In this context, the study assessed the quality of services provided by the Municipal Finance and Budget Department of Foz do Iguaçu from the users’ perspective, using the SERVQUAL scale. The research adopted a descriptive-exploratory approach with quantitative analysis, based on structured questionnaires applied to users of municipal financial services. The sample consisted of respondents selected through convenience sampling, covering different service usage profiles and levels of interaction with the digital systems offered by the Department. The collected data were subjected to descriptive and inferential statistical analyses, enabling the measurement of quality gaps between users’ expectations and perceptions across the five SERVQUAL dimensions: tangibility, reliability, responsiveness, assurance, and empathy. The results revealed negative gaps in all evaluated dimensions, indicating that users’ perceptions were below both the minimum expected and the desired ideal levels. The most significant gaps were identified in responsiveness and tangibility, particularly regarding service agility, clarity of information, system usability, and technological infrastructure. The findings provided relevant evidence to support improvements in municipal public management, guiding actions aimed at enhancing service quality and strengthening the relationship between tax administration and citizens, in addition to contributing to future academic studies in the context of municipal public administration.

This research aimed to propose a policy and a set of actions for the implementation of graduate monitoring at the Federal University of Latin American Integration (UNILA), based on current legal regulations and best practices adopted by other Brazilian federal universities. The study, of an applied nature, with a qualitative, exploratory and descriptive approach, involved the analysis of the legal framework and the institutional practices of federal universities in the implementation of policies and systems for monitoring graduates. The methodology included a document review, a Systematic Literature Review (SLR), mapping of institutional websites, and consultation with the ombudsman offices of federal universities, with content analysis of institutional responses and statistical and descriptive treatment of data collected through an applied questionnaire. The results highlight the absence of consolidated national guidelines, low standardization of procedures, technological limitations, fragility of institutional structures, and reduced engagement of alumni, revealing a scenario marked by isolated initiatives, policies under development, and diverse practices among institutions. Based on experiences considered successful, a draft institutional policy was proposed, composed of principles, guidelines, the creation of a committee, an integrated alumni portal, and management and monitoring mechanisms. This research, in addition to providing relevant information, contributes to strengthening university management, producing performance indicators, and modernizing evaluation processes, reinforcing the need for coordinated efforts to consolidate effective policies and systems for monitoring alumni within Brazilian federal universities.

This work aims to use the Theory of Constraints method to identify and mitigate bottlenecks in the building maintenance sector of a federal university, generating an increase in the efficiency and effectiveness of the services provided. The research seeks to answer how the Theory of Constraints can be applied to improve these services, analyzing its practical implementation and verifying its effects on building maintenance processes. Expected results include a significant improvement in resource allocation, reduced downtime and an increase in the responsiveness of the maintenance team. This study contributes to the literature on the applicability of TOC in educational environments, demonstrating its potential to transform maintenance management in universities Publisher: Universidade Estadual do Oeste do Paraná Tipo do documento: Dissertação Wed, 10 Dec 2025 00:00:00 GMT https://tede.unioeste.br/handle/tede/8299 2025-12-10T00:00:00Z https://tede.unioeste.br/handle/tede/8290 Title: Influência de técnicas de sincronização de conversores na distorção harmônica de microrredes Autor: Bender, Samuel Graff Primeiro orientador: Almeida, Adriano Batista de Abstract: Microgrids (MGs) are smaller-scale power systems used to integrate distributed energy resources into the main electrical grid through power converters. To ensure safe and efficient operation of these systems, both in grid-connected and islanded modes, control strategies are essential for power sharing and maintaining voltage and frequency stability. In the context of converter control, synchronization techniques, such as Phase-Locked Loops (PLLs), are employed to estimate the grid frequency and phase, ensuring the converters are synchronized with the voltage signal at their point of connection. However, these control systems are vulnerable to power quality issues, mainly voltage imbalances and harmonic distortions in the voltage signals. The presence of converters and non-linear loads are some of the causes of harmonic distortions in MGs, negatively affecting the performance of synchronization techniques. Based on the hypothesis that synchronization techniques may affect the harmonic distortion of voltage and current signals, and given the scarcity of studies regarding this problem, the present work aims to fill this gap in the literature by evaluating the dynamic behavior of synchronization techniques and their impact on the harmonic distortion of MGs. Four synchronization techniques were selected based on the literature and implemented on Digital Signal Processors (DSPs). The techniques were subjected to two types of tests: the first involved applying known signals using the UNIOESTE MG Laboratory structure, where their dynamic performance was evaluated under events of frequency and phase variation, and harmonic distortion. The second type of test was conducted via simulations in PSIM software, in which the laboratory MG model was implemented. The simulations considered the connection of a non-linear load model at different operating points and under various converter combinations. The experimental results showed that synchronization techniques with advanced filtering capabilities have better dynamic performance, ensuring robustness against grid disturbances. In the simulations, it was concluded that there is no significant coupling between the chosen synchronization technique and the harmonic distortion of the electrical quantities in the evaluated scenarios. The main contribution of this work is the verification of the hypothesis in the MG context, in addition to the development of the laboratory MG structure and the detailed computational model for future studies.
