In the last years, some expressions such enterprises and supplier cooperation relationship have became used. The main objective of those relationships is to improve the competitiveness of the organizations through costs reductions and quality / flexibility improvements. On this context, this work presents and analyzes, through a case study method, a new form of purchasing management in a stationery products company that is the Brazilian leader of its segment. The enterprise looks for a higher organizational strategy alignment in order to guarantee its leadership. To achieve this aim, the enterprise changed its manufacturing management framework, initially based just on cost and quality issues, to a more responsive paradigm. The work presents all changes inside the purchasing department and the consequent effects to other areas directly related to the acquisition process. A theoretical and empiric analyses is presented, where the research, based on theory, identify the main manufacturing management strategic paradigms and how they can be related to the state of art in purchasing management. Following, the work presents the purchasing management framework of the organization in two different moments: from 1998 to 2001 and after 2002. It will be possible to realize how strategic the purchasing management can become to an organization. The results can be useful to enterprises with the same characteristics or inserted in the same process of change.
Elementos para a formulação de uma psicossomática psicanalítica

From the link between the works of Freud, Ferenczi and Groddeck, this study attempts to show that psychoanalysis, since their first developments, provides evidence for the formulation of a psychoanalytic psychosomatic. In the first chapter, when we approach psychoanalytic concepts that are in the intersection between the psychic and somatic, we present evidences suggesting that somatic changes that affect somatic functions and/or structures are produced when, under impact of a traumatic situation, added by the insufficiency of the specific action, the discharge of the affection occurs of a totally unconscious way, running a cumulative excitement that found no other way of expression. This means of discharge, which is based upon the acting, not on the word, can come up from phylogenesis after the failure of the ontogenesis to equip the individual with more consistent reactions to him face limit-situations of reality. Prevented from acting against the object, the natural aggressiveness -inherent to the instincts of preservation of the species- acts in the way to disrupt the psychic functioning or, if it is sufficiently protected by the cleavage of the ego, disorganizing the somatic structures. On that regression beyond the psychic limits, selfdestructiveness, remnant of the original masochism, expressed a force even more basic in the formation of living being, as sought to show in the second chapter. Identified by Freud at both the psychological level as in the somatic level, the death drive extends the roots of unconscious to the biological level, considering the existence of an undifferentiated region between soma and psyche, where the variations of a level impact on the other. This hypothesis is supported: (1) by Ferenczi, who introduced changes in analytical technique with the aim of promoting a regression able to access content from traumatic experiences, and reached archaic and undifferentiated contents, that remains detained in the body as a memory without words, at the margin of language and the further development of the ego, producing psychical and somatic suffering, (2) by the location of the It at the psychic apparatus, connected directly with the somatic forces. By tracing the origin of It until the thought of Groddeck, in the third chapter, we find an unconscious-It that precedes the psychosomatic existence. For Groddeck, the lack of symbolic significance of organic diseases are due to the split between soma and psyche inherent at the explanatory model, for which the disease and the sickness organs are not seen as symbols that can be decoded and resized from the symbolic nature of unconscious. Finally, we show that, in despite the work of Freud provides explanations for the psychosomatic phenomenon in a psychoanalytic perspective it is Groddeck and Ferenczi that provide the clinical features that allow rescuing the psychosomatic phenomenon to become synonymous with lack of symbolization. Despite Freud have remained away of this issue and skeptical about the resolution of the psychosomatic disease through analysis, some of his assertions in his last years show that the creator of metapsychology not remained totally unrelated to that possibility.
Estrutura e propriedade fotoluminescente do titanato de bário e cálcio obtido pelo método de polimerização de complexos (MPC)

The synthesis and characterization of Ba1-xCaxTiO3 (BCT) for x = 5; 10; 15; 20; 40 e 80 % mol that crystallizes in a perovisquita structure were studied in this work. The BCT material was synthesized by CPM which allows obtaining structurally ordered and disordered powders. The effect of the calcium concentration was analyzed for the structurally ordered and disordered materials. The powders were crystallized at several temperatures ranging from 400 to 1200 °C for different times. The obtained materials were characterized by X-ray diffraction (XRD), Raman spectroscopy, differential scanning calorimetry (DSC) and X-ray Absorption Near Edge Structure (XANES) and photoluminescent emission (PL). These techniques allowed to observe the evolution of the phases as well as the structural disorder of the samples. XRD results indicated that up to 20 % mol of calcium, there is formation of a solid solution with Ca2+ ion occupying the Ba2+ site in the of the BaTiO3 crystalline network. It was verified that the BCT ordered phase was obtained after calcining at 600 °C by 2 h. The presence of an intermediate oxicarbonate barium phase in temperatures below of the tetragonal BCT crystallization. The luminescent property of structurally ordered and disordered BCT powders were studied at room temperature, using two excitation wavelengths: 350,7 nm and 488,0 nm. Structurally disordered BCT present broad PL band when excited by both of wavelengths. The powders annealed at 500 oC displays the most significant PL intensity. It was verified that with the increase of the calcium concentration, the maximum of the photoluminescent emission curve tends to laser wavelength energy. XANES spectra showed in the disordered powders the coexistence of sixfold and fivefold titanium coordination. A correlation between the coexistence of this two types of coordination for the titanium atoms and PL was proposed.
