Published: January 2023

The background of this research is the weakness of the marine product supply chain which reduces the interest of the Indonesian people to consume abundant fish. The purpose of this study was to examine the effect of UTAUT and IRT factors on digital fishery platform acceptance. The study was conducted in the provinces of Banten and West Java using a convenience sampling technique. The data collected were 240 samples, consists of 151 samples from Banten province, and 89 samples from West Java province. The results of the study prove that three UTAUT factors, namely performance expectancy, effort expectancy, and social influence significantly affect the intention to use digital platforms. Three IRT factors have a significant effect on resistance to using digital platforms. However, this study also shows low resistance and high acceptance on the digital fishery platform, so that the effect of resistance on the intention to use digital fishery platforms is proven to be negative and significant. The novelty of this research is the combination of UTAUT and IRT theory on digital platform acceptance. The practical benefits of this research can be used as a basis for decision-making to build a digital fishery platform that will benefit marine fish consumers and fishermen.

Published: January 2023

Domain analysis is a primary approach to the representation of shared ontological bases in knowledge organization. The growth of domain analysis as a paradigm is demonstrated over a period of two decades. The Domain Analysis Clinic, or DAC is a core methodology generated for focused concept discovery combining meta-analytical theoretical research with the formation of domain-specific knowledge organization systems. The emergence of the DAC as a tool for meta-analysis and discourse analysis has demonstrated the efficacy of focused concept formation for taxonomic representation as well as for theoretical discovery in KO. The evidence presented here strongly directly suggests the continued honing and maturity of domain analysis as a paradigm in KO.

El objetivo de este trabajo fue analizar el uso de los recursos edu2.0 y las actividades interactivas apoyadas en la plataforma edu2.0 en la Institución Educativa Distrital Bellavista de la ciudad de Santa Marta, Colombia, para lo cual se tomaron como referentes teóricos los aportes de Aparici y García-Marín (2018), Martínez et al. (2019), Romero et al. (2019) y la CEPAL (2021) y de diversos trabajos académicos desarrollados en el área. Metodológicamente la investigación se caracterizó como descriptiva, no experimental, transeccional y de campo. Como población se incluyeron los 141 estudiantes cursantes de los grados Sexto al Noveno (censo) y como instrumento se usó un cuestionario de ítems escalares con cinco opciones de respuestas. La validación se realizó por medio del juicio de cuatro expertos en el área, mientras que la confiabilidad para asegurar la consistencia de las respuestas fue de α꞊0.72, resultado que se consideró altamente confiable. Los resultados evidencian que los estudiantes seleccionados hacen poco uso de los recursos edu2.0, lo cual permite deducir que no se aprovechan los beneficios que esta plataforma ofrece al proceso de enseñanza-aprendizaje; pero si muestran una utilización alta en las actividades interactivas. Se recomienda a la institución escolar brindar formación al cuerpo docente para reforzar sus competencias en el área e incentivas al estudiantado a emplear las herramientas disponibles, con el fin de estimular su creatividad y trabajo en equipo.

In recent decades, there has been a great interest in the use of ultra-wideband (UWB) radar methods for detecting living biological objects hidden behind various barriers. The wide frequency band of the UWB radiation makes it possible to provide a high penetrating power along with a spatial resolution sufficient to detect oscillations characteristic of the respiration of a living organism. This article considers a model of an ultra-wideband radar for detecting a living biological object located behind an optically-nontransparent obstacle. The considered radar model consists of two channels, each of which has two independent antennas with orthogonal polarizations, that supports implement processing orthogonal polarization echo signals. A method is proposed to increase the information content by using the amplitude, phase and polarization characteristics of the reflected signals. This is done in order to isolate the signals reflected from biological objects against the background of interfering reflections. The use of the proposed method leads to reduce amount of processed data and a decrease the probability of false detection.

Blockchain is a revolutionary new technology that facilitates peer-to-peer transfer of value without the need for a centralised intermediary. It uses cryptographic hashing functions, consensus protocols and decentralised data storage to ensure security, decentralised trust, immutability and transparency of business transactions. Blockchain technology paired with smart contracts is a reliable method of automating business rules in an efficient and trustworthy mechanism. A smart contract is a self-executing piece of code that runs on a blockchain platform. Predefined rules between participating organisations are translated into smart contract functions to establish trust. Blockchain is undergoing rapid development and has revolutionary potential for application in Intelligent Transport Systems applications. Blockchain can be used to create a secure, reliable and decentralised autonomous system, creating the best use of legacy infrastructure and resources. One of the most important issues is security, caused by the evolution of ITS towards centralisation. Fast-growing technologies, including the Internet of Things (IoT) and cloud computing, allow most data processing, analysis and decision-making to be done by centralised systems. The distinguishing factor of Ethereum is that it is programmed according to user requirements, rather than providing users with a set of predefined transactions, such as Bitcoin transactions. As a result, it could theoretically be used to automatically and securely execute any transaction involving trust, security or persistence. Although Ethereum is a relatively new implementation of blockchain, it has sparked reaction because of its potential to change the way many businesses operate.

The article deals with the actual task of identifying abnormal situations arising in information and telecommunication systems (ITCS) using artificial intelligence methods. Analysis of the processes of functioning of ITCS devices and nodes in real conditions shows that over time the properties of the analyzed characteristics can be transformed. Various factors cause the ranges of the analyzed values of the target variables to shift. The appearance of external and internal events at various points in time changes the states of both individual telecommunication devices and the system as a whole. It is necessary to analyze a large number of heterogeneous qualitative and quantitative characteristics of traffic and processes of functioning of telecommunication devices. The proposed method of monitoring the state of ITCS is based on taking into account the factors influencing the change in the properties of target variables, which, in turn, allows segmentation of the data sample. The novelty of the proposed solution lies in the fact that a classification algorithm with the best quality indicators is used for individual segments of the processed data. Taking into account the current and expected situations, it is possible to form samples based on the identified impacts. On the basis of the NSL-KDD dataset, segmentation of the data set is carried out, taking into account the influence of factors on the ranges of values. The processing of factors using the search function of the time series layout, which was used to segment the data set, is shown. As a result of data segmentation, a finite number of non-overlapping measurable subsets of data were obtained, each of which was fed to the classification algorithm. The evaluation of the quality of the classification algorithms was carried out. Based on the results obtained, it is possible to build various classification models of the ITCS information security (IS) status. The proposed approach makes it possible to improve the quality indicators of classification algorithms in dynamically changing conditions.

The problem of finding routes for unmanned aerial vehicles on various graphs of reference points on the ground using a genetic algorithm is considered. A comparison of methods for constructing graph functions based on the algebraic number-theoretic approach, as well as using transcendental functions, is carried out. Consideration of examples of objective functions constructed by algebraic methods taking into account the multiplicity of the numbers of vertices in a closed route shows that this approach leads to false routes for graphs of large dimension. This drawback can be eliminated by taking into account the individual information about each edge of the graph. This is ensured by encoding the edges of the graph by terms or by some numerical value in the form of its unambiguous expansion. The construction of the objective function is based in this case on the number-theoretic properties of the s-ary expansion or on the decomposition of an integer into prime factors. Number-theoretic objective functions uniquely take into account the individuality of each edge. Such coding of edges defines a theorem for constructing objective functions on graphs, based on the unambiguous expansion of a numerical value in a sum or product. Further studies show that not only numeric values can be used as numeric codes, but also functions that more fully reflect information about the features of routing functions on graphs and have the properties of an unambiguous expansion. The combination of the properties of the device and function leads to its transcendence and the possibility of using it in the construction of target functions. The constructed transcendental objective functions are tested on examples of various graphs. The relationship of the applied problem of routing unmanned aerial vehicles on the ground with mathematical optimization on graphs of means of number theory and a genetic algorithm is shown. Calculations of routes for transcendental objective functions can be applied in automated control systems.

Introduction: to date, the issues of substantiation, assessment and choice of options for the creation (development) of automated control systems for special purposes are not formalized enough and do not allow the selection of solutions to comprehensively take into account the totality of a number of significant parameters: prescriptive decisions; classification signs of command centers; functional processes of the highest priority; specified maximum permissible probabilistic-temporal and temporal characteristics of the performance of functional processes; information security requirements; design and reliability requirements; technological capabilities of executing enterprises; acceptable time and cost parameters of the system creation process; risks of untimely implementation of solutions for the development, manufacture of automation equipment and equipping command centers with them. Purpose: development of methodological and software tools for choosing solutions for the creation (development) of special-purpose automated control systems that maximize the efficiency of performing functional processes in the system, taking into account the specified requirements and restrictions. Methods: methodological tools are proposed, including the formalization of the structure of automated control systems for special purposes, the formulation of the problem of choosing solutions for their creation (development), as well as an algorithm for solving the problem, based on the use of "greedy" methods of discrete optimization.

Introduction: the existing development of methods for ensuring information security in the field of information technology allows you to control the confidentiality of personal data at variable levels. Hardware solutions can be portable cryptographic keys, as well as narrowly targeted biometric identification devices. Software solutions are methods of static verification using sequences and side-tools for deploying data virtualization systems. The main problem that stands out among the methods described above is the need for additional hardware that acts as tokens, infrared cameras, and biometric identification sensors. An alternative problem is the lack of security of software solutions, since the presence of zero-day vulnerabilities can reduce security, which leads to the possibility of interception of confidential data by third parties. Purpose of the research is expressed in the analysis and development of software methods and algorithms for ensuring data security based on containerization methods. The developed software solution allows you to perform application tasks in a secure container, while the implemented authentication methods support the ability to identify an individual both using sequences and using the Windows Hello application programming interface. Methods used: security methods and algorithms aimed at implementing a unique cryptographic algorithm. The results of the studied methods and algorithms for scanning a bounded shell allow us to variatively select the optimal outcomes of internal process instances along with the implementation of cryptographic methods. Application software is based on the joint use of virtualization tools and methods of interaction through neural network technologies. The isolation of this solution from alternative methods lies in the possibility of using the container without significant hardware resources and lack of primary knowledge in configuring the software module. Practical significance lies in the possibility of using methods and algorithms in the construction of secure jobs in small and medium-sized businesses.

Restoration of the serviceable state of complex technical systems is associated with technical diagnostics, the purpose of which is to determine the locations and causes of the malfunction. Improving the efficiency of diagnostics can be achieved through the use of automated information support tools that provide maintenance personnel with the required diagnostic information based on the generated request. The use of language query tools in systems of this type allows service personnel to formulate query conditions more precisely and specifically, but such tools require the development of additional models for interpreting conditions presented in natural language constructs. The purpose of the work is to develop a formal model that reflects the structure and rules for the formation of language queries in which diagnostic features are determined. The goal is achieved by consistently describing the procedures that determine the lexical, syntactic and semantic rules for analyzing language requests of service personnel to an automated information support system. The given sequence of language analysis procedures provides for the selection in the language requests of the service personnel of a formal set of diagnostic features that are used to form a formal request to an information source of information about faults in electronic equipment. It is shown that the machine parsing of such queries, which are called descriptive diagnostic queries in this work, is expedient to be performed by identifying the correspondence of language constructions to a set of formal rules determined by the grammar of a natural-like language. The studies carried out confirm the possibility and create conditions for the inclusion of inquiry-response means into automated information support systems for technical diagnostics and repair, which ensure the formation of probable places and causes of faults in radio electronic equipment at the request of the service personnel, made in the designs of the natural (Russian) language. The introduction of such a mechanism into automated systems will reduce the number of non-productive losses that are not directly related to diagnostics, which will have a positive effect on the time indicators of the restoration of complex technical complexes.

Introduction: methods for analyzing big data of reliability of multichannel systems with a loaded reserve with nonrecoverable elements are considered. Big data contains information on the operating time to failure of elements, obtained by monitoring the operation of similar systems. The main problem that arises when analyzing big data is related to its variety and veracity. Reliability data of system elements correspond to different operating conditions and different laws of failure distribution. The exponential approximation of failure distributions greatly simplifies reliability analysis. However, it can lead to significant errors and requires a separate justification. Purpose: development of approaches to the analysis of heterogeneous big data of reliability of system elements characterized by different distributions of failures. Derivation of estimates of the accuracy of approximation of the distribution of failures by exponential laws and criteria for the possibility of such an approximation. Results: methods for calculating the mean time to failure of systems with a monotonic structure are described. An estimate of the error of exponential approximation of the distributions of failures of elements of a multichannel system is obtained. The relationship between the error of exponential approximation and the coefficient of variation of non-exponential distribution of failures is shown. The case of two channel systems is investigated in detail. For uniform, lognormal, gamma and Weibull distributions, the dependences of the average operating time to rejection of the coefficient of variation are plotted. Areas of variation of the coefficient of variation of these distributions are constructed, for which exponential approximations are justified. An algorithm for constructing the mean time to failure in the analysis of large reliability data of a non-recoverable two-channel system is presented. Practical relevance: analysis of reliability data obtained from monitoring the operation of similar systems eliminates costly reliability tests. The relationship between the sample coefficient of variation and the error of exponential approximation of failure distributions in the analysis of big data of system reliability is shown. This connection forms the basis of the criterion for the possibility of such an approximation.

Introduction: Nowadays virtualization is used everywhere, and it is especially necessary for creating the network and server infrastructure of the enterprise. Without mathematical forecasting, it is impossible to accurately predict the behavior of the infrastructure over a time period. Consequently, the task was set – to create the most accurate forecast for the longest possible period. Methods: To create the forecast, an Autoregressive Integrated Moving Average model based on time series was chosen. This model has several different modifications, such as a stately model, an extended model, a seasonal model. The description of the Autoregressive Integrated Moving Average mathematical models, as well as the extended model of the Autoregressive Integrated Moving Average and the seasonal model of the Autoregressive Integrated Moving Average, are considered. Based on the mathematical description, the forecasting methods were studied and compared. Then the methods of mathematical forecasting were implemented in software, graphs were built, a comparison was made, and the best of them was identified to predict the behavior of the network infrastructure. The tests showed that the Autoregressive Integrated Moving Average model predicts the behavior of the network infrastructure for a week, the extended Autoregressive Integrated Moving Average model predicts the behavior of the network infrastructure for a month, and the seasonal Autoregressive Integrated Moving Average model predicts the behavior of the network infrastructure for a year. Practical significance: The results obtained based on the results of the Box-Jenkins mathematical forecasting modeling have wide practical application for monitoring a load of virtual infrastructure elements in order to prevent system failures and track anomalies, which increases the efficiency of resource use and infrastructure security.
USING MPLS TECHNOLOGY TO SOLVE BGP “BLACKHOLE” PROBLEM
Authors:   Tartous University, Khalil Knaj Nouma
Published: January 2023

Traditional IP networks use a hop-by-pop principle for transmitting traffic. This leads to aggregation of heterogeneous traffic on links in different parts of the network, which causes considerable possible growth of congestion and leaves the network with both unbalanced use of resources and link failure in congested parts. To support a growing number of users and multiple classes of applications with different performance requirements and characteristics, service providers have been forced to adapt to new technologies. Researchers have found that conventional IP packet forwarding is not suitable for applications such as VOIP and video conferencing, which are currently in huge demand. In addition to offer a general provision of MPLS technology, architecture, operation method and features, we will consider the Border Gateway Protocol (BGP) “Black hole” issue that results in the inability of the network to transfer traffic between some end points, and how MPLS help us avoid this problem and even optimize network operation and resources utilization.

While 5G rollouts are by no means complete, they are well under way. For many in the industry, efforts to utilize 5G to go beyond simply providing “fast connectivity” are already in focus. Our articles explore how the industry is already looking forward to what comes next, asking how to: make gains in sustainability; utilize technologies like IoT and edge to maximize efficiencies and push exciting use cases; use 5G as a springboard for innovation; truly capture the opportunities for all consumers and enterprises in all regions; and, with all this growing potential, how to keep 5G safe and secure. 5G technologies play a key role in modernization, providing multiples of capacity while becoming more energy efficient. Innovative network technologies enable service providers to introduce new services that in turn support societies and enterprises to reduce their carbon emission foot-print. In this edition, we share some examples of how 4G and 5G technologies make it possible to unleash the power of IoT connectivity to enhance both enterprises’ business performance and sustainability. The transition to cellular LPWA and 4G/5G technologies makes it possible to unleash the power of IoT connectivity. We explore the positive impact of these technologies in areas such as business efficiency and sustainability. Deploying edge computing is key to enabling latency-critical and bandwidth-hungry 5G use cases, and can cost less than onpremise IT resource for an enterprise. This capability represents huge untapped growth potential for service providers. As 5G grows in prominence due to advancing digitalization, networks become a more enticing target for threat actors. We explore the motivators, opportunities and capabilities of threat actors, and how to protect 5G networks.

For many companies, setting up a VPN for secure, encrypted communication is a cost-effective alternative to purchasing, operating, and managing a separate physical network. Many institutions, corporations, government agencies and nonprofit organizations want to have their own private IP network for secure and reliable connectivity between offices across multiple geographies. A virtual private network (VPN) is a secure, encrypted connection over a public public network. Creating a separate network requires the purchase of equipment, its installation and maintenance. A VPN-based solution using the public Internet is becoming a cost-effective solution for many corporations. As a research task, the authors define an assessment of the impact of the tunneling technology used to solve problems arising from the lack of network support from existing data transfer protocols. The possibility of using the IPSec protocol and MPLS technology to implement tunneling is considered and compared. The results of the comparison and evaluation of the impact of the choice of protocol on the required bandwidth are presented.

Background. Understanding the hospital impact of influenza requires enriching epidemiological surveillance registries with other sources of information. The aim of this study was to determine the validity of the Hospital Care Activity Record – Minimum Basic Data Set (RAE-CMBD) in the analysis of the outcomes of patients hospitalised with this infection. Methods. Observational and retrospective study of adults admitted with influenza in a tertiary hospital during the 2017/2018 and 2018/2019 seasons. We calculated the concordance of the RAE-CMBD with the influenza epidemiological surveillance registry (gold standard), as well as the main parameters of internal and external validity. Logistic regression models were used for risk adjustment of in-hospital mortality and length of stay. Results. A total of 907 (97.74%) unique matches were achieved, with high inter-observer agreement (ƙ=0.828). The RAE-CMBD showed a 79.87% sensitivity, 99.72% specificity, 86.71% positive predictive value and 99.54% negative predictive value. The risk-adjusted mortality ratio of patients with influenza was lower than that of patients without influenza: 0.667 (0.53-0.82) vs. 1.008 (0.98-1.04) and the risk-adjusted length of stay ratio was higher: 1.15 (1.12-1.18) vs. 1.00 (0.996-1.001). Conclusion. The RAE-CMBD is a valid source of information for the study of the impact of influenza on hospital care. The lower risk-adjusted mortality of patients admitted with influenza compared to other inpatients seems to point to the effectiveness of the main clinical and organisational measures adopted

The present outbreak of Human Monkeypox (HMPX) that has begun in May 2022 and has spread across all continents in less than two months has qualitative and quantitative characteristics that make it different from the pattern of human disease previously caused by this virus. It has spread with enormous ease, affects almost exclusively adults, behaves as a sexually transmitted disease and focuses on very specific groups and transmission conditions. The high incidence in the city of Madrid in males that have sex with males (MSM) has allowed us to observe and report the experience with the first 30 cases diagnosed in our institution. Patients presented with febrile symptoms, genital and paragenital skin lesions reminiscent of smallpox, but less extensive and severe. The disease may also cause proctitis, pharyngitis and perioral lesions. The PCR test for diagnostic confirmation has been shown to be very sensitive and effective, not only in skin lesions but also in blood and other fluids such as pharyngeal, rectal exudates and blood. A very high proportion of patients with HMPX also have other sexually transmitted diseases that must be actively detected in this context. The spontaneous evolution of our patients has been good and hospitalization has been practically unnecessary. Transmission to non-sexual cohabitants and health personnel has been nonexistent and the lesions have disappeared in less than 30 days without leaving sequelae and no need for specific antiviral treatment.

El trabajo tiene el objetivo de analizar el uso de las Tecnologías de la Información y Comunicación (TIC) en las micro, pequeña y mediana empresa de servicios turísticos en Puerto Vallarta, para conocer las herramientas y plataformas tecnológicas que utilizan. El diseño metodológico se fundamentó en una investigación de tipo no experimental, descriptiva y transversal con enfoque cuantitativo, realizada sobre la aplicación de un cuestionario administrado a la población objeto de estudio. Se levantaron 50 encuestas que fueron enviadas por correo electrónico y vía telefónica. Entre los principales resultados se encontró que cuentan con acceso a internet, computadoras y página web propia, que utilizan principalmente para la promoción de sus productos o servicios, la atención a clientes y la contabilidad de sus operaciones. Asimismo, cuentan con un alto nivel de adquisición de las tecnologías de información en el área administrativa y consideran importante invertir en ellas para la automatización de los procesos y la satisfacción del cliente, aunque se vea reflejado en el mediano y largo plazo.
The Relational Constitution of Remedy: Co-Operation as the Implicit Second Principle of Remedies for Breach of Contract
Authors: Campbell David
Published: January 2023

Whereas the principle of protecting the claimant's expectation is, of course, so well known as to be trite law (until recent developments in the law of restitution in particular have called it into question in England and Wales), the second principle is, to say the least, obscure. Though it is my basic claim that the specific legal rules constituting the second principle do already exist, the principle is not merely not recognised but is denied by those who understand breach as amoral or immoral, and this failure of recognition may be taken to extremes of antagonism in the attitudes and conduct of the parties (and their advisers) to strenuously contested commercial litigation. It is not the least ambitious of my aims that I intend my argument to have the clear implication for those parties that they should eschew this antagonism, which fails to represent, not merely their counterparts', but their own best interest, were they adequately self-conscious of it.
Enforcing the Contract at All (Social Costs: The Boundary Between Private Contract Law and the Public Interest
Authors: Zalesne Deborah
Published: January 2023

Using the examples posed by the panelists, this Article explores the limitations on the ability of contract law to deal with the protection of third parties and the public. This limitation is manifested in two distinct ways: (1) Commercial contracts are typically enforced without regard to the negative impact they may have on the public; and (2) although some courts appear willing to stretch the bounds of the law to ensure contracts are enforced in commercial contexts, there has been substantially less motivation to enforce contracts for the public good. Accordingly, Part III will discuss the innovative and flexible nature of the common law of contracts as it applies to protecting commercial interests and players and its concomitant insensitivity toward the public interest. Part IV will address the inadequacy of contract law as a means of protecting public and non-economic interests.
