- Description: This paper investigates the technical advancement in the production of ethanol in Southern Africa and examines the utilisation of ethanol and of the by-products derived from its production process. Although numerous studies have identified the use of ethanol as an alternative energy source especially in Brazil and the USA, very little data and analytical attention has been given to Southern Africa. This paper therefore builds on that and on the study done on alternative energy in Southern Africa such as the coal to liquids processes by Sasol. The paper demonstrates that the expansion of bio-ethanol as an alternative fuel would result in the reduction of Greenhouse gasses emissions and an increase in the rural economic development in the Southern African region. In conclusion the paper emphasises the need for a speedy upgrading of the ethanol technological methods in order to expand the use of bio-ethanol as an alternative energy. In addition the paper strongly recommends the supplementation of coal for the generation of electricity, as well as the progressive replacement of petroleum fuelled vehicles with the ethanol blend or the complete replacement with ethanol-fuelled ones.

- Description: Modern technology has enabled global integration with an immense opportunity for sharing knowledge. This paper examines the impact of modern medical technology on the Gauteng medical services. Gauteng is the smallest of the nine provinces in South Africa with the highest population. It produces 33.9% of the GDP of South Africa, equivalent to 10% of that of the entire African continent. Gauteng has the fourth largest economy in Africa after Algeria. Although numerous studies have identified the impact of technology on the medical fraternity, little data and analytical attention has been given to South Africa regarding modern technology, especially its impact on medical tourism. Patients from poor countries lacking modern technology travel to South Africa to benefit from technology that has improved diagnosis and made surgery quick, safe, efficient, and reduced the post-operative recovery to a few days. A multi-case approach was used in this study to explore the benefits of modern technology on the health care services. An in-depth analysis was conducted on two public and two private hospitals, selected because of their location in Gauteng and their bed capacity. A five point Likert questionnaire was administered to the hospital managers, nurses, doctors and medical technologists. In conclusion the paper emphasises the need for improved environmental friendliness by utilising paperless medical records and prescriptions, and recommends upgrading technological acuity of policy makers and healthcare Managers about the impact of Medical Technology in Disease management.

- Description: This paper investigates the non-compliance of most Business Processes in the implementation of the goals and targets of commercial Banks in Gauteng South Africa. The Banks lose millions of Rands, as a result of staff not adhering to the Business processes. The non-compliance has a major impact on the successful implementation of bank strategy. The study explores why staffs do not adhere to business processes and establishes their level of understanding and maturity in terms of business processes. The study was conducted in selected branches chosen randomly in Gauteng Province. The analysis done was on data obtained from audit reports, bank investigative reports and financial loss data reports provided by different branches. Questionnaires were also administered to staff in the different branches to understand their own perspective. It is evident from the research that non adherence to processes have a financial and reputational impact on the Banks. Non adherence also has detrimental and adverse impact on achieving overall objectives of the Banks. The most common areas not adhered to were notably; identification and verification of customers; transactions not authorised according to laid down procedures; customers cards not cancelled immediately when reported lost or stolen. The paper then concludes with several recommendations to Bank Management and Strategy implementers on how to use technological methods to check and monitor these processes.

- Description: This paper investigates the technical feasibility of microwave assisted artisanal mining in the production of Sandstone from QwaQwa in South Africa. It further discusses the cultural acceptability by the rural community of the synergetic application of the emerging technology (microwave energy) and the renewable resource (solar). Sandstone in QwaQwa, Free State is artisanally mined using chisels and hammers. This form of mining is extensively laborious and is normally accompanied by numerous casualties. The paper demonstrates the existence and the possible utilization of alternative methods including emerging technologies which are more productive, efficient, effective and sustainable. The solar energy systems are used to trigger the microwave magnetron which results into high energy microwave dosage. The dosage causes differential or selective heating on the rocks which culminate into rock breaking along the interfacial grain boundaries between the different constituting minerals. The data used in the analysis was collected by administering questionnaires to the artisanal mining community in QwaQwa and from observations made on site as well as desk top information obtained from secondary sources. The paper contributes to knowledge by drawing on the solar energy systems to generate the dosage required to trigger the microwave magnetron used to facilitate a more efficient and economical artisanal mining of sandstones. In conclusion the paper recommends to policy makers the application of microwave energy in mineral artisanal mining and processing instead of the manual chisel and hammer currently being utilized country wide. It then gives a detail analysis of the technical, scheduling and economic analysis of the sandstone artisanal mining in QwaQwa.
