Ukrainian Folk Games and Toys: Levels of Integration Into Modern Visual Culture
Authors: Skliarenko Nataliia , Shkliaieva Nataliia , Pylypiuk Larysa 
Published: April 2024

Summary
The study deals with the possibilities of integrating the folk experience of creating Ukrainian games and toys into modern visual culture. An ethno-cultural pattern that synthesizes the artistic image, national form, natural materials, and game principles of interaction into an integral structure based on the analysis of folklore materials and artistic folk products from the territory of Western Polissia in Ukraine has been formed. The result of the study is the classification of Ukrainian folk toys and games of the population of Western Polissia organized as a holistic multifaceted visual and communicative system of interaction between folk games and toys. It has been proved that integration of ethno-cultural patterns into modern visual culture is carried out on three levels: subject, environmental, and socio-cultural. The study presents the theoretical basis for designing a modern visual and communicative environment for life, learning and rest, which is able to attract a child to the deep traditions of national culture in a natural way.
The outlined levels of integration are closely related with modern practices of eco-design, ethno-design, and art-therapy, which act as a strategic basis for the formation of modern visual culture and are aimed at the sustainable development of society.
Iconography as System. The Structural Principles of Representation in Visual Culture
Authors: Ibero Álvaro 
Published: April 2024

Summary
This paper constitutes a reflexive and theoretical approach to the study of iconographies from a cultural perspective. Its aim is to depict iconographies as the structural order which makes images representative of the social frameworks from which they stem. By analysing the stable principles which participate in the production of such representativity in any given iconography, and by considering the cultural agents which socially regulate them and make images culturally specific, it is possible to understand the cultural mechanisms by which the social construction of reality is projected onto images. Consequently, this approach favours a conceptualisation of iconographies as cultural systems through which the identity of social frameworks is conveyed thanks to the use of images.
Compensation for Establishing Transmission Line Easement: Parts of Land Affected and Persons Involved
Authors: Bogdan Benon , Barańska Anna 
Published: April 2024

Abstract
The identification of the scope of the limited property law (that is transmission easement), as well as the taking of appropriate actions, has become difficult. The far from sufficient implementation of rules has led to numerous disputes, the resolution of which has been sought in court. Very generalized legal bases, interpretation of regulations and the acceptance of the rulings of common courts have made the development of operating procedures possible and have determined the persons participating in performing work related to transmission easement.
The specifics and the multidimensionality of the subject requires cooperation from several experts. The methodological bases are limited, and the regulations unclear. The goal of the research is the standardization of designations of component parts and activities associated with transmission easement. The entire process is made easier by a set procedure proposed in the form of an outline. This study draws attention to individual activities and the order in which they are performed. This allows individual specialists to carry out the next stages of work, which in turn leads to sanctioning the rights of the grantee, while determining fair and satisfactory compensation for the grantor.
The Impact of the Flight to Quality on Office Rents and Vacancy Rates in Tokyo
Authors: Matsuo Kazushi , Tsutsumi Morito , Imazeki Toyokazu , Kudoh Takeshi 
Published: April 2024

Abstract
With the rapid spread of telecommuting since the COVID-19 pandemic, companies have been relocating to high-end business centers, thereby enhancing the workplace experience for employees, a phenomenon called the "flight to quality." However, this trend’s impact on rents and vacancy rates in individual office buildings has not been extensively studied. To determine the effects of the flight-to-quality phenomenon on individual buildings, we examine the impact of modern amenities, which directly influence employee lifestyles, on rents and vacancy rates in the Tokyo office market. Using a propensity score-based quasi-experimental method, we find that commercial properties with such modern amenities command higher rents and experience lower vacancy rates than those without. The difference in vacancy rates has increased since 2020. However, the significance of these amenities diminishes for properties less competitive in age, size, and location. The results indicate that the "flight to quality" may further polarize the office real estate market into two categories: one for high-end buildings experiencing increasing demand, and another for those with modest amenities experiencing decreasing demand. The findings have implications for office building owners/investors and the government, make educated decisions as to whether to invest in modern amenities, join the quality competition, or encourage urban restructuring.

A Systematic Review on Non-Orthogonal Multiple Access (NOMA) Based on Visible Light Communication for Intelligent Transportation Systems
Authors: Yosef Seba Adnan , Abdulameer Lwaa Faisal 
Published: April 2024

Non-Orthogonal Multiple Access (NOMA) is a cutting-edge technology that permits several users to use the same frequency resources and transfer data at once. Visible light communication also known as VLC, is an innovative technology that offers access to an unoccupied spectrum, enables fast data transmission speeds, thereby making it a complementary addition to current radio frequency technology. Although VLC has its advantages, it also comes with some downsides. One major issue is the modulation bandwidth of LEDs, which can be quite challenging when creating high speed VLC systems. Non-orthogonal multiple access (NOMA), particularly power-domain NOMA (PD-NOMA), has become a viable multiple access approach, ensuring sufficient bandwidth allocation for VLC systems. This study delves into multiple access techniques in VLC systems, in particular NOMA, and discusses its fundamental principles, key ideas and practical implementations like vehicular communication. It also addresses the associated hurdles, such as ensuring equitable distribution of optical power among users, leveraging MIMO technology, and grappling with LED nonlinearity issues. In summary, we underscore the significance of utilizing NOMA-VLC technology to enhance wireless communication systems and optimize spectral efficiency.

Authors: Белкин Антон Эдуардович , Бирюков Данила Русланович 
Published: April 2024

В статье поставлена задача о рассеянии конечного плоского нестационарного акустического импульса упругим неоднородным изотропным цилиндром, расположенном в идеальной жидкости. Для решения задачи использовано интегральное преобразование Фурье. Для решения задачи пространство разделяется на внешнюю область, в которой изображение искомой рассеянной волны ищется в виде бесконечного ряда с неизвестными коэффициентами, и внутреннюю область, содержащую упругий цилиндр, которая подвергается дискретизации. Решение системы линейных алгебраических уравнений, которая строится на основе конечно-элементной модели в соответствии с методом Галеркина, позволяет определить коэффициенты изображения рассеянной волны. Задача и алгоритм её решения представляют интерес для дальнейшего изучения возможности определения рассеянных волновых полей в случаях, когда не представляется возможным применять аналитические методы.
The article poses the problem of scattering a finite plane non-stationary acoustic pulse by an elastic inhomogeneous isotropic cylinder located in an ideal fluid. To solve the problem, the integral Fourier transform was used. To solve the problem, the space is divided into an external region, in which the image of the desired scattered wave is sought in the form of an infinite series with unknown coefficients, and an internal region containing an elastic cylinder and subject to discretization. The solution of a system of linear algebraic equations, which is constructed on the basis of a finite element model in accordance with the Galerkin method, allows one to determine the image coefficients of the scattered wave. The problem and the algorithm for solving it are of interest for further study of the possibility of determining scattered wave fields in cases in which it is not possible to use analytical methods.

MEXICO’S DEMOCRACY UNDER THREAT? EFFECTS OF FEAR AND CORRUPTION IN MEXICO: UPDATED
Authors: Norris James Arthur , Norris Lola Orellano 
Published: April 2024

Purpose: The purpose of this study is to expose public attitudes in Mexico towards the perceived success or failure of democracy in the country, and possible support for authoritarian alternatives that might be perceived as more successful in delivering justice and security.

Theoretical Framework: Mexico’s new democracy has stalled due to severe and persistent corruption scandals and an overwhelming security and justice crisis, heightened by an explosion of violence associated with narcotics trafficking organized crime. The situation is serious enough to question the survival of democracy in Mexico.

Design/Approach: This paper presents and analyzes data from the Americas Barometers of 2006 - 2019 that cover the main period of extreme insecurity in Mexico.

Findings: The article confirms that Mexicans are disappointed with the way democracy works in Mexico. Their frustration is driven by several factors: perceptions of political corruption, concerns for the country’s safety and security, and their economic situation. The most salient concerns have to do with corrupt politicians and security. A substantial proportion of the Mexican public is considering trading democracy for security.

Research, Practical, & Social Implications: Further study should examine if there is support for extra-legal suppression of crime, if support has increased perhaps out of frustration, and the complex relationship Mexicans have with the widespread perception that both the political system and the justice system is irrevocably corrupt.

Originality/Value: The issue of the survival of nascent democracy is of great interest in comparative politics and Latin American studies. The broader question is how to help youg democracies mature into healthy democracies.
Der assistierte Suizid – vermeintlich ultimativer Ausdruck bürgerlicher Freiheit?
Authors: Altschäffl Regina M. , Bauer Axel W. 
Published: April 2024

Abstract
Am 26. Februar 2020 erklärte das Bundesverfassungsgericht den § 217 StGB zur Regelung der geschäftsmäßigen Förderung der Selbsttötung für verfassungswidrig. Die daraufhin eingereichten beiden Gesetzesentwürfe wurden im Juli 2023 im Deutschen Bundestag abgelehnt. Daher gibt es derzeit noch keine neue gesetzliche Regelung der Suizidhilfe. Zur Suizidassistenz wird im Ausland meist das Betäubungsmittel Natrium-Pentobarbital eingesetzt, was durch das deutsche Betäubungsmittelgesetz (BtMG) aber verboten ist. Eine alleinige Änderung des BtMG wäre daher eine denkbare Alternative zu einem neuen Suizidhilfegesetz, jedoch sicher keine Hilfe zum Lebensschutz.

OBJECTIVE
The utilization of digital technologies has experienced a notable surge, particularly in cases where access to cadavers is constrained, within the context of practical neuroanatomy training. This study evaluates augmented reality (AR)– and virtual reality (VR)–based educational models for neuroanatomy education.

METHODS
Three-dimensional models were created using advanced photogrammetry. VR- and AR-based educational models were developed by arranging these 3D models to align with the learning objectives of neurosurgery residents and second-year medical students whose cadaveric training was disrupted due to an earthquake in Turkey. Participants engaged with and evaluated the VR- and AR-based educational models, followed by the completion of a 20-item graded user experience survey. A 10-question mini-test was given to assess the baseline knowledge level prior to training and to measure the achievement of learning objectives after training.

RESULTS
Forty neurosurgery residents were trained with a VR-based educational model using VR headsets. An AR-based educational model was provided online to 200 second-year medical students for their practical neuroanatomy lesson. The average correct answer rates before the training were 7.5/10 for residents and 4.8/10 for students. These rates were significantly improved after the training to 9.7/10 for residents and to 8.7/10 for students (p < 0.001). Feedback from the users concurred that VR- and AR-based training could significantly enhance the learning experience in the field of neuroanatomy.

CONCLUSIONS
VR/AR-based educational models have the potential to improve education. VR/AR-based training systems can serve as an auxiliary tool in neuroanatomy training, offering a realistic alternative to traditional learning tools.

OBJECTIVE
Language dominance in the developing brain can vary widely across anatomical and pathological conditions as well as age groups. Repetitive navigated transcranial magnetic stimulation (rnTMS) has been applied to calculate the hemispheric dominance ratio (HDR) in adults. In this study, the authors aimed to assess the feasibility of using rnTMS to identify language lateralization in a pediatric neurosurgical cohort and to correlate the preoperative rnTMS findings with the postoperative language outcome.

METHODS
A consecutive prospectively collected cohort of 19 children with language-associated lesions underwent bihemispheric rnTMS mapping prior to surgery (100 stimulation sites on each hemisphere). In addition to feasibility and adverse effects, the HDR (ratio of the left hemisphere to right hemisphere error rate) was calculated. The anatomical surgical site and postoperative language outcome at 3 months after surgery were assessed according to clinical documentation.

RESULTS
Repetitive nTMS mapping was feasible in all 19 children (mean age 12.5 years, range 4–17 years; 16 left-sided lesions) without any relevant adverse events. Thirteen children (68%) showed left hemispheric dominance (HDR > 1.1), and 2 children (11%) showed right hemispheric dominance (HDR < 0.9). In 4 children (21%), the bihemispheric error rates were nearly the same (HDR ≥ 0.9 and ≤ 1.1). Sixteen children underwent surgery (14 tumor/lesion resections and 2 hemispherotomies) and 3 patients continued conservative therapy. After surgery, 4 patients (25%) showed an improvement in language function, 10 (63%) presented with stable language function, and 2 (12.5%) experienced deterioration in language function. Of the 6 patients with right hemispheric language involvement, 4 (80%) had glial tumors, 1 (20%) had focal cortical dysplasia, and 1 (20%) experienced hypoxic brain injury. Children with right hemispheric language involvement (HDR ≤ 1.1) did not show any language deterioration postoperatively.

CONCLUSIONS
Bihemispheric rnTMS language mapping as a noninvasive mapping technique to assess lateralization of language function in the pediatric neurosurgical population is safe and feasible. Why relevant right hemispheric language function (HDR ≤ 1.1) was associated with postoperative unaltered language function needs to be validated in future studies. Bihemispheric rnTMS language mapping strengthens risk-benefit considerations prior to pediatric tumor/epilepsy surgery in language-associated areas.

Published: April 2024

OBJECTIVE
In this study, the authors aimed to determine the mid- to long-term outcomes of microendoscopic laminotomy (MEL) for lumbar spinal stenosis (LSS) with degenerative spondylolisthesis (DS) and identify preoperative predictors of poor mid- to long-term outcomes.

METHODS
The authors retrospectively reviewed the medical records of 274 patients who underwent spinal MEL for symptomatic LSS. The minimum postoperative follow-up duration was 5 years. Patients were classified into two groups according to DS: those with DS (the DS+ group) and those without DS (the DS− group). The patients were subjected to propensity score matching based on sex, age, BMI, surgical segments, and preoperative leg pain visual analog scale scores. Clinical outcomes were evaluated 1 year and > 5 years after surgery.

RESULTS
Surgical outcomes of MEL for LSS were not significantly different between the DS+ and DS− groups at the final follow-up (mean 7.8 years) in terms of Oswestry Disability Index (p = 0.498), satisfaction (p = 0.913), and reoperation rate (p = 0.154). In the multivariate analysis, female sex (standard β −0.260), patients with slip angle > 5° in the forward bending position (standard β −0.313), and those with dynamic progression of Meyerding grade (standard β −0.325) were at a high risk of poor long-term outcomes.

CONCLUSIONS
MEL may have good long-term results in patients with DS without dynamic instability. Women with dynamic instability may require additional fusion surgery in approximately 25% of cases for a period of ≥ 5 years.
