Situações de bola parada no jogo de futebol: as sequências de jogo a partir dos livres no meio campo ofensivo

O estudo do futebol com recurso à análise do jogo tem servido para a compreensão da tendência evolutiva do jogo, para nortear o processo de treino e preparar a competição de forma eficiente. No presente estudo pretende-se detectar padrões comportamentais ocorridos a partir de livres ofensivos. A metodologia observacional, com recurso à análise sequencial com transições, prospectiva e retrospectiva, foi utilizada para a realização do estudo. A amostra foi constituída pelas sequências de jogo referentes aos livres observados em 7 jogos (quartos de final, meias finais e final) do Campeonato Europeu de Futebol 2008. Os resultados obtidos permitiram concluir que: a maioria das faltas sofridas ocorre durante o ataque posicional (57,5%), ataque rápido (35,3%) e nos primeiros 30 minutos de cada parte do jogo (1ªparte- 32,7%; 2ªparte- 24,7%). A análise sequencial prospectiva e retrospectiva permite afirmar ser significativa a probabilidade de: 1) o livre marcado directamente, no corredor central, activar: a) formação da barreira com 3 ou mais defesas, com pelo menos um atacante e uma defesa mista; b)trajectória da bola sem efeito e desmarcação para eventual recarga; c) remate com o pé finalizando em golo ou golo iminente; 2) o livre marcado indirectamente das zonas laterais activar: a) 3 ou mais atacantes na grande área e defesa mista; b) desmarcação do atacante que finaliza, com efeito da bola para o 1º e 2º poste, havendo superioridade e igualdade numérica atacante na zona alvo; c) remate com a cabeça e golo parcial; 3) situações de finalização com perigo ou perigo relativo serem activadas: a) pelo pé ou cabeça nas zonas próximas da baliza, em superioridade ou igualdade numérica atacante na área alvo; b) pela trajectória da bola ao 1º e 2º poste com desmarcação; 4) situações de finalização sem perigo serem activadas na ZLLB e ausência de desmarcação

Estado da arte da S.C.I.E. desde 1951 a 2008 e a sua aplicação como especialidade da engenharia

No âmbito da dissertação apresentada à Universidade da Madeira para cumprimento dos requisitos necessários à obtenção do grau de Mestre em Engenharia Civil, foi desenvolvida uma pesquisa na área da Segurança Contra Incêndio em Edifícios, abreviadamente designada por SCIE, desde 1951 a 2008 e a sua aplicação como especialidade da Engenharia, designadamente ao nível da fenomenologia da combustão, no que concerne à evolução histórica dos organismos, legislação, normas técnicas e factos históricos marcantes ao nível socioeconómico. Foi feita uma abordagem às normas europeias e à sua transcrição para as normas portuguesas devido ao factor político com a entrada de Portugal na C.E.E. em 1986. Neste sentido, este trabalho pretende dar a conhecer a evolução da SCIE em Portugal e exemplifica a sua aplicação como especialidade obrigatória para o licenciamento de qualquer edifício, independentemente da sua Utilização-Tipo à excepção dos estabelecimentos prisionais, instalações das forças armadas, espaços destinados ao armazenamento de explosivos e pirotecnia. O estudo de caso escolhido foi de um edifício de utilização mista da 4ª Categoria de Risco. Identificaram-se as diferenças entre a legislação anterior e o novo Diploma, a evolução histórica e as medidas a implementar no estudo de caso, apresentado no (anexo II), de acordo com o novo quadro legislativo.

O papel da administração e liderança do Gabinete do Ensino Superior da Região Autónoma da Madeira na valorização do ensino superior

O presente relatório evidencia duas partes do nosso trabalho; uma primeira sobre o estágio onde registamos todas as atividades desenvolvidas durante o decorrer do mesmo no Gabinete do Ensino Superior (GES) da Região Autónoma da Madeira (RAM) e na qual utilizamos a investigação-ação como metodologia recorrente, reflexiva e autocrítica. A segunda parte debruça-se sobre o estudo de investigação empírica, cujo objetivo era avaliar a importância de prosseguir os estudos para o nível de ensino superior. Neste sentido, realizámos o estágio no GES com o intuito de perceber o papel da administração e liderança deste Gabinete na valorização deste ensino, ganhando uma experiência prática de liderança educacional. Este relatório de estágio está inserido no âmbito do Mestrado em Administração Educacional (AE) da Universidade da Madeira (UMa). No decorrer do estágio, o Diretor do GES partilhou a sua liderança e exemplificou o seu quotidiano, fazendo perceber quais são os problemas mais frequentes com que tem de lidar, e qual a sua relação com os técnicos superiores, restante equipa e comunidade educativa. Através das técnicas de investigação, investigação-ação e observação utilizadas durante o estágio, percebemos o que é realmente liderar, consolidando assim toda a teoria aprendida com uma realidade prática, onde pudemos verificar que o líder “ideal” é o que combina a gestão com a liderança. Realizamos um estudo de investigação empírica de interesse para o GES onde se pretendeu saber quais são as motivações dos estudantes de 12º ano em prosseguirem os seus estudos para o ensino superior, para que desta forma fosse possível identificar o nível de motivação dos jovens, podendo assim tirar conclusões e encontrar possíveis soluções. Este estudo surgiu com base nas dúvidas e incertezas inerentes à nossa sociedade devido à conjuntura económica atual que questiona o prosseguimento ou não dos estudos para o ensino superior. A metodologia utilizada foi a qualitativa e a quantitativa, tratando-se de uma metodologia mista porque baseamo-nos na recolha de dados através de seis entrevistas realizadas a diretoras de turma de (9º e 12º ano) e 58 questionários implementados, bem como de pesquisas bibliográficas, documentais e legislativas. Concluímos que o Diretor do GES é um líder democrático pois toma a atitude de projetar e concretizar as atividades que têm de ser desenvolvidas, tendo sempre em atenção problemas e necessidades que surgem no grupo. Relativamente ao estudo de investigação empírica algumas das soluções encontradas para que a motivação de prosseguir os estudos continue e aumente passa por criar perspetivas de futuro mais positivas, haver mais oferta de cursos na nossa Universidade da Madeira e também mais emprego. Trabalhar esta motivação depende sobretudo das forças políticas, das famílias e dos professores. Assim, entendemos que os professores são líderes porque têm o papel de motivar os estudantes. Concluímos que a maioria dos estudantes do ensino secundário inquiridos estão motivados em ingressar no ensino superior, sobretudo pela motivação de obterem melhores condições de vida. Os que não se encontram motivados justificam que não o estão sobretudo pela atual condição do país. Todas as entrevistadas e a maioria dos inquiridos concordam que, e tal como a nossa revisão de literatura revela, estudar no ensino superior ainda compensa.

Bioenergia e exclusão regional: a não política nacional agroenergética e os girassóis do RN

This doctoral thesis presents an analysis of the production of bicarbonates and related regional development in Brazil. It is widely believed that one of Brazil s vocations lies in the agro-energy sector. However, current national agro-energy policies, together with the experience of Petrobras (the national oil company) in rural settlements in the state of Rio Grande do Norte, show that Brazil has fallen short of effectively including the North and Northeast regions of the country, let alone small-scale rural producers (residing in rural settlements or not), in the development process and related benefits from the country s participation in the current world energy grid. The methodology entails secondary research related to the theme, such as books, official documents, websites and statistical databases from diverse sources, in addition to an analysis of statements from interviews of Petrobras representatives and other important scientific, institutional and labor union authorities, in relation to agro-energy issues and the socio-economic participation of family-based agriculture in this process. Principal findings show a correlation between agro-energy and regional development, creating the potential for numerous opportunities and challenges. Findings demonstrate the possibility of reversing/reducing historically rooted indices of hunger and poverty that continue to devastate the North and Northeast regions. At the same time, the thesis points to a potentially catastrophic increase in regional disparities, should the present historic moment not be seized upon so as to include these regions. Classic examples of non-policy at the federal level are presented as evidence of the absence of a regionally focused agroenergy policy in the current government, reinforced by the experiences of Petrobras in the Rio Grande do Norte rural settlements. Finally, the thesis concludes that there is an urgent need to create a government-sponsored enterprise (with a structure similar to Petrobras) with the purpose of implementing a truly broad and inclusive development process for the bicarbonates production sector, while remaining attentive to Brazil s opportune and critical role in the world s current agro-energy scenario.

A Servidão Administrativa e o Estado Regulador: Compatibilidade com o Princípio Constitucional da Legalidade e a Limitação ao Direito Real de Propriedade

The economic changes occurred in the 90s, with the restructuring and privatization of various sectors of the economy have led to a redefinition of the State role, assuming a position of regulator and supervisor of public services in place to direct its role as straight intervenor. It is through the regulatory agencies, autarchies with special legal personality under public law, that the Regulator State will act. In this context, the first objective of this research is to analyze the legality of easements imposed by entities of the Direct Administration and Regulatory Agencies, whose execution is delegated to legal persons of private law, being those public service companies or mixed-economy societies. This examination in question the limits of servitude as a restrictive institute of property rights, observing the principles of function, supremacy of the public interests over the private ones, legality and the separation of powers. Defend the property rights like a fundamental right and your insurance as determining factor of economic development and social justice. Use the procedure in use will be the historiccomparative procedure, in order to demonstrate the legality of the public act as a maximum attempt to preserve the balance between the expansion of public services in various sectors of the economy, and the preservation of property rights, through regulation

Saúde Mental e enfermagem: em busca da integralidade na ESF

The present work shows an inquiry about the conceptions and practical work of the nursing professionals on the accompaniment of mental sick patients in the Family s Health Strategy, under the approach of the completeness in health. The justification of this research is given by bringing an special attention concerning the subjet to these professionals of health: the gradual abandonment of the traditional manicomial model leads to the insertion of mental patients in the community . The nursing professionals must be prepared to receive these patients in the basic net of health and contribute to help their adaptation and insertion in the social environment as citizen. In this context, considering the entire attention to the mental health, it is important to detach that the assistance to the patient must search his reinsertion in the community by providing programs that develops his sociability. This analytical study was developed using a qualitative approach and a thematic verbal history. Ten nurses of Nova Natal s Health of the Family Unit, of Felipe Camarão Mista s Unit and of Cidade da Esperança s Health Unit contributed for its development . The information was acquired through an instrument research that made possible the accomplishment of the interviews. These ones were set previously and counted on the assent of the participants. The interviews were recorded and analyzed in accordance with the pertinent literature concerning the subject. The aggregation of the information was then discussed. At this moment three thematic axles were defined dividing the categories of analysis. According to the results of the interviews, the practical procedure given to the patients with mental upheaval is resumed by the prescription of psicotroprics medicaments. It doesn t provide an accompaniment by the professionals of health, specifically, nurses, to the patients and their families. The lack of qualification and a multi-professional team emerged as one of the challenges for the implementation of practical procedures towards the patients with mental upheaval. Therefore, the results of this research show the necessity of transformations in the current scene of the mental health in the Family s Health Strategy. These changes can be reached by politics investments on the mental health area, not only financially but by providing human resources that should allow the professionals to exert the completeness procedures

Segurança do paciente no sistema de medicação: análise de enfermeiros de um hospital de ensino

This study aimed to identify and describe the factors related to Patient Safety in a medication system according to the nurses analysis in a teaching hospital from the photographic analysis method. This was a cross-sectional, descriptive study with mixed approach in a teaching hospital in Rio Grande do Norte. The population consisted of 42 nurses from inpatient units, of which 34 composed the study sample. As eligibility criteria, we defined nurses from public service and nurses who agreed to participate. Ethical determinations were observed, the study was submitted to the Ethics and Research of the University Hospital Onofre Lopes, obtaining the assent with ethical assessment certificate (CAAE 0098.0.051.294-11). For data collection, we used the photographic method (Photographic Analysis Technique) by Patricia Marck (Canada). It was developed in two phases: at first, we randomly captured photos from the medication system, resulting in 282 images; then we selected/processed the photographs, which were reduced to 10 images in Microsoft Excel 2010; in the second phase, the nurses answered the questionnaire divided into socio-professional profile and Digital Photography Scoring Tool (questions a and b ). For analysis of the question a , we used the content analysis technique, and for b , we used the Statistical Package for the Social Sciences 20.0 (temporary license). The socio-professional profile revealed the predominance of females; age group 34-43 years; professionals with specialization; 10-18 years of length of service; and nurses working exclusively in the hospital and who know the Patient Safety. The photographic analysis in relation to Patient Safety resulted in specific categories for each stage of the medication system. Regarding disposal, we identified Proper verification ; Improper verification ; Correct identification ; Disposal in single doses ; and Improper Environment , with predominance of that last category. As for storage: Proper storage ; Improper storage ; Risk of exchange/disappearance ; and Poor hygiene , with special reference to improper storage. In preparation: Risk of exchanging medication/patient ; Inappropriate physical space ; and Inadequate 9 preparation of controlled drugs , highlighting the first category. In drug administration: Lack of Personal Protective Equipment ; Use of Personal Protective Equipment ; Improper administration technique ; Proper administration technique ; Correct drug identification ; Incorrect drug identification ; and Peripheral venous access without identification . From the safety assessment of 10 photographs, by adapting the scores (1-10) to the Likert Scale, we identified three Totally Unsafe (Level 1), three Unsafe (Level 2), three Partially Safe (Level 3), one Safe (Level 4), and no photograph considered Totally Safe. This study identified the prevalence of unsafety in the medication system in the nurses opinion. We were also able to understand that, although nurses identify safety aspects, the most prevalent categories characterize an unsafe assessment. Nursing needs to reflect on its practice, identifying gaps in the medication system in order to achieve a proper and safe care

Práticas populares de cuidado à criança: o saber/fazer de cuidadoras

Popular practices correspond to the resources used by households, lay people and popular therapists, whose perception of knowledge is constructed in the everyday. In this context, the sick child can become vulnerable to be dependent on a family caregiver, who often decide to employ popular practices. Thus, the child care should be shared between carer and health professional. However, they know little about the resources that the family uses to detect a grievance in infant. Therefore, the present research aimed to analyse the use of popular practices by caregivers of children with zero to five years old. We conducted an exploratory and descriptive study with a qualitative approach, together with 15 caregivers of children who were treated at the Joint Unit Felipe Shrimp, located in Natal, Rio Grande do Norte, Brazil. To select the participants, they should be age and above 18 years; be caregivers of children up to five years of age; and reside in the area ascribed the Joint Unit Felipe Shrimp. The data collection took place between September and October 2013, through in depth interview. This step was preceded by the approval of the Health Department of the city of Natal; the direction of the Joint Unit Felipe Shrimp; as well as, the Committee on Ethics in Research from the Federal University of Rio Grande do Norte with Certificate of Presentation and Consideration Ethics, No 15467013.8.0000.5537. Furthermore, the interviewees formally authorized their participation in the research by signing the consent form. The data were treated according to the technique of content analysis in the form of thematic analysis according to Bardin. This process, four categories emerged: "Types of popular practices used in the care of the child"; "Source of information of popular practices"; "Results obtained with popular practices"; "Factors that hinder the adoption of common practices." The results showed the use of popular practices by caregivers in the case of illness to children such as the homemade preparations with medicinal plants and folk healers. The family environment was referenced as the main learning space and spread of popular practices, which are influenced by cultural relations present in this context. As to the results obtained with popular features, the caregivers said to be satisfactory, and this triggers a feeling of confidence and acceptability of such measures. It is concluded that the use of popular practices in child care persists in everyday most of the participants, despite the hegemony of allopathic therapy. The caregivers stated that such practices are effective and easy to obtain, being secured in context by popular culture. In addition, health professionals, especially nurses, were seldom mentioned by the caregivers as to the information concerning popular resources used by them, which suggests the weakness in dialogic process of negotiating practices between both of them

Infra-estrutura para avaliação e testes de protocolos sociais de comunicação em ambientes tridimencionais compartilhados

The advent of the Internet stimulated the appearance of several services. An example is the communication ones present in the users day-by-day. Services as chat and e-mail reach an increasing number of users. This fact is turning the Net a powerful communication medium. The following work explores the use of communication conventional services into the Net infrastructure. We introduce the concept of communication social protocols applied to a shared virtual environment. We argue that communication tools have to be adapted to the Internet potentialities. To do that, we approach some theories of the Communication area and its applicability in a virtual environment context. We define multi-agent architecture to support the offer of these services, as well as, a software and hardware platform to support the accomplishment of experiments using Mixed Reality. Finally, we present the obtained results, experiments and products

Uma abordagem comportamental para inserção de robôs em ambientes culturais

In this work, we propose methodologies and computer tools to insert robots in cultural environments. The basic idea is to have a robot in a real context (a cultural space) that can represent an user connected to the system through Internet (visitor avatar in the real space) and that the robot also have its representation in a Mixed Reality space (robot avatar in the virtual space). In this way, robot and avatar are not simply real and virtual objects. They play a more important role in the scenery, interfering in the process and taking decisions. In order to have this service running, we developed a module composed by a robot, communication tools and ways to provide integration of these with the virtual environment. As welI we implemented a set of behaviors with the purpose of controlling the robot in the real space. We studied available software and hardware tools for the robotics platform used in the experiments, as welI we developed test routines to determine their potentialities. Finally, we studied the behavior-based control model, we planned and implemented alI the necessary behaviors for the robot integration to the real and virtual cultural spaces. Several experiments were conducted, in order to validate the developed methodologies and tools

Inbreeding depression in castor bean (Ricinus communis L.) progenies

O objetivo do trabalho foi investigar a depressão endogâmica (DE) na mamoneira, espécie de reprodução sexuada mista. de uma população derivada da cultivar Guarani, amostraram-se 60 plantas-mãe. de cada uma foram obtidos três tipos de progênies: de autofecundação (AU), de cruzamentos obrigatórios (CR) e de polinização livre (PL). A produtividade de grãos das progênies for avaliada por meio de experimentos em blocos incompletos em dois locais. Houve forte interação de progênies x locais o que levou a obter estimativas dentro de cada local. Verificou-se ampla variação na depressão endogâmica, com médias de 6,7% e 13,4%, comparando-se as progênies AU com as PL. Verificou-se que a população tem alto potencial para selecionar linhagens promissoras. Foi baixa a freqüência de plantas-mãe gerando progênies com alta capacidade geral de combinação e baixa depressão endogâmica, simultaneamente. Seleção recorrente aumentará a ocorrência de genitoras associando essas duas propriedades, necessárias para obtenção de variedades sintéticas superiores.

Implementação paralela escalável e eficiente do algoritmo simplex padrão em arquitetura multicore

This work presents a scalable and efficient parallel implementation of the Standard Simplex algorithm in the multicore architecture to solve large scale linear programming problems. We present a general scheme explaining how each step of the standard Simplex algorithm was parallelized, indicating some important points of the parallel implementation. Performance analysis were conducted by comparing the sequential time using the Simplex tableau and the Simplex of the CPLEXR IBM. The experiments were executed on a shared memory machine with 24 cores. The scalability analysis was performed with problems of different dimensions, finding evidence that our parallel standard Simplex algorithm has a better parallel efficiency for problems with more variables than constraints. In comparison with CPLEXR , the proposed parallel algorithm achieved a efficiency of up to 16 times better

Síntese citrato-hidrotermal e caracterização eletroquímica de LSCF para aplicação como catodo em célula a combustível de temperatura intermediária

The lanthanum strontium cobalt iron oxide (La1-xSrxCo1-yFeyO3 LSCF) is the most commonly used material for application as cathode in Solid Oxide Fuel Cells (SOFCs), mainly due to their high mixed ionic electronic conductivity between 600 and 800ºC. In this study, LSCF powders with different compositions were synthesized via a combination between citrate and hydrothermal methods. As-prepared powders were calcined from 700 to 900°C and then characterized by X-ray fluorescence, X-ray diffraction, thermal analyses, particle size analyses, nitrogen adsorption (BET) and scanning electronic microscopy. Films of composition La0,6Sr0,4Co0,2Fe0,8O3 (LSCF6428), powders calcined at 900°C, were screen-printed on gadolinium doped ceria (CGO) substrates and sintered between 1150 and 1200°C. The effects of level of sintering on the microstructure and electrochemical performance of electrodes were evaluated by scanning electronic microscopy and impedance spectroscopy. Area specific resistance (ASR) exhibited strong relation with the microstructure of the electrodes. The best electrochemical performance (0.18 ohm.cm2 at 800°C) was obtained for the cathode sintered at 1200°C for 2 h. The electrochemical activity can be further improved through surface activation by impregnation with PrOx, in this case the electrode area specific resistance decreases to values as low as 0.12 ohm.cm2 (800°C), 0.17 ohm.cm2 (750°C) and 0.31 ohm.cm2 (700°C). The results indicate that the citrate-hydrothermal method is suitable for the attainment of LSCF particulates with potential application as cathode component in intermediate temperature solid oxide fuel cells (IT-SOFCs)
