Authors: Moore Lori , Murphrey Theresa , Degenhart Shannon , Vestal Tom , Loux Shavahn
Published: July 2023

The Animal Health Network is designed to connect state veterinarians with Extension partners and local feed retailers to deliver timely, relevant animal disease-related information to non-commercial livestock and poultry owners. The study reported here explored perceptions of key opinion leaders related to the characteristics of the Network as an innovation. Qualitative interviews conducted with13 stakeholders involved in the implementation of the Network revealed that the relative advantage, complexity, and compatibility of the Network were readily apparent to participants, while trialability and observability were not as pervasive. Findings can assist those attempting to diffuse a concept or idea with similar characteristics.

Authors: Fabus Taylor , Waite Karen , Shelle John , Siegford Janice , Chapin Julie
Published: July 2023

In response to growing interest in equine welfare and the need for 4-H curriculum, a pilot study of equine welfare curriculum was conducted with 4-H clubs (N=15). An overall low response rate of 26.67% was experienced. An online survey was then conducted in order to determine factors affecting involvement. Time constraints for both youth and leaders were among the most commonly cited deterrents to completion. Survey responses also suggested that following a hybrid (of hard copy and online instruction) may increase usability and effectiveness of A Guide to Equine Welfare Assessment.

Authors: Starnes Jane , Feleke Shiferaw , Schaffer Harwood , Tiller Kelly
Published: July 2023

The challenge to meet tobacco's labor requirements by domestic sources has prompted tobacco growers to seek a foreign source of labor through the H-2A program. The H-2A program is the only legally sanctioned program allowing farm employers to bring foreign workers into the country to perform seasonal and temporary agricultural work. The article profiles H-2A program participants in major tobacco growing states. The results will help Extension personnel better understand their constituents' labor needs and inform the design of specific Extension programs and workshops in farm labor management, labor laws and regulations as well as labor cost-saving measures.
Agricultural Energy Information Needs of Cooperative Extension Agricultural Agents and Their Clientele
Authors: Kluchinski Daniel
Published: July 2023

A nationwide survey of Extension agricultural agents was conducted to determine interests and educational needs related to energy and agriculture. Their highest ranked interests were renewable energy (wind, solar), farm system conservation and efficiency, and biodiesel. They perceived their clientele's greatest interests in biodiesel, wind energy, farm system conservation and efficiency, and solar energy. Regional differences were found, but similar interests included renewables, conservation and efficiency, and inputs (feedstocks) rather than outputs (end products) and processes. The results identify and prioritize informational needs and are useful for planning future educational training and developing educational materials on farm energy topics.

Authors: Bailey Elaine , Waite Karen , Wilson Kristen
Published: July 2023

Youth organizations, such as 4-H, need dedicated, knowledgeable adult volunteer leaders. Oftentimes, adults are intimidated to work with youth, either because of questionable understanding of youngsters or due to limited subject knowledge. This is particularly true with volunteers for youth horse organizations. The eXtension HorseQuest CoP (Community of Practice) recognized the need to improve the comfort level and competence of youth horse organization volunteers. Members of the CoP created HALTER, the Horse Adult Leader Training and Education Resource, to address both the youth development training aspects as well as the horse knowledge needs of adult volunteers working with youth organizations.

Collaboration between public and private partners in the food assistance network is critical to reducing hunger. Access to safe, nutritious, and affordable food is a public health concern best addressed through a multi-sector, multi-prong approach. Extension programs across the United States provide community-based responses to hunger and can use their considerable resources to partner with governmental and nonprofit actors to boost participation in federally funded nutrition assistance programs to take full advantage of the dollars already appropriated for hunger relief and to generate economic benefits for communities at large.
Starting a Supplemental Nutrition Assistance Program: Information for Starting This Program at a Farmers Market
Authors: Parsons Megan , Morales Alfonso
Published: July 2023

Farmers markets are important market places offering healthy food sources that can become more accessible for low-income consumers by incorporating Electronic Benefits Transfer (EBT) to facilitate the Supplemental Nutritional Assistance Program (SNAP) (Morales, 2011). We reviewed e-mails sent to the second author via the Farmers Market Coalition Listserv and found that many market managers have questions regarding starting this program. In the process, we found that many questions were asked multiple times, indicating the need for the type of technical assistance provided by Extension professionals. Extension agents can use this information to integrate SNAP into new and existing markets.

Authors: Yazdi Amirhossein , Alvandi Maryam , Shaghaghi Zahra , Hashemi Seyed Hamid , Inanloo Seyed Omid , Hashemi SayedPayam , Mohammadi Tayeb , Akbari Surur
Published: July 2023

Background: Being infected with COVID-19 is a multifaceted syndrome that should be managed in the context of concurrent comorbidities. This study aimed to decipher the influence of cardiovascular diseases (CVDs) in the COVID-19 progression and its outcome. Methods: From a cohort of 184 consecutive CVD patients diagnosed with COVID-19, 86 and 98 cases were placed in the non-severe and severe groups. The clinical, laboratory, and outcome data were compared between two divisions. A logistic regression model was further applied to determine parameters associated with disease severity and outcomes. Results: Patients in the severe group had significantly a higher mean age and body mass index (BMI). Of laboratory parameters, neutrophil/lymphocyte (N/L) ratio, blood urea nitrogen, serum creatinine, troponin I, and creatine kinase-myocardial band increased significantly in the severe group. Heart failure (HF) was the only CVD type that was associated with disease severity and outcome. The overall mortality rate among CVD patients was 24.5%, and patients with age over 75, dyspnea, and lower O2 saturation at the admission time were at risk of an increased chance of death. Conclusion: The mortality rate of COVID patients with underlying CVDs is high, and identifying the factors associated with disease progression is of great value. Obesity and advanced age put cardiovascular patients at the stake of severe disease and poorer outcomes. Dyspnea and hypoxia at the admission time, as well as the N/L ratio, were associated with disease severity and outcome, and chances are that they can be used as suitable predictors for recognizing those who need intensive management care.

Authors: Goudarzi Farjam , Mohammadalipour Adel , Karimi Sheno , Khodadadi Iraj , Shahmohammadi Azin , Goodarzi Mohammad Taghi
Published: July 2023

Background: Adipogenesis is affected by multiple factors, among which all-trans retinoic acid (ATRA) and Ca2+are considered important factors. Objectives: This study aimed to evaluate the effect of calcium, ATRA, and their underlying molecular mechanisms, alone and in combination, on adipocyte differentiation. Methods: Human adipose-derived mesenchymal stem cells (hAD-MSCs) were differentiated into adipocytes and simultaneously exposed to 0.5 μM ATRA or 2.5 mM calcium, or both in combination for 14 days. Results: Higher intracellular Ca2+was observed in both Ca2+and Ca2+plus ATRA groups. Assessment of triglyceride content and glyceraldehyde 3-phosphate dehydrogenase (GAPDH) activity indicated lower differentiation levels in all treatment groups than in the control group. Furthermore, the results demonstrated a higher expression of retinoic acid receptor alpha (RAR-α) and lower expression of peroxisome proliferator-activated receptor γ2 (PPARγ2) and glucose transferase-4 (GLUT4) in the treatment groups as compared with the control group. It is noteworthy that Ca2+plus ATRA treatment caused more significant effects on gene expression levels (P<0.05). Conclusion: In conclusion, combined treatment with Ca2+and ATRA has a more pronounced inhibitory effect on adipocyte differentiation, indicating their cumulative effect.

Authors: Emokpae Mathias Abiodun , Bamidele Winner Oluwarotimi
Published: July 2023

Background: Manganese (Mn) is absolutely necessary for several biological functions in the body, but higher concentrations may be extremely harmful to male reproductive health. Objectives: This study aimed to determine Mn, zinc (Zn), and copper (Cu) levels in serum and seminal plasma and correlate their concentrations with sperm quantity and quality among men investigated for infertility. Methods: A total of 70 infertile males in the age range of 25-45 years and 50 control subjects were evaluated in this study. The semen samples were analyzed by the microscopic technique, while Mn, Zn, and Cu were analyzed using an atomic absorption spectrophotometer. Socio-demographic parameters were obtained using a semi-structured questionnaire. Then, unpaired Student’s t test and chi-square test were used to compare the discrete data between infertile males and controls and categorical data, respectively. Finally, Pearson’s correlation coefficient was employed to correlate measured elements with sperm induces. Results: The sperm count, sperm motility, viability, and serum/seminal plasma Zn and Cu levels were significantly lower (P<0.001), while the Mn and Cu/Zn ratios were significantly higher (P<0.001) among infertile men than control subjects. Serum/seminal plasma Mn levels were inversely correlated with the sperm count (r=-0.279, P=0.02), motility (r=-0.279, P=0.02), and morphology (r=-0.275, P0.04), while Zn levels were positively correlated with sperm motility (r=0.238, P=0.04) and morphology (r=0.258, P<0.03). Eventually, Cu was inversely correlated with motility (r=-0.237, P=0.04) and morphology (r=-0.235, P=0.04). Conclusion: Overall, high levels of Mn in the serum and seminal plasma may have an adverse effect on sperm quantity and quality, and thus, there is a need for routine Mn determination as part of the investigation in the evaluation of infertile males irrespective of the occupation of subjects.
The Relationship of Markers With Carotid Artery Stenosis and Lesion Hardness: Superiority of C-Reactive Protein and Uric Acid
Authors: Yildirim Alp , Celik Mustafa , Kaleli Muhammed Fatih , Keles Fikret , Alpaslan Muhammed , Sokmen Erdogan
Published: July 2023

Background : Atherosclerosis is a disease that cholesterol plaque builds up inside arteries. The process of atherosclerosis starts when certain substances such as cholesterol, fats, and cellular waste products accumulate in the walls of arteries, and the immune system responds to these substances, triggering inflammation. Over time, this inflammation can cause the plaque to grow and harden, narrowing the artery and reducing blood flow. Carotid artery disease (CAD) is a conclusion of plaques in carotid artery. CAD can increase the risk of stroke, a potentially life-threatening condition that occurs when blood flow to the brain is interrupted. Objectives: The objectives of this study were to detect the association between carotid artery stenosis and inflammatory markers. Methods: This study was designed prospectively and included 109 and 100 patients having mild carotid stenosis and severe carotid stenosis, respectively. Further, 101 patients were included in the control group. The carotid ultrasonography was evaluated in all patients. After classifying the plaques into<60% (mild stenosis) and 60%>(severe stenosis) categories, they were also grouped into echogenicity plaques, namely, echolucent (soft) and echogenic (hard) plaques. Results: The uric acid (UA) values of the mild and severe stenosis groups were higher than that of the control group (P<0.01). The mean C-reactive protein (CRP) value was the highest in the severe stenosis group, and the lowest CRP value was found in the control group (P<0.01). A one-unit increase in UA could increase the risk by 2.203 times. The CRP value was higher in the soft lesion group without calcification than in the hard lesion group with calcification. Conclusion: Our findings demonstrated that age, UA, and CRP values were identified as predictors independent of each other in the development of carotid stenosis. Regarding plaque classification, our results identified CRP, mean platelet volume (MPV), white blood cell, and lymphocyte values as negative predictors. The findings of our study indicate that CRP and UA are valuable in predicting the severity of stenosis and the formation of soft plaque.

Background: Gender-based violence (GBV) has been shown to have significant and long-lasting impacts on women’s physical and mental health. It is, therefore, important to study its occurrence in a population and its intersect with infectious diseases such as HIV to inform the wider health promotion agenda. This study aimed to determine the association between GBV and HIV status in women and adolescent girls in Zimbabwe. Methods: A secondary data analysis of data from a cross-sectional Zimbabwe Demographic and Health Survey (ZDHS) was conducted. Statistical analysis was employed to establish the association between GBV and HIV status. Geospatial mapping was conducted using a kernel smoothing method was employed to generate a continuous kernel density surface to illustrate the local spatial variations of female HIV and GBV prevalence. Results: Women and adolescent girls suffering emotional GBV, such as those subjected to humiliation by their husbands or partners, were 1.45 (1.14-1.84) [OR (95% CIs)] times more likely to be HIV positive than those who were never humiliated. The same was true for women and adolescent girls whose husbands or partners threatened to harm them or someone they love, 1.33 (1.04-1.68). There is a relationship between women’s HIV status and intimate partner aggression, such as when their partners pushed, shook, or threw something at them or physically abused them. This was also the case for those who reported that partners kicked, dragged, or beat them, tried to choke or burn them on purpose, or threatened or attacked them with a knife, gun, or other weapons. Women who experienced forced sexual violence with threats were more likely 1.61 (1.08-2.41), to be HIV positive than those women who did not experience the same. Conclusion: GBV is widely spread in Zimbabwe. There is a need for the government to implement creative strategies to reach out to survivors, especially those that are forced to have unprotected sex and are at increased risk of HIV acquisition. This manuscript raises issues that can be addressed by robust health promotion strategies to reduce the impact of the syndemic of GBV and HIV acquisition in Zimbabwe.

Published: July 2023

Introduction: Cardiac complications are the leading cause of death in thalassemia patients. It is assumed that progressive iron accumulation results in myocyte damage. Myocardial T2* measurement by cardiac MRI quantifies iron overload. We aimed to study the association between left and right ventricular (LV and RV) function and iron deposition estimation by cardiac MRI T2* in a sample of Iranian patients. Methods: Cardiac MRI exams of 118 transfusion-dependent thalassemia major patients were evaluated retrospectively. Biventricular function and volume and myocardial and liver T2* values were measured. The demographic and lab data were registered. Poisson and chi-square regression analyses investigated the correlation between the T2* value and ventricular dysfunction. Results: The study participants’ mean (SD) age was 32.7y (9.02), and 47.46% were female. Forty-nine cases (41.52%) revealed at least uni-ventricular dysfunction. LV dysfunction was noted in 20 cases, whereas 47 patients revealed RV dysfunction. The risk of LV dysfunction was 5.3-fold higher in patients with cardiac T2* value less than 10msec (RR=5.3, 95% CI=1.6, 17.1, P<0.05). No association was found between age, liver T2* value, serum ferritin level, and chelation therapy with the risk of LV and RV dysfunction. Conclusion: Cardiac MRI T2* measure is a good indicator of LV dysfunction. Moreover, MRI parameters, especially RV functional measures, may have a substantial role in patient management. Therefore, cardiac MRI should be included in beta-thalassemia patients’ management strategies.
Infective Endocarditis as a complication of COVID-19 infection; A case report and review of literature
Authors: Mohammadi Khadije , Soltani Parya , Davari Nazanin
Published: July 2023

COVID-19 has been known to induce systemic inflammation and hyper coagulate state leading to different complications. Cardiovascular complications are one of the most important among complications following COVID-19 infection. A 57 years old woman with past medical history of COVID-19 infection about two months ago came to our hospital with presentation of fever and dyspnea. During workup, tricuspid valve infection associated with pulmonary septic emboli was diagnosed without any obvious risk factor for infective endocarditis. It seems that COVID-19 infection may increase the rate of endocarditis in patients with or without risk factors of endocarditis.

Published: July 2023

Introduction: Complex electrophysiologic (EP) procedures are time consuming and open to complications. Accurate and rapid recognition of cardiac pathologies is essential before, during, and immediately after such procedures. In this study, we aimed to compare hand-held echocardiography (HHE) with standard echocardiography (SE) to determine whether HHE can be used as a practical and reliable diagnostic tool during such procedures. Methods: One hundred consecutive patients undergoing complex EP procedures and catheter ablation were included in the study. All patients were evaluated with SE or HHE in terms of main cardiac pathologies at the beginning and immediately after the procedure. The diagnostic accuracy and evaluation time of both methods were compared at the beginning and after the procedure. The agreement between both methods was calculated. Results: At the beginning and after the procedure, opening and evaluation times with HHE were significantly shorter than with SE (P<0.001 for all). There was significant agreement between the two methods in the diagnosis of cardiac pathologies (Agreement was 95% for minimal mild aortic regurgitation (AR), 99% for moderate/ severe AR, 93% for minimal/ mild mitral regurgitation (MR), 95% for moderate/ severe MR, 100% for pericardial effusion, and 100% for left ventricular thrombus at the beginning of the procedure). Conclusion: With the use of HHE during complex EP procedures, cardiac pathologies can be diagnosed with similar accuracy as SE. In addition, HHE has a significant advantage over SE in terms of time to diagnosis.

Authors: Shetabi Hamidreza , Nazemroaya Behzad , Mahjobipoor Hosein , Majidi Sanaz
Published: July 2023

Introduction: Providing a stable hemodynamic in extubation is important. We aimed to compare the effect of two different doses of intravenous labetalol on the cardiovascular response to endotracheal extubation. Methods: This double-blind randomized trial was performed in 2019-2020 in Isfahan on 72 patients under general anesthesia. Patients using Random Allocation software were divided into three groups and received 0.1 mg/ kg or 0.2 mg/kg labetalol and normal saline intravenously 10 min before extubation. Hemodynamic variables including heart rate (HR), Systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP), and peripheral blood oxygen saturation(SPO2) was measured for each patient before induction of anesthesia and 1, 3, 5 and 10 minutes after extubation. Results: SBP changes were significantly different between the three groups at 1, 3, 5 minutes after extubation (P=0.036, P=0.009, P=0.005 respectively) unlike the other two groups, patients who received 0.2 mg/kg labetalol did not have an increase in DBP after extubation (P>0.05). DBP was significantly different between the three groups one minute after extubation (P=0.03). At minutes 1 and 3 following extubation, there was a significant difference in the MAP between the three groups. (P=0.029 and P=0.012 respectively). There was no significant difference between the three groups regarding heart rate (P>0.05). Conclusion: Tracheal extubation is usually associated with an increase in hemodynamic variables. Both doses of labetalol attenuate the hemodynamic response accompanying tracheal extubation. But labetalol 0.2 mg/kg in reducing hemodynamic response to extubation acted more effectively than labetalol 0.1mg/kg.

Published: July 2023

Introduction: Acute aortic dissection type A is a life-threatening cardiovascular emergency necessitating rapid diagnosis and treatment. We sought a new prognostic tool with cardiac biomarkers and simple inflammatory factors. Methods: from 2003 to 2014, 50 patients with documented acute aortic dissection type A were entered to this study. These patients were followed up until December 2020; within median follow up of 93.6 months. The patients were evaluated on the association of the baseline characteristics, first laboratory investigation, echocardiographic findings, surgical approach, and long-term mortality. Results: Total number of mortality during the follow up was 29 (58%) patients, which was significantly higher in medical group (89.4% vs 38.7%, P value=0.001). Multivariable analysis showed only an increase in hs-cTnT levels was suggested as a predictor of mortality (95% CI: 1.06–1.38; HR=1.21; P=0.005), so that for every 100 units increase, patients were 21% more likely to have mortality in long term. Also, performing surgical treatment for aortic dissection was determined as the independent predictor of surviving, so that death was 74.6% less than those who received medical treatment (95% CI: 0.13–0.58; HR=0.27; P=0.001). Conclusion: hs-cTnT is a potential predictor of mortality in patients with acute aortic dissection type A.

Authors: Shetabi Hamidreza , Karimian Shima
Published: July 2023

Introduction: Extubation can be associated with an adverse hemodynamic or respiratory response, which may be serious in cardiovascular written or in the elderly. The present study was conducted with the aim of investigating the effect of two different doses of dexmedetomidine in the prevention of extubation complications. Methods: This randomized clinical trial was conducted in Isfahan in 2020-2021 on 174 patients undergoing elective surgery. Patients were randomly divided into 3 groups receiving dexmedetomidine 1 μg/kg (D1), dexmedetomidine 0.5 μg/kg (D2), and normal saline (S). Hemodynamic variables include heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP), and peripheral blood oxygen saturation (Spo2) was measured and recorded before removing the endotracheal tube and at 1, 3, 5 and 10 minutes after extubation. Also, airway responses to extubation such as cough, hoarseness, and laryngospasm were investigated. Results: SBP, MAP, and HR in the D1 group were significantly lower than in other groups. In the D2 group, these measurements were lower than the control group at 3, 5, and 10 minutes after extubation (P<0.05 for all). In placebo group, SBP, MAP, and HR increased significantly after extubation (P=0.01). In group D1, cough (P=0.007) and its intensity (P=0.013), nausea and vomiting (P=0.04) and chills (P=0.001) were less than in other groups. Conclusion: In the D1 group, attenuation of autonomic response to extubation was more than other groups and side effects were less than D2 group, and in both groups, these side effects were less than the saline group.

Three-dimensional (3D) myocardial tissues for studying human heart biology, physiology and pharmacology have recently received lots of attention. Organoids as 3D mini-organs are created from multiple cell types (i.e. induced pluripotent stem cells (iPSCs) or embryonic stem cells (ESCs)) with other supporting co-cultured cells such as endothelial cells or fibroblasts. Cardiac organoid culture technologies are bringing about significant advances in organ research and allows for the establishment of tissue regeneration and disease modeling. The present review provides an overview of the recent advances in human cardiac organoid platforms in disease biology and for cardiovascular regenerative medicine.

Authors: OKUBANJO Ayodeji , OFUALAGBA Godswill , OSHEVİRE Patrick
Published: July 2023

The over-reliance on fossil resources necessitates the development of a sustainable energy system. Renewable energy and efficient hybrid water heating technologies are viable net-zero energy options. The economic benefits of these hybrid technologies offer a promising prospect for widespread adoption in developing countries as a means of increasing the hot water production. These hybrid technologies are becoming increasingly popular for domestic thermal applications in remote areas to compensate for energy shortages. This paper provides an overview of hybrid renewable water heating technologies with a focus on hybrid configurations, optimization techniques, mono-particle, and hybrid nanofluids and modelling. This paper also highlights the prospects for increasing the economic attractiveness and public acceptance of such systems.
Interações entre a pesquisa e as práticas musicais em uma Orquestra de Câmara na Amazônia
Authors: Duarte Fernando Lacerda Simões
Published: July 2023

Este relato de experiência docente procura analisar como a pesquisa musicológica pode servir à aprendizagem de música e à transmissão de novos conhecimentos acerca da música e da memória local ao público em geral. Parte-se da atuação de uma orquestra de câmara estruturada no âmbito do ensino técnico de nível médio em uma instituição localizada na Amazônia. A análise se baseia na noção de cânone musical, presente em Carl Dahlhaus, e na sua desconstrução nos processos de ensino, nas relações entre memória e identidade coletivas, em Joël Candau, bem como na presença da pesquisa no processo de ensino e aprendizagem, a partir do trabalho de Pedro Demo. A relação entre memória e música, neste caso, perpassa a pesquisa arquvística in loco, mas também a audição do repertório praticado em âmbito religioso no presente, a transcrição e a edição do repertório localizado, seu ensaio, performance e outras atividades de difusão da pesquisa por meio da atividade artística tais como explicações dirigidas ao público e notas em programas de concerto. Os resultados apontam para o êxito no engajamento da pesquisa dos participantes da orquestra, mas também os resultados favoráveis do incremento da pesquisa para a própria instituição de ensino.
Um estudo investigativo sobre a evasão dos estudantes no projeto Vale Música
Authors: Toledo Monalisa , Dos Santos Ana Roseli Paes
Published: July 2023

Buscamos, neste trabalho, refletir sobre os fatores que levam jovens e crianças do projeto Vale Música ao insucesso, culminando com o abandono das atividades de aprendizagem musical. O estudo está em desenvolvimento no programa de pós-graduação em música da Universidade Federal de São João Del Rei. A pesquisa é de cunho qualitativo e se desenvolve em um estudo de caso cujos dados foram recolhidos por meio de observação participativa nos ensaios de orquestra, nas aulas de instrumento e de entrevistas semiestruturadas feitas com a coordenadora do projeto, os maestros e professores, alunos e os seus pais. Os resultados preliminares mostram que o não suporte familiar pode contribuir para o abandono da aprendizagem de música em projetos sociais.
Processos de ensino coletivo de violão praticados pela Escola de Música D`alva Stella Nogueira Freire durante o período remoto
Authors: Da Silva José Roberto , Oliveira Gleisson
Published: July 2023

Entre os anos de 2020 e 2022, o mundo foi impactado pela pandemia de COVID-19. Uma condição que demandou um prolongado tempo de isolamento social e, com isso, uma interrupção dos tradicionais formatos de ensino presenciais. Consequentemente, novas modalidades tiveram que ser desenvolvidas para que as instituições de ensino conseguissem manter suas atividades. Neste sentido, esta pesquisa teve como objetivo refletir acerca dos processos de ensino coletivo de violão praticados pela Escola de Música D'alva Stella Nogueira Freire durante o período remoto. Para tanto, foi realizada uma entrevista semiestruturada com um professor da referida instituição, responsável pelas aulas remotas de violão coletivo. Os resultados apontam a relevância de determinadas estratégias de ensino e aprendizado, tais como gravação de vídeos para o estudo prévio dos alunos; adoção do formato masterclass; adesão às plataformas virtuais Google Meet e WhatsApp; bem como oferta de suporte ao aluno pós aula. Este trabalho pode ajudar professores de violão, que atuam tanto no formato remoto e/ou virtual, em aulas coletivas, bem como pode contribuir com a tão desafiante adaptação a essa nova realidade de ensino/aprendizado colocada pela pandemia.
As interações sociais nos processos de ensino e aprendizagem durante a pandemia: o caso do Cursinho Tatita
Authors: Ribeiro Marcelo Ferreira , Nassif Silvia Cordeiro
Published: July 2023

Neste trabalho apresentamos uma pesquisa de Iniciação Científica concluída na Universidade Estadual de Campinas que investigou atividades de estágio durante a pandemia em um curso de Licenciatura em Música. Foi realizado um estudo de caso em um cursinho pré-vestibular que oferece aulas de música gratuitas, no sistema de ensino remoto, para alunos de baixa renda, visando a preparação para as Provas de Habilidades Específicas (PHE). As PHE são pré-requisito para o ingresso nos cursos de Música da instituição e exigem conhecimentos musicais teóricos e práticos. O cursinho foi criado e é conduzido integralmente por discentes do curso de Música, tendo se originado a partir de suas próprias dificuldades em relação às provas. Na pesquisa, de natureza qualitativa, foram realizadas entrevistas com 3 estudantes estagiários, a partir das quais foi possível levantar alguns tópicos de discussão. No recorte aqui apresentado focamos na questão das interações sociais, fundamentais em qualquer processo educacional, e que ficaram fragilizadas durante o período de isolamento. Por outro lado, os dados levaram também a perceber as saídas encontradas pelos estudantes/docentes do cursinho para enfrentar as condições adversas que se colocavam, com especial destaque para as práticas colaborativas que foram sendo criadas nos ambientes virtuais.
A Teoria de Aprendizagem Musical de E. Gordon em diálogo com a Psicologia Histórico-Cultural de L. Vigotski: subsídio para a formação de educadoras(es)
Authors: Villalba Juliana Muniz , Nassif Silvia Cordeiro
Published: July 2023

O presente artigo compartilha dados sobre uma oficina de formação continuada para educadoras(es) musicais em uma universidade do estado de São Paulo, oferecida como parte de um projeto de mestrado em andamento nessa mesma universidade. O objetivo da oficina era apresentar, de maneira teórica e prática, conceitos chaves da Teoria de Aprendizagem Musical de Edwin Gordon relacionados ao aprendizado musical na primeira infância. Foi observado que educadoras(es) participantes tiveram a construção da sua própria musicalidade impactada positivamente, além de construírem uma outra perspectiva acerca de práticas pedagógicas musicais na primeira infância. Todos esses resultados foram analisados a partir da Psicologia Histórico-Cultural de Lev Vigotski, demonstrando possíveis pontos de contato entre as teorias.
AmarElo, de Emicida, e O Pequeno Príncipe Preto, de Rodrigo França: a música como primeiro contato literário no ensino de literatura
Authors: Oliveira Santos Walisson , Silva Alba Valéria Niza
Published: July 2023

Este trabalho se propõe a compreender a música como importante recurso didático para a educação de crianças, jovens e adultos. Isso a partir da música “AmarElo”, do compositor e rapper Leandro Roque de Oliveira, o Emicida, em diálogo com o livro infantil O Pequeno Príncipe Preto (2020), de Rodrigo França, este como primeiro contato após a aplicação de textos musicais no ensino de literatura. Posto isso, partimos da hipótese que a música atua na formação dos indivíduos. Esta que envolve o respeito às diferenças, às experiências interpessoais, o que possibilita a construção de seres críticos, capazes de refletir sobre a sua posição no mundo e a sociedade na qual estão inseridos. Além disso, delineamos o seguinte problema: Como a música pode funcionar como interação em sala de aula, de resgate do prazer e motivação na busca do conhecimento e, também, para o ensino de literatura? A partir de nossas análises comparativas, em “AmarElo”, Emicida deixa em aberto o discurso dos excluídos e a reivindicação de espaços culturais fechados no contexto da negritude brasileira; já em O Pequeno Príncipe Preto, de Rodrigo França, o livro permite que a todas as crianças, jovens e adultos, negros ou brancos, entendam que não existe uma cultura universal e passem a valorizar mais a diversidade e a pluralidade.
