M. Tech. (Department of Process Control and Computer System, Faculty of Engineering and Technology), Vaal University of Technology. / Personal health record system (PHRS) is a tool that is used in maintaining the health and wellness of an individual as well as helping with illness of an individual. PHRS gives the individual access to a wide range of credible health information, data, and knowledge. Individuals can use that access to improve their health and manage their diseases. Patients with chronic illness can track and manage their health in conjunction with their health provider, this will promote early intervention when they encounter an abnormality or complications. Continuous monitoring and storing of health information has been a challenge for patients and health providers. Personal health data monitoring and retrieval system for health providers was designed and implemented. The main aim of this study was to develop an accurate, secure and flexible personal health data monitoring and retrieval system for health providers (PHRS). This was achieved. The research showed that when a patient health information (Electrocardiogram (ECG) and temperature) was monitored, the heartbeat (ECG) sensor output the value as an analog value to the signal processing (NodeMCU) which was then converted to a digital value. The temperature sensor used in this research is a digital sensor which lowers the amount of ADC conversion that was done. The digital values are displayed on LCD, its send to a personal health data storage system which was designed for health information storage purposes. It also sends the value to a retrieval system which is an android application that is connected to the data storage system to display health information to the health providers from a remote location. Personal health data storage and the retrieval system are secure due to the Message queuing telemetry transport (MQTT) protocol used in the application layer. The MQTT protocol is secure due to the secure socket layer (SSL) which is an encryption based on presentation layer embedded inside the MQTT protocol. After the comparison of the software simulation and the prototype test, the differences in the value for the heartbeat and temperature sensor indicate 0.04 BPM and 0.04 oC which shows the accuracy of the sensing circuit. Personal health data monitoring and retrieval system developed is applicable and useful to multiple entities in and around South Africa such as; Ministry of health, hospitals, sport and recreations.

This study aims to explore politeness shown by lecturers during tuition and student support conversations with the objective of promoting polite interactions between IsiZulu mother tongue and non-mother tongue speakers in higher education in South Africa. In particular, the study investigates the way in which politeness in email communication influences learning outcomes within an ODL environment, using quantitative and qualitative research methodologies, a questionnaire as well as interviews to collect data from a cross-section of students from an Open Distance Learning (ODL) institution. All the results drawn from the data sources, namely the questionnaires and interviews, were enumerated according to the data collection tools used. Version 12 of SPSS and Nvivo were used to analyse the quantitative data. The analysis is also based on the politeness strategies of Brown and Levinson (1978) as well as a conceptual framework that links all the variables. Based on the results, the research hypotheses are accepted, thus indicating that politeness in email communication influences learning outcomes within an ODL environment. In particular, the results show that, overall, lecturers who employ politeness contribute positively to student compliance. Accordingly, the study recommends that ODL should recognise both the role of language in communication as well as the power and influence of politeness in communication. / African Languages / D.

This paper provides analysis of a series of email correspondences between secondary newcomer immigrant students and Latino business professionals within the same urban community. The author, using James Gee's discourse theory (1990, 1996, 1999, 2004) contends that school-based discourses and structures have historically operated as barriers to academic success and societal acceptance for the vast majority of secondary English Language Learners, indicating the systemic perpetuation of a racist, classist, xenophobic social order through the public schools. When an attempt is made to sidestep these school-based discourses and put students in direct contact with mature, successful practitioners of English outside of the education community, the students encounter "mentor talk," a set of discourses that uncritically embrace the notions of a neutral, meritocratic, knowledge-based socioeconomic order. At the same time, students encounter language that can be appropriated for their own creative constructions of identity as they seek to position themselves in a new society. Even when there exists a strong alignment between the student's socially-situated identity presentation and the ideological thrust of "mentor talk," many societal barriers stand in the pathway of social and educational advancement. More often, the student identities express resistance, often subtle, to the standard, hegemonizing guidelines for success they have been offered. / text

The aim of this research is to shed more light on an aspect identified as a gap in knowledge in the literature; the use of a social networking service as knowledge sharing platform. More specifically, this research sets out to establish if the social networking service Twitter could be used as knowledge-sharing platform in small South African businesses in the Western Cape. A mixed method research design is used. This includes gathering data through questionnaires as well as conducting semi-structured interviews for case study participants. The sample comprises 122 questionnaire participants together with 14 semi-structured interview participants across three small businesses located in the Western Cape Province. Although it is apparent from the study conducted that small businesses are not yet willing to forego traditional platforms such as Email to use Twitter exclusively as a knowledge sharing tool, the researcher proposes a case for using Twitter, which he believes, could take the most advantage of the functions Twitter brings to a small business operation. / School of Computing / M.

The use of cellphones has increased all over the world. That invites many academics to conduct research on the usage of these devices, especially by young people, since young people join Social Network Sites (Facebook, Mxit, 2go, Whatsapp) and use a shorthand language. Most studies are related to the use of English and other languages that are recognised by computer software. There are few studies, if any, that have been done in relation to the use of African Languages on these sites. This research therefore aims to seek to explore the use of African Languages, especially isiXhosa, in assessing how technology might help in language development through the usage of SNSs that learners already use to equip them with educational material in their mother tongue. This study was conducted in two high schools, Nogemane Senior Secondary School in a disadvantaged and remote rural community with limited access to additional educational material such as magazines, newspapers, and television. The school also lacks basic study materials such as textbooks from the Education Department and they have no access to a library and laboratory. They also only have very few subjects to choose from. Nombulelo Senior Secondary School is in Grahamstown. This school has good infrastructure and learners have access to different technological devices and they can access libraries. What is common between learners in both schools is that they are all doing isiXhosa as a first language and are using SNSs to interact with each other. This study has found that learners enjoy using SNSs rather than reading the printed books. Furthermore, they enjoy and prefer interacting in isiXhosa in their conversations. Learners also use the web to post and show their creative writing, regardless of the shorthand form writing they use on the SNSs. This study has found that learners are not well equipped with basic isiXhosa skills when reaching the FET phase. They lack the understanding of standard isiXhosa idioms and proverbs. That clearly means that they are equipped in the more modern forms of literature rather than the traditional oral forms. IsiXhosa teachers also see SNSs as the better platform to engage with learners and they suggest that there must be a section in the subjects at school that teaches about cyber bullying and being safe online. This thesis also presents examples of new and contemporary forms of SNS-speak that are used by learners in both the rural and urban schools. This study is more concerned with SNSs for literacy development and to assess whether the shorthand writing has negative or positive effects in writing isiXhosa. This is done against the backdrop of a literature review which explores new literacies, computer mediated communication, social identity models as well as language policy and planning.
