Authors: Alfageme-González María Begoña , Díaz-Serrano José
Published: February 2020

Las teorías de los estilos de enseñanza-aprendizaje ayudan al docente a desarrollar su aspecto personal y profesional centradas en lo cognitivo y el aprendizaje. Este trabajo analiza el estilo de enseñanza del profesorado de Geografía e Historia de Educación Secundaria y sus prácticas educativas, diagnosticando el estilo docente y describiéndolo. El estudio adopta un enfoque mixto; es decir, combina un diseño cuantitativo descriptivo-comparativo con uno cualitativo de carácter fenomenológico. Así, aunque en este colectivo las puntuaciones de los estilos de enseñanza están bastante equilibradas, predominan ligeramente los estilos formal y funcional. Sin embargo, parece que las prácticas educativas del profesorado tienen como principal referente el trabajo en el centro educativo y en el equipo docente, por encima del estilo de enseñanza predominante en el docente, por tanto, se configuran como el mayor constitutivo en el proceso de la identidad profesional docente.

﻿Objectives: The purpose of the study is to determine the impacts of the prenatal classes on pregnant women while determining the type of delivery and coping with pain during delivery. Methods: This study is descriptive. It involves analysis of 247 participants that were selected as samples from a known population of 653 pregnant women who participated in prenatal classes of our hospital. The prenatal classes took place for 3 weeks and 16 hours in total. They filled the forms regarding the class activities before and after the class. The data were evaluated by using SPSS 16.0 packaged software. Results: The mean age of the pregnant women was 27.50 ± 4.60 years. The women, who had their first pregnancy, were 73.3%. Before the class, 62.8% declared that they were planning to have a vaginal delivery. The ones, who stated that they were afraid of pain, were 78.9%. In interviews after the classes, 89.5% of the participants stated that the classes affected their choice of delivery type. The rate of participants that found classes relieving for their anxiety and concerns was 94.70%. The rate of participants that had a vaginal delivery was 81.80%. The influence of the prenatal classes while determining the type of delivery was statistically significant. (p < 0.001 by Mc Nemar test). Conclusions: Participation with the prenatal class removes the anxiety of the pregnant women, encourages them to have vaginal delivery and contributes to decreasing the rate of cesarean sections.

Authors: Barabanov A.V. , Serebryanskiy S.A.
Published: February 2020

The paper considers a complex criterion for assessing the characteristics of the radio-transparent fairing of the supersonic aircraft onboard radar. The algorithm for research performing which will allow to establish interrelation between radio, aerodynamic and the main geometrical characteristics of radio-transparent nose fairings, such as lengthening of the forward part of a fuselage, an angle of inclination of a tangent to a curve forming a body of rotation and a discriminant of a curve generator is developed. The process of forming the geometric shape of the onboard radar radio-transparent fairing of a supersonic aircraft is based on two interrelated processes: providing the appropriate radio technical characteristics of the fairing to meet the requirements for the range of the aircraft radar detection and minimizing the drag of the nose of the fuselage. Research following the proposed algorithm allows forming technical recommendations for the selecting rational geometric parameters of onboard radar radio-transparent fairing of a supersonic aircraft at the early stages of aircraft design.

Present investigation was undertaken to detect and characterize the PPR virus from different clinical tissue samples of 14 sheep and 17 goats with respiratory disease from Maharashtra, India. All animals were tested by Sandwich ELISA, of which 70.96% were found positive carrying high PPR virus inwhich 12 were sheep and 10 were goats respectively. For confirmation of PPR, molecular detection was performed with RT-PCR using F gene and N gene specific primers. Intestine samples accounted for highest percent positivity (75%) followed by blood (66.66%) and lymph node (62.5%) for presence of virus. Unusually higher positivity was observed in heart, liver and Kidney (60%, each) than normal predilection sites such as lungs (57.84%) and spleen (50%). While nasal swabs and blood were individually processed with F gene and N gene specific PCR, the triturated organs were pooled for processing into ‘Sample A’ comprised of heart, kidney, liver and intestine combined together and ‘Sample B’ comprising of lung, spleen and lymph nodes combined for the molecular detection of PPR yielding the products each of 372bp and 463bp sizes, respectively. Out of total 40 samples tested, 09/12 each from both sample A and B, while 02/10 nasal swabs resulted positive, respectively and all 06 blood samples remained negative. (F as well as N gene PCR methods were found best suitable for detection of PPR virus from tissue samples of small ruminants).

Authors: Ghorbani E , Azar A Motallebi , Bolandnazar S
Published: February 2020

Diversity of 9 local Iranian genotypes of melon was studied based on 28 quantitative and qualitative agro-morphological traits, using multivariate statistical methods. Analysis of variance showed significant differences between genotypes for all quantitative traits. However, the studied melon genotypes were previously clustered in two main groups of inodorous and cantalopensis, cluster analysis classified them in four different groups based on all traits, in particular outlaying Shadegani genotype from Inodorous group. Clustering was also supported by principal components analysis (PCA). The first two PCs contributed 60% of the total variability and demonstrated variations mainly on the basis of yield related traits including fruit number, day to flower, day to harvest, fruit weight, fruit length and other distinctive traits such as rind pattern, peduncle attachment strength, fruit firmness and aroma. Accordingly, agro-morphological traits could be used for variation studies in melons and results might be useful for improving breeding programs.

The digital transformation of the economy and society prompts the renewal of methods in occupational health as well. There are outlined fundamentals of the draft revision of the “Guidelines for the Assessment of Occupational Risk to Employee Health. Organizational and methodological foundations, principles and criteria for the assessment». R 2.2.1766-03. The draft contains methods of occupational risk (OR) assessment supplied with information materials and software for working on the Internet in real-time. Algorithms and models for calculating the probability of impairment of health according to data of the Special Assessment of Working Conditions (SAWC) as well as causation algorithms - work-relatedness assessment according to data of periodic medical examinations (PME) for the validity of risk assessment from the standpoint of evidence-based medicine are presented. There are set out methods for calculating the probability of the formation of occupational diseases (OD) of the main nosological forms from the exposure of noise, hand-arm and whole-body vibration, heat and cool microclimate, fibrogenic dusts, physical labor (local, regional and general loads), strenuous work, standing work with the likelihood of varicose lower veins limbs, multi-factor exposure and low-back pain. Risk assessments for the reproductive health of workers are also discussed. The models are based on the documents of the WHO, ILO, ISO, domestic and foreign literature data that meet the principles of evidence-based medicine. The problems of work-related diseases (WRD) - the concept of WHO (1987) -basics of etiology, qualitative and quantitative criteria for causation, models of consensus and evidence-based medicine, as well as projects for integrated work on the detection systems for WRD in the European Union countries are considered. Single-digit indices of working conditions and health problems, moral harm caused to an employee suffering from OD or WRD. Hygienic recommendations to employers on OR management, prevention priorities, the role of personal protection equipment, the basics of corporate health promotion programs, and ethical and economic aspects are described. The calculation methods are provided by the software of the electronic online reference book “Occupational Risk” (URL: http://medtrud.com/) in order to ensure evidence-based decisions of hygienists. In conclusion, a turning point in occupational health is noted: a decrease in the detection of traditional ODs without compensation by the number of OD and WRD from new technologies, materials and risk factors; this problem requires urgent action.

Introduction. The document analyzes the current state of issues of medical exposure of the population using methods of radiation diagnostics. Purpose of research is thr development of approaches to optimization of radiation doses to patients, taking into account radio-succeptibility and radioresistance of different age groups exposed to medical irradiation (MI), forming radiation doses and risks of induction of long-term stochastic effects in these groups. Material and methods. Analysis of factors affecting the formation of dose load approaches to the study of x-ray diagnostics at the present stage. Results. The paper gives a detailed review of modern scientific views on the effect of low doses of radiation, identifies controversial aspects of this problem, including the threshold of stochastic effects. The analysis of the main factors of MI dose formation is carried out. It is concluded that it is formed mainly in the field of diagnostic irradiation, while the restriction (1 mSv) applies only to preventive irradiation. This leads to a lack of systematic approaches to the reasonable limitation, optimization, and justification of diagnostic radiation procedures. The significant part of the dose load was shown to be formed due to unreasonable or erroneous directions to the study. Medical exposure is significantly different from other types - man-made and natural, and the risk of medical exposure competes with the risk of failure of radiation diagnostics. A number of measures aimed at reasonable limitation of medical exposure and reduction of risks of stochastic effects while ensuring high quality of diagnostics are proposed. The proposals are based on the provision to reduce radiogenic risks with increasing age. It is also proposed to develop “practical thresholds” of medical exposure for different age groups. Conclusion. The necessity of correction and approaches detailing on justification and purpose of studies in x-ray diagnostics, taking into account features of irradiated contingents, development on this basis of “practical thresholds” of MI at a priority of quality of clinical diagnostics is established.

Introduction. The element composition of blood is the most relevant index in biomonitoring studies to assess public health risks. The authors determined the elemental composition of the whole blood in 100 the unexposed children residing in the West Ural region using the ICP-MS method and standard biomonitoring methodology of the World Health Organization (WHO). This study allows for improving the comparability and reliability of the analysis results, as well as to supplement information on human biomonitoring for various territories of the Russian Federation. A comparative assessment of the contents of vanadium, chromium, manganese, nickel, copper, zinc, arsenic, selenium, strontium, cadmium, thallium and lead with reference concentrations used in national programs for human biomonitoring (BMC) of European countries and the United States was made. Material and methods. The authors determined mass concentrations of V, Cr, Mn, Ni, Cu, Zn, As, Se, Sr, Cd, Tl, and Pb by ICP-MS in conformity with Methodical Guidelines 4.1. 3230-14 (FR.1.31.2014.17064) developed by the authors. The article contains setting parameters for quadrupole mass spectrometer with inductively coupled plasma (Agilent 7500cx), the optimal sample preparation scheme for eliminating the “matrix” effect. The operating mode of the mass spectrometer with a response/collision cell to mitigate interferences and the choice of internal standards is justified. The sample preparation of whole blood was made by acid dissolution followed by centrifugation. The detection limits (LOD) for each element are calculated. Results. The results are presented in the form of basic statistics: minimum and maximum values, arithmetic mean (AM), geometric mean (GM), 5, 50, 95 percentiles and interpreted in accordance with modern international requirements. The geometric mean (GM) of element content in blood amounted to 0.11 µg/l (V); 5.34 µg/l (Cr); 13.1 µg/l (Mn); 3.15 µg/l (Ni); 854.7 µg/l (Сu); 4655.0 µg/l (Zn); 0.13 µg/l (As); 84.97 µg/l (Se); 28.0 µg/l (Sr); 0.28 µg/l (Сd); 0.05 µg/l (Tl); 18.63 µg/l (Pb). The validity of the results was confirmed by means of SERONORM TM Whole Blood L2 standard samples (Norway). The results of the study relied upon the 95 percentile (P95) can be used as approximate reference data as a basis for assessing the risk associated with exposure to metals. Conclusion. Regional differences from levels found in other Europe countries (Italy, Norway) and the USA included higher concentrations of Mn, Cr and Ni and lower levels of Cu, Zn and Se in blood of children in the rural areas of the West Ural region. The optimal method for determining the content of essential and toxic elements in blood by mass spectrometry with inductively coupled plasma has been substantiated and recommended for practical use (MG 4.1. 3230-14, FR.1.31.2014.17064).

Introduction. Helicobacter pylori (Hр) is considered usually as one of the factors in the development of gastritis, peptic ulcer, and gastric cancer, and at the same time as protection from asthma, diabetes type II, and obesity. This study was carried out with a goal to evaluate possible linkage between the levels of circulating anti-Hp antibodies and inflammatory markers - IL-6, IL-8 and malonic dialdehyde (MDA) - in cross-sectional study of Moscow adults. Material and Methods. Serum samples of Moscow working-aged residents (both gender, N=252) were used for evaluation of antibodies to lysate Hp antigen/recombinant CagA and cytokines IL-6, IL-8 with corresponding ELISA kits. MDA was determined by reaction with thiobarbituric acid. Results. Standard correlation analysis didn’t reveal any significant association between the levels of circulating antibodies against the applied commercial antigens and the levels of IL-6, IL-8 and MDA. Nevertheless, two parallel branches of the experimental points in seropositive area of anti-CagA/IL-8 scatterplot (but not for IL-6 and MDA variables) were clearly seen and correspond to two maximums at bimodal anti-CagA distribution. The data obtained are consistent with typical for CagA outstrip in IL-8 induction and testify the existence of two human genotypes having ~2-fold difference in antibody response but the same reactivity of CagA - IL-8 axis. Since CagA-positive IL-8 levels are of one order with CagA-negative ones (from another organs) and signs of concomitant oxidative stress were not revealed, the data obtained can be interpreted equally as early pathologic or actual symbiotic events. Conclusion. Quantitative assessment of circulating anti-Hp antibodies, together with more detail mathematical analysis, will increase contributions of population studies to investigation of equilibrium between Hp and human organisms.

Introduction. Low quality of endoscope treatment is one of the main risk factors for HAI during endoscopic manipulations. Special equipment is widely used to increase quality and safety of healthcare during the treatment of flexible endoscope. However, to confirm the efficiency of such equipment it is necessary to carry out laboratory experimental studies. Material and methods. A prototype model of domestically developed Device intended for carrying out the stages of final cleaning and high-level disinfection (HLD) of flexible endoscopes was used during research, utilizing the samples of agents with various active ingredients. Flexible endoscopes were used as testing devices. Donor blood was utilized for imitation of organic contamination. Mycobacterium terrae test microorganism culture was used for artificial contamination of testing devices. Results. As a result of studying the efficiency of final cleaning and HLD of flexible endoscopes in the Device after them being used once, negative azopyram samples were identified in all endoscope swabs; also, no growth of test microorganism was registered. During the studies of HLD efficiency in case of multiple use of functional solutions treatment efficiency was registered for 6-8 cycles. After the 12th treatment cycle characteristic growth of test microorganism is observed in the swabs. Efficiency of endoscopes’ decontamination in case of multiple use of a disinfectant based on peroxyacetic acid was confirmed during a work shift after 8 cycles; the decrease of disinfecting agent (DA) concentration by more than 10 times was registered during the shelf life of the functional solution on day 5. Conclusions. Studies indicate the necessity to research the efficiency of devices’ use to determine the conditions ensuring efficiency and safety of healthcare during endoscopic interventions.

This article presents a clinical case of a 62-year-old man with a long history of coronary heart disease and smoking, whose main complaint upon admission to the hospital was voice hoarseness and atypical pain syndrome in the chest. During a preliminary medical examination, attention was paid to the clinical picture, atypical for a coronary heart disease – voice hoarseness was identified as a manifestation of the recurrent nerve compression, or cardio-vocal syndrome. Given the lack of connection between the chest pain and physical exertion, a high index of a smoking person as well as signs of the recurrent nerve compression syndrome, a multi-spiral computer tomography with contrasting of the chest organs was performed (in line with official recommendations of the Russian Associations of Oncologists and Otolaryngologists). The results revealed a proliferative lesion of the mediastinum and multiple focal lesions of both lungs. A subsequent thoracoscopy and biopsy confirmed the mediastinal form of a lung cancer. Promptly initiated poly-chemotherapy allowed stabilizing the patient’s condition and significantly improving his prospects. In this context, the article discusses the complexity of a timely diagnosis of a primary lung cancer and emphasizes the need to focus on specific and unique features of the disease course as well as on a broader clinical picture. Tactics of a multidisciplinary approach allows making a diagnosis in a timely manner, significantly improving the effectiveness of therapy and patient’s survival prognosis.

Two types of unusual concretions with similar biotic contents but markedly different shapes and distributions were found in close stratigraphic proximity within the Lower Jurassic Whitmore Point Member of the Moenave Formation in St. George, Utah. Both types of concretions formed in lacustrine sediments and contain abundant ganoid fish scales, numerous ostracode carapaces, and apparent rip-up clasts. Elongate, cylindrical concretions developed in parallel and regularly spaced rows in one horizon, and comparatively flat and irregularly shaped and distributed concretions formed in an overlying layer only a few centimeters above. Microprobe and Raman analyses of concretion samples reveal abundant hematite in both concretions as well as groundmass minerals dominated by silica in the cylindrical concretions and dolomite in the flat concretions. The abundance of fish skeletal debris in concretions from two consecutive horizons may suggest recurring fish mass mortality in ancient Lake Dixie, the large lake that occupied the St. George area during the Early Jurassic. We propose a model for the formation of the concretions based on their shapes, distributions, and chemistry. In this model, accumulations of disarticulated fish debris were colonized and consolidated by microbial mats and shaped by oscillatory flow (in the case of the cylindrical concretions) or lack thereof (in the case of the flat concretions). Then, after burial, groundwater chemistry and possibly the metabolic activities of microorganisms led to the precipitation of minerals around and within the masses of fish material. Finally, diagenetic alteration changed the mineral makeups of the cylindrical and flat concretions into what they are today.

Program inklusi keuangan di Asia mulai gencar dilakukan dengan fokusnya yaitu meningkatkan akses masyarakat, terutama masyarakat yang belum menikmati jasa perbankan. Hal ini menjadikan inklusi keuangan sebagai salah satu satu fokus pembangunan di sektor keuangan diberbagai negara khususnya di kawasan Asia, karena sistem keuangan yang baik dapat mendorong pertumbuhan ekonomi.Penelitian ini bertujuan untuk melihat perbandingan tingkat inklusi keuangan dan melihat pengaruh variabel sosial ekonomi terhadap inklusi keuangan di negara Asia tahun 2010-2015. Untuk melihat perbandingan tingkat inklusi keuangan di beberapa negara Asia digunakan metode analisis Index of Financial Inclusion (IFI) yang dikembangkan oleh Sarma (2008), sedangkan untuk menguji hubungan antar variabel sosial ekonomi terhadap inklusi keuangan digunakan metode Ordinary Least Square (OLS) dengan teknik estimasi dalam pendekatan Fixed Effects Model.Hasil dalam penelitian ini menunjukkan bahwa secara umum inklusi keuangan di beberapa negara Asia utamanya dipengaruhi oleh dimensi keguanaan. Selain itu, hanya variabel GDP perkapita yang tidak signifikan berpengaruh secara parsial. Sedangkan variabel lainnya, yaitu, tingkat pengangguran dan jumlah penduduk di pedesaan mempunyai pengaruh yang signifikan terhadap indeks inklusi keuangan.

Published: February 2020

Organoids are powerful biomimetic tissue models. Despite their increasing popularity, no existing methods are suitable for cell-type specific analysis of post-translational modification (PTM) signalling networks in organoids. Here we report a multivariate mass cytometry (MC) protocol for single-cell analysis of cell-type specific PTM signalling in organoid monocultures and organoids co-cultured with stromal and immune cells. Thiol-reactive Organoid Barcoding in situ (TOBis) was developed to facilitate high-throughput comparison of signalling networks between organoid cultures. Taken together, our protocol enables high-throughput multivariate PTM signalling analysis of healthy and cancerous organoids at the single-cell level.

Published: February 2020

Background: There is little population-based data on hepatocellular carcinoma (HCC) with brain metastases at initial diagnosis published. This study aimed to estimate incidence of brain metastases in initial metastatic HCC and its impact on prognosis.Methods: Newly diagnosed HCC cases from 2010 to 2015 in the Surveillance, Epidemiology, and End Results (SEER) database were screened for the presence of brain metastases. Data were stratified by age and ethnicity. Multivariable logistic and Cox regression were used to identify factors associated with brain metastases and factors associated with overall survival (OS) and cancer-specific survival (CSS), respectively. Kaplan-Meier method and log-rank test were used for survival analysis.Results: 141 cases presenting with brain metastases were identified, accounting for 0.35% of all HCC cases and 2.37% of cases with metastatic HCC disease. The incidence rate was highest among cases with age 50-59 (2.74%), respectively. Ethnicity was not associated with the presence of brain metastases at the time of HCC diagnosis. However, African American patients presented significantly lower disease-specific survival (median time: 1month; interquartile range (IQR):0-3.0 months). Initial lung or bone metastasis was independently associated with an increased risk of the presence of brain metastases (odds ratio (OR) 12.62, 95%CI 8.40-18.97), but not associated with worse OS and CSS among brain metastases cases. Conclusions: The study shows population-based incidence and survival of brain metastases at diagnosis of HCC. Brain metastases are most prevalent in initial metastatic HCC patients with lung or bone metastasis. The results may contribute to consider screening of the brain among HCC with initial lung or bone metastasis.
Estimating runtime of a job in Hadoop MapReduce

Published: February 2020

Hadoop MapReduce is a framework to process vast amounts of data in the cluster of machines in a reliable and fault-tolerant manner. To better management of this framework, estimating the runtime of a job is an important but challenging problem. In this paper, after analysis the anatomy of processing a job in Hadoop MapReduce precisely, we model each stage by relevant essential and efficient features that higher impact on runtime; then we propose two new methods to estimate the runtime, where the history of the previous run of a job is available, or a job performs for the first time. The results show less than 12% error in the estimation of runtime for the first run and less than 8.5% error when the profile or history of the job has existed.
Determinants and Stability of Money Demand during Financial Liberalization in Sub-Saharan Africa: The Case of Uganda using an ARDL Approach
Authors: Kayongo Allan , Mukisa Ibrahim , Okumu Ibrahim Mike
Published: February 2020

We analyse the determinants and stability of Uganda’s real money demand function during financial liberalization. The study contributes to literature in 4 ways, i.e.: assessing the determinants and stability of Uganda’s money demand function for the financial liberalization period; this is also done while incorporating the presumably disruptive financial innovations; assessing Uganda’s money demand stability during this episode; and applying the ARDL estimation strategy on Uganda’s Monetary Policy. GDP, exchange rate, inflation, interest rate spread and foreign interest rate explain Uganda’s real money demand. The results confirm the existence of a stable long run money demand function. The error correction term is significant and negative. Fundamentally, the financial innovations have not caused structural divergence in Uganda’s long run money demand function as would have been expected. Income is significant and close to unity and therefore a good money demand indicator in both the short and long run. Most importantly, financial innovation efforts in Uganda’s monetary policy should be intensified since they haven’t had negative effects on monetary stability.
