A Method for Simulating an Information System with Life Cycle Simulation

Given the rapid growth of digital technologies, the use of information systems (ISs) is increasingly important for businesses positioned within the circular economy (CE). When designing an IS for such businesses, it is essential to simulate how the IS affects the life cycle (LC). However, existing research has not yet addressed this issue. For example, life cycle simulation (LCS) mods an LC and evaluates the economic profit and environmental impact of a product across its entire LC but does not explicitly model the IS and the effect from IS on LC is not simulated clearly. In this study, we propose a modeling method (E-DFD) and a simulation system (ISS) for modeling and simulating the IS. In the E-DFD and the ISS, we model and simulate an IS as a set of functions. Additionally, we propose a method that facilitates cooperation between IS simulations and LC simulations, allowing the effect of IS functions on LC to be evaluated. To validate the effectiveness of the ISS and the simulation method, we describe a case study that targets a new servitized business model with refrigerators. In the case study, we considered three patterns of LCs and two IS patterns with different functions for comparing the entire LCs and how the economic profit and environmental impact are changed depending on the difference in IS functions. In this case study, the IS and LC simulations identify how differences in IS functions affect the economic service provider’s profit, as well as the CO2 emission from the entire LC. Although our simulation method covers the entire LC, the functions of the IS focused on the use process in the case study. Therefore, further case studies targeting the LC processes, except the use process, are important for future work. In addition, developing methods for modeling and simulating the economic and environmental aspects of an IS is required.

Investigating the determinants of homestay satisfaction on Airbnb using multiple techniques

Peer-to-peer accommodation has gained prominence in the sharing economy and e-commerce sectors, with big data playing a crucial role in understanding customer preferences and evaluating homestay satisfaction. This study proposes a novel methodology that integrates Natural Language Processing (NLP) techniques, a Random Forest model, and Geographic Information System (GIS) functionalities to quantify the complex relationship between homestay satisfaction and diverse customer preferences. Notably, this study addresses the positive bias inherent in listing scores by segmenting homestays into three categories (satisfactory, moderate, and dissatisfactory) based on sentiment analysis from online reviews. Furthermore, this study not only identifies eight key determinants of homestay satisfaction but also unveils the nonlinear relationships and interactions between them. More significantly, we identify specific threshold values for geographic determinants, offering actionable recommendations for homestay planning and layout. These findings provide valuable insights that can be leveraged to improve homestay experiences and promote the sustainable development of urban homestays.

CLASSIFIERS OF DESTRUCTIVE IMPACTS IN DIGITAL SPACE

The digital format of public relations actualizes the issues of information security and information security. The article analyzes the normative acts containing the concepts of "destructive event" and "destructive action". They describe the sources of information threats emanating from man-made and anthropogenic sources and are associated with violations of confidentiality, accessibility and reliability of information, stability and reliability of information systems. The author came to the conclusion, as a result of the analysis conducted in the article, that the concept of "destructive actions" is more universal and defines the requirement not to take actions aimed at violating the information security of an information system and information. The concept of "destructive events" is used in a narrow technical area related to the disruption of the functioning of information systems at two levels of the OSI model - determining the route and addressing of data and communication between the endpoints of the transmitted data.

Analyze, monitoring and testing of computer information systems

The high importance and criticality of the efficiency and reliability of the functioning of modern computer information systems require efforts to ensure them, which are no less, than the efforts to develop the systems themselves. Offline and online monitoring and testing of computer information systems, which are often used to ensure efficiency and reliability of functioning, involve the development and implementation of appropriate hardware, software and information tools, as part of automated technical diagnostic systems. Features of both the computer information systems themselves and the means of monitoring and testing are their network distribution, autonomy and at the same time cooperation of all their components. Such features appear already in the system-functional presented systems and impose requirements for a special analysis of all their properties and functions, in that case also energy ones. The proposed work is focused on the implementation of energy-behavioral monitoring and testing of computer information systems, defines a formal presentation of a special analysis of the relevant hardware and software tools and is based on asynchronous-event models of extended Petri nets and behavioral experiments. This representation is based on models of energy-behavioral specification and testing, parallel, associative-evolutionary methods of monitoring and testing with the accumulation of blanks and results that differ in special features. The proposed presentation makes it possible to create a new system energy-behavioral technology for monitoring and testing computer information systems.

New Construction Laws

The new Construction Act became the object of interest of many lawyers and representatives of towns and municipalities. Despite many amendments, the original Construction Act is outdated, cumbersome and inflexible, and along with it, the Act on Spatial Planning and Amendments to certain Acts is changing. Thanks to the introduction of the Urbion information system, the issuance of construction permits will be speeded up and facilitated, and 13 of the 84 actions required to issue a building permit should remain. It interferes with the competences of municipalities, and even reduces their decision-making on their own spatial development. The contribution is devoted to the legislative changes in question and, in addition to the approximation of the functioning of the new Urbion information system, it also presents the opinions and attitudes of representatives of towns and municipalities in relation to spatial development and spatial planning.

Improving the Information and Legal Support of the Judicial System of Ukraine: Experience of the European Court of Human Rights

The research proposes a comprehensive approach to modernizing the information and legal support (ILS) of the judicial system of Ukraine, given European integration processes and the war of Russia against Ukraine. The need for substantial modernization of existing court automation systems to integrate with European systems and improve analytical capabilities for processing large data sets was identified. It was specified that the legal framework for the functioning of court information systems (IS) must be adapted to European legislation, and the organization of data warehouses and information flows must comply with EU standards. The principles of the functioning of court information systems should ensure the possibility of easy integration with the IS of the EU. To investigate war crimes committed by Russia in Ukraine, it is proposed to establish reliable ILS, given the case law of the European Court of Human Rights (ECHR) in cases of human rights violations during conflicts. An innovative approach based on the use of artificial intelligence (AI) tools is proposed to increase the efficiency of judicial decision analysis and improve the ILS of the judicial system of Ukraine. It has been proven that the integration of the judicial systems of Ukraine and the EU is possible, provided there are reliable data analysis tools, process standardization, digitalization, data security, and integrated registers. The effectiveness of applying IT tools in the ILS of courts has been confirmed. It is proposed to establish specialized hybrid courts in Ukraine with international experts to address war crimes, harmonize legislation with international law, and implement the case law of the ECHR.

ДОСЛІДЖЕННЯ КОНТЕКСТНО-ЧУТЛИВОГО АЛГОРИТМУ МОНІТОРИНГУ КІБЕРБЕЗПЕКИ НА ОСНОВІ РЕКУРЕНТНИХ НЕЙРОННИХ МЕРЕЖ

The most common problems faced by modern information and communication systems (ICS) in the context of combating cyber threats were examined in the paper. The importance of ensuring the reliable operation of ICS, and protecting their users' private data from unauthorized interception or destruction was emphasized. The main principles of effective protection of ICS systems against possible interference in their work were defined. The classification of cyber threats and their impact on the functioning of information systems was presented. Features of the use of modern information technologies were determined, such as machine learning (ML), and recurrent neural networks (RNN) for increasing the effectiveness of detecting and preventing such threats, speeding up the process of calculating large volumes of information about various aspects of the work of information and communication systems. The parameters of the analysis of ICS behavior, which indicate the presence of problems in cyber security, were studied. The features and advantages of deploying RNN in ICS were analyzed, which makes it possible to simplify the tasks of cyber defense. A modified context-sensitive algorithm for cyber security monitoring (CCM-RNN) was proposed, which is based on RNN and allows taking into account the dynamics of system changes in the established context, for example, the type or volume of traffic from users, etc. The method of selecting the most effective parameters and properties of ICS for detecting cyber threats was improved. The results of the study of the effectiveness of the use of the modified CCM-RNN algorithm demonstrated its broad capabilities for fast and accurate detection of anomalies in the operation of ICs that may threaten their cyber security. By changing the number of properties of the CCM-RNN algorithm, which correspond to the characteristics of various aspects of the IC, it is possible to achieve the maximum accuracy of cyber threat detection. The modified algorithm also allows for the reduction of the duration of calculations during analysis. Based on the research results, a conclusion was made about the feasibility of using the proposed modified CCM-RNN algorithm for the ability to detect cyber security threats in ICS by flexibly adjusting the number and type of learning parameters of neural networks. In this way, the accuracy and duration of calculations were optimized, as well as the peculiarities and contexts of information and communication systems were taken into account.

Spatial and Temporal Analysis of Road Traffic Accidents in Major Californian Cities Using a Geographic Information System

Road traffic accidents have increased globally, which has led to significant challenges to urban safety and public health. This concerning trend is also evident in California, where major cities have seen a rise in accidents. This research conducts a spatio-temporal analysis of traffic accidents across the four major Californian cities—Los Angeles, Sacramento, San Diego, and San Jose—over five years. It achieves this through an integration of Geographic Information System (GIS) functionalities (space–time cube analysis) with non-parametric statistical and spatial techniques (DBSCAN, KDE, and the Getis-Ord Gi* method). Our findings from the temporal analysis showed that the most accidents occurred in Los Angeles over five years, while San Diego and San Jose had the least occurrences. The severity maps showed that the majority of accidents in all cities were level 2. Moreover, spatio-temporal dynamics, captured via the space–time cube analysis, visualized significant accident hotspot locations. The clustering of accidents using DBSCAN verified the temporal and hotspot analysis results by showing areas with high accident rates and different clustering patterns. Additionally, integrating KDE with the population density and the Getis-Ord Gi* method explained the relationship between high-density regions and accident occurrences. The utilization of GIS-based analytical techniques in this study shows the complex interplay between accident occurrences, severity, and demographic factors. The insight gained from this study can be further used to implement effective data-driven road safety strategies.

Criterion of construction and strategy of functioning of information and telecommunication system with protection against destructive effects

The creation of information and telecommunication systems with the integration of information transmission, reception and processing functions determines the need to find technical solutions to ensure its security and protection while increasing the intensity of information processes, improving technologies for unauthorized access to information areas and creating destructive effects. Joint fulfillment of requirements for information security and maintaining operational properties of the system, which regulate efficiency, efficiency and resource intensity of information exchange, is achieved in accordance with a minimum-margin rule, the essence of which is to find the maximum possible information losses and determine a strategy for achieving minimum values of these losses. Within the framework of the used approach, the best solution is to establish a set of parameters of transmitting and receiving devices and information processing means with the lowest loss value of the target function of information exchange under the most dangerous and effective destructive effects. Goal – justification of the criterion for construction and strategy of functioning of the information and telecommunication system with protection against destructive effects. The criterion of construction and strategy of operation of the information and telecommunication system are justified in order to achieve the best probabilistic-time indicators of information exchange with a balanced set of measures to ensure security and information protection in case of destructive impacts. Due to the variety and variability of the conditions for the manifestation of destabilizing factors, the parameters and reconfiguration schemes of telecommunication channels, as well as the operating modes of information processing devices, were established while achieving the effectiveness of meeting the information needs of subscribers according to the optimality criterion and setting indicators of the efficiency and resource consumption of the system according to the suitability criterion. Possibilities and options for adaptive, situational and reflective control of the information and telecommunication system in the interests of rational distribution of the information resource to achieve target functions and the use of technologies for ensuring security and protecting information from destructive influences are investigated. Automatic control of the system is at the stage of prohibiting destructive effects on the information area by maintaining components in states that most fully correspond to the goals and objectives of information exchange. Situational control of information security during transmission and reception, used, as a rule, at an early stage of implementation of the conflict component in the information process, is based on the identification of destabilizing factors based on the results of classification of current states and neutralization of threats due to the restructuring of the system operation regulations carried out. Reflexive control, the strategy of which is based on prediction and evaluation of changes in the parameters of information processes under destructive effects, is in the form of transferring components of the information and telecommunication system to the state of its own information equilibrium, which helps to maximize the target function of information exchange while minimizing the performance indicators of destructive effects carried out. Due to the expediency of consistent implementation of the above control strategies in assessing the degree of occurrence of threats to the information process, the vector of parameters of information objects and telecommunication channels must from the conditions for neutralizing the full set of predicted destabilizing factors be determined. A reasonable criterion for building an information and telecommunication system makes it possible to jointly search for technical solutions for creating receiving and transmitting devices and information processing means in order to achieve maximum performance indicators of information exchange under established limitations of efficiency and resource intensity. The developed rule for selecting the strategy for controlling components of the information and telecommunication system establishes time-frequency and space-energy distributions of information processes necessary to meet the information needs of subscribers when transmitting, receiving and processing information in different conditions for the manifestation of destructive threats. The obtained results form a methodological basis for building information and telecommunication systems with protection of information coming through their channels with increasing requirements for target functions of information exchange and strengthening system restrictions due to improvement of technologies for unauthorized access to information areas and creation of destructive effects.

Classification of global information internal audit support systems

The creation and functioning of global information systems in economic management fully applies to such an area of economic activity as internal audit of business entities. However, the development of information systems is so rapid that a conventional IS audit is not enough to ensure effective functioning, therefore, the issue of computerization of internal audit is quite relevant and requires the development of an intelligent system to support the internal audit of business When analyzing research and publications, it was found that the disclosure of the main aspects of the use of computer technologies in conducting audit activities and automation of audit processes was best reflected by such scientists. Although the problem of the need for computerization of the audit undoubtedly meets the requirements of the time and has been studied by a certain circle of scientists, for a significant number of domestic business entities this problem still remains unresolved. An intelligent system can help with audit p rocesses and ensure the accuracy of the results of automation and the application of analytical tools. The development of an intelligent internal audit support system is an important and necessary task, as internal audit plays an important role in ensuring effective management and control of a business entity.

DIGITAL FINANCIAL ASSETS AND THEIR OPERATORS IN THE RUSSIAN FEDERATION

The relevance of the research topic is to consider the genesis of the legislative consolidation of the legal status of digital intermediaries, namely, the operator of the information system and the operator of the exchange of digital financial assets. The purpose of the study is to determine the role of an information system operator and a digital financial assets exchange operator in the Russian Federation. The scientific novelty of the article is manifested in the formulation of the provision that one of the main advantages of an information system based on a distributed registry is that the very technical properties of such a system allow for the issuance, accounting and circulation of digital financial assets without the participation of digital intermediaries due to the fact that this digital system already contains records of all changes being made, and therefore a priori is valid. Materials and methods. The paper presents an analysis of the current legislation, judicial practice and scientific doctrine on the problematic issue of the legal status of digital intermediaries – the operator of the information system and the operator of the exchange of digital financial assets. In addition, it provides comments on the relevant provisions of the digital financial assets Law. Results. In accordance with the legislation on the digital financial assets, the operator of an information system where digital financial assets are issued is recognized as a legal entity whose personal law is the Russian law and who is included in the register of information system operators by the Bank of Russia. The tasks of the information system operator mainly include ensuring the proper uninterrupted functioning of information systems. To complete the tasks, the information system operator must approve the rules of its information system and coordinate them with the Bank of Russia. Transactions permitted by the Russian law with the digital financial assets are made through the digital financial assets exchange operator, which collects and compares applications for such transactions or participates at its own expense in the transaction as a party in the interests of third parties. Digital financial assets exchange operators are credit organizations, trade organizers, as well as other legal entities that meet the requirements and are included by the Bank of Russia in the register of digital financial assets exchange operators. The theoretical and practical significance of the study consists in the identification by the authors of such a fundamental feature of the digital financial assets as non-mediation, which is a priori inherent in the digital financial assets, but, unfortunately, the Russian legislator rejected the corresponding legal regime of the digital financial assets. In this regard, third parties – digital intermediaries, namely the operator of the information system and the operator of the exchange of digital financial assets, are actually involved in the relations that are developing regarding the issuance, accounting and circulation of digital financial assets. Conclusions. The authors concluded on the basis of judicial practice that the viability of the legal norms considered in the article is questionable, since at the moment there are no disputes around the digital financial assets.

Altmetric functions of foreign current research information systems (CRIS-systems)

Altmetric methods enable to facilitate assessing research results on the basis of their citations and use by other users. The author addresses Current Research Information Systems (CRIS) as the core resources to reflect research output of individual research institutions. The purpose of her study is to analyze the experience of applying altmetrics in foreign CRIS. Besides, she reviews the studies in altmetrics and characterizes in brief altmetric indicators and their providers. Based on the analysis, the author suggests that Altmetric.com and Plum Analytics are the main source of altmetric data. Three groups of indicators are specified, namely: social metrics (twits, likes, reposts, comments), influence metrics (saving bookmarks and favorites, citing from different information resources, meeting a sustainable development goal), and use metrics (clicks, views, loads, library lending). The influence metrics is an alternative metric characteristic for foreign CRIS, as it is a sustainable development indicator based on the UN Sustainable Development Goals.

Cartographic Resources for Equitable University–Community Interaction in Slum Areas

Cartographic resources play a crucial role in facilitating communication across various sectors, including research projects focused on low-income communities. Despite this, some researchers still adhere to colonialist and exploitative approaches. This study aims to promote equitable university–community interaction though cartographic resources, aid academic and vulnerable community users in choosing a better platform for their work, and provide insights to developers for improving the platforms to better serve the user profiles of community members. To achieve this, we examined the use of cartographic resources in five projects within low-income communities (commonly referred to as favelas or so-called “slums”) in three Brazilian cities, all guided by equitable principles. The study unfolds in four stages: (i) data collection from documents and interviews; (ii) systematization into seven analytical categories—cartographic resources, data, personnel, processes, equipment, general objectives, and specific objectives; (iii) analysis of eight cartographic resources; and (iv) a critical examination of the outcomes. The synthesis of the collected information identified 65 characteristics/demands, with 17 common to all projects, including vector feature creation, thematic map design, printed map usage, and satellite imagery. We also identified 53 geographic information system (GIS) functionalities required for the projects, predominantly related to vector data generation and editing. The outcomes demonstrate the benefits of project methodologies, contributing to a decolonial university–community praxis. Additionally, they underscore the potential of digital cartographic resources, functioning not solely as data collection tools but also as powerful instruments that empower slum residents to advocate for improvements and foster local development.

Analysis of The Influence of Information System Applications, Digital Trainings and Technology Adoption on Financial Information System Performance

This study intends to investigate how top management support, user training programs, user technical skills, and technology advancements affect the performance of accounting information systems. This study is causal. The study's target demographic consists of retail enterprises implementing computerized systems. Data was gathered using the survey approach, which entailed sending out questionnaires. The sampling method employed is convenience sampling. Multiple linear regressions are employed in hypothesis testing. The study's findings support that technology advancements significantly impact how well the accounting information system functions. These findings align with earlier studies demonstrating how technological sophistication affects information systems' effectiveness, as determined by system utilization and user satisfaction. However, personal technical ability does not significantly influence its performance, in contrast to other research findings that show the opposite. User training programs and top management support have also been shown to dramatically influence AIS performance, following previous research indicating that training programs and management support can improve performance. Other variables not examined in this study explain most of the variation in AIS performance, suggesting the existence of different factors that also play an essential role in determining its performance.
