Modern urban surface is gradually covered by water blocking material in China, it has been increasing the city and its surrounding areas on the ecological significance of the "man-made desert" effect. In this paper, taking Xi'an as an example, the authors discuss the possibility to build a whole city water environment through the transformation of city hardened of surface. Xi'an has obvious characteristics of seasonal rainfall, taking the transforming of city's eco-permeable surface as a starting point, will contribute to the gradual recovery of the city’s function as an ecological nodes and the basic "metabolism"; restoration and reconstruction of urban water environment, improving the living environment, highlighting the "Chang’an eight water" pattern and context features of the city.

The increasingly advanced developmentnin the city of Bogor has an impact on the carrying capacity of the environment. One that is rarely in the spotlight is about the decreasing number of lakes in Bogor. In urb an areas such as Bogor City, local people refer to the lakes as situ or setu. The existence of these “Situ” affects the water system, both in this city and in the surrounding areas. Although “Situ” play a vital role in maintaining the balance of urban water systems, they have not received sufficient attention in the planning documents for the City of Bogor, both annual and medium-term documents. The rapid development of the city affects thequantity and quality of urban lake water in the city of Bogor. These “Situ continue to experience physical and ecological degradation which increases the threat to the health of the population of the city of Bogor. This situation shows that the site has not been managed and functioningnproperly. Human and natural disturbances such as encroachment, garbage disposal, and untreated waste have polluted “Situ” water and reduced its volume capacity. Most of the lakes in the city of Bogor experience disturbances in damaged environmental conditions. This paper seeks to examine th e condition of the “Situ” in Bogor City and its problems based on literature studies from previous researchers. The results of the research will provide recommendations based on scientific theories and existing regulations, both national regional regulations and regional regulations in Bogor City

Young people are important to cities, bringing skills and energy and contributing to economic activity. New technologies have led to the idea of a smart city as a framework for city management. Smart cities are developed from the top-down through government programmes, but also from the bottom-up by residents as technologies facilitate participation in developing new forms of city services. Young people are uniquely positioned to contribute to bottom-up smart city projects. Few diagnostic tools exist to guide city authorities on how to prioritise city service provision. A starting point is to understand how the youth value city services. This study surveys young people in Braamfontein, Johannesburg, and conducts an importance-performance analysis to identify which city services are well regarded and where the city should focus efforts and resources. The results show that Smart city initiatives that would most increase the satisfaction of youths in Braamfontein  include wireless connectivity, tools to track public transport  and  information  on city events. These  results  identify  city services that are valued by young people, highlighting services that young people could participate in providing. The importance-performance analysis can assist the city to direct effort and scarce resources effectively.

Michel Butor, born in 1926, one of the leaders of the French New Novel movement, has written only four novels between 1954 and 1960. The most famous of them is La Modification (Second thoughts), published in 1957. The author of the paper analyzes two other Butor’s novels: L’Emploi du temps (Passing time) – 1956, and Degrés (Degrees) – 1960. The theme of absence is crucial in both of them. In the former, the novel, presented as the diary of Jacques Revel, a young Frenchman spending a year in Bleston (a fictitious English city vaguely similar to Manchester), describes the narrator’s struggle to survive in a double – spatial and temporal – labyrinth. The first of them, formed by Bleston’s streets, squares and parks, is symbolized by the City plan. During his one year sojourn in the city, using its plan, Revel learns patiently how to move in its different districts, and in its strange labyrinth – strange because devoid any centre – that at the end stops annoying him. The other, the temporal one, symbolized by the diary itself, the labyrinth of the human memory, discovered by the narrator rather lately, somewhere in the middle of the year passed in Bleston, becomes, by contrast, more and more dense and complex, which is reflected by an increasinly complex narration used to describe the past. However, at the moment Revel is leaving the city, he is still unable to recall and to describe the events of the 29th of February 1952. This gap, this absence, symbolizes his defeat as the narrator, and, in the same time, the human memory’s limits. In Degrees temporal and spatial structures are also very important. This time round, however, the problems of the narration itself, become predominant. Considered from this point of view, the novel announces Gerard Genette’s work Narrative Discourse and his theoretical discussion of two narratological categories: narrative voice and narrative mode. Having transgressed his narrative competences, Pierre Vernier, the narrator of the first and the second parts of the novel, who, taking as a starting point, a complete account of one hour at school, tries to describe the whole world and various aspects of the human civilization for the benefit of his nephew, Pierre Eller, must fail and disappear, as the narrator, from the third part, which is narrated by another narrator, less audacious and more credible.
