Large-scale disruptive activism strengthened environmental attitudes in the United Kingdom
Authors: Kenward Ben , Brick Cameron
Published: January 2023

The 2019 London Extinction Rebellion was the first attempt by environmental protesters to create prolonged large-scale disruption in a Western capital city. The effects on public opinion were difficult to predict because protests seen as extreme can reduce support, but protests seen as justified can increase support. We studied longitudinal opinion changes in a nationally representative sample (n = 832) before, during, and after the rebellion, in conjunction with experimental analysis of the causal effects of media reports (n = 1441). The rebellion was longitudinally associated with national increases in environmental concern, and activist media increased dissatisfaction with current government action. Reports from an activist, the BBC, and the Daily Mail caused activism intentions and support to move in different directions, contributing to longitudinally increased polarisation in attitudes to activism. The rebellion had minimal effects on belief in whether ordinary people can produce relevant change (based on collective efficacy and support for a Citizens’ Assembly). The rebellion thus succeeded in some aims and did not show evidence of any important backlash.

Relationship of odontometric and cephalometric indicators. Review of literary sources
Authors: Ryabov T. V.
Published: January 2023

Annotation. The construction of a correct orthodontic intervention that will satisfy the aesthetic and functional needs of the patient requires the perception of the craniofacial region as a single complex. At the same time, it is necessary to understand the relationship of each component of this complex and its influence on each other in order to better predict the expected result of treatment and its planning. The purpose of this study is to review modern scientific sources devoted to the study of the relationship between odontometric and cephalometric indicators. For this, a search for literary sources related to the research topic in the period 2012-2022 was performed on the basis of Google Scholar using keywords and inclusion/exclusion criteria, in particular, the presence of previous review of articles, the representativeness of the sample, and the presence of statistical analysis of the obtained data. The analysis of selected literary sources showed that the vast majority of publications are devoted to the topic of studying the relationship of odontometric and cephalometric indicators under the conditions of pathology of the dental and jaw system. Also, in most sources, researchers do not prefer the use of one or two methods of cephalometric analysis of lateral teleroentgenograms, but use complex analysis methods. At the same time, scientists pay attention to its ethnicity, gender and age when drawing up a sample. Thus, taking into account the relevance of this research topic and at the same time the lack of studies aimed at determining the relationship of cephalometric and odontometric indicators under the conditions of orthognathic bite, there is a need to conduct this kind of clinical experimental study on the Ukrainian population using several of the most common methods of cephalometric analysis.

Authors: Park Sehan , Lee Dong-Ho , Lee Choon Sung , Hwang Chang-Ju , Yang Jae Jun , Cho Jae Hwan
Published: January 2023

Occasionally, ossification of the posterior longitudinal ligament (OPLL) causes cord compression, resulting in cervical myelopathy. OPLL differs from other causes of cervical spondylotic myelopathy in several ways, and the surgical strategy should be chosen with OPLL’s characteristics in mind. Although both the anterior and posterior approaches are effective surgical methods for the treatment of OPLL cervical myelopathy, they each have their own set of benefits and drawbacks. Anterior decompression and fusion (ADF) may improve neurological recovery, restore lordosis, and prevent OPLL mass progression. The benefits can be seen in patients with a high canal occupying ratio or kyphotic alignment. We discussed the benefits, limitations, indications, and surgical techniques of ADF for the treatment of OPLL-induced cervical myelopathy in this narrative.

The application of the analytical method ‒ the method of direct integration ‒ to calculations of building structures in the form of circular plates and plates on a continuous variable elastic base is considered. It is noted that there are no proposals for a general analytical method for calculation of annular plates on a variable elastic base in the literature. And the need for such a method is obvious, since it makes it possible to estimate the accuracy of finite element analysis. A detailed description of the algorithm of the direct integration method is not given in the paper, and all the calculation formulas for the circular plate are taken from the authors’ already published article. The results of numerical implementation of this algorithm for specific examples are considered. In order to verify the results of calculations by the author’s method, computer modeling of the considered circular plates in PC LIRA-SAPR and their calculations by the finite element method have been performed. The reaction of the foundation is described by the Winkler model with a variable bedding factor. The calculation of a concrete slab that is rigidly pinched on the inner contour and articulated on the outer contour is performed. And calculation of a steel plate with rigid pinching on the outer contour and articulated on the inner contour. In the first case, the bedding factor is assumed constant, and in the second case, it changes according to the linear law. The calculations showed that the discrepancy between deflections calculated by the finite-element method and the author’s method does not exceed 1%, and the results of radial and circumferential moments calculation differ more considerably, amounting to 10%. The authors explain this difference by the inaccuracy of the numerical analysis associated with a semi-automatic method of constructing a finite-element mesh, which should be made finer. The densification of the mesh in the manual mode of its partitioning significantly reduces the discrepancy between the results of calculating the deflections, radial and circumferential bending moments by the finite-element method and the author’s method.

Published: January 2023

Reinforced concrete became widespread due to its many positive properties: durability, fire re-sistance, resistance to corrosive effects, high resistance to static and dynamic loads, low operating costs for maintaining buildings and structures, and relative cheapness of manufacturing. The presence of widespread large and small aggregate used in the production of reinforced concrete makes it applicable in all corners of the globe and even beyond its borders.The emergence and development of building structures, including reinforced concrete, is inextricably linked to the conditions of the material life of society, the development of productive forces. The appearance of reinforced concrete coincides with the period of accelerated development of industry, transport and trade in the second half of the 19th century. The period of emergence of reinforced concrete (1850-1885) is characterized by the appearance of the first structures made of reinforced concrete in France (Lam-bo, 1850; Quanier, 1854; gardener Monier, 1867-1880), England (Wilkinson, 1854), the USA (Hiatt, 1855-1877). Buildings and structures and their structures during operation experience force and non-force effects of the environment. With a symmetrical effect of the medium, centrally compressed rods remain centrally compressed, and with an extracenteral one, extracentric eccentricity appears. First, the rod experiences off-center compression. Further deformation will lead the rod to longitudinal bending, and under the action of a transverse load to longitudinal-transverse bending. In steel structures, the environment causes corrosion, in concrete ‒ corrosion and neutralization. In a physically linear formulation, these problems are solved, but it is necessary to take into account the real diagrams of steel and concrete, and to solve problems according to an unformed deformed scheme. Given the impact of the environment, new challenges arise with constructive and induced heterogeneity. Noncentrally compressed elements are part of statically definable and indeterminate structures: these are beams, threehinge systems, frames and trusses. This is a new topic, a new formulation of the question, tasks that require the development of new methods.
SOME PROBLEMS OF OPTIMIZATION OF ROD SYSTEMS CONTAINING COMPRESSED ELEMENTS USING ADDITIONAL CONSTRAINTS
Authors:   Odesa State Academy of Civil Engineering and Architecture, Bekshaev S.
Published: January 2023

The article is devoted to the problem of increasing the stability of rod systems containing longitudinally compressed elements. The influence of the imposition of constraints on the behavior of such systems is investigated in order to determine such places for imposing constraints that provide the maximum stability of the system reinforced by the constraint. To get generality, the consideration includes such rod systems that allow various equilibrium configurations, for example, having internal ideal hinges, as well as an arbitrary distribution of longitudinal compressive forces, including leaving some areas free from compression. For the same purpose, the constraints are considered as generalized, producing a reaction with an arbitrary spatial distribution. The paper formulates some general results related to the influence of the introduction of generalized constraints on the critical forces of a rod system with some generalizations related to the extension of the class of rod systems under consideration. Particular attention is paid to the buckling modes in view of their important role as a basis for describing various configurations of the structure. It has been established that the shape of these modes, in particular, the position of their nodes, is essential for finding the optimal position of the constraint. For the case of constraint in the form of a concentrated hinged support, analytical expressions are obtained that represent the derivatives of the critical forces of the system with respect to the coordinate of the support. The case of a multiple critical force, when this derivative, generally speaking, does not exist, is especially considered. These expressions make it possible to qualitatively characterize the optimal position of the support. The application of some of the obtained results is demonstrated by the example of the problem of finding the optimal position of an intermediate hinged support of a two-span rod supported at the ends by elastic hinged supports. These positions are qualitatively described for various values of the stiffness coefficients of the end supports. It has been established that under certain conditions, the optimal positions of the intermediate support correspond to a special semi-curved mode of buckling, in which one of the spans does not bend, but retains its rectilinear equilibrium shape.

In the context of the actual problems of the physics of operational damage of modern reactor steels produced in the leading countries of the world (USA, Russia, Western Europe) and used for the manufacture of nuclear reactor vessels and other equipment of the first circuit of nuclear power plants, the characteristic features of possible dynamic damage in the responsible elements of this are considered. The mentioned problems are systematized from the standpoint of analyzing the effects of radiation embrittlement, as well as physical and chemical processes that, under certain conditions, are capable of developing in the operating equipment of Ukrainian NPPs, which are already working out their design operational resource. The characteristic features of possible dynamic damage in the operating reactor equipment of Ukrainian and foreign nuclear power plants are considered. The problem is systematized, first of all, from the standpoint of analyzing the operational stability of domestic and foreign reactor steels in relation to their radiation embrittlement. The peculiarities of the course of this physical process have been analyzed, which should be taken into account when determining the maximum possible terms of extension of safe operation of nuclear power units with reactors of the VVER type at the NPP of Ukraine. The main metal-physical properties of reactor steels of various types and possible problems caused by neutron irradiation, physical and chemical processes, vibrational and thermomechanical fatigue, which threaten the unexpected sudden destruction of reactor vessels, are considered. Special attention is paid to mechanical damage and processes accompanying the operation of reactor housings under conditions of cyclic and dynamic loads. A warning has been given regarding the unjustified extension of the period of reactors safe operation. The significant technological lag of the former Soviet, and now Russian, metallurgy from the level of metallurgy of the leading Western countries was noted. Data are provided on the high operational properties of the latest American steels, from which modern reactors of the AR1000 type are manufactured in the USA, and the safety, technical, economic and environmental advantages of using these reactors in Ukraine in comparison with new models of reactors of the VVER-1000 and VVER-1200.

This research aims to examine and analyse some of the problems that women in leadership positions face in South African higher education. Women have been denied leadership positions in higher education. This became increasingly clear in developing countries such asSouth Africa. However, in recent years, there has been a great increase in the achievement of women in leadership roles in higher education.. South African higher education has undergone a gender stereotype reversal, largely due to an increase in women in leadership positionssuch as vice-chancellors, rectors, deans, and department heads. This study contends that being a female does not preclude successful leadership in South African higher education. A qualitative content analysis was utilised to guide this work when reviewing and analysing current scholarly literature such as articles, book chapters, and theses. To build a coding system and present the findings of this paper, the following themes were identified:(1) challenges women face in leadership positions in South African higher education; (2) the influence of patriarchy in leadership positions in higher education; (3) Influence of patriarchy in leadership positions in higher education; (4) Redressing the challenges faced by women in higher education. The findings of this paper revealed that being a woman is not a barrier to success in leadership, but they also highlighted that women continue to face basic problems in academic leadership. This article concludes by claiming that gender stereotypes, gender inequity, and discrimination against women in leadership roles are issues preventing women from achieving their career progression goals in academia.

Published: January 2023

Human-computer interaction (HCI) technology plays a critically essential role in the computer-aided design of railway line locations. However, the traditional interactive design with a mouse+keyboard cannot well meet the rapid generation requirements of the railway line during scheme discussion. This research presents a fitting algorithm for the rapid generation of railway lines by using a multi-touch gesture algorithm. The fitting method from free hand-drawing lines to satisfied railway lines is proposed. Then the interactive operation hand gestures are defined and implemented into the railway line location design. The hand-drawing lines generated by defined gestures are automatically fitted with the target horizontal line by using the inflection detection algorithm based on Euclidean Distance (ED). Meanwhile, the vertical line can be fitted by a similar algorithm with an extreme point-to-point (EPP) and chord-to-point distance accumulation (CPDA). Moreover, a real-world example verification is carried out. The multi-touch gesture algorithm is applied for the automatic fitting of the railway line. Compared with the traditional interactive methods, the consumption time of railway line generation by using the multi-touch interactive mode is decreased by about 15%. This research provides fundamental support for rapid scheme discussion of railway line generation based on natural HCI, which is well-matched with modern handheld devices, and the requirements of rapid selection as well as the quick comparison of railway line schemes in the early stage of design.

Published: January 2023

Healthcare informatics is one of the major concern domains in the processing of medical imaging for the diagnosis and treatment of brain tumours all over the world. Timely diagnosis of abnormal structures in brain tumours helps the clinical applications, medicines, doctors etc. in processing and analysing the medical imaging. The multi-class image classification of brain tumours faces challenges such as the scaling of large dataset, training of image datasets, efficiency, accuracy etc. EfficientNetB3 neural network scales the images in three dimensions resulting in improved accuracy. The novel neural network framework utilizes the optimization of an ensembled architecture of EfficientNetB3 with U-Net for MRI images which applies a semantic segmentation model for pre-trained backbone networks. The proposed neural model operates on a substantial network which will adapt the robustness by capturing the extraction of features in the U-Net encoder. The decoder will be enabling pixel-level localization at the definite precision level by an average ensemble of segmentation models. The ensembled pre-trained models will provide better training and prediction of abnormal structures in MRI images and thresholds for multi-classification of medical image visualization. The proposed model results in mean accuracy of 99.24 on the Kaggle dataset with 3064 images with a mean Dice score coefficient (DSC) of 0.9124 which is being compared with two state-of-art neural models.

Published: January 2023

Many scholars have utilized Bodalal’s mathematical model in the development of environmentally friendly building materials to describe the physical diffusion process of volatile organic compounds. In the model, the key to calculating the diffusion coefficient of volatile organic compounds in building materials is the value of the auxiliary parameter α1 and q. This paper improves the method of solving auxiliary parameter values by using extreme value theory. Several other calculation methods are also presented. The process of solving it is explained in detail, and an example is used to verify its accuracy. As these methods are very easy to learn and easy to implement on a computer, they can greatly reduce error rates, which makes them popular and useful.

Published: January 2023

Robots are widely used in all walks of life, and their excellent work efficiency has been paid attention to. As the key component of robot, manipulator plays an important role in the running performance of robot. In order to effectively improve the trajectory accuracy and efficiency of the manipulator, a six degree of freedom (6-DOF) modular manipulator trajectory planning method based on polynomial interpolation is proposed, and its feasibility and effectiveness are verified by experiments. At the same time, the performance of the method is compared with two other methods of the same type. The experimental results show that the six degree of freedom modular trajectory planning method has a shorter running time, and the shortest running time is 1.62 s. Compared with the directions in previous studies, the planning trajectory of the proposed method is more practical and its accuracy is higher. In the iterative process, the running time of the proposed method is also the shortest. In addition, the minimum error of the three methods is about 1%, which is lower than the other two methods. It is concluded that the six degree of freedom modular trajectory planning method has high feasibility and performance, which is of great significance to improve the operating efficiency and stability of the robot.

Authors: Li Cong
Published: January 2023

In order to improve the recognition effect of laser images, this study designed an intelligent recognition method of laser images based on big data analysis technology. On the basis of setting up the laser holographic scanning device and parameters, the laser image is obtained by using the calibration method of vision system. In order to avoid the limitation of coordinate system in the process of laser image recognition, a rational function model with general attributes is constructed. Then, convolutional neural network is used to output the feature data of laser images, and Spark parallel support vector machine algorithm is used to complete the classification of laser images. Finally, the SVM classification model based on the big data analysis technology is constructed. The texture feature data can be input to quickly output the classification results of laser images, and then the intelligent classification and recognition of laser images can be realized according to the probability distribution. Experimental results show that this method can accurately identify the tiny features in laser images, and the recognition results have high peak signal-to-noise ratio and high recognition accuracy.

Published: January 2023

One of the largest water consumers among public institutions, hospitals are characterized by water usage for various functions. Therefore, the nuanced water use requires a special methodology to determine the hospital water conservation efficiency. Based on the method of “water consumption-influencing factors in the base period”, we constructed a model for calculating the water savings amount at hospitals and demonstrated its applicability by exploring two case studies. The proposed method can help hospitals to accurately calculate the amount of water savings and determine their water conservation potential, thus evaluating the effects of the implemented water conservation measures, and achieving their targets.

Authors: Maisikeli Sayyed G.
Published: January 2023

BACKGROUND: Thousands of United Arab Emirates (UAE) citizens are living with physical challenge that render them incapable of performing routine activities the rest of us take for granted. OBJECTIVE: This paper investigated utilization of currently available and emerging assistive technologies, and examined the level of awareness of such technologies among the physically challenged population in the United Arab Emirates (UAE). Knowing the level of awareness and usage of assistive technologies can phase the way for governments, and other stakeholders to develop effective policies that are capable of improving the lives of the physically challenged population. METHODS: This research conducted a survey of a total of 50 participants (30 females and 20 males) with varieties of physical disabilities. The data collected from the survey participants were tallied by counting the number of participants’ response to series of simple Yes/No questions. RESULTS: Results have shown that only 40% are currently using assistive technologies; with 61.2% being aware of existing assistive technologies. The most identified currently available assistive technologies among survey participants are the wheelchair and transportation vans, and the least identified emerging technologies are systems that respond to head nod. With regards to the newly emerging technologies, only 10% of participants are aware of them, with (70%) willing to use the newly emerging technologies if made available. Also, 60% of the participants benefit from government assistance, and 40% from both philanthropic and family support. With regards to employability, only 2% are fully employed. CONCLUSIONS: The overall low-level of awareness of (both currently available and emerging assistive technologies) observed is an indication of the need for substantial work that needs to be done towards creating an effective awareness program capable of increasing the overall utilization of assistive technologies.

Published: January 2023

BACKGROUND: Paddy milling is the oldest and largest agro-processing industry in India. A large number of workers are employed in the rice mills where they are potentially exposed to dust. It has been shown that exposure to dust results in a high prevalence of respiratory diseases, such as asthma, chronic bronchitis, extrinsic allergic alveoli ties, toxic syndrome, and interstitial lung disease. OBJECTIVE: The aim of this study was to investigate the effect of dust on rice mill workers’ health using lung function tests with comparison to an unexposed population. PARTICIPANTS: Two hundred eighteen rice mill workers (exposed volunteers) were randomly selected from 25 rice mills in Assam, India. Participants were 18-60 years with at least one year of work experience. Further, 377 volunteers who were not exposed to dust and having similar demographic characteristics also participated as a control group. METHOD: Pulmonary function tests were conducted for all participants by spirometry. The tests included forced vital capacity (FVC), forced expiratory volume in one second (FEV1), FEV1/FVC (%), peak expiratory flow (PEF) and forced expiratory flow during the middle half of a forced vital capacity (FEF25-75%). Values from exposed workers were compared with the unexposed volunteers. RESULTS: It was observed that the lung function parameters FVC, FEV1, PEF and FEF25-75% in exposed workers were significantly decreased compared with unexposed volunteers. There were also significantly decreased FVC, FEV1, FEV1/FVC%, PEF and FEF25-75% with increase in age and duration of dust exposure. It was further observed that 48% and 32% of the total male and female volunteers, respectively, had evidence of lung disease. Irrespective of gender, approximately 45% of mill workers had evidence of lung disease, of which 21% was restrictive and 24% was obstructive. CONCLUSION: Compared with unexposed controls, rice mill workers have a greater prevalence of respiratory disease based on pulmonary function tests.

BACKGROUND: The demand for innovation and satisfaction is increasing rapidly due to technological advancement and the fast-changing business environment. OBJECTIVE: The purpose of this article is to investigate how job crafting augments work outputs (i.e., innovation performance and career satisfaction) through work engagement. METHODS: Data were collected from 477 workers working in the Pakistan manufacturing sector. A structural equation modeling technique was used to investigate the mediation model. RESULTS: Job crafting has a direct and indirect association with innovation performance and career satisfaction – via employees’ work engagement. Additionally, the mediating impact was stronger for innovation performance than for career satisfaction. The findings advocate that managers should pay attention to employees’ job crafting to improve employees’ work engagement in manufacturing organizations. To improve employees’ innovation performance and career satisfaction via work engagement, it is important to improve organization-wide job crafting in traditional manufacturing organizations. Strategic and managerial actions related to job crafting might boost employees’ engagement in the organization that environments provide incessantly better outcomes. CONCLUSION: By linking job crafting and work engagement to their attitude towards career satisfaction and innovation performance in Pakistani manufacturing firms, this study adds a new dimension to the study of Pakistani manufacturing employees and typically to the best practices in career debates. This knowledge is important and unique because it accentuates that in addition to work engagement, which focuses primarily on employee growth in the organization, job crafting should also be given equal importance to advance manufacturing employees’ outcomes.

This study investigates the difficulties in teaching nahwu using the blended learning method in the Arabic Language and Literature Study Program (BSA), Faculty of Islamic Studies, Universitas Ahmad Dahlan, amidst the COVID-19 pandemic. The primary data was collected by interviewing six BSA lecturers and four BSA students in the first semester of the academic year of 2021/2022. The interpretative phenomenological analysis (IPA) was utilized to analyze the data. The data analysis resulted in the following findings. It can be determined that the implementation of blended learning in the Arabic Language and Literature Study Program of Universitas Ahmad Dahlan used a two-class method, with online and offline classes. Students in online nahwu classes endured several difficulties, including unstable internet connections, non-interactive teaching methods, and lecturers’ inability to control all their students’ conditions. Meanwhile, students in offline nahwu classes underwent difficulties such as limited study time during class. The lecturers also experienced a similar difficulty when teaching students new to the Arabic language, as learning the principles of nahwu required a lengthy time. In addition, the lecturers felt uneasy when explaining the learning materials while wearing masks.
