A Osteotomia Segmentar de Maxila ou Osteotomia Le Fort I Segmentada é um procedimento que tem se tornado, cada vez mais comum, nas cirugias para as correções das deformidades dentofaciais, conhecidas como Cirurgias Ortognáticas. Este procedimento é muito bem indicado para a correção das discrepâncias maxilares, nos diferentes planos e num único tempo cirúrgico, otimizando assim, o tempo de tratamento a que o paciente é submetido. A estabilidade esquelética transversal e a oclusal dos pacientes, que são submetidos a este tipo de osteotomia, tem sido objeto de estudo na literatura , assim como também, os potenciais riscos e complicações inerentes a este procedimento como, a desvitalização dentária, fístula oro-nasal, perda dentária, necrose de algum segmento da maxila ou até mesmo, de toda a maxila. O objetivo deste trabalho é apresentar o caso clínico de um paciente submetido à osteotomia segmentar de maxila, e fazer uma revisão da literatura abrangendo os últimos 10 anos, com artigos que abordam a estabilidade deste tipo de procedimento, assim como também os potenciais riscos e complicações aos pacientes submetidos a este procedimento. Utilizando algumas palavras chave na base de dados eletrônica PUBMED, 12 artigos foram selecionados para este trabalho, no período de 2002 a 2012. A Osteotomia Segmentar de Maxila é um procedimento estável e seguro, com baixo índice de complicação, quando indicado corretamente e com os devidos cuidados no pré, trans e pós operatórios.

A method for calculating the globally optimal learning rate in on-line gradient-descent training of multilayer neural networks is presented. The method is based on a variational approach which maximizes the decrease in generalization error over a given time frame. We demonstrate the method by computing optimal learning rates in typical learning scenarios. The method can also be employed when different learning rates are allowed for different parameter vectors as well as to determine the relevance of related training algorithms based on modifications to the basic gradient descent rule.

Architecture and learning algorithm of self-learning spiking neural network in fuzzy clustering task are outlined. Fuzzy receptive neurons for pulse-position transformation of input data are considered. It is proposed to treat a spiking neural network in terms of classical automatic control theory apparatus based on the Laplace transform. It is shown that synapse functioning can be easily modeled by a second order damped response unit. Spiking neuron soma is presented as a threshold detection unit. Thus, the proposed fuzzy spiking neural network is an analog-digital nonlinear pulse-position dynamic system. It is demonstrated how fuzzy probabilistic and possibilistic clustering approaches can be implemented on the base of the presented spiking neural network.

Background: Food allergy affects quality of life in patients and parents and mothers report high levels of anxiety and stress. Cognitive Behaviour Therapy (CBT) may be helpful in reducing the psychological impact of food allergy. The aim of this study was to examine the appropriateness and effectiveness of CBT to improve psychological outcomes in parents of children with food allergy. Methods: Five parents (all mothers) from a local allergy clinic requested to have CBT; six mothers acted as controls and completed questionnaires only. CBT was individual and face-to face and lasted 12 weeks. All participants completed measures of anxiety and depression, worry, stress, general mental health, generic and food allergy specific quality of life at baseline and at 12 weeks. Results: Anxiety, depression and worry in the CBT group significantly reduced and overall mental health and QoL significantly improved from baseline to 12 weeks (all p < 0.05) in mothers in the CBT group; control group scores remained stable. Conclusions: CBT appears to be appropriate and effective in mothers of children with food allergy and a larger randomised control trial now needs to be conducted. Ways in which aspects of CBT can be incorporated into allergy clinic visits need investigation.

Stylization is a common method of ornamental plant use that imitates nature and evokes the scenery. This paper discloses a not yet proposed aspect of stylization, since the method offers the possibility of preserving the physiognomy of those habitats that seem to vanish due to future climate change. In addition, novelty of the method is founded also on that vulnerability of the Hungarian habitats has been examined by the researchers only from the botanical and ecological point of view so far and not in terms of its landscape design value. In Hungary, acidofrequent mixed forests appear to be highly sensitive to climate change according to ecological models. We are going to discuss the methodology of stylization of climate sensitive habitats and briefly refer to acidofrequent mixed forests as a case study. Those coniferous and deciduous tree species of the studied habitat that are water demanding are proposed to be substituted by drought tolerant ones with similar characteristics, and an optionally expandable list of these taxa is presented. Based on this the authors suggest experimental investigations of those of the proposed taxa for which the higher drought tolerance is based on observations only.

This paper presents an overview of literature on adult educators who are both queer and immigrant. Although very little scholarly writing exists, several scholars describe the experiences of queer immigrants as being anchored to systemic heteronormativity. Additionally, the experiences of immigrant adult educators suggest difficult encounters with racism and sexism.

Schools have evolved to be providers of education as well as suppliers of ancillary services to the population that they serve. This article examines one of these ancillary services, food service, in order to provide some awareness of the political aspects of the decision-making process in choosing whether or not to contract this service, as well as the pros and cons of the situation.

The adaptation to a new country is a complex and stressful process that is compounded when changes in status and identity have to be made. This exploratory study examined the adaptation of international company transferee spouses when they decide to follow the transferee on overseas assignments. Research to date indicates that the spouses’ dissatisfaction with life abroad is the leading cause of transferees breaking contract and prematurely returning home. The causes of this dissatisfaction are still not clear and this study sought greater clarification, particularly examining the experiences of male as well as female trailing spouses. The study, thus, takes gender as a main variable to consider. It explores how gendered expectations inherent in the structures of society inflect and inform the decisions, attitudes, and behaviors that affect the adaptations of trailing spouses living in a foreign habitus. The study is based on eight months of ethnographic research in two culturally different locations, Kuala Lumpur, Malaysia and Brussels, Belgium. Forty-two American international company transferee spouses were recruited (seven males and thirty-five females). The data analysis revolved around five main themes: (1) the comparison of male with female trailing spouses’ experiences, (2) the effect of location on spouses’ adaptation, (3) the communities that spouses integrate into, (4) variations in personal work and family histories, and (5) conditions of exit. The analysis engaged multiple theories regarding gender, sociological adaptation, and psychological adaptation. Results indicate that both socio-cultural and psychological factors affect adaptation and that gender matters very significantly, particularly along two axes: (1) gendered structures in our society create different reasons why males and females become trailing spouses, (2) the gendered social constructions of role expectations make the experience of being a trailing husband different from being a trailing wife. In addition spouses’ status as parents (or not) and their “readiness for change” were found to be important predictors of positive spousal adaptation. In contrast, significant ties with families in the home country and strong professional identity with career projections were important predictors of negative spousal adaptation.

This reconnaissance study was undertaken to determine whether the mass extinctions and faunal successions that mark the Cretaceous/Tertiary (K/T) boundary left a discernible molecular fossil record in the sediments of this period. Lipid signatures of sediments taken from above and below the K/T boundary were compared in core and outcrop samples taken from two locations: the U.S. east coast continental margin (western Atlantic Ocean, DSDP Site 605) and Stevns Klint, Denmark. Four calcareous sediments taken from above and below the K/T boundary in DSDP Hole 605, Section 605-66-1, revealed changing lipid signatures between above and below that are characterized by a large component of unresolved naphthenic hydrocarbons and a homologous series of n-alkanes ranging from Ci6 to C33. These lipid signatures are attributed to an influx of a terrestrial higher plant component and to bacterial reworking of the sediments under partially anoxic depositional and/or diagenetic conditions. The outcrop samples from Stevns Klint had extremely low concentrations of indigenous lipids. The fish clay at the K/T boundary contained traces of microbial hydrocarbons and fatty acids, whereas the carbonates above and below had only microbial fatty acids and additional terrestrial resin acids. The data from both sites indicate a perturbation in the deposition of lipid compound classes across the K/T boundary.

La relevancia del conocimiento como input del proceso productivo ha aumentado la complejidad de la contratación en el mercado de trabajo cualificado. Como consecuencia de ello, se ha generado un proceso de reflexión sobre la adecuación de la acreditación universitaria a las necesidades del mercado de trabajo. Académicos, gerentes y expertos en el mercado de trabajadores altamente cualificados han tenido parte en esta reflexión durante mucho tiempo. Este trabajo tiene como objetivo la identificación de las competencias profesionales con mayor relevancia en la empleabilidad de los graduados en Economía y Empresa. El análisis se basa en una investigación cualitativa que toma como fuentes de información las opiniones de los empleadores. La información para el estudio ha sido obtenida mediante entrevistas en profundidad y la realización de un grupo de discusión. En este proceso han participado empresarios, responsables del servicio de prácticas de la Universidad de Barcelona, expertos y responsables de empresa de colocación, representantes de organizaciones empresariales y profesores universitarios. La atención se centra en la percepción que los entrevistados tienen del requerimiento de conocimientos, habilidades y actitudes, en el grado en que los desarrollan y en los cambios que se necesitarían para lograr una mejor correspondencia entre las competencias adquiridas por los graduados y las requeridas por el mercado de trabajo. A partir de la clasificación de las competencias profesionales (proyecto Tuning), el estudio pone de relieve la importancia otorgada por los empleadores a de las competencias genéricas. No obstante, se observan diferencias valorativas según la tipología de empresas. Asimismo, se evidencian déficits en algunos aspectos relevantes, como la formación práctica y la capacidad de iniciativa, de análisis o de organización. Por último, de las opiniones recogidas también se constata la necesidad de aproximar la universidad al sistema productivo, al menos en el campo económico-empresarial.
