Awareness, knowledge and utilization of the human papillomavirus vaccine.

Allie, Naseera. January 2012 (has links)
OBJECTIVES To determine if health care workers are aware of the HPV vaccine and its availability, uptake of the vaccine and prescribing practices and reasons for non – uptake of the vaccine . METHODS Health care providers working in the private sector, in the Ethekweni health district in Kwazulu Natal, were interviewed. Health care workers included: 100 general practitioners, 50 gynaecologists, 50 paediatricians, 50 medical staff and 50 nursing staff. A questionnaire was designed for purpose of this study. Visits were be made to health care providers. All heath care providers who were willing to participate were interviewed. STATISTICS Comparisons of awareness among subgroups of health care providers was analysed using Chi-square tests. If significant, pairwise comparisons were made using a Bonferroni adjustment for multiple comparisons. Associations between awareness and other factors, such as demographic, uptake and beliefs were tested using a chi square test. Analysis was done by Stata v11 (StataCorp, 2009) i RESULTS Three hundred health care workers were interviewed - 50 gynecologists (16.7%), 52 pediatricians (17.3%), 99 general practitioners (33%), 49 other medical doctors (16.3%) and 50 (16.7%) nurses. Two hundred and sixty seven health care workers (89%) were aware of the HPV vaccine and one hundred and eighty eight health care workers (70.4%) informed patients of the availability of the HPV vaccine. Most (77.9%) practitioners have only prescribed the vaccine less than ten times. Gardasil® was prescribed by 46%, Cervarix® by 6.5% and prescription of either vaccine of health care workers was 50.2%. Practitioners were generally unaware that Gardasil® could be prescribed to males (62.9%). CONCLUSION Health care workers were aware of the HPV vaccine and prescribed the vaccine on request. However even though practitioners were aware of the vaccine, most have prescribed the vaccine less than ten times since licensing in 2008. Knowledge with regards to the licensed use of the HPV vaccines is deficient. / Thesis (M.Med.)-University of KwaZulu-Natal, Durban, 2012.

Spatio-temporal variations of the sedimentology and geochemistry of six estuaries within the eThekwini Municipality, KwaZulu-Natal, South Africa.

Pather, Keshia. 15 September 2014 (has links)
Estuaries are dynamic features of a coastline whose sediments are influenced by riverine and marine processes. Periodic events such as floods, as well as variations in mouth status, greatly affect the energy levels within an estuary and subsequently the amount of sediment erosion and deposition that takes place. Concurrently, pollutants are transported and deposited into estuaries and can reside in the sediments for many years. The estuaries of the eThekwini Municipality in KwaZulu-Natal, South Africa, are exposed to a variety of pollutants; however with the expanding industrial sector within this region, metal contamination is of concern. This study investigates the sedimentology and geochemical variations of six estuaries within the municipality namely, the uTongati, uMdloti, uMgeni, Isipingo and uMbokodweni estuaries as well as the Durban Harbour. To determine the spatial variations in estuarine sedimentology, sediment cores were collected longitudinal to the estuary axis. The core samples were analysed for sediment colour, texture and organic matter content. To assess the geochemical variations, core samples were analysed for Zn, Cu, Cr, Ni, Pb, As, Fe, Al, Ca, S, P, Mg, Mn, Cd and V concentrations. Some samples were also carbon dated to provide a temporal aspect to the sediment and geochemical variations. Descriptive and graphic techniques were used to examine the sedimentology within the estuaries; and the geochemical data was analysed with the use of multivariate statistics. Additionally, pollution indices and sediment quality guidelines were utilized to assess the pollution levels within the sediments. The results indicated that lower energy environments caused by protracted mouth closures in the uMdloti and Isipingo estuaries accounted for large amassing of fines. In contrast, the accumulation of mixed coarse and fine sediments in the uTongati and uMgeni estuaries was an indication of high fluvial flows and open mouth conditions. All carbon dated ages for all estuaries were greater than 700 years which may be attributed to a combination of scouring effects from past and recent flood events and also possibly due to the deposition of re-worked older sediments from upstream. Low metal concentrations were found within the sediments of all estuaries, and the presence of fines and organic matter governed their concentration variations with depth. The uMgeni and uMbokodweni estuaries which are located immediately downstream of industrial and urban areas, were found to contain relatively higher concentrations of elements Pb, Cu, As and Ni. These metals showed high enrichment within the sediments; however actual concentrations were below sediment quality guideline levels. General pollution levels within all estuaries were very low, and can be attributed to the climatic influences within this region which has a ‘cleansing’ effect on the estuarine environments in removing contaminants. / Thesis (M.Sc.)-University of KwaZulu-Natal, Durban, 2014.

The role of integrated development planning in the integration and transformation of former apartheid townships in South Africa : a case study of Inanda, Ntuzuma and KwaMashu (INK), eThekwini Municipality (Durban).

Mngadi, Thandekile. 24 October 2014 (has links)
During the Apartheid period township areas were excluded from development. Townships only contained residential land uses, and limited social services of poor quality. Such areas lacked economic activities people had to travel to the city for employment opportunities and access to better services. As a result of apartheid planning, the country was left with cities and towns that are racially divided, lack access to business and other services and have sprawling informal settlements and spread out residential areas that make cheap service delivery difficult. All the above mentioned outcomes require a new approach to address the development challenges in South Africa. This led to the formulation of Integrated development planning processes, which were adopted to contribute towards eradicating the legacy of the past by providing a framework for economic, social development, environment protection and to deal with spatial and infrastructure issues in all the municipal areas. This study presents findings on the extent in which integrated development planning initiative in eThekwini Municipality has transformed and integrated the Inanda, Ntuzuma and KwaMashu (INK) areas. Based on the findings of this research it has been revealed that integrated development planning approach has played a major role in transforming and integrating the INK area, hence there has been improvement in the social, economic and the spatial aspects of development. However it is recommended that the municipality also consider development of light industries and skills development initiatives to address social and economic issues that are a challenge for INK areas / M.T.R.P.

Results of the Chicago area transportation study, 1955-61 : planning for the minimum total cost transportation system for the year 1980

Wesselhoft, George J. January 1995 (has links)
The Chicago Area Transportation Study (CATS) set the standard for urban transportation planning during its original 1955-61 genesis years. This study examined CATS' planning methodology during these years and its 1962 regional transportation plan for the Chicago metropolis which had a planning target year of 1980. The subject focus of this study was on expressway planning while the temporal focus was from the late 1950's to circa 1980. The findings of this study revealed four key reasons why CATS' 1962 expressway plan was largely never implemented. These reasons include the inconsistency of some of CATS' 1962 projections for 1980 versus actual 1980 data, the apolitical orientation of CATS, increased urban environmentalism, and rising expressway infrastructure costs. Yet despite the lack of plan implementation, the literature supports the conclusion that CATS did set the standard, at least in its methodology or planning approach. / Department of Urban Planning

Human-urban radiation exchange simulation model

Park, Sookuk 28 April 2011 (has links)
The purpose of this study is to develop an improved human radiation exchange model for use by planners and researchers. Although applicable for all environments, emphasis will be on urban areas. All processes of radiation exchange between the human body surface and surrounding environments were investigated through human body area factors (effective radiation area factor, feff, and projected area factor, fp), existing human thermal exchange models and three-dimensional (3D) computer simulation models with collected microclimatic data. For new body area factors, a sample of standing contemporary Canadian adults in normal-weight (male: 31 persons, female: 40) and over-weight (male: 48, female: 20) body mass index (BMI) categories were analyzed. A 3D mean body model was created for each category. Only very small differences in feff and fp were found between genders and BMI categories. Differences in feff and fp values between this study and previous studies were very large, up to 0.101 and 0.173, respectively. Another common body posture, walking, was also studied for the normal-weight male and female BMI categories. 3D computer walking body models at four stride positions were created. The directionless fp values for walking posture had minor differences between genders and positions in a stride. However, the differences of mean directional fp values between azimuth angles were great enough (up to 0.072) to create important differences in modeled radiation receipt. When both standing and walking postures are considered, the mean feff value of standing (0.826) and walking (0.846), 0.836, could be used. However, fp values should be selected carefully because differences between directional and directionless fp values were large enough that they could influence the estimated level of human thermal sensation. A new human radiation exchange model was developed using the new body area factors and compared with five existing models and one method (Burt, COMFA, MENEX, OUT_SET* and RayMan models and the six-directional method) using collected microclimatic data observed in Guelph, Ontario, Canada. Most differences between models came from absorbed solar radiation, especially absorbed direct beam solar radiation because of differences in fp* (=fp×feff) and feff or some missing components (feff or view factors). The lowest differences between the new model and the RayMan model alter the net all-wave radiation estimate up to 29 Wm-2, which can be significant in the human thermal exchange model. For 3D computer estimation, a new human-urban radiation exchange simulation model was developed combining the new human radiation exchange model and improved urban area factors (i.e., albedos and view factors of sunny and shaded building, ground and vegetation surfaces). The results of the new computer model were compared with microclimatic data collected in Nanaimo, B.C., Canada and Changwon, Republic of Korea as well as with two other 3D computer simulation programs, RayMan Pro and ENVI-met 3.1. The differences between the collected data and the new model were very small. Their correlation was very strong, over 0.99 for total radiation. RayMan Pro and ENVI-met 3.1 programs had larger differences, and their correlations with measured data were weaker than the new model’s. Accurate meteorological and urban setting data should be obtained for better results. The new model will give planners and researchers a simple tool to estimate accurate radiation effects in complex urban areas. / Graduate

An assessment of management practices in Chinese family-owned SMEs in the Cape Metropolitan area.

Ping, Yu January 2004 (has links)
China is a country built on traditions and one of its most respected traditions is a preference for the family unit. The closeness of the family unit is carried over into the economic life of the country. Family members not only live together, but also work together in the fields or in enterprises. The advantage of this is that families have a guaranteed labour force that is not only loyal and can also be trusted. The disadvantage however is that positioning within the business is not always based on merit and competence, or trustworthiness which can ultimately impede growth. This research was an examination of Chinese family-owned businesses that focused on their management practices. The purpose of the study was to explore the management characteristics of Chinese family-owned businesses by means of interview data collected from five Chinese businesses in the Cape Metropolitan area. The emphasis of the project concentrated on the establishment, expansion and growth, ownership and leadership, management structure, the impact of cultural factors and the strategy for the future as well as challenges in terms of competitors and environments.

Ekofyziologické a morfologické rozdíly mezi domácími a invazními populacemi \kur{Lythrum salicaria} L. / Ecophysiological and morphological differences between native and invasive populations of \kur{Lythrum salicaria} L.

KAŠPAROVÁ, Františka January 2011 (has links)
Native to Europe and Asia, Lythrum salicaria is an invasive element on some other continents. Plants in the invaded areas are more robust, higher, and generally more successful compared to individuals in their original area. Based on my results these characteristics cannot be explained by neither higher photosynthesis, chlorophyll and carotenoid mass, nor specific leaf area.
