Authors: Alarcón Hernández Paola , Venegas Carrasco Carolina , Vásquez Bustos Víctor
Published: May 2024

El objetivo de este estudio es comprender las representaciones discursivas sobre el matrimonio igualitario y las personas LGBTIQ+ en comentarios a 11 noticias publicadas por medios de comunicación chilenos en sus páginas de Facebook, entre 2019 y 2021. La investigación, inscrita en el paradigma interpretativo, es de alcance descriptivo y exploratorio. Se utiliza una metodología cualitativa y las estrategias de la Teoría Fundamentada Empíricamente (Strauss y Corbin, 2002). En este trabajo postulamos que mediante estrategias discursivas las personas manifiestan actitudes, las cuales, a su vez, son un componente fundamental de las representaciones sociales (Moscovici, 1979). Siguiendo a Wodak (2003), se analizaron estrategias de nominación y predicación para configurar discursivamente a las personas LGBTIQ+ y se identificaron los topoi que avalan el rechazo al matrimonio igualitario. Mediante la codificación axial se identificaron como categorías centrales y relacionadas: el matrimonio es entre un hombre y una mujer y las personas LGBTIQ+ son inmorales.

This paper presents numerical and experimental studies focused on the optimisation of laser welding parameters for AISI 316L stainless steel. The focus of the numerical studies was to obtain the mathematical model with the least time complexity and the highest fidelity. Based on the comparison of different mathematical models, a combination of two models, double ellipsoidal and conical models, was found to be optimal for the numerical simulation of the laser welding process. The studies were also complemented by material characterization studies for validation purpose. A pulse duration of 8 milliseconds and a current of 400 amperes with an average power of 380W were found to be the optimum parameters for laser welding of standard gauge 12 sheet of stainless steel AISI 316L. In addition, the effect of duty factor of the pulsed laser beam on the weld profile was also investigated and was found to be a major contributor to the optimisation process. The properties of the sample welded with the optimised set of parameters were also compared with the base metal, and based on the mechanical characterisation studies, it was found that the yield strength and hardness of the welded sample were improved, but the overall ductility was slightly reduced as compared to the base metal. The average weld zone size was also reduced by increasing the power density due to multiple reflections of the beam.

Adolescents meet a variety of difficulties on their way. Facing the challenges of the adult world, followed by hormonal, and sexual body restructuring teenagers have to win this battle, in another way, they will be destroyed by different types of effects. Adolescence is a secondary individuation when a child has to finally reject parents as objects of attachment, as authority figures find new authority figures and new objects of attraction outside the parental family. Parents, teachers and peers play an important role in adolescents growing up. Studying is one of the main tasks of adolescents. Depending on the individual peculiarities of teenagers they can try to avoid it or satisfy educational needs. The purpose of the work is to determine the peculiarities of children’s development during adolescence and define their influence on the process of education. The work was based on scientific articles of the last decade. In the search process the terms: "adolescence/psychoanalysis", "adolescence / psychoanalytic pedagogy", "adolescence / educational problems", "adolescence / emotional problems", "adolescence/education", or "adolescence/parents", or "adolescence/peers" were used. It was settled that the educational activity of adolescents has its difficulties and contradictions, but there are also advantages that a teacher can and should rely on.

Published: May 2024

Global political instability has profound physical and psychological effects on the world's population, particularly evident in Ukraine due to a brutal war resulting in genocide, widespread destruction of ordinary life, and severed familial ties. The psychological impact extends to both combatants and civilians, regardless of their location. Military operations' emergencies disrupt daily lives, undermining fundamental needs for security and a coherent worldview. While the human psyche can adapt to crises, emotional strain may lead to resilience or breakdown, impacting essential functions. Psychological rehabilitation is crucial in the broader rehabilitation spectrum, encompassing social aspects. This article delineates the position and significance of psychosocial rehabilitation within the context of broader rehabilitation for those dealing with disabilities, posttraumatic stress disorder, and the aftermath of war, captivity, and torture. It also seeks to identify promising avenues for social rehabilitation in the current landscape. In a comprehensive search, relevant studies were examined in the DOAJ and EBSCOhost databases over the last decade.

Published: May 2024

Currently, the education of children with special educational needs is attracting more and more attention and special efforts from both governmental and non-governmental institutions and agencies. The society’s attitude to the general education of children with special educational needs generally reflects the level of the state’s development. Inclusive education implies a specific approach to the learning process that creates educational opportunities for all children, especially those with special educational needs. The purpose of the academic paper is to identify the major strategies of inclusive education for their subsequent implementation in practice in the modern context. In order to achieve the goal outlined, we conducted a search for relevant studies in the DOAJ and EBSCOhost databases over the past ten years. According to the literature, creating inclusive classes requires the professional experience of teachers, who must be friendly and understanding leaders in the class. Inclusive education promotes equal opportunities through respect for diversity. Inclusive education is based on the belief that all children are equal members of local school communities, the exclusion of any discrimination against children with special educational needs and the creation of appropriate conditions for quality, full-fledged education, training and development. Effective inclusive education depends on a variety of factors, and it is not just the inclusion of children with special educational needs into the general education school community. It requires high-quality, experienced teachers with a “great” heart, support and adequate attitude of parents, and comprehensive support on the part of state institutions. The compilation of special educational programs, and assessment systems, the development of effective strategies against the background of using modern methods, including information technologies, and the mandatory availability of highly qualified teachers who can organize and motivate students are necessary factors for the successful implementation of measures on inclusive education.

The practice of digitizing project-technological and design activities in training future vocational education and technology teachers has gained popularity in recent years. The active transition of all societal processes (communication, professional activities, leisure, etc.) into the digital space has led to an increase in interaction speed within society. Higher education institutions are incorporating this practice into the student learning experience to keep pace with the times. This enables them to prepare graduates who actively employ innovative methods in their professional work. In response to the challenges of the time, higher education institutions are introducing elements of innovation into the training process of future vocational education and technology teachers, thereby creating new principles and teaching methods. The focus of our interest is the exploration of these working principles, the analysis of practices, and the characterization of methods for digitizing project-technological and design activities. Describing the commonalities and differences in approaches to teaching this field defines the subject of our theoretical research. The article aims to provide a retrospective analysis of project-technological and design activities in the process of training future teachers of vocational education and modern technologies in Ukraine and worldwide. Research methodology involves the use of systemic-structural, comparative methods of analysis, information synthesis, and the inductive method of the research.
REUSE OF SPUN PILE PRODUCTION WASTE FOR PAVING BLOCK DEVELOPMENT BY TAGUCHI METHOD
Authors: Wajdi Farid , Herkuntarto Fajar , Ramayanti Gina
Published: May 2024

The production of precast spun piles generates solid and liquid waste products. The solid waste consists of stone, sand, and mud materials, while the liquid waste consists of K-600 grade concrete cement mixed with water. It is poured into a 1m3 container and solidifies within 3 hours. The production process of precast concrete piles is fast, which results in quick waste accumulation in the factory area. This research aims to transform the waste into paving blocks suitable for road construction. The Taguchi method is employed to determine the optimal strength of the paving blocks using three variables: (1) the ratio of solid to liquid waste in three levels - 70:30%, 60:40%, and 50:50%, (2) mixing time in three levels - 5, 10, and 15 minutes, and (3) curing time in three levels - 3, 7, and 14 days. The strength of the paving blocks is tested by measuring the maximum compressive strength. The results indicated that the best combination for achieving maximum compressive strength was using (1) a 50%:50% ratio of solid to liquid waste, (2) a curing time of 14 days, and (3) a mixing time of 5 minutes, resulting in a maximum compressive strength of 125.72 Kg/cm2. It is equivalent to Grade D paving blocks that are suitable for road application.

Authors: Widiatmoko Julian Anindito , Purwaningsing Ratna , Susanty Aries
Published: May 2024

Saat ini teknologi 3D Printing sedang sangat berkembang dengan biaya yang semakin terjangkau. Hal ini mendorong bermunculannya jasa cetak 3D di beberapa kota di Indonesia. Model bisnis yang digunakan adalah menerima model 3D dari pelanggan kemudian mencetaknya dengan 3D printer. Disebabkan oleh tidak terbatasnya variasi model 3D yang mungkin diterima, jasa 3D printing perlu menetapkan basis tarif  dasar yang dipakai. Terdapat dua pilihan basis tarif dasar yang merepresentasikan biaya langsung, yaitu basis material dan basis waktu cetak. Studi ini mengevaluasi performansi kedua basis tersebut menggunakan simulasi Anylogic dalam memaksimalkan pendapatan. Seratus model 3D digunakan untuk mengakomodir variasi pesanan. Estimasi jumlah material dan waktu cetak untuk masing-masing model didapat dari software slicer dan digunakan sebagai inputan simulasi. Dari hasil simulasi pada rentang waktu operasi satu tahun, didapatkan kesimpulan bahwa meskipun kedua basis tarif dasar menunjukkan keunggulan biaya langsung secara bergantian untuk model 3D yang  berbeda, basis material dapat memberikan jumlah pendapatan total yang lebih besar. Rate basis evaluation of 3D printing service using Anylogic simulation. Nowadays, 3D printing technology has been vastly developed at an even more affordable cost. This fact encourages the growth of 3D print services in some Indonesian cities. The business model for this type of service is simple: receiving a 3D model from the customer and then realizing it using 3D printing. Since there are unlimited variations of 3D models that come in, 3D services providers need to determine their basic rate. Two options of rate basis represent direct cost of 3D printing operation, those are material basis and printing time basis. This article evaluates the performance of the two using Anylogic simulation in maximizing revenue. A hundred 3D models were utilized to accommodate variation in order. Material needs and printing time estimation of each model were determined using slicer software as input for the simulation. The result of one year simulation time shows that although both bases can give superiority on direct cost for different individual 3D models, the material basis rate was able to present greater operational income.Keywords: 3D printing; rate basis; Anylogic; simulation
Religijna materialność świata w powieści Grace McCleen „Świat Judyty” ” [„The Land of Decoration”]
Authors: Kowalcze Małgorzata
Published: May 2024

The article discusses the novel The Land of Decoration by Grace McCleen’s applying elements of selected posthumanist theories, mainly object-oriented ontology (G. Harman, T. Morton) and new materialism (J. Bennett). It considers the assumption that in the novel, the ontological status of human beings as well as material objects is fluid, as both play the role of a prop and the entity manipulating the prop. The author focuses on the main character’s religious cognitive perspective and her relations with her (im)material surroundings. An attempt is made to point out certain similarities between the religious worldview and the posthumanist approach. To this end, the author discusses several issues related to the dualistic categories of material vs. immaterial, rational vs. irrational, as well as human vs. non-human.

Authors: Yang Min , Hu Chao , Huang Jun , Fu Ying , Zhang Qi , Cheng Yulan , Lu Jie , Li Guiling , Zhang Jun
Published: May 2024

Objectives

Anti-mitochondrial antibody (AMA) is not always present in patients with primary biliary cholangitis (PBC). We aimed to determine the additional value of anti-hexokinase 1 (anti-HK1) and anti-kelch-like 12 (anti-KLHL12) antibody in PBC and analyzed the biochemical and immunological parameters of 212 subjects, including PBC patients and healthy controls.

Methods

Serum anti-gp210 and sp100 antibodies were determined by an immunoblotting test (IBT). Enzyme-linked immunosorbent assay (ELISA) was employed to evaluate anti-HK1 and anti-KLHL12. The diagnostic value of anti-HK1 and anti-KLHL12 to PBC was analyzed by constructing a receiver operating characteristic (ROC) curve.

Results

ROC analyses didn’t show a very good performance of serum anti-HK1 for PBC diagnosis; the AUC was 0.664 with a sensitivity of 53.3 % and a specificity of 79.2 %. Regarding anti-KLHL12, ROC analysis yielded an AUC of 0.626, with a sensitivity of 45.7 % and a specificity of 93.8 %. For AMA-negative PBC patients, the AUC increased to 0.790 for KLHL12, and 0.708 for HK1. AMA combined with anti-HK1 or anti-KLHL12 antibody significantly improved the diagnostic sensitivity of PBC from 82 to about 95 %, respectively. In AMA-negative PBC patients, the sensitivities for anti-HK1 (62.50 %) and anti-KLHL12 (75 %) antibodies were higher than for anti-gp210 (37.5 %) and anti-sp100 antibody (43.75 %). When these four antibodies were combined, the overall sensitivity increased to 87.5 %.

Conclusions

The determination of anti-HK1 and anti-KLHL12 facilitates the diagnosis of PBC, particularly in AMA-negative patients. Adding anti-HK1 and anti-KLHL12 antibodies to clinical detection enables early diagnosis and timely treatment, potentially improving patient prognosis.
“Let’s ride this out together”: unpacking multilingual top-down and bottom-up pandemic communication evidenced in Singapore’s coronavirus-related linguistic and semiotic landscape
Authors: Gu Chonglong
Published: May 2024

Access to languages is a human right and multilingual crisis communication is vital during a pandemic. Multilingual and (super)diverse Singapore features four official languages (English, Chinese, Malay, and Tamil), with English being a dominant lingua franca. Additionally, other minority/migrant languages are also spoken to varying degrees (e.g. Tagalog, Thai, Burmese, Hindi, Punjabi, and Nepali). Contributing to public health communication research, this study explores Singapore’s multilingual pandemic communication practices evidenced on its COVID-related linguistic landscape, drawing on real-world top-down and bottom-up signs (N = 128). Top-down signs in Singapore are found to mostly feature English monolingualism or the four official languages. In comparison, Singapore’s bottom-up COVID-scape manifests in more scenarios. The findings are aligned with Singapore’s linguistic policy and existing pre-COVID linguistic ecology. What is conspicuously absent is that minority/migrant languages other than the four official languages are rarely represented. Despite Singapore's relative success in the anti-Covid journey overall, this raises questions of inclusiveness and accessibility and suggests that the city state needs to get out of its linguistic “comfort zone” and use a broader range of languages in crisis communication, especially considering the possibility of disease X and other future public health contingencies. The wider significance and ramifications of the study are also explored and discussed.
Fatigue life evaluation of laser welded lap joints of dissimilar aluminum alloys
Authors: Liao Xiangyun , Wang Ruijie , Zhao Pinglin
Published: May 2024

Constant amplitude fatigue tests were conducted on 6061/7075 dissimilar aluminum alloy laser welded lap specimens, as well as weld line cross-section hardness measurements. The fatigue test results show that the specimens exhibit multiple fracture modes that exit near the weld seam. The microhardness data on weld line cross-section from 7075 side to 6061 side display a sharp change and the softening phenomenon is serious. The hardness variation in heat affected zone of laser welding is very shallow, and its hardness is close to that of the base material. It was found that there are slag inclusions and pores in the weld seam when observing the fatigue fracture surface using SEM, and a small amount of secondary cracks were generated. However, stress concentration plays a dominant role in causing specimen fracture under fatigue loading, rather than welding defects. Defective specimens are found to have higher fatigue strength. The fatigue life prediction results obtained by the notch stress method and the hot spot stress method are both conservative and fall within two factor lines. The hot spot stress method has relatively higher accuracy for life prediction. The accuracy of both methods in predicting life is influenced by the location of the fracture.

Authors: Henriksson Gunnar , Germgård Ulf , Lindström Mikael E.
Published: May 2024

Kraft pulping of wood is based on efficient depolymerization and solubilization of lignin, while cellulose is relatively undamaged. Non-cellulose cell wall polysaccharides are however in some cases heavily degraded, especially pectin and to a lesser degree also glucomannan while, xylan is relatively stable. In this mini-review, the most important reactions in lignin and polysaccharide degradation in kraft pulping are described, both the technically favorable and the problematic reactions, and the chemical background to discuss the advantages and drawbacks of the process. An attempt to put the different reactions in the perspective of the goals of the pulping process is made and a special focus is on the development of color in the pulp fiber during the kraft pulping.
Phytoremediation of radium contaminated soils: recent advances and prospects
Authors: Wang Jianlong , Chen Can
Published: May 2024

Radioactive radium (Ra) mainly comes from the mining and milling of uranium and other metal or non-metal mines, phosphate production and fertilizer use, production of oil and gas, coal combustion, wastewater treatment, and various wastes from the above activities, which is ubiquitous in the environment. Phytoremediation is a green and cheap remediation technology for metal/radionuclide-contaminated sites. Radium is often of particular interest and there are many literatures on parameters of Ra concentration in plants and transfer factors from soil to plant from a radiological impact assessment point of view. However, review articles on phytoremediation of Ra-polluted soil are relatively few. This review focused on radium-polluted soil phytoremediation, involving two main strategies of phytoextraction and phytostabilization, which covered the potential (hyper)accumulators for Ra, characteristics of Ra uptake from soil by plants, influencing factors, and phytostabilization application. In future research works, more attention should be paid to the deep insights and mechanism researches of Ra uptake/immobilization by plants. This review will deepen the understanding of the relationship of radium-soil-plants, and to enhance the potential application of phytoremediation as an alternative treatment technology for remediation of Ra-polluted soil site.

Published: May 2024

In this study, Kozo fibres were fibrillated using the stone wet milling method and the wet atomisation method both deriving from nanocellulose production processes. Kozo fibres with a high degree of external fibrillation were obtained by using the stone mill wet grinding method. Although fibres exhibited the same structure as untreated Kozo fibres, their bonding properties improved. Applying the wet atomisation method, fibrillated Kozo fibres with different degrees of fibrillation were obtained depending on the number of treatments. Fibrillated Kozo fibres can be used in conservation as an adhesive for lining and other stabilisation treatments and may in certain cases replace starch paste, which is susceptible to microbiological damage. Only Kozo fibres and water were used in both mechanical fibrillation methods; therefore, the resulting material can be considered a safe alternative to more traditional adhesives.
BiVO4-based heterojunction nanophotocatalysts for water splitting and organic pollutant degradation: a comprehensive review of photocatalytic innovation
Authors: Patial Baneesh , Bansal Ajay , Gupta Renu , Mittal Susheel K.
Published: May 2024

The novel semiconductor photocatalytic material bismuth vanadate (BiVO4) is gaining significant attention in research due to its unique characteristics, which include a low band gap, good responsiveness to visible light, and non-toxic nature. However, intrinsic constraints such as poor photogenerated charge transfer, slow water oxidation kinetics, and fast electron–hole pair recombination limit the photocatalytic activity of BiVO4. Building heterojunctions has shown to be an effective strategy for enhancing charge separation and impeding electron–hole pair recombination over the last few decades. This review covers the state-of-the-art developments in heterojunction nanomaterials based on BiVO4 for photocatalysis. It explores heterojunction design, clarifies reaction mechanisms, and highlights the current developments in applications including photocatalytic water splitting and organic matter degradation. Finally, it offers a preview of the development paths and opportunities for BiVO4-based heterojunction nanomaterials in the future. This comprehensive assessment of BiVO4-based heterojunctions provides insightful knowledge to researchers in materials science, chemistry, and environmental engineering that will drive advances and breakthroughs in these important fields.
Functional alterations in overweight/obesity: focusing on the reward and executive control network
Authors: Guo Haoyu , Han Jinfeng , Xiao Mingyue , Chen Hong
Published: May 2024

Overweight (OW) and obesity (OB) have become prevalent issues in the global public health arena. Serving as a prominent risk factor for various chronic diseases, overweight/obesity not only poses serious threats to people’s physical and mental health but also imposes significant medical and economic burdens on society as a whole. In recent years, there has been a growing focus on basic scientific research dedicated to seeking the neural evidence underlying overweight/obesity, aiming to elucidate its causes and effects by revealing functional alterations in brain networks. Among them, dysfunction in the reward network (RN) and executive control network (ECN) during both resting state and task conditions is considered pivotal in neuroscience research on overweight/obesity. Their aberrations contribute to explaining why persons with overweight/obesity exhibit heightened sensitivity to food rewards and eating disinhibition. This review centers on the reward and executive control network by analyzing and organizing the resting-state and task-based fMRI studies of functional brain network alterations in overweight/obesity. Building upon this foundation, the authors further summarize a reward-inhibition dual-system model, with a view to establishing a theoretical framework for future exploration in this field.
Promoting students as partners in a pilot study involving undergraduate students and instructors in Spanish as a foreign language courses
Authors: García-Allén Ana , Heru Sari , Martínez Richard
Published: May 2024

Through the student-as-partners (SaP) framework, this paper explores how this can enhance undergraduate Spanish as a foreign language flipped classroom courses and promote student engagement and satisfaction. Traditionally, higher education courses are designed and developed by faculty members; however, our pilot project proposed collaboration between students and instructors in the design and implementation of course activities. This paper explores the model’s effects and outcomes through four surveys administered at the end of the academic year. Each survey included key factors related to the learning experience: student enjoyment, emotional support, relatedness to peers, feedback from/for students, and content-related support. Collectively, these perspectives were used to reflect on the feedback provided, which helped us achieve our objective: the creation of teaching and learning resources to engage future cohorts and increase student retention. Although this model is presented in the foreign language context, it is transferable to any discipline.

Authors: Lesnick Alice , Evans Sabea K. , Schall Margo , Cook-Sather Alison
Published: May 2024

Although assessment of student learning remains a thorny area for co-creation in education, a growing number of researchers and practitioners advocate and enact partnership in formative and summative assessment as part of equity work. In this case study, we join these efforts in reflecting on students’ and our own experiences of the midterm conversation that we use as a key formative assessment structure and process across three co-facilitated courses. The midterm conversation—a partnership among students and instructors as co-teachers—is embedded in course design and curriculum with the goal of advancing, informing, and sustaining our pedagogical commitments. This case illustrates how we practice assessment as dialogue and as emergent understanding. This practice is based on an expectation of diverse learning goals and outcomes and on trust in students’ capacities to direct their learning with reference to their own interests and standards for their work.

Published: May 2024

My journey of student-faculty partnership is one that I did not anticipate joining when I signed up for the International Students Overcoming War (ISOW) Scholarship Initiative. ISOW is part student-club, part humanitarian organization that provides students the opportunities to hone their leadership skills as they administer the operations of the scholarship program. The partnerships between students, staff, and Faculty create (experiential) learning for all that enhances personal and professional development in this community. Over the course of four years, with progressive leadership responsibilities ranging from Secretary to a full-time contract position, I have been able to experience partnership from the student and staff perspective. In this essay I share the key lessons I have learned about partnership as I moved through these roles and experienced the challenges of self-reflection, holding multiple identities, and moving on.

Whole-body electromyostimulation training (WB-EMS) has gained increasing popularity as a training method in recent years. This brief review aims to summarize the potential benefits and risks of WB-EMS in many different populations and purposes. The findings of this review suggest that WB-EMS is particularly effective for improving muscle mass and strength outcomes in untrained people. However, more high-quality studies are needed to determine its long-term effects and to optimize its use in different populations and training contexts. For general health-related parameters, WB-EMS may be a feasible and time-efficient exercise strategy combined with proper energy or protein intake throughout longer periods.

In order to synthesize CuO, SnO2, and Sn doped CuO nanocomposites, accessible and non-toxic materials, specifically leaf extract from Centratherum punctatum, were used in this work to apply the concepts and practices of green chemistry. These methods are both economical and environmentally friendly. A comprehensive range of characterisation techniques, including as FTIR, X-ray diffraction, and UV-vis spectroscopy, were also used to confirm the structures of all the produced nanomaterials. Instead, FESEM and EDAX were used to analyze the morphologies and elemental composition of recently produced nanomaterials. A decline in the optical band gap values was indicated by the red shift observed in the UV-vis study following tin doping. A sample's presence of different functional groups is confirmed by FT-IR analysis. For CuO NPs, SnO2, and Sn doped CuO NCs, the XRD results yielded crystallite sizes of 6 nm, 21 nm, and 29 nm, respectively, for the produced particles. The ferromagnetic, diamagnetic, and super paramagnetic characteristics of the produced samples at room temperature were validated by vibrating sample magnetometer experiments. Cyclic voltammetry is used to examine the nanoparticles' electrochemical analysis. Using Sn doped CuO nanocomposite material, it shows a high specific capacitance value of about ~187 Fg-1 at a current density of 10 mV/s. It was found from the electrochemical studies that the produced nanomaterials are suitable for capacitive behaviour. After all, the presence of inhibition zones surrounding each well led us to the conclusion that the nanoparticles exhibited antibacterial activity against the pathogenic strains of Staphylococcus aureus and Escherichia coli.

Notas sobre el neoliberalismo y el socialismo del siglo XXI en América Latina (1980-2015)
Authors: Barrera-Rivera Dan Abner
Published: May 2024

Neoliberalism is an economic model that seeks to reshape society with the market at its core. It first emerged in 1973 in Chile and later spread to other Latin American countries, where it replaced the development model and prevented the socialist alternative. Neoliberalism was imposed rather than chosen democratically, as exemplified by the coup d'état in Chile. Throughout its implementation, it utilized liberal democracy as a means to achieve its goals. Despite more than two decades in practice, neoliberalism proved unsuccessful but did not disappear entirely.
As a response to neoliberalism, social protests arose, and new democratic governments emerged in countries like Venezuela, Brazil, Argentina, Uruguay, Bolivia, and Ecuador. These governments sought to create a more humane and socially-oriented state. This political experiment was referred to as "21st-century socialism" by Hugo Chávez. Among these leaders, Rafael Correa stood out as the only one who provided a theoretical framework for this form of socialism through his lectures, arguments, and interviews. This essay analyzes, systematizes, and explains these ideas.
The conclusion drawn is that "21st-century socialism" shares similarities with traditional socialism, but it also exhibits significant differences. This analysis is rooted in the ideas of various authors and, subsequently, incorporates Correa's contributions as conveyed in various media sources.

Arrhythmia Classification from ECG Signals Using Transformers and Data Balancing Techniques
Authors: Malūkaitė Jaunė , Bernatavičienė Jolita , Treigys Povilas
Published: May 2024

While many arrhythmias pose minimal threat, certain heart rhythm irregularities elevate the potential for stroke or heart failure. The complexity arises particularly with the supraventricular premature heartbeat which has a resemblance to a normal beat and occurs infrequently. Consequently, this research proposes a data balancing and classification technique that enhances the accuracy of identifying mentioned hard-to-classify heartbeats while maintaining robust metrics for other classes. The study introduces a deep learning framework combined with a multi-head attention transformer, for balancing – under-sampling and synthetic minority oversampling are used. To evaluate the proposed model, various experiments based on real data were conducted. The results were compared with an existing model used in chest belt heartbeat monitoring, and the results show that the transformer model achieved better performance for supraventricular premature heartbeats, at the same time reaching high overall and per-class metrics.
Vairavimo maršruto skaičiavimo, grindžiamo skatinamuoju mokymusi, vizualios aplinkos kūrimas

Published: May 2024

Straipsnyje yra sprendžiamas optimalaus maršruto kelių tinkle paieškos uždavinys. Uždavinys yra modelinis, nes kelių tinklas pasirinktas stačiakampis su vienodomis tiesiomis atkarpomis, o kai kuriose sankryžose yra veikiantis šviesoforas. Uždavinys sprendžiamas naudojantis skatinamojo mokymosi algoritmais. Straipsnyje siekiama palyginti skirtingus skatinamojo mokymosi algoritmus, o taip pat sukurti vizualią aplinką, leidžiančią stebėti skatinamojo mokymosi procesą. Vizuali aplinka yra sudaryta iš automobilio, kelių ir šviesoforų tinklo, bei galutinio finišo. Mokymasis vyksta siekiant minimizuoti pravažiuotų atkarpų skaičių. Algoritmai, sunaudojantys mažiausią tokių atliktų žingsnių skaičių ir tuo būdu randantys sprendimą greičiausiai, yra geriausi. Tyrime buvo naudojami keturi skatinamojo mokymosi algoritmai: Q-learning, Sarsa, Sarsa(λ), Actor-critic. Pasiūlytos realizacijos, labiausiai tinkančios sprendžiamam uždaviniui. Aplinka naudinga susipažįstantiems su skatinamuoju mokymusi ir jo principais. Straipsnyje pateikiama nuoroda į aplinkos programos kodą ir instrukcijos, kaip ja pasinaudoti. Tai turėtų išplėsti skatinamojo mokymosi taikymus.
Resolving Hibah Disputes Involving Shared Property
Authors: Nasution Hotnidah , Muchtar Ahmad Rifqi
Published: May 2024

In the Islamic legal context, hibah has both worship and economic aspects. However, its practice often leads to problems when one or more terms determined by Islamic teachings are ignored. Among the violations in grant practice is granting hibah from property not fully owned by grantor. This paper aims to examine issues in resolving disputes on hibah (property granting) involving a shared property owned by a husband and wife. This study focuses on the examination of two judicial verdicts issued by the Religious Court (Verdict No.354 /Pdt.G/2022/PA.Pt) and the Appellate Religious Court (Verdict No. 222/Pdt.G/2022/PTA. SMG) on hibah dispute where hibah property contains shared property. This study finds that there are two approaches used by the judges in dealing with the issue. First, in the first instance court considered hibah void and revoked hibah. Similarly, the appellate court annulled hibah transaction but considered some part of the property to be rightful for grant. This is because hibah is taken from the property owned by grantor, which has been separated by his wife's property.
ДОСЛІДЖЕННЯ КОМПОНЕНТІВ ЕФІРНИХ ОЛІЙ ЯК ПОТЕНЦІЙНИХ ДЕЗІНФІКУЮЧИХ ЗАСОБІВ ІНГІБІТОРІВ СПАЙК ГЛІКОПРОТЕЇНУ SARS-COV-2

У цій роботі ми поєднали дві мети: створення шаблону для побудови гомологічних моделей рецептор-зв'язуючого домену спайк глікопротеїнів різних варіантів SARS-CoV-2 та його практичне застосування для сканування природних сполук як потенційних дезінфікуючих засобів. Дев'ять варіантів SARS-CoV-2: Дикий тип, Альфа, Бета, Гамма, Дельта, Епсилон, Лямбда, Мю та Омікрон – стали об'єктом цього дослідження. Розглянуто природу взаємодії між білком ACE2 та рецептор-зв'язуючим доменом з метою виявлення критичних для зв'язування амінокислот. В якості прикладу, ряд активних інгредієнтів, які часто зустрічаються в традиційних китайських лікарських засобах, були оцінені за допомогою обчислень на предмет їхньої інгібуючої активності. Результати, отримані в цьому дослідженні, свідчать про те, що метод гомологічного моделювання, випробуваний тут, може бути успішно використаний, коли 3D-структури ще недоступні. Розроблений підхід може бути використаний для моделювання мутантів, кристалічна структура яких ще не відома, та сканування більш широкої бібліотеки сполук проти інших мутованих вірусних білків.
Niemieckie reparacje wojenne za II wojnę światową (polskie kontrowersje)
Authors: Wyszczelski Lech
Published: May 2024

German war reparations were imposed arbitrarily by the victorious powers, because no peace conference was convened. They were estimated at $20 million at the 1938 exchange rate, half of which went to the USSR (the Polish People’s Republic was to receive 15% of its pool). In addition, they were imported by the great powers themselves. Western powers abandoned their importation in the late 1940s, and the USSR, including the Polish People’s Republic, abandoned it in 1953. Both the Federal Republic of Germany and the four superpowers signed the so-called the two plus four agreement in 1990 considered the end of World War II. Poland received only part of the reparations due to it as part of Russian reparations. And so far, financial compensation from the Federal Republic of Germany has not satisfied her. During the PiS government, President Jarosław Kaczyński considered demands for such reparations to be a political issue aimed at weakening the international position of Germany, including the EU, and for his own election campaigns.
