: Substantial research has been conducted to compare web servers or to compare databases, but very limited research combines the two. Node.js and Golang (Go) are popular platforms for both web and mobile application back-ends, whereas MySQL and Go are among the best open source databases with different characters. Using MySQL and MongoDB as databases, this study aims to compare the performance of Go and Node.js as web applications back-end regarding response time, CPU utilization, and memory usage. To simulate the actual web server workload, the flow of data traffic on the server follows the Poisson distribution. The result shows that the combination of Go and MySQL is superior in CPU utilization and memory usage, while the Node.js and MySQL combination is superior in response time.

Since February 2020, when the first case of infection with SARS COV-2 virus appeared in Romania, the evolution of COVID-19 pandemic continues to have an ascending allure, reaching in September 2020 a second wave of infections as expected. In order to understand the evolution and spread of this disease over time and space, more and more research is focused on obtaining mathematical models that are able to predict the evolution of active cases based on different scenarios and taking into account the numerous inputs that influence the spread of this infection. This paper presents a web responsive application that allows the end user to analyze the evolution of the pandemic in Romania, graphically, and that incorporates, unlike other COVID-19 statistical applications, a prediction of active cases evolution. The prediction is based on a neural network mathematical model, described from the architectural point of view.

New Framework

<p>'Tangible lighting controls' is used as an umbrella term to describe lighting control systems that are easy to understand and pleasurable to use by end-users. The crucial question posed is, what is the nature of interface designs sought by end-users for maximising interaction with lighting control systems? The manner in which this question is posed implies a fundamental assumption that improved usability and end-user experience are the primary goals. The concept of end-user understanding of lighting control interfaces is proposed as a basis for improving the usability and end-user experience of lighting control interfaces. Usability engineering methods involving survey research, experimental mock-ups and prototyping have been used to enable end-users to design and evaluate lighting control interfaces. The essential difference is to include end-users' point of view about ease of understanding control functions and pleasure of performing control tasks along with a technical point of view about meeting required standards. Manufacturers' claims about the effectiveness of existing lighting control interfaces are challenged, and an entirely different way of thinking about interface design is revealed. Such a change of thinking may be seen as a new framework for improved designs of lighting control interfaces as well as evaluation of their usability and end-user experience.</p>

Abstract: Introduction: The teaching of neuroradiology in undergraduate medical school must be seen as an integration tool for the interdisciplinary study of radiology, anatomy and neurology. In practice, there is a limitation on the part of students in acquiring such knowledge, either due to “neurophobia”, or due to the lack of previous anatomical-radiological knowledge and also due to the lack of integrated didactic materials aimed at undergraduate school. However, there are few studies reporting the difficulties encountered by students in learning neuroradiology. Objective: To assess the perception of medical students about learning difficulties in neuroradiology. Method: Quantitative study, carried out with medical students enrolled in the second and seventh semesters of a university in Fortaleza. Data were obtained through a structured questionnaire with 12 yes or no answer questions. The questions addressed the possible difficulties encountered in acquiring neuroradiological knowledge, among them: the lack of targeted didactic material, the lack of integration with neurology, the need for basic radiological and anatomical knowledge, the large volume of content to study, and the limitations of active and traditional methodologies. Results: 181 questionnaires were analyzed. Most students report as difficulties: the need for basic knowledge of radiology (80.1%); neuroanatomy (77.5%); and to correlate radiology and neuroanatomy (70.9%). When comparing the 2nd semester and 7th semester groups, there was a greater tendency to point out the lack of practical knowledge of neurology by 2nd-semester students as a factor of greater difficulty in learning neuroradiology (82.6% versus 67.4 %, with p <0.0018). When asked about the usefulness of creating an e-book aimed at undergraduate students for learning neuroradiology, 85.6% of the students answered affirmatively; in the case of a mobile application, 92.3% agreed. As for the correlation between neuroradiology and medical practice, 98.3% answered that it is useful and necessary knowledge. Conclusion: In the students’ opinion, previous knowledge of neuroanatomy and clinical neurology is important for learning neuroradiology. The development of material such as an e-book or mobile application focused on integrating the teaching of these disciplines is considered a good alternative to facilitate the understanding of neuroradiology.

a modern education system must meet the needs of society. But from the point of view of considering the theoretical side of the issue, the education system that provides educational services is a service provider not only for the end user of the service. In various views of the theory of the question, educational services are considered as services for the state, society and the student. The article considers the main approaches to determining the quality of educational services and the regulatory and legal support of the educational process. The object of the research is the theoretical foundations of the quality of educational services. The subject of the study is the quality of educational services.

Commercial Transaction

In an Internet commercial transaction, the secure Web server and the buyer’s computer authenticate each other and encipher the data transmitted using transport layer security (TLS) or secure socket layer (SSL) protocols. When a purchase is made online using a credit card, does the customer’s bank need to know what was purchased? Not really. Does the seller need to know the customer’s credit card number? Actually, the answer is no. The responses to these questions were the main premises of the secure electronic transaction (SET). In the late 1990’s, SET was approved as the credit card standard, but it failed to be accepted because of its cost and the problems regarding distribution of end-user certificates. However, SET is explained in this chapter as an ideal protocol, from the point of view of certificates, digital signatures, and cryptography for securing credit card transactions over the Internet.

The Individual

In general, users who access Web sites do not necessarily have the same abilities in terms of cognitive, sensory and physical conditions. An accessible Web site is one whose content can be used by as many users as possible; and to improve accessibility, the use of evaluation tools has been incorporated among other resources. However, from the point of view of the end user, the evaluation obtained by most of these tools does not fit to the individual needs and abilities of the users. On the other hand, there is a greater understanding of the need to automate the support to reach higher levels of accessibility. Promoting this type of support on both the developer and the end-user sides is a complex procedure that can be done by incorporating intelligent features, such as the collaborative participation of intelligent agents. In this paper, we introduce a multi-agent system based on visually impaired user’s profiles to improve Web Accessibility assessment. The proposal is validated through a proof of concept, by contrasting results against 10 wide-known assessment tools. Our results show that evaluations are more focused, and therefore, unnecessary assessments are avoided improving efficiency.
