Authors: Romli Ikhsan , Prameswari R Shanti , Kamalia Antika Zahrotul
Published: June 2021

Sentiment analysis is a data processing to recognize topics that people talk about and their sentiments toward the topics, one of which in this study is about large-scale social restrictions (PSBB). This study aims to classify negative and positive sentiments by applying the K-Nearest Neighbor algorithm to see the accuracy value of 3 types of distance calculation which are cosine similarity, euclidean, and manhattan distance for Indonesian language tweets about large-scale social restrictions (PSBB) from social media twitter. With the results obtained, the K-Nearest Neighbor accuracy by the Cosine Similarity distance 82% at k = 3, K-Nearest Neighbor by the Euclidean Distance with an accuracy of 81% at k = 11 and K-Nearest Neighbor by Manhattan Distance with an accuracy 80% at k = 5, 7, 9, 11, and 13. So, in this study the K-Nearest Neighbor algorithm with the Cosine Similarity Distance calculation gets the highest point.

Published: June 2021

Ability to do problem solving will be greatly influenced by how the flow of thinking in decomposing a problem until it finds the root of the problem so that it can determine the best solution. There is currently a growing recognition around the world that all fields require a prerequisite ability, namely to think logically, in a structured manner, and use computational tools to rapidly model and visualize data. This ability is known as Computational Thinking (CT). In this study, the author applied the computational thinking key concept in a case study to train structured thinking in problem solving. Computational thinking key concept includes Decomposition, Pattern recognition, Abstraction, and lastly use algorithms when they design simple steps to solve problems. Based on our case study that has been model, the result shows us that Computational Thinking can be used to train structured thinking in problem solving in everyday life
A Fast Dynamic Assignment Algorithm for Solving Resource Allocation Problems
Authors: Amalia Ivanda Zevi , Saikhu Ahmad , Soelaiman Rully
Published: June 2021

The assignment problem is one of the fundamental problems in the field of combinatorial optimization. The Hungarian algorithm can be developed to solve various assignment problems according to each criterion. The assignment problem that is solved in this paper is a dynamic assignment to find the maximum weight on the resource allocation problems. The dynamic characteristic lies in the weight change that can occur after the optimal solution is obtained. The Hungarian algorithm can be used directly, but the initialization process must be done from the beginning every time a change occurs. The solution becomes ineffective because it takes up a lot of time and memory. This paper proposed a fast dynamic assignment algorithm based on the Hungarian algorithm. The proposed algorithm is able to obtain an optimal solution without performing the initialization process from the beginning. Based on the test results, the proposed algorithm has an average time of 0.146 s and an average memory of 4.62 M. While the Hungarian algorithm has an average time of 2.806 s and an average memory of 4.65 M. The fast dynamic assignment algorithm is influenced linearly by the number of change operations and quadratically by the number of vertices.

La literatura como fuente histórica. «Trafalgar» y el inicio de los «Episodios Nacionales»
Authors: González-Martín Francisco-Javier
Published: June 2021

La literatura de Benito Pérez Galdós como fuente histórica ofrece nuevos horizontes de comprensión, ampliación y profundización. Trafalgar (1873) nos da a conocer entornos como Cádiz, biografías como las de Gabriel, «Medio Hombre», Villeneuve, Gutiérrez de Cisniega, basadas en caracteres y emociones, no solo en hechos históricos. El relato como comunicación une épica y lírica y nos lleva a un nuevo método de investigación. Como expusiera Jacques Le Goff, existe una historia externa y otra interna, una historia psicológica, un motor que activa los sucesos individuales y colectivos que conforman la historiología de la que hablase Ortega o el método histórico antropológico según Caro Baroja y Morales Moya. Trafalgar es el ejemplo de hecho trascendental, mito y símbolo de una derrota, que abre el relato y memoria galdosiana de la historia contemporánea. Conceptos como heroísmo, patria, honor, decadencia en ese paso del Antiguo al Nuevo Régimen lo hacen esencial, desde esta doble perspectiva, Historia y Literatura, escasamente valorada todavía.
Las desventuras del puerto de Gijón de 1742 a 1817. Resistir a los hombres y al océano
Authors: García-Hurtado Manuel-Reyes
Published: June 2021

El puerto de Gijón, desde la década de los años cuarenta del siglo xviii, se embarca en un largo y complejo proceso que persigue su reparación, mejora y limpieza. Nos centramos en los 75 años que consideramos cruciales para evidenciar el papel que las distintas jurisdicciones y corporaciones adoptan en este proyecto, explicar las dificultades que unas y otras plantean y los cambios que se experimentan en el modelo de gestión de las obras. Este análisis contribuye a aportar una hipótesis que justifica la debilidad de las infraestructuras portuarias españolas que va más allá de la dificultad que conllevan los trabajos de ingeniería hidráulica o el coste de los mismos, y que radica, en un primer momento, en el hecho de que sean las localidades quienes gestionan las tareas de reconstrucción, en la lucha por el control de los arbitrios que debían financiar las obras y, ya en el siglo xix, en la aparición de instituciones que cuestionan abiertamente las prácticas anteriores, lo que provoca un enfrentamiento en el que el principal perjudicado será siempre el puerto, aunque saldrá reforzado de este combate final.
El vasquismo espiritual de Eladio Esparza
Authors: Mikelarena-Peña Fernando
Published: June 2021

En este artículo se analiza el vasquismo de Eladio Esparza en sus colaboraciones en la prensa: en Diario de Navarra entre 1910 y 1923 y entre 1929 y 1952, en El Pensamiento Navarro en 1911, en La Voz de Navarra entre 1923 y 1927, y en Euzkadi entre 1925 y 1929. Su figura es importante por su condición de vascoparlante nativo, por su evolución ideológica ―ya que, tras dirigir el periódico nacionalista La Voz de Navarra y colaborar con Euzkadi, fue el principal formulador del navarrismo foralcatólico desde las páginas de Diario de Navarra del que fue subdirector desde 1930― y por sus tesis a partir de 1929 en pro de un vasquismo espiritual y en contra del vasquismo político, también presentes en su novela La Dama del Lebrel Blanco.

Published: June 2021

The equivalence theorem is the most important theorem of experimental design. For single response, the D-optimal equivalence theorem of the continuous design and equal allocation design already exist. However, the equivalence theorem of D-optimal equal allocation design for multiresponse mixture experiments has not been investigated. In this paper, we study this problem and find that the maximize of the variance function of the equivalence theorem equal to the number of response. D-optimal designs for multiresponse are illustrated by two examples.

Published: June 2021

PURPOSE: Muscle strength, power, speed, postural stability, and anaerobic power are important physical fitness factors required to perform well in a taekwondo competition. This study aimed to investigate the effects of 8 weeks of core balance and plyometric training on physical fitness in young taekwondo athletes.METHODS: Nine young taekwondo athletes participated in this program. Body composition and relative fitness (muscle power, core strength, agility, postural stability, anaerobic power, and isokinetic muscle function) were measured before and after training. Data were analyzed using IBM SPSS Statistics version 23.0 (IBM Corp., Armonk, NY, USA). A paired t-test (pre vs. post) was used for the analysis.RESULTS:The core strength measured by the sit-up count changed significantly after training (p<.05). In case of postural stability, the right absolute reach distance in the Y-balance test improved significantly after training (p<.05). In case of anaerobic power, the mean power (p<.01) and the peak power (p<.01) increased significantly after training.CONCLUSIONS:We demonstrated that 8 weeks of core balance and plyometric training enhanced core strength, balance, and anaerobic power in young taekwondo athletes. Our results suggest that core balance and plyometric training are effective in improving muscle strength, core strength, balance, and anaerobic power.

Published: June 2021

PURPOSE:This study aimed to examine the effects of resistance and balance training on physical function and postural control in individuals with Down syndrome (DS).METHODS:Ten adults with DS constituted the experimental group (EX) and attended an 8-week resistance and balance training program. The results were compared with those of the control group (CON), which consisted of 10 patients who did not undergo any physical training. Body composition, postural stability, and physical fitness were measured before and after the training program. Resistance and balance training were performed for 60 minutes, three times a week for 8 weeks.RESULTS: Body weight, body mass index, body fat percentage, and waist circumference decreased significantly in the EX group after completing the 8-week resistance and balance training program. The center of pressure and the difference between standing foot pressure on the left and right were significantly improved in the EX group. Physical fitness including sit-to-stand repetitions and 10 m shuttle duration significantly improved in the EX and CON groups.CONCLUSIONS:These results suggest that resistance and balance training to improve musculoskeletal problems is an effective strategy to prevent injury, fatigue, and falls during exercise and to improve general health in individuals with DS.

Published: June 2021

PURPOSE: This study aimed to investigate the effect of turmeric intake alone or in combination with resistance training on liver enzymes in adult men who regularly consumed alcohol at least twice a week.METHODS: Twelve men (age: 36.0±5.26 years, weight: 99.9±17.9 kg, and height: 184.0±6.5 cm) were randomly assigned to the turmeric intake (2-3 g/day) alone (TI, n=6) group or the TI plus resistance training (60 minutes of RT 3 times a week) (TI+RT, n=6) group for 8 weeks. Blood was collected before and after 8 weeks of treatment. The analyzed variables included glutamic oxaloacetic transaminase (GOT), glutamic pyruvic transaminase (GPT), γ-glutamyl transferase (γ-GTP), and GOT/GPT ratio.RESULTS:There was no significant interaction effect in all variables, but the main effect was found in all variables only in TI+RT group. The Cohen’s d effect size on the main effects of the TI+RT group on GOT (d=0.548), GPT (d=0.835), γ-GTP (d=0.623), and GOT/GPT ratio (d=0.800) ranged from 0.548-0.835, respectively. However, body composition such as percent body fat (%, p>.05) and muscle mass (kg, p>.05) did not show the main effect on time points as well as the interaction effect (p>.05).CONCLUSIONS:Although the 8-week TI treatment did not show any statistically significant change, TI treatment showed a tendency to decrease in GOT, GPT, and γ-GTP, and the GOT/GPT ratio tends to increase. Therefore, there was a synergic effect of the TI plus RT treatment or the sum of the two treatments for 8 weeks.

Published: June 2021

PURPOSE: This study aimed to understand the barriers to exercise and facilitators of exercise for up to 4 weeks following breast cancer surgery.METHODS: A descriptive qualitative research method was used in this study. Twelve patients were recruited through purposive sampling immediately after breast cancer surgery.RESULTS: Physical aspects (pain at the surgery site, reduction in the range of motion, and decrease in fitness), environmental aspects (difficulty in movement due to drain, lack of information on exercise), and psychological aspects (concerns about side effects, fear of pain, and fear of injury during exercise) were identified as barriers to exercise. Expectation of positive effects (recovery from surgery, prevention of lymphedema, usefulness for future radiation therapy, prevention of cancer recurrence, and health management) of exercise and social support (hospital education, support from medical staff, and exercise information received via mass media) were identified as facilitators of exercise.CONCLUSIONS: We recognized different barriers to exercise and facilitators of exercise among patients who recently underwent breast cancer surgery. Future exercise intervention studies should consider minimizing such barriers and maximizing the facilitators identified in our study.
Laminar Shear Stress Protects Against Premature Endothelial Senescence by SIRT1-Dependent Mechanisms
Authors: Kim Ji-Seok , Sayoc Jacqueline , Baek Kyung-Wan , Park Joon-Young
Published: June 2021

PURPOSE:Accumulation of senescent endothelial cells (ECs) and development of vascular aging have been implicated in the etiology of vascular dysfunction and disease. Aerobic exercise has been recognized as the single most effective non-pharmacological anti-aging intervention via increased laminar shear stress (LSS). This study aimed to determine the protective effects of LSS against premature senescence and the underlying mechanism.METHODS: Carotid artery partial ligation surgery was performed on the left carotid arteries (LCAs) of C57BL/6J male mice to determine the effect of disturbed flow on the development of endothelial senescence. Senescence-associated β-galactosidase (SA-β-gal) staining was performed to measure cellular senescence. Expression levels of protein markers for cell senescence including p21, p16, and p53 were measured by western blotting.RESULTS: En face SA-β-gal staining was identified only in the partially ligated LCAs of voluntary wheel-running mice, suggesting a direct relevance of LSS on the prevention of vascular senescence. In the in vitro H2O2-induced premature senescence model, preconditioning of high-flow LSS (20 dyne/cm2, 36 hours) induced significant reduction in the percentage of SA-β-gal positive ECs. Expression of the molecular markers of cellular senescence such as p21, p16, and p53 was significantly decreased by LSS pretreatment. However, the protective effects of LSS against premature senescence were completely abolished by SIRT1 inhibition.CONCLUSIONS: The results suggest that high-flow LSS has protective effects against oxidative stress-induced premature endothelial senescence through a SIRT1-dependent mechanism.

Authors: Lee Yuri , Woo Jinhee , Jun Hyung-pil
Published: June 2021

PURPOSE: This study aimed to investigate the effect of pre-exercise heat pack treatment on muscle activity and markers of muscle damage after exercise-induced damage.METHODS: Ten healthy male university students were tested for 3 weeks. They were exposed to three conditions (non-warm-up exercise, warm-up exercise, and heat pack treatment) before exercise. The experiment was conducted at 1-week intervals for every participant. The warm-up exercise was performed by combining a modified active warm-up with a cycle ergometer and an isokinetic dynamometer. The main exercise, which modified the exercise-induced muscle damage protocol, was conducted by flexing and extending the knee joint using an isokinetic dynamometer. The heat pack treatment before the exercise involved moist heat application for 20 min.RESULTS: The changes in blood muscle fatigue markers and blood muscle damage markers were not significantly different between the groups (α>.05). However, significant differences were observed in the time immediately after exercise, 10-min recovery, 30-min recovery, and 60-min recovery (p<.05). A statistically significant difference was observed in the change in pain in the heat pack treatment group (p<.05).CONCLUSIONS: Heat pack treatment for 20 min before exercise did not minimize the muscle damage markers and fatigue markers following exercise-induced damage, but reduced immediate muscle soreness. Use of heat pack treatment was associated with a change in muscle activity and improvement in certain aspects of muscle soreness.

Published: June 2021

PURPOSE:This study aimed to examine the effects of non-face-to-face learning on health-related physical fitness and balance in adolescents according to the coronavirus disease 2019 (COVID-19).METHODS:Twenty-nine middle-school students (14 girls and 15 boys) were enrolled. We measured the students’ health-related physical fitness (body composition, muscle strength, muscle endurance, flexibility, and cardiac endurance) and balance (static and dynamic) before and after 12 weeks of non-face-to-face learning without any exercise intervention. Cardiac endurance was measured using the Harvard step test.RESULTS: Body fat, muscle strength (hip flexion, hip extension, knee flexion, knee extension), and Y-balance test exhibited significant differences before and after non-face-to-face learning (p<.05). Body fat, muscle strength (hip flexion, hip extension), and Y-Balance test exhibited significant differences in the female group (p<.05). Hip extension muscle strength exhibited a significant difference in the male group (p<.05). Analysis of covariance showed that muscle strength (hip extension and knee extension) and Harvard step of the female group were significantly decreased compared to the male group (p<.05).CONCLUSIONS: Non-face-to-face classes according to COVID-19 had a negative effect on health-related physical fitness and balance in adolescents. Particularly, the muscle strength and cardiac endurance of female adolescents were lower than those of male adolescents.
Effects of Aerobic Exercise Training on Mitochondrial Ca2+ Homeostasis and Apoptosis in the Hippocampus of Type 2 Diabetic Rats
Authors: Park Se-Hwan , Yoon Jin-Hwan
Published: June 2021

PURPOSE: Type 2 diabetes mellitus (T2DM) is a recognized risk factor for neurodegenerative diseases such as Alzheimer’s disease (AD). Mitochondrial dysfunction caused by disturbance of calcium (Ca2+) homeostasis might be a pathophysiological link between T2DM and AD. In the present study, we investigated the effects of aerobic training on the regulation of mitochondrial calcium homeostasis, mitochondrial function (O2 respiration), and apoptosis in the hippocampus of T2DM rats.METHODS:Thirty male Otsuka Long-Evans Tokushima Fatty rats were divided into three groups: control group (CON, n=10), diabetes control group (DM, n=10), and diabetes+aerobic exercise group (DM+EXE, n=10). The rats in the exercise group were forced to run on a treadmill for 30 min, three times a week for 8 weeks.RESULTS:The DM group showed significantly increased mitochondrial calcium uniporter (MCU) protein and apoptosis-related factors such as Bax and caspase-3 and decreased mitochondrial O2 respiration when compared with the CON group. However, the hippocampus of rats in the DM+EXE group exhibited a significant decrease in MCU, Bax, and caspase-3 levels and an increase in Bcl-2 and mitochondrial O2 respiration when compared with the DM group.CONCLUSIONS:These results suggest that regular aerobic exercise alleviates mitochondrial dysfunction and apoptosis by modulating MCU, which is involved in mitochondrial Ca2+ homeostasis in the early stages of T2DM. This might be a potent strategy to prevent neurodegenerative diseases.
Acute Effect of Moderate-Intensity Aerobic Exercise on Arterial Stiffness in Fine Particulate Matter Environment: A Pilot Study
Authors: Kim Jin-Su , Hwang Moon-Hyon
Published: June 2021

PURPOSE:This study aimed to examine the effect of one bout of moderate-intensity aerobic exercise on arterial stiffness under ambient fine particulate matter (PM2.5) exposure.METHODS: In a randomized crossover design, seven healthy young men performed 30 minutes of treadmill running at 70% of heart rate peak under high PM2.5 and low PM2.5 exposure. Arterial stiffness was assessed by measuring the carotid-femoral pulse wave velocity and augmentation index, a measure of pulse wave reflection before and after each exercise intervention.RESULTS: Regardless of the PM2.5 exposure, brachial systolic blood pressure and heart rate increased in response to one bout of moderate-intensity aerobic exercise (p<.05). However, the augmentation index adjusted at a heart rate of 75 beats/min, central diastolic blood pressure, central mean arterial pressure, and brachial diastolic blood pressure were increased after one bout of moderate-intensity aerobic exercise under the high PM2.5 condition (p<.05).CONCLUSIONS: Moderate-intensity aerobic exercise at the high PM2.5 level may result in acute negative arterial stiffness and blood pressure responses even in healthy young men.

Published: June 2021

PURPOSE: This study aimed to compare the effects of low-volume and high-volume sled-push resistance training on muscle strength, power, and body composition.METHODS: Twenty-four college students were recruited and matched based on baseline one-repetition maximum (1-RM) into one of the three groups: 1) low volume (LV) resistance training, 2) high volume (HV) resistance training, or 3) control (CON) (n=8 per group). The LV training consisted of five single repetitions of pushing a weighted sled for 9.1 m. The HV training consisted of three sets of five repetitions of pushing a weighted sled for 9.1 m. Training consisted of three weekly workouts performed on nonconsecutive days for 6 weeks. This study utilized a pre-test and post-test design consisting of 1-RM, Wingate power test, standing long jump, vertical jump, and body composition.RESULTS: After 6 weeks of training, there was a similar but significant increase in 1-RM in both training groups (pre-test: LV=226.8±14.8 kg vs. HV=217.7±19.5 kg; post-test: LV=298.5±15 kg vs. HV=286.9±16 kg, p<.001). However, no improvements were observed in the Wingate power test, standing long jump, vertical jump, or body composition in both training and CON groups (p>.05).CONCLUSIONS: The results suggested that low-volume resistance training was as effective as a high-volume protocol for improving muscle strength. However, the present study was unable to determine the effects on muscle power and body composition.
Plant age, crop stage and surrounding habitats: their impact on sucking pests and predators complex in cotton (Gossypium hirsutum L.) field plots in arid climate at district Layyah, Punjab, Pakistan
Authors: Nadeem A. , Tahir H. M. , Khan A. A.
Published: June 2021

Abstract Sucking pests are major threat to cotton field crop which cause unbearable losses to the crop yield. Aim of the current study was to record seasonal dynamics of major sucking insect pests including whitefly, jassid, thrips and their natural arthropod predators i.e. green lacewings and spiders in cotton field plots. The effects of surrounding field crops on pests’ density and predatory efficiency of predators were also recorded. For sampling and survey of insects, the visual counting was found to be the most efficient method for recording the abundance of insects, trailed by net sweeping and tapping. Whitefly was the most dominant sucking pest found on the vegetative stage of cotton, followed by jassid and thrips. Fluctuated populations of predatory arthropods, spiders and green lacewings were also recorded during whole cropping season however, the densities of pests and predators varied with crop phenology. Spiders’ population was encouraging at both vegetative and flowering stage and also the same trend of jassid and whitefly were observed at both stages of the crop. Surrounding habitats showed non-significant effect on population densities of insect pests and predators. For abiotic factors, the spiders showed strong positive correlation with humidity and temperature. However, green lacewing was only positively correlated with humidity. On the other hand, the populations of whitefly, jassid and thrips showed non-significant correlation with both temperature and humidity. Overall densities of sucking insect pests were found above economic threshold level. The plant age, crop stage and surrounding habitats effect on the population fluctuation of pests as well as the predators’ abundance. The future studies are also warranted to investigate the altered habitats and multiple trap cropping to find out their impact on unattended insect predators and parasitoids in cotton crop.

Published: June 2021

Abstract Artemisia is one of the biggest genera in the family Asteraceae, with around 500-600 taxa at specific and sub-specific levels and organised in 5 subgenera. Due to the high number of taxa, a lot taxonomists are trying to solve the problem of its classification and phylogeny but its natural classification still hasn’t been achieved. In this research, 60 individuals belonging to 4 taxa of the subgenus Dracunculus of Artemisia L. in Turkey were examined. For all the examined individuals from both the same and different populations belonging to the taxa of the subgenus Dracunculus, the sequences of the regions both psbA-trnH of chloroplast DNA and ITS of nuclear DNA were determined. Also, the gene regions obtained were recorded in the NCBI GenBank database and an accession number was taken. It was found that there was no gene flow and hybridization between the four studied taxa of the subgenus Dracunculus, and these 4 taxa also completed their speciation. According to the results of this molecular study, A. campestris var. campestris, A. campestris var. marschalliana and A. campestris var. araratica were proposed to be raised from the variety level to the species level. This research is important as it is the first molecular based study relating with the subgenus Dracunculus growing in Turkey.

Published: June 2021

Abstract Myxosporidiosis is an infectious disease caused by myxozoans of the Phylum Cnidaria, Class Myxosporea, and Order Bivalvulida, considered a common parasite in fresh and saltwater fishes that parasitize many organs, especially gills. In the present study, 49 specimens of fishes belonging to eight genera: Tetragonopterus, Leporinus, Myleus, Pirinampus, Rhapiodon, Pygocentrus, Ageneiosus, and Serrasalmus were collected and blood smears were made, fixed with absolute methanol, and stained with Giemsa 10% to survey hemoparasites. However, myxospores were found in the circulating blood of five (10.20%) fishes belonging to genus Tetragonopterus, Myleus, and Pygocentrus. Two morphological types of Myxobolus spp. were identified in all the five fish specimens analyzed. Usually, investigations on myxozoans in fish are carried out with the search for plasmodia or cysts in the fish organs and observation of the cavity of organs. Nevertheless, this study highlights the importance of also examining the blood of these animals, since these parasites can cause severe pathogenic diseases in fish. Thus, the blood analyses can proportionate preventive sanitary control for commercial fish avoiding economic loss.

Published: June 2021

Abstract The influence of pharmaceutical residues and heavy metals on living organisms has received global attention. The present study assessed the interactive effect of antibiotic residues and heavy metals in soil, as contaminated food with cadmium (Cd) and oxytetracycline (OTC) on the isopod Porcellio leavis. It was fed on fresh plant leaves contaminated with different concentrations of cadmium, Cd+OTC1000 ppm, Cd+OTC2000 ppm and Cd+OTC3000 ppm for 4 weeks. The changes in the feeding patterns, protein, lipid peroxidation (LPO), catalase activity (CAT), and total free amino acids (TFAA) were recorded. There were significant differences in the obtained results where Cd reduced the egestion ratio (ER) however, OTC enhanced this ratio. Biochemical analysis illustrated that combination between OTC and Cd inhibits the toxic effects of Cd at low concentration (1000 ppm), while at high concentration (3000 ppm) raise the toxicity. Detailed studies are required for further understanding of the interaction between OTC and heavy metals, and also its impact on soil animals and for improving soil risk evaluation.

Resumo Este artigo propõe perscrutar pela exterioridade das relações seriais o fenômeno aprender, no sentido de tensionar o campo didático para além do fenômeno instrução, ensino intencional, que se realiza em circunstâncias bem características e delimitadas – as quais são denominadas de ensino escolar. Envolto nesse problema do fenômeno aprender, revistaremos o livro Proust e os signos, no intento de aí flagrar como os signos proustianos nos abrem diferentemente à aprendizagem infinitesimal pelas repetições materiais e espirituais, diferindo no tempo.

Abstract: Introduction: Basic Life Support (BLS) refers to the procedures that must be performed in situations of cardiorespiratory arrest or airway obstruction, and therefore, undergraduate students and health professionals must be highly trained to perform. Objective: To determine the level of knowledge about Basic Life Support (BLS) and the associated factors among undergraduate students from the health area in their last year of school in a public university. Methods: This is a cross-sectional study with undergraduate students in Physical Education, Nursing, Pharmacy, Medicine and Dentistry at the Universidade Estadual de Ponta Grossa, Brazil. Data collection was carried out in 2019, in the last month of course completion, by a trained researcher using a self-administered questionnaire containing sociodemographic data, professional training, perceived self-knowledge and a validated BLS instrument. There was an association between the outcome “undergraduate students’ knowledge” dichotomized as high (≥70% correct) or low level (<70% correct) and the independent variables (sociodemographic data, professional training and perceived self-knowledge) and the performance of the binary and multinomial logistic regression (p<0.05). Results: 191 undergraduate students participated in the study, being 85.6% of the chosen universe. A total of 30 participants (15.7%) had a high level of knowledge on BLS, being students from the Nursing (n = 12) and Medicine (n = 18) courses. While 35.3% of Nursing students and 46.2% of Medicine students had a high level of knowledge about BLS, there were no students from the Physical Education (0.0%), Pharmacy (0.0%) and Dentistry (0.0%) courses. In the crude analysis, the low level of knowledge was associated with younger age (OR=2.75, 95%CI:1.22-6.21), not feeling safe to perform BLS (OR=3.12, 95%CI:1.38-7.01) and the fact that the discipline was not part of the undergraduate course (OR=18.35, 95%CI:2.44-138.1). In the adjusted analysis, the fact that the discipline was not part of the undergraduate course (OR=13.41, 95%CI:1.74-103.12) remained. Conclusion: Most students had a low level of knowledge about BLS, and only students from the Medicine and Nursing courses demonstrated a high level of knowledge. After adjustment, the fact that the discipline was not part of the undergraduate course was associated with a lower level of knowledge about BLS.
The geography of the nationalist right in Portugal: outlines of an emerging process
Authors: Madeira Paulo Miguel Fernandes , Silva Katielle Susane do Nascimento , Malheiros Jorge Silva Macaísta
Published: June 2021

Resumo A emergência da direita nacionalista em Portugal nas eleições legislativas de 2019 é aqui contextualizada nos fenómenos populistas europeus do mesmo tipo nas décadas mais recentes e na geografia do descontentamento que lhes está associada. A análise da territorialização da votação nesse novo partido, o Chega, na escala municipal, apresenta um padrão que não se coaduna com o que tem sido a geografia eleitoral em Portugal desde a Revolução Democrática de 1974, sugerindo as correlações com um conjunto alargado de variáveis com uma forte motivação identitária da sua base eleitoral, que aparece associada a alguns elementos de desvantagem social e económica. Simultaneamente, a sociologia dos eleitores do Chega apresenta alguns aspetos surpreendentes em face do que se sabe para a generalidade dos casos europeus.
Political interests in the creation process of the Metropolitan Region of Umuarama, State of Paraná
Authors: Oliveira Renato Alves de , Borges William Antonio
Published: June 2021

Resumo Neste trabalho, buscou-se construir uma inteligibilidade sobre os interesses políticos inscritos no processo de criação da Região Metropolitana de Umuarama (RMU). Para tanto, a pesquisa mobilizou a legislação vigente, o Estatuto da Metrópole, base jurídica para a dinâmica metropolitana e que estabelece critérios para a instituição de novas RMs. O percurso teórico abordou a literatura referente à questão metropolitana no Brasil e sobre o processo de políticas públicas. A metodologia empregada envolveu pesquisa documental e pesquisa de campo realizadas por meio de entrevistas semiestruturadas. Como resultado, a narrativa construída conta-nos que a decisão de criação da RMU foi baseada em interesses políticos, vinculados ao status de pertencer a uma RM, interesses imobiliários e eleitoreiros.
The Right to the City and the public sphere: between political participation and the renewal of the legal urbanistic order
Authors: Prist Arthur Hirata , Bucci Maria Paula Dallari
Published: June 2021

Resumo Este artigo propõe uma análise dos aspectos políticos e jurídicos do Direito à Cidade sob a perspectiva do conceito de esfera pública. O Direito à Cidade é interpretado como um elo dinâmico entre a mobilização política, a democratização das relações sociais e do aparato institucional do Estado e a garantia de melhores condições materiais de existência no espaço urbano. A partir da revisão bibliográfica sobre o tema das lutas sociais urbanas no Brasil e na cidade de São Paulo, pretende-se demonstrar que o Direito à Cidade é exercido pela população a partir dos embates na esfera pública responsáveis por impulsionar a renovação da ordem jurídica e atribuir novos sentidos ao Direito existente.
População de rua e cidade: uma análise da ressignificação dos espaços urbanos
Authors: Dantas Lucas Eduardo Lima
Published: June 2021

Resumo As investigações propostas neste artigo pretendem refletir acerca da relação entre a População em Situação de Rua (PSR) e o espaço urbano, levando em consideração as significações e os conflitos produzidos sobre o tecido urbano por esse grupo. Buscar-se-á, portanto, entender a maneira como o indivíduo se relaciona com o espaço através da sua caminhada e das novas significações que produz sobre o ambiente que ocupa. Para entender tal lógica, recorre-se a uma discussão histórica para entendermos o modelo urbano da cidade atual, desde sua disposição espacial ao surgimento de seus problemas sociais.

Lutando por novas narrativas em favelas e periferias: cidadanias complexas em meio a ativismos materiais e culturais
Authors: Comelli Thaisa Cristina
Published: June 2021

Resumo O presente artigo tem como objetivo debater e explorar os novos ativismos em favelas, cujo foco se posiciona na história, na cultura e na identidade desses territórios. Argumentamos aqui que, diferentemente do tradicional ativismo urbano comumente abordado na literatura (focado em demandas de natureza material), os novos ativismos buscam adicionar, a essas lutas, uma disputa pela narrativa sobre o território. Exploramos essas manifestações à luz de debates sobre a transição conceitual da cidadania e sobre identidades interseccionais. Especialmente, questionamos a existência de uma suposta identidade de favelado na qual os discursos e narrativas hegemônicas sobre a cidade, ora podem ser reproduzidos, ora podem ser subvertidos e utilizados na construção de lutas e ativismos urbanos insurgentes.
ESPECIAL 60 ANOS DA RAE: DE ESTRELA SOLITÁRIA NO PASSADO AOS DESAFIOS FUTUROS

Published: June 2021

RESUMO Este texto apresenta os artigos convidados para esta edição especial de comemoração dos 60 anos da Revista, com o objetivo de refletir sobre o passado, o presente e o futuro da RAE-Revista de Administração de Empresas e das revistas científicas brasileiras em Administração. Apresenta-se, em primeiro lugar, o papel histórico da Revista na construção da academia brasileira em Administração, bem como seu impacto em várias gerações de pesquisadoras e pesquisadores no País. Num segundo momento, são abordados os principais problemas enfrentados na RAE e seus desafios futuros que podem, eventualmente, ser úteis para os demais periódicos brasileiros no campo da Administração. Conclui-se que a redução das desigualdades entre os periódicos nacionais e internacionais pode ser encampada como uma bandeira da RAE e de periódicos brasileiros, valendo-se de ventos favoráveis como os Objetivos de Desenvolvimento Sustentável da Organização das Nações Unidas (ONU), o movimento Declaration on Research Assessment (DORA) e a potencialidade de avaliação do impacto social das instituições e seus programas por parte de entidades acreditadoras. Mas contar com que esses ventos favoráveis façam o trabalho sozinhos seria uma ilusão, portanto há um longo trabalho de protagonismo pela frente.

DEPOIS DO CAPITALISMO, O GERENCIALISMO DEMOCRÁTICO
Authors: Bresser-Pereira Luiz Carlos
Published: June 2021

RESUMO A partir do final dos anos 1970, o capitalismo experimentou uma fase regressiva - o capitalismo neoliberal financeiro-rentista - e, desde 2008, entrou em crise terminal. Os capitalistas deixaram de controlar o processo de acumulação de capital e inovação que os legitimava, e o capitalismo deixou de produzir desenvolvimento econômico e progresso humano. Em seu lugar, está surgindo uma nova organização social, que o autor denomina "gerencialismo democrático", no qual a classe dos gerentes ou tecnoburocratas voltou a se fortalecer e a constituir o núcleo da nova coalisão de classes dominantes. Ao mesmo tempo, a democracia vem enfrentando bem o desafio autoritário, e é possível prever que ela se aprofundará no gerencialismo democrático.
