As an important part of urban construction,elderly-friendly construction is crucial to the formation of an elderly-friendly society,which has been widely recognized internationally.Especially after the COVID-19 pandemic,various organizations around the world have called for changes in public space and urban building planning,with an emphasis on the accessibility of green spaces.This underscores the complexity and difficulty of integrating vulnerable groups of the elderly into cities and using infrastructure and public space.

An Enhanced Multiview Transformer for Population Density Estimation Using Cellular Mobility Data in Smart City

This paper addresses the problem of predicting population density leveraging cellular station data.As wireless communication devices are commonly used,cellular station data has become integral for estimating population figures and studying their movement,thereby implying significant contributions to urban planning.However,existing research grapples with issues pertinent to preprocessing base station data and the modeling of population prediction.To address this,we propose methodologies for preprocessing cellular station data to eliminate any irregular or redundant data.The preprocessing reveals a distinct cyclical characteristic and high-frequency variation in population shift.Further,we devise a multi-view enhancement model grounded on the Transformer(MVformer),targeting the improvement of the accuracy of extended time-series population predictions.Comparative experiments,conducted on the above-mentioned population dataset using four alternate Transformer-based models,indicate that our proposedMVformer model enhances prediction accuracy by approximately 30%for both univariate and multivariate time-series prediction assignments.The performance of this model in tasks pertaining to population prediction exhibits commendable results.

Character and Causes of Population Distribution in Shenyang City,China

Character of population distribution is one of the focuses studied by urban geography. Using the fifth national census data as basic data and using areal interpolation method, this paper analyzes character of urban population dis- tribution of Shenyang City, Northeast China, in terms of three aspects of statistical character, spatial auto-correlation and spatial structure. Furthermore, this research analyzes the factors affecting the population distribution of the city. The main conclusions include: 1) There is an obvious structure character of population distribution in the grid with a grain of 300m, which is appropriate scale when researching population distribution in Shenyang City. 2) Urban population dis- tribution has the character of assembling while population density distribution takes on variability in Shenyang City. 3) Population density distribution shows spatial auto-correlation within 7.36km. Spatial heterogeneity of population density is low. 4) Urban center, population distribution barycenter and population density maximum points separate each other. Population density distribution has multi-cores character. 5) Layout of governments, primary schools, middle schools, colleges, hospitals and marketplaces affects population distribution directly. With the increase of distance to these factors, population density decreases as logarithm.

Simulation Analysis on Spatial Pattern of Urban Population in Shenyang City,China in Late 20th Century

The spatial distribution of urban population can reflect significantly urban functions and development status. Shenyang, as a typical old industrial city in China, has experienced considerable changes in spatial distribution of population in the process of urban transformation, resulting in the change of urban spatial structure. Based on the sub-district data of Chinese national population censuses in 1982, 1990 and 2000, this study simulates the evolution pattern of spatial distribution of urban population in Shenyang City. Using statistical method and exploratory spatial data analysis (ESDA), we found that the population distribution, on the whole, has presented a balanced and decentralized trend since the 1980s, which characterizes with Chinese suburbanization. Furthermore, based on the investigation of the pattern of population distribution, it is concluded that the negative exponential model fitted the distribution best, and population concentration in the inner suburb kept increasing gradually, meanwhile, the spatial structure of population distribution has presented a polycentric feature since the 1980s. The parameters of the model show that population in the urban core concentrate significantly all the time. The increase of population in the inner suburb influences the population distribution pattern more and more importantly, but the concentration intensity of population cores in inner suburb is still low.

Ecological Optimum Population of Binzhou City Based on PEER Model

Taking into account the regional carrying capacity,the population capacity and optimum population of Binzhou City from 2007 to 2017 under certain economic,resource and environmental conditions were calculated based on PEER model.The results show that the population capacity of Binzhou City during 2007-2017 ranged from 6.03 million to 6.43 million,and ecological optimum population was between 5.05 million and 5.34 million.The actual population of the city was between 3.74 million and 3.94 million.The impact of the "two-child" policy on population growth was small,and there was still room for population growth.The population pressure index was greater than 0.7 and less than 1,showing that economic and resource population carrying capacity had certain surplus but were still not optimistic.Environmental pressure index was relatively high,and population carrying capacity was low.

The Population Carrying Capacity of Water Resources in Yulin City

Assessing the water resource carrying capacity is beneficial for measuring the scale of industry and population agglomeration,and also avoiding the contradiction between increasing people and decreasing available water resource,due to the expansion of industry and city size.Based on the prediction model of optimum population development size,by using hydrological data,also with the demographic data from 1956 to 2010,this article analyzes and predicts the urban moderate scale under the limit of the water resource in the future of Yulin City by GIS. The main conclusions are as follows. There is growing tendency of water resources overloading. According to the result of model simulation,by2015,the overload rate of population size will be 1. 04. By 2020,the overload rate of population size will grow up to 1. 08. The oversized population mainly comes from cities and towns. The overload rate for cities and towns in 2015 and 2020 is 1. 89 and 1. 73,respectively. With the expansion of cities and industries,suburban areas could have a great potential for carrying population,because lots of suburban people may move to cities and towns according to prediction. In view of the above-mentioned facts,the population size should be controlled in a reasonable range.

Land Potential Productivity and Population Carrying Capacity of Yan'an City

The productivity attenuation method is adopted to calculate land potential productivity of counties of Yan'an City and calculate population carrying capacity at current productivity level. Result shows that high photosynthetic potential productivity area and high light and temperature potential productivity area are mainly situated in the north,while high climatic potential area and high land potential productivity area are mainly concentrated in the south. From solar radiation,moisture and landform,the attenuation amplitude of land potential productivity in northern counties ( districts) is greater than that in southern counties ( districts) . In the whole city,the population carrying capacity of 9 counties reaches well-off living level,and 1 district still does not reach the level of adequate food and clothing. These results can provide reference for land resource use,agricultural production distribution and population growth control.

The public health benefits of Tai Ji Quan——Addressing the unmet needs of aging populations in the 21st century

1.Introduction With the increase in older populations worldwide1 comes an increased health burden related to chronic diseases.2–4One of the most disabling of these is knee osteoarthritis（OA）,which occurs in millions of older adults who subsequently live with joint pain and stiffness,leading to chronic disability and a diminished quality of life.5,6 Epidemiological evidence shows a higher prevalence of OA in older adults living in urban and

Origin Distribution Patterns and Floating Population Modeling:Yiwu City as a Destination

Existing quantitative migration studies are mainly at the inter-region or inter-province level for lacking of detailed geo-referenced migration data.Meanwhile,few of them integrate explorative spatial data analysis and spatial regression model into migration analysis.Based on aggregated registered floating population data from 2005 to 2008,the phenomena that population floating to Yiwu City in Zhejiang Province is analyzed at the provincial and county levels.The spatial layout of Yiwu's pull forces is proved as a V-shaped pattern excluding Sichuan Province based on map visualization method.Using the migration ratio in 2007 as an explanatory variable,two models are compared using ordinary least square,spatial error model and spatial lag model methods for county-level data in Jiangxi and Anhui provinces.The model with migration stock provides an improved fitting over the model without migration stock according to the model fitting results.The floating population flocking into Yiwu City from Jiangxi is determined mostly by migration stock while the determinant factors are migration stock and distance to Yiwu City for Anhui.The distance-decay effect is true for migration flow from Anhui to Yiwu City while the distance rule is not confirmed in Jiangxi with the best fitting model.The correlation between per capita net income of rural labor forces and migration ratio is not significant in Jiangxi and significant but at the 0.1 level only in Anhui.Further analysis shows that the distance,income and man-land ratio are important factors to explain population floating at earlier stage.However,as the dynamic population floating process evolves,the determinant factor would be migration stock.

THE RECENT ECONOMIC DEVELOPMENT OF CHINA'S 'MILLION' CITIES

Since the 1980's, two new trends have been emerging in the economic development of the Chinese ' million'cities.One is the development disparity, and the other is the industrial restructuring.Firstly,in terms of per capita GDP(Gross Domestic Product), 32 'million' cities are classified into 4 types.The paper thinks there are 3 main causes which bring about the development disparity.Then, the paper approaches the industrial restructuring of the 'million'cities. In order to shrink the gap between the coastal 'million' cities and the interior 'million' cities, the paper thinks that the central government should pay most attention to the economic development of the inland, meanwhile,the interior 'mllion' cities should speed up the economic reform and industrial restructuring.

China′s Urban Population Numbers 515 million

By the end of 1996,there were 666 institutional cities with an urban populationof 515.11 million,making up 42.Y of the national popula tion,according to data from the State Sta-tistical Bureau.Of the 515.11 million urban population,207.79 million were non-agricultural population.

ECG is not a reliable predictor of sudden cardiac death in the general population

Objectives: To determine the predictive value of the ECG for sudden death in the general population. Design: In the Copenhagen City Heart Study, a randomly selected population sample in Copenhagen, Denmarkhas been followed prospectively since 1976. From this population sample, we analyzed ECGs of individuals who had suffered sudden cardiac death (SCD) before the age of 50 years and compared them with ECGs of a randomly selected control individuals from the same population sample. Specific ECG signs that could point toward a condition associated with a risk of SCD were noted. Results: From a total of 18,974 individuals in the cohort, 207 had died at an age younger than 50 years. Among these, 24 persons with SCD were identified. The most prevalent ECG abnormality was QRS fragmentation. We found no ECGs with long or short QTc, Brugada sign or WPW. The prevalence of signs of left ventricular hyper-trophy, early repolarization, or fragmentation was not different from the prevalence of these signs in the control group. Conclusion: In the Copenhagen City Heart Study, the ECG failed to predict SCD in persons who died before the age of 50 years.

Study on Urban Hierarchy Status of Sports Population in Jiangxi Province

The survey shows that urban sports population in Jiangxi Province have the following characteristics： the ＂jobless or unemployed＂ , ＂retired＂ vastly outnumber office workers, which reflects the uneven distribution of various strata; men outnumber women among the young and mid-aged and women are slightly outnumber men among the elderly, which reflects the uneven gender distribution; sports participation investment of higher income strata is relatively high, and low-income people are taking universal sports activities. To optimize the structure of sports population, the government needs to increase public investment in sports venues and facilities and publicity of the national fitness program, using legislation to protect off work time and raising the minimum income standards, and urging enterprises to set staff room, sports venues and facilities.

The “Floating Population” in Lhasa City

Lhasa,to some extent,is regarded as a holiday city.It is hard to meet people when they are in a rush. Whenever a pilgrimage procession passes by,you can always see the pilgrims holding their praying wheels, followed by dogs,while they walk peacefully along the path of the pilgrimage.On the edges of streets and laneways,tea bars are teeming with people playing cards or chatting.Once they sit down,they might easily let half a day slip by.

Population Shrinkage in Resource-dependent Cities in China: Processes, Patterns and Drivers

Resource-dependent cities(RCs)are a vulnerable group of urban settlements that often face population shrinkage;however,population changes in RCs in China are not well understood.This study offers new insight into this matter through a robust analysis that features a longer time scale,a larger sample of RCs,and a finer unit of analysis.It finds new evidence that problems of population shrinkage in RCs are more serious than previous literature has suggested.Approximately 30%of the studied units have experienced either long-term or short-term population shrinkage,and many more are experiencing a slowing down of population growth.Problems are especially common among three types of RCs:the resource-depleted RCs,the forestry-based RCs,and RCs in Northeast China.These results underscore transition policy inadequacies in addressing population loss,and call for a more comprehensive and diversified population policy that tackles the multifaceted factors that contribute to population shrinkage,including lack of industrial support,maladjustment to market oriented reformation,poor urban environment and natural population decline.

ON THE SUBURBANIZATION OF BEIJING

Suburbanization is a stage of urbanization provess. The author discesses the situation of Beijing from the data of three population censuses(1964, 1982, 1990) and considers that the suburbanization in Beijing has been in process since 1982. During 1982-1990, population of all districts of the inner city lost 82 000 persons and in fact the permanent residents holding the household registration lost 144 000, which is about 6. 12% of permanent residents in the inner city.Like the West, suburbanization in China the happened against the macro backgrounds of improvements of transportation and loving conditions, growth of urban population moving from rural areas. But in the case of the forces that make decentralization possible, China is different from the western countries. In China, the levels of economy and urbanization are rather low, the red middle class is not rich; only very few Chinese families families provate cars, and the inner cities still have great attraction to Chinese people. The author considers three causes of decentralization: (1) reform of urban land use system brings about migration from the core area; (2) construction of a large number of city roads reinforces this process; (3) reforms of housing system and renovation of dilapidated houses encourage outward movement. However, the process wasn’t of spontaneity of any individual but of the leadership of government and “Dan Wei” (Work Unit).
