Authors: Fraga Jorge F. , Prócel Luis Miguel , Trojman Lionel , Torres Francisco Javier 
Published: January 2016

En el presente estudio, las celdas unitarias del hafnio metálico (Hf), óxido de hafnio (HFO2), y nitruro de titanio (TiN), que son los componentes de una interfaz innovadora de tres capas: Hf/HFO2/TiN, que posee gran potencial para aplicaciones en nanoelectrónica, es descrita teóricamente mediante la aproximación de pseudopotenciales y ondas planas como se encuentra implementado en el Paquete de Simulación Ab Initio de Vienna (VASP).
Todos los cálculos se realizan usando la Aproximación del Gradiente Generalizado (GGA), con el funcional de Perdew-Burke-Ernzerhof (PBE). Como resultado del presente estudio, se propone un procedimiento sistemático para la simulación mecánico cuántica de cada sistema, resumido de la siguiente manera: (i) la construcción del modelo a partir de datos experimentales, (ii) determinación del valor óptimo de la energía de corte para las ondas planas, (iii) optimización del parámetro que determina el número de puntos κ en el espacio recíproco, y (iv) la optimización de la geometría de las posiciones atómicas y de los parámetros de celda. En el caso específico del HfO2, se aplica el método de correcciones coulómbicas localizadas (GGA+U) para calcular un bandgap de energía más exacto.

Root Coverage Procedure With Connective Tissue Graft Harvested From a Distal Wedge: A Case Report
Authors: Wang Chin‐Wei , Li Chia‐Cheng , Krawczyk Walter , Kim David M. 
Published: January 2016

Introduction: This case report illustrates the use of a connective tissue (CT) graft harvested from a distal wedge procedure for root coverage. The retromolar area could be an alternative donor site, especially when a distal wedge procedure is planned. This approach offers an alternative CT donor site for the treatment of a localized gingival recession (GR).Case Presentation: A healthy 22‐year‐old female patient presented with a localized Miller Class II GR defect on a mandibular incisor (tooth #25) caused by trauma from a lip piercing. Probing depths of 6 mm were also noted bilaterally over the distal aspect of the mandibular second molars. A root coverage procedure was performed, together with a distal wedge procedure for pseudopocket reduction. A CT graft harvested from a distal wedge was used for the root coverage. Complete root coverage with stable follow‐up was documented up to 2 years, 5 months. Tissue from a contralateral distal wedge was submitted for histologic evaluation. Histopathologic examination showed dense collagenous fibrous tissue with no inflammatory infiltrates.Conclusions: Localized GR can be treated with a CT graft harvested from a distal wedge without significant inflammation. The mandibular retromolar area may serve as an alternative viable donor site in selected cases.

Published: January 2016

The aim of this study was to evaluate the profile of dental students and its relationship to anxiety levels. The State-Trait Anxiety Inventory was applied to 207 first- to fifth-year undergraduates enrolled in the dentistry program at the School of Pharmacy, Dentistry and Nursing, Federal University of Ceará, Brazil. Participants were aged 17 to 29 years, and the maiority were women (57.5%). Students had a weekly workload of up to 40 hours and performed at least two complementary activities, in addition to their undergraduate training. Almost all students (95.7%) had attended private high schools and 80.6% lived with their parents or spouses. Regarding parental education, 59.4% of mothers and 55.6% of fathers had a higher education degree. Most students showed medium levels of anxiety according to measurements of state anxiety (53.1%) and trait anxiety (81.6%). It can be concluded that more than 50% of students in the Dentistry graduation course of the Federal University of Ceará showed an average level of anxiety, and that the excessive workload and enrichment activities necessary to obtain the undergraduate degree in Dentistry probably can be influencing the anxiety levels of students, however, more studies and statistical tests should be performed to identify the root causes in order to preserve the mental health of these future dentists.
Ocorrência de dor em bebês internados em unidade de terapia intensiva neonatal de maternidade terciária
Authors: Nazareth Caroline Diniz , Lavor Maria Francielze Holanda , Sousa Tânia Maria Araújo Santos 
Published: January 2016

Introdução: Por muitos anos, acreditou-se que os recém-nascidos (RNs) eram incapazes de sentir dor, devido ao pressuposto que seu sistema nervoso ainda não estaria completamente formado. Os RNs podem perceber a dor com mais intensidade do que as crianças e os adultos, devido aos seus mecanismos de controle inibitório imaturos, diminuindo capacidade de modular a experiência dolorosa. Objetivos: Identificar a ocorrência de dor em bebês internados e mensurar a utilização de analgesia farmacológica. Material e Métodos: Estudo transversal prospectivo, realizado nas Unidades de Terapia Intensiva Neonatal de um hospital terciário, no período de novembro de 2014 a fevereiro de 2015. Resultados: Dor foi identificada em 36% dos pacientes. Cinco (10%) pacientes receberam medidas farmacológicas de analgesia. Conclusão: Houve discrepância entre a frequência de dor encontrada e a de utilização de medidas para aliviá-la. Mostra-se necessária a implantação de um protocolo de avaliação e terapêutica de dor pela Instituição.
Staphylococcus aureus (MRSA and CA-MRSA strains) in South America: comparative review to emergence of strains in North America and worldwide
Authors: Farias Andre Leonardo Nogueira , Frota Cristiane Cunha 
Published: January 2016

Background: In the last few years, 3 different strains of MRSA have emerged: Community-associated Methicillin-resistant S. aureus (CA-MRSA), Hospital-associated (HA-MRSA), and Livestock-associated (LA-MRSA). The most common CA-MRSA strain is USA 300 lineage. In Brasil, this superbacteria is an important public health problem, once they are associated with severe infections (sepsis, shock and osteomyelitis), high mortality rates (including babies) and low response to usual treatments. Aim: To review attempts to compare CA-MRSA strains in South America and propose an interconnection with patterns of North America and worldwide strains. Methods: Non-systematic review. Findings: Epidemiological and Genotyping definitions were used to compare different strains in different continents. Thus, we could determine ST30+ as the most common lineage in the Brazil and South America, USA 300 lineage as the most common in North America and ST80+ as the most common in Europe. Conclusion: MRSA is a seriously public health problem in Brazil and worldwide. In few years scientist will need a better understand of bacteria-derived factors that participate in enhanced MRSA pathogenesis & host susceptibility. Also, scientists will need to improve tools for an early diagnosis and they will need to enhance preventative/therapeutic modalities. However, new challenges will keep emerging.

A obesidade é um sério problema de saúde mundial, responsável pelo aumento na incidência de diversas outras doenças, aumento da mortalidade total, e elevação dos custos com saúde. No Brasil, onde as doenças crônicas não comunicáveis dominam o ranking de mortalidade, mais da metade da população está acima do peso. Nesse contexto, o Ministério da Saúde estabeleceu a criação das Linhas de Cuidados direcionadas às doenças crônicas de maior impacto epidemiológico. As linhas de cuidado tem como objetivo coordenar os fluxos assistenciais que devem ser garantidos ao usuário, no sentido de atender às suas necessidades de saúde de maneira integral, e reduzir a fragmentação de serviços do Sistema Único de Saúde (SUS). Este documento propõe diretrizes clínicas para a organização de uma linha de cuidados em obesidade na rede pública de Fortaleza, onde o serviço especializado e multiprofissional será oferecido no Hospital Universitário Walter Cantídio.
Does Recent Academic Research Support Changes to Audit Reporting Standards?
Authors: Bédard Jean , Coram Paul , Espahbodi Reza , Mock Theodore J. 
Published: January 2016

SYNOPSIS
The Public Company Accounting Oversight Board (PCAOB), the International Auditing and Assurance Standards Board (IAASB), and the U.K. Financial Reporting Council (FRC) have proposed or approved standards that significantly change the independent auditor's report. These initiatives require the auditor to make additional disclosures intended to close the information gap; that is, the gap between the information users desire and the information available through the audited financial statements, other corporate disclosures, and the auditor's report. They are also intended to improve the relevancy of the auditor's report. We augment prior academic research by providing standard setters with an updated synthesis of relevant research. More importantly, we provide an assessment of whether the changes are likely to close the information gap, which is important to financial market participants and other stakeholders in the audit reporting process. Also, we identify areas where there seems to be a lack of sufficient research. These results are of interest to all stakeholders in the audit reporting process, as the changes to the auditor's report are fundamental. Additionally, our summaries of research on the auditor's report highlight where there is limited research or inconsistent results, which will help academics identify important opportunities for future research.
A Model to Update Accounting Curricula for Emerging Technologies
Authors: Coyne Joshua G. , Coyne Emily M. , Walker Kenton B. 
Published: January 2016

ABSTRACT
The prevailing model for accounting information systems (AIS) courses is decades old and needs to be modernized for cutting-edge technologies and demands for information services. New graduates in accounting require new perspectives and training to enter what is becoming an important subdiscipline in accounting that prepares accountants to serve effectively as data analysts, IT auditors, and participants in systems development. One hurdle preventing the adoption of these roles is a disconnect between AIS education and AIS practice. This article identifies relevant professional competencies and proposes some corresponding actions by the academy to combine accounting, management information systems, and computer technology.

<p class="Abstract">This study aimed to investigate the efficacy of shenfu injection for the protection of neonates with asphyxia. Eighty neonates with asphyxia were randomly divided into two groups, treatment group and control group (n=40). Both groups received interventions such as ventilation, oxygen, and circulation support. Treatment group was administrated with shenfu injection additionally. Serum levels of creatine kinase, alanine aminotransferase, aspartate aminotransferase, creatinine, and neuron-specific enolase were significantly lower but the oxygenation index was significantly higher in treatment group on day 7 and day 14. The neurobehavioral score was significantly higher in treatment group than in control group. On the 14<sup>th</sup> day, the survival rate of treatment group (77.5%) was higher than that of control group (55%). Shenfu injection could protect the function of the brain, heart, lung, liver and kidney by attenuating ischemia reperfusion after severe asphyxia resuscitation, improve neurobehavioral ability and increase the survival of neonates.</p><p> </p>
SEARCH FOR LOW-MASS OBJECTS IN THE GLOBULAR CLUSTER M4. I. DETECTION OF VARIABLE STARS

ABSTRACT
With every new discovery of an extrasolar planet, the absence of planets in globular clusters (GCs) becomes more and more conspicuous. Null detection of transiting hot Jupiters in GCs 47 Tuc, ω Cen, and NGC 6397 presents an important puzzle, raising questions about the role played by cluster metallicity and environment on formation and survival of planetary systems in densely populated stellar clusters. GCs were postulated to have many free-floating planets, for which microlensing (ML) is an established tool for detection. Dense environments, well-constrained distances and kinematics of lenses and sources, and photometry of thousands of stars simultaneously make GCs the ideal targets to search for ML. We present first results of a multisite, 69-night-long campaign to search for ML signatures of low-mass objects in the GC M4, which was chosen because of its proximity, location, and the actual existence of a planet. M4 was observed in R and I bands by two telescopes, 1 m T40 and 18-inch C18, of the Wise Observatory, Tel Aviv, Israel, from 2011 April to July. Observations on the 1 m telescope were carried out in service mode, gathering 12 to 48 20 s exposures per night for a total of 69 nights. C18 observations were done for about 4 hr a night for six nights in 2011 May. We employ a semiautomated pipeline to calibrate and reduce the images to the light curves that our group is developing for this purpose, which includes the differential photometry package DIAPL, written by Wozniak and modified by W. Pych. Several different diagnostics are employed for search of variability/transients. While no high-significance ML event was found in this observational run, we have detected more than 20 new variables and variable candidates in the M4 field, which we present here.
