The advances in communication technologies have resulted in a significant shift in the workplace culture. Mobile computing devices are increasingly becoming an integral part of workplace culture. Mobility has several advantages to the organisation, one such example is the “always online” workforce resulting in increased productivity hours. As a result, organisations are increasingly providing mobile computing devices to the workforce to enable remote productivity at the organisations cost. A challenge associated with mobility is that these devices are likely to connect to a variety of networks, some which may insecure, and because of their smaller form factor and perceived value, are vulnerable to loss and theft amongst other information security challenges. Increased mobility has far reaching benefits for remote and rural communities, particularly in the healthcare domain where health workers are able to provide services to previously inaccessible populations. The adverse economic and infrastructure environment means institution provided devices make up the bulk of the mobile computing devices, and taking away the ownership, the usage patterns and the susceptibility of information to adversity are similar. It is for this reason that this study focuses on information security on institution provided devices in a rural healthcare setting. This study falls into the design science paradigm and is guided by the principles of design science proposed by Hevner et al. The research process incorporates literature reviews focusing on health information systems security and identifying theoretical constructs that support the low-resource based secure deployment of health information technologies. Thereafter, the artifact is developed and evaluated through an implementation case study and expert reviews. The outcomes from the feedback are integrated into the framework.

This treatise investigates how information technology (I.T.) enables growth in a family business (the firm) in Port Elizabeth. The firm operates in the mobile telecommunications sector. The objective of the study is to gain a deeper understanding on why family businesses adopt information technology in their firm by means of a case study. The firm found its technology (or lack thereof) completely out-dated compared to the competition and customer demands. The future of the firm was in jeopardy. The study starts with a literature review of the following three topics which form part of the scope of the research: 1. Family businesses; 2. Influence of I.T. as a driver of growth in business; and 3. An introduction into the mobile telecommunications industry. Data are collected through structured interviews with family members involved in the business. The data are consequently linked to the theory and provides insight as to what the drivers are for I.T. adoption and the required core competencies or critical success factors of the firm. Although it might seem trivial for a small family business to adopt information technology, the research concludes that I.T. is critical for continuous growth and survival of this family business. Conversely due to a lack of internal skills the firm is heavily reliant upon outside consultants for advice, implementation and support. Recommendations which are of particular interest to family businesses in a similar environment are: • Embrace technology early, utilise I.T. solutions to grow and enhance current competitive advantage, do not see I.T. as a competitive advantage alone (Pavlou & Sawy, 2006); • If information expertise is not present within the company it is advisable to invest in that expertise through recruitment, training, partnership, or outsourcing; • Ensure software meets specification / is effective enough – this can be achieved by frequent releases cycles with small changes instead of infrequent release cycles with many big changes; • Engage the consultants in a partnership by i.e. providing a profit share – this will ensure that the consultants are committed to the cause and will also ensure that their involvement is also in their own best interest; • Choose local consultants who are easily accessible – build relationships and focus on trust; • Create lock-in (Amit & Zott, 2001), provide tools free-ofcharge for customers, this will make switching to competitor more difficult; • Automate as much as possible, enable standard work practices, routinize; • Be ready to adjust the organisational structure or relinquish control (Bruquea & Moyanob, 2007)

Thesis (Master of Engineering in Electrical Engineering)--Cape Peninsula University of Technology, 2018.<br>This research investigates and presents selected issues and aspects related to the railway mobile network (GSM-R) analysis and its shortcomings. Research studies show that millions of South Africans commuters are dependent on trains for daily movement activities, which significate contribute towards economic growth. Over the two decades, the exponential growth in wireless broadband service indicates the need for GSM-R improvement so that it can support the modern IP based protocol. The principle of implementing the digital network in railway already demonstrated significate improvement in the railway environment, especially in communication and signalling. Train traffic and train communications are the most critical aspects of railway scenarios due to safety and reliability. Both features form fundamental content to this research thesis. The exponential increase in Internet protocol (IP) based services and higher bandwidth requirements in modern technology applications have pushed the current Global system mobile for railway (GSM-R) technology to its maximum capacity as such the (GSM-R) platform is going to obsolete soon. There is a great need for the development of improved IP based networks for the future of the next generation network for fast smart trains to meet desired higher data low latency while improving quality of service (QoS). The focus of the research study is on modelling of an effective sharing method between public LTE and LTE-R without addition mobile infrastructure by utilizing train access unit (TAU), the main purpose is for public network (LTE) to handle railway emergency service including drop calls to improve quality of service (QoS). The second focus is an improvement of signal reception by spreading signals over wide spectrum range by utilizing Orthogonal variable spreading factor (OVSF) technique where LTE-R is not deployed as noted that this technique is deployed in the 3G network. The proposed scheme has adopted features in modern evolution communication and both scenarios were investigated modelled and simulated with comparison results showing better improvement in proposed conditions, there are many challenges in high-speed railway such as handover procedure and Doppler shift due to the velocity of the moving train.LTE-R has provided many solutions such as seamless handover, capacity availability as well as enhanced performance in both uplink and downlink. Digital evolution for railway GSM-R has been deployed in most developed countries in Europe and also expanded into Africa, there is a greater need for the seamless network to be developed due to an increased number of packet based services. Urban rail is the backbone of public transport in South Africa which is the Passenger Rail Agency of South Africa (PRASA). PRASA, and is the parent operator. Currently, PRASA has implemented digital railway network (GSM-R) to meet a high standard in railway. Modem demand and challenges require a cost-effective system to support IP orientated systems due to an increased number of packet-based services in the railway sectors.

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.

This dissertation examines the meanings that young adults give to their mobile phones in the township of Hooggenoeg in Grahamstown in the Eastern Cape. The research was predominantly conducted through individual interviews with nine young adults as well as two small gender-based focus groups. Participant observation as well as a close reading of the popular mobile website Outoilet also contributed to the study. Drawing on Silverstone, Hirsch and Morley’s (1992) work into the meanings attributed to the mobile phone through the domestication processes of appropriation, objectification, incorporation and conversion, the study argues for the heterogeneous roles defined for mobile phones as they are integrated into different cultural contexts. The term ‘raw phones’ in the thesis title refers to a particular cultural understanding of respectability in mainly working-class ‘coloured’¹ communities in South Africa, as described by Salo (2007) and Ross (2010), in which race, class and gender converge in the construction of the respectable person’s opposite – a lascivious, almost certainly female, dependent, black and primitive ‘raw’ Other. The study argues that in Hooggenoeg, the mobile phone becomes part of semantic processes that define both respectability and ‘rawness’ , thus helping to reproduce social relations in this community along lines of race, class and gender. A major focus of the study is the instant messaging application MXit, and how it assists in the social production of space, by helping to constitute both private and dispersed network spaces of virtual communication, in a setting where social life is otherwise very public, and social networks outside of cyberspace are densely contiguous and localised. In contrast, gossip mobile website Outoilet seems to intensify this contiguous experience of space. My findings contest generalised claims, predominantly from the developed world, which assert that the mobile phone promotes mobility and an individualised society, and show that in particular contexts it may in fact promote immobility and create a collective sociability.

Submitted in fulfillment of the requirements of the Master of Technology Degree in Information Technology, Durban University of Technology, Durban, South Africa, 2014.<br>This dissertation reports on handover in downlink Long Term Evolution (LTE) networks. The LTE is seen as the technology that will bring about Fourth Generation (4G) mobile broadband experience. The necessity to maintain quality of service for delay sensitive data services and applications used by mobile users makes mobility and handover between base stations in the downlink LTE very critical. Unfortunately, several handover schemes in LTE are based on Reference Symbols Received Power (RSRP) which include measurement error due to limited symbols in downlink packets. However, prompt and precise handover decision cannot be based on inaccurate measurement. Therefore, the downlink LTE intra-system handover is studied with focus on user measurement report. The study centers on preparation stage of the LTE handover procedure. Two different types of physical layer filtering technique namely linear averaging and local averaging are focused upon among others investigated. The performance of LTE conventional physical layer filtering technique, linear filtering, is compared with an alternative technique called local averaging. The output of each physical layer filtering is then used for LTE standardized radio resource layer filtering (otherwise called L3 filtering). The analysis of results from handover decision is based on simulations performed in an LTE system-level simulator. The performance metrics for the results are evaluated in terms of overall system and mobility-related performance. The system performance is based on spectral efficiency and throughput while mobility-related performance is based on handover failure. The performance comparison of the results shows that local averaging technique provides improved system performance of about 51.2 % for spectral efficiency and 42.8% cell-edge throughput for high speed users. Local averaging also produces a reduction of about 26.95% in average number of handover failure when L 3 filtering is applied for low speed mobile terminal. This result confirms that both averaging techniques are suitable for LTE network. Moreover, in the case of high mobility local averaging tends to be better than linear averaging.

Communication amongst field devices, control unit and programming unit in industrial automation networks is essential for bulk production, but largely consists of wired networks that can sometimes be bulky and substantially lack mobility as at times there can arise a need for a field device to be moved either for maintenance purposes or for rearrangement. There was therefore a need for wireless communication and PROFIBUS networks that can provide the minimum movement to field devices or the programing computer. Although wireless communication technology has penetrated the commercial network, it is still inadequately utilised in industrial settings due to electromagnetic induction and other forms of interferences due to industrial machinery. This dissertation introduced wireless communication in a PROFIBUS network where the MPI section was replaced with the wireless link. The PROFIBUS network technology is a hybrid of protocols where the PROFIBUS DP employs RS485 technology with a transmission rate of 45 kbps and above while the PROFIBUS PA employs Manchester Encoded Bus Powered (MBP) technology at a fixed rate of 31.25 kbps. In RS485 technology, data is transmitted as a voltage difference between the two wires while in MBP data is transmitted as transitions in current signal and data and power are transmitted on the same conductors. The PROFIBUS data is also transmitted in the form of telegrams which further puts a strain on any form of intermediate processing and hence the need for high speed processing. In this research task the PROFIBUS PA level transmitter measures the pressure of the fluid in the Blend Chest and sends it to the PLC. The level transmitter was installed and wired to the PROFIBUS DP/PA coupler. The PROFIBUS network, consisting of the PLC, variable speed drives, variable speed pumps, delivery pump and level transmitter, was configured and commissioned for controlling and monitoring from the programing computer. The program for the PLC was written using Siemens Step-7, compiled and downloaded to the PLC. The control and monitoring was done using the variable table. The wireless communication channel was then simulated using Matlab and Simulink. The wireless devices were then integrated into the PROFIBUS network and the MPI cable linking the programing computer and the PLC was then replaced by the wireless channel and the network was controlled and monitored from the programing computer over the wireless channel. On successful completion of this research task the research plant at MUT was controlled and monitored from the programing computer over the wireless channel and the researchers and demonstrators can now access the PLC and the PROFIBUS network using the wireless communication.<br>Electrical Engineering<br>M.

Submitted in fulfillment of the requirements for the degree of Master of Technology: Information Technology, Durban University of Technology, Durban, South Africa, 2015.<br>The use of mobile devices such as cell phones, smartphones, personal digital assistants and tablet computers is becoming prevalent in today’s world; and it is facilitating access to a vast amount of data, services and applications for the improvement of people’s lives. Advances in electronics and manufacturing technologies usually lead to the rapid release of newer and sleeker models with new features and capabilities. These newer models therefore render older models obsolete, and this pushes people to frequently replace their devices. The drawback of such frequent replacements is that a large number of devices are disposed and they end up as e-waste. The fact that e-waste constitutes a major hazard to human health and to the environment is the motivation behind this study whose aim is to examine the factors affecting the perceptions of teachers on the durability of cell phones in the e-learning context. This research aims was achieved through the content analysis of existing literature and through a survey of 67 secondary school teachers from the iLembe and UMgungundlovu district municipalities in the KwaZulu-Natal province of South Africa. The attribution theory was selected as the theoretical framework for this study, and it led to the identification of four independent variables (Demographics, Intention, Knowledge, and Actual use) and of one dependent variable (Perceived Durability). The results of this study indicate that teaching experience and school location are the only two demographics that affect other variables from this research: School location affects cell phone durability, and teaching experience affects cell phone usage intentions. These results also indicate that all the variables of this research are linked except for the relationship between knowledge and perceived durability. One of the recommendations of this study is the proposal of a three year cycle for cell phone renewals in schools mobile learning projects in order to manage e-waste through e-recycling, and this recommendation is based on the finding of this research that teachers believe that cell phones generally lasts between two to three years. The main contribution of this study is to have examined the durability of mobile phones in the e-learning context and this is something new compared to all the studies reviewed by this research.

This dissertation explores Mobile Media Technologies (MMT’s) namely, cellphones, laptops and MP3 players, and their prevalence in public space as well as how they are being used within the space. Much of my research analyses the impact of MMT’s on social behaviour and the extent to which they can be seen as the harbingers of a new “postmodern” form of social organisation. My research is predominantly an observational study which is conducted within the postmodern space of the shopping mall. Through my research I discuss the multiple spaces within the shopping mall environment and I explore how humans behave, interact and construct their identities within this space; these ideas are evaluated in terms of the “modern” and the “postmodern” paradigms. “Postmodernity” and “modernity” are not mutually exclusive and as a result there are ambivalences in terms of how individuals relate to how MMT’s are being used in public space.<br>Thesis (M.A.)-University of KwaZulu-Natal, Pietermaritzburg, 2008.

Dissertation submitted in fulfillment of the requirements for the Degree of Master Of Technology: Marketing, Durban University Of Technology, Durban, South Africa, 2016.<br>The classical view that an industry is a customer-satisfying process and not a goods-producing process is vital for all businesses to understand. Today the mobile industry have produced a smartphone which represents a dramatic departure from traditional computing platforms as they no longer represent a static notion of context, where changes are absent, small or predictable. Therefore, today’s industries need to begin the production process with customer’s needs and not with patents, raw materials, products or selling skills. With this view rather, an organisation can only create the environment and the circumstances in which the consumer could have an experience. Furthermore, an organisation cannot grant an experience to the consumer in isolation. In seeking to expand an understating of the above classical view, this study inquired into customer experience derived from owing and using the most decorated product of the era, that is, the smartphone. The essence of this study aimed at investigating customer experience by studying smartphone usage from the students’ perspective. It studied the gap between students’ expectation and the subsequent experiences in order to determine satisfaction levels. Furthermore, cognitive dissonance was investigated to determine if there were any remorse feelings towards the smartphone. A descriptive study was employed with a quantitative inquiry and the survey used the convenience sampling method. A questionnaire was administered to students within the Durban University of Technology (DUT) fraternity. The Statistical Package for Social Science Software (SPSS) version 21 was used to analyse and to interpret the data. The key findings of the study indicate that South African university students (DUT) have positive experiences with the smartphones. Albeit, the findings indicate positive experiences, minimal presence of cognitive dissonance is also depicted. The presence of dissonance highlights that an idea cannot have a single measure which is universally meaningful. Therefore, the study expose that every product will always be exposed to suggestions of change, no matter how it can be deemed smart.<br>M

M.Ing. (Electrical & Electronic Engineering)<br>This thesis investigates the problems associated with providing end to end in-service performance monitoring on leased line data networks. These problems are of both practical and theoretical nature. A solution to this problem is presented and is based on linear block coding using some overhead bandwidth available within the channel. The coding scheme relies on the characteristics of shortened cyclic codes. A method is given to obtain the undetected error probability for an arbitrary code generation polynomial with a specified degree of shortening. References to the literature explain why this type of calculation is not straightforward. This method is used to compare various candidate codes. A method is discussed which facilitates rapid isolation of groups of favourable candidate codes for further study. Software is developed to aid in the code selection process and optimum codes are selected for leased line application. It is shown that in most cases improvements in undetected error probability are achievable, when comparison is made to previously published codes, proposed for error detection. This is because code generators optimum at their published or natural coding rate are seldom optimum at the rate which results from shortening the code.

Submitted in fulfillment of the requirements for the degree of Doctor of Technology: Information Technology, Durban University of Technology, Durban, South Africa, 2015.<br>This thesis focuses on the development of an enhanced innovative secure mobile Internet voting system architecture that offers desirable security requirements to theoretically mitigate some of the intrinsic administrative and logistical challenges of voting, inter alia lack of mobility support for voters, voter inconvenience, election misconduct, and possible voter coercion often associated with the conventional poll-site voting system. Systems in existence have tended to revolve around the need to provide ubiquitous voting, but lack adequate control mechanism to address, in particular, the important security requirement of controlling possible coercion in ubiquitous voting. The research work reported in this thesis improves upon a well-developed Sensus reference architecture. It does so by leveraging the auto-coupling capability of near field communication, as well as the intrinsic merits of global positioning system, voice biometric authentication, and computational intelligence techniques. The leveraging of the combination of these features provides a theoretical mitigation of some of the security challenges inherent in electoral systems previously alluded to. This leveraging also offers a more pragmatic approach to ensuring high level, secure, mobile Internet voting such as voter authentication. Experiments were performed using spectral features for realising the voice biometric based authentication of the system architecture developed. The spectral features investigated include Mel-frequency Cepstral Coefficients (MFCC), Mel-frequency Discrete Wavelet Coefficients (MFDWC), Linear Predictive Cepstral Coefficients (LPCC), and Spectral Histogram of Oriented Gradients (SHOG). The MFCC, MFDWC and LPCC usually have higher dimensions that oftentimes lead to high computational complexity of the pattern matching algorithms in automatic speaker authentication systems. In this study, higher dimensions of each of the features were reduced per speaker using Histogram of Oriented Gradients (HOG) algorithm, while neural network ensemble was utilised as the pattern-matching algorithm. Out of the four spectral features investigated, the LPCC-HOG gave the best statistical results with an R statistic of 0.9257 and Mean Square Error of 0.0361. These compact LPCC-HOG features are highly promising for implementing the authentication module of the secure mobile Internet voting system architecture reported in this thesis.<br>D

Technology continues to progress due to the enormous growth of wireless technologies and mobile computing. Mobile devices such as handheld computers, smartphones and mobile phones are integrated into the daily lives of many people irrespective of their age, nationality or gender. These devices are embedded with computer functionalities and their ease of use and mobility functionality enable the people to use and move around with the mobile devices everywhere they go; the sophistication of these devices fascinates many learners thus they are fluent in using digital technology. The aim of this thesis is to describe how these devices are being utilised for learning purposes using the qualitative data collection method, to use the FRAME model to evaluate the usefulness of mobile digital technology and to also understand the educator’s role in the mobile age. This thesis explores the relationship between education (what is being taught), society (individual learners and their learning preferences) and technology (mobile tools used for learning), conceptualising the learner’s perspective. The research findings indicate that learners in the case study are enthusiastic about mobile educational technology, fluent in using digital technology and they prefer pen and paper for taking notes. The outcomes of this study suggest that although mobile technology has the potential to enhance teaching and learning, educators need to put more emphasis on providing technology-rich learning activities to empower high level of student involvement and take into consideration the learner’s learning preferences towards learning using mobile technology.<br>College of Engineering, Science and Technology<br>M.Tech.

During the last two decades, there have been a number of policy and legislative changes in respect of South Africa’s intellectual property (IP) and the national system of innovation (NSI). In 2012, a Ministerial Review of the Science, Technology and Innovation (STI) landscape in South Africa made recommendations to improve the STI landscape and effectively the national system of innovation. The study provides a critical review of drafts of the national IP policy published in 2013 as well as the IP Framework released in 2016 for public comment. The review of the IP and the NSI are within the context of the National Development Plan (NDP), which outlines South Africa’s desired developmental goals. South Africa is part of the BRICS group of countries (Brazil, Russia, India, China and South Africa). The South African economy is characterised by a desire to move away from being dependent on resources and commodities, to becoming a more knowledge based and innovation driven economy. It is hoped that such a move would assist the country to address some of the social and economic development challenges facing South Africa, as captured in the NDP. South Africa has a functioning IP system, but its relationship with South Africa’s development trajectory is not established. More particularly, the extent to which the IP system relates to the innovation system and how these two systems must be aligned to enable South Africa to transition successfully from a country based on the production of primary resources and associated commodity-based industries to a viable knowledge-based economy is unclear. The Trade-related Aspects of Intellectual Property Rights (TRIPS Agreement) of the World Trade Organisation (WTO) provides that IP must contribute to innovation and to transfer of technology and knowledge in a manner that is conducive to social and economic welfare. Certain provisions set out the foundations of intellectual property systems within the context of each member state. This study has thus explored the complex, complementary and sometimes contested relationships between IP and innovation, with particular emphasis on the potential of an intellectual property system to stimulate innovation and foster social and economic development. The study has also analysed the interconnectivity of IP and innovation with other WTO legal instruments, taking into account South Africa’s positioning within the globalised economy and in particular the BRICS group of countries. The research involved a critical review of South Africa’s IP and innovation policies, as well as relevant legislation, instruments, infrastructure, IP and innovation landscape, and relationship with international WTO legal instruments, in addition to its performance, given the developmental priorities and the globalised economy. The research documents patenting trends by South Africans using European Patent Office (EPO), Patent Cooperation Treaty (PCT), United States Patents and Trademarks Office (USPTO) databases over the period 1996-2015. A comparative analysis of patenting trends amongst BRICS group of countries has also been documented. The study also documents new findings, observations and insights regarding South Africa’s IP and innovation systems. Some of these, particularly in relation to higher education and research institutions, are directly attributable to the Intellectual Property Rights from Publicly Financed Research and Development Act. More particularly, the public institutions are becoming relevant players in the NSI and are responsible for growth of certain technology clusters, in particular, biotechnology. At the same time, the study makes findings of a decline of private sector participation in patenting as well as R&D investment over the 20-year period. Recommendations are included regarding specific interventions to ensure coherence between the IP and innovation systems. Such coherence and alignment should strengthen the systems’ ability to stimulate innovation and foster inclusive development and competitiveness, which are relevant for addressing South Africa’s socio-economic development priorities.<br>Mercantile Law<br>LL.

M.Tech. (Radiography)<br>Conventional film and paper based radiology departments have been replaced by information technology at a rapid rate internationally. The leading technology is the Picture Archiving and Communication Systems (PACS) and Radiology Information System (RIS). The necessity to follow global trends has become more apparent in Africa. Simultaneously, Gauteng has now reached a stage where PACS and RIS have been widely implemented. It has been recommended that radiographers must be prepared for the change in expectations and levels of accountability required when PACS and RIS are adopted into the radiology department. The research question that arises is: What are the experiences of radiographers using PACS and RIS in Gauteng, South Africa? The aim and objectives of this explanatory sequential study was to explore and describe the experiences of radiographers using PACS and RIS in Gauteng, South Africa and to develop guidelines to facilitate the job satisfaction of radiographers in a PACS and RIS-driven radiology department. The study employed an explanatory sequential mixed methods design. The explanatory design is a two-phased mixed methods design. The study began with the first, quantitative phase in which the researcher collected data from the six participating diagnostic radiology practices in the form of questionnaires. For the second phase the researcher interviewed information-rich radiographers who participated in the first phase of the data collection in focus groups. The findings, of this study, indicate that the participants in this study experience PACS and RIS in a positive manner, but that strategies could be put into place to further enhance their experience. Guidelines for facilitating job satisfaction of radiographers in a PACS and RIS-driven radiology department are suggested

Smartphone technology can be integrated in mathematics education, since most learners immerse in this technology. Teachers should be facilitators of confined learning in traditional classrooms, including digital facilitators. The aim of the study was to determine the effect of integrating smartphone technology on Grade 10 learners’ achievement in algebra. The study focused on two Grade 10 classes from different township schools in the Gauteng Province. The study was conducted during the first term of 2016. A quasi-quantitative experimental research design was used. Smartphones were integrated in algebra teaching and learning, using the Microsoft Math online application: https://www.math.microsoft.com. Despite challenges encountered during the study, the results indicated a positive impact on learners’ achievements in algebra, amongst experimental group learners. A need exists for future research in integrating smartphone technology in mathematics education.<br>Mathematics Education<br>M. Ed. (Mathematics Education)
