No full textEntwicklung und Evaluierung eines Systems zur objektiven Qualitätsbestimmung von unterschiedlichen Rasentypen (Poster)
No full textDie Narbendichte, das Unkraut/Gras-Verhältnis, sowie die Homogenität des Rasens sind visuelle Parameter, die aussagekräftig für den Qualitätszustand einer Rasenfläche stehen. In der gängigen Praxis werden diese, auch nach offiziellen Richtlinien, noch immer mit einem Rahmenmeterquadrat erfasst. Dadurch hat die Subjektivität in der Bewertung einen hohen Anteil. Um bei der Qualitätsermittlung eine objektive Erfassung und Quantifizierung zu ermöglichen, wurde ein System entwickelt, das mittels Kameraaufnahmen und Bildverarbeitung Rückschlüsse darauf ziehen lässt. Die Grundidee basierte auf dem Rahmenmeterquadrat und garantierte durch konstante Belichtungsbedingungen und standardisierte Aufnahmeeinstellungen für eine gleichbleibende Aufnahmequalität. Die Aufnahmen wurden durch einen Bildverarbeitungsalgorithmus verarbeitet und ermöglichten eine Evaluierung der verschiedenen Rasenflächen. Untersucht wurden dabei mehrere Sportplatz- und Gebrauchsrasen. Als Ausgabeparameter wurden Histogramme und statistische Kennzahlen von Boden-, Gras- und Unkrautflächen ermittelt, die direkt eine quantifizierte Qualitätsbewertung der beurteilten Rasenfläche ausgeben. Die jeweiligen Verhältnisse und Verteilungen der Parameter konnten den Deckungsgrad, das Unkraut/Gras-Verhältnis, den Aspekt und auch die Homogenität widerspiegeln
Effectiveness of physiotherapy interventions on individuals with awake and sleep bruxism who report pain as a symptom : a systematic review
No full textBackground: Bruxism is a complex condition that requires an interdisciplinary approach. Not all cases need treatment; it depends on symptoms and their impact. Physiotherapy treatment (PT) has not yet become a natural way to manage symptoms in individuals with bruxism. However, several PT strategies can be potentially helpful, especially for symptoms like pain and tenderness when they are present.
Purpose: To summarize the evidence and explore the effectiveness of physiotherapy for adults with awake and sleep bruxism who present pain and tenderness as symptoms.
Methods: This review was registered in PROSPERO (CRD42021251182). The search was conducted on five databases, limited to randomized clinical trials (RCT) and clinical trials (CT), but not limited to date or language focusing on adulty with any type of bruxism. Two independent reviewers performed all study phases. The risk of bias (RoB) was assessed with the Cochrane RoB Tool-2. Data synthesis was performed based on the bruxism diagnosis (e.g., sleep bruxism, awake bruxism, sleep and awake bruxism, bruxism associated with other conditions), type of intervention, and outcome type. The certainty of the evidence was evaluated using the GRADE approach.
Results: Electronic searches identified 1,745 studies, but only 13 met the inclusion criteria. Five studies included individuals with sleep bruxism (38.5%); two (15.4%) studies, awake and sleep bruxism together; three (23.1%) studies, bruxism without providing a precise diagnosis; two (15.4%) studies, sleep bruxism combined with TMD; and one study (7.7%), had a doubtful diagnosis associated with TMD. For individuals with awake and sleep bruxism, no differences were verified between manual therapy (MT) and MT plus kinesio tape (KT) regarding pain and tenderness. For individuals with sleep bruxism alone, massage plus occlusal splint (OS) was better than massage alone for relieving pain; however, KT did not differ from OS on pain or tenderness. Subjects with sleep bruxism treated with stretching and sleep hygiene advice had less tenderness after treatment than those receiving only sleep hygiene advice. For patients with sleep bruxism combined with TMD, no differences were verified between transcutaneous electrical nerve stimulator (TENS) and OS to relieve pain. However, OS presented better results on tenderness of the masticatory muscles than TENS. Individuals classified as having doubtful diagnoses of bruxism who received microcurrent electrical neuromuscular stimulation (MENS) treatment had significantly better pain and tenderness reduction than those receiving TENS treatment. Most studies (n=10, 76.9%) were considered to have a high RoB; three (23.1%) studies had some concerns. The quality/certainty of the overall evidence was very low.
Conclusions: This review showed positive benefits in subjects with sleep bruxism to manage pain and tenderness when muscle stretching, and MT were combined with other techniques (e.g., OS). This systematic review demonstrates limited evidence of physiotherapy to manage symptoms present in subjects with bruxism (specifically by diagnosis).
Implications: Since the evidence is limited and the certainty in the results is very low, we recommend that clinicians use combined approaches (massage therapy and OS as well as MT for the masticatory muscles combined with KT) to manage symptoms in individual with bruxism

From emotion to intention: how mood, food neophobia, and purchase motives shape willingness to buy new broccoli leaf products
No full textPurpose:
This research aims to explore psychological drivers behind consumer acceptance of food innovations, using broccoli leaf products as a case study.
Design/methodology/approach:
A quantitative survey of 1,114 German consumers was conducted. Initially, a correlation analysis was carried out to analyze the relationship between mood, food neophobia, and purchase motives. Subsequently, a regression analysis was conducted to evaluate factors influencing the likelihood of buying broccoli leaf products.
Findings:
The correlation analysis shows that the relevance of purchase motives shifts when mood is taken into account. A positive mood is associated with a focus on sustainability, certification marks and health, while a negative mood emphasizes price and convenience. Both positive and negative moods are closely linked to brand and design. The regression analysis confirms that positive mood and food neophobia are significantly related to the willingness to buy broccoli leaf products. In addition, factors such as openness to particular dietary styles, a physically active and sustainability-oriented lifestyle, an urban living environment, and a higher education also promote consumer acceptance of such innovative products.
Research limitations/implications:
The analysis is based on correlation and regression analyses. For future investigations, the findings suggest that psychological aspects, particularly mood, should be given greater emphasis in consumer research.
Originality/value:
The study contributes to a deeper understanding of how mood, food neophobia, and purchase motives are associated with consumers' behavioral responses to innovative foods
A CGRA frontend for bandwidth utilization in HiPReP
No full textWhen dealing with multiple data consumers and producers in a highly parallel accelerator architecture the challenge arises how to coordinate the requests to memory. An example of such an accelerator is a coarse-grained reconfigurable array (CGRA). CGRAs consist of multiple processing elements (PEs) which can consume and produce data. On the one hand, the resulting load and store requests to the memory need to be orchestrated such that the CGRA does not deadlock when connected to a cache hierarchy responding to memory requests out-of-request-order. On the other hand, multiple consumers and producers open up the possibility to make better use of the available memory bandwidth such that the cache is busy constantly. We call the unit to address these challenges and opportunities frontend (FE).
We propose a synthesizable FE for the HiPReP CGRA which enables the integration with a RISC-V based host system. Based on an example application, we showcase a methodology to match the number of consumers and producers (i.e. PEs) with the memory hierarchy such that the CGRA can efficiently harness the available L1 data cache bandwidth, reaching 99.6% of the theoretical peak bandwidth in a synthetic benchmark, and enabling a speedup of up to 21.9x over an out-of-order processor for dense matrix-matrix-multiplications. Moreover, we explore the FE design, the impact of the different numbers of PEs, memory access patterns, synthesis results, and compare the accelerator runtime with the runtime on the host itself as baseline
