Improving Urban Retirees’ Well-Being by Leisure Activities

This research is to investigate urban retirees’ needs and suggest the design direction of leisure facilities. Unlike the existing approach based on deterioration of physical ability, this will allow a new type of suggestion to enable the retirees to live their second lives in a more creative way. By analyzing their common memories and events, it was found that they developed their desire for leisure from their experience of wealth and economic growths. Some preceding research pointed out that their actual leisure activities tend to be static and passive in general. Through the interview, however, this research has found that there are 45 indoor activities and 75 outdoor leisure activities, while their potential demands for leisure further extends to 88. With outdoor activities outnumbering indoor activities, the result shows the opposite tendency to the preceding research. On the other hand, their potential demands for leisure further extended to include more intellectually stimulating learning activities.

The Implementation of Large-Scale Urban DevelopmentProjects in Brazilian Cities Case Study:Rio deJaneiro/RJ

The planning and implementation of large-scale urban development projects(UDPs)tend to arouse expectations of increasing investments to urban and social improvements.However,these urban interventions have been less democratic and more elite-driven priorities,resulting in socio-spatial segregation in the city.In the case of the Rio de Janeiro/RJ,the urban interventions planned for the years following the 2016 Olympic Games have not yet occurred in the totality.In this sense,it is necessary to understand the impacts of this mega-event’s intervention when the legacy does not attend the expectations of improvements in the city.Thus,the analyses took into account official documents and the perception of residents close to the areas that received interventions for the Olympic Games,regarding the changes that occurred in these places.It is evident the importance of discussing the subject to later outline guidelines or strategies that aim to minimise significant impacts generated by this insertion in the urban environment.

Suitability Evaluation of Physical Activity Places in Urban Parks for Children's Play Activities:A Case Study of Four Urban Parks in Handan

Taking 4 urban parks in Handan City as the research objects, 41 suitability evaluation indicators are selected according to the relevant literature reading. The common factors are extracted through factor analysis and the importance questionnaire and summarized into 6 dimensions, namely children's play facilities and auxiliary facility quality factor, natural environment participation factor, children's play space convenience factor, artificial environment participation factor, space environment quality and safety factor, children's game activity facility perfection factor, and the weights of public factors and indicators are calculated. Then the index score is calculated through field measurement and satisfaction survey, and the IPA analysis method is used to draw the coordinate map of key optimization indicators for 4 parks. Finally, corresponding optimization suggestions are put forward for Handan urban parks according to the analysis and evaluation results.

Physical activity among older Chinese adults living in urban and rural areas: A review

With an increase in rural-to-urban migration, a rapidly aging population, and the rising risk of developing noncommunicable diseases in China,it is important to understand the epidemiology of physical activity(PA) and health in the context of disease prevention and population health.Despite its public health importance, there is a significant lack of knowledge about PA in older Chinese adults that may hamper primary prevention efforts of health promotion in an increasingly aging population. To fill this gap, this article presents a narrative review of PA in the older Chinese adult population with a special focus on residential settings(i.e., urban and rural). Using existing studies, the review examines overall PA patterns and their correlates and discusses public health implications and future research. Although there are some preliminary indications of urban and rural differences in PA in the aging population in China, continued research efforts are needed to facilitate primary prevention efforts aimed at reducing noncommunicable diseases and promoting an active lifestyle among the largest population of older people in the world.

Spatial Characteristics and Influencing Factors of Urban Resilience from the Perspective of Daily Activity:A Case Study of Nanjing,China

Based on the connotation of urban resilience and the main contradictions of China's urbanization,urban resilience is placed within the main daily activities contradictory scene of the urban man-land system to build a theoretical framework of urban activity resilience.Relying on geographic big data,this study identifies the spatial characteristics of activity resilience,reveals the impact of activity environment on activity resilience in Nanjing,and proposes countermeasures.The main conclusions are as follows.1)Activity resilience presents a composite spatial structure of circles and clusters,and most areas are resilient but at a low level.2)There are significantly positive and negative global autocorrelation between activity resilience and activity scale,and activity stability.Simultaneously,there also exists a local spatial autocorrelation with the opposite positive and negative trends.3)Activity environment has a significant effect on activity resilience,and the degree and direction of influence among different dimensions and regions are heterogeneous.4)For activity resilience,it is necessary to increase the matching degree between the scale and stability of activities,and reduce the excessive concentration and flow of activities.For the activity environment,it is necessary to improve the accessibility of the ecological environment,strengthen the high-quality supply of the infrastructure environment,optimize the balance of the location environment,and promote the inclusiveness of the social environment.

A Preliminary Study on a Seismotectonic Model for the Active Faults in the Xining Urban Area

On the basis of the Xining active urban fault survey,we studied the relationship between the active urban fault and fold deformation.The result of this research shows that the Huangshuihe fault and the NW-striking fault on the northern bank of the Huangshuihe River are tensional faults on top of an anticline,the Nanchuanhe fault is a transverse tear fault resulting from differential folding on two sides of the fault,the east bank of the Beichuanhe River fault is a compressional fault developed on the core or climb of a syncline.By balance profile analysis of fold deformation and inversion of gravity anomaly data,we obtained the depth of the detachment plane and established the seismotectonic model of the Xining urban area.Based on the seismotectonic model,we analyzed the earthquake potential of the active urban fault.

Large Interactive Media Display and Its Influence on Transformation Urban Spaces from Neglecting to Action: The Case of Al-Thaqafa Street in Amman City

In 21st?century, media become the most important factor affecting the development of urban cities, including public places. As a result of the digital revolution, re-imaging and re-linkage public places by media are essential to create more interactions between public spaces and users, interaction media display, and urban screens, one of the most important defined media. This interaction can transform the urban space from being neglected to be more interactive space with users, specially the pedestrians. This paper aims to identify the effects of these new digital factors to transform public spaces, and the influences of large media display on the interaction between urban spaces and pedestrians. The paper focuses on Al-Thaqafa Street as one of the neglected spaces in Amman city, and attempts to analyse this street, explains its problems, and studies the influence of these new digital factors on its transformation, to be more active and vital by pedestrians.

Effect of physical activity on healthcare seeking behavior in the general Chinese population:an urban-rural perspective

Background:The“two-week visiting rate in those needing to visit”has been examined extensively as an important indicator of healthcare seeking behavior in China.Nevertheless,its relationship with health behaviors,such as physical activity,remains unknown.In addition,a significant difference exists between urban and rural Chinese people in terms of physical activity and healthcare seeking behavior.This study sought to investigate the relationship between physical activity and the two-week visiting rate by conducting a stratified analysis.Methods:The analysis included 5,801 participants aged above 15 years old.Multivariable logistic regression was applied to analyze the association after adjusting for possible confounding variables.Urban and rural differences were investigated using stratified analysis.Results:Adjusted estimates showed that those who were physically active were more likely to visit a healthcare facility,but only among the whole sample(adjusted odds ratio(AOR)=1.45,95%confidence interval(CI):1.26.1.66)and the rural sample(AOR=1.56,95%CI:1.21.2.01),and not among the urban sample.Conclusions:Educating people on physical activity may help in improving healthcare seeking behavior and vice versa.Additionally,health interventions may be tailored based on different settings.

Remarks on Urban Active Fault Exploration and Assessment of Fault Activity

According to the practice of urban active fault exploration and associated fault activity assessment conducted in recent years, this paper summarizes the problems encountered in geological, geomorphological, geochemical and geophysical surveys, and proposes the following means and suggestions to solve these problems. To determine the most recent faults or fault zones, emphasis should be placed on identifying the youngest active faults and offset geomorphology. To understand the history of faulting and to discover the latest offset event, it is suggested that geophysical prospecting, drilling and trenching be conducted on one profile. Because of significant uncertainties in late Quaternary dating, we advise systematic sampling and the use of multiple dating methods. Shallow seismic reflection has been proven to be the most useful method in urban active fault exploration. However, there is a pressing need to increase the quality of data acquisition and processing to obtain high resolution images so as to enhance our ability to identify active faults. The combination of seismic P-wave reflection and S-wave reflection methods is proved to be a powerful means to investigate the tectonic environments of the deep crust.

Study on Anti-Disturbance and High-Resolution Shallow Seismic Exploration of Active Faults in Urban Regions

The significance of detection of urban active faults and the general situation concerning detection of urban active faults in the world are briefly introduced. In a brief description of the basic principles of anti-disturbance and high-resolution shallow seismic exploration, the stress is put on the excitation of seismic sources, the performance of digital seismographs, receiving mode and conditions, geometry as well as data acquisition, processing and interpretation in the anti-disturbance and high-resolution shallow seismic exploration of urban active faults. The study indicates that a controlled seismic source with a linear or nonlinear frequency-conversion scanning function and the relevant seismographs must be used in data acquisition, as well as working methods for small group interval, small offset, multi-channel receiving, short-array and high-frequency detectors for receiving are used. Attention should be paid to the application of techniques for static correction of refraction, noise suppressing, high-precision analysis of velocity, wavelet compressing, zero-phasing of wavelet and pre-stacking migration to data processing and interpretation. Finally, some cases of anti-disturbance and high-resolution shallow seismic exploration of urban active faults are present in the paper.
