Authors: Ferrag Mohamed Amine , Friha Othmane , Hamouda Djallel , Maglaras Leandros , Janicke Helge
Published: January 2022

In this paper, we propose a new comprehensive realistic cyber security dataset of IoT and IIoT applications, called Edge-IIoTset, which can be used by machine learning-based intrusion detection systems in two different modes, namely, centralized and federated learning. Specifically, the proposed testbed is organized into seven layers, including, Cloud Computing Layer, Network Functions Virtualization Layer, Blockchain Network Layer, Fog Computing Layer, Software-Defined Networking Layer, Edge Computing Layer, and IoT and IIoT Perception Layer. In each layer, we use new emerging technologies that satisfy the key requirements of IoT and IIoT applications, such as, ThingsBoard IoT platform, OPNFV platform, Hyperledger Sawtooth, Digital twin, ONOS SDN controller, Mosquitto MQTT brokers, Modbus TCP/IP, ...etc. The IoT data are generated from various IoT devices (more than 10 types) such as Low-cost digital sensors for sensing temperature and humidity, Ultrasonic sensor, Water level detection sensor, pH Sensor Meter, Soil Moisture sensor, Heart Rate Sensor, Flame Sensor, ...etc.). Furthermore, we identify and analyze fourteen attacks related to IoT and IIoT connectivity protocols, which are categorized into five threats, including, DoS/DDoS attacks, Information gathering, Man in the middle attacks, Injection attacks, and Malware attacks. In addition, we extract features obtained from different sources, including alerts, system resources, logs, network traffic, and propose new 61 features with high correlations from 1176 found features. After processing and analyzing the proposed realistic cyber security dataset, we provide a primary exploratory data analysis and evaluate the performance of machine learning approaches (i.e., traditional machine learning as well as deep learning) in both centralized and federated learning modes.

Published: January 2022

Related to the first period of the COVID-19 pandemic (March-June 2020), some recent studies on the application of content analysis of geolocalized tweets (Bashar et alii 2020, Punziano et alii 2020) have demonstrated the negative relation between the Coronavirus spread (with Northern Italy most affected) and the polarity of social narratives about the pandemic. In brief, the «resilient» social narrative of the most impacted regions has corresponded to a negative and worried emergency narrative of the less affected regions. In relation to epidemiological data, the second phase of the pandemic (also referred to as the «second wave», in autumn 2020) has been very different from the first (ISSa 2020). The severity of emergency, without considering questions about the reliability of the first wave data (Istat 2020a), has been more relevant and homogeneous across Italy. The study questions whether there are differences between the geography of contagion and that of the narrative. Given the increasingly homogeneous spread of the virus, the assumption has been that the digital arena also has ended up showing a narrative more united on negative sentiments. The issue is addressed by analyzing a corpus of geolocalized tweets, extracted in the period from the new October lockdown to the partial and fragmented pre-Christmas reopenings in 2020. Following the application of a model combining text mining and GIS analysis, the most recurrent themes in social discourse on Twitter were mapped. This geography of emerging social narratives (COVID-Issues) compared with the geography of contagion spread (COVID-Spread) and the norms (COVID-Measures) allowed to detect the trend in the relationship of these three dimensions during the second emergence from COVID-19.

Authors: Fathurohman  , Sayuti Muhamad , Lambas T Alexander
Published: January 2022

Scheduling is the allocation of limited resources to do a number of jobs. Problems arise when at certain stages of operation some or all of the work requires the same work station. PT XYZ is a service company engaged in electro plating, where the work process is carried out when receiving a request from the customer. The arrival of products from customers who are late and other things will affect the process of working on the products to be plated so that the schedule for sending back products that have been platted is not on schedule while the company does not have inventory. Therefore, a good production machine scheduling optimization will be able to produce good processing time. In addition to knowing the number of machines and jobs as well as the number and sequence of their production processes, research is also carried out by calculating the processing time of each job. Based on the comparison between the best iterations of CDS and the company's FSCS method, it is known that there is a difference in makespan time of 46990 seconds or about 13.05 hours and a flowtime difference of 216380 seconds or about 60.1 hours.

Sensing the occurrence and dynamics of Cercospora leaf spot disease using UAV-supported image data and deep learning
Authors: Ispizua Yamati Facundo R. , Barreto Abel , Günder Maurice , Bauckhage Christian , Mahlein Anne-Katrin
Published: January 2022

The most damaging foliar disease in sugar beet is Cercospora leaf spot (CLS), caused by Cercospora beticola Sacc. The pathogen is expanding its territory due to climate conditions, generating the need for early and accurate detection to avoid yield losses. In Germany, monitoring and control strategies are based on visual field assessments, with the parameter disease incidence (DI). This parameter triggers warning systems when a threshold is achieved, and decision-making takes place for fungicide application. However, visual scoring is a time-consuming activity that requires well-trained personnel and is the principal bottleneck for CLS control. Digital technologies can support this process. Thus, the present work is based on two trial fields conducted and monitored in 2020 using an unmanned aerial vehicle (UAV) equipped with a multispectral camera. Image data were collected in time series during the vegetation period. Trials were sown with different sugar beet varieties; for field management, there was employed diverse fungicide strategies, and artificial inoculation took place in a spot manner. Parallel to the flight mission and additional assessment of DI, disease severity (DS) via KWS scale was collected by experts as so-called ground truth (GT). Combined with image-processing, it was possible to catalogize plants in field trials, identify them over time, and use them for training and testing models. A convolutional neural network (CNN) supported by cataloged data was trained to perform classification of the disease presence in time-series, and performance was evaluated. As the last image processing step, maps were generated showing site-specific distribution of the diseased plants in the field. Generated maps can serve as a basis for application maps in practical cultivation or the evaluation of variety performance in variety trials. The presented methodological approach provides high precision and sensitivity in CLS detection and offers the potential to automate processes of CLS monitoring for different application areas.

Com ele objetivamos apresentar as narrativas de docentes da Educação de Jovens e Adultos (EJA) das escolas públicas municipais de Sobral como potenciais instrumentos de captação de sentidos de currículos em Matemática. Para isso, trazemos narrativas de dois docentes, em que destacam sobre como constroem suas práticas curriculares. Dentre os resultados, a verificação de que esses docentes elaboram suas práticas tendo os conteúdos escolares como referências, mas, prezam pelo respeito das especificidades dos estudantes. Entendemos, assim, que eles constroem seus próprios currículos com sentidos ligados às aprendizagens das vivências dos estudantes, bem como prezando pelo respeito às diferenças que constituem esses sujeitos, em detrimento de um currículo como grade de conteúdos e engessador de suas ações em sala de aula. Concluímos destacando que a ação de ouvir os docentes da EJA pode contribuir para tornar mais perceptíveis os sentidos de currículos em Matemática.

Authors: Rahman Rio Aulia , Chudari Ima Ni’mah
Published: January 2022

Due to the rampant Covid-19 virus, education is also getting its impact. Teaching and learning activities that are usually carried out in schools have turned into learning from home (BDR) programs. There are new problems faced by students when faced with the BDR program. Guidance and counseling services are assistance programs aimed at students or individuals so that they can overcome the problems they face. Based on research conducted on 6th grade teachers and students, 5th grade teachers and students, 3rd grade teachers and students at SDN 1 Sumurbandung, it was shown that obstacles were found while the teacher provided guidance and counseling services during the BDR program.  The research conducted is a qualitative research with a case study method (case study). Data collection techniques used are interviews and documentation studies. Interviews were conducted online using Google Meet or Zoom Meeting media. Based on the data obtained, the teacher provides guidance and counseling services virtually (online) and in person (visiting students' homes). Some of the obstacles faced by teachers were signal problems, many children were found who did not have gadgets, did not have quotas, and excessive parental assistance. Ways that teachers do to overcome these obstacles include providing motivation, communicating with students' parents, doing remedial actions, providing relief from task collection time and providing policies for students who do not have online learning facilities.

Authors: Cuji Cristian , Mediavilla Ernesto
Published: January 2022

El presente artículo considera un escenario de transición a fuentes energía renovable no convencional (ERNC) de tecnología mixta, compuesta por generación solar fotovoltaica y micro generación eólica, tomando en cuenta un evento paulatino de descarbonización. Como caso de estudio se va considerar la central termoeléctrica Dayuma (2MW), ubicada en la provincia de Orellana, Ecuador. Inicialmente para su desarrollo se evaluó los recursos naturales energéticos de la zona, tales como, temperatura, irradiancia, velocidad de viento en sus puntos máximos, mínimos y promedio, en un intervalo de tiempo de cinco años. Posteriormente para la óptima gestión de la producción energética se utilizó controladores basados en lógica difusa, para el seguimiento del punto de máxima potencia (MPPT), y se ha comparado este controlador con un P&O convencional. Finalmente se llevó a cabo los cálculos correspondientes para determinar la cantidad de paneles de alta eficiencia necesarios y se comparó con otros de baja, de igual forma se estableció el número de micro-generadores eólicos y el área física necesaria para la implementación de la central propuesta en cada uno de los casos, obteniendo resultados importantes para la posibilidad de la sustitución de la central termoeléctrica existente. Con esta investigación se busca estimar la máxima generación posible mediante la obtención del punto de máxima transferencia de potencia basado en un control lógico difuso y con esto definir la posibilidad de suplantar la central térmica ya mencionada.

A continuación, se presentan los resultados del estudio de estimación de los costos de energía eléctrica, obtenidos mediante resultados de laboratorio y corroborados por la simulación de la energía generada a base de hidrógeno, para revisar la factibilidad en el ámbito económico dentro del consumo doméstico de energía eléctrica. Para ello, se realizó el análisis energético del hidrógeno en el mercado, mediante el factor de recuperación (EPBT) el cual nos da como resultado que debe pasar 1.62 años para que una celda de hidrogeno compense la energía que utilizo. De los resultados obtenidos en laboratorio y del modelo matemático en el cual se utilizó una celda de combustible tipo PEM con 46% de eficiencia para que genere 24V, se puede observar la cantidad de energía que se necesita para producir electricidad y el costo de la energía que se produce, la cual es analizada desde el punto de vista energético, técnico y económico, obteniendo así las fortalezas de ser una energía limpia libre de contaminación ya que su único residuo es vapor de agua, pero con la gran desventaja que en el ámbito eléctrico  se producen mayores pérdidas de energía debido a la baja eficiencia de las celdas de combustible.
ALELOPATHIC SENSITIVITY OF OILSEED RADISH TO THE MAIN SPECIES OF WEEDS AT THE STAGE OF LABORATORY GROWTH
Authors: Tsytsiura Yaroslav , Inna Tsaruk
Published: January 2022

The article summarizes the importance of studying alelopathic interactions between plants, taking into consideration the ecologization and biologization of the weed control system in agrocenoses of agricultural crops. The urgency in solving this issue with the use of intermediate forage and green manure crops and, in particular, oil radish, has been emphasized. The paper presents the results of studying the efficiency of using oil radish as a phyto-mediator in crop rotation to suppress and control various biological weed species by determining the germination of seeds of the oil-bearing radish variety Zhuravka by two research methods – germination on filter paper when moistened with water extracts of various types of weeds and germination on soil subtrate when moistened with the same extracts in a mode close to real soil conditions for germination of oil radish seeds.
The used wide range of concentration of aqueous extracts from 0.25% to 16.0% with equal interval step allowed us to confirm the significantly different sensitivity of oil radish at the germination stage both in the version of traditional germination on filter paper and in germination on a soil substrate. At the same time, it was noted that oil radish has a sensitive reaction to water extracts of the studied 20 species of weed plants in the concentration range from 0.25% to 16% with the boundary value of the formation of the minimum level of laboratory seed germination at a concentration of 4.0%. The maximum effect of the impact on the indicators of laboratory germination of oil radish seeds, taking into consideration the minimum permissible level of decrease in the value of germination of seeds, was noted in the concentration range of aqueous extracts of 1.0-4.0%.
Gradual growth of allelopathic pressure on germination of oil radish seeds on filter paper can be placed in such an increasing row: Field mustard (PA) - Artemisia ragweed (PA) - Tenacious ragweed (PA) - Wild radish (PA) - Actinoid thistle (PA) - Lettuce wild (PA) - Wheatgrass (PA) - Field cabbage (VA) - Common shchiritsa (VA) - Rough highlander (VA) - Field bindweed (VA) - Kulbuba officinalis (VA) - Field horsetail (VA) - Golinsoga small-flowered ( VA) - Common herringbone (VA) - Gray bristle grass (VA) - Canadian malignant (VA) - Yellow thistle (VA) - Pink thistle (VA) - White Mary (VA).

Exploring the Link Between the Psychological Needs and the Elements of Game Design for Educational Games
Authors: Chin Ike Tan , Wee Hoe Tan
Published: January 2022

This paper explores the link between play, an evolutionary and biological trait found in human behaviour and the fundamental human psychological needs; and its complex relationship with the game design principles in order to answer the following - why do people play games and what motivates them to do so? Answering these two questions would enable educational game designers to better understand game design principles for developing engaging educational games. This research will delve into the psychological aspects of play and attempt to link those aspects to game design elements. Studying Prensky’s six elements of successful games, the Octalysis gamification framework and the fundamental psychological needs, the paper will then present the findings of an exploratory and confirmatory survey from practicing game designers all around South-East Asia. The results of these findings give an overall positive and current result that provides a useful point of reference in order to create a game design model that would offer a set of guiding principles for educational game designers to create engaging gameplay.
Menthol Crystal Vapor Inhalation In The Management Of Hypoxia During Dental Sedation: An Evidence For The Management Of The Silent Hypoxia Of Covid-19
Authors: Ogunsalu Christopher
Published: January 2022

Purpose: The objective of our study was to describe the effective use of menthol crystal vapor inhalation in the oxygenation of a hypoxic patient. The study also aims to affirm the possible role of this oxygenation effect of menthol crystal vapor in the management of hypoxia in early diagnosed COVID-19 patients.

Patients and Methods: This Study (the immediate oxygenation effect of menthol study), involved intra-operative oxygenation of a sedated, none COVID-19 patient undergoing surgical removal of a tooth together with a series of seven COVID-19 positive patients. The oxygen saturation of this single surgical patient which dropped to dangerous levels during the short surgery was elevated five (5) consecutive instances to a level above the pre-operative baseline following the inhalation of menthol crystal vapor. The series of seven patients with COVID-19 were administered with menthol via the menthol crystal Inhalation regimen and the improvement in their low oxygen saturation was monitored and documented.

Results: The only case in this study had its oxygen saturation increased repeatedly intraoperatively for 5 consecutive instances when it fell to a dangerous level of 84%. This single study together with the study of menthol crystal increasing the oxygen saturation of mildly hypoxic early diagnosed COVID-19 patients in an earlier study now calls for a modification of the current treatment modality for both in-Hospital and outpatient COVID-19 Cases.

Conclusion: The periodic inhalation of menthol crystal vapor intraoperatively and the utilization of the vapor in the menthol crystal inhalation regimen (MCIR) has been found to effectively manage hypoxia but it is also therapeutic for COVID-19 patients.
Theoretical determination of the regularities of the plane motion of the grain in the non-uniform air flow of the horizontal pneumatic channel of the aerodynamic separator
Authors: Stepanenko S. P. , Kotov B. І.
Published: January 2022

Annotation
Purpose. Improving the mathematical description of the motion of the dynamics of grain motion in the horizontal non-uniform air flow of aerodynamic separators.
Methods. Theoretical determination of the regularities of the plane motion of the grain in an uneven air flow determines the analytical method of research based on the compilation and analysis of the equations of motion of the grains in the form of a sphere in the air flow of the horizontal pneumatic channel of the separator. The mathematical model is formulated by obtaining differential equations of motion of the components of the grain material, which are represented by a material point and a complex indicator of aerodynamic properties – the coefficient of vitality (sail).
Results. The flat motion of the grain in the uneven air flow of the horizontal pneumatic channel of the aerodynamic separator through the sieve surface with cracks in the axial direction of air is absorbed.
The obtained equation of grain motion during horizontal air flow allows to determine the dependence of grain velocity in air-grain medium on a number of factors: geometric parameters of the separator, feed angle, initial kinematic mode of the material, and grain vitality coefficient.
Conclusions
1. An improved mathematical model of the dynamics of the motion of a solid particle in a horizontal air flow is formulated, which differs from those known in that it reproduces the action of unaccounted factors (non-uniformity of the velocity field, action of lateral forces, material concentration). It is established that the change of the sign of the air flow gradient in the cross section leads to a change in the direction of the trajectories of the light fraction KZM, which increases the completeness of the removal of the feed fraction to 90% and increases the separation of the seed fraction by 15-20%. up to 2-3%. Changing the diagram of the air velocity in the horizontal channel increases the velocity in the wall area, which increases the clarity of the division by 18-24%.
2. The solution of the system of nonlinear differential equations with initial conditions is performed in the MathCad software environment in the form of grain motion trajectories in horizontal air flow, which allows calculating grain motion trajectories differing in vitality coefficients and determining rational values of pneumatic gravity separators.
Keywords: variable air velocity, trajectory, lateral force, fractions, horizontal air flow, fractionation process, grain.

The method of measuring local accelerations transmitted to the hands of the employee has been improved. It is proposed to use accelerometers ANS 114-02, which are attached with adhesive tape to the holding handles of the shaker along the x and y axes of the orthogonal coordinate system. The y-axis is directed in the direction of oscillation and coincides with the longitudinal axis of symmetry of the handles, and the x-axis – along the forearm of the worker perpendicular to the y-axis. The estimation of the admissibility of the total vibration on the shaker handles was carried out according to the method, which consists in determining the root mean square values of the accelerations of longitudinal-vertical oscillations in the frequency bands up to 31.5 Hz. The oscillating loads on the handles of the manual fruit shaker operating in the vibro-shock mode are investigated. At the same time, local oscillations of non-constant action are transferred to the hands of the worker during working hours. The studies were performed at the highest perturbing forces in the range of operating shaking frequencies of 40–100 rad/s (6.37–15.92 Hz) on skeletal branches with a diameter of 90 mm at the base. Frequency-adjusted root mean square accelerations on the holding handles do not exceed the allowable values. Conclusions. Oscillatory loads on the hands of the worker through the handles, ensuring the retention of the manual vibratory shock shaker, do not exceed the allowable short-term local oscillations on the adjusted values of the root mean square acceleration and are: along the y-axis – 2.47 m/s2 (78.3 dB); along the x-axis perpendicular to the y-axis – 0.63 m/s2 (66.4 dB).

Annotation
Purpose. Improving the quality of distribution of technological material by choosing a rational scheme of the multicopter and technological equipment for it.
Reduction of damage to crops by terrestrial technical means in the process of plant protection through the development of a distribution and dosing system for multicopters.
Methods. The designs of multicopters are analytically investigated and the construction scheme of the multicopter and technological equipment is determined.
Results. The designs of multicopters are analyzed, and the design of the multicopter and the layout of the technological equipment are substantiated. The analysis of technological equipment for application with the use of plant protection multicopters is given. Based on the analysis of multicopter designs and their technological equipment, the advantages of their work are determined: they depend less on weather conditions and plant condition, but have a number of disadvantages, such as insufficient uniformity of material distribution and low productivity.
Conclusions
1. It is established that with the appropriate improvement, multicopters will perform the vast majority of work when applying plant protection products, especially on wet soils.
2. During the technological operation of spraying, the performance of the multicopter is reduced by 20 % compared to the AIT due to the cost of working time to replace the battery.
3. The distribution of material on the surface of the field by multicopters, when performing a technological operation has a high unevenness (up to 70 %).
4. To increase the productivity and quality of the working fluid distribution, it is necessary to change the layout of the drive propellers and process equipment in the design of the multicopter.
Keywords: agricultural multicopter, multicopter-sprayer, agricultural drone, liquid sprayers, ultra-low-volume spraying.
Service Experiences of Undergraduate Engineers
Authors: Rupnow Rachel , Davis Kirsten , Johnson Rachelle , Kirchner Elizabeth , Sharma Jyotsana , Talukdar Shahidur Rashid
Published: January 2022

The study discussed in this article examined the impacts of service experiences on engineering students. The study sought to identify themes in the service experiences of engineering students through a qualitative research process involving interviews, open coding, and thematic analysis. The participants included six students studying civil engineering or related disciplines who took part in a service experience within the previous year. Participants responded to open-ended interview questions designed to collect detailed descriptions of their service experiences. Employing integrated open-coding techniques and thematic analysis of patterns that emerged from the interviews, the researchers identified three themes from the student responses: motivation, learning, and perspective. These themes, especially when examined through the lens of Mezirow’s transformation theory, suggest that service experiences can motivate engineering students to participate in further service opportunities, seek jobs that involve actively serving others, and incorporate their attitude toward service into the engineering profession.
Service-Learning: A Powerful Pedagogy for Promoting Academic Success Among Students of Color
Authors: Sterk Barrett Michelle , Jenkins Isabelle
Published: January 2022

This article discusses a mixed-methods study that investigated the service-learning experiences of students of color at College of the Holy Cross to better understand how service-learning may be an effective pedagogical tool for reducing cultural dissonance and addressing related achievement gaps. Quantitative data were collected from over 1,500 students who had enrolled in 59 different service-learning classes. In addition, interviews were conducted with 13 students of color who had participated in service-learning. Findings indicated that students’ service-learning experiences paralleled study participants’ descriptions of how they learned most effectively. Furthermore, the findings suggest that service-learning may resonate for students of color because of the way in which (1) it enables students to integrate social responsibility with academics; (2) students of color can personally relate to the course content as well as the people and experiences encountered at service-learning sites; (3) service-learning reduces cultural dissonance by empowering students who are struggling to build confidence and feel that they belong in a highly selective, predominantly White college.
Fostering Collective Impact: Measuring and Advancing Higher Education’s Contributions to Civic Health and Equity in Colorado
Authors: Orphan Cecilia , Romero Deborah , Diaz-Solodukhin Liliana
Published: January 2022

Although colleges and universities typically employ input metrics such as volunteer hours to assess the contributions of campus-community engagement, they often fail to measure outputs in reciprocal partnerships with community leaders. This article discusses a community-based participatory action research (CBPR) study that centered on community expertise and assessments of campus-community engagement in determining the outcomes for regional civic health and equity. The study used collective impact and decolonial theories, and involved community and campus leaders from three Colorado universities working collectively to develop instruments for determining measurable contributions of campus-community engagement. Findings demonstrated that collective impact and CBPR are well suited to supporting reciprocal partnerships between universities and community leaders aimed at assessing and decolonializing campus-community engagement. The findings also revealed that campus assessments differed from community assessments in illuminating ways. The article concludes with actionable recommendations for campuses interested in fostering collective impact and CBPR in efforts to improve regional civic health and equity.
“I Am So Angry I Could . . . Help!” The Nature of Empathic Anger
Authors: Bringle Robert , Hedgepath Ashley , Wall Elizabeth
Published: January 2022

Empathy is widely viewed as a precursor to civic engagement, a mediator of other responses during civic engagement, and an outcome resulting from civic engagement. However, empathic sadness is can be biased toward helping a lone victim, a member of an in-group, a person who is physically nearby, and an individual who is personally identified. Alternatively, empathic anger occurs when an observer experiences anger, rather than sadness, on behalf of a victim as the basis for inferring social injustice and for taking action. Empathic anger represents an untapped dimension of motivation that is not captured within other approaches to motives for civic engagement. This article details three studies which found that those reporting higher empathic anger were altruistic, not aggressive, oriented toward advocacy rather than charitable service, nonprejudicial, endorsed a social justice perspective, and active in communities outside (and independent) of campus activities. Implications for future research on motives for civic engagement are presented as well as implications for designing service-learning courses to promote empathic anger as a basis for action directed at social justice issues.
“Cutting Edge” or “Ridiculously Isolated”?: Charting the Identities, Experiences and Perspectives of Full-Time, Non-Tenure Track Faculty Engaged in Service-Learning
Authors: Matthews Paul , Wilder Shannon
Published: January 2022

This article discusses a phenomenological study that investigated the complexity of identities and experiences of 11 full-time, non-tenure-track faculty in five different career tracks engaged in service-learning at a large public research university in the southeastern United States. The study employed interviews and focus groups from which key themes and findings emerged. Non-tenure-track faculty participants reported: feelings of uniqueness/isolation based on their roles but also enhanced flexibility to incorporate service-learning from intrinsic motivations; difficulty carrying out scholarship on service-learning, despite an interest in doing so; lack of recognition compared to tenure-track colleagues; the acquisition of expertise around the pedagogy; and finding particular value in the support and professional development offered by the institution’s service-learning office. The authors discuss the findings in the context of prior research on non-tenure-track faculty roles and settings, service-learning faculty involvement and motivation, and implications for institutional policy.
