Ageing (as known as eldering, senescence) is a genetically and epigenetically programmed pathophysiological process. Velocity of biological ageing is defined as balance between alteration and reparation of body structures. According to last World Health Organization (WHO) highlights ageing still stays an extremely actual scientific, social and demographic problem: in 2020 total number of people older than 60 years and older was 1 billion people; in 2030 future number may be 1,4 billion people, in 2050 — 2,1 billion people. Absence of single universal theory of aging nowadays is reason for scientifical and clinical collaboration between biologists and doctors, including endocrinologists. Designing of potentially effective newest anti-ageing strategies (such as natural/synthetic telomerase regulators, mesenchymal stem cells etc.) is of interest to scientific community. The aim of present article is a review of modern omics (genomic, proteomic, metabolomic) ageing mechanisms, potential ways of targeted prevention and treatment of age-related disease according to conception of personalized medicine. Present review is narrative, it does not lead to systematic review, meta-analysis and does not aim to commercial advertisement. Review has been provided via PubMed article that have been published since 1979 until 2022.

Authors: Absatarova Yu. S. , Evseeva Yu. S. , Andreeva E. N.
Published: November 2023

Polycystic ovary syndrome (PCOS) is one of the most pressing problems in endocrine gynecology. The main signs of the disease are hyperandrogenism, menstrual and/or ovulatory dysfunction, and polycystic ovarian structure according to ultrasound. Women with PCOS are at risk for developing metabolic syndrome, type 2 diabetes, cardiovascular disease, and endometrial cancer. In this connection, the pathogenetic mechanisms of the occurrence of this syndrome are continuously studied and new methods of treatment are being sought. PCOS is characterized by a wide range of various disorders of the neuroendocrine regulation of the reproductive system. The main focus of the review is aimed at summarizing information about the etiological role of neuropeptides and neurotransmitters, such as phoenixin, galanins, orexins, GABA, in the pathophysiology of PCOS and about the possibility of their use for diagnostic and therapeutic purposes. In recent decades, the interest of scientists has been focused on the study of KNDy neurons, because it is the kisspeptin synthesized by them that is one of the main regulators of the hypothalamic-pituitary-ovarian axis. This article discusses data on the significance of KNDy neurons in the pathogenesis of the syndrome. Information is provided on the effect of elevated levels of androgens and anti-Müllerian hormone on GnRH neurons. Also analyzed are studies on functional and structural disorders in the hypothalamus in PCOS. Literature search was carried out in national (eLibrary, CyberLeninka.ru) and international (PubMed, Cochrane Library) databases in Russian and English. The priority was free access to the full text of articles. The choice of sources was prioritized for the period from 2018 to 2023.However, taking into account the insufficient knowledge of the chosen topic, the choice of sources dates back to 1998.
Flexural Toughening of Hooked-End Steel Fibers Reinforced Mortars
Authors: Gullì Giuseppe , Bertino Riccardo , Grungo Francesco , Palamara Davide , Bruzzaniti Paolo , Calabrese Luigi
Published: November 2023

This paper investigated the effect of hooked-end steel fiber at varying fiber content on the flexural toughening of fiber reinforced cement mortars (FRCM) by using three-point bending tests. In particular, to preserve the mortar workability, three low weight fractions (0.3%, 0.5% and 0.7%) and two cement matrices (M10 and M15) were investigated. The results showed that the mechanical bending behavior of the FRCM increases significantly at increasing fiber content and cement plaster matrix. An important aspect that has been addressed is how the flexural toughening is varied at varying fiber content and the type of matrix. Especially, all composite mortars exhibited a toughness index (TI) in the range of 10–45, indicating a suitable strengthening and toughening effect supplied by the hooked-end fiber addition. The best TI value, equal to 44, was experienced for the M10-D7 batch characterized by 0.7 wt.% of hooked-end steel fibers and an M10 cement matrix. Furthermore, unlike unreinforced concrete where brittle and unexpected failure occurs dominated by a sudden and catastrophic propagation of tensile cracks, the FRCM samples exhibited a ductile behavior with a marked residual post-crack resistance even for composites mortars with low metal fiber content.

Published: November 2023

Dalam penelitian ini, kami mengamati ikan dari tujuh lokasi sungai yang berbeda di Yogyakarta dengan mengevaluasi berat pencernaannya. Penebaran mikroplastik pada saluran pencernaan ikan dilakukan berdasarkan faktor abiotik seperti suhu sungai, keasaman, dan butiran mikroplastik aliran sungai untuk dibawa ke saluran pencernaan ikan. Kadar mikroplastik dalam tubuh ikan dapat dideskripsikan secara matematis menggunakan persamaan diferensial. Kami membangun model berdasarkan diagram aliran hubungan antara masing-masing variabel. Jadi kami memiliki sistem diferensial sebagai model. Pada langkah selanjutnya kami menganalisis model secara analitis. Untuk menunjukkan keakuratan model, kami membuat simulasi menggunakan simulasi data ke sistem dan membandingkannya dengan hasil komputasi menggunakan data observasi. Di akhir penelitian, kami memberikan justifikasi untuk faktor abiotik yang paling berpengaruh terhadap penyebaran mikroplastik.
[In this research, we observe the fish from seven different river location on Yogyakarta by evaluating its digestive weight. We investigate the microplastics spreading on fish digestive based on the abiotic factor such as river temperature, acidity, and river flow microplastics granules to be carried into the digestive tract of the fish. The rate of microplastics in the fish body can be describe mathematically using differential equation. We build a model based on the diagram flow of the relationship between each variables. Thus we have a differential system as the model. In the next step we analyze the model analytically. To show the accurancy of the model, we make a simulation using data simulation to the system and we compare it with the computing results using observation data. At the end of our research, we give a justification for the most influential abiotic factor for microplastic sreading.]

On continuity properties of the improved conformable fractional derivatives
Authors: Hasanah Dahliatul
Published: November 2023

The conformable fractional derivative has been introduced to extend the familiar limit definition of the classical derivative. Despite having many advantages compared to other fractional derivatives such as satisfying nice properties as classical derivative and easy to solve numerically, it also has disadvantages as it gives large error compared to Riemann-Liouville and Caputo fractional derivatives. Modified types of conformable derivatives have been proposed to overcome the shortcoming. The improved conformal fractional derivatives are declared to be better approximations of Riemann-Liouville and Caputo derivatives in terms of physical behavior. In this paper, properties concerning continuity of the improved conformable fractional derivative are investigated. We prove the relation between -differentiable and continuity of a function and corresponding interior extremum theorem. We also prove the properties close to Rolle’s Theorem and Mean Value Theorem for the improved conformable fractional derivatives.

Published: November 2023

This review is an attempt to explore the challenges that need to be addressed to fully utilize the potential of ceramic-based functionally graded cutting tools (FGCTs). The various aspects covered in the review include the most recent experimental and numerical work related to FGCTs, the current research trends and the need for these tools, the identification of potential material combinations, synthesis techniques and their limitations, and finally a presentation of the most recent work. To find general tribological performance, various wear mechanisms involved in the cutting process are explored. Some recent experimental and numerical works related to the self-lubricating phase in functionally graded structure and the need for self-lubricating ceramic tools, identifying potential high-temperature solid lubricants, and their limitations are also discussed. More recent and dominating fabrication methods are also discussed in detail along with a brief review of some promising methods. The implementation of numerical modeling and computational frameworks validated through experiments is found to lead to the design and development of cost-effective and efficient FGCTs. Finally, some research gaps are identified and future directions for innovative FGCT materials are proposed.
FERTILITY PRESERVATION: Exploring the complexities of posthumous reproduction in fertility preservation for oncology patients with poor prognosis
Authors: Polyakov Alex , Rozen Genia
Published: November 2023

The field of fertility preservation (FP) for oncology patients has evolved significantly in recent years, offering new possibilities for individuals with life-threatening illnesses. We commend Jones et al. for their comprehensive ethical review of offering FP to patients with poor prognoses, acknowledging the potential benefits that it may bring. ‘Poor prognosis’ in this context implies a high likelihood of death due to cancer progression. We highlight the importance of considering posthumous reproduction, involving the use of cryopreserved gametes or embryos to conceive a child after one or both partners have passed away, a topic briefly mentioned by Jones et al. Posthumous reproduction raises complex ethical, logistical, and legal questions. Distinctions between cryopreserved sperm and oocytes are discussed, with each scenario presenting unique challenges. The article also examines the complexities faced by same-sex couples in posthumous reproduction, addressing issues related to donor selection, legal parentage, and rights. Legal and regulatory aspects play a crucial role, including obtaining clear and legally valid consent, defining parental rights, navigating surrogacy laws, and addressing inheritance and estate planning. Ethical dilemmas require healthcare professionals to ensure informed decision-making, consider psychological impacts, and offer information on alternative family-building options.

Lay summary

Cancer treatments can have a negative impact on a person’s ability to have children, and some cancer survivors may end up being unable to conceive. Fortunately, there are currently available technologies that can help preserve fertility for these patients. These options include freezing eggs or sperm before starting cancer treatment. For patients who have been diagnosed with cancer and have a poor prognosis, meaning they are not likely to survive their illness, it is crucial to think about what happens to their frozen eggs and sperm in case of their death. This process of conceiving a child after someone's passing is known as ‘posthumous reproduction’. In our article, we explore the ethical, legal, and logistical challenges that the surviving partners of patients who may not live long enough to have a child with their frozen eggs or sperm might face. We pay particular attention to same-sex couples because their surviving partners often encounter more obstacles. In some countries, posthumous reproduction in these circumstances is even prohibited by law. There is a significant variation in the regulations related to posthumous reproduction, both between different countries and within individual countries. These differences need to be carefully considered when healthcare professionals counsel patients and their family members.

Pesantren and the Kitab Kuning: Pesantren Dynamics and Its Influence on the Kitab Kuning Traditions in Sukabumi
Authors: Yuningsih Yeni Ratna , Abubakar Irfan , Rahman Farhan Muzhaffar
Published: November 2023

PurposeThis study aimed to better understand how the modernization of Islamic education has affected the patterns of learning Classical Literature (Kitab Kuning) in traditional pesantren in Sukabumi, West Java.MethodThis study used a qualitative method, by conducting in-depth interviews with 30 Kyais and pe-santren teachers in six pesantrens in Sukabumi. The six pesantrens represented old pesantren and were located in both the regency and city of Sukabumi.Results/findingsIn general, the modernization of Islamic education in pesantren in Sukabumi has not had much impact on the ways of learning Kitab Kuning which still apply classical methods. Exceptions oc-cur in a small number of pesantren which still all adhere to a pure Salafiyah system, such as Pe-santren An-Nidzom, Selabintana, and Pesantren Assalafiyah, Babakan, Tipar.ConclusionDespite minimal modernization of their education system, pure Salafiyah pesantrens have tried to apply limited modernization to the pattern of teaching of Kitab Kuning. Two new models have been adapted: First, the application of the Amtsilati method, a fast way of learning the Kitab Kuning discovered in 2002. Second, the application of an intensive learning strategy by placing selected students in intensive classes. Further studies need to be carried out to explore the effec-tiveness of the new method of learning Kitab Kuning in comparation to the classical one.

As an ecosystem, the mangrove ecosystem serves various purposes. The objectives of this study are to (1) identify the community structure of the important value index; and (2) evaluate the importance of the mangrove species diversity index in Pulias Bay in Ogodeide District, Tolitoli Regency. The study was conducted in 2021 using a quantitative descriptive methodology and survey method. The number of discovered species will be used to establish the species composition. The structure of the mangrove communities is being evaluated by calculating the relative density (RD) and frequency (FR). The data is tabulated to calculate the Important Value Index (IVI) value according to the Shannon-Wiener formula. There were 18 different species of mangroves discovered, including Rhizophora apiculata, Rh. mucronata, Rh. stylosa, Bruguiera parviflora, B. gymnorrhiza, Ceriops tagal, C. decandra, Sonneratia alba, S. caseolaris, S. ovata, Avicennia lanata, Xylocarpus moluccensis, Acrostichum aureum, Nypa fruticans, and Pemphis acidula. The Rhizophoraceae family predominated at each observation station, according to the findings of the vegetation analysis. Meanwhile the most rarely found species of mangrove were Acrostichum aureum, Sonneratia casiolaris, and Xylocarpus moluccensis, each with two specimens. The community structure reveals that X. moluccensis has the lowest IVI value of 12.7%, while Rhizophora mucronata has an IVI value of 101.3%. The mangrove Diversity Index (H') has a value of 2.48 and meets the standards for moderate diversity. Physical and chemical parameter measurements often indicate that the four stations or sites where the data was collected have similar conditions. Interestingly, we also found Avicennia lanata, a mangrove species that falls under the Vulnerable category. The collected information can be used to manage the mangrove forest in Pulias Bay in the Ogodeide Sub-District of the Tolitoli Regency and serve as a database for efforts to conserve mangroves and mitigate the effects of global warming.

Published: November 2023

Cactiform succulents, belonging to the Euphorbia genus, are distinctive species found in the arid and semi-arid ecosystems of Macaronesia and the Arabian Peninsula. Resembling cacti in appearance, they exhibit unique morphological characteristics, such as succulent, green-stemmed structures with ribs, accompanied by a pair of stipular spines. These plants have evolved to thrive in well-draining substrates, including both surface and rocky soils, potentially as an adaptive strategy to combat edaphic drought conditions. Although initially associated solely with arid and desert environments, it is important to note that these cactiform succulents are not exclusively specialized for prolonged dry periods. Rather, they demonstrate morphological adaptations that help them endure arid conditions. The primary objective of this review is to provide an up-to-date synthesis of knowledge concerning cactiform succulents within the Euphorbia genus. It aims to underscore their capacity to flourish in both arid and semi-arid zones, while underscoring the pressing conservation challenges that threaten these plants with degradation and potential extinction. The prevailing climatic conditions, marked by extended and recurrent droughts exacerbated by escalating temperatures, climate fluctuations, and escalating human impact, collectively pose a formidable obstacle to conserving these cactiform succulents and their respective ecosystems. All these threats jeopardize these invaluable natural resources, which hold multifaceted significance spanning environmental, socio-economic, and medicinal domains.

Aus dem Grab der kuschitischen Königin Amanischacheto wurde im Jahr 1921 eine Sammlung stark zerstörter gedoppelter Rohrblattinstrumente (Auloi) geborgen, die sich bisher jedem Rekonstruktionsversuch widersetzt haben. Auf der Grundlage jüngster Erkenntnisse zur antiken Musik im Allgemeinen und dem Aulos im Besonderen wird hier eine neue Methode vorgestellt, die die Wiederherstellung der Instrumente mit einem hohen Wahrscheinlichkeitsgrad erlaubt. Auf dem Weg dahin müssen einige Hypothesen zugunsten eines tieferen Verständnisses der Herstellung und Verwendung des Aulos aufgegeben werden. Eines der Instrumente wird beispielhaft im Detail vorgestellt. Während es harmonische Grundcharakteristiken mit anderen bekannten Instrumenten teilt, bietet es andererseits erstmals einen archäologischen Beleg für die berühmte Enharmonik der antiken griechischen Musik.
Kisah Nabi Luth dan Kaum Sodom dalam Al-Qur’an (Analisis Semiotika Saussure dan A.J. Greimas)
Authors: Syam Ishmatul Karimah , Taufiq Wildan , Solehudin Solehudin
Published: November 2023

This research aims to examine more deeply the study of semiotics on the story of people who were doomed in the Qur'an, one of them being the Sodomites. Examining the values and messages conveyed through the signs and symbols in the story with a semiotic approach initiated by Ferdinand de Saussure in the form of signifiers and signifieds, syntagmatic and paradigmatic relations. As well as with the narrative semiotic approach initiated by A.J. Greimas in describing the storyline of the Prophet Luth. This study uses a descriptive-analytic method which is based on qualitative data about the story of Prophet Luth and the people of Sodom in the Qur'an using the semiotic approach of Saussure and A.J Greimas. Many studies of the Qur'an have begun to be carried out using a semiotic approach in its interpretation. Deeper research on one of the stories in the Qur'an with a semiotic approach will lead us to many lessons and reveal the secrets behind the symbols and signs that exist in it. The result of this research is, it is found that the story of Prophet Luth and his people in the Qur'an is repeated many times by Allah with different verses and different storylines. In fact, it is part of the symbol that repetition occurs to give its respective purpose in several different places and as a complement to one another. Likewise, with Saussure's theory, there are many symbols and signs that God sent to commemorate them as well as us. The actions they commit are called heinous acts because they are the same as adultery, so the punishment for them according to fiqh scholars is the same as haad for adultery. As well as the narrative story of Prophet Luth which is more directed in a more directed manner with the Greimas narrative. Then the teachings and moral messages from the story of Prophet Luth can be wisdom and lessons for the people after him. This research is still limited to symbols in general, so future research can reveal symbols and signs and the secrets behind the language and every word in the verse.

Previous interpretation of QS. al-Anbiya’ ayat 7 states that this verse is the argument that the messenger is only from men. However, it turns out that the word rijāl in QS. al-Anbiya’ ayat 7 there are indications of the meaning of women which is correlated with rijāl in other verses in the Koran. This shows that there are differences in interpreting interpretations depending on the interpreter's period. This study aims to examine the historical meaning, historical significance, and contemporary dynamic significance of QS. al-Anbiya’ ayat 7   to find relevant and progressive meanings to the present. This research was assessed using qualitative methods. literature review comes from data sources related to research with the ma'nā cum magzā approach theory. This theory was chosen because it has a structured and comprehensive work tool in offering interpretations of the Koran, because it has united classical science with multidisciplinary knowledge. This research got the result that QS. al-Anbiya’ ayat 7 actually does not focus on the issue of apostolic identity, but this verse indicates a connection with the statement of the Quraysh who doubted the Prophet Muhammad SAW as a messenger, then, in terms of historical significance, the message of the verse is an affirmation that the Prophet Muhammad SAW receiving revelation and in terms of contemporary dynamic significance reveals the importance of having competence in preaching which includes several strategies to approach aspects of sociology, psychology, culture and the wise command to ask scientific professionals who are experts in their fields.

Published: November 2023

The aim of this paper is to present an ideal Qur'anic leadership model, using the perspective of the Qur'an and the interpretation of the story of the Prophet Sulaiman AS as the main source of inspiration. The writing of this work also used qualitative techniques based on literature searches and the Maudhu'i method. This paper concludes that the message of wisdom in the Al-Qur'an conveys a leadership concept that includes intellectual and spiritual capabilities, capabilities for cadre formation and good communication, good managerial capabilities, good social responsibility, and a disciplined and firm attitude. Through revitalization efforts, it is hoped that the idea of a leadership prototype from the perspective of the Qur'an will be a trigger for the birth of benefits in world life, especially in Indonesia. The weakness of this article is that it only discusses the leadership prototype of one prophet's story. In subsequent writings, this study suggests exploring more specifically the Al-Qur'an exegetical literature on leaders in order to explore more diverse and comprehensive Qur'anic leadership values as criteria for quality leaders.
Organizações e Modelos de Homens: A Exclusão do Sujeito nas Teorias Administrativas
Authors: Paes Ketlle Duarte , Paula Ana Paula Paes de
Published: November 2023

O objetivo desse artigo é fazer algumas considerações sobre a concepção de sujeito, para os estudos organizacionais, tendo em vista o avanço dos estudos sobre o tema nesse campo. Para isso, na primeira parte, abordamos os modelos de homem nas teorias administrativas - Econômico, Social, Administrativo, Organizacional, Funcional e Complexo– evidenciando como essas abstrações se distanciam de uma concepção de sujeito, para, na seção seguinte, recorrer à constructos da filosofia e da psicanálise lacaniana para esboça-la. Na terceira parte, abordamos o conceito de sujeito falta-a-ser lacaniano, apresentando o mesmo como um sujeito político, fundamental para a inserção de mudanças na sociedade, nos grupos e nas organizações. Na quarta parte, à guisa de conclusão, abordamos uma perplexidade: o sujeito político tem como motor a pulsão anarquista, que resulta de uma separação do corpo social, trazendo a difícil questão de como o impulso de mudança e transformação do sujeito é reconduzindo para o campo coletivo. Nessa operação, observamos a tendência dos sujeitos se reduzirem a indivíduos, integrando-se ao amor ideológico, rendendo-se à fantasia dos modelos de homem, que tende a excluir a noção de sujeito das teorias administrativas.

Systemic tools integration to fight fake news from a posthumanist perspective
Authors: Buzato Marcelo El Khouri
Published: November 2023

A theoretical-practical framework is proposed for an understanding of fake news stories from an interdisciplinary, ecological and posthumanist perspective. Key elements of three systemic approaches to meaning are integrated that allow for a symmetrical account of human and non-human agencies in fake news as a phenomenon.  The findings are descriptioons of (1) fake news as systemic material-semiotic activity that emerges from algorithmic capture of human emotion and social-discursive degrees of freedom; how pre-conscious/emotional triggers can be hacked by informational patterns in fake news pieces;  an “ontological syntax” of truthiness and falseness across institutional agencies in fake-news activity.
Da experiência televisual à experiência mediática: notas iniciais da definição de framework conceitual para análises de materialidades comunicacionais
Authors: Marquioni Carlos Eduardo
Published: November 2023

Especialmente a partir da segunda metade dos anos 1990, a digitalização potencializou o acesso no mesmo dispositivo a conteúdos que antes eram oferecidos em equipamentos tecnológicos específicos (inclusive em relação a materialidades associadas a ações práticas da vida cotidiana). Defende-se aqui que esse acesso unificado tem promovido uma abstração de “formas culturais”, acarretando potenciais desentendimentos durante a “decodificação” dos conteúdos acessados no gadget em uso. No artigo são apresentadas notas iniciais de framework conceitual em desenvolvimento que articula quatro perspectivas teóricas; extrapolação do que o autor intitulou anteriormente como experiência televisual, o framework experiência mediática almeja constituir alternativa para análises de materialidades comunicacionais para além do suporte tecnológico.
A Bahia negra não mostrada na TV: a invisibilidade dos quilombolas no telejornal BATV
Authors: Mesquita Giovana Borges , Araújo Danilo Borges e Silva de
Published: November 2023

O trabalho é fruto de uma pesquisa mais ampla, que analisa como a imagem dos quilombolas é construída por dois telejornais de maior audiência na Bahia e no Maranhão (estados como maiores números de comunidades quilombolas). Para esse artigo nos deteremos no BATV, telejornal que possui uma cobertura de 100% do estado da Bahia. Analisamos todas as edições jornalísticas no período de 2012 a 2019, disponíveis na plataforma Globoplay. No período foram veiculados 17.686 conteúdos jornalísticos sobre diversas temáticas, mas com relação à temática quilombola, o telejornal veiculou três conteúdos. Utilizamos como aporte teórico-metodológico a Teoria das Representações Sociais e a Teoria do Jornalismo. Destacamos que as imagens dos quilombolas são criadas pelo telejornal com produções de estigmas e estereótipos.
A ‘erosão do solo’ descrita em uma notícia: análise discursiva sobre a produção de sentidos envolvendo o ambiente rural
Authors: Maio Ana Maria Dantas de , Silva Marcelo Pereira da
Published: November 2023

A Análise de Discurso (AD) de linha francesa e a Análise Crítica de Discurso (ACD) fundamentam este estudo, que examina um enunciado jornalístico sobre os efeitos da erosão do solo na produção agrícola. A intenção é investigar como uma notícia sobre um problema típico do universo rural e/ou ambiental produz sentidos para interlocutores sem vínculos com o agronegócio. O enunciado apresenta sinais de polifonia, silenciamento e didaticidade que demarcam as condições de produção do texto, identificam endo e exogrupos, além de determinar uma linha de leitura, entre  outras possíveis. A análise conclui que esse discurso não conecta o problema da degradação do solo ao consumidor final. O sentido é interrompido no elo da produção rural, como se os efeitos da degradação do solo sofressem uma descontinuidade, sem afetar itens que são consumidos por habitantes urbanos.
Os sentidos e silenciamentos sobre a primeira infância no discurso do documentário “O começo da vida”
Authors: Doretto Juliana , Furtado Thais Helena
Published: November 2023

Este trabalho tem como objetivo compreender os sentidos sobre a primeira infância presentes no documentário “O começo da vida”. Para isso, por meio de conceitos da Análise do Discurso (AD), investigamos quem é o espectador imaginado, a organização discursiva do filme e os efeitos de verdade estabelecidos por ele. Concluímos que, junto com o sentido preponderante de valorização dos cuidados na primeira infância, a obra carrega outros sentidos, como o da possibilidade de um futuro predeterminado para algumas crianças, principalmente as que vivem em vulnerabilidade social. Além disso, percebemos que os “efeitos de verdade” construídos para a argumentação do filme, ou seja, as condições tecidas por seus realizadores para que a narrativa proposta sobre a primeira infância seja considerada “válida”, carrega silenciamentos de sentido.
PHYSICAL EDUCATION AS A CURRICULAR COMPONENT: INTELLECTUALS, KNOWLEDGE AND TEACHING
Authors: Furtado Renan Santos
Published: November 2023

This is a theoretical study that aimed to reflect on the theoretical-practical developments of what it means to treat Physical Education as a curricular component. The motivation for writing this work goes back to the author's experiences as a basic education teacher. For the theoreticalmethodological progress of the study, we made use of a specialized discussion of the area on the subject, guided by questions related to the Physical Education teacher as an intellectual, the meaning of the term curricular component, the knowledge that Physical Education addresses at school and the didactic consequences of thinking about the thematization of body culture of movement in basic schooling. The study pointed out that the condition of a curricular component delegates to Physical Education a set of responsibilities and rights, which revolve around the tension between its historical logic of school activity, with the contemporary meaning that we claim as a curricular component with the status of a discipline school education.
Ancestral transplantation as a matter of gender: Narrating us, Wigudun
Authors: Maciel Lucas da Costa , Pereira Bru
Published: November 2023

In this short essay, we want to revive some reflections reported to us by Yineth Muñoz, a person of Guna origin, an Indigenous people from Panama, to think with her what gives form to gender. We intend to critically imagine (Hartman, 2019) what happens to this concept – a technology, a somato-political fiction, and a material cutout – once the elaborations, concerns, and agency recalled and presented by Yineth's narratives traverse it. In this sense, the effort is not to explain Guna's gender, meaning to understand it as an object of ethnological elaboration. We would like to consider what comprises gender when it comes to metaphorizing – as an equivocal concept – the problems and reflections posed by Yineth. We will begin by going back to Yineth's considerations, which implicate gender in a series of other procedures and recursiveness that, we think, assist in raising questions to complicate some of the metaphors underlying mainstream descriptions concerned with matters of gender. Therefore, ours is an exercise concerned with a transfeminist engagement with the problem: to implicate oneself in it, not to explain it.
Agricultura familiar em circuitos curtos de abastecimento alimentar: comercialização agroecológica em Chapecó/SC
Authors: Fossá Juliano Luiz , Renk Arlene , Matte Alessandra , Pessinato Bruna
Published: November 2023

A agricultura familiar é a forma predominante de agricultura no município de Chapecó/SC (IBGE, 2017). Os Circuitos Curtos de Abastecimento Alimentar (CCAAs) se inserem neste modelo de agricultura como uma alternativa possível de produção e consumo para aquelas famílias que, no processo histórico, ficaram à margem das cadeias do agronegócio, especialmente a partir da produção agroecológica. Nesse sentido, o objetivo desta pesquisa é analisar as dinâmicas de comercialização em CCAAs da produção agroecológica no município de Chapecó. Em termos metodológicos, este estudo caracteriza-se essencialmente como qualitativo, o instrumento de coleta de dados se deu por meio de entrevista e os resultados do campo de pesquisa foram realizadas por meio da análise de conteúdo. Os principais resultados demonstram que as famílias entrevistadas que estão na produção agroecológica possuem experiência de aproximadamente 14 anos nesse modelo de agricultura. Os dados do campo de pesquisa também demonstram pelo menos outros três aspectos: i) diversidade produtiva; ii) carência de mão de obra; iii) alta demanda da produção. No que se referem aos consumidores, esses relataram que optam por alimentos agroecológicos, especialmente, em função da qualidade dos alimentos e da saúde familiar. Há também apontamentos relacionados quanto à demanda por produtos que atualmente não são produzidos de forma agroecológica. As considerações finais apontam para as potencialidades em termos de demanda, bem como os desafios colocados para expansão e consolidação da produção agroecológica no município.
