Authors: Şahin Ayşe , Dalgıç Nazan , Barış Ayşe , Özata Abanoz Banu
Published: February 2021

Objective: For the treatment of invasive candidiasis (IC) which is confirmed or suspected in adults, echinocandins are usually recommended. In children; however, very little is known about using echinocandins for IC management. Micafungin (MCFG) is approved for both treatment and prevention (prophylaxis) of invasive Candida infections. In this study, pediatric patients diagnosed with Candida infection and treated with MCFG were evaluated retrospectively. Clinical characteristics of the patients and the results of MCFG treatment were discussed in light of the literature. Material and Methods: The study included 10 pediatric patients aged between 28 days and 16 years. They were diagnosed with Candida infection between January 01, 2017 and January 01, 2019, and were treated with MCFG. The patients’ microbiological and laboratory data, demographic and clinical characteristics, risk factors for IC, MCFG treatment characteristics and the side effects were recorded retrospectively from electronic records. Results: The median age of the patients in the study was 22 months (range 1.5 to 178 mo). Candida species isolated from the patients were C. parapsilosis, C. orthopsilosis, C. tropicalis, C. albicans, C. kefyr and C. guilliermondii. The most common underlying disease was gastrointestinal anomaly and related problems. The most common risk factors included the use of broad-spectrum antibiotics, total parenteral nutrition, mechanical ventilation, and central venous catheter. The median dose of MCFG was 2 mg/kg per day (d) and was applied to the patients for a minimum of 3 days and a maximum of 23 days. There were no side effects observed. Conclusion: In our limited case series of pediatric patients, MCFG was found effective in treating both proven and suspected invasive Candida infections and no adverse side effects were observed.

Objective: Abdominal tuberculosis is a kind of extrapulmonary tuberculosis that can usually occur during the lymphohematogenous spread of first Mycobacterium tuberculosis infection, develop by neighborhood from an abdominal focus or a mesenteric lymph node. The aim of this study is to evaluate pediatric cases diagnosed with abdominal tuberculosis. Material and Methods: Between 2012-2018, seven patients diagnosed with abdominal tuberculosis through patients who diagnosed with extrapulmonary tuberculosis in our hospital, were included in study. Demographic and clinical characteristics, diagnostic methods, commenced treatments and clinical follow up of patients were listed from medical records. Results: Of patients, four were female. The mean age was 144.2 ± 42.7 months. None of the patients had a history of tuberculosis contact. The median complaint time was 20 days (5-180). The most frequent complaint was abdominal pain and the most frequent physical examination finding was abdominal tenderness. Mean white blood cell count was 9.26 x 103 ± 4.77 x 103 μ/L, C reactive protein level: 79.9 ± 54.9 mg/dL, erytrocyte sedimentation rate: 45 ± 30 mm/h. Tuberculin skin test was positive in two patients, interferon gamma releasing assay was positive in three patients, and in two patients, both tests were positive. There were findings suggesting tuberculosis on pulmonary imaging in five patients and abdominal imaging in all patients. Histopathological examination of the specimens of six patients revealed findings consistent with tuberculosis. The presence of M. tuberculosis was confirmed microbiologically in clinical specimens taken from three patients. The most common abdominal tuberculosis type was mesenteric lymphadenitis. The mean time from admission to diagnosis was 15 ± 12.8 days. All patients recieved antituberculosis treatment. Conclusion: Abdominal tuberculosis should be kept in mind, in patients presenting with abdominal complaints lasting more than five days. Ultrasonography and computed tomography are useful to determine abdominal tuberculosis type. The disease can be sucsessfully treated with standart antituberculosis treatment.

In search of Comenius’ pansophism in the research endevours of Polish scholars
Authors: Sztobryn Sławomir
Published: February 2021

The article deals with the problems of Comenius’ pansophism in his interpretation and in the research of selected contemporary Polish scholars. One of the significant differ-ences between the author of the above dissertation and other contemporary researchers is the treatment of pansophism as a primary concept in relation to didactic solutions. The argu-ments cited in the dissertation justify the importance of pansophism as the basis of Comenius’ work. The characteristics of pansophism present in synthesis the richness of its meanings that are not commonly perceived in the source literature. Authors who pondered over this issue have noticed its historical evolution. However, pansophism is not a historical artifact, but carries numerous consequences that, at least in part, are close to contemporary trends in scientific research.
Pansofia Comeniusa a możliwość poznania wszystkiego
Authors: Kalita Cezary
Published: February 2021

Ideę pansofii jako całościowego i holistycznego ujęcia wszelkiej wiedzy zapro-ponował w naukach medycznych Paracelsus, a w dydaktyce Jan Amos Komeński (Comenius). Opanowanie wszechwiedzy (pansofia) jest dla Comeniusa postulatem moralnym. Jego realizacja jest możliwa poprzez ograniczenie poznania do aktualnej i sprawdzonej wiedzy, która ma charakter podręcznikowy. Aktualizacją wiedzy zajmuje się nauka, a filozofia ma wskazywać nowe pytania i wątpliwości (aporie), które domagają się jednoznacznego rozstrzygnięcia. Celem pansofii jest zarówno zdobycie całej wiedzy, jak i jej utrzymanie, czyli wyeliminowanie ograniczeń poznawczych człowieka (SI, Big data).
Заметка o пансофии Яна Амоса Коменского
Authors: Mnich Roman
Published: February 2021

Текст посвящён сопоставлению двух концепций в научной мысли Яна Амоса Коменского, символически выраженных в понятиях “Pansophism” and “Unum necessa-rium” (“the one necessary” / ”one is needed”). В первом случае речь идёт о всеобъемлющем знании мира и человека, а во втором – о знании только одного/единого необходимого предмета – веры, которую проповедует Иисус (Евангелие от Луки – 10, 42). Эти концепции можно соответственно соотносить с идеологией Ренессанса (Pansophism as “all-knowing”) и барокко (“the one necessary” / ”one is needed”, то есть знание только одного – Бога/Иисуса); они отразились и в русской литературе: например, в произведении Никола Страхова Мир как целое (1872) и в трактате Льва Толстого 1905 года, который называется так же, как и произведение Яна Амоса Коменского –The one necessary.
Polskojęzyczne przekłady dzieł pansoficznych Jana Amosa Komeńskiego
Authors: Hampl Lubomír
Published: February 2021

Przetłumaczenie z języka łacińskiego i czeskiego na język polski fragmentów dwóch istotnych dzieł (Europae Lumina i Conatuum pansophicorum dilucidatio), wprowadza nas w znacznym stopniu w przedmiotową problematykę „naprawy rzeczy ludzkich”. Tłumaczenie tych dzieł wypełnia sporą lukę w polskiej komeniologii. W tłumaczonych na język polski fragmentach widać, jak Jan Amos Komeński wytrwale i z niebywałą uporczywością, zdecydowanie dążył do zaszczytnego celu, jaki sobie wyznaczył – pansoficznej naprawy wszystkich rzeczy ludzkich. Polskojęzyczny czytelnik będzie mógł w końcu zapoznać się (chociażby fragmentarycznie) z tymi dwoma pansoficznymi dziełami w swoim języku ojczystym, w których obecne są również istotne elementy związane z tematyką pedagogiczno-filozoficzną skupioną wokół domeny o charakterze badań interdyscyplinarnych.

Published: February 2021

Offert dans un hôpital de soins tertiaires en Ontario, au Canada, le Programme de bien-être au-delà du cancer procure aux survivants du cancer l’information et les ressources nécessaires pour l’autogestion de leurs soins de suivi (ex. acquérir les notions et compétences pertinentes pour s’adapter à une maladie chronique) après un traitement actif contre le cancer (chimiothérapie, radiothérapie, etc.). Une évaluation a été menée sur la séance de deux heures (composante de l’ensemble du Programme de bien-être au-delà du cancer) destinée aux survivants afin de déterminer si le fait d’y participer avait augmenté les connaissances et suscité l’adhésion au principe d’autogestion des soins de suivi. Les survivantes du cancer du sein (n = 107) et les survivants du cancer colorectal (n = 38) qui étaient présents ont répondu avant et après la séance à des questionnaires portant sur les besoins informationnels et l’intention d’assurer son propre suivi de santé. L’augmentation perçue des connaissances et l’intention d’autogérer ses soins de suivi ne dépendait ni de l’âge, ni du sexe, ni du temps écoulé depuis le diagnostic. Après la séance, les survivants ont dit en connaître davantage (F(1,11) = 144,6, p < .001) et vouloir s’investir dans leurs soins (F(1,103) = 57,3, p < .001). L’amélioration des connaissances était prédictive d’une plus grande volonté d’autogestion (R2 = .64; F(4,86) = 38,5, p < .001). Les survivants du cancer colorectal se sont montrés plus motivés à autogérer leurs soins que les survivantes du cancer du sein (β = .14, t = 2,2, p < .05). Ces résultats guideront l’élaboration et la mise en œuvre des futures séances d’information destinées aux survivants.

Les nausées et les vomissements induits par la chimiothérapie (NVIC) nuisent à la qualité de vie tant des adultes que des patients pédiatriques atteints d’un cancer (Dupuis, Milne-Wren, Cassidy et al., 2010; Farrell, Brearley, Pilling et Molassiotic, 2013; Russo, Cinausero, Gerratana et al., 2014; Hinds, Gattuso, Billups et al., 2009; Sommariva, Pongiglione, et Tarricone, 2016). Les vomissements et les haut-le-cœur sont des symptômes qui s’évaluent objectivement, alors que la nausée est subjective et plus difficile à mesurer. En général, l’intensité de la nausée chez les adultes peut être décrite à l’aide d’échelles d’évaluation visuelle analogique ou qualitative. Il existe à cette fin des instruments validés et recommandés par des spécialistes du domaine, comme celui de la Multinational Association of Supportive Care in Cancer (en ligne : www.mascc.org) (Hesketh, Gralla, du Bois et Tonato, 2016).

Published: February 2021

Background: Undiagnosed astigmatism among children may result in multiple unfavourable consequences, such as poor performance on cognitive and language tasks, reduced oral reading fluency, behavioural disorders, and amblyopia development. In contrast, astigmatism is easily correctable in young children, which highlights the need for periodic assessment of its prevalence amongpediatric populations. Purpose: This study aimed to assess the prevalence of astigmatism among the pediatric population in Jeddah, Saudi Arabia, and to assess the rate of newly detected cases (incidental astigmatism) and the associated risk factors. Patients and methods: This cross-sectional study was conducted among visitors of the awareness campaign about amblyopia, which took place in the Red Sea Mall, Jeddah, Saudi Arabia, on January 29–30, 2016. Children aged 2–15 years were enrolled in the study to undergo noncycloplegic eye examination using an autorefractometer for measuring cylindrical refractive error (Cyl). The calculated sample size for the studied age group of the population of Jeddah, Saudi Arabia was 291. Astigmatism was defined as Cyl 1 diopter in either eye. Multivariate binomial regression was used to analyze the predictors of incidental astigmatism. Results: We examined the eyes of 347 children, mean age = 7.788 (standard deviation = 2.69) years, females = 53.3%. The overall prevalence of astigmatism was 41.5%, whereas the prevalence of incidental astigmatism was 40.6% among 342 children without apparent astigmatism. The prevalence of incidental astigmatism was associated with a previous diagnosis of amblyopia, having a sibling known to have amblyopia, and wearing spectacles. However, only wearing spectacles was shown to predict incidental astigmatism in the multivariate analysis. Conclusion: Astigmatism is highly prevalent among children in Western Saudi Arabia, with the majority being undiagnosed before this screening campaign. These findings urge for further nationwide, population-based studies to address the burden of refractive errors among children in Saudi Arabia. Key words: amblyopia, incidental, population, refractive error, risk factors, Saudi

Background: Globally, the number of visually impaired persons still increases; this will increase demand for more eye care services, programmes, and treatment for the visually disabled individuals. Consequently, the first step is to map the size of the problem. Detection of the related factors of visual loss and blindness is vital to build appropriate treatment, rehabilitation, and service programmes. Public awareness regarding these eye related health conditions is the first step for mapping the problem and public concern for early detection and management. Methodology: A descriptive cross-sectional survey was conducted focused on all adults in Aseer region. The study was conducted during the period from May 2020 to September 2020. Data were collected using pre-structured online questionnaire established by the researchers after intensive literature review and expert’s consultation. The questionnaire data included participants’ socio-demographic data, awareness regarding eye diseases was evaluated and its main domains included glaucoma related awareness, cataract awareness, diabetic retinopathy awareness, refractive errors awareness, and eye dryness. Results: A total of 1,014 participants in the southern region of Saudi Arabia completed the survey. Participants’ ages ranged from 18 to 75 years with mean age of 33.8 (12.2%) years old. Exactly 641 (63.2%) participants were males. Exactly 23.1% of participants defined cataract as a change in lens colour and 17.8% reported that it is an age related disorder. Glaucoma was defined as a disease that causes optic nerve damage by 22.2% of the participants while 18.6% defined the disease as a condition causing diminished peri-ocular vision. DR was defined as retinal vascular lesion disorder by 23.6% of the participants and 42.9% classified the disease as one of the DM complications. In total, good awareness regarding cataract was detected among 13.4% of the participants and 10% had good awareness regarding glaucoma. Conclusions & recommendations: In conclusion, the study revealed that overall public awareness regarding common eye diseases was very poor especially among the old aged and females. The main source of information was a family member or friend who had the disease. Key words: Eye diseases, disorders, cataract, glaucoma, diabetic retinopathy, awareness, population

A teoria de redes complexas tem sido usada para modelar o tráfego de sistemas viários urbanos. O tráfego pode ser modelado como um grafo, caracterizado por métricas de redes complexas. Segundo a literatura, se há um problema de congestionamento ou interrupção do tráfego, é feita uma avaliação do grau de vulnerabilidade ou resiliência do sistema na busca de soluções. O artigo propõe uma abordagem para avaliação da vulnerabilidade do tráfego urbano através das métricas das redes complexas geradas a partir de dados abertos obtidas pelo aplicativo de Ridesharing Uber, utilizando falhas direcionadas. Como diferencial, em relação a literatura, esta abordagem utiliza o conceito de assimetria para a avaliação da vulnerabilidade do tráfego urbano.
Análise do Tempo de Duração de Rotas em Redes Veiculares Considerando Fatores Influentes
Authors: De Assis Danilo Renato , Junior Joilson Alves , Wille Emilio Carlos Gomes
Published: February 2021

As Redes Ad Hoc Veiculares (VANETs) fazem parte dos Sistemas Inteligentes de Transporte (ITS) e têm por objetivo prover a comunicação entre veículos. Por serem redes auto-organizáveis e auto gerenciáveis com controle descentralizado, seu desempenho é totalmente dependente do tempo de duração das rotas. Este trabalho propõe a análise do tempo de duração de rotas em redes veiculares considerando três fatores influentes: velocidade, densidade e sentido dos deslocamentos. Experimentos de simulação comprovam que o tempo de duração de rotas aumenta em redes mais densas e quando os veículos trafegam no mesmo sentido. Além disso, o tempo de duração de rotas não sofre modificações significativas em função da velocidade dos veículos quando essas são limitadas pelo ambiente (como no caso do ambiente veicular urbano).

Published: February 2021

Eventos críticos urbanos precisam ser alertados eficientemente, por exemplo, através de uma notificação rápida. As redes veiculares (VANETs) são uma potencial alternativa, para apoiar a notificação das informações dos eventos críticos arbitrários, devido à sua ubiquidade nas cidades. Embora a dinamicidade das VANETs comprometa o processo de disseminação, as conexões entre veículos a partir dos interesses sociais dos usuários oferecem um modo para otimizar a troca de mensagens e a disseminação de dados. Este artigo propõe SOCIABLE, um sistema de disseminação robusta de dados de eventos urbanos críticos que atua numa rede SIoV. Ele baseia-se em comunidade de veículos com interesses comuns e/ou rotinas similares e na influência social dos veículos pela sua posição na rede, para a escolha dos veículos retransmissores. Numa análise comparativa no NS3 com o sistema MINUET, o SOCIABLE gerou menos 36,56% de mensagens transmitidas numa VANET densa e um pico máximo de atraso de 0,028s numa VANET esparsa, entregando dados de eventos críticos em tempo real e de forma robusta sem sobrecarregar a rede.

Dense 3D Indoor Scene Reconstruction from Spherical Images
Authors: Da Silveira Thiago L. T. , Jung Cláudio R.
Published: February 2021

Techniques for 3D reconstruction of scenes based on images are popular and support a number of secondary applications. Traditional approaches require several captures for covering whole environments due to the narrow field of view (FoV) of the pinhole-based/perspective cameras. This paper summarizes the main contributions of the homonym Ph.D. Thesis, which addresses the 3D scene reconstruction problem by considering omnidirectional (spherical or 360◦ ) cameras that present a 360◦ × 180◦ FoV. Although spherical imagery have the benefit of the full-FoV, they are also challenging due to the inherent distortions involved in the capture and representation of such images, which might compromise the use of many wellestablished algorithms for image processing and computer vision. The referred Ph.D. Thesis introduces novel methodologies for estimating dense depth maps from two or more uncalibrated and temporally unordered 360◦ images. It also presents a framework for inferring depth from a single spherical image. We validate our approaches using both synthetic data and computer-generated imagery, showing competitive results concerning other state-ofthe-art methods.
Motion-Based Representations For Activity Recognition
Authors: Caetano Carlos , Dos Santos Jefersson Alex , Schwartz William Robson
Published: February 2021

This work addresses the activity recognition problem. We propose two different representations based on motion information for activity recognition. The first representation is a novel temporal stream for two-stream Convolutional Neural Networks (CNNs) that receives as input images computed from the optical flow magnitude and orientation to learn the motion in a better and richer manner. The method applies simple non-linear transformations on the vertical and horizontal components of the optical flow to generate input images for the temporal stream. The second representation is a novel skeleton image representation to be used as input of CNNs. The approach encodes the temporal dynamics by explicitly computing the magnitude and orientation values of the skeleton joints. Experiments carried out on challenging well-known activity recognition datasets (UCF101, NTU RGB+D 60 and NTU RGB+D 120) demonstrate that the proposed representations achieve results in the state of the art, indicating the suitability of our approaches as video representations.
Going Deep into Remote Sensing Spatial Feature Learning

Published: February 2021

A lot of information may be extracted from the Earth’s surface through aerial images. This information may assist in myriad applications, such as urban planning, crop and forest management, disaster relief, etc. However, the process of distilling this information is strongly based on efficiently encoding the spatial features, a challenging task. Facing this, Deep Learning is able to learn specific data-driven features. This PhD thesis1 introduces deep learning into the remote sensing domain. Specifically, we tackled two main tasks, scene and pixel classification, using Deep Learning to encode spatial features over high-resolution remote sensing images. First, we proposed an architecture and analyze different strategies to exploit Convolutional Networks for image classification. Second, we introduced a network and proposed a new strategy to better exploit multi-context information in order to improve pixelwise classification. Finally, we proposed a new network based on morphological operations towards better learning of some relevant visual features.

Published: February 2021

Image enhancement is a critical process in imagebased systems. In these systems, image quality is a crucial factor to achieve a good performance. Scenes with a dynamic range above the capability of the camera or poor lighting are challenging conditions, which usually result in low contrast images, and, with that, we can have the underexposure and/or overexposure problem. In this work, our aim is to restore illexposed images. For this purpose, we present UCAN, a small and fast learning-based model capable to restore and enhance poorly exposed images. The obtained results are evaluated using image quality indicators which show that the proposed network is able to improve images damaged by real and simulated exposure. Qualitative and quantitative results show that the proposed model outperforms the existing models for this objective.

Medidas morfológicas de peixes, extraídas de seu contorno, são indicadores importantes com aplicações na indústria pesqueira bem como para monitoramento e preservação das espécies. Assim, técnicas automáticas da extração do contorno tem sido exploradas e o desenvolvimento de métodos de segmentação de imagens de peixes são necessárias. Portanto, o objetivo deste trabalho foi desenvolver um método para medir automaticamente o comprimento do peixe, usando a rede Mask R-CNN na tarefa de segmentação de peixes. Comparando as medidas do comprimento do peixe do método proposto com a medida realizada manualmente, foi obtido um erro relativo médio de apenas 2,26%. Assim, um sistema para a automatização desse processo pode ser mais rápido, mais eficaz e mais escalável.

Published: February 2021

The quality of the images obtained from mobile cameras has been an important feature for modern smartphones. The camera Image Signal Processing (ISP) is a significant procedure when generating high-quality images. However, the existing algorithms in the ISP pipeline need to be tuned according to the physical resources of the image capture, limiting the final image quality. This work aims at replacing the camera ISP pipeline with a deep learning model that can better generalize the procedure. A Deep Neural Network based on the UNet architecture was employed to process RAW images into RGB. Pre-processing stages were applied, and some resources for training were added incrementally. The results demonstrated that the test images were obtained efficiently, indicating that the replacement of traditional algorithms by deep models is indeed a promising path.

Reformbedarf des Kunsturhebergesetzes im digitalen Zeitalter
Authors: Bienemann Linda
Published: February 2021

Hat die Digitalisierung, die Recht und Technik gleichermaßen verändert, einen Reformbedarf des Kunsturhebergesetzes ausgelöst? Diese Frage untersucht die vorliegende Arbeit und legt dabei die folgenden drei Thesen zugrunde: Erstens ist das Kunsturhebergesetz trotz Kollision mit der Datenschutzgrundverordnung vollumfänglich aufrechtzuerhalten und als speziellere Vorschrift vorrangig vor der Datenschutzgrundverordnung anzuwenden. Zweitens ist das Kunsturhebergesetz autonom und somit losgelöst von dem in weiten Teilen harmonisierten Urheberrechtsgesetz auszulegen und weiterzuentwickeln. Das Kunsturhebergesetz weist drittens in mehreren Punkten einen digitalen bzw. internetspezifischen Nachbesserungsbedarf auf.

LA TEORÍA HISTÓRICO-CULTURAL DE VYGOTSKI DESDE UNA PERSPECTIVA FENOMENOLÓGICA
Authors: Montesó Ventura Jorge
Published: February 2021

Mucho se ha discutido sobre la idoneidad de situar a Vygotski en el Olimpo de la psicología. Todavía hoy, 80 años después, sus teorías siguen despertando tantos partidarios, defensores de su originalidad, como efusivos detractores que abrazan las insuficiencias metodológicas de sus trabajos. Una de las insuficiencias que, a nuestro juicio, más ha acusado es la falta de una sólida fundamentación teórica que dote de sentido el gran cúmulo de datos y resultados de que dispone. Por ello, el objetivo del presente artículo es mostrar una factible salida que pasaría por el encuentro, reencuentro en ocasiones, con ciertas proposiciones fenomenológicas, para el caso, desde los estudios fenomenológicos de la percepción y su atención al peso de los predicados culturales, donde el lenguaje se erige como elemento principal y, a la vez, punto de unión con Vygotski, lo que ayudará a reforzar los fundamentos de su propuesta.Many times we have discussed about the appropriateness of situating to Vygotski in the Olympus of psychology. Even today, 80 years later, his theories continue creating as many supporters, defenders of his originality, as effusive critics who accuse the methodological shortcomings of his work. In our view, one of the shortcomings that have accused more his work is the lack of a solid theoretical foundation that endows meaning with the available host of data and results. Therefore, the objective of this article is to show a feasible solution that would be to approach, sometimes encounter with certain phenomenological propositions, for that matter, from the phenomenological studies of perception and its attention to the weight of cultural predicates, where the language is the main element and, at the same time, the meeting point with Vygotski which will help strengthen the foundations of its proposal.

MERLEAU-PONTY Y LA PSICOLOGÍA DE LA FORMA
Authors: Barbaras Renaud , Moreno (traductor) Manfredi
Published: February 2021

A partir del análisis de la relación de Merleau-Ponty con la psicología de la forma, se intenta dar una lectura de su fenomenología como una lectura ontológica de la forma. De este modo, Merleau-Ponty no solo puede pensar una alternativa a la fenomenología de Husserl, sino que le permite elaborar su propia idea de Ser y dar una nueva interpretación de la diferencia ontológica de Heidegger. Desde una descripción fenomenológica de la experiencia perceptiva, a partir de las nociones de comportamiento, forma y estructura, se mostrará enseguida el sentido de ser que moviliza una filosofía de la forma que implicará proyectar un pensamiento de una pertenencia radical de la fenomenalidad a la existencia, y además renovar el sentido de una fenomenología genética que considera toda conciencia trascendental en el marco de una facticidad originaria.On the basis of the relationship Merleau- Ponty establishes with Gestalt psychology, I seek to provide an interpretation his phenomenology as an ontological reading of the notion of form. Therefore, I claim that Merleau-Ponty is able, not only to develop an alternative to Husserl’s phenomenology, but also to elaborate his own idea of Being; in addition, he can offer a new understanding of the Heidegger's ontological difference. From a phenomenological description of perceptive experience, and starting with the notions of behavior, form and structure, I will then show the sense of being mobilized by a philosophy of form. This sense of being implies a projection of a thinking of phenomenality's radical belonging to the existence and, also, renewal of a genetic phenomenology that considers the whole of transcendental consciousness within the framework of an originary facticity
IGNACIO ELLACURÍA Y LA FILOSOFÍA DE ORTEGA Y GASSET
Authors: García Madalena Alfonso
Published: February 2021

En la década de los 50 y 60 del siglo XX Ignacio Ellacuría publicó varios artículos en relación con la figura y filosofía de Ortega. Parte de estos estudios permanecieron inéditos hasta su publicación en las obras completas en el año 1996. El presente estudio lo he dividido en tres bloques temáticos: en primer lugar, los artículos escritos por Ellacuría tras la muerte de Ortega, donde glosa su personalidad y filosofía; en segundo lugar, sus reflexiones sobre la polémica que suscitó el libro de Santiago M. Ramírez y; por último, el estudio que realizó sobre el libro Meditación de la técnica, dicho ensayo por profundidad y extensión podemos considerarlo como uno de los pioneros en el estudio de la filosofía de la técnica de Ortega y Gasset.In the decade of the 50 and 60 of the twentieth century, Ignacio Ellacuría published several articles in relation to the figure and philosophy of Ortega. Part of these studies remained unpublished until its publication in the complete works in the year 1.996. I have divided the present study into three thematic blocks: first, the articles written by Ellacuría after Ortega's death, where he glosses his personality and philosophy; secondly, his reflections on the controversy raised by the book by Santiago M. Ramírez and; finally, the study carried out on the book Meditation on the Technique, the above mentioned essay, for depth and extension, we can consider it to be one of the pioneers in the study of the philosophy of the technique of Ortega y Gasset.
LA VOCACIÓN DEL ACTOR: UNA PERSPECTIVA FENOMENOLÓGICA
Authors: Janer David
Published: February 2021

Con este artículo se pretende ensa-yar y mostrar la virtualidad de una fenomenología de la actitud natural —en la línea en que la desarrollan Schütz, Berger, Luckmann, Ortega e incluso el propio Goffman. El tema del análisis corresponde al mundo del “actor”, concretamente, a una perspectiva: la asunción y vivencia de la profesión como una vocación. ¿Es cierto, como suele afirmarse, que esta profesión es vocacional? ¿Y es cierto, por tanto, que el teatro es el lugar privilegiado para llevarla a cabo? Normalmente, estas son las respuestas que suelen darse. Sin embargo, tras nuestro análisis, veremos que la afirmación ni es tan fácil, ni tan cierta.The following article will attempt to explore and delve into the phenomenology of the natural attitude (along the lines of the work developed by Schütz, Berger, Luckmann, Ortega and even Goffman himself). The subject of the analysis corresponds to the world of the “actor”, more specifically to one perspective: the as- sumption and experience of this profession as a vocation. Is it true, as it is often claimed, that this profession is a vocational one? If so, is it true that the theater medium is the ideal place to conduct it? It is usually assumed that the answers to both questions are affirmative. However, after thorough analysis, we shall see that such affirmations aren’t quite as easy or as certain as they might seem.

Published: February 2021

O interesse pela cultura da pupunha começou a crescer após a década de 70, tendo em vista as qualidades agronômicas, industriais e comerciais. O Estado de São Paulo possui destaque como um dos maiores produtores de pupunha do país, sendo a maior concentração no Vale do Ribeira. Objetivou-se com este trabalho avaliar características de desenvolvimento vegetativo das plantas e produtividade de palmito em função do momento de corte das hastes em cultivo com diferentes densidades populacionais, para o segundo ano de corte. O delineamento experimental utilizado foi o de blocos casualizados em esquema fatorial 2x5 e quatro repetições, sendo os tratamentos com cinco classes de altura de corte do estipe (1,60 m, 1,90 m, 2,20 m, 2,50 m e 2,80 m) e duas densidades de plantas (5.000 e 10.000 plantas ha-1). O experimento foi conduzido na fazenda do Campus Experimental de Registro da UNESP. As análises foram realizadas em dois momentos, março e setembro de 2016. Hastes de 2,8 m colhidas no mês de março obtiveram maior diâmetro do caule, número de folhas e quantidade total de palmito produzido. Hastes com a mesma altura de corte, porém colhidas no mês de setembro proporcionaram maior produção de palmito picado, rodela, tolete e quantidade total de palmito pupunha.

The use of herbicides, in particular clomazone and glyphosate, applied in isolation or in a tank mix, is very common in rice, soybeans, corn and sugarcane fields and the drift of these herbicides can cause damage in sensitive species grown nearby. The purpose of this work was to evaluate the effects of the simulated drift of clomazone and glyphosate applied in an isolated way or mixed in a spray on lemon tree plants. The experiment was installed in a greenhouse in pots with a capacity of 15 L containing sieved soil and an experimental design of randomized blocks was adopted, arranged in a 3 x 5 factorial scheme, with four replications. Plants with two years of development were used. The treatments tested were, clomazone, glyphosate and both mixed, and the decreasing doses of the recommended commercial product: 100, 75, 50, 25 and 0% to simulate herbicide drift. Was evaluated variables, phytotoxicity at 14, 28, 46 and 100 days after application of treatments; plant height, crown volume, the trunk diameter of the rootstock, trunk diameter of the graft and trunk diameter at the grafting point at 0 and 100 days after application of treatments; and liquid assimilation of CO2 at 10 and 60 days after application of treatments. Among the tested herbicides, the one that presented the highest phytotoxicity and the lowest liquid assimilation of CO2 in lemon tree plants was the glyphosate + clomazone mixture. Increases in trunk diameter of the rootstock, grafting point, graft and crown volume did not show significant effects with simulated drift. The plant height presented a greater reduction with the increase of the herbicide doses, mainly glyphosate. That there are considerable losses in lemon tree plants when herbicide drift occurs, mainly by glyphosate and its mixture with clomazone.

Caseous lymphadenitis (CL), a contagious infectious disease caused by Corynebacterium pseudotuberculosis, stands out with great economic relevance for goat breeding in the country because it is one of the main causes of carcass condemnation and intense depreciation of the leather of small ruminants. The objective was to carry out a descriptive study of the clinical and epidemiological aspects of CL in goats in the state of Pernambuco and also to evaluate the detection of C. pseudotuberculosis in milk, blood, and stool samples by real-time PCR. Six hundred and forty-three goats were evaluated, of which 76 (11.8%) presented clinical signs suggestive of CL. And 88.9% (24/27) of the breeding was considered focus. Among symptomatic animals, 25 were selected and submitted to the collection of abscess content for bacteriological isolation. Milk, blood, and stool samples were analyzed for PLD gene detection by real-time polymerase chain reaction (PCR). Out of the 25 samples of abscess content, 72% (18/25) were positive. The PLD gene was detected in the frequencies of 8% (2/25) and 4% (1/25) in milk and blood samples, respectively. Caseous lymphadenitis is possibly widespread in the dairy herds of goats in the state of Pernambuco, especially in adult animals, with a higher occurrence of submandibular lymph node abscesses. The preliminary detection of C. pseudotuberculosis by mammary and hematogenous pathways may contribute to future approaches on the mechanisms of organic dissemination performed by the pathogen. However, it has little relevance to diagnosing the disease.
