Published: April 2022

The characteristics or properties that underlie the concept of community are present in several social groups which have some similarity in their distinctive features and they act as a core to the construction of the concepts of Domain, Discourse Community and Epistemic Community, which are fundamental to the research in several fields of knowledge. Considering the conceptual triangle – Domain, Discourse Community, and Epistemic Community - this study aims to examine theoretical and methodological aspects related to them by investigating their characterizing features and, consequently, their main distinctions and similarities, especially regarding the universe of Information Science. Thus, the aim of this essay is to contribute to the deepening of the theoretical understanding of the concepts covered, reflecting on their compatibilities, as well as the characteristics that distinguish and specify them.           It was possible to see that these concepts have similarities to each other, such as their contexts arising from the need to understand sociological aspects of science; the mutual understanding among its members about the specialized languages and theoretical bases used; the analysis based on tacit documents, duly expressed and recorded. These aspects of similarities demonstrate that these concepts can be understood as belonging to the same set, and inserted in the overarching area of Sociology of Science. Even so, these concepts have their characterizing features, which distinguish their analysis objectives and also their peculiar scientific biases.
Science, knowledge and society in times of pandemic:
Authors: Marteleto Regina Maria
Published: April 2022

This article deals with the new configurations of information and communication in the domain of health knowledge in Brazil, by the intercurrence of two concomitant factors: the increasingly powerful increment of technical mediations in the digital environment; the health crisis caused by the pandemic of the new coronavirus - the SARS-CoV-2. To study the domain at this critical moment, we considered the scientific society that represents it - the Brazilian Association of Collective Health (Abrasco) - and the way it promoted communication among peers in the scientific field and between them and society, through the "Abrasco Agoras", a set of webinars bringing together researchers, professionals, health authorities, representatives of organizations and social movements to discuss the issues related to the pandemic moment. We started with a theoretical treatment of Domain Analysis, to then approach the new modalities of scientific info-communication in the era of E-science and pandemic. The results of the analysis of a sample of the "Abrasco Agoras" show that the intensive use of digital devices and the accelerated rhythm of scientific knowledge production demand reflections on the health domain that take into account the very way of functioning of the scientific field, the status of researchers and health professionals, the processes of production, mediation, diffusion and appropriation of knowledge, the modes of information and communication among peers and between peers and society.

Compreende-se ao pesquisar acerca da biblioterapia e da mediação da leitura, que existe uma relação temática em que ambas favorecem a socialização e o equilíbrio emocional do sujeito por meio da leitura e dos benefícios que essa ação possibilita.  O objetivo deste estudo foi de evidenciar a inter-relação da biblioterapia com a mediação da leitura por meio das narrativas registradas nas entrevistas da Rede Mediar. Quanto à metodologia, trata-se de um estudo descritivo, para o qual foram adotados o método de estudo de caso e a abordagem qualitativa e foram analisadas as percepções compartilhadas por meio das entrevistas concedidas à Rede Mediar. Os resultados indicaram que a biblioterapia e a mediação da leitura se entrelaçam visando a um agir humanizador e consciente do mediador, para que ele apoie a formação e o desenvolvimento do sujeito na perspectiva leitora e o alcance do bem-estar. Considera-se que, na perspectiva da biblioterapia, o ato de ler tem uma intenção terapêutica que favorece mudanças singulares e sociais nos sujeitos.
Kantian ethics and African philosophy
Authors: AJEI Martin Odei , FLIKSCHUH Katrin A.
Published: April 2022

African philosophers have long engaged with Kant’s practical philosophy. Since the 1980s, much of this engagement has been with Kant’s anthropology of race and its role in the theoretical foundations of racism and European colonization. Our paper departs from this latter orientation by examining Ghanaian philosophical reflections on the Categorical Imperative, which Kant sets out as the supreme principle of practical reason. We assess this critique, and conclude that while the Ghanaian philosophers accept several aspects of Kantian ethics, they depart from Kant’s idealist metaphysics and associated dualistic conception of human nature. More specifically, while the Ghanaian philosophers accept Kant’s universalizability demands in relation to moral judgement, they also make a sustained case, contra Kant, in favour of the role of the emotions in moral motivation. The paper thus contributes to broader efforts underway to enrich the discourse on the reception of Kant’s philosophy in the global south.
clasificación y definición de las notas analíticas en las ideas de la Razón
Authors: HERNÁNDEZ Jassir
Published: April 2022

Los noumena son, en principio, conceptos límites. En el corpus kantiano encontramos múltiples de ellos, cuyo papel es decisivo en el tratamiento de la metafísica anterior, así como en la propuesta de metafísicas alternativas. Kant, sin embargo, no se detiene a explicarnos de dónde surgen esos conceptos y dónde irían. La presente investigación sugiere que a partir del concepto de nota (Merkmal) presentada en la KrV y desarrollada en la Jäsche Logik, podemos comprender estos noumena como las notas analíticas, suficientes, esenciales y primitivas de las ideas de la razón, tanto teóricas como prácticas.
Do Colonialismo ao Cosmopolitismo
Authors: SANTOS Leonel Ribeiro dos
Published: April 2022

Embora não seja documentável uma relação entre Kant e os pensadores ibéricos tardo-renascentistas e proto-modernos (tomados aqui coletivamente sob a designação de “Escola Ibérica da Paz”) por um conhecimento direto de fontes ou mesmo indireto de influências, todavia, algo do pensamento desses filósofos e teólogos ibéricos passou, pelo menos através do magistério e das obras de Francisco de Vitoria e de Francisco Suárez a alguns autores modernos, como Hugo Grócio e Samuel Pufendorf e, por estes, também a pensadores posteriores, nomeadamente, a Christian Wollf, Emmerich Vatel e Immanuel Kant. Assim, o que me proponho é identificar alguns tópicos que compõem a constelação do ius cosmopoliticum de Kant e reconhecer a sua correspondência com algumas das ideias dos pensadores ibéricos do tardio Renascimento e Proto-modernidade. A tese que proponho é que, com a sua ideia de ius cosmopoliticum, Kant recupera e desenvolve numa nova arquitetónica jurídica, o essencial daquilo que, naqueles pensadores, era entendido como sendo os inalienáveis direitos naturais dos homens, dos povos, da humanidade, os quais deviam inspirar todo o ordenamento jurídico-político, fosse no plano civil dentro de cada Estado, ou fosse no plano das relações internacionais entre Povos e Estados.

Con la situación de pandemia y cuarentena los cuidados tomaron una visibilidad y relevancia en la vida cotidiana y en la agenda de gobierno de nuestro país, la Argentina, nunca antes considerada como necesaria. Se ha puesto en evidencia cómo la organización social de los cuidados es injusta específicamente para las mujeres, dando cuenta de esta forma sobre su distribución desigual reproduciendo desigualdades e invisibilizando su valor. A partir de un análisis reflexivo de nuestra propia experiencia en pandemia como personas sexuadas, históricas, con deseos y afectos, con saberes situados de acuerdo a las enseñanzas de los feminismos, realizamos la presente comunicación focalizando en los trabajos domésticos y de cuidados que muestran una triple desigualdad: lo realizamos las mujeres, la mayoría luego de la jornada laboral que suele estar peor remunerada que la de los varones y sin remuneración alguna. La sobrecarga impacta en nuestra salud y desarrollo personal. Aún hoy, en todas las culturas, la esfera privada es el espacio de los desequilibrios e injusticias desde la división sexual del trabajo y los estereotipos culturales, siendo el núcleo más duro e invisible de la desigualdad de género. Es urgente la necesidad de revisar y repensar los roles familiares para promover la correspons
Fetal psychism: neurodynamic and psychoanalytic bases
Authors: Gomes Laurentino Silvia , Fiúza Boxwell Suzanal
Published: April 2022

Backgroung: Neuroscientific research has provided great discoveries regarding the understanding of the brain functioning and its neural circuits. With advances in studies on fetal behavior, new discussions have arisen about the existence of a possible rudimentary psychic apparatus. Questioning the existence of a psychism in the fetus becomes doubly challenging. First, because of the controversy that exists in the field of neuroscience about the studies of epiphenomena. Second, because of the difficulty that psychoanalysis has in accepting the existence of a psychic structure before birth. This study was carried out considering all these controversies and scientific limitations, and for this reason it should be understood as a theoretical hypothesis and an invitation to a broad and transdisciplinary view on the complexity of human behavior. From an extensive review on the development of the nervous system and fetal synaptogenesis, and combining neurophysiological and neurophysical research, it was possible to create a link with the Freudian theory of psychic energy described in the Project for a scientific psychology. From these joints, questions were raised about fetal development, especially in the preterm phase, which would be composed of intense synaptic activities, especially in the somatosensory and thalamocortical regions that would receive exogenous and endogenous stimuli, both acting to generate an accumulation of psychic energy. Thus, it was hypothesized that this intense flow of energy would be the first sign of the development of the primitive psychic apparatus in the fetus. Thus, it was possible to assume that during the preterm period this cathected energy discharge could project directly onto the limbic and motor brain structures and leave unconscious memory traces of intrauterine life experiences. These influences of a psychic nature, together with epigenetic factors, would contribute to the appearance of certain behavioral and neurodevelopmental disorders. Therefore, suggesting an early transdisciplinary approach in at-risk infants exposed to environmental or epigenetic stressors during the gestational period, especially during the synaptic plasticity window, will provide a therapeutic opportunity through psychic reorganization and sensorimotor integration.

Published: April 2022

Background: Camels' urine has been utilized for therapeutic purposes and anecdotally hailed as a treatment for a variety of ailments for millennia. The purported medicinal effects of camel urine, on the other hand, have yet to be thoroughly investigated and it has not been verified whether it is free of bacteria dangerous to human health. The common practice of using camel urine as a therapeutic agent in the Taif region of Saudi Arabia may pose health risks. This study examines the distribution of urine microbiota in camels and effect of the type of nutrition on microbiota. Material and methods: Therefore, 80 camel urine samples were collected from 6 different stations in this region. Urine was collected from healthy male and female (pregnant ,mother ) camels aged 1–8 years .The camels were divided into two groups with a different natural feeding pattern G1:which grazes naturally on wild plants ( wild feeding)&G2: which grazes naturally on wild plants, fodder and barley(mixed feeding). The 16S rRNA gene of the bacteria will be sequenced to the identify of bacteria isolated from camel urine. Finding a relationship between the urine microbiota and the mode of nutrition by profiling the bacterial species in both groups. Results: 16S rRNA gene sequence analysis showed that most of the isolates were Bacillus velezensis and Bacillus tropicus, constituting 42 % and 15 % of the samples, respectively. Surprisingly, these bacterial species have an antimicrobial effect. This may explain the role of camel urine as an antimicrobial. The comparative 16SrRNA Sequencing revealed significant differences in the urine microbiota between the two groups. This indicates the effect of the camel's diet on the microbiota of camel urine.
Inheritance of Leaf and Seed Yield in F1 Hybrids of Different Types of Tobacco (Nicotiana tabacum L.)
Authors: Aleksoski Jane
Published: April 2022

The paper studies four F1 hybrids obtained by crossing five parental genotypes, four of which are oriental in the role of mother (three of the Prilep type: P-23, P 18-50/4, P 76/86, and one of the Basmak type - MS 8/1) and a large-leaf Burley type (B-1/91) in the role of father, for the traits: yield of green leaf mass per stalk and per hectare, yield of dry leaf mass per stalk and per hectare and yield of seed per plant and per hectare. The experiment was placed on the experimental field at the Scientific Tobacco Institute - Prilep by Random block system in four repetitions for the vegetative period et 2019 and 2020. All appropriate cultural practices were applied during the growing season. The aim of this work was to study the mode of inheritance of stated agronomic traits, to detect heterosis in F1 generation and assess its economic viability. The most common mode of inheritance for the agronomic properties in the F1 generation is the intermediate, then the partial-dominant. In the inheritance of the yield of green and dry leaf mass per stalk, in the two years of investigation there is no occurrence of heterosis, while in the inheritance of the seed yield per plant in all combinations there is the occurrence of positive heterosis. The highest heterotic effect has MS 8/1 x B-9/91. In analyzing the yield of green and dry leaf mass and seeds in tons per hectare, a different vision was obtained, because the calculations are made at different planting distances of genotypes. Thus, for the yield of green leaf higher value than the more productive parent showed P 76/86 x B-9/91, while for the yield of dry leaf higher values than the more productive parents showed P 18-50/4 x B-9/91 and P 76/86 x B-9/91. In terms of seed yield per hectare, hybrids did not exceed the parents. The mode of inheritance of the agronomic traits per stalk indicates a shorter and more reliable successive period of time in the selection activity for the creation of new, superior varieties of toba

Published: April 2022

Article 88 of Law Number 19 of 2003 jo. SOE Minister Regulation Number PER-02/MBU/7/2017 stipulates that BUMN companies (State Owned Enterprises) are required to implement PKBL (Partnership and Community Development Programs). The obligation to implement PKBL is basically intended to be able to contribute in the effort to empower micro and small businesses in Indonesia. This study discusses the effectiveness of the implementation of PKBL at PT Jasa Raharja (Persero) Lampung Branch and the obstacles faced in implementing PKBL in an effort to empower micro and small businesses in Lampung. This research is an empirical normative legal research with a descriptive type of research as well as an applied normative approach (applied law approach). The results of the study indicate that in the context of empowering micro and small businesses, PT Jasa Raharja (Persero) Lampung Branch has implemented a Partnership Program (PK) which is distributed in 2 (two) forms, namely loans to finance business capital and guidance to fostered partners. Meanwhile, the Community Development Program (PBL) has also been implemented and distributed in 3 (three) forms, namely in the fields of education and training, community social assistance, and worship facilities. In the implementation of PKBL, obstacles were found, namely the problem of refunding funds from several fostered partners that were not smooth. Another obstacle is the distance between the place of business or the location of the program which is quite far from the office of PT Jasa Raharja (Persero) Lampung Branch so that it results in not being able to optimally carry out field surveys or provide guidance to each fostered partner or to all fostered partners.

Published: April 2022

The most common surgical emergency encountered during pregnancy is acute appendicitis [1]. The diagnosis of acute appendicitis during pregnancy is often challenging mainly because of physiological and anatomical changes during pregnancy. From a therapeutic point of view, the approach depends on the gestational age and the evolutionary stage of the appendicitis. The maternal-fetal prognosis depends on the severity of the condition and the delay in treatment. Appendectomy should be performed in patients presenting a highly suggestive clinical and ultrasonographic picture, preferably by laparoscopy in order to avoid more severe complications which could be life-threatening for the mother or infant.
