Relação entre comprometimento motor de membro inferior e estratégias biomecânicas utilizadas durante atividades de mobilidade em indivíduos pós-acidente vascular encefálico
Authors: Lima Luma Amendoeira Almeida , Aguiar Larissa Tavares , Faria Christina Danielli Coelho de Morais
Published: August 2023

RESUMO O comprometimento motor e a limitação da mobilidade são frequentemente observadas em indivíduos após o acidente vascular encefálico (AVE) e estão associadas à dependência funcional e à baixa percepção da qualidade de vida. Portanto, é preciso investigar a relação do comprometimento motor e as estratégias biomecânicas utilizadas por indivíduos pós-AVE na realização de atividades de mobilidade. O objetivo deste estudo foi avaliar a correlação entre o comprometimento motor de membro inferior, avaliado pela seção motora da escala de Fugl-Meyer (EFM), e a mobilidade de indivíduos pós-AVE considerando as estratégias biomecânicas avaliadas pelo teste timed “up and go” assessment of biomechanical strategies (TUG-ABS). Trata-se de um estudo transversal exploratório, no qual participaram 100 indivíduos na fase crônica pós-AVE, com média de idade de 55,02±12,57 anos. Foi utilizada a EFM para avaliação do comprometimento motor de membro inferior e o teste TUG-ABS para avaliação da mobilidade durante as atividades de sentado para de pé, marcha, giro e de pé para sentado realizadas sequencialmente. Foi realizada a correlação de Spearman para verificar a relação entre as variáveis (α=5%). O comprometimento motor de membro inferior e a mobilidade considerando as estratégias biomecânicas adotadas por indivíduos pós-AVE durante as atividades propostas apresentaram correlação significativa (p<0,001), positiva e de moderada magnitude (rs=0,60). Isso indica que o comprometimento motor é um desfecho importante para se considerar no processo de reabilitação de indivíduos pós-AVE que apresentam limitações de mobilidade como as avaliadas pelo TUG-ABS.

ABSTRACT Objective: To identify and describe the mental health training programs for non-health professionals and volunteers who work, have worked, or would work with asylum seekers and/or refugees. Method: Scoping review following JBI methodology. Search carried out in MEDLINE, CINAHL, ERIC, SCOPUS, PsycINFO, Psychology & Behavioral Sciences Collection, RCAAP, ProQuest, and websites of Clinical Trials, UNHCR, International Organization for Migration, WHO, Save the Children, International Migration, Integration and Social Cohesion in Europe, and International Federation of Red Cross and Red Crescent Societies. Studies written in English, Portuguese, French, Spanish and Swedish. Results: Of the 8954 articles identified, 16 were included reporting on 11 training programs: Mind-Spring, PM+, MHFA, Cognitive-Behavioral Training for Community and Religious Leaders, EmpaTeach, Suicide Prevention Education Program, Teaching Recovery Techniques, Handbook for Teachers of Vietnamese Refugee Students, PFA, Psychosocial support of volunteers and CBP&MHPSS. Conclusion: Training programs from scientific literature focus on mental health disorders, while non-governmental organizations’ documents focus on resilience and self-care. The current mental health training programs might be insufficient.

ABSTRACT Objective: To verify the association between sociodemographic, clinical, environmental, cognitive, and emotional factors and the decision time of people with ischemic stroke to seek a health service after the onset of symptoms or wake up stroke. Method: Cross-sectional study carried out from March to October 2019, with 304 patients, in a public hospital, a reference in neurology. Data obtained through interview and from medical records. Decision time was analyzed as a geometric mean. In the bivariate and multivariate analyses, linear regression was used and the Akaike Information Criterion was used to select the best model. Statistical significance of 5% was adopted. Results: The geometric mean of decision time was 0.30h (95% CI 0.23–0.39). The final model explained this time in 41%, showing an increase of 0.5 min for people with arterial hypertension; 10.8 min for those who waited for symptoms to improve; 1.4 min for those who were alone at the onset of symptoms; 3.9 min for those at home; 3.2 min for the ones at work; and 2.1 for those on the street/public space. Conclusion: The mean decision time for seeking a health service was high and influenced by clinical, environmental, cognitive, and emotional variables. The results guide nurses regarding health education.

Published: August 2023

ABSTRACT Objective: To understand nursing team professionals’ strategies to include the family in painful procedures performed on hospitalized children. Method: An exploratory-descriptive, qualitative study, carried out with nursing professionals. Data were collected through semi-structured interviews, guided by a script of topics, transcribed and submitted to thematic content analysis, in the light of Symbolic Interactionism, discussed considering the Family-Centered Care philosophy assumptions. Results: Two central categories emerged, “Theoretical perspective: the family as a care agent in painful procedures” and “Practical perspective: experiences, challenges and strategies in painful procedures for family inclusion”, with their respective subcategories. Conclusion: Nursing professionals have theoretical knowledge about family inclusion in painful procedures based on the assumptions: Family-Centered Care: dignity and respect; information sharing; joint participation; and family collaboration. However, knowledge is not applied in clinical practice; consequence of the interaction between beliefs and attitudes unfavorable to family presence.
Psychoeducational module on Neurocognitive impairments – Mild and Severe. Module of the neuropsychological intervention program for the elderly, REHACOG
Authors: Figueira Ana Paula Couceiro
Published: August 2023

Abstract Objective The purpose is to present a neuropsychological intervention program, aimed at the broader person, the Psychoeducation Module, directed fundamentally at one’s support network, family members and even intervention agents. Method The Cognitive Rehabilitation Program, given the acronym REHACOG, can work as a remedial and/or preventive tool that is very structured but flexible and complete because it includes varied tasks that promote multiple cognitive, linguistic and socio-emotional processes. REHACOG has an active character, also having a module more oriented to information and awareness for all the themes inherent to the larger individuals, potentially more oriented to caregivers or the elderly support network. Results Emphasizing this last topic, which has not yet been disseminated, which is the main objective of this article, we present the training module and the psychoeducational module, which includes six rubrics that cover topics ranging from conceptualization(s) of dementia, neurocognitive disorders, to symptomatology, assessment, intervention, caregivers and their roles, and response resources. Conclusion Although this material has not yet been published and disseminated, we expect to use and test it very soon.We look forward to its usefulness among professionals and future professionals in the area.

ABSTRACT This study aimed to evaluate the efficiency of the parameters fresh leaf mass and stomatal density in the estimation of ploidy and pre-selection of putative banana autotetraploids. Young plants of the diploid cultivar Ouro (AA), previously subjected to in vitro polyploidization with the antimitotic amiprofos-methyl - APM (0, 10, 20, 30, 40, and 60 µM L-1) and colchicine (2.5 mM L-1) were evaluated for survival, height, number of leaves, pseudostem diameter, leaf disc fresh mass, and stomatal density. Ploidy was determined by flow cytometry in a random sample of 200 plants to find the relationship between the genomic content and the analyzed variables. Spearman’s correlation analysis showed a strong correlation (0.84**) between leaf disc fresh mass and tetraploid plants, as well as an absence of significant correlation between stomatal density and ploidy levels. Thus, the pre-selection of plants was carried out using a reference value of leaf disc fresh mass and resulted in 688 plants pre-selected as putative tetraploids. Among them, 318 were confirmed as tetraploids, 291 as diploids, and 79 as mixoploids after flow cytometry analysis. The pre-selection efficiency was 46.2% of tetraploid plants from the total pre-selected. The results indicate that the use of leaf disc fresh mass is a simple, practical, and promising method to estimate ploidy when a high number of plants is obtained in in vitro banana polyploidization studies, reducing the total number of plants to have confirmed ploidy.

Published: August 2023

ABSTRACT The production of healthy pineapple seedlings for commercial plantations has been one of the main limiting factors of the species, and the search for improvements to meet this demand has been constant. Therefore, the present study aimed to compare different propagation strategies (natural tillering, stem sectioning, and micropropagation) in three commercial cultivars 'BRS Imperial', 'Pérola', and Gold 'MD-2' of pineapple. Three methods of vegetative propagation were evaluated: conventional, stem sectioning, and micropropagation. The evaluations consisted of the number of seedlings produced by each method and the period for their development until planting in the field. According to the conventional propagation technique results, the young seedling type in the cultivar 'Pérola' was more abundant. In the propagation by sectioning the stem, the 'BRS Imperial' cultivar presented the highest number of seedlings. Regarding the micropropagation technique, the highest production of shoots was observed in the third subculture for all cultivars, especially for ‘BRS Imperial’, which presented the highest total number of shoots in all subcultures. It was concluded that the micropropagation technique proved efficient in producing uniform seedlings on a large scale, in addition to having an advantage in the greater number of seedlings produced compared to the other methods studied.

ABSTRACT The production of seedlings of forest species for reforestation of biomes is a practice that restores the conditions of the environment, but water and substrates that favor the growth of seedlings are required. However, in the semi-arid region, water is a limiting factor, requiring the use of alternative sources such as treated domestic sewage. In this context, the objective was to evaluate the growth of Anadenanthera colubrina L. seedlings produced in substrates (soil + bovine manure and soil + coconut fiber) fertilized with treated domestic sewage effluent diluted in public-supply water in proportions (100, 75, 50 and 25% of domestic effluent) and using water from the supply network as a control. The treatments were arranged in a completely randomized design, in a split-plot with three replicates. The treated domestic effluent (TDE) used in the experiment came from the domestic sewage treatment plant of the decanter-digester type of the Projeto de Assentamento Milagre Apodi/RN. The study was conducted in a seedling production nursery at UFERSA, with growth and vigor evaluations at 30, 60, 90 and 120 days after transplanting. The production of seedlings fertigated with domestic effluent caused differences in all growth variables, with improvement in phytomass production. Seedlings fertigated with a dilution of 50% TDE and 50% water supply showed better results when produced with substrate composed of soil and coconut fiber. The seedlings showed good quality, and those cultivated with 50% and 75% of wastewater showed better quality after 120 days of cultivation.

Published: August 2023

ABSTRACT The federal public agencies have prioritized the financing of underground dams as a strategy to decrease water scarcity in rural semiarid regions in Brazil. The objective of this work was to evaluated water quality in underground dams, for agricultural irrigation purposes, in Rio Grande do Norte, Brazil, at the end of the dry season in 2018 and at the end of the rainy season in 2019. The variables with the greatest impact on water quality were identified through multivariate analysis, using the software Statistica 7.0. The results showed that concentrations of variables correlated with salinity and ion toxicity in water of the dams decreased after the rainy season, whereas those correlated with clogging of localized irrigation systems increased. Salinity, sodicity, and/or toxicity in areas of underground dams were correlated with natural mineralization of geological components of soils; however, they also were affected by rainfall with marine hygroscopic nuclei, presence of rural clusters and corrals, and decomposition of organic matter in the damming area. The variables correlated with salinity presented higher effect on the hydrochemical variability of water within these dams in both sampling periods; electrical conductivity and chloride ions were the most significant variables.

ABSTRACT Cowpea is a socioeconomically important legume in the Northeast region of Brazil, and the most grown and consumed type of bean, representing the main source of low-cost vegetable protein for rural and urban populations in this region. The objective of this work was to characterize the proximate composition, minerals, tannins, phytic acid, and cooking quality of whole grains of cowpea from the commercial cultivars BRS Aracê, BRS Inhuma, and BRS Xiquexique. Grain samples of the cultivars were ground in a zirconium ball mill and the flour was used for analysis. The proximate composition was carried out according to the AOAC methodology. The minerals were determined by nitro-perchloric digestion and reading in a flame atomic absorption spectrophotometer. The anti-nutritional factors tannins and phytic acid were determined by extraction and reading in a spectrophotometer. Cooking quality was assessed using an electric pressure cooker and then a Mattson cooker. A completely randomized experimental design was used, with three treatments (cultivars) and three replications. The data were subjected to analysis of variance and the means were compared by the Tukey's test (p<0.05). The cowpea cultivars showed significant differences (p<0.05) for most characteristics evaluated and were similar in terms of ash, lipids, total dietary fiber, and most macrominerals. The results showed that grains of the cultivars BRS Aracê and BRS Xiquexique are excellent sources of dietary fiber, proteins, and minerals and present high cooking quality, while grains of the cultivar BRS Inhuma stood out regarding carbohydrates, soluble dietary fibers, total energetic value, and low levels of factors, anti-nutritional tannins and phytic acid.

ABSTRACT The objective of this work was to select water deficittolerant accessions of the genus Manihot, through morphological characters under different water regimes. The experiment was conducted in a randomized block design, using a split-plot arrangement with plots consisting of tree water regimes (simulated rainfall and water depth of 100 and 20% crop evapotranspiration (ETc)), and subplots consisting of eight accessions of the genus Manihot (Gema-de-Ovo and Engana-Ladrão from the species M. esculenta Crantz, and BGMS-115, BGMS-110, BGMS-102, BGMS- 79, BGMS-24, and BGMS-48 from Manihot sp.). The accessions were evaluated considering two crop cycles: the first had 120 and 60 days from the application of the treatments. Plant height, stem diameter, number of leaves, leaf lobe length and shoot dry mass production were evaluated. For each cropping cycle, a split-plot analysis of variance was performed. The highest genotypic means were expressed by the accessions BGMS-115, BGMS-102, BGMS- 79 and BGMS-24 for most of the analyzed variables, regardless of the cultivation cycle. For the characteristic shoot dry mass production, accessions BGMS-102 and BGMS-79 showed the best performances under conditions of limited water regime (20% ETc), regardless of the cropping cycle. Accession BGMS-102 was also grouped in the group with the highest genotypic means, for this trait, in treatments with rain simulation and 100% ETc, in the first cycle, demonstrating that, under stress conditions, this accession is an option to tolerate low water precipitation and responds well when higher precipitation occurs.

ABSTRACT Objective: Considering the importance of the beginning of the academic trajectory for children to reach their full development, this work aims to evaluate the school readiness of preschool-age children and identify which factors influence these results, in order to contribute to the proposition of strategies that allow improving the teaching-learning process and child development. Methods: This is a cross-sectional, descriptive and analytical study with 443 preschool children belonging to the West Region Cohort (ROC Cohort), from the public school system of the city of São Paulo. School readiness was assessed by the International Development and Early Learning Assessment (IDELA) tool. Non-parametric techniques were used for the correlation analysis between IDELA scores and sociodemographic and socioeconomic conditions: Spearman's parametric correlation, Mann-Whitney and Kruskal-Wallis tests. Results: The children's mean age was 69 months (standard deviation — SD=2.8; ranging from 55 to 72 months) and most of them came from families with low socioeconomic level. Most children showed adequate readiness in the overall score (65%) and in most domains, except for emergent literacy, in which most (56.9%) were classified as “emergent”. The highest percentage of insufficiency was identified in executive functions (4.1%), which showed a correlation only with the caregiver's education. Conclusions: Children had adequate school readiness scores, except for emergent literacy, but the insufficiency in executive functions may compromise the future schooling of these children. Thus, pedagogical proposals should consider these aspects for learning and pediatricians need to reinforce the habit of reading and playing games to stimulate child development.

ABSTRACT Objective: To evaluate the impact of COVID-19 social distancing recommendations on nutritional status, pulmonary function, and morbidity in patients with cystic fibrosis (CF). Methods: A retrospective cohort study including patients older than six years with a diagnosis of CF was performed. Demographic and clinical data, anthropometric measurements, pulmonary function, days of antibiotic use, and length of hospital stay were recorded. Variables were recorded at three time points relative to the baseline for implementation of social distancing measures: T-1 (14 months before implementation), T0 (baseline), and T1 (14 months after implementation). Delta (Δ) was calculated for each period: Δ1 (pre-pandemic T0-T-1) and Δ2 (pandemic T1-T0). Results: The study included 25 patients, with a mean age of 11.7±4.3 years. The mean forced expiratory volume in the first second (FEV1) was 85.6±23.6%, and body mass index (BMI) was 17.5±3.0 kg/m2. When comparing the two periods (Δ1 and Δ2), there was a significant increase in the FEV1/forced vital capacity (FVC) ratio (p=0.013) and in the forced expiratory flow between 25 and 75% of vital capacity (FEF25–75%) (p=0.037) in the pandemic period. There was also a significant reduction (p=0.005) in the use of antibiotics in the pandemic period compared with the pre-pandemic period. The Δ1 and Δ2 values did not differ significantly for BMI, FEV1, or length of hospital stay. Conclusions: COVID-19 social distancing recommendations had a positive impact (decrease) on morbidity (use of antibiotics) and small airway obstruction (FEF25–75%) in patients with CF.
Sobre as Crônicas de São Denis e o Liber florum, de João de Morigny: algumas possibilidades
Authors: Fontoura Odir Mauro da Cunha
Published: August 2023

RESUMO Este artigo tem por objetivo analisar dois relatos, extraídos das Crônicas de São Denis, sobre um monge anônimo de Morigny que, na primeira metade do século XIV, supostamente praticava magia e cultuava demônios. Serão considerados os relatos das continuações da Cronica latina de Guilherme de Nangis e das Grandes Chroniques de France sobre esse tema. Essas referências são analisadas de forma comparativa em relação a outro texto, da mesma época, escrito em primeira pessoa por João de Morigny e intitulado Liber florum celestis doctrine. Essa pesquisa defende a hipótese de que o anônimo das Crônicas de São Denis é João de Morigny. O estudo comparado aqui apresentado torna possível verificar, ainda, que o que era descrito como demoníaco pelos cronistas de São Denis, segundo João, é exemplo de devoção e ortodoxia, o que remete a um espaço de contradição e disputa a respeito do que era entendido como “magia” no Medievo.
“Por terra ou por água”: os rios Tapajós e Xingu entre os planos de transporte na Amazônia do século XIX
Authors: Nunes Francivaldo Alves
Published: August 2023

RESUMO Este texto propõe recuperar os principais debates que envolveram a implantação de vias de navegação no Pará da segunda metade do século XIX, reservando um aparte para as experiências vivenciadas nos rios Tapajós e Xingu. Para isso, utilizamos um conjunto de documentação produzida pela administração provincial e do Império, assim como os anais do parlamento brasileiro. A perspectiva é compreender as ações do governo imperial como política de incentivo à migração de populações para áreas beneficiadas com essas construções, de forma a perceber os impactos sobre a ocupação e o consequente aumento produtivo, na medida em que novas áreas de cultivo e extração fossem exploradas e novas técnicas fossem conduzidas para essas regiões com o processo migratório.
Violência no trabalho: dimensões estruturais e interseccionais
Authors: Vieira Carlos Eduardo Carrusca
Published: August 2023

Resumo Introdução: a violência é um fenômeno histórico e sociocultural que acompanha a humanidade desde sua origem. Nos contextos de trabalho, a violência tem sido objeto de renovada atenção nas últimas décadas, em razão da incidência de sérios problemas que assolam os trabalhadores, tais como: os suicídios, a criminalidade e os transtornos mentais e comportamentais. Objetivo: discutir as dimensões estruturais e interseccionais da violência relacionada ao trabalho (VRT). Métodos: foi realizada reflexão teórica assentada na literatura científica. Resultados: os debates sobre a interseccionalidade permitem compreender os riscos psicossociais como resultados das interações dos trabalhadores com os imbricados processos sociais, que remetem às estruturas de poder, notadamente às relações transversais de classe, “raça” e gênero, sem prejuízo à incorporação de outros eixos de diferenciação social que importem para os sujeitos e para a análise do trabalho. Conclusão: conclui-se que a VRT não pode ser adequadamente compreendida e enfrentada sem o entendimento das suas distintas dimensões, bem como das articulações entre elas, das suas manifestações plurais e interseccionais, além de seu caráter sistêmico no modo de produção capitalista.

Published: August 2023

ABSTRACT The role of science and technology parks (STPs) in economic development, and in particular in the growth of the firms, has received considerable attention from government policies in different countries. However, there is no consensus in the literature on whether the location in these parks has positive effects on firms’ sales growth. This paper aims to extend the discussion on the effects of STPs by providing new empirical evidence. With this purpose, we use a sample of 553 Portuguese companies located in these infrastructures and a control sample of the same size. We use the Propensity Score Matching Procedure to match the samples and the analysis is carried out by the Generalized Method of Moments in dynamic panel data. The empirical analysis does not prove any statistically significant effect of the location of the firms in science and technology parks on their growth in sales.

RESUMO Os resíduos da construção civil (RCC) constituem atualmente um dos maiores problemas das áreas urbanas, sendo a gestão adequada desse material um desafio para grande parte dos municípios brasileiros. Nesse contexto, os consórcios intermunicipais surgem como uma alternativa de viabilização de projetos, com base no princípio de que a busca de parcerias pode ser uma opção mais atrativa e econômica. Dessa forma, este trabalho teve como objetivo avaliar a viabilidade econômica de três cenários diferentes para a implantação de infraestruturas de gerenciamento e reciclagem de RCC para formação de um consórcio intermunicipal nos municípios pertencentes à Bacia Hidrográfica do Baixo Pardo/Grande (UGRHI 12). Por meio das visitas e entrevistas com gestores públicos, constatou-se que nenhum dos municípios da UGRHI 12 possui infraestrutura adequada para o gerenciamento dos RCC gerados. As análises de viabilidade econômica mostraram que o compartilhamento de uma usina de reciclagem de RCC, uma área de transbordo e triagem e um aterro se mostrou o cenário mais vantajoso, resultando em uma taxa interna de retorno de 78,79%, um valor presente líquido de R$ 29.094.983,16 e payback de um ano e sete meses. Entretanto, nos três cenários analisados, viu-se que a gestão compartilhada dos RCC pode ser viável e lucrativa, podendo trazer redução de custos e ganho de escala.
Cost-benefit analysis of technological changes: case of a management solid waste consortia in the metropolitan region of Curitiba, Brazil
Authors: Túlio Tarso José , Schmitz Arno Paulo
Published: August 2023

ABSTRACT Huge increases in the volume of waste produced by society have created an urgent need for new and improved municipal solid waste (MSW) processes. In many countries, traditional methods to manage MSW, such as landfills, have been abandoned in favor of more effective and environmentally efficient technologies. These include gasification (decomposition at high temperatures), recycling, and composting (of organic matter). The purpose of this research was to assess certain financial, social, and environmental indicators, especially the IRR and cost-benefit ratio of changing the technologies used in MSW processing. The research focuses on assessing these changes in the CONRESOL area — a consortium that covers almost all the municipalities in the metropolitan region of Curitiba, Brazil. To this end, scenarios were proposed that apply various technological combinations and two collection fees. Of the three proposed scenarios, the one with the best socioeconomic and environmental results (Internal Rate of Return, Net Present Value, Discounted Payback, and Benefit/Cost ratio) combines gasification, recycling, and composting. This scenario generated the least GHG emissions and the highest number of jobs.

Published: August 2023

The efficiency of a solar water heater with a flat-plate collector, which had an absorber area of 2 m2 and utilized a cerium oxide-water nanofluid as the working medium with a fixed volume fraction of 0.01%, was analyzed using a holistic approach. To assess the impact of flow rate on its heat transfer characteristics, the working fluid was systematically circulated through a pump-circulation system at various flow rates ranging from 1 to 3 liters per minute (LPM). The system underwent analytical and field testing, which revealed that it achieves a maximum thermal efficiency of 78.2% at a flow rate of 2 LPM. The heat transfer coefficient underwent a notable enhancement, leading to a 21.5% increase in thermal efficiency compared to a system operating with plain water. A refined artificial neural network (ANN) model was created to forecast thermal performance and outlet temperature. The optimized ANN model is structured with a 3-10-2 architecture and achieves a mean squared error of 8.2 × 10-3. The performance of the optimized ANN model was assessed by testing its generalization capacity against experimental results. It was determined that the ANN model predictions aligned closely with the experimental data, exhibiting correlation coefficients ranging from 0.96 to 0.98. This study conclusively demonstrates that the analytical model and ANN can serve as a highly effective design tool for evaluating the performance of innovative solar collectors.

Authors: Li Dong , Jiang Zhenlong , Tian Kuo , Ji Ran
Published: August 2023

Six machine learning methods (linear regression, logistic regression, extreme gradient boosting (XGBoost), support vector machine, K-nearest neighbours and artificial neural network) were used to predict/classify the hydraulic conductivity of conventional sodium bentonite (Na-B) geosynthetic clay liners (GCLs) to saline solutions or leachates. Data were collected from the literature and randomly divided into two groups – that is, 80% of the data were used to train machine learning models and the rest, 20%, were applied to evaluate model performance. Features that are known to affect the hydraulic conductivity of Na-B GCLs (e.g. mass per unit area of GCLs, monovalent and divalent cations, ionic strength (I), relative abundance of monovalent to divalent cations (RMD), swell index and effective stress) were employed to predict/classify the hydraulic conductivity of Na-B GCLs. Comparative analyses were conducted with seven subsets corresponding to the combination of different features, and the best model was determined through cross-validation. The results showed that XGBoost consistently had the best performance among all methods over all subsets of features for both regression and classification analyses. Subset 4, using the swell index, I, RMD, I 2 × RMD, monovalent cations, divalent cations, effective stress and mass per unit area as features, outperformed all other six subsets in both regression analysis (R 2 = 0.826) and classification analysis (accuracy = 0.887) in the out-of-sample tests.

Authors: Wangchuk Tshering
Published: August 2023

Facebook is the most popular network site among young Bhutanese people. Students spend a substantial amount of time checking Facebook and chatting with friends, which could be detrimental to their reading habits. The aim of this study was to investigate the impacts of Facebook on the reading habits of a higher secondary school students in Bhutan. A mixed method, specifically a convergent design, was adopted for the study, and it was guided by the Pragmatism worldview. Quantitative data were gathered from 274 participants and qualitative data were collected from 10 interviewees and one focus group discussion. Participants included teachers, parents, and students from a higher secondary school in Thimphu Thromde. A descriptive and inferential statistical following thematic analysis was used for quantitative data and the qualitative data were analyzed along the same themes. The findings of the study revealed that use of Facebook positively affected students’ reading habits. Students developed positive attitudes towards reading, after they were exposed to inspiring and interesting articles. However, the study also highlighted the negative impacts of Facebook on students’ reading habits. Further, the study revealed that students have become complacent in reading owing to Facebook activities. The findings of the study may help different stakeholders understand the importance of creating awareness about media literacy to enable students to choose authentic reading materials on Facebook. This study recommends the Ministry of Education to develop policy and provide media literacy education to students to ensure they consume media information judiciously.
Radix rufescens (J. E. Gray, 1822) (Gastropoda: Lymnaeidae), a new species for Oman and Arabian Peninsula
Authors: Falniowski Andrzej , Jaszczyńska Aleksandra , Hofman Sebastian
Published: August 2023

The fauna of freshwater gastropods of the Arabian Peninsula, a desert land, is neither rich nor extensively studied. Only five species of the family Lymnaeidae have been recorded from this subcontinent so far. In February 2023, a few specimens of Radix rufescens (J. E. Gray, 1822) have been collected from the stream at Wadi Tiwi, NE Oman. The shell, female part of the reproductive organs, prostate, paraeputium and phalloteca are presented. Cytochrome oxidase subunit I (COI) sequences confirmed the assignment of these specimens to R. rufescens, known from Nepal, Bangladesh, and Myanmar, not from the Arabian Peninsula. Either R. rufescens is the sixth lymnaeid species inhabiting Arabia, or at least some of the records of R. natalensis (Krauss, 1848), whose shells are hardly discernible from the ones of R. rufescens, should be interpreted as misidentified R. rufescens. Thousands of years of the trade relations between Oman and India suggest accidental transportation of this snail by trade vessels.

Authors: Lowrie Lieu , Duncan Leah , Samuels Dustie , Elizabeth Ablah, Ph.D., MPH  , Ofei-Dodoo Samuel
Published: August 2023

Introduction. Prehospital behavioral emergency protocols provide guidance on when a medication may be necessary for prehospital behavioral emergency; however, the final decision of which medication to administer to a patient is made independently by paramedics. The authors evaluated circumstances in a prehospital behavioral emergency when paramedics considered chemical restraints, and factors that go into choosing which medications to administer.
Methods. The authors utilized a qualitative research design involving paramedics from a Midwestern County in the United States, between November 18 and 26, 2019. A total of 149 paramedics were asked to complete a survey consisting of two open-ended questions to measure their clinical decision-making process and factors considered when selecting a medication from a behavioral emergencies protocol. The authors used an immersion-crystallization approach to analyze the content of the interviews.
Results. There was a 53% (n=79) response rate. Six major themes emerged regarding the paramedics’ decision to use medication for behavioral emergencies: safety of the patients and paramedics; inability to use calming techniques; severity of the behavioral emergency; inability to assess the patient due to presentation; etiology of the behavioral episode; and other factors, such as age, size, and weight of the patient. Six major themes emerged regarding factors considered when choosing medication for behavioral emergency: etiology of the behavioral emergency, patient presentation, the patients’ history and age, desired effect and intended outcome of the medication, and other factors.
Conclusions. The findings of the study showed that EMS paramedics rely on several factors, such as safety of all parties involved and etiology of the behavioral emergency in deciding when, and which medication to use in a behavioral emergency. The findings could help EMS administrators to develop protocols that address a variety of behavioral health emergencies.
Confesiones asiáticas (Antología de cuentos 2011-2021)
Authors: Rodríguez Augusto
Published: August 2023

La escritura del narrador ecuatoriano, Augusto Rodríguez es directa, incisiva, y entra en el drama de la vida cotidiana, familiar, rutinaria en la América Latina de hoy, con sabiduría, con entereza, con un destello interesante, humano, de compasión. Jorge Edwards Estos cuentos de Augusto Rodríguez deberían llevar un aviso de alerta: Si abres este libro no podrás cerrarlo. Hoy que los lectores de este mundo sobreimpreso leen sabiendo que dejarán pronto cualquier libro, estos cuentos son una lección límpida y feliz de retener al lector hasta el final, atrapado por el cuento empezado. Este libro, además, lo sabe, y avanza, como los clásicos, “raudo pero deleitoso”. No sin humor, prolonga las estrategias retóricas de alimentar las expectativas de la lectura. Rodríguez ejerce esa proeza con el lenguaje más inmediato y, a la vez, más suficiente. Y con esa complicidad afectiva nos hace parte del trayecto narrado, como si se decidiese en la lectura la suerte de sus héroes, tan cotidianos y transparentes como el lenguaje que los enciende de certidumbre y empatía.

РЕСТРУКТУРИРОВАННАЯ ИНФОРМАЦИЯ И КОНТЕНТ В ГРАЖДАНСКОМ ОБОРОТЕ
Authors: ЭНТИН Владимир Львович

Авторское право и смежные права регулируют гражданский оборот информации, которая приобретает структурированный характер в результате интеллектуальной деятельности. Структурированная информация, которая обрабатывается в автоматическом режиме, если она не описана в терминах права интеллектуальной собственности, оказывается вне сферы его действия. Структурированная информация, в отношении которой могут быть предъявлены требования в связи с владением, пользованием или распоряжением ею, охраняется правом. Ее коммерческое использование получает моральную и юридическую оценку. Когда информация обезличена, моральная и юридическая оценки расходятся. Объекты авторских и смежных прав, независимо от того, охраняются имущественные права на них или нет, обезличиваются собирательным термином «контент». Размещение контента в интернете делает возможным его переработку без ведома правообладателя. Последствия такой переработки для создания результатов интеллектуальной деятельности естественным или искусственным интеллектом оцениваются правом. Примитивное присвоение осуждается правом и моралью. Присвоение через творческую переработку, агрегирование информации и майнинг — нет. Параллельно складываются универсальные тренды регулирования хранения и передачи личной информации, куда нередко попадают и «фейки».

Слабости технического контроля над интернет-пространством государства стремятся компенсировать юридическими средствами. Усиливается регуляторный надзор. Ужесточается ответственность за несоблюдение административных предписаний. Расширение зон регулирования информации сопровождается разработкой специализированного правового аппарата, позволяющего вовлекать в гражданский оборот различные элементы информационного пространства.
The Foundation of Evaluation and Volition on Cognition: a New Contribution to the Debate over Husserl’s Account of Objectifying and Non-Objectifying Acts
Authors: Spano Nicola
Published: August 2023

In the present article I aim to make a new contribution to our phenomenological understanding of the foundation between intentional experiences. In order to accomplish this goal, I discuss Husserl’s effort to avoid the conflation of the class of non-objectifying acts, i.e., evaluations and volitions, with the class of objectifying acts, i.e., cognitions. Through the analysis of the transition from his early to his mature account, I explore how Husserl, by readdressing the idea of foundation in relation to the shift from the practical-evaluative to the theoretical attitude, clarifies how evaluations and volitions can exert their intentionality only on the basis of a foundation on cognitions without thereby being reduced to a mere special case of founded representations.
Husserl and Non-Formal Ethics
Authors: Venier Veniero
Published: August 2023

From its very beginnings, Husserl’s philosophical life was characterised by the interweaving between ethical reflection and logical-argumentative rigour. It is not just a matter of the constant efforts that were put into a theoretical formulation that was always aimed at constant formal coherence, but also and above all, of the progressive association of a rigorous ethics with the value of the individual-personal dimension. The phenomenological analysis of the values – intertwined with those of perceptive-intellective experiences, feeling and volition – gradually find a common denominator that progressively takes shape in the ethical-non-formal theme of personal motivation.

Published: August 2023

Bu çalışmada, Amerikan Karayolları Müdürlüğü FHWA (Federal Highway Administration) tarafından geliştirilmiş bir yazılım olan DRIP (Drenage Requirement in Pavements) aracılığıyla, demir çelik endüstrisi atık malzemesi olarak ortaya çıkan çelik cüruflarının hidrolik iletkenliğinin drenaj süresi ve karayolu temel tabakasının kalınlığı üzerindeki etkisi incelenmiştir. Analizlerde üçü elektrik ark fırını (EAF), bir tanesi pota fırını (PF) cürufu olmak üzere dört farklı tesisten elde edilmiş çelik cürufu (SS), ayrıca drenaj performansının karşılaştırması ve kontrol amacıyla bir adet tabii zemin malzemesi kullanılmıştır. Drenaj yüzdesi (U), temel tabakası kalınlığı (H) ve hidrolik iletkenlik (k)’in drenaj süresi üzerindeki etkisi incelenmiş olup analizler sonucunda ince dane içeriğinin ve hidrolik iletkenliğin, özellikle drenaj süresini, drenajın %40’ı tamamlandıktan sonra önemli ölçüde etkilediği görülmüştür. Ayrıca, temel kalınlığının arttırılması, drenaj süresinde ciddi bir azalmaya neden olmaktadır. Kontrol malzemesi ile farklı tesislerden elde edilmiş çelik cürufu malzemesinin performansları karşılaştırıldığında, özellikle elektrik ark fırını çelik cürufu malzemelerinin drenaj özelliklerinin yol dolgusu malzemesi olarak kullanımında tatmin edici sonuçlar verdiği gözlemlenmiştir.

Published: August 2023

Sandwich material panel is a structure made from three layers. A low density core is inserted in between two relatively thin skin layers. This sandwich material is used to achieve excellent mechanical performance at minimal weight. Sandwich panels with polygonal cores are widely used in different structural applications such as aircraft floor panels, control surfaces, civil engineering structures and many more. The main use of these panels is to reduce weight and material usage. These panels undergo various static and dynamic loading along with thermal environment. This project is a comparative study of PVC (Poly Vinyl Chloride), PU (Poly Urethane), GRF( Glass Reinforced fibre) all these sandwich materials. So there is requirement to develop the material which can be used easily for various engineering applications.
