The regenerative potential of a city as an ever- changing complex system is revealed by the evaluation results of the potentials of its subsystems. To reach this aim, method of fractal analysis can be used, which not only reveals the form properties of an evaluated structure but its functionality as well. The urban potential is understood as meta-functional possibilities of city territories, which are determined by fractal indexes of structures (as generators of streams), streets (as connections between generators), greenery (as eco-compensational territories and green generators of streams in bipolar system of meta-functional zones of a city) and public spaces (as generators of streams and spaces of communications). Using this method, evaluation of potential of Kaunas urban structures was performed. The results of the analysis allowed identifying meta-functional zones of Kaunas city: urban frame, nature frame and background areas with unused potential of urban qualitative and quantitative development, indicating the weak sides of their urban morphological structure. The results also allowed identifying complex parameters of a spatial code of valuable urban areas that can be applied regulating use of the territories. Santrauka Miesto, kaip nuolat besikeičiančios sudėtingos sistemos, atsinaujinimo ir evoliucionavimo potencialą atskleidžia apibendrinti jo posistemių potencialų įvertinimo rezultatai. Tam tikslui gali būti naudojamas fraktalinės analizės metodas, kuris atskleidžia ne tik vertinamos struktūros formos savybes, bet ir jos funkcines galimybes. Urbanistinis potencialas suprantamas kaip metafunkcinės miesto teritorijų ir erdvinių struktūrų galimybės, kurias parodo pastatų (srautų generatoriai), gatvių (ryšiai tarp generatorių), želdynų (ekokompensacinės teritorijos ir žalieji srautų generatoriai miesto bipolėje metafunkcinių zonų sistemoje) ir viešųjų erdvių (srautų generatoriai ir ryšių erdvės) fraktaliniai indeksai. Naudojant šį metodą atliktas Kauno urbanistinių struktūrų potencialo vertinimas. Tyrimo rezultatai leidžia išryškinti metafunkcines Kauno miesto zonas: urbanistinį karkasą, gamtinį karkasą ir fonines, neišnaudotų urbanistinės kokybinės ir kiekybinės plėtros galimybių teritorijas, nurodant jų urbanistinės morfostruktūros trūkumus. Rezultatai taip pat leidžia identifikuoti vertingų urbanistinių teritorijų erdvinio kodo kompleksiškus parametrus, kurie gali būti naudojami reglamentuojant teritorijų panaudojimą.

The Relationship

Nautical tourism ports make an open, dynamic and complex system which has been rapidly evolving; this is the reason why the development of this system requires continual monitoring and research. The existing models and development plans concerning nautical tourism ports donot provide for a systematic qualitative and quantitative development of nautical tourism, thus contributing to economical inefficiency likely to cause even ecological imbalance. The more so if nautical ports are regarded as business subjects by whom the concept of sustainable development is declaratively acceptable. For this reason, this paper presents in a systematic and clear way the results of the research based on an overall analysis and evaluation of nautical tourism ports’ position and development plans. On the basis of the results obtained, the paper presents a model of sustainable development of nautical tourism ports whereby the authors propose to redefine the approach to planning the development of nautical tourism and particularly to creating the offer and to understanding the relationship between economic development and environmental protection.

The Status

Urban poverty is one of multidimensional issue in Nepal. Increasing immigration from the outer parts of Kathmandu due to rural poverty, unemployment and weak security of the lives and the properties are core causes pushing people into urban areas. In this context how squatter urban area people sustain their livelihoods is major concern. The objectives of the study are to find out livelihood assets and capacities squatters coping with their livelihood vulnerability in adverse situation. Both qualitative and quantitative methods are applied for data collection. It is found that squatters social security is weak, victimized by severe health problems earning is not regular with lack of physical facilities and overall livelihood is critical. This study helps to understand what the changes that have occurred in livelihood patterns and how poor people survive in urban area.

Abstract The Poblenou Superblock, in Barcelona, is a crucial element in the development of the new city-planning within the framework of the Superblock (Superilles) concept, whose principal aim is to recover the cultural, economic and social exchanges once produced in streets and squares. People living in urban areas need a lower traffic density, more green spaces and cleaner air in order to restore the previous uses of public spaces in their day-today lives. The urban actions conducted at this Superblock to change its uses were completed about 3 years ago, and neighbours and workers have already taken over the new spaces. In an interdisciplinary work on urban planning and acoustics, we detail the preliminary results of the acoustic events found in the recordings in a soundwalk in the heart of the Poblenou Superblock. Fifteen people evaluate and record sound fragments with the Hush City App application, in order to establish comparisons between the different points of the route, observe the spaces arranged for people and perceive the soundscape. Meanwhile, several acoustic technicians record 5-min long audios in the different stops designed for the soundwalk. The points chosen to make the recordings are very different from each other, some of them in the middle of gardens and others are on pacific streets and finally, we also wanted to include Superblock borders where the traffic is still very present. The results of our study were promising and have encouraged us to further investigate acoustics events in superblocks and include all the perceptual information provided by the Hush City App.

The Impact

Future sea-level rises on the urban waterfront of coastal and riverbanks cities will not be uniform. The impact of floods is exacerbated by population density in nearshore urban areas, and combined with land conversion and urbanization, the vulnerability of coastal towns and public spaces in particular is significantly increased. The empirical analysis of a selected number of waterfront projects, namely the winners of the Mies Van Der Rohe Prize, highlighted the different morphological characteristics of public spaces, in relation to the approximation to the water body: near the shoreline, in and on water. The critical reading of selected architectures related to water is open to multiple insights, allowing to shift the design attention from the building to the public space on the waterfronts. The survey makes it possible to delineate contemporary features and lay the framework for urban development in coastal or riverside areas.

Public spaces are designed and managed in many different ways. In Hanoi, after the Doi moi policy in 1986, the transfer of the public spaces creation at the neighborhood-level to the private sector has prospered na-ture of public and added a large amount of public space for the city, directly impacting on citizen's daily life, creating a new trend, new concept of public spaces. This article looks forward to understanding the public spaces-making and operating in KDTMs (Khu Do Thi Moi - new urban areas) in Hanoi to answer the question of whether ‘socialization’/privatization of these public spaces will put an end to the urban public or the new means of public-making trend. Based on the comparison and literature review of studies in the world on public spaces privatization with domestic studies to see the differences in the Vietnamese context leading to differences in definitions and roles and the concept of public spaces in KDTMs of Hanoi. Through adducing and analyzing practical cases, the article also mentions the trends, the issues, the ways and the technologies of public-making and public-spaces-making in KDTMs of Hanoi. Win/loss and the relationship of the three most important influential actors in this process (municipality, KDTM owners, inhabitants/citizens) is also considered to reconceptualize the public spaces of KDTMs in Hanoi.

The Individual

The characteristics of the hazard of urban soils pollution by polycyclic aromatic hydrocarbons (PAHs) are considered: naphthalene (Naph), anthracene (An), phenanthrene (Phen), pyrene (Py), fluoranthene (Flu), chrysene (Chr), benzo(a)anthracene (BaA), benzo[a]pyrene (BaP), benzo[b]fluoranthene (BbFlu), benzo[k]fluoranthene (BkFlu), dibenzo[ah]antracene (DBa), benzo[ghi]perylene (Bghi), indeno[1,2,3-c,d]pyrene). On the example of monitoring data on the RUDN University campus and the adjacent South-West Forest Park, modern approaches to assessing the hazard of pollution levels and the environmental risk of soil pollution are demonstrated: RQ indicators, total relative toxicity in comparison to BaP, carcinogenic risk, behavior of the representative PAHs. On the basis of a critical analysis of the pollution indicators, the optimal approaches to assessing the danger of the presence of polyarenes in the soils of urban areas are demonstrated. The leading sources of pollution (influence of vehicles) were identified. Different levels of environmental hazard of polyarene soil contamination in different functional zones of the analyzed territory are demonstrated: relatively clear territory in the middle zone of the park and a specific configuration of the pollution field on the rest of the territory. The necessity of developing ecosystem standards for urban natural complexes is justified, taking into account the individual characteristics of soils, the role of soil microbiota, the specificity of the use of the territory and the characteristics of pollution sources.

The vegetation of the Samara Region is characterized by a relatively high content of copper. This biogeochemical feature is typical for natural and technogenic transformed ecosystems of the region. Copper is included in the group of elements of the 2nd hazard class. At certain concentrations it is necessary for the normal functioning of all organisms, but with increasing concentrations in the environment or in food it shows toxicity. The technogenic sources of copper include metalworking and machine-building enterprises, fertilizers, road and rail transport, wastewater, products of incomplete fuel combustion and refining characteristic of the Samara Region. The peculiarities of copper accumulation and distribution in soils of urban areas of the region are insufficiently studied. Previously, such studies were carried out only in certain areas of Samara. The paper analyzes in detail the level of technogenic copper pollution of the soil cover in Novokuybyshevsk. Ecological and geochemical studies in Novokuybyshevsk were carried out for 3 years (2016-2018) on 7 stationary test plots in its different functional areas and on 1 background test plot. The objects of research were soil samples taken from the upper humus horizon (layer 0-10 cm). The quantitative content of copper in soil samples was determined by the method of inversion voltammetry. A comparative analysis revealed territories of Novokuybyshevsk with relatively high, medium and low levels of copper in the soil. The first group included the Park Dubki in its elevated part, the old residential area on Kirov Street, the roadside area at the intersection of Pobeda Avenue and Dzerzhinsky Street (93,3-90,7 mg/kg). The second group with an average copper content (71,0-73,3 mg/kg) included the square Elochki and a new residential area on Ostrovsky Street. The third group with a relatively low copper content (38,3-54,7 mg/kg) included three sample areas: the lowland part of the Park Dubki, the industrial zone and the background area. The concentration of copper in the soils of all studied functional zones in Novokuybyshevsk has not reached the level of approximate permissible concentration (APC), but more than the clark of the world soils and the background indicators. The downward trend in the concentration of copper in the soils of most of the studied functional zones of Novokuybyshevsk in 2018 compared with 2016 and 2017 at the relatively low level of copper content in soils of the industrial area of the city allows to exclude oil refineries from the list of its major anthropogenic sources.

Purpose Tourism development has been perceived as a promoter of city restoration and can also affect the post-war city reconstruction. Questions on how to reconstruct ruined buildings and urban areas through a post-war tourism-oriented approach based on the expectations of residents and tourists profound answers. The purpose of this paper is to adopt the sequential mixed method (qualitative and quantitative) with purposive sampling which is a non-probability method to investigate tourism-oriented approaches in the reconstruction of buildings and landmarks as the core components of urban tourism. Design/methodology/approach The study adopted the sequential mixed method (qualitative and quantitative) to investigate tourism-oriented approaches in the reconstruction of buildings and landmarks as the core components of urban tourism. Findings The findings of the study point that the preferred strategy for the reconstruction of damaged symbolic building is the preservation of the war effects in regard maintaining the buildings’ history to be considered by urban policy makers, urban designers, and authorities. Research limitations/implications The constraint was associated with the time-consuming nature of this type of research. Original documents of the research context and all the interview data were in the Persian language, making the translating process a time-consuming matter. Furthermore, data collection in the area located near the Iran-Iraq border (500 meters) presented a number of security caveats as limitations. Originality/value The research found a majority of tourists and the residents preferred tourism zone where the combination of post-war and natural attraction across riverside area. In other word, most considerable post-war attractions are those that combined with the appeal of the other tourism potentials like eco-leisure tourism. The preferred strategy for the reconstruction of damaged building reconstruction as post-war tourism attractions is the preservation of the war effects in regard maintaining the buildings history rather than reconstruction as the most likely to pre-war conditions with less attention paid to the war effects.
