METHODS OF ARTIFICIAL INTELLIGENCE IN ECONOMICAL AND LOGISTICAL EDUCATION
Authors: Udvaros Jozsef , Guban Akos , Guban Miklos
Published: February 2023

The artificial intelligence, also soft computing is more and more relevant in practice and their mystification causes plenty of misunderstandings. There's a need in secondary schools as well as in non-technical/scientific higher education to introduce them in an understandable way for later use. So in our lecture and article we show the applicability of soft computing in an easy to use simulation. In today's computer science education environment deterministic algorithms play a large role, the students learn, understand and maybe even know how to implement them. It would be important to make solutions, techniques which don't rely on traditional deterministic observations known and understandable to not only students that are interested in computer science. The best solution is to reach the results of certain searching tasks. Since in our BigData based world these techniques are the core of procedures, there's a huge importance for the high-level understanding of these techniques in secondary school. There's no need to know the functioning of the core. In the first step importance of optimization tasks need to be introduced and made understood, as well as their practical problems and relevance in real life. In the next step it should be shown, that if we make concessions in the purpose of optimization (we show this through an example that this is achievable) with the help of other, less mathematically correct, approaches we get really good results. In the article we show with great detail through a case study an optimization task, show its relevance then we introduce a simulation tool which's AI based. With the use of this tool we go through all possible solution ways, and compare how two differing AI based systems behave. After the applied simulations we rate the results for the students/listeners and examine their importance. We also draft in short how to interpret the simulation results and what their efficiency means. We show as well what role running time, (speed) step number, number of parameters as well as practicable parameters play. The article shows how we can use this in education through a case study.
E-LEARNING MARKET IN ROMANIA
Authors: Condruzbacescu Monica
Published: February 2023

The paper focuses on e-learning market in Romania. The e-learning market in Romania is underdeveloped compared to what is happening in this field in other European countries. Nowadays, any company or organization needs an employee training program, be it pharmaceutical, banking, sales or multinational companies. As a result, firms that want to provide training to acquire the skills needed to perform a particular job show two main trends: on the one hand, they turn to foreign companies, whose specialization is training and team building, and on the other hand, there are people in the company themselves who have the task of providing that training. The paper also presents trends and perspectives in e-learning and the first online platform that prepares young people for the current labor market- laboratoruldecariere.ro. Digital Economy and Society Index is another important issue. The DESI, calculated annually, monitors member states performance on the following levels: digital connectivity, digital competences, online activity, business digitalization and digital public services. It helps EU countries identify areas requiring investment and priority measures. In Romania, the level of digitization of the economy, as well as the digital competences of the population, are relatively low and makes progress in most DESI dimensions difficult. The conclusion is that employers and companies providing online training think that the market is rising and in the coming years, even if it does not replace traditional training, e-learning will be the main refuge of employers. The e-learning market is certainly growing, and European-funded projects that have been developed lately have managed to boost it both in the public and private sectors. E-learning will not completely replace the classroom courses, but it will expand them. It will also create training opportunities for people who do not have access to training for various reasons (the most important being time and money). Online training methods have advantages linked to costs, ease of program implementation to a larger audience from companies, making available more content types. The e-learning system offers one of the best variants to produce tangible results. This is perhaps also the main reason why this industry is experiencing a significant increase worldwide. Researchers estimate that e-learning is a growing industry with huge potential that will find its place in the next few years in all pre-university and university education institutions, state or private, but also in all major corporations.
HIGH IMPACT CYBERSECURITY CAPACITY BUILDING
Authors: Nevmerzhitskaya Julia , Norvanto Elisa , Virag Csaba
Published: February 2023

The shift of our societies towards automation and connectivity is accompanied by growing vulnerabilities that can be exploited to cause effects ranging from nuisance to large-scale breaches of sensitive personal data, terrorism and destabilisation of democratic processes . To achieve preparedness and resilience, cybersecurity skills need to be continuously advanced at all levels of ICT and security personnel, in a constant learning process, to address complex demands of individual and organizational level capacity building through trainings and exercises.
In this article authors describe a proposal for a common cybersecurity training framework enabling practical, operational and hands-on trainings that are adaptable to changing threat conditions, and a methodology to transform user needs into interoperable training specifications to be used by cyber range and cybersecurity training providers and that can take advantage of simulations and knowledge transfer solutions. Such a framework improves cybersecurity training capabilities by leveraging dynamic simulation environments for delivery of realistic training scenarios enabling participants and organisations to prepare for current and future threats. The framework provides the foundation for systematic development of cybersecurity skills at the individual and organizational levels. It consists of a multidisciplinary cybersecurity training methodology; a model that describes the various skills required to perform cybersecurity duties, as well as the levels of proficiencies; and the training and skills evaluation methodology.
The innovation potential of the proposed training framework comes from a holistic approach to understanding capacity building in terms of translating end-user needs into training scenarios and applying a human-centred and organisational approach to cybersecurity, taking into consideration behavioural aspects of training.
LANGUAGE AND SAFETY: THE BENEFITS OF USING AUDIO VISUAL AIDS IN TEACHING AVIATION ENGLISH
Authors: Marculescu Corina
Published: February 2023

Aviation English is unique in English for Specific Purposes (ESP) because in the aeronautical field, language is inseparable from safety. The passengers' lives and safety depend on the accurate communication between pilots and air traffic control officers (ATCOs), on the precision of their language. My paper puts forward the suitability and effectiveness of using audio-visual aids (video clips, photographs, diagrams, maps, authentic audio recordings of voices with a variety of accents and pronunciations encountered in international flights) in aviation English teaching. The use of audio video digital technologies helps the students (especially aerospace engineering majors and air force academy students) to become familiar with the operational environment of aviation, to obtain a 'feel' for the conditions in which pilots and controllers communicate. Properly selected and relevant digital video or photographs "introduce" the students into the airport architecture (taxiways, runways, hangars, cargo areas etc), in the control tower or in the pilots' cockpit, into the world of pilots and ATCOs, of technicians and aerospace engineers. I will show that what matters even more is the teacher's passion for the field and his/her consequent ability to devise the best and most motivating pre- and post-watching activities and discussions to stimulate the students to debate the aviation incidents presented, to practice the vocabulary they are likely to encounter in an aviation context, the standardized coded phraseology used in pilot-controller conversations to communicate clear, concise, unambiguous, internationally recognized messages of a routine nature, and the spontaneous, non-coded "plain" English which is crucial to master in non-routine, unexpected or emergency operational situations. The paper proposes a content-based, communicative approach to teaching Aviation English, supported by audio-video technology - which Generation Y students in particular find engaging and challenging. Technology properly embedded in the course and relevant to projects or seminar activities maintains the attention of today's visual learners focused on the subject matter and inspires and motivates them to research and discover more about the communication in the aviation field.

Published: February 2023

The article describes the experience of increasing efficiency of competence formation of students of applied information science. Authors underline the necessity of improving theoretical materials of disciplines and elaborating new methodical approaches to teaching technical disciplines for students in engineering of higher education institutions. One of the primary problems of future software engineers training is the lack of efficient approaches to ICT competence formation and particularly in development of its creative and research components. As a solution to the problem, application of project activities for teaching disciplines which are related to information and communication technologies is proposed as well as the active use of web 2.0 services. The authors point out the following advantages of using web 2.0 in the educational process: services allow increasing students' cognitive interest to the problems of the academic discipline, diversifying the main activities during the project, presenting design solutions in a visual, interactive form, forming their own unique digital content. The article presents a mental map of web 2.0 services with categories and particular resources that will be useful for carrying out applied informatics bachelors' projects. The authors offered examples of project topics in the disciplines of computer science, application programming, information security, design activities, and development of Internet applications. In addition, the pedagogical capabilities of such services as comics creation service (Pixton), development of mental maps (mindmup), creation of infographics (Piktochart), organization of teamwork (Yougile) are described. The research results showed that the use of web 2.0 network services while applying the project approach in the process of developing ICT competence among applied informatics bachelors allows not only increasing interest in technical disciplines study, enhancing information exchange, communication among students, but also developing ability of cooperate, teamwork, as well as creative and research activities. The article reveals methods of applying network services Web 2.0 for organizing educational projects. The review of services according to categories is offered and specific examples of their application for organizing project activities while studying ICT disciplines are described.
EYE MOVEMENT ANALYSIS SYSTEM IN RELATION TO BIOMECHANICAL PERTURBATIONS
Authors: Baritz Mihaela ioana
Published: February 2023

In its totality, behaviour has apparent cognitive and observable findings, such as language, gesture, body, head, upper or lower limbs, facial and ocular expressions, etc.; or subconscious, physiological, non-transparent such as micro-modulation of heart rate and physiological parameters, modification of ideo-motor activity etc. Analysis of eye movements is an objective way of assessing the state of concentration and attention in cognitive processes. Fundamental and applicative research in this field has highlighted a number of defining aspects of the cognitive process that relate to the different positions and movements of the eyeball.
In this regard, a portable eye analysis system, correlated with biomechanical disturbances induced by the posture of the subjects was developed in the paper. The system is used to simulate synchronized postural disturbances at the same time as recording changes in human body stability and eye movement changes. The second part of the paper describes the experimental system; the sample of subjects is chosen according to the criteria established by the analysis procedure and also the recording procedures under stable and reproducible environment are developed. In the final part of the paper, results from applications and some conclusions are presented.
Experimental application can determine the mode of response of eye movements in relation to the type and level of biomechanical perturbation. This response defined by the eyeball eye movement parameters can characterize the state of focus, attention or involvement by assessing behavioral coefficients. The results of the determinations are at the same time a mechanism of cognitive training and evaluation of adaptability capacity to the conditions of action of random perturbations.
DEVELOPING ALGORITHMIC THINKING BY EDUCATIONAL COMPUTER GAMES
Authors: Czakoova Krisztina
Published: February 2023

Basics of algorithmic thinking should not be limited to create right solutions and express them by a computer program, but should also be used a suitable methodology based on problem solving, preferably in a playful way. In many cases at school most of the learners consider the topic of algorithms as hard and not very attractive. For beginners in programming the knowledge of specific algorithms is not so important. The ability to understand principles of algorithms, as well as to find own algorithms for new problems are more desirable. One main educational objective is to know that an algorithm prescribes exactly what to do in the possible situations. The educational computer games based on the use of basic control structures do a good service to pupils can understand correctly how to get to the solution, using clearly defined steps with immediate feedback, with the possibility of visualizing the sequence of steps (with the possibility of corrections). Students gain new knowledge based on their own observation and discovery. The games also motivate the students to improve their algorithms to find more efficient solutions in the strategy of games. The aim is for pupils to acquire new knowledge by exploring and learning by doing. The main aim of the paper is to show a way of learning principles and concepts of algorithms by using computer game that is much easier to comprehend by the learners and makes them more fun. During the creation of the game, which was inspired by the well-known programmable toy Bee-bot, we tried to comply with the didactic principles of illustrationality, appropriaty and individual approach.
A MULTIDIMENSIONAL APPROACH TO CYBER SECURITY FOR CRITICAL INFRASTRUCTURES
Authors: Patrascu Petrisor
Published: February 2023

In today's society both people's everyday lives and organizations are surrounded by an increasingly digital world. The essential services in a society are provided through critical infrastructure. Their activity will in turn be increasingly dependent on digital technologies. ICT systems are designed and developed on the activity profile of the critical infrastructure sectors, such as the industrial, military, medical or financial sector. Therefore, the cyber security for critical infrastructure has become, as a multidimensional system, a strategic form of protection for a number of states and international organizations. Therefore, many states of the world, on the basis of certain criteria, have identified and designated their national critical infrastructures. Once they have been identified, there have been taken increased security measures, including in the area of cyber security. Cyber-attacks that target critical infrastructures also needs to be considered. Planned targets are analyzed to the smallest detail to find out the vulnerabilities of the attacks. Usually, the cyber-attackers target critical infrastructures in order to obtain the most valuable information and to affect the functionality of the services. In recent years, these types of attacks are characterized by complexity, persistence and advanced techniques, supported by key actors or state-sponsored actors. Cyber attackers are permanently looking to exploit any vulnerability, either it's technical, human or procedural. Therefore, considering these aspects, we can emphasize that establishing a strong security has long exceeded the exclusive assurance of a technical security. Thus, multidimensional is highlighted in several areas of interference based on a holistic approach to cyber security for critical infrastructures.

The connection between management and leader is an increasingly current problem. Through e-learning, which means the use in education of new technologies, electronic media and information and communication technologies (ICT), we bring added value to the Romanian education. E-learning, in fact, includes all forms of educational technology in learning and in providing education. E-learning is associated in the specialty literature with multimedia learning, computer instruction, internet, virtual education.
Thus, through e-learning, the competence of the manager and the assimilation by him of the leadership status including in the school and education institutions are better outlined.
Our article tries to develop the new roles and contributions of e-learning in the combination of the two statutes.We will highlight the importance of e-learning in education and learning.We are interested in understanding the importance of e-learning, the relationships that are created between learning and their use in education. We will be able to identify the different educational situations in which the use of e-learning will be efficient and constructive. The society is constantly changing, and today's students need new learning situations and innovative strategies. The teacher must adapt to the needs of the students and for this to be possible, the use of new technologies in education is a useful solution. The e-learning platforms will help the teacher in the teaching activity, but also the manager, seen as a leader. The manager's activity is important, even more so, as this one through the competences it has will influence the educational activity, obtaining excellent results.

Authors: Mata Liliana , Poenaru Alexandra georgiana
Published: February 2023

The purpose of this study is to analyse the codes of ethics and university deontology in order to identify the rules for the use of information technology. In the introductory part of the study, there is highlighted the importance of observing these rules by the university teachers. From a theoretical point of view, there are provided the characteristic elements of the code of ethics and university deontology and there are specified concrete examples of rules of the use of information technology included in the codes of ethics in the university field at international level. At the basis of the code of ethics there is a set of principles and norms that the members of the academic community agree to respect them. The research methodology is qualitative, focused on the use of content analysis. The codes of ethics of 38 universities from Romanian education were analysed to identify the rules for using information technology. Content analysis of the themes related to the rules of the use of information technology is performed based on the indicators derived from the theoretical part. The results of the analysis led to the fact that there are few explicit rules regarding the use of information and communication technologies included in codes of university ethics. It is recommended to introduce specific rules in order to raise awareness of the importance of respecting these rules by university teachers and students. Therefore, the university codes of ethics will be reconsidered from the perspective of the development of information technology.

Published: February 2023

In a time when technology is advancing with extreme rapidity, perhaps the greatest challenge to be answered by new generations is the development of the skills that allow them to function in a digitized society. This challenge is addressed on the one hand to the average man, for whom mastering the operation in the IT&C field is a functional necessity, as well as to those passionate about programming and electronics. If it is necessary for the first ones to identify the simplest and friendliest ways by which the new technologies can be implemented, the formation of the second category implies the inclusion in the educational process of the newest technologies and the familiarization with them up to the level at which it can unlock creativity and development. In this paper, we aim to address the issue of Single-Board-Computer (SBC) devices in terms of understanding the educational potential that these devices have, but also how they can be leveraged in learning. In fact, these devices have been developed specifically for educational purposes or to be used as embedded systems. They represent small computers having all components embedded on a single silicon board and having CPU, GPU, memory, input / output and other features required for a functional computer.
For this purpose, we will analyze comparatively the content of the curriculum of the most important technical universities in Romania and abroad to identify the extent to which such devices are taken over by the universities, highlighting the advantages and disadvantages of their use. Depending on the results obtained, we will develop a set of measures aimed at optimizing the educational potential of SBC devices, especially Raspberry Pi devices which are the most widespread SBC.

Published: February 2023

During past years, virtual reality (VR) and augmented reality (AR) improved a lot from both accessibility and hardware capabilities perspectives. Currently, this type of software applications is encouraged to be part of various domains. This paper presents how virtual reality technologies can provide a novel, immersive, approach of one of the most used data science tasks, respectively data analytics, that can be used to enhance the effectiveness of the organizational knowledge transfer. Knowledge transfer, a process used in various industries including education, business, social and technology, plays an important role in the overall learning process, introducing new ways of sharing resources and people experience. As a data scientist, it is usually said that about 80% of the time will be used doing EDA (exploratory data analytics scenarios). Our research targeted the enhancement of organizational knowledge transfer processes by using immersive EDA. Our paper emphasizes the fact that VR offers extended possibilities for sustaining data analytics strategies, improving them with a new immersive perspective. Virtual learning environments can be used to build skills and one challenge for virtual reality, when applied in education or training, is to assess Virtual Environments effectiveness. Immersive data analytics can ease the effort of quantifying how effective a specific virtual scenario was for a group of users. The presented study also emphasises on how VR technologies can provide more detailed immersive analytics that can be used in optimizing knowledge transfer and implicitly learning processes, by potentially analyzing every move of the learners, assessing the evolution of the user learning/performance, respectively understanding user reaction speed (response times) in various contexts similar to real world scenarios. Also, through immersive analytics, it is possible to determine learners emotional state and their level of attention, being possible to provide a more personalised interactive experience for enhancing learning efficiency.

Published: February 2023

An experimental study was conducted to predict the residence state and country of students based on their response provided in the two different ICT survey held during the academic year 2015-2016 and during the academic year 2017-2018. The first dataset was consisted of 560 instances and 59 features and second dataset was comprised of 331 instances and 46 features. We considered the state in the first dataset and country in the second dataset as the response variable and rest of all are assumed as predictors after self-reduction few features. The datasets are trained and tested with the splitting and k-fold Cross Validation (CV) using three popular supervised machine learning classifiers named Artificial Neural Network (ANN), Sequential Minimal Optimization (SMO) and Random Forest (RF) in the Weka 3.8.1 workbench. In the state prediction, the RF classifier outperformed with highest prediction accuracy of 83.39% the ANN and SMO at 6-Fold of the CV method. The maximum accurate prediction count for the Punjab student is found 239 out of 282 and for the Haryana student is found 228 out of 278 with k=6. In the country prediction, the best fitting model will be presented with highest prediction accuracy. The comparison findings are described about state versus country prediction of student with important measures like accuracy, error, F-score, Confusion matrix, True Positive Rate (TPR), False positive rate (FPR) and ROC curves. Further, these state and country predictive models may support the real-time prediction module of student's demography prediction towards the technological awareness.

Published: February 2023

The basis of requesting resources from a remote server for all browsers is protocol HTTP/1(HyperText Transfer Protocol) since 1992. It has a great number of shortcomings, most of which were fixed with the release of a new version of this protocol - HTTP/2. Its main distinguishing feature is implementation based on the technologies and algorithms of the SPDY protocol. In HTTP/2 were implemented following technologies: data compression of HTTP headers, HTTP/2 Server Push, pipelining of requests, fixing the head-of-line blocking problem in HTTP/1.x, multiplexing multiple requests over a single TCP connection. It also became possible to send data that has not yet been requested by the user, but with a high probability will be called soon. All this mechanisms reduce page loading delays and increase the reliability of the current connection.

This article discusses two technologies of the HTTP/2 protocol, which, presumably, will have the greatest impact on the speed of access to resources during the implementation of high-speed environment for accessing the university's e-learning platform.

The main goal of this work is analyzing various mechanisms of server requests to provide users the possibility of high-speed access to the university's e-learning platform. To achieve this goal, we investigated the possible ways to access the training platform, and analyzed the influence of multiplexing and prioritization on page loading speed. Upon the research, methods of forming flows using the HTTP/2 protocol were considered. It also were analyzed the benefits of multiplexing several requests in a single TCP connection over the HTTP/1 protocol, in which only multiple TCP connections could be used. The prioritization methods employed by the most popular browsers were investigated. In addition, the case of using default settings for browsers that do not support prioritization was considered.
The study and analysis shows that multiplexing and prioritization of requests really accelerate page loading, but the loading order is not always optimal. To accomplish this, it is preferred to use more complex priority schemes that are difficult to implement on the browser or server side.

Published: February 2023

As it is known, only specialists with high-level proficiency in informational culture and competence, are in demand in the intellectual labour market. A specialist of XXI century must be able to obtain, process and use information by means of computers, telecommunications and other tools. Therefore, nowadays we face the challenge of training a personality, who has skills to select the necessary information, systematize and acquire it at a high level. Such person needs to be current in the dramatically growing flow of information, and ready for life-long learning. As a result, under the rapid increase of informational flows and their large-scale use as a powerful means of communication, high priority is given to such challenges as educating intelligent people and implementing new technologies, based on the effective use of knowledge as a resource of the development of society. The paper focuses on the issues of building informational competence of higher school teachers for active use of information and telecommunication technologies, enabling them to work in the informational field more efficiently. The goal of the research is to identify approaches to building and enhancing sustainable informational competences of higher school teachers. To achieve this goal, the authors gave the definitions of such notions as 'professional competence' and 'informational competence'. The authors examine goals and objectives of the concept of economy and education development, which determine the need for personnel training to work in the sphere of digital economy in the Russian Federation. It is shown that due to their ability to work in the informational field, higher school teacher can significantly improve the level of students' training. It is assumed that the built basic informational competences, described in the paper, contribute to enhancing the level of higher school teacher professional competence.
AN E-LEARNING TOOL FOR MATHEMATICAL MODEL OF CHOLESTEROL HOMEOSTASIS DEPENDING ON DIET AND AGES
Authors: Ilea Mihai , Turnea Marius , Corciova Calin , Rotariu Mariana
Published: February 2023

The human health has many important aspects and the cholesterol regulation is one of them. The low-density lipoproteins cholesterol (LDL-C) transports plasma cholesterol (about 60%) and it is responsible by its depositing on arteries for atherosclerotic process, increasing the probability of cardiovascular events. High-density lipoproteins (HDL) can reduce this process by transport about 30% of plasma cholesterol. The balance is modified in the process of aging and depend also of other factors as diet, and physical exercises.
An educational tool is proposing that use basically two mathematical models: (1) a simple one by two compartment model proposed by Wona & Hrydziuszko that include an dietary term, and (2) a more complex one that include the mechanism of simulation of aging proposed by Mc Auley.
The values of parameters for both models are taken from literature and the user can modify them in order to test and simulated the models. The diet is modeled in the first model as an additive variable, and other variable are deduced from stability analysis and are assumed based on heuristic trials. In the second model, the mechanism of aging is simulated empirically (because the complete mechanism is not known yet) by increasing the LDL-C values and decreasing the number of hepatic LDL receptors (HLDLR) by decreasing the parameter that represents rate of synthesis.
The tool has a library with selected curves for (HDL-C) and (LDL-C) from different countries of the world by age and sex extracted from literature. In the future development, this information will be used to model and analytic additive function for (LDL-C) curve by fitting of parameters with experimental one in system of differential equations that models the cholesterol homeostasis.
A STUDY REGARDING THE ACQUISITION OF PHOTOPLETHYSMOGRAPIC SIGNAL USED IN DETERMINATION OF THE PRV PARAMETERS
Authors: Podaru Alexandru , David Valeriu
Published: February 2023

In this paper, two areas for collecting the photoplethysmographic signal were studied. The areas of interest we have considered are the index of the left hand and the lobe of the left ear. To record these signals we have created a portable system. To achieve this system we used 3 biological signal detection modules. With this system, three biological signals were recorded, namely, the electrocardiographic signal (ECG) acquired with the help of three electrodes, the PPG signal acquired from the left-hand index and the PPG signal acquired from the ear lobe. For the ECG signal, we used the AD8232 module, compatible with Arduino kits. For the photoplethysmographic signal, we used a pulse sensor, and for the other signal, we used an earlobe clip sensor, which generates a rectangular signal. The recordings of these signals were made on 16 subjects. All the recordings were made in the same way, with the subjects sitting on the chair. The signals were recorded simultaneously, using the same sampling frequency, to have a closer approximation in detecting the time interval between two cardiac cycles. From the recorded signals we determined the heart rate variability (HRV) parameters and the pulse rate variability (PRV) parameters from the two photoplethysmographic signals. With the data obtained we made 2 correlations as follows: a correlation between HRV parameters with PRV parameters determined from the left-hand index, and the second correlation was made between HRV parameters and PRV parameters determined from the signal acquired from the left earlobe, and the values obtained for both correlations are over 98%

Published: February 2023

The complexity of the training process, the increase of the demands in dealing with the training objectives, as well as the tendency to decrease the age of reaching the great performances in rhythmic gymnastics, are aspects that require the continuous improvement of the sports selection strategies. The current tendencies of the rhythmic gymnastics contest programs highlight exceptional performances, materialized in practice by higher difficulty technical executions with increased rates of reaction speed, the gymnast being forced to react quickly to stimuli, respectively to the movement of the object, for the success of the element or of the combination of elements. The reaction time has major implications in the efficiency of dealing with the specific technical elements, being especially important in the incipient stage of the formation of the skill for using the apparatus, respectively the I st stage of the sports training in the rhythmic gymnastics. The overall objective was to contribute to the improvement of the initial selection criteria in rhythmic gymnastics by objectively evaluating the complex reaction time to visual stimuli. The purpose of the study was to identify the importance and relevance of the TReaction Co software in the selection of gymnasts with real valences for practicing this sports field. The study was carried out on a sample of 30 gymnasts aged between 6 and 8 years old, in the sports hall of the UNEFS Bucharest. The testing was performed using the TReaction Co software, through which the complex reaction time was evaluated for the upper limbs -the dominant hand and the non-dominant hand. The results obtained by using the TReaction Co software were a useful step in completing the existing sources in the specialty literature of rhythmic gymnastics.
DICTIONARY CONSULTATION HABITS OF ROMANIAN LEARNERS OF ENGLISH AT UNIVERSITY LEVEL
Authors: Visan Ruxandra
Published: February 2023

The present paper focuses on the field of dictionary use, and examines frequency of dictionary consultation as well as dictionary preference among Romanian learners of English. Representative research on dictionary use includes Tomaszczyk (1979) and Wingate (2002) (see also Lew 2004 for an overview of the literature on dictionary consultation habits). While there has been significant research concerning dictionary use, the dictionary consultation habits of L1 Romanian speakers have been understudied (with few exceptions, see Vi?an 2018). Taking its cue from existing studies such as Atikins and Varantola (1998) which have found a correlation between dictionary use and proficiency level, the present paper focuses on a group of 214 Romanian students of EFL who major in English at the University of Bucharest, with two levels of English proficiency, namely B1 (95 students) and C1 (109 students). The paper shows that, as previous metalexicographers have underlined in studies focusing on foreign language learners, there appears to be a tendency among higher-proficiency learners to employ monolingual dictionaries more than bilingual dictionaries. This tendency occurs on the backdrop of a preference of the selected group of Romanian students, regardless of their level of proficiency, for monolingual dictionaries of English. The paper goes on to offer a detailed discussion of the context in which Romanian learners of English consult dictionaries at university level, attempting to identify the major factors which influence their lexicographical choices. The paper argues that the limited range of choice regarding bilingual dictionaries for Romanian learners of English (especially Romanian-English ones) can be seen as influencing the preference of Romanian students for monolingual dictionaries.

We live in an era of information explosion, of an accelerated and revolutionary technical progress, that is why it is imperative, obligatory to ask questions, to evaluate the risks, to modify methodologies, concepts and the creation of new learning situations. It is our responsibility to prepare the future, which today means the class of students, instilling in them models of attitudes and behaviors, transmitting to them the knowledge necessary for a world in a continuous change worldwide.
Software solutions in eLearning require the existence of a complex online teaching and learning system, through advanced technologies (laptops, smartphones, tablets, e-learning platforms, internet), providing access to different levels of study, depending on user needs.
Experimental mathematics continues to gain increasing importance in the engineering sciences, in this sense, computerization and simulation playing increasingly important roles, providing clarity and accuracy in the technique of the act of teaching-experimentation-evaluation.
The triangle Gergonne - Euler - Soddy, is a broad topic, which is why in this article we propose the analytical and graphical treatment of determining the coordinates of GERGONNE's point and the equations of parallel lines taken to the sides of the contact triangle, drawing the circle of ADAMS, and through Specialized software is developed a graphical application, highlighting their unique characteristics and properties in Euclidean geometry. Graphic modeling of the triangle ABC, the inscribed circle and its tangent points with the sides of the triangle, determining the coordinates of GERGONNE's point, drawing parallel lines with the sides of the contact triangle, drawing the circle of ADAMS was done with Graph 4.3 software.

Most people associate learning with the formal education provided by schools, high schools and universities; people expect to receive a "good education" from an early age. Generally speaking, it is true that formal learning, professional courses and training can maximize our potential, they can offer us satisfying and well-paid jobs, and they can amplify our success in the chosen career. However, formal education is not the only type of learning, many other opportunities can develop the knowledge and skills we need throughout life. Lifelong learning is based on creating and maintaining a positive attitude towards a lifelong education for both personal and professional development. Thus, the learning process is defined as an act that takes place throughout life, with or without our will, and involves choosing important information and continuously developing the gained knowledge. An animation is a tool that encourages the lifelong learning process and allows, regardless of age, the possibility to train and enhance learning through cognitive functions. This study aims to analyze the functionality of animation in the learning process, based on each age category. This paper presents the implications of animations and its areas of application. The amplitude of the way animations have started to monopolize fields related to media, gaming and science increases more and more, becoming more complex. In this context it is important to know the necessity of understanding the way animation is perceived in different fields and how useful it is she in transmitting a message. Animations in the learning process, are used to highlight different information from a wide range of topics.

Online learning is important in the process of acquiring information, but it also must be relevant in the process of socializing. Online learning gives students the opportunity to share and acquire knowledge through active cooperation. Even online, one must remember that cooperation through communication and exchange of ideas is an important part of the learning process. Online, students process the information individually or cooperatively through various strategies.
Taking into consideration that online interaction is equally important as academic knowledge acquirement, our present study aims to dwell on a selection of strategies by means of which students' interaction should be positive and constructive. The selection was made according to specific literature and to the models of practice provided by the teachers included in the project. The items brought under the lens were limited to technology access, creating small groups for school learning, peer reviewing, teacher's online support, guiding students to focus on online tasks and plan the work into a limited time schedule, applying a set of rules of online interaction behavioural patterns, obeying speaking and writing rules online, providing feedback for task accomplishments and online interaction etc. The sample involved in the research was based on volunteering and included 200 teachers from gymnasium and high school levels. Their experience in the didactic field varied from 1 to 21 years. The results of the research emphasized the importance of being acquainted with several strategies of supporting students' interaction in online learning activities so that the academic performance should be doubled by the strengthening of the social interaction.

The global pandemic obliged universities as a whole to move their educational activities onto online platforms. Many universities were not primed for such a sudden change, therefore their online teaching-learning methods progressed steadily. The current study is from a research series on online education and training, "The impact of Technology-mediated Interaction: Exploring New Channels for Effective Student-Lecturer Communications in Times of Disruption".
The study conducted a survey in which undergraduate and graduate students were asked to share their outlook on different aspects such as perceptions, preferences, and expectations of online education during the pandemic. The research goal was to study the impact of a pandemic on student's perceptions of online classroom versus in-person classroom teaching-learning.
The study applied qualitative and quantitative research methods to explore and analyze information. The research process was divided into two main phases: literature review, and survey study with closed and open-end questions. The study began with market research. First, exploratory research was used to discover suggestions, information, and understandings on a pandemic online learning culture. Second, exploratory research was used to define the characteristics of student pandemic perceptions online versus in-person learning.
The study received responses from 156 randomly selected students on various study levels. The vast majority of the students agreed that currently, online education is teaching- learning trend. Students positively evaluated the educational process, while indicating that the instructors were getting better with software platforms. Lastly, most of the students believe that online education is second to the in-person classroom experience. Additionally, the major concern identified by the students was the impact of a pandemic on their health and social lifestyles.
