Abstract: the ever increasing use of network-integrated information systems is an information society's landmark. this universe of digital contents and media is prone to some threats that seriously compromise the security of the user-system-information relationship. information technology can present part of this problem's solution, but cannot solve it integrally. the information security policies must observe the balance between the human and technology issues about information security, in contrast with current policy models, extremely devoted to technological questions.

Abstract: Exp e-se o estado atual da disciplina Arquitetura da Informa o quanto a problemática terminológica da defini o do campo de estudo, apresentando-se argumentos para uma defini o de Arquitetura da Informa o de uma forma ampla na qual os usos correntes dessa express o sejam vistos como especializa es. Defende-se uma defini o com a utiliza o de um conjunto de propriedades mínimas cujas intera es levam a uma terminologia formal e cuja abstra o leva a uma defini o formal do conceito que emprega a linguagem de morfismos da Teoria das Categorias. Trata-se de um recorte de alguns dos resultados obtidos na tese de doutoramento de um dos autores, defendida em setembro de 2010. O contexto da pesquisa é exposto e alguns dos resultados obtidos s o delineados.
Raz?o e irracionalidade na representa??o do conhecimento
Carnielli, Walter A;Marques, Mamede Lima;
Trans/Form/A??o , 1991, DOI: 10.1590/S0101-31731991000100010
Abstract: how is it possible that beginning from the negation of rational thoughts (i.e. from the failure in the representation of knowledge, taking place through the presence of contradictory informations) one comes to produce knowledge? this problem, besides its intrinsic interest, acquires a great relevance when the representation of a knowledge is settled, for example, on data and automatic reasoning. many treatment ways have been tried, as in the case of the non-monotonic logics; logics that intend to formalize an idea of reasoning by default, etc. these attempts are incomplete and are subject to failure. a possible solution would be to formulate a logic of the irrational, which offers a model for reasoning permitting to support contradictions as well as to produce knowledge from such situations. an intuition underlying the foundation of such a logic consists of the da costa's paraconsistent logics presenting however, a different deduction theory and a whole distinct semantics, called here "the semantics of possible translations". the present proposing, following our argumentation, intends to enlight all this question, by a whole satisfactory logical point of view, being practically applicable and philosophically acceptable.

Couto, Christiane Marques do;Carvallo, Renata Mota Mamede;
Revista Brasileira de Otorrinolaringologia , 2009, DOI: 10.1590/S0034-72992009000100003
Abstract: characteristics of how external and middle ear resonance frequency can impact the capture of otoacoustic emissions. aim: to study the impact of external and middle ear resonance frequency in otoacoustic emissions. study design: prospective, clinical, series study. materials and methods: microphone-probe measurements were made in the external ear, together with multifrequency timpanometry distortion product transient otoacoustic emissions in 19 right and 20 left ears from male individuals and 23 right and 23 left ears from female individuals with 17 to 30 years of age. the 85 ears were audiologically normal. results: we did not observe statistically significant associations between the best otoacoustic emission best frequencies and the occluded external and middle ear resonance frequencies. conclusion: response levels for both transient and distortion product otoacoustic emissions are not influenced by the external and middle ear resonances alone.
Representa??o do corpo na rela??o consigo mesma após mastectomia
Ferreira, Maria de Lourdes da Silva Marques;Mamede, Marli Villela;
Revista Latino-Americana de Enfermagem , 2003, DOI: 10.1590/S0104-11692003000300006
Abstract: this research aimed to understand how the mastectomized woman represents her body in the relations with herself. social representations were used as a theoretical-methodological reference base. ten mastectomized women were interviewed at their homes on the seventh day after leaving the hospital and once a month during four postoperative months. the contents of the body representation to the self converged towards four meaning units: a) mutilated bodies, the perception of which was demonstrated in difference ways; b) feeling of impotence at different times in the postoperative period; c) pain and limitation, mainly at the beginning of recovery; d) care with the body. it could be understood that, for the women, the beginning of self-care took the form of an attitude that was developed in practices reflected and taught as a continuous process after the surgery. the perception of the body/constitution/mind/spirit relation permeated every moment of their existence. the results offer important elements for reflection in relation to the assistance to mastectomized women.
Representa o do corpo na rela o consigo mesma após mastectomia

Revista Latino-Americana de Enfermagem , 2003,
Abstract: Esta pesquisa objetivou compreender como a mulher mastectomizada representa o seu corpo nas rela es consigo mesma. O referencial teórico-metodológico foram as representa es sociais. Foram entrevistadas, no domicílio, dez mulheres mastectomizadas, no sétimo dia pós-alta e uma vez por mês, durante quatro meses de pós-operatório. Os conteúdos da representa o do corpo consigo mesma convergiram para quatro unidades de significa o: a) corpos mutilados, cuja percep o foi demonstrada de diferentes formas; b) sensa o de impotência em diversos momentos do período pós-operatório; c) dor e limita o, principalmente no início de sua recupera o; d) cuidado com o corpo. Foi possível entender que o princípio do cuidado de si para as mulheres tomou a forma de uma atitude, desenvolvida em práticas que foram refletidas e ensinadas como um processo contínuo após a cirurgia. A percep o da rela o de corpo/físico/mente/espírito permearam, todos os momentos, sua vivência. Os resultados oferecem importantes elementos para reflex o quanto à assistência às mulheres mastectomizadas.

Abstract: Este trabalho objetivou avaliar a composi o corporal e exigências nutricionais de cálcio e fósforo de cordeiro em sistema de pastejo na regi o semi-árida brasileira. Foram utilizados 32 cordeiros Santa Inês, castrados, com peso médio inicial de 15,8 ± 1,4 kg e idade entre três e quatro meses. Destes, oito foram abatidos no início do experimento representando a composi o corporal inicial (animais-referência) na metodologia do abate comparativo à medida que atingiam 15 kg. Os demais animais foram distribuídos aleatoriamente em três lotes com três níveis de suplementa o, sendo um para cada tratamento; quando o primeiro animal de cada lote atingia 30 kg, o respectivo lote era abatido. Os animais estavam em pastagens nativas enriquecidas com capim-buffel e suplementados com três diferentes níveis de mistura concentrada na dieta, correspondendo à suplementa o de 0,0; 1,0 e 1,5% de concentrado por dia. Os valores estimados de composi o corporal variaram de 17,11 a 14,91 g de Ca; 6,08 a 5,33 g de P por kg de peso de corpo vazio (PCV). As exigências líquidas de cordeiros de 15 a 30 kg para ganho de peso variaram de 10,8 a 9,4 mg, para Ca, e 3,89 a 3,76 mg, para P, por g de PV ganho. This work aimed to evaluate the body composition and the calcium and phosphorus nutritional requirements of Santa Inês lambs under rangeland conditions in the semi-arid region of Brazil. Thirty-twocastrated lambs between 3 to 4months old were used, with an initial mean body weight of 15.8 ± 1.4 kg. Of these, eight were slaughtered in the beginning of the experiment to provide the initial body composition (“Reference Animals” of the comparative slaughtermethod). The other animals were divided randomly in groups of three, as the lambs reached 15 kg. The three levels of food supplementation were randomly assigned to the lambs in each group (block). When the first animal in each group reached 30 kg, the whole group was slaughtered. The animals were kept in native rangeland enriched with buffelgrass (Cenchrus ciliaris L. cv. Biloela). Their diets were supplemented daily with three levels of concentrate mixture (0.0, 1.0 and 1.5% of their body weight). The estimated values of bodycomposition, in g kg-1 of empty body weight, ranged from 14.91 to 17.11 g for Ca, and from 5.33 to 6.08 g for P. The net requirements gain of 15-to-30-kg lambs, in g kg-1 gained in live body weight, ranged from 9.4 to 10.8 mg for Ca, and from 3.76 to 3.89 mg for P.

A bijection between noncrossing and nonnesting partitions of types A, B and C
Ricardo Mamede
Contributions to Discrete Mathematics , 2011,
Abstract: The total number of noncrossing partitions of type $Psi$ is the $n$th Catalan number $frac{1}{n+1}inom{2n}{n}$ when $Psi=A_{n-1}$, and the coefficient binomial $inom{2n}{n}$ when $Psi=B_n$ or $C_n$, and these numbers coincide with the correspondent number of nonnesting partitions. For type A, there are several bijective proofs of this equality; in particular, the intuitive map, which locally converts each crossing to a nesting, is one of them. In this paper we present a bijection between nonnesting and noncrossing partitions of types $A, B$ and $C$ that generalizes the type $A$ bijection that locally converts each crossing to a nesting.
