Gotsev, Lyubomir; Dimitrova, Milena; Jekov, Boyan; Kovatcheva, Eugenia; Shoikova, Elena (Bulgaria)
ABSTRACT:
The punctilious understanding of where and how Data Science creates a value-added in IoT network security lies in the applied experimental session evaluating the performance of particular machine learning models for attack detection. Results stand as a base demonstrating the benefits of the emerging technologies integration for predicting threats issues. Furthermore, implementing machine learning to intelligent security systems deepens the need for a multi-disciplinary approach and data e-infrastructure to manage the whole lifecycle (Software Engineering end-to-end, including ML and Data DevOps).
Comparative performance analysis of the algorithms that have proven helpful in mitigating security in IoT domains such as Support Vector Machines, Random Forrest, Naïve Bayes, Logistic Regression, Decision Tree is presenting. The case study is accomplished by conducting experiments with the public available IoT-23 dataset containing labeled information of malicious and benign IoT network traffic. The benign scenarios were obtained from original hardware and not simulated. That allowed to be analyzed real network behavior. As a result, models produce accurate outputs usable to predict and detect vulnerabilities in IoT-based systems. Besides, the lab could be multiplicate for creating business and industrial demonstrators to present the advantages of developing intrusion detection tools featuring machine learning algorithms.
A Hawaiian Fishpond as an Educational Interdisciplinary Nexus
Widiasih, Esther; Garrido, Xavier; Johnson, Tanner; Kupihea, Kehaulani (United States)
ABSTRACT:
Loko iʻa, or traditional Hawaiian fishponds, backed by thousands of years of wisdom and knowledge of the kupuna (ancestors), were ecological treasures that thrived because of their harmonious connection with the surrounding land and water. Rather than imposing on the land, kupuna seek to understand the relationship between tidal flows from the ocean, the nutrients from the watershed, and the fish in the pond. As a result of this understanding, kupuna strategically choose locations for loko ʻia that amplify the abundance of the surrounding area. The end product is an expanse of the sustainable food production system from mauka (mountain) to makai (ocean). Sadly, most ancient fishponds have been destroyed or overrun by development. Various efforts are underway to restore the few that survive by integrating traditional knowledge and current technology.
An example of this effort is done in a fishpond on Mokauea Island, off the south shore of Oʻahu. Once a small holding pen for young fish (kiʻo pua), the fishpond was enlarged in the early 1980s to the size of a football field. Recently, temperature, dissolved oxygen, water level, and flow rate sensors were deployed to understand basic physical characteristics of the pond. Mathematical models were adapted to analyze the observed data, and used to understand climate change effects.
While the modeling and the computational aspects of this work is interesting, the emphasis of the work is on developing interdisciplinary projects and classroom materials drawn from real world applications. As an ecologically integrated food system, a fishpond is an excellent nexus for interdisciplinary projects. For example, the mathematical model for dissolved oxygen level necessitates the understanding, among others, the wind regime of the area, sediment oxygen demand, and surface and water oxygen saturation levels. At the heart of this work is preparing future generations by making a connection between ancient knowledge with current technology, data analysis, mathematical modeling. In this vein, an equitable relationship with the indigenous knowledge keeper and the land stakeholders is the key to the success of the project.

An Assessment of Knowledge Areas for Advanced Diploma in Engineering Using Fuzzy Analytic Hierarchy Process (FAHP)
Ilunga, Masengo (South Africa)
ABSTRACT:
This study uses Fuzzy Analytic Hierarchy Process (FAHP) technique to assess consistency among knowledge areas of the advanced diploma in Engineering (AdvDipEng) programme/course. This course is taught in South African universities of technology and comprehensive universities. For the purpose of formulating and implementing FAHP, knowledge areas are the main criteria that an engineering programme should fulfil. Experts and decision-makers’ opinions have a level of subjectivity, imprecision, even some uncertainty, ambiguity, hence fuzziness. Fuzzy pairwise comparisons are established qualitatively among criteria using triangular fuzzy numbers (TFN1) from (1,1,1) to (9,9,9) whereas the computation of criteria weights is carried out quantitatively through FAHP. TFNs linked to a fuzzy distance of 1 from the crisp values are used in this study within the scale 1 to 9 and the corresponding FAHP is noted as FAHP1. Then the credit weight of each knowledge area is computed consistently through the same technique. Generally, the existing knowledge area credit weights of the AdvDipEng were validated through FAHP1, although small differences were observed in credit values.
Analytic Hierarchy Process (AHP) for Evaluating Knowledge Areas of Advanced Diploma in Engineering Taught in South African Universities
Ilunga, Masengo (South Africa)
ABSTRACT:
Analytic Hierarchy Process (AHP) technique is explored for measuring consistency among knowledge areas of the advanced diploma in Engineering (AdvDipEng) programme in South African universities of technology and comprehensive universities. The technique subsequently enables to carry out the credit weight of each knowledge area and compare it with its existing weights in the programme, as set by the Engineering Council of South Africa. In the AHP formulation, knowledge areas were approached as main criteria inherent to any engineering programme. Pairwise comparisons among knowledge areas were carried out consistently through AHP, which displays both qualitative and quantitative characteristics. The results revealed an acceptable level of consistency in the credit allocation among knowledge areas of AdvDiplEng. Overall, AHP validated the existing ranking order of knowledge area credits, however showed minor discrepancies in credit values from ECSA credit weights.
Assessing Knowledge Areas Consistency and Optimism Level for Advanced Diploma in Engineering Using Fuzzy Analytic Hierarchy Process (FAHP)
Ilunga, Masengo (South Africa)
ABSTRACT:
Consistency check and optimism level are conducted among knowledge areas of the advanced diploma in Engineering (AdvDipEng) qualification. The Fuzzy Analytic Hierarchy Process (FAHP) model is used for the purpose of the study. This course is part of engineering technology taught in South African universities. Knowledge areas are used as main criteria in the evaluation process, through FAHP. The establishment of pairwise comparisons between criteria uses mainly qualitative fuzzy triangular numbers (TFN) which are derived from the crisp numbers of the likert scale 1 to 9 and are named in this study as TFN2. For convenience, these triangular numbers are associated with FAHP2 or FAHP type 2. The TFN2 elements are considered for a fuzzy distance of 2 on the boundaries and odd values, and a distance of 1 on the intermediate values from crisp values. The subjectivity, uncertainty/vagueness characteristics of pairwise comparisons in FAHP2 are coupled with the degree of optimism from the decision-makers involved in the credit allocation for the different knowledge areas. The weights are determined quantitatively from the judgment matrix of fuzzy pairwise comparisons when consistency is satisfied. The weight calculation takes into consideration of some optimism level. The weight distribution among the knowledge areas from FAHP2 is compared with those from the existing weights.
Creation of a Computational Model from the Perspective of the Functional-Structural Theory of Talcott Parsons – Case Study: The Emergence of the Mexican Bolero
Fernández de Velazco, Fuensanta; Carpinteyro-Lara, Eduardo; Rodríguez-Luna, Saúl (Mexico)
ABSTRACT:
In this article, we present, as an example of a case study, the emergence of the Mexican bolero. In 1959 Parsons elaborated a systemic model of perception of the musical act, in which the creative act of the musician develops between the demands of his role as composer and performer and the conditions imposed by society. This relationship also involves the interpretation of the inherited musical culture and is related to the composing skills of the author, the instrumental technique of the performer, and musical intelligence. Thus, from a sociological point of view, the identity of the Mexican bolero is understood as a product of an era, in which both the composition and the musical performance are adapted to their cultural environment and are part of society and its structure.
Based on Parsons' proposal for a systemic analysis of the musical act, we create a conceptual model and develop it into a computational model, in which we intend to measure the different variables of the musical act system in different contexts and temporal spaces.
In the model are represented, through four modules, the four Systems: Personal, Behavioral, Social and Cultural of the Systemic Model of the Musical Act of Parsons. The interrelationships between the systems are also represented, which Parsons mentioned as internalization, learning, and socialization processes.
Discovering Patterns Across Disciplines: Cybernetics, Existentialism and Contemporary Art
Dixon, Steve (Singapore)
ABSTRACT:
Gregory Bateson observed that cybernetics is not essentially about “exchanging information across lines of discipline, but in discovering patterns common to many disciplines”. This paper adopts his line of thought to join the dots between cybernetics and the philosophy of Existentialism, and then interconnect both with contemporary art. It demonstrates that while terminologies may differ, many of the three fields’ primary concerns closely cohere. The world’s most ground-breaking artists are found to apply and fuse cybernetic paradigms and Existentialist themes, from Robert Rauschenberg and Marina Abramović to Damien Hirst, Stelarc and Anish Kapoor.
The research offers the first detailed comparison between cybernetics and Existentialism, and reveals surprising commonalities. Feedback loops, circular causality and negative entropy are not only central tenets of cybernetics, but also of Existentialism. Autonomy, autopoiesis and interactivity equally unite both fields, and each is visionary and forward looking in seeking radical change and transformations. Both explored artistic endeavours, with Existentialists Jean-Paul Sartre and Albert Camus equally renowned for their powerful novels and plays as their philosophical works, while cybernetic art became a major phenomenon in the 1960s following the landmark exhibition Cybernetic Serendipity: the Computer in the Arts (1968), and influenced artistic practices thereafter.
Education and Technology
Marzullo, Rossella (Italy)
ABSTRACT:
The aim of this paper is to explore what we know about the difficulties of comprehension of digital texts in comparison with traditional texts with a particular focus on new readers. The question we want to investigate is whether the reading of an electronic text is more (or less) difficult than that of a paper text. In the first part of the paper, the object of the study is presented; in the second part research studies in the field are examined through an analysis of the evidence-based literature; in the third and final part, we try to draw some conclusions from data.
Do we read more or read less in the time of digital media? Does reading on the screen change the way we understand meanings? And does the way we write change? These are some of the questions that parents and teachers ask themselves to understand what are the correct spaces and times to leave for devices at home, at school, in free time.
Educational Technologies for Hybrid Learning Contexts: A Grid of 12 Technological Communication Tools
Manciaracina, Andrea Giuseppe (Italy)
ABSTRACT:
The mission of university goes beyond contributing to society with the results of its research and innovation. Its scope is prompting and supporting young people to gain new knowledge while encouraging them to consider/include forms of social engagement. Then, it is crucial for teachers to engage students in the learning process. Students use technology to communicate; thus, they are more likely and comfortable to participate in a technology-driven environment. This purpose could be pursued through the correct choice of educational technologies within the learning environments. Communication technologies have the potential to engage learners while also providing motivation and support for both teaching and learning. The paper focuses on the definition of educational technologies and on the description of a grid of 12 technologies that were chosen based on the research activities undertaken in a doctoral research at the Politecnico di Milano. Subsequently, the technologies are classified through different mappings and methodologies to produce a description and showing advantages, disadvantages, and contexts of use. Finally, it analyses the technologies from the point of view of 2 learning contexts, on-site and online, to help create new hybrid learning processes.
Emergency Criminal Legislation in the Times of covid19: The Case of Albania
Leka, Adrian (Albania)
ABSTRACT:
As part of its response to Covid19, the Government of Albania enacted emergency legislation in various areas, including amendments to the criminal law to criminalize behavior not consistent with the anti-Covid19 measures and the rules of quarantine. This article discusses the amendments and concludes that they [the amendment] disrupt the balance between liberty and necessity and are far from compliant with the Constitution of Albania and the ECHR, both substantially and because of the procedure conducted for their enactment.
Emotion Detection by Speech and Voice Tone
Wu, Yung-Gi; Jin, Zi-En; Lin, Chia-Liang (Taiwan)
ABSTRACT:
Among all kinds of mental illnesses, emotional psychosis is very common, and the main manifested symptoms are the three highs: unrestrained thinking, increased behavior, high emotions, and even hurt people; or the three lows: low mood, slow thinking, hopeless, and even passive suicide. The former manifests as mania, while the latter manifests as depression. This research aims to develop a negative emotion detection system to help people to know if there is negative emotion in his mind. If detected, system will provide further counselling or medical agencies information to help him. Speech is the main medium of communication between people. It contains a lot of rich emotional information. You can read other's joy, anger, sorrow, and happy through the conversation. We analyze the speech content and tone change in dialog to detect if he or she has negative emotions. The negative emotions detected includes melancholy, anxiety, sadness, fear and anger. This paper uses the clinical experience from the psychologist consultation to form the criteria to detect the emotion states. Meanwhile, system can record the long-term information to observe the changes of the user's emotions. Once the system finds serious condition, system can provide information to seek medical assistance immediately.

The combination of individual analytical work of the students, acquisition of teem job skills, the study of MS Project tools, IT project management methods at different stages allows to achieve the planned learning outcomes and develop interdisciplinary competencies.
Free Will: A New Formulation
Sanchis, Eric (France)
ABSTRACT:
Free will is sometimes summarised in the philosophical literature as the subjective impression felt by an individual that he or she is the ultimate source or cause of his or her own choices. The two most common arguments for denying the existence of free will come from philosophy and neuroscience. The first argument is the Consequence Argument. The second asserts that our decisions are first made by the brain and only then become conscious to the subject, taking away the control of the decision. The purpose of these two arguments is to demonstrate that an individual cannot be the source or primary cause of his or her choices. It is shown in this work that the concepts of primary cause and primary source are not adequate to state a solid characterisation of free will. A new formulation of this property is proposed in which it is seen as a three-stage decision-making process implemented by an individual to escape his or her own real or supposed alienation. This decision-making process is represented in the form of a computer model called the PSU (Predictability - Suspension - Unpredictability) model. The compatibility of this new formulation of free will with the feeling it provides and the analysis of various situations are then discussed.
Gamification Integration and Student Motivation: Issues and Concerns
Pournaghshband, Hassan; O'Dowd, Sean (United States)
ABSTRACT:
Among major challenges that today’s educator faces is how to motivate and engage their students. Problems of different nature regarding students’ motivation have been extensively studied by researchers providing guidelines for best practice in motivating and engaging learners in an academic environment. In this paper, we examine gamification motivation issues and discuss how it can be effectively integrated into the classroom environment. We will show how different types of gamification can be applied in a classroom environment to better motivate and engage students in learning material. The main idea behind the gamification approach is that it will allow students to become highly engaged in the topic, leading to better retention and recall of the material through game-like methodology. The promise of gamification is within the common game elements which facilitate the capturing of the learner’s imagination as they find the learning experience to be pleasurable throughout their coursework. While we trust that gamification works for both, graduate and undergraduate courses, but the nature of this motivation approach makes it a good choice to be tailored for undergraduate students.

Information Security in Pandemic Times – A Discussion Paper
Scholl, Margit; Schuktomow, Regina; Gube, Stefanie (Germany)
ABSTRACT:
How important is Information Security in pandemic times? With digital processes playing an increasing role in all areas of life, the growing phenomenon of cybercrime includes a broad spectrum of attack possibilities. The attackers have no regard for the pan-demic—on the contrary, they have taken advantage of the situation and increased their attacks. Information security is a constant concern and cannot be trained using just one method on just one occasion. It must be assumed that the necessary security culture in a company, in an institution, and in an organization such as a hospital can only be achieved with the help of continuous discursive security processes and ongoing, practical awareness-raising measures employing an interactive mix of methods. Here, blame must be avoided and mindfulness promoted. Major challenges need to be overcome, especially in times of pandemic, which introduces considerable stress into all work situations. Information security and the pandemic situation must be understood in terms of their interaction in order to continuously improve the security culture.

Interdisciplinarity as a Key Competence on Industry 4.0 Labor Market
Poszytek, Paweł (Poland)
ABSTRACT:
This abstract discusses interdisciplinarity competence, understood as an effective use of knowledge, skills and practices from two, or more subject areas. Interdisciplinarity is presented here in the context of the main features of the industry 4.0 and related competences. The discussions on the concept of competences 4.0 in the context of 4th industrial revolution, or industry 4.0, have been being growing recently and extensive analyses and researches have been being carried out by experts within various scientific disciplines such as management, economy, psychology, education, human resource, informatics and systemics. Due to the relevance of industry 4.0 concept in relation to current socio-economic challenges worldwide, the growing interest on the part of researchers and the proliferation of the above-mentioned terms in literature has formed a complicated network of patterns and relations constituting a scientific landscape of the discussions in questions. Accordingly, the aim of this article is to explain the contextual terminology of these discussions, namely: industry 4.0 and competences 4.0 and discuss the nature of interdisciplinarity as one of the key factors defining future skills in the context of the new labor market needs.
Interdisciplinarity in the Construction of a Videogame as an Intervention Tool in School Conflict
Esparza, Norma; Restrepo, Dayana; Guerrero, María C.; Hoyos, Olga (Colombia)
ABSTRACT:
The objective of this work was the creation of a video game as a tool for prevention and intervention against school conflicts for children fromages 9 to 12.A team of professionals in psychology, education, computer science, art, and music achieved the construction of an innovative product, which, through the use of multimedia, presents an adventure story that confronts players with ethical dilemmas. As the user advances in the game, their actions delimit a gamer profile, associated with specific characteristics of each stage of human moral/social and cognitive development.
Historically, games have a fundamental role in the development of children, involved in the structuring of thought and language, and in the transmission of social norms and values in all cultures [1]. In post-industrial societies, computer technologies have granted the creation of games on virtual platforms, which have resulted in a highly motivating context for children and adolescents to consolidate academic knowledge, skills and attitudes [2].
Despite extended studies on the uses and benefits of video games in learning, the process of building an educational video game is not sufficiently represented in the scientific literature. The contribution of computer science in technological programming, art in the design of interfaces, music for the setting of the narrative, as well as the social sciences to propose learning objectives and challenges according to the psychosocial development of the younger players are all fundamental aspects of a successful video game design. In the present work, computer science covered the programming determinant for the compatibility of the game with different devices (cellphone, computer, tablet), as well as the technical appreciations to be taken into account within the graphic style, in coherence with the type of platform (2D), and the Unity 3D engine editor. The artistic design (color palette, language of shapes) imprinted the visual style of the game, the identity of the characters, the reward props, typography, and other various aspects of illustrations. The composition of eight musical pieces allowed to connect the visual environment of the game with the moods and the psychological state of mind of the characters, and of those situations in which they were involved, expressing tension and danger, or joy and triumph. Psychology and education were central in the proposal of situations that favored empathetic reasoning, perspective-taking, prosocial behavior, development of deductive and inferential logical reasoning, problem-solving strategies, and self-regulation of behavior [3].
The result of this collaborative work was a platform video game, rated E10+, for educational, preventive, and diagnostic purposes. The story takes place in a fairy world where the characters (witch, dragon, hunter, gnomes, and vampires) are immersed in a problem that denotes difficulty in their interpersonal relations. The player assumes the role of an Elf who, as he/she explores the forest, becomes involved in the conflicts of the other inhabitants. Throughout the decisions made by the player, the system characterizes the cognitive-ethical profile of the player. This characterization is made based on player decisions regarding the way they use weapons, how they relate to the characters and game rules, and whether they reach the goals of the game.
The developed game offers a tool for school counselors and teachers for tailoring specific intervention plans for students and how they think of and approach conflicts with other. Such work would have been impossible to achieve from a single area of knowledge; the collaborative production scheme allowed for the creation of a concrete product that contributes to the social development of a community.
Linguistic Philosophy of Cyberspace
Makhachashvili, Rusudan; Semenist, Ivan (Ukraine)
ABSTRACT:
In the early 21st century the human mind has progressed in the methods of reality perception. The inquiry objective is the investigation of the innovative philosophic aspects cyberspace through the lenses of the language development processes in the sphere of new computer technologies and digital communication. The study design is the disclosure of cyberspace as an ontology model and as a logosphere model. The linguistic philosophy approach to the study of cyberspace allows to efficiently investigate the empirical manifestation of cyberspace ontology (space and time dimensions), the generic categories and dimensions of cyber-epistemology, to denote existential anthropocentric character of cyberspace. Philosophical foundations of the study of cyberspace as an integrated macro- and micro-entity are determined by the substantive features of innovative logosphere as a macrostructure and by the phenomenological characteristics and properties of substrate of linguistic units of innovative cyberspace logosphere.
Reduction of Workplace Accident Rates Using Mathematical Statistical Models
Pons Murguía, Ramón A.; Villa González Del Pino, Eulalia M. (Ecuador)
ABSTRACT:
The objective of this research was to select the best regression model that would allow identifying the variables of the Occupational Health and Safety Systems, which have a greater impact on the occurrence of accidents, to project programs of improvements in order to reduce accident occurrence rates.
The research was conducted with a sample of 24 small and medium-sized Ecuadorian companies. The causal factors to be investigated were Occupational Health Management, Occupational Risk Prevention Management, Management of Natural Hazards / Anthropic Risks and Document Management. The mathematical models subjected to analysis to determine the relationship between the causal factors and the number of accidents were the Poisson, Negative Binomial and Logistics Regression models. STATGRAPHICS Statistical Software was used to determine the model with the best goodness of fit. Statistical inference was made by comparing Poisson, negative binomial and logistic regression models, the latter being the one that presented the best fit. The application of the designed intervention plans made it possible the observation of improvements in the performance of these systems, which was evidenced by a significant reduction in accident rates.

The study demonstrated an increased ability for students to personalize their educational experience, which leads to more a clearly identifiable program and to an improved value-proposition and how the process resulted in the creation of a one-credit orientation seminar that contributes to increased student retention and enhances diversity to the major.
Resilience Profiles Associated with Social Support and Engagement for Overcoming Academic Obstacles in Undergraduate Education
Restrepo Cervantes, Dayana; Marenco-Escuderos, Ailed Daniela; Rambal Rivaldo, Laura Isabel (Colombia)
ABSTRACT:
Entering college is considered a milestone in human development given that it involves life changes related to the acquisition of considerable independence at an early age, incursions into new roles in the community, demanding study conditions, and the reorganization of personal support networks. While most individuals take advantage of the university years to develop work related and social skills, a significant number of students encounter greater challenges adapting to the new environment, and for them the university conditions result in a source of clinical discomfort highly detrimental to their mental health, reflected in poor academic performance, isolation, and student desertion [1].
The main objective of this work was to explore the configuration of those elements that allow students to better adapt to university environments and to persist even in the presence of difficulties. We focused our analysis on personal and social factors as interrelated resources that enable adaptation. First, we explored the resilience of university students as the ability to respond to obstacles with a positive view of the environment, of others and of one’s own abilities to cope with stressors. Secondly, we reviewed the level of engagement that drives young people to concentrate their energies on academic activities and thirdly, as the university context is a context of social interaction, it was necessary to investigate the role of peers, and friends as the closesupport system that facilitates the overcoming of personal and academic difficulties.
The sample consisted of 371 first-year undergraduate students (58% female), from low socioeconomic status, enrolled in public universities in the Caribbean region of Colombia. The methodological approach was based on a cluster analysis, in which, using the hierarchical agglomerative method, groups were extracted according to their similar characteristics of resilience in 12 dimensions evaluated by the SV-RES scale [2]. The grouping of subjects into clusters allowed us to observe how each group manifested a particular style of resilience, and subsequent analyses of variance reported how each style was associated with engagement, and with a particular constitution of personal support networks, assessed respectively with the UWES-S scale [3] and from a square matrix of reticular data on the social networks of each participant [4].
The results showed four profiles of students, characterized by: a) low resilience, high engagement, and strong support networks; b) resilience with low engagement, and dispersed support networks; c) resilience with high autonomy, intermediate levels of engagement, and weak support networks; and d) resilience, high engagement, and strong social support networks. The first larger group was constituted mainly by women while the last three groups had a higher proportion of men with resilient styles but different characteristics in engagement and social support. Our results evidenced important gender differences in the distribution of resilient styles. A greater proportion of women presented low levels of resilience; however, a high engagement and strong peer support networks were the conditions most related to overcoming problems associated to the academic life. To a lesser extent, strongly defined resilience profiles were common; these were observed mainly among men, who expressed greater confidence than women in their internal resources to face adversities. It is concluded that the results might point to cultural aspects from the Caribbean region, where social networks are of great importance for daily functioning, and traditional gender identities are maintained. Such identities entail men perceiving themselves as strong, and women perceiving themselves as less resilient and therefore resorting to social support.

The Block Algorithm Speed-up Computation of Aircrafts Mathematical Model and Simulation on CUDA Architecture
Kvasnica, Peter (Slovakia)
ABSTRACT:
The general-purpose graphics processing units as inexpensive arithmetic-processing units bring a relevant amount of computing power to desktop personal computers. The paper discusses exploitation of graphics processing unit features, computation time of a parallel method of implementation and improved simulation of a continuous mathematical model of aircraft motion in a flying simulator. The mathematical model design is adopted to the architecture of a graphic accelerator. The use and application of a modelling method and design on parallel graphics processing unit architecture determine a structure of a mathematical model used in a flying simulator. The efficiency is demonstrated by the results achieved in the simulation on two-parameter control of a mathematical model of aircraft motion. Results of a mathematical model of aircraft motion designed in this way show very high-speed computing and confirm efficiency of such a structure of a mathematical model for a designed simulator system.
The Effect of Financial Rent on Top 1% Income Ratio in Advanced Economies: An Evidence from Panel VAR Analysis
Siddique, Md Abu Bakkar (Japan)
ABSTRACT:
This study investigates the association between the financial rent and the top income in OECD economies. It explains the response of the top 1% income to financial rent using an impulse response function and describes its variation by decomposition analysis. Employing a panel vector autoregression model, we find that the top 1% income increases in response to rent shock. It implies that rent, measured as an excess profit and lower competition, has a significantly positive effect on the top 1% income concentration. Evidence shows that an excess profit is positively associated with monopolistic competition and asset concentration in the banking industry. Competition reduces the top income concentration. Our results suggest that an accumulation of income by a small group is detrimental to overall growth.
Towards a Framework for Assessing Cybersecurity Risks in Internet of Things (IOT) Devices
Qiao, Zhilei; Julio C., Rivera (United States)
ABSTRACT:
The term Internet of Things (IoT) refers to a broad class of devices used by business entities as well as consumers to provide or consume a broad array of services. All these devices share their need to connect to the internet to deliver their native functionality. This connection requirement exposes the devices to the cybersecurity threats found on the internet. Existing literature on IoT cybersecurity solution models has shown that different technologies, such as communication technologies, mobile-app based authorization framework, graph-theoretic approach or block-chain technologies, have been majorly proposed to solve IoT security issues. However, these studies only focus on some specific IoT security issues like data theft or security issues on some specific layer across the whole IoT architecture. Therefore, there is a lack of systematic framework to solve IoT cybersecurity issues. This paper presents a framework for assessing such risks. In the qualitative analysis results, the device threats seem more severe than data confidentiality and privacy issues. This surprising finding highlight the significances of security taxonomy because both two issues are based on different technical requirements. Our study has important managerial and practical implications for users, managers and policy makers.
Towards Modeling Semi-Automatic Ontology Based on Natural Language Processing

ABSTRACT:
Knowledge Engineering can support intelligent systems queries in specific domains. For example, customer queries in the banking sector can be supported by ontologies representing particular domain knowledge. However, manual construction of such ontologies may be a time-consuming process. This paper presents a semi-automatic ontology development approach based on natural language descriptions in Brazilian Portuguese. The method integrates Natural Language Processing tools to obtain RDF triples from texts and uses these triples to build ontologies with specialist support. The use cases for investments, banking services (e.g., account opening), and the comparison with manual process show the proposed method's capability to reduce manual labor in the ontology development process. Our approach further extends literature RDF triples identification with Brazilian Portuguese syntactic analysis to identify more than one triple in each phrase.
