Cawley, Peter. "Structural health monitoring: Closing the gap between research and industrial deployment." Structural Health Monitoring 17, no. 5 (January 29, 2018): 1225–44. http://dx.doi.org/10.1177/1475921717750047.
Full textAbstract:
There has been a large volume of research on structural health monitoring since the 1970s but this research effort has yielded relatively few routine industrial applications. Structural health monitoring can include applications on very different structures with very different requirements; this article splits the subject into four broad categories: rotating machine condition monitoring, global monitoring of large structures (structural identification), large area monitoring where the area covered is part of a larger structure, and local monitoring. The capabilities and potential applications of techniques in each category are discussed. Condition monitoring of rotating machine components is very different to the other categories since it is not strictly concerned with structural health. However, it is often linked with structural health monitoring and is a relatively mature field with many routine applications, so useful lessons can be read across to mainstream structural health monitoring where there are many fewer industrial applications. Reasons for the slow transfer from research to practical application of structural health monitoring include lack of attention to the business case for monitoring, insufficient attention to how the large data flows will be handled and the lack of performance validation on real structures in industrial environments. These issues are discussed and ways forward proposed; it is concluded that given better focused research and development considering the key factors identified here, structural health monitoring has the potential to follow the path of rotating machine condition monitoring and become a widely deployed technology.

"Devising an individually oriented method for selection of scientific activity subjects for implementing scientific projects based on scientometric analysis." Eastern-European Journal of Enterprise Technologies 6, no. 3 (114) (December 29, 2021): 93–100. http://dx.doi.org/10.15587/1729-4061.2021.248040.
Full textAbstract:
The main factors influencing the choice of individual subjects of the scientific activity or potential partners and executors for scientific and educational projects were analyzed. The specific features of choosing project executors of different categories were indicated. The functional responsibilities of project participants in accordance with the project structure were described. The individually oriented method for choosing subjects of scientific activity as executors of scientific and educational projects was developed, taking into account the productivity of their scientific activities in the past and considering the structure of projects. To determine the merits of the subjects of scientific activity, which are included in the relevant scientific subject spaces, it is necessary to apply the procedure of their productivity assessment. In addition, it is necessary to predict a change in productivity in the future based on retrospective data for this subject. Next, it is required to solve the multi-criteria problem of the choice among the subjects of scientific activity who are quite productive in the opinion of the project manager. The use of the developed method reduces the subjective impact on making a decision regarding the choice of project executors. This is due to the fact that they are chosen by automated calculation of scientometric indicators of subjects, guided only by open sources of information. The individually oriented method for the selection of subjects of scientific activity was verified on the example of the formation of three applications of research projects. As a result, the average percentage of scientists who meet the requirements of project managers for each scientific subject space was about 46.55 %. The percentage of those involved in the project from those who were selected is about 24.07 %. The probability of cooperation is higher among those who have an average H-index.

Full textAbstract:
The mechanical properties of materials deteriorate when hydrogen embrittlement (HE) occurs, seriously threatening the reliability and durability of the hydrogen system. Therefore, it is important to summarize the status and development trends of research on HE. This study reviewed 6676 publications concerned with HE from 1997 to 2022 based on the Web of Science Core Collection. VOSviewer was used to conduct the bibliometric analysis and produce visualizations of the publications. The results showed that the number of publications on HE increased after 2007, especially between 2017 and 2019. Japan was the country with the highest numbers of productive authors and citations of publications, and the total number of citations of Japanese publications was 24,589. Kyushu University was the most influential university, and the total number of citations of Kyushu University publications was 7999. Akiyama was the most prolific and influential author, publishing 88 publications with a total of 2565 citations. The USA, South Korea and some European countries are also leading in HE research; these countries have published more than 200 publications. It was also found that the HE publications generally covered five topics: “Hydrogen embrittlement in different materials”, “Effect of hydrogen on mechanical properties of materials”, “Effect of alloying elements or microstructure on hydrogen embrittlement”, “Hydrogen transport”, and “Characteristics and mechanisms of hydrogen related failures”. Research hotspots included “Fracture failure behavior and analysis”, “Microstructure”, “Hydrogen diffusion and transport”, “Mechanical properties”, “Hydrogen resistance”, and so on. These covered the basic methods and purposes of HE research. Finally, the distribution of the main subject categories of the publications was determined, and these categories covered various topics and disciplines. This study establishes valuable reference information for the application and development of HE research and provides a convenient resource to help researchers and scholars understand the development trends and research directions in this field.

Full textAbstract:
The article is devoted to the problems of determining the ways of training highly qualified specialists in the field of vocational education. The problem is evidenced by the constant decrease in the order of the Ministry of Education and Science for specialists in the garment industry, services and even computer technology. The situation is similar in the field of mechanical engineering, materials processing, electronics. Natural sciences are in almost no demand, there is no effective actualization of the need for natural and mathematical training. However, global scientific and technological progress requires the accelerated development of these industries, which creates a contradiction in the state between social demand and reality. The laws of Ukraine, the resolutions of the Cabinet of Ministers, the orders of the Ministry of Education and Science on education indicate that they clearly highlight the long-term aspects of education development, including global: the idea of digital transformation and STEM education. In our opinion, the selected areas deserve attention. In this regard, we have outlined the structure of the study of the educational state of society, on the basis of which it is advisable to conduct research to eliminate the contradictions that occur. In a holistic system, the trajectory of further development should be outlined: - according to the horizontal rhythm of system changes (cyclicity, recurrence); - vertical, which ensures the development of the system, ie the next turn of the spiral is higher than the previous one. Given the holistic system of the structure of progress of the educational society, the trajectories of development form the concept of a methodological approach to the concept of sustainable development on the basis of digitalization and stemization. The whole educational system must be permeated with fundamental didactic categories and principles that serve as links between the elements of the system. Practice shows that studying pedagogy, methods of teaching a subject for a student mostly ends with a final certification. In this regard, the educational system must be permeated with fundamental didactic categories and principles that serve as links between the elements of the system. Practice shows that studying pedagogy, methods of teaching a subject for a student mostly ends with a final certification, and at school it all mostly goes into the background. Therefore, the article considers the basic patterns of formation of lesson theory.

Full textAbstract:
Non-adherence to public health measures determines how society copes with the new coronavirus pandemic. In this study, we apply the personal construct theory to answer why some people comply with anti-epidemic measures. The theory assumes that stressful events in the pandemic situation invalidate an individual’s worldview (individual’s construing). If the individual attempts to maintain this construing instead of its reconstruction, s/he may apply the hostility strategy. For example, s/he dismisses information or opinions that are incompatible with his/her original construing. This leads to an elaboration of distrust and critical attitudes towards institutions and to non-compliance with measures they order. We investigate this model by an interview analysis with 20 respondents. The analysis yielded five categories showing how respondents construe the pandemic situation: responsibility, criticism, distance from the subject, productive dialogue, and unproductive dialogue. Respondents from the category “criticism” were facing substantial stressful/invalidating changes. They maintained their critical attitude towards anti-epidemic measures through a hostile view of those with differing opinions and a strong distrust in institutions and media. The other respondents mostly complied with the measures. In their construing of the pandemic situation, they took different perspectives into the account, did not experience hostility, and expressed some degree of understanding to people with different opinions. Thus, hostility could be a fundamental psychological principle to preserve a meaningful worldview in times of the pandemic. Hostility, however, leads to distrust, opinion polarization, and non-compliance with anti-epidemic measures.

Full textAbstract:
The author examines the definitions used in legislative documents and pedagogical research connected with the activity of subjects – participants of the educational process («scientific and pedagogical activity», «scientific activity», «pedagogical activity», «creative pedagogical activity», «professional pedagogical activity»). It is stated that the generic concept of the term «scientific and pedagogical activity» («scientific activity», «pedagogical activity») is defined depending on who is the subject of such an activity (a scientist or an educator). The conclusion is drawn that such categories as «scientific activity» and «pedagogical activity» are not identical. The domestic experience related to the interpretation of the concept «pedagogical activity» was analysed. The researchers considered it to be a special kind of social activity, a kind of socially useful activity implemented by adults, teachers’ activity in the course of educational process, a creative process of conscious, purposeful, self-regulated activity of the teacher. It is stressed that the methodological subsystem is indirectly present in such subsystems of teachers’ creative pedagogical activity as didactic, educational, organizational and administrative, social-pedagogical and self-improvement ones. The levels of teachers’ creative pedagogical activities (reproductive, labour-saving, design, innovative ones) were specified. The article is focused on the content of the concept «function of the professional activities of academic staff», which is treated as an invariant component of productive activity of academic staff, the effectiveness of which is provided by applied educational tools, taking into account modern tendencies and developmental peculiarities of education institutions, as well as the level of their professional ability. The main types of teachers’ professional and pedagogical activities are determined (diagnostics of professional orientation, ability to learn, teach and educate; design activity; learner-centred professional training; social and professional education; extracurricular educational work; raising the level of professional and pedagogical education and qualification; innovative activity). The organizational and pedagogical conditions for structuring scientific and pedagogical activities of academic staff in higher education institutions were generalized (ensuring structural and functional unity; staff and structural units’ optimization; standardization of information links; ensuring multifaceted development of academic staff and their self-organization; compliance with the principles of systematicity and complexity in the implementation of professional and job functions). The functions of professional activity of academic staff were distinguished (administrative, motivational, developmental, prognostic, corrective, culturological, educational, professional, the function of providing educational services).

With the Railway Age, the perception of the landscape has changed. In Austria, the world’s first high mountain railway was built in the middle of the 19th century. It crosses the Alps at one of their eastern foothills, the Semmering. The central subject of this study is the landscape that was completely transformed by the construction of the Semmering Railway between 1852 and 1873. How was the Semmering perceived before it was discovered by the Viennese society as a region of summer resort? How were the massive changes in the Alpine landscape caused by the construction of the railway portrayed in the medium of contemporary travel guides?The sources investigated cover the period from the construction of the Semmering Railway to the discovery of the region as a summer resort. Starting with the first travel guides to the construction site and ending with the travel guides to the completed railway, seven main sources were analysed. As a starting point for the qualitative content analysis, a system of categories was developed as a search grid to filter the relevant aspects for answering the research question. The analysis follows the process of coding, paraphrasing and generalizing, and clearly reveals different levels of perception. The landscape in which the railway was built was described in extremely positive, poetic formulations. The negatively judging descriptions are particularly remarkable in the context of the travel guides, as they can be read as a critical reflection of the changed situation. Instead of regretting the destruction of nature, the victory of man or technology over nature was celebrated. From the comparison of the travel guides to the construction site and those to the completed railway, the progress of the construction work is clearly readable. The magnificence of the construction project was beyond question from the very beginning. The travel guides allow one to comprehend this, at the time rather young, transformation of the landscape; they open up a differentiated view of the landscape.

Full textAbstract:
The paper substantiates that the radical changes taking place in all spheres of modern society necessitate a revision of the basic requirements for the training of specialists who should be not only highly qualified, but also be prepared for lifelong education. It has been shown that the state regulations and international documents on education define lifelong learning as the main vector of educational development in the 21st century. It has been determined that the achievement of this goal is possible due to the organization of the training process at university, aimed at gradual transition from the traditional educational format in the form of providing students with a set of ready-made knowledge to self-education, which is the highest degree of education. The essence of the key components of the concept “self-education”, i.e. the categories “self-“ and “education” has been disclosed. The essential differences between the concepts “training” and “education” have been explained, namely: the purpose of training is forming utilitarian skills with specific pragmatic goals, and education is aimed at developing a person as an individual, developing his/her spiritual strengths and abilities. Examples of dictionary equivalents of the term “self-education”, which exist in foreign scientific, reference and encyclopedic literature, have been given. The term “self-education” in the context of philosophy, sociology, psychology and pedagogy has been analyzed. It has been ascertained that among contemporary researchers there is no unanimous position on the interpretation of this term as each of them considers it through the lens of a particular aspect. The main approaches to the definition of the concept “self-education” that have developed in Western pedagogical theory have been characterized. It has been substantiated that full-fledged self-education is possible only if self-study and selfeducation are combined. Self-study involves the acquisition of knowledge on the basis of the person’s own aspirations and through self-selected means. Self-improvement is associated with the manifestation of significant willpower, a high degree of self-awareness, perseverance and purposefulness, resulting in the development of the individual’s qualities that determine the sustainable nature of any kind of independent activity. It has been revealed that in modern didactics self-education is defined as an activity process, and activity is defined as the basis of self-education. The differences between the concepts “self-educational activities”, “independent activity” and “independent work” on key features have been outlined, namely: on the source of goals, the level of independence and the definition of the subject of control over the results. It has been proved that the student’s self-educational activity, in contrast to independent activity, goes beyond external goal-setting and control and is implemented in a completely autonomous mode both during training at university and after graduation. The definition of the term “self-education” is given as the individual’s purposeful systematic cognitive activity, in the course of which he/she independently acquires knowledge and improves skills, resulting in the qualitative development of their personality. The need for continuous self-development is the basis of this activity, and a personal educational product, which involves self-mastery of the system of knowledge and ways to acquire it as well as the development of personality and his/her abilities, is the result of this activity. The main characteristics of self-educational activity are motivational activity, internal freedom, purposefulness, ability to independently acquire necessary knowledge, a strong desire for self-improvement.

Full textAbstract:
The issue of the relationships between anxiety and aggressiveness among Ukrainian women in war conditions has been dealt with in this article. The relevance of the chosen topic is beyond doubt, since social problems based on psychological factors are especially relevant during the war. It is substantiated that a change in the usual living conditions leads to a significant increase in anxiety and aggressiveness among women. In this paper, the attention is paid specifically to the study of anxiety and manifestation of aggressiveness by women who are in war conditions. It is worth noting that currently in the psychological and social literature, the number of publications about the problem of anxiety is increasing, since anxiety occupies a special place, as it often leads to a decrease in work capacity, productivity, difficulties in communication, etc. It has been found out that the level of anxiety can be manifested in the aggressive women’s behaviour in the war conditions. It is noted that the state of anxiety and aggressiveness is the most common phenomenon among women in war conditions. The results of the analysis and generalization of scientific sources are presented in this paper. It has been identified that the problem of anxiety and aggressiveness is one of the topical issues of modern psychology. The need for timely identification and work with the anxiety, anxious behaviour and aggressiveness of women in war conditions and after military aggression has been emphasized. The analysis of the questionnaire conducted among Ukrainian women in war conditions has been carried out, and the degree of their influence on women’s daily lives and life activities in war time has been determined. The purpose of this work is theoretical substantiation and empirical study of the specific of the relationships between anxiety and the manifestation of aggressive behaviour of Ukrainian women in war conditions. The object of this study is the anxiety of Ukrainian women in war conditions, whereas the subject of this study is the character of the relationship between anxiety and the manifestation of aggressiveness of Ukrainian women in war conditions. The conceptual hypothesis of this research lies in the assumption of the presence of significant relationship between anxiety and the manifestation of aggressiveness of Ukrainian women in war conditions, and it has been fully confirmed. Considering the influence of war conditions on the anxiety and aggressiveness of Ukrainian women, the relationship between the mentioned psychological categories has been claimed. It has been revealed that the state of anxiety can be manifested in the aggressive behaviour of women in war conditions. It is noted that the state of anxiety and aggressiveness is the most common phenomenon among women in war conditions. According to the results of this study, there have been identified those significant relationships between indicators of anxiety and certain forms of aggressiveness among Ukrainian women in war conditions. It is substantiated that the high level of manifestation of anxiety is caused by certain psychological features. It has been found out that the increase in the level of anxiety, indicators of family anxiety and anxious behaviour is associated with an increase in the level of aggressiveness of Ukrainian women. The practical significance lies in the fact that the obtained results can be used by employees of psychological services, practical psychologists during counselling at various stages of psychotherapeutic work with women in war conditions.

AbstractThe importance of learning style in student’s learning performance has been gaining scholar’s attention since it was coined in the early 70s. Atmatzidou’s robotics procedure of a five-stages robotic activities was deployed in the research. This study adopts a case study research design for gathering and analyzing data as the case research allows the exploration of unforeseen phenomena and offers insights into the interdependencies among components revealed in the study. This research introduces the use of Lego Mindstorm as the mean of pro-filing a student’s behavioral patterns. Student’s behavior patterns, then, mapped into radar charts to present the extent of both Kolb and science, technology, engineering, and math (STEM)’s profile of student’s learning style categories. The paper contributes to theory by extending Kolb’s Learning Style instrument by mapping the pattern of learning styles identified in the research and exploring students learning experience. Dominant four-domain-indicators captured during the activities characterize Students’ learning profiles. While the Kolb Learning Style and its instrument are considered classic in hands-on literature, the use of educational robotics to elaborate students’ learning style is novel in the literature that may affect the delivery of non-technology subjects in the curricula.

This study explores a bibliometric approach to quantitatively assessing current research trends on sludge, by using the related literature published between 2000 and 2011. The articles acquired from such literature were concentrated on the general analysis by publication type and language, characteristics of articles outputs, country, subject categories and the frequency of title-words used. Over the past 12 years, there had been a notable growth trend in publication outputs, along with more participation of countries/territories. An analysis of the title-words showed that wastewater treatment was still the most hot topic in sludge research and wastewater, heavy metal, waste water treatment and anaerobic digestion were recent major topics of sludge research. Besides, membrane bioreactor technology has been advancing rapidly around the world and became an ideal way to reduce sludge production in the wastewater treatment process.

This paper aims to evaluate the knowledge landscape of the phytoremediation of heavy metals (HMs) by constructing a series of scientific maps and exploring the research hotspots and trends of this field. This study presents a review of 6873 documents published about phytoremediation of HMs in the international context from the Web of Science Core Collection (WoSCC) (1989–2018). Two different processing software applications were used, CiteSpace and Bibliometrix. This research field is characterized by high interdisciplinarity and a rapid increase in the subject categories of engineering applications. The basic supporting categories mainly included “Environmental Sciences & Ecology”, “Plant Sciences”, and “Agriculture”. In addition, there has been a trend in recent years to focus on categories such as “Engineering, Multidisciplinary”, “Engineering, Chemical”, and “Green & Sustainable Science & Technology”. “Soil”, “hyperaccumulator”, “enrichment mechanism/process”, and “enhance technology” were found to be the main research hotspots. “Wastewater”, “field crops”, “genetically engineered microbes/plants”, and “agromining” may be the main research trends. Bibliometric and scientometric analysis are useful methods to qualitatively and quantitatively measure research hotspots and trends in phytoremediation of HM, and can be widely used to help new researchers to review the available research in a certain research field.

This article reviews application of science and technology in predicting and control of disasters. Science and technology can also help to control the severity of a disaster, but here the achievements to date are much less spectacular than those in the prediction arena. The prediction of weather-related disasters has had spectacular successes within the last few decades. For disasters that involve fluid transport phenomena, such as severe weather, fire, or release of a toxic substance, the governing equations can be formulated subject to some assumptions—the fewer, the better. The pains-taking advances made in fluid mechanics in general and turbulence research in particular, together with the exponential growth of computer memory and speed, no doubt contributed immeasurably to those successes.

Full textAbstract:
A public health emergency of international concern, such as a pandemic, disrupts the normal operation of the global supply chain, which necessitates in-depth research on supply chain management. In this paper, we used bibliometric and content analysis to provide a systematic analysis of the supply chain industry from this background. The descriptive analysis provides insights into the publication growth trajectory, in terms of the contributing authors, countries, and subject categories, which presents an intuitive display of previous research. In addition, the existing research mainly covers three dimensions of supply chain disruption, strategies, and sustainability, which can be clustered into supply chain disruption, disruption recovery, reconfiguration, digital intelligence, optimization, and sustainability. By revisiting the supply chain industry, we explored the transformation of its characteristics in the pandemic, covering themes ranging from expansion to contraction, from traditional to digital intelligence, and from fragile to sustainability, which suggests potential research directions for future studies. This contributes to the further research of supply chain management during the pandemic and provides supply chain managers with a practical approach for dealing with supply chain disruption risks and improving supply chain sustainability in this context.

Full textAbstract:
Prefabricated building has become one of the most significant research directions in the architecture, engineering, and construction (AEC) industry and has attracted a large number of scholars and practitioners in recent years. However, few studies have conducted a systematic review on the development of prefabricated building research around the world. In this study, the scientometric method is used to analyze the literature on prefabricated buildings in the past ten years through analysis of co-authors, co-words, and co-citation. From the Web of Science (WOS) core collection database, a total of 1224 articles were collected for statistics and analysis. The analysis results indicated that Bruno Dal Lago obtained the maximum number of co-citations, and the most significant country/region and research institution in prefabricated building research were China and Tongji University, respectively. It was also found that engineering, civil engineering, and construction and building technology were the top three subject categories that prefabricated building research belonged to. Among all the keywords of the collected articles, citation bursts were received by “cladding panel,” “precast concrete,” and “project.” Moreover, there were 11 co-citation clusters identified from the articles, and their themes included precast structures, waste management, progressive collapse, delay, precast facades, carbon reduction, laser scanning, and prefabricated residential building. This paper is expected to provide researchers and practitioners in this field a detailed and in-depth understanding of the trend and status of global research on prefabricated buildings.

Abstract: The purpose of this study is to understand the importance of personal finance planning to be financially sound and well equipped for the uncertainty. According to the findings of this study, the ignorance of personal finance is to the pinnacle. This isn't just to set up family spending plan yet additionally to save, contribute as well as plan for our retirement. The meaning of financial management, its significance, the steps that each person can take to plan and manage their finances, and the awareness of financial management are all discussed in this writing. In addition to educating readers on how to plan and manage each individual's finances for their benefit today and in the future, which indirectly contributes to the development of the nation, the purpose of this writing is to raise awareness of the significance of personal finance planning and management. The impact of personal finance education on financial knowledge, attitudes, and actions is the subject of much debate. Our research also reveals that discussing money with friends, income, work experience, year/field of study, and family financial socialization were all important factors in influencing financial knowledge, attitudes, and behavior. We're not saying that formal financial education isn't important; rather, we're saying that its role in changing people's attitudes and behaviors should be carefully considered if that's its goal. The objective was to describe the financial knowledge, attitudes, and experiences of residents to inform the design of a personal finance curriculum.

This study aimed to analyze the perception of patients and the prevalence of systemic and oral risk factors in patients with coronary artery disease (CAD). This is a quali-quantitative study in which 56 patients with CAD had quantitative and qualitative data collected and analyzed. Of the 56 patients who made up the sample, 41 had their oral cavity examined and 11 were interviewed. Of this total, 46.42% have no education; 64.28% are unemployed; 72.41% have low family income; 25% are smokers; 17.85 are obese; 76.78% have hypertension; 30.36% diabetes; and 64.29% admitted having inadequate eating habits. In the qualitative analysis, 4 (four) categories emerged from the interviews and it was possible to identify, in general, the lack of knowledge of risk factors regardless of education level. In general, it was observed that, in this study, the social and demographic conditions and morbidity rates of the studied population were worse than the average of data from regional and national registries. The perception of risk factors as a cause of CAD was low and regardless of education level. The population studied showed a higher prevalence of risk factors when compared to regional and national averages. These facts may have increased the subjects' vulnerability and contributed to the development of CAD.

Full textAbstract:
The article deals with the problematization of the study of the kon (unwritten rules) phenomenon. The functions of the unwritten rules (kon) are compared with the functions of the law. The constitution of social reality as a socio-historical process that establishes the basic categories of society's perception of its social existence is the object of research. The subject of the study is the poorly studied functions of the “kon” in the constitution of social reality. The methodology is held together by general theoretical methods of typology and comparison. The study is built from the observation of the historical phenomenon of the horse to the disclosure of the heuristic potential of the concept of “kon” for describing the phenomena of modern life. The basis of the methodology is the theory of binary oppositions of culture by A.S. Akhiezer, reinforced the dialectical-dialogical pragmatic model of metacommunication R.T. Craig. The social functions of the horse remain poorly studied due to a certain way of configured research optics, concentrated on the laws governing the control of a single center of power by a poorly organized periphery.

AbstractInterest in hydrogen-powered rail vehicles has gradually increased worldwide over recent decades due to the global pressure on reduction in greenhouse gas emissions, technology availability, and multiple options of power supply. In the past, research and development have been primarily focusing on light rail and regional trains, but the interest in hydrogen-powered freight and heavy haul trains is also growing. The review shows that some technical feasibility has been demonstrated from the research and experiments on proof-of-concept designs. Several rail vehicles powered by hydrogen either are currently operating or are the subject of experimental programmes. The paper identifies that fuel cell technology is well developed and has obvious application in providing electrical traction power, while hydrogen combustion in traditional IC engines and gas turbines is not yet well developed. The need for on-board energy storage is discussed along with the benefits of energy management and control systems.

Full textAbstract:
The article presents literary, sociological and cultural points of view on the problem of the literary canon, describes the mechanisms of canonization and defines the boundaries of the Russian classics. The author discovers a connection between the texts claiming the status of the canonical hierarchy and the question of ethnicity. The article establishes that the construction of both a national self-portrait and the image of a foreigner (the Other) are the most important functions of the classical canon. The object of this research is a unified discursive field of Russian classical literature. The subject is the generalized image of the German that forms in this field. The author, resorting references to current research practices of discourse analysis, establishes that the portrait of a German is based on such conceptual categories as: 1) the connection with the soil and nature, 2) the connection with roots, 3) reliance on reality and "mundanity", 4) planning, 5) positivism and subordination, 6) perception of life as a mechanism. The construction of the Other creates an opposition to the "Russian" in the structure of the classical text and builds a series of binary pairs: heredity / freedom, stability on the ground / ability to jump, clear planning / dreaminess, legalism / Paschality, self-aggrandizement / self-abasement, godlessness / Orthodoxy. The article reveals that the German hero acts as a constituent of the Other, provoking self-determination and self-identification.

Hydrogen is a notoriously difficult substance to store yet has endless energy applications. Thus, the study of long-term hydrogen storage, and high-pressure bulk hydrogen storage have been the subject of much research in the last several years. To create a research path forward, it is important to know what research has already been done, and what is already known about hydrogen storage. In this review, several approaches to hydrogen storage are addressed, including high-pressure storage, cryogenic liquid hydrogen storage, and metal hydride absorption. Challenges and advantages are offered based on reported research findings. Since the project looks closely at advanced manufacturing, techniques for the same are outlined as well. There are seven main categories into which most rapid prototyping styles fall. Each is briefly explained and illustrated as well as some generally accepted advantages and drawbacks to each style. An overview of hydrogen adsorption on metal hydrides, carbon fibers, and carbon nanotubes are presented. The hydrogen storage capacities of these materials are discussed as well as the differing conditions in which the adsorption was performed under. Concepts regarding storage shape and materials accompanied by smaller-scale advanced manufacturing options for hydrogen storage are also presented.

Full textAbstract:
The development of Industry 4.0 (I4.0) and the digitization and automation of manufacturing processes have created a demand for designing smart warehouses to support manufacturing processes. Warehousing is one of the fundamental processes in the supply chain, and is responsible for handling inventory. Efficient execution of warehouse operations often determines the effectiveness of realized goods flows. Therefore, digitization and its use in exchanging information between partners, especially real-time inventory levels, is critical. For this reason, the digital solutions of Industry 4.0 have quickly found application in internal logistics processes and enabled the design of smart warehouses, also known as Warehouse 4.0. The purpose of this article is to present the results of the conducted review of publications on the design and operation of warehouses using the concepts of Industry 4.0. A total of 249 documents from the last 5 years were accepted for analysis. Publications were searched for in the Web of Science database using the PRISMA method. The article presents in detail the research methodology and the results of the biometric analysis. Based on the results, a two-level classification framework was proposed, which includes 10 primary categories and 24 subcategories. Each of the distinguished categories was characterized based on the analyzed publications. It should be noted that in most of these studies, the authors’ attention primarily focused on the implementation of (1) Industry 4.0 technological solutions, such as IoT, augmented reality, RFID, visual technology, and other emerging technologies; and (2) autonomous and automated vehicles in warehouse operations processes. Critical analysis of the literature also allowed us to identify the current research gaps, which will be the subject of further research by the authors.

Full textAbstract:
Hot stamping technology has shown a significant scientific yield in the last decade. The research activity in that field has spread across several disciplines such as materials science, mechanics, process engineering, instrumentation, physics, or part-tool design engineering. Some recent publications have gathered this richness in the format of scientific reviews. This work is aimed to draw a picture of this scientific production in bibliometric terms, which are complementary to the existing reviews. The literature is, in this case, approached from different angles: geographical, collaborative, disseminative, and keyword-based. The first one leads to mapping the share of each region worldwide in advance of the hot stamping technology in terms of scientific production volume. The second angle allows identifying the most productive networks that have been established between institutions and the most influential agents in the field. The third one ranks the most influential journals and events based on citation rates, which indicates where to publish in order to achieve the highest impact. Finally, the fourth approach targets to infer research trends from assessing the keywords employed in the published scientific literature. Altogether, the results show a scenario with Asia as the major player both in volume and networking success, CHS2 as the most relevant event, and exploring alternatives to the conventional AlSi coated 22MnB5 hot stamping as a subject rising of interest.

Full textAbstract:
The subject of research is a phenomenon of prosumption, i.e., the intertwining of consumption and production processes, until the differences between them are blurred. When consumers produce goods and services for their use, they become prosumers. The article aimed to assess consumer behavior in terms of various forms of prosumer activity on the market of household-related services. The types of prosumer activity of rural households and their size were determined during the analyses. The article uses primary sources from a survey conducted among residents of rural areas of the Masovian Voivodeship in Poland in 2017. Statistical, descriptive, and comparative methods were used. The research shows that consumers are very active in the field of prosumption, rationally running their households. The study used principal component analysis (PCA) and selected descriptive statistics. The research results showed that the services performed can be grouped into three categories, i.e., the index of basic living self-sufficiency of households, the index of renovation and repair self-sufficiency, and the index of professional self-sufficiency of farms. Consumers usually prepare meals at home and clean, iron, and wash clothes, thus reducing the costs of running a household. It is also popular to carry out repairs oneself or to carry out repairs of equipment at home.
