Objetivo: Relatar a experiência de estudantes de enfermagem com a utilização de dispositivos lúdicos na assistência de enfermagem em uma emergência pediátrica. Relato de experiência: A experiência é descrita a partir de três perspectivas: primeira ação, reflexão sobre a ação, nova ação. Na primeira ação os estudantes sentiram que durante a assistência ficou prejudicado o estabelecimento de um vínculo entre estudante, criança e pais. No momento de reflexão, ao relacionar a vivência com os conteúdos ministrados em sala de aula, principalmente no que tange ao estabelecimento de vínculos, os estudantes idealizaram uma estratégia de abordagem por meio de dispositivos lúdicos. Na nova ação, com a utilização dos dispositivos, as crianças demostraram estar mais alegres e dispostas a contribuir e os pais se propuseram a discutir, abertamente, sobre o quadro clínico dos filhos. Considerações Finais: Ressalta-se a relevância da experiência no processo de formação, pois a utilização de dispositivos lúdicos precisa ser transversal em todas as disciplinas que assistem pessoas, e em especial, nas que assistem crianças, pois potencializam o estabelecimento de vínculos e tornam a assistência de enfermagem mais humanizada.
A Study of the Korean Counselors’ Perception on Gerontological Counseling
Authors:   Korean Journal of Research in Gerontology, Kim Haelee , Lee Young Soon
Published: May 2024

Although the number of older adults in need of psychological help is increasing due to the increase in their population in Korea, there is a shortage of counselors qualified to provide the appropriate services for them. In order to activate gerontological counseling, there is a great need to explore the counselors’ perception of counseling for the older adults. Accordingly, 75 counselors with at least two years of counseling experience after graduating from a master’s program were asked through an open-ended questionnaire about their perceptions of the characteristics, counseling process, and counseling outcomes for the older clients. The counselors responded to the questionnaire online and the response data were analyzed using Consensual Qualitative Research Analysis. There were a total of 647 statements collected, they were classified into 61 subcategories, and the subcategories were integrated into 4 themes and 17 categories. The first theme was named ‘the characteristics of the older clients,’ and the counselors generally perceived them negatively such as stubborn people. The second theme was named ‘their need for counseling,’ and the counselors thought that the older clients would consider the counselor as a sympathizer to their problem but not a counseling expert. The third theme was named ‘the gerontological counseling process’, and the counselors recognized that the personality traits of older adults such as resistance to change and the age difference with the clients would make the counseling process difficult. The fourth theme was named ‘the gerontological counseling outcome,’ and the counselors recognized that the mental health problems of the older clients would be resolved to some extent even if the counseling outcomes for them were not great. The findings of this study confirmed that general counselors have negative stereotypes about older clients or aging. The authors raised the need for training to correct this negative perception of counselors and strengthen counseling competencies for the older adults in a super-aged society where gerontological counseling becomes more and more important in the last part of this paper.

Published: May 2024

Influenza A viruses spread out worldwide causing several global concerns. Discovering neuraminidase inhibitors to prevent the influenza A virus is thus of great interests. In this work, a machine learning model was trained and tested to evaluate the ligand-binding affinity to neuraminidase. The model was then used to predict the possibility of compounds from the CHEMBL database, which is manually curated database of bioactive molecules with drug-like properties. The physical insights into the binding process of ligands to neuraminidase were clarified via molecular docking and molecular dynamics simulations. Experimental studies on enzymatic and antiviral activity as well as cytotoxicity have validated our computational results and suggested that 2 compounds were potential inhibitors of neuraminidase of the influenza A virus.

Published: May 2024

Electrochemical CO2 reduction will be a key player in net-zero technologies, yet its industrial implementation is limited. Improvements by fine-tuning the microenvironments, electrolyte environments around the catalytic sites, have been scarce due to the interplay between electrode kinetics and transport. Here, we couple atomistic insights with continuum transport via ab-initio multiscale modeling, explicitly including electrolyte effects at all scales. The model was validated on Ag planar electrodes in several liquid electrolytes and the current dependence with voltage aligns with experimental observations. We show that a balance between CO2 diffusion and cation accumulation needs be achieved to obtain optimal rates. In ionomers, this limitation can be overcome since organic cations-based microenvironments are present at a fixed concentration, but water management becomes critical. Our approach paves the way towards rational microenvironment design in electrochemical CO2 conversion.

Heterocyclic spirocyclic compounds as structurally unique compounds are present in many natural or bioactive compounds. Not surprisingly, developing novel methodologies that enable stereocontrol access toward spirocyclic compounds represents an important goal in modern synthetic chemistry. The main interest is oriented toward developing methods for accessing spirooxindoles. On the other hand, the development of their oxygen-containing cousins is still overlooked. Here, we report a simple organocatalytic spiroannulation method, which provides access to spirocyclic benzofuran-2-ones. The utility of the protocol was underscored by gram-scale reaction and follow-up transformations.
On the mechanism of electron-beam-induced structural degradation in ZIF-8 and its electron dose tolerance

Published: May 2024

Zeolitic-imidazolate-frameworks (ZIFs) are crystalline microporous materials that have already shown promising application potential in areas such as gas adsorption and catalysis. Further research advances include studies on integrating ZIFs into nanodevice concepts. In detail for the application e.g. of electron-beam-assisted structural modifications or patterning, there is a need to understand potential structural degradation processes caused by such electron beams. Advanced transmission electron microscopy (TEM) has demonstrated its ability to study structures at the nanoscale. Here, we systematically investigated electron-beam-induced loss in crystallinity in ZIF-8 under various experimental conditions, using as measure the attenuation of the intensity and the relative displacement of electron diffraction Bragg spots with increasing cumulative electron dose. The intensity and the fading of the {110} Bragg spots indicate the overall stability of the ZIF-8 unit-cell structure, while the {431} Bragg spots are a measure of the stability of ZIF-8’s micropore structure. We considered a relative loss of Bragg spot intensity of 37% as the threshold for the critical total electron dose, which was found to be different for different Bragg planes, with 35.6 ± 8.4 e-Å-2 for {110} and 11.4 ± 3.0 e-Å-2 for {431}. However, the critical dose per breakage of Zn-N bonds in a ZnN4 tetrahedra per different Bragg plane was found to be ~ 3 e-Å-2. This indicates continuous, simultaneous breakage of Zn-N bonds throughout the crystal, confirming radiolysis as the dominant damage mechanism. In addition, we investigated the effects of TEM experiment parameters, including acceleration voltage, electron dose rate, cryogenic sample temperature, in-situ sample drying, as well as change in conductivity of the sample substrate (e.g., graphene). Our results unravel the degradation mechanisms in ZIF-8 and provide threshold parameters for maximizing resolution in electron-beam-assisted experiments and processes.

Published: May 2024

Research into novel materials with tailored properties is essential to improve CO2 adsorption and activation, a fundamental preliminary phase in catalytic CO2 conversion processes. Here, we have employed density functional theory-based calculations to investigate CO2 activation over the pristine and Cu-decorated carbon-based two-dimensional material ψ-graphene and its hydrogenated forms, i.e. ψ-graphone (half hydrogenated) and ψ-graphane (fully hydrogenated). ψ-graphene is a metallic allotrope of graphene containing 5-6-7 membered carbon rings. Our study found exothermic binding of CO2 at all three materials (for both pristine and Cu-decorated materials), indicating spontaneous physisorption. The presence of a single Cu atom plays a significant role in increasing the activity of ψ-graphene towards CO2 activation. By decorating ψ-graphene with Cu atoms, the adsorption energy at ψ-graphene increases about three times, whereas no significant variation is observed on ψ-graphone and ψ-graphane sheets. We used Bader charge analysis and electronic density of states plots to further quantify the nature of the interaction between CO2 and these materials.

On the grounds of artificial intelligence sensors, the research focuses on achieving precise detection of intelligent posture to minimize the risk of injuries resulting from incorrect body positioning and to mitigate the negative impact on both performance and physical well-being. Utilizing an attitude analysis and recognition system that relies on the nertial measurement unit enables not only the measurement of human body motion information but also the acquisition of data pertaining to motion characteristics and body movement states through the examination of posture data. A proposition is presented for intelligent posture training that is centered on accuracy and real-time feedback. Furthermore, it is elucidated that the accuracy of posture recognition through machine learning is significantly influenced by variations in user BMI. This paper will introduce the most recent advancements in posture recognition techniques, providing an overview of the various methodologies and algorithms that have emerged in recent years. Additionally, it delves into enhanced approaches such as stacked hourglass networks, multi-stage pose estimation networks, convolutional pose machines, and high-resolution nets. The study thoroughly dissects and consolidates the general procedures and datasets involved in posture recognition, comparing several enhanced CNN methodologies alongside three principal recognition techniques. Moreover, it delves into the utilization of advanced neural networks in posture recognition, including but not limited to transfer learning, ensemble learning, graph neural networks, and explainable deep neural networks. Researchers have observed that CNN has made significant strides in the realm of posture recognition and has garnered favor, yet emphasize the necessity for further exploration into areas such as feature extraction and information fusion.

O biomonitoramento é o processo de avaliação ambiental com o uso de organismos vivos para compreender desequilíbrios e reações biológicas causados por elementos antropogênicos. A espécie Echinodorus grandiflorus (Alismataceae), uma macrófita aquática de grande distribuição geográfica na flora do Brasil, tem tem sido utilizada como monitora da qualidade de ambientes fluviais. O presente estudo avaliou a capacidade de bioacumulação de metais pesados nos órgãos vegetativos dessa espécie e sua interação com as características de uso e ocupação do solo ao longo de um rio urbano em Santa Catarina. Foram coletadas amostras de raízes, caules e folhas em seis pontos amostrais do corpo principal do rio para avaliar a influência antropogênica nas concentrações de alumínio, zinco, níquel, chumbo e cobre em diferentes órgãos da espécie. Observou-se maior concentração de alumínio, zinco, cobre, níquel e chumbo, respectivamente. As folhas apresentaram a maior concentração de metais, seguidas pelas raízes e caules. Foi identificado um padrão crescente nas concentrações dos metais em direção à foz do rio, porém apenas as diferenças nas concentrações de alumínio e níquel, entre os pontos de coleta, foram estatisticamente significativas. A espécie E. grandiflorus mostrou alta capacidade de bioacumulação de metais pesados, sendo possível considerá-la um biomarcador eficaz da qualidade ambiental fluvial em áreas poluídas.

O Estado do Maranhão registra altos índices de desmatamento e focos de queimadas, especialmente nas regiões sul e sudeste, onde os biomas Cerrado e Amazônico estão presentes. Diante desse contexto, destaca-se o município de Amarante, localizado na região sul do estado, que abriga o segundo maior rebanho de gado e desempenha um papel significativo como polo agropecuário. Além disso, o município está integrado à Fronteira Econômica do MATOPIBA. O presente estudo tem como objetivo analisar o uso e cobertura da terra e sua relação com o fogo nas Terras Indígenas do Município de Amarante, Maranhão, Brasil. Utilizando técnicas de sensoriamento remoto e análise de dados geoespaciais, busca-se investigar os padrões de desmatamento, fragmentação florestal e ocorrência de incêndios nessas terras indígenas. Por meio de uma abordagem temporal, analisando o período de 1985 a 2020 com intervalos de 5 anos entre cada recorte, foram obtidos resultados que revelam uma correlação direta entre o avanço das atividades agropecuárias, a frequência de queimadas, o desmatamento e a exploração ilegal de madeira na região. O estudo também destaca o aumento da violência e dos conflitos territoriais decorrentes da expansão dessas atividades econômicas, afetando diretamente as populações indígenas e evidenciando a tensão territorial relacionada ao uso e cobertura da terra. Diante dessas constatações, ressalta-se a urgente necessidade de implementar estratégias de conservação e manejo sustentável do uso da terra nas áreas indígenas, visando à proteção da biodiversidade e dos modos de vida tradicionais.

Published: May 2024

O rio Paranaíta, importante tributário da bacia Teles Pires, tem sido impactado por processos antrópicos devido principalmente à agropecuária e hidroenergia. Analisar as dinâmicas geoambientais das bacias hidrográficas amazônicas é fundamental para construção de estratégias de gestão ambiental e territorial, e, estas perpassam inicialmente pela identificação das características dos sistemas ambientais, a partir de diagnósticos que considerem a integração dos diferentes elementos da paisagem, como dinâmica geoambiental e hidrológica. O estudo objetivou analisar a dinâmica geoambiental e qualidade da água na bacia do baixo Paranaíta. A caracterização geoambiental foi realizada partir do geoprocessamento de dados geoespaciais disponibilizados em bases de dados oficiais e a avaliação da qualidade da água com amostragens in loco e análises laboratoriais. Os dados geoespaciais foram geoprocessados e gerados produtos cartográficos para caracterização espacial. Os dados de qualidade da água foram tabulados e realizada análise de estatística descritiva. Os resultados demonstram a fragilidade ambiental do baixo Paranaíta, em razão do predomínio de áreas com declividades superiores a 3%, associada a ocorrência de Argissolos que naturalmente apresentam maior suscetibilidade à erosão e a redução da cobertura florestal entre os anos analisados, com decréscimo de quase 22%. Com exceção do fósforo total, demais parâmetros estão em conformidade com a legislação de enquadramento dos corpos hídricos. No entanto, destaca-se que as transformações da paisagem na região, especialmente com o avanço da fronteira agrícola, indicam a necessidade de ações de planejamento e controle para garantir o ordenamento territorial na bacia e garantir os usos múltiplos da água em quantidade e qualidade adequadas.

Published: May 2024

The parathyroid glands are essential endocrine glands as they produce hormones that maintain calcium within the normal level in blood through secretion of parathormone. The removal of parathyroid glands leads to fatal levels of hypocalcemia. The number of parathyroid glands is species specific. The current investigation was performed on 20 healthy freshly slaughtered adult male goats. Fifteen specimens were immediately fixed in 10% buffered neutral formalin, then processed for histological and immunohistochemical examination. Other 5 specimens were handled for transmission electron microscope. The present work was conducted to study the morphological and histological characteristics of parathyroid glands of goat. Parathyroid glands comprised of two pairs, each pair formed from external and internal glands. External parathyroid gland was rounded or oval in shape. Its location was varied in the same animal where it may be located cranial to thyroid gland or beside the submandibular salivary gland. Internal parathyroid gland was embedded inside thyroid tissue. It appeared as pale rounded area at the end of cranial part of the right and left thyroid lobe. The histological findings demonstrated that, each parathyroid gland is surrounded by a thin capsule of dense irregular connective tissue. The glandular parenchyma is divided by short thick septa into ill distinct compartments. Each compartment had numerous numbers of chief cells. The active chief cells were polygonal in shape with oval nuclei. Immuno-histochemical findings revealed that they are positively reacted against chromogranin antibody. Electron microscope revealed that the cytoplasm have abundant mitochondria, rough endoplasmic reticulum, evenly distributed golgi apparatus and numerous secretory granules. On the contrary, the inactive chief cells have more vacuolated cytoplasm which contains less cell organelles.

Published: May 2024

Tilapia nilotica (Oreochomis niloticus) is the major fish species consumed in Egypt, particularly due to its high nutritive value, palatability and relatively low price compared with other kinds of fishes or red meat. In Egypt, tilapia fish is caught directly from river Nile or cultured in a specified aquaculture. Organochlorine pesticides (OCPs) have been extensively used in Egypt and many African countries in the past century for the control of the agricultural pests. A major character of OCPs is their persistent bio-accumulation in the environment, especially in the food chain, where they can get reach to humans. There is few reports had investigated the current scenario of OCPs contamination in fish in Egypt, particularly in Upper Egypt cities such as Sohag. Additionally, fish is consumed cooked in Egypt not raw like many Asian countries. Therefore, this study aimed at monitoring the residue levels of different OCPs in tilapia fish caught from Upper Egypt (Sohag) and compared with either that from northern part of Egypt (Damietta) or with fish cultured in a control location (Abbasa). Additionally, the effect of different cooking methods (boiling, grilling and pan-frying) on the residue levels of OCPs was investigated. The tested OCPs included pp-DDT and its metabolites pp-DDD and pp-DDE; hexachlorohexanes (HCHs) including α HCH and γ HCH; heptachlor and heptachlor epoxide; aldrin and endrin; chlordane, methoxychlor and hexachloride benzene and were detected using electron capture gas chromatography equipped with Ni63 – electron capture detector. The recorded results revealed that tilapia collected from Damietta had the highest incidence of OCPs’ contamination (75%), over than that collected from Sohag (60%) compared to control value (35%). All examined samples had OCPs residues within the maximum permissible limits (MPLs) set by world health organization. Pan-frying had the highest reduction effect on the OCPs’ residues followed by grilling and boiling. The public health significance of the examined OCPs was also discussed.

Przedmiotem analizy jest występujący po pandemii wzrost zainteresowania rodziców edukacją domową. Wyjaśniam zatem różnicę między tą alternatywną edukacją a uczeniem się w domu w wyniku lockdownu czy edukacji hybrydowej. Na przykładzie Polski i Czech wskazuję na uwarunkowania renesansu właściwej edukacji domowej w obu krajach i jej aktualnych funkcji w kontekście autoodpowiedzialności za jej jakość, która staje się warunkiem sine qua non wyjątkowego zaangażowania i poświęcenia się przez rodziców własnemu dziecku.

Saat ini, pemanfaatan teknologi pelacakan posisi telah merambah ke berbagai aspek, utamanya dengan memanfaatkan Global Positioning System (GPS). Namun, terdapat keterbatasan signifikan dalam ketepatan akurasi GPS saat digunakan dalam lingkungan dalam ruangan. Dalam mengatasi tantangan ini, konsep Indoor Positioning System (IPS) telah diperkenalkan dan dikembangkan. IPS memungkinkan pelacakan posisi di dalam bangunan dan menawarkan bukan hanya peningkatan akurasi, tetapi juga keamanan, keselamatan, serta efisiensi yang lebih baik. Penelitian yang dijelaskan dalam konteks ini bertujuan untuk merumuskan solusi untuk pelacakan dan pengenalan lokasi dalam ruangan, dengan fokus pada lantai 7 gedung sipil. Pendekatan yang digunakan melibatkan penerapan infrastruktur titik akses yang telah ditempatkan di setiap ruangan. Dataset yang digunakan untuk mendukung analisis terdiri dari 80 titik lokasi yang ada dalam ruangan tersebut, yang secara rinci terbagi menjadi 40 titik untuk ruang LIG2, 40 titik untuk ruang LPY4, dan area koridor yang menghubungkannya. Dalam upaya untuk mencapai tujuan ini, penelitian ini mengadopsi metode Support Vector Machine (SVM). Melalui penggunaan teknik ini, model SVM diinstruksikan dengan memanfaatkan data Received Signal Strength Indicator (RSSI) dari mikrokontroler. Melalui serangkaian uji coba dan evaluasi, metode SVM yang diterapkan dalam penelitian ini telah membuahkan hasil yang menjanjikan. Tingkat akurasi mencapai 79%, mengindikasikan bahwa sistem yang diusulkan mampu dengan tepat memprediksi lokasi berdasarkan data yang terkumpul.

Background: Radiations plays an important role in various diagnostic and therapeutic procedures within health facilities, but its use poses inherent risks to both healthcare professionals and patients. Understanding the knowledge, attitude, and safety practices of physicians in relation to radiation safety is paramount for ensuring the well-being of all stakeholders involved. Physicians, as key decision-makers in medical procedures involving radiation, need to be well-informed about the associated risks and safety measures. Objective: To determine the physician knowledge, attitude and safety practice towards radiation safety. Study Design: Cross-sectional study. Settings: Pakistan Institute of Medical Sciences, Islamabad Pakistan. Duration: March 2020 to February 2021. Methods: All the physician relevant to exposure to ionizing radiation, such as radiology, nuclear medicine, interventional cardiology, and oncology, having minimum one year or more experience in radiological field of either age and gender were included.  Data collection was carried out through a structured questionnaire, specifically designed to evaluate participants' understanding of radiation safety principles, their attitudes towards adherence to safety protocols, and their day-to-day practices in radiological procedures. The collected data was analyzed using appropriate statistical methods SPSS version 26. Results: Majority of participants experience medical radiation exposure less than once per week (42.1%), with a significant portion having exposure more than three times per week (40.8%). 90.8% of participants have never undergone a radiation protection course, despite 73.7% expressing willingness to participate in such a course if provided by their institution. 52.7% strongly disagreed that radiation significantly affects childbearing, while 39.5% believe they are safe within 1 meter of radiation exposure. On a positive note, 86.8% of participants correctly identified the ALARA principle for radiation protection. Regarding the implementation of safety protocols, only 28.9% were more likely to wear a lead apron, and 22.4% never wore it. Conclusion: Health care professionals lacks adequate knowledge, training and attitude regarding radiation safety protocols. Lack of adequate knowledge and training leads to poor utilization of radiation safety equipment and it is a source of health hazard for both medical professionals and the patients.

Published: May 2024

La baja participación de la mujer en cargos directivos marca una brecha de género importante en el mercado laboral. Realidad que sublima el mérito de aquellas mujeres que han logrado alcanzar posiciones jerárquicas relevantes. Este estudio analiza las prácticas de liderazgo de mujeres que ocupan cargos directivos en Chile (Región de Coquimbo). La investigación aplicó una encuesta a setenta mujeres que dirigen empresas, basada en el Inventario de Prácticas de Liderazgo de Kouzes y Posner (autoevaluación). Los resultados mostraron que las directivas, en el ejercicio de su cargo,aplican un estilo orientado en las personas, usando las prácticas de alentar y habilitar a los demás para que actúen. Se concluye que aun cuando las competencias de liderazgo coinciden, mayormente, con un modelo de liderazgo transformacional, no son excluyentes con el de tipo transaccional. Se denota, así, una preocupación especial por el fomento del trabajo colaborativo y el reconocimiento laboral.

Published: May 2024

Los discursos sobre la seguridad y el orden se han sostenido históricamente en Argentina bajo dos modelos en disputa: el del orden público y el de la seguridad ciudadana. En este artículo indagamos el modo en que ambos modelos se configuran bajo nuevas formas en el imaginario policial durante la pandemia por Covid 19. El fin es analizar las perspectivas policiales en torno a la ley, la transgresión y la seguridad vigentes en nuestra sociedad. Para ello empleamos un abordaje cualitativo, basado en la realización de entrevistas semiestructuradas a oficiales de la Policía Federal y Provincial Argentina y de la Policía de la Ciudad de Buenos Aires, durante los meses de noviembre y diciembre de 2020 y marzo de 2021.

Teaching competencies for psychomotor skill development for manual handling techniques in the cervical regions is necessary for safe practice in physiotherapy. However, grasping anatomy and palpation can be challenging for students, and practice in the lab can lead to discomfort for students. To facilitate teaching and learning of this complex skill, we worked in partnership with a virtual reality (VR) industry partner who developed a customized VR application focusing on transverse ligament stress testing for manual therapy skills for Master of Physical Therapy (MPT) students. In this scholarship of teaching and learning (SoTL) project, eight MPT students participated in the evaluation of an innovative VR learning experience for manual therapy in the cervical spine. Students’ learning experiences with the custom virtual reality learning application were assessed using an observational study design with semi-structured interviews. Interview questions aligned with constructs that are recommended to assess learners’ attitudes toward VR environments. Student participants appreciated the usefulness of the application for studying and practicing the transverse ligament stress test and provided recommendations for enhancing the learning experience.
Modern ideas about the development of atherosclerosis

Published: May 2024

Currently, in the leading countries of the world there is a question of a significant increase in diseases associated with circulatory system disorders, but this issue should be considered together with another pathology – atherosclerosis. Analysis of modern scientific literature has shown that at the moment there is no single theory of the origin of atherosclerosis, because this disease can be caused by various factors, both endo- and exogenous. Currently, most scientists and doctors agree that atherosclerosis is a multifactorial disease, in the development of which there are complex, often long-term violations of immunologic, molecular-genetic, biochemical reactions. Many significant structural units are involved in the process of atherogenesis: the vascular wall, local disturbance of blood flow, and blood forming elements. Opinions on the etiology of atherosclerosis vary. However, most authors tend to consider dyslipidemia as the leading mechanism of atherosclerosis development; at the same time, we should not forget other possible causes of its formation.
