Due to the planned exploitation of the Gubin lignite deposit by opencast method, a numerical hydrogeological model was built. The main goal of the model was to forecast the development of the cone of depression caused by the future mine dewatering. Due to the location of the mine near the Nysa Łużycka River, a drainage system will be developed. The main task of this system is to eliminate the development of the cone of depression in the upper Quaternary aquifer in Germany, as well as to protect the Natura 2000 areas located in the immediate vicinity of the mine against harmful effects on groundwater-dependent ecosystems. The modelling studies allowed analyzing the efficiency of slurry walls, deep barriers of recharge wells, and shallow soakaway systems for water from the future mine dewatering. It has been shown that in case of dewatering of a multi-layer aquifer complex with many hydraulic contacts, the use of slurry walls may be insufficient to limit the development of the cone of depression. However, the combination of slurry walls with the systems recharging the aquifers enables effective counteracting the negative impact of dewatering on the environment.

The combined mining under the condition of underground mining in the aquifer rock mass of the open-pit sides raises an acute issue of joint drill-and-blast works (D&B). The construction of an underground mine begins normally with the approach of the open-pit mine depth to the final marks. In this situation, if there is a volume for the cutback, it is very small, and the blast works come close to the limit open-pit contour, behind which the protected rock mass is located and in the future the underground mining is supposed to be carried out. The main task in the drill-and-blast works under such conditions is to preserve the stability of this rock mass. The well-timed shielding of the blast and creating the fracture surfaces by the trim blasting reduce the negative impact of the blast on the open-pit side, but do not always prevent the propagation of stress waves caused by the seismic effect along the rock mass. Therefore, restriction of the seismic effect of blast in the border zone is as important for the stability of the rock mass as professional deviated contour holes.

The primary goal of this paper is to suggest potential methods of post-mining areas management. Moreover, such methods must be compliant with the expectations of the residents of a given area. The assessment of natural and socio-economic factors affecting the choice of optimum reclamation and revitalization approaches was carried out using the following research methods: analysis of the available literature, case study, field research, photographic documentation. An analysis of the impact of deposit exploitation of mineral aggregates on protected species and their habitats located within the Natura 2000 sites was done. The scale of the problem is enormous. A proper approach needs to be developed among the economy, society and organization of managing the network. The Natura 2000 network covers huge areas simultaneously utilized for other purposes than nature conservation. The Natura 2000 network is in serious conflict with industry, especially with open-pit mining due to the location of mineral deposits. The results can be used to resolve conflict situations on Natura 2000 sites. An undertaking will only receive a go-ahead if it exerts no negative impact on a given area and if the public approves of it. Plans and undertakings having a negative impact on a given area are authorized but on the condition that mitigating measures are taken.

The purpose and tasks of the work are to analyze the contemporary Ukrainian mass culture in terms of its value and humanistic components, as well as the importance of cultural studies and Ukrainian studies in educational disciplines for the formation of a holistic worldview of modern youth.Analysis of research and publications. Scientists repeatedly turned to the problems of the role of spirituality in the formation of society and its culture. This problem is highlighted in the publications by O. Losev, V. Lytvyn, D. Likhachev, S. Avierintsev, M. Zakovych, I. Stepanenko and E. Kostyshyn.Experts see the main negative impact of mass culture on the quality approach, which determines mass culture through the market, because mass culture, from our point of view, is everything that is sold and used in mass demand.One of the most interesting studies on this issue was the work by the representatives of Frankfurt School M. Horkheimer and T. Adorno «Dialectics of Enlightenment» (1947), devoted to a detailed analysis of mass culture. Propaganda at all socio-cultural levels in the form is similar in both totalitarian and democratic countries. It is connected, according to the authors, with the direction of European enlightenment. The tendency to unify people is a manifestation of the influence of mass culture, from cinema to pop. Mass culture is a phenomenon whose existence is associated with commerce (accumulation in any form – this is the main feature of education), in general, the fact that it exists in this form is related to the direction of the history of civilization.Modern mass culture, with its externally attractive and easily assimilated ideas and symbols, appealing to the trends of modern fashion, becomes a standard of prestigious consumption, does not require intense reflection, allows you to relax, distract, not teach, but entertains, preaches hedonism as the main spiritual value. And as a consequence, there are socio-cultural risks: an active rejection of other people, which leads to the formation of indifference; cruelty as a character trait; increase of violent and mercenary crime; increase in the number of alcohol and drug addicts; anti-patriotism; indifference to the values of the family and as a result of social orphanhood and prostitution.Conclusions, perspectives of research. Thus, we can conclude that modern Ukrainian education is predominantly formed by the values of mass culture. Namely, according to the «Dialectic» by Horkheimer and Adorno, «semi-enlightenment becomes an objective spirit» of our modern society.It is concluded that only high-quality education can create the opposite of the onset of mass culture and the destruction of spirituality in our society. It is proved that only by realizing the importance of cultivating disciplines in the educational process and the spiritual upbringing of the nation, through educational reforms, humanitarian knowledge will gradually return to student audiences.Formation of youth occurs under the influence of social environment, culture, education and self-education. The optimal combination of these factors determines both the process of socialization itself and how successful it will be. In this context, one can see the leading role of education and upbringing. It turns out that the main task of modern education is to spread its influence on the development of spiritual culture of the individual, which eventually becomes a solid foundation for the formation of the individual. Such a subject requires both philosophical and humanitarian approaches in further integrated interdisciplinary research, since the availability of such research will provide the theoretical foundation for truly modern educational and personal development.

Subject. The article considers financial regulation through the use of tax mechanisms. Objectives. The aim of the study is to evaluate European and Ukrainian practices of fiscal incentives for farming through fiscal instruments with VAT playing the key role. Methods. In the study we employed economic and statistical research methods, like monographic, comparison, scientific generalization. Results. Based on the analysis of VAT implementation on farmers in developed countries in Europe we substantiated the conclusion about its focus on simplifying the tax procedures and eliminating the negative impact on operations of economic entities. Special tax treatment (including VAT collection) is mainly used to streamline tax relations, taking into account the specifics of farming, rather than to improve the financial support to farms. We revealed that in the Ukrainian practice its main task is financial support to agricultural production. Conclusions and Relevance. The experience of developed European countries on the use of special tax regimes and taxation procedures should serve as a model for Ukraine. Financial incentives for agricultural production development should be directly supported by the State, and special tax treatment and tax administration should be focused on streamlining tax relations in the region, based on the practice of developed European countries such as UK, Germany, Italy and France.

The present national Air Traffic Control system is a ground-centralized, man intensive system which through design allows relatively little meaningful pilot participation in decision making. The negative impact of this existing design can be measured in delays, dollars and lives. The FAA's design plans for the future ATC system will result in an even more intensive ground-centralized system with even further reduction of pilot decision making participation. In addition, controllers will also be removed from on-line decision making through anticipated automation of some or all of this critical function. Recent congressional hearings indicate that neither pilots nor controllers are happy or sanguine regarding the FAA's design for the future ATC system.

In 1980 work began on one of the most intensive and comprehensive marine research and development projects—the German Ship of the Future. The main task was the reduction of the operational costs of a vessel. After five years of work the project was successfully finished with the maiden voyage of the first SdZ prototype ship. The paper describes first the R&D project itself. The organizational structure, the financial background and some examples of development topics are explained. The second part deals with the conversion of the outcomes of the R&D project into the reality of a containership. The third part gives, by example of some focal points of the newly developed ship service technique, a broad description of the HDW-SdZ prototype ships and their economy. A short outlook to further developments concludes the paper.

This study investigates how the development of artificial intelligence (AI) is perceived by the students enrolled in technical and humanistic specializations at two universities in Timisoara. It has an emphasis on identifying their attitudes towards the phenomenon, on the connotations associated with it, and on the possible impact of artificial intelligence on certain areas of the social life. Moreover, the present study reveals the students’ perceptions on the sustainability of these changes and developments, and therefore aims to reduce the possible negative impact on consumers, and at anticipate the changes that AI will produce in the future. In order to collect the data, the authors have used a quantitative research method. A questionnaire-based sociological survey was completed by 928 students, with a representation error of only ±3%. The analysis has shown that a great number of respondents have a positive attitude towards the emergence of AI, who believe it will influence society for the better. The results have also underscored underlying differences based on the respondents’ type of specialization (humanistic or technical), and their gender.

<p>Positive communication is communication that is able to develop its positive potency of children. Positive communication is built to form the fabric of a child’s personality that will also be established between parents and children. It can cultivate emotional intelligence. Of course, these two things will make a valuable provision for children’s development in the future. While missed communication would cause them uneducated and ignorant. Failure in communicating would<br />normally make a child called weird or crazy. Actually there are a few tips to succeed in realizing the potency of the child’s qualified personality, such as provide exemplary son, make the house as a science park, provides a vehicle for creativity, avoid negative emotions and always pray for children to be always given a good personality and mental health. Later in the development potency of the child’s personality can also be affected by a variety of factors. One of them is the positive communication patterns of parents towards their children (get them to always communicate in a positive environment). If the communication patterns of parents are bad, the negative impact will be felt by the child as well.</p>

The aim of this study is to realize an analysis of public-private partnerships (PPPs) in Albania. Our focus will mainly be the PPPs in the energy sector. Public-private partnerships contracts have experienced a significant increase in the last decades in Albania. They have had a great impact on public finances of the country, this is why they have often been “attacked” for the negative impact that they might have on the actual and especially the future of the country. We will work to make a comparative analysis of the cost and benefits that Albania has had from signing these contracts. We will also work to analyze the management of these public-private partnerships during the pandemics, which will be helpful to reveal the possible difficulties that the government might have in managing them. Something that has inspired us to make a deeper analysis of them is related to the energy crises that the country has experienced in the last years. We want to “dig” deeper in order to see if these PPPs are really worth it or not. Is it worth or it brings a burden for the actual and future generations of Albania?
