“…After reviewing the responses by the software, a coefficient was obtained, describing the correlation between the responses in the questionnaire and the variation between 0 and 1, based on the analysis of the responses. With a coefficient close to 1, the reliability of the indices is higher (Gottems et al, 2018). If the Cronbach's alpha coefficient is calculated higher than 0.7, it means that data is reliable for analysis (Pinto et al, 2014).…”

“…This coefficient has to be between 0 and 1. If the coefficient value is closer to 1, it means that the response is more reliable (Gottems et al, 2018). If the Cronbach's alpha coefficient is greater than 0.7, it means that the questionnaire can be accounted to be reliable for further analysis (Pinto et al, 2014).…”

According to the roadmap designed by the European Commission (2011), it has become mandatory for the European countries to promote renewable sources to provide their required energy by 2050 (Babonneau et al., 2016; Read et al., 2016). The main goal for this switch from fossil fuels to renewable energy sources, is to mitigate the release of CO2 into the atmosphere (Crotogino et al., 2010; Türkseven Doğrusoy and Serin, 2015; Reuß et al., 2017). However, the utilization of the renewable energy sources (RES) is Centre for Research on Settlements and Urbanism Journal of Settlements and Spatial Planning J o u r n a l h o m e p a g e: http://jssp.reviste.ubbcluj.ro One of the consequences of rapid global population growth is the increase in the energy demand. Currently, the main source of energy for various applications is fossil fuels, which are not renewable and their utilization at large scales have caused a number of environmental issues such as global warming. Hydrogen is one of the main renewable energy sources; however, its utilization has not yet been sufficiently commercialized due to some existing technical issues. For large-scale underground Hydrogen storage facilities, selecting the most suitable setup location is accounted to be a crucial factor in order to use Hydrogen as a promising and environmentally friendly energy carrier. This study aims to develop an expert judgment approach for the prioritization of criteria involving site selection of large-scale Hydrogen storage facilities to support development of modern cities and industries. In this regard, Fuzzy-Delphi methodology was used to prioritize the criteria and sub-criteria, which seemed to be most relevant for the underground Hydrogen storage site selection process. A comprehensive screening was performed in the literature and eighteen criteria from technical, economic, health, safety and environment (HST) and social points of view were extracted. A professional questionnaire was designed for the criteria prioritization and SPSS 25.0 was employed to analyse the achieved results. According to the gained results, the most important sub-criteria were identified as legal restrictions, reservoir permeability and porosity, and regional risks. Also, the findings demonstrated that HSE and technical issues of sustainability for the site selection of H2 underground storage were more underscored in comparison to economic and social criteria. It is concluded that more in-depth studies are still needed to cover more aspects of sustainability regarding site selection for underground gas storages with special focus on social dimensions.

“…Reliability refers to the degree to which an instrument produces consistent results from its scores. When one item is eliminated and Cronbach's alpha coefficient increases, this item is not highly correlated with the others and could be eliminated from the instrument, but if the coefficient decreases, it means that the item is highly correlated with the others [37]. e internal consistency value by Cronbach's alpha was equal to the value obtained in the original instrument.…”

Introduction. The wide variety of symptoms in patients with cardiac arrhythmias can affect daily living activities. The evaluation of symptoms with patient-reported outcome measures (PROMs), with validated instruments, can provide information that contributes to clinical decisions and treatment. In Brazil, however, there is no available scale that evaluates symptoms in different types of arrhythmias. Purpose. This study aimed to translate the Arrhythmia-Specific Questionnaire in Tachycardia and Arrhythmia symptom scale (ASTA-symptom scale) and then validate the questionnaire in terms of Brazilian culture. Method. The methodological process of cultural adaptation used was based on international literature guidelines consisting of forward translation, synthesis, back translation, review by an expert committee, and pretest. Psychometric analyses were conducted with 140 patients. These included measuring internal consistency (Cronbach’s alpha), construct validity with item-total correlations, and convergent construct validity with correlations with the quality of life questionnaire for patients with atrial fibrillation-version 2 (QVFA-v2). Usability and understandability were evaluated through the usability evaluation of instruments. Results. The translation and adaptation processes were performed by obtaining the Brazilian Portuguese version of the original Swedish instrument. This version presented the internal consistency of items, evaluated through Cronbach’s α (0.79). Construct validity was demonstrated by item-total correlations for the nine items, all except one reached the level of >0.30 (0.24). Convergent validity showed a high correlation with QVFA-v2 (0.89). As for the evaluation of usability and understanding, after two small suggested changes, no additional alterations were necessary. Conclusion. The psychometric properties of the Brazilian version of ASTA-symptom scale evaluated in this study were satisfactory, and the scale was proved to be a valid and reliable tool to assess the symptom burden in patients with different forms of tachyarrhythmia. The ASTA-Br-symptom scale questionnaire can be an important addition to PROMs for patients with arrhythmias and could help healthcare professionals in decision-making.
