Authors: Porkhanov V. A. , Straub V. V. , Bogdanov S. B. , Mukhanov M. L. , Zaitseva S. L.
Published: February 2024

Objective. Tracheostomy is one of the most frequently performed surgical procedures in seriously ill patients in the intensive care unit and in intensive care units who require long-term mechanical ventilation. Protecting the larynx and upper airway from the complications of prolonged intubation is an important reason for tracheostomy and airway management. Early tracheostomy can reduce the dosage of sedatives used, contributes to a gradual decrease in artificial ventilation support. However, with the development of minimally invasive techniques for performing tracheostomy, the medical community raises the question of the need to choose the optimal surgical method. First, it depends on the timing of its application, the tracheostomy, the duration of the transition to independent breathing, and the behavior of patients after the procedure. The use of dilation tracheostomy can improve the aesthetic outcome of patients.

Purpose of a study: Comparative evaluation of the effectiveness of performing tracheostomy using traditional and modified technology at different times of mechanical ventilation in seriously ill surgical and therapeutic patients in the intensive care unit.

Material and methods. The study was based on an analysis of the results of treatment of 331 patients (212 men (64 %) and 119 women (36 %)) aged from 18 to 92 years old (average age (55,7 ± 5,2) years), who were in the intensive care unit of the Regional Clinical Hospital No. 1 named after Professor S.V. Ochapovsky (Krasnodar) for 2020–2022, in which a tracheostomy was performed to prevent cicatricial complications. The patients were divided into 2 groups. The first group included 219 patients from the intensive care unit who underwent tracheostomy using traditional technology, and the second group (112 patients) included patients who underwent tracheostomy using a modified technology.

Results. A new modified technology for performing tracheostomy in seriously ill surgical and therapeutic patients in the intensive care unit has been improved and developed. Objectively substantiated and noted the advantages and disadvantages of the modified tracheostomy technology from the hemodynamic, gas transport positions, possible complications and long-term results.

Conclusion. The use of a new modified technology of tracheostomy imposition allows preventively protecting patients from the development of complications in the form of profuse bleeding in comorbid coagulopathy and against the background of the use of therapeutic dosages of anticoagulation therapy, reducing the risk of decanulation, improving functional and cosmetic results of treatment due to less skin trauma.

Solving blocking flowshop scheduling problem with makespan criterion using q-learning-based iterated greedy algorithms
Authors: Tasgetiren M. Fatih , Kizilay Damla , Kandiller Levent
Published: February 2024

This study proposes Q-learning-based iterated greedy (IGQ) algorithms to solve the blocking flowshop scheduling problem with the makespan criterion. Q learning is a model-free machine intelligence technique, which is adapted into the traditional iterated greedy (IG) algorithm to determine its parameters, mainly, the destruction size and temperature scale factor, adaptively during the search process. Besides IGQ algorithms, two different mathematical modeling techniques. One of these techniques is the constraint programming (CP) model, which is known to work well with scheduling problems. The other technique is the mixed integer linear programming (MILP) model, which provides the mathematical definition of the problem. The introduction of these mathematical models supports the validation of IGQ algorithms and provides a comparison between different exact solution methodologies. To measure and compare the performance of IGQ algorithms and mathematical models, extensive computational experiments have been performed on both small and large VRF benchmarks available in the literature. Computational results and statistical analyses indicate that IGQ algorithms generate substantially better results when compared to non-learning IG algorithms.

Authors: Khanna Ruchee , Saeed Muneerah , Manohar Chethan , K. Singh Varun
Published: February 2024

Introduction: Reticulocyte parameters obtained from the automated analyzers have gained importance not only in the classification of anemias but also in therapeutic monitoring. Their role in nutritional anemia is by far limited to monitoring the hematinic response. The present study aims to describe the distribution of various reticulocyte parameters obtained from Beckman Coulter DXH 800 in cases of nutritional deficiency anemias. Method: Reticulocyte parameters of iron deficiency anemia (IDA) (n=146), megaloblastic anemia (MA) (n=119), and mixed deficiency anemia (n=32) were compared with a non-anemic healthy control group (n=68). Independent sample T-test and one-way ANOVA were used for comparisons. Results: The RET%, MRV, IRF, MSCV, HLR%, RSF, RDWr, and RDWr-SD were significantly higher in MA than in other groups and a significant inverse correlation of Hb was seen with MRV, RDWr, and RDWr-SD. In IDA there was a significant increase in RET%, ARC, IRF, HLR%, HLR#, and RDWr, and a reduction in MRV, MSCV, and RSF. The strongest positive correlation of Hb was with RSF. In the mixed deficiency anemia group, there was an increase in RET%, ARC, IRF, HLR%, HLR#, and RDWr and a reduction in MRV, MSCV, and RSF. Cases on treatment had significantly higher RET%, ARC, and HLR# compared to those without irrespective of etiology. Conclusion: The study strengthens the utility of RSF as a marker of iron-restricted erythropoiesis, and a low RSF and higher MRV in differentiating IDA from mixed deficiency anemia. Irrespective of the etiology, RET%, ARC, HLR%, and HLR# can be utilized for monitoring therapy in nutritional anemias.

Purpose: The study aims to analyze regional health and socioeconomic inequalities in Bulgaria. Methods: An ecological epidemiological study was conducted. The 28 regions in Bulgaria were compared according to death rates due to COVID-19, the share of people 65+, availability of physicians, hospital beds for active and intensive care per 10,000 people, and the average annual salary of employed people /2021/. Data were statistically processed with SPSS v.26, the Pearson coefficient was used. Results: The death rates due to COVID-19 in Bulgaria vary widely, and the regions with the highest rates in 2021 are Kyustendil /642.440/0000/, Vidin /591.150/0000/, Montana /533.980/0000/, Gabrovo /533.480/0000/ and Vratsa /531.900/0000/. All five regions have ageing rates higher than the national average of the availability of physicians per population - lower than the average, respectively 36.60/0000, 35.50/0000, 34.90/0000, 37.60/0000 and 38.10/0000. Among the areas with high levels of death rates, Vidin stands out with very low availability of hospital beds for active and intensive treatment - 37.80/0000, but Gabrovo and Montana have higher. A moderate correlation was found between the death rate due to COVID-19 and the ageing of the population, but for other factors, no correlation was established. Conclusions: Reducing regional health inequalities in Bulgaria is one of the possible ways to control and reduce the death rate in the country, especially due to COVID-19.

La comisión de apertura en el contrato de préstamo o crédito hipotecario y su control de abusividad
Authors: López San Luis Rocío
Published: February 2024

Con el fallo emitido por la sentencia del TJUE (Sala Cuarta) de 16 de marzo de 2023, la validez de la comisión de apertura está fuera de toda duda, siempre y cuando supere los controles de transparencia y de contenido –arts. 3, 4.2.º y 5 Directiva 93/13/CEE–. El citado tribunal considera que la comisión de apertura no forma parte de la estructura del precio, quedando, por tanto, fuera del objeto principal del contrato de préstamo o crédito hipotecario. Todo ello, viene a contradecir, en parte, la doctrina fijada por el TS en la sentencia 44/2019 de 23 de enero.
Sentencias comentadas. Seguro, invalidez permanente por enfermedad común y momento del siniestro
Authors: Basozabal Arrue Xabier
Published: February 2024

La STS 195/2023, Sala Civil, de 31 de enero (P. Pedro José Vela Torres, ECLI:ES:TS:2023:195) viene a unificar criterio con la Sala Social en una cuestión que podría sintetizarse así: cuando uno sufre una enfermedad común que finalmente deriva en invalidez laboral permanente o absoluta, en el contexto de un préstamo hipotecario que obliga a concertar un seguro que cubre dicha invalidez, puede ocurrir que el seguro no esté vigente durante todo el período relevante –desde que se diagnostica la enfermedad hasta que se declara la invalidez–, y surge la duda razonable sobre si la invalidez queda cubierta cuando, a pesar de estar el contrato vigente cuando la enfermedad se diagnosticó, no lo está en la fecha en que la invalidez se declaró oficialmente. La duda es mayor si una cláusula contractual establece que el momento relevante para determinar el siniestro es el de la declaración oficial de la invalidez a cargo de las autoridades competentes. El momento a tener en cuenta dependerá de que nos hallemos ante un supuesto de regla general, o de excepción. La regla será la declaración oficial; la excepción, el momento del diagnóstico irreversible de la enfermedad.

Currency Exchange Rate Formation in Ukraine: Problems and Ways of Optimization
Authors: Kucheriava Karina , Kostrjukova Veronika
Published: February 2024

The conducted analysis proved the presence of quite diverse trends in the foreign exchange market of Ukraine: the national currency is undervalued, the exchange rate is unstable, a significant burden on the financial system as a whole due to the growth of public debt, a high level of dollarization of the economy. That is, on the one hand, there are destructive processes, including those of a chronic nature. On the other hand, the national currency market quickly and easily picks up new opportunities that come to all spheres of economic life, related to digitization and electronic means of trade.

It was revealed that of the key macroeconomic variables that determine the exchange rate: gross domestic product, government debt, gold and foreign exchange reserves, balance of payments, inflation, it is inflation that has the greatest influence on the exchange rate.

Key macroeconomic parameters determining the state of the foreign exchange market can have a destabilizing effect on the foreign exchange market both at a fixed and at a floating exchange rate. It has been proven that the use of any of these regimes in their "pure" form is particularly risky for the economy. An algorithm for making a decision on softening/increasing course flexibility was proposed.
Children's literature: reading strategies and receptivity in early childhood
Authors: Campos Cleide de Araújo , Dacome Eva , Da Silva Luciano Campos
Published: February 2024

To ensure students' mastery of reading and writing constitutes one of the biggest challenges currently facing Brazilian public schools. Data from the Progress in International Reading Literacy Study (Pirls, 2021) estimate that around 40% of Brazilian students in the 4th year of elementary school do not master basic reading skills. Despite the complex nature of the theme, when specifically dealing with young children, literary books play a very relevant role in this process, since research indicates that they constitute a kind of gateway to the world of literature and reading. In this sense, the present article presents the results of an action investigation that aimed to analyze the reception of children's literature books for preschoolers in the age range of 4 to 5 years old, from a preschool, in the city of Presidente Prudente/SP. For the development of the research, we provide children with high-quality literature books – awarded by the Jabuti Prize, which is the most prestigious literary award in Brazil. Group organization was utilized to have a bigger “control” of children's speech and press conferences with the purpose of understanding what criteria the children use when choosing the books. Reading circles were utilized as a methodology to initiate a dialogue within the group and the sharing of impressions about the chosen books. Three elements emerged as central in the choice of books by the children: the cover as the most decisive element, the illustrations and the connections that they made between the book, its characters and the pre-existing knowledge they already had. The work demonstrates that it is necessary to provide opportunities in schools for practices that involve children more, that encourage them to choose what they want to read.

Environmental education has been discussed worldwide throughout society, therefore an increase in actions that promote environmental awareness is essential and the need for the formation of critical, collective and sustainable thinking is emerging. Based on municipal, state and federal laws, the National Curricular Parameters and the National Common Curricular Base report that good academic performance would be of no use apart from the perception of the impact of individual and collective human actions on the environment. However, society has been facing challenges in the continued training of teachers, and developing tools that support the work of these professionals, including those in the Science area, through interdisciplinarity in the initial years, becomes essential. This article reinforces the need to provide such programs, which aim to develop methodological practices that seek lesson plans focused on environmental themes. The research was based on the challenges that teachers face when they propose to develop environments in their classrooms that are favorable to promoting social contexts. In addition to investigating what characteristics are necessary for the development of activities that support collaborative work, allowing the teacher to develop a role as a mediator and not just a transmitter of knowledge.
Art, Eros, and Liberation: Aesthetic Education between Pragmatism and Critical Theory
Authors: Shusterman Richard
Published: February 2024

After showing how pragmatist aesthetics and Marcuse's critical theory affirm aesthetic education as key to transforming society toward greater freedom, equality, pleasure, and fulfillment, I compare the ways these two approaches differently perceive the scope and role of aesthetics in such transformation. Whereas Marcuse identifies the aesthetic dimension with the realm of high art, pragmatism understands this dimension far more broadly to include the popular arts and somaesthetic arts of living. Because Marcuse identifies art's critical function through its oppositional transcendence and autonomy from ordinary reality and practical life, he insists that aesthetics cannot directly contribute to transformative praxis in the real world but can operate only indirectly by transforming our sensibilities. Pragmatist aesthetics, particularly though somaesthetics, resolves the dilemma in Marcuse's aesthetics of liberation by bridging the alleged gap between aesthetics and praxis by reeducating our sensibilities in a more direct, practical, embodied way. The article further exemplifies the overlaps and differences between Marcuse's critical theory and pragmatist somaesthetics by focusing on erotic experience, which is essential to Marcuse's liberational program and increasingly present in somaesthetics’ concern with aesthetic reeducation of our senses and sensibilities.
Joanna Baillie's Theory of Tragedy
Authors: Stone Alison
Published: February 2024

Joanna Baillie (1762–1851) came to fame in 1798 with the first volume of her Plays on the Passions, which included her theoretical account of drama, including tragedy. This article reconstructs Baillie's theory of tragedy and shows how the theory informs the design of the Plays on the Passions. For Baillie, all human beings have powerful and dangerous passions that we need to learn to regulate. Tragedy can help with this and can serve an educative purpose by presenting us with narratives in which the protagonists repeatedly fail to check the growth of a particular passion, such as jealousy or hatred. We witness this passion gain more and more hold over the character's mind until they are destroyed. This offers a warning and motivates us to watch out for the growth of our own passions and keep them in check. Baillie's theory of tragedy is original and combines a moral orientation, a voluntarist belief in free will, and optimism about the human condition. For her, the sufferings undergone by tragic characters could have been avoided had the characters made better choices. Thus the message of tragedy is not that suffering is inescapable but that suffering can be minimized if we cultivate self-knowledge and emotional self-control.
“The Leaves of Our Flag Surrounding the World”: Barbara B. Smith and the Sovereign Voices of a Pacific Trust Territory, 1958–1964
Authors: Diettrich Brian
Published: February 2024

This article explores the songs and dances recorded by Barbara B. Smith in the United Nations Trust Territory of the Pacific Islands, the former US-administered region of Micronesia. The article examines Smith's collaborations with Micronesians in Hawai‘i in the late 1950s and early 1960 as well as her 1963–1964 recording project undertaken across the Trust Territory. In exploring Micronesian voices within the political machinations of the time, the article investigates the entanglement of ethnomusicology within the American colonial administration of the Pacific. With the 1963–1964 recordings as a window into this period, I listen for Indigenous autonomy that sounds out from these historical reproductions. I contend that the broader contribution of 1960s ethnomusicology in Micronesia lies in the sonic chronicle of sovereign voices, in which communities sang together and past American colonial interventions in the Pacific.
Transgression, Struggle, and Scandal
Authors: Müller Anna
Published: February 2024

This article analyzes the lives of a handful of women, who, after years of involvement in various military conflicts (from World War I to World War II), were sentenced to long prison sentences. Particularly, it explores the lives of Anna Neuman, Irena Tomalakwa, Elżbieta Zawacka, and Emilia Malessa from the perspective of the concept “postawa” which most of them acquired in the early years of their life while soldiering (postawa as a concept related to discipline). They understood it as a stand that they would take throughout their entire life. Hence, postawa was more than a social role. It was an attitude, something that they had to achieve throughout their lives, finally also something that guaranteed continuity in their lives. Their imprisonment fit the definition of postawa well and provided them with a chance to define their actions not as heroic acts of Polish patriots, but rather as an attitude to which they were socialized. Through the biographic history of these women, the Polish history of gender can be seen as dynamic (as dynamic as their postawa allowed them to be). In that sense, postawa may be treated almost as a quintessential transgression, which, depending on the situation, can be seen as a phenomenon that helps them cross many boundaries or adapt to circumstances. Paradoxically, it helps them define their space outside of narrowly defined terms of patriotism, heroism, or martyrology, but ultimately giving them a voice as Polish patriots.

Published: February 2024

Out of four major structural changes affecting the US economy – namely a rising share of skilled workers, skill-biased technological change, decreasing progressiveness of taxation and productivity slowdown – we show that the decline in productivity growth not only is the main driver of the widening wealth disparities observed in the United States of America over the past few decades, but is also the only mechanism that can explain inequalities both within and between skill groups.
