Introduction. Injuries to the ureter occur in 1-2,5% of cases of all lesions of the genitourinary organs. Iatrogenic injuries account for more than 80% of cases. Their number is associated with the active application of minimally invasive treatment methods into practice. The choice of reconstructive surgery in these patients depends on the functional state of the kidneys and ureters, the extent and level of stricture. Of particular importance is theBoari technique, which is associated with the general embryogenesis of the lower urinary tract. If there is tension in the anastomosis ar ea, it is preferable to use the psoas-hitch technique.

Materials and methods. The work was based on the results of the treatment of 42 patients undergoing inpatient treatment at the MC «Medassist» clinic from 2019 to 2024. All patients underwent laparoscopic ureteral plastic surgery using the Boari and psoas-hitch techniques.

Results. According to MSCT of the urinary system, no relapse was detected in any of the subjects during the follow-up period. With dynamic nephroscintigraphy after surgical treatment, an improvement in the functional parameters of kidney function was recorded in most patients (n=39; 92,9). According to ultrasound data, passive reflux was noted in 15 (35,7%) patients. Pyelonephritis occurred in 3 (7,1%) patients, all of whom had a urological history. According to the cystometric study, there was no reliable relationship between the volume of the flap used and the development of dysfunctional urination; detrusor hyperactivity of the detrusor before surgery was detected in 7,1% of cases (n=3); after surgery – 9,5% of cases (n=4); no clinically significant change in the maximum cystometric capacity after such a benefit was recorded.

Conclusions. Reconstructive surgery for iatrogenic injuries of the lower third of the ureter using Boari and psoas-hitch techniques is effective in 92,9% of patients. 35,7% of patients in the postoperative period had clinically insignificant passive vesicoureteral reflux. Patients with a history of infravesical obstruction, bladder surgery or repeated plasty using flap techniques, and external radiation therapy to the pelvic organs have a high risk of recurrent urinary infection due to active and passive reflux. Cystometry revealed no significant relationship between the length of the bladder flap used and the development of dysfunctional urination.

Authors: Leela C P  , Nagashree N  , Smithu B S
Published: February 2025

Have you ever considered the idea of making things appear invisible, similar to the concept of the invisibility cloak in Harry Potter. An invisible cloak, as popularized in fiction like Harry Potter, is a hypothetical concept where a garment or device renders the wearer invisible to the naked eye. In reality, such technology doesn't exist, and achieving invisibility involves complex scientific and optical challenges. While there have been advancements in camouflage and stealth technology, creating a true invisible cloak remains a subject of fascination and imagination in the realms of science fiction and fantasy. While we know there's no actual magic involved, achieving this effect in movies relies on graphic tricks. The concept of an invisibility cloak is a blend of science, fantasy, and human imagination. This project explores how to create your own "Invisibility Cloak" using Python and the OpenCV module, focusing on image processing and segmentation. It delves into manipulating objects of specific colours or textures using OpenCV. The process involves capturing and storing the background frame, identifying red, blue, and green-coloured fabric through algorithms, creating a mask to isolate the RGB-coloured fabric, and ultimately generating a magical augmented output to simulate an invisibility cloak.

Green computing has become increasingly relevant in today's digital era. This approach is aimed at minimizing environmental impact through the efficient use of computing resources. This study evaluated the awareness, knowledge, and practices of IT professionals regarding green computing to understand their role in promoting sustainable technology use. Utilizing a mixed-methods approach, the research combined quantitative surveys and qualitative interviews, collecting data from 100 IT experts across 32 randomly selected IT companies in Manila. The quantitative analysis involved calculating means and standard deviations to assess the central tendencies of green computing adoption, while Levene's test and a t-test were conducted to compare variances and means between the two groups. The findings indicate no significant differences in awareness and knowledge of green computing between public and private sector IT professionals, with public sector professionals showing slightly higher awareness and knowledge scores. However, the practices of green computing differ significantly, with private sector professionals demonstrating a higher level of application. These results suggest the need for targeted initiatives to enhance green computing practices across both sectors, with policy recommendations aimed at fostering greater adoption of sustainable IT practices.

Published: February 2025

Modern marketing tactics and corporate operations have been impacted by the development of data privacy laws, which have altered how businesses gather, store, and use customer data. Concerns regarding data security and privacy have been highlighted by businesses' growing dependence on customer data for strategic decision-making and targeted advertising. To ensure accountability, transparency, and the preservation of consumer rights, governments throughout the world have responded with strict laws like the California Consumer Privacy Act (CCPA) and the General Data Preservation Regulation (GDPR) of the European Union. These policies radically change data management techniques by imposing stringent compliance criteria including user permission, data minimization, and access rights. Although compliance gives companies the chance to build their brand and draw in new customers, it also comes with drawbacks including high operating expenses, intricate data processing, and certain legal risks. This study looks at how data privacy laws affect marketing tactics, highlighting the move towards privacy-first initiatives, anonymised data usage, and safe online interactions. To identify new trends, obstacles, and best practices in privacy-compliant marketing, the study qualitatively analyses secondary sources, such as scholarly publications, official documents, and case studies. The results show how crucial it is for companies to include data privacy into their strategic planning to balance competitive advantage with regulatory compliance. Organizations must proactively adjust as global privacy standards continue to change in order to stay in compliance and cultivate client relationships in a market where privacy concerns are on the rise.

Authors: Aimuamwonsa Osahenoto Monebi  , Osarobo Osamede Ogbiede
Published: February 2025

Unscheduled preventive maintenance negatively impacts product quality and increases production time due to downtime and emergency shutdowns, raising production costs. We propose a decision support methodology to enhance equipment availability by analyzing historical time to repair (TTR) data using statistical analysis in Minitab. This study analyzed TTR data from seven machines (Filler, Mixer, Blowmould, Labeller, Variopac, Palletizer, and Conveyor) on a production line for 2022. The analysis included both parametric and non-parametric methods, with results presented graphically to summarize statistics like cumulative repair time probability (CRTPR1) and the hazard rate. Using least squares probability fitting, we found that five machines followed an exponential distribution, while the Palletizer and Mixer exhibited log-normal distributions. All machines had about a 63% probability of completing repairs within the meantime to repair (MTTR), except the Palletizer and Mixer, which showed less than 1% probability.
6G wireless networks and terahertz communications: Intelligent reflecting surfaces, MIMO, and Energy-Efficient IoT architectures
Authors: Julien Kiesse Bahangulu
Published: February 2025

The advent of 6G wireless networks marks a paradigm shift in wireless communication, aiming to achieve unprecedented data rates, ultra-low latency, and massive connectivity. As the demand for high-speed and energy-efficient networks grows, Terahertz (THz) communications has emerged as a viable solution to address spectrum congestion and enhance wireless capacity. However, the implementation of THz communication presents challenges, including high path loss, signal attenuation, and energy efficiency concerns. To mitigate these limitations, Intelligent Reflecting Surfaces (IRS), Massive Multiple-Input Multiple-Output (MIMO), and advanced Internet of Things (IoT) architectures are being integrated into 6G frameworks to optimize performance. Intelligent Reflecting Surfaces (IRS) utilize reconfigurable metasurfaces to dynamically control signal propagation, improving coverage and mitigating path loss in high-frequency bands. Meanwhile, Massive MIMO enhances spectral efficiency and network robustness by leveraging large antenna arrays to enable precise beamforming and spatial multiplexing. Furthermore, energy-efficient IoT architectures are crucial in 6G networks to support ultra-low power, sustainable, and scalable communication for interconnected devices. These architectures leverage machine learning, edge computing, and blockchain technology to optimize resource allocation and reduce energy consumption. By combining IRS, MIMO, and advanced IoT architectures, 6G networks can harness the potential of THz communication while overcoming its limitations. This convergence will facilitate next-generation applications such as immersive extended reality (XR), autonomous systems, and ultra-reliable low-latency communications (URLLC). Future research should focus on seamless integration, security, and sustainability in 6G-enabled THz networks to achieve a truly intelligent and energy-efficient wireless ecosystem.

Authors: Triana-Vera Sonia , López-Vargas Omar
Published: February 2025

This research aimed to determine the effects of motivational scaffolding and adaptive scaffolding on academic and online self-efficacy in learners interacting with a multimedia learning environment within the field of technology. The study involved 146 students from four tenth-grade classes at a public institution in the municipality of Soacha (Cundinamarca-Colombia). The research followed a quasi-experimental design with two independent variables: (1) motivational scaffolding (static and faded by the student) and (2) adaptive scaffolding (fixed and differentiated), it also included two dependent variables; academic and online self-efficacy. A factorial MANCOVA statistical analysis showed a significant interaction of adaptive scaffolding and motivational scaffolding on self-efficacy for online learning. There was also evidence that differential adaptive scaffolding had a substantial effect on academic and online self-efficacy. These findings suggest that the use of motivational and differential pedagogical and/or didactic strategies in virtual learning environments, which integrate scaffolding faded by the student, enhances learners’ personal judgments about their abilities to learn content within the field of technology.
A Novel Solution to the Real-Time Lane Detection and Tracking Problem for Autonomous Vehicles by Using Faster R-CNN and Mask R-CNN
Authors: Ortataş Fatma Nur , Çetin Emrah
Published: February 2025

Autonomous vehicle technology has advanced in the automobile sector. Autonomous vehicle technology aims to make driving safer and reduce driver-caused traffic accidents. Autonomous driving technology work toward this. Lane detection and tracking are crucial to autonomous driving systems. Mostly the image processing techniques are mainly utilized for the lane detection in the literature. But, while performing image processing techniques for lane detection and tracking, two basic problems are mainly encountered. First one is image also needs to work with a specific area on the image to reduce the processing load and to work for the correct area. The region of interest (ROI) process is often used to filter the area to be worked from the image. However, since fixed coordinates are provided for this operation, the vehicle restricts the oper-ation of the vehicle in areas where it must be rotated. Second one is the weather conditions are very effective in the detection of lanes by utilizing image processing techniques. There are serious problems with image processing and detection from cloudy, sunny or momentary changes in the air. This study uses deep learning methods against these two basic problems. Using the Mask R-CNN and faster R-CNN algorithms together, these two basic problems for lane detection and tracking are eliminated and successfully implemented. The problem solved by two algorithms has been tested experimentally on a developed tool. Both the originally developed da-taset and the KITTI dataset were used separately in the model training carried out for the experimental tests. Both systems work well for lane detection and tracking, according to tests.

Intra-elite communication: collisions of ideological and narrative symbolization
Authors: Solovyev Aleksandr
Published: February 2025

Тhe central place of the ruling circles in the organization of the political order not only screens the influence of the civil sector on the distribution of public resources, but also turns intra-elite relations into the epicenter of the entire system of public administration. In contrast to the prevailing use of ideological symbolization tools in the public sphere, which allow managing discursive processes, in their internal relations, elite circles use narrative constructions that allow them to more accurately and quickly isolate the meanings of political messages of opponents at different levels, which are necessary to increase competitiveness, effective maneuvering, predict the prospects for their influence in the power structures, etc. Relying on the relevant cognitive and value-oriented structures of the group and individual consciousness of representatives of elite circles, political narratives not only encourage their communicative activity, contributing to the effective implementation of political and administrative functions, but also increase their distance from society and its interests. New divisions of elite strata preserve the prospect of their further autonomy, as well as an increase in the diversity of narratives used that influence the goals of state policy.
Evolution of the legislative assembly of St. Petersburg (1995–2007)
Authors: Sungurov Aleksandr
Published: February 2025

The evolution of the Legislative Assembly of St. Petersburg of the first three convocations (1995–2007) is considered, as well as briefly the activities of the Leningrad (after September 1991 — St. Petersburg) City Council of the XXI convocation (Lensovet). In these convocations, deputies were elected according to the majority system in 50 electoral districts. The most effective was the activity of the first convocation of the Legislative Assembly, which worked from the end of 1994 to the end of 1998. It was by the forces of the deputies of this convocation that the constitution of the city — subject of the Russian Federation was prepared and adopted — the Charter of St. Petersburg, which laid down the principles of separation and balance of powers, and also provided for the creation of the Statutory Court of St. Petersburg and the Institute of the Commissioner for Human Rights in St. Petersburg. This was achieved largely due to the high-quality composition of the Legislative Assembly, in which one third of deputies were deputies of the Leningrad City Council before that. As part of the activities of the Second Convocation of the Legislative Assembly (1999–2002), the law “On the Statutory Court of St. Petersburg” was adopted, and the Charter Court itself was elected. He made it possible to strengthen the system of checks and balances of the branches of regional government, and in his 2002 decisions, in particular, decided that the election of Governor V.A. Yakovlev for a third term would contradict the city Charter. During this period, the pressure of the executive power of St. Petersburg on deputies was partially offset by pressure from the Plenipotentiary Representative of the President of the Russian Federation. The third convocation (2003–2007) was characterized by a further strengthening of monocentrism and the emergence of the dominant faction of the United Russia Party. Under pressure from the Governor of St. Petersburg, deputies made serious amendments to the law “On the Statutory Court of St. Petersburg”, which significantly reduced its independence.
Social media in Russia: new forms of political participation. Main approaches (2010–2022)
Authors: Golbraih Vladimir

Over the past decades, significant changes have occurred in the daily life of people due to the emergence of social media. The use of social networks has become an everyday practice of Russian citizens, which has also affected the sociopolitical sphere. The use of social networks has become a daily practice of Russian citizens, which has also affected the socio-political sphere, which has caused increasing attention from domestic authors to this problem. The article is devoted to a review of Russian studies of this one of the most pressing problems. In domestic literature, the use of social media in conflicts caused by various problems is actively studied. Russian authors analyze new forms of political participation, new types of social movements, and the transformation of collective action. Some researchers believe that social media is being formed as a social institution. In this regard, we can talk about the process of institutionalization of new forms of political participation. At the same time, there are gaps in domestic studies: the influence of social media on political participation; organizations of social movements; transformation of collective action. In domestic literature, a critical look at social media is not visible, for example, the influence of the commercial and political component of social media. The growth of social media research provides confidence that new work will provide answers to a variety of still poorly understood aspects of political participation in social media.
Paradoxes of regional ethnopolitics in modern Russia
Authors: Achkasov Valeriy
Published: February 2025

The article examines some paradoxical features of regional ethnopolitics in modern Russia, which, according to the author, are explained by the fact that in modern Russia the ideological and institutional legacy of the Soviet national policy remains practically unchanged. This is primarily about the prevalence of the ethnocultural interpretation of the nation not only in society, but also in scientific and political discourse. Due to this, the political and intellectual elites of the “internal” Russian nations are very suspicious of the implementation of the goal declared in the “Strategy of the State National Policy of Russia until 2025” — the formation of a Russian civil nation, since they consider the processes of cultural assimilation as abnormal and dangerous for ethnic nations, and territory as a category of “national”, and in fact ethnic property. Based on the results of the study, the author formulates some recommendations regarding the necessary changes in the content of Russian ethnopolicy.
Cardinals of Europe and Africa: comparative analysis of the Catholic elite careers
Authors: Dmitrieva Valeriia
Published: February 2025

The article is intended to close the gap in the scientific literature on religious elites, associated with a lack of attention to the “Vatican bureaucracy” and a small number of comparative studies. The article offers an analysis of the biographies of European and African cardinals who are labeled as the Catholic elite according to the positional method. Geographic regions are selected based on the principle of least similarity. The career of cardinals is presented as a promotion through the church hierarchy, where the pre-elite stage is considered to be from ordination a priest to receiving episcopal ordination. The empirical basis of the study is data being gathered from the official website of the Holy See and processed in SPSS. The sample is equal to the general population and includes biographies of 137 hierarchs. The theoretical framework of the study is José Casanova’s concept of global Catholicism and Pierre Bourdieu’s sociology of religion. The analysis revealed that the careers of the Catholic elite of Europe and Africa, despite the presence of similar parameters, differ considerably. The rise of Europeans up the career ladder is accompanied by a decrease in endogeneity, understood as the coincidence of place of birth and work. This is due to the move to Rome, where dominant positions are concentrated and the “rules of the game” of the religious field are set. On the contrary, among Africans the type of career in which the prelate alternately occupies diocesan positions predominates. In the pre-cardinalate stage, African hierarchs are given leadership positions at the national level. This is due to the need to accumulate religious capital, which is not completed by the church in the African context. A comparative analysis of the biographies of the Catholic elite confirmed the hypothesis that regional differences have a significant impact on the careers of cardinals.
Global Financial Crisis (2007-2008) and Foreign Direct Investment (FDI) Inflows' Resilience to other Capital Flows in Sub-Sahara African (SSA) Countries
Authors: Ezebunwa Onu King
Published: February 2025

: This study examines the effect of global financial crisis (2007-2008) on foreign direct investment inflows' resilience to other capital flows to selected Sub-Sahara African (SSA) Countries. This study was motivated by the assertion that foreign direct investment (FDI) inflows to developing economies are resilient than other capital inflows in 2007-2008 global financial crisis that originated in developed world. Specifically, the study ascertained whether foreign direct investment (FDI) inflow is significantly resilient than foreign portfolio investment (FPI) inflow in SSA. Using panel datasets from 26 SSA countries, the study explored non-stationarity and heterogeneous – based dynamic panel estimators namely, Mean Group (MG) and Pooled Mean Group to empirically implement the objectives. The findings of the study amongst others revealed significant evidence of the resilience of the inflow of foreign direct investment to SSA during the global financial crisis period of (2007 – 2008), contrary to the wide-spread assertion that developing economies are immune to the impact of the crisis. Also, we found that the foreign direct investment (FDI) inflow is significantly resilient than foreign portfolio investment (FPI) inflows in SSA. This study recommends the policies that may stabilize growth of FDI inflows. Thus, more foreign investors should be attracted which should increase investment opportunities and growth in the region. Greater attention should be given to FDI whenever global financial crisis is experienced.
From latent constructs to networks: modeling high-dimensional social inferences in naturalistic settings
Authors: Lu Junsong , Lin Chujun
Published: February 2025

Long-standing research suggests that social inferences are captured by a few latent dimensions (e.g., warmth and competence). Others argue that social inferences are more complex but lack empirical support. Here, we conducted two pre-registered studies to test the high-dimensional properties of social inferences. To maximize generalizability, we computationally sampled diverse naturalistic videos and recruited U.S. representative participants (N = 1,598). Participants freely described people in videos using their own words. Cross-validation identified 25 latent dimensions which explained only 15% of the variance in the data. Alternatively, a sparse network model representing the unique correlations between inferences better represented the data. The network models informed the dynamics of naturalistic inferences, revealing how different inferences co-occurred and how they unfolded over time from concrete to abstract (Study 1). The network models also indicated cultural differences in how one inference was related to another between samples (Study 2, Asian N = 651, European N = 792). Together, these findings show that the high-dimensional network approach provides an alternative model for understanding the mental representation of social inferences in naturalistic contexts, which provides new insights into the dynamics and diversities of social inferences beyond the static, universal structure found with traditional low-dimensional latent-construct approaches.
