Plot composition of Abyisky epic tradition
Authors: Илларионова Т.В.
Published: October 2022

Статья посвящена анализу сюжетосложения абыйской эпической традиции олонхо. Для понимания особенностей поэтики эпоса важное значение имеет рассмотрение характерных признаков сюжетосложения. С целью выяснения сюжетно-композиционной природы абыйской эпической традиции проанализированы тексты вариантов олонхо «Эр Соготох» в исполнении олонхосутов Г. Ф. Никулина и Н. В. Слепцова. Эр Соготох – популярный герой у якутских сказителей, которые из поколения в поколение создавали различные варианты об одиноком богатыре, родоначальнике племени ураангхай саха. Сюжетная структура олонхо состоит из экспозиции, завязки, развитие действия, развязки. Абыйская эпическая традиция относится к северной группе якутского героического эпоса, для которой характерны небольшой объем, сильное влияние сказки, слабая этническая идентификация. Олонхо, записанное со слов Н. В. Слепцова, создано под сильным влиянием мифа или сказки северных народов. Олонхо Г. Ф. Никулина имеет характерные особенности, присущие эпической традиции северных якутов, больше в лексике, нежели в сюжетно-образной системе, но жанровые признаки олонхо этого сказителя остаются преимущественно в рамках общеякутской эпической традиции. Рассмотренные тексты олонхо о богатыре Эр Соготохе имеют своеобразный, только им присущий сюжет. Несмотря на идейно-тематическую общность вариантов, каждый из них сугубо индивидуален и отражает особенности той среды, в которой в процессе бытования развивалось повествовательное ядро, вобравшее в себя все сказительские традиции.

This article analyzes plot composition of Abyisky epic tradition. In order to understand the features of poetics of the epic it is necessary to consider the characteristic features of plot. With the aim of clarifying the nature of plot composition of Abyisky epic tradition there were analyzed such olonkho texts as "Er Sogotokh" options by olonkhosuts G.F. Nikulin and N.V. Sleptsova. Air Sogotokh that is a popular character in the Yakut storytellers, who for generations have created different variants of a lone hero whose ancestor tribe urannghay Saha. Subject of olonkho structure consists of exposure, ties, development of action, denouement. Abyisky epic tradition belongs to the northern group of the Yakut heroic epos which is characterized by small volume, strong influence of fairy tales and weak ethnic identity. Olonkho recorded with words of N.V. Sleptsova was created under the strong influence of the myth or fairy tales of northern peoples. Olonkho by 0.G.F Nikulin has the characteristics of an epic tradition of the northern Yakut people with more vocabulary than in the plot and imagery, but this genre feature of olonkho a storyteller remains mostly within Yakut epic tradition. Examination of the olonkho hero Er Sogotokh has peculiar plot that is typical of only them. In spite of the ideological and thematic common variants each of them is individual and reflects the characteristics of the environment in which the existence in the process of developing a narrative core, incorporate all tale tradition.
Некоторые особенности перевода эпоса: английские переводы Армянского национального эпоса «Давид Сасунский»
Authors: Hambardzumyan H.A.
Published: October 2022

Translation of folklore and in particular the epic, is related with some challenges such as translation of words that incorporate and convey the outline and national identity of epic narrative. So, how do we translate an epic narrative from one language to another? Beyond the translation of words, the interpreter needs to transmit the cultural and social-historical realities of a particular culture to another. Often translators resort to footnotes, however the extensive usage of footnotes can be exhaustive and make the text difficult to read.On the other hand, if all the words are translated via the literal layer of the vocabulary, the epic becomes stripped off its national identity, thus becoming a mere retelling of well-known mythological and epic motives.These problems on different scales are seen in Russian and English translations of the epic “David of Sassoun”. The Armenian national epic has several English translations – “David of Sassoun”: The Armenian Epic in Four Cycles” by Artin Shalian (1964), “Daredevils of Sassoun” by Leon Surmelian (1964) and “The Saga of Sassoun” by Mischa Kudian (1970) etc.Each translation addresses and solves the question of translation of epic in comparative ways. This article focuses primarily on Artin Shalyan's and Leon Surmelian's translations, while dealing with other translations in deriving argument and analysis.

Перевод фольклора и, в частности эпоса, связан с некоторыми трудностями. Например, проблематичен перевод слов-реалий, которые воплощают и передают национальную идентичность эпического повествования. Помимо перевода слов, переводчик должен передать культурные и социально-исторические реалии той или иной культуры. Часто переводчики опираются на сноски, но многочисленные сноски затрудняют прочтение текста.С другой стороны, если все слова будут переводиться, эпос потеряет свою национальную идентичность, и станет, лишь пересказом известных мифологических и эпических мотивов. Эти проблемы, в той или иной степени можно наблюдать в русских и английских переводах эпоса «Давид Сасунский».Армянский национальный эпос имеет несколько переводов на английский язык- “David of Sassoun: The Armeninan Epic in Four Cycles” Артина Шаляна (1964), “Daredevils of Sassoun” Леона Сурмеляна (1964) и “The Saga of Sassoun” Миши Кудияна (1970) и т. д. Каждый перевод по-своему решает эти проблемы. В данной статье в основном анализируются переводы Артина Шаляна и Леона Сурмеляна, но уделяется внимание и на другие переводы.

Статья обсуждает проблему изучения взаимосвязей фольклорных традиций якутов тунгусов (эвенков и эвенов). Представленная проблема исключительно важна для двух задач исследователей. Это, во-первых, происхождение тунгусского эпоса – является ли он продуктом независимого развития тунгусского фольклора или же тунгусский эпос сложился под прямым воздействием образцов якутского героического эпоса олонхо или, возможно, при влиянии какой-то иной эпической традиции, которая была близка к тюркской и монгольской.

AbstractThis study aims to determine the expression of attitudes on the Mild Report news site Tirto.id. Stance expressions are the author's feelings and personal thoughts. This research uses the corpus linguistics method. The analysis of the corpus and computer data was carried out using the AntConc software. The data were analyzed using Hyland's stance expressions analysis framework. Namely, it consists of four elements, namely hedges, boosters, attitude markers, and self-mentions. The results showed that the attitude markers element was 24%, the boosters were 31%, the hedges element was 41%, and self mentions was 4%. This finding shows that the stance expressions of Hedges and Booster are used by the editorial team of Tirto.id respectively. Hedges points out that the author's decision to avoid a full commitment to the reinforcing statement expresses certainty about the proposition he makes in the text. Based on the research, it can be said that the writers of the Mild Report news on the Tirto.id website tend to be careful, such as by avoiding more risk, on the other hand the author also shows his confidence in the data based on the prepositions built by the author on the news text that is presented. This research can be developed further by adding the amount of data in the corpus, namely Mild Report news articles on the Tirto.id site. Stance expression analysis can also be applied to other texts, such as discourses or academic works to determine the author's attitude by utilizing the linguistic features of the text. Keywords: Stance expressions, Typical stance items, Corpus Linguistic, News Sites, Tirto.id.

Aim. To evaluate the efficacy, safety and effect on the prognosis of cardiac contractility modulation (CCM) in patients with chronic heart failure (CHF) with reduced left ventricular ejection fraction and atrial fibrillation compared with the group of only optimal drug therapy (ODT) of the 12-month follow-up.
Materials and methods. Patients (n=200) were sequentially included in two groups: group 1 patients with CHF who are on ODT in combination with implanted CCM devices (n=100), group 2 comparison patients with CHF who receive only ODT (n=100). Initially and after 12 months, 12-channel electrocardiography (ECG), transthoracic echocardiography, daily ECG-monitoring, determination of the level of NT-proBNP, a six-minute walk test and an assessment of the quality of life according to the Minnesota Questionnaire were performed.
Results. In the CCM therapy group, a significant clinical improvement was revealed, which was expressed in the form of a decrease in functional class CHF by NYHA (New York Heart Association), an increase in the distance of a six-minute walk test and an improvement in the quality of life according to Minnesota Questionnaire, as well as an improvement in left ventricle contractile function compared to the ODT group. The absence of a proarrhythmogenic effect of the CCM was shown. There was a significant decrease in the frequency of the readmission due to CHF and the probability of achieving the combined endpoint in the CCM therapy group compared with only ODT.
Conclusion. The use of CCM in patients with CHF and atrial fibrillation is an effective and safe method of therapy that leads to the development of reverse remodeling of the myocardium, improves the clinical status of patients and reduces the frequency of readmission due to decompensation of CHF.

Aim. To determine the frequency, distribution and characteristics of ectopic obesity in patients without manifested cardiovascular disease.
Materials and methods. We examined 320 patients without manifested cardiovascular disease (average age 63.813.9 years), 38 of them without cardiovascular risk factors (healthy referent group). Anthropometric indicators were measured, body mass index (BMI) was calculated. Degree, type of obesity, lipid profile were evaluated. All patients underwent multi-detector chest computed tomography in spiral mode on Toshiba Aquilion Prime scanner using standardized protocol. Perivascular adipose tissue (PVAT) and pericardial adipose tissue (PAT) were detected using specialized semi-automatic software Tissue Composition Module QCTPro (Mindways Software, Inc., USA) after scanner calibration with special phantom. PAT and PVAT exceeding the 90th percentile in the healthy referent group were considered as ectopic obesity. Statistical analysis was performed using Statistica 10.0 software (StatSoft Inc., USA).
Results. PAT volume 3.2 cm3 and PVAT volume 0.4 cm3 were criteria for high pericardial and high perivascular fat; 81 (25.2%) patients had ectopic obesity, 85 (26.5%) patients abdominal obesity; 146 (42.9%) people had high pericardial fat, 134 (39.4%) high perivascular fat. The frequency of ectopic obesity in patients with arterial hypertension (AH) was statistically significantly higher compared to persons without AH. Significantly more often ectopic forms of obesity were detected in patients with overweight and obesity. The high pericardial fat and high perivascular fat were found in patients with overweight and normal body weight. When comparing the clinical characteristics of patients with abdominal and ectopic obesity, metabolic parameters, as well as the incidence of hypertension and dyslipidemia, did not differ significantly.
Conclusion. Ectopic obesity can develop outside of global obesity. In addition, this type of obesity is accompanied by metabolic disorders and AH, regardless of the abdominal distribution of adipose tissue.

Aim. To systematize data on the prevalence of the combination of functional dyspepsia (FD) and irritable bowel syndrome (IBS) using the Rome IIIIV Criteria.
Materials and methods. A search in electronic databases MEDLINE/PubMed, EMBASE, and Cochrane was conducted. The depth of search was 17 years (from January 2006 to May 2022). Original publications from peer-reviewed periodicals that applied the Rome IIIIV Criteria for diagnosis of FD and IBS in an adult patient population with detailed descriptive statistics to allow the resulting data to be included in the meta-analysis were selected for final analysis.
Results. The final analysis included 38 studies involving 17,993 patients with FD and 15,883 patients with IBS. In the overall pool of studies using the Rome IIIIV Criteria, the pooled prevalence of FD in patients with IBS was 34.625% (95% confidence interval [CI] 28.15941.390), and the pooled prevalence of IBS in patients with FD was 37.549% (95% [CI] 31.51143.787). A random-effects model was used in the analyses since significant heterogeneity between results was found (p0.0001; I298%). Using the Rome III Criteria, the pooled prevalence of FD in patients with IBS was 31.993% (95% CI 26.13538.150; I2=98.17%), while the prevalence of IBS in patients with FD was 34.694% (95% [CI] 29.31940.273; I2=97,89%). An analysis of papers using the Rome IV Criteria demonstrated that the pooled prevalence of FD in patients with IBS was 42.614% (95% CI 18.58868.675; I2=98.97%), and the prevalence of IBS in patients with FD was 50.444% (95% CI 37.95662.904; I2=94,39%).
Conclusion. This meta-analysis demonstrated that the prevalence of the combination of FD and IBS identified using the Rome IIIIV Criteria is high and is reported in approximately 1 in 3 patients with the functional gastrointestinal disorders concerned. The prevalence of a combination of FD and IBS identified using the Rome IV Criteria is at least 10% higher than that using the Rome III Criteria.

Published: October 2022

Aim. To assess the role of atorvastatin to the frequency of contrast-induced acute kidney injury (CI-AKI) in patients with cardiovascular diseases (CVD) undergoing computed tomography (CT) with intravenous contrast media.
Materials and methods. One hundred patients with CVD undergoing CT with with intravenous contrast media administration were included in prospective observational study (ClinicalTrials.gov ID NCT04666389). Patients were divided into 3 groups 16 (15.8%) patients receiving atorvastatin at a dose of 80 mg 24 hours and 40 mg before the CT and 40 mg after; 33 (32.7%) patients 40 mg before the CT and 40 mg after; 52 (51.5%) people not receiving statin therapy. The primary endpoint was CI-AKI according to KDIGO criteria: the 25% rise (or 0.5 mg/dl) of serum creatinine from baseline assessed 4872 hours after administration of contrast media. There were 51% of men. The average age was 59.7714.4. The most frequent cardiovascular disease was hypertension 86%.
Results. CI-AKI was diagnosed in 4 (3.96%) patients. At the same time, it was not possible to establish statistically significant relationships (p0.05) between risk factors and the development of CI-AKI. Statins can be a successful way to prevent this complication.
Conclusion. Cardiovascular diseases may increase the risk of CI-AKI after computed tomography with intravenous contrast media administration. Therefore, it is recommended to evaluate the serum creatinine concentration in such patients.

Dangshen Codonopsis javanica exhibits invaluable medicinal properties in herbal remedies; however, there has currently not been much specific analysis of the phytochemicals and bioactivities of this plant. The root ethanol extract of C. javanica contains substances such as saponins, phenolic acids, terpenoids, and alkaloids. It displays an antibacterial effect against Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus, and Bacillus cereus with the IC50 values of 150, 100, 150, and 90 μg/mL, respectively. The antioxidant capacity of the root extract was also observed with an IC50 value of 46.8 ± 6.8 μg/mL. Furthermore, the extract exhibits activity on human cancer cell lines HepG2 (IC50 = 83.6 ± 2.7 μg/mL) and MCF-7 (IC50 = 95.3 ± 2.3 μg/mL). Hence, this study provides the basic data for further research on the bioactivities of natural compounds of Dangshen C. javanica for the first time.

Irradiation is known as a handful measure to inhibit potato sprouting, kill harmful bacteria, and increase preservation. The absorbed dose is one of the essential characteristics of the irradiation process. In this study, the depth-dose distributions in potatoes and polymethyl methacrylate were investigated under low-energy X-ray irradiation by using the Fricke dosimeter and Gafchromic film dosimeter. The dose rates required for the rays to penetrate in polymethyl methacrylate were compared with those in potatoes. Polymethyl methacrylate could be used as a phantom in measuring the depth dose delivered in potatoes. The difference in depth-dose distribution in potatoes between one-sided and double-sided irradiation was also investigated. The calculated dose uniformity ratio values are 5.8 and 1.9 for potatoes irradiating one-sided and double-sided.
Magneto-transport properties of monolayer borophene in perpendicular magnetic field: influence of electron-phonon interaction
Authors: Tho Ta T. , Huynh T. Hoa , Nguyen V. Chuong , Luong M. Tuan , Bui Dinh Hoi
Published: October 2022

The magneto-transport properties of a borophene monolayer in a perpendicular magnetic field B are studied via calculating the conductivity tensor and resistance under electron-optical phonon interaction by using the linear response theory. Numerical results are obtained and discussed for some specific parameters. The magnetic field-dependent longitudinal conductivity shows the magneto-phonon resonance effect that describes the transition of electrons between Landau levels by absorbing/emitting an optical phonon. The Hall conductivity increases first and then decreases with the magnetic field strength. Also, the longitudinal resistance increases significantly with increasing temperature, which shows the metal behaviour of the material. Practically, the observed magneto-phonon resonance can be applied to experimentally determine some material parameters, such as the distance between Landau levels and the optical phonon energy.
And yet, it moves: Lobbying Regulation in the Council of Ministers of the European Union
Authors: Schmidt-Meinecke Erik
Published: October 2022

This study aims to explain the commitment of the Council of the European Union to the Inter-Institutional Agreement on a common Transparency Register for interest representatives with the Commission and European Parliament in 2021. To scrutinize this surprising turn in the hitherto transparency-averse position of the Council, this study draws on a set of elite interviews with Council sources and transparency stakeholders. The emerging data are analyzed through a theoretical framework grounded in institutionalist theory, grouped in a strategic, institutional, and ideational dimension. Evidence on a strategic dimension suggests a transparency-averse majority in the Council that explains the overall skepticism of the institution towards advancing lobbying transparency. The institutional dimension reveals the Council as compelled by norm-entrepreneurship and a logic of appropriateness instilled by other institutional actors in the Inter-Institutional Agreement. Lastly, the ideational dimension reveals shifting notions of transparency, as well as effective change agency and knowledge sharing through pro-transparency actors within the Council. The study concludes that, while a merely strategic analysis of institutional change fails to explain reform, a holistic institutionalist perspective, considering different dimensions of institutional change, is well suited to explain the advance of lobbying transparency in the Council. Further research could draw on the tentative findings of this research and attempt a longitudinal assessment of drivers and inhibitors of lobbying transparency in the Council.

The exact definition of an Ultralight Aircraft is still very diverse, especially in the European region. Internationally, there are various Ultralight Aircraft (UL) classes with nationally varying certification regulations. Accordingly, Ultralight Aircraft is used colloquially ore or less comprehensively for Very Light Aircraft or Light-Sport Aircraft. However, they are subject to much stricter certification nd maintenance regulations. This paper aims to compare the current legal situation in the European Union countries, extract the best practices, and propose how a new “AMC & GM” should define the laws and regulations to create the best possible vironment for UL airworthiness. This paper is written based on information and directions published on the websites of the esponsible uthorities of the respective countries, as well as communication with these authorities and first-hand knowledge obtained by conducting numerous interviews with people in the field of UL maintenance. The results indicate how different each country egulates the maintenance and continuing airworthiness of ULs and how important a harmonised regulation would be. It is specially important to have clarity as with larger aircraft and thus also to prevent numerous accidents and hazardous situations in the future.

Published: October 2022

As a result of a tragic accident in Southern Austria, all L-13 “Blanik” sailplanes were grounded. During this accident, the factory structural design failed, even though the plane underwent all mandatory inspections and repairs. The intention of this article is to introduce the possibilities of structural modification of this aircraft, specifically its wing beam and hinge. Already existing modifications are described, as well as new ones with the aim to strengthen its critical parts. Structural modification of the wing hinge and beam, replacement of rivet joints with stronger Hi-Loks and use of different hole angles to ensure a firmer joint and better stress distribution around these holes are covered. Last two beforementioned modifications are described in more detail, a tensile test is carried out and its results are compared to the results of the control samples. In the end, viability and practicability of these modifications are discussed.
Changes in airport infrastructure caused by the historical development of aircraft
Authors:   University of Žilina, Adamík Jozef , Kazda Antonín
Published: October 2022

The airport infrastructure is constantly influenced by the development of aircraft. It has always been, that the aircraft was first designed, and based on its performance parameters and geometrical characteristics, a space for the airport were sought to serve the new aircraft. Even today, we can see the different development of aircraft in different aircraft manufacturers, which determine how the airport infrastructure will change in the future. In the introductory chapters, we analyze several aircraft requirements for airports that have been affected by changes in ground infrastructure and the subsequent development of airports. The main objective of this bachelor thesis is to document the changes in the airport infrastructure caused by the historical development of aircraft. The discussed development of aircraft and reaches out from the beginning of aviation to the end of World War II through the era of jet aircraft to large-scale long-haul aircraft. Based on the creation of a database of aircraft and a description of typical aircraft representatives of the period, an analysis of their parameters and the described impact on selected airports is performed. Three historical international airports were selected for a detailed analysis of airport development. There are two analyzed airports in Europe: Munich Riem together with Munich - Franz Josef Strauß and Amsterdam Schiphol. In the United States, John F Kennedy Airport is chosen near New York City in terms of the highest airline utilization. Until 1951, selected airports were analyzed from historical footage and, after the publication of ICAO Annex 14 Aerodromes, also documented by changes in the regulation. Airports had to adapt to changes in environmental requirements and the introduction of new technologies in the form of more fuel-efficient and smaller commercial aircraft. One of the benefits of the thesis is to emphasize the need to plan airport changes in relation to the needs of aircraft technology in the future. This area includes the planning and modernization of runways (RWY), terminals, aprons and stands. At present, RWY design pays attention to reducing noise in suburban areas, reducing turn-round time at stands by using jetways, the number of taxiways (TWY) connecting the RWY to the airport and operating aircraft with a smaller code letter.

Authors:   University of Žilina, Chynoranský Jakub , Jarošová Miriam
Published: October 2022

The division of meteorology is an integral part of aviation that informs about meteorological phenomena and defines their nature. This article focuses on the types of meteorological conditions with which the aircraft comes into contact during the flight, with a closer focus on the take-off and landing phases of the aircraft. The topic of meteorological conditions and their effects was chosen due to the enormous importance of this segment of aviation for the safety and operation of air traffic. The paper has a theoretical character and approaches the connection between individual meteorological conditions and their effect on the behavior of the aircraft. For air safety, a proper interpretation and subsequent adaptation to the corresponding weather events and deviations from standard conditions is essential. The aim of the publication is to define the basic meteorological conditions, weather phenomena and to underline their considerable importance for air traffic. The final part is devoted to the analysis of air accidents during takeoff and landing, which were caused by adverse weather conditions and their underestimation.

Authors:   University of Žilina, Remiaš Matej , Pecho Pavol
Published: October 2022

In the early days of aviation, wind tunnels were developed to investigate whether an aircraft is capable of flying, and how capable it was of doing so.They are mainly used as a part of research of aerodynamic forces applied to a model of an aircraft or its parts. There are several methods of measuring the airflow inside a wind tunnel, however this manuscript is concerned with implementation of Particle Image Velocimetry (PIV), especially the software part, in the conditions of the wind tunnel of the Department of Air Transport. The functions of the software were investigated on the basis of a simple experiment. The poppy seeds were blown on white paper and the images were captured by the camera in slow motion as it moved from side to side and then the images were processed and analyzed. The amount of poppy seeds used varied.The results showed successful use of PIV software and it’s application directly in the wind tunnel of the Department of Aviation for research of the effects of aerodynamic forces in aviation, but also in other areas.
Artificial intelligence and its use in air transport
Authors:   University of Žilina, Bendík Dávid , Novák Andrej
Published: October 2022

In recent years, modern technologies have found large applications in sectors such as engineering, healthcare, information technology, robotics, and so forth. One important field in the use of such modern technologies is the field of air transport, where the main objective of using these technologies is to facilitate work for people, make individual tasks more efficient and faster, or reduce the risks associated with human error. In this paper, we will look at artificial intelligence and its use in aviation. Despite the rapid pace of improvement, artificial intelligence is still finding its way to reach its full potential. The history of artificial intelligence dates back to ancient times when many philosophers wondered whether a machine could think. The answer is found in the second half of the 20th century, when, besides theoretical knowledge, we can also observe the first intelligent machines. There is no clear and single correct definition for artificial intelligence, so the subject of the next section is to define artificial intelligence from different sources. The following section details the difference between deep learning and machine learning, comparing their main differences and applications in aviation. The analysis of the current state of application of artificial intelligence in aviation represents the core part of this paper. The emphasis in the analysis is put mainly on applications in the field of airports, air traffic management and safety. In each of these areas, the benefits of using AI are evaluated based on already established AI-enabled technologies. Finally, by analysing the sources available and those applied in our work with the use of a mathematical model, we assess how important the role artificial intelligence currently plays in air transport.

This aim of the paper is based on a theoretical analysis of possibilities of reducing fuel consumption, emissions and noise during aircraft take-off, taxi and turn-over procedure. In the very beginning, author defines the basic terms of airport infrastructure and defines types of taxiways based on their constructional solution and physical characteristic. Taxiways are not given to the aircrafts as efficient as possible on many airports. To point out the possibility of reducing fuel consumption and emissions production from different taxiway route, author decided to analyse taxiway and runway infrastructure of Vienna-Schwechat Airport (IATA: VIE) and made runway analysis of Airbus A320-200. Another option how to reduce mentioned attributes and increase the quality of environment is single engine taxi (SET) procedure. Author analysed advantages and disadvantages of SET and established possible communication between aircraft crew and air traffic control officer. Push-back tractors produce not negligible amount of pollutants too. The solution is to operate zero emission push-back tractors powered by electric engine or implement innovative system WheelTug into the nose landing gear. These solutions bring many advantages for surrounding environment and reduce airport noise too. Last not but least, author describes advantages and possibilities of use of Fixed Electrical Ground Power instead of APU or GPU during turn-over procedure

Factores pedagógico, familiar y social, influyentes en la conciencia ambiental en estudiantes de la institución educativa el mirador
Authors: Valencia Pérez Sandra Patricia
Published: October 2022

La articulación entre la educación formal y ambiental, se concibe como la solución para intentar detener la amenaza ambiental. No obstante, se evidencian fallas en el fortalecimiento de la conciencia ambiental desde el aula. Por ello, el presente artículo científico, resultado de la investigación cualitativa: Factores pedagógico, familiar y social, que influyen en la toma de conciencia ambiental en la Institución Educativa El Mirador, en el Municipio de Popayán, cuyo objetivo fue describir qué factores culturales relacionados con el entorno pedagógico, familiar y social pueden influir en la toma de conciencia ambiental, en los estudiantes de la Institución Educativa Pública El Mirador (Popayán, Cauca). Para lo cual, se considerarán el origen, los componentes, los aportes investigativos de otros autores, la metodología, la discusión y las conclusiones. Los cuales son necesarios conocer, para establecer estrategias que vinculen el aula y la educación ambiental.Como respuesta al diseño de esta investigación-acción, los estudiantes fortalecieron la educación ambiental al crear una revista, a través del Aprendizaje Basado en Problemas. Se concluye que, los factores que influyen en la toma de conciencia ambiental de los educandos, en la categoría pedagógica es la falta de articulación del Proyecto Educativo Institucional, con la educación ambiental, en tal sentido, la malla curricular y los Derechos Básicos de Aprendizaje, contemplan contenidos específicos de tipo naturalista y el Proyecto Ambiental Escolar no se ha ejecutado; en la categoría familiar, es la carencia  de formación en valores y hábitos ambientales y en la categoría social, la ausencia de patrones de conducta motivadas por la organización de actividades ecológicas en la comunidad, por parte de los líderes comunales; en el círculo de amistad, el acto de compartir actitudes nocivas para el medio ambiente. Todos estos factores están directamente relacionados con la falta de educación ambiental. Por ello, la propuesta educativa, al fomentar el conocimiento y, la práctica de la educación  ambiental contribuyó a incrementar el grado de participación del estudiante en el hecho ambiental mediante actitudes comportamentales respetuosas, conducentes al fin último de la educación ambiental: la práctica sostenible de la vida.

Authors: Hernández Suárez John Alexander , Salazar López Ángela María , Ruiz-Ochoa Mauricio Andrés
Published: October 2022

Objetivo. Estimar los datos faltantes de la precipitación media mensual en el departamento de Casanare.

Metodología. Se revisó la información de estaciones climatológicas de precipitación media mensual descargadas del Instituto de Hidrología, Meteorología y Estudios Ambientales (IDEAM), se calculó el ciclo estacional, y en caso de existir datos faltantes estos se completaron mediante el método estadístico de variabilidad climática estacional.

Resultados. De todas las estaciones climatológicas inventariadas, solo el 43 % se encuentra en funcionamiento, pero al revisar los datos se encontraron datos faltantes, así, los valores más bajos (altos) se presentaron en los municipios de Chámeza (Aguazul), correspondientes a 0.42% (40.14%), calculados de 1 (3) estaciones climatológicas. Por lo que, al aplicar el método estadístico de variabilidad climática estacional para completar los datos faltantes, se obtuvieron series de tiempo que no alteraban la dinámica natural de la variable analizada.

Limitaciones. Las limitaciones del trabajo estuvieron dadas por el acceso a la información del IDEAM.

Originalidad. En cuanto a la originalidad el trabajo no hace un mayor aporte, pero si responde a una temática trabajada endiferentes partes del país, pero que para el departamento de Casanare responde a información escasa.

Conclusión. Se concluye que para los municipios del departamento de Casanare se deberían tener todas sus estacionesen estado activo, y en lo posible con el menor porcentaje de datos faltantes, para que así se puedan realizar estudios másasertivos en cuanto a la variabilidad natural del clima.
Sovereign Credit Rating and Yield to Maturity of Government Eurobonds. (c2022)
Authors:   ,   Lebanese American University, Torbey Jose
Published: October 2022

Since 2019, Lebanon has been going through one of the worse financial, economic and social crises in centuries. The country is facing very high levels of poverty and unemployment, the local currency has lost more than 90% of its value, and, above all, people can no longer withdraw the money they have placed in Lebanese banks. The country, which is highly indebted, declared bankruptcy after the government announced that the state would not be honoring the payments on the Eurobonds it issued. Looking at data since 2016, it was shown that a change in sovereign credit rating opposingly correlates with the yields to maturity of the government-issued Eurobonds in the case of Lebanon. Moreover, this study argues that both the GDP growth rate and the Inflation may positively moderate the previous relationship by strengthening the negative relationship between the sovereign credit rating and the yields to maturity of the Eurobonds.
The Effect of Perceived Organizational Support during COVID-19 on Innovative Workforce Behavior. The Role of Workforce Reskilling and Top Management Support. (c2021)
Authors:   ,   Lebanese American University, Aoun-Noujaim Grace
Published: October 2022

The coronavirus outbreak is affecting hundreds of millions of people around the world. Decision makers face tremendous hurdles with people confined to their homes and economies effectively shutting down. The pandemic has caused changes in working schedules and overall worker prosperity. As a result, organizational support has become critical in assisting employees in adjusting to the “new normal” and contributing to the transition process. Human resource management plays an important role in improving employees' quality of life and reducing the health risks associated with their jobs. Constant training during the pandemic became necessary to accomplish adequate reskilling of staff. Although the extent research on the relationship between perceived organizational support and innovative workforce behavior is extensive, there is a gap in the literature in assessing this relationship while taking into consideration the role of workforce reskilling and top management support. The aim of this thesis is to develop and test a holistic conceptual model that depicts the relationships among workforce reskilling, top management support, organizational support during COVID-19, and innovative workforce behavior. In particular, the role of workforce reskilling plays in explaining the relationship between organizational support during COVID-19 and innovative workforce behavior, and the role top management support plays in enhancing this relationship are investigated. The conceptual model is empirically tested using an online questionnaire sent to employees working in Lebanon and the region. The findings provided evidence supporting the proposed relationships.
