Authors:   College of Computers and Information Systems, Umm Al-Qura University, Makkah, Saudi Arabia, Samrgandi Najwa
Published: December 2023

Mobile learning tools have facilitated authentic learning experiences, allowing students to forge meaningful connections while acquiring real-world knowledge. Mastering the skill of using mobile video conferencing applications is crucial but often complicated for users, such as students, teachers, and employers. In this study, the mobile video conferencing applications Zoom and Webex were compared with respect to their usability, using cognitive load theory as the conceptual framework. A systematic mapping approach was applied to obtain comparative descriptive information from surveyed literature. The available literature on communications support, accessibility and usability, and privacy and security of video conferencing technology was used for the systematic mapping process. The literature review revealed that Zoom and Webex usage can lead to cognitive fatigue, so users must avoid multitasking and schedule breaks between sessions to remain focused. Furthermore, video conferencing tools need to bridge the gap between usability and security for augmented safety of personal information alongside user comfort. Overall, the findings of this study are important for reducing the complexities of mobile video conferencing applications and enhancing the mobile learning experience.

The approach to the synthesis of cerium oxide nanoparticles (CeO2NPs) using plants as capping agents has been widely researched because of its eco-friendly, low-cost, simple, effective, and reusability. In this research, we used Moringa oleifera leaf extract-mediated CeO2NPs. CeO2NPs were characterized by XRD, FTIR, SEM, TEM, and DRS UV-vis. The photocatalytic activity of CeO2NPs was tested using a phenol dye concentration of 7 mg/L with variations in photocatalyst weight of 10, 20, 30, 40, 50, 60, 70, 80, 90, and 100 mg under UV irradiation, respectively, with time variations of 15, 30, 45, 60, 75, 90, 105, 120, 135, and 150 min. SEM and TEM morphology results showed that the CeO2NPs were spherical and agglomerated. The crystal structure is cubic, with a crystal size of 18 nm with a band gap of 2.87 eV. CeO2NPs showed high photo-degradation phenol dye of 94.45% under visible light in 120 min irradiation time. The results show that M. oleifera leaf extract could be as inexpensive and safe for synthesizing other metal oxide nanoparticles, potentially having applications in the biomedical and environmental fields.

Published: December 2023

In this work, new compounds of amide derivatives (C1-C3) were synthesized through the conversion reaction of p-chloroaniline to diazonium salt (B1), which reacts with aniline to form a new azo-compound (B3). Synthesized of p-alkoxybenzoic acid (A1-A3) and reacts with SOCl2 to form A4-A6 compounds that react with B3 compound to form amide compounds (C1-C3). The synthesized derivatives were tested by docking analysis and characterized via FTIR, 1H-NMR spectra. In the docking study, the interaction diagram also displays many van der Waals interactions, which are used to estimate the synthetic compounds' activity as insecticides like anti-termites. Heptyl came in first on the binding score, followed by octyl and then nonyl. Due to the compounds' modified conformation in interacting with the enzyme's binding pocket, the length of the alkyl residue of the derivative adversely impacted their binding inhibition. The synthesized compounds (C1 and C3) give a good result as anti-E. coli and anti-Staphylococcus strains.

A plastic composite consisting of polylactic acid (PLA), linear low-density polyethylene (LLDPE), oleic acid-grafted linear low-density polyethylene (LLDPE-g-OA) compatibilizer, and organo-precipitated calcium carbonate (O-PCC) have been successfully made in the molten state. This study aims to characterize the mechanical, physical, thermal, and morphological characteristics of the PLA/LLDPE/O-PCC plastic composite in the presence of an LLDPE-g-OA compatibilizer. The plastic composite was prepared by blending PLA, LLDPE, LLDPE-g-OA, and O-PCC using an internal mixer with a heating of 160 °C and a rotation of 100 rpm. LLDPE and LLDPE-g-OA are put together into the inner mixer chamber until melted, followed by PLA and O-PCC. The most optimum plastic composite composition is PLA/LLDPE/LLDPE-g-g-OA/O-PCC (67.5:22.5:5:5). The mechanical properties showed an increase in tensile strength of 9.78 MPa. The physical properties showed that the minimum water absorption was 0.74%, the biodegradation in humus soil showed a degradation rate of 0.09% per day, and the thermal properties showed better stability with a melting point of 146.5 °C. The FTIR spectrum is similar to the polymer blend without O-PCC. The morphology indicates that the composite is compatible and homogeneous. This semi-biodegradable plastic composite has significant implications for reducing the accumulation of plastic waste in the environment.

This work focuses on synthesizing new imidazolin-4-one derivatives (2a-c), akin to leucettamine B analogs, via microwave-assisted transamination reactions. This reaction was carried out between 3-alkyl-5-dimethylamino-2-thioxo-imidazolidin-4-one (1a-c) and aniline. The structural integrity of the synthesized compounds was confirmed using NMR and MS spectroscopy, and their configurations were validated through DFT calculations. Analyses encompassed molecular electrostatic potential, frontier molecular orbitals, HOMO-LUMO energies, energy band gap, and global chemical reactivity descriptors, providing comprehensive insights into their characteristics. The investigation extended to the biological domain, employing substance activity spectra prediction (PASS) and molecular docking with Autodock Vina4 program. Notably, this holistic assessment aimed to gauge the potential regulatory effect of the compounds on cholesterol. This integrated approach contributes to compound design understanding and potential applications, spanning drug design and broader biomedical contexts.
Ficciones Constitucionales. Elementos introductorios para el estudio de las ficciones jurídicas en las Constituciones del nuevo constitucionalismo latinoamericano
Authors: Fuentes-Contreras Édgar Hernán , Cárdenas Contreras Luz Eliyer
Published: December 2023

El derecho, como lenguaje, cumple diferentes funciones comunicacionales que logra, en buena medida, a través del uso de herramientas y dispositivos narrativos. Entre ellos se destacan las ficciones jurídicas, las cuales, lejos de retratar la realidad, buscan crear una verdad jurídica. En el caso de las ficciones constitucionales, éstas son, con frecuencia, malinterpretadas, lo que lleva a su degeneración. En este texto, más allá de ofrecer un acercamiento conceptual a la figura de las ficciones constitucionales, se ofrece un análisis introductorio en cuanto a la forma en la que ha ocurrido esto en el contexto del nuevo constitucionalismo latinoamericano.

Published: December 2023

The tremendous development of IT requires auditors to be equipped with IT knowledge and tools to navigate the rapid development of e-government in public sectors, supporting the nation’s transformation agenda. However, the audit technology used by public sector auditors remains underutilized. This study examines Malaysian public sector internal auditors’ readiness for digital auditing. Questionnaires were distributed to 149 internal auditors, and the data were analyzed using PLS-SEM. Findings revealed that only technological and environmental factors were found to have a significant influence on the readiness of internal auditors to utilize digital auditing in their jobs, whereas organizational factors had no significant influence. The findings are anticipated to enrich the body of knowledge on the readiness of Malaysian public sector internal auditors to embrace digitalization as part of their routine. Understanding determinants is crucial for authorities to ensure digital economy players, including public sector internal auditors, are technology-ready for digital competencies.

Objective: We aimed to assess the relationship of body weight time in target range (TTR) with composite kidney outcome in people with overweight/obesity and type 2 diabetes mellitus (T2DM).

Research Design and Methods: 3,601 participants with baseline estimated glomerular filtration rate (eGFR) ≥60mL/min/1.73 m2 from the Look AHEAD (Action for Health in Diabetes) trial were included. Body weight TTR was defined as the proportion of time during the first 4 years that body weight was within the weight loss target (a weight loss of at least 7% from baseline). The primary outcome was composite kidney outcome, defined as eGFR decline at least 30% from baseline and to a level of less than 60 mL/min/1.73 m2 at follow-up visit, or end-stage kidney disease.

Results: During a median follow-up of 8.0 years, 435 cases of composite kidney outcome were documented. Body weight TTR during the first 4 years was inversely associated with the subsequent risk of composite kidney outcome (Per SD increment; adjusted HR:0.81, 95%CI: 0.70-0.93). Accordingly, the adjusted HRs (95% CI) of composite kidney outcome were 1.00 (reference), 0.73 (0.54-1.00), 0.71 (0.52-0.99), and 0.54 (0.36-0.80) for participants with body weight TTR of 0%, >0% to <29.9%, 29.9% to <69.7%, and 69.7% to <100%, respectively. Similar results were found for a doubling of urine albumin-to-creatinine ratio (secondary outcome).

Conclusions: A higher body weight TTR, with a weight loss target of losing at least 7% of initial weight, was associated with a lower risk of kidney outcomes in participants with overweight/obesity and T2DM.

Actualization of Bodily Aspect as Means of Reconstructing Socialist Realist Discourse in Novel “Librarian” by M. Elizarov
Authors: Kuryaev I. R. , Trushkina A. O.
Published: December 2023

The ways of representing violence and the role of this category in constructing socialist realist discourse are considered. The novel “The Librarian” by Mikhail Elizarov is chosen as the research material. It is established that the novel synthesizes the tradition of socialist realist novels and genre elements of popular literature, with the author placing emphasis on the representation of violence. The article highlights that violence in the novel is visual and cinematic. It is revealed that the protagonist of the novel plays a significant role in such representation, as the artistic world is demonstrated through their perspective. The article shows that the acts of violence presented in the novel become indexes of a particular “Gromovian” world and contribute to the visual and ideological transformation of characters, as well as an inversion of familiar oppositions. The authors of the article determine that the “Gromovian” world is formed around the Book, which actualizes ideas of the periphery and the “golden age”: it is here where violence becomes a legitimate means of communication with characters from both the “Gromovian” and ordinary worlds. It is noted that violence, both physical and psychological, forms fundamental oppositions in the “Gromovian” world, such as “own” versus “other”, “senseless world” versus “ideal world”, and so on. Finally, it is pointed out that through violence, the socialist realist plot about the “remaking” of the hero and their rejection of their own self for the collective “we” is realized.
Image of “Fallen Woman” in Novels of G. Fallada’s “Wolf Among Wolves” and F. M. Dostoevsky’s “Crime and Punishment”: Comparative Analysis
Authors: Melnikova L. A.
Published: December 2023

The image of the “fallen woman” in the novels of G. Fallada’s “Wolf Among Wolves” and F. M. Dostoevsky’s “Crime and Punishment” is examined. Traces of the literary influence of the Russian classic on the poetics of the German writer’s novel at the thematic and character levels are identified. It is established that the key motif in both works is the theme of moral resurrection of the fallen individual. It is shown that, in addressing the problem of the “humiliated and insulted”, both authors incorporate the image of the “fallen woman” into the system of characters in their novels. It is noted that the writers pay special attention to the reasons for her social downfall. Through the use of comparative-historical analysis, parallels in the images of “fallen” women presented in these works — Petra Ledig and Sonya Marmeladova — are identified. The author of the article concludes that the heroines share a number of common features: Christian semantics of their names, moral purity despite physical vice, a tendency towards selfsacrifice, great inner strength despite outward timidity, a desire to show mercy, the ability to motivate their loved ones towards spiritual rebirth and thereby “rebirth” themselves. The results of the study allow to demonstrate the significance of F. M. Dostoevsky’s humanistic ideas for the aesthetic principles and worldview position of G. Fallada in the novel “Wolf Among Wolves”.
Current Linguistic Situation in Village of Sebyan-Kyuyol in Kobyai District of Republic of Sakha (Yakutia)
Authors: Zakharova L. O.
Published: December 2023

This paper examines the linguistic situation in the village of Sebyan-Kyuyol in the Kobyai district of the Republic of Sakha (Yakutia), where the Lamunkhin Even people, one of the indigenous minority groups of the North, reside. The focus is on the structural and substantive characteristics of the linguistic situation. Data was obtained through participant observation and sociolinguistic surveys among 81 respondents from various age, gender, and social groups of the Even community. Using a comprehensive approach that includes linguistic and social aspects, the distribution and functions of Even, Russian, and Yakut languages in different spheres of communication are analyzed. It is shown that the linguistic situation is three-component, with the Even language being dominant but facing some challenges from Russian and Yakut languages in certain spheres, as well as among the younger generation who show less interest in their native language. Factors influencing the viability and maintenance of the Even language are identified. Problems and prospects for its development are revealed. It is established that the linguistic situation in Sebyan-Kyuyol village is relatively favorable and stable, but requires constant attention and support from the government and community.
Ekaterinburg (Sverdlovsk) During NEP Years: Organization of City Government System
Authors: Vorobyov S. V.
Published: December 2023

The article discusses the activities of various levels of government structures (city council, gubernatorial, district and regional executive and party bodies) in managing EkaterinburgSverdlovsk during the NEP years. It is established that during this period, the central government was faced with a choice between centralism or decentralization in local governance and the delineation of powers between councils and different levels of regional government. It is noted that in practice, a multilevel system of city management was formed, which had both positive and negative aspects. It is shown that on the one hand, in conditions of weak city authority and a shortage of city budget, the intervention of regional authorities in urban issues and financial injections from their side allowed for the successful resolution of acute urban economic issues. On the other hand, such a system of power significantly limited the authority of the city council, pushing it to other government structures. As a result, the author concludes that the city council was not a full-fledged, independent administrative unit, and its competence in managing the city was significantly limited. This situation is explained by the fact that the main decisions regarding the directions of city development were made by regional authorities, which did not always positively affect the effectiveness of urban management.
Freedom of Conscience in Russian Empire at Beginning of 20th Century and Constitutional Reform of 1906
Authors: Kulikov S. V.
Published: December 2023

For the first time in scientific historiography, with the involvement of previously unknown archival documents, the problem of ensuring freedom of conscience is considered when creating the Fundamental Laws on April 23, 1906, which became the first national constitution in force. It is shown that P. A. Kharitonov, A. P. Salomon and Count A. F. Heyden paid attention to this problem, that is, the authors of bureaucratic drafts of new Fundamental Laws, which by December 1905 were prepared for Emperor Nicholas II. The main one turned out to be Kharitonov’s project, considered at a Meeting of the highest ranks of the State Chancellery. In the future, the consolidation of freedom of conscience in the Fundamental Laws was facilitated by the discussion of the draft State Chancellery in the Council of Ministers under the chairmanship of Count S.Y. Witte in March 1906 and the drafting of another draft of Fundamental Laws by Professor O. O. Eichelman at the same time. It is emphasized that the controversy that arose as a result of the April Special Meeting chaired by Nicholas II among his key figures about the limits of freedom of conscience influenced the final version of the corresponding article of the Fundamental Laws established personally by the tsar. It is concluded that this version reflected the conservative-liberal nature of the views shared by the direct participants of the constitutional reform of 1906.
Pension Provision for Muslim Clergy in Asian Part of Russian Empire (19th — Early 20th Century)
Authors: Nedzelyuk T. G.
Published: December 2023

The issue of granting pension benefits to Muslim clergy and their families in the Russian Empire is considered, as well as the characteristics of state-confessional policy in Russia both in the historical past and at the present stage. The aim of this study was to identify similarities and differences in the pension provision of Orthodox and Muslim clergy. Attention is paid to the socio-cultural status and material situation of clerics in border regions and national autonomies of the Asian part of Russia. Previously unstudied materials from the archives of the Russian State Historical Archive, the Russian State Historical Archive of the Far East, and the Central State Archive of the Republic of Kazakhstan are introduced into circulation. The novelty of the study lies in both the topic itself and the previously unexplored source base. Comparative, comparative-historical, and analytical research methods contributed to the realization of the research plan. The results obtained in the process of analyzing documents testify to a balanced approach and tolerant attitude towards clerics — representatives of “recognized” religions in the Russian Empire. The conclusion is formulated that the size of the pension depends on the length of service, but not on the religious affiliation of the clergy.
Domestic Reindeer Herding in Arctic Regions of Yakutia in Second Half of 1990s: Experience of Decision-Making on Socio-Economic Issues in Industry
Authors: Sannikova Ya. M.
Published: December 2023

The experience ofsolving social and economic problems related to domestic reindeer herding in the Arctic regions of Yakutia during the early post-Soviet period is being studied. Attention is given to the adoption of the first program document in the republic— Resolution No. 521, dedicated to comprehensive support for traditional industries and social protection of workers in the Arctic regions. Archive documents on the activities of the relevant ministry in developing recommendations on wage payment in reindeer herding, adopting new decisions on one-time payments to reindeer herders and tent workers, and statistical data on some general economic indicators in reindeer herding are presented. The approach to calculating labor standards for reindeer herders and attempts at their social protection through professional tariffication of wage payment are presented in detail. Social directions included officially in the program for the development of domestic reindeer herding are highlighted. At the local level, it is shown that representatives of the relevant ministry responsible for managing traditional industries could not always rely on a positive experience in making decisions on socio-economic development of domestic reindeer herding as a leading traditional occupation of indigenous people, but they were fully aware of the real social situation of workers in the industry.
Contrasts of Quantification in Lexical Series ‘Post, Poschenie, Postitisya — Alkanie, Alchba, Alkati’ in Old Russian Manuscripts (Historical Corpus ‘Manuscript’)
Authors: Zholobov O. F.
Published: December 2023

The article presents an analysis of the distribution of lexemes from synonymous series ‘post’, ‘poschenie’, ‘postitisya’ and ‘alkanie’, ‘alchba’, ‘alkati’ in Old Russian manuscripts. The study is based on a corpus-based and quantitative approach, using the historical corpus ‘Manuscript’. The contrasts of quantification of the mentioned lexical series were first established in the study. The data from four sub-corpora — Gospels, Apostle, Parimeynik and chronicles were considered. It was found that synonymous relationships of lexical series are present only in the full-aprakos Gospel. In the service Four-Gospel and shortaprakos Gospel, only lexemes from the first series are used, while lexemes from the second series have meanings of ‘hunger’ and ‘to hunger’. Lexemes from the first series are also preserved in the Cyril-Methodius translation of the Apostle. In the Preslav translation of Tolstovsky Apostle from the 14th century, lexemes from the first series are consistently replaced by lexemes from the second series. The Parimeynik sub-corpus, whose oldest translation has Cyril-Methodius origin, is contrasted with texts from other sub-corpora by the absence of lexemes from the second series in the meanings of ‘fast’ and ‘to fast’ in all editions. The Tale of Bygone Years proves the early establishment of lexemes from the first series in Old Russian tradition. A quantitative contrast is observed in the Suzdal chronicle, where, unlike other chronicles, lexemes from both series are presented.

Authors: Rubio Perea Engracia María
Published: December 2023

n este artículo se presenta una propuesta de enseñanza de los recursos educativos abiertos (REA) llevada a cabo en la formación inicial docente, basada en: el conocimiento y revisión de una selección de materiales educativos digitales para su futuro uso y adaptación en la clase de Lengua en Educación Secundaria; la elaboración de un diseño de REA como procedimiento de evaluación; y, finalmente, la cumplimentación de una encuesta de valoración de la intervención realizada. Los resultados obtenidos muestran que la mayoría de los estudiantes percibieron los REA como una propuesta innovadora y recomendable para mejorar su práctica en el aula, aunque también revelaron que se trata de una actividad compleja que necesita de un acompañamiento guiado. El desconocimiento de los REA y cierta inseguridad a la hora de emplearlos y adaptarlos a sus diferentes contextos fueron percibidos como algunas de las principales dificultades. A partir de estos resultados iniciales, se propone una línea de investigación que necesita de un contexto de estudio más amplio para elaborar nuevas estrategias en la formación inicial del profesorado que permitan el empleo de estos recursos en sus prácticas docentes.

Published: December 2023

Vinculado al intento de la sociedad de ajustarse a la pandemia de la Covid-19, han surgido nuevos retos en todas las esferas de la vida. La presión de adaptar la labor educativa en una sociedad con restricciones fue, mayoritariamente, tarea del personal docente. El objetivo del presente artículo es realizar una trasferencia positiva del conocimiento de la tecnología educativa, tanto dentro como fuera de los tiempos de la pandemia. El artículo presenta dos análisis cualitativos sobre la preferencia de la tecnología por parte de los docentes. El primero se basa en la interpretación de los datos recogidos, sometidos a cálculo cuantitativo con el software EXCEL, para conseguir las frecuencias de uso de una u otra tecnología. El segundo análisis interpreta la tecnología por grupos temáticos, basados en su función. El estudio muestra que la educación/enseñanza a distancia ha pasado por muchos cambios causados por la pandemia. La tecnología ayudó a la educación/enseñanza a continuar a pesar de la pérdida de lo físico, y la tecnología educativa, especialmente las soluciones basadas en páginas web, han facilitado a los docentes el camino a seguir para mantener y mejorar la calidad del mismo proceso educativo. Comparando con el pasado durante el cual los instrumentos de educación a distancia se habían utilizado asincrónicamente, la pandemia ha posibilitado el uso de posibilidades interactivas y portátiles más colaborativa y comunicativas. También ha incrementado la variedad de los propios instrumentos. Ahora existe más de una solución para cubrir la misma o parecida función. El artículo trabaja una extensa cantidad de datos para responder la pregunta “¿qué tecnología educacional empleas?”. Las respuestas las facilitaron profesores, maestros, entrenadores, estudiantes y otras personas interesadas, todo ello para poder ofrecer luego sugerencias para la práctica de una enseñanza más global.
Acceptance and use of cloud-based virtual platforms by higher education vocational school students: application of the UTAUT model with a PLS-SEM approach
Authors: Sayginer Can
Published: December 2023

Cloud-based virtual platforms emerged as a new way of tracking lectures as mobile, reliable, and productive. Especially due to the COVID-19 breakdown, they became popular because checking the students’ effort, performance, social interaction among each other, and the condition of vocational schools was easy to track during and after the online classes. The research aims to analyze the behavioral intention to adopt cloud-based virtual platforms such as Blackboard, Microsoft, Zoom, Edmodo, Sakai and Moodle during COVID-19. 14 questions were asked to 313 students from higher education vocational schools in the district of Izmir, Turkey via Google Forms. PLS-SEM analyses were made by SmartPLS 4.0 software and by proposing the Unified theory of acceptance and use of technology (UTAUT) theory. The results showed that the variance of effort expectancy, behavioral intention, and facilitating conditions explained 76.00% of the proposed model. The research contributes to understanding the students’ behavior toward the acceptance of cloud-based virtual platforms in case of new variants or other epidemic diseases emerged in the future.

Authors: Deveci Topal Arzu , Kolburan Geçer Aynur
Published: December 2023

Student satisfaction is one of the foremost factors for e-courses to continue efficiently and achieve their goals. The present research aims to analyze the clustering tendencies of e-course students’ satisfaction with e-courses according to the variables of “gender, class, computer ownership, computer and internet literacy, duration of internet use, the connection type to the internet, and the tools utilized by the students in the learning management system” through clustering algorithms, one of the data mining techniques. The survey model was employed. A 35-item satisfaction scale devised for students taking e-courses was used for data collection. A total of 522 students taking online courses at a university participated in the study. Descriptive statistics and cluster analysis were employed to analyze and interpret the data. As a result of the analyses through K-Means cluster analysis, four different clusters were obtained. Those clusters were defined in accordance with the variables they included as follows: Cluster 1 (the group with the highest rate of computer ownership and the highest computer literacy); Cluster 2 (the group with the lowest rate of computer ownership and the lowest computer literacy); Cluster 3 (students have low computer literacy and low duration of Internet use), and Cluster 4 (the group with the highest rate of females, first graders, and those who use the Internet at “good” and “very good” levels) . According to the research results, the mean student satisfaction levels regarding e-courses were determined to be low in general. As per the clustering analysis, it was observed that the students in Cluster 1 and Cluster 4 had the highest mean values of satisfaction with e-courses and a “good” level of satisfaction compared to the other groups, while Cluster 2 had the lowest mean value. Cluster 3, on the other hand,  was the one with a “medium” level of satisfaction.

This mixed-methods study explored the attitudes of 199 English as a Foreign Language (EFL) special education teachers towards using ChatGPT for language learning. The survey questionnaire, consisting of 21 items, examined attitudes, effectiveness, barriers, and the future use of ChatGPT. The results revealed that participants held moderate attitudes, perceiving ChatGPT as moderately effective with moderate barriers. While no significant differences were found between male and female teachers in attitudes and effectiveness, significant gender differences emerged in the future use of ChatGPT, with female teachers exhibiting a greater willingness to embrace it. Follow-up email interviews with five participants provided valuable insights into strategies, effectiveness, challenges, and inclusivity when using ChatGPT in language instruction for special education students. These findings contribute to implementing and developing ChatGPT as a language learning tool for EFL special education students, emphasizing the importance of gender-inclusive approaches and practical considerations to enhance its efficacy.

El interés por los LMOOC (Language Massive Open Online Courses) ha aumentado en términos de investigación y número de cursos ofrecidos, por su potencial para el desarrollo de los procesos formativos y para trabajar estos contenidos con tecnologías. Situando el interés en las publicaciones realizadas sobre LMOOC en China, este estudio pretende analizar bibliométricamente dicha producción científica en Scopus. La muestra final quedó conformada por 134 publicaciones, siendo analizados con diferentes técnicas bibliométricas (acoplamiento bibliográfico, co-citación, co-ocurrencia). Los resultados señalan una producción científica estabilizada desde sus inicios en 2014, con un mayor desarrollo en los años de la pandemia COVID-19. Predomina la indexación en las áreas de ciencias de la computación y sociales. Predominan las contribuciones a congresos y los artículos. Las publicaciones más citadas se centran en revisiones sistemáticas, autonomía del alumnado y metodologías activas combinados con LMOOC. Otras publicaciones influyentes ponen el foco en definir los criterios de calidad para realizar un LMOOC y el factor emocional en el desarrollo de estos cursos. Entre las potenciales futuras líneas, destacar la adopción de formatos más personalizados como los SPOC o la inclusión de metodologías como el aula invertida. Se concluye que este estudio sobre la producción científica permitirá desarrollar nuevas líneas de investigación sobre los LMOOC a partir de lo existente.
Empobrecimiento e intoxicación de cuerpos-territorios en zonas cultivadas con coca y marihuana en Colombia

Published: December 2023

En Colombia, la expansión de la frontera cocalera y la política antinarcóticos han estado atravesadas por diferentes tipos e intensidades de violencia. Entre la prolífica literatura producida recientemente, menos estudiadas se encuentran las violencias asociadas al modelo agrario disputado en las geografías cocaleras, vacío que abordamos en el presente artículo. Situado en la ecología política latinoamericana, nuestro análisis se centra en tres fuerzas del cambio agrario local: el acaparamiento de tierras que ha dejado a los habitantes de las laderas cada vez más empobrecidos y forzados a buscar en los cultivos de uso ilícito alternativas económicas; la monoculturización de la producción agrícola legal e ilegal como determinante de la mayor utilización de agrotóxicos; y la utilización de agrotóxicos, práctica en que las mujeres estarían viviendo una exposición diferenciada a sustancias químicas de alta peligrosidad asociada a su trabajo agrícola y a su rol doméstico. Se toma como caso de referencia el municipio de Miranda, en el Norte del Departamento del Cauca, región donde realizamos una investigación activista entre 2017 y 2021. Con entrevistas, estancias en campo y la caracterización del modelo agronómico de ocho unidades productivas de cultivos lícitos e ilícitos, nuestros hallazgos problematizan las geografías cocaleras desde las subjetividades de los/as cultivadores. Concluimos que en los cultivos de uso ilícito se emplea una menor cantidad y tipos menos intoxicantes de plaguicidas, comparados con los de mayor peligrosidad aplicados a cultivos legales en la misma región. En consecuencia, alertamos sobre la violencia lenta provocada por los programas de sustitución voluntaria cuando se coacciona a los/as cocaleros a transitar hacia un modelo más dependiente e intoxicante de producción agrícola.

Published: December 2023

Introduction. Intermittent hypoxia-hyperoxia therapy can contribute to increasing exercise tolerance in patients with cardiovascular, bronchopulmonary, metabolic, and neuropsychiatric pathologies, according to studies in the specialized literature. This therapy consists of the use of hypoxic intervals, interspersed with hyperoxic episodes.

Material and methods. We present 7 clinical cases of patients admitted to the Balneal and Rehabilitation Sanatorium of Techirghiol (SBRT) for 2 weeks, complaining of polyarticular mechanical pain. These patients were diagnosed with chronic obstructive pulmonary disease (COPD) by the pulmonologist according to the GOLD criteria. During hospitalization, the patients underwent a complex balneo-physical-kinetic treatment, simultaneously with intermittent hypoxia-hyperoxia therapy. Patients were evaluated both at admission and discharge.

Results. The evolution of the patients was favorable, with improvement in symptoms, spirometry, scales used, 6-minute walk test, HTi index and paraclinical investigations. Improvements were identified in respiratory volumes, but also in total serum cholesterol and blood glucose levels.

Conclusions. Obtaining promising results gives indications that intermittent hypoxia-hyperoxia therapy can be an alternative treatment for multiple pathologies, including COPD. The therapy proved to be safe and well tolerated, representing a non-pharmacological therapy that can be included in the therapeutic management of patients with COPD.
Bufo Rana in Homeopathy: Potentization, Toxicology, Clinical Consequences, and Therapeutic Use
Authors: Bjørklund Geir , Storchylo Olha
Published: December 2023

Homeopathy, an alternative treatment method based on the principle of “like cures like,” has gained attention in recent years. This paper focuses on Bufo Rana, a homeopathic remedy prepared from the poison of the Bufo toad. We explore the process of potentization and dosage in homeopathy, discussing the various potencies and the influence of Avogadro’s number. Furthermore, we provide an overview of Bufo species, their historical depictions in art, and the toxicological properties of bufotenine, tryptamine, and bufotoxin found in Bufo toads. The clinical consequences of the Bufo species’ venom, including neurological manifestations and cardiac arrhythmias, and the therapeutic use of Bufo Rana in mental and neurological conditions are discussed. We summarize Bufo Rana’s symptoms and therapeutic relationships based on William Boericke’s materia medica. Further research is warranted to investigate the efficacy and safety of Bufo Rana and its role in treating specific conditions.
Studies and Perspectives on the Types of Corrosion Occurring in Continuous Chromium Plating Plants

Published: December 2023

Corrosion damage to metal materials is often related not only to metal loss but also to the decommissioning of components from the installations, the replacement and installation of which costs about 3% per year of the cost of the material from which they are made.

The effects of galvanic corrosion on the operation of plants and equipment can be anticipated, observed and controlled. Following an economic analysis and the works to be carried out, a balance can be struck between the impact of corrosion of the mechanical elements in the chrome plating bath and the costs for its prevention. The prevention of corrosion at the design stage can lead to lower annual corrosion-related costs, which are much lower than the costs of remedying the causes when the construction of equipment and plants has already been completed.

The aim of this study is based on an analysis of the effect of electrochemical processes in the chromium plating solution on the copper anode bar in continuous chromium plating plants. Initially the forms of corrosion damage to the metal material were identified and then attempts were made to develop methods to reduce and avoid their destruction.
The Influence of the Stiffness of a Hyperstatic Elastic Beam on the Internal Forces Diagrams and on the Bending Deformations
Authors: Marin Cornel
Published: December 2023

An algorithm using the step function Φ(x-a) from the MATHCAD professional calculation program was used to calculate the bending deformations of an elastic beam suspended by means of tie rods (cables). It allowed the writing of analytical relations of shear and bending internal forces in the beam subjected to bending and the drawing of the corresponding diagrams. Also, the algorithm allowed the writing of the analytical relations of the deformations of the beam (arrows and rotations) with the help of the loading function Ψ (x), respectively its derivative Ψd(x). The numerical simulation presented in this paper allowed finding the practical solution for the proposed problem.

Published: December 2023

The paper presents the results of research on the impact of national culture, big five personality traits, and emotional intelligence on job performances and organizational commitment in teleworkers in West Balkan countries. These impacts were also determined for employees in conventional working arrangements, which enabled a comparison of the results for these two groups of respondents. The research was conducted in the countries of the West Balkan and included 313 respondents. National culture and emotional intelligence have a greater impact on job performances and organizational commitment for employees in conventional working arrangements than in teleworkers. Big five personality traits in some cases affect stronger for employees in conventional working arrangements, while in some cases they affect more powerfully in teleworkers. Teleworkers are less influenced by the environment, and thus less influenced by national culture. Also, teleworkers have fewer opportunities to use emotional intelligence in achieving business goals.
