This urban form, a planned new town founded in 1947 upon a previous, comprehensive British land-development scheme, originally offered a friendly interaction between urban settlement and nature. Hence, this paper outlines how open spaces can be enhanced as an ecological structure, bringing parks, squares, gardens and urban farming into a productive system, both for nature＇s and for people＇s sakes. Following a morphological study, the proposed ecological structure will maintain ecological processes within the urban grid and help to preserve historical and social values, by linking a wide variety of natural and restored ecosystems and landscape features. The adoption of this kind of ecological planning will certainly result in an increase of the urban landscape quality, changing actual planning paradigm and preventing the city from environmental quality decrease.展开更多

The building forms, the distance between the buildings, the setback and the building heights would all affect visibility and were considered closely. Although this research methodology could be applied to any site in different situations, it remains simple and interesting. It can be applied in general, with a change of the variables （setback, distance between buildings, building height, building form）, to any site by both professionals and students who can simply use any CAD program for producing drawing in both the architectural or urban designs phases, hence the importance of this research. Two different building arrangements were proposed and studied： a linear and an L-shaped arrangement. After applying the simulations, it appears that the L-shape offers more visibility to the open space. The outcomes of this study were combined with another research project that studies the same building arrangements to test the possible climatic comfort provided in outdoor spaces in order to encourage the use of open spaces and walkability in the studied area.展开更多

Therefore, according to the type of building structures, the airflow also has different forms. Studies have been conducted on the relation between airflow and pedestrian comfort; however, only few of them have focused on comprehensive urban planning that considers different weather conditions and people＇s ability to adapt. This research focuses on the differences in wind conditions caused by different spatial forms in different seasons. On the basis of a field survey in both summer and winter in a public open space, evaluation standards developed from environmental meteorological data and public feedback were used to evaluate simulation results. Next, several assumptions about canyon orientation and building types were proposed. Wind tunnel and CFD （computational fluid dynamics） simulations were conducted to evaluate the assumptions. The results showed that the canyon orientation significantly affected overall wind conditions and different building structures affected airflow. This research also provides a method to evaluate urban areas that have complicated wind environments.展开更多

In sub-Saharan Africa, towns are urbanizing at a faster pace than earlier predicted. Also, large portions of rural settings have been gradually moving towards urbanization. The Tamale Metropolis has been rated as the fastest-growing metropolis in Sub-Saharan Africa. City planning and concerns about the need for open-space creation have been a major challenge due to poor adherence to standards in the building codes. This study was conducted to assess the role of open space in human settlement development in the Tamale Metropolis. The study sampled the views of 157 residents who stay closed to community open spaces in five suburbs of the metropolis. Key informant interviews were also conducted with officials from the Town and Country Planning Department. The study revealed that most residents spend leisure by taking a walk in the neighborhood or idling in outdoor spaces. Also, the majority of the residents had poor knowledge of institutional and land administration. This often led to non-adherence to regulations and this affects open spaces in the metropolis. Common among residents is also a poor appreciation of the importance of open space and this results in encroachment. The Town and Country Planning Department should institute sanctions and stringent measures to deter offenders. Also, public seminars should be used to educate residents on the need to adhere to planning and building codes. Lastly, the study recommends strong collaboration between the various institutions engaged in land administration to facilitate effective provision and preservation of quality open spaces in the metropolis.展开更多

Environmental ethics places restrictions on freedom in exercising ownership rights and pays more attention to ethical obligations to the environment. The anthropocentric approach should be avoided because it only sees the environment from its commercial angles to satisfy human interests. This research critically describes the reality of the utilization of traditional open spaces in Ubud to become an economic space. The rapid influence of global culture has implications for the practices of capitalist culture within the frame of the tourism industry, resulting in cultural industries, popular culture, hedonic lifestyles and consumerism. This study used a qualitative method. The data was obtained through observation, interviews, literature studies, and documents. The results of the study revealed how traditional open spaces were produced, distributed and consumed by the market. Traditional open spaces were commercialized, traded like goods and services. Traditional open spaces, such as paddy fields, cliffs, telajakan (front part of the house complex), city parks, domestic properties, backyards, cemeteries have been turned into economic spaces to satisfy the taste of tourists. Space is controlled and commodified by capital owners to feed their economic libido while disobeying environmental ethics.展开更多

文摘Finding the shortest path through open spaces is a well-known challenge for pedestrian routing engines.A common solution is routing on the open space boundary,which causes in most cases an unnecessarily long route.A possible alternative is to create a subgraph within the open space.This paper assesses this approach and investigates its implications for routing engines.A number of algorithms(Grid,Spider-Grid,Visibility,Delaunay,Voronoi,Skeleton)have been evaluated by four different criteria:(i)Number of additional created graph edges,(ii)additional graph creation time,(iii)route computation time,(iv)routing quality.We show that each algorithm has advantages and disadvantages depending on the use case.We identify the algorithms Visibility with a reduced number of edges in the subgraph and Spider-Grid with a large grid size to be a good compromise in many scenarios.

文摘This paper studies which building arrangement will provide the maximum visibility to an example of open space proposed in the Abu Dhabi 2030 Master Plan. The building forms, the distance between the buildings, the setback and the building heights would all affect visibility and were considered closely. Although this research methodology could be applied to any site in different situations, it remains simple and interesting. It can be applied in general, with a change of the variables （setback, distance between buildings, building height, building form）, to any site by both professionals and students who can simply use any CAD program for producing drawing in both the architectural or urban designs phases, hence the importance of this research. Two different building arrangements were proposed and studied： a linear and an L-shaped arrangement. After applying the simulations, it appears that the L-shape offers more visibility to the open space. The outcomes of this study were combined with another research project that studies the same building arrangements to test the possible climatic comfort provided in outdoor spaces in order to encourage the use of open spaces and walkability in the studied area.
文摘Airflow in open spaces can significantly affect spatial quality. Therefore, according to the type of building structures, the airflow also has different forms. Studies have been conducted on the relation between airflow and pedestrian comfort; however, only few of them have focused on comprehensive urban planning that considers different weather conditions and people＇s ability to adapt. This research focuses on the differences in wind conditions caused by different spatial forms in different seasons. On the basis of a field survey in both summer and winter in a public open space, evaluation standards developed from environmental meteorological data and public feedback were used to evaluate simulation results. Next, several assumptions about canyon orientation and building types were proposed. Wind tunnel and CFD （computational fluid dynamics） simulations were conducted to evaluate the assumptions. The results showed that the canyon orientation significantly affected overall wind conditions and different building structures affected airflow. This research also provides a method to evaluate urban areas that have complicated wind environments.
文摘Most parts of the world are rapidly urbanizing. In sub-Saharan Africa, towns are urbanizing at a faster pace than earlier predicted. Also, large portions of rural settings have been gradually moving towards urbanization. The Tamale Metropolis has been rated as the fastest-growing metropolis in Sub-Saharan Africa. City planning and concerns about the need for open-space creation have been a major challenge due to poor adherence to standards in the building codes. This study was conducted to assess the role of open space in human settlement development in the Tamale Metropolis. The study sampled the views of 157 residents who stay closed to community open spaces in five suburbs of the metropolis. Key informant interviews were also conducted with officials from the Town and Country Planning Department. The study revealed that most residents spend leisure by taking a walk in the neighborhood or idling in outdoor spaces. Also, the majority of the residents had poor knowledge of institutional and land administration. This often led to non-adherence to regulations and this affects open spaces in the metropolis. Common among residents is also a poor appreciation of the importance of open space and this results in encroachment. The Town and Country Planning Department should institute sanctions and stringent measures to deter offenders. Also, public seminars should be used to educate residents on the need to adhere to planning and building codes. Lastly, the study recommends strong collaboration between the various institutions engaged in land administration to facilitate effective provision and preservation of quality open spaces in the metropolis.
文摘Increasing population and densification of the cities lead to increasing land value by the high demand of land for housing and other infrastructure developments are the reasons that tend to decreasing open spaces in Kathmandu Valley in general,and Kathmandu Metropolitan City(KMC)in particular.Urban open space has been considered as a place that is accessible to all residents and is important in the urban context as such space provides an opportunity as a place for social interaction,networking,recreation,and various physical health exercises.However,different social and economic contexts of the society reflect different patterns of its uses.Two different urban settings(core urban areas having indigenous dominant population and fringe urban areas having migrants’dominant population)have been taken as a basis for analysis in this paper to look at how different urban societies use open spaces differently.Open spaces are not only important for maintaining urban greenery and beauty for the city but are valued for accumulating social capital and enhancing physical well-being to urban communities.These issues are analyzed through the interpretative research methodology by collecting the data through in-depth interviews,key informants’interviews,informal conversational interviews,and nonparticipatory observation from two different urban settings of KMC.
文摘The built environment has a great impact on the quality of urban climate,a comfortable living environment,overheating,and detection of changes in Urban Heat Islands(UHI).Despite the effects that raised outdoor temperatures have on human well-being and health,being in open outdoor spaces is strongly encouraged.This article deals with open green urban areas.The study was focused on searching for the relationships between the various elements,such us outdoor thermal comfort,the urban heat island,green areas,and active leisure time.The well-being in open spaces has be studied on the case of The Path of Remembrance and Comradeship(PATH)in the city of Ljubljana,Slovenia.PATH is a circular recreation ground(almost 33 km long)and passes from the urban to the natural landscape area.PATH constitutes an important element of the urban space and confirms the identity and image of Ljubljana.It is most popular for walking and jogging.Overheating at the PATH was studied using multiple indicators,which were broken down into detail at five sites with different urban morphology,green areas,water,and paved areas.
文摘Open Space Ratio(OSR)是《1961纽约市区划决议案》中居住环境控制的核心概念与重要指标,自1990年代始国内的许多学者引进这个概念,并倡导作为规划控制指标,因此也催生了中文术语"空地率"。本文系统梳理国内有关"OSR"和"空地率"研究的30余年学术文献,基于《1961纽约市区划决议案》的法律文本,对OSR的译名及其概念作出全面的阐释,澄清了OSR指标的意义、应用目的及其范围,辨析了OSR与中文术语"空地率"本质性的概念差异,建议将OSR指标引入控制性详细规划的居住环境控制,调整和完善我国控制性详细规划的指标控制体系。
文摘Open space has various implications in urban development planning and has been integrated in recent urban planning approaches and practices in Nepal.The open spaces are not only important for(re)shaping the urban form but are also important for enhancing urban social life and disaster risk management,particularly for dense cities.As most of the cities in Nepal have been growing haphazardly,the cities lack sufficient open space.However,the value of open space in dense cities like Kathmandu has been recognized more after the Gorkha Earthquake 2015 as the open spaces were extensively used for risk relief,treatment,recovery,and rehabilitation during and after the earthquake.With this background,this paper presents the major planning initiatives in Nepal and discusses how recent urban plans have provisioned and initiated open spaces development by reviewing concurrent urban planning practices,particularly reviewing Periodic Plans,Integrated Urban Development Plan,Smart City Plan,and Land Development Plan.The development of open areas has not been given much attention in the earlier urban planning practice but recent urban development planning has emphasized with a special focus which is very important for sustainable and safer city development and is expected to address the current bulging urban issues of spatiality and sociability.Therefore,it is very important for integrating open space implications in city planning and such open space should be conceptualized according to the city’s geography,landscape as well as socio-cultural contexts.
文摘AUSTRALIA is known as a country with plenty of space, and comparatively few people to populate it. When you think about the fact that there are six cities in China with a greater population than the whole of the 3.5 million-square-km area of the Great Southern Land, perspectives may change. It is one of the backdrops to the formation of the Australian character. Many cannot just go around the corner for their weekly groceries. Sometimes it may even be delivered by airplane. In some regions, it might be a few hours＇ drive to a neighbor＇s place.
文摘This paper aims to examine the phenomenon of commodification of traditional open space into commodities which results in the destruction of environmental ethics. Environmental ethics places restrictions on freedom in exercising ownership rights and pays more attention to ethical obligations to the environment. The anthropocentric approach should be avoided because it only sees the environment from its commercial angles to satisfy human interests. This research critically describes the reality of the utilization of traditional open spaces in Ubud to become an economic space. The rapid influence of global culture has implications for the practices of capitalist culture within the frame of the tourism industry, resulting in cultural industries, popular culture, hedonic lifestyles and consumerism. This study used a qualitative method. The data was obtained through observation, interviews, literature studies, and documents. The results of the study revealed how traditional open spaces were produced, distributed and consumed by the market. Traditional open spaces were commercialized, traded like goods and services. Traditional open spaces, such as paddy fields, cliffs, telajakan (front part of the house complex), city parks, domestic properties, backyards, cemeteries have been turned into economic spaces to satisfy the taste of tourists. Space is controlled and commodified by capital owners to feed their economic libido while disobeying environmental ethics.
文摘The reconstruction of historical sites,while a controversial practice,has been common in both Germany and China to mitigate the cultural losses incurred during wars and subsequent redevelopment.This paper contributes to the broader discourse on reconstruction by examining the critical signifcance of integration between the‘old'and‘new',which means establishing a smooth and close transition between the reconstructed sites and the surrounding urban environment,as well as the key role of open space in facilitating this integration.Through morphological analysis and site surveys,the Yanghe Tower in Zhengding,China,and the Dom-Römer in Frankfurt,Germany,are compared in this paper.The comparison reveals that the integration issue related to Yanghe Tower was not adequately addressed because the key role of open space was neglected.This paper also examines the sociocultural factors that infuenced the design strategies of the two projects,suggesting that future Chinese reconstruction eforts can signifcantly beneft from attention to the key role of historical open spaces.
文摘BACKGROUND High complex anal fistulas are epithelialized tunnels,with the main fistula piercing above the deep external sphincter and the internal opening approaching the dentate line.Conventional surgical procedures for high complex anal fistulas remove most of the external sphincter and damage the anorectal ring.Postoperative loss of anal function can cause physical and mental damage.Transanal opening of the intersphincteric space(TROPIS)is an effective procedure that completely preserves the external anal sphincter.However,its clinical application is limited by challenges in the localization of the internal opening of a fistula and the high risk of complications.On the basis of our clinical experience,we modified the TROPIS procedure for the treatment of treating high complex anal fistulas.CASE SUMMARY A patient with a high complex anal fistula located above the anorectal ring underwent modified TROPIS,which involved sepsis drainage and identification of the internal opening in the intersphincteric space.The patient with the high complex anal fistula recovered well postoperatively,without any postoperative complications or anal dysfunction.Anal function returned to normal after 17 months of follow-up.CONCLUSION The modified TROPIS procedure is the most minimally invasive surgery for anal fistulas that minimally impairs anal function.It allows the complete removal of infected anal glands and reduces the risk of postoperative complications.Modified TROPIS via the intersphincteric approach is an alternative sphincter-preserving treatment for high complex anal fistulas.
