“…Hence, all scales had a high reliability and could therefore be considered to be a solid foundation for further studies. Umay has also suggested that any indicator with a corrected item-total correlation (CITC) value less than 0.4 should be omitted in order to enhance the overall reliability of the scale [63]. As shown in Table 4, the CITC value of A3 was less than 0.4 and the resulting Cronbach's alpha value when omitting A3 was 0.958 (exceeding the original scale's Cronbach's alpha).…”

Understanding the motivations that stimulate homebuyers’ green purchasing behavior can increase market demand for green products, especially considering the comparably low market share of green products worldwide. In this context, various studies have been conducted examining consumers’ intentions to pay for green products. Nevertheless, there is still limited research on evaluating homebuyers’ purchasing behavior toward green residential buildings. This study argues that the value of green residential buildings (GRBs) affects their adoption, and thus exerts an invisible force on homebuyers’ purchasing behavior. It also finds that field theory provides a scientific perspective on this phenomenon. Thus, this paper proposes a value field model for evaluating homebuyers’ GRB purchasing behavior based on physical field theory and psychology field theory. In particular, physical field theory provides the measurement formula, while psychological field theory explains the effect of the force stimulating homebuyers’ purchasing intention, and ultimately influencing their purchasing behavior. The initial model consisted of a field source (green perceived value), target charge (GRB demand), distance (psychological distance), and value field factor. As the value field factor was calculated to be approximately equal to 1, the final model is a composite of a field source (green perceived value), target charge (GRB demand), and distance (psychological distance). The results validate the construction of the value field model on the basis of field theory. This research contributes to the body of knowledge by analyzing GRB value and provides a clearer understanding of how GRBs and the environment combine to fulfill homebuyers’ requirements and influence their GRB purchasing behavior.

“…[24] It is a wellvalidated tests whose sensitivity and speci city were reported to be high in many studies conducted for stroke patients and recently for healthy older people. [25] GUSS consists of indirect and direct swallowing tests; in indirect swallowing test, the vigilance of the patient, cough and/or throat clearing, and saliva swallowing are observed, while in the direct swallowing test, deglutition, involuntary cough, drooling, and voice change are observed when three types of foods with different consistency, namely semisolid, liquid, solid are provided to the patient. It classi es the subjects into four levels; 0-9 points: severe dysphagia and aspiration risk, 10-14 points: moderate dysphagia and aspiration risk, 15-19 points: mild dysphagia and aspiration risk, 20 points: normal.…”

Background Dysphagia after hip fracture is a common disease that causes malnutrition and aspiration pneumonia, which aggravate treatment outcome of patients. Therefore, the purpose of this study was to assess (1) the prevalence of dysphagia in elderly patients who underwent hip fracture surgery using videofluoroscopic swallow study (VFSS), (2) accuracy of screening test compared to VFSS, and (3) relationship between dysphagia and several factors, including sarcopenia. Method A total of 72 patients over the age of 60 who underwent a surgery for fragility hip fracture from February to September 2019 were included in this prospective study. Gugging Swallowing Screen (GUSS) and VFSS were performed in all patients to assess the swallowing function. Sarcopenia, history of various diseases, nutritional status, bone mineral density, and Koval grade, which can measure preoperative gait ability, were assessed to identify factors associated with dysphagia. Results VFSS results showed diagnosis of dysphasia in 55 (76.4%) patients, and penetration and airway aspiration were observed in 30 (41.7%) and 8 (11.1%) cases, respectively. The median value of GUSS was 19 points (range, 17–20) and 18 points (range, 14–20) in the dysphagia and non-dysphagia groups, respectively, and there was no statistically significant difference (p = 0.189). When dysphagia diagnosed by GUSS was compared to that of VFSS, the sensitivity and specificity of GUSS was 62% and 47%, respectively (positive predictive value 79%, negative predictive value 28%) Logistic regression analysis showed that dementia (OR10.56, CI 1.67 ~ 66.7) was associated with aspiration. SMI, grip strength, and sarcopenia were not associated with dysphagia; however, preoperative Koval grade was a factor that was associated with dysphagia (OR 2.36, CI 1.01–5.55). Conclusions GUSS showed mild dysphagia or normal findings in most patients, and the accuracy was not high. Therefore, VFSS is recommended to diagnose dysphagia and prevent complications for fragility hip fracture patients with a decreased gait ability who are likely to develop dysphagia.

“…Quantitative evaluation and diagnosis are needed to improve accuracy in determining the suggestion of a rehabilitation scheme for patients (Saitoh et al 2018). Some screening tests based on eating assessment performed by a qualified clinical person were reported with several test approaches, such as 10-item Eating Assessment (EAT 10), volume viscosity swallow test (VVST), and the Gugging Swallowing Screen (GUSS) (Benfield et al 2020;Umay et al 2019).…”

Quantitative evaluation of stroke patients with the risk of swallowing disorder or dysphagia is required to support diagnosis and further rehabilitation planning. Fluoroscopy X-ray imaging usually is used for swallowing diagnosis, though it gives radiation exposure to patients. Therefore, quantification of muscle coordination patterns involved in swallowing based on surface electromyography (sEMG) was introduced. However, an adequate quantification of sEMG for dysphagia diagnosis still lacks standardization. In this work, potential sEMG signal features, namely the contraction duration (DUR), the time to peak of maximum contraction (TTP), and the total RMS power (TP), were further investigated to evaluate the swallowing processes in healthy subjects and post-stroke patients. The experimental scheme instructed the participant, i.e. 20 healthy subjects and 20 patients, to swallow 3 mL of water in normal swallowing mode and swallow saliva in dry swallowing mode. The proposed signal processing procedure helps to establish the feature extraction of the three features mentioned earlier. For dysphagia assessment, with the support of our proposed signal processing procedure, DUR and TTP can be used together to improve diagnosis reliability. The characteristic of both features in healthy subjects was shorter than in post-stroke patients. Also, the TP feature is useful as additional information to evaluate the role of suprahyoid (SUP) and infrahyoid (INF) muscle groups which are very important in the swallowing process. These results are promising to provide a reliable set of features in the time domain for swallowing analysis. Notably, this can also be utilized as a feature for supporting the automatic classification of dysphagia diagnosis.
