Every vehicle or truck manufacturer maintains databases regarding the service information oftheir vehicles. In this thesis, two vehicle databases: Vehicle Specification Database andMaintenance Service Database are analyzed and compared. The purpose is to explore theconnection between vehicle specification and vehicle maintenance needs. The approach is touse different clustering algorithms(Hierarchical, K-means, Spectral), distance measures (PositiveMatching Index and a modified Positive Matching Index), cluster validity measures(Rand Index,Jaccard Index) and data representations(Binary, Frequency) on these databases to determinethe important maintenance related specification attributes and their relation to differentservice problems (e.g. engine, brake, clutch) The clustering results indicate that there is arelation between vehicle specification and vehicle maintenance profiles. Different data miningrules that connect vehicle specification with vehicle maintenance needs are derived from theclustering results.

Foram realizados quatro ensaios experimentais, utilizando 392 codornas japonesas no pico de postura em cada ensaio. Os ensaios foram delineados inteiramente ao acaso, com sete tratamentos e sete repetições compostas por sete aves. Os tratamentos consistiram de níveis crescentes de cada aminoácido teste. Os níveis propostos de lisina variaram de 0,402 a 1,409%, met+cis de 0,347a 1,155%, treonina de 0,254 a 0,845% e triptofano de 0,089 a 0,296% dos aminoácidos teste. Esses níveis foram estabelecidos para compreender todas as exigências (mantença, resposta e estabilidade ou platô de resposta). Para cada aminoácido foi estudado um nível controle com objetivo de confirmar a limitação do respectivo aminoácido teste. O período experimental foi de sete semanas, sendo três de adaptação e as outras quatro para elaboração do modelo fatorial. Nesse período foram acompanhados o consumo de ração, a produção de ovos, o peso de ovos e o peso corporal. As variáveis estudadas foram, consumo de ração (g), consumo do aminoácido teste (g/ave/dia), peso médio do ovo (g), massa de ovos (g) e peso das aves (g). As respostas de produção foram ajustadas pelo modelo broken line e modelo fatorial para fracionar as exigências em mantença e produção de ovos, bem como calcular o nível para otimizar a massa de ovos da população. Além disso foi estimado as exigências dos aminoácidos pelo Reading Model. O modelo broken line estimou a máxima resposta para massa de ovos de 9,67; 9,31; 9,49 e 10,37 g / d para Lis, Thr, Met + Cys e Trp, respectivamente. Os valores de m determinados pela função monomolecular foram de 156, 64, 176 e 47 mg / BWkg0,75 por dia e os valores de a determinados pela linha tracejada com duas inclinações foram de 21, 17, 15 e 4 mg / g para Lis, Thr, Met + Cys e Trp. A ingestão de aminoácidos, a produção de massa de ovos (EO) e peso corporal (PC) foram utilizadas para ajustar os parâmetros do Reading Model. Com base nos parâmetros foi aplicado o método da equação exata e de simulação considerando, 10.000 aves. A recomendação de ótimo econômico baseada na equação exata foi 308, 231, 189 e 65 mg de Lys, MetCys, Thr e Trp por ave.dia, respectivamente. Aplicando a simulação a recomendação para Lys, MetCys, Thr e Trp foi de 287, 219, 181 e 63 mg por ave.dia, respectivamente. / The objective of this research was to determine the responses to Japanese quails and the elaboration of mathematical models for the determination of the levels of lysine, threonine, tryptophan and methionine + cystine water intake. Four experimental trials were carried out using 392 Japanese quails Posture peak in each test. The trials were designed entirely at random, with seven treatments and seven replicates composed of seven birds. Treatments consisted of increasing levels of each amino acid test. Proposed lysine levels ranged from 0.402 to 1.409%, met + cis from 0.347 to 1.155%, threonine from 0.254 to 0.845% and tryptophan from 0.089 to 0.296% of the test amino acids. These levels were established to understand all requirements (maintenance, response and stability or response plateau). For each amino acid a control level was studied in order to confirm the limitation of the respective amino acid test. The experimental period was seven weeks, three of them being adapted and the other four for elaboration of the factorial model. In this period, the consumption of feed, egg production, egg weight and body weight were monitored. The variables studied were feed intake (g), test amino acid consumption (g / bird / day), mean egg weight (g), egg mass (g) and bird weight (g). The production responses were adjusted by the broken line model and factorial model to fractionate the maintenance and egg production requirements, as well as to calculate the level to optimize the egg mass of the population. In addition, the amino acid requirements of the Reading Model were estimated. The broken line model estimated the maximum response for egg mass of 9.67; 9.31; 9.49 and 10.37 g / d for Lys, Thr, Met + Cys and Trp, respectively. The values of m determined by the monomolecular function were 156, 64, 176 and 47 mg / Bwkg0.75 per day and the values of a determined by the dashed line with two slopes were 21, 17, 15 and 4 mg / g for Lys , Thr, Met + Cys and Trp. Amino acid intake, egg mass (EO) and body weight (BW) were used to adjust the Reading Model parameters. Based on the parameters, the exact and simulation equation method was applied considering 10,000 birds. The optimum economic recommendation based on the exact equation was 308, 231, 189 and 65 mg Lys, MetCys, Thr and Trp per day, respectively. Applying the simulation the recommendation for Lys, MetCys, Thr and Trp was 287, 219, 181 and 63 mg per day, respectively. / CNPq: 141920/2013-0 / CNPq: 141748/2016-8

Approximately 55% of intensive care unit (ICU) patients require the use of a central venous catheter (CVC). CVCs are often an essential component of care; however, CVCs can create avenues for pathogens to enter the bloodstream and cause a central line-associated bloodstream infections (CLABSI), which can lead to increased mortality and morbidity, prolonged length of stay, increased cost of care, decreased patient satisfaction, and increased workload. In 2017, the CLABSI rate at the project site was 4.3 per 1,000 catheter days as compared to the national rate of 0.8 per 1,000 catheter days. Based on Piaget's theory of constructivism, a simulation-based staff educational program was developed and implemented by ICU staff (n=20). Following the implementation of the simulation-based program, adherence to CVC maintenance guidelines improved from 41.5% to 87.9%. A sample t-test showed that this improvement was statistically significant and the CLABSI rate declined to 1.24 per 1,000 catheter days in the 4-week period following implementation of the program. Findings show that introducing a simulation-based training program might help to reduce CLABSI rates in the ICU setting and contribute to positive social change by improving health outcomes in ICU patients with a CVC.

This short dissertation briefly examines the English law statutory provisions and the English judicial approach relating to the clean break principle. A comparison between English law and South African law (in particular s 7 of the Divorce Act 70 of 1979) shows the latter to allow the application of the clean break principle, but rigidity in the legislative wording and further rigidity in the wording by the courts result in the clean break principle not being a dominant feature of South African divorce law. A detailed analysis of South African case law follows in which the fundamental issues relative to the clean break principle are examined, namely the one third rule, universal partnership, misconduct and its effect on court orders, the nature of a contribution and what property is distributed on divorce. Trends in maintenance orders are looked at and how these affect the clean break principle, in particular rehabilitative maintenance and token maintenance wards. / Law / LL.M.

The research dealt with the implementation of Gestalt play therapy for the treatment of the sexually abused primary school child who experiences problems to maintain himself. The need for research on the theme originated from the researcher's experience with sexually abused primary school children. The aim of the research was to render therapeutic support to the primary school child through Gestalt play therapy, in order to explore the influence of such support on the child's maintaining behaviour. The applied research design was used for this purpose. For the purpose of the research, one sexually abused child who experienced problems to maintain himself was identified by means of purposeful sampling. During each Gestalt play therapy session the child was brought into contact with his senses. Conclusions as well as recommendations were formulated as a result of the research. / Social Work / M.

Greenery in towns and cities are an important part of our lives and influences us in many positive ways. In the Czech Republic, the establishment, restoration and maintenance of public green areas within the competence of municipalities. As with every other public service there arises a problem with the quantity and quality of its provision. This paper deals with the relationships that developed in 2011 between spending on public greenery and various parameters of the municipalities. These relations are implemented by means of two hypotheses. The first is based on economies of scale, and assumes that the larger the municipality, the smaller expenses should be provided for public green areas per inhabitant. The second hypothesis is based on the work of Carruthers and Úlfarsson (2008) and says that a higher the population density reduces the per capita expenditures of city govenments. The validity assessment of the hypotheses is done by use of the statistical method of regression analysis. This, however, did not confirm the validity of any of them. Thus there is no indirect relationship between the size of the municipality or population density and public expenditures on green areas per capita. The reason why there is no relationship lies primarily in the great freedom of decision-making of individual municipalities, as far as public green is concerned.

Because women are predominantly responsible for childcare, men are the primary income earners. Having acquired the marital assets, on divorce the husband would retain them in a marriage out of community of property. The wife would be left deskilled, financially dependent, with little likelihood of receiving spousal maintenance and with no marital assets. In 1984 the Matrimonial Property Act and in 1988 the Matrimonial Property Law Amendment Act introduced a judicial discretion to equitably redistribute marital assets in certain marriages out of community. This dissertation argues that the bases for the limitation of the judicial discretion to women married before a certain date are unsound and that the limitation arguably violates the equality clause of the Constitution. / Law / LL.M.
