Rolle und Rechte der Fans bei Sportübertragungen
Authors: Dohmen Christian
Published: November 2024

Contrary to the usual assertion ("broadcasting rights"), sporting events do not "belong" to sports organizers in the sense of a legal right. The despite being strictly disadvantageous for the fans long since customary joint and exclusive sale of so called "broadcasting rights" violates antitrust law. This is because if they are allowed to broadcast the respective sporting events exclusively, broadcasters do not compete, but operate on separate end consumer markets, which they dominate because of their exclusivity. This foreclosure of respectively elimination of competition on the end consumer markets must no longer be tolerated by the antitrust authorities.
Sepsis-Induced Coagulopathy: From Pathophysiology to Patient Care
Authors: Balal Abdelrahman , M. Obeidat Ahmad , Y. Fadul Khalid , Sati Wala , M.I. Ahmed Sara , Elgassim Mohamed , Nahid Seema
Published: November 2024

Sepsis is a potentially life-threatening complication of infection, leading to sequential events that can result in widespread organ dysfunction. Sepsis triggers strong activation of the coagulation system and its regulatory cells, resulting in a wide spectrum of hemostatic abnormalities, ranging from subclinical activation of coagulation and hypercoagulability to sustained systemic clotting activation leading to consumption of clotting factors and platelets and the development of overt DIC. SIC is a major complication of sepsis, and it represents a variant of non-overt DIC that involves intravascular coagulation induced by inflammatory-mediated TF expression and is associated with an increased risk of thrombosis, worsening organ dysfunction, and increased mortality. The pathogenesis of SIC is multifactorial. Contributors include hyperinflammation, dysregulated immune response, and altered coagulation. The dysregulated coagulation activation, disruption of the body’s natural anticoagulant systems, and impairment of fibrinolysis represent a basic pathogenic process that drives the emergence of coagulopathy in sepsis. Treatment of DIC depends on treating the underlying condition. Early goal-directed therapy is essential to avoid morbidity and mortality. The considered use of blood component therapy, alongside prompt management of the underlying infectious source, may represent a reasonable therapeutic approach for improving outcomes in these high-risk patients.

DNA Replication Stress and the Human Genome: Hurdles, Hijacks and Cell Health
Authors: Teotia Varsha , Pantuczek Jessica , Bashir Valiya Kalladi Waseem , J. Murphy John , Surendranath Kalpana
Published: November 2024

During replication of the genetic material, cells often face hurdles that challenge DNA replication machinery, leading to replication stress. Multiple complex signalling pathways have evolved to counteract and overcome such challenges. However, DNA repair defects caused by inefficient functioning of the DNA damage response pathways (DDR) drive genomic instability, one of the hallmarks of cancer. Here, we review the known events in DNA replication that induce replication stress and the mechanisms deployed by DDR pathways to deal with and overcome replication stress. Since the defects in these molecular pathways are associated with tumour progression, we provide an update on the novel and promising druggable targets emerging from DDR pathways. Further, we discuss how viruses replicate their DNA by hijacking and exploiting the DDR pathways and the potential to target replication stress-associated molecules for the identification of new anticancer molecules.
Perspective Chapter: Climate Change Adaptation Strategies for Sustainable Water Resources in Iraq
Authors: H. Saeed Fouad
Published: November 2024

In the past few years, the adverse effects of climate change on the water resources of Iraq become significant. The observation indicated an increase in the frequency and intensity of extreme climate events. Scientific pieces of evidence showed that water resources in Iraq declined and more decrease is expected in the future due to reduced precipitation and evaporation rate rise. Water demands have also increased as a consequence of these effects. Climate change and population growth impose adaptation plans in all consumed sectors, these plans involve the balancing of water resources and water demands to prevent water stress and support sustainability. The adaptation strategy involved improving irrigation system efficiency, water use pricing, water meter installation, enhancing urban water network, institutional and legal changes and efficient water management plans that could support water and food securities increase resilience and reduce vulnerability. The adaptation plans should be implemented in ascending manners on the time horizon to eliminate adaptation barriers, as the negative impact of climate change increases with time. Modern adaptation options are beneficial to implement smart agriculture, crop genetic engineering, micro-irrigation and drought-resistant crops.

"Spaziergänge im Zick-Zack" : Paul Leppin im Feuilleton der Prager Zeitschrift Die Wahrheit
Authors: Zbytovský Štěpán
Published: November 2024

The article provides an overview of the journalistic activities of the Prague-based German writer Paul Leppin for the magazine Die Warheit, which in 1925-1933 was one of Leppin's main publishing platforms. More in-depth attention is paid to the author’s general theses on art, Czech-German relations and his own attitude towards the Czechoslovak Republic, reviews of German writers from the Czech lands and film criticism. These aspects of Leppin's journalistic work for Die Wahrheit are complemented by insights into the contexts of literary and cultural-political discussions and events. The author’s self-stylization as a unique witness to old Prague, his specific interest in the moral dimension of art, and his defense of kitsch filmmaking at a time of economic and political crisis in Europe are highlighted.
Die pragmatische Wende und ihre Folgen für die Fremdsprachendidaktik
Authors: Frydrychová Andrea
Published: November 2024

This article explores the question of how the so-called pragmatic turn in linguistics has shaped foreign language didactics. In doing so, sub-areas of pragmatics as well as foreign language didactics are taken up terminologically. After presenting the theoretical foundations of the sub-disciplines of linguistics and foreign language didactics, it is shown how the aforementioned academic disciplines can be interlinked, which is of central interest for this text. The reflection focuses on the area of the pragmatic turn, which was an important point for the reorientation of linguistic research in the second half of the 20th century.
Za co vděčí environmentální výchova Haně Librové
Authors: Máchal Aleš
Published: November 2024

Between 1992–2002 in particular, the conditions for establishing and improving the quality of environmental education in the Czech Republic were not optimal. Many politicians, school officials, and even some school principals, at best did not take this newly emerging field of pedagogy seriously. At worst, they tried to oppose or even suppress it. All the more important, for the workers of environmental education centers and similarly committed teachers, were the ideas and arguments defending the meaningfulness of eco-pedagogical action. Among the open supporters of the field, Professor Hana Librová took the most prominent place with her articles, books and lectures. The contribution presented contains a selection of her texts from a time when our field needed and appreciated them the most.
Post-růst
Authors: Moldan Bedřich
Published: November 2024

We are living in a new epoch called the Anthropocene, where man-made forces equal natural forces shaping the whole planet Earth. It brings spectacular economic achievements and improved standard of living, but, on the other hand, we witness grave global ecological deterioration, e.g. climate, biodiversity and pollution crises. The ultimate cause of these crises is economic growth. Sustainable development and green growth are presented as solutions, but these responses are not still entirely satisfactory. Degrowth and postgrowth conceptions are bringing new useful ideas, but the discussion is still ongoing and much further work is needed.

Published: November 2024

The book is a tribute to Professor Hana Librová on the occasion of her 80th birthday. The chapters have been written by her colleagues from the Department of Environmental Studies and other related departments, as well as by her friends from the environmental movement. Each of the co-authors has attempted to build on Hana Librová’s work – some have directly engaged in polemical discussions with it, others have taken it as an opportunity to reflect on a topic they have long been involved in. All of the authors wanted to try to imitate Hana Librová’s style in such a way that the resulting texts would be accessible to readers outside the academic community, while maintaining a scientific rigour when pursuing this goal. Readers can look forward to nine partial studies that thematically relate to different aspects of Hana Librová’s work. Some of the chapters turn their attention to the themes of her earlier historical-cultural texts looking at the landscape. Elsewhere, authors have drawn from the rich store of her journalistic articles. Others have followed on from research into lifestyles or have broadened the field of vision to include systemic, especially economic and political, issues. Taken as a whole, the book shows that any evaluation of Hana Librová’s lifetime work certainly does not have to be based on referring to the past. The book can be seen as proof of the immense inspiration that Hana Librová’s intellectual achievements have provided – and which will certainly continue to do so in the future.
Developing Ethical Principles from Indigenous Moral Values
Authors: Akintona Emmanuel Ola , Oluwadolapo Daramola
Published: November 2024

Moral decadence has reached an alarming stage in Nigeria to the extent that people now freely engage in all sorts of anti-social behaviours detrimental to national development. Westernization has been conflated with civility and modernity, and African traditional moral values reduced to nothing. The adoption of Western ethical principles as ideals, and the abandonment of African indigenous moral values have done more harm than good to our national development. This paper adopts a critical and conceptual analytic method to address the problem of moral decadence in Nigeria which has eaten deep into the moral fabric of the nation. Indigenous African moral values place emphasis on good character. A good man is a man of good character who refrains from vices and cultivates virtues. African indigenous moral values are preserved in folktales, proverbs, sayings of sages, etiquette and taboos. Individualism is abhorrent to African mentality while family-hood, brotherliness and communalism are the pivot of her moral value system. The fact that Western ethical principles emphasize individualism makes them largely unsuitable for the African mental setting which is mainly communalism. The paper concludes that developing ethical principles from African indigenous moral values and reintegrating them into her value system will go a long way in solving the problem of moral decadence in Nigeria.
Teaching Moral Character and Virtues at Pre-tertiary Levels: An Ibibio Virtue Ethics Approach
Authors: Okpo Odumayak
Published: November 2024

No nation can experience authentic or sustainable development without a quality education of its citizens. A quality education involves both the intellectual and moral character development of the human person. The need for moral character curriculum in our schools lies in the moral crises found in our society today. The Nigerian society is permeated with corruption, examination malpractices, dishonesty, fraud, selfishness and other immoral acts. We have lost our moral compass and we see this among politicians, doctors, teachers, pastors, Imams, and security personnel among others. The aim of this paper is to recommend and examine the place of moral character and virtues in the education of young people today, and in society at large. The Ibibio virtue ethics was employed to achieve the aim of this paper. Ibibio morality is summed up by the word Edu (character). Edu is the overriding trait of a person’s life. It is that which distinguishes a virtuous individual from a vicious one in the Ibibio society. Hence, a person with good moral character is one that acts, behaves, and conducts him/herself in accordance with the positive and negative virtues or one that demonstrates virtuous acts. This paper recommends the introduction and teaching of moral character and virtues embedded in the Ibibio virtue ethics to children at the pre-tertiary level of our educational institutions.
Character Formation in Nigeria: Lessons from Virtue Ethics in Esan Ontology
Authors: Ehiakhamen Justina O.
Published: November 2024

The quest for character formation through the teaching of virtue ethics as embedded in Esan ontology implies a conviction that virtue is fast being eroding from the Nigerian society of today. The reason for this may not be unconnected with the advent of European colonialism, modernity and inadequate curriculum in our educational systems, with its value deficit. The implications of a morally failed society manifest in an unprecedented crimes and criminal activities warring against meaningful development and social cohesion. This paper proposes the view that the teaching of virtue ethics at the primary and secondary school levels is imperative for the regeneration of formidable virtues and excellent moral character in the youths. Our consideration is an extraction from Esan ontology which kept the traditional people together as one indivisible entity. The method of exposition and analysis will help us to achieve our aim in this study.
Yoruba Concept of Iwa L’ewa as a Tool for Shaping the Moral Character of the Nigerian Child
Authors: Adegoke Aduragbemi Isaac
Published: November 2024

Moral character education is one of those major yardsticks for measuring beauty in an individual in the Yoruba society. This seems to be lacking in the Nigerian society today because more emphasis is being placed on the outward and or physical manifestations of beauty. The Yoruba holds that beauty consists of two variables which are ewa (outer beauty, exterior aesthetics) and iwa (inner beauty, interior aesthetics). It is argued that the Yoruba do not take any of the concepts in isolation but treat them as two sides of the same coin, although emphasis is placed on iwa. Until there is a synthesis of both iwa and ewa which is encapsulated in i wal ’ewa an individual is short of a person. This paper urges for the teaching of the Yoruba concept of beauty in the upbringing of the Nigerian child for it will ultimately result in the development of citizens who have the interest of the nation at heart and not their own selfish desires with corruptive tendencies.
An Inquiry into the Metaphysico-Ethical Foundation of Adekunle Ajasin’s Conception of Education
Authors: Itanrin Sylvester L. Dada
Published: November 2024

Michael Adekunle Ajasin is a primal sage, frontline educationist, moral philosopher and a transformational leader. As a social reformer, he possesses stubborn adherence to all that is noble, respectable, dignifying, ethically auspicious and morally unassailable. Ajasin’s philosophy of education integrates a body of thought-patterns that includes a theory of education, a theory of ethics and aesthetics, a theory of metaphysics, and an epistemological orientation that draws extensively from the culture and sociology of the environment. Ajasin fervently believes that a fundamental goal of education is to train individuals to radiate their inner beauty and talents through the acquisition of skills. Through the pursuit of these virtuous qualities, character and competence become interwoven for societal transformation. Thus, Ajasin’s conception of education contains elements of essentialism and Reconstructionism. For Ajasin, the teacher is a symbol of social reform, an ambassador of culture and a propagator of virtue. This being so, education aims at the inculcation of those essentials that would bring about social reforms, making education a national project targeted at nation building and national development.
A Perényiek nyalábvári reneszánsz központja
Authors:   Ferenc Rakoczi II Transcarpathian Hungarian College of Higher Education, Kész Margit , Kész Barnabás ,   Ferenc Rakoczi II Transcarpathian Hungarian College of Higher Education
Published: November 2024

The Ugocsa estates of the Perényi family, Korolevo and the castle of Nyaláb, became Renaissance monuments of national importance in the 16th century. The era was defined by ominous events: the Dózsa Rebellion, the invasion of Ottoman Turks, and the country’s division into three parts. As a result of political events, manorial centres on the periphery of the Kingdom of Hungary paradoxically sometimes had more opportunities for development than the central areas of the country. The battles raged, but the wealthy Perényi family, which gained national influence and played a decisive role in the north-eastern counties, donated to literature and art because they wanted to develop the Hungarian language. It was important for them to be the first ones to read the letters of Saint Paul in print in their native language; they encouraged and sponsored the publication of Benedek Komjáthy’s Bible translation; and they supported the intellectual activity of the first Reformers. In addition, the traveling singer Péter Ilosvai Selymes also started and finished his career with them, and even Bálint Balassi was connected to the Perényi family. Support for the publication of psalms, religious songs, secular poems, and stories is connected to the family. In addition to the men of outstanding individuality and charity (Gábor Perényi, János P., István P., etc.), there was the caring mother, a woman who also dealt with economic matters in her widowhood: Katalin P. Frangepán. In addition to supporting literature, the activities of this noble family in supporting the fine arts cannot be neglected either. Stone carvings and stove tiles with the Perényi coat of arms or Renaissance flower motifs made in the castle of Nyaláb can be compared to the works of art in Sárospatak and elsewhere. Thanks to the activities of the Perényi family who donated to art and science and tolerated the culture of other ethnicities in addition to the Hungarian, such unique spiritual treasures as, for example, the Gospel of Korolevo – one of the oldest written records of Transcarpathia and Ukraine, were able to survive to this day. It can be said that Korolevo and the castle of Nyaláb became one of the cradles of Hungarian literature born at the beginning of the 16th century during the time of the Perényi family.

Comprehensive Survey of Image Steganography Systems based on FPGA Implementation
Authors: Al-Ashwal Ali Y. , Al-Arashi Waled Hussein , Saad Abdul-Malik H. Y. , Al-Shadadi Mohammed M.
Published: November 2024

Steganography is the art of concealed communication. The basic idea of steganography is to hide secret data inside a cover media in an undetectable manner. Cover media and Secret data can be any popular digital media such as image, video, audio, or text. Various types of image steganography methods have been proposed according to the cover image domain, i.e. spatial domain and transform domain. The spatial domain methods are easy and simple while the transform domain methods are more complex. However, the transform domain methods are more robust against image processing operations. Besides, they are more secure and less detectable in an unsecured channel. The recent steganography methods are based on sophisticated algorithms that include several computational time-consuming tasks, and hence they are unable to embed and extract the hidden data in real-time. Therefore, the trend is to implement the steganography methods in the hardware to speed up their processing time and so improves the efficacy of steganography techniques. FPGA is used in various fields in the modern era due to lower development cost, flexibility, and reconfigurability. Most of the published steganography techniques carried out on FPGA are based on the spatial domain. In this paper, it has comprehensively studied and reviewed various existing implementations of image steganography on FPGAs. This includes studying their general operations, requirements, and performance evaluations. This review would assist researchers in finding the research gaps in FPGA implementation of steganography methods for real-time applications.

Aerographite: a Candidate Material for Interstellar Photon Sailing
Authors:   Physics Dept., New York City College of Technology, Matloff Gregory L.
Published: November 2024

Aerographite has been suggested in a recent paper as a possible candidate for interstellar photon sailing. This paper begins by presenting known properties of this extremely low density, light absorptive, material. After a review of analytical tools, a number of possible interstellar missions are then considered. The first confirms that a thin-film Sun-accelerated probe deployed at the 0.4-AU perihelion of an initially parabolic solar orbit could reach Proxima/Alpha Centauri after a voyage duration of about two centuries. The next case examined is a thin-film probe accelerated to about 0.033 c by an in-space laser array. Finally, it is shown that a combined aerographite-graphene hollow-body solar-photon sail may have significant advantages in accelerating a generation ship to an interstellar cruise velocity in excess of 900 km/s. Some of the unknowns regarding this substance that must be addressed before this material can be applied to interstellar sail application, including the closest feasible perihelion distance and aerographite performance in the space environment, are also discussed.

Gender differences in correlation of biochemical parameters with the severity of COVID pneumonia and the need for oxygen/mechanical support
Authors: Janković Jelena , Stjepanovic Mihailo , Maric Nikola , Belic Slobodan
Published: November 2024

Background:COVID-19 pandemic had caused a global medical, economic and social problems. High infection rate, heterogenous presentation, lack of previous data and no standardized treatment had led to a need for further analysis, in order to be prepared for any potential new pandemics. We analyzed any possible correlation between gender, laboratory findings and severity of disease with need for oxygen or mechanical ventilation support.  
Methods: 100 patients with confirmed SARS-CoV-2 virus infection enrolled. Baseline characteristics that included age, sex, smoking history, BMI, oxygen therapy or mechanical ventilation support need were recorded. Type and severity of radiological finding determined by chest CT scan.
Results: Majority of our patients were over 61 years old (58.6%), male (57.6%), and had severe radiological finding (bilateral pneumonia 29.3%, ARDS 35.4%), with only 20.2% had not required any oxygen supplementation. Regarding gender and laboratory findings, men have shown statistically significant higher values of CRP, lymphocytes, LDH and ferritin (96.4 vs 87.1, p=0.014; 1.17 vs 0.84, p=0.048; 674.8 vs 609.1, p=0.031; 1263 vs 578.4, p=0.001, respectfully). Severe radiological finding had shown positive correlation with the need for HFNC and/or (N)IMV (p=0.021 and p=0.032. respectfully), as well as with higher values of WBC, LDH and ferritin (p=0.042, p=0.035 and p=0.017. respectfully).
Conclusions: There is a difference between presentation of the disease, as well as analyzed laboratory markers between sexes. The difference is most likely multifactorial and should require further research in order to discover other risk and prognostic factors.

Los encoders ópticos son sensores de desplazamiento cuya precisión se ve fuertemente influenciada por la presencia de vibraciones, siendo los propios fabricantes los que recomiendan la utilización de ciertos dispositivos acoplados al encoder cuando la amplitud de aceleración a la que se encuentra sometido supera un determinado valor. En este artículo se realiza un estudio comparativo entre encoders ópticos lineales transmisivos y reflexivos, multicampo y de un solo campo, cuando se utilizan elementos metálicos y elastoméricos como protección pasiva ante vibraciones. La metodología utilizada se basa en el análisis del comportamiento del encoder en un rango de frecuencias obteniéndose un diagrama de precisión que permite comparar el comportamiento de los diferentes tipos de encoders en distintas situaciones.

O elemento combustível instrumentado (CI) é em todos os aspectos igual aos elementos combustíveis normais dos reatores de pesquisa TRIGA, exceto pela presença em seu centro de três termopares do tipo K (cromel-alumel). Em 2004 o CI foi colocado na posição de maior fluxo de nêutrons do núcleo do reator TRIGA IPR-R1, permanecendo neste local até junho de 2007. Durante este tempo seus termopares monitoraram a temperatura e a potência do núcleo em todas as operações, possibilitando também a realização de experimentos de transferência de calor no reator. Após cerca de três anos de monitoração, os três termopares falharam em suas leituras devido à ruptura dos termoelementos na conexão com os fios de extensão. Este trabalho descreve a metodologia utilizada na recuperação dos termopares do elemento combustível instrumentado, realizados em outubro de 2008 no CDTN. Obteve-se êxito parcial na recuperação da continuidade dos termoelementos. São sugeridos procedimentos a serem adotados para nova tentativa de recuperação e retorno deste elemento ao núcleo, dando maior segurança operacional ao reator. É realçada a importância da existência de pelo menos dois elementos combustíveis instrumentados no núcleo, conforme especificação atual de instrumentação da General Atomics Electronic Systems Inc. e a exemplo dos outros reatores TRIGA em operação atualmente. A monitoração da temperatura do núcleo nas operações é recomendação da Agência Internacional de Energia Atômica (AIEA), sendo esta variável o principal limite operacional de um reator nuclear. A temperatura do combustível foi adotada no Relatório de Análise de Segurança do reator TRIGA IPR-R1 como limite operacional de segurança, não devendo seu valor ultrapassar 550ºC.

Vibraciones libres de una torre de sección variable con vínculos elásticos en su base y una masa excéntrica con inercia rotacional en el extremo superior
Authors: De Rosa María Anna , Martín Héctor , Maurizi Mario José , Vairo Francesco
Published: November 2024

En los últimos años, muchos autores han estudiado el comportamiento dinámico de las torres utilizadas en ingeniería de viento. En particular, una publicación de reciente data hace conocer el cálculo de las frecuencias naturales de vibración de una torre en alta mar, de sección constante y parcialmente sumergida en el agua, con vínculos elásticos en la base y una masa excéntrica con inercia rotacional en la parte superior. Como un avance de esa idea original, y con el fin de optimizar el proceso de cálculo, el objetivo del presente trabajo consiste en determinar las frecuencias naturales de una torre ubicada sobre la costa, de sección variable con directriz exponencial, tomando en cuenta la variación de los vínculos a rotación y traslación en la base, asícomo el valor de la masa excéntrica con su inercia rotacional en el extremo libre. El empleo de la metodología expuesta, en los ejemplos analizados, corroboran la aplicabilidad del procedimiento exacto para la solución de la ecuación diferencial gobernante. Específicamente, adquiere relevancia la coincidencia de los resultados obtenidos, con aquellos hechos conocer en estudios previos, para el caso de una torre de sección constante.
Desarrollo del proyecto robótico del instituto de informática de la universidad federal do rio grande do sul atendido por una división de ingeniería mecánica

El suceso del área de Mecatrónica depende de una fuerte integración entre las áreas de Mecánica, Electrónica y Informática. El proyecto RoboPET, Robótica Inteligente de la Universidad Federal do Rio Grande do Sul (UFRGS) de Brasil, consiste en la construcción de robots jugadores de fútbol en la liga F-180 de la federación RoboCup. El mismo presenta aportes significativos en cada una de las áreas, trabajando de una forma integrada y sinérgica. En el equipo de investigación, además de profesores de Electrónica e Informática, hay Estudiantes de cuatro cursos de Grado: Maestría en Computación, Ingeniería de Computación, Ingeniería Eléctrica e Ingeniería Mecánica. Esos Estudiantes desenvolvieron en un corto tiempo un proyecto mecánico innovador que cumplen los requisitos de la parte de control. Como características del proyecto se puede destacar que este es modular, facilitando montajes, cambios y encortando el tiempo para restaurar los robots. Se debe resaltar que la mayor innovación mecánica se encuentra en el nuevo conjunto de ruedas, que presenta características como transmisión acoplada, un número menor de tornillos con mejor funcionalidad e inclinación de las ruedas. Materiales más leves o más resistentes fueron empleados donde era necesario, utilizando la experiencia mecatrónica que no se tenía antes del ingreso de los mecánicos en el equipo de investigación. El número de ruedas de 3 pasó para 4 en la locomoción de los robots. Esta modificación permite alcanzar velocidad mayor al costo de un consumo de energía un poco mayor. Fueron también desarrollados estudios estructurales que tornaron posible la utilización de material ecológico en la construcción del carenaje de los robots, al contrario de material en acrílico antes utilizado. El desenvolvimiento de la investigación fueacompañada de simulaciones, cálculos, estudios y dibujos, donde todos los avances apuntados en el proyecto estarán descriptos por este trabajo.

Inserto en la temática de las innovaciones, experiencias e investigación en las tecnologías aplicadas, este trabajo describe la realización del último Proyecto Final de Estudios (PFE) por parte de alumnos de la carrera de Ingeniería en Mecatrónica de la Facultad de Ingeniería de la Universidad Nacional de Cuyo y en el marco del convenio que la misma tiene con la de l'École Nationale d'Ingénieurs de Brest (Francia), mediante el cual, dos alumnos concurren anualmente para cursar los dos últimos años de la mencionada carrera, retornando para desarrollar el PFE y luego la PPS en Argentina, a cuyo término egresan con titularidad reconocida por ambas casas de estudios y sus respectivos países. Los PFE se llevan a cabo desde el 15 de agosto al 15 dediciembre de cada año, debiendo totalizar no menos de 600 horas y bajo la tutoría, orientación y supervisión de los autores de este trabajo. Como conclusión, a lo largo de más de tres años desde su implementación, ha quedado demostrado que los PFE se perciben como una clara y potente estrategia de enseñanza con la finalidad de que se alcancen los objetivos propuestos en relación con los contenidos, organizados y secuenciados por la currícula. Ha demostrado ser una forma concreta de enseñar y aprender que postula el modelo pedagógicodidáctico y dentro de un conjunto de pautas específicas orientadas a asegurar ese modelo en la práctica de enseñanza institucional.
