Forest fires endanger ecosystems and human life, making early detection crucial for effective prevention. Traditional detection methods are often inadequate due to large coverage areas and inherent limitations. However, drone technology combined with deep learning holds promise. This study investigates using small drones equipped with lightweight deep learning models to detect forest fires early. A high-quality dataset constructed through aerial image analysis supports robust model training. The proposed YOLO-UFS network, based on YOLOv5s, integrates enhancements such as the C3-MNV4 module, BiFPN, AF-IoU loss function, and NAM attention mechanism. These modifications achieve a 91.3% mAP on the self-built early forest fire dataset. Compared to the original model, YOLO-UFS improves accuracy by 3.8%, recall by 4.1%, and average accuracy by 3.2%, while reducing computational parameters by 74.7% and 78.3%. It outperforms other mainstream YOLO algorithms on drone platforms, balancing accuracy and real-time performance. In generalization experiments using public datasets, the model’s mAP0.5 increased from 85.2% to 86.3%, and mAP0.5:0.95 from 56.7% to 57.9%, with an overall mAP gain of 3.3%. The optimized model runs efficiently on the Jetson Nano platform with 258 GB of RAM, 7.4 MB of storage memory, and an average frame rate of 30 FPS. In this study, airborne visible light images are used to provide a low-cost and high-precision solution for the early detection of forest fires, so that low-computing UAVs can achieve the requirements of early detection, early mobilization, and early extinguishment. Future work will focus on multi-sensor data fusion and human–robot collaboration to further improve the accuracy and reliability of detection. Full article

With the acceleration of urbanization, the accessibility and equity of urban green spaces have become crucial issues in urban planning and public health. In the context of the 15-min living circle, whether residents can conveniently reach parks within a walkable or bikeable time frame directly impacts their quality of life and social well-being. Traditional park accessibility evaluation methods, such as the G2SFCA, effectively measure accessibility but fail to fully account for the diversity of travel modes and the impact of regional disparities on equity. This study employs the TB-G2SFCA method, integrating the concept of the 15-min living circle, to analyze the equity of park accessibility in the Dianchi Lake ring area of Kunming under different travel modes. The findings reveal significant disparities in park accessibility for walking and cycling, particularly in suburban communities distant from the city center, where many areas cannot reach a park within 15 min. Although accessibility improves under driving and public transit modes, resources remain concentrated in well-connected areas, leaving peripheral regions with insufficient access. Compared to the traditional G2SFCA method, the TB-G2SFCA approach more accurately reflects spatial differences and equity issues across travel modes. This study suggests that future urban park planning should optimize resource allocation, improve transportation networks, and enhance park accessibility in peripheral areas—especially for walking and cycling—to achieve a more equitable and sustainable distribution of urban green spaces.

Focused ultrasound (FUS) is an emerging noninvasive technology with significant therapeutic potential across various clinical domains. FUS enables precise targeting of tissues using mechanisms like thermoablation, mechanical disruption, and neuromodulation, minimizing damage to surrounding areas. In movement disorders such as essential tremor and Parkinson’s disease, MR-guided FUS thalamotomy has demonstrated substantial tremor reduction and improved quality of life. Psychiatric applications include anterior capsulotomy for treatment-resistant obsessive-compulsive disorder and major depressive disorder, with promising symptom relief and minimal cognitive side effects. FUS also facilitates blood-brain barrier opening for drug delivery in neurological conditions like Alzheimer’s disease. Musculoskeletal applications highlight its efficacy in managing chronic pain from knee osteoarthritis and lumbar facet joint syndrome through precise thermal ablation. Additionally, FUS has shown potential in neuropathic pain management and peripheral nerve stimulation, offering innovative approaches for amputees and cancer survivors. Cognitive and neuromodulatory research underscores its ability to enhance motor function and interhemispheric cortical balance, benefiting stroke and traumatic brain injury rehabilitation. Despite these conditions frequently leading to various kinds of disabilities, no direct exploration of the possible FUS application in rehabilitation is yet available in the literature. All this considered, this review aims to discuss how FUS could be applied in rehabilitation, exploring the current status of knowledge and highlighting future directions. Full article

Railways are considered an environmentally sustainable mode of transportation but can pose significant environmental challenges due to their operation and associated activities. Among these, noise generation is a persistent source of public complaints. In Korea, a maximum distance of 100 m from buildings has been proposed for new railway developments in residential areas, although this guideline lacks a solid foundation based on experimental evidence. Noise barriers are often installed as a mitigation measure; however, there is no standardized guideline for their height in relation to their effectiveness at varying distances. The distances and altitudes set in this study took into account accessibility and the height of noise barriers on actual railway sites. In particular, we examined the effects of altitude above and distance from a railway site under the assumption that the prefrontal cortex would be physiologically affected by noise exposure. In this study, we conducted the first analysis in Korea of cerebral blood flow changes in response to noise, to assess quantitatively the stress effects caused by railway environmental noise at varying distances from, and altitudes above, a railway. Using functional near-infrared spectroscopy (fNIRS), we measured prefrontal cortex activation in 10 adult males (average age: 33.2 years). Brain activation was evaluated under different distances from (40 and 100 m) and altitudes above (1st and 4th floors of a building) a railway through a paired-sample t-test analysis. Discomfort was felt at relatively close distances to the railway, and there were no differences in perceived discomfort between the examined floors. Brain activation due to environmental noise was highest in channel 43 (left DLPFC) for altitude (floor) and in channel 37 (left FPC) for distance. Significant differences in activation were observed in the corresponding Brodmann areas, varying based on altitude and distance (p < 0.05). These results provide valuable scientific data for the preliminary design phase of new railway developments, particularly with regard to determining appropriate residential distance and noise barrier specifications, to enhance comfort of nearby residents. Furthermore, they may contribute to the improvement of quality of life by reducing stress caused by railway environmental noise. Full article

Background/Objectives: Art-based interventions have been shown to enhance communication skills in children with autism spectrum disorder (ASD), yet their impact on prefrontal hemodynamics remains unclear. Methods: This study employed functional near-infrared spectroscopy (fNIRS) to examine hemoglobin oxygenation (HbO) changes in the prefrontal cortex of school-age children with ASD, providing empirical support for its therapeutic efficacy. Sixty age-matched children participated in a 9-week art therapy program, including twenty ASD children and forty typically developing peers. Assessments included self-portrait drawing (SPD), the Diagnostic Drawing Series (DDS), and the General Quality of Life Inventory (GQOL-74). In addition, we performed fNIRS measurements in the ASD participants and observed changes in prefrontal HbO at rest and while drawing. Results: The drawing intervention significantly enhanced drawing ability, emotional expression, and cognitive skills, with the intervention group outperforming the controls. ASD participants exhibited distinct prefrontal connectivity patterns with visual, motor, and language-related regions, including the dorsolateral prefrontal cortex, frontal eye field, and Broca’s area. Task-based painting interventions indirectly influenced the frontal lobe’s hemodynamic characteristics, indicating drawing intervention as an effective intervention for ASD. Full article

Epileptic seizures, a leading cause of global morbidity and mortality, pose significant challenges in timely diagnosis and management. Epilepsy, a chronic neurological disorder characterized by recurrent and unpredictable seizures, affects over 70 million people worldwide, according to the World Health Organization (WHO). Despite significant advances in medical science, accurate and timely diagnosis of epileptic seizures remains a challenge, with misdiagnosis rates reported to be as high as 30%. The consequences of misdiagnosis or delayed diagnosis can be severe, leading to increased morbidity, mortality, and reduced quality of life for patients. Therefore, this paper presents a novel approach to enhancing epileptic seizure detection through the integration of Synthetic Minority Over-Sampling Technique (SMOTE) for data balancing and a Hybrid Feature Selection Technique—Principal Component Analysis (PCA) and Discrete Wavelet Transform (DWT). The proposed model aims to improve the accuracy and reliability of seizure detection systems by addressing data imbalance and extracting discriminative features from electroencephalograms (EEG) signals. Experimental results demonstrate substantial performance gains, with the Support Vector Machine (SVM) classifier achieving 97.30% accuracy, 99.62% Area Under the Curve (AUC), and 93.08% F1 score, which outperform the results of the existing studies from the literature. The results highlight the effectiveness of the proposed model in advancing seizure detection systems, highlighting the potential to improve diagnostic capabilities and patient outcomes. Full article

Social interaction is crucial for social sustainability and quality of life. This research focuses on recreational parks in residential neighborhoods in the Dammam Metropolitan Area (DMA) to enhance social interaction. The study is designed to identify and prioritize factors affecting social interaction in the recreational parks in the residential neighborhoods in the Dammam Metropolitan Area (DMA). All factors are extracted from literature studies relevant to social interaction among individuals in recreational parks. This study follows the methodology of an expert-based questionnaire to weigh each factor according to a scale from “strongly agree” to “strongly disagree” regarding the extracted factors that may influence social interaction in recreational parks. The findings emphasized the importance of the demographic characteristics of neighborhood residents, the physical characteristics of recreational parks, and social sustainability characteristics in influencing social interaction among neighborhood residents in the recreational parks in the DMA. The analysis of the demographic characteristics showed that the age group of the neighborhood residents is the most effective factor on social interaction in the recreational parks in DMA, with a score of 4.53. Secondly, the analysis of the physical characteristics of the recreational parks showed that the periodic maintenance of the recreational park is the most effective factor on social interaction in DMA, with a score of 4.79. Thirdly, the analysis of social sustainability characteristics showed that safety and security is the most effective factor on social interaction in the recreational parks in DMA, with a score of 4.74. Finally, this study concluded with some recommendations to address the probable factors that may influence social interaction in the recreational parks in the Saudi context, particularly in DMA.

Background/Objectives: Primary chest wall tumors or malignancies of adjacent organs with chest wall infiltration present a significant challenge for surgical resection and reconstruction. Larger defects involving the sternum, resections in the area of the thoracic apertures, or those near the spine are difficult to reconstruct. The reconstruction has to ensure stability, to prevent paradoxical movements and lung herniation, while also achieving a satisfactory cosmetic result. The “spider web” technique restores chest wall stability by creating a web-like framework made of non-resorbable threads fixed to adjacent bony structures. Additionally, a synthetic mesh is placed over the web construct, and both layers are covered with muscles (local muscles or different types of flaps). In this prospective study, clinical data from patients who underwent surgery using the “spider web” technique were analyzed with respect to chest wall stability, procedure-specific complications, pulmonary function, and patient satisfaction. Methods: A total of 16 patients receiving 18 chest wall resections and reconstructions using the “spider web” technique were followed for at least one year. Chest wall stability and lung function (FEV1 and DLCO) were assessed. Quality of life, cosmetic satisfaction, potential functional impairment, and analgesic consumption were measured using a modified EORTC QLQ-C30 questionnaire. Results: The follow-up period ranged from 12 to 32 months. In all cases, optimal chest wall stability was maintained without impairment of respiratory mechanics. Procedure-specific complications occurred in five cases (27.8%), including seroma (one case), hematoma (two cases), necrosis at the TRAM flap donor site (one case), and mesh infection (one case), all of which were resolved without further complications. Postoperative FEV1 and DLCO were not significantly reduced compared with preoperative values. The global health status score for quality of life was 60 ± 27 points. Nine patients reported being able to ascend at least one floor of stairs without shortness of breath and half of the patients were able to participate in sports activities. One patient required prolonged analgesic medication due to chronic pain. In all cases, patients were satisfied with the cosmetic result. Both 30-day and 90-day mortality were 0%. No local recurrence at the chest wall reconstruction site occurred. Conclusions: The “spider web” technique is a highly suitable method for chest wall reconstruction, allowing covering all types of chest wall defects, regardless of size and location. This cost-effective technique not only provides optimal stability but also good functional results. Full article

Background: Kidney transplantation (KTx) significantly improves survival and quality of life in patients with end-stage renal disease. However, post-transplant well-being is influenced by multiple factors, including healthcare accessibility, satisfaction with medical care, and psychological health. This study aimed to assess the well-being of post-KTx patients in Kazakhstan and examine its associations with healthcare access, satisfaction, and anxiety. Methods: A cross-sectional study was conducted among 223 post-KTx patients in Kazakhstan. Participants were recruited through online surveys and telephone interviews. Only patients who had undergone transplantation within Kazakhstan were included. The WHO-5 Well-Being Index was used to measure well-being, and additional surveys assessed healthcare access, satisfaction with post-KTx care, and treatment-related anxiety. Multiple linear regression was performed to identify predictors of well-being. Results: The mean WHO-5 well-being score was 66.1 (SD = 24.6), indicating moderate well-being. Satisfaction with post-transplant information (β = 0.287, p = 0.015) and educational level (β = 0.172, p = 0.019) were significant positive predictors of well-being. In contrast, post-KTx anxiety (β = −0.154, p = 0.024) and difficulties in accessing medical care (β = −0.216, p = 0.014) negatively affected well-being. Patients residing in rural areas reported greater barriers to post-transplant care compared to those in urban settings (χ² = 31.6, p = 0.002). Conclusions: Post-KTx well-being in Kazakhstan is influenced by educational level, access to healthcare, satisfaction with medical information, and anxiety levels. Targeted interventions to improve access to post-transplant care, enhance patient education, and address psychological distress may help improve outcomes for post-KTx patients. Full article

Background: Sarcopenia, or loss of skeletal muscle mass, has been associated with poor outcomes (e.g., functional decline, increased mortality, and low quality of life), but its role in CTEPH remains unclear. The psoas muscle index (PMI) is a validated measure of sarcopenia. We investigated the incidence of sarcopenia using PMI in CTEPH. Methods: Retrospective analysis of a single-center cohort of patients with CTEPH with an available computed tomography of the abdomen and pelvis (CTAP). PMI was measured at the L3 level of the CTAP and was then calculated using the formula (left psoas area + right psoas area/height²). Patients in the first quartile of PMI were classified as sarcopenic. Results: We reviewed 558 patients with CTEPH, and 97 patients had an available CTAP before intervention. Sarcopenia was identified in 26 (24.8%) of the patients and was associated with worse baseline functional status (p = 0.008), higher mean pulmonary artery pressure (48 vs. 39 mmHg; p = 0.002), and higher pulmonary vascular resistance (9.9 vs. 6.8 WU; p = 0.013). Post-PTE, patients with sarcopenia exhibited longer intensive care unit (ICU) (9 vs. 4 days, p < 0.001) and overall hospital stays (24 vs. 11 days, p < 0.001), despite similar post-operative hemodynamics achieved compared to non-sarcopenic patients. Conclusions: CTEPH patients with sarcopenia have worse baseline functional class and hemodynamics. For those with sarcopenia requiring surgery, there is longer ICU and total hospitalization stays, but they achieve significant functional improvements and hemodynamics comparable to that of non-sarcopenic patients. Hence, the risk of longer perioperative hospitalization days is justified by the longer-term benefit of hemodynamic improvement. The use of PMI as part of routine pre-operative assessments could improve clinical decision-making in CTEPH patients undergoing surgical or medical intervention. Full article

Nurses are highly exposed to work-related musculoskeletal disorders (WMSDs). Several studies on this have been carried out in different Asian countries, but no synthesis was conducted. The aim of this study was to map the evidence of WMSDs among nurses in Asia. A systematic review and a meta-analysis with subgroups were performed during October 2024. Five open databases were scanned without a date limit. The article selection and data extraction processes were performed independently by two reviewers. The results report was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Among the 15,751 unique identified records, 40 studies were included, covering a total of 19,903 Asian nurses. A high heterogeneity (Cochran’s Q test and I² statistic) was evidenced between the studies. The meta-analysis polled an overall prevalence of 84.3% (95% CI: 81.1–87.4%). The lower back (58.4%, 95% CI: 52.9–63.8%), neck (45.7%, 95% CI: 38.1–53.2%) and shoulder (43.0%, 95% CI: 36.2–49.9%) were the three most exposed areas. Subgroup analyses have shown that the presence of WMSD is steadily increasing, and that years of practice reduce the exposure of the neck and shoulder, while the lower back becomes more exposed. Further efforts are needed to prevent WMSDs among Asian nurses, in order to improve their quality of life at work. Full article

Obstructive sleep apnea (OSA) is increasingly recognized as a chronic condition that is closely interrelated to olfactory disorders, with a significant contribution to quality of health and overall quality of life. This narrative review aims to provide a thorough overview of the emerging evidence that now integrates these two previously considered distinct physiologic systems. Studies published recently have reported a significantly higher frequency of olfactory dysfunction among OSA patients compared to the general population, which raises the possibility of a causal relationship. We explore the postulated mechanisms behind this association, namely, the chronic intermittent hypoxia, local inflammatory effect, and neuroanatomical changes attributed to OSA. The review further explores the clinical impacts of this relationship through proposing the potential for an olfactory assessment to be used as a diagnostic modality for OSA and the effects of OSA treatment on olfactory function. Thus, we explore the difficulties in treating patients who experience both and suggest future areas for research. This review attempts to bridge the gap between the existing literature and impending investigation necessary for a better management of the interaction of sleep apnea and the human sense of smell.

Interest in the balance between work and life and improving the quality of life is expected to steadily increase the number of users of forest welfare facilities. In this study, the “2023 Forest Recreation and Welfare Activity Survey” was used to analyze how characteristics of forest visits, such as visit frequency, the number of visited areas, expenditures, and the presence of companion animals, affect life satisfaction based on three visit types: daily (less than 4 h), day (more than 4 h), and overnight (more than 1 night). A hierarchical regression of 9437 respondents revealed that age, occupation, education, spouse, children, household income, and type of residence, excluding sex, were significantly correlated with life satisfaction. A hierarchical regression analysis revealed that for daily visitors, both visit frequency and companion animals increased life satisfaction. For day visitors, visit frequency, the number of visited areas, expenditures, and companion animals enhanced life satisfaction. For overnight visitors, visit frequency and expenditures positively impacted life satisfaction. Across all visit types, the frequency of forest visits consistently increased life satisfaction. This study statistically clarified how the characteristics of each visit type affect life satisfaction. The findings provide foundational data for future policies and research on forest recreation and welfare. Full article

There is abundant evidence that, following community transition or deinstitutionalization, persons with intellectual and developmental disabilities experience improvements in quality of life and well-being. However, very little research in this area has been conducted in the Canadian context. In this qualitative study, individual in-depth interviewing was used to explore the perspectives of eight Canadian mothers of adults with intellectual and developmental disabilities regarding their children’s residences and access to services after community transition. Within an interpretive description framework, narrative data collected during semi-structured interviews with participating mothers were analyzed using thematic analysis. Three main themes portraying a combination of positive and negative maternal perspectives emerged from the data: (1) quality of care, (2) quality of life, and (3) health status and behavior. The study findings bring attention to the importance of offering individualized community living options that are person- and family-centered to all persons with intellectual and developmental disabilities.

Background/Objectives: The Tc-99m dimercaptosuccinic acid (DMSA) renal scan clearly images the renal cortex, highlighting functional tissue areas and indicating regions of renal scarring, infection, malformations, or other types of renal damage. To enhance the management of paediatric cases involving renal malformations and to reduce the incidence of chronic and progressive kidney diseases in “future adults”, our study aims to identify and categorise various renal anomalies. Methods: This has been achieved by analysing the Tc-99m DMSA renal scans of a large cohort of 931 children diagnosed with different renal pathologies. After interpreting the scans, we categorised the renal malformations and cortical modifications into four groups: kidney number anomalies, positional anomalies, structural anomalies, and shape anomalies. Results: There has been a notable increase in the demand for renal scintigraphy in recent years, rising from 82 cases in 2019 to 183 cases in 2024. Structural anomalies were the most common type of malformations (73% from all patients), featuring a significant variety of cortical modifications. In total, 98 cases (93% from kidney number anomalies and 10.5% from all children) were diagnosed with renal agenesis. Additionally, 30 children (3.2% from all patients) had positional anomalies, primarily ectopic kidneys, and 54 patients (5.8% from all cases) had shape malformations, especially fused kidneys. Conclusions: Combining the Tc-99m DMSA renal scan with ultrasound provides a more reliable diagnosis of paediatric renal progressive diseases. A more accurate diagnosis allows for quicker treatment and prevention of potential complications, ultimately improving the quality of life and decreasing hospital costs of paediatric patients becoming adults.
