ANÁLISE DINÂMICA NÃO LINEAR DE ESTRUTURAS RETICULADAS POR MEIO DO ELEMENTO FINITO CORROTACIONAL CONSIDERANDO O CISALHAMENTO E DIFERENTES MATRIZES DE MASSA
Authors: Antonio Farani de Souza Luiz
Published: December 2023

RESUMO: Os efeitos de segunda ordem em estruturas com alto índice de esbeltez podem desempenhar um papel importante no que concerne ao comportamento mecânico de tais estruturas, visto que implicam no aumento do risco de instabilidade. Adicionalmente, a análise estática linear pode não descrever o comportamento real de uma estrutura submetida a diversas solicitações externas, especialmente no caso de situações atípicas, como sismos e rajadas fortes de vento. Nesse contexto, uma formulação corrotacional do Método dos Elementos Finitos é implementada computacionalmente com o programa livre Scilab para a análise não linear dinâmica de vigas e pórticos. Os modelos de viga de Euler-Bernoulli e de Timoshenko são utilizados para avaliar a matriz de rigidez e o vetor de força interna do sistema estrutural. O pseudocódigo do procedimento incremental e iterativo baseado nos métodos de Newton-Raphson e de Newmark é apresentado, o qual é utilizado para obter a solução aproximada da equação diferencial do movimento. Para verificar a eficácia da formulação implementada, análises dinâmicas transientes de estruturas com não linearidade geométrica encontradas na literatura são efetuadas. Além disso, são apresentadas as três primeiras frequências naturais das estruturas. Os resultados numéricos evidenciam a importância da escolha adequada da matriz de massa e da consideração do efeito de cisalhamento na rigidez do sistema estrutural, contribuindo no desenvolvimento de modelos computacionais para análise e projeto de estruturas.

Published: December 2023

The aim of our study was to evaluate differences in explosive isometric knee extension strength adaptations after a flywheel squat resistance training programs performed under low- and high-load conditions. Twenty physically active adults were randomly assigned to an individually allocated high- or low-load eight-week training intervention. Isometric knee extension RTD and RER variables were assessed pre and post eight-week intervention. Statistically significant improvements in the RTD slope variables (100 and 200 ms time intervals after the onset of torque rise; p < 0,05) were observed, regardless of the training load used. Normalized averaged vastus lateralis and rectus femoris electromyography (EMG) amplitude decreased in the intervals 80 ms before, and 75, 100 and 200 ms after the onset of activation (all p < 0,05), regardless of the training group. Our results suggest that high- and low-load resistance flywheel training interventions induce similar increases in explosive knee extension strength, accompanied with a decrease in time-analog normalized EMG signal amplitude.

Authors: Turda Sebastian
Published: December 2023

For most parents, the birth of their child is a reason for joy because the child is the center of their Universe. He is light, hope, smile, change, and future. Raising a child with a disability can have a profound impact on the family. This causes great stress for parents, especially for the mother. Prolonged stress negatively influences their quality of life, causing health problems and having a high level of fatigue, anxiety, and depression. This research aimed to investigate the level of parental stress among mothers of children with autism spectrum disorder respectively, among mothers of children with Down syndrome. The results of this study demonstrated significant differences regarding the measured variables among mothers of children with ASD and Down syndrome. Regarding coping mechanisms, mothers of children with ASD use religious coping more frequently compared to mothers of children with Down syndrome, who use the following coping mechanisms: active coping, planning, seeking instrumental support, seeking emotional support, acceptance, mental disengagement, and venting. Additionally, the level of parental stress is higher among mothers of children with ASD, and their quality of life is lower; the tendency of social isolation is at a fairly high level.
Cross-Cultural Differences in Empathy, Listening-Styles, Mindfulness and Intersubjectivity in American and Polish Counseling Discourses
Authors: Latavietz Beatrice , Fiorini Jody , Sekulowicz Malgorzata
Published: December 2023

Empathy and mindfulness, that require an attentive attitude towards the speakers, plus de-automated listening skills and collaborative discourses of American and Polish counselors-in-training, are analyzed for developmental patterns and cross-cultural comparisons. The results of the mixed methods analysis reveal that American counselors-in-raining outrank their Polish counterparts in both affective and cognitive empathy, suggesting their greater metacognitive and empathic awareness. By contrast, Polish counselors-in-training show greater focus on people and content during listening (rather than time, for example), which suggests their aural mindfulness. Developmental (pre-/post comparisons) and cross-cultural patterns identified in the (meta)discursive analysis of 124 audio-recorded counseling sessions suggest differential conceptualizations of mindfulness and empathy as expressed in professional discourse by the American and Polish counseling-students. While the American counseling discourse features mostly implicit stance, attenuated and sentiment-rich counseling moves, the Polish discourse showcases epistemic/ evidence-rich reasoning and intersubjective, camaraderie-building ‘social-lubrication.’ Cross-cultural differences reflect different conceptualizations of client needs. Implications are offered for active-listening modification (for the US counseling-students) and multi-dimensionality of empathic-awareness and expression (for the Polish students) in order to enhance mindfulness in counseling-techniques, pedagogy, and/ or therapy-sessions.
ENVIRONMENTAL SAFETY OF ATMOSPHERIC AIR IN THE ZONE OF INFLUENCE OF THERMAL POWER PLANTS WHILE USING SUNFLOWER WASTES
Authors: Oskina Maryna , Honcharenko Ihor , Ryzhchenko Olga
Published: December 2023

Air pollution is a significant and escalating global issue, posing a major threat to public health. Each year, it directly contributes to 6.5 million premature deaths, primarily due to cardiovascular and respiratory diseases resulting from exposure to air pollutants, notably fine particulate matter (PM). Beyond its well-documented health effects, recent evidence from epidemiological studies and controlled animal research underscore its detrimental impact on cognitive function and brain health. It's worth noting that residing in heavily polluted areas is linked to increased cognitive impairment and a heightened risk of neurodegenerative conditions. This association is particularly strong with pollutants stemming from energy and transportation, such as PM and nitrogen oxides (NOx). The intricate nature of PM pollutants, particularly ultrafine particles (UFP) with a diameter of less than 100 nm, enables them to infiltrate the human body, bypassing various protective mechanisms. Given this context, investigations into the influence of solid-fuel power plants, recognized by the European Environment Agency as major contributors to atmospheric air pollution, are of utmost importance. Existing regulatory and methodological frameworks do not adequately address contemporary realities and requirements, especially concerning the assessment and control of the environmental impact of thermal power plants using agricultural waste as fuel. This study aims to provide scientific and theoretical support for additional aspects related to the emissions of thermal power plants and their effects on both humans and the environment. This research holds particular significance when evaluating the placement of such facilities near populated areas and when making informed decisions regarding energy production technologies from renewable sources.

Published: December 2023

Renal angiomyolipoma is a benign mesenchymal neoplasm of kidney and composed of varied proportions of adipose tissue, smooth muscle cells- spindled or epithelioid and dysmorphic thickened or hyalinised blood vessels. Epithelioid angiomyolipoma is one of the rare variants of angiomyolipoma with high degree of complications, recurrence and metastasis. Whereas classic angiomyolipoma does not show metastasis and recurrence. Giant epithelioid angiomyolipoma means tumor size measuring greater than10 cm, very few cases have been reported in literature. Epithelioid angiomyolipoma of size greater than 20 cm is extremely rare.
Here we report a rare case of giant epithelioid renal angiomyolipoma of size greater than 20 cm in a 21-year-old female, presented with complaints of right flank pain and hematuria.
The patient underwent nephrectomy with probability of malignancy given in ultrasonography and specimen was sent for histopathological examination. Gross examination revealed enlarged kidney of size 22×18×10 cm and cut section shows grey white to yellow lesion measuring 21×17×10 cm almost occupying entire kidney. Microscopic examination revealed interlacing fascicles of spindle cells, lobules of adipocytes and thickened blood vessels. Foci of pleomorphic epithelioid cells with illdefined cell borders, pleomorphic vesicular nucleus and prominent nucleoli are noted.

Authors: Fadillah M. Ikhsan , Nasution Syafrizal , Ramadani Sumi
Published: December 2023

Background: ESRD is a burdensome disease with high prevalence, mortality, and treatment costs. Indoxyl sulfate is one of the most studied solutes accumulating in plasma when the kidneys fail. Clinical studies have shown that indoxyl sulfate can predict the prognosis of CKD and CVD in CKD patients. Serum levels of IS are associated with all-cause mortality and cardiovascular mortality in CKD patients. The general objective of this study was to determine the relationship between indoxyl sulfate levels and the functional ability of CKD patients undergoing regular hemodialysis using the Karnofsky scale measuring instrument at the Haji Adam Malik Central General Hospital Medan.
Methods: This research is an observational analytic study with a cross-sectional design. Data collection involved recording indoxyl sulfate levels in kidney failure patients undergoing hemodialysis at Haji Adam Malik Hospital.
Results: Of all 56 study samples, the mean age was 49.35 years, with a standard deviation of 12.3 years. Most patients were male, from the Batak ethnicity, with hypertension as the etiology. The mean indoxyl sulfate level was 47.32 µg/mL with a 29.19 µg/mL standard deviation. Most patients presented with functional ability calculated by Karnofsky score in category A. The analysis results with the Spearman test showed a moderate negative correlation between indoxyl sulfate levels and the functional ability of patients.

‘Religion is the Opium of the People’: An FDA Analysis on the Construction of Religion by Young Greek Adults
Authors: Ganotis Athanasios , Louka Penelope , Pilafas Georgios
Published: December 2023

This study examines the discourses constructed around religion in Greek society, focusing on the transition from conservative religious beliefs prevailing in micro societies to a more accepting discourse at the macro societal level. The research employs a qualitative approach, specifically utilizing Foucauldian Discourse Analysis (FDA) on 7 interviews of young Greek adults, to explore the evolving landscape in Greece and the power dynamics of religion influenced by education, social interaction, and relevant discourses, resulting in a diminished influence of religion over time. The findings reveal the presence of tolerance towards religious diversity, challenging the traditional conservative discourse, which is characterized by strict adherence to Orthodox religious practices and resistance to religious pluralism, while also highlighting the declining power of religion. The study demonstrates how individuals aligning with the acceptive discourse value their own religious beliefs while fostering co-existence with individuals of different religious groups, without being heavily influenced by the church. Notably, younger generations, shaped by an era emphasizing social interaction, exhibit a stronger alignment with this discourse. By illuminating the shaping of identities and orienting actions within these discourses, this research contributes to the understanding of religion in Greek society. It underscores the significance of religion as a subject warranting ongoing scholarly attention and highlights the need for future research to explore the complexities of religious beliefs and discourses across the country using varied methodological approaches.

Published: December 2023

Background: The use of myocardial cytoprotectors (meldonium) in patients with exertional angina is a scientific-practical dilemma. Material and methods: An open randomized clinical trial was conducted involving 160 patients with chronic heart faliure (117 men and 43 women) aged 37 to 81 years. Of them, 142 patients had angina pectoris of stable effort from different functional classes, and 21 – unstable angina pectoris. Study groups were comparable according to the frequency of indication of background drugs and meldonium. Results: The number of patients with normal diastolic function in both groups, but with a net superiority to meldonium combination administration, has considerably increased: 41 patients (91.11%) in group II vs 33 (58.93%) in the group treated with basic treatment after 9 months of medication; 43 patients (95.56%) group II vs 36 (64.29%) in group I at 12 months of medication. During this period, no patients with pseudonormal type of diastolic dysfunction were registered, these passing into a ”more” favorable category – delayed relaxation. Conclusions: The data obtained confirmed the benefit of using cardiocitoprotection in inducing the reverse-remodelling of the myocardium of left ventricle regardless of the initial ventricular geometric pattern, but the administration of mildronate combination demonstrated a significantly superior efficiency to the basic treatment in hypertrophy of left ventricle regression, an event notable towards the end of the research period.

Authors: Sumarga Natalia , Belii Adrian
Published: December 2023

Background: In this study the organization of long-term anticoagulant treatment has been evaluated to estimate whether clinical practice is in accordance with current recommendations for optimal use and effective control of oral anticoagulant (OAC) treatment. Material and methods: Mixed (quantitative and qualitative), transversal, descriptive, selective study. Samples: quantitative study – 394 adult patients, eligible for anticoagulant treatment; qualitative study – 39 family doctors. Results: The rate of use of OAC treatment is 68%. The period from the diagnosis of the disease to the initiation of OAC treatment lasted one month or more in 59.1% of patients. 60.6% of patients do not have sufficient knowledge regarding the treatment of OAC. The high price is the most important barrier to direct oral anticoagulant administration (91.1%). Patients’ satisfaction with OAC treatment control is low, mainly for vitamin K antagonists (59.8%). 75.5% of respondents claim that OAC treatment control and management is poor. 40.3% do not perform safe therapeutic International Normalized Ratio control, and 54.7% are not in the optimal therapeutic range. Conclusions: The main barriers to adherence to OAC treatment: the burden of regular monitoring of blood parameters, perceived concern about complications, limited access to laboratory tests and specialist doctors, insufficient information about anticoagulation, and deficiencies in communication with medical staff. There is limited conviction, and uncertainty persists in the initiation and monitoring of OAC treatment by family doctors.

Authors: Alfiqi Rahmat , Sembiring Jaka Persada
Published: December 2023

The term "tunanetra" is used to refer to someone who experiences total blindness or visual impairment. Such visual limitations result in visually impaired individuals facing difficulties in accessing information quickly and performing daily activities like walking, driving, and more. Walking is one of the crucial activities for visually impaired individuals because it is one way to explore the world and engage in daily activities. Based on this issue, an assistive device for the visually impaired was designed using embedded system technology. In 2022, Serly Juliana Taneo, Jonshon Tarigan, Frederika Rambu Ngana, and Andreas Ch. Louk developed a mobility aid device for individuals with visual impairments using ultrasonic sensors for distance detection and Arduino as the microcontroller. However, the device primarily focused on mobility, and there is a need to add new features, such as emergency information using SMS technology that can send messages with the press of a button. The research results indicate that the ultrasonic sensor successfully triggers vibrations within a range of 1-100 cm, and the button can send emergency notifications via SMS when pressed. Therefore, it can be concluded that all connected components can function as intended. By combining SMS technology and ultrasonic sensors, this assistive device is expected to enhance the safety and independence of individuals with visual impairments as they navigate their surroundings.

Published: December 2023

The digital representation of flowers, characterized by their vivid chromatic attributes, establishes them as viable candidates for deployment as input imagery within the object recognition paradigm. Within the context of object recognition, the imperative of a proficient image segmentation process is underscored, serving to effectively discern the object from its background and, consequently, optimizing the efficacy of the object recognition process. This research unfolds through a methodologically structured tripartite framework, encompassing the initial stage involving input imagery, the subsequent intermediate phase dedicated to image segmentation, and a conclusive stage centered on the quantitative evaluation of methodological outcomes. The second stage, focusing on image segmentation, employs the Otsu thresholding and multilevel thresholding methods. The subsequent third stage involves a thorough assessment of segmentation outcomes through the application of quantitative metrics, including Peak signal-to-oise ratio (PSNR) and Root Mean Square Error (RMSE). Empirical investigations, incorporating a diverse array of floral input images, reveal a conspicuous inclination towards a specific segmentation methodology. Specifically, the Otsu Thresholding method emerges as the more judicious choice relative to multilevel Thresholding, demonstrating superior performance with a diminished RMSE value and an augmented PSNR value, substantiated by an average RMSE value. This research is propelled by the overarching objective of discerning the most optimal method for the segmentation of flower images, particularly in the face of diverse input images. Its significant contribution lies in providing nuanced insights into the discerning selection of segmentation methodologies, attuned to the variability inherent in diverse forms of input imagery, thereby culminating in optimized outcomes within the domain of flower image recognition. Where did these results come from? please show it in the sub-discussion.

Authors: Kwak Su-Joung , Choi Eun-Mi
Published: December 2023

This study sought to determine whether the perception and behavior of nail coloring was influenced by the personal color interest of women in their 20s. The results of comparing the interest in color and perception and behavior of nail coloring according to nail coloring characteristics and the results of awareness and behavior level of nail coloring showed a statistically significant difference. This signifies that personal color makes effect on nail coloring. Considering that there was no significant difference in characteristics of nail coloring by type according to the visual measurement results of the visual measurement objects, it does not appear to affect the nail coloring characteristics of each type according to the visual measurement results. The comparison between the visual measurement result of the measurement object and the cube (hand) measurement results showed a difference from the visual measurement result but was not statistically significant. Based on these results, it seems that the concordance between the cloth measurement result and the cube(hand) measurement result was low. This signifies that accurate diagnosis of personal color would be necessary. As a result of examining the perception and behavioral level of nail coloring before and after the personal color diagnosis of the subject, there was a statistically significant increase in perception and behavior level of the measurement group. It was identified that they are related to personal color perception, positive image impact, and satisfaction with nail color. In other words, it was identified that personal color diagnosis is very important in nail coloring and makes effect on the difference in awareness and behavioral level. By investigating whether recognition of nail coloring according to interest in personal color affects behavior through this study, it will be useful data for continuous and systematic customer management method if it is used for personal color nail coloring that suits personal characteristics.
