Bridging the gap: implementation of an online induction course to support students’ transition into first year medicine
Authors: McIntyre Kirsty
Published: September 2020

This article was migrated. The article was marked as recommended. Students transitioning into medical school encounter a series of transitions on their journey towards graduation. In the context of undergraduate medicine, students must develop new skills common to all incoming undergraduates (e.g. academic writing, digital skills), as well as subject-specific knowledge, e.g., regarding professionalism or anatomical dissection governance. Whilst the University of Glasgow School of Medicine provides on-campus induction activities, for example to prepare students to participate in problem-based learning, other induction material has traditionally been delivered in a didactic manner.We developed a five-unit online induction course using existing resources available under creative commons licensing. The course used an interactive approach to deliver teaching and signpost key resources related to digital and academic skills (e.g. referencing, avoiding plagiarism), and professionalism. The course was released to incoming students via the institutional public Moodle site prior to their arrival at Glasgow. Student engagement and perception was assessed using quizzes, an online anonymous survey and focus group.Student engagement with the induction course was high: 95% (301/316) of students accessed the course, and 89% (280/316) of students completed the course by achieving 100% in all five end-of-unit quizzes. Students placed particular value on content relating to professional expectations and highlighted that inclusion of current students' testimonies would improve the course. However, the requirement to engage with sections relating to fundamental digital skills was sometimes a barrier to engagement. Overall, the online induction course benefitted students by helping them understand institutional expectations and creating an opportunity to identify their digital skills needs for them to succeed in their studies. These insights will be of key importance in supporting transition as we prepare for remote induction of our students in September 2020, and should be applicable to others interested in adapting and implementing this induction course in their own settings.
On Sparse Discretization for Graphical Games
Authors: Ortiz Luis
Published: September 2020

Graphical games are one of the earliest examples of the impact that the general field of graphical models have had in other areas, and in this particular case, in classical mathematical models in game theory. Graphical multi-hypermatrix games, a concept formally introduced in this research note, generalize graphical games while allowing the possibility of further space savings in model representation to that of standard graphical games. The main focus of this research note is discretization schemes for computing approximate Nash equilibria, with emphasis on graphical games, but also briefly touching on normal-form and polymatrix games. The main technical contribution is a theorem that establishes sufficient conditions for a discretization of the players’ space of mixed strategies to contain an approximate Nash equilibrium. The result is actually stronger because every exact Nash equilibrium has a nearby approximate Nash equilibrium on the grid induced by the discretization. The sufficient conditions are weaker than those of previous results. In particular, a uniform discretization of size linear in the inverse of the approximation error and in the natural game-representation parameters suffices. The theorem holds for a generalization of graphical games, introduced here. The result has already been useful in the design and analysis of tractable algorithms for graphical games with parametric payoff functions and certain game-graph structures. For standard graphical games, under natural conditions, the discretization is logarithmic in the game-representation size, a substantial improvement over the linear dependency previously required. Combining the improved discretization result with old results on constraint networks in AI simplifies the derivation and analysis of algorithms for computing approximate Nash equilibria in graphical games.

Published: September 2020

In this work, we studied the thermal characteristics of flat heaters made of aluminum with a strip heating element in the form of carbon fiber. In order to provide the necessary insulation of the heating element from the metal base, a layer of porous anodic aluminum oxide with a thickness of 20 μm was formed on the aluminum surface. The ends of the carbon fiber filament were metallized with a layer of copper for subsequent soldering during the assembly of the electric heater. The carbon fiber filament of electric heater had an electrical resistance of 60 Ohms. Studies of the propagation of heat fluxes in the volume of a board made of aluminum with nanoporous aluminum oxide were carried out using thermal imaging measurements. The paper presents the dependence of temperature changes on the surface of the lid of a heating element made of aluminum and on the opposite side — heat transfer side with heating time. The results showed that the heat generated by a linear heating element of carbon fiber, quickly distributed throughout the entire volume of the aluminum plate of the heating element. This indicates a high thermal conductivity of the aluminum base of the heater, the parameters of which allow to achieve the required thermal characteristics of the heater.
Mathematical modeling of perspective structures of metal oxides
Authors: Sechenykh P. A.
Published: September 2020

Information about the structure and properties of materials is especially important when working with micro-and nanoscale objects due to the high complexity of their obtaining. This makes it relevant to use computer modeling to predict the required characteristics of materials. Electronic, magnetic, mechanical, and other properties of crystalline substances are determined by their structure-the periodicity of the lattice and the symmetry of the unit cell. This article discusses metal oxides with the general chemical formulas MeO (metals: Ca, Cd, Mg), MeO2 (metals: Hf, Ce, Zr), Me2O3 (metals: Er, Nd, Sc, Mn, Tl) and Me3O4 (using Fe as an example) and a cubic symmetry type crystal lattice — structural types NaCl (rock salt), Fluorite, Bixbyite, Spinel accordingly. The paper describes the model of ion-atomic radii, which is widely used in the modeling of crystalline metal oxides. The application of the annealing simulation algorithm for calculating the metric parameters of the compounds under consideration is shown. The software implementation of the algorithm presented in this paper allows us to determine the coordinates of the atoms that are included in the elementary cell of the crystal lattice, calculate the lattice constant and the density of the packing of atoms in the crystal cell using the specified chemical formula and the space group symmetry. These structural characteristics can be used as input parameters for determining electronic, magnetic, and other properties. The article compares the values of lattice constants obtained as a result of modeling with experimental data.
Issues of implementing neural network algorithms on memristor crossbars
Authors: Morozov A. Yu. , Reviznikov D. L. , Abgaryan K. K.
Published: September 2020

The property of natural parallelization of matrix-vector operations inherent in memristor crossbars creates opportunities for their effective use in neural network computing. Analog calculations are orders of magnitude faster in comparison to calculations on the central processor and on graphics accelerators. Besides, mathematical operations energy costs are significantly lower. The essential feature of analog computing is its low accuracy. In this regard, studying the dependence of neural network quality on the accuracy of setting its weights is relevant. The paper considers two convolutional neural networks trained on the MNIST (handwritten digits) and CIFAR_10 (airplanes, boats, cars, etc.) data sets. The first convolutional neural network consists of two convolutional layers, one subsample layer and two fully connected layers. The second one consists of four convolutional layers, two subsample layers and two fully connected layers. Calculations in convolutional and fully connected layers are performed through matrix-vector operations that are implemented on memristor crossbars. Sub-sampling layers imply the operation of finding the maximum value from several values. This operation can be implemented at the analog level. The process of training a neural network runs separately from data analysis. As a rule, gradient optimization methods are used at the training stage. It is advisable to perform calculations using these methods on CPU. When setting the weights, 3—4 precision bits are required to obtain an acceptable recognition quality in the case the network is trained on MNIST. 6-10 precision bits are required if the network is trained on CIFAR_10.

Authors: Balan N. N. , Ivanov V. V. , Kuzovkov A. V. , Sokolova E. V. , Shamin E. S.
Published: September 2020

The article gives an overview of the main currently used models for the formation of photoresist masks and the problems in which they are applied. The main stages of «full physical» modeling of mask formation are briefly considered in the case of both traditional DNQ photoresists and CA photoresists. The concept of compact models (VT5 and CM1), which predict the contour of the resist mask for a full-sized device topology is considered. Examples of some calculations using both full physical modeling and compact models are given. Using a full physical modeling of the resist mask formation the lithographic stack was optimized for a promising technological process. The optimum thickness ratios for the binary BARC used in the water immersion lithographic process are found. The problem of determining the optimal number of calibration structures that maximally cover the space of aerial image parameters was solved. To solve this problem, cluster analysis was used. Clustering was carried out using the k-means method. The optimal sample size was from 300 to 350 structures, the mean square error in this case is 1.4 nm, which slightly exceeds the noise of the process for 100 nm structures. Using SEM images for calibrating the VT5 model allows reducing the standard error of 40 structures to 1.18 nm.

Lingual Aspects of Mystical Narration in V. Shevchuk’s Novel “The Beginning of Horror”
Authors:   Ivan Franko Lviv National University, Batsevych Florij
Published: September 2020

In recent decades, the researchers of artistic stories have paid their attention to the narrative analysis of a set of weird texts of mystical and absurd content, works of “black humour”, fantastic (khymerna) prose created by a non-anthropic narrator or by an author in a changed state of consciousness. These texts serve the field of actualizing atypical and non-usual narrative structures, the sphere of meaningful changes within the bounds of narrative categories and, which is important, of forming special communicative senses of aesthetic nature. The basic problems of the linguistic analysis of “unnatural” stories are identifying the types of changes in the narration constituents, reasons of these changes and narrative categories (first of all, events, participants, objects, chronotope characteristics, points of view, moduses, modalities, etc.). The article analyses one of the texts of mystical content aiming at the revealing of some specificities of the structure and functioning of the so-called “unnatural artistic narrations”. The object of the research is V. Shevchuk’s novel “The Beginning of Horror”. The subject of the analysis is lingual means of the narrative structure formation, the author’s objectification of the mystical artistic sense and lingual “signals” of a reader’s perception of these senses. The most important semantic means of creating mystical atmosphere of the story are predicates that ascribe the names of their referents atypical dynamic and static features connected with the Christian view of the infernal world. It helps to form narrative events that root in weird situations, which cannot take place in reality. Non-dispositional nature of these situations correlates with the reference to the mystery that goes far beyond the bounds of a usual perceptive and psycho-mental background. Among the pragmatic means of creating mystical atmosphere of the main hero’s story as well as of the novel in general, we specify the individual inimitative perception of the flow of time and modality of “real unreality” formed by the role of an unreliable narrator and a vague point of view of the described event with its perceptive, ideological and time planes of objectification. Due to the increasing interest to various expressions of the esoteric, the increase of the number of artistic works of such content and growth of their popularity, we consider it topical to proceed in further investigations of lingual-narrative aspects of “unnatural” stories, in particular, the ones with the modus of mystical in them.
Stylistic Devices in Yevhen Sverstiuk’s Essay “Cathedral in Scaffoldingˮ
Authors:   Lesya Ukrainka Eastern European National University, Lokaichuk Svitlana
Published: September 2020

The article considers stylistic devices in the essay of Ye. Sverstyuk “Cathedral in Scaffolding” as important linguistic means of expressiveness and logic organization of the publicistic text. Studying the category of expressiveness, which is provided by language means, is especially relevant for the study of the journalistic style genres, which perform two main interrelated functions – informing and affecting the reader. The purpose of the research is to analyze stylistic devices in Yevhen Sverstiuk’s essay “Cathedral in Scaffoldingˮ as important linguistic means of the logical and emotionally-expressive organization of the text. The emphasis is laid on the analysis of the figures of speech, most inherent in the intellectual and polemic style of the author’s narrative, namely, antithesis, parcelling, rhetorical questions, inversion, and stylistic devices of repetition (anaphora, epiphora), composite links. Stylistic devices make the text logical and expressive. The logical function of a stylistic device provides information correctness of the text, promotes its division into semantic segments/ fragments. The expressiveness is achieved by mental operations of convergence or opposition of concepts due to skillful changes of the author’s language tactics and results in the enhanced influence on the reader. Ye. Sverstyuk uses stylistic figures to draw the attention of the addressee (by highlighting keywords), to emphasize his point of view and provide the coherence of the discourse.
Sentence Typology: Communicative Purpose Approach. Tradition and Novelties
Authors:   Taras Shevchenko national University of Kyiv, Shevel Sviatoslav
Published: September 2020

The paper offers the analytical review of the author’s typologies of sentences based upon the purpose of their expression and presented in the East Slavic grammars from the early XIX century to the present day. The main focus falls on the systematization of the parameters of the author’s classifications, which enabled distinguishing among the main approaches to the typology of sentences based upon the communicative purposes: the content – based approach with the analysis of the sentence expression; a formal-semantic one, which is based upon the formal means of representation of the speaker’s purpose, in particular the order of words in the sentence, the form of the members of the sentence, as well as the methodological semantics of verb forms; an approach that presupposes the analysis of the intentions and ties of speakers and subjective components of speech; intonation-punctuation approach; in particular a modal approach based on the concept of “syntactic modality”; modal-intentional approach, which is dominated by the communicative intention of the speaker and discursive-pragmatic approach to the interpretation of communicative types of sentences, which takes into account the most hefty aspects of the speech acts theory. Such a classification, as well as a detailed review of the author’s typologies proved correct to divide the sentences according to expression purpose into three main types: sentence-information (informative); motivating sentences (directives); sentence-question (quisitive). Sentences of desire (optatives) are more appropriately included in the inter-category modifications of sentences-information and prompting sentences. We also proved that among all it is important to single out the content of the sentence-statement, syntactic models of representation of this content, communicative intentions and purpose of the speaker as well as the cognitive environment of sentences-statements.
Modern Era of the Theory and Practice of Learning Activity: Key Issues and Perspectives
Authors: Elkonin B.D.
Published: September 2020

The paper describes the main stages and transitions in the unfolding of the Learning Activity which is reviewed within the framework of D.B. Elkonin and V.V. Davydov’s concepts about the meaning and content of education. The unfolding of teaching/learning is explained through the emergence of a joint action of teacher and students, that is, the Mediative Action. The concept of the Learning Task as a basis for constructing the general method of action, central to the system of D.B. Elkonin and V.V. Davydov, is also considered as a source of learning motivation. The learning task is seen as the distinct opposition between the search for the method of acting (possible scaffolds of acting) and the very achievement of the result, i.e. the opposition between the consideration (of situation) and the immediate achievement (of result), and, therefore, the opposition between the intriguing (interesting) and the required. The paper also focuses on the evolution of modeling as the evolution of sign mediation in the student’s activity. As the student progresses from understanding and configuring the model to using it as a means of acting, the model evolves. Having gained the function of the means, the model becomes a resource of possible action, and that is how the experience of acting appears before the student him/herself. The unfolding of the learning task and modeling is conceptualized as the correlation between functional genesis and ontogenesis.
On the Significance of Questioning in Learning Activity
Authors: Chudinova E.V.
Published: September 2020

The article analyzes and compares modern educational technologies: the so-called ‘leading dialogue’ and the technology for generating student questions in collective learning activity. We discuss the role of spontaneous and provoked meaningful questions in collective learning activity. Using the experimental school course ‘New Biology’ (for 6th—9th grades) as an example, we provide a description of a teacher’s work aimed at promoting questioning in students: the questions are considered as a starting and finishing point in the collective search activity. Also, the article discusses the data of a comparative analysis of questions by students from different grades presented with the same problem. It considers the role of modeling in the emergence of meaningful questions and outlines the conditions in which meaningful questions appear, as well we the effects of systematic questioning in classrooms.

Use, Perceptions, and Awareness of LibGuides among Undergraduate and Graduate Health Professions Students
Authors: Carey John , Pathak Ajatshatru , Johnson Sarah C.
Published: September 2020

Abstract
Objective – This study investigated usage, perceptions, and awareness of library research guides created using Springshare’s LibGuides among undergraduate and graduate health professions students.
Methods – The researchers recruited 100 health professions students in April 2017 from Hunter College, a senior college within the City University of New York system. Participants were asked to complete a paper survey to ascertain their use, perceptions, and awareness of Springhare’s LibGuides.
Results – Nearly two-thirds of study participants were not aware of library-created LibGuides and 68% had never used this tool. Compared to undergraduates, graduate students were more likely to be aware of LibGuides. The use of LibGuides was higher among graduate respondents (43%) than their undergraduate counterparts (30%). The study found low awareness and use of LibGuides among health professions students overall, regardless of age, gender, academic level, and health sciences concentration. Physical therapy students were more likely to use and be familiar with LibGuides than nursing, medical laboratory sciences, and speech-language pathology and audiology students. Participants reported using general subject guides more than course-specific guides, and the most commonly used page was the Databases guide. Of those participants who had used LibGuides, the vast majority (97%) said they found them useful in their studies.
Conclusion – This study demonstrates low usage and awareness of LibGuides among health professions students at a large urban public college. Findings suggest a need for academic libraries serving such students to develop and implement strategies to promote awareness and increase usage of online research guides. The researchers recommend instructing with LibGuides during information literacy sessions and demonstrating their usefulness during reference consultations. Additional strategies include linking LibGuides to course sites through learning management systems such as Blackboard and collaborating with faculty members to better inform students about the guides.
Gathering Evidence of Learning in Library Curriculum Center Spaces with Web GIS
Authors: Stoddart Rick , Godfrey Bruce
Published: September 2020

Abstract
Objective –This article reports on a pilot research project that gathered usage statistics in specifically designated library learning spaces using a Web-based Geographic Information System (GIS). These learning spaces were then mapped to expected learning activities that would occur in these areas based on its intention or design. In this way, the library could begin to associate the usage of a space with different types of learning. The researchers then mapped these learning activities to campus learning outcomes to create learning impact statements.
Methods – The researchers used observation data gathered with a Web GIS tool to examine space usage within the library’s curriculum center.
Results – The pilot study found that student usage of the curriculum center was mainly associated with two campus learning outcomes: (1) Communicate and (2) Learning and Integrate. The evidence also indicated possible design improvements that may make the curriculum centers spaces more functional for students.
Conclusions – The Web GIS tool proved to be a useful tool to gather evidence of student space usage within the library environment. The mapping of individual spaces to learning activities further enhanced the usefulness in interpreting how students are using library spaces. Leveraging the space usage data within learning outcomes statements created another means for the library to communicate its learning impact with campus stakeholders.
Improving Learner-Driven Teaching Practices through Reflective Assessment
Authors: Regan Matthew T. , Young Scott W. H. , Mannheimer Sara
Published: September 2020

Abstract
Objective – Reflective assessment is an effective method of teacher evaluation, serving as an approach for assessing teaching practices, generating insights, and connecting with colleagues, ultimately supporting meaningful transformation of teaching practice. In this paper, three librarians model a reflective assessment approach in evaluating and improving their experiences implementing learner-driven teaching practices in credit-bearing courses in topics related to library and information studies.
Methods – Following a model of reflective assessment, we asked ourselves how our practice can better support learner-driven teaching practices, thus assessing and improving our own teaching and improving students’ learning experiences. Our process involved five steps: cohere around shared viewpoints, identify teaching practices for reflection, conduct reflection, discuss and analyze reflections to produce insights, and apply insights to improve teaching.
Results – We reflect on five different learner-driven teaching practices: co-creative syllabus design, learner-defined personal learning goals, soliciting and responding to learner feedback, interdisciplinary discussions and exercises, and self-evaluation. We discuss improvements and refinements that we implemented in response to our reflective assessment, including more frequent checking in with students; more clarity regarding self-evaluation and grading; one-on-one meetings with all students; allowing students to negotiate, discuss, and determine assignment deadlines and dates; more flexibility with students’ work products; and increased pedagogical transparency. As a further result, our reflective process models an approachable framework for engaging in reflective assessment.
Conclusion – This paper presents a model for reflective assessment of teaching in an academic library. We present a discussion of learner-driven teaching practices, and we offer a practical pathway for other teachers and practitioners to assess their teaching. We find that reflective assessment is an effective and insightful approach for understanding and improving learner-driven teaching practices.

Information and Metrology-Driven Optimisation of Wavefront Error in Telescope-Detected Radiation
Authors: Sychev V.V. , Klem A.I.
Published: September 2020

The paper presents a solution to an information and metrology problem concerning minimising the wave-front error of telescope-detected radiation. As an example, we used aberration computation and simulation describing the optical system of the space telescope installed in the Millimetron observatory. We show that many factors that affect a space telescope decrease the quality of the image obtained. It is necessary to eliminate the effects of the distortion-generating factors and reduce their contribution to the total wavefront error. As the dimensions of the collecting aperture in telescopes increase, the factors that distort the wavefront of the radiation detected by the telescope begin to significantly affect the quality of the image obtained. We consider the ways of decreasing the effects of the distortion-generating factors caused by aberrations in the optical system. One of the solutions to this problem is to select a rational configuration of the space telescope optical system. In order to minimise the aberration, we used the Zemax 13 Release 2 SP4 Premium software package to simulate the optical system, to analyse and optimise it so as to diminish the scattering spot in the exit pupil. We achieved this goal by decreasing the spherical aberration and ensuring a more uniform distribution of it over the field. We used the data obtained to estimate the admissible dimensions of the misalignment spot
Simulation and Prototyping of an Orbital Lightning Detector
Authors: Kvitka V.E.
Published: September 2020

The problem of detecting lightning flashes from space is becoming more and more important as the remote sensing of Earth, climatology and atmospheric physics develop. Orbital lightning detectors are designed both in Russia and abroad. The paper considers the problem of mathematical and physical simulation of a high-speed camera designed to observe lightning flashes from onboard spacecraft in low Earth orbit. Our previous works substantiated the exterior design of the lightning detector, computed its properties and described the algorithms behind the software. In order to validate the design results, we need to prototype the instrument. We describe the main problems of detecting lightning flashes as observed from space. We show a computer simulation method producing snapshots that takes into account the interference generated by the background and the photodetector. We studied the problems of recreating the target environment during prototyping of the lightning detector, accounting for the properties of the phenomenon observed, that is, the flash spot dimensions and the ratio of the background brightness to that of the lightning. We describe the principle of comparing these two types of snapshots (taken by the prototype and synthesised by the software) and compared the results of processing the images obtained. The results matched, which allowed us to validate the snapshot processing algorithm and confirmed that the lightning detector simulation method developed is correct
Finite-Element Simulation of the Eigen Frequency Spectrum of the Cylindrical Resonator with Geometrical Imperfectness
Authors: Basarab M.A. , Lunin B.S. , Chumankin E.A. , Yurin A.V.
Published: September 2020

The solid-state wave gyroscope belongs to the class of the so-called Coriolis vibratory gyroscopes. They are industrially produced, as a rule, in two versions: precise solid-state wave gyroscopes with expensive fused quartz resonators, and devices of low accuracy with metal resonators. The use of metal for the manufacture of a solid-state wave gyroscope resonator for inertial systems of medium and low accuracy can significantly simplify the design of the device and reduce its cost, however, the low-quality factor of the metal resonator and the instability of its dissipative characteristics limit the accuracy characteristics of the solid-state wave gyroscope. The use of high-quality precision fused quartz glass resonators in such solid-state wave gyroscopes is unacceptable because of their high cost. The purpose of the work is to study the characteristics of inexpensive quartz resonators made from industrially produced fused quartz tubes, with the aim of creating a medium-accuracy solid-state wave gyroscope. Using the finite element method, the main types of geometric heterogeneities arising from the production of such resonators and their influence on their spectral characteristics are investigated. The experimental results allow us to draw conclusions about the most significant defects affecting the performance and accuracy of the solid-state wave gyroscopes
Automatic Synthesis of a Continuous Dynamic Stabilization System based on Artificial Neural Networks
Authors: Dotsenko A.V.
Published: September 2020

The article considers an automated process of synthesising a continuous dynamic stabilization system based on multilayer neural networks. We propose a two-stage solution to the synthesis problem. The first stage involved generating the training dataset. It meant solving the optimum control problem for the dynamic system under consideration multiple times with various initial conditions. We derived optimum control for every initial condition as a function of object states. The second stage involved approximation of the training dataset we generated, which used a multilayer perceptron neural network. This perceptron represents a control unit that covers the entire initial condition space of the control object. The innovative aspect of our work is as follows: we reduced the synthesis problem to the approximation problem, that is, we sought a closed stabilising system by means of approximating the optimum controls obtained while minimising a functional of the integral type. The paper presents a numerical experiment in synthesising a stabilisation system for a track-laying robot. In order to test the stabilisation system synthesised, we consider initial conditions outside the training dataset and show how the system operates when externally perturbed

Se hace un análisis del planteamiento de Gardner en su libro "Creating Minds", respecto a las numerosas áreas de producción creativa, para posteriormente analizar al detalle las experiencias y logros creativos de Sigmund Freud a lo largo de su vida, como ejemplo de un individuo creativo-productivo con elevada inteligencia intrapersonal. Finalmente se hace un análisis de las características comunes encontradas entre los individuos excepcionalmente creativos y los factores determinantes en sus logros.
Aportes de género a la salud sexual y reproductiva
Authors: Ragúz María
Published: September 2020

Este artículo trata sobre una investigación de significados relativos al Género -¿qué es el Hombre, la Masculinidad, la Mujer, la Femeneidad?- en parte de una muestra accidental de niños, jóvenes, adultos y ancianos de diversos grupos sociales de nivel socioeconómico bajo en Lima, Perú. Mediante análisis de contenido de entrevistas en profundidad se analizan las respuestas, arribándose, entre otras conclusiones, a que en este grupo no se diferencia sexo biológico de género. Se interpretan los resultados en términos de las implicancias que estas conceptualizaciones del género tienen para las campañas de salud sexual y reproductiva como la educación en sexualidad, la planificación familiar, los talleres de "empowerment"  ("enpoderamiento") y asertividad para mujeres y de conciencia de masculinidad para varones, o las intervenciones en violencia doméstica y abuso sexual. Se destaca la necesidad de trascender los roles sexuales o genéricos, que sustentan relaciones de inequidad y poder en la sociedad peruana.

Critical Limb Ischemia (CLI) is a clinical syndrome in the form of ischemic pain, especially at rest or a tissue loss condition, such as an ulcer or gangrene that does not heal, associated with Peripheral Arterial Disease (PAD). Diabetes mellitus (DM) accelerates atherosclerosis and becomes one of the risks of PAD. It is also known to accelerate the worsening of PAD with a 4x greater risk of developing CLI compared to patients without DM. At the other side, 60-95% of patients who are operated on as a result of limb ischemia are diagnosed with atrial fibrillation (AF). This paper is a case report regarding a patient with CLI as a complication of DM and AF.

Published: September 2020

Introdução: As comunidades rurais são mais sujeitas a processos de empobrecimento, sendo visível que a vulnerabilidade social causa maior preocupação no meio rural do que no urbano. Neste contexto, os Povos e Comunidades Tradicionais apresentam necessidades de desenvolvimento de políticas públicas que envolvam os seus territórios. Objetivo: analisar a legislação que institui as políticas públicas, em âmbito nacional, direcionada para povos e comunidades tradicionais, em especial as comunidades quilombolas. Metodologia: Trata-se de uma pesquisa documental, que buscou na web, as normas legais que tratam da questão ambiental no Brasil. Resultados: Foram encontrados 35 atos normativos, entre os anos de 1964 e 2019, sendo selecionados apenas os vigentes, compondo a lista de documentos: uma constituição, quinze decretos, três instruções normativas, quatorze leis federais e duas resoluções. Estas legislações foram discutidas no contexto dos Povos e Comunidades Tradicionais. Conclusão: Por fim, nota-se que as legislações ambientais que instituem as políticas públicas contemplam estes povos, por serem grupos que apresentam em seus traços culturais a conservação da biodiversidade, o uso sustentável dos recursos naturais e o equilíbrio ecológico. Entretanto não significa que estas regulamentações estejam implementadas e contribuindo para a proteção destas comunidades.
