Perforated plate ventilation system and dynamics of infectious respiratory particle transmission

AbstractWith the removal of indoor pollutants and the assurance of air quality emerging as critical research topics, the optimization of the internal environment in offices, where people stay for extended periods, is essential for controlling the spread of infectious respiratory particles. Frequent movements of personnel and the operation of doors and windows within offices significantly impact the mechanisms of droplet transmission, warranting further investigation. This study employs computational fluid dynamics simulations to explore the droplet dispersion characteristics and pollutant removal efficiency of the simplified model of perforated plate ventilation system (PPVS) (the diameter of the air supply openings has been reasonably simplified and uniformly set to 0.02 m) in office settings, as well as the impact of dynamic door operation scenarios on droplet spread and concentrations in breathing zones. To optimize the ventilation system's pollutant removal efficiency, airflow velocities (2.86, 3.18, and 5.00 m/s) are varied, with simulations conducted at the optimal velocity of 3.18 m/s. The effects of continuous door operations, door‐opening directions (towards the office and towards the isolation room), and opening speeds (π/4, π/6, π/8, and π/10 rad/s) are also examined, revealing significant impacts on droplet spread. Results indicate that PPVS effectively reduces indoor pollutant concentrations at all tested airflow velocities, with the optimal speed identified as 3.18 m/s. Additionally, door‐opening direction and speed can significantly influence droplet spread. Opening doors towards isolation rooms at smaller angles (less than 30°) effectively reduces droplet concentrations in personnel breathing zones, thereby mitigating the risk of droplet transmission. Faster door‐opening speeds also contribute to lower droplet concentrations in these zones. This innovative study explores the impacts of PPVS and dynamic door operation dynamics on droplet transmission during respiratory disease outbreaks, providing valuable theoretical insights and technical support for disease prevention and indoor air quality improvement.

Research on the Constructed-Wetland/Regulation-Tank System at Pontificia Universidad Javeriana's Bogotá Campus

The stormwater harvesting (SWH) project at Pontificia Universidad Javeriana (Bogotá) began in 2007, initiated by the Water and Environmental Engineering research group (Ciencia e Ingeniería del Agua y el Ambiente), as part of PUJB's Environmental Management Plan and in collaboration with the University's Office of Physical Resources. This process included assessments of water supply and demand, rainwater quality, and financial and construction considerations. The system—a constructed wetland/regulation tank (CWRT)—collects rainwater runoff from the university's parking building (3,776 m²), the soccer field, and surrounding areas (14,816 m²). Beyond its hydrological performance, especially during periods of water scarcity, the system also functions as a full-scale laboratory to study biodiversity and ecological impacts in hydrological and hydraulic processes. The monitoring program, focused on changes in rainwater quantity and quality, has inspired several master's and doctoral research projects. These studies explore critical topics in urban hydrology, including stormwater harvesting, urban sediment management, real-time decision-making systems, and environmental and human health. This paper outlines the development of the stormwater harvesting system, shares the main findings from research projects, and discusses ongoing projects.

6.M. Scientific session: Risk And Resilience Factors Of Mental Health During COVID: European Multi-country Data Findings

Abstract The COVID-19 pandemic significantly affected mental health. It worsened the mental health and well-being of those already vulnerable or exposed to excess pandemic-related stress. In addition, lockdowns and other measures created additional obstacles to mental health support access. In response, the European Commission funded the RESPOND project in 2020, aimed at enhancing the preparedness of mental health systems for pandemics and global crises. As part of the RESPOND project, (meta-)analyses were conducted on prospective cohort datasets, national health register data, and multi-country individual participant data (IPD). The aim was to examine whether there was a change in prevalence rates of mental health conditions (e.g., anxiety and depression) in the general adult population of the EU during, compared to before and in between, the COVID-19 pandemic waves. Analyses on risk factors (e.g. sociodemographic- and economic factors, severity of COVID-19 infection, (lack of) social activity and support, and loneliness) associated with psychological distress and mental disorders as well as resilience and well-being (coping strategies and core value orientations) in the general population or specific vulnerable groups were conducted as well. This workshop will feature five talks covering various aspects of the RESPOND epidemiological analyses. First, an introduction and rationale of the RESPOND study on short- and long-term impacts of the COVID-19 pandemic and outbreak response, will be provided. Subsequently, findings from the multi-country longitudinal COvid MEntal healTh Survey (COMET) on forecasting psychological distress throughout the pandemic will be presented. Second, findings from the French TEMPO (Trajectoires EpideMiologiques en POpulation) cohort and merged datasets will be presented indicating associations and interactions between socioeconomic factors, mental health, and public health behaviours during the pandemic. Third, using data of a large Belgian prospective cohort, fluctuations in risk of psychological distress across study waves and the factors associated with individual trajectories of psychological distress during the COVID-19 pandemic will be presented. Fourth, the risk of SARS-CoV-2 infection, severe COVID-19 outcomes, and death among individuals with various mental disorders, based on Spanish health records, will be presented with specific attention to sex differences. Finally, based on the IPD meta-analyses of 9 European cohorts, findings on stressor reactivity, resilience trajectories, and factors associated with resilient outcomes and vulnerability are presented. By presenting a selection of findings from large datasets together, we aim to facilitate discussions on critical topics such as vulnerability and resilience to mitigate mental health impacts in future public health crises. Key messages • Targeting specific individual vulnerabilities appears to be more effective in reducing the pandemics’ mental health impact than solely responding to pandemic-related fluctuations. • Research and harmonised data on vulnerability and resilience factors are essential for guiding the development of targeted interventions and support systems for vulnerable populations during crises.

The knowledge layer: the role of key messages for translating data into meaning

Abstract The large volume of data generated by health information systems often remains siloed within the institutions that produce it, posing significant challenges to its reuse and interpretation. This fragmentation can result in conflicting information on critical health topics, complicating the decision-making process for policymakers. To address this issue, Belgium has initiated the ‘Health Status Report’ website, hosted at healthybelgium.be. This website aims to synthesize and present health data in a manner that supports evidence-based policy formulation. The website adopts a structured approach to data integration and interpretation: initially, we identify and prioritize key health topics based on their relevance and the quality of available data. Subsequently, we merge and analyze data from diverse sources to discern patterns and trends that are crucial for public health monitoring. The insights gained are then presented through both narrative texts and interactive visualizations, facilitating access and understanding for a broad audience. Crucial to this process is ongoing communication with experts and stakeholders, ensuring that the data is not only accurately interpreted but also aligns with the needs and expectations of its users. We also aim to translate the raw data into meaningful key messages by consulting with internal and external experts. This interactive platform thus serves as a critical tool for translating complex health data into actionable knowledge, enabling informed public health strategies and interventions.

Advancing Knowledge in Forest Water Use Efficiency Under Global Climate Change Through Scientometric Analysis

Forests are critical in regulation of carbon and water cycles and mitigation of climate change. Forest water-use efficiency (WUE) refers to the ratio of biomass produced (or assimilated carbon) to the amount of water used by forests, which indicates how effectively a forest utilizes water to achieve productivity. Climate change and its impact on forest WUE are important research directions that explore the complex relationship between global environmental change and the forest ecosystem dynamics. The global intensification of climate change underscores the need for an inclusive understanding of forest water use and makes it crucial to know how forests balance carbon and water resources, which is essential for effective forest management and predicting ecosystem responses to climate change. This study aims to comprehensively and objectively analyze current research trends and future directions related to the response of forest WUE to climate change. Our database included 1755 research papers from the Web of Science Core Collection, spanning from 2000 to 2023. Our analysis included cooperative networks of countries, authors, and institutions, as well as the most frequently cited journals and articles, keyword co-occurrence analysis, and a keyword burst analysis. The results showed that the top cooperative country, author, and institution is PR China, Prof. Dr. Jesús Julio Camarero from the Consejo Superior de Investigaciones Científicas (CSIC), and the Chinese Academy of Sciences, respectively. The leading journal in this field is “Global Change Biology”. Critical research hot topics include gas exchange, modeling, altitudinal gradients, tree growth dynamics, net carbon exchange, global change drivers, tropical forests, nitrogen stoichiometry, Northern China plains, and extreme drought conditions. Frontier topics that have emerged in recent years include studies on China’s Loess Plateau, stable isotopes, radial growth, gross primary productivity, and Scots pine. The insights from this analysis are vital for researchers, decision-makers, and forestry professionals aiming to mitigate the impacts of climate change on forest WUE and overall ecosystem health and resilience. This study emphasizes the importance of sustained research efforts and global research collaboration in addressing the intricate challenges posed by climate change to forest ecosystems.

“It Can't Just Be the Younger People”: Exploring Young Activists' Perspectives on Intergenerational Tensions and Solidarities for Climate Justice

ABSTRACTYouth activism for climate justice is inherently intergenerational. Fundamentally, young activists demand urgent action by today's adult power‐holders for the security and well‐being of their own and future generations. Despite intergenerationality being core to the movement, few studies with young activists have explored their views and experiences of intergenerational relations and tensions and how to advance intergenerational solidarities for climate justice. Addressing these critical topics, the present study used in‐depth interviews with young activists (ages 15–17) in the climate justice movement across the US. Themes generated through reflexive thematic analysis centre on: (1) youths' adoption of “next generation” and “last generation” identities, respectively emphasising the heightened climate risks faced by their own and future generations, and the closing window of opportunity to prevent catastrophic climate breakdown; (2) their experiences of hostile and benevolent adultism; and (3) the need for adults to listen to, take seriously, centre, amplify, and—most importantly—respond to youths' demands. They urge adults, particularly those in powerful positions, to use their age‐based privilege, political enfranchisement, material resources, professional status, and decision‐making authority to uplift young people's voices and tangibly advance climate justice through solidarity‐driven intergenerational partnerships and action. Implications for youth‐centred research and policy are discussed.

Leverage Effect of New-Built Green Spaces on Housing Prices in a Rapidly Urbanizing Chinese City: Regional Disparities, Impact Periodicity, and Park Size

While newly built urban green spaces aim to address environmental concerns, the resulting green gentrification and social inequality caused by escalating property values have become critical topics of urban socio-spatial research. To prevent green initiatives from becoming unaffordable for their intended beneficiaries in rapidly urbanizing cities, it is essential to examine the spatial and temporal relationships between the construction of new green spaces and rising housing prices. This study employs a difference-in-differences methodology to analyze regional disparities, impact periodicity, and the influence of park size on housing prices, using Nanjing, China as a case study. This result reveals that the introduction of new-built parks in Nanjing significantly impacts housing prices within an 800 m radius. The premium effect of these parks is substantially higher in urban core areas compared to suburban locales, demonstrating spatial differentials. Suburban parks temporally exhibit a prolonged lag and a shorter premium impact duration. Moreover, among various park areas, medium-sized parks demonstrate the most pronounced leverage effect, approximately double that of large parks, while small parks do not significantly affect housing prices. To mitigate the exacerbation of premium effects and enhance social justice in green strategies, we advocate prioritizing the development of small parks, particularly in urban core areas, and leveraging the temporal delay in new-built park impacts for urban policy interventions.

Electronic brake system-based hierarchical motion control of commercial vehicle for autonomous obstacle avoidance

As a high-level autonomous driving technology, efficient and safe automatic obstacle avoidance on highway is one of the critical and ongoing topics that requires in-depth research for commercial vehicles. Electronic control air pressure brake system, owing to its fast response and active braking ability, is an effective active-chassis technology to function path tracking and stability control in such condition. Yaw motion stability control problem of autonomous driving commercial vehicle based on active braking control with electronic air brake system for automatic obstacle avoidance is investigated. First, a hierarchical yaw motion dynamics control architecture is introduced after vehicle and brake system modeling. The quintic polynomial curve-based trajectory planning method and a Model Predictive Control based trajectory tracking control strategy are formulated. Second, to evade the possible stability losing issue in this circumstance, Cubature Kalman Filter (CKF) is utilized to estimate the vehicle motion states, and a fuzzy PID control-based differential brake stability control strategy is designed for the electronic brake system composed of front-and-rear two sets of dual-channel pressure regulator and ABS solenoid valve. Finally, the proposed hierarchical yaw stability control strategy for a commercial vehicle in typical obstacle avoidance conditions is comparatively verified based on the joint simulation tools. After the yaw stability control, the peak value of the lateral displacement error of trajectory tracking can be reduced by 44.7%. The yaw stability control strategy based on fuzzy PID control can reduce the yaw rate by 46%–57% and the sideslip angle by 60%–73% under different conditions. The results show that the proposed control strategy can effectively improve the yaw stability of the vehicle while avoiding obstacles at high speed.

HYDROTHERMAL SYNTHESIS OF NITROGEN-DOPED CQDS OF RUBUS NIVEUS LEAVES FOR FLUORESCENT pH SENSING AND PHOTOCATALYTIC APPLICATIONS

The development of a fluorescent pH sensor and the treatment of wastewater with nanoparticles are both critical topics. The variation in pH impacts the morphology and subsequent properties of the nanoparticles, which are used for their utilization in various fields and the second one gives a better treatment approach for industrial waste entities. The present study examines the effects of these variables on the biologically produced nitrogen-doped carbon quantum dots (NCQDs). Hydrothermal process was performed for the synthesis of the same by using Rubus-niveus leaf extract as a precursor. The UV-Vis spectroscopy analysis shows absorption spectra in the wide range of 200 nm to 800 nm and shows prominent peaks at 236 nm and 392 nm, respectively. Further, the direct energy band gap of 3.65eV was analysed for NCQDs. The SEM image shows flower-shaped particles, and FT-IR analysis indicates the existence of amide, CHO, N-H, and C-N functional groups. XRD pattern showed that the surface morphology of NCQDs is amorphous in nature. A good response was found in the variation of fluorescence intensity with the pH values, confirming the possibility of NCQDs serving as pH sensors. Rhodamine-B (Rh-B) dye's reaction kinetics was revealed for the purpose of analyzing the potential of NCQDs for the degradation of commercial dyes and found to be followed by pseudo-first order kinetics with the correlation coefficient of 0.80.

Energy dissipation performance of labyrinth and harmonic stepped spillways

ABSTRACT Stepped spillways are structures that dissipate the energy on steps, especially in topography, where building the energy dissipate pool is impossible as long as required. For this reason, stepped spillways are one of the critical topics that have attracted the attention of researchers for many years. It has been the subject of many studies, especially because the step geometry is an effective parameter in the energy dissipation rate. In this study, the effect of the labyrinth and harmonic geometry on the plan on energy dissipation performance is examined using the open-source OpenFOAM software. The 11 different geometries were analyzed in detail and discussed with the literature results. For analysis, the k − ω SST turbulence model and the multi-phase solver interFoam were utilized. The results showed that the number of cycles is an effective parameter for energy dissipation performance; the energy dissipation rate increases when effective crest length increases, and labyrinth and harmonic models could dissipate about 20% more energy than the flat model.

MAPPING WHISTLEBLOWING THROUGH THE ROLE OF WHISTLEBLOWERS: A BIBLIOMETRIC ANALYSIS

This study explores whistleblowing's role in addressing fraud and corruption in Indonesia. Using bibliometric analysis, we examined publication trends, document types, subject areas, influential authors, and critical topics in whistleblowing research from 2014 to 2023. Data were collected from the Scopus database, analyzed with the Publish or Perish application, and visualized using a VOS viewer. The results show that articles dominate the field, making up 80.25% of total citations. The findings have significant implications for policymakers, practitioners, and academics. It is a beneficial overview of whistleblowing research, but it only needs to be better and measured based on these findings. These insights do not offer actionable guidelines or strategies but work as, at most, a compass map of existing research trends and areas of interest in whistleblowing discussions. However, the lessons could form a valuable database for anyone to understand the current status of the research ecosystem. However, more than insights alone need to be directly translated into practical designs or applications like building up a system for whistleblowing and anti-fraud, et cetera, which would require further (more applied) studies.

Bibliometric analysis of microRNAs and Parkinson's disease from 2014 to 2023.

Parkinson's disease (PD) is a neurodegenerative disorder characterized by the degeneration of dopaminergic neurons. Recent research has emphasized a significant correlation between microRNAs (miRNAs) and PD. To identify key research areas, provide a comprehensive overview of current research in various fields, and propose potential directions for future studies, a bibliometric analysis was conducted on the involvement of miRNAs in Parkinson's disease from 2014 to 2023. Relevant literature records were collected from the Web of Science Core Collection on February 29, 2024. Subsequently, the data underwent analysis using the Bibliometrix R package and VOSviewer (version 1.6.19). The annual scientific publications on miRNAs and Parkinson's disease demonstrated an increasing trend, with an annual growth rate of 12.67%. China, the United States, and India emerged as the top three most productive countries/regions. The University of Barcelona had the highest annual publications, followed by Central South University and the Helmholtz Association. The INTERNATIONAL JOURNAL OF MOLECULAR SCIENCES held the top position in terms of H-index and total citations, reflecting its extensive influence and prolific publication output. Kim, J., Junn, E., Hébert, S.S., and Doxakis, E. were the most frequently co-cited authors in the field. Based on the analysis of keywords, the most frequently occurring terms included "alpha-synuclein," "neurodegenerative disease," "exosome," "neuroinflammation," "oxidative stress," "autophagy," and "amyotrophic lateral sclerosis," which have emerged as prominent research topics. Concurrently, there has been notable interest in topics such as "ceRNA," "lncRNAs," "mitochondrial dysfunction," and "circular RNA." This study focused on identifying emerging trends and critical research topics in the bibliometric analysis of microRNAs related to Parkinson's disease. These findings highlight the diverse research landscape and evolving trend of miRNA-related research in PD. The field of miRNA research in Parkinson's disease is actively exploring the underlying mechanisms of miRNA function, identifying potential diagnostic markers, and developing innovative therapeutic strategies. The results of our study offer significant contributions to researchers' ability to track contemporary developments and guide the trajectory of future research in this domain.

Abstract B084: Multi-Stakeholder Engagement to Create Equity in Prostate Cancer Outcomes through Identifying Community Priorities in Early Detection Research

Abstract Introduction: Black individuals have a two-fold higher rate of prostate cancer death in the US compared with other groups. This is the largest racial inequity in US cancer-related deaths. Annual prostate-specific antigen (PSA) testing among Black individuals starting at age 45 years could reduce mortality by 30% compared with current screening practices. Few current practice guidelines make race-conscious screening recommendations due to a lack of trial data on screening in Black populations; only 0-3% of participants in practice-informing PSA screening trial cohorts were Black. An equity-informed approach is required to ensure that trial designs reflect the priorities and perspectives of Black individuals to ensure their participation in future research. Methods: We partnered with the Black and African-descent Collaborative for Prostate Cancer ACtion (BACPAC) to conduct a survey to identify community priorities in prostate cancer early detection research. Respondents were asked to rate the importance of 15 research topics, then select the three topics most critical for research. Members of the BACPAC Virtual Research Community (VRC), a nationally representative group of 2,016 Black prostate cancer survivors and community members, were invited to participate. Eligible members were Black prostate cancer survivors and family members/caregivers of Black prostate cancer survivors. Those who met the inclusion criteria were emailed a unique link to complete the online survey. Results: 1,557 eligible VRC members received a survey link, 1,224 surveys were completed (78.6% response rate). 60% of respondents were survivors, 38% were family members/caregivers, and 2% were both. More than 80% of respondents rated each of the 15 research topics as moderately to very important. Topic rankings revealed two overarching priority areas, representing 6 out of 15 topics included in the survey. These areas were 1) the use of reflex testing in the setting of elevated PSA to aid detection of clinically significant cancer and 2) establishing optimal timing for initiation or interval of PSA testing for prostate cancer screening. Regarding use of reflex testing, 97.7% of respondents prioritized blood (44.3%), urine (27.8%), or MRI (25.6%) reflex testing. Regarding timing of PSA testing, 51.5% of respondents prioritized customized screening schedules based on personal risk factors, with 24.9% selecting to improve rates of screening and 26.6% selecting to improve detection of clinically significant cancers, and 25% of respondents prioritized initiating screening at age 45 to improve early detection of prostate cancer. Conclusion: Our survey identified critical research topics that are of high importance to Black prostate cancer survivors and their families/caregivers. Our findings bridge a critical gap in prostate cancer early detection research, from which Black individuals have been historically excluded. Involving Black prostate cancer survivors in research design may help ensure that Black individuals are better represented in future clinical trials. Citation Format: Jenney R.

Development of a Prioritized Anesthesiology Residency Critical Care Content Outline.

Critical care education is an important, mandatory component of residency training in anesthesiology. Currently, there is no accepted national standardized curriculum, and a prioritized critical care content outline would be beneficial to the creation of a pragmatic standardized residency curriculum. The modified Delphi method is a recognized method for establishing consensus in medical education. We developed a prioritized critical care content outline using the modified Delphi method. Topics were selected from critical care topics included in the Program Requirements for Graduate Medical Education in Anesthesiology and the American Board of Anesthesiology Content Outline. Panel members rated critical care topics on a 9-point Likert scale (1 = not important, 9 = mandatory). Consensus was defined as ≥75% rating the topic as very important to mandatory for inclusion (Likert scale 7-9). Topics with >80% consensus were removed from subsequent surveys and included in the final list, and topics with <50% were removed. Members were asked to select the ideal timing of topic delivery during residency (Foundational-Early Residency, Intermediate-Mid Residency, Advanced-Late Residency). A total of 158 panel members who were contacted using national anesthesiology organization email lists completed the initial round, 119 (75%) completed the second iteration, and 116 (73%) completed the third. Response rate on the first survey was (22/55) 40% for anesthesiology critical care program directors, (18/132) 14% for core anesthesiology residency program directors, and (77/1150) 7% for the remaining respondents. Trainees (n = 41) were not included in response rate calculations. Most participants (103/158, 65%) had completed both core anesthesiology and subspecialty critical care medicine training and most (87/158, 55%) had formal roles in medical education. Forty-one (26%) responders were currently in training. All panelists worked in institutions with graduate medical education (GME) learners. Fifty-eight of 136 (43%) topics met consensus for inclusion. Most consensus topics (50/58, 86%) were recommended to be delivered early during residency with the other 8 topics to be delivered in the middle of residency. We developed a prioritized critical care content outline for anesthesiology residents that includes highly recommended critical care topics with ideal timing for inclusion in residency. This outline provides the first step in developing a pragmatic standardized curriculum to guide faculty and programs in critical care education.

Gauging Airbnb review sentiments and critical key-topics by small area estimation

In literature, several researchers have discovered that the reviews written about Airbnb accommodation tend to be extremely positive than those published on other famous platforms, consequently, many negative experiences remain untracked. Leaving negative experiences underrepresented hampers hosts’ ability to improve their services. To overcome this gap, we employ Small Area Estimation to quantify negative sentiment in Airbnb reviews and the relative critical topics that characterize them. Our methodology involves a two-step process: first, we employ sentiment analysis and topic modeling to identify negative sentiment and critical issues, followed by the application of a mixed effect random forest model to provide a granular analysis of Airbnb reviews in small sub-populations in the context of small area estimation. We focus on domains of the city of Rome defined by geographical areas and the presence of hosts and Superhosts. Our findings reveal nuanced sentiment variations and critical topic proportions that traditional methods often overlook.

The challenges and opportunities of researching masculinities during peace processes

ABSTRACT This article introduces a special issue in Peacebuilding on researching masculinities during peace processes. It collates insights from feminist peace research, and research on gender and masculinities, to highlight how peace processes are necessarily also processes of gender re-negotiation and transformation. We argue that researching masculinities entails accounting for their plural circulation, complex and contradictory dynamics, and multiple effects. Researching masculinities additionally generates methodological dilemmas that require researchers’ reflexive engagement. The articles in the special issue address critical themes and topics pertaining to masculinities and peace across a wide range of participant experience in diverse contexts (including Bosnia, Indonesia, Liberia, Timor-Leste, Uganda, and the UK). We summarise authors’ critical and empirical contributions and chart their methodological innovations and strategies. We see plural masculine performances and identities not as obstacles to be overcome in/through research but as opportunities to generate discussion with research participants about the operability and impacts of gender.

Unlocking the potential of blockchain-based sharing economy in hospitality and tourism: A systematic review

This systematic review is a trailblazer for the blockchain-based sharing economy concept, mainly in hospitality and tourism. It highlights the potential integration of blockchain across sharing economy sectors (e.g., accommodation, transportation, and business services). Following the PRISMA protocol, 43 publications from 12 scholarly databases were analysed. It identifies different types of implementations, including decentralised apps and specific functionalities that utilise blockchain. Key issues are discussed, including contradictory aspects (transparency vs privacy, centralisation within decentralisation, and users' euphoria vs technical barriers) and advantages (increased security, automated sharing mechanisms, and user participation). The review offers practical implementation paths for blockchain-based sharing economy systems in hospitality and tourism, emphasising the importance of context, scope limitation, focusing on increasing advantages, and managing technological trade-offs. It also suggests critical future research topics and action agendas for hospitality and tourism stakeholders.
