Authors: Souabi Sonia , Retbi Asmaâ , Khalidi Idrissi Mohammed Khalidi Idrissi , Bennani Samir
Published: December 2021

E-learning is renowned as one of the highly effective modalities of learning. Social learning, in turn, is considered to be of major importance as it promotes collaboration between learners. For properly managing learning resources, recommender systems have been implemented in e-learning to enhance learners' experience. Whilst recommender systems are of widespread concern in online learning, it is still unclear to educators how recommender systems can improve the learning process and have a positive impact on learning. This paper seeks to provide an overview of the recommender systems proposed in e-learning between 2007 and the first part of 2021. Out of 100 initially identified publications for the period between 2007 and the first part of 2021, 51 articles were included for final synthesis, according to specific criteria. The descriptive results show that most of the disciplines involved in educational recommender systems papers have approached e-learning in a general way without putting as much emphasis on social learning, and that recommender systems based on explicit feedbacks and ratings were the most frequently used in empirical studies. The synthesis of results presents several recommender systems types in e-learning: (1) Content-based recommender systems, (2) Collaborative-filtering recommender systems, (3) Hybrid recommender systems and (4) Recommender systems based on supervised and unsupervised algorithms. The conclusions reflect on the almost lack of critical reflection on the importance of addressing recommender systems in social learning and social educational networks in particular, especially as social learning has particular requirements, the weak databases size used in some research work, the importance of acknowledging the strengths and weaknesses of each type of recommender system in an educational context and the need for further exploration of implicit feedbacks more than explicit learners’ feedbacks for more accurate recommendations.
Examining Essential Flow Antecedents to promote students’ Self-Regulated Learning and Acceptance of Use in a Game-Based Learning classroom
Authors: Wan Kelvin , King Vivian , Chan Kevin
Published: December 2021

Game-Based Learning (GBL) has been recognized as an essential tool for motivating students to engage in active and constructive learning. While there is a link between GBL and learning outcomes, current research evidence tends to undermine the interrelationships of concepts and oversimplify flow experience in the context of GBL. This study used a comprehensive Flow perspective to examine the roles of specific gaming characteristics affecting students’ self-regulated learning and acceptances of use in a higher education GBL context, with a path model based on data collected from 275 undergraduate university students. The model demonstrated an excellent fit of the data with interrelations among constructs about Flow Antecedents, Acceptance of Use, Motivation and Metacognition. The findings revealed that learners place a higher value on GBL with flow elements like Concentration and Challenge, which is linked to their learning motivation and metacognitive outcomes. Aid by GBL on knowledge gain and immersive experience are considered as the underpinnings of Performance Expectancy before students consider adopting GBL for their learning. In contrast to what is typical of serious games, learners primarily use GBL to improve their academic performance rather than for its immersive experience.
The Influence of Convenience on the Usage of Learning Management System
Authors: Hussein Lubna A. , Hilmi Mohd Faiz
Published: December 2021

The advancement in internet-based learning technologies together with the national agenda towards globalized online education in Malaysia have prompted the learning management system (LMS) to become an important channel for institutions of higher education to effectively deliver education to students. Since user resistance has been known to be a stumbling block in the implementation of the LMS, it is crucial for the institutions to acknowledge that comprehensive adoption by users relies heavily on user acceptance. Moreover, since some institutions may have even made it compulsory for students to use the LMS, user acceptance of the LMS should be studied in the sense that using LMS is likable and pleasurable. Although the features of the technical capability of the LMS are important, it has been asserted that having the feeling of personal convenience when using the LMS is even more important to the users. With the amount of financial effort and manpower involved in implementing the LMS by institutions in Malaysia towards fulfilling the online learning agenda of the nation, it is important to study whether the convenience factor as an individual impact can play the partial role of influencing Malaysian students’ satisfaction of the LMS which would in turn influence them to use the LMS. Based on the Information System Success Model by DeLone and McLean, this study establishes vital process factors regarding the LMS usage among university students in Malaysia. Hence, in this study, LMS usage by students is measured by the degree of students’ acceptance of the LMS. An online survey has been done to collect data from 212 students of two large public universities in Malaysia. Structural equation modeling has been used to test the relationships in the conceptual model. The results of data analysis using the PLS-SEM technique employed in the study have indicated that student satisfaction is positively influenced by factors of information quality, system quality, service quality and convenience. LMS usage has been found to be positively impacted by student satisfaction while student satisfaction has been found to have significant mediation effect. The findings from this study can be utilized by institutions committed towards having successful implementation of the LMS. In enhancing LMS usage by the students, the institutions of higher education can consider focusing on the necessary steps towards increasing student satisfaction. Meanwhile, to increase student satisfaction, apart from improving the information quality, system quality and service quality, institutions should also seriously consider promoting the LMS to the students by highlighting the individual impact of the LMS in terms of convenience.

Authors: Zhuravlyova L.V. , Elhaj O.V.
Published: December 2021

The aim of the research was to study the relationship between plasma concentrations of resistin and indicators of enzyme and pigment metabolism in patients with non-alcoholic fatty liver disease (NAFLD) and its combination with type 2 diabetes mellitus (DM-2).

Materials and methods. On the base of Kharkiv Regional Hospital a total of 90 patients were examined, including patients with NAFLD (n = 20) and its combination with DM-2 with normal body weight (n = 20) and obesity (n = 50), as well as 20 healthy volunteers. A complex of clinical, laboratory and instrumental (including liver biopsy in 9 patients) examinations of patients was performed.

Results. A direct relationship was established between the level of resistin and indicators of enzyme and pigment exchange in groups of patients with combined pathology. A significant increase of resistin plasma level, as well as disorders of the liver function were determined in all groups of patients in comparison with the controls. The most marked changes were revealed in patients with combination of NAFLD, DM-2 and obesity.

Conclusions. The established relationship between the level of resistin and the indicators of the liver functional state suggests that an increase of resistin level may reflect the presence of impaired liver function in patients with NAFLD in combination with DM-2, predicting the progression of NAFLD. In order to detect the disorders of liver function in patients with DM-2, it is recommended to determine the level of resistin in patients with NAFLD, especially when concomitant obesity is present. Patients with resistin level (> 8.06 ± 0.23 ng/ml) should be considered at risk of NAFLD progression.

Authors: Zeynalov Yu. L.
Published: December 2021

Introduction Significant success has been achieved in the development of new methods of treatment and rehabilitation of patients with idiopathic scoliosis, however, in many aspects of this problem there is no unambiguous approach to the choice of a correction method, assessment of treatment results.

Objective To study the results of treatment of patients with idiopathic scoliosis according to X-ray and MSCT data, as well as according to the questionnaire – the SRS-30, depending on the degrees of the deformity, the type of scoliosis.

Material and methods The study is retrospective, single center. Evidence level – IV. In 300 patients with idiopathic scoliosis of varying severity at the age from 10 to 50 years, the immediate and long-term results of elimination of spinal deformity by the method of internal transpedicular fixation were studied. In the study we used polypositional radiography, multislice computed tomography (MSCT) and questionnaire SRS-30.

Results In patients with spinal deformity up to 60 ° a year after surgery, no loss of correction was found. After elimination of the deformity at 60–90 °, loss of correction up to 2 ° was observed in 3.6% of patients. In patients with deformity greater than 90 °, the average postoperative progression of scoliotic deformity was 3.5 ± 0.7 °. When examining patients after 2–5 years, there was no loss of correction in the group with initial spinal deformity up to 60 ° and in the group from 60–90 °. In patients with deformity greater than 90 °, the postoperative progression of scoliotic deformity in persons over 25 years old was 4.5 ± 0.6 °, which is associated with degenerative changes in the spine.

Conclusion The study of immediate and long-term results showed that 1 year after treatment, 94% of patients rated the treatment result as excellent and good, in 6% – as satisfactory. All patients noted a positive effect of the cosmetic and functional results of treatment, while 56% believed that they looked “better” than before surgery (4 points), 44% rated the effect at 5 points and noted that they looked “much better”. Long-term results were studied in 50 patients 10 years after surgery.

Published: December 2021

Природный дефицит водных ресурсов в сочетании с высокой степенью износа систем водоснабжения обусловливает напряженную ситуацию с обеспечением питьевой водой в Крыму. За последние несколько лет для решения проблемы на региональном и федеральном уровне были разработаны и реализуются программы модернизации водного хозяйства полуострова. Одной из ключевых задач этих программ является снижение потерь воды, которые в настоящее время достигают 40–60%. Описан комплекс мероприятий, направленных на снижение потерь воды в г. Севастополе. Комплекс мер, разработанный в соответствии с международным опытом и российскими рекомендациями, учитывает существующее состояние системы водоснабжения Крыма. Мероприятия включают в себя создание современного комплекса управления сетями, зонирование водопроводной сети, регулирование давления, мониторинг и устранение утечек. По результатам анализа производственных показателей определено, что первоочередным мероприятием для Севастополя является внедрение современной системы акустического мониторинга на распределительных сетях, которая позволит эффективно обнаруживать скрытые утечки и сэкономить городу тысячи кубометров дефицитной питьевой воды. Описаны результаты пилотного проекта по обследованию 5 км водопроводных сетей системой акустического мониторинга.

The natural scarcity of water resources coupled with a high degree of deterioration of water supply systems result in a tense situation with the drinking water supply in Crimea. Over the past few years, a number of programs of upgrading the peninsula's water industry have been developed and are being implemented in order to solve the problem at the regional and federal levels. One of the key objectives of these programs is to reduce water losses that currently reach 40–60%. A set of measures aimed at reducing water losses in Sebastopol is described. The set of measures developed in accordance with the international experience and Russian recommendations takes into account the current condition of the Crimean water supply system. The activities include designing an advanced network management complex, zoning of the water supply network, pressure regulation, monitoring and elimination of leaks. Based on the results of the analysis of the performance indicators, it was determined that the priority measure for Sebastopol was the introduction of an advanced acoustic monitoring system in the water distribution networks that would provide for detecting effectively latent leaks and saving the city thousands of cubic meters of scarce drinking water. The results of a pilot project on the inspection of 5 km of the water supply networks using the acoustic monitoring system are described.

Published: December 2021

Spectroscopic ellipsometry is a powerful tool for the characterization of thin films/surfaces. To simultaneously extract optical constant and film thickness from ellipsometric parameters ψ and Δ, dispersion models of material’s refractive index and spectroscopic ellipsometry measurement have been often required. In this work, we propose an extraction method of optical parameters of thin films from the reflection and transmission ellipsometric parameters. This method necessitates neither spectroscopic information of ψ and Δ, nor dispersion models. Verification measurements were carried out with the single-point and imaging ellipsometers, respectively.
Joint 3-D Positioning and Power Allocation for UAV Relay Aided by Geographic Information
Authors: Yi Pengfei , Zhu Liang , Zhu Lipeng , Xiao Zhenyu , Geng Xiangshuai
Published: December 2021

In this paper, we study to employ geographic information to address the blockage problem of air-to-ground links between UAV and terrestrial nodes. In particular, a UAV relay is deployed to establish communication links from a ground base station to multiple ground users. To improve communication capacity, we fifirst model the blockage effect caused by buildings according to the three-dimensional (3-D) geographic information. Then, an optimization problem is formulated to maximize the minimum capacity among users by jointly optimizing the 3-D position and power allocation of the UAV relay, under the constraints of link capacity, maximum transmit power, and blockage. To solve this complex non-convex problem, a two-loop optimization framework is developed based on Lagrangian relaxation. The outer-loop aims to obtain proper Lagrangian multipliers to ensure the solution of the Lagrangian problem converge to the tightest upper bound on the original problem. The inner-loop solves the Lagrangian problem by applying the block coordinate descent (BCD) and successive convex approximation (SCA) techniques, where UAV 3-D positioning and power allocation are alternately optimized in each iteration. Simulation results confifirm that the proposed solution signifificantly outperforms two benchmark schemes and achieves a performance close to the upper bound on the UAV relay system.

Early Stage Detection of Crack in Glasses by Hybrid CNN Transformation Approach
Authors: Kanthavel R.
Published: December 2021

Recently, glass crack detection methods have been emerging in Artificial intelligence programming. The early detection of the crack in glass could save many lives. Glass fractures can be detected automatically using machine vision. However, this has not been extensively researched. As a result, a detection algorithm is a benefit to study the mechanics of glass cracking. To test the algorithm, benchmark data are used and analysed. According to the first findings, the algorithm is capable of figuring out the screen more or less correctly and identifying the main fracture structures with sufficient efficiency required for majority of the applications. This research article has addressed the early detection of glass cracks by using edge detection, which delivers excellent accuracy in fracture identification. Following the pre-processing stage, the CNN technique extracts additional characteristics from the input pictures that have been provided due to dense feature extraction. The "Adam" optimizer is used to update the bias weights of networks in a cost-effective manner. Early identification is achievable with high accuracy metrics when using these approaches, as shown in the findings and discussion part of this paper.
Художня артикуляція проблеми постлюдства у п’єсі Карела Чапека “Р.У.Р. Россумові універсальні роботи”
Authors: Bondarewa Ołena , Bracki Artur
Published: December 2021

In the article Karel Čapek’s play “R.U.R. Rossum’s universal robots” is read not only as an anti-utopia devoted to the confrontation between humans and robots, but also as a work of art that defines a number of humanitarian discourses of the twentieth and early twenty-first centuries. The play correlates with modern humanitarian studies of posthumanity, posthumanism and transhumanism, examines various projects of posthumanistic reduplication of man – the archetype of the homunculus, types of humanized robots, cyborgs, iron warriors, predicts the decline of masculine discourse and the origins of feminism. The impact factor of this dramatic text goes beyond fiction and theatre and extends to the whole culture, because the concept of “robot” introduced by Karel Čapek is a stable concept of culture, transformation and technology. At the conceptual level, the article deals with the ability of artistic thinking to forecast, identify promising general scientific issues and structure future humanitarian discourses.

Multicentre clinical trial to evaluate microbial spectrum in acute diffuse otitis externa in the residents of Ukraine
Authors: Popovych Vasyl I.
Published: December 2021

Introduction: Acute diffuse otitis externa is a spread skin inflammation of the external ear canal of the bacterial origin. It is reported at an incidence of up to 10% among healthy population of all age groups. Treatment is known to be based on the empirical approach for prescribing topical antibacterials. Therefore studying the bacterial spectrum of otitis externa causative agents is of great value in terms of relevant antimicrobial therapy.
Aim: The objective of the study was to evaluate microbial spectrum in diffuse otitis externa in patients – residents of Ukraine.
Materials and methods: Four hundred and ninety-three out-patients diagnosed with acute diffuse otitis externa were enrolled. Microbial composition of the external ear canal microflora was tested and aetiologically relevant titres of colony-forming units (CFU) were determined. Criteria for evaluation: titres of 104 to 106 CFU and >106 CFU were considered aetiologically relevant. titres of <104 CFU were considered aetiologically nonrelevant.
Results and discussion: In the majority of cases of acute diffuse otitis externa, infection with Staphylococcus aureus in aetiologically relevant titres is reported in 53.2% and Pseudomonas aeruginosa in 23.6%. Cases of multimicrobial infection predominantly involving Gram-negative flora were also reported in 27.9%; each of them results in no more than 2 to 3% of otitis externa. Titres of Candida spp. (3.2%) and Staphylococcus epidermidis (2.6%) were measured as aetiologically non-relevant.
Conclusion: common microbial pathogens in acute diffuse otitis externa in patients of the Ukrainian population are Staphylococcus aureus and Pseudomonas aeruginosa. Multimicrobial associations predominantly involving Gram-negative flora, which do not exceed 2 to 3% of cases. Fungal infections are a rare cause of otitis externa.

The properties of PbMnS semiconductor thin films deposited on fluorine-doped tin oxide (FTO) substrate using an electrodeposition method are investigated to determine their possible device applications. Lead acetate, manganese sulfate, and thiourea were used as precursors for sources of lead, manganese, and sulfur ions respectively. The concentration of lead, manganese, and sulfur ions sources with deposition voltage of 1.8 V was kept constant. The films were deposited using three electrodes system of electrodeposition method by varying deposition time. The films were characterized for optical, structural, morphological, and compositional properties and results showed that the absorbance, refractive index, and optical conductivity of the films are high in the visible (VIS) and near-infrared (NIR) regions but decreases in the NIR. These three properties initially increased with an increase in deposition time up to a time of 70 s which has the highest values of these properties before decreasing to lower values. The transmittance and extinction coefficient of the films are low in both VIS and NIR regions. The bandgap energy of PbS was found to be blue shifted with values of 1.51 eV, 1.54 eV, 1.60 eV, 1.45 eV, and 1.35 eV for the films deposited at 30 s, 50 s, 70 s, 90 s, and 110 s respectively. XRD analysis showed that the films are crystalline with sharp peaks positions indexable to crystalline planes of (111), (200), (211), (220), (311) and (400) with average crystallite size in the range of 16.110 nm to 17.218 nm. Energy-dispersive X-ray spectroscopy (EDX) results showed that the films are composed of lead, manganese, and sulfur but there are some impurity elements present mostly as a result of the substrate used. These properties exhibited by the deposited thin films of PbMnS showed that they can be used for many optoelectronic applications such as photovoltaic cells, sensors, photoconductors, etc.

The testis is designated as one of the immune previleged sites in the body and harbours a unique immunoregulatory environment, which is important for preventing an immune response against sperm antigens which otherwise are recognized as “foreign” by the immune system. The blood-testis barrier along with the unique immune cells repertoire and various immunoregulatory & immunosuppressive factors secreted by the Leydig cells, Sertoli cells and peritubular cells act in concert to maintain the tolerogenic environment in the testis. Abberations in immunotolerant mechanisms in the testis can lead to generation of anti-sperm antibodies that have an association with male infertility. It can also lead to inflammatory conditions of the male reproductive tract manifested as epididymitis and orchitis, generally due to bacterial or viral infections. In addition, non-infectious epididymitis and orchitis, having autoimmune origin have also been reported in males. While the immune privilege status of human testis protects the germ cells from an immune attack, it can also make the testis a succeptible reservoir for viruses such as human immunodeficiency virus-1, Zika virus and severe acute respiratory syndrome coronavirus-2, all of which have adverse consequences on male reproduction.

Published: December 2021

The research efforts of this paper is to present a new inertial relaxed Tseng extrapolation method with weaker conditions for approximating the solution of a variational inequality problem, where the underlying operator is only required to be pseudomonotone. The strongly pseudomonotonicity and inverse strongly monotonicity assumptions which the existing literature used are successfully weakened. The strong convergence of the proposed method to a minimum-norm solution of a variational inequality problem are established. Furthermore, we present an application and some numerical experiments to show the efficiency and applicability of our method in comparison with other methods in the literature.

The UG-2 chromitite layer, with its elevated platinum-group element content, is a key marker horizon in the eastern and western limbs of the Bushveld Igneous Complex and the largest platinum-group element chromite-hosted resource of its kind in the world. In contrast, much less is known about its stratigraphic equivalent in the northern limb, the “UG-2 equivalent” (UG-2E) chromitite. Recent studies on chromite mineral chemistry show similarities between the UG-2 and sections of the UG-2E, but also that the UG-2E was partially contaminated by assimilation of local metasedimentary rocks. Here, we provide a detailed characterization of sulfide minerals and platinum-group minerals in a suite of samples from the UG-2E and compare the results with data obtained from a reference suite of samples from the UG-2. Results from petrographic observations, electron probe microanalysis, laser ablation-inductively coupled plasma-mass spectrometry, quantitative evaluation of materials by scanning electron microscopy, and δ34S isotopes show that: (1) sulfide minerals in the UG-2E and UG-2 consist mainly of pentlandite-chalcopyrite-pyrrhotite, but pyrrhotite is significantly more abundant in the UG-2E and almost absent in the UG-2; (2) iron contents in pentlandite from the UG-2E are significantly higher than in the UG-2; (3) platinum-group element contents within sulfide minerals are different between the two chromitites; (4) UG-2E platinum-group minerals are dominated by arsenides and bismuthotellurides, and by alloys and platinum-group element-sulfide minerals in the UG-2; (5) sulfide mineral chemistry and δ34S values indicate some crustal contamination of the UG-2E; and (6) sulfide mineral and secondary silicate mineral textures in both the UG-2E and UG-2 are indicative of minor, millimeter- to centimeter-scale, hydrothermal alteration. From our observations and results, we consider the UG-2E chromitite in the northern limb to be the equivalent to the UG-2 in the eastern and western limbs that has been contaminated by assimilation of Transvaal Supergroup footwall rocks during emplacement. The contamination resulted in UG-2E sulfide mineral elemental contents and platinum-group mineral types and abundances that are distinct from those of the UG-2 in the rest of the Bushveld.
End-to-end qualification of ready-to-use (RTU) product containers in packaging suitable for No-Touch Transfer (NTT) into Grade A filling zones

No-Touch Transfer (NTT) of pre-sterilised ready-to-use (RTU) containers is an alternative methodology that follows Good Manufacturing Practice (GMP) and Quality Risk Management (QRM) principles. NTT de-bagging ejects contents from secondary bag packaging without direct contact with contents or exposure to an environment that is a lower grade than the zone being entered. The pre-sterilised containers and sterile barriers offer assured sterility at manufacture and are qualified to remain sterile through the supply chain and the stepwise NTT de-bagging process. This eliminates the requirement for in-process material disinfection steps for transfer into Grade A environments.

The present article focuses on design qualification of pre-sterilised RTU container packaging, including definition of sterile barriers together with bioburden study data through the supply chain and simulated NTT. It completes a series of EJPPS articles to support peer-reviewed references on NTT. Together, these articles can be defined as end-to-end qualification of the NTT process, demonstrating a high level of assurance that sterility is maintained from manufacture to point of use.

Published: December 2021

Interplanetary coronal mass ejection (ICME) shocks are known to accelerate particles and contribute significantly to solar energetic particle events. We have performed magnetohydrodynamic-particle in cell simulations of ICME shocks to understand the acceleration mechanism. These shocks vary in Alfvénic Mach numbers as well as in magnetic field orientations (parallel and quasi-perpendicular). We find that diffusive shock acceleration plays a significant role in accelerating particles in a parallel ICME shock. In contrast, shock drift acceleration (SDA) plays a pivotal role in a quasi-perpendicular shock. High-Mach shocks are seen to accelerate particles more efficiently. Our simulations suggest that background turbulence and local particle velocity distribution around the shock can indirectly hint at the acceleration mechanism. Our results also point toward a few possible in situ observations that could validate our understanding of the topic.
