Sema and Soma in the Poems about Death by Constantine P. Cavafy
Authors: Krasniqi Nysret
Published: January 2023

The aim of this article is to analyse Constantine P. Cavafy’s poems on death with the help of theoretical and hermeneutical literary principles and the interplay of the Greek words sema (“a grave”) and soma (“the body”). The aim is to study their forms and symbolisms as one of the fundamental motifs of Cavafy’s oeuvre. Simultaneously, the article will compare the poetic symbols with ancient philosophy on death (exemplified by Plato), as well as with the later authors’ (for instance, Stéphane Mallarmé’s) symbolistic considerations of death, which inspired Cavafy’s, modern, poetry. Through a textual analysis of his poetry on death, the poet’s influence and the sense of destruction he arouses in the reader will be explored. Furthermore, the article will focus on the thymotic power of his poetry, arguing that this author of historical heritage—that is, of the inheritance of Eros inheritance—is also an author of the inheritance of Thanatos.

Modernizam AGM-ova flanera i postmoderni medijasferni flanerizam Branka Čegeca
Authors: Franjić Luka , Trojan Ivan
Published: January 2023

U središtu je pozornosti članka prikazati odnos Matoševa modernog književnog opusa te njegov moderni medijski flanerizam nasuprot postmodernom intermedijskom književnom flaneriranju Branka Čegeca, oslanjajući se pritom na teorijska razmatranja Dubravke Oraić Tolić, Krešimira Nemeca, Igora Gajina te Gorana Galića. U članku se sažima povijest pojma flanera i flanerizma, s naglaskom na njegovu primjenu na Čegecov i Matošev opus. Budući da subjekt u Čegecovim poetskim tekstovima meandrira označiteljskim putanjama, vidjeti nam je kakva je njegova pozicija u odnosu spram subjekta u Matoševim tekstovima. Analiza potvrđuje kako se Čegec postmodernističkom aparaturom, uz dakako literarne odmake, oslanja na intermedijalne izvore i tragove kao i Matoš te mu na taj način šalje simbolični postmoderni odgovor.

Authors: Dillon-Pérez Francisco , Rojas-Londoño David , Lara-Ramos Elizabeth , Freire-Muñoz Irina
Published: January 2023

Los procesos de orientación vocacional y profesional deberían permitir al estudiante de bachillerato seleccionar una carrera universitaria orientada a su proyecto de vida. Sin embargo, son muchos los estudiantes que desertan en los primeros semestres de la universidad debido a diversos factores (económicos, emocionales, psicopedagógicos, entre otros). Entre estos se encuentra también la falta de orientación profesional y la construcción de tareas vocacionales y profesionales que consoliden esa elección de carrera. El objetivo del presente trabajo de investigación consistió en determinar la influencia del proceso de orientación profesional en la elección de carreras universitarias en estudiantes de tercero de bachillerato. El enfoque utilizado fue cuantitativo de tipo explicativo y correlacional apoyado en un proceso de análisis cualitativo de tipo hermenéutico interpretativo. La población de estudio fue seleccionada a través de un muestreo intencional y estuvo conformada por 342 estudiantes de tercero de bachillerato de diversas instituciones educativas públicas y particulares de Ecuador. Como instrumentos de investigación se utilizó una batería de prueba de aptitudes e intereses profesionales y una entrevista de base estructurada. Los resultados del estudio estadístico realizado han permitido identificar la influencia de la orientación profesional en la elección de una carrera universitaria en la población de estudio. Se concluye por consiguiente que, este proceso podría ayudar a los estudiantes de este contexto a elegir una carrera profesional alineada a su proyecto de vida y potencial aptitudinal.

Diagnosticou-se a ausência de um produto que propiciasse aos alunos o sentimento de pertencimento ao lugar e que os estimulassem como protagonistas do espaço. Em seguida, realizou-se a aplicação de metodologias de projeto de produto por meio de análise biônica, biomimética, croquis e modelagem 3D. Como premissa do estudo, o produto deveria abarcar uma visão sustentável, sendo essa incluída com o uso de um material renovável como alternativa aos convencionais, neste caso o bambu. Como resultado de inovação de novo produto, chegou-se a uma mesa em bambu com altura regulável e design lúdico. Conclui-se que o novo produto, além de incorporar requisitos sustentáveis, pode ressignificar e favorecer a infraestrutura do espaço escolar, exigindo mínima quantidade em recursos materiais para a geração de um ambiente de aprendizagem mais independente e agradável.
MITIGATION OF ADDITIONAL OVERDESIGN IN PORTLAND CEMENT CONCRETE BY OPTIMIZING THE CEMENTITIOUS MATERIALS CONTENT
Authors: Antunes Rodrigo
Published: January 2023

More cement does not necessarily make better concrete or expedite construction schedules. In contrast, concrete with lower cementitious content can reach sufficient strength on time to avoid construction delays and last longer. Standard specifications require concrete overdesign (OD) for decades, but studies assessing the actual OD magnitudes are rare. This experimental study aimed to identify the required cementitious materials content (RCC) to meet the OD based on 958 compressive strength tests (σ) representing 8200 m3 of ready-mixed concrete for threshold buildings. The actual OD in commercial concrete appears to be 7 to 21% higher than required. The cementitious materials content should be reduced between 6 and 17% so that concrete can reach the required compressive strength (f’cr) without cement overconsumption. The additional overdesign (AOD) increased significantly as the specified compressive strength (f’c) increased, indicating that concrete producers can be more cautious when the f’cr is higher. Further research is needed to expand the range of cementitious contents and applications.

Longitudinal trajectories of region-level suicide mortality in Tokyo, Japan, 2011 to 2021
Authors: Suzuki Asuka , Yamaoka Kazue , Inoue Mariko , Tango Toshiro
Published: January 2023

Background: Suicide mortality in Japan has declined over a period of more than 10 years, however, differences in longitudinal trajectories at a regional level are not well characterized. Objective was to clarify the longitudinal suicide mortality trajectories at the regional level in Tokyo from 2011 to 2021 by considering spatial smoothing, before and during the COVID-19 pandemic. Methods: This longitudinal cross-sectional analysis used fifty-four regions in Tokyo, Japan. Suicide mortality trends used data from the Cabinet Office of the Japanese government from 2011 to 2021. Regional social and environmental characteristics were used as 10 covariates. Empirical Bayes estimates for the standardized mortality ratio were obtained. A conditional autoregressive (CAR) model was applied to capture the spatial correlation for a crude and adjusted with 10 covariates using OpenBUGS. Spatial clusters were also identified by FlexScan, SaTScan, and Tango’s test. Results: Longitudinal trajectories for both males and females were similar to a decreasing trend in all Japan until 2019. In 2020, the beginning of the COVID-19 pandemic, the age-specific suicide deaths were the highest among those in their 20s. However, those were the highest among males in their 50s in 2021. The results of the CAR models adjusted for 10 covariates detected several regions as having higher suicide rates, but those regions were somewhat varied. Conclusion: During the COVID-19 pandemic, both sexes in their 20s and males in their 50s showed a tendency toward an increase in suicides. The detected regions by spatial epidemiology varied with sex.

PESCADORES ARTESANAIS NA GESTÃO PARTICIPATIVA DE RECURSOS HÍDRICOS
Authors: SANTOS Edson dos , OLIVEIRA Ticiano Rodrigo Almeida , SOUZA Susana Menezes Luz de , CUNHA Maristela CaséCosta
Published: January 2023

A apropriação dos recursos hídricos, de forma prioritária, para fins econômicos frequentemente limita os usos múltiplos e costumeiros feitos pelos pescadores artesanais, eliminando suas concepções tradicionais de domínio e uso, e impulsionando a origem ou agravamento de conflitos. Algumas bacias hidrográficas brasileiras são hidroterritórios permeados por conflitos relacionados a gestão dos recursos hídricos, contudo uma parcela desses conflitos não é discutida, mesmo nos ambientes decisórios como as instâncias do Sistema Nacional de Gerenciamento dos Recursos Hídricos (SINGREH). Esse trabalho teve como objetivo avaliar a participação dos pescadores artesanais na gestão de recursos hídricos brasileiros. Para isso foi feito uma pesquisa bibliográfica em diferentes bases de dados. Os resultados do estudo demonstraram que apesar das comunidades tradicionais possuírem assentos assegurados nas instâncias do SINGREH, observa-se que a presença dos pescadores nesses fóruns é utilizada para legitimar os interesses de outras categorias. Identificou-se que o cerceamento dos territórios pesqueiros é a principal causa dos conflitos envolvendo os pescadores artesanais e que a gestão participativa é uma estratégia exitosa em resolução de conflitos. No entanto, a gestão compartilhada necessita de mudanças para o alcance da valorização dos diferentes atores da sociedade. Também foi evidenciado a importância de outras estratégias e espaços que objetivam o compartilhamento da gestão de recursos e resolução desses conflitos

A INFLUÊNCIA DA INTERDISCIPLINARIDADE NA MUDANÇA DO CONCEITO DE DESENVOLVIMENTO
Authors: FALLER Ronaldo Josué , FERRAZ Marialda Souza Bueno
Published: January 2023

Este artigo tem como objetivo abordar e trazer uma breve reflexão de como a interdisciplinaridade influenciou, através de abordagens multidimensionais, a mudança no conceito de desenvolvimento ao longo do tempo. Essas novas abordagens incorporaram ao longo da segunda metade do século XX, sobretudo nas últimas décadas do século e início do século XXI, outros saberes para além da perspectiva econômica tradicionalmente relevante na construção do conceito de desenvolvimento baseado no crescimento. A necessidade de respostas ao fenômeno do desenvolvimento passa a absorver as contribuições das demais áreas do conhecimento, sem com isso excluira importância do econômico, a fim de responder às necessidades impostas pela realidade dos povos e pela busca de soluções mais abrangentes em um mundo de enorme heterogeneidade e complexidade.
“Let’s transform!”: A systematic literature review of science learning in COVID-19 pandemic era
Authors: Nurwidodo N. , Ibrohim I. , Sueb S. , Husamah H.
Published: January 2023

Currently, the world’s science learning is being affected by COVID-19 pandemic, which requires researchers to address it. Researchers’ attention and concern for the theme of science learning is highly expected, as evidenced by the existence of publications in reputable journals. The purpose of this systematic literature review is to review and compare investigations of research on articles published by Scopus-indexed journals (published during COVID-19 pandemic: 2020-2022). The researchers used a “science learning” phrase in the search menu of Scopus database and 1,484 articles were found by the researchers. Furthermore, 62 articles met the criteria to be analyzed. The inclusion and exclusion model used was preferred reporting items for systematic reviews and meta-analysis. Based on the results of the analysis, we found that in the last three years, there had been a decline in research on science learning. The science issues could be approached through quantitative, qualitative, mix-method, case study, and even development research. Marianne Kinnula is the author who has received the most attention in the study of science learning. According to the data, it is known that science learning and science education keywords are the most dominant keywords that used in a publication. There are 36 countries of origin for authors who publish articles, with the majority coming from Europe, though Indonesia has the most publications (Asia). Science articles are written by authors from all over the world. It was discovered that more articles were published as a result of collaboration. There are 69 institutions globally that fund science learning research and publications. We offer three perspectives on transformation science learning during a pandemic that can be used as a baseline and reference by other researchers or education policymakers. As an implication, the second and third perspectives from transformation that we have formulated are interesting for further study.

Experimental Investigation on Adsorption of Methyl orange Using eggshells as adsorbent Surface
Authors: Al Nasir Hareer A. , Mohammed Suhad  S.
Published: January 2023

The role of residues in the adsorption process for removing contaminants from their aqueous solution was highlighted in this study. The adsorption capacity of eggshells were used to remove the methyl orange dye from its aqueous solution. The highest dye adsorption was found to range between (62.30% to 62.33%). The results of using adsorption isotherms (Freundlich, Langmuir, and Temkin) have been revealed that the Freundlich model was followed and that the Langmuir model did not match, as well as the partial applicability of Temkin's model at temperatures (298,308,318) K. The process of adsorption is a physical one. Three kinetic models of the adsorption process were also used, with the results demonstrating the applicability of the pseudo-second-order model. In this study, the thermodynamic functions were estimated using the value of the enthalpy ΔH°, which was negative and equal to (-4.7685 KJ/mole), The process was discovered to be exothermic, and the entropy ΔS° value was also negative, equaling (- 11.5100 J/mole.K), indicating a decrease in the randomness of adsorption when added to the Gibbs free energy ΔG°, indicating that the reaction occurred spontaneously.

Published: January 2023

Diabetes mellitus is a set of metabolic diseases, the most prevalent of which is chronic hyperglycemia. The culprits include insulin synthesis, insulin action, or both. Osteoporosis is a progressive systemic skeletal disorder defined by decreased bone mass and micro architectural degeneration of bone tissue, resulting in increased bone fragility and fracture risk, according to the World Health Organization (WHO). The degree of Nervosa damage determines how much a diabetic patient's body has been compromised. The current study's goal is an estimation: Age, BMI, FBS, HbA1C, D3,  ALP, Ca, P, and  Osteocalcin in Iraqi T2DM Women's patients with and without Osteoporosis. Three vitamins are required for Osteocalcin biosynthesis: vitamin K for Gla formation, vitamin C for hydroxylation of Pro-9 to hydroxyproline, and vitamin D for Osteocalcin production stimulation. Vitamin D is known to function in calcium homeostasis and bone metabolism.
Osteocalcin is a hormone produced by osteoblasts and secreted into the extracellular matrix of bone and the bloodstream. It serves as a biological marker for bone formation. The work was classified into three groups. G1 (n= 40) is the control set that went to the Iraqi Ministry of Health's Endocrinology and Diabetes Center in Baghdad. G2 (n= 40) are patients with type 2 diabetes mellitus without Osteoporosis who visited the Endocrinology and Diabetes Center of the Iraqi Ministry of Health in Baghdad, and G3 (n= 40) are patients with type 2 diabetes Mellitus with Osteoporosis.

Authors: Chebabhi Ali , Barkat Said , Kessal Abdelhalim
Published: January 2023

The present paper proposes a combined voltage-oriented control and direct power control (VOC-DPC) method associated with the backstepping control technique for a three-phase four-wire grid-connected four-leg rectifier in the synchronous rotating frame without using phase locked loop (PLL) and Parks transformation under balanced and unbalanced load and grid conditions. This control method is proposed in order to remove the drawbacks of the conventional VOC based on the PLL technique .The proposed control method is able to enhance the control performance and dynamic responses of the system when considering slow dynamics and instability issues of the PLL in several cases and can decrease the computational burden due to the absence of PLL and Park transformation. In addition, the performance of the proposed VOC-DPC method is enhanced by using backstepping control (BSC) based on Lyabonov theory for both the input currents and DC-bus voltage loops. As a consequence, constant DC-bus voltage, unit power factor, sinusoidal input currents, and neutral current minimization can be accurately carried out under both DC-bus voltage and load variations. Furthermore, robustness against filter inductance variations can also be achieved. The effectiveness, superiority, and performance of the proposed control method for a four-leg rectifier based on BSC in the dq0-frame are validated by several processor-in-the-loop (PIL) co-simulation tests sing the STM32F407 discovery development board.

Objective During the lockdown of cities and home quarantine, media became the only way for people to conveniently get coronavirus disease-2019 (COVID-19)-related information. And media engagement was closely related to psychological outcomes. But fewer researchers took COVID-19-related posting behaviors into consideration. Therefore, the present study aimed at examining the differences in psychological outcomes between people who posted COVID-19-related content on social media and those who did not.Methods The present study included 917 participants (304 males, 613 females) who had answered the questionnaires of media engagement, positive affect, negative affect, depression, anxiety, stress, satisfaction with life, death anxiety, and meaning in life.Results Results of t-tests showed that the Post group had lower levels of negative affect, anxiety, stress, and death anxiety than the Not Post (Npost) group. Network comparison tests indicated that the Npost group’s network and the Post group’s network differed in global strength, two edge-weights, and node centrality indices.Conclusion The results indicated that more attention should be paid to people who did not post any COVID-19-related content, especially when they have higher levels of stress and depression to prevent comorbidities. And for people who posted content, more attention should be paid when they have a higher level of negative affect.

Objective To explore risk factors for dry mouth and examine the clinical utility of the heart rate variability (HRV) test in the prediction of dry mouth.Methods Every outpatient, who underwent tests for both unstimulated salivary flow and HRV, was retrospectively reviewed. After excluding seven subjects, the demographics and clinical factors in 70 total patients were collected. Based on objective salivary flow rates, patients were classified into normal (≥0.2 mL/min) or hyposalivation groups (<0.2 mL/min), and inter-group comparisons were performed with a two-tailed statistical significance of 0.05.Results Patients with subjective dry mouth were significantly more likely to show hyposalivation. Advanced age, female sex, and current use of psychotropic medications were identified as risk factors for dry mouth. However, dry mouth was not associated with any HRV parameters.Conclusion HRV test did not demonstrate a clinical utility in predicting dry mouth. Because subjective dry mouth is significantly associated with objective hyposalivation, a simple probing question would be useful for early recognition of dry mouth. Clinical attention is required for patients meeting criteria of older age, female, and/or using psychotropic prescriptions. Prompt management of hyposalivation may improve quality of life and clinical outcome by enhanced treatment adherence.

Objective Aerobic exercise may be associated with changes in brain activity within the default mode network (DMN) and dorsal attention network (DAN). We hypothesized that changes in functional connectivity (FC) within the DMN and DAN might be most effectively activated by moderate-intensity exercise.Methods Resting-state functional magnetic resonance imaging scans and visuospatial attention tests after resting were performed before and after each of moderate- and high-intensity aerobic exercises (10 min each) in 15 healthy male volunteers.Results The reaction time during the attention test increased significantly, and the rate of correct responses decreased from moderate-intensity exercise condition to high-intensity exercise condition. FC within the DMN under high-intensity exercise condition was higher than that under pre-exercise and moderate-intensity exercise conditions. FC within the DAN under moderate-intensity exercise condition was the highest, whereas FC between the DMN and DAN under moderate-intensity exercise condition was the lowest. Changes in cognitive domain functions were associated with changes in FC between the DMN and DAN.Conclusion Our results support the inverted-U hypothesis of maximum arousal efficacy during moderate exercise. Both cognitive domains, namely, the attention system and brain activity domains, may be better under moderate-intensity exercise than under high-intensity exercise.
