ASSESSMENT OF FLOOD DEVELOPMENT DUE TO THE DESTRUCTION OF DAMS
Authors: Kril Tetiana
Published: March 2023

Since the beginning of hostilities in the Ukraine territory, there have been several cases of detonation of dams on reservoirs. These events affected the surrounding areas, leading to a flood of different degrees. One of the significant cases occurred on the dam covering the Irpin river, close to Kyiv. It was built during the Kyiv Reservoir filling to prevent the flooding of the river valley and serves as a bridge. After a part of the dam was broken, water from the Reservoir began to fill the Irpin river. The flood threatened Demidiv and settlements further along the river valley. The study aims to determine the areas and volumes affected by water from the Reservoir, estimated material losses and the development of dangerous engineering and geological processes using remote sensing data. The method of identifying water bodies and, in general, bodies with a certain degree of hydration (vegetation, rivers, lakes, moistened soils) based on many spectral images consists of the calculation of Normalized Differential Water Indices. The water index was calculated from the green and near-infrared bands of space images from the Landsat 8-9 mission in the period from February 24 to April 30. The volume of water that formed the flood was calculated. For this, a digital terrain model was built based on the ALOS PALSAR space image, where each pixel of GeoTiff contains the height value. The flooded area is 16.5 square kilometres per month. The deposits of the first and second on the floodplain terraces, composed of uneven-grained sands, were flooded. The development of engineering-geological processes and the engineering protection of settlements are analyzed. The most common threats are flooding and swamping, erosional and gravitational processes are not observed.

The theoretical model of perfect business competition is designed based on five assumptions: atomicity of demand and supply, homogeneity of the product, free entry/exit in/from a branch of activity or on/from the market, market transparency, (with the fundamental assumption of the individual's rationality) and perfect mobility of production factors [1], [2]. The factorial analysis carried out for an economic agent from an Eastern European country highlighted the fact that the production function is homogeneous. For taking or not the decision to launch new products on the market with strict use in a dynamic environment (e.g. breaking strength greater than 200 daN/5cm), salinity of 0.5 - 20�, with specific density, taking into account the existence of decision alternatives, uncontrollable future events (economic conditions, geopolitical instability, etc.). The numerical application, carried out, evidenced that the economic agent will launch the product on the market, regardless of whether or not there are competitors on the market, but 1 m2 of composite material will be sold at an average price, in the situation where there is competition on the market. In the situation where there is no competition, will sell 1m2 at the highest estimated production price [3].
EVALUATION OF CRITICAL POINTS AND THEIR CONTRIBUTING AREAS ACCORDING TO CURRENT LAND USE AS MAIN INPUT FOR DESIGN AND EVALUATION OF THE EFFECTIVENESS OF NATURE-FRIENDLY MEASURES
Authors: Plevkova Miroslava
Published: March 2023

Hydrological extremes (drought-flood) are a phenomenon that is occurring more and more frequently because of climate change. The human-altered landscape cannot sufficiently withstand these extreme phenomena. For this reason, society feels pressure on the design, and assessment, but especially the implementation of adaptation and mitigation measures in the landscape. For best-designed measures, it is crucial to determine where the given problem arises and what are the possibilities of its solution with subsequent quantification of effectiveness. In the Czech Republic, this problem is solved in the long term by processing flood maps and determining flood areas. In 2009, a methodology was created for the identification of places that are potentially threatened by flash floods [1]. In the interest area of the Dyje basin, 1356 critical points were determined by this methodology. The work's main goal was to evaluate these points and their contributing areas based on current data, and the summary and evaluation of the accessible data that will be used for proposals for measures. All analyses were made by using geographic information systems. It was specifically about evaluating the percentage representation of arable land, as one of the main criteria for determining the critical point. It was found that in almost 42 % of the critical points (or in their contributing areas) there was a decrease in arable land by more than 10 %. Furthermore, the occurrence of recorded erosion events was addressed. According to information from the Research Institute for Soil and Water Conservation, there were 622 erosion events in the Dyje basin area, and 43 % were in catchment areas of critical points. One of the crucial topics that are currently resonating in society in terms of proposals for measures in the landscape is drainage areas. According to vectorized documents from the Agricultural Water Management Company, these areas are in 57 % of the collection areas of critical points. The evaluation will further enter a multi-criteria analysis for the selection of a priority area, as the Dyje basin is quite extensive for more detailed analyses. Subsequently, protective measures close to nature will be designed and evaluated in the priority area using mathematical modelling.
GEOCHEMICAL CHARACTERIZATION OF ORGANIC-RICH LACUSTRINE SEDIMENTS FROM ROSULET, ROSU AND PUIU LAKES, DANUBE DELTA, ROMANIA

Published: March 2023

Several geochemical analyses (bulk parameters, particle size, loss on ignition, major, minor and trace elements) were performed on 51 recent sediment samples collected in May 2022 from Rosulet, Rosu and Puiu lakes which are located in the fluvio-marine delta plain of the Danube Delta, Romania. The aim of this study was to decipher the potential origin of anthropogenic and/or natural sources, weathering, sedimentary processes and the local geochemical fingerprint on the distribution of specific chemical elements in lacustrine sediments. The resulting compositional dataset showed an interesting spatial variation of the investigated variables. Loss on ignition identified higher concentration of sedimentary organic matter (TOM%) suggesting the autochthonous input derived largely from macro-and micro-phytoplankton, remnants of the biota etc. Similarly, the higher concentrations of total carbonates (CAR%) are attributed to autochthonous input being associated with biogenic debris. Generally, the particle size results exhibited that the lacustrine samples belong to the textural categories as sandy silt and silt. The spatial distribution of major (CaCO3%, TOC%, Fe2O3%), minor (MnO%) and trace components (Rb, Sr, Zr mg/kg) is considerably influenced by the sediment catchment basin lithology. Technophilic elements results (As, Cr, Cu, Hg, Ni, Pb, V and Zn) were related to the maximum allowable limits (MAL) and/or to the natural background reference values stipulated by the national environmental references. Based on the results of contamination analysis, most of the heavy metals (Cr, Cu Pb and Zn) were below the limits (MAL), implying that they have insignificant environmental risk. Instead, the obtained results implied a relatively high concentration of As, Hg, Ni and V, which exceed the corresponding reference standards in some samples. This may be attributed to the presence of allochthonous elevated concentrations of metals transported by the main and secondary hydrographic network waterways up to the interdistributary depressions, or as a consequence of autochthonous input, reflecting a local signature of the natural geochemical fingerprint. The findings from this study provide useful information for the environmental risk assessment relating to the current environmental conditions within deltaic ecosystems as an integral part of the Danube Delta Biosphere Reserve, one of the world�s most important and vulnerable areas in terms of pollution, Danube River water levels, extreme weather conditions (floods and droughts), and other factors exacerbated by the climate change.

Published: March 2023

Estradiol, also designed as 17- ? -estradiol, belongs to the pharmaceutical class of steroid estrogens and was included in the �Watch List� since 2013 the Directive 2013/39/EU due to its potential risk to human health and environment. The low removal efficiency of estrogens by the conventional wastewater treatment plants, becomes a major source of their release into different aquatic matrices. This work presents the optimization of an analytical methodology based on solid phase extraction and high-performance liquid chromatography using the response surface methodology to detect and quantify 17-?- Estradiol in wastewater treatment plant effluents. From a set of 10 studied solvent/mixture compositions, pure methanol was selected as the better choice to use as mobile phase composition for liquid chromatography. The solid phase extraction step was optimized using a three-level Box-Behnken experimental design with sample volume, sample pH, adsorbent drying time and solvent composition in the washing step, as the four factors to be studied. The sample volume of 500 mL, a sample pH value adjusted to a value of 2, an adsorbent drying time of 60 min and the use of 10% of methanol in the adsorbent washing step were the obtained optimized conditions. The pH value was concluded to be the more significant parameter for average recuperations of estradiol higher than 80%. The method validation was performed by monitoring 17-?-estradiol in real wastewater treatment plant samples, collected from raw affluent, secondary treatment and treated effluent. The methodology was tested successfully, and estradiol was quantified in all the three studied samples.
RESERVOIR SEDIMENTATION EFFECT ON WATER SUPPLY UNDER CONDITIONS OF CLIMATE CHANGE
Authors: Bednar Martin , Marton Daniel
Published: March 2023

Reservoir sedimentation is the gradual accumulation of the incoming sediment load from a river. With the increasing inappropriate usage of agricultural land, the amount of sediment is becoming larger due to erosion. This undesired outcome is supported by changing hydrological and climatological conditions within a river basin. Climate change has wide effects on all processes within the water cycle, which directly affects water resources. Water management in the future must be adapted for oncoming extremes accompanying climate change, such as floods or droughts. Therefore, sediment accumulation is a serious problem with severe consequences for water management, flood control and the production of energy. Unfortunately, sedimentation will be always a problem until anthropogenic activities (which are accompanied by topsoil erosion), such as overgrazing or deforestation, are strictly controlled. We analysed the effect of sedimentation on two reservoirs � Vranov and Znojmo � which are in the Czech Republic, near the border with Austria. The new measurement of each reservoir�s bottom was carried out in 2021 and 2022. Using ArcMap software, two digital models of the reservoir bottoms were developed. One model used the original measured data, and the other the new data from 2021. The storage-area-elevation curves were evaluated for both models and then compared. There was a storage loss of 7.7% for reservoir Vranov and 16.2% for reservoir Znojmo for the maximum operating water level. Since both reservoirs are water supply reservoirs and in cascade, their management has a large impact on the whole system of reservoirs. This impact was tested using a reservoir system model created in HEC-ResSim software, where the change in long-term mean streamflow was observed. The effect of reservoir storage loss was also analysed under conditions of climate change, where three different RCP scenarios were used to simulate climate change during the period from 2021 to 2060. Storage loss for both reservoirs had added an average 1.95% decrease in long-term mean streamflow to another decrease of 28.0% caused by climate change.

Published: March 2023

When considering the (sub)region of Central and Eastern Europe (CEE) and its position in the global economy in relative terms represented by trade openness, the European Union (EU) members from the CEE (sub)region tend to match or even exceed the EU average and EU membership underlines their potential. Recently, environmental concerns have become prominent in international trade and in the framework of its external relations the EU seeks to boost its ambition of a global player. Our paper is oriented on the economic diplomacy and environmental diplomacy theme � in terms of EU competences represented by �commercial diplomacy�, �trade diplomacy� and the �Green Deal diplomacy�. To promote more sustainable developments, the EU�s European Green Deal (2019) emphasises the Comprehensive Strategy of the EU with Africa and this is why the aim of our paper was to assess the EU�s interests in transregional sense by applying the Pareto-optimal scenario/the Nash equilibrium to the qualitative hypothesis formulated: �Geostrategic interests of China and of the postBrexit EU in the process of shaping a new EU strategy towards Africa are partly of a rival and partly of a complementary nature�. When documenting quantitative & qualitative sustainable development trends in the context of international spillovers and relevance of both transregional complementarity & rivalry between the EU and PRC/China, our paper addressed the United Nations 2030 Agenda as well as the African Union Agenda 2063.

Published: March 2023

The territory of Ukraine is characterized by the occurrence of a large number of wildfires, mainly in mixed and coniferous forest ecosystems of Polissia, Forest-Steppe and Ukrainian Carpathians. The frequency of occurrence and destructive consequences of natural fires in forest ecosystems require the adoption of prompt measures aimed at their prevention, localization and liquidation.
Monitoring plays the main role in the process of preventing wildfires, since observation, collection, analysis and assessment of qualitative and quantitative parameters of the state of forest ecosystems, dangerous processes occurring in them, as well as potential sources of wildfires will allow developing and implementing measures aimed at preserving biodiversity and gene pool of forest biocenoses, reduction of material losses, localization of zones of natural fires, termination of the action of dangerous factors characteristic of them. The main field of practical application of monitoring is the information service of the authorities in the conditions of wildfires.
Information monitoring system (IMS) is a distributed system of continuous observations, laboratory and other control for assessing the state of forest ecosystems, as well as dangerous processes occurring in them that can lead to a threat or the occurrence of fires, as well as timely identification of trends in their change.
The main tasks of the IMS are: assessment of the impact of fires, recreation, pests and diseases on forest ecosystems, identification of the extent of forest damage, formation of an information fund on hazardous factors and processes that can lead to fires, assessment of the socio-economic consequences of fires, preparation of proposals for improvement of the activities of monitoring subjects - executive authorities and local governments on the issues of preventing negative changes in the field of natural security.
For the development of the IMS, an object-oriented methodology and Java multithreading technology were chosen. The use of multithreading technology in a distributed IMS made it possible to implement the requirements for simultaneous support of many users, each of which was allocated a separate thread, as well as the separation and parallel processing of information resources. All threads are executed independently of each other, so there is no blocking of users in the IMS, and it is possible to perform several operations at the same time.
The basis of the IMS is a database that contains information on forest and steppe fires with an area of over 5 ha, as well as peat fires with an area of over 1 ha. Information about fires in natural ecosystems contains: coordinates, the area of fire and smoke plume, the area of affected forests, natural meadows, farmland, its% of the total area, the presence and number of affected settlements, the presence and number of fire victims.

One of the long-term goals of the certification systems (FSC (Forest Stewardship Council) and PEFC (Program for the Endorsement of Forest Certification)) of sustainably managed forests that provide both social, environmental, and economic benefits is to completely phase out the use of chemical pesticides to protect planting material. It is in the interest of both nurseries and forest owners to find successful alternative, environmentally friendly solutions to safeguard pine saplings against Curculionidae. The studied two-year-old pine stands are located in the Hylocomiosa forest type with a total area of 4.27 ha. In 2016 clear-cutting was carried out, and in the spring of 2018, containerized seedlings were planted in areas with partial soil scarification in three repetitions in each area. Six plots with three variants in each of the repetitions were prepared. The work aims to evaluate the effectiveness of the use of P.sylvestris protection against damage Curculionidae while comparing untreated (control) lots with the ones treated with the systemic insecticide Actara or wax based on the number of damages and growth of seedlings. The intensity of tree damage and the incidence of damage over two years, depending on the type of seedling treatment, was assessed, and the average tree heights were measured and compared. With an increase in the incidence of weevil damage, the intensity of damage is also observed. At the same time, a significant (p>0.05) difference in lesions between the types of treatment of seedlings has not been established. Within two years, the death of trees due to weevil damage is insignificant - 2 % of all seedlings treated with the systemic insecticide Actara, 5 % of seedlings treated with wax Kvaae, and 6 % of untreated seedlings or control. The treatment of seedlings significantly affected their growth in the first and second years after planting (p less than 0.05). The use of wax Kvaae resulted in higher costs and similar protection effectiveness as the use of chemical means.

Published: March 2023

This study aims to observe the spatial distribution of the arthropods biodiversity inhabiting the soil surface of olive groves. For this purpose, a sampling campaign has been carried out in a 15.1 ha plot of this crop. This plot is located in the south of the Iberian Peninsula. The study comprised a total of 65 sampling stations for epigean arthropods. Each station consisted of two drop traps, one located under the canopy of the olive tree and the other in the middle of the strip. With the arthropod catch data from each sampling station, the Shannon biodiversity index per sampling unit was calculated. The average of the 65 stations amounts to a biodiversity value of 1.66 for this index. It can therefore be considered to have a relatively low diversity. This is a normal result in cultivated systems. A study of this biodiversity index has also been carried out for the three most important orders of soil-dwelling arthropods: Coleoptera, Hymenoptera and Araneae. In these orders, very low biodiversity values were found, as the number of species counted was reduced. Respectively, the results were 0.49, 0.68 and 0.61. Subsequently, a kriging study was carried out to study the distribution patterns of the results obtained at the sampling stations. The patterns show a general enrichment in biodiversity from the highest and steepest enclaves to areas of lower altitude and lower slope. With respect to biodiversity within the three orders studied, the patterns have not been as evident. Particularly in the case of Araneae.

Published: March 2023

In a common understanding, tailings dumps are represented as categories of engineering constructions where mined underground rocks are stored together with the useful rock represented by underground coal. And the position of tailings dumps, ordinarily, is on the land around the mining operations. For their location, land is chosen that determines the minimum impact on the environment and requires some of the lowest waste disposal costs. Considering that our world is in a continuous ascension, new techniques and methods are present in many fields of engineering, presenting themselves as a modern approach to the conservation, and the greening of the affected areas. In order for greening to be found in the main purpose of the study, it is necessary to arrange, geometrize, weed, and forest the storage area on the studied surface of 3.68 ha. Thus, for better coordination of the works, for aerial determinations a UAV type equipment, namely a Phantom 4 drone, and for ground determinations of the outline of the tailings dump and reference points, a GPS equipment, model Leica GS08, RTK method was used. Such a combination between satellite and photogrammetric methods; led to the creation of a 3D model as true to reality as possible that will be fundamental in the process of afforestation of the tailings dump.

Published: March 2023

For the purposes of ecological monitoring, the features of living ground cover and forest floor in spruce stands within Moscow urban territory were studied. Using ecological scales by Nitsenko, Ramensky, Ellenberg and Landolt, let to consider, that ruderalization of living overground cover is a result of recreation. Independently of spruce forest type, the absence of undergrowth results in increasing light penetrating and increasing species quantity. Variety of ecological spaces is a result of moderate trampling, which is mostly expressed in between-crown spaces. Hight trophy index by L.G. Ramensky is a result of increased weediness of overground cover. It is shown, that living overground cover characterizes the variety of tree layer and the level of anthropogenic impact on phytocenosis.The forest floor in urban spruce stands is sensitive to changes in functioning conditions and can be used for ecological monitoring. Availability of forest floor studying and simplicity of parameter estimation allows getting information about organic matter accumulation in express-regime under various degrees of anthropogenic impact on urban ecosystems. Within the system of trunk, crown and open space, the simplification of litter structure and decreasing organic matter total deposit are observed - this can be considered an invariant process.Maximal uniformity of coverless spaces litter, composed by needles and branches, results from absence of living overground cover, in combination with low recreation in these spaces. This fact let to conclude, that coverless spaces are able to be used as most important objects for comparing spruce ecosystems with different overground cover. Two groups of indexes, characterizing structure-functional litter organization, are proposed. Indexes, characterizing structural litter organization, include the total deposit of litter and L horizon deposit. Indexes, characterizing functional litter features, include deposit and proportion of detritus as well as the same for easydecomposed components, ratio of thickness (deposit) of L horizon and F horizon. The peculiarities of long-term spatial functioning are characterized by litter typology in the system trunk-crown-open space

Published: March 2023

The practice of using isotope analysis in archaeological research, which has been developing in recent years, requires knowledge of the features of isotope fractionation in cultural layers and buried soils. The structural properties of geoarchaeological monuments are determined by local relief, climate, vegetation, landscape hydrology, physical and chemical properties of soil-forming and underlying rocks, and the existence of crops, and therefore their isotopic signature has a complex cumulative character. The aim of the study was to study the variability of the carbon isotope composition of soils, rocks and cultural layers of various landscape parts of geoarchaeological mounds in dif erent natural zones of the Russian Plain from the standpoint of identifying general climatic trends and the contribution of the anthropogenic factor to carbon isotope fractionation. The defensive ramparts of the Dmitrovsky Kremlin (Moscow region), Davydovsky settlement (Tambov region), Vodyansky settlement (Volgograd region), necropolises of the Zhereno and Kvetun archaeological complexes (Bryansk region) were chosen as objects of study. It is shown that a signif cant variability in the carbon isotope composition is typical for soils and cultural layers of geoarchaeological monuments of dif erent natural zones and makes it possible to identify the stages of stable soil formation on the surface of embankments and the stages of backf lling structures. The isotopic ratios decrease in the humus horizons of daytime and buried soils. An increase in isotopic ratios is characteristic of the cultural layers of geoarchaeological monuments in all natural zones and marks the epochs of the existence of cultures, however, the mechanisms of this process require further research. Despite the predominant distribution of herbaceous vegetation on the day surface of the sites, the isotope signature of buried soils ref ects the type of dominant zonal vegetation and, through features of the type of photosynthesis, makes it possible to reconstruct the climate features of the region at various chronostages of the existence of objects

The paper provides a comparison of the various techniques for investigation of radionuclide speciation in soils based on fractionation of radionuclides bonded with different soil components. The dates on speciation of environmentally signifшcant technogenic and natural radionuclides in soils contaminated from testing of nuclear weapons, accidents or incidents at radiation dangerous objects, mining and mineral products processing are presented. The review looks at inf uence of natural and anthropogenic factors on the forms of the radionuclide compounds like the radionuclide and soil properties, type of radioactive fallout and the time elapsed af er fallout on soil. It has been demonstrated that experimental details of radionuclide speciation provide the basis for estimates and projections their mobility in soils, availability for plants and development of recommendations on reducing their penetration into food chains.

Authors: Gunawan Didik , Febrianti Indriana
Published: March 2023

The purpose of this study is to test the ability of the ARIMA model to predict the value of Ethereum, especially during economic shocks such as the current COVID-19 pandemic. The population in this study is Ethereum value weekly data for the period January 2017 to December 2020, so there are 208 samples in this study. The results showed that the use of the ARIMA method in predicting the value of Ethereum got poor results, where the forecast value was very much different from the actual value. This is evidenced from the results of the accuracy test using MAPE which got a result of 51.94%. On the other hand, the economic conditions that are experiencing uncertainty due to the COVID-19 pandemic and the emergence of deficit (decentralized finance) in early 2021 have pushed up a very significant increase in the value of Ethereum so that the error standard is higher and reduces the ability of the ARIMA model to predict the value of Ethereum. Further research is recommended to use a more advanced model such as the Autoregressive Fractionally Integrated Moving Average (AFRIMA) in order to obtain a better forecast value.

Authors: Hutabarat Willy , Syahnur Sofyan , Dawood Taufiq C
Published: March 2023

In the globalization era, poverty is one of the world's fundamental problems, especially in developing countries. With living standards often poor in developing countries, poverty will only get worse in the future. Thus, the current study investigates the relationship between poverty with population growth, economic growth, income inequality, and the unemployment rate in Indonesia. The data used is data from 33 provinces compiled by the Indonesian Central Bureau of Statistics. The results showed that population growth positively affected poverty severity. The economic growth variable has a positive effect on the poverty rate. Income inequality has a positive effect on the poverty gap and poverty severity. Also, the unemployment rate variable positively affects the poverty rate, poverty gap, and poverty severity. Based on these findings, it is suggested that the government maintain stable population growth, create an economy that all groups can enjoy, equitable distribution of infrastructure, social and economic development, and provide more employment opportunities. In addition, a poverty alleviation policy is needed that is sustainable from time to time.
Multiscale contextual emergence of neural dynamics, cognition and action.
Authors:   Department of Philosophy, Director of Cognitive Science Program Wenger Center, Elizabethtown College Elizabethtown, PA 17022, USA, Silberstein Michael
Published: March 2023

There is growing evidence that brain processes involve multiscale overlapping networks and that the mapping between such neural processes and cognitive functions is many-to-many. So, the answer to the question what spatiotemporal scales in the brain are most relevant for cognition, action, experience, etc., is that several inextricably interconnected and integrated scales are relevant. There is also growing evidence that brains and embodied agents (people) are part of “larger” distributed “bio-psycho-social networks.” One cannot fully appreciate what brains do and how they work in isolation from these larger multiscale, multi-level, and multi-faceted “4E” networks (embodied, embedded, extended, and enactive). Nor can one explain human experience, cognition, or action without such an understanding. Establishing these claims is the purpose of this paper. Part 1 will unpack the claim that the brain itself is best viewed as several multiscale, dynamical, multifunctional, coordinated, and fully integrated overlapping networks. Furthermore, such individual brain networks and conscious cognitive agents are embedded in “larger” “4E” dynamical networks. Part 2 argues that the best characterization of such 4E networks is not in terms of mechanistic reduction or modularity, but contextual emergence. Part 3 will draw key connections between contextual emergence and the related work of other philosophers and neuroscientists. Lastly, Part 3 will conclude that conscious cognitive agents are reasonably conceived of as highly non-decomposable “4E” contextually emergent multiscale dynamical systems. In short, people are not brains and brains are not computers.

Published: March 2023

This study was conducted to compare the reading level based on the assessment to determine the perceived effectiveness level in establishing community learning centers and their views on implementing the CLCs to redesign the project implementation plan. Sequential explanatory of mixed method design was used to complete this action research. The study involved thirty (30) learners as research participants. Specifically, using stratified sampling, ten (10) learners in each Grade level in 4, 5, and 6. The target respondents have undergone focus group discussion through home visitation to gather the needed data through an interview and conduct the PHIL-IRI Test as a reading assessment. Then, documentary analysis was used based on the results for developing the target output. The study found out that although Community Learning Centers were perceived to be effective, the following can be considered for improvement: Establishing CLCs to establish rapport with community members such as parents, youth, LGU, and other stakeholders; CLCs as a venue for material distribution and retrieval; and CLCs to encourage volunteers to assist teachers in the delivery of quality learning instruction to learners. This study implies that CLCs must be the teachers’ and community members’ responsibility. Teachers and School Governance Council should work hand in hand in sustaining the establishment of CLCs in every Sitio.

Authors: Villacrés Camino María Augusta , Solis Carrasco Ana Alexandra
Published: March 2023

En el mundo actual, el idioma inglés es considerado como una lengua franca debido a su importancia. Sin embargo, algunos de los estudiantes que deben tomar clases de inglés en el Centro de Lenguas de la Pontificia Universidad Católica del Ecuador Sede Ambato, no son conscientes de ello y presentan falencias en la adquisición del idioma, más aún al momento de aprender vocabulario. Por lo que resulta importante realizar esta investigación en la cual se aplica la mímica como estrategia para que los estudiantes aprendan nuevas palabras de manera efectiva y a la vez motivadora. En este sentido, el objetivo general de esta investigación es promover el aprendizaje de vocabulario del idioma inglés mediante el uso de la mímica; estrategia que pretende captar la atención de los estudiantes y lograr que aprendan el vocabulario del idioma inglés de una manera fácil y divertida, a la vez que adquieren y amplían su léxico de forma natural y sin presión alguna. El diseño de la investigación es cuasiexperimental debido a la aplicación de un Pre-posttest para identificar las falencias de los estudiantes al aprender vocabulario, así como para obtener información útil acerca del progreso de los estudiantes después de la intervención. Por otra parte, el enfoque de la investigación es cualitativo y el instrumento utilizado para la recolección de datos es el Pre-posttest. Una vez finalizado el trabajo de investigación, se observó que los estudiantes pudieron aprender, retener y recordar una gran cantidad de palabras de vocabulario de una forma amena, lo cual hizo que ellos se sientan seguros al usar el L2 para transmitir sus ideas. Como se demuestra en los resultados, los estudiantes obtuvieron un promedio de 55.45 en el Pretest y 92.85 en el Post test. Por lo que se concluye que la aplicación de la Estrategia de Mímicas tiene un efecto significativo en el aula de clases de EFL.
Estilos de aprendizaje en estudiantes universitarios: una descripción integral al iniciar la formación profesional
Authors: Caizapanta Suárez Jessica
Published: March 2023

El estilo de aprendizaje se constituye en la manera en que los estudiantes estructuran, utilizan y analizan conceptos, interpretan información, resuelven los problemas tanto académicos como emocionales. Conocer las características de los estilos de aprendizaje de los estudiantes permitirá que la educación superior considere esta variable en la ejecución de sus procesos formativos. En este sentido, contribuirá en la constante búsqueda de calidad de las instituciones de educación superior, especialmente en los primeros años en los cuales existe un gran porcentaje de deserción. Esta investigación pretende caracterizar los estilos de aprendizaje que presentan los estudiantes de primer nivel de una universidad particular ubicada en el centro norte de la ciudad de Quito. El método propuesto es cuantitativo con un nivel descriptivo, y un diseño transversal. Se utilizó como instrumento la adaptación al español del Inventario de los Estilos de Aprendizaje (IEA) de Vermunt (1994). El estudio contó con la participación de 271 estudiantes de primer nivel de grado de las siete facultades. Como resultado se encontró que los estudiantes que cursan el primer nivel de universidad presentan un estilo de aprendizaje dirigido a la aplicación.

Nnimmo Bassey: The Activist and His Poetry of Environmental Activism
Authors: Udoinwang David Ekanem , Akpan Kufre Aniefiok
Published: March 2023

Nnimmo Bassey’s poetic oeuvre projects environmental concerns, as presently occupying prominent place in Nigerian literary sphere, thus, twining this literary voice with the momentum of the ongoing global ‘greening’ campaigns. However, in the Nigerian situation, a sustained undertone of anger, protestation and ethno-political activism remains pronounced in the contemporary context of environmental literature. After the brutal execution of the prominent Ogoni-born ethnic nationality rights activist, environmentalist and writer, Ken Saro-Wiwa, by the Sani Abacha military dictatorship in 1995, Nnimmo Bassey’s environmental watch persists and vehemently echoes in his poetry. His voice has come to serve as a veritable instrument that re-echoes the passionate outcry and activism of Ken Saro-Wiwa. This poetic voice thus reverberates most vociferously in the Nigerian literary firmament and in global environmental action project. This paper, therefore, examines the social import of the convergence of artistic endowment and ecological consciousness in Bassey’s poetry, using ecological postcolonialism as analytical tool. Thus, the conclusion of this work is that artistic talent could be harnessed to advance the cause of socio-political re-engineering of society.
The Primacy of Mother: Reflections on “Hare, Elephant and Their Mothers” through Kristevan Lens
Authors: Dipio Dominica
Published: March 2023

This study analyses the concept of motherhood as that which transcends particular cultures in order to gain deeper understanding of it. It focuses on one familiar folktale that is diffused among ethnicities in Uganda and East Africa. This is the story of “Hare, Elephant and their Mothers”. Trickster Hare, in this story, proposes to his friend, a fellow bachelor, that it would be better to kill their old mothers in order to capture the attention of marriageable young women. The problem the story navigates is the position of a mother in the life of her son. To engage this story, I use the psychoanalytical perspective of Julia Kristeva, particularly as articulated in two of her articles, “Stabat Mater” and Narcissus: The New Insanity”. This perspective opens a fresh appreciation of the fascinating relationship between mother and child – particularly the son – that transcends cultures. As shown in both the theory and the folktale, the mother’s relationship with the son is characterised by entanglement with the ‘other’ self that she cannot be extricated from. To kill one’s mother can only be a trickster’s distasteful joke, for the line between mother and child is often blurred, as seen in Tales of Love (1987), where Kristeva theorises the child as an extension of the mother.

Kouluissamme siirryttiin keväällä 2020 lyhyellä ennakkovalmistautumisella etäopetukseen koronapandemian vuoksi. Samaan aikaan asetettiin rajoituksia myös harrastustoiminnan ja yleisötilaisuuksien järjestämiselle sekä suljettiin julkisia tiloja. Nuorten arki muuttui keväällä äkillisesti ja arvaamattomasti. Tutkimuksessa tarkastellaan ala- ja yläkoulun oppilaiden sekä lukion opiskelijoiden poikkeusolojen aikaista hyvinvointia unen, ruokailun, liikunnan, vuorovaikutuksen, osallisuuden, yksinäisyyden ja kiusaamisen näkökulmista. Lisäksi selvitetään, miten nämä tekijät olivat yhteydessä heidän hyvinvointinsa muutokseen etäjakson aikana. Empiirisenä aineistona käytetään kevään ja kesän 2020 aikana oppilailta (n=970; peruskoululaiset ja lukiolaiset) kyselyjen avulla kerättyä tietoa. Tutkimustulosten perusteella etäjakson aikana tapahtui oppilaiden hyvinvoinnin eri osa-alueilla yleisemmin kielteisiä kuin suotuisia muutoksia. Oppilaat nukkuivat keskimäärin enemmän ja kiusaamista ilmeni vähemmän kuin normaalin koulunkäynnin yhteydessä, mutta muissa hyvinvoinnin osatekijöissä muutos ei ollut suotuisaa. Noin kolmannes vastanneista oppilaista arvioi hyvinvointinsa heikentyneen etäopetuksen seurauksena. Monet hyvinvointia heikentäneet piirteet olivat yhteydessä toisiinsa ja kasautuivat samoille nuorille. Arjen rutiinit ja niiden hallinta auttavat hyvinvoinnin säilyttämisessä.      Asiasanat: etäopetus, hyvinvointi, pandemiat, nuoret

Student well-being during distance learning during the COVID-19 emergency
In the spring of 2020, people’s daily lives changed suddenly and unpredictably due to COVID-19. This study examines the well-being of primary and secondary school students during the state of emergency from the perspectives of sleep, eating habits, physical activity, interaction, inclusion, loneliness, and bullying. In addition, the study explores how these factors were related to changes in student well-being during the school lockdown. The empirical data were collected from students (n=970; primary and secondary school students) during spring and summer 2020 by means of questionnaires. The results show that during the distance-learning period, negative changes in different aspects of students’ well-being were more common than positive ones. Approximately one-third of the respondents estimated that their well-being had deteriorated as a result of distance. Many of the characteristics that had a negative impact on well-being were interlinked and clustered among the same young people.

Um Mapeamento Sistemático da Literatura sobre Pensamento Computacional na Perspectiva dos Fundamentos Teóricos de Aprendizagem
Authors: Garcia Julian Mubarack , Bittencourt Roberto A.
Published: March 2023

Há uma oferta crescente de formação em pensamento computacional (PC) para estudantes da educação básica devido ao potencial que o domínio de competências em PC traz para a formação de estudantes e profissionais do Século XXI. Conforme o ensino do PC se dissemina pelo mundo, é crescente a preocupação de professores e pesquisadores da área da educação em computação com a eficácia do processo de ensino e aprendizagem dos estudantes. Entretanto, neste contexto, muitas abordagens propostas costumam se preocupar mais com as tecnologias e linguagens do que com os fundamentos teóricos de aprendizagem por trás das abordagens propostas. Sendo assim, faz-se necessária uma visão sistêmica de como os referidos fundamentos têm impactado no ato de ensinar e aprender PC. Assim, este trabalho objetivou realizar um mapeamento sistemático da literatura (MSL) das evidências sobre a utilização destes fundamentos no contexto da formação em PC na educação básica, revelando uma carência neste sentido.
Reflexões sobre tecnologias digitais da informação e comunicação sob a perspectiva da educação hacker
Authors: Oliveira Aletheia Machado de
Published: March 2023

A presença das tecnologias digitais da informação e comunicação (TDIC) em diversas áreas da sociedade, inclusive na área educacional, proporcionaram modificações e efeitos na vida cotidiana das pessoas, como por exemplo, no comportamento, no trabalho, nos relacionamentos, na forma de se comunicar e de aprender. Diante disso, o propósito deste artigo é refletir sobre os usos efetivos das tecnologias digitais da informação e comunicação na educação nestes tempos tecnológicos, vislumbrando outras formas de fazer educação, sob a perspectiva da educação hacker. Ressaltamos, assim, que nosso estudo é de caráter teórico reflexivo com contribuições de Castells [1], Coll e Monereo [3], Pretto [4], Selwyn [5], dentre outros estudiosos. Apresentamos, em um primeiro momento, uma explanação conceitual sobre o termo tecnologia e um tipo específico de tecnologias digitais – da informação e comunicação, comumente chamadas de TDIC. Em um segundo momento, refletimos sobre a sua incorporação e usos na educação pensando em qual convite essa tecnologia deverá fazer ao meu aluno para, em seguida, contextualizar o movimento hacker e estabelecermos combinações possíveis com a educação. A partir desse estudo, vislumbramos um horizonte de possibilidades do espírito hacker às práticas pedagógicas para a necessária mudança de paradigma na educação.
