Os sistemas de identificação por radio frequências (RFID - Radio Frequency IDentification) são uma tecnologia de transmissão e armazenamento de informação remota, composta por dispositivos (etiquetas e leitores RFID), que comunicam à distância sem necessitarem de qualquer contato direto. Embora a RFID possua algumas décadas de existência, apenas nos últimos anos tem recebido atenção por parte do meio industrial e demonstrado ser uma tecnologia com um futuro promissor, devido especialmente às suas inúmeras possibilidades de utilização e vantagens que possui quando comparada com outras tecnologias semelhantes. Embora a utilização da RFID aparente ser bastante vantajosa e com bastantes benefícios, muitas questões e dificuldades são colocadas no momento da sua implementação. No âmbito desta dissertação será apresentado uma revisão bibliográfica sobre o estado de arte da tecnologia RFID, os dispositivos que a compõem e que são essenciais ao seu funcionamento, assim como várias aplicações da tecnologia. Serão igualmente abordados os problemas que dificultam a disseminação da tecnologia. O objetivo do trabalho foi (i) realizar um levantamento na literatura dos fatores que influenciam a eficiência da tecnologia RFID e (ii) realizar uma análise experimental dos fatores que influenciam a capacidade de transmissão do sinal de radio frequência entre os vários dispositivos RFID existentes no contexto industrial. / The Radio frequency identification (RFID) systems are a technology that permits the transmission and storage of information remotely, composed of devices (tags and readers), which communicate at a distance without the need for any direct contact. While RFID has a few decades of existence only in recent years it has received attention from the industrial environment and demonstrated to be a technology with a promising future, especially due to its many possibilities of use and advantages when compared with other similar technologies. However, although the actual use of RFID may appear to be very advantageous and with many benefits, many issues and problems are posed at time of implementation. Within this dissertation it will be presented a literature review on the state of the art RFID technology, the devices that make up to it and that are essential to its operation, as well as the various applications of technology. The problems and difficulties that are posed at the moment and difficulties that compromise the spread of technology will also be discussed. The objective of this work was (i) to conduct a literature review of the factors that influence the efficiency of RFID technology and (ii) conduct an experimental analysis of the factors that influence the ability of signal transmission between different radio frequency RFID devices existing in the industrial context.

The purpose of this study was to investigate recommendations regarding professional standards for training and registration in pastoral work. The aim is to obtain professional recognition for Pastoral Counsellors/Therapists by accreditation and recognition from a relevant professional council. The goal is also to formulate these standards in line with the processes of the South African Qualification Authority (SAQA). The following four forms of pastoral work were distinguished and discussed: Mutual care, Pastoral care, Pastoral counselling, and Pastoral therapy. The Accreditation Committee proposed the following sub-fields: Human and Social Studies (Field 07): Religious and ethical foundation of society (sub-field). Health Sciences and Social Services (Field 09): Promotive health and developmental services, Preventative health, Curative health, Rehabilitative services (sub-fields). Proposals was adopted for the following Pastoral Counselling/Therapy The purpose of this study was to investigate recommendations regarding professional standards for training and registration in pastoral work.

Proposals was adopted for the following Pastoral Counselling!Therapy qualifications: Certificate in Pastoral Counselling (Basic) Certificate in Pastoral Counselling (Post Basic), Certificate in Pastoral Counselling (Intermediate), Diploma and post graduate degrees in Pastoral Counselling (Advanced), Masters and Doctorate Degrees in Pastoral Counselling (Specialist). After narrow consultation the level descriptors were discussed and accepted. As all proposals this will still be open for changes. The following roles were described using the format of a Qualification based on Unit Standards. Unit Standards are linked to the proposed six "roles" which are seen as generic to all Pastoral Counselling practices: Maintain effective relational and communication competence, Apply and maintain professional work ethics, Plan and facilitate pastoral counselling process, Engage in an effective personal development process, Design and conduct course of treatment, Conduct research, The roles and applied competencies for the pastoral counselling/therapy specialised field were defined. These roles may be used to re-shape current qualifications, as well as to research and design new qualifications. They are intended as initial guidelines for providers. The following registered categories for pastoral counsellors/therapists were proposed by the accreditation committee and accepted by SAAP: Category 1: Basic level pastoral counsellor (NQF Level 2) Category 2: Post basic level pastoral counsellor (NQF level 3) Category 3: Intermediate level pastoral counsellor (NQF Level 4) Category 4: Advanced level pastoral therapist (NQF Level 5/6) Category 5: Specialist level pastoral therapist (NQF Level 7 /8) The following outcomes (unit standards) for Pastoral Counsellors/Therapists were identified: UNIT 1: Applying work ethics UNIT 2: Understanding pastoral counselling theory UNIT 3: Facilitating pastoral counselling skills UNIT 4: Conducting research UNIT 5: Developing self-knowledge Some of the recommendations were: It became necessary to have some form of regulation and/or even "control" to prevent the abuse of people who ostensibly suffer from mental illness. To establish professional standards for training in pastoral counselling and to obtain professional recognition for pastoral counsellors/therapists through accreditation and recognition from a relevant professional council. In doing this we should also come to an agreement on a proper set of work ethics. It was recommend that the level descriptors should be further elaborated through a careful analysis of the standards proposed, but that the process of moving from general to specific descriptors should be adopted in the absence of meaningful generic level descriptors. It was recommend that the proposed standards and qualifications should only be adopted once processes is established where an SGB has been established and registered with SAQA, and these standards and qualifications have been accepted by providers, professional Pastoral Counsellors/Therapists, professional associations, etc. / Philosophy, Practical & Systematic Theology / M.

An applied study was undertaken to describe the current position of youth work as profession in the Dutch Reformed Church and to identify factors influencing the sustainability. A review of relevant literature, as well as an empirical survey were conducted to investigate pertinent factors such as the working conditions, the person and the training of the youth worker. In the empirical research respondents completing questionnaires consisted of former students of the Huguenot College currently employed as church youth workers, and those who left the ministry. Interviews were conducted with congregations currently employing or having employed youth workers. It is evident from this study that the youth work profession is not yet satisfactorily established and thus contributes to youth workers leaving the ministry. In the interest of youth ministry, it is essential for the Dutch Reformed Church to acknowledge these factors influencing the sustainability of youth work as profession, in order to get this occupation properly established. / Practical Theology / M.Diac.
