Published: April 2023

The western area of Romania, like the entire country, due to its geographical position - in the temperate zone, is exposed to a wide range of risk weather and climate phenomena with the potential to occur throughout the year. The purpose of this work is to identify some indicators that most correctly express the extreme nature of the manifestations of some meteorological parameters and their characterization over a four-year period.
The paper analyzes the main meteorological parameters from the profile stations in the western part of the country, respectively from Timis and Arad counties, in order to have an overview of the weather-climate characteristics for the studied period. The more detailed analysis of certain phenomena was done to capture exceptions, special extreme situations or more significant meteorological elements. The location of Romania in a certain context of action of the main baric centers imprints the temperate character of the climate. The location of the analyzed territory in the western part of the country and the configuration of the relief nuance this character, imprinting sub-Mediterranean characteristics in the southern part of Timis county. The risk aspects provided by the weather stations in the two studied counties, in the interval of four years, highlight the specific climatic changes that occur in certain intervals.
Knowing the weather-climate characteristics of the region is important for all areas of human activity and life, all extreme phenomena being grafted onto the main background of the aforementioned weather-climate characteristics.

The problem of carbon dioxide emission from the soil is relevant, since it affects the reduction of the soil organic carbon pool, thereby reducing its fertility and productivity. In addition, carbon dioxide emissions from the soil are a significant contributor to the greenhouse effect. The aim of this work was to evaluate the mineralizing activity of the microbial community of the soil of a new point of observation of carbon dioxide emissions, located in the previously little-studied territory of Russia, using such parameters as respiration activity, microbial biomass, and the number of copies of bacterial and fungal genes. The highest values of respiration activity and microbial biomass of the studied soil were 2.3*10-4 mgCO2*g-1*h-1 and 0.48 mg*kg-1 and were observed on 26.07.2022 and 15.06.2022, respectively. The maximum number of gene copies of bacteria and fungi in the soil was 6*106 (15.06.2022) and 3.78*104 (15.06.2022) gene copies*g-1, respectively. It was revealed that the respiration activity of the soil depended on the air temperature and soil moisture, while the microbial biomass depended mainly on the air temperature.

Authors: Titko Michal , Studena Jana
Published: April 2023

Disasters and extreme weather events currently have a growing tendency in the frequency of occurrence and also in the severity of the impacts. The main cause is climate change, the manifestations of which will become more and more extreme. The costs of dealing with natural disasters and the consequences of extreme weather events in terms of loss of life and damage to social, economic and environmental assets are expected to become increasingly high. The current situation therefore requires a prompt reaction and a change of attitudes towards the given issue, mainly from the point of view of the state, but also of the population itself. The article examines the attitudes of the population towards climate change and analyses (1) people-s perception of the need to implement adaptation measures and (2) barriers to adaptation to climate change. For the analysis are used the questionnaire survey results. Initial results indicate that the adaptation measures of the population are affected by various barriers, but in the long term, the respondents consider the need for adaptation to be important.

THE NARRATIVE OF CLIMATE CHANGE IN LATVIAN MEDIA CONTENT
Authors: Skulte Ilva
Published: April 2023

The mass media are important actors in the conceptualization of the problems and possible solutions related to climate change. They have an opportunity to master the agenda and formulate it not only in all importance and complexity but also in the diversity of aspects to be included for proper understanding of the climate change concept by the public. In doing so they build on existing agendas by policymakers, scholars, and other actors, but also have their agency to be exercised in all responsibility and by specific knowledge. The overall task for media is to build a consistent and coherent narrative that will serve as a base for understanding current issues. However, analysis of Latvian media shows that a vast number of publications tend to speak about climate change in general terms, without being devoted to a particular domain of issues. The results on the dynamics of publication and reach of the audience of the content can be interpreted by discerning three general groups of climate change-related issues. The first group of related issues is mentioned more in connection with political agenda (e.g. COP26). The second group of issues (emissions, green energy, carbon neutrality/decarbonization) are proposed by industries and businesses dealing with them but are rather little known to the general public. Opposite, the third group includes keywords like environmental protection, protection of nature, and natural diversity that are familiar to most people; they have a stable place but are not very popular in the content of media.

Published: April 2023

The evolution of technology in the field of unmanned aerial vehicles (UAVs) has led to the miniaturization of the equipment on board these aircraft. The most used equipment mounted on a UAV is still the video sensor, with the help of which the video image from the aerial vehicle can be processed for dedicated applications (facility inspection, surveying and mapping, operational oversight, traffic control, etc.). In this paper, we present the prototyping of a three-axis gimbal using the direct drive technology to replace the current two-axis gimbal payload equipping our Hirrus UAV. The results demonstrate notable improvements both mechanically, by excluding the gearing of the transmission belt (generating friction and elasticity in the system), and in terms of video resolution, maintaining quality especially at high zoom levels (over 5x).

The rapeseed oil is a promising eco-friendly lubricant for applications involving environment protection. But any vegetal oil has shortcuts especially related to low viscosity and thermal stability. Research in additivation with nanoparticles is of interest for improving load capability of the contact and for reducing wear. Other tribological characteristics, as friction coefficient, could oscillate around values offered by the neat vegetal oil, with more or less influence of the system behavior. The four-ball tester offer a reliable ranking of the tribological characteristics when comparing two or more lubricants. Usually, researchers used test parameters recommended in ISO 20623:2017 Petroleum and related products. Determination of the extreme-pressure and anti-wear properties of lubricants. Four-ball method (European conditions) and ASTM D2596:2020 Standard Test Method for Measurement of Extreme-Pressure Properties of Lubricating Grease (Four-Ball Method), implying 1500 rpm for 1 hour for normal regime. This study proposes to evaluate the tribological characteristics (friction coefficient, wear scar diameter � WSD and temperature during the tests) for five sliding velocities and three loads, taking into account the same sliding distance for each test. The additives were at nano scale and they were supplied by the company PlasmaChem: hexagonal Boron nitride (h-BN) with a particle size of 100-1000 nm, mean value 500 � 100 nm, and nano graphene as foils, with a thickness of 1.4 nm and particle size up to 2 ?m. The additivated lubricants were obtained by sonication.

Published: April 2023

In the latest years, there was an interest in seeking for antimicrobial substances of botanical parts that have capability to suppress foodborne pathogens. Therefore, the antibacterial activity was evaluated on the crude juices produced from the mechanical pressing of some agro and food industrial byproducts, i.e., pomegranate leaves and peels and the leaves of fig, guava and olive. Also, the cytotoxicity effects of these crude juices on normal cells were estimated to check the safety of these crude juices on the human body. The results elucidate that the crude juice of pomegranate peels showed bactericidal ability against all tested bacteria. Olive leaves crude juice exhibited bactericidal ability against S. aureus, B. cereus and E. coli only, while guava leaves crude juice had a bactericidal activity against only S. aureus and P. aeruginosa. Otherwise, pomegranate leaves and fig leaves crude juices did not show any inhibition zones at all. Toxicological potential of crude juices under study revealed no cytotoxic effects at the concentrations used in the current study. Accordingly, pomegranate peels crude juice can be used as a naturalistic antibacterial substance to prohibit the deterioration of stored foods by bacteria moreover, the shelf-life of food would be expanded and massive economic losses due to food wastage would be avoided.

Published: April 2023

Surfactants as detergents and emulsifying agents are used in various fields of industry and agriculture. These amphiphilic compounds contain hydrophobic and hydrophilic fragments and are usually produced by large-scale chemical synthesis processes. However, recently there is a request to develop biotechnological methods to obtain surfactants, since biosurfactants have many advantages above their chemical analogues � higher tolerance to extreme temperatures, pH and salinity, higher stability and lower or zero negative environmental impact. Along with amphiphilic properties, surfactants produced by microorganisms may have additional properties such as inhibition of fungi or bacteria. The properties of biosurfactants are structure-dependent. Pseudomonas spp. are known to produce biosurfactants belonging to the rhamnolipids class. They consist of lipid tails and carbohydrate (mono- or dirhamnose) heads.
In the present study, biosurfactants produced by P. aeruginosa strain NCIM 5514 isolated from oil-contaminated soil were characterized. The product was evaluated by the Fourier transform infrared spectroscopy with the identification of functional groups (OH- for 3302 cm-1, -CH2 and -CH3 at region from 2929 to 2881 cm-1 and -C=O at 1735 cm-1) which are specific to this class, the emulsification index E24 at 200 ppm was to 90%. Thin layer chromatography with the following dying confirmed the chemical composition by the presence of rhamnose fragments and fatty acid residues. It has been shown that the biosurfactant produced by P. aeruginosa is highly effective in terms of surfactant properties in various cleaning approaches, and at the same time, able to inhibit the activity of the pathogenic fungus Fusarium oxysporum in the test for the suppression of radial growth of fungi at doses of 500 and 1000 ppm.

Published: April 2023

There is an emergent trend for the protection of geographical indication (GI) of medicinal plants, herbs and teas not only in the context of intellectual property rights, but also due to multiple concerns regarding contamination from polluted air, soil and water in some source countries, climate change, quality control and traceability. The mineral content coupled with chemometrics can be used to create elemental fingerprints. Lime flower (Tilia cordata), chamomile (Matricaria chamomilla), and Lady�s Bedstraw (Galium verum L.) of different provenience were used as plant material in this study. XRF spectrometry has been used for the determination of the mineral content of dry herbs. The results were compared with metal content values presented in different research papers and data bases and the elemental fingerprints of herbs were elaborated. Elemental fingerprints coupled with chemometrics can be used not only to evaluate the quality of herbs and teas, but also to authenticate the narrow-geographic origins of the plant material.

The paper presents an analysis of the impact of the enterprise on the state of the soil layer. The impact was considered as a complex of separate physical and physico-chemical processes. To do this, we used the method of determining the cleaning efficiency indicators developed by the author, which is based on a simulation experiment. The algorithm for conducting a simulation experiment on a set of models was used, taking into account the established coefficients, and 10,000 of its implementations were carried out. As a result of using the simulation experiment, the values that allow judging the quality of geofiltration have been determined. The risk of contaminant penetration into groundwater through the soil layer was analyzed based on the Harrington desirability scale. The obtained results that contain the dependence of the probability of complete cleaning of the pollutant with depth. During the passage of the filtration flow at a depth of 2.5 m, the maximum probability of complete purification for copper is reached, equal to ����=0.6086.

The aim of this paper was to evaluate the influence of some sweeteners adding on sensorial characteristics (appearance, consistency, colour, smell and taste), and some physico-chemical indicators (acidity, total soluble solids, total polyphenols content and antioxidant activity) of the chamomile soft drinks. The parameters were evaluated at 7 and 14 days respectively. These fermented soft drinks were obtained from chamomile flowers, bran, lemon juice and four types of sweeteners: white sugar, brown sugar, bee honey and Stevia rebaudiana dried leaves. The sensorial evaluation was by hedonic scale from 1-5 points. From sensory point of view, the version with bee honey was the best appreciated (average 4.42 points) by evaluators, followed by the one with brown sugar. Acidity was determined by titration with NaOH 0.1 n, the lowest value of acidity being recorded in the version with Stevia rebaudiana (7.5 ? 0.71 acidity degrees). The total soluble solids content was determined by the refractometric method, and the highest content was recorded in the version with white sugar (44.26 ? 3.65 Brix degrees). The antioxidant activity of the chamomile drink samples was evaluated using the CUPRAC spectrophotometric method, and the total polyphenols content was determined using the Folin-Ciocalteu method. The results of our study show that the best antioxidant activity (470.18 ? 0.8 mg Trolox/l) and the highest polyphenols contents (1.245? 2.57 ?mol gallic acid/ml) were registered in the variants with honey as sweeteners.

At one of the Kazakh uranium deposits, studies were carried out on the effect of ironoxidizing bacteria on the redox potential of leaching solutions. The studies carried out on three bioreactors with a volume of 1 m3 and one bioreactor with volume 6 m3 made it possible to establish a close relationship between the content of ferric iron in the solution and the redox potential of the leaching solution. In situ recovery of uranium uses sulfuric acid leaching solutions containing sulfuric acid from 3.5 g/liter to 25 grams/liter. Diagrams of the relationship between redox and the content of a trivalent iron in solution were obtained. This makes it possible to carry out an operational analysis of the composition of the leaching solution according to the redox of the solution directly in the conditions of the geotechnological field.

In the era of sustainable development, the sustainability-era, the different instruments, and modern tools to carry out actions and activities that lead to an increase in the quality of life, both rural and urban environment, led us to ask the following questions: What are in fact the visible or less visible costs, in the medium and long term, when we choose to carry out activities related to agriculture that have easy and short-term success? What are the risks or benefits of such activities, in the medium and long term? Also, the topic of the present article addresses a simple question: What type of agriculture is more convenient, better in the medium and long term?
Intensive agriculture with intense mechanization, which calls for intense chemicalization or organic agriculture, and the classic-traditional, green, more "rudimentary" one, if we look at it from the perspective of biotechnological discoveries, of the super-technological that takes place today in all fields of human activity?
We try to shed light on these aspects and analyze them in such a way that, thinking from the perspective of sustainable development and sustainability standards agreed by common agrarian development policies, we reach levels of quality of life that bring progress, satisfaction and well-being in all areas and at all levels of human development. The research methodology of our approach is based on the conclusions of statistical studies, INS, Eurostat, on the analysis of local and European agrarian development programs, on the documentation of scientific perspectives described in specialized papers, scientific articles on the topic we are dealing with.

Published: April 2023

The European Union and its Member States have set themselves to achieve climate neutrality across the EU by 2050. The agricultural sector is one of the emitters of greenhouse gases (GHG). To achieve its climate neutrality goals of reducing the increase in global temperature to below 2�C and limiting it to 1.5�C, the EU has adopted the Green Deal and the Farm to Fork Strategy based on it. These goals create the need for the development and implementation of innovations. The agricultural sector will experience several innovative approaches in the future, including the digitalization of agriculture and the use of biotechnologies, including microbiological approaches. As a result, the agricultural industry will face significant changes in farming methods. In this article, the need for innovation in agriculture, the main microbiological factors that determine both soil health and yield levels are discussed and the principle by which the economic benefits of using innovative microbiological preparations in agriculture are calculated is shown. The use of microbiological preparations in agriculture can maintain crop yields and reduce GHG emissions.

Published: April 2023

This paper presents the preliminary results obtained for the determination of some nutritional parameters of homemade chocolate fortified with nettle powder (NP) obtained from young nettle leaves grown in spontaneous flora, in pollution-free areas. 4 types of homemade chocolate with the addition of 2.5 � 10 % NP and a control chocolate (without the addition of NP) were prepared. Samples were analyzed from the proximate composition and mineral content point of view. The obtained preliminary results show that the chocolates fortified with nettle leaf powder contain important amounts of nutritional principles, which vary according to the percentage of NP added: 10.51 (chocolate with 2.5% NP) � 10.68% (chocolate with 10% NP) protein; 44.22 (chocolate with 10% NP) � 44.81 % (chocolate with 2.5% NP) carbohydrate; 20.30 (chocolate with 10% NP) � 22.05 % (chocolate with 2.5 % NP) fats; 2.87 (chocolate with 2.5% NP addition) � 3.66% (chocolate with 10% NP) minerals. In comparison with the control sample, chocolates with added NP contain higher amounts of minerals and slightly reduced fats. The concentration of essential microelements, determined in chocolates with the addition of NP, increases with the increase of NP percentage in the case of iron and manganese: 2.32-4.54 mg/100g Fe, respectively 0.42-0.79 mg/100g Mn and decreases slightly in the case of zinc: 2.15-2.20 mg/100g Zn. The copper concentration does not undergo obvious changes with the increase in the mass of added NP: 0.51-0.58 mg/100g Cu. Compared to the control chocolate (without the addition of NP), the chocolates with the addition of NP contain higher amounts of Fe and Mn; in the case of Zn and Cu, the differences are insignificant. Therefore, it can be stated that, compared to homemade chocolate, chocolates with added NP contain higher amounts of Fe and Mn and slightly lower amounts of Zn. Fortifying homemade chocolate with nettle leaf powder, in quantities that do not affect the aroma, flavor and taste (7.5%, in this experiment) can be a method of improving the nutritional qualities of homemade chocolate: it increases the mineral content, decreases the fat, and the carbohydrate contents do not undergo visible changes. In addition, thanks to the biologically active substances (polyphenols, flavonoids, etc.) contained in nettle powder, chocolates fortified with nettle powder have antioxidant properties closer to dark chocolate and a longer shelf life.

Published: April 2023

Aromatic plants have been one of the important concerns of man since the beginning of his existence. Seasoning plants, due to the presence in their composition of active principles with antibacterial and antifungal effect, allow a better preservation of food, a fact that over time has played an important role in preventing possible infections. Chlorophyll is the pigment that gives plants their green color and supports plants in absorbing energy and nutrients. Chlorophyll is found in most green plants and vegetables.
Chlorophyll can also benefit the health of the human body as it is a natural source of antioxidants.
Green chlorophyll pigments (chlorophyll a and b) and yellow pigments or carotenoide (carotenes and xanthophyll) represent photosynthetic or assimilatory pigments.
The purpose of this paper consisted in studies on the comparative content of chlorophylls, carotenes and xanthophyll in the fresh and dry leaves of 12 seasoning and aromatic plants from the Western region of Romania, namely: celery, dill, parsley, lovage, rosemary, thyme, mint, basil, tarragon, sorrel, sage and stevia. Concentration of chlorophylls, carotenes and xanthophyll was determined by a spectrophotometric assay.

If we refer to the sustainable development of a territory, it can be stated that the natural resources and implicitly the land resources, occupy the central place within this process, in this case, the land use can be seen as an "indicator" element of the trends of the process of sustainable development. The specialized literature shows, in various studies, the direct and indirect influence of the relief on the way of land use, implicitly on the distribution of grasslands, through altitude, slope or morphometric characteristics. In this context, the paper aims, in a holistic approach, to make an analysis of the distribution of grassland areas on altitudinal floors to quantify their share in relation to other categories of land use, depending on specific local factors (natural and anthropogenic). Two regions were selected that extend over an altitude range of approx. 1200 m, from 200 m, in the depression area, to 1340 m, in the mountain area, located in western Romania. The distribution of land use categories, respectively grassland areas, was analyzed in the GIS environment, based on Corine Land Cover data. The overlay analysis found that the grasslands are distributed on all defined altitudinal floors, in different environmental conditions, but their proportion is different, depending on local conditions. Differences were also found in the occupation of the space: in the low area, the grasslands are found on fragmented areas, interspersed with arable land and in the hilly and mountainous areas, the areas of grasslands are larger, compact, positioned at the edge of the forests.

Published: April 2023

Conventional wastewater treatment plants (CWWTPs) play a key role in reducing the environmental impact of urban wastewater. But nowadays, this role goes even further with climate change, water scarcity, and the current energy crisis. After the thickening of the secondary sludge, a wastewater flow is generated, which is normally recirculated to the plant head for further treatment. This work aims to use secondary thickener wastewater (STW) as a culture medium for Chlorella vulgaris, Neochloris oleoabundans and Scenedesmus quadricauda growth. These microalgae have the capacity to remove organic and inorganic matters, particularly, in wastewater rich in nitrogen and phosphate compounds. The experiments have been carried out in stirred photobioreactors with 1 L capacity under the following common operating conditions pH 8, mechanical agitation = 200 rpm, air supply rate = 0.5 L/min, continuous artificial illumination intensity = 359 ?E m-2 s-1, and non-sterilized conditions. The net biomass generated for C. vulgaris, N. oleoabundans, and S. quadricauda was 1.89 g/L, 2.73 g/L, and 2.52 g/L, respectively. The kinetic growth study showed a maximum specific growth rate, volumetric biomass productivity and culture duration for C. vulgaris (0.0128 h-1, 0.00583 g/(L h), and 429 h), for N. oleoabundans (0.0151 h-1, 0.00456 g/(L h), and 429 h), and for S. quadricauda (0.0146 h-1 and 0.007362 g/(L h), and 509 h). The microalgae biochemical composition determined biomass rich in energetic compounds (carbohydrates and lipids contents) between 70.9 % and 86.8 % with lower proteins and lipids contents between 9.17 % and 11.5 % and 6.29 % and 13.9 %, respectively. The final water quality registered lower chemical oxygen demand (COD) less than 157 mg O2/L. The final treated water can be direct discharge or used for irrigation.

Published: April 2023

In the frame of latest requirements to improve the renewable energy harvesting, the wind turbines get more and more used. Due to the propeller sizes, the blades� materials must comply with high resistance and weight requirements. As consequence, composite materials with dedicated structures are used. These materials are designed for long life and, as consequence, are potential pollution factors for the environment, after turbine working life is ended. Beside the methods to destroy the blades and give other use to the material, the optimization of the maintenance and repair procedures stand as valuable way to reduce both the turbines cost and the environment contamination. Taking into account the working conditions of blades such as the presence of the abrasive particles (sand or dust) and the high rotational speeds that can be reached, following the wind speed, the assessment of wear resistance of blades in abrasive conditions stands as valuable information for both designing and repairing procedures. In the present work, an industrial blade composite material is analyzed and subjected to abrasive wear with sand particles flowing in air stream, simulating the wind effect. A dedicated test rig is used, allowing to change the wear process parameters. After the abrasive tests, the damage evolution was observed by optical microscopy to identify the most affected areas of the blade, which provides important information for establishing of repairing procedures.

Authors: Pukite Vivita , Luksa Jolanta
Published: April 2023

The main document for the development of urban territories is the municipal territory development plan. When evaluating the aspects of territory planning and development, great importance are focused on the most beneficial land use as the main object of territory planning and greener development. The use of Latvia's natural capital are related to the sustainable use of land and natural resources, equally developing green production and green consumption, as well as simultaneously creating and maintaining the image of Latvia as a green country. The aim of the study is to evaluate the urban territory development planning in Latvia. The research uses the descriptive research method, so that, based on regulatory acts, scientific findings and real facts, the theoretical and regulatory aspects of urban territory planning are viewed. SWOT analysis and pair comparison methods are used for the evaluation of indicators. The results of the study show that the Jelgava municipality's achievements in promoting the city's development are a modern waste management system that promotes environmental sustainability. The study also revealed the negative aspects that hinder the development of urban areas, i.e. untidy or abandoned former industrial areas and untidy courtyards of apartment buildings. The study concluded that sustainable and balanced national development is the main issue in the development planning documents of urban territories in Latvia. In the direction of the green development of Latvia, it is necessary to work on the prevention of weak aspects, because they slow down the development of urban territories.
BIODIVERSITY, GEODIVERSITY AND CULTURAL DIVERSITY: THE NEXUS

Geographical areas with high biodiversity, high geodiversity and high cultural diversity tend to coincide. However, conservation strategies tend to consider these aspect of diversity separately, instead of considering them all together. Application of an integrated approach could potentially improve effectiveness of conservation actions and deliver significant benefits both to human and to the natural environment. Practical implementation of the integrated approach might, however, be problematic due to the fact that conservation actions have to consider different aspects of regional and global environmental change. In this context protecting isolated areas with high biodiversity, geodiversity and/or cultural diversity might not deliver desirable outcomes. Consequences of ongoing climate change deserve particular attention as it is not clear how flora and fauna could adapt to climate change in areas with currently low levels of geodiversity, and which consequences this might have for human society. Here we critically evaluate opportunities and limitations of an integrated approach to conservation of biodiversity, geodiversity and cultural diversity in the context of global environmental change, and consider potential applications of Nature-based Solutions to address this issue. Based on this critical analysis we propose practical and policy recommendations.
BUILDING ADAPTATION IN THE AGE OF CLIMATE CHANGE: HISTORICAL ASSET IN SANLIURFA TURKEY
Authors: Yildirim Mucahit
Published: April 2023

In the age of climate change, the sustainable adaptation of historical assets has gained importance. Adapting historical heritage assets helps to reduce energy consumption and environmental pollution. The sustainable adaptation of heritage assets causes minimal damage to natural and social environments by minimizing its use of these resources. The aim of using sustainability in conservation is to maximize the efficient use of an existing facility and minimize the negative impact on the environment. The physical features of cities change in response to climatic conditions. For example, population densities increase, tree coverage decreases, the temperature increases, and air humidity decreases. The climate proofing of historical assets addresses some impacts that are not reversible.
This study examines climate change through the sustainable adaptation of historical assets in Sanliurfa, which was chosen due to the diversity of its historical heritage and to its position as the hottest city of Turkiye where the greatest impact of climate change is overheating. A continental climate prevails in the region, and summers are long, hot and dry. The temperature differences between night and day and summer and winter are high. The study focused on adaptively reusing residential, commercial and institutional historical structures. The factors that damage the historical environment are temperature increases and precipitation changes in the city. Historical structures are extremely vulnerable in the age of climate change, and one of the solutions for their conservation is building adaptation.

Published: April 2023

Building Information Modeling (BIM) is a tool that increases information in the project. Within the effective management of construction projects, a view on economic sustainability is important. In the context of this, the BIM issue needs to be addressed within the limits of economic parameters and the impact on sustainability from this point of view. This research is focused on the analysis of BIM technology from the point of view of the economic sustainability of construction project management (CPM). The goal of the research is to analyze the possibilities and impacts of using BIM technology on the economic sustainability of construction projects and smart and safety in construction. The research is based on data from the construction industry, where BIM technology has been used. Construction in Slovakia has a long tradition. Research conducted on a sample of respondents and various participants in construction projects such as investors, developers, contractors, and designers. Various large companies are represented in the research, which proportionally try to reflect their representation on the market. The results of the research point to the need to use BIM technology and to the assumptions of the impact on the design of economic sustainability in the management of construction projects.
GREEN REAL ESTATE FOR SUSTAINABLE CITIES

In the last time there is an open dialog among scientists, economists, engineers, politicians, as well as city councils and municipalities, about future plans for urban development by considering green real estate for shaping sustainable cities. Applying the concept of sustainable development concretely means to develop and apply local strategies, not only in technology, and economy, but also in environmental and social fields, by considering sustainability requirements. In this regard it is obvious that mindset changes and behavior modifications, beside technological advance and environmental protection are foremostly required. For getting sustainable urban development several fields on a local level have to be simultaneously approached, in this regard green real estate requirements having main importance, several challenges being connected to this field when considering sustainability criteria. Taking this into account there is a need of changes in social field, i.e. changes in human behavior as well as mindset changes with regard to appropriate local infrastructure, environmental protection, as well as cultural life. The local level has to be at first considered for finding concrete strategies for urban sustainability in cadastral, energy, environmental, and social fields. The vision of shaping sustainable cities, by taking into account regional differences, is currently worldwide a pretty discussed topic, where cadastral aspects as well as green real estate design and valuation receives a pregnant role.
PROCEDURAL MODELLING OF BUILDINGS AND VISUALIZATION

Published: April 2023

Procedural techniques are used to generate 3D models, textures, images, and effects. Procedural modelling is widely used in areas such as architecture, archeology, and video games, and is based on a series of rules and algorithms. Computer-generated architecture (CGA) is a set of rules that software uses to automatically generate models. This paper describes the process of creating three models using CGA rules and procedural modelling. The models were created using the free Blender software and the geometry nodes system, which allows the user to procedurally modify geometry based on nodes. The process of modelling parts of the building, the materials, and the process of creating the procedural rules according to which the building models are generated are described in detail. An example of the building model was created, as well as two models based on real objects, the Westin hotel in Zagreb and the Mimara museum. In the end, the possibilities that procedural modelling provides in geodesy are described, such as spatial planning, simulation, facility management,

Authors: Sabo Jakub , Hromadka Vit
Published: April 2023

Investment projects aimed at brownfield revitalization have significant potential for the economic development of the area where they are located. Such a project usually removes old environmental burdens or deals with a problem with non-functional or dilapidated buildings. However, an appropriately set investment plan which respects internal territorial economic connections as well as the character of surrounding environment can provide solutions to other regional problems or implement economically beneficial activities both in the commercial and public sectors. Previous research identified and analysed in detail several brownfield revitalization case studies of various characteristics. The purpose of the presented paper is to synthesize the obtained information on the economic evaluation of individual brownfield types in order to determine a common platform for the evaluation of the economic efficiency of investment revitalization projects. The output of the paper presents a general overview of key input data for economic analysis including a proposal of its determination and evaluation resulting in a development of a key method for its implementation.
