In recent years, rainfall-induced waterlogging has become a common hazard in the highly urbanized coastal city of Chattogram, Bangladesh, resulting in a high magnitude of property damage and economic loss. Therefore, the primary objective of this research was to prepare a waterlogging inventory map and understand the spatial variations of the risk by means of hazard intensity, exposure, and vulnerability of waterlogging. In this research, the inventory map and factors influencing waterlogging hazards were determined from a participatory survey, and other spatial data, including land elevation, population, and structural data, were collected from secondary sources. The analytical hierarchy process was applied to measure the hazard intensity, and the exposure and vulnerability were estimated by overlaying the spatial data onto the hazard intensity map. A total of 58 locations were identified as waterlogging affected, which covered ~8.42% of the city area. We showed that ~3.03% of the city area was greatly vulnerable to waterlogging in terms of their social, infrastructure, critical facilities, economic, and environmental vulnerabilities. The obtained waterlogging risk index map suggested that ~2.71% of the study area was at very high risk, followed by moderate (~0.15%), low (~3.89%), and very low (~1.67%). The risk analysis presented in this study was a simple method that can be applied to assess the relative risk of waterlogging in different regions, and the results were applicable to the prevention and mitigation of waterlogging for Chattogram City.

Flooded Areas

GIS with its capacity for storing and displaying spatial data can be an excellent tool for the management of flooding problems in HCM city. The system can visualize a the overall flooding status of the city, for example i) on a specific rainy day ‘x’ in the past, the locations of flooded areas, their respective depths and durations; ii) how flooding developed at a certain location ‘y’ in the city over the last several years; iii) or the most serious flooding areas of the city, etc. An advantage of the system is its capability to link flooding information with existing related geographic, landmark and drainage systems. This article presents such a system in managing flooding information. The application is developed using the vb.net program and ArcObject library. The system is built to run as independent software on the platform of ESRI ArcGIS Engine 9.2. The application has been piloted effectively for a set of sample data of HCMC. Initial results show this is a promising system to support management of information flooding in Ho Chi Minh City.

– Within the last 20 years, there has been witnessed a significant increase of the urban population of Sarajevo, as a result of economic and social migrations. Consequently, this has caused an increasing demand for new housing which is mainly profit-oriented without any beneficial social, environmental or cultural implication. Primary objective of this research is to analyze the current situation and to assess the quality of the buildings not only as a housing solution, but as a complex that unites the community who inhabits it. This research will be conducted in a qualitative manner in analysis and statistical approach over the data related to the urbanization, building standards and positive effects of the building. Newly built parts of settlements Otoka and Stup will be used as case studies, since these parts of the city are most influenced by the mass production of the new housing solutions. This paper stresses out the correlation between high demand for the new housing and decreased quality of the housing without respecting minimum spatial and environmental standards, without basic amenities, social infrastructure and recreational and cultural activities. There is a need for improvements in contemporary housing design that will reflect with positive impacts on social, environmental, economic and cultural aspects of urban living.

Among contact sports, the practice of martial arts offers a greater risk of causing dental trauma and fractures as contact with the face is more frequent. The primary objective of the research is to evaluate the incidence of mouthguard use, and the secondary objective is to verify which type has a greater predominance and the difficulties in its use correlating to the type of mouthguard used. A documentary study was carried out with 273 athletes of different contact sports, among them: MMA, Boxing, Muay Thai, Jiu-Jitsu, and Taekwondo of the city of Campos dos Goytacazes, Rio de Janeiro, Brazil. It was concluded that the most commonly used mouthguard is PB Boils and Bites - Type II and its level of approval is poor, interfering with the athletes’ performance, mainly in relation to the breathing factor.

The global cities of the world are witnessing a visible disconnection of everyday life. In India the Smart City guidelines acknowledge the need to counter the growing social detachment and intolerance by encouraging interactions. They go further in identifying that preserving and creating of open spaces must be a key feature of comprehensive urban development. Most social relations are cemented within open spaces at the neighbourhood level. Previous studies examine the association between the attributes of neighbourhood open spaces and social activity but neglect to view the issue comprehensively. The present study turns to Lefebvre’s Unitary Theory which states that open space is a result of three forces; 1) perceived space which is the physical dimension and material quality identifiable by the senses; 2) conceived space created by planners and other agents as plans and documents; and 3) lived space which is shaped by the values attached and images generated through user experience. For open space conducive to social interactions these three aspects must work in tandem. With this consideration a framework of criteria and indicators is developed and used to measure and compare the open spaces in select neighbourhoods in Europe and India. The investigation thus reveals differences in all three aspects of neighbourhood spaces. It also reveals a discrepancy between the planning standards formulated and employed by the city authorities in providing the spaces and the actual needs of the community. The research aims to address this gap. The study of the Indian cases lays foundation for the use of the framework to measure open spaces in association with social cohesion and thereby contribute to the enhancement of the social infrastructure of the City.

Saturday, 18 December 2010 was the first of a two day complete closure of all London area airports due to freezing temperatures and approximately five inches of snow. A week later on December 26th, New York City area airports closed in a similar manner from the sixth largest snowstorm in NYC history, blanketing the city approximately twenty inches of snow. Both storms grounded flights for days, and resulted in severe delays long after the snow stopped falling. Both London and NYC area airports produced risk communications to explain the necessity for the closures and delays. This short flash news report examines, in turn, the risk communications presented during the airport closures. A background is provided to understand how the risk perceptions differ between London and NYC publics. Finally, it compares and contrasts the perceptions of the decision making process and outcomes of the closures, which continue to accumulate economic and social impacts.

High-rise construction results in the need of planning of infrastructure facilities, taking into account the increase in loading, as high-rise construction allows to place considerably bigger number of residents in the limited territory. For this purpose it is necessary to estimate the required and actual level of providing the population with each particular type of the facilities of social infrastructure. The compliance of required and actual level of providing can be characterized as the territorial balance, while the discrepancy acts as the territorial imbalance. The article is devoted to the development of such instruments of planning of urban development, which will allow to create the qualitative urban environment, founded on the territorial balances. Namely, it is devoted to the calculation of level of providing the population with the facilities of social infrastructure, to the determination of level of the imbalance in absolute and relative units and also to the ranging of imbalances on urgency of their elimination. The size of the imbalance is of great importance for planning and realization of managerial influences from the executive authorities, operating the city development. In order to determine the urgency of realization of actions for the construction of facilities of social infrastructure it is offered to range the imbalances according to their size, having determined the deviation size from balance, which is so insignificant that it does not demand any managerial influences (it can be characterized as balance) and also the groups of the imbalances, differing in urgency of managerial influences, directed to the decrease and elimination of the revealed imbalance.
