Such aspects are related to the entrepreneur's strategic articulation as the general configuration of Front Office and Back Office, client's communication improvement, the use of web, client fidelity, disintermediation of activities and cultural activities adaptation on the services offering

A Ergonomia, a Cidade e os Ambientes Interiores: reflexões sobre ambiências, espaço e saúde para o idoso

O presente trabalho apresenta reflexões sobre questões específicas que envolvem os aspectos ergonômicos relacionados às necessidades de cuidados para pessoas idosas em ambientes urbanos das cidades contemporâneas. Os objetivos desse estudo foram trazer à luz a discussão sobre as diversas possibilidades de atuação dos designers de interiores e arquitetos em relação à acessibilidade voltada para o público idoso; abordar alguns aspectos que demandem especial atenção ao projeto do espaço construído voltado ao idoso e, ao mesmo tempo, refletir sobre aspectos projetuais ergonômicos que possibilitem auxílio para o bem-estar da pessoa idosa. Estes aspectos estão relacionados ao estudo do cotidiano e do ordinário previstos na pesquisa qualitativa possíveis de se conhecer quando se refere aos objetos mais ordinários da existência ordinária, sobretudo na atenção às necessidades dos idosos. Pode-se dizer assim que são objetos privilegiados pela sua própria dimensão de relevância para o cotidiano do usuário, aqui referido aos idosos particularmente situados. Aspectos que se relacionam à história da vida cotidiana sem, no entanto, poder ser reduzido em sua função privilegiada de segurança, conforto e bem estar de cada usuário.

Comparision of the direct costs between the constructive processes using reinforced concrete and structural mansory with ceramics and concrete block - case study

The housing deficit in Brazil and the government openness to home financing have increased investment by construction companies in the construction of social housing. Structural masonry has become a great option as it is a fast and economical construction process. Through a case study, it was compared the costs of a group of services in each following construction processes: reinforced concrete with ceramic masonry blocks, structural masonry with concrete blocks and structural masonry with ceramic blocks. The services evaluated were: formwork/stanchions, steel, concrete/grout, masonry blocks and coating. It was observed an economy, regarding costs, of structural masonry with concrete blocks; having a total difference of 17% when compared with the reinforced concrete constructive process. The structural masonry with ceramic blocks resulted in a 7% cost reduction when compared to the reinforced concrete structure

Impact of public health and higher education policies on the profile of final-year Brazilian dental students : challenges and future developments

Introduction: Brazil has experienced transformations in higher education and health services, including launching more inclusive public policies focused on these two areas. Objective: To evaluate the profile of final-year dental students from a Brazilian public university from 2010 to 2019, accompanied by changes in public health and higher education policies. Methods: A prospective observacional study was carried out with final-year dental students. A self-applicable semi-structured questionnaire was applied. Result: Six-hundred and seventy-seven students participated, of which 71.5% were women, 72.9% aged between 21 and 25 years, 96.2% single, and 96.4% were without children. Over ten years, it was possible to identify trends in the profile explained by implementing public policies toward more inclusive access to Brazilian higher educa tion by socioeconomically disadvantaged individuals. Students who completed the course between 2018 and 2019 did not have the state capital city (the wealthiest area) as their origin city and had lower parental education and income levels than dental students graduating between 2010 and 2011. Moreover, working as a primary care dentist in the Brazilian National Health System was considered a professional possibility by 61.4% of the students, and has gained prominence significantly over time, ranging from 21.1% in 2010 to 72.9% in 2019 (p< .05). Conclusion: Over the study period, concomitantly to advances in public health and higher education policies in Brazil, more diverse access to public dental education was observed, allowing students from low socioeconomic positions to take the education. Changes have also impacted the students' perspectives regarding the need for post graduate training and a career in public health dentistry. However, these trends need to be consolidated, and public policies continued and strengthened

QUALIDADE DA CARNE DE AVES DA RAÇA RODHE ISLAND RED CRIADAS EM SISTEMA ALTERNATIVO

Objetivou-se caracterizar a qualidade da carne de aves da raça Rodhe Island Red em função da diferença do tipo de corte e sexo. Foram utilizadas 30 aves em delineamento inteiramente casualizado em esquema fatorial (2 x 2), sendo dois cortes (peito e coxa) e dois sexos, com cinco repetições por tratamento. As aves foram abatidas aos 105 dias para realização das análises físico-químicas, composição centesimal e perfil lipídico do peito e coxa. A coxa apresentou maior média de pH final, teor de vermelho (a*) e força de cisalhamento (FC). Para luminosidade (L*), o peito obteve a maior média e as fêmeas maior média de FC. A coxa apresentou maior teor de extrato etéreo (EE) e umidade. O peito apresentou maior média de ácidos graxos saturados. As fêmeas obtiveram maior quantidade de ?3 e menor relação ?6/?3. Foi observado maior índice de trombogenicidade no peito. A coxa mostrou menor conteúdo de ácidos graxos saturados e menor índice de trombogenicidade. As fêmeas apresentaram maior teor de ?3. O tipo de corte demonstrou maior influência que o sexo sobre os parâmetros estudados e a coxa apresentou melhores aspectos físico-químicos e de perfil lipídico para carne de aves neste sistema de produção relacionados à qualidade de carne desejável pelos consumidores. Palavras-chave: ácido graxo; aterogenicidade; cor; força de cisalhamento; trombogenicidade

Treinamento com pesos e indicadores de agilidade de mulheres idosas

O presente estudo teve como objetivo analisar os efeitos de diferentes tipos de treinamentos sobre o nível de agilidade de mulheres idosas. Foram selecionadas 42 mulheres idosas saudáveis e ativas fisicamente, divididas em três grupos: grupo treinamento com pesos (GTP, n=14), grupo resistência muscular localizada (GRML, n=14), e grupo controle (GC, n=14). Os programas tiveram duração de 12 semanas, com freqüência de três sessões em dias alternados. O indicador de agilidade foi avaliado por meio de um teste de agilidade adaptado da AAHPERD. Os resultados mostram diferença estatisticamente significante no indicador de agilidade somente para o GTP, o GRML melhorou o tempo obtido no teste, embora de maneira não significativa. Podemos concluir que o treinamento com pesos parece ter influenciado preterivelmente a agilidade de mulheres idosas, podendo contribuir para a manutenção da autonomia e da agilidade desta população

Molecular Electrostatic Potential and Chemometric Techniques as Tools to Design Bioactive Compounds

In this chapter, firstly, we briefly review aspects of the approximation of quantum chemistry, molecular electrostatic potential (MEP), and chemometrics techniques, which are accredited as important tools in the development of chemical science and are frequently used in the study and design of bioactive compounds. Ultimately, we use MEP and pattern recognition (PR) techniques as tools to design nitrofuran compounds with biological activity against Trypanosoma cruzi (T. cruzi). PR models (PCA, HCA, KNN, SDA, and SIMCA) were constructed and demonstrated that 23 nitrofurans can be classified into two classes or groups: more active and less active according to their degrees of activity against T. cruzi. Properties such as charge on the N atom of the nitro group (QN1); the difference between the highest occupied molecular orbital (HOMO) energy and the lowest unoccupied molecular orbital (LUMO) energy (GAP energy); molecular representation of structure based on electron diffraction code of signal 5, unweighted (Mor05u); and Moriguchi water–octanol partition coefficient (MlogP) are responsible for the classification into more active and less active studied nitrofurans. It is interesting to notice that these properties represent three distinct classes of interactions between the nitrofurans and the biological receptor: electronic (QN1 and GAP energy), steric (Mor05u), and hydrophobic (MlogP). The results of the application of PR models on the validation set evidenced two nitrofuran compounds (compounds 25 and 30) as more promising for synthesis and biological assays, which in the future can be used to validate our PR models

COVID-19 infodemic and impacts on the mental health of older people : cross-sectional multicenter survey study

Background: The COVID-19 pandemic received widespread media coverage due to its novelty, an early lack of data, and the rapid rise in deaths and cases. This excessive coverage created a secondary “infodemic” that was considered to be a serious public and mental health problem by the World Health Organization and the international scientific community. The infodemic particularly affected older individuals, specifically those who are vulnerable to misinformation due to political positions, low interpretive and critical analysis capacity, and limited technical-scientific knowledge. Thus, it is important to understand older people’s reaction to COVID-19 information disseminated by the media and the effect on their lives and mental health. Objective: We aimed to describe the profile of exposure to COVID-19 information among older Brazilian individuals and the impact on their mental health, perceived stress, and the presence of generalized anxiety disorder (GAD). Methods: This cross-sectional, exploratory study surveyed 3307 older Brazilians via the web, social networks, and email between July 2020 and March 2021. Descriptive analysis and bivariate analysis were performed to estimate associations of interest. Results: Major proportions of the 3307 participants were aged 60 to 64 years (n=1285, 38.9%), female (n=2250, 68.4%), and married (n=1835, 55.5%) and self-identified as White (n=2364, 71.5%). Only 295 (8.9%) had never started or completed a basic education. COVID-19 information was mainly accessed on television (n=2680, 81.1%) and social networks (n=1943, 58.8%). Television exposure was ≥3 hours in 1301 (39.3%) participants, social network use was 2 to 5 hours in 1084 (32.8%) participants, and radio exposure was ≥1 hour in 1223 (37%) participants. Frequency of exposure to social networks was significantly associated with perceived stress (P=.04) and GAD (P=.01). A Bonferroni post hoc test revealed significantly different perceived stress in participants who were exposed to social networks for 1 hour (P=.04) and those who had no exposure (P=.04). A crude linear regression showed that “some” social media use (P=.02) and 1 hour of exposure to social media (P<.001) were associated with perceived stress. Adjusting for sociodemographic variables revealed no associations with this outcome variable. In a crude logistic regression, some social media use (P<.001) and 2 to 5 hours of exposure to social media (P=.03) were associated with GAD. Adjusting for the indicated variables showed that some social network use (P<.001) and 1 hour (P=.04) and 2 to 5 hours (P=.03) of exposure to social media were associated with GAD. Conclusions: Older people, especially women, were often exposed to COVID-19–related information through television and social networks; this affected their mental health, specifically GAD and stress. Thus, the impact of the infodemic should be considered during anamnesis for older people, so that they can share their feelings about it and receive appropriate psychosocial care

Impact of genetic variations in the WNT family members and RUNX2 on dental and skeletal maturation: a cross-sectional study

Background This study evaluated if genetic variations in the WNT family members and RUNX2 are associated with craniofacial maturation, investigating dental and skeletal maturity in children and teenagers. Methods Radiographs from pre-orthodontic treatment of Brazilian patients (7 to 17 years-old) were used to assess dental (panoramic radiographs) and skeletal maturity (cephalometric radiographs). The chronological age (CA) was calculated based on the date of birth and the time the radiographs were performed. For the dental maturity analysis, the Demirjian (1973) method was used and a delta [dental age - chronological age (DA-CA)] was calculated. For the skeletal maturity analysis, the Baccetti et al. (2005) method was used and the patients were classified as “delayed skeletal maturation”, “advanced skeletal maturation” or “normal skeletal maturation”. DNA isolated from buccal cells was used for genotyping of two genetic variations in WNT family genes: rs708111 (G > A) in WNT3A and rs1533767 (G > A) in WNT11; and two genetic variations in RUNX2: rs1200425 (G > A) and rs59983488 (G > T). A statistical analysis was performed and values of p < 0.05 indicated a significant difference. Results There were no associations between dental maturity and genotypes (p > 0.05). In the skeletal maturity analysis, the allele A in the rs708111 (WNT3A) was statistically more frequent in patients with delayed skeletal maturation (Prevalence Ratio = 1.6; 95% Confidence Interval = 1.00 to 2.54; p-value = 0.042). Conclusions The rs708111 in the WNT3A gene impacts on skeletal maturation
