Privacy Protection of Wireless Sensor Networks from the Perspective of Big Data

With the advent of the era of big data, the relevant technical standards of wireless sensor networks are becoming more and more perfect, so the information security of wireless sensor networks will also attract increasing attention. Because once the information secret of the wireless sensor network is leaked, it will bring huge damage to the entire Internet environment, and even cause the entire Internet to collapse. As a result, the privacy security problem in sensor networks has become an urgent problem to be solved. This paper aims to study the privacy protection of wireless sensor networks from the perspective of big data. Taking data privacy protection as an example, it proposes based on the analysis of the characteristics of wireless sensor networks, the application fields of wireless sensors, the classification of data aggregation technologies, and the CPDA scheme. An improved data privacy protection scheme is proposed, and simulation experiments are carried out on it. The experimental results show that the privacy of the method used in this paper is better than that of the CPDA method, and the probability of the lock being exposed increases, and its privacy is better than that of CPDA.
Introduction to a Special Session on Hardware Security for Smart Society

In the smart society, individualized and comprehensive services, which collect a wide variety of physical/biological data and utilize the knowledge acquired from them, are expected in applications with the real world, such as automobiles, industrial and household robots, and tailor-made medicines. On the other hand, security has become an inseparable issue in utilizing and expanding such next generation services. In particular, data protection by cryptography is essential for services that handle data containing sensitive and/or private information. However, when encrypted data is queried or processed, it usually needs to be decrypted once. It is difficult to completely prevent data stealing and/or tampering by attackers or malicious parties.
IMMERSIVE DATA ANALYTICS FOR ENHANCING ORGANISATIONAL KNOWLEDGE TRANSFER PROCESSES THROUGH A CUSTOM DEVELOPED VIRTUAL REALITY FRAMEWORK

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.
TOWARD TO AUTOMATION THE EVALUATION OF STUDENTS MINDMAPS QUALITY

Mind mapping is the well-known approach for visualization the complex topics in education. In [1] we propose the synthesis of active and passive ways for using mind maps in education practice. By this way we need construct the software tool for building mind maps with special requirements. First of all, this is the limitations for the set of mind map nodes. Student will select for placement on mind map only nodes from the set of items from dictionary of current lesson topic. And may be from the course main glossary. This limitation is necessary for automatic pre-evaluation the quality of student's mind maps. The value of quality will calculate on the base of the measurement of distance between original teacher's and student's mind maps. So we need to make the three solutions: 1. Haw to find the set of termins for the actual topic? Glossary is the one of typical course resource in the learning management system Moodle. In [2] we present the simple tool "wordstat 2.0" for term selections from the course content documents set. 2. Provide the easy tool for mind mapping. We assume that the fast solution can be reached on the basis of modifying the open source software. The allowable opportunity is about using text-only environment, like Text2MindMap online tool. 3. Evaluation the maps structure (dis)similarities. The mind map has the graph structure. So the mind maps quality measurement can be estimate via comparison the graph structure similarities. It is well known task. There is no problem for getting the graph structure from outline text or from XML mind map file. 1. Dubinsky, A. (2019) Mind maps for education.

It is aimed to contribute to the field of strategic management by comparing the values that emerged as a result of this study. In summary, the aim of the research is to support the idea that by using the quantitative evolution results of strategic plans and qualitative evolution results of individuals cognitive maps for the same goal make it possible to contribute to strategic development of organizations.
LEARNING ABOUT INTERACTIONS AND EMOTIONAL SUPPORT THROUGH CHATBOTS

In the contemporary period, social life is strongly mediated by digital technology, which influences both the knowledge of one's own person and the knowledge of others. Digital can facilitate inter-human communication, increase professional efficiency, improve the quality of life or even change the perspective on society. Digital instruments started to be used also as "emotionally intelligent bots" which might help individuals building emotional resilience, promising "no judging", "privacy", "reflective space" and being "your 4 am friend". Human - non-human relationship became a reality through friendly interactions and learning processes in both direction: from non-human to human and from human to non-human. How is the human - non-human interaction constructed through chatbots? How is the human portrayed in chatbots? How is the non-human portrayed in chatbots? How are learning processes build through emotional support chatbots? These are some of the questions which will be addressed through this paper. This paper aims to analyse the learning role of the emotional support chatbots focusing on the learning processes and the knowledge produced through the human - non-human interaction. In the first part of the paper, I will summarize a literature review of the main articles relevant for this theme. The second part of the paper will include a review of the existing apps promising emotional support and a study case on 2 of the apps following three objectives: (1) understanding the interaction built between human and chatbot, (2) examining the learning processes enhanced by the chatbots, and (3) analyzing types of knowledge produced through the interaction and the learning processes.
THE COMPARISON OF THE RESULTS OF THE CORRESPONDENCE AND THE FULL-TIME TRAINING.

Based on statistics members of the correspondence training are mostly people who are working, so in most cases this decision for them is forced. The least of them choose this because of personal reasons (for example: unfinished full-time trainings, individual researches, living far away from school, etc.). Nowadays most of the universities offer classic full time-training as well as correspondence trainings. There is no difference between the diploma earned with full-time training and correspondence training. Compared to the full-time training there are less members of the correspondence training, so the lecturers can attend to somebody more individually. Most universities require from students in correspondence training to complete internships where they gain experience. Based on their experience, they prepare their diploma works. It often happens that correspondence training provides less valuable education than full-time education. However, this is already denied by the trainers, and employers do not raise this issue. Both type of trainings has valuable people with different benefits. Correspondents usually stand out for their purposefulness and life experience, which makes them unique not only at university but also later in the workplace. Because contact hours are on Friday afternoons and weekends, they are usually blocked. In this article we present the results of a research where we examine the exam results of correspondents and full-time students for several years. In the research we analyze the exam results of hundreds of students from which we draw conclusions. We want to show you what the students of the correspondence training are better and where their results are worse.
INCLUSIVE EDUCATION OF EDUCATORS OF EDUCATIONAL INSTITUTIONS

The modern education system puts forward new requirements for the education and upbringing of children with special health opportunities. Inclusion provides an opportunity for children with HIA to receive education, involves a rethinking of society's attitude towards children with HIA, recognition of their rights equal to other children. Also, inclusion is the full development and self-realization of children with disabilities and the development of social skills. To solve the tasks set by the government and society, there is a need for psychological and pedagogical education of inclusive education both at the level of schools and educational institutions, and in the general public. The main role in the education of children with disabilities is given to teachers who need to be competently included in the process of training and upbringing of all participants in the process, as well as to ensure a high-quality educational process organized taking into account the individual capabilities of everyone. In addition, the teacher should know the specifics of the development of children with disabilities, their motives and needs, to draw up a competent adapted educational program, which will be the basis for the educational process of children. In addition to the teacher, the process of education and education includes specialists in the support of the educational process, namely: a teacher-psychologist, a defectologist and a speech therapist, the purpose of which is to accompany children with disabilities, their socialization, correction and development of deficits. They, including the teacher-psychologist, need to build correctional and developmental work with children based on their knowledge and experience, as well as on the experience of other psychologists and scientists working in this area.
High-Speed Semantic Segmentation Based on Dual-Path Feature Fusion Codec Structure

To address the problem of large parameters and slow segmentation speed in high-precision image semantic segmentation, a semantic segmentation deep learning-based model is proposed. By encoding both semantic and spatial paths, the model is able to fuse different feature information and compensate the disadvantage that it is difficult to combine spatial and semantic information, so that the feature map can be convolved efficiently. Furthermore, this model decoder merges high-level semantic information and low-level spatial information, to effectively compensate for the loss of feature information via the down-sampling operation during encoding. The experimental results on the Cityscapes and Camvid datasets show that the parameter of the model is only 3.91×10<sup>6</sup>, with mean intersection over union of 67.7% and 65.8% on the two datasets respectively. Also, the segmentation speeds are 111 FPS and 86 FPS, respectively. Compared with some similar models, the proposed model has fewer parameters and higher accuracy, and its segmentation speed significantly exceeds the minimum frames per second (24 FPS) required for real-time semantic segmentation.
EVALUATION OF THE SITUATIONS OF INTERNATIONAL STUDENTS IN THE DORMITORIES IN THE ONLINE EDUCATION MODEL DURING THE PANDEMIC PROCESS

Covid 19 as pandemic condition has affected the way of life in societies. International students whose were away from countries and living in dormitories have affected in both social and educational aspects. In the near future, it is predicted that online education will become the main ground of education instead of being an alternative or a support function for face-to-face learning, The lessons learned from the early widespread digital learning experience, which has been passed with a rapid adaptation due to the COVID-19 pandemic. Online education experiences of international students were examined in the research study. In this respect, this research aims to determine situation of international students in pandemic process. Qualitative research was employed in the research that online interview form was conducted to collect data. This research revealed that most the students are satisfied from food support or food packages, technical support for educational purposes, free hospital service by the university, financial support from various private and public organizations as well as psychological support for students living in the dormitories. Some of the students believed that face-to-face education is more effective than online education. But some of them acknowledged that online education was the best option to avoid loss of education during the pandemic. International students underlined that they were mostly informed in the dormitories and the cafeterias on protection from COVID-19 through brochures, oral seminars or via the Internet. It is concluded that socialization and education services of international students have done regarding to the higher education responsibilities.
E-LEARNING IN MANIPULATIVE GEOMETRY TEACHING

the beginning of 2020, COVID-19 pandemic changed the way of teaching methods at universities in Slovakia. In a very short time, the traditional lectures had to be replaced by on-line lessons, often without any preparation of teachers to such a form of lectures. Although teachers were able to teach at the faculty, the students watched their lessons in the comfort of their homes. In the present paper, we focus on the impact of COVID-19 pandemic on the level of students' knowledge from the subject Manipulative Geometry. We analyse the results of the experiment, which was conducted on a sample of 249 students of the Pre-School and Elementary Pedagogy at Trnava University, Faculty of Education. We compare the results of three groups of students: external students taught by a blended learning, daily students taught by a combination of video-lessons and e-learning course, and external students taught by a combination of video-lessons and e-learning course. The way of teaching of the second and the third group was influenced by a ban of a face-to-face lessons as a result of the pandemic situation in Slovakia. Using statistical hypothesis testing, we prove that there is no significant difference in the results of the groups in the final test, from which follows that the restrictions connected with the COVID-19 had no negative impact on the level of students' knowledge. Thus, the results of our research reveal that thanks to a proper use of digital technologies it is possible to eliminate the negative effect of the ban of face-to-face lessons.
COMPARATIVE ANALYSIS BETWEEN MAINSTREAM SOFTWARE DEVELOPMENT METHODOLOGIES

A lot of companies lost money because they chose the wrong software development methodology. For example, Knight Capital Group lost $440 million in 30 minutes when its trading software flooded the market with erratic trades. The bug was the result of a faulty development cycle that did not account for communication about possible errors and adequate testing before the product was launched. That's why choosing the right system and style of management is the key to successful software development. Today, we have many approaches, and they all have their advantages and disadvantages. It's a difficult and crucial task for future or ongoing projects to choose the most suitable strategy as well as define objectives, budget, and deadlines. The following article analyses the main differences and characteristics of the most popular software development methodologies with emphasis on performance, meeting deadlines, and team morale. The results are synthesized from a survey completed by more than 100 IT&amp;C domain professionals based on their expertise and will be interpreted using a statistical approach. The objective of this study is to determine which methodologies tend to produce the best results regarding the team's main goals. It was targeted a wide array of IT professionals, emphasizing their experience level in the industry, regarding both the time in which they applied a certain methodology to a project and how applying it affected the project's success. Through this research, we hope to provide a clearer view of the outcome of the usage of different methodologies in various endeavors, so that, before starting a software development project, the best way for organizing it will be chosen.
E-LEARNING - ALTERNATIVE OR NEED?

The pandemic caused by the new Covid-19 imposed at international level a series of measures to protect and limit human interaction, measures that also had effects in the education system. The starting point of the analysis is the fact that previously alternative methods were applied in the educational process that did not require physical attendance at courses. In front of the new challanges, states have been forced to continue and develop these methods and, at the same time, to identify new ones so that the educational process can be completed with at least the same expected effects. This article aims to analyze the effects of the pandemic on the educational process and how to implement the lessons identified during this period to streamline the educational process in the future when the effects of the pandemic will cease. For this, applying heuristic research methods, both classical and unconventional, we analyzed the different approaches of some states and proposed uniformity measures at regional level to obtain maximum effects in the educational process. Documentary research and content analysis allowed us highlight some positive aspects of the application of alternative methods. Moreover, the comparative analysis and the study of the actions undertaken allowed the identification of the need to combine in the future the classic methods of conducting the educational process with the specific e-learning ones. This could be the key to a more efficient path in terms of improving and achieving the highest possible results in the education system with the minimum use of the necessary resources.
VIRTUAL CLASSROOMS - SOME CHALLENGES AND SOLUTIONS

The outbreak of the SARS-CoV-2 epidemic has upset the traditional Romanian pattern for institutional education. When the government declared a state of emergency this spring and instituted a quarantine and restrictions in the entire country, subsequently only in some areas and then again in the whole country, schooling took a severe blow as pupils and students were no longer able to physically attend classes at their regular schools or universities. Most teachers, learners and even parents were forced to quickly update their methods of communication, to acquire smart devices as well as pertinent knowledge on how to work with said devices. This study focuses on some of the challenges encountered by its author when interacting with BA and MA students from 'Carol I' National Defence University in virtual classrooms and it also supplies some of the communication strategies which have proven useful in influencing participants to actively engage in activities, no matter if these were individual, pair or group tasks. Some communicative strategies which the author has employed as countermeasures in fighting students' boredom during online classes come from the traditional face-to-face interaction between students and teachers. In this sense, questions have proven to be effective tools, whichever their type may be - rhetorical, action or discussion questions. A second strategy has been the activation and reactivation of Area 47 of the brain by stirring students' curiosity and interest. Therefore, this paper initially presents the three types of questions with specific examples and results of their use in virtual classrooms and subsequently it looks into ways of activating Area 47 and the benefits thereof. To show their efficiency, a study was undertaken which is exploratory and discusses the data obtained from applying the abovementioned communicative strategies on 17 BA and 9 MA students over a period of six weeks.
