TV Digital aberta no Brasil

O presente trabalho analisa os importantes desafios que as novas tecnologias e as transformações na sociedade pós-industrial estão impondo à TV digital brasileira e ao seu modelo de negócios. Tem como principal objetivo realizar uma reflexão sobre a viabilidade financeira das emissoras abertas com a chegada da TV digital. Para tanto, analisa o modelo de negócios anterior, da TV analógica, baseado nos comerciais de trinta segundos e como esta forma poderá ser afetada inviabilizando a estrutura de produção e distribuição de conteúdo pelas emissoras abertas digitais. Ainda, busca evidenciar demais fatores que contribuem para a migração da audiência para outras plataformas de distribuição de conteúdo, refutando o senso comum de que o acesso à internet banda larga é a principal causa da queda dos índices de audiência. Este estudo se utiliza de uma ampla bibliografia que extrapola o campo específico da Comunicação e amplia o olhar sobre a indústria televisiva aberta no Brasil, enumerando fragilidades do setor e apontando possíveis estratégias para que a televisão brasileira possa se adaptar à nova estrutura da comunicação que está se formando em nosso país.

O WEBJORNALISMO MEDIADO PELA CULTURA SOCIAL LOCAL ESTUDO COMPARATIVO: BRASIL E PORTUGAL

No momento em que o jornalismo na web enfrenta o desafio de lidar com o fenômeno da desterritorialização da audiência, e ao mesmo tempo com a manutenção de sua marca identitária territorial, esta tese explora a relação da cultura social local com o habitus profissional considerando que o jornalismo é uma atividade social de produção simbólica. No interior dessa temática procura responder se existe diferença significativa do webjornalismo praticado em cidades de culturas sociais distintas, ou se o habitus profissional sobrepujaria essa diferença. Para esse intento foi realizado um estudo comparativo multicasos com jornalistas brasileiros e portugueses de quatro webjornais - Folha Online (São Paulo-SP), Tribuna do Norte (Natal-RN), Jornal de Notícias (Cidade do Porto) e Correio do Minho (Braga). O instrumental metodológico contou com: entrevistas, questionário, mapeamento das características e levantamento de manchetes das home pages. A tese se concentra em compreender o cenário e as inter-relações dos fatores envolvidos no fenômeno da imbricação: prática do webjornalismo e cultura da sociedade. Resultados da pesquisa revelaram, entre outros pontos, que a maioria dos profissionais concorda que a prática do jornalismo na web é muito afeita ao journaliste assis que não vai a campo, permanecendo na redação para tratar apenas o material recebido. Apontou ainda que e as matérias alinhadas ao valor notícia proximidade são pouco presentes nos webjornais considerados de perfil nacional. A principal conclusão é que, embora o webjornalismo siga em alguns pontos os padrões técnicos da cibercomunicação, sua prática diferencia-se ao absorver as características próprias da cultura social da cidade/região onde está situada a sede da empresa jornalística detentora do produto.

The Protocol was implemented in C language, with reference to some protocols developed for automotive use. A circuit to test the communication between the PLC and the Protocol was also implemented.

Parâmetros biológicos de Herpsilochmus pectoralis Sclater 1857 (Aves: Thamnophilidae) em fragmentos de mata atlântica do Nordeste do Brasil

The study of birds represents an important tool for the understanding of the processes involved in behavioral and morphological patterns. The species we have studied belongs to Thamnophilidae family, the third largest family restricted to the Neotropic ecozone. They are popularly known as antbirds and comprise 209 species. A large portion of the species has cryptic behavior, making the acoustic communication an important tool for maintaining contact among birds. Herpsilochmus pectoralis Sclater 1857 has evident sexual dimorphism, measured between 10 and 12 cm height and it is found in forest fragments in the Northeast and it is also categorized as vulnerable to extinction process. This study was conducted in three sandbank fragments on the east coast of the state of Rio Grande do Norte, Brazil. With the help of tape recordings between 2006 and 2012 it was possible to describe and characterize the sing of H. pectoralis. The sing from male birds has more and longer length than the female sing (16% of dimorphism). No differences were found in the dominant frequency between the sexes. We describe four types of calls from this species repertoire. Through capturing with ornithological nets between 2009 and 2012 it was possible to describe and compare the morphology of H. pectoralis. The species have shown lower corporal mass in the dry season. The young birds showed morphometric similarities in comparison to adults. The species has no accentuated dimorphism in their morphometric characteristics. The young ones with flying capabilities have morphometric characteristics of adults, even though they do not show a characteristic adult plumage. The moult pattern in the species is a characteristic of tropical birds, but it shows short reproductive period, typical of temperate species. Even being in the tropical region, the species suffers with seasonal rainfall, which influences their reproductive phenology and moult (remex and rectrix) cycle. Thus, this dissertation provides information on the biology of H. pectoralis to support the understanding of the relationship of this species to the environment and also to know the variations of morphology and vocal aspects, in order to understand patterns and general characteristics of Thamnophilidae.

Semeando a cultura audiovisual no Rio Grande do Norte: a experiência das oficinas de vídeos do Coletivo Caminhos, Comunicação & Cultura

The audiovisual media is an instrument of communication that plays an important role in the cultural, social and political understanding of society. This survey was done intenting to identify the contribution of the audiovisual media to the culture in the Rio Grande do Norte and trying to understand the process of producing audiovisual in this state. To reach the aim, a case report was done regard the activities of Caminhos, Comunicação & Cultura – CC&C – a group that conducts cultural activities in the state since 2006 and has 76% of its activities related to audiovisual production, in which 47% of them, are video workshops. The video workshop project "Sowing Culture", held by the group in the city of Venha Ver/RN in January 2013, was observed and analised from its conception to its realization. The research pursued to reveal how the initiatives of independent producers, such as the CC&C group, can promote the access to audiovisual culture in regions where such knowledge is limited or nonexistent, due to the poor state policies related to the culture. Methodologically, the research was structured by performing a historical and descriptive analysis of hypothetical-deductive method through participant observation. For the conceptual and theoretical development, it was addressed the Sociability, Ethnography and media activism. The research proved that the independent audiovisual producers are promoting changes in the RN audiovisual practices. Before the background featured in the research, it is proposed a prognostic from researching to opening the RN Audiovisual Observatory, a communicational tool projected as space of sharing information, thinking, speaking, contacting and promoting the audiovisual productions of the state.

Percepção da equipe de saúde, discentes e usuários sobre a comunicação com indivíduos surdos na atenção primária

The study aimed to identify in the professionals and students of health courses that work in a health Basic Unit in the city of Natal/RN their perceptions of the care of deaf patients, and with the population's needs with hearing loss in relation to health care. This is a cross-sectional, exploratory, descriptive study, conducted between April to July 2014, with a population composed of 21 health professionals, 17 students and 8 deaf users. For data collection, we used a structured questionnaire with open and closed questions applied to groups composed of health professionals (doctors, dentists, nurses and health workers) and students of medical schools, nursing, physical education, nutrition and social service. The professionals/students answered a semi-structured questionnaire with open and closed questions concerning the possible difficulties the care of the deaf and hearing impaired. Data collection with deaf users was conducted through filmed interview for the Brazilian Sign Language (Libras) could be interpreted as to the Portuguese by the researcher. With the latter it was conducted a survey of their reactions when looking for a care in the health service. Regarding the profile of identification of the subjects, it was analyzed by simple descriptive statistics (absolute and relative frequencies). The open questions were analyzed through the content analysis technique which allowed the categorization process preserving all the points raised in the discussion so that the lines were representative of the whole. When asked about the professionals and students attitude used to communicate with deaf patients possible the following categories emerged: the "writing", the "gestures" and the "third party assistance". With regard of the deaf, when asked about their experiences in seeking care in health, the elucidated categories were: "quality of care to the hearing impaired", "communication with the hearing impaired adequacy" and "dependence on third parties." The closed questions were measured and adapted to the 5 degrees of variation Likert Scale, which comprised three of these issues: degree of difficulty in communication to meet a patient with hearing loss (minimum to great difficulty); feeling of comfort while using sign language (minimum to severe discomfort); and knowledge of the Law 10.436, which provides for the Brazilian Sign Language (Libras) (low knowledge to entirely clear). The data collected with professionals and students revealed some misunderstanding and discomfort in health care for deaf patients, reality also evidenced in the opinion of the deaf participants. This study revealed problems in communication, resulting in negative consequences in serving this population. This diagnosis may be relevant to public policy development and curriculum guidelines essential to the training of health professionals, inclusion and improving assistance to deaf.

A construção medial no português do Brasil: usos no padrão reclamação digital

This thesis examines the medial construction of the Portuguese of Brazil (PB). It is a construction which describes a causative event in which a non-human subject participant is affected by an action that does not originate from itself. Thus, we are interested in investigating this type of construction, its specific characteristics, motivations and discursive context from its semantic- cognitive and discoursive - pragmatic functions. The research questions are: what is the prototypical structural configuration of the medial construction (MC) in the Portuguese of Brazil? What are its specific discoursive functions? What is the degree of MC transitivity based on the properties proposed by Hopper and Thompson (1980)? We assume that the medial construction has its own structure which particularizes its significant dimension, thus ensuring a certain distance between the one in charge of the event and the affected entity. The theoretical and methodological assumptions is founded on Usage-based Functional Linguistics (FURTADO DA CUNHA; BISPO; SILVA, 2013). It is a research of qualitative- interpretative nature that has prioritized the analysis of occurrences arising from texts produced by users of the Brazilian Portuguese language in effective communicative situation. The database for this study is electronic texts available on the website www.reclameaqui.com.br. The results revealed the existence of different configurations of the medial construction in the Brazilian Portuguese, having as prototypical the one formed by SN + V. From the morphosyntactic and semantic point of view, the construction expresses a subject affected by an action that does not part from itself. As for the pragmatic aspect, the construction expresses an event that seems to have the purpose to emphasize the affected argument and to ignore, intentionally or not, the agent or the causative, since it is irrelevant to the speaker/ listener in the contextual situation.

A prescrição de medicamentos por enfermeiros na atenção primária à saúde no Brasil: caracterização, normatização, formação e lições aprendidas.

O papel do enfermeiro como prescritor vem se ampliando em muitos países nos últimos anos, em diferentes situações e amplitudes de ação, se configurando como prática avançada na enfermagem. No Brasil, a prescrição de medicamentos por enfermeiros está prevista na Lei do Exercício Profissional desde 1986, e permite a esse profissional, a prescrição de medicamentos estabelecidos em programas de saúde pública. Esse estudo tem como objetivo geral analisar as determinações e perspectivas da prescrição de medicamentos por enfermeiros nos protocolos da Estratégia Saúde da Família. Os objetivos específicos são: apreender a atual situação internacional da prescrição de medicamentos por enfermeiros em comparação a essa prática no Brasil identificando semelhanças e diferenças; identificar os contornos legais e normativos da prescrição de medicamentos por enfermeiros no Brasil apontando sua história, tendências e desafios; caracterizar o modelo de prescrição de medicamentos por enfermeiros nos protocolos de Atenção Primária à Saúde no Brasil; investigar possíveis lacunas entre formação, capacitação, autoavaliação e prática da prescrição de medicamentos na Atenção Primária à Saúde na perspectiva do enfermeiro. Trata-se de Estudo de Caso Exemplar com abordagem qualitativa através de Revisão Bibliográfica, Análise Documental e Grupo Focal com enfermeiros. A análise dos dados deu-se por meio da Análise de Conteúdo e Análise Qualitativa de Conteúdo. Os resultados revelam que a categoria da enfermagem contribuiu para a legalização da prescrição, porém não para a sua legitimação; na Atenção Primária à Saúde, essa atribuição está consolidada por meio de protocolos e legislação, embora sem estratégia clara de acompanhamento pelo Ministério da Saúde; observa-se resistência em algumas normatizações dentro do setor saúde. Quanto aos protocolos, observou-se não há exigência de pré-requisitos na maioria deles; há possibilidade de diagnóstico pelo enfermeiro na gravidez, nutrição infantil e doenças sexualmente transmissíveis; observou-se variados graus de autonomia; amplo grupo de medicamentos prescritos por enfermeiros. Dos 37 participantes do Grupo Focal, 97,3% eram do sexo feminino; 54% formados há menos de 10 anos, 27% entre 10 e 20 anos, 16,2% há mais de 20 anos; 83,8% com especialização em Saúde Pública. Todos os enfermeiros relataram insuficiência da disciplina de farmacologia para instrumentalizar a prática prescritiva. Destacou-se a necessidade de pós-graduação; a importância da experiência clínica; falta de discussões e capacitação. Apenas alguns se autoavaliaram como competentes para prescrever, outros revelam medo de reação adversa a medicamentos. Conclui-se que há tendência da prescrição de medicamento por enfermeiros permanecer apenas na legalidade e o principal desafio é alcançar a legitimidade. Confirma-se uma prática prescritiva sem requisitos, diversidade de orientações induzindo a multiplicidade de ações que pode afetar a qualidade da prescrição. Há lacunas entre formação, capacitações e exigências cotidianas da prescrição de medicamentos por enfermeiros na Atenção Primária à Saúde. No Brasil se faz premente pesquisa para avaliar o impacto, a qualidade e a segurança da prescrição de medicamentos por enfermeiros. A experiência internacional sugere também que essa prescrição deve ser apoiada pelo coletivo de enfermeiros, com robusto plano de capacitação nacional, além de governança e apoio local.

O controle da tuberculose no contexto da atenção primária à saúde no Brasil

O Brasil é um dos países que concentram 80% da carga de tuberculose no mundo. No contexto da atenção primária brasileira, fatores interferem para que as equipes de saúde da família possam incorporar as atividades de controle da doença no processo de trabalho. O controle da doença depende da forma como os serviços de saúde estão organizados para garantir o acesso ao diagnóstico precoce e ao tratamento. Esse estudo tem como objetivo geral analisar o controle da tuberculose no contexto da atenção primária à saúde no Brasil. Os objetivos específicos são comparar o tratamento diretamente observado com o regime autoadministrado em pessoas com tuberculose; Verificar se o Programa Nacional de Controle da Tuberculose é avaliável e elaborar um modelo teórico e lógico para avaliação deste programa; avaliar a relação entre porte populacional dos municípios e as características de estrutura e processo de cuidado a pacientes de tuberculose na atenção primária no Brasil. Realizou-se uma revisão sistemática, seguida de um estudo de avaliabilidade e de um estudo transversal. Os achados da revisão sistemática revelam que não houve diferença significativa entre os grupos de tratamento (observado e não observado) para cura (OR 1,06. IC95% 0,75 - 1,50) e para conclusão do tratamento (OR 1,64, IC 95% 0,79 - 3,42). Menor abandono no grupo com tratamento supervisionado e não houve diferença estatisticamente significativa entre os grupos (OR 0,73, CI 95% 0,58-0,92). O risco de morte foi maior no regime de tratamento autoadministrado (OR 1,49 IC 95% 1,03 - 2,45). A hetorogeinadade entre os estudos analisados não permite afirmar que nao há diferença estatisticamente significativa para cura e tratamento concluído. A pré-avaliação do Programa de Controle de Tuberculose possibilitou a descrição do Programa, elaboração e pactuação do modelo lógico e a matriz de relevância dos indicadores. Caracterizou-se os seus elementos estruturantes, definição de indicadores de estrutura e processo, além das perguntas avaliativas. Uma avaliação somativa com enfoque na análise dos efeitos da intervenção de controle da tuberculose é recomendada. A avaliação das características de estrutura e processo de cuidado à pessoa com tuberculose revelou melhor desempenho para as equipes de atenção básica de municípios classificados como metrópole no acesso, coordenação do cuidado e qualidade técnica da atenção. Em relação ao acesso: 98,5% acolhimento a demanda espontânea; 95,8% programação de consultas. Na coordenação do cuidado, 93,2% existência de protocolo para tuberculose. Quanto a qualidade técnica da atenção à tuberculose verifica-se que 93,4% acompanhamento de tratamento diretamente observado, 95,8% com busca ativa de faltosos ao tratamento, 64,0% oferta de ações educativas, 91,3% busca ativa de sintomáticos respiratórios. Cabe destacar que metrópoles apresentaram maior tempo médio de espera para escuta/acolhimento (24,41 minutos); para consulta previamente agendada (23,52 dias); para consulta em pneumologia (87,12 dias). Percebem-se fragilidades na estrutura e processo da atenção à tuberculose, principalmente no controle especializado da doença e na qualidade técnica entre os municípios. Recomenda-se reforço, particularmente na qualidade técnica para aumentar a cobertura de acompanhamento do tratamento, busca de sintomáticos respiratórios e das ações educativas.

Comunicação pública e acesso à informação: o interesse público presente nas produções da assessoria de imprensa da prefeitura de Santarém (PA)

Public communication is based on the public interest and the effective democratization of communication in publics agencies. Access to information is the base for this is materializes solidly, helping even in formation as an individual. The work of the press office is the instrument for the Public Communication and access to information is guaranteed to society , since one of the goals of the press officer is to be committed to media , providing it material quality and depth , benefiting so the citizen. The research the look exactly on reflections on the topics listed above. The purpose of this study was to analyze the news published in Fanpage and Santarem Town Hall site, in western Para, meet the demands of Public Communication and the precepts of the Access to Information Law (AIL), starting the questioning until point to Santarem Town Hall works to public communication. For this analysis, we developed a work using the techniques of bibliographic and descriptive research. Such referrals have served as a starting point for fieldwork and for exhibition on the concepts of Public Communication of Access to Information Law, Organizational Communication and Press office. The research was considered, also, because document was to identify and verify the documents with a specific purpose. This research was lifting a quantitative survey to support the qualitative analysis of the object. So considering its features is that it was monitor the Fanpage and the Town Hall site, through a specific tool and then the analysis of posts, searching to observe public communication accomplished in the Town Hall of Santarem, on the Internet, especially social media and corporate website. The methodology helped obtain indicators that allowed add knowledge about the production of the Town Hall press office, and identify if the press office productions meet AIL and Public Communication. Finally, it was suggested in this study the elaboration a strategic script of communication because it scales the actions and policies of the Santarem city, allowing citizen participation. For this, too, it suggested the training of Santarem municipal government communication team as a strategy. This training consists of speeches and wheels conversations with all the press officer of the town hall, including the secretariats.

Impacto na epidemiologia da sepse tardia após a mudança do protocolo de antimicrobianos em uma UTIN de um serviço universitário

Advances in neonatology resulted in reducing the mortality rate and the consequent increase in survival of newborn pre terms (PTN). On the other hand, there was also a considerable increase in the risk of developing health care-related infection (HAI) in its most invasive, especially for bloodstream. This situation is worrying, and prevent the occurrence of it is a challenge and becomes one of the priorities in the Neonatal Intensive Care Unit (NICU). Sepsis is the main cause of death in critical neonates and affects more than one million newborns each year, representing 40% of all deaths in neonates. The incidence of late sepsis can reach 50% in NICUs. Currently the major responsible for the occurrence of sepsis in developed countries is the coagulase negative Staphylococcus (CoNS), followed by S. aureus. The cases of HAIs caused by resistant isolates for major classes of antimicrobial agents have been increasingly frequent in the NICU. Therefore, vancomycin has to be prescribed more frequently, and, today, the first option in the treatment of bloodstream infections by resistant Staphylococcus. The objectives of this study were to assess the impact on late sepsis in epidemiology III NICU after the change of the use of antimicrobials protocol; check the frequency of multiresistant microorganisms; assess the number of neonates who came to death. This study was conducted in NICU Level III HC-UFU. three study groups were formed based on the use of the proposed late sepsis treatment protocol, with 216 belonging to the period A, 207 B and 209 to the C. The work was divided into three stages: Period A: data collected from neonates admitted to the unit between September 2010 to August 2011. was using treatment of late sepsis: with oxacillin and gentamicin, oxacillin and amikacin, oxacillin and cefotaxime. Period B: data were collected from March 2012 to February 2013. Data collection was started six months after protocol change. Due to the higher prevalence of CoNS, the initial protocol was changed to vancomycin and cefotaxime. Period C: data were collected from newborns inteerne in the unit from September 2013 to August 2014. Data collection was started six months after the protocol change, which occurred in March 2013. From the 632 neonates included in this study, 511 (80,8%) came from the gynecology and obstetrics department of the HC-UFU. The mean gestational age was 33 weeks and the prevailing sex was male (55,7%). Seventy-nine percent of the studied neonates were hospitalized at the NICU HC-UFU III because of complications related to the respiratory system. Suspicion of sepsis took to hospitalization in the unit of 1,9% of newborns. In general, the infection rate was 34,5%, and the most frequent infectious sepsis syndrome 81,2%. There was a tendency to reduce the number of neonates who died between periods A 11 and C (p = 0,053). From the 176 cases of late sepsis, 73 were clinical sepsis and 103 had laboratory confirmation, with greater representation of Gram positive bacteria, which corresponded to 67.2% of the isolates and CoNS the most frequent micro-organism (91,5%). There was a statistically significant difference in the reduction of isolation of Gram positive microorganisms between periods A and C (p = 0,0365) as well as in reducing multidrug-resistant CoNS (A and B period p = 0,0462 and A and C period, p = 0,158). This study concluded that: the CoNS was the main microorganism responsible for the occurrence of late sepsis in neonates in the NICU of HC-UFU; the main risk factors for the occurrence of late sepsis were: birth weight <1500 g, use of PICC and CUV, need for mechanical ventilation and parenteral nutrition, SNAPPE> 24 and length of stay more than seven days; the new empirical treatment protocol late sepsis, based on the use of vancomycin associated cefepime, it was effective, since promoted a reduction in insulation CoNS blood cultures between the pre and post implementation of the Protocol (A and C, respectively); just as there was a reduction in the number of newborns who evolved to death between periods A and C.

Efeito da geometria do implante dentário e do protocolo de fresagem óssea na estabilidade primária e na osseointegração inicial: estudo experimental em cães

CHAPTER 1 - This study histologically evaluated two implant designs: a classic thread design versus another specifically designed for healing chamber formation placed with two drilling protocols. Forty dental implants (4.1 mm diameter) with two different macrogeometries were inserted in the tibia of 10 Beagle dogs, and maximum insertion torque was recorded. Drilling techniques were: until 3.75 mm (regular-group); and until 4.0 mm diameter (overdrillinggroup) for both implant designs. At 2 and 4 weeks, samples were retrieved and processed for histomorphometric analysis. For torque and BIC (bone-to-implant contact) and BAFO (bone area fraction occupied), a general-linear model was employed including instrumentation technique and time in vivo as independent. The insertion torque recorded for each implant design and drilling group significantly decreased as a function of increasing drilling diameter for both implant designs (p<0.001). No significant differences were detected between implant designs for each drilling technique (p>0.18). A significant increase in BIC was observed from 2 to 4 weeks for both implants placed with the overdrilling technique (p<0.03) only, but not for those placed in the 3.75 mm drilling sites (p>0.32). Despite the differences between implant designs and drilling technique an intramembranous-like healing mode with newly formed woven bone prevailed. CHAPTER 2 - The objective of this preliminary histologic study was to determine whether the alteration of drilling protocols (oversized, intermediate, undersized drilling) present different biologic responses at early healing periods of 2 weeks in vivo in a beagle dog model. Ten beagle dogs were acquired and subjected to surgeries in the tibia 2 weeks before euthanasia. During surgery, 3 implants, 4 mm in diameter by 10 mm in length, were placed in bone sites drilled to 3.5 mm, 3.75 mm, and 4.0 mm in final diameter. The insertion and removal torque was recorded for all samples. Statistical significance was set to 95% level of confidence and the number of dogs was considered as the statistical unit for all comparisons. For the torque and BIC and BAFO, a general linear model was employed including instrumentation technique and time in vivo as independent. Overall, the insertion torque increased as a function of drilling diameter from 4.0 mm, to 3.75 mm, to 3.5 mm, with a significant difference in torque levels between all groups (p<0.001). Statistical assessment of BIC and BAFO showed significantly higher values for the 3.75 mm (recommended) drilling group was observed relative to the other two groups (p<0.001). Different drilling dimensions resulted in variations in insertion torque values (primary stability) and different pattern of healing and interfacial remodeling was observed for the different groups. CHAPTER 3 - The present study evaluated the effect of different drilling dimensions (undersized, regular, and oversized) in the insertion and removal torques of dental implants in a beagle dog model. Six beagle dogs were acquired and subjected to bilateral surgeries in the radii 1 and 3 weeks before euthanasia. During surgery, 3 implants, 4 mm in diameter by 10 mm in length, were placed in bone sites drilled to 3.2 mm, 3.5 mm, and 3.8 mm in final diameter. The insertion and removal torque was recorded for all samples. Statistical analysis was performed by paired t tests for repeated measures and by t tests assuming unequal variances (all at the 95% level of significance). Overall, the insertion torque and removal torque levels obtained were inversely proportional to the drilling dimension, with a significant difference detected between the 3.2 mm and 3.5 mm relative to the 3.8 mm groups (P < 0.03). Although insertion torque–removal torque paired observations was statis- tically maintained for the 3.5 mm and 3.8 mm groups, a significant decrease in removal torque values relative to insertion torque levels was observed for the 3.2 mm group. A different pattern of healing and interfacial remodeling was observed for the different groups. Different drilling dimensions resulted in variations in insertion torque values (primary stability) and stability maintenance over the first weeks of bone healing.

A Influência do endosso de blogueiras no comportamento das consumidoras de moda no Brasil

The study about the celebrity endorsement has relevance for both the academia and businesses seeking to retain and attract customers through marketing communications. However, most researches conducted analyzes celebrities from the artistic or sports, and study the endorsement in print media or on TV. Few studies analyze the endorsement of influencers in social media. Observing this gap, the aim of this study is to verify if the endorsement of fashion bloggers influence on purchase intention of Brazilian consumers. In addition, other factors were analyzed for better understanding of the fashion consumer behavior: evaluation of the product, brand awareness, brand loyalty, product quality, involvement with fashion, and credibility of the endorser. Therefore, it held two studies. The first consisted of a qualitative exploratory research, which used focus groups to identify and understand how social media affect the behavior of consumers of fashion products. Among the main results of this study, we highlight the Instagram appointed unanimously as the main social media used by respondents for information on fashion, and the mention of blogger Thássia Naves as the main source of fashion reference in social media. In the second study was undertaken an experiment in which half of the sample had access to the image of a dress used by the blogger Thássia Naves on her Instagram, while the other half had access to dress image disclosed at the online store website of the product brand. The number of valid responses considered for the study was 465. To test the hypotheses of the study, we applied the t test for independent samples and ANOVA test for more than two groups. The survey results supported 5 of 8 hypotheses proposed. which were: The endorsement of the fashion blogger has a positive effect on purchase intention of the endorsed product (H1); The endorsement of the fashion blogger has a positive effect on the evaluation of the endorsed product (H2); The credibility of the fashion blogger has a positive effect on purchase intention of the endorsed product (H3); The credibility of the fashion blogger has a positive effect on the evaluation of the endorsed product (H4); and the credibility of the fashion blogger has a positive effect on brand awareness (H5). The other hypotheses have been disproved: The credibility of the fashion blogger has a positive effect on brand loyalty (H6); The credibility of the fashion blogger has a positive effect on the perception of quality (H7); and the credibility of the fashion blogger has a positive effect on involvement with fashion (H8).Within the scope of further analysis, it was found that involvement with fashion positively interfere in purchase intent, the evaluation of the product, brand awareness, loyalty to the brand, the pursuit of product quality and credibility of the endorser. Moreover, it was found that the frequency of access to Instagram for fashion information positively affects the purchase intention, in evaluating the product, the brand awareness in brand loyalty, involvement with fashion, and credibility endorser.
