This study explores drivers of fast-food consumption in Romania using the Theory of Planned Behavior. We analyze 532 responses to an online survey and use partial least squares path modeling to estimate the relationships between the intention to consume fast food and its possible determinants. Our results show that the most significant predictor is the subjective norms (injunctive norms: β = 0.218, p < 0.001; descriptive norms: β = 0.192, p < 0.001). Among the affective and cognitive attitudes, only the latter is statistically significant in predicting the intention (β = 0.088, p = 0.020), while perceived behavioral control is not significantly associated with intention toward fast-food consumption. We explain how our results can help policymakers to design better interventions on public health concerns about fast-food consumption and population obesity, especially children obesity.
The purpose of this study was to design a new nanosystem for catheter surface functionalization with an improved resistance to Staphylococcus aureus ATCC 25923 and Pseudomonas aeruginosa ATCC 27853 colonization and subsequent biofilm development. New 2-((4-ethylphenoxy)methyl)-N-(substituted-phenylcarbamothioyl)-benzamides were synthesized and used for coating a core/shell nanostructure. Their chemical structures were elucidated by NMR, IR and elemental analysis, being in agreement with the proposed ones. Fe3O4/C12 of up to 5 nm size had been synthesized with lauric acid as a coating agent and characterized by XRD, FT-IR, TGA, TEM and biological assays. The catheter pieces were coated with the fabricated nanofluid in magnetic field. The microbial adherence ability was investigated in 6 multiwell plates by using culture based methods and Scanning Electron Microscopy (SEM). The nanoparticles coated with the obtained compounds 1a–c inhibited the adherence and biofilm development ability of the S. aureus and P. aeruginosa tested strains on the catheter functionalized surface, as shown by the reduction of viable cell counts and SEM examination of the biofilm architecture. Using the novel core/shell/adsorption-shell to inhibit the microbial adherence could be of a great interest for the biomedical field, opening new directions for the design of film-coated surfaces with improved anti-biofilm properties.
We tested the Youth Physical Activity Promotion (YPAP) framework on Romanian students in order to identify actionable determinants to support participation in physical activity. Our sample consisted of 665 responses to an online survey, with participants aged 18–23 (mean = 19 years); 70% were women. We used the partial least squares algorithm to estimate the relationships between students’ behavior and possible predictors during the COVID-19 pandemic. Our results indicate that all the theoretical dimensions of YPAP (predisposing, enabling and reinforcing) have a positive and significant impact on physical activity, with two mediating mechanisms expressed as predisposing factors: able and worth. Unlike previous research, we used second-order latent constructs, unveiling a particular structure for the enabling dimension that only includes sport competence, fitness and skills, but not the environmental factors.
Concerning the location of the residence, the opportunities of some special organized places for physical and sport activities, the objective and subjective matters specifically for the social and educational environment, this study aims to determine the free time budget of the students of the University of Bucharest with the main favorite spare-time activities. The method of the questionnaire, the statisticallymathematical method, the method of graphical representation. The two parts of the students that are included in the presentation are the following: 858 girl and 271 boys, from all the study-years, including the master. They are part of the 18 faculties of the University of Bucharest and of the sport and physical education courses. The social issues influence to some extent the motivation for sport activities in the spare-time (the lack of special-organized spaces) and moreover, other issues are the comfort, education and an unorganized lifestyle. From the processing of the data turns out that the questioned students practice the sport activities in their spare-time, mostly in group. However, the subjects from both categories dispose of spare time of between 1 and 4 hour with a percentage of 84,1 % foe girls and 78,2% for boys. The girls prefer the sport activities that are mainly sedentary whereas the boys prefer sport activities.
The existence of specific factors which influence practice of physical activities in adults, and improvement of working places and conditions, after controlling for age and other characteristics. The awareness of the importance of specialized guidance in the field of physical education and kinetotherapy, that can help adults improve their knowledge of it. Organized exercise should result in increased quality of life and professional performance. Research design was cross-sectional, results were based on classical methods of investigation: scientific documentation, questionnaire-based survey, and graphical interpretation. The survey was carried out in 2015 based on a questionnaire designed by the authors, with 20 questions chosen so that the answers were as objective as possible, leading to a high rate of accuracy. There were 42 subjects (59.52% men and 40.47% women), aged between 28 and 59 years which are teaching staff, researchers and auxiliary staff at the University of Bucharest. The study showed that physical maintenance activities elicit most interest from 80.95% of participants, followed by sport activities 26.19%, and therapeutic activities 19.04%. The age distribution is: 45-50 years old 28.57%, 40-45 years old 19.04%, 25-30 years old 16.66%, 35-40 years old 11.90%, 30-35 years old and 50-55 years old both with 9.52% , with 55-60 years old having only 4.7%. Results confirm assumptions, identifying motivational factors of practicing physical exercise in an organized setting, showing the psychological and social reasons that determine adults to do sport.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
