(Universidade Federal do Pará, 2022-05-24) NEVES, Raisa Rodrigues; FERNANDES, Lindemberg Lima; http://lattes.cnpq.br/4641468846318922
The research aimed to evaluate the quality of urban solid waste management, considering the actions taken and the information provided in the Municipal Plans for Integrated Management of Solid Waste (PMGIRS). For this, an initial matrix composed of 73 indicators was structured, which went through filtering stages, in order to extract information with low potential to be answered by municipal managers, giving rise to the final matrix of 40 indicators incorporated into 7 dimensions, basing the elaboration of the questionnaires used in this work. Initially, there was the application of questionnaires to managers to obtain knowledge about the reality of local management; then, the questionnaires were sent to the experts selected to participate in the Delphi Method. In total, 5 groups answered the questions on the 7 dimensions, which provided scores from 1 to 5 for each indicator and weights for each dimension. Based on the managers' responses, on the final grades of each indicator and on the final weights of each dimension, it was possible to calculate the Solid Waste Management Quality Index (IQGRS), framing the values found in sustainability levels. Then, the same methodology was applied to evaluate the quality of preparation of the PMGIRS, being proposed the Quality Index of the PMGIRS (IQPMGIRS), in this way it was possible to compare what was being done in practice and what was provided in the text of the instrument. of planning. As a result in terms of management, 4 municipalities presented unsustainable conditions, 4 presented regular sustainability, 5 presented good sustainability and only 3 presented excellent sustainability. After the application of clustering techniques in terms of management, 5 groups were formed, with Inhangapi and Canaã dos Carajás included in the group with the best performance; Abel Figueiredo, Augusto Correa and Curuçá were included in the group with the worst performance. Clustering was also applied regarding the quality of PMGIRS, guaranteeing the formation of 5 groups, with the group with the best performance being formed by Abaetetuba, Bonito, Goianésia do Pará and Juruti; the group with the worst performance was composed of Acará and Concórdia do Pará. The groups with the worst performances reflected the need for investments and progressions both in terms of management practice and in terms of improvements in PMGIRS, in order to guarantee the effectiveness of PMGIRS as a decision-making tool.

(Universidade Federal do Pará, 2022-09-30) VILLA-GARCÍA, Leidy Yurani; ZAMBRANO, Alfonso Claret; https://orcid.org/0000-0003-4795-6037; ALMEIDA, Ana Cristina Pimentel Carneiro de; http://lattes.cnpq.br/1265908866509687; https://orcid.org/0000-0002-9432-2646
This thesis proposes to advance the knowledge about the development of the Technological Pedagogical Content Knowledge (TPACK) in the training of bachelors, identifying the influence of the TPACK of the teacher educators who guide the disciplines of the teaching practice, in the teaching intentions of the teachers in training. on this specific case, the study addresses three central aspects: (i) Identification of the theoretical-methodological contributions evidenced by the state of the art (national and international) on the TPACK built before year 2020, (ii) Identification and analysis of the theoretical-methodological contributions that are evidenced in the TPACK of the mentor professors in the Natural Sciences Bachelor's program at UFPA, and the (iii) identification and analysis of the theoretical-methodological contributions of the TPACK of the mentor professors that are evidenced in the teaching intentions of the professors in training in the UFPA Bachelor's degree. The research used a qualitative methodology with an interpretive approach, as an instrumental case study, with which it was possible: characterize theoretical-methodological contributions that support the elements of TPACK in teaching practice and the indicators for their identification; identify the theoretical-methodological contributions in the practice of the mentor teacher through the analysis of the decisions and actions of the teachers who guide the disciplines of teaching practice during planning and teaching; and, finally, the theoretical-methodological contributions in the teaching intentions of the future teachers were identified. With this, the analysis leads us to verify that there is a projection of the TPACK of the mentor teachers in the teaching intentions of the teachers in training. Thus, the research offers a point of view on the inclusion of reflection in the dynamics of teaching practice in a specific context, in order to enhance the construction of the TPACK and contribute to improve the processes in which we learn to teach science from the experience. Among the relevant results, we can identify the theoreticalmethodological contributions that expanded the conceptual framework of the TPACK and allow us to analyze the TPACK that is being built through teaching practice in the Bachelor's degree. These results can be used by teacher trainers in postgraduate, undergraduate and basic education programs, as well as in open programs and courses with the intention that teachers in training and in service can identify their TPACK and develop it.

Desigualdade de renda, desemprego e pobreza nas regiões metropolitanas do Brasil: uma perspectiva heterodoxa
(Associação Keynesiana Brasileira, 2019) CARVALHO, André Cutrim; CARVALHO, David Ferreira; RODRIGUES, Phelipe da Silva
The present paper aims to deal with the theoretical and empirical view of the evolution of income inequality, unemployment and poverty in the Brazilian metropolitan regions from 2001 to 2011. For this purpose, it is necessary to recover the theoretical framework from the theories of John Maynard Keynes and even Hyman Philip Minsky. The main conclusion is that the social diagnosis, during this period, showed an impressive reduction in income inequality and poverty. In this way, it can be seen that the reduction of income inequalities are extremely important parameters for the expansion of the national domestic market. On the other hand, family income transfer programs, such as “Bolsa Família”, have contributed to the reduction of absolute poverty. Last, but not least, the results obtained through social indicators could attest to this fact.

(Universidade Federal do Pará, 2023-01-26) COSTA, Magaly Santos Pinheiro; PEREIRA, José Almir Rodrigues; http://lattes.cnpq.br/9918600634569244
With the unavailability of financial resources and the high cost of implementing conventional sanitary sewage systems of the absolute separator type, regions with disorderly occupation and, often, subject to unfavorable topographical situations, end up not being contemplated with basic sanitary sewage services. Complementarily, this issue is accentuated by the lack of local references regarding the costs of implementing sanitary sewage collection networks in Pará, as well as parameters for the conception and elaboration of projects in the state context. In this sense, it is necessary that the typology of the sewage network to be implemented in each location be carefully planned, bearing in mind the particularities of each area, as well as the technical criteria to be adopted in the project. Considering the problem addressed, the objective of the present research was to establish values, expressed in R$/m of COSANPA's sanitary sewage collection network project, for analysis and identification of the budget worksheet items referring to the collection network and household connections, being updated the costs in the spreadsheet for the base date October 2022. In the first stage, the projects and works of the sewage collection network were surveyed in the COSANPA and SEDOP database, from this survey, the projects were selected for the preparation of the Technical Sheet, containing the main information on the sanitary sewage system. In the second stage, from the budgets of each project, the construction values practiced in projects and works of sanitary sewage collection network under the management of COSANPA and SEDOP were identified, then the budgets were analyzed and the values for the same were updated. base date (October 2022), using the National Civil Construction Index – INCC of the Getúlio Vargas Foundation – FGV. In the third stage, the values of the sewage collection network of each project were compared. In the fourth stage, a range of values for the construction of a sewage collection network was presented, expressed in R$/meter of network. This range of costs will make it possible to determine a regional reference indicator regarding the implementation cost per meter of the sanitary sewage collection network, allowing its application in studies, reports and regional projects for the collection network; contributing with Specialized Consultancies, with Higher Education Institutions and with the Public Power, with actions that culminate in the increase of sewage coverage in the Metropolitan Region of Belém.

(Universidade Federal do Pará, 2012) NOGUEIRA, Ana Caroline Neris; SILVA, Luis Mauro Santos; http://lattes.cnpq.br/7285459738695923; https://orcid.org/0000-0003-1311-1271
This study aimed to evaluate the process of diversification of agroecosystems located in the southern portion of Pará, departed from the sample that participated in the projects that the CPT performed in order to guarantee the food sovereignty of the settler families by offering diversified products and conservation environmental awareness courses with the use of fire as a management and the effect of specialization in cattle raising and training courses on the implementation of productive activities. These initiatives have started a phase where the context for the establishment of diversification was unfavorable, that due to lack of public policies, low investment capacity of farmers and cattle farming on the forest. At this stage, there have been farmers who chose to diversify, some have managed to maintain diversification, but others did not carry on activities. Subsequently, the second phase of the historical region that began late in the 1990s, enabled a larger opening investment of the federal government, through public policies that started to incorporate the family farm, PRONAF (founded in 1996) was a good example. Even in this more favorable context was not possible for many families opt for diversification and not that they were able to maintain their productive activities.To understand the factors that led to withdrawal or that favored the installation of diverse projects is necessary to go beyond the aspects extra lot to understand the peculiarities of each situation, as well as projects of the family are crucial to understanding this process. The assessment of sustainability wide agroecosystems was ensured by the use of the tool MESMIS, the indicators raised in the environmental, social and economical solution showed a high diversity of realities, the best performance among the agroecosystems of the two phases, is in the 1st phase of history the region and the worst performances in the 2nd phase of dynamic change in production, it strengthens the internal aspects of agroecosystems, their limitations and strengths are crucial to the success or failure of diversification. The size was a more fragile environment, some families do not have the native area, or the entry by fire or livestock feed. In the social dimension, the labor was the most significant indicator, as in the technical-economic indicators most significant were the efficiency of management (limitation, income, productive diversity) and the current diversity of agroecosystems.

(Universidade Federal do Pará, 2022-04-28) LOPES, Luiza de Nazaré Almeida; TEIXEIRA, Luiza Carla Girard Mendes; http://lattes.cnpq.br/9773700229115395
Dengue is one of the neglected tropical diseases that is important for public health in Brazil, as it inspires attention due to the increased incidence of cases influenced by macro and microfactors that provide favorable conditions for the expansion of mosquito vectors and transmission of the dengue virus (DENV). The research proposes the ecological study of dengue and the construction of a Dengue Socio-environmental Vulnerability Index (IVD) to analyze 143 municipalities in the state of Pará. The IVD design considered the selection of 34 indicators of the three fundamental components of the vulnerability concept: exposure, sensitivity and adaptive capacity. The methodology consisted of the following steps: (i) selection and grouping of indicators; (ii) definition of indicators; (iii) statistical treatments; (iv) calculation of the index by multivariate analysis; (v) index normalization; and (vi) index classification using the percentile technique. In the survey, 184,000 cases of dengue were considered, of which 92,000 progressed to hospitalization by the SUS, in the period from 2001 to 2017. The epidemiological profile of dengue indicated a seasonal behavior of the disease, occurring mainly in the quarter from January to March . For the construction of the IVD, the period from 2007 to 2017 was considered, in the mapping results it was observed that 43 municipalities (30%) were classified as "Low vulnerability", with values ranging from 0.483 to 0.262. About 57 municipalities (40%) presented values with “Medium vulnerability” in the range of 0.581 to 0.483. With reference to “High vulnerability”, 43 municipalities (30%) stood out, distributed in the range from 0.771 to 0.582. The results obtained from the profile that characterized the IVD showed a predominance of “Medium to Low vulnerability”. The city of Belém, capital of Pará and located in the Guajará region, presented the lowest value for IVD (0.262). On the other hand, most municipalities in the Marajó region had the highest IVD values, namely: Cachoeira do Arari, Chaves, Ponta de Pedras, Melgaço, Santa Cruz do Arari and Anajás. The indicators that most influenced the result of the index was the “socioeconomic” factor of the populations, especially related to poverty, income, urbanization, illiteracy and solid waste management. From the application of the IVD, it can be stated that it can be used as a relevant tool for the management of dengue health surveillance in the municipalities of the Amazon region, with the potential to be studied in other regions of Brazil.

This research was motivated by the professional and personal experiences of the teacher and author of this thesis and aimed to understand the development processes of scientific literacy and literacy in the mother tongue, based on teaching practices through the Science, Technology, Society and Environment (STSE) approach, and also to identify indicators of these processes. For the development of the research it was necessary to define and defend the use of the concepts and theoretical basis of the STSE approach, literacy in the mother tongue and scientific literacy as well as its relationship with science research and teaching. The methodology of the study adopted a qualitative approach, from the pedagogical intervention type, which took place in a public elementary and high school, in a municipality in the state of Pará, with the participation of students graduating from the 6th year of elementary school. The activities developed during the intervention were based on the socio-environmental theme “The Tidal Phenomenon”, considering scientific, technological, social and environmental implications of this theme, from the perspective of Teaching by Research. The instruments used for the constitution of data were: audio and video recordings, photographs, questionnaires, registration of students' activities and the teacher's research diary. For data analysis and interpretation, Discursive Textual Analysis (DTA) was used. Through the results, the thesis defends that science teaching activities through the STSE approach in elementary school, from the perspective of the involved study, promote learning with the development of scientific literacy and literacy in the mother tongue, showing indicators. The constituted data allowed us to verify that the teaching activities through the STSE approach enable contributions regarding the expansion of the students' vision, the expression of everyday language and the development of scientific language, with natural conditions of reading and writing and the adoption of a more active attitude. The development of activities also led to the proposition of indicators of scientific literacy processes in the mother tongue, observed in the analysis, to evidence the construction of scientific knowledge and reading and writing skills through the STSE approach, considering the decision-making capacity development process. The indicators are: obtaining information, organizing information, interpreting information, articulating text and context, communicating ideas, preparing questions, articulating term and concept, analysis and judgment, expression of action strategies and selection of action. These indicators were organized into three grouping blocks. They are: Reading and Contextualization; Thought and Integration; Decision and Action. The results allow us to affirm that the students were in the process of developing scientific literacy in their mother tongue and that this research contributes to the field of Science Teaching, representing advances in the construction of knowledge from the perspective of teaching and training of teachers.

The concern with routine maintenance is usually related to a failure of process or equipment (corrective maintenance). The systematic control of maintenance and operation of machinery and equipment is considered a high point for reducing costs and increasing operational readiness for strategic planning. As a result, it has been in service area, a large number of methods, software models and management tools available. Among them, two methods stand out: the RCM (Reliability Centered Maintenance and Reliability Centered Maintenance) of U.S. origin, and TPM (Total Productive Maintenance and Total Productive Maintenance), of Japanese origin. Thus, the main objective of this work is the systematic study of strategic planning and planned maintenance to reduce failures and defects that occur in equipment from the proposed methodologies by leading authors in the area of strategic planning and maintenance, in order to propose improvements in the use of this tool. Based on the theoretical (Amendola, Berndt, Coimbra, Right, Coser, Nakajima, Mendes Moreira, Moubray, Oliveira, Kaplan and others) studied, could begin to understand the planning of the management of planned maintenance of the Tucuruí Hydroelectric Plant and their practices in relation to the performance practices of reference and key strategic indicators highlighted by these authors. This research allowed to evaluate the current procedure adopted at Tucuruí is aligned with all the thinkers studied by simply spreading the best of all concepts hieraquics between all levels of planning and execution.

Sanitation and health are inseparable. Under this premise, is conducted the investigation contained in this study, that looks for to contribute offering to the society a new interdisciplinary point of view in the formulation and accompaniment of the public politics of urban sanitation. The use of urban indicators is improvement factor in the planning and administration of the cities, and matter up to date. There is abundance of them, however this study search the cognitive simplicity, although without reductionism, and there the concern resides with the Interdisciplinarities contained in the approach of this investigation, that culminates with the proposition of econometric model relating social and sanitary data censes. They are studied the relationships among mortality in the childhood, urban population, provision of urban services of water supply, sanitary exhaustion and waste collects. The explanatory relationships are verified among dependent's variable constituted by the product mortality in the childhood x urban population and the variables independent urban populations assisted with water supply, sewerage system and garbage collect. Considered the expressed politics of investments in sanitation in the General Budget of the State of Pará for the year of 2006 as usual, and starting from the developed model, the mortality in the childhood is inferred for the year of 2015, and compared with the Goal 5 of the Objectives of Development of the Millennium of UN, which consists of the reduction of the mortality in the childhood in 2/3 among the years of 1990 and 2015. The estimates of resources for the attaining of that Goal indicate the need to maintain the investments in water supply, collects of garbage and to increase them in sewer sanitarium. As logical consequence of the reasoning and of the analyses contained in the work, it is suggested as allocation criterion in the planning of resources for amplification of the provision of urban services of sanitation the mortality in the childhood.

Proposta de indicadores de desenvolvimento socioeconômico e ambientalmente/ecologicamente sustentável – o IDHA e o IDHE
(Companhia Brasileira de Produção Científica, 2018-08) CARVALHO, Rhayza Alves Figueiredo de; CARVALHO, Abner Vilhena de; TANAKA FILHO, Mario; ALMEIDA, Rodolfo Maduro; GUIMARÃES, Jarsen Luis Castro; BARROS, Márcio Júnior Benassuly; CARVALHO, Ednéa do Nascimento; CARVALHO, André Cutrim
This paper aims to propose the development of two indicators that incorporate the sustainable perspective in its methodological framework, from the inclusion of an environmental / ecological dimension, together with the other traditional dimensions of human development (standard of living, life expectancy and access to knowledge. ), in order to verify the importance that this environmental metric reflects in the analyzes of a broader development, filling a gap left by the traditional indicators, which do not consider the environmental dimension as an integral part of the analytical instrument. The inclusion of such a dimension is extremely relevant in the development and sustainability analysis, as it has a direct impact on the population's quality of life. Therefore, the environmental quantification is proposed through two indices: the Environmental Quality Index and the Ecological Footprint, which verify aspects of the quality of the environment as well as biophysical aspects. Then, these environmental indices will be incorporated into the economic (per capita income) and social (education and health) dimensions, allowing to identify the level of human development of a given locality. The results of the study allow us to analyze the level of environmental quality, as well as to indicate the level of human development, showing the essentiality of the environmental dimension in the construction of development indicators, especially of a sustainable nature, which may present itself as a factor that reduces or it increases the level of development of a locality when compared to different ones, allowing comparative analyzes by the ranking method or by the impact estimation through economic-environmental modeling.

Anthropogenic pressure on water resources has been increasing due to the lack of efficient management, demographic growth, and the intense exploitation of natural resources. In this sense, the Maracanã River Basin (BHRM), located in the coastal zone of the state of Pará, has particularities that involve the influence of river and tidal regimes; its potential use for tourism, extractivism, and agriculture, as well as the need to carry out research in this region, mainly through an integrated and systemic analysis. Therefore, the research aimed to analyze the water sustainability of BHRM, through the Water Sustainability Index (WSI), to support the integrated planning of the basin. The methodological procedures involved: I) construction of indicators of the Hydrology for the Environment, Life and Policy (HELP) dimension in the water units of the basin, II) Calculation of the WSI in the water units of the basin, III) Compartmentalization of the basin, and IV) analysis statistics of results. The results showed that environmental degradation in the basin's water units, especially in the middle and upper reaches regions, it is correlated with the percentage of vegetation cover. The low social and political indicators of the municipalities are reflected in the management of BHRM. The WSI presented an intermediate value of 0.63, with the Environmental and Political indicators showing the highest values, being 0.86 and 0.74 respectively. The lowest indicators were Hydrological (0.60) and Social (0.32), which were reflected in the average final value of the WSI. Thus, advances are needed in water governance in the BHRM, which mainly involves the instruments of water and coastal resource management policies, aiming for an integrated management of the BHRM. The results can contribute to listing the potentialities and weaknesses highlighted in the research, supporting the integrated planning of BHRM.
