Purpose: The research objective of this thesis is to review the latest research in order to determine the form and content of ecolabels that will increase their effectiveness in environmental. Design/methodology/approach: A qualitative literature review was used in this study. It served to identify, evaluate and synthesise research relevant to the problem under consideration. The study adopted a systematic literature review methodology in accordance with the guidelines set out by Moher et al. (2009). Findings: The analysis of the research results identified during the systematic literature review process allowed us to identify elements related to the form and content of the ecolabel design. They were grouped into the following categories: visual design, scope of environmental information, accuracy of environmental information, adaptation to consumer segments, information relevant to the product, and presentation in online retail. These results indicate that designing an effective ecolabelling system requires treating it as a complex communication system. The effectiveness of ecolabels depends on many aspects and requires an integrated approach. However, any actions taken to achieve this are worth the maximum commitment of all market parties. Research limitations/implications: A limitation of the study is that the literature review is based on only one database, Scopus. Practical implications: The results of this study provide a valuable source of knowledge about the desired graphic and informational elements of ecolabels. This data may be relevant for regulatory bodies and certification bodies. This work has identified and described the components of ecolabels that are most desired by consumers, the practical implementation of which will contribute to increasing the effectiveness of environmental labelling. Originality/value: The paper presents an original and unique approach to the problem of research on the effectiveness of ecolabels. Based on a well-established and described method of systematic literature review, the latest research on ecolabels was identified and analysed.

The article presents the results of field tests and the analysis of the effectiveness of a “green wall” acoustic screen with an octagonal diffraction device. Insertion loss was assessed by an indirect method. The “pre‑installation” noise levels were measured at an equivalent location, next to the installed screen, where the terrain profile, reflective surfaces and ground surface did not change. An artificial, point and controlled sound source was used. In order to assess the effect of the diffraction device on the effectiveness of the screen, tests of the screen without the device were also carried out. The measurements were taken on the same day, under almost identical meteorological and acoustic conditions. In addition to experimental studies, numerical analysis was performed. Studies have shown that the diffraction device increases the effectiveness of the screen, especially at higher reception points, where the improvement was up to 6.8 dB. The results of measurements and calculations indicate a positive influence of the applied diffraction device on the effectiveness of the tested screen.

W artykule przedstawiono wyniki badań poligonowych i analizę skuteczności ekranu akustycznego typu „zielona ściana” z oktagonalną nakładką dyfrakcyjną. Skuteczność oceniono metodą pośrednią. Poziomy „przed instalacją” zmierzono w równoważnym miejscu, obok zainstalowanego ekranu, gdzie nie zmieniał się profil terenu, powierzchnie odbijające i powierzchnia gruntu. Zastosowano sztuczne, punktowe i kontrolowane źródło dźwięku. W celu oceny wpływu nakładki dyfrakcyjnej na skuteczność ekranu przeprowadzono także badania ekranu bez nakładki. Pomiary wykonano w tym samym dniu, w niemal identycznych warunkach meteorologicznych i akustycznych. Oprócz badań doświadczalnych przeprowadzono analizę numeryczną. Badania wykazały, że nakładka dyfrakcyjna zwiększa skuteczność ekranu, szczególnie w wyższych punktach odbioru, gdzie poprawa wyniosła do 6,8 dB. Zarówno wyniki pomiarów, jak i obliczeń, wskazują na pozytywny wpływ zastosowanej nakładki dyfrakcyjnej na efektywność badanego ekranu.

It is widely acknowledged that the expenses associated with substandard quality constitute a significant portion of a company's overall costs. Consequently, organizations adopt quality management systems and implement corrective and preventive measures to reduce these expenses. Within these implementations, Poka-Yoke (P-Y) techniques are notably prominent. Theoretically, these techniques are designed to prevent mistakes that lead to costs, especially quality-related costs associated with nonconforming products. This study proposes a classification graph of P-Y techniques, which serves as a tool for evaluating the effectiveness of these techniques in preventing errors that lead to product nonconformities, machine failures, operator injuries, or environmental threats. The Classification Graph was developed based on a study of 139 P-Y solutions implemented in 24 companies operating in the automotive, aviation, and metal processing industries. The value of this graph lies in its ability to easily evaluate and prioritize different P-Y techniques, aiding in the design of new techniques and the improvement of existing ones to enhance the reliability of production systems.

The article presents problems related to the detection of fire phenomena using convolutional neural network techniques. The main issue described in the article focuses on determining the precision of flame detection depending on lighting conditions and the selection of CNN architecture. The types of neural networks tested are primarily SSD architectures, which, with their speed of operation and energy consumption, are the most common in mobile applications. The study shows which of the neural network architectures used have the highest average precision in detecting the fire phenomenon. The selection of networks under testing was analyzed in terms of the speed of the algorithm and its precision. Four pre-trained neural network models were used during the testing of two training bases. The complexity of each model directly affected the training time of the model, which oscillated between 2-8 [h], and the precision achieved.

The dampness of the ground floors in buildings is generally a consequence of capillary rise of groundwater caused by the absence, damage or technical deterioration of the horizontal waterproofing of the masonry. Capillary absorption and damp transport are determined by the wetting properties of water relative to the material, as well as the structure and distribution of pores in the material. Chemical (injection) methods of secondary horizontal waterproofing are based on the technology of introducing injection liquid into the masonry section, which forms a lock which relies on the mechanism of capillary lumen constriction, hydrophilization, capillary sealing or a combined effect. A vital outcome of secondary horizontal waterproofing in a wall using the injection method is not only limited absorption but also its changed dynamics. The research paper describes the procedure leading to determining a criterion that allows to classify injection agents in terms of their impact on inhibiting capillary transport of damp in construction partitions.

The aim of the didactic and educational activity of every university, especially the military one, is to prepare the graduate intellectually and professionally to live in society. When creating educational programs in a specific field of knowledge or subject of education, it is assumed that their implementation will ensure that the teachers acquire the necessary minimum of required competences. In such a case, the authors of didactic programs always have a number of doubts or dilemmas such as: To what extent do the assumed competences correlate with the requirements and needs of the social reality, especially the professional one, in which the graduate is prepared to act? To what extent do the content of the curricula and the organization of the didactic and educational process ensure the acquisition of the assumed team of competences by the teachers? Of course, there are many more dilemmas of this type. Not all of them can be unequivocally resolved, if only due to the complexity of social situations in which the accuracy and reliability of the competences acquired by students are verified. Curricular education of students of military universities in the fields of study: national security, is aimed at, among others, the best possible preparation of future officers to command a sub-unit as well as managers and managers to manage human teams in state and local government institutions dealing with the organization and protection of public safety. An important element of the process of commanding a military sub-unit as well as managing in a situation of a potential threat is the ability to make accurate decisions as well as efficiently act and motivate subordinates and co-workers. In situations of uncertainty and insufficient information, and at the same time not only a potential but also a real threat to health and life, this requires not only appropriate psychophysical predispositions but also specific professional competences, especially in the area of distinguishing competences. Bearing the above in mind, the content and purpose of the article will be to introduce theoretically into the issues of social competences, seen from the perspective of a manager - leader - manager, and also an attempt to show the conditions of the manager's functioning - in various social situations, his role, tasks and qualifications, ensuring efficient management of the organization, these include: priorities in the implementation of tasks, skills, creative attitude and preparation for conducting negotiations. Requirements for modern managers - organization leaders - are extremely high, and meeting them does not guarantee only success. They lead people who, above all, need to be taught and prepared: to work in their position, to live in society, as well as to bring each other closer and focus around each other. Employees are different, they are strong and weak, full of pride and quite humble, curious about the world and, despite their different ages, overwhelmed by apathy. All of them, thanks to the work of managers and their competences, knowledge and skills, become good employees at various levels of the organization, and then managers. However, the basis of a manager's work is also, and perhaps above all, communication skills, the basis of which are negotiations.

The article contains selected results of comparative research on the quality of the parametric model, corrected in selected situations with the use of ANN and the Day-Ahead Market system of TGE S.A. carried out in MATLAB and Simulink. The System Identification Toolbox library was used for identification tests and Simulink for simulation and comparative tests. The comparative studies used such measures of model and system quality as: efficiency, effectiveness and robustness. Their waveforms as well as their average values and absolute errors and relative errors between the identification model or the identification-neural model and the system were obtained. The results of general tests were shown for the hours: 6:00, 12:00, 18:00 and 24:00 in 2019, and the detailed tests for 6:00. The sensitivity of the waveforms obtained in terms of model quality and the Day-Ahead Market system was also tested, depending on the assumed values of such parameters as e.g. electricity volume or volume-weighted average price of electricity.
