How much do library students know about dementia? Findings from a quantitative study using the Alzheimer’s Disease Knowledge Scale
Authors: Faletar Sanjica
Published: April 2024

The goal of the study presented in the paper is to assess the knowledge about Alzheimer’s Disease (AD), among library and information science students in Croatia. Understanding how much future librarians know about dementia is the first step towards providing them with relevant educational intervention which will equip them with required knowledge to develop dementia-friendly library services in a society which is increasingly affected by dementia. A total of 183 students participated in the study which used Alzheimer’s Disease Knowledge Scale (ADKS), a validated instrument that measures what people know about AD using a 30-item questionnaire across seven knowledge domains: risk factors, symptoms, assessment and diagnosis, course of the disease, life impact, treatment, and management, and caregiving. The collected data were analysed using basic descriptive statistics and a parametric test (t-test). Findings show that respondents have poor AD knowledge. Only 35.78% questions were answered correctly and the mean knowledge score was 10.76. The findings revealed that participants with previous exposure to the disease have significantly better knowledge (P= 0.003).

Authors: Wan Xinjie , Pu Hao , Schonfeld Paul , Song Taoran , Li Wei , Peng Lihui
Published: April 2024

Railway alignment development in a study area with densely-distributed obstacles, in which regions favorable for alignments are isolated (termed an isolated island effect, i.e., IIE), is a computation-intensive and time-consuming task. To enhance search efficiency and solution quality, an environmental suitability analysis is conducted to identify alignment-favorable regions (AFRs), focusing the subsequent alignment search on these areas. Firstly, a density-based clustering algorithm (DBSCAN) and a specific criterion are customized to distinguish AFR distribution patterns: continuously-distributed AFRs, obstructed effects, and IIEs. Secondly, a study area characterized by IIEs is represented with a semantic topological map (STM), integrating between-island and within-island paths. Specifically, between-island paths are derived through a multi-directional scanning strategy, while within-island paths are optimized using a Floyd-Warshall algorithm. To this end, the intricate alignment optimization problem is simplified into a shortest path problem, tackled with conventional shortest path algorithms (of which Dijkstra’s algorithm is adopted in this work). Lastly, the proposed method is applied to a real case in a mountainous region with karst landforms. Numerical results indicate its superior performance in both construction costs and environmental suitability compared to human designers and a prior alignment optimization method.
An improved subdomain modeling technique for surface-mounted permanent magnet Vernier motor
Authors: Bao Guangqing , Chang Yong , Zhang Anan
Published: April 2024

This work aims to provide a unique analytical model designed for calculating the magnetic field of a surface-mounted permanent magnet Vernier motor (SPMVM). The model is created utilizing the separation variable method to solve Laplace or Poisson equations of the vector magnetic potential in a quasi-Cartesian coordinate system subdomain model. The theoretical justifications for the final analytical equations of electromagnetic torque, no-load back-EMF, stator inductance, and magnetic flux density distribution are given in detail. Then the solution of the equation is expressed in the form of a hyperbolic function. Furthermore, the improved analytical method in the study is generic and can be applied to estimating the parameters of machines with different design concepts. Finally, FEM is employed as the reference for comparison between other models. Compared to the original subdomain model, the calculation results of the improved analytical model are more time-efficient and closer to those of FEM. In addition, the improved analytical method can reduce the dimension of the coefficient matrix and improve the calculation speed. The SPMVM prototype is then built to demonstrate the validity and feasibility of the improved subdomain method and serves as a guide for future SPMVM development.

Published: April 2024

Word embeddings have been successfully used in diverse tasks of Natural Language Processing, including sentiment analysis and emotion classification, even though these embeddings do not contain any emotional or sentimental information. This article proposes a method to refine pre-trained embeddings with emotional and sentimental content. To this end, a Multi-output Neural Network is proposed to learn emotions and sentiments simultaneously. The resulting embeddings are tested in emotion classification and sentiment analysis tasks, showing an improvement compared with the pre-trained vectors and other proposes in the state-of-the-art for fine-grained emotion classification.
Deep fine-tuned efficientNetV2 ensemble deep learning approach for pediatric pneumonia detection using chest radiographs
Authors: Ravi Vinayakumar
Published: April 2024

Deep learning-based models are employed in computer-aided diagnosis (CAD) tools development for pediatric pneumonia (P-Pneumonia) detection. The accuracy of the model depends on the scaling of the deep learning model. A survey on deep learning shows that models with a greater number of layers achieve better performances for P-Pneumonia detection. However, the identification of the optimal models is considered to be important work for P-Pneumonia detection. This work presents a hybrid deep learning model for P-Pneumonia detection. The model leverages the EfficientNetV2 model that employs various advanced methodologies to maintain the balance between the model scaling and the performance of the model in P-Pneumonia detection. The features of EfficientNetV2 models are passed into global weighted average pooling (GWAP) which acts like an attention layer. It helps to extract the important features that point to the infected regions of the radiography image and discard all the unimportant information. The features from GWAP are high in dimension and using kernel-based principal component analysis (K-PCA), the features were reduced. Next, the reduced features are combined together and passed into a stacked classifier. The stacked classifier is a two-stage approach in which the first stage employs a support vector machine (SVM) and random forest tree (RFT) for the prediction of P-Pneumonia using the fused features and logistic regression (LRegr) on values of prediction for classification. Detailed experiments were done for the proposed method in P-Pneumonia detection using publically available benchmark datasets. Various settings in the experimental analysis are done to identify the best model. The proposed model outperformed the other methods by improving the accuracy by 4% in P-Pneumonia detection. To show that the proposed model is robust, the model performances were shown on the completely unseen dataset of P-Pneumonia. The hybrid deep learning-based P-Pneumonia model showed good performance on completely unseen data samples of P-Pneumonia patients. The generalization of the proposed P-Pneumonia model is studied by evaluating the model on similar lung diseases such as COVID-19 (CV-19) and Tuberculosis (TBS). In all the experiments, the P-Pneumonia model has shown good performances on similar lung diseases. This indicates that the model is robust and generalizable on data samples of different patients with similar lung diseases. The P-Pneumonia models can be used in healthcare and clinical environments to assist doctors and healthcare professionals in improving the detection rate of P-Pneumonia.

ComMatch: A semi-supervised learning classification algorithm based on model calibration
Authors: Li Ye , Zhou Jingkang
Published: April 2024

Semi-supervised learning (SSL) aims to reduce reliance on labeled data. Achieving high performance often requires more complex algorithms, therefore, generic SSL algorithms are less effective when it comes to image classification tasks. In this study, we propose ComMatch, a simpler and more effective algorithm that combines negative learning, dynamic thresholding, and predictive stability discriminations into the consistency regularization approach. The introduction of negative learning is to help facilitate training by selecting negative pseudo-labels during stages when the network has low confidence. And ComMatch filters positive and negative pseudo-labels more accurately as training progresses by dynamic thresholds. Since high confidence does not always mean high accuracy due to network calibration issues, we also introduce network predictive stability, which filters out samples by comparing the standard deviation of the network output with a set threshold, thus largely reducing the influence of noise in the training process. ComMatch significantly outperforms existing algorithms over several datasets, especially when there is less labeled data available. For example, ComMatch achieves 1.82% and 3.6% error rate reduction over FlexMatch and FixMatch on CIFAR-10 with 40 labels respectively. And with 4000 labeled samples, ComMatch achieves 0.54% and 2.65% lower error rates than FixMatch and MixMatch, respectively.
Cultural cimension of Hryhorii Skovoroda's philosophy
Authors: Fedorenko Mykola
Published: April 2024

The purpose of the work is to study the cultural foundations of Hryhorii Skovoroda's philosophy. The research methodology is based on the use of commonly used approaches of analysis, synthesis, and comparison. The study is based on an understanding of the importance of the cultural context of the phenomenon of intellectual history. Scientific novelty. The author argues the thesis about the decisive role of the Ukrainian Baroque in the formation of Ukrainian identity. The author argues that the birth and maturation of authentic spiritual and academic culture is linked to European historical sources. The basic principles of the Cossack Baroque and their manifestation in the creative heritage of Hryhorii Skovoroda are substantiated. Conclusions. The origins and features of Baroque culture are analysed. The attention is focused on the Baroque's desire for universality, the attempt to comprehend infinity, and the attraction to dynamism. The significance of contrasts and antitheses in Baroque culture as a means of reproducing the dynamics of life is emphasised. The phenomenon of the emblem as a means by which things of the external world are introduced into human life and acquire cultural functions is investigated. It is noted that the Baroque is a time of practical action, realisation of energy, and the search for new forms by a person of this era. It is pointed out that Skovoroda develops an understanding of the contemplative attitude as a practical action that requires not passivity, but an active attitude. The tendency of the Western European Baroque to a mystical, eschatological experience of the world is pointed out. The thesis of the optimistic significance of the Baroque style in Eastern Europe is demonstrated. The author shows the connection between Ukraine's contribution to Baroque culture and Hryhorii Skovoroda's philosophical rethinking of the pessimistic manifestations of the modern era.

Scientific novelty. The reception of foreign cultural practices in the modern urban space was studied as a subject of cultural research; clarification of the concept of "reception" and "foreign cultural practices"; on the basis of the analysis of theoretical developments on the issues of dialogue of cultures, perception of the work and reception aesthetics, promising approaches to the study of the specified issues have been identified. Conclusions. Foreign cultural practices presented in the modern urban space of Ukraine is a complex phenomenon, the study of which is a prism for identifying the national cultural strategy. Based on the understanding of cultural reception as the perception, assimilation, understanding and further development within the limits of one's own culture of a certain phenomenon borrowed from another culture and the peculiarities of the response of a person or a group of people to a certain cultural phenomenon, it is possible to state the feasibility of researching the reception of foreign cultural practices in the context of transfer (of concepts, ideas , methods of cultural practices or their elements) from the donor culture, their adaptation and integration into the modern urban space of Ukraine (the main mechanisms of reception of foreign cultural practices - "transformation" and "reproduction") and reception of foreign cultural practices by the recipient (spectator, listener, participant). A promising direction of research is addressing the personality by means of applying the receptive approach of a key figure of a specific foreign cultural practice, which contributed to its formation, development and popularization. At the same time, this approach can contribute to the identification of characteristic features of foreign cultural practices and a number of features of their multifaceted receptions.

Among the notable features, the author notes the balance found between the demonstration of artworks of recognised masters of the modernist era and representatives of the regional art centre. The inclusion in the main exposition of a number of paintings by the local symbolist artist Mykhailo Sapozhnykov contributed to a certain extent to the integration of his figure and creative work into the line of Ukrainian fine art development in the first third of the 20th century.
Image of Roma people in genre realistic painting of the 19th – early 20th centuries: stylistic and narrative peculiarities
Authors: Rohotchenko Oleksii
Published: April 2024

The purpose of the research is to analyze the stylistic and narrative peculiarities of the works of genre realistic painting dedicated to Roma images of the 19th – early 20th centuries. Research methodology. To achieve this purpose, the comparative historical method and art historical analysis were used. The scientific novelty of the study is justified by its purpose: the study is the first attempt in the national art history to analyze works of some European realist artists of the 19th – early 20th centuries on the Roma theme represented in the works of narrative genre. This theme has not been actually studied, although it eloquently represents the growing interest in the subjective depiction of a wide-range life of various social strata and ethnic communities in the European countries and is one that influenced the formation of more positive attitude towards Roma people in the 19th – early 20th centuries, who were oppressed by the policies of national European states. Conclusions. The article analyzes some artistic works of Thomas Baker, August von Pettenkofen, Alfred Munnings as typical representatives of realistic painting in Europe of the 19th – early 20th centuries, whose creative heritage contains some storylines dedicated to Roma images in the context of socio-economic, spiritual and cultural aspects of Roma existence. It is emphasized that these artists, as leaders of public opinion, who were not indifferent to a difficult situation of Roma communities, improved the attitude of society thereto in this period. Two ideological and narrative trends have been described. The first describes difficult social and material situation, and the second focuses on creating an areola of romance around the life of Roma communities. Thus, it is established that the works of European artists not only drew attention to social and domestic problems of the Roma ethnic group, but also are typical examples of realistic painting of that period.

Authors: Boyko Vyacheslav
Published: April 2024

The purpose of the article is to analyse the Roma theme in the landscape painting in the works of artists-realists of the second half of the XIXth century. The research highlights the motives, related to the traditions of the Roma, which attracted the realistic direction artists’ attention. It is reviewed that the majority of Roma images and their traditional life style of the second half of the 19th century were presented in the painting works with the introduction of the landscape storylines. The research methodology includes the following methods: historical-cultural method and analytical one, a method of the historical-artistic typology and logical-generalizing method. These methods made it possible to follow the development of Romani subjects in the landscape art of the studied period. The scientific novelty of the article is an attempt to fill up the lack of research on the chosen topic and the need to introduce it into the scientific circulation as such, which will make the Roma topic in the context of realistic landscape painting in the world fine art of the XIXth century interesting for the researchers, historians etc. Conclusions. The research consists of the several stages. The first one is the analysis of the historiographical base, which has allowed to emphasize the relevance of studying the dialogue of the landscape and Roma images in the works of realist artists. During the second research stage, the peculiarities of the landscape genre in the realism direction works are characterized. In addition, the canvases of August von Pettenkofen (1854), Kharyton Platonov (1877), David Bates' (1886) and Franciszek Streitt (1885–1886) were singled out from the array of the artistic works and described in the context of the interdependence of the landscape and Roma images and (or) scenes from Roma life. Finally, it is shown that the landscape does not contrast with the Roma theme in these works, moreover it is a tool for its highlighting. Therefore, it is logical to conclude that the landscape line was used by realist artists as a logical component of the romance of nomadism in the XIXth century.

Authors: Paliichuk Iryna , Du Bohao
Published: April 2024

The purpose of the proposed article is to highlight the genre and style dynamics of the saxophone quartet in the world musical culture of the 19th and 20th centuries. The research methodology is based on the use of the following methods: historical – when outlining the genesis and evolution of the saxophone quartet genre; analytical and typological – when identifying the immanent features of specific works of the analysed genre and combining them into appropriate typological groups; general cultural – when reproducing the historical and stylistic context of the development of the genre (in the unity of compositional and performing components). The scientific novelty of the work consists in a panoramic study of the evolutionary process of the saxophone quartet genre in the world musical culture of the 19th-20th centuries, outlining its periodization, and determining the genre-stylistic features of individual works of the analyzed genre. Conclusions. In the process of researching the evolution of the saxophone quartet genre in the world musical culture of the 19th and 20th centuries, its periodisation is proposed: the second half of the 19th century – forming a saxophone quartet; the first half of the 20th century – crystallisation, establishment of immanent features of the genre; the second half of the 20th century – the beginning of the 21st century – modification of the saxophone quartet genre – enrichment of its genre-stylistic features, typological types. On the basis of the analytical characteristics of individual saxophone quartets, it was concluded that the analysed genre reflects the leading stylistic trends in the development of European, and more broadly, world musical culture, such as the tendency towards programming (G. Bumke, J. France, J. Absil), neoclassicism (E. Bozza), the use of pointillistic technique and dodecaphony (A. Webern), the combination of modern musical language with jazz stylistics (A. Desenclo), minimalism and jazz (F. Glass).

Authors: Stakhevych Oleksandr
Published: April 2024

The purpose of the article is to highlight the vocal-romance creativity of the outstanding Ukrainian composer of the first half of the 20th century Mykhailo Skorulskyi in the context of genre-style transformations and artistic challenges of the time. The methodological basis. A complex of scientific (theoretical and practical) methods is used to reveal the topic. To find out certain stages and features of the development of the romance genre in the work of M. Skorulskyi, biographical, historical-cultural and interdisciplinary methods were used. Providing a historically objective assessment of the composer’s chamber-vocal legacy became possible thanks to historical-comparative, systematic, axiological research methods. Establishing the specificity of the artist’s romance work was carried out with the help of music-theoretical analysis. Scientific novelty of the article. For the first time in Ukrainian musicology, the stylistic evolution of chamber-vocal genres in Ukrainian music of the first half of the 20th century was considered, using the example of Mykhailo Skorulskyi’s vocal-romance work. The stages are highlighted, the emotional and figurative sphere of the artist’s romance works is highlighted. Conclusions of the work. The stylistic transformations of M. Skorulskyi’s work as a composer in the genre of romance were determined both by the “internal” needs of the artist regarding the content, emotional content and figurative structure of the works, and by “external” – the influence of socio-political circumstances and ideological requirements of the Soviet culture of the 1920s and 1930s. The compositional evolution of M. Skorulskyi’s romance work reflects all stages of the development of the genre during the first half of the 20th century: from the subjectivist lyrics of the beginning of the century, through the heroic-revolutionary motifs of the 1920s and early 1930s, to nostalgic feelings and patriotic sentiments during the Second World War.

Published: April 2024

In the pursuit of precise forecasts in machine learning-based breast cancer categorization, a plethora of algorithms and optimizers have been explored. Convolutional Neural Networks (CNNs) have emerged as a prominent choice, excelling in discerning hierarchical representations in image data. This attribute renders them apt for tasks such as detecting malignant lesions in mammograms. Furthermore, the adaptability of CNN architectures enables customization tailored to specific datasets and objectives, enhancing early detection and treatment strategies. Despite the efficacy of screening mammography, the persistence of false positives and negatives poses challenges. Computer-Aided Design (CAD) software has shown promise, albeit early systems exhibited limited improvements. Recent strides in deep learning offer optimism for heightened accuracy, with studies demonstrating comparable performance to radiologists. Nonetheless, the detection of sub-clinical cancer remains arduous, primarily due to small tumor sizes. The amalgamation of fully annotated datasets with larger ones lacking Region of Interest (ROI) annotations is pivotal for training robust deep learning models. This review delves into recent high-throughput analyses of breast cancers, elucidating their implications for refining classification methodologies through deep learning. Furthermore, this research facilitates the prediction of whether cancer is benign or malignant, fostering advancements in diagnostic accuracy and patient care.

In particular, the influence of European integration processes on the terms of foreign trade and export activities of agricultural enterprises is considered. The article also highlights the aspects of the formation of export potential in the context of European integration. Today, the agro-industrial complex is one of the largest and most important sectors of the Ukrainian economy. It is here that the bulk of food resources and almost three-quarters of retail turnover are formed. In addition, agro-industrial enterprises have a significant contribution to the development of the industry and the country's economy as a whole. The agricultural sector of Ukraine is also one of the key elements of the economic systems of many countries with market economies. The development of the export potential of agricultural products is a guarantee of economic growth as a whole, which includes, among other things, staff training and qualitative changes in the marketing system. The prospects for the successful formation of the export potential of agricultural enterprises of Ukraine in the conditions of European integration are that agricultural enterprises should focus on improving the quality of their products and compliance with international standards. This will allow them to take their place in international markets and compete with other countries. In addition, increasing the range of products will allow agricultural enterprises to optimize their competitiveness on foreign markets and reduce the risk of changes in export conditions. Improvement of transport links, customs procedures and storage conditions will ensure efficient and quick export of agricultural products.

Published: April 2024

Розглянуто масштаби, чинники, проблеми недекларування зайнятості та праці в Україні; визначено пріоритети та заходи її регулювання (відстеження, пом’якшення, запобігання). Недекларування зайнятості та праці, що виникає та функціонує в межах як унормованих (офіційних, маніпулятивних), так і тіньових механізмів, відіграє помітну роль у практиках пожвавлення підприємницької активності, підвищення конкурентоспроможності суб’єктів господарювання в індустріальних, нео- та постіндустріальних економіках. Пріоритети регулювання незадекларованої зайнятості та праці в Україні передусім охоплюють: послідовне зростання частки оплати праці в структурі витрат виробництва; посилення перехресного контролю за виконанням гарантій мінімальної оплати праці в рамках відповідних погодинних і безтарифних систем; впровадження обґрунтованої методології і стратегії узгодження мінімальної оплати праці, прожиткового мінімуму, решти пов’язаних з ними основних соціальних стандартів.

У статті проаналізовано поняття імітаційного моделювання та імітаційної моделі. З розвитком автоматизованих систем управління та збільшенням областей використання обчислювальної техніки постає більше різноманітних економічних і управлінських завдань, які потребують вирішення. Розробка адекватних моделей для цих завдань і розробка ефективних методів їх вирішення стають актуальними проблемами. Це особливо стосується завдань, що включають фактори невизначеності, динамічну взаємну залежність поточних рішень, подальших подій та складну взаємозалежність між факторами. Наголошено на тому, що імітаційне моделювання представляє собою метод проведення експериментів з використанням математичних моделей на електронно-обчислювальних машинах (ЕОМ). Його основна мета полягає в відтворенні поведінки складних систем протягом тривалих періодів часу. Цей підхід базується на використанні властивостей наслідування, дозволяючи відтворювати процеси у досліджуваних системах за допомогою математичних моделей на ЕОМ.

Published: April 2024

У статті здійснено аналіз діяльності Українського фонду стартапів (УФС) як ключової державної інституції розвитку стартап-екосистеми нашої держави. Продемонстровано його інструменти підтримки інноваційних проектів, починаючи з моменту виникнення, а саме: з 2018 року. Зазначено, що УФС був створений з метою допомагати інноваційним проектам та технологічним стартапам залучити кошти на ранніх етапах та запустити власні проекти. З першого року діяльності УФС фінансувалися інноваційні проекти в різних секторах та галузях, за винятком лише виробництва тютюнових та алкогольних продуктів, а також грального бізнесу, воєнних та ядерних технологій. Зроблено акцент: у фокусі уваги фонду – стартап-проекти на ранніх стадіях розвитку seed та pre-seed. Зазначено, що сферами зацікавленості УФС з 2019 року до початку повномасштабної війни були: штучний інтелект, доповнена реальність, аналітика великих даних, блокчейн, кібербезпека, оборонні технології, медицина та охорона здоров’я, подорожі, фінансові технології, освітні платформи, роботи, професійні послуги, програмне забезпечення як сервіс, виробництво, електронна комерція, інтернет-речі. У дослідженні продемонстровано: з початком активних воєнних дій у 2022 році УФС перемкнувся на підтримку проектів у сферах defense tech та deep tech (оборонні технології та глибокі технології). В умовах війни фонд сфокусувався на просуванні проектів із подвійним призначенням грантами до 35 000 дол. та програмах інноваційних ваучерів. У дослідженні наголошено, що з моменту, коли 27 грудня 2022 року Український фонд стартапів перейшов з-під юрисдикції Міністерства фінансів до складу Міністерства цифрової трансформації України, на нього покладені завдання систематично втілювати ідеї та сприяти розвитку стартапів у сфері military-tech (військові технології). У статті здійснено огляд основних інструментів підтримки УФС станом на березень 2024 року, а саме: грантова підтримка, «FastTrack до перемоги», «інноваційні ваучери», «корпоративні інновації», «Seeds of Bravery». Підсумовано, що з 2019 року УФС відіграє ключову роль у розвитку стартап-екосистеми України, фінансуючи та розвиваючи новаторські проекти, представляючи українські проекти на міжнародному рівні та залучаючи міжнародні інвестиції, а також розвиваючи партнерство з провідними корпораціями; його програми сприяють створенню технологічного ландшафту в Україні, підвищуючи конкурентоспроможність та інноваційний потенціал країни.
