Espaços de pobreza e mobilidade urbana: os deslocamentos da população de baixa renda em Natal/RN

This dissertation is an attempt to understand how families with an income of up to three minimum wages and living in different Areas of Demographic Expansion (AEDs) of Natal municipality specifically in the districts of Igapó and Salinas (North Administrative Zone of the city), Ponta Negra (South Administrative Zone), Santos Reis, Praia do Meio, Areia Preta and Mãe Luíza (East Administrative Zone) and Felipe Camarão (West Administrative Zone) solve their problems of urban mobility. It is, therefore, a reflection upon the mobility needs of poor urban households as expressed in terms of origin-destiny displacements for specific movements (house-work, house-school, house-shopping, house-healthcare and house-leisure), all of which being analyzed within the relationship between public transportation and poverty spaces of the city. In order to develop the study, theoretical aspects and themes related to the production of the urban space, to social and spatial segregation, to urban mobility and to transportation were confronted with the collected data referring to the urban population previously selected. One of the research main findings is the crucial role mobility plays in the social differentiation of such people living in Natal and that any policy for the improvement of their living conditions must take mobility issues into account

Efeitos da sintomatologia depressiva na mobilidade de idosos de um centro urbano do nordeste brasileiro

O processo de envelhecimento da humanidade é um fenômeno mundial e nas últimas décadas a população brasileira tem acompanhado essa tendência. No entanto, este fenômeno somente pode ser considerado como uma real conquista em termos sócios demográficos na medida em que se agregue qualidade aos anos adicionais de vida para a população. Em populações idosas, a incapacidade funcional e os sintomas depressivos tornaram-se importantes conceitos tanto por suas consequências para a saúde pública, quanto pelo impacto na qualidade de vida dessas populações. Este estudo tem como objetivo verificar se há associação entre os sintomas depressivos e o desempenho funcional de idosos comunitários. Foram avaliados 313 idosos de um centro urbano do nordeste brasileiro através das baterias de testes; Center for Epidemiologic Studies Depression CES-D e Short Physical Performance Battery - SPPB; além de variáveis relacionadas ao estado físico, condições crônicas, função cognitiva e características sócio demográficas. Foram utilizadas medidas de correlação e aplicado método de análise multivariada para construir um modelo explicativo da influência da sintomatologia depressiva no desempenho funcional. Os resultados revelaram que as mulheres apresentaram mais sintomas depressivos (p< 0.01) e pior desempenho funcional (p< 0.01) que os homens. Os indivíduos com sintomatologia depressiva apresentaram pior desempenho funcional, especialmente as mulheres. A idade, o sexo feminino, o estado de saúde percebido, o nível de função cognitiva e o Índice de massa corporal foram identificados como fatores associados ao desempenho funcional na amostra estudada. Os resultados deste estudo permitem inferir a relação de associação entre sintomas depressivos e desempenho funcional em uma população de idosos de um centro urbano no nordeste do Brasil. Estes resultados fornecem informações úteis para intervenções terapêuticas adequadas voltadas para a prevenção do declínio na mobilidade em idosos

Análise crítica dos produtos de mobilidade sentada - cadeiras de rodas - utilizados por crianças e adolescentes com paralisia cerebral em Natal/RN e outros municípios do Rio Grande do Norte

The objective of this work is to critically analyze the seated mobility adaptive equipment, wheelchair, used by non-ambulatory children/adolescents diagnosed with cerebral palsy of the quadriplegy type with ages in between 0-18 years old in the municipal city of Natal/RN and of other ones in the state of Rio Grande do Norte. This study is characterized as descriptive as it took into consideration the individualized conditions of each child/adolescent and of their home environment, and also evaluates the condition of the used seated mobility devices such as wheelchairs or strollers. Thirty three (33) subjects which had a wheelchair prescribed by a healthcare professional specialist in adaptive equipment within the past 3 years were selected. A questionnaire was applied through a phone with the patient s primary care giver or parents. The results obtained showed that all the equipment being used had an anatomical seat and back and the tilt system mechanism and even though most of the patients required small individual adjustments upon receiving the wheelchair in order to accommodate to the patients characteristics. From the point of view of the caregiver/parents interviewed, 97% described satisfied with the equipment and report assistance with mobility (97%), comfort (82%) and good posture (82%) as the main positive aspects from the equipment. The results also describe the aspects related to the maintenance, time used and activities developed that were reported by the patients. The conclusion therefore is that in order to select the equipment to meet the needs of the consumer it is necessary that: an appropriate wheelchair prescription takes place, the up-to-date knowledge of equipment available in the market, the appropriate use of the resources from the concession programs of the government that purchase equipment and the establishment of link in between the manufacturers, patients and the caregivers

Comparação e mobilidade, equilíbrio corporal e desempenho muscular segundo a auto-eficácia para quedas em idosas

The aging process modifies various systems in the body, leading to changes in mobility, balance and muscle strength. This can cause a drop in the elderly, or not changing the perceived self-efficacy in preventing falls. Objective: To compare the mobility, body balance and muscle performance according to self-efficacy for falls in community-dwelling elderly. Methods: A cross-sectional comparative study with 63 older (65-80 years) community. Were evaluated for identification data and sociodemographic, cognitive screening using the Mini Mental State Examination (MMSE), effective for the fall of Falls Efficacy Scale International Brazil (FES-I-BRAZIL), Mobility through the Timed Up and Go Test , the balance Berg Balance Scale (BBS) and the Modified Clinical Test tests of Sensory Interaction on Balance (mCTSIB), tandem walk (TW) and Sit to Stand (STS) of the Balance Master® System. Finally, muscle performance by using isokinetic dynamometry. Statistical analysis was performed Student t test for comparison between groups, with p value ≤ 0.05. Results: Comparing the elderly with low-efficacy for falls with high-efficacy for falls, we found significant differences only for the variable Timed Up and Go Test (p = 0.04). With regard to data on balance tests were significant differences in the speed of oscillation firm surface eyes open modified Clinical Test of Sensory Interaction on Test of Balance (p = 0.01). Variables to isokinetic dynamometry were no significant differences in movement knee extension, as regards the variables peak torque (p = 0.04) and power (p = 0.03). Conclusion: The results suggest that, compared to older community with low-and high-efficacy for falls, we observed differences in variables related to mobility, balance and muscle function

Extensões ao Projeto LVWNet: mobilidade, interação com equipamentos reais, comunicação direta, e registro dinâmico de nós

Due to the constantly increasing use of wireless networks in domestic, business and industrial environments, new challenges have emerged. The prototyping of new protocols in these environments is typically restricted to simulation environments, where there is the need of double implementation, one in the simulation environment where an initial proof of concept is performed and the other one in a real environment. Also, if real environments are used, it is not trivial to create a testbed for high density wireless networks given the need to use various real equipment as well as attenuators and power reducers to try to reduce the physical space required to create these laboratories. In this context, LVWNet (Linux Virtual Wireless Network) project was originally designed to create completely virtual testbeds for IEEE 802.11 networks on the Linux operating system. This paper aims to extend the current project LVWNet, adding to it the features like the ability to interact with real wireless hardware, provides a initial mobility ability using the positioning of the nodes in a space coordinates environment based on meters, with loss calculations due to attenuation in free space, enables some scalability increase by creating an own protocol that allows the communication between nodes without an intermediate host and dynamic registration of nodes, allowing new nodes to be inserted into in already in operation network

Análise da mobilidade urbana de Natal/RN a partir do uso de indicadores de sustentabilidade

In contemporary times, the urban mobility is presented as one of the main challenges of large and medium-sized Brazilian cities , it presents signs of unsustainability , above all due to the increase in motorized transport system , especially the individual . Thus , it is clear that mobility is considered of special interest for sustainable urban development , is facing a crisis that is reflected in negative externalities , particularly with regard to congestion , accidents , air pollution , social exclusion , among others. The complexity of these problems requires an integrated analysis based on the principles of sustainability . In this sense , trying to understand this problem and in the attempt to minimize its impacts, Costa (2008 ) proposed the Index of Sustainable Urban Mobility (I_SUM) with the goal of providing a methodology capable to assess relevant aspects of mobility , including social dimensions , political, economic and environmental . Given the above, was elected as the main objective of this study is to analyze urban mobility in Natal / RN from the perspective of sustainability . Like specific objectives will seek to analyze Natal´s urban mobility, using the I_SUM like a tool for both the city as a whole and for each of its four administrative regions; evaluate Natal s urban accessibility conditions and verify to what extent the access to urban services and equipment is facilitated or hindered because of the location and incomes of the population . For this, it was necessary to use bibliographic , documentary and field research . The index , which varies from 0.00 to 1.00, revealed for Natal an Global value of 0,510, and that refers to its administrative regions, it was found that there are very small percentage differences from the overall index calculated for the city . The performance of I_SUM by administrative region showed that although there are differences , the results were very similar , varying between 0,494 and 0,537. Particularly in relation to urban accessibility, it appears that Natal presents as an unequal city and this inequity , which is not only income is reflected in the issues related to accessibility and hence urban mobility

Território usado e transporte coletivo : mobilidade e acessibilidade no Bairro Lagoa Azul Natal/RN

Transport systems involved the use of territory in different Brazilian cities with regard to the occupation of road systems in urban areas. The implementation of systems engineering and transport infrastructure such as roads (roads), signs, stops, stations and complex road (bridges, viaducts and tunnels) are not used in the same way in the area. The subway is not even use the bus and vice versa. The time spent in travel, the time to access and the number of trips made by passengers in each way of transport is not the same. The use of transport systems in the territory, therefore, takes place through a whole in the current period we are in the technicalscientific and informational. This work addresses, however, the area used as a synonym of geographical area, analyzed by two categories of analysis, systems of objects formed by the fixed and the systems formed by the action flows. The system analyzed is the public transport by bus and population displacement that makes using this medium with source destination from home to work and has as empirical cut the Lagoa Azul located in the district administrative area north of Natal / RN. The general objective of this research is to understand the extent to which public transport has contributed to the socio-spatial accessibility of the residents of Barrio Blue Lagoon, located in Natal-RN, emphasizing the way home and the workplace. To reach the general objective of this dissertation, a study was made in light of the line which the methodological empirical facts, statistical data and theoretical knowledge of the events that occur in the quarter related to the Lagoa Azul economic aspects. Use for this, the concepts of mobility and Accessibility

Projeto de mobilidade urbana: estudo sobre processos de integração com habitação de interesse social nas obras do PAC da COPA 2014 em Natal/RN

The public political investments of urban mobility financed by PAC of Cup 2014 have developed discussions and questions by the civil society in Brazil expecting positive results to the urban infrastructure referring to the possible human rights violation and, specially, rights of habitation related to the removing/expropriation noticed. Natal, capital of Rio Grande do Norte, is into this context, due to the urban mobility project linking North Zone of the city to the Arena das Dunas stadium, financed by the PAC of Cup 2014, named West Structural Corridor, that crosses a field of social interest and proposes almost 400 expropriations. This research analyzes how strategies and mechanisms of integration were presented between the mobility project of West Structural Corridor and the Social Interest Habitation affected by this project. We have as hypothesis those projects financed by PAC of Cup 2014/Urban Mobility to Natal/RN present many problems related to the integration of social interest to the housing project, however the National Politics of Urban Development has planned this integration. As a result we detach 3 strategies in the elaboration process about the integration of those politics: (i) integration between municipal secretaries involved in this project; (ii) urban integration of the city; and (iii) integration of public rules or public politics integrated. For each strategy were presented the main mechanisms used to establish the integration of the project. Those mechanisms, however, in this process of establishment/implementation of the empirical research, presented many contradictions and conflicts that compose problems to the integration between the mobility project and the housing area affected.

Análise gráfica de elementos do design na interface de aplicativos de notícias baseados em mobilidade: um estudo do aplicativo Brasil 247

The different characteristics and needs of mobile device users, the situations in which these devices are operated and the limitations and characteristics of these devices are all factors which influence usability and ergonomics; two elements highly required for achieving successful interaction between users and devices. This research aims to identify characteristics of interface design for apps in mobile device applications, focussing on design, visual publishing and content editing, and the actual process of creation of these interfaces, with a view to guarantee quality interaction through touch technology, in observance of service limitations, the opportunities offered by the devices and the application requirements. The study will examine the interface of the mobile device application titled “Brasil 247” which provides news broadcasts using the concept of usability and ergonomics mainly in the field of adaptation, searching and browsing informative articles, as well as clarifying the processes and techniques necessary to carry out interaction tests which seek to evaluate the usability of interface.

Controle de mobilidade infraestruturado e orientado à qualidade para maximização de admissões em sistemas WiNeMO: uma abordagem definida por software

The spread of wireless networks and growing proliferation of mobile devices require the development of mobility control mechanisms to support the different demands of traffic in different network conditions. A major obstacle to developing this kind of technology is the complexity involved in handling all the information about the large number of Moving Objects (MO), as well as the entire signaling overhead required to manage these procedures in the network. Despite several initiatives have been proposed by the scientific community to address this issue they have not proved to be effective since they depend on the particular request of the MO that is responsible for triggering the mobility process. Moreover, they are often only guided by wireless medium statistics, such as Received Signal Strength Indicator (RSSI) of the candidate Point of Attachment (PoA). Thus, this work seeks to develop, evaluate and validate a sophisticated communication infrastructure for Wireless Networking for Moving Objects (WiNeMO) systems by making use of the flexibility provided by the Software-Defined Networking (SDN) paradigm, where network functions are easily and efficiently deployed by integrating OpenFlow and IEEE 802.21 standards. For purposes of benchmarking, the analysis was conducted in the control and data planes aspects, which demonstrate that the proposal significantly outperforms typical IPbased SDN and QoS-enabled capabilities, by allowing the network to handle the multimedia traffic with optimal Quality of Service (QoS) transport and acceptable Quality of Experience (QoE) over time.

Prevalência, fatores associados e efeitos da violência doméstica na mobilidade em idosos: evidências do estudo imias (international mobility in aging study) sob a perspectiva epidemiológica do curso da vida

A capacidade de mover-se com independência e segurança é fundamental para a execução das atividades de vida diária e manutenção da qualidade de vida do indivíduo. Diversos fatores, dentre eles o envelhecimento podem contribuir para seu declínio. Estudos têm demonstrado associação entre experiências de violência doméstica (VD) e diversos problemas de saúde física e mental. Até o momento, não há estudos que tenham avaliado a associação entre experiências de VD no curso de vida e limitações de mobilidade na senescência. OBJETIVOS: estimar a prevalência da VD (física e psicológica) em idosos, e avaliar o impacto da VD no curso de vida na limitação de mobilidade. MATERIAIS E MÉTODO: Estudo observacional analítico a partir da primeira coleta de dados do estudo longitudinal International Mobility in Aging Study (IMIAS). Idosos (n = 1995) de ambos os sexos entre 65 e 74 anos de cinco localidades distintas (Kingston e Saint-Hyacinthe, Canadá; Tirana, Albânia; Maniazales, Colômbia; e Natal, Brasil) participaram do estudo. Dados sobre variáveis sociodemográficas, econômicas, condições de saúde e experiências de VD (física e psicológica) durante o curso de vida foram coletados. A limitação de mobilidade na senescência foi avaliada pelo Short Physical Performance Battery (SPPB) e pela dificuldade de andar 400 metros e/ou subir um lance de escadas. As prevalências foram avaliadas mediante frequências absolutas e relativas das exposições à VD, limitação de mobilidade e co-variáveis. Diferenças de gênero, bem como entre cidades foram analisadas utilizando o teste de qui-quadrado. Associação entre exposição à VD e limitação de mobilidade foi avaliada utilizando a regressão logística binária multivariada, ajustando pelas co-variáveis. Análise de mediação foram utilizadas, para avaliar possíveis caminhos entre a exposição à VD no curso de vida e a limitação de mobilidade. RESULTADOS: A violência física foi rara, com valores entre 0,63 e 0,85%. Relatos de violência psicológica variaram entre 3,2% e 23,5% (homens) e de 9% para 26% (mulheres). Mulheres experimentaram mais violência do que os homens em Saint-Hyacinthe (homens: 3,2% vs mulheres: 14%, p <0,001), Tirana (homens: 4,3% vs mulheres: 10,3%, p = 0,017), em Manizales (homens: 8,3 % vs mulheres: 18,3%, p = 0,004) e Natal (homens: 11,1% vs mulheres: 26%, p = 0,002). Em geral, o baixo suporte social pelo parceiro foi associado com a VD. Estar trabalhando foi associado a vitimização entre os homens, enquanto o oposto foi verdade para as mulheres. Arranjos de vida Multi-familiares e baixo suporte pelos parceiros, filhos e família foram associados com a VD. Baixo suporte social foi da maior importância para as mulheres do que os homens. A VD física foi associada tanto com o SPPB < 8 (OR 1,623 95%IC 1,161-2,269) como com a dificuldade para andar 400 metros e/ou subir um lance de escadas (OR 1,394 95%IC 1,063-1,829). A limitação de mobilidade decorrente da violência física no curso de vida pelo parceiro íntimo foi mediada pelas condições crônicas (efeito 25,56% 95%IC 0,036-0,277) e depressão (efeito 33,05% 95%IC 0,087-0,333). No caso da violência física por outros familiares, a limitação de mobilidade foi mediada pelas condições crônicas (efeito 20,85% 95%IC 0,022-0,202), não adesão à prática de atividades físicas (efeito 34,14% 95%IC 0,076-0,351) e depressão (efeito 44,40% 95%IC 0,144-0,315). CONCLUSÕES: A violência doméstica no curso de vida é uma realidade, que pode acarretar consequências que favorecem a limitação de mobilidade em idosos. São necessárias políticas públicas que combatam efetivamente a violência doméstica, garantindo um envelhecimento mais digno e independente funcionalmente.

Espaços de pobreza e mobilidade urbana: os deslocamentos da população de baixa renda em Natal/RN

This dissertation is an attempt to understand how families with an income of up to three minimum wages and living in different Areas of Demographic Expansion (AEDs) of Natal municipality specifically in the districts of Igapó and Salinas (North Administrative Zone of the city), Ponta Negra (South Administrative Zone), Santos Reis, Praia do Meio, Areia Preta and Mãe Luíza (East Administrative Zone) and Felipe Camarão (West Administrative Zone) solve their problems of urban mobility. It is, therefore, a reflection upon the mobility needs of poor urban households as expressed in terms of origin-destiny displacements for specific movements (house-work, house-school, house-shopping, house-healthcare and house-leisure), all of which being analyzed within the relationship between public transportation and poverty spaces of the city. In order to develop the study, theoretical aspects and themes related to the production of the urban space, to social and spatial segregation, to urban mobility and to transportation were confronted with the collected data referring to the urban population previously selected. One of the research main findings is the crucial role mobility plays in the social differentiation of such people living in Natal and that any policy for the improvement of their living conditions must take mobility issues into account

Comportamento do consumidor: um estudo do mercado imobiliário em condomínios verticais fechados na região metropolitana de Natal

The research in question looked for to establish the relation between the motivation (of the proprietor of apartment) to change itself of another one apartment, in closed vertical condominium (residential mobility) in the period of the recognition of the necessity, and the satisfaction with the apartment after consume. The universe or the population chosen for the development of the study was of proprietors of apartment in vertical condominiums located in the region metropolitan of Natal. The analysis of data was made using the techniques of linear regression and logistic regression between variables. The linear regression found relations between the motivations for housing change and the satisfaction in after consume with some attributes of the apartment. The logistic regression showed that relations between the motivations for change and the general satisfaction to the apartment exist as a whole, in the period after consumes. With regard to the motivation to change itself of a apartment for another one, some reasons shown more motivation them the others. The research found different degrees of satisfaction with certain characteristics of the apartment and degrees of no satisfaction with others. Finally the results of the research had contributed for the reply of the problem that guided the present study, therefore had obtained in such a way to find how much logistic not linear relations between the two periods purchase (recognition of the necessity and evaluation after consume) and had elucidated the process that goes since the choice the product until the satisfaction of the necessities
