Ovarian tissue transplantation makes it possible to restore fertility; however, the success of this technique depends on the transplant region used. Therefore, this study aimed to evaluate the effect of two subcutaneous regions on canine ovarian transplantation, pinna (Pi) and neck (Ne), for 7 and 15 days. Ovaries collected by ovariosalpingohysterectomy were fragmented using a punch device. Fresh fragments were fixed, and the others were immediately grafted onto the animal itself in the Pi and Ne regions for 7 and 15 days. Recovered fragments were evaluated for histology (morphology, development and stromal density), picrosirius (collagen fibers), and immunohistochemistry (fibrosis and cell proliferation). The results showed that follicular normality rates were lower in Pi-7 (78%) vs. control (90%) and Pi-15 (86%), similar in Ne-7 (92%) and superior in Ne-15 (97%) compared to the control, with the effect of the region Ne (94%) superior (P < 0.05) to Pi (82%). Stromal density reduced in both regions vs. control but was similar within 15 days. Fragments from both regions showed higher fibronectin labeling and deposition of type I and lower type III collagen fibers (P < 0.05) vs. control. Proliferation rates in Ne-7 were higher (P < 0.05) than in control, and Pi-15 was higher (P < 0.05) than Ne-15. In conclusion, the pinna can be a potential region for canine ovarian tissue autotransplantation than the neck region in 15 days.
Data Decomposition for Outlier Detection
Authors: Duari Gouranga , Kumar Rajeev
Published: February 2023

Decomposition for complexity minimization has long been a potent application, yet decomposition for outliers has rarely experimented. This paper presents a decomposition approach to detect local and global patterns of outliers in subgroups. The decomposition of the input data using K-means clustering makes homogeneous subgroups. Consequently, it reduces the complexity of data patterns by isolating possible outliers into the sub-groups. This approach creates clusters of homogeneous data points based on the fitness of purpose. They optimize the outlier patterns in the clusters for subsequent mapping of outlier detectors onto the clusters. This decomposition strategy is found to be effective in reducing the complexity of learning for the detectors without deterioration in the overall detection rate. We experimented with this approach on different benchmark data sets using different benchmark detectors. We observed that our data decomposition approach for outlier detection is superior for identifying localized patterns in the partitions and offers a better generalization.
Bildungsgerechtigkeit in einer digitalen Gesellschaft
Authors: Heinz Jana
Published: February 2023

bleiben auch in einer digitalen Gesellschaft bestehen und werden von neuen Ungleichheitsdimensionen überlagert. Digitale Kompetenzen, insbesondere die in einer digitalen Gesellschaft an Bedeutung gewinnenden Schlüsselkompetenzen, wie Kommunikation, Kreativität, Problemlösen und Kollaboration unterscheiden sich, wie auch analoge Kompetenzen je nach sozioökonomischer Herkunft der Kinder – und zwar zum Nachteil von Kindern aus weniger privilegierten Familien. Die soziale Herkunft beeinflusst zudem eine unterschiedliche Ausstattung mit digitalen Medien sowie die medialen Nutzungsmuster und den unterschiedlichen Nutzen, den Kinder aus der Verwendung digitaler Medien und sozialer Netzwerke für die Verfolgung eigener Ziele ziehen. Bildungsungleichheiten reproduzieren sich bei einem gleichzeitig gewachsenen problematisierenden Bewusstsein für die dahintersteckenden Ungerechtigkeiten auch in einer digitalen Gesellschaft. Dennoch ist bisher kaum untersucht, wie sich Bildungsungleichheiten in digitalen Gesellschaften darstellen. Um sich der Beantwortung dieser Frage zu nähern, werden zunächst wesentliche Diskursstränge zu Bildungsgerechtigkeit zusammengefasst. Im Anschluss wird definiert, was unter Digitalisierung als gesellschaftlicher Transformation verstanden wird, wie sich Digitalität, Bildung und Bildungsinstitutionen gegenseitig beeinflussen und schließlich, wie Bildungs(un)gerechtigkeiten in einer digitalen Gesellschaft adressiert werden können.
Im Ergebnis wird deutlich, dass Bildungsgerechtigkeit auch in einer digitalen Gesellschaft nur dann ermöglicht werden kann, wenn gerechte Zugangsschancen zum Kompetenzerwerb, insbesondere zum Erwerb von Schlüsselkompetenzen in Schulen hergestellt werden und vor allem Kinder aus weniger privilegierten Familien zusätzliche Unterstützung erhalten. Die Ermöglichung von Bildungsgerechtigkeit ist auch in einer digitalen Gesellschaft äußerst voraussetzungsvoll und benötigt Akteure, die für die Ursachen von Bildungsungleichheiten sensibilisiert sind. Weiterhin sind übergreifende gesellschaftliche Strukturen auf mehreren Ebenen notwendig, um Bildungsungleichheiten zu minimieren.
Determinants of external auditor selection and firm performance from a commercial bank manager’s perspective: Evidence from Vietnam
Authors: Nguyen Van Hau , Phan Thanh Hai , Ha Hai Giang
Published: February 2023

Financial statements of Vietnamese commercial banks must be audited annually by an auditing firm according to the Government’s regulations. This study identifies factors associated with firm performance and external audit selection. The decision to choose an auditing firm is considered an intermediate variable to determine the degree of impact of some factors on the performance of commercial banks. This study was conducted by interviewing 265 managers holding high positions as CEOs and CFOs at 30 commercial banks in Vietnam. The non-probability sampling method was applied. The survey was produced using Google Forms and sent directly to participants. Structural Equation Modeling (SEM) is applied to test hypotheses. The results show that except for the complexity of a firm, the factors such as legal environment, audit fees, audit firm size and reputation, bank governance, audit experience, and relationship positively impact external auditor selection. Besides, external auditor selection significantly affects firm performance. This study’s conclusions from the viewpoints of bank managers open the door to promising and timely future research. It is necessary to deepen and broaden academic understanding of the ideas and determining elements influencing external auditor selection and firm performance. More research is needed to fully comprehend this problem and move towards a policy solution.

A não-obrigatoriedade do ensino de Filosofia e a ideologia neoliberal: notas acerca de um retrocesso político e educacional
Authors: Ribeiro Jéssica
Published: February 2023

Este artigo visa discutir a medida tomada na Lei 13.415 de 2017 que retirou a obrigatoriedade da disciplina de Filosofia no ensino médio das escolas brasileiras. Parte-se do pressuposto que esta decisão não foi tomada de forma impensada, mas visando uma nova abordagem da educação e, consequentemente, da sociedade, tal qual ocorrido no período ditatorial no Brasil. Com o objetivo de obter uma classe trabalhadora especializada e sem formação intelectual e política, os cursos técnicos crescem enquanto os investimentos em educação pública de qualidade são esquecidos. Neste contexto, a Filosofia aparece como disciplina desnecessária e ferramenta perigosa, pois, ao permitir o pensamento autônomo, coloca em risco a manutenção de um governo baseado na alienação da população trabalhadora.
Introdução ao estudo da felicidade segundo Aristóteles
Authors: Barbosa Paulo Sérgio Cruz
Published: February 2023

RESUMO

O artigo trata de uma leitura introdutória sobre o estudo da felicidade na concepção de Aristóteles. Segundo o autor, a felicidade consiste em uma atividade da alma conforme a virtude. É o bem supremo, que tem um fim em si mesmo, sendo almejado por todos.  O que constitui a felicidade são as ações virtuosas, e as atividades viciosas conduzem o contrário. Em Ética a Nicômaco, percebe-se que uma atitude virtuosa parte de uma disposição de caráter que se relaciona com a escolha de ações diante das paixões, sendo consistente em uma mediania (meio-termo) que é determinada por um princípio racional próprio do homem dotado de sabedoria prática. A virtude, então, está para a felicidade, assim como a felicidade está para a virtude. Em A Politica, o filósofo destaca que o lugar mais propício para a efetivação da felicidade é a Cidade, e a maneira mais eficaz de praticá-la é através da consciência ética e da cidadania.

O trabalho se justifica pela importância de Foucault, pela relevância do conceito e pela aplicabilidade do tema para compreender situações cotidianas, como políticas públicas de saúde e controle do sexo. O texto é baseado em estudo bibliográfico. O manuscrito conclui que biopoder é um conceito atual, que ajuda a entender, por exemplo, as intervenções do poder político na saúde da população.
EDUCAÇÃO ENQUANTO DIREITO FUNDAMENTAL NO ESTADO DEMOCRÁTICO DE DIREITO BRASILEIRO
Authors: Lima de Matos Emilly , Damiani Nunes Ana Teresa
Published: February 2023

O Estado Democrático de Direito está alicerçado sobre os princípios da liberdade, legalidade e participação. No entanto, a efetividade deste é frequentemente questionada frente à realidade constatada no Brasil. O acesso à educação configura-se como um direito fundamental subjetivo que capacita o indivíduo a exercer sua cidadania e cobrar do poder público medidas efetivas em prol do bem estar de toda a população. O presente trabalho tem como objetivo refletir sobre o papel do Estado de Direito como promotor de educação democrática e de qualidade no Brasil. Quanto à metodologia, esse estudo pode ser classificado como qualitativa, do tipo explicativo. Em relação aos procedimentos, a pesquisa será de tipo bibliográfica, a partir de fontes primárias e secundárias compostas por documentos oficiais de órgãos nacionais e internacionais de acesso público e a revisão de arquivos de estudo presentes nos principais indexadores científicos por meio de levantamento de referências teóricas publicadas por meios escritos e eletrônicos, como livros, artigos científicos, páginas de web sites. O presente estudo mostra-se de suma relevância ao fornecer arcabouço para elaboração de políticas públicas que visem promover o acesso democrático à educação de qualidade. Observa-se que a educação se configura como um direito fundamental subjetivo resguardado pela Constituição. Entretanto, apesar da teoria e jurisprudência conclamarem o papel decisivo do Estado na promoção dos direitos fundamentais, no Brasil, ainda há um longo caminho a percorrer para a plena efetivação desses direitos.

Published: February 2023

This abstract is characterized as a research about a State of the Art whose purpose was to map the works focused on the theme of the student who emerges as a subject in his teaching-learning process. In this sense, we also aimed to contribute to the understanding of the importance of the school environment being considered and assumed as a locus that favors the production and expression of subjective meanings that constitute the teaching-learning process. For these purposes, research was carried out that subsidized us with regard to access to works in the area. The corpus of analysis considered in this research were the publications of 2011 and 2022, found among the works of the National Meeting of Encontro Nacional de Ensino, Pesquisa e Extensão (ENEPe), in the repository of the State Universidade Estadual de Goiás (UEG), in the repository of the Universidade de Brasília (UnB), and in the Google Scholar database. From our research, it was possible to organize the themes into categories: Subject and human relations in the classroom, Subject and creativity in learning, Social subjectivity and creativity in learning, Subject who learns, Subjective senses, Subjectivity and history of life, subjectivity and teaching through research. As a theoretical, methodological and epistemological basis, we use the guiding principles of Qualitative Epistemology, presiding over the cultural-historical perspective of subjectivity developed by González Rey. Regarding the conclusion, we could perceive ways that favored a favorable environment for the subject who learns and need for the production of more studies in this sense.
educação popular versus a escolarização
Authors: Lopes de Medeiros Dayane , Vieira de Melo Maria Aparecida
Published: February 2023

Resumo:  Este trabalho visa investigar e refletir a educação escolar, quanto a suas bases fundamentadoras e como estas propõem a organização da escolarização para o desenvolvimento do ser humano enquanto dotado de direitos equitativos e construtores de uma cidadania que valoriza o sujeito e não a “coisificação” do indivíduo como moeda de mercado. Se propõe pontuar a educação escolar em suas bases populares, pois uma educação popular vem de encontro para quebra necessária do sistema escolar que perpetua até os dias atuais no Brasil, encarcerando a população em uma condição de subserviência. Então, surge um questionamento: Como organizar uma educação escolar que abranja a educação popular como prioritária em seu sistema? Para responder a essa pergunta formam-se três vertentes direcionadoras: Pensar a educação a se construir; a forma como esta será organizada e sua finalidade; e os sujeitos que serão desenvolvidos, sua história, sua cultura e sua participação autônoma na organização do saber. Sendo uma pesquisa exploratória bibliográfica pondera sobre a escolarização versus a educação popular, abarcando diálogos e leituras realizadas nos encontros universitários e estágios realizados. A pesquisa foi realizada por meio da leitura sistemática de textos e produção de fichamentos com base em FREIRE, 1983; FREIRE, 1998; FREIRE, 2019; QUIHANO, 2005; IKEDA, 2010; GONZALEZ, 2020. Na busca por uma educação popular no seio escolar brasileiro, a pesquisa procura argumentar contra as bases eurocêntricas de ensino e como estas precisam ser reformuladas, trazendo ideias de como se deve trabalhar um ensinar para a tranquilidade, leveza, liberdade e felicidade dos alunos.
Polexit v. European Union

Published: February 2023

This article was based on the historical course of the Polish crisis that lasted more than 7 years, culminating with the ruling of October 7, 2021 by the Polish Constitutional Court. This, in turn, paved the way for Poland’s exit from the Union as well as the discussion of several open legal issues – from the rule of law and the Union’s values to the first considerations for the future of European integration.
The EU’s accession to the ECHR and the Dublin Regulation: is accession still desirable?
Authors: Gomes Beirão Joana
Published: February 2023

This paper addresses whether the European Union’s accession to the European Convention on Human Rights (ECHR) is still possible and desirable considering Opinion 2/13, as well as the caselaw of the Court of Justice of the European Union (CJEU) and the European Court of Human Rights (ECtHR) on the application of the Dublin Regulation. It argues that accession is still possible, though negotiations of an accession agreement compliant with the conditions imposed by Opinion 2/13 may prove particularly difficult in practice. Additionally, it argues that accession is desirable if the principle of mutual trust is not upheld over human rights, since accession in these conditions would enhance human rights protection in the context of the application of the Dublin Regulation.
Enforcing Environmental Policy – the role of the European Union
Authors: Guterres Iva
Published: February 2023

The concerns regarding climate change are on the top of government agendas worldwide, and a global response is urgently required given the climate events that countries all over the world are facing. The European Union (EU) is at the forefront, assuming the leadership in environmental policy with several legal initiatives underway, which have culminated in the promulgation of the European Climate Law and the presentation of the proposed Directive of a Carbon Border Adjustment Mechanism (CBAM). Nonetheless, the EU struggles with difficulties regarding the effectiveness of legal measures, in particular carbon leakage problems. Carbon leakage problems prevail globally as production shifts to countries with less stringent climate regulations, avoiding costs in countries with high emission charges. A resolution regarding the implementation of the CBAM was passed by the European Parliament in March 2021. On the 14th of July 2021, the EU presented 13 policy measures aiming to reduce its GHG emissions by 55% by 2030. On the 22nd of June 2022 the European Parliament voted to adopt the regulation about CBAM. As the EU has played a unique and strong role in climate policy enforcement, the aim of this article is to present this policy option, in the light of the oncoming CBAM. Therefore, the ‘EU climate club’ is imposing coercive environmental tax policies on other countries.

Published: February 2023

Based on numerical simulations carried out using numerical methods of continuum mechanics, the influence on the depth of craters, formed in steel barriers of various strengths, geometric and kinematic parameters of elongated cylindrical copper strikers, simulating elements of a cumulative jet, in the range from 0.3 to 8 km/s. For description the behavior of materials of the impactor and barrier, the model of a compressible elastic-plastic medium with a variable value of the yield strength. Determined that the classical hydrodynamic theory of the penetration of a cumulative jet into a barrier is not takes into account the effects of the inertial movement of the barrier after triggering separately taken element (aftereffect). The existence of three regimes is distinguished shock interaction-high-speed, when the elements behave like a liquid body, are worked out, but not inhibited; low speed, when the elements behave like solid body and are decelerated as a whole and intermediate, when the elements are decelerated and are deformed at the same time. It is shown that the braking mode of copper elements at high-speed impact on a steel armored barrier is realized at speeds smaller 0.8-1 km/s. It is shown that when interacting with an obstacle, high-speed fragmented cumulative jet, the total depth of armor penetration will be greater, than this is predicted by the classical hydrodynamic theory of penetration, and the more more, the higher the speed of the elements and the greater the distance between them on the one hand and less strength of the barrier on the other side. Keywords: High-velocity strike, elongated striker, cumulative jet, steel barrier, crater, inertial movement of the barrier, numerical modeling.

Authors: Tatarintsev A.A.  , Orlikovskiy N.A.  , Orlikovsaya N.G.  , Ozerova K.E.  , Shahova Y.E.
Published: February 2023

A method is proposed for measuring high-voltage charging potentials of dielectrics under ion irradiation by shifting the boundary of the bremsstrahlung X-ray spectrum. Since there is no bremsstrahlung output during Xe+ ion irradiation, it was proposed to use a probing electron beam to generate bremsstrahlung X-rays. To eliminate the effect of charge compensation on the surface, the value of the current of the probing probe of electrons was selected. The values of the equilibrium charging potentials of Al2O3 ceramics, Al2O3 sapphire, SiO2, and Teflon are obtained at different ion irradiation energies. The data obtained are compared with the results of spectrometric studies. Keywords: dielectric charging, ion irradiation, FIB-SEM, surface potential measurement.

A new method for synchrotron radiation x-ray imaging of micro-objects using nanofocusing optics and tomography
Authors: Kohn V. G.  , Argunova T. S.
Published: February 2023

A new absorption-based method for studying the internal structure of micro-objects using synchrotron radiation is proposed. The method registers the integral intensity of the beam after passing through the object, and the locality is achieved by focusing the beam with a refractive lens into a nanometer-wide line. In this case, phase contrast is not utilized, the result is obtained immediately, and two-dimensional images of an object are calculated by computed tomography. The method does not require complex mathematical calculations and gives high accuracy results. Model experiments using a silicon carbide substrate and some other parameters were performed for illustrative purposes. Keywords: Synchrotron Radiation, micro-objects, nanofocusing, tomography, micropores.

Collapsing Gunn Domains as a Mechanism of Self-Supporting Conducting State in Reversely Biased High-Voltage GaAs Diodes
Authors: Ivanov M. S.  , Rozhkov A. V.  , Rodin P. B.
Published: February 2023

Switching of a high-voltage GaAs diode to the conducting state in the delayed impact-ionization mode is simulated and the results are compared with experimental data. It is shown that the effect of long-term (up to 100 ns) sustaining of the conducting state of the diode after switching is due to the appearance of narrow (of the order of a micrometer) ionizing Gunn domains, the so-called collapsing domains, in the electron-hole plasma. Impact ionization in collapsing domains and in the edge (cathode and anode) domains of a strong electric field (~ 300 kV/cm) maintains a high concentration of nonequilibrium carriers (≥ 1017 cm-3) during the entire duration of the applied reverse polarity voltage pulse. Keywords: high-voltage GaAs diodes, impact ionization, subnanosecond switches, Gunn effect, lock-on effect.

Published: February 2023

En probióticos para avicultura es necesario evaluar estrategias de uso. El estudio evaluó el efecto del reemplazo progresivo del antibiótico promotor de crecimiento (APC) por probiótico sobre parámetros productivos, morfometría intestinal y ósea en broilers de 1 a 21 días. 200 pollos BB machos Cobb 500 fueron distribuidos en cuatro tratamientos con 10 repeticiones y cinco animales por repetición. Los tratamientos fueron: T1: dieta basal con bacitracina metileno disalicilato (BMD:500 ppm) por 1-21 días; T2: dieta basal con BMD (500 ppm) por 1-14 días y Enterococcus faecium (17,5 ppm) por 15-21 días; T3: dieta basal con BMD (500 ppm) por 1-7 días y Enterococcus faecium (17,5 ppm) por 8-21 días y T4: dieta basal con Enterococcus faecium (17,5 ppm) por 1-21 días. Se registraron parámetros de producción y el día 21 se sacrificaron dos animales por repetición para recolectar muestras de yeyuno y tibiotarsos. Los datos fueron analizados mediante DCA usando el procedimiento Anova y Tukey para comparación de medias. Los resultados mostraron que el peso vivo y la ganancia de peso fueron diferentes (p < 0,05) para T1 sobre T2; en morfometría intestinal, T4 tuvo mayor altura y área de vellosidad (p < 0,05) que T1, T2 y T3; en profundidad de cripta, T1 fue menor que otros tratamientos y en resistencia a fractura T4 fue mayor (p < 0,05). Se concluye que reemplazar APC por probióticos no presentó diferencias entre tratamientos y aquellos tratamientos exclusivamente con antibióticos o probióticos influyeron en morfometría intestinal y resistencia a fractura.

Materials and methods. Fifteen patients with FH included in the study were interviewed using an adapted Food Frequency Questionnaire. Their nutritional status was assessed with Anthro+ WHO software. The average daily intake of FETA nutrients and its possible correlation with other parameters were analyzed using SAS OnDemand for Academics software. Results. The results suggest a lack of complete dietary compliance in all age groups of patients. Patients with FH aged 5–9 years consumed more fat than recommended daily intake level. There was a significant deficit in vitamin D. Children with FH aged 10–14 years consumed less carbohydrates and fats per day, showed the deficiencies in protein, calcium, iron, iodine, zinc, vitamin D. Patients with FH aged 15–18 years had a slightly increased daily intake of cholesterol and vitamin D deficiency. This age group was the only to exceed the recommended daily cholesterol intake level. Age and gender had no effect on nutrient intake (p > 0.05). A statistically significant gender difference in intake of certain nutrients was recorded at ages 5–9 and 10–14 years only in the group of patients with FH, with higher levels in male patients. Conclusions. The diets of patients with FH and healthy children in all age groups were unbalanced, containing little protein and many non-recommended ingredients. Non-adherence to dietary treatment in patients with FH is associated with a lack of motivation, inadequate education of children and parents and a general lack of medical attention. Treatment of these patients requires a multidisciplinary team with a family-oriented approach that is focused on self-management skills development in a child. The FH management guidelines should include provision of medical nutrition therapy and step-by-step monitoring of growth and development.
The pathogenetic role of vitamin D and vitamin D-binding protein in the development of urinary tract infection in children
Authors: Lezhenko H.O. , Abaturov O.Ye. , Zakharchenko N.A.
Published: February 2023

Background. The aim of the research was to study the content of 1,25(OH)2D3 and vitamin D-binding protein (DBP) in the blood serum of children with urinary tract infections, taking into account the clinical form of the disease, and to determine their pathogenetic role in the development of urinary tract infections. Materials and methods. The study groups consisted of 84 children (mean age — 10.0 ± 1.3 years). The main group was divided into subgroups: the first one — 17 children with acute pyelonephritis, the second one — 21 patients with chronic pyelonephritis, the third one — 16 children with acute cystitis, the fourth one — 10 patients with unspecified urinary tract infections. The control group consisted of 20 relatively healthy children. The content of 1,25(OH)2D3 and DBP was investigated by immunoenzymatic analysis. Results. It was found that the development of the inflammatory process in the urinary tract was accompanied by a statistically significant (p < 0.01) decrease in the level of 1,25(OH)2D3 in the blood serum of the children of the main group compared to the controls. The level of 1,25(OH)2D3 in patients of all subgroups was significantly lower than that of the control group (p < 0.01), but there was no statistical difference between them. Serum level of DBP in the main group was statistically significantly (p < 0.05) increased compared to the controls, but we did not find a statistically significant difference between the subgroups studied. Conclusions. The development of an acute inflammatory process in the urinary tract in children occurs against the background of a statistically significant decrease in the blood level of 1,25(OH)2D3 combined with high levels of vitamin D-binding protein. This serves as a pathogenetic basis for the need to develop therapeutic and prophylactic schemes for prescribing vitamin D to children with urinary tract infections.
Diagnostic errors in neonatology
Authors: Mavropulo T.K. , Vlasov O.O. , Vereshchak O.Yu.
Published: February 2023

Background. Тhe incidence of diagnostic errors in neonatology and their impact on children’s health remain relatively unknown. The limited available evidence, however, suggests that diagnostic errors in the neonatal unit result in significant and long-term consequences. The purpose of the study was to generalize the literature data on diagnostic errors in neonatal units in view of their prevalence, impact on health status, and contributing factors. Materials and methods. The search was done in the PubMed Central® database using the keywords “misdiagnosis”, “diagnostic errors”, “neonatal intensive care unit”, “neonatal unit”, “neonatology”, “newborns”. Results. Methods to identify diagnostic errors were analyzed: autopsy results, consideration of complaints and conflicts, voluntary survey of doctors and patients, symptom-disease pair (SPADE approach), trigger methodology, Safer Dx Instrument (measurement and improvement of diagnostic safety). The incidence of detecting diagnosis errors ranged from 19.2 % when analyzing pathology studies (including 3.7 % of those that harmed a patient) to 6.2 % when using Safer Dx Instrument (including 8.0 % of those that that harmed a patient). A real assessment of this situation can be provided by a combination of the above methods. Conclusions. Further research is needed to better quantify misdiagnosis in neonatal intensive care units and to identify potential strategies to reduce its incidence or mitigate the harm associated with misdiagnosis.
Japanese Culture in the Modern History of Brazil
Authors: Yang Wang
Published: February 2023

Japan is an economic power, but also wants to be a political power. What will be the state of Japanese culture when it comes to the world? Brazil, home to the world’s largest Japanese diaspora, certainly provides us with plenty of realistic material and topics. The immigration from Japan to Brazil and the formation of the Japanese community is a major event and one of the important elements of the Japanese “participation in the new world”. For example, what role has Japanese culture played in Brazil’s modern history? How was Japanese culture transplanted and recreated by Japanese immigrants? It is of great significance and value to discuss this subject. In its century-long history, Japanese immigration has been a unique continuation. For the sake of convenience, this paper describes the evolution of Japanese culture in Brazil from the following four eras.
An Exploration of the AUKUS Trilateral Partnership
Authors: Ding Ran
Published: February 2023

On September 15, 2021, the US, UK, and Australia launched the Trilateral Security Partnership (AUKUS) in reaction to China’s increasing influence in the Indo-Pacific area. In reaction to China’s growth, this “small multilateral framework” based on “shared values” seeks to bolster US hegemony in the area by boosting military capability projection in the Indo-Pacific region. It is an example of the international nuclear non-proliferation system returning, which weakens it, causes disagreements among ASEAN nations, and upsets the balance of power in the Indo-Pacific area, all of which have a detrimental effect on the regional security situation. However, there are some fragile ties between the US and its allies, and the US-created AUKUS alliance’s prospects are dim given the lengthy and unpredictable time it takes for nuclear submarine cooperation to take hold.

Authors: Parguez Alain
Published: February 2023

El presente artículo tiene por objeto presentar la importancia de los bancos en la creación del dinero para satisfacer la liquidez de los empresarios. La comprensión entre el Modo de Producción Coercitivo y al Modo de Producción Monetario, así como las propiedades del dinero. La relación entre el Estado y el Empresario son claves en el desenvolvimiento del capitalismo. Al racionar el empleo, pueden atender su objetivo de ganancia, que explica por qué la tasa de interés no tiene efecto sobre la inversión. Lo calificado como «desintermediación» es, en verdad, una intermediación creciente, un alargamiento de la estructura monetaria.

"Exploring the Potential of Brain-Computer Interfaces in Managing Alzheimer\'s disease: A Review"
Authors: Kurup Aathira R , S Dr. Baulkani
Published: February 2023

Brain-computer interfaces (BCIs) have been proposed as a potential therapeutic tool for Alzheimer's disease patients. BCIs use electrodes placed on the scalp to record brain activity and translate it into control signals for a computer or other device. In Alzheimer's disease, BCIs have been shown to improve cognitive function and quality of life, particularly in the areas of memory, attention, and executive function. However, more research is needed to fully understand the potential benefits and limitations of BCIs for Alzheimer's patients.

Abstract: Sustainable development of a country or area requires availability of different resources and their efficient application. Water resources are one of the most valuable resources of a country. The proper use of water resources depends on appropriate management. Water supply management is a multifaceted approach, and an important affecting factor on this approach is the use of potential resources. Effluent reuse is proposed as an efficient solution to improve the management of water resources, particularly in developing countries such as India, where there is a Problem of water scarcity. Water stress has become a perennial concern in most Indian cities. The main Objective of the present study is to investigate requirements of sustainable development of water resources, especially in the case of wastewater recycling and upgrading of wastewater collection and treatment facilities. However, reuse of wastewater has many advantages that are discussed in the present study. Policies related to wastewater reclamation are more important in the Jammu & Kashmir, due to technologic, fundamental, and cultural limitations. These policies can have a significant impact on wastewater reclamation and water resources management.

Authors: Masekar Helli , Patel Shubham
Published: February 2023

Abstract: The NFT marketplace is a bustling arena, where individuals can buy, sell, and exchange Non-Fungible Tokens (NFTs). Much like a stock market, NFT marketplaces allow for the buying, selling, and trading of digital assets. In this research paper, we delve into uncharted territory by proposing a revolutionary approach to trading NFTs - the utilization of in-app coins, low gas fees, and a centralized network. We scrutinize the current NFT marketplace landscape, highlighting the most popular platforms and the dilemmas faced by users. Our research begins with a comprehensive overview of NFTs and how they differ from other fungible digital assets. We then present a novel method of trading NFTs, which utilizes in-app coins, aimed at improving the performance and usability of the marketplace. However, it is important to acknowledge that this new approach is not without its drawbacks, and we will examine them in detail. The implications of NFT marketplaces and digital ownership are far-reaching, encompassing both environmental and legal concerns. This research paper provides ideas applied in the use cases of industries towards innovative growth.
