Opracowanie nawiązuje do ogólnych wymagań zapisanych w "Prawie ochrony środowiska", dotyczących oceny standardów jakości środowiska odnoszących się do emisji drgań pochodzących od eksploatowanych dróg. Podano tu procedury przydatne w ocenianiu wpływu na budynki eksploatowane drgań generowanych przejazdami pojazdów w pobliżu tych budynków. Drgania takie są wymuszeniem kinematycznym budynku i mogą doprowadzać do jego uszkodzeń (rysy, uszkodzenia elementów architektonicznych, zarysowania w elementach konstrukcyjnych itp.). Z kolei drgania w budynku mogą wpływać na naruszenie warunków niezbędnego komfortu wibracyjnego. Mogą też naruszać wymagania odnoszące się do warunków pracy urządzeń wrażliwych na drgania w budynkach eksploatowanych. Zadaniem rzeczoznawcy jest opracowanie diagnozy, w wyniku której uzyskuje się informacje o tym, czy istnieje związek skutkowo-przyczynowy między naruszeniem warunków bezpiecznej eksploatacji budynku a działaniem źródła drgań. Zastosowanie procedur tu opisanych powinno ułatwić wykonanie takich diagnoz. Postępując według podanych procedur rzeczoznawca będzie stosował odpowiednie narzędzia diagnostyczne, o których niezbędne informacje również zamieszczono w niniejszym opracowaniu.

The study refers to the general requirements of the Environmental Protection Law regarding the assessment of environmental quality standards relating to the emission of vibrations from the roads in use. The article discusses the useful procedures for assessing the impact of vibrations generated by passing vehicles near the buildings. Such vibrations are a kinematic excitation for the building and can lead to damage (Iike cracks, damage to architectural elements, scratches in structural elements, etc.). In turn, vibrations in the building may affect the violation of the conditions of the necessary vibration comfort. They may also violate the requirements relating to the working conditions of devices sensitive to vibrations in exploited buildings. The expert task is to develop a diagnosis, as a result of which information is obtained as to whether there is a cause-and-effect relationship between the violation of the conditions for the safe operation of the building and the operation of the source of vibration. The use of the procedures described here should facilitate such diagnoses. Following the given procedures, the expert will use appropriate diagnostic tools, and the necessary information described in this study.

Purpose: the main purpose of this article is to stimulate discussion on the following thesis presented in the article. Anticipating the process of just transition without taking into account demographic changes will incompletely reveal the social and economic effects caused by it. Design/methodology/approach: the research used the method of descriptive and comparative statistics, as well as literature review, critical analysis of literature, document research and comparative analysis. Findings: on the basis of the analyses and research carried out in this article, it can be concluded that in the examined areas of mining municipalities – in the part relating to the stream of labour supply – a dynamic process of ageing of labour resources is clearly noticeable. On the basis of the above conclusion, it seems that the need to subordinate the policies implemented in the city to the indicated process is justified. Originality/value: the entirety of the outlined changes, processes and forecasts indicates that in order to reduce the stratification in the examined areas, which is the main source of structural mismatches, it is necessary to undertake actions aimed at building future-oriented municipal policies – especially with regard to old age. Failure to take such measures in the perspective of social and economic transformation may delay preparation for the seemingly inevitable changes in the age structure of the population living in the studied areas of mining municipalities.

Content available On the Important Meaning of Bio-Liquid Dynamic Viscosity Variations in the Lubrication Flows
Wierzcholski Krzysztof, Gospodarczyk Jacek

nr 1
83--95
EN
The main topic of this paper refers to the numerous relations between the decrements of the dynamic viscosity of non-Newtonian bio-liquid lubricated human joints on the one hand and, on the other hand, with consequences resulting from various diseases such as low fitness and low skills of human limbs, joint unfitness, large wear of cooperating cartilage bio-surfaces. Additionally, this paper indicates the pharmacology methods performed in vivo to enhance the bio-liquid lubricant dynamic viscosity. After numerous experimental measurements, it directly follows that the collagen fibre, hyaluronate acid particle, power hydrogen ion concentration pH in lubricating bio-liquid and absorbability features of lubricated bio-surface have a direct and indirect significant influence on the bio-liquid dynamic viscosity values variations with interfacial energy distribution across the film thickness. The results presented in this paper are confirmed based on experimental measurements and analytical, numerical solutions of the load-carrying capacity, friction coefficient and bio-liquid dynamic variations performed for various human joints. These effects were simply disregarded in previous studies. The aforementioned problem has not been considered in contemporary research literature in the medical tribology domain to the Author's best knowledge. The results obtained should enable one to introduce more effective and accurate therapeutic protocols into the human joint treatment regimen. The results obtained have applications on a wide scale in spatiotemporal models in bio-tribology, biology and health science.

Główny temat pracy dotyczy licznych związków pomiędzy spadkiem lepkości dynamicznej nienewtonowskiej biocieczy smarującej stawy człowieka z jednej strony a konsekwencjami powodowanymi przez różne choroby z drugiej strony, takimi jak: mała sprawność oraz zręczność kończyn, brak sprawności stawów, znaczne zużycie powierzchni chrząstki. Niniejsza praca przedstawia dodatkowo farmakologiczne metody powiększania in vivo lepkości dynamicznej smarującej cieczy biologicznej. Z licznych eksperymentalnych pomiarów wynika, że włókna kolagenowe, cząsteczki kwasu hialuronowego, potęgowa koncentracja jonów wodorowych pH w biologicznej cieczy smarującej oraz właściwości absorbcji smarowanej powierzchni chrząstki, mają istotny pośredni i bezpośredni wpływ na zmiany lepkości dynamicznej oraz rozkład energii wewnętrznej w poprzek grubości warstwy cieczy biologicznej. Przedstawione w pracy rezultaty potwierdzone zostały na podstawie eksperymentalnych pomiarów oraz analityczno-numerycznych obliczeń siły nośnej, współczynnika tarcia, zmian lepkości dynamicznej smarującej cieczy biologicznej, przeprowadzonych dla różnych stawów człowieka. We wcześniejszych badaniach takie efekty były pomijane. Według informacji autorów, rozpatrywany problem nie był rozpatrywany we współczesnych badaniach literaturowych tribologii medycznej. Przedstawione rezultaty umożliwią wykonywanie bardziej dokładnych leczniczych protokołów w trakcie wykonywania zabiegów dla stawów człowieka. Wyniki uzyskane w pracy znajdują zastosowanie na szeroką skalę w czasowo-przestrzennych modelach biotribologii oraz nauki o zdrowiu.

The research considers the aspect of the formation of interior lightning in conditions of extensive expenses on heating. In this regard there is important to study features not only of places and model of lightning, but also generation of heat in order to minimize expenses and find alternative technical solutions for building functioning. The relevance is determined by the fact that the problem of low efficiency of thermal energy used to ensure an appropriate microclimate in buildings is typical for many regions. The purpose of this article is to study features not only of places and model of lighting but also generation of heat to minimize expenses and find alternative technical solutions for building functioning. In the work, the methods of calculation methods and mathematical models such as the exergy model of humans were used. The authors have determined that daylight is only one of the complex solutions of the matter of building energy efficiency. Providing the conditions of heating comfort indoors is not less important in the conditions of increasing requirements to energy conservation. The authors consider the compromise between these two requirements without harming human health the main challenge to the energy conservation specialists. The authors have developed the model, which evaluates not only the achievements of technical parameters, but also orientation toward the model of energy consumption of human. The practical application of the developed methodology allows for forecasting not only building heating based on projected technical indicators but also tailored to individual needs.

W artykule przedstawiono aspekty projektowania oświetlenia wewnętrznego w warunkach dużych nakładów na ogrzewanie. O trafności tematu decyduje fakt, że problem niskiej efektywności wykorzystania energii cieplnej w celu zapewnienia odpowiedniego mikroklimatu w budynkach jest typowy dla wielu regionów. Celem artykułu jest zbadanie cech nie tylko lokalizacji i modelu oświetlenia, ale także wydzielania ciepła, aby zminimalizować wydatki i znaleźć alternatywne rozwiązania techniczne dla funkcjonowania budynku. W pracy posłużono się metodami obliczeniowymi oraz modelami matematycznymi, takimi jak model egzergii człowieka. Ustalono, że światło dzienne to tylko jedno z kompleksowych rozwiązań kwestii energooszczędności budynków. Zapewnienie warunków komfortu cieplnego w pomieszczeniach jest równie ważne w obliczu rosnących wymagań dotyczących oszczędzania energii. Autorzy uważają, że kompromis między tymi dwoma wymogami bez szkody dla zdrowia ludzkiego jest głównym wyzwaniem dla specjalistów od oszczędzania energii. Opracowano model, który ocenia nie tylko osiągane parametry techniczne, ale także orientację na model zużycia energii przez człowieka. Praktyczne zastosowanie tej metodyki pozwala prognozować ogrzewanie budynku nie tylko na podstawie przewidywanych wskaźników technicznych, ale także z uwzględnieniem indywidualnych potrzeb.

Purpose: the main purpose of the article is to justify need for interdisciplinary professional training of employees for challenges related to the growing importance of dynamically developing automation, which is closely related to the pace of civilization development. Design/methodology/approach: the theses presented in the article have been verified using: literature review, critical literature analysis, document research and comparative analysis. Findings: based on content of this article, a future emerges in which man, industry and surrounding reality will be shaped by automation developing with a hitherto unknown dynamics. This phenomenon may lead to the disappearance of a world dominated by the industrial age and the transition to a new era determined by technologies, dominated by data flow and its analysis. In automated economies, knowledge that is exemplified by the knowledge society that creates innovative solutions has become a key capital. It seems that automation in the context of economies' competitiveness will determine the need to raise the level of education and of competences, and to create and control new knowledge. Originality/value: the article enriches knowledge and develops discussion in the area of dynamically developing automation. Thanks to the knowledge presented in the article, it can be concluded that the decisive role in creating the development of labor market and education can be overcome by breaking social and professional barriers to automation processes - which may favor the social dimension of the individual and strengthen the sense of human life fullness.

The publication presents the issues of philosophical anthropology fundamental for Leszek Kołakowski's interests, which attempt not only at finding answers but also asking questions about the condition of human nature, the constitutive conditions for human existence in the transcendental dimension, the essence of tensions and conflicts that may pose a threat to the survival of the European civilization, and, finally, questions about whether there are orientation marks and points of support that constitute the necessary conditions for its further existence and development. This area of concern places the human being at the heart of the matter as a causal being - taking action and endowed with freedom of will which presupposes the ability to do good and evil. Understood in this dimension, exceeding the features of zoological species, participates in the moral and cognitive sphere, in the sphere of unconditional moral imperatives, which cannot be empirically determined. Humanity transcends the properties of nature and is not defined by specific determinants that distinguish it from other species. Therefore, manhood is a moral notion, an attempt to make an endless intellectual effort to marginalize the natural instincts in order to convince people that the man is a moral being, a self-contained goal, not a means.

Sustainable development when understood as a process of social, economic and environmental change that ensures a balance between profit and development costs, is a kind of ethical project. The fundamental assumption behind the implementation of the idea of sustainable development is, therefore, the awareness of holding responsibility both in the context of actions of whole companies as well as individuals. The issue of responsibility covers many aspects and problems, hence, it is worth considering the concept of responsibility in its theoretical and practical dimension. The aim of this article is to present selected philosophical concepts of understanding responsibility.

In the paper, in an interdisciplinary way, an attempt was made to define the term "social innovation" in the context of strengthening active social policy and community organising. It appears that multifaceted tendencies and changes in the development of technological and social innovations determine the need to take into account numerous tasks, functions, needs, determinants and systematic efforts to ensure that community inhabitants have good living and development conditions.

This paper, based on literature research, reflects upon the importance of active social policy and labour market in the social and professional development of people aged 50 years and more. It seems that in the light of the conducted research, the formula of the social policy and labour policy market related to it has been exhausted. Therefore, it is necessary to develop a new policy model that will take sufficient account of the dominance in the elderly society and the need to sustain their social and professional activity as long as possible, while maintaining the idea of employment priority and education over benefits.

The article proposes a phenomenological model of a passenger car. The model includes the biomechanical model of human bodies in the sitting position of Muksian and Nash acting as passengers, while the driver’s weight has been reduced to the concentrated weight of the loading seat. The research carried out in this study consisted of passing the vehicle through a transverse obstacle along the so-called speed bump. Vehicle passes through the threshold at three different speeds: 10km/h, 20km/h, and 30km/h. The purpose of the conducted experiments was to initially estimate the values of accelerations acting especially on the passenger at selected driving speeds. On the basis of conducted tests, it was possible to verify the numerical model of the vehicle overcoming the obstacle on the road. This approach allows the use of the proposed model to verify the forces and accelerations affecting the passenger, specified before any selected specific biomechanical model of the human person, for example, a model of pregnant women in this configuration allows us to estimate the forces and accelerations acting on the embryo while overcoming some obstacles on the road.
