Classification Of The Nonlinear Dynamics Of Ultrasonically Excited Bubbles And Their Effect On The Acoustical Properties Of The Medium: Theory, Experiment And Numerical Simulations
Authors: Sojahrood AJ
Published: October 2021

Acoustically excited microbubbles (MBs) are the building blocks of several applications as diverse as underwater acoustics to sonochemistry and medicine. MBs are used in numerous diagnostic and therapeutic procedures. MBs dynamics are complex and nonlinear. Moreover, the presence of the MBs in a medium changes the medium’s attenuation and sound speed. The changes are nonlinear and depend on the complex MB dynamics. Within this complexity lies great potential for applications. For instance, the nonlinear response of MBs is used to increase the contrast to tissue ratio in imaging. Achieving the full potential of MBs in applications requires not only understanding the MB behavior, but also a detailed knowledge on the effect of the MBs pulsations on the medium acoustical properties. For instance, increased attenuation due to MBs in the ultrasound beam path limits the focal ultrasound energy which can reach a target. In this work, nonlinear MB dynamics are studied with unprecedented detail over wide ranges of ultrasound exposure parameters. Methods of nonlinear dynamics and chaos including bifurcation diagrams and resonance curves are used to visualize the results. In tandem, the scattered pressure from single bubble oscillations was experimentally investigated. Nonlinear dynamics of the MBs is classified both experimentally and numerically. We show, for the first time, that higher order subharmonic oscillations can be generated at very low acoustic pressures (e.g. 1kPa) in the oscillations of the lipid coated MBs. We address one of the open problems in acoustics by developing a comprehensive model to calculate the nonlinear attenuation and sound speed of bubbly media. Unlike current models, our new model is not limited by any linear or semi-linear approximations. The predictions of the model are verified by comparing it to other simplified models and experimental observations in bubbly media. We show, for the first time, the numerical and experimental evidence of the
pressure dependent sound speed in bubbly media. The nonlinear attenuation and sound speed of
the bubbly media are classified over a large range of acoustic exposure parameters. The classified
regimes are then used to engineer the attenuation of a bubbly medium, during which ultrasound
can pass through a highly dissipative bubbly medium with minimum loss.
On The Development Of Photoacoustic Imaging Biomarkers For Cancer Treatment Monitoring
Authors: Hysi Eno
Published: October 2021

This dissertation describes the development of functional and structural photoacoustic (PA) imaging biomarkers that can be used to monitor cancer treatment response and potentially predict treatment outcome. An imaging method that can indicate individualized treatment success could improve therapeutic outcome. Assessing the effectiveness of therapies as early as possible may spare the patient from unnecessary treatments and save precious clinical resources. In order for PA imaging to enter mainstream radiology and become a treatment monitoring tool, rigorous development of biomarkers that are easy-to-use and representative of the treatment-induced changes in the tumor microenvironment are needed. In this work, I have developed imaging biomarkers that rely on the analysis of the radiofrequency signals in acoustic resolution PA imaging. Specifically, I show through simulations and experiments that biomarkers sensitive to the size, number density and spacing of tumor blood vessels can be extracted through time and frequency domain analysis of PA signals. This information is encoded in the speckle that forms during diffuse optical illumination, which was previously thought to be noise. Moreover, I demonstrate that PA imaging can detect the response of a thermosensitive liposome by measuring a >10% drop in the oxygenation of the tumor as early as 30 minutes post-treatment. This change in oxygenation is due to vascular disruption, a phenomenon that can be detected through frequency analysis of the PA signals. The spectral slope parameter decreases by as much as 73% in 2 hours post-treatment and can be used to differentiate alongside the oxygenation biomarker between responders and non-responders. Lastly, I demonstrate that these PA imaging biomarkers correlate well with the histologically measured biophysical changes of two novel, bubble-based cancer treatments. In this dissertation, PA imaging biomarkers for cancer treatment monitoring are developed, advancing the modality towards clinical translation.
Motion Boundaries Formation For Autonomous Vehicles
Authors: Bannis Joel
Published: October 2021

In this paper, the application of Model Predictive Control to perform curvilinear motion planning is explored. More specifically, nonlinear MPC will be focused on because of its proven efficiency in the modeling of uncertainties as well as in nonlinear model dynamics. The main objective of this report is to show that with proper modeling and formulation of motion constraints, curvilinear motion planning can be achieved with nonlinear MPC. The trajectory of the vehicle will be tracked with the least error while satisfying constraints such as speed and steering angles. Simulations are presented which demonstrate the ability of the suggested models to successfully perform curvilinear motion staying safely within the bounds, while simulations of several models validate its performance. A deterministic sensitivity analysis was conducted in order to determine the impact

of the prediction horizon time. Experimental results show that a critical prediction horizon time approximately 10 to 13 seconds was identified as the ideal range for optimal results of the model.
Statistical Evaluation of the Europe Bridge Between Kehl and Strasbourg According to the “Guideline for the Recalculation of Existing Road Bridges” with Specific Mathematical and Structural Examination of the Cracks in the Superstructure
Authors: Oechsle Leonhard
Published: October 2021

This master´s project re-evaluates the Europe Bridge after 60 years of service. The framework for the calculations is provided by the “Guideline for the Recalculation of Existing Road Bridges”. With the help of a computer model, generated by the program SOFiSTiK, and the prescribed loads of the guideline, the required checks in the ULS were performed at the main load bearing system. As the results indicate a high exceedance of the capacity, different alternatives were evaluated to restore the structural safety.

A specific focus was laid on the assessment of the cracks in a connection of the lateral load bearing system. Initially, a literature research on the crack formation in the superstructure of steel bridges was conducted. The gathered information points towards category three fatigue cracks that were caused by poor fatigue design and a discrepancy between static modelling and execution on site. These conclusions were confirmed by the fatigue checks of the affected connections. However, an analysis of the crack detail with a FE-model of the lateral system shows that the crack has no significant impact on the load bearing behaviour of other components.
Optimization of Reduced Beam Section Moment Connections
Authors: Lawal Morayo Oluwaseun
Published: October 2021

Reduced beam section (RBS) moment connections also referred to as Dog-bone connections
are commonly used in seismic resistant steel moment frames. In RBS connections, the top and
bottom flanges of the steel beam are selectively trimmed in the area adjacent to the beam to
column connection. This is to ensure that under seismic loading, plastic hinges are formed in
the beam not in the column.
The purpose of this study is to optimize the cyclic responses of RBS moment connections
including those with sloping beams. Using a response surface method, predictive equations are
developed for the response characteristics, such as initial stiffness, plastic strain index, moment capacity, hysteretic energy dissipation, and strength degradation rate. The optimization studies
consider objectives leading to higher stiffness, lower plastic strain index, maximum moment
capacity, higher hysteresis energy dissipation and lower strength degradation. The optimization
results obtained shows that beam slope angle greater than 27.8° will experience fracture, high
inelastic demand with higher strength degradation and more intense buckling.
Simplified Approach of Seismic Analysis Using a Planar Linear Elastic Model for an Office Building with no Regularity in Plan in Comparison to a Spatial Model According to Finite Element Software
Authors: Schlenker Timo
Published: October 2021

This master’s project introduces a simplified approach to calculate the earthquake resistance of a four-storey office building. Therefore, the moment distribution of each bracing wall according to the approach will be compared to the moment distribution according to the earthquake resistance calculation of a finite element software. Both, the simplified approach and the calculation using a spatial model will be introduced and performed. The comparison then will be investigated to explain the differences and why the approach can not be considered to be a conservative simplification to calculate the investigated building for earthquake resistance.

Furthermore, this masters project is based on the 2018 German National Annex of Eurocode 8 and compares it to the predecessor version of 2011.
Design of Anchorage in Reinforced Concrete Members
Authors: Kok Hamdi Kaan
Published: October 2021

This project is written in an informative manner and discusses design process, and
requirements with examples for anchors and anchor groups in concrete which are used to
transmit forces to concrete elements by tension, shear, or a combination of the two.
Various different anchor types, such as cast-in place anchors, post-installed anchors,
adhesive anchors, expansion anchors, hooked bolts and undercut anchors are analyzed in this
report. The critical effects of factored loads which the anchors and anchor groups are designed
for, are determined by elastic analysis. Seismic effects which include load combinations with
earthquake effects are out of this project’s scope.

Discussed in this project, the background of theory, analytical analysis, and design
equations provided in this project for determining the performance of a specific anchor have
been calibrated from an extensive database of experimental tests which have been conducted
over the last 30 years. The equations are designed with a 5% fractile failure level from these
tests, meaning that 95 times out of 100, the actual strength of the anchor will exceed the nominal strength which is key in providing a more consistent level of safety for a wider range of
failure modes in both cracked and uncracked concrete.

In addition, this report also provides the design process of the same anchor types
aforementioned, with design equations, in The American Concrete Institute codes. Key
differences and similarities are paid particular attention to and discussed in depth compared to
Canadian Standards in this report.
The Philosophical Conception of Quality in Accountance: A Theoretical Study
Authors:   Zhytomyr Polytechnic State University, Bezruchuk S. L.
Published: October 2021

The quality of information covers a number of its characteristics, and as a philosophical category quality is characterized by relativity, independence from the subject, as the most objective concept. In accountance, this concept is multifaceted and multivariate, which makes it difficult to outline and study the definition. Quality was considered as an internal feature of the subject, its property, a totality of features, etc. The article examined the philosophical interpretation of the concept of «quality» and its evolution in the accounting system, as a result of which it is found that the term «quality» has objective (measurable and calculated) and subjective (those that are evaluated only by each individually) characteristics. The author’s own vision of the philosophical category of «quality» in the accounting system is proposed. The main emphasis is on the objective and neutral nature of the category of «quality», which corresponds to its philosophical basis and allows to distinguish it from the concepts of «level of quality», «usability» and «suitability». There is a transition from the scheme «users – requirements – capabilities of the accounting system – quality» to the scheme «users – requirements – signs – capabilities of the accounting system – quality», and important factors of quality justification are standardization and audit system. Accordingly, in accountance, to ensure such objectivity, it is necessary to create requirements, since the quality, in addition to measurable (objective) features, has purely subjective features (each person evaluates accounting information differently). In order to ensure high-quality reporting, compliance with standards should be mandatory subject to clear regulation on the part of the State, responsible, not a formal approach to obtaining the relevant audit opinion. Not only the theoretical sphere, but also the practice of reporting by enterprises in terms of the characteristics of the category of «quality of reporting» requires further research.

The procedure for computing the integral indicator of competitiveness, which includes groups of indicators that determine the state of the enterprise and the competitiveness of its products, as well as indicators within each group, is considered. The methodology of economic analysis of the level of competitiveness of the enterprise is proposed, which allows to conduct an overall assessment of its competitive position compared to competitors; determine the influence of factors on the difference in their position from the position of competitors; calculate the reserves of growth of the competitiveness indicator and develop measures for their implementation. In accordance with the competitive strategy of the enterprise and the task of increasing the competitiveness indicator on the basis of the use of the provisions of the theory of economic efficiency, a list of measures is substantiated, the practical implementation of which will allow to perform the task with a minimum amount of resources. Operational control over the implementation of measures and their impact on the competitiveness indicator is envisaged in order to make corrective managerial decisions in a timely manner.
JAGUAR AND PUMA IN BRAZILIAN SEMI-ARID REGION – SCAPEGOATS FOR WEAK GOVERNANCE?
Authors: Martins Cláudia Sofia Guerreiro , Schulz Francine , Esteves Carolina Franco , Marchini Silvio
Published: October 2021

Exclusively Brazilian, the Caatinga is a seasonally dry tropical forest where the endangered jaguar (Panthera onca) and puma (Puma concolor) co-occur with the lowest regional Human Development Indexes. New land uses challenge traditional livelihoods and add threats to species historically poached in retaliation for livestock depredation. Chronicle biodiversity conflicts became acute after a reported increase in depredation allegedly because of those changes and conflicts among stakeholders. Using the framework of human dimensions of wildlife management, pioneer research on the vulnerabilities of rural communities to jaguar-and-puma conflicts was led in ‘Boqueirão da Onça’, within and surrounding that polygon of protected areas. The aim was to identify, describe, understand, and predict human behaviour, and link the outcomes with the IUCN natural resources governance concept. Negative attitudes arose from 72% and 35.2% participants towards the proximity of jaguar and proximity of puma, respectively. When asked about institutions working for wildlife protection, and institutions working for people facing problems caused by carnivores, 64.9% and 88.8%, respectively, were unaware of them. Regarding beliefs about co-occurrence with jaguars or pumas, 80.9% and 82.9%, respectively, mentioned more problems than benefits, with 74.5% believing in the increase of both species’ populations due to the creation of protected areas. This scenario may ease jaguar and puma to become scapegoats for human-wildlife and broader social conflicts, unless values such as justice and transparency are pursued.
SUSTAINING LIFE WITH TREES: ECOCRITICISM PERSPECTIVE IN SELECTED PICTURE BOOKS
Authors: Tisnawijaya Christy , Kurniati Geni
Published: October 2021

The issue of the environmental problem has been prevalent especially in the contemporary era. The fact that Mother Earth is currently facing a lot of environmental concerns is the central discussion of the selected children’s picture books. Hence, this study aims to analyze how the picture books successfully capture the idea that trees are the symbol of Mother Earth per se. The selected picture books to be discussed are: A Tree is Nice by Janice May Udry (1984), The Giving Tree by Shel Silverstein (1992), Red Knit Cap Girl and The Reading Tree by Naoko Stoop (2014), Seasons Come, Seasons Go: Tree by Patricia Hegarty (2015) and The Tree by Neil Layton (2016). By scrutinizing the narrative and illustrative elements of the picture books, this study sheds light on how the ecosystems are held together by trees. The trees play a vital role in balancing and maintaining the world’s ecosystems. Moreover, the trees are valuable for providing environmental and social benefits. Hence, taking care of the trees can be perceived as maintaining a sustainable life for both the living and nonliving things. The underlying theories to support the discussion are those of ecocriticism, narrative and illustrative elements, and the trees as metaphor of Mother Earth, all of which are interconnected in children’s picture books.

Thus, this paper explores the linguistics landscape of culinary signs around campus in Malang, East Java, Indonesia, the melting pot of cultures and languages. The research aims to analyze the form of language use and its function. The data collection is photographing culinary signs around three advanced campuses in Malang, namely the University of Brawijaya, State University of Malang, and the University of Muhammadiyah Malang. Qualitative descriptive was used in analyzing the data. The results showed that Indonesian, English, and Javanese are the most frequent languages used in culinary banners or storefronts and other foreign languages (Japanese, Korean, Arabic, Malay) and vernaculars (Sundanese, Banjarese, Minangnese). It was found that the Malang culinary linguistics mirrored the taste and service of the store. Furthermore, foreign languages are becoming a way to go global and known by college students who most like modernization. The use of Javanese also acts as a symbol of maintaining the cultural heritage of Javanese people.

Published: October 2021

Pressure fire hoses are one of the main types of fire-fighting equipment, on the serviceable condition of which depends the operational activities of fire and rescue units and successful firefighting.
At present, Ukraine has entered into force with (01.08.2021) the national standard, which contains modern European requirements for assessing the quality of flat-hose fire hoses for fire and rescue vehicles. This standard was developed by the Institute of Public Administration and Research in Civil Defense in the framework of research work "Fire hoses – test methods" and adopted by order of SE "UkrNDNC" from 23.03.2021 № 107.
In order to assist in solving this problem, the Institute of Public Administration and Research in Civil Defense put into operation, tested and verified the installation for testing fire pressure hoses, which will check the quality of pressure flat hose for fire and rescue vehicles in accordance with modern European requirements.
The installation is intended for tests of pressure fire hoses carried out on the following quality indicators: working, test and burst pressure; abrasion resistance; resistance to hot objects; resistance to open flame.
The unit is operated at air temperature from 10 ° С to 25 ° С and relative humidity from 15% to 90%.
The installation is a metal table, which consists of two levels (upper and lower).
The main part of the tests is to be performed at the upper level with the help of three removable modules. The lower level provides one stationary module on which tests for working, test and burst pressure are carried out.
The upper level of the installation is designed to test pressure fire hoses for the following quality indicators: resistance to surface abrasion, resistance to point abrasion, resistance to hot objects and resistance to open flames. For versatility and convenience of work on installation on the top level of a table the possibility of change of modules depending on their need is provided.
The lower level of the installation is intended for carrying out tests of pressure fire hoses on quality indicators – working and test pressure, bursting pressure. At the lower level of the metal table is a rectangular metal box, which has a closing lid. During the tests, the sample of the test sleeve is automatically filled with water, which drains after the test. To fix the samples of fire hoses of different diameters (25, 32, 38, 51, 66, 77, 100, 125 and 150) mm, the installation includes special cones and plates.
INVESTIGATION OF RISKS OF INSURANCE OF ACCIDENTS AND TRAUMATIC EVENTS USING THE COMPONENT METHOD
Authors: Hubachov O. , Sukach S. , Chencheva O. , Tsybulnyk N.
Published: October 2021

The article is devoted to the problem of researching the levels of risks of insurance accidents and traumatic events using the component method. The study used data from the Social Insurance Fund of Ukraine on the content of the causes of insured accidents and types of traumatic events for the period 2017-2020. The existing system of labor protection management at the state and production levels in Ukraine is not effective enough and requires the selection of objective and effective methods for determining the quantitative characteristics of industrial risk. The main requirement for the results of quantitative assessment of industrial risks is the objectivity of the information provided on emergency situations. The study of the causes of incidents and the development of recommendations for reducing occupational risks for workers were performed. To increase efficiency, it is proposed to use the component method. The essence of this method is to compare the assessment data with the determination of the risk of traumatic event on the basis of averaging the distribution of risk on the indicators of risk-relevant information.
The study shows the universality of the component method of determining the levels of risk in enterprises of different industries, profile, level of automation, production volumes. The use of a component method for assessing the risk of traumatic events allows you to quantify the indicators of risk-relevant information and determine the distributed levels of industrial risks of 18 types of traumatic events. By comparing the risk distribution data obtained by the modified matrix and component method, it is shown that when the component method is used, the risk is distributed more evenly and closer to the causes of real injuries due to the leveling of such factors as subjectivity.
The study of the risks of insurance accidents and traumatic events using the component method showed a different picture: an increase in the share of organizational causes and a decrease in the share of psychophysiological and technical reasons, a decrease in the share of major events in general. This is observed against the background of declining industrial production and indicates a relatively high degree of wear and tear of means of production (machines, production lines, mechanisms), weak motivation of workers for personal safety, which requires improving the legal framework for occupational safety, introduction of progressive forms of compliance standards for parameters of microclimatic conditions in the work area - automation (temperature, dust, noise, vibration, concentration of hazardous and harmful substances). This will have a positive effect on the psycho-emotional state of employees.

Published: October 2021

Current trends in ensuring sustainable business development are based, inter alia, on the diversification of the workforce. Provision with the workplaces to people with disabilities allows the company gaining many benefits due not only to compliance with the legislation, but also to improve the management system of opportunities to implement projects on corporate social responsibility. Taken together, this allows the company demonstrating its strengths, gain competitive advantage and investment attractiveness. The downside of this issue is the possible additional investment in adapting the workplace to the needs of worker with disability and an increased risk of injury. Occupational safety, as a powerful system of organizational and technical measures, allows not only minimizing the costs of business to ensure the employment of people with disabilities, but also to help implement programs of corporate social responsibility. The article analyzes the role of occupational safety in the implementation of projects on corporate social responsibility and presents the results of a survey of stakeholders on the problems of employment of people with disabilities in the organization. It is shown that negative expectations of employers about the possible increasing of injuries, as well as the need for additional investment to adapt workplaces to the special needs of people with disabilities, even with an understanding of the importance of this issue and positive impact on company development create obstacles to development of this area. An effective solution to this issue is to intensify the company's efforts to improve the management system of occupational safety and the use of powerful tools of organizational and technical measures to adapt the workplace and work process to the needs of socially vulnerable groups.

Published: October 2021

The article considers the problem of efficiency and safety of fertilizers using in agriculture. Fertilizers are an integral part of the food fund formation system, which determines food safety at the national and world levels. Thus, the research of the safety state of fertilizers handling is an actual practical task in the context of sustainable development of society. The aim is an analysis of the efficiency of fertilizer using in agriculture, determining the level of fertilizer safety for the environment, human health and working conditions. Organic and mineral fertilizers are the most widespread in agriculture. Fertilizers are one of the main factors in improving the quantity and quality of agricultural products. The rational usage of fertilizers helps to maintain the nutrients and humus balance in the soil, to improve its fertility. The organic fertilizers include organic compounds of animal, vegetable, industrial and household origin. They have different decomposition degrees and create different nutrients complexes (nitrogen, phosphorus, potassium and others), which are well absorbed by plants. The danger of organic fertilizer usage is associated with the possible presence of bacteria, viruses, parasites, antibiotics, steroid hormones, pesticides in their composition. The release of these agents into the environment disturbs the ecological balance of the soil and degrades its quality, pollutes water, contributes to food epidemics, causes chronic diseases and acute poisoning in humans. Mineral fertilizers are artificially synthesized chemical compounds that are needed to maintain the inorganic compounds balance in the soil. Irrational usage of mineral fertilizers leads to changes in soil composition and properties, disruption of nutrients natural cycles, pollution of the environment and agricultural products by nitrates, heavy metals, halogens and radionuclides. All this negatively affects the quality of human life and health. In addition, improper fertilizer handling during production, storage, transportation and usage worsens the working conditions, leads to occupational diseases, increases explosion and fire levels. It is necessary to optimize forms, rates, timing and methods of fertilizers application, adhere to treatments frequency and distance from settlements, adhere to labour protection norms, rules and instructions and apply collective and individual protection means during fertilizers working.

Enterobacter cloacae forma parte de la microbiota intestinal en humanos, pertenece al phylum de las Proteobacterias, familia Enterobacteriaceae, género Enterobacter, especie E. cloacae; se caracteriza por ser ubicua, oportunista, fármaco-resistente y responsable de bacteriemias e infecciones nosocomiales, por lo que se hace necesaria la búsqueda de alternativas para su tratamiento y control. En este trabajo se muestra evidencia de la inhibición del crecimiento de E. cloacae empleando metabolitos bacterianos o sobrenadantes libres de células (también conocidos como postbióticos) producidos por Bifidobacterium longum (probiótico que pertenece al filo Actinobacteria); varios trabajos demuestran la importancia de estos para inhibir el crecimiento de diversos microorganismos patógenos. En este trabajo se evaluó el liofilizado de los postbióticos de B. longum, observándose un 99% de inhibición de E. cloacae en cultivos in vitro. Estos resultados se suman a las diversas investigaciones con probióticos encaminados al tratamiento y prevención de infecciones ocasionadas por E. cloacae.

The professional culture of an English teacher as a systemic characteristic and activity of a foreign language teacher's personality, which is an integral unity of such interrelated and interdependent components as need-motivational, activity-personal, organizational and creative,  are considered in this article. The aim of the research is to substantiate theoretically the spiritual foundations and pedagogical conditions for the formation of the professional culture of future English teachers in the higher education system. The professional culture is considered as the way in which teachers develop their activities in educational institutions. Among the indicators that can be used to characterize the spiritual foundations of professional culture of an English teacher, the following are distinguished: the level of assimilation common spiritual values and culture; the nature of choice and the level of participation personality in the production of spiritual values, in the development and consumption of spiritual wealth; orientation of motives for participation in the creation and consumption of spiritual values; the level of education, qualifications, cultures of thinking, feelings and behavior. The components of professional pedagogical culture: axiological, technological and personal and creative are analyzed.

The strategic provisions of the concept of academician G. Shevchenko on the importance of education and upbringing, which should fulfill the most important mission of the current civilization – to form the “Spiritualized Image of Man of Culture of the XXIst century” in the younger generations are used. The professional culture of an English teacher is determined as a systematic characteristic and activity of the personality of a foreign language teacher, which represents the integral unity of such interrelated and interdependent components: need-motivational, activity-personality, organizational and creative. The structural components of the professional culture of a future English teacher are characterized.
ТЕХНОЛОГІЇ ВИХОВАННЯ: МІЖНАРОДНІ ТА ВІТЧИЗНЯНІ ОСВІТНЬО-ВИХОВНІ ПРАКТИКИ
Authors: Лучанінова О. П.
Published: October 2021

Через пандемію, швидку зміну технологій, глобалізаційні виклики сьогодні вища школа переживає гуманітарну кризу. Це негативно впливає на підготовку висококваліфікованих фахівців, формування у них ціннісної свідомості, творчого мислення, національно-культурної ідентичності, громадянської відповідальності. Такий підхід ставить під загрозу виконання завдання навчити студентів толерантності, здатності мислити, аргументувати філософськими та духовно-культурними категоріями, вибудовувати свій шлях саморозвитку професіонала й освіченої, культурної особистості. Актуальними є проблеми виховання духовно пробудженої особистості, сприяння міжкультурному діалогу та залучення молоді до побудови мирних і відкритих для участі суспільств, заохочення до творчості та різноманітності форм культурного самовиразу задля забезпечення сталого розвитку. Вітчизняні ЗВО не мають необхідну кількість ефективних спецкурсів, соціально-гуманітарних і культурологічних дисциплін, які б сприяли вирішенню цих проблем. Разом із тим педагоги-вчені й практики зі всього світу та України зокрема мають низку наробок щодо технологій виховання, застосовують освітньо-виховні практики у процесі професійної підготовки студентів.

Автор наголошує, що з-поміж наукових та практичних наробок у вихованні студентів вищої школи виокремлюються питання соціальної відповідальності, формування громадянських компетентностей, громадянська освіта, соціальні й громадянські  навички, виховання через освіту тощо. Нарівні з умінням бути культурною, гармонійно розвиненою особистістю постає відповідальність як ключова компетентність у вищій освіті. Саме відповідальна, толерантно вихована особистість майбутнього фахівця є запорукою духовної безпеки будь-якого суспільства. Досвід виховних досліджень і практик європейських та українських вишів є дуже цінним. Актуальними є форми і методи розвитку соціальної відповідальності студентів, їхня громадянськість, морально-культурні цінності, духовна безпека, лідерство в студентському середовищі, засоби заохочення студентів до громадянської активності, роль освітнього середовища, оновлення виховної системи закладу вищої освіти та його освітніх сервісів. Духовне пробудження особистості  у добу глобалізаційних викликів може відбутися тільки завдяки прийняттям нею громадянських цінностей через культуру й соціальну відповідальність. Сьогодні в українських вишах відбувається не тільки професійна підготовка студентів, а й генерується суспільна ідеологія
МЕТАФОРИЗАЦІЯ ДУХОВНОГО РОЗВИТКУ ОСОБИСТОСТІ У ВИЩІЙ МИСТЕЦЬКІЙ ОСВІТІ
Authors: Олексюк О. М.
Published: October 2021

У статті обґрунтовано авторський підхід до проблеми метафоризації постнекласичного освітнього процесу у вищій школі. Опора на метафору стає альтернативною традиційній педагогіці з метою її переорієнтації на людиноцентрованість.

Метафоризація освітнього процесу має безпосереднє відношення до механізму мислення: вона є його невід’ємною частиною. Метафора розглядається як частина когнітивних процесів, що уможливлює шлях від сприйняття художнього образу до формування концепту.

Підкреслено, що метафора дає змогу позитивно оцінювати організацію освітнього процесу. Метафоричне мислення розглядається як мислення на основі руху від конкретних об’єктів до розуміння ціннісних ідей та їх асоціативних зв’язків.

У статті наведені приклади завдань, пов’язаних з діагностикою та розвитком ціннісних орієнтацій студентів закладів вищої мистецької освіти. На основі аналізу сценарію сторітелінгу  «Ми вдвох однією журились журбою, і щастям раділи одним…» показані можливості апробації метафори у змісті мистецької освіти. Аналіз виконаних завдань засвідчують факт доцільності переорієнтації освітнього процесу, організованого в дусі постнекласичної педагогіки. У здійсненні проєкту, що охоплює різні види мистецької діяльності, залучені інтелектуальні та творчі сили викладачів і студентів. Зазначено, що, керуючись нелінійною логікою, ми отримуємо головний продукт творчості студента – його особистість, з якою здійснюється перехід від образу до концепту (образ-метафора-символ-концепт).
