This study was conducted to ascertain which of two techniques would result in more diagnostic films of patients with possible neck trauma. Twenty individuals were examined at the Radiology Department, Universitas hospital, Bloemfontein. Two exposures were done on each member of the sample: firstly the swimmers projection and secondly the orientation of the patient's arms was reversed. <br>Using specific criteria to standardize evaluation, the films were evaluated by a radiologist. The adapted swimmers projection had better results in 50% of the categories. The swimmers projection was better in 33.3% of the categories. One category for both projections (16.7%) was equal.
Research on Quality Assurance at the Regional Learning Centre Kimberley, Central University of Technology, Free StateAuthor K.J. De BeerSource: Interim : Interdisciplinary Journal 5, pp 11 –24 (2006)More Less
Due to the new Higher Education landscape in South Africa, Universities of Technology will have to adapt to the changing socio-political scene on and off their campuses. This implies that <i>public accountability</i> is becoming the most significant vehicle of government policy and an integrated part of decision-making models. Subsequently, it also imp lies part time services to distance campuses or at regional learning centres too. In 2004, the Higher Education Quality Assurance Committee (HEQC), audited the Kimberley Regional Learning Centre of the CUT exactly according to the universal standards related to quality assurance for part time or so called distance learners. These universal concepts entail self-evaluation practices, selection approaches, efficiency and performance and of course, public accountability. In follow up reports to the HEQC what has been done to ensure better services to part time distance learners, the manager of the Regional Learning Centre and the director for distance learning launched an ongoing research project on quality assurance to find answers to problems that the HEQC audit has revealed. The following article contains the very first phase of an ongoing process to research universal standards that implies universal standards for other universities of technology as well.
Wavelets and short time fourier transforms on ultrasonic doppler signals for pregnancy determination in sheepAuthor G.D. JordaanSource: Interim : Interdisciplinary Journal 5, pp 25 –37 (2006)More Less
The reproductive status of animals is of utmost importance to the modern farmer. Decisions concerning the management of the flock are influenced by the knowledge of the percentage of animals that are pregnant at any specific time. The aim of the project was to gain knowledge for the development of an instrument that is affordable and with which a farmer can do pregnancy determination himself/herself, thereby enabling him/her to make the correct management decisions. Experimental data were obtained from pregnant Dorper ewes with the aid of a portable Doppler instrument. Using real data as input, simulations of Wavelet and Short Time Fourier Transforms (STF) were done in MathCAD. In the simulations known levels of noise were added to the Doppler signals. Satisfactory results were obtained from the simulations of Wavelet Transforms. In the simulation of the Wavelet Transforms, signals with a SNR of -6.5 dB were successfully identified. It can thus be concluded that Wavelet Transforms can be used successfully for the detection of the fetal heartbeat in noisy ultrasonic Doppler signals.

Mathematics teachers need an uncomplicated yet effective programme that they can use to type documents that contain mathematical symbols and notation. Many such programmes exist on the market, but are costly and in most cases, difficult to use. Microsoft Word's Equation Editor provides a solution to this problem in that it is easy to use and readily available in the Microsoft package. An investigation into how third-year education students respond to the presentation and use of this programme was made. The research was executed in the form of a case study, as only third-year mathematics students from the School of Teacher Education at the Central University of Technology, Free State, participated. It was found that these students grasped the concepts needed to use the Equation Editor quite easily, although the level of application by the academically stronger group of students was much higher than the level reached by the weaker academic group.
Die nie-patologiese ontoerekeningsvatbaarheidsverweer van outomatisme in die Suid-Afrikaanse strafregAuthor Hein LambrechtsSource: Interim : Interdisciplinary Journal 5, pp 45 –54 (2006)More Less
A controlled, voluntary human act is the basic element of criminal liability. If the act is not subject to the will, it is involuntary and excludes the act and therefore criminal liability. This defence is known as automatism. <br>This condition of involuntariness can arise as a result of insanity or due to reasons other than insanity. If the accused were insane at the time of committing the offence and he successfully raises an automatism defence, he is sent for mandatory confinement in a psychiatric institution. The problem created by this legal provision of mandatory confinement is that an accused who was insane at the time of the crime, but sane at the time of the trial, must be confined in a psychiatric institution even though he is considered sane. In order to avoid this injustice, the courts have distinguished between ""insane automatism"" and ""sane automatism."" Cases where an involuntary action has occurred for reasons other than insanity have involved a defence of ""sane automatism"" and, if successful, have resulted in full acquittal. The reason for creating the term ""sane automatism"" was to avoid the said unjustified functioning of the law. <br>Amendments to legislation in South Africa have given courts wider discretion and they are no longer compelled to confine the accused to a psychiatric institution. The legislation is no longer unjust, with the result that the distinction between ""insane automatism"" and ""sane automatism"" is no longer necessary. <br>The automatism defence (no longer ""sane automatism"") must still be retained, but as an ordinary defence that is indicative of an involuntary act, and therefore the absence of one of the elements of a crime (but without a specific indication of whether it is sane or insane automatism). Automatism must therefore be limited to grounds for exclusion of the element of an act, i.e. the voluntary and personal conduct of the accused.

Quality Assurance has changed drastically in the last five years and these changes have impacted heavily on the operation of Higher Education Institutions in South Africa. The paper will review the process of quality assurance from as early as Certification of Council of Technikons Education (SERTEC) and Quality Promotion Unit (QPU) days. SERTEC and QPU did, pave the way for the Higher Education Quality Committee (HEQC) to perform its roles as assigned by the Council of Higher Education (CHE).

The contemporary challenge facing all Higher Education Institutions (HEI's) since 1994 focuses on generating methods to broaden the access for schoolleavers who are ill-prepared and not ready for higher education. In response to this challenge the CENTRAL UNIVERSITY OF TECHNOLOGY, FREE STATE'S SCHOOL FOR ENTREPRENEURSHIP AND BUSSINESS DEVELOPMENT (SEBD) developed and presented a foundation programme since 2001. This article is aimed at assessing its success. Although the success rate of the first intake was very low the author believes that by modifying the programme on a continuous basis, it has a justifiable place in the Institution's ""access with success programme"".

A large number of estate agents entered the real estate industry in the last few years. At the same time the client rating of the quality of services offered by estate agents in the industry followed a downward trend. This perception of poor quality is causing a negative impact on the industry. Research done in 2004 has identified that clients within the Bloemfontein region are generally not satisfied with the level of service delivery by estate agents within the industry. <br>Respondents did identify certain areas that could be improved in order for estate agents to deliver a superior level of service. On the basis of this research and recommendations, it was possible to develop a model of the service delivery that will maximise the satisfaction of both buyers and sellers.

In most manufacturing areas there is concern with quality assurance and developing cost-effective automated inspection systems that can provide feedback necessary for closed-loop manufacturing. <br>A Machine Vision system can perform quick, repetitive inspection on large numbers of products and operate 24 hours a day. It can identify materials and components, locate and orient parts and verify proper assembly. The measurement, alignment or verification results can be logged on a database for later reference, e.g. when there is a customer complaint or fabrication fault. <br>Certain parameters will restrict the capability of a Machine Vision System in some or other way. The goal is to establish all parameters that will influence the capabilities of the Machine Vision system and to minimize the restrictions they cause.
