Background: Clinicians are currently challenged to support older adults to maintain a certain level of Functional Independence (FI). FI is defined as "functioning physically safely and independent from another person, within one's own context". A Core Outcome Set was developed to measure FI. The purpose of this study was to assess discriminative validity of the Core Outcome Set FI (COSFI) in a population of Dutch older adults (≥ 65 years) with different levels of FI. Secondary objective was to assess to what extent the underlying domains 'coping', 'empowerment' and 'health literacy' contribute to the COSFI in addition to the domain 'physical capacity'. Methods: A population of 200 community-dwelling older adults and older adults living in residential care facilities were evaluated by the COSFI. The COSFI contains measurements on the four domains of FI: physical capacity, coping, empowerment and health literacy. In line with the COSMIN Study Design checklist for Patient-reported outcome measurement instruments, predefined hypotheses regarding prediction accuracy and differences between three subgroups of FI were tested. Testing included ordinal logistic regression analysis, with main outcome prediction accuracy of the COSFI on a proxy indicator for FI. Results: Overall, the prediction accuracy of the COSFI was 68%. For older adults living at home and depending on help in (i)ADL, prediction accuracy was 58%. 60% of the preset hypotheses were confirmed. Only physical capacity measured with Short Physical Performance Battery was significantly associated with group membership. Adding health literacy with coping or empowerment to a model with physical capacity improved the model significantly (p < 0.01). Conclusions: The current composition of the COSFI, did not yet meet the COSMIN criteria for discriminative validity. However, with some adjustments, the COSFI potentially becomes a valuable instrument for clinical practice. Context-related factors, like the presence of a spouse, also may be a determining factor in this population. It is recommended to include context-related factors in further research on determining FI in subgroups of older people.

Thirty to sixty per cent of older patients experience functional decline after hospitalisation, associated with an increase in dependence, readmission, nursing home placement and mortality. First step in prevention is the identification of patients at risk. The objective of this study is to develop and validate a prediction model to assess the risk of functional decline in older hospitalised patients.

The research proposal aims to improve the design and verification process for coastal protection works. With global sea levels rising, the Netherlands, in particular, faces the challenge of protecting its coastline from potential flooding. Four strategies for coastal protection are recognized: protection-closed (dikes, dams, dunes), protection-open (storm surge barriers), advancing the coastline (beach suppletion, reclamation), and accommodation through "living with water" concepts. The construction process of coastal protection works involves collaboration between the client and contractors. Different roles, such as project management, project control, stakeholder management, technical management, and contract management, work together to ensure the project's success. The design and verification process is crucial in coastal protection projects. The contract may include functional requirements or detailed design specifications. Design drawings with tolerances are created before construction begins. During construction and final verification, the design is measured using survey data. The accuracy of the measurement techniques used can impact the construction process and may lead to contractual issues if not properly planned. The problem addressed in the research proposal is the lack of a comprehensive and consistent process for defining and verifying design specifications in coastal protection projects. Existing documents focus on specific aspects of the process but do not provide a holistic approach. The research aims to improve the definition and verification of design specifications through a systematic review of contractual parameters and survey methods. It seeks to reduce potential claims, improve safety, enhance the competitiveness of maritime construction companies, and decrease time spent on contractual discussions. The research will have several outcomes, including a body of knowledge describing existing and best practices, a set of best practices and recommendations for verifying specific design parameters, and supporting documents such as algorithms for verification.
The transition to a circular economy requires innovative digital solutions to extend the lifespan of electrical and electronic appliances (EEA) and reduce the volume of waste generated by this product stream. Digital Product Passports (DPPs) make product and usage information accessible to supply chain partners and serve as a crucial tool for optimising circular strategies. DPP data on performed maintenance, upgrades, (sensor) data on EEA usage, diagnostics and repairs support supply chain actors throughout the product lifecycle in carrying out their circular responsibilities. This project focuses on the application of DPPs in the "Middle-of-Life" phase of EEA products, specifically dishwashers and coffee machines. The central research question is: How can the EEA supply chain design and actively manage a DPP in a way that creates value for all stakeholders in the Middle-of-Life phase and contributes to product life extension and circularity? The applied methodology is based on Design Science Research (DSR) and Co-design, in which manufacturers, repair services, collection partners and DPP solution providers collaborate on a practice-oriented implementation. In co-design sessions, the requirements and functionalities of DPPs are defined based on identified circular roles and related information needs. These are then translated into a DPP "Proof of Concept", which is tested by partners across the electronics value chain. The intended outcome is an implemented and validated DPP concept that unlocks product data, optimises circular processes, and strengthens collaboration within the supply chain. This project contributes to strategic policy agendas on digitalisation and circularity and offers a blueprint for the broader application of DPPs in the EEA sector. The project partners – ATAG Benelux, E-Care, Beekman B.V., Holland Circulair, Eviden, Saxion University of Applied Sciences, and HU University of Applied Sciences Utrecht – combine their expertise to develop a future-proof, scalable and practice-based DPP solution.
Public safety is under enormous pressure. Demonstrations regularly result in riots and VIPs are often threatened even at their homes ! Criminal graffiti-gangs are threatening security professionals and costing the Dutch railways (NS), causing a loss of 10 M€ yearly. The safety incidents often escalate quickly, therefore, they require a very quick and correct scaling up of the security professionals. To do so, it is necessary for the security professionals to get very quick and accurate overview of the evolving situation using Mobile Drone intervention unit for quick response (Mobi Dick). The successfully completed project The Beast (9/11) has delivered a universal docking station with an automatic security drone. The drone takes off from a permanently installed docking station. Nest Fly emerged as a startup from this RAAK project, and it has already developed the prototype further to a first product. Based on extensive interaction with security professionals, it has been concluded that a permanently installed docking station is not suitable for all emergency cases. Therefore, a mobile, car-roof top mounted, docking station with a ready-for-take-off drone is required for the more severe and quickly escalating incidents. These situations require a drone taking off from the car-roof top mounted docking station while the vehicles continue to drive towards the incident. In this RAAK KIEM, a feasibility study will be executed by developing a car-roof top docking station. The concept will functionally be designed within the project (task 1). The two required subsystems car roof docking station (task 2) and dynamic take-off & landing (task 3) will technically be developed and integrated (task 4). The outcome of the experiments in this task will show the feasibly of the idea. Task 5 will ensure the results are disseminated in new cooperation’s, publications, and educational products.
