Impact of Online vs. On-Campus Classes on Academic Performance of EFL Learners’ Speaking Skills
Authors: Abduh Mariam Yousef , Khan Mohammad Owais
Published: April 2023

Academic performance is an essential component of assessing the success of educational programs. During the coronavirus lockdown, educational institutions worldwide changed their methods of teaching to suit the new online mode of teaching. Consequently, many students, particularly EFL learners’ academic performance have been affected. This study reports the findings of online teaching’s impact on learners’ academic performance in the speaking course at the English Department, Najran University. This is mainly attempted through a comparison of students’ academic performance in online teaching mode in speaking courses during the Coronavirus lockdown with that of on-campus teaching mode before the Covid-19 lockdown. Data for the study were collected from the scores of the students in speaking skills, which included grades for the final exams. The data were collected from the participants (N = 80 students), 40 males + 40 females, who received instructions via both the on-campus and online teaching modes. The results of the study revealed that the variability in both modes of teaching was very distinct. Students’ grades in the on-campus mode of teaching did vary too much from grades in the online teaching mode. The scores of both modes of teaching similarly varied from A, B, C, D, and from failed, deprived, absentee, and withdrawn students. However, it has been found that the majority of the students performed better in the online teaching mode than on-campus.
Pragmatic Competence in Learner English: The Case of Jordanian EFL Learners
Authors: Hammouri Dina M. , Al-Khanji Rajai R.
Published: April 2023

The study investigates the Jordanian EFL learners’ pragmatic competence through their production of the speech acts of responding to requests, making suggestions, making threats and expressing farewells. The sample of the study consists of 130 Jordanian EFL learners and native speakers. 2600 responses were collected through a Discourse Completion Test (DCT). The findings of the study revealed that the tested students showed similarities and differences in performing the strategies of four speech acts. Differences in the students’ performances led to pragmatic failure instances. The pragmatic failure committed by students refers to lack of linguistic competence (i.e., pragmalinguistic failure), sociocultural differences and pragmatic transfer (i.e., sociopragmatic failure). EFL learners employed many mechanisms to maintain their communicative competence; the analysis of the test on speech acts showed learners’ tendency towards using particular strategies, resorting to one strategy related to their grammatical competence, prefabrication, performing long forms, buffing and transfer. The results were also suggestive of the learners’ lack of pragmalinguistic and sociopragmatic knowledge. The implications of this study are for language teachers to teach interlanguage pragmatics explicitly in EFL contexts to draw learners’ attention to both pragmalinguistic and sociopragmatic features, pay more attention to these areas and allocate more time and practice to solve learners’ problems in these areas. The implication of this study is also for pedagogical material designers to provide sufficient and well-organized pragmatic input.

Authors: Romanova Tatyana E. , Abaeva Olga P. , Romanov Sergey V. , Rodina Anjelika A.
Published: April 2023

BACKGROUND: This article is devoted to the impact of the digitalization of modern healthcare on the nature of relationships between a doctor and a patient.
AIM: To assess the level of readiness of the patients in the city hospital for the introduction of digital technologies in the system of providing medical services.
MATERIALS AND METHODS: The study was based on the results of a questionnaire survey of 154 patients in city hospitals in JulyAugust 2022 in Nizhny Novgorod. The survey questions included studying the use by modern day patients of various methods of digital communication with medical workers, the impact of the availability of medical information on the internet on the level of patients trust on a doctor, and patients opinions about the prospects for solving problems of modern healthcare through digitalization.
RESULTS: The results of the survey revealed that 104 (67.5%) patients do not use digital communications, and 94 (61%) have no intention of using them. Among the prospects for the use of digital technologies in healthcare, the most popular for respondents were getting referrals for medical services (n=83, 53.9%), a prescription (n=57, 37%), and documents certifying temporary disability (n=43, 27, 9%). Only 8 (5.2%) respondents systematically check the diagnoses and prescriptions received from the attending physician on the internet and 25 (16.2%) do this from time to time. Only 2 (1.3%) respondents stated that they have a priority level of trust in recommendations from internet sources, and the rest of the patients trust their real attending physicians more.
CONCLUSION: A modern patient seeks to receive medical care in real contact with a doctor, considering digital technologies mainly as a tool that addresses formal issues that arise when visiting medical organizations.

Authors: Grigoreva Ekaterina A. , Yeremina Maria G. , Krom Irina L. , Erugina Marina V. , Sapogova Maria D. , Zotova Yulia A.
Published: April 2023

BACKGROUND: One of the leading indicators of the social effectiveness of healthcare is the assessment, monitoring, and analysis of the social satisfaction of patients with medical care, which reflect the degree of implementation of a personalized approach of medical care. Patients satisfaction with their interaction with the healthcare system is a result of the main characteristics of the quality of medical care, established by the professional community.
AIM: To analyze the satisfaction of consumers of medical services in terms of the accessibility and quality of medical care in regional healthcare facilities.
MATERIALS AND METHODS: The study involved 218 doctors from primary healthcare medical organizations in Saratov and 312 doctors from primary healthcare medical organizations in districts of the Saratov region.
RESULTS: From the results of the research, we determined negative phenomena in the activity of medical organizations in which the respondents received medical care. Despite the limitation of medical care accessibility for the majority of respondents in the regional healthcare (the absence of the necessary specialists, insufficient technical equipment in the medical organizations, the high cost of medicines unaffordable by patients, and queues), while assessing the satisfaction with medical care in the medical organizations of the region the majority of the respondents (63.8% of respondents in the medical organizations of Saratov and 64.9% in medical organizations of Saratov region) evaluated their satisfaction with medical care positively.
CONCLUSION: The explanation of the results obtained is possible in the context of the description by Academician of RAS A.V. Reshetnikov the phenomenon of paradoxical medicine, which appeared in the Russian healthcare literature at the end of the twentieth century.

Published: April 2023

Background and Aims: Coronavirus disease-2019 is an emerging disease of global public health concern. We aimed to evaluate the demographic data, clinical properties, risk factors and endoscopy findings of coronavirus disease-2019 patients with upper gastrointestinal system bleeding. Materials and Method: Patients who underwent endoscopy for upper gastrointestinal bleeding between July 2, 2020 and January 29, 2021 and were diagnosed with severe acute respiratory syndrome coronavirus-2 confirmed by polymerase chain reaction were included in the study. In this retrospective study patients with gastrointestinal bleeding were compared as 1:2 case-control. Coronavirus disease-2019 patients who underwent endoscopy for upper gastrointestinal bleeding and the control group were compared retrospectively in terms of demographic data, comorbid diseases, bleeding symptom, drugs administered, laboratory parameters, time between bleeding symptom and endoscopy, endoscopy findings, gastrointestinal bleeding treatment, and mortality rates. Results: Forty Covid-19 patients (23 males, mean age ± SD, 65.92 ± 12.97) and 80 non-Covid-19 control patients (43 males, mean age ± SD, 66.17 ± 15.61) who underwent endoscopy for upper gastrointestinal bleeding were compared. The most common bleeding symptom was melena in both groups (50% vs 60%). Hospitalization in intensive care unit (47.5% vs 20%, P = 0.004) and need for mechanic ventilation (22.5% vs 5%, p = 0.006), use of corticosteroids were more common in coronavirus disease-2019 group (30% vs. 2.5%, p = 0.000). The need for erythrocyt replacement were not different between the groups [median (min - max) 1.5 (0 - 13) vs 0.5 (0 - 22), p = 0.397]. Use of low molecular weight heparin was statistically more common in coronavirus disease-2019 group (32.5% vs 5%, p=0.00). Time elapsed until the performance of endoscopy in terms of hours was significantly longer in coronavirus disease-2019 group (62.97 ± 84.59 vs. 21.85 ± 33.91, p = 0.006). The most common endoscopic finding was gastroduodenal ulcer in both groups. No significant differences were seen in terms of rebleeeding rates. Mortality rate was statistically higher in coronavirus disease-2019 group (37.5% vs 8.8%, p = 0.000). Conclusions: Until more precise guidelines for the management of gastrointestinal bleeding in COVID-19 patients are developed, a case-by-case decision should be made on whether to perform endoscopy and the timing of the procedure, after multidisciplinary assessments are made in terms of patient status, response to medical therapy, treatment resources, and assessment of risks.

Authors: Abdelhamid Mahmoud K. , A. Mossa Mahmoud , Hassan Ahmed A.
Published: April 2023

The article seeks to improve the dynamic performance of a standalone doubly fed induction generator (DFIG) which driven by a wind turbine, with the help of an effective control approach. The superiority of the designed predictive controller can be confirmed through evaluating the performance of the DFIG under other control algorithm, which is the model predictive direct torque control (MPDTC), model predictive current control (MPCC) as classic types of control. Firstly, the operating principles of the two controllers are described in details. After that, a comprehensive comparison is performed among the dynamic performances of the designed MPDTC, MPCC techniques and the predictive control strategy, so we can easily present the merits and deficiencies of each control scheme to be able to easily select the most appropriate algorithm to be utilized with the DFIG. The comparison is carried out in terms of system simplicity, dynamic response, ripples’ content, number of performed commutations and total harmonic distortion (THD). The results of the comparison prove the effectiveness and validation of our proposed predictive controller; as it achieves the system simplicity, its dynamic response is faster than that of MPDTC and MPCC, it presents a lower content of ripples compared to MPDTC and MPCC. Moreover, it can minimize the computational burden, remarkably. Furthermore, the numerical results are showing a marked reduction in the THD with a percentage of 2.23 % compared to MPDTC and 1.8 % compared to MPCC. For these reasons, it can be said that the formulated controller is the most convenient to be used with the DFIG to achieve the best dynamic performance.

Authors: EREN Hayati , GENÇ Selin , EVREN Bahri , ŞAHİN İbrahim
Published: April 2023

Objectives: T wave’s peak and end interval (Tp-e), Tp-e/QT ratio and Tp-e/QTc ratio are novel markers of ventricular repolarization and are associated with ventricular arrhythmias. Increased ventricular arrhythmia incidence is reported in patients with acromegaly. The purpose of this study is to evaluate ventricular repolarization using the Tp-e interval, Tp-e/QT ratio, and Tp-e/QTc ratio in patients with acromegaly.
Methods: Thirty-five patients with acromegaly were included in the study. The control group was consisted of forty-one subjects without acromegaly that having similar age, sex ratio and comorbidities. The Tp-e interval, Tp-e/QT ratio, Tp-e/QTc ratio, and other ventricular repolarization parameters of all patients were evaluated using electrocardiography.
Results: Tp-e interval, Tp-e/QT ratio and Tp-e/QTc ratio were significantly prolonged in patients with acromegaly compared to the control group. Furthermore, Tp-e interval, Tp-e/QT ratio, and Tp-e/QTc ratio showed a significant correlation with plasma GH levels and LVMI values.
Conclusions: Our study revealed that Tp-e interval, Tp-e/QT ratio, and Tp-e/QTc ratio are prolonged in patients with acromegaly. We believe that the Tp-e interval, Tp-e/QT ratio, and Tpe/QTc ratio can be used in the evaluation of increased cardiovascular risk in patients with acromegaly.

Peraturan Otoritas Jasa Keuangan No. 46/POJK.03/2015 menetapkan bahwa perhitungan Systemic Important Score (SIS) suatu bank menggunakan pembobotan yang sama besar untuk ketiga indikatornya: size, interconnectedness, dan complexity. Hal ini menafikan kemungkinan terdapatnya indikator yang berkontribusi lebih besar dalam menentukan struktur data komponen penilaian SIS dibandingkan indikator lainnya. Penelitian ini menawarkan alternatif sistem pembobotan dalam perhitungan nilai SIS tersebut. Sistem pembobotan tersebut adalah berdasarkan nilai eigenvectors dari Principal Component Analysis dengan melakukan standardisasi data terlebih dahulu. Hasil simulasi menunjukkan urutan tingkat sistemik kelompok perbankan di Indonesia dari yang paling tinggi adalah perbankan BUSN Devisa, Persero, Asing dan BPD, Campuran, dan BUSN Non Devisa.

Authors: Bjlani Vinod
Published: April 2023

Today’s digitally hyperconnected world, inching closer to mid-century climate-concern goals, is engaged in accomplishing sustainability targets. Industry and infrastructure have become as central to climate action as they have traditionally been to economic growth and social development. Commercial and public buildings in Smart cities contribute significantly to such progress. However, buildings also carry a negative impact on the environment and society, contributing through pollution, depletion of resources, carbon emissions, and high energy consumption. This paper describes the criticality of a sustainability performance information platform that brings together all the aspects of a sustainable building’s social, economic, and environmental qualities through intelligent management and operations. The author extends his belief in multi-dimensional sustainability by emphasizing the importance of people-participation through behavioral change and persuasive design in clean building technology to bring about a change for good. This paper is an attempt at a framework that will lead to greater collaborative efforts towards more intelligent, sustainable cities with interoperable green buildings.

The development of dairy farming proves to require technologies for rapid and non-destructive analysis of milk quality. It is noted that optical methods do not negatively aﬀect dairy products. It is noted that farms may get the desired technology by upgrading milking machines with a flow-through device for milk quality express analysis. (Research purpose) To study the eﬀect of upgrading the milking machine with a flow-through device for milk quality express analysis on the flow of the milk-air mixture in the milk hose. (Materials and methods) For this purpose the SolidWorks simulation modeling was used. Both the developed device and the simulation model are made in cylindrical geometry to ensure their compatibility with the milk hoses of 14 millimeters in diameter.  The measurement took into account the angular distribution of light scattered by milk flowing inside an optically transparent cylindrical glass tube. The flow of the milk-air mixture was aﬀected only by a change in the inner diameter of the milk tubes. (Results and discussion) It is noted that the simulation model demonstrates an increase in the flow rate of the milk-air mixture in the areas of flow transition between the milk hose and the fitting (to a smaller internal diameter), as well as between the fitting and the measuring chamber of the device (to a larger internal diameter). The mirror result is recorded at the flow outlet from the measuring chamber to the nozzle and the transition from the nozzle to the milk hose. (Conclusions) It is found that the use of the device results in a 14 percent increase in the average flow rate of 0.3-0.7 meters per second. It is determined that due to the incomplete filling of the milk hose during milking, the diﬀerence in the flow rates of the milk-air mixture before and when applying the device does not have any adverse impact on the milking machine operation. The feasibility of upgrading the milking machine with a flow-through device for milk quality express analysis is proved.

Fractions remain predominantly one of the most challenging topics to teach and learn. Brunei Darussalam is no exception, where a few local researches reported that students performed poorly in fraction topics. To understand this situation, this study focuses on pupils’ understanding in solving problems on fractions. Specifically, this study investigated Year 5 pupils’ conceptual and procedural performance on the addition of fractions. This study employed a quantitative research approach involving 572 primary school children. A test consisting of six carefully planned questions on fractions was used as the research instrument. The questions were divided into two sections to test pupils’ conceptual and procedural understanding laterally. The findings from this study revealed that children performed better in the procedural than in the conceptual questions. It can be concluded that most Year 5 pupils can correctly attempt the addition of fractions via procedural approach without understanding the essential concepts involved. Recommendation for future research was also discussed.

This study aims to investigate students’ prior knowledge as an obstacle when learning ratio and proportion concept. The study uses an interpretive paradigm which is part of Didactical Design Research. Eighth graders who had learned about ratio and proportion participated in this study. The analysis was carried out qualitatively based on the data from the students’ answers and interviews on their answers when solving ratio and proportion problems to identify learning obstacle, especially ontogenic obstacle regarding the students’ prior knowledge. The result of this study indicates that prior knowledge is one of the ontogenic obstacle in teaching and learning of ratio and proportion. It can be found from their learning experience in understanding the concept. In conclusion, investigating students' prior knowledge is essential for the effectiveness of teaching and learning of ratio and proportion. It is important to overcome ontogenic obstacles and to understand how to activate students’ prior knowledge using the right or appropriate methods when learning ratio and proportion.

The seismic activity observed in the vicinity of Ulaanbaatar (UB) city not only has been increased since 2005, but it is also organized, at least, on two perpendicular directions which determine two active faults: Emeelt fault (40 km long, situated 15 km NW of UB) and Hustai fault (80 km long, less than 30 km West of UB). The Songino fault (10 km long, situated 20 km West of UB) is located between Emeelt and Hustai fault. Their length and morphology indicate they can produce earthquakes of magnitude 6.5 to 7.5. Most of the Mongolian population (1.5 million over 3 million) is concentrated around UB city which is the main political and economical centre of the country. Hence, the study of seismic hazard is of first importance for the country. Since the last large earthquake, the fault geomorphology has been smoothed due to erosion processes and a low slip rate. The exact location of the fault is thus hidden in a several meter strip. In such a context, the Ground Penetrating Radar (GPR) method gives good and useful results and can help to characterize faults by identifying offsets of radar reflectionsand buried fluvial channel deposits. In order to image and characterize these faults, we have conducted many GPR campaigns in 2010, 2012 and 2013 over active areas around UB. In our study we present only some preliminary results of GPR measurements performed along the Songino fault (in 2013). The objective is to understand its geometry (dip, length, orientation) and the type of displacements and amplitude. In this survey we used 250 MHz, 500 MHz shielded antenna and RTA 50 MHz unshielded antenna and also used a differential GPS in order to measure the topography. One trench has been dug in Songino area.
