Life-Cycle Assessment (LCA) is an analytic method for evaluation of environmental impacts of products, services and technologies. It is associated with all the stages of a product's life. The environmental impacts are evaluated on the basis of material and energetic flows, which are in influence with the environment. These impacts are always determined in the relation with the function of the product or the service and so it is possible to compare them with the other alternatives. One of the most important reasons why I have chosen this dissertation thesis subject was the growing public interest in impacts of the building constructions on the environment and human organism. Only a few experts and scientific research centres deal with the problem of environmental impacts of the buildings in the Czech Republic so the main goal of this thesis is to help with a spreading a knowledge about it. There are four main problems to solve in the thesis: determination of environmental impacts of selected materials which are missing in available databases, creation of life cycle models of evaluated buildings, determining the most appropriate functional unit and determining the contents of the recommended LCA protocol for building analysis. In the first phase of the thesis there was built a detailed life cycle model of the reference building on the basis of available documents and databases. This "cradle to cradle" LCA model was then optimized for a large number of life cycle scenarios to determine the significance of the impact of individual variables on the overall environmental impact of the building. The knowledge gained from this analysis was applied to the lifecycle models of other buildings and then there was assembled the recommended form of the LCA protocol. In the final stage, the results of the environmental impacts were quantified on the different functional units which were used for determining the appropriate form.

No. of bitstreams: 0 Previous issue date: 2009 / Este estudo visa explorar o Sistema de Comunicação de Internação Hospitalar (CIH) propondo critérios para avaliação da qualidade dos dados, com o objetivo de sinalizar a existência dos aspectos limitantes, e contribuir para a melhoria da qualidade dos dados dessa importante fonte de informação. O trabalho objetiva, também, incentivar o uso do CIH, ressaltando o seu potencial de utilização na epidemiologia e na gestão da saúde do País. Trata-se de um estudo ecológico em um banco de dados em nível nacional, no período de 2007 e 2008. A metodologia adotada na avaliação da qualidade dos dados foi baseada nas experiências do Instituto Canadense de Informação para a Saúde (Canadian Institute for Health Information) e da Rede Interagencial de Informações para a Saúde (Ripsa), adaptando-se seus conceitos e recomendações às necessidades inerentes ao CIH. O estudo demonstrou que, no período analisado, a base de dados do CIH possui fragilidade na coleta das informações, porém tem boa completitude e mostra coerência das informações na série histórica. / This study explored the Communication System for Hospital (CIH) proposing criteria for evaluating the quality of data in order to signal the existence of the limiting aspects and contribute to the improvement of data quality of this important source of information.

This is one ecological study in a database at the national level, between 2007 and 2008. The methodology used in assessing the quality of the data was based on the experiences of the Canadian Institute for Health Information and the Inter-Agency Network for Health Information (Ripsa), adapting its concepts and recommendations to the needs inherent CIH. The study showed that during the period analyzed, the database of the CIH has weakness in the data collection, but has shown good consistency and completeness of the information in the series.

Indiana University-Purdue University Indianapolis (IUPUI) Indiana University School of Dentistry Master Degree Thesis. / Detection of caries at an early stage is unequivocally essential for early preventive intervention. Longitudinal assessment of caries lesions, especially under the opaque preventive sealant, would be of utmost importance to the dental community. OBJECTIVES: The aim of this two-part in-vitro study is to evaluate the performance of multiple detection methods: The International Caries Detection and Assessment System (ICDAS); two quantitative light-induced fluorescence systems QLF; Inspektor™ Pro and QLF-D Biluminator™2 (Inspektor Research Systems B.V.; Amsterdam, The Netherlands); and photothermal radiometry and modulated luminescence (PTR/LUM) of The Canary System® (Quantum Dental Technologies; Toronto, Canada). All these are to be evaluated on their detection of caries on posterior human permanent teeth for 1) of primary occlusal lesions, and 2) under the sealant of primary occlusal lesions. METHODS: One hundred and twenty (N = 120) human posterior permanent teeth, selected in compliance with IU-IRB “Institutional Review Board” standards, with non-cavitated occlusal lesions ICDAS (scores 0 to 4) were divided into two equal groups. The second group (N = 60) received an opaque resin dental sealant (Delton® Light-Curing Pit and Fissure Sealant Opaque, Dentsply, York, PA). All lesions were assessed with each detection method twice in a random order except for ICDAS, which was not used following the placement of the sealant. Histological validation was used to compare methods in regard to sensitivity, specificity, % correct, and the area under receiver- operating characteristic curve (AUC). Intra-examiner repeatability and inter-examiner agreement were measured using intraclass correlation coefficient (ICC). RESULTS: 1) Of primary occlusal lesions, sensitivity, specificity, and AUC values were respectively: 0.82, 0.86 and 0.87 (ICDAS); 0.89, 0.60 and 0.90 (Inspektor Pro); 0.96, 0.57 and 0.94 (QLF-D Biluminator 2); and 0.85, 0.43 and 0.79 (The Canary System). Intra-examiner repeatability and inter-examiner agreement were respectively: 0.81 to 0.87: 0.72 (ICDAS); 0.49 to 0.97: 0.73 (Inspektor Pro); 0.96 to 0.99: 0.96 (QLF-D Biluminator 2); and 0.33 to 0.63: 0.48 (The Canary System). 2) Of primary occlusal lesions under the opaque dental sealants, sensitivity, specificity, and AUC values were respectively: 0.99, 0.03 and 0.67 (Inspektor Pro); 1.00, 0.00 and 0.70 (QLF-D Biluminator 2); and 0.54, 0.50 and 0.58 (The Canary System). Intra-examiner repeatability and inter-examiner agreement were respectively: 0.24 to 0.37: 0.29 (Inspektor Pro); 0.80 to 0.84: 0.74 (QLF-D Biluminator 2); and 0.22 to 0.47: 0.01 (The Canary System). CONCLUSION: Limited to these in-vitro conditions, 1) ICDAS remains the method of choice for detection of early caries lesion due to its adequately high accuracy and repeatability. QLF systems demonstrate potential in longitudinal monitoring due to an almost perfect repeatability of QLF-D Biluminator 2. The Canary System performance and repeatability were not acceptable as a valid method of early caries detection. 2) None of the methods demonstrated acceptable ability in detecting of occlusal caries under the opaque sealant. However, QLF-D Biluminator 2, with limitation to these in-vitro conditions and Delton opaque sealant, demonstrated a fair accuracy AUC (0.70) in detecting of caries under sealants at an experimental threshold of 12.5% ΔF.

The National Curriculum Statement (NCS) heralds the beginning of a new curriculum for Grades 10 to 12 in South Africa. Underpinned by the South African Constitution, and based on the tenets of Outcomes-based Education, the NCS seeks to provide contextually-relevant education for all South African learners, so that they are able to embrace inevitable change. Although the NCS highlights the importance of assessment, an analysis of the English Home Language (EHL) NCS reveals tensions between policy and practice. This study attempts to contextualise the role of relevant assessment for the 21st century. It then proceeds to engage in a historical evaluation of assessment within the NSC in terms of how assessment was conducted in the former Natal Education Department, a liberal education department within former apartheid South Africa. The conclusions drawn from the evaluation are used to provide recommendations to relieve the tensions identified within the EHL NSC. / Educational Studies / M.Ed.

This study centres on curriculum development for a master craftsman level in the Printing, Newspaper and Packaging Industries which is didactically sound and takes cognisance of the dynamic vocational education and training milieu in which it occurs. Curriculum and curriculum development is viewed from a systems perspective and incorporates the specific andragogic didactic needs of the learner target group as well as the unique needs of an industrial sector. Because the National Qualification Framework model advocates an outcomes-based approach to curriculum development this necessitated the identification of a suitable standards generating process to articulate the master craftsman unit standards into a qualification capable of being recognised by the National Qualification Framework. The nature and complexity of the underpinning knowledge, skills and competencies for the master craftsman level were quantified and qualified by means of skills and competency profiling and the development of a job outcome taxonomy of skills, knowledge and attributes which incorporated critical cross field and fundamental skills, and their underpinning knowledge requirements. Using aspects ofvarious vocational education and training models and empirical research course content was sourced, evaluated and developed into appropriate modules of learning that are congruent with the accepted competency based modular training system used in the Industries. Course maps that integrate theory and practice were developed with multi skilling milestones linked to learner certification. Evaluation of resources for the delivery of the Master Craftsman Programme was facilitated by means of a provider quality assessment and accreditation system. The interactive teaching-learning situation and the evaluation processes and procedures were developed to enhance the assessment of applied competencies in the world of work. A pilot study and unit standards generating activities are to be used as a means of implementing and institutionalising the master craftsman curriculum. The findings of this study revealed that by viewing the curriculum from a systems perspective and using a suitable curriculum development model a creative master craftsman curriculum development process could take place. The competency profiling technique and taxonomy of competencies, skills, knowledge and attributes enabled the curriculum process to be a top-down approach which is outcomes-based. / Didactics / D.Ed.
