PERCEÇÕES DOS ESTUDANTES SOBRE O ESTÁGIO SUPERVISIONADO EM CONTEXTO DO ENSINO REMOTO
Authors: Mesquita Cristina , Teixeira Carlos , Pires Manuel Vara
Published: July 2021

Este estudo tem por objetivo principal analisar as perceções dos estudantes envolvidos em estágios sobre as competências, dificuldades, oportunidades e ameaças que sentiram em contexto de ensino remoto. Seguiu-se uma linha metodológica interpretativa, usando o questionário como técnica de recolha de dados. Para a interpretação e discussão dos dados utiliza-se uma análise estatística descritiva, para o conjunto das questões fechadas, e uma análise interpretativa, tipo análise de conteúdo, para as questões abertas. A análise de conteúdo permitiu criar categorias e subcategorias que foram analisadas de forma interpretativa. Da análise emerge a ideia de que deslocalização para o online permitiu, a alguns, continuar a manter o contacto com os grupos/turmas onde realizavam as suas práticas e recriar as estratégias de ensino-aprendizagem, a partir de outras ferramentas. Esta nova realidade expôs fragilidades socioeconómicas, destacando a desigualdade no acesso aos recursos, quer para os alunos da formação inicial, quer para as crianças da educação básica. Mostra, também, que processos de aprendizagem da profissão são processos complexos que necessitam de interações face a face e experienciais, mas que se podem configurar em outras formas de formação.

Published: July 2021

Background and Objective: Ectopic beats originating from the pulmonary
vein (PV) trigger atrial fibrillation (AF). The purpose of this study
was to clarify the electrophysiological determinant of AF initiation
from the PVs. Methods: Pacing studies were performed with a single extra
stimulus mimicking an ectopic beat in the left superior pulmonary veins
(LSPVs) in 62 patients undergoing AF ablation. Inducibility of AF,
effective refractory period (ERP) and conduction properties within the
PVs were analyzed. Results: A single extra stimulus in LSPV induced AF
in 20 patients (32% of all patients) at the mean coupling interval (CI)
of 172 ms. A CI-dependent anisotropic conduction at the AF onset was
visualized in a 3D-mapping. Onset of AF was site-specific with
reproducibility in each individual. Mean ERP in LSPV in the AF inducible
group was shorter than that in the AF non-inducible group (182 ± 55 ms
vs 254 ± 51 ms, P<0.0001). LSPV ERP dispersion was greater in
the AF inducible group than in the AF non-inducible group (45 ± 28 ms vs
27 ± 19 ms, P<0.01). Circumferential intra-PV conduction time
(IPVCT) exhibited decremental properties in response to shortening of
CI, and the prolongation of IPVCT in the AF inducible site was greater
than that in the AF non-inducible site (P<0.05) in each
individual. Conclusions: Location and coupling interval of an ectopic
excitation ultimately determine the initiation of AF from the PVs. ERP
dispersion and circumferential conduction delay may lead to anisotropic
conduction and reentry within the PVs that initiate AF.
Evaluation of temporomandibular disorder and oral parafunction prevalence in dental assistant students: A cross-sectional descriptive study
Authors: Öztürk Taner , Eraslan Ravza
Published: July 2021

Objective: This cross-sectional descriptive study aimed to determine the
prevalence of temporomandibular disorder (TMD) and oral parafunctions in
dental assistant students and examine the effects of sex and years of
education. Materials and Methods: One-hundred five dental assistant
students were included in the study. The Fonseca Anamnestic Index (FAI)
was used to evaluate the presence of TMD in individuals, and the Oral
Habit Checklist (OBC) was used to evaluate oral parafunctions. Results:
Sixty-eight individuals (64.8%) had TMD at some level. It was
determined that 46 of the females, who constituted the majority of the
participants, had mild-TMD, which was significantly different from the
males (p<0.001). According to the OBC results, oral
parafunctions were associated with TMD, with low-moderate significant
correlations (p <0.05). Conclusion: Early diagnosis of
temporomandibular joint problems with various questionaries in the
university, especially in the young population, is vital in terms of
disease prognosis and will prevent future complications.

Published: July 2021

Aim: Prostaglandin D2 (PGD2) is implicated in the pathophysiology of
inflammatory diseases. GSK3439171A is a potent, reversible, and highly
selective azetidine urea inhibitor of haematopoietic prostaglandin D
synthase (H-PGDS, a key promoter of PGD2 production in several
inflammatory cell types). Based on favourable preclinical data, we
performed a first-time-in-human study to assess the safety,
tolerability, pharmacokinetics, and pharmacodynamics of GSK3439171A, and
the effect of food on these parameters. Methods: This was a phase 1,
randomized, double-blind, placebo-controlled, dose-escalation study.
Single and repeat oral doses of GSK3439171A were administered to healthy
males aged 18–65 years. Levels of inflammatory markers including
tetranor-prostaglandin D metabolite (tPGDM) were measured in urine
samples. Results: Sixty-six participants were enrolled, with 57
receiving GSK3439171A. Single doses (5–180 mg) and repeat once-daily
doses (5 and 11 mg for 14 days; 40 mg for 7 days) were administered.
Seven participants (12%) had adverse events (AEs) related to study
drug, mainly drug hypersensitivity (n=4 [7%]; non-serious,
transient skin rash). There were no serious AEs (SAEs) or clinically
significant changes in vital signs, electrocardiogram, or laboratory
parameters. Dose-proportional increases in Cmax and AUC(0–inf) were
observed, and the geometric mean half-life of GSK3439171A was up to 12
hours. Results were similar when GSK3439171A was taken with or without
food. No consistent suppression of tPGDM levels was observed.
Conclusion: GSK3439171A was well tolerated in healthy participants and
there were no SAEs. Selective inhibition of H-PGDS offers therapeutic
potential for muscle-related disorders (e.g. Duchenne Muscular
Dystrophy) and muscular recovery following injury.

Published: July 2021

This paper seeks to present surgical procedures, results and complications of treatment of verrucous carcinoma (VC) of the vulva treated at the clinics for gynecology and obstetrics within the Faculty of Medicine, University of Novi Sad (Serbia), as well as a literature review of surgical treatment of VC. During a period of 15 years (2005?2019), we performed 76 surgeries of vulvar cancer, nine (11.8%) due to VC of the vulva. In surgical treatment of vulva VC, we performed complete surgical excision of the tumor (three), complete surgical excision of the tumor with defect coverage using VY fasciocutaneous skin flap (two), simplex vulvectomy (two), radical hemivulvectomy (one), and radical vulvectomy (one). We came across two main complications (22.2%): suture bleeding within 12 hours after excision in one patient (11.1%) and lower extremity lymphoedema after inguinofemoral lymphadenectomy with ligation of the great saphenous vein in one patient (11.1%). Out of the total number of nine treated patients, survival rate was 88.8% (eight patients) with death rate of 11.1% (one patient) within 12 months after surgery. In three patients (33.3%), the disease returned after surgery: one residual tumor after surgery, one relapse on the other side one year after surgery, one newly developed invasive squamous cell carcinoma 10 years after primary surgery.

Anders Nygren’s Agape and Eros, Irenaeus, and the Essence of Christianity
Authors: Kaufman John
Published: July 2021

In Anders Nygren’s seminal study of the Christian concept of love, Eros och Agape, the second century bishop and theologian Irenaeus of Lyons is given an important role in the development of the “Christian idea of love”. In this chapter, I will critically discuss certain aspects of Nygren’s and his colleague Gustaf Aulen’s treatment of Irenaeus. Nygren and Aulen presuppose that one can delineate “pure” concepts or ideas or motifs in history (such as “Christian love”), they maintain that it makes sense to speak of the “essence” of Christianity as a given, and they find their normative basis in the genius of Luther, against which they can evaluate the genuineness of any given conception of Christianity. This is of course both provincial and anachronistic. A critical reading of Nygren’s and Aulen’s understanding of Irenaeus and the concept of Christian love raises important questions concerning objectivity, normativity and givenness. I argue in this chapter that there are no stable given “ideas” or “motifs” that can be “identified” or “discovered” or “described” objectively. I believe it is possible, however, to give accounts that will be recognizable and plausible to others who are familiar with the fragmentary sources upon which our accounts are based. At best, we can together construct plausible understandings of a concept such as Christian love, or of a thinker such as Irenaeus, or of something as broad and multifaceted as Christianity – without purporting to have found the true “essence” of the thing we are studying.
Relations of Love in Texts Read by Early Christians
Authors: Vegge Tor
Published: July 2021

Religious texts talk about love. The present paper comments on a few texts read by early Christians. There are several texts in the Greek translation of the Hebrew Bible (the Septuagint), and in the New Testament, where the specific Jewish-Christian word agapē, translated “love”, occurs. The texts were originally used in contexts where relations between humans followed norms that are not immediately recognizable to us, and words describing relations refer to experiences, emotions and ideas partly foreign to late modern readers. In the Gospel of John love is envisaged in hierarchical relations. God is the supreme. John’s Jesus calls him the Father. Jesus has kept his Father’s commandments, and Jesus passes the commandment to love on to believers, those below him in the hierarchy. In the book of Deuteronomy Jewish and Christian readers could hear that the Lord had “set his heart in love” on their ancestors (Deut 10). The assertion is surrounded by several commandments, expressing what the Lord requires of those involved in the divine love relation. These formulations seem originally to have been couched in the political language of the time. How relevant can these texts be for late modern notions of divine love and human love?

Market of the heavy machinery industry is growing fast. Customers have choices in purchasing new or used equipment or they can decide to rent or leas. Today's brand concept embraces all the things that a product or service offers, including how a product shapes consumers' behavior. The brand's special value is the perception that consumers have to a brand, which is perceived by many factors. This research is based on the Keller model, which includes the main four criteria’s: brand awareness, brand association, perceived quality, and brand loyalty.

The most important reason that customers would changes suppliers is the lack of providing services and products based on customer needs. Through this case study the company, TECHNOCAT, seeks to understand the correlation of the brand and customer re-purchases, whether the value of the brand affects customer decisions in future purchases. The researcher conducted a survey study. The expert panels in the field validated a questionnaire; Cronbach’s alpha coefficient is 0.82 for reliability testing. Managers of the mining businesses and owners of machines are the target population. Statistical Package for Social Science (SPSS) version 23.0 with descriptive statistics and multiple regression were utilized for data analysis, and AMOS was used for the structural equations. The finding presented results from 132 respondents. The study showed that there is a significant relationship between brand equity with an intention to buy again. Furthermore, certain factors; awareness, quality, loyalty, and association with the intention of re-buying, have significantly influence on repurchasing.

The design for manufacturing of granulating machines to produce fertilizer granules in small scale using locally available materials is often challenging and this results in low fertilizer usage among Nigerian farmers when compared with the world’s average usage. A lot of factors are associated with chemical fertilizer granulating machine, and it is necessary to examine and understand the interplay among these factors. This study weighs up a number of variables that relates with the design and usage of chemical fertilizer granulating machine and offers increased insight and awareness about their insidiousness. The study employed a survey approach, using the Rensis Likert’s attitudinal scale, to generate respondents’ data matrix that was analyzed with Principal Component Analysis (PCA), and which was facilitated by statistiXL software. Kendall’s Coefficient of Concordance (KCC) was used to rank the thirty two (32) identified variables and PCA was thereafter deployed to ascertain the degree of interplay among the variables. Results obtained by KCC suggested that judges ranking were consistent as there was sufficient evidence to reject the null hypothesis Also, PCA was indicating parsimony in data reduction from 32 variables to mere five. The result established five principal factors creatively labeled Miscellany Components, Technical Considerations, Granulation Efficiency, Agricultural National policy and Biophysical Elements. The most influential variable by its factor loading of 0.894 is Agricultural National policy. A gamut of variables which seem to affect chemical fertilizer granulating machine has been examined. This has helped in discerning similarities in dissimilarities.

Possibilities for De-carbonizing the Heating and Cooling Sector in the Island of Crete, Greece
Authors: Vourdoubas John
Published: July 2021

Clean energy transition in islands is important and urgent in the current era of climate change. The possibility of de-carbonizing the heating and cooling sector in the island of Crete, Greece has been investigated. Fossil fuels are used in Crete in electricity generation, in heat and cooling production as well as in transportation. The use of various renewable and non-renewable fuels as well as the technologies used in heat and cooling generation has been examined together with the annual changes in fossil fuels consumption during the last years. Various renewable energies like solar energy, biomass and low enthalpy geothermal energy combined with renewable electricity could cover all the heating and cooling requirements in Crete totally eliminating the use of fossil fuels. Their technologies are mature, reliable, and cost efficient.  Renewable and low cost electricity can be easily generated by the abundant solar and wind energy resources in Crete powering electric systems generating heat and cooling. Current work indicates that the heating and cooling sector in Crete can be de-carbonized. This would result in the mitigation of climate change complying with the European goal for carbon neutrality in Europe by 2050.
Can Schrodinger's Cat Be Really a Quantum Touchstone?
Authors: Dumitru Spiridon
Published: July 2021

It is revealed the invalidity of the idea that famous Schrodinger's cat thought experiment can be a quantum touchstone. The arguments are: (i) the probabilistic incorrectness in the (over)rating of the subject, (ii) the possibility of imagining non-quantum scenarios but completely similar to that experiment (iii) lack of ratified practical tests having genuine essence (i.e., non-counterfeit). So, the aforesaid experiment appears as a simplistic thought exercise without any notable significance for quantum physics.
About continuity and discreteness of quantities: examples from physics and metrology
Authors: Pavese Franco
Published: July 2021

The VIM3 defines a quantity as a “property of a phenomenon, body, or substance”, leaving the characteristics of the term ‘quantity’, related to the chosen characteristics of the relevant properties. The question is: does necessarily a property also necessarily refer to the possible granularity of a phenomenon, body, or substance?
Take, for example, for the quantity “mass”: it does not always have to take into account whether or not a phenomenon, body, or substance is subdivided into discrete entities? It depends of the frame of the analysis and also on the chosen measurement unit. In other cases, like temperature, the macroscopic properties are related to the statistical properties of granular substances like atoms and molecules are, so the present meaning of ‘temperature’ is generally lost at the numerical level where the entity’s statistics become meaningless. Yet another case is quantum physics. The paper illustrates the issue and possible solutions under development.

Specification of Distribution for Measurement Results: Bayesian Approach
Authors: Bodnar Olha
Published: July 2021

In the Cochrane Database of Systematic Reviews (CDSR) 75% of reported meta-analyses contain five or fewer studies. For a small dataset a reasonable goodness-of-fit test on a statistical model cannot be performed since either it requires a large sample size for the validity of asymptotic approximation or it might be not powerful enough to detect a deviation from the target model. Random effects model under the assumption of normality is commonly used in many fields of science. It also appears to be a classical approach for data reduction in interlaboratory studies in metrology and in meta-analysis in medicine. However, the assumption of normality might not be fulfilled in many practical applications. If a data set is small, then no statistical test on distribution will perform well. The intrinsic Bayes factor is used for selecting an appropriate probability model among several competitors, which not necessarily have to be nested. We apply the proposed methodology to the measurement results used to determine the Newtonian constant of gravitation and the Planck constant.
The mathematical model of the system-oriented measuring instrument
Authors: Velychko Oleh , Hrabovskyi Oleh
Published: July 2021

Modern measuring instruments (MIs) are designed to obtain complete and reliable measuring information. To perform this important function, MIs must be of appropriate quality and must be reliably assessed. Using mathematical models simulate the operation of technical systems in order to decide on the optimization of its characteristics. As a result of the analysis of the model, the specific features of the studied processes and certain quantitative regularities are established. This allows to predict the processes in the system over time and determine their quantitative characteristics.

The article presents the results of mathematical modeling of system-oriented measuring instruments as a system and its software as a subsystem using the apparatus of general systems theory. Such models with its graphical interpretation allow obtaining the necessary and useful information about the properties of the MIs as a technical system. The performed modeling makes it possible to describe the functioning of the MIs and to obtain a certain assessment of quality indicators.

The paper is devoted to the estimation of the characteristic limits (statistical criteria) for the detection of small amounts of ionizing radiation by a measuring device under conditions of a natural radioactivity background of the environment: the decision threshold, the detection limit, the minimum detectable activity and the confidence interval. The assessment procedures were carried out in accordance with the national harmonized standard DSTU ISO 11929-3:2009.
The threshold for making a decision on the presence of 137Cs and 60Co radionuclides in objects of the external environment and the limit of their detection using a measuring device equipped with plastic scintillators manufactured by the Institute of Scintillation Materials of the National Academy of Sciences of Ukraine were estimated. The influence of the energy of the detected radiation, the dimensions of the scintillators and the geometry of the irradiation on the estimation of the characteristic limits were investigated.
Keywords: scintillator; decision threshold; detection limit; confidence interval; minimum detectable activity.
