Published: July 2023

Polycyclic aromatic oils, high in aromatic content are used in tyre compounds as processing aids and these have been found to be carcinogenic. Therefore, it is necessary to find processing aids consisting of a low content of aromatics which would help to overcome the problem associated with the use of petroleum-based aromatic oils.
The main aim of this research was to develop carbon black filled natural rubber (NR) composites using environmentally friendly sesame oil as the processing aid. Initially sesame oil was characterized using Fourier Transform Infra-Red analysis. Thereafter, a series of NR based tyre tread compounds was prepared by varying the sesame oil loading from 3-9 phr at 2 phr intervals. Cure characteristics, physico-mechanical and swelling properties of these composites were evaluated and compared with those of the composite prepared with the aromatic processing oil, Dutrex-R (control). Dispersibility of carbon black in all the NR composites was assessed.
Viscosity, processing safety and cure rate of the composite produced with 5 phr sesame oil were higher compared to the control and indicated that the oil behaves as a co-activator in rubber compounds. Hardness, modulus at 100% elongation and abrasion volume loss of the vulcanizates prepared with more than 5 phr sesame oil were lower, whereas tensile strength, elongation at break and resilience were higher than those of the control. Tear strength and compression set of the vulcanizates prepared with 5 phr sesame oil were comparable to those of the control. Further, the former vulcanizate showed a higher and lower swelling indices in toluene and water, respectively compared to the control. Furthermore, the vulcanizates prepared with sesame oil showed better ageing resistance in comparison to the control. Hence, sesame oil could be a suitable alternative for Dutrex-R in tyre tread compounds at 5 phr level.

Published: July 2023

The primary aim of this work is to standardize the procedures for the handling, preparation, and distribution phases of food and beverages in collective catering within National Police structures. Therefore, its purpose is to offer aid for the assessment and implementation of procedures regarding the catering services activities carried out in canteens and bars located within the National Police areas. A checklist was elaborated to establish criteria and methods to verify these activities, to assess and enhance the effectiveness of the control system, and subsequently, to enable the implementation of any corrective measure, with the aim of ensuring the consumption of healthy food and preventing the occurrence of food-borne diseases as a result. The study was carried out in 2022 in 6 National Police canteens located in Central Italy and managed by a contractor for the specific service. These structures serve an average of 300 meals daily, divided into 1-3 ordinary meals (breakfast, lunch, and dinner). The examined canteens reported 3 minor non-conformities, 3 major non-conformities, and no critical non-conformities. This report regards the analysis of detected issues and corrective measures concerning catering hygiene in the Police Force to ensure food safety. To date, no guidelines have allegedly been established for the regulation of the procedures for carrying out the periodical mandatory inspection of collective catering operations. The results of this paper showed a well-controlled management of these activities concerning the hygiene and infrastructural aspects of the food chain.
L’ISTITUTO DI FARMACOLOGIA DELL’UNIVERSITà DI MILANO DAL 1946 al 1980
Authors: Clementi Francesco
Published: July 2023

The global pandemic of Covid-19 has caused enormous damage to scientific research by dramatically reducing the functionality of the institutions responsible for it and at the same time polarizing many lines of research toward solving the pandemic problems. This situation has similarities with what happened during the Second World War. In that case, the post-war recovery was intense, also bringing many changes in the methodology and motivations of scientific research. In this paper I analyzed, as a model of post-war rebirth, that of the Institute of Pharmacology of the University of Milan that became from a small laboratory a research and teaching institution based on human and scientific concepts that were innovative at the time. Its birth started in the years 1946-47, was favored by the collaboration between private and public institutions (the De Marchi Foundation, the University of Milan and the Municipality of Milan), was build by the scientists as a high-level, broad-based international study center, and formed the basis of a possible example of a university campus. The methodological and conceptual development of a new pharmacology and its growth in researchers and scientific purposes are outlined. The birth from this Institute of the Mario Negri Research Institute, of the School of Pharmacy of the University of Milan, of the Cellular and Molecular Pharmacology Center of the CNR and of the Lombardy Biomedical Library System is briefly described. The different reactions to a global damage brought to science and research in the post-war and post-pandemic periods are discussed.
Old tricks and new trends to address tumors: a medicinal chemist’s perspective
Authors: Seneci Pierfausto
Published: July 2023

Major efforts in the past decades have provided novel small molecule drugs and biologicals and innovative mechanisms against tumors, but the quest for safer, bioavailable and more effective active principles is still ongoing. This contribution focuses on innovative approaches to fulfill therapeutic goals in oncology; namely, the inhibition of the stabilizing interaction between the RNA-binding protein HuR and mRNAs of multiple oncogenes, and the unleashing of a strong immune reaction against cancer cells by antagonizing the PD-1 – PD-L1 interaction on the surface of cancer cells. “Classical” drug-like, bioavailable small molecules were either rationally designed from a naturally occurring template (tanshinones converted to aza-tanshinones – HuR), or from a synthetic peptidomimetic inhibitor (biphenyloxy aryls converted to disubstituted triazines – PD-L1); after their synthesis and activity profiling, early leads were identified to be further structurally optimized in the near future.
Preceptor Education on the Use of Clinical Teaching Models in Clinical Education
Authors: Graham Jason , Heinerichs Scott , Barnum Mary , Monaco Michele , Martin Malissa , Singe Stephanie M.
Published: July 2023

Context

Preceptor training is designed to provide instruction on preceptorship, an overview of athletic training program processes, and preceptor professional development. Preceptors generally do not have formal training on how to be educators. Most preceptor training occurs at the institutional level, with content, frequency, and delivery at the discretion of the institution.

Objective

Investigate preceptors' perceptions of how preceptor training prepares them for using clinical teaching models and how preceptor training can be improved.

Design

Concurrent mixed methods.

Setting

Web-based survey and virtual semistructured interviews.

Patients or Other Participants

One hundred sixty-five preceptors (average of 10 ± 9 years of preceptorship experience) completed the survey. Ten participants (4 male, 6 female) participated in interviews (average of 12 ± 10 years of preceptor experience).

Data Collection and Analysis

Surveys were dispersed via Qualtrics, and virtual interviews were recorded using Zoom. The χ2 test for independence determined if any relationships existed between years of experience, type of preceptor training, and clinical teaching models used. A phenomenological approach of inquiry was used to analyze the interview data. Trustworthiness was established with member checking, triangulation using 2 data collection methods and independent data analysts, and external peer review.

Results

Participants reported preceptor training focuses on programmatic administration rather than clinical teaching. In our study, 68% of preceptors had completed institutional preceptor training related to clinical teaching, and 24% had completed the Master Preceptor level 1 training program. Preceptors desire training that incorporates active engagement regularly to educate them on clinical teaching models.

Conclusions

The content and frequency of institutional preceptor training should be reassessed, as it provides foundational knowledge to preceptors on clinical teaching. Most preceptors have little formal preparation in clinical teaching and believe preceptor training does not adequately prepare them to educate students using the best clinical teaching practices for the profession.
Echocardiographic findings in infants of diabetic mothers and their relation to maternal glycemic control
Authors: Farag Marwa Mohamed , Marzouk Iman Mohamed , Mohsen Aly Mohamed Abdel , Emara Asmaa Mohamed Ramadan
Published: July 2023

Background

Diabetes mellitus during pregnancy is a common risk factor for both mothers and infants. Prediction of cardiac problems in infants of diabetic mothers is challenging.

Aim

The purpose of the study is to determine the type and incidence of congenital heart diseases in infants whose mothers are diabetic in the NICU of Alexandria university maternity hospital, as well as to evaluate functional and morphological changes in the myocardium and its relationship to maternal glycemic control.

Patients and methods

A case-control study was conducted in the NICU of Alexandria University Hospital. Thirty-five infants of diabetic mothers (IDM) were compared to 37 healthy control infants. All diabetic mothers had their HBA1C levels measured before delivery. Therefore, the infants of diabetic mothers were further divided into 22 infants whose mothers had controlled diabetes (controlled DMM group; controlled diabetes mellitus mothers group) during pregnancy (predelivery HBA1C≤6.5) and 13 infants whose mothers had uncontrolled diabetes during pregnancy (uncontrolled DMM group). All studied infants were scanned for the presence of congenital heart diseases. Right and left ventricular systolic functions were assessed, and septal and left ventricular dimensions were measured using functional echocardiography (FE). Followup scans were done 1–2 months later.

This work was registered on clinical trial.gov NCT05050058

Results

Incidence of congenital heart diseases is significantly increased in infants of diabetic mothers compared to healthy control group with P value =0.008. Intraventricular septal thickness and left ventricular posterior wall during systole and diastole (IVSs, IVSd, LVPWs, LVPWd and IVSd/ LVPWd ratio) significantly increased in IDM group. Patients whose mothers had uncontrolled diabetes had their IVSd and IVSd/ LVPWd ratio markedly increased over the uncontrolled group. After 45–60 days the septal and posterior wall measures during systole and diastole decreased significantly. Tricuspid regurge (TR) gradient is markedly increased in IDM in the first 24 h after birth, specifically in infants with mothers with poor glycemic control during pregnancy.

Conclusion

Infants of diabetic mothers were significantly more likely to suffer from ASD, VSD, and complex heart disease. Complex heart diseases were significantly associated with pregestational maternal diabetes. Infants of diabetic mothers with poor glycemic control have affected IVSd and IVSd/LVPWd ratios. Ventricular septal and LVPW measures were markedly improved after 45–60 days of age .Neither the presence of maternal diabetes nor the diabetic control of mothers affected the right and left ventricular functions of their infants.

Authors: Elmeazawy Rehab , Shoeib Sara
Published: July 2023

Background

Asthma is a multifaceted disease marked by recurrent airway inflammation. The aim of the study is to evaluate the significance of total immunoglobulin E (IgE) in asthmatic children and find the relation of its level to the disease severity

Patients and methods

Forty-five children with acute bronchial asthma aged between 5 and 16 years, and 15 control children with comparable age and sex distribution were included in the study. All children will be subjected to complete blood picture, Total IgE, and spirometry test Forced Expiratory Volume (FEV1), Forced Vital Capacity (FVC), FEV1/FVC.

Results

Among the 45 patients, 57.8% were male, with a median age of 10 years. There were statistically significant differences between the asthmatic groups and the control group as regards sex, weight, total IgE level, FEV1, FVC, and FEV1/FVC ratio. There was a significant positive correlation between IgE level and age, weight and height (r=0.465, P< 0.001, r=0.349, P=0.019, r=0.314, P=0.036, respectively)

Conclusion

Total IgE level was shown to have a role in the diagnosis of asthma and can be used as a predictor of asthma severity in children

Authors: Das Shouvik , Chaudhuri Arunima
Published: July 2023

Background:

During the COVID-19 pandemic, medical students and health-care professionals faced significant challenges, which had a negative impact on their mental health.

Aims:

This study aimed to assess the mental health of male and female undergraduate medical students and the psychological effects of the COVID-19 pandemic.

Participants and the Methodologies:

After receiving institutional ethical clearance and the informed consent of the participants, this study was carried out on 591 medical students from a peripheral medical college in West Bengal during the first and second waves of the COVID-19 pandemic. At intervals of 6 months, two surveys were conducted. The Depression Anxiety and Stress Scale-21 and Impact of Event Scale–Revised scale scores were evaluated in the Google Forms surveys. Using the t-test and the Chi-square test, the parameters of the two groups of students were compared.

Results:

On the initial assessment, neither group received a score that was significantly different from the other. Female students had significantly higher anxiety scores than male students on the second assessment. During the second pandemic wave, there was a significant gender difference in anxiety and stress levels (P = 0.001), with females experiencing higher levels of anxiety and stress.

Conclusions:

During the second wave of the COVID-19 pandemic, female undergraduate medical students had higher stress and anxiety levels than their male counterparts, according to the current study. Therefore, it is possible to draw the conclusion that the spread of the pandemic had a greater negative impact on the mental health of female undergraduate students.

Authors: Pustake Manas , Giri Purushottam , Ganiyani Mohammad Arfat , Mumtaz Kahkashan , Deshmukh Krishna , Saju Michael , Nunez Judith Vasquez , Orlova Natalia , Das Arghadip
Published: July 2023

Background:

Since November 2019, when the novel coronavirus arose in Wuhan City, over 188 million people worldwide have been infected with COVID-19. It is the third coronavirus outbreak in the twenty-first century. Until now, practically all coronavirus epidemics have occurred due to zoonotic spread from an animal or transitional host or through the consumption of their products. Coronaviruses can infect humans and cause severe illness and even death.

Material and Methods:

This review was designed to help us recognize and harmonize the similarities and differences between these three coronaviridae family members.

Result:

Measures aimed at containing the epidemic should be emphasized in this circumstance. Prioritizing and planning these activities require an understanding of the particulars of these three viruses. Given the pandemic’s enormous death toll and rapid spread, we should be cognizant of the parallels and differences between these three viruses. Additionally, this pandemic warns us to be cautious against the possibility of a future pandemic.

Conclusion:

We highlight the fundamental characteristics of coronaviruses that are critical for recognizing coronavirus epidemiology, pathogenesis, and pathological features that reveal numerous significant pathological attributes and evolutionary patterns in the viral genome that aid in better understanding and anticipating future epidemics.
Why do Mothers from Remote Rural Areas opt for Cesarean Delivery: An Observational Analytical Study from West Bengal, India
Authors: Ahamed Farhad , Rehman Tanveer , Kaur Amandeep
Published: July 2023

Background:

The percentage of cesarean section (C-section) deliveries has doubled in the last two decades in India. Although C-section delivery is a life-saving intervention, multiple maternal and neonatal morbidities are often associated with this procedure, adversely affecting the quality of life of both the mother and child.

Material and Methods:

This community-based cross-sectional study was conducted to assess the point of view of mothers who delivered from January 2020 to June 2021.

Results:

The mean (standard deviation (SD)) age of the 866 study participants at delivery was 24.5 (4.8) years, and 60.2% were primigravidas. A total of 613 (70.8%; 95% CI: 67.8–73.8) C-sections were conducted, of which 65.9% (n = 404) were planned and 21.9% were done on maternal request. C-sections were significantly associated with private institutes (adjusted prevalence ratio (aPR) 1.90; 95% CI: 1.70–2.11), at-risk pregnancy (aPR 1.37; 95% CI: 1.26–1.49), and primigravida (aPR 1.16; 95% CI: 1.05–1.29). About 55.3%, 29.8%, and 14.9% of women considered vaginal delivery to be risky, painful, and inconvenient, respectively.

Conclusion:

It is imperative to generate awareness regarding modes of delivery during antenatal care (ANC) so that mothers can make better-informed choices.

Authors: Ghosh Abhishek , Mahintamani Tathagata , Aswathy P. V. , Basu Debasish , Mattoo Surendra K. , Subodh B. N. , Pillai Renjith R. , Kaur Manpreet
Published: July 2023

Aim:

We aimed to assess the service user’s acceptability, feasibility, and attitude toward telemedicine practice and compare it with in-person consultation in substance use disorder (SUD).

Materials and Methods:

We recruited 15 adult patients with SUD who accessed both telemedicine and in-person care. We conducted in-depth interviews on awareness and access, facilitators and barriers, treatment satisfaction, and therapeutic relationship in the telemedicine context. We performed a conventional content analysis of the interview excerpts and used inductive and deductive coding. We assumed that social, personal, and logistic contexts influence patients’ perceptions and experiences with telemedicine-based addiction care (TAC).

Results:

Most participants were middle-aged men (40.5 years, 86.7%), dependent on two or more substances (86.7%), and had a history of chronic, heavy substance use (use ~16 years, dependence ~11.5 years). Patients’ perspectives on TAC could broadly be divided into three phases: pre-consultation, consultation, and post-consultation. Patients felt that TAC improved treatment access with adequate autonomy and control; however, there were technical challenges. Patients expressed privacy concerns and feared experiencing stigma during teleconsultation. They reported missing the elaborate inquiry, physical examination, and ritual of visiting their doctors in person. Additionally, personal comfort and technical difficulties determine the satisfaction level with TAC. Overall perception and suitability of TAC and the decision to continue it developed in the post-consultation phase.

Conclusion:

Our study provides an in-depth insight into the barriers and facilitators of telemedicine-based SUD treatment access, use, and retention; it also helps to understand better the choices and preferences for telehealth care vis-à-vis standard in-person care for SUDs.
Factor structure of the Jefferson Scale for Empathy among medical undergraduates from South India
Authors: Praharaj Samir Kumar , Salagre Santosh , Venkata Narasimha Sharma Podila Sathya
Published: July 2023

Background:

Empathy is a multidimensional construct and is considered an essential attribute among healthcare professionals. The Jefferson Scale for Empathy (JSE) is a commonly used tool to measure physician empathy and has been used in medical students as well; however, the psychometric properties have not been well studied in India. We aimed to study the factor structure of JSE among medical undergraduates.

Methods:

This was a secondary analysis of baseline data obtained from the Stigma, Empathy and Attitude module study among medical undergraduates (N = 157). The scores obtained on the 20-item JSE Medical Student Version were subjected to principal component analysis with varimax rotation. Eigenvalues greater than unity, scree plot, and Horn’s parallel analysis were used for identifying the factors. Items with loading more than 0.4 were included based on Steven’s recommendation.

Results:

The sample was adequate for factor analysis (Kaiser–Meyer–Olkin (KMO) measure 0.832). Five factors were extracted using principal component analysis, which explained 60% of the variance. The first three appeared as stable factors, and the last two factors had two items each. The first factor was the strongest (explained 18.8% of variance) with loadings from nine items. The second factor (explained 15.6% of variance) had loadings from six items, and two of the items showed correlation with the first factor.

Conclusions:

JSE has a multidimensional structure with five factors in our sample of medical undergraduates.
Multimorbidity clusters and associated health care cost among patients attending psychiatric clinics in Odisha, India
Authors: Gupta Priti , Cunningham Solveig A. , Ali Mohammed K. , Mohan Sailesh , Mahapatra Pranab , Pati Sanghamitra C.
Published: July 2023

Introduction:

There is a dearth of data on common multimorbidity clusters and the healthcare costs for individuals with mental health disorders. This study aimed to identify clinically meaningful physical-mental multimorbidity clusters, frequently occurring clusters of conditions, and healthcare utilization patterns and expenditure among patients attending a psychiatric outpatient clinic.

Materials and Methods:

Data were collected in the psychiatric outpatient department among patients aged 18 years and above in February-July 2019 (n = 500); follow-up data on non-communicable disease incidence were collected after 18 months. For analysis, morbidity clusters were defined using two approaches: 1) agglomerative hierarchical clustering method to identify clusters of diseases; and 2) non-hierarchical cluster k mean analysis to identify clusters of patients. Self-reported healthcare costs in these clusters were also calculated.

Result:

Two disease clusters were identified: using the 1st approach were; 1) hypertension, diabetes, and mood disorder; 2) Neurotic, stress-related, and somatoform disorders, and acid peptic disease. Three clusters of patients identified using the 2nd approach were identified: 1) those with mood disorders and cardiometabolic, musculoskeletal, and thyroid diseases; 2) those with neurotic, substance use, and organic mental disorders, cancer, and epilepsy; and 3) those with Schizophrenia. Patients in Cluster 1 were taking more than six medicines and had more hospital visits. Within 18 months, 41 participants developed either one or two chronic conditions, most commonly diabetes, hypertension, or thyroid disease.

Conclusion:

Cardiometabolic diseases are most commonly clustered with mood disorders. There is a need for blood pressure and sugar measurement in psychiatric clinics and mood disorder screening in cardiac, endocrinology, and primary care clinics.

Authors: Dhiman Kartar Singh , Kumar Manoj , Mukhopadhyay B. , Gupta Kiran
Published: July 2023

This report presents a challenging case of a young adult, who was preparing to join Indian forces. The management strategy involved the use of anti-inflammatory drugs with formulations having properties of Vata (~Dosha responsible for movement and cognition) regulation. The results were recorded in the changes in the Lateral Rectus (LR) muscle functioning and also in visual symptoms, i.e., diplopia after the treatment. The outcomes establish the importance of Vata in controlling movements and its regulation in the treatment of disorders related to imbalance or aggravation of Vata. The LR muscle palsy although not rare, its cause, in this case, happens to be uncommon and difficult to attribute. This case gives a better understanding of the management of eye manifestations through Ayurveda.

Are Graphic Designers Killing Newspapers?
Authors: Barnhurst Kevin G.
Published: July 2023

El periódico está condenado a muerte, según pronósticos recientes, y en su lugar surgirá otra forma de periodismo tecnológico. Hasta los directores de prensa han dicho que han de dejar el negocio de fabricar periódicos a favor de fabricar la información. Esta manera de pensar quita del periodismo una pasión por la tinta y el papel, materiales que dieron forma a la prensa. También quita el futuro de periodismo de las manos de periodistas y lo deja en manos de otros, los especialistas en la informática y en la confección, cosa necesaria cuando las noticias se convierten en algo tan árido como información. Diseñadores son artistas con valores ajenos al periodismo. Los tipógrafos honran el libro sobre todo y se esfuerzan para dar al periódico una pinta que parece más al libro. Ilustradores tienen el afán de convertir la página de prensa en un poster como los de Toulouse-Lautrec. Los que diseñan la infografía admiran a Minard y los diagramadores emulan a Mondrian. Las consecuencias son visibles en páginas que son una belleza, pero carecen de noticias acerca de la vida ordinaria. Sin espacio para un público más diverso, el periódico sí tiene que morir. La tinta y el papel son las claves del ritual de leer la prensa. Noticias en papel contribuyen a la memoria colectiva de una manera en la cual las formas digitales no pueden, por lo menos hasta ahora.

A data science and machine learning approach to continuous analysis of Shakespeare's plays
Authors: Swisher Charles , Shamir Lior
Published: July 2023

The availability of quantitative text analysis methods has provided new ways
of analyzing literature in a manner that was not available in the
pre-information era. Here we apply comprehensive machine learning analysis to
the work of William Shakespeare. The analysis shows clear changes in the style
of writing over time, with the most significant changes in the sentence length,
frequency of adjectives and adverbs, and the sentiments expressed in the text.
Applying machine learning to make a stylometric prediction of the year of the
play shows a Pearson correlation of 0.71 between the actual and predicted year,
indicating that Shakespeare's writing style as reflected by the quantitative
measurements changed over time. Additionally, it shows that the stylometrics of
some of the plays is more similar to plays written either before or after the
year they were written. For instance, Romeo and Juliet is dated 1596, but is
more similar in stylometrics to plays written by Shakespeare after 1600. The
source code for the analysis is available for free download.

Iman dan Pertobatan: Konten Pendampingan Pastoral bagi Jemaat Menjelang Kematian Akibat Penyakit Kronis
Authors: Nanda Sianturi Dwi Arya , Dharmawan Kustiadewa Ananda , Panjaitan Firman
Published: July 2023

Pendampingan pastoral sangat dibutuhkan, khususnya bagi seorang penderita penyakit kronis. Melalui pendampingan pastoral tersebut, penderita penyakit kronis akan dipersiapkan untuk menghadapi kematian, baik secara jasmani maupun rohani. Namun yang lebih penting dari itu, pendampingan pastoral terhadap penderita penyakit kronis akan memberikan kepastian bahwa keselamatan dari Yesus akan diberikan kepada penderita jika mereka berkenan untuk mengakui dosa dan bertobat. Melalui metode kualitatif-deskriptif guna mendapatkan data faktual secara konseptual, penelitian ini menghasilkan temuan bahwa pendampingan pastoral terhadap orang yang sedang mengalami sakit kronis harus dilakukan dengan mengajak penderita untuk terlebih dahulu mengakui segala dosa yang telah mereka lakukan akibat ketidakmampuan mereka dalam mengasihi diri mereka.

A Droplet of Liquid Steel: Prills in Crucible Steel Production Remains
Authors: Desai Meghna , Rehren Thilo
Published: July 2023

The formation of steel prills is evident from all crucible steel production ceramics. The paucity of crucible steel ingots in the archaeological record means that the full production chaîne opératoire remains incompletely known and partly speculative. Here, we use the analysis of prills from crucible slags and crucibles to explore the composition of the missing ingots and to learn more about  their formation conditions. To test the correlation of prill compositions with the ingots and/or the crucible ceramic, we examined prills  formed in two different crucible types - ferruginous and non-ferruginous, used in Telangana (India) and Merv (Turkmenistan) crucible steel production, respectively. Both crucible types, when fired at high temperatures under reducing conditions, form prills across the  crucible profile, i.e. in the outer fuel ash glaze, the crucible body and the inner crucible slag. Ferruginous crucibles from Telangana  showed abundant, pronounced and relatively large prills as compared to the iron-poor kaolinitic crucibles of Merv. Factors including the clay selection and addition of various tempers, fuel ash and crucible charge all showed an influence on the prill composition. Using  SEM-EDS as our analytical tool, we discuss the factors that influence the alloying elements in prills, the prill microenvironments and  their potential relationship to the corresponding ingots.

Para contribuir al entendimiento del emprendimiento femenino a nivel nacional, se identificaron las características de las empresas, estilos de liderazgo, gestión empresarial y las principales barreras a las que se enfrentan las mujeres emprendedoras en el sector turístico de Sonora, considerando las 4 dimensiones de la teoría de Gibb Dyer (1993) sobre la carrera empresarial. Se encuestaron a 33 empresarias sonorenses, encontrando que sus características y las de sus empresas están relacionadas con su desempeño. Las emprendedoras han encontrado en el sector turismo una excelente oportunidad para emprender, sin descuidar sus otros roles, como ser madre y esposa. Así mismo, se puede concluir que los factores personales presentan ventajas competitivas y de oportunidad para el emprendimiento, como son sus altos niveles de escolaridad, la edad (de 30 a 50 años), y que cuentan con el apoyo y valoración por parte de su familia. El empoderamiento mostrado por las emprendedoras se evidencia en su participación como principales tomadoras de decisiones dentro de sus empresas, esto puede dotarlas de poder e inspirar a otras mujeres a asumir un rol más dinámico en su búsqueda de oportunidades en negocios dentro del turismo. Es relevante destacar la contribución de esta investigación a un campo poco estudiado como es el de las emprendedoras en el sector turismo, dados sus aportes a la reducción de la pobreza, y al logro de los Objetivos de Desarrollo Sostenible (ODS), especialmente a los ODS 1 (Fin a la pobreza), 5 (Lograr la igualdad entre los géneros y empoderar a todas las mujeres y las niñas) y 8 (Promover el crecimiento económico inclusivo y sostenible, el empleo y el trabajo decente para todos).

Es importante reconocer que, en muchas pymes, el trabajo contable y tributario es realizado por una sola persona que puede tener o no tener experiencia o la capacitación adecuada para cumplir con estas responsabilidades de manera eficiente y efectiva. El trabajo de investigación va a analizar las necesidades de perfiles profesiones en el ámbito contable y tributario en las pymes del cantón La Maná. La muestra estudiada perteneció a 191 pymes constituidas en el cantón La Maná. Para ello, se utilizó un enfoque cuantitativo, con un alcance correlacional porque se relacionaron ambas variables y se aplicó un método de análisis factorial exploratorio. Los resultados arrojaron que existió correlación únicamente el cinco de seis factores establecidos dando un porcentaje acumulado del 83%. Finalmente, se concluyó que, los dueños o gerentes de las pymes deben optar por la contratación de personal capacitado para realizar sus procedimientos contables y tributarios porque puede ayudar a mantener los antecedentes financieros de la organización en orden y actualizados, cumpliendo con las obligaciones tributarias y evitar problemas incluyendo fraudes que puede ser una pérdida exponencial para las pymes.
A construção de uma sequência didática on-line sobre a reprodução e dispersão do Pinheiro-do-Paraná Araucaria Angustifolia (Bertol.) Kuntze
Authors: Lisbôa Eliana Santana
Published: July 2023

Por muitas vezes, o ensino relacionado na área da Botânica é trabalhado de maneira pouco significativa com os alunos, podendo causar prejuízos na aprendizagem. Isso ocorre, pois, alunos e professores acreditam que os termos da Botânica são complexos, relacionando-os apenas para fins paisagísticos. Portanto, o trabalho tem como finalidade desenvolver e validar uma Sequência Didática On-line, baseada na estratégia Hands-On-Tec, para auxiliar professores e alunos no processo de ensino e aprendizagem acerca da reprodução e dispersão do Pinheiro-do-Paraná. Em termos metodológicos, o estudo qualitativo foi baseado na Design-Based Research (DBR). A partir da análise de dados, pode-se perceber que os conteúdos e materiais auxiliam os professores na contextualização do tema, podendo ser potencialmente aplicada na educação básica e superior.

Authors: Bezerra Hanna Patrícia da Silva , Alves José Moysés
Published: July 2023

Considerando a importância da Biologia no ensino médio, realizamos uma revisão do tipo estado da arte com o objetivo de identificar como as dificuldades de aprendizagem e sua superação são apresentadas em pesquisas de natureza interventiva sobre o ensino de Biologia. Analisamos 56 pesquisas, no período de 2010 a 2020. Evidenciamos a utilização de referenciais teóricos variados, em pesquisas com abordagem qualitativa. As dificuldades de aprendizagem não foram objeto de estudo específico, sendo consideradas nas justificativas das pesquisas e atribuídas à complexidade do conteúdo, às características dos aprendizes e às metodologias de ensino. Identificamos intervenções pedagógicas diversificadas, em geral, avaliadas como bem sucedidas. As pesquisas enfatizaram a dimensão operacional da aprendizagem e poucos trabalhos consideraram a singularidade dos estudantes e suas relações afetivas.
