This study aimed to validate tools for evaluating the ability and knowledge about blood pressure (BP) among nursing students. It is a cross-sectional, descriptive, quantitative and methodological study accomplished at the Universidade Federal do Rio Grande do Norte (UFRN), Universidade do Estado do Rio Grande do Norte (UERN) and a private university of the state. The sample consisted of 27 judges of research selected from the inclusion criteria: nursing, teachers of the semiology and/or semiotics discipline, with at least 1 year of experience, being from UFRN, EEN, UERN and private university of the state and and agree to participate voluntarily with the signing of the consent form. The research was development in three stages: construction of two instruments based on the scientific literature, resulting in a structured checklist consists of 28 items and a knowledge questionnaire with 12 questions; submission of the instruments to the judges, in the period from June to September 2012, which should evaluate each item in appropriate , appropriate with changes and inappropriate , addition to making an overall assessment of each instrument based on 10 requirements; validation and verification to the level of agreement among the judges, through the application of Kappa and Content Validity Index (CVI). Was used the consensus level greater than 0.61 (good) to the Kappa index and greater than 0.75 for CVI. Was approved by the Ethics in Research / HUOL. After being coded and tabulated, the data were analyzed using descriptive statistics. Of the 27 judges who evaluated the instrument, 77.8% are female, with a mean age of 36.6 (± 9.0) years, 63.0% worked in UFRN, 74.1% had academic master and 63.0% worked exclusively on teaching. Average length of teaching experience was 7.9 (± 8.0) years and in the semiology and/or semiotics discipline of 5.5 (± 6.7) years. In the judgment of structured checklist and questionnaire of knowledge about blood pressure mensurement any item/question was considered inappropriate since all obtained level of agreement within the indices established (CVI> 0,75 E Kappa> 0.61). In relation to structured checklist, of those 28 items present, 9 showed perfect concordance index (CVI = 1.00, Kappa = 1.00) and another 19 were considered appropriate with changes, especially with regard to clarity and vocabulary. In the questionnaire of knowledge, among the 12 questions that comprised, 7 had perfect concordance index and the others were considered appropriate with changes as requirements as clarity, vocabulary, and feasible sequence of instructional topics. In terms of a overall evaluating of instruments, the structured checklist got CVI of 0.94 and Kappa of 0.89 and the knowledge questionnaire, CVI of 0.97 and a kappa of 0.94. Both instruments proved to be valid as to their content, configuring it as clear and objective tools of assessment of knowledge and ability on blood pressure, being of nursing students as well as others students and health professionals, since the use of valid measures seeking to reduce the risk of distorting the results

The purpose of this study is to describe the implementation of the Low Energy Electron Diffaction (LEED) technique in the Laboratory of Magnetic Nanostructures and Semiconductors of the Department of Theoretical and Experimental Physics of the Universidade Federal do Rio Grande do Norte (UFRN), Natal, Brazil. During this work experimental apparatus were implemented for a complete LEED set-up. A new vacuum system was also set up. This was composed of a mechanical pump, turbomolecular pump and ionic pump for ultra-high vacuum and their respective pressure measurement sensors (Pirani gauge for low vacuum measures and the wide range gauge -WRG); ion cannon maintenance, which is basically mini-sputtering, whose function is sample cleaning; and set-up, maintenance and handling of the quadrupole mass spectrometer, whose main purpose is to investigate gas contamination inside the ultra-high vacuum chamber. It should be pointed out that the main contribution of this Master's thesis was the set-up of the sample heating system; that is, a new sample holder. In addition to the function of sample holder and heater, it was necessary to implement the function of sustaining the ultra-high vacuum environment. This set of actions is essential for the complete functioning of the LEED technique

Schizophrenia is a severe and persistent mental illness; diagnosis occurs mainly during adolescence. The pharmacological treatment is done with typical and atypical antipsychotics. Atypical have the advantage of reduced extrapyramidal effects, which make them promising for the treatment of schizophrenia, furthermore, they have shown significant metabolic and hormonal changes. The objective of this study was to evaluate the influence of atypical antipsychotics, olanzapine and risperidone on the quality of life and on their adverse effects in schizophrenic patients. For this we analyzed the quality of life of patients with implementation of EuroQol-5D-3L instrument and performing biochemical and hormonal tests, blood pressure measurement, and measurement of anthropometric indices, besides the application of Ugvalg scales for Kliniske Undersgelser (UKU) and Simpson-Angus, who evaluated the side effects caused by drugs. Data were analyzed using the Student t test and chi-square test, with 5% significance level. The results showed that the EuroQol the antipsychotic olanzapine causes significant losses associated with personal care (p <0.001). Comparing the two groups of antipsychotics, the average years of quality-adjusted life, known per QALY was favorable for the risperidone group (p <0.032). The results of olanzapine and risperidone groups were compared. In terms of socioeconomic, it was observed that men used, the prevalent form, olanzapine (p <0.008); this same group showed the following results significantly unfavorable, related to anthropometric variables: waist circumference (p <0.01), hip circumference (p <0.02), weight (p <0.02) and blood pressure (p <0.04). The biochemical and hormonal analyzes showed that olanzapine resulted in losses related to the following variables: triglycerides (p <0.04), HDL cholesterol in men (p < 0.02) and cortisol (p < 0.01). In risperidone users, the only negative value was prolactin (p < 0.04). Regarding the analysis of the Simpson-Angus scale, the group treated with olanzapine was handicapped because the average total scores for olanzapine was 0.38, while for risperidone was 0.11 (p < 0.02). In the UKU scale, the following results were obtained also unfavorable for the olanzapine group: fatigue (P <0.02), dystonia (p <0.01) and tremor (p <0.03). According to the UKU scale, the side effects present in the risperidone group included: gynecomastia (p <0.01), ejaculatory dysfunction (p <0.02) and erectile dysfunction (p <0.02). It was concluded that olanzapine users had the worst score of quality of life, higher metabolic risks associated with overweight and inadequate lipid profile and greater tendency to extrapyramidal manifestations. However, risperidone users were more likely to adverse reactions due to hormonal changes.
