National port development is directly related to the efficiency of the international commercial links that the country establishes, as well as to international commercial relations, which depends on the capacity to use the existing waterway network in the national territory, the use of which is currently resumed at 30% of its waterway potential. Therefore, in recent years, investments have been made in the area of river transport, focusing on states with the highest concentration of rivers. As river ports begin to gain strength in favor of logistical dynamization, there is a need to evaluate their efficiency to investigate the relationship between criteria such as location, berthing capacity, waterway flow. Based on this, this research aims to analyze the efficiency of 10 Waterway Terminals in the Lower Amazon region, opened between 2021 and 2022, for which Data Envelopment Analysis was applied (DEA). Variations in results for the terminals considered will be elucidated, making it possible to evaluate port efficiency using a method and relate how it is capable of meeting logistical demands and river traffic in the region, but also to investigate the different results obtained and how these are relate to the characteristics of the terminals in question. We also sought to demonstrate the importance of studies like this to understand the impact caused by waterway terminals, going beyond the economic scope and influencing the growth of regions by providing quality connections between municipalities that primarily depend on river transport, mainly in cities hub such as the municipality of Santarém. Finally, it was identified that four of the ten waterway terminals analyzed are operating at maximum efficiency. These terminals have demonstrated the ability to effectively convert their resources.

This study aimed to investigate which integration regions are considered inefficient in the application of their resources. The research is structured based on the discussions proposed by the theoretical framework throughout two chapters that address the Theory and the Managerial Public Administration model, based on the principle of efficiency, according to the model proposed by Bresser-Pereira in the 90s, highlighting the regulatory frameworks, and finally, a literature review, based on Povedano et al. (2021). For this, Data Envelopment Analysis – (DEA-BBC model) was used, output-oriented, which makes it possible to comparatively analyze the efficiency of DMUs. To measure the efficiency of Municipalities' spending, data from INEP and the Transparency Portal of the State Attorney General's Office were used. The DEA results indicated that the Tocantins RI obtained the lowest efficiency score, with increasing returns to scale, indicating that to achieve efficiency, optimal use of inputs is necessary, necessitating some reductions in its numbers of teachers and schools, so that each municipality remains on the production frontier. The scale efficiency had an average of 0.3968. These results show that the municipalities in the state of Pará urgently need to have a better use of inputs in relation to expenses, which may have been caused by the poor application of public resources, which should be reviewed by the mayors and by the governor of the State of Pará, with the insertion of public policies to reverse this situation of inefficiency in Elementary Education

Importância da frequência de descarte de lodo na eficiência dos decantadores de estações de tratamento de água em ciclo completo
(Universidade Federal do Pará, 2004-10-20) CUNHA, Márcia Valéria Porto de Oliveira; PEREIRA, José Almir Rodrigues; http://lattes.cnpq.br/9918600634569244
In this work, different periods of discharge of the sludge stored in the decanters of the ETA Bolonha had been evaluated, with the purpose to recommend the operational routine that presents the best ones results in the efficiency of the decanters. The three experimental phases had been divided in three stages: being in phase 1 evaluated the efficiency of the current operation routine of the decanters what is the total discharge of sludge in 12 in 12 days. In phase 2, the operational routine was modified to a daily discharge during the time of 5 minutes and so it coud take care of the recommendations of the executive project; by the other hand, in phase 3, the operational routine was modified again, discharge of sludge of 5 in 5 days during the time of 5 minutes, in order to getting better results of efficiency. In these three phases it was realized the control of total suspended solids, dimming and color in the effluent tributary and, as well as quantified and characterized the sludge generated in the decanters. With the research it was possible to observe that according to the point of view of efficiency of the decanters, the implemented operational routine in phase 3 (discherge of sludge to each 5 days) it was showed more adequate. By the way, it recommends that tests with other operational routines should be done in order to remove the sludge deposited in the decanters to diminish the losses of water of this operation. Moreover, it is important to study other ways to remove the deposited sludge in the intermediate tray of the decanter to prevent the accumulation of sludge on tray.

Indicadores de desempenho de portos públicos e privados: estudo de caso de terminais de conteineres brasileiros
(Universidade Federal do Pará, 2019-07-09) SANTOS, Nadyme Tayane Silva Ramos dos; NEVES, Renato Martins das; http://lattes.cnpq.br/6538317425557058; DUARTE, André Augusto Azevedo Montenegro; http://lattes.cnpq.br/1135221873341973
In recente years, a significant number of countries have implemented policies to reform their port industry. In the belief that efficiency will improve, privatization has been widespread, believing that the transfer of management from public hands to private ones, will lead to improvements in the levels of economic and operational efficiency, bringing a competitive advantage in the world market. This paper sought to investigate the validity of this assertion based on theoretical foundations as well as with the adoption of port performance indicators developed by ANTAQ, adapting methodologies that can measure the efficiency of public and private port terminals in the period of 2013 to 2018, comprising 06 years. For this purpose, 8 port units were defined, composed of 04 public and 04 private ports. The results obtained allowed to compare the sectors and to analyze the efficiency between them. During the study, it was noticed that the public sector presents more worrisome indicators for port management, mainly, related to productivity and the level of service obtained, and should be analyzed more comprehensively in the context of infrastructure and equipment to provide investments in this scope, considering that these parameters also have influence on these results.

Regime de dedicação exclusiva: desafios e perspectivas na Universidade Federal do Pará
(Universidade Federal do Pará, 2020-12-17) MIRANDA, Liovanny Alves Favacho de; TEIXEIRA, Eliana Maria de Souza Franco; http://lattes.cnpq.br/5865287894194983
This research consisted of verifying, through the evolution of the Brazilian Public Administration, the way in which the lack of internal regulation in the Federal Institutions of Higher Education, about the Exclusive Dedication Regime, contributes to the occurrence of cases of transgression to that work regime. The referential started from a historical focus on how the theoretical contribution related to public management evolved to the present approach, based on results-oriented management and guided by the principle of efficiency to clarify the mechanisms that strengthened social control and, therefore, the identification of infringing acts such as transgression to the DE regime. The methodological procedure used to implement the research objectives, as to the purpose, can be classified as "applied or practical research", in addition to explanatory research, using data from documentary research, based on secondary data. In this sense, the data collection process had two stages: first, the collection of Resolutions, from the websites of the Superior Councils and academic units, having adopted, as a criterion for sample selection, the existence, in the content of the Resolution, of devices that regulated the exceptions provided for in art. 21 of Law no. 12,772 / 2012; in the second stage, the data already compiled by CGU were used, through the management track n. 201413612, made available through three spreadsheets of the excel software. In this sense, the information worked on in this stage was extracted from the fields referring to the sex of the offending teachers, the amount of the debt of each teacher, the number of occurrences in each type of infraction, in addition to the time of entry of the server at UFPA. The association of the results obtained in the two stages indicates that the University has issued adequate and sufficient norms for the regulation of all exceptions provided for by Law and, therefore, this aspect would not directly influence the occurrence of the infractions. In addition, considering the average profile of the offending teacher, it was suggested, as a product of this dissertation, the development of a booklet that would allow teachers to identify, in a simplified and summarized way, what they can or cannot do.
