Un objet intelligent doit-il avoir l’air humain ? Etude de l’impact de l’anthropomorphisme d’un robot compagnon sur son acceptation
Authors: Goudey Alain , Bonnin Gaël
Published: January 2016

Résumé

Les produits intelligents devraient occuper une place centrale dans la vie des consommateurs au cours des prochaines années. Proches de l’humain par leur « intelligence », doivent-ils aussi ressembler physiquement à des humains ? L’objectif de cette recherche est de tester l’impact de l’anthropomorphisme anatomique d’un produit intelligent, le robot compagnon, sur son acceptation mesurée par l’utilité perçue, la facilité d’utilisation et l’intention d’utilisation. Les résultats de notre étude montrent que, contrairement aux principaux résultats des recherches antérieures, l’apparence humaine du robot compagnon ne favorise pas son acceptation par le consommateur. Nous montrons en revanche qu’un anthropomorphisme partiel favorise l’acceptation pour les personnes ayant une familiarité pratique avec une technologie proche (le smartphone) alors qu’elle la dégrade dans le cas contraire. Nos résultats mettent au jour les difficultés d’étendre les résultats des travaux menés en marketing sur l’impact de l’anthropomorphisme. Ils soulignent, par ailleurs, l’importance d’intégrer l’apparence dans les modèles d’acceptation. Ils témoignent également du rôle de l’expérience avec des produits proches du produit nouveau dans l’impact de l’apparence de ce dernier. Enfin, nous mettons en évidence le rôle du processus de catégorisation dans l’impact de l’apparence.

Key Points

Deletion of Hoxa genes reduces the engraftment potential of adult hematopoietic stem cells. Ectopic overexpression of Hoxa9 partially restores Hoxa−/− hematopoietic stem cell activity.
Fast and accurate branch lengths estimation for phylogenomic trees
Authors: Binet Manuel , Gascuel Olivier , Scornavacca Celine , P. Douzery Emmanuel J. , Pardi Fabio
Published: January 2016

Background

Branch lengths are an important attribute of phylogenetic trees, providing essential information for many studies in evolutionary biology. Yet, part of the current methodology to reconstruct a phylogeny from genomic information — namely supertree methods — focuses on the topology or structure of the phylogenetic tree, rather than the evolutionary divergences associated to it. Moreover, accurate methods to estimate branch lengths — typically based on probabilistic analysis of a concatenated alignment — are limited by large demands in memory and computing time, and may become impractical when the data sets are too large.

Results

Here, we present a novel phylogenomic distance-based method, named ERaBLE (Evolutionary Rates and Branch Length Estimation), to estimate the branch lengths of a given reference topology, and the relative evolutionary rates of the genes employed in the analysis. ERaBLE uses as input data a potentially very large collection of distance matrices, where each matrix is obtained from a different genomic region — either directly from its sequence alignment, or indirectly from a gene tree inferred from the alignment. Our experiments show that ERaBLE is very fast and fairly accurate when compared to other possible approaches for the same tasks. Specifically, it efficiently and accurately deals with large data sets, such as the OrthoMaM v8 database, composed of 6,953 exons from up to 40 mammals.

Conclusions

ERaBLE may be used as a complement to supertree methods — or it may provide an efficient alternative to maximum likelihood analysis of concatenated alignments — to estimate branch lengths from phylogenomic data sets.
Forming a joint dialogue among faith healers, traditional healers and formal health workers in mental health in a Kenyan setting: towards common grounds
Authors: Musyimi Christine W. , Mutiso Victoria N. , Nandoya Erick S. , Ndetei David M.
Published: January 2016

Background

Qualitative evidence on dialogue formation and collaboration is very scanty in Kenya. This study thus aimed at the formation of dialogue and establishment of collaboration among the informal (faith and traditional healers) and formal health workers (clinicians) in enhancing community–based mental health in rural Kenya.

Methods

Qualitative approach was used to identify barriers and solutions for dialogue formation by conducting nine Focus Group Discussions each consisting of 8–10 participants. Information on age, gender and role in health care setting as well as practitioners’ (henceforth used to mean informal (faith and traditional healers) and formal health workers) perceptions on dialogue was collected to evaluate dialogue formation. Qualitative and quantitative data analysis was performed using thematic content analysis and Statistical Package Social Sciences (SPSS) software respectively.

Results

We identified four dominant themes such as; (i) basic understanding about mental illnesses, (ii) interaction and treatment skills of the respondents to mentally ill persons, (iii) referral gaps and mistrust among the practitioners and (iv) dialogue formation among the practitioners. Although participants were conversant with the definition of mental illness and had interacted with a mentally ill person in their routine practice, they had basic information on the causes and types of mental illness. Traditional and faith healers felt demeaned by the clinicians who disregarded their mode of treatment stereotyping them as “dirty”. After various discussions, majority of practitioners showed interest in collaborating with each other and stated that they had joined the dialogue in order interact with people committed to improving the lives of patients.

Conclusion

Dialogue formation between the formal and the informal health workers is crucial in establishing trust and respect between both practitioners and in improving mental health care in Kenya. This approach could be scaled up among all the registered traditional and faith healers in Kenya.
Iterative algorithms for infinite accretive mappings and applications to p-Laplacian-like differential systems
Authors: Wei Li , Agarwal Ravi P
Published: January 2016

Some new iterative algorithms with errors for approximating common zero point of an infinite family of m-accretive mappings in a real Banach space are presented. A path convergence theorem and some new weak and strong convergence theorems are proved by means of some new techniques, which extend the corresponding works by some authors. As applications, an infinite p-Laplacian-like differential system is investigated, from which we construct an infinite family of m-accretive mappings and discuss the connections between the equilibrium solution of the differential systems and the zero point of the m-accretive mappings.
The Political Architecture of Dictatorship
Authors: Loveman Brian
Published: January 2016

This article describes the authoritarian institutions, political practices, and political culture of Chilean democracy before 1973. Although the military coup infringed constitutional procedures for government succession, the first measures taken by the military junta referenced existing constitutional, legislative, and administrative provisions as part of the effort to legitimize the coup. Examined in particular are pervasive use of constitutional regimes of exception (suspension or restriction of garantías constitucionales and expanded executive authority); application of extra-constitutional decree laws; delegation of legislative authority (facultades extraordinarias) to the executive branch; broad application of the penal code and legislation regulating the “internal security of the state” and “public order”; censorship and persecution of journalists, mass media, films, and private correspondence; surveillance and infiltration by secret police in unions, political parties, and social movements; use of the armed forces and national police (Carabineros) to control internal order, break strikes, and enforce arms control legislation; and jurisdiction of military courts over civilians for selected crimes defined in the Code of Military Justice.
Living the Chilean Revolution
Authors: Winn Peter
Published: January 2016

Industrial workers in Allende's Chile lived its revolutionary process most intensely. The Yarur cotton mill, Chile's largest, was the first big factory to be seized by its workers, nationalized by Allende, and incorporated into the social property area. It was also the first to introduce worker comanagement, an experiment in economic democracy that transformed workers into managers from the production sections on the factory floor to the elected worker councilors in the boardroom, and the unexpectedly powerful coordinating committee, composed of representatives from all of the work sections. “Ex-Yarur” workers also benefited from increased wages and benefits, internal promotions, and opportunities for social mobility and political advancement. Within the nationalized factory, there was also greater liberty, equality, and fraternity and increased worker dignity. Ex-Yarur was a success story of democratic socialism. But this success could not stop consumer shortages, programmed financial losses, or the counterrevolution outside the factory gates.
No + Wingka Word
Authors: Cárcamo-Huechante Luis E.
Published: January 2016

This article analyzes the poetry of Mapuche author Leonel Lienlaf as a form of resistance and agency from the graphic and sonic as well as the linguistic and literary reterritorialization of Mapudungun, the Mapuche language. The article focuses on poems from Lienlaf's first two books, both published in Chile: Se ha despertado el ave de mi corazón (The Bird of My Heart Has Awakened; 1989) and Pewma dungu / Palabras soñadas (Dreamed Words; 2003). As the article demonstrates, Lienlaf's poetry stages a ritualization of voices, sounds, and images that embody a Mapuche sense of language and territory. Moreover, it highlights the way Lienlaf's poems are records of auditory and sonic experiences that resist the “acoustic colonialism” imposed by the dominant state, corporate, and media actors in neoliberal, contemporary Chile.
Theatricalities of Dissent
Authors: del Campo Alicia
Published: January 2016

The 2011 student movement radically challenged the Chilean political process by exposing the hidden legacy of Augusto Pinochet's dictatorship and demanding a complete restructuring of its neoliberal reforms. The demonstrators contended that these so-called reforms transformed education into a for-profit venture that had gradually produced social segregation and unequal access to quality education. After more than seven months of protests, marches, school strikes, and flash mobs, the movement became the most powerful force for social change since the struggle against the dictatorship. A key element of their success was their effective use of social theatricalities to communicate protesters' demands and to rearticulate the meaning of urban space. This essay aims to demonstrate that these tactics grounded on a poetics of the body symbolically reappropriated the neoliberal city—segregated and consumption-driven—and transformed it momentarily into a lively and energized counter-neoliberal space, where a community marked by solidarity and the promotion of social change emerged.
The Declassified Pinochet File
Authors: Kornbluh Peter
Published: January 2016

This essay discusses the political process behind the Chile Declassification Project initiated by President Bill Clinton in 1999 and concluded during fall 2000. With the release of over 150,000 pages of sensitive records, Clinton's Chile Declassification Project became one of the largest discretionary executive branch releases of records on any country or foreign policy issue. The worldwide attention to Augusto Pinochet's detention in London put an international onus on the United States, whose classified government archives could provide pivotal evidence for Spain's efforts to finally bring the general to justice. Under increasing pressure from Congress, the families of the victims of the Pinochet regime, as well as human rights advocacy groups, Clinton authorized a major review and release of secret documents on Chile for the sake of historical transparency and support of Chile's truth and reconciliation process. In February 1999, the president authorized, and his administration initiated, the Chile Declassification Project.
Speaking, Thinking, Writing: Meditative Surgery and Intercorporeal Circulation in Henry Duke of Lancaster's Livre de Seyntz Medicines (1354)
Authors: Chenovick Clarissa
Published: January 2016

Henry of Lancaster's Livre de Seyntz Medicines is a vividly medicalized penitential narrative composed by a leading lay nobleman of fourteenth-century England. Grounded in the physiology of the medieval heart, Lancaster's understudied Livre demonstrates how medieval medical discourses could act as a vehicle for spiritual and psychophysiological change. Combining cognitive theories that view the heart as the tablet of memory with a physiology of the heart as a breathing organ that creates and circulates spirit, the Livre synthesizes medicine, natural philosophy, and theology into a program for the reform of memory, imagination, and will. As it articulates this process of reform through a series of meditative surgeries, the text adapts sophisticated Latinate clerical discourses for lay use and consciously uses physiological processes to make its program of spiritual self-reform available in physically and spiritually concrete ways to those who read or hear the text.
Stable atrogin-1 (Fbxo32) and MuRF1 (Trim63) gene expression is involved in the protective mechanism in soleus muscle of hibernating Daurian ground squirrels (Spermophilus dauricus)

Published: January 2016

Understanding the mechanisms that protect against or limit muscle atrophy in hibernators during prolonged inactivity has important implications for its treatment. We examined whether external factors influence the pathways regulating protein synthesis and degradation, leading to muscle atrophy prevention in Daurian ground squirrels (Spermophilus dauricus). We investigated the effects of 14-day hindlimb-unloading (HU) in different seasons and two-month hibernation on the soleus (SOL) muscle wet mass, muscle-to-body mass ratio, fiber cross sectional area (CSA), fiber distribution and muscle ultrastructure. We also measured changes in the protein expression and activation states of Akt, mTOR and FoxO1 and the mRNA expression of atrogin-1 and MuRF1. Compared with the control groups, autumn and winter HU significantly lowered SOL muscle wet mass and muscle-to-body mass ratio, decreased type I and II fiber CSA and induced ultrastructural anomalies. However, these measured indices were unchanged between Pre-hibernation and Hibernation groups. Furthermore, phosphorylation levels of Akt and mTOR significantly decreased, while the phosphorylation level of FoxO1 and mRNA expression of atrogin-1 and MuRF1 increased after HU. During hibernation, the phosphorylation levels of Akt and mTOR significantly decreased, but the phosphorylation level of FoxO1 and mRNA expression of atrogin-1 and MuRF1 remained unchanged. Overall, our findings suggest that disuse and seasonality may not be sufficient to initiate the innate protective mechanism that prevents SOL atrophy during prolonged periods of hibernation inactivity. The stable expression of atrogin-1 and MuRF1 may facilitate to prevent SOL atrophy via controlling ubiquitination of muscle proteins during hibernation.
Automorphisms with annihilator condition in prime rings
Authors: Bano Tarannum , Huang Shuliang , Rehman Nadeem ur
Published: January 2016

Let R be a prime ring, I a nonzero ideal of R, and a ∈ R. Suppose that σ is a nontrivial automorphism of R such that a{(σ(x ∘ y))n − (x ∘ y)m} = 0 or a{(σ([x,y]))n − ([x,y])m} = 0 for all x,y ∈ I, where n and m are fixed positive integers. We prove that if char(R) > n + 1 or char(R) = 0, then either a = 0 or R is commutative.
High rate of common bile duct stones and postoperative abscess following percutaneous cholecystostomy
Authors: Furtado R , Page P Le , Dunn G , Falk GL
Published: January 2016

Introduction

The short and long-term outcomes in patients managed with percutaneous cholecystostomy (PCY) at a single institution are described.

Methods

A retrospective study was conducted for patients treated between February 2000 and November 2012. Patient charts, imaging and biochemical data were reviewed. Patient demographics, presenting clinical features and treatment variables were noted. Outcome variables were length of admission, 30-day mortality, 30-day unplanned readmission, tube dislodgement, abscess formation, subsequent endoscopic retrograde cholangiography and surgery, complications after surgery and median overall survival.

Results

PCY was performed for 55 patients for acute cholecystitis where surgical risk was very high. The 30-day readmission rate was 20% (n=11), the 30-day mortality rate was 9% (n=5) and median survival was 59 months (95% confidence interval: 30–88 months). The median follow-up duration was 68 months. Tubes were dislodged in 15 patients (27%) and an abscess occurred after PCY in 5 patients (9%). Subsequent endoscopic common bile duct stone extraction was required in 20 patients (36%). Cholecystectomy was planned in 22 patients and an abscess occurred following the cholecystectomy in 5 (23%).

Conclusions

Although a PCY is lifesaving, significant morbidity can arise during recovery. This study demonstrates a high rate of choledocholithiasis (44%), tube dislodgement (27%) and postoperative abscess (23%) compared with previous reports.

Published: January 2016

Foreign body ingestion is a common presentation in clinical practice, seen predominantly in children. Most foreign bodies pass through the gastrointestinal tract without any additional morbidity. We present a case of gastric perforation secondary to the ingestion of a small plastic bag. We discuss the likely pathophysiological process underlying perforation secondary to plastic bag ingestion, which is most commonly associated with the concealment of narcotics.
Las Superbrands y social media en Portugal. Análisis de su estrategia de comunicación en Youtube
Authors: Costa Sánchez Carmen
Published: January 2016

Las Superbrands son un conjunto de marcas que reciben dicho distintivo por ser aquellas en las que los usuarios, en este caso portugueses, más confían. La presente investigación pretende conocer cómo esta serie de marcas “bien consideradas”, emplea las redes sociales y, específicamente, el uso que realizan de sus canales de Youtube. En un contexto en el que el consumo de vídeo online crece y Youtube se ha convertido en el segundo buscador por detrás de Google, resulta de interés plantearse cuáles son los contenidos con los que dichas marcas nutren sus propios canales. La investigación emplea una metodología cuantitativa (el análisis de contenido) y cualitativa (mediante la ilustración de casos) para responder a estos interrogantes. Los resultados muestran un uso conservador en cuanto al formato y a la finalidad de los mensajes.  Además, los datos de interactividad revelan el empleo unidireccional de la plataforma y detectan la ausencia de diálogo con los públicos. Se recomiendan dos líneas de contenidos para el éxito de la estrategia en Youtube: contenidos de uso práctico y mensajes novedosos que se diferencien del resto. Carece de sentido el empleo de Youtube como una pantalla secundaria respecto a la televisiva.

Authors: Mukdadi Afaf Abdullah , Batiha Abdul-Monim , Ortega Martin Jose Luis
Published: January 2016

Background: Some of the developmental problems facing students with difficulties in learning are those related to auditory perception which, in turn, can negatively affect the individual’s learning process.

Aim: Evaluating a training program prepared to develop the auditory discrimination skills of students who suffer from auditory discrimination problems.

Design: A quasi-experimental research design was used in this study. The study sample was divided into two equal groups: experimental and control.

Participants and setting: The population of the study consists of students with learning difficulties from the second, third and fourth grades, whose ages range between 7-9 years old. Also involved were those enrolled in the resource rooms affiliated to the Jordanian Ministry of Education in Irbid province, amounting to (120) boy and girl students for the school year 2013- 2014.

Results: The study showed that there was a significant difference in favor of the experimental group which indicated that the training program was effective. It helped the students with auditory discrimination problems to improve their reading skills. The results also showed a significant difference in favor of the students of older age in the experimental group. At the same time there were no significant differences in reading performance changes concerning gender.

In utero Exposure to β-2-Adrenergic Receptor Agonist Drugs and Risk for Autism Spectrum Disorders
Authors: Gidaya Nicole B. , Lee Brian K. , Burstyn Igor , Michael Yvonne , Newschaffer Craig J. , Mortensen Erik L.
Published: January 2016

OBJECTIVES:

The purpose of this study was to investigate associations between use of β-2-adrenergic receptor (B2AR) agonist drugs during pregnancy and risk for autism spectrum disorders (ASD).

METHODS:

A case-control study was conducted by using Denmark’s health and population registers. Among children born between 1997 and 2006, 5200 cases with ASD admission diagnoses and 52 000 controls without ASD were identified and individually matched on month and year of birth. Conditional logistic regression models were used to estimate odds ratios (OR) and confidence intervals (CI) for any B2AR agonist exposure during pregnancy, preconception, and by trimester.

RESULTS:

In total, 3.7% of cases and 2.9% of controls were exposed to B2ARs during pregnancy. Use of B2ARs during pregnancy was associated with increased risk of ASD, even after adjustment for maternal asthma and other covariates (OR: 1.3, 95% CI: 1.1–1.5). The elevated risk was observed with use of B2AR during preconception (OR: 1.3, 95% CI: 1.0–1.6), first trimester (OR: 1.3, 95% CI: 1.1–1.5), second trimester (OR: 1.5, 95% CI: 1.1–1.7), and the third trimester (OR: 1.4, 95% CI: 1.1–1.7). There was some evidence that longer B2AR within-pregnancy use was associated with the increased risk.

CONCLUSIONS:

B2AR agonist exposure during pregnancy may be associated with an increased risk for ASD. If the effect is real, any intervention must be balanced against benefits of indicated medication use by pregnant women.

Published: January 2016

Resumo O trabalho explorou a associação entre o gasto energético em atividades físicas e o escore de risco de Framingham entre idosos. Trata-se de um estudo seccional, incluindo 1.473 idosos. A variável dependente foi o nível de atividade física, estimado pela taxa de equivalentes metabólicos, em tercis. As variáveis exploratórias foram os componentes do escore de risco de Framingham e o próprio escore de risco de Framingham. A estimativa da força das associações foi baseada no cálculo do odds ratio e intervalos de confiança, utilizando a regressão logística ordinal. O maior nível de atividade física esteve associado a menores valores do escore de risco de Framingham, menor idade, menor proporção de diabetes e maiores valores médios de HDL. O maior gasto energético esteve ainda associado à menor chance de ser fumante entre os homens. Sugere-se que a adoção de um estilo de vida fisicamente ativo pode reduzir o risco coronariano, sendo o incentivo à prática da atividade física uma estratégia universal de combate às doenças crônicas não transmissíveis.

Resumo O objetivo desse estudo foi investigar a associação entre exposição a radiações eletromagnéticas não ionizantes da estação radiobase de telefonia celular e sintomas à saúde. Em um estudo transversal realizado em Salvador, Bahia, Brasil, entrevistaram-se 440 indivíduos. Queixas e diagnósticos psiquiátricos constituíram as variáveis dependentes e a distância do domicílio para estação radiobase foi considerada a variável independente principal. Realizou-se análise de regressão logística hierarquizada para avaliação de confundimento e efeito. Observou-se associação entre sintomas psiquiátricos e residir próximo à estação radiobase e formas de uso do telefone celular (sinal de cobertura fraco, perto do corpo, dois ou mais chips e nunca desligar o celular quando dorme) e com uso de outros eletroeletrônicos. Concluiu-se que a exposição à radiação eletromagnética não ionizante de telefonia celular e a outros eletroeletrônicos foi associada aos sintomas psiquiátricos independente do sexo, escolaridade e tabagismo. Recomenda-se a adoção de medidas precaucionárias no sentido de se reduzir este tipo de exposição.
Estimativas de cobertura de óbitos e da mortalidade adulta em Moçambique a partir de dados censitários
Authors: Alberto Serafim Adriano , Queiroz Bernardo Lanza
Published: January 2016

Resumo Os censos demográficos de Moçambique de 1997 e 2007 incluíram, em seu questionário, a pergunta sobre óbitos ocorridos no domicílio nos últimos 12 meses. O objetivo do artigo é fazer uma avaliação da qualidade da informação de mortalidade do censo para o país e suas três grandes regiões. Mais especificamente, com base em métodos demográficos formais, busca-se avaliar a qualidade da informação em termos de grau de cobertura da enumeração de óbitos e da estrutura de mortalidade, sumarizada pela probabilidade de morte entre 15 e 60 anos de idade. Em 2007, o censo enumerou entre 65 e 90% dos óbitos ocorridos em Moçambique, indicando que estimativas de mortalidade usando métodos diretos subestimam a mortalidade no país. O trabalho mostrou que há uma avanço na qualidade da enumeração da mortalidade no país e que na ausência de registros vitais de qualidade, os censos demográficos podem ser uma boa fonte de informação de mortalidade para os países em desenvolvimento.

Each group was subdivided in 3 subgroups according with the healing phases, 3, 7 and 21 days of consecutive therapeutic sessions. The ultrasound therapy began 24 hours after the termination of the surgical act, at the dorsal region, applying frequency of 3 MHz and intensities 0.5 W/cm2 and 2.0 W/cm2 during 5 minutes under sliding technique. Later, the animals were sacrificed according to the healing phases for removal of incisional area and histological analyses. Conclusions : The results allowed conclude that the continuous mode of therapeutic ultrasound in the intensities 0.5 W/cm2 and 2.0 W/cm2promoted stimulus to formation of collagens types I and III in the lesion area for first intention.
Effect of Fluoride Varnish Combined with Er:YAG Laser on the Permeability of Eroded Dentin: An In Situ Study
Authors: Nemezio Mariana Alencar , Carvalho Sandra Chiga , Scatolin Renata Siqueira , Colucci Vivian , Galo Rodrigo , Corona Silmara Aparecida Milori
Published: January 2016

This study evaluated the combined effect of fluoride varnish and Er:YAG laser on the permeability of eroded bovine root dentin. After initial erosive challenge followed by a remineralization period, the specimens were divided in two groups according to the treatment - fluoride varnish and non-fluoride varnish - and were subdivided according to the irradiation protocol: Er:YAG laser (100 mJ, 3 Hz, 12.8 J/cm2per pulse, non-contact and defocus mode) and non-irradiated. After a lead-in period, 7 volunteers wore a palatal device containing 4 specimens that were subjected to erosive challenges. At the first experimental phase, 4 volunteers used specimens treated with fluoride varnish and fluoride varnish+Er:YAG laser and 3 volunteers used specimens treated with non-fluoride varnish and non-fluoride varnish+Er:YAG laser. After a washout period, volunteers were crossed to treatments, characterizing a 2x2 crossover experiment. At the end of the experimental phase, the quantitative response variable was obtained by permeability analysis and the qualitative response by scanning electron microscopy (SEM). Two-way ANOVA and Tukey-Kramer's test revealed that specimens treated with fluoride varnish+Er:YAG laser showed the lowest permeability and a significant difference was found between this group and the others. When varnish (fluoride/non-fluoride) was applied in the absence of Er:YAG laser, higher permeability was found when compared to the laser-treated groups. SEM evaluations showed partially or completely obliterated dentinal tubules when specimens were treated with fluoride varnish+Er:YAG laser. It may be concluded that Er:YAG laser was able to control the permeability of eroded root dentin and the combination with fluoride varnish increased laser action.

Published: January 2016

This retrospective study evaluated the clinical outcome of 139 teeth restored with carbon fiber posts after 3 years of placement, considering the amount of remaining dentin as the main variable. Eighty-one patients received the fiber posts within a period of 16 months and were recalled after 3 years. The tooth type, amount of remaining dentin, and prosthetic crown material were evaluated. No loss of post or core retention was detected after 3 years of follow up. During the observed time, root or post fracture and secondary caries were not recorded. Only one failure concerning endodontic treatment was detected. The amount of remaining dentin was not an important characteristic in the restorative failure of endodontically treated teeth restored with carbon fiber posts within 3 years.

Published: January 2016

Tutankhamun was a Pharaoh of the 18th Dynasty (New Kingdom) in ancient Egypt. Medical and radiological investigations of his skull revealed details about the jaw and teeth status of the mummy. Regarding the jaw relation, a maxillary prognathism, a mandibular retrognathism and micrognathism have been discussed previously. A cephalometric analysis was performed using a lateral skull X-ray and a review of the literature regarding King Tutankhamun´s mummy. The results imply diagnosis of mandibular retrognathism. Furthermore, third molar retention and an incomplete, single cleft palate are present.

Published: January 2016

This cross-sectional study aimed to assess the influence of race/ethnicity on Brazilian children' oral health-related quality of life (OHRQoL). A multistage random sampling selected a representative sample of 1,134 twelve-years-old children from public schools of Santa Maria, a city in Southern Brazil. Participants were examined by 4 calibrated clinicians (minimum Kappa-value for inter-examiner agreement of 0.8) and the Brazilian short version of the Child Perceptions Questionnaire (CPQ11-14) was administered. The children's parents or guardians answered questions regarding their demographics and socioeconomic status. Associations were analyzed using multilevel Poisson regression models. Children from racial/ethnic minority groups had poorer OHRQoL. The mean CPQ11-14 score was 1.08 times higher for non-white children than their white counterparts' score. "Social" and "Emotional well-being" were the most affected domains for non-white children, with significantly higher mean scores as compared to white children (RR 1.19, 95% CI, 1.07-1.33; and RR 1.14; 95% CI 1.04-1.24). This association remained significant even after adjusting for individual and contextual covariates. OHRQoL disparities are prevalent among children from racial/ethnic minority groups. Non-white children have lower OHRQoL compared to white children.

Este trabalho teve como objetivo verificar a validade preditiva do IRDI, a partir de sua relação com dois instrumentos: o Autoquestionnaire Qualité de Vie Enfant Imagé (AUQUEI) e o Child Health Questionnaire (CHQ), ambos já validados no Brasil e aplicados aos seis anos de vida. A amostra foi composta por 46 crianças de três centros de saúde de São Paulo. Os resultados indicaram que o IRDI não se mostrou sensível à avaliação de qualidade de vida obtida com o uso do AUQUEI. No entanto, a associação estatisticamente significante encontrada entre resultados obtidos no IRDI e no CHQ mostrou maior capacidade do IRDI para predizer qualidade de vida relacionada ao índice psicossocial do que ao índice físico do mesmo instrumento.
A contribuição de Michel Henry para a prática clínica na atualidade
Authors: Safra Gilberto
Published: January 2016

Resumo: Este trabalho busca discutir os quadros psicopatológicos contemporâneos, decorrentes de um contexto sociocultural, no qual encontramos a vida humana organizada segundo os princípios fundamentais que caracterizaram a modernidade e a pós-modernidade. O mal-estar na atualidade acontece como resultado de um mundo assentado em hiper-realidades, nas quais as condições originárias do ser humano são esquecidas. Nesse contexto, observa-se que o corpo humano é o foco das alterações mais fundamentais, que merecem nossas reflexões. A situação clínica necessita ser reinventada para dar conta das novas formas de subjetivação, e para isso as contribuições de Michel Henry são profundamente relevantes. Apresentam-se alguns dos conceitos mais fundamentais desse autor em diálogo com a situação clínica.

ABSTRACT: This research aimed to evaluate the mineralization of nitrogen (N) and to define the efficiency index (EI) of N after the addition of organic fertilizers based on cattle manure on the soil under laboratory conditions. A completely randomized statistical design with four replicates was used. The treatments were set as follows: T1) Soil (control); T2) Soil + vermicompost of cattle manure (CMV); T3) Soil + cattle manure and straw compost (CMS); and T4) Soil + cattle manure (CM). Experimental units were constituted by acrylic flasks with 5 x 5cm (height x diameter). Each flask was added with 135g of wet soil and 2.20, 2.45 and 2.27g of CMV, CMS and CM, respectively. Treatments were incubated at 25°C and the amount of mineral N from the soil (N-NH4+ and N-NO2- + N-NO3-) was determined at the beginning of the experiment and after 7, 14, 28, 56 and 112 days of incubation. The highest concentration of N-NO2- + N-NO3- in the soil were observed within the CMS treatment. The EI of N was of 27, 23 and 22% for CMS, CMV and CM, respectively. The mineralization of N from organic fertilizers based on cattle manure occurs on its vast majority within the first 28 days after its addition to the soil. The EI of N from the organic fertilizers based of cattle manure was higher for CMS>CMV>CM and achieved only 80% of what expected for organic fertilizers derived from cattle manure.

RESUMO: O objetivo do presente trabalho foi quantificar e identificar a ocorrência dos principais gêneros de fungos, no solo, material vegetal morto, raiz e parte aérea no capim Tifton 85, adubado com biofertilizante suíno, 7 dias após o início da rebrota. As avaliações foram realizadas, durante seu desenvolvimento (15; 22; 29 e 36 dias após o início da rebrota), no momento do enfardamento e no feno, com 30 dias de armazenamento. O delineamento experimental foi em blocos casualizados com parcelas subdivididas no tempo, com quatro locais de coleta no campo de produção de feno (solo, parte aérea da planta, raiz e material vegetal morto), e 6 tempos de avaliação para parte aérea da planta (15; 22; 29; e 36 dias início da rebrota, no momento do enfardamento e com 30 dias de armazenamento) e quatro tempos de avaliação para solo, raiz e material vegetal morto (15; 22; 29; e 36 dias após início da rebrota). Na contagem e identificação dos gêneros dos fungos referentes a cada parte da planta e solo, foram calculadas as médias e essas submetidas à análise descritiva. Uma maior população fúngica foi observada no material vegetal morto e solo, predominando o gênero Penicillium em todas as partes da planta estudadas.

Introduction : The worldwide increase in the elderly population has highlighted the importance of accidental falls and their consequences.Objective: To perform time-trend analysis of the mortality rate from accidental falls in (1) the city of Florianópolis (2) the state of Santa Catarina and (3) Brazil. Method : A time-series study of data from the Sistema de Informação sobre Mortalidade ("the Mortality Information System") was performed. The variation in mortality caused by accidental falls was estimated using the joinpoint regression method, based on the International Disease Classification (ICD-10), chapter XX, codes W00 to W15 and W17 to W19, from 1997 to 2010. Results : It was observed that in the most recent periods (2005/2008; 2002/2008; 2003/2008), there was a significant increase in mortality rates related to accidental falls in all three regions, and that these rates increased with advancing age. Conclusion : Strategies to prevent accidental falls among the elderly should be aimed, mainly, at those who are 80 and over, the age in which accidental falls result in higher death rates.

Objectives: To verify the prevalence of a low quality of life and analyze the morbidities associated with such a condition among elderly persons registered with the Family Health Strategy of the municipality of Senador Guiomard. Method : A cross-sectional study was performed of elderly persons registered with the Family Health Strategy in the urban area of the municipality of Senador Guiomard in the state of Acre. A comparison between men and women regarding morbidities and quality of life was performed using Pearson's chi-squared test. The associations between the tertiles of quality of life and morbidities were estimated by odds ratio through multivariate logistic regression analysis. Results : There were differences between men and women in the reporting of hypertension (p=0.015), diabetes (p=0.033), in the psychological domain (p=0.009) and in total quality of life (<0.001). Elderly people classified in the lower tertile of the physical and social domains of quality of life were more likely to suffer from hypertension, cardiovascular disorders and anemia. Those in the lower tertile of the psychological domain were also more likely to suffer from hypertension, cardiovascular disorders and insomnia, as well as anemia. Elderly individuals in the lower overall tertile were more likely to suffer from hypertension, cardiovascular disorders, insomnia and anemia. No statistically significant associations were found for the environmental domain. Conclusion : The total quality of life and the physical, psychological and social domains of quality of life can be considered good indicators of the described morbidities among the elderly. The environmental domain, however, was not a useful indicator.
"Educação para uma vida melhor": trajetórias sociais de docentes negros
Authors: Arboleya Arilda , Ciello Fernando , Meucci Simone
Published: January 2016

A histórica engenharia de exploração e subjugação do trabalho negro no Brasil configurou um circuito de desigualdades sociais reincidente. Esse quadro se mostra claro nos limites estruturais impostos às possibilidades de ascensão social de afrodescendentes ainda hoje verificadas. Este trabalho pretende refletir sobre trajetórias de docentes negros de universidades públicas brasileiras, procurando perceber como a educação aparece instrumentalizada nestes discursos, tensionada entre a busca consciente de superação da condição histórica, os limites socioestruturais da desigualdade formal e simbólica, e a representação de si na composição do mérito. A análise desenvolve-se, mobilizando produções sociológicas acerca da relação entre educação, raça e ascensão social, a partir da análise das estratégias e dos caminhos encontrados pelos sujeitos para enfrentar condições institucionalizadas de preconceito

Objective: To analyze the frequency, body topographic local and the instruments used in women with violent death in the city of Recife and the metropolitan area and in the years from 2000 to 2009. Methods: Data collection was performed at the Institute of Forensic Medicine Persivo Antonio Cunha-PE from March to October 2010. Through a study, of chronological approach, necropsy reports in women residing in the Metropolitan Region of Recife-PE in the years 2000 to 2009 were selected. We analyzed the frequency of deaths, the type of instruments used and the topographic location of the lesion. Statistical analysis used the chi-square test or Fisher's exact test, at the significance level of 5%. Results: The frequency distribution showed that the homicide was the 1st reason and represented 36.2% of the total mortality. The accident was the second most common cause with 30.2% followed by the suicides with 5.7%. Regarding the body topographic location, polytrauma presented 29.1% of the occurrences followed by the craniofacial complex with 26.3%. Within the complex craniofacial, the head was the most affected with 27.4%. The face corresponded to 4.2% of the cases. The type of instrument of more incidence was the blunt with 36%, followed by blunt-stabbing with 27%. Conclusion: The homicides demonstrate the magnitude of external causes as cause of premature death among women. The head and neck region is closely linked to the cases of violence against women.
