Destinos e distâncias da caminhada recreativa e utilitária: estudo empírico na cidade de Londrina-Paraná / Destinations and distances of recreational and utilitarian walking: empirical study in the city of Londrina-Paraná

Pesquisas indicam correlatos ambientais distintos para caminhada utilitária e recreativa. Este estudo teve como objetivo identificar locais, destinos e distância percorrida em caminhadas recreativas e uti-litárias, e comparar espacialmente a percepção sobre os locais caminhados. Para isso, foi realizado um estudo observacional transversal, conduzido em Londrina, Brasil. Os dados foram coletados através de questionário aplicado na plataforma Survey123, que contemplou pessoas maiores de 18 anos que reportassem ao menos uma rota de caminhada realizada no município de Londrina. A análise dos deslocamentos reportados foi feita pela estimativa de densidade de Kernele as distâncias de cami-nhada foram analisadas através do coeficiente de correlação ponto-bisserial ­ rpb. A espacialização dos dados perceptivos, obtidos através do questionário Neighborhood Environment Walkability Scale­ NEWS, foi realizada pela identificação de agrupamentos significativos através do indicador Gi*. A amostra totalizou 182 participantes e 305 deslocamentos a pé, dos quais, 61 classificados como ca-minhada recreativa e 244 como utilitária. Os locais de maior densidade de deslocamentos recreativos possuem ampla infraestrutura para pedestres, enquanto os de concentração de deslocamentos utili-tários são caracterizados pela diversidade de uso do solo. A caminhada recreativa registrou distância média de 3.955,3 ± 2.503,5m sendo que, para a caminhada utilitária, a média foi 1.247,0 ± 1.034,0m. A correlação ponto-bisserial obteve rpb = 0,611 e p<0,001, moderada a forte, indicando correlação po-sitiva entre a realização de viagens recreativas e uma maior distância média de caminhada. A pesquisa contribui para a investigação do comportamento de caminhada pela associação de variáveis objetivas e subjetivas e pela captura dos trajetos de deslocamento a pé.

Studies indicate distinct environmental correlates for utilitarian and recreational walking. This study aimed to identify the locations, destinations and the distance traveled in recreational and utilitarian walks, and to compare spatially the perception about the walked places. To achieve this, a cross-sectional observational study was conducted in Londrina, Brazil. Data was collected through a questionnaire applied on the Survey123 platform, including people aged 18 or over that reported at least one walking route performed in Londrina. The route analysis was made by Kernel density estimation and walking distances were analyzed through the point-bisserial correlation coefficient - rpb. The spatialization of perception data, obtained through the Neighborhood Environment Walkability Scale - NEWS form, was performed by identifying significant clus-ters through the Gi* indicator. The sample totaled 182 participants who reported 305 walk routes, of which 61 were classified as recreational walking and 244 as utilitarian. The places of higher recreational walking density have ample infrastructure for pedestrians, and the places with utilitarian walking concentration are characterized by the diversity of land use. Recreational walking recorded mean distance of 3.955.3 ± 2.503.5m, and for utilitarian walking, the average was 1.247.0 ± 1.034.0m. The point-bisserial correlation obtained rpb = 0.611 and p<0.001, moderate to strong, indicating a positive correlation between recreational trips and a greater average walking distance. This research contributes to the investigation of walking behav-ior through the association of objective and subjective variables and through the capture of walking routes.

A cidade não pode parar: a Maratona do Rio de Janeiro em 2020 na era da pandemia / The city cannot stop: the Rio de Janeiro Marathon in the era of the pandemic / La ville ne peut pas s'arrêter: le Marathon de Rio de Janeiro à l'ère de la pandémie

Neste artigo, iremos apresentar como ocorreu a edição virtual da Maratona do Rio de Janeiro em 2020, ainda sem autorizações sanitárias para a realização de grandes eventos. Para isso, analisaremos o Guia do corredor, apresentado aos corredores na época. A competição é realizada por meio de uso de aplicativos, mas o atleta é estimulado a correr com o slogan "Não correr nunca foi uma opção". Abordamos os conceitos de necrodemografia e necropolítica. Entende-se que a Maratona do Rio pratica uma espécie de necropolíti-ca ao organizar a competição em pleno período pandêmico do Brasil, apesar de valorizar a paisagem da rua em suas plataformas comunicacionais.

In this article, we will present how the virtual edition of the Rio de Janeiro Marathon took place in 2020 in the middle of the pandemic, still without health permits to hold major events. For this, we will analyze the Runner's Guide presented to the runners at the time. The competition is carried out using applications, but the athlete is encouraged to run with the slogan "Not running was never an option". We approach the concepts of necrodemography and necropolitics. It is understood that the Rio Marathon practices a kind of necropolitics when organizing the competition in the middle of the pandemic period in Brazil, despite valuing the street landscape in its communication platforms.

Dans cet article, nous allons vous présenter comment s'est déroulée l'édition virtuelle du Marathon de Rio de Janeiro en 2020, toujours sans autorisations sanitaires pour les grands événements. Pour cela, nous analyserons le Guide du marathonien, présenté aux marathoniens à l'époque. La compétition se déroule à l'aide d'applications, mais l'athlète est encouragé à courir avec le slogan "Ne pas courir n'a jamais été une option". Nous abordons les concepts de nécrodémographie et de nécropolitique. Il est entendu que le Marathon de Rio pratique une sorte de nécropolitique en organisant la compétition en pleine pandémie au Brésil, malgré la valorisation du paysage de rue dans ses plateformes de communication.

Os jovens e suas práticas de lazer: um olhar diante os decretos da PBH / Young people and their leisure practices: a look at the PBH Decree

O vírus da Covid-19 afetou de diversas formas a população mundial e, com isso, surgiu a necessidade da implementação de medidas sanitárias para evitar sua propagação. Em Belo Horizonte, essas medidas vieram por meio de decretos municipais, que proibiram o funcionamento de serviços considerados não essenciais. A partir desse momento, os jovens acostumados a frequentar bares, festas, shoppings ­ lugares que geram intensa aglomeração ­ se depararam com uma situação inusitada, sendo obrigados a adaptarem suas práticas à rotina do lar. Com o intuito de compreender melhor essas mudanças, realizamos um estudo que analisa os impactos da pandemia nas práticas de lazer desses jovens. Por meio de um questionário aplicado em diversos pontos de lazer da cidade, conseguimos observar como as práticas de lazer dos jovens foram afetadas pela pandemia. Esses resultados enfatizam a importância da adaptabilidade e resiliência dos jovens diante novos desafios.

The Covid-19 virus has affected the global population in various ways, leading to the need for the implementation of sanitary measures to prevent its spread. In Belo Horizonte, these measures came through municipal decrees, which banned the operation of non-essential services. From that moment on, young people accustomed to frequenting bars, parties, and malls ­ places that generate intense crowding ­ found themselves in an unusual situation, being forced to adapt their practices to home life. In order to better understand these changes, we conducted a study analyzing the impacts of the pandemic on the leisure practices of these young people. Through a questionnaire applied at various leisure points in the city, we were able to observe how the leisure practices of young people were affected by the pandemic. These results emphasize the importance of adaptability and resilience of young people in face of new challenges.

Investigation of Anisakis infections in coastal marine fishes and awareness of anisakiasis control knowledge among residents in Yantai City in 2021 / 中国血吸虫病防治杂志

Objective To investigate the prevalence of Anisakis infections in coastal marine fishes and awareness of anisakiasis control knowledge among local residents in Yantai City, Shandong Province in 2021, so as to provide insights into formulation of anisakiasis control interventions. Methods Marine fishes were purchased from Shunxin Port, Yantai City, Shandong Province in November 2021, and the presence of Anisakis was detected in different species of fishes and different fish sites. The correlations between body length and weight of marine fish and intensity of Anisakis infections were examined using Spearman’s rank correlation analysis, and the dietary habits and anisakiasis control knowledge were investigated using questionnaire surveys among local residents. Results A total of 201 marine fishes belonging to 20 species were dissected, and Anisakis was detected in 77 marine fishes (38.31%) belonging to 11 species (55.00%), with a mean infection intensity of 45.04 parasites per fish (3 468/77). Spearman’s rank correlation analysis revealed that the body length (rs = 0.74, P < 0.05) and weight (rs = 0.79, P < 0.01) of the monkfish correlated positively with the intensity of Anisakis infections, and the body length (rs = 0.68, P < 0.05) of the flatfish correlated positively with the intensity of Anisakis infections, while no correlations were examined between the body length or weight of other marine fishes and the intensity of Anisakis infections. Of all respondents, 53.38% men and 56.67% women did not know anisakiasis control knowledge at all, and there was a significant difference in the proportion of respondents using separate chopping boards for raw and cooked food from different villages (χ2 = 17.89, P < 0.01), while there was an age-specific proportion of respondents with habitats of eating raw or semi-raw seafood (χ2 = 28.27, P < 0.01). Conclusions The prevalence and intensity of Anisakis infections were high in coastal marine fishes in Yantai City in 2021, and the awareness of anisakiasis control knowledge was low among local residents. Intensified health education pertaining to anisakiasis control knowledge is recommended to reduce the risk of Anisakis infections.

Sustainability can be defined as the practice of reserving resources for future generation without any harm to the nature and other components. In the recent years, Haryana has seen a natural progression in its development story. As the big villages turning into towns, and towns transforming into cities. But it's the time for the state to transform its cities into smart and sustainable cities for the smart urbanization. Though urbanization brings a lot of challenges that can act as a barrier to growth of urbanization or the smart cities. The people move to urban centers in such of jobs and employments and hopefully the better life. Urbanization is change of residence which is geographically expressed as mobility or migration resulted by a way of life called urbanism. It is the proven fact, that the trend has a straight correlation with growth.

De la caracterización de la población moradora al acompañamiento en la construcción de experiencias de resistencia al despojo, en la conflictividad urbana de la ciudad de Medellín

Se sistematizan algunas iniciativas y experiencias de organización comunitaria, en proceso de construcción de territorialidad como lo son las de los participantes de la "población moradora", inmersa en los escenarios del despojo, provocado por las alianzas público-privadas del urbanismo neoliberal en el Valle de Aburrá, que al lograr convertirse en sujetos organizativos consolidan apuestas por el trabajo colectivo de transformación social. La reflexión en modo IAP da cuenta de la forma como en medio de las adversas problemáticas de su mundo de la vida, por medio del trabajo con herramientas formativas, la "población moradora" se constituye como subjetividad erguida y de resistencia, en permanente construcción de un proyecto de incidencia política.

In the midst of the advance of the urban intervention of the alliances between the officialdom and the financial guilds for the benefit of the private sector, which took place in the first two decades of the 21st century in the city of Medellín, some considerations are made on the contextual conditions in which the phenomenon of resistance of the population named dweller in the city of Medellín and the metropolitan area emerges. Thus, some initiatives and experiences of community organization are systematized, whose social subjects overcome the bets of collective work, in the midst of the adversities of the problems of their world of life of the subjectivity that lives from the dispossession by urbanism.

Greater heterogeneity was observed in treatment approaches as the treatment algorithm progressed.

Perspectives on urban mobility in promoting physical activity in the context of commuting in Brazil / Perspectivas sobre mobilidade urbana na promoção da atividade física no contexto dos deslocamentos no Brasil

Despite Brazil's important advances in regulatory aspects related to city planning, the disorder-ly growth of Brazilian cities makes it difficult to implement changes that would result in greater opportunities for the active commuting of the population. This essay was designed to reflect on opportunities for improvement in the urban environment to promote physical activity in the context of commuting in Brazil. From this perspective, the study identified policies that promote orderly growth and support active commuting in cities. It also suggested the use of indicators to evaluate and monitor development, with a particular emphasis on active commuting. Furthermore, it is essential to adapt and improve the urban planning process to meet the needs of Brazilian municipalities and foster closer collaboration with civil society. Thus, it will be possible to verify the changes in the urban environment and their impact on the active commuting, promoting the development of healthy and sustainable cities

Apesar do Brasil apresentar importante avanço em aspectos regulatórios relacionados ao planejamento das cidades, o crescimento desordenado das cidades brasileiras dificulta a realização de mudanças que reflitam em maiores oportunidades no deslocamento ativo da população. Este ensaio foi elaborado com objetivo de refletir sobre as oportunidades para melhorias no ambiente urbano para a promoção da atividade física no contexto do deslocamento no Brasil. Nessa perspectiva, o estudo identificou políticas que permitem o crescimento ordenado e favoreça o deslocamento ativo nas cidades, além de sugerir o uso de indicadores para avaliação e monitoramento do desenvolvimento, com especial foco no deslocamento ativo. Ademais, é imprescindível que o processo de planejamento urbano seja adaptado e aprimorado considerando as necessidades dos municípios brasileiros e com aproximação da sociedade civil. Assim, será possível verificar as modificações no ambiente urbano e seu impacto no deslocamento ativo da população, estimulando a criação de cidades saudáveis e sustentáveis

Representações sociais de idosos sobre a mobilidade urbana na perspectiva do direito à cidade / Social representations of the elderly about urban mobility from the perspective of the right to the city

O envelhecimento populacional e a urbanização são dois fenômenos mundiais em crescimento e representam uma das transformações sociais mais significativas do século XXI. Esse cenário exige mudanças que envolvem a de modo particular. Objetivou-se analisar as representações sociais de idosos sobre a mobilidade urbana em Chapecó (SC), na perspectiva do direito à cidade. Trata-se de uma pesquisa qualitativa, em que foram realizados levantamento documental e entrevista semiestruturada. Participaram do estudo onze idosos integrantes do Projeto SUPERidade da Secretaria de Assistência Social de Chapecó. Para a análise das informações utilizou-se a técnica de análise temática de conteúdo, delimitando-se à categoria "Medo e Insegurança na relação com as barreiras". Os sentimentos de medo e insegurança constituem as representações sociais dos idosos sobre a mobilidade urbana quando estes se deparam com barreiras, como o tempo curto no semáforo, o degrau alto do transporte público coletivo e o desrespeito por parte dos condutores de veículos, cuja interação entre elas e as limitações funcionais oriundas do envelhecimento gera tais sentimentos. Tendo em vista que o envelhecimento é um processo progressivo, irreversível e previsível no curso de vida, é o espaço urbano que pode ser redimensionado e, assim, contribuir para a inclusão de idosos com diferentes graus de capacidade funcional no cotidiano da cidade. Eliminar as barreiras significa compensar as limitações funcionais e promover um espaço urbano mais justo, democrático e saudável.(AU)

Population aging and urbanization are two growing global phenomena and represent one of the most significant social transformations of the 21st century. This scenario requires changes that involve urban mobility, which is experienced by the elderly in a particular way. The objective was to analyze the social representations of the elderly about urban mobility in Chapecó-SC from the perspective of the right to the city. This is qualitative research, in which a documentary survey and semi-structured interview were carried out. Participated in the study, eleven elderly members of SUPERidade Project of the Secretaria de Assistência Social de Chapecó. For the analysis of information, the thematic content analysis technique was used, delimiting the category "Fear and Insecurity concerning barriers". Feelings of fear and insecurity constitute the social representations of the elderly about urban mobility, when they face barriers such as short time at traffic lights, the high step of public transportation, and disrespect on the part of vehicle drivers, whose interaction between barriers and functional limitations resulting from aging generate such feelings. Considering that aging is a progressive, irreversible, and predictable process in life, the urban space should be adapted to contribute to the inclusion of older adults with different degrees of functional capacity in the city's daily life. Eliminating the barriers means compensating for the functional limitations and promoting a fairer, more democratic, and healthier urban space.(AU)

Microplastics pollution in the Yellow River basin: current status and control strategy / 生物工程学报

Microplastics pollution has attracted worldwide attention. Compared with the status quo of microplastics pollution in marine environment and other major rivers and lakes, the relevant data of the Yellow River basin is relatively inadequate. The abundance, types, and spatial distribution characteristics of microplastic pollution in the sediments and surface water of the Yellow River basin were reviewed. Meanwhile, the status of microplastic pollution in the national central city and Yellow River Delta wetland was discussed, and the corresponding prevention and control measures were put forward. The results showed that the spatial distribution of microplastics pollution in sediments and surface water of the Yellow River basin increased from upstream to downstream, especially in the Yellow River Delta wetland. There are obvious differences between the types of microplastics in sediment and surface water in the Yellow River basin, which is mainly related to the materials of microplastics. Compared with similar regions in China, the microplastics pollution levels in national key cities and national wetland parks in the Yellow River basin are in the medium to high degree, which should be taken seriously. Plastics exposure through various ways will cause serious impact on aquaculture and human health in the Yellow River beach area. To control microplastic pollution in the Yellow River basin, it is necessary to improve the relevant production standards, laws and regulations, and improve the capacity of biodegradable microplastics and the degradation capacity of plastic wastes.

Improving home environments and pet-keeping hygiene is recommended to reduce the likelihood of B. hominis infection among children.

The first imported case of visceral leishmaniasis in Shenzhen City / 中国血吸虫病防治杂志

A patient with fever, chills, and pancytopenia as major clinical manifestations was presented. To investigate the cause, the patient’s peripheral blood was collected for pathogen screening using metagenomic next - generation sequencing (mNGS). The DNA sequence of Leishmania donovani was detected, and Leishmania amastigotes were found in bone marrow smears using microscopy. The case was therefore definitively diagnosed as visceral leishmaniasis, and was cured and discharged from hospital following treatment with liposomal amphotericin B for 14 days. This is the first imported case of visceral leishmaniasis since the founding of Shenzhen City in 1979.

Surveillance on dengue vector Aedes albopictus in Ningbo City in 2021 / 中国血吸虫病防治杂志

Objective To analyze the density, distribution and insecticide resistance of Aedes albopictus in Ningbo City in 2021, so as to provide insights into formulation of dengue fever control strategies. Methods Four administrative villages were randomly selected from each county (district) in Ningbo City from April to November, 2021, to investigate the indoor population density of Aedes larvae, and the Breteau index (BI) was calculated. The population density of adult mosquitoes was investigated in residential areas, parks/bamboo forests, waste tire stacking sites/waste stations/construction sites in each county (district). On June 2021, larvae of the natural strain A. albopictus were collected from epidemic sites of dengue fever in Ningbo City in 2018, and raised in laboratory. Then, larvae and female mosquitoes without blood feeding were selected for insecticide resistance bioassays, while insecticide-sensitive strains of A. albopictus served as controls. The resistance of A. albopictus larvae to deltamethrin, beta-cypermethrin, propoxur, temephos and dichlorvos using the impregnation method, and the medium lethal concentration (LC50) and resistance ratio (RR) were calculated. The resistance of adult A. albopictus to beta-cypermethrin, permethrin, deltamethrin, propoxur and malathion was determined using the tube bioassay, and the mosquito mortality was calculated. Results A total of 10 072 small water containers from 9 935 households were investigated in Ningbo City in 2021, and there were 1 276 containers with Aedes larvae detected, with an average BI of 12.89. Totally 1 422 mosquito nets were allocated and 954 female A. albopictus were captured, with an average net trapping index of 1.34 mosquitoes/(net·hour). Both larval and adult A. albopictus mosquitoes were found from April to November, and the density of larval A. albopictus peaked in September (BI = 21.21), while the density of adult A. albopictus peaked in August, with a net trapping index of 2.38 mosquitoes/(net·hour). The LC50 values of delta-methrin, beta-cypermethrin, propoxur, temephos and dichlorvos were 0.017 4, 0.000 9, 0.364 1, 0.038 1 mg/L and 0.001 6 mg/L against larvae of natural strains of A. albopicchus, with RRs of 49.66, 25.53, 9.65, 2.24 and 6.06, and the mortality rates of adult mosquitoes were 66.00% (66/100), 69.39% (68/98), 25.00% (25/100), 98.97% (96/97) and 100.00% (98/98) 24 hours post-treatment with 0.08% beta-cypermethrin, 0.03% deltamethrin, 0.4% permethrin, 0.05% propoxur, and 0.5% malathion for 24 h, respectively. Conclusions A. albopictus is widely distributed in Ningbo City, with a high population density and presents high-level resistance to common pyrethroid insecticides. The population density and insecticide resistance of A. albopictus requires to be reinforced.

Construction of a schistosomiasis transmission risk assessment system in Wuhan City based on analytic hierarchy process / 中国血吸虫病防治杂志

Objective To construct a schistosomiasis transmission risk assessment system in Wuhan City and preliminary evaluate its application effect, so as to promote the rational allocation of schistosomiasis control resources and accelerate the progress towards schistosomiasis elimination. Methods The schistosomiasis risk assessment indicators were collected through referring schistosomiasis surveillance data of Wuhan City from 2014 to 2020, literature review and expert interviews. Indicators within each criterion and sub-criterion were screened using the Delphi method, and a hierarchical structure model was created based on analytic hierarchy process. Quantitative assignment of each indicator was conducted according to relative importance, and the weight and combination weight of each criterion were calculated in each analytic hierarchy framework to create a schistosomiasis transmission risk assessment system, which was used for the schistosomiasis transmission risk assessment in 12 national schistosomiasis surveillance sites in Wuhan City. Results A three-level schistosomiasis transmission risk assessment system was preliminarily constructed, which included a target layer, 5 criterion layers and 21 sub-criterion layers. Of all indicators in the criterion layer, transmission route had the highest weight (0.433), followed by source of Schistosoma japonicum infection (0.294); and among all indicators in the sub-criterion layer, S. japonicum infection in Oncomelania hupensis and sentinel mice had the highest combination weight (0.125), followed by prevalence of S. japonicum infection in humans (0.091) and bovines (0.053), snail control by chemical treatment (0.049), positive rate of inquiry examinations (0.048), allocation of schistosomiasis control professionals (0.045), and areas of submerged snail-infested settings (0.041). Of the 12 national schistosomiasis surveillance sites in Wuhan City, there were 5 sites with weights of > 0.8, 4 sites with weights of 0.6 to 0.8, and 3 sites with weights of < 0.6 in 2020. Conclusion A schistosomiasis transmission risk assessment system has been constructed based on analytic hierarchy process in Wuhan City, which may provide a evidence-based basis for health resource allocation and decision-making for schistosomiasis control.

ObjectiveTo determine the epidemic characteristics of anthrax in Chengde City， Hebei Province from 2005 to 2021， and to provide evidence for formulating prevention and control measures of anthrax and reducing incidence rate. MethodsThis study collected the data of anthrax epidemic in Chengde City and conducted descriptive analysis. ResultsFrom 2005 to 2021， a total of 11 anthrax cases were reported in Chengde City with no death. The average incidence rate was 0.08/105， which remained low. Furthermore， 10 cases were cutaneous anthrax and 1 case was pulmonary anthrax. The cases were mainly reported in Weichang County， accounting for 90.91% of the total reported cases， followed by Pingquan City. In addition， the cases were mainly reported from July to August and mainly between 30 and 59 years old with a gender ratio of 2.67∶1. ConclusionThe anthrax epidemic in Chengde City is likely to increase. It mainly occurs in summer， rural areas， and male young and middle-aged farmers. It is necessary to improve epidemic monitoring， health education， disease prevention capacity， early identification of the epidemic， and active response.

Serological surveillance of human brucellosis in Ganzhou City， Jiangxi Province from 2018 to 2021 / 上海预防医学

ObjectiveTo describe the serological surveillance results of human brucellosis in Ganzhou City， Jiangxi Province from 2018 to 2021， characterize the epidemic and current situation of brucellosis， and to provide scientific evidence for effective prevention and control of brucellosis. MethodsSurveillance data of human brucellosis serological testing was collected in Ganzhou City from 2018 to 2021. Spatial， temporal， and demographic distribution was further determined. ResultsFrom 2018 to 2021， a total of 42 humans serologically positive for brucellosis were reported from 18 counties （cities and districts） in Ganzhou City， including 26 males and 16 females with a gender ratio of 1.6∶1. The number of serologically positive cases showed a decreasing trend， with the positive rate decreasing from 46.43% in 2018 to 33.33% in 2021. Majority of the cases （54.00%） aged 40‒ years old. Furthermore， the number of serologically positive cases varied by month； majority of the cases （80.95%） was from April to August. Additionally， a total of 10 counties （cities and districts） reported serologically positive cases of brucellosis， among which the top 3 counties （cities and districts） by cumulative number of positive cases were Zhanggong District （18 cases）， Dayu County（5 cases）， and Longnan City（4 cases）. ConclusionSerologically positive cases of human brucellosis decrease in Ganzhou， in which the incidence of male cases is generally higher than female cases. The seasonality of human brucellosis is in spring and summer. At-risk population is 40‒ years old. Additionally， at-risk areas are southwest and central areas of Ganzhou.
