No full textEffectiveness of Online Self-Learning Platforms for Promoting Digital Health Literacy : A Randomized Controlled Trial (RCT)
Full text linkDigital health literacy is a basic requirement for the use of digital health solutions. However, it is not yet sufficiently present among users, so that appropriate programmes are needed to promote it. The aim of this study is to investigate the effect of online self-learning platforms on digital health literacy. In a two-armed randomised controlled trial (RCT) with n = 40, participants were assigned to an intervention group (IG) and a control group (CG). The eHealth Literacy Scale (eHEALS) and an adapted version were used to assess digital health literacy. The effect was compared to before and to the control group after using the online selflearning platform. After the intervention digital health literacy improved in the intervention group (p < .001) in both scores and was higher in eHEALS-Score (p = .047) and eService-Score (p = .000) than in the control group. The results indicate that digital services should become increasingly relevant for promoting digital health literacy in the population
Sichtverdeckungen bei der Annäherung an Kreisverkehre : Untersuchung der Wechselwirkungen zwischen Streckenverlauf, Fahrzeugparametern und physiologischen Einflussfaktoren
No full textKreisverkehre gelten als besonders sichere Lösung zur Gestaltung von Verkehrsknotenpunkten. Dies ist insbesondere in der Unterbrechung der durchgehenden Fahrbahn und der damit einhergehenden Verringerung der Fahrgeschwindigkeit begründet. Der Umbau eines Verkehrsknotenpunktes zu einem Kreisverkehr führt deswegen meist zu einer Verringerung der Unfälle im Zusammenhang mit Kfz-Fahrern und Fußgängern. Rad- und Motorradfahrer profitieren dagegen weniger von der Gestaltung des Knotenpunktes als Kreisverkehr. Hier kommt es vermehrt zu Sichtverdeckungen, die eine Wahrnehmung der Verkehrsteilnehmer im Kreis, aus dem sich annähernden Pkw, erschwert.
Diese Masterarbeit beschäftigt sich mit der Analyse verschiedener Einflussfaktoren auf die Sichtverdeckungen. Hierzu werden Streckenverlauf, Fahrzeuggestaltung und physiologische Faktoren in theoretischen und empirischen Untersuchungen betrachtet. Die Analysen zeigen, dass insbesondere der Öffnungswinkel der A-Säule und die Größe des Fahrers hohen Einfluss auf die Sichtverdeckungen haben. Je näher sich das Auge des Fahrers an der A-Säule befindet, desto größer wird der Bereich, der von der A-Säule verdeckt wird.
Darüber hinaus decken sich die Ergebnisse der theoretischen und empirischen Untersuchungen. Dies bedeutet für die Praxis der Unfallanalytik, dass zur Rekonstruktion solcher Unfälle theoretische Simulationen gültig sind und die Realität gut widerspiegeln.Roundabouts are regarded as a particularly safe solution for the design of traffic junctions. This is primarily attributable to the interruption of continuous carriageways and the associated reduction in driving speed. Consequently, the conversion of a conventional junction into a roundabout generally leads to a decrease in accidents involving motor vehicle drivers and pedestrians. In contrast, cyclists and motorcyclists benefit less from the implementation of roundabouts. In these cases, visual obstructions occur more frequently, which impede the perception of vulnerable road users within the roundabout by approaching car drivers.
The present thesis addresses the analysis of various influencing factors on such visual obstructions. For this purpose, roadway alignment, vehicle design, and physiological factors are examined in both theoretical and empirical investigations. The analyses demonstrate that, in particular, the angle of the A-pillar and the driver’s anthropometric characteristics exert a significant influence on visual obstructions. The closer the driver’s eyes are positioned to the A-pillar, the larger the area obscured by it becomes.
Furthermore, the results of the theoretical and empirical investigations are consistent. For accident analysis practice, this indicates that theoretical simulations are valid tools for reconstructing such accidents and provide a reliable approximation of real-world conditions
Plastic-Free Packaging in the German Potted Herb Supply Chain : An Interdisciplinary Assessment of Plant Quality and Consumer Behavior
No full textPlastic packaging has severe environmental consequences but remains dominant in the German potted herb sector. This interdisciplinary study examined both plant physiological performance and consumer behavior to assess the viability of plastic-free packaging for basil, parsley, and mint. We investigated (i) how plastic and plastic-free pots and wraps perform under real production, transportation, and household environmental conditions and (ii) how consumers perceive, use, and dispose of these packaging types in everyday life. Quantitative measurements of temperature, humidity, plant quality, and pot degradation were collected along two supply chains and in 25 households using data loggers and standardized quality assessments. Qualitative insights into consumer practices were obtained through interviews, diaries, photographs, and voice messages during two-week winter and summer household studies. Results show that suboptimal transport temperatures fall below species-specific thresholds, compromising herb quality regardless of packaging type, while plantable pots degrade prematurely under certain cultivation conditions. Although consumers perceive plastic-free alternatives positively, plantable pots were rarely planted and were often disposed of incorrectly. The findings reveal both technical and behavioral barriers that limit the adoption of plastic-free packaging. By integrating upstream supply chain performance with downstream consumer behavior, this study provides insights to guide the development of sustainable, consumer-centric packaging solutions
Strategien zum Wasserrückhalt in der Agrarlandschaft – Analyse und Bewertung umsetzbarer Maßnahmen im landwirtschaftlichen Betrieb
No full textDie Bachelorarbeit untersucht Strategien zur Verbesserung des Wasserrückhalts in der Agrarlandschaft. Ziel ist es, praxisnahe Maßnahmen zu identifizieren, mit denen landwirtschaftliche Betriebe den zunehmenden klimatischen Belastungen – insbesondere Frühjahrstrockenheit und Starkregenereignissen – begegnen können. Auf Basis einer Literaturauswertung und einer betrieblichen Standortanalyse werden verschiedene Ansätze bewertet. Die Ergebnisse zeigen, dass historische Entwässerungsmaßnahmen und der Klimawandel die Wasserverfügbarkeit erheblich beeinflussen. Produktionsintegrierte Maßnahmen wie konservierende Bodenbearbeitung, Zwischenfruchtanbau, Humusaufbau oder Agroforstsysteme verbessern die Infiltrationsleistung und erhöhen die Wasserspeicherung im Boden. Ergänzend tragen landschaftsstrukturelle Maßnahmen – etwa Grabenstaue, Kleingewässer oder Gewässerrenaturierung – zur Retention und zur Förderung ökologischer Funktionen bei. Technische Anpassungen wie eine Regulierung bestehender Drainagesysteme oder die Reaktivierung historischer Wässerstrukturen ermöglichen eine gezielte Steuerung des Wasserhaushalts. Die Analyse verdeutlicht, dass eine Kombination aus betrieblicher und landschaftlicher Ebene erforderlich ist, um die Resilienz gegenüber hydrologischen Extremen zu stärken. Langfristig kann ein integriertes Wassermanagement einen entscheidenden Beitrag zur Klimaanpassung in der Landwirtschaft leisten.The bachelor’s thesis analyzes strategies for improving water retention in agricultural landscapes. Its objective is to identify practical measures that help farms adapt to increasing climatic stress caused by recurring spring droughts and heavy rainfall events. Based on an extensive literature review and a site-specific analysis, various approaches are assessed in terms of their hydrological and economic effectiveness. Results show that historical drainage practices and ongoing climate change significantly affect water availability in soils. Production integrated methods such as conservation tillage, cover cropping, humus enrichment, and agroforestry enhance infiltration capacity and soil moisture retention. At the landscape level, structural measures like ditch weirs, small ponds, and stream and river restoration increase water retention and promote biodiversity. Technical adaptations, including drainage control and the restoration of historical water systems, support targeted water management. The findings highlight that only a combination of field-level and landscape-level actions can enhance long-term resilience to hydrological extremes and contribute to a sustainable, climate-adapted water balance in agricultural systems
Physicochemical and antioxidant properties of baobab seed
No full textThe food security of many sub-Saharan African countries is deteriorating, with the challenges of today further exacerbating this development. Against this backdrop, new and unconventional foods need to be identified that are characterized by their properties as potential solutions. One such interesting option is the baobab tree, whose components (such as the fruit, leaves, and seeds) are already used in many different forms. This review aims to shed light on the characteristics of the baobab tree and the possible applications and composition of its components. The seeds of the baobab tree have been of particular interest, as well as the oil they contain
