(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.

(2011-06) OAIGEN, Ricardo Pedroso; BARCELLOS, Júlio Otávio Jardim; CANOZZI, Maria Eugênia Andrighetto; CHRISTOFARI, Luciana Fagundes; SOARES, Jean Carlos dos Reis; ALVES, Carine Oliveira
The present research aimed to identify the main internal factors (costs, income, techno-economic feasibility and technologic innovation use) which affect the beef cattle activity competitiveness in a complete cycle production system in the state of Rio Grande do Sul. The data was collected during the year of 2008 based on monthly meetings between the months of January and December. Later the data was analyzed in eletronic spreadsheets. The costs were subdivided in disbursed, operating and total costs and the income in category and total. Among the evaluated costs, the land opportunity cost, labor force and animal supplementation with values of 19.9%, 18.3%, 13.6% respectively, can be pointed out in relation to total cost. The main financial and technical indicators commonly used in production systems analysis were calculated. The economic margins (gross, operating and net), as well as the profitability over the net worth were positive which show economic feasibility in the activity. At the same time, technical indicators as the output rate and the productivity/ha showed satisfactory values. Thus it can be concluded that the evaluated internal factors were very competitive for the studied system.

Comunidades tradicionais em áreas litorâneas da Amazônia: estudo sobre desenvolvimento local em Vila Mota, Pará, Brasil
(Universidade Federal do Pará, 2014-04) PINHEIRO, José Olenilson Costa; DARNET, Laura Angélica Ferreira
The paper presents the socioeconomic dimension in Vila Mota, municipality of Maracanã, state of Pará, and its repercussion in the local development process, understood as the fulfillment of basic human needs. Vila Mota is a community of traditional fishing located in the Reserva Extrativista Marinha de Maracanã (marine extractive reserve). The conditions of life in this community were observed and analyzed according to some indicators that make up the Human Development Index (HDI) and its variants. Limiting and enhancer factors for local development were also identified. The survey was carried out in 2007 and took into account 72 families representing 48% of the total available. The results indicated that housekeeping was impaired in families that have developed small-scale fishing as the only productive activity, given that the monetary income for 62.5% of these families was less than a minimum wage. The conditions of education and natural resources were enhancer factors to the development, although the most part of inhabitants did not know the purposes of the marine reserve. The absence of a cooperative culture, the lack of a structure for production, transportation and marketing, and the disability of health services were evidences of a low capacity for socio-political organization, with direct impact on local development.

(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.

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, 2016-05-06) LADISLAU, Antonio Pereira; TOMA, Marina Yassuko; http://lattes.cnpq.br/6883396550618718
This study aims to analyze the indicators of Elementary Education quality in Breves city, in Portuguese and Mathematics teachers' view, looking to find how the lack of use of these indicators by the school community in their planning have been contributing to a low performance of basic education development in Breves city. The research, a descriptive one, it was carried out with 91 Portuguese and Mathematics teachers from elementary school, the 5th grade and 8th grade, 47 teachers from urban and 44 rural area. The results showed that the profile of the education professional from Breves is relatively young, In view of that almost the half of the respondents (49,45%) corresponds to an age group between 30 to 39 years old, and 82 (90,11%) are between 25 to 49 years old, with an average of 12 years of work. Besides they have a professional stability, since 78 (85,71%) had made a contest. The result also showed that 85 (93,41%) of the respondents have Higher Education and or Specialization, which allows continuity with regard to a plan with targets to be achieved in the short, medium and long time. However, the educational indicators that point to the performance of teaching quality are not discussed by the school community, a fact which is pointed out by the most teachers from rural and urban areas. It was also ascertained that the director / educational coordinator not discuss the educational targets with the teachers, this reality marked by the majority of respondents from rural areas. If the educational indicators are not discussed in educational planning with teachers and there is no effective participation of parents within the school community, it is committed the participation of the teachers in front of the national education quality assessments, earned by the Brazilian government, at school institutions

In a scenario in which organizations seek effective results and in which the workers are not seen as a resource, but as collaborators who must understand what is expected of them and how they can contribute to the organization and, on the other hand, how these workers can be motivated and valued in their daily work, through the perception of the results of their work, this research aimed to analyze the performance evaluation performed at the Federal University of Pará (UFPA), based on the Balanced Scorecard method (BSC), from the perspective of the public employees of the position of executive secretary. To this end, the following objectives were established: to identify individual performance measurement method, based on the BSC method; to define three or more individual performance indicators for UFPA executive secretary public employees; and to analyze these individual performance indicators as a tool for managers' decision making. The research methodology was conducted from a post-positivist quantitative approach, carried out through literature review and field research. The field research was applied through a survey, which was validated with a sample of the universe of individuals, and was then applied to the general population. The results obtained had their consistency proven from Cronbach's alpha. The research pointed out that it is possible to elaborate individual performance indicators from the definition of the expected percentage of execution of a given public employee activity and the expected quality criteria, which are derived from the Institutional Development Plan (PDI). After that, six indicators were aligned with the BSC’s Internal Processes perspective and were proposed according to the strategic objective “Improve institutional communication”. These indicators were used to analyze the perspectives of: elaboration of the work plan of the server, proposition of training and qualification, and dimensioning of the work team.

(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.

The colonization of northeaster Pará is considered one of the oldest at Amazon area, where a disorderly occupation over time caused several impacts on the environment and water resources, mainly related to the territory of the hydrographic basin of the Marapanim River. In this context, the research aimed to integrate concepts of water demand and availability, adding hydrological and socio-environmental factors to the analysis of the hydrographic basin as a natural unit of area for the management and application of public policies in the municipal cities of Castanhal, Igarapé-Açu, Marapanim, São Francisco do Pará and Terra Alta, which belong to the hydrographic basin of the Marapanim River. The goal of the research was to evaluate the management process of those localities, through sustainability index with Pressure - State - Response (PER) indicators, combined with the characterization of multiple uses of water. The main demand for water in those localities is public water supply, with an estimated volume of 2,228.18 m³ / day. However, within the limits of the locality, agriculture was the activity that were responsible for the higher demand, 28,022.46 m³ / ha, followed by livestock production, 899, 82 m³ / day. The region's water availability was estimated by rainfall monitoring, in which September-October-November were months with fewer rainy days, with the highest percentage of rainfall in the month concentrated in a few days. The sustainability index of the municipal cities of Castanhal, Igarapé-Açu, Marapanim and Terra Alta were 0.40; 0.50; 0.44; 0.54 and 0.5 respectively, which represents an average value. The city of São Francisco obtained an index value of 0.54, considered as a good index value. The characterization of multiple uses of water is essential to understand the relationships of availability and demand for water that occur at hydrographic basin of the Marapanim River, as well as the application of the sustainability index based on the pressure - State - response model, allowing both integrated and individual assessment of hydrological, environmental, political and social indicators, which allows a more targeted view of the needs of each territory, thus helping to guide public policies managers during decision making process.

The aim of this study was to evaluate the relative validity of indicators of food and beverage intake obtained from the telephone interview surveillance system (VIGITEL). A random sample (n = 100) was evaluated from the total sample of approximately two thousand adults studied by the system in 2009 in Belém, Pará State, Brazil. The indicators were protective factors (adequate consumption of fruit, vegetables, and leafy vegetables) and risk factors (consumption of saturated fat, soft drinks, and alcoholic beverages) for chronic non-communicable diseases. The telephone interview results were compared with those of three 24-hour recalls (reference standard). The reference standard showed underestimation in the indicators' frequency, except for soft drinks and alcoholic beverages. The mean consumption frequencies were generally higher in the exposed group interviewed by the VIGITEL system. We cannot conclude that the VIGITEL system is not a good indicator of consumption, since the reference standard also shows limitations. Nevertheless, its use as a surveillance tool in Brazil is justifiable.
