Redes do cuidado : etnografia de aparatos de gestão intersetorial para usuários de drogas
(Universidade Federal de São Carlos, 2015-10-22) Martinez, Mariana Medina; Villela, Jorge Luiz Mattar; https://lattes.cnpq.br/8301325600502054; https://lattes.cnpq.br/9126534946585241
This research presents an ethnography of care’s network. I describe the mode of operation of an intersectoral management for drug users, as from a fieldwork in public health equipment in São Bernardo do Campo (SP). The construction of networks for reception and support care (acolhimento e cuidado), appointment (encaminhamento) and treatment for this targeted public is the empirical question that guides this research. The ambiguous figure of drug user (both patient and defaulter) resonates in the public policies for this population. For this reason, the networks both care as well as enclose these subjects at the same time. The ethnography of network in the health sector explores the challenges and dilemmas that these intersectoral management apparatus evoke. I present the issues that revolve around the network’s organizational model that is formulated by standardization of policies and the universalization of principles, but in practical terms they are invented according to the occasions. I also raised the dilemmas of how workers throw themselves on the challenge of tying partnerships, doing maintenance, seeing the size of the network, tracking the movement of people, information and documents, and planning their growth in the territories. Such developments matches the dilemmas of an assistance project that aims to take care of people in freedom, accomplishing the democratic and humanistic precepts, but intends to monitor the movements and pursue many traces.
Diferentes estratégias espectroanalíticas para a determinação de metais em cosméticos
(Universidade Federal de São Carlos, 2015-10-22) Batista, Érica Ferreira; Pereira Filho, Edenir Rodrigues; https://lattes.cnpq.br/3394181280355442; https://lattes.cnpq.br/3830711529545975
In this work, it was developed a procedure for the determination of metals in cosmetics, employing the techniques ICP OES, GF AAS, LIBS and LA-ICP OES; in addition, it was explored the potential of chemometric tools. For the determination of Cd, Co, Cr, Cu and Ni by ICP OES and Pb by GF AAS in eyeshadow and lipstick samples, it was developed a sample preparation method using diluted nitric acid and a hot block. For the optimization of chemical parameters of sample preparation and operating parameters of ICP OES, it was used factorial design and for data analysis and selection of the best working conditions, the desirability functions were employed. In total, it was analyzed 30 samples of cosmetics (21 eyeshadow and 9 lipstick), of different colors, brands and from different countries (Brazil, USA and China). These samples were analyzed in triplicate and with standard addition to perform the recovery calculations. The analyzed samples showed concentration of Cd and Pb within the limits set by the laws, however, 7 eyeshadow samples had concentration of Cr and Ni above than 5 g g-1. In the case of lipstick samples, all values were below this safe limit. All samples analyzed by ICP OES and GF AAS were also analyzed without sample pretreatment by LIBS. The values obtained in the quantitative analysis were employed in the development of supervised classification models such as the KNN and SIMCA. For the obtainment of these models, data of children´s cosmetics samples were included. The classes considered in the models were: below and above the legislation, with a limit set at 5 mg kg-1, according to the recommendations in the literature. In addition to analysis of eyeshadow and lipstick samples, it was explored the potential of the techniques LIBS and LA-ICP OES along with chemometric tools for exploratory analysis of sunscreen samples. The results were obtained for three different equipment (two LIBS and one LA-ICP OES), and several models employing principal component analysis (PCA) were generated. The signals profile of Al, Ni, Ti, and Zn were analyzed and the results obtained between the three equipment were similar.
