Creation of close-to-nature river beds is one of the results of watercourses revitalization. Watercourses are segments in the country increasing its recreational potential.The recreational potential of watercourses contributes to rich diversity of animal and plant species. They are well-preserved natural environment with a different atmosphere and an interesting psychological effect. The current goal of revitalization measures in the landscape primarily consists of the optimization of landscape water regime, incl. flood control measures and the promotion of biodiversity, but the current philosophy speaks of multifunctional land usage. However, the revitalization is currently underappreciated in the Czech Republic and it is important to increase the recreational potential of the landscape. The subject of this article is evaluation of close to nature watercources from the point of view of recreation potential. The example locality of close to nature watercourse is part of Váh river near Iľava city. In this area some elements of recreational potential by the proposed methodology are discussed. Two river courses make a possible comparison between a technical canal and a modified one, but close-to-nature water course with all parameters of river phenomenon. Properties of nature and close-to-nature watercourses could be an inspiration for repairing(modifying, adjusting) river stretches within urban space.

Water coursess are segments in the country increasing its recreational potential. The current goal of revitalization measures in the landscape primarily consists of the optimization of landscape water regime, incl. flood control measures and the promotion of biodiversity, but the current philosophy speaks of multifunctional land usage. In the society there has been indicated the necessity for recreation, because a large part of the population lives in urban settlements and is employed in an artificial technical environment that has largely inadequate sanitary conditions (unfavourable microclimate, noise, dust, etc.). Recreation as a social phenomenon is therefore a permanent part of the lifestyle in economically developed countries. However, the revitalization is currently underappreciated in the Czech Republic and it is important to increase recreational potential of the landscape. The subject of this article is evaluation of regulated watercourse Ostravice river in Ostrava urban area. The model area of river Ostravice in Ostrava region is described here. In the model area is evaluated some elements of recreational potential of revitalization by the proposed methodology. The outcome of the work is to propose an ongoing systematic procedure for assessment of the relevance of revitalization actions in terms of the recreational potential of the landscape and their impact on the development opportunities of the region.

Catchment Areas

A short introduction of historical overview and current situation refer to forestry problems of the country. Local climate is characterized and impacts of natural phenomena are described, as well as the impacts of human beings. The influence of forest management is mentioned and discussed in relation to latest catastrophic floods. The territory of the Czech Republic is damaged especially by a high intensity of atmospheric precipitation abnormal values which lead to a local or regional damage. In the catchment areas of torrents, damage leads to faster soil erosion, development of ravines, landslides, moving of soil sediments and their deposition, devastation of watercourse beds and properties, flooding while the flooding rates of flow represent a danger for the life of inhabitants. Important elements and results of respective research are described in brief. E.g. research of precipitation and its relation to the runoffs in the small mountain catchment areas with the forest stands restoration, as well as the forestry-hydrologic monitoring of forest environment, which has been taking place since 1928, and tradition of the service for torrent control. Forestry-hydrologic research gradually documents that a favorable flood-control performance of forest is limited. However, this is not a reason for not taking care of flood-control measures in the mountain afforested areas. These measures and importance of forest for the protection of land are historically verified and justified. In closing the mankind behavior to the landscape is underlined as a question mark.

There are 30 Conservation Authorities in Ontario with a total area of 20,000 square miles. They have been established to co-ordinate all conservation work including flood control, land use, reforestation, fish and wildlife management and recreation on a watershed basis.The Conservation Authorities are bodies corporate composed of representatives from all the municipalities lying wholly or partly in the watershed. They may obtain grants from the Province of Ontario and, in some cases, from the Government of Canada.The Grand Valley Conservation Authority, which has jurisdiction over a watershed of 2,600 square miles in the agricultural region of Ontario, has been used as an example. About 10 per cent of this watershed remains in woodland composed of headwater swamps and farm woodlots, and for this reason the subject has been dealt with from the point of view of hydrometeorology rather than from the point of view of forestry.

The study reviews scientific literature concerning the cities of the Tobolsk province in the late XVIII – early XX centuries. The article  features the works of scientists, published in the pre-revolutionary  period and affecting different sides of the subject in question. The  results of the research indicate that before 1917 the scientific works  were mainly concentrated on such aspects of urban life as  demography, trade, administration, urban space, education, local  government, and periodicals. The authors did not distinguish the  concept of «social life» as a separate phenomenon, limiting the  study of its individual components. The methodology includes the  use of techniques and tools of local, systemic, comparative- historical, and problem-chronological methods, as well as  developments «history of everyday life» and «new Imperial history». In general, the article emphasizes the expansion of scientific  knowledge about the social history of Siberian cities in the post- reform and late Imperial periods, reveals the influence of the  researchers ' views on the integration of urban life. The scope of the  study is not limited to the interest of historians, urbanists and local  historians to the subject of study. Historiographical analysis is  relevant from the point of view of modern discussions about the  prospects of urban studies, and can also be used in the preparation  of textbooks and summaries on Siberian history.

The City

The study tested that cities are studied from different perspectives: from city-to-city links, structural elements of urban space to everyday practices of cities. Among the representatives of the scientific field, which made a significant contribution to the development of the theory of urban research is to highlight J. Bodriyar, P. Bourdieu, D. Becker, D. Jacobs, C. Lynch, A. Lefevra, M. Castells, D. Garvey, A. Scott, R. Pal, J. Fischer, H. Delitz and others. Moreover interesting and thorough are the scientific works of Ukrainian researchers – V. Sereda, M. Sobolevskaya, L. Males, Y. Soroka, D. Sudin, A. Petrenko-Lisak, A. Mikheeva, L. Nagorna, O. Musiyuzdov and a number of others. In this case, the methodological position of the researchers is relevant, which states that the symbolic space of the city is formed through the ability of visual objects to translate cultural and symbolic codes with the help of geometric, semantic and aesthetic characteristics. For example, in this work, one of the key terms is «architectural landscapes» with which it is possible to analyze the combination of spatial forms in the city with meaningful cultural and ideological content. It was recorded that the signs or symbolic markers can serve as architectural buildings, monuments, memorable signs, street names, informational and promotional posters, and so on. The main objects of research in the sociology of the study of architectural forms gradually became the phenomenon of buildings and structures, as well as the development of theoretical directions in architecture, the study of the place and role of space in sociology and cultural studies. As a result in the methodological space, along with the phenomenological, anthropological, and linguistic turns, the term «architectural turn» appears. From the point of view of the system theory, architecture is not seen as the main subject of research, namely communication on architecture. Accordingly, institutional theory in sociology considers architecture as an «institutional mechanism» that firmly asks individuals a certain social order and allows for the implementation of architectural ideas. On the other hand, at the same time, open questions remain regarding the meaningful content of the meanings contained in the objects of architecture. The postmodern direction, which reveals other aspects of the study of architectural forms, deserves special attention. Discreteness Architectural of social life, «decentralization of the subject», the decomposition of reality into actual and virtual, freedom and spontaneity as characteristics of the postmodern era are reflected and read in the architecture of postmodern. The architectural space of the city is considered by a number of domestic and foreign researchers in the context of symbolic interaction between power structures and actors through architectural constructions and design of a living environment.

Polders show an important water-management function in the flood-control protection of watersheds. The course of actual floods in recent decades and effects of the water works on flood flows have proved the suitability of the construction within integrated flood-control measures in particular watersheds of the Czech Republic. To determine the transformation effect of flood-control measures in watersheds mathematical modelling is an important method, which is used not only in the preparation and design of retention areas but also in dealing with the flood protection of towns and villages. Easy verification of other measures in watersheds is also useful. Their implementation can be thus prepared for the future or it is possible to back off the intentions. In our case, a fact is advantageous that the model is ope­ra­ted in the workplace of the Elbe Basin water-management dispatching centre, which is compatible with assessed polders in the partial Elbe watershed, namely in the Tichá Orlice watershed and its partial Třebovka watershed. The polders assessed are situated on the Třebovka stream, which is the lar­gest tributary of the Tichá Orlice river. These dry reservoirs and the increased protective function of the Hvězda pond affect runoff from about 80 km2. Within research activities, possibilities were studied to obtain necessary retention areas in existing small water reservoirs. It became evident that the only rea­lis­tic solution was to increase protective functions of the pond Hvězda. Its present total retention space of 1.4 million m3 can be increased only by 0.35 million m3, however, in combination with the sophisticated lay-out of a new emergency spillway and outlet the whole retention space can be used much more effectively. To obtain other retention areas localities were found out in the whole upper watershed of the Třebovka stream, which fulfilled requirements for placing the adequate capacity of polders. Subsequent modifications of the Třebovka channel in the most endangered villages and towns and their capacity design according to transformation effects of selected reservoirs and measures, determination of their effect and comparison with profiles on the Tichá Orlice are the content of the paper.

The Neural Network

In the context of this article, a method for detecting threats based on their forecasting and development in complex distributed systems is proposed. Initially, the relevance of the research topic is substantiated from the point of view of the prospective use of various methods in the framework of threat management and their forecasting in complex distributed systems. Based on the analysis of these methods, a proprietary forecasting method based on the second generation recurrent neural network (RNN) was proposed. The mathematical formulation of the problem is presented, as well as the structure of this neural network and its mathematical model of self-learning, which allows achieving more accurate (with less error) results in the framework of threat prediction (in this case, the level of water rise at gauging stations) in complex distributed systems. An analysis was also made of the effectiveness of the existing and proposed forecasting methods, which showed the stability of the neural network in relation to other forecasting methods: the error of the neural network is 3-20% of actual (real) water levels; the least squares method reaches up to 34.5%, the numerical method in a generalized form - up to 36%; linear regression model – up to 47.5%. Thus, the neural network allows a fairly stable forecast of the flood situation over several days, which allows special services to carry out flood control measures.

SummaryIn the Marinelli chair, a geometry widely used in whole body counting, the lower part of the leg is seen quite inefficiently by the detector. The present paper describes an attempt to modify the standard chair geometry to minimise this limitation. The subject sits crossed-legged in the “Buddha Posture” in the standard chair. Studies with humanoid phantoms and a volunteer sitting in the Buddha posture show that this modification brings marked improvement over the Marinelli chair both from the point of view of sensitivity and uniformity of spatial response.

Narrative Perspective

Summary This article examines the urban themes in Leo Lipski’s micro-novel Piotruś: An ApocryphalTale from 1960. The narrative relies on both traditional realism (for the most part) and the 20thcentury subjective point-of-view technique to represent urban space, which in this case belongs to be a well-defined geographical location. The use of personalized narrative perspective turns the urban space of Tel Aviv-Jafa - heterogeneous and subject to differing assessments - into a labyrinth, closed, dense, expanding horizontally, chthonic, and alien.

To implement any successful policy, research about the subject-matter is essential. Lack of knowledge would result in failure and, from an economic point of view, it would lead to a waste of scarce resources. The book under review is essentially a manual which highlights the use of research for development. The book is divided into two parts. Part One informs the reader about concepts and some theory, and Part Two deals with the issue of undertaking research for development. Both parts have 11 chapters each. Chapter 1 asks the basic question: Is research important in development work? The answer is that it is. Research has many dimensions: from the basic asking of questions to the more sophisticated broad-based analysis of policy issues. The chapter, in short, stresses the usefulness of research which development workers ignore at their own peril.
