Authors: Haryati Sri , Trisnowati Eli , Siswanto Siswanto , Al Firdaus Moch. Malik
Published: January 2022

In line with 21st-Century learning, the 2013 Curriculum highlights the development of critical thinking, problem analysis, problem-solving, decision making, and creating something new. Professional teachers need to facilitate students in developing these abilities. This research describes how the teachers plan the higher-order thinking skills (HOTs). This research is qualitative research with a descriptive design. The respondents were four teachers with 0-40 years of teaching experience. The data were collected qualitatively through documentation and interviews. The results showed that HOTs were not clearly expressed in the teacher's lesson plans at teaching experience levels of 0 to 10 years and 10 years to 20 years. Teachers with 20 to 30 years of teaching experience and 30 to 40 years of experience have expressed HOTs explicitly and completely in all parts of the lesson plan. Teachers have an important role in facilitating higher-order thinking skills that can be seen through the lesson plans. The lesson plan must describe the development of higher-order thinking skills holistically. Teachers need to review each lesson plan to be coherent in every part and relevant to 21st-century learning.
Test and evaluation method for greases in grease-sealing rotary shaft seals
Authors: Hahn Susanne , Feldmeth Simon , Bauer Frank
Published: January 2022

Grease-lubricated sealing systems show starved lubrication much more frequently than oil lubricated sealing systems. Different greases provide different lubricity to the sealing system. A test and evaluation method was developed that allows to assess the lubricity of different greases and to compare them with each other. The test and evaluation method consists of a test run and a subsequent analysis of the test components. The test run comprises a 24-hour speed collective and is performed on a test rig using real sealing system components. For the evaluation method, eight criteria are analysed, which are rated suitable for evaluating starved lubrication. The criteria include parameters measured during the test run, such as friction torque and temperature, as well as parameters inspected in the subsequent examination of all test components. All criteria are assessed and combined to an overall score, that allows to directly compare different greases with each other. The test and evaluation method developed reveals significant differences between 23 greases examined. Thus, the lubricity of greases in sealing systems can be analysed and compared much more quickly than in the past. Thanks to the rapid testing and focused evaluation of the relevant criteria, greases can be tested much more cost- and resource-efficiently than before.

Published: January 2022

Every year 23 % of the world energy consumption is caused by friction and wear. Especially now and in future bearings and gear boxes will be exposed to electrical currents so lubricants have to prevent the components from new damage mechanism. The usage of Ionic Liquids as conductible lubricant additives is in discussion for a longer period of time, but right now it was not investigated how these liquids could be affect by electrical currents itself. Generally, lubricants in industry are compounded by base oils, additives, and thickeners. All these ingredients are isolators and not able to discharge electrical currents. In these joint research project, different Ionic Liquids with different conductivities have been exposed to defined electrical currents. For that experiments a new current feed setup has been developed, where the liquids and model lubricants were exposed to electrical currents under temperature control. The influence on the liquids by the current feed was chemically quantified by using IR-Spectroscopy, rheology and conductivity measurements. The Ionic Liquids react, depending on their chemical structure, very different on the current feeds, some of them has been destroyed totally.

Authors: Shtanov E. Yu. , Polyakov M. V.
Published: January 2022

The paper concentrates on development of optimizing methods for the GOST R 34.12-2015 "Magma" cipher algorithm when it is implemented on 8-bit microcontrollers. There is a number of techniques in the paper, which being used, allow you to create the specialized implementations of the algorithm: 1) focused on the operation speed; 2) focused on reducing the memory used; 3) optimal which involves the best solutions based on two previous implementations. Each optimization method is represented by description and performance indicators of the results obtained in comparison with the direct implementation of the algorithm. So, in the case of optimal algorithm implementation the enciphering process is 11 times accelerated, and an amount of the occupied memory is 1/32 of the microcontroller's memory. The built-in compiler tools were used to optimize the software code. The techniques described are applicable to any 8-bit platform.
Formation of the composition of programs for the knowledge–intensive industry development using bacterial optimization algorithms and fuzzy logic methods
Authors: Bulygina О. V.
Published: January 2022

Today the knowledge–intensive industry development is carried out by the programs that combine a set of innovation and investment projects aimed at achieving a single goal and implemented in general constraints. The presence of a larger number of project characteristics (in particular, terms, resources, performers, etc.), which must be taken into account when forming the composition of the program, leads to the formulation of the problem of multicriteria optimization. As its solution, it is proposed to use an algorithm of bacterial optimization, supplemented by a procedure for forming initial positions using fuzzy logic methods.
The perception of the issue of spawner harvesting in lakes by the owners and managers of the entities authorised to commercial and reacreational fisheries management
Authors: Trella Marek , Wołos Arkadiusz
Published: January 2022

In recent years, the issue of spawner harvesting has been frequently addressed by different groups of stakeholders involved in the exploitation of fish resources. The increasingly numerous angling circles, which use these resources recreationally, question the current rules of fish stocking management in Poland, and its legal and economic status has become the focus of scientists’ interest. The aim of the study was to present and discuss the results of a questionnaire survey addressed to managers and owners of lake fisheries entities in order to identify the determinants of fisheries management related to spawner harvesting. Questionnaires were collected from a total of 76 entities, and concerned 1921 lakes with a total area of 174,078 ha, which accounts for more than 64% of the total area of lakes used for fishing and angling purposes in Poland. The paper presents inter alia the occupational characteristics of the respondents; their positions on the effect of spawner harvesting on lake ecosystem, environmental protection, and social factors; anglers’ assessments of spawner harvesting; the actual and potential methods for regulating this harvesting; and the negative and positive effects of the introduction of a prohibition on this harvesting. The results show that the respondents under study generally do not see the need for the introduction of additional (except those already in place) regulations concerning spawner harvesting, most of them notice the adverse effects of their introduction, but they are also aware of the possible changes and their impact on management.

This paper presents a study regarding the gear hob’s rake face grinding possibilities and its consequences. A simple theoretical lined surface is considered. The mathematical model of the reciprocate meshing of surfaces was applied. It was proven that the proposed form of the rake face cannot be obtained because an undercut of inacceptable extent occurs. It is also proven and sustained by CAD modeling that using a simplified, flat grinding disk, the undercut is avoided, but the phenomenon of transection appears.
Comparison of TCP SIAD and TCP BBR Congestion Control in Simulated 5G Networks
Authors: Scharnitzky Donát , Krämer Zsolt , Molnár Sándor
Published: January 2022

5G cellular networks have introduced a completely novel air interface called New Radio (NR). This technology delivers numerous benefits compared to previous generations, including significantly higher peak data rates. However, due to the propagation properties of the frequencies used in NR, the volatility of the available downlink capacity also increases. In this paper, we study two TCP congestion control algorithms which are designed to be able to quickly utilize sudden increases in available capacity. We present an implementation of TCP SIAD in the ns-3 open source network simulator and compare its performance with TCP BBR using the mmWave module of the simulator.
Changes and Perspectives in Teacher Training Methodology
Authors: Harangus Katalin , Horváth Zsófia-Irén , Kovács Gabriella
Published: January 2022

School closures induced by the COVID-19 crisis have led to the rethinking and reshaping of teacher training considering the norms of online and blended learning, and the pressure to embrace the possibilities offered by information and communications technology. We propose to examine the new perspectives and necessary changes related to three domains in which our institution – the Teacher Training Institute of Sapientia Hungarian University of Transylvania, Faculty of Technical and Human Sciences – offers training: foreign languages, social sciences, and engineering. Different areas of education have been affected in different ways by the pandemic. In language teaching, familiarity with pre-existing platforms and programs helped the transition to online education. In the field of social sciences, the transfer of theoretical information did not cause any particular problems, but the development of interpersonal relationships, interactivity, and communication became more difficult. In the domain of engineering, practical education has become nearly impossible, as in order to develop certain practical skills students need access to laboratories equipped with special tools, devices, and instruments. In our study, we will focus on ways of updating and developing our methodology courses based on new paradigms and good practices presented in the specialized literature, also reflecting on feedback received from our teacher trainees related to their difficulties and needs revealed by the shift to online teaching.

Design Methodology and Tools in Factory of the Future
Authors: Adrian Florea , Ion Mironescu , Daniel Crăciunean , Daniel Morariu , Daniel Volovici
Published: January 2022

This paper presents a design method and tool developed to support the skill forming activities in the DigiFoF network (https://www.digifof.eu/). The focus is on training of manufacturing system design skills both as HEI education and vocational training, but preliminary design of new manufacturing systems is also supported (e.g in the development of small business process scenarios).

We proposed a model-based methodology for solving of the manufacturing system design problems The methodology and the supporting tool are centred around a less abstract Domain-Specific Modelling Language (DSML). The language is easy to learn due to its few components.

A modelling and simulation environment named Digital Production Planner Tool (DPPT) was generated from the metamodel of the DSML. The degree of abstraction used by this tool corresponds well to the intended use in training and preliminary design.

Our method incorporates by design the possibility to impose constraints at the modelling language level to limit the modelling space to feasible/possible solutions. The resulting tool enforces these constraints in the use and supports the development of feasible designs even by inexperienced designers.

The access to the conceptual model allows the translation of the model to other modelling language like Petri net. This extends the support for the design methodology.

The whitepaper presents a use case for the developed method and tool: the design of a chocolate manufacturing line.

Authors: Brad Ana , Brad Maria
Published: January 2022

This paper presents a "smart" clothing product implemented as a jacket that contains sensors, a processing unit for display and interaction. The system has the ability to remotely read the data provided by the sensors, ensuring the monitoring of several parameters of the wearer.

The following characteristics have been considered: body temperature and humidity, atmospheric temperature, pressure and altitude, the heart beat and number of steps converted into the number of calories consumed and traveled distance.

The data is acquired and processed by an Arduino AT Mega 2560, via the I2C bus, digital ports and analog to digital converters, depending on the type of sensors. The processed information is printed on a 128x64 pixel display. To be able to view more pages of information, one can interact with the 4-key keyboard that has been connected to the digital input ports or through a proximity sensor, which will function as a gesture sensor.

The processed information can also be accessed from a web server, built on the ESP8266 Wi-Fi module, connected to Arduino's TX/RX lines. A mobile phone or another device can connect to the Access Point and open a web page which displays the values of all sensors, as well as other information. The embedded system was inserted on a jacket and wired according to the sensors and modules usage.

The Smart City is not a new concept. In fact, the digital city appeared in the information era and the wireless city emerged in the Internet era, but the Smart City had not been clearly defined until the digital era. Unlike traditional informatization, a Smart City is not simply the combination of informatization in all industries. Not only is a smart city a top-leadership project, it reshapes the digital capabilities of all industries in a city, while also addressing systematic challenges.

This paper presents Huawei perspective on Smart City development, including the conceptual framework, governance, type, connectivity, structural enablers. The paper also describes the strategic vision and a Smart City construction path, from the strategic planning, solution design and implementation.

ORATOR v2 is a new 1.5M word corpus of Czech monologues, delivered to a live audience in semi-formal to formal settings. It was designed to chart the space of naturally occurring monologues which can be obtained for corpus processing. As such, it aims for diversity but does not attempt any balancing of subcategories, recognizing that some types of data are inherently easier to obtain in high volume than others. The transcription guidelines and annotation tools employed are the same as other recent spoken corpora published by the CNC, which facilitates interesting comparisons between various types of spoken Czech. The present paper sketches out three case studies, comparing ORATOR to the informal conversations of ORTOFON v2 in terms of the frequencies of demonstratives and hesitations, as well as lexical richness.

The paper focuses on dynamics of changes of several linguistic and text properties in diachronic development of Czech. Specifically, we analyze the proportion of identical word-forms (types), the average type length, text length, the proportion of hapax legomena, the moving average type-token ratio, and entropy. For the analysis, seven translations of the Gospel of Matthew from the 14th to the 21st century were used. The study reveals some differences in dynamics of changes of particular properties.
Suspended sediment in lowland rivers – towards identifying the ratios of mineral and organic components and their variation during the year
Authors: Skolasińska Katarzyna
Published: January 2022

Concentrations of suspended sediment transported by rivers are influenced by interactions between multiple drivers that act on a range of spatial and temporal scales. Such levels vary over the year, as well as across multi-year periods. Most conventional approaches to determining suspended load are based upon analyses of total suspended sediment concentration (SSC), i.e., the sum of mineral and organic matter. This approach makes it difficult, if not impossible, to determine the impact of multiple environmental factors on changes in suspension concentration precisely. The present paper focuses on the mineral and organic components of suspended sediment with the aim of determining how our knowledge of the share of each individual component can improve interpretations of SSC fluctuations during a hydro-logical year. The analysis conducted (personal and other researchers’ results) has shown that mineral and organic suspensions demonstrate mutually incompatible opposite trends under influence of environmental factors. This analysis of organic components identifies clear seasonal trends, which indicates that organic suspensions of autogenous origin have a strong influence on the dynamics of changes in suspension concentration; such analyses are rarely included in assessments of SSC dynamics.
Economic Cyber-Espionage in the Visegrád Four Countries: a Hungarian Perspective
Authors: Cristani Federica
Published: January 2022

This article explores the regulatory framework of reference of economic cyber-espionage in Europe, with a particular focus on the V4 region (comprising Slovakia, Hungary, Poland and the Czech Republic) and taking Hungary as a case study. Europe Union member states, including the V4 countries, are particularly exposed to economic cyber-espionage, because of the advanced know-how of the companies based therein. Under international law, there exists no uniform approach to the matter; also at the European Union level, the legal framework appears rather fragmented and the same holds true at the national level and within the V4 group, where each country has adopted its own relevant regulation. After a general overview of the relevant international and EU regulatory framework of reference, this article overviews the modus operandi of the V4 and examines its approach to economic cyber-espionage, with a special focus on Hungary as case study. As already remarked at the European and international levels, cybersecurity policies and regulations, including those regarding economic cyber-espionage operations, should be drafted in coordination among states; the V4 group can become a privileged platform of discussion to advance in the regulatory harmonisation of the issues at stake.

The study aimed to evaluate the effectiveness of functional and motor activity restoration, including the walking function, in patients after an ischemic stroke using the ExoAtlet lower limb exoskeleton.

Patients and methods. A clinical study was carried out on 42 patients who had undergone a cerebral infarction in the mid cerebral artery system with a post-stroke paresis of the leg, and who had undergone a rehabilitation course in a round-theclock hospital during the early recovery period. Patients were randomized into two equal groups comparable in terms of the stroke severity: the patients in group 1 were receiving a standard rehabilitation program (control group), the patients in group 2 were additionally receiving a course of gait rehabilitation using the ExoAtlet exoskeleton - 10 sessions, 5 sessions per week for 14 days.

Results. The study demonstrated the effectiveness of the ExoAtlet exoskeleton used in the rehabilitation of stroke patients over the standard course of rehabilitation. The advantages include a decrease in the hemiparesis degree, an increase in the muscle strength of the paretic limb, an improvement in balance, an improvement and acceleration of the walking process. The obtained results of the instrumental study confirmed the benefits of physical training on the Exoskeleton, which was demonstrated through an increase in stability and balance, as well as through a decrease in the energy consumption index for maintaining the stable verticalization.

Conclusion. The usage of the ExoAtlet exoskeleton increases the effectiveness of rehabilitation measures and improves motor and functional activities of patients who have suffered a cerebral stroke.

Implementation of qualia structures provided by relative adjectives and composites in German
Authors: Glushak V. M.
Published: January 2022

The present paper deals with the semantic representation of attributive elements in the nominative group − relative adjectives and composites. The aim of the present study is to analyze the semantic representation of a predominantly noun in an attributive group with reference to Qualia structures, as applied in J. Pustejovsky’s theory of generative lexicon, and their realization through relative adjectives and composites, which are direct explicators of the semantic structure of predominant words (nouns). The study is based on the 150 most frequent relative adjectives identified on the basis of the electronic corpus of the German language. Relative adjectives qualify as Qualia structures and can denote objective constitutive (material and origin), formal (physical parameters, colour, time, place), telic (purpose and function of an object) and agentive (information about the creator, artifact, natural genus and causal chain) properties. The system of relative adjectives demonstrates a wide range of semantic meanings that are expressed in German by other linguistic means, e.g. composites. When describing the possibility of implementing Qualia structures in the noun group, other correlative linguistic units, such as composites, are analyzed. The variation in the use of nouns in composites and relative adjectives formed from them helps to actualize the presence of a feature in a particular situation, to give the nominal groups a terminological character and to make the transition from one qualification group to another.
