Background: The role of chest computed tomographic (CT) to diagnosis coronavirus disease-2019 (COVID-19) is still an open field to be explored. The aim of this study was to apply the decision tree (DT) model to predict critical or non-critical status of patients infected with COVID-19 based on available information on non-contrast CT scan.Method: This study was performed onpatients with COVID-19 who underwent chest CTscan atBaqiyatallahHospital, Tehran, Iran. In this retrospectivestudy, the medical records of 1078 patients with COVID-19 were evaluated. The classification and regression tree (CART) of decision treemodeland k-fold cross validation were used to predict the status of patients and to measure their sensitivity, specificity and area under curve (AUC).Results: Data included 169 critical cases and 909 non-critical cases. The bilateral distribution and multifocal lung involvement were165 (97.6%) and 766 (84.3%) in critical patients, respectively.According to DT model, total opacity score, age, lesion types and gender were statistically significant predictors incritical patients.Moreover, the results showed that the accuracy, sensitivity and specificity of the DT model were 93.3%, 72.8% and 97.1%, respectively.Conclusions: The presented algorithm demonstrates the factors affecting the patient's condition. In addition, this model has the potential characteristics for clinical applicationsand canalso identify high-risk subpopulations that need specific prevention.

Background: Domestic migration poses a challenge for China as migrants have little access to preventive healthcare services and are vulnerable to certain risks and diseases. This research sought to unveil and explore the determinant factors associated with health education utilization as a key aspect in basic public health services for migrants in Beijing, China.Methods: A sample of 863 inter-provincial migrants, 18 years old and above, was selected by three-stage stratified cluster sampling method in urban-rural fringe areas of Beijing during 2016 to 2017. Face-to-face structured interviews were conducted in the questionnaire survey. The effects of the explanatory variables on health education utilization from predisposing, enabling, health behaviors and need variables were used to demonstrate by Anderson health service utilization model. Results: The study revealed that 61.6% migrants desired to receive health education, while only 53.8% of them received in the past year. There were differences in the utilization and needs of health education among the migrants in different ages and genders. Many migrants desired to gain access to various types of health education information from the internet. Chi-square independence test lists such major determinant factors in migrants whole health education as age, "Hukou" registration system, marital status, education level, long-term residence plan in Beijing, one or more children in Beijing, employment status, housing source, average daily working time, exercises, health knowledge, smoking, self-rated health. The binary logistic regression indicates that the migrants with younger age, high education level, one or more children in Beijing, exercises and good self-rated health were more likely to receive whole health education. The results also show that average daily working time of enabling variables and exercise of health behavior variables were the strong and consistent determinants of three types of health education utilization, including communicable, non-communicable and occupational diseases.Conclusion: Gaps exist between the needs and utilization in health education and more attention should be given to the migrants with heavy workload and low education level. Feasible policies and measures, such as multiple health information channels, should be vigorously implemented to ensure equitable and easy access to health education for migrants.

Published: January 2021

Background Weight for length z-score (WLZ) <- 3 is currently used to define severe acute malnutrition (SAM) among infants. However, this approach has important limitations for infants younger than 6 months of age as WLZ cannot be calculated using WHO growth standards if infant length is <45 cm. Moreover, length for age z-score (LAZ) and weight for length z-score (WLZ) are least reliable measures, with high chances of variation, and less chances of detecting undernutrition in under 6 months infants. The objective of the current analysis was to compare WLZ with WAZ and LAZ in a cohort of Indian infants in predicting the deaths between 6 weeks and 6 months of age. Methods The data was from an individually randomized trial conducted in slums of Delhi, India in which infants’ weight and length were measured at 6 weeks of age (at the time of the first immunization visit). Vital status of the infants was documented from 6 weeks to 6 months of age. The sensitivity, specificity, positive and negative predictive values, and positive and negative likelihood ratios, and area under curve (AUC) were calculated for WAZ<-3, WLZ<-3, and LAZ<-3 for deaths between 6 weeks and 6 months of age. Results For deaths occurring between 6 weeks to 6 months of age, the specificity ranged between 85.9-95.9% for all three anthropometric indicators. However, the sensitivity was considerably higher for WAZ; it was 64.6 % for WAZ<-3, 39.1% for LAZ<-3, and 25.0% for WLZ<-3. WAZ <-3 had higher AUC (0.75; 95% CI: 0.68, 0.82) and hence, better discriminated deaths between 6 weeks and 6 months of age than WLZ<-3. The adjusted relative risk (RR 10.6, 95% CI 5.9, 18.9) and the population attributable fraction (PAF 57.9%, 95% CI 38.8, 71.0%) of mortality was highest for WAZ<-3. Conclusions We found WAZ<-3 at 6 weeks of age to be a better predictor of death in the 6 weeks to 6 months of life in comparison to WLZ<-3 and LAZ<-3 and propose that it should be considered to diagnose SAM in this age group.

Authors: Patel Mitesh , Aitken Devon , Xue Yunlin , Sockalingam Sanjeev , Simpson Alexander
Published: January 2021

BackgroundPhysicians are in a position of great influence to advocate for health equity. As such, it is important for physicians-in-training to develop the knowledge and skills necessary to fulfil this role. Although various undergraduate medical programs have implemented health advocacy training, they often lack experiential learning and physician involvement. These aspects are foundational to the Advocacy Mentorship Initiative (AMI) which utilizes cascading mentorship as a novel approach to advocacy training. Medical students develop advocacy competency as peer mentors to youth raised in at-risk environments, while also being mentored themselves by physician residents. We aim to determine whether there are specific advantages to utilizing cascading mentorship to facilitate the attainment of advocacy competencies in undergraduate medical education.MethodsMedical students participating in AMI between 2017 to 2020 completed pre- and post-exposure questionnaires. Questionnaires assessed confidence in advocacy-related skills and knowledge of youth advocacy concepts, as well as learning goals, skills gained, benefits of AMI and resident mentors, and impact on future career. Sign tests were utilized to analyze quantitative results, and content analysis was used for open-ended responses. A triangulation protocol was also utilized.ResultsFifty mentors participated, 24 (48%) of which completed both pre- and post-exposure questionnaires. Participants gained confidence in advocacy-related skills (p<0.05) such as working with vulnerable populations and advocating for medical and non-medical needs. They also reported significant improvements (p<0.01) in their understanding of social determinants of health and concepts related to children’s health and development. Content analysis showed that participants built meaningful relationships with mentees in which they learned about social determinants of health, youth advocacy, and developed various advocacy-related skills. Participants greatly valued mentorship by residents, identifying benefits such as support and advice regarding relations with at-risk youth, and career mentorship. AMI impacted participants’ career trajectories in terms of interest in working with youth, psychiatry, and advocacy.ConclusionsAMI offers a unique method of advocacy training through cascading mentorship that engages medical students both as mentors to at-risk youth and mentees to resident physicians. Through cascading mentorship, medical students advance in their advocacy-related skills and understanding of social determinants of health.

Published: January 2021

Background: Recent research has pointed out the important roles of epigenetic modifications in the development and persistence of allergic rhinitis (AR), especially in relation to DNA methylation of disease-associated genes. We investigated whether AR susceptibility genes were epigenetically regulated, and whether methylation modulation of these genes in response to early-life environment could be a molecular mechanism underlying the risk for AR onset in a cohort of children aged 3-6 years in China.Methods: Peripheral blood mononuclear cell (PBMC) samples were collected from 130 children patients, aged 3-6 years and diagnosed with AR; and 154 matched controls to detect promoter methylation in 25 AR susceptibility genes with the MethylTarget approach. Methylation levels were compared for each CpG site, each amplified region, and each gene. In addition, the relationship among DNA methylation, early-life environmental risk factors and AR onset were assessed. Results: Maternal allergic history (P = 0.0390) and pet exposure (P = 0.0339) were significantly associated with increased AR risk. Differential methylation analyses were successfully performed for 507 CpG sites, 34 amplified regions and 17 genes and significant hypomethylation was observed in the promoter region of ADAM33 in AR patients [multiple test-corrected (FDR) P-value < 0.05]. Spearman correlation analysis revealed that the hypomethylation of ADAM33 was significantly associated with higher eosinophil counts (Spearman's ρ: -0.187, P-value = 0.037). According to the results of the multiple regression analysis, after adjusting for cofounders, the interaction of early-life pet exposure with methylation level of ADAM33 increased the risk for AR onset 1.423 times more in children (95% CI = 0.0290-4.109, P-value = 0.005). Conclusion: This study provides evidence that early-life pet exposure and low methylation level of ADAM33 increase AR risk in children, and the interaction between pet exposure and methylation level of ADAM33 may play an important role in the development of AR.

BACKGROUND: Less than 19% of those needing tuberculosis (TB) preventive treatment complete it, due to losses in several steps of the cascade of care for latent TB infection. A cluster randomized trial of a programmatic public health intervention to improve management of latent TB infection in household contacts was conducted in Rio de Janeiro. Interventions included contact registry, initial and in-service training, and a TB booklet. We conducted a follow-up study starting one month after the conclusion of this trial, to measure the effect of interventions implemented, and to identify remaining barriers and facilitators to latent TB infection treatment, from different perspectives.METHODS: In two health clinics in Rio de Janeiro that received the interventions in the trial, data for the latent TB infection cascade of care for household contacts was collected over a five-month period. The number of household contacts initiating treatment per 100 index-TB patients was compared with the cascade of care data obtained before and during the intervention trial. Semi-structured open-ended questionnaires were administered to healthcare workers, household contacts and index-TB patients regarding knowledge and perceptions about TB and study interventions. RESULTS: In this follow-up study, 184 household contacts per 100 index-TB patients were identified. When compared to the intervention period, there were 65 fewer household contacts per 100 index-TB patients, (95% CI -115, -15) but the number starting latent TB infection treatment was sustained (difference 2, 95% CI -8,5). A total of 31 index-TB patients, 22 household contacts and 19 health care workers were interviewed. Among index-TB patients, 61% said all their household contacts had been tested for latent TB infection. All health care workers said it was very important to test household contacts, and 95% mentioned that possessing correct knowledge on the benefits of latent TB infection treatment was the main facilitator to enable them to recommend this treatment.CONCLUSION: In this follow-up study, we observed a sustained effect of interventions to strengthen the latent TB infection cascade of care on increasing the number of household contacts starting latent TB infection treatment.

Published: January 2021

Background: In developing countries, malnutrition in children and developmental delays are two major challenges for public health. To achieve the vision of the Sustainable Development Goals in the broader perspective of child health, an early identification of developmental delays and timely intervention is crucial. The aim of this study is to assess the prevalence of suspected developmental delay and their predictors in under-five uncomplicated severe acute malnourished children in rural areas of Pakistan.Methods: A multicenter cross-sectional study has been conducted among 185 uncomplicated severe acute malnourished children. We screened 6–59 months aged children for their nutritional status and clinical complications. Children fulfilling the inclusion criteria underwent the Denver Development Screening Tool II (DDSTII). The global developmental profile of children was calculated according to established protocols of DDSTII based on four important domains of development: personal and social behaviour, language, gross motor adaptive and fine motor adaptive skills. A pretested structured questionnaire on socio-demographic and nutritional factors was used for assessing predictors of developmental delay, which were analysed in a multivariate logistic regression model.Results: Out of 177 severe acute malnourished children, 69 (38.9%) had normal global development and 108 (61.1%) had delayed global development. Significant associations with global development delay were found for lower aged children (6-24 months vs. 25-59 month; AOR=4.53, 95% CI: 1.56–13.10, p<0.01), not exclusively breastfeed children (AOR=3.07, 95% CI: 1.24–7.56, p=0.01), and a history of contact with tuberculosis smear positive adult (AOR=2.67, 95% CI: 1.30–5.49, p<0.01).Conclusion: With about two thirds of study participants showing delayed or unstable global development, there is a high prevalence of suspected developmental delay among under-five uncomplicated severe acute malnourished children in rural areas Pakistan. Particularly children in their first two years of life with insufficient breastfeeding are at high risk. This emphasizes the need for providing adequate infrastructure and information to parents in remote areas.

Published: January 2021

Background The Sahrawi people fled their homes in 1975 as the conflict in Western Sahara escalated and settled down near Tindouf, Algeria, where they still live. High prevalence of overweight and obesity and type 2 diabetes had been found in this protracted refugee setting. Scaling up national policy efforts to promote physical activity (PA) is critical to reducing the prevalence of noncommunicable diseases (NCDs) in the near future. One possible barrier to the inclusion of PA in NCD prevention strategies is the lack of research on PA level, which may reduce political support and policy development for PA. Thus, the aim of this study was to investigate the PA level among adults living in Sahrawi refugee camps and socioeconomic factors associated with PA. Methods A cross-sectional survey was carried out in 2014 in five refugee camps near Tindouf, Algeria. A total of 180 women and 175 men were included. PA was measured using the international physical activity questionnaire short form (IPAQ-SF). Results There was a large amount of variance in reported PA for both genders, ranging from 10 min of total PA per week to above 40 hours. Forty-three percent of the participants had a low PA level (defined as not meeting the PA recommendations of 150 min of moderate to vigorous PA per day). The chi-square test of independence showed that males, those aged ≥ 60 years and people with higher education were more likely to be in the low PA level category. No significant relationship was found between PA level and BMI status. Most of the participants thought that engaging in PA would be wise, valuable, right and good but thought to a lesser degree that PA would be easy, comfortable and interesting. Conclusions Almost half of the participants were categorised as insufficiently physically active, however, most of the Sahrawi refugees express a positive attitude towards PA. PA is a low-cost approach to reducing deaths and NCDs, government initiatives to increase PA levels in refugee camps are advised.

Published: January 2021

Background: The purpose of this study is to elucidate the association between peripherally inserted central venous catheter (PICC) in upper extremities and lower extremity deep venous thrombosis (LEDVT) by observing the changes in D-dimer.Methods: This was a retrospective cohort study of 3452 patients (104 inserted with PICCs and 3348 without PICC) enrolled at the neurology department from April 1, 2017 to April 1, 2020. The patients underwent color Doppler ultrasound (CDU) and D-dimer examinations. LEDVT-related factors and the D-dimer value were analyzed before and after PICC insertion. The predictive value of D-dimer for LEDVT was also evaluated. Results: Univariate logistic regression analysis showed that PICC insertion increased the risk of LEDVT by 9 times and promoted the increase of D-dimer by 5 times. After risk adjustment, multivariate logistic regression analysis showed that PICC insertion tripled the risk of LEDVT and doubled the risk of D-dimer increase. The concentration of D-dimer was significantly increased after PICC insertion. D-dimer was unsuitable for excluding venous thrombosis in patients inserted with PICCs.Conclusion: PICC insertion increases the level of D-dimer and the risk of LEDVT. The risks of venous thrombosis need to be assessed in patients inserted with PICCs to ensure the expected clinical outcomes.
Medienpädagogische Professionalisierung von Lehrpersonen in einer mediatisierten Welt
Authors: Dertinger Andreas
Published: January 2021

Der Metaprozess der tiefgreifenden Mediatisierung führt zu neuen und veränderten Anforderungen an das pädagogische Medienhandeln von Lehrkräften. Um die Qualität des unterrichtlichen Medieneinsatzes zum Lernen mit und über Medien sicherzustellen, werden sowohl im pädagogischen Fachdiskurs als auch auf bildungspolitischer Ebene Kompetenzerwartungen an die professionelle Arbeit von Lehrpersonen formuliert. Empirische Ergebnisse zeigen, dass diese Erwartungen nicht mit dem Medieneinsatz von Lehrpersonen im Unterricht hinsichtlich Umfang und Qualität übereinstimmen (Drossel et al. 2019; Schaumburg et al. 2019). Die Frage, wie ein professionelles und pädagogisch angemessenes Medienhandeln im Unterricht befördert werden kann, wird im medienpädagogischen Diskurs unter vielfältigen Perspektiven thematisiert. Studien zum medialen Habitus zeigen, dass das implizite Wissen einen bedeutenden Einfluss auf das pädagogische Medienhandeln hat (Biermann 2009; Kommer 2010). Bei einer genaueren Betrachtung dieses Themenbereichs entstehen auf theoretischer Ebene allerdings Fragen zur Konzeption des Habitus und des impliziten Wissens. Insbesondere die Frage, wie das Konstrukt des Habitus mit den gesellschaftlichen Veränderungen einer tiefgreifenden Mediatisierung in Beziehung gesetzt werden kann, ist noch ungeklärt. Der vorliegende Artikel widmet sich dieser Fragestellung auf einer theoretischen Ebene, die einen Ausgangspunkt für weitere Diskussionen und für die empirische Forschung darstellen soll.
Die Dualität von Kompetenz in tiefgreifend mediatisierten Welten
Authors: Mehlan Henriette , Holten Jörg
Published: January 2021

In tiefgreifend mediatisierten Welten ist Medienkompetenz ein Schlüsselbegriff. Für Politik, Wirtschaft und Bildung ebenso wie für Wissenschaft. Das Konzept Medienkompetenz und vor allem sein Gehalt für die Wissenschaft sind aber umstritten. Innerhalb des medienpädagogischen Diskurses hat es unterschiedliche Wendungen erfahren, die zuletzt dazu führten, dass es ganz abgelehnt wurde. Der Beitrag zeichnet die definitorischen Wendungen nach und legt schliesslich ein eigenes Verständnis vor. Dabei werden Kompetenz und Performanz im Anschluss an Giddens als zwei Dimensionen unterschieden (Dualität), die sich gegenseitig bedingen und reproduzieren. Ferner wird eine zweite Unterscheidung eingeführt, die zwischen Wirklichkeitskonstruktionen erster und zweiter Ordnung differenziert. Durch diese Unterscheidungen ist es möglich, bisher implizite Denkweisen über Kompetenz sichtbar zu machen, ohne dabei einer Seite der Dualität von Kompetenz ihre Berechtigung abzusprechen. Aus der vorgeschlagenen Kompetenzdefinition folgt schliesslich, dass das Nachdenken über Medienkompetenz nicht ausschliesslich Aufschlüsselung von einzelnen, vor allem medienbezogenen Kompetenzen sein kann, sondern vielmehr die Frage nach der Dualität von Kompetenz in tiefgreifend mediatisierten Welten impliziert.
Gelingensbedingungen für den Einsatz digitaler Medien
Authors: Koppel Ilka
Published: January 2021

Ausgehend von einer tiefgreifenden Mediatisierung der Gesellschaft (vgl. z. B. Couldry und Hepp 2016) werden für die Teilhabe an der Gesellschaft neben der literalen und der mathematischen Grundbildung nun auch eine digitale Grundbildung notwendig (BMBF und KMK 2016; Tröster und Schrader 2016). Entsprechend wird eine stärkere Einbindung digitaler Technologien in der Erwachsenenbildung (European Comission 2015; Helbig und Hofhues 2018; Pietraß 2015) sowie eine Weiterbildungsoffensive gefordert und auch umgesetzt (vgl. z. B. Staatsministerium Baden-Württemberg). Auch wenn der Bedarf an digitaler Grundbildung hoch ist, wird der Erwachsenenbildung gegenüber computerbasierten Lernprozessen und deren konzeptionelle Einbindung eine distanzierte Einstellung (Arnold 2014, 157; Hartung-Griemberg 2017) postuliert. Insbesondere ist dies im Bereich der Alphabetisierung der Fall (Helbig und Hofhues 2018, 12). Aber gerade diese Zielgruppe kann besonders von dem Einsatz digitaler Medien profitieren (vgl. z. B. Koppel 2017; Wolf und Koppel 2017). Im Bereich der Alphabetisierung und Grundbildung existieren allerdings bisher kaum Erkenntnisse darüber, welche Faktoren zu einem gelingenden Einsatz digitaler Medien beitragen. Ziel des hier vorgestellten Projektes «Geco» ist es daher, mittels leitfadengestützter Interviews Gelingensbedingungen für den Einsatz computerbasierter Lernprogramme in der Alphabetisierung und Grundbildung zu identifizieren. Die Ergebnisse der Studie/des Projekts werden im Folgenden vorgestellt.
Die vernetzte Schulklasse

Published: January 2021

Wie organisieren Schülerinnen und Schüler ihre Lernaktivitäten in einer Welt, die von tiefgreifender Mediatisierung geprägt ist? Welche Rolle spielen Kommunikationsplattformen und ihre vielfältigen Möglichkeiten der Vernetzung ausserhalb der Schule für Hausaufgaben und häusliche Lernaktivitäten? Diese Fragen zielen auf das Medienhandeln als konstruierenden und konstruierten Kontext. Versteht man Schulklassen als kommunikative Figurationen, so lässt sich diese spezifische Akteurskonstellation und ihr Repertoire an Medien untersuchen; dieses Repertoire strukturiert Kommunikation einerseits und befähigt andererseits zur individuellen und kollektiven Aushandlung des thematischen Rahmens. Innerhalb dieser Formationen lassen sich Handlungs- und Wirksamkeitsräume identifizieren, die Bildungspotentiale beinhalten. Der folgende Beitrag möchte anhand ausgewählter Beispiele aus einer Studie im Mixed-Methods Design Licht in ausserschulische Lernaktivitäten bringen. Dabei werden Ansätze der Sozialen Netzwerkanalyse (SNA) mit interpretativen Methoden der Datenauswertung kombiniert. Ergebnis dieser Methodenkombination ist eine Darstellungsform zur Rekonstruktion des Zusammenspiels zwischen individuellem und kollektivem Medienhandeln in Bezug auf Lernaktivitäten.

Tablet-Based Apps for Phonics and Phonological Awareness: Protocol for Evidence-Based Appraisal of Content, Quality, and Usability
Authors: Furlong Lisa , Serry Tanya , Erickson Shane , Morris Meg E
Published: January 2021

Background

The use of mobile apps to manage and promote health is becoming increasingly popular. Mobile apps are gaining popularity particularly in educational and interventional settings owing to their perceived advantages including support for and engagement of individuals with reading difficulties. In the context of COVID-19, the need for technology-based tools has increased. For practitioners and educators who wish to use apps in their practice or recommend apps to individuals with reading difficulties, it is challenging to identify high-quality apps in app stores.

Objective

This protocol describes a systematic search, selection, and appraisal process for tablet apps targeting phonics knowledge and phonological awareness skills. This protocol aimed to (1) provide a systematic method for identifying tablet apps targeting phonics knowledge and phonological awareness skills in the Google Play Store and Apple’s App Store and (2) describe an evidence-based approach for quality appraisal of these apps by using structured tools.

Methods

This protocol describes an evidence-based method guided by the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) framework to systematically search, select, and appraise apps targeting phonics knowledge and phonological awareness skills, present in Google Play and the App Store. We intend to perform a systematic and comprehensive search and a 2-step process for screening: (1) broad screening (app titles) and (2) narrow screening (marketing descriptions). Quality appraisal of the included apps will involve two structured appraisal tools: (1) the Mobile Application Rating Scale and (2) the Appraising Apps for Reading Checklist.

Results

This method will help determine the number of apps targeting phonics knowledge and phonological awareness, present on the Android and iOS platforms. The content, quality, and usability of these apps will be determined using structured appraisal tools. We have planned to conduct searches on Google Play and the App Store in January-March 2021; broad and focused screening, from April 2021; and data extraction and quality appraisal in October 2021.

Conclusions

This protocol provides a basis for locating and evaluating apps targeting phonics knowledge and phonological awareness skills. This protocol will support practitioners, educators, and families to make informed decisions when purchasing apps for instructional use.

Published: January 2021

Population changes of the Russians and other Slavs are an important original indicator of demographic, economic, political, and cultural analysis of over 300 million Slavic inhabitants in Central, Eastern, and Southeastern Europe. The indicators are conditioned by the large number of people executed in World War I and World War II, significant economic migrations, the disintegration of the Soviet Union, Yugoslavia, and Czechoslovakia. Utilizing data from official reports, the authors proceed to analyze the demographic tendencies in order to find out the relationship between modern demographic trends and political and economic events over the past years. The results showed that economic and demographic stagnation, which favor religious and national (ethnic) ambivalence, influence the strengthening of groups ethnically isolated or religiously differentiated in the observed macroregions of Eurasia. The contemporary challenges of modern society in terms of global politics (e.g. terrorism and migrations) will be more pronounced and turbulent in these areas.

The groundwater resources from open dug wells are the ultimate and inevitable drinking water source in Chennai municipality. These are of shallow depth of 8 to 10m with a static water depth range of 30 to 75 m. This study's objective was to assess silica (in the form of Silicon Dioxide, SiO2) in groundwater and to establish their baseline concentration. Twelve wells were monitored in the study area, in some parameters, namely: Chloride (Cl-), Total Dissolved Solids (TDS), pH, Electrical Conductivity (EC), and SiO2. We examined the existing relationship between silica and other measured water quality parameters (Cl-, pH, TDS, and EC) using Spearman correlation matrix analysis in SPSS software and Normalized Difference Dispersal Index (NDDI) in Simplex Numerix software that was applied to identify the hotspots of SiO2. The water pH ranges from 8.09 to 8.37 (slightly alkaline) with an appreciable amount of TDS (730.50 to 1294.50 ppm). The groundwater also contains abundant silica (15.50 to 24.0 ppm), Cl- (106 to 438 ppm), and EC (759.50 to 1837.50 µS/cm). Further, a geostatistical tool was used to derive NDDI map of groundwater quality parameters and quantified site-specific variations in parameters, namely SiO2, Cl-, pH, TDS, and EC values. Average NDDI value enrichment was exhibited by SiO2 (0.09, ≈ 0.1) it reﬂects accretion, while average NDDI values of Cl- (–0.09, ≈–0.1), EC (–0.04), TDS (–0.03), and pH (–0.02), it outlined that by dilution in particular groundwater parameter.

The popular scientific journal “Khan Tenger” is an important and valuable source for the study of the folklore of the Oirats of the PRC. This periodical is devoted to the study of the culture and language of the Oirats living in the PRC (XUAR PRC, Inner Mongolia Autonomous Region) was published in the period from 1981 to 1993 by the Xinjiang People’s Publishing House (Šinǰiyang-giyin aradiyin keble-liyin xorō) in Urumqi city. The journal was published four times a year in the Oirat “clear script” and is a unique collection of the best examples of oral folk art of the Oirats of the XUAR of the PRC. The article examines some genres of non-fairytale prose of the Oirats of the XUAR of the PRC, recorded in the Khan Tenger journal. Non-fairytale prose is the richest heritage which contains the ancient beliefs of ancestors, moral norms and historical memory of the Oirats. A large number of cosmogonic myths about the creation of the world, the origin of the earth, sky, stars, sun, moon, as well as etiological myths about the origin and characteristics of animals, birds, insects, plants, and natural phenomena are published on the pages of the Khan Tenger journal. Legends and traditions reproduce the historical reality in the refraction of people’s mind through their vision and assessment. They have absorbed archaic elements that characterize the mythological consciousness and the ancient views of distant ancestors. The publication of texts of myths, legends and traditions will help to fill in the “white spots” in the genre system of the folklore of the Oirats, will help to study the spiritual culture of the Mongol-speaking peoples.
