Recent climate changes have led to an increase in flood intensity, often resulting in frequent levee overtopping, which causes significant human and property damage. High vulnerability to such breaches is expected in general, especially at river curves. This study aims to predict the occurrence of levee overtopping at these critical points and to suggest a curve, the levee overtopping risk curve, to assess overtopping probabilities. For this purpose, several dimensionless parameters, such as superelevation relative to levee height ($∆$y/H) and the channel’s Froude number, were examined. Based on dimensional analysis, a relationship was developed, and the levee overtopping curve was finally proposed. The accuracy of this curve was validated through numerical analysis using a selected levee case, which clearly distinguished between safe and risky conditions for levee overtopping. The curve is designed for immediate integration into the hydraulic design processes, providing engineers with a reliable method for optimizing levee design to mitigate overtopping risks. It also serves as a critical decision-making tool in flood risk management, particularly for urban planning and infrastructure development in areas prone to flooding. Full article

Urban development through property development in central parts of cities rather than through sprawl is key to achieving sustainable future cities. However, realising desired projects in complex city centre environments is challenging and risky due to the involvement of numerous actors. This paper offers novel insights into developers’ perspectives on how the conduct of public authorities influences city centre zoning plan processes. Based on interviews with 11 employees of property development firms, working on mixed-use city centre projects ranging from 1100 to 112,000 m² Gross Floor Area in small and medium-sized Norwegian cities, the study identifies key challenges developers experience in their interactions with public authorities across sectors and administrative levels during planning processes and analyses how these challenges relate to goals, knowledge and power among key actors. The study finds that public authorities can improve the efficiency of zoning plan processes and enhance city centre project delivery by altering their conduct. First, by more explicitly clarifying that the realisation of desired city centre property developments is a primary policy objective, maintaining this focus throughout the processes and taking responsibility for reconciling conflicts in ways that enable feasible projects. Second, by improving their knowledge of the fundamental need for projects to be profitable in order to be realised, and the impact of authorities’ requirements on project viability. Third, by exercising their agenda-setting power more constructively and flexibly throughout the zoning plan process. The paper examines underexplored perspectives in planning research and yields actionable recommendations for planning practice. Full article

Background: This study explored how health professionals construct clinical and psychological meaning based on the location of self-injury on the body, particularly in relation to concealed or visible injuries and how they might inform attributions about risk, self-injury functions, and distress. Methods: This study used qualitative thematic analysis of semi-structured interviews with 19 health professionals with experience working with self-injury, exploring perceptions and attributions about self-injury in different body locations. Results: Seven themes emerged. In some cases, staff’s attributions aligned with the findings from studies of those who self-injure, such as injuries to areas such as the neck are higher risk. Location was one factor among others, such as injury severity, that staff considered when assessing the risk of infection or suicide. Staff often viewed visible injuries as less risky and attributed them to interpersonal communicative functions, and concealed injuries to intrapersonal factors, though not all staff shared these perspectives. Some staff considered other potential drivers of injury location, including past experiences such as trauma, demographic factors, mental health diagnoses, and exposure to social influences. Some staff described the practical determinants of injury location, such as ease of access, and considered the impact of self-injury location on themselves and their colleagues. Conclusions: Injury location can influence staff perceptions of risk, self-injury functions and distress, underscoring the need for individualized assessment and formulation of each self-injury episode to ensure appropriate risk management. Staff training should be adapted to address injury location to improve understanding, raise awareness of related attributions, and enhance the development of clinical skills. Organizations should support staff in their role due to the potential emotional impact of working with individuals who self-injure and are at risk of suicide. Future research should investigate whether location-based attributions are associated with unintended clinical consequences, such as inaccuracies in risk assessment and formulation. Full article

Background: The current study explores the relationship between children’s risk willingness and their motor behavior in a virtual playground setting and its association with perceived gross motor competence. Methods: A total of 96 children aged seven to ten participated. They were categorized into high-risk-willingness (HRW) and low-risk-willingness (LRW) groups based on their exploratory behavior and engagement with riskier zones and tasks in the playground. Using whole-body motion capture and virtual reality data, the children’s motor behavior and variability were analyzed alongside self-reported perceived gross motor competence. Results: The results indicated that HRW children displayed significantly greater movement variability, including higher joint movement variability and increased exploration of challenging areas compared to LRW children. HRW children also covered greater distances, moved faster, and exhibited more frequent acceleration changes. Conclusions: These findings suggest that higher risk willingness is associated with greater adaptability and flexibility in motor behavior, aligned with the concept of freeing degrees of freedom. In contrast, no significant differences were found in perceived gross motor competence ratings between HRW and LRW groups. This indicates that perceived motor competence may not directly influence children’s willingness to take risks or their motor behavior in exploratory play. These findings emphasize the importance of studying dynamic interactions between risk-taking, motor behavior, and self-perception to understand the development of adaptive motor skills through risky play.

Challenge, adventure, and risky play have repeatedly been found to be learning environments that positively shape childhood well-being and development. Extant evidence-based research conveys the physical, cognitive, and socio-emotional growth associated with risky play provision. However, understanding the interplay of risky play, injury, and safety is more nuanced and complex. The goal of this paper is to introduce a tool which allows educators, parents, health practitioners, urban planners, playground designers, certifiers, manufacturers, and inspectors to estimate both the benefit and risk of outdoor play and learning settings, such as playgrounds, adventure parks, or risk-taking activities. One of the key challenges associated with societal risk appetite or risk tolerance has been the inability to quantify the inherent benefits of risk taking in playgrounds and educational settings. Historically, the assessment of ‘benefit–risk’ has been dominated by a zero tolerance of incidents, whether in the workplace or road safety settings. Against this backdrop, if playgrounds and outdoor learning settings are boring, children will go elsewhere to seek thrills and adventure, which may often be manifested in antisocial behaviour. In 2023, ‘benefit–risk’ was formally recognised in the area of sport and recreation by the International Organisation for Standardisation, when it published the ISO 4980:2023 benefit–risk assessment for sport and recreational facilities, activities, and equipment. ISO 4980:2023 is a departure from the traditional view of risk management, in that it presents a perspective of risk which is not limited to framing risk as negative, but rather balances the calculation of positive benefits as well as the risks associated with the activity. Correspondingly, hazardous situations which have zero benefit should be eliminated or mitigated. The tool introduced in this paper offers playground inspectors and educators the ability to measure and assess both the benefit and risk of outdoor playgrounds and educational settings where children play, learn, and flourish.

The Middle Yangtze River Urban Agglomeration, a critical ecological barrier in China, faces escalating pressures from rapid urbanization and climate change, leading to fragmented landscapes and degraded ecosystem services. To address the synergistic challenges of ecological protection and risk management, this paper takes the urban agglomeration in the middle reaches of the Yangtze River as the study area, and obtains the source patches through morphological spatial pattern analysis. Based on the spatial distribution of risky source areas, ecological blind zones are cut down by optimizing buffer zones and merging fragmented patches. Finally, a composite ecological network is constructed through circuit theory superimposed on the dual network method. The results showed that (1) there are 16 ecological source patches and 16 risk source patches in the study area. Six complementary ecological sources and four new ecological sources were obtained through the blind zone reduction strategy. The percentage of ecological blind zones reduced from 58.4% to 39.5%. (2) The integrated nodes with 11,366 connecting edges were identified. The integrated nodes are distributed around the central Jiuling-Mafushan Mountains, mainly in the western and southern areas of the Dongting Lake Plain. (3) Primary integration nodes are critical for network stability, with a 75% node failure threshold triggering systemic collapse. The proposed strategy of “mountain protection–plain control–railway monitoring” is consistent with China’s territorial and spatial planning. By incorporating the risk network into the conservation framework, this study provides feasible insights for balancing development and sustainability in ecologically fragile areas. Full article

The trematodes Fasciola hepatica and F. gigantica are transmitted by lymnaeid snails and cause fascioliasis in livestock and humans. Human infection is emerging in southern and southeastern Asia. In India, the number of case reports has increased since 1993. This multidisciplinary study analyzes the epidemiological scenario of human infection. The study reviews the total of 55 fascioliasis patients, their characteristics, and geographical distribution. Causes underlying this emergence are assessed by analyzing (i) the climate change suffered by India based on 40-year-data from meteorological stations, and (ii) the geographical fascioliasis hotspots according to archeological–historical records about thousands of years of pack animal movements. The review suggests frequent misdiagnosis of the wide lowland-distributed F. gigantica with F. hepatica and emphasizes the need to obtain anamnesic information about the locality of residence and the infection source. Prevalence appears to be higher in females and in the 30–40-year age group. The time elapsed between symptom onset and diagnosis varied from 10 days to 5 years (mean 9.2 months). Infection was diagnosed by egg finding (in 12 cases), adult finding (28), serology (3), and clinics and image techniques (12). Climate diagrams and the Wb-bs forecast index show higher temperatures favoring the warm condition-preferring main snail vector Radix luteola and a precipitation increase due to fewer rainy days but more days of extreme rainfall, leading to increasing surface water availability and favoring fascioliasis transmission. Climate trends indicate a risk of future increasing fascioliasis emergence, including a seasonal infection risk from June–July to October–November. Geographical zones of high human infection risk defined by archeological–historical analyses concern: (i) the Indo-Gangetic Plains and corridors used by the old Grand Trunk Road and Daksinapatha Road, (ii) northern mountainous areas by connections with the Silk Road and Tea-Horse Road, and (iii) the hinterlands of western and eastern seaport cities involved in the past Maritime Silk Road. Routes and nodes are illustrated, all transhumant–nomadic–pastoralist groups are detailed, and livestock prevalences per state are given. A baseline defining areas and seasons of high infection risk is established for the first time in India. This is henceforth expected to be helpful for physicians, prevention measures, control initiatives, and recommendations for health administration officers. Full article

Antibiotic resistance is a major problem worldwide, especially with the overuse and misuse of antibiotics. This makes it more challenging to treat patients infected with antibiotic-resistant bacteria, with more costs on the health system. This review article describes extended-spectrum β-lactam antibiotics as the most used antibacterial agents, and how bacteria developed beta-lactamases (ESBLs) to resist these antibiotics. The review focuses more on the problem of ESBLs in Kuwait to uncover which ESBLs are present and what ESBL gene mutations have been found in this country. The literature review, surprisingly, revealed a limited number of studies in Kuwait on ESBL gene mutations, published over the last 25 years. The results showed that Kuwait has an alarming number of bacterial strains with ESBL gene mutations. These studies reported different mutations in different bacterial strains isolated from different types of specimens, which were collected from different hospitals in Kuwait. The data from these studies were scattered and not linked or analysed together to highlight the big picture of the problem of ESBLs in Kuwait. This review article highlights that the amount of research on ESBLs in Kuwait is not up to the expectations of a country like Kuwait, which has high-standard research facilities. Bearing in mind that the geographic area of Kuwait is relatively small, the authors of this paper think that there might be more β-lactam bacteria spreading in Kuwait, which need to be explored, and that more research and more collaboration are needed among researchers in Kuwait to address this risky situation.

Unregulated underground group mining in China has led to problems such as unclear locations and complex shapes of mine goafs in mineral engineering, posing serious safety hazards for subsequent mining operations. This paper takes mineral engineering with complex mine goafs as the research object, integrates multi-survey data from surface deformation remote sensing monitoring and 3D laser scanning measurement to survey the area where the surface deformation rate reaches 14cm/ year, accurately identifies the location of risky mine goafs, and constructs detailed representations of the real shapes of the complex mine goafs inside the mineral engineering. The FLAC^3D 6.0 software is used to establish a 3D numerical simulation model of the mine goafs, fully considering the mining process, and conducting characteristic analysis of the stress distribution, failure range and surface deformation response of the mine goafs, revealing the impact of void deformation on the stability of the mine. The numerical simulation results are combined with on-site investigations to verify whether geological disasters have been caused by mine goafs. The research methods and results can provide effective technical means for the detailed survey and stability assessment of mineral engineering with complex mine goafs, which can help to reduce the risk of geological disasters in mines and improve the safety of mineral engineering.

Poland is a country rich in mineral resources with a diversified resource base. Energy resources play a key role, as they are strategic resources ensuring the country’s energy security. Strategic resources, the recovery of which is highly risky and the possibilities of substitution are small, are critical resources for the Polish economy. These are the resources included in the list of critical resources for the European Union. The conducted review of mineral resources in Poland showed a large difference between the levels of actual resources and the resources of deposits. Therefore, supporting the mineral resources market is one of the key strategic areas of the Polish economy. This study aims to identify barriers that have a significant impact on the activities of entities in the raw materials sector. The tool used was the PESTEL analysis of companies operating in the raw materials sector. The aim of this study based on the assessment of experts familiar with the raw materials market and dealing with its challenges was to determine the main factors driving the raw materials market. These include the EU’s decarbonization policy, a complex system and relatively high level of taxes, a lack of qualified specialists, a market delay in terms of technological development, an environmental policy focused on a circular economy and renewables, and the problem of raw material depletion. The earlier identification of the market gap in the mineral resources industry in Poland in terms of business development opportunities indicated that IT and ICT would be possible directions of development. Therefore, an analysis of the industry was carried out in terms of business development opportunities. An assessment of the impact of individual factors on the activities of IT entities in the raw materials sector in Poland was carried out. The factors that most determine running a business in the diagnosed IT gap in the RM include a lack of government support for IT investments, new trends resulting from the growing importance of ICT in everyday life, the pandemic situation and the subsequent crisis of many companies on the market, the unstable financial condition of the main customer groups, and the lack of qualified personnel, equipment, and appropriate technology. The presented results may have practical implications, among others, for new economic players who want to establish their companies and conquer the raw materials market. On the one hand, they indicate opportunities, and on the other, they point to threats that may appear in their business life. Full article

This study investigates the cognitive processes underlying chess expertise by examining planning, cognitive reflection, inter-temporal choice, and risky choice in chess players. The study involves 25 chess players and 25 non-chess players, comparing their performance on the Tower of London (TOL) task, Cognitive Reflection Test (CRT), inter-temporal choice (ITC), and risky choice tasks. Results indicate that chess players outperform non-chess players in TOL and CRT, showing superior planning and cognitive reflection abilities. Chess players also prefer future rewards over immediate ones in ITC, suggesting a higher propensity for future more rewarding options. In risky choice tasks, chess players made more decisions based on expected value than non-chess players, but the evidence in favour of differences between groups is very weak. Despite this study not being able to establish causality, the findings highlight the cognitive advantages associated with chess expertise and suggest potential areas for further research on the transfer of cognitive skills from chess to other domains and differences in general abilities between experts and novices.

Background: Over the counter (OTC) medications are readily accessible to the public and can be obtained without a prescription for self-care. Ensuring their safe and effective use is essential to safeguarding the well-being of the region’s diverse population. This research explores public attitudes and behaviors toward OTC medications in the Western Region of Saudi Arabia in order to inform and advance public health initiatives. Method: This cross-sectional study was conducted in the Western Region of Saudi Arabia. A validated questionnaire was used to survey 200 respondents. The collected data were analyzed using frequencies and percentages. The demographic–OTC medication purchase relationship was examined using the chi-square test. Results: Among the 200 participants, 79.5% were aware of potential drug interactions, and 74% supported stricter regulations on OTC sales. However, only 29.5% believed OTC medications are generally safe without a doctor’s prescription. Notably, 15.5% reported exceeding recommended dosages, and 66% admitted sharing medications. Participants commonly relied on healthcare professionals for advice (64.6%). Despite moderate knowledge, many exhibited risky behaviors, highlighting gaps in consumer awareness and safety practices. Conclusions: It is critical to determine the degree of public knowledge in this field in order to identify gaps in consumer awareness of OTC medications and specific areas that may demand targeted educational programs in Saudi Arabia. Information on potential side effects and circumstances that exclude the use of over the counter medications must also be examined. Attitudes towards symptom management and a tendency for self-medication may influence the use of OTC as an alternative to seeking medical advice. Full article

This study investigates the association between aggressive driving behavior and elderly pedestrian traffic accidents using the Explainable Artificial Intelligence (XAI) method. This study focuses on Seoul, South Korea, where an aging population and urban challenges create a pressing need for pedestrian safety research. The analysis reveals that aggressive driving behaviors, particularly rapid acceleration, rapid deceleration, and speeding, are the most influential factors on the frequency of and deaths from elderly pedestrian traffic accidents. In addition, several built environments and demographic factors such as the number of crosswalks and elderly population play varying roles depending on the spatial match or mismatch between risky driving areas and accident spots. The findings of this study underscore the importance of tailored interventions including well-lit crosswalks, traffic calming measures, and driver education, to reduce the vulnerabilities of elderly pedestrians. The integration of XAI methods provides transparency and interpretability, enabling policymakers to make data-driven decisions. Expanding this approach to other urban contexts with diverse characteristics could validate and refine the findings, contributing to a comprehensive strategy for improving pedestrian safety globally.

Agriculture, livestock, and forestry are crucial in mitigating hydrogeological risks, such as floods, particularly severe in the Mediterranean region. Still, the ecosystem services (ESs) provided by these activities are often undervalued. However, to assign them an economic value and ensure their effective incorporation into decision-making processes and territorial planning, they must first be recognized, appreciated, and deemed necessary by society. Despite several studies on ESs in the primary sector, research on agroecosystem flood regulation is limited, leaving key aspects unaddressed for decision-makers. No previous studies explicitly address the evaluation of ESs provided by agriculture, livestock, and forestry businesses in hydrogeological risky environments, especially in flood-prone areas. This study investigates the perception of the ESs provided by the above activities, focusing on those furnished in areas subject to hydrogeological instability. It also focuses on Sardinia (Italy), which is highly susceptible to hydrogeological instability. Through a quantitative survey of 270 residents and non-residents, the research provides evidence of society’s perception of the above ESs. Supporting ESs obtain greater appreciation in crop activities, particularly concerning the preservation of pollinating insects, soil fertility, biodiversity, and water quality. Among the regulatory Ess, appreciation is most prominent in fire risk management and flood risk regulation. Similar arguments can be made for livestock activities. Forestry activities are perceived as key players in managing flood risk, landslide risk, soil erosion, and climate change. The Multiple Correspondence Analysis indicates that appreciating one ES often leads to the recognition of others. Additionally, a set of Logit Regressions showed that while age and gender do not influence ESs perception, education level and awareness of climate change-related emergencies play a significant role. Those findings support more informed decision-making and fostering sustainable practices in areas at risk of hydrogeological disasters and lead to several important implications for practitioners, academics, and policymakers.

Fibrous dysplasia is an uncommon bone disorder affecting various parts of the skeleton, often affecting facial and cranial bones. In this case, a 10-year-old patient was diagnosed with fibrous dysplasia of the ethmoid sinus at an early age. The patient has experienced nasal congestion, snores, and worsening nasal patency since 2019. A CT scan revealed an expansive proliferative lesion, likely from the frontal or ethmoid bone, protruding into the nasal cavity, ethmoid sinus, and right orbit. The tumor causes bone defects in the area of the nasal bone, leading to fluid retention in the peripheral parts of the right maxillary sinus. The patient’s parents decided not to undergo surgery to remove the diseased tissue and reconstruct the area, as it would be very extensive, risky, and disfiguring. The patient is being treated conservatively with an MRI, with a contrast performed approximately every six months and infusions of bisphosphonates. Despite the lesion’s size, the patient does not experience pain characteristic of dysplasia, and functions typically. Fibrous dysplasia of bone is a rare condition that presents with the most visually apparent manifestations, often mistaken for other bone conditions. Advanced diagnostic tools, like CT and MRI, are used to identify conditions affecting the ethmoid sinus more frequently. However, diagnostic errors often occur in imaging studies, leading to confusion. The most common period for clinical manifestations and diagnosis is around 10 years of age. The preferred approach in managing fibrous dysplasia involves symptomatic treatment, which can alleviate airway obstruction, restore normal globe position and visual function, and address physical deformities. Surgical intervention is recommended only for patients with severe functional impairment, progressive deformities, or malignant transformation. Full article
