    The main purpose of this work is the study of human reliability using the THERP (Technique for Human Error Prediction) and ATHEANA methods (A Technique for Human Error Analysis), and some tables and also, from case studies presented on the THERP Handbook to develop a qualitative and quantitative study of nuclear power plant accident. This accident occurred in the TMI (Three Mile Island Unit 2) power plant, PWR type plant, on March 28th, 1979. The accident analysis has revealed a series of incorrect actions, which resulted in the Unit 2 shut down and permanent loss of the reactor. This study also aims at enhancing the understanding of the THERP method and ATHEANA, and of its practical applications. In addition, it is possible to understand the influence of plant operational status on human failures and of these on equipment of a system, in this case, a nuclear power plant. (author)

  2. Evaluation of ATHEANA methodology a second generation human reliability analysis

    International Nuclear Information System (INIS)

    Incidents and accidents at nuclear power plants (NPP) have been and always will be considered as undesired occurrences. Human error (REASON, 1990) is probably the major contributor to serious accidents as those that occurred at Three Mile Island NPP, Unit 2 (TMI-2), in 1979, and Chernobyl, Unit 4, in 1986, and (AEOD/E95-01, 1995 at others NPPs. Reviews and analysis of those accidents and others near-misses have shown operators performing actions that are not required for the accident response and, in fact, worsen the plant's condition. This action, where a person does something that it's not supposed to do, believing that it was the right thing to do, resulting in changes in the plant that may be worse than if he had done nothing, is called Error of Commission (EOC). These inappropriate actions are rightly affected (NUREG-1624, Rev.1, 2000) by the off-normal context (i.e., the combination of plant conditions and performance shaping factors) of the event scenario that virtually forces the operator to fail. Considering that this kind of human intervention could be an important failure mode and precursor to more serious events, aggravated by the fact that actual probabilistic risk assessment (PRA), does not consider this kind of error, a new methodology (NUREG-1624, Rev.1, 2000) was developed of Human Reliability Analysis (HRA), called 'A Technique for Human Event Analysis' (ATHEANA). ATHEANA is a multidisciplinary second-generation HRA method and provides an HRA quantification process and PRA modeling interface that can accommodate and represent human performance in real nuclear power plant accidents. This paper presents this new methodology in order to identified its weak and strong points, to evaluate its advantages and disadvantages and its benefits to safety, and finally, to analyze its application to Angra NPP.

  6. ATHEANA: A Technique for Human Error Analysis: An Overview of Its Methodological Basis

    International Nuclear Information System (INIS)

    The U.S. NRC has developed a new human reliability analysis (HRA) method, called A Technique for Human Event Analysis (ATHEANA), to provide a way of modeling the so-called 'errors of commission' - that is, situations in which operators terminate or disable engineered safety features (ESFs) or similar equipment during accident conditions, thereby putting the plant at an increased risk of core damage. In its reviews of operational events, NRC has found that these errors of commission occur with a relatively high frequency (as high as 2 or 3 per year), but are noticeably missing from the scope of most current probabilistic risk assessments (PRAs). This new method was developed through a formalized approach that describes what can occur when operators behave rationally but have inadequate knowledge or poor judgement. In particular, the method is based on models of decision-making and response planning that have been used extensively in the aviation field, and on the analysis of major accidents in both the nuclear and non-nuclear fields. Other papers at this conference present summaries of these event analyses in both the nuclear and non-nuclear fields. This paper presents an overview of ATHEANA and summarizes how the method structures the analysis of operationally significant events, and helps HRA analysts identify and model potentially risk-significant errors of commission in plant PRAs.

  8. Philosophy of ATHEANA

    International Nuclear Information System (INIS)

    ATHEANA, a second-generation Human Reliability Analysis (HRA) method integrates advances in psychology with engineering, human factors, and Probabilistic Risk Analysis (PRA) disciplines to provide an HRA quantification process and PRA modeling interface that can accommodate and represent human performance in real nuclear power plant events. The method uses the characteristics of serious accidents identified through retrospective analysis of serious operational events to set priorities in a search process for significant human failure events, unsafe acts, and error-forcing context (unfavorable plant conditions combined with negative performance-shaping factors). ATHEANA has been tested in a demonstration project at an operating pressurized water reactor

  9. Human events reference for ATHEANA (HERA) database description and preliminary user's manual

    International Nuclear Information System (INIS)

    The Technique for Human Error Analysis (ATHEANA) is a newly developed human reliability analysis (HRA) methodology that aims to facilitate better representation and integration of human performance into probabilistic risk assessment (PRA) modeling and quantification by analyzing risk-significant operating experience in the context of existing behavioral science models. The fundamental premise of ATHEANA is that error-forcing contexts (EFCs), which refer to combinations of equipment/material conditions and performance shaping factors (PSFs), set up or create the conditions under which unsafe actions (UAs) can occur. Because ATHEANA relies heavily on the analysis of operational events that have already occurred as a mechanism for generating creative thinking about possible EFCs, a database, called the Human Events Reference for ATHEANA (HERA), has been developed to support the methodology. This report documents the initial development efforts for HERA

  13. The action characterization matrix: A link between HERA (Human Events Reference for ATHEANA) and ATHEANA (a technique for human error analysis)

    International Nuclear Information System (INIS)

    The Technique for Human Error Analysis (ATHEANA) is a newly developed human reliability analysis (HRA) methodology that aims to facilitate better representation and integration of human performance into probabilistic risk assessment (PRA) modeling and quantification by analyzing risk-significant operating experience in the context of existing behavior science models. The fundamental premise of ATHEANA is that error-forcing contexts (EFCs), which refer to combinations of equipment/material conditions and performance shaping factors (PSFs), set up or create the conditions under which unsafe actions (UAs) can occur. ATHEANA is being developed in the context of nuclear power plant (NPP) PRAs, and much of the language used to describe the method and provide examples of its application are specific to that industry. Because ATHEANA relies heavily on the analysis of operational events that have already occurred as a mechanism for generating creative thinking about possible EFCs, a database, called the Human Events Reference for ATHEANA (HERA), has been developed to support the methodology. Los Alamos National Laboratory's (LANL) Human Factors Group has recently joined the ATHEANA project team; LANL is responsible for further developing the database structure and for analyzing additional exemplar operational events for entry into the database. The Action Characterization Matrix (ACM) is conceived as a bridge between the HERA database structure and ATHEANA. Specifically, the ACM allows each unsafe action or human failure event to be characterized according to its representation along each of six different dimensions: system status, initiator status, unsafe action mechanism, information processing stage, equipment/material conditions, and performance shaping factors. This report describes the development of the ACM and provides details on the structure and content of its dimensions

  14. Relevant Assumptions at the basis of the UMAE uncertainty methodology

    International Nuclear Information System (INIS)

    This paper deals with preliminary results of the application of UMAE (Uncertainty Methodology based upon Accuracy Extrapolation) uncertainty procedure to the Uncertainty Methods Study (UMS) proposed by OECD/CSNI. The UMAE allows the evaluation of the error made by a system thermalhydraulic code when predicting a nuclear power plant transient scenario. The UMS is an international activity proposed with the aim of comparing the basic assumptions and the results produced by five uncertainty methodologies. The transient adopted as the object of the analysis is a small break LOCA performed in the Japanese Large Scale Test Facility (LSTF) previously adopted for International Standard Problem 26. The analysis of ten experiments performed in differently scaled facilities have been used as a basis for extrapolation of the accuracy. The hypothesis at the basis of the methodology and the main steps are discussed. (author)

  15. Qualification of the UMAE-SEFT uncertainty methodology

    International Nuclear Information System (INIS)

    In this paper, an attempt will be made to quality UMAE-SETF uncertainty methodology that uses a non-homogeneous set of experimental data for a selected phenomenon from separate effects and integral facility tests, for obtaining the uncertainty in the code prediction of a single phenomenon. The critical heat flux (CHF) phenomenon from the validation matrices has been chosen as the example case. The qualification process of the methodology is developed taking as reference plant the LSTF facility. The comparison between the uncertainty calculated and the real error given by the code calculation permit to judge the capabilities of the methodology in the prediction of a behaviour of the code in the representation of the CHF phenomenon, and can give a useful indication in the suitability of the methodology in the uncertainty calculation of the same phenomenon during an accident scenario in a nuclear power plant. The results obtained show that error done by the code in the representation of CHF phenomenon is included in the range of the uncertainty predicted by the methodology, that is estimated in plus or minus 216 K.

  16. Analysis of operational events by ATHEANA framework for human factor modelling

    International Nuclear Information System (INIS)

    In the area of human reliability assessment, the experts recognise the fact that the current methods have not represented correctly the role of human in prevention, initiating and mitigating the accidents in nuclear power plants. The nature of this deficiency appears because the current methods used in modelling of human factor have not taken into account the human performance and reliability such as it has been observed in the operational events. ATHEANA - A Technique for Human Error ANAlysis - is a new methodology for human analysis that has included the specific data of operational events and also psychological models for human behaviour. This method has included new elements such as the unsafe action and error mechanisms. In this paper we present the application of ATHEANA framework in the analysis of operational events that appeared in different nuclear power plants during 1979-2002. The analysis of operational events has consisted of: - identification of the unsafe actions; - including the unsafe actions into a category, omission ar commission; - establishing the type of error corresponding to the unsafe action: slip, lapse, mistake and circumvention; - establishing the influence of performance by shaping the factors and some corrective actions.

  17. Field Test of ATHEANA (A Technique for Human Event Analysis) in Pressurised Thermal Shock Probabilistic Risk Assessments

    International Nuclear Information System (INIS)

    The U.S. Nuclear Regulatory Commission (USNRC) is currently developing the technical basis for potentially modifying the Pressurised Thermal Shock (PTS) screening criteria specified in Title 10 Part 50.61 of the U.S. Code of Federal Regulations. As part of this effort, PTS probabilistic risk assessments (PRAs) are being performed by the USNRC and its contractors, for two U.S. nuclear power plants, with assistance by the respective utilities. Two other plant analyses will also be performed as part of the PTS work, but are not the subject of this paper. These latter two analyses are being performed by industry and will be reviewed by the USNRC for inclusion into the entire effort. The ATHEANA methodology is being applied to address the human reliability portion of the two USNRC analyses in a way that is also significantly interactive with the accident sequence and system modelling portions of the work. This paper discusses the results to date of the application of ATHEANA in these PTS analyses, including consideration of possible relevant errors of commission. The field test of ATHEANA on this project has served two purposes. One is to use it in developing technical analyses to address and solve a particular issue; i.e., the risk of PTS. The results of these analyses will be used by the USNRC to decide whether or not the PTS screening criteria should be modified. The second purpose is to test the use of ATHEANA in a real application to determine strengths and weaknesses of the method, and how it might be improved. With regard to the first purpose, the PTS project is one where a current screening criteria may be relaxed. Before that can be done, the NRC must be sure that it is safe to do so, and to the extent the specific risk values affect that decision, those values must be able to withstand public scrutiny. Since the ATHEANA process requires the analysts to identify potential vulnerabilities and challenging scenario deviations associated with a human action, and to

  18. Use and Qualification of the UMAE uncertainty methodology having as basis the CATHARE2 code

    International Nuclear Information System (INIS)

    The present paper deals with the use of the UMAE (Uncertainty Methodology Based on Accuracy Extrapolation). This methodology allows the calculation of uncertainty in the prediction by thermalhydraulic system codes of transient scenarios relevant to Nuclear Power Plants. The UMAE has been applied in an international exercise promoted by OECD/CSNI (OECD Committee on the Safety of Nuclear Installations), called UMS (Uncertainty Method Study); the qualification of uncertainty methodology constitutes one of the main purposes of UMS. The methodology has been applied in the proposed study having as the basis both the Relap5/mod2 and the Cathare2 codes calculations. In this paper, the results obtained by the use of Cathare2 code are discussed. One small break Loss of Coolant Experiment performed in the Japanese LSTF (Large Scale Test Facility) has been taken as reference test in relation to which code uncertainties have been predicted. The results of the application proved the capabilities of UMAE in predicting uncertainties at least in the considered scenario. (author)

  19. Results of a Nuclear Power Plant Application of a New Technique for Human Error Analysis (ATHEANA)

    International Nuclear Information System (INIS)

    A new method to analyze human errors has been demonstrated at a pressurized water reactor (PWR) nuclear power plant. This was the first application of the new method referred to as A Technique for Human Error Analysis (ATHEANA). The main goals of the demonstration were to test the ATHEANA process as described in the frame-of-reference manual and the implementation guideline, test a training package developed for the method, test the hypothesis that plant operators and trainers have significant insight into the error-forcing-contexts (EFCs) that can make unsafe actions (UAs) more likely, and to identify ways to improve the method and its documentation. A set of criteria to evaluate the 'success' of the ATHEANA method as used in the demonstration was identified. A human reliability analysis (HRA) team was formed that consisted of an expert in probabilistic risk assessment (PRA) with some background in HRA (not ATHEANA) and four personnel from the nuclear power plant. Personnel from the plant included two individuals from their PRA staff and two individuals from their training staff. Both individuals from training are currently licensed operators and one of them was a senior reactor operator 'on shift' until a few months before the demonstration. The demonstration was conducted over a 5-month period and was observed by members of the Nuclear Regulatory Commission's ATHEANA development team, who also served as consultants to the HRA team when necessary. Example results of the demonstration to date, including identified human failure events (HFEs), UAs, and EFCs are discussed. Also addressed is how simulator exercises are used in the ATHEANA demonstration project. (authors)

    In May of 1998, a technical basis and implementation guidelines document for A Technique for Human Event Analysis (ATHEANA) was issued as a draft report for public comment (NUREG-1624). In conjunction with the release of draft NUREG- 1624, a peer review of the new human reliability analysis method its documentation and the results of an initial test of the method was held over a two-day period in June 1998 in Seattle, Washington. Four internationally known and respected experts in HK4 or probabilistic risk assessment were selected to serve as the peer reviewers. In addition, approximately 20 other individuals with an interest in HRA and ATHEANA also attended the peer and were invited to provide comments. The peer review team was asked to comment on any aspect of the method or the report in which improvements could be made and to discuss its strengths and weaknesses. They were asked to focus on two major aspects: Are the basic premises of ATHEANA on solid ground and is the conceptual basis adequate? Is the ATHEANA implementation process adequate given the description of the intended users in the documentation? The four peer reviewers asked questions and provided oral comments during the peer review meeting and provided written comments approximately two weeks after the completion of the meeting. This paper discusses their major comments.

  7. Application of a new technique for human event analysis (ATHEANA) at a pressurized-water reactor

    International Nuclear Information System (INIS)

    Over the past several years, the US Nuclear Regulatory Commission (NRC) has sponsored the development of a new method for performing human reliability analyses (HRAs). A major impetus for the program was the recognized need for a method that would not only address errors of omission (EOOs), but also errors of commission (EOCs). Although several documents have been issued describing the basis and development of the new method referred to as ''A Technique for Human Event Analysis'' (ATHEANA), two documents were drafted to initially provide the necessary documentation for applying the method: the frame of reference (FOR) manual, which served as the technical basis document for the method and the implementation guideline (IG), which provided step by step guidance for applying the method. Upon the completion of the draft FOR manual and the draft IG in April 1997, along with several step-throughs of the process by the development team, the method was ready for a third-party test. The method was demonstrated at Seabrook Station in July 1997. The main goals of the demonstration were to (1) test the ATHENA process as described in the FOR manual and the IG, (2) test a training package developed for the method, (3) test the hypothesis that plant operators and trainers have significant insight into the EFCs that can make UAs more likely, and (4) identify ways to improve the method and its documentation. The results of the Seabrook demonstration are evaluated against the success criteria, and important findings and recommendations regarding ATHENA that were obtained from the demonstration are presented here

    Over the past several years, the US Nuclear Regulatory Commission (NRC) has sponsored the development of a new method for performing human reliability analyses (HRAs). A major impetus for the program was the recognized need for a method that would not only address errors of omission (EOOs), but also errors of commission (EOCs). Although several documents have been issued describing the basis and development of the new method referred to as ``A Technique for Human Event Analysis`` (ATHEANA), two documents were drafted to initially provide the necessary documentation for applying the method: the frame of reference (FOR) manual, which served as the technical basis document for the method and the implementation guideline (IG), which provided step by step guidance for applying the method. Upon the completion of the draft FOR manual and the draft IG in April 1997, along with several step-throughs of the process by the development team, the method was ready for a third-party test. The method was demonstrated at Seabrook Station in July 1997. The main goals of the demonstration were to (1) test the ATHENA process as described in the FOR manual and the IG, (2) test a training package developed for the method, (3) test the hypothesis that plant operators and trainers have significant insight into the EFCs that can make UAs more likely, and (4) identify ways to improve the method and its documentation. The results of the Seabrook demonstration are evaluated against the success criteria, and important findings and recommendations regarding ATHENA that were obtained from the demonstration are presented here.

    International Nuclear Information System (INIS)

    This paper mainly deals with the improvement in the post test accident analysis results prediction for the test no. 2, 'Total loss of feed water with failure of HPIS pumps and operator actions on primary and secondary circuit depressurization', carried-out on PSB integral test facility in May 2005. This is one the most complicated test conducted in PSB test facility. The prime objective of this test is to provide support for the verification of the accident management strategies for NPPs and also to verify the correctness of some safety systems operating only during accident. The objective of this analysis is to assess the capability to reproduce the phenomena occurring during the selected tests and to quantify the accuracy of the code calculation qualitatively and quantitatively for the best estimate code Relap5/mod3.3 by systematically applying all the procedures lead by Uncertainty Methodology based on Accuracy Extrapolation (UMAE), developed at University of Pisa. In order to achieve these objectives test facility nodalisation qualification for both 'steady state level' and 'on transient level' are demonstrated. For the 'steady state level' qualification compliance to acceptance criteria established in UMAE has been checked for geometrical details and thermal hydraulic parameters. The following steps have been performed for evaluation of qualitative qualification of 'on transient level': visual comparisons between experimental and calculated relevant parameters time trends; list of comparison between experimental and code calculation resulting time sequence of significant events; identification/verification of CSNI phenomena validation matrix; use of the Phenomenological Windows (PhW), identification of Key Phenomena and Relevant Thermal-hydraulic Aspects (RTA). A successful application of the qualitative process constitutes a prerequisite to the application of the quantitative analysis.

    Radiotherapy of brain lesions near critical structures requires a high accuracy in the location and dose. The high precision is achieved by the location of the stereotactic apparatus. The accuracy in dose delivery should be accompanied by an accurate quality control in devices that involve the practice, however, still does not guarantee the dose at the time of therapy. The large number of fields and the small size of these conventional methods difficult dosimetry during treatment. The objective of this work was to develop a verification methodology in vivo dosimetry in stereotactic radiotherapy with the aid of the film radiochromic Linear Accelerator with multi leaf collimators Moduleaf. The technique uses film segments radiochromic Gafchromic EBT2, with dimensions of 1x1 cm{sup 2} in area outside the coupled micro-multileaf Moduleaf Siemens. These films were inserted in the region of the central axis of the beam. The films were irradiated and calibrated to obtain the factors that determine the size dependence of the dosimetric field. With these data, we designed a computer program which calculates the density of a film must acquire when subjected to an exposure in this setting. This study evaluated five non-coplanar plans, the first with 15 fields and the other with 25 fields. Before starting the procedure, the film segment is coupled to the device, and after the treatment, the relative density is evaluated and compared with the calculated. The average value of the verification at the time of radiation dosimetry compared with the calculated by the sheet was 1.5%. The data collected in this study showed a satisfactory agreement between measured and calculated by the program in the densitometer. Thus, a methodology was developed to verify in vivo dosimetry in radiotherapy and stereotactic linear accelerator collimators Moduleaf. (author)

    The final steps of generating electricity from concentrated solar power technologies are similar to conventional thermal processes, since steam or gas is also employed for moving turbines or pistons. The fundamental difference lies on the fact that steam or hot gas is generated by solar radiation instead of fossil fuels or nuclear heat. The cheapest electricity generated from solar energy has been achieved with large-scale power stations based on this concept. Computer simulations represent a low-cost option for the design of thermal systems. The present study aims to develop a methodology for the transient simulation of a micro-scale solar-thermal power plant (120 kWe) which should be appropriate in terms of accuracy and computational effort. The facility considered can optionally operate as a cogeneration plant producing electric power as well as chilled water. Solar radiation is collected by parabolic troughs, electricity is generated by an organic Rankine cycle and chilled water is produced by an absorption cooling cycle. The organic Rankine cycle is of interest because it allows for a plant with relatively simple structure and automated operation. The simulation methodology proposed in this study is implemented in TRNSYS with new components (TYPEs) developed for the solar field and thermal cycles. The parabolic trough field component is based on an experimental efficiency curve of the solar collector. In the case of the Rankine and absorption cycles, the components are based on performance polynomials generated with EES from detailed thermodynamic models, which are calibrated with performance data from manufacturers. Distinct plant configurations are considered. An optimization algorithm is used for searching the best operating point in each case. Results are presented for the following Brazilian sites: Fortaleza, Petrolina and Bom Jesus da Lapa. The latter offers the highest global plant performance.

    The RAM (Reliability, Availability and Maintainability) main objective is assess the system and equipment performance in order to identify the critical issues to implement system's improvements. The first step is define equipment failure modes and it's PDF as well as repair time for each failure mode. The second step is modeling system regarding diagram block logic dependency among equipment and its failures which cause system production losses. The third step is simulating model in defined period of time in order to identify critical equipment to propose system improvement. Despite being having been used constantly to assess system performances, those methodology do not consider the logistic complex assumptions in so many cases to huge systems and it RDB logic do not represent the real effect in production losses. Even if that good enough to perform system analysis it's not quite enough to complex system with logistic resources regarding system's products efficiency. By the other way round, in logistic complex system analysis methodologies, equipment failures details are not regarded in so many times, showing that there's a necessary improvement in those analysis. Therefore, the RAM + L analysis is a methodology which regards all equipment failures issues as well as logistic assumptions being a more realistic analysis.

    The hydro-generators suffer during its operative useful life a combination of stresses of nature thermal, electric, mechanics and environmental. With the time, they are going losing the capacity to support those stresses and the power plants suffer, more and more frequently, undesirable stops for repair services and maintenance. In function of the high costs incurred with these stopped, the operation of the power plant can be economically impracticable. That unavailability of the generation for the electric system, it results in reduction of the reliability, burdening the politics of load ruling. The re-potentiation is a proposal that seeks to extend the useful life of hydro-generators, at the same time that it try to rescue the reliability and the readiness of the plant, with larger power. The power increase is usually made possible, or for the surplus of the hydro resources in excess, or for the reduction of the losses of all the components of the energy flow. That work proposes a methodology structured starting from the estimate of the potential, of rising of data, of the basic project and of the executive project. Modern techniques of engineering, new processes and new materials, allow the re-potentiation of those hydro-generators returning them new useful life, under conditions economically justifiable.

    The quantity kerma area product (PKA) is important to establish reference levels in diagnostic radiology exams. This quantity can be obtained using a PKA meter. The use of such meters is essential to evaluate the radiation dose in radiological procedures and is a good indicator to make sure that the dose limit to the patient's skin doesn't exceed. Sometimes, these meters come fixed to X radiation equipment, which makes its calibration difficult. In this work, it was developed a methodology for calibration of PKA meters. The instrument used for this purpose was the Patient Dose Calibrator (PDC). It was developed to be used as a reference to check the calibration of PKA and air kerma meters that are used for dosimetry in patients and to verify the consistency and behavior of systems of automatic exposure control. Because it is a new equipment, which, in Brazil, is not yet used as reference equipment for calibration, it was also performed the quality control of this equipment with characterization tests, the calibration and an evaluation of the energy dependence. After the tests, it was proved that the PDC can be used as a reference instrument and that the calibration must be performed in situ, so that the characteristics of each X-ray equipment, where the PKA meters are used, are considered. The calibration was then performed with portable PKA meters and in an interventional radiology equipment that has a PKA meter fixed. The results were good and it was proved the need for calibration of these meters and the importance of in situ calibration with a reference meter. (author)

    Full Text Available Hoje em dia as indústrias têm de colocar seus produtos em um mercado altamente competitivo, e as pressões, visando eficiência do programa de testes e do ciclo de desenvolvimento de um produto, são cada vez maiores. Neste contexto, os métodos estatísticos clássicos (baseados na teoria de amostragem, usados para analisar a confiabilidade de um produto, mostram-se cada vez menos eficientes, enquanto que os métodos bayesianos são vistos favoravelmente e seu uso começa a ser uma alternativa necessária. Para avaliar o desempenho de um item, que possui uma taxa de falhas muito baixa, as técnicas estatísticas clássicas exigem tamanhos grandes de amostra e tempo de teste longo, principalmente quando a tecnologia do produto limita o fator de aceleração, como é o caso dos produtos eletrônicos, por exemplo. A metodologia, proposta neste artigo, combina resultados de testes, que são realizados rotineiramente durante o ciclo de desenvolvimento, com informação adicional relevante e útil ao estabelecimento da confiabilidade do equipamento. Com o objetivo de ilustrar a metodologia, esta é aplicada em um equipamento eletrônico, cuja confiabilidade foi estabelecida, durante sua fase de projeto, a partir das confiabilidades de seus componentes, utilizando dados de teste por atributo e incorporando o julgamento da equipe de desenvolvimento do produto.Nowadays industries have to place their products in a highly competitive market, and there have been increasing pressures on efficiency test programs and product development cycles. In this context, the classical statistical methods (based on sampling theory, which are used to analyze product reliability, are negatively affected, while the bayesian methods are favorably regarded, and their use is becoming a necessary alternative. In order to evaluate the performance of an item with a very low failure rate, the classical statistical techniques require a large sample size and a long test time

A classificação em ecounidades é uma metodologia rápida e barata, mas com baixa reprodutibilidade. O densiômetro produz medidas rápidas e confiáveis, e o luxímetro e a fotografia com lente de 32 mm forneceram dados com pouca precisão, pois são sensíveis a pequenas variações do dossel, e a fotografia com lente de 8 mm é uma metodologia rápida e de alta precisão, mas apresenta alto custo. Analisando-se a estrutura do dossel, não houve diferenças significativas entre o densiômetro e a fotografia em 8 mm em nenhum dos dois ambientes; a fotografia em 32 mm apresentou resultados diferentes, com grande variação nas médias, indicando alta sensibilidade a pequenas alterações no dossel. Na avaliação da quantidade de luz que penetra no sub-bosque, o luxímetro e a lente de 8 mm foram diferentes. Todas as metodologias apresentaram diferenças entre a floresta madura e o reflorestamento.The objectives of this work were: (1 to investigate the efficiency, advantages and disadvantages of five methodologies to evaluate canopy structure (eco-unit interpretation, spherical densiometer, hemispheric photography with 8 mm lens and digital photography with 32 mm lens and the amount of light crossing it (using light meter and hemispheric photography with 8 mm lens and (2 to compare the canopy structure of a reforestation area and a semideciduous forest fragment in northern Paraná.

    Full Text Available A utilização de técnicas avançadas de controlo não destrutivo como o Time of Flight Detection (ToFD e o Phased Array para inspeção em manutenção de reservatórios de pressão permite a caracterização de numerosos defeitos não detectados durante a construção, como defeitos planares, cuja detecção por radiografia depende da sua orientação. Estas técnicas têm conduzido a um aumento substancial da fiabilidade dos equipamentos, uma vez que a detecção de defeitos num estágio inicial de desenvolvimento permite planear as intervenções, reduzir paragens e tempos não produtivos. Os defeitos de fabrico são identificados nas inspeções de manutenção pelo fato das técnicas usadas serem mais precisas e as áreas inspecionadas maiores do que as requeridas após construção. Alguns defeitos são facilmente classificados como tendo origem no fabrico e construção, mas outros não conseguem distinguir-se dos provocados pelas condições de serviço. Neste sentido, a decisão importante a tomar é a de avaliar se a evolução do defeito é possível de ocorrer, baseada no conhecimento das condições de serviço, do material, da dimensão e localização do defeito. Este artigo pretende fazer uma proposta de metodologia de avaliação de defeitos baseada num conjunto substancial de casos industriais de modo a apoiar o pessoal técnico nas fases de decisão em manutenção, inspeção e reparação de defeitos em juntas soldadas em reservatórios de pressão de processo.The use of advanced non-destructive techniques like ToFD and Phased Array to perform maintenance inspections of pressure vessels enables the characterization of numerous defects not detectable during the construction, as planar defects, whose detection by radiography is highly dependent on its orientation.

    Full Text Available Os laminadores a frio da Aperam South America são equipados com mandris que têm a função de sustentar o peso da bobina e de transmitir torque proveniente do acionamento. Os mandris são dotados de mecanismos chamados mordente, cuja função é prender a ponta da tira no início do processo de enrolamento e, assim, permitir a aplicação da tração de bobinamento. A prática atual de bobinamento considera que a aplicação da tração somente pode ser iniciada após, pelo menos, 1,5 voltas de tira no mandril, o que gera perda de rendimento físico nos laminadores. Foi desenvolvida uma metodologia para medição do atrito entre a tira e a superfície do mandril, numa aproximação das condições industriais, tendo em vista estudos posteriores para avaliação da capacidade dos mordentes dos mandris, a fim de se aplicar a tração com menos de uma volta de tira enrolada no mandril. Desenvolveu-se um modelo físico que foi construído próximo da escala real, o qual foi submetido a ensaios experimentais envolvendo segmentos dos mandris de dois laminadores. Os resultados do atrito médio na interface tira e mandril estão coerentes com os usados na literatura.The cold rolling mills of Aperam South America are equipped with mandrels which have the function of sustaining the coil load and torque transmission from the motor. The mandrels are equipped with mechanisms called grippers, whose function is to grip the tail of the strip at the beginning of the wrapping process and thus permit the winding tension application. The current winding practice considers that tension application can only be started after the wrapping up of at least 1.5 turns of the strip onto the mandrel, which generates a decline in the physical performance of the rolling mills. A methodology was developed to measure the friction between the strip and the surface of the mandrel, under approximate industrial conditions in order to further studies for evaluating madrel gripper

  1. Application of human reliability analysis methodology of second generation

    International Nuclear Information System (INIS)

    The human reliability analysis (HRA) is a very important part of probabilistic safety analysis. The main contribution of HRA in nuclear power plants is the identification and characterization of the issues that are brought together for an error occurring in the human tasks that occur under normal operation conditions and those made after abnormal event. Additionally, the analysis of various accidents in history, it was found that the human component has been a contributing factor in the cause. Because of need to understand the forms and probability of human error in the 60 decade begins with the collection of generic data that result in the development of the first generation of HRA methodologies. Subsequently develop methods to include in their models additional performance shaping factors and the interaction between them. So by the 90 mid, comes what is considered the second generation methodologies. Among these is the methodology A Technique for Human Event Analysis (ATHEANA). The application of this method in a generic human failure event, it is interesting because it includes in its modeling commission error, the additional deviations quantification to nominal scenario considered in the accident sequence of probabilistic safety analysis and, for this event the dependency actions evaluation. That is, the generic human failure event was required first independent evaluation of the two related human failure events . So the gathering of the new human error probabilities involves the nominal scenario quantification and cases of significant deviations considered by the potential impact on analyzed human failure events. Like probabilistic safety analysis, with the analysis of the sequences were extracted factors more specific with the highest contribution in the human error probabilities. (Author)

    Full Text Available Este é um artigo introdutório sobre análise de séries temporais, onde se pretende apresentar, de maneira sumária, alguns modelos estatísticos mais utilizados em análise de séries temporais . Uma série temporal, também denominada série histórica, é uma seqüência de dados obtidos em intervalos regulares de tempo durante um período específico. Na análise de uma série temporal, primeiramente deseja-se modelar o fenômeno estudado para, a partir daí, descrever o comportamento da série, fazer estimativas e, por último, avaliar quais os fatores que influenciaram o comportamento da série, buscando definir relações de causa e efeito entre duas ou mais séries. Para tanto, há um conjunto de técnicas estatísticas disponíveis que dependem do modelo definido (ou estimado para a série, bem como do tipo de série analisada e do objetivo do trabalho. Para analise de tendências, podem se ajustar modelos de regressão polinomial baseados na série inteira ou em vizinhança de um determinado ponto. Isso também pode ser realizado com funções matemáticas. Define-se como um fenômeno sazonal aquele que ocorre regularmente em períodos fixos de tempo e, se existir sazonalidade dita determinística na série, podem-se utilizar modelos de regressão que incorporem funções do tipo seno ou cosseno à variável tempo. Os modelos auto-regressivos formam outra classe de modelos. Na análise do comportamento de uma série histórica livre de tendência e de sazonalidade podem ser utilizados modelos auto-regressivos (AR ou que incorporem médias móveis (ARMA. Quando há tendência, utilizam-se os modelos auto-regressivos integrados de médias móveis (ARIMA e, para incorporar o componente de sazonalidade, utilizam-se os modelos SARIMA. Por último há os modelos lineares generalizados. Neste grupo de modelos estatísticos, a variável resposta é um processo de contagem e as variáveis independentes são variáveis candidatas a explicar o

    Full Text Available A "Produção Mais Limpa" é uma metodologia criada para aumentar a sustentabilidade ambiental das manufaturas. Devido a sua importância para o desenvolvimento sustentável, a Produção Mais Limpa foi amplamente promovida pela Organização das Nações Unidas e por diversas redes de organizações visando à difusão desta metodologia. No entanto, após mais de dez anos de atuação, estas redes para a difusão da Produção Mais Limpa têm se confrontado com significativas e recorrentes barreiras organizacionais que limitam seu desempenho. Utilizando-se do referencial teórico de "organizações em rede" no contexto da inovação, este artigo se baseia num aprofundado estudo de caso sobre uma estrutura organizacional em rede dentro de uma empresa multinacional que opera dezenas de manufaturas em diversos países. Esta empresa triplicou o desempenho ambiental em toneladas de poluição prevenidas e multiplicou em oito vezes o número de projetos de Produção Mais Limpa bem sucedidos, após ter implementado uma estrutura organizacional em rede para aumentar sua capacidade de gerenciar projetos para a melhoria de processos. Para explicar os motivos de tal aumento de desempenho ambiental, o artigo utiliza a metodologia de modelagem organizacional Enterprise Knowledge Development (EKD para descrever as interações entre os objetivos, regras e processos do Programa de Produção Mais Limpa desta corporação, assim como as suas estruturas de relacionamento entre os atores que viabilizaram a integração das competências necessárias para a geração de uma maior capacidade de inovação ambientalmente sustentável nas manufaturas.Cleaner Production is a methodology to improve environmental sustainability in manufacturers.

    The objective of this study was to develop a methodology for estimating the radiological impact on man of the residues of naturally occurring radioactive materials (NORMs) that potentially can be used for the construction of homes and roads. Residues of this type, which are being produced in great quantities by the Brazilian mining industry, are typically deposited in non-appropriated conditions such that they may have a long-time adverse impact on the environment, and hence on man. A mathematical model was developed to calculate the doses resulting from the use of NORM residues, thus allowing a preliminary analysis of the possibility to recycle the residues. The model was used to evaluate the external dose due gamma radiation, the dose to skin caused by beta radiation, and the internal dose due to inhalation of radon and its decay products. The model was verified by comparisons with results of other studies about doses due to gamma and beta radiation from finite and infinite radioactive sources, with relatively good agreement. In order to validate the proposed methodology, a comparison was made against experimental results for a house constructed in accordance with CNEN regulations using building materials containing NORM residues. Comparisons were made of the dose due to gamma radiation and the radon concentration in the internal environment. Finally, the methodology was used also to estimate the dose caused by gamma radiation from a road constructed in the state of Rondonia, Brazil, which made use of another NORM residue. (author)

    The castor bean agribusiness is supported by a complex supply chain that involves several inputs, main products and other derived products. So, the control of production costs is a basic and extremely important activity for the optimization of management processes. Using literature research, case study and assessment of scenarios, the present work was developed with the objective of conceiving a methodology, based on theoretical and economical aspects, the formation of costs and the revenue forecasting, which is applied with the aid of a computational program for supporting decision taking in the castor bean small producers agribusiness. The results obtained in the case study show, for example, that about 40% of the projects are considered accepted under the criterion of recovering the invested capital in less than 2 years. Also, it reveals that 75% of the projects contribute for the increase of the producer income and about 63% of the projects provide enough profit to add value to the producer's properties. Finally, it is clear that the proposed methodology makes easier a better agricultural planning, allowing a better utilization of the raw material and it facilitates the analysis of diversifying other derived products and revenue sources in the castor bean chain.

    The history of the oil industry is marked by environmental accidents, characterizing it as potentially polluter. In parallel is growing the pressure of the society, for a more responsible performance from the oil companies. In reply, the oil industry is adopting managing systems aiming to manage its environmental and social impacts. It is expected that in a first moment, the oil companies controls its social and environmental risks, for what this methodology was developed. This proposal supports the oil companies to incorporate the social and environmental variables into the economic dimension of their business, using a set of indicators. Allowing to analyze the possible influence of the business on the internal and external quality. More than analyze, making possible to prioritize a sustainable business. The application of this methodology will prevent additional costs that could be spent for those companies that did not consider the environmental and social costs of their business, and contributes also to facilitate the communication between the companies and their stakeholders.

    The main objective of this dissertation is to adapt the methodology of Strategic Environmental Assessment (SEA) to the case of ethanol fuel production in Brazil. The results are be utilized in decision-making processes as well as in the discussion on future tendencies of risks and opportunities regarding the development of ethanol as the principal renewable liquid fuel. Taking into account the international experiences of countries with a tradition in sectoral planning, SEA is found to be the instrument in public environmental management that can most adequately consider the environmental variable - beginning already at the planning stage of the ethanol industry, a necessity that has strongly unfolded itself following the deregulation of the sector in Brazil. The conflicts that may emerge from large ethanol production surpluses for export are also identified through the application of specifically designed indicators. (author)

    We present a methodology for the extraction of rules from Artificial Neural Networks (ANN) trained to forecast the electric load demand. The rules have the ability to express the knowledge regarding the behavior of load demand acquired by the ANN during the training process. The rules are presented to the user in an easy to read format, such as IF premise THEN consequence. Where premise relates to the input data submitted to the ANN (mapped as fuzzy sets), and consequence appears as a linear equation describing the output to be presented by the ANN, should the premise part holds true. Experimentation demonstrates the method's capacity for acquiring and presenting high quality rules from neural networks trained to forecast electric load demand for several amounts of time in the future.

    Nuclear medicine procedure requires the administration of radioactive material by injection, ingestion or inhalation. After incorporation, the patient becomes a mobile source of radiation and, after their examination; they can irradiate everyone on their way out of the Nuclear Medicine Service (NMS). A group of workers in this path is considered a critical group, but there are no conviction on this classification, because there are not measurements available. Thus, workers claiming for occupationally exposed individual's (OEI) rights are common. Employers are always in a complex situation, because if they decided to undertake the individual external monitoring of the critical working groups, the Court considers all as OEI and employers are taxed. On the other hand, if they do not provide monitoring, it is impossible to prove that these workers were not exposed to effective doses higher than individual annual public's limit and they lose the actions, too. This work proposes a methodology to evaluate, using TLD environmental monitors, air kerma rate at critical staff points in a NMS. This method provides relevant information about critical groups' exposure. From these results, the clinic or hospital may prove technically, without individual monitoring of employees, the classification of areas and can estimate the maximum flow of patients in the free areas which guarantees exposures below the public individual dose limit. This methodology has been applied successfully to a private clinic in Rio de Janeiro, which operates a NMS. The only critical group that received exposure statistically different from clinic background radiation was that on the antechamber of the NMS. This is a site that should be characterized as a supervised area and the group of workers in this environment as OEI, as the estimated extrapolated annual effective dose in this position was 1.2 +- 0.7 mSv/year, above the public annual limit (1,0 mSv/year). Normalizing by the number of

    This thesis presents a text mining method for semi-automatic extraction of taxonomy of concepts, from a textual corpus composed of scientific papers related to nuclear area. The text classification is a natural human practice and a crucial task for work with large repositories. The document clustering technique provides a logical and understandable framework that facilitates the organization, browsing and searching. Most clustering algorithms using the bag of words model to represent the content of a document. This model generates a high dimensionality of the data, ignores the fact that different words can have the same meaning and does not consider the relationship between them, assuming that words are independent of each other. The methodology presents a combination of a model for document representation by concepts with a hierarchical document clustering method using frequency of co-occurrence concepts and a technique for clusters labeling more representatives, with the objective of producing a taxonomy of concepts which may reflect a structure of the knowledge domain. It is hoped that this work will contribute to the conceptual mapping of scientific production of nuclear area and thus support the management of research activities in this area. (author)

    It is known that more than 20% of the world's population will contract some type of cancer. In Brazil, with the exception of skin cancer (non melanoma) the breast cancer ranks first among the higher frequency of tumours among women and in general, although the methods of detection are advancing in the year 2010 took place about 13 thousand deaths in about 50,000 cases, probably due to late detection of these neoplasm. New cases of breast cancer in a given population can be proven from absorbed dose quantity, calculated for the compressed breast, due to the risk by means of exposure to x rays in this radiodiagnostic practices. Methodology: Exposures were held in an ionization chamber and the other quantities required were obtained to the screen-film equipment of mammography. Results: Also experimental results were of compressed breast an equivalent dose of ( 1.82 mSv {+-} 0.2%) or (3.64 mSv {+-} 0.2%) for both projections, i.e. medium lateral oblique and cranio caudal. The experimental value obtained here is consistent with the calculated results and published in the literature for analog and CR equipment. Conclusion: From the result of dose equivalent in the breast, one can say that there will be effectively attesting as to the appearance of new cases of cancer if approximately 80 million women are exposed to radiation emitted by mammographers.

    The {sup 9}0Sr+{sup 9}0Y applicators, used in beta therapy for prevention of keloids and pterigio, are imported and its dosimetric features are only illustrated by the manufacturers. The exhaustive routine of the medical physicists in the clinic do not make possible the accomplishment of procedures for the confirmation of these parameters. This work presents a methodology development for dosimetry in two {sup 9}0Sr+{sup 9}0Y beta therapy applicators of the Amersham brand. The Monte Carlo code MCNP 4 C was used for the simulation of the percentage depth dose curves. The experimental measurements of the radiation attenuation had been done with a mini-extrapolation chamber. The results of the experimental measures had been compared with the simulated values. Both percentage deep dose curves, the theoretical and the experimental ones, had presented similar behavior, which may validate the use of the MCNP 4 C for these simulations, strengthening the usage of this method at procedures of dosimetry of these beta radiation sources.

A metodologia simplificada desenvolvida permitiu detectar resíduos de paraquat ao nível de 0,06 ppm, indicando uma excelente aproximação, pois, o limite de tolerância do paraquat em tubérculos de batata é de 0,2 ppm, normalmente, determinado pelo método analítico completo, que apresenta limites de detecção em torno de 0,01 ppm e recuperação acima de 70%. Uma avaliação qualitativa da concentração residual de produto nas amostras foi possível através de leitura e comparações visuais entre os diferentes graus de cores desenvolvidas nas soluções visuais entre os diferentes graus de cores desenvolvidas nas soluções padrão e a cor desenvolvida na amostra, não necessitando, portanto, das leituras colorimétricas, podendo ser feita inclusive no campo. Observou-se que a maioria do paraquat permaneceu na região de casca até o período de 4 semanas após a aplicação do paraquat.Seed potatoes tubers (Solanum tuberosum of two cultivars (Achat and Baronesa were treated with paraquat solutions to evalute the internal tuber quality and to detect its residue by a simplified methodology. Two experiments were carried out at the National Research Center on Vegetables, Brasília, DF. In experiment one some tubers were immersed in 0 and 200 ppm of paraquat solutions and others were injected with 0,5 ml of 0 and 200 ppm solutions of the herbicide. Twelve tubers were used as plot in a complete randomized design with 8 replications. The internal tuber quality was evaluated after breaking dormancy and sprouting of ten tubers. Also, two tubers were sampled and put in 5 liter pots and grown under greenhouse conditions to observe if the herbicide would affect the growth of the new plant generation. The immersion treatments did not cause any internal damage to the tubers nor did they affect the new plant generation; however, tubers injected with paraquat were severely damaged (carbonization.

However, in spite of the enormous contribution of these methodologies for the understanding of the subjects related to the human reliability, they present a variety of deficiencies that were identified along the history of practical application to the industrial projects. Considering the state-of-art in the analyses of these deficiencies, it was elaborated a set of good practices to be fulfilled by all methods of human reliability. This set of good practices is described in the recent documents of USNRC, NUREGs 1792 and 1842, of April 2005 and February 2006, respectively. In this article, the authors discuss the main technical deficiencies of the THERP methodology, when compared with the good practices criteria from USNRC.

    ER UMa stars are a recently recognized small subgroup of SU UMa-type dwarf novae, which are characterized by the extremely high outburst frequency and short (19--48 d) supercycles. From the current thermal-tidal disk instability scheme, they are considered to be high mass-transfer SU UMa-type dwarf novae, and comprise a link to "permanent superhumpers" below the period gap. They do not only provide an opportunity to test the applicability of thermal-tidal instability model but also pose problems on the origin of high mass-transfer in short orbital-period cataclysmic variables. A historical review of this subgroup and recent topics of ER UMa stars, the unique pattern of superhump evolution and the "helium ER UMa analog" (CR Boo), are also discussed.

    Full Text Available A pergunta "vulnerabilidade a que?" é primária nos estudos sobre riscos e perigos. Nos estudos populacionais, essa pergunta se direciona a grupos demográficos que estão sujeitos a determinados perigos, que podem estar relacionados às características da dinâmica demográfica ou à sua situação socioeconômica, ligadas ao ciclo vital, à estrutura familiar ou às características migratórias do grupo. O campo de população e ambiente acrescentou a dimensão espacial à problemática, considerando a posição e a situação (relacionais e relativas componentes dos elementos que produzem perigos ou que fornecem condições de enfrentá-los. Notam-se, de um lado, a influência de uma abordagem ecológica, que entende o meio como um conjunto físico-social que influencia e é influenciado pela população, e, de outro, a presença de postulados materialistas, que concebe a relação sociedade-natureza como um devir histórico-social que se pauta pela produção contraditória e desigual do espaço e da sociedade. Em ambientes fortemente modificados pelo homem, como as grandes cidades, a matriz causal de riscos e de elementos que podem interferir na vulnerabilidade é consideravelmente maior, tornando difícil apreender relações de causalidade entre determinados perigos e certas características do grupo demográfico. Em vista disso, olhar para os perigos e para a vulnerabilidade do lugar é uma estratégia que permite, em microescala, captar os elementos que interferem na produção, aceitação e mitigação dos riscos. A dimensão ecológica é re-significada ao incorporar a dimensão existencial e fenomênica do lugar, entendendo os grupos demográficos em sua relação de envolvimento e pertencimento ao seu espaço vivido. A partir de uma série de trabalhos empíricos desenvolvidos nos últimos anos, este artigo reflete sobre as possibilidades dessa perspectiva teórico-metodológica, que utiliza uma prática qualitativa de campo e

  5. Advancements in CIAU methodology

    International Nuclear Information System (INIS)

    Best-Estimate calculation results from complex thermal-hydraulic system codes (like Relap5, Cathare, Athlet, Trace, etc.) are affected by unavoidable approximations that are unpredictable without the use of computational tools that account for the various sources of uncertainty. Therefore the use of best-estimate codes within the reactor technology, either for design or safety purposes, implies understanding and accepting the limitations and the deficiencies of those codes. Uncertainties may have different origins ranging from the approximation of the models, to the approximation of the numerical solution, and to the lack of precision of the values adopted for boundary and initial conditions. The amount of uncertainty that affects a calculation may strongly depend upon the codes and the modeling techniques (i.e. the code's users). A consistent and robust uncertainty methodology must be developed taking into consideration all the above aspects. The CIAU (Code with the capability of Internal Assessment of Uncertainty) and the UMAE (Uncertainty Methodology based on Accuracy Evaluation) methods have been developed by University of Pisa in the framework of a long lasting research activities started since 80's and involving several researchers. CIAU is extensively discussed in the available technical literature, Refs. [1, 2, 3, 4, 5, 6, 7], and tens of additional relevant papers, that provide comprehensive details about the method, can be found in the bibliography lists of the above references. Therefore, the present paper supplies only 'spot-information' about CIAU and focuses mostly on the advancements of the methodology, that constitute the original contributions of the present work. In particular, the extension of the uncertainty database and the development of a procedure for the 'internal' qualification of the method are discussed.

    The human reliability analysis (HRA) is a very important part of probabilistic safety analysis. The main contribution of HRA in nuclear power plants is the identification and characterization of the issues that are brought together for an error occurring in the human tasks that occur under normal operation conditions and those made after abnormal event. Additionally, the analysis of various accidents in history, it was found that the human component has been a contributing factor in the cause. Because of need to understand the forms and probability of human error in the 60 decade begins with the collection of generic data that result in the development of the first generation of HRA methodologies. Subsequently develop methods to include in their models additional performance shaping factors and the interaction between them. So by the 90 mid, comes what is considered the second generation methodologies. Among these is the methodology A Technique for Human Event Analysis (ATHEANA). The application of this method in a generic human failure event, it is interesting because it includes in its modeling commission error, the additional deviations quantification to nominal scenario considered in the accident sequence of probabilistic safety analysis and, for this event the dependency actions evaluation. That is, the generic human failure event was required first independent evaluation of the two related human failure events . So the gathering of the new human error probabilities involves the nominal scenario quantification and cases of significant deviations considered by the potential impact on analyzed human failure events. Like probabilistic safety analysis, with the analysis of the sequences were extracted factors more specific with the highest contribution in the human error probabilities. (Author)

    Various methods have been developed independently to study the multifractality of measures in many different contexts. Although they all convey the same intuitive idea of giving a "dimension" to sets where a quantity scales similarly within a space, they are not necessarily equivalent on a more rigorous level. This review article aims at unifying the multifractal methodology by presenting the multifractal theoretical framework and principal practical methods, namely the moment method, the histogram method, multifractal detrended fluctuation analysis (MDFA) and modulus maxima wavelet transform (MMWT), with a comparative and interpretative eye.

    The MIRD (Medical Internal Radiation Dose) system was established by the Society of Nuclear Medicine of USA in 1960 to assist the medical community in the estimation of the dose in organs and tissues due to the incorporation of radioactive materials. Since then, 'MIRD Dose Estimate Report' (from the 1 to 12) and 'Pamphlets', of great utility for the dose calculations, were published. The MIRD system was planned essentially for the calculation of doses received by the patients during nuclear medicine diagnostic procedures. The MIRD methodology for the absorbed doses calculations in different tissues is explained

  9. PSA methodology

    International Nuclear Information System (INIS)

    The purpose of this text is first to ask a certain number of questions on the methods related to PSAs. Notably we will explore the positioning of the French methodological approach - as applied in the EPS 13001 and EPS 9002 PSAs - compared to other approaches (Part One). This reflection leads to more general reflection: what contents, for what PSA? This is why, in Part Two, we will try to offer a framework for definition of the criteria a PSA should satisfy to meet the clearly identified needs. Finally, Part Three will quickly summarize the questions approached in the first two parts, as an introduction to the debate. 15 refs

    Full Text Available This paper proposes a reflection on the cultural dimension as a kind of “transverse theme” in educational research. This transversality has an epistemological and methodological meaning, supported by an ethical basis. It is an approach that goes through epistemological paths which inevitably touch the inequality and exclusion theme when dealing with the field of cultural differences. Along this path “cultural plurality and education” are privileged, bringing to reflection epistemological obstacles emerged mostly from ignorance and disregard concerning cultural dimension, what may have compromised the results of educational researches in many fields. It is also emphasized the urgently necessity of including in researches and teachers formation the singular contribution brought by the comprehension of the cultural plurality phenomenon in its multiple manifestations

    Full Text Available INTRODUCTION: The growth of Internet users enables epidemiological studies to be conducted electronically, representing a promising methodology for data collection. METHODS: Members of Ethics Committees, Clinical Researchers and Sponsors were interviewed using questionnaires sent over the Internet. Along with the questionnaire, participants received a message explaining the survey and also the informed consent. Returning the questionnaire meant the consent of the participant was given. No incentive was offered; two reminders were sent. RESULTS: The response rate was 21% (124/599, 20% (58/290 and 45% (24/53 respectively for Ethics Committees, Researchers and Sponsors. The percentage of return before the two reminders was about 62%. Reasons for non-response: participant not found, refusal to participate, lack of experience in clinical research or in the therapeutic field. Characteristics of participants: 45% of Ethics Committee participants, 64% of Researchers and 63% of Sponsors were male; mean age (range, respectively: 47 (28-74, 53 (24-72 and 40 (29-65 years. Among Researchers and Sponsors, all respondents had at least a university degree and, in the Ethics Committees group, only two (1.7% did not have one. Most of the questionnaires in all groups came from the Southeast Region of Brazil, probably reflecting the highest number of clinical trials and research professionals in this region. CONCLUSION: Despite the potential limitations of a survey done through the Internet, this study led to a response rate similar to what has been observed with other models, efficiency in obtaining responses (speed and quality, convenience for respondents and low cost.INTRODUÇÃO: O crescimento de usuários da Internet possibilita que estudos epidemiológicos sejam conduzidos eletronicamente, representando uma promissora metodologia para coleta de dados.

  12. A technique for human error analysis (ATHEANA)

    International Nuclear Information System (INIS)

    Probabilistic risk assessment (PRA) has become an important tool in the nuclear power industry, both for the Nuclear Regulatory Commission (NRC) and the operating utilities. Human reliability analysis (HRA) is a critical element of PRA; however, limitations in the analysis of human actions in PRAs have long been recognized as a constraint when using PRA. A multidisciplinary HRA framework has been developed with the objective of providing a structured approach for analyzing operating experience and understanding nuclear plant safety, human error, and the underlying factors that affect them. The concepts of the framework have matured into a rudimentary working HRA method. A trial application of the method has demonstrated that it is possible to identify potentially significant human failure events from actual operating experience which are not generally included in current PRAs, as well as to identify associated performance shaping factors and plant conditions that have an observable impact on the frequency of core damage. A general process was developed, albeit in preliminary form, that addresses the iterative steps of defining human failure events and estimating their probabilities using search schemes. Additionally, a knowledge- base was developed which describes the links between performance shaping factors and resulting unsafe actions

    2004-06-01

    Full Text Available The study of population dynamics has long depended on methodological progress. Among many striking examples, continuous time models for populations structured in age (Sharpe & Lotka, 1911 were made possible by progress in the mathematics of integral equations. Therefore the relationship between population ecology and mathematical and statistical modelling in the broad sense raises a challenge in interdisciplinary research. After the impetus given in particular by Seber (1982, the regular biennial EURING conferences became a major vehicle to achieve this goal. It is thus not surprising that EURING 2003 included a session entitled “Methodological advances”. Even if at risk of heterogeneity in the topics covered and of overlap with other sessions, such a session was a logical way of ensuring that recent and exciting new developments were made available for discussion, further development by biometricians and use by population biologists. The topics covered included several to which full sessions were devoted at EURING 2000 (Anderson, 2001 such as: individual covariates, Bayesian methods, and multi–state models. Some other topics (heterogeneity models, exploited populations and integrated modelling had been addressed by contributed talks or posters. Their presence among “methodological advances”, as well as in other sessions of EURING 2003, was intended as a response to their rapid development and potential relevance to biological questions. We briefly review all talks here, including those not published in the proceedings. In the plenary talk, Pradel et al. (in prep. developed GOF tests for multi–state models. Until recently, the only goodness–of–fit procedures for multistate models were ad hoc, and non optimal, involving use of standard tests for single state models (Lebreton & Pradel, 2002. Pradel et al. (2003 proposed a general approach based in particular on mixtures of multinomial distributions. Pradel et al. (in prep. showed

Porém pretende apresentar apenas uma entre as várias argumentações possíveis em favor desta concepção: defende que a amizade, no sentido exposto, seja a solução mais convincente ao problema da intersubjetividade. A questão é como a  concepção da subjetividade pode ser entendida a outros indivíduos, se essa, como o autor defende pode ser compreendida priginariamente somente a partir da auto-referência da primeira pessoa. Para isso, ele faz uso do conceito aristotélico do amor amigável enquanto direcionado a um "heterosautos", identificando como seus momentos tanto o conhecimento e o desejo do outro, como o respeito e a benevolência. Os últimos dois momentos são interpretados como "conversão" da consciência dos primeiros. Por meio dessa "conversão da consciência" a consciência do Outro é estabelecida. Como se trata da conversão de uma consciência concreta, tanto cognitiva quanto volitiva, seu resultado não é um conceito abstrato e geral de uma subjetividade diferente da minha, mas uma relação concreta entre indivíduos que implica um compromisso e a partir da qual forma-se um étos específico da comunidade assim estabelecida.

    Full Text Available Uma das principais características da metodologia científica está na descrição detalhada de todas as condições experimentais e especialmente dos critérios adotados para se constituir uma amostra e obterem-se os dados. Esta característica deve ser aplicada em todos os trabalhos para permitir a outros estudiosos repetir o mesmo trabalho sob as mesmas condições descritas, e assim obter-se os mesmos resultados em qualquer parte do mundo. Esta possibilidade, além de permitir a checagem dos dados relatados, confere uma maior credibilidade perante a comunidade científica. Em ciência os dados devem ser públicos e reprodutíveis. Ao estudar-se as reabsorções dentárias, a padronização da amostra, dos critérios de diagnóstico e de classificação é muito importante. A reabsorção dentária representa um fenômeno multifatorial, ou seja, pode ser induzida por muitas causas e influenciadas por inúmeros fatores como morfologia dentária e óssea, proporção coroa-raiz, tipo de má oclusão, técnica empregada, extensão do movimento e outros. Para um trabalho sobre este tema apresentar maior credibilidade em seus resultados requer-se uma amostra muito homogênea, uma padronização do diagnóstico e da técnica ortodôntica com alto nível de calibração. Infelizmente muitos trabalhos sobre reabsorções dentárias, especialmente as que ocorrem durante o tratamento ortodôntico, são estudadas em amostras acumuladas no tempo, sem padronização diagnóstica e técnica, com pacientes tratados por inúmeros operadores, sem considerar a necessidade de padronização da amostra em algumas variáveis importantes nem tampouco relevá-las ou discuti-las quando das análises dos resultados. O objetivo deste trabalho constitui induzir reflexões sobre este assunto e sugerir alguns parâmetros para a análise de trabalhos de pesquisas pertinentes às reabsorções dentárias e à biologia da movimentação ortodôntica.One of the main

    2003-01-01

    Full Text Available The aim of this paper is to describe a methodology for research with families in natural environment: Ecological Insertion. This methodology is based on Ecological Systems Theory, that proposes that development must be studied through a scientific model that involves interaction among four nucleus: process, person, context and time, denominated bioecological model. For this theory, the bioecological model become an appropriate theoretical-methodologial approach for research on development-in-context. This paper describes an operacionalization of this model in a qualitative research about resilience and vulnerability in families under risk situation. The ecological insertion involved the study accompaniment of three poor families who live in a violent community and included observations, informal chats and interviews. The operacionalization of the bioecological model in this research promoted the accomplishment of a study with ecological validity, apart from allowing to include various levels of analysis.

Direct WBC counts using the Natt and Herrick method showed limitations, which are discussed here. The WBC and TT counts using 1,000 erythrocytes from blood smears are not recommended for Amazon turtles nor other reptilian species, since wide variation in counts can be observed. Estimation methods for determining WBC and TT based on 2,000 erythrocytes of blood smears were most acceptable because they allow a differentiation between leukocytes and thrombocytes and also had a smaller variation.

  13. CIAU methodology and BEPU applications

    International Nuclear Information System (INIS)

    Best-Estimate calculation results from complex thermal-hydraulic system codes (like Relap5, Cathare, Athlet, Trace, etc..) are affected by unavoidable approximations that are unpredictable without the use of computational tools that account for the various sources of uncertainty. Therefore the use of best-estimate codes within the reactor technology, either for design or safety purposes, implies understanding and accepting the limitations and the deficiencies of those codes. Uncertainties may have different origins ranging from the approximation of the models, to the approximation of the numerical solution, and to the lack of precision of the values adopted for boundary and initial conditions. The amount of uncertainty that affects a calculation may strongly depend upon the codes and the modeling techniques (i.e. the code's users). A consistent and robust uncertainty methodology must be developed taking into consideration all the above aspects. The CIAU (Code with the capability of Internal Assessment of Uncertainty) and the UMAE (Uncertainty Methodology based on Accuracy Evaluation) methods have been developed by University of Pisa (UNIPI) in the framework of a long lasting research activities started since 80's and involving several researchers. CIAU is extensively discussed in the available technical literature, Refs. [1, 2, 3, 4, 5, 6, 7], and tens of additional relevant papers, that provide comprehensive details about the method, can be found in the bibliography lists of the above references. Therefore, the present paper supplies only 'spot-information' about CIAU and focuses mostly on the applications to some cases of industrial interest. In particular the application of CIAU to the OECD BEMUSE (Best Estimate Methods Uncertainty and Sensitivity Evaluation, [8, 9]) project is discussed and a critical comparison respect with other uncertainty methods (in relation to items like: sources of uncertainties, selection of the input parameters and quantification of

    1950-01-01

    Full Text Available Nos extensos trabalhos de melhoramento do cafeeiro, há 18 anos em realização na Subdivisão de Genética do Instituto Agronômico, tem-se dedicado especial atenção à espécie C. arabica L., pelo fato de todos os nossos cafèzais pertencerem a esta espécie que, sem dúvida, fornece o produto de melhor qualidade. Nas regiões de terras extremamente cansadas, um dos principais fatôres levados em consideração no melhoramento é a rusticidade, caráter êsse, entretanto, encontrado de preferência em outras espécies, tais como o C. canephora e C. Dewevrei, cujos cafés são de má qualidade. A hibridação interespecífica, que poderia reunir em uma só planta caraterísticos de rusticidade e boa qualidade de bebida, tem o inconveniente de dar origem a plantas triplóides, que são estéreis. Daí se deduz que a obtenção artificial de formas que combinassem êsses caraterísticos constitui problema, cuja solução é extremamente demorada. No presente trabalho, apresentam-se os caracteres de uma nova forma de Coffea, encontrada em cafèzal da Fazenda Itaporã, em Terra Roxa, município de Viradouro, que, com algumas ressalvas, oferece a desejada combinação de caracteres. Trata-se, provàvelmente, de um híbrido espontâneo entre C. arabica e C. Dewevrei, com 2n = 44 cromosômios, extremamente rústico e produtivo, cujas sementes fornecem uma bebida que pode ser classificada como boa. Apenas apresenta, como principal defeito, uma auto-esterilidade quase completa. Os seus caraterísticos botânicos são descritos em detalhe.

  16. Uma cidade pós‑criativa?

    Directory of Open Access Journals (Sweden)

    Malcom Miles

    2013-09-01

    Full Text Available Na década de 1990, a reabilitação urbana de base cultural tornou‑se regra na Europa, legitimada pelo conceito de cidade criativa. Em alguns casos, esse processo levou a uma marginalização de culturas locais; noutros, a esperada nova prosperidade não se concretizou com a estetização do espaço e o resultante do enobrecimento urbano (gentrification. A cidade criativa é uma cidade socialmente fragmentada na qual se valoriza a cultura entendida como as artes, em detrimento da cultura enquanto articulação de valores partilhados no quotidiano. Contudo, a crise financeira de 2008 intercetou esta trajetória, proporcionando uma oportunidade para reavaliar o conceito de cidade criativa e os seus valores implícitos. Têm aparecido alternativas, nomeadamente o movimento Ocupa e a arte ativista. Poderá existir uma cidade pós‑criativa? Poderá a imaginação criativa de uma diversidade de grupos urbanos levar a novas formações sociopolíticas e culturais? Isso constituiria possivelmente uma outra revolução urbana.

    Kammerer, Catherine C.

    2009-01-01

    Journal article about Reliability Centered Maintenance (RCM) methodologies used by United Space Alliance, LLC (USA) in support of the Space Shuttle Program at Kennedy Space Center. The USA Reliability Centered Maintenance program differs from traditional RCM programs because various methodologies are utilized to take advantage of their respective strengths for each application. Based on operational experience, USA has customized the traditional RCM methodology into a streamlined lean logic path and has implemented the use of statistical tools to drive the process. USA RCM has integrated many of the L6S tools into both RCM methodologies. The tools utilized in the Measure, Analyze, and Improve phases of a Lean Six Sigma project lend themselves to application in the RCM process. All USA RCM methodologies meet the requirements defined in SAE JA 1011, Evaluation Criteria for Reliability-Centered Maintenance (RCM) Processes. The proposed article explores these methodologies.

    International Nuclear Information System (INIS)

    In the period 1981-1994, SKB has studied several methodologies to systematize and visualize all the features, events and processes (FEPs) that can influence a repository for radioactive waste in the future. All the work performed is based on the terminology and basic findings in the joint SKI/SKB work on scenario development presented in the SKB Technical Report 89-35. The methodologies studied are a) Event tree analysis, b) Influence diagrams and c) Rock Engineering Systems (RES) matrices. Each one of the methodologies is explained in this report as well as examples of applications. One chapter is devoted to a comparison between the two most promising methodologies, namely: Influence diagrams and the RES methodology. In conclusion a combination of parts of the Influence diagram and the RES methodology is likely to be a promising approach. 26 refs

    The fallout from a nuclear explosion has the potential to injure or kill 100,000 or more people through exposure to external gamma (fallout) radiation. Existing buildings can reduce radiation exposure by placing material between fallout particles and exposed people. Lawrence Livermore National Laboratory was tasked with developing an operationally feasible methodology that could improve fallout casualty estimates. The methodology, called a Regional Shelter Analysis, combines the fallout protection that existing buildings provide civilian populations with the distribution of people in various locations. The Regional Shelter Analysis method allows the consideration of (a) multiple building types and locations within buildings, (b) country specific estimates, (c) population posture (e.g., unwarned vs. minimally warned), and (d) the time of day (e.g., night vs. day). The protection estimates can be combined with fallout predictions (or measurements) to (a) provide a more accurate assessment of exposure and injury and (b) evaluate the effectiveness of various casualty mitigation strategies. This report describes the Regional Shelter Analysis methodology, highlights key operational aspects (including demonstrating that the methodology is compatible with current tools), illustrates how to implement the methodology, and provides suggestions for future work.

    Full Text Available As últimas décadas têm favorecido o crescimento do interesse e dos estudos sobre a ética jornalística. No Brasil e em outras praças, as abordagens deste tema têm sido na maioria das vezes por um caráter deontológico ou utilitarista. Neste artigo, chamamos a atenção para uma perspectiva que privilegie as virtudes como pontos de partida para os debates acerca das condutas dos profissionais. Uma ética das virtudes remete a Aristóteles e aos estoicos, mas vem sendo retomada por autores mais contemporâneos, como Macintyre e Comte-Sponville, entre outros. No jornalismo, esta abordagem não é definitiva ou totalizante, mas contribui para uma compreensão mais ampla da discussão, chamando inclusive a atenção para recomendações éticas úteis, práticas e atuais.

    1982-01-01

    It is important for industry and NASA to assess the status of acoustic design technology for predicting and controlling helicopter external noise in order for a meaningful research program to be formulated which will address this problem. The prediction methodologies available to the designer and the acoustic engineer are three-fold. First is what has been described as a first principle analysis. This analysis approach attempts to remove any empiricism from the analysis process and deals with a theoretical mechanism approach to predicting the noise. The second approach attempts to combine first principle methodology (when available) with empirical data to formulate source predictors which can be combined to predict vehicle levels. The third is an empirical analysis, which attempts to generalize measured trends into a vehicle noise prediction method. This paper will briefly address each.

  15. Soft Systems Methodology

    Science.gov (United States)

    Checkland, Peter; Poulter, John

    Soft systems methodology (SSM) is an approach for tackling problematical, messy situations of all kinds. It is an action-oriented process of inquiry into problematic situations in which users learn their way from finding out about the situation, to taking action to improve it. The learning emerges via an organised process in which the situation is explored using a set of models of purposeful action (each built to encapsulate a single worldview) as intellectual devices, or tools, to inform and structure discussion about a situation and how it might be improved. This paper, written by the original developer Peter Checkland and practitioner John Poulter, gives a clear and concise account of the approach that covers SSM's specific techniques, the learning cycle process of the methodology and the craft skills which practitioners develop. This concise but theoretically robust account nevertheless includes the fundamental concepts, techniques, core tenets described through a wide range of settings.

  19. Soil Radiological Characterisation Methodology

    International Nuclear Information System (INIS)

    This report presents the general methodology and best practice approaches which combine proven existing techniques for sampling and characterisation to assess the contamination of soils prior to remediation. It is based on feedback of projects conducted by main French nuclear stakeholders involved in the field of remediation and dismantling (EDF, CEA, AREVA and IRSN). The application of this methodology will enable the project managers to obtain the elements necessary for the drawing up of files associated with remediation operations, as required by the regulatory authorities. It is applicable to each of the steps necessary for the piloting of remediation work-sites, depending on the objectives targeted (release into the public domain, re-use, etc.). The main part describes the applied statistical methodology with the exploratory analysis and variogram data, identification of singular points and their location. The results obtained permit assessment of a mapping to identify the contaminated surface and subsurface areas. It stakes the way for radiological site characterisation since the initial investigations from historical and functional analysis to check that the remediation objectives have been met. It follows an example application from the feedback of the remediation of a contaminated site on the Fontenay aux Roses facility. It is supplemented by a glossary of main terms used in the field from different publications or international standards. This technical report is a support of the ISO Standard ISO ISO/TC 85/SC 5 N 18557 'Sampling and characterisation principles for soils, buildings and infrastructures contaminated by radionuclides for remediation purposes'.

    International Nuclear Information System (INIS)

    A few general features of microscopics evolution and their relationship with microscopics methodology are briefly surveyed. Several pluri-disciplinary and interdisciplinary aspects of microscopics research are also discussed in the present scientific context. The need for an equilibrium between individual tendencies and collective constraints required by team work, already formulated thirty years ago by Frederic Joliot, is particularly stressed in the present conjuncture of Nuclear Research favouring very large team projects and discouraging individual initiatives. The increasing importance of the science of science (due to their multiple social, economical, ecological aspects) and the stronger competition between national and international tendencies of scientific (and technical) cooperation are also discussed.

The determination of the sample size is considered for ranking and selection problems as well as for the design of clinical trials. Appropria

  9. Electronic system hardening methodology

    International Nuclear Information System (INIS)

    The notion of hardened systems can be found in several applications (nuclear power plants, alarm systems, research installations..). Their development correspond to the functional necessity to take into account a specific radiative environment. The starting point of each hardening study is the definition of the radiative environmental constraints representative of the application. In addition to these external constraints, the specific functional characteristics of each system are considered: control or interface systems in nuclear industry, in-board control systems, remote handling systems, etc. This paper summarizes the methodology followed according to the experience gained in previous studies and anticipating the future needs.

  12. Relative Hazard Calculation Methodology

    International Nuclear Information System (INIS)

    The methodology presented in this document was developed to provide a means of calculating the RH ratios to use in developing useful graphic illustrations. The RH equation, as presented in this methodology, is primarily a collection of key factors relevant to understanding the hazards and risks associated with projected risk management activities. The RH equation has the potential for much broader application than generating risk profiles. For example, it can be used to compare one risk management activity with another, instead of just comparing it to a fixed baseline as was done for the risk profiles. If the appropriate source term data are available, it could be used in its non-ratio form to estimate absolute values of the associated hazards. These estimated values of hazard could then be examined to help understand which risk management activities are addressing the higher hazard conditions at a site. Graphics could be generated from these absolute hazard values to compare high-hazard conditions. If the RH equation is used in this manner, care must be taken to specifically define and qualify the estimated absolute hazard values (e.g., identify which factors were considered and which ones tended to drive the hazard estimation)

  13. RHIC Data Correlation Methodology

    International Nuclear Information System (INIS)

    A requirement for RHIC data plotting software and physics analysis is the correlation of data from all accelerator data gathering systems. Data correlation provides the capability for a user to request a plot of multiple data channels vs. time, and to make meaningful time-correlated data comparisons. The task of data correlation for RHIC requires careful consideration because data acquisition triggers are generated from various asynchronous sources including events from the RHIC Event Link, events from the two Beam Sync Links, and other unrelated clocks. In order to correlate data from asynchronous acquisition systems a common time reference is required. The RHIC data correlation methodology will allow all RHIC data to be converted to a common wall clock time, while still preserving native acquisition trigger information. A data correlation task force team, composed of the authors of this paper, has been formed to develop data correlation design details and provide guidelines for software developers. The overall data correlation methodology will be presented in this paper

  18. Technical specification compliance methodology

    International Nuclear Information System (INIS)

    The fundamental purpose of the plant technical specifications (tech specs) is to impose requirements on plant operations such that the evaluated safety analysis basis of the plant is maintained. As plants have become more complex and with an increased emphasis on plant and personnel safety, management of the tech specs requires significant time and resources on the part of nuclear utility organizations. Westinghouse Electric Corporation in conjunction with Union Electric Company has developed a computer-based methodology to help the plant operations staff maintain compliance with the tech specs. This system, called SPECAPPRAISAL which was recently implemented at the Callaway Plant site involves a combination of Fault Tree Analysis techniques, database management, Man-Machine Interface design, and computer software

Yet, Einstein wrote to Arnold Sommerfeld that Grossman will never claim to be considered a co-discoverer of the Einstein-Grossmann theory. He only helped in guiding Einstein through the mathematical literature, but contributed nothing of substance to the results of the theory. Hence, Einstein neither considered Besso or Grossmann as co-discoverers of the relativity theory which he invented.

  5. Engineering radioecology: Methodological considerations

    International Nuclear Information System (INIS)

    The term ''radioecology'' has been widely recognized in scientific and technical societies. At the same time, this scientific school (radioecology) does not have a precise/generally acknowledged structure, unified methodical basis, fixed subjects of investigation, etc. In other words, radioecology is a vast, important but rather amorphous conglomerate of various ideas, amalgamated mostly by their involvement in biospheric effects of ionizing radiation and some conceptual stereotypes. This paradox was acceptable up to a certain time. However, with the termination of the Cold War and because of remarkable political changes in the world, it has become possible to convert the problem of environmental restoration from the scientific sphere in particularly practical terms. Already the first steps clearly showed an imperfection of existing technologies, managerial and regulatory schemes; lack of qualified specialists, relevant methods and techniques; uncertainties in methodology of decision-making, etc. Thus, building up (or maybe, structuring) of special scientific and technological basis, which the authors call ''engineering radioecology'', seems to be an important task. In this paper they endeavored to substantiate the last thesis and to suggest some preliminary ideas concerning the subject matter of engineering radioecology

    Full Text Available After the theoric seasons of the second middle of the Twenthieth century especially by the anglo-american Scholars and the beginning of the open area excavations enterprises in Italy thirty years ago, the concept of the therm “method” holds now a multiplicity of aspects one another connected; their theorical and practical applications make valuable the method universality but it depends on the characteristics of the archaeological site too. So Nora with its historical-archaeological stratification is an exemplary specimen from a lot of points of view like a precious source to draw stratigraphical sequences inside  large chronological oasis with very important monumental contexts. The universitary équipes were allowed to adopt a modern methodological practice, founded on technological resources, that leads to a perspective which contains the archaeology of architecture and the archaeology of the smallest clue compared together. The fast and careful editions of the field-works in the “Quaderni Norensi” Collection, enriched by an exhaustive documentary evidence, constitutes an indispensable contribution to the reconstruction of the ancient town and the best trial to test a research model “open-area” between équipes differently formed but in a scientific homogeneous climate.

    Searching for life in astromaterials to be delivered from the future missions to extraterrestrial bodies is undoubtedly related to studies of the properties and signatures of living microbial cells and microfossils on Earth. As model terrestrial analogs of Martian polar subsurface layers are often regarded the Antarctic glacier and Earth permafrost habitats where alive microbial cells preserved viability for millennia years due to entering the anabiotic state. For the future findings of viable microorganisms in samples from extraterrestrial objects, it is important to use a combined methodology that includes classical microbiological methods, plating onto nutrient media, direct epifluorescence and electron microscopy examinations, detection of the elemental composition of cells, radiolabeling techniques, PCR and FISH methods. Of great importance is to ensure authenticity of microorganisms (if any in studied samples) and to standardize the protocols used to minimize a risk of external contamination. Although the convincing evidence of extraterrestrial microbial life will may come from the discovery of living cells in astromaterials, biomorphs and microfossils must also be regarded as a target in search of life evidence bearing in mind a scenario that alive microorganisms had not be preserved and underwent mineralization. Under the laboratory conditions, processes that accompanied fossilization of cyanobacteria were reconstructed, and artificially produced cyanobacterial stromatolites resembles by their morphological properties those found in natural Earth habitats. Regarding the vital importance of distinguishing between biogenic and abiogenic signatures and between living and fossil microorganisms in analyzed samples, it is worthwhile to use some previously developed approaches based on electron microscopy examinations and analysis of elemental composition of biomorphs in situ and comparison with the analogous data obtained for laboratory microbial cultures and

São bens fundamentais aqueles cujo acesso é garantido a todos e a cada um, visto que são objetos dos direitos fundamentais subtraídos à lógica do mercado. A garantia de novos bens como bens fundamentais exige uma decisão política civilizatória de submeter ao direito as relações de mercado. Assim, às cartas e convenções internacionais e constitucionais de direitos fundamentais deveriam ser acrescentadas Cartas Constitucionais e Cartas Internacionais de bens fundamentais. Daí a necessidade de uma nova dimensão do constitucionalismo garantista: a longo prazo, além de global, para além da lógica individualista dos direitos e da miopia, e do estreito localismo da política das democracias nacionais.AbstractThis article addresses the question of whether the stipulation of fundamental rights and obligations and prohibitions related to them is sufficient to properly ensure the needs and vital interests, especially those from collective interest. Fundamental goods are those whose access is guaranteed to each and every one since they are the object of fundamental rights, excluded from the logic of the market. The warranty for new goods and basic goods in the bottom of civilization requires a political decision to submit the right market relations. Thus, to the international charters and conventions and fundamental constitutional rights should be added Charters and international charter of basic goods. Hence the need for a new dimension of the constitutionally guaranteed: a constitutionally guaranteed in the long term, and global, apart from the individualistic logic of rights and shortsightedness and narrow localism policy of national democracies.

    Que a teoria a uma coisa e a prática outra, a uma idéia que tem 'a pele dura', como dizem os franceses. Uma das causas da longevidade desse preconceito a que faltam obras mediadoras, não só na area da tradução que nos ocupa aqui. A teoria pede muitas experiências para guiar o tratamento de um problema concreto e as obras centradas na prática, pedem demasiado poder de extrapolação para servir a casos não explicitados.

    Full Text Available O fenômeno explosivo da Internet, insuspeitado há 10 anos, e que hoje se expande de modo acelerado e abrangente em todas as atividades humanas, tem impactos relevantes também na contabilidade. A interatividade, como característica da nova forma de comunicação inaugurada com a Internet, apresenta desafios ao Sistema Contábil Gerencial, cujas respostas, na forma de uma visão interativa da empresa, do patrimônio e do processo de gestão, se expressam na abordagem do Sistema de Gestão Econômica. As insuficiências da Contabilidade Financeira em expressar a realidade das empresas da nova economia no mercado de capitais são igualmente identificadas. Ao mesmo tempo, são comentadas as oportunidades que se abrem à contabilidade financeira, com a divulgação das demonstrações mediante os recursos de linguagem da Internet, com base nos projetos desenvolvidos por entidades reguladoras, particularmente pelo International Accounting Standards Committee (IASC. Com o incremento da comunicação contábil interativa via Internet e com o aprofundamento do debate sobre a contabilização das empresas de ativos intelectuais intensivos, como as da nova economia, preconiza-se, sob a égide da interatividade, uma renovação da Contabilidade Financeira e sua maior aproximação da Contabilidade Gerencial, com base nos fundamentos da Teoria Contábil.The explosive phenomenon of the Internet, which was unsuspected ten years ago, and is now expanding in an accelerating and involving way in all human activities, has a relevant impact on accounting as well. Interactivity - one characteristic of the new communication form that was inaugurated by the Internet - raises challenges for the Management Accounting System, whose answers, in the form of an interactive view of the enterprise, its assets and its managing process, are expressed in the approach of the Economic Management System.

    2012-01-17

    A comprehensive methodology has been created to quantify the degree of criticality of the metals of the periodic table. In this paper, we present and discuss the methodology, which is comprised of three dimensions: supply risk, environmental implications, and vulnerability to supply restriction. Supply risk differs with the time scale (medium or long), and at its more complex involves several components, themselves composed of a number of distinct indicators drawn from readily available peer-reviewed indexes and public information. Vulnerability to supply restriction differs with the organizational level (i.e., global, national, and corporate). The criticality methodology, an enhancement of a United States National Research Council template, is designed to help corporate, national, and global stakeholders conduct risk evaluation and to inform resource utilization and strategic decision-making. Although we believe our methodological choices lead to the most robust results, the framework has been constructed to permit flexibility by the user. Specific indicators can be deleted or added as desired and weighted as the user deems appropriate. The value of each indicator will evolve over time, and our future research will focus on this evolution. The methodology has proven to be sufficiently robust as to make it applicable across the entire spectrum of metals and organizational levels and provides a structural approach that reflects the multifaceted factors influencing the availability of metals in the 21st century.

  11. Unattended Monitoring System Design Methodology

    International Nuclear Information System (INIS)

    A methodology for designing Unattended Monitoring Systems starting at a systems level has been developed at Sandia National Laboratories. This proven methodology provides a template that describes the process for selecting and applying appropriate technologies to meet unattended system requirements, as well as providing a framework for development of both training courses and workshops associated with unattended monitoring. The design and implementation of unattended monitoring systems is generally intended to respond to some form of policy based requirements resulting from international agreements or domestic regulations. Once the monitoring requirements are established, a review of the associated process and its related facilities enables identification of strategic monitoring locations and development of a conceptual system design. The detailed design effort results in the definition of detection components as well as the supporting communications network and data management scheme. The data analyses then enables a coherent display of the knowledge generated during the monitoring effort. The resultant knowledge is then compared to the original system objectives to ensure that the design adequately addresses the fundamental principles stated in the policy agreements. Implementation of this design methodology will ensure that comprehensive unattended monitoring system designs provide appropriate answers to those critical questions imposed by specific agreements or regulations. This paper describes the main features of the methodology and discusses how it can be applied in real world situations

    Full Text Available Procurou-se, neste trabalho, pensar o tempo no contexto das ciências da saúde, no qual se entrelaçam aspectos físicos, biológicos, psicológicos e sociológicos. Enquanto em nossa percepção do mundo e de nós mesmos o tempo se apresenta sob muitas facetas, na física clássica, conforme o modelo newtoniano, assumia-se a existência de um tempo absoluto, unilinear, homogêneo e independente do observador. Com a teoria da relatividade e o estudo dos sistemas complexos, um novo conceito de tempo apresenta-se na física: o tempo fractal, o qual possibilita maior compatibilidade com as abordagens psicológicas e sociológicas. Nesta perspectiva, a experiência de vida de uma pessoa, e seus respectivos processos de construção da saúde, envolveria uma multiplicidade de tempos, que coexistem e se organizam segundo um padrão coerente de auto-similaridade. Uma quebra desse padrão estaria correlacionada com a ocorrência da doença. Sugere-se que uma abordagem mais adequada do adoecimento deveria levar em conta, como referência para o profissional de saúde, o conceito de tempo fractal, possibilitando maior sintonia do paciente com a complexidade da natureza e, por conseguinte, consigo mesmo.

    Full Text Available The way in which Strategic planning is designed is different depending on the organization. For that reason, no standard procedures can be given to develop Strategic planning. However, the scenarios analysis method is used in any field or organization. We could define a scenario as a set of variables or events that describes a future situation. Additionally, the continuous irruption of new technologies invites us to carry out a revision of the old methodologies and procedures with the intention of starting an innovation process to make them more efficient. The challenge presented in this article consists of the use of the agents technology within a new methodological approach to envisionfuture possible scenarios more quickly and more accurately than the classical methods we currently use.

    Lean manufacturing is a systematic method of identifying and eliminating waste. Use of Lean manufacturing techniques at the IBM photomask manufacturing facility has increased efficiency and productivity of the photomask process. Tools, such as, value stream mapping, 5S and structured problem solving are widely used today. In this paper we describe a step-by-step Lean technique used to systematically decrease defects resulting in reduced material costs, inspection costs and cycle time. The method used consists of an 8-step approach commonly referred to as the 8D problem solving process. This process allowed us to identify both prominent issues as well as more subtle problems requiring in depth investigation. The methodology used is flexible and can be applied to numerous situations. Advantages to Lean methodology are also discussed.

    We describe the software requirements and development methodology developed for the NLC control system. Given the longevity of that project, and the likely geographical distribution of the collaborating engineers, the planned requirements management process is somewhat more formal than the norm in high energy physics projects. The short term goals of the requirements process are to accurately estimate costs, to decompose the problem, and to determine likely technologies. The long term goal is to enable a smooth transition from high level functional requirements to specific subsystem and component requirements for individual programmers, and to support distributed development. The methodology covers both ends of that life cycle. It covers both the analytical and documentary tools for software engineering, and project management support.

  6. AGR core safety assessment methodologies

    International Nuclear Information System (INIS)

    To demonstrate the safety of its gas-cooled graphite-moderated AGR reactors, nuclear safety assessments of the cores are based upon a methodology which demonstrates no component failures, geometrical stability of the structure and material properties bounded by a database. All AGRs continue to meet these three criteria. However, predictions of future core behaviour indicate that the safety case methodology will eventually need to be modified to deal with new phenomena. A new approach to the safety assessment of the cores is currently under development, which can take account of these factors while at the same time providing the same level of protection for the cores. This approach will be based on the functionality of the core: unhindered movement of control rods, continued adequate cooling of the fuel and the core, continued ability to charge and discharge fuel.

    Recently, the use of ultrasonic and microwave has attracted considerable interest as an alternative approach to the traditional extraction methods. In this paper, in order to maximize the yield and purity of polysaccharides from Inonotus obliquus, response surface methodology (RSM) was employed to optimize the ultrasonic/microwave assisted extraction (UMAE) conditions. The results indicated that the optimal conditions for UMAE were 90W microwave power, 50W ultrasonic power together with 40kHz ultrasonic frequency, solid/water ratio was 1:20 (W/V) and the extracting time was 19min, respectively. Under the optimal conditions, the yield and purity of polysaccharides were 3.25% and 73.16%, respectively, which are above that of traditional hot water extraction and close to the predicted value (3.07% and 72.54%, respectively). These results confirmed that ultrasonic/microwave assisted extraction (UMAE) of polysaccharides had great potential and efficiency compared with traditional hot water extraction. At the same time, the anti-tumor activities of the polysaccharides from I. obliquus with UMAE were evaluated. The results suggested that polysaccharides from I. obliquus exhibited obvious anti-tumor activities. PMID:20149817

  13. Implementation impacts of PRL methodology

    International Nuclear Information System (INIS)

    This report responds to a DOE-SR request to evaluate the impacts from implementation of the proposed Plutonium Recovery Limit (PRL) methodology. The PRL Methodology is based on cost minimization for decisions to discard or recover plutonium contained in scrap, residues, and other plutonium bearing materials. Implementation of the PRL methodology may result in decisions to declare as waste certain plutonium bearing materials originally considered to be a recoverable plutonium product. Such decisions may have regulatory impacts, because any material declared to be waste would immediately be subject to provisions of the Resource Conservation and Recovery Act (RCRA). The decision to discard these materials will have impacts on waste storage, treatment, and disposal facilities. Current plans for the de-inventory of plutonium processing facilities have identified certain materials as candidates for discard based upon the economic considerations associated with extending the operating schedules for recovery of the contained plutonium versus potential waste disposal costs. This report evaluates the impacts of discarding those materials as proposed by the F Area De-Inventory Plan and compares the De-Inventory Plan assessments with conclusions from application of the PRL. The impact analysis was performed for those materials proposed as potential candidates for discard by the De-Inventory Plan. The De-Inventory Plan identified 433 items, containing approximately 1% of the current SRS Pu-239 inventory, as not appropriate for recovery as the site moves to complete the mission of F-Canyon and FB-Line. The materials were entered into storage awaiting recovery as product under the Department's previous Economic Discard Limit (EDL) methodology which valued plutonium at its incremental cost of production in reactors. An application of Departmental PRLs to the subject 433 items revealed that approximately 40% of them would continue to be potentially recoverable as product plutonium

    This Methodology Booklet provides a comprehensive review and methodology guiding principles for constructing energy efficiency indicators, with illustrative examples of application to individual countries. It reviews work done by international agencies and national government in constructing meaningful energy efficiency indicators that help policy makers to assess changes in energy efficiency over time. Building on past OECD experience and best practices, and the knowledge of these countries' institutions, relevant sources of information to construct an energy indicator database are identified. A framework based on levels of hierarchy of indicators -- spanning from aggregate, macro level to disaggregated end-use level metrics -- is presented to help shape the understanding of assessing energy efficiency. In each sector of activity: industry, commercial, residential, agriculture and transport, indicators are presented and recommendations to distinguish the different factors affecting energy use are highlighted. The methodology booklet addresses specifically issues that are relevant to developing indicators where activity is a major factor driving energy demand. A companion spreadsheet tool is available upon request.

    International Nuclear Information System (INIS)

    The work described in this report has been performed as a part of the RESTRAT Project FI4P-CT95-0021a (PL 950128) co-funded by the Nuclear Fission Safety Programme of the European Commission. The RESTRAT project has the overall objective of developing generic methodologies for ranking restoration techniques as a function of contamination and site characteristics. The project includes analyses of existing remediation methodologies and contaminated sites, and is structured in the following steps: characterisation of relevant contaminated sites; identification and characterisation of relevant restoration techniques; assessment of the radiological impact; development and application of a selection methodology for restoration options; formulation of generic conclusions and development of a manual. The project is intended to apply to situations in which sites with nuclear installations have been contaminated with radioactive materials as a result of the operation of these installations. The areas considered for remedial measures include contaminated land areas, rivers and sediments in rivers, lakes, and sea areas. Five contaminated European sites have been studied. Various remedial measures have been envisaged with respect to the optimisation of the protection of the populations being exposed to the radionuclides at the sites. Cost-benefit analysis and multi-attribute utility analysis have been applied for optimisation. Health, economic and social attributes have been included and weighting factors for the different attributes have been determined by the use of scaling constants. (au)

    1993-01-01

    Over the years many engineering disciplines have developed, including chemical, electronic, etc. Common to all engineering disciplines is the use of rigor, models, metrics, and predefined methodologies. Recently, a new engineering discipline has appeared on the scene, called software engineering. For over thirty years computer software has been developed and the track record has not been good. Software development projects often miss schedules, are over budget, do not give the user what is wanted, and produce defects. One estimate is there are one to three defects per 1000 lines of deployed code. More and more systems are requiring larger and more complex software for support. As this requirement grows, the software development problems grow exponentially. It is believed that software quality can be improved by applying engineering principles. Another compelling reason to bring the engineering disciplines to software development is productivity. It has been estimated that productivity of producing software has only increased one to two percent a year in the last thirty years. Ironically, the computer and its software have contributed significantly to the industry-wide productivity, but computer professionals have done a poor job of using the computer to do their job. Engineering disciplines and methodologies are now emerging supported by software tools that address the problems of software development. This paper addresses some of the current software engineering methodologies as a backdrop for the general evaluation of computer assisted software engineering (CASE) tools from actual installation of and experimentation with some specific tools.

    Event Tree(ET)/Fault Tree(FT) are significant methodology in Probabilistic Safety Assessment(PSA) for Nuclear Power Plants(NPPs). ET/FT methodology has the advantage for users to be able to easily learn and model. It enables better communication between engineers engaged in the same field. However, conventional methodologies are difficult to cope with the dynamic behavior (e.g. operation mode changes or sequence-dependent failure) and integrated situation of mechanical failure and human errors. Meanwhile, new possibilities are coming for the improved PSA by virtue of the dramatic development on digital hardware, software, information technology, and data analysis.. More specifically, the computing environment has been greatly improved with being compared to the past, so we are able to conduct risk analysis with the large amount of data actually available. One method which can take the technological advantages aforementioned should be the dynamic PSA such that conventional ET/FT can have time- and condition-dependent behaviors in accident scenarios. In this paper, we investigated the various enabling techniques for the dynamic PSA. Even though its history and academic achievement was great, it seems less interesting from industrial and regulatory viewpoint. Authors expect this can contribute to better understanding of dynamic PSA in terms of algorithm, practice, and applicability. In paper, the overview for the dynamic PSA was conducted. Most of methodologies share similar concepts. Among them, DDET seems a backbone for most of methodologies since it can be applied to large problems. The common characteristics sharing the concept of DDET are as follows: • Both deterministic and stochastic approaches • Improves the identification of PSA success criteria • Helps to limit detrimental effects of sequence binning (normally adopted in PSA) • Helps to avoid defining non-optimal success criteria that may distort the risk • Framework for comprehensively considering

    Full text of publication follows: a quantitative methodology is developed, based on the concepts of hierarchy and synthesis, to integrate and organize information and data. The methodology uses scaling to synthesize experimental data and analytical results, and to provide quantitative criteria for evaluating the effects of various design and operating parameters that influence processes in a complex system such as a nuclear power plant or a related test facility. Synthesis and scaling are performed on three hierarchical levels: the process, component and system levels. Scaling on the process level determines the effect of a selected process on a particular state variable during a selected scenario. At the component level this scaling determines the effects various processes have on a state variable, and it ranks the processes according to their importance by the magnitude of the fractional change they cause on that state variable. At the system level the scaling determines the governing processes and corresponding components, ranking these in the order of importance according to their effect on the fractional change of system-wide state variables. The scaling methodology reveals on all levels the fractional change of state variables and is called therefore the Fractional Scaling Methodology (FSM). FSM synthesizes process parameters and assigns to each thermohydraulic process a dimensionless effect metric {omega} = {omega}t, that is the product of the specific rate of fractional change {omega} and the characteristic time t. The rate of fractional change {omega} is the ratio of process transport rate over content of a preserved quantity in a component. The effect metric {omega} quantifies the contribution of the process to the fractional change of a state variable in a given component. Ordering of a component effect metrics provides the hierarchy of processes in a component, then in all components and the system. FSM separates quantitatively dominant from minor

    Full Text Available Entre os anos de 1971 e 1973, ocorreu na área central da cidade do Recife uma das mais incisivas intervenções urbanas, com a abertura, o prolongamento e o alargamento da Av. Dantas Barreto no trecho compreendido entre o pátio da Igreja N. S. do Carmo e a Praça Sérgio Loreto, atingindo uma área de quase 4 km2. A justificada para a obra era a necessidade de buscar uma solução capaz de enfrentar o cenário caótico do tráfego de veículos na parte central da cidade e possibilitar uma ligação direta e fluente entre o centro e a zona sul da cidade. A execução dessa obra implicou na demolição do casario de feições coloniais e da Igreja do Bom Jesus dos Martírios, construída entre 1791 e 1796. Os defensores da preservação da Igreja exigiam o seu tombamento como um bem histórico-cultural, pois ela era a única igreja do Brasil totalmente edificada por escravos no Brasil. Esse posicionamento suscitou um embate que foi denominado pelo historiador Denis Bernardes como a “A Batalha dos Martírios”, desvelando no seu decurso a lógica modernizante, fundada nos critérios de uma sociedade típica do capitalismo tardio, que orientou a construção da Av. Dantas Barreto e as políticas municipais no período, possibilitando-nos averiguar, dessa forma, a natureza dos embates suscitados e os seus desdobramentos em seu contexto histórico.

    Full Text Available This paper is a theoretical essay focused on the conceptual relations of ecotourism in the process of globalization and the contradictions involving economic growth and development. In the methodological procedures rose the following hypothesis: community-based ecotourism is an ally of the construction of the development of local peoples. It had been worked on issues such as the involvement of social economy, community tourism and ecotourism in the prospect of collaborating with the insertion of the local community in tourism. In this context, this work addresses issues ofcommunity-based ecotourism, questioning the development imperative in the formation of well-being of humans and also noting its benefits to the local community.

  14. Radioisotope methodology course radioprotection aspects

    International Nuclear Information System (INIS)

    The advancement knowledge in molecular and cell biology, biochemistry, medicine and pharmacology, which has taken place during the last 50 years, after World War II finalization, is really outstanding. It can be safely said that this fact is principally due to the application of radioisotope techniques. The research on metabolisms, biodistribution of pharmaceuticals, pharmacodynamics, etc., is mostly carried out by means of techniques employing radioactive materials. Radioisotopes and radiation are frequently used in medicine both as diagnostic and therapeutic tools. The radioimmunoanalysis is today a routine method in endocrinology and in general clinical medicine. The receptor determination and characterization is a steadily growing methodology used in clinical biochemistry, pharmacology and medicine. The use of radiopharmaceuticals and radiation of different origins, for therapeutic purposes, should not be overlooked. For these reasons, the importance to teach radioisotope methodology is steadily growing. This is principally the case for specialization at the post-graduate level but at the pre graduate curriculum it is worthwhile to give some elementary theoretical and practical notions on this subject. These observations are justified by a more than 30 years teaching experience at both levels at the School of Pharmacy and Biochemistry of the University of Buenos Aires, Argentina. In 1960 we began to teach Physics III, an obligatory pregraduate course for biochemistry students, in which some elementary notions of radioactivity and measurement techniques were given. Successive modifications of the biochemistry pregraduate curriculum incorporated radiochemistry as an elective subject and since 1978, radioisotope methodology, as obligatory subject for biochemistry students. This subject is given at the radioisotope laboratory during the first semester of each year and its objective is to provide theoretical and practical knowledge to the biochemistry students, even

    Full Text Available Comprehensive System of Rorschach interpretation is considered as nomotetic system that makes possible using of projective method in research projects. However, research use of Rorschach method besides of appropriate knowledge of assign procedures and interpretation rules, means a knowledge of specific methodological issues. The Rorschach indicators are nor independent, as they are a part of specific net, so in some research it is necessary to control basic variables not to get artifacts in our research. This is basically relied on researches where we compare groups, as well as in normative studies where through cross-cultural we compare Rorschach indicators. .

  19. Applying UPC Scaling-Up Methodology to the LSTF-PKL Counterpart Test

    Directory of Open Access Journals (Sweden)

    2014-01-01

    Full Text Available In the framework of the nodalization qualification process and quality guarantee procedures and following the guidelines of Kv-scaled analysis and UMAE methodology, further development has been performed by UPC team resulting in a scaling-up methodology. Such methodology has been applied in this paper for analyzing discrepancies that appear between the simulations of two counterpart tests. It allows the analysis of scaling-down criterion used for the design of an ITF and also the investigation of the differences of configuration between an ITF and a particular NPP. For analyzing both, it applies two concepts “scaled-up nodalizations” and “hybrid nodalizations.” The result of this activity is the explanation of appeared distortions and its final goal is to qualify nodalizations for their use in the analysis of equivalent scenarios at an NPP scale. In this sense, the experimental data obtained in the OECD/NEA PKL-2 and ROSA-2 projects as counterpart test are of a great value for the testing of the present methodology. The results of the posttest calculations of LSTF-PKL counterpart tests have allowed the analyst to define which phenomena could be well reproduced by their nodalizations and which not, in this way establishing the basis for a future extrapolation to an NPP scaled calculation. The application of the UPC scaling up methodology has demonstrated that selected phenomena can be scaled-up and explained between counterpart simulations by carefully considering the differences in scale and design.

    Full Text Available O livro A Bíblia Hebraica como obra aberta foi originalmente concebido como uma tese de doutorado defendida por Eliana Branco Malanga, em 2002, no programa de Língua Hebraica, Literatura e Cultura Judaicas da faculdade de Letras da Universidade de São Paulo. O estudo de Malanga visa a, basicamente, verificar as possibilidades de se extender o conceito de “obra aberta”, cunhado por Umberto Eco, para uma leitura da Bíblia Hebraica. Esse conceito, tomado da teoria semiológica, compreende a designação das obras de arte que admitem “múltiplas possibilidades de decodificação em virtude da densidade de significados” que possuem (p. 19. A abertura das interpretações do texto bíblico, no entanto, parecem extrapolar os limites estruturais e permite o reconhecimento dessa abertura em um sentido muito mais amplo.

  8. Methodologic frontiers in environmental epidemiology.

    Science.gov (United States)

    Rothman, K J

    1993-01-01

    Environmental epidemiology comprises the epidemiologic study of those environmental factors that are outside the immediate control of the individual. Exposures of interest to environmental epidemiologists include air pollution, water pollution, occupational exposure to physical and chemical agents, as well as psychosocial elements of environmental concern. The main methodologic problem in environmental epidemiology is exposure assessment, a problem that extends through all of epidemiologic research but looms as a towering obstacle in environmental epidemiology. One of the most promising developments in improving exposure assessment in environmental epidemiology is to find exposure biomarkers, which could serve as built-in dosimeters that reflect the biologic footprint left behind by environmental exposures. Beyond exposure assessment, epidemiologists studying environmental exposures face the difficulty of studying small effects that may be distorted by confounding that eludes easy control. This challenge may prompt reliance on new study designs, such as two-stage designs in which exposure and disease information are collected in the first stage, and covariate information is collected on a subset of subjects in state two. While the analytic methods already available for environmental epidemiology are powerful, analytic methods for ecologic studies need further development. This workshop outlines the range of methodologic issues that environmental epidemiologists must address so that their work meets the goals set by scientists and society at large. PMID:8206029

O fluxo de calor latente de evaporação utilizou a maior porção da energia disponível no sistema, sendo uma função direta da disponibilidade hídrica no solo. O fluxo de calor sensível foi o segundo termo no consumo de energia disponível, variando segundo uma função inversa da disponibilidade hídrica. O fluxo de calor no solo variou inversamente ao índice de área foliar, utilizando a menor fração do saldo de radiação. Em geral, os fluxos de calor sensível no ar e no solo foram positivos somente nas primeiras horas da manhã e ao final da tarde. Em alguns horários houve aporte de energia por advecção, invertendo o gradiente térmico vertical do ar e incrementando o fluxo de calor latente de evaporação.

    Full Text Available Constata-se que boa parte dos comentadores da obra de Piaget afirma que a inteligência é originariamente de natureza individual e que, portanto, a socialização seria o efeito de um processo de evolução cognitiva. Essa interpretação substancializa a inteligência, recorre a explicações redu-cionistas e considera o processo de construção epistêmica como uma simples atualização de possíveis cognitivos pré-formados. Uma série de investigações tem sugerido a existência de uma interdependência causal entre as dinâmicas sociais e o desenvolvimento cognitivo, que nos alerta da necessidade de rediscutir o estatuto da interação.A great many commentators on Piaget’s work nowadays, still take it for granted that intelligence is of an individual nature, and therefore that its socialization is nothing but a mere effect of the cognitive evolution process. This interpretation consists of substantializing intelligence, resorting to reductional explanations and considers the epistemological constructive process a simple actualization of possible pre-established cognitives. A series of investigations have suggested the existence of a casual interdependence within social dynamics and the cognitive development. These researches call attention to the necessity of re-discussion on the status of interaction.

Minha hipótese é a de que o utilitarismo esvazia os seres humanos de suas motivações para oferecer uma imagem opaca do agente moral. Por isso, ele é incapaz de solucionar dilemas morais que envolvem, por um lado, o autossacrifício por razões afetivas e, por outro, conflitos que opõem culturas distintas. Meu ponto é que não é necessariamente imoral a ação de um agente o qual sacrifica a solução ótima (proposta pelo cálculo utilitário e que privilegia a maioria, em nome de uma motivação afetiva, que julga que uma vida pode valer mais do que outra, nem o sofrimento é necessariamente imoral em todas as culturas de modo uniforme.

    Full Text Available A debênture vem se tornando um instrumento de captação cada vez mais importante para empresas não financeiras no mercado brasileiro e uma alternativa às elevadas taxas de juros cobradas pelos bancos comerciais em uma operação de financiamento. Um aspecto-chave para o desenvolvimento do mercado secundário deste instrumento é o correto tratamento do risco de crédito, que ocorre quando o emissor não cumpre suas obrigações contratuais. Este trabalho propõe e testa uma metodologia que determina a magnitude deste risco para uma carteira de debêntures de empresas emissoras brasileiras. A abordagem utilizada baseia-se no Modelo de Merton (1974 para bônus corporativos, que utiliza as fórmulas de Black-Scholes para o cálculo do preço de opções. Também são utilizadas técnicas de otimização para a determinação do risco da carteira. Adotando um modelo simples e de baixo custo computacional, chegamos a uma medida de risco mais conservadora do que a obtida com o tradicional modelo VaR (value at risk. Além disso, apresentamos uma metodologia para a obtenção da composição ótima da carteira de debêntures.The debenture (corporate bond is considered a fantastic financial instrument in terms of funding for the non-financial firms in the Brazilian market.

This paper proposes and tests a methodology to quantify this risk in a cross-section of Brazilian debentures. Our approach is based on Merton’s (1974 asset pricing model that uses the Black-Schole’s put option formula. The consequent optimization techniques allow us to infer the risk of debentures. By using a simple and low-cost model, we find a risk measure that is more conservative than the usual VaR (value at

    Full Text Available All large projects, from their inception to their completion, follow certain procedures, when undergoing evaluations of different designs, while at the same time, assuring project functionality at realistic costs which are acceptable to the owner. To keep project costs within certain parameters, there is a need to begin the project with a realistic budget and to have some reliable pricing data. In addition, during the development phase, the project cost must be recalculated and, if necessary, readjusted. Another way to increase the project value or to decrease the cost is to perform Value Engineering, i.e. an analysis of project functionality, specifications, tender documents and other project aspects by a team of experts.This paper describes Value Engineering and how such experts’ efforts would be applied and benefit transportation projects. The methodology of design of logistics terminal is presented, including related transport network as an example of a large transport project for the use of Value Engineering.

  1. Inventory differences: An evaluation methodology

    International Nuclear Information System (INIS)

    This paper discusses an evaluation methodology which is used for inventory differences at the Los Alamos National Laboratory. It is recognized that there are various methods which can be, and are being, used to evaluate process inventory differences at DOE facilities. The purpose of this paper is to share our thoughts on the subject and our techniques with those who are responsible for the evaluation of inventory differences at their facility. One of the most dangerous aspects of any evaluation technique, especially one as complex as most inventory difference evaluations tend to be, is to fail to look at the tools being used as indicators. There is a tendency to look at the results of an evaluation by one technique as an absolute. At the Los Alamos National Laboratory, several tools are used and the final evaluation is based on a combination of the observed results of a many-faceted evaluation. The tools used and some examples are presented

    2012-08-01

    Full Text Available The paper analyses forwarding performance of IPsec gateway over the rage of offered loads. It focuses on the forwarding rate and packet loss particularly at the gateway’s performance peak and at the state of gateway’s overload. It explains possible performance degradation when the gateway is overloaded by excessive offered load. The paper further evaluates different approaches for obtaining forwarding performance parameters – a widely used throughput described in RFC 1242, maximum forwarding rate with zero packet loss and us proposed equilibrium throughput. According to our observations equilibrium throughput might be the most universal parameter for benchmarking security gateways as the others may be dependent on the duration of test trials. Employing equilibrium throughput would also greatly shorten the time required for benchmarking. Lastly, the paper presents methodology and a hybrid step/binary search algorithm for obtaining value of equilibrium throughput.

  3. Methodology for flammable gas evaluations

    Energy Technology Data Exchange (ETDEWEB)

    Hopkins, J.D., Westinghouse Hanford

    1996-06-12

    There are 177 radioactive waste storage tanks at the Hanford Site. The waste generates flammable gases. The waste releases gas continuously, but in some tanks the waste has shown a tendency to trap these flammable gases. When enough gas is trapped in a tank`s waste matrix, it may be released in a way that renders part or all of the tank atmosphere flammable for a period of time. Tanks must be evaluated against previously defined criteria to determine whether they can present a flammable gas hazard. This document presents the methodology for evaluating tanks in two areas of concern in the tank headspace:steady-state flammable-gas concentration resulting from continuous release, and concentration resulting from an episodic gas release.

The rankings of best global brands are different, depending on the company which elaborated them. The brand valuation methods are subject to a standard and some guideline notes, but they represent rather a niche for these companies of brand rankings. The brand value which contains future aspects, combined with difficulties in the valuation of the intangible assets of brands, analysed in a dynamic and complex global framework, becomes very difficult to be estimated. Brand owners and investors are interested in the brand potential value, considered to be the creative value force on markets. The paper brings forth some common aspects and some criticism of brand valuation methodologies and practices. Some questions about the credibility of the ranking lists of best global brands arise.

    Lightning is a safety hazard for high-explosives (HE) and their detonators. In the However, the current flowing from the strike point through the rebar of the building The methodology for estimating the risk from indirect lighting effects will be presented. It has two parts: a method to determine the likelihood of a detonation given a lightning strike, and an approach for estimating the likelihood of a strike. The results of these two parts produce an overall probability of a detonation. The probability calculations are complex for five reasons: (1) lightning strikes are stochastic and relatively rare, (2) the quality of the Faraday cage varies from one facility to the next, (3) RF coupling is inherently a complex subject, (4) performance data for abnormally stressed detonators is scarce, and (5) the arc plasma physics is not well understood. Therefore, a rigorous mathematical analysis would be too complex. Instead, our methodology takes a more practical approach combining rigorous mathematical calculations where possible with empirical data when necessary. Where there is uncertainty, we compensate with conservative approximations. The goal is to determine a conservative estimate of the odds of a detonation. In Section 2, the methodology will be explained. This report will discuss topics at a high-level. The reasons for selecting an approach will be justified. For those interested in technical details, references will be provided. In Section 3, a simple hypothetical example will be given to reinforce the concepts. While the methodology will touch on all the items shown in Figure 1, the focus of this report is the indirect effect, i.e., determining the odds of a detonation from given EM fields. Professor Martin Uman from the University of Florida has been characterizing and defining extreme lightning strikes. Using Professor Uman's research, Dr. Kimball Merewether at Sandia National Laboratory in Albuquerque calculated the EM fields inside a Faraday-cage type

  7. New methodology in biomedical science: methodological errors in classical science.

    Science.gov (United States)

    Skurvydas, Albertas

    2005-01-01

    The following methodological errors are observed in biomedical sciences: paradigmatic ones; those of exaggerated search for certainty; science dehumanisation; deterministic and linearity; those of making conclusions; errors of reductionism or quality decomposition as well as exaggerated enlargement; errors connected with discarding odd; unexpected or awkward facts; those of exaggerated mathematization; isolation of science; the error of "common sense"; Ceteris Paribus law's ("other things being equal" laws) error; "youth" and common sense; inflexibility of criteria of the truth; errors of restricting the sources of truth and ways of searching for truth; the error connected with wisdom gained post factum; the errors of wrong interpretation of research mission; "laziness" to repeat the experiment as well as the errors of coordination of errors. One of the basic aims for the present-day scholars of biomedicine is, therefore, mastering the new non-linear, holistic, complex way of thinking that will, undoubtedly, enable one to make less errors doing research. The aim of "scientific travelling" will be achieved with greater probability if the "travelling" itself is performed with great probability. PMID:15687745

  10. Methodology for setting cleanup criteria

    International Nuclear Information System (INIS)

    The U.S. Department of Energy (DOE) has developed guidance for establishing cleanup criteria or authorized limits for sites containing residual radioactive material. The DOE requires that the as-low-as-reasonably-achievable (ALARA) process be applied. This process results in the development of cleanup levels that are as low as practicable giving due consideration to health, environment, economics, cultural, and natural resources and other factors. The process employs a cost-benefit optimization analysis and, where appropriate and feasible, considers multiple attributes. Frequently, some important factors or attributes do not lend themselves to quantification in a cost-benefit study and therefore must be considered qualitatively in the process. While the cost-benefit analysis is not the only consideration, it is an important clement in the establishment of cleanup criteria and selection of remedial alternatives. Key to the cost-benefit process is the relation between cleanup level and dose. This is determined through pathway analysis methodology. This paper discusses the pathway analysis process and will cover radiologically and nonradiologically contaminated sites and building contamination

  17. Methodology of site protection studies

    International Nuclear Information System (INIS)

    Preliminary studies preceding building of a nuclear facility aim at assessing the choice of a site and establishing operating and control procedures. These studies are of two types. Studies on the impact of environment on the nuclear facility to be constructed form one type and studies on the impact of nuclear facilities on the environment form the second type. A methodology giving a framework to studies of second type is presented. These studies are undertaken to choose suitable sites for nuclear facilities. After a preliminary selection of a site based on the first estimate, a detailed site study is undertaken. The procedure for this consists of five successive phases, namely, (1) an inquiry assessing the initial state of the site, (2) an initial synthesis of accumulated information for assessing the health and safety consequences of releases, (3) laboratory and field studies simulating the movement of waste products for a quantitative assessment of effects, (4) final synthesis for laying down the release limits and radiological control methods, and (5) conclusions based on comparing the data of final synthesis to the limits prescribed by regulations. These five phases are outlined. Role of periodic reassessments after the facility is in operation for same time is explained. (M.G.B.)

    Full Text Available The paper is aimed at depicting the ISDF software development methodology by emphasizing quality management and software development lifecycle. The ISDF methodology was built especially for innovative software development projects. The ISDF methodology was developed empirically by trial and error in the process of implementing multiple innovative projects. The research process began by analysing key concepts like innovation and software development and by settling the important dilemma of what makes a web application innovative. Innovation in software development is presented from the end-user, project owner and project manager’s point of view. The main components of a software development methodology are identified. Thus a software development methodology should account for people, roles, skills, teams, tools, techniques, processes, activities, standards, quality measuring tools, and team values. Current software development models are presented and briefly analysed. The need for a dedicated innovation oriented software development methodology is emphasized by highlighting shortcomings of current software development methodologies when tackling innovation. The ISDF methodology is presented in the context of developing an actual application. The ALHPA application is used as a case study for emphasizing the characteristics of the ISDF methodology. The development life cycle of the ISDF methodology includes research, planning, prototyping, design, development, testing, setup and maintenance. Artefacts generated by the ISDF methodology are presented. Quality is managed in the ISDF methodology by assessing compliance, usability, reliability, repeatability, availability and security. In order to properly asses each quality component a dedicated indicator is built. A template for interpreting each indicator is provided. Conclusions are formulated and new related research topics are submitted for debate.

  17. Evolution of aging assessment methodologies

    International Nuclear Information System (INIS)

    Under the influence of organizations like the IAEA and INPO the expectations of the regulator and plant operators alike are driving the evolution of aging assessment methodologies. The key result is that these assessments need to be executed more efficiently while supporting risk informed thinking within a living process. Some recent trends impacting aging assessments include new standards from the regulator requiring more frequent updates of aging assessments (RD-334), and broader component coverage driven by equipment reliability program demands (INPO AP-913). These trends point to the need to be able to do aging assessment more efficiently, and to manage the configuration. Some of the challenges include increasing efficiency while maintaining completeness and minimizing error, employing a systematic, well defined approach while maintaining the flexibility to apply the right level of effort to achieve desired results, and in particular, assuring that Aging Related Degradation Mechanisms (ARDMs) are sufficiently addressed. Meeting these needs creates a natural synergy with the Preventive Maintenance living program and therefore lends itself to a more integrated approach. To support this program, the SYSTMSTM software has been enhanced to accommodate for the various facets of an integrated program while meeting the needs described above. The systematic processes in SYSTMS are built with the vision of supporting risk-informed decision making as part of a larger risk-based functional tools suite. This paper intends to show how the utilities can benefit from the cost savings associated with increased assessment efficiency, and utilizing Candu Energy Inc.'s CANDU-specific knowledge-base and experience in aging assessment to get it right the first time.

    Full Text Available A finalidade deste texto é tecer uma reflexão metodológica sobre a recopilação e interpretação dos aspectos “não discursivos” da comunicação dos coletivos que estudamos. Desde um ponto de vista teórico-argumentativo é muito difícil negar a importância semiótica e sintática da corporalidade na construção social da realidade. Entretanto, quando analisamos as dinâmicas disciplinárias da antropologia, notamos que os significados corporais e sensíveis da vida coletiva ainda se consideram como um tipo de “dado” etnográfico marginal em relação às narrações discursivas facilitadas pelos sujeitos de estudo. Relataremos, então, como nossa etnografia sobre a imigração de brasileiros capoeiristas a Madri, dotou-se de uma perspectiva que tomava a corporalidade não apenas como um elemento reificado, mas como um espaço central de intercâmbios comunicativos: um lócus de encontro entre objetividade e subjetividade. Abstract: The aim of this paper is develop a methodological debate about the recollection and interpretation of the bodily aspects of the communication of the social groups studied by anthropologists. Since a theoretical point of view is almost impossible to deny the semiotic and syntactic importance of the corporality in building social realities. Nevertheless, the anthropological disciplinary dynamics still marginalizing the bodily and sensitive aspects of social life, considering then less important than the discursive narrative provided by the people the anthropologists study. This paper analyses how my ethnography about the Brazilian capoeiristas migration to Madrid (Spain, considered the corporality not only as a reality in itself, but also as a central space for communicative interexchange: a dimension of social life where objectivity meets subjectivity.

    Full Text Available A indústria de corantes desenvolve um importante papel na economia do mundo, visto que estes são utilizados em várias atividades fabris. Os corantes têxteis causam especial impacto no meio ambiente principalmente por serem de difícil degradação. Vários processos tem sido estudados a fim de que se consiga realizar um tratamento realmente efetivo em remoção de corantes de efluentes têxteis, entre eles os processos biológicos estão recebendo uma particular atenção por sua eficiência.O tratamento microbiológico de efluentes, especialmente por espécies fúngicas tem ganhado espaço, por estes organismos serem bastante versáteis, tratarem uma grande variedade de tipos de corantes e apresentarem diferentes mecanismos de remoção de cor. Portanto os fungos apresentam-se bastante atrativos e demonstram ser os organismos mais adequados em relação a tratamento de efluentes têxteis.

    Full Text Available Resumo: Nomear é uma ação. Toda ação requer instrumentos adequados para ser executada. A fala segue rigorosamente a natureza de fazer a fala, porque tudo tem sua forma natural de ser. Falar requer instrumentos, porque falar é uma ação. Os instrumentos da fala são os nomes, produzidos por quem de fato sabe como, por meio dos recursos naturais. Os nomes mudam, porque sempre se pode acrescentar ou tirar letras de sua forma. Assim foi que os nomes dos deuses são ditos de maneiras diferentes em lugares diferentes. Mas, todos os nomes são acordos ou convenções entre os falantes, em cada grupo os nomes variam de acordo com o que estiver convencionado. Portanto, os nomes variam de povo para povo, mas são sempre nomes certos, porque seguem a tradição natural de se nomear para aquele povo.

    Full Text Available This paper focuses on the current state of knowledge in the field of software development methodologies. It aims to set the stage for the formalization of a software development methodology dedicated to innovation orientated IT projects. The paper starts by depicting specific characteristics in software development project management. Managing software development projects involves techniques and skills that are proprietary to the IT industry. Also the software development project manager handles challenges and risks that are predominantly encountered in business and research areas that involve state of the art technology. Conventional software development stages are defined and briefly described. Development stages are the building blocks of any software development methodology so it is important to properly research this aspect. Current software development methodologies are presented. Development stages are defined for every showcased methodology. For each methodology a graphic representation is illustrated in order to better individualize its structure. Software development methodologies are compared by highlighting strengths and weaknesses from the stakeholder's point of view. Conclusions are formulated and a research direction aimed at formalizing a software development methodology dedicated to innovation orientated IT projects is enunciated.

  20. Screening radon risks: A methodology for policymakers

    International Nuclear Information System (INIS)

    This paper provides an easy-to-use screening methodology to estimate potential excess lifetime lung cancer risk resulting from indoor radon exposure. The methodology was developed under U.S. EPA Office of Policy, Planning, and Evaluation sponsorship of the agency's Integrated Environmental Management Projects (IEMP) and State/Regional Comparative Risk Projects. These projects help policymakers understand and use scientific data to develop environmental problem-solving strategies. This research presents the risk assessment methodology, discusses its basis, and identifies appropriate applications. The paper also identifies assumptions built into the methodology and qualitatively addresses methodological uncertainties, the direction in which these uncertainties could bias analyses, and their relative importance. The methodology draws from several sources, including risk assessment formulations developed by the U.S. EPA's Office of Radiation Programs, the EPA's Integrated Environmental Management Project (Denver), the International Commission on Radiological Protection, and the National Institute for Occupational Safety and Health. When constructed as a spreadsheet program, the methodology easily facilitates analyses and sensitivity studies (the paper includes several sensitivity study options). The methodology will be most helpful to those who need to make decisions concerning radon testing, public education, and exposure prevention and mitigation programs.26 references

  4. Risk management and expert system development methodology

    Science.gov (United States)

    Hull, Larry; Gilstrap, Lewey

    1991-01-01

    A risk-based expert-system development methodology has been developed to provide guidance to managers and technical personnel and to serve as a standard for developing expert systems. Expert-system development differs from conventional software development in that the information needed to prepare system requirements for expert systems is not known at the outset of a project and is obtained by knowledge engineering methods. The paper describes the expert-system life cycle, development methodology, and the approach taken in this methodology to manage and reduce the risks in expert system development. Also examined are the risks of using and of not using a methodology, the studies undertaken to validate the provisions of the expert system development methodology, and the results of these validation studies.

    This technical report was prepared for a preliminary safety analysis methodology of the 330MWt SMART (System-integrated Modular Advanced ReacTor) which has been developed by Korea Atomic Energy Research Institute (KAERI) and funded by the Ministry of Science and Technology (MOST) since July 1996. This preliminary safety analysis methodology has been used to identify an envelope for the safety of the SMART conceptual design. As the SMART design evolves, further validated final safety analysis methodology will be developed. Current licensing safety analysis methodology of the Westinghouse and KSNPP PWRs operating and under development in Korea as well as the Russian licensing safety analysis methodology for the integral reactors have been reviewed and compared to develop the preliminary SMART safety analysis methodology. SMART design characteristics and safety systems have been reviewed against licensing practices of the PWRs operating or KNGR (Korean Next Generation Reactor) under construction in Korea. Detailed safety analysis methodology has been developed for the potential SMART limiting events of main steam line break, main feedwater pipe break, loss of reactor coolant flow, CEA withdrawal, primary to secondary pipe break and the small break loss of coolant accident. SMART preliminary safety analysis methodology will be further developed and validated in parallel with the safety analysis codes as the SMART design further evolves. Validated safety analysis methodology will be submitted to MOST as a Topical Report for a review of the SMART licensing safety analysis methodology. Thus, it is recommended for the nuclear regulatory authority to establish regulatory guides and criteria for the integral reactor. 22 refs., 18 figs., 16 tabs. (Author)

    Full Text Available Este artigo busca mostrar a relação da juventude brasiliense com a política institucional, revelando o que está por trás da rejeição aos políticos profissionais e às instituições que ocupam. Em vez de estereotipar a postura crítica destes e destas jovens, sem antes analisar serenamente o contexto em que essa crítica surge, procurou-se mostrar o lugar de fala, a arena política em que surge essa crítica. Nessa arena, encontra-se uma democracia institucionalizada, com eleições estáveis, mas que não corresponde às expectativas que foram geradas com a sua implementação, junto com uma população bem informada e impactada por ações governamentais ou a ausência destas. Sem louvores ou reprovações, há que se perguntar se esta descrença da política institucional revela apenas uma desconexão de mundos ou a abertura de espaço para o surgimento de novas formas de organização política. O artigo trabalha com dados da PNAD 2005 e o Índice de Desenvolvimento Juvenil da UNESCO sobre a caracterização da juventude de Brasília e dados do TSE, sobre o alistamento eleitoral facultativo entre jovens.This article intends to analize the relationship between the city of Brasília´s youth and the institutional politics. We show what is behind the rejection to professional politicians and to the institutions they control. Instead of stereotipyze the critical behavior of the youth, we first analyze the context where this refusal takes place. We find an established democracy, with stable elections, but not corresponding to the expectations created during its implementation, added to a population that is well informed about the youth, it is necessary to ask if this lack of trust on institutional politics shows disconected worlds or a opened space to the emergence of new forms of political organization. This article is based on 2005 PNAD (National Research by Housing sample data and the Youth Development Index of UNESCO, to describe the

    Full Text Available The approval of the Brazilian law 11.769/2008 added to the Directives Law the compulsory musical teaching in Art in Elementary Education. Thus, interdisciplinary studies relating to Music and other subjects are frequent. Therefore, this study aims to unveil some contexts on which both Mathematics and Music relate to each other, developing a qualitative research based on historical and theoretical data. The objective is to present, from a didactic viewpoint, an interdisciplinary opinion and its contribution for the teaching-learning process. In view of the importance of the interdisciplinarity in the scholar schedule and the musical contribution for the learning process, an explanation of some didactic Math books which present approaches to Music Theory in Mathematical context was made. As a critical aspect, it is concluded that interdisciplinary studies, involving Music in Math classes are taken as positive strategies by renowned authors. A aprovação da Lei n° 11.769/2008 acrescentou à LDB a obrigatoriedade do ensino de Música na disciplina de Arte da Educação Básica. Com isso, trabalhos interdisciplinares, relacionando Música e as demais áreas do currículo são constantes. Nesse intuito, o presente artigo propõe-se a desvendar alguns dos contextos em que Matemática e Música se relacionam, desenvolvendo uma pesquisa de caráter qualitativo, a partir de dados históricos e teóricos. O objetivo é apresentar, do ponto de vista didático, um parecer interdisciplinar e as contribuições dessas disciplinas para o Ensino e aprendizagem de ambas. Amparando-nos na importância da Interdisciplinaridade no currículo atual e nas contribuições da Música para a aprendizagem, fizemos uma explanação de alguns livros didáticos de Matemática que apresentam abordagens de Teoria Musical no contexto matemático e discorremos sobre a interlocução entre estrutura musical e a matemática. Em uma atitude crítica, concluímos que o trabalho

    Full Text Available O artigo propõe uma leitura sistêmica do trabalho e dos processos de trabalho institucionais que intervêm nos esquemas de exclusão social. Centra-se especificamente no processo de trabalho institucional dentro de um hospital de saúde mental, propondo uma analogia com os das fábricas. O trabalho de enfermaria e sua história possibilitam, como modelo paradigmático, a releitura da história do trabalhador em geral, uma vez que nessa área eles atuam sobre os companheiros que se encontram em processo de degradação social. As dimensões abordadas a partir desse eixo são: a intervenção institucional e os processos de trabalho; o macroprocesso de exclusão/extinção social; e a epistemologia da co-produção de pesquisa para a análise dos processos sociais de trabalho. Nossa abordagem gnosiológica baseia-se na pesquisa co-produzida, a qual se constitui de dispositivos de intervenção transdisciplinares, entrevistas semi-estruturadas, histórias de vida focalizadas, observações de campo, relatos de co-pesquisadores trabalhadores e intertextos.The article proposes a systematic reading of work and the institutional work processes involved in patterns of social exclusion. It specifically centres on the institutional work process in a mental health hospital, proposing an analogy with the process of factory work. As a paradigmatic model, nursing work and its history enable a re-reading of the history of workers in general, since in this area workers are dealing first-hand with comrades who find themselves in a process of social degradation. The dimensions approached from this angle include: institutional intervention and work processes; the macro-processes of social exclusion/extinction; the epistemology and co-production of research for the analysis of the social processes of work. Our gnosological approach is based on co-produced research, formed by transdisciplinary intervention devices, semi-structured interviews, focused life

    Full Text Available Este artigo busca desafiar a visão amplamente disseminada de que o uso de formulações as if pelos economistas implica uma perspectiva metodológica instrumentalista (i.e., antirrealista. Baseado em uma análise do papel das proposições as if na teorização científica, argumenta-se que elas são também compatíveis com uma postura realista. Para efetuar a tarefa citada, discute-se o que são as formulações as if e identificam-se alguns dos seus usos realistas e instrumentalistas na prática efetiva de Economia e Biologia Evolucionária. Mais fundamentalmente, o presente trabalho sugere que o as if pode receber uma interpretação realista se consistir em uma contrapartida simplificada de uma explicação que descreve explicitamente processos evolucionários que produzem padrões de comportamento no mundo econômico real.This paper aims to challenge the widespread view that economists' usage of as if formulations implies an instrumentalist (i.e. anti-realist methodological perspective. Based on an account of the role played by as if propositions in scientific theorizing, it argues that they are also compatible with a realist posture. To undertake the foregoing task, it scrutinizes what as if formulations amount to and goes on to identify some realist and instrumentalist uses of them in the actual practice of economics and evolutionary biology. More fundamentally, the present work puts forth the idea that as if might receive a realist interpretation if it consists of a simplified counterpart of an explanation that explicitly describes evolutionary processes that bring about patterns of behavior in the real economic world.

Após definir a noção científica de Ecologia, procuram-se definir três conceitos-chave da Ecologia: o de potencial, que permite descrever, de forma inovadora, o modelo de relação entre sujeito e meio ambiente no âmbito da Somática; e os de diversidade e reciprocidade, a partir dos quais o artigo se revela como um convite e um programa para se pensar a respeito da integração da Somática ao paradigma ecológico científico. Para tal, recorre-se aos atores somáticos para transformar suas práticas de acordo com uma ética ambiental.

    Full Text Available A gastronomia molecular gera interesse e controvérsia desde que foi criada, em 1992, nos workshops de Erice, na Itália. Da curiosidade dos cientistas Nicholas Kurti e Hervé This, que desenvolveram a disciplina, à aplicação prática encontrada por chefs de todo o mundo, a gastronomia molecular é perseguida por parecer ser mais complicada do que realmente é: o estudo meticuloso dos alimentos. O objetivo desse artigo é descrever o seu surgimento e o que trouxe ao cenário contemporâneo enquanto tendência gastronômica. Para tanto, foi realizada uma revisão bibliográfica em livros e citações na imprensa estrangeira, o que permitiu descrever os motivos para que essa forma de cozinhar cause tanta polêmica.

No caso em foco, os alunos foram orientados a produzir textos argumentativos a partir de instruções disponibilizadas no Portal Educacional de uma instituição particular de ensino, que tem escolas conveniadas em vários pontos do Brasil. Os textos foram produzidos no computador e enviados para um avaliador na sede da instituição. O artigo discute inicialmente as orientações disponibilizadas on line para os alunos e professores. Em seguida, analisa um conjunto de 120 textos produzidos em duas escolas, uma situada em São Paulo - SP, outra em Fortaleza - CE. As orientações do Portal Educacional mostram a permanência de uma concepção tradicional de produção da dissertação escolar. Os textos produzidos on line pelos alunos das duas escolas escolhidas confirmam a mesma concepção tradicional. O caso estudado revela um descompasso entre a inovação tecnológica na escola e seu uso nas aulas de língua portuguesa. O computador e a internet dão uma aparência de modernidade a atividades tradicionais. Para finalizar, são indicadas alternativas para inovar a produção de textos e obter resultados mais interessantes com uso das tecnologias digitais.The present article discusses the use of the internet in activities related to text production in schools, focusing an activity developed by 8th grade students of the so-called 'fundamental school' in Brazil.

    2008-01-01

    The period histograms of eclipsing binaries generated with ASAS data cannot only be interpreted by orbital evolution. The eclipse probabilities, selection effects and space distributions in the solar neighborhood should be considered before any interpretations are made. Depending upon physical dimensions (total mass and period) of the progenitor stars and the efficiency of angular momentum loss (AML) mechanism, a newly formed W UMa type binary can be at any age up to several Gyr, and evolution in the contact stage is controlled not only by angular momentum and mass loss but also by mass transfer between the component stars. Thus, mean life of contact stages should be about 1.6 Gyr. A different time scale would cause inconsistencies.

    We present the NNDC-BNL methodology for estimating neutron cross section covariances in thermal, resolved resonance, unresolved resonance and fast neutron regions. The three key elements of the methodology are Atlas of Neutron Resonances, nuclear reaction code EMPIRE, and the Bayesian code implementing Kalman filter concept. The covariance data processing, visualization and distribution capabilities are integral components of the NNDC methodology. We illustrate its application on examples including relatively detailed evaluation of covariances for two individual nuclei and massive production of simple covariance estimates for 307 materials. Certain peculiarities regarding evaluation of covariances for resolved resonances and the consistency between resonance parameter uncertainties and thermal cross section uncertainties are also discussed.

    Full Text Available Featuring the contributions of semiotic discourse to the teaching of telejournalism, this article proposes the first stage of a project that seeks to highlight the syntax that governs the construction of the TV news, and in particular the report. It requires an examination of how its constituent units (off, sound, images, art, appearance of the reporter, etc. are combined to produce a "whole meaning" - a text. From the analysis of the report's structure, we verify the most recurrent uses and functions of each of these constituent units. In this article, the appearance of the reporter is the subject of a preliminary analysis of the "functioning" of the textual TV reporting. Based on a study of 100 scripts, we propose the description of seven syntactic features of the appearance of the reporter. Apresentando as contribuições que a semiótica discursiva pode dar ao ensino do telejornalismo, este artigo propõe-se a apresentar a primeira etapa de um projeto que busca evidenciar a sintaxe que preside à construção do telejornal e, em especial, da reportagem. A construção de uma sintaxe da reportagem requer o exame do modo como as suas unidades constitutivas (off, sonoras, imagens, arte, passagens, etc. se combinam para produzir um "todo de sentido" – um texto. Partindo da análise da roteirização das reportagens, buscamos verificar quais os usos e as funções recorrentes de cada uma dessas suas unidades constitutivas. Neste artigo, a passagem é objeto de um exercício preliminar de análise do "funcionamento" textual da reportagem. Baseados no estudo de 100 roteiros, propomos a descrição de sete funções sintáticas da passagem no texto-reportagem.

    Full Text Available The aim of this study was to compare some DNA extraction methodologies for Aegla longirostri. The protocols were based on the traditional phenol-chloroform DNA extraction methodology and using a commercial kit for DNA extraction. They differed in tissues used, the addition - or not - of beta-mercaptoethanol to the lysis buffer, times and methods for the animal's conservation (frozen, in ethanol or fresh. Individuals stored at -20°C for a long time supplied lower molecular weight DNA than those stored for a short time. The best yield for the specimens preserved in ethanol was obtained for 15 days storage in 95% ethanol. The kit resulted in a low quantity of high molecular weight DNA. The best protocol for DNA extraction from Aeglidae, and probably for other crustaceans should, therefore, utilize fresh specimens, with addition of beta-mercaptoethanol to the lysis buffer.Marcadores moleculares são ferramentas úteis para esclarecer dúvidas a respeito dos Aeglidae, único grupo de crustáceos Anomura de água doce. Essas técnicas dependem da obtenção de DNA de boa qualidade e sem contaminantes. O objetivo deste estudo foi comparar algumas metodologias de extração de DNA de Aegla longirostri. Quatorze protocolos foram analisados, baseados na metodologia tradicional de extração de DNA com fenol-clorofórmio, exceto o protocolo K no qual se utilizou um Kit. Os procedimentos diferiram quanto aos tecidos utilizados e a adição de beta-mercaptoetanol ao tampão de lise. Avaliaram-se também diferentes tempos e maneiras de conservação. Indivíduos congelados apresentaram maior degradação do material obtido conforme o tempo em que ficaram congelados. Para os indivíduos conservados em álcool, aqueles mantidos em etanol 95% forneceram material de melhor qualidade. A utilização do Mini Kit resultou em uma quantidade muito pequena de DNA de alto peso molecular. O melhor protocolo para extração de DNA de Aeglidae utilizou músculos e br

Não é nosso objetivo fornecer uma lista exaustiva de sintomas e síndromes para tratar do tema, já que buscamos discutir criticamente por que a semiologia das afasias ainda se baseia principalmente em perspectivas orgânicas na prática clínica e na pesquisa científica. Também discutimos as contribuições de Luria e de Jakobson para uma melhor compreensão de como a linguagem está comprometida nas afasias e como a Lingüística Moderna, sobretudo a Neurolingüística Discursiva, pode iluminar o debate. Analisamos alguns dados para ilustrar os pressupostos teóricos e metodológicos das referidas abordagens e discutimos ainda o peso excessivo que as classificações têm no contexto clínico.The article discusses the semiology of aphasias, which started being developed in the 19th century by Broca and Wernicke. We do not provide an exhaustive list of symptoms and syndromes to address the theme, since we aim to critically discuss why the semiology of aphasias is still based mainly on organic perspectives in clinical practice and scientific research. We also discuss the contributions of Luria and Jakobson to a better understanding of how language is affected in aphasias and how Modern Linguistics, in special the Discursive Neurolinguistics, may enlighten the debate. We analyze some data to illustrate the theoretical and methodological assumptions of the above mentioned approaches and also discuss the excessive strength that classifications have in the clinical context.

  18. Review and evaluation of paleohydrologic methodologies

    Foley, M.G.; Zimmerman, D.A.; Doesburg, J.M.; Thorne, P.D.

    1982-12-01

    A literature review was conducted to identify methodologies that could be used to interpret paleohydrologic environments. Paleohydrology is the study of past hydrologic systems or of the past behavior of an existing hydrologic system. The purpose of the review was to evaluate how well these methodologies could be applied to the siting of low-level radioactive waste facilities. The computer literature search queried five bibliographical data bases containing over five million citations of technical journals, books, conference papers, and reports. Two data-base searches (United States Geological Survey - USGS) and a manual search were also conducted. The methodologies were examined for data requirements and sensitivity limits. Paleohydrologic interpretations are uncertain because of the effects of time on hydrologic and geologic systems and because of the complexity of fluvial systems. Paleoflow determinations appear in many cases to be order-of-magnitude estimates. However, the methodologies identified in this report mitigate this uncertainty when used collectively as well as independently. That is, the data from individual methodologies can be compared or combined to corroborate hydrologic predictions. In this manner, paleohydrologic methodologies are viable tools to assist in evaluating the likely future hydrology of low-level radioactive waste sites.

  20. A design methodology for unattended monitoring systems

    International Nuclear Information System (INIS)

    The authors presented a high-level methodology for the design of unattended monitoring systems, focusing on a system to detect diversion of nuclear materials from a storage facility. The methodology is composed of seven, interrelated analyses: Facility Analysis, Vulnerability Analysis, Threat Assessment, Scenario Assessment, Design Analysis, Conceptual Design, and Performance Assessment. The design of the monitoring system is iteratively improved until it meets a set of pre-established performance criteria. The methodology presented here is based on other, well-established system analysis methodologies and hence they believe it can be adapted to other verification or compliance applications. In order to make this approach more generic, however, there needs to be more work on techniques for establishing evaluation criteria and associated performance metrics. They found that defining general-purpose evaluation criteria for verifying compliance with international agreements was a significant undertaking in itself. They finally focused on diversion of nuclear material in order to simplify the problem so that they could work out an overall approach for the design methodology. However, general guidelines for the development of evaluation criteria are critical for a general-purpose methodology. A poor choice in evaluation criteria could result in a monitoring system design that solves the wrong problem

  1. Grounded Theory as a General Research Methodology

    Directory of Open Access Journals (Sweden)

    Judith A. Holton, Ph.D.

    2008-06-01

    Full Text Available Since its inception over forty years ago, grounded theory has achieved canonical status in the research world (Locke, 2001, p.1. Qualitative researchers, in particular, have embraced grounded theory although often without sufficient scholarship in the methodology (Partington, 2000, p.93; 2002, p.136. The embrace renders many researchers unable to perceive grounded theory as a general methodology and an alternative to the dominant qualitative and quantitative research paradigms. The result is methodological confusion and an often unconscious remodelling of the original methodology (Glaser, 2003. Given the various interpretations and approaches that have been popularised under the rubric of grounded theory, this paper addresses the important distinction between grounded theory as a general methodology and its popularisation as a qualitative research method. The paper begins with a brief overview of grounded theory’s origins and its philosophical foundations then continues by addressing the basic distinction between abstract conceptualisation as employed in classic grounded theory and the conceptual description approach as adopted by many qualitative researchers. The paper continues with a brief overview of the criteria for judging the quality of classic grounded theory and concludes by detailing its methodological principles.

  2. A Indissociabilidade na Universidade. Fragmentos de uma experiência

    Directory of Open Access Journals (Sweden)

    Moura, Eliana Perez Gonçalves de

    2015-05-01

    Full Text Available This paper discusses the complex, tense and precarious connection between teaching, research and academic extension actions from the perspective of indissociability as a necessary condition for the academic training to break down the production of endogenous knowledge that is distant from social reality and disconnected from other types of knowledge. These writings are based on an experience developed by the authors, initially to meet demands for non-school educational practices in the academic extension setting, which advanced to solidarity economy. Since academic extension is a space of dialogue between university and community, as well as a place for the production of valid knowledge, we rely on its transgressive nature as an opportunity to join the sociability of ordinary men and women with their everyday knowledge, leading to the consequent and necessary problematization of what is taught and what is learned in higher education. Such experience has later become a Solidarity Economy Incubator and has produced effects on the teaching staff and the student body that were noticed both in teaching, research and academic extension practices and within the university itself as knowledge moving interdisciplinarity towards transdisciplinarity with the support of the solidarity economy movement, more specifically the theme of solidarity. Neste relato discute-se a complexa, tensa e precária articulação entre ações de ensino, pesquisa e extensão na perspectiva da indissociabilidade, enquanto condição necessária para uma formação acadêmica que rompa com a produção de saberes endógenos, distantes da realidade social e desconexos entre si. Os escritos partem de uma experiência, desenvolvida pelas autoras, inicialmente para atender demandas extensionistas de tipo práticas de educação não escolar e que avançam para a economia solidária. Enquanto espaço de diálogo entre a universidade e a comunidade, apostamos no caráter transgressor

    2008-08-01

    Full Text Available Partindo da constatação de que o recente interesse renovado dos cientistas sociais pelo fenômeno do terrorismo não se tem traduzido em um seu entendimento interdisciplinar maior, sugere-se que isso decorre do baixo nível de questionamento dos investigadores sobre o carácter político e ideológico dos seus estudos. Assumir que o terrorismo é uma construção social e política leva-nos a questionarmo-nos acerca das diferentes concepções de emancipação e regulação social que orientam a investigação desse fenômeno. Este artigo visa a explorar essa questão, problematizando a conceituação do terrorismo a partir da análise de quatro núcleos temáticos: as concepções políticas clássicas do terrorismo e o ponto de vista dos líderes revolucionários marxistas sobre esse fenômeno; as diversas concepções dos cientistas sociais e políticos sobre o novo terrorismo transnacional; a relação entre a democracia e o Direito na luta contra o terrorismo e a concepção do terrorismo como construção social. A análise conceitual realizada permitiu chegar a três questões que se sugere essenciais para uma Ciência Social crítica que vise a criar e a estimular alternativas de emancipação social. A primeira dessas questões diz respeito à impossibilidade de neutralidade científica e definição consensual do terrorismo; a segunda prende-se à análise do terrorismo a partir das vozes das suas vítimas; a terceira questão concerne à relação entre terrorismo, Direito e democracia.

    Full Text Available O objetivo do estudo é identificar os determinantes da folga organizacional em uma empresa com estrutura descentralizada, com ênfase no modo como os controllers das unidades de negócios afetam a folga. Foi realizada uma pesquisa descritiva com abordagem quantitativa, por meio de survey, utilizando o instrumento de pesquisa concebido por Indjejikian e Matëjka (2006, que se constitui de dois questionários, um para o gestor e outro para o controller de cada UN. A empresa objeto de estudo apresenta estrutura descentralizada com 45 UNs, das quais 32 responderam aos questionários. Os resultados da pesquisa indicam que as metas de desempenho, quando o crescimento das UNs é provocado pelo aumento das vendas e do market share, com sacrifício do retorno sobre o investimento no curto e médio prazos, são mais fáceis de alcançar e permitem maior folga organizacional do que em situações de UNs mais estáveis. Também indicam que a folga organizacional é maior em ambientes caracterizados por maior assimetria de informação entre a holding e os gestores das UNs, definidos pelo foco do controller da UN. Os resultados dos testes da relação entre as variáveis foco do controller da UN e folga organizacional evidenciam que os controllers das UNs priorizam o apoio à tomada de decisão na UN, em detrimento de suas responsabilidades com o sistema de controle gerencial corporativo. Quanto maior o tempo de atuação do controller na UN, maior é a sua dedicação às responsabilidades relacionadas à gestão da UN em detrimento do foco nas tarefas da holding. Conclui-se que a relação constatada nesta pesquisa entre o nível de folga organizacional e o foco dos controllers das UNs se coaduna com aquela enunciada no estudo de referência. De maneira geral, os resultados das análises estão alinhados com os da pesquisa de Indjejikian e Matëjka (2006, consideradas as limitações de comparabilidade em função das diferenças amostrais.

    Full Text Available Justificativa e objetivos. A toxoplasmose é uma doença infecciosa causada pelo parasita Toxoplasma gondiie apresenta elevadas taxas de transmissão vertical, podendo chegar a 65% no terceiro trimestre de gestação. O foco principal foi revisar o diagnóstico e manejo da toxoplasmose gestacional, destacando a importância do rastreio na gestação com solicitação de sorologias precocemente durante o pré-natal. Conteúdo. As principais formas de contrair a toxoplasmose gestacional são a ingestão de carnes mal cozidas e verduras mal lavadas e, ainda, o contato direto ou indireto com oocistos presentes nas fezes de gatos. O diagnóstico da toxoplasmose gestacional é feito através da pesquisa de anticorpos específicos das classes IgG e IgM contra Toxoplasma gondii em amostras de soro e o rastreamento é obrigatório durante o pré-natal. Apesar disso, essa doença apresenta alta prevalência no Brasil, com 60 mil novos casos ao ano, sendo considerado um grave problema de saúde pública.

    Full Text Available Teaching science to deaf-mute children has several limitations. In recent years, some techniques and resourceshave been presented to this public. However, many approaches still have to be done. The contact of thesestudents with science is made preferably by learning through the language of signals. The main objective of thepresent work is to encourage the use of the “tale and box” methodology as an efficient way to apply scientificknowledge for deaf-mute children. The tale was about Ema (deaf-mute children and her friends learning theimportance of Paleontology and fossils through the visit of a paleontologist to their school. The story was writtenin Portuguese Language, which was translated and adapted to the Brazilian Sign Language - LIBRAS. The storyhas been implemented in some classes of a deaf-mute care entity in Aracaju (Sergipe State, northeast Brazil.Such approach proved to be a valuable methodological tool on transmission of scientific information to deafmutechildren.

    Full Text Available Este artigo procura apresentar os conceitos de agenciamento e phylum maquínico, concebidos por Gilles Deleuze e Felix Guattari, para sublinhar o silício dentro do agenciamento contemporâneo homem-natureza. O silício (Si, matéria de destaque da microeletrônica, torna-se matéria expressiva de uma ética e de uma estética próprias. Com o objetivo de cartografar as forças que se colocam em ação em alguns agenciamentos homem-silício, busca criar uma imagem-pensamento tributária de uma estética do silício, que exprime um modo de existência. Neste trajeto, estão cartografadas algumas linhas de sustentação de uma sociedade de controle e outras linhas que agem em ruptura com a mesma. Com a arte, na idade da informatização planetária, vislumbram-se linhas orientadas a uma nova processualidade criativa e singularizante, capazes de promover mudanças nos posicionamentos do homem por uma vida portadora de certos valores estéticos.

    Full Text Available Pesquisas têm identificado semelhanças entre a heteroparentalidade e a homoparentalidade, tanto no que diz respeito às práticas parentais, como no que se relaciona com o desenvolvimento psicossocial das crianças e jovens. Contudo, comparativamente com o volume de investigação com mães lésbicas, os estudos com famílias homoparentais masculinas são ainda minoritários. O objetivo deste trabalho foi, assim, o de efetuar uma revisão crítica da literatura sobre homoparentalidade no masculino. Em primeiro lugar, refletimos acerca dos preconceitos particulares contra a parentalidade gay. Em segundo lugar, revimos os principais estudos com famílias homoparentais masculinas, publicados entre 1979 e 2011. Os resultados das referidas pesquisas foram organizados em torno de cinco temáticas: atitudes face à parentalidade, identidade sexual, relação com o contexto, competência parental e qualidade/dinâmica das relações familiares, e desenvolvimento psicossocial das crianças e jovens. Por último, destacámos algumas limitações e implicações para o futuro da investigação revista.

Esse estudo foi desenvolvido a partir da revisão de alguns autores a luz da abordagem ecológico-sistêmica. A questão da saída do adulto jovem da casa dos pais, momento crucial no desenvolvimento individual e familiar, vem sofrendo alterações pois observamos que atualmente está ocorrendo, em larga escala o fenômeno inverso, ou seja, a permanência do adulto jovem por mais tempo na casa dos pais. Observamos, hoje, uma variação na fase do ninho vazio, em que os pais costumavam ficar sozinhos no lar, para o “ninho cheio”, em que a família permanece toda residindo conjuntamente.

A partir desse entendimento, analiso um texto de natureza midiática, procurando evidenciar a leitura como um processo de produção de sentidos; essa concepção requer o reconhecimento de que o sujeito-leitor, o sujeito-autor e os sentidos são historicamente determinados. Requer também que se reconheça que ler é sempre um gesto de interpretação que se constitui no momento crítico de uma relação entre autor/texto/leitor.

  20. Basic methodological preconditions for high quality research

    Directory of Open Access Journals (Sweden)

    Ševkušić Slavica

    2006-01-01

    Full Text Available The paper considers basic methodological preconditions for the qualitative oriented research, in other words, the approaches which in the study of social phenomena rely on theoretical and methodological as well as epistemological premises of a new scientific paradigm. The paper draws special attention to the discussion of criteria of verifiability in qualitative research, which are significantly different from the criteria of positivist approaches. Interpretative research paradigms in social studies have a long history and numerous sources and the very concept of "interpretative shift" consists of a number of different research approaches unified under the name of qualitative methodology. The aim of the paper is not to prove that traditional and new paradigms and quantitative and qualitative research approaches based on them are incompatible in the process of discovering pedagogical reality. The intention is to demonstrate that the complexity of social phenomena requires a complex methodology meaning a complementary use of methods and techniques from both research approaches. The study of qualitative methodological approaches and their application in research, discovery and change of pedagogical reality are particularly important because they may provide new insights into pedagogical reality and a new view of old problems. .

    Assessing the risk of malevolent attacks against large-scale critical infrastructures requires modifications to existing methodologies that separately consider physical security and cyber security. This research has developed a risk assessment methodology that explicitly accounts for both physical and cyber security, while preserving the traditional security paradigm of detect, delay, and respond. This methodology also accounts for the condition that a facility may be able to recover from or mitigate the impact of a successful attack before serious consequences occur. The methodology uses evidence-based techniques (which are a generalization of probability theory) to evaluate the security posture of the cyber protection systems. Cyber threats are compared against cyber security posture using a category-based approach nested within a path-based analysis to determine the most vulnerable cyber attack path. The methodology summarizes the impact of a blended cyber/physical adversary attack in a conditional risk estimate where the consequence term is scaled by a ''willingness to pay'' avoidance approach.

    Probabilistic risk assessment (PRA) has become an increasingly important tool in the nuclear power industry, both for the Nuclear Regulatory Commission (NRC) and the operating utilities. The NRC recently published a final policy statement, SECY-95-126, encouraging the use of PRA in regulatory activities. Human reliability analysis (HRA), while a critical element of PRA, has limitations in the analysis of human actions in PRAs that have long been recognized as a constraint when using PRA. In fact, better integration of HRA into the PRA process has long been a NRC issue. Of particular concern, has been the omission of errors of commission - those errors that are associated with inappropriate interventions by operators with operating systems. To address these concerns, the NRC identified the need to develop an improved HRA method, so that human reliability can be better represented and integrated into PRA modeling and quantification.

The purpose of the Brookhaven National Laboratory (BNL) project, entitled 'Improved HRA Method Based on Operating Experience' is to develop a new method for HRA which is supported by the analysis of risk-significant operating experience. This approach will allow a more realistic assessment and representation of the human contribution to plant risk, and thereby increase the utility of PRA. The project's completed, ongoing, and future efforts fall into four phases: (1) Assessment phase (FY 92/93); (2) Analysis and Characterization phase (FY 93/94); (3) Development phase (FY 95/96); and (4) Implementation phase (FY 96/97 ongoing)

    This document describes a Software Development Methodology for High Consequence Systems. A High Consequence System is a system whose failure could lead to serious injury, loss of life, destruction of valuable resources, unauthorized use, damaged reputation or loss of credibility or compromise of protected information. This methodology can be scaled for use in projects of any size and complexity and does not prescribe any specific software engineering technology. Tasks are described that ensure software is developed in a controlled environment. The effort needed to complete the tasks will vary according to the size, complexity, and risks of the project. The emphasis of this methodology is on obtaining the desired attributes for each individual High Consequence System.

    Full Text Available According to Unconscious Thought Theory (UTT: Dijksterhuis and Nordgren, 2006, complex decisions are best made after a period of distraction assumed to elicit ``unconscious thought''. Over three studies, respectively offering a conceptual, an identical and a methodologically improved replication of Dijksterhuis et al. (2006, we reassessed UTT's predictions and dissected the decision task used to demonstrate these predictions. We failed to find any evidence for the benefits of unconscious decision-making. By contrast, we found some evidence that conscious deliberation can lead to better decisions. Further, we identified methodological weaknesses in the UTT decision task: (a attributes weighting was neglected although attributes were seen as different in importance; (b the material was not properly counterbalanced; and (c there was some confusion in the experimental instructions. We propose methodological improvements that address these concerns.
