The aim of this research is to describe and analyze the realization of the /R/ at the end of the syllable (coda) in the city of Uberlândia-MG, taking into account variationist aspects and possible phonological phenomena that permeates the variable realization of this segment. We used the labovian variationist methodology, that gave us the needed support to investigate and systematize the variation of one linguistic community. The corpus was compound by 5139 occurrences of /R/, which 2528 were retroflex realizations, 2480 were deletions and 132 were occurrences of other segments. The informants of this research were stratified by: sex; age group; scholarly; they were born in Uberlândia or they arrived in this city before fifth birthday. Beyond the extralinguistic variables (sex, age group and scholarty), we established as linguistic variables: following context; previous context; tonicity of syllable; lexical item; coda position in the syllable; and, at last, the word size. After the statistic analisis computed by the Goldvarb software, the favoring contexts to the retroflex realization were: coronal segments in the following context; labial segments in the previous context; unstressed syllables; nouns and others (non verbs); and words with one syllable. The favoring contexts to deletion were: dorsal segments int the following context and verbs. The extra linguistic variables favored the variation less scholarty. So, the factors male sex and age group from 26 to 49 years favored the retroflex variant, while the factors female and the age group with more than 49 years favored the deletion.

Metabolic syndrome (MS) is defined as a set of cardiovascular risk factors including obesity, systemic high blood pressure (SHBP), changes in glucose metabolism and dyslipidemia. The prevalence of MS in renal transplant recipients (RTR) ranges from 15% to 65%, increasing the risk of cardiovascular disease (CVD) and reducing renal allograft survival in the long term. The objectives of this study were to determine the prevalence and frequency of MS in renal transplant patients according to gender and time of transplantation and to evaluate renal function in patients with and without MS. Patients and Methods: Crosssectional study conducted from August 2012 to September 2013 involving 153 renal transplant recipients. MS was defined according to the National Cholesterol Education Program (NCEP) Adult Treatment Panel III (ATP III). The sample was divided into two groups: patients with metabolic syndrome (WMS patients) and patients without metabolic syndrome (WoMS patients) and according to gender. The WMS patients were stratified into quartiles according to the renal transplantation period (RTP), and variables related to MS were analyzed for both sexes. Results: MS was diagnosed in 58.1% of the studied population, specifically in MS was found 58.4% of men and 41.6% of women (P ˂ 0.05). The male and female with MS were 48.8 ± 11.6 years old vs. 47.1 ± 12.7 years old and the time of post transplantation was 76.1 ± 76.5 months vs. 84.7 ± 65.4 months, respectively (P >0,05). When we compared the sexes in the WMS group, systolic blood pressure (SBP) was higher in men (137.0 ± 18.1 vs. 128.9 ± 13.6 mmHg, P= 0.029), while the other components of MS did not exhibit significant differences. With respect to renal function, when we compared the sexes in the WMS group, the serum creatinine (sCr) was higher in men (1.73 ± 0.69 vs. 1.31 ± 0.47 mg/dL, P= 0.0012), while the urinary protein/creatinine ratio was higher in women (0.48 ± 0.69 vs. 0.37 ± 0.48 mg/dL, P=0.0150). We found no significant difference in the estimated glomerular filtration rate (eGFR) between WMS and WoMS patients for women and men (50.6 ± 19.1 vs. 50.1 ± 18.3 mL/min/1.73 m², P=0.909). We found a significant positive association between eGFR and HDL-c levels (r=0.3371; P=0.0145) for WMS men. The MS components showed no significant differences in RTP for different interquartile ranges, except for diastolic blood pressure (DBP) in women, where there was a significant variation among the quartiles evaluated (P=0.0009). Conclusion: the prevalence of MS was similar in the different quartiles in both sexes, in relation to time post TX. There was no significant difference in eGFR in patients WMS and WoMS, in both sexes. Concluding that the MS did not vary in relation to time post transplant.

In 2004, the National Institutes of Health made available the Patient-Reported Outcomes Measurement Information System – PROMIS®, which is constituted of innovative item banks for health assessment. It is based on classical, reliable Patient-Reported Outcomes (PROs) and includes advanced statistical methods, such as Item Response Theory and Computerized Adaptive Test. One of PROMIS® Domain Frameworks is the Physical Function, whose item bank need to be translated and culturally adapted so it can be used in Portuguese speaking countries. This work aimed to translate and culturally adapt the PROMIS® Physical Function item bank into Portuguese. FACIT (Functional Assessment of Chronic Illness Therapy) translation methodology, which is constituted of eight stages for translation and cultural adaptation, was used. Fifty subjects above the age of 18 years participated in the pre-test (seventh stage). The questionnaire was answered by the participants (self-reported questionnaires) by using think aloud protocol, and cognitive and retrospective interviews. In FACIT methodology, adaptations can be done since the beginning of the translation and cultural adaption process, ensuring semantic, conceptual, cultural, and operational equivalences of the Physical Function Domain. During the pre-test, 24% of the subjects had difficulties understanding the items, 22% of the subjects suggested changes to improve understanding. The terms and concepts of the items were totally understood (100%) in 87% of the items. Only four items had less than 80% of understanding; for this reason, it was necessary to chance them so they could have correspondence with the original item and be understood by the subjects, after retesting. The process of translation and cultural adaptation of the PROMIS® Physical Function item bank into Portuguese was successful. This version of the assessment tool must have its psychometric properties validated before being made available for clinical use.

The Course “Light and Life”, which is a product of the present research, is a mediator in helping Science Teachers on how to deal with the Physics classes in secondary school. The aim of the present study was to propose a course which can help Science Teachers with their difficulties in the teaching of Physics in the later years of secondary school, mainly about topics related to the theme Light. The elaboration of the product of this research involved structuring and applying a course of continued formation through the “Fun with Science and Art Museum-DICA, under the theme Light, to Science Teachers of the later years of secondary school, in order to promote an environment of dialogue and problem raising as means of disseminating and discussing the teaching of topics related to Light in the teaching of Sciences. The formation course presented a flexible structure in order to widen the relation between the researcher and the teachers participating in the course, aiming to give an answer to the formative needs of the teachers in relation to the theme proposed. In order to know and discuss the problems and challenges of the teaching of Physics in the Science classes, an approach of insertion and integration of concepts related to the theme Light was conducted, mainly on topics relating to the contents of Physics, Chemistry and Biology, according to the curriculum and the abilities of Sciences worked on in class, through the approach of concepts and practice which approximate the practical and theoretical reality of the formative needs of the teachers involved in this study. This work aimed to understand the relation of Science Teachers with the theme Light and comprehend the relation of the teachers with the present proposal of continued formation promoted by the Museum DICA. The methodological option of this research remained in the domains of qualitative research whose analysis was based on the content analysis. The data collection was carried out through questionnaires and group discussions recorded in audio, besides the participative observation of the researcher. As the research product, the structuring and application of a course of continued formation of Science Teachers of secondary school was proposed, under the thematic Light, and a later restructuring of the course under the same thematic based on the data collected after the application of the referred course, which will be later promoted by the Museum DICA.

This work's objective is the development of a methodology to represent an unknown soil through a stratified horizontal multilayer soil model, from which the engineer may carry out eletrical grounding projects with high precision. The methodology uses the experimental electrical apparent resistivity curve, obtained through measurements on the ground, using a 4-wire earth ground resistance tester kit, along with calculations involving the measured resistance. This curve is then compared with the theoretical electrical apparent resistivity curve, obtained through calculations over a horizontally strati ed soil, whose parameters are conjectured. This soil model parameters, such as the number of layers, in addition to the resistivity and the thickness of each layer, are optimized by Differential Evolution method, with enhanced performance through parallel computing, in order to both apparent resistivity curves get close enough, and it is possible to represent the unknown soil through the multilayer horizontal soil model fitted with optimized parameters. In order to assist the Differential Evolution method, in case of a stagnation during an arbitrary amount of generations, an optimization process unstuck methodology is proposed, to expand the search space and test new combinations, allowing the algorithm to nd a better solution and/or leave the local minima. It is further proposed an error improvement methodology, in order to smooth the error peaks between the apparent resistivity curves, by giving opportunities for other more uniform solutions to excel, in order to improve the whole algorithm precision, minimizing the maximum error. Methodologies to verify the polynomial approximation of the soil characteristic function and the theoretical apparent resistivity calculations are also proposed by including middle points among the approximated ones in the verification. Finally, a statistical evaluation prodecure is presented, in order to enable the classication of soil samples. The soil stratification methodology is used in a control group, formed by horizontally stratified soils. By using statistical inference, one may calculate the amount of soils that, within an error margin, does not follow the horizontal multilayer model.

The nursing staff is now the largest contingent of professionals in healthcare environments, with more than 1.8 million professionals, and of these 15% are men, showing a masculinization of the historical profession and culturally conceived and carried out by women (COFEN / FIOCRUZ, 2013). This dissertation discusses the profession forward to some issues related to gender, quality of life and night work. Objective: To analyze the impact that shift work has the professional quality of life male, through a specific instrument to identify the main problems and joint damage to that front group to his professional activity. Methods: descriptivo, Cross-sectional study with a quantitative approach, performed with 72 professional male nursing staff, 41 (56.9%) nursing technicians, 18 (25%) of nursing assistants and 13 (18.1%) of nurses, in January 2015 in a university hospital in the city of Uberlândia (Minas Gerais). For this, we used the WHOQOL-BREF questionnaire. Quantitative variables were described as mean, standard deviation, maximum and minimum, in addition to the Shapiro-Wilk test and Kruskal-Wallis used in the data analysis, with a confidence level of 5% (p <0.05). Results: the profile of respondents, most are married 42 (58.3%) under the employment contract via Single Legal Regime 50 (69.4%) with mean age of 40 and having 16 years of service; and within a range of 0 to 100, the areas with better evaluation were the Social Relations (70.1) and psychological (67.5); already the worst were the Environment (57.4) and Physical (65.4). In the overall assessment, the average was 63.3 and staying below the national average (65-70). Thus, the professionals who were married obtained better scores, regardless of the category which is in the nursing team. Conclusions: The group is average, taking into account the standard deviation, but we can say that working conditions affect their profession, and these results allow the detection of the difficulties experienced by men of the nursing team, and can cooperate with the design strategies that benefit or minimize the search for conflicts that affect the health of these workers and their quality of life.
