RESUMOTrata-se de um estudo exploratório e descritivo, de natureza quantitativa, com o objetivo de identificar o nível de conhecimento da comunidade de Brasilit, acerca dos riscos e benefícios do uso de plantas medicinais e fitoterápicos (forma de obtenção, acondicionamento e preparação de remédios caseiros), visando a evitar o uso inadequado e a automedicação por esta população. A amostra será definida por critérios não probabilísticos constituída por homens e mulheres residentes na referida comunidade na cidade do Recife, que desejem participar espontaneamente desta pesquisa. Para a coleta de dados será utilizado um questionário que em seguida será iniciado o processo de análise. Para isto, os dados serão tabulados e receberão tratamento estatístico elementar, sendo agrupados e apresentados em gráficos, tabelas e quadros cuja freqüência será demonstrada em valores percentuais. Palavras-chave: Conhecimento; Risco; Plantas medicinais; Fitoterápicos.ABSTRACTExploratory and descriptive study, of quantitative boarding, aiming at identifying the knowledge level of the Brasilit community, concerning the risks and benefits of the use of medicinal plants and fitotherapics (attainment form, preservation and preparation of remedies caretakers), aiming at preventing the inadequate use and the self-medication for this population. The sample will be defined by not probabilistic criteria constituted by men and women resident in the related community, whom they desire to participate spontaneous of this research. For the collection of data a questionnaire will be used that after that will be initiated the analysis process. For this, the data will be tabulated and will receive statistical treatment elementary, being grouped and presented in graphs, tables and pictures whose frequency will be demonstrated in percentile values.

The Operation Modes of E/E/PE System and Their Influence on Determining and Verifying the Safety Integrity Level The standard PN-EN 61508 introduces some probabilistic criteria for the E/E/PE systems that can operate in different modes of operation, which are related to the safety integrity level (SIL). For the control and protection systems, operating in a low demand mode, the criterion is the average probability of dangerous failure on demand PFDavg. In case of systems working in a continuous mode of operation or high demand, the criterion is probability of dangerous failure per hour PFH. In practice, the E/E/PE systems implement many safety-related functions (SRFs), which have different requirements for high and low demands. Thus, there is the problem with choosing proper probabilistic criterion for determining required SIL for a safety-related function to be implemented by these systems as well as in the process of quantitative verification of SIL for considered architectures.

According to Allen and Pardo, the field of evidence law has experienced a revolution -in Kuhn's sense- from probabilism to explanationism, which they identify with the relative plausibility theory. The explanationist revolution, argue Allen and Pardo, has placed explanationist -rather than probabilistic criteria- at the core of the fact-finding process and, in contrast to probabilism, has advanced a comparative understanding of the theory of legal proof. This paper develops an alternative interpretation of the explanationist revolution in evidence law. First, it elaborates on the concept of legal revolution and argues that it involves a kind of shift that is best characterized as a Hacking -rather than a Kuhnean- type of revolution and, thus, as an ‘emplacement’ instead of a ‘replacement’ revolution. Second, it claims that the shift from probabilism to explanationism involves a deep -genuinely revolutionary- change in the conception of rationality that is taken to govern the processes of evidence and legal proof. Other differences between probabilistim and explanationism, such as those mentioned by Allen and Pardo, are not central to the revolutionary shift, but rather emanate from this basic distinction. Last, it argues that the explanationist paradigm embraces, but cannot be reduced to, the relative plausibility theory; the identification of explanationism with the relative plausibility theory occludes the richness and possibilities harboured by the new, explanationist, paradigm.

The hazard of permanent ground displacements/deformations can challenge the safety of the nuclear power plants. Increasing knowledge of the hazard and development of methods for structure–fault–displacement interaction motivates the designing of nuclear power plants for permanent ground displacement instead of abandoning the sites that could be affected by this kind of hazard. For the design basis, permanent ground displacement should be defined at the hazard level that complies with the probabilistic criteria for accounting for the natural hazards in the design that also ensure compliance with probabilistic safety criteria. In this paper, a procedure is proposed for the definition of the design basis permanent ground displacement that is based on the deaggregation of seismic design basis hazard. The definition of the displacement for the margin evaluation is also proposed. The feasibility of safe design is also demonstrated for the proposed definition of design basis hazard via qualitative judgement on the sensitivity of the structures, systems and components ensuring the fundamental safety functions with respect to the permanent ground displacement that is supported by existing case studies.

A calculation tool has been developed for determining tidal windows for deep-drafted ships approaching and leaving the Belgian harbors according to probabilistic criteria. The calculations are based on a database containing response functions for the vertical motions in waves and squat data for a selection of representative ships. The database contains both results of model tests carried out in the Towing tank for maneuvers in shallow water – co-operation Flanders Hydraulics Research & Ghent University in Antwerp (Belgium), as well as calculated values. During the experiments, draft, trim, under keel clearance (7 to 20% of draft) and speed have been varied. The tests were performed in regular waves with lengths which are small compared to ship length, and in wave spectra that are typical for the Belgian coastal area. For given input data (ship characteristics, speed, tide, directional wave spectra, bottom, trajectory, current, departure time), the tool calculates the probability of bottom touch during the transit, so that a tidal window can be determined. Other restrictions, such as penetration into fluid mud layers and current, are taken into account as well.
