Ley de la naturaleza y ley natural de la res publica en la relectura ciceroniana del conocimiento de sí
Authors: Corso de Estrada Laura
Published: December 2021

En el presente artículo la autora considera como temática central la significación de la concepción de M. Tulio Cicerón sobre el conocimiento de sí en la teoría filosófico-política del autor. Con este cometido justifica la aportación de la elaboración ciceroniana sobre el tema como relectura de la tradición socrático-platónica en el ámbito de la filosofía romana, examinando sus componentes propios. Así, la autora desarrolla una exégesis acerca de las notas de la concepción ciceroniana sobre el conocimiento de sí en De republica, De legibus, De finibus bonorum et malorum, Tusculanae disputationes y lugares paralelos, con el objeto de ponderar su mediación en la constitución de la comunidad política. En este contexto la autora examina el papel de la ley natural en el desenvolvimiento del conocimiento de sí mismo y en el develamiento de la comunidad humana.
Memórias de um sargento de milícias: ninguém aprende samba no colégio
Authors: Bonifácio Leite Carlos Augusto
Published: December 2021

Este artigo sugere a hipótese de lermos Memórias de um sargento de milícias como um romance de formação para o homem livre remediado carioca de meados do século XIX. Para isso, contudo, recupera o ensaio de referência de Antonio Candido, “Dialética da malandragem”, para argumentar que o crítico sobrepõe um malandro posterior, construído na cultura brasileira a partir dos anos 1920/1930, ao capadócio, também presente no romance, mas não como personagem principal. Se prospera a leitura de um romance de aprendizagem, o que estaria aprendendo o leitor “brasileiro” de então? Como se distanciam a formação do indivíduo burguês representada em narrativas do centro do capitalismo, mormente Inglaterra e França, e a formação do homem livre representada na periferia do capitalismo?
“Segundo as leis da beleza”: evolução e elevação em um soneto de Antero de Quental
Authors: De Oliveira André Luis , Dos Reis Corrêa Ana Laura
Published: December 2021

Neste artigo, analisamos o soneto “Evolução” (1886), do poeta português Antero de Quental, considerando o momento de sua produção, quando o tema da evolução não só já havia posto à prova sistemas filosóficos, postulados religiosos e convenções sociais, como já recebera uma interpretação político-filosófica que se tornara hegemônica na segunda metade do século XIX, o darwinismo social. Nessa configuração determinada, o soneto aqui analisado, assim como muitos outros da obra de Quental, parece caminhar na direção contrária a essa tendência naturalista. Investigamos aqui as razões para tal dissonância entre o poema e sua época, apostando na hipótese de que o tema da evolução, no soneto de Antero, é composto artisticamente “segundo as leis da beleza” (Marx, 2004) e, por essa razão, escapa do idealismo e do naturalismo, elevando a evolução a sua real dimensão histórica.

Learning Data Correction for Myoelectric Hand Based on “Survival of the Fittest”
Authors: Yamanoi Yusuke , Togo Shunta , Jiang Yinlai , Yokoi Hiroshi
Published: December 2021

In recent years, myoelectric hands have become multi-degree-of-freedom (DOF) devices, which are controlled via machine learning methods. However, currently, learning data for myoelectric hands are gathered manually and thus tend to be of low quality. Moreover, in the case of infants, gathering accurate learning data is nearly impossible because of the difficulty of communicating with them. Therefore, a method that automatically corrects errors in the learning data is necessary. Myoelectric hands are wearable robots and thus have volumetric and weight constraints that make it infeasible to store large amounts of data or apply complex processing methods. Compared with general machine learning methods such as image processing, those for myoelectric hands have limitations on the data storage, although the amount of data to be processed is quite large. If we can use this huge amount of processing data to correct the learning data without storing the processing data, the machine learning performance is expected to improve. We then propose a method for correcting the learning data through utilisation of the signals acquired during the use of the myoelectric hand. The proposed method is inspired by “survival of the fittest.” The effectiveness of the method was verified through offline analysis. The method reduced the amount of learning data and learning time by approximately a factor of 10 while maintaining classification rates. The classification rates improved for one participant but slightly deteriorated on average among all participants. To solve this problem, verifying the method via interactive learning will be necessary in the future.

МОТИВАЦІЯ НАЗВ БРИТАНСЬКИХ ТЕЛЕВІЗІЙНИХ ПРОГРАМ
Authors: Зосімова О. В. , Лісна О. І.
Published: December 2021

У статті розглянуто основні типи мотивації назв британських телевізійних програм. З’ясовано, що найпродуктивнішою є сутнісна мотивація, тобто найбільш поширені назви, які прямо чи опосередковано відображають зміст, указують на жанр або формат телепередачі. Досліджувані телевізіоніми також мають посесивну, локативну, темпоральну й асоціативну мотивації. Символічні назви трапляються досить рідко. Незалежно від типу мотивації, у процесі творення телевізіонімів широко використовують найрізноманітніші стилістичні засоби, що мають зробити назву оригінальною, привабливою та легкою для запам’ятовування.
СИСТЕМАТИЗАЦІЯ ТЕРМІНІВ У ПРОЦЕСІ ПРОФЕСІЙНОЇ МЕДИЧНОЇ КОМУНІКАЦІЇ
Authors: Заліпська І. Я.
Published: December 2021

У статті проаналізовано сучасну наукову літературу, що розглядає особливості функціонування та етапи вивчення медичної термінології в лінгвістичній науці. Аргументовано актуальність та перспективність дослідження зазначеної проблеми. Під медичною термінологією розуміємо терміносистему, що відповідає галузі знань «Медицина» загалом, і сукупність лексем, які описують та позначають частини, органи, процеси людського організму зокрема. Джерельною базою дослідження слугували лексеми на позначення сучасних українських медичних термінів. У науковій студії проаналізовано медичний термін як одиницю української терміносистеми в процесі професійного спілкування лікаря з пацієнтом. Розглянуто особливості професійної діяльності лікаря в медичному дискурсі. Схарактеризовано принципи класифікації медичних термінів. Наголошено, що під час професійної комунікації лікаря з пацієнтом частотність уживання конкретних медичних термінів відрізняється від інших типів спілкування. Виокремлено такі тематичні групи медичних термінів: назви захворювань, лексеми на позначення симптомів хвороб та їхніх ознак, назви органів (анатомічні терміни), назви інструментів і приладів, терміни на позначення методів діагностики, назви відділень медичних закладів. Встановлено, що ефективне спілкування характеризується спільною метою, довірою, повагою та співпрацею лікаря з пацієнтом. Важливими засобами цього є використання зрозумілої пацієнтові медичної термінології, а також дотримання правил етикету спілкування та загальних правил поведінки. Аргументовано значущість теми наукової студії в опануванні фахової термінології в процесі спілкування «лікар – пацієнт». Проблеми формування, функціонування та розвитку медичних термінів потребують розробки єдиної концепції термінотворення з урахуванням досвіду та позитивних досягнень науковців різних поколінь. Систематичне вивчення сучасної української медичної термінології може покращити та систематизувати знання в цій сфері.

Published: December 2021

У науковому доробку відомого українського лінгвіста Галини Прокопівни Їжакевич стилістика посідає особливе місце й пов’язана з вивченням взаємовпливу української та російської мов. Однак проблематика стилістичних праць спрямована не лише на вивчення мовної взаємодії, а насамперед на збагачення однієї мови засобами іншої. У вивченні мови українських та російських класиків Г. П. Їжакевич убачала великий сенс і неодноразово зверталася до цього питання. Творчість М. В. Гоголя цікавила її в аспекті оновлення української і російської мов експресивно-стилістичною лексикою та фразеологією. Новаторське поєднання двох мовних стихій в одному вислові українським письменником, що писав російською, розширювало уявлення про межі літературної мови й розкривало творчі потенції кожної з мов.

Counselling Students’ Perception of Online Learning during COVID-19 in Malaysia
Authors: Nazilah A.
Published: December 2021

The COVID-19 pandemic is of global proportions affecting Higher Education Institutions (HEIs), with online learning becoming a prominent approach to students’ learning during the pandemic. However, minimal attention has been paid to researching online learning in Malaysia during COVID-19. This cross-sectional study examines students’ perceptions of online learning during the pandemic. A sample of 457 counselling students has been chosen using purposive sampling. Online questionnaires in Google Forms with an appended consent form were distributed to the respondents via WhatsApp with 184 respondents and a response rate of 40.3 per cent. The online questionnaire comprised demographic, students’ perception towards online learning (a closed-ended question), reasons for liking and disliking online learning (two closed-ended questions), their preferable online teaching material and delivery (a closed-ended question), and suggestions to overcome online learning constraints (an open-ended question). Data collection was carried out in approximately two weeks and analysed using descriptive statistics. The results showed that the majority of respondents (84.8%) decided that the online learning approach was essential during the pandemic. Most students liked online learning because learning can continue even during the pandemic (75.7%), it was safer to study at home than to go to campus (63.0%), and it facilitated meeting the requirements to graduate on time (44.5%). Most disliked online learning because doing group assignments online was difficult (60.3%), attending online classes was challenging (59.8%), and taking an online test was challenging (55.3%). The respondents (50.0%) also acknowledged that the most effective teaching material and delivery tool for online learning was a PowerPoint with audio (asynchronous method). The respondents recommended internet stability and speed improvements, and a convenient space for studying online at home. This study contributes to the theory and evidence necessary for future research, programmes, and interventions to promote a fully digitally connected and informed society.
An Analysis of Students’ Perception of Online Assessments and its Relation to Motivation Towards Mathematics Learning
Authors: Valdez Ma. Theresa Christine C. , Maderal Lea D.
Published: December 2021

Assessing student performance is a challenge faced by most educational institutions during this time when conducting in-campus classes is affected by the pandemic. Use of online assessments to determine student performance is gaining wider acceptance over the traditional paper-and-pen type as it allows evaluation of what the students learned despite the lack of physical classroom interaction. Although there are studies that examine student perceptions about online learning in general, only a few focus on assessments especially those that consider its relation to affective aspects of learning. The views of students being the primary beneficiaries of the technology would give relevant information in designing appropriate online assessments and can bring about the success of its implementation. Thus, this present study investigated the usefulness of online assessments according to the perspective of students particularly in their math subject and its relation to their motivation towards mathematics learning. A mixed methods research design was conducted to determine the perception and motivation of 127 second year level engineering students via a questionnaire survey after exposure to a set of online assessments. Results showed that students have a high level of motivation towards mathematics learning and have positive perception about online assessments. Using factor analysis, variations in the perception were found to be explained by 4 factors focused on ease of use and functionality, personal preference, technical considerations, and complementation with other methods. Some of these factors were found to be significantly related with various aspects of motivation. Interview of students also revealed they found taking online assessments a positive innovation in giving assignments and prefer them over traditional assignments. The findings derived from this study give teachers a basis in designing more effective online assessments particularly those that address the needs of today’s generation of learners. Further, for a developing country like the Philippines, findings of this study would greatly contribute to the government and academic sector’s efforts in capacity building of its online system of education.
Contextualizing Social Media Ecology and Its Pedagogical Affordances: The Perspective of High School Teachers
Authors: Otchie Wilson O. , Pedaste Margus , Bardone Emanuele , Chounta Irene-Angelica
Published: December 2021

The potential of social media technology has made its use a daily habit among individuals, institutions, and communities. However, several studies on technology adoption, especially social media use in education, focus more on its impact on the student than the teacher, who is generally perceived as a key stakeholder. This study used purposive sampling to select teachers who taught grades 7–10 and had used social media in their teaching activities. In-depth interviews were carried out with participating teachers to get their opinions and perspectives about how they used social media in their teaching activities (N=11). Inductive and deductive coding were used for the latent content analysis and four categories emerged: (1) SM technology in the classroom, (2) positive perceived contextual affordances, (3) negative perceived contextual affordances, and (4) support for social media. Results of the study show that, besides the schools’ learning management systems, YouTube was the major SM app that was regularly used by participants in their lessons. Also, all participating teachers expressed their interest in teaching with social media. However, they cited some challenges as weaknesses towards social media use in teaching.
Exploring Feedback and Gamification in a Data Modeling Learning Tool
Authors: Dæhli Olav , Kristoffersen Bjørn , Lauvås jr Per , Sandnes Tomas
Published: December 2021

Data modeling is an essential part of IT studies. Learning how to design and structure a database is important when storing data in a relational database and is common practice in the IT industry. Most students need much practice and tutoring to master the skill of data modeling and database design. When a student is in a learning process, feedback is important. As class sizes grow and teaching is no longer campus based only, providing feedback to each individual student may be difficult. Our study proposes a tool to use when introducing database modeling to students. We have developed a web-based tool named LearnER to teach basic data modeling skills, in a collaborative project between the University of South-Eastern Norway (USN) and Kristiania University College (KUC). The tool has been used in six different courses over a period of four academic years. In LearnER, the student solves modeling assignments with different levels of difficulty. When they are done, or they need help, they receive automated feedback including visual cues. To increase the motivation for solving many assignments, LearnER also includes gamifying elements. Each assignment has a maximum score. When students ask for help, points are deducted from the score. When students manage to solve many assignments with little help, they may end up at a leaderboard. This paper tries to summarize how the students use and experience LearnER. We look to see if the students find the exercises interesting, useful and of reasonable difficulty. Further, we investigate if the automated feedback is valuable, and if the gamifying elements contribute to their learning. As we have made additions and refinements to LearnER over several years, we also compare student responses on surveys and interviews during these years. In addition, we analyze usage data extracted from the application to learn more about student activity. The results are promising. We find that student activity increases in newer versions of LearnER. Most students report that the received feedback helps them to correct mistakes when solving modeling assignments. The gamifying elements are also well received. Based on LearnER usage data, we find and describe typical errors the students do and what types of assignments they prefer to solve.

Published: December 2021

Cardiovascular pathology is one of the frequent comorbidities in patients with chronic obstructive pulmonary disease, due to both genetic predisposition and common risk factors (smoking, senile age, male gender, sedentary lifestyle, obesity). The article shows that development of endothelial dysfunction is one of the earliest phases of pathogenesis in this setting. Endothelial dysfunction mechanisms are defined and characterized, including an imbalance of vasoconstricting and vasodilating agents with the emergence of "vicious circles" that violate hemo-vascular homeostasis. The role of nitric oxide, endothelin-1, intercellular adhesion molecule-1 (ICAM-1) in the development of endothelial dysfunction in COPD patients is discussed.

The article defines the concept of oxidative stress, the most potent oxidants and mechanisms of their damaging effect arebeing listed. A particular attention is paid to 8-isoprostane as a golden standard in assessment of oxidative stress in patients with COPD.

Considering the MRI indications of the elements of the cerebrospinal fluid system of children is important for the development of neurology and neurosurgery, it is necessary to consider gender differences in the brain size and structure.

Objective To study the sex differences in the structure of the cerebrospinal fluid system in seven-year-old children.

Material and Methods For the study, archival data on the sizes of the lateral ventricles of the brain of 120 children aged 7 (60 boys and 60 girls) were involved, in particular: 1) the length of the anterior horn; 2) the width of the anterior horn; 3) the length of the central part; 4) the width of the central part; 5) the length of the posterior horn; 6) the width of the posterior horn; 7) the length of the lower horn; 8) the anteroposterior size; 9) the distance between the anterior horns; 10) the distance between the posterior horns; 11) the length of the third ventricle; 12) the height of the third ventricle; 13) the length of the aqueduct; 14) the length of the fourth ventricle; 15) the height of the fourth ventricle. The studies were carried out using the method of magnetic resonance imaging. Quantitative indicators were assessed for compliance with the normal distribution using the KolmogorovSmirnov test. The accumulation, correction, systematization of the initial information were carried out in Microsoft Excel 2016. Statistical analysis was carried out using the Statistica 10.0 software (StatSoft Inc., USA). The results were considered statistically significant at p < 0.05.

Results The data obtained in the study of the cerebrospinal fluid system in children during their pre-school period of childhood are indicators of the norm and can be used for diagnostic studies in the departments of radiation diagnostics. The bilateral asymmetry of the lateral ventricles of the brain in pre-school children, discovered during the work, is of crucial clinical significance. The morphometric indicators of the elements of the cerebrospinal fluid system should be considered by specialists in the study of brain neuroplasticity.

Conclusion Analysis of the obtained in vivo encephalometric data indicates the presence of sexual variability of the brain and parameters of the structures of the cerebrospinal fluid.

Aim 1) To develop normative values of global and regional left ventricular longitudinal deformation (LVLD) during real time three-dimensional stress echocardiography with adenosine triphosphate (ATP) and utilization of automated function imaging technology (4D Stress-Echo + LVLD with ATP); 2) to compare the effectiveness of detection of symptom-related coronary arteries during 4D Stress-Echo with ATP using: a) traditional visual assessment of regional myocardial contractility and b) step-by-step analysis of segmental LVLD.

Material and Methods 15 healthy subjects and 32 patients with coronary artery disease (CAD) were examined after coronary angiography. All individuals underwent 4D Stress-Echo + LVLD with ATP (Vivid E95, General Electric).

Results The normative values of global LVLD at three stages of the pharmacological stress-test (before, during and after ATP infusion) were –19.5 (95% CI: -20.4 – -19.0), –21.6 (95% CI: -22.8 – -20.4) and –19.5 (95% CI: -20.3 – -18.6), respectively; the values of LVLD in each of the 17 segments of left ventricular myocardium in healthy subjects were also determined. In patients with CAD visual control of contractility during stress test revealed dynamic decrease in local thickening of the myocardium, appearance of new zones of contractility disorders and expansion of previously noted in 31.2% of cases, while analysis of deformation detected the appearance of new zones of deformation disturbances and expansion of previously found – in 68.7% (р = 0.0055). Stress-induced worsening of myocardial deformation during ATP infusion in the zones of blood supply of left anterior descending coronary artery, circumflex artery and right coronary artery (with presence of hemodynamically significant stenoses and occlusions detected during coronary angiography) were found in 28.0, 77.7 and 65.2% respectively (р1-3 = 0.0194; р1-2 = 0.0019; р2-3 = 0.2864).

Conclusion The normal values of global and segmental LVLD for each stage of 4D Stress-Echo + LVLD with ATP were determined. 4D Stress-Echo + LVLD with ATP can significantly increase the effectiveness of symptom-related coronary arteries identification in patients with CAD in comparison with traditional Stress-Echo with visual assessment of local myocardial contractility.

Objective To determine the ratio of the main growth factors when using various methods of local stimulation of reparative osteogenesis.

Material and methods The study consisted of two parts: in the first part a comparative analysis of the content of growth factors by ELISA was carried out (PDGF – platelet derived growth factor, TGF – transforming growth factor, VEGF – vascular endothelial growth factor, IGF – insulin-like growth factor, BMP6 and BMP7 – morphogenetic proteins 6 and 7), capable of stimulating reparative osteogenesis in blood plasma, plateletrich plasma, red bone marrow and bone autoregenerate. The second part presented the results of approbation of the autoregenerate obtained according to the original method in the framework of an acute experiment on animals.

Results The most important cytokines affecting the process of reparative osteogenesis are fibroblast growth factor – FGF1 and bone morphogenetic protein 7 – BMP7. Based on the results of a comparative enzymelinked immunosorbent assay, it has been established that the autoregenerate, obtained by the original method, and a bone marrow aspirate concentrate have the highest osteogenic potential.

Conclusion Autoregenerate is an effective and promising means of local stimulation of reparative osteogenesis, and its transplantation is a simple and highly effective procedure.
Biomarkers of heart failure: current state of problem

Published: December 2021

There is constant increase in patients with heart failure every year worldwide. Early diagnosis and prediction of deterioration could upgrade management of patients and slow down the progression of heart failure.

The brain natriuretic peptide precursor (NT-proBNP) is considered to be the universal biomarker, although it has several limitations. The search of ideal biomarker is directed into molecular biology and genetics. Microribonucleic acids (microRNAs) regulate different processes in human body, present myocardial specificity, and plasma stability. It has been proven in different trials that diagnostic and prognostic level of microRNAs is equal to NT-proBNP. Potential opportunities of the method are not only diagnosis but therapeutic targets for heart failure

Authors: Sharp Kirsty-Lee , Synodinos Costa
Published: December 2021

Objective - The primary objective of this study is to identify and explain the antecedents of organic food purchase behaviour of Generation Y students in the South African context. This study aimed to shed some light on Generation Ystudents' health consciousness, perceived behaviour control, convenience, attitudes, purchase intentions, and actual buying behaviourtoward organic food products. The study also attempted to determine the underlying strengths and relationships between the constructs used in the measurement scale. Lastly, gender relationships were investigated to determine if any differences existed between males and females in terms of their organic food product purchases.

Methodology/Technique - This research study employed a descriptive, non-probability, convenience sampling design. The intended target population was full-time registered undergraduate Generation Y students aged between 18 and 24 years. The sample size was 200 students based across the four faculties within the chosen higher education institution, namely the Faculty of Management Sciences, the Faculty of Applied and Computer Sciences, the Faculty of Engineering, and the Faculty of Human Sciences. The 200 self-administered questionnaires were distributed during recess times as to not to disrupt any learning time. The questionnaire contained a cover letter explaining the purpose of the study and that participation in the study was completely voluntary.

Findings - The measurement scale displayed adequate reliability and validity for all constructs. Furthermore, all constructs had statistically significant positive means, indicating that Generation Y students are health-conscious, care for the opinions of friends and family, display pro-organic attitudes, intentions, and behaviour. Results from this study indicate that there is a need for food organizations to consider implementing organic-based products in their product offerings within the South African market.

Novelty - Investigation oforganic food product purchase behaviouramong South African Generation Y students (Consumer behaviour).

Specific features of the static calculation of underground pipelines of gravity wastewater disposal systems
Authors: Захаров Ю.С.
Published: December 2021

Необходимым условием экологически безопасной и надежной эксплуатации подземных трубопроводов самотечных систем водоотведения является определение требований к прочностным характеристикам элементов строительной конструкции (труб, фасонных частей), которые формируются на основании статического расчета трубопровода. При статическом расчете определяются и анализируются прямые и косвенные нагрузки, действующие на трубопровод, и производится оценка их влияния на конструкцию. Рассматриваются существующие подходы к выполнению статического расчета. На основании результатов исследований российских и зарубежных авторов утверждается, что выбор параметров труб, используемых при строительстве подземных трубопроводов, зависит не только от свойств конструкционных материалов, но прежде всего от свойств грунта, условий укладки и монтажа, а также от действующих нагрузок и степени деформации трубопровода.

An essential pre-requisite for environmentally safe and reliable operation of underground pipelines of gravity wastewater disposal systems is specifying the requirements for the structural behavior of building construction elements (pipes, fittings) that are determined on the basis of a static calculation of the pipeline. In the process of the static analysis, direct and indirect loadings acting on the pipeline are determined and analyzed, and their impact on the structure is estimated. Existing approaches to performing a static analysis are considered. Based on the results of the studies carried out by Russian and foreign authors, it has been argued that the choice of the pipe parameters used in the construction of underground pipelines depends not only on the properties of structural materials, but primarily on the soil properties, conditions of laying and installation, as well as on the existing loadings and degree of pipeline deformation.
