A websérie “Se eu estivesse aí” chama atenção pela promessa de ser “imersiva em 1ª pessoa e áudio 3D”. Ainda há o uso do Instagram, o que não é usual neste tipo de produção. O contexto da pandemia de Covid-19, tema e também reflexo da construção da própria obra, encaminha a maneira como experimentamos a websérie. Gustavo Vaz e Débora Falabella são os únicos atores em cena, protagonistas de uma relação que está profundamente abalada pelas restrições impostas pela pandemia. O som é o destaque da produção, com a história sendo contada por meio de mensagens de áudio. A análise feita por este e-book busca refletir sobre esta obra e sobre um tipo de produto feito de forma bastante caseira, por conta dos limites impostos pelo isolamento social. A inovação buscada é o tema central do estudo, que reflete sobre imersão, narrativas e a sensação de isolamento.

THE CONCEPT AND STUDY OF CULTURE
Authors:   Mariupol State University, Jankowski S.
Published: September 2023

The article introduces an analogy of epistemology of culture. It demonstrates the specific political economy of the scientific fields of Ukrainian humanities. The factors that determine it should be sought in the realm of the competition of actors in the scientific field for primacy in the redistribution of cultural capital, the peculiarities of the formation of the expert field in the cultural sphere, as well as the mythology of “human universal values” inherited from the post-Soviet era. Its discourse is a means of reproducing the intellectual imperialism of Moscow-Russian culture. The implemented conventional understanding of culture is the key to distinguish cultural studies into an independent field in scientific knowledge. It is indisputable that Ukrainian humanities have made significant steps towards establishing cultural studies as an independent academic discipline. We must acknowledge the significant contribution of domestic scientists to defining the mission of university cultural education in Ukraine. The general purpose of this investigation is to highlight the conventional understanding of the concept and studies of culture. According to this approach, culture appears as an infrastructural unity of three universes: the universe of beliefs, the universe of application, and the symbolic universe. It opens the perspective of the emancipation of the study of culture or cultural studies into a scientific field, which should free itself from the residual influence of the post-Soviet intellectual tradition, the discourses of “universal humanity” brought from it. Conventional understanding of culture helps to liberate its understanding from the chains of its political, historical, geographical engagement, avoids its dispersion in various discourses of the scientific field of humanitarian and social knowledge, teaches to perceive and investigate culture in a different way than historians, experts in the political field, philologists and linguists, etc. do. Keywords: analogy of epistemology of culture, ambiguity of epistemological situation, political economy of scientific fields, epistemology of culture, conventional understanding of culture, engagement of cultural studies.
THE DEVELOPMENT OF THE UKRAINIAN VARIETY ART: FROM IMITATION TO THE ESTABLISHMENT OF NATIONAL CONTENT
Authors:   Kyiv National University of Culture and Arts, Burlaka A.
Published: September 2023

The Ukrainian variety art is a phenomenon that reflects changes in cultural and value orientations of society. In the Soviet Union popular music developed under the strict control of censorship, which conditioned the development of only a certain vector of musical art. This hampered the process of assimilation of a new cultural and artistic product emerging in the West. Censorship in itself is not an exclusively negative phenomenon, because it can prevent the formation of extremism, chauvinism, racism in society. However, the example of the Soviet censorship proved that it inhibited social development and acted as a factor contributing to the preservation of outdated elements of cultural life. All the achievements of foreign pop music were banned. After Ukraine gained its independence, it began to adopt the themes, styles, and genres that were characteristic of the American pop scene. The analysis of the songs reveals a preference for love themes, which dominate most of the lyrical songs. The theme of love is central to songs that have topped various charts over the past 50 years. Taking into account that pop music is created to achieve commercial success, the portrayal of love and unrequited love is extremely appealing to any audience. The writers of America's top-charting pop songs were masters of using poetry as a tool to get across their point, employing a rich system of similes: love like oxygen, like a butterfly, like heat, like a bridge over troubled water, sweet like honey. Love was also mentioned in a metaphorical sense: battlefield, devil, drug, temple, higher law. Listeners are much more receptive to metaphorical language because metaphor helps us effectively express complex concepts and emotions. With the spread of globalization, cultural identity has gained relevance. In Ukrainian music, the desire for national and cultural identity manifested itself in the development of folklore, more precisely in the inclusion of its elements in pop music. As a result, two opposing processes are taking place in the Ukrainian pop music - the desire to create a standardized (Americanized) musical product and a unique ethnic one. This latter type of musical production is associated with the formation of a national product, which may contain folklore motifs, instruments, etc. A stable factor is the development of love themes and the use of styles that originated in foreign space. On the other hand, among the latest trends, that can be attributed to new tendencies is the spread of patriotic themes in Ukrainian pop music and the formation of nationally colored content. Key words: Ukrainian pop music, song, theme, national, identity, product, globalization.
CULTURAL AND PEDAGOGICAL ASPECTS OF STAGE FRIGHT IN THE PRACTICE OF PIANIST PERFORMER
Authors:   Ukrainian National Tchaikovsky Academy of Music, Makarova N.
Published: September 2023

The article presents a theoretical overview of the topic of stage fright; the author gives the definition of stage excitement by various theorists and researchers such as H.M. Kohan, K.S. Stanislavskyi, E. Ekonomova, A. Sannikova, F. Vasyliuk and others. The paper describes in detail the theory of stage fright by the famous American social psychologist D. Kenny. Stage activity is always accompanied by excitement, but some performers know how to use the situation to accumulate and activate their creative potential, while others get frightened and do not even have the opportunity to bring half of the material they have learnt at home to the stage. The memory fails, a terrible hand tremor occurs that cannot be controlled, the concert no longer looks like a joyful performance, and the performer has a desire to leave the stage as soon as possible. If this situation is repeated often, then after a while the musician will either have to give up performing or change his or her profession. Key words: stage, fright, stage fright, variety fright, performance, pianist-performer, anxiety.

Competitiveness of Ukrainian metal in the world market is stipulated by high technical re-quirements for its quality in general, including its mechanical properties. Introduction of effec-tive systems of automated control of the mechanical properties of heavy-plate mills will signif-icantly improve their quality. The article describes the formulation of the problem of control-ling mechanical properties of heavy-plate rolled products, and mathematical models for fore-casting their mechanical properties. The main technical solutions are implemented into the au-tomated control system of mechanical properties of rolled products. The developed system of automated control of their mechanical properties is included into the APCS of heavy-plate mills rolling, as well as the software and hardware for this complex system is partially common to both components. APCS of the rolling process is functionally combined with the control system of the mechanical properties of rolled products. Five programmable controllers built on a PC, as well as monitors, a corresponding keyboard and printers are used to control these properties. For the organization of the automated system of control and management of mechanical proper-ties there is used a �manual� organizational and technical structure. To test the developed sys-tem and its algorithms, there was created a laboratory installation which allowed to perform simulation of the automated control system of the mechanical properties of rolled products on the basis of a PC. During the simulation there was used experimental data from a real techno-logical object and confirmed the operability of the obtained scientific and technical solutions. Stated above solutions to control the mechanical properties of rolled products can be used in the development of the APCS of heavy-plate mills.
The new method of forestation automation with uav and through-the-air seedling delivery tech-nique based on the lidar generated land surface model optimization.

Published: September 2023

Deforestation is one of the biggest ecological challenges faced globally nowadays. From 1993 to 2020 the world lost almost 154 Mha of forests which brought about various negative conse-quences, such as an increase in greenhouse gas emissions, disruption of water cycles, increased soil erosion, disrupted livelihoods, etc. Scientists agree that artificial forestation is the only way to solve the problem on its present scale. Classic methods of artificial forestation include man-ual and automated ones or their combination. Despite its simplicity and comparably easier im-provement, classic methods also have some disadvantages that do not allow them to solve the problem, i.e., bad scalability. Automated forestation that utilizes UAVs is a new promising ap-proach that was developed in the last decades. The current paper addresses its common imple-mentations compared to classic forestation methods from the perspective of its improvement possibility based on their synthesis. Analysis of the existing experience of UAV-based foresta-tion consists of three stages: surface scanning, data processing and planting itself. The research showed that in addition to the usage of modelling and optimization algorithms at the first two stages, analogically to classic methods higher efficiency can be achieved by planting seedlings instead of seeds. The present paper suggests performing planting from the air to the defined points based on the creation and optimization of a tree situation model. Such approach requires the usage of advanced LIDAR generated land surface modelling techniques and methods of tra-jectory calculation. The article describes a step-by-step new method of tree planting automa-tion, suggesting theoretical and practical perspectives and directions for future research.
Features of the process of object classification on the basis of discriminant functions

An alternative approach to the processing of elements of linear discriminant functions for the classification of objects is proposed in the paper. This approach is based on the method of processing a vector array of data by differential slices which is distributed in the column of matrix representation of elements of discriminant functions. In its turn, it indicates the spatially distributed nature of the processing of matrix elements with dimension m ? n, where m is the number of classes, n is the dimension of the input data vector. The linearity of the representation of each discriminant function in a set of discriminant functions allows not only to represent their terms in the form of matrix elements, but also apply to their processing some rules concerning such properties as associativity and commutativity of components (terms) of the sum. As a result, such complex procedures as multi-operand summation in the formation of each discriminant function are replaced. Moreover, it is followed by their comparison with each other with the aim of identifying the one with the maximum value. In each processing cycle of the proposed method, the basic operation is a simultaneous reduction in the magnitude of the elements similarity of the same name in the columns of the matrix, which allows determining the maximum value of the discriminant function. The operation of transposition (advancement) to the edge of all current zero elements in each row of the matrix is also involved. This approach is applied to linear discriminant functions as an apparatus of the statistical method of object classification. Consequently, according to the known decision rule, the maximum discriminant function determines the corresponding class to which the input object, represented as an n-dimensional feature vector, belongs. One of the options for the hardware application of such classifier is the decision support subsystem for medical diagnosis.
Micro-Celebrities or Teacher Leaders? An Analysis of Spanish Educators’ Behaviors on Twitter
Authors: Marcelo Carlos , Murillo Paulino , Marcelo-Martínez Paula , Yot-Domínguez Carmen , Yanes-Cabrera Cristina
Published: September 2023

Social networking sites have become affinity spaces for teachers. Many teachers use them with different intentions and motivations, including learning. On social media platforms there are active teachers who have developed a certain leadership and recognition from many teachers. In some areas, like marketing or fashion, people with influence are called influencers. This paper investigates who they are, how their network is configured and how they perceive themselves. The questions that directed our research were: Who are the predominant Spanish teacher leaders on Twitter? What is the network structure that characterizes them? What perceptions do these teacher leaders have about their role and its impact on their professional development as teachers and others? This study has two distinct but interrelated phases. We investigated the structure and relationships among 54 Spanish teacher leaders. Using a social network analysis (SNA) approach, through the analysis of the social behavior of these teachers on the social network Twitter, we first identify educational profiles who have a high degree of centrality in the network. These are teachers who are recognized as opinion leaders by a significant proportion of their fellows. In addition to the degree of centrality that tells us how relevant a user is in a specific digital community, we identified teachers who play a key role in the circulation of information in the network studied. In some way, these teachers share common characteristics with activists in other fields. Of the 54 teachers, we selected 20 who were then interviewed. The findings demonstrate that they don't consider themselves micro-celebrities or influencers. We found a lack of identification not only with the term, but also with the image of an influencer which was understood as banal, superficial, commercial, and far from what they do in social networks.These teachers develop their identity as new digital artisans who foster a culture of collaboration and create affinity spaces that allow informal learning. Their motivation is intrinsic, through recognition and prestige among other teachers, which leads them to build a kind of constructivist leadership.
Метод сумарних представлень розв’язання задач про математичний сейф на матрицях у скінченних полях

Published: September 2023

Розглядається один з існуючих методів розв’язання задачі про математичний сейф — метод сумарних представлень, розроблений для графів та матриць, теоретично описаний і обгрунтований у попередніх роботах. Ідея методу полягає у пошуку спеціального параметра S який називається сумою невідомих, що представляють розв’язок вихідної системи рівнянь. В існуючому методі сумарних представлень на матрицях це досягається шляхом розв’язання спеціальної додаткової системи рівнянь, яка є зваженою сумою рівнянь вихідної системи з коефіцієнтами di, i=1,2,…,n а сама сума рівна dS де d — невідома константа. Дослідженнями обгрунтовано метод як інструмент розв’язку задач про математичний сейф, але метод чутливий до виняткових випадків, коли розв’язку не існує (значення параметра d кратне, де K — кількість станів кожного замка в сейфі), і потребує корекції початкових станів сейфу. Тому в даній статті пропонується метод сумарних представлень на матрицях, який дозволить отримати універсальний та стійкий метод розв’язку задач про математичний сейф довільного обсягу. Особливістю методу є «сегментація» висхідної системи рівнянь відносно змінних xij та введення оператора σi=∑xij який, на відміну від методу сумарних представлень розв’язання задачі про математичний сейф на графах, є частковою сумою при фіксованому номері j Завдяки введенню додаткового оператора σj отримаємо можливість розв’язку висхідної системи: xij=si+σj+bij Метод продемонстровано на прикладі, який підтвердив його ефективність та якість. Проведено аналіз арифметичної складності алгоритму методу сумарних представлень у порівнянні з класичним методом Гаусса.

Системи на основі сучасних інтелектуальних технологій сенсорного та супутникового моніторингу здатні відстежувати та контролювати віддалені території навколишнього середовища в реальному часі та сприяють швидкому реагуванню на його зміни, перш ніж це стане проблемою. Вони дозволяють ефективніше використовувати наявні ресурси, оскільки дані можна відстежувати та контролювати віддалено, без необхідності фізичного доступу. Сучасні супутникові датчики дозволяють отримати зображення об’єктів земної поверхні з високою роздільною здатністю, що дозволяє створювати детальні карти навколишнього середовища Землі та робить космічний моніторинг потужним та ефективним інструментом як аналізу кліматичних змін, екологічних катастроф та глобального впливу людської діяльності на стан екосистем, так і їхнього попередження. В даній роботі досліджуються та визначаються найбільш інформативні спектральні канали супутника Sentinel-2 з метою їхнього подальшого аналізу в процесі супутникового моніторингу пошкоджених лісів. Сформовано дослідницький набір даних безхмарних супутникових знімків (тестового датасету (набору даних) по території Франції) у вигляді часового ряду супутникових знімків для дистанційного моніторингу лісових ділянок (до та після пошкодження). Отриманий набір безхмарних супутникових знімків складається з 5573 зображень. На прикладі вегетаційного індексу NDVI перевірена гіпотеза щодо зменшення його середнього значення та зростання його стандартного відхилення при появі на певній ділянці хвойного лісу пошкодження (захворювання чи засихання). Отримані результати можуть використовуватися при машинному навчанні алгоритмів класифікації пошкоджених лісів. Дослідження проводилось відповідно до наукових цілей європейського проєкту «Satellites for Wilderness Inspection and Forest Threat Tracking» (SWIFTT).
Mechanical Performance of Salvadora Persical (Miswak) Reinforced Polylactic Acid Matrix Composites for Three Dimensional Printing
Authors: KARTAL Fuat , KAPTAN Arslan
Published: September 2023

This study examines the mechanical performance of polylactic acid (PLA) matrix composites reinforced with Salvadora Persica (Miswak). With the increasing use of environmentally friendly materials, researchers are focusing on the production of biodegradable materials. However, incompatibility between PLA and filler materials used in PLA composites causes mechanical problems during production. This study deals with the production and characterization of PLA composites containing lignocellulosic and inorganic fillers using maleic anhydride grafted polylactic acid (PLA/g/MA) as a matrix. The aim of the research is to examine the mechanical specifications of Miswak powder reinforced PLA composites and to evaluate their suitability for practical applications. PLA was used as the matrix material and PLA/g/MA was used as the compatibilizer. Composites containing Miswak powder at different weight concentrations (5%, 10%, 15% and 20%) were characterized using scanning electron microscopy along with tensile and bending tests. The obtained results showed that different Miswak concentrations affect the mechanical specifications of the composites. Composites at 5% concentration demonstrated excellent interlayer adhesion and high mechanical strength, demonstrating favorable mechanical specifications. The findings show that Miswak powder is a potential filling material to improve the mechanical specifications of PLA composites and provide antimicrobial benefits. The results of this study shed light on the mechanical performance of Miswak reinforced PLA matrix composites, which are promising for 3D printing applications. In addition, it is stated that the materials used, such as natural filling materials, contribute to the development of sustainable and environmentally friendly materials by reducing the environmental impact.

Published: September 2023

This article presents the analysis of Strut-and-Tie Model (STM) in reinforced concrete 3D structures based on the study of topological optimization, so that the problem is formulated with the Smooth-ESO (SESO) discrete method, whose removal heuristic is bidirectional with discrete optimization procedure, and the Velocity Field Level Set Method (VFLSM), which is an inheritance of the classical continuum Level Set Method (LSM), but advances the design limits with a velocity field constructed from the rate of the design variables and base functions. The proposed approach is to couple both methods in conjunction with the Method of Moving Asymptotes (MMA), used to control the various design constraints that are the minimization of compliance and the Von Mises stress that has demonstrated more rational STM results. Additionally, it has been formulated a methodology for the automatic generation of optimal of 3D STM by using sensitivity analysis obtaining via derivatives of the Von Mises stress fields, finding the force paths prevailing compression in the directions of the strut and the tensile in the directions of the ties for the reinforcement insertion. All the codes are implemented with Matlab software and several comparison examples: Deep beam with opening, a pile cap, a bridge pier, and a single corbel, are presented to validate the present formulations and the results are compared with the literature

Цель исследования — изучение связи сывороточного уровня VEGF с концентрацией С-РБ, фибриногена, цистатина С и количеством тромбоцитов, а также показателями расчетной СКФ у лиц пожилого и старческого возраста. В исследование были включены 124 человека 60–89 лет (40 мужчин и 84 женщин), средний возраст составил 68,8±7,4 года. В работе изучены сывороточный уровень VEGF, параметры липидного спектра крови, концентрация С-РБ, фибриногена и величины СКФ по формуле CKD-EPI и по методике F. Hoek. У 15,3 % обследованных лиц пожилого и старческого возраста отмечали увеличение уровня VEGF, который положительно коррелировал с содержанием С-РБ (r=0,411), числом тромбоцитов (r=0,358) и с концентрацией цистатина С (r=0,211). В подгруппе пациентов с повышенным уровнем VEGF количество тромбоцитов, концентрация С-РБ, фибриногена, цистатина С были значимо выше, а величина расчетной СКФ по F. Hoek оказалась достоверно ниже. Повышенный сывороточный уровень VEGF за счет его потенциального провоспалительного и протромбогенного эффекта у лиц пожилого и старческого возраста, особенно при наличии снижения СКФ, следует рассматривать как плохой прогностический фактор течения атеротромботических сердечно-сосудистых событий.

The aim of the study was to study the role of serum vascular endothelial growth factor and to determine its clinical signifi cance in elderly and senile patients. The study included 124 people (40 men and 84 women) aged 60 to 89 years, the average age was 68,8±7,4 years. Serum levels of vascular endothelial growth factor (VEGF) were studied in the work; blood lipid spectrum parameters, indicators of acute phase blood proteins: C-reactive protein (C-RP), fi brinogen; glomerular fi ltration rate (GFR) according to the CKD–EPI formula based on serum creatinine and according to the F. Hoek method using cystatin C. In general, 15,3% of the examined individuals had elevated serum levels of VEGF, more often in elderly patients. It was found that serum levels of VEGF are positively associated with the concentration of CRP (r=0,411), the number of platelets in peripheral blood (r=0,358) and positive with the concentration of serum cystatin C (r=0,211). In the subgroup of patients with an elevated serum VEGF level, the platelet count, the concentration of C-RP, fi brinogen, and cystatin C were signifi cantly higher, and the calculated GFR according to F. Hoek was signifi cantly lower. Patients with an elevated serum VEGF level, as a pro-infl ammatory and prothrombogenic potential, especially if it is associated with the development of kidney dysfunction in the elderly and senile, should be considered as a risk group for atherothrombotic cardiovascular events.

Поиск литературных источников в отечественных и зарубежных базах данных продемонстрировал отсутствие работ, посвященных изучению факторов риска венозных тромбоэмболических осложнений (ВТЭО) у пациентов старшей возрастной группы с сахарным диабетом, планируемых к оперативным вмешательствам на позвоночнике, что и явилось побудительным моментом к проведению исследования. Цель — изучение факторов риска ВТЭО у пациентов пожилого и старческого возраста с сахарным диабетом, планируемых к оперативным вмешательствам на позвоночнике. В одноцентровое ретроспективное исследование были включены 119 пациентов (64 мужчины, 55 женщин, средний возраст — 74,2±6,5 лет) пожилого и старческого возраста, которым выполнены различные оперативные вмешательства на позвоночном столбе. Согласно модели бинарной логистической регрессии, статистически значимо ассоциированы с развитием ВТЭО у изучаемой группы респондентов следующие параметры: возраст пациентов свыше 75 лет (р=0,048), уровень HbA1c >7,5 % (р=0,007) и D-димера >0,5 мг/л FEU (р=0,034), а также высокая степень риска (5 баллов и более) ВТЭО по шкале Caprini (р=0,012). Для снижения частоты встречаемости ВТЭО у пациентов пожилого и старческого возраста с сахарным диабетом, которым планируются оперативные вмешательства на позвоночнике, необходимо верифицировать перечисленные выше клинико-лабораторные параметры на ранних этапах госпитализации.

The search for literature sources in domestic and foreign databases showed the absence of works devoted to the study of risk factors for venous thromboembolic events (VTE) in patients of the older age group with diabetes mellitus who are planned to undergo surgical interventions on the spine, which was the impetus for this study. The aim of the study was to study the risk factors for VTE in elderly and senile patients with diabetes mellitus who are scheduled for spinal surgery. A single-center retrospective study included 119 elderly and senile patients (64 men, 55 women, mean age 74,2±6,5 years) who underwent various surgical interventions on the spinal column. According to the binary logistic regression model, the following parameters are statistically signifi cantly associated with the development of VTEC in the studied group of respondents: age of patients over 75 years (p=0,048), HbA1c levels over 7,5% (p=0,007) and D-dimer over 0,5 mg/l FEU (p=0,034), as well as high risk (5 points or more) of VTE according to Caprini scale (p=0,012). In order to reduce the incidence of VTE in elderly and senile patients with diabetes mellitus who are planned to perform surgical interventions on the spine, it is necessary to verify the above clinical and laboratory parameters in the early stages of hospitalization.

Старение приводит к глубоким изменениям в гомеостазе углеводного обмена, который считается хорошим предиктором здоровья и увеличения продолжительности жизни. Цель работы — изучение основных характеристик углеводного обмена у мужчин-северян пожилого возраста, проживающих в условиях Северо-Восточного региона России (Магадан). Результаты исследования показали, что нарушение углеводного обмена у здоровых мужчин пожилого возраста проявлялось высоким уровнем глюкозы в плазме натощак (5,81±0,20 ммоль/л), гликированного гемоглобина (5,73±0,12 %) главным образом из-за повышенной резистентности к инсулину (HOMA-IR составил 2,63±0,25 у. е.), а не снижения функции β-клеток поджелудочной железы (HOMA-β составил 96,85±6,10 %), при отсутствии компенсаторного возрастания уровня базального инсулина (9,97±0,81 мкМе/мл). Выявленное нарушение углеводного обмена у здоровых мужчин пожилого возраста отражает тенденцию снижения кардиометаболического здоровья у пожилых жителей-северян. Данные, полученные в нашей работе, согласуются с представленными в литературе результатами исследований других авторов и свидетельствуют о формировании возраст-ассоциированной патологии, приводящей к ускоренному старению организма.

Aging normally leads to profound changes in the homeostasis of carbohydrate metabolism, which is considered a good predictor of health state and life expectancy. The objective of this study was assessing main indicators of carbohydrate metabolism in Northern men of older ages living under conditions of the North-Eastern region of Russia (Magadan). The results of the study showed carbohydrate disorders in healthy elderly men who exhibited high values of fasting plasma glucose (5,81±0,20 mmol/L) and glycosylated hemoglobin (5,73±0,12%), mainly owing to elevated insulin resistance (HOMA-IR was 2,63±0,25 arb. units), and not to reduced pancreatic β-cells function (HOMA-β was 96,85±6,10%), in the absence of a compensatory increase in basal insulin levels (9,97±0,81 μm/mL). Carbohydrate metabolism tenduence in healthy elderly men appears to worsen cardiometabolic health in older residents of the North. Our data confi rm those by other authors and indicate the formation of ageassociated pathology that causes accelerated aging of the body.

Those working in the ground handling of aircraft at the airport in the process of performing their activities are exposed to the impact of a complex of harmful and dangerous risk factors, including noise. Noise in the working environment above 85 dB(A) is one of the first unfavorable factors at the airport that affect the functional state of various organs and systems in the human body. Exposure to noise in the work environment at or above 85 dB(A) can cause a number of complaints related to the central and autonomic nervous systems, disorders in the vestibular and auditory apparatus up to permanent hearing loss, reduced work capacity, impaired concentration, fatigue, difficulty in verbal communication, the ability to hear warning signals, respond to environmental sounds, etc. All this affects the general safety and is a prerequisite for the occurrence of aviation accidents caused by the human factor. The purpose of the present study is to present the results of research conducted on noise at the airport itself and its impact on ground staff, by deriving good practices and examples, to make general conclusions and proposals with a practical orientation for the introduction of a standard for health monitoring and prevention of the risk of noise exposure among airport ground handling workers. The methods used are documentary, formal-logical with analysis of official documents, systematic review of articles and data in the surveyed area. The results of the survey show the lack of clear legal rules and standards in the Republic of Bulgaria regarding the health screening of hearing for those working in environments with excessive noise levels, including for ground handling operators at airports. Therefore, solutions to this problem must be implemented, in particular through the introduction of a standard and the introduction of clear criteria for health monitoring, engineering, ergonomic knowledge and preventive measures. Hearing prevention, early screening and health monitoring among workers at excessive levels of noise in the work environment should be a priority of every legislation, responsibility and obligation of every employer.

For the purposes of the research, 358 patients treated by fourth, fifth- and sixth year students in the facility of the Faculty of Dental Medicine at the Medical University of Varna - were surveyed. Results: There is a positive correlation observed from the survey between effective doctor-patient communication and patient satisfaction with the quality of dental services provided. Good communication with the patient strengthens the trust in the dentist and helps the patient anxiety of the upcoming dental manipulations. Conclusion: Quality dental services are the basis for the success of the diagnostic - treatment process of any dental practice. Communication with the patient and his relatives is the duty of every dentist, which is of great importance for preserving the mental health of the patient. Great attention is paid to the development of communication skills by dental practitioners. According to a number of studies, effective communication with patients is at the heart of the success of any dental practice. Following some basic rules in communication is a key factor in a good relationship between the dentist and the patient.

In general, people in Indonesia use the electricity purchasing system from the state electricity company in two ways, namely Postpaid and Prepaid. In postpaid electricity subscription mode, the customer uses electrical energy first and then pays the bill the following month. PLN officers must record the meter, calculate and issue accounts to be paid by customers, bill customers who are late or do not pay, and cut off electricity if consumers are late or do not pay their electricity bills after a certain time. This is a weakness in the postpaid system because of the gradual process before the customer finally makes a bill payment. Prepaid electricity is introduced to customers by providing several conveniences, namely being able to control their own use of electrical energy, customers only need to buy vouchers or tokens according to the desired nominal. This is also a form of sales control carried out by PLN because it can reduce the amount of customer receivables, so there is no need for late fees and can also maintain customer privacy by not calculating kWh meters every month. The solar electric system provides a new breakthrough by utilizing solar energy which is then converted into electrical energy. The use of solar energy for electricity generation has actually been carried out for a long time, namely since the early 1980s, but its application is still limited to small power systems or better known as the Solar Home System (SHS). This research has successfully implemented a comparison of postpaid, prepaid and solar energy use. From the test results, it is found that the most economical prepaid system among other systems applied is the postpaid system and the solar power system. The results of tests carried out at the household scale show that during the 10 years of life, the results of using prepaid electricity are 16.6% more efficient than solar panel systems and 17.7% more efficient than postpaid electricity and prepaid electricity is 1.34% more efficient than postpaid electricity
