A partial validation of the WHOQOL-OLD in a sample of older people in South Africa / Lizanle van Biljon

Van Biljon, Lizanle January 2014 (has links)
This article describes the psychometric properties of the WHOQOL-OLD (an add-on module to the World Health Organization's Quality of Life measure for older people) in a South African sample. International literature cites three short versions of the WHOQOL-OLD instrument. The psychometric properties associated with these three short versions of the WHOQOL-OLD are also described. The unique challenges posed by ageing populations are evident in both developed and developing countries. In South Africa the elderly population is also increasing dramatically. There is a disproportionate distribution of older persons per ethnic group, with white older people representing the largest group of older South Africans (21%, proportional to ethnic group). Regardless of integration policies in post-apartheid South Africa, especially in terms of housing arrangements, the majority of long-term care facilities in South Africa remain to be occupied predominantly by white older people. For this reason the participants of this study were mostly older white South Africans. It is, however, projected that this picture will change in future times due to more aggressive transformation-driven policies. A national audit of residential care facilities by the Department of Social Development in 2010 indicated a need for psychosocial interventions since the QoL of residents was found to be undetermined. QoL research in South Africa has largely been conducted from socio-economic and health-care perspectives and has tended to focus on specific societies in which older people are usually not explicitly included. Evidence exists of various qualitative studies among older people living in long-term care facilities, from a psychological perspective. However, the short supply of quantitative studies in this setting is significant. The lack of measurements developed for an older population also resulted in an increasing need for the development of gerontological QoL measurements with sound psychometric properties. Internationally, various measures of QoL utilised in older age groups have become increasingly popular. This study took particular interest in the WHOQOL-OLD instrument. Under the auspices of the World Health Organization Quality of Life group, a collaborative effort among numerous researchers from various countries has led to the development of a measure focussing on the QoL in older population cohorts. The initial development of the generic WHOQOL measures of quality of life occurred in 15 different centres worldwide, excluding South Africa. In the development of an add-on module, 22 centres around the world were involved (again excluding South Africa). It cannot be assumed that measuring instruments developed in a Western context are applicable in an African context. South Africa is a very diverse nation - the majority of ethnic groups lead a collectivistic existence. As a result the determination of the psychometric properties of such instruments, for use within South Africa, was needed. It is of importance to note that the participants of this study were more individualistically inclined, which is comparable to Western societies. This study was the first step in exploring the instrument’s reliable use within South Africa. Surveys were completed by 176 older people who were fluent in both Afrikaans and English. Participants of the study resided in long-term care facilities in Potchefstroom in the North-West province of South Africa. Their ages varied between 61 and 95 and the mean age of participants was 77 years. Of the respondents, 50 were male and 126 were female. All reported average to good health and cognitive ability. The current study found encouraging results related to the original factor structure of the WHOQOL-OLD as well as the three shorter versions of this instrument. Results from the data of the current sample seem to fit the original structure model well. The reliabilities associated with the various sub-dimensions point to a reliable instrument. The original WHOQOL-OLD questionnaire with its 24 items or any of the three short versions of this instrument can therefore be utilised in a South African context. / MA (Clinical Psychology), North-West University, Potchefstroom Campus, 2015

Dysfunctional breathing : Clinical characteristics and treatment

Hagman, Carina January 2016 (has links)
Background: Dysfunctional breathing (DB) is a respiratory disorder involving an upper chest breathing pattern and respiratory symptoms that cannot be attributed to a medical diagnosis. Aim: The overall aim of this thesis was to describe patients with DB and investigate clinical outcomes after physiotherapy treatment. Methods: Study I was descriptive and comparative, that included 25 patients with DB and 25 age- and sex-matched patients with asthma. Health-related quality of life (HRQoL), anxiety, depression, sense of coherence, influence on daily life due to breathing problems, respiratory symptoms, emergency room visits and asthma medication were investigated. Study II, a 5-year follow-up study based on the same sample as study I (22 patients with DB, 23 patients with asthma), studied treatment outcomes after information and breathing retraining. Study III was descriptive and correlational (20 healthy subjects), investigating whether the Respiratory Movement Measuring Instrument (RMMI) can discriminate between different breathing patterns in varying body positions. Study III also studied correlations between respiratory movements and breathing volumes (12 healthy subjects). Study IV was a single-subject AB design with follow-ups. Self-registered patient-specific respiratory symptoms and respiratory-related activity limitations and breathing pattern (measured with the RMMI) were evaluated after an intervention consisting of information and breathing retraining in five patients with DB. Results: Patients with DB had lower HRQoL (SF-36): vitality (mean 47 vs. 62), social functioning (70 vs. 94) and role emotional (64 vs. 94) (p<0.05) than patients with asthma. The DB group had a higher prevalence of anxiety (56% vs. 24%) and experienced more breathing problems than the asthma group. Patients with DB had made several emergency room visits and had been treated with asthma medication. At the 5-year follow-up, patients with DB showed improved HRQoL (SF-36): physical function 77 to 87 (p=0.04), decreased breathing problems and emergency room visits, and they were not treated with asthma medication. The RMMI can differentiate between different breathing patterns in different body positions. Strong correlations between respiratory movements and breathing volumes were observed (rs 0.86-1.00). The results in study IV indicate that patients with DB benefit from information and breathing retraining regarding decreased respiratory symptoms and activity limitations and improved breathing pattern.

Study on dimensional measurements based on rotating wire probe and acoustic emission touch sensing

Elfurjani, Salah 18 August 2016 (has links)
There is an increasing trend towards miniaturization of micro features as well as micro parts. In order to accurately produce these components and the miniaturized features on them, accurate measurement of the component dimensions is required. However, there are limitations in the dimensional measurement of miniature components: micro-probes and Micro coordinate machines (micro-CMMs) suitable for micro-feature measurement are expensive and fragile so it can be difficult to justify the cost for dimensional verification of batch-produced parts (in many cases miniature components are batch-produced). Therefore, a new cost-effective way for dimensional measurement of miniature components is needed. With this in mind, this thesis describes the development of a novel, three-dimensional measurement system using a rotating wire as a probe and acoustic emissions for contact sensing. This study presents a novel concept of three-dimensional measurements using a rotating wire as a probe and acoustic emission for contact sensing. Experimental results show that the probing system can measure a part with high repeatability. A controller algorithm has been developed for automated scanning within a machine tool. The performance is verified against calibration artifacts. The main contributions of this thesis are as follows: firstly, the traditional contact and non-contact micro coordinate measuring machines including sensing techniques and acoustic emission sensing are reviewed, and a clear set of knowledge gaps are identified in these fields. Secondly, a novel concept of three-dimensional measurements using a rotating wire as a probe tip and acoustic emission for contact sensing is introduced. The operation and measurements of the rotating micro probing based on acoustic emission (AE) sensing are validated experimentally. Initially, the ability of the rotating microprobe tip based on AE sensing to counteract the measured surfaces interaction rubbing is investigated. Other areas of validation are in the determination of the probing point repeatability, the straightness, and probe tip calibration. Thirdly, the acoustic emission signal and its characterizations of the probe tip touches are studied. The behavior of the rotating probe tip focusses on the threshold, touching time and as well as measured materials type that has an effect on probing accuracy. Finally, the estimated effective diameter and approximation threshold are modeled. This work is directly aimed at ensuring that the developed rotating probe tip based on AE sensing is capable of operating in an industrial metrology environment. It is concluded that the developed rotating probe tip based on AE sensing will be able to address the current needs of the micro-CMM community. On the other hand, it is possible that the rotating wire probe tip based on AE sensing can measure micro holes less than the achieved in this work, further increasing its usefulness. / Graduate / elfurjan@uvic.ca

Determining customer satisfaction: a case study of a tourism establishment in the Vaal region

Cilliers, Charmaine Danielle January 2018 (has links)
M.Tech (Department of Tourism Management, Faculty of Human Sciences), Vaal University of Technology. / Tourism is an extremely important sector in any economy of a country and is a package of combined services and goods. There are a variety of types of tourism, and tourism also has a variety of sectors and characteristics. Customer satisfaction is very important within any organisation, because it provides a variety of benefits. The Kano model and many theories assist in understanding customer satisfaction and the factors that better influence the satisfaction of the customers. To accurately measure the satisfaction of customers, there are a variety of guidelines to follow to develop a well-developed questionnaire. The main goal of this study was to determine customer satisfaction and the factors that contribute to customer satisfaction, based on a case study at a tourism establishment (accommodation establishment) in the Vaal Region. The objectives were to conduct a literature review to identify the factors that affect customer satisfaction at an accommodation establishment and develop a measuring instrument to determine customer satisfaction at an accommodation establishment. Furthermore, an empirical analysis was conducted to measure the level of performance of the identified factors at an accommodation establishment in the Vaal Region. Additionally, to determine the factors that contribute to the satisfaction of the customers at a specific accommodation establishment in the Vaal Region. Thereafter, determine the difference between the factors that are regarded as important contributors to customer satisfaction and the factors with which customers are satisfied with at an accommodation establishment. Moreover, determine the difference between customer satisfaction factors across trip-related and demographic variables at an accommodation establishment. Finally, recommendations were made regarding the empirical results and for future research. The research followed a case study approach using quantitative, exploratory and descriptive research to administer and test the questionnaire, and to evaluate the satisfaction of the customers. Furthermore, the study used a non-probability method, convenience sampling. The sample size of the study was 132 customers at the accommodation establishment and a questionnaire was used to measure the satisfaction of the customers. The results indicated that the majority of the respondents were totally satisfied with certain aspects at the accommodation establishment. In total 11 factors were identified that contribute to customer satisfaction, and a total of 10 factors were identified that influence the satisfaction level of the customers. There was a statistical significant correlation between the factors with which customers are satisfied with, the factors that the customers regard as important, other trip-related and demographic variables. It can be seen that the accommodation establishment must take into account the factors which influence customer satisfaction to obtain higher customer satisfaction by.

A Study of the Selling Strategy of the Metrology-- Case Study of Coordinate Measuring Machine

Chen, Cheng-Tung 16 August 2011 (has links)
ABSTRACT(­^ ¤å ºK ­n) The mother of the industrial machinery industry, often regarded as a national benchmark assessment of industrial competitiveness, the traditional concept of the cutting and forming machine tools for the spindle, including optoelectronics, semiconductors, automobiles, 3C electronics and aerospace industries, the relevant production or processing equipment, all belong to this category. With the evolution of technology, increasingly stringent product quality requirements, such as the appearance of the size of the high precision requirements and the material surface, gradually the importance of testing equipment and manufacturing go hand in hand, on behalf of the state's technology industry is expected in the near The future will be an important assessment of industrial competitiveness indicators. On the other hand, the mainland market after ten years of cross-strait exchange, itself played a significant change, from the early to the extreme dependence on imported equipment to produce the world-famous cottage products, no matter how the people of Taiwan to the mainland products exclusion, in the free under the natural law of market competition, the consumer market in Taiwan has long been filled with many mainland-made products. Their number and variety of the broad, deep penetration, simply makes hard to detect, and many exclusive products in the mainland business executives, the factory uses a lot of their own system of equipment are still unaware of the mainland, and even know, but also not find to alternative products. Indeed, many products have to meet the continent needs, these needs is not only reflected in the consumer goods market, is also rapidly spreading to the industrial market. Most of the countries with advanced manufacturing technology in the world, more or less with metrology industry. Taiwan alone will not only have no metrology manufacturing base, and even the Taiwan metrology companies in , mainland China, the increasing decline in ability to survive, the market that introduced by the Taiwan factories in the past swallowed gradually and easily by the local vendors. Worry about the future of Taiwan metrology industry. If Taiwan metrology industry can not get a good position in the world, can we be famous just by create a brand? Case is a company with more than 30 years of metrology sales background, in southern Taiwan. Because the relatively small market, it is difficult to obtain the dominant position of advantage. However, with the rise in the mainland market, the case company is full of many opportunities. This paper will research the sale strategy during these changeable situations. Bisides, metrology includes wide range products, this paper choose Coordinate Measuring Machines (CMM) as the basis of the primary products, mainly because of higher prices, the level of broader considerations in business, relatively high barriers to entry, in addition, it also has many features quite representative of the industry's products. Key words: Metrology, Coordinate Measuring Machines, CMM, hardness, surface roughness measuring instrument, roundness measuring instrument, the contour profile instrument, caliper, height gauge, optical flatness gauge, indicating scale, micrometer , microscopes , projectors , block gauge
