    Opis:
    Nowadays, the growth and complexity of functionalities of current information systems, especially dynamic, distributed and heterogeneous information systems, makes the design and creation of such systems a difficult task and at the same time, strategic for businesses. A very important stage of data protection in an information system is the creation of a high level model, independent of the software, satisfying the needs of system protection and security. The process of role engineering, i.e. the identification of roles and setting up in an organization is a complex task. The paper presents the modeling and design stages in the process of role engineering in the aspect of security schema development for information systems, in particular for dynamic, distributed information systems, based on the role concept and the usage concept. Such a schema is created first of all during the design phase of a system. Two actors should cooperate with each other in this creation process, the application developer and the security administrator, to determine the minimal set of user’s roles in agreement with the security constraints that guarantee the global security coherence of the system.

    Opis:
    To provide necessary quality of electric energy and reliable supply and reduce environmental contamination as a result of energy units operation, renewable sources of energy (RSE), in particular solar electric stations (SES), wind electric stations (WES) and small hydropower stations (SHES) are intensively developed. The paper considers the conditions of optimality of renewable sources of energy (RSE) functioning in electric systems, controllability of which is limited by the impact of non-stable weather conditions. The influence of control system information support on the efficiency of RSE usage is shown.

    Opis:
    A discrete-time stochastic control problem for general (nonlinear in state, control, observation and noise) models is considered. The same noise can enter into the state and into the observation equations, and the state/observation does not need to be affine with respect to the noise. Under mild assumptions the joint distribution function of the state/observation processes is obtained and used for computing the Gateaux and Frechet derivatives of the cost function. Under partial observation the control actions are restricted by the measurability requirement and we compute the Lagrange multiplier associated with this "information constraint". The multiplier is called a "dual", or "shadow" price, and in the literature of the subject is interpreted as an incremental value of information . The present and the future are two factors appearing in the multiplier and we study how they are balanced as time goes on. An algorithm for computing extremal controls in the spirit of R. Rishel (1985) is also obtained.

    Opis:
    A wide variety of soil and climatic conditions requires extensive study of the characteristics of the use of fertilizers and chemical plant protection products, which sometimes negatively affects the environment. Therefore, there is a need not only to know the ways and amount of application of fertilizers and chemical protectors but also to have a clear idea of the processes occurring in the soil, plants, ecology of the production environment and the rural population. This knowledge will allow us to carefully approach the practical issues of chemicalizing the crop industry and prevent possible negative consequences. To study the integrated interdisciplinary object of management accounting related to the assessment of the reproduction of agricultural land fertility, the functions and complex interaction of IT management, and analysis of specific situations of the impact of costs on fertilizers and chemical plant protection products on the gross crop production in the Kuban economic entities were applied. The study found that modern science has formulated the main theoretical aspects of the economic and environmental efficiency of the use of mineral fertilizers and chemical plant protection products in agriculture. Noting the significant achievements of scientists and practitioners in this field of agricultural development, we believe that the use of digital technologies for assessing the quality of soil fertility, methods and methods of using chemical agents can qualitatively improve information on the costs of their use, and determine the most rational and environmentally friendly areas. The studied experience in the application of methods indicates a fairly high accuracy in assessing the quality of soil fertility. Moreover, the results make it possible to change the associated types of managerial work, such as the planning of the procurement of fertilizers and plant protection products, precisely determine their types, and coordinate the place and time of their use.

    Opis:
    The study presents issues related to the motivation of human action and its shaping. The issues are presented from the point of view of psychology, sociology, management science and cybernetics. It was found that in the application of appropriate stimuli may affect motivation to change and consequently the change in quality of performance. The common denominator of these areas of study is the conclusion that the motivation may be the result of the conditions of information or energy. Maslow, human motivations, addicted from needs. He introduced the so-called pyramid of needs, from which it follows that the greatest impact of human motivations are the needs of an energetistic nature. But the Herzberg in his two-factor theory of motivation found that motivations are the result of exposure to man, so-call motivators such as stimuli (incentives) of the informative nature. At the same time he provided the conditions which made the effectiveness of these motivators. Mazur introduced the man as an autonomous system and describe the processes that determine the motivation of action. He said that the man, as the system must be able both to retrieve from environment as well to place on in to the environment, the information and energy. This means that the motives of human actions can have only informative and energetistic character, what largely corresponds with the results of sociological research. Kossecki linked motivations of human activities with distinctive social norms and depends of the human norm type, he found that motivations can be informative, energetistic, or mixed. To similar conclusions is reaching when it is depending the type of motivation of man's relation to the basic categories of social existence, given by Koneczny. Using the principles of transmission of information it has been shown that the efficiency of the control depends on the motivation. People with the energetistic motivation are more likely susceptible to control. In the discussion are presented examples of control in technical systems, typical for the problems presented in the work.
    W pracy przedstawiono zagadnienia związane z motywacją działań człowieka i jej kształtowaniem. Problematykę przedstawiono z punktu widzenia psychologii, socjologii, nauk o zarządzaniu oraz cybernetyki. Wspólnym mianownikiem wymienionych dziedzin nauki jest wnioskowanie, że motywacja może wynikać z przesłanek informacyjnych lub energetycznych. Masłow motywacje ludzkie uzależnił od potrzeb. Przedstawił tzw. piramidę potrzeb, z której wynika, że na motywacje człowieka największy wpływ mają potrzeby o charakterze energetycznym. Z kolei Herzberg w swojej dwuczynnikowej teorii motywacji stwierdził, że motywacje są wynikiem oddziaływania na człowieka tzw. motywatorów, tj. bodźców o charakterze informacyjnym. Jednocześnie przedstawił warunki, od których uzależnił skuteczność tych motywatorów. Mazur przedstawił człowieka jako system autonomiczny oraz opisał procesy determinujące motywacje działań. Stwierdził, że człowiek jako system musi mieć możliwość zarówno pobierania z otoczenia jak i wprowadzania do niego informacji oraz energii. Oznacza to, że motywacje działań człowieka mogą mieć tylko charakter informacyjno-energetyczny, co w dużym stopniu koresponduje z wynikami badań socjologicznych. Kossecki powiązał motywacje działań człowieka z charakterystycznymi normami społecznymi i w zależności od normotypu człowieka stwierdził, że motywacje mogą mieć charakter informacyjny, energetyczny lub mieszany. Do podobnych wniosków dochodzi się uzależniając typ motywacji od stosunku człowieka do podstawowych kategorii bytu społecznego, podanych przez Konecznego. Posługując się zasadami przekazywania informacji pokazano, że skuteczność sterowania zależy od rodzaju motywacji.

    Opis:
    Industrial processes’ control systems based on PLC controllers play today a very important role in all fields of transport, including also sea transport. Construction of control systems is the field of engineering, which has been continuously evolving towards maximum simplification of system design path. Up to date the time needed for system construction from the design to commissioning had to be divided into a few stages. A mistake made in an earlier stage caused that in most cases the next stages had to be started anew. Modern software allows for quicker implementation of system design. Available debugging systems allow for defect detection at an early stage of project implementation. Application of additional protective devices will allow for remote diagnosing of the equipment state and introducing changes (depending on authorities granted). The paper presents general characteristic of integrated software for implementation of complex control systems. The issues related to the software use for programming of the visualisation environment, control computer, selection of transmission medium and transmission protocol as well as PLC controllers’ configuration, software and control have been analysed.

    Opis:
    The objective of this paper is to define the dimensions of the function of information provision of tax authorities in public levies management. Accomplishment of the objective is based on the example of Poland, however the outcome may be applied intersubjectively in various models of tax administration all over the world. Critical review of the relevant literature has been employed as a methodological basis in combination with gradual concretization and comparative analysis as part of making inferences. It has also been assumed that the function of information provision of tax authorities is composed of an internal part as well as an external one, which is being developed on the level: tax authorities – tax management bodies. Therefore, a research hypothesis has been put forward stating that the function of information provision of tax authorities is heavily deformed, carried out selectively, and with no reflection on performance. The obtained research results testify to that and allow to indicate that the dimensions of this function overlap and not always co-contribute to subsidiarity in meeting tax obligations and simultaneously state interventionism marked by penalization of criminal offences. An undoubted theoretical contribution is a proposition of the dimensions of the function of information provision of tax authorities, enriched with possibilities for different management of intellectual capital as well as execution of the law on public levies. The results of this study may be of use to broadly defined tax administration, students, and researchers studying socioeconomic processes.

    Opis:
    Automation of data processing of contactless diagnostics (detection) of the technical condition of the majority of nodes and aggregates of railway transport (RWT) minimizes the damage from failures of these systems in operating modes. This becomes possible due to the rapid detection of serious defects at the stage of their origin. Basically, in practice, the control of the technical condition of the nodes and aggregates of the RWT is carried out during scheduled repairs. It is not always possible to identify incipient defects. Consequently, it is not always possible to warn personnel (machinists, repairmen, etc.) of significant damage to the RWT systems until their complete failure. The difficulties of obtaining diagnostic information is that there is interdependence between the main nodes of the RWT. This means that if physical damage occurs at any of the RWT nodes, in other nodes there can also occur malfunctions. As the main way to improve the efficiency of state detection of the nodes and aggregates of RWT, we see the direction of giving the adaptability property for an automated data processing system from various contactless diagnostic information removal systems. The global purpose can be achieved, in particular, through the use of machine learning methods and failure recognition (recognition objects). In order to improve the operational reliability and service life of the main nodes and aggregates of RWT, there are proposed an appropriate model and algorithm of machine learning of the operator control system of nodes and aggregates. It is proposed to use the Shannon normalized entropy measure and the Kullback-Leibler distance information criterion as a criterion of the learning effectiveness of the automated detection system and operator node state control of RWT. The article describes the application of the proposed method on the example of an automatic detection system (ADS) of the state of a traction motor of an electric locomotive. There are given the test data of the model and algorithm in the MATLAB environment.

    Autorzy artykułu dokonują przeglądu i systematyzacji działań Rady Europy w zapewnianiu jednego z kluczowych czynników demokracji liberalnej – wolności słowa, która jest warunkiem realizacji szeregu innych praw i wolności. Autorzy kategoryzują podstawowe dokumenty, zarówno te, które już stały się klasyką, jak i te przyjęte niedawno, w których zjawisko to uległo utrwaleniu prawnemu. W artykule zbadano, w jaki sposób wpływa ono na kształtowanie i rozwój prawa człowieka do informacji w Europie. Zwraca się uwagę na fakt, że wraz z pojawieniem się nowych sposobów rozpowszechniania informacji, w tym przede wszystkim wobec potencjału internetu, oraz gromadzeniem informacji i wysiłkami społeczeństw Europejskiej na rzecz ochrony tego podstawowego w demokracji prawa, jego dalsze wzmacnianie pozostaje istotną kwestią. Rada Europy utraciła kontrolę nad przestrzeganiem prawa człowieka do informacji, a informacje są wykorzystywane w destrukcyjnych celach, co stanowi zagrożenie dla jednej z fundamentalnych wartości, na podstawie których funkcjonuje dziś społeczeństwo europejskie zwiększając ryzyko przywrócenia autorytaryzmu. Autorytaryzmem zagrożone są przede wszystkim nowe demokracje Europy Wschodniej. Światowa pandemia COVID-19 i światowa recesja gospodarcza, w wyniku której obywatele chętniej wybierają autorytarnych przywódców, może być przyczyną wprowadzenia autorytaryzmu.
    In the article, the authors review and systematize the activities of the Council of Europe in ensuring one of the key factors of liberal democracy – freedom of expression, which is a prerequisite for the implementation of a number of other rights and freedoms. The authors categorize the basic documents, both those that have already become classics and those adopted recently, where this phenomenon has found legal consolidation. It studies the way in which it affects the formation and development of the human right to information in Europe. Attention is drawn to the fact that, with the emergence of new ways of disseminating information, including the potential of the internet first and foremost, the accumulation of information and the European community’s efforts to protect this fundamental democratic right, its further strengthening remains urgent. The Council of Europe has lost control over the observance of the human right to information, and information is used with destructive intent, which poses a danger to one of the fundamental values on the basis of which European society operates today, and raises the risk of the restoration of authoritarianism. First and foremost, there is a threat of authoritarianism in the new democracies of Eastern Europe. The global COVID-19 pandemic and the recession of the world economy, which encourages citizens to choose authoritarian leaders, may be the trigger for slipping into authoritarianism.

    Opis:
    The paper presents some aspects of a development project related to Industry 4.0 that was executed at Nemak, a leading manufacturer of the aluminium castings for the automotive industry, in its high pressure die casting foundry in Poland. The developed data analytics system aims at predicting the casting quality basing on the production data. The objective is to use these data for optimizing process parameters to raise the products’ quality as well as to improve the productivity. Characterization of the production data including the recorded process parameters and the role of mechanical properties of the castings as the process outputs is presented. The system incorporates advanced data analytics and computation tools based on the analysis of variance (ANOVA) and applying an MS Excel platform. It enables the foundry engineers and operators finding the most efficient process variables to ensure high mechanical properties of the aluminium engine block castings. The main features of the system are explained and illustrated by appropriate graphs. Chances and threats connected with applications of the data-driven modelling in die casting are discussed.

    The purpose of this paper was to develop a methodology for diagnosing the causes of die-casting defects based on advanced modelling, to correctly diagnose and identify process parameters that have a significant impact on product defect generation, optimize the process parameters and rise the products’ quality, thereby improving the manufacturing process efficiency. The industrial data used for modelling came from foundry being a leading manufacturer of the high-pressure die-casting production process of aluminum cylinder blocks for the world's leading automotive brands. The paper presents some aspects related to data analytics in the era of Industry 4.0. and Smart Factory concepts. The methodology includes computation tools for advanced data analysis and modelling, such as ANOVA (analysis of variance), ANN (artificial neural networks) both applied on the Statistica platform, then gradient and evolutionary optimization methods applied in MS Excel program’s Solver add-in. The main features of the presented methodology are explained and presented in tables and illustrated with appropriate graphs. All opportunities and risks of implementing data-driven modelling systems in high-pressure die-casting processes have been considered.
