Authors: Moraes Maria Erlândia , Silva Napiê Galvê Aráujo 
Published: July 2016

<p>Gestão Escolar nos dias atuais constitui-se um tema de grande relevância para a qualificação da ação educativa no âmbito da escola,<br />especialmente, das escolas públicas que historicamente têm sido cenário de diversos programas e projetos que adentram esse espaço na<br />tentativa de transformá-lo, e que muitas vezes, devido à descontinuidade das políticas educacionais públicas deixam em seus atores um misto de frustração e esperança de que dias melhores virão para a excelência do fazer pedagógico. Este trabalho objetiva tratar desse tema na vertente histórica e de qualidade da ação gerencial das escolas, há pouco extensiva ao gestor de sala de aula que tem papel primordial nessa evolução conceitual e no âmbito da gestão escolar por resultados. A metodologia utilizada para este estudo foi a consulta a documentos oficiais e resultados de aprendizagem obtidos pela EEM São Francisco da Cruz nos anos de 2012 a 2014, período de execução do Projeto Jovem de Futuro/Programa Ensino Médio Inovador, e observação direta da realidade associada à aplicação de questionários aos segmentos que compõem a escola: comunidade, pais, alunos, funcionários, professores e gestores. Deste estudo, pode-se chegar a conclusões importantes para o aperfeiçoamento e prática da gestão escolar, como o desenvolvimento de uma gestão democrática e participativa, com o exercício constante de relações de autoridade horizontais e responsabilização de todos na diversificação das parcerias existentes para atingir o foco da ação educativa: a aprendizagem dos alunos.</p>

Authors: Lima Mayara Barbosa Sindeaux , De Oliveira Vera Barros , Magalhães Celina Maria Colino 
Published: July 2016

<p>A brinquedoteca hospitalar é garantida pela Lei nº 11.104/05. Entretanto, verifica-se a existência de poucos parâmetros consolidados para avaliar esses espaços. O presente estudo objetivou verificar a autoavaliação dos técnicos das brinquedotecas hospitalares em Belém do Pará com base em indicadores de qualidade. Método: quatro hospitais que possuem este serviço participaram da pesquisa, dez técnicos foram entrevistados e responderam a Escala Autoavaliativa de Índices de Qualidade (EAIQ). Dentre os principais resultados encontrados estão: a) carência de registro documental acerca do histórico e funcionamento dos espaços; b) avaliação favorável da equipe, particularmente em três instituições; c) os participantes avaliaram que suas brinquedotecas promovem o brincar livre; d) o ambiente e o acervo lúdico obtiveram avaliações discrepantes entre as brinquedotecas; e) quanto às categorias de análise da EAIQ, considera-se que elas permitiram organizar as afirmativas que compõem o instrumento de forma congruente. Sugere-se, contudo, a inclusão de alguns aspectos. Concluiu-se que a análise qualitativa dos dados obtidos por meio da EAIQ mostrou-se apropriada para investigação de indicadores de qualidade. Além disso, o estudo permitiu traçar um perfil das brinquedotecas hospitalares com base na perspectiva de seus técnicos e ressaltou a pertinência de se discutir a elaboração de parâmetros de avaliação desses espaços.</p>
Educação Permanente em Saúde: a Problemática da Doação de Órgãos
Authors: De Aguiar Fernando , Moreira Janine 
Published: July 2016

<p>O presente artigo apresenta uma reflexão sobre educação permanente em saúde, a fim de pensá-la como instrumento capaz de transformar a<br />prática do profissional da saúde inserido no processo de doação de órgãos.Seu objetivo geral foi “identificar como se caracteriza a educação permanente dos profissionais de saúde dentro da política de doação de órgãos, segundo a perspectiva da educação libertadora”. Foi uma pesquisa exploratória, qualitativa e empírica, realizada com 14 profissionais de saúde que fizeram o Curso de Formação de Coordenadores Hospitalares de Transplantes, no ano de 2011 em Lages/SC, e cinco instrutores do curso. Foi estudada uma prática de educação permanente no contexto da doação e transplante de órgãos, tendo como referencial teórico o pensamento pedagógico de Paulo Freire.Os resultados apontam para a dificuldade em se estabelecerem práticas educativas no contexto de educação permanente em saúde de orientação conscientizadora, ainda que esteja presente o cuidado em se discutir os temas específicos em sua concretude. Levando-se em conta a questão específica da temática de doação e transplante de órgãos, que exige cuidados em sua abordagem, os resultados indicam que há um árduo trabalho a ser desenvolvido junto aos profissionais e familiares de doadores.</p>
Contribuições de Saussure: precursores, paralelos, sucessores e desdobramentos
Authors: Caetano Marcelo Moraes 
Published: July 2016

RESUMO:
Em relação às ideias e aos métodos de Saussure, apresentam-se, há muito, concordâncias e discordâncias. No entanto, em ambos os casos, houve desdobramentos de seus postulados. Ao propugnar pela ênfase sobre a unidade da língua, e não sobre sua heterogeneidade, Saussure sublinhou o método estruturalista, até hoje necessário para a elaboração e compreensão de uma gramática normativa. Os teóricos que o sucederam, com suas discussões prolíficas, também levaram adiante questões como o funcionalismo e o formalismo, e empreenderam não somente sólidas contribuições sobre o que caracteriza, efetivamente, a descrição linguística de um idioma (formalismo), mas, também, traçaram parâmetros sobre como essa descrição se relaciona com os seus usuários (funcionalismo).

Effects of Thread Depth in the Neck Area on Peri‐Implant Hard and Soft Tissues: An Animal Study
Authors: Sun Shan‐Pao , Lee Dong‐Won , Yun Jeong‐Ho , Park Kwang‐Ho , Park Kwang‐Bum , Moon Ik‐Sang 
Published: July 2016

Background: Implants with deep thread depth have been developed for the purpose of increasing total implant surface area. However, effects of implant thread depth remain controversial. The aim of this study is to examine effects of thread depth on peri‐implant tissues in terms of bone–implant contact (BIC), bone–implant volume (BIV), and hard and soft tissue dimensions using comprehensive analyses, including microcomputed tomography (micro‐CT).Methods: Five beagle dogs received experimental intramandibular implants 3 months after removal of their premolars and first molars (P2, P3, P4, and M1). Two different types of implants were installed in each animal: deep threaded (DT) and shallow threaded (ST). Resonance frequency testing was performed on the day of implantation as well as 4 and 8 weeks after implantation. Intraoral radiography, micro‐CT, and histomorphometry were used to evaluate peri‐implant tissues 4 and 8 weeks after implantation.Results: There were no significant differences in resonance frequency test results between the two groups. Although radiographic analysis showed no group differences, micro‐CT (P = 0.01) and histomorphometry (P = 0.003) revealed the DT group had significantly lower BIC values than the ST group at 4 weeks. However, by 8 weeks, BIC values of the two groups did not differ significantly. No significant differences in BIV or soft tissue height were observed between the two groups at either time point.Conclusion: DT implants showed no benefits over ST implants when inserted in dog mandibles.

Published: July 2016

Background: There is currently no consensus regarding microorganisms that may be considered true peri‐implant pathogens. Therefore, the aim of this systematic review is to determine the weight of evidence for microorganisms related to peri‐implantitis based on results of association studies.Methods: This review was performed following the Preferred Reporting Items for Systematic Reviews and MetaAnalyses (PRISMA). Two independent researchers searched PubMed/Medline, Embase, and Cochrane Library databases up to August 4, 2015, for studies comparing microbiologic outcomes of subgingival biofilm samples from healthy implants and implants with peri‐implantitis.Results: A total of 799 titles was identified and 11 studies were included in this review. All data were extracted using a predefined form. Microorganisms found in increased count/abundance/frequency in peri‐implantitis belonged to Bacteria domain and viruses, and included a total of six bacterial phyla, 17 bacterial genera, 23 bacterial species, and two genera of viruses. The main bacterial species associated with peri‐implantitis are recognized as periodontal pathogens.Conclusion: Results of this systematic review suggest moderate evidence supporting association of Porphyromonas gingivalis, Treponema denticola, and Tannerella forsythia and some evidence supporting association of Prevotella intermedia and Campylobacter rectus with the etiology of peri‐implantitis.
Grid-Sensitivity Analysis and Comparison Between Unstructured Perpendicular Bisector and Structured Tartan/Local-Grid-Refinement Grids for Hydraulically Fractured Horizontal Wells in Eagle Ford Formation With Complicated Natural Fractures
Authors: Sun Jianlei , Schechter David , Huang Chung-Kan 
Published: July 2016

Summary
In the context of modeling fractured horizontal wells, unstructured grids have been applied to generate simulation meshes for complex fracture networks. It is necessary to investigate how to choose an unstructured mesh to accurately simulate production performance. In this paper, a new unstructured gridding and discretization work flow is proposed to handle nonorthogonal and low-angle intersections of extensively clustered fractures with nonuniform apertures. The work flow is then validated with two models in terms of production behavior and central-processing-unit (CPU) performance: a synthetic model with one horizontal well and orthogonal intersected hydraulic fractures built by tartan grid, and a field-scale local-grid-refinement (LGR) model with three horizontal wells and irregular hydraulic fractures in a slightly dipping reservoir created by a commercial software plug-in.
Good-quality matches are obtained between unstructured and structured grids in both pressure and production behavior. Sensitivity analysis of the meshing parameters suggests that refinement in the vicinity of fractures has improved both early and late production of a well, whereas background density has a dominant effect on the late production. Background-grid type and orientation have less influence as long as they have the same grid density. Fewer cells can be achieved by increasing reservoir-background size and size-progression ratio, replacing unstructured-background grids with structured grids, and reducing the complexity of the fracture networks without loss of the accuracy, resulting in improved CPU performance.
This study applies unstructured grids to simulate multiple horizontal wells with complicated fracture networks, and provides detailed comparisons between unstructured and structured grids. Most importantly, it resolves the question regarding how to choose an appropriate mesh to yield both accurate results and high-quality CPU performance.
Proppant-Conveyor Automation System With Cascade Control in Hydraulic Fracturing
Authors: Chen Zheng , Naizer Brent , Kang Yongnam 
Published: July 2016

Summary
In this paper, a proppant-conveyor automation system is developed to automatically deliver proppant for hydraulic fracturing, which improves working conditions and reduces environmental pollution significantly. A cascade control is developed to reject disturbances and maintain the proppant level. The control consists of an inner-loop proportional-integral (PI) control for rejecting disturbances and an outer-loop PI control for maintaining the proppant level. A relay-feedback approach is adopted to tune the PI gains. Both simulation and hydraulic-fracturing-job testing results have validated reliability and practicality of the cascade control for the proppant-conveyor automation system.
Investigation of the Treatment Processes Effectiveness of the Surface Water at the Pilot Station and in a Technical Scale
Authors: Rak Adam 
Published: July 2016

The article focuses on both results of analysing the quality of the surface water taken from the reservoir and effectiveness of the water treatment process' technological examinations carried out both on a pilot station and in a technical scale. The research was carried out on the basis of the water taken from the reservoir named “Sosnowka” which is located at the Karkonosze mountain range bottom. There were 27 physical and chemical factors that underwent the examination.
The effectiveness of the water treatment process was assessed basing on such factors as follows colour reduction, turbidity and such indicators as: alkalinity, total hardness, oxidability and conductivity.
The 1st stage carried out throughout the water year included examining of the water treatment process' effectiveness in a pilot station in various technology systems by means of such unitary process as: sieving, pre-ozonation, pH correction, coagulation, filtration on anthracite and sand bed, final ozonation and sorption on active carbon.
The other stage concerned examination carried out in a technology system in a technical scale of a new water treatment plant. The good quality of the examined water at that time (pH = 6,9; colour = 15 mgPt/L-1) allowed for using a simple technology system with the use of such processes as: sieving, pre-ozonation, filtration on anthracite and sand bed, final ozonation and sorption on active carbon and final correction of the water quality with Na2CO3 and MgCl2.
The results aquired while carrying out laboratory technological examinations and those in technical scale allowed for establishing 3 optimal technology systems to be implemented while the water treatment plant operates.
Chromium (VI) adsorption onto activated sulfate lignin
Authors: Tazrouti Nassima , Amrani Moussa 
Published: July 2016

Activated lignin having surface area of 1023 m2.g-1 has been prepared from sulfate lignin that was treated by 30 % H2O2 and carbonized at 300 °C in order to test the chromium (VI) adsorption from aqueous solution. The influence of contact time, pH, initial concentration of adsorbent and adsorbate and temperature on the adsorption capacity were investigated. The maximum removal of Cr(VI) was found to be 92,36 % at pH=2 and contact time of 80 min. Optimal concentration of lignin and Cr(VI) were found to be 3.8 g.l-1 and 180 mg.l-1, respectively. The adsorption kinetics was tested pseudo-first-order and pseudo-second-order equation. The analytical data were fitted well in a pseudo-second-order equation and the rate of removal of chromium was found to speed up with increasing temperature. Activation energy for the adsorption process was found to be 18.19 Kj.mol-1. The Langmuir and Freundlich adsorption isotherm models were applied to describe the isotherm and isotherm constants for the adsorption of Cr (VI) on lignin. These constants and correlation coefficients of the isotherm models were calculated and compared. Results indicated that Cr (VI) uptake could be described by the Langmuir adsorption model. The maximum adsorption capacity (qm) of Cr (VI) on lignin was 75.75 mg.g-1 at temperature of 40°C. The dimensionless equilibrium parameter (RL) signified a favorable adsorption of Cr (VI) on lignin and was found between 0.0601 and 0.818 (0&lt;RL&lt;1). The thermodynamic parameters like ΔG°, ΔS° and ΔH° were calculated and it has been found that the reaction was spontaneous and endothermic in nature.
This study indicates that lignin has the potential to become an effective and economical adsorbent for removal Cr (VI) from the waste water.

Predictors of Reduced Frequency of Physical Activity 3 Months After Injury: Findings From the Prospective Outcomes of Injury Study
Authors: Harcombe Helen , Samaranayaka Ari , Derrett Sarah 
Published: July 2016

Abstract

Background
Physical inactivity is a risk factor for noncommunicable diseases. Incurring an injury has been identified as a barrier to physical activity. However, it is not known which factors, if any, are associated with reduced activity among general injury populations.

Objective
The 2 study objectives were: (1) to investigate changes in physical activity frequency from before an injury to 3 months after the injury and (2) to examine the association of preinjury, injury-related, and postinjury factors with reduced physical activity frequency in participants with a range of injury types.

Design
This was a cohort study.

Methods
Participants (N=2,856) who were 18 to 64 years of age were asked about preinjury demographic and health factors, injury-related factors, and postinjury factors. Data were collected through telephone interviewing (88%), a postal questionnaire (11%), and face-to-face interviewing (0.5%) 3 months after the injury.

Results
Of the 2,793 participants for whom complete physical activity data were available, 55% (n=1,536) had reduced physical activity 3 months after the injury event. Preinjury and injury-related factors associated with a greater risk of reduced physical activity included living with non-family members; a lower extremity dislocation, sprain, or strain; and an injury with greater anatomical severity. Postinjury factors associated with reduced physical activity included greater disability, pain or discomfort, poor general health, not having returned to work, and having a worse-than-expected recovery 3 months after the injury. A large proportion (61%) of this cohort with injuries was seen by physical therapists.

Limitations
Data collection was retrospective and based on participant recall.

Conclusions
A large proportion of participants had reduced physical activity 3 months after the injury. Knowledge about preinjury, injury-related, and postinjury characteristics associated with reduced physical activity may help health care professionals identify people at risk of not returning to their preinjury physical activity frequency.

OBJECTIVEGlioblastoma multiforme (GBM) is an aggressive brain cancer with median survival of less than 2 years with current treatment. Glioblastomas exhibit extensive intratumoral and interpatient heterogeneity, suggesting that successful therapies should produce broad anticancer activities. Therefore, the natural nontoxic pleiotropic agent, resveratrol, was studied for antitumorigenic effects against GBM.METHODSResveratrol's effects on cell proliferation, sphere-forming ability, and invasion were tested using multiple patient-derived GBM stem-like cell (GSC) lines and established U87 glioma cells, and changes in oncogenic AKT and tumor suppressive p53 were analyzed. Resveratrol was also tested in vivo against U87 glioma flank xenografts in mice by using multiple delivery methods, including direct tumor injection. Finally, resveratrol was delivered directly to brain tissue to determine toxicity and achievable drug concentrations in the brain parenchyma.RESULTSResveratrol significantly inhibited proliferation in U87 glioma and multiple patient-derived GSC lines, demonstrating similar inhibitory concentrations across these phenotypically heterogeneous lines. Resveratrol also inhibited the sphere-forming ability suggesting anti–stem cell effects. Additionally, resveratrol blocked U87 glioma and GSC invasion in an in vitro Matrigel Transwell assay at doses similar to those mediating antiproliferative effects. In U87 glioma cells and GSCs, resveratrol reduced AKT phosphorylation and induced p53 expression and activation that led to transcription of downstream p53 target genes. Resveratrol administration via oral gavage or ad libitum in the water supply significantly suppressed GBM xenograft growth; intratumoral or peritumoral resveratrol injection further suppressed growth and approximated tumor regression. Intracranial resveratrol injection resulted in 100-fold higher local drug concentration compared with intravenous delivery, and with no apparent toxicity.CONCLUSIONSResveratrol potently inhibited GBM and GSC growth and infiltration, acting partially via AKT deactivation and p53 induction, and suppressed glioblastoma growth in vivo. The ability of resveratrol to modulate AKT and p53, as well as reportedly many other antitumorigenic pathways, is attractive for therapy against a genetically heterogeneous tumor such as GBM. Although resveratrol exhibits low bioavailability when administered orally or intravenously, novel delivery methods such as direct injection (i.e., convection-enhanced delivery) could potentially be used to achieve and maintain therapeutic doses in the brain. Resveratrol's nontoxic nature and broad anti-GBM effects make it a compelling candidate to supplement current GBM therapies.
