Published: June 2022

This article discusses the distance learning problem in connection with COVID-19 limitations and isolation duration from the point of view of students’ psychological safety. This article analyzes the main psychological characteristics of distance learning technologies and their implementation during the pandemic. Distance education's positive and negative aspects in specific conditions are highlighted in detail. This study was conducted among 200 participants using a request for mental and physical change in online education conditions and their impact on feelings of psychological safety. The participants were divided into two comparative groups, considering the conditions of online education provision. The first group included 83 respondents who were provided with fully-fledged conditions, while the second group included 117 respondents with less secured conditions. In the context of the COVID-19 pandemic, one of the security constraints was fatigue in front of the computer for a long time, while the others were boredom and some discomfort due to adaptation to the new standard of education for both the teachers and students. Online education provides an opportunity to save time and money by teaching in the same environment, which also ensures the stability of the activity.

The study’s primary goal is to determine the philosophical and legal foundations of the formation of the legal consciousness of an individual in the conditions of training a lawyer. Modern society is changing, transforming into a European-style society, and rethinking the laws of life is necessary for every person. Awareness of the changes in society, the role, place and significance of legal norms determine the changes in a person’s consciousness, and therefore the issue of legal consciousness of a person arises especially acutely. The study of the phenomenon of human legal consciousness has significant scientific and practical value since it will solve several issues related to the development of the state, the further formation of European society and the participation of citizens in law-making will contribute to solving problems related to legal education and provision. As a result of the study, the main aspects of the philosophical and legal foundations of the formation of the legal consciousness of an individual in the conditions of training a lawyer were identified.
Identification of Hedging Strategies in Business Negotiations
Authors: HARUTYUNYAN Lusine , BAGHRAMYAN Ruzanna
Published: June 2022

The way people conduct business negotiations has altered immensely over the past decades to adapt to the ongoing changes in business environment. Innovative strategies have been orchestrated to overcome the challenges as well as meet the prerequisite requirements of contemporary businesses. The ultimate goal of such effective strategies is the maintenance of courteous relations among the negotiators and the achievement of a mutually beneficial outcome. In this respect, vague language or fussy language is regarded as a sui generis negotiation strategy that is prevalently exploited by negotiators with the intention to make the communication process smooth, polite and cooperative. Vagueness in a language is expressed through hedges, the semantic and pragmatic features of which are inextricably linked. The scope of this research shapes a profound pragmalinguistic analysis of hedges, which engender divergent negotiation strategies (detachment, agreement, complimenting, vagueness, etc.), its functions and roles in business negotiations. In addition to its linguistic significance, hedging is a widespread practice in a risk management strategy to offset losses against the risk and protect the investments. Obviously, on both occasions, business people pursue the following goals: at least reduce the chances of failure or minimize further complications, and, at most, obtain the desired result.
Transformation of the Phenomenon of Friendship Through the Prism of Network Technologies
Authors: STEBELSKA Oleksandra , PANKIV Olesia , ONYSHCHUK Oksana
Published: June 2022

The article attempts to determine and clarify the concept of ‘friendship’. In particular, it focuses on the prime aspects of the concept and their transformations due to the usage of modern network technologies. The research is based on the semantic analysis of friendship's biological, ontological-axiological, and social aspects. It argues that the integrative function of friendship, which determines its biological aspect, enhances the network contributing to more effective solutions to people’s problems. The ontological-axiological aspect reveals selectivity and fragmentation in manifesting the concept under analysis. The social aspect shows formal and superficial features of friendship in the network. It is stated that the network reduces the prime ontological status of friendship, resulting in changes in a person's biological, moral and social principles.

Published: June 2022

Social order and stability depend on many social factors, among which social control occupies an essential place as a means of self-regulation of society, the purpose of which is to streamline social relations. This problem is especially acute in the legal plane, where control is used together with other social and legal means as a decisive factor in forming the legal order. A philosophical and legal study of control and its impact on the rule of law requires a detailed examination of these concepts in historical retrospect through the prism of their value-based content. The study's primary purpose is to determine the main features of the philosophical paradigm of control in the context of the philosophy of law. The primary methodology was several historical and theoretical methods of analysis and research, which made it possible to achieve the set goals. As a result of the study, the critical elements of the philosophical and legal paradigm of control in the context of the philosophy of law were identified.

The purpose of this research in general is to find out the Marketing Strategy of Garuda Training and Outbound Training Institute Services to Increase the Interest of the Muslim Community. In detail, this research seeks to get a clear picture of:

1) Marketing Segmentation, 2) Marketing Budget, 3) Marketing Budget, and 4) Marketing Mix. The method used in this study is a descriptive method with a qualitative approach. The sources of data in this study are the Director, Operations Manager, Finance Manager, and Consumers of the Garuda Training and Outbound Training Institute. Data collection techniques used by researchers are in-depth interviews, participant and non-participant observation and documentation.

In general, the results of this study conclude that the service marketing strategy carried out by the Garuda Training Institute is quite good in accordance with marketing management theory. However, there are still some shortcomings, namely in terms of time management of members. Specifically, it can be explained as follows. First, the market segmentation that has been carried out has implemented accessible groups and also differentiates these market segments by region (geography). However, the Garuda Training Institute does not divide its market segments based on demographic specifications (religion, age, gender, education level, etc.). Second, the Budgeting carried out by the Garuda Training Institute does not apply the exact amount in its budget because it adjusts from the income of previous activities and will be used for future marketing. Third, conduct marketing timings through social media only at the beginning and end of the year. Because their market segment is from the Department and Agencies. Fourth, offer the program very clearly because it lists what the program is. The prices offered are friendly to consumers' pockets and consumers can also participate in discussing prices with the Institute. The place to do marketing is also clear, namely partnering with the Bajau Hotel which is located right at the tourist spot. Promotions carried out by the Institute use promotions through social media, relations and brochures in places that are partners with the Garuda Training Institute.

Streszczenie

Mleko surowe, które nie zostało poddane obróbce termicznej, może być ważnym źródłem drobnoustrojów chorobotwórczych przenoszonych drogą pokarmową, głównie takich jak: patogenne szczepy Escherichia coli, bakterie z rodzaju Salmonella, niektóre paciorkowce kałowe czy Listeria monocytogenes. Najgroźniejszym z patogenów związanych z surowym mlekiem jest E. coli VTEC, która wytwarza werocytotoksyny – zwłaszcza szczep O157:H7. Enterococcus spp. jest jednym z czynników zapalenia wymienia u krów i dlatego często występuje w surowym mleku, co może stanowić zagrożenie dla konsumentów. Spożywanie mleka surowego jest dobrym wyborem, pod warunkiem, że mamy gwarancję wysokiego poziomu higienicznego jego pozyskiwania.

Synthesis and characterization of TiO2 films sensitized with chlorophyll and metal-chlorophyll complex (M=Zn2+, Co2+) were carried out. Chlorophyll isolated from cassava leaves shows absorption peaks on the UV-Vis spectra in the Soret band area (415 nm) and Q band area (665 nm). The metal-chlorophyll complex was prepared from the reaction of the isolated chlorophyll and ZnCl2 (for Zn2+-chlorophyll); CoCl2.6H2O (for Co2+-chlorophyll) under reflux condition at 65 ºC with a mole ratio of 1:1. The UV-Vis spectra of the isolated products showed a hypsochromic shift to 410 nm and 660 nm for Zn2+-chlorophyll whereas the spectrum of the Co2+-chlorophyll product demonstrated the shifts to 403 nm and 661 nm. These hypsochromic shifts are proposed to be a metal-to-ligand charge transfer (MLCT) transition as a result of chlorophyll metalation. The FTIR spectra of chlorophyll and metal-chlorophyll complexes have a similar pattern despite changes in the absorption of vibrational energy in several functional groups. The absorption of the C=N group shifted from 1372 cm-1 to 1368 cm-1 for both of the complexes, the C=C group of aromatic shifted from 1451 cm-1 to 1447 cm-1 (Zn2+-chlorophyll) and from 1451 cm-1 to 1445 cm-1 (Co2+-chlorophyll), and the C=O group of ketones shifted from 1627 cm-1 to 1645 cm-1 (Zn2+-chlorophyll) and from 1627 cm-1 to 1646 cm-1 (Co2+-chlorophyll). The shift pattern of the absorption peaks on the FTIR spectra indicates the coordination of metal ions towards the N atom in the pyrrole ring in the porphyrin structure of the chlorophyll. When the isolated chlorophyll as well as the chlorphyll complexes was sensitized on the surface of TiO2, variation of bandgap energy was observed. The calculation using the Tauc Plot method resulted in the bandgap energy of films of TiO2 at 3.20 eV, TiO2/chlorophyll at 2.97 eV, TiO2/Zn2+-chlorophyll at 2.87 eV, and TiO2/Co2+-chlorophyll at 2.90 eV

Fly ash is one of the combustion residues from coal-fired power plants which is produced in large quantities. The main elemental composition of fly ash is silica and alumina with content of 48.055% and 14.653%, respectively. This study aims to determine the characteristics of zeolite A synthesized from fly ash with various ratios of SiO2 and Al2O3. Zeolite A was synthesized using the alkaline hydrothermal method by varying the Si/Al molar ratio of 0.8 1 and 1.2. The initial process begins with the leaching process of fly ash waste and is followed by alkaline smelting. Furthermore, zeolite A was synthesized by adding sodium silicate and sodium aluminate to form a white gel. These steps were followed by a hydrothermal process using a hydrothermal autoclave at a temperature of 100֯C for 5 hours. Qualitative results on XRD showed that zeolite A synthesized at a ratio of Si/Al 1,2 had a 2ϴ position closer to standard zeolite A, which was seen based on the highest peaks at 2ϴ=12,420, 16,070, 20,360, 21,590, 23,960, 26,070, 27,080, 29,910, 32,500, 41,480, 44,090, 52,540, 54,230 and 66,660 and the structure formed is in cubic form with a crystallinity of 76.36%. Analysis using XRF showed that the Si/Al 1.2 ratio was the best for the formation of zeolite A. In this variation the silica and alumina content increased by 54.412% and 35.054%, respectively

The research is intended to analyze whether there is a correlation between students’ vocabulary mastery and cognitive learning style with their reading comprehension ability. Methodology: It was conducted in Muhammadiyah Vocational school Bandar Lampung. The sample comprises 30 students using random sampling technique. A questionnaire was used to trace students’ cognitive learning strategy, and two sets of tests were used to measure students’ vocabulary mastery and another to measure their reading ability. The instruments were tried out to determine the quality of validity, reliability, level of difficulty and discriminating power. The findings: It has been found that, first, there is a correlation between vocabulary mastery (X1) and reading comprehension (Y), where rx1.y = 0.35; second, there is a correlation between students’ cognitive learning style (X2) and their reading ability (Y). where rx2.y = 0.95, it is very strong correlation: and finally, there is a composite correlation between X1, X2, and their reading ability (Y). Multiple regression is 0.997 meaning that there is a positive and significant correlation between X1, X2, and Y. It suggests that to improve reading ability, teachers should develop students’ vocabulary mastery and cognitive learning style. Cognitive learning style and vocabulary mastery cannot be separated.

The body and foundation soil are considered as homogeneous isotropic and anisotropic materials and the effects of horizontal drainage length and cutoff wall on seepage are investigated. The differential equation governing the response of water in the soil is obtained with the help of Darcy's law and continuity equations. A program has been prepared in Fortran programming language to find the hydraulic load, pressure values and phreatic line pressure values at the points inside the dam body and the quantity of seepage on the bottom of dam. It has been shown that the obtained values are in good agreement by comparing them with the results of existing studies in the literature.

Since the beginning of the pandemic, the home insurance sector has suffered from various difficulties. One of the most important difficulties was assessing the damages in the insurance owners’ homes. Due to the current pandemic, letting the experts assess the damages in place is a life-threatening risk. Therefore, the idea of automatically assessing the damage is born. This study aims to create a full report for home damages using Convolutional Neural Network (CNN) and various large deep learning model architectures such as EfficientNet, ResNet, U-Net, or Feature Pyramid Network (FPN). Multiple models for tasks such as binary classification and instance segmentation were developed to create an end-to-end reporting pipeline. In more detail, the pipeline consists of two binary classification models and a segmentation model. Binary classification models are responsible for detecting if the picture is indoors and if there is a wall in the picture, whereas the instance segmentation model is responsible for segmenting the damaged parts of the wall class. The effectiveness of the pipeline was measured using different metrics for each task, including accuracy, F1, dice, and Intersection over Union (IoU) scores. The data for each task is labeled by hand and fed to models. The results show that the constructed pipeline can successfully classify and segment the given images according to the needs of our project. The project will affect the home insurance assessment procedure and time spent tremendously by automatizing these repetitive processes.

The presence of the oscillating motion in a mechanical system, is vital in terms of the service life. Because the machine elements are under effect of fatigue due to the oscillating motion. The service life of the bearings which are in the forefront among the machine elements subjected to oscillating motion, can be calculated via an equation that depends on several variables, one of which is basic dynamic load rating (C). In this context, basic dynamic load rating (C) is one of the most important factors on estimating the service life.

One of where bearing applications used in, is universal joint of driveshaft. A bearing on a universal joint consists of needle roller elements having larger contact area compared to the ball elements. Universal joint bearing is mounted in a bore on a component called yoke part, and so yoke part supports the bearing. In the calculation of basic dynamic load rating for universal joint bearing, effective length of the rolling element is the key factor. In this paper, a new approach to determine the effective length of rolling element used in closed end needle roller bearings of driveshaft has been investigated analytically and the effect of the said approach on the basic dynamic load rating and bearing life has been revealed in terms of ISO 281.

Automotive lighting products, such as Head Lamps (HL), Fog Lamps (FL), Daytime Running Lamps (DRL), face with mechanical vibrations during service life which may coincide with the resonance frequencies of the light source. When excited at resonance frequencies, especially in the case of HL’s, light beam cut-offline may deteriorate and vibration of light beam occurs. This situation is also called light flickering. This state has disturbing effect on the driver’s visibility, which is valid for both the driver and the counter drivers. Most of the automotive manufacturers have developed test specifications for evaluation of flickering state under sinusoidal frequency sweep acceleration loading and they have introduced limits for flickering angle range or displacement range of the light beam with respect to frequency measured on a screen which is put on a prescribed distance from the light source. In this study a traditional way of light beam flickering angle deviation measurement method of HL is presented. Furthermore, application of precise & efficient way of measurement method by the use of quartz rotational accelerometer is inspected.

Purpose: This paper aims to shed light on the issue's prospects, as ethics in Islamic banking may become another distinguishing factor when compared to its conventional counterpart. This comparative research will compare co-operative banks that emphasize ethical operations to Islamic banking in Pakistan. Although ethics in other countries' co-operative banks has become a new market segment and succeeded because it drew many new customers who wanted to engage in a morally sound investment, Islamic banks continue to concentrate only on sharia. Design/Methodology/Approach: The qualitative method is used in this study by analyzing statutes, particularly Islamic jurisprudences, local and international protocols, conventions, and treaties Findings: In this work, it shows that ethics has the potential to make Islamic banking a full-fledged financial system if it is used as one of Islam's three pillars. Implications/Originality/Value: In the Islamic economy, Islamic banking is unquestionably at the forefront. Along with Faith (Aqidah) and Islamic Legal Jurisprudence (Sharia), Ethics (Akhlak), as in corporate social responsibility, is a core part of Islam that doesn't get as much attention as it should. An Islamic bank should primarily concentrate on sharia despite balancing those three pillars. In practice, a business with a high ethical standard must be profitable, legal, honest, and ethical while also considering long-term sustainability.

Economic development acquires a qualitatively new character due to the active implementation of innovations in working processes. Innovation process is a factor of economic growth, which contributes to the transition of a market economy to an innovation-oriented type of economic development. The innovative type of economic development is characterized by expanded reproduction, which contributes to the modernization of economic systems. The transformation of scientific approaches to innovation management goes through successive stages of its development. The implementation of scientific concepts in management processes contributes to the formation of a unified model of innovation management. Today, public administration of innovative development in the economy is rather important. One of the priority areas of state regulation is import substitution in high-tech industries. The main aim of state bodies is to provide comprehensive support to enterprises operating in high-tech industries. Digital transformation is one of the priority areas for improving the state innovation policy. Innovative management methods based on digital solutions contribute to technological development and improve the financial results of companies. The innovation process is implemented through the results of scientific research, which are the basis for the production and sale of products with a high content of technological innovations. During the process of developing innovative strategy for the domestic economy, it is significant to reflect some problems that are related to the import dependence of exporters of innovative products under the sanctions regime. Innovative development is the main factor in the success of companies in an unstable economic environment. Strategic decisions of companies should develop innovative potential, which includes innovation both in production and marketing terms. In the conditions of an unstable external economic situation, ensuring the economic security of the country and the competitiveness of domestic companies is achieved through the implementation of scientific approaches of public administration of innovative economic development.

The main purpose of the article is to study the effectiveness of the implementation of measures in the field of development and management of the forestry complex in certain foreign countries. The research methodology was based on the study of the international experience of individual countries in the development and management of the forestry complex, as well as the systematization of the best foreign practices in this area. In the course of working on the article, the authors used both theoretical (analysis, synthesis, analogy, generalization) and practical (comparison, observation, description) research methods. The analysis carried out in the course of the study showed that in countries with successful experience in the development and management of the forestry complex, countries have a clear delineation of forest management functions at all levels of government. At the same time, efficient forest management is based both on multi-purpose strategic planning and is accompanied by constant monitoring and inventory of forests, which, in turn, contributes to more efficient and timely implementation of measures aimed at maintaining sustainable forest management. The conclusions and analytical generalizations made by the authors based on the results of the study can be applied in practice in the process of improving the existing forestry management system in Russia. The theoretical and practical significance of this article lies in the systematization of the best foreign practices in the development and management of the forestry complex, which provides opportunities for further theoretical study of key aspects of state policy in the area under study. In addition, the results of the study and practical recommendations developed by the authors of the article can be used by public authorities to improve the existing forestry management system in Russia.

The relevance of scientific substantiation of the programs of socio-economic development of the regions is explained by the need to ensure both the activation of economic activity and economic growth, with the coordination of the extensive practice of the tasks of social practice to be solved. For North Ossetia-Alania, an individual approach to the search and implementation of new opportunities in each of the areas of economic activity, with simultaneous programmatic consideration of the adoption of complex regulatory decisions, is of paramount importance. In the scientific literature there is a significant number of works devoted to the justification of program approaches to the choice of goals and objectives that are embodied in regional programs of socio-economic development. At the same time, there is a demand for greater identification of the specifics of individual decisions, including through the systematization and choice for implementation of activities that are justified (including on a calculated basis) to achieve the general goals of an individual program of socio-economic development. In a broad sense, activities for ongoing projects of sectoral and general economic significance for the region must meet the requirements of not only financial costs, but also their effectiveness. The article summarizes the factors and conditions for the implementation of the individual program of North Ossetia-Alania, both in the current and strategic dimensions.
