Opis: This dissertation focuses on examining how innovations in communication technologies impact the way we communicate on a hyperpersonal level. The concept of hyperpersonal communication refers to communication that takes place through technological platforms, potentially surpassing the effectiveness of traditional face-to-face communication. Given the increasingly sophisticated communication technologies, new and increasingly important questions arise about how these technologies change our communication and relationships with others. This dissertation conducts a detailed analysis of how innovations such as 5G technology can affect hyperpersonal communication and the possible social implications of this phenomenon. The aim is to provide a deeper understanding of this relevant topic and to contribute to the scientific literature in this field. To better understand this topic, we conducted extensive research using a survey questionnaire. Individuals of different genders, age groups, education levels, years of work experience, employment status, and types of employment were surveyed. The survey questions focused on the types of communication technologies people use most frequently, which provide them with the highest level of privacy, how they perceive the impact of innovations in communication technologies on the quality of their communication relationships, and how they use technologies for hyperpersonal communication. Additionally, the dissertation explores how people assess their ability to control the information they share during hyperpersonal communication, in which situations they prefer hyperpersonal communication over interpersonal communication, and how they evaluate the impact of innovations in communication technologies on their ability to build deeper relationships with others. Throughout this dissertation, the complex relationship between people and communication technologies is illustrated, with particular emphasis on the impact of these technologies on the quality of communication and the ways in which people use and adapt to these technologies.

Opis: Magistrska naloga obravnava uporabo virtualne resničnosti pri obravnavi šolske anksioznosti z vidika strokovnjakov s področja duševnega zdravja otrok in mladostnikov. Namen raziskave je ugotoviti, v kolikšni meri strokovnjaki poznajo in uporabljajo virtualno resničnost v svoji terapevtski praksi, ter raziskati njihovo pripravljenost za vključevanje te tehnologije v svojo delovno prakso. Raziskava temelji na kvantitativnem pristopu, pri čemer so podatki zbrani z anketnim vprašalnikom. Rezultati pokažejo, da je poznavanje virtualne resničnosti kot terapevtskega orodja med strokovnjaki zelo nizko, njena uporaba pa v terapevtskem smislu sploh ni prisotna. Končne ugotovitve kažejo, da ima virtualna resničnost pri obravnavi šolske anksioznosti obetaven, a še ne povsem uveljavljen potencial, ki pred tem zahteva še nadaljnji razvoj strokovnih in institucionalnih pogojev.

Opis: In real environments, copper and other metal surfaces are never clean. Even during active dissolution in corrosion, they are likely to be covered with adsorbed corrosion-relevant species such as O, OH, H, and Cl. To explore the impact of such species on the bonding of imidazole, used herein as an archetypal model of azole corrosion inhibitors on Cu(111), we conducted a systematic computational study based on the Density-Functional Theory. Over 400 diverse adsorption configurations were considered, with close attention paid to the effects of variables such as surface coverage, the type of corrosion-relevant species, and the distance between the imidazole molecule and the corrosion-relevant species. We demonstrate that O and Cl enhance the adsorption bonding of imidazole, while H has almost no effect, and OH either diminishes or has a negligible impact on the imidazole adsorption. The effect of the adsorbed corrosion-relevant species on the imidazole adsorption usually diminishes with the increasing distance between adsorbed species and imidazole, and with decreasing coverage of corrosion-relevant species. We identified three coadsorption effects of O, OH, H, and Cl on the non-dissociative adsorption of imidazole, including hydrogen bond formation, enhancement of the N–Cu bond, and work-function change induced by coadsorbates. We also found that if the coverage of corrosion-relevant species is too high, then the chemisorption of imidazole is prevented either sterically or due to the unavailability of free surface sites. Moreover, our study shows that chemisorbed O and OH species promote deprotonation of azole molecules on the investigated copper surfaces, as exemplified by benzotriazole, imidazole, and Cu(111). The N–H bond cleavage is involved in such deprotonation. By undergoing molecular deprotonation during adsorption, the resulting adsorption states are more stable, which increases the persistence of chemisorbed azole molecules. Our findings demonstrate that deprotonated benzotriazole molecules exhibit stability that is roughly 1 eV higher on O/Cu(111) and OH/Cu(111), compared to an adsorbed intact molecule on bare Cu(111). However, for imidazole, the degree of stabilization is significantly weaker and ranges from 0.1 to 0.5 eV. Further, we investigated the formation of coordination complexes between copper central ions and 19 different N-heterocyclic inhibitor molecules in an aqueous medium, using a cluster/continuum model, which involves a few explicit water molecules and the surrounding water described implicitly. Our results indicate that most of the investigated ligands have the potential to coordinate with Cu(I) and Cu(II) ions, forming stable two- or fourcoordinated complexes, respectively. The thermodynamic stability of these coordination compounds was also evaluated.
