Bullying: a Study From the Perspective of Students With Disabilities

Objective: This research aims to delve deeper into the experiences and characteristics of bullying among students with disabilities. Theoretical Framework: Theories of social learning, social systems, and power imbalance help explain the underlying mechanisms of bullying in this context. Additionally, research has identified different roles of participation (victim, bully, bully-victim) and has highlighted the importance of disability characteristics in the experience of bullying. Method: Using a mixed-methods and naturalistic approach, surveys and interviews were conducted using the EBIPQ-SEND, a validated instrument for identifying involvement in bullying associated with special educational needs. The sample includes 15 students with disabilities aged 12 to 18. Results and Discussion: The results offer a perspective from the participants' voices on their understanding of the phenomenon, the types, roles, and consequences of bullying experienced by the group with disabilities. They invite us to strengthen the body of research that allows us to understand this harmful dynamic of school coexistence, in order to offer an effective response and promote educational inclusion. Implications of the Research: The implications of this research on bullying and disability are profound and multifaceted. By revealing the greater vulnerability of students with disabilities to bullying, this research highlights the urgent need to implement specific prevention and protection measures in educational settings. Originality/Value: The originality and value of this research lie in its contribution to shedding light on the issue of bullying towards students with disabilities, a group that has been historically underrepresented in studies on bullying.

Article title: Assessment of natural radioactivity (40K, 238U and 232Th) and radiological risk in building construction materials: the case of Benin hill granites

Continuous exposure to ionizing radiation can have harmful effects on human health. In this respect, a study was carried out in the Communes of Dassa-zoume and Glazoue to determine the levels of 40K, 238U and 232Th in granites and sand. The specific activities obtained made it possible to assess the possible radiological risks associated with the resident population. During sampling work in November 2022, twelve granite samples were taken from twelve quarries. In addition, a sand sample was collected in Cotonou for comparison. All samples were then sent to the INSTN-Madagascar laboratory for gamma-ray spectrometry analysis using a NaI(TI) detector. The results show that the average specific activities of 40K, 238U and 232Th in the granites are (1329 ± 128) Bq.kg-1, (44 ± 11) Bq.kg-1 and (129 ± 44) Bq.kg-1 respectively. Those in sand are (144 ± 8) Bq.kg-1, (30 ± 2) Bq.kg-1 and (56 ± 7) Bq.kg-1 respectively. The average equivalent radium activity is (330 ± 74) Bq.kg-1 versus (122 ± 10) Bq.kg-1 for sand. The mean gamma index for granite was (1.2 ± 0.3), compared with (0.43 ± 0.03) for sand. The average absorbed dose rate in air is (153.4 ± 9.4) nGy.h-1 versus (53.7 ± 5.1) nGy.h-1 for sand. For adults, for 80% building occupancy factor, the mean annual indoors and outdoors effective dose (E) inside a building are (0.75 ± 0.05) mSv.y-1 and (0.19 ± 0.01) mSv.y-1 versus (0.26 ± 0.05) mSv.y-1 and (0.07 ± 0.01) mSv.y-1 for sand. For 60% factor, the means are (0.56 ± 0.03) mSv.y-1 and (0.38 ± 0.02) mSv.y-1 versus (0.20 ± 0.01) and (0.13 ± 0.01) mSv.y-1 for sand. For the children, for a building occupancy factor of 80%, the average E are (0.86 ± 0.05) mSv.y-1 and (0.21 ± 0.01) mSv.y-1 versus (0.30 ± 0.01) mSv.y-1 and (0.08 ± 0.01) mSv.y-1 for sand respectively for indoors and outdoors. For infants, the E are (1.00 ± 0.06) mSv.y-1 and (0.25 ± 0.01) mSv.y-1 versus (0.35 ± 0.01) mSv.y-1 and (0.09 ± 0.01) mSv.y-1 for sand respectively for indoors and outdoors. For children, for a building occupancy factor of 60%, the average E are (0.64 ± 0.03) mSv.y-1 and (0.43 ± 0.02) mSv.y-1 versus (0.23 ± 0.01) mSv.y-1 and (0.15 ± 0.01) mSv.y-1 for sand respectively indoors and outdoors. For infants, for a building occupancy factor of 60%, the E are (0.75 ± 0.05) mSv.y-1 and (0.50 ± 0.02) mSv.y-1 versus (0.26 ± 0.01) mSv.y-1 and (0.18 ± 0.01) mSv.y-1 for sand respectively indoors and outdoors. For adults, the excess lifetime cancer risk at age 66 for a total annual effective dose induced by granite is (3.1 ± 0.01).10-3 versus (1.1 ± 0.01).10-3 for sand. For the children and infants, the average ELCR is (3.5 ± 0.01)E-3 and (4.1 ± 0.01)E-3 versus (1.2 ± 0.01)E-3 and (1.4 ± 0.01)E-3 for sand respectively. Statistical analysis of the data was performed with Python 3.11 and R 4.3.2 on the Spyder and studio interface. The p-value is < 0.001 compared with the UNSCEAR reference value for absorbed dose rate in air, effective dose and excess risk, which are 84 nGy.h-1, 0.48 mSv.y-1 and 0.29.10-3. This shows that the granites in the quarries studied present a radiological risk when used as building materials and need specific radiation protection measures for his users.

Forced evacuation as a mechanism of special protection measures for children during armed conflict

The article examines the compulsory evacuation of children by force (hereinafter - forced evacuation) as one of the preventive mechanisms for the implementation of special protection of children during armed conflict. This is a new mechanism introduced by the Ukrainian government in March 2023 with the aim of protecting children in the area of hostilities and armed conflicts under martial law. The authors of the article examine the procedure for making a decision on the forced evacuation of children from a particular settlement in an area where hostilities are taking place and the mechanism of its implementation. It is established that evacuation of children during armed conflicts has been implemented before. However, such evacuations were exclusively voluntary and often involved children unaccompanied by legal representatives. The ‘Ukrainian mechanism’ provides for the forced evacuation of children and must be accompanied by one of their legal representatives. The authors note that this mechanism has been approved at the level of the Ukrainian government (the Parliament has not yet adopted any legislative acts). A comparative analysis of the peculiarities of the legal status of a child under international and national legal acts is carried out to take into account the scope of the child's rights and obligations during evacuation. The article concludes that the forced evacuation of children during armed conflict is a necessary preventive mechanism to provide protection to the most vulnerable category of civilians. At the same time, the authors focus on the existing shortcomings which require further regulatory regulation. The purpose of the article is to provide a legal analysis of the evacuation of children during armed conflict at the level of international legal instruments and at the national level, and its specific features established in Ukrainian legislation. The methodological basis of the study are the method of systematic approach, the method of descriptive analysis, the formal legal method and the method of comparative forecasting.

Metaverse risks and harms among US youth: Experiences, gender differences, and prevention and response measures

Research indicates that participation in metaverse environments and with virtual reality (VR) is increasing among younger populations, and that youth may be the primary drivers of widespread adoption of these technologies. This will more readily happen if their experiences are safe, secure, and positive. We analyze data from a nationally representative sample of 5005, 13- to 17-year-olds in the United States to measure their experiences of 12 specific harms on VR platforms, and which protective strategies they employed to prevent or respond to them. Girls were more likely to be sexually harassed and to experience grooming/predatory behavior, and were more likely to have been targeted specifically because of their gender. Finally, girls were more likely to engage in some specific protective measures online, but overall both boys and girls use platform safety mechanisms infrequently. We discuss enhancements in policy, content moderation, and feature sets that can serve to better safeguard youth in the metaverse.

The specifics оf тhe development оf soil flushing during spring snowmelt in the arable land of the northern zone of the Krasnoyarsk forest-steppe

The results of studies of soil flushing and accumulation in the period 2009–2017 in the northern part of the Krasnoyarsk forest-steppe in areas with high intensity of erosive and accumulative processes are presented. A wide range of erosion values from meltwater has been established – from 0.4 to 25 mm for the spring period. The results of the application of a refined Regional model for calculating potential flushing for the northern part of the Krasnoyarsk forest-steppe are presented. The analysis of meteorological factors and conditions of the underlying surface affecting the distribution of values of melt runoff, flushing and accumulation of soils on arable massifs located on inclined watershed surfaces is carried out: the specificity of the distribution of meltwater flows determines the formation of zones of extreme erosion along the perimeter of arable land in the lower parts of the slope – up to 15–20 mm of soil layer. In conditions of low slope steepness, the effect of relief on erosion is largely determined by the high slope lengths and melt water flow lines. The distribution of flushing values over the area of arable land shows a close correlation with the values of snow accumulation and soil moisture. The spatial and temporal patterns of the influence of the previous autumn soil moisture on the intensity of erosion have been established: the values of flushing increase with increasing soil moisture, the average values of erosion correlate with the values of autumn soil moisture in dynamics over the years of field observations. Special soil protection measures have been proposed for sites with the most intensive flushing in the research area.

Ethical Considerations of Including Minors in Clinical Trials Using the Example of the Indicated Prevention of Psychotic Disorders

Ethical Considerations of Including Minors in Clinical Trials Using the Example of the Indicated Prevention of Psychotic Disorders Abstract: As a vulnerable group, minors require special protection in studies. For this reason, researchers are often reluctant to initiate studies, and ethics committees are reluctant to authorize such studies. This often excludes minors from participating in clinical studies. This exclusion can lead to researchers and clinicians receiving only incomplete data or having to rely on adult-based findings in the treatment of minors. Using the example of the study "Computer-Assisted Risk Evaluation in the Early Detection of Psychotic Disorders" (CARE), which was conducted as an 'other clinical investigation' according to the Medical Device Regulation, we present a line of argumentation for the inclusion of minors which weighs the ethical principles of nonmaleficence (especially regarding possible stigmatization), beneficence, autonomy, and fairness. We show the necessity of including minors based on the development-specific differences in diagnostics and early intervention. Further, we present specific protective measures. This argumentation can also be transferred to other disorders with the onset in childhood and adolescence and thus help to avoid excluding minors from appropriate evidence-based care because of insufficient studies.

A Protocol of Prevention and Protection Measures on New Occupational Risk Factors in Green Jobs in Italian Workplaces

The Green Transition aims to protect the health of our planet through changes at the economic, political, and social levels while also having a significant impact on the world of work through the creation of sustainable occupations, referred to as ‘Green Jobs’. The aim of our research was to identify the new emerging occupational risks associated with Green Jobs and to propose a protocol to promote the adoption of more appropriate prevention and protection measures. Starting with a few keywords chosen by the authors, we conducted a narrative review of the scientific articles published in the literature. The results obtained show that the new occupational risks emerging in the activities involved in the green transition are mainly related to the introduction of new materials or new technologies and to modes of production processes. These risks may pose a danger to those exposed to them on a daily basis, causing damage to health. Our protocol proposal calls for a more careful and adequate risk assessment for Green Jobs, providing specific training on these issues for new professionals in the sector and introducing specific prevention and protection measures for the different occupational risks analysed in the workplace. By adopting these recommendations in the workplace and conducting in-depth research on these issues, it will be possible to contribute to the improvement of prevention and protection for these new emerging occupational risks, achieving a positive economic impact and better safety conditions for workers.

Identification of key areas for ecological restoration of territorial space based on ecological security pattern analysis: A case study of the Taihu Lake city cluster.

The identification of key areas for ecological restoration of national land space based on the ecological security pattern is an important way to balance environmental protection and social development in the new era. With the Taihu Lake city cluster as the study area, we identified the ecological source from both structural and functional aspects, and used the minimum cumulative resistance model to identify the ecological corridors on the basis of constructing the resistance surface. Coupled the landscape ecological risk evaluation, we determined the appropriate width of each ecological corridor in the study area, identified the key restoration zones through the circuit theory. Then, we constructed the ecological security pattern of "six zones and four belts" and controlled by zoning. The results showed that the 32 ecological source areas in the Taihu Lake city cluster presented a spatial pattern of "more in the east and less in the west-mountains and lakes are connected" and 70 ecological corridors were concentrated in the west and the center. The suitable width of most of the ecological corridors was 1500-2000 m. The ecological restoration zones of the national land space were concentrated in the eastern part of the Lake Taihu, Changxing County, and Liyang City. According to the characteristics of the study area and the actual situation of the restoration area, we proposed specific protection and restoration measures, such as protecting the core ecological source, optimizing and restoring the important corridors, and reasonably planning land use of the ecological pinch points and obstacle points.

Enhanced Carbon Accumulation in China's New Coastal Wetlands Over the 21st Century

AbstractWetlands formed by natural sediment deposition account for a large proportion of new coastal lands, and these new wetlands usually have active ecosystems and obvious ecological effects. However, previous studies largely overlooked this sediment‐caused wetland expansion, and the spatiotemporal variation in these wetlands and future response to sea‐level rise (SLR) have not been determined. Here, we employed satellite observations to quantify the seaward expansion of coastal lands in China over the past two decades. A total land expansion of 6,651 km2 was found, and wetlands and artificial surfaces dominated, accounting for 32% and 25%, respectively. Subsequently, we utilized an integrated model to estimate the response of these new wetlands to SLR in the 21st century, that is, we estimated the wetland gain from sediment deposition and loss due to SLR. The results indicate that under the current condition of sediment availability, the area of China's new coastal wetlands is projected to increase by 200%–261% compared to that in 2020 based on four SLR scenarios, despite the unavoidable impact of SLR. These increases are accompanied by the continuous enhancement of carbon accumulation. Wetland changes are influenced by factors such as sediment deposition, SLR and storm surges, as well as the continued effect of local natural and anthropogenic factors. These results show the importance of understanding the ecological effects of new wetlands and constructing specific protection measures for sustainable development.

Analysis of fire protection design strategies for commercial renovation of villagers’ self-built houses

Abstract The current situation of self-built houses by villagers is prevalent in rural areas, where many villagers construct their own residential dwellings based on their personal needs and economic circumstances. These self-built houses are typically constructed using basic materials and traditional building techniques, often without adherence to strict building regulations and standards. As a result of the lack of professional knowledge and technical guidance, the structural integrity and safety of these houses are often compromised. In addition, the lack of firefighting facilities and fire prevention measures further increase the risk of fire accidents. This situation contributes to a higher incidence of fires in rural areas, posing a significant threat to the lives and assets of villagers. Therefore, it becomes imperative to improve the current state of self-built houses by villagers. Strengthening fire safety awareness and implementing robust fire prevention measures are vital in this regard. This paper aims to summarize the challenges involved in fire protection design for renovating rural buildings. Additionally, it proposes fire protection design principles specifically for the commercial transformation of self-built houses by villagers. By analyzing real-world engineering cases, this study puts forth specific fire protection measures concerning fire rescue, fire control zones (groups), evacuation design, and fire systems. To ensure the fire safety of these buildings, special fire protection design methods are employed. The effectiveness of the proposed fire protection measures are validated through the use of FDS fire and smoke numerical simulation analysis software and Pathfinder evacuation simulation software, ensuring the fire safety of the buildings. The results show that the available safe evacuation time that can be provided by this scenario is 1200 s as calculated by the FDS simulation, and the necessary safe evacuation time is less than the available safe evacuation time in case of a fire on the first floor of this building, and the safe evacuation of the people can be guaranteed. This study can provide a valuable resource for architects, engineers, and decision makers to implement effective fire protection measures during commercial remodeling of village-owned houses.

A re-conceptualisation of the Batwa's right to recognition as a minority and indigenous people in Rwanda: A human rights-based approach

There have been divergent views by various human rights scholars and actors on how to address the question of vulnerability among indigenous and minority groups in Rwanda. Even though factors influencing vulnerability among these groups have received increasing scholarly attention, findings from these studies fall short of reflecting on the role of identity and discrimination. Whereas the government in Rwanda after the 1994 genocide sought to enhance unity and reconciliation by outlawing all ethnic identities, and instead conflating all vulnerable groups into a nomenclature namely, a Historically Marginalised People (HMP), a divergent group of scholars, human rights activists, the United Nations and African Union's instruments of human rights describe this approach as antithetical to the promotion and protection of the rights of indigenous and minority groups. Using the human rights-based approach, this paper critically interrogates the issue of identity and how it has affected the enjoyment of the rights among the minority and indigenous Batwa people in Rwanda.The study employed a qualitative research design with data collected through Focus Group Discussions (FGDs) as well as in-depth interviews (IDIs). Respondents included members of the Batwa community, officials of selected public institutions, leaders in Non-Governmental Organisations (NGOs), and cooperative societies working towards the promotion of rights of the HMP. Data analysis involved the process of transcription and coding of data and the eventual reflexive thematic analysis.The findings show that the rights of the Batwa community to recognition and self-identity have varied meanings and implications to different members of the community as well as officials from public institutions and other relevant actors. To the existing research, the study affirms that the inconsistencies surrounding the Batwa's identity have accentuated their vulnerability.In terms of policy, the study suggests that in the short run, the Batwa community may require enhanced special temporary social protection measures in order to ameliorate their conundrum arising from identity ambiguity without compromising Rwanda's national unity. Further studies, should consider the role of land, forest and culture in further marginalising the Batwa, as well as quantitative methodology for inferential analysis.

Heat literacy and adaptation among semi-rural community in Malaysia

BackgroundHeatwaves present health risks globally but there is limited evidence on how temperature perceptions affect activities. This study aimed to examine community perceptions of heat as a potential health hazard and ascertain the current heat protection measures of the residents of the South East Asia Community Observatory (SEACO) in Malaysia. MethodsIn this longitudinal study, we randomly selected community members aged between 18 and 70 years who resided in Segamat district of Johor state, Malaysia. Over 21 days, we conducted three home visits to each participant. During each visit, participants completed a questionnaire consisting of Likert scale, multiple choice, and free text questions and we collected quantitative and qualitative data. These inquiries assessed the participants' perception of heat as health threat, whether or not they took heat preventive measures, and the specific protective measures they routinely employed. Descriptive data analyses were conducted and patterns of protective measures were investigated. FindingsBetween March 29 and July 31, 2023, 120 participants (72 women and 48 men) completed 360 questionnaires over three home visits. Initially, 58% participants recognised heat hazards to daily activities, decreasing to 42% and 35% by visits 2 and 3. Participants took preventive measures throughout the day, which was consistently high between 1200 h and 1400 h, with 77% of participants taking preventive measures on visit 1, 82% on visit 2, and 82% on visit 3. Use of preventive measures was also high between 1400 h and 1730 h, with 77% using preventive measure on visit 1, 81% on visit 2, and 79% on visit 3. The most common protective measures were fans (used by 68–88% of participants), drinking more water (70–78% of participants), and resting (44–72% of participants). The least common were relocating to cooler places, removing clothes, and using wet towels (0–2·5%). Despite high temperatures, perceptions of heat risks decreased over time. Participants took basic protections, especially at midday, but improved literacy and affordable cooling options are needed to protect vulnerable rural populations. InterpretationOur findings underline the need to improve heat literacy and adaptation as only half of the population assessed perceived heat as a potential health hazard and practised limited heat protective measures. Addressing climate change and health necessitates fundamental behavioural changes on the part of individuals and communities, to protect them against the adverse effects of heat.

Assessing and improving radiation safety in cardiac catheterization: a study from Cairo University Hospital

BackgroundCatheter laboratories are high-radiation exposure environments, especially during X-ray procedures like percutaneous transluminal coronary angioplasty and electrophysiological studies. Radiation exposure poses risks of stochastic (e.g., cancer) and deterministic (e.g., skin changes) effects. This study assessed radiation safety and health practices in a cardiac catheterization unit to optimize radiation safety. A cross-sectional study in Cairo University Hospital (March–September 2019) evaluated 700 patients and healthcare workers. Real-time radiation measurements, educational lectures, and radiation protection measures were implemented in three phases. Data on radiation exposure, procedures, and compliance were collected and analyzed.ResultsThe total procedure time and fluoroscopy time per cardiologist did not significantly differ between phases, but there was a statistically significant reduction in the mean total cumulative radiation doses between Phase I and Phase III for cardiologists (P = 0.013). Among nurses and technicians, there was no significant difference in radiation doses between the two phases. Significant correlations were found between operators' radiation doses, procedure time, and fluoroscopy time. Patients' radiation doses decreased significantly from Phase I to Phase III, with correlations between dose, procedure time, and gender. Compliance with radiation protection measures was suboptimal.ConclusionsCompliance with radiation safety standards in the cardiac catheterization unit at the Cairo University Hospital needs improvement. The study highlights the importance of adhering to radiation safety principles and optimizing protective measures to reduce radiation exposure for both patients and healthcare personnel. Despite low compliance, significant reductions in radiation doses were achieved with increased awareness and adherence to specific protection measures. Future efforts should focus on enhancing radiation safety protocols and organ-specific radiation impact assessments.

Movements and spatial distribution of an endangered fish (Sciaena umbra) within a marine protected area

The brown meagre (Sciaena umbra) is an endangered species, which requires specific protection measures to ensure its conservation. These measures need to be informed by high-quality scientific knowledge on their space use patterns. Here, we used acoustic telemetry to assess its seasonal movement patterns and habitat use within a marine protected area (MPA). Our results suggested that S. umbra is a highly sedentary species (home range < 1.0 km2) and, therefore, the MPA is extensive enough to protect the local population. Their population was discretely distributed in two main areas within the MPA, which was likely a result of habitat segregation and density-dependent movements. The temporal variability of their movements further uncovered when and where spawning occurs (mainly, but probably not only, in the fully protected area in June) and indicated that spillover of this species is limited but still possible. Overall, we highlight the importance of MPAs in the recovery of S. umbra, we advocate the need to perpetuate the current national fishing bans and extend it to other countries in the Mediterranean region, and we emphasize that considering the fine-scale movements of S. umbra in future management actions is key to achieving a successful recovery of their populations.

Faktor yang Berhubungan dengan Penerimaan Vaksin HPV

ABSTRACT Background of Study: Cervical cancer prevention will be more effective if accompanied by specific protective measures such as HPV immunization. A preliminary study conducted on May 28, 2022, on ten seventh grade students of Ma'Arif Sukaraja Junior High School found that 30% of parents refused the vaccine due to concerns related to its permissibility. The aim of this study was to identify factors associated with HPV vaccine acceptance by parents at Ma'Arif Sukaraja Junior High School in 2022. Methods: The research design used was analytic observational with a cross-sectional design. The population in this study consisted of all parents of Ma'Arif Sukaraja Junior High School students, totaling 58 people. The study used the total sampling method with all 58 individuals as samples. Data collection was done by distributing questionnaires to students, which were then taken home to be filled in by their parents. Results: About 46.66% of parents refused the HPV vaccine, with the most common reason for refusal being distrust of the vaccine (42.66%). The chi-square test showed a significant association between poor parental knowledge of HPV vaccine (PR: 3.04; p value: 0.01) and history of cancer infection (PR: 0.02; p value: 0.01). Logistic regression analysis showed that the factor that most influenced HPV vaccine acceptance at Ma'Arif Sukaraja Junior High School in 2022 was poor parental knowledge about the HPV vaccine (PR: 12.98; p value: 0.01). Conclusion: The most influential variable in HPV vaccine acceptance at Ma'Arif Sukaraja Junior High School in 2022 is poor parental knowledge about the HPV vaccine. Keywords: HPV, Vaccine Acceptance, Parents

The main problem revealed for the field development is a high water cutting of well production that made necessary to systematically carrying out a number of geological and technical measures. The most effective measures used to stabilize and increase oil production are highlighted. In order to meet the established environmental standards during the development of the deposit, proposals for the application of the specific environmental protection measures have been introduced.

Identifying the interplay between protective measures and settings on the SARS-CoV-2 transmission using a Bayesian network.

Contact tracing played a crucial role in minimizing the onward dissemination of Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) in the recent pandemic. Previous studies had also shown the effectiveness of preventive measures such as mask-wearing, physical distancing, and exposure duration in reducing SARS-CoV-2 transmission. However, there is still a lack of understanding regarding the impact of various exposure settings on the spread of SARS-CoV-2 within the community, as well as the most effective preventive measures, considering the preventive measures adherence in different daily scenarios. We aimed to evaluate the effect of individual protective measures and exposure settings on the community transmission of SARS-CoV-2. Additionally, we aimed to investigate the interaction between different exposure settings and preventive measures in relation to such SARS-CoV-2 transmission. Routine SARS-CoV-2 contact tracing information was supplemented with additional data on individual measures and exposure settings collected from index patients and their close contacts. We used a case-control study design, where close contacts with a positive test for SARS-CoV-2 were classified as cases, and those with negative results classified as controls. We used the data collected from the case-control study to construct a Bayesian network (BN). BNs enable predictions for new scenarios when hypothetical information is introduced, making them particularly valuable in epidemiological studies. Our results showed that ventilation and time of exposure were the main factors for SARS-CoV-2 transmission. In long time exposure, ventilation was the most effective factor in reducing SARS-CoV-2, while masks and physical distance had on the other hand a minimal effect in this ventilation spaces. However, face masks and physical distance did reduce the risk in enclosed and unventilated spaces. Distance did not reduce the risk of infection when close contacts wore a mask. Home exposure presented a higher risk of SARS-CoV-2 transmission, and any preventive measures posed a similar risk across all exposure settings analyzed. Bayesian network analysis can assist decision-makers in refining public health campaigns, prioritizing resources for individuals at higher risk, and offering personalized guidance on specific protective measures tailored to different settings or environments.

NephroCAGE-German-Canadian Consortium on AI for Improved Kidney Transplantation Outcome: Protocol for an Algorithm Development and Validation Study.

Recent advances in hardware and software enabled the use of artificial intelligence (AI) algorithms for analysis of complex data in a wide range of daily-life use cases. We aim to explore the benefits of applying AI to a specific use case in transplant nephrology: risk prediction for severe posttransplant events. For the first time, we combine multinational real-world transplant data, which require specific legal and technical protection measures. The German-Canadian NephroCAGE consortium aims to develop and evaluate specific processes, software tools, and methods to (1) combine transplant data of more than 8000 cases over the past decades from leading transplant centers in Germany and Canada, (2) implement specific measures to protect sensitive transplant data, and (3) use multinational data as a foundation for developing high-quality prognostic AI models. To protect sensitive transplant data addressing the first and second objectives, we aim to implement a decentralized NephroCAGE federated learning infrastructure upon a private blockchain. Our NephroCAGE federated learning infrastructure enables a switch of paradigms: instead of pooling sensitive data into a central database for analysis, it enables the transfer of clinical prediction models (CPMs) to clinical sites for local data analyses. Thus, sensitive transplant data reside protected in their original sites while the comparable small algorithms are exchanged instead. For our third objective, we will compare the performance of selected AI algorithms, for example, random forest and extreme gradient boosting, as foundation for CPMs to predict severe short- and long-term posttransplant risks, for example, graft failure or mortality. The CPMs will be trained on donor and recipient data from retrospective cohorts of kidney transplant patients. We have received initial funding for NephroCAGE in February 2021. All clinical partners have applied for and received ethics approval as of 2022. The process of exploration of clinical transplant database for variable extraction has started at all the centers in 2022. In total, 8120 patient records have been retrieved as of August 2023. The development and validation of CPMs is ongoing as of 2023. For the first time, we will (1) combine kidney transplant data from nephrology centers in Germany and Canada, (2) implement federated learning as a foundation to use such real-world transplant data as a basis for the training of CPMs in a privacy-preserving way, and (3) develop a learning software system to investigate population specifics, for example, to understand population heterogeneity, treatment specificities, and individual impact on selected posttransplant outcomes.

Forecast of changes in the beach condition of the Yuzhne city under the influence natural factors

The study of the factors of degradation and the forecast of the state of recreational areas of the coast to prevent their negative changes is relevant. Purpose. Forecast of changes in the condition of the Yuzhne beach, provision of general proposals for its protection from degradation. Methods. Mathematical statistics, linear analysis and mathematical modeling, comparative analysis, cartographic and grapho-analytical studies. Results. The beach of Yuzhne is located on the coast of the Black Sea. Its length is approximately 700 m. The southern direction in the sector 180±22.5⁰ is dangerous for waves. The distance from the beach to the opposite shore (wave acceleration) is 540-610 km. The boundary between the shallow and deep water zones is at a distance of approximately 200 km with a depth of 75 m. With southerly winds, recurring once every 25 years, on the approach to the shallow water zone with a depth of 50-75 m, a developed disturbance with extreme wave parameters is formed, which, transforming in the shallow water zone, significantly affects the coast. A profile of relative dynamic equilibrium with a length of 1,200 m and a depth at this distance of 11.2 m is formed during the calculated disturbance. From the water cut, the boundary between the near-cut and surf zones is located at a distance of 220 m with a depth of 3.6 m. Regardless of the standing water level, the calculated storm destroys the original shore at the extreme parts of the beach. When the sea level is high, the disturbance moves the destroyed material with the beach material into the cut-off zone, while the water cut at the 0.0 m BS mark does not change its planned location. The amount of beach material on the upper part of the coastal slope may decrease significantly. At an average level of the sea, the washing away of destroyed and beach material is accompanied by the advance of the water cut toward the sea for a distance of up to 20 m, but at the same time, a decrease in beach material on the above-water part of the coastal slope is also observed. Conclusion. Without taking special protection measures, the beach of the Yuzhne city will degrade in the future. In areas of the beach, in order to prevent its erosion, it is necessary to erect a retaining wall with a backfilling layer. An option for an active method of protection can be the construction of permeable bunkers on the beach or an intermittent breakwater at a distance from the shore. Such protection will not impede the alongshore transport of sand. Dunes or waves will contribute to the accumulation of sand on the beach. At the same time, after strong storms from the southern direction, with high sea level, episodic additions of sand to the beach are necessary

Factors affecting individual beliefs associated with the quality of life of traditional divers in the coastal area

Traditional divers in Surabaya’s coastal area face challenges despite the abundance of marine resources. This study aims to explore the factors that related to the quality of life among these divers. The research followed an observational analytic approach with a cross-sectional design. The study involved 31 traditional divers from Kedung Cowek Village in Surabaya, randomly selected based on specific criteria. The research utilised the Health Belief Model theory to assess individual beliefs and the WHOQOL-BREF tool to measure their quality of life. The individual beliefs were categorised into five indicators: perceived vulnerability, perceived severity, perceived obstacles, perceived benefits, and self-efficacy. Out of these factors, two had a significant influence on the quality of life of traditional divers: perceived benefits (p = 0.009) and self-efficacy (p = 0.020). The study concludes that the quality of life for traditional divers in the Surabaya coastal area is primarily influenced by perceived benefits and self-efficacy. It suggests that nearby healthcare facilities could offer health education to traditional divers, focusing on specific protective measures to reduce the risks associated with diving, such as barotrauma and decompression sickness.
