THEORETICAL BASIСS OF PROVIDING THE TECHNICAL CHARACTERISTICS OF MILITARY AND CIVIL VEHICLES BY JUSTIFICATION OF THE FORM AND PROPERTIES OF THE MATERIALS OF CONTACTING ELEMENTS

Elements of constructions of modern military and civil vehicles usually work in conditions of high contact loads. Аt the stage of their creation, strength studies are carried out using traditional models of contact of bodies of nominal shape. Нowever, the real structural elements have deviations from such models, which are due to design and technological factors: macrodeviation of the shape, surface roughness, strengthening etc. Such perturbations of nominal parameters have a significant effect on the distribution of contact pressure between the elements of military and civil vehicles, however, traditional methods for studying the stress-strain state of contacting bodies do not make it possible to take such factors into account fully, collectively and exhaustively. To eliminate the existing contradiction, a semi-analytical method is proposed, which is based on the development of variational principles and boundary-element sampling. The created models make it possible to take into account the regularities of the influence of shape perturbations and properties of the surface layers of contacting bodies on the stress-strain state. As a result, it becomes possible to justify favorable perturbations by strength criteria. Such models and methods are offered to the work, and on their basis it’s proposed the implementation of research elements of military and civil vehicles for appointment to ensure world class the technical and tactically technical characteristics.

Health and Land-Use Courses of Action for Education for Sustainable Development in Madagascar: Teacher Perspectives on Possibilities for Implementation

Education for Sustainable Development (ESD) plays a key role in achieving the Sustainable Development Goals. However, the implementation of ESD in education remains a challenge, particularly for countries such as Madagascar. ESD needs to consider regional realities to be relevant to learners. An expert study identified health and land-use courses of action for regionally relevant ESD in northeast Malagasy primary education. However, what about teacher perspectives on the possibilities for implementing such courses of action? The present think-aloud study with 10 Malagasy primary teachers used the Integrated Behavioral Model for Water, Sanitation, and Hygiene (IBM-WASH) to analyze factors that teachers perceive to be relevant for implementing health and also—as an innovation—land-use courses of action. The IBM-WASH model is a tool for identifying opportunities and barriers to a desired health behavior. It turned out that the local school’s surroundings, shared values and attitudes, and existing habits are important for implementing health and land-use courses of action. Therefore, regionally adapted health and land-use teaching should consider community-contextual, community-psychosocial, and habitual-psychosocial factors. Additionally, teachers mentioned the costs and benefits of land-use practices. Thus, land-use teaching should take the individual-technological factor into account. This paper argues for a regionally adapted ESD in teacher and school education.

The Genesis of Advertising Communication in the Republic of Belarus: The Ontological Status

The paper presents the research based on the Belarus’s archival materials to trace the genesis of advertising communication starting from the 10th century to present-day Republic of Belarus. The work reveals that the formation and development of advertising communication evolved on the basis of European-wide traditions, but had a number of specific peculiarities. If the technological factor prevails to the forms of advertising communication and ways to reach the target audience, the social political factor has predetermined the content and role of advertising in modern Belarusian society: in the absence of a sovereign state and profound territorial fragmentation, advertising activities in Belarus appeared as a result of the manufacturers’ needs to promote their goods and services. The specifics of advertising communication in the Republic of Belarus are manifested in the slower rate of development progress in comparison to the European level and in the high sensitivity to the political context.

UNDERSTANDING CONSTRUCTION SITE SAFETY HAZARDS THROUGH OPEN DATA: TEXT MINING APPROACH

Construction is an industry well known for its very high rate of injuries and accidents around the world. Even though many researchers are engaged in analysing the risks of this industry using various techniques, construction accidents still require much attention in safety science. According to existing literature, it has been found that hazards related to workers, technology, natural factors, surrounding activities and organisational factors are primary causes of accidents. Yet, there has been limited research aimed to ascertain the extent of these hazards based on the actual reported accidents. Therefore, the study presented in this paper was conducted with the purpose of devising an approach to extract sources of hazards from publicly available injury reports by using Text Mining (TM) and Natural Language Processing (NLP) techniques. This paper presents a methodology to develop a rule-based extraction tool by providing full details of lexicon building, devising extraction rules and the iterative process of testing and validation. In addition, the developed rule-based classifier was compared with, and found to outperform, the existing statistical classifiers such as Support Vector Machine (SVM), Kernel SVM, K-nearest neighbours, Naïve Bayesian classifier and Random Forest classifier. The finding using the developed tool identified the worker factor as the highest contributor to construction site accidents followed by technological factor, surrounding activities, organisational factor, and natural factor (1%). The developed tool could be used to quickly extract the sources of hazards by converting largely available unstructured digital accident data to structured attributes allowing better data-driven safety management.

Customers’ Perceived Risk and Attitude towards Adoption of the Digital Banking Services

Extensive use of technology in the banking sector has redefined the role of a modern banker and banks are not mere purveyors of credit but providers of a number of hi-tech services at the doorsteps of customers anytime, anywhere, and anyhow. The banking industry is currently witnessing healthy competition to adopt new technology. With the advent of Information Technology and its massive application in banking, the delivery of banking services has become more electronic and online. The demand for internet banking (IB) is necessitated by the growing e-commerce transactions and the paradigm shift in banking led by technology. From the perspective of both users and providers‘, IB is cost-effective, quick, and convenient. IB as a medium of delivering banking services is gaining acceptance from customers and is fast catching up in India particularly in Kerala with almost all the banks offering IB services to their customers. Customers are realizing the comfort of accessing banking services from home and as a result, a number of bank customers have already adopted IB or are on the threshold of adopting it. At the same time, we cannot ignore the various kinds of risks hidden in the IB services. Not only the technological factor but also the social, demographic, and even geographical factors also influence us for being digital. As a result of the currency demonetization from 8th November 2016, the demand for digital banking services has been increased. This is mainly because of the unexpected financial crisis that emerged due to currency demonetization. So it led to a new digital revolution in the field of the banking industry. Comparing to conventional banking services digital banking will provide a different experience to its customers. As a result of currency demonetization, many of the consumers were forced to adopt digital banking services. Hence this descriptive study is trying to reveal the great risk perceived by the banking customers in the banking services and the wild adoption of digital banking as a result of currency demonetization by taking samples from state bank of India and Kerala Gramin bank customers. This study sheds light on different aspects of consumers’ perceived risk to analyze the influence of total perceived risk and consumers’ willingness to embrace innovation on digital banking services adoption.

Exploring the Elements Influencing the Behavioral Adoption of E-Commerce by Chinese Small and Medium Enterprises (SMEs)

This study investigated the behavioral adoption of electronic commerce (EC) among small and medium enterprises (SMEs) in China. This was undertaken by integrating the Technological, Organizational, and Environmental (TOE) framework into the Unified Theory of Acceptance and Use of Technology (UTAUT). The data generated from 349 SMEs were analyzed with SPSS and SmartPLs 3.0 via the utilization of the structural equation modeling (SEM) procedure. The results reveal that while the environmental factor was a positive predictor of the performance expectancy of EC among SMEs, it does not, however, encourage the adoption of EC. Again, while the knowledge factor was not significant in driving the performance expectancy of EC, it was a significant determinant of the adoption of EC among SMEs. Also, the study found that organizational factor was a positive predictor of both performance expectancy and the adoption of EC by SMEs. The technological factor was not a significant predictor of the intention to use EC but was significant in determining the performance expectancy of EC. Finally, the study demonstrated that the performance expectancy of EC was a significant predictor of the behavioral adoption of EC. The managerial and research implications of these findings are deliberated.

Technology as an influential variable in the development of dialogical learning

Schools have a responsibility to prepare new generations born in a globalized and interconnected world. The main objective of this paper is to analyze the role that technology plays in the development of dialogical learning in learning communities. We try to understand the influence that technology has in fostering communication and interaction in an educational project that presents interaction and words as basic learning tools. An instrumental, interpretive, and embedded case study is applied in which the communicative methodology is developed from interviews and two discussion groups. The singular case involves a rural school constituted as a learning community that is geographically split into two villages; each village has its own lecture room, one with technology immersion (A) and another with progressive incorporation of technology (B). The results show the influence of the technological factor in learning development that facilitates the creation of meaning; a pedagogical principle that learning communities develop to promote dialogical learning.

Investigation of the Causes of Violations of the Radioactive Balance between Radionuclides of the Uranium Decay Chain

Throughout the literature, it is mentioned that 15 radionuclides in the uranium decay chain have a constant radioactive equilibrium. Theoretical calculations give the value of the activity of each radionuclide in the uranium decay chain.This article examines various factors that affect the coefficient of radioactive equilibrium between radionuclides in the uranium decay chainThe concept of the coefficient of violations of nuclear equilibrium between radionuclides is adopted to determine the degree of violations in the uranium decay chain.Many nuclear-physical factors influence the radioactive balance between radionuclides. The most important of them is the recoil energy that the daughter nucleus receives when splitting from the mother nucleus.Another critical factor in the violation of the radioactive balance between radionuclides is the technological factor: leaching (acid, mini-reagent, bicarbonate, etc.) when leaching uranium by underground leaching of uranium.In addition, as a theoretical result of the study, the article presents a graphical relationship between the number of nuclear masses and the recoil energy of radionuclides in the uranium decay chain.
