Health and education policies aimed at children, adolescents and adults in the Brazilian public school system join forces in the attempt to promote health and comprehensive education, aiming to address the vulnerabilities that threaten the satisfactory development of these social subjects. Thus, the PSE is translated into a strategy of integration between health and education, with a view to shaping citizenship and improving existing public policies in Brazil. This is an experience report on a vaccination activity carried out in a state educational institution in Rio Grande do Norte. The activity was conducted by a nursing team, nursing interns and some Community Health Agents (CHA), providing the following vaccines: MMR, adult diphtheria and tetanus (dT), Hepatitis B and Influenza. The aim was to promote the availability of up-to-date vaccinations for individuals attending the public school in question. The administration of 80 doses of vaccines was provided, in general, to students and employees of the educational institution, who had pending issues of the respective immunobiologicals on their vaccine cards. Therefore, the importance of this action of the PSE is reaffirmed by enabling greater approximations with this public, which often ends up distancing themselves from the services offered at the UBS. In addition, the University presents itself as an integration component in the PSE, so that it offers students who are readily qualified to add to the health workforce.

Female protagonism and organic management of productive backyards: Instagram as a tool for disseminating the implementation of the sustainable development goals of the 2030 agenda
Authors: Caminhas Ana Margarida Theodoro , Gomes Gabriel Henrique da Silva
Published: January 2024

The United Nations 2030 Agenda is a plan to achieve a better world for all peoples and nations by 2030. This document was consolidated at the United Nations General Assembly in September 2015, in which 193 countries, including Brazil, established 17 sustainable development goals. In addition, Sustainable Development Goals (SDGs) 1 (eradication of poverty), 2 (zero hunger and sustainable agriculture), 3 (health and well-being), 5 (gender equality), 10 (reduction of inequalities), 11 (sustainable cities and communities), 13 (action against global climate change), 14 (life below water) and 15 (life on land) relate to productive backyards of family farming, due to the strengthening of sustainability and female protagonism, and SDG 4 (quality education), which was achieved according to the proposed activities, promoted an interaction between the Affirmative Actions for Diversity and Inclusion team (which receive support from the Dean of FCAV/Unesp) and the women farmers of the settlement of Córrego Rico (SP), capable of generating an exchange of knowledge for both. However, there is still a lack of access to information on this subject by the population. Therefore, social networks such as Instagram can help in the dissemination of this knowledge, so with this work we seek to apply it in posts about Family Farming, Female Protagonism, Agroecology and Productive Backyards, based on interviews with family farmers from the Association of Family Women Farmers of the Córrego Rico Settlement (A.M.A.A.R.) who are responsible for the management of productive backyards and were also consulted scientific articles and extracted pertinent information in an accessible language on these topics. Subsequently, the metrics of the posts (likes, comments, shares and saves) and the opinion of the followers were analyzed through the answers of a questionnaire that was created through Google Forms, to evaluate the contribution of the posts of the @amaar_projeto profile on Instagram, in which the content of these publications relates the daily life in the productive backyards of family farmers with the fulfillment of the objectives of the 2030 Agenda. Through the questions on the form, it was found that a large part of the respondents consider as "very important" the actions that A.M.A.A.R family farmers do in their productive backyards for the fulfillment of the proposed SDGs. Therefore, Instagram has proven to be an excellent tool to scientifically disseminate that the productive backyards of family farming contribute to the fulfillment of the Sustainable Development Goals of the 2030 Agenda, due to the female protagonism and the sustainable agroecological management that occurs in them.

IDENTIFICATION OF DAMAGE IN STEEL BEAM BY NATURAL FREQUENCY USING XGB MODEL
Authors:   Le Quy Don Technical University, Hanoi, Vietnam, Vu Van Tuan
Published: January 2024

Beams have played a significant role in engineering applications and they have been commonly used for modelling civil problems. Different models and methods have been developed to identify the damage to the beams. In this article, the extreme gradient boosting (XGB) model was developed to predict the location, width and depth of the saw-cut of steel beams by the change of natural frequencies. The natural frequencies of a steel beam in different scenarios were identified by the finite element method (FEM). The criterions to evaluate the accuracy of the models were the R squared (RSQ) and the mean square error (MSE). The result indicated that combining the FEM method with XGB would hold significant potential for applications in structural health monitoring.
RESEARCH THE INFLUENCE OF STIFFNESS OF BEAM ON THE FORCE TRANSMISSION TO THE PONTOON AND ON THE MOMENT IN THE BEAM DUE TO CONCENTRATED LOAD FOR PONTOON-SERAPATE FLOATING BRIDGE
Authors:   Le Quy Don Technical University, Hanoi, Vietnam, Nguyen Manh Thuong
Published: January 2024

The pontoon-separate floating bridges have many advantages to apply to the construction of civil floating bridges in Vietnam. This article presents the study of the influence of beam stiffness on the force transmission of concentrated load to the pontoon and the bending moment in the beam caused by this load, as a basis for designing civil poonton bridge to carry loads for small tonnage motor vehicles serving rural traffic. The author uses theoretical research methods using SAP2000 software. The results show that the moment in the beam is directly proportional to the stiffness of the beam. The transmission of force to pontoon away from the force application point is also directly proportional to the stiffness of the beam. Initially, the force transmitted to the pontoon near the force application point is inversely proportional to the beam stiffness, and then directly proportional to the beam stiffness.
DELIMITAÇÃO SEMÂNTICA DE CONSCIÊNCIA EM TEXTOS DE ALLAN KARDEC:
Authors: Prates Luciana Cangussu
Published: January 2024

No presente trabalho, apresenta-se uma reflexão introdutória sobre como um material discursivo do Espiritismo descreve o fenômeno da consciência. Para tanto, toma-se como base alguns contextos enunciativos de textos espíritas que refletem sobre a referida temática, a saber: dois livros do francês Allan Kardec, O Livro dos Espíritos e O Evangelho segundo o Espiritismo, considerados pelos espíritas como obras básicas do Espiritismo. No intuito de refletir sobre uma possível delimitação semântica de “consciência” a partir desses textos, este estudo visa clarear, por meio de revisão  bibliográfica, como as ideias espíritas de “acesso à lei de Deus”, de “autoconhecimento” e de “consciência de si”, oferecem, em nível discursivo, elementos que orientam o entendimento de “consciência” nessa religião, a qual, em estudos futuros no  campo das Ciências da Religião, pode ser comparada às concepções de “consciência” de outras tradições religiosas
INFLUÊNCIA DA CULTURA SOBRE A CIÊNCIA E A PRÁTICA MÉDICA:
Authors: Almeida Angelica Aparecida Silva de , Almeida Alexander Moreira
Published: January 2024

Diversos aspectos da cultura podem impactar a ciência e prática médica, mas muitas vezes esses fatores não recebem a atenção devida. Este artigo aborda diferentes fatores culturais que geraram teorias e práticas discriminatórias da ciência e prática médica em relação a raça e a religiões mediúnicas no Brasil na primeira metade do século XX. Inicialmente, com base em fontes primárias, serão apresentadas as perspectivas dos médicos sobre a questão racial e então são analisados fatores cognitivos (etnocentrismo e preconceitos), socioeconômicos (não considerar a desvantagem econômica) e históricos (urbanização, prestígio da eugenia, construção do país) que influenciaram negativamente suas posturas. Posteriormente, também com base nas fontes primárias, apresentamos e analisamos o discurso médico sobre a loucura espírita, onde as vivências mediúnicas são entendidas como sintomas ou causas importantes de doenças mentais graves. A seguir, são analisados aspectos religiosos (catolicismo), filosóficos (materialismo e visão de ciência) que influenciaram esse discurso. Conclui-se pela necessidade de se atentar para a influência de fatores culturais nos discursos e práticas de diversas áreas da ciência, bem como no cuidado aos limites das áreas de abrangência de cada disciplina científica.
REFLEXÕES SOCIOCULTURAIS E FENOMENOLÓGICAS SOBRE O CORPO:
Authors: Oliveira Renato Alves de
Published: January 2024

O objetivo deste artigo é refletir sobre os aspectos socioculturais e fenomenológicos do corpo. No campo sociocultural, há uma eleição de um tipo de corpo: magro, malhado e jovem. Esse corpo se torna objeto de consumo da sociedade. É um tipo de corpo patrocinado pela indústria da beleza, pela mídia, pela moda e pela sociedade de consumo. O aspecto fenomenológico trata do modo como o corpo se apresenta e se manifesta objetiva e subjetivamente. O corpo é manifestação da dimensão mundana, temporal, mortal, sexuada, pessoal, social, histórica e expressão da subjetividade do ser humano. A metodologia é bibliográfica e busca manter um diálogo com autores que refletem sobre os aspectos socioculturais e fenomenológicos do corpo. O percurso metodológico consiste, primeiramente, na apresentação dos aspectos socioculturais e depois dos fenomenológicos do corpo. As considerações finais mostram que aspecto sociocultural concentrou-se no aspecto visível e objetivo do corpo e a dimensão fenomenológica no seu aspecto subjetivo e humano. É preciso ter uma visão integrada sobre os dois aspectos.

CRISES DE UM BRASIL LAICO, CRISES DO ENSINO RELIGIOSO
Authors: Nass Luzinete
Published: January 2024

Neste artigo, procuramos contribuir com as reflexões sobre a polêmica existência do Ensino Religioso (ER) em um Brasil laico e envolto historicamente em diversas crises sociais, políticas e econômicas. Por meio de um estudo bibliográfico, problematizamos o ER na escola pública, dialogando com as discussões trazidas pelas proposições legislativas, educacional e científica, abordando brevemente o contexto da pandemia que atinge o país desde 2020, agravada pelas decisões políticas do governo brasileiro no período. Nesses anos pandêmicos observamos as dificuldades enfrentadas pela educação em geral, uma vez que a necessidade do ensino remoto e virtual promoveu novos contornos às relações de ensino-aprendizagem. Em relação ao ER, o novo normal permitirá ainda que algumas reflexões acerca da religião, das religiosidades e da espiritualidade sejam atualizadas, uma vez que, em contextos de crise, há um maior apelo às religiões e experiências religiosas podem ser aprimoradas. Na literatura, as propostas recentes para o ER abordaram não só questões sobre legitimidade, legislação, e o confronto com a laicização no ambiente educacional, mas procuram recuperar também o âmbito emocional e afetivo da religião que, em contextos graves como o da recente pandemia, poderá – e deverá – ser abordado em sala de aula.

Published: January 2024

This work aimed to evaluate the Random Forest algorithm performance to predict mechanical digging loss of the peanut crop. Four approaches were tested: only soil texture data, soil texture + TPI, soil texture + TWI, and soil texture + TPI + TWI. The model's performance was evaluated regarding precision (coefficient of determination) and accuracy (mean absolute error). The results found in this work proved promising in predicting peanut digging losses. Our models achieve results with an approximate 100 kg ha-1 prediction error. In addition, incorporating one or more topographical indexes in conjunction with soil texture data as features notably improves the models' precision and accuracy.

Authors: Figuerêdo José Solenir L. , Ferreira Marcos Eduardo de C. , Calumby Rodrigo T.
Published: January 2024

Traditional soil fertility analyzes are laborious, expensive, timeconsuming and produce hazardous waste. Although many works using machine learning (ML) has been done to address these issues, some algorithms and dimensionality reduction strategies require further investigation. Therefore, in this study we evaluated the potential of Support Vector Regression and Ridge regression in determining soil attributes, and compared principal components regression and partial least squares regression (PLSR). The results showed that Ridge was the most effective model. In addition, our experiments revealed that PLSR was able to achieve statistically equivalent results, and in some cases superior to the baseline, but using a much smaller average number of components.

Management als gesellschaftliche Institution Eine soziologische Analyse von Funktionen und Folgen in system- und handlungs- theoretischer Perspektive
Authors: Reinbacher Paul
Published: January 2024

Die für moderne, westliche Gesellschaften feststellbare infla- tionäre Zunahme an Management-Imperativen mit ihrem Ideal einer formalen „Zweckrationalität“ der Effektivität und Effizienz sowie ihrem darauf beruhenden Potential zur Legitimation des Handelns in unterschiedlichen sozialen Kontexten lässt sich in soziologischer Perspektive als Prozess der gesellschaftlichen Institutio- nalisierung eines spezifischen Wertmusters interpretieren. Unter Rückgriff auf die system- und handlungstheoretische Heuristik von Talcott Parsons analysiert der Beitrag ausgehend von einem gesamtgesellschaftlichen Wertewandel der „longue durée“ in Richtung „instrumental activism“ und „institutionalized individualism“ die Funktionen und Folgen der Implementierung dieser kulturellen Werte in nor- mative soziale Strukturen durch „Management“ bei gleichzeitiger Berücksichtigung der analytisch unterscheidbaren, synthetisch aber untrennbar damit verbundenen Persönlichkeits- und Verhaltenskomponenten sozialen Handelns. Neben dieser Mehrdimensionalität erlaubt die Parsons’sche Perspektive eine Verbindung von gesellschaftlicher Makro-, organisationaler Meso- und interaktionaler Mikroebene, sodass es möglich wird, Management als genuin soziales Phänomen gesellschafts- und organisationstheoretisch informiert in den Blick zu nehmen. Dem evolutionä- ren Vorteil von Management, nämlich einer Stärkung adaptiver Funktionszusam- menhänge in Systemen („adaptive upgrading“), steht als Nachteil die Erzeugung integrativer Spannungen („integrative strains“) gegenüber. Daher ist es theoretisch nicht sehr verwunderlich, dass in den letzten Jahren sowohl praktisch als auch empirisch komplementäre und kompensierende Konzepte (wie z. B. Soziales Kapi- tal, Communities oder Corporate Social Responsibility Einzug) gehalten haben.
Der Einfluss von Vertrauen auf die Akzeptanz freiheitseinschränkender Maßnahmen zur Bekämpfung der COVID-19-Pandemie und seine Bedingungen Eine EU-weite Mehrebenenanalyse
Authors: Kamper Patricia
Published: January 2024

Auf den Ausbruch der COVID-19-Pandemie wurde in (fast) allen europäischen Ländern mit Maßnahmen reagiert, welche die Freiheit des Einzelnen teilweise stark einschränkten. Damit die Maßnahmen ihre Wirksamkeit entfalten konnten, bedurften sie der Akzeptanz der Bevölkerung. Doch wovon hängt diese Akzeptanz ab? Wird sie vom Vertrauen der Bürgerinnen und Bürger untereinander oder vom Vertrauen in den Staat beeinflusst? Und welche Rolle kommt der Strenge der Maßnahmen in diesem Zusammenhang zu? Zur Beantwortung dieser Fragestellungen werden im folgenden Artikel die Daten des Eurobarometers 93.1 mittels einer Mehrebenenanalyse ausgewertet. So lässt sich zum einen feststellen, dass sich das Vertrauen je nach Form unterschiedlich auf die Akzeptanz der Maßnahmen auswirkt. Zum anderen ist ein gemeinsamer Effekt von Vertrauen und der Strenge der Maßnahmen feststellbar.
Religion and Climate Change in Africa: A gendered perspective
Authors: Mupangwa Terence , Chirongoma Sophia
Published: January 2024

This chapter reflects on the interface of religion, gender, and climate change in Zimbabwe. The writing of this chapter has been ignited by the ongoing climate change induced catastrophes such as cyclones and drought in Southern Africa. Cognizant of the pivotal role of religion in shaping people’s worldviews not only in Southern Africa but the rest of the continent, the chapter discusses how religion shapes people’s relationship with ecology. Informed by the African feminist theory, the chapter adopts a gendered perspective. It, therefore, discusses the intertwinement between African women’s experiences of patriarchy and the earth’s exposure to ecological degradation. Acknowledging the efficacy of fulfilling Sustainable Development Goals 4, 5, and 13, the chapter concludes by restating the importance for the church in Zimbabwe to adopt an agenda for gender empowerment and ecological stewardship.

Published: January 2024

The role of nonspecific immune inflammatory vascular response as a link in general pathogenetic mechanisms with change in the elastic properties of the arteries and phenomena of destructive bone changes has attracted great attention. We examined 104 patients (mean age 54.03 ± 9.56) who were divided into three groups: healthy women, with arterial hypertension (AH) and osteopenia and with AH and osteoporosis. The immune inflammatory response markers, endothelial dysfunction, and hormonal and mineral-vitamin status were analyzed simultaneously with 24-hour ambulatory blood pressure monitoring, parameters of vascular wall stiffness, and densitometry to clarify the predictors of cardiovascular and degenerative bone changes in postmenopausal women. For patients with AH and osteopenia, significant parameter associated with the risk of osteoporosis was pulse wave velocity; increase of which exceeded 12.05 m/s was associated with increased risk of osteoporosis by 3.8 times. The levels of pro-inflammatory parameters, interleukin (IL) 6 and 8, tumor necrosis factor-α, high-sensitivity С-reactive protein, and parathyroid hormone were increased and the levels of progesterone and IL-10 were decreased. Timely specialized multidirectional studies of biochemical and instrumental parameters (pulse wave velocity and densitometry) can be the basis for the development of personalized prevention and treatment strategy for women to prevent dangerous cardiovascular and bone complications.

We experienced a case of endotracheal tube damage during maxillomandibular osteotomy found by bronchofiberscope. The patient was a 22-year-old man, scheduled for maxillomandibular osteotomy under general anesthesia for the treatment of two jaws deformity. Tracheal intubation of Microcuff subglottic endotracheal tube (I.D.7.5 mm made by Halyard Health Care Inc.) was via the left nasal cavity. The surgery started from maxilla and became the maxillary transection approximately 50 min later. There was the indication of the ventilation gas leak from the operation after the maxillary transection, but we confirmed that, and there was no tube in the clear abnormal findings with bronchofiberscope. Because the positive pressure ventilation was possible, and the ventilation had no problem, we decided to resume surgery. After maxillary fixation was completed approximately 3 and a half hours later, and confirming with bronchofiberscope again, we confirmed an inflow of the blood in a tube and confirmed a tube laceration to around 4–5 cm from the nasal cavity entrance. We decided to conduct tube exchange. After the surgery, the cause of tube rupture was examined; it was then found that the tube was damaged by a bone chisel used during maxillary bone dissection. When there is doubt about a endotracheal tube damage, confirmation of the inner surface using a bronchofiberscope is useful, and it is important to grasp the case early.

Authors: M. Alfagih Iman
Published: January 2024

Nanoparticles (NPs) offer a promising solution for orally delivering therapeutic substances due to their capability to surpass traditional drug delivery system (DDS) limitations like low solubility, bioavailability, and stability. However, the possible toxic effects of using NPs for oral therapeutic delivery raise significant concerns, as they might interact with biological systems unexpectedly. This chapter aims to comprehensively understand the potential toxicity of NPs employed in oral therapeutic delivery. Factors such as size, surface area, surface charge, and surface chemistry of NPs can impact their toxicity levels. Both in vitro and in vivo models have been utilised to evaluate NPs toxicity, with in vivo models being more suitable for anticipating human toxicity. The possible toxic consequences of different NPs varieties, including polymer, lipid, and metal NPs, have been documented. Ultimately, grasping the potential toxicity of NPs in oral therapeutic delivery is essential for creating safe and effective DDS.

A Study of Morphological Changes in the Coastal Areas and Offshore Islands of Sudarban Coastline Using Remote Sensing
Authors: Sarathi Mahato Partha
Published: January 2024

The Sundarbans, located along the coastal areas of India and Bangladesh, is the largest remaining single block of mangrove forest in the world, covering approximately 1 million hectares (10,000 km2) of the Ganges-Brahmaputra delta. This unique ecosystem is under threat from major disturbances such as sea level rise and alterations in water flows from the Himalayan headwaters. There have been very few studies on the current status and dynamics of the Sundarban’s coastline. To address this knowledge gap, we conducted a study utilizing Landsat images spanning from 1975 to 2022. Our findings reveal that the rates and directions of erosion and accretion varied across the different periods. During the 1994–2005 interval, erosion reached its peak with a land loss rate of ~17 km2 per year. However, this rate substantially declined in subsequent periods to ~8 km2. Accretion, on the other hand, showed a rate of ~7 km2 per year between 1975 and 1988 but declined to approximately ~6 km2 per year between 1988 and 1994. While the accretion rate has declined in recent years, the erosion rate has remained relatively high.

In this chapter, we delve into the multifaceted world of human emotions through the lens of advanced analysis techniques, aiming to unlock a deeper understanding of human behavior and decision-making processes in our digital landscape. We begin by illustrating the complexity of human emotions and the significance of accurate emotion detection across various applications, from marketing and customer relationship management to healthcare and social media monitoring. This context leads us to discuss state-of-the-art emotion detection methods, including transformer-based models, context-aware emotion detection, physiological signal recognition, and multimodal emotion analysis. Here, we adopt a systematic approach to emotion analysis, utilizing the transformer-based architecture fine-tuned on a tweets dataset. Our methodology achieves an accuracy of 82.53%, a precision of 82.79%, a recall of 82.53%, and an F1 score of 82.29% in predicting emotional categories. The chapter also scrutinizes challenges, limitations, and ethical considerations in this field, including ambiguity, subjectivity, and cross-cultural variations. Finally, we glance into the future of emotion analysis, focusing on integrating emotional intelligence into artificial intelligence systems and developing personalized techniques. We aim to spur further research and collaboration in this field, thus enriching our understanding of the dynamic role of human emotions in our interconnected world.

Sentiment Analysis of Social Media Using Artificial Intelligence
Authors: Victor Rajan K.
Published: January 2024

Social media refers to the development and sharing of sentiment, information, and interests, as well as other forms of opinion via virtual communities and networks. Nowadays, social networking and micro blogging websites are considered reliable sources of information since users may openly express their opinions in these forums. An investigation of the sentiment on social media could assist decision-makers in learning how consumers feel about their services, products, or policies. Extracting emotion from social media messages is a difficult task due to the difficulty of Natural Language Processing (NLP). These messages frequently use a combination of graphics, emoticons, text, etc. to convey the sentiment or opinion of the general people. These claims, known as eWOM (Electronic Word of Mouth), are quite common in public forums where people may express their opinions. A classification issue arises when categorizing the sentiment of eWOM as positive, negative, or neutral. We could not use standard NLP tools to examine social media sentiment. In this chapter, we will study the role of Artificial Intelligence in identifying the sentiment polarity of social media. We will apply ML(Machine Learning) methods to resolve this classification issue without diving into the difficulty of eWOM parsing.
