Opis:
The investigations concerned sites of Acer platanoides L. infected or not by Rhytisma aceriniu (Pers.) Fr. The aim of the study was to check the occurrence of R. acerinium, and whether it reflects the environmental status. Furthermore, an analysis was carried out to find out whether the applied SOFM offers additional advantages to solve problems in relation to conventional methods. Concentrations of selected elements in soils and leaves, and leaf and "tar-spot" morphometric traits were also measured. A significant differentiation was found between sites in relation to the analyzed traits. It appeared, that sites showing lower concentrations of chemical elements and proper developmental habitat conditions massive infections take place. The study showed that R. acerinium is a good biological indicator for assessment of environmental status. The applied, conventional statistical methods, SOFM and image techniques showed similar, but not identical results for assessment of environmental quality using R. acerinium. SOFM appeared to be more useful for ordination of results and ought to be taken into account as a proper tool of estimation of various plants and their biotopes.

Opis:
The article aims to identify and quantify significant economic factors that determine the quality of the business environment in small and medium-sized enterprises (SMEs) in the transport and services segment. The case study was carried out on a sample of 258 companies in the Czech Republic and Slovakia. Statistical methods, such as regression analysis and correlation analysis, were used to evaluate empirical data. These statistical methods test and verify several statistical hypotheses formulated. The results of the case study brought interesting findings. Findings showed the impact of the macroeconomic environment on the quality of the business environment. Conversely, monetary policy and interest rates, corporate finance, and population’s consumption do not affect the quality of the business environment in the transport and services segment. The results also represent an essential basis for organizations supporting the business environment or for state institutions in the creation of materials for improving services or transport in the selected countries.
Artykuł ma na celu identyfikację i kwantyfikację istotnych czynników ekonomicznych, które determinują jakość otoczenia biznesowego w małych i średnich przedsiębiorstwach (MŚP) w segmencie transportu i usług. Studium przypadku zostało przeprowadzone na próbie 258 firm w Czechach i na Słowacji. Do oceny danych empirycznych zastosowano metody statystyczne, takie jak analiza regresji i analiza korelacji. Te metody statystyczne testują i weryfikują kilka sformułowanych hipotez statystycznych. Wyniki studium przypadku przyniosły interesujące ustalenia. Wyniki pokazały wpływ otoczenia makroekonomicznego na jakość otoczenia biznesowego. I odwrotnie, polityka pieniężna i stopy procentowe, finanse przedsiębiorstw i konsumpcja ludności nie wpływają na jakość otoczenia biznesowego w segmencie transportu i usług. Wyniki stanowią również istotną podstawę dla organizacji wspierających otoczenie biznesu lub dla instytucji państwowych w tworzeniu materiałów do doskonalenia usług lub transportu w wybranych krajach.

Opis:
Problems related to sustainable development concern a number of scientific disciplines, including architecture and urbanism which seek ecological solutions. On account of the development of civilization, we can observe numerous achievements in the field of science and technology on one hand. On the other hand, this development leads to the intensifying degradation of the natural environment, the destruction and reduction of biologically active areas, increasing air, water and soil pollution, rising traffic intensity and noise level etc. These serious problems have been piling up for years in spite of all the efforts and expenditures. With a view to the deteriorating living conditions and quality of the environment, the European Urbanism Council issued the New Athens Charter in 2003. This document opposes unfavourable social, political, economic and technological changes as well as those which take place in the natural and urban environment. A new outlook on the dwelling environment brings us closer to the concept of an ideal city – the 21st-century city dominated by the need to implement the principles of sustainable development; a housing environment which satisfies human needs without destroying Nature. This paper presents the results of research carried out in the central zones of small towns in the Province of Podkarpacie, located in southeastern Poland. To a certain extent, the selected towns realize the principles of sustainable development – among other aspects, they support a healthy housing environment, facilitate contact with green spaces as well as meet the requirements of access to primary services and cultural goods.
Problematyka zrównoważonego rozwoju dotyczy dyscyplin naukowych, w tym także architektury i urbanistyki, która zwraca się ku rozwiązaniom z zakresu ekologii. Rozwój cywilizacyjny z jednej strony skutkuje licznymi osiagnięciami nauki i techniki, a z drugiej – prowadzi do coraz większej degradacji środowiska naturalnego, niszczenia i redukcji obszarów biologicznie czynnych, wzrostu zanieczyszczenia powietrza, wody i gleby, natężenia ruchu i hałasu itp. Problemy te są niezwykle poważne, od wielu już lat obserwuje się ich narastanie pomimo czynionych wysiłków i ponoszonych nakładów finansowych. Ze względu na pogarszające się warunki życia i jakość środowiska Europejska Rada Urbanistów w 2003 r. opublikowała dokument zatytułowany Nowa Karta Ateńska, w którym nakreślono strategię przeciwstawienia się niekorzystnym zmianom: środowiska naturalnego i miejskiego, społecznym i politycznym, ekonomicznym i technologicznym. Nowe spojrzenie na środowisko zamieszkania przybliża nam koncepcję miasta idealnego, miasta XXI wieku, w którym wcielane w życie będą zasady rozwoju zrównoważonego, środowiska zamieszkania, w którym potrzeby człowieka będą zaspokajane, ale nie kosztem przyrody. W pracy przedstawione zostały wyniki badań przeprowadzonych w strefach centralnych niewielkich miast województwa podkarpackiego w południowo-wschodniej Polsce. Wybrane miasta realizują w pewnym zakresie zasady rozwoju zrównoważonego, w tym między innymi wspierają zdrowe środowisko zamieszkania, zapewniając kontakt z przestrzeniami zielonymi przy spełnieniu wymogów dostępu do usług podstawowych oraz dóbr kultury.

Opis:
The implementation of environmental issues in planning and designing urban structures is becoming a novel approach and a common practice consistent with the paradigm of sustainable development. Maintaining environmental quality in urban areas, managing natural resources and understanding the complexity of urban systems is becoming increasingly challenging. Therefore, it is important to develop strategies for the integration of environmental quality research into urban planning policies and for the development of alternative spatial solutions for the existing urban structure which are aimed at improving environmental quality in urban areas. The aim of the article is to review contemporary theoretical and practical approaches towards the implementation of environmental issues within the process of urban planning in order to present a framework for local planning policies. Described is the research into spatial and design solutions which can efficiently reduce noise levels, mitigate atmospheric pollution and odour nuisance or prevent the negative effects of local microclimate effect. The possibility of application of design guidelines aimed at achieving environmental objectives in local planning documents is also assessed.

In the soil environment, there are many enzymeswhose origin is related to microorganisms. Enzymes participatein the synthesis of proteins and nucleic acids, they are also elementsof the carbon, nitrogen and phosphorus cycles. They alsoplay a role in less known cycles, such as the sulphur cycle orcellulose decomposition. Determination of soil enzymes activityis very popular in microbiology, biochemistry and agriculturalsciences. Their activity may be a measure of soil fertility. Thepresent report describes the importance of selected soil enzymesand the methods of their determination. However, it is importantto remember that a single enzyme cannot be an indicator of theenvironment. The enzymatic activity is sensitive to many naturaland anthropogenic factors affecting soil microorganisms. Onlycomprehensive researchers on the activity of many, different enzymescan provide reliable information on the state of the soilenvironment.

Opis:
Creation of the built environment and research in this field pose a particularly difficult challenge nowadays. The pace of social and technological change does not allow for evolutionary development of cities and the formation of their land use according to current conditions. Creating spatial solutions that are unmatched in their contexts is becoming not only possible, but very probable (see Alexander, 1964). The development of the built environment involves not only art, technology, history, economics and law, but also philosophy, culture, medicine, psychology, sociology and many other spheres in which human life is manifested. However, only a relatively small number of disciplines such as spatial planning, urban design, urban planning, etc. (ignoring at this point the differences in the meaning of the concepts) in their application layer are meant to create space and bear responsibility for it. Also society has certain requirements of practical nature towards them.This article attempts to outline the nature of research on space urbanised by people and to determine the four main fields of research aimed at the problems of man and the built environment. In the next part, particular attention is paid to issues related to the impact of the built environment on the life of its residents in order to highlight the particular role and complexity of this area of research. This study, acting as a kind of test of the research, cannot be considered representative. Nevertheless, the analysis prompts several reflections on the current and future role of the built environment in the development of our civilisation, as well as further challenges related to it.

The aim of this research was to indicate the possibilities of using synthetic measure to find and analyse spatial disparities of the natural environment in 102 diagnostic communities of the Świętokrzyskie Voivodeship as a peripheral area. The research was conducted on the basis of selected diagnostic features. The data presented refer to the years 2009, 2012 and 2015 and come from the Local Data Bank. Bearing in mind the research aim, the following hypothesis was formed: The use of proper synthetic measures makes it possible to recognise spatial disparities which appear in the natural environment. This paper is a continuation of the work entitled: Synyhetic Measure Used as Assessment of Spatial Disparities of the Natural Environment (Przybytniowski, Dziekański, 2019). The analysis of the natural environment of municipalities occurs through human activities, and having a direct impact on the environment (indirectly related to the environment).

One of important factors of attractiveness of a region is its natural environment, namely a set of natural elements which are of interest to a tourist. In terms of economy, it is a source of raw materials and energy, it ensures geographical space, business opportunities and a place to live and relax. The aim of the research included in this article is to indicate the possibility of using synthetic measurement to recognize spatial disparities of the natural environment on the basis of selected diagnostic features of 102 municipalities of the Świętokrzyskie Voivodeship. The data presented in this article refer to 2009, 2012 and 2015 and come from the Local Data Bank. The following variables were selected: the total use of household water per one inhabitant, the distribution network per 100 km2 - water pipe system, the distribution network per 100 km2 – sewage system, woodland area, areas protected by law, protected monuments. The elements indicated refer to entities which function and operate in a territorial unit. The methods presented enable us to identify areas of human life (or human impact on the environment) of higher/lower efficiency (which depends on the level of synthetic measure) and, then, programme their support from public funds within the framework of the regional policy.

Opis:
Nowadays, one of the most important and essential aspects of having a healthy and safe life is the air safety and its quality in indoor and outdoor environments. In the air, there are not only chemical pollutants but also biological ones, with specific impacts. Hospital environments are among the most likely to be affected by the microbiological contamination of the air; therefore its quality is particularly important. Pathogenic microorganisms, which may be present in the air, can cause nosocomial infections in hospitalized patients, with compromised immune system or other medical conditions. This paper reflects the evaluation of microbiological air contamination, in different hospital environments and nearby areas, in the city of Tirana. The microbial air quality has been monitored during the period of 2009–2018, performing evaluations every three years, in the same area and the same time of the year. In order to build a database for understanding the impact of developmental changes on the air microbiological loads, results of similar studies conducted earlier, during 2007 and 2008 were also taken into consideration. The above-mentioned period was selected because of the changes in the infrastructure and indoor environments of the monitored area, where many patients have been treated for years. Changes have been made over the years to hospital structures and surroundings, including recreational facilities, clinical service units, as well as main and connecting roads, etc. The obtained results, which were compared over the years, provided a clear view of the changing microbiological air loads, influenced by the improvements of indoor and outdoor areas. The morphological studies of the observed, isolated, purified and identified microorganisms revealed the presence of specific mold loads, with the dominance of the species of Aspergillus genus and those of the group Fungi imperfecti. Over the years, a decrease in the total number was observed (from 103 to 101), together with a smaller number of bacteria (1012), in the monitored environments.

Subject and purpose of work: The subject of the study is the cooperation of secondary vocational schools (technical secondary schools) with institutions of the local environment and its impact on the improvement of the quality of education. The aim of the work is to identify the main results of the school's cooperation with its immediate environment. An important element of the analysis is to find answers to several problematic questions, such as: What institutions and organizations do vocational schools cooperate with? What activities are undertaken in cooperation with institutions and organizations? What educational benefits do school students get from cooperation? Materials and methods: The article uses a diagnostic survey method, an observation method, an inductive-deductive method, an interview and a literature review. The survey conducted among students and teachers of a selected secondary school made it possible to obtain information on the forms of cooperation with the local community and its impact on the processes taking place at school, in particular on the didactic and educational process. Results: The school teaching staff members see the need for active cooperation with the local community because entities from the school's environment can complement the didactic and educational activities. Therefore, numerous and varied forms of cooperation are undertaken, which, in the opinion of students, bring many benefits related to extending knowledge, improving professional skills and social competences. Conclusions: The cooperation of the school with the local community leads to the improvement of the quality of education, both in the area of didactics and education, as well as modernization of the didactic base and promotion of the school. It is advisable to consciously shape the cooperation by the school management.

Opis:
The quality of the aquatic environment of high Andean lagoons was evaluated by means of multivariate statistical methods in two contrasting climatic periods. The water samples and benthic macroinvertebrates were collected in 22 sampling sites during the rainy and dry seasons. In each lagoon DO, DTS, EC, temperature and pH were determined in situ. The results revealed that the physicochemical parameters comply with the environmental quality standards for water, except COD and BOD5. In the PCA of the physicochemical parameters, the first two axes explained 73% of the total variation. The gradual analysis in pairs showed significant differences. The SIMPER analysis determined an average of four families of benthic macroinvertebrates per lagoon that showed more than 70% contribution. The ANOSIM revealed that Tragadero lagoon differs significantly from the others. The DistLM showed a value of 0.46 of coefficient of determination. Therefore, the quality of the environment of high Andean lagoons evaluated by means of multivariate statistical methods presents important differences or dissimilarities not only in the physicochemical characteristics of the water, but also in the composition of the benthic macroinvertebrate communities.

Opis:
Today, one of the most topical issues related to the quality and safety of life on Earth is the monitoring of air quality in terms of its pollution that is harmful to human health and life. The activities undertaken as part of monitoring carried out include, among others, analysis of the composition of exhaust fumes from emission sources, such as households and industrial entities, in terms of the presence therein of potentially hazardous substances, indirectly in order to detect violations of the applicable environmental standards. In order to conduct this type of analysis, unmanned aerial systems are commonly used, which allow sampling in the immediate vicinity of the emission source. However, the currently functioning solutions do not allow for exhaust fume sampling in a way that allows a mixture for testing to be taken directly from an emission source. This leads to questioning of the reliability of the conducted research, as it is uncertain in terms of the origin of the tested mixture, indicating that the test takes place not at the source of the emission, but in its surroundings. This study proposes a technical solution to sample exhaust fumes directly from the emission source - from the interior of chimney openings.

Opis:
From a management perspective, water quality is determined by the desired end use. Water intended for leisure, drinking water, and the habitat of aquatic organisms requires higher levels of purity. In contrast, the quality standards of water used for hydraulic energy production are much less important. The main objective of this work is focused on the development of an evaluation system dealing with supervised classification of the physicochemical quality of the water surface in the Moulouya River through the use of artificial intelligence. A graphical interface under Matlab 2015 is presented. The latter makes it possible to create a classification model based on artificial neural networks of the multilayer perceptron type (ANN-MLP). Several configurations were tested during this study. The configuration [9 8 3] retained gives a coefficient of determination close to the unit with a minimum error value during the test phase. This study highlights the capacity of the classification model based on artificial neural networks of the multilayer perceptron type (ANN-MLP) proposed for the supervised classification of the different water quality classes, determined by the calculation of the system for assessing the quality of surface water (SEQ-water) at the level of the Moulouya River catchment area, with an overall classification rate equal to 98.5% and a classification rate during the test phase equal to 100%.
