História e ficção
Authors: Alves Gomes Warley
Published: August 2021

O artigo busca aprofundar as relações entre História e ficção a partir do cruzamento entre categorias de funcionamento dos dois campos, jogando luz a aspectos poucas vezes refletidos sobre o campo historiográfico. Conjugando elementos de teóricos da História − como Hayden White e Frank Ankersmit – com autores que buscam refletir sobre o ficcional – Wolfgang Iser, Luiz Costa Lima e Jacques Rancière −, desemboca-se em uma reflexão sobre a História e a ficção que dialoga com concepções contemporâneas da ciência. A partir de um resgate do ficcional, recusa-se tanto uma abordagem exclusivamente cientificista da História, bem como uma perspectiva demasiado relativista.

Published: August 2021

The coastal area is a dynamic environment influenced by atmosphere, land, and ocean interactions. Similarly, the position of coastlines is also changing due to natural and human-induced components, for instance, erosion, wave, daily tide, storm, and coastal development. In literature, coastline position can be identified based on proxies such as coastal features identified from an aerial photo or very high-resolution image and tidal datum-based indicators extracting from a ground survey. This research proposed a method in deriving datum-based coastline by integrating various bathymetric data, including single beam and multibeam echo sounding data, the National Digital Elevation Model, the national bathymetry data, as well as satellite-derived bathymetry data. The stacked curve spline tension method was applied to assimilate those various bathymetric data, and finally, the coastline was generated. Based on the accuracy assessment conducted, coastline similarity accuracy varies; namely, the LAT coastline had an accuracy of 29.28%, the MSL coastline was 65.45%, and the HAT coastline was 47.48%. These variations are due to several reasons, including the lack of input data, the density of depth data that varies greatly, the difference in data acquisition time between the data used for the LPI map and the data used in this study. Although the accuracy values obtained were not sufficiently high, the proposed method was quite promising to adopt. The method can be used as an alternative for the coastline model and overcome data, time, and cost limitations in providing national coastlines
The Effect of Heat Treatment on Mechanical Properties of J4 Series Stainless Steel Metals
Authors: Priyotomo Gadang , Astawa I Nyoman Gede Putrayasa , Rokhmanto Fendy
Published: August 2021

J4 series stainless steel (SS) is austenitic alloy steel containing chromium and mangan, which has moderate strength and corrosion resistance. However, austenitic SS alloys generally undergo a sensitization process during heat treatment that decreases metal mechanical properties. The investigation of mechanical properties effect on J4 series SS toward the various temperature of metal was carried out at the temperature range of 600oC – 1050oC. The decrease of tensile strength, yield strength, and hardness are followed by increasing toughness and elongation in an increasing metal temperature up to 1050oC. This behavior of mechanical properties is caused by the transformation of α’-martensite phase to the austenitic phase with increasing heating temperature. On the other side, a significant decrease in toughness, yield strength, and elongation at the temperature of 700oC indicate a sensitization process on J4 stainless steel. The process of sensitization will correspond to the susceptibility of stress corrosion cracking on stainless steel.

This study discusses the effect of the number of blades on a horizontal flow propeller turbine performance on a small scale experimentally. The development of small-scale water turbines has made many advances, including water turbines with the horizontal flow. Water turbines in horizontal flow can be applied to irrigation systems, piping systems, the wastewater treatment channel, and other closed channels. Pengukuran dynamic head pada aliran horisontal berdasarkan nilai pressure drop atau perbedaan tekanan sebelum dan sesudah turbin. Dynamic head measurement on the horizontal flow is based on pressure drop values or pressure before and after the turbine. Static bulbs placed before the turbine aim to increase the speed of water flow and potentially improve turbine performance. This study aims to determine the effect of the number of blades on the performance and efficiency of propeller turbines. The blade angle used is 200 with a bulb ratio of 0.6 to the pipe diameter. The variations in the number of blades used were 4, 5, 6, and 7, with each tested at 7 L / s, 9 L / s, 11 L / s, and 13 L / s. The results of this study indicate the number of blades 5 with a discharge of 13 L / s shows the best turbine performance compared to the number of other blades, besides that the number of blades 5 with a flow rate of 13 L / s shows the best efficiency value of around 40%.

Qualitative Assessment of Cyber Risk Exposures in India
Authors: Doss Steward , Narasimhan Raveendran
Published: August 2021

Increased dependency on technology and data usage has simultaneously enhanced the risk exposures and vulnerabilities of organizations globally. This paper investigates this issue in India by analyzing the survey-based data we collect and provides a framework for qualitative assessment of cyber risks. The paper uses the Structural Equation Model (SEM) to validate the conceptual cyber-risk model that we have developed using the key-risk factors, such as the level of awareness, perceived risk likelihood, level of cyber-security, and cyber-risk exposures. The study results show that the risk vulnerability and the perceived risk likelihood have a positive impact on risk exposure, while risk awareness, cybersecurity, and control measures have a negative relationship. This study also identifies the causal factors among the exposures and the findings can help organizations prioritize their cybersecurity protection investments and caution insurers to take necessary mitigation measures for effective cyber-risk management and financing for their clients.
Design and Evaluation of a Novel Instrument Gripper for Handling of Surgical Instruments
Authors: Heibeyn Jan , König Nils , Domnik Nadine , Schweizer Matthias , Kinzius Max , Janß Armin , Radermacher Klaus
Published: August 2021

Introduction: Contaminated surgical instruments are manually prepared for cleaning and disinfection in the reprocessing unit for medical devices (RUMED). Manual labour exposes staff to the risk of infection and is particularly stressful at peak times due to the large volume of instruments. Partial automation of processes by a robot could provide a solution but requires a gripper that can handle the variety of surgical instruments. This paper describes the development and first evaluation of an instrument gripper. Methods: First, an analysis of gripping geometries on basic surgical instruments is carried out. Based on the identified common features and a review of the state of the art of gripper technology, the SteriRob gripper concept is developed. The concept is compared with a force closure gripper in a series of tests using seven criteria. Results: Both gripping approaches investigated can be used for handling surgical instruments in a pick-and-place process. However, the SteriRob gripper can transmit significantly higher acting forces and torques. In addition, the gripping process is more robust against deviations from the expected instrument position. Conclusion: Overall, it has been shown that the developed instrument gripper is suitable for about 60% of reusable surgical instruments due to the focus on horizontal cylindrical geometries. Because of the large possible force transmission, this gripping approach is particularly suitable for tasks in which the robot assists with cleaning processes.

Published: August 2021

Algorithms for automated analysis of intravascular ultrasound (IVUS) images can be disturbed by guidewires, which are often encountered when treating bifurcations in percutaneous coronary interventions. Detecting guidewires in advance can therefore help avoiding potential errors. This task is not trivial, since guidewires appear rather small compared to other relevant objects in IVUS images. We employed CNNs with additional multi-task learning as well as different guidewire-specific regularizations to enable and improve guidewire detection. In this context, we developed a network block which generates heatmaps that highlight guidewires without the need of localization annotations. The guidewire detection results reach values of 0.931 in terms of the F1-score and 0.996 in terms of area under curve (AUC). Comparing thresholded guidewire heatmaps with ground truth segmentation masks leads to a Dice score of 23.1 % and an average Hausdorff distance of 1.45 mm. Guidewire detection has proven to be a task that CNNs can handle quite well. Employing multi-task learning and guidewire-specific regularizations further improve detection results and enable generation of heatmaps that indicate the position of guidewires without actual labels.

Published: August 2021

Endovascular surgical robotics requires a facile and realistic testbed to validate control algorithms. This work compares methods to manufacture such a testbed. Utilizing animal tissue, a mannequin, and a low-voltage flow pump it is possible to perform catheter-based interventions with X-ray feedback for less than €300. The aim of this paper is to lower the entry hurdle for validating endovascular surgical robots by providing a method to build a facile and low-budget testbed.
Sequential U-Net Architecture for Automatic Femoral Artery Segmentation in Ultrasound Images
Authors: Estrada Lugo Ana , Bockelmann Niclas , Haxthausen Felix von
Published: August 2021

This work compares three different approaches to automatically segment the femoral artery from 2D ultrasound images. Two of the architectures follow a sequential structure, where each ultrasound image is considered a slice of the whole vessel volume, and its previous segmentation result will be part of the input, thus leading to a spatial prior. The Dice score on test data show a better performance on the baseline U-Net (0.819) compared to the sequential U-Net approaches (0.633, 0.725) for the femoral artery segmentation. This could be attributed to the misalignment of the slices being used in those networks. A possible improvement could be assumed in the implementation of a spatially calibrated and tracked ultrasound probe. Overall, these results indicate promising approaches for an automatic segmentation of the femoral artery using 2D ultrasound data.
Progress and Prospects: Sino-Russian Strategic Coordination in Multilateral Mechanisms
Authors: Sun Zhuangzhi
Published: August 2021

As China and Russia face a complex international and neighborhood environment with many uncertainties and real security threats, it is of special significance to strengthen cooperation within the multilateral framework at the regional and higher level, including leading the establishment of new regional cooperation mechanisms such as the Shanghai Cooperation Organization (SCO). China and Russia are interacting in global and regional frameworks such as the United Nations (U.N.), BRICS, G20, APEC, and the Conference on Interaction and Confidence-Building Measures in Asia, and jointly promoting cooperation between the Belt and Road Initiative and the Eurasian Economic Union. All of these add more connotations and richer levels of cooperation in the Sino-Russian comprehensive strategic partnership of coordination in the new era. The two countries share the same or similar views on many international and regional issues and have extensive common interests in security, economic and political fields, which is an important prerequisite and basis for multilateral cooperation. There are inevitable differences between the two major powers in goals on regional issues, yet those differences haven’t become substantial obstacles to multilateral cooperation. Looking forward, with the complex changes in the international situation, especially in the post-pandemic era when there will be significant adjustments in the economic, political and security landscape, close cooperation between China and Russia within multilateral mechanisms can play an increasingly important role in improving the global and regional governance system, maintaining multilateralism and steering the international landscape in a more just and rational direction.

Published: August 2021

The probabilistic characteristics of the graph ofk-fold iteration of uniform random mapping are studied. Formulas for the distribution of the length of the aperiodicity segment of an arbitrary vertex with some restrictions are calculated. We obtain exact expressions for the probabilities that two arbitrary vertices belong to the same connected component, that an arbitrary vertex belongs to the preimage set of another vertex and that there exists a collision in the considered graph.

Authors: Giang Nguyen Hong , Wang YuRen , Hieu Tran Dinh , Tho Quan Thanh , Phuong Le Anh , Tu Do Hoang Ngo
Published: August 2021

This study examines rainfall forecasting for the Perfume (Huong) River basin using the machine learning method. To be precise, statistical measurement indicators are deployed to evaluate the reliability of the actual accumulated data. At the same time, this study applied and compared two popular models of multi-layer perceptron and the k-nearest neighbors (k-NN) with different configurations. The calculated rainfall data are obtained from the Hue, Aluoi, and Namdong hydrological stations, where the rainfall demonstrated a giant impact on the downstream from 1980 to 2018. This study result shows that both models, once fine-tuned properly, enjoyed the performance with standard metrics of R_squared, mean absolute error, Nash–Sutcliffe efficiency, and root-mean-square error. In particular, once Adam stochastic is deployed, the implementation of the MLP model is significantly improving. The promising forecast results encourage us to consider applying these models with future data to help natural disaster non-stop mitigation in the Perfume River basin.

Numerical solutions for variable-order fractional Gross–Pitaevskii equation with two spectral collocation approaches
Authors: Doha Eid H. , Abdelkawy Mohamed A. , Amin Ahmed Z. M. , Lopes António M.
Published: August 2021

This paper addresses the numerical solution of multi-dimensional variable-order fractional Gross–Pitaevskii equations (VOF-GPEs) with initial and boundary conditions. A new scheme is proposed based on the fully shifted fractional Jacobi collocation method and adopting two independent approaches: (i) the discretization of the space variable and (ii) the discretization of the time variable. A complete theoretical formulation is presented and numerical examples are given to illustrate the performance and efficiency of the new algorithm. The superiority of the scheme to tackle VOF-GPEs is revealed, even when dealing with nonsmooth time solutions.
Error analysis for a vorticity/Bernoulli pressure formulation for the Oseen equations
Authors: Anaya Verónica , Mora David , Pani Amiya K. , Ruiz-Baier Ricardo
Published: August 2021

A variational formulation is analysed for the Oseen equations written in terms of vorticity and Bernoulli pressure. The velocity is fully decoupled using the momentum balance equation, and it is later recovered by a post-process. A finite element method is also proposed, consisting in equal-order Nédélec finite elements and piecewise continuous polynomials for the vorticity and the Bernoulli pressure, respectively. The a priori error analysis is carried out in the L2-norm for vorticity, pressure, and velocity; under a smallness assumption either on the convecting velocity, or on the mesh parameter. Furthermore, an a posteriori error estimator is designed and its robustness and efficiency are studied using weighted norms. Finally, a set of numerical examples in 2D and 3D is given, where the error indicator serves to guide adaptive mesh refinement. These tests illustrate the behaviour of the new formulation in typical flow conditions, and also confirm the theoretical findings.
Reproductive genetic screening for information: evolving paradigms?
Authors: Leonard Samantha J.
Published: August 2021

Reproductive genetic screening has introduced the possibility for pregnant women to learn, during the pregnancy or sometimes earlier, about the likelihood of their baby being affected with certain genetic conditions. As medicine progresses, the options afforded by this early information have expanded. This has led to a shifting paradigm in prenatal screening, wherein the early knowledge is seen as useful not solely for its inherent value to the pregnant woman, but also as enabling an expansion of conditions whose identification may allow early intervention and clinical impact. This article discusses this paradigm against the backdrop of prenatal genetic screening that is available today.
Comparison of single- and triple-port VATS for lung cancer: A meta-analysis
Authors: Gao Yunfei , Abulimiti Abulaiti , He Dan , Ran Anpeng , Luo Dongbo
Published: August 2021

Objective

To compare the perioperative parameters between single- and triple-port video-assisted thoracoscopic surgery (VATS) lobectomy in the treatment of lung cancer.

Methods

The Pubmed, Embase, Cochrane library, and the Web of Science databases were electronically searched from inception to September 2019 for all relevant studies. Study quality was evaluated using the Jadad scale or the Newcastle-Ottawa scale. The results were pooled using the generic inverse-variance method and expressed as mean differences or risk ratios, with 95% confidence intervals.

Results

Three randomized controlled trials (RCTs) and ten cohort studies with 2,278 subjects were included in the meta-analysis. Whether based on RCTs or cohort studies, the pooled results showed no significant difference in the operation time, chest tube duration, intraoperative blood loss, postoperative hospital stays, lymph node dissection number, postoperative drainage volume, and postoperative complications between single- and triple-port VATS lobectomy (P > 0.05). Single-port VATS could relieve postoperative pain better than triple-port VATS, especially in the first day and fifth day (P < 0.05). No evidence of significant publication bias was found (P > 0.05).

Conclusion

Single-port VATS lobectomy can yield similar perioperative results to those of triple-port VATS lobectomy and is more effective in relieving postoperative pain.

Published: August 2021

Photothermal imaging is useful for detecting individual nanoparticles and obtaining the absorption spectra. This study presents a wide-field photothermal reflectance spectroscopy technique achieved by incorporating a pump beam, a probe beam, and a charge-coupled device (CCD) camera into a commercial microscopic setup. The presented design does not require precise alignment between the pump and the probe beams and enables the observation of numerous individual nanoparticles during image acquisition. Despite the use of a simple imaging processing method, i.e., a four-bucket method using a CCD camera, sufficient sensitivity for the spectral imaging of a single gold nanorod (20 nm diameter and 84 nm length) is demonstrated. Numerous individual nanoparticles within a wide field of view (240 μm × 180 μm) are detected in an image captures at an imaging measurement speed of 0.02 mm2 min−1. Furthermore, the proposed photothermal reflectance spectroscopy technique can detect the variation in the absorption peak of the measured spectra depending on the aspect ratio of individual nanoparticles within a spectral resolution of 1 nm.
Historical pigments, dyes and binders
Authors: Gärtner Magdalene
Published: August 2021

Artistic creation has accompanied the development of mankind since the beginning. Color as the appearance of things perceptible with the eye is fundamental for the creative process. For the longest time in the past, the use of color was characterized by often very complex manufacturing processes that required the greatest inventiveness and complex knowledge of comprehensive interrelationships from the user. Existing knowledge was passed on and used again and again, but the basic color materials were always further developed and sensitively adapted to the differentiated areas of application and needs. Today, paint coats and, in some cases, extensive collections of recipes provide us with evidence and ideas about these processes in previous times. In this context, it is important to understand that paint recipes were treated like valuables and secrets in the past. The present overview offers insights into the world of historical pigments, dyes and binders. However, a complete overview is not possible at this point due to the diversity of sources, the individual work processes and the different application requirements.
Cuba y China enlazadas por un mismo ideal: su cultura
Authors: Jacomino Ruiz Alegna
Published: August 2021

El presente estudio devela los lazos culturales que unen a los pueblos de Cuba y China. Tomando por base las relaciones históricas que han mantenido ambas naciones y focalizando en particular en los similares posicionamientos ideológicos que comparten respecto a la cultura, se concluye que la cultura socialista constituye una prioridad central para las presidencias de ambos países, y un elemento de hermanamiento dinámico de ambos pueblos. En el año actual, 2021, se cumple el 60 aniversario de aquel memorable discurso pronunciado por Fidel Castro Ruz conocido como Palabras a los intelectuales, el cual sirvió de plataforma programática para la concepción definitiva de la Política Cultural Cubana que aún hoy se mantiene vigente. Llama la atención el hecho de que el presidente de China, Xi Jinping, evoque con vehemencia en sus discursos asuntos medulares para el futuro de la nación, de una manera que engarza armoniosa e indiscutiblemente, no solo con las pautas sentadas por Fidel Castro, sino con las prioridades que se plantea el actual presidente cubano Miguel Díaz-Canel para su gobierno. El conocimiento de estas coincidencias, ya sean necesarias o casuales, permitirá sin duda ayudar a desentrañar los ideales que identifican a cada una de estas culturas.
Verteidigung ist Pflicht – Deutschlands außenpolitische Kultur muss strategisch werden – Teil 1
Authors: Giegerich Bastian , Terhalle Maximilian
Published: August 2021

Kurzfassung

Der Aufstieg oder Wiederaufstieg revisionistischer, repressiver und autoritärer Mächte bedroht die westliche, durch die USA garantierte internationale Ordnung, die den Aufstieg und die Sicherheit der Bundesrepublik Deutschlands nach dem Zweiten Weltkrieg gewährleistet hat. Zu einem Zeitpunkt, wo die USA zunehmend durch den Aufstieg Chinas in Asien absorbiert sind (wobei ein Krieg zwischen China und den USA nicht ausgeschlossen werden kann), muss Europa in der Lage sein, sich im Rahmen der NATO gegen eine konventionelle Aggression Russlands weitgehend alleine zu verteidigen. Dabei sind substantielle Beiträge Deutschlands unersetzlich. Jahre der Vernachlässigung und der strukturellen Unterfinanzierung haben jedoch die deutschen Streitkräfte ausgehöhlt. Die politische Führung in Berlin tut sich schwer, diese neue Lage und die Dringlichkeit einer Neuausrichtung der deutschen Verteidigungspolitik zu akzeptieren.

Conventional Repair of an Intraoperatively Diagnosed Congenitally Corrected Transposition of the Great Arteries in an Adult
Authors: Putra Muhammad Arza , Sukardi Rubiana , Grantomo Jonathan , Pratita Jenni
Published: August 2021

Background: Congenitally corrected transposition of the great arteries (ccTGA) is a rare condition that accounts for just 1% of all congenital heart disease. Diagnosis of ccTGA often is missed in adulthood, despite imaging and cardiology consultation.
Case report: We present the case of an intraoperatively diagnosed ccTGA with severe tricuspid valve regurgitation and secundum atrial septal defect in a 54-year-old woman, who preoperatively was diagnosed with mitral valve regurgitation in atrioventricular and ventriculoarterial concordance heart. Intraoperatively, options considered were anatomical repair with atrial-arterial double switch operation after retraining the left ventricle or a conventional repair that focused on the associated defects without addressing the discordant connections. Considering our patient’s age and condition, we decided to carry on with the conventional repair to prevent further systemic right ventricle dysfunction that may lead to poor outcome and decreased survival. She was discharged one week after surgery and resumed her normal activity at 3-month follow up.
Conclusion: Although it rarely happens, CHD such as ccTGA in an adult must always be considered. Careful examination is essential. The treatment of ccTGA in an adult is challenging, with more limited options compared with pediatric patients. However, early management could still provide favorable outcomes.
Prediction of the Length of Intensive Care After Cardiac Surgery Under Cardiopulmonary Bypass: Logistic Regression Analysis Based on Troponin I And EuroSCORE II
Authors: Tai Wan Gu Tai Lai Ti , Wu Jianjiang , Zhan Haiting , Huang Yidan , Wang Jiang
Published: August 2021

Aim: This study is to establish a model for patients undergoing cardiac surgery under cardiopulmonary bypass (CPB) to predict the length of intensive care.
Methods: This is a single center retrospective study. A total of 265 patients admitted to the ICU after CPB from 2016 to 2017 were enrolled in the study. Preoperative indicators, intraoperative parameters, and postoperative data were collected. Each patient was scored for EuroSCORE II before surgery. According to the length of intensive care, all patients were divided into two groups: short stay (< 72 h) and long stay (≥ 72 h). A binary logistic regression analysis was performed to establish a regression model to evaluate the predictive performance of the indicators and the EuroSCORE II scoring system on the length of the intensive care.
Results: Both troponin I and EuroSCORE II could predict the length of intensive care of patients undergoing cardiac surgery under CPB. After combing the two factors, the prediction efficiency was higher. Comparing the prediction results with the actual data, it showed that the method had high overall accuracy.
Conclusions: The predictive model based on cTnI and EuroSCORE II can accurately predict the length of intensive care of patients undergoing cardiac surgery under CPB. This predictive model may help to improve ICU resource management.
Rosai-Dorfman disease: a rare presentation of extranodal involvement of isolated bone. Case report
Authors: García-Prada Camilo Andrés , Rodríguez-Yanez Tomás , Ferrer-Santos Carlos Alberto
Published: August 2021

Introduction: Rosai-Dorfman disease (RDD), also known as sinus histiocytosis, is a rare disorder characterized by histiocyte proliferation.
Case presentation: A 33-year-old man consulted the emergency department of a tertiary care institution in Cartagena de Indias, Colombia, due to a 6-month history of progressive deformity in the frontal right side of the face, associated with pain of slow progression, without any other symptoms or dermatological involvement. There were no other major findings on physical examination and laboratory tests performed were negative. Imaging scans obtained showed extensive inflammatory involvement of the frontal bone, which led to suspect osteomyelitis as the first diagnostic possibility. A biopsy of the lesion was performed with negative cultures for bacteria, which allowed establishing a diagnosis of extranodal Rosai-Dorfman disease with isolated bone involvement. Treatment with systemic corticosteroids was indicated with poor response, so methotrexate was added, achieving an evident improvement after 2 months.
Conclusions: Little is known about the manifestations of Rosai-Dorfman disease and its treatment in the adult population. The present case report contributes to expanding the literature on this topic, which can present with rare symptoms that may pose challenges for its diagnosis.

Verifica, também, a trajetória de desenvolvimento dos meios marcada pela convergência tecnológica, as novas funções do leitor e a formação de uma linguagem específica a partir dessas características, e a possibilidade de fusão conceitual operada pela hipermídia.
Memória viva das ciências da comunicação
Authors: De Assis Francisco
Published: August 2021

O campo científico da comunicação talvez seja a arena mais controversa entre as ramificações da ciência. Refutado por diferentes níveis hierárquicos dentro do sistema formal de produção acadêmica, a área teve, em várias ocasiões e especialmente no Brasil, sua própria legitimidade colocada à prova. "Afinal, comunicação é ciência?", questionam os apocalípticos (e até mesmo alguns integrados, para citar Umberto Eco), pondo em dúvida o real valor do saber gerado nesse eixo.

O II Simpósio Nacional da ABCiber abrigou mais de 130 palestras, distribuídas em quase 50 painéis temáticos (científicos e de arte digital), formados a partir das respostas da comunidade científica ao Call for papers institucional. Igualmente, o evento somou, além de quatro plenárias especiais, 25 conferências ministradas por membros(as) da Diretoria e do Conselho Científico Deliberativo da Associação, e realizadas em dez mesas, nos três primeiros dias. O leitor tem em mãos, nesta edição da Famecos, um conjunto representativo das argumentações levadas a debate público nessas mesas. Os artigos - posteriormente submetidos à avaliação editorial de praxe e que, tanto mais por isso, justificam per se a sua riqueza textual - expressam o estado da arte de um conjunto significativo de pesquisas em desenvolvimento em Programas de Pós-Graduação brasileiros em diferentes áreas das Ciências Humanas e Sociais Aplicadas, em especial a Comunicação.

Cel badań: Istotne w rozwoju umiejętności numerycznych (m.in. porównywania liczb czy szacowania liczebności zbiorów) są takie funkcje poznawcze, jak m.in. pamięć i uwaga. Zaburzeniem związanym z trudnościami w nabywaniu podstawowych umiejętności arytmetycznych jest dyskalkulia. Znaczną część wskaźników poznawczych związanych z operowaniem materiałem numerycznym można oceniać używając Skali Inteligencji Wechslera dla Dzieci (WISC-R). Celem badania było sprawdzenie korelacji między poziomem inteligencji i poziomem bazowych umiejętności numerycznych.
Metody badań: Grupa 22 dzieci w wieku od 7 do 8 lat wzięła udział w badaniu, w którym sprawdzano związek między wysokością wyników uzyskanych w podskalach WISC-R oraz wykonaniem zadań, które pozwalają na pomiar bazowych umiejętności numerycznych – szacowania, porównywania liczb oraz operowania mentalną osią liczbową (w zakresie 1–9), mierzonych testem Prokalkulia 6-9.
Wyniki badań: Wyniki wykazały, że dzieci przejawiające większą trudność w szacowaniu miejsca liczb na osi mają również niższy iloraz inteligencji. Z poziomem wykonania takich zadań koreluje dodatnio m.in. poziom inteligencji słownej. Mniejsza dokładność w szacowaniu miejsca liczb na osi bez podziałki wiąże się z mniejszą liczbą punktów uzyskanych w podskali Arytmetyka, a związek ten dotyczy przede wszystkim liczb ze środka osi liczbowej (od 4 do 6). Wykonanie podskali Arytmetyka jest również tym, co koreluje najsilniej z poziomem bazowych umiejętności matematycznych. Badanie ujawniło też związek między liczbą punktów w podskali Powtarzanie Cyfr i wykonaniem części zadań testu Prokalkulia 6-9 – wyższy wynik w tej podskali wiąże się z lepszym szacowaniem liczebności zbioru oraz bardziej poprawnym porównywaniem liczb prezentowanych w różnych formatach.
Wnioski: Wyniki te sugerują, że umiejętności matematyczne korelują z niektórymi aspektami inteligencji (zwłaszcza z tymi wspierającymi zdolności wzrokowo-przestrzenne), a więc także wskazują na użyteczność WISC-R w procesie diagnozy dyskalkulii.
Berta Zuckerkandl i krytyka artystyczna polskiej sztuki (na wybranych przykładach)
Authors: Świdnicka Katarzyna
Published: August 2021

Cel badań. Celem badań jest przedstawienie poglądów Berty Zuckerkandl dotyczących polskiej sztuki w jej tekstach prasowych.

Metoda badań. Metodami użytymi podczas badań są te właściwe dla dyscypliny literaturoznawstwa, historii sztuki, metoda „skoposu”, aparatu tłumacza.

Wyniki badań. Rozeznanie w tekstach Berty Zuckerkandl o sztuce polskiej nie jest wystarczające. Teksty nie zostały przetłumaczone i zanalizowane.

Wnioski. Berta Zuckerkandl jako jedyna z wielkich krytyków artystycznych swojego czasu poświęciła tak wiele miejsca sztuce polskiej. Jej znajomość sztuki, artystów i kultury polskiej jest niezwykle szeroka. Wynosi ona sztukę polską, stawia na równi z innymi artystami i analizuje ich dzieła.
33 omdlenia – pierwsza krakowska adaptacja teatralna rosyjskiej klasyki po 1989 roku
Authors: Karlikowska-Pąsiek Magdalena Małgorzata
Published: August 2021

Cel badań. Celem badań było sprawdzenie, które wątki trzech dramatów Antoniego Czechowa (Niedźwiedź, Oświadczyny, Jubileusz) polski reżyser pominął lub zmienił i jaki jest tego efekt dla pierwszej krakowskiej adaptacji teatralnej tychże utworów po 1989 roku jako całości.

Metoda badań. Przedmiotem badań był scenariusz Tadeusza Pawłowicza wystawiony w krakowskim teatrze Bagatela 8 kwietnia 1989. W pracy został przeanalizowany polski scenariusz adaptacji utworów: Niedźwiedź, Oświadczyny oraz Jubileusz. Jedna z hipotez zakłada, że przenoszenie dzieł literackich z jednej formy do drugiej (dzieło literackie – teatr) i z jednej kultury do drugiej (Rosja – Polska) wiąże się z utratą niektórych wątków. Ponadto warto również wspomnieć, że wraz z transformacjami ustrojowymi po 1989 roku w polskim teatrze zaszedł szereg zmian związanych z repertuarem oraz ich funkcjonowaniem. Nowa powstała rzeczywistość wygenerowała nowe możliwości, wyzwania a także problemy, które wpłynęły na kształt inscenizowania literatury klasycznej, w tym rosyjskiej.  

Wyniki badań. Analiza wykazała, że Tadeusz Pawłowicz przenosząc dzieło literackie z jednej formy do drugiej (dzieło literackie – teatr) i z jednej kultury do drugiej (Rosja - Polska) dokonał marginalnych skreśleń, pozostając tym samym wierny tekstowi Czechowskich utworów oraz nie dopisał dodatkowych, autorskich partii teksu. Ponadto reżyser realizując 33 omdlenia powielił pomysł na połączenie trzech wodewili Czechowskich w jedną inscenizację, Wsiewołoda Meyerhold z 1935 roku.

Wnioski. W badaniu zostały wzięte pod uwagę aspekty przekładu dzieła literackiego na dzieło sceniczne. Badanie modyfikacji treści oryginalnego tekstu oraz przekładu nie ma na celu oglądu spostrzeżeń polskiego widza. Uzyskane wyniki przedstawiają jedynie możliwości odkodowania i zrozumienia najważniejszych wątków utworów, jaką widzowi daje reżyser.
Logiczne myślenie w uczeniu się matematyki – zadania otwarte i zamknięte
Authors: Borowiecka Agnieszka
Published: August 2021

Cel badań. Celem badania było sprawdzenie poziomu logicznego myślenia uczniów, którzy ukończyli pierwszy etap edukacyjny.
Metoda badań. Wśród uczniów rozpoczynających naukę w klasie IV na terenie miasta Częstochowy i powiatu częstochowskiego przeprowadzono test w zakresie logicznego myślenia. Test składał się z 10 zadań zamkniętych, jednokrotnego wyboru. Zadania obejmowały treści matematyczne, praktyczne, analizę sytuacji i treści językowe. Za poprawną odpowiedź uczeń  otrzymywał jeden punkt, a za złą odpowiedź lub jej brak zero punktów.
Wyniki badań. Uczniowie mają problem ze zrozumieniem treści zadania i dokonaniem jego analizy. Niejednokrotnie błędnie dobierali także metody rozwiązania zadań. Uczestnicy badania lepiej radzili sobie z rozwiązaniem zadań otwartych niż zadań zamkniętych. Poziom logicznego myślenia po zakończeniu pierwszego etapu edukacyjnego nie jest zadowalający.
Wnioski. Matematyka jako przedmiot szkolny towarzyszy uczniom na każdym etapie edukacji. Wiedza z jego zakresu jest weryfikowana już po ukończeniu pierwszego etapu nauczania podczas tzw. „trzecioteściku”, po ukończeniu szkoły podstawowej podczas egzaminów ósmoklasisty oraz po ukończeniu szkoły średniej podczas egzaminu maturalnego. Z opracowanych wyników badań wynika, iż osiągnięcia matematyczne uczniów zależą od poziomu sprawności umysłowej, a głównie od umiejętności logicznego myślenia. Przeprowadzony test wykazał także, że dla większości uczniów matematyka jest wyzwaniem, wymaga bowiem rzetelności, umiejętności analizowania, dochodzenia do wniosków i przede wszystkim logicznego myślenia.
AUTOAGRESYWNY WZORZEC ADAPTACJI A CZYNNIKI OSOBOWOŚCI HEXACO
Authors: Panek Antonina , Żyżelewicz Barbara , Krajniak Anna , Franczak Arletta
Published: August 2021

Cel. Celem artykułu jest przedstawienie związku między autoagresywnym wzorcem adaptacji a czynnikami osobowości HEXACO. Autoagresywny wzorzec adaptacji to nabyty sposób reagowania na otaczające jednostkę środowisko. Charakteryzuje się reakcjami agresywnymi skierowanymi wobec własnej osoby. Jest powiązany z antyspołecznym zaburzeniem osobowości oraz zaburzeniem borderline.
Metody Badań. Do przeprowadzenia badań wykorzystano Kwestionariusz Osobowości HEXACO-60 (Ashton, Lee, 2007) oraz Kwestionariusz Jaka/Jaki Jesteś? (Łoś, 2013). Przebadano 330 osób w wieku 18–40 lat.
Wyniki. Wykazano, że autoagresywny wzorzec adaptacji istotnie statystycznie koreluje z takimi czynnikami osobowości jak: uczciwość, ekstrawersja, ugodowość i sumienność (wszystkie negatywnie) oraz emocjonalność (pozytywnie). Nie stwierdzono istotnych związków z otwartością.
Wnioski. Autoagresywny wzorzec adaptacji charakteryzuje się układem czynników, który może powodować gorsze przystosowanie społeczne jednostki. Uzyskane wyniki mogą zostać wykorzystane w praktyce klinicznej, wychowawczej i socjalnej, poprawiając jakość życia osób o takiej charakterystyce oraz zwiększając szanse na wczesne wykrycie ewentualnych zaburzeń u adolescentów. Ograniczeniem metody była mała ilość osób badanych w wieku dojrzewania, ze względu na utrudniony dostęp do tej grupy wiekowej (ograniczenia prawne wynikające z niepełnoletności respondentów, mniejsza ilość połączeń społecznych z tą grupą wiekową).
Brak. Edukacja w zamętach i odmętach
Authors: Kobylarek Aleksander
Published: August 2021

Artykuł  podejmuje problem redefinicji najważniejszych priorytetów edukacji w świecie pandemicznym i postpandemicznym. Według autora pandemia obnażyła braki w zakresie wartości naczelnych w obszarze edukacji. Diagnoza sprowadza się do przeładowania treściami programów kształcenia oraz nadmiernej szczegółowości, która powoduje, że zostały utracone (lub odeszły na dalszy plan) najważniejsze cele edukacji, jakimi są rozwój intelektualny, dbałość o środowisko, trenowanie umiejętności radzenia sobie w życiu. Krótka lista najważniejszych priorytetów zaczyna się od edukacji obywatelskiej, gdyż nieodpowiedzialność jest przyczyną niewłaściwych wyborów w każdej sferze, poprzez kompetencje kluczowe do edukacji ekologicznej. Artykuł podejmuje również problem słabości pedagogiki i wpływu jej niskiej pozycji wśród innych nauk na niedowartościowanie edukacji i rozwoju.   Według autora wartość pedagogiki i edukacji w społeczeństwie jest ściśle skorelowana z dobrobytem tego społeczeństwa i jakością życia obywateli.
