Authors: Rahmat Saepul , Prima Dewi Riyani , Abdi Musyafiq Afrizal , Purnata Hendi
Published: January 2023

Electrical energy is one of the most important energies in everyday life so high-voltage electrical equipment has a vital role in maintaining the reliability of electric power distribution. The corona effect is caused by insulation failure in high-rise equipment which results in disrupted electrical power distribution. The purpose of this research activity is to produce a multi-sensor tool to test the condition of equipment in distribution network booths that have experienced the corona phenomenon. The input data from several sensors used, such as the ozone sensor, will detect ozone gas exposed in the 20kv chamber, detection of ultraviolet light by the UV sensor module, and detection of sound frequency from the hissing of equipment through the microphone sensor experiencing corona will be processed by the Microcontroller and if the value is detected exceeds the reference value that has been set, the output in the form of an LCD will display a corona symptom warning message and instruct the buzzer alarm to sound. The results showed that the prototype of the corona detector was able to identify ozone levels with a maximum value of 21.88 ppb, the largest UV index value of 336, and a maximum hissing frequency of 157 dB in distribution cubicles that experienced the corona effect.

Authors: Shekhovtsova-Burianova Viktoriia
Published: January 2023

The article analyzes the relationship between language and identity in Ukraine. The role of language as a source of the spiritual life of the people, a determining factor and the main sign of the identity of the Ukrainian nation is highlighted. The interrelationship of language as a factor in the formation of the identity of the Ukrainian nation is analyzed. The purpose of the article is to analyze the linguistic aspect as the main feature of the identity of the Ukrainian nation. Language is a means of forming and becoming a person, his intellect, will, feelings and form of existence. Language is a tool with which you can learn about the world around you. One of the main functions of language is identification. The function of linguistic identification is that language is a means of identification of speakers, that is, a means of expressing their belonging to the community, nation and ethnicity. In the process of national identification, the linguistic self-identification of each individual plays a major role, because it becomes the factor of the consolidation of society and the engine of building a strong, democratic and independent country. According to the concept of state language policy in Ukraine, the statehood of the Ukrainian language is a key factor in the consolidation of Ukrainian society throughout the territory of Ukraine, a guarantee of preserving the national identity of the Ukrainian ethnic group and the state unity of Ukraine. The results of the sociological survey showed that 94.6 consider Ukrainian as their native language and 64.9 speak exclusively Ukrainian; 97.3% of respondents believe that they are fluent in the Ukrainian language. The Ukrainian language is part of the XXI century. as a language that successfully meets the complex, responsible and multifaceted needs of the state and ethno-cultural development of the Ukrainian people, has a functionally dynamic and open structure for further development.

Authors: Boyarchuk Serhii , Vakulenko Vitaliy
Published: January 2023

Solving the problem of the formation of academic texts is one of the keys to creating an effective system for ensuring the quality of education and science. Today, these questions are the subject of research by both foreign and domestic scientists, since the peculiarities of creating academic texts are a multifaceted and complex phenomenon. The research used general scientific (generalization, comparison, induction and deduction) and empirical-theoretical methods (analysis, synthesis). The use of system-structural analysis made it possible to distinguish the main features of the creation of academic texts, their structure and preparation for publication. It has been established that writing one's own original academic texts according to the provided recommendations and samples, typical turns of speech, and established verbal constructions can be an effective way to implement academic writing. It was found that the main principles of constructing academic texts are the principle of triads, the non-linear principle, and the composite principle. It is determined that any scientist aims to solve one or more problems of scientific research, which in most cases arise from the needs of the development of society and its individual individuals, within the limits of a defined scientific direction. On the basis of the conducted research, it was found that the correct, justified choice of the problem of scientific research is determined by the guarantee of its future successful completion. The results can be directed to the further research of key aspects of academic integrity in the process of formation of academic texts.

Education is a sphere among a lot of society activities, which is very sensitive to geopolitical changes. The war in Ukraine has influenced educational preferences. Higher education must remain open, global and international regardless boundaries. Education is a sphere among a lot of society activities, which is very sensitive to geopolitical changes. The war in Ukraine has influenced educational preferences. Higher education must remain open, global and international regardless boundaries. The aim is to find out cultural challenges and ways to overcome them. In order to achieve the aim there are 3 tasks: 1. to establish whether there is a difference between host students and international students; 2. to formulate a complete model of cultural adaptation, 3. to explore the hypothesis of "cultural fit" in relation to self-interpretation. The study was conducted online among former students and current teachers of the Kamianets-Podilsky Ivan Ohienko National University due to the fact that during the war in Ukraine recipients are not available in person. Two groups of people participated in data collection for this study. The survey involved 5 teachers of foreign languages of the university and 10 foreign students who have already completed the programs. All respondents voluntarily participated in the survey; they were informed of the purpose of the capture and guaranteed anonymity. The obtained results show that students and teachers stressed the importance of developing speech and communication skills through organizing a conversation club and organizing events dedicated to Ukrainian culture (festivals, concerts). Such extra-curricular activities can be useful for students, as representatives of different cultures will be involved; this will force them to communicate and work together, preventing them from communicating with each other. Therefore, cultural adaptation is a type of interaction of a student with the educational environment of an educational institution, during which the subject's requirements and expectations are reconciled with his/her capabilities and objective reality. Knowing the cultural characteristics of different nations, one can explain this or that behavior of individual people, and therefore find solutions to overcome possible misunderstandings caused by cultural characteristics. Intercultural communication affects all areas of students’ activities in the process of education.

Authors: Sovhira Svitlana , Yashnyk S.V.
Published: January 2023

The article shows the methodological foundation for the formation of ecological culture and ecological professional competence of future specialists. The possibilities of the cultural approach as a content basis, a methodological message for the development and implementation of a competence-oriented educational process, which is aimed at the formation of a future specialist in ecological culture and ecological professional competence, are considered. It has been established that the competence approach in modern professional humanitarian education allows the student to form an individual ecological-educational space, organizing his personal experience and projecting his ecological-professional competence. It is revealed that the cultural approach to education today finds its partial solution in the implementation of the ideas of the competence approach, which corresponds to the leading idea of our research that the competence approach to humanitarian education allows the student to form an individual ecological and educational (eco-cultural) space through the development of his personal and professional activity. It has been proved that the concept of "ecological culture of the individual" characterizes the conceptual goal of modeling the educational process for the formation of the ecological professional competence of the future specialist. The position of the author's concepts regarding the essence of ecological culture in psychological, ethical, sociocultural, pedagogical and philosophical aspects is highlighted. It is revealed that ecological culture is a qualitatively new culture of the individual, which fills the properties of its relations with the surrounding socio-natural environment with a specific (depending on the level of ecological culture) content. It was established that there is a methodological connection between the concepts of "ecological culture" and "ecological-professional competence" as the attitude of the whole to its part. Environmental professional competence was considered as the ability and readiness of future specialists to design and organize environmental activities based on the application of socio-ecological knowledge, the manifestation of evaluative judgments about nature and ecological activities, mastering ecological actions and skills of an ecological nature.

Authors: Zhou Yongqiang , Chen Yimiao , Sun Chunsheng , Zhang Qinhe
Published: January 2023

Abstract: Internal fixation with steel plates is a common method for the therapy of lower limb fractures. Due to the disadvantages of traditional surgical methods such as high trauma and complications, the application of robots for minimally invasive surgery has become a popular research direction. In this article, we have designed and simulated the overall structure of a steel plate internal fixation device used in conjunction with a robotic arm. Firstly, a finite element model of cortical bone drilling was established based on ABAQUS to obtain the torque and axial force when drilling the cortical bone. Then a virtual prototype of the robot-assisted lower limb bone fracture plate internal fixation device was designed, and the outer shell, drilling mechanism, nail placement mechanism, nail supply mechanism, drive mechanism, and guide sleeve were refined based on the overall mechanical structure of the device, so that the device could continuously perform drilling and nail placement. Afterward, the device was simulated based on ADAMS, and the motion curves of each component were obtained to verify the feasibility of the device’s working principle and to validate the performance of the servo. Finally, the modal analysis of the device was carried out with the finite element software ABAQUS, and the modal parameters of the first six orders were obtained, which were compared with the operating frequencies of the motor and the servo to verify that the device is not easy to resonate during normal operation, and the static strength checks of the key components were carried out, and the stress and deformation clouds and upper limits of flexural values of the components were obtained, which proved that the structure has stability.

Published: January 2023

Background: although breast cancer in young women is less common and often overlooked, it is still considered a major health concern.Objectives: to evaluate the demographic, clinical, radiological and histopathological characteristics of breast cancer among a sample of Iraqi women diagnosed under the age of 40 years.Patients and methods: a retrospective study enrolled 73 females below the age of 40 years with a history of breast cancer. All data was extracted from an established information system database designed by the Principal Investigator of the Iraqi National Breast Cancer Research Project under supervision of the International Agency for Research on Cancer (IARC) over a 4-years period from 2011 to 2014.Results: seventy three women under the age of 40 years with breast cancer were included in the study out of 625 diagnosed cases at different ages (11.68%). The age at presentation ranged from 25 to 39 years, the peak age frequency (63%) was recorded in the period between 35-39 years (n=46). Family history of breast cancer was noticed in approximately 31.5% of cases (n=23). Early menarche (less than 12 years old) was detected in 78.1% (n=57) of cases. On examination, 90.4% (n=66) of patients had painless palpable breast lump. By Sonography, the lesions were spiculated margins in 52% (n=38) of patients and echogenic halo around the mass was detected in 57.5% (n=42) of cases. Stage-II disease was recognized in 54.8%(n=40) of sample of the study and majority of the tumor (98.6%) were ductal in origin. According to Scarf- Bloom-Richardson method, 60.3% (n=44) of the tumors were moderately differentiated (i.e. grade- II). Eight patients (10.9%) were presented with triple receptor-negative breast cancer and recurrence of tumor was encountered in 17.8% (n=13) of cases.Conclusions: The current study suggest that breast cancer among young Iraqi women under 40 years had high incidence rate but might be less aggressive than what is reported in western countries despite of high recurrence rate.

The Role of Action Research in Democratizing Governance: The Case of Bilbao Next Lab
Authors: Oliva Peirano Joaquín Gregorio
Published: January 2023

The aim of this study is to analyze how Action Research for Territorial Development (ARTD) promotes democratization in governance spaces. Considering the declared democratic intention of action research (AR) (Gustavsen, 2017; Palshaugen, 2014), ARTD is not an exception (Larrea, 2019). However, this specific relation with democratization has not been yet analyzed, nor measured in ARTD. In a context in which the number of countries categorized as free is at its lowest level in the 21st century (The Freedom House, 2021), the main contribution of this paper is the construction of a new analytical framework in order to assess the degree of democratization in ARTD processes. This analytical framework can be useful for other approaches to AR as well. More specifically, the most important contribution is the analysis of how ARTD may be facilitating such processes. This investigation studies governance at the Bilbao Next Lab, an AR laboratory focused on urban policy making in the Basque Country, Spain. This process is being facilitated through ARTD by the Basque Institute of Competitiveness – Orkestra in alliance with the local government, the Bilbao City Council and its economic development agency, Bilbao Ekintza. The case shows, together with new democratization dimensions analyzed, a deep and diverse bonding system between ARTD and democratization, in which the democratization factors hold to all ARTD elements. The paper discusses how the core ARTD elements are promoting the development of what are considered in theory as democratization factors.
Healing assessment trauma: an experience of mutuality in Action Research
Authors: Cuizon Reynaldo O.
Published: January 2023

Learning assessment is a pedagogical reality such as in teaching professional education courses with preservice education students. Assessment problems like horrifying and boring test papers must be addressed because these cause trauma to learners. Using an Action Research Method, I subjected my test materials to democratic critiquing and enhancement process, taking-into account the experiences of my learners and the viewpoints of my colleagues as my study participants. Said materials were utilized as my pedagogical action to address student assessment animosity. The results made me discern that though the contents of my test papers were aligned with the learning outcomes defined by the Commission on Higher Education, they were merely words and sentences in monotone appearance and thus, not eye-catching. Consequently, I crafted a Holistic Written Assessment Guide (HWAG) ensuring in test paper construction the pedagogical values of multiple intelligences, learning taxonomies, grammar review necessity, proper coverage and level of difficulty sequencing and marking, and time-number of items balance. Utilizing this new form and substance of my learning assessment material and engaging with it turned out to be liberating thus mutual healing to me as a transformed purveyor of education, to my students as healthy collaborators, creators and ultimate beneficiaries of learning, and to educators in the global environment as inspirers of democratic, equitable, and lifelong education. With this mutuality, this paper potentially enables leaders of nations to engage in the transformation of the pedagogical landscape.
Alles nur Zusammenbruch? Ein Vorschlag zur Anwendung des Weltökologie-Ansatzes für empirische Gegenwartsforschung
Authors: Anlauf Axel
Published: January 2023

Ausgehend von einer kurzen Darstellung zentraler Begriffe in dem von Jason Moore geprägten Weltökologie-Ansatz, bemüht sich der Artikel einige Missverständnisse in der deutschen Rezeptionsdebatte zu klären. Er zeigt, dass der Weltökologie-Ansatz nicht bloß eine (ökologische) Zusammenbruchs Theorie ist, sondern wichtige Impulse für die Forschung zu Ressourcenpolitik und globalen Ungleichheiten liefern kann. Ein zentraler Fokus liegt herbei auf dem Begriff der commodity frontier und der Aneignung natürlicher Ressourcen für die Kapitalakkumulation. Aufgrund der starken Strukturorientierung im Weltökologie-Ansatz, plädiert der Artikel für eine Weiterentwicklung um weitere Theorie-Stränge. Mit Hilfe der Forschung zu Warenketten bzw. Produktionsnetzwerken und der materialistischen Staatstheorie entwickelt er einen Forschungsrahmen, der es ermöglicht, gesellschaftliche Kräfteverhältnisse auf verschiedenen Ebenen in die Analyse von Rohstoffflüssen zu integrieren. Dies ebnet den Weg zu einer ergebnisoffenen Gegenwartsforschung und einer Operationalisierung abstrakter Kategorien wie cheap nature.
Die Rückgewinnung Colombos. Die postkoloniale Geopolitik der sri-lankischen Urbanisierung
Authors: Ward Shelby E. , Weerasuriya Ranitri
Published: January 2023

Dieser Beitrag befasst sich mit den Machtverhältnissen im Kontext mehrerer Immobilienprojekte in einem als „Downtown“ Colombo bezeichneten Gebiet. Solche Urbanisierungsprojekte versinnbildlichen die historisch gewachsenen postkolonialen Beziehungen in der sich globalisierenden Welt. Im Zentrum steht das von der chinesischen Regierung und Sri Lankas Ministerium für Megapolis und Westliche Entwicklung unterstützte „Colombo Port City“-Projekt, für das die Insel um 575 Hektar erweitert wurde. Es basiert auf einem 99-jährigen Pachtvertrag mit China für das „John Keels Cinnamon Life“-Projekt. Geplant sind ein großes Hotel, Wohnungen, Einkaufsmöglichkeiten, Restaurants und ein Casino. Durch das Projekt kam es zu Vertreibungen von Einzelpersonen oder Gemeinschaften aus dem Stadtteil „Slave Island“, die entweder durch behördliche Eingriffe erzwungen wurden oder Folge steigender Preise waren. Die Autorinnen zeichnen die Politik der Urbanisierung Colombos unter dem Prinzip der „Rückgewinnung“ nach. Dabei bezeichnet „Rückgewinnung“ sowohl die physische Aufschüttung und Trockenlegung von Land (physical reclaimed land) als auch die Rückforderung von Land aus den Vertreibungen (land reclaimed from the Slave Island evictions) und die weiter bestehende Möglichkeit, außergewöhnliche Herrschaftsgewalt für das „öffentliche Wohl“ auszuüben. Solche Investitionen und Partnerschaften deuten auf fortbestehende koloniale Machtverhältnisse ebenso hin wie auf den Versuch der sri-lankischen Regierung, eine Position als geostrategischer Partner in den internationalen Beziehungen erneut einzufordern. Nur eine von den makroökonomischen Ebene bis hin zur Mikroebene der Individuen reichende Sichtweise kann eine postkoloniale Kritik an der Globalisierung und der zeitgenössischen Geopolitik üben und alternative Modelle zu Fortschritt und südasiatischer Moderne bieten.

Authors: Garg Janvee , Singh Anil Kumar , Gupta Ashish
Published: January 2023

BACKGROUND/OBJECTIVE: In today’s volatile business environment, the competitive advantages of firms are temporary. The top management does not, and cannot, have all the answers to increasingly complex and rapidly changing problem situations facing their firms. Since the COVID-19 crisis, organizations have been under pressure to improve their knowledge management practices to continue creating value. Knowledge management capabilities are essential for business performance and competitive advantage. In order to ensure continuous value creation, we conducted research to identify various drivers and dimensions that were revitalized in the ongoing KM practices post-pandemic. METHODOLOGY: In this study, 81 research papers published between January 2010 and March 2022, have been examined from a knowledge management, human capital, and value creation perspective, aiming to understand how a firm can continue to create value before, during, and after the pandemic. RESULTS/CONCLUSION: Our review identifies critical factors in knowledge management and value creation and how companies generate value by leveraging KM during the COVID-19 pandemic. As a result of the research, the authors describe their findings in the form of a conceptual framework which deals with the various drivers and the factors within the KM architecture.

Authors: Li Tianqi , Pappas Colleen , Klinedinst Brandon , Pollpeter Amy , Larsen Brittany , Hoth Nathan , Anton Faith , Wang Qian , Willette Auriel A.
Published: January 2023

Background:

Insulin-like growth factor (IGF)-1 plays an important role in Alzheimer’s disease (AD) pathogenesis and increases disease risk. However, prior research examining IGF-1 levels and brain neural network activity is mixed.

Objective:

The present study investigated the relationship between IGF-1 levels and 21 neural networks, as measured by functional magnetic resonance imaging (fMRI) in 13,235 UK Biobank participants.

Methods:

Linear mixed models were used to regress IGF-1 against the intrinsic functional connectivity (i.e., degree of network activity) for each neural network. Interactions between IGF-1 and AD risk factors such as Apolipoprotein E4 ( APOE4) genotype, sex, AD family history, and age were also tested.

Results:

Higher IGF-1 was associated with more network activity in the right Executive Function neural network. IGF-1 interactions with APOE4 or sex implicated motor, primary/extrastriate visual, and executive function related neural networks. Neural network activity trends with increasing IGF-1 were different in different age groups. Higher IGF-1 levels relate to much more network activity in the Sensorimotor Network and Cerebellum Network in early-life participants (40–52 years old), compared with mid-life (52–59 years old) and late-life (59–70 years old) participants.

Conclusion:

These findings suggest that sex and APOE4 genotype may modify the relationship between IGF-1 and brain network activities related to visual, motor, and cognitive processing. Additionally, IGF-1 may have an age-dependent effect on neural network connectivity.
Etiology and Clinical Significance of Network Hyperexcitability in Alzheimer’s Disease: Unanswered Questions and Next Steps
Authors: Samudra Niyatee , Ranasinghe Kamalini , Kirsch Heidi , Rankin Katherine , Miller Bruce
Published: January 2023

Cortical network hyperexcitability related to synaptic dysfunction in Alzheimer’s disease (AD) is a potential target for therapeutic intervention. In recent years, there has been increased interest in the prevalence of silent seizures and interictal epileptiform discharges (IEDs, or seizure tendency), with both entities collectively termed “subclinical epileptiform activity” (SEA), on neurophysiologic studies in AD patients. SEA has been demonstrated to be common in AD, with prevalence estimates ranging between 22-54%. Converging lines of basic and clinical evidence imply that modifying a hyperexcitable state results in an improvement in cognition. In particular, though these results require further confirmation, post-hoc findings from a recent phase II clinical trial suggest a therapeutic effect with levetiracetam administration in patients with AD and IEDs. Here, we review key unanswered questions as well as potential clinical trial avenues. Specifically, we discuss postulated mechanisms and treatment of hyperexcitability in patients with AD, which are of interest in designing future disease-modifying therapies. Criteria to prompt screening and optimal screening methodology for hyperexcitability have yet to be defined, as does timing and personalization of therapeutic intervention.

Research on surface defects detection method and system in manufacturing processes based on the fusion of multi-scale features and semantic segmentation for intelligent manufacturing
Authors: Gong Yu , Liu Mingzhou , Wang Xiaoqiao , Liu Conghu , Hu Jing
Published: January 2023

Multi-scale defect features, blurred edges and inability to locate geometric features have been the three key factors limiting the detection of surface defects on quality control system in the industrial manufacturing process. In this study, a method based on the fusion of multi-scale features and pixel-level semantic segmentation is proposed for the detection of surface defects. The proposed method firstly fuses multi-level feature maps to balance the expressiveness of multi-scale features, then adds a boundary refinement module to enhance the accurate inference of edge fine-grained, and finally adopts an en-decoder architecture to locate geometric features at the pixel-level for each type of defects, realizing intelligent detection of geometric features of end-to-end multi-scale defects on the surface of parts. We conduct experiments using the collected parts datasets to evaluate the effectiveness of our framework. The experimental results show that the proposed model achieves MIoU of 80.1%, the recognition accuracy reaches more than 95 %, and a detection rate of up to 29.64 FPS, demonstrating the advancement and effectiveness of the proposed method with less misclassification and superior generalization performance and has progress and effectiveness in detecting surface defects of multi-scale features. It provides a research idea for the subsequent realization of surface quality inspection in the manufacturing process system.

Authors: Yu Hongliang , Peng Zhen , He Zirui , Huang Chun
Published: January 2023

In China, steel structure building has become an important direction of national support and development. As a link in steel structure construction, welding plays a vital role. With the continuous development of domestic steel structures in the direction of “big, special, and new”, manual welding becomes increasingly difficult. The application of robotic technology can effectively reduce the problems of unstable quality and low efficiency caused by manual welding. However, how to evaluate the overall application effect of this technology from the perspective of steel structure construction projects is an urgent problem to be solved at present. Through an in-depth analysis of the technology of building steel structure welding robots, combined with the idea of the capability maturity model and WSR methodology, the evaluation index system of application maturity of building steel structure welding robotic technology is designed. In addition, according to the gray, fuzzy, and difficult-to-quantify characteristics of the evaluation index system, the evaluation model of the application maturity of the building steel structure welding robot technology is established by using the subjective and objective combination weighting method and the gray system theory. In this model, the mixed weighting method of AHP and entropy weight method is used to determine the index weight, and then the multi-level gray theory is used to comprehensively evaluate the maturity of the technology application. Lastly, a project is used as an example to check the science and feasibility of the model.
Variational iteration method for solving uncertain differential equations
Authors: Li Wanping , Zhang Guidong , Sheng Yuhong
Published: January 2023

Solving uncertain differential equations is a critical subject in the field of uncertainty theory, where uncertain differential equations are a sort of differential equations that involve Liu processes. Currently, considerable effort has been put into addressing this issue. Regrettably, analytic solutions to uncertain differential equations are not always accessible. As a result, several numerical methods have been investigated. However, numerical methods have certain limitations in terms of providing a continuous representation of the solution as well as more information about the solution. This paper will propose a novel algorithm based on the variational iteration method (VIM) for solving uncertain differential equations analytically or approximately analytically. The associated numerical experiments show that the proposed method is an efficient tool for solving uncertain differential equations.

Published: January 2023

The diversity of attribute categories brings certain difficulties to data feature detection. In order to improve the accuracy and efficiency of feature detection, a hybrid attribute feature detection method for power system intelligent operation and maintenance big data based on improved random forest algorithm is proposed. Clustering processing power system intelligent operation and maintenance big data, based on data clustering results to reduce the characteristics of data mixed attributes, reduce the scale of data processing, and discretize the data mixed attributes; BP neural network is used to preprocess the results. Make corrections to improve the accuracy of feature detection, use the improved random forest algorithm to classify the data, and improve the convergence speed of the method. Finally, the support vector machine method is used to realize the feature detection of data mixed attributes. The experimental results show that the feature detection accuracy and efficiency of the method designed in this paper are high, and more features can be detected, which verifies its effectiveness. The method designed in this paper has the minimum RMSE value and the maximum value is only 0.12, which is far lower than the RMSE value of the improved spectral clustering algorithm and multi-domain feature extraction method, and has high detection accuracy.
Experimental and theoretical investigation of the effect of alkali (Li, Na and K) doping on the properties of nickel oxide thin films: Comparative study
Authors: Touhami Hanna , Almi Kenza , Lakel Said
Published: January 2023

Pure and 6% alkali-doped NiO thin films (alkali A = Li, Na, K) were prepared by a sol-gel spin coating method and deposited on glass substrates. XRD analysis showed that the prepared films belonged to a cubic structure with (111) plane as preferential growth orientation for undoped and K-doped samples and (200) for Li and Na doping. An optical study based on (UV-Visible) showed that the band gap tends to decrease with alkali doping and achieves a minimal value with Na doping. The Urbach energy increases systematically with the decrease of the optical band gap. The resistivity measurements showed that alkali doping led to a significant decrease in the resistivity value. The lowest value was achieved for the 6% Na-doped sample. Structural, optical and elastic properties of pure and 6% A-doped NiO were performed using the first principal method based on density functional theory. The optimization of the geometry of the studied samples revealed that the lattice parameters changed after doping. The band structure and density of states calculations showed that undoped and alkali doped samples exhibited an indirect band gap and the doped samples had comparatively narrower band gaps. The elastic constants Cij, Bulk modulus B, Shear modulus G, Young modulus, and Poison ratio of doped and alkali-doped NiO were further investigated.

Authors: Gamble Ryan , Sumner Petroc , Wilson-Smith Kevin , Derry-Sumner Hannah , Rajenderkumar Deepak , Powell Georgie
Published: January 2023

BACKGROUND: Persistent Postural-Perceptual Dizziness (PPPD) is a chronic neuro-vestibular condition characterised by subjective dizziness, non-spinning vertigo, and postural imbalance. Symptoms are typically induced by situations of visuo-vestibular conflict and intense visual-motion. OBJECTIVE: Little research has focused on the lived experiences of people with PPPD. Therefore, our objective was to present an in-depth exploration of patient experiences and sense-making, and the effect of PPPD on psycho-social functioning. METHODS: We conducted semi-structured interviews with 6 people with PPPD, who were recruited from an Audiovestibular department in Wales. We present a case-by-case Interpretive Phenomenological Analysis (IPA) for each participant and present common themes. RESULTS: Our analysis revealed a range of superordinate and subordinate themes, individualised to each participant, but broadly described under the following headings: dismissal and non-belief, identity loss, dissociative experiences, poor psychological well-being and processes of sense-making. CONCLUSION: The qualitative experiences documented in this study will help clinicians and researchers to better understand the lived experiences of PPPD, how PPPD patients make sense of their symptoms, and the psycho-social impacts of the condition.
Performance evaluation and comparative analysis of CrowWhale-energy and trust aware multicast routing algorithm
Authors: Shende Dipali K. , Angal Yogesh S.
Published: January 2023

Multipath routing helps to establish various quality of service parameters, which is significant in helping multimedia broadcasting in the Internet of Things (IoT). Traditional multicast routing in IoT mainly concentrates on ad hoc sensor networking environments, which are not approachable and vigorous enough for assisting multimedia applications in an IoT environment. For resolving the challenging issues of multicast routing in IoT, CrowWhale-energy and trust-aware multicast routing (CrowWhale-ETR) have been devised. In this research, the routing performance of CrowWhale-ETR is analyzed by comparing it with optimization-based routing, routing protocols, and objective functions. Here, the optimization-based algorithm, namely the Spider Monkey Optimization algorithm (SMO), Whale Optimization Algorithm (WOA), Dolphin Echolocation Optimization (DEO) algorithm, Water Wave Optimization (WWO) algorithm, Crow Search Algorithm (CSA), and, routing protocols, like Ad hoc On-Demand Distance Vector (AODV), CTrust-RPL, Energy-Harvesting-Aware Routing Algorithm (EHARA), light-weight trust-based Quality of Service (QoS) routing, and Energy-awareness Load Balancing-Faster Local Repair (ELB-FLR) and the objective functions, such as energy, distance, delay, trust, link lifetime (LLT) and EDDTL (all objectives) are utilized for comparing the performance of CrowWhale-ETR. In addition, the performance of CrowWhale-ETR is analyzed in terms of delay, detection rate, energy, Packet Delivery Ratio (PDR), and throughput, and it achieved better values of 0.539 s, 0.628, 78.42%, 0.871, and 0.759 using EDDTL as fitness.

BACKGROUND: The data mining of construction accidents based on a robust modeling process can be used as a practical technique for reducing the frequency of construction accidents. OBJECTIVE: This study was designed to data-mine construction accidents. METHODS: This study was conducted in 2020 on construction accidents in Iran for ten years (2009–2018). The instruments to collect the required data were the checklists and descriptive reports of the accidents. The dependent variables of the study included reactive safety indicators related to construction accidents (lost working days (LWD) and total accident costs (TAC)). The independent variables consisted of four latent factors: personal variables, organizational variables, unsafe working conditions, and unsafe acts. The data were collected based on the conceptual model designed for data mining. The data mining process was carried out based on the structural equation modeling by IBM AMOS V. 23.0. RESULTS: A total of 5742 construction accidents occurring in 10 years were analyzed. The means of TAC and LWD indicators were estimated to be 248.20±52.60 days and 1893.10±152.22 $. These two indicators directly correlated with the two latent factors of unsafe conditions and unsafe acts and their related variables and were indirectly influenced by latent personal and organizational factors. The relationship between unsafe conditions and unsafe acts was significantly positive. The relationship between latent personal and organizational factors and the two construction accident indicators was significantly negative (p <0.05). CONCLUSION: The model results showed that personal and organizational variables could, directly and indirectly, affect reactive safety indicators in construction projects. Thus, these findings can be used to design and improve safety strategies to prevent and decrease construction accidents and incidents.

Статтю присвячено розробленню теоретичних та методологічних засад проєктування нового підручника з інтегрованого курсу історії та громадянської освіти для 5-го класу «Досліджуємо історію і суспільство». Підручник створено за вимогами Державного стандарту освіти України (2020), що обумовлює подальше реформування базової ланки середньої освіти на засадах Нової української школи, та реалізації цих ідей у Типових освітніх програмах та модельних навчальних програмах з предметів і курсів 5‒6 класів. Аналіз названих документів засвідчує кардинальні зміни змісту і підходів до навчання учнів на базовому рівні освіти, серед яких: активна інтеграція предметного змісту як у середині освітніх галузей, так і міжгалузева, перехід до активної моделі навчання із застосуванням відповідних видів діяльності учнів, адаптаційний характер курсів 5-го та 6-го класів, орієнтація навчання на формування ключових компетентностей і наскрізних умінь учнів.
ПІДТРИМКА ЄС ІНТЕГРАЦІЇ УКРАЇНСЬКИХ ДІТЕЙ І МОЛОДІ В СИСТЕМИ ОСВІТИ ДЕРЖАВ-ЧЛЕНІВ В УМОВАХ ВІЙНИ РФ ПРОТИ УКРАЇНИ: СТРАТЕГІЧНІ ОРІЄНТИРИ ТА УСПІШНІ ПРАКТИКИ

Статтю присвячено аналізу освітньої політики країн-членів ЄС з питань інтеграції українських дітей-біженців в європейський освітній простів. З’ясовано, що з початком війни росії проти України держави ЄС активно підтримують нашу державу, у тому числі й у галузі освіти. Досліджено модель інтеграції українських дітей-біженців в освітній процес країн-членів ЄС та виявлено, що вона спрямована на задоволення навчальних, соціальних та емоційних потреб. Відповідно до інтеграційної моделі вивчено ключові напрями діяльності, що передбачають зарахування учнів-мігрантів шляхом розширення інфраструктури та усунення можливих перепон; підготовка освітніх закладів та персоналу; адаптація систем освіти до включення українських педагогів; цільові заходи щодо інтеграції дітей-біженців; соціально-психологічна підтримка учнів, їх родин та громад біженців; довгострокові заходи щодо інклюзивної освіти; освіта і догляд для дітей раннього та дошкільного віку. Проаналізовано політичні рішення окремих країн ЄС щодо залучення українських учнів-мігрантів та вчителів до освітнього процесу на місцевому та найвищому рівнях. З’ясовано, що початковий етап інтеграції передбачає оцінювання мовних компетентностей та розробку подальших заходів щодо підтримки учнів з недостатніми мовними навичками. Встановлено, що в окремих країнах ЄС додатково проводиться оцінювання загального рівня навчальних досягнень учнів. Виявлено, що в ситуації з українськими дітьми існує практика оцінювання соціально-психологічних потреб, в окремих країнах розроблено спеціальні інструменти їх задоволення. Визначено, що інтеграція українських дітей в освіту країн ЄС відбувається в таких форматах: окремі класи для учнів-мігрантів, де освітній процес переважно спрямований на опанування мови навчання; окремі класи для учнів-мігрантів з можливістю опановувати окремі дисципліни (мистецтво, музика) в загальних класах; звичайні класи з додатковими мовними курсами для учнів-мігрантів; дистанційне навчання на українських освітніх платформах. Підкреслено, що переважна більшість освітніх систем ЄС підтримує формат звичайного класу, надаючи учням-мігрантам додаткову мовну підтримку. Констатовано, що інтеграційна підтримка спрямована також на педагогічних працівників з України, для яких в країнах ЄС розроблені додаткові правові регулювання найму. Зроблено висновок, що освітня політика ЄС передбачає для дітей-біженців з України можливість інтегруватися в освітній простір країн-членів. Продовження онлайн освіти в Україні є відкритим питанням, яке продовжує розроблятися державами відповідно до національної специфіки.
МІНІМІЗАЦІЯ ОСВІТНІХ ВТРАТ УЧНІВ ЗАКЛАДІВ ЗАГАЛЬНОЇ СЕРЕДНЬОЇ ОСВІТИ В УМОВАХ ВОЄННОГО СТАНУ: ЗМІШАНЕ НАВЧАННЯ

Проблема організації та здійснення змішаного навчання не є новою для педагогічної науки загалом та в контексті реалізації освітнього процесу в закладах середньої освіти зокрема. В умовах воєнного стану актуалізується вивчення питань щодо обґрунтування доцільності застосування в освітньому процесі закладу загальної середньої освіти новітніх методологічних підходів, моделей, технологій, форм організації, методів, прийомів і засобів змішаного навчання, пов’язаних із імплементацією основних положень компетентнісно орієнтованої освіти під впливом непередбачуваних глобальних впливів. Ключовим завданням організації освітнього процесу в закладах загальної середньої освіти в умовах воєнного стану та в повоєнний період є мінімізація освітніх втрат учнів як центральних суб’єктів здобуття освіти. Саме змішане навчання розуміємо як форму організації освітнього процесу, яка гармонійно поєднує наявний досвід провадження освітнього процесу в класичному форматі та досягнень сучасної педагогічної науки щодо здійснення освітнього процесу в дистанційному форматі, що спрямовується на підтримання належного рівня надання освітніх послуг здобувачам освіти. Автори дослідження наголошують на необхідності визначення та нагальній потребі максимально швидкого розв’язання психолого-дидактичних задач, пов’язаних із провадженням змішаного навчання в закладах загальної середньої освіти загалом та в умовах воєнного стану зокрема (урахування об’єктивно обумовлених причин та чинників, що можуть виявлятися як деструктивні щодо здобуття якісної освіти в закладах загальної середньої освіти) з перспективою їх подальшого вивчення у повоєнний період.
