Authors: Spindler F T , Herterich V , Holzapfel B M , Böcker W , Polzer H , Baumbach S F
Published: October 2022

Purpose

The aim was to conduct a systematic literature review and meta-anaylsis to analyze the diagnostic accuracy of the external rotation stress test (ERST) for syndesmotic injuries.

Methods

The systematic review was conducted according to the PRISMA-P guidelines (Prospero ID: CRD42021282457). Four common databases were searched from inception to September 29, 2021. Eligible were any studies facilitating the ERST under fluoroscopy in a defined state of syndesmotic instability. Syndesmotic ligament-specific rupture must have been proven by MRI, arthroscopy, or controlled dissection (cadaver study). Two reviewers independently conducted each step of the systematic literature review. The risk of bias was assessed by the Quality Appraisal for Cadaveric Studies Score scale. The data analysis was performed qualitatively and quantitatively.

Results

Eight studies were eligible for a qualitative analysis, and six studies were eligible for a quantitative analysis. All studies included were cadaver studies. The qualitative analysis comprised 94 specimens and revealed considerable heterogeneity. Six studies allowed for a quantitative analysis of the tibiofibular clear space (TFCS) and five studies for the medial clear space (MCS) during the ERST. The quantitative analysis of the TFCS revealed no significant differences between intact and any stage of syndesmotic injury. The MCS was able to differentiate between intact and 2-ligament- (Z = 2.04, P = 0.02), 3-ligament- (Z = 3.2, P = 0.001), and 3-ligament + deltoid ruptures (Z = 3.35, P < 0.001).

Conclusion

The ERST is the only noninvasive test to assess syndesmotic instability and can be conducted bilaterally. The uninjured contralateral side can serve as a baseline reference. Based on the conducted quantitative analysis, the MCS seems to be able to differentiate between stable (intact/1-ligament) and unstable (2-ligament/3-ligament) lesions.
Coagulopathy management of multiple injured patients – a comprehensive literature review of the European guideline 2019

Published: October 2022

The European guideline on the management of trauma-induced major bleeding and coagulopathy summarises the most relevant recommendations for trauma coagulopathy management.

The management of trauma-induced major bleeding should interdisciplinary follow algorithms which distinguish between life-threatening and non-life-threatening bleeding.

Point-of-care viscoelastic methods (VEM) assist target-controlled haemostatic treatment. Neither conventional coagulation assays nor VEM should delay treatment in life-threatening trauma-induced bleeding.

Adjustments may be rational due to local circumstances, including the availability of blood products, pharmaceuticals, and employees.

Published: October 2022

Coronavirus infection caused by the SARS-CoV-2 virus is a multifaceted disease due to generalized vascular endothelial damage. Endothelial damage also underlies COVID-associated coagulopathy.

The paper presents a case of coagulopathy causing myocardial infarction in a 43-year-old patient with no history of coronary disease. We have reviewed the available literature for the pathophysiological rationale of the assumed possibility of coronary thrombosis resulting from coagulopathy with the intact intima of the coronary arteries.

Conclusion. The present observation of coronary thrombosis with radiographically intact coronary artery intima confirms the important role of coronavirus infection in triggering endothelial dysfunction. Currently, the most effective strategy for this type of coronary lesions is the use of anticoagulants and antiplatelet agents along with ECG, echocardiography and troponin level monitoring.
Inotropes and Vasopressors Use in Critical Care and Perioperative Medicine: Evidence-Based Approach (Review)

Published: October 2022

Inotropes and vasopressors are frequently required in critically ill patients and in patients undergoing major surgery. Several molecules are currently available, including catecholamines, phosphodiesterase-3 inhibitors, vasopressin and its analogues, and calcium sensitizers.

We will review current evidence on inotropes use in perioperative and critically ill patients, with focus on most recent randomized controlled trials (RCTs).

Despite being widely used in anesthesia and intensive care, evidences on safety and efficacy of inotropes are scarce. Data from observational studies suggest that inotropes administration may increase mortality in cardiac surgery, acute heart failure, and cardiogenic shock patients. However, randomized controlled trials did not confirm these findings in acute care settings.

Epinephrine has been associated with increased mortality especially in cardiogenic shock, but randomized trials failed to show evidence of increased mortality associated with epinephrine use. Norepinephrine has been traditionally considered contraindicated in patients with ventricular dysfunction, but recent trials suggested hemodynamic effects similar to epinephrine in patients with cardiogenic shock. Dopamine has no additional advantages over norepinephrine and increases the risk of tachyarrhythmias and may increase mortality in cardiogenic shock. Phosphodiesterase-3 (PDE-3) inhibitors are equivalent to catecholamines in terms of major outcomes. Levosimendan is the most investigated inotrope of the last 30 years, but despite promising early studies, high-quality multicenter RCTs repeatedly failed to show any superiority over available agents. There is no highquality RCT clearly demonstrating superiority of one agent over another. In summary, current evidence suggest that the choice of inotrope is unlikely to affect outcome, as long as the target hemodynamic goals are achieved.

Finally, in recent years, mechanical circulatory support (MCS) has become increasingly popular. Thanks to improvement in technology, the safety and biocompatibility of devices are constantly growing. MCS devices have theoretical advantages over inotropes, but their use is limited by costs, availability, and invasiveness.

Conclusion. Future studies should investigate safety, efficacy, and cost-effectiveness of primary MCS versus primary inotropes in patients with acute cardiovascular failure.
Piloting wet tensile strength development of polyamide-amine-epichlorohydrin wet strengthened nordic bleached softwood pulp paper by alkyl ketene dimer internal sizing

Published: October 2022

The results of recent laboratory-scale studies regarding the joint effects of wet strengthening agent polyamide-amine-epichlorohydrin (PAE) and internal alkylketene dimer (AKD) sizing on Nordic bleached softwood pulp (NBSK) handsheets indicate that AKD internal sizing increases the wet strength of PAE wet strengthened handsheets. The boosting effect of the internal AKD sizing was long-lasting. At the molecular level the actual mechanism behind the effect is unclear. The present study examines if the enhanced effect of internal AKD sizing, which is potentially exploitable in practice, also occurs in paper made by VTT’s Suora pilot paper machine. The trials were done using a similar type of NBSK pulp and the same chemicals as in the laboratory-scale studies. The paper was formed at 400 m/min using a hybrid dewatering mode (Fourdrinier + gap). Just as in the laboratory-scale studies, the internal AKD sizing of PAE wet-strengthened NBSK paper resulted in a long-lasting increase of the paper wet strength. In accordance with the laboratory trials, internal AKD sizing had no noticeable effect on the dry tensile strength of the pilot-made paper. The only apparent difference to the earlier observations was an increase of dry tensile strength of the paper treated solely with PAE.

Purpose: to investigate the effectiveness of teaching martial arts students to run 1500 m using rhythmic stimuli. Material and methods. The following methods of pedagogical research were used to solve the research tasks: theoretical (analysis, synthesis, comparison, generalization of abstraction) and practical (observation, testing, experiment, mathematical and statistical). Martial arts students aged 18,5±0,5 years of the II year of full-time education took part in the study (n=20). Results: іndicators indicating the economy of a runner's movement were selected as characteristics that determine mastery of running technique: MAV – maximum aerobic speed; VO2max is the maximum rate of oxygen absorption. We believe that in conditions of limited time for running training (8 classes), the very increase in running efficiency indicates the athlete's understanding of the essence of this motor action. As a stimulating factor in the experimental running training program of martial arts students, running with a metronome was used with a given frequency, which increased in each session from 157 beats/min. up to 165 beats/min. The students had to run first, synchronizing their steps with the metronome, and after rest, reproduce the learned rhythm without external stimulation. The martial arts athletes of the control group studied running according to the traditional program for the same amount of time. The result of the study was significantly (p<0,05) higher indicators of running cadence and results of running at the reference distance of 1500 m in the group of martial arts students who practiced using rhythmic stimuli. At the same time, there were no significant differences in the MAV and VO2max indicators in the wrestlers of both groups during the entire study period (p>0,05). This indicates the effectiveness of running training in the experimental program, by improving running efficiency, rather than increasing the level of endurance. Conclusions. It was established that 8 training sessions of long running for 120 min. per week do not contribute to the increase of MAV and VO2max in martial arts students who studied both by traditional and experimental methods. The effectiveness of the application of external rhythmic stimuli with the help of a metronome in teaching martial arts students to athletics running, which is characterized by an increase in running cadence, has been revealed. This indicates an improvement in the level of ownership of transportation equipment while increasing its economy. Keywords: running, training, cadence, MAV, VO2max, pace, rhythm, martial arts, preparedness.

Рurpose: of the study is to track changes in the balance indicators of taekwondo players aged 13-14 under the influence of exercises on unstable support. Material and methods. 8 taekwondo athletes aged 13-14 (4th year of training) participated in the study. To implement the tasks of our research, the following methods were used: to establish the relevance of the topic and select appropriate tests, an analysis of scientific and methodical literature was conducted; to determine balance indicators, Romberg's test was performed on the right and left leg, with eyes open and closed, and a test according to the Yarotskiy method; in order to check the effectiveness of exercises on an unstable support, a pedagogical study was organized and the obtained indicators were analyzed by methods of statistical information processing. Pedagogical testing was conducted remotely through the zoom virtual conference platform for each individual athlete in a separate conference session. Results: indicators of balance development of taekwondo players aged 13-14 have been established at a sufficient level. There was no difference between the performance of balance test exercises on the left and right leg in athletes (at p˃0,05). Performance indicators of the Romberg test while standing on one leg with eyes open are significantly higher than performance of this task with eyes closed (at p˂0,01). After the conducted pedagogical study, the balance indicators of young athletes in almost all test exercises underwent positive changes: the performance indicators of the Romberg test on the right and left leg with open eyes improved by 10,1 % and 7,6 %, respectively (at p˂0,05); with eyes closed improved by 11,6 % when performing the test on the right leg and by 14 % on the left leg (at p˂0,05). The results of the Yarotskiy test in our study had an improvement of 10,8 %, but did not have reliability (at p˃0,05) Conclusions. The suggested exercises of an imitative nature, which are performed on a non-sticky support, have a positive effect on the development of coordination abilities of taekwondo players, in particular, balance. Keywords: taekwondo player, coordination, balance, development, sports training, unstable support.

Purpose: to analyse the results of selection and performance of judokas at the Olympic Games Tokyo 2020 depending on their age indicators. Material and methods. During the study of this direction of research the following methods were used: theoretical analysis and generalization of scientific and methodical literature, analysis of competition protocols of the Olympic Games Tokyo 2020, analysis of the world ranking of elite athletes according to the IJF. Linear regression analysis was used to represent the relative age as one of the indicators of measuring the success of elite judokas. Results: the total number of female judokas - 1444, in all weight categories, who participated in the selection for the Tokyo 2020 Olympic Games and 192 athletes who performed at the Tokyo 2020 Olympic Games were studied based on data from the official website of the International Judo Federation. After analyzing the performances of 192 female athletes at the Tokyo 2020 Olympic Games, it can be seen that the percentage of younger than average age judokas was 59 % (113 athletes), and older than average age judokas – 41 % (79 athletes). After a comparative analysis of the relatively younger average age of female athletes who passed the selection with those who passed it for the Tokyo 2020 Olympic Games, it can be seen that the percentage of younger judokas is only 9 %, while the percentage of older judokas relative to the average age of judokas is 43 %. This may be due to the fact that older relative to the average age female athletes can be much higher in the direction of cognitive development (decision-making, abstract thinking, creativity, acquisition of competitive experience and psychological factors) than younger relative to the average age female athletes, who mostly use this selection to gain competitive experience. Further analysis showed that younger female athletes who took part in the Tokyo 2020 Olympic Games accounted for only 9 % of all judoka who passed the selection. While the number of older judokas relative to the average age is 41 % of all those who have been selected for the Tokyo 2020 Olympic Games. Having a gap in age from 20 to 42 years, high-class female athletes who took part in the Tokyo 2020 Olympic Games have a peak age of 28-31 years. Conclusions. Thus, older judokas should spend less time to win than younger athletes. Gaining with age the experience necessary to participate in high-ranking competitions, it is necessary to take into account that the functional capabilities of athletes decrease with age. Keywords: judo, judo women, age indicators, average age, older, younger, weight category.
Key capabilities for promoting student feedback literacy
Authors: Mamad Abderrahim
Published: October 2022

Feedback literacy in higher education has come as a reaction to the ineffective focus on teacher's delivery of feedback and its passive reception by students rather than on students' active participation in receiving feedback and constructing it (Nicol & Macfarlane-dick, 2006; Nicol, 2019). Therefore, the aim of this theoretical paper is to identify students' capabilities of feedback literacy. To meet this objective, three questions are targeted: 1) How is feedback literacy defined? 2) How is it characterized? 3) What are its practical dimensions from student's perspective? Based on the analysis of theoretical and empirical studies retrieved via reliable databases, a thorough description of the existing definitions of feedback literacy and its frameworks (Carless & Boud, 2018; Carless & Winstone, 2020; Molloy, Boud, & Henderson, 2020; Sutton, 2012) can be highlighted. Four dimensions of student feedback literacy and their adaptation to the writing context are also targeted: appreciating feedback, making evaluative judgments, managing affect, and acting upon feedback (Carless & Boud, 2018). This paper is relevant because it addresses the shift from feedback as a one-way process of transmitting information from instructors to feedback as a process of using diverse communication channels, through which teachers and students collaborate to improve learning outcomes.

The publication shows problems connected with entrepreneurship in their theoretical dimension. It has been worked out on the basis of a wide critical analysis of the academic literature. The aim of this scientific work is an attempt to capture the essence of entrepreneurship and to look at entrepreneurship from the perspective of its functions. Two research questions have been posed, and the answers to them have been looked for. A kind of added value to this particular work is an attempt to show the holistic approach to entrepreneurship which is based on preserving the noumenal and the ontological congruency. This perspective refers to the problems of philosophical anthropology, the foundation of which is personalism. The adoption of a holistic perspective, based on a personalistic foundation, was dictated by the basic assumptions of this current form of modern philosophy, where the centre of interest are issues related to the place and role of a person in the surrounding world, as well as man’s attitude to his products, and works that can be the result of entrepreneurial activities. The research perspective presented in this way enables, according to the author, to ensure the development of three basic categories of values, the importance of which is indisputable in the implementation of entrepreneurship ideas. These are the values: − related to the personal development of an individual – an entrepreneurial person, − reflected in social and economic relations, and also − of a mixed nature. The theoretical divagations have also made it possible to work out the model of a holistic perspective of an approach to entrepreneurship which constitutes the unique, creative way of scientific reflection pointing out to the discovery of the entrepreneurship functions perceived as: personalistic function, personalistic entrepreneur, managerial activities seen as personalistic and phenomenological as well as a market function based on economic personalism.

The article deals with the issue of regional development in the context of the paradigm called the new regionalism. The main aim of the analysis was to show the essence and specifics of the concept of new regionalism in relation to contemporary development processes in the regional dimension. In the first part of the article – using the method of analysis of the literature on the subject – a concise characterisation of the most important trends and directions of changes in the theoretical approaches to regional development was made. On this background, the discourse of the new regionalism was presented, focusing on the discussion issues of ideological, scientific and practical character identified in the studies on regionalism. Then the essence of the new regionalism as a development paradigm for modern regions was presented. In the last part of the article, the main threads of the critical reception of the concept of new regionalism are mentioned. The analysis and characteristics carried out in the article lead to the conclusion that the paradigm of new regionalism is – despite some weaknesses – an adequate response to contemporary development trends and global transformations. It creates a chance to overcome development problems in each region, among others, by using mechanisms and resources of independent, sustainable development and, as a result, reducing inequalities and socio-economic disproportions between regions.

In global conditions, clusters are obliged to operate on the international market to a greater extent than ever. Due to the evolution of the economic environment, these structures, and in particular their entities-members, wanting to increase their competitiveness and develop, take actions on global markets, and engage in international cooperation. Hence, their support towards internationalisation, which determines their functioning and success in the market, is of great importance. That is why the offer of activities supporting this process, both at the EU and national level, is so important. This support should apply in particular to Key National Clusters, which are of exceptional importance for the country and the regions in which they operate. The aim of the article is an attempt to show the essence and function of the cluster structure, which is an example of a business model. In the following parts of the study, attempts were made to introduce the concept and classification of business models and the concept of the international cluster model. The advantages of the internationalisation of cluster structures are presented, as well as the sources of financing and forms of support for this process. Examples of key cluster structures in Poland were presented, as well as the “Aviation Valley” Cluster as a case study. In order to show the role of clusters in increasing efficiency, innovation and competitiveness, the results of our own research were used. They were carried out in 2015 among 80 entrepreneurs-participants of four agri-food clusters, as well as among 4 representatives of institutions managing these clusters in the Podkarpackie Voivodeship. The study puts forward the thesis that properly functioning cluster structures contribute to an increase in the level of innovation in the economy and the competitiveness of entities, eliminating the inequalities in their development, both at the local, regional and international levels.

This publication presents the role of clusters in the innovative capacity of regions based on the example of the Małopolska voivodeship. The background is the analysis of the relevant legislation and reference works. Any statistical data was derived from the resources of the Marshal’s Office of the Małopolska Voivodeship, the Polish Patent Office and the Local Data Bank of Statistics Poland. Based on the reference works, the aspects of cluster structures in the innovative processes of the region were discussed in the article. The first part defines the notion of innovative capacity as an economic category which does not refer solely to the enterprise level but comprises individual regions as well. The above was connected with the cluster structure concept, identifying the benefits and opportunities resulting from entities’ cooperation within clusters which translate into the innovation environment development as well. In the second part of the article, the individual aspects relating to cluster function in the Małopolska voivodeship were discussed, and their selected impact on the innovative capacity of the region was presented. To depict the innovation potential of the Małopolska voivodeship, four statistical indicators concerning the introduced innovations (when compared to the other regions) were linked to data on the cluster cooperation in the region. Referring to the traditional perception of the innovative capacity, the article’s conclusions include relevant findings concerning the cluster structure’s role in the innovative processes of the region.
Teacher readiness to implement learning through play in Ukrainian primary schools: a preliminary study
Authors: Gura Tetiana , Gura Oleksandr , Castanheira Patricia , Roma Oksana
Published: October 2022

The article examines the problem of teachers' professional readiness to implement play-based, activity-based learning methods and the “learning through play” approach in Ukrainian primary schools in the context of holistic reform of school education - the introduction of the New Ukrainian School Concept.
The modern school reform, which was introduced in 2018, brought changes to all aspects of education in Ukraine, however, it was mainly focused on the approach of teaching and learning. A new educational strategy based on the integrative approach of “learning through play”, which combines the principles and methods of active learning, experimental learning and guided discovery learning, inquiry learning, problem-based and project-based learning, and Montessori pedagogy, was introduced in the professional activity of primary school teachers.
The results of the conducted research indicate that the vast majority of interviewed Ukrainian primary school teachers showed an insufficient level of professional readiness for the introduction of play-based and activity-based learning methods due to: a negative attitude to play in education; their insufficient awareness of the developmental, didactic and other functions of the play in the comprehensive development of a person at all stages of his/her life; the dominance of an authoritarian style of communication with students, etc. It was found, that there is an apparent contradiction between the predominantly high level of self-esteem of primary school teachers of their own readiness to implement play-based learning methods and a negative attitude towards the need to change their professional activity.
The difficulties, revealed by the results of the research, provide the basis to make corrections in the system of higher and postgraduate pedagogical education in order to develop Ukrainian school education based on the principles of priority of the individual needs of the child, the competence approach, partnership and a safe educational environment
Revealing the significance of the influence of vanadium on the mechanical properties of cast iron for castings for machine-building purpose
Authors: Frolova Liliia , Barsuk Andriy , Nikolaiev Denys
Published: October 2022

The object of study in this work is cast iron with lamellar graphite, modified with two types of modifiers – FeSi75 and FeSi40V7. In this work, the influence of vanadium on the mechanical properties of cast iron used for castings for engineering purposes was determined.
The existing problem lies in the fact that ignorance of the influence of the alloying element on the mechanical properties of the alloy does not allow determining its consumption rates during the melting process. This can lead to unnecessary costs for materials for melting and casting, and not be justified in terms of the expected improvement in properties.
To determine the effect of vanadium on properties, three indicators of the quality of cast iron are considered: tensile strength, stiffness, and a generalized quality index for mechanical properties. A decision is proposed on the procedure for checking the significance of the influence of vanadium within the considered range of variation V=0.04–0.078 % on these indicators.
It has been established that the introduction of vanadium into cast iron as part of the FeSi40V7 modifier leads to a decrease in the tensile strength by 4 %, but to an increase in rigidity by 2 %. A significant influence of vanadium with a probability of 95 % was also established with respect to the generalized quality indicator for mechanical properties – the introduction of vanadium contributes to a drop in this indicator by about 5 %.
As a result, it was concluded that the use of vanadium in the composition of FeSi40V7 within the final content in cast iron at the level of 0.04–0.078 % can be expedient only if it is necessary to increase the hardness of cast iron due to the promotion of carbide formation during alloy crystallization.
The presented study will be useful for machine-building enterprises that have foundries in their structure, where cast iron is smelted for the manufacture of castings.
Aging analysis of textured water-repellent coatings under ultraviolet radiation and water
Authors: Myronyuk Oleksiy , Baklan Denys
Published: October 2022

The object of research in this work is a coating based on styrene butyl methacrylate binder and calcium carbonate modified with stearic acid. The existing problem is that the stability of the properties of superhydrophobic coatings when interacting with environmental factors – ultraviolet radiation, water vapor or dynamic action of water is limited. Establishing the relationship between the change in the chemical composition and texture of structured water-repellent surfaces under the influence of environmental factors is an essential step towards creating a stability model for such coatings. The work carried out is aimed at establishing the nature of the loss of water repellency of textured organo-mineral coatings under exposure to ultraviolet radiation in the UV-A range and water.
UV resistance testing was performed in accordance with ASTM D 4329. The surface texture was examined using electron microscopy. The study of the change in chemical composition was performed using the IR spectroscopy method.
As a result, it was shown that, under UV radiation, the most vulnerable component of organo-mineral coatings consisting of styrene-butyl methacrylate polymer and calcium carbonate modified with stearic acid is the polymer matrix, the oxidation of which leads to surface hydrophilization. The action of water in both static and dynamic modes leads to the loss of the upper layer of microparticles which forms the structure. It was found that in the surface layer of the polymer, upon irradiation with ultraviolet, the formation of polar carboxyl groups occurs at the initial stages of irradiation, which is accompanied by noticeable hydrophilization. Based on the obtained results, one of the ways to increase the resistance of additive water-repellent coatings to environmental factors can be the use of polymers that are more resistant to UV radiation. An alternative way is to use the optimization of the interfacial contact, which will ensure the slowing down of the loss of texture elements in the water environment.

The object of research is the synthesis of methanol under medium pressure, and the subject of research is the calculation of the equilibrium composition. A method and an algorithm for calculating the equilibrium composition of products are proposed. Calculations have been carried out using two mechanisms of methanol synthesis. First of all, the first approach to the mechanism of methanol synthesis was applied, which provides for the formation of methanol from a mixture of carbon oxides and hydrogen by the simultaneous reaction of methanol synthesis from carbon monoxide (IV) and steam reforming of carbon monoxide (II). The poor convergence of the system of two equations on the basis of this interaction mechanism is established, which complicates the selection of initial approximations and the choice of a real solution. At the second stage, the mechanism of the formation of methanol from carbon monoxide (II) with the simultaneous flow of steam reforming of CO in the opposite direction is considered. The degree of the equation describing the dependence of the equilibrium constant on the partial pressures of the reactants decreases in comparison with the first approach and causes much better convergence when solving the system of two equations. The use of a coefficient that takes into account the effect of pressure on the value of the equilibrium constant is proposed, and its dependence on temperature is approximated. The developed algorithm is implemented in MathCAD, while the relative maximum deviation for methanol is 8.53 %. The third approach is to use two coefficients that adjust the equilibrium constant depending on pressure. In this case, the relative maximum deviation of methanol is 16.25 %. The program according to the proposed algorithm takes into account the multiplicity of the initial data, namely the possibility of varying the composition of the initial mixture, pressure and temperature. The calculation was carried out according to the initial data of industrial implementation of methanol synthesis. Comparison of the equilibrium concentration of methanol with the real one at the outlet of the synthesis column established the degree of equilibrium reaching 39.4 %, which indicates the presence of a reserve of methanol synthesis and the possibility of increasing the practical yield of methanol.

Este artigo trata como tema central do desafio do processo de inclusão educacional, que requer discussão aprofundada e busca de formação, envolvimento familiar, recursos financeiros, e a aplicação de políticas educacionais específicas na escola. Este estudo busca analisar a percepção de docentes de Apoio Educacional Especializado e coordenação a respeito das práticas de inclusão na escola, levando-se em consideração o especialismo, o saber docente, o direito ao uso da sala de recursos no contexto da escola pública municipal de São Bernardo do Campo. O método utilizado pesquisa de campo do tipo qualitativa, usando como instrumento entrevistas semi estruturadas com a coordenação e professores AEE que atuam no ensino fundamental de uma escola pública municipal de São Bernardo do Campo, a sua apreciação é efetuada sob a forma de análise de conteúdo, estabelecendo uma relação entre os dados recolhidos e os contributos teóricos. Nossos resultados indicam que o processo de inclusão escolar ainda é considerado difícil para os professores e coordenadores. Conclui que é necessário expandir o debate crítico sobre diagnóstico e necessidades médicas das crianças, também a sistematização das políticas públicas e o envolvimento das famílias no processo de inclusão.

Da metaetnografia às expedições etnográficas pelo nordeste do Brasil: Recursos e percursos para a atualização de fontes sobre devoções populares
Authors: Bonfim Luís Américo Silva
Published: October 2022

Este texto analisa a trajetória de uma pesquisa que envolveu práticas votivas e devoções populares no nordeste do Brasil. O estudo, originalmente uma tese de doutorado, teve como objetivo mapear e atualizar as expressões devocionais a partir de fontes bibliográficas produzidas por autores como Luís Saia, Luís da Câmara Cascudo, Alceu Maynard Araújo e Théo Brandão, entre outros. Na fase da revisão de literatura foi realizada uma análise qualitativa sobre obras selecionadas, numa perspectiva metaetnográfica, que atribuiu sentido não apenas aos dados registrados, mas à sua obtenção e condições críticas de escrita. A seguir, foi produzida uma síntese interpretativa e comparativa de alguns conceitos e categorias presentes nos textos, o que gerou um quadro de referências e alguns roteiros para a realização do trabalho de campo. Nesse estágio conclusivo, santuários e espaços devocionais foram visitados em todos os estados da região nordeste do Brasil, em viagens entre os anos de 2001-21. Como resultado, apresento uma confrontação entre as rupturas bibliográficas e a própria concreção do fenômeno religioso.

This paper describes a field study of the illumination and lighting energy use in a full-scale test office in a building located in southern Norway. Natural light is provided to the office via southwest-oriented windows and a horizontal light pipe (HLP) with a daylight entrance facing the south. The study is a full-scale field study, and it is a continuation of the recently published study addressing a scale model and a theoretical model. The novelty of this study is a custom-made reflector for the HLP’s daylight distribution to preserve the features of natural light noted as the primary human association with daylight. The main research aim was to determine if the daylighting level in the back of the office was improved as a consequence of the daylighting provision from the HLP compared to a reference situation without a HLP, as well as whether the lighting energy use for the electric lighting system that was supposed to provide the recommended light level was reduced. This study includes monitoring of the outdoor and indoor illuminance levels as well as the energy consumption of the luminaires throughout the study’s test period and a corresponding reference period. The recorded data were used to test hypothesis applying inferential statistical analyses. In conclusion, this paper reports an increased daylight level on the working area in the rear part of the office of approximately 200 to 300 lx during clear and sunny days at equinox. The increased daylight level on the working area near the window of approximately 50 lx was also recorded. These findings have important implications for energy balance in the Zero Energy Buildings (ZEB) and the ‘peak load’ for energy consumption.

[Extract from Foreword] This ‘cruise report’ is the first of a short series, reflecting the aspiration of the Clyde Fishermen’s Association to establish a rigorous sampling scheme to monitor changes in the abundance and distribution of cod (and later other gadoid species) within the Clyde area. The Scottish Oceans Institute was approached to provide independent scientific support in early 2016. A series of surveys was then conducted in 2016, 2017 and 2018. In each survey the SOI provided observers, collected data and wrote up a cruise report detailing the methods used and the location, numbers, weights, sex and maturity states of fish caught. Trials were halted after 2018 firstly because of pressing issues resulting from Brexit which absorbed any potentially available human and other resources, and secondly because of the COVID pandemic. The reports remained as unapproved and incomplete drafts until 2022. Picking up these reports again in 2022, we have responded to reviewers’ comments since made by Marine Scotland Science and have finalised all four reports in the 2016-2018 current series.

Альтернативою прямокутного растру, який отримав найбільшого поширення в засобах візуалізації інформації, є гексагональний растр, при якому піксел має форму правильного шестикутника.  Використання такого растру дає можливість підвищити роздільну здатність екранів, і , як наслідок, підвищити реалістичність формування графічних зображень. Використання гексагонального растру дозволяє замощувати площину екрану без розривів і накладань. Важливими геометричними особливостями гексагона є рефлекційна симетрія та шестизв’язність.
Відрізки прямих відносять до найпоширеніших примітивів, тому час формування графічних сцен в значній мірі залежить від часу формування векторів. В роботі наведено аналіз методів лінійної інтерполяції, який показав доцільність використання методу оцінювальної функції
Розроблено метод формування крокової траєкторії подвійними кроковими приростами.
Визначено типи можливих сполучень крокових приростів. Виведено формули для розрахунку оцінювальних функцій. Розглянуто особливості формування відрізків прямих для характерних ділянок, на які розбито координатний простір. Для підвищення точності формування крокової траєкторії запропоновано використовувати початкове значення оцінювальної функції, яке дозволяє симетрувати похибку всередині цифрового сегменту.
Запропоновано для формування крокових траєкторій відрізків прямих використовувати дві незалежні оцінювальної функції. Одна з них використовується для формування парних точок траєкторії, а інша – для непарних точок крокової траєкторії.
Наведено оцінки точності формування крокової траєкторії.
Запропоновані методи лінійного інтерполювання дозволяють до двох разів підвищити продуктивність лінійного інтерполювання.
