This study conducts a review of several articles inside the context of railroads, where the life cycle assessment methodology (LCA) is applied. Using the ProKnow-C methodology, seven review and 85 original papers applying the LCA methodology to railroads are analyzed, and several important gaps were identified, mainly concerning the lack of disclosure of information about parameters, software and other important decisions made during the works that would allow other researchers to replicate the results in order to compare them to other railroads or different circumstances. Currently, there are no ISO standards addressing the LCA of railroads, so this work seeks to provide an initial set of guidelines for such a norm, thus facilitating the elaboration of such a norm and providing support and direction for researchers in the field until a norm can be established.

Detecção de transtorno mental via EEG, microestados e redes neurais de grafos
(Universidade Federal do Espírito Santo, 2025-05-27) Candeia, Daniel Ribeiro; Ciarelli, Patrick Marques ; https://orcid.org/0000-0003-3177-4028; http://lattes.cnpq.br/1267950518719423; https://orcid.org/0009-0001-4427-7496; http://lattes.cnpq.br/2696632870728316; Côco, Klaus Fabian ; https://orcid.org/0000-0001-7793-0693; http://lattes.cnpq.br/1374499533178055; Tello, Richard Junior Manuel Godinez ; https://orcid.org/0000-0003-1428-0990; http://lattes.cnpq.br/3966230569744918
Electroencephalogram (EEG) is a non-invasive and cost-effective technique widely used to study brain activity and diagnose neurological disorders. However, visual analysis of EEG signals is complex and requires expertise, highlighting the need for automated diagnostic support systems. In this context, this study proposes a graph-based neural network model for detecting mental disorders using EEG signals, leveraging microstate analysis. The proposed model integrates graph neural networks (GNNs) with microstate analysis, which captures transient and stable patterns of brain activity. The TUH Abnormal EEG Corpus (TUAB) dataset, containing normal and abnormal EEG signals, was used. The process included the extraction of microstates, the construction of graphs based on Spearman correlation between EEG channels, the extraction of features from EEG signals, and the application of Principal Component Analysis (PCA) to reduce the dimensionality of these features. Three GNNs were trained, each associated with signals from each microstate, and their outputs were combined using an ensemble technique. The final model achieved an accuracy of 97.46% on the test set, outperforming existing results of methods in the literature. The results highlight the effectiveness of the proposed approach, demonstrating the potential of GNNs and microstate analysis for detecting mental disorders from EEG signals

Conducted at the Aflordízio Carvalho da Silva State School of Elementary and Secondary Education, located in the neighborhood of Penha in Vitória (ES), and using Paulo Freire's contributions as a theoretical reference, this research investigates how philosophy teaching can awaken dreams in high school students from a school on the outskirts of the city, in the face of the challenges imposed by the neoliberal educational model. Its objectives were: to highlight the inhibiting effects of critical thinking, resulting from the implementation of educational neoliberalism in Espírito Santo; to investigate, in Paulo Freire, the foundations of a critique of this system; and to adapt the methodology of Culture Circles to the teaching of Philosophy as a practice aimed at awakening dreams, with a view to improving a critical reading of reality in the peripheries of Greater Vitória. The Culture Circles were held with students from five 1st year high school classes, with the aim of identifying their “limit situations” in the Territory of Good, based on the issue of dreams. These narratives were decoded through meetings with leaders and participants from movements and collectives active in the communities, who presented the students with projects aimed at transforming their reality. From these meetings, the generating theme emerged: “It is impossible to exist without dreams.” This theme guided the cultural synthesis, which took the form of slam poems and graffiti. The experience proved to be an authentic and viable first, demonstrating that philosophy teaching, anchored in a Freirean perspective, can promote a critical, humanizing and liberating education in the peripheries of Greater Vitória, connecting in a significant way to the social practices and artistic expressions - such as poetry and graffiti - that traverse and animate these realities

Science, Technology, and Society (STS) Education adopts an interdisciplinary perspective and seeks to understand the social dimension of science and technology, as well as their environmental, political, economic, ethical, and cultural implications, providing support to rethink teacher education and contribute to the articulation between theory and practice. In this context, the integration of the STS perspective into undergraduate teacher education programs can foster the development of more contextualized and reflective pedagogical practices. Considering these aspects, the general objective of this research was to analyze how Science, Technology, and Society (STS) Education is present in the initial teacher education program in Biological Sciences at UFES/Alegre, based on the analysis of curricular documents and the perceptions of students and professors of the course. Thus, the conception of science adopted in this study is that of a social and historical practice, not neutral, oriented by values and interests that permeate the entire process of knowledge production (Lacey, 2010). The conception of technology, in turn, is understood as a social construction, conditioned by systems that involve values, power, and culture, shaping lifestyles and being guided by the objectives of society (Feenberg, 2010). The Latin American Thought on STS (PLACTS) emerges in this context as a movement that seeks to reframe STS studies by incorporating the historical, social, and cultural specificities of Latin America. In the Brazilian case, PLACTS dialogues with the conceptions of Paulo Freire, complementing them within a critical and emancipatory perspective. In methodological terms, this is a qualitative case study, in which data were produced by means of document analysis and semi-structured interviews, and analyzed by means of content analysis supported by Strieder (2012) and Strieder and Kawamura (2017) STS Reference Matrix. The results indicated that the STS perspective is not explicitly materialized in the Political-Pedagogical Project (PPC) of the Biological Sciences undergraduate program at UFES/Alegre, appearing only indirectly. Participants’ perceptions were situated at intermediate and minimally critical levels regarding science and technology, in addition to highlighting the predominance of theoretical over practical training components in the course. Therefore, it is emphasized the need to make the presence of the STS perspective more explicit in the curriculum, articulating theory and practice so as to reflect on initial teacher education and on the future work of Biology teachers. The findings also highlight the importance of future research that, in addition to the theoretical dimension, promotes practical experiences with preservice teachers, in order to bring the STS perspective closer to teaching practice

Road running is one of the most practiced sports in Brazil, and in recent years it has shown an increase in the number of participants over the age of 60. The existing literature relating aging to running demonstrates that differences in movement patterns between younger and older adults are mainly associated with spatiotemporal gait parameters. Biomechanical and cognitive changes resulting from aging affect the motor pattern in older adults, which may influence sports performance. Dual-tasking is present in daily activities, whether in simple or complex tasks, and is also common during running. Performance in carrying out dual tasks is related to the individual’s cognitive and motor capacities, which are reflected in their functional performance and are impacted by aging. However, there are still gaps in the literature regarding the influence of motor and cognitive dual-tasking during running in older adults. Understanding the differences in running patterns among older adults, as well as the motor adjustments present when performing dual tasks during running, may be useful to verify whether age-related motor changes interfere with injury risk in this sport. Investigating different age groups, including middle-aged adults, can help identify whether running pattern alterations associated with dual tasking and aging already begin in this age range. The aim of this study was to investigate the kinematic parameters of the running pattern under dual-task conditions (motor and cognitive) in older adults. The study included 15 young adult runners aged 21 to 35 years, 15 middle-aged runners aged 38 to 50 years, and 15 older adult runners aged 60 years and older, all capable of performing the experimental task. Participants were instructed to run on an athletics track at a speed determined by an aerobic fitness test, under three experimental conditions: (1) Control, in which only running was performed; (2) Motor dual-task, in which the secondary task of grabbing a cup of water was added; and (3) Cognitive dual-task, in which the secondary task of solving a subtraction arithmetic problem was added. For the kinematic analysis of the experimental conditions, two digital cameras (GoPro, Hero 7 Black model) recording at 120Hz were used. The dependent variables analyzed were stride length, stride width, stride duration, and stride velocity, as well as knee and ankle angular variables. Older adult runners showed differences compared to young and middle-aged runners, with shorter stride length and stride duration, and reduced knee and ankle range of motion. No differences were found between middle-aged and young adults, which may suggest that running practice mitigates the effects of aging on running parameters. Both motor and cognitive dual-tasking interfered with most of the variables analyzed, such as decreased stride length, increased stride width, and reduced knee and ankle range of motion, with a trend toward greater interference from motor dual-tasking. An interaction between motor dual-tasking and stride was also identified, with changes observed in the stride preceding and during the motor dual-task stride, such as reduced velocity and knee and ankle range of motion. Based on these results, it can be concluded that older runners differ from young and middle-aged adult runners, what was evidenced by the changes in spatiotemporal and angular variables during dual-task running in older adults. Furthermore, it is also concluded that dual-tasking interferes with running patterns, as demonstrated by the changes above, showing that the division of attention whether in motor or cognitive dual tasks is responsible for altering motor responses during locomotion according to task demands. Finally, it can be concluded that the demonstrated changes related to the stride prior to and during the execution of the motor dual task reveal a pattern of anticipatory locomotor adjustment in the approach phase of the dual task, characterizing a motor adaptation to accommodate the task and perform it successfully. Thus, older adults may be more exposed to the risk of injury or falls as a result of aging, and their motor response and adaptation capacity to dual-task running may be compromised due to degenerations in the sensory, neuromuscular, musculoskeletal, and joint systems. Thus, the findings of this study may help fill the gap in the literature regarding the analysis of spatiotemporal and angular parameters of running under dual-task conditions in older adults. Furthermore, these results may be useful for the planning and prescription of training programs for older runners, aiming at fall and injury prevention, performance improvement, and longevity in the practice of running.
