Hydrological model for the forecast of recessive flows: the case of the “Jequetepeque” river, upstream of the Gallito Ciego dam, Peru
Authors: Alvarez Villanueva Jairo Isaí , Huamán Vidaurre José Francisco
Published: May 2023

The research proposes a hydrological model to forecast recessive flows and it estimates a depletion coefficient for the "Jequetepeque" river, water from the top of the "Gallito Ciego",Contumazá, Peru. Recessive flows were used from the third break point of the flow hydrograph of the "Yonán" station of the "Jequetepeque" river, period 1988-2019. An exponential category hydrological model (ALVI) was used. Ranges of depletion coefficients 0.0148 < α < 0.0003 day-1, and a calibration coefficient of 0.005 day-1were identified. The proposed model, ALVI, was validated, and it is based on statistical indicators, such as: NS (0.84), RMSE (0.62), R2(0.97), EEE (0.66) and IWM (0.84). The statistical indicators indicated a high degree of efficiency, it isinside within the metric of the ranges of the statistical indicators. The hydrological model (ALVI) was validated: Qb=Q0 / (1+e [1.32*Ln ((Q0/Qf) -1)-(0.00049*Ln(A)+0.0057)*t]). The observed and simulated flows were identical tothe non-parametric Mann-Whitney U test. The RStudio Cloud program was used with a significance level of 0.05, it was determined from the median that the observed and simulated flows are similar or identical.

Authors: Fonseca Letícia Rodrigues da , Carvalho de Rezende Daniel
Published: May 2023

This paper aims to contribute to a better understanding of the current status of scientific production about anti-consumption through an integrative literature review that identifies international and national studies published in highly relevant journals. The method applied was proposed by Botelho, Cunha & Macedo (2011). A total of 101 papers published between 2011 and 2021 were selected at the end of the analyses. The objectives were to identify the main conceptual definition used in studies on this topic, the target audience, the level of analysis and arguments for anti-consumption, the most applied research method, and the scope of this research. Furthermore, this paper attempts to highlight the main criticism of this theory raised by the scholars in this field, clarify possibilities for future research and introduce a new theoretical model that summarizes how the anti-consumption phenomenon takes place in different contexts/situations according to the findings on the studies analyzed by this integrative review. Hopefully, this paper can contribute to advancing and developing this field at the theoretical and practical levels by setting a research agenda.

A questão da segurança desperta atenção de grande parte dos cidadãos brasileiros e ganha ainda mais força quando analisamos as alterações ocorridas na região da subprefeitura de Parelheiros. O presente trabalho tem por objetivo analisar como o crescimento populacional desordenado e irregular na área da Subprefeitura de Parelheiros entre os anos 2013 e 2020 causou impacto na segurança urbana da Cidade de São Paulo. Este estudo partiu de uma constatação de ampliação de irregularidades identificadas na área pela Divisão de Defesa e Vigilância Ambiental da Secretaria Municipal de Segurança Urbana. A metodologia quantitativa foi aplicada, analisando os dados dos boletins de ocorrências criminais oriundos da Secretaria de Segurança Pública do Estado de São Paulo que tiveram este território como local do crime, a evolução dos equipamentos públicos colocados à disposição da população, além da estimativa populacional do IBGE. A região objeto de estudo do presente trabalho é consumida pela necessidade de moradia e manobras do poder, na qual há desrespeito a natureza, devastação das áreas de floresta para construção de loteamentos clandestinos que muito rapidamente se transformam em bairros autoconstruídos e irregulares, ampliando o número de pessoas, comércios e a criminalidade local.

Authors: ARAS Uğur , KALAYCIOĞLU Hülya
Published: May 2023

In the present study, the effect of nano additives in different ratios added to melamine formaldehyde adhesives on the properties of particleboards was investigated. In this respect, two different nanoclays [organo-modified nanoclays (OMC) and unmodified nanoclays (NC)] and graphene nanoplatelet (GNP) were added to the adhesive at the rate of 1%, 2% and 4%. Along with the physical (thickness swelling and water absorption), mechanical properties (modulus of rupture, modulus of elasticity and internal bond strength), accelerated weathering and fire resistance tests (Limiting oxygen index-LOI) of the board were carried out. According to the results, while there was no significant change in the water absorption values with the use of nano additives, a decrease occurred in the thickness swelling values with the use of GNP. The mechanical properties increased with the use of nano additives. The highest values were obtained from the board groups using 1% GNP. The loss of mechanical resistance values after the accelerated weathering test was reduced with the use of 1% nanoclay and up to 2% GNP. According to LOI test results, the use of 1% and 2% nano additives increased the fire resistance of the boards., The agglomerations were determined in places with the increase in the nano additive ratio in the SEM images.
CO2 emission from soil irrigated with recycled wastewater at different levels and the relationships of emission with soil properties
Authors: YERLİ Caner
Published: May 2023

The use of recycled wastewater in agricultural irrigation contributes to ecosystem by reducing the discharge of wastewater to the environment, as well as increasing soil quality with fertilizing effect. However, since the high nutrient of wastewater can make the soil a source of CO2 emission, it is necessary to know the relationships between CO2 emission and soil properties to the management of emissions. This study aimed to determine the relationships between CO2 emission and soil properties by examining the changes in the properties of soil irrigated with recycled wastewater and freshwater at different levels. The results showed that the recycled wastewater caused 58.1% more CO2 emissions than freshwater in full irrigation treatments, while the emissions decreased in the range of 8.8% to 44.5% with increased deficit irrigation. In addition, the significant relationships of CO2 emission with EC, pH, CaCO3, organic matter, total N, P2O5, K2O, cation exchange capacity, porosity, aggregate stability properties of the soil and H2O emission from the soil, soil moisture and temperature at different depths were determined, demonstrated the effectiveness of these parameters in the management of CO2 emissions in soil irrigated with recycled wastewater. Considering the obtained findings, it was determined that deficit irrigation is very effective in reducing CO2 emission and considering the effectiveness of soil temperature and soil properties on the emissions, CO2 emission can be reduced by soil temperature and soil properties management, and more comprehensive studies on this subject could suggest.

Günümüzde iklim değişikliğinin en önemli etkilerinden biri olan ekstrem hava koşullarının görülme sıklığının ve şiddetinin artması, ormancılık faaliyetleri üzerinde de rol oynamaktadır. Örneğin, yüksek sıcaklıklar ve kuraklık, ormancılık çalışmalarını olumsuz etkilediği gibi düşük sıcaklıklar da bu çalışmaları olumsuz yönde etkilemektedir. Düşük sıcaklık stresi bitkilerin büyümesini, verimliliğini ve yayılış alanlarını etkileyen önemli bir stres faktörüdür. Özellikle ağaçlandırma çalışmalarında başarılı olunabilmesi için dona dayanıklı türlerin ve orijinlerin belirlenmesi gereklidir. Daha önce yapılan don stresi çalışmalarında dona dayanıklılık bakımından popülasyon içi farklılıklar olduğu belirtilmiştir. Bu çalışmada kızılçamda Akdeniz Bölgesi Yüksek Islah Zonunda bulunan Gölhisar orijinli ailelerin soğuğa dayanıklılık varyasyonunun ortaya konması amaçlanmıştır. Başlangıçta 28 aileden tohum toplanmasına karşın sadece 26 aileden yeterli fidan edilmiştir. Dona dayanıklılık testleri dokuz sıcaklık kademesi (-5,-10,-15,-17.5,-20,-22.5,-25,-30,-40 °C) ve kontrol (+4 °C) kullanılarak 1+0 yaşındaki fidanlardan elde edilen sürgünler üzerinde, her bir sıcaklık kademesinde bir aile için 5 tekrarlı olarak 2022 yılı Şubat ayında gerçekleştirilmiştir. Don stresine tabi tutulan sürgünlerde oluşan don zararı klorofil floresans yöntemi ile belirlenmiş ve fotosentetik verimlilik verileri kullanılarak analizler yapılmıştır. Araştırma sonucunda dona dayanıklılık bakımından aileler arasında istatiksel ( p<0.0001) olarak fark bulunmuş ve Tukey HSD testi ile aileler gruplandırılmıştır. Ancak Tukey HSD testi ailelerin zarar gördüğü sıcaklık kademe aralıklarını verdiğinden ayrıca her aile için düşük sıcaklık ve doku zararı arasındaki ilişki doğrusal olmayan model yürütülerek Lethal Temprature %50 (LT50) değerleri hesaplanmıştır. Çalışılan ailelerde don zararı -17.5 °C’den sonra başlamış ve dona dayanıklılık düzeyi en yüksek -22.9 °C ile 8569 nolu aile, en düşük ise -18.7 °C ile 8587 nolu aile olarak belirlenmiştir.

TLC-CLIP v1

Published: May 2023

RNA-binding proteins are instrumental for post-transcriptional gene regulation, controlling all aspects throughout the lifecycle of RNA molecules. However, transcriptome-wide methods to profile RNA-protein interactions in vivo remain technically challenging and require large amounts of starting material. Herein, we present an improved library preparation strategy for crosslinking and immunoprecipitation (CLIP) that is based on tailing and ligation of cDNA molecules (TLC). TLC involves the generation of solid-phase cDNA, followed by ribotailing to increase the efficiency of subsequent adapter ligation. These modifications result in a streamlined, fully bead-based library preparation strategy, which eliminates time-consuming purification procedures and drastically reduces sample loss, allowing the profiling of RNA-protein interactions from as few as 1000 cells. In the accompanying manuscript, we have applied TLC-CLIP to four endogenous RNA-binding proteins, demonstrating its reproducibility and improved precision due to a higher number of crosslinking-induced deletions that serve as an intrinsic quality metric and increase both specificity and nucleotide-resolution.

Reading ability is a person's ability to understand written content and then manifest it by reciting it orally. The ability to read is the basis for developing one's language skills because Arabic is always related to Arabic texts. The problem found by researchers at Madrasah Diniyah Almunawarotul Banat is the need for students' ability to read and understand the contents of Arabic texts. This study aims to improve the reading skill (maharah qiraah) of fifth-grade students at Madrasah Diniyah Almunawarotul Banat in learning Arabic using the Strip Story method. This research is a classroom action research (CAR) that focuses on action research, which consists of two cycles, with the subject being fifth-grade students at Madrasah Diniyah Almunawarotul Banat, a total of 20 people. The results of this study indicate that the method of story strips can improve students' ability to read Arabic texts. In the first cycle, only a small number of students could read Arabic sentences, with an average of 66.5%. In the second cycle, almost 80% of students could read Arabic texts; judging from the average obtained, it was 75.45%.

Published: May 2023

Bu çalışma üniversite öğrencileri ile gerçekleştirilen çalışmalarda yaygın olarak kullanılan üç farklı depresyon ölçeğini eşitleyerek bir puan dönüşüm tablosu oluşturmayı amaçlamaktadır. Veriler üniversitede öğrenim gören 1038 lisans öğrencisinden toplanmıştır. Öğrencilerin depresyon düzeyini ölçme için Beck Depresyon Envanteri, Epedimiyolojik Araştırmalar Merkezi-Depresyon Ölçeği ve Depresyon-Kaygı-Stres Ölçeği kullanılmıştır. Eşitleme işlemi gerçekleştirilmeden önce bu işlem için önerilen ön koşullar incelenmiştir. Sonrasında, eşitlemenin madde tepki kuramı modelleri ile analiz uygulanabilirliğini değerlendirmek için tek boyutluluk ve yerel bağımsızlık varsayımları incelendi. Son olarak tek grup deseni ile toplanan veriler eşit yüzdelikli eşitleme yöntemi ile ortak bir metriğe aktarılmıştır. Gerçekleştirilen bu analizler için R istatistik programı kullanıldı. Elde edilen bulgular eşitleme varsayımlarının karşılandığını göstermektedir. Diğer taraftan, verilerin Madde Tepki Kuramı modelleri kullanılarak eşitlenmesi için uygun olmadığı belirlenmiştir. Bu doğrultuda eşit yüzdelikli eşitleme yöntemi için gerçekleştirilen analizlere dayalı olarak puan dönüşüm tablosu oluşturulmuştur. Sonuç olarak, Beck Depresyon Envanteri için hafif düzey depresyon belirti düzeyi için belirlenen kesme puanının ile Depresyon Kaygı Kaygı ölçeğinin depresyon alt boyutu için belirlenen kesme puanının örtüştüğü; Epidemiyolojik Araştırmalar Merkezi Depresyon Ölçeği için belirlenen kesme puanının ise Beck Depresyon Envanterinde şiddet olarak “hafif” düzeye karşılık geldiği görülmüştür. Yani, depresyon ölçüm araçları için belirlenen kesme puanları örtüşmemektedir. Ayrıca, depresyon ölçeklerinin ölçtükleri depresyon şiddet yelpazesinin örtüşmediği söylenebilir. Nihai olarak, oluşturulan dönüşüm tablolarının kullanılması ile birlikte, araştırmacı ve profesyonellerin elde ettikleri puanları farklı depresyon ölçeklerin kullanıldığı araştırmalarda elde edilen puanlar ile de karşılaştırmalarının gerekliliği görülmüştür.
The Relic Landscapes of the Grazer Bergland: Revisiting the Piedmonttreppen Debate
Authors: Stüwe Kurt , Hohmann Konstantin
Published: May 2023

The Grazer Bergland is a mountainous region at the eastern end of the Alps that escaped glacial erosion in the Pleistocene and thus preserves low-relief landforms that are relics of the earlier uplift history. These relic landforms may reflect a Piedmonttreppe that formed during a series of stages of a wide-reaching Pliocene uplift event that interacts with the landscape evolution, but this model is not uniquely accepted for the region. In order to test this model and for a future better correlation of the paleosurfaces with those mapped in other regions, it is important to benchmark these relic landforms. We do so by presenting a geomorphic map of the Bergland region over some 600 km2. We describe the well-known levels Stadelberg/Zahrerberg- (at 540 – 700 m a.s.l.), Kalkleiten/Hochstraden- (at 700 – 850 m a.s.l.), Trahütten- (at 950 – 1100 m a.s.l.), Hubenhalt- (at 1200 m a.s.l.), as well as Wolschenegg- and Kor- (at 1200-1720 m a.s.l.) levels and correlate their distribution in space and time. Fluvial channels between segments of the relic surfaces have knickpoints that correlate with the planation surfaces, which is in strong support of the Piedmonttreppe model. Our analysis results in a model that interprets the course of the Mur river to be the product of a river piracy event near Peggau at the time of the planation of the Trahütten level (about 4 Ma), diverting the paleo-Mur from an eastwards course along the Mürz valley in direction Vienna, towards Graz. Thereafter, the Mur remained antecedent with respect to the uplift of the surrounding massifs resulting in massive base level drop for many tributaries, like the Mixnitzbach or Rötschbach. The resulting knickpoints have since migrated upstream to cause successive minor river capture events, for example the Rötschbach capture at Kesselfall. We also show that the presence of lower levels in the Passail Basin is best interpreted in terms of the more efficient erosion of basin sediments that filled a Miocene half graben north of the Schöckl ridge and analyze the two major drainages of the region, the Raab and the Weizbach.
Stratigraphic architecture of a mixed clastic-carbonate succession and 87Sr/86Sr-based chronostratigraphy along the margin of a synorogenic extensional basin (Hochmoos Formation, upper Santonian, Northern Calcareous Alps)
Authors: Kearney Kevin , Wagreich Michael , Sanders Diethard
Published: May 2023

The Gosau Group (Turonian to Ypresian) of the Eastern Alps is a synorogenic wedge-top succession that accumulated in active depocenters in an oblique-convergent plate tectonic setting. Due to high morphological differentiation of depocenters by tectonism, the Gosau Group displays a wide range of facies as well as marked facies heteropy and thickness variations over short lateral distances. In the area of the locations Gosau and Russbach, the Hochmoos Formation along the SE basin margin near Gosauschmied comprises coastal to shallow-marine deposits and small rudist bioconstructions and was investigated by way of field mapping, profile descriptions, microfacies analysis, isotope measurements and assessment of fossil content.

Strontium isotope ratios (87Sr/86Sr) from 0.707485 (oldest) to 0.707549 (youngest) indicate a latest Santonian age, with the youngest parts of the Hochmoos Formation possibly extending into the Campanian. On the west side of the study area, the succession of lithologies and fossil content record transgression of a fan-delta to marginal-marine environment (lowstand to transgressive systems tract), followed by shallow neritic deposition (part of the transgressive systems tract) and, finally, by progradational stacking of limestone beds in the highstand systems tract, culminating in growth of rudist thickets in an inner shelf and partially protected ‘lagoonal’ milieu. Eventually, at the inception of the following falling stage systems tract, input of large clasts of Dachstein Limestone, quartz and chert record a recurrence of the subaqueous part of a fan-delta. On the east side of the study area, a preponderance of rudist-clastic limestones over a few rudist biostromes preserved in situ indicate a normal-marine environment punctuated by high-energy events, such as storms or tsunami. The scarcity of benthic foraminifera and the presence of only isolated specimens of colonial corals underscore a habitat with a calcarenitic substrate frequently shifted by currents. Several lines of evidence indicate that the western part of the study area was more proximal relative to the eastern one. With a maximum thickness of 68 m, the Hochmoos Formation at Gosauschmied is slightly thicker and more distal than outcrops located nearer to the basin margin and farther towards the SE (Schmiedsippl, Katzhofgraben), but significantly thinner than the nearly 300 m at Gosau Pass-Gschütt, or the thickness of 170 m observed in the area of Rigaus-Abtenau farther in the West. These thickness variations are interpreted as a result of extensional syndepositional tectonism. At Gosauschmied, the vertical arrangement of facies records a cycle of relative sea-level change that may have been tectonically enhanced.
Motivar el emprendimiento universitario a través del aprendizaje-servicio

The education system offers specialised training in professional skills for running new companies that students often fail to use due to a lack of entrepreneurial motivation. As an alternative, the faculty of Strategic Management I at the University of A Coruña (UdC) proposes an activity to stimulate entrepreneurship through an indirect action. Over the course of a semester, students must prepare a case study of an organisation in their area. They have to carry out a strategic analysis, identify its strategic formulation and propose improvements and growth vectors. They are confronted with two types of organisations: profit and non-profit organisations. The students' continuous contact with the organisations promotes commitment to their vision and values, indirectly stimulating their entrepreneurial vocation. The results of this experience show the greater potential of Non-Governmental Organisations (NGOs) in stimulating entrepreneurial vocations.
Crebando miolos. A promoción da aprendizaxe cooperativa a través da técnica puzzle

Published: May 2023

This experience of teaching innovation has been designed for face-to-face teaching in the subject Information and communication technologies applied to speech therapy intervention, optional for the 3rd year of the Degree in Speech Therapy. Due to its characteristics, this proposal could be adapted to part-time teaching or even teaching in a completely virtual format. Based on the application of the puzzle technique and with various phases (moving from individual to cooperative work, through the group), the dynamic is based on gaining a broad knowledge of applications and web resources useful for speech therapy intervention, culminating in the creation of a virtual and collective environment for learning that collects all the work developed throughout the course, of present and future utility. With the emphasis on promoting student participation and motivation, from a truly cooperative approach, and from an orientation to content creation, the results allow us to contrast the effectiveness of the proposal in the dimensions mentioned, both academically and in teacher and student satisfaction. However, the designed methodology seems useful to address the competencies of this subject, with the possibility of being applied in other degrees, subjects or courses, with the relevant adaptations.

Due to the evolution of education, and in the current context, it is necessary to adapt educational planning to a new scenario. This new planning entails, among others, the great challenge of adapting face-to-face laboratory practices in higher education so that they can reach all students. An alternative that is being used is the use of virtual scenarios, instead of face-to-face laboratory practices, thanks to the use of software applications. For the specific case of subjects related to automation and control, these scenarios can be achieved with tools such as Factory I/O, which, thanks to the use of the KEPServerEx program, can be interconnected with MatLab/Simulink. This document will expose some scripts (MatLab programs) that have been created to be able to carry out control practices, with similar characteristics to real laboratory plants that are available in University laboratories. In addition, these scripts have been made in such a way that the student can change from the virtual environment to the real one in a simple way.

The new paradigms derived from the implantation of the European Higher Education Area entail a relevant increase in the use of active methodologies focused on the development of competences, encouraging the participation and involvement of the student in the learning process. In the context of the Degree in Computer Engineering at the Universidade da Coruña, different itineraries or mentions are offered, which in addition to the general and transversal competences, deepen in the competences of each speciality. The Final Degree Project (FDP) of this degree deals with complex real-world problems that often require skills from different specialisations. With the aim of ensuring that the students acquire specific knowledge from other specialisations as a complement for the preparation of their FDP, this work proposes a teaching innovation strategy based on multi-speciality cooperative learning with FDP students from the mentions in Software Engineering and Computing. In order to evaluate the impact of this teaching innovation strategy, the students involved have answered an anonymous questionnaire, showing in general a high degree of satisfaction regarding the level of learning, the development of competences as well as the overall appreciation of the proposal.

Moreover, On March 19, 2018, a matter regarding the nascent COVID-19 pandemic pushed the California government to command lockdown on all Californian residents, except to do certain primary tasks.

Results.  The study revealed that NO2 has a kind of linear correlation with COVID-19 (county-level mortality rates, including some other parameters) that also produced the O3. Additionally, ground-level ozone is confidently associated with COVID-19 cases (fatality rates). Additionally, s an outcome of lockdown, the usage of individual vehicles drastically lowered. Since these transportations significantly provided to NO2 levels in five mentioned counties of USA, many have queried whether their absenteeism let a drop in NO2 pollution.

Conclusions.  High NO2 concentrations and ground-level O3 object to a higher COVID-19 case and fatality rate. To check additional deaths, it is essential to follow lockdown limitations and also speculate research verdicts in public systems. In the fact of air pollution or contamination, environmental constraints should be augmented, and additional anticipations should be practiced as plants start resuming.

The problems of creating a propulsion system for a new generation supersonic passenger aircraft are considered on the basis of a review of the work on the supersonic transport being carried out in the world. It is shown that the desire to achieve high flight performance and commercial effectiveness of a supersonic passenger aircraft while meeting up-to-date environmental requirements leads to contradictory technical solutions regarding the propulsion system: the location and number of engines, the scheme of the air intake and nozzle, the choice of the scheme and design parameters of the engine, the use of new high-temperature materials in the engine hot section, etc. The features of the operating conditions of the engine components of a supersonic passenger aircraft in comparison with the engines of up-to-date subsonic civil aviation aircraft and supersonic military aircraft are indicated. The calculated estimates of the influence of various technical solutions on the parameters of the supersonic passenger aircraft engine are given. Due to the complexity and multi-criterion nature of the task of creating a supersonic passenger aircraft propulsion system, its solution requires an integrated approach based on close cooperation of specialists in airframe aerodynamics, engine, etc.

The reasons for the occurrence of increased vibration of the engine rotor due to aerodynamic imbalance of the fan of the first stage of the impeller are determined. A method for estimating the aerodynamic imbalance of the gas turbine engine fan is proposed, taking into account the influence of the following factors: geometric errors in the manufacture of blade airfoils and their positioning in the disk; deformation of the blade airfoil during the assembly of the impeller, as well as the factors of the working process occurring in the impeller. The use of the technique makes it possible to evaluate the aerodynamic imbalance of the impeller at the stage of its balancing and significantly reduce the amount of aerodynamic imbalance by determining the parameters for removing a layer of material or adding corrective masses. The influence of geometric errors of the blades on the value of the aerodynamic imbalance of the impeller was analyzed. Based on the results of the research, the type of dependence of unbalanced gas forces on the influence of technological and operational factors of the impeller under consideration was determined.

Published: May 2023

Objectives: This study aimed to explore the relationships between nurses’ work environment, job stress and job satisfaction, along with the moderating effects of work environment and empowerment on the relationship between job stress and job satisfaction. Methods: A descriptive correlational design was utilised for this study. The study encompassed a convenience sample of 1,796 hospital nurses from the 11 governorates in Oman. Moreover, a self-report questionnaire that included a set of instruments was used to collect the data. Results: Nurses who perceived higher levels of job stress reported lower levels of satisfaction and empowerment and perceived their work environment as less favourable and supportive. The findings only confirmed the direct effects of work environment and empowerment on satisfaction, whereas no support was found for indirect or moderating effects. Furthermore, the hierarchical regression model showed that 46.5% of the variation in the level of job satisfaction was explained by the study variables. Conclusion: The results of this study demonstrate the importance of implementing strategies that empower staff, provide a supportive and positive work environment and tackle job stress to enhance levels of job satisfaction.

Published: May 2023

This study looks at the critical problem of how to use Massive Open Online Courses (MOOCs) at the Republic of Kazakhstan’s technical universities. Its objective is to study how professional-oriented foreign languages can be taught as MOOCs. As a methodological basis, it uses system-activity and competence approaches. The theoretical side includes the analysis and generalization of foreign and local scientific works to determine the advantages and disadvantages of MOOCs in the development of professional foreign language skills for students with technical specialties. Data on the use of MOOCs was analyzed and summarized at Karaganda Technical University. The quantitative results of the experiment were obtained using mathematical statistics. The authors ran a comparative analysis of the results between groups with traditional and mixed teaching methods in the English for Special Purposes course. A mixed method with MOOC technology integrated delivers better results than traditional education. Empirical results demonstrate that this method improves communication skills in the main areas of speech activity, professional vocabulary expansion, and theoretical knowledge enrichment of students within their specialty. The results indicate that using MOOCs as part of the ESP course leads to better educational results in comparison to traditional education. The use of system-activity and communicative approaches unlocked new opportunities for students, like increasing English proficiency levels, developing critical thinking and time-management skills, solving problems, and advancing their knowledge of their discipline. The authors studied MOOCs in a small data environment using an alternative qualitative research analysis method and came to the conclusion that MOOCs are effective in ESP courses for engineering students.

Drama may be a useful technique for improving pupils' language acquisition in any subject. Implementing such a strategy in an actual classroom setting could be a problem for any instructor or person. The idea behind this study was to establish whether using drama-based activities in pedagogy has any positive educational outcomes. The study used a quantitative technique, and included a specific section about students’ perspective on data collection from over a thousand students. They are studying in different faculties in undergraduate courses where English is a compulsory subject. The researcher independently designed the research instrument which was used to elicit responses from learners. The data collection method uses purposive sampling in the present study. Activities that encourage language-learning skills include role-plays and extended role-plays, which are described in the research as drama elements that can be useful in teaching languages. The study's findings support the use of drama as a strategic approach and have a bigger influence on student learning results.

The introduction of multilingual education in the Republic of Kazakhstan meets the requirements of the time since globalization processes give rise to the need to integrate the state into the world community. Solution of topical issues of multilingual education necessitates solving problems with conscious regulation of the language situation. The aim of this study is the determination of the degree of implementation of multilingual education in the western region of Kazakhstan, which plays a significant role in the economy of the country as a whole. For diagnostics and measurement language processes, a questionnaire survey was used. The results of the study showed that the implementation of multilingual education in Kazakhstan is carried out purposefully and systematically: the social communicative functions of the state language have significantly expanded and strengthened in all spheres of society, and the development is proceeding quite rapidly English language and its practical application; positions of the Russian language remain stable as a language of international communication. At the same time, among children of preschool and primary school age, a tendency to prioritize the Russian language over Kazakh, which in the near future may greatly weaken the position state language. As a result, scientific recommendations are given for the adoption of timely and adequate management decisions in the field of language building in the region under study.
