Authors: Caviedes-Cleves Mario Alberto , Arias Luis Fernando , Ospina-Ospina Sigifredo
Published: July 2022

Introducción. La lesión renal aguda (LRA) en el paciente con COVID-19 ocurre más frecuentemente en presencia de enfermedades crónicas como diabetes, obesidad, hipertensión arterial y enfermedad renal crónica previa, considerándose un fuerte predictor de resultados desfavorables y mortalidad. El propósito de este estudio fue describir las características histopatológicas en biopsias renales de pacientes hospitalizados por COVID-19, que experimentaron algún grado de daño renal durante su hospitalización. Metodología. Se incluyeron 30 pacientes mayores de 18 años, hospitalizados en diferentes centros de atención en Medellín, Colombia, con diagnóstico confirmado de COVID-19, sin antecedente de terapia de reemplazo renal, que durante la infección desarrollaron algún grado de daño renal, y que tuvieran estudio histopatológico de biopsia renal. Se analizaron las características demográficas, formas clínicas de presentación y hallazgos histopatológicos a nivel renal. Resultados. La mayoría de los pacientes eran de sexo masculino (70%). Los antecedentes patológicos más frecuentes fueron la enfermedad renal crónica previa (16,7%), diabetes mellitus (16,7%), trasplante renal (13,3%) y VIH (10%). El 35,7% de los pacientes no tenían ninguna comorbilidad subyacente. La manifestación clínica inicial más frecuente fue la LRA (56,7%). Algunos pacientes tuvieron más de una manifestación clínica inicial. El 100% de los pacientes evaluados tuvieron hallazgos histopatológicos renales, siendo la nefritis tubulointersticial aguda (40%) el más frecuente. Conclusión. Nuestro estudio no descarta una posible asociación del sexo masculino con peores desenlaces en la enfermedad COVID-19. La LRA fue el hallazgo clínico inicial más frecuente. Es posible que los hallazgos histopatológicos del presente estudio puedan ser consecuencia del daño directo a nivel tubulointersticial renal y la mala perfusión renal, dado el estado de choque por la tormenta inflamatoria, el empeoramiento de enfermedades preexistentes, o la superposición clínica con otras entidades. Sin embargo, son necesarios más estudios para dilucidar los mecanismos por los cuales se generan estas lesiones.

Published: July 2022

The Ottoman Empire experienced a golden age during the reign of Sultan Sulaiman Al-Qanuni (1494-1566 AD), but after his reign weakened due to advances in European science and technology, in the 18th century the Ottoman Turks tried to restore its glory. by Westernization known as the Reorganization of Turkey. While socio-religious at that time experienced a decline, more than that, dynamism, creativity, progressivity and freedom of thought also decreased. This study aims to explore the origins of the westernization movement in the history of the development of Islamic education in terms of socio-political, socio-religious and social education. It is hoped that a precise definition of the ideal Islamic education will be obtained that is in accordance with the times and always provides the latest benefits for modern times. This study uses a socio-historical approach, which seeks to uncover and analyze the transformation process of the Islamic education system from a traditional system to a modern system. As a result, it was found that the cause of the decline of Muslims was the thinking of the Turkish people who were shackled by fatalism.

The study examined the drivers of women participation in agricultural activities in Nigeria. A total of 636 women farmers were used for the study and data were collected through interview and questionnaire process. Descriptive statistics, Participation index and Ordered Logit regression were used to analyze the data. The results revealed that the mean age, household size, farming experience and farm size were 44 years, 8 members, 18 years and 3.1 ha respectively. The result also revealed that women farmers in Nigeria engaged themselves in agricultural activities such as crop farming, livestock farming, agricultural trading, poultry farming, horticultural farming and aquaculture farming. Result of the participation index revealed that women farmers were actively involved in agriculture with 49.06 % of the women with high level of participation. The regression analysis revealed that the positive drivers of women participation in agricultural activities were household size, marital status, level of education, farming experience, disposable income, extension service and membership of association. In the contrary, distance to farm is a negative driver of women participation in agricultural activities in the study area. In addition, inadequate financial opportunities and inadequate access to extension services were among the serious constraints that hindered women participation in agricultural activities.

Authors: Abdillah Jibriil Ahmad , Sueb Sueb
Published: July 2022

As the situation of the Covid-19 pandemic in Indonesia is gradually recovering, schools may reopen for limited face-to-face learning under particular measures during this transition period to the post-pandemic. This study aims to describe the implementation of blended learning and student motivation in secondary schools in limited face-to-face classes. This qualitative study collected the data through observation and questionnaires, involving two classes of junior high school students (N=70) of one urban public school in Sidoarjo, East Java, where blended learning was mandatory during the transition period. The results show a clear difference between the two modes; students who participated during the in-person learning session are more enthusiastic, engaged, and active during teaching and learning activities, while students who studied at home seemed quieter and less motivated to learn during the blended learning session. Students further considered blended learning as a way to increase their learning motivation. They were more interested in the subject and had an easier way to find material online. Furthermore, various types of activities such as group and pair work, collaborative learning, and individual learning can be used to increase students’ engagement and interests during communicative language practice. The extrinsic and intrinsic factors of students as learning drivers should be considered by the teacher before applying certain learning methods and learning approaches, especially for English learning after the pandemic.

Digital Organizational Culture: Contributions to a Definition and Future Challenges
Authors: Serpa Sandro , José Sá Maria , Ferreira Carlos Miguel
Published: July 2022

Digitalization is unstoppable and takes place in all domains of human life. One of the areas in which this digitalization has profound implications is organizations, understood as coordinated collective units open to the external environment and that are based on and justified by the fulfillment of purposes that would not otherwise be fulfilled, and that have an organizational culture as, generically, forms of thinking, feeling and acting that are characteristics of each specific organization. Through a focused look on contributions to the definition of the concept of digitalization and future challenges, this paper analyzes and discusses the shaping of the digital component in organizational culture, which materializes in a digital organizational culture. To fulfill this aim, a document search of papers was carried out in two comprehensive databases that focus on this topic that served as the basis for our argument. Digital organizational culture, as a product and a process, is shaped by indeterminacy and uncertainty, in an environment permeated by digital technology. However, it is already a reality that new technologies permeate all spheres of organizations and, therefore, organizations need to put in place a well-planned and well-defined strategy for this whole process of digital transition to accomplish this transformation successfully.

Financial Participation Among Smallholder - Farmers in Zimbabwe: What Are the Driving Factors?
Authors: Mhlanga David , Hassan Adewale Samuel
Published: July 2022

Small-scale farmers' financial participation boosts output while also raising living conditions by breaking the poverty cycle. Many policymakers regard it as a necessary input for increasing agricultural production because it is a vital aspect of the agriculture sector's commercialization and the modernization of the rural economy. Financial participation is a vital input for agriculture to achieve substantial growth. Small-scale farmers' financial engagement in many rural families remains a concern in Zimbabwe, despite the construction of a vast network of financial institutions in towns and growth centres. This research examines the factors that influence smallholder farmers' engagement in Zimbabwe's formal financial markets. The Binary Logit model was used to evaluate the characteristics that influence smallholder farmers' engagement informal financial markets. The results from the logit model indicated that “gender, household head age, land size, and agricultural extension service” were the significant factors influencing financial participation by smallholder farmers. As a result, the government should prioritize measures targeted at expanding the area of land available to small-scale farmers to ensure that these farmers are in the position to commercialise their activities. Again, support towards agricultural extension programs aimed at expanding farmer training and “doubling efforts to guarantee that the age distribution in farms” is balanced between the young and the old, as age has an impact on formal financial market involvement.

Authors:   Taegu Science University Defense Security Institute, Kim Nam Sook
Published: July 2022

The purpose of this study is to identify the status of appropriate community supporting systems through analysis of local government ordinances after deinstitutionalization of the disabled in the facility. To achieve this, Pusan government ordinance analysis was conducted. Since there is no deinstitutionalization support law, the existing ordinances related to deinstitutionalization of local governments are the basis. This is because macro-practice has a great influence on mezzo- and micro-practice. In this study, ordinances related to housing, lifelong education, communication support and human rights were analyzed as in the local independent living. Content analysis was used as the research method. As a framework for analysis, the composition of ordinances, rights and accountability, validity of the target scope, type and degree of benefits, financial responsibility, and securing of delivery system were used. In order to make a more active and persuasive argument, a comparative analysis was conducted with the ordinances related to deinstitutionalization in Seoul. Conclusions and recommendations are presented based on the analysis results.

Infection caused by Monkeypox Virus (MPVX) has small rodents as its natural reservoir and both monkeys and humans are occasional hosts. The causative agent is an Orthopoxvirus (MPVX) that was isolated in monkeys in 1958 and proved capable of passing to humans in 1970. It remained contained in Africa, causing isolated episodes of infection, until 2003 when an outbreak occurred in the United States following importation of animals from that continent. Since then, anecdotal cases have continued to be reported outside Africa, usually very clearly linked to travelers to those countries, but in May 2022, a broad outbreak of this disease has begun, now affecting several continents, with the emergence of human cases of MPVX (H-MPVX) infection mainly among Men that have Sex with Men (MSM). The disease has an incubation time ranging from 5 to 15 days and is characterized by the presence of pustules, fever, malaise and headache. The presence of significant regional lymphadenopathy is a differential feature with episodes of classical smallpox. Proctitis and pharyngitis, with minimal skin lesions, may be another form of presentation. Diagnosis can be confirmed by PCR testing of lesions or by demonstration of MPVX in other body fluids or tissues, although in the appropriate epidemiologic setting the clinical picture is highly suggestive of the disease. Effective drug treatment has been developed as part of programs to protect against potential bioterrorist agents and smallpox vaccinees are known to have high protection against monkeypox. New vaccines are available, but neither the drugs nor the vaccines are yet freely available on the market. The prognosis of the disease appears, at least in adults in developed countries, to be good, with very low mortality figures and much less aggressive behavior than that described in classical smallpox. Isolation measures, essential for the control of the outbreak, have been published by the health authorities.
POINT-RATING SYSTEM FOR ASSESSING THE KNOWLEDGE OF UNIVERSITY STUDENTS IN MATHEMATICS
Authors:   Samara State Transport University, Gumennikova Yu.V. , Kaidalova L.V. ,   Povolzhskiy State University of Telecommunications and Informatics, Zolkin A.L.
Published: July 2022

The article discusses various approaches to the definition of a point-rating system for evaluating educational achievements of students of higher education institutions, specifies the basic principles and main tasks of using BRS. Along with the advantages of such assessment systems, their disadvantages are also shown, the main of which is an increase in the time and complexity of control, leading to a significant increase in the load on the leading BRS teacher. Significant disadvantages are also the fact that many students with the introduction of the BRS assessment aim not so much to gain knowledge and competencies as to accumulate the greatest number of points. In order to mitigate these shortcomings and improve the BRS, it is recommended to leave at least 50% of the total number of points for intermediate certification; keep double records: the total score on the BRS and the score on the intermediate certification in the semester; ensure the possibility of redistributing points from one type of academic work to another. An example of the organization of the BRS assessment of the knowledge of bachelors in the field of "Construction" in mathematics, the use of which provides a weakening of these shortcomings, is given. The proposed model of the system of assessment of knowledge in mathematics can be recommended for use by teachers of higher educational institutions.

Published: July 2022

The presented article discusses the reasons for the low motivational activity of part-time trainees and the factors affecting the level of motivation. One of the ways to increase the level of motivation of part-time students by introducing tasks of professionally oriented content into the educational process is proposed. The authors propose to include professionally oriented tasks in test tasks in higher mathematics for students of distance learning in the specialty "Rolling stock of railways", specialization "Locomotives" of the Samara State Transport University. The article provides an example of professionally oriented tasks in higher mathematics for first-year students of correspondence courses. The proposed method of using tasks of professional content in the process of teaching part-time students has shown its effectiveness. The authors come to the conclusion that the use of professionally oriented mathematical problems in the process of distance learning of students of technical universities increases interest in studying the discipline, develops nonstandard thinking, and the desire to work independently. In addition, students accumulate mathematical knowledge that will be useful in their professional activities. The authors reserve the right, in the course of further research, to consider the application of tasks of professionally oriented content to other forms of education.
WHAT HAPPENED TO ONEGIN? POETICS OF ENDING IN PUSHKIN’S NOVEL IN VERSE
Authors:   GITR Film & Television School, Pimonov V.I.
Published: July 2022

Object of the article: the final scene of the novel in verse "Eugene Onegin" by A.S. Pushkin (ЕО, 8, XLVIII, 1-10). Subject of the article: the device of narrative interruption and poetics of the novel’s ending. Purpose of the research: analysis of the structure and meaning of the final scene. Results: the author argues that the interrupted narration in fact fully completes Onegin's storyline. The final scene contains: 1) the inversion of the binary oppositions "movement-immobility" / "living-dead", that is characteristic of the "sculptural myth"; 2) a foreshadowing of a possible duel between Onegin and Tatyana's husband. Field of application: literary criticism, teaching Russian literature of the 19th century. Conclusions: the probability of a duel between the general and Onegin is based on the symmetry and parallelism of the novel’s compositional design and a foreshadowing of the protagonist's death in a head-to-head combat. This duel is not implemented in the plot, but is virtually present in the semantic space of the novel. That virtual duel between two friends (8, XVIII) - Onegin and the general - is in inversely symmetric relation to the real duel between two friends — Onegin and Lensky. In the context of the revenge scheme, in which revenge for the murder is carried out by the double of the victim, Tatiana's husband plays a role of Lensky's "double" (in the function of "friend") who avenges his death.

Published: July 2022

If an adversary has unlimited computational power, then signer needs security against forgery. Fail Stop signature solves it. If the motive of the signature is to hide the identity of the signer who makes signature on behalf of the whole group then solution is Group signature. We combine these two features and propose “A new Fail Stop Group Signature scheme (FSGSS) over elliptic curves”. Security of our proposed FSGSS is based on “Elliptic curve discrete logarithm problem” (ECDLP). Use of elliptic curve makes our proposed FSGSS feasible to less bandwidth environment, Block chains etc. Due to security settings over elliptic curves, efficiency of proposed scheme increases in terms of computational complexity.

Published: July 2022

This paper presents a High Gain, enhanced Bandwidth Patch antenna for 5G operations. The dual-band is achieved using an inset-fed feeding technique for the microstrip patch antenna, which operates at the 28/38GHz millimeter-wave band. The high gain of the patch is achieved by inserting two rectangular slots on the radiating element of the patch. The designed antenna Bandwidth is improved by incorporating three steps at the edge of the rectangular patch. The substrate used for the format is Rogers RT Duroid 5880, with a thickness of 0.508mm, loss tangent of 0.0009, and a relative permittivity constant of 2.2. Ansys HFSS software is used for the simulation. The design attained a maximum gain of 8.2dB and 7.8dB at 27.84GHz and 39.32GHz. The impedance bandwidth response of 1.46 and 4.27GHz at the respective resonating frequencies below the -10dB line of the parameters are achieved. A compact antenna is proposed with a size of 3.2x4.9x0.508 and has a high Gain with a wide Bandwidth at both bands. The proposed antenna has achieved a good performance within the operating bands, making it suitable for 5G applications.

Published: July 2022

The LEA block encryption algorithm is an architecture suitable for IoT systems with limited resources and space. It was developed by the National Security Technology Research Institute in 2013 and established as an international standard for cryptography by the International Electrotechnical Commission in 2019, drawing much attention from developers. In this paper, the 128-bit LEA block encryption algorithm was light weighted and implemented in a hardware environment. All modules share and reuse registers and are designed and implemented in a bottom area through the resource sharing function. As a result of synthesis using Xilinx ISE 14.7 Virtex-5 as a design environment, the maximum frequency achieved 190.88 MHz and has a processing speed of up to 128 Mbps. Compared to the previously designed architecture, we present a bottom-level hardware design with a 128-bit LEA algorithm implemented with a 49.8% reduction in Flip-Flop, 18.8% reduction in LUTs, and 67.6% reduction in Slices.

The rise of digital technology has essentially enhanced the overall communication and data management system, facilitating essential medical care services. Considering this aspect, the healthcare system successfully managed patient requirements through online services and facilitated patient experience. However, the lack of adequate data security and increased digital activities during Covid-19 made the healthcare system a soft target for hackers to gain unauthorized access and steal crucial and sensitive information. Countries such as the UK and the US recently received such challenges, highlighting the need for effective data maintenance. IoT emerged as one of the critical solutions for data management systems in terms of addressing data security which certainly can enhance overall data collection, storage, maintenance, prediction of potential data security breaches and taking appropriate measurements. The concerned research considers a secondary data collection process where necessary data is collected from original scholarly articles, books and journals. Apart from that, a positivism research philosophy, a deductive research approach and a descriptive research design have been considered for this study. Qualitative data analysis techniques have also been incorporated into this research. Upon viewing the pros and cons of IoT algorithms, DES, AES, triple data encryption standards, and RSA encryption can be used in the healthcare system to facilitate data protection.

Implementation of Elliptical Curve Cryptography Based Diffie-Hellman Key Exchange Mechanism in Contiki Operating System for Internet of Things
Authors: Thapar Prateek , Batra Usha
Published: July 2022

Wireless Sensor Networks have gradually upgraded to Internet of Things (IoT) of embedded devices wherein the constrained devices have been connected directly onto the Internet. This transformation has not only facilitated the expansion in connectivity and accessibility of the sensor network but has also enabled one sensor network to interact with other through Internet. Security of IoT devices has been researched extensively. The challenge to transform the complex cryptographic algorithms into lighter and faster has kept researchers on their toes. Contiki-OS is one of the purest implementations of 6LoWPAN and IEEE 802.15.4. That makes Contiki-OS lightest and therefore preferred OS for implementation on ultra-low power sensor nodes. Elliptical Cryptography has proved to be the choice of most of the security researchers for constrained devices. However, there is very limited literature available on implementation of Elliptical Cryptography on Contiki-OS. The open-source libraries available for security implementation have not found to be supporting Cooja simulator of Contiki-OS. In this research work we demonstrate improved results in processing the Elliptical Cryptography Based implementation of Diffie-Hellman Key exchange mechanism in Contiki-OS using Cooja simulator. SECP160K1 curve has been implemented and the results in terms of ECDH computational time have been compared with previously published research works. This research demonstrates improved results in Cooja simulator than previous known results on hardware providing a leap ahead in efficiency of implementation.

Published: July 2022

This paper proposes a new maximum power point tracking (MPPT) technique for wind turbine Connection to a permanent magnet synchronous generator (PMSG), based on the Particle Swarm Optimization (PSO) algorithm. The PSO technique aims to control the boost converter by calculating the duty cycle value based on the voltage and current values. The Wind Energy Conversion System (WECS) includes a wind turbine, a PMSG, rectifier and a DC/DC boost converter that is connected to a load. To verify the performance of the suggested algorithm PSO, The results of the simulation are compared with those of fuzzy logic and (Perturb and Observe)P&O techniques, under step wind variations, using MATLAB/SIMULINK. The results of the simulation show that the proposed PSO technique ensures a good tracking of the maximum power point as the results obtained are more stable and the oscillations are eliminated.
