Possibilities of using the virtual simulator "Vimedix 3.2" in the process of training in the specialty "ultrasound and diagnostics"

Background. In recent years, it is important to change the methods and programs of teaching many disciplines, including ultrasound diagnostics, with the inclusion of various virtual and simula-tion devices. The practical experience of using such technologies in the teaching process is rather short, therefore, there are few original works devoted to this topic in Russian and foreign literature.Aims. To determine the possibilities and algorithm of using virtual simulator of ultrasound re-search in the process of teaching the discipline of "ultrasound diagnostics" on the basis of the results of work with it. To evaluate the advantages and disadvantages of using simulator in comparison with traditional teaching methods.Material and methods. The results of using the virtual simulator "Vimedix 3.2" in the educa-tional process were analyzed. Simulations of transabdominal ultrasound examination of abdominal cavity organs, transthoracic echocardiography, triplex scanning of main vessels were performed on it. The study involved 26 residents in the specialty "ultrasound diagnostics", as well as 47 physicians who were trained at professional retraining courses.Results. The use of a virtual simulator at the initial stage in the training process can eliminate many of the problems that residents and trainees encounter in clinical sites. The use of a simulator in the testing process seems to be less favorable than a practical examination using ultrasound scanners and real patients.Conclusions. It is advisable to use the simulator at the initial stage to practice the research methodology. It is recommended to develop and use additional teaching materials and programs in training. The advantages of the virtual simulator are comfort of work at the initial stage of training, short time of its mastering, availability of an extensive database of pathological cases. The identified non-critical deficiencies require correction during further training in the clinic.

JAK-inhibitors in the therapy of comorbid diseases – atopic dermatitis and alopecia areata: literature review and experience of clinical practice

Atopic dermatitis (AtD) is currently considered as a systemic disease due to the fact, that disorders of innate and adaptive immune response, especially pronounced in severe course, are manifested not only in skin inflammation, but also can be realized in the development of other chronic diseases, including autoimmune profile. One of the autoimmune comorbid diseases in AtD is alopecia areata (AA), which is confirmed by epidemiologic data, clinical features and identification of common immune links of pathogenesis in the case of association of these diseases. Janus-kinase inhibitors, which represent a new class of targeted synthetic basic anti-inflammatory drugs, are currently the main pathogenetic treatments for severe forms of AtD and AA. Acting on several immune axes, these drugs selectively and reversibly modulate the signaling activity of key inflammatory cytokines, which makes them the most promising strategy for systemic therapy of these dermatoses, including in cases of their combination. The article covers the review of pathophysiology and application of first and second generation JAK-inhibitors in AtD and AA, including the analysis of their efficacy in the simultaneous presence of these pathological conditions. We present own observations of two patients with severe comorbid conditions AtD and AA, treated with the JAK-inhibitors abrocitinib and upadacitinib. These examples confirm the efficacy of Janus-kinase inhibitors in AtD and AA in real clinical practice and describe the experience of switching from one JAK-inhibitor of the first generation to another, selective JAK-inhibitor, as well as the effect of of these drugs on the course of both pathologies. Taking into account the necessity of long-term use of JAK-inhibitors, further study of their long-term efficacy and safety remains relevant.

A Method for Image-Based Interpretation of the Pulverized Coal Cloud in the Blast Furnace Tuyeres

The conditions in the combustion zones, i.e., the raceways, are crucial for the operation of the blast furnace. In recent years, advancements in tuyere cameras and image processing and interpretation techniques have provided a better means by which to obtain information from this region of the furnace. In this study, a comprehensive approach is proposed to visually monitor the status of the pulverized coal cloud at the tuyeres based on a carefully designed processing strategy. Firstly, tuyere images are preprocessed to remove noise and enhance image quality, applying the adaptive Otsu algorithm to detect the edges of the coal cloud, enabling precise delineation of the pulverized coal region. Next, a Swin–Unet model, which combines the strengths of Swin Transformer and U-Net architecture, is employed for accurate segmentation of the coal cloud area. The extracted pulverized coal cloud features are analyzed using RGB super-pixel weighting, which takes into account the variations in color within the cloud region. It is demonstrated that the pulverized coal injection rate shows a correlation with the state of the cloud detected based on the images. The effectiveness of this visual monitoring method is validated using real-world data obtained from a blast furnace of SSAB Europe. The experimental results align with earlier research findings and practical operational experience.

Ensuring sustainable development by prioritizing national economic interests

Aim. To develop recommendations on the formation of a national model of sustainable development of the Russian economy based on the identification of its key vectors, components in the conditions of external and internal shocks and changes caused by the transformation of strategic guidelines for sustainable development.Objectives. To analyze the peculiarities of the implementation of the global concept of sustainable development of the United Nations (UN) under the influence of deglobalization processes; to substantiate the need to transform the established foundations of sustainable development of economic systems in order to ensure the national economic interests of Russia; to propose the author’s approach to the formation of the structure and content of the national model of sustainable development of economic systems; to build a scheme of interaction between different levels of the economic system, ensuring the development of the national model of sustainable development of economic systems.Methods. In the course of the research we applied general scientific methods and techniques: analysis and synthesis, generalization of practical experience, expert assessments, comparison, abstraction and concretization, monitoring, modeling.Results. Based on the analysis of modern processes of deglobalization, the necessity of changing the structure and content of the concept of sustainable development of the Russian economy in the conditions of external shocks caused by the transformation of the global agenda of sustainable development was substantiated. The author’s approach to the formation of the structure and content of the national model of sustainable development of economic systems is proposed, which supplements the current triad of sustainable development (economy, ecology and social sphere) with innovation and institutional components and is scalable to the meso(regions) and micro-level (enterprises). The structure of the model sets socio-economic security, innovation security and the quality of the institutional environment in the conditions of external and internal shocks as controllable parameters, focusing on the creation of conditions for convergent convergence of meso-level systems. The scheme of organization of interaction between macro-, mesoand microlevels of the economic system is constructed, in which at the macrolevel the foundations of sustainable development of the country’s economy on the basis of national interests are set, management and control of mechanisms of sustainable development of economic systems of other levels are organized, and at the mesolevel the multiplier effect is provided for in the implementation of economic mechanisms of interaction of all elements of the regional ecosystem; the key task of the microlevel is the implementation of effective management of the regional ecosystem.Conclusions. Sustainable development of the Russian economy in the current conditions of global challenges is a complex task, the solution of which requires a systemic and holistic approach based on the prioritization of national economic interests. The proposed model, which determines the general guidelines at the macro level, suggests the organization of interaction of all three levels of the economy (macro-, mesoand micro-) with the provision of multiplier effect at the meso level, which requires the elaboration of adaptation mechanisms to the conditions of regional ecosystems and the specifics of business entities, suggests the continuation of the study.

Patient and public involvement in the development of the digital tool MyBoT to support communication between young people with a chronic condition and care providers.

To guide good practices in patient and public involvement (PPI), several calls have been made to share detailed accounts of practical experiences. We describe our collaboration with young people with a chronic condition (YPCC) in the development, testing and implementation of the digital communication tool MyBoT (Map your Burden of Treatment). MyBoT was developed by a team of academic researchers, some of whom were practising care providers, YPCC and designers. In addition to the two co-researchers in the research team, various groups of YPCC were involved in decision-making through participation in a design session, workshops and a dialogue session. The Involvement Matrix was used to reflect on the PPI of all YPCC. Initially, the two co-researchers were involved in the roles of informer and co-thinker, but their decision-making power within the study increased over time. In the final stages of the study, the co-researchers and researchers became partners. The other YPCC who participated in the different sessions and workshops were co-thinkers in all stages of the study. The PPI of two YPCCsas co-researchers within the research team ensured continuous involvement, whereas the PPI of various groups of YPCCsguaranteed a representative and inclusive approach. Researchers play an essential role in bringing all perspectives together, integrating them within the technical and financial constraints and ultimately building a tool that is tailored to its users' needs. YPCC played a significant role in the present study. Two YPCC-who are also co-authors of this paper-were involved in all stages of this project as members of the research team. In addition, various YPCCswere involved in the development, testing and implementation stage of MyBoT by organizing design sessions, workshops and a dialogue session.

Dynamics of teaching practice in South Africa: A nexus between theory and practice

Teaching practice is organized to prepare student-teachers by providing skilled supervision, practical experience, mentoring and support, collaborative learning, and insightful practice. However, it has been found that when student teachers embark on teaching practice, they find it hard to put into practice the theoretical knowledge they have acquired in teacher training institutions. The study aimed to explore how this program is organized to equip student-teachers with skills for handling learners' academic needs in schools, the challenges encountered by student-teachers during teaching practice and possible solutions. For this interpretive, qualitative case study research, two universities were purposively sampled and in each of the universities, three university supervisors and four student teachers were selected. Semi-structured interviews and observations were used as data collection tools. The findings indicated that even though teaching practice is a well-organized programme, challenges were noted. The findings indicated that to a certain degree, teaching practice appears to be fragmented, thus ineffective in assisting student-teachers, and this was evident from the student-teacher’s inability to cope with teaching tasks. Conflicts between teachers and school managers, overcrowded classrooms, misbehaving learners, and unavailability of resources emerged as challenges. The study also reported a gap between theory and practice as student teachers failed to integrate theoretical knowledge with practice. The study recommended a close relationship between teacher training institutions and schools so that when students embark on teaching practice, they can relate to the real complexities of teaching in schools, thus this will bring about the implementation of theory to practical teaching experience.

Experiential Learning in Daylighting Course through Performance Measurements

The main objective of this study is to adapt research studies on performance measurements for daylighting design to education. An experimental course has been introduced in Missouri University of Science and Technology, and the curriculum was developed by including active learning beside the traditional learning environment. The parameters used in the schematic design and design development stages are presented, and the curriculum topics and practical experience are explained in the study. Particularly performance measurements are associated with course assignments. Curriculum results are evaluated qualitatively with assignment results and quantitatively with surveys. Current and emerging metrics are included in lab assignments and results of course assessments show that emerging metrics in daylighting technology and practical experience had attraction over participants. As a result of the evaluation of two sample courses, differences emerge regarding the courses that can be given at undergraduate and graduate levels. These differences are grouped into traditional lecture learning environments and experiential learning environments. The learning outcomes of the course curricula are summarized as gaining the knowledge and skills to communicate technically at the level of design practitioner for the student aiming for undergraduate graduation and at the level of the research community for the student aiming for graduate level.

Examining changes in teacher education programs: A case study approach

This study retrospectively examines teaching practice within Israeli teacher education programs. A pilot study investigates the implementation of a novel teacher education program in Israeli academia, with a focus on the freedom it grants to institutions. This program emerged during the Covid-19 crisis when e-learning dominated. The study assesses 45 respondents' perceptions of teaching practice and the academia-school relationship through a combination of qualitative and quantitative methods. On the quantitative front, the study involved the examination of several questionnaires. These included a self-efficacy questionnaire, an attitude survey regarding teaching, an evaluation of professional identity, and an attitude questionnaire centered on practical experiences within schools. In the assessment of self-efficacy, we utilized a modified version of the General Self-Efficacy Scale (GSE). Additionally, the researchers crafted the other questionnaires. The study also encompassed an exploration of student satisfaction levels concerning collaboration during practical experiences, the acquisition of various skills during school-based practice, and the correlation between the teacher training program's different courses and practical work within school settings. The research covered the documentation and formative assessment of the design and alteration processes within teacher education based on the outlined changes. The study evaluated these processes through primary documents from the academic institution, which provided evidence of the change preparation. It also analyzes the goals, learning outcomes, and teaching methods for students specializing in education. The study highlights changes in teaching practice that foster connections between academia and the field, particularly in pedagogy. These changes focus on the intensified school-based experience, paired with e-teaching workshops. Findings reveal that in evaluating teaching practice competence, interpersonal skills and professional identity rank highly among skills gained during field experiences. The research also showcases the acquisition of essential teaching and class management skills. The study raises questions regarding the program's impact on institutions, particularly concerning its role in enhancing autonomy and relevance. The study evaluates the program’s potential as a catalyst for effective teacher education and its ability to attract mission-driven, motivated individuals to the teaching profession.

Financial indicators utilization among community pharmacists: A comprehensive study for pharmacy management.

The financial management of community pharmacies is a critical aspect of healthcare delivery, as pharmacists often operate as healthcare providers and business managers. Understanding pharmacists' awareness, perceptions, and practices related to financial indicators is essential for effective pharmacy management. There is a paucity of research addressing this issue regionally and locally. This study aimed to investigate the perceptions and utilization of financial indicators among community pharmacists in Jordan and identify demographic and contextual factors influencing their financial practices. A cross-sectional study was conducted, surveying 353 community pharmacists from various regions of Jordan. The developed and validated survey assessed demographic characteristics, utilizations of financial indicators, and perceptions of their significance. Pharmacists were queried about their financial practices, including the use of various financial indicators. Descriptive and analytical statistics were used to portray the study's findings. The study included a diverse group of community pharmacists in terms of demographic characteristics. Most pharmacists exhibited awareness of financial indicators, with a higher awareness of profitability and liquidity indicators. Pharmacists generally had positive perceptions of the importance of these indicators in daily practice. High agreement was observed in financial practices, including following up on payables and receivables, monitoring changes in monthly revenue, and preparing income statements. There was significant variation in the utilization and perception of financial indicators based on factors such as pharmacy ownership, province, foundation age, and practical experience. The findings indicate a positive correlation between utilization and perception, emphasizing the importance of raising awareness of financial indicators among pharmacists. The study also highlights the significance of tailored financial training programs for pharmacists at different stages of their careers and the importance of regional context in financial practices. Understanding these variations can lead to more effective financial management and improved healthcare services in community pharmacies.

A Model for Teaching and Evaluation of Programming Courses in Online mode

To protect community health in the face of the recent spread of COVID-19 epidemic, the world has shifted towards online education. Academics must handle the difficulties presented by the switch from conventional to online learning to preserve the learning process and guarantee that all learning goals are met. One of the key components of engineering education that is significantly impacted using online learning is practical experience. Due to the university's closing and the need for social distance in covid era, students were not able to access physical laboratories. In the present post-covid times, with the rising interest in online courses for skill enhancement and personal growth, institutions and ed-tech companies offering practical courses are finding it difficult to impart programming subjects to students. Another equally important aspect is the choice of right assessment technique for assessing the skill set acquired during the course. This paper proposes a model for conducting lab sessions for practical courses of computer programming, and assessment structure through which coding efficiency of a student can be judged.

“Say It in Broken English”: The Languages of Border Crossing and Hospitality

Drawing on Derrida’s and Ricoeur’s theories of language and hospitality, the author takes up the problem of the hostility embedded in the discourses of welcome when it comes to migrants’ experiences of border regimes and border practices. “Broken English,” in this context, represents a site of conflict: a vehicular language to be avoided or overcome, a “language of refuge,” even a means of forming a community. To explore language as alternative terrain to be policed or an opening to be exploited, the author considers how civil-society art projects involving immigrants and refugees might enable new civic relationships. Focusing on the Shoe Project, a storytelling and performance workshop for immigrant and refugee women, the author asks to what extent the project is about helping the stranger speak like “us” and to what extent it can open space for a different kind of immigration story from those imposed by the legal languages of immigration.

Background/purposeQuantitative in vitro research was conducted on the learning process of a dynamic navigation system. This study provides guidance for the promotion and application of dynamic navigation technology in the endodontic apical surgery field. Materials and methodsStandardized models were designed and 3D printed to form the approach operation of endodontic apical surgery. 6 clinicians with no experience in dynamic navigation performed the operation. The distance deviation tolerance was set as 0.6 mm, and the angle deviation tolerance was set as 5°. Fifteen mm deep approach operation was completed using dynamic navigation. Each operator performed 10 consecutive exercises on the models. The positioning deviation and operation time of each operator for each practice were recorded. Based on this, the learning curve of the dynamic navigation of every operator was mapped. The learning difficulty of dynamic navigation was evaluated. ResultsThe learning curves of all operators reached a stable level after the 7th practice, which can ensure that the distance and angle deviations are maintained within the deviation tolerances (0.6 mm, 5°). ConclusionOperators with no experience in dynamic navigation technology need practice to master dynamic navigation operations. For this navigation system, operators with no operational experience can master dynamic navigation operations after 7 exercises.

The Problems and Difficulties of Medical Devices in Chongqing in Response to Public Health Incidents in 2022

Background and Aim: In the face of emergencies such as large-scale infectious diseases, some medical device manufacturers either do not have enough practical research and development experience in related epidemic prevention medical devices or use cheaper raw materials to reduce product quality in the research and development stage to save costs and increase profits. purpose, and even use various channels and means to bypass market supervision and produce problematic medical devices from the very beginning. Or, to take advantage of the public's panic about unknown infectious diseases, some unscrupulous merchants falsely advertise products that do not meet medical requirements, confusing the masses without certain professional cognitive ability, blindly believing and following them, and causing sudden large-scale infectious diseases. It cannot effectively reduce and contain the spread of diseases or other public health events. Infectious diseases spread rapidly in various cities. This is the problem with the quality supervision of medical devices under public health emergencies. From this new crown pneumonia epidemic, it can be found that the existing system is still unable to meet the needs of emergencies such as public health. It is necessary to do a good job of system reserves for the accessibility of drugs and medical devices from the level of laws and regulations. This needs to be sorted out to achieve accessibility. The existing regulations and systems should be improved to meet the needs of medical device use in public health and other emergencies. Materials and Methods: Safety testing of medical devices used in 26 public health events using Chinese national standards Results: The histogram of sample scores in the operation link reveals a complex landscape with an increased sample size. This data accentuates the intricate scoring dynamics and intricate qualification rates within the operation link, showcasing variations even among identical products from the same manufacturer. The case of "LFR20B" and "LFR30B" infrared forehead thermometers exemplifies how subtle factors, such as the weighting of specific performance indicators, contribute to scoring distinctions. Despite the "LFR20B" model achieving a higher score, it falls short of the category's passing threshold, underscoring the intricate nature of sample evaluations. However, it is noteworthy that 58% of the samples successfully meet national standards and pass the inspection, indicating a substantial portion complying with regulatory requirements. Conclusion: Laws and regulations need to be improved, there are hidden dangers in regulation, the ability of regulatory teams needs to be improved, medical device enterprises have problems, medical devices should strictly follow national standards, and the public should actively participate in medical device regulation.

Inclusive education peculiarities of teachers' perception of a learner with a disability

Introduction. Currently, in the context of the of the education system humanization and with the tendency to increase the proportion of students with disabilities in the total number of children, special attention is paid to creating an inclusive educational environment in basic education institutions. There is a natural increase in requirements for the quality of differentiated educational programs implementation, which is largely determined not only by special professional competences among teachers, but by their individual characteristics as well. In this regard, the issue of accounting for teachers' perception of students with disabilities in the education system is brought out. Aim. The aim of the presented study was to identify the characteristics of the perception of students with disabilities by teachers who have different experiences of interacting with this category of students. Methods of research. The questionnaire survey was attended by 336 teachers. Methods of mathematical statistics: nonparametric criterion Mann–Whitney U-test, correlation coefficient r-Spearman. Statistical calculations were done using a specialized IBM SPSS Statistics 22 program. The results of the study. It is found that the structure of perception of a student with a disability among teachers with diverse experience of interaction with students with disabilities is characterized by a significant number of positive connections between its components. Differences in teachers' attitudes towards students with disabilities (U=121.0; p = 0.003), their emotional attitude (U=120,0; p = 0,000) as well as in the readiness of teachers to implement the educational process (U=118.0; p = 0.000) were revealed. The lack of this experience leads a teacher to the prejudiced assessment of difficulties when organizing and implementing the educational process with the participation of students with disabilities and contributes to the growth of emotional stress in teachers during classes. Scientific novelty. The structure of perception of a learner with a disability by teachers was developed and empirically confirmed on the basis of significant connections of mindsets, attitude and readiness of the teacher. Practical significance. The results of the study will make it possible to develop effective measures of psychological and pedagogical support for teachers in inclusive education, including additional professional programs on inclusive education, accumulation of practical experience of interaction with persons with disabilities in the educational process and everyday life, discussion and elaboration of emotional experiences that arise when interacting with students with a disability.
