3D MODELING FOR LEATHERGOODS

Author(s): Alina Iovan-Dragomir,Alexandra Bodoga / Language(s): English / Issue: 03/2021

Leather good products are intended to complete the outfit having an important aesthetic but also functional attributes. A distinct category of leather goods is represented by those products that are attached to the body. The positioning of these products in relation to the body involves a lot of design restrictions. One of the most significant restrictions is the ability not to affect the freedom of movement of the wearer. 3D modelling can be used for a good visualization of the model, on one hand, and adjusted it on different parts of the human body, on the other hand. Any product can be 3D modeled using specialized software and modeling techniques for video games. This paper presents the 3D modeling stages of a bum bag using modeling techniques for video games. The steps presented for creating the product in 3D represents a general "workflow". In order to complete the object, in working mode, multiple transition will be made from one program to another following specific steps for completion. They are used in different areas such as movies, games or 3D printers for toys. The program used are Zbrush > RizomUV > AutodeskMaya > SubstancePainter > Marmoset ToolBag3. In order to transform from 3D to 2D and pattern making was used MarvelousDesigner9 program. Using these programs can lead to student attractiveness and a better understanding of the steps of creating a leather good product. The objective of the paper was to present a creative and attractive way for students to improve their learning experience.

Author(s): Maximilian Nicolae,Radu Nicolae Pietraru,Andrei-Cristian Barbu,Andrei Tivgă / Language(s): English / Issue: 02/2021

The laboratory activities for an undergraduate course on digital design are normally developed around a physical platform. After the COVID19 prevention measures were established the activities had to move online, thus, the professors had to find some rapid solutions to preserve the initial goals of the laboratory. This article discusses the goals of such laboratory (in relation to the broad engineering domain), how are these goals fulfilled by a physical platform and what was the online solution that was developed to overcome the challenges. Furthermore, the opinions of students that were attending the both types of activities (physical and online) are presented.

A COMPARATIVE ANALYSIS OF THE SOFTWARE USED IN THE LABOR MARKET VS THE EDUCATIONAL SOFTWARE OF POSTUROLOGY USED IN THE TRAINING OF PHYSIOTHERAPY

Author(s): Catalin Ionite,Iustina Condurache / Language(s): English / Issue: 03/2020

The technological and informational explosion had a negative impact on human health by reducing the time allocated to movement in the daily activity. The simple activities such as newspaper picking, shopping, paying bills, etc., can now be done by a simple click from the computer or mobile devices. The technological development of the 21st century offers daily comfort, but it increases the time spent in static positions, favours the appearance of sedentary and producing changes in the posture of individuals. A correct body posture is a sign of good psycho-physical balance of the individual. Modifying it decreases the body's ability to fight against gravity, to oppose external forces, to balance itself during movements such as, to perform them etc. The consequence of these changes leads to the appearance of pathologies / diseases in all the segments of the body. The study aimed to identify in three databases of virtual libraries the devices and software used in the analysis of the individual's posture by the labour market and research, and then the identified information was compared with the software used by students from the specialization of Physiotherapy (Balneology, physical therapy and medical rehabilitation), from the Faculty of Biomedical Engineering, Iasi. After studying the specialized literature from three virtual libraries and identifying the devices and software used by the market specialists and comparing them with the devices and software used by the students within the specialization of Physiotherapy (Balneology, physical therapy and medical rehabilitation), we can say that the last class are using topical devices in posture analysis, but they do not depart from the classical methods of posture evaluation, while in the same time are making a comparison between the two generations.

A Discriminative Ontology for Future Selves

Author(s): Juraj Odorčák / Language(s): English / Issue: 4/2021

The article presents a critique of the commonly held assumption about the practical advantage of endurantism over perdurantism regarding the problem of future-directed self-concern of a person. The future-directed self-concern of a person crucially depends on the possibility of the right differentiation of diverging futures of distinct persons, therefore any theory of persistence that does not entail a special non-branching relation of a person to only their future self seems to be counterintuitive or unrealistic for practical purposes of personal persistence. I argue that this pragmatic rationale about future-directed self-concern is equally challenging for both theories of persistence. Moreover, I indicate, that both of these theories fall and stand on the practical feasibility of hidden ontological presuppositions about specific second-order notions of concerns of persons for their future.

A factual comparison of foreign (English) language acquisition factors in case of “Cserey-Goga” Technological High School’s monolingual and bilingual students during the COVID-19 period

Author(s): Csilla-Ibolya Sólyom / Language(s): English / Issue: 1/2021

This paper analyses the impact of online teaching on the process of foreign language – in my case English - acquisition as L2 or L3 and its factors for high school age students from two different language backgrounds. After providing a brief summary of the major language learning factors, transfer in language acquisition, and a short survey of the current Corona (COVID-19) pandemic, I examine the results of the questionnaire applied to two groups of high school students. The available data indicate that perhaps contrary to expectations the COVID-impact aspect was not the dominant element in the students’ response. I would highlight the comparison between two major groups of students: monolingual – in our case Romanian mother tongued students, and simultaneous bilingual – Hungarian mother tongued students who have already sequentially acquired the Romanian language as their first foreign language. In regards to the factors, I will briefly analyse motivation, attitude, cognitive style/personality, age, aptitude, teaching techniques and extensive use of digital media in English during the COVID-19 period. Literature suggests that those factors contribute more dominantly to second language acquisition and also present a varied dependence on behaviour towards the language, cognitive ability, and also the way they learn. I will consider the unusual circumstances presented by the COVID-19 pandemic, and attempt to define their impacting presence in second and third language acquisition processes.

A FREQUENCY-DOMAIN MODEL FOR E-LEARNING

Author(s): Brandusa Raileanu / Language(s): English / Issue: 02/2020

The characteristics of e-learning make it suitable to the Systems Theory approach. A system is an ensemble of entities which interact among themselves and with the exterior, in order to reach an objective. Clearly, e-learning integrates with this definition. The first trend in applying Systems Theory to e-learning was in lines of von Bertalanffy’s General Systems Theory. But being too general and descriptive, this approach did not develop concrete methods of being used to organizing and studying the e-learning process. The aim of this paper is to construct and apply a mathematical model for the e-learning process within the Systems and Control Theory, using both the state-space representation of systems and the frequency domain framework. This interdisciplinary approach between learning pedagogy, mathematics, statistics and engineering gives the possibility of following the evolution of the e-learning process, of evaluating, estimating, controlling, regulating and improving the results of the users of its tools. The paper introduces two linear time-invariant (LTI) systems, respectively continuous-time and discrete-time models. Their inputs correspond to different e-learning methods and the outputs are the various forms of examination and testing. Using Laplace transformation and z-transformation, one obtains the frequency-domain representation by transfer matrices of both models. Suitable programs are created, which are based on the Control Systems Toolbox of the Matlab software. This approach provides very simple methods of estimating the concrete results of different e-learning strategies and of choosing optimal policies. In the paper, this e-learning model is applied to the study of foreign languages, in which the state variables correspond to the four main skills, reading, writing, listening and speaking. Similar applications can be developed for various engineering courses. An example is provided, based upon a sampling and statistical study of the behaviour of a group of students from the Faculty of Applied Sciences, University Politehnica of Bucharest.

A FUZZY MEASLES EPIDEMIC MODEL, GENERALIZED APPROACH IN A FUZZY ARITHMETIC FRAMEWORK

Author(s): Dragos Arotaritei,Andrei Gheorghita,Mariana Rotariu,Mihai Ilea / Language(s): English / Issue: 03/2020

The epidemiological models modelled by a system of differential equation depending of time are useful to model the dynamic of the epidemic along with future prediction of the spread of disease. Also, the dynamic model help to better understand the equilibrium point(s) and when is the case the optimal strategy for vaccination (where the vaccination is possible and a vaccine exists) or treatments allow eventually with other measures (as social education in some cases). One of the most studied models that can apply for many diseases that are described by compartmental model is the SEIR model: malaria, Ebola, measles, etc. There are few proposals for simulation tools of epidemic models but all are for crisp cases. In this paper we propose an educational tool for simulation of fuzzy SEIR model applicable to measles dynamics where all the coefficients from model can be crisp numbers of fuzzy numbers (triangular, trapezoidal or Gaussian) with corresponding graph display of epidemic dynamics. Moreover, in the cases when two coefficients are in the same differential equation, a proposal to solve to problem is made in the fuzzy arithmetic network. An additional module is used to construct a more extended fuzzy epidemiologic model, with additional compartment, e.g. SEIRS, in a friendly manner by a user interface for builder model of differential equations. The tool has a library with predefined models and an option to select to parameters in order to have an asymptotic stable solution. The user can select the graphs to be displayed on the common window or in a separated window with zooming possibility to evaluate better the evolution of dynamic system.

A hypertext, az online kommunikációs csatornák és a digitálismédia-platformok mint az oktatás új otthonai

Author(s): Zoltán Szűts / Language(s): Hungarian / Issue: 4/2020

The digital turn in pedagogy is based on both a communication and a text-centric revolution. This paper summarizes how an interactive text gives a new home to education. It, obeys the laws of the new networks, is inherently convergent, combines image, video, and sound while supports not only interactivity but also co-creation, and thus the user becomes a creator of content, that is, a prosumer. As a result of the integration of online communication and media processes into the subsystems of our world, educational institutions have begun to introduce and operate e-learning environments. Digital pedagogy is currently based on cloud-based, web 2.0 online communication and media platforms, and mobile applications. There are many ways to categorize these platforms. A valid approach is to divide based on access or the number of participants in learning. Considering all possible approaches, the author finally decided to group and examine the applications based on the communication functions they perform, while also addressing their elements based on hypertextuality.

A MULTIDIMENSIONAL APPROACH TO CYBERSECURITY FOR CRITICAL INFRASTRUCTURES

Author(s): Petrișor Pătrașcu / Language(s): English / Issue: 01/2020

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.

A PERSPECTIVE OF STUDENTS ON FEEDBACK IN ONLINE EDUCATION

Author(s): Daniela Căprioară,Virgil Frunză / Language(s): English / Issue: 01/2021

Feedback is undoubtedly a very important element in the general structure of the training and learning process, the peremptory proof of importance being the principle of feedback or reverse connection, listed in the current pedagogical or didactic literature. Efficient use of feedback in teaching-learning activity is conditioned by a series of variables, among which are found the elements of specificity, the functions of feedback, its forms and, last but not least, the concrete means by which it can be achieved. The pandemic context generates the problem of a paradigm shift in terms of feedback management, a rethinking and a repositioning of it in the general configuration of the training and learning process. In other words, they need to be reviewed. The main question that formed the basis of this study is: What is the students' perception of the feedback, both in terms of personal experience, but also that of the training specialist for the teaching profession? To formulate an answer to this question, a questionnaire was applied to a group of 80 students from the Pedagogy of Primary and Preschool Education program. Years 2 and 3 were selected, for two reasons: on the one hand, to have a psycho-pedagogical knowledge base that would allow them to formulate pertinent opinions and, on the other hand, to have a comparative reference, having in view that they have completed at least one semester of university studies in face-to-face education. The results show that students' perceptions of feedback in online education are relatively different.

A PLATFORM TO PROMOTE A MORE ACTIVE LIFESTYLE BETWEEN STUDENTS

Author(s): Imad Alex Awada,Irina Mocanu / Language(s): English / Issue: 03/2020

Due to the current lifestyle, people in general and adolescents in particular are not physically active enough which put at risk their health. Immediate actions are needed to promote a more active lifestyle. This paper introduces a platform that aims to encourage students to have a more active life. The platform suggests for each user to perform specific physical activities/exercises based on the physical activities that the user had during the day, the duration of the sleep and his/her profile (preferences, performance history) as well as some health parameters (heart rate, blood pressure, weight). All these tasks are realized through a game with an avatar that is controlled by the user through the execution of the different physical exercises/activities in real life (e.g. the avatar is placed in an environment to collect different objects; to do that, the user will have to jump and to run in real life). The exercises performed by the user are acquired using an RGB camera. Images are processed and the skeleton of the user is obtained using the OpenPose library. To increase motivation, the platform gives different rewards (e.g. more points) for executing physical tasks and suggests some collective physical activities based on the profile of each user. The platform is multilingual, it supports Romanian and English languages, with the possibility to extend it to other languages. The platform integrates a multimodal interface that enables the users to interact through voice and touch-based commands as well as touch-free gestures. During the execution of a physical exercise, the platform tracks the performance of the user. The platform sends visual and phonetic notifications to the users’ phones to suggest the execution of some physical activities/exercises.

A Possible Contribution of Live Electronics to Modern Education / O posibilă contribuție a aplicațiilor electronice live la educația modernă

Author(s): Mihai Popean / Language(s): English,Romanian / Issue: 1/2021

Musical improvisation is as much a form of art as it is a form of education with great potential for transfer. Although associated usually with jazz music, improvisation has a long and unbroken history that can be traced throughout the entire music history. The classically-trained students do not receive education in improvisation, it is not part of the classical music curriculum, the educators themselves do not have such training and are not comfortable improvising and therefore teaching it. However, students can greatly benefit from this type of training by greatly enhancing their technique and performing skills and also by developing a set of other important skills such as creativity, calculated risk-taking, flexibility of mind, capacity to notice opportunities, greater awareness of their environment, intra- and interpersonal skills, enhanced communication abilities and more. One solution that would address teachers’ lack of improvisational skills and students’ need for such educational opportunity is for educators to learn basic visual programming in order to create applications for improvisation that involve live electronics and deploy them in classroom or other educational situations.

A PROPOSAL FOR A SIMULATOR FOR RESPIRATORY CONTROL SYSTEM, TOWARD A LEARNING TOOL FOR BIOMEDICAL ENGINEERING STUDENTS

Author(s): Calin Corciovă,Andrei Gheorghita,Robert Fuior,Marius Turnea / Language(s): English / Issue: 03/2020

There are only few non-commercial models that models the cardio-respiratory system that take into account the main interconnected units involved in respiration (“PNEUMA” and “Respilab”). The proposal for respiratory control presented in this paper follows the Tahrani’s model with options in GUI (Graphical User Interface) more suitable biomedical engineering students that have knowledge about modeling and simulation and numerical methods for differential equations. The obstructive diseases as hypercapnia and hypoxia are simulated by modeling the forces (stimulus) as consequences of the modification of values of inspiratory gas partial pressures. The parameters of models can be changed in an interactive mode. The user has the possibility to select which variable to be displayed and also parameters for integration of system of differential equations. The model has a PI integrator, and as sequel, a short tutorial about PID (Proportional-Integrative-Derivative) controllers is available in help section. The calculation of respiratory frequency has three predefined models: Otis’ equation, Mead’s equation and Widdicombe’s equation. A user defined option is possible give a by constructor module that afford the select a linear combination of the predefined models or to create a completely new model with the save option for future use. The implementation uses the Matlab/Simulink tool with transparent view of the model schemas and subschema’s avoiding the usage of .jar files from Java environment. The working version can provide a standalone working model directly from Matlab implementation using a suitable compiler. This educational software is constructed in a modular form; other modules including visualization of waveforms can be improved with no substantial effort in the future.

A SIMPLE EDUCATIONAL TOOL FOR MATHEMATICAL MODEL OF SKIN ABSORPTION FOR BIOMEDICAL ENGINEERING STUDENTS

Author(s): Mariana Rotariu,Mihai Ilea,Calin Corciovă / Language(s): English / Issue: 03/2020

Biomedical Engineering (BME) is different from other engineering or medical areas, in the sense that the results are obtained usually by experimental procedures and the simulation using mathematical approaches are familiar to them without a very deep knowledge of medical subjects specific to physicians. The tool proposes one and two compartment models for mathematical model of skin absorption selected from models in literature. The compartments models are described by system of differential equations that are solved by numerical methods. The user has the possibility to select the model and the parameters of the models (the Graphical User Interface - GUI) is automatically updated according the selected model along with a graphical image of compartments and the variables that are assigned to interaction among compartments. The parameter for simulation (the solving of system of differential equations) are adjusted optimally according to selected model but they can be also modified by the user in order to test the sensitivity of the models to different value of parameters. The dosage substrate and/or inhibitors can be calculated by user using this tool. The constant of permeability and diffusion, deduced by experimental data, can be included and saved for future use using a selection panel. The implementation is made as a Matlab application with a GUI designed as a friendly user interface. The graphic of evolution of variable are displayed in a window, and the user has the possibility to select the group of variables to be visualized. The tool is accompanied by a small user's manual with a set of practical tests in the form of laboratories in order to improve the e-learning process. A more concise form of the mathematical model can be used by students in Balneo-Physio-Kinetotherapy (BFKT) by simulated be the Sulphur absorption by skin in sludge therapy.

A Study of Effects of E-Learning Based Exploratory Education on Students’ Self-Efficacy and Interpersonal Relationship

Author(s): Lingke KONG,Zhenlong CHU,You LI / Language(s): English / Issue: 72/2021

Under constant education reform to cultivate students with transferable skills, it is necessary to effectively release excessive competition for school admission and guide normal teaching and balanced development of five ways of life. By re-positioning book knowledge as footprints commonly accumulated by humans, it might be able to recover current rigid education. Students should not be restrained from formal education, but should positively cultivate learning autonomy aiming at living to successfully seek for goals and ideal. Taking a university in Fujian Province as the empirical object, total 214 students are preceded the 15-week e-learning based exploratory education experiment (3 hours per week for total 45 hours). The research results show that exploratory education would affect self-efficacy, exploratory education would affect interpersonal relationship, and self-efficacy reveals significantly positive effects on interpersonal relationship. According to the results to propose suggestions, it is expected to help students discuss, communicate, establish goals, solve problems, and generate trust in the interaction process in learning activities as well as connect specific experience in activities with life experience, transfer and generate meanings, encourage adventure and self-challenge, self-awareness, and finally discover innovative thinking and new potential to generate the natural development for learning and change.

A STUDY REGARDING THE ACQUISITION OF PHOTOPLETHYSMOGRAPIC SIGNAL USED IN DETERMINATION OF THE PRV PARAMETERS

Author(s): Alexandru Constantin Podaru,Valeriu David / Language(s): English / Issue: 03/2020

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%.

A USE CASE FOR ARITHMETIC AUTO-GENERATIVE LEARNING OBJECTS IN PANDEMIC

Author(s): Felicia-Mirabela Costea,Ciprian-Bogdan Chirilă,Vladimir-Ioan Crețu / Language(s): English / Issue: 02/2021

During the COVID-19 pandemic the educational processes were interrupted in most of the countries in the world. Governments switched from face-to-face education to online sessions using learning management systems and video and audio communication tools. Pupils connect to online classes using laptops, tablets, and sometimes using mobile phones. These methods are exhausting and tiring for the pupils, so a limit of half of the time used in the face-to-face classes was set for the online classes. This approach restricts the number of hours a tutor works directly with their students. Probably the theoretical aspects are presented to the class and then a limited set of examples are given. Normally, a tutor should check individually the activity of each pupil, but this is not possible because of the time restrictions. In this context learning objects and more specifically auto-generative learning objects complements the tutors by: i) proposing exercises to pupils; ii) grading automatically the pupil answers; and iii) offering feedbacks on the given answers. In this sense, we applied the proposed approach on a group of 8th grade, 50 pupils, at the Arithmetic disciplines focusing on intervals and inequations. We created nine auto-generative learning objects where reunion, intersection, the difference of intervals was exercised. We modeled learning objects for five types of inequations. The study shows that the proposed method's effectiveness is very close to the classic evaluation method. We collected the opinions of pupils in a satisfaction questionnaire about using auto-generative learning objects and the results state that 92% of pupils liked them.
