Published: July 2023

The paper provides the study of the topical issue of modern education which defines online learning as an environment characterized by both autonomy and limitation for all the participants of the educational process. The reasons for raising this issue have been investigated and listed as follows: necessary moving to an online due to the pandemic of recent years; technical, methodological and technological lack of preparedness of teachers to implement the educational process in a new environment; a low level of motivation of teachers and students to work online efficiently, even though having a high level of digital proficiency. The authors consider the autonomy of an online learning environment in terms of the power of digital tools to be used in solving methodological problems and designing a pedagogical scenario in the logic of achieving planned educational results. Teachers’ and students’ autonomy in an online environment is realized in: a wide choice of different ways to present educational information; a variety of technologies to increase educational motivation; the possibility of implementing the ideas of microlearning; gamification of the educational process; monitoring the psychological well-being of a students, a positive attitude; a variety of individual trajectories of learning and a significantly changed role of students; the possibility of synchronous and asynchronous work, the presenting forms of the students’ projects and its evaluation, monitoring of students’ achievements. The limitations of an online environment as the authors conclude are mostly created by the participants of the educational process. This is an automatic rejection of new requirements and conditions and resistance to changes. The teachers’ lack of preparedness to solve the educational tasks in an online environment is doubled with the poor technical conditions of the physical environment. A major role in appearing the limitations online is also played by the methodological illiteracy of the teachers and the thoughtless use of digital solutions with no reference to educational tasks. The redesign of the pedagogical scenario and role changing of all the participants of the educational process could solve the problem of limitation of an online educational environment.
ON THE ISSUE OF THE DIAGNOSIS OF FORMATION LEGAL COMPETENCE OF STUDENTS IN MEDICAL SPECIALTIES
Authors: A.D. Chestnikhina , A.M. Mityaeva
Published: July 2023

The relevance of the study is due to the contradictions arising between the needs of society for medical specialists with a high level of legal competence and insufficient work on its formation in medical universities, between the high responsibility of a doctor for violating legal norms and the still insufficient motivation of future doctors to study legal disciplines, in particular medical law as a branch of law. The purpose of the study: to develop a model for the formation of legal competence of a future doctor, which also provides a criterion-evaluation block, including criteria and methods for diagnosing the formation of legal competence.
The article discusses methods for diagnosing the formation of legal competence of students in medical specialties, its motivational, cognitive, reflexive, activity and communicative components (criteria). The survey revealed the level of formation of motivational and cognitive criteria (components) of students' legal competence, testing - cognitive criteria of legal competence, essays on the problem of medical law - the formation of reflexive and communicative criteria (components).
The results of the diagnostics of the level of formation of legal competence of students of the medical Institute confirmed their readiness to form legal competence, including in the field of medical law, including motivational, cognitive, reflexive, activity criteria, and the need for special attention to the formation of the communicative criterion of legal competence, which is least developed. By the time of studying the legal aspects of the doctor's activity, the level of formation of key indicators of legal competence does not exceed the average.
The conducted research allows us to conclude that the developed diagnostic tasks give an objective assessment of the level of formation of the legal competence of future doctors.

Published: July 2023

The article describes the main results of studying the specifics of the image of state power among the students of St. Petersburg and the Pridnestrovian Moldavian Republic, as well as their relationship with indicators of civic identity. Youth is one of the most important strategic resources of any society and at any time.
Our study examines the attitude of young people to politics, since youth is a socio-age group that largely determines the future of the state, its prospects and the socio-political stability of society.
The study was carried out in order to analyze the influence of political processes of modern society on the image of power among students.
One of the significant indicators of the image of power among students is civic identity, which is defined as an individual sense of belonging to the community of the state.
For multinational people, the lack of a civic identity is extremely dangerous, as it becomes one of the main factors of instability.

Authors: G.S. Popova
Published: July 2023

Creating environment for self-development of students is relevant in the current social and educational situation. The content of the Federal State Educational Standard has changed – it is aimed at the implementation of the activity approach, which requires more active behavior of children, schoolchildren and students themselves. Teachers and parents should enter into a subject-subject relationship with children. In 1991, the Republic of Sakha (Yakutia) adopted the Concept of renewal and development of the national school, and for the implementation of this document, the Program “Erkeei" was developed. More than thirty years have passed, a whole generation has grown up, whose children, in turn, have come to kindergartens and schools. The problem is that the new generation is leaving the linguosphere of the native language, meets difficulties in ethnocultural self-identification.The article presents approaches to the implementation of the regional model program “Erkeeii Ergiire". The used methods are: reviewing theoretical and methodological literature on the topic, logical analysis, analysis of experience based on research, methods of comparison and generalization. The results will be useful for any other region of the country where similar steps are taken to solve modern problems of cultural education.

In the modern world, which lives in a system of market relations, high technologies and a wide multimedia space, higher education has to change the concept of forms and methods of teaching students at the Higher School, including medical universities, which entailed a series of trial and error from which Of course, no one is safe. At present, Russian education is trying, however, very slowly to rebuild, overcoming the imposed direction of the globalization of higher education, the “departure” from the cliches of the Bologna Convention. The Department of Chemistry within Sechenov University, in our opinion, successfully combines traditional (fundamental) teaching methods with modern methods and forms based on the use of multimedia technologies and distance learning. Faculties "Bioengineering" and "Academic Nurse", which are quite "young" in our University, study the course of chemistry for one semester. Faculty of "Bioengineering" is mastering the physical and chemistry of natural IUDs, and students of the faculty of "Academic Nurse" are taking an integrated course in chemistry. At the end of the course, students take a test in the form of a CT (centralized testing). If we keep in mind the modern approach to the study of thought processes, then decision-making consists in choosing the right option (alternative) from a number of some options. If we turn to "decision theory", then any test is a mental action, which is a thought process. In this article, we want to analyze the creation of CT tests for the faculties of "Bioengineering and Bioinformatics" and "Academic Nurse. Teacher". Mark all "for" and "against".

Published: July 2023

In this work, an effective and low-cost method for the determination of sodium or potassiumdiclofenac is proposed in its pure form and in their pharmaceutical preparations. The method is based on thereaction between diclofenac and tetrachloro-p-benzoquinone (p-chloranil), in methanol medium. This reactionwas accelerated by irradiating of reactional mixture with microwave energy (1100 W) during 27 seconds,producing a charge transfer complex with a maximum absorption at 535 nm. The optimal reaction conditionsvalues such as reagent concentration, heating time and stability of the reaction product were determined.Beer’s law is obeyed in a concentration range from of 1.25x10 -4 to 2.00x10 -3 mol l -1 with a correlationcoefficient of 0.9993 and molar absorptivity of 0.49 x10 3 l mol -1 cm -1 . The limit of detection (LOD) was1.35x10 -5 mol l -1 and the limit of quantification (LOQ) was 4.49x10 -5 mol l -1 . In the presence of the commonexcipients, such as glucose, lactose, talc, starch, magnesium stearate, sodium sulphite, titanium dioxide,polyethyleneglycol, polyvinylpirrolidone, mannitol and benzilic alcohol no interferences were observed.The analytical results obtained by applying the proposed method compare very favorably with those givenby the United States Pharmacopeia standard procedure.

Published: July 2023

In this work is proposed a solid phase preconcentration system of Co 2+ ions and its posteriordetermination by GFAAS in which fractional factorial design and response surface methodology (RSM)were used for optimization of the variables associated with preconcentration system performance. Themethod is based on cobalt extraction as a complex Co 2+ -PAN (1:2) in a mini-column of polyurethane foam(PUF) impregnated with 1-(2-pyridylazo)-naphthol (PAN) followed by elution with HCl solution and itsdetermination by GFAAS. The chemical and flow variables studied were pH, buffer concentration, eluentconcentration and preconcentration and elution flow rates. Results obtained from fractional factorialdesign 2 5-1 showed that only the variables pH, buffer concentration and interaction (pH X bufferconcentration) based on analysis of variance (ANOVA) were statistically significant at 95% confidencelevel. Under optimised conditions, the method provided an enrichment factor of 11.6 fold with limit ofdetection and quantification of 38 and 130 ng L -1 , respectively, and linear range varying from 0.13 to 10μg L -1 . The precision (n = 9) assessed by relative standard deviation (RSD) was respectively 5.18 and2.87% for 0.3 and 3.0 μg L -1 cobalt concentrations.

Styrene is used in a variety of chemical industries. Environmental and occupational exposuresto styrene occur predominantly through inhalation. The major metabolite of styrene is present in twoenantiomeric forms, chiral R- and S- hydroxy-1-phenyl-acetic acid (R-and S-mandelic acid, MA). Thus, theconcentration of MA, particularly of its enantiomers, has been used in urine tests to determine whetherworkers have been exposed to styrene.This study describes a method of analyzing mandelic acid using molecular imprinting techniques andHPLC detection to perform the separation of diastereoisomers of mandelic acid. The molecularly imprintedpolymer (MIP) was prepared by non-covalent molecular imprinting using (+) MA, (-) MA or (+)phenylalanine, (-) phenylalanine as templates. Methacrylic acid (MAA) and ethylene glycol dimethacrylate(EGDMA) were copolymerized in the presence of the template molecules. The bulk polymerization wascarried out at 4 o C under UV radiation. The resulting MIP was grounded into 25~441⁄4m particles, whichwere slurry packed into analytical columns. After the template molecules were removed, the MIP-packedcolumns were found to be effective for the chromatographic resolution of (±)-mandelic acid. This methodis simpler and more convenient than other chromatographic methods.

The end-points obtained fromthe sharp inflections in the titration curves provide definite evidence for the formation and precipita-tion of cerium ortho-Ce 2 O 3 .V 2 O 5 , pyro-2Ce 2 O 3 .3V 2 O 5 and meta-Ce 2 O 3 .3V 2 O 5 vanadates in the neigh-borhood of pH 7.4, 6.2 and 4.8, respectively. Analytical investigations on the precipitates formed con-firm the results of the electrometric study.

One of the most important tasks in Text Mining is the formation of sufficiently large representative and consistent samples (datasets). Usually, datasets are obtained from various information sources. In some cases, due to the lack of specialized texts in Russian, the dataset is expanded by adding translated English-language documents. In such situations, it is advisable to evaluate the uniformity-heterogeneity of the combined arrays. However, such a verification is complicated by the fact that the documents are multidimensional vectors, the correct comparison of which is a very non-trivial task. Insufficient elaboration of procedures for checking the uniformity of samples for the multidimensional case leads to the fact the problem of possible differences in data is ignored that in practice as insignificant. As a result, classifiers are trained on samples that are a mixture of quite diverse texts, and the resulting quality of categorization does not improve (or even deteriorates). Thus, it seems relevant to develop a procedure for checking the uniformity of documentary samples. To do this, we provide a comprehensive study of the problem of shift in textual data, identified and analyzed the reasons that cause the heterogeneity of documentary arrays. In this study, the datasets consist of bibliographic descriptions of scientific articles (title, abstract, keywords). The authors develop a procedure for assessing the homogeneity of two samples having approximately the same volume and the same method for calculating the weights of terms. For comparison, centroids are used, which have the size of a common dictionary of two datasets (in the absence of some terms, zero values are put in the corresponding positions of the centroids). The representation of samples in the form of «terminological portraits» (centroids) allowed us to reduce the verification of the homogeneity of multidimensional document vectors to a well-studied problem of analyzing two one-dimensional connected samples, for which nonparametric criteria were used. The sign criterion and the Wilcoxon sign rank criterion were used in the study. The proposed procedure for checking the uniformity of samples was tested on three collections of documents obtained from Russian and English-language sources.

Authors: Petit Lindsay
Published: July 2023

Nurses are crucial members of the healthcare system, and they served an even larger role during the COVID-19 pandemic. Many took to the media to stay informed and followed the constant coverage of nurses’ “new normal” in the workplace. This study aimed to analyze nurses’ portrayal in the media between 2020-2022 in addition to nurses’ experiences on the COVID-19 frontline applying framing and labeling theory. A mixed method approach was employed with a content analysis of 105 coded newspaper articles and a questionnaire with open and closed ended questions in which both were thematically analyzed. Findings indicate that nurses were mostly portrayed positively by the media with support and appreciation being the most evident themes despite the mention of many negative realities the pandemic brought healthcare settings. Data from the questionnaire supports content analysis findings. This study shed light on nurses’ experiences providing direct care during COVID-19, the ways in which pandemic media coverage impacted nurses, and how coverage influenced public perception of the nursing role.

The study involved 63 patients of the pulmonology department with a history of concomitant

diseases of bronchial asthma (BA). The patients were divided into the main group 1 (27 patients who under went treatment of periodontal diseases according to the standard treatment protocol) and the main group 2 (36

patients who, in addition to standard therapy for periodontal diseases, were prescribed a course of Interleukin 1b). The control group consisted of 19 conditionally healthy people with no history of somatic pathology.

According to the criteria from the national program “Bronchial Asthma”, 27 (27 %) patients were diagnosed

with a mild form of BA, 19 (52 %) - with a moderate form, and 9 (20,1 %) – with a severe form of BA. The

selection of patients was carried out on the basis of inclusion, non-inclusion and exclusion criteria in the study.

The effectiveness of the therapy was assessed by the hygiene index (J.C. Green, J.K. Vermillion (OHI-S)), the

papillary-marginal-alveolar index (PMA) in the Parma modification. The level of destructive processes in the

bone tissue was assessed using sighting radiographs and orthopantomograms. The quality of the treatment was

assessed after 3 weeks, 4 months and then 6 months from the start of treatment.

The article is devoted to the analysis and evaluation of the main components that make up

energy drinks (ED), their effect on individual organs and systems, as well as on the body as a whole. The data

of researchers from various countries in the area of the influence of the components contained in EN on various

groups of the population are demonstrated. Considerable importance in the article is given to the combined use

of ED and alcohol, as well as the mutual enhancement of their toxic effects on the human body. It is shown

that some positive effects from the use of ED are leveled compared to the scale of their negative impact. Further

study of the negative consequences of taking ED, as well as strict regulation in the field of their advertising

and turnover, will reduce the degree of influence of this problem on humanity.

Non-Human Primates (NHP) have a slow life history compared to other mammals due to their complex brain growth. Brain complexity correlates with behaviour complexity, especially feeding behaviour, which enables primates to have the capability in leaf processing step, tool use, or even food washing. Macaca fascicularis on Tinjil Island is one of the NHP species conducting food-cleaning behaviour. Thus, this study aims to figure out the food-cleaning behaviour differences across the age classes of juvenile and male long-tailed macaques (LTM). The feeding behaviour of two age classes of male LTM through 3 different types of food processing was analysed using focal animal sampling and instantaneous recording methods. Then, the data were statistically analysed using Mann-Whitney and Kruskal-Wallis. We found that both age classes used Step 1 of the processing food type more than other types. Analysis within each age class showed different results that juvenile male LTM had a higher frequency of Step 0 and lower frequency of Step 1 than adult male LTM and vice versa. The result indicates no significant differences in the three food type processing between juvenile and adult male LTM.

Published: July 2023

Amaç: Şeker pancarı üretimi; ekonomik, sosyal, politik ve çevresel etkileri açısından tartışılan bir üründür. Üretim, üreticilerle her yıl yapılan sözleşme çerçevesinde münavebeli tarım şeklinde yapılmaktadır. Bu uygulama ile toprak verimliliği korunarak tarımsal üretimde sürdürülebilirliğe katkı sağlamak amaçlanmaktadır. Bu çalışmada, Türkiye’de şeker pancarı üretiminde önemli bir yere sahip olan Kayseri ilinin Yeşilhisar ilçesinde şeker pancarı üreticilerinin sosyo-demografik ve teknik özelliklerinin ortaya konulması ve üreticilerin münavebe yapma durumunu etkileyen faktörlerin belirlenmesi amaçlanmıştır.

Materyal ve Yöntem: Amaçlara uygun olarak çalışmada, tanımlayıcı istatistikler ve Binary Logit Modeli kullanılmıştır.

Araştırma Bulguları: Araştırma alanında üreticilerin %68.3’ünün münavebe yaptığı ve bu münavebe süresinin ortalama 2.73 yıl olduğu belirlenmiştir. Bazı değişkenlerin münavebe yapma durumuna etkisi incelendiğinde; yaş, arazi genişliği, tarımsal yayım faaliyetlerine katılım, toprak analizi yapma ve organik gübre kullanımının münavebe yapma üzerinde etkisinin olduğu saptanmış, ancak şeker pancarı üretim deneyimi ve eğitim düzeyi ile münavebe yapma durumu arasında herhangi bir ilişki tespit edilmemiştir.

Sonuç: Şeker pancarı üretiminde toprak verimliliğin korunması, hastalık ve zararlıların olumsuz etkisinin azaltılması, çevre ve toprak kirliliğinin önlenmesi, topraktaki besin maddelerinden daha iyi faydalanılması, elde edilen ürünlerin verim ve kalitesinin artırılması için münavebe uygulamalarına daha çok önem verilmelidir. Bu konuda üreticilerin farkındalığını artıracak tarımsal yayım ve eğitim çalışmaları daha çok yapılmalı ve sürdürebilir tarım teknikleri uygulamalarını teşvik edici tarım çevre politikaları tasarlanmalıdır.
