Published: October 2024

BACKGROUND

The working environment of submarine crews is also very special. They are in a closed, high-temperature, high-noise, high-vibration and narrow working and living space for a long time, and they suffer from physical discomfort caused by seasickness, which will affect the mental health of officers and soldiers. American psychologists have achieved positive results in psychological resilience training for officers and soldiers from the perspective of positive psychology. At present, there are few reports on the correlation between psychological resilience in the field of domestic research on submarine crew psychology, and it is necessary to conduct further research.

AIM

To explore the impact of active psychological regulation intervention on officers and soldiers operating in confined spaces at sea.

METHODS

A total of 121 soldiers working in a confined space of a large ship were randomly divided into an experimental group and a control group. The 50 soldiers in the experimental group were given a training course intervention, while the 71 soldiers in the control group did not receive any intervention measures. The Pittsburgh Sleep Quality Index, Psychological Resilience Scale, military Psychological Stress Self-Assessment Questionnaire, and General Self-Efficacy Scale scores were compared before and 6 months after the intervention.

RESULTS

Under the positive psychological control intervention, except for sleep efficiency (P = 0.05), the difference between the remaining dimensions of the Pittsburgh Sleep Quality Index scores and the total scores of the experimental group compared with the control group was statistically significant (P < 0.05); the assessment of the psychological condition showed that, in addition to the Psychological Stress Self-assessment Questionnaire for Military Personnel scores (P = 0.05), the scores of the Mental Toughness Scale (Dispositional Resilience Scale Resilience II) in the experimental group, General Self-Efficacy Scale scores were statistically significant (P < 0.05) compared to pre-intervention.

CONCLUSION

Positive psychological intervention and control can improve the sleep state and psychological state of officers and soldiers working in confined space at sea.

Streptomyces species are promising resources of bioactive compounds that play a vital role in medicinal biotechnology. Streptomyces sp. SA31 was isolated from the rhizospheric soil of Cymbopogon citratus (DC) Stapf. The strain was identified as Streptomyces samsunensis based on genome-based taxonomic analysis. The draft genome of strain SA31 contained 11,850,342 bp with a high percentage of G+C at 71.0% and carried 9,350 predicted protein-encoding sequences (CDSs). Furthermore, the secondary metabolite biosynthesis gene clusters in the genome of strain SA31 were predicted by antiSMASH. In silico analysis showed 71 predicted biosynthetic gene clusters (BGCs) responsible for antimicrobial secondary metabolite synthesis. Most gene clusters were involved in the biosynthesis of polyketide synthase. The genome of strain SA31 harbored seven types of polyketide biosynthesis gene clusters that might be associated with antimicrobial activity. Additionally, the genome of strain SA31 contained unexplored secondary metabolite biosynthesis gene clusters. In vitro antimicrobial assay showed that an ethyl acetate extract from the culture broth of strain SA31 could inhibit the growth of Staphylococcus aureus ATCC 25923, Kocuria rhizophila ATCC 9341, Bacillus subtilis ATCC 6633, Candida albicans ATCC 10231, and Aspergillus flavus IMI 242684, implying that the genome of strain SA31 contained potential BGCs for the production of antimicrobial secondary metabolites and led to the isolation of geldanamycin and 17-O-demethylgeldanamycin.  Therefore, it can be proved that the rhizosphere-associated soil of C. citratus (DC) Stapf. is a rich habitat for actinomycetes that are capable of producing promising biologically active compounds.

The commercial particleboards used nowadays are manufactured with synthetic adhesives containing formaldehyde which is considered harmful to health and has a negative impact on the environment. A binderless particleboard fabricated from agricultural waste materials can solve these issues. This research explored the feasibility of using rice straw and banana pseudostem to produce binderless particleboard. The optimal preparation conditions for production were carried out using the ratios of rice straw to banana pseudostem at 100:0, 75:25, 50:50, 25:75 and 0:100, the pressing temperatures of 140°C, 160°C, and 180°C, and the compression times of 10 and 30 min. The physical and mechanical properties of the particleboard including density, moisture content, thickness swelling, modulus of rupture and modulus of elasticity were investigated. Morphological analysis was studied by scanning electron microscopy. It was found that it was possible to produce binderless particleboard from rice straw and banana pseudostem using a hot press method. The results showed that a higher content of banana pseudostem led to good mechanical properties and adhesion with lower thickness swelling. Cross-section of the binderless particleboards revealed that banana pseudostem acted as a binder.  Fourier transform infrared spectroscopy (FTIR) also confirmed the occurrence of self-bonding in these binderless particleboards. The optimum preparation conditions were achieved with the ratio of rice straw to banana pseudostem of 0:100, and a pressing temperature of 180°C for 30 min. The modulus of rupture (MOR) and modulus of elasticity (MOE) were approximately 12 MPa and 1800 MPa, respectively. This binderless particleboard is a potential candidate for use in green buildings.

This paper showcases the kaupapa (philosophy) and practices of a Māta Waka (pan-tribal), community-based Kaupapa Māori service provider in the nation-state currently known as New Zealand. Te Hou Ora Whānau Services aims to provide services that support and empower tamariki (children) and rangatahi (youth) to fulfil their potential within the context of their whānau (extended families), their cultural heritage, and their communities. The purpose of this study was to explore the philosophy and values that underpin the everyday practices and experiences of eleven kaimahi (practitioners) who work for the provider. Analyses of the data identified five overarching pou, or foundational supports that underlie kaimahi ways of being, knowing, relating, and doing, together with seven ‘takepū,’ or preferred ways of engaging with others. Te Hou Ora Whānau Services’ holistic philosophy and practice offers an important window into Māta Waka community-based Kaupapa Māori services that are responsive to tamariki, rangatahi and whānau Māori from diverse backgrounds and lived experiential realities. While some of the elements are specific to the New Zealand context, the pou and takepū offer guidance relevant to programs globally that seek to successfully and creatively respond to the priorities, aspirations, and moemoeā/dreams of Indigenous children, young people, their families, and communities.

Published: October 2024

The challenge of developing further usable Web operations has motivated the appearance of several ways, styles, and tools to address Web usability issues. Although there are numerous proffers for supporting the development of usable Web operations, numerous inventors aren't apprehensive of them and innumerable associations don't duly apply them. This paper reports on a systematic review of usability evaluation styles in Web development. The idea of the review is to probe what usability evaluation styles have been employed by experimenters to estimate Web vestiges and how they were employed. An aggregate of 51 exploration papers has been reviewed from an original set of 410 papers. The results show that 45 of the papers reviewed reported the use of evaluation styles specifically drafted for the Web and that the most employed system is stoner testing. In addition, the results of the review have linked several exploration gaps. Specifically, 80 of the evaluations are still performed at the perpetration phase of Web operations development and 47 of the papers didn't present any confirmation of the usability evaluation system(s) employed. Keywords: Usability Evaluation Methods, Web development, Systematic Review.

Published: October 2024

This article investigates the importance of social media in customer service and relationships, causing engagement with the brand. For this, this research's corpus delimited the actions on social media of the five largest banks in Brazil in terms of customer volume. The data were collected and analyzed in two moments: first, through a structured questionnaire to test the use and importance of social media in the service and relationship of banks; second, through the collection of interaction and conversation data on the social media of each bank studied. The quantitative and descriptive research uses correlation and engagement analysis based on social media metrics. The results indicate the banks' different strategies to provoke engagement and relationship with their consumer audiences in each media, but the data reveal low engagement. However, consumers pointed out social media's relevance in seeking services and relationships with their banks, citing the convenience, speed, and accessibility it provides. The study concludes that consumers value banks' social media, especially looking for customer service and relationships. In contrast, interaction and conversation data showed that banks have a routine of working in this category, combining others with their products' promotion and sponsorships and events. However, it became clear that the engagement that the banks' social media actions generate is minimal, in proportion to the volume of their followers.

The seizure of agrochemicals is a persistent issue in Brazil, mainly in states bordering other South American countries, which experience the highest levels of agrochemical confiscations. We evaluated biochemical parameters, including oxidative stress, hepatotoxicity, and cytotoxicity of the herbicide quinclorac (QCR) using a sample obtained from a seizure. The herbicide was characterized using Gas Chromatography-Mass Spectrometry and thermal analysis. Additionally, hemolytic activity, along with MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide), neutral red (NR), and lactate dehydrogenase (LDH) assays in Zebrafish Liver (ZF-L) cells, were performed to assess QCR cytotoxicity. The results showed IC50 values of 19.83 µg/mL for erythrocytes and 1.78 µg/mL, 5.13 µg/mL, and 0.95 µg/mL for MTT, NR, and LDH assays, respectively. A median IC50 of 3.46 µg/mL was used for cholinesterase (COL) and aspartate aminotransferase (AST) dosages, as well as oxidative stress assays, which revealed an increase in reactive oxygen species (ROS) production, along with a decrease in total sulfhydryl (SH) content and the activities of superoxide dismutase (SOD) and catalase (CAT). Furthermore, QCR exposure resulted in elevated AST levels, indicative of liver damage, and a biphasic response in COL activity, with a significant reduction at higher concentrations. Our research indicates that QCR induces hepatotoxicity and cytotoxicity via oxidative stress in the ZF-L cell line under in vitro conditions.

Authors: Wang Shikai , Zhang Haodong , Zhou Shiji , Sun Jun , Shen Qi
Published: October 2024

This paper presents a new method for chip floorplanning optimization using deep learning (DRL) combined with graph neural networks (GNNs). The plan addresses the challenges of traditional floor plans by applying AI to space design and intelligent space decisions. Three-head network architecture, including a policy network, cost network, and reconstruction head, is introduced to improve feature extraction and overall performance. GNNs are employed for state representation and feature extraction, enabling the capture of intricate topological information from chip netlists. A carefully designed reward function incorporating wire length minimization, area utilization, and timing constraint satisfaction guides the DRL agent toward high-quality floorplan solutions. An exploration bonus based on reconstruction error addresses the sparse reward problem. Extensive testing of the ISPD 2005 benchmarks demonstrated the effectiveness of the proposed approach, consistently operating on a state-of-the-art basis. Significant improvements include an average 31.4% reduction in half-perimeter wire length (HPWL) and a 34.2% reduction in breach time compared to the best baseline performance. The process scalability and robustness are evaluated, showing performance in various circuits and different perturbations. This research advances AI-driven electronic device design and paves the way for better chip design processes.
Drawing Parallels Between Language Change Processes: Grammaticalization, Constructionalization and Phraseologization
Authors: Sánchez-López Elena
Published: October 2024

Over the last decades, the acknowledgment of the dynamic character of language has led to the focus on language evolution and change. Among the different streams of linguistics, Historical linguistics (morphosyntax), Construction Grammar and Phraseology have paid attention to these processes, studying grammaticalization, constructionalization and phraseologization, respectively. The three frameworks we are dealing with were quite different in origin, but through the adoption of cognitive, usage-based, pragmatic approaches they are tending to converge. In this paper we will outline the respective frameworks, their conception of language unit and the process of change, including its mechanisms and stages. In each section, we will include some applications in Catalan language. As we consider them to be complementary, since they account for different items of language, at the end we will suggest an integration of the three of them.

USO DE MARCADORES BIOLÓGICOS NOS REGISTROS POR ELETROENCEFALOGRAMA (EEG) PARA RESPOSTAS A ESTÍMULOS MUSICAIS: IMPLICAÇÕES PARA A SAÚDE MENTAL E NEUROPLASTICIDADE
Authors: Capita Zaika
Published: October 2024

Este artigo teve como objetivo revisar, de forma integrativa, o impacto dos estímulos musicais monitorados por eletroencefalograma (EEG) sobre a neuroplasticidade e a saúde mental. Foram analisados 20 estudos que utilizaram diferentes gêneros musicais e avaliaram seus efeitos sobre os padrões de ondas cerebrais, bem como sobre aspectos emocionais e cognitivos de pacientes saudáveis e clínicos. A música clássica mostrou-se capaz de induzir predominantemente ondas alfa (8-12 Hz), associadas ao relaxamento e à redução da ansiedade, enquanto a música mais rítmica, como a eletrônica, induziu ondas beta (13-30 Hz), correlacionadas à atenção e ao processamento cognitivo. Pacientes com transtornos do espectro autista (TEA) e doenças neurodegenerativas, como Parkinson, apresentaram melhora na conectividade cerebral e na cognição social após a exposição à música interativa e rítmica. A revisão demonstrou que a música pode ser uma intervenção terapêutica eficaz, promovendo o bem-estar emocional, modulação cognitiva e reorganização das redes neurais. Conclui-se que a música possui potencial terapêutico valioso para a saúde mental e reabilitação neurológica, embora sejam necessários mais estudos para padronizar as intervenções musicais e suas aplicações clínicas.
O PAPEL DO HIDROGÊNIO MOLECULAR NA MODULAÇÃO DE PROCESSOS OXIDATIVOS E INFLAMATÓRIOS NO ORGANISMO HUMANO: UMA REVISÃO DE SEUS EFEITOS TERAPÊUTICOS
Authors: Capita Zaika
Published: October 2024

O hidrogênio molecular (H₂) tem sido amplamente estudado por suas propriedades antioxidantes e anti-inflamatórias. Esta revisão integrativa teve como objetivo explorar os mecanismos de ação do H₂, com foco na sua aplicação em doenças crônicas e degenerativas, incluindo doenças cardiovasculares, neurodegenerativas e inflamatórias. Através da análise de ensaios clínicos e pré-clínicos publicados entre 2010 e 2024, constatou-se que o H₂ exerce um efeito protetor contra o estresse oxidativo ao neutralizar seletivamente espécies reativas de oxigênio (ROS), como o radical hidroxila (•OH) e o peroxinitrito (ONOO−). Além disso, o H₂ regula a inflamação, reduzindo os níveis de citocinas pró-inflamatórias, como TNF-α e IL-6, ao mesmo tempo que aumenta a produção de citocinas anti-inflamatórias, como IL-10. Os estudos analisados também mostraram que o H₂ melhora a função endotelial em pacientes com doenças cardiovasculares e possui efeitos neuroprotetores significativos em modelos de isquemia-reperfusão cerebral. No entanto, as evidências ainda são limitadas por ensaios clínicos com amostras pequenas e pela falta de padronização em relação à dosagem e via de administração do H₂. Conclui-se que o hidrogênio molecular é uma terapia promissora, segura e com potencial para ser aplicada em uma variedade de condições clínicas, mas são necessários mais estudos robustos para validar seus benefícios terapêuticos em larga escala.

Published: October 2024

Os sistemas de produção de bovinos de corte em confinamento, vêm crescendo no Brasil impulsionados por diversas razões, entre elas a maior necessidade de intensificação da produção e a possibilidade de oferta de animais gordos no período de maior escassez das pastagens. Trata-se de uma atividade complexa que demanda o controle de diversas variáveis, as quais devem ser cuidadosamente analisadas durante o ciclo de produção. Desta forma, objetivou-se compreender o perfil técnico da produção de bovinos de corte em 15 confinamento distribuídos em 09 municípios da região Oeste do estado de Goiás. Foi aplicado questionários com 30 perguntas aos gestores e colaboradores dos confinamentos no ano de 2023, tendo como referência o ciclo produtivo de 2022. Os dados foram analisados com o auxílio do Statistical Package for Social Science, (IBM Corporation, Armonk, USA) versão 26,0. O nível de significância adotado foi de 5% (p < 0,05). A grande maioria dos confinamentos (80%) usufruíram de algum tipo de assistência técnica durante seu processo produtivo. Pouco mais da metade (53,3%) produziram seus próprios bovinos a serem confinados e 46,7% utilizaram algum tipo de software específico para gestão de confinamentos. O atendimento a programas de bonificação pelo tipo de animal produzido esteve presente em 60% dos confinamentos avaliados. Foi constatado que 60% dos confinamentos avaliados apresentaram algum tipo de produção agrícola própria para uso na engorda dos animais. Os problemas sanitários mais frequentes relatados nos animais foram ocorrências laminite (33,3%) e pneumonia (33,3%).

A produção de fogos de artifício em Santo Antônio de Jesus se confunde com a própria tradição dos festejos juninos, tendo o trabalho artesanal e domiciliar como principais características e alternativa de sobrevivência para a parcela empobrecida de sua população. Em 11 de dezembro de 1998 uma fábrica de fogos de artifício, localizada na periferia da cidade, explodiu matando 64 pessoas e deixando outras cinco gravemente feridas, dentre as quais, em sua maioria mulheres e crianças, negras e pobres. A tragédia, expôs ao mundo um incômodo cenário de negligência, clandestinidade, ilegalidade e precarização das relações de trabalho. Diante da sugestiva omissão e violação de direitos, por parte do Estado, o caso foi levado à Corte Interamericana de Direitos Humanos, que acolheu a denúncia apresentada. Nesse sentido, o presente estudo investigou a atuação deste Tribunal, em suas funções contenciosa; de supervisão; consultiva e na elaboração de medidas em defesa dos direitos humanos. A base de dados para a elaboração do artigo, foi uma análise documental. Assim, concluiu a Corte Interamericana de Direitos Humanos, que ao conceder autorização e não fiscalizar o funcionamento e as condições de trabalho no estabelecimento, o Estado brasileiro se tornou responsável pelas mortes e feridos na explosão, pelas condições laborais ao qual estavam submetidos os trabalhadores, assim como é seu dever a reparação dos danos causados aos sobreviventes e familiares.

The cryopreservation effective use is intrinsically linked with reproductive success for the reproductive biotechnologies application, facilitating genetic material storage. Alternative ways of collecting semen in dogs open up new horizons for use by veterinarians in clinical routine. This work aims to evaluate the cryocapacity of semen samples collected by urethral catheterization after pharmacological stimulation using dexmedetomidine. The pharmacological collection and digital manipulation techniques was compared using 5 dogs without statistically significant results (p>0.05) for fresh semen samples for motility (86 ± 5.48 manual vs. 79.7 ± 12.45 catheter), vigor (3 ± 0.1 manual vs. 10.46 catheter), plasma membrane integrity (83.5 ± 8.15 manual vs 77.2 ± 15.72 catheter) or cryopreserved for motility (53 ± 13.5 manual vs 43 ± 17.17 catheter), vigor (1.8 ± 0.57 manual vs 1.7 ± 0.44 catheter), acrosomal integrity (53.7 ± 16.17 manual vs 50 ± 22.01 catheter), plasma membrane integrity (52.8 ± 18.37 manual vs 40.4 ± 21.18 catheter). There was a statistical difference (p<0.05) when comparing seminal volume (3.24 ± 1.36 manual vs 0.35 ± 0.11 catheter) and sperm concentration (115.6 ± 79 manual vs 259.6 ± 81.75 catheter). Based on the findings, it is possible to state that the semen collected by urethral catheterization after pharmacological stimulation showed favorable results for cryopreservation.

Este artigo tem como objeto a análise histórica do desenvolvimento da educação profissional no Brasil, com objetivo analisar as políticas públicas e reformas educacionais que influenciaram a formação profissional, destacando a tensão entre as demandas do mercado e a necessidade de uma formação integral e, avaliando os desafios e avanços na melhoria e promoção de uma educação mais inclusiva e equitativa. Foi realizada uma pesquisa documental, em leis, decretos e bibliografia sobre a temática, com a indagação social da importância da educação profissional para o país. Os resultados mostraram que, apesar dos avanços na promoção da igualdade de oportunidades para os jovens da educação superior e da educação profissional, científica e tecnológica em nível médio e técnico das instituições federais brasileiras, persistem desafios significativos, como a resistência à mudança nas práticas pedagógicas e a influência das demandas do mercado de trabalho. A superação efetiva da dualidade educacional depende de uma reformulação dos currículos e de uma abordagem pedagógica que valorize a articulação entre teoria e prática, promovendo o desenvolvimento integral dos estudantes.
Predictive value of tooth and sinuses radiological characteristics in managing odontogenic sinusitis of endodontic origin

Background: One of the most common causes of bacterial odontogenic sinusitis (ODS) is endodontic disease with periapical lesions (PAL). Referrals between otolaryngologists and dental specialists are indispensable for proper diagnosis and treatment. If the disease does not resolve after medical and root-canal treatment (RCT), tooth extraction, endoscopic sinus surgery (ESS) or both are the ways of management.The aim was to clarify the predictive value of disease’s radiological characteristics for the further surgical intervention. Methodology: 68 symptomatic patients evaluated by an otolaryngologist and dental specialist were included to this prospective observational cohort study. Patients who failed medical treatment of sinusitis (intranasal steroids, saline rinses and antibiotics) and RCT were treated either with ESS, tooth extraction or both at the same time.Results: 87% of patients required surgical intervention. 12% improved after tooth extraction alone, 47% after ESS and 31% required both procedures. The degree of maxillary sinus’ (MS) opacification was not correlated with the need of invasive procedures implementation, as opposed to ostiomeatal complex’ patency (p<0.001). Cortical bone destruction towards the MS and multiple tooth roots involvement suggested ODS resolution only after combined surgical approach (p=0.041).Conclusions: Radiological characteristics of causative tooth and patency of ostiomeatal unit correlate with the evolution of ODS and need for either ESS and/or tooth extraction. Patients with multiple roots affected, shorter distance to the MS floor and PAL’s with visible bone destruction may require tooth extraction and ESS to resolve ODS completely.Clinical implications: Radiological data may help in earlier diagnosis and treatment of ODS with PALs for both otolaryngologists and dental specialists.

Introduction: Bone conduction hearing implants (BCHI) are a widely used rehabilitation solution for patients with conductive hearing loss (CHL), mixed hearing loss (MHL), or single-sided deafness (SSD).Aim: This expert review presents candidacy criteria considerations when choosing between active transcutaneous bone-conduction hearing devices (Osia System) and passive percutaneous bone-conduction hearing devices (Baha Connect System) to help streamline the decision-making process in those contexts where economics have a major impact on professionals’ and patients’ choice.Methods: Eight experts participated in two online surveys and two virtual meetings to discuss real-world clinical experience to highlight treatment approaches and factors considered when counseling the patients and selecting an optimal BCHI solution. Key considerations for decision-making were recorded following consensus from all experts.Conclusions: Aspects in decision making include the requirement to use local versus general anesthesia for the implantation procedure, bone thickness, considerations for future magnetic resonance imaging (MRI) procedures, and patient preference. Increased risk of skin infections, requirements for cleaning and managing the implant site, particularly for those with limited dexterity, as well as esthetic concerns could make the Baha Connect System unsuitable for some patients. In these cases, the Osia System may provide clear advantages, particularly in patients for whom good hearing performance is a priority, and this would need to be discussed individually with the patient in a multidisciplinary setting. Conversely, for patients requiring minimally invasive surgery, who have contraindications for general anesthesia or require frequent head MRI scans in the future, the Baha Connect System may be more suitable.
