Authors: Espinosa Torres David Felipe , González Bejarano Iván Camilo , Moreno Restrepo Juliana
Published: August 2021

Feedback is a powerful tool that has a significant influence on student success. Its meaningful impact on learning and teaching processes has been well-documented. However, there is minimal research concerning the impact of feedback strategies on foreign language learning. This article seeks to provide a theoretical and practical understanding of the impact of feedback on foreign language teaching and learning processes. This is done through a case study research conducted in a private institution in Bogotá, Colombia. The evidence demonstrates that the feedback strategies used and the manner in which they are administered influence their effectiveness. Three main strategies were observed and analyzed: corrective, motivational, and developmental. This article concludes with a suggestion to make feedback an explicit policy of teachers’ education programs in the country.

Authors: Peñaloza Anna Carolina , Rallón Ana Olga
Published: August 2021

The following case study describes and interprets pen pal letter exchanges between medical students and rural elementary school students. This study was carried out with three third and fourth semester medical students at a public university in Tunja, Colombia. In addition, we also worked with a group of five elementary school girls from a rural community located 20 minutes from the university. Both groups participated in exchanging pen pal letters in English as a way to foster the sociocultural competence in communication. In order to analyze the communication established between the participants, we used students’ artifacts, field notes, and reflective discussions. The findings revealed that the students’ fostered authentic communication based on the language they wanted to convey. As the communication between the students developed, instances of affiliates, advice giving, imitation, modeling, and empathy appeared. The pen pal letters showed that both groups are in a crucial period of identity construction, for which pen pal letters can help empower students and model positive behavior.

Nicotine Neurotoxicity Involves Low Wnt1 Signaling in Spinal Locomotor Networks of the Postnatal Rodent Spinal Cord
Authors: Kaur Jaspreet , Mazzone Graciela L. , Aquino Jorge B. , Nistri Andrea
Published: August 2021

The postnatal rodent spinal cord in-vitro is a useful model to investigate early pathophysiological changes after injury. While low dose nicotine (1µM) induces neuroprotection, how higher doses affect spinal networks is unknown. Using spinal preparations of postnatal wild-type Wistar rat and Wnt1Cre2:Rosa26Tom double-transgenic mouse, we studied the effect of nicotine (0.5-10µM) on locomotor networks in-vitro. Nicotine 10µM induced motoneuron depolarization, suppressed monosynaptic reflexes, and decreased fictive locomotion in rat spinal cord. Delayed fall in neuronal numbers (including motoneurons) of central and ventral regions emerged without loss of dorsal neurons. Conversely, nicotine (0.5-1µM) preserved neurons throughout the spinal cord and strongly activated the Wnt1 signaling pathway. High-dose nicotine enhanced expression of S100 and GFAP in astrocytes suggesting their response to stress. Excitotoxicity induced by kainate was contrasted by nicotine (10µM) in the dorsal area and persisted in central and ventral regions with no change basal Wnt signaling. When combining nicotine with kainate, the activation of Wnt1 was reduced compared to kainate/sham. The present results suggest that high dose nicotine was neurotoxic to central and ventral spinal neurons as the neuroprotective role of Wnt signaling became attenuated. This also corroborates the risk of cigarette smoking for the foetus/newborn since tobacco contains nicotine.
Computational Analysis of Haemodynamic Indices in Synthetic Atherosclerotic Coronary Netwroks
Authors: Simakov Sergey , Gamilov Timur , Kopylov Philipp , Liang Fuyou
Published: August 2021

Haemodynamic indices are widely used in clinical practice for deciding on a particular type of treatment. Low quality of the CT data and tachycardia complicate interpretation of the measured or simulated values. In this work, we present a novel approach for evaluating resistances in terminal coronary arteries. Using 14 measurements from 10 patients, we show that this algorithm retains the accuracy of 1D haemodynamic simulations in less detailed (truncated) geometric models of coronary networks. We also apply the variable systole fraction model to study the effect of elevated heart rate on the values of FFR, CFR and iFR. We conclude that tachycardia may produce both overestimation or underestimation of coronary stenosis significance.
Tangent Based-Path Path Planning with Distinctive Topologies in a Dynamic Environment
Authors: Yao Zhuo
Published: August 2021

This manuscript proposes a novel tangent-graph-based method that provides all distinctive topology paths, as a set of trajectories that can not be transformed into each other by gradual bending and stretching without colliding with obstacles. As the global optimal trajectory (limited by dynamic constraints) may not correspond to the shortest path (almost without dynamic constraints), it is important to provide all distinctive topology paths rather than just the globally shortest one. One of the application is provide initial paths for trajectory planning methods, such as time elastic band (TEB) and dynamic window approach (DWA). Considering that a mobile platform is always working in a dynamic changing environment and that update the whole graph is time consuming, a dynamic rectify method is proposed to update tangents according to local map provided by sensor reading. Finally, results under real grid maps are presented.
Integrating Emerging Technologies into Higher Education – The Future Perceptions
Authors: Leoste Janika , Jõgi Larissa , Õun Tiia , Pastor Luis , San Martín López José , Grauberg Indrek
Published: August 2021

Emerging technologies have a potential future impact on the developments in higher education and teaching practices at the universities. The paper is based on the project “My future colleague robot” that aims to improve the competence of university teachers in the implementation of Emerging Technologies (ETs) in the teaching practices at the university. In this paper, we identified the strengths and weaknesses, opportunities and threats that are related to the adoption of two ETs, robotics and Artificial Intelligence (AI), in higher education. Additionally, we analyzed the perceptions of faculty about these ETs. The empirical data was collected using written essays from 18 university teachers and students. Deductive and inductive approaches with thematic analysis were used for the data analysis. The findings support the idea that previous experience related to ETs can support positive attitudes and the implementations of ET in university teaching. University teachers had optimistic expectations towards ETs accepting them as part of teaching practice development, while discussion about the negative effects of ETs was negligible.
Soft and Hard Iron Compensation for the Compasses of an Operational Towed Hydrophone Array without Sensor Motion by a Helmholtz Coil
Authors: Lapucci Tommaso , Troiano Luigi , Carobbi Carlo , Capineri Lorenzo
Published: August 2021

Usually, towed hydrophone arrays are instrumented with a set of compasses. Data from these sensors are utilized while beamforming the acoustic signal for target bearing estimation. However, elements of the hydrophone array mounted in the neighborhood of a compass can affect the Earth’s magnetic field detection. The effects depend upon the kind of elements present in the platform hosting the compass. If the disturbances are constant in time, they can be compensated for by means of a magnetic calibration. This process is commonly known as soft and hard iron compensation. In this paper, a solution is presented to carry out the magnetic calibration of a COTS (Commercial Off The Shelf) digital compass without unattainable sensor motion. This approach is particularly suited in applications where a physical rotation of the platform that hosts the sensor is unfeasible. In our case, the platform consists in an assembled and operational towed hydrophone array. A standard calibration process relies on physical rotation of the platform and thus on the use of the geomagnetic field as a reference during the compensation. As a variation on this approach, we provide to the sensor an artificial reference magnetic field to simulate the unfeasible physical rotation. We obtain this by using a tri-axial Helmholtz coil, which enables programmability of the reference magnetic field and assures the required field uniformity. In our work, the simulated geomagnetic field is characterized in terms of its uncertainty. The analysis indicates that our method and experimental set-up represent a suitably accurate approach for the soft and hard iron compensation of the compasses equipped in the hydrophone array under test.

Authors: Ortega Ana Lucía , Kingsley-Thomas Diana , Suarez Paula
Published: August 2021

A project-based module on Sustainable Development Goal number 5, Gender Equality, was im-plemented on 5 different groups of Business English students consisting of a total number of 62 students in higher education. The main purpose of this project was to raise awareness of this goal by means of a flipped method in which students were required to carry out some research on specific areas of the aforementioned goal and work in teams to elaborate oral presentations. Once their findings were shared in class, students were expected to answer a written questionnaire of open-ended questions which were part of a qualitative analysis. Results of this survey showed that not only 90% of the students gained in depth knowledge of this goal, but also 85% had built a positive attitude to take initiative and 80% were optimistic about future gender equality. Finally, 70% of students suggested further social action to curb the problem of gender discrimination. On the whole, the flipped classroom method of learning combined with project-based group work have proven to be an effective way to raise awareness of this goal, create a more positive attitude, in-crease their willingness to take action as well as widening their English lexical resources.
3D Geophysical Post-Inversion Feature Extraction for Mineral Exploration Through Fast-ICA
Authors: Abbassi Bahman , Cheng Li Zhen
Published: August 2021

A major problem in the post-inversion geophysical interpretation is the extraction of geological information from inverted physical property models, which do not necessarily represent all underlying geological features. No matter how accurate the inversions are, each inverted physical property model is sensitive to limited aspects of subsurface geology and is insensitive to other geological features that are otherwise detectable with complementary physical property models. Therefore, specific parts of the geological model can be reconstructed from different physical property models. To show how this reconstruction works, we simulated a complex geological system that comprises an original layered earth model that has passed several geological deformations and alteration overprints. Linear combination of complex geological features comprised three physical property distributions: Electrical resistivity, induced polarization chargeability, and magnetic susceptibility models. This study proposes a multivariate feature extraction approach to extract information about the underlying geological features comprising the bulk physical properties. We evaluated our method in numerical simulations and compared three feature extraction algorithms to see the tolerance of each method to the geological artifacts and noises. We show that the fast-independent component analysis (fast-ICA) algorithm by negentropy maximization is a robust method in the geological feature extraction that can handle the added unknown geological noises. The post-inversion physical properties are also used to reconstruct the underlying geological sources. We show that the sharpness of the inverted images is an important constraint on the feature extraction process. Our method successfully separates geological features in multiple 3D physical property models. This methodology is reproducible for any number of lithologies and physical property combinations and can recover the latent geological features, including the background geological patterns from overprints of chemical alteration.
Qualitative Parameter Analysis for Botrytis cinerea Forecast Modelling Using IoT Sensor Networks

Published: August 2021

This paper presents the evaluation of a fungal disease forecast model in vineyards for qualitative parameter analysis using the data from off the shelf sensors, i.e. temperature and air relative humidity, rain precipitation, and leaf wetness. The rules for the fungal disease models are digitalized as a decision support tool that serve as an indicator to farmers for the need of spraying of the chemical substances to ensure the best growing condition and suppress the level of parasites. The temperature and humidity contexts are used interchangeably in practice to detect the risk of the disease occurrence. By taking into account a number of influences on these parameters collected from the shelf sensors, new topics for research in the multidimensional field of precision agriculture emerge. In this study, the impact of the humidity is evaluated by assessing how different humidity parameters correlate with the accuracy of the Botrytis cinerea fungi forecast. Each humidity parameter has it’s own threshold that triggers the second step of the disease modeling - risk index based on the temperature. The research showed that for humidity a low-cost relative humidity sensor can detect in average 14.61% risk values, a leaf wetness sensor an additional 3.99% risk cases, and finally, a precipitation sensor will detect only an additional 0.59% risk cases.

Published: August 2021

Changes in land use in the Cikapundung watershed, ie changes in forest land to built-up land, have an impact on the quantity of river water. Changes in land use in the Cikapundung River catchment are not ideal conditions for absorbing water. If land conversion is not controlled, it can have a large impact on reducing the availability of water resources for subordinate areas or what is called water scarcity. Analysis that takes into account land use and discharge can be done with several hydrological analysis methods, one of them is the Soil Conservation Service Curve Number (SCS-CN) method. Based on the calculation, the CN value was changed in 2014 from 57.275 to 62.591 where land cover changes began to occur.

The survey shows that the community's ability to utilize Islamic financial products is still low. This fact contradicts the potential development of a halal lifestyle and the increasing number of middle-class Muslims, and the fact that 87.2% of Indonesians are Muslim. It turns out that not many people know and take advantage of Islamic financial products, including Islamic investment. The purpose of the study was to determine the factors behind investment behaviour in sharia instruments as a form of implementing the halal lifestyle of people in Indonesia. The research subjects are Muslims who have or are currently investing in sharia securities, with 100 respondents. Data were collected by distributing online questionnaires. The data analysis technique uses Partial Least Square. The results show that attitudes and perceived behavioural control affect intention in investing in sharia securities, while subjective norms do not affect. Investment intention in sharia securities affects investment decisions. This study proves that investors' assessments and perceptions of factors that can support their investment activities, such as knowledge and skills, can influence their interest in investing in the Islamic capital market. Thus, it is essential to conduct training for novice investors to provide exposure to the Islamic capital market.

Financing risk is a condition of uncertainty that affects the success of a business to gain profit. Meanwhile, basic earning power is the ability to generate profits based on the capital owned. This study analyzes the risk and basic earning power of financing in the tapioca agro-industry using an interest-free calculation basis. The data used are primary data from field observations at the center of tapioca agro-industry in Ciluar, Bogor Regency, and secondary data from literature studies. The analysis is carried out by calculating the risk of loss and profitability of financing using the assumption of an acceptance rate of 10% of the total capital and when the level of acceptance falls -10% of the total capital owned. Furthermore, a comparison is made between tapioca agro-industries that use an interest-bearing financing scheme, including variables of risk of loss, income level, and profitability level. The research results prove that the bigger the loan used, the greater the risk to be borne. Another finding is that interest-free financing in the tapioca agro-industry has a higher return and income rate than interest-bearing financing.

The KNN method is used for disease classification based on the distance between training data and test data, while F-Score feature selection is used to reduce the attribute dimensions in order to obtain the relevant attributes. The data set used was data on cattle disease in Madura with a total of 350 data consisting of 21 features and 7 classes. Data were broken down using K-fold Cross Validation using k = 5. Based on the test results, the best accuracy was obtained with the number of features = 18 and KNN (k = 3) which resulted in an accuracy of 94.28571, a recall of 0.942857 and a precision of 0.942857.

The need for information systems is increasing every year. The information system of an organization or company is useful for managing data to produce useful and effective information that supports activities and all levels of management that use it. The aspect of software quality is one of the important things in the development of a software. To determine the quality of software products, a measurement is needed. IBSI Education, one of which is a Tutoring Institution that uses “SiWeSi” to support administration, view schedules, see student progress, and so on. The success of the software that is built is based on whether or not the software works according to the objectives to be achieved. In the scientific concept of software engineering, the success of software is not only seen from the suitability of the resulting product to existing needs. The success of the software is also seen from the software development process. This study uses the McCall quality model because this method fulfills many components of the assessment and looks at quality from the user's point of view. The quality model used to measure the quality of SIWESI is determined from the results of the literature study.

Background

Since 2020, the COVID-19 pandemic spread worldwide causing health, economic, and social distresses. Containment strategy relay on rapid and consistent methodology for molecular detection and characterization. The emerging variants of concern (VOCs) are currently associated with increased infectivity, and immune escape (natural defense mechanisms as well as a vaccine). Several VOCs has been detected and include lineage B.1.1.7 first identified in the UK, linage B.1.351 in South Africa, and lineage P.1 (B.1.1.28.1) in Brazil. Here we validated a rapid and low-cost technique to distinguish B.1.1.7, B.1.351 and P.1 SARS-CoV-2 variants by detecting Spike gene mutations using RT-PCR methodology.
Results

We recruited 77 positive patients affected by Coronavirus Disease-19 (COVID-19). Specific Real-time reverse transcription-polymerase chain reaction (RT-PCR) was employed targeting single nucleotide polymorphisms (SNPs) to screen Spike protein mutations. All data were validated by next generation sequencing (NGS) methodology and using sequence from a public database.Among 77 COVID-19 positive samples we could discriminate with 100% of concordance all the investigated SARS-CoV-2 variants when comparing with NGS method.
Conclusions

PCR-based assays for identification of circulating VOCs of SARS-CoV-2 resulted in a rapid method to identify the specific SARS-CoV-2 variants allowing a better survey of the spread of the virus and its transmissibility in the pandemic phase.

The aim of this research is to study the comparative wear behaviour of pure Al2O3 with varying TiO2 content due to the high demand in the industry for high temperature applications such as the automotive industry (piston ring and liner), petrochemicals industry (pump sleeves) and textile industry tools which require the hard bearing surface, abrasion resistance and particle corrosion at the temperature of up to 400 °C. In the present study, three coatings of Al2O3, Al2O3-13%(TiO2) and Al2O3-40%(TiO2) composite coatings were deposited by the thermally flame spray process. The comparative wear behaviour of the Al2O3-TiO2 coatings has been studied under high temperature of up to 400°C using a high temperature tribometer at a constant load of 40N. Before the wear test, the mechanical properties of the coated samples such as microhardness and surface roughness were studied. The morphological analysis was determined by field emission scanning electron microscope, elemental dispersion spectroscopy and X-ray powder diffraction techniques. The results reveal that specific wear rate decreases with a rise in temperature for all the deposited coating except Al2O3 coating at 400°C. The friction coefficient of deposited three alumina based coatings is decreasing with the increasing temperature. The research reveals that the Al2O3-40%TiO2 coating has the highest wear resistance properties as well as a low coefficient of friction due to its low hardness and high adhesion properties. For Al2O3-40%TiO2 coating the measured values of specific wear rate varying from 0.034567*10-3 mm3/Nm to 0.014581*10-3 mm3/Nm and the average values of coefficient friction ranging from 0.7284 to 0.3901 as temperature varying from room temperature to 400°C. In the worn out surface of deposited coatings, brittle fracture and abrasive wear behaviour were observed from room temperature to 400°C.

Development of geothermal power plants and local geothermal energy initiatives have lagged due to the social problems such as conflicts with stakeholders such as Onsen (Hot Spa) owners, despite the abundant geothermal resources. Study area was Tsuchiyu Onsen in Fukushima prefecture, Tohoku (Northeast) District, Japan, where the Great East Japan Earthquake and Fukushima Nuclear Accident occurred in 2011, and the reconstruction and local initiatives of geothermal energy were still unclear. Agent-based modeling (ABM) is an effective methodology for modeling and analysis of opinion formation. Parameter estimation method was proposed to extract appropriate parameters from various factors through a Bayesian Network. The characteristics of stakeholders and communities that affected opinion formation in the survey area were successfully extracted. Here we show the sufficient methodology to quantify the characteristics of each person using survey data, and to extract the parameters of the agent by data-driven inverse analysis. By using this methodology, we could reproduce opinion diversity, which is a property of opinion formation in real communities. This result suggests that the model replicates the actual formation of opinion in Tsuchiyu, where the economy was boosted by the construction of a binary cycle power plant.

Objective This study compared the government policies and non-pharmaceutical interventions adopted by South Korea, Japan, India, and China in response to COVID-19 during 2020-2021. We hope that our study would propose policies for future COVID-19 waves and provide lessons for future responses to similar infectious diseases.Methods We made a retrospective study by analyzing the government policies and non-pharmaceutical interventions in these four countries. We utilized policy information and non-pharmaceutical intervention measures from governmental web pages, WHO publications, scientific articles, and conventional media. We summarized the measures implemented in each of these four Asian countries, and assessed the effectiveness of the prevention and control measures.Results From January 2020 to May 18, 2021, South Korea and Japan experienced three waves of COVID-19 epidemic, but the number of daily new confirmed cases per million people was relatively small in both countries, and South Korea had fewer daily new confirmed cases per million than Japan. Following the COVID-19 outbreak in Wuhan in late 2019, China successfully contained the first wave of the outbreak and is not currently experiencing a large-scale resurgence of the epidemic. India is experiencing a grim second wave of the epidemic, with far more daily new confirmed cases per million people than South Korea and Japan. Throughout 2020, the number of COVID-19 deaths per million population remains low in South Korea, Japan, and China, while India has seen an upward trend in deaths per million population since July. As of May 18, 2021, the number of total tests per thousand people in South Korea, India, and Japan was 230.65, 181.23, and 99.59, respectively. South Korea and India both have more than twice as total tests per thousand people as Japan.Conclusion Successful practices in China and South Korea show that--case identification and management, coupled with close contact tracing and isolation, is a powerful strategy. The lessons of Japan and India show that social distancing is an effective measure, but only if it is rigor and persistent. Finally, in both developed and developing countries, the development of health care systems and coordinated government leadership play a key role in overcoming epidemics.

Published: August 2021

The impacts of Co nanoparticles (NPs) on the anaerobic digestion (AD) of cow dung were investigated using kinetic models (modified Gompertze, logistic, and first-order) and experimental measurements. The deviation between the predicted and measured data for biogas yield with modified Gompertze and logistic models were (0.66%-2.26%) and (1.43%-4.19%), respectively. The addition of Co NPs (1-3 mg/L) improved the hydrolysis rate (K) value by (66.66%-144%) compared with the control. Furthermore, effluent with Co NPs showed remarkable fertility (4.63%-5.32%). The combination of kinetic models and experimental measurements can effectively quantify the impact of Co NPs on AD performance and provide an informed choice for industrial production.
