USE OF FLOATING (PONTOON) BRIDGES FOR THE ENGINEERING COVER OF TRANSPORT FACILITIES

Purpose. The purpose of this work is to investigate the topic of floating (pontoon) bridge systems as an option for overcoming water obstacles, a means of technical cover for national transport infrastructure facilities, and to analyze the current state of application of existing floating system property in order to determine the directions of further research in this area. Methodology. Research of existing floating (pontoon) bridge systems, their classification and technical characteristics, in the context of means of technical cover of important transport facilities and overcoming water obstacles in the conditions of modern warfare. Findings. Provision of temporary pontoon bridges is carried out during the creation of duplicate bridge crossings (ferry crossings) and the restoration of traffic in areas with destroyed transport facilities. Pontoons from sets of floating bridges can be used as platforms for installing special construction equipment during the construction (restoration) of transport facilities. A systemic analysis of floating (pontoon) bridges as an option for overcoming water obstacles for the technical cover of transport infrastructure facilities was conducted. All available floating (pontoon) means that can be used for their intended purpose were considered, and the need for modeling floating (pontoon) systems to expand their application possibilities was determined. Originality. The scientific interest lies in the fact that after conducting an analysis of the classification and technical characteristics of the available means of floating (pontoon) bridge systems, the main directions for further research and their simulations have been established, which will create conditions for their optimized application, taking into account the challenges of today in overcoming wide water obstacles, technical cover objects of the national transport infrastructure by laying duplicate temporary floating bridges (ferry crossings). Practical value. Pontoon systems for bridges are essential for providing technical cover for national transport infrastructure objects. Given the limited number of identical systems available for pontoon bridge systems, it is relevant to research the adaptation of different pontoon systems in one crossing, thereby expanding their application possibilities and providing all the necessary conditions for overcoming the widest water obstacles in Ukraine.

Perspectives of Digital Health Innovations in Low- and Middle-Income Health Care Systems From South and Southeast Asia.

Digital health innovations have emerged globally as a transformative force for addressing health system challenges, particularly in resource-constrained settings. The COVID-19 pandemic underscored the critical importance of these innovations for enhancing public health. In South and Southeast Asia, a region known for its cultural diversity and complex health care landscape, digital health innovations present a dynamic interplay of challenges and opportunities. We advocate for ongoing research built into system development and an evidence-based strategy focusing on designing and scaling national digital health infrastructures combined with a vibrant ecosystem or "marketplace" of local experiments generating shared experience about what works in which settings. As the global digital health revolution unfolds, the perspectives drawn from South and Southeast Asia-including the importance of local partnerships-may provide valuable insights for shaping future strategies and informing similar initiatives in low- and middle-income countries, contributing to effective digital health strategies across diverse global health contexts.

An information-theoretic analysis of security behavior intentions amongst United States poll workers.

In light of recent events related to national elections in the United States, safeguarding the security and integrity of forthcoming elections stands as a critical national priority. Elections equipment in the United States constitutes critical national infrastructure, and its operation relies on poll workers, who are trusted insiders. However, those insiders may pose risks if they make mistakes with detrimental consequences or act with malice. This research analyzes a large dataset of 2213 responses obtained from a survey of poll workers and potential poll workers in 13 states. The survey includes the Security Behavior Intentions Scale, which has been previously established and validated in the security literature. We use the responses to assess poll workers' intentions of complying with established security-related practices. We develop a novel model using information theory to examine potential weaknesses in security behaviors and identify poll worker security practices to improve to ensure the integrity of our elections. We also recommend action items and countermeasures for states and localities based upon this empirical analysis.

Optical soliton noninteraction transmission in optical communication systems

The building of the national communication infrastructure and growing demand for data traffic both depend heavily on the advancement of optical soliton communication technology. In particular, by studying the interaction of optical solitons, some methods of controlling optical solitons can be explored to design more stable and efficient optical communication systems. In this paper, the interactions between optical solitons are studied based on the theory of generalized Schrödinger–Hirota equation. By studying the amplitude ratio, spacing and phase difference of the optical solitons, the interactions between the optical solitons occurring in the optical fiber transmission process are attenuated. The noninteraction transmission of optical solitons are realized with small spacing between them. The conclusions of this paper are not only of great significance for the in-depth understanding of the nature of optical soliton interactions, but also of great practical value for promoting the application of optical solitons in optical communications and other fields.

Analysis of High-Voltage Holding Capability for CRAFT NNBI Negative Ion Source with 400 kV

CRAFT (Comprehensive Research Facility for Fusion Technology) is a large scientific device that is preferentially deployed for the construction of major national science and technology infrastructures. A negative ion–based neutral beam injection system with a beam energy of 400 keV, a beam power of 2 MW, and a beam duration of 100 s, it was designed to deliver an energetic neutral beam for fusion research. Among the crucial components of this system, the high-power negative ion source stands out, and the voltage holding capability of its accelerator with double-stage is a commonly encountered issue. To address this concern, a comprehensive investigation has been conducted that focused on the gaps between the acceleration grids and grid supports in terms of voltage holding capability utilizing empirical formulas. The results of this investigation revealed that an acceleration gap of 81 mm and a grid support gap of 65 mm can be achieved through the implementation of empirical formulas, which aligns with the requirement of 200 kV for each stage. In addition, the preliminary experimental results showed that the voltage holding capability of the adjacent grids can reach up to 200 kV when the gap between the adjacent grids was designed to be 90 mm. These findings provide a foundation for the subsequent design of a high-power ion source characterized by both high energy and a large area.

Diversity in Family Medicine Research.

In conjunction with the North American Primary Care Research Group (NAPCRG) Annual Conference in 2023, leaders in the field of family medicine came together to discuss and produce a Family Medicine Research Agenda. While multiple areas were discussed, diversity, equity, and inclusion did not rise to the top as research priorities. This article discusses the 3 areas family medicine leaders see as necessary to produce high-quality research. The authors present ideas on how diversity, equity, and inclusion can be prioritized in each area. In the first area, "Grow the family medicine research workforce by expanding pathways and strengthening mentorship," the authors present existing models, with an emphasis on those pathway programs proven to increase scholarship and research, such as the Leadership Through Scholarship Fellowship sponsored by the Society of Teachers of Family Medicine (STFM) and the Building Research Capacity Program sponsored by the Association of Departments of Family Medicine (ADFM). In the second area, "Increase funding for family medicine research and advocate for enhanced health policy and support," the authors present ideas on greater utilization of NIH diversity supplements as well as institutional advocacy by family medicine chairs to create seed grants and provide opportunities for diverse faculty to engage in research. Chairs can also increase the diversity of the researcher pool by recruiting among local full-time clinicians, a more diverse group than most faculties. For the final area, "Build a national infrastructure for organizing and optimizing family medicine research opportunities," the authors present solutions including following demographic data surrounding authorship and reviewing for journals; having dedicated committees or editors focused on diversity, equity, and inclusion; and using demographic data from conference submissions to encourage those from underrepresented backgrounds to translate their presentations into a manuscript. These strategies can help equity, diversity, and inclusion become central to our research and be used as a national model for other specialties attempting to do the same.

Experimental Study on the Acceleration Amplification Ratio of Cable Terminations for Electric Power Facilities

Among national infrastructure facilities, electric power facilities are very important sites that must maintain their functions properly even during a natural disaster or during social crises. Therefore, seismic design is required when necessary for major electric power facilities that have a significant impact when damaged in the event of an earthquake. In electric power facilities, bushings are generally installed in devices or structures. Therefore, ground acceleration can be amplified through devices, such as transformers, or sub-structures. Among various electric power facilities, cable terminations are representative cantilever-type substation facilities consisting of a bushing, a sub-structure, and support insulators. The bushings of cable terminations are generally made of porcelain or fiber-reinforced plastic (FRP) materials, and they may have different dynamic characteristics. This study attempted to estimate the acceleration amplification ratio in the main positions of cable terminations considering the materials of bushings. For two cable terminations with different specifications and bushing materials, three-axis shake table tests were conducted in accordance with IEEE 693, which includes a seismic performance evaluation method for a power substation facility. The acceleration amplification ratios at the top of the bushing, mass center, and top of the support structure were estimated using the acceleration responses of each cable termination. They were then compared with the acceleration amplification factors presented in design standards. Consequently, the acceleration amplification ratio of cable termination with an FRP bushing was lower than that of the cable termination with a porcelain bushing.

Science in times of war: reflections from Sudan

The war that erupted in Sudan on 15th April 2023 between the Sudanese Armed Forces (SAF) and Rapid Support Force (RSF) resulted in widespread destruction of national infrastructures, including the educational and research systems. Based on the personal experiences of the authors, this paper discussed the impact of the war on science and community of scientists who remained in Sudan during the war, including the resultant challenges, opportunities offered, and future perspectives. Clearly, the war brought about unquantifiable devastation on professional and personal lives of scientists; internal and external displacement and separation of scientists, colleagues, and families; loss of research and teaching resources; loss of jobs and financial instability; and host of negative psychological, emotional and social issues. Given that more than 10.4 million Sudanese were forcibly displaced, among them scientists, the educational system has been hampered. Available data indicate that in Khartoum State, 39% of governmental and 73% of non-governmental universities were occupied by RSF, whereas it was 10% of governmental and 8% of non-governmental universities in Gezira state. This contrasts with 3% of governmental and 5% of non-governmental university in South Darfur. Some universities and colleges were partially or completely damaged, while in some it was not possible to determine the damage. This has led to complete shutdown of the universities, forcing students to find expensive alternative ways to continue their education or abandon it altogether. Scientists and science in Sudan faced many challenges, which are difficult to overcome. While efforts to restore infrastructure and physical capital will be challenging, the social, psychological, and emotional devastation might be even more intricate. Revitalizing policies and international efforts are needed to support the recovery of the entire educational systems and research infrastructures, as well as the wellbeing of scientists.

National biodiversity data infrastructures: ten essential functions for science, policy, and practice

Abstract Today, at the international level, powerful data portals are available to biodiversity researchers and policymakers, offering increasingly robust computing and network capacities and capable data services for internationally agreed-on standards. These accelerate individual and complex workflows to map data-driven research processes or even to make them possible for the first time. At the national level, however, and alongside these international developments, national infrastructures are needed to take on tasks that cannot be easily funded or addressed internationally. To avoid gaps, as well as redundancies in the research landscape, national tasks and responsibilities must be clearly defined to align efforts with core priorities. In the present article, we outline 10 essential functions of national biodiversity data infrastructures. They serve as key providers, facilitators, mediators, and platforms for effective biodiversity data management, integration, and analysis that require national efforts to foster biodiversity science, policy, and practice.

Publishing and using parliamentary Linked Data on the Semantic Web: ParliamentSampo system for Parliament of Finland

This paper presents a new infrastructure and semantic portal called ParliamentSampo for studying parliamentary speeches, culture, language, and activities in Finland. For the first time, the entire time series of some million plenary speeches of the Parliament of Finland (PoF) since 1907 have been converted from text into knowledge graphs and data services in unified formats, including CSV, Parla-CLARIN, ParlaMint, and RDF Linked Open Data (LOD). The speech data have been interlinked with a semi-automatically created ontology and a knowledge graph about the activities of over 2800 Members of Parliament (MP) and other speakers in the plenary sessions of the PoF. The data was enriched by data linking to external data sources and by reasoning into a broader LOD service. Knowledge extraction techniques based on Natural Language Processing (NLP) were used for automatic semantic annotations and topical classification of the speeches. The data and data services have been used in Digital Humanities (DH) research projects and for application development, especially for developing the in-use semantic portal ParliamentSampo. The infrastructure and the portal were published on February 14th 2023 on the Web using the open CC BY 4.0 license, and quickly gathered thousands of users, including citizens, media, politicians, and researchers of politics. ParliamentSampo is a new member in the “Sampo” series of over 20 interlinked LOD services and semantic portals in Finland, based on a national Semantic Web infrastructure. Although the paper uses Finnish parliamentary data as a case study, the approach, methods, and tools presented can be adapted also to other parliamentary datasets in other countries.

Health policy analysis for stewardship of rehabilitation services

Background and aimThere have been a growing interest in investigating the effect of stewardship on other functions of rehabilitation service delivery. Effective stewardship of rehabilitation services can ensure that these services are of high quality, accessible, affordable, and sustainable, and can help achieve the goals of universal health coverage. The purpose of this study was to identify and analyze the policies adopted in the field of rehabilitation services in Iran and in the international arena, and finally to identify policy gaps, areas for improvement, and areas that have been overlooked.MethodThis research is a policy analysis, carried out through document analysis and Dalglish et al.’s READ approach. Data were analyzed and interpreted using qualitative methodology and directed content analysis. For this purpose, Veillard et al.‘s health system stewardship framework was used to analyze the stewardship of rehabilitation services. The dimensions of the stewardship framework, were: Defining the vision for health and strategies and policies to achieve better health; influencing all sectors and advocating for better health; ensuring good governance in line with prevailing values; ensuring the alignment of system design with health system goals; improving existing legal and regulatory instruments; and compiling, disseminating, and applying information. Scott’s four criteria were used to assess the authenticity, credibility, representativeness, and meaning of the documents. Those that did not meet even one of the Scott’s criteria were excluded from content analysis.FindingsA total of 16 documents were identified, all of which met Scott’s criteria and none were excluded from the study. A total of six themes and 56 subthemes were extracted. The contents of all the documents were extracted under six themes of Veillard et al.‘s health system stewardship framework. Overall, the results show that national documents place greater emphasis on the development of preventive healthcare and health promotion. Documents often focus on engaging NGOs and the families of people with disabilities and on intersectoral collaboration for knowledge production and the development of intersectoral knowledge networks. In terms of health system governance in line with prevailing values, documents are mainly focused on health system stewardship by the Ministry of Health and on evidence-based decision-making with the participation of target groups. Also, documents place more emphasis on upgrading the national infrastructure and increasing access to rehabilitation services.ConclusionIn some areas of rehabilitation services, there is a gap between national documents, which reflects differences in priorities, approaches, resources, and instruments available to strengthen rehabilitation services at the national and international levels.

10.I. Scientific session: A National E-Infrastructure for Aging Research to Improve Public Health

Abstract Global life expectancy gains over the last half-century are remarkable. Yet the resulting demographic shift towards an older population poses substantial public health challenges, particularly in healthcare. To address these challenges, a profound and scientifically-based understanding of older adults’ health and care requirements is needed. Recognizing the need for a better understanding of the aging process and public health challenges, the National E-infrastructure for Aging Research (NEAR) was founded in 2018. NEAR seeks to promote and support aging research by facilitating longitudinal population-based data usage from 15 well-known Swedish cohort studies on aging and health. It is based on a collaboration between eight Swedish universities and includes 15 databases with individual assessments. NEAR comprises a broad range of biomedical, clinical, social, and psychological health data from more than 90,000 adults who are 50+ years old. These individuals have been followed between 12 and 52 years. The objective of this workshop is to give an overview of the NEAR infrastructure, present results from three ongoing NEAR projects, and their implications for public health: 1) Temporal trends in dementia incidence in Sweden; 2) Personality and biomarkers of neurodegeneration and Alzheimer’s disease in Swedish older adults, and 3) Characterizing risk profiles and transitions across living and care settings in Sweden. Infrastructures such as NEAR offer high-quality epidemiological data for achieving broad, interdisciplinary research goals that single databases often cannot provide. Moreover, the value added to these kinds of data includes enhanced sample sizes, variations, representativeness, and generalizability. In turn, this can address an aging society’s public and clinical health demands. Eventually, this could lead to sustainable intervention strategies for improving older persons’ health in the coming decades. Key messages • Discover new avenues in public health aging research: Gain insights into cutting-edge aging research opportunities in Sweden, exploring key NEAR projects. • Recognize the value of national infrastructures using high-quality epidemiological data in fostering collaborative and nationally representative public health research.

Monitoring the digital healthcare transition in Denmark: Challenges, achievements and future

Abstract Denmark is often mentioned as one of the countries that have introduced digital solutions early and extensively within the health care sector, including the launch of health portal sundhed.dk in 2003, the introduction of the e-record system ‘e-Journalen’ in 2007, and the establishment of a national infrastructure for telemedicine in 2012. Denmark is well advanced in digital health measurement, providing opportunities for researching the digital transition and its effects for healthcare organizations and Danish citizens. Most digital health data is collected through national population-based databases and registries. Additionally, annual surveys of health professionals and biennial surveys of citizens’ use of health IT are conducted. Recent data show that all general practitioners use electronic health records, mainly for receiving laboratory test results from hospitals, ordering prescriptions at pharmacies, exchanging records, and sending referrals to hospitals. This workshop provides an overview of developments in Denmark and a discussion of challenges, achievements, and prospects. Particular attention will be paid to the monitoring of digitalization progress and effects, and the use of digital solutions in primary and secondary care. Issues about implementation and evaluation of digital infrastructure will be discussed with examples from Danish health care. A key question is whether digital solutions can fulfill their promise of supporting integrated and home based health care in an era of changing demographics.

Kepastian Hukum bagi Foregin Direct Investment (FDI) dalam Skema Kerjasama Pemerintah dengan Badan Usaha (KPBU) di Ibu Kota Nusantara (IKN)

The arrival of foreign investors in the development of the IKN must be followed by legal protection for foreign investors because it is very important to attract and retain investors who come. Legal protection provided to foreign investors consists of guarantees of legal certainty, guarantees of protection for foreign investors against non-commercial risks, guarantees of equal treatment for all investors and guarantees against nationalization and other takeover actions. The purpose of this study is to provide legal certainty for Foreign Direct Investment (FDI) in the government cooperation scheme with KPBU in the IKN. In conducting this research, the author uses a normative legal research method and is descriptive analytical in nature. The legal sources that form the basis of the KPBU scheme are regulated in Law No. 25 of 2007 concerning Investment, and Presidential Regulation No. 38 of 2015 which regulates KPBU in the provision of infrastructure. In addition, the government also provides support in the form of guarantees for investors, which aims to minimize the risks faced by the Implementing Business Entity (BUP) in infrastructure projects in the IKN. Projects such as Palapa Ring and SPAM Umbulan are real examples of the success of the KPBU scheme in the context of national infrastructure.

Machine learning-based assessment of regional-scale variation of landslide susceptibility in central Vietnam.

Recurrent landslide events triggered by typhoons and tropical storms over Vietnam pose a longstanding threat to the nation's population and infrastructure. Changes in hydroclimatic conditions, especially the growing intensity and frequency of storms, have elevated landslide susceptibility in many parts of the country. This research examines the spatio-temporal variations in landslide susceptibility across central Vietnam over several years, using multi-temporal landslide inventories from Typhoon Ketsana (2009), Tropical Storm Podul (2013), and Typhoon Molave (2020). Additionally, the research explores the impact of individual landslide causative factors on the probabilistic occurrences of landslides. The post-event landslide susceptibility models of these three climate extreme events were developed using nine causative factors and a Random Forest machine learning algorithm. The results indicate a notable areal expansion of high to very high landslide susceptibility in the northern and eastern regions and a moderate reduction in the central and southern areas during the post-Molave period compared to the post-Ketsana period. These changes may be early indicators of increasing landslide susceptibility in response to changing hydro-climatic conditions. The research found that annual average rainfall and topographic elevation are the two most important variables influencing landslide prediction, showing a nonlinear relationship with landslide probability. The landslide susceptibility models achieved high Area Under the Receiver Operating Characteristic Curve (AUC) (>95%), accuracy (>89%), and sensitivity (>90%) scores, signifying the robustness of the models. Additionally, the uncertainty of the models was quantified and spatially mapped. This multi-temporal analysis of landslide susceptibility is crucial for understanding the regional susceptibility trends and identifying areas with increasing, decreasing, and consistently high susceptibility to landslides. These insights are invaluable for prioritizing mitigation and risk reduction strategies in landslide-prone regions and guiding appropriate land use planning.

Performance of the polyurethane foam injection technique for road maintenance applications

Road infrastructure plays an important role in strengthening transportation and driving the economic advancement of countries. However, the increasing traffic volume has accelerated road deterioration, particularly at critical points like bridge-road junctions. Traditional repair methods involving demolition and reconstruction lead to extended closures and high costs. This study explores the polyurethane (PU) foam injection technique as an alternative solution, which can reduce both repair time and costs. The research evaluates the application of PU foam in various road projects across Thailand, highlighting its ability to repair pavement surfaces and structures, even in severely damaged areas. Despite its advantages, the use of PU foam faces challenges due to a lack of standardized quality control. This paper proposes a set of working guidelines for PU foam injection, aimed at key stakeholders such as the Department of Highways, the Department of Rural Roads, and the Department of Local Administration. The findings underline the importance of establishing standardized methods to ensure the long-term effectiveness of PU foam in road maintenance. Future research should focus on refining these guidelines for diverse road conditions to support the sustainable development of national transportation infrastructure.
