Enhancing Multilayer Glass Transmittance through Particle Swarm Optimization: An Experimental Approach

Abstract. This study focuses on enhancing the solar transmittance of multilayer glass in buildings located in cold northern regions to improve natural lighting efficiency and maintain indoor warmth in harsh climates. The Particle Swarm Optimization (PSO) algorithm is utilized to optimize the glass layer thickness, and an optical model is constructed to calculate the light transmittance of the multilayer glass. Through simulations and experimental analysis, the impact of different glass thickness combinations on overall transmittance is investigated. The study examines the optical properties of gradient glass and calculates changes in light transmittance under varying thickness combinations using MATLAB software. The PSO algorithm is applied for global optimization to identify the glass thickness combination that maximizes light transmittance within the specific visible light range (400nm-800nm). The experimental results, including spectral energy distribution before and after sunlight transmission, validate the accuracy of the theoretical model. The findings demonstrate that the optimized glass thickness combination significantly improves solar transmittance, especially within the visible light band, contributing to more energy-efficient and comfortable building environments in cold regions. Additionally, the potential of the PSO algorithm in global search and local convergence is analyzed, suggesting future research directions to further enhance optimization through dynamic adjustments or combining with other algorithms.

Evaluation of Effectiveness and Multi-Scenario Analysis of Land Use Development Strategies and Ecological Protection Redlines on Carbon Storage in the Great Bay Area of China Using the PLUS-InVEST-PSM Model

Land use change is a key factor affecting the carbon storage of terrestrial ecosystems. Most studies focus on formulating different land development strategies to mitigate the adverse impacts of land development, while fewer discuss the effectiveness of these strategies. In the context of varying socio-economic development and limited budgets for ecological conservation, evaluating effectiveness is essential for selecting the most suitable land development strategy. This research proposed a Patch-Generating Land Use Simulation-Integrated Valuation of Ecosystem Services and Tradeoffs–Propensity Score Matching (PLUS-InVEST-PSM) model to evaluate the effectiveness of different land use development strategies in the Greater Bay Area of China as a case study. Specifically, this study analyzed the historical land use changes from 2000 to 2020 and mapped the multi-scenario patterns of land use and carbon storage with the PLUS and the InVEST models from 2030 to 2050. Then, this study employed the PSM model, along with a series of criteria (i.e., similar ecological backgrounds and parallel historical trends), to evaluate the effectiveness of the ecological development strategy and ecological protection redlines on carbon storage compared with the natural development strategy. The results indicate that the ecological development strategy and the ecological protection redline can prevent the decline in carbon storage. However, in the ecological development strategy, implementing the ecological redline policy may hinder the growth of carbon storage within the ecological redline area. Compared with the PLUS-InVEST-PSM model, the comparison between the subregions could underestimate the efficiencies of evaluation, partly due to underestimating the negative impact of urban development on carbon storage. These findings will help governments develop comprehensive and systematic land use policies to achieve carbon peaking and carbon neutrality goals. Also, the approach would help to further explore the broader impacts of land use development strategies on the overall regional ecological environment, such as biodiversity and ecosystem services.

An investigation into the shifting landscape preferences of rural residents in Taiwan and their relationship with ecological indicators.

Rapid urbanization has significantly altered landscape environments in both urban and rural regions, and these landscapes have been demonstrated to play a pivotal role in human well-being. This study develops a coherent framework that integrates landscape change, landscape ecological indicators, and landscape preferences within the context of the evolving landscape environments of rural communities in Taiwan. Four distinct types of rural communities were selected, and a quantitative methodology was employed to investigate the variations and transformations in landscape preferences among rural residents in the context of landscape change. A qualitative methodology was employed to investigate the relationship between landscape ecological indicators and landscape preferences. The study's findings indicate significant temporal variations in residents' landscape preferences, with landscape beauty, stewardship, and coherence emerging as key determinants in the evaluation of these preferences. Landscape ecological indicators were found to be significantly correlated with variables such as landscape complexity, landscape beauty, openness, naturalness, and comprehensive landscape assessment. The findings of this study indicate that design planners, land managers, and public sector organizations can employ multidimensional thinking in the management of rural landscapes to align with the visual aesthetic preferences of rural residents.

Exploring the Impact of Regional Environment and Institutional Factors on Operation Period of Nursing Facilities in Taiwan.

This study examines factors influencing the operational durations of nursing facilities in Taiwan. It departs from previous closure-focused research by analyzing the duration of facility operation. A Cox regression model was employed to assess the impact of regional, governmental, and individual institutional factors on 199 facilities across diverse areas in Taiwan from 2011 to 2019. Results demonstrate closure hazards associated with rising property prices, particularly for rented facilities, with metropolitan locations exhibiting superior survival rates and lower institutional appraisal grades significantly increasing closure. Additionally, operator background, facility type, and bed occupancy emerged as influential factors. These findings underscore the financial vulnerability of rented facilities to market fluctuations and the challenges associated with adjusting resident fees. Furthermore, the study highlights the unique challenges faced by facilities in low-density areas regarding resident access to resources. Policymakers should closely monitor regional factors and consider proactively implementing early warning systems to address these challenges.

Musical intangible cultural heritage refers to the transmission of intangible cultural expressions with cultural connotations and social significance through music as a carrier. It covers a rich variety of musical forms and traditional musical instruments, and embodies the creation and inheritance of music by human beings in different historical periods and regional environments. Through the inheritance of traditional music, it can promote and pass on national culture and local culture, and strengthen people's sense of cultural identity and belonging. Music has the ability to cross languages and cultures, and through music inheritance, it can promote cultural exchanges and communication between different regions and nationalities, and enhance mutual understanding and friendship. For individuals, music heritage can enhance their sense of identity, self-knowledge and self-confidence. The safeguarding of musical intangible cultural heritage is a brand new field and a mainstream discourse in the field of international cultural studies. At the same time, it should be the historical mission of every individual worker related to music.

Shufflenetv2UNet: An improved neural network model for grassland sample coverage extraction

AbstractAccurate extraction of grassland sample coverage is crucial for regional ecological environment monitoring. Due to the strong feature learning capability, high flexibility, and scalability of deep learning methods, they have great potential in grassland sample extraction modelling. However, we still lack a model that can achieve both lightweight structure and effective performance for small object segmentation to considering the small target characteristics of grassland vegetation and the requirements for model deployment in later stages. Here, we combined the UNet model, which performs well in small target segmentation, with the lightweight network Shufflenetv2 model, proposing an improved UNet neural network, Shufflenetv2UNet, for grassland sample coverage extraction. The core of Shufflenetv2UNet is the removal of maximum pooling and double‐layer convolution modules from downsampling in the UNet neural network. In addition, the Inverted Residual Block structure module from Shufflenetv2 was added to achieve a lightweight model and improved extraction accuracy. The Shufflenetv2UNet achieves an accuracy of 98.23%, with a parameter size of 50.74 M, and a model inference speed of 0.004 s. Compared to existing extraction methods, this model has advantages in prediction accuracy, parameter size, and model inference speed. Moreover, Shufflenetv2UNet achieved different types of grassland sample coverage extractions, with good robustness, generalization, and universality, enabling investigators to quickly and accurately obtain grassland sample coverage. This allows more dynamic and accurate ground measurement data for regional grassland environmental monitoring.

Multi-Scale Supply and Demand Relationships of Ecosystem Services Under Multiple Scenarios and Ecological Zoning to Promote Sustainable Urban Ecological Development in Arid Regions of China

Predicting and analyzing the supply and demand relationship of ecosystem services provides theoretical support for the improvement of the ecological environment. This paper takes Bortala, a typical oasis city with a fragile ecological environment in the arid northwest region, as a case study. Based on the GMOP-PLUS-InVEST coupled model, it predicts the coupling coordination and matching degree of the supply and demand connection of ecosystem services such as habitat quality (HQ), carbon storage (CS), water yield (WY), and soil erosion (SD) under four scenarios. The findings indicate that from 2020 to 2035, HQ, CS, and WY have basically achieved coupling coordination at both scales. However, there is a notable disparity in the supply and demand of water resource production and carbon emission production. To ensure the long-term balance of ecosystem service supply and demand (ESSD), the research area was ultimately divided into five ecological zones: ecological conservation zone, ecological agriculture zone, ecological moderate development zone, ecological improvement zone, and ecological protection zone. It could offer insights for guiding the sustainable growth of ecologically vulnerable zones in the future.

Suggestions in this study need to develop quality standards for services to establish independent nursing practices and increase the involvement of professional organizations in fostering nurses who want to open independent nursing practices.

Air pollution under formal institutions: The role of distrust environment

Formal trust is an important formal institution that may significantly impact the environment. This study uses regional distrust environment as a reverse proxy variable for formal trust and studies the impact of formal trust on corporate sulfur dioxide emissions. This study finds that the environment of distrust significantly increases the sulfur dioxide emission levels of enterprises, which means that formal trust affects the environmental management strategies of enterprises. This study also finds that some other formal institutional factors, which include marketization, the development of intermediate organizations, the legal system environment, and GDP levels, have moderating effects on the impact of distrust environment on corporate sulfur dioxide emissions. In addition, climatic conditions including temperature, humidity, and precedence, as well as the location of the enterprise, have certain moderation effects. Mechanism analysis indicates that distrust environment affects corporate sulfur dioxide emissions through the increase in coal sulfur content in enterprise production, the decrease in exhaust gas processing capacity, the reduction in financing capacity, and the decline in social and environmental responsibilities. Finally, this study finds through further analysis that the local government appears to have noticed this negative impact, and the regions with a distrust environment tend to increase their environmental regulation intensity.

How have regional evacuation conditions changed over time? evacuation model for alternative scenarios given the accident environment, regional environment, and social systems.

The rapid evacuation in major leak accidents during hazardous chemical transportation is critical for protecting people in risk areas. An approach integrating the accident environment, regional environment, and social system is proposed to perform evacuation evaluation in such accidents. An agent-based modeling framework consisting of warning mechanisms, evacuation preparation process, as well as evacuation modes and movement process, is developed to comprehensively model the evacuation process. The regional environmental and social system data from 1964 to 2020 of Jiangsu Province in China is applied to analyze whether the changes in evacuation conditions have correspondingly affected evacuation effectiveness. A regional evacuation model simulating a real liquid chlorine leak accident during transportation in Wuzhong of Jiangsu Province is constructed to test the effectiveness and applicability of the proposed method. It is found that a 9% change in the diffusion rate of warning messages triggered by environmental cues with the evolution of the study area settlements following the chronological changes; while the evolution of media technology allows for the rapid diffusion of warning messages and the rapid loading of a large number of individuals into the regional evacuation network; Years with faster warning diffusion have not been the most efficient ones in terms of overall evacuation; The distribution of buildings and population substantially impacts the overall evacuation effectiveness, while the former has a more significant impact. The study results can provide information for public emergency authorities to develop effective early warning resource allocation and evacuation organization plans.

Deciphering the driving factors and probabilistic health risks of potentially toxic elements in arid surface water: Insights from the Tarim River Basin

Potentially toxic elements (PTEs) in surface water in arid areas pose a serious threat to environmental safety and human health within a basin. It is important to determine the factors controlling PTEs and to assess the likelihood that they will pose a risk to human health in order to support the development of environmental protection and risk management strategies. In this study, a structural equation model and Bayesian method were combined to discuss the distribution and probabilistic health risks of PTEs in surface water in arid area, and the Tarim River Basin was taken as a case study. The results show that the average concentrations of As, Co, Cu, and Ni in the surface water in the Tarim River Basin ranged from 0.04 to 2.92 μg/L, which do not exceed the international standard values. However, the maximum value of As (19.20 μg/L) exceeded both the recommended drinking water standards and the Chinese irrigation water standards. Spatially, the high As concentrations were distributed in the upper reaches of the Kashgar River, and the high Co, Cu and Ni concentrations were distributed in reservoirs and lakes on the main stream of the Tarim River. The concentrations of the PTEs in the surface water in the basin were not only affected by random anthropogenic factors such as traffic discharge, agricultural activities and mining industry, but were also directly and indirectly influenced by climatic factors. The results of the probabilistic health risk assessment showed that the 95th percentile the total hazard index for infants exceeded the allowable value of 1, and the total carcinogenic risk of PTEs exposure in four age groups was at the notable level. In this study, we conducted a comprehensive analysis of the controlling factors and health risks associated with PTEs in surface water in the Tarim River Basin, and the findings are expected to provide a scientific basis for regional water environment management and safety control.

Health disparities among in multicultural and non-multicultural families in South Korea

Abstract South Korea has experienced significant immigrant growth, with international marriages playing a key role in this demographic change. In 2019, international marriages accounted for 10.3% of all marriages, increasing the number of multicultural households. Multicultural families in Korea faced controversies over accepting new members in a society traditionally considered racially and ethnically homogenous. In rural areas, where patriarchal and conservative values prevail, there is greater discrimination and negative perception towards foreigners compared to urban areas, impacting access to healthcare. This potentially adversely affects the health of married immigrants. However, research on this issue is limited. This study aims to examine the differences in health behaviors, access to care, and health status between multicultural and non-multicultural families in rural and urban areas. Using a cross-sectional study design based on the 2023 Community Health Survey, the sample included 228,216 adults from non-multicultural families and 3,373 adults from multicultural families. Adjusted differences in outcome were estimated using regression models, including linear probability and logistic models. Overall, there were minimal or no differences in health behaviors and health status between adults from multicultural and non-multicultural families. However, significant differences were observed in access to care, such as annual health check-ups (0.72 [0.64, 0.81]) and vaccinations (0.84 [0.76, 0.94]). Non-multicultural families showed regional differences in all outcomes, whereas multicultural families exhibited minimal or no regional differences. These findings suggest that multicultural families may face barriers beyond regional environments, limiting their access to care and potentially leading to long-term negative health outcomes. Targeted policy development for multicultural families in Korea is necessary to address this issue. Key messages • Access to health care may vary for individual and local factors, especially for people with different ethnicities or cultures. • Multicultural families may encounter greater barriers than individual and regional characteristics, requiring the development of tailored policies for immigrants and multicultural families.

11.O. Scientific session: Mental Health Among Sexual and Gender Minority Populations in Diverse Structural Stigma Environments

Abstract Research conducted across numerous countries finds that sexual minority (e.g., lesbian, gay, and bisexual [LGB]) and gender minority (e.g., transgender [T]) individuals represent high-risk populations for poor mental health and suicidality. These disparities are believed to be a consequence of a stigmatizing environment and sexual and gender minority individuals’ disproportionate exposure to stigma-based stress compared to cisgender (i.e., non-transgender) heterosexuals. Stigma occurs at multiple levels to compromise LGBT individuals’ health. At the structural level, stigma manifests as unjust laws, policies, and cultural norms that deny, or fail to protect, the equal rights of LGBT individuals. At the interpersonal level, stigma manifests as discrimination in social interactions, social exclusion, and outright victimization. At the individual level, stigma can tax LGBT individuals’ coping resources by requiring costly behavioral strategies such as concealment of one’s LGBT identity. In this workshop, four studies from different regional environment with varying degree of structural stigma will be presented, i.e., the USA, Switzerland, Rwanda, and Kenya. They resent novel findings on the processes and mechanism underlying LGBT populations increased risk of mental health and links between stigma experiences at different levels. Dr. Clark will present a study of how negative news media coverage influence suicidality among LGBT young adults in the USA using intensive longitudinal assessments. Dr. Pfister will present findings from in-depth interviews concerning suicidality with individuals representing a wide variety of sexual and gender minority identities in Switzerland. Dr. van der Star will present a study exploring how structural stigma environments are linked to interpersonal and individuals level stigma experiences in sexual minorities representing different generations of LGBT populations. Dr. Stojanovski will present data from surveys and interviews of LGBT populations in Kenya and Rwanda focusing on experiences of discrimination and mental health. Key messages • Negative media reporting, discrimination, and barriers to health care can influence mental health and suicidality among LGBT individuals. • Identity concealment may represent a mechanism through which sexual minorities navigate structurally stigmatizing climates.

Reform of Budget Performance Management and Local Financial Pressure in China

As the situation of tight fiscal balance among local governments in China continues to intensify, research on how to release local fiscal pressure has attracted much attention. At the national level, the reform of budget performance management has significantly reduced the financial pressure on local governments; Mechanism analysis shows that reform can alleviate local fiscal pressure through two channels: improving fiscal expenditure performance and optimizing regional institutional environment; The analysis of regional heterogeneity shows that the reform only reduced the local fiscal pressure in the eastern region, while the fiscal pressure in non eastern regions did not decrease but instead increased. Finally, this article proposes suggestions for addressing the issues of unbalanced and insufficient reforms, which provide policy insights for China's subsequent efforts to improve the quality and efficiency of budget performance management.

Does government transparency promote firm innovation? Evidence from China

ABSTRACT This study investigates the relationship between government transparency and firm innovation, exploring the mechanisms through which government transparency influences firm innovation using Chinese provincial-level and firm-level data from 2013 to 2020. The findings reveal a significant positive association between government transparency and both firm innovation input and output. Mechanism analysis suggests that government transparency enhances firm innovation by fostering improvements in the regional institutional environment. Furthermore, the study identifies heterogeneity in the effects, indicating that state-owned enterprises (SOEs) and high-tech firms derive greater benefits from government transparency. This research contributes to the existing literature by addressing the role of government transparency in promoting firm innovation and offers valuable insights for practical applications.

Characteristics, impacts and future research directions of Mongolian peatlands

Mongolia is an important peatland distribution area in the world. Over the past few decades, Mongolian peatlands have undergone significant degradation due to climate change and human activities, yet there remains substantial uncertainty about the impacts of Mongolian peatland changes on regional environment and human society. Here, compiling the data of peatland distribution, climate, human activity, as well as the permafrost, we systematically review the distribution, changes, and the ecosystem service values of the Mongolian peatlands in the face of climate warming and intensifying human activities. The current data show that the total area of peatland in the Mongolian is 15500~27000 km2, and most of the peatlands are distributed in permafrost regions, while the accuracies of these maps were not assessed. In addition to climate warming, overgrazing, mining activities, and transportation, we suggest permafrost degradation also poses significant threatens on the peatlands. Although the importance of Mongolian peatlands has been recognized, the ecosystem service values, including water provision, habitat quality, carbon fixation, soil conservation, and wind erosion prevention largely remain unknown. Currently, efforts have been made to protect the Mongolian grassland, but there are no specific measures to combat peatland degradation. To better understand the changes and roles of peatland ecosystems in regulating regional development, we propose three research directions for future studies: 1) produce a detailed map of peatland distribution based on field survey data, new remote sensing data, and new algorithms; 2) Unveil the mechanisms underlying the interaction of peat, vegetation, and permafrost; 3) Evaluate the ecosystem services of Mongolian peatlands. These knowledges are the scientific foundation to propose and implement measures to protect, maintain, and sustainably utilize peatlands in Mongolia.

Identification of dominant drivers of streamflow spatiotemporal variations in typical mountainous areas in the Hexi Corridor, China

Study regionTypical mountain areas in the Hexi Corridor, China. Study focusWater security and ecosystem sustainability of arid inland river basins are highly dependent on upstream streamflow. However, due to the complex geographical environment and limited observation data in the study region, the attribution of spatiotemporal variations in streamflow influenced by climate change and/or human activities remains unclear. Here, we used partial least squares regression (PLSR) and the Budyko framework to unravel the dominant drivers of spatiotemporal variation in streamflow over the past 30 yr. New hydrological insight for the regionPrecipitation, topographic wetness index, slope, forest land, gross primary productivity, hydrological connectivity, soil organic carbon content, silt content, relative relief, NDVI and gravel content dominated spatial variation in streamflow. Temporal variation of streamflow was sensitive to precipitation and land surface. Specifically, increased precipitation and land surface alteration dominated the increase in streamflow in 50 % of the watersheds and the decrease in streamflow in 33 % of them, respectively. Further, land surface alteration was dominated by expansion of agricultural and built-up areas, weakened hydrological connectivity, increased landscape aggregation and forest cover. Controlling agricultural and built-up areas and the scale of afforestation, and focusing on the dynamics of hydrological connectivity and landscape patterns in the upstream reaches are imperative to maintain the security and sustainability of water resources in the arid inland river basins.

Changes in soil quality during different ecological restoration years in the abandoned coal mine area of southern China

AbstractUnderstanding the effects of abandoned coal mine ecological restoration on soil quality and function is important to protect the regional ecological environment. This study aims to evaluate the ecological restoration effects of soil quality in abandoned coal mine area. Taking Fengcheng County, a typical coal‐rich area in southern China, as a case, this study took 120 soil samples to investigate the influence of restoration years on soil quality by using an integrated soil quality index (SQI). Results indicated that restoration years had significant effects on the saturated hydraulic conductivity (Ks) by affecting the soil bulk density, clay content, and soil water content. Furthermore, clay, soil organic matter, Ks, and pH were selected to assess the effect of ecological restoration years on soil quality. It was found that the ecological restoration 8 years (ER8) site had higher SQI value, indicating ecological restoration years showed a positive correlation with SQI in abandoned coal mine area. Since there was a 4‐year gap between ecological restoration 4 years site and ER8 site, the ecological restoration may be effective between 5 and 8 years. The results of this study are of great significance for improving the effects of ecological restoration and management in abandoned coal mine area.
