Protective clothing is designed to protect humans against risks like fire, chemicals or blunt impact. Although protect¡ve clothing diminishes the effects of external risks, it may hinder people in functioning and it may also introduce new (internal) risks. Manufacturers are often not aware of the seriousness of those risks. Prof. Daanen, human movement scientist, postulates that knowledge on human physiology must be part of protective clothing design. After a career in protective clothing research that started about 25 years ago at TNO (NL) he is entitled to say things like that.

Humans can easily generate more than 1000 W of heat during heavy exercise. This heat has to be transferred to the environment to stay in thermal equilibrium. During exercise in extreme cold, heat loss may exceed heat production, and clothing is necessary to prevent hypothermia. It will be shown how ISO standard 11079 can be used to assess the necessary clothing insulation. In the heat, clothing is necessary in sports for identification, ethical reasons, and to protect our body against impact. Guidelines and examples will be supplied on factors to consider to prevent discomfort and optimize performance during exercise in the heat.

Background The global nursing shortages exacerbated by the COVID-19 pandemic necessitated a drastic reorganization in nursing practices. Work routines, the composition of teams and subsequently mundane nursing practices were all altered to sustain the accessibility and quality of care. These dramatic changes demanded a reshaping of the nurses’ work environment. The aim of this study was to explore how nurses reshaped their work environment in the early stages of the COVID-19 pandemic. Methods A descriptive study comprising 26 semi-structured interviews conducted in a large Dutch teaching hospital between June and September 2020. Participants were nurses (including intensive care unit nurses), outpatient clinic assistants, nurse managers, and management (including one member of the Nurse Practice Council). The interviews were analysed with open, axial, and selective coding. Results We identified five themes: 1) the Nursing Staff Deployment Plan created new micro-teams with complementary roles to meet the care needs of COVID-19 infected patients; 2) nurse-led adaptations effectively managed the increased workload, thereby ensuring the quality of care; 3) continuous professional development ensured adequate competence levels for all roles; 4) interprofessional collaboration resulted in experienced solidarity, a positive atmosphere, and increased autonomy for nurses; and, 5) supportive managers reduced nurses’ stress and improved work conditions. Conclusions This study showed that nurses positively reshaped their work environment during the COVID-19 pandemic. They contributed to innovative solutions in an environment of equal interprofessional collaboration, which led to greater respect for their knowledge and competencies, enhanced their autonomy and improved management support.

Objective: There are widespread shortages of personal protective equipment as a result of the COVID-19 pandemic. Reprocessing filtering facepiece particle (FFP)-type respirators may provide an alternative solution in keeping healthcare professionals safe. Design: Prospective, bench-to-bedside. Setting: A primary care-based study using FFP-2 respirators without exhalation valve (3M Aura 1862+ (20 samples), Maco Pharma ZZM002 (14 samples)), FFP-2 respirators with valve (3M Aura 9322+ (six samples) and San Huei 2920V (16 samples)) and valved FFP type 3 respirators (Safe Worker 1016 (10 samples)). Interventions: All masks were reprocessed using a medical autoclave (17 min at 121°C with 34 min total cycle time) and subsequently tested up to three times whether these respirators retained their integrity (seal check and pressure drop) and ability to filter small particles (0.3–5.0 µm) in the laboratory using a particle penetration test. Results: We tested 33 respirators and 66 samples for filter capacity. All FFP-2 respirators retained their shape, whereas half of the decontaminated FFP-3 respirators showed deformities and failed the seal check. The filtering capacity of the 3M Aura 1862 was best retained after one, two and three decontamination cycles (0.3 µm: 99.3%±0.3% (new) vs 97.0±1.3, 94.2±1.3% or 94.4±1.6; p<0.001). Of the other FFP-2 respirators, the San Huei 2920 V had 95.5%±0.7% at baseline vs 92.3%±1.7% vs 90.0±0.7 after one-time and two-time decontaminations, respectively (p<0.001). The tested FFP-3 respirator (Safe Worker 1016) had a filter capacity of 96.5%±0.7% at baseline and 60.3%±5.7% after one-time decontamination (p<0.001). Breathing and pressure resistance tests indicated no relevant pressure changes between respirators that were used once, twice or thrice. Conclusion: This small single-centre study shows that selected FFP-2 respirators may be reprocessed for use in primary care, as the tested masks retain their shape, ability to retain particles and breathing comfort after decontamination using a medical autoclave.

Aim and method: To examine in obese people the potential effectiveness of a six-week, two times weekly aquajogging program on body composition, fitness, health-related quality of life and exercise beliefs. Fifteen otherwise healthy obese persons participated in a pilot study. Results: Total fat mass and waist circumference decreased 1.4 kg (p = .03) and 3.1 cm (p = .005) respectively. The distance in the Six-Minute Walk Test increased 41 meters (p = .001). Three scales of the Impact of Weight on Quality of Life-Lite questionnaire improved: physical function (p = .008), self-esteem (p = .004), and public distress (p = .04). Increased perceived exercise benefits (p = .02) and decreased embarrassment (p = .03) were observed. Conclusions: Aquajogging was associated with reduced body fat and waist circumference, and improved aerobic fitness and quality of life. These findings suggest the usefulness of conducting a randomized controlled trial with long-term outcome assessments.

This report was produced within the framework of the RAAK PRP project ‘Veiligheid op de werkvloer’. Personal protective equipment (PPE) is used on a daily basis by millions of people all over the EU, voluntarily or as a result of EU legislation. In this report we deal specifically with the textile/garment aspects of PPE. In this context we must consider the fact that PPE encompasses a huge area with hundreds of different applications of materials and systems tuned to specific needs;from a materials point of view it represents a complex area due to the large diversity of labour conditions. Textiles and clothing represent an area where PPE is an important area of attention. On a global scale it is an area of much research. Safety and comfort are becoming more and more important and these aspects must be in balance. Uncomfortable systems will not be used and put safe working at risk. Thus there is a continuous need for technological innovation to improve the effectiveness of PPE systems. Specialization and specific combinations aimed at use under well-defined conditions contributes to finding a good balance between comfort and safety. The design of products, taking into account the individual needs represent an area of intensive research: Safety directed ‘fashion design’.The ultimate goal is the development of proactive systems by which workers (but capital goods as well) are optimally protected. There is also a lot of attention for maintenance and cleaning since protective functions may deteriorate as a result of cleaning processes. Another important point is standardization because producers need directions for product development and supply of goods. In our overview we make a distinction between static and dynamic systems. Static systems provide passive protection, simply by being a part of an equipment that separates the worker from the danger zone. Dynamic systems are more ‘intelligent’ because these can react to stimuli and subsequently can take action. These dynamic systems use sensors, communication technology and actuators. From this research the following may be concluded: 1. Safety is obtained by choice of materials for a textile construction, including the use of coatings with special properties, application of specific additives and he use of special designed fibre shapes. 2. The architecture and ultimate construction and the combinations with other materials result in products that respond adequately. This is of great importance because of the balance comfort – safety. But a lot can be improved in this respect. 3. Insight in human behaviour, ambient intelligence and systems technology will lead to new routes for product development and a more active approach and higher levels of safety on the work floor. Consequently there is a lot of research going on that is aimed at improved materials and systems. Also due to the enormous research area of smart textiles a lot of development is aimed at the integration of new technology for application in PPE. This results in complex products that enhance both passive and active safety. Especially the commissioners, government and industry, must pay a lot of attention to specifying the required properties that a product should meet under the specific conditions. This has a cost aspect as well because production volumes are usually not that large if for small groups of products specific demands are defined. We expect that through the technology that is being developed in the scope of mass customization production technologies will be developed that allows production at acceptable cost, but still aimed at products that have specific properties for unique application areas. Purchasing is now being practiced through large procurements. We must than consider the fact that specification takes place on the basis of functionality. In that case we should move away from the current cost focus but the attention should shift towards the life cycle

This text is structured as follows. Section 1 concerns the background to this public lecture: the fact that social participation is becoming increasingly important in our society. This is evident, for example, from the way we are evolving from a protective welfare state into an activational, participative society. This development has consequences for the social sector and therefore also for the professionals who work in it. Social work professionals are not necessarily expected to identify or solve participation problems; they are seen as intermediaries who enable citizens to take responsibility themselves. Social work professionals are therefore expected to provide the individual applicant with less direct support and to focus more on strengthening the social networks of people and the social contexts in which they find themselves. Section 2 connects sections 1 and 3, but may also be read independently. It is about the fact that social work professionals are not yet in the habit of providing systematic insight into the results of their actions, while policy makers, for example, are increasingly looking to them precisely for this. First of all, I set out the reasons why it is so important to make the products of their interventions more visible, not only to policy makers, but also to social work professionals themselves and to the customers/citizens who depend on them. Secondly, I set out how the results of social interventions can be made more visible than they are at present; and what research can contribute. In this, I advocate a change in thinking: from thinking in terms of the evidence to thinking in terms of the evident. This argument forms the basis of the type of research that is being taken up from within the research group. In section 3, I describe a number of research projects that will be conducted during my tenure. I also set out the main proposition of this address, which states that social work professionals should do more with the knowledge that peoples behaviour is determined to a significant degree by contexts. In particular, social contexts could play a bigger role in promoting citizen participation. At present, social work professionals normally intervene directly in peoples behaviour, such as with therapies for combating problem behaviour. Interventions in a broader, social, context are rare. Why is this? And couldnt citizen participation be more effectively promoted by these means than through direct behavioural interventions? I put forward four propositions in this regard, and explain each of them in reference to one of the current research projects within the research group. With this, in combination with the general outlines of the research presented in section 2, I hope to provide a clear and inspiring overview of the research that will be carried out within the research group in the coming years. Finally, in section 4, I will discuss the significance of the research group to the faculty of Society and Law at Hogeschool Utrecht University of Applied Sciences, and to parties outside of Hogeschool Utrecht University of Applied Sciences.

Zorgcapaciteit kan een belangrijke schakel zijn tussen multi-probleem omstandigheden en ongunstige ontwikkeling van kinderen. Deze studie heeft als doel om de zorgcapaciteit en de correlaties daartussen te onderzoeken in zeer kwetsbare multiprobleemgezinnen in Rotterdam, Nederland. Zorgcapaciteit (algemeen, emotioneel en instrumenteel) werd prospectief beoordeeld bij 83 zeer kwetsbare vrouwen met behulp van video-observaties van dagelijkse zorgtaken, zes weken postpartum. Ondersteunende gegevens werden verzameld op drie tijdstippen: bij inclusie, zes weken na inclusie en zes weken postpartum, en deze omvatten psychologische symptomen, zelfredzaamheid, problematische levensdomeinen, thuisomgeving, inkomen, depressie, angst en stress. Zwangerschaps- en bevallingsgerelateerde informatie werd verzameld bij verloskundigen. De scores voor zorgverlening door de moeder waren gemiddeld van onvoldoende kwaliteit. Moeders die in een onveilige thuisomgeving leefden (B = 0,62) en moeders met meer problematische levensdomeinen (≤3 domeinen, B = 0,32) vertoonden significant hogere instrumentele zorgcapaciteiten. Andere variabelen waren niet gerelateerd aan zorgcapaciteit. De zorgcapaciteit in deze zeer kwetsbare populatie was van onvoldoende kwaliteit. In de meeste gevallen was er echter geen significant verband tussen zorgzaamheid en de variabelen die gerelateerd zijn aan kwetsbaarheid. Dit betekent dat een mogelijk verband tussen kwetsbaarheid en zorgcapaciteit kan worden veroorzaakt door de interactie tussen verschillende problemen, in plaats van door het type of de omvang van de zorg.

Brain & Technology is about the relationship between mind and technology, so about brain and lifelong learning, and therefore about the extended mind. More generally, humanity uses technology to outsource brain processes (mind) to smart devices, just as we partially outsource our digestion to cooking and skin protection to clothing. So the boundary between body and environment is by no means fixed, partly thanks to technology. A kind of weird way to say it, you could say that Brain & Technology is about border traffic, and about border possibilities and problems.
