires. In order to analyze the qualitative data from the interviews, the researcher described the sample populations, ordered and coded the data (data processing), and displayed summaries of data in such a way that interpretation became easy. This was done by preparing tables, diagrams and pie charts.
According to the results of the study, the problems that the educators encountered include a lack of sufficient didactical training for educators, learners don’t have computers at home to practice on, a lack of financial support to provide relevant facilities for schools, such as computer laboratories and learning materials in IT/CAT, educators spend too much time on paper work and do not have enough time for teaching, and IT/CAT teachers become ‘do-it-all’ teachers with regard to any work on the computer, such as fixing the computer, designing the school website.
Regarding the identified problems, recommendations were made, such as the Department of Education must review the curriculum of IT and CAT, sufficient subject related training and didactical training for IT and CAT educators should be provided by the Department of Education on a regular basis.
