Het gebruik van eenheden zal in de toekomst in belangrijke mate worden beïnvloed door de toepassing van het SI (het Internationale Stelsel van Eenheden). Op 1 JanuarI 1978 werd een gewijzigd artikel van de ijkwet van kracht dat het gebruik verplicht stelt van uitsluitend door de wet erkende eenheden - en dat zijn overwegend de eenheden van het SI - 'in de uitoefening van een beroep of bedrijf bij het vragen, het aanbieden of het leveren van goederen of diensten'.

Deze publicatie geeft gerichte theoretische en praktische informatie ten behoeve van respectievelijk de gebruikers van de diverse machines en gereedschappen welke bij het omvormproces (dieptrekken, kraagtrekken, strekken, alsmede buigen en scheiden) worden gebruikt, geïnteresseerden in de betreffende processen, technische cursussen en opleidingen. De inhoud van deze publicatie behandelt de belangrijkste machines en gereedschappen, alsmede aanvullende informatie welke bij het vormgeven van dunne plaat van belang zijn. In de voorlichtingspublicaties VM 110 "Dieptrekken", VM 113 "Buigen" alsmede VM 114 "Scheiden" vindt u gegevens m.b.t. de diverse omvormprocessen en in VM 111 "Materialen" worden de hierbij gebruikte materialen behandeld. Deze voorlichtingspublicatie is een update van de in 2000 verschenen eerste druk, welke toentertijd is samengesteld door de werkgroep "Dieptrekken van dunne plaat, staal, aluminium". In het kader van een updateproject heeft het NIMR, inmiddels M2i (Materials innovation institute) geheten, geld ter beschikking gesteld om deze publicaties te vernieuwen en aan te passen aan de huidige stand der techniek.

An activity-friendly environment may increase physical activity (PA) levels and decrease sedentary behavior (SB). This study investigated associations between socio-demographic characteristics, health-related quality of life (HRQoL), perceived environment and objectively measured PA outcomes. Socio-demographic characteristics were assessed using a questionnaire and HRQoL was measured using the EQ-5D. The Neighborhood Environment Walkability Scale (NEWS-A) was used to assess the perceived environment. SB, light PA (LPA) and moderate-to-vigorous PA (MVPA) were measured using the Actigraph GT3X+. Data from 622 Dutch adults were used in multivariate linear regression analyses to investigate associations between NEWS-A and PA outcomes. Analyses were controlled for socio-demographic characteristics and HRQoL. The presence of attractive buildings was associated with less SB ( = ?0.086, p < 0.01) and more MVPA ( = 0.118, p < 0.01). Presence of destinations within walking distance was also positively associated with MVPA ( = 0.106, p < 0.01). Less crime was associated with less MVPA ( = 0.092, p < 0.05). Interactions between personal and environmental characteristics showed that the absence of PA-hindering characteristics (e.g., heavy traffic) was associated with less SB and more MVPA, but only for residents with problems regarding pain and usual activities. The presence of PA-facilitating characteristics (e.g., aesthetics and destinations) was associated with less SB, more LPA and more MVPA but only for the more advantaged people in society. Results suggest that to reduce health inequalities, it would be more helpful to remove barriers rather than introduce PA facilitating characteristics.

Deze publicatie is gemaakt in het kader van het project "Proceskeuze voor de fabricage van producten met hoge nauwkeurigheidseisen te vervaardigen in kleine series" en verschijnt tezamen met de publicatie "Een vergelijking van het laserlassen met conventionele lastechnieken voor kleine series producten". Het doel van deze publicatie is het ondersteunen van de ontwerper en de werkvoorbereider bij het kiezen van het optimale omvormproces wat betreft technologie en economie. Hierbij dient niet alleen te worden uitgegaan van de eisen die aan het eindproduct gesteld worden, maar er dient ook rekening te worden gehouden met de eisen die opvolgende bewerkingen, zoals lasprocessen aan halffabrikaten stellen.

Formative assessment (FA) is an effective educational approach for optimising student learning and is considered as a promising avenue for assessment within physical education (PE). Nevertheless, implementing FA is a complex and demanding task for in-service PE teachers who often lack formal training on this topic. To better support PE teachers in implementing FA into their practice, we need better insight into teachers’ experiences while designing and implementing formative strategies. However, knowledge on this topic is limited, especially within PE. Therefore, this study examined the experiences of 15 PE teachers who participated in an 18-month professional development programme. Teachers designed and implemented various formative activities within their PE lessons, while experiences were investigated through logbook entries and focus groups. Findings indicated various positive experiences, such as increased transparency in learning outcomes and success criteria for students as well as increased student involvement, but also revealed complexities, such as shifting teacher roles and insufficient feedback literacy among students. Overall, the findings of this study underscore the importance of a sustained, collaborative, and supported approach to implementing FA.

Objective: This exploratory study investigated to what extent gait characteristics and clinical physical therapy assessments predict falls in chronic stroke survivors. Design: Prospective study. Subjects: Chronic fall-prone and non-fall-prone stroke survivors. Methods: Steady-state gait characteristics were collected from 40 participants while walking on a treadmill with motion capture of spatio-temporal, variability, and stability measures. An accelerometer was used to collect daily-life gait characteristics during 7 days. Six physical and psychological assessments were administered. Fall events were determined using a “fall calendar” and monthly phone calls over a 6-month period. After data reduction through principal component analysis, the predictive capacity of each method was determined by logistic regression. Results: Thirty-eight percent of the participants were classified as fallers. Laboratory-based and daily-life gait characteristics predicted falls acceptably well, with an area under the curve of, 0.73 and 0.72, respectively, while fall predictions from clinical assessments were limited (0.64). Conclusion: Independent of the type of gait assessment, qualitative gait characteristics are better fall predictors than clinical assessments. Clinicians should therefore consider gait analyses as an alternative for identifying fall-prone stroke survivors.

Study selection: Randomized controlled trials published after 2007 with (former) healthcare patients ≥ 21 years of age were included if physical activity was measured objectively using a wearable monitor for both feedback and outcome assessment. The main goal of included studies was promoting physical activity. Any concurrent strategies were related only to promoting physical activity. Data extraction: Effect sizes were calculated using a fixed-effects model with standardized mean difference. Information on study characteristics and interventions strategies were extracted from study descriptions. Data synthesis: Fourteen studies met the inclusion criteria (total n = 1,902), and 2 studies were excluded from meta-analysis. The overall effect size was in favour of the intervention groups (0.34, 95% CI 0.23–0.44, p < 0.01). Study characteristics and intervention strategies varied widely. Conclusion: Healthcare interventions using feedback on objectively monitored physical activity have a moderately positive effect on levels of physical activity. Further research is needed to determine which strategies are most effective to promote physical activity in healthcare programmes. Lay Abstract Wearable technology is progressively applied in health care and rehabilitation to provide objective insight into physical activity levels. In addition, feedback on physical activity levels delivered by wearable monitors might be beneficial for optimizing their physical activity. A systematic review and meta-analysis was conducted to evaluate the effectiveness of interventions using feedback on objectively measured physical activity in patient populations. Fourteen studies including 1902 patients were analyzed. Overall, the physical activity levels of the intervention groups receiving objective feedback on physical activity improved, compared to the control groups receiving no objective feedback. Mostly, a variety of other strategies were applied in the interventions next to wearable technology. Together with wearable technology, behavioral change strategies, such as goal-setting and action planning seem to be an important ingredient to promote physical activity in health care and rehabilitation.
