(Centro Universitário do Estado do Pará, 2022-12-14) Negrão, Larissa Nascimento; Gomes, Vitor Hugo Freitas
The use of Virtual Reality as a tool can bring benefits to the physical and mental health of patients undergoing physiotherapeutic treatment. Its use in clinics and hospitals can provide more exciting and pleasurable care. This study aimed to develop a systematic review of the use of Virtual Reality in the rehabilitation of patients undergoing physical therapy treatment. The review focused on scientific articles chosen according to the following inclusion criteria: (1) specific search terms, (2) year of publication from 2018 to November 2022, (3) texts in English or Portuguese and (4) use of academic repositories SCIELO and LILACS. A total of 16 articles were found, and after refinement, only 8 fit the objective of the work. We concluded that Virtual Reality could increase patients' motivation, contributing to their recovery and effectiveness in the treatment of diagnoses of Parkinson's Disease, Cerebral Vascular Accidents, and patients in Intensive Care. When comparing the use of Virtual Reality with conventional physiotherapeutic intervention, the results were equivalent. Future work can deepen the object of this study because, despite observing the effectiveness of Virtual Reality, we cannot say that the approach is more effective than the conventional physiotherapeutic approach due to the scarcity of literature.

(Centro Universitário do Estado do Pará, 2022-12-12) Castro, Danilo Bezerra de; Cabral, David Santos; Borges, Oscar Waldim Simões; Melo, Ricardo Rodrigo Marinho
Technological evolution has, over the years, made life easier for everyone, regardless of the scenario. In the case of the banking environment it was no different, the impact generated by the transition to the use of technology changed many aspects of the services offered by financial institutions. However, an aspect that is not noticeable in our daily lives but is of such importance for the transformation in order to adapt to new technologies, is the development of the product, the creation process goes through several stages that many users can not even imagine they exist. The development process is based on a specific methodology, among the best known in the agile and traditional market, being agile with more current ideas and the traditional, as the name implies, older ideas however consolidated in the market. In the case of financial institutions already consolidated in the market, development based on the traditional method was widely used, until the arrival of the technological transition, where digital banks with remote services emerged, leaving the common branches, underutilized, to keep banking environments competitive. have to adapt, mainly in the sense of adopting the most current methodologies used in the market, the agile ones. Thus, this course work aims to carry out a comparative analytical case study between two projects, one agile and one traditional, carried out within the banking environment, based on metrics, evaluating the applications of the management methods employed, in order to generate a comparative report between the two methodologies.
Implementação de ambiente de baixa complexidade para sistema distribuído baseado em NGINX
(Centro Universitário do Estado do Pará, 2020) Farias, João Tomé de; Aquino, Renato Silva de; Baganha, Alessandra Natasha Alcântara Barreiros
Distributed systems foresee process decentralization and scalability, however, not always associated with increased performance and low complexity. This happens due to the difficulty of allocating processes on certain processors and complicating the implementation of the environment, recognized disadvantages of the distribution and responsible, therefore, for the underutilization of the system. The worst result, in this case, implies denying access or limiting resources to maintain the integrity of services. The search for high performance, simplicity of implementation and integrity of the solution are constant and sources of several publications in Distributed Systems. This work aims to develop a product to propose a solution for this approach, intending to optimize access, low complexity and integrity in distributed systems.

(Centro Universitário do Estado do Pará, 2022-12-05) Barbosa, Elielson Fernando do Santos; Freitas, Lucas da Silva; Lima, Pedro Augusto Pinto de; Araújo, Fábio Rocha de
Networks are structures in which there is a set of elements connected to each other and can be observed in various contexts, as seen in social or material structures designed by humanity. In view of this, society has been using discussion networks with a focus on enhancing the achievement of a concise conclusion about a given topic, discussions that have a randomness metric which evaluates the efficiency of the network interactions, with a focus on obtaining the results of the discussion networks to classify the quality of the discussion. The objective of this course work is the definition of metrics for analyzing the performance of discussion networks and the creation of an application that will allow the recording and visualization of the interactions of these networks. For this, an application was developed that records interactions during a discussion and also a server that processes this data and returns it to the application. The results obtained were an application that manages the flow of groups and discussions, in addition to also generating the randomness index and the interaction graph, duly available in the play store. This course work satisfactorily fulfilled the proposed objectives, creating metrics and satisfactory forms of evaluation discussion networks.

With an approximated expanse of 6 million km², the Amazon Rainforest is a region of global interest, particularly for its great biodiversity some of which still unmeasured. The forest exercises an important part in regional and global climate control, capturing and storing CO2, contributing with rain formation and varied biogeochemical cycles. Its large contribution to the livelihood of native and traditional communities is not to be neglected. Despite it all, the territory faces great challenges, suffering with the impacts of deforestation, fires, global climate change, pollution, and more. In its conservation efforts, the usage of advancing tools and technology has resulted in the implementation of Artificial Intelligence and its sub-areas, such as Machine Learning, which has contributed to the development of predictive studies in the Amazon. Here, we revised studies that implemented Machine Learning in the conservation of Amazon’s territory, seeking a deeper understanding of its limitations and future usage of this technology. We concluded that, as a technology Machine Learning has helped in preservation efforts, but there still is much that can be done to improve its usage, such as the utilization of comprehensive data, training of professionals and experts to adequately implement the technology and to analyze the results, being these improvements crucial to the futureconservation efforts in the Amazon Region.

(Centro Universitário do Estado do Pará, 2022) Chaves, Marcelo Calandrini; Parente, Marcos Aguiar; Silva, Matheus Lopes da; Silva, Otávio Araújo; Nascimento, Polyana Santos Fonseca
This research surveys the experiences of students of the Computer Science course at CESUPA in programming disciplines. This article aimed to analyze the way in which active teaching methodologies in these disciplines are taught from the students' perception and to verify possible barriers in their application. For this, a form was developed and distributed to students of all semesters with questions related to their experiences in the programming disciplines taught from the first to the third period of the course. After analyzing the respondents, the most used methodologies in the disciplines were identified, those that were better or worse accepted by the students, in addition to the students' experiences in the disciplines. With this, patterns of answers were observed that demonstrate some difficulties faced by the students as well as possibilities to improve the students' experience, as was the case of the use of gamification, which, according to the studies carried out, is believed to have been a differential for the software programming discipline had a good experience index, different from what happened with object programming that had a significant number of negative answers in this regard. The realization of this research could verify that, according to the students' experiences, there are obstacles in programming learning and active methodologies can either contribute positively to the student's experience in their academic development or make it difficult.

(Centro Universitário do Estado do Pará, 2020-12-07) Magnenti, Álvaro Somensi; Souza, Vitor Henrique Moreira de; Gomes, Vitor Hugo Freitas
Belém has more than 400 years of history, and several "marks" of this trajectory can be found in the city's monuments. Monuments tell an important part of the local history, and for that reason, they are fundamental to understand how Belenense society was formed. However, these milestones are falling by the wayside due to a lack of information about them. This factor contributes to residents and visitors do not enjoy this historical heritage of the capital of Pará. Therefore, this work aims to create a mobile application capable of identifying the monuments of Belém and informing the user about them, simply and quickly, helping the preservation and appreciation. During the development of this project, it was observed the difficulty in obtaining the necessary information regarding the monuments located in Belém. Therefore, a data survey was carried out. Also, using MongoDB, Spring Boot, React Native and QR Code, it was possible to develop a mobile app that is easy to maintain and scale. This work seeks a new way to allow a technological immersion in the city's history.
