title: Meanings of work for manicurists and hairdressers: employees and pejotizados

description: Abstract The research aimed to identify the differentiation of meanings of work among beauty salon workers, considering the work contracts and the functions performed (hairdressers and manicurists), in a context of pejotização and functions’ internal hierarchy. We applied questionnaires to 171 manicurists and hairdressers with the following types of links: employee, informal, MEI pejotizado and MEI não pejotizado. The results indicated that employees perceive with greater intensity the work as a responsibility and as a way of being socially included, and more proportionality in social and financial retribution. They also indicated that manicurists experience with more intensity the characteristics of brutalization, discrimination and demand.

title: Effects of therapeutic and aerobic exercise programs in temporomandibular disorder-associated headaches

description: Abstract Objective To assess the effects of three 8-week exercise programs on the frequency, intensity, and impact of headaches in patients with headache attributed to temporomandibular disorder (TMD). Methodology Thirty-six patients diagnosed with headache attributed to TMD participated in the study and were divided into three groups of 12 patients: a therapeutic exercise program (G1, mean age: 26.3±5.6 years), a therapeutic and aerobic exercise program (G2, mean age: 26.0±4.6 years), and an aerobic exercise program (G3, 25.8±2.94 years). Headache frequency and intensity were evaluated using a headache diary, and the adverse headache impact was evaluated using the Headache Impact Test (HIT-6). The intensity was reported using the numerical pain rating scale. These parameters were evaluated twice at baseline (A01/A02), at the end of the 8-week intervention period (A1), and 8–12 weeks after the end of the intervention (A2). Results At A1, none of the G2 patients reported having headaches, in G1, only two patients reported headaches, and in G3, ten patients reported headache. The headache intensity scores (0.3 [95% CI: -0.401, 1.068]), (0.0 [95% CI: -0.734, 0.734]) and HIT-6 (50.7 [95% CI: 38.008, 63.459]), (49.5 [95% CI: 36.808, 62.259]), significantly decreased in G1 and G2 at A1. At A2 headache intensity scores (0.5 [95% CI: -0.256, 1.256]), (0.0 [95% CI: -0.756, 0.756]) and HIT-6 (55.1 [95% CI: 42.998, 67.268]), (51.7 [95% CI: 39.532, 63.802]) in G1 and G2 haven’t change significantly. The effects obtained immediately after the completion of the intervention programs were maintained until the final follow-up in all groups. Conclusion The programs conducted by G1 (therapeutic exercises) and G2 (therapeutic and aerobic exercise) had significant results at A1 and A2.

title: Hydropower plant in Eastern Amazon and its impacts on the local population’s eating habits

description: Abstract This study assessed the direct impacts of Cachoeira Caldeirão Hydropower Plant (before and during its construction) on the eating habits (fish and wild meat consumption) of the residents in Porto Grande City, Amapá State, Brazil. The study was conducted in 2015, based on a questionnaire for data collection (Sample size = 53) and on comparative analysis for significance (Wilcoxon test, p &lt; 0.05) and correlation (Pearson’s test) assessment. Results suggested significant changes in families’ eating habits. The Wilcoxon test detected three significant variables (p &lt; 0.05): family income, number of species (fish and wild meat consumption) and rate of wild meat consumption per family. Both the Wilcoxon and the Pearson’s correlation tests confirmed two variables (p &lt; 0.05 and r &gt; 0.7): family income versus wild meat consumption before (p value = 0.045; r = - 0.75) and family income versus fish consumption during (p value = 0.0029; r = - 0.83) hydropower plant construction. It can be inferred that the decrease in family fish consumption may be related to changes in the families' eating habits. Changes in diet may have led families to a growing consumption of industrialized and/or ultra-processed foods, very common in geographically isolated Amazon riverside regions with limited access to electricity. Furthermore, families were forced to adapt to a new reality due to environmental changes in their territories.

title: Corn cob reuse in the adsorption of a commercial formulation of glyphosate

description: ABSTRACT In this study a biochar was produced from corn cob (BCA), which was activated with phosphoric acid to verify its potential for removal of herbicide glyphosate (GLF) (commercial formula) in aqueous media. BCA was characterized by X-ray diffraction spectroscopy, infrared spectroscopy, sorption and desorption of N2, scanning electron microscope, and zero charge potential. Kinetic results of adsorption were adjusted to pseudo-first and pseudo-second order reactions. The adsorption process was studied to verify if it followed Freundlich and Langmuir isotherms, and the thermodynamic parameter was calculated for 23 oC, 43 cC and 63 oC. The results showed that adsorption of GLF on BCA depended on temperature, adsorbent mass, and pH. The best results were obtained for the temperature of 63 oC with 0.25 g de GLF and pH = 7.0, conditions that presented 62.3% of GLF removal and low adsorption capacity (2.67 mg. g−1). That was probably due to the porous nature of BCA and co-adsorption of other constituents that were present in the commercial formula of GLF. The adsorption kinetics was represented by the model of pseudo-second order and considered fast, taking 15 min to reach 98% of the maximum adsorption capacity. The isotherm data were well represented by the Freundlich model. Finally, the thermodynamic study demonstrated that the adsorption of GLF is of endothermic nature (ΔHº &gt; 0) and endergonic (ΔGº &gt; 0). The results confirmed that BCA from corn cob is an adsorbent capable of removing GLF (commercial formula) from aqueous media. However, the endothermic nature of the process can compromise its performance in water treatment processes.

title: Mapping the Available Water Capacity in tropical climate soils for soybean (Glycine max) cultivation in the state of Tocantins-Brazil

description: Abstract Brazilian soybean has undergone considerable economic growth. Its production depends on the demand for some inputs. One of these inputs is the soil water supply, which can be made artificially or obtained by natural rainfall. Knowledge of available water capacity (AWC), which depends on total water availability (TWA), is poorly accessible and difficult to measure in the field. This study aimed to map the AWC of the state of Tocantins, based on pedotransfer functions (PTFs), to evaluate the water availability of the soils of the microregions of that state. We used the Arya and Paris model, aided by a computer program, Qualisolo, made by Embrapa Instrumentação. One hundred fifty-seven tropical soil samples were extracted from the Embrapa Solos portal. Preliminarily, the soil water retention curve (SWRC) was obtained and, subsequently, the TWA and AWC for this oilseed were estimated. Multiple linear regressions show the correlation between TWA and clay (CL), Silt (ST) and total sand (TS) contents. The correlation established was TWA = 3.2993 - 0.0028TS - 0.0034CL. This main conclusion reflects a fruitful AWC for decision-making by the soybean agribusiness and exposes the regional weaknesses for this crop under a rainfed regime in some regions of Tocantins. We could observe that, in terms of water availability, agribusiness is a potential threat to the environment protection area (APA) of the Ilha do Bananal/Cantão, Formoso River microregion.

title: GENERALIZED ADDITIVE MODEL FOR COUNT TIME SERIES: AN APPLICATION TO QUANTIFY THE IMPACT OF AIR POLLUTANTS ON HUMAN HEALTH

description: ABSTRACT The generalized additive model (GAM) has been used in many epidemiological studies where frequently the response variable is a nonnegative integer-valued time series. However, GAM assume that the observations are independent, which is generally not the case in time series. In this paper, an autoregressive moving average (ARMA) component is incorporated to the GAM. The resulting GAM-ARMA model is based on the generalized linear autoregressive moving average (GLARMA) model where some linear components are replaced by natural splines. Numerical simulations are presented and show that the ARMA component influences the estimation. In a real data analysis of the effects of air pollution on respiratory disease in the metropolitan area of Belo Horizonte, Brazil, it is shown that the proposed model presents a better fit when compared to the classical GAM approach, that does not take into account the autocorrelation of the data.

title: Intervening factors in the costs of fluoridation in water supply systems: a case study in seven population sizes

description: ABSTRACT The aim of this study was to analyze the costs of fluoridation in water supply systems of different population sizes. A case study was carried out comprising cities in the state of Espírito Santo, Brazil. The costs of initial installation, the chemical product, the operation of the system, and the control of fluoride levels between the years 2012 and 2017 were considered. The annual per capita cost of the treatment was calculated to estimate the fluoridation weight concerning the total expenses. The fluoridation annual per capita cost ranged from R$ 20.14 (US$ 7.23) in towns with less than two thousand inhabitants to R$ 0.39 (US$ 0.14) in cities with a population of approximately 520 thousand inhabitants. In systems that supply up to 30 thousand inhabitants, the running cost was responsible for most of the expenses, ranging from 98.2 to 84%. For cities with 520 thousand inhabitants, the costs with the chemical product corresponded to 74.7% of the expenses. Compared with the total treatment cost, the water fluoridation cost ranged from 0.2 to 0.6% for population sizes of 30 thousand inhabitants or more and varied from 1.3 to 7.3% for towns with less than 10 thousand inhabitants. Considering that the decision-making process is complex in the field of public policies, and decision-makers suffer multiple influences as for different policy alternatives, knowing the implications of population size for costs is essential for informed decision-making.

title: Willingness to pay for short- and long-acting contraceptives among female adolescents and their parents in Brazil:a pilot study

description: ABSTRACT Objective To evaluate willingness to pay for short- and long-acting reversible contraceptive methods among female Brazilian adolescents and their parents, as well as their perspective on using such methods. Methods This is a cross-sectional study of female adolescents aged 13 to 19 years and their parents. We surveyed to estimate their willingness to pay for contraceptive methods. The values are expressed as mean±standard deviation in Brazilian reals (R$). Spearman correlation was employed for socioeconomic status of parents, age of adolescents and their standpoints. The methods types and adolescent and parent perspectives were analyzed by the test χ2. To determine an agreement between pairs and their willingness to pay, we used the Bland-Altman plot. Results A total of 165 surveys were collected. Short-acting method was significantly more acceptable to pay than the long-action method, by both parents and their daughters. Parents and their daughters are willing to pay out-of-pocket R$ 52,25±22,48 and R$ 51,63±21,24 for short-acting reversible contraception method, and R$ 176,83±130,34 and R$ 174,83±143,64, for long-acting method, respectively. Bland-Altman analysis indicated an agreement on both perspectives and the price they are willing to pay for each contraceptive method. Conclusion Parents and adolescent daughters are more willing to pay for short-acting methods. We showed an agreement between the parent and the daughter for the values paid for each method.
