Este estudo tem como objetivo avaliar o papel dos administradores na transmissão de cultura e valores em escolas primárias rurais da República Centro-Africana (RTNC). Os dados foram coletados por meio de entrevistas semiestruturadas com 10 administradores durante o ano letivo de 2024-2025 e analisados por meio de análise descritiva. Os resultados mostram que, embora os administradores estejam cientes dos conceitos de cultura e valores, alguns os percebem como um todo unificado. Embora a educação cultural e de valores seja considerada importante, o evento “Dia da Cultura do Chipre” é o método mais utilizado. As áreas rurais são vistas como vantajosas para a transmissão cultural, e os desafios podem ser enfrentados motivando professores e alunos.
This study embarks on a comprehensive investigation of the effectiveness of repetitive transcranial direct current stimulation (tDCS)-based neuromodulation in augmenting steady-state visual evoked potential (SSVEP) brain-computer interfaces (BCIs), alongside exploring pertinent electroencephalography (EEG) biomarkers for assessing brain states and evaluating tDCS efficacy. EEG data were garnered across three distinct task modes (eyes open, eyes closed, and SSVEP stimulation) and two neuromodulation patterns (sham-tDCS and anodal-tDCS). Brain arousal and brain functional connectivity were measured by extracting features of fractal EEG and information flow gain, respectively. Anodal-tDCS led to diminished offsets and enhanced information flow gains, indicating improvements in both brain arousal and brain information transmission capacity. Additionally, anodal-tDCS markedly enhanced SSVEP-BCIs performance as evidenced by increased amplitudes and accuracies, whereas sham-tDCS exhibited lesser efficacy. This study proffers invaluable insights into the application of neuromodulation methods for bolstering BCI performance, and concurrently authenticates two potent electrophysiological markers for multifaceted characterization of brain states.
To develop high quality cookies, even seemingly smallest changes depended on factors that can affect taste, texture, and nutritional value. In this light, this study aimed to investigate the upshot of refined wheat flour and pumpkin seed flour on properties of cookies such as antioxidant activity, thermal and oxidative stability. In view of the foregoing, the roasted pumpkin seeds of particle size below 500 μm were blended with wheat flour at different ratios (BR) to bake at selected pre-determined temperatures (T) and time durations (TD). The synergetic effect of aforesaid parameters on cookie development, BR, T, and TD was studied by varying the parameters between the range 6–15 %, 180–200 °C and from 8 to 12 min, respectively, for the baking process of cookies. Further, the process was modelled and scrutinized using numerical optimization to achieve a highly acceptable product. On that account, it was deduced that the optimal condition for BR, T, and TD were 12.87 %, 186 °C and 9.5 min, respectively, that could pave to beget the excellent quality cookies with overall acceptance score of 8, protein content 14.28 %, fat 17.85 %, ash 2.23 %, moisture 2.46 %, fiber 2.38 % and total color difference 12.01. The optimized cookies (OCs) were found to have higher protein (11.49–14.28 %), fiber (0.93–2.41 %), ash (2.19–1.77 %), total antioxidant activity (38.7158–43.1860 %), oxidative stability (28.61–51.24 h), Zn (1.42–2.63 mg/100g), and Fe (2.12–3.20 mg/100g) content as compared to the control. Laconically, the study results provided the optimized processing condition for developing high quality cookies with respect to improved nutritional value and comparable overall acceptability.

Fraction is considered one of the main topics in mathematics in the early years. Many students struggle to progress in fractions in the classrooms and on exams. Teaching strategies are among the most important factors affecting student learning of fractions. The objective of this study was to examine the effectiveness of virtual and concrete manipulatives for teaching and learning fraction addition and subtraction to fifth-grade students in selected private schools in Abu Dhabi in the United Arab Emirates. The study employed a quasi-experimental approach in which 81 students (40 male and 41 female) in four groups of grade-five participated in the pretest, intervention, and posttest. The intervention was provided by teaching fraction addition and subtraction by using concrete and virtual manipulatives. Inferential statistics such as Wilcoxon Signed Ranked test, Mann-Whitney U test and Kruskal Wallis test were employed. The results indicated that student achievement in learning fractions using concrete manipulatives was better than virtual manipulatives. Also, girls’ progress in learning fractions was more significant than boys. The findings of this study could help mathematics education by enhancing teaching strategies that have significant implications for improving students’ fraction computation skills.

Diabetic foot syndrome (DFS) is a dangerous complication of diabetes mellitus. Despite numerous studies dedicated to the wound healing process in patients with diabetic foot syndrome, surgeries in this pathology are often accompanied by surgical suture failure due to insulin therapy and require repeat surgical intervention. The aim of this study is to analyze the biochemical mechanisms involved in the wound healing process in patients with diabetic foot syndrome. To achieve this goal, articles from foreign databases such as PubMed, MedLine, Google Scholar, and the Russian Index of Scientific Citation (RISC) were selected and analyzed for the period from 2017 to 2023. The search was conducted using keywords such as diabetic foot, wound healing, molecular mechanisms, and their Russian equivalents. A total of 74 publications were identified through the literature search, of which 24 literature sources from 2017 to 2023 were included in the review, corresponding to the direction and purpose of the study. In addition, 18 sources older than 2017 were used to reveal the subject of the study from the references in the literature lists. The literature review discusses various factors that influence the wound healing process: the function of the skin barrier, activity of immune system components, as well as the contribution of hypoxia and endothelial dysfunction to tissue regeneration mechanisms in patients with DFS. Despite the available literature data, it is advisable to search for new factors involved in the development mechanisms of DFS to prevent complications and increase the effectiveness of treatment.
Abstract Background In recent years, stimulant use has increased among persons who use opioids in the rural U.S., leading to high rates of overdose and death. We sought to understand motivations and contexts for stimulant use among persons who use opioids in a large, geographically diverse sample of persons who use drugs (PWUD) in the rural settings. Methods We conducted semi-structured individual interviews with PWUD at 8 U.S. sites spanning 10 states and 65 counties. Content areas included general substance use, injection drug use, changes in drug use, and harm reduction practices. We used an iterative open-coding process to comprehensively itemize and categorize content shared by participants related to concurrent use. Results We interviewed 349 PWUD (64% male, mean age 36). Of those discussing current use of stimulants in the context of opioid use (n = 137, 39%), the stimulant most used was methamphetamine (78%) followed by cocaine/crack (26%). Motivations for co-use included: 1) change in drug markets and cost considerations; 2) recreational goals, e.g., seeking stronger effects after heightened opioid tolerance; 3) practical goals, such as a desire to balance or alleviate the effects of the other drug, including the use of stimulants to avoid/reverse opioid overdose, and/or control symptoms of opioid withdrawal; and 4) functional goals, such as being simultaneously energized and pain-free in order to remain productive for employment. Conclusion In a rural U.S. cohort of PWUD, use of both stimulants and opioids was highly prevalent. Reasons for dual use found in the rural context compared to urban studies included changes in drug availability, functional/productivity goals, and the use of methamphetamine to offset opioid overdose. Education efforts and harm reduction services and treatment, such as access to naloxone, fentanyl test strips, and accessible drug treatment for combined opioid and stimulant use, are urgently needed in the rural U.S. to reduce overdose and other adverse outcomes.
AIM The aim of this study was to investigate the relationship between the mental health of Turkish nursing students and the stress experienced during their education, their ways of coping, self-esteem, social support and individual factors. BACKGROUND Studies on nursing students have shown that students who were not in possession of effective coping strategies were at risk of presenting psychiatric symptoms when under stressful conditions. METHODS This was a cross-sectional, case-control study. The sample consisted of 516 nursing students who were studying in an undergraduate program in Turkey. Participants provided data on sociodemographic characteristics by completing the Nursing Education Stress Scale, Coping Behavior Inventory for Nursing Students, Multidimensional Scale of Perceived Social Support, Rosenberg Self-Esteem Scale, and the General Health Questionnaire. RESULTS The main factors which were considered to affect the mental health of nursing students, including "total stress" and "self-esteem" scores, "general health" evaluation, "satisfaction with school life" and "presence of a negative event within the last year", were included in all models of the General Health Questionnaire analysis. Analysis of the data indicated that these factors had strong relationship with mental health of the nursing students. DISCUSSION It is recommended that the mental health of students be monitored throughout the nursing education period and that preventive practices should be established in order to forestall mental health problems amongst nursing students. CONCLUSION The stress levels of nursing students should be monitored in order to facilitate their ability to cope with stressful situations during their training, and components for coping with stress should be included in the curricula of nursing departments.

Introduction An institution-wide protocol for uncomplicated acute appendicitis was created to improve compliance with best practices between the emergency department (ED), radiology and surgery. Awareness of the protocol was spread with the publication of a smartphone application and communication to clinical leadership. On interim review of quality metrics, poor protocol adherence in diagnostic imaging and antimicrobial stewardship was observed. The authors hypothesised that two further simple interventions would result in more efficient radiographic diagnosis and antimicrobial administration.Materials and methods Surgery residents received targeted in-person education on the appropriate antibiotic choices and diagnostic imaging in the protocol. Signs were placed in the emergency and radiology work areas, immediately adjacent to provider workstations highlighting the preferred imaging for patients with suspected appendicitis and the preferred antibiotic choices for those with proven appendicitis. Protocol adherence was compared before and after each intervention.Results Targeted education was associated with improved antibiotic stewardship within the surgical department from 30% to 91% protocol adherence before/after intervention (p<0.005). Visible signs in the ED were associated with expedited antimicrobial administration from 50% to 90% of patients receiving antibiotics in the ED prior to being brought to the operating room before/after intervention (p<0.005). Diagnostic imaging after the placement of signs showed improved protocol adherence from 35% to 75% (p<0.005).Conclusion This study demonstrates that smartphone-based applications and communication among clinical leadership achieved suboptimal adherence to an institutional protocol. Targeted in-person education reinforcement and visible signage immediately adjacent to provider workstations were associated with significantly increased adherence. This type of initiative can be used in other aspects of acute care general surgery to further improve quality of care and hospital efficiency.

The objective of the current study was to examine the impacts of rice straw and garbage enzyme generated from local vegetable and fruit waste on plant growth and carbohydrate or ammonium extraction from paddy soil after one month of growth in a pot experiment. Samples of topsoil were obtained from a depth of 0-15 cm, and the following treatments were applied: control (10 g soil), RS (adding 30 g soil + 0.6 g rice straw), GE (30 g soil + garbage enzyme), and combination (adding 30 g soil+ rice straw and garbage enzyme) maintained at room temperature. The study findings indicated that there were no observable impacts of rice straw and garbage enzyme application on biomass. However, RS addition seems to reduce root length but enhance shoot length. Soil carbohydrates that were extracted ranged from 61 to 207 mg kg−1 soil, and treatments with rice straw addition exhibited significantly higher levels compared to those without it (p < 0.05). The ammonium content was low. It could be concluded that at the initial seedling stage, rice straw has more effects on soil properties and plant growth than garbage enzyme. To fully assess the effects of rice straw and garbage enzyme on soil properties and plant growth, it is recommended that further research be conducted over longer periods
