The article analyzes the problem of dynamics and multidimensionality of landscapes on the example of landscape and technical systems. The object of the study is a landscape and technical systems, which are characterized by significant dynamics and multidimensionality of the structure. The basis for the publication of the article was the materials of long-term field observations conducted in the framework of research of the Vinnytsia school of anthropogenic landscape science under the direction of H. I. Denysyk. The authors’ contribution is to analyze the dynamics and multidimensionality of the structure and development of the valley-river landscape and technical systems of the Right Bank Ukraine, which lasted during 2007-2019. Knowledge of the dynamics of landscape and technical systems allows one to better understand the specifics of the transformation of the modern landscape sphere and to calculate possible negative trends. It is noted that the dynamics of landscape and technical systems are functional, spatial, and structural transformations, which are manifested in all components to the critical moment of transformation of a block system into a geocomponent one. Four types of dynamics are considered. Chronological dynamics characterize the spatial changes in the boundaries of the landscape and technical system. Structural dynamics involves a change in the morphological structure of the landscape and technical system and the relationships between its blocks. Temporal dynamics unites all changes in the landscape and technical system related to time. Directed dynamics presupposes stable, unilaterally directed transformations of the landscape and technical system with multiple changes of its state and structure. It is noted that each system has its own distinctive feature – multidimensionality, that is, the functioning within it of a number of separate and simultaneously interconnected paradynamic systems. The internal block system is limited by the landscape technosphere of the planet, which combines modern soils, man-made cover, and the air layer. The internal structural-morphological system considers the landscape and the technical system as a clearly defined gradation of taxa. The internal inter-block system provides interconnection in the landscape and technical system at the level of three blocks (managerial, natural and technical). The external complex system expresses the interaction of the landscape and technical system with other landscape complexes. Through the external air system, there is an entry into the landscape and technical system and the reverse radiation of solar radiation and interaction with remote landscape complexes due to the transfer of different types of air masses. In the underlying lithogenic system, the interaction of the landscape and technical system with the lithogenic base, which is represented by the earth’s crust and the upper mantle, is manifested. It is determined that the knowledge of the problems of dynamics and multidimensionality of landscape and technical systems becomes the central problem of engineering landscape science. The development of theoretical aspects of the functioning of landscape and technical systems is of great practical importance. Understanding the specifics of the structure and development of a particular landscape-technical system will increase its economic efficiency and minimize the negative impact on adjacent landscapes. Therefore, in the future, it is necessary to emphasize the research of modern geographers on the problems of multidimensionality and dynamics of different classes of anthropogenic landscapes.

Problem Statement and Purpose. Approaches, principles and methods of research of anthropogenic landscapes, in particular landscape-technical systems, are considered in detail in the works of many scientists. However, less attention is paid to the study of water management landscape technical systems. This necessitates more specific approaches, principles and methods that would allow to fully reveal the essence of these systems. Water management landscape-technical system is a complex system that combinesnatural, technical and information blocks that interact with each other. Therefore, researching these systems, in addition to traditional and specific, it is necessary to use at the integrated level the principles and methods of various natural sciences. Data & Methods. In the process of analysis and disclosure of approaches, principles and methods of research of water management landscape system, the following methods were used: structural and logical generalization (used to identify traditional methods in the study of the system), abstraction (selection of specific methods to reveal the essence of the system), system analysis (establishment of integration links between traditional and specific methods of scientific cognition), generalization (made it possible on the basis of the obtained data on methods of scientific cognition to develop a scheme for studying the water landscape system of the Trubizh river basin). Results. It is noted that the study of water management landscape technical system is impossible without the use of a systematic approach, which is traditional in all theoretical studies. Approaches that help to reveal the essence of the water management landscape and technical system (historical, basinal, system, paragenetic, constructive, cartographic and geoinformational) are identified and analyzed. The cartographic approach is singled out, which is one of the main ones in the study of water management landscape technical systems. There is a particular emphasis on the geoinformational approach, as the development of GIS projects is one of the most promising and modern trends in the study of not only water management landscape and technical systems, but also anthropogenic landscape science in general. The essence of specific principles and research methods is revealed, as they help to understand the peculiarities of the water management landscape and technical system. Three basic principles (historicism, natural anthropogenic compatibility and advanced study of previous natural and anthropogenic landscapes) were considered, on their basis seven methods of scientific research were identified and analyzed. The author emphasizes that, in addition to the main approaches, principles and methods, it is expedient to use methods from other sectoral sciences in the water management landscape and technical system study (geology, geomorphology, soil science, hydrology, zoology, botany etc.). A generalized study scheme of the water management landscape and technical system has been proposed, using the Trubizh River as an example.

Neva Bay

The macrophyte thicket ecosystems of higher aquatic vegetation in the Neva Bay (NB) and Eastern Gulf of Finland (EGoF) perform many important roles, including acting as the habitats, nesting sites and migration sites for aquatic and semi-aquatic birds, creating the specific conditions necessary for the spawning and growth of many species of fish, and taking part in the self-purification of the aquatic ecosystems. Many anthropogenic disturbances, hydraulic works in particular, have a significant negative impact on these macrophyte thicket ecosystems. In recent years, the active growth of a new type of macrophyte thicket has been observed in the NB. This is due to the aftereffects of the construction of the Saint Petersburg Flood Prevention Facility Complex (FPFC). It is quite likely that the total macrophyte thicket area in these waters is currently increasing. In the future, it will be necessary to assess the environmental impacts of the hydraulic works on the macrophyte thicket of the NB and EGoF, taking into account the background processes of the spatiotemporal dynamics of the reed beds in the waters in question. To do this, it will be necessary to carry out a comprehensive study of these ecosystems and identify patterns in their spatial and temporal dynamics. The program of the study has been developed and is currently being implemented by Eco-Express-Service, a St. Petersburg eco-design company.

Cheap does not imply cost-effective -- this is rule number one of zeitgeisty system design. The initial investment accounts only for a small portion of the lifecycle costs of a technical system. In fluid systems, about ninety percent of the total costs are caused by other factors like power consumption and maintenance. With modern optimization methods, it is already possible to plan an optimal technical system considering multiple objectives. In this paper, we focus on an often neglected contribution to the lifecycle costs: downtime costs due to spontaneous failures. Consequently, availability becomes an issue.

Statement of a problem. One of the main tasks today is to prevent accidents in complex systems, which requires determining their cause. In this regard, several theories and models of the causality of accidents are being developed. Traditional approaches to accident modeling are not sufficient for the analysis of accidents occurring in complex environments such as socio-technical systems, since an accident is not the result of individual component failure or human error. Therefore, we need more systematic methods for the investigation and modeling of accidents. Purpose. Conduct a comparative analysis of accident models in complex systems, identify the strengths and weaknesses of each of these models, and study the feasibility of their use in risk management in socio-technical systems. The paper analyzes the main approaches of accident modeling and their limitations in determining the cause-and-effect relationships and dynamics of modern complex systems. the methodologies to safety and accident models in sociotechnical systems based on systems theory are discussed. The complexity of sociotechnical systems requires new methodologies for modeling the development of emergency management. At the same time, it is necessary to take into account the socio-technical system as a whole and to focus on the simultaneous consideration of the social and technical aspects of the systems. When modeling accidents, it is necessary to take into account the social structures and processes of social interaction, the cultural environment, individual characteristics of a person, such as their abilities and motivation, as well as the engineering design and technical aspects of systems. Practical importance. Based on analyzing various techniques for modeling accidents, as well as studying the examples used in modeling several previous accidents and review the results of this modeling, it is concluded that it is necessary to improve the modeling techniques. The result was the appearance of hybrid models of risk management in socio-technical systems, which we will consider in detail in our next work.

The main disadvantages of the existing methods of managing the current state of technical systems are revealed. A non-standard approach is proposed for managing the functionality of the system in emergency situations. The character of the dynamics of the recovery processes of the technical system is determined as its state approaches the emergency one on the basis of the recommendations of the theory of self-organized criticality (SOC). The physical criteria for assessing the current state of the technical system are revealed. The rationale for using the physical indicator of the functional destabilization of the system is given. The signs of the pre-emergency state of the technical system are considered. A grapho-analytical model for the development of an emergency situation has been developed. The fact of the inevitable increase in the entropy of the system upon its transition to an emergency state is established. Structuring of the system development process in an emergency situation is carried out in three stages. The methodology for estimating the pre-emergency state of complex open systems is presented. The advantages of the proposed approach to managing the state of technical systems in comparison with traditional ones are established.

How do firms create and capture value in large technical systems? In this paper, I argue that the points of both value creation and value capture are the system’s bottlenecks. Bottlenecks arise first as important technical problems to be solved. Once the problem is solved, Then the solution in combination with organizational boundaries and property rights can be used to capture a stream of rents. The tools a firm can use to manage bottlenecks are, first, an understanding first of the technical architecture of the system; and, second, an understanding of the industry architecture in which the technical system is embedded. Although these tools involve disparate bodies of knowledge, they must be used in tandem to achieve maximum effect. Dynamic architectural capabilities provide managers with the ability to see a complex technical system in an abstract way and change the system’s structure to manage bottlenecks and modules in conjunction with the firm’s organizational boundaries and property rights.

Many times, in the attempt to win or to maintain an advantageous position on the market, the economic agent will use a whole arsenal of practices (inclusively and mostly from the marketing field), most of them anticompetitive, with a negative impact on the business environment, which also affects the well-being of the consumer. The policy in the field of competition is the one that defines these types of behaviour and penalizes them depending on the importance of their negative impact, by creating a complex and coherent legislative and institutional mechanism. The right enforcement of the competition policy at the national level is the key in this process, but this should be coordinated with the regional and international objectives and regulations in this field. Romania is facing a double challenge: on the one side, it had to set up a competition policy, which was almost ignored before the90s, on the other side, it had to comply, recently, with high standards in the field, as an EU candidate. Now, as a member state, the promotion of a competition culture becomes a must, along with the design of an adequate system of information and knowledge dissemination for all of those involved. The paper is based on a original and qualitative research and aims at emphasising the increased necessity of the promotion of a competition culture for the competitiveness of the Romanian business environment on the European level in the new context of accession. This will help Romanian business to face the competition challenges within a more extended single European market, as an essential issue of the free market economy status recently granted, and accordingly to the most important EU objectives set up at Lisabon to become the most competitive economy in the world up to 2010.

The development of religious extremism in Indonesia continues to increase every year so that serious attention is needed by the government to deal with religious extremism in Indonesia. Indonesia is an archipelagic country where there are various ethnic groups and religions that coexist. However, the development of religious extremism sometimes becomes a serious problem for the Indonesian people because it can have a negative impact and damage the unity between nations and religions. This research uses literature study. This research method is carried out by reviewing various literatures, both books, newspapers, survey reports, academic journals related to religious extremism in Indonesia. The results show that not all religious extremism has an impact on the emergence of terrorism, but the government still must make the right policies in handling religious extremism that can cause division and affect peoples welfare. The policies that have been made by the government are considered appropriate and based on the laws that have been set by the government so that they can have a positive impact in maintaining the unity and integrity of the Indonesian nation.
