In the early 90's, and especially in some American universities, with the emergence of virtual reality, virtual environments and their manipulation began to be implemented, achieving important advances that have led to improvements in research through changes in the perception of the subject, modeling, communication processes and the development of 3D virtual classrooms. These advances have led to the metaverse, as an environment where humans interact socially as avatars, and especially its application in the world of education in the fields of entertainment, tele-education, educational research, learning environments, etc. According to technologists, this year will separate the thinkers from the builders, and then the technical advances of the last few years will produce the first steps this year in making the metaverse a reality. Advances will largely be attributed to ever-better graphics processing units (GPUs), photorealistic 3D engines, faster content generation through volumetric video and artificial intelligence, the increasing prevalence of cloud computing and 5G, as well as a more sophisticated and better understood blockchain infrastructure. But from a human experience perspective, one development stands out above all others: extended reality (XR) technologies. These include virtual reality (VR), augmented reality (AR) and brain-computer interfaces (BCI), which together are positioned as the next computing platforms in their own right.

The subject of this study is the phenomenon of the success of an electronic program (Microsoft-Excel®) for the dam maintenance database. Project improvement includes three phases with a duration of 2 years. The current Excel programming is free, in contrast to specialized software, which costs hundreds of thousands of dollars. More than 6,000 cells were programmed with many smart logarithmic equations. The purpose of this study is to explain, in a practical and theoretical framework, the reasons that cause the distinguished project results (reduction of the completion of maintenance reports from months to 5–10 working days) with low-cost efficiency. Therefore, this leads to increasing the agility of maintenance work fulfilments (effectiveness). Particularly, 11 criteria were designed to compare the status of the project; before and after; improvement. Theoretically, this study adopted the case-study research approach. It aims at setting enablers (actions) that lead to a specific outcome (theory - model building) of the current practice. The study sample was represented by the project team themselves. As a result, the study model (theory) estimated six elements (variables). Generally, the reasons for the success included three elements: technical, managerial and personal factor. These factors led the maintenance project to achieve high efficiency, accuracy and effectiveness. As a comprehensive recommendation, if any global construction institution (such as the Dams Department) intends to implement a similar e-project, its focus should not be limited to the electronic aspect; rather, the managerial and personal aspect should be the focus. In addition, this e-project is a ready base for an optimized technological platform.

In the nitrogen fertilizer industry, the nitrogen content of chemical fertilizers is an important parameter that determines its physical strength, storage capacity and storage life. The production variables that determine this physical parameter, which is characterized as degradation and caking, can be expressed as the characteristics that determine the course of the chemical process. Although there are improvements in reaction conditions to solve the caking problem, the cost problem of the manufacturer limits the processing conditions. For this reason, in order to minimize the cost problem in any nitrogen fertilizer production process, the analysis of working conditions and the development of quality management systems accordingly constitute the focus of the manufacturer. In this study, within the scope of lean production, regression analysis of the 6-sigma quality method system was performed, the process parameters during the production were analyzed, the optimum conditions were determined and the effect on the production cost was investigated by comparing with the current production conditions.

Recently, there is an alarming increase in the number of deaths resulting from late rescue of drowning personnel falling overboard. Most mechanisms deployed are faced with the inability to detect the exact location of the drowning person especially when completely submerged in water. This paper therefore describes the development of a smart rescue communication system for drowning personnel. The developed system considered two major activities involved in drowning: the first scenario considers when the individual is completely submerged in water and the second; when the victim is struggling to survive. Thus, water and vibration sensors are useful input devices in actualizing the work. Arduino microcontroller was also used for the control system mechanism. For drowning and drowned situations which is detected and specified by the readings from the relevant sensors, an SMS (short message system) alert is communicated to the rescue personnel’s phone indicating that there is an emergency. The exact location of the man overboard is also indicated in the SMS with the aid of the global positioning system (GPS) module. The SMS is sent at specified intervals to increase awareness of the current situation to aid fast rescue operation. The prototype is designed to be a wearable device.

Discussions about the extent of integration of adolescent refugees as well as integrating displaced people ‘correctly’ in the respective education system of the target country have long been held about. Since crisis caused by, for example, war or the Covid-19 pandemic increase the numbers of refugees all over the world, a high number of displaced people suffer from experienced traumas and might therefore be impaired in participating in curricular education. For this study, the observation of three adolescent refugees who attend different sports classes, thus being encompassed by variable social settings, has been at the center of attention for one semester. To ensure data variety, principals, PE teachers, refugee students, ‘regular’ students have been interviewed, respectively. The analysis revealed that huge differences in terms of adaptation as well as impairment could be observed among the participating adolescent refugees. While one of the refugee students easily adapted among the observed manifestations (non-)verbal communication, social form, behavioral strategies and potentials of physical education, the other adolescent refugee displayed severe impairment in all of the manifestations mentioned above; hence, experienced traumata experienced before, during or after flight require newly arriving students being psychologically examined and monitored.

A map α: Xn→Xn is called a transformation on Xn We call α a signed transformation if α: Xn→X*n Let Tn and T˜n be the sets of full and signed full transformations on Xn respectively. The work, w(α) performed by a transformation α is defined as the sum of all the distances |i-iα| for each i ϵ dom(α) In this paper, we present a range for the values of w(α) for all α ϵ Tn. Further, we characterize elements of T˜n that attain minimum and maximum works and provide formulas for the values of these minimum and maximum.

Distributed denial of service (DDoS) attack is generally known as one of the most significant threats to the internet of things (IoT). Current detection technologies of DDoS attacks are not adequate for IoT systems because of the peculiar features of IoT such as resource constraint nodes, specific network architecture, and specific network protocols. Providing adequate DDoS attacks detection systems to IoT, however, becomes a necessity since IoT is ubiquitous. This study hence developed a deep learning-based model for detecting DDoS in IoT, while considering its peculiarities. The proposed deep learning-based model was formulated using a deep Gaussian-Bernoulli restricted Boltzmann machine (DBM) because of its capability to learn high-level features from input following the unsupervised approach and its ability to manage real-time data that is common in the IoT network. Furthermore, the SoftMax regression was used for classification. The accuracy of the proposed model on the network socket layer-knowledge discovery in databases was obtained as 93.52%. The outcome of the study shows that the proposed DBM can efficiently detect DDoS attacks in IoT.

This study aimed to identify the psychological and social effects of divorce on children from their viewpoint, and to achieve the aim of the study A questionnaire was developed consisting of (17) items that were distributed to a sample of (100) children of the divorced, and they were randomly selected. The researchers used the descriptive and analytical method for the study. The study concluded that feeling fear and anxiety about the future and the accumulation of worries and diseases is one of the most psychological effects that children of divorced men are exposed to, and it leads the individual to a feeling of inferiority and lack of self-esteem. While the most social factors affecting the members of the study sample were that divorce leads children to bad company due to poor family control over them. Then society viewed them as an inferior view that they are not socially qualified. The results of the study also showed that there were no statistically significant differences attributed to the age or gender variable, while statistically significant differences appeared due to the scientific qualification variable.
