Published: August 2022

The Covid-19 pandemic has affected almost every aspect of life in the world, including education. The learning process, which was originally done face-to-face at school is diverted to the home using the online learning model. The inequality of the teacher's ability to utilize technology affects the achievement of this online learning goal. The ability of teachers to conduct online learning depends on knowledge and experience in online teaching before the Covid-19 pandemic. Objective: This study was conducted to expose information related to teachers’ experience toward online learning before the Covid-19 pandemic. Method: The study was carried out by implementing a descriptive quantitative method. The instrument used in this study was questionnaires distributed online using the Google Form application. The data were analyzed through the stages of data reduction, data interpretation, and conclusion drawing. Finding: The results showed that 75% of teachers stated that they already had basic knowledge about online learning before the Covid-19 pandemic. 45.80% of teachers said they obtained information about online learning through school-facilitated training while 16.70% gathered information about online learning before the Covid-19 pandemic from government-facilitated training, and 37.50% obtained information about online learning from independent learning. A total of 54.10% of teachers stated had conducted online learning before the Covid-19 pandemic. However, only 20.80% of them stated that online learning is very effective to be implemented. Conclusion: The readiness of teachers to implement online teaching-learning depends on their knowledge and experience related to online learning. Inadequate teaching training causes the lack of understanding of teachers towards the benefits of supported information technology-based learning media.

Authors: Harendita Monica Ella , Kristianto Ignatius Indra
Published: August 2022

The COVID-19 pandemic has resulted in disruptions in a number of aspects of our lives, including in language education. Teaching and learning are now done remotely using various online learning platforms and educational technologies. While one of the foci in 21st-century skills is collaboration, how to design and manage group work in online courses remains a challenge for language educators. The Community of Inquiry (CoI) framework, which consists of teaching presence, cognitive presence, and social presence, has been widely employed in designing an effective online course. Thus, through online questionnaires and interviews, this descriptive qualitative research explored the experiences of seven university lecturers from two private universities in Jogjakarta to know how teaching presence was realized in coping with online group work. The results show how the participants have implemented a variety of facilitation strategies to maintain student engagement through different modes of communication, learning models, progress monitoring, and peer feedback. This research is also expected to shed a light on the challenges and strategies taken by lecturers to ensure that collaboration occurs in their classes.

Clustering is a technique for grouping homogeneous data so that the points in each cluster are as similar as possible according to convenience measures such as Euclidean-based distance or correlation-based distance. In the industrial era 4.0, learning media, the environment, the way teachers teach will affect student learning styles. From research on learning styles, many researchers agree on the importance of identifying learning styles to accelerate their learning performance. The purpose of this study is to classify student learning styles in the industrial era 4.0 using the Kmeans algorithm and the elbow method. The research method used is a waterfall. The number of research subjects was 108 students. the results of the research on the number of clusters (K), namely 6, obtained cluster 1 as many as 27 students, cluster 2 as many as 24 students, cluster 3 as many as 21 students, cluster 4 as many as 17 students, cluster 5 as many as 11 students and cluster 6 as many as 8 students. The performance of the grouping results based on the silhouette coefficient is 0.302, which means the grouping structure is weak. In cluster 1, the highest number has auditory elements, followed by kinesthetic and visual elements. The development of ICT-based media is one of the factors of student learning styles in the industrial era 4.0

Published: August 2022

—Based on the analysis of the petrographic and lithogeochemical features of the Middle Jurassic–Lower Cretaceous strata in the lower reaches of the Anabar River, we have studied the regularities of changes in the composition of the upper parts of the Yuryung-Tumus and Sodiemykha formations and the lower part of the Buolkalakh Formation. It has been established that the silt–sandy rocks of the first and basal beds of the second formation are graywacke arkoses and essentially feldspathic varieties, and most of the Sodiemykha Formation is composed of quartz–feldspathic and scarcer feldspar–quartz graywackes. A chemical classification of the rocks was made; most of them were assigned to normosiallites. The rocks of the marker beds, namely, the Fe-containing deposits of the Sodiemykha Formation, the basal glauconite bed of the Buolkalakh Formation, and the overlying clay bed, were classified as hypohydrolysates. All the studied deposits are of low sedimentary maturity, with essentially petrogenic clastic material. These are predominantly igneous rocks of intermediate and, less, felsic composition. The provenances were characterized by moderate chemical weathering. In the periods of the formation of the marker beds, chemical weathering intensified, and the amount of mafic and, partly, ultramafic rocks increased. The established changes in the composition of the parental strata are observed in the Middle Jurassic–Lower Cretaceous deposits of the entire considered petromineralogical province, which permits them to be used for correlation.

Published: August 2022

—We present new data on the chemical composition of the late Precambrian rocks in the upper part of the regional Balaganakh stratigraphic horizon (the Nugan Formation at the Baikal segment of the Sayan–Baikal–Patom belt (SBPB) and the Bugarikhta Formation of the Balaganakh Group at the Patom segment of the SBPB) and the U–Pb (LA-ICP-MS) age of detrital zircons from the Bugarikhta Formation. It has been established that the rocks of the Nugan and Bugarikhta formations resulted from the destruction of igneous and metamorphic rocks. The contents and ratios of trace and rare-earth elements in the rocks of the Nugan and Bugarikhta formations indicate a predominance of felsic igneous rocks in the provenance and the presence of rocks of mafic and intermediate compositions at the source of the terrigenous rocks of the Nugan Formation. The U–Pb age of detrital zircons from all rocks of the upper part of the regional Balaganakh Horizon is close to the age of the rocks in the basement of the southern margin of the Siberian Platform, which suggests that this basement was the main source of clastic material in the sedimentation basins. It is argued that the “pre-glacial” (pre-Marinoan) terrigenous deposits of the Nugan and Bugarikhta formations, as well as the deposits of the Ipsit Formation at the Sayan segment of the SBPB, accumulated in the Late Riphean (ca. 720–640 Ma), probably in postrift basins that formed immediately after the separation of Siberia from Laurentia at the early stages of the opening of the Paleoasian Ocean.
Deep-Learning-Based Noniterative 2D-Inversion of Unfocused Lateral Logs
Authors: Danilovskiy K.N. , Petrov A.M. , Asanov O.O. , Sukhorukova K.V.
Published: August 2022

—The work deals with the development of methodological and algorithmic tools for the quantitative interpretation of oil well resistivity logs. We review the results of applying the neural-network-based approach to the inversion of resistivity logs measured at thinly bedded high-contrast environments. The capabilities of the proposed approach are demonstrated by the example of the algorithm for noninterative express inversion of unfocused lateral logs (BKZ). BKZ is the unfocused array logging method widely used in the Commonwealth of Independent States for oil well studies. BKZ logs are known for their complexity: The signals of unfocused gradient probes are highly affected by the medium properties below and above the measuring point. The developed algorithm is based on the inversion of full logs into the parameters of a 2D axisymmetric model of the medium, which allows naturally taking into account the influence of surrounding rocks and borehole conditions. Transition from the “layered” parametrization conventional for BKZ logs interpretation to a quasi-continuous change of properties along the well axis allows extracting meaningful information at every measurement point and constructing high-resolution geoelectric models of the sediments. The noniterative nature of the algorithm provides a high computing efficiency. This opens up the possibility of using the 2D inversion advantages to increase the reliability of the initial express interpretation results. Testing the algorithm on the practical data from West Siberian oilfields has revealed the field of its maximum efficiency, namely, study of impermeable and low-permeability sediments, such as the complex shaly caprocks and bituminous deposits of the Bazhenov Formation. With high-quality input data, the approach is also efficient for studying permeable terrigenous sediments.
Distribution of Hydrocarbon Resources by Fields of Different Sizes and by the Number of Pools in Each Field
Authors: Livshits V.R. , Kontorovich A.E.
Published: August 2022

—This study describes a procedure for estimating the distribution of hydrocarbon resources by fields with different sizes of reserves and by the number of pools in each field. Such an evaluation is important in predicting the efficiency of exploration. The procedure first uses a simulation model for generating a population of hydrocarbon pool sizes. Then the spatial distribution of pools over a petroleum basin is modeled as a nonstationary Poisson point field. When we generate a field population in the basin, each field is considered a geometric object consisting of several pools according to the principle of their mutual geometric location. The proposed model was used to estimate a two-dimensional distribution of the number of fields and resources contained in them by resource sizes and the number of pools in each field. The proposed assessment was made for oil resources in the West Siberian petroleum province.

Published: August 2022

The Denitrification-Decomposition (DNDC)-Rice is a mechanistic model which is widely used for the simulation and estimation of greenhouse gas emissions [nitrous oxide (N2O)] from soils under rice cultivation. N2O emissions from paddy fields in South Korea are of high importance for their cumulative effect on climate. The objective of this study was to estimate the N2O emissions and biogeochemical factors involved in N2O emissions such as ammonium (NH4+) and nitrate (NO3−) using the DNDC model in the rice-growing regions of South Korea. N2O emission was observed at every application of fertilizer and during end-season drainage at different rice-growing regions in South Korea. Maximum NH4+ and NO3− were observed at 0–10 cm depth of soil. NH4+ increased at each fertilizer application and no change in NO3− was observed during flooding. NH4+ decreased and NO3− increased simultaneously at end-season drainage. Minimum and maximum cumulative N2O emissions were observed at Chungcheongbuk-do and Jeju-do regions of South Korea, respectively. The simulated average cumulative N2O emission in rice paddies of South Korea was 1.37 kg N2O-N ha−1 season−1. This study will help in calculating the total nitrogen emissions from agriculture land of South Korea and the World.

Published: August 2022

Background:

The bioactive constituents from Zingiber officinale (Z. officinale) have shown
a positive effect on neurodegenerative diseases like Alzheimer's disease (AD), which manifests as
progressive memory loss and cognitive impairment.

Objective:

This study investigates the binding ability and the pharmaco-therapeutic potential of Z. officinale
with AD disease targets by molecular docking and molecular dynamic (MD) simulation approaches.

Method:

By coupling enormous available phytochemical data and advanced computational technologies,
the possible molecular mechanism of action of these bioactive compounds was deciphered by
evaluating phytochemicals, target fishing, and network biological analysis.

Results:

As a result, 175 bioactive compounds and 264 human target proteins were identified. The
gene ontology and Kyoto Encyclopaedia of Genes and Genomes pathway enrichment analysis and
molecular docking were used to predict the basis of vital bioactive compounds and biomolecular
mechanisms involved in the treatment of AD. Amongst selected bioactive compounds, 10-
Gingerdione and 1-dehydro-[8]-gingerdione exhibited significant anti-neurological properties against
AD targeting amyloid precursor protein with docking energy of -6.0 and -5.6, respectively.

Conclusion:

This study suggests that 10-Gingerdione and 1-dehydro-[8]-gingerdione strongly modulates
the anti-neurological activity and are associated with pathological features like amyloid-β
plaques and hyperphosphorylated tau protein are found to be critically regulated by these two target
proteins. This comprehensive analysis provides a clue for further investigation of these natural compounds'
inhibitory activity in drug discovery for AD treatment.
Nudge on Choice Architecture: Effectiveness of Economic Recovery Policy and Irrational Behavior Predictions
Authors: Rahmawati Titi
Published: August 2022

Economic recovery policy in low-income communities is a priority of the government in tackling the tidal wave of the economy during the COVID-19 pandemic. This study aims to map the government's priorities and rapid action in its careful planning also implementation. The challenge is how society has a drive about a wide range of choices that have many possibilities, namely maximizing added value to the aid or fulfilling desires that approach irrational behavior. Therefore, encouragement is needed by every individual to choose choices that are in line with the government's policy objectives to eliminate or eliminate extreme poverty. The method used is an analysis of social science and behavioral science with circumplex strategy, which is further analyzed in correlation with quantitative methods using Kendall W. Test analysis and continued double regression. The results showed that encouragement had a positive and insignificant influence on the effectiveness of BLT policies; predictions of irrational behavior have a negative and insignificant influence on the effectiveness of BLT policies; And together, nudge and irrational predictably have a positive and significant influence on the effectiveness of Top Up BLT policies. Recommendations on the encouragement in improving the architecture of choice are the collaboration between the program implementation team and related stakeholders; irrational behavior predictions are anticipating irrational behavior tendencies by understanding the vulnerability of preconditions and conditions in the implementation of the program; the maintenance of the commitment of the central and local government and village government in enforcing regulations.

The results of numerical simulation based on the Mie theory of the effect of superresonance (high-order Fano resonance) for a mesoscale dielectric sphere immersed in air are presented, since the environment in the form of a vacuum is an idealization that is almost never realized in nature. Using the example of a particle with a refractive index of 1.5 and a size parameter q~ 26 and q~ 38, it was demonstrated for the first time that a change in the refractive index of the environment by 2.4 10^-4 leads to a decrease in the field intensity in the region of the shadow pole of the sphere by an order of magnitude and a shift of the resonant value of the size parameter q to the short-wavelength region. In this case, the relative intensities of the resonant peaks for both the magnetic and electric fields in the vicinity of the poles of the sphere in the optical range can reach values ​​characteristic of a particle in vacuum (of the order of 10^6–10^7), with an appropriate adjustment of the resonant size parameter.

Efficacy and Conflicts of Interest in Randomized Controlled Trials Evaluating Headspace and Calm Apps: Systematic Review
Authors: O'Daffer Alison , Colt Susannah F , Wasil Akash R , Lau Nancy
Published: August 2022

Background

Although there are thousands of mental health apps, 2 apps, Headspace and Calm, claim a large percentage of the marketplace. These two mindfulness and meditation apps have reached tens of millions of active users. To guide consumers, clinicians, and researchers, we performed a systematic review of randomized controlled trials (RCTs) of Headspace and Calm.

Objective

Our study aimed to evaluate intervention efficacy, risk of bias, and conflicts of interest (COIs) in the evidence base for Headspace and Calm, the two most popular mental health apps at the time of our search.

Methods

To identify studies, we searched academic databases (Google Scholar, MEDLINE, and PsycINFO) and the websites of Headspace and Calm in May 2021 for RCTs of Headspace and Calm testing efficacy via original data collection, published in English in peer-reviewed journals. For each study, we coded (1) study characteristics (eg, participants, sample size, and outcome measures), (2) intervention characteristics (eg, free vs paid version of the app and intended frequency of app usage), (3) all study outcomes, (4) Cochrane risk of bias variables, and (5) COI variables (eg, presence or absence of a preregistration and the presence or absence of a COI statement involving the company).

Results

We identified 14 RCTs of Headspace and 1 RCT of Calm. Overall, 93% (13/14) of RCTs of Headspace and 100% (1/1) of RCTs of Calm recruited participants from a nonclinical population. Studies commonly measured mindfulness, well-being, stress, depressive symptoms, and anxiety symptoms. Headspace use improved depression in 75% of studies that evaluated it as an outcome. Findings were mixed for mindfulness, well-being, stress, and anxiety, but at least 40% of studies showed improvement for each of these outcomes. Studies were generally underpowered to detect “small” or “medium” effect sizes. Furthermore, 50% (7/14) of RCTs of Headspace and 0% (0/1) of RCTs of Calm reported a COI that involved Headspace or Calm (the companies). The most common COI was the app company providing premium app access for free for participants, and notably, 14% (2/14) of RCTs of Headspace reported Headspace employee involvement in study design, execution, and data analysis. Only 36% (5/14) of RCTs of Headspace were preregistered, and the 1 RCT of Calm was not preregistered.

Conclusions

The empirical research on Headspace appears promising, whereas there is an absence of randomized trials on Calm. Limitations of this study include an inability to compare Headspace and Calm owing to the dearth of RCTs studying Calm and the reliance on author reports to evaluate COIs. When determining whether or not mental health apps are of high quality, identification of high-quality apps and evaluation of their effectiveness and investigators’ COIs should be ensured.
Conjugate properties of Pi3/Ps6 pulsations according to Antarctica-Greenland observations
Authors: Martines-Bedenko Valery , Pilipenko Vyacheslav , Hartinger Mike , Partamies Noora , Pilipenko V
Published: August 2022

We consider interhemispheric properties of fine structure of substorm – quasi-periodic geomagnetic fluctuations, Pi3 pulsations, using data from conjugate magnetometers in Antarctica and Greenland. Pi3 pulsations are found to accompany both the substorm expansion/recovery phases and the steady magnetospheric convection (SMC) events. The epicenter of Pi3 power is at the same latitude as maximal amplitude of magnetic bays. The interhemispheric properties of Pi3 pulsations are not consistent: in some events, coherent in-phase magnetic oscillations are observed in both hemispheres, in others, periodic variations are observed in one hemisphere only. When Pi3 pulsations are observed in both conjugate sites, their H-components are in-phase, which corresponds to the fundamental mode of field line oscillations between high-conductive ionospheres. Conjugate observations have provided an additional information on an elusive mechanism of Pi3 pulsations.

Published: August 2022

Like elsewhere around the globe, SARS-CoV-2 infection is spreading in rural Egypt. Due to high sensitivity and specificity, the gold standard of diagnostics is reverse transcription polymerase chain reaction PCR (RT-PCR). Rural areas without access to certified laboratories cannot take advantage of RT-PCR testing, and thus are dependent upon rapid antigen testing, a point-of-care test that requires less training and can produce results within 15 minutes. Rapid antigen testing can give an advantage to medical teams in rural settings by affording effective and early control of SARS-CoV-2 infection spread. We sought to assess the contribution of different COVID-19 testing procedures in rural Egypt. We conducted a prospective cohort study in a rural lab in Giza, Egypt. Approximately 223 individuals with potential SARS-CoV-2 infection were involved in the study during the pandemic peak in Giza, Egypt, from March 4 – May 30, 2021. Subjects were subjected to RT-PCR and rapid antigen testing, and the performance of each testing procedure was compared. Between March 4 – May 30, 2021, approximately 223 symptomatic individuals were included in this study. 190 patients (85.2%) were indicated as PCR positive for SARS-CoV-2, while 33 (14.8%) were PCR negative. In comparison, a rapid antigen test showed 178 out of 223 patients (79.8%) were indicated as positive, or 94% of the PCR-positive individuals. In Giza, a rural area of Egypt, RT-PCR had an optimal balance of sensitivity and specificity, however, the turnaround time was a limiting factor. Antigen testing, performed as a rapid point-of-care test, can play an effective role in rural outbreak control due to its ease of use and rapid results.

Comparative Study on Seismic Behavior of High–Rise Steel Building with and Without Friction Damper and Fluid Viscous Damper: A Review
Authors: Madgounkar Sachin Sunil , S Naveen Kumar H , K Chethan Gowda R
Published: August 2022

Abstract: Seismic forces are induced on the structure present in earthquake prone areas. These are induced due to the movement of tectonic plates. Multi-storey buildings are those that have more than two stories, hence undergo large amount of deflection due to their slender structure. Due to the deflection caused by the ground accelerations during earthquakes, the structure is unstable and the structure undergoes damage which is not safe. Passive energy dissipation devices are gaining significance in design of earthquake resistant structures because of their effective performance in controlling seismic effects on structures during earthquake. Friction dampers and fluid viscous damper are passive energy dissipating devices which are used widely as seismic control devices. The present study was conducted analytically on a 15-storey steel frame with regular and irregular configuration and performance of structure against non-linear time history ground movement with and without friction damper and fluid viscous damper. Time history ground acceleration data of Bhuj earthquake (2001) were applied on the structure and the response of friction damper and fluid viscous damper was analyzed and compared. The analysis of the structure for the non-linear dynamic ground acceleration was conducted using ETABS software. The results show that when a friction damper is used instead of a fluid viscus damper, storey displacement is greatly reduced by 25.52%. whereas results shows that storey shear, storey drift, and storey acceleration are greatly reduced by 27.75%, 30.39% and 15.27%, when fluid viscous damper is used instead of a friction damper.

Abstract: Earthquakes are the indication for transformation of earth internal surface. The Indian subcontinent has suffered some of the greatest earthquakes in the world. Many research studies have been focusing on decreasing the impact of seismic waves on structures. For this initially there were many passive techniques introduced to reduce the damage caused due to earthquakes which are based on decreasing the lateral loads on structures. But since the late twentieth century the focus has shifted to introduce active earthquake techniques which are meant to absorb the seismic waves or do not let the waves propagate through the building. Though it is not possible to prevent an earthquake, the least that can be achieved in reducing the damage is to make the buildings earthquake resistant with the advancements in earthquake resistant techniques. The major goal of this dissertation is to use CABKOMA strands to create a novel earthquake-resistant technology. In this study, CABKOMA strands are used to examine the seismic response of ordinary moment resisting steel framed structures of high rise, mid-rise, and low rise analyzed with and without strands to determine the workability of cabkoma strands. To determine how well the intended structures function against earthquake motions, a comparative examination is done between them. Additionally, this work shows a comparative analysis of the seismic behavior of high-rise, mid-rise, and low-rise steel structures designed utilizing CABKOMA strands with the seismic behavior of high-rise steel structures designed using bracings an existing earthquake technique, by varying the arrangement of strands at the corner, Centre, and both centre and edge of the structures. Eventually, this work presents cabkoma strand optimization for effective strand utilization by varying strand to strand spacing from 0.5m to 1m while maintaining the same strand positioning.

Abstract: In this modern age, the general crime rate is increasing day-by-day and to cope up with this the enforcement departments too should find ways in which would speed up the overall process and help them in bringing one to justice. One such way can be using face recognition technology for identifying and verifying the criminal. The traditional approach here is to use the hand-drawn face sketches drawn by forensic sketch artist tospot the criminal, modernizing this is able to mean using the hand-drawn sketch and then matching them with the enforcement departments database to spot the criminal. Using this approach would result in the various limitations with latest technologies andeven would be time consuming as there are very few forensic sketch artists available when compared to the increasing crime ratio. Our project is aimed on decreasing the time span and speeding up this process by providing a standalone platform to the law enforcement department which would allow users to create accurate face sketch of the suspect without the help of forensic sketch artist and no special training or artistic skills. The sketch can be created using drag and drop feature in the application with variety of face elements and can automatically match the drawn composite face sketch with the law enforcement departments database much faster and efficiently using deep learning and cloud infrastructure.

Abstract: Many mobile platforms have developed as a result of the development of mobile technology. Rapid technological advancement has led to the widespread adoption of mobile devices with excellent graphics. Since its inception, the Open Handset Alliance project known as Android has undergone numerous revisions. Being centred on efficiency and pace, it's development. Android OS is driven by the Dalvik microkernel. The Android OS is sluggish due to the runtime as it is a virtual system. Android's multitasking capability leads to its latency. Earlier, there have been efforts to speed up Dalvik, but they were inefficacious. Increasing Android's speed and optimization was severely hampered by this. The Android Runtime (ART), which takes the role of the Dalvik Virtual Machine, made its debut when Android 4.4 was released by Google. A fast gadget was made possible by ART, which skillfully blends portability and performance, which eventually enhanced graphics optimization. A pre-compiled program was maintained for the Android applications by ART, which was not feasible with Dalvik Virtual machine. A speed of double has been observed on the Android Operating system, in several experiments. This paper discloses the architecture of android virtual machines (Dalvik and ART), memory optimization and efficiency of both in various devices. Also lists out the for and against of the latter one over the former and the basic functions of the runtimes
