Tendances temporelles et caractéristiques des décès, des hospitalisations et des visites à l’urgence attribuables aux chutes chez les aînés au Canada
Authors: Yao Xiaoquan , Champagne André S. , McFaull Steven R. , Thompson Wendy
Published: November 2024

Les chutes chez les aînés (65 ans et plus) constituent un problème de santé publique au Canada. Les blessures liées aux chutes sont susceptibles d’entraîner une réduction de la qualité de vie chez les aînés ou de causer la mort. Elles entraînent également des coûts importants en matière de soins de santé. Il est essentiel de réaliser un suivi des blessures et des décès liés aux chutes chez les aînés afin de mieux en comprendre les tendances temporelles et les caractéristiques et d’évaluer les stratégies de prévention des chutes. Nous avons utilisé les plus récentes données de la Base canadienne de données de l’état civil – Décès, de la Base de données sur les congés des patients et du Système national d’information sur les soins ambulatoires pour analyser les tendances des décès, des hospitalisations et des visites à l’urgence liées aux chutes chez les aînés au Canada sur plus de dix ans. Nous avons également effectué une analyse en fonction de l’âge et du sexe. En 2022, dans l’ensemble du Canada (à l’exception du Yukon), 7 189 aînés sont décédés en raison d’une chute. Entre 2010 et 2022, de manière générale, le nombre et le taux de décès attribuables aux chutes ont augmenté. Au cours de l’exercice 2023-2024, il y a eu 81 599 hospitalisations liées aux chutes dans l’ensemble du Canada (à l’exception du Québec) et 212 570 visites à l’urgence liées aux chutes en Ontario et en Alberta. Entre 2010-2011 et 2023-2024, si la tendance générale des taux d’hospitalisation et de visite à l’urgence liées aux chutes n’a pas augmenté, leur nombre a généralement augmenté d’une année sur l’autre, sauf en 2020-2021, soit au début de la pandémie de COVID-19. En ce qui a trait à l’âge et au sexe, les taux de décès, d’hospitalisation et de visite à l’urgence ont augmenté avec l’âge à la fois chez les hommes et chez les femmes. Compte tenu du vieillissement de la population, la surveillance continue des tendances est essentielle pour la prévention des chutes.

Published: November 2024

The scientific article examines the institution of witness testimony in the process of investigating criminal offenses. A topical issue is the role of witnesses in criminal proceedings as a key source of information that can significantly influence the establishment of the truth.
The scientific article is devoted to the problems that arise when obtaining and using witness statements, in particular, their reliability and, accordingly, admissibility, the influence of external pressure and other participants in the proceedings or officials, as well as the possibility of distortion of information, unreliability of data.
Special attention is paid to the analysis of the legal confirmation of evidence in the protocol, which is important to ensure the acceptance of this evidence. The rights and obligations of the witness are investigated before the interrogation begins and such results are recorded in the protocol. An appropriate source of accurate recording of the testimony of a witness is audio recording or video recording, and the use of information technology during interrogation is a certain deterrent to the provision of reliable information by witnesses.
The testimony of persons in criminal proceedings is recorded in a protocol, which has the form defined by the criminal procedure law and is a mandatory document. In the interrogation protocol itself, it is indicated that the witness was warned about giving false testimony and refusing to testify. At the same time, witnesses have the right not to testify against their relatives. The interrogation protocol has a clearly defined structure, mandatory requisites for filling it out, during the interrogation the witness has the right to use the legal assistance of a lawyer.
An important procedural activity is the assessment of the credibility of witness statements and other procedural sources of evidence, which is carried out by the investigator, prosecutor, investigating judge, court on the basis of the law and within the limits of their procedural powers.
The main properties of the testimony of a witness, the totality of which forms the content of this type of evidence: the information is an oral or written message; the source of information is a person granted the procedural status of a witness; the information is important for this criminal proceeding; compliance with the requirements of the legislation is ensured when receiving and processing information.
Involvement of foreign judicial experts in criminal proceedings in the order of international cooperation

Published: November 2024

The article is devoted to the analysis of the norms of the criminal procedural legislation of Ukraine and other normative legal acts on the issues of forensic expert activity, which regulate the procedural mechanism of involving experts from other states who possess special knowledge and skills necessary to provide substantiated and objective written conclusions during pretrial investigation and trial.
Since the introduction of martial law in Ukraine in February 2022, the country has faced an urgent need to conduct an excessive number of forensic examinations in criminal proceedings related, in particular, to the identification of unidentified bodies and human remains. The scale of the tragedy required the involvement of foreign experts to conduct relevant research related to the development of DNA profiles of the victims and their relatives.
The article states that international cooperation during criminal proceedings includes, in addition to the fulfillment of requests for investigative (search) actions on the territory of other states in order to obtain evidence, the creation of joint investigative teams for the investigation of crimes, as well as the use of special knowledge in the form of forensic examinations.
It is concluded that the involvement of foreign experts in criminal proceedings in Ukraine in the order of international cooperation is provided for by the provisions of normative legal acts of a national nature, albeit in a rather general form. However, the procedural mechanism of involving experts and the order of international cooperation clearly need to be refined.
Based on the results of the analysis, the actual mechanisms for involving foreign experts in criminal proceedings, which are provided for by the Criminal Procedure Code of Ukraine and the Law of Ukraine «On Forensic Expertise», as well as existing gaps in the legislative regulation in this area, have been determined. Judicial practice also points to the possibility of involving specialists from other states for joint forensic examinations in criminal proceedings.
Some practical aspects of the implementation of the institute for advanced training of Ukrainian lawyers
Authors: Zaborovskyy V. V.
Published: November 2024

It is indicated that the procedure for improving the qualifications of lawyers provides for a rather voluminous list of possible types of raising their professional level, among which measures organized by the operators of improving the qualifications of lawyers occupy a decisive place, but also that a significant emphasis of such measures is aimed at ensuring the quality of their organization, in particular, by establishing essential professional, personal and ethical requirements for lecturers and their practical direction.
This article is aimed at revealing some practical aspects of the mechanism of the lawyer’s implementation of his professional duty to improve his qualifications. Thus, the scientific work reveals the essence of the ethical component as a necessary element of such a mechanism, and also analyzes the grounds for exempting a lawyer from the obligation to improve his qualifications.
Within the framework of this article, the legal regulation of the procedure for the lawyer to fulfill his duty to improve his qualifications was analyzed, namely through the prism of the need to master high standards of ethical behavior. Attention is drawn to the positivity of the provisions of the Ukrainian legislation, according to which a lawyer, improving his qualifications, must necessarily acquire a certain set of knowledge (in particular, concerning issues of lawyer ethics). This provision of domestic legislation generally corresponds to the legislation of many countries of the world (France, Italy, Norway, the Czech Republic, Ireland, etc.), especially in the context of professional development by lawyers who have just acquired this status (young lawyers).
It is concluded that the National Association of Lawyers of Ukraine needs to develop appropriate measures (programs) that would provide an opportunity to obtain an ethical component as a necessary condition for improving the qualifications of a lawyer on a free basis.
The legislation of foreign countries, which apply certain grounds for exemption from the obligation to improve the qualifications of lawyers, is also studied. The position is argued about the expediency of enshrining the provision according to which from the obligation to upgrade the qualifications not only of lawyers who have stopped their activities, lost their ability to work or have other good reasons, but also lawyers who have reached a certain age (for example, 65 years old), are engaged in the practice of law have been active for more than 30 years, or have a Doctor of Science degree and are recognized specialists in the field of law.

Authors: Dopilka V. O. , Balobanov O. O.
Published: November 2024

Today, in the global market of logistics services for the transportation of dangerous goods, there is a problem of balancing the commercial and safety conditions of these transportations.
The system of international regulation of the transportation of dangerous goods is quite complex and its regulatory legal support includes conventions and agreements. The current scheme of actions of the main conventions and agreements regulating the transportation of dangerous goods by various modes of transport was created by an international organization and must be implemented in national legislation. The system of international regulation of the transportation of dangerous goods is quite complex and its regulatory legal support includes many conventions and agreements. Scheme of actions of the main conventions and agreements regulating the transportation of dangerous goods by various types of transport, and international organizations that ensure their development and promote their implementation into regional norms and national transport legislation, outlined in this article. In the international plan, the main source of the regulatory framework in the field of transportation of dangerous goods by all types of transport are the UN Recommendations on the Transportation of Dangerous Goods (Model Rules).
The development of recommendations for the transportation of dangerous goods (Model Rules) is carried out by the Committee of Experts on the Transportation of Dangerous Goods in the globally agreed system of classification and labeling of chemical substances of the Economic and Social Council of the United Nations. On their basis, international organizations and national authorities of various countries are developing normative documents regulating the transportation of dangerous goods by various modes of transport, i.e., reflects the international legal basis, which should be implemented in national legislation. Today, the 18th edition of the Standard Rules for the Transportation of Dangerous Goods is in effect. Work on improving standards continues primarily because, according to UN data, the share of dangerous goods in world freight traffic is constantly growing and now reaches almost half of its total volume. The transportation of dangerous goods is associated with a significant potential for the occurrence of extraordinary events. There is an urgent need for measures to reduce this potential to the level of residual risks acceptable to society and the state.
Certain aspects of seizure and cancellation of property in criminal proceedings
Authors: Voronkin A. O.
Published: November 2024

The subject matter of this article is the analysis of the procedure for imposing and lifting the seizure of property in criminal proceedings, which is considered with due regard to the current provisions of the Criminal Procedure Code of Ukraine. Although the issue of seizure of property is given quite a lot of attention in the national doctrine of criminal procedure law, the author in the course of the analysis highlights the currently controversial provisions relating to the regulation of the procedure for imposing and revoking the seizure of property in criminal proceedings and analyzes the court’s conclusions regarding the interpretation of problematic issues in the course of law enforcement, and examines the general approaches to seizure of property in criminal proceedings through the prism of the European Court of Human Rights (hereinafter – ECHR) case law.
Among other things, the author examines the issues related to the procedural powers of special subjects of criminal proceedings (Director of the National Anti-Corruption Bureau of Ukraine/deputy Director, Director of the Bureau of Economic Security of Ukraine/deputy Director) in specific cases determined by the criminal procedure law.
At the same time, the author demonstrates that there are gaps in the current version of the Criminal Procedure Law in terms of regulating the powers of special subjects of criminal proceedings with regard to preliminary seizure of property without a court order, and also proposes amendments to the relevant article of the CPC of Ukraine with a view to bringing the provisions of the law in line with the general principles and purpose of criminal proceedings.
Particular emphasis is placed on the issues related to the imposition and cancellation of seizure of property of a third party whose property is being considered in criminal proceedings, the status of which is regulated by Article 642 of the CPC of Ukraine. The author proposes amendments and additions to the Criminal Procedure Code of Ukraine aimed at improving the procedures for seizure of property and ensuring the rights and legitimate interests of persons who do not have status in criminal proceedings and whose property becomes subject to seizure during the pre-trial investigation.
Some aspects of international cooperation and information exchange among journalists during armed conflicts: current challenges and prospects
Authors: Skutelnіk O. L.
Published: November 2024

The article examines the contemporary challenges of international journalism in the context of armed conflicts, particularly the war in Ukraine. It focuses on the risks to journalists’ safety, issues of censorship and information manipulation, as well as the impact of new technologies on the timeliness and accuracy of news. The study expands existing knowledge about international journalism by proposing a new model for analyzing the interaction of political, social, and technological factors in conflict situations.
Using a comprehensive case study methodology and bibliometric research, the article explores practical aspects of information exchange, including the creation of secure communication channels, adherence to ethical standards, and fact-checking. Content analysis of media messages and surveys of journalists working in conflict zones are employed in the research.
The study reveals that the war in Ukraine has led to a significant decline in international cooperation due to difficulties in ensuring the credibility of information, an increase in censorship and manipulation. Particularly pressing are the issues of journalists’ safety, restrictions on access to critical information sources, and challenges in maintaining media independence.
Additionally, the article highlights that armed conflicts pose numerous threats to journalists, such as risks of physical attacks, detention, and even life-threatening situations. In combat conditions, journalists often face restricted access to important information, complicating their work and impacting the quality of event coverage. These conditions necessitate new approaches to protecting journalists at both individual and institutional levels, as well as improving international safety standards and support.
The findings indicate the need to develop new strategies for protecting journalists, ensuring the accuracy of information, and strengthening international media cooperation. These conclusions have broad implications for understanding modern information wars and forming effective mechanisms to counter disinformation. The article makes a significant contribution to the advancement of journalism and may be useful for journalists, scholars, policymakers, and anyone interested in safeguarding freedom of speech and developing a democratic society.
Features of the functioning of the European Union institutional mechanism
Authors: Yudina H. I.
Published: November 2024

The institutional mechanism of the European Union remains an important object of research in connection with the constant evolution of integration processes and political challenges faced by the EU. In the conditions of globalization, economic crises and geopolitical instability, there is a need for a flexible and effective management system. However, despite significant achievements in the development of its institutions, the EU continues to face challenges related to the transparency of decision-making, the accountability of institutions and the proper representation of the interests of Union citizens. This is especially relevant against the background of the current debates on reforming the EU and improving its internal architecture.
The article focuses on analyzing the institutional mechanism of the European Union, its evolution, and the current challenges in ensuring the effective functioning of this supranational organization. The aim of the study is to examine the functioning of the EU’s institutional mechanism in terms of its ability to ensure coherence and efficiency in decision-making processes and the implementation of common policies. The research employed general scientific methods of cognition, such as analysis, synthesis, induction, deduction, and comparison. The study’s findings show that the institutional mechanism of the European Union is a complex, multi-level system that ensures the interaction of key institutions for the Union’s effective operation. The European Council performs a strategic role by determining the overall political directions of EU development. The European Commission carries out executive responsibilities and initiates legislative proposals, while the European Parliament and the Council of the EU jointly exercise legislative functions, emphasizing the equality of these institutions in decision-making. The Court of Justice of the European Union ensures compliance with legislation, providing legal oversight over the implementation of EU treaties and decisions, thereby guaranteeing the legal consistency of all institutions’ activities. The European Central Bank plays a key role in financial control, being responsible for monetary policy, while the Court of Auditors oversees the spending of the EU budget. The EU’s institutional system also includes numerous auxiliary bodies and agencies, such as the Committee of Permanent Representatives (COREPER), which plays a critical role in policy coordination between member states. These institutions provide multi-level cooperation between national governments and EU bodies, highlighting the Union’s supranational character and its integration processes.

Separate issues of forensic support for pretrial investigation of crimes committed in the field of defense procurement
Authors: Holubokyi T. S. , Hora I. V.
Published: November 2024

The article reveals the essence of forensic analysis of crimes in the field of defense procurement and the possibility of forensic support for their pre-trial investigation. The relevance of this problem is dictated by the fact that crimes in the field of defense procurement are an extremely dangerous destabilizing factor that negatively affects the combat capability of the Armed Forces and the defense capability of our state in the conditions of a full-scale war with an aggressor country. Particular attention is paid to the relationship between the elements of the forensic analysis of such criminally punishable acts and the criminal law. It is proved that this is quite natural as a result of the exclusive role of the criminal law in the construction of criminal offences. It is proved that this is quite natural as a result of the exclusive role of the criminal law in the construction of criminal offences. It is noted that the importance of defense procurement for the national security of the state leads to high requirements for the effectiveness of the investigation of crimes. In the system of countermeasures against such criminal manifestations, an important role is assigned to the legal and forensic support of law enforcement activities in this area.
In the criminalistics sense, the object of a crime in the field of defence procurement is a part of the material world to which a criminal act is directed, i.e. to take possession of what the criminal’s intention is aimed at or what harm is caused. It was determined that for the study of the subject of the criminalistics structure of this type of crime, his official functions are important. Possession of these or other official functions has a significant impact on the subject’s ability to influence the object of criminal encroachment, access to the means of committing a crime and the criminal’s choice of a set of these means, in other words, largely determines the mechanism of committing a crime. In order to form a forensic structure of crimes in the field of defence procurement, its elements and their interrelationships are defined. The content of such structural elements is given, which includes: the method of committing and concealing such crimes, the circumstances of the crime (place, time); typical traces of a crime, etc.
The article concludes that the quality of the pre-trial investigation of the specified types of crimes is directly dependent on the level of forensic support, including the availability of scientifically based recommendations for their detection and investigation, as well as on the appropriate forensic support.
Categorial-systemic analysis of F.M. Dostoevsky's personalism
Authors: Skosyreva A.S.
Published: November 2024

The article analyzes the philosophy of F. M. Dostoevsky's personalism as a system via the categorial-systemic methodology by V. I. Razumov. Dostoevsky's personalism is considered from the perspective of the researchers' interpretations of Dostoevsky's work by N. A. Berdyaev, M. M. Bakhtin, A. Z. Steinberg. We consider the contradiction between categories of individuality and unity of the people, as well as love and freedom in the philosophy of Dostoevsky's personalism. As a result of the analysis we conclude that harmonization of individuality is achieved through the dialectic of love and freedom.
Constructivism as the life world
Authors: Martynov V.A.
Published: November 2024

The inevitable consequence of the construction of the Wall between the word and the thing is a catastrophic impoverishment of the vital world. So, where all the words are simulacra, for the subject it is impossible to enjoy the consumption of things and qualities. In the beautiful new life world of modernity, creativity is impossible. The significance of intellectual work is diminished catastrophically. Impossible refusal, sacrifice. Impossible love (where two meet halfway through understanding). Nine-tenths of social life is closed to modern optics, the diversity of life is in the blind zone, appears dead and boring material. Accordingly, nine-tenths of people are also uninteresting. The life world of modern science is a world without people. But there are many violence. Declaring the infinity of nomadic freedom, modern knowledge builds a despotic hierarchy, dividing people into caste. This knowledge is a kind of utopia, projecting, typologically close to Bolshevism. The emergence of modern knowledge as a constructivist paradigm came to the point of obvious absurdity, not accidental, but embedded in the foundations of the paradigm itself.

Authors: Usov S.V.
Published: November 2024

In this paper the possibility of representing of some types of role-based access control models by object-oriented discretionary access control model is considered. The role-based security model without hierarchy and the role-based security model with hierarchy with inheritance "from above" are considered. The permissions of the role-based access control model are represented as a set of pairs of object and access right. A hierarchy of classes of the object-oriented HRU model based on the role-based access control policy is constructed. Commands of the object-oriented HRU model corresponding to the reassignment of roles in the original role-based model are described.
bH-BASES FOR A SOME CLASS OF FACET OF A CLIQUE PARTITIONING POLYTOPE

Published: November 2024

Let Kn=(V,E) be a complete undirected \protect\lb n-vertex graph without loops and multiple edges. A spanning subgraph H⊂Kn is called an M-graph if each of its connected components (possibly single-vertex) is a clique. In other words, every M-graph is a regular partition of Kn into vertex-disjoint cliques. The family of all M-graphs in Kn is denoted by H. This family is the set of feasible solutions to the clique partition problem, which consists in finding an M-graph of minimum weight \cite{GroWak1990,GroWak1989,SU1} in a complete edge-weighted graph. The mentioned works consider the polyhedral properties \cite{GroPad1985} of this problem, namely, they construct classes of inequalities generating faces of the problem polyhedron, on the basis of which branch and cut algorithms are developed. In this paper, using the technique proposed in \cite{Sim2017}, we prove the facet property of inequalities of a special class with respect to the polyhedron of the clique partition problem. \\\textit{This work was supported by the Russian Foundation for Basic Research (project 18-07-00599).}

Effect of Betel Lime (Ca(OH)₂) Concentration on the Physicochemical Characteristics of Sugar Palm Juice
Authors: Alan Sarsita Putra Yohanes , Putri Novita Ika , Pratiwi Alberta Rika , Ananingsih Victoria Kristina , Franz Nathan
Published: November 2024

Palm sap is a sugary liquid obtained from tapping palm trees, commonly used to produce various forms of palm sugar, including liquid, solid, and powdered. Reducing sugars, such as glucose and fructose, can inhibit crystallization by binding to sucrose crystals, resulting in smaller crystals and higher water content, which limits the production of molded or powdered sugar. To control reducing sugars, laru (a buffer and antimicrobial solution) is added to prevent their formation. However, in KUP Kadhang Maju, laru is sometimes ineffective in maintaining pH and preventing microbial contamination, affecting the quality of extracted sap for palm sugar production. This study aims to optimize the amount of betel lime (Ca(OH)₂) in laru to produce optimal palm sap. Three Ca(OH)₂-to-water ratios were tested, with sap collected from afternoon until the following morning. The analyses included pH, reducing sugar content, viscosity, total dissolved solids, and color intensity. Statistical tests included normality, homogeneity, One-way ANOVA, and Duncan's post hoc tests. The optimal treatment, P2 (2 grams of Ca(OH)₂ per liter of water), resulted in ideal sap for crystallization, with a pH of 6.50, reducing sugar content of 3.76%, viscosity of 35.50 cP, total dissolved solids at 12.17 °Brix, and color values L* 26.81, a* 3.53, and b* 7.81.

FoodCraft: Design of a precision agriculture system with IoT in indigenous communities in rural areas with diffi-cult Internet access in the department of Cauca-Colombia
Authors: Orozco Monje Juan Sebastián , Arce Santacruz José Javier , Cerón Rios Gineth Magaly
Published: November 2024

Nowadays, many countries have been implementing precision agricul-ture systems based on the Internet of Things (IoT) as they are useful tools to manage and monitor crop information for farmers. There is a wide diversity of approaches that help and facilitate producers to manage their agricultural land. IoT systems provide capabilities to adapt to the user's environment, for example by sensing data through wireless sensors or other devices. In agriculture, they can support the early detection of possible crop alterations and prevent production losses, thus improving the quantity and quality of the harvest, considering that each crop requires a personalized intervention. This research aims to propose an IoT system for the management and monitoring of the agricultural lands of the indigenous communities of Cauca, where Internet access is limited. The system adapts to the needs of the user, their agricultural and environmental information, time, location and traditional practices. This article introduces the IoT architec-ture and models, which were used to implement and test a prototype called Food-Craft. For the design of this system, there is satellite communication between IoT points with difficult access to the Internet. On the other hand, all sensor data is successfully received by the Arduino mega and sent to the database with the ESP8266 so that it can be accessed through the integrated Android app and web-site.

Authors: Mufarrege Tomás , Galíndez Vicente Martín , Zeballos Luis , Marcovecchio Marian G.
Published: November 2024

Las actividades fundamentales relacionadas con la logística en la gestión de residuos patológicos abarcan las operaciones seguras de recolección, transporte y descarga en los sitios destinados al tratamiento de estos materiales. La coordinación eficaz de los tiempos de estas operaciones resulta crucial para prevenir la propagación de enfermedades entre el personal de salud, los trabajadores encargados de la gestión y la comunidad en general. En este contexto, el presente trabajo propone una estrategia de resolución computacionalmente eficiente para abordar el desafío de la operación regular de recolección y transporte de residuos patológicos generados en instituciones de salud, como hospitales y sanatorios. El problema implica el ruteo de vehículos de tipo capacitado con viajes múltiples, clasificado como NP-hard en optimización combinatoria, en el cual se deben tener en cuentas restricciones particulares asociadas al manejo de residuos hospitalarios peligrosos. Dado que los métodos convencionales utilizados para resolver problemas de Programación Matemática Entera a menudo no logran encontrar una solución óptima en un tiempo de ejecución razonable, se hace evidente la necesidad de implementar técnicas específicas que permitan abordar eficientemente este problema. El trabajo aborda un caso real extraído de la literatura, proporcionando detalles sobre la metodología de resolución propuesta.

Published: November 2024

La agricultura de precisión supone la existencia de variabilidad espacial de la respuesta de los cultivos a la aplicación de insumos. Los experimentos a escala de lote permiten explorar dicha variabilidad. No obstante, la interacción entre la variabilidad espacial de los factores que controlan la respuesta del cultivo y el diseño experimental aplicado condicionan los resultados. Es necesario identificar diseños experimentales que optimicen la obtención de información fiable de la respuesta de los cultivos intra-lote. Se evaluaron diseños experimentales a escala de lote con distinta resolución espacial para estimar la variabilidad espacial de la respuesta de un cultivo a la aplicación de insumos. Se simularon patrones espaciales de respuesta como proceso subyacente para generar mapas de rendimiento. Mediante regresión ponderada geográficamente (GWR) se estimaron los patrones de respuesta del cultivo que se compararon con el campo estocástico subyacente. Los diseños con alta resolución espacial permiten capturar mejor los patrones de variabilidad espacial subyacente en un amplio rango de estructuras espaciales consideradas. A su vez, diseños en parcelas tipo tablero de ajedrez superan a los diseños en franjas ya que permiten detectar variabilidad espacial en ambas direcciones. No obstante, la concordancia entre los mapas de respuesta estimados por GWR y los de referencia son sensibles a la selección de kernel y ancho de banda.

Este trabajo presenta resultados del análisis de una experiencia de colaboración y coproducción de conocimientos entre la universidad y su entorno, motivada en el contexto de emergencia sanitaria por COVID-19. A través de la reconstrucción del recorrido institucional, organizacional y técnico para la producción de un ciclador para soporte respiratorio se analizan los factores claves que facilitan y obstaculizan su desarrollo, y definen las características de la coproducción de conocimientos en ese espacio de interacción, en el que participan una universidad nacional, un centro tecnológico y una empresa privada, entre otros actores. Estos procesos involucran dinámicas de interacción que implican estrategias, experiencias previas y saberes de los participantes, generando modificaciones en sus prácticas. Un hallazgo destacado es la influencia de la excepcionalidad de la emergencia sanitaria en la ruptura con los procesos tradicionales de vinculación universidad-entorno. Se destaca la formación de una amplia red de actores que colaboraron sin tener lazos previos, la rápida adaptación y modificación de procesos burocráticos y administrativos, y una ruptura con la lógica tradicional de relación entre la universidad y la empresa en cuanto al conocimiento. Se pone de manifiesto la singularidad y novedad de las experiencias durante la pandemia de COVID-19. Los resultados revelan la adaptación ágil de los participantes, la transformación de las prácticas institucionales y una mayor apertura hacia la colaboración interdisciplinaria y la transferencia acelerada de conocimientos y tecnologías. Estas experiencias excepcionales podrían tener implicaciones significativas en el futuro de la vinculación universidad-empresa, sugiriendo nuevas formas de colaboración y generando hipótesis para investigaciones futuras.

Este artigo tem como objetivo discutir o papel das redes sociais no processo de socialização do homem pós-moderno. Para isso, a fundamentação teórica é de natureza interdisciplinar e conta com trabalhos que versam sobre tecnologia e mídias digitais, bem como com pesquisas sobre os impactos sociais de uma era dita líquida. A metodologia é do tipo bibliográfico, partindo do princípio de que mobilizamos autores de diferentes áreas do conhecimento para complexificação do objetivo proposto. Os resultados revelam o desejo de necessidade do homem pós-moderno de construir narrativas falseadas nas redes sociais, de modo a tentar fazer com o que o outro crie uma determinada imagem de si.
Narrativas de pedagogas iniciantes

Published: November 2024

Este trabalho se inscreve em torno de narrativas de pedagogas iniciantes que, ao ensinar diferentes disciplinas nos anos iniciais do ensino fundamental, sentiram as dificuldades de viver a inserção profissional docente em tempos de pandemia e de ensinar em contexto de distanciamento e isolamento social. Na busca por uma construção de memórias e significados sobre a experiência do vivido, o objetivo do texto é discutir como professores/as iniciantes, licenciados/as em pedagogia e em situação de inserção profissional em turmas dos anos iniciais do ensino fundamental foram afetados/as pelo isolamento social e pela solidão docente durante a pandemia de COVID-19. O uso de ferramentas digitais viabilizou a realização de entrevistas com sete professoras licenciadas em pedagogia que atuavam nos anos iniciais do ensino fundamental, viviam o período de inserção docente em diferentes estados do Brasil e que participaram de uma pesquisa-formação interinstitucional. Teórico-metodologicamente orientou-se pela pesquisa narrativa, com base em Galvão e Clandinin e Connelly. As narrativas foram postas em diálogo teórico com Cruz, Farias e Hobold e Cochran-Smith no que se refere às especificidades da inserção profissional docente. Elas indicam que a pandemia exigiu diferentes modos de relação com/para o ensino, com as crianças e com os familiares, e trouxe o desafio de buscar estratégias pedagógicas virtuais com os/as estudantes e familiares, apesar dos afetamentos provocados pelos sentimentos de angústia, aflição e impotência que as acometeram durante o período. Conclui-se quanto à necessidade de políticas, programas e projetos de apoio e acompanhamento aos/às professores/as iniciantes em distintos contextos educacionais.

OBJECTIVE

To document objective metrics of attenuation of the pulmonary parenchyma on inspiratory and expiratory breath-hold CT in dogs with bronchomalacia (BM) and dogs without BM (NoBM) using automated software analysis. Metrics included mean lung attenuation, percent low-attenuation area at −856 HU, percent high-attenuation area at −700 HU, and percent attenuation area between −600 and −250 HU.

ANIMALS

Client-owned dogs with BM (n = 123) and NoBM (20).

METHODS

This retrospective study utilized 3D Slicer software (Brigham and Women's Hospital) to assess pulmonary CT attenuation. Analysis used Spearman correlation and 2-way ANOVA with beta regression.

RESULTS

Comparing the difference between inspiratory and expiratory phases, there was a significantly greater increase in mean lung attenuation (P = .001), a significant reduction in percent low-attenuation area at −856 HU (P = .016), and a significant increase in percent high-attenuation area at −700 HU and percent attenuation area between −600 and −250 HU (P < .001 and P < .0001, respectively) in BM versus NoBM dogs.

CONCLUSIONS

The higher inspiratory and expiratory difference in lung attenuation in BM compared to NoBM dogs supports the presence of impaired parenchymal aeration downstream of segmental and subsegmental airway collapse.

CLINICAL RELEVANCE

Quantitative image analysis holds promise for objectively evaluating changes with BM.
