The stigma and prejudice of leprosy: influence on the human condition

Introduction: To analyze the knowledge, feelings and perceptions involving patients affected by leprosy, as a better understanding of these factors may be useful to decrease the stigma and prejudice associated with the condition. Methods: The study cohort consisted of 94 patients who underwent treatment for leprosy at the Health Units in the City of Cuiaba, Mato Grosso (MT), Brazil. The study questionnaire included items to collect information on socio-demographic data, knowledge about the disease, stigma, prejudice, self-esteem and quality of life of leprosy patients. Bivariate analyses were used to assess the data based on the chi-square test with a 5% significance threshold. Results: The results revealed that the study population consisted predominantly of males (55.3%) with an income between 1 and 3 times the minimum wage (67%). The survey respondents reported that the most significant difficulties related to the treatment were the side effects (44.7%) and the duration of the treatment (28.7%). A total of 72.3% of the subjects were knowledgeable about the disease, of whom 26.6% had the leprosy reaction. Stigma and prejudice were cited by 93.6% of the participants. Based on the responses, 40.4% of patients reported being depressed and sad, and 69.1% of the subjects encountered problems at work after being diagnosed. A total of 45.7% of the patients rated their quality of life between bad and very bad. Conclusions: Our results suggest that leprosy causes suffering in patients beyond pain and discomfort and greatly influences social participation.

Estilo de vida e saúde de um grupo de idosos de Franca, SP

The increase of elderly population in Brazil and all around the world shows the need of reviewing the health cares in order to get a better quality of life. Objective: To evaluate lifestyle and health care of elderly participants of UNATI, Franca, SP. Methods: Sixty elderlies answered a questions about socio-economic issues, health care, food consumption habits and lifestyle, after, they were submitted to anthropometric and laboratory tests. Results: There was a prevalence of women (85%), aged between 60-69 years old (60%), up to high school (60%), retired (65%), income up to 5 minimum wage (73.4%). Most seniors assessed medical care (65%) were in use of long-term medicines (78.3%), they reported to control blood pressure (80%) and to not smoke (100%). About 71.7% people believed to have a healthy diet, 97% took meals at home, 85% chose and prepared their own food, 65% had 5-6 meals/day, 63% drank 1L of water/day, 90% had bowel function and 43.3% practices a regular physical activity. Only 13.3% have done hormone replacement therapy, 18.3% take dietary supplements and 21.7% drink alcoholic drinks. The participants presented a BMI of 27.49 ± 4.5kg/m², prevalence of overweight and eutrophy, which values decreased with age. Leg circumference (LC) (36.27 ± 3.84 cm), Arm circumference (AC) (31.39 ± 4.08 cm) and triceps skinfolds (TS) (20.58±7.54mm) values were suit in most cases (96.7, 85 and 83.3%, respectively). Serum total cholesterol values were 198.53 ± 35.2mg/dL, 55% were considered optimum. About 63.3% and 68.3% of the elderlies, respectively, presented a high density lipoproteins (HDL) (53.58± 10.9mg/dL) and triglycerides (TG) (143.97 ± 92.37mg/dL) according to the recommendation and 51.7% of the elderlies had normal glycemia, 38.3% had risk and 10% showed high blood glucose, indicating diabetes. Conclusion: Many elderlies had body mass index (BMI) above normal, indicating overweight or obesity, but the participants can be considered healthy because of AC, LC and TS values, diet habits, health care and lifestyle.

Desigualdade social no Brasil: as principais mudanças nos governos Lula

This monograph will focus on the social policies implemented by the Federal Government during the government of Luis Inácio Lula da Silva. The aim of this study is to analyze the main changes in social inequality indicators in the period 2003 - 2010. In the first chapter, we present some ideas of poverty meaning and its history in Brazil. The second chapter is dedicated to the most important cash transfer program in the history of the country, the Bolsa Familia program, and finally, in Chapter 3, is highlighted as stocks in the labor market also contributed to improve social indicators in Brazil and lift millions out of poverty and extreme poverty, such as increasing the level of formal job creation and the real increase in the minimum wage

Minimum size for the occurrence of vortex matter in a square mesoscopic superconductor

The study of superconducting samples in mesoscopic scale presented a remarkable improvement during the last years. Certainly, such interest is based on the fact that when the size of the samples is close to the order of the temperature dependent coherence length xi(T), and/or the size of the penetration depth lambda(T), there are some significant modifications on the physical properties of the superconducting state. This contribution tests the square cross-section size limit for the occurrence (or not) of vortices in mesoscopic samples of area L-2, where L varies discretely from 1 xi(0) to 8 xi(0).The time dependent Ginzburg-Landau (TDGL) equations approach is used upon taking the order parameter and the local magnetic field invariant along the z-direction. The vortex configurations at the equilibrium can be obtained from the TDGL equations for superconductivity as the system relaxes to the stationary state.The obtained results show that the limit of vortex penetration is for the square sample of size 3 xi(0) x 3 xi(0) in which only a single vortex are allowed into the sample. For smaller specimens, no vortex can be formed and the field entrance into the sample is continuous and the total flux penetration occurs at higher values of H/H-c2(0), where H-c2(T) is the upper critical field. Otherwise, for larger samples different vortices patterns can be observed depending on the sample size. (c) 2007 Elsevier B.V. All rights reserved.

Studies on the cooling minimum quantity and conventional cooling at hardened steels in grinding process

The purpose of this work is to explain the concept of cutting fluids reasonable usage through the fluid minimum quantity in grinding processes. on that purpose, the development of a new nozzle and an own and adequate methodology should be required in order to obtain good results and compare them to the conventional methods. The analysis of the grinding wheel/cutting fluid performance was accomplished from the following input parameters: flow rate variation by nozzle diameter changes (three diameters values: 3mm, 4mm and 5mm), besides the conventional round nozzle already within the machine. Integral oil and a synthetic emulsion were used as cutting fluids and a conventional grinding wheel was employed. The workpieces were made of steel VC 131, tempered and quenched with 60HRc. Thus, as the flow rate and the nozzle diameter changes, keeping steady fluid jet velocity (equal to cutting velocity), attempted to find the best machining conditions, with the purpose to obtain a decrease on the cutting fluid volume, taking into consideration the analysis of the process output variables such as cutting strength, cutting specific energy, grinding wheel wear and surface roughness. It was verified that the 3mm diameter optimized nozzle and the integral oil, in general, was the best combination among all proposed.

Analysis of surface integrity for minimum quantity lubricant - MQL in grinding

The quality of machined components is currently of high interest, for the market demands mechanical components of increasingly high performance, not only from the standpoint of functionality but also from that of safety. Components produced through operations involving the removal of material display surface irregularities resulting not only from the action of the tool itself, but also from other factors that contribute to their superficial texture. This texture can exert a decisive influence on the application and performance of the machined component. This article analyzes the behavior of the minimum quantity lubricant (MQL) technique and compares it with the conventional cooling method. To this end, an optimized fluid application method was devised using a specially designed nozzle, by the authors, through which a minimum amount of oil is sprayed in a compressed air flow, thus meeting environmental requirements. This paper, therefore, explores and discusses the concept of the MQL in the grinding process. The performance of the MQL technique in the grinding process was evaluated based on an analysis of the surface integrity (roughness, residual stress, microstructure and microhardness). The results presented here are expected to lead to technological and ecological gains in the grinding process using MQL. (c) 2006 Elsevier Ltd. All rights reserved.
