Vocal Self-Perception of Singers During COVID-19 Pandemic.

to compare the self-perception of vocal fatigue and use of singing voice during the COVID-19 pandemic between professional and amateur singers and to relate this self-perception with vocal use characteristics during this period. Participants were 121 singers divided into professional singers group (PSG) (12 men and 20 women) comprising singers who depended exclusively on singing as a profession and an amateur singers group (ASG) (37 men and 52 women) of singers who did not depend exclusively on singing for their livelihood. All answered online questionnaires through Google Forms ®. Sociodemographic and vocal characteristics were investigated before and during the pandemic; symptoms of vocal fatigue were assessed through the vocal fatigue index (VFI); and self-perception of use of singing voice through the evaluation of the ability to sing easily protocol for Brazil (EASE-Br). In the comparison between groups, the PSG presented higher scores of vocal fatigue in fatigue and vocal limitation (P=0.045), vocal restriction (P=0.002), and recovery with vocal rest (P=0.008) domains than did the ASG. There was no difference between the groups regarding the use of singing voice. Based on the relationship between self-perception and vocal use characteristics during the pandemic, it was observed that the presence of vocal complaint was the only factor associated with self-perception of fatigue symptomatology in both groups. Regarding the self-perception of the current status of the singing voice, singing time, the presence of vocal complaints, the need to increase visual concentration, and the perception of vocal worsening during the pandemic were considered predictive for amateur singers. For professional singers, vocal complaints and vocal training were predictors for self-perception of the current status of the singing voice. Professional singers presented with higher scores of vocal fatigue than did amateur singers. The symptomatology of vocal fatigue was associated with the presence of vocal complaints in both groups. However, self-perception of the current status of the singing voice was different between the groups and was associated with vocal training for professional singers and characteristics of vocal demand of singing voice during the pandemic period for amateur singers.

CAN MOBILITY AFFECT GRAMMAR AT THE MORPHOSYNTACTIC LEVEL? A STUDY IN BRAZILIAN PORTUGUESE

In this paper, a study about the presence of the definite article before possessed NP (D-presence) in Brazilian Portuguese is carried out with a sample constituted by sociolinguistic interviews with students from the Federal University of Sergipe (UFS), Brazil, to observe whether the distribution pattern of the variable suggests an effect of mobility in the students’ speech. An analysis is carried out with a sample from the Deslocamentos 2020 dataset, composed of sociolinguistic interviews with college students from Universidade Federal de Sergipe (UFS), balanced for degree of mobility (students from Sergipe, Alagoas, and Bahia), time in the undergraduate program, and sex (n = 60). Results show that D-presence is sensitive to dialectal factor, with D-absence predominating in data from Sergipe and Alagoas, and D-presence predominating in data from Bahia, but it is not sensitive to the integration into the new community considering speakers’ time in the undergraduate program. This result contributes to revealing how mobility affects grammar at the morphosyntactic level.

Persistent musculoskeletal presentations post-chikungunya fever: a case series in a state in northeast Brazil

Chikungunya fever (CF) is an arbovirosis caused by the Chikungunya virus (CHIKV). The main characteristic of CF is joint pain and more than half of infected patients experience chronic conditions. This case series study evaluated the persistent musculoskeletal presentations of CF in a sample of 72 patients with persistent symptoms (≥1 month) after CF confirmed by laboratory tests (detection of CHIKV by polymerase chain reaction [PCR] and/or immunoglobulin [Ig]M and/or IgG). The patients were followed up for 12 months after treatment at the outpatient clinic of the University Hospital of the Federal University of Sergipe (Hospital Universitário da Universidade Federal de Sergipe - HU/UFS). They were evaluated at admission and after 1 month, 2 months, and then every 3 months for up to 12 months. Painful and/or swollen joints, periarticular symptoms, other important findings on physical examination, and visual analogue pain scale (VAS) were evaluated during all consultations. Main results: Among the patients evaluated, 84.7% were female, the mean age was 53.8 years, and the mean duration of musculoskeletal complaints was 6 months. Comorbidities were present in 61.1% of patients and previous musculoskeletal disease was present in 69.4%. The most frequent presentation on admission was polyarticular, which occurred in 76.4% of cases. The most affected joints were the hands, knees, ankles, and feet. VAS on admission was intense in 66.7% of patients. Tenosynovitis was present in 44.5% of patients and was more frequently reported in the ankles. Corticosteroids and chloroquine were administered to 65.3% and 31.98% of patients, respectively. The findings indicated that persistent musculoskeletal presentations occur frequently after CF. These results provide a better understanding of patient profiles, musculoskeletal involvement, and CF progression, and may guide effective strategies for therapeutic management.

TOURISM AND EXTENSION IN HIGHER EDUCATION: The UFS de Braços Abertos project and demystifying percpetions of the university

University extension is an inseparable tool from teaching and research, and aims to popularize science by providing services to society. In higher education in Tourism, extension activities are indispensable in the process of raising citizenship awareness among professionals in the area. Based on these premises, this article reflects on the importance of university extension as a tool for higher education in Tourism, as well as for democratizing access to university, taking as its field of study the project UFS de Braços Abertos. We begin with a report of experience of one of the actions of the project, in partnership with the Física Show, conducted with elementary and high school students from the city of Propriá, in the state of Sergipe/SE. The aims were: i) to critically discuss the common sense vision of the University as a restricted, excluding space that is distant from society, ii) to analyze the importance of the projects UFS de Braços Abertos and Física Show in the career choice of students in Basic Education and iii) to reflect on the importance of university extension projects for academic and professional training on the course in Tourism at Universidade Federal de Sergipe (UFS). As theoretical and methodological contributions, we adopted participant research (GIL, 2008), linked to descriptive research, and a qualitative approach. Our reflections indicate an increasing need to discuss university extension activities, bearing in mind that they provide a practical laboratory where theory and practice can be combined, contributing to students’ academic and professional training. Extension projects also provide opportunities for inclusion of the community outside the walls of UFS. We conclude that since tourism is an activity that encompasses other areas of knowledge, which are necessary for its performance, studies in this area should also include transdisciplinary extension activities inherent to the learning process.

Lizards from the Alto Sertão region of Sergipe state, northeastern Brazil

Abstract We present the first detailed inventory of the lizard fauna of Alto Sertão region, west of Sergipe state, based on three field expeditions carried out by the authors and specimens deposited at the Herpetological Collection of Universidade Federal de Sergipe. The three inventories were carried out between 2010 and 2016, in the municipalities of Canindé de São Francisco, Poço Redondo, Monte Alegre de Sergipe, Nossa Senhora da Glória, and Porto da Folha. In total, we sampled 9,485 lizards of 19 species (10 families) of which 10 are new records for the study area. The most abundant species were Ameivula ocellifera, Tropidurus hispidus and T. semitaeniatus. Thirteen species were considered as widely distributed in Caatinga, five presented a relictual distribution and one was exotic. We suggest that future research focus mainly on non-sampled areas and should prioritize the municipalities of Gararu, Nossa Senhora da Glória and Nossa Senhora de Lourdes since they are localities with little or no sampling records.

A urgência para a realização de atividades educacionais remotas, devido ao contexto pandêmico do coronavírus, instiga reflexões e ações efetivas na educação básica e no ensino superior. Com o intuito de compartilhar conhecimentos e vivências práticas, este artigo, que se apoia em um relato de experiência, apresenta as expectativas, desafios e superações na preparação, execução e avaliação de uma ação de extensão, na modalidade remota, do curso de produção escrita em língua espanhola, oferecido a estudantes da graduação em Letras com habilitação em Espanhol da Universidade Federal de Sergipe (UFS). As professoras-pesquisadoras compreenderam a ação como satisfatória, por motivar a produção escrita e a interação entre os alunos, embora tenham encontrado percalços e, portanto, a necessidade de adaptações para a realização do curso, no que se refere tanto ao empreendimento de recursos tecnológicos (escolha das plataformas para as atividades síncronas e assíncronas), quanto às ações pedagógicas (curadoria do material, adequação ao tempo de aula e à quantidade de atividades semanais e propostas de exercícios mais interativos). Trata-se de um trabalho relevante no que diz respeito à proposta do curso em si e às especificidades do ensino remoto, contribuindo com a divulgação científica de ações que fomentam o estabelecimento e as relações eficazes entre ensino, pesquisa e extensão.

Cell biology for visually impaired people: a study on inclusion methodologies

Introduction: Inclusive Education is a consequence of changes in social attitudes that have been established throughout history. Objective: This study analyzed the conceptions and practices of teachers who taught blind students and the benefits of using a didactic model (3D cell) adapted for these students. Methodology: 10 teachers were selected from the departments of Biology, Chemistry and Morphology at Universidade Federal de Sergipe. As for the 3D cell analysis, three visually impaired students from Biology, Physical Education and Physiotherapy courses were invited. Results: The research demonstrated the main weaknesses in the teacher training process and the little support they receive, thus leading to difficulties in the learning process and the relevance that didactic models can have in this context. Conclusion: Considering that theoretical and methodological foundations of Inclusive Education are based on a conception of quality education for the whole society, a more qualified teachers’ participation is essential to meet the educational needs of all students, with or without disabilities.

As Relações Ciência Tecnologia Sociedade e Ambiente (CTSA) no Ensino de Ciências da Natureza: um mapeamento na Biblioteca Digital Brasileira de Teses e Dissertações no período de 2013 a 2019

A partir da metade do século XX, o desenvolvimento científico-tecnológico se intensificou e a atividade industrial tornou-se mais sofisticada, comprometendo assim, o meio ambiente. A aceleração da degradação ambiental, a pobreza e as relações entre os modos de consumo e produção, fez surgir a tomada de consciência por parte da sociedade para constituir uma visão do ensino que levasse em consideração as relações entre Ciência, Tecnologia, Sociedade e Ambiente (CTSA) para a formação científica e ambiental do cidadão. Com a finalidade de compreender como essas relações são desenvolvidas na área das Ciências da Natureza apresentamos nesse artigo o resultado de uma pesquisa do tipo Estado do Conhecimento realizada na Biblioteca Digital Brasileira de Teses e Dissertações (BDTD) no período de 2013 a 2019 que teve como objetivo conhecer como as relações CTSA vem sendo desenvolvida pelos pesquisadores dessa área do conhecimento. Selecionamos 44 produções que foram analisados de acordo com Fiorentini. Os dados revelaram que a partir do ano 2015 o número de pesquisas variou pouco ao longo dos anos, as instituições de ensino superior que mais desenvolveram pesquisas foram a Universidade Estadual Paulista (Unesp), Universidade Federal Fluminense (UFF) e a Universidade Federal de Sergipe (UFS). As relações CTSA são desenvolvidas pelos pesquisadores, em sua maioria a partir da construção e aplicação de sequências de ensino cuja temática são as questões sociocientíficas.

Morpho-agronomic characterization of sweet potato germplasm

ABSTRACT Sweet potato (Ipomoea batatas) spreads mainly by vegetative propagation, and therefore this vegetable may have duplicate accessions in germplasm banks. The authors aimed to characterize morpho-agronomically the sweet potato germplasm from the Active Germplasm Bank (AGB) of Universidade Federal de Sergipe (UFS).The experiment was carried out at the Research Farm “Campus Rural da UFS”. The experimental design was a randomized block design, testing 73 sweet potato accessions with two replicates and four plants per plot. Morpho-agronomic traits of aboveground part and roots were evaluated. We observed that the leaf lobe type, the number of lobes per leaf, shape of central lobe, and general leaf shape were traits which provided the most variability among the accessions. For damage caused by soil insects, 52 accessions showed tolerance. The accessions presented a range from 0.33 to 2.71 t/ha for dry mass of aboveground part and from 1.20 to 10.89 t/ha for the total productivity of the roots. The high phenotypic variability of this crop shows good prospect for breeding programs.

Discutimos, neste artigo, o uso da tecnologia WebQuest em práticas vivenciadas na disciplina Metodologia do Ensino e Aprendizagem de Línguas, de um curso de Licenciatura em Letras/Espanhol. O objetivo da proposta era que os estudantes pudessem ampliar seus conhecimentos sobre metodologias (com foco no espanhol), melhorar seu nível de letramento digital e refletir sobre a apropriação social das tecnologias digitais no campo do ensino e aprendizagem de línguas. Nas aulas, partimos dos conhecimentos prévios dos alunos e da discussão de obras que tratassem sobre as principais metodologias de ensino e aprendizagem de línguas e de outras que abordassem, em linhas gerais, a questão do letramento digital e, em termos específicos, que versassem sobre a WebQuest. Para tanto, nos apoiamos nos trabalhos de Levy (2010), Xavier (2005) e Dias (2010), dentre outros. Os resultados alcançados foram a criação de WebQuests, o aprofundamento da reflexão sobre a importância do uso pedagógico de tecnologias e a melhora do letramento digital dos estudantes.

Entre silêncios e esquecimentos: o Museu do Homem Sergipano, brasil (2009-2013)

The Museum of Man in Sergipe (MUHSE), linked to the Department of extension and Community Affairs at the Universidade Federal de Sergipe (UFS), began operations in November 1996, occupying up to 2013 a historic building in Aracaju/SE/Brazil. Your long-term exposure was extracted from the book “Texts for the history of Sergipe” (1991). The Museum found his vocation in educational actions aimed at school audiences (Nunes, 2010: 70). Since May 2, 2011, the Museum has been closed to visitors because of the deterioration of the buildings. The objective of this work, in the midst of the process of new signification whereby the MUHSE passes from 2014, seeks to historicize the processes developed at the institution between 2009 and 2013. Before the new proposal redirects, especially on the new semantics of the institution, wonders how the New Museology or Social Museology could serve as a compass to point the horizon. Between memory and oblivion, wouldn't it be better to make the safeguarding of heritage with respect and attention to the contribution of students, faculty, visitors, managers and neighbors to museum space? The work part of participatory observation of documents (institutional Ordinances and Resolutions) and actions at the Museum studied, as well as readings of Mário Moutinho, Paul Ricoeur, Pierre Nora, among others. Keywords: Museum; oblivion; history; Social Museology; new signification.

Molecular characterization of patchouli (Pogostemon spp) germplasm.

Patchouli [Pogostemon cablin (Blanco) Benth.] is an aromatic, herbaceous plant belonging to the Lamiaceae family native to Southeast Asia. Its leaves produce an essential oil regularly used by the perfume and cosmetics industries. However, since patchouli from the Philippines and India were described and named Pogostemon patchouli, there has been a divergence in the identity of these species. The objective of the current study was to study the genetic diversity of patchouli accessions in the Active Germplasm Bank of Universidade Federal de Sergipe using microsatellite and inter simple sequence repeat markers. The results of both types of molecular markers showed that there are two well-defined clusters of accessions that harbor exclusive alleles. It was observed that these two clusters are genetically distant, suggesting that they belong to two different species. Based on the results, two accessions were classified as Pogostemon heyneanus and the remaining accessions were classified as P. cablin.

Ensino de paleontologia: uma abordagem não-formal no Laboratório de Paleontologia da Universidade Federal de Sergipe

O presente estudo objetivou avaliar a contribuição do Laboratório de Paleontologia da Universidade Federal de Sergipe como espaço de educação não-formal, assim como reconhecer este espaço como disseminador de conhecimentos sobre Paleontologia para alunos do 7º ano das escolas públicas municipais de Aracaju. Os alunos tiveram acesso ao acervo fossilífero, através de visitas à exposição, onde foram discutidos conceitos, importância e aplicações do uso dos fósseis como instrumento para a reconstrução de eventos e ambientes pretéritos. Foram analisados 164 textos confeccionados pelos discentes contendo avaliações subjetivas sobre o processo de visitação. Foram analisadas entrevistas, desenvolvidas junto aos professores responsáveis por cada classe, permitindo avaliar as concepções dos docentes sobre a contribuição da visita no processo de ensino-aprendizagem dos seus alunos. Por intermédio da análise qualitativa dos textos e das entrevistas, conclui-se que a exposição, enquanto espaço de educação não-formal, é capaz de difundir os conhecimentos paleontológicos permitindo aprendizado lúdico e interativo.

Molecular typing of Salmonella from Sergipe, Northeastern Brazil, showing the epidemiological relationship between poultry and human infection.

Randomly amplified polymorphic DNA (RAPD) has been widely used for epidemiological and phylogenetic purposes ow-ing to its rapidity and efficiency. The aim of this study was to perform genome typing of Salmonella samples isolated from different sources by RAPD profiling. Thirty-three Salmonella samples from the bacterial collection of the Laboratório de Virologia Comparada, Departamento de Morfologia, Universidade Federal de Sergipe, Brazil, and two standard samples were used. RAPD profiling was conducted using six primers of the Ready-To-Go RAPD system. The amplified products were electro-phoresed on 5% polyacrylamide gel and silver-stained. RAPD analysis resulted in reproducible and stable banding patterns and showed high genetic diversity among the isolated strains. The Primer P1-generated dendrogram showed an epidemiologic relationship between the human and poultry isolated samples, highlighting the usefulness of RAPD for molecular typing and epidemiological studies.

Molecular and chemical characterization of vetiver, Chrysopogon zizanioides (L.) Roberty, germplasm

Due to the economic interests in vetiver, Chrysopogon zizanioides (L.) Roberty, molecular and chemical studies are essential to generate information for its sustainable exploitation. The aim of this study was to undertake a molecular and chemical characterization of vetiver accessions of the active germplasm bank of the Universidade Federal de Sergipe. The molecular characteristics of the accessions were studied using amplified fragment length polymorphism markers, with a total of 14 primer combinations that generated 442 loci, allowing us to observe that these accessions have similar genomes. The vetiver accessions were divided into three distinct groups, where accession UFS-VET005 was the most differentiated and accession UFS-VET004 had the lowest essential oil content (0.70%). The content of the chemical constituents of the essential oils was observed to vary, with a predominance of khusimol, which ranged from 18.97 to 25.02%. It was possible to divide the vetiver accessions into two groups based on chemical composition, and these groups do not correlate with the molecular grouping. Therefore, it is necessary to perform molecular and chemical analyses to characterize vetiver accessions.

2,4-dichlorophenoxyacetic acid as an alternative auxin for rooting of vine rootstock cuttings

Viticulture is an important agricultural activity in semiarid northeastern Brazil, and the quality and ease of vine propagation are very important in this context. This study evaluated the use of 2,4-dichlorophenoxyacetic acid (2,4-D) as an alternative to indolebutyric acid (IBA) in the rooting of vine rootstock cuttings. The trial was conducted at the Universidade Federal de Sergipe (São Cristóvão-SE) between January and March 2010 with cuttings of the rootstocks of 'IAC-766', 'IAC-572', and 'Paulsen 1103' treated with 2,4-D or IBA applied at concentrations of 0, 1000, 2000, or 3000 rng-L-1 for 5 s and planted in a field on washed sand. At 56 days after planting, the percentages of rooted, sprouted, callused, and dead cuttings were evaluated, and also the average number and length of the rooted cuttings. The results showed that 2,4-D was not superior to IBA in the characteristics wanted for the rooting process of the vine rootstock cuttings. The vine rootstocks showed potential for propagation by cutting without auxin application. It was observed that the high concentrations were the worst for the rooting of the cuttings.

Development and characterization of novel microsatellite markers in Hyptis pectinata (Lamiaceae).

A microsatellite-enriched library was constructed and a set of 19 SSR markers were developed to characterize a germplasm collection of Hyptis pectinata (L.) Poit., maintained at the Universidade Federal de Sergipe (UFS). Fifteen markers of 19 ranged from moderately to highly polymorphic. A total of 113 alleles were identified, with a mean of 7.52 alleles per locus. The mean HO and HE were 0.582 and 0.657, respectively. The primers developed were efficient tools for accessing the genetic diversity of the germplasm collection analyzed and may also be useful for other studies involving this species and other species in the genus Hyptis.

Cross-species transferability of microsatellite markers in the genus Lippia

The cross-species transferability of 20 microsatellite markers was tested in the genus Lippia. Eleven markers were polymorphic after screening 19 accessions of Lippia sidoides and Lippia gracilis maintained in the Active Germplasm Bank (AGB) from Universidade Federal de Sergipe. Additionally, 40 accessions of Lippia spp were collected in Sergipe to increase the germplasm bank. A total of 23, 22, and 36 alleles were identified, with an average of 2.3, 2.2, and 3.27 alleles per locus, respectively, for each group. The markers that were used were efficient tools to access genetic diversity in the germplasm bank and will be useful for further research aiming at the conservation and management of these important aromatic species.

Ulcer Due to Chronic Venous Disease: A Sociodemographic Study in Northeastern Brazil

Venous ulcers account for 70% of chronic leg ulcers and affect about 2-7% of the population, causing much socioeconomic impact and reducing patients' quality of life. In this study we aimed to describe the clinical features of venous ulcers and sociodemographic characteristics of patients with ulcers due to chronic venous disease (CVD). This cross-sectional, observational study was conducted at the Vascular Surgery Service, Universidade Federal de Sergipe, in northeastern Brazil. The study included a consecutive series of 154 patients with active venous ulcers (CEAP C6) in the lower limb due to CVD. Sociodemographic characteristics (age, gender, race, monthly income, education, occupation, and caregiver) and clinical data (affected limb, ulcer site, etiopathogenesis, recurrence, and time elapsed since the first episode of ulcer) were collected. A possible correlation of time elapsed since the first episode of ulcer and number of recurrences with primary or secondary etiology was analyzed by Mann-Whitney U-test. Of the 154 patients analyzed, 79% were female, 94% were ethnically black or brown, 90% had a monthly income less than or equal to minimum wage, 47% were illiterate, 35% had not completed elementary school, 50% had informal jobs, 19.5% were retired, and 18.2% received sick pay from the social security system. The mean age was 53.7 years. Both limbs were affected similarly, and venous ulcers were located predominantly on the medial aspect of the leg (84%). The median time elapsed since the first episode of ulcer was 36 months, being significantly higher in patients with venous ulcers of secondary etiology (P < 0.0003). The prevalence of recurrence was also significantly higher in patients with venous ulcers of secondary etiology (P < 0.001). According to CEAP classification, 65% of ulcers were primary (Ep), 94.1% demonstrated reflux involving the superficial system (As), 92% had incompetent perforators (Ap), 35% demonstrated reflux involving the deep system (Ad), and all ulcers showed reflux without obstruction (Pr). Venous ulcers were more prevalent among low-income patients, especially chronic, recurrent ulcers of primary etiology. This finding highlights the need for improvements in patient care and surgical treatment in most cases aimed at ulcer healing and reduced recurrence. Better care would improve patients' quality of life and reduce social security expenditures.
