Variables fisiológicas del “componente metabólico” del estado ácido base y mortalidad en pacientes de cuidados intensivos
Authors: Castillo-Rodríguez Cristian Alejandro , Diaztagle-Fernández Juan José , Marcelo-Pinilla Luis Alejandro
Published: November 2021

Introducción. La acidosis metabólica es una condición fisiopatológica frecuente en pacientes críticos. Esta alteración es evaluada mediante diferentes variables fisiológicas; sin embargo, su valor pronóstico aún no está bien definido.
Objetivo. Evaluar la asociación entre variables del componente metabólico del estado ácido base (EAB) y mortalidad a 28 días en pacientes de una unidad de cuidados intensivos (UCI) en Bogotá D.C., Colombia.
Materiales y métodos. Estudio de cohorte prospectivo realizado en 122 pacientes hospitalizados en una UCI entre enero y junio de 2013 y con una estancia mayor a 24 horas. Se tomaron muestras sanguíneas y gases arteriales de ingreso para el cálculo de las siguientes variables: Anion Gap (AG), Anion Gap corregido (AGc), Base exceso estándar (BEst), H+ metabólicos, Base exceso-aniones no medibles (BEua), pH, lactato, HCO3-st, Brecha de iones fuertes (BIF), puntaje Apache II, y puntaje SOFA. Se realizó un análisis bivariado, calculándose OR con un nivel de significancia de p<0.05, y luego uno multivariado, mediante un modelo de regresión logística, para identificar las variables asociadas con la mortalidad a 28 días.
Resultados. De los 122 pacientes, 33 (27.7%) fallecieron a 28 días y 51 (48.7%) eran mujeres. La edad promedio fue 46.5 años (±15.7). En el análisis bivariado, las siguientes variables se asociaron significativamente con la mortalidad a 28 días: BIF: OR=1.150 (p=0.008), BEua: OR=0,897 (p=0.023), AG: OR=1.231 (p=0.002), AGc: OR=1.232, (p=0.003), pH arterial: OR=0.001, (p=0.023), APACHE II: OR=1.180 (p=0.001), HCO3- st: OR=0.841 (p=0.015). En el análisis multivariado, solo el puntaje APACHE II se asoció significativamente con la mortalidad a 28 días: OR=1.188 (p=0.008).
Conclusión. Las variables fisiológicas que evalúan el componente metabólico del estado ácido-base, tanto las del modelo de Henderson, como las del modelo de Stewart, no se asociaron significativamente con la mortalidad a 28 días en la población de estudio.
Design and implementation of a digital textbook about physical agents as a learning resource in the training process of Chilean physical therapy students in the context of the COVID-19 pandemic
Authors: De la Barra-Ortiz Hernán Andrés , Gómez-Miranda Luis Adrián
Published: November 2021

The COVID-19 pandemic has had a strong impact on education, forcing the implementation of distance learning methodologies using information and communication technologies (ICT).
The digital textbook is a didactic resource used to guide the training process of students; besides, its interactivity allows systematic work, favoring metacognition and the construction of self-learning.
The aim of this paper is to describe, through a descriptive cross-sectional design, the design, review, digitalization and implementation phases of a digital textbook about physical agents as a learning resource to support distance education in the training process of physical therapy students enrolled in the physical agents course offered by Universidad Andres Bello in Santiago, Chile, in the context of the human mobility restriction measures implemented due to the COVID-19 pandemic.
The textbook consists of thirteen thematic sections and once it was reviewed and validated by peers and by the editorial committee of the university it was digitalized and indexed into the digital resource database of the university, where it was made available to the entire cohort of students enrolled in the physical agents course during the first semester of 2020 (n=115).The digital textbook was successfully implemented as a didactic resource to guide the autonomous and distance learning of students during the time human mobility restriction measures were established in Chile due to the pandemic. Future studies should focus on reporting the students’ satisfaction and perception of this tool and its effect on learning outcomes in order to obtain effective feedback.
Estabelecendo diálogo da Educação Profissional e Tecnológica com o projeto “Educação Sanitária na Escola” da Secretaria da Agricultura do RS

Published: November 2021

A Secretaria da Agricultura, Pecuária e Desenvolvimento Rural do Rio Grande do Sul (SEAPDR) conta com o projeto “Educação Sanitária na Escola”, criado em 2010, que tem fiscais estaduais agropecuários como agentes disseminadores de Educação Sanitária em Defesa Agropecuária em escolas de ensino básico. O documento orientador deste projeto passou por uma revisão, sendo republicado em 2018. Este artigo é oriundo de pesquisa documental, qualitativa, de caráter exploratório, que se propõe a apresentar uma análise comparativa entre as duas versões do documento, seguindo categorização conforme Bardin (2011). Por meio da análise documental, traça relações com as bases conceituais da Educação Profissional e Tecnológica (EPT), principalmente os conceitos de trabalho como princípio educativo e a formação humana integral, conforme Gramsci (2001), Saviani (2007), Ciavatta (2009, 2014), Ramos (2008) e Freire (1987). Como resultado, verifica-se que o “Educação Sanitária na Escola” estabelece um diálogo consistente com as bases teóricas da EPT. A análise do documento orientador sob este viés contribuirá na elaboração de um site orientativo para auxiliar na ampliação da base de atuação do projeto.

Analysis of the seminar of creative music exercises
Authors: Fekete Anikó , Fehérvári Anikó , Bodnár Gábor
Published: November 2021

During the research entitled Teaching Creative Music, the focus is on getting to know creative music, which is becoming more and more widespread in Hungary, however using it, but still takes up little space in our music education, and its impact in high school and university environments is limited. The Kodály Concept contains a number of well-established practices also László Sáry’s collection of Creative Music Exercises (Sáry, 1999), mainly evoking Christian Wolff and John Cage, evoking the work of Stockhausen, also works well, but there is no teaching aid for the secondary school classes (9-12) based on different combinations of systematic vocal and rhythmic tasks – although in the 2017 NAT [“National Curriculum”], creative music activity as a reproduction is included as a requirement among the development tasks. There is also less experience among those pursuing higher music studies in terms of methodological preparation at the national level.

We believe that much more student-based assignments should be used in high school singing and music education so that their classroom motivation and musical creativity can develop further, and their subject-related knowledge deepen.

We are interested in the “rehabilitation” of this field, as there are a lot of opportunities in the creative music exercises, during which repetitive activity and musical creativity are essential, and Odena and Welch have already studied the latter (Odena–Welch, 2007).

Music pedagogical research supports the need to study the field, as high school students are undermotivated in their lessons and their musical creativity is not sufficiently exploited (Deliège–Wiggins, 2006).

In this article, we would like to explore an analysis of some of the practices of a creative music course over a semester in terms of how student activity and creativity changed during the 9 hours of the practice (measured with 3 groups per week). For all of this, we also use elements of Teachout and McKoy’s model, who examined music teacher attributes in terms of teacher success and failure.

Learning by expanding is a model of learning that enables an analysis of how learning occurs in an educational community where relationships between its members and participation are essential for social transformation. With this concept as a starting point, a research methodology has been developed which aims to describe, record, and analyze how the process of learning by expanding can occur in different systems of activity; and/or, discover obstacles, difficulties, and challenges.
Investigating the Neoliberal Educational Agenda: The Effect of Reform Contexts on Teacher Agency
Authors: Tinn Maarja
Published: November 2021

During the transition to democratic society a neoliberal educational agenda was introduced to guide the reform process in Estonia. Documentary analysis was conducted for this research and six periods emerged, which showed that expectations were placed on teachers that assumed the existence of teacher agency, while the reform context didn’t support its emergence. Evidence of change can be seen in the last periods, when also a significant dichotomy arises.

Sports infrastructure for football in Częstochowa in the interwar period
Authors: Kościański Krzysztof
Published: November 2021

The article presents the sports infrastructure for football in Częstochowa in the interwar years. The article was written mainly on the basis of archival and press sources. The conducted research shows that in Częstochowa in the interwar period, several sports facilities adapted to playing foot-ball were built. Both the quantity and quality, compared to the national scale, was insufficient. Investors in sports infrastructure were municipal governments, the army andstate authorities. Sports clubs and associations also tried to create sports facilities. In Częstochowa, the first munic-ipal soccer field was opened in 1923 in the ‘Zawodzie’district. A representative sports facility of regional importance was put into operation in the early 1930s. The “Ogniska Obrony Niepod-ległości” Stadium named after Marshal Józef Piłsudski was considered to be one of the leading ones in the ‘Kielce’Province. However, it could not compete with the best facilities in Poland in terms of infrastructure. A national and international stadium could be a facility that was to be built atOlsztyńska street. Despite the commenced works, the investment was not completed due to lack of money and the outbreak of World War II. In the years 1918-1939, several pitches for the football discipline were built. Local sports clubs were mostly responsible for them.
Enfolding the Hand, Entrancing the Eye: Erica Baum’s Dog Ear
Authors: Hanick Riley Llewellyn
Published: November 2021

This essay situates Erica Baum’s Dog Ear (Ugly Duckling Presse 2011) within the history of the artist’s book. It does so by introducing her ongoing series, begun over a decade ago, in which Baum makes the quotidian act of folding the corner of a book’s page into a sculptural intervention, reorienting and “reauthoring” source texts into works of concrete poetry. While photographs from this series have found a wide reception within the art world, their movement away from the gallery wall and (back) into the codex has permitted them to take on new dimensions of meaning. For critics more intent on approaching these images as poems, the challenge of rendering Dog Ear’s lineation has been met with consistently unsatisfying results. In taking up a different framework – that of the artist’s book – this essay does not argue against Dog Ear as a work of poetry or, for that matter, photography. Instead, it attends to the relationships between word and image as they are reconfigured by the gesture of folding, which both repeats and crystalizes moments of exposure and concealment. Materiality and seriality intertwine to sustain the unsettled, self-renewing pages against the backdrop of the book as object.

Authors: Ficco Cecilia , Luna Valenzuela Jonathan
Published: November 2021

El objetivo fundamental de este trabajo es analizar la divulgación de información no financiera sobre capital intelectual (CI) en el reporte integrado (RI). Para dar cumplimiento al objetivo planteado se realiza un estudio descriptivo, adoptando el enfoque de estudio de caso, que permite analizar, en las prácticas de divulgación de información, aquella que refiere al CI y que se canaliza a través del RI. El estudio empírico se sustenta en el análisis de datos textuales y se realiza sobre una empresa perteneciente al sector financiero, pionera en la adopción del RI en el mercado de capitales argentino. Las evidencias obtenidas indican que la empresa analizada divulga información sobre CI y sus dimensiones, humana, estructural y relacional, en el RI; adoptando la estructura del marco del IIRC.  Estos hallazgos apoyan la idea de que el CI está resurgiendo como parte del RI.
La utilidad de los informes de sostenibilidad en entidades públicas y privadas en Colombia
Authors: Suárez-Rico Yuli Marcela , Gómez-Villegas Mauricio , García-Benau María Antonia
Published: November 2021

El aumento en la divulgación de información social y medioambiental (de sostenibilidad) genera preguntas sobre su utilidad y materialidad, lo que implica conocer las expectativas de los stakeholders. El stakeholder engagement permite señalar que la participación de los grupos de interés no solo debe centrarse en la producción de la información en las empresas, sino también en la definición de los marcos y estándares que estructuran estos reportes. Este trabajo busca caracterizar las expectativas y la percepción que tienen diversos stakeholders, sobre la utilidad de los informes de sostenibilidad emitidos por organizaciones públicas y privadas en Colombia. A partir de dos cuestionarios respondidos por 62 gestores, preparadores, auditores, reguladores, estudiantes y profesores, se identifican temas que los marcos más extendidos (GRI) no incluyen y que incrementarían la materialidad de esta información en Colombia: acciones para la paz, lucha contra la corrupción y la desigualdad, información para los ciudadanos, entre otros.

Published: November 2021

La información integrada se presenta como un fenómeno de reciente auge que permite a diversas organizaciones informar de una manera simplificada pero completa sobre su gestión respecto a diversos tipos de capitales. Aunque predominantemente se ha desarrollado en las empresas privadas, en el ámbito internacional viene reconociéndose que otro tipo de organizaciones como las universidades, divulgan esta información o cuentan con la necesidad y el potencial para ello. Este trabajo tiene como objetivo analizar en qué medida la información solicitada para construir un reporte integrado de acuerdo con los requerimientos del Marco Conceptual del IIRC, ya está revelada en internet por las universidades colombianas incluidas en el ranking QS 2019. Para ello, se construyó un índice de cumplimiento a partir de una lista de verificación. Los resultados sugieren que el nivel de divulgación es heterogéneo entre universidades, siendo el modelo de negocio la unidad de análisis más divulgada.
Optimization of ozone concentration and storage time in green asparagus (Asparagus officinalis L.) using response surface methodology
Authors: Pretell Carla , Márquez-Villacorta Luis , Siche Raúl , Hayayumi-Valdivia María
Published: November 2021

Background: Asparagus (Asparagus officinalis L.) green is a vegetable with a great demand worldwide, and likewise, it is highly perishable due to its high respiration rate that accelerates its senescence. Disinfection of vegetables after their harvest is an obligatory practice that can reduce losses by decomposition due to the attack of microorganisms. Therefore, it is vital to preserving its microbiological and sensory characteristics to reach the final consumer. Objective: To evaluate the effect of gaseous ozone (0 to 10 ppm) and storage time (0 to 30 days) on phenol content, overall appearance, count of molds, psychrophilic bacteria, and viable mesophilic aerobes. Methods: the response surface methodology was used, applying a rotatable central composite design. Results: The results indicated that there was a significant influence (p <0.05) of the independent variables on the characteristics studied, as well as an adequate lack of fit of the quadratic regression model (p> 0.05). By means of the contour superposition technique, it was determined that the optimal conditions for the highest retention of phenol content (16.99 mg/g) and overall appearance (7.61 points) and lower counts of viable aerobic mesophilic bacteria (5.3 x 103 CFU/g) they corresponded to 10 ppm of gaseous ozone up to 25.91 days of storage, with adequate quality characteristics in the shoots. Conclusion: the region of interest was determined for optimal retention of phenol content and overall appearance, and a lower count of viable aerobic mesophilic bacteria in green asparagus during postharvest, suggesting to use the initial application of ozone gas at 10 ppm allowing 25.9 days storage at 1 °C. The results indicate that this technology is a good alternative in the conservation of fresh vegetables.
Investigating Algorithmic Misconceptions in a Media Context: Source of a New Digital Divide?
Authors: Zarouali Brahim , Helberger Natali , De Vreese Claes H.
Published: November 2021

Algorithms are widely used in our data-driven media landscape. Many misconceptions have arisen about how these algorithms work and what they can do. In this study, we conducted a large representative survey (N = 2,106) in the Netherlands to explore algorithmic misconceptions. Results showed that a significant part of the general population holds (multiple) misconceptions about algorithms in the media. We found that erroneous beliefs about algorithms are more common among (1) older people (vs. younger people), (2) lower-educated people (vs. higher-educated), and (3) women (vs. men). In addition, it was found that people who had no specific sources to inform themselves about algorithms, and those relying on their friends/family for information, were more likely to have algorithmic misconceptions. Conversely, media channels, school, and having one’s own (online) experiences were found to be sources associated with having fewer algorithmic misconceptions. Theoretical implications are formulated in the context of algorithmic awareness and the digital divide. Finally, societal implications are discussed, such as the need for algorithmic literacy initiatives.
Algorithmic Self-Tracking for Health: User Perspectives on Risk Awareness and Coping Strategies
Authors: Festic Noemi , Latzer Michael , Smirnova Svetlana
Published: November 2021

Self-tracking with wearable devices and mobile applications is a popular practice that relies on automated data collection and algorithm-driven analytics. Initially designed as a tool for personal use, a variety of public and corporate actors such as commercial organizations and insurance companies now make use of self-tracking data. Associated social risks such as privacy violations or measurement inaccuracies have been theoretically derived, although empirical evidence remains sparse. This article conceptualizes self-tracking as algorithmic-selection applications and empirically examines users’ risk awareness related to self-tracking applications as well as coping strategies as an option to deal with these risks. It draws on representative survey data collected in Switzerland. The results reveal that Swiss self-trackers’ awareness of risks related to the applications they use is generally low and only a small number of those who self-track apply coping strategies. We further find only a weak association between risk awareness and the application of coping strategies. This points to a cost-benefit calculation when deciding how to respond to perceived risks, a behavior explained as a privacy calculus in extant literature. The widespread willingness to pass on personal data to insurance companies despite associated risks provides further evidence for this interpretation. The conclusions—made even more pertinent by the potential of wearables’ track-and-trace systems and state-level health provision—raise questions about technical safeguarding, data and health literacies, and governance mechanisms that might be necessary considering the further popularization of self-tracking for health.
When Algorithms Recommend What’s New(s): New Dynamics of Decision-Making and Autonomy in Newsgathering
Authors: Cools Hannes , Van Gorp Baldwin , Opgenhaffen Michaël
Published: November 2021

Newsroom innovation labs have been created over the last ten years to develop algorithmic news recommenders (ANR) that suggest and summarise what news is. Although these ANRs are still in an early stage and have not yet been implemented in the entire newsroom, they have the potential to change how newsworkers fulfil their daily decisions (gatekeeping) and autonomy in setting the agenda (agenda-setting). First, this study focuses on the new dynamics of the ANR and how it potentially influences the newsworkers’ role of gatekeeping within the newsgathering process. Second, this study investigates how the dynamics of an ANR could influence the autonomy of the newsworkers’ role as media agenda setters. In order to advance our understanding of the changing dynamics of gatekeeping and agenda-setting in the newsroom, this study conducts expert interviews with 16 members of newsroom innovation labs of The Washington Post, The Wall Street Journal, Der Spiegel, the BBC, and the Bayerische Rundfunk (BR) radio station. The results show that when newsworkers interact with ANRs, they rely on suggestions and summaries to evaluate what is newsworthy, especially when there is a “news peak” (elections, a worldwide pandemic, etc.). With regard to the agenda-setting role, the newsworker still has full autonomy, but the ANR creates a “positive acceleration effect” on how certain topics are put on the agenda.

Background. The standard treatment for giant-cell tumors of the bone includes radical surgery. However, specific anatomical location of the tumor and/or its spread may hinder its complete excision or result in poor functional outcomes. Currently, combination treatment that includes preoperative denosumab and surgery is preferable. It saves patients’ lives and improves their quality of life. Reduction of local recurrence rate by combination therapy for giant-cell tumors of the bone is being actively studied now.

Objective – to analyze treatment outcomes of patients with giant-cell tumors of the bone, including those who received combination treatment that included preoperative therapy with denosumab followed by surgery.

Materials and methods. This study included 277 patients with giant-cell tumors treated in N.N. Blokhin National Cancer Research Center between 2005 and 2020. The mean duration of follow-up was 56 months. Study participants were divided into two groups. Group 1 included patients who received surgical treatment alone (n = 212), whereas Group 2 comprised patients who received combination treatment (n = 65). Neoadjuvant therapy included subcutaneous denosumab 120 mg on days 1, 8, 15, and 28, then every 4 weeks until stable effect. There were two variants of surgical treatment: radical (removal by a single block or segmental resection with defect replacement, with or without fixation) and non-radical (excochleation or marginal resection with defect replacement, with or without fixation).

Results. During treatment, patients in Group 2 had a significantly milder pain syndrome (assessed both using the visual analog scale for pain and Watkins scale) compared to Group 1. In case of radical surgery, the incidence of local recurrence was 12 % and 0 % in Groups 1 and 2, respectively; the difference was significant (р <0.05). Tumor location and volume of surgery played an important role in disease recurrence (р <0.05). The incidence of complications after radical surgery was 36.9 % and 12.5 % in Groups 1 and 2, respectively; the difference was significant (р <0.05). In addition to that, neoadjuvant therapy with denosumab substantially reduced the duration of surgery and blood loss in patients with challenging anatomical location of the tumor (р <0.05).

Conclusion. Combination treatment for giant-cell tumors that includes neoadjuvant therapy with denosumab reduces the risk of recurrence, duration of surgery, blood loss, and the risk of postoperative complications. However, it is important to consider tumor location and the volume of surgery. Since the disease is quite rare, further study of long-term efficacy and safety of combination treatment for giant-cell tumors, including rare ones and those with challenging anatomical location, is necessary.
Using Metrics for Risk Prediction in Object-Oriented Software: A Cross-Version Validation
Authors:   Software Engineering Research Laboratory, Department of Mathematics and Computer Science, University of Quebec, Trois-Rivie res, Canada, Moudache Salim , Badri Mourad
Published: November 2021

This work aims to investigate the potential, from different perspectives, of a risk model to support Cross-Version Fault and Severity Prediction (CVFSP) in object-oriented software. The risk of a class is addressed from the perspective of two particular factors: the number of faults it can contain and their severity. We used various object-oriented metrics to capture the two risk factors. The risk of a class is modeled using the concept of Euclidean distance. We used a dataset collected from five successive versions of an open-source Java software system (ANT). We investigated different variants of the considered risk model, based on various combinations of object-oriented metrics pairs. We used different machine learning algorithms for building the prediction models: Naive Bayes (NB), J48, Random Forest (RF), Support Vector Machines (SVM) and Multilayer Perceptron (ANN). We investigated the effectiveness of the prediction models for Cross-Version Fault and Severity Prediction (CVFSP), using data of prior versions of the considered system. We also investigated if the considered risk model can give as output the Empirical Risk (ER) of a class, a continuous value considering both the number of faults and their different levels of severity. We used different techniques for building the prediction models: Linear Regression (LR), Gaussian Process (GP), Random forest (RF) and M5P (two decision trees algorithms), SmoReg and Artificial Neural Network (ANN). The considered risk model achieves acceptable results for both cross-version binary fault prediction (a g-mean of 0.714, an AUC of 0.725) and cross-version multi-classification of levels of severity (a g-mean of 0.758, an AUC of 0.771). The model also achieves good results in the estimation of the empirical risk of a class by considering both the number of faults and their levels of severity (intra-version analysis with a correlation coefficient of 0.659, cross-version analysis with a correlation coefficient of 0.486).

Published: November 2021

The ability to generate data has never been as powerful as today when three quintile bytes of data are generated daily. In the field of machine learning, a large number of algorithms have been developed, which can be used for intelligent data analysis and to solve prediction and descriptive problems in different domains. Developed algorithms have different effects on different problems.If one algorithmworks better on one dataset,the same algorithm may work worse on another data set. The reason is that each dataset has different features in terms of local and global characteristics. It is therefore imperative to know intrinsic algorithms behavior on different types of datasets andchoose the right algorithm for the problem solving. To address this problem, this papergives scientific contribution in meta learning field by proposing framework for identifying the specific characteristics of datasets in two domains of social sciences:education and business and develops meta models based on: ranking algorithms, calculating correlation of ranks, developing a multi-criteria model, two-component index and prediction based on machine learning algorithms. Each of the meta models serve as the basis for the development of intelligent system version. Application of such framework should include a comparative analysis of a large number of machine learning algorithms on a large number of datasetsfromsocial sciences.

Gastrin is considered one of the most important hormones regulating physiological processes. Trophic and proliferative effects of high gastrin levels on gastric mucosa are well known. Butinformation about gastrin effects on the colon is rather fragmentary and contradictory. In this study, ultrastructural changes in the proximal part of the colon induced in rats by chronic hypergastrinemia were analyzed by transmission electron microscopy. Experimental omeprazole-induced hypergastrinemia was reproduced using daily injections of proton pump inhibitor omeprazole in rats, resulted in hypersecrestion of gastrin by G-cells of stomach. Growth of gastrin level in the blood plasma was checked using radioimmunoassay method. Prolonged hypergastrinemia has been shown to be associated with increased cell proliferation and appearance of cellular atypia in the large intestine mucosa. The number of undifferentiated cells increased prominently. Intercellular contacts between such cells are altered, the space between them is unevenly expanded. Their organelles were observed significantly reduced, mitochondria contained destroyed crysts and signs of edema. Endocrinocytes did not contain their typical secretory granules. Cell nuclei were small, electron-dense, with invagination. In addition, numerous microorganisms were revealed in the intestinal lumen, as well as their invasion into the mucosa. Those ultrastructural changes were indicate increased hyperplastic processes and impaired cell differentiation in the epitheliocytes of large intestine. Therefore, long-term experimental hypergastrinaemia causes dysplastic changes in the large intestine mucosa of rats.
Multifactorial interventions to prevent falls in older adults
Authors: Богданова Tatiana A.
Published: November 2021

BACKGROUND: Falls are one of the most common syndromes in old age. An estimated 646,000 deaths from falls occur each year worldwide. Moreover, most fatal falls occur in people over 65 years of age. Most falls are the result of the interaction of several factors.
AIMS: To examine the long-term effectiveness of multifactorial interventions in preventing falls in elderly and senile patients.
MATERIALS AND METHODS: A sample of patients territorially attached to the Family Medicine Center of the North-Western State Medical University named after I.I. Mechnikov was established four years ago. Individual fall prevention programs were developed for all study participants (n = 260) because they had different falls risk factors. Patient follow-up was continued for 12 months. The results of the multifactorial intervention were evaluated after 12 months and after 3 years, 2 times in total, the last study in a random subsample of patients (n = 84). Aging asthenia screening, questionnaires, assessment of emotional status, and presence of sleep disturbances were performed to assess the risk of falls. The effectiveness of multifactorial interventions was assessed based on repeated assessment of risk factors for falls.
RESULTS: Participants with a history of falls were significantly more likely to have symptoms of depression, anxiety, symptoms of frailty, visual and hearing impairment (p 0.05). On average, each participant in the group with falls had 6.1 2.1 risk factors for falls and 3.8 2.3 in the group without falls (p = 0.000). During the follow-up period after the interventions, the incidence of falls decreased 9-fold after one year (from 28.5% to 3.1%) and then increased to 23.8%. All patients who fell after the multifactorial intervention had a history of cognitive impairment and falls. In addition, in the group of patients with falls, fall risk factors such as low levels of physical activity, hearing impairment, and the presence of a traumatic environment at home were not eliminated. As a result of the interventions, fear of falls disappeared in 9 patients, 95% CI (2.35-65.89), p = 0.039.
CONCLUSIONS: The study demonstrated a decrease in the effectiveness of multifactorial interventions to prevent falls at three years. A less persistent effect was seen in patients with a history of falls. A history of falls, symptoms of frailty, complaints of fear of falls, sleep disturbances, and anxiety symptoms were factors that increased the risk of falls. Individualized fall prevention programs resulted in decreased fear of falls.

Published: November 2021

The implications on leadership of shifting from a conventional vision, in which the Organization looks like a machine and the leader is in charge of promoting its stability and decide the path to take, to the recent advances, in which Organization is assumed as a complex system that through selforganization generates new ways to adapt. This perspective involves deep changes in the leadership concept which is less focused on the leader and more on the leadership processes that result in the system as a product of the agent’s interaction. Through a collaborative leadership, leaders must take the Organization to a far from balanced stage in order to promote learning and innovation, being these, key aspects to the corporate sustainability.

Los impuestos en la época de la independencia, su impacto social, evolución e implicaciones en el sistema tributario actual
Authors: FAJARDO CALDERÓN CONSTANZA LORETH , SUÁREZ AMAYA DORA CECILIA
Published: November 2021

La evolución histórica de los tributos en Colombia se encuentra inmersa en una serie de acontecimientos que hacen parte de la historia patria. El sistema impositivo colombiano fue implementado por España durante la colonización a semejanza del aplicado en dicho país; el incremento de los impuestos para financiar sus actividades y las guerras que sostenía por la lucha de territorios hizo que los habitantes de las colonias se sublevaran en contra del régimen opresor; un claro ejemplo de ello es la rebelión de los Comuneros, la cual se genero debido al incremento del impuesto de la Armada de Barlovento. Los constantes abusos y la discriminación a la que estaban sometidos por parte de los españoles desencadenaron una serie de hechos que posteriormente llevaron a la independencia; al instalarse el nuevo gobierno una de las primeras reformas realizadas en esta materia fue abolir algunos impuestos, como el Tributo de Indios. Conocer el origen y evolución del sistema impositivo actual en Colombia es de gran utilidad para realizar un estudio más profundo del tema y mejorar la comprensión del mismo, desde un contexto no sólo político y económico sino también social y cultural. Desde épocas antiguas los tributos han constituido la principal fuente de ingresos del Estado, incluso en la prehistoria estos hacían parte de la religión y sus creencias, lo cual permite evidenciar que han hecho parte de los procesos evolutivos del hombre.
