Recent advances in robotic design, autonomy and sensor integration create solutions for the exploration of deep-sea environments, transferable to the oceans of icy moons. Marine platforms do not yet have the mission autonomy capacity of their space counterparts (e.g., the state of the art Mars Perseverance rover mission), although different levels of autonomous navigation and mapping, as well as sampling, are an extant capability. In this setting their increasingly biomimicked designs may allow access to complex environmental scenarios, with novel, highly-integrated life-detecting, oceanographic and geochemical sensor packages. Here, we lay an outlook for the upcoming advances in deep-sea robotics through synergies with space technologies within three major research areas: biomimetic structure and propulsion (including power storage and generation), artificial intelligence and cooperative networks, and life-detecting instrument design. New morphological and material designs, with miniaturized and more diffuse sensor packages, will advance robotic sensing systems. Artificial intelligence algorithms controlling navigation and communications will allow the further development of the behavioral biomimicking by cooperating networks. Solutions will have to be tested within infrastructural networks of cabled observatories, neutrino telescopes, and off-shore industry sites with agendas and modalities that are beyond the scope of our work, but could draw inspiration on the proposed examples for the operational combination of fixed and mobile platforms.
Embodied Meter Revisited
Authors: Toiviainen Petri , Carlson Emily
Published: February 2022

Previous research has shown that humans tend to embody musical meter at multiple beat levels during spontaneous dance. This work that been based on identifying typical periodic movement patterns, or eigenmovements, and has relied on time-domain analyses. The current study: 1) presents a novel method of using time-frequency analysis in conjunction with group-level tensor decomposition; 2) compares its results to time-domain analysis, and 3) investigates how the amplitude of eigenmovements depends on musical content and genre. Data comprised three-dimensional motion capture of 72 participants’ spontaneous dance movements to 16 stimuli including eight different genres. Each trial was subjected to a discrete wavelet transform, concatenated into a trial-space-frequency tensor and decomposed using tensor decomposition. Twelve movement primitives, or eigenmovements, were identified, eleven of which were frequency locked with one of four metrical levels. The results suggest that time-frequency decomposition can more efficiently group movement directions together. Furthermore, the employed group-level decomposition allows for a straightforward analysis of interstimulus and interparticipant differences in music-induced movement. Amplitude of eigenmovements was found to depend on the amount of fluctuation in the music in particularly at one- and two-beat levels.

Objective

CR1447, a novel transdermal formulation of 4-hydroxytestosterone, has aromatase-inhibiting and androgen receptor (AR)-modulating properties (IC504.4 nM) with antitumor effects against AR-positive tumor cells in vitro. This trial investigated the efficacy and safety of CR1447 for patients with metastatic estrogen receptor-positive (A) and AR-positive triple-negative breast cancers (B).

Design and methods

(A) included patients with at most one prior endocrine therapy line without progression ≥6 months, whereas (B) included patients with ≤2 prior chemotherapy lines, all displaying advanced signs of disease. The primary endpoint was disease control at week 24 (DC24). The null hypothesis was DC24 ≤30% (A) and ≤15% (B). Thirty-seven patients were recruited (29 in (A) and 8 in (B)); accrual was stopped following an interim analysis demonstrating futility in (A) and slow accrual in (B).

Results

DC24 was attained in 5/21 (95% CI: 8.2–47.2) patients in (A) and none in (B). The median progression-free survival was 5.1 months (95% CI: 2.5–5.6) in (A) and 2.5 months (95% CI: 0.7–2.6) in (B). The median overall survival was 24.6 months (95% CI: 22.9–not applicable) in (A) and 10.8 months (95% CI: 3.3–10.9) in (B). CR1447 had a favorable safety profile without treatment-related grade 3–5 toxicities in (A). Especially no side effects linked to androgenic effects were observed.

Conclusions

Despite this trial being negative, the 24% DC24 rate in a second-line setting, and the prolonged partial response experienced by a patient, indicate activity. Further evaluation of CR1447 in endocrine-sensitive patients or combination trials appears warranted.
Municipalización Educativa: Reflexiones en Base a Tres Experiencias en Latinoamérica
Authors: Pérez Lozada Gisella Azucena
Published: February 2022

El objetivo de este artículo es revisar el proceso de municipalización de la gestión educativa que se gestó durante el periodo 2007 al 2011 en Perú y reflexionar sobre otros modelos en nuestra región. Por lo tanto, revisaremos los modelos peruano, brasilero y chileno considerando que no existe un modelo único. A partir de un enfoque cualitativo que considera una revisión sistemática hemos analizado documentación que incluyó criterios de origen, temática y temporalidad. Los resultados indican que en el caso peruano hubo un apresuramiento en la implementación de la municipalización y como consecuencia hubo duplicidad de funciones; mientras que, Chile ha empezado a desmunicipalizar la gestión educativa, debido a que el enfoque mercantilista socavaba la educación pública. En el caso de Brasil se presenta una educación pública que tiene en todos sus niveles de gobierno una autonomía total, lo que facilita la municipalización de la educación pública sin que eso signifique que no existan complicaciones en la práctica. Podemos concluir que, en nuestra región, la municipalización ha tenido múltiples enfoques, orientaciones y el tema de descentralizar la educación tienen muchas aristas por explorar.

Published: February 2022

El estudio de las consecuencias sanitarias en el sector educación es significativo. En ese sentido, el propósito del trabajo de investigación es determinar la correlación de la confianza en sí mismo y el sentirse bien solo, como resiliencia y el estrés académico en alumnos de quinto grado de educación secundaria en aulas piloto de un colegio público en el contexto del COVID-19. Este trabajo se realizó con un enfoque cuantitativo, de tipo básico y metodología descriptiva, correlacional, donde se encuestaron virtualmente a 52 estudiantes escogidos por “criterio-juicio” (Tamayo, 2001), usando el Rango de resiliencia (Wagnild y Youbg, 1993) y la adecuación del cuestionario de estrés académico SISCO SV al entorno del COVID-19 (Alania et al., 2020). Existe relación significativa negativa media para la confianza en sí mismo y en forma considerable para sentirse bien solo, con el estrés (r=-.656 y r=-.717) respectivamente (p<0.01), concordante con otros estudios. Sosteniendo que estudiantes de aulas piloto que cuentan con apoyo material y familiar tienen mayores capacidades de resiliencia desde su “confianza en sí mismo” y el “sentirse bien solo”. Por lo tanto, sufren menor estrés académico en el contexto de la educación virtual por el COVID-19, por lo cual el trabajo debe estar dirigido a empoderar las capacidades de resiliencia desde la familia y el colegio.
Influence of Point Defects on the Equilibrium Concentration of Interstitial Oxygen in Crystalline Silicon
Authors: Sarikov A.
Published: February 2022

The effect of excess point defects on the equilibrium concentration of interstitial oxygen for the system of interstitial oxygen/SiO2 precipitates in crystalline Si is theoretically investigated. The expression for the equilibrium concentration of interstitial oxygen in Si modified by the excess point defects is derived. Excess vacancies in Si are found to decrease this concentration, while the excess Si self-interstitials have the opposite effect. The effects of different conditions for the point defect generation on the equilibrium in the system of interstitial oxygen/SiO2 precipitates in crystalline Si are studied.
Superions in the Narrow Nanopores with Multiple Occupancy
Authors: Kharkyanen V.N. , Yesylevskyy S.O. , Berezetskaya N.M.
Published: February 2022

The general theory of the single-file multiparticle diffusion in narrow pores can be greatly simplified in the case of the inverted bell-like shape of a single-particle energy profile, which is often observed in biological ion channels. There is a narrow and deep groove in the energy landscape of multiple interacting ions in such profiles, which corresponds to the pre-defined optimal conduction pathway in the configurational space. If such a groove exists, the motion of multiple ions can be reduced to the motion of a single quasiparticle, called the superion, which moves in a one-dimensional effective potential. The concept of superions reduces the computational complexity of the problem and provides the very clear physical interpretation of conduction phenomena in narrow pores.
Uncertainties Due to Hadronic Production in Final-State Interactions at Long-Baseline Neutrino Facility
Authors: Devi R. , Singh J. , Potukuchi B.
Published: February 2022

Recent neutrino oscillation experiments used high atomic number nuclear targets to attain sufficient interaction rates. The use of these complex targets introduced systematic uncertainties due to the nuclear effects in the experimental observables and need to be measured properly to pin down the discovery. Through this simulation work, we are trying to quantify the nuclear effects in the argon (Ar) target in comparison to hydrogen (H) target which are proposed to be used at Deep Underground Neutrino Experiment far detector and near detector, respectively. Generated Events for Neutrino Interaction Experiments and NuWro, two neutrino event generators, are used to construct final state kinematics. To quantify the systematic uncertainties in the observables, we present the ratio of the oscillation probabilities (P(Ar)/P(H)) as a function of the reconstructed neutrino energy.

EFL Teachers’ Classroom Management Orientation, Self-Efficacy, Burnout, and Students’ L2 Achievement
Authors: Mahmoodi Mohammad Hadi , Hosseiniyar Shiva , Samoudi Negin
Published: February 2022

This correlational study examined the relationship among some English teachers’ characteristics and their students’ foreign language learning. Eighty-two Iranian high school teachers who taught English completed a battery of questionnaires. The scores of the teachers’ students on their final exam were collected as indicators of their English achievement. The results revealed that there was a positive relationship between the teachers’ self-efficacy, classroom management orientations, personal accomplishments (a subscale of burnout), and students’ L2 performance. However, the correlations between emotional exhaustion and depersonalization (two subcomponents of burnout) and students’ English learning were negative. Furthermore, the findings indicated that the teachers’ self-efficacy was the strongest predictor of learners’ English learning. These findings highlight the importance of such teachers’ characteristics for their learners’ L2 learning.

Published: February 2022

This paper reports a collaborative autoethnography on a first teaching practicum at Universidad Surcolombiana. The study aimed at how we, as novice researchers and preservice English as a foreign language teachers, make sense of our teaching experiences in our first teaching practicum using collaborative autoethnography as a research method. The data were collected by reflective journals and ethnographic observations. Results show the meaning that we give to our experiences, before and during the COVID-19 pandemic, by recognizing and analyzing our sociocultural context. Additionally, we were immersed in a virtual learning environment where we had the opportunity to confront unforeseen changes imposed by the pandemic, familiarize ourselves with possible issues that teachers grapple with, and imagine new ways to be ourselves.
Compiling a Corpus of Audiovisual Materials for EFL Learning: Selection, Analysis, and Exploitation
Authors: Wood-Borque Paula
Published: February 2022

Films and series are usually consumed in leisure moments, but they can be included in the English as a foreign language classroom as they offer real-life language in context, which can help develop learners’ communicative competence. This paper examines how audiovisual materials can promote English acquisition in secondary education and proposes a corpus of films and series for this purpose. Two surveys will be presented, one for compiling fragments, and the other regarding students’ viewing habits. The fragment selection process will be explained, and some illustrations of the fragments’ exploitation will be described. This medium’s language learning benefits will be discussed, and it will be argued that using this corpus can have a positive influence on students’ communicative competence development.

Published: February 2022

This qualitative research study delves into elementary school teachers’ beliefs and the potential contribution of reverse mentoring to improve English language teaching for children. The purpose was to explore how elementary in-service teachers’ beliefs could be transformed after participating in a reverse mentoring experience. A group of in-service teachers from two public elementary schools and a group of student-teachers from Universidad de Córdoba (Colombia) were the research participants. Data were gathered through a questionnaire, interviews, and classroom observations. Findings showed that reverse mentoring played an important role in transforming in-service teachers’ beliefs about teaching English to children regarding the difficulties of language learning, communicative strategies, motivation and expectations, foreign language aptitude, and the nature of language learning.
English Language Preservice Teachers’ Identity Construction Within Academic and Other Communities
Authors: Posada-Ortiz Julia
Published: February 2022

This article reports on a doctoral research that sought to unveil the identities present in the communities to which four English as a foreign language preservice teachers belong. The study was carried out with a decolonial perspective that included an interepistemic dialogue among narrative inquiry, narrative pedagogy, and the indigenous research paradigm. The main instrument of data collection was autobiographies. The participants and the researcher analysed data jointly. The findings indicate that the preservice teachers’ identity construction is mutable and not essentialised. Mutable as it changes over time and not essentialised since it involves social, cultural, and personal dimensions.

A metodologia de análise proposta desenvolve-se no quadro teórico formulado por Bakhtin e o Círculo para articular a verticalidade à horizontalidade e buscar, no cruzamento dessas direções, profundidade e abrangência; singularidades e a generalização possível e desejável em uma pesquisa. Para apresentar essa metodologia, o artigo se apoia em um recorte de uma pesquisa de doutorado que ouviu jovens concluintes do ensino médio para saber seus valores, planos de futuro e como avaliavam a escola.
Los primeros cien años del legado dialogista
Authors: Orlando Virginia
Published: February 2022

Los últimos veinte años de trabajo de la comunidad académica internacional sobre los escritos “bajtinianos” han arrojado atractivos resultados, agrupables en los tres asuntos siguientes: ajustes en las traducciones, revisión -no exenta de polémica- de las asignaciones de autoría al pretendido Círculo de Bajtín, y también interpretaciones enriquecidas acerca de la contribución del marco conceptual que presentaré aquí como dialogismo. En este trabajo me propongo recuperar algunas de las principales líneas de discusión desarrolladas acerca de las elaboraciones conceptuales de Bajtín, Medvedev y Volóshinov (BRANDIST, 2006, 2012), asumidos aquí en su conjunto como constructores del dialogismo por las razones que más adelante serán expuestas. Defiendo la necesidad de preservar las orientaciones dialogistas, presentes en el análisis del discurso y la lingüística aplicada, en nuestra contemporaneidad.
Desigualdade social vista do alto do morro
Authors: Ramalhete Mariana Passos , Moreira Tatiana Aparecida
Published: February 2022

Este trabalho analisa, à luz da perspectiva enunciativo-discursiva da linguagem do Círculo de Bakhtin, o rap Canção Infantil, de autoria do capixaba César MC. Parte da premissa que, em uma sociedade desigual, o signo é mais que um emaranhado de palavras: é arena onde se desenvolve a luta de classes. Desse modo, por meio de uma abordagem qualitativa de procedimento documental, discute como esse rap, calcado na alusão simultânea ao simbólico e ao real, dá visibilidade às consequências da desigualdade social, ao abordar parte dos problemas inerentes à periferia.  Conclui que o rap, além de expor as chagas e as contradições da sociedade brasileira, em um posicionamento cíclico e dual, afasta-se de uma perspectiva marginalizada e/ou glamourizada da pobreza, a partir de lentes menos superficiais e, por isso, menos maniqueístas.
As noções bakhtinianas de linguagem e enunciado
Authors: Paula Luciane de , Luciano José Antonio Rodrigues
Published: February 2022

Neste artigo, a proposta é refletir a respeito da relação enunciado e linguagem presente no pensamento filosófico do Círculo de Bakhtin. Os objetivos são: a) compreender como o grupo de filósofos russos elabora e delimita sua concepção de linguagem e enunciado; e b) conceber uma ontologia capaz de refletir acerca da existência humana. O método dialético-dialógico desenvolvido pelo Círculo pauta a discussão. O estudo leva aos resultados de que a construção conceitual de linguagem é realizada dialogicamente, na fronteira das disciplinas, sobretudo das Ciências Humanas (mas não apenas) – como música, literatura, linguística, artes plásticas, biologia, psicologia, sociologia, entre outras. Estas, por sua vez, são unificadas em torno do problema da linguagem, materializada no ato enunciativo, como modo de efetivação do homem, em seu  acabamento ético e estético no mundo. A relevância desta reflexão se volta à pertinência da filosofia da linguagem bakhtiniana como aporte para análises de enunciados visuais, vocais/sonoros e/ou sincréticos, além de e com a materialidade verbal, sobre a qual os pensadores do Círculo se centraram de maneira privilegiada.

And Then the Buddha Smiled
Authors: Appleton Naomi
Published: February 2022

Part A of the volume introduces the Avadānaśataka and its themes and concerns, with a particular focus on placing the first four chapters of the text – those translated in Part B of the volume – into the context of developing ideas about the Buddha and buddhahood. After a general introduction to the text, the discussion moves through themes that are core to each of the chapters under discussion: the many buddhas of the past and future who feature in chapters 1 and 2; the past lives of the most recent Buddha, Śākyamuni, which are related in chapters 2 and 4; and the pratyekabuddhas (beings awakened in times of no Buddhism) of chapter 3. The discussion then uses features common to the whole text, including miracles, aspirations and predictions, to mount an argument that the Avadānaśataka treads a fine line between acknowledging the validity of the three paths to awakening (full buddhahood, pratyekabuddhahood and arhatship) while clearly placing full buddhahood at the pinnacle. Furthermore, even within the category of full buddhas, Śākyamuni Buddha takes centre stage as the miracle-working, prediction-making, magical-smiling, utterly awe-inspiring Buddha of our time.

Third Decade (Stories 21-30)
Authors: Appleton Naomi
Published: February 2022

The third chapter is about pratyekabuddhahood, or the awakening of ‘solitary’ or ‘independent’ buddhas, who achieve awakening in times of no Buddhism. Eight of these ten stories concern people predicted by Śākyamuni Buddha to achieve pratyekabuddhahood in future lifetimes, and these echo the stories of the first decade. The two remaining stories are told by Śākyamuni to explain the crumbling stūpas (reliquaries) of past pratyekabuddhas that he and his disciples encounter.
Improving the adaptive filtration of the foam surface glare trend
Authors:   Perm National Research Poly- technic University, Berezniki branch, Fedoseeva Kristina
Published: February 2022

One of the important processes in the production of potash fertilizers is the froth flotation process. The quality of the final product depends significantly on the quality of the flotation. Technical vision is successfully used to control the flotation process. However, the existing methods of processing the video stream are inapplicable for controlling the process of flotation of potash ore due to the large scatter of statistical characteristics from one processed frame to another. This article discusses the use of nonblind filters to process streaming data. It is concluded that their application causes problems in identifying the moment of the beginning of the deviation. Based on this, the aim of the work is to reduce the noise level without affecting the identification of the transient, in other words, to improve the identification of the beginning of the transient by means of tunable blind filtering. It is proposed to recognize sets of N consecutive frames instead of single ones. For this, for each N frame, the number of bubbles, the average and median distances between them, and the average values of illumination and color components were calculated. From these calculations, it was concluded that the use of the arithmetic mean number of flares from N frames did not lead to an effective, significant reduction in the noise level. Therefore, it was proposed to use a different vector norm. As a result, an effective method for adaptive filtering of the trend of the number of highlights has been developed. On the materials of real video filming, a study was made of the change in noise from the number of frames. The results obtained show that the proposed method can reduce the standard deviation by 10-25% for different surveys. This proves the possibility of using the developed method for processing video streams both in laboratory and in industrial conditions.

This paper examines the main generally accepted market concentration indices adapted to the sub-industry structure. These indicators can be metrics for determining the dominant sub-sectors, which can be used to analyze cluster interactions. In fact, indicators can serve as an indicator of the potential for the development of cluster interaction. The current study hypothesizes that if there is one dominant sub-sector in the region, then enterprises that are "representatives" of such a sub-sector, having the most significant weight in the formation of this sub-sector and the industry as a whole, will influence the change in the GRP of the region much more than other enterprises not from the dominant industry. Thus, the paper exploresthe relationship between these metrics and the rate of gross regional product per capita, as one of the key indicators of regional development. At the first stage, a neural network is built and trained to identify a pattern between one of the metrics and the rate of gross regional product. Further, approximating by n-th order polynomials, various specifications of regression equations are considered, between all metrics and the change in the rate of gross regional product. The assumption is made that only the diversification of production does not lead to the socio-economic development of the region, but the creation and development of cluster interaction allows to increase the rate of gross regional product.

OPTIMIZATION OF ULTRASOUND-ASSISTED EXTRACTION OF OLIVE LEAF (var. HALHALI) EXTRACTS
Authors: ÜNVER Naciye , ÇELİK Şerafettin
Published: February 2022

In this study, the effects of
three different independent variables (extraction temperature, extraction time,
ultrasonic power) on the total phenolic content, extraction yield and
antioxidant capacity (IC50) value of olive leaf extracts of Halhalı
variety which is originated from South-eastern Anatolia Region were
investigated. As a result of the evaluation made with Box-Behnken Design Model,
the optimum conditions were determined as 62.94°C, 50.67 min, and 64.65%
ultrasonic power for the optimization of ultrasonic-assisted extraction. In order to visualize the effect of
extraction method on TPC, extraction yield and IC50 value of olive
leaf extracts, results of three extraction methods were compared. The
differences among the mean values of the investigated parameters in terms of
extraction method were found significantly different (P<0.05). In addition, it can be inferenced that
ultrasound assisted extraction accelerated the transition of phenolic
substances to solvent in terms of SEM images and investigated other parameters.
Ischemic heart disease: medical certificate of cause of death analysis
Authors: Samorodskaya I. V. , Chernyavskaya T. K. , Kakorina E. P. , Semyonov V. Yu.
Published: February 2022

Aim. According to data from the Moscow Oblast civil registry office in 2020, to analyze medical certificates of cause of death (MCCD), where the code from “Ischemic heart disease” (IHD) (I20-I25) group is indicated as underlying cause of death (UCD).

Material and methods. A total of 23193 deaths with I20-I25 codes (UCDs) were included. We assessed the prevalence of individual IHD types, the frequency and patterns of complications, the average age of deceased persons, the proportion of women and men, place of death registration.

Results. The average age of the deceased was 73,6±12,5 (men, 68,8±10,5; women, 78,4±12,5; p<0,0001). The proportion of women who died under the age of 70 was <20%, men — >50%. Half of the deaths were registered at home, a third in a hospital, and the rest elsewhere. Taking into account age and sex, inhospital death from myocardial infarction (MI) is recorded 12 times more often than in “other forms of acute IHD”. Chronic forms of IHD were registered in 76,9% of cases; in 47,3%, such IHD form as “Atherosclerotic heart disease” was noted. The proportion of deaths from acute MI and deaths after MI was 37,3%. In 92,1% of MCCDs of “other forms of acute IHD”, “acute coronary insufficiency” is indicated. Differences in the prevalence of various IHD forms between men and women were significant (p<0,0001). In female mortality pattern, there are 3 times less deaths from other (non-MI) acute forms of IHD and almost 2 times less deaths from old myocardial infarction and cardiac aneurysm. As the immediate cause of death, heart failure was indicated in 78,9%, while among those with prior MI — in 91%. In other acute forms of IHD, acute coronary insufficiency was indicated in 89%.

Conclusion. A high proportion of deaths with unspecified acute and chronic forms of IHD as the cause of death, especially in young men, requires a comprehensive study and development by the Russian Society of Cardiology of criteria for death from various IHD forms.

Aim. To assess the impact of calcific aortic stenosis on long-term prognosis in patients with stable coronary artery disease (CAD) included in the PROGNOZ IBS registry.

Material and methods. The analysis included data of patients (n=541; men, 432; women, 109) from the CHD PROGNOSIS registry, in whom diagnosis of CAD was confirmed using coronary angiography during reference hospitalization in the National Medical Research Center for the period from January 1, to December 31, 2007. The mean age of men was 57,5±0,4, women — 60,9±0,9 years. The survival analysis included 504 patients (93%). The mean follow-up period was 7,3±2,19 years. We assessed the presence of calcific aortic stenosis (CAS) according to echocardiography and data on endpoints after 4 and 7 years of follow-up.

Results. CAS according to echocardiography during reference hospitalization was found in 29 patients (5,4%) with a confirmed CAD. After four-year followup, 7 patients (24,1%) died, after 7 years — 15 (51,7%). Fatal and non-fatal cardiovascular events (primary endpoint) after 4 years were revealed in 10 patients (34,5%), and after 7 years, all cardiovascular events were fatal (n=15; 51,7%). In the presence of aortic stenosis, the relative risk (RR) of all-cause death at 4-year follow-up increased by 2,9 times (p<0,01), while at 7-year follow-up — by 3,2 (p<0,0001). The RR for the primary endpoint at 4-year follow-up increased by 2,8 times (p<0,01), while at 7-year follow-up — by 2,3 times (p<0,001). The RR of death in CAS patients at 7-year follow-up was comparable to severe heart failure — 3,3 (p<0,01), stroke — 2,4 (p<0,05) and left main coronary artery stenosis — 2,5 (p<0,0001).

Conclusion. The presence of calcific aortic stenosis had a pronounced negative effect on the long-term prognosis of CAD patients, comparable with those in left main coronary artery stenosis, severe heart failure and stroke.

Aim. To determine the effectiveness of thromboelastometry (TEM) and echocardiography for anticoagulant therapy monitoring in patients with COVID-19.

Material and methods. We analyzed treatment regimen of 92 patients with COVID-19. The patients were divided into two groups. In the control group (n=30), anticoagulant therapy with unfractionated heparin (UFH) was carried out under laboratory control of coagulation parameters. In the experimental group (n=62), anticoagulation was maintained by intravenous UFH under control of coagulation, echocardiography (Philips, Epiq 5) and TEM (ROTEM® delta). Echocardiography determined the pulmonary artery acceleration time (AT), mid-systolic notching (SN). The TEM method was used to study external (EXTEM) and internal (INTEM) pathways, differential tests (FIBTEM, HEPTEM) of coagulation. Statistical analysis was performed by calculating non-parametric statistics parameters, comparisons of differences in groups (Mann-Whitney test), area under the curve (AUC), and regression equations.

Results. A high correlation level between echocardiographic and TEM parameters was determined. Their levels associated with a positive prognosis were calculated (AT>113,5 ms., AUC 0,979; p<0,0001; no SN, AUC 0,931; p<0,0001; FIBTEM ML (60 min) >1,12%, AUC 0,971, p<0,0001; INTEM ML (60 min) >2,01%, AUC 0,941, p<0,0001, EXTEM ML (60 min) >1,4%, AUC 0,934, p<0,0001; MCFfib not >26 mm, AUC 0,954; p<0,0001; MCFin not >56,6 mm, AUC 0,938; p<0,0001; MCFex not >47,9 mm, AUC 0,838, p<0,0001). In 33,9% of patients in the experimental group, heparin resistance was detected. In this connection, combined therapy with UFH and direct oral anticoagulants (DOACs) was used, followed by the switch to DOACs. In the control group, artificial ventilation was used in 50% of patients, mortality — 36,6%, myocardial infarction — 13,3%, deep vein thrombosis — 6,6%, pulmonary embolism — 6,6%, while in the experimental group, mechanical ventilation — 12,9%, myocardial infarction — 4,8%, mortality — 8,1%.

Conclusion. The dynamic assessment of echocardiography and TEM parameters made it possible to monitor pulmonary thrombosis processes, significantly reduce complications, the use of artificial ventilation and mortality in COVID-19 patients.

Background: Stroke is a neurological condition caused by an immediate injury to the CNS due to vascular sources like cerebral infarction, intracerebral haemorrhage, or subarachnoid haemorrhage. Stroke leads to changes in cognitive and psychological functioning, body disabilities and profound fatigue. After a stroke, patients are likely to produce an asymmetric gait pattern, decreased gait speed and decreased cadence. This leads to restricted independence and participation in the community and social activities. The aim of the study is to analyse the correlation between walking ability and measures of social participation. Methodology: Forty subjects were screened for inclusion criteria. They were explained about the procedure and gained informed consent for all the tests of walking ability and questionnaires were given for analysing their participation in social life activities. Walking ability was analysed by using 6-minute walk test, 10-meter walk test, Fall Efficacy Scale (FES), and Functional Ambulation Category (FAC). Social participation was analysed by using 3 questionnaires -POPS, IPAQ, and PARTS/M. Spearman correlation analysis was done to analyse the relationship between walking ability and domains and dimensions of social participation. Results: The correlation analyses revealed that the walking ability measured by 6-minute walk test, 10-meter walk test, FES and FAC scores correlate with the domains and dimensions of social participation by using the questionnaires-POPS, PARTS/M and IPAQ. Measures of walking ability i.e., 6-minute walk test were correlated with satisfaction (r=0.312; p<0.05); FES with satisfaction (r=-0.396; p<0.05); FAC with satisfaction (r=0.436; p<0.05) dimensions of social participation. Measures of walking ability i.e., 10-meter walk test were correlated with major life area domain (r =-0.407; p<0.5); FES and general tasks and demands (r=-0.334; p<0.05); FAC and general tasks and demand domain (r=0.327; p<0.05). Conclusion: Walking ability was significantly correlated with measures of domains and dimensions of social participation. KEYWORDS: Stroke, POPS, PARTS/M, CVA, Social Participation, Walking Ability.

Introducción: Las tecnologías de la información y la comunicación combinadas con simulación clínica optimizan los procesos de enseñanza - aprendizaje en la formación del recurso humano en salud. Métodos: estudio cuasiexperimental en 91 participantes asignados en tres grupos. El G1 recibió la intervención 1, el G2 recibió la intervención 2 y el grupo control recibió la intervención tradicional. El conocimiento teórico-conceptual se midió con una prueba de conocimiento y la habilidad procedimental con una lista de chequeo. Resultados: el aprendizaje teórico-conceptual y la habilidad procedimental mostró diferencias significativas entre los grupos (p=0.01), con mayores puntajes en los grupos de intervención frente al GC que; aunque se presentó un ligero incremento en los puntajes, este no superó los G1 y G2. Conclusiones: La enseñanza aprendizaje con el uso del RED “inserción del catéter venoso periférico” es eficaz, porque incrementa el aprendizaje teórico, conceptual y de habilidad procedimental en estudiantes de enfermería y es significativamente mejor cuando este se acompaña de un docente adherido al contenido del recurso. El RED en simulación favorece el aprendizaje autónomo, y se constituye en una herramienta útil, en la formación de pregrado, y en programas de educación continua.

Mithilfe eines Kunstkopfmesssystems wurden die real messbaren Dämmwerte von fünf aktuell erwerbbaren Kapselgehörschützern für Kinder in einem schallarmen Laborraum ermittelt. Die vom Hersteller auf der Produktverpackung angegebenen Dämmwerte lassen Eltern vermuten, dass die Kinder bei Verwendung eines Kapselgehörschützers ausreichend vor Lärm geschützt sind. Vor allem in den tiefen und hohen Frequenzbereichen wurden aber zum Teil erhebliche Abweichungen zwischen den angegebenen und gemessenen Dämmwerten nachgewiesen.

Study of the implementation and acceptance of the SARS-CoV-2 occupational safety and health standard and the SARS-CoV-2 occupational safety and health rules for successful infection control in companies Objectives: This study is intended to provide insights into the real-life implementation of SARS-CoV-2-related occupational safety and health (OSH) measures in German companies. It should also help to identify possible perspectives for further measures to improve the approach of the German accident insurance institutions in comparable situations and to reduce the burden on employees. Methods: Between December 2020 and May 2021, we conducted an online survey on the implementation of SARS-CoV-2 OSH measures. With the help of various German Social Accident Insurance Institutions, we recruited 344 OSH professionals and 92 other people with OSH responsibility from the public sector, industrial, financial, retail and local public transport sectors, and analysed their responses. Results: Most OSH professionals are familiar with SARS-CoV-2 OSH standards, SARS-CoV-2 OSH rules and sector-specific supplements. In only very rare exceptions (1 %) were the employees not informed of preventive and occupational safety measures that had been initiated. Sector-specific differences were particularly evident in contact reduction measures and the stockholding of protective equipment. The increase in mobile working and the greater use of digital communication media were cited as major longterm consequences of the pandemic on future work types. Conclusions: This study confirms that the importance of occupational and infection protection has increased in the SARS-CoV-2 pandemic. Many companies took infection control measures early in the pandemic. Keywords: coronavirus – COVID-19 – SARS-CoV-2 pandemic – preventive measures – occupational safety and health professionals
