Ecological Interpretation of Regional Elements in the Design of Local and Korean Urban Public Facilities

In the planning and construction of modern city, how to highlight the regional elements of the city and show the ecological design of the city has become the key content. Public facility design is an important part of urban construction. On the one hand, it is directly related to the public life, and on the other hand, it is closely related to the urban context and future development. Based on this, this paper mainly discusses the regional elements and ecological interpretation in the design of urban public facilities in our country and South Korea, aiming to provide reference for the subsequent design. To answer our research question, we begin by constructing a sample of all Chinese non- financial firms listed in the A-share market between 2007 and 2018 (n=29,181). We obtain financial statement data from the China Stock Market and Accounting Research (CSMAR) database. We obtain individual audit partner’s demographic information, such as gender and educational background, from the Chinese Research Data Services CARD database and the China Institute of Certified Public Accountants (CICPA) website. We lose 1,674 observations because we cannot find the signing auditor’s demographic information needed in the Heckman’s model and PSM; we further delete 4,783 observations because they do not have enough firm financial data to compute the variables used in our empirical tests; we exclude 672 observations because the annual reports are signed with three auditor signatures. Our final sample consists of 22,052 firm-year observations.

Characteristics of spatial mobility layout

Spatial fluidity is an important form of spatial organization in architectural design, because it can affect the behavior of building users in the building. Therefore, spatial fluidity is also the most basic and core content in space design. Therefore, how to realize the communication and interaction between people and places through the fluidity of space has become an urgent problem to be solved in the construction of modern cities. This paper introduces the concepts of "mobility" and "layout" in architecture through the research method of theoretical analysis, so as to help explain the characteristics existing between them, and discuss the characteristics of spatial mobility layout. Excellent spatial fluidity design is extremely important for some special environments such as enterprises and libraries. It can provide a clear sense of direction and space, reduce unnecessary flow space, and thus improve work efficiency and use requirements.

Low-Carbon City Building and Green Development: New Evidence from Quasi Natural Experiments from 277 Cities in China

As a high-quality and sustainable growth model, green development has different economic, ecological, and social dimensions and is strategically important for the realization of modern city construction and the sustainable development of human society. The low-carbon city pilot policy (LCCP) is an innovative initiative for promoting green urban development and building a harmonious society in China. Based on balanced panel data from 277 prefecture-level cities from 2007 to 2020, this paper measures the level of urban green development in terms of three dimensions: green economic growth, ecological welfare enhancement, and social welfare increase. This paper also adopts a multi-period difference-in-differences (DID) method for investigating the impact of LCCP on green development with the panel dataset. The results of the study show that: (1) LCCP is generally beneficial to urban green development, and the results still hold after a series of robustness check analyses. (2) The results of the mechanism analysis show that the construction of low-carbon cities has improved the level of green technology innovation, thereby promoting the level of regional green development. Environmental regulation has a masking effect between low-carbon city construction and green development in this study. When environmental regulation is controlled for, the coefficient of the effect of LCCP on green development increases, reflecting that environmental regulation also plays an important role between the two. (3) According to the geographical location, whether it is a resource-based city, and the city cluster, we found that the low-carbon city pilot policy has a significant positive role in promoting green development in the central region, non-resource-based cities, and the Jing-Jin-Ji, but not in the eastern region, the western region, the Yangtze River Delta and Pearl River Delta. We also found that in resource-based cities, this effect presents a significant negative relationship. The above findings enrich the literature on low-carbon city pilot policies and green development and provide Empirical evidence for relevant countries and regions to carry out low-carbon city pilots.

Development of a search and rescue robot system for the underground building environment

AbstractThe underground building environment plays an increasingly important role in the construction of modern cities. To deal with possible fires, collapses, and so on, in underground building space, it is a general trend to use rescue robots to replace humans. This paper proposes a dual‐robot system solution for search and rescue in an underground building environment. To speed up rescue and search, the two robots focus on different tasks. However, the environmental perception information and location of them are shared. The primary robot is used to quickly explore the environment in a wide range, identify objects, cross difficult obstacles, and so on. The secondary robot is responsible for grabbing, carrying items, clearing obstacles, and so on. In response to the difficulty of rescue caused by unknown scenes, the Lidar, inertial measurement unit and multiview cameras are integrated for large‐scale 3D environment mapping. The depth camera detects the objects to be rescued and locate them on the map. A six‐degree‐of‐freedom manipulator with a two‐finger gripper is equipped to open doors and clear roadblocks during the rescue. To solve the problem of severe signal attenuation caused by reinforced concrete walls, corners and long‐distance transmission, a wireless multinode networking solution is adopted. In the case of a weak wireless signal, the primary robot uses autonomous exploration for environmental perception. Experimental results show the robots' system has high reliability in over‐the‐horizon maneuvering, teleoperation of the door opening and grasping, object searching, and environmental perception, and can be well applied to underground search and rescue.

Application Research and Case Analysis of Landscape Design in Artificial Intelligence Platform

Modern landscape greening plays an important role in the construction of modern cities and plays a positive role in improving the natural environment of cities and building a good image of cities. With the continuous progress of society and technology, human’s understanding of artificial intelligence is deepening, and intelligent technology is gradually integrated into all aspects of life. Because media technology has rich design elements and can carry out rich design structures, it will be more intuitive to use multimedia means for garden landscape design. Therefore, for meeting people’s requirements for the diversification of modern urban gardening construction, this study makes a deep analysis of the current status and problems of landscape design and tries to study the effective application methods of artificial intelligence technology in landscape design, to promote the combination of landscape design and artificial intelligence design. At the same time, the combination of AI lighting planning, AI water landscape planning, AI sprinkler planning, and AI paving planning is used to illustrate the application of AI in the specific project design of landscape design. The use of artificial intelligence not only promotes the innovation and optimization of landscape design, but also ensures the quality of modern landscape design and effectively improves the efficiency of modern landscape design.

Behavior of isolated floating pile adjacent to deep excavation reinforced by dual-row batter pile wall

The construction of modern city consists of many underground facilities, and one major concern is how to construct them safely and efficiently. Thus, the excavation-induced pile response needs to be evaluated. Dual-row batter pile wall (DRBPW) exhibits better performance than traditional dual-row vertical pile wall (DRVPW) in foundation pit engineering. However, the study of single pile subjected to excavation-induced soil movement behind DRVPW is rather limited, needless to say that of the DRBPW. An explicit finite difference method (FDM) was utilized to obtain the responses of isolated floating single pile (IFSP) near deep excavations braced by DRBPW. The responses of IFSP in the vicinity of foundation pit reinforced by DRBPW were compared to that of the DRVPW. The pile length, distance of pile from wall, excavation depth, working load, and Young’s modulus of pile were considered in the parametric study. The conclusions were as follows: (1) The DRBPW can minimize the influence on the existing pile; thus, the induced lateral displacement and bending moment of pile retained by DRBPW are smaller than that of DRVPW. (2) The excavation depth, pile location, and pile length have significant influence on the responses of IFSP adjacent excavation, while the working load and Young’s modulus of pile have diminutive influence. (3) The influence zone induced by excavation can be divided into two areas. The primary influence zone is the severely affected area where the induced deformation and bending moment are remarkable. The secondary influence zone is the moderately affected area where the induced deformation and bending moment are mild. The primary influence zone is within twice of the excavation depth. The secondary influence zone is 2.0–3.0 times that of the excavation depth. (4) The pile toe of IFSP has considerable lateral displacement during excavation, and attentions should be paid to the whole pile shaft during construction.

Construction Safety Management Report for High-Rise Buildings

Abstract Due to the current rapid economic development, all walks of life have also achieved considerable development. Among them, the construction industry is particularly prominent. In the process of modern city construction, high-rise and super high-rise buildings are more and more common. As we can see, there are a lot of accidents happening at the construction site. In order to find the CSFs for safety management, the author uses SPSS software to collect the data from survey and then performs an analysis. This way, the key factors have been found to affect the safety management. In the meantime, the case study is used to verify the key factors and get the correlation between different CSFs. In order to reduce the possibilities of safety problems at construction sites and propose some suggestions to existing problems, the author combines the current situation and CSFs. The aim of the article is to help companies manage construction sites more efficiently, thus promoting the healthy development of the construction industry in Poland.

Numerical Analysis of the Influence of Foundation Pit Blasting on a Nearby Metro Tunnel

It is important to guarantee the safety of adjacent underground structures during the foundation pit blasting excavation of modern city construction. The blasting excavation construction of a large, deep foundation pit near an existing metro station of Guangzhou Metro Line 3 is used as the example in this study. Based on blasting vibration field test results, the influence of blasting dynamic load on the lining of an adjacent metro tunnel is numerically analyzed in simulation using Fast Lagrangian Analysis of Continua 3D (FLAC3D), and the relationships between the blasting vibration velocity and stress and the displacement of the metro tunnel lining are obtained. The results show that the stress of lining structure is within the allowable range under the experimental blasting conditions, the lining displacement increases linearly with the applied dynamic vibration velocity, and the vertical displacement of the lining is more obviously affected than the horizontal displacement by the dynamic load. This study can be used as a basis for the control of blasting vibration in a complex urban environment. Its practical application shows that the proposed blasting plan and parameters are reasonable and effective.

Analysis on Reconstruction Design of Old Urban Roads

<p>With the continuous development of cities, the urban roads built in the early days can no longer meet the needs of modern urban transportation. Therefore, in the current urban development and construction process, the reconstruction of old roads is the key construction content. At the same time, the transformation of old urban roads is also an inevitable requirement to improve the urban road system and improve the level of urban communication infrastructure construction and transportation service capacity. The reconstruction of old roads meets the requirements of the overall planning and construction of modern cities, and plays a vital role in promoting the development and progress of urban economy and improving the quality of life of urban residents. In the process of urban old road reconstruction, because the original urban road environment is very complex and involves many factors, the rational design of the construction scheme of the old road reconstruction project is the key factor affecting the effect of the old road reconstruction. This paper makes an in-depth exploration and analysis of the old road reconstruction design of urban roads, and puts forward scientific and reasonable suggestions in combination with the actual situation, so as to provide reliable theoretical support for improving the old road reconstruction level and promoting the urbanization development process in China.</p>

Urban Planning by Le Corbusier According to Praxeological Knowledge

The city is formed as a mosaic of various elements which affect its attractiveness. These elements range from location attributes, through economic opportunities, to social aspects. Therefore, urbanity and urban planning should be considered in a multi-dimensional context. In the paper we address the problem of urban planning by Le Corbusier according to praxeological and system knowledge. From praxeological point of view an active human being takes his/her choice between various possibilities by preferring one of these possibilities to the others, and by manifesting it by her actions. The same applies to the design process. Due to this fact, the scientific design process can be treated as a systematic rational reconstruction of the designer’s behaviour. Such a reconstruction requires previous reflection on designer’s work, as well as some consideration and design experience, thus know-how knowledge based on methodological knowledge. In the paper several city visions of Le Corbusier, as well as the characteristics and organisation of his design process are analysed. Le Corbusier’s innovative design ideas resulted from industrialisation changes and motorisation accelerating progress, which gave foundation to a new urban array. This array based on strict geometric forms, regularity and repetition determining standard. Thanks to his theories, Le Corbusier established principles of modern city construction and planning. Although some doubts were expressed as to the scale of centralisation of the cities designed by him and his class-based conception, he was awarded that overall welfare of the individual living in a city was the quality of built environment. Therefore, his designed creations were not only functional but they also produced emotions. The analysis of his prolific design activities allows us to state that the organisation of his architectural and urban planning process was very efficient and complex. The city concepts proposed by him were the subject of analysis by generations of designers. Also now, they can still be the basis for modelling virtual and navigable cities by modern planners. Le Corbusier’s comprehensive approach to modern city planning showed that research activities, that is theoretical thinking, and production activities, that is practice, are linked methodically. Therefore, urban planning should be understood not only as a projection of the possibilities of architecture, but as a multidisciplinary process. Due to this fact, an urban plan, as a result of that process, should be a synthesis of various social, industrial and economic aspects.

Can a future city enhance urban resilience and sustainability? A political ecology analysis of Eko Atlantic city, Nigeria

There is a consensus on the detrimental impacts of erosion and storm surges on the coast of Lagos, Nigeria but no agreement on whether the proposed Eko Atlantic City (EAC) adaptation project would lead to urban resilience and sustainability. This on-going modern city construction on the Atlantic Ocean is presented by its planners as a permanent solution to ocean intrusion and a model of adaptation, urban development, and economic growth, suggesting ‘all good things go together’ even in a changing climate. In this study, I explore the costs and risks of this future city to Greater Lagos in the broader context of resilience planning, capitalist urbanisation, disaster risk, and climate change. I draw on newspaper articles, in-depth interviews, and focus group discussions to unravel the relations of power, politics, and discourses that have served to legitimize and re-position the project as a positive-sum adaptation despite public concerns over maladaptation. Informed by urban political ecology, this paper reveals that while the EAC might hold promises of short-term storm mitigation on Victoria Island, in the long run it will re-shape the physical, economic, political, and socio-cultural ‘riskscape’ of Lagos with particular implications for marginalized communities and future generations. This developing country case study presents an opportunity for further discussion on adaptation planning, disaster risk reduction, and city transformation.

A Study on the Evolution Rule and Culture Analysis of the Spatial Form of Ancient Towns in Yuanshui River Basin

The drainage basin of Hunan Yuan River is mysterious because of its multi-ethnic culture. A lot of cities and towns were built along the Yuanshui River because of its convenience in water transportation. Yuanshui River is a complete, unique, diverse and an inseparable group culture system with a series of features like environment complexity, multi-culture integration and long history. This article aims at providing a reference to the construction of modern cities and towns in this drainage basin through a thorough study on the evolution rule of the form of the historical cities and towns along Yuanshui River and a study on the unique multi-ethnic culture features that influenced the form of the ancient towns.

The Conservation of the Industrial Heritage Road — Taking "Tianjin Tractor Factory" Site Revival as an Example

Industrial heritage or problems in modern city construction has been the focus of concern and controversy, Tianjin as an important port city of China in modern, the previous light and heavy industrial production activities in the city left numbers of traces. There is no longer have traditional industry vitality in these industry base, we should be how to locate it? We have make great errors in "construction" and got the demolitions in our city, but also we accumulated a lot of experience too. Through careful investigation we found both not indulging in idle space in the old city has become a knot, also not be reckless of the cultural context in which the demolition and reconstruction, After all we are in decision-making mistakes in a short moment lost the "Tianjin ancient fossils -- old Chengxiang". To achieve sustainable city construction, we should respect the continuity of development of things, equilibrium and the public. Based on the transformation of "Tractor factory of Nankai District in Tianjin as example, we hope to explore and find some strategy in economy, balanced and sustainable development of industrial building heritages.
