Given the rapid progress of modern science, integrative physiology holds a key place in medical education, as it studies patterns of human body functioning in terms of individual characteristics, epigenetic factors and endogenous effects on cellular mechanisms. Drawing on five years of experience in teaching physiology at Danylo Halytsky Lviv National Medical University, we highlight the importance of implementing applied integrative physiology in the training of future doctors. We present interpretation of physiological phenomena, adaptive mechanisms and compensation resources in the human body. The introduction of methods for assessing human functions in real time based on high-precision registration of individual functional characteristics and adaptive physiological mechanisms with high diagnostic value, allows future doctors to develop clinical competencies in modern principles of medical science, personalized medicine, and preventive healthcare strategies

Published: January 2022

For the prevalence of lung cancer and its poor diagnosis, the seeking of the efficient biomarkers for this disease is an urgent requirement, especially from non-invasive samples such as plasma. The mitochondria DNA (mtDNA) copy number change has been evaluated as a potential indicator of cancer risk, however, there have been few studies regarding mtDNA in plasma derived exosomes. In this study, the mtDNA copy number was measured on 29 plasma exosome samples of patients with non-small cell lung cancer (NSCLC) and 29 plasma exosome samples of cancer-free controls by real-time PCR assay, then being statistically analyzed to evaluate the relationship between these figures and several pathological features of NSCLC patients. As the results, the existence of mtDNA in exosomes isolated from plasma was detected through PCR assay using primers covering most of the mtDNA length. The relative mtDNA copy numbers determined in the exosomes of the disease and control groups were 1619.1 ± 2589.0 and 1207.0 ± 1550.0, respectively, whereas these values in two disease stages were 783.6 ± 759.3 (stage I-II) and 2647.0 ± 3584.0 (stage III-IV). Comparing among these groups, the difference was only statistically significant between the disease groups of stage I-II and stage III-IV (p<0.05), the group of stage III-IV and the control group (p<0.05). Indeed, the mtDNA copy number is associated with tumor stage and stage N (p<0.05). On the other aspect, the smoking habit of NSCLC patients could be an underlying reason behind the alteration in mtDNA copy number in the plasma exosomes. In short, our study demonstrates that the mtDNA copy number in exosomes resourced from plasma could be a potential biomarker for the detection and prognosis of NSCLC.

Authors: R REVATHY , D HEMMIGE BHARGAVI
Published: January 2022

The categorisation of gender into femininity and masculinity is purely a social construct. Advertising is a social institution which plays a significant role in the promotion of notions of gender identities at a symbolic level (Gilbert and Taylor, 1991). The purpose of this study is to understand the manifestation of masculinity and femininity in contemporary Indian print advertisements of popular Fast Moving Consumer Goods(FMCG). This study uses the theory of visual social semiotics for the analysis adopting the framework propounded by Gunther Kress and Theo Van Leeuwen (1996;2006). The representational and interactive dimensions from the framework will be used for the analysis of the advertisements. This will be further thematised to understand the nature of the representation of masculinity and femininity in them. It will also provide an insight into the relationship between the viewers and participants of these advertisements. The data for the current study includes three popular Indian magazine advertisements of FMCG products published between the years 2019-2020, selected using a purposive sampling technique.

COVID-19, one of the worst pandemics in recent years, have changed the face of our world. Every sector has been experiencing a tug in unexpected directions than anticipated. Often it is said that the healthcare sector is facing a boom in this COVID-19 episode, nevertheless there has been a decline of out-patient segment in hospitals. An out-patient is one who visits a hospital for treatment without staying overnight. Through this time of uncertainty where a new normal is being  burgeoned, the people’s attitude towards healthcare has shifted a great deal. Predominantly out-patients are hesitant to continue with their regular physician visits by delaying or avoiding unneeded visits. People with underlying diseases, both which are at low risk or at high risk, find themselves at higher caution due to the COVID-19. This study focuses to understand the attitude of out-patients and of out-patient’s with risk during this COVID-19 pandemic towards hospitals in India. Online or Tele medical consultation has picked up momentum among out-patients during the COVID-19 Unlock phase which shines a possibility as a new normal in the healthcare industry.

Published: January 2022

The paper reveales difficulties in the process of teaching the disciplines of garment production in higher educational establishment. The problem of introduction of differentiated training of future teachers of technologies at classes of design and manufacturing of textile products has been analyzed. The research substantiates the necessity of teacher`s readiness to implement a differentiated approach and suggests recommendations for its application. The conditions for successful differentiation have been determined. The development of multilevel tasks, which are an effective and most common method of differentiated learning, has been proposed. The fact that it is necessary to compare their purpose and content with the level of knowledge and skills, individual and educational capabilities of students for the development of multilevel tasks is proven. The study explores the ways to differentiate practical tasks for future teachers of labor training and technology. The peculiarities of frontal, individual and group activities of students during the classes on design, modeling and technology of textile products are revealed. The advantages and disadvantages of the above mentioned activities are identified. Considering the individual characteristics of students, it is recommended to combine them into three typological groups. The authors argue on implementation of a differentiated approach to the development of creative projects, to control the acquired knowledge of future teachers of labor training and technology, as well as the ability to apply them when solving technical problems and completing practical tasks. An experimental survey of the method of differentiated teaching of students in the process of design and manufacturing textile products has been carried out and its effectiveness has been proved.
SELF-DEVELOPMENT OF EDUCATION SEEKERS IN THE CONTEXT OF SYNERGETIC APPROACH AND POST- NEOCLASSICAL EDUCATIONAL PARADIGM
Authors: TERESHCHUK HRYHORIY , LUPAK NATALIA
Published: January 2022

The problem of self-development of a student related to the transformation of the educational process in the post- neoclassical science is highlighted. This problem is considered in the context of a synergetic approach with the actualization of the needs and opportunities for self-organization of the applicant’s personality as a holistic characteristic of a human. It is noted that the pedagogical process of an educational institution of innovative type should be aimed at developing the abilities of the applicant, their ability to meet the challenges of the information society and self-realization in the changing conditions of the modern world. It is stated that self-development of an applicant within the synergetic paradigm of education requires a reorientation of the educational process from traditional conservative to innovative creative, in which the acquisition of vital competencies is carried out in interaction (communication) with other subjects and taking into account external (physical) and internal (mental) human activity. It is substantiated that the key aspects of the self-development of the student should be focused on the formation of their optimal developmental lifestyle. It is about the ability to self-determination, personal growth, self-regulation, existence, self-expression, self-realization. In the projections of the synergetic paradigm, the individual as a complex, open, nonlinear system appears with all the potential opportunities for self-development, which can be realized under certain organizational and pedagogical conditions. It is stated that despite the fact that the applicant – the future specialist controls their own development, the teacher of higher education should exercise general management of educational activities and is fully responsible for the quality of training of the applicant. This is inherent in any level of education. The new roles of the modern teacher (“moderator”, “coach”, “tutor”, “speaker”, “medium”, etc.) set adequate requirements for these roles. Not only the updated knowledge, but also the ways of obtaining it and the possibilities of its application become valuable for the student at various stages and levels. Key aspects of self-development: the ability to self-determination, personal growth, self-regulation, existence, self-expression, self-realization will contribute to the formation of the individual’s personality, open to new knowledge and values, able to realize their own life purpose.

Published: January 2022

In the context of globalization citizenship education issues are re-emerging in the international scope, including the discussion of the citizenship education concept and the role and goal formulations of citizenship education. The problem of political education has recently become increasingly important. For example, against the background of difficult political events in Ukraine over the past two decades, it becomes clear that maintaining and developing democracy requires critical citizens of society who understand the prospects of a democratic system for the country. In order to understand current socio-political problems, it is first necessary to analyze a critical analysis of historical, political and socio-cultural developments in a society. The article was created as a part of the research project “Implications of global developments on job-related ideas of teacher training students in Austria and Ukraine” of the University College of Teacher Education Vienna, the TNPU and WUNU.

The contribution of this article to the aim of the research project is therefore to compare the citizenship education system in Ukraine and Austria and their respective historical development in order to draw the conclusions for teacher training. This contribution is closely connected with an international current discourse on central concepts of citizenship education. The article deals with the history of the citizenship education in Ukraine and Austria, shows the current state of development of this educational area and presents the results of the curriculum analysis of the pedagogical universities with regard to the implementation of political education in the context of globalization. The results of the work can help theorists and practitioners to understand the challenges of citizenship education in times of globalization.

Published: January 2022

STEM education is one of the important directions of educational reform of the XXI century. The article focuses on modern initiatives that are made in the field of STEM learning and require the development of a model of education reform that responds modern needs of society. It is noted that the proposed educational scenario confirms the hypothesis underlying this study, namely, the need to reform the existing model of educational staff training in the direction from classical education to innovative STEM education. It is substantiated that the issues of STEM education are not only issues and problems in the field of natural and mathematical sciences, engineering, advanced technologies, but also, first of all, educational policy, methodology, management and organization of activities. It is confirmed that STEM education is best implemented through a combination of its different levels: formal, non-formal, informal. The article proposes mechanisms of reforming pedagogical education for the introduction of STEM education at the Pedagogical University with aim of the training of educators of the new formation and the main components of this model. The model of pedagogical staff training includes: creation of scientific and research STEM centre, educational policy (conceptual and methodological developments of education reform model in STEM direction), increase of communication intensity on STEM education topic, promotion of STEM education ideas among the general public, increase of educators’ qualifications and practitioners involved in education. A study was conducted to test this model in practice during 2016-2020. STEM-education in Ternopil Volodymyr Hnatiuk National Pedagogical University (TNPU) was implemented taking into account the updating of the content of educational and professional programs in accordance with the requirements of the labour market, personal approach, formation of competencies and skills in the field of advanced technologies. It is established that the main indicators of the results of STEM education implementation at the university are: active participation of pupils, students, teachers in various forms of STEM training in the STEM centre of the Faculty of Physics and Mathematics of TNPU, growing interest in STEM projects and STEM practices with help of excursions, competitions, festivals, science picnics.

Published: January 2022

Objectives:

Our primary objective was to establish the efficacy of fluoride gel and fluoride varnish in the prevention of white spot lesions (WSLs) development during fixed orthodontic treatment.

Materials and Methods:

The study sample consisted of 60 adult patients in a prospective split-mouth study design. Interventions, that is, topical fluoride gel and topical fluoride varnish were assigned at the time of bonding to either the right or left halves of the dentition. In all subjects, repeated evaluation of demineralization was done on the facial surfaces of sample teeth in each quadrant. Evaluation using laser fluorescence and by direct visual observation under magnification was carried out at bonding (T0), 3 months (T1), and 6 months (T2).

Results:

The distribution of mean DIAGNOdent score at T1 (3.14 ± 1.00 vs. 2.81 ± 0.852) and T2 (4.17 ± 1.41 vs. 3.51 ± 1.13) was observed which is significantly higher in the Gel group compared to the Varnish group. In the Gel group, the distribution of mean DIAGNOdent score at T1 (3.14 ± 1.00) and T2 (4.17 ± 1.41) is significantly higher compared to mean DIAGNOdent score at baseline T0 (2.07 ± 0.66). In the Varnish group, the distribution of mean DIAGNOdent score at T1 (2.81 ± 0.852) and T2 (3.51 ± 1.13) is significantly higher compared to the mean DIAGNOdent score at T0 (2.07 ± 0.66). Visual scores also correlated with DIAGNOdent scores.

Conclusion:

Fluoride varnish is more efficacious than fluoride gel in reducing enamel demineralization. Initial application of fluoride varnish around the orthodontic bracket at bonding appointment can offer significant protection against WSLs.

Authors: Genc Esra , Buyuk S. Kutalmış
Published: January 2022

Objectives:

Maxillary impacted canines have an important place in orthodontics for the reason of being a common anomaly and its treatment is time consuming and difficult. The aim of this study was to investigate the mandibular indexes and cephalometric parameters in adolescents with impacted maxillary canines.

Materials and Methods:

The radiographs of 4026 patients aged 12–19 years old were scanned and a total of 155 patients were included in the study. Subjects were divided into three groups according to the permanent maxillary canines: Bilateral impacted canine (BIC) (52 subjects; mean age 15.02 ± 1.74 years), unilaterally impacted canine (UIC) (51 subjects; mean age 14.89 ± 1.39 years), and the control (52 subjects; mean age 14.84 ± 1.65 years) groups. Skeletal, soft tissue and dental measurements were performed on cephalometric radiographs. Mandibular index analyzes including the panoramic mandibular index (PMI), mental index (MI), antegonial index (AI), and gonial index (GI) measurements and also angular measurements of impacted maxillary canines were performed on panoramic radiographs. Data were analyzed statistically and P < 0.05 was considered significant.

Results:

Maxillary skeletal and dental measurements showed retrusive positioned maxillary dental arch in the sagittal direction in the impacted canine groups (P < 0.05). PMI and MI values were greater in the BIC and UIC groups than in control group (P < 0.05). There was no statistically significant difference in AI value among groups (P < 0.05). GI value of BIC group was found statistically lower than other groups (P < 0.05).

Conclusion:

Individuals with impacted maxillary canines have more retrusive maxillary dental arch and soft-tissue components. Furthermore, mandibular cortex was thicker in subjects with impacted maxillary canine than individuals with not and clinicians should keep in mind this when examine the panoramic radiographs in terms of early diagnosis of impacted maxillary canine teeth.

Authors: Xiong Xin , Zhang Qinlanhui , Liu Yang
Published: January 2022

Objectives:

The objective of the study is to determine the relationships between ramus height and occlusal planes (OPs) in Han Chinese individuals with normal occlusion.

Materials and Methods:

Two hundred and four participants with normal occlusion were included and their cephalograms were analyzed. The ramus height (Ar-Go), Frankfort horizontal plane-posterior OP (FH-POP), FH-anterior OP (FH-AOP) and FH-OP, anterior and posterior cranial base length, SNA, SNB, ANB, Frankfort-mandibular plane angle, SN-MP, jaw angle, and mandibular body length were measured on the subjects’ cephalograms. Pearson correlation coefficients were calculated among continuous variables. The ramus height was considered as dependent variable and the OPs as independent variables. Age, sex, and other cephalometric parameters were considered as possible confounding factors. Univariate and multivariate analyses were performed to determine whether the relationships were significant.

Results:

The FH-POP and FH-OP were moderately associated with ramus height, while the FH-AOP showed a weak association (P < 0.001). After adjusting age and sex, FH-POP, FH-AOP, and FH-OP showed significant negative associations with ramus height (β = −0.36, −0.28, and −0.37, respectively, P < 0.001). The OP flattened with the ramus height increased. After adjusting all the confounding factors, FH-POP and FH-OP showed significant negative associations with ramus height. The ramus height increased by 0.19 mm/1° flattening of FHPOP (β = −0.19, P = 0.002).

Conclusion:

After adjust age, sex, and other possible confounding factors, the FH-POP and FH-OP were associated with the ramus height. The flattening of FH-POP was associated with the increase of ramus height. The results should be treated with caution since it’s a cross-sectional study.

Published: January 2022

Objectives:

During the on-going COVID-19 pandemic, the risk to the mental well-being of the elderly living in an old age home (OAH) has increased considerably. Dealing with this issue requires special measures. The current literature has very few examples of such programmes. We aimed to promote emotional balance and an independent living with positive outlook on life among the residents of the OAH facility during the pandemic based on action learning principles. This programme was conducted in an OAH that our institute has been associated with for several years. HelpAge India, a non-governmental organisation working in India to assist disadvantaged senior citizens, provided a programme that covered 12 themes. This article deals with the structuring process of the programme.

Materials and Methods:

The team comprised homoeopathic consultants and the faculty and students of a postgraduate homoeopathic institute. An extensive literature search and consultation with experts from various fields enabled the team to plan and build the final programme were evolved.

Results:

Broad themes gave rise to distinct modules and objectives were derived for each of these. Detailed action plans were worked out and a plan of evaluation for each of these modules was worked out.

Conclusion:

Planning a programme to ensure well-being needs a close and accurate identification of the needs of the residents of a particular OAH. A multidisciplinary approach can help in evolving effective strategies to formulate models for geriatric mental well-being.

Authors: Godara Amandeep , Wang Andy Y. , Arkun Knarik , Fogaren Teresa , Qamar Adnan S. , McPhail Ellen D. , Kryzanski James , Riesenburger Ron , Comenzo Raymond
Published: January 2022

Background:

Amyloidosis is a protein misfolding disorder that leads to the deposition of beta-pleated sheets of a fibrillar derivative of various protein precursors. Identification of the type of precursor protein is integral in treatment decision-making. The presence of two different types of amyloid in the same patient is unusually rare, and there are no previous reports of two different types of amyloid deposition in the ligamentum flavum (LF) in the same patient.

Case Description:

Here, we describe two patients with spinal stenosis who underwent laminectomies and were found to have AL and ATTR amyloid deposits in the LF.

Conclusion:

As the spine is becoming recognized as a site for ATTRwt amyloid deposition, patients undergoing spinal decompression surgery may potentially benefit from evaluation for amyloidosis in the LF.

Published: January 2022

Background:

The aim of this study was to assess the safety and efficacy of chronic subdural hematoma (CSDH) evacuation by two burr-hole craniostomies under local versus general anesthesia (GA) in elderly patients over 70 years.

Methods:

This retrospective study included 45 patients with CSDH aged over 70 years old treated from March 2018 to April 2020. The cases were subdivided into Group A (n = 22) that underwent evacuation under local anesthesia and Group B (n = 23) that was treated under GA. Patients’ demographics and history of comorbidities were recorded. Variables including pre- and post-operative neurological status and Markwalder’s score, complication rate, operative time, and length of hospital stay were evaluated.

Results:

The mean and standard deviation of patients’ age of groups (A) and (B) were 74.3 ± 2.5 and 73.2 ± 1.7 years, respectively. Postoperative Glasgow Coma Scale of group (A) was statistically higher than Group B at postoperative day 1 (P = 0.01). Operative time was statistically shorter in Group A than B (P < 0.0001). The length of hospital stay was found to be longer in group (B) than (A) (P = 0.0001). The complication rate was found to be higher in group (B) than (A) (P = 0.044).

Conclusion:

Evacuation of CSDH under local anesthesia in elderly patients over 70 years is effective, safe, and economic with less complication rate than the traditional technique with GA.

This article presents the results of experimental research on thermal destruction of finishing building materials and a hazard assessment of the process. Thermal destruction of finishing materials was investigated by thermal analysis and the risk of the process was assessed by infrared spectroscopy of gaseous products resulting from thermal destruction. The thermal analysis was carried out by dynamic thermogravimetric analysis on the synchronous thermal analysis instrument NETZSCH STA 449 F3 Jupiter, which makes it possible to detect changes in mass and heat flow from temperature. The heating of the samples was carried out at a rate of 10 ℃/min in the atmosphere with a consumption of 100 ml/min. The gaseous products formed during thermal destruction were analyzed by infrared spectroscopy on IR-Fourier spectrometer «FSM 1201» with gas cell TGA 100 at wavelengths of 600-4500 cm-1. The results of the study led to the production of TG, TFG and DSK curves, describing respectively the loss of sample mass, the rate of mass loss and the change of heat flow from temperature as well as infrared spectra of products of thermal destruction of finishing building materials at various temperatures. It has been found that the finishing building materials, when thermally disrupted, form various chemical compounds, some of which are dangerous to the human body.

Проведены расчеты полей скорости и температуры, а также положение границы раздела жидкость-газ при стекании тонкой пленки жидкости по плоской подложке, наклоненной к горизонту. На подложке расположен нагреватель квадратной формы, мощность которого фиксирована, а размеры варьировались в ходе расчетов:- одним из перспективных методов отвода высоких тепловых потоков от электронного оборудования являются технологии, использующие тонкие пленки жидкости, движущиеся по охлаждаемой поверхности. Целью работы было исследование зависимости динамики и теплообмена в пленки от размера нагревателя;- на основе разработанной трехмерной нестационарной модели движения проведены расчеты теплообмена в движущейся поенке. При этом учитывалось действие всех основных физческих факторов при их взаимодействии: диффузионный и конвективный теплопереносы, зависимость вязкости от температуры, термокапиллярный эффект, появление и эволюция поверхностных деформаций;- установлено, что размер нагревателя существенно влияет на поля температуры и поверхностные деформации, а также на значение температурных экстремумов. Выведена аналитическая формула для расчета наибольшего достигаемого на подложке превышения температуры её среднего значения;- результаты могут применяться при проектировании систем охлаждения электронного оборудования.

On the basis of the developed three-dimensional non-stationary model of motion, calculations of heat transfer in a moving roll were carried out. In this case, the action of all the main physical factors during their interaction was taken into account: diffusion and convective heat transfer, the dependence of viscosity on temperature, the thermocapillary effect, the appearance and evolution of surface deformations.  it was found that the size of the heater significantly affects the temperature fields and surface deformations, as well as the value of temperature extremes. An analytical formula is derived for calculating the maximum temperature rise attainable on the substrate of its average value.

В работе рассмотрена математическая модель, описывающая движение течения стационарной, ламинарной, вязкой, несжимаемой смеси газа в трехмерном осесимметричном канале. Математическая модель, описывающая этот процесс, состоит из уравнений Навье – Стокса, уравнения неразрывности и массообмена, которые записаны в безразмерной форме с учетом осесимметричности в цилиндрической системе координат. Решение уравнений осуществляется в физических переменных «скорость – давление» на разнесенной разностной сетке. Показано влияние характерных параметров на распределение концентрации смеси газа гексафторида вольфрама и водорода в канале. Полученная математическая модель позволяет проводить численные исследования по выбору оптимальных условий осуществления процесса восстановления гексафторида вольфрама водородом.

The paper considers a mathematical model describing the flow motion of a stationary, laminar, viscous, incompressible gas mixture in a three-dimensional axisymmetric channel. The mathematical model describing this process consists of the Navier-Stokes equations, the continuity and mass transfer equations, which are written in dimensionless form taking into account axisymmetry in a cylindrical coordinate system. The equations are solved in the physical variables "velocity - pressure" on a spaced difference grid. The influence of characteristic parameters on the concentration distribution of a mixture of tungsten hexafluoride gas and hydrogen in the channel is shown. The obtained mathematical model makes it possible to conduct numerical studies on the choice of optimal conditions for the process of reduction of tungsten hexafluoride with hydrogen.

Сибунит – носитель для катализатора, использующегося в различных процессах химической промышленности, в том числе и в реакции гидрирования. В настоящее время для его подготовки и проведения технологических операций используется так называемый «сухой» способ, обладающий обширными недостатками, основными из которых являются пыление, а также значительная доля ручного труда на производстве и, как следствие, большая продолжительность отдельных стадий.Предлагается использовать «мокрый» способ с применением аппаратуры роторно-пульсационного типа для подготовки носителя катализатора с целью исключения указанных недостатков.В результате проведённой работы было установлено, что активность образцов катализаторов, полученных с использованием молотковой мельницы и с применением роторно-пульсационного аппарата в реакции гидрогенолиза составила 0,606 моль/мин и 0,642 моль/мин, при выходе целевого продукта 76,15% и 80,00%, соответственно. Также определено, что доля потерь, обусловленная образованием пыли, была снижена более чем в 10 раз по сравнению с действующей технологией.
