At present, the planning of 15-minute community-life circle is being actively promoted in China. Taking Baoding City as an example, the status quo of service facilities layout was analyzed based on the POI data. Using the spatial accessibility algorithm, the ranges of 15-minute life circle of more than 1000 communities in Baoding were determined. By calculating the up-to-standard rates of public service facilities in each district, it is found that the allocation of medical facilities and commercial facilities in urban community life circle is relatively perfect, but the allocation of public cultural facilities and pension facilities is obviously inadequate. Based on this, optimization suggestions on the layout of public service facilities in the 15-minute life circle were put forward from three aspects: facilities sharing, function mixing and population structure and activity characteristics differentiation. It not only provides data and technical support for the planning and construction of community life circle in Baoding city, but also provides referable examples and promotable models for the community planning of third-tier cities. 展开更多

Delineating life circles is an essential prerequisite for urban community life circle planning. Recent studies combined the environmental contexts with residents’ global positioning system(GPS) data to delineate the life circles. This method, however, is constrained by GPS data, and it can only be applied in the GPS surveyed communities. To address this limitation, this study developed a generalizable delineation method without the constraint of behavioral data. According to previous research, the community life circle consists of the walking-accessible range and internal structure. The core task to develop the generalizable method was to estimate the spatiotemporal behavioral demand for each plot of land to acquire the internal structure of the life circle, as the range can be delineated primarily based on environmental data. Therefore, behavioral demand estimation models were established through logistic regression and machine learning techniques, including decision trees and ensemble learning. The model with the lowest error rate was chosen as the final estimation model for each type of land. Finally, we used a community without GPS data as an example to demonstrate the effectiveness of the estimation models and delineation method. This article extends the existing literature by introducing spatiotemporal behavioral demand estimation models, which learn the relationships between environmental contexts, population composition and the existing delineated results based on GPS data to delineate the internal structure of the community life circle without employing behavioral data. Furthermore, the proposed method and delineation results also contributes to facilities adjustments and location selections in life circle planning, people-oriented transformation in urban planning, and activity space estimation of the population in evaluating and improving the urban policies. 展开更多

Population aging has developed into a significant area of concern in developed countries, especially in relation to thepreservation of functional independence and the quality of life (QoL). However, information on the contribution ofsex differences in quality of life and cognitive function is scarce. Therefore, this study aimed to investigate potentialdifferences in cognitive function and QoL between males and females. For this study, we recruited 382 healthy subjectsaged 19–79 years from communities in Southern Taiwan region,China. Cognitive function and QoL were assessed using the UCSD Performance-based Skills Assessment, Brief Version (UPSA-B) and World Health Organization Quality ofLife Instruments (WHOQOL-BREF), respectively. The effects of sex, age groups, and interaction of sex and ageon the UPSA-B and WHOQOL-BREF scores were examined. We found that the financial and communicationdomains of the UPSA-B showed declining trends with age in both sexes, although these trends were more obviousin females than in males. In the domain of Physical Capacity, QoL showed an age-increased trend in males, whileQoL in the Environment domain showed an age-increased trend in females. Regarding the relationships betweencognitive function and QoL, we found that the financial skill and communication skill of UPSA-B was positivelycorrelated to the psychological well-being domain of WHOQOL-BREF, in males of age <40 years. In conclusion,our findings demonstrate differential relationships between cognitive function and QoL between males and females,which could serve as a basis for further study between cognitive function and quality of life in communities. 展开更多

Quality of life (QOL) is an important topic in social and medical sciences, it has a multidimensional nature and is influenced by many factors. Aim of the Work: In this study we want to assess the impact of cognitive impairment on the health related quality of life (HR-QOL) of community dwelling non demented elderly. Subject and Method: 115 non demented elderly, 60 years and older recruited from outpatient geriatric clinic at Al Mansoura General Hospital, Dakahlia, Egypt. Each participant underwent, comprehensive geriatric assessment, assessing cognitive function using the mini-mental state examination (MMSE) and montreal cognitive function test, assessing the health related quality of life (HR-QOL) by the RAND-36 health survey. Results: We found that the elderly with impaired cognition by both MMSE and Montreal test were significantly older;the ones with lower education, with more depressive symptoms, had more functional impairment and had lower HR-QOL scores than the elderly with normal cognitive function, after controlling for confounders still cognition was a determinant of HR-QOL. Also by linear correlation coefficient a significant correlation between HR-QOL and age, function, cognition and depression was found. Conclusion: Cognition affects significantly HR-QOL of the elderly, so we can say that interventions targeting cognition in the elderly can significantly improve their QOL. 展开更多

As Chinese cities undergo a transition from incremental development to retrofit development and urban governance tends to be more refined, the renovation mode of old residential communities is also under the transformation from large-scale bulldozer demolition and reconstruction to small-scale refined renovation and regeneration. However, the practice of micro community renovation has encountered a number of challenges throughout the implementation process, including conflicts between multiple stakeholders in the initial stage of planning, unconcordance between different implementation bodies in the intermediate stage of construction, and the lack of guarantee mechanisms in the later stage of maintenance.Based on the concept of life cycle, this paper divides the practical process of micro community renovation into seven steps, i.e., establishing communal platforms, identifying community features, cultivating communal organizations, designing community activities, formulating planning schemes,conducting participatory constructions, and establishing long-lasting mechanisms. It takes the Gejiaying Community in Wuhan as a case to verify the above analysis, in the hope of providing a reference for the current practice of urban regeneration and community renovation in China. 展开更多

It is projected that aged population (≥60 years) will continue to increase globally, including in Africa. This is due to reduced population growth, decreased fecundity and improved medical interventions;factors which increase life expectancy. While this is typical for developed countries, it is not the same for Africa and similar developing regions. In these regions, a significant proportion of death is due to non-communicable diseases (NCD’s) such as hypertension, cerebrovascular accident, coronary heart disease, diabetes mellitus, chronic renal disease and cancer, among others. Rising prevalence of NCD’s due mainly to western style diets and sedentary living is made worse by inadequate nutrition education, high prevalence of low birth weight, poor health services, lack of efficient tobacco control and deficient planning of built environment. In order to halt the possible reduction in life expectancy occasioned by NCD’s, efforts by the community, health planners and governments in Africa to address relevant NCD’s, must be put in place. Suggested measures are: nutrition education, regular community directed physical exercise, improved environmental planning and development. Others are review of present health service model, early detection, prevention and treatment of NCD’s, including improved antenatal care to reduce low birth weights, and establishment of policies and measures that decreased access to tobacco especially by women of childbearing age. Africa and similar developing regions cannot fund the health bill due to NCD’s and their complications;hence it is important that this scourge is attended to with all seriousness. 展开更多

According to the report to the 19th CPC National Congress, socialism with Chinese characteristics entered a new era with the specified strategical task of building China into a great modern socialist country that is prosperous, strong, democratic, culturally advanced, harmonious and beautiful. The report also stressed that building an ecological civilization is vital to sustaining the Chinese nation's development. Against such a backdrop, it is necessary to analyze the "building of an ecological civilization" from three directions, i.e. satisfying people's requirement for a better life, fulfilling the goal of the Beautiful China Initiative and taking the lead in global ecological governance. This is an inevitable requirement for the advancement of the harmonious coexistence between man and nature and at the same time corresponds to the internal demand for the implementation of Xi Jinping Thought on Socialism with Chinese Characteristics for a New Era. 展开更多

Background: Despite a high prevalence of hearing impairment (HI) among the elderly, the effect on their quality of life (QOL) has not been well studied in this environment. Aim: To determine the prevalence of disability and profile of QOL among elderly persons (aged ≥65 years) with HI. Design of Study: Cross-sectional. Setting: Eight contiguousYoruba-speaking states in Nigeria. Methods: Face-to-face interviews of respondents selected using a multi-stage, stratified area probability sampling of households;HI was based on self report and observer confirmation and the QOL was measured with the World Health Organization brief version (WHOQOL-Bref). Results: The prevalence of disability in Activities of Daily Living (ADL) was 35.4% while it was 10.1% in Instrumental ADL. Prevalence increased significantly with increasing age (P = 0.05). Disability in ADL (P = 0.01), poor family interaction (P = 0.01), poor community involvement (P = 0.01) cognitive impairment (P = 0.05) and poor report of overall health (P = 0.05) were significantly more common among the elderly with HI than those without. No significant differences were found in regard to current depression or the likelihood of experiencing verbal, physical or emotional abuses. Logistic regression analyses adjusting for age, sex, chronic medical conditions and disability confirmed the salient effect of HI on the decrement in the physical domains (P = 0.05). Conclusion: HI is associated with high prevalence of disability and has adverse effect on the quality of life. This observation strengthens the need for hearing rehabilitation in the policy formulation on the care of the elderly in resource-poor settings. 展开更多

To investigatetheinfluences of the application of human care theory on the life quality and happiness of cancer patients after they receiveda community nursing care which was implemented by the human care theory. The quality life and the happiness index of 93 patients with cancer living in the six communities in Jillin were assessed, the assessment of the life quality was based on a life quality scale (SF-36) and that of the happiness index was based on Memorial University of Newfoundland Scale of Happiness (MUNSH). The community nurses cared for these patients by applying the theory of human care and the life quality and the happiness index of the patients were observed after the care. The results showed that there were significant differences in the score of 5 dimensions in the eight dimensions of the life quality between before the care and after the care (<0.05), and there were significant differences in the average sores of the positive emotion, positive experience, negative emotion, negative experience and level of happiness included in the happiness index between before the care and after the care (<0.05), suggesting that the theory of human care can be used for the care of patients with cancer and the application of the theory can effectively improve the life quality and the happiness index of the patients, strengthen their problem-solving abilities and let them have a positive attitude towards their lives. 展开更多

Phyllosphere microorganisms are a crucial component of environmental microorganisms,highly influenced by host characteristics,and play a significant role in plant health and productivity.Nonetheless,the impact of host characteristics on shaping phyllosphere microbial communities of plants with different life forms remains ambiguous.Utilizing high-throughput sequencing technology,this study analyzed the diversity and community composition of phyllosphere epiphytic microorganisms(e.g.,bacteria and fungi)of various plant life forms in the hinterland of the Gurbantunggut Desert,Northwest China.Functional annotation of prokaryotic taxa(FAPROTAX)and fungi function guild(FUNGuild)were employed to assess the ecological functions of microorganisms and to investigate the role of stochastic and deterministic processes in shaping phyllosphere microbial communities.Result showed a diverse array of phyllosphere epiphytic microorganisms in the desert plants,with Proteobacteria,Cyanobacteria,and Actinobacteriota dominating bacterial community,while Ascomycota and Basidiomycota were prevalent in fungal community.Comparison across different plant life forms highlighted distinct microbial communities,indicating strong filtering effects by plant characteristics.FAPROTAX prediction identified intracellular parasites(accounting for 27.44%of bacterial community abundance),chemoheterotrophy(10.12%),and phototrophy(17.41%)as the main functions of epiphytic bacteria on leaves of different life form plants.FUNGuild prediction indicated that phyllosphere epiphytic fungi primarily served as Saprotrophs(81.77%),Pathotrophs(17.41%),and Symbiotrophs(0.82%).Co-occurrence network analysis demonstrated a predominance of positive correlations among different microbial taxa.Raup-Crick dissimilarity index analysis revealed that deterministic processes predominantly influenced phyllosphere bacterial and fungal community assembly.Variance partitioning analysis and random forest modeling suggested that plant leaf functional traits significantly impacted both bacterial and fungal community composition,with fungal community composition showing a closer association with leaf nutrients and physiology compared with bacterial community composition.The distinct responses of bacterial and fungal communities to plant traits were attributed to the differing properties of bacteria and fungi,such as bacteria having higher potential dispersal rates and broader ecological niches than fungi.Overall,the results indicate that phyllosphere bacterial and fungal communities undergo similar community assembly processes,with fungi being more influenced by plant characteristics than bacteria.These findings offer novel insights into the ecology of phyllosphere microbial communities of desert plants. 展开更多

This study explores the role of Bedouins in preserving Palestinian land through their own means of community resilience through the concept of“Art of being”and its entailed“Arts of presence and persistence”.This is examined through the correlation between Bedouin lifestyle and the spatial distribution of structures within“Al-Kurshan”Bedouin clan in Area C in the West Bank.Based on a mixed qualitative and spatial methodologies,information was gathered through semi-structured interviews with Al-Kurshan Bedouins and employees of organizations supporting Bedouins,on-site observation,and analyses of maps and photos,in addition to drawings and illustrations.The spatial distribution of Bedouin built structures is analyzed in relation to landscape and climate,social aspects within the families,and available service and sectorial infrastructures.These analyses give insight on how Bedouins struggle against adopting other lifestyles.The study shows that the Bedouins are slowly forced to negotiate their semi-nomadic lifestyle,but resist giving up their right to exist against the threat of forced displacement.They maintain their“Art of being”which partly represents their own way of safeguarding Palestinian lands from confiscation.The study contributes to the wider discussion of spatial dynamics of Bedouins and their community resilience within the Palestinian geopolitical context. 展开更多

A phytosociological study of a weed community dominated by Hydrocotyle mannii and Centella asiatica was carried out in Kampala, the capital city of Uganda from 2000 to 2002. The Zurich-Montpellier School of Phytosociology method was used with special emphasis on floristic and synecological structure as well as on dynamic aspects. This community was found to grow on shady moist roadsides and is about 15 cm high. In total, 54 species were recorded; most of them are annual, anemochorous and widespread. The Hydrocotyle mannii and Centella asiatica community is described as a new weed association: Hydocotylo-Centelletum asiaticae Mosango ass. nova.. Hydrocotyle mannii, Centella asiatica, Dichondra repens and Sida veronicifolia have been recognized as the character species of this association. The Hydrocotylo-Centelletum is a pioneer association. It has been ascribed to the alliance Eleusinion indicae Leonard 1950 which includes plant communities growing on shady roadsides. In terms of ecological succession, it appears to be evolving to the Asystasia gangetica herbaceous fallow association which belongs to the alliance Panicion maximi. It belongs to the order Ruderali-Euphorbietalia Schmitz 1971 and the class Ruderali-Manihotetea Leonard in Taton 1949. 展开更多

Background Apolygus lucorum is a worldwide omnivorous pest damaging a range of crops and causing great economic losses.Symbiotic bacteria living in insects play a key role in the nutrition,physiology,and behavior of hosts.Here,we present an experiment using Illumina HiSeq sequencing targeting the V3–V4 regions of bacteria’s 16S rRNA throughout the entire life cycle of A.lucorum.Results The first and second instar nymphs have the largest alpha diversity compared with other life stages of the insect.Bacterial phyla Proteobacteria(72.29%),Firmicutes(15.24%),Actinobacteria(7.76%)exhibit the largest relative abundance in all developmental stages.Erwinia(23.97%)and Lactococcus(10.62%)are the two genera with the high-est relative abundance.The relative abundance of Erwinia in the nymph stage is significantly greater than the adult stage,and the relative abundance of Lactococcus in 6-day-old and 9-day-old adult females is higher compared with adult males.Conclusions These results reveal that microbial community composition and relative abundance shift dynamically at different life stages,implying that different bacterial phyla and genera may have specific roles in specific life stages such as metabolism,nutrition absorption,detoxification,and reproduction.This study reveals for the first time the community composition and ecological dynamics of symbiotic bacteria throughout the life stages of A.lucorum,and thus may provide insight to new strategies for pest control. 展开更多
