Authors: Machado Alba Jorge
Published: February 2022

Background:Asthma affects approximately 358 million people worldwide. Objective:To determine the trend in the use of medications used to treat asthma in a group of patients affiliated to the Colombian health system. Methods:A retrospective study on prescription patterns of medications used to treat asthma in patients over 5 years of age between 2017 and 2019. Sociodemographic variables, medications used and combinations, persistence of use and prescribing physician were considered. Data were obtained from a drug-dispensing database from Colombia. Results:10,706 people with a diagnosis of asthma were identified, with predominance in female sex (56.8 %), mean age 32.2 ± 26.1 years. At the start of follow-up, 53.2% of patients aged 5-11 years were receiving monotherapy, mean 1.5 ± 0.6 drugs/patient, especially inhaled corticosteroids (ICS; 55.9%) and short-acting β-agonists (SABA; 55.6%). Moreover, in patients older than 12 years, 53.5% were treated in monotherapy, mean 1.6 ± 0.7 drugs/patient, of which 45.9% were on SABA, and 37.1 % on ICS.Between 63.0% and 83.6% of patients were treated by a general practitioner. The proportion of patients on the ICS/ long-acting β-agonists (LABA) combination grew at 24 months follow-up by 411% and 177%, respectively. 12.5% of patients (n=495) received triple therapy (ICS/LABA+LAMA [long-acting anticholinergics]), particularly with fluticasone/salmeterol + tiotropium. Conclusions:Patients with a diagnosis of asthma older than 5 years in Colombia are mainly receiving control therapy with ICS, alone or combined with SAMA and, to a lesser extent, with LABA.

Corpus-driven genre pedagogy of English for research publication purposes: Toward an ELF-referenced critical teaching framework
Authors: Lubis Arif Husein
Published: February 2022

Ever since the NNES and novice writers became actively engaged with international publications, the pedagogy of English for research publication purposes (ERPP) has received considerable attention from the EAP/ESP scholars using corpus-driven genre pedagogy. However, the quality of its implementation is still understudied. This study, therefore, critically reviews the qualitative milestone of corpus-driven genre pedagogy of ERPP. Nineteen (19) relevant research-based articles about corpus-driven genre pedagogy in the last 15 years from 2004 to 2019 were selected from Google Scholar and three top-tier journals in this realm: Journal of Second Language Writing, English for Specific Purposes, and Journal of English for Academic Purposes. Three stages were conducted, i.e. preparation, screening and validation, and content review. The findings encompassed: 1) the materials development process, 2) the learners’ engagement, and 3) the development of learners’ research writing competencies and clinical soft skills. The findings become the bases for proposing a framework of ELF-referenced critical corpus-driven genre pedagogy of ERPP.
The Impacts of Liberal Arts Education of Jesuit School Culture on English Teachers’ Transformed Agencies
Authors: Sutono Aditya Agung , Budiraharjo Markus
Published: February 2022

Teachers as agents of change play a key role to not only assist their students with their learning, but also to professionally navigate the tension among their own beliefs, school culture, and the mandated curriculum. Drawing upon principles of Liberal Arts Education, a Jesuit Senior High School in Yogyakarta has carried out liberal arts education (LAE) since its inception in 1948, so as to nurture students’ capability to make their own choices and become responsible to their own deeds. This study is set to 1) discover transformative processes of four English teachers in their efforts to adopt and adapt to existing school values, and 2) elaborate the ways in which these teachers adopted and implemented the LAE and Ignatian Pedagogy into their teaching activities. This research employs Narrative Inquiry for its research method. Data gathering was accomplished by interviews, school observations, field notes, and document analysis. Four English teachers and some students were involved in the interviews. To guide data analysis, Mezirow’s (1998) Critical Self-Reflection of Assumptions (CSRA) and Biesta, Priestly, Robinson’s (2015) teacher agency were utilized. Findings suggest that transformed agencies took place in response to catalytic moments, especially due to the changing nature of students and the expectation to maintain quality teaching. Further studies may address a larger scope of teacher agencies among teachers in public schools.

Authors: Ole Faith Celeste
Published: February 2022

This study aimed to develop and validate an instrument regarding teachers’ practices on formative assessment using the elements of the Feedback Loop Model. A pilot study was surveyed to 157 science teachers on how frequently they practice formative assessments in their Science classes. Teachers’ responses were analyzed using Cronbach’s alpha statistics on the Feedback Loop constructs and Confirmatory factor analysis for the entire instrument. Findings suggest that with the deletion of 10 survey items from the initial 44 items, the scale provides a valid and highly reliable measure in determining teachers’ practices on formative assessment.
The Use of First Language (L1) in EFL Classrooms: Teachers’ Practices and Perspectives
Authors: Sundari Hanna , Febriyanti Rina Husnaini
Published: February 2022

Teaching English in the context of foreign language needs vigorous efforts and strong commitment, especially for non-native English-speaking teachers to maintain professionalism and to achieve the success of learning language. Generally, it is believed that a teacher should be a language model for the learners by providing a great deal of input in the target language and applying the L2 only policy. However, some teachers finally decide to use their first language (L1) or mix it with the target language (L2) while teaching. This qualitative study investigated the frequencies, functions, and teachers’ perceptions of their L1 use in EFL classes. Twenty English teachers from lower secondary schools in Jakarta, Indonesia were asked to participate. The data were collected through classroom observations, in-depth interviews, and focus group discussions. The finding obtained that the frequency of the L1 was seemingly noticeable but not overused. Moreover, teachers used first language mostly for activity objective, translation, comprehension check, and activity instruction. The finding also revealed that the majority of the teachers decided to mix first language and target language with different proportions. Meanwhile, the others decided to use a small portion of target language. Only few teachers consistently tried to instruct mostly in target language. The finding implies the need for teachers to reduce the usage of first language (L1) during the teaching process to get maximal result.

Authors: Bautista-Flores Alexandra , Alvarado Mayor Paola Natalia , Lovera Arellano Amanda Asunción
Published: February 2022

Background: Therapeutic advances against cancer have not been as successful as expected and have adverse effects that patients rarely tolerate. A study in Peru identified favorable anticancer effects of Annona muricata (AM), a medicinal plant known as soursop, in C-678 mouse gastric adenocarcinoma. However, to date, no results have been reported in human cells. Objective: The objective of this study was to determine the cytotoxic effect of AM extract against a human gastric adenocarcinoma cell line (AGS). Methodology: Experimental in vitro analytical study using a hydroalcoholic extract of AM (AMOH) leaves collected in the Amazonas. Chemical functional groups were identified by phytochemical screening. To obtain the cytotoxic effect, different dilutions of extract were added to the plates containing the cell lines and the data were extrapolated to GraphPad employing an observation card. Finally, the cytotoxic effect was expressed as the half-maximal inhibitory concentration (IC50) and nonlinear regression analysis was performed to determine the growth inhibition of cancer cells. Results: Phytochemical screening showed the presence of reducing carbohydrates, alkaloids, phenols, tannins, triterpenes, steroids, saponins, flavonoids, proteins, cardiac glycosides, and anthocyanins. A calibration curve with gallic acid was used to determine the total phenol content and, quercetin was used to identify the flavonoid content. The AGS cell line showed cytotoxic activity with AMOH with an IC50 at 24 hours of 45.81 µg/mL and 19.05 µg/mL at 48 hours. Conclusion: Several chemical functional groups of AM were identified. In addition, the AMOH showed a cytotoxic effect against the AGS cell line.
Welfare Deservingness for Migrants: Does the Welfare State Model Matter?
Authors: Saar Maarja , Sojka Bozena , Runfors Ann
Published: February 2022

This article draws on the idea that welfare systems and institutions are based on normative assumptions about justice, solidarity, and responsibility. Even though the literature on welfare deservingness has highlighted the connection between ideas of solidarity and the support to, for instance, people with different ethnic backgrounds, there is very little research on the interconnections of different welfare state models and ideas on how migration should be governed. This article suggests that there is a link between the welfare state models suggested by Esping‐Anderssen and different discourses on migrant welfare deservingness. The article explores the interlinkages of three welfare state models—liberal, socialdemocratic, and continental‐corporative—and four discourses on welfare deservingness of migrants in respect to social welfare—labourist, ethno‐cultural, residential, and welfarist (see Carmel & Sojka, 2020). It is suggested that the normative foundations embedded in different welfare systems lead to dissimilar ways of approaching migrants and migration.

O Cerrado é conhecido por possuir clima estacional, com duas estações bem marcadas - chuvosa e seca, e abriga em seu território nascentes das três maiores bacias hidrográficas da América do Sul.   Deste modo, o objetivo desse trabalho foi realizar o biomonitoramento do córrego Cabeça de Veado por meio dos í­ndices biológicos Biological Monitoring Working Party (BMWP) e Average Score per Taxon (ASPT), aplicados aos dados da entomofauna. Com este propósito foram realizados, no intervalo de um ano, dois perí­odos de coletas em cinco pontos do curso dââ?¬â?¢água. Foram realizadas análises fí­sicas e quí­micas e granulométricas sobre a água e sedimentos. Os espécimes coletados foram identificados a ní­vel de famí­lia. Para todos os pontos amostrados, os resultados das análises indicam qualidade ââ?¬Ë?Duvidosaââ?¬â?¢ ou em categorias inferiores, sendo esses valores explicados pela ausência de ordens caracterí­sticas de ambientes conservados. Assim, fica evidente a necessidade de acompanhamento da qualidade do curso d'água, para que ações de manejo, manutenção e recuperação sejam implementadas no córrego.
NOMINATIVE FIELD OF THE CONCEPT JOY IN PLAUTUS’ COMEDIES
Authors:   Danylo Halytskyy National Medical University of Lviv, Chernyukh Nadiya
Published: February 2022

The article considers the means of nomination of the emotional concept JOY and their place in the formation of the eponymous concept sphere in Plautus’ comedies. The means of direct nomination of this concept are formed from the base gaud- noun gaudium and the verb gaudere, which are dominant (63 %), derivatives from the base laet-: noun laetitia, the adjective laetus and the verbs laetari and laetifico (25 %), which form the core of the concepts’ sphere. The nuclear zone is manifested by the adjective hilarus (hilaris) borrowed from the Greek language and its derivatives (hilare, hilaritudo) (12 %), as well as the noun voluptas (13 %). Peripheral are the means of secondary nomination, which actualize the concept of JOY in the appropriate context. The context at the macro level, which is the main criterion in the absence of other markers, plays an extremely important role in the implementation of the analyzed concept.
WORD-FORMATION IN MODERN GREEK: THE PECULIARITIES OF PREFIXATION
Authors:   Ivan Franko Lviv National University, Kuibida Khrystyna
Published: February 2022

The article analyzes the features of Greek prefixation as one of the ways of affix word formation. In order to reveal the complete picture concerning the origin of specific prefixes, their morphological and semantic changes in comparison with the ancient Greek language, and to reveal the emergence of new affixes, besides the synchronic the diachronic approach was used in the work. On the basis of the main theoretical concepts of word-forming paradigmatics several word-forming types and paradigms, possible structural models of derivatives in Greek are considered. Greek prefixes are divided into two types: inseparable and autonomous in origin (homonymous prepositions or adverbs that function independently in Greek). Among the autonomous units prefixes of prepositional origin are the most numerous. The process of prefixization is divided into pure prefixation and prefixation-suffixational / inflectional method. Greek pure prefixation is identified with compounding due to the same formal and functional features. Derivatives formed by the other method usually transmit the forming base into another grammatical category with the appropriate lexical meaning. The process of prefixization depends on both prefixes and the forming stem. Greek forming stems of prefixational derivatives are classified into free and bound. Prefixes can be combined with different classes of words. The greatest variety of prefixes of prepositional origin, as noted in the paper, is combined with verbs, and inseparable particles – mostly with noun bases. Due to the secondary derivation a double prefixation of the forming stem can take place. Besides the systematization of the main features of Greek prefixes, the article analyzes the evolution of prefixization on the basis of five types of prefixes. In the result of reconsideration, as noted in the paper, prefixes or prefixoids were formed on the basis of both grammatical and lexical elements.

Authors: Trotsenko V. V.
Published: February 2022

Two-steps restoration of knee joint function enables first to eliminate the flexion deformity by mobilization and then gradually to elongate the posterior anatomic structures of fibrous ankylosing knee joint. For the management the hinged distraction apparatus is used. In bone flexion ankylosis of the knee joint the osteotomy is performed along the line of the union of femur with the patella and tibia followed by gradual extension of the knee joint using hinged distraction apparatus. During the second step of the surgery the restoration of the whole synovial space of the knee joint including the articular cartillage is achieved. Conception of the articular cartillage restoration has been based and formulated and the leading role is given to arthroplasty using preserved costal cartillage in complex with the irrigation of knee joint through the drain loop. This two-steps procedure preserves the relation-ship of articular surfaces at most and enables to achieve functional and weightbearing knee joint. Long term results of the surgical treatment of 35 ankylosing knee joints in 28 patients with rheumatoid arthritis are presented. The dependence of treatment efficacy on the patients age and type of ankylosis is detected. Efficiency of the treatment ranged from 22,8% to 26,2%.

Authors: Volkov S. E. , Maksimov I. A. , Zakharov E. S.
Published: February 2022

Treatment results of club foot correction by Zatsepin in 88 children (134 deformed foot) were analyzed clinically and by X-ray method. It was shown that in high number of cases the surgery by Zatsepin did not allow to achieve the total bone reposition in the middle and posterior zones of the foot that resulted in frequent recurrence of club foot . Taking into account all those aspects the operation of periastragalar reposition was elaborated. The method consisted of total restoration of normal interrelation of the calcaneous, cuboid, scapoideus and talus foot bones with their fixation in the position of achieved correction by Kirshner pins. The operation was performed in 20 children with typical club foot (31 deformed foot). Follow up ranged from 1 year 2 months to 4 years 10 months and showed only good and satisfactory results.

Authors: Salgaonkar Sheetal S. , Allen Leigh , Zimmerman Daniel
Published: February 2022

Background and Objective.—The traditional role of the insurance medical director is evolving. RGA surveyed insurance medical directors to provide an overview of their roles, skill sets, future trends, and their increasing and changing contributions to the insurance industry in recent years and throughout the current pandemic.

Method.—RGA conducted a first-of-a-kind global survey of medical directors in the insurance industry. The online survey took place from April to June 2021 and had seven key sections: medical experience and qualifications, roles and responsibilities, underwriting and claims capabilities, adapting to change, disease and product trends in insurance, challenges, and future opportunities. Globally, 124 insurance medical directors from 84 companies participated in the survey.

Results.—Respondents are an experienced group of medical directors, with 88% active in the medical profession for 10 years or more. Eighty-seven respondents (70%) dedicate the majority of their time to providing technical medical expertise. Forty-eight percent of medical directors were involved in medical issue briefings prior to the pandemic, and that number increased to 63% during the pandemic. Three of every five respondents (60%) reported a shift in underwriting to an emphasis on more competitive decisions, e-underwriting, and data analytics, while for claims practices, 35% reported a shift to more decisions being challenged and increasing complexity of claims and products. In addition, 31% of insurance medical directors are involved in product development on a regular basis. Only 50% of respondents reported a high or moderate level of investment from employers for training and development with their companies. Forty-three percent of survey respondents are interested in a change of role, especially those with less than 15 years of experience in the insurance industry. Medical directors see data and analytics (50%) as the largest area of development for future growth. Eighty-eight percent of participants surveyed believe that the future role of the medical director in the life and health insurance industry is promising.

Conclusion.—The future of the medical director role will require more strategic responsibilities, greater product development expertise, and stronger data and analytics skills to support insurer needs. It will be important for insurance medical directors to engage in conversations with their employers to discuss their current and emerging roles.

The paper deals with the connection between accidents and occupational diseases due to the weak application of ergonomics in business practice. Applying the principles of ergonomics in the day-to-day running of companies in primary prevention makes it possible to prevent the occurrence and exacerbation of difficulties in the musculoskeletal system of the employees concerned, which can ultimately avert the development of occupational diseases and increase occupational accidents. Ergonomics primarily addresses work environment factors that are cumulatively pathogenic, so their impact on employees will only become apparent after a specific exposure time. In contrast, occupational safety and health focus primarily on thermal and traumatogenic factors of the work environment, which can cause an employee an occupational injury of varying severity or result in death. To comprehensively cover the effects of all work environment factors on employees, the work environment and the work activity itself must be assessed from both occupational health and safety and ergonomics. The observance of ergonomic principles in the solution of workplaces makes it possible to prevent many different costs related to the occurrence of accidents at work and occupational diseases. In most cases, however, these are cost-effective solutions whose effect is not immediately visible, so they are more likely to be reached by companies that apply sustainability principles or have a positive experience of the past. The article focuses on the need to implement ergonomic principles in business practice, such as preventing occupational accidents and developing occupational diseases.

Este artículo presenta las primeras experiencias de nuestro equipo de investigación en el desarrollo de robots nadadores tipo flagelo helicoidal de pequeñas dimensiones (de unos pocos centímetros) capaces de navegar en un fluido en condiciones de bajo número de Reynolds. Se presentan dos prototipos de robots que difieren entre sí principalmente en la forma de actuación: robot nadador con actuación magnética externa, cuyo desplazamiento es posible gracias a un imán permanente en rotación, y robot nadador autopropulsado, mediante un motor de pequeñas dimensiones. Se describen tanto los prototipos desarrollados como las plataformas de prueba asociadas, así como los primeros experimentos realizados. El principal objetivo es demostrar que la actuación de los robots funciona, mientras que la propulsión de los mismos es una cuestión más delicada que requiere de una profundización e investigación mayor.

Coordinación UAV-UGV para tareas de Búsqueda y Rescate
Authors: Rodríguez Palafox Pablo , Garzón Oviedo Mario , Barrientos Cruz Antonio
Published: February 2022

Se presenta un sistema autónomo de Búsqueda y Rescate basado en la coordinación entre un UAV y un UGV (este último funcionando como plataforma móvil de aterrizaje). El vehículo aéreo debe localizar el objetivo en base a una imagen aérea, seguirlo y aterrizar sobre él cuando así le sea indicado. El algoritmo de seguimiento y aterrizaje está basado en la combinación de un regulador PID con un algoritmo de predicción (basado este último, a su vez, en un filtro de Kalman) con el que se van obteniendo las posiciones futuras de la plataforma. Ello facilita el seguimiento y, principalmente, el aterrizaje, ya que el UAV puede posicionarse ligeramente por delante de la plataforma de aterrizaje momentos antes de la aproximación final y así poder completar con éxito el aterrizaje.

Los avances tecnológicos en el ámbito del control y la automatización han permitido la puesta en marcha de las llamadas aplicaciones sensibles al contexto. Estas aplicaciones demandan flexibilidad para evolucionar a medida que lo haga el contexto (adaptabilidad), así como para evitar interrupciones del servicio en el caso de fallos en nodos (disponibilidad). La solución propuesta en este trabajo hace frente, entre otros, a estos requisitos de flexibilidad mediante un middleware basado en multiagentes que además de cumplir con los requisitos de adaptabilidad asegura la disponibilidad del sistema incluso para aplicaciones con estado.

Chronic thromboembolic pulmonary hypertension (CTEPH) is a rare complication of acute pulmonary embolism, either symptomatic or not. The occlusion of proximal pulmonary arteries by fibrotic intravascular material, in combination with a secondary microvasculopathy of vessels < 500 μm, leads to increased pulmonary vascular resistance and progressive right heart failure. The mechanism responsible for the transformation of red clots into fibrotic material remnants has not yet been elucidated. In patients with pulmonary hypertension, the diagnosis is suspected when a ventilation/ perfusion lung scan shows mismatched perfusion defects, and confirmed by right heart catheterisation and vascular imaging. Today, in addition to lifelong anticoagulation, treatment modalities include surgery, angioplasty and medical treatment according to the localisation and characteristics of the lesions. This statement outlines a review of the literature and current practice concerning diagnosis and management of CTEPH. It covers the definitions, diagnosis, epidemiology, follow-up after acute pulmonary embolism, pathophysiology, treatment by pulmonary endarterectomy, balloon pulmonary angioplasty, drugs and their combination, rehabilitation and new lines of research in CTEPH. It represents the first collaboration of the European Respiratory Society, the International CTEPH Association and the European Reference Network-Lung in the pulmonary hypertension domain. The statement summarises current knowledge, but does not make formal recommendations for clinical practice.

Blood eosinophil count is associated with measurements have been used as biomarkers for eosinophil-related airway inflammation. Eosinophils are found in the airways, tissues, and blood during stable disease or acute exacerbations of COPD (AECOPD). The modified Medical Research Council dyspnea scale (mMRC) and COPD assessment test (CAT) scores have been shown to be useful as novel tools for evaluating these aspects of COPD.The aim. This study aimed to investigate the relation of blood eosinophil count with the assessment scales and the number of emergency department (ED) admissions in patients with acute exacerbations COPD. Study Design. Cross-Sectional Study. Methods. Based on eosinophil count, the patients were divided into two groups: < 300 cells μL−1 and ≥ 300 cells μL−1. For these two groups, the relationship between acute exacerbation and the number of admissions to ED, the number of hospitalizations in the last one year, CAT score, mMRC score, and comorbid diseases were analyzed. Results. 166 patients was mean age 69.0, 126 (75.9%) male. Patients with high eosinophil count had fewer ED admission compared with those with low eosinophil count(5 and 10, respectively), Median mMRC score of patients with low eosinophil count was significantly higher compared with that of patients with high eosinophil count(p = 0.022).The difference between the median CAT scores of the two groups was not statistically significant. A statistically significant, negative relationship was found between the eosinophil count and mMRC scores (r = −0.219; p = 0.005). Conclusion. High levels of eosinophilia in patients presenting with AECOPD are associated with low mMRC score. Also, although not statistically significant, the number of admissions to the ED may be lower.
