The particulate matter PM10 concentrations have been impacting hospital admissions due to respiratory diseases. The air pollution studies seek to understand how this pollutant affects the health system. Since prediction involves several variables, any disparity causes a disturbance in the overall system, increasing the difficulty of the models’ development. Due to the complex nonlinear behavior of the problem and their influencing factors, Artificial Neural Networks are attractive approaches for solving estimations problems. This paper explores two neural network architectures denoted unorganized machines: the echo state networks and the extreme learning machines. Beyond the standard forms, models variations are also proposed: the regularization parameter (RP) to increase the generalization capability, and the Volterra filter to explore nonlinear patterns of the hidden layers. To evaluate the proposed models’ performance for the hospital admissions estimation by respiratory diseases, three cities of São Paulo state, Brazil: Cubatão, Campinas and São Paulo, are investigated. Numerical results show the standard models’ superior performance for most scenarios. Nevertheless, considering divergent intensity in hospital admissions, the RP models present the best results in terms of data dispersion. Finally, an overall analysis highlights the models’ efficiency to assist the hospital admissions management during high air pollution episodes.

Background: Intracranial trauma (IT) is an injury inside of the cranial box resulting from external forces, usually caused by automotive accidents, falls and violence, sometimes leading to permanent damage or death. Objectives: Describe hospital admissions for IT in the metropolitan region of São Paulo (SP), based on ICD-10 morbidity list. Design and settings: Epidemiological, descriptive and retrospective study. Methods: Data provided from the Hospital Morbidity System (SIH-SUS) of the Ministry of Health, from January 2015 to December 2020. Results: There were 65.455 cases of hospitalizations by IT registered in the metropolitan region of SP, which surpassed the cases of the North and Midwest regions. In 2020, there was a 5% reduction in cases compared to 2019. The amount spent represented 10.5% of the total spent in Brazil. Most of the hospitalization patients were male, and the most affected age group was 40- 49 years. The lethality was 11.05% and higher in patients over 80 years-old. Conclusions: It is essential to control IT’s causing factors, since it engenders high costs, and it is a serious problem for the public health and economy, and for the victim’s psychosocial context. The metropolitan region of SP requires special attention, once it shows higher rates of hospitalizations, morbidity, and mortality than any other brazilian state. Despite the social isolation in 2020, there were no significant differences between this year’s records comparing to the other ones.

Tillandsia usneoides is an epiphytic bromeliad that has been used as a universal bioindicator. The species accumulates metals and presents foliar scale variations when exposed to air pollutants. This study aimed to use the variations in foliar scales as microscopic markers of pollutant effects in the Metropolitan Region of Campinas (MRC), São Paulo State, Brazil. T. usneoides plants were exposed for 12 weeks during dry and wet seasons, totaling four exposures, at five sites in the MRC. Samples were selected before each exposure for initial evaluation of the plants (T0). Leaf fragments were fixed in glutaraldehyde and total scale density and anomalous scale percentage were evaluated. Plants exposed in the MRC showed anomalies and changes in number of subperipheral cells of leaf scales. When compared to T0, T. usneoides presented higher total scale density and anomalous scale percentage at disturbed sites, thus the species can be used as a pollution bioindicator for MRC.

This article investigates the application of economic indicators for the parametric estimation of public transportation aggregate demand. Since the transportation sector plays as vital role in a city infrastructure the objective is to present a method of selecting economic indicators that assist in the study of urban public transport demand, taking as a case study the Metropolitan Region of São Paulo (MRSP). Using econometric modelling, it was estimated the effect of variables explaining total traffic in the transport system, and more specifically examine the role of fares and the employment and wage indicators. Statistical tests were performed to check the validity of the analyzed models and develop a rank of indicators according to their performance as regressors. The subset of indicators that were representative of industrial activity and more related to the local economy had the best performance as a forecasting tool.

A presente análise objetivou avaliar as ações de planejamento e gestão do Turismo em áreas naturais protegidas da Região Metropolitana da Baixada Santista (RMBS) no Estado de São Paulo (Brasil), identificando em que nível estas ações foram influenciadas por conceitos e métodos propostos em dois programas mundiais da Organização das Nações Unidas (ONU): os Objetivos do Desenvolvimento do Milênio (ODM) e a Convenção sobre Diversidade Biológica (CDB). Enquanto a CDB já é amplamente difundida em programas de manejo e gestão do Turismo em áreas protegidas no Brasil, os ODM tiveram pouca penetração nesta temática. Subdivididos em oito metas globais, quatro delas têm amplo potencial para contribuir na elaboração de novas metodologias na gestão do Turismo em áreas naturais protegidas: o ODM 01 (redução da fome e da miséria); o ODM 03 (promoção da igualdade de gênero); o ODM 07 (respeito ao meio ambiente) e o ODM 08 (estabelecimento de parcerias para o desenvolvimento sustentável). Como resultado, a pesquisa demonstrou haver influência apenas indireta das metodologias propostas pelos ODM no que tange ao planejamento e gestão de atividades turísticas sustentáveis nas áreas naturais protegidas da RMBS, enquanto a influência da CDB foi facilmente identificável nas políticas e ações de planejamento e gestão do Turismo. Foram alcançadas algumas conclusões, como por exemplo, a de que os ODM passaram por uma clara adaptação ao contexto brasileiro por meio de políticas públicas, preferencialmente com relação ao ODM 01 (redução da pobreza). Quanto ao ODM 07, no qual o Turismo Sustentável insere-se como atividade econômica a ser incentivada na elevação do nível de renda das populações locais e em prol da conservação ambiental, este carece fortemente de políticas públicas assertivas. Sendo colocado pela ONU como primordial para o sucesso dos ODM em países em desenvolvimento, o Turismo Sustentável com base nos ODM e na CDB pode proporcionar significativos ganhos a áreas como a RMBS, permeada por complexas configurações urbanas, ambientais e sociais. Influence of global programs on the sustainability of tourism in protected areas of the metropolitan area of Baixada Santista (SP, Brazil) ABSTRACT This analysis aims to evaluate the action planning and management of tourism in protected natural areas of the Santos Metropolitan Region (RMBS) in the State of São Paulo (Brazil), whilst identifying at what level these actions were influenced by concepts and methods proposed in two global programs of the United Nations (UN): the Millennium Development Goals (MDGs) and the Convention on Biological Diversity (CBD). While the CBD is already widespread in management programs and management of tourism in protected areas in Brazil, the MDGs have had little penetration on this theme. Subdivided into eight global goals, four of them have vast potential to contribute to the development of new methodologies in the management of tourism in protected natural areas: the ODM 01 (reducing hunger and poverty); MDG 03 (promoting gender equality); MDG 07 (respect for the environment) and the MDGs 08 (establishment of partnerships for sustainable development). As a result, the survey showed that there was only indirect influence of methodologies proposed by the MDGs with regards to planning and management of sustainable tourism activities in protected natural areas of RMBS. While the influence of the CBD was easily identifiable in policy and action planning and tourism management, some conclusions were reached, including the MDGs passing by a clear adaptation to the Brazilian context through public policies, preferably in relation to the MDGs 01 (poverty reduction). As for the MDGs 07, in which Sustainable Tourism is inserted as an economic activity to be encouraged in raising the income level of local populations while conserving the environment, this strongly lacks assertive public policy. It has been placed by the UN as paramount to the success of the MDGs in developing countries Sustainable Tourism based on the MDGs and the CBD can provide significant gains in areas such as RMBS, permeated by complex urban, environmental and social settings. KEYWORDS: Millennium Goals; Biological Diversity; Sustainable Tourism; Protected Areas; Local Communities.
