Looks at pavings and how they contribute to the character of villages, towns and cities. Surveys the history of pavings from Roman times, and discusses the different types of paving which can be found. Concludes with an outline of legal controls and planning policies.

This paper sets out describe the creation of sustainable urban planning concepts based on optimized urban landscape functioning. It gives an account of the formation and transformation processes of natural and artificial streaming structures.

The paper examines the present‐day approaches to the environmental assessment and zoning of urban territories. This was achieved by creating the conceptual methodological basis for the assessment and classification of urban landscapes.

Based on an analysis of the urban planning development of the Moscow agglomeration, principles have been proposed for the shaping of sustainable urban planning structures – landscape planning that can be applied to the management of the territorial growth of large cities and urban agglomerations. First, the shaping and reconstruction of the city structure, including the structure of land management, as well as the mutual arrangement of functional areas, should be based on the need to preserve the axes – the lines and planes of mass, energy and information transfer of landscapes of various orders. Second, the order of preserved landscape axes depends on the organisational complexity of a territory. Third, assessment of the sustainability of the structure of a city and agglomeration should be based on the criteria of river systems along their borders, such as the quantity and composition of water, its temperature, retention of the annual functioning cycle and biodiversity. Finally, urban planning control regimes should be established across the entire city and they should be determined by the position of the territory in the city's landscape structure.

This work will provide a better understanding of integrated environmental systems to enable development of best management practices in the city of Moscow.

Much of the housing stock in the UK is built on shrinkable clay soils, particularly in the south‐east of the country. When the moisture content of the clay soils is reduced the clay shrinks causing downward movement. This extraction of moisture from the clay may occur in a number of ways, but the main causes are either prolonged periods of dry weather (a combination of high average temperatures and low average rainfall) or tree roots extracting the moisture from the soil in close proximity to a property. The most extreme cases occur when a combination of the two causes is evident. Over the past few years the UK has seen some of the driest periods of weather on record which has meant that clay soils have not been able to replenish their seasonal moisture loss during the winter months. This has caused an increase in the number of cracks appearing in properties and a rise in the number of subsidence claims made against insurance companies. If climatologists are right about global warming, then subsidence damage has become an endemic hazard of home ownership. Prolonged periods of dry weather will continue to cause serious and very expensive damage to the country’s housing stock. The annual subsidence bill of £300 million can only be reduced by improving education and communication within the construction industry and encouraging house owners to look after their investments more carefully. This paper attempts to identify how the cost of subsidence damage can be reduced despite the changes in climate conditions.

When observing the work of Brazilian Sociology and Anthropology, it is apparent that the study of childhood, particularly concerning play and toys, has received little attention. A quick evaluation in this area shows that few existing works appear in the fields of Psychology and Education, the first mostly concerned with the psychology of development and the latter with the question of learning.¹

This study examines the relationship between quality and quantity of open space in residential areas and the sense of community of Chinese older adults in Hong Kong.

A survey was conducted with 257 adults aged 55 and over in Kwun Tong, Hong Kong. The quality of open space was assessed from four dimensions: social and recreational facilities, entrance, location and environment. Geographic information system (GIS) was used to evaluate the quantity of open space in terms of size and amount.

The result shows that the environment has a strong influence on the sense of community, while the quantity of open space does not. The results provide urban planners with evidence for open space planning in the future. Urban planners should consider building more people-oriented environment; such as green areas instead of merely increasing the size, amount and facilities of open space. The Hong Kong Government also needs to review the current standardised planning guideline in order to maximise the social connection of older adults.

This cross-sectional study tried to understand the relationship between the quality and quantity of open spaces and sense of community in Chinese older adults in Hong Kong. It is one of the few studies to simultaneously examine both the quality and quantity of open spaces when studying its relationship with sense of community.

The purpose of this paper is to review available technologies, analyse their features, propose a new approach of 3D sand mould printing based on line forming, introduce the manufacturing principle and show advantages of this approach, especially for larger parts with large Z steps in the build, such as 2 mm stepwise.

This paper introduces 3D sand mould printing, compares and analyses technological process and existing fabrication approaches among available technologies first. Then, a new approach of 3D sand mould printing is proposed to improve build speed. In addition, the proposed system will be analysed or benchmarked against existing systems.

A new approach based on line forming of sand mould printing is put forward by reviewing and analysing available technologies, to improve build speed from the aspect of basic moulding movement instead of optimization of moulding methods and process parameters. The theoretical calculation and analysis shows that build speed can be improved greatly, and it is more suitable for the manufacture of large-scale casting’s sand mould when considering dimensional accuracy and printing error, as well as uniformity of each layer.

The specific implement scheme of line forming and nozzle’s specific structure of this new approach need further study.

Much higher build speed of 3D sand mould printing with new approach brings evident implication for moulds companies and manufacturing industry, having a far-reaching influence on the development of national economy.

This paper reviews available technologies and presents a new approach of 3D sand mould printing for the first time. Analysis of the new approach shows that this new method of sand mould printing can boost build speed greatly. So, its application prospect is great.

Maintenance costs are increasing as industry is trying to use automation and take advantage of advances in technology. Management needs to plan and control maintenance costs. Adequate techniques for developing standards for maintenance costs are not available. This article outlines such a technique and suggests means of comparing the maintenance performance efficiency of different plants/companies.

The aim of this paper is to investigate the sediment and pollution profiling and particle size distribution with depth within permeable paving structures, both with and without a geotextile.

Test rigs set up in an earlier pilot study were used for four separate but linked studies. Street dust was applied to rigs C and D to determine the retention of sediments. Heavy metals together with street dust were applied to rig A and B (previously control rigs) to determine the effect of sediment on the pollution removal capabilities of the test rigs. Following the application of sediment, rigs A and B were carefully taken apart to determine pollution profiles and particle size distributions.

The findings reveal that sediment does have an effect on the metal removal capabilities of permeable paving systems, but there was minimal difference between the rigs with a geotextile and without. Pollution profiling within the test rigs identified that the greatest concentration of metals was in the surface sediment and that both rigs removed similar percentages but the concentrations of metals were distributed differently. It was also found that after between 10 and 15 years of sediment application paving rigs began to “block” causing reduced infiltration rates. Unfortunately it is difficult to explain the variations of particle size distributions found with depth in the paving structure. It had been expected to find progressively higher proportions of finer material with depth. However, the reverse was true, with a higher proportion of fines in the sediment applied to the surface and a progressive increase in the proportion of coarse material with depth

The conclusions confirm the effects of sediment within a permeable paving structure and indicate the loading at which the infiltration rates become affected. These results may help to determine a maintenance programme, however this would require further research.

The paper provides a comparative study on pollution and sediment profiling within a permeable paving structure both with and without the inclusion of an upper geotextile. It provides valuable insight into the amount of sediment on paving before it becomes blocked. The methodology and results reported in this research could be used for further studies to provide more evidence as to whether the inclusion of an upper geotextile is beneficial.

This paper aims to investigate the situation and evolution of sustainability performance in China.

This paper adopts the global Malmquist-Luenberger (GML) productivity index based on data envelopment analysis and Tobit regression for analysis.

The results indicate the following: China’s sustainability performance has been improving since 2005 and is closely related to the national development strategy and supportive policy; regional gaps in sustainability are a prominent problem represented by the fact that South Central China is becoming a sustainability collapse zone; interprovincial heterogeneity is evident with the varying development speed and conditions; and the level of sustainability performance has a significantly positive correlation with the urbanization rate, investment completed in the treatment of industrial pollution, government appropriation for education and per capita area of paved roads, but it has a negative correlation with the possession of private vehicles.

As an application, this study assessing the GML productivity index of 30 provinces in China from 2005 to 2015 and analyse the sustainability performance on three regional levels (i.e. country level, regional level and provincial level). Tobit regression is also applied to recognize the factors related to the GML index with the results taken as references for policy suggestions. The results have implications for a comprehensive understanding of China's sustainability performance and policymaking in this field.
