This master’s thesis describes the area of operational suitability data that is established as part of the aircraft type certificate. The thesis first chapters are describing OSD, its origin and implementation. The thesis also analyzes all regulations that are connected with this matter and are focusing on the training of maintenance certifying staff. A part of this thesis deals with the description of aircraft Evektor EV-55 Outback, for which is created the educational material, and a description of its fuel system. The concept of educational material for maintenance certifying staff theoretical type rating training and an example of final test are at the end of the thesis.

A thesis submitted in partial fulfilment of the requirements for the degree of Masters of Arts in Clinical Psychology at the University of Zululand, South Africa, 2011. / South Africa is at a critical point in the debate about the future of health-care in the occupation-specific dispensation (OSD). It also faces the exodus of valuable human resources that was perceived as greener pastures, as medical practitioners become increasingly dissatisfied with governmental policy, wage negotiations, work-place disillusionment, lack of service delivery, expressions of corruptions, and lack of resources. This research aimed to thematically analyse the experiences, opinions and feelings of medical practitioners in both the public and private health-care sectors as well as explored international trends with the intention of drawing comparisons, highlighting problem areas, and discussion of possible solutions. It was hoped that this research would contribute towards understanding the dynamics that marked the exodus of medical practitioners from South Africa, at a time when change in the health-care system was imminent. In order for the medical practitioners to remain in the current health-care system, a new dialogue would have been opened in which their concerns could be raised and evaluated.

Having a successful innovation process is crucial for any competitive enterprise. Being able to rapidly prototype and validate new concepts can reducethe time and cost from the specification-phase to a final product. This thesisinvestigates how open source hardware and software can accelerate the ideavalidation of proprietary systems.The development of a microcontroller shield and open-source-based softwareis described and how this artifact can take advantage of the open source community, thus making innovation more flexible and concept validation quicker.This thesis followed a five-stage development process, and is evaluated withtwo controlled experiments.The resulting artifact was shown through these controlled experiments thatit was able to improve the idea validation of proprietary systems. The resultof the controlled experiments showed that a new concept could be validatedfaster.

Magister Pharmaceuticae - MPharm / Prior to 2007, South Africa’s government became concerned about the loss and inability to retain certain professionals in its employment. Health human resources were distributed in favour of the private sector and urban areas while rural areas survived on a meagre portion of health employees. In 2007, the government introduced a re-designed remuneration structure for individual skilled professions namely, Occupation Specific Dispensation (OSD), with the goal to attract and retain professionals. This study qualitatively explores the perceptions of public sector employment (PSE) by pharmacists to extract how OSD-policy may or may not be succeeding. It also investigates the opinions of pharmacists on the promotional structure of OSD and opportunity for career advancement (CA) as a possible indication of organisational commitment. Participants were recruited from four career streams in OSD’s structure, all employed in the Department of Health, Provincial Government of the Western Cape. In the first stage of data collection, one-on-one interviews were conducted with key-informants which consisted of policy specialists (n=2) and management (n=2). In the second stage, focus group interviews were conducted comprising of production and supervisory pharmacists (n=27). Sampling strategies encompassed purposive, snowball and stratified sampling to ensure saturation of data and provide comparisons between groups and sub-groups. Thematic analysis of interview transcripts was performed using inductive coding in the first stage and apriori coding in the second stage. Themes and sub-themes were “reflexed” onto Human Resource and Work Motivation Theory by engaging a three question reflexive framework to ensure consistency in the interpretation of results. Eleven major themes emerged: overlapping of salary grades; variety of positions; being a manager of professionals; envisioning promotion; pay versus responsibility; pay equity and expectancy; OSD and attraction; OSD and retention; over-time and after-hours remuneration; interpreting OSD; and using unions to negotiate policy for professionals. 41 sub-themes that emerged were positively, negatively or neutrally connected to perceptions of PSE or CA. Positive sub-themes of PSE is that OSD has “ensured that entry level positions are extremely attractive” and OSD is “attracting more junior pharmacists to management positions”. Negative sub-themes of PSE include that a “retention strategy for experienced pharmacists tends to be neglected” and “some work related factors may nullify retention strategies”. Negative or stagnant perceptions of PSE produce an image that fails to care for individual employee needs and tarnishes the image of public sector employment. Positive sub-themes of CA are that OSD now “permits individual freedom of career path choice” and OSD “has created a variety positions through a broadened post structure”. Negative subthemes of CA are that “experienced pharmacists stagnate in their career” and “supervisors have a lot more responsibilities but get paid the same as production pharmacists”. Since the perception of career mobility is related to organizational commitment and retention, negative perceptions of career advancement may result in apprehension to develop via promotion or career path change. This can lead to employee boredom, complacency or frustration of career ambitions and eventual loss of staff. Some aspects of OSD, such as overlapping of salary grades, should be addressed by policy-developers to ensure the successful accomplishment of policy goals.

Yes / A study has been carried out to investigate controlled release performance of caplet shaped injection moulded (IM) amorphous solid dispersion (ASD) tablets based on the model drug AZD0837 and polyethylene oxide (PEO). The physical/chemical storage stability and release robustness of the IM tablets were characterized and compared to that of conventional extended release (ER) hydrophilic matrix tablets of the same raw materials and compositions manufactured via direct compression (DC). To gain an improved understanding of the release mechanisms, the dissolution of both the polymer and the drug were studied. Under conditions where the amount of dissolution media was limited, the controlled release ASD IM tablets demonstrated complete and synchronized release of both PEO and AZD0837 whereas the release of AZD0837 was found to be slower and incomplete from conventional direct compressed ER hydrophilic matrix tablets. Results clearly indicated that AZD0837 remained amorphous throughout the dissolution process and was maintained in a supersaturated state and hence kept stable with the aid of the polymeric carrier when released in a synchronized manner. In addition, it was found that the IM tablets were robust to variation in hydrodynamics of the environment and PEO molecular weight. / The research was funded by AstraZeneca, Sweden.

The purpose of the study was to explore the lived experiences of nurses on the implementation of occupational specific dispensation (OSD). Qualitative research using hermeneutic phenomenology was conducted in the three selected public hospitals in the Umgungundlovu district in KwaZulu-Natal (KZN). Data was collected by means of in-depth interviews with professional nurses, enrolled nurses and nursing assistants and focus group discussions with nurse managers purposively selected at the public hospitals in the Umgungundlovu district. Parse’s extraction synthesis analysis of data was done and seven (7) themes emerged from the participants’ dialogical conversation exploring the experiences of the implementation of OSD. The findings suggested that nurses viewed OSD as unfair labour practice because it divided nurses; there are those who grossly benefitted and those who benefitted less. The researcher concluded that the study will assist the authorities in the department of health both nationally and provincially to review OSD for nurses and close the gaps identified during the implementation as they were the pilot group. / Health Studies / M.A. (Health Studies)
