The consumption of pornography in adolescents and young people: a gender perspective analysis of the characteristics and profiles of consumers
Authors: Díaz Hernández Cristian , Torrado Martín-Palomino Esther , Gutiérrez Barroso Josué
Published: December 2023

The concept of new pornography refers to those pornographic contents easily available on the Internet, free and unlimited. The general objective of this article is to analyze the consumption of new pornography by young people and adolescents, determining the profile and analyzing the characteristics of the people who consume it. For this, it is based on a study carried out during the year 2020 in Tenerife (Spain) to a total of 2,432 young people and adolescents, of which 49.6% were women and 50.4% were men aged between 15 and 30 years. The methodology used replicated that of the research carried out by Dr. Ballester, professor of the University of the Balearic Islands, based on a questionnaire that collected sociodemographic data, the affective sexual education received and the consumption of pornography in the last month. The results show, on the one hand, that consumption is carried out mainly by young men (70.3% compared to 24.7% of women) who solve their sexual doubts through the Internet and share it with their friends. On the other hand, regarding the characteristics of the consumers, it is mostly a weekly or daily consumption and that they share it with friends. Both in Dr. Ballester's work and in this one, as well as in other national and international studies, there are coincidences in the results. The consumption of pornography by young people has consequences that must be analyzed in depth, although studies already point out the repercussion it has on the increase in sexual violence and the demand for prostitution. So, pornography is a school of inequality where young men and adolescents are socialized into violent attitudes towards women.

Published: December 2023

Desde hace algunos años, la Nueva Pornografía Online (NPO) se ha convertido en uno de los temas centrales del debate sobre la socialización de adolescentes y jóvenes, al menos en lo que se refiere a las relaciones interpersonales. Se sabe que el nivel de consumo no ha dejado de crecer, desde la generalización de las tecnologías 4G. También se conocen buena parte de las consecuencias de dicho consumo, en especial cuando supera determinados límites. Finalmente, cada vez se conoce mejor el negocio capitalista que promueve la pornografía, en conexión con el sistema prostitucional. Hasta ahora la investigación se ha basado principalmente en el consumo de pornografía por parte de los hombres, que era la población que accedía a la pornografía en mayor porcentaje y son muy escasos los estudios que analizan el consumo por parte de la población femenina. En el presente trabajo se presenta el estudio diagnóstico sobre el acceso consumo e impactos de la pornografía distribuida en internet, tanto en las relaciones interpersonales como sociales, centrado en las mujeres adolescentes de las Illes Balears. Se analiza la influencia de la pornografía sobre las percepciones, actitudes y conductas de las adolescentes y se discuten los resultados desde la perspectiva feminista.

Published: December 2023

The study evaluated the repeatability of the superovulatory response in 12 Australian Merino ewes during the breeding season in one (G1), three (G2), and four (G3) consecutive years. A modified protocol was used based on 200 mg pFSH in eight decreasing doses (12-h intervals) and supportive strategies such as changing the CIDR at day 7, spraying the horns with heparinized saline during the procedure, and use of Flunixin Meglumine. No significant differences were found in the total number of structures recovered during the years of application of the superovulation protocol (G1=8±2, G2=18±3, G3=19±4; p>0.05). High repeatability was observed, both for the total number of embryos and for the number of transferable embryos in G2 and G3. Superovulatory treatment for 3 and 4 successive years did not affect the efficacy of embryo retrieval.

Authors: Šaltytė Laura , Dučinskas Kęstutis
Published: December 2023

In this paper we propose modeling technique, which was applied to multivariate time series data that correspond to different spatial locations (spatial time series). ARIMA model class is considered for each location. Forecasting model for new location is built by spatial "connection" of identified models in observed locations. Spatial "connection" is implemented by spatial averaging of the coefficients of mod­els and by ordinary kriging procedure for means. This modeling technique is illustrated by a substantive example using R system.

Prompting Metalinguistic Awareness in Large Language Models: ChatGPT and Bias Effects on the Grammar of Italian and Italian Varieties
Authors: Massaro Angelapia , Samo Giuseppe
Published: December 2023

We explore ChatGPT’s handling of left-peripheral phenomena in Italian and Italian varieties through prompt engineering to investigate 1) forms of syntactic bias in the model, 2) the model’s metalinguistic awareness in relation to reorderings of canonical clauses (e.g., Topics) and certain grammatical categories (object clitics). A further question concerns the content of the model’s sources of training data: how are minor languages included in the model’s training? The results of our investigation show that 1) the model seems to be biased against reorderings, labelling them as archaic even though it is not the case; 2) the model seems to have difficulties with coindexed elements such as clitics and their anaphoric status, labeling them as ‘not referring to any element in the phrase’, and 3) major languages still seem to be dominant, overshadowing the positive effects of including minor languages in the model’s training.

Published: December 2023

The article presents the results of a study of anxiety states among Ukrainians during war after watching news in the media. Particular attention is paid to the study of assessing the level of situational (reactive) anxiety using the Spielberg-Khanin method. An analysis of theoretical studies and publications is presented that the revision of news in the media has a significant impact on the occurrence of anxiety in people. The rationale for the criteria for human anxiety states is given. The types of anxiety disorder whose symptoms include anxiety and causeless fear are substantiated. Three groups of respondents were identified that are qualitatively different from the general group of respondents in terms of the level of situational anxiety and have a significantly lower chance of developing anxiety disorders and phobias, despite age, gender, and revision of a negative media product. It is noted that the realization of creative potential is one of the preventions of the occurrence of excessive anxiety, fears and phobias. A number of preventive measures are presented aimed at reducing both the level of situational anxiety and the progress of various anxiety states in general.

Published: December 2023

The problem of gastroesophageal reflux disease (GERD) remains one of the most relevant in modern gastroenterology. In recent decades, there has been a tendency to increase in the incidence of GERD especially among young people. Symptoms of GERD occur in almost half of the adult population. The main symptom of GERD — intermittent heartburn, which significantly reduces the quality of life, noted in up to 40% of residents of industrialized countries. However, the real prevalence of GERD in the population has not been studied enough due to the low rate of medical treatment seeking, frequent asymptomatic course as well as the course of the disease under masks, the so-called «esophageal» manifestations. At the same time, the number of patients with GERD with combined pathology is growing. One such disease is autoimmune thyroiditis (AIT). AIT — is one of the most common diseases of the thyroid gland. Autoimmune inflammatory process in the thyroid gland leads to the constant production of autoantibodies to thyroperoxidase or thyroglobulin and further leads to permanent destruction of the thyroid gland with the subsequent development of hypothyroidism. Early diagnosis of AIT allows to timely treatment and maintains thyroid function. Both of these diseases have several common pathogenetic mechanisms, the main of which are thyroid hormones that regulate motility and secretion of the gastrointestinal tract. The comorbid course of these pathologies aggravates and modifies the clinical picture each other. For today, the role of thyroid hormones in the mechanism of formation of motor-secretory disorders in patients with GERD with concomitant AIT, their impact on the peculiarities of the formation of psychosomatic status, as well as gender features of GERD and AIT remains unexplored.

Authors:   Kharkiv National Medical Univercity, Pankova O.A. , Korzh O.M. ,   Kharkiv National Medical Univercity
Published: December 2023

Objective. To investigate the peculiarities of home blood pressure monitoring parameters in patients with essential hypertension (EH) in combination with type 2 diabetes mellitus (T2DM) and to evaluate their relationships with plasma catestatin (CTS) and relaxin-2 (RLN-2) levels. Materials and methods. 106 patients with EH, 55 of whom had comorbidity T2DM, and 30 healthy volunteers were enrolled in the study. Each patient underwent a comprehensive clinical examination, including measurement of systolic (SBP) and diastolic (DBP) blood pressure. Each study subject carried out home blood pressure monitoring for 31 days with the further registration of indicators in a diary. The levels of CTS and RLN-2 were determined by the enzyme-linked immunosorbent assay. Statistical data analysis was performed using the SPSS 25.0 statistical software. Results. CTS levels were reduced in patients with high normal SBP and arterial hypertension (p<0.001). There were revealed significant negative correlations of CTS levels with home blood pressure monitoring parameters (p<0.05). In patients with levels of RLN-2≥4.69 pg/ml, there were observed higher SBP (p<0.001) and DBP (p<0.05) parameters, except average and morning DBP. Conclusions. The decrease in CTS levels in EH and established correlations between CTS and home blood pressure monitoring parameters allow us to consider CTS as a biomarker of EH, especially EH with T2DM.

Authors:   Institute of Software Systems NAS of Ukraine, Doroshenko А.Yu. , R.V. Kushnirenko ,   Institute of Software Systems NAS of Ukraine
Published: December 2023

This paper briefly describes examples of how deep learning can be applied to geoscientific problems, as well as the main difficulties that arise when scientists apply this technique to the problems of meteorological forecasting. This paper aims at comparing the two most popular types of recurrent neural network architectures, namely the long short-term memory network and the gated recurrent unit when they are used to improve 2m temperature forecast results obtained using numerical hydrodynamic methods of meteorological forecasting. An efficiency comparison of architectures of recurrent neural networks was performed using the root-mean-square error. It is shown that all models with gated recurrent units are more efficient than models with long short-term memory. Thus the best architecture of recurrent neural networks for solving the problem of improving numerical meteorological forecasts has been revealed.

Published: December 2023

The article deals with the development of a software solution for the application of neuroevolution algorithms when creating a controller for controlling a robotic arm. The main principles of the neuroevolutionary approach for training neural network controllers in tasks requiring reinforcement learning are considered. In particular, the advantages of the adaptive approach are determined for a wide class of scenarios in which the working limb can work: implementation of stable grasping, positioning, manipulation of objects. It is noted that the final result of neuroevolution is an optimal network topology, which makes the model more resource-efficient and easier to analyze. The paper considers a software system that provides the developer with all the necessary tools for modeling the behavior of a robotic agent in environments of various levels of complexity: both two-dimensional and three-dimensional. In addition, the possibility of specifying the state of the agent not only as a set of data from sensors, but also as an image of the current environment from the camera is considered. According to the results of the experiments, the high efficiency of the search for the best solution using the NEAT algorithm is noted. It has been established that the proposed solution allows productively obtaining an effective policy in the form of a neural network, which has a minimal configuration, which will allow to increase the speed of the controller, which is critical for the operation of a real system. Thus, the use of a software solution for the adaptive development of a neuroevolutionary controller for solving tasks with a robotic limb allows to increase the efficiency of the learning process and obtain an optimal network topology.
Eu, Ota, rio de Hiroshima o dia que virou noite, de Jean-Paul Alègre
Authors: Grazioli Fabiano Tadeu
Published: December 2023

No artigo, investiga-se o texto dramatúrgico Eu, Ota, rio de Hiroshima: o dia que virou noite, do francês Jean-Paul Alègre, publicado no Brasil em 2020. Por meio de uma pesquisa bibliográfica de abordagem qualitativa, aproximam-se considerações teóricas de sua temática, bem como da sua estrutura, considerando o gênero dramático. Na primeira parte, coloca-se a peça em diálogo com pressupostos de Walter Benjamin (1985) sobre a necessidade de se fazer um contraponto ao discurso historicista, além de discutir-se brevemente aspectos relacionados à leitura literária e à juventude por meio dos estudos de Michèle Petit (2013), Freddy Gonçalves da Silva (2021) e Sara Bertrand (2021). Na segunda parte, considerando o amplo escopo da dramaturgia, parte-se da história dos livros na interface com a leitura, observando coordenadas de Roger Chartier (2002) em diálogo com os pressupostos sobre o palco imaginário, tema específico da leitura da dramaturgia, aqui abordado a partir de Jean-Pierre Ryngaert (1996, 2013). No caso do texto em análise, as rubricas desempenham função decisiva e são analisadas a partir de Patrice Pavis (2007), Anatol Rosenfeld (2002) e Marta Morais da Costa (2016). Ao final, atesta-se que, no caso do texto em análise, o suporte impresso dá conta da estrutura da dramaturgia, que coloca rubricas e diálogos em simbiose, possibilitando arquitetar as cenas no palco imaginado, em um estímulo contínuo à atualização das cenas nesse espaço caro à dramaturgia. Ainda, é louvável como o texto cênico, ou seja, as rubricas, trabalha a favor da construção do referido palco, de modo a não sabotar a estrutura da dramaturgia, mas assumindo-a de modo amplo e até complexo, fazendo o leitor, por meio dela, chegar às estruturas imaginativas de que se fala.
Dieulafoy's lesion, the endovascular approach as a therapeutic option when endoscopic treatment has failed: A case report and brief review
Authors: Hayashi-Mercado César , González-Urueta Miguel Uriel , Aguilar-West Abelardo Alexanders , Montiel-Moreno María Dolores
Published: December 2023

Dieulafoy's lesion is defined as a dilated submucosal artery that can cause spontaneous rupture and massive gastrointestinal bleeding. It is usually an incidental finding and is identified as a prominent linear or serpentine artery.

We report the case of a 47-year-old patient who presented with a Dieulafoy's lesion located in the gastric fundus, which was repeatedly treated with clipping and endoscopic sclerosis, without resolving. She presented to the interventional radiology service for endovascular treatment, which after performing angiography confirmed active bleeding at the level of the left gastric artery and proceeded to embolize with 2 coils. This is a case where endovascular treatment proves to be an effective and decisive option for the treatment of bleeding in this type of injury.
Death by Tchaikovsky
Authors: Motazedian Táhirih
Published: December 2023

The 2010 film Black Swan embeds Tchaikovsky’s Swan Lake ballet within a macabre meta-ballet, in which the “Black Swan” character subsumes the life of Nina, the prima ballerina tasked with playing the dual role of Odile/Odette. Nina fulfills the balletic role by succumbing to a nightmarish nineteenth-century “death and the maiden” narrative in which she attains “perfection” by disappearing into the ballet and ultimately dying. The weaving-together of threads of musical analysis, nineteenth-century music pathology, and twenty-first-century psychology reveals a darkly whimsical reading of the narrative in which Tchaikovsky himself is drawn into the filmic fray as the phantasmagorical force behind Nina’s psychological derailment.
Creative Writing and Translation
Authors: Hart Jonathan-Locke
Published: December 2023

Creative writing and translation have an intricate relation in writing, scholarship, the classroom and beyond. The philosophical context of mimesis and anti-mimesis affects writers, translators, critics, scholars, teachers and students. Imitation, innovation, originality, copying all become part of the debate over translation and creativity. From Plato through Roger Ascham to Immanuel Kant and beyond, this article explores the relation between writing and translation and discusses contributions to this debate East and West before proceeding to the author’s experience in those two realms, especially in Canada, England, China and the United States. I argue that translation is creative, for both creative writing and translation are – along with reading – forms of interpretation. Translators of poetry are, or should be, poets who create anew or recreate the poems.
NICKEL-BASED SUPERALLOYS EXPLOITATIONAL PROPERTIES RISING DUE TO THE INFLUENCE ON LATTICE PARAMETERS
Authors: Hlotka O. , Ol'shanetskii V. , Kononov V.
Published: December 2023

Objective. It consists in establishing relationships between the chemical composition, mechanical properties, and dimensional inconsistency of crystal lattices of nickel-based superalloys. That makes it possible to reduce the volume of experimental research in the conditions of the production process and experimental developments.
Research methods. The results of experimental and calculated data, formed on the basis of experimental and results taken from open sources, are given. The phase composition was determined by X-ray structural analysis using the Bragg-Brentano focusing method on a RIGAKU MINIFLEX 600 diffractometer (CoKα radiation). The experimental values were processed by the method of least squares with obtaining correlation dependencies of the “parameter-property” type and establishing mathematical equations of regression models that optimally describe these dependencies.
Obtained results. It was established that with an increase in the amount of misalignment of crystal lattices, the strength of alloys decreases due to significant internal stresses. It was found that for alloys of uniform and directional crystallization, the extremum is observed at a value of 1.5...1.6 Kγ′, this is due to a decrease in the number of elements in the γ-solid solution. It is shown that the obtained dependences correspond to reality and coincide with experimental data at the level of 10 %.
Scientific novelty. The value of the work lies in the fact that the dependence of the influence of alloying elements on the mechanical properties and the discrepancy in the sizes of the crystal lattices was obtained, which made it possible to determine the properties without conducting experiments. It was established that changes in the course of dependencies are closely correlated with the processes taking place in the structure of alloys.
Practical value. The obtained dependencies can be used both for the development of new superalloys and for the improvement of the compositions of industrial alloys.
RESEARCH OF THE CHANGE IN THE CONSOLIDATED MASS IN FLAT MULTI-LINK MECHANISMS
Authors: Оmelchenkо О. , Аkimov I. , Shtanko P. , Shaleva N.
Published: December 2023

Purpose. Determination of the equation of motion of the crank-connecting mechanism using the methods of researching the motion of flat multi-link mechanisms. Development of the dependence using the theorem on the change in kinetic energy of the mechanical system for determining the total mass of flat mechanisms when the angle of rotation of the driving link of the flat mechanism changes.
Research methods. Dynamic analysis of the mechanism. The method of reducing forces and masses. Mathematical determination of the kinetic energy depending on the angle of rotation of the crank of a flat mechanism. Regression processing of the obtained calculation results and their subsequent correlation analysis were carried out using computer software for the analysis and visualisation of scientific and statistical data – «SigmaPlot» from the company «Jandel Corporation».
Results. A calculated formula for the change in the combined mass depending on the angle of rotation of the crank was obtained. The existence of a sinusoidal relationship between the calculated parameters (crank angle and reduced mass) was established. The correlation analysis of the obtained function showed a sufficiently high degree of relationship between the calculated data and the mathematical dependence, while the correlation coefficient was r = 0.972. The graph of the determined mathematical dependence also showed a fairly high correlation between the specified parameters. The resulting equation can be used for systems with one degree of freedom. For mechanisms with several degrees of freedom, the law of change of the combined mass will be different for each degree of freedom.
Scientific novelty. Using the calculated formulas of kinetic energy for planar mechanisms, the law of change of the reduced mass in planar mechanisms, which takes into account the rotation of the crank around its own axis, is obtained.
Practical value. When designing flat crank mechanisms, it is necessary to take into account the effect of inertial forces, the value of which depends on the mass and acceleration. This makes it possible to calculate correctly the dynamic loads on the parts of the flat mechanism (bearings, etc.). The obtained mathematical dependence of the change in the combined mass on the angle of rotation of the leading link of the mechanism makes it possible to analyse the change in the combined moment of inertia, which in turn affects the change in torque.
INFLUENCE OF FUSED DEPOSITION MODELING REGIME PARAMETERS ON MANUFACTURING TIME OF UAV PARTS
Authors: Tumarchenko L. , Vyshnepolskyi Y.
Published: December 2023

Purpose. Investigate the regularities of FDM process parameters influence on the manufacturing time of parts.
Research methods. The samples for research were produced by the FDM method on a Profi+midi 3D printer. Slic3rPE software were used for CAD model slicing and G-code preparation. The samples were printed using ABS+ filament. The STATISTICA software package was used for statistical processing of the results.
Results. The influence of different combinations of FDM process parameters (printing speed, layer height, infill geometry, infill density) on the manufacturing time of products was examined. The main factors affecting the manufacturing time were established: printing speed, layer height, infill density and the interaction of these factors
Scientific novelty. Analysis of the manufacturing time dependence on the layer height and the infill density showed that when selecting a layer height of 0.15 mm and 25 % infill and a layer height of 0.3 mm and 100% infill, the manufacturing time turned out to be nearly identical. It can be concluded that for a lower layer height, increasing the infill density significantly increased the manufacturing time, while setting a higher layer and increasing the infill density led to a small increase in the manufacturing time. It was found that for a layer height of 0.15 mm at a printing speed of 40 mm/s, the manufacturing time significantly increased compared to a printing speed of 80 mm/s, while when selecting a layer height of 0.3 mm, the manufacturing time is less and a decrease in the printing speed led to a small increase of manufacturing time compared to a layer height of 0.15 mm. It was established that an increase in printing speed led to a decrease in manufacturing time and an increase in infill density led to an increase in manufacturing time. Thus, the manufacturing time at a printing speed of 40 mm/s and infill density of 25 % differed slightly from a printing speed of 80 mm/s and infill density of 100 %.
Practical value. A regression equation was obtained which allowed predicting the influence of the FDM process parameters on the manufacturing time of parts.
CORRECTION OF THE CYLINDRICAL HELICAL-GEAR WHEEL PAIR FOR WEAR DECREASE OF TEETH’ INVOLUTE SURFACES
Authors: Popovych O. , Shevchenko V.
Published: December 2023

Purpose. It is to create a method for determination of profile shift coefficients, such that during the operation of a cylindrical helical-gear pair the sum of the wear rates of involute surfaces on the contacting sections at the highest and lowest active points of teeth’ profiles of driving and driven wheels will be a minimum.
Research methods are based on integrated application of the involute gear theory and tribological laws. The secant method that is known in computational mathematics is used to find a root of nonlinear equation.
Results. The method is created for determination of rational values of correction parameters for cylindrical helical-gear wheels, which maximize the service life of this gear pair until the maximum sum of worn-layer thicknesses on the contacting sections of the teeth’ active surfaces reaches limiting permissible value. An example of application of this method in design calculation of the cylindrical helical-gear pair is given.
Scientific novelty. Calculation model is elaborated for determination of the sum of worn-layer thicknesses on the most wearing contacting sections of the teeth’ active surfaces of a cylindrical helical-gear wheel pair. It is derived an equation of the linkage between such values of profile shift coefficients for the driving and driven helical-gear wheels which minimize the greatest sum of wear rates on mentioned sections of teeth’ surfaces. Solution of this equation by numerical method for the helical-gear pair having standard distance between axes allows determination of rational values of correction parameters for these wheels.
Practical value. Application of the created method for determination of profile shift coefficients is expedient in design of cylindrical helical-gear pairs for machines and equipment, which operate in conditions when it is impossible to protect the engagement region from ingress of abrasive particles.
DETERMINATION OF THE STRESSED METAL STATE DURING HOT ROLLING BY THE FINITE ELEMENT METHOD
Authors: Ivanov I. , Matіukhin A. , Ben A. , Kryvykh Yu. , Kulabnieva O.
Published: December 2023

Purpose. Determination of the stress-strain state of the metal during the rolling of large ingots to prevent the occurrence of internal defects, and determining the effect of forced cooling of the ingot surface during hot rolling on the stress-strain state.
Research methods. Finite element method, upper estimate method.
Results. Based on the finite element method, a comparative simulation of the stress-strain state of the ingot with different cooling times was performed. As a result of the study, it was established that the forced cooling of the ingot surface during hot rolling helps to reduce the probability of the internal continuity defect forming. The given results of comparison of the distribution of strain intensity along the rolling cross-section in the basic version and with additional annealing indicate a decrease in the probability of formation of discontinuities in the axial zone of the ingot. This, in turn, proves the effectiveness of forced annealing of the surface layers of the ingot (workpiece).
Scientific novelty. A mathematical model of the distribution of the main stress state components was developed. It took into account the redistribution of temperatures and, as a result, the mechanical properties of the metal according to the height of the deformation focus during the hot rolling of relatively large blanks.
Practical value. The use of forced cooling leads to a significant increase in hydrostatic and normal stresses in the axial zone, reducing the probability of the formation and subsequent growth of internal continuity defects. Thus, the quality of finished products increases, in particular, valuable rolled products made of special grades of steel.

Published: December 2023

This study is dedicated to the examination of cavitation-induced erosion, a critical factor in optimizing the efficiency of hydraulic systems, including hydropower plants and pumping systems. To accomplish this, we conducted a sensitivity analysis utilizing a cavitation jet apparatus (CJA) and an experimental configuration that featured a vertical cylindrical test tank, a submerged nozzle, and an aluminum sample (specifically, alloy 6351 T6). The study maintained a consistent standoff distance of 5 cm and an orifice diameter of 2 × 10-3 m. Two distinct nozzle geometries were tested to assess their influence on cavitation erosion. The outcomes revealed that the 20° conical sharped-edges nozzle resulted in the highest erosion rates, while the commercial nozzle (MEG 2510) caused comparatively less erosion. By standardizing the test duration to 1200 seconds and using a cavitation index of 0.14, the researchers avoided overlapping pits. In summary, the CJA, with these adjustments, demonstrated its effectiveness as a tool for evaluating the resistance of solid surfaces to cavitation.
Teaching Turkish-Islamic Scholars in Mobile Augmented Reality Environment: Its Effect on Students' Scientific Attitudes
Authors: YILDIRIM Pelin , KEÇECİ Gonca
Published: December 2023

Science history showcases scientific thought's evolution and discoveries to students. Some topics include abstract concepts, making them challenging. Technology enhances teaching history of science, making it more effective and accessible. This study aims to examine the influence of teaching the lives of Turkish-Islamic scholars who have made significant contributions in various scientific disciplines such as astronomy, chemistry, and physics through TISAR-3D, a Mobile Augmented Reality (MAR) based learning environment, on secondary school students' scientific attitudes. A quasi-experimental method was employed in this study. This study was conducted in a public school in Elazığ, involving a total of 90 students in the 7th grade. Half of these students were assigned to the experimental group, while the other half formed the control group. The study was carried out for a duration of eight weeks on the experimental and control groups. The study lasted for eight weeks and consisted of an experiment group and a control group. The TISAR-3D application was used in the experiment group, while reading texts were used in the control group. The data obtained through the Scientific Attitude Scale were analyzed quantitatively using the SPSS 22 software package, and ANCOVA was applied. The study found that although the average scientific attitude scores of students in the experiment group, where the MAR application was used, were higher than the average scores of students in the control group, where reading texts were used, there was no statistically significant difference. Although primary textbooks are accessible to all students, insufficient coverage of Turkish-Islamic scholars and unfamiliarity with practical scholars may explain the lack of significant differences in scientific attitudes. Also, an eight-week study may not sufficiently alter students' scientific attitudes. By designing longer-term studies, a better understanding of how scientific attitudes develop and change over time can be achieved.
Experimental study on compressive strength of in situ concrete tested with arc pressure method
Authors: Yang Suhang , Hu Chen , Xu Zhifeng
Published: December 2023

The innovative arc pressure testing method (APTM) is adopted in this study to obtain the strength of in situ concrete and reduce damage to the concrete structure. This method is related to the double shear plane of the concrete core. A specific APTM apparatus is used to apply loads in order to obtain the approximate pure shear stress and shear strength of the concrete core. Factors affecting the strength of concrete, such as aggregate type and concrete moisture, were found not to have an impact of the applicability of APTM. The compressive strength range of the tested cube concrete samples is 20–60 MPa. The reliability and repeatability of APTM are superior to in situ testing techniques such as Schmidt hammer (SRH) and pull-off testing methods. The experimental results indicate that APTM is suitable for in situ testing of concrete compressive strength of prefabricated buildings and beam–column joints in dense steel structures. Compared with other testing methods, its accuracy is much higher and the damage to the structure is minimised.

Authors:   National Research  Council of Italy, Francesco Contini
Published: December 2023

E-justice platforms are becoming the new working environment of judicial institutions. Their development is challenging, with failures and incomplete deployments. At the same time, their implications go beyond the functional level and entail legal, governance and even constitutional dimensions. The paper analyses the two e-justice platforms used to handle civil and criminal proceedings in Italy. Trial OnLine (TOL) is the fully deployed e-justice platform for civil proceedings, while Criminal proceedings online is similar but much less developed. Tracking the two case histories and analysing similarities and differences allows to identify common challenges and functional and institutional implications. This paper was presented at the International Scientific and Practical Conference “E-justice: Challenges and Opportunities in the Digital Era” (September 26-27, 2022, v. Sary -Oi, Issyk-Kul region, Kyrgyzstan) and published with support of Volkswagen Foundation (Germany).
