    Administração Pública E Prestação Jurisdicional: O Papel Da Conciliação Na Justiça Do Trabalho

    It is understood that the judicial organizational culture in Brazil should be guided by such items as transparency, impersonality, speed and, fundamentally, the promotion of social pacification and the exercise of citizenship. These items are essential for a strategic administration, necessary for the alignment of the Judiciary Power to the public administration management. The long process of proceedings in judicial forums is repeatedly pointed out as one of the greatest obstacles to the effectiveness of justice in Brazil. Established as a public policy by the National Council of Justice (NCJ), consensual methods of conflict resolution are one of the pillars of the Judiciary Power plan, aimed at meeting the longing of society for speed in the jurisdictional provision. Therefore, it was sought to identify the current model of managerial control and organizational culture installed within the scope of the Regional Labor Court of the 2nd Region and its consonance with the guidelines of the National Council of Justice and with the other public policies of the central organs of federal public administration. For this reason, the Institutional Strategic Plan (ISP) of the organization and its relationship with the Situational Strategic Planning (SSP), admitted in this work as the most appropriate for the public administration, were also analyzed, using contemporary models of the current literature as parameters for the formulation of the thesis. Identifying, further, that the conciliation, used as a consensus method of conflict resolution, is an important instrument of expeditious and effective judicial service, this research was mainly aimed at verifying the indexes of full compliance with agreements made within the scope of the Judicial Center of Conflict Resolution of the Labor Forum of the East Zone of the city of São Paulo, as well as to create performance indicators, supported by the management follow-up in 208 different processes, chosen at random from amongst those who began their process by means of a conciliatory session designation, parallel to the traditional way of proceeding, to the execution or filing phase, in order to compile comparative data that showed a managerial perspective in both forms, using data from the National Council of Justice as parameters for the formulation of the analysis Results and in monitoring the fulfillment of its institutional mission.

    Estudo Das Propriedades Termomecânicas E Características Morfológicas De Grafites Sintéticos De Uso Aeroespacial

    In a rocket motor with solid propulsion, the energy of the combustion reaction of chemical propellant at high pressure results in the generation of gases at temperatures in the order of 2700 °C. These extreme operating conditions lead to the search for materials with adequate mechanical characteristics around 2500 °C, good heat conductors and which are little affected by severe thermal shock. In compliance with these strict requirements, one of the materials used is the synthetic graphite. Considering that there is no available direct correlation in the literature among morphological, thermal and mechanical characteristics of synthetic graphites for space use, the present work has the objective of characterizing three types of synthetic graphites by means of mechanical tests (tensile and compression strength), physical (porosity, density and of thermal expansion coefficients and thermal diffusivity measurements) and morphological (optical microscopy) analyses. The results obtained in morphological analyses show that the studied samples are anisotropic carbon materials with very different optical textures. The analysis of the surface porosity shows values between ~2.3 and 30%, depending on the type of graphite and the radial or longitudinal position of withdrawal of the specimen in the graphite billet. The apparent density varied between 1.72 and 1.79 g/cm3. The density values obtained by helium pycnometry ranged from 2.05 to 2.14 g/cm3. These results indicate that the samples present different volumes of open pores. BET and BJH analyses confirm that the samples present a micropores distribution with different shapes. Measurements of coefficient of thermal expansion (3.58-4.64x10-6 oC-1, in the range 25-500 oC) and thermal diffusivity (~ 14-26x10-6 m2/s at 850 oC) show the influence of grain direction and also indicate that one of the samples of graphite was probably obtained by uniaxial pressing and not by extrusion. The correlation of tensile (~10 to 26 MPa) and compression (~30 to 76 MPa) strength results as a function of surface porosity shows that these properties are affected by the porosity level in a non-linear manner. The results show that the evaluation of the optical textures and the distribution of surface pores and also the tensile and compression strength are priority requirements in the selection of synthetic graphite of space use.
