REFLEXIONES SOBRE LA CRITICIDAD DEL MARXISMO Y LA IZQUIERDA LATINOAMERICANA. UN ENFOQUE DESDE LA PERSPECTIVA DEL PENSAMIENTO CRÍTICO
Authors: Mejias Maria Luz 
Published: May 2024

El presente trabajo tiene como objetivo realizar un análisis contextual de la direccionalidad del marxismo latinoamericano desde la muerte de José Carlos Mariátegui hasta nuestros días. Inevitablemente, este empeño tropieza con las diversas formas en que se ha manifestado el pensamiento de izquierda, con sus disímiles proyecciones, y, sobre todo, con la forma en que ha enfrentado los distintos acontecimientos históricos en el continente. En este sentido, el trabajo parte de la forma auténtica de marxismo , cuya expresión más genuina fue el pensamiento de Mariàtegui,asì como los alejamientos posteriores respecto al marxismo clásico, vislumbrados preferentemente en los posicionamientos teóricos de algunas figuras en la etapa controversial del “empobrecimiento” del marxismo en América Latina(1941-1958).Se reflexiona en torno al mantenimiento de esta tradición crítica del marxismo latinoamericano y la forma que entroniza con otras tendencias de pensamiento denominadas que se ubican dentro de la perspectiva del “pensamiento crítico”.
Optimizing the productivity of solutions built with the help of ReactJS and D3 libraries
Authors: Chub Iryna , Demchenko Kateryna 
Published: May 2024

Problem. Recently, the problem of the performance of web applications has become particularly acute. This is due to the complexity of the software and the simultaneous deterioration of the code quality. The work considers important aspects of performance of the client part of the web application, built using the ReactJS and D3 libraries. React is known to deliver a faster user interface than most competitors, thanks to its in-house, performance-oriented development approach. However, when your React application starts to scale, you may notice some performance issues or lag. Internal optimization methods may not be sufficient to support the growing traffic and complexity of a fast-paced, enterprise-level application. This is where the question arises: "How to improve performance in ReactJS?". Next, the article will consider important aspects of the performance of the client part of the web application, built using the ReactJS and D3 libraries. Goal. The purpose of the article is to develop a React component (optimized by a new method) in the form of a graph, whose data changes in real time. Methodology. Analytical research methods and functional programming methodology were used. Results. The paper considers the problem of optimizing a component built using ReactJS and D3. Its feature is the change of state in real time. A new code optimization method is proposed, which allows to minimize the number of renders. The proposed solutions will enable to more effectively use all the capabilities of the D3 functionality when designing a wide range of monitoring and billing systems and automated process management systems. Originality. A method is proposed that will help improve the performance of the React application and reduce the number of re-renders. The method is developed using additional React hooks and using a reference to the current graphic component from the parent. The method is based on the fundamental property of the D3 library - saving its own state this allows you to get rid of unnecessary renders. Practical value. The proposed solutions will allow you to use all the functionality of D3 when designing a wide range of monitoring and billing systems and automated process management systems. D3 has the flexibility to display a large layer of diverse data and allows data visualization using HTML, SVG and CSS.

Published: May 2024

Problem. Technological systems (TS) that are designed, created and operated are increasingly demanding in terms of their productivity, environmental friendliness and cost-effectiveness. The effectiveness of the TS largely depends on its structure and the optimal distribution of work among performers. Existing mathematical models of assignment problems do not allow correct distribution of the flow of work packages according to multiple quality indicators in conditions of non-deterministic input data. This determined the relevance of the scientific and applied task of developing a model for the cyclical distribution of work packages based on a set of indicators, taking into account the workload of the performers and the incomplete certainty of the process parameters. Goal. The goal is to increase the effectiveness of system design technologies of vehicles due to the development of a model of the process of allocation and execution of work packages in the conditions of the stochastic nature of the input flow, multi-criteria decisions, the presence of priorities and prohibitions in the implementation of allocation. Methodology. The process of operation of the TS is presented in the form of a mass service system, which includes the phases of distribution of the package of works, execution and aggregation of works. Optimization methods, utility theories, decision-making, schedules, mass service, simulation statistical modeling were used in the development of the model. A modified Hungarian algorithm was used to distribute the work. Results. A statement was formulated and a model was developed, which implements an adaptive algorithm for multi-criteria distribution of work and a modeling algorithm for determining the functional characteristics of the process. The ratio for the objective functions of financial, time costs and quality, as well as their additive weighted convolution, is proposed. Originality. An analytical-simulation model of multi-criteria distribution and execution of TS work packages has been developed, which takes into account the stochastic nature of incoming flows, their execution time, and the current state of the executors. Practical value. The obtained results make it possible to increase the efficiency of structural and technological optimization technologies of TS in the processes of their design, reengineering or management due to the reasonable distribution of work packages taking into account cost, productivity and quality indicators.

Published: May 2024

The traditional Javanese songs created by Sunan Kalijaga, especially Lir ilir and Kidung Rumekso ing Wengi, have tremendous philosophical depth when associated with Javanese culture. Therefore, this research aims to explore and analyze the philosophical meaning contained in the two previous songs and find out how the spiritual messages in these songs are still relevant to the state of society in the modern era. This research uses Ferdinand de Saussure's semiotic analysis to find out the deeper meaning of the text, not forgetting to also use the cultural context approach, to minimize irrelevant interpretations. For data validation, this research uses the triangulation method, where the data comes from interviews, historical records, and direct observation. In practice, the point is to explore the messages contained in the two songs, which are all sourced from the lyrics of these songs and the opinions of experts. The results show that both songs contain philosophical teachings on how to achieve wisdom and peace in every episode of human life. They also teach about the importance of establishing a good relationship with God. In addition, this study also revealed that the spiritual messages in these two songs are still relevant as a reflection of the spiritual journey of everyone in the modern era.

EXPLORING FOREIGN LANGUAGE TEACHER BELIEFS AND PRACTICES IN TURKEY: A CASE STUDY
Authors: BABABAYLI Isgandar , KIZILTAN Nalan 
Published: May 2024

This case study explores the relationship between an Italian as a foreign language teacher’s beliefs and online teaching practices in a tertiary education setting during the Coronavirus (COVID-19) Pandemic. Specifically, it aims to find out the teachers’ beliefs with regard to their professional identities, and their roles in foreign language teaching classrooms. Besides, it was discussed if the teachers’ beliefs concerning their role identities are related to their classroom practices. Data were collected over an academic term through one semi-structured interview and two observations conducted at beginning and at the end of the semester in order to see if there are any differences according to the professional roles of the instructor in the course of time depending on the learners’ enhanced Italian language competence. The findings of the study revealed that the instructor acted out as a manager, facilitator, input provider, motivator and a translator in two observations, showing a slight difference in degree of synchronous interaction among the instructor and the students with the printed text, video tape or Web site. The interview responses revealing the instructor’s beliefs were correlated with the roles observed in synchronous communication. This study is limited to the online foreign language classroom. It would be interesting to observe what other roles the teachers play in the face-to-face classroom. It may be suggested that the studies investigating those of teachers instructing foreign languages other than English may enlighten the research on teachers’ beliefs and their professional role identities and contribute to the professional development of foreign language teachers. Last but not least, for professional growth of pre-service foreign language teachers, preliminary studies on teacher cognition should be included in the curriculum of teaching practicum.

Published: May 2024

Introduction: In recent research, the expansion in the use of Mg alloys for biomedical applications has been approached by modifying their surfaces in conjunction with micro-arc oxidation (MAO) techniques which enhance their abrasion and corrosion resistance.Methods: In this study, combining laser texturing and MAO techniques to produce the dense ceramic coatings with microstructures. On the surface of the AZ31 Mg alloy, a micro-raised annulus array texture has been designed in order to increase the surface friction under liquid lubrication and to improve the operator’s grip when holding the tool. For this work, the micro-morphology of the coatings was characterised, and the friction properties of the commonly used scalpel shank material 316 L, the untextured surface and the textured surface were comparatively analysed against disposable surgical gloves.Results and discussion: The results show that the Laser-MAO ceramic coating grows homogenous, the porosity decreases from 14.3% to 7.8%, and the morphology after friction indicates that the coating has good wear resistance. More specifically, the average coefficient of friction (COF) of the three types of gloves coated with Laser-MAO ceramic was higher than that of the 316 L and MAO ceramic coatings under the action of the annulus-integrated texture under the lubrication conditions of physiological saline and defatted sheep blood, which achieved the goal of increasing friction for the purpose of helping to prevent the problem of tool slippage from the hand.

Published: May 2024

BackgroundThe objective of this study was to explore the association between the ratio of serum creatinine to cystatin C to waist circumference (CCR/WC) and hypertension.MethodsThe study utilized data extracted from the China Health and Retirement Longitudinal Study. In the cross-sectional analysis, logistic regression analyses were employed to examine the association between the CCR/WC ratio and hypertension. By utilizing restricted cubic splines, potential non-linear associations between the CCR/WC ratio and hypertension were explored. In the longitudinal analysis, the association between CCR/WC quartiles (Q1–Q4) and the risk of new-onset hypertension was evaluated by Cox proportional-hazards models.ResultsIn total, 7,253 participants were enrolled. The study unveiled an inverse association with hypertension, demonstrating an odds ratio (OR) of 0.29 (95% confidence interval [CI]: 0.23–0.37, P &lt; 0.001). Among males, an OR of 0.38 (95% CI: 0.25–0.58, P &lt; 0.001) was observed, while among females, an OR of 0.41 (95% CI: 0.28–0.60, P &lt; 0.001) was noted. There was an absence of a nonlinear association between the CCR/WC ratio and hypertension. Cox regression analysis unveiled a reduced risk of hypertension in Q3 (Hazard ratios [HR]: 0.69, 95% CI: 0.58–0.82, P &lt; 0.001) and Q4: (HR: 0.70, 95% CI: 0.59–0.83, P &lt; 0.001) in compared to the Q1 of the CCR/WC ratio, and sex-specific analysis yielded consistent results.ConclusionThis study emphasizes the potential association between an elevated CCR/WC ratio and a reduced risk of hypertension.
