Supervision of Community Health Agents in the Family Health Strategy: the perspective of nurses

Objective Analyzing the conceptions of supervision of nurses in the Family Health Strategy (ESF - Estratégia Saúde da Família) in relation to community health workers (ACS – Agente Comunitário de Saúde), taking for reference the work process and the power relations. Method A qualitative study, in which 18 interviews were carried out with nurses from the ESF in the countryside of the state of Goiás. Following transcription, the data were subjected to thematic content analysis and the following categories were identified: Supervision with that sees it all and Supervision is participating and working together. Results Among the findings, it is clear the character of control and monitoring that is carried out primarily through printed instruments and home visits, which constitute vertical and impositive relations, and suffer influence of the local health management. Another finding is the supervision as acting together and with the educational perspective. Conclusion The supervision carried out does not provide the changes intended by the ESF.

Synthesis, characterization and thermal behaviour of solid-state compounds of benzoates with some bivalent transition metal ions

Solid-state MBz compounds, where M stands for bivalent Mn, Fe, Co, Ni, Cu and Zn and Bz is benzoate, have been synthesized. Simultaneous thermogravimetry and differential thermal analysis (TG-DTA), differential scanning calorimetry (DSC), infrared spectroscopy and complexometry were used to characterize and to study the thermal behaviour of these compounds. The procedure used in the preparation of the compounds via reaction of basic carbonates with benzoic acid is not efficient in eliminating excess acid. However the TG-DTA curves permitted to verify that the binary compounds can be obtained by thermosynthesis, because the benzoic acid can be eliminated before the thermal decomposition of these compounds. The results led to information about the composition, dehydration, thermal stability, thermal decomposition and structure of the isolated compounds. On heating, these compounds decompose in two (Mn, Co, Ni, Zn) or three (Fe, Cu) steps with formation of the respective oxide (Mn3O4, Fe2O3, Co3O4, NiO, CuO and ZnO) as final residue. The theoretical and experimental spectroscopic studies suggest a covalent bidentate bond between ligand and metallic center.

The results are discussed mainly taking into account the linear dependence between the activation energy and the pre exponential factor, where was verified the effect of kinetic compensation (KCE) and possible linear relations between the dehydrations steps of these compounds.
