Smart FOX - Enabling Citizen-Based Donation of EHR-Standardised Data for Clinical Research in Austria.

Access to healthcare data for secondary use in clinical research is often restricted due to privacy concerns or business interests, hindering comprehensive analysis across patient pathways. The Smart FOX project seeks to address this challenge by developing concepts, methods, and tools to facilitate citizen/patient-driven donations of health data for clinical research. Leveraging the groundwork, laid by the national Electronic Health Record implementation in Austria (called ELGA), Smart FOX aims to harness structured datasets from ELGA for research purposes through an opt-in approach. With funding secured from the Austrian Research Promotion Agency, the project embarks on innovative solutions encompassing governance frameworks, community engagement, and technical infrastructure. The Smart FOX consortium, comprising key stakeholders across various healthcare-associated domains, will evaluate these efforts through demonstrators focusing on clinical registries, patient-generated data, and recruitment services. The project targets to accompany the development of future data donation infrastructure while ultimately advancing clinical research efficiency and bolstering Austria's preparedness for the European Health Data Space. This paper presents the first systematic evaluation of the technical concept and proposal for the federated system architecture of the Austrian Health Data Donation Space, which is the socio-technical goal of Smart FOX.

Construction Technology and Service Performance of Waterproof Curtain for Foundation Pit in Large-Particle Pebble Gravel Layer of Yangtze River Floodplain

A foundation pit is constructed in the floodplain of Yangtze River, and a deep and thick layer of large-particle pebble gravel exists below the base slab, thus forming a connected supply channel with the adjacent Yangtze River. The large water volume, high water pressure, and strong permeability of this layer bring great risks to the foundation pit construction. In view of the fact that conventional waterproof curtain construction technologies such as the deep mixing column and high-pressure jet grouting column cannot meet the engineering requirements under these kinds of geological and environmental conditions, a new waterproof curtain construction technology that combines the trenching technology of the diaphragm wall with the TRD (Trench cutting Remixing Deep wall) technology is proposed, i.e., the trenching-and-replacing-style TRD technology, as well as the construction process of this technology, is presented. After the waterproof curtain is built using the proposed technology, the strength, integrity, uniformity, and service performance of the waterproof curtain wall are tested and evaluated by the comprehensive methods of coring, borehole television imaging, resistivity CT, and a group well pumping test. The results show that the proposed technology overcomes the adverse effects of underlying large-particle pebble gravel layer, and the waterproof curtain built by it effectively cuts off the hydraulic connection inside and outside the pit. The technical proposal can provide useful references for similar projects.

Driving scheme for residual image reduction in active-matrix organic light-emitting diodes display

Residual image is a frequent issue in active-matrix organic light-emitting diode (AMOLED) display, due to hysteresis effects of the internal devices. Up to now, some optimized methods have been researched mainly from process perspective. However, the approaches from driving scheme perspective and their electrical mechanism have rarely been demonstrated systematically. In this work, a technical proposal has been proposed to separate the influences of different devices including both thin film transistors (TFTs) and OLEDs furtherly. It was found that the current curve gap was nearly equal to the luminance curve gap and the main factor of residual image was shown to be the hysteresis of TFTs. An equivalent circuit of two thin film transistors and one capacitor (2T1C) was also adopted to substantiate the influences of threshold voltage (Vth) compensation for reducing residual image, and a series of experiments of tuning capacitance were carried out for corresponding compensation improvements. Moreover, other driving scheme optimizations were also studied to reduce residual image furtherly, including increasing the data input time and resetting the driving TFTs. The research opens the possibility of considering reduction of residual image from driving scheme perspective and more systemic analysis from the internal electrical mechanism in AMOLED display.

56‐1: Invited Paper: Mechanical Strength Improvement of Foldable Panel with COE

It is significant to reduce power consumption and thickness of foldable display with larger size. Color filter on Encapsulation (COE), as one of the most critical technologies, has excellent performance in terms of power consumption and thinning. COE refers to the technical proposal replacing polarizer with color filter on the surface of encapsulation(COE). However, we have encountered two problems of reduced mechanical strength in the mass production. One of the problems is panel peeling in module process, and the other one is cracking during drop test. This paper has studied the root cause of COE panel strength reduction from panel design, process and material. As a result we achieved the same mechanical strength as polarizer panel.

ОСОБЛИВОСТІ ПРОЄКТУВАННЯ МЕХАНІЗАЦІЇ КРИЛА ЛІТАКІВ ТРАНСПОРТНОЇ КАТЕГОРІЇ

The paper analyses the methods of designing wing mechanisation for transport category aircraft. The wing layout with the placement of wing mechanisation means on the leading and trailing edges of the wing is analysed. Specific requirements for wing mechanisation units are considered. The analysis takes into account the requirements of aircraft operation, which provide easy access to inspect the mechanisation units and their attachment mechanisms. The need for constant monitoring of the synchronous operation of all mechanisation sections and ensuring their smooth movement is emphasised. The design of any type of mechanisation means involves the simultaneous solution of a number of development tasks: kinematic scheme, installation and control system, support structure and the device itself. In most cases, the drive mechanisms are also developed. The design of a new aircraft is a multi-stage iterative process that includes external design, development of a technical proposal, preliminary design, detailed design, production of prototypes, ground and flight tests, which determine the actual characteristics of the aircraft and the degree of its compliance with the technical specifications. Consider the advantages created by wing mechanisation equipment. The mechanisation of the AN-140 is considered as a representative of aircraft whose wings have trailing edge mechanisation but no leading edge mechanisation. The mechanisation of the AN-74 is also considered as a representative of aircraft that use two- or three-slotted retractable flaps, winglets or nose shields of large curvature over the entire wing span. The design technologies in integrated computer information systems are characterised, which allow to build a single process of computer modelling and engineering analysis and to conduct multivariate studies to select optimal design solutions in a sufficiently short time. A block diagram of the process of detailed design of flaps is proposed.

Blinding reduces institutional prestige bias during initial review of applications for a young investigator award.

Organizations that fund research are keen to ensure that their grant selection processes are fair and equitable for all applicants. In 2020, the Arnold and Mabel Beckman Foundation introduced blinding to the first stage of the process used to review applications for Beckman Young Investigator (BYI) awards: applicants were instructed to blind the technical proposal in their initial Letter of Intent by omitting their name, gender, gender-identifying pronouns, and institutional information. Here we examine the impact of this change by comparing the data on gender and institutional prestige of the applicants in the first four years of the new policy (BYI award years 2021-2024) with data on the last four years of the old policy (2017-2020). We find that under the new policy, the distribution of applicants invited to submit a full application shifted from those affiliated with institutions regarded as more prestigious to those outside of this group, and that this trend continued through to the final program awards. We did not find evidence of a shift in the distribution of applicants with respect to gender.

Progressive pollen calendar to detect long-term changes in the biological air quality of cities in the Madrid Region, Spain

Rhinoconjunctivitis and allergic asthma are among the most frequent diseases in the world, and pollen is their main cause. The incidence of respiratory allergic diseases is expected to grow in the coming years as a consequence of ambient pollution, changes in land use and land cover in cities, and climate change. In this context of global change, the environmental information provided by monitoring and warning networks must be as updated as possible in order to be useful to the end users in the cities. The Madrid Autonomous Region (central Spain) has suffered a noticeable change in its land-use configuration in recent decades and a significant upward temperature trend throughout the entire area. We found that the aerobiological stations in the Madrid Region Palynological Network, covering the most populated cities of this region in central Spain, registered a marked shift towards a greater airborne pollen load of the most abundant tree pollen taxa (Cupressaceae, Platanus and Quercus, but also Pinaceae, Olea and others). These temporal changes are very evident in the pollen calendar for two periods, 1994–2004 (past) and 2012–2022 (present), pointing to changes in the phenology and intensity of the airborne pollen dynamic in cities in the Madrid Region. Based on these findings, we present a technical proposal to the Madrid Region Palynological Network to generate pollen calendars for each city using the reference period of the last ten years, and to update this information every three years. Finally, we propose the latest pollen calendar for all the aerobiological stations in the Madrid Region Palynological Network for the last ten years (2013–2022), which is considered the reference aerobiological information at present for one of the most populated metropolitan areas in Europe.

A Systematic Approach to the Search for New Technical Solutions for Electronic Equipment at the Initial Stages of Design

A systematic approach is described to search for new technical solutions for radio-electronic units at the stage of technical proposal. It is based on the transformation of the electrical circuit of the device being developed into an object-oriented model reflecting its physical principle of operation. Operators for processing working signals are proposed, which allow choosing alternative technical implementations of fragments of electrical circuits for obtaining new technical solutions. At the same time, parameters are introduced to limit the applicability of operators as part of signal processing facilities to ensure the operability of the radio-electronic device. The proposed approach can be used in the development of new and modernization of existing computer-aided design systems of electronic equipment.

Survey on the LAN MCS Gap Analysis (LMGA)

Abstract This survey paper can fill a literature gap in LAN/Ethernet modulation and coding scheme. During the past several decades, even though there were many technical papers on MCS technologies in the IEEE 802.3 Ethernet standard development process, those papers are only technical discussions for specific technical proposals and analysis for special application scenarios. There is no paper providing a historical overview of IEEE LAN/Ethernet MCS system. This paper is proposing to establish a research project to cover MCS deficiency gap analysis in the application field of LAN (Ethernet) communications systems. Research on LMGA is a mission to collect information on LAN MCS technologies, conduct analysis on the gaps between MCS practices and market needs so that in the future MCS Innovation development stages including technical requirements and proposal selections, LAN MCS gaps can be filled and to facilitate quick application and adoption into the field for new MCS technologies.

Sheath-Based Combined Foam Sclerotherapy to Promote Management of Extensive Insufficiency of the Great Saphenous Vein in Venous Ulcers.

Background: Foam sclerotherapy is considered an acceptable method to treat great saphenous vein (GSV) insufficiency, promoting occlusion of its trunk and eradicating reflux. Various modalities and techniques have been described, varying form foam infusion through multiple short cannulae along the GSV to catheter-directed techniques in order to facilitate complete proximal GSV occlusion and improve technical and clinical success. Purpose: To present a modification of the sclerotherapy tehcnique where the presence of venous ulcers poses an extra challenge to the treatment of GSV treatment. Technique: We describe a technical proposal of single foam perfusion through a 11cm 5F sheath placed at the knee level combined with simultaneous retrograde infusion below the knee. Perivenous tumescent segmental infiltration with cold normal saline at 4°C is applied initially to reduce the diameter in those GSV >6-7mm. Conclusions: This combination avoids multiple vein cannulation in the GSV along the thigh as well as the need for antegrade infusion when GSV cannulation at the lower tibia is prohibited by a large ulcer area.

Development of a Decision-Making Model to Support the Strategic Environmental Assessment for the Revision of the Municipal Plan of Turin (Italy)

This article presents a decision-making model for assessing the sustainability of urban plans and programmes to envision long-term transformation scenarios through the development of consistency matrices. The tool was tested in a real case study, which is the Strategic Environmental Assessment for the Revision of the General Municipal Plan of the City of Turin (Italy). The changes that have taken place in recent years have highlighted the need for more flexible, dynamic, and streamlined tools that can help the revision of plans and programmes, which are capable also of considering the citizen’s needs. The decision-making model provided in this paper was structured into five phases: normative framing of the environmental assessment procedures; spatial analysis by structures; consistency analysis of conformity between the objectives of the technical proposal of the preliminary draft and the superordinate and coordinated planning; monitoring of the technical proposal through the employment of key indicators; and the definition of guidelines for the General Regulatory Plan of the City of Turin. The tool presented in this work can support planners, municipal technicians, and general public administrations, both in the planning and assessment processes to design and implement sustainable policy recommendations capable of tackling the increasing complexity of urban transformations.

Design and Fabrication of Bistratal Functional Anionic Polyurethane Membrane on the Surface of Cashmere Fiber Based on Foaming Micro-Coating and the Studies of its Structure–Activity Relationships

This research aims to reinforce the hand-feeling and washing fastness of anti-pilling and antistatic cashmere textiles based on a traditional “addition” technique. The technical proposal that effectively controls the distribution of polymer on cashmere textiles, based on foaming micro-coating technology, is studied and compared to prevent the superabundant polymer being fixed in the gaps between yarns/fibers and to ensure the graphene is semi-embedded in the membrane of “Table coating.” A couple of flexible hydrophilic anionic polyurethanes are used in micro-coating processing of cashmere purposefully. The effects of different coating technique on pilling, static, anti-ultraviolet, and washing resistance of coated cashmere textiles are studied. The results show that the semi-embedded graphene in the table coating membrane is meaningful to the static resistance. The pilling resistance of cashmere textile covered by polymer membranes is enhanced from grade 1–2 to grade 4–5 when the weight gain rate of “Bottom coating” polyurethane reaches 1.5% (o.w.f.), and its static voltage half-life decreases from 170 s to less than 2 s. In addition, the ultraviolet protection factor (UPF) value of coated cashmere is doubled, and anti-pilling and anti-static effects can withstand five washings.

Evaluation of a new approach for swine wastewater valorisation and treatment: A combined system of ammonium recovery and aerated constructed wetland

Nitrate Vulnerable Zones (NVZs) are faced with a surplus of animal manure due to intensive livestock production, and the high use of mineral nitrogen (N) fertilisers in crop production. Recovery of N from animal manure to replace synthetic mineral fertilisers is considered a key strategy to close the N loop for more sustainable agriculture and to meet strict legal frameworks. In this study, N recovery from swine wastewater by an ammonia (NH3) stripping process followed by purification via an aerated constructed wetland (ACW) was proposed as an alternative approach to conventional systems based on biological nitrification-denitrification (NDN) treatment. The performance of the NH3 stripping pilot as well as the ACW was monitored in 2019–2020 over three periods, to evaluate the quality of recovered ammonium nitrate (AN) solution and the effluent of the ACW. Results showed that the NH3 stripping unit recovered 21% of total-N (32% of mineral-N) in the form of AN solution. This could be used as a mineral fertiliser according to the criteria of the European Fertilising Products Regulation 2019/1009 and the technical proposal of manure-derived RENURE (REcovered Nitrogen from manURE) products by the European Joint Research Centre. As a RENURE product, AN solution would reach an end-of-manure status and could be used as a synthetic N fertiliser replacement. The tested ACW achieved a high removal efficiency with respect to suspended solids (96%), biological oxygen demand (96%), chemical oxygen demand (90%), total-N (80%), and total phosphorus (97%). The quality of ACW effluent was comparable to that of NDN treatment. Though the overall cost of the proposed pilot-scale process consisting of NH3 stripping (5.1 € t−1) and ACW (12 € t−1) was calculated slightly higher than conventional NDN treatment (16 € t−1), it is foreseen to outcompete at a higher loading rate (over 45 m3 ha−1 d−1). Furthermore, post-purification will be needed for the ACW effluent to meet the requirements for discharge to surface water.

The ISM Method to Analyze the Relationship between Blockchain Adoption Criteria in University: An Indonesian Case

Referring to the widespread problem of diploma forgery in Indonesian educational institutions as the impetus for UNTIRTA’s latest vision as an “Integrated, Smart, and Green University,” UNTIRTA intends to use blockchain technology to prevent diploma forgery and overcome issues related to existing platforms at UNTIRTA, such as frequent connection interruptions when accessed by a large number of users simultaneously. Before using blockchain technology, UNTIRTA must evaluate several readiness issues. This study presented the interpretative structural modeling (ISM) method to assess the primary preparedness elements for adopting blockchain technology in universities and sought to provide pertinent strategy ideas for UNTIRTA’s blockchain technology application. The results reveal sixteen major parameters that influence the adoption readiness of blockchain technology at UNTIRTA. The primary variables impacting the adoption and deployment of blockchain technology at UNTIRTA are management and employee support and a grasp of the technology. To realize UNTIRTA’s mission as an “Integrated, Smart, and Green University”, the proposed method entails determining an initial agreement in which all stakeholders have a shared understanding and commitment to Blockchain technology implementation at UNTIRTA. The objective of the tactical proposal is to establish each unit’s mission in the blockchain implementation program. The objective of the technical proposal is to construct a planning document that will serve as a coordination tool between the chairman and members, as well as all parties interested in the adoption of Blockchain technology at UNTIRTA.

Алгоритмы, методы и подходы к обезличиванию и обогащению данных, в том числе персональных

This article presents the results of a study of algorithms, methods and approaches to depersonalization and enrichment of data, including personal data. Among the types of data enrichment, demographic, geographic and behavioral data enrichments were considered, as well as statistical, semantic and pragmatic data enrichment algorithms were studied. In addition to data enrichment, categories of ontology enrichment were considered, namely expressive ontologies, lightweight ontologies such as taxonomies, and a category that includes works that use reasoning to partially replace traditional methods of knowledge extraction. Ontology enrichment is a broad area of research that can be divided into three categories of work devoted to extracting semantic knowledge from heterogeneous data. As a result of the analysis, it was found that data enrichment processes optimize sales, as well as reduce business costs, by saving finances through information management. The advantages and disadvantages of the considered approaches and methods of data enrichment and ontologies were presented. The main benefit of fortification is the increased value and accuracy of information that helps companies make important business decisions. The main disadvantage is the risk of growing redundant data, which can lead to incorrect analytics and, accordingly, to wrong business decisions, which in turn harms the business. The significance of the analysis is also presented – on the basis of the studies carried out, it is planned to form a technical proposal for creating the basic infrastructure of the project of the NTI Central Committee "Trusted Information Exchange Environment" for further research on the topic of data enrichment and depersonalization.
