Abstract:Abstract: Sexual and reproductive health (SRH) is a crucial component of adolescent well-being. This study aimed to assess the level of knowledge, attitudes, and competence of health vocational high school students regarding SRH, and to identify areas requiring targeted educational interventions. A cross-sectional survey was conducted at Davultepe Vocational and Technical Anatolian High School during the fall semester of the 2020–2021 academic year. Data were collected from 157 students using the “Knowledge, Attitudes, and Behaviors of Students towards Sexual and Reproductive Health” questionnaire, which included 21 items on knowledge, attitudes, and behaviors. Descriptive statistical analysis was performed to evaluate the responses. The descriptive analysis revealed that mean Likert-scale scores ranged from 2.7 to 3.7, reflecting overall moderate-to-high levels of knowledge and agreement regarding SRH. Items such as 5, 12, and 17 showed higher means (M ≈ 3.7), indicating more positive attitudes, whereas items 4 and 6 demonstrated lower averages (M ≈ 2.7–2.8), suggesting persisting uncertainty. Most responses clustered around “Neutral” to “Agree,” confirming recognition of SRH importance but highlighting gaps in specific domains. Furthermore, 61% of participants reported that SRH was not openly discussed within their families, while 71.9% perceived sexual content in the media as negative or misleading. Despite this, 85% stated they had not experienced SRH-related health problems. Students largely acknowledged the significance of SRH education and emphasized the need for its earlier and professional integration into the school curriculum. Participants also expressed concern about sexually explicit content in the media, describing it as inaccurate and potentially misleading. These findings underline the necessity of structured, school-based SRH education beginning from secondary education onwards to address knowledge gaps and equip students with accurate, reliable information.
Abstract:African health systems increasingly consider traditional medicine integration for expanded coverage. We evaluated formal integration programs in Ghanaian district hospitals examining referral patterns and patient outcomes. Collaborative frameworks improved management of chronic conditions where traditional practitioners maintained established relationships. Quality assurance challenges persisted despite regulatory frameworks. Patient satisfaction increased with formalized integration reducing healthcare seeking delays. Our analysis informs traditional medicine policy development balancing efficacy evidence with cultural acceptability.
Abstract:Earthquake early warning systems require rapid accurate classification of seismic signals. We developed deep learning models for P-wave detection and magnitude estimation using Japanese seismic network data. Neural networks reduced false alarm rates by 40% compared to conventional threshold methods. Processing latency achieved sub-second classification enabling maximum warning times for distant earthquakes. Integration with smartphone applications extended alert reach to mobile populations. Our system enhances early warning capabilities for earthquake-prone regions.
Abstract:Post-industrial cities seek sustainable redevelopment while preserving industrial heritage identity. We analyzed adaptive reuse projects in Polish coal mining regions examining economic viability and community engagement. Successful conversions balanced heritage preservation with contemporary functional requirements. Mixed-use developments incorporating cultural facilities generated higher community support than purely commercial projects. EU structural funds enabled ambitious transformations otherwise financially unviable. Our guidelines support heritage-led urban regeneration planning in declining industrial regions.
Abstract:Platform-based gig work challenges traditional labor protection frameworks across developing economies. We interviewed 180 ride-hailing and delivery workers in Vietnam and Thailand examining working conditions and organizing strategies. Workers faced algorithmic management reducing autonomy while bearing operational costs and accident risks. Informal worker associations emerged despite platform resistance and legal ambiguities. Cross-platform solidarity actions achieved limited gains in payment transparency. Our analysis informs labor policy responses to platform economy expansion in developing regions.
Abstract:Abandoned mining sites contaminate surrounding soils with heavy metals threatening ecosystems and communities. We evaluated biochar amendments for metal immobilization at Chilean copper mining sites. Biochar reduced plant-available lead and cadmium concentrations by 65% while improving soil structure. Feedstock selection influenced metal binding capacity with woody biomass outperforming agricultural residues. Native plant establishment success increased on biochar-amended plots. Our methodology provides cost-effective remediation options for mining-impacted landscapes.
Abstract:COVID-19 pandemic exposed educational inequalities between urban and rural areas. We surveyed online learning experiences across 45 rural Nepali schools examining infrastructure and pedagogical barriers. Only 23% of students had reliable internet access while smartphone sharing among siblings was common. Teachers received minimal training for online instruction delivery. Offline content packages and radio-based lessons showed promise for connectivity-challenged areas. Our findings inform education policy for bridging digital divides in developing country contexts.
Abstract:Community ownership models shape renewable energy acceptance and benefit distribution. We analyzed Danish wind energy cooperatives examining governance structures and local economic impacts. Cooperative-owned turbines generated higher community support than corporate projects despite similar visual impacts. Revenue sharing mechanisms funded local development initiatives. Youth engagement declined as cooperatives professionalized management structures. Our findings inform community energy policy development balancing efficiency with participatory governance.
Abstract:Mangrove ecosystems provide critical services often undervalued in development decisions. We developed multi-criteria assessment frameworks incorporating carbon sequestration, fisheries support, and coastal protection values for Indonesian mangrove forests. Economic valuation revealed services worth 15,000 USD per hectare annually. Local community livelihood contributions exceeded carbon credit potential at current market prices. Spatial mapping identified priority conservation areas based on service provision intensity. Our framework supports integrated coastal zone management incorporating ecosystem service values.
Abstract:This study focuses on the hyper-arid, irrigated area of Wadi ad-Dawasir in Saudi Arabia, where soil salinisation poses a significant threat. Using a combination of Sentinel-2 series data from 2016 to 2025 and 83 electrical conductivity (EC) measurements, it is possible to analyse the joint dynamics of vegetation (NDVI) and salinity (SI, NDSI). This methodology, driven by remote sensing and field data, transforms measurements and estimated salinity values into a continuous, spatialised history of soil-vegetation-climate interactions. The aim is to mitigate stress and maximise the resilience of agricultural land and plant vigour by identifying areas at risk, degradation trends, and key periods for targeted intervention. However, the results of salinity mapping modelling, supported by a statistical analysis of the relationships between NDVI and EC, reveal no robust statistical correlation between optical indices and direct measurements.\nThis insignificant correlation indicates that, in this specific context, the spectral response of vegetation is influenced by a variety of interacting intrinsic and extrinsic factors that mask or reduce the distinct signal of salt stress. Consequently, NDVI is an inadequate quantitative proxy for soil salinity in this case study, where values remain generally stable and electrical conductivity (EC) values are mostly low (below 2 dS/m), indicating satisfactory soil integrity. In the context of operational monitoring, however, NDVI appears to be a more relevant early warning indicator than optical salinity indices.
