Atypical delayed ventriculoperitoneal shunt infection following hysteroscopic polypectomy: illustrative case
Authors: Bialek Shannan , Stevens Baylee , Tavakol Sherwin A. , Alkozah Maria , Graffeo Christopher S.
Published: November 2024

BACKGROUND

A 36-year-old female with a history of congenital hydrocephalus, treated with ventriculoperitoneal (VP) shunt placement at 3 months of age and a shunt revision at 9 years of age, presented with erythema, induration, and drainage of an abdominal incision through which the distal catheter of her VP shunt had been implanted many years prior. She had no recent risk factors for infection apart from a minor transvaginal gynecological procedure that involved hysteroscopy with dilation and curettage for uterine polyps.

OBSERVATIONS

Abdominal wound cultures grew Cutibacterium acnes, Corynebacterium species, and Mycobacterium chelonae. She was managed with initial externalization, followed by complete explantation of her shunt system following a successful clamp trial; in tandem, the atypical polymicrobial infection was treated with a prolonged regimen of intravenous antibiotics followed by oral antibiotics and close monitoring of the wound, which healed appropriately.

LESSONS

Although the majority of shunt infections occur due to a characteristic set of organisms within an expected time frame, this case emphasizes the importance of a thorough workup and follow-up for shunt-treated patients with potential infections—even when they fall outside the usual window or have an atypical presentation—for the possibility of uncommon infecting organisms.

Penetrating intracranial injury from a pencil in a pediatric patient: illustrative case
Authors: Liu Eva , Su Hsuan Ming , Toyota Patrick , Newton Braeden D. , Coote Nicole , Marciniuk Kristen , Ahmed Syed Uzair , Kelly Michael E. , Peeling Lissa
Published: November 2024

BACKGROUND

Intracranial penetrating injuries from a pencil are exceptionally rare. The most common mechanism is a child running while holding a pencil. Potential consequences of intracranial pencil injury include direct trauma to brain structures, vascular injury, and intracranial abscess formation.

OBSERVATIONS

A 3-year-old girl was at daycare and had fallen while running with a pencil. Computed tomography showed a pencil penetrating the left parietal bone through the left temporal lobe, terminating in the posterior limb of the internal capsule. Cerebral angiography was performed prior to the removal of the pencil to rule out vascular injury. Angiography of the left carotid artery revealed slight irregularity in the left M2 but no active extravasation. The patient was then taken to the operating room to have the pencil removed. Postoperatively, she did well and was discharged home after 6 days with no neurological deficits.

LESSONS

Pencils are rare causes of intracranial injury in children. Definitive vascular imaging prior to pencil removal to rule out vascular injury and minimize the risk of hemorrhage after removal is recommended. Intraoperative irrigation and debridement, followed by antibiotics, are recommended to avoid abscess formation. Follow-up vascular imaging is recommended to rule out pseudoaneurysm.

Long-term survival in a patient with Li-Fraumeni syndrome–associated giant cell glioblastoma treated with nivolumab: illustrative case
Authors: Mitchell Macy , Restrepo-Orozco Andres , Verhey Leonard H. , Vitaz Todd
Published: November 2024

BACKGROUND

Li-Fraumeni syndrome (LFS) is characterized by p53 germline mutations and a high predisposition to cancers including glioblastoma (GBM), the most common and aggressive primary malignant brain tumor in adults. Despite current therapies, the 5-year survival rate is 5%–10%. The authors report a case with a durable long-term response to immunotherapy with checkpoint inhibition in a patient with LFS-associated GBM.

OBSERVATIONS

An 18-year-old female presented after a syncopal episode and left leg weakness and was found to have a right frontal tumor. She underwent gross-total resection of the tumor (grade IV giant cell GBM IDH-wildtype, MGMT unmethylated, associated with a p53 germline mutation), radiation, and chemotherapy. On later imaging, increased enhancement was demonstrated, which raised concerns for tumor recurrence, and she underwent stereotactic radiosurgery followed by lomustine and procarbazine. These agents were later replaced with bevacizumab after a second resection, negative for recurrent glioma. Subsequently, nivolumab was added, given concerns for tumor progression, and the patient showed improvement within 5 months. The patient has continued nivolumab monotherapy and has had progression-free survival for more than 7 years.

LESSONS

Despite advances in treatment, the median survival of patients with GBM is only 15 months. This case highlights the potential of immunotherapy with PD-L1 checkpoint inhibition in improving outcomes for LFS–associated GBM patients.

ENHANCING ANTICORROSIVE PROPERTY OF MILD STEEL COATED BY SYNTHESIZED EUGENOL-BASED BENZOXAZINE WITH 3-ACETYL PHENYL SIDE CHAIN AND COPOLYMERIZING WITH URETHANE
Authors: S. Elavarasan  , N. Vijayakumari  , D. Anbuselvi
Published: November 2024

The reaction of paraformaldehyde, 3-amino acetophenone, and eugenol yields EuBz-based Benzoxazine monomer (EuBz-ap), which is then characterized by FT-IR,1H NMR, and UV-visible spectroscopic techniques. The produced monomer is then cured by applying it to mild steel (MS) using a polyurethane (PU) hardener. Furthermore, investigations using electrochemical polarization examine the impact of varying PU hardener concentrations on mild steel coated with EuBz-ap-PU and combined with benzoxazine monomer on gel and water absorption. The findings show that the coating's anticorrosive qualities are improved with increased PU concentrations. Moreover, Density Functional Theory (DFT) computations are employed to validate the corrosion resistance of the material.
Simulation of a Potential Sector Collapse on the Koryaksky Volcano and Volcanic Hazard Assessment for the Yelizovo-Petropavlovsk Agglomeration (Kamchatka)
Authors: Dolgaya A. A. , Bergal-Kuvikas O. V.
Published: November 2024

Based on the modeling of a potential sector collapse on the Koryaksky volcano, the most probable direction of movement of a debris avalanche is shown. Periodic fumarole activity of the volcano indicates the circulation of meteoric waters and favorable conditions for the replacement of the volcano bedrock with the development of landslide deposits. On the basis of satellite data, deformations of the earth's surface have been studied. The northeastern slopes of Koryaksky volcano rise relative to the descending southwestern slopes. Taking into account the fact that Avachinsky volcano, which is located 10 km from the Koryaksky volcano, has formed powerful landslide-explosive deposits in the history of its development, the relevance of this study is extremely high. Within the Yelizovo-Petropavlovsk agglomeration (which includes the cities of Yelizovo, Petropavlovsk-Kamchatsky and the adjacent settlements of the Yelizovsky district), which is located in the immediate vicinity of the Koryaksky volcano, more than half of the total population of the Kamchatka region lives and there are enterprises that bring more than half of all financial profit of the region. Therefore, the assessment of hazardous natural processes on the Koryaksky volcano in order to further develop a plan to minimize their negative consequences is critical for the economy of Kamchatka.
Religious Inflection in the Economy of Experience: The Concept of Atmosphere in Aesthetic and Phenomenological Thought of Hermann Schmitz and Gernot Böhme
Authors: Runkel Simon
Published: November 2024

The article offers a brief genealogy of the concept of atmosphere in the thought of Hermann Schmitz (New Phenomenology) and Gernot Böhme (Aesthetic Theory) to show that the concept takes on a quasi-religious appearance, especially in its design and economic applications. It is shown how a phenomenological concept of religious origin could become a pseudo-psychological marketing strategy. The article argues that the concept of atmosphere should not be applied too exclusively to the design of (interior) spaces, but that the sociality of atmospheres should also be taken into account. In this way, attention can be drawn to the manipulative power of the atmospheric.
The Origin and Affinities of the Tagar People: A View from Half a Century Later
Authors: Kozintsev Alexander G.
Published: November 2024

To revise the origins and external relationships of the Tagar population (800–300 BC) nearly half a century after my book (1977), 36 male Tagar cranial samples were compared with 117 samples representing other periods and regions using multivariate statistical methods. To date, the principal contenders for the role of Tagar ancestors are the Andronovans, whose key role is supported by genetic facts. The pre-Andronovo substratum was likely represented by the Chaa-Khol’ people of Tuva and the Yelunino people of the Upper Ob. The Karasuk tribes do not appear to have taken part in Tagar origins. Among the neighbors of the Tagar people, the closest to them are the Pazyryk people of the Ursul, Altai, and certain Sagly people of Aimyrlyg, Tuva. Judging by the dates, those groups resulted from a southward migration of certain Tagar populations at the Saragash stage. Since the Chaa-Khol’ people, as I showed previously, were extremely close to Scythians of the steppes, and among the Tagar people, to those of the Saragash stage, it appears that the Saragash people or their descendants had migrated not merely to the Altai-Sayan region but also much further west – to the Eastern European steppes. The archaic Scythian culture, which preceded this migration, may have spread along the same route, but by way of diffusion.
The Ciboney and the Taino in the Context of Craniometric Variation in Native American Population
Authors: Syutkina Taisiya A.
Published: November 2024

The article examines two cranial samples representing the pre-Columbian population of Cuba (the Ciboney and the Taino), in the general context of craniometric variation in the indigenous population of the American continent. Published craniometric data from various sources were used for comparison by the canonical discriminant analysis and calculation of pairwise squared Mahalanobis distances. The question is raised about the possibility of including artificially deformed crania (of which the Taino and many other American samples are entirely composed) in the analyses using only the metrics of the facial skeleton. When analyzing samples without artificial deformation, similarities were found between the Ciboney and South American groups, mainly from the West, which may indicate their origin from an ancient and less differentiated type that inhabited Central and northwestern South America in ancient times. The results of the analysis combining deformed and non-deformed samples are more difficult to interpret, which may indicate a significant influence of cranial vault deformation on the morphology of the facial skeleton, but they do not contradict the conclusions of studies of related sciences about the South American origin of the Taino.
Spatial Modeling of the Folk Astronomical Knowledge among the Residents of Tajikistan
Authors: Dubova Nadezhda A. , Nikiforov Michail G.
Published: November 2024

The term “folk astronomical knowledge” refers to a set of practical knowledge that allows a person to navigate in space and time. An important point is the possibility of a total assessment of this knowledge not only at the level of an individual, but also at the level of a separate settlement or region. The authors developed a method for determining an indicator characterizing the level of folk astronomical knowledge, based on field materials collected in the Republic of Tajikistan in 2019–2023. The method was verified on a large sample (177 people were surveyed). The average values of the “coefficient of knowledge” (k) made it possible to assess the process of knowledge loss among informants of four age groups, as well as to compile maps reflecting the preservation of folk astronomical knowledge in the studied territories. The analysis of the maps makes it possible to propose a model describing the observed prevalence of this knowledge. Its maximum level is recorded along the Pamir Tract, in the zone of active information exchange, and the minimum is in isolated valleys. Based on the proposed model, high-quality predictions were made about the level of popular astronomical knowledge in areas that have not yet been surveyed.
Religious Identity in the Context of Present-Day Ritual Culture of the Kyrgyz People
Authors: Kochkunov Aidarbek S.
Published: November 2024

The article examines the ethnographic aspects of the religious identity of the Kyrgyz people, expressed through attitudes to the rituals of the family cycle, mainly funeral and memorial rites. The article describes the features of the development of religious culture, regional differences in the manifestation of religious identity, the place of ritual in the discourse between traditionalism and Islamic normativity, and issues of regulating rituals. The uniqueness of the history of the religious life of the Kyrgyz people is noted, which lies in repeated modernization during the 20th century: the transition from total atheization to the revival of religious consciousness. The diversity and inconsistency of religious identities, the nature of the clash of positions between different trends on the values of the folk ritual of the family cycle are studied. It defines that today the rituals of the folk have become the central issue of the discourse between traditionalists, Islamic normativists, “statists” and representatives of secular approaches. The author comes to the conclusion that the regulation of some aspects of rituals, in particular funeral and memorial rituals, shows a tendency towards convergence of state and religious (Islamic) approaches, which in the future may lead to contradictions between different identities.
Modern Cinderellas: The Specifics of Marriage Strategies for Women with Disabilities
Authors: Nosenko-Stein Elena E. , Savin Igor S.
Published: November 2024

The article examines life strategies of disabled women who wish to find a spouse/life partner and build a family. We take the cases of contemporary Russia and Kazakhstan as countries that in many aspects share a common post-Soviet social and cultural background. Israel, which is considered one of the countries favorable for disabled people, is additionally taken as a case for comparison, for in fact there live many impaired ex-Soviets including women with disabilities. Drawing on own field research, we attempt to outline the principal models of marital behavior of such women in the countries under examination, pinpointing their specificities in each case. We argue that despite different social and cultural surroundings as well as varying ethnic and religious traditions, the factor of double stigmatization – both of disability and of gender stigmatization – makes a profound impact on self-identifications of these women who feel more vulnerable if compared with so-called “normal” women.
Images of Industrial Cities of Tatarstan in the Vision of the Leaders of Urban Communities and Ordinary Residents
Authors: Makarova Guzel I.
Published: November 2024

The article examines the verbally recorded dominants of the vision and construction of images of non-capital industrial cities of Tatarstan by their leading actors, accepted and described in their own way by ordinary citizens. They are supplemented by the author’s personal observations and analysis of the meanings embedded in urban symbols and toponymy, monumental propaganda and works of art. Conducted in 2021–2022 in Naberezhnye Chelny, Nizhnekamsk, Almetyevsk, and Zelenodolsk, expert interviews and problem-oriented interviews with families showed that their industrial specialization (and, accordingly, the designation as a city of mechanical engineers, chemists, oil workers, shipbuilders), as well as the associated features of the mentality of the residents, continued to determine their images. Moreover, the plant becomes a kind of invisible “partner” for every city dweller, setting the rhythm and style of life, key moments of historical memory. At the same time, the individuality of settlements is influenced by the peculiarities of the formation of their population, sociocultural spaces and urban culture, including ethnocultural specifics.
Sustainable Fashion: Definitions and Their Interpretation in the Ukrainian Scientific Discourse
Authors: Soloviy Iryna
Published: November 2024

The aim of the article is to analyse and systematise existing definitions and translation options for the sustainable fashion term in the Ukrainian language; to outline the difference of this term with the concept of “ecological fashion” taking into account their tendencies to evolve, as well as to clear up definite terms. Research methods: the method of comparative analysis of scientific publications in the fashion sphere, as well as methods of synthesis and generalisation are applied. Scientific novelty: the existing definitions and translations of sustainable fashion in the Ukrainian scientific discourse are analysed and systematised, and the tendencies of their usage with a certain semantic load are traced. The definitions of sustainability in fashion design in the publications of Ukrainian scientists are presented in the table. The practical significance of the work grounds in the possibility of using the results of the study for rethinking and forming a holistic system of ideas about the concept of sustainability in fashion of Ukraine, where each component is an important part of achieving the goal. Conclusions. At the moment, the study proves that a set expression “sustainable fashion”, taking into account the concept of “sustainable development”, can be considered as the most appropriate translation of the term sustainable fashion, which is a significant basis for this translation. Understanding the concept of sustainability in fashion of Ukraine, a deep understanding of its principles and mechanisms of action emphasises the designer’s activity and stakeholders on the use of conscious and thoughtful processes, technologies, materials. In addition, as a result of the analysis, it can be concluded that it is important to translate and adapt the English-language terminology from the fashion design design for use in Ukraine, which actualises the awareness and understanding of multiple processes that influence the formation of approaches to fashion based on the principles of sustainability.
The Model of Functioning of a Thing in the System of Contemporary Design
Authors: Yurchenko Ihor
Published: November 2024

The purpose of the article is to build the model of the functioning and role of a thing in the system of contemporary design. Research methods. The article applies general scientific methods and approaches of cognition, namely: interdisciplinary and systematic approaches, analysis, synthesis, deduction and induction; abstraction method, method of ascent from the general to the specific, empirical method of collecting information. The method of Gestalt psychology was used to determine the specifics of combining the constituent elements into holistic configurations. Scientific novelty. The article presents a systematic analysis of the functioning of a thing in contemporary design as a holistic model. In the course from the general to the specific, the constituent elements of the model have been defined, which can be in static and dynamic states of development. The static and dynamic aspects of development depend on the pre-project conditions and technical specifications, requirements of the consumer of design objects, and methods of technological production of a thing. Conclusions: It is found that a thing in contemporary design performs several functions in the subsystem "thing-consumer-socio-cultural environment" simultaneously. Through constant filling, changes, redesign of the object environment, a thing influences the formation of visual culture, creates a general image of the socio-cultural environment saturated with visual expressiveness. In this way, the old image of object culture is constantly replaced by a new one. The type of consumer and customer, depending on the value orientations formed by the socio-cultural environment, determines specific design features of the project image of a thing, from the instrumental minimalism of its form to the complexity of the form as an art object. Pre-project research, design, and formation of things are subject to universal tasks, principles, techniques, and methods. The updated image of the socio-cultural environment, composed of object forms, actively influences and determines the prerequisites for the emergence of new ideas of things. The formulated levels of quality assessment of the implementation of the functional and ergonomic task in the formation of design objects consist in thorough pre-design research, quality of design work, and the production of the form of a thing.

Published: November 2024

This research analyzes the connection of Regulatory Quality (RQ) and Rule of Law (ROL) on Foreign Direct Investment (FDI) in ASEAN countries between 2002 to 2022. Utilizing the pooled mean group (PMG) technique with data sourced from the World Bank, the study found that Regulatory Quality significantly impacts FDI in the long term. Short-term results indicate significant corrections to the divergence of the long-term equilibrium production levels. Causality tests reveal a two-way relationship between FDI and Regulatory Quality in ASEAN countries, but no reciprocal relationship with Rule of Law was identified.
DETERMINATION OF THE STYLISTIC FEATURES OF THE HISTORSCAL BUILDINGS OF KROPYVNYTSKYI ON THE EXAMPLE OF TEATRALNA STREET
Authors: Penyaz Tatyana
Published: November 2024

Studying and preserving the historical and cultural heritage of Ukraine's regional and local centres is important for understanding the peculiarities of the nation development and its culture. Kropyvnytskyi (Yelisavethrad) represents the peculiarities of the formation of the national identity of the central Ukrainian region.The transition from the nineteenth to the twentieth century was marked by a surge in the stylistic development of the city's architecture. The most striking embodiment of the style trends of the late nineteenth and early twentieth centuries was the architecture of mansions and city residential buildings with commercial premises.The purpose of the publication is to identify the peculiarities of the formation of the modernised neoclassicism in Kropyvnytskyi (Yelisavethrad), thanks to the work of architects O. Lishnevsky and Y. Pauchenko, graduates of St. Petersburg and Moscow architectural schools, who were born in Ukraine and whose creative path is connected with Yelisavethrad.The main streets of the city in the late nineteenth and early twentieth centuries were V. Perspektyvna Street, which housed the main administrative, financial and commercial institutions, the best hotels and apartment buildings - a kind of business centre, and Teatralna (Dvortsova) Street, where educational, spectator, commercial institutions and private houses of wealthy citizens were built - a cultural and entertainment centre.On Teatralna (Dvortsova) Street, whose buildings represent the directions and trends of classicism, historicism, and modernism, two early twentieth-century buildings stand out for their restraint and majesty, representing the trend of modernised neoclassicism of the early twentieth century, which was distinguished by the clarity and structure of classical forms with the use of constructive and compositional techniques developed by modernism. These are the house of the mayor H. Volokhin (1911-1918) at 10 Teatralna Street and the house of the famous Yelisavetgrad photographer D. Harlab at 17/7 Teatralna Street.

Authors: Emamianfar Ali , Tretiak Yuliia , Kosarevska Raddamila
Published: November 2024

The article highlights a comprehensive approach to the architectural design of school buildings in Iran, with an emphasis on the climatic features of cold and humid regions. Special attention is paid to temperate and cold humid zones located mainly in the north and west of the country, including the coast of the Caspian Sea and the Alborz mountain range.
The focus of the research is the analysis of architectural features adapted to the specifics of the climate of these regions, such as the orientation of the building, air conditioning systems, classroom lighting, the use of vegetation to create shading, as well as the features of the form, interior design and choice of materials. Particular attention is paid to the energy efficiency of school buildings, as schools are significant consumers of energy, including electricity, water and gas. Architectural solutions based on a deep understanding of climatic conditions can significantly improve the energy efficiency of schools, reduce fuel consumption and contribute to the creation of a comfortable and healthy learning environment.
The article emphasizes the importance of an integrated approach to architectural design, which takes into account climatic features to increase energy efficiency and create optimal conditions for learning and development of students in schools in cold and humid regions of Iran.
FEATURES OF THE FUNCTIONAL AND PLANNING ORGANIZATION OF MODERN CENTERS OF SOCIAL AND PSYCHOLOGICAL REHABILITATION
Authors: Shkliar Svitlana , Voronovskyi Ivan
Published: November 2024

The article reveals the main differences between social and psychological rehabilitation centers and other types of rehabilitation institutions. The main feature of the socio-psychological rehabilitation center, which significantly distinguishes it from other types of rehabilitation institutions, is its focus not only on the restoration of physical health, but also on the stabilization and maintenance of psycho-emotional health, on the social integration of a person. That is, social and psychological rehabilitation centers ensure preservation, restoration and support of the mental health of the population.Priority categories of rehabilitators are considered in the work. Currently, two categories of population need social and psychological rehabilitation in Ukraine: 1) military personnel (military personnel and war veterans); 2) civilian population (civilian citizens who suffered as a result of hostilities; children who suffered as a result of hostilities or lost relatives; members of families of military personnel; relatives of deceased military personnel). Considering the fact that hostilities in the country continue, the priority category of rehabilitators should be military personnel.The study identifies and analyzes the features of the functional and architecturalplanning structure of social-psychological rehabilitation centers. In the architectural context, the expansion of the range of services of rehabilitation centers and their orientation towards the restoration of the mental health of rehabilitates leads to the formation of additional functional blocks: leisure, educational and professional, socio-economic services, recreational, communicative, non-traditional types of therapy (canister therapy, hippotherapy, occupational therapy, art -therapy, etc.). The greater the number of additional functions in the social-psychological rehabilitation center, the greater its effectiveness. Therefore, the ratio of the areas of the main and additional functional blocks is almost equalized. At the same time, in proportion to the number of functions, the area of the territory and the volume of the building of the rehabilitation center increase, the compositional and planning construction and the system of functional connections become more complicated. Therefore, when developing projects of centers of social and psychological rehabilitation, not only the requirements of architectural accessibility should be taken into account, but also planning and constructive schemes should be laid, which provide for the possibility of additions and expansion of the building.

Authors: Chughtai Sufian , K Kathirasan , Rai Sunita
Published: November 2024

The 8-week Mindfulness-Based Wellbeing Enhancement (MBWE) program was designed to enhance mental wellbeing across diverse populations. This evaluation report presents findings from two studies assessing the program’s effectiveness. In Study 1, pre- and post-program assessments using the Five Facet Mindfulness Questionnaire (FFMQ) revealed significant improvements across all facets of mindfulness, demonstrating the program's efficacy in cultivating mindfulness among participants. Study 2 examined human flourishing outcomes through self-reported data collected at the program's conclusion, with participants consistently reporting enhanced mental wellbeing across multiple dimensions. Although the absence of control groups in both studies limits the ability to definitively attribute these outcomes to the MBWE program, the overall findings indicate that the MBWE program effectively promotes mindfulness and supports broader mental wellbeing.

Authors: Sufelfa A. R. , Voznesensky A. S. , Kaplun D. I.
Published: November 2024

Introduction. Formation of a contact surface in prosthetics and orthotics is crucial for the restoration of human musculoskeletal functions. This paper considers specific features of methods currently used for denoising of a 3D model surface obtained by optical scanning. An algorithm for manufacturing an individual prosthetic and orthopedic product is developed. The current literature reports no similar methods, which may be explained by the widespread use of gypsum technology for the manufacture of prostheses and orthoses.

Aim. Research and development of digital filtration methods for 3D meshes obtained by optical scanning for further modeling of individual prosthesis and orthosis modules.

Materials and methods. It is proposed to optimize the pre-processing stage of 3D scanned models by applying denoising and smoothing processes. In total, 50 optical 3D scans were selected for testing via the following denoising algorithms: bilateral filtering, vertex-based anisotropic smoothing, mean and median filtering applied to face normals.

Results. The study was conducted using 3D scans of lower limb stumps and Chenault brace orthoses and corsets provided by the Institute of Prosthetics and Orthotics, Albrecht Federal Scientific and Educational Centre of Medical and Social Expertise and Rehabilitation. А method for denoising and smoothing of the 3D model surfaces for the manufacture of prosthetic and orthopedic products is proposed. The SNR metric difference SNR – δ-SNR (with averaging by scans and SNR values) and average execution time were calculated. The bilateral filtration method with δ-SNR = 11.3362 dB and a runtime of 8.8900 s showed the highest efficiency.

Conclusion. The proposed methods for the pre-processing stage of 3D optical scans showed high efficiency in the formation of 3D models of prosthesis and orthosis modules. The results obtained can be used for automating the process of manufacturing various prosthetic and orthopedic products, which is particularly relevant in the context of the modern geopolitical situation.

Authors: Laptev K. Yu. , Sokolov N. V. , Mikhailov V. N. , Bogachev M. I. , Vorobev E. N.
Published: November 2024

Introduction. Remote sensing and monitoring of the sea surface are of great importance in such fields, as operational oceanography, environmental monitoring, etc. The ability to quickly assess the state of the sea surface is particularly relevant in areas that pose a danger to shipping, where rapid and accurate response becomes critical. Modern radars represent information as digital image series largely reminiscent to a frame series in a video stream, thus enabling the use of gradient methods originally designed for and proven successful in video analysis.

Aim. Determination of sea wave characteristics from radar images using gradient motion estimation methods. The use of gradient methods will allow implementing additional tools for processing radar image series obtained from sea backscatter.

Materials and methods. To assess the characteristics of the sea surface from radar images, gradient methods were used. To train the methods, a series of synthetic images of the sea surface obtained by mathematical modeling were used. To evaluate the effectiveness of the gradient methods, two representative experimental radar image series provided by the Institute of Oceanography RAS were employed.

Results. Using gradient methods, the direction and speed of waves were calculated from several consecutive radar observations. Regression models of the dependence of calculated values on the specified ones were constructed. The Farneback and TV-L1 methods proved to be effective especially for obtaining the direction of the sea waves.

Conclusion. An algorithm for evaluating speed and direction of the sea surface displacement using gradient methods was pre-trained using simulated model data. The implemented methods and algorithms for assessing the speed and direction of sea waves were validated using two experimental image series obtained from shipborne navigational radars.
Separation of Cyclostationary Signals and Interference in Transmission Lines of Printed Circuit Boards Based on Independent Component Analysis
Authors: Kuznetsov Yu. V. , Baev A. B. , Konovalyuk M. A. , Gorbunova A. A.
Published: November 2024

Introduction. When developing and testing high-speed communication links of digital electronic devices, the pulse shape of electrical signals and interference in transmission lines is commonly controlled using eye diagrams. Partial pulse responses are estimated by modern multi-channel testing and measuring equipment using specific testing procedures. Aim. To develop an approach to blind identification of a wireline communication signal measured by a digital oscilloscope in microstrip transmission lines.

Materials and methods. The study was carried out using a communication signal model composed of a superposition of the information signal, intersymbol interference, and crosstalk interference from an adjacent transmission line, with the symbols of these signal sources being assumed statistically independent. The implemented blind identification method makes it possible to separate three components of the signal and evaluate their partial pulse responses. The proposed procedure for signal separation includes preliminary processing of the data measured by principal component analysis followed by an analysis of independent components based on fourth-order statistical characteristics.

Results. The performance of the proposed signal separation method is demonstrated using the results of parallel and independent data processing measured in microstrip transmission lines in an experimental setup with two closely spaced printed circuit boards. A comparison of blind signal separation methods is carried out based on second-order statistics, fourth-order cumulants, and independent component analysis. The proposed method of independent component analysis demonstrated the highest efficiency in terms of minimum bit error probability for blind signal separation with arbitrary partial pulse responses, which was confirmed by simulation results.

Conclusion. The developed approach to blind identification of wireline signal parameters measured in high-density integrated digital electronic devices extends the range of systems for circuit design and testing of multi-channel high-speed communication lines.
Algılanan Kıtlık Durumunun Ve Demografik Özelliklerin Tüketicinin Panik Satın Alma Davranışı Üzerindeki Etkisi
Authors: Topçu Tuğçe , Yeniçeri Tülay

Panik satın alma davranışı; belirli olumsuz duyguların davranışı etkileyerek insanları normalden daha fazla şey satın almaya yönlendirmesi sonucunda ortaya çıkmaktadır. Farklı demografik ve psikolojik özellikler panik satın alma davranışının belirleyicisi niteliğinde olup aynı zamanda tüketicileri panik satın alma davranışını tetikleyen etkenlerden birisi algılanan kıtlıktır. Herhangi bir ürünün kısıtlanması durumunda ortaya çıkan kıtlık algısının olması durumu tüketicileri panik satın alma davranışına yönlendirmektedir. Bu bağlamda araştırmanın amacı; tüketicilerin algılanan kıtlık durumlarının panik satın alma davranışları üzerinde bir etkisi olup olmadığını, aynı zamanda tüketicilerin panik satın alma davranışlarını; belirli demografik değişkenler açısından araştırmak ve bu değişkenler arasında anlamlı bir farklılığın olup olmadığını tespit etmektir. Bu amaca yönelik olarak çevrimiçi anket yöntemiyle 389 katılımcıdan veriler toplanmıştır. Yapılan analiz sonucunda, algılanan kıtlık ile panik satın alma davranışı arasında orta düzeyde anlamlı ve pozitif yönde korelasyon ilişkisi olduğu ve algılanan kıtlık durumunun panik satın alma davranışını anlamlı düzeyde açıkladığı görülmektedir. Verilerin normal dağılım göstermesinden dolayı parametrik testler kullanılarak hipotezler test edilmiştir. Yapılan analizler doğrultusunda tüketicilerin panik satın alma davranışları cinsiyet, yaş ve medeni durum değişkenlerine göre anlamlı bir farklılığa sahipken aylık gelir ve öğrenim düzeyleri açısından anlamlı bir farklılığın olmadığı tespit edilmiştir.

ÖZ
Meşrutiyetin en temel tartışmalarından birinin modernleşme ve gelenek arasındaki ilişkiler etrafında döndüğü bir gerçektir. Bu bağlamda Ziya Gökalp’in İslam Mecmuası’nda gündeme getirdiği bir tartışma, gelenek içinde önemli bir yer tutan fıkıh sisteminin değişmeye ne kadar açık olup olmadığı meselesidir. Bugün de farklı biçimlerde tartışılan bu konu, aslında nas ile olgu arasındaki ilişkilerin mahiyeti etrafında dönüp dolaşmaktadır. Bir başka deyişle ilahi ve değişmez bir kurallar bütünü olan fıkıh, değişen toplumsal olguları ne kadar hesaba katmalıdır? Bu konuda günümüzde halen devam etmekte olan tartışmaları da içerek şekilde bir kuramsal tipoloji oluşturmak ve bu tartışmada yer alan aktörleri konumlandırmak meseleyi açıklığa kavuşturmak açısından büyük önem taşımaktadır.
İslamcılar başta olmak üzere pek çok Osmanlı aydını yeni sorunlarla baş edebilmek için İslam fıkhının yenilenmesini ve içtihat kapısının açılmasını talep etmektedir. Ancak bunun nasıl olacağı konusunda farklı fikirler sunulmaktadır. Ziya Gökalp İslam Mecmuası’nda bu konuda kendi fikirlerini “içtimai fıkıh” ve “içtima-i usul-i fıkıh” kavramlarıyla açıklamıştır. Bu çalışmamız tam da bu tartışmaları çıkış noktası alarak şu temel soruya cevap aramaktadır: 20. yüzyılın başında fıkıh-sosyoloji ilişkileri bağlamında içtimai fıkıh tartışması konusunda Ziya Gökalp nasıl öncülük yapmıştır? Bu konuda temel fikirleri ve önermeleri nedir? Görüşleri ve konumu, olgu-nas ilişkileri bağlamında nereye oturmaktadır? Makale, Ziya Gökalp’in İslam Mecmuası’nda yazdığı iki önemli metni esas alarak bir analiz yapmakta ve onun konumunu açıklığa kavuşturmaktadır.

Service quality is the comprehensive support provided by system developers to users to ensure safety, comfort, empathy and responsiveness in meeting user expectations. There are still complaints about the Maxim application in the Google Playstore review from January 16 to February 12, 2024, inaccurate pick-up or destination, inconsistent prices, slow service response so that users have difficulty getting solutions to problems. Supported by the INDEF (Institute for Development of Economics and Finance) survey on DataIndonesia.id that the popularity of Maxim's services is lower than Gojek and Grab. Thus, it is essential to employ the E-Servqual approach to perform research to determine whether the services have satisfied users. Because its dimensions are pertinent and completely satisfy the requirements of assessing the quality of electronic services, E-Service Quality is the most thorough and integrative online service quality model. Efficiency, fulfillment, system availability, privacy, responsiveness, compensation, and interaction are the seven factors used, while user satisfaction is the dependent variable. This kind of study collects data using nonprobability sampling approaches in conjunction with quantitative methods. wherein demographic components are chosen according to specific standards that are pertinent to the study's goals. Considering the findings of the analysis, the 7 proposed hypotheses consisted of 3 accepted hypotheses and 4 rejected hypotheses because the significance value alpha (α = 0.05) and 4 hypotheses rejected because the significance value alpha (α = 0.05. Overall, the quality of Maxim's service towards user satisfaction is not good in terms of the variables of efficiency, system availability, responsiveness, and contact. It is hoped that there will be improvements in the Maxim application such as application usage, application functions on the displayed page, application response, and contact services for communication

Published: November 2024

The climate in Indonesia, which is a tropical region, is always uncertain and makes it difficult to predict weather conditions. Weather conditions can be influenced by rainfall, air temperature, wind speed, air humidity and light radiation intensity. Rainfall is relatively high and varies throughout the year, the average monthly rainfall is around 150-300 mm in the rainy season and 50-100 mm in the dry season. There are several characteristics of rainfall, namely convective rain, frontal rain and orographic rain. For this reason, a method is needed that can solve problems in predicting monthly rainfall properties using the Monte Carlo simulation method. From this study, the results of the prediction of rainfall properties were obtained with 36 data from 2021 to 2024 which had a MAPE test result of 12.28%. The test results came from the average calculation carried out on the Monte Carlo method prediction with 5 variables.
