Published: February 2025

Com o presente trabalho, delimitamos como objetivo interpretar e analisar a Nota Técnica da Resolução COFEN No 0599/2018 (Revogada pela Resolução COFEN nº 678/ 2021), documento prescritivo que orienta o trabalho do enfermeiro em serviços de saúde mental. Para tanto, lançamos olhares bakhtinianos, sob perspectiva dialógica da linguagem. Apesar de existirem algumas resoluções que monologizem o agir e engessem o trabalho do cuidar (Resolução COFEN nº 186/1995), a resolução referida, datada de 2018, convoca a pluralidade no trabalho do enfermeiro em serviços de saúde mental, principalmente na relac?a?o eu-outro. O presente estudo fundamenta-se na Análise Dialógica Discursiva (ADD), centrada na perspectiva de Bakhtin e no Ci?rculo (1988,1997, 2003, 2007, 2010) e nas teorias da Ergonomia (SCHWARTZ, 2011) – questo?es inerentes ao trabalho prescrito. Após verificação e análise do documento, constatamos que a Resolução COFEN No 0599/2018 abre espaço para relações dialógicas entre os sujeitos constituintes - trabalhadores da enfermagem. Logo, no executar de suas atividades, o enfermeiro pode fazê-la com variadas possibilidades, além de manter interações ‘discursivas’ estáveis com os outros agentes inseridos em sua atividade.
A manifestação da sombra em o Gato Preto, de Edgar Allan Poe: um estudo junguiano
Authors: Murça Amanda , Alves Biserra Wiliam
Published: February 2025

Resumo: O gato preto não é um símbolo usado primacialmente por Edgar Allan Poe, nem foi ele o último a utilizá-lo em seus recursos narrativos. Dessa forma, entende-se que o gato preto, por ter significados semelhantes em diferentes narrativas ao longo da história, constitui um símbolo representante de um arquétipo, que, para Carl Gustav Jung, é um conteúdo inconsciente presente em toda a humanidade e, por isso, esse inconsciente se chama inconsciente coletivo. Ao explorar esses conteúdos do inconsciente, encontra-se a Sombra, arquétipo que melhor representa o que a humanidade entende como mal. Sendo assim, ao analisar o discurso do narrador de O gato preto, observa-se que o comportamento do animal é reflexo ou condutor das ações malignas do indivíduo que, embora tente ignorar ou extinguir o gato, depara-se com ele até o fim da narrativa. Nesse sentido, este artigo procura dar embasamento teórico para a hipótese de que o gato preto, pertencente à narrativa supracitada, simboliza a sombra do narrador-personagem de O gato preto, de Edgar Allan Poe.

VICTOR HUGO: GÊNIO E GENIALIDADE
Authors: Silva-Reis Dennys
Published: February 2025

A noção de gênio está intimamente vinculada com o “mistério” que envolve a criação artística, pois, dentre muitas definições, ela pode ser concebida como a força criadora e, por vezes, extraordinária do artista. Muitos são os exemplos nas artes francesas e, especialmente, na Literatura. Entretanto, talvez, um dos maiores gênios da literatura seja Victor Hugo, tendo sido designado por Charles Baudelaire como “um gênio sem fronteiras”. O autor de Les Misérables, tendo consciência ou não de seu papel como gênio, escreve sobre o assunto a fim de definir o que é ser/ter um gênio artístico-literário. Sendo assim, neste trabalho visamos expor as principais ideias de Victor Hugo sobre genialidade. Além disso, pretendemos também mostrar por que alguns literatos o veem como símbolo de genialidade e como delineiam a genialidade hugoana. Isto posto, consideraremos como a discussão da genialidade em literatura não pode ser desenvolvida sem mencionar ou mesmo ter por espelho Victor Hugo.

Published: February 2025

The growing interest in solar chimneys stems from their simple design and wide-ranging applicability, offering a sustainable solution for energy efficiency and climate adaptation. However, optimizing their thermal performance in various environmental conditions remains an area of active research. This study aimed to address this gap by experimentally analyzing the thermal behavior of a solar chimney prototype with a 1-meter collector diameter in an arid climatic setting. Ten temperature sensors, evenly distributed on the absorber and collector, recorded data alongside ambient temperature and solar radiation at one-minute intervals. Results revealed that solar radiation and ambient temperature exert a significant impact on the thermal performance of the absorber and collector, with their average temperatures showing a strong correlation to these variables. A polynomial model was developed to predict the mean temperature variations of the absorber and collector as functions of solar radiation and ambient temperature, offering a reliable analytical tool for system optimization. These findings contribute to the understanding of solar chimney dynamics and provide a foundation for enhancing their design and performance, particularly in arid regions where solar energy potential is abundant.

Design, analysis, and implementation of a high-gain quasi-switched boost inverter for renewable energy applications
Authors: Hosseinpour Majid , Azimi Pooria
Published: February 2025

The increasing demand for efficient renewable energy conversion highlights the importance of advanced inverter technologies, particularly those capable of boosting DC voltage while converting it to AC. Conventional inverters face limitations in addressing challenges such as voltage stress, inrush current, and input current continuity. To address these gaps, this study introduces a modified quasi-Z-source inverter (qZSI) structure employing a quasi-switched boost inverter (qSBI). The proposed inverter achieves a high boost factor with a minimal shoot-through interval and a high modulation index, ensuring superior performance. Key features include continuous input current, reduced voltage stress on switches, and negligible input voltage ripple, along with the elimination of initial inrush current typically associated with impedance source inverters. Comprehensive operational analyses and parameter-based comparisons with similar inverters confirm the advantages of the proposed design. Experimental validation demonstrates its accuracy and effectiveness, underscoring its potential to enhance renewable energy systems through improved performance and reliability.

Design and optimization of polymer-based organic solar cells with enhanced photocurrent using plasmonic metal-metal core-shell nanoparticles
Authors: Heidarzadeh Hamid
Published: February 2025

This study explores the influence of shell thickness on photocurrent density in polymer-based solar cells incorporating gold-silver (Au-Ag) and silver-gold (Ag-Au) metal-metal core-shell nanoparticles. Efficient light trapping and absorption in polymer solar cells remain a key challenge, necessitating innovative approaches to improve performance. Addressing this gap, the research investigates how variations in shell thickness impact the plasmonic enhancement of photocurrent density. Simulations reveal that increasing shell thickness initially boosts photocurrent density due to enhanced plasmonic effects but stabilizes or declines slightly beyond an optimal thickness. For example, at a cell thickness of 80 nm, photocurrent densities of 13.74 mA/cm², 16.62 mA/cm², and 19.3 mA/cm² were achieved for the reference cell (without nanoparticles), a cell with Ag nanoparticles, and a cell with Au-Ag nanoparticles, respectively. These results underscore the critical role of shell thickness and material composition in optimizing core-shell nanoparticles for maximizing solar cell efficiency, offering insights for advancing polymer-based photovoltaic technologies.
Keywords: Core-shell nanoparticles; organic solar cell; photocurrent; plasmonic nanoparticles; polymer solar cell.

Published: February 2025

Background: Complementary feeding is crucial for children's growth and development, especially between the ages of 6 to 24 months. Adequate nutritional intake during this period can prevent long-term health issues, such as stunting and obesity. However, many mothers struggle with providing appropriate complementary feeding due to a lack of knowledge and inappropriate feeding practices.
Objectives: This study aimed to assess the effectiveness of the Emotional Demonstration (Emo Demo) method in improving maternal knowledge, attitudes, and behaviors related to complementary feeding.
Methods: Using a pretest-posttest control group design, 100 mothers with children aged 6 to 24 months were assigned to one of three groups: control (lecture), demonstration, and Emo Demo. Data were collected via questionnaires and observational assessments at multiple intervals to measure the sustainability of behavior changes. Statistical analyses, including ANOVA and Least Significant Difference (LSD) tests, revealed that the Emo Demo method significantly enhanced knowledge, attitudes, and feeding practices compared to traditional methods.
Results: The study found no significant demographic differences between groups. ANOVA showed significant improvements in knowledge, attitudes, and behavior (p-value<0.05). LSD analysis revealed significant changes in the Emo Demo group (p-value=0.010 for knowledge and behavior, p-value=0.028 for attitude), indicating its effectiveness in improving complementary feeding practices.
Conclusions: Innovative and emotionally engaging methods like Emo Demo can effectively address the challenges of complementary feeding, ultimately contributing to public health efforts to reduce stunting in Indonesia.

Published: February 2025

Background: The success of soccer athletes is influenced by physical, mental, and genetic factors, with nutritional status significantly affects youth soccer performance in Indonesia by 69.8%. Body composition and somatotype are critical components of nutritional status. Biochemical indicators such as creatine kinase (CK) and vitamin D levels provide insights into the impact of training and diet on athletes.
Objectives: To determine the effect of nutritional interventions on improving the intake and body composition of athletes characterized by the value of creatinine kinase levels and vitamin D levels of athletes and an increase in VO2 Max values as performance indicators.
Methods: This experimental study used a pre-post control trial design involving 39 subjects who were divided into treatment (20 athletes) and control (19 athletes) groups for one month. The treatment group received nutrition education (classroom, individual, and nutrition assistance) and vitamin D supplementation of 800 IU per day, while the control group was only monitored. The exercise was adjusted to the coach's program.
Results: Energy, protein, and carbohydrate intakes were deficient among athletes, although fat intake was adequate. CK levels were within normal limits. All athletes in the control group exhibited vitamin D deficiency, compared to 90% in the intervention group, despite supplementation showing modest improvement.
Conclusions: Vitamin D supplementation has a significant effect on increasing blood vitamin D levels. This study reinforces the importance of education and supplementation-based nutrition interventions to improve the nutritional status and performance of soccer athletes.

Objective: Immune checkpoint inhibitors (ICIs) have demonstrated substantial efficacy in patients with advanced non-small cell lung cancer (NSCLC). However, the optimal duration of ICI therapy remains unclear, and limited real-world data are available. The aim of this study was to evaluate the relationship between ICI therapy duration and overall survival (OS) in patients who achieved varying best overall response (BOR) during ICI treatment, and to compare patients treated for 6 to 18 months vs. at least 18 months. Methods: This retrospective cohort study included adult patients diagnosed with advanced NSCLC who received ICI therapy at the Zhejiang Cancer Hospital between 2017 and 2022. Data collection ended on May 1, 2024, and statistical analysis was performed between May and June 2024. Results: Using strict entry criteria, we screened 487 patients with advanced NSCLC and identified 134 eligible patients. Among these patients, the median durations of immunotherapy and follow-up were 24.57 months and 43.60 months, respectively. The objective response rate (ORR) was 58.2%, and the median progression-free survival (PFS) was 10.6 months. Median OS was not reached. At the last follow-up, 54 patients had no disease progression, and 118 patients remained alive. Patients treated with ICI therapy for ≥ 18 months had superior survival to those treated for 6 to 18 months (P = 0.039). Further analysis revealed that the survival benefit was associated with BOR during ICI therapy. Specifically, patients achieving complete response/partial response (CR/PR) who received ≥ 18 months of ICI therapy had a trend toward longer median OS than those treated for 6 to 18 months, but the difference did not reach statistical significance (P = 0.177). Patients with stable disease (SD) who received ≥ 18 months of ICI therapy had a statistically longer median OS than those treated for 6 to 18 months (P = 0.019). Among patients treated with ICIs for ≥ 18 months, 24 continued with ICI-based therapy and achieved a median PFS2 of 6.67 months, an ORR of 33.3%, and a disease control rate (DCR) of 83.3%. Conclusions: This study provides real-world evidence and novel insights into the need for continuing ICI therapy beyond 18 months in patients with advanced NSCLC who do not exhibit progressive disease. For patients achieving SD during ICI therapy, a treatment duration of at least 18 months appears appropriate. For patients achieving CR/PR, treatment decisions should be individualized according to patient-specific circumstances. However, owing to the retrospective study design, potential selection bias and confounding factors might have influenced the results. Therefore, our findings require further validation in prospective clinical studies.

This statement is possible based on the numerous observations that show that the intensity of the specific physical concept can influence specific elements and facts. In this way, it is possible to understand that the study is the possibility of unifying quantum physics with the theory of general relativity. The objective of the study is to help explain the elements and facts of the universe from its origins to the present.

In today’s world, where sustainable energy is essential for the planet’s survival, accurate solar energy forecasting is crucial. This study focused on predicting short-term Global Horizontal Irradiance (GHI) using data from the Southern African Universities Radiometric Network (SAURAN) at the Univen Radiometric Station in South Africa. Various techniques were evaluated for their predictive accuracy, including Recurrent Neural Networks (RNN), Support Vector Regression (SVR), Gradient Boosting (GB), Random Forest (RF), Stacking Ensemble, and Double Nested Stacking (DNS). The results indicated that RNN performed the best in terms of Mean Absolute Error (MAE) and Root Mean Squared Error (RMSE) among the machine learning models. However, Stacking ensembles with XGBoost as the meta-model outperformed all individual models, improving accuracy by 67.06% in MAE and 22.28% in RMSE. DNS further enhanced accuracy, achieving a 93.05% reduction in MAE and an 88.54% reduction in RMSE compared to the best machine learning model, as well as a 78.89% decrease in MAE and an 85.27% decrease in RMSE compared to the best single stacking model. Furthermore, experimenting with the order of the DNS meta-model revealed that using RF as the first-level meta-model followed by XGBoost yielded the highest accuracy, showing a 47.39% decrease in MAE and a 61.35% decrease in RMSE compared to DNS with RF at both levels. These findings underscore the potential of advanced stacking techniques to significantly improve GHI forecasting.

Intrduction. Studying the prevalence of anxiety, depression and insomnia among medical workers of Emergency medical service is a relevant task that will allow us to better understand the scope of the problem and develop effective strategies to support and prevent psychological problems among medical staff. Methods. A cross-sectional study was conducted with the participation of 592 medical workers employed at emergency medical service in the East Kazakhstan and the Abay regions of the Republic of Kazakhstan. The study included questions regarding socio-demographic data of the respondents, questions aimed at assessing the severity of insomnia using the Insomnia Severity Index (ISI) and questions from the HADS scale to assess the level of anxiety and depression among the participants. Results. Nearly half of healthcare workers reported symptoms of insomnia (28.2% subthreshold, 16.2% insomnia, 3.0% severe), anxiety (22.1% subclinical, 13.0% clinical), or depression (20.4% subclinical, 9.8% clinical). Feldshers (nursing staff) and those with higher education had elevated levels of these conditions. Insomnia severity strongly correlated with anxiety (r=0.539, p<0.001) and depression (r=0.415, p<0.001), emphasizing the need for targeted mental health interventions. Conclusion. The study revealed high rates of insomnia, anxiety, and depression among healthcare workers, with nursing staff and highly educated individuals most affected. Insomnia correlated strongly with anxiety and depression, highlighting the need for mental health support.
Fluctuations in Superdense and Supercritical Systems: A van der Waals Perspective
Authors: Plastino Angelo , Pennini Flavia.
Published: February 2025

We present new insights into the van der Waals (vdW) model, focusing on two key aspects: 1) the concept of maximum possible density (MPD) n=1/b, and 2) the Fano factor’s role in analyzing supercritical fluids and also in determining limits on the applicability of the van der Waals approach. Our aim in these investigations is to bridge the complexity of statistical mechanics with practical applications, targeting researchers and engineers in thermodynamic modeling and supercritical fluid systems. Our MPD, derived from the vdW excluded volume parameter b, offers a theoretical framework to explore packing constraints imposed by molecular interactions. At n=1/b, we observe a vanishing Fano factor ω, signifying suppressed particle number fluctuations. This behavior highlights the reduced configurational complexity due to geometric constraints, with implications for dense granular systems and high-pressure materials design. We use an auxiliary temperature Tw that emerges as a critical diagnostic tool, reflecting the scaling of fluctuations and bridging microscopic interactions with macroscopic stability. In supercritical fluids, we show that the Fano factor provides a sensitive parameter to detect instability thresholds near the spinodal line, revealing the intricate transitions between liquid-like and gas-like states. Our findings underscore the importance of fluctuations in modeling the nuanced thermodynamics of confined fluids and industrial supercritical reservoirs. Our results advance the vdW framework by connecting fundamental thermodynamic principles to actionable insights for practical technologies, particularly in the optimization of supercritical extraction and drying processes. This dual emphasis enhances our understanding of complex systems, marking a meaningful contribution to both theoretical and applied domains. We will see that a putative solid phase is predicted by the van der Waals equation at high densities. Importantly enough, we find that the Fano factor is able to detect the limits of applicability for the van der Waals method.
