The Challenges of Psychology at Work in Mental Health: the drugs issue.

This article aims to show that the challenges of psychology in working with mental health in the field of drugs is traversed by both the conceptions molded by biopolitical forces (FOUCAULT) as the decadence of modern democracy (AGAMBEN), and visible features in the current treatment given in Brazil to issue of smoking (SILVA), as well as urbanistic projects such as the case of Luz district in São Paulo (LEITE & CASTRO). In this sense, it leads us to question about what is prohibited, about who actually suffers the punishment, in short, about what do we really take care when we take into account the Unheimlich (FREUD) and other social interdicts (BATAILLE).

Cartographic notes on the work in the Family Health Strategy: relationships between workers and the population

The objective of this intervention study was to map instituted and instituting movements present in the work of the Family Health Strategy in the development of their care practices. The theoretical framework is based on institutional analysis, using the schizoanalytic approach. Group meetings were carried out with the staff to discuss how they provided collective care in continuing health education. The study subjects were professionals from the team and students who were engaged in academic activity in the service. The average attendance was twelve people per meeting, and there were a total of eight meetings from March to July 2010. Data were grouped into two immanent strata: the relationships of the team and the relationship with clients. The strata point to the intersection of education and legal institutions and the social and technical division of labor. Collective thinking in groups appeared to be effective in denaturalizing established processes and interrogating places, knowledge and practices.

Three time-based scale formulations for the two-stage lot sizing and scheduling in process industries

In this paper, we propose three novel mathematical models for the two-stage lot-sizing and scheduling problems present in many process industries. The problem shares a continuous or quasi-continuous production feature upstream and a discrete manufacturing feature downstream, which must be synchronized. Different time-based scale representations are discussed. The first formulation encompasses a discrete-time representation. The second one is a hybrid continuous-discrete model. The last formulation is based on a continuous-time model representation. Computational tests with state-of-the-art MIP solver show that the discrete-time representation provides better feasible solutions in short running time. On the other hand, the hybrid model achieves better solutions for longer computational times and was able to prove optimality more often. The continuous-type model is the most flexible of the three for incorporating additional operational requirements, at a cost of having the worst computational performance.

Professional competences of nurse to work in Intensive Care Units: an integrative review

This study aimed to identify and analyze nurses' competences to work at Intensive Care Units-ICU. An integrative review method was used, and data were collected in LILACS, SciELO and BDENF, from August to October 2010. Ten articles were identified, published in the last 12 years. Data grouping permitted the construction of thematic units related to nurses' competences: nursing care management, high-complexity nursing care delivery, decision making, leadership, communication, continuing/permanent education, human resource management, material resource management. The professional competences identified can support the outline of guidelines to constitute the profile of nursing working in intensive care units and drive/mobilize the improvement of nursing care practices.

Quantitative risk analysis as a tool in process design

La Quantitative Risk Analysis costituisce un valido strumento per la determinazione del rischio associato ad un’installazione industriale e per la successiva attuazione di piani di emergenza. Tuttavia, la sua applicazione nella progettazione di un lay-out richiede la scelta di un criterio in grado di valutare quale sia la disposizione ottimale al fine di minimizzare il rischio. In tal senso, le numerose procedure esistenti, sebbene efficaci, risultano piuttosto faticose e time-consuming. Nel presente lavoro viene dunque proposto un criterio semplice ed oggettivo per comparare i risultati di QRA applicate a differenti designs. Valutando l’area racchiusa nelle curve iso-rischio, vengono confrontate dapprima le metodologie esistenti per lo studio dell’effetto domino, e successivamente, viene applicata al caso di serbatoi in pressione una procedura integrata di Quantitative Risk Domino Assessment. I risultati ottenuti dimostrano chiaramente come sia possibile ridurre notevolmente il rischio di un’attività industriale agendo sulla disposizione delle apparecchiature, con l’obiettivo di limitare gli effetti di possibili scenari accidentali.
