This study entitled The Effect of Anxiety on Students' Mathematics
Learning Achievement in SMP Negeri 28 Medan. In this study,
anxiety as an independent variable and mathematics learning
achievement as the dependent variable. Anxiety when learning
mathematics possessed by students tends to be influenced by the
image of mathematics lessons that are already known to be
frightening. This is because students recognize mathematics
subjects are difficult and complicated subjects, so that it triggers
fear of students to learn mathematics and cause anxiety when faced
with mathematics. Based on the theory, there are many factors that
influence students' mathematics learning achievement. In this
study, researchers took the anxiety factor above. This research took
place at SMP Negeri 28 Medan, which was located at Jl. Karya
Bersama No. 17 Medan Johor. The research method used in this
study is a quantitative method with a sample of all eighth grade
students totaling 273 students and divided into 8 (eight) study
groups. Data taken in the form of questionnaires and analyzed
using simple linear regression analysis. Data analysis was
performed using SPSS 21 software for Windows. From the results
of this study, it was concluded that there was no effect of anxiety
on students' mathematics learning achievement. Or in other words,
students' mathematics learning achievements are not at all affected
by the students' anxiety in facing exams, especially in mathematics.

The lecture is devoted to a new direction in clinical medicine — the possibility of using artificial intelligence — the field of computer science, which is engaged in modeling the method of acquiring and using knowledge specific to humans. The basis for a correct diagnosis is a combination of experience, the ability to think and act non-standard in difficult cases. A powerful system of generalization and classification, implemented in intelligent systems, allows you to reduce a huge number of possible situations to a small number of typical situations by which decisions or hypotheses are formed.
Extracellular vesicles (exosomes) in prokaryotic organisms: role in their biology and realization of their pathogen potential

Published: September 2020

An increasing number of gram-negative and gram-positive bacteria have been observed to secrete outer- membrane vesicles (OMVs) during their growth both under physiological and pathological conditions in vitro and in vivo. These cell-derived particles are present in many — if not all — physiological fluids. They can convey the multiple various low weight effector and signal molecules (proteins, nucleic acids, lipids, and carbohydrates) into the bacterial and host cells that have important functions in their intercellular communication and regulation. Involvement of OMVS in the various biological functions of prokariotic and eukaryotic cells make them to be key players in both physiological processes and also in pathological conditions. Additionally, the ability of OMVs to deliver molecules to recipient cell opens the possibility of their use as novel disease biomarkers and as promising drug/therapy agents. In this Review, we describe the mechanisms through which bacterial OMVs can support the host homeostasis and health and induce host pathology or immune tolerance, and discuss the possibility of these OMVs participate in innovative nanobiotechnologies.

Edge computing is a technology that allows resources to be processed or executed close to the edge of the internet. The interconnected network of devices in the Internet of Things has led to an increased amount of data, increasing internet traffic usage every year. Also, edge computing is driving applications and computing power away from the integrated points to areas close to users, leading to improved performance of the application. Despite the explosive growth of the edge computing paradigm, there are common security vulnerabilities associated with the Internet of Things applications. This paper will evaluate and analyze some of the most common security issues that pose a serious threat to the edge computing paradigm.

Published: September 2020

Pendidikan Agama Kristen adalah usaha sadar untuk menyiapkan siswa agar memahami (know), terampil melaksanakan (doing), dan mengamalkan (being) agama Kristen melalui kegiatan pendidikan. Tujuan pembelajaran pendidikan agama Kristen di sekolah ialah murid memahami, terampil melaksanakan, dan melaksanakan ajaran agama Kristen dalam kehidupan sehari-hari sehingga menjadi orang yang bertaqwa kepada Tuhan, berakhlak mulia dalam kehidupan pribadi, berkeluarga, bermasyarakat, berbangsa dan bernegara. Pengujian diperlukan agar dapat mengetahui apakah kedisiplinan mewujudkan sikap kekristenan pada keseharian siswa. Pada sekolah umum siswa beragama Kristen adalah minoritas dan hasil dari pembelajaran Pendidikan Agama Kristen cenderung kurang memuaskan, meskipun nilai yang diberikan guru adalah cukup tetapi pada dasarnya disebabkan faktor-faktor lain yang dijadikan pendukung, jika dari hasil penilaian murni, hasilnya jauh dari yang diharapkan. Oleh sebab itu dilaksanakan sebuah penelitian yang menjadi penyebab utama mengapa kedisiplinan dan motivasi siswa masih sangat rendah untuk mengikuti pelajaran Agama Kristen khususnya di SDN Manukan Kulon II dan III. Pengujian dalam penelitian ini menggunakan pengujian kuantitatif. Pengaruh kedisiplinan dalam pembelajaran Pendidikan Agama Kristen terhadap sikap keseharian siswa dalam hubunganya dengan nilai kerohanian di SDN yang diteliti oleh peneliti adalah sebesar 50,9% sedangkan 49,1% dipengaruhi oleh faktor lain, didukung oleh uji hipotesa dengan persamaan regresi Y = 10,109 + 0,915X.

Cognitive emotion regulation (i.e., reappraisal) impairment is a key feature in a wide variety of mental disorders, suggesting common nature of disruption across psychiatric diagnoses. However, the extent of potential shared neurobiological disturbances related to reappraisalimpairment is incompletely understood. This study, therefore, aimed to identify neurobiological substrates of disturbed reappraisal using a transdiagnostic approach by performing a quantitative coordinate-based meta-analysis (CBMA) on reappraisal tasks across various mental disorders. Following the best-practice guidelines for neuroimaging meta-analysis, we systematicallysearched PubMed, ScienceDirect and Web of Science databases for whole-brain neuroimaging studies published through February 2020 that compared brain activation in patients with mental disorders and matched healthy controls during a reappraisal task. Out of 1608 publications, we retrieved 32 publications with 1240 unique individuals, providing sufficient power for conducting CBMA using activation likelihood estimation (ALE) method. The reported peak coordinates for the patient/control difference in selected articles were extracted and several ALE analyses were performed to identify spatial convergence. Surprisingly, neither the pooled ALE analysis noradditional analyses restricting to in-/decreased contrasts and more homogeneous grouping of coordinates (i.e., regulation direction, stimulus valence and disorder category) provided significant convergent findings. This CBMA indicates a lack of convergent regional abnormality related to reappraisal across various mental disorders. This might be due to the complex nature of reappraisal, heterogeneous clinical populations or methodological flexibility including preprocessing and analytical methods.
Political Uncertainty Moderates Neural Evaluation of Incongruent Policy Positions
Authors: Haas Ingrid Johnsen , Baker Melissa , Gonzalez Frank
Published: September 2020

Uncertainty has been shown to impact political evaluation, yet the exact mechanisms by which uncertainty affects the minds of citizens remain unclear. This experiment examines the neural underpinnings of uncertainty in political evaluation using functional MRI (fMRI). During fMRI, participants completed an experimental task where they evaluated policy positions attributed to hypothetical political candidates. Policy positions were either congruent or incongruent with candidates’ political party affiliation and presented with varying levels of certainty. Neural activity was modeled as a function of uncertainty and incongruence. Analyses suggest that neural activity in brain regions previously implicated in affective and evaluative processing (anterior cingulate cortex, insular cortex) differed as a function of the interaction between uncertainty and incongruence, such that activation in these areas was greatest when information was both certain and incongruent and uncertainty influenced processing differently as a function of the valence of the attached information. These findings suggest that individuals are attuned to uncertainty in the stated issue positions of politicians, and that the neural processing of this uncertainty is dependent on congruence of these positions with expectations based on political party identification. Implications for the study of emotion and politics and political cognition are discussed.
The Impact of COVID-19 Probability and Cost Estimates on Worry and Health Behavior Compliance in Young Adults

Published: September 2020

The novel coronavirus COVID-19 pandemic is associated with elevated rates of anxiety and relatively lower compliance with public health guidelines in younger adults. To develop strategies for reducing anxiety and increasing adherence with health guidelines, it is important to understand the factors that contribute to anxiety and health compliance in the context of COVID-19. Earlier research has shown that greater perceived probability of negative events and their costs are associated with increased anxiety and compliance with health behaviors, but it is unclear what role they play in a novel pandemic surrounded by uncertainty. In the present study we measured 1) perceived probability as the self-reported probability of being infected and experiencing serious symptoms due to COVID-19 and 2) perceived cost as financial, real-world, physical, social and emotional consequences of being infected with COVID-19. Worry was assessed using the Penn State Worry Questionnaire (PWSQ) and health compliance was measured as endorsement of the World Health Organization (WHO) health directives for COVID-19. Our results showed that greater perceived costs of contracting the COVID-19 virus were associated with greater worry and compliance with health behaviors, even when controlling for probability estimates. Interestingly, neither self-reported worry nor its interaction with cost estimates was associated with increased engagement in health behaviors. Our results provide important insight into decision making mechanisms involved in both increased anxiety and health compliance in COVID-19 and have implications for developing psychoeducational and psychotherapeutic strategies to target both domains.
Classifying Conversational Entrainment of Speech Behavior: An Expanded Framework and Review
Authors: Wynn Camille , Borrie Stephanie A
Published: September 2020

Conversational entrainment, also known as alignment, accommodation, convergence, and coordination, is broadly defined as similarity of communicative behavior between interlocutors. Within current literature, specific terminology, definitions, and measurement approaches are wide-ranging and highly variable. As new ways of measuring and quantifying entrainment are developed and research in this area continues to expand, consistent terminology and a means of organizing entrainment research is critical, affording cohesion and assimilation of knowledge. While systems for categorizing entrainment do exist, these efforts are not entirely comprehensive in that specific measurement approaches often used within entrainment literature cannot be categorized under existing frameworks. The purpose of this review article is twofold: First, we propose an expanded version of an earlier framework which allows for the categorization of all measures of entrainment of speech behaviors and includes refinements, additions, and explanations aimed at improving its clarity and accessibility. Second, we present an extensive literature review, demonstrating how current literature fits into the given framework. We conclude with a discussion of how the proposed entrainment framework presented herein can be used to unify efforts in entrainment research.
The pictures who shall not be named: Empirical support for benefits of preview in the Visual World Paradigm
Authors: Apfelbaum Keith S , Klein-Packard Jamie , McMurray Bob
Published: September 2020

A common critique of the Visual World Paradigm (VWP) in psycholinguistic studies is that what is designed as a measure of language processes is meaningfully altered by the visual context of the task. This is crucial, particularly in studies of spoken word recognition, where the displayed images are usually seen as just a part of the measure and are not of fundamental interest. Many variants of the VWP allow participants to sample the visual scene before a trial begins. However, this could bias their interpretations of the later speech or even lead to abnormal processing strategies (e.g., comparing the input to only preactivated working memory representations). Prior work has focused only on whether preview duration changes fixation patterns. However, preview could affect a number of processes, such as visual search, that would not challenge the interpretation of the VWP. The present study uses a series of targeted manipulations of the preview period to ask if preview alters looking behavior during a trial, and why. Results show that evidence of incremental processing and phonological competition seen in the VWP are not dependent on preview, and are not enhanced by manipulations that directly encourage phonological prenaming. Moreover, some forms of preview can eliminate nuisance variance deriving from object recognition and visual search demands in order to produce a more sensitive measure of linguistic processing. These results deepen our understanding of how the visual scene interacts with language processing to drive fixations patterns in the VWP, and reinforce the value of the VWP as a tool for measuring real-time language processing.

The Ising on the Tree: The Master Model for Learning, Assessment, and Navigation
Authors: Deonovic Benjamin , Bechger Timo , Maris Gunter
Published: September 2020

Learning and assessment are intrinsically linked. However, the research, tools, and statistical models used within the two fields differ greatly. This has created a disconnect: The goals and missions of educational institutions are codified in the language and ideas of learning, but evaluated, monitored, and administered with the tools of assessment. We propose a novel statistical model, the Master model, capable of being the engine behind a modern learning and assessment system. The Master model combines three key concepts from the assessment and learning literature from the past century: A learning model should be multidimensional and hierarchical and should incorporate learning progressions. The Master model is a multidimensional latent variable model, more specifically a latent class model, that not only ranks learners from best to worst but also provides detailed diagnostic feedback to tell learners what they know, and more importantly, what they don't know. By incorporating a hierarchical structure of the latent variables, the Master model reproduces the positive manifold, a phenomenon that continues to be replicated in assessment data where scores between cognitive tests correlate positively. Finally, expert and data-driven annotation can incorporate learning progressions directly into the latent variables. With these three key concepts, the Master model can track the estimate of a learner’s latent skills, track the efficacy of various educational resources such as videos, and recommend which resources the learner should next focus on in order to maximize their learning.
A Modest Proposal for Restoration Ecology
Authors: Brick Cameron
Published: September 2020

Restoration ecology struggles to mitigate human-caused ecological damage. Non-native species are a particular challenge. This article describes two restoration attempts following introduced species in California and then makes a radical culling proposal. Environmental regulations, legal protections, and restoration projects are necessary to preserve ecosystem services, but such policies are often unpopular. Restorers often struggle when public opinion opposes evidence-based practice, and this occurs particularly when the interventions involve killing mammals. Therefore, restoration efforts may benefit from more attention to how individuals perceive the acceptability of environmental policies and how to communicate policy options effectively for individuals to make informed decisions. Restoration ecology can follow the recent shift of medicine away from imperatives and towards informed patient choice. Restoration projects may benefit from recent advances in psychology and communication that help individuals make policy decisions that align with their personal values.

Today, all developed countries are concerned about saving the lives and health of their citizens. And this is a priority task for the society. Attitude to health, awareness of its value is considered as an important element for national culture, a criterion for the well-being of society.

Regardless of age and profession, health has always taken one of the leading role in a person's life.Health is an integrated indicator of social development for any country, which reflects its political, socio-economic and moral position, a strong factor of forming demographic, economic potential of the state and society.That is why health phenomenon throughout human history has attracted the attention of many scientists from all over the world, who have developed a large number of different characteristics of this phenomenon.One of the most influential factor in the formation and maintenance of human health is education, which lays the foundation for education and culture of the entire population while studying at the university.

Students from H. S. Skovoroda Kharkiv National Pedagogical University, Primary Education Faculty took part in our experimental work. In order to understand the level of healthy development ideas for teachers and students, the importance of the teaching process and educating health, a set of research methods were used: monitoring the activities of teachers in the classroom, lesson analysis; questionnaires; group conversation, discussions, which were to solve the planned tasks.The research revealed that students do not have a high interest level in the development of health activities and readiness to implement health technologies in education. Almost half of the students do not even think about the need for a conscious attitude to health care, and therefore are not interested in these issues.

Of course, it is very important to understand that for young people the problem of health requires careful attention of all interested in it: teachers, doctors, parents, members of the public. However, a special place and responsibility in health activities is given to the educational system, which must and has all the opportunities to make the educational process health-preserving, and in this case it is not just about the health of modern students, but about the future of Ukraine.
Motivational-value attitude of students towards learning, physical education and a healthy lifestyle: comparative analysis
Authors: Muntian V. S. , Poproshaiev O. V.
Published: September 2020

The differences between the results of the study of the motivational-value attitude of students to learning, physical education and a healthy lifestyle were determined by comparative analysis of indicators with an interval of five years. The issues of increasing the level of students' motivation and their value attitude to learning (obtaining knowledge, skills, and necessary competencies) indicate the relevance of the work. Special attention should be paid to issues related to the attitude of student youth to their own health, maintaining a healthy lifestyle, getting involved in regular physical education classes, in sports and fitness sections. The study (May 2014) involved 208 students of the first (n = 102) and second (n = 106) courses (115 boys and 93 girls) of three faculties of the Yaroslav Mudryi National Law University. The survey (May 2019) involved 206 students of the first (n = 108) and second (n = 98) courses (101 boys and 105 girls) from similar faculties of the University. The conditions of the questionnaire, the representativeness of the sample, the direction and programs of training of students corresponded to the previous ones. As a result of a comparative analysis, it was revealed that the indicators with an interval of five years from the first block of questions (students' attitude to university studies) differ insignificantly, but in 2019 they are better. The second block of questions (students' attitude to physical education and a healthy lifestyle), some results differ significantly (got worse) and show a negative trend. Attitude towards a healthy lifestyle (positive): adhere to it - 8.7%, the presence of bad habits - 17.5%, alcohol consumption and smoking - 18.6%; attitude to physical culture (at school - 20.8%, at the university - 20.2%); the purpose of attending physical education classes - by 17.8%, to get credit - 17.8%, desire to go in for sports and sports and recreation activities - 14.9%. The results of the study confirmed the statement that today there is a weak or insufficient level of motivation and value attitude of students to physical education and a healthy lifestyle.
Experimental methodology for the development of speed-strength qualities of young football players 13-14 years old, taking into account the rational ratio of exercises with and without a ball
Authors: Nesterenko N.A.
Published: September 2020

The article is devoted to the problem of improving the speed-strength training of young football players of 13-14 years old, taking into account the rational ratio of exercises with and without a ball. Achieving high sports results in the process of training young football players is one of the main criteria for the success and correctness of the educational and training process. Realization of technical actions of football players during competitive activity requires a high level of speed-power qualities manifestation. Despite the presence of a significant number of studies aimed at improving the process of special physical training of football players at various stages of long-term training, the main problem is the search for modern approaches to planning the process of speed- strength training in the annual training cycle, taking into account the rational use of means, depending on the specifics of competitive activity. Hence, the most urgent problem is the development of issues of organizing speed-strength training and the selection of the most effective means, as well as their ratio. The obtained research results allow to increase the efficiency of the training process among 13-14 years old boys who specialize in football. The application of the proposed methodology allows to improve the indicators of speed-strength readiness, as the main physical quality in the chosen kind of sport.

A methodology of speed-strength training of young footballers of 13-14 years old in a one-year training cycle was developed, which was based on: the duration of the preparatory and competitive periods and their tasks; distribution of the macrocycle into mesocycles, which had their own characteristics and tasks; the content of training sessions, their orientation in mesocycles are stated.

The blocks of physical exercises and their structures developed by us formed the basis of the methodology for the development of speed-strength qualities of young football players of 13-14 years old, taking into account the rational ratio of exercises with and without a ball.

The society developments model requires a modern specialist of a wide range of knowledge, skills and competencies for successful fulfilment of their professional functions, ensuring comprehensive and sustainable development of education and science of Ukraine. A rapidly evolving modern society needs skilled workers who can compete in the labor market, are competent, responsible and free to own a profession, capable of working effectively with a specialty at world-wide standards, ready for continued professional growth, social and occupational mobility.

Postgraduate education involves the development of it through open technologies of adult‟s education, opens contingent and classes, transparency of the system, coherence of all components, as well as the conditions for free entry of subjects in the educational space, obtaining quality education without restrictions on gender, national, gender, and territorial differences. Professional self-development it is a process of forming a personality oriented to high professional achievements. In the system of postgraduate education creates the conditions for lifelong learning, accessibility in acquiring knowledge, meeting the needs and needs of the individual and society.

Advanced training uses the modern theory and practice of sports training; application of methods of functional recovery of an organism is studied; out-of-training and out-of-competition factors in training athletes, psychological training are analysed. The timing of further courses depends on the formation of the group.
Induction Chemotherapy with Docetaxel, Cisplatin and 5-Fluorouracil (TPF) Followed by Chemoradiotherapy for Locally Advanced Head and Neck Cancer: Can It Achieve Its Potential?
Authors: Rowell Nicholas P , Rowell Nicholas P
Published: September 2020

Objective: In view of concerns about toxicity and deliverability of induction chemotherapy and its impact
on subsequent chemoradiotherapy, a retrospective review was carried out with patients treated for locally
advanced head and neck cancer (LAHNC) in a single centre between 2007-2017.
Patients and Interventions: Patients with LAHNC and good performance status receiving induction
chemotherapy with docetaxel, cisplatin and 5-fluorouracil (TPF) followed by chemoradiotherapy to 70Gy
in 35 daily fractions with platinum-based chemotherapy.
Main Outcome Measures: Overall and cause-specific survival, rates of locoregional recurrence or distant
metastasis, treatment-related toxicity.
Results: One hundred and eight patients with LAHNC were treated with 1-4 cycles of TPF (95 receiving
two cycles) followed by chemoradiotherapy. The mean delivered dose intensity was 97.6% for all TPF
cycles. Median interval from the start of the final cycle of TPF to the start of radiotherapy was 24 days, with
92/103 (89%) starting radiotherapy within 28 days. Median radiation treatment time was 47 days. The mean
delivered dose intensity for chemotherapy delivered concurrently with radiotherapy was 97%. There were
significantly fewer dose reductions in those receiving platinum/5FU combinations than platinum only
regimes (P < 0.0001). For those receiving two cycles of TPF, 90% of patients completed the whole course
of treatment within 14 weeks (median overall treatment time 13.1 weeks). There were four treatment-related
deaths during induction chemotherapy and none during radiotherapy. Twenty-five developed locoregional
failure and 13 distant metastases (both in eight). Actuarial overall survival was 60.7% at five years, with
progression-free survival of 77.9% at two years and 74.1% at five years. For oropharynx cancers, overall
survival was 70.4% and progression-free survival 80.8% at five years.
Conclusion: Although significant toxicity from TPF was observed, with appropriate support, it is possible
to complete treatment without undue compromise of subsequent treatment.

The study adopted the descriptive survey research design. Two hundred (200) undergraduates were randomly selected from four (4) randomly selected universities in Osun state. A structured questionnaire entitled Factors Affecting Students’ Academic Performance Questionnaire (FASAPQ) which had four sections was developed and validated. Frequency counts, simple and percentage and Analysis of Variance (ANOVA) were used to analyse the data collected. The findings of the study show that age had influence on students’ academic performance in tertiary institutions. The findings also revealed that the peer group had influence on students’ academic performance in tertiary institutions. The results also supported the idea that learning environment had influence on students’ academic performance in tertiary institutions. Furthermore, the difference in the students’ across institutions perception on factors affecting the academic performance of students in tertiary institutions was found insignificant (F(3,196) = 1.138, p>0.05).Based on the findings of the study, the following recommendations were made: the school counsellors should be organizing orientation programmes for new undergraduates to get them familiar with the new environment and to understand the university.

Objective: To assess the effectiveness of an eight-week nutrition and physical activity intervention, entitled: “My Healthy Habits”, at summer camps to prevent obesity, reduce screen time, promote healthy eating habits and physical activity among children. Material and Methods: Eight-week pretest-posttest: intervention versus a comparison group was conducted, in two comparable summer camps in Kuwait and randomized at the site level. Convenient sampling (n=79) included children aged 6-10, receiving 8 weeks of nutrition education: 2 days/week, 40 minutes/day and physical activity sessions: 4 days/week for 20 minutes/day. Outcomes included: the Modified Healthy Habits Survey (items about diet, physical activity and sedentary behavior) and anthropomorphic: Body mass index (BMI) for age and gender percentile and waist-to-height ratio (WHtR). Group changes were measured by independent t-test, and within group changes by the McNemar’s test (categorical data) and paired t-test (interval data). Results: Significant increases in nutrition knowledge scores (from 4.3±1.7 to 10.5±1.2) and in the total score of the major food groups (from 10.0±2.6 to 13.7±2.2) were observed from pretest to posttest. Healthy eating significantly increased (from 12.8±1.8 to 14.5±1.5) for the intervention group only; however, intake of French fries, chips (FF) and sugarsweetened beverages (SSB) remained the same for both groups. Physical activity increased and screen time decreased,only in the intervention group. The participants’ BMI and WHtR decreased significantly in the intervention group: p-value=0.001. Conclusion: Healthy food and physical activity increased, while screen time decreased. Consumption of unhealthy food (FF and SSB) remains an issue.
Secondary metabolites of tea leaves and their role in protecting against environmental stressors

The dynamics of a number of secondary metabolites and the activity of guaiacol peroxidase in 3-leaf sprout of tea varieties and forms were studied. In the course of 3-year research we noted the presence of declines and peaks in the activity of the enzyme and the accumulation of flavonoids, carotenoids, caffeine and amino acids associated with the meteorological conditions of each month. It is shown that there is a close inverse relationship between increased enzyme activity, carotenoid content and hydrothermal factors. The most significant correlation was found between the activity of guaiacol peroxidase and carotenoids in a 3-leaf tea flush with precipitation (r = -0.86 and -0.68). At the beginning of vegetation the enzyme activity is low (ranging from 0.363 to 0.607 units/g·s). The decrease in the activity of guaiacol peroxidase in June is due to the biological peculiarities of the tea culture associated with a period of rest, during which the metabolic processes are somewhat slowed down. Increased activity of guaiacol peroxidase is accompanied by rapid synthesis of phenolic compounds, such as flavonoids. We have traced the dynamics of the formation of thearubigins and theaflavins in tea sprout. It is shown that their amount varies depending on the season of collection from 0.075 mg/g (theaflavins) and 1.178 mg/g (thearubigins) to 0.115 mg/g and 1.625 mg/g (theaflavins and thearubigins, respectively) and their dynamics is similar. The content of the routine varies depending on the season of tea leaf collection. The synthesis of caffeine also depends on the growing conditions, the active accumulation of which in experimental plants was observed in July (on average 26.6±1.4 mg/g). The largest amount of amino acids (16 665 mg/g) is synthesized in May, and then their synthesis is halved. Genotypic peculiarities are manifested in the content of secondary metabolites and the activity of guaiacol peroxidase. The revealed patterns are common for all varieties and forms of tea.
