Opis: The Perceived Inventory of Technological Competency as Caring in Nursing (PITCCN) questionnaire has been designed to measure technological competency as caring in nursing practice. It incorporates the use of technology with the fundamental principles of caring that are central to nursing. As there were no psychometrically sound instruments to quantify the concept of technological competency as caring in the Slovene language, we adapted the English version of the questionnaire to the local environment. The goal was to assess the level of psychometric properties of the PITCCN investigated in Slovene hospitals. Methods: Content validity was conducted with eight experts and quantified by the content validity index (CVI) and the modified Cohen’s kappa index. Face validity was assessed through discussions with participants from the target culture in the pilot study. To assess construct validity and internal consistency, a cross-sectional research methodology was used on a convenience sample of 121 nursing personnel from four hospitals. Principal component analysis (PCA) was used to examine construct validity, while Cronbach’s alpha and adjusted item-total correlations were used to measure internal consistency. Results: The content and face validity of PITCCN were adequate. The scale validity index (S-CVI) was 0.97. Cronbach’s α was 0.92, and subscale reliabilities ranged from 0.810 to 0.925. PCA showed four components, which explained more than 73.49% of the variance. Conclusions: The Slovenian version of PITCCN (PITCCN_SI) has good psychometric properties.

Opis: Microplastics (MPs) that are ubiquitous in aquatic environments and industrial wastewater streams have been identified as key hotspots of MP contamination. It is significantly more effective to remove MPs at these points before they enter municipal wastewater streams. This study is an environmental assessment of a novel pilot plant for the removal of MPs and the chemical oxygen demand (COD) from wastewater with a high MP contamination from a plastics manufacturer in Germany. MP removal is based on physical–chemical agglomeration–fixation by organosilanes. Formed agglomerates are separated using a belt filter. The COD is removed by an adsorption process. The resulting MP removal was 98.0 ± 1.1% by mass and 99.9987 ± 0.0007% by particle count, while the COD was reduced by 96 ± 2.7%. The system’s sustainability is evaluated using the Life Cycle Assessment methodology, evaluating system construction, operation, and end-of-life considerations. The current pilot plant is also compared to an optimized circular and sustainable upgrade, where drivers of environmental burdens are eliminated and collected MPs are reused. Significant reductions in environmental impact categories are achieved and the global warming potential is reduced by 96%. This study provides a sustainability assessment of a novel technology and circular solution to remove MPs from highly polluted industrial wastewater.

Opis: The article examines the prospects for the development of an interstate association of BRICS member nations and concludes that it is necessary to expand cooperation in addition to the economic sphere through other areas, in particular, the organization of interaction to combat crime. The article focuses on the fact that an important area of joint cooperation between the BRICS member nations will be activities in the field of security and combating crime. The main promising areas of cooperation between the BRICS member nations in the field of security are formulated and forms of joint activities in these areas are proposed. This area of cooperation of the BRICS member nations should be based on modern information technologies, which is due to the need for coordination of law enforcement activities of the BRICS member nations. The article analyzes the joint system for preventing international crime in the BRICS member nations and concludes that no improvement of this system is possible without appropriate information support for law enforcement based on general principles and approaches. To this end, the necessity of creating a Unified Digital Environment for Law Enforcement Services in the BRICS member nations is substantiated, which implies the speed of achieving the objectives of law enforcement in the BRICS member nations; reduction of corruption risks in this area; as well as automation of individual work processes by replacing a human resource with software. The article describes the concept of a Unified Digital Environment for Law Enforcement Services of the BRICS member nations, substantiates the components that make up its structure. The modern methods of information processing that can be used to build the specified information system are presented. Possible interested users of this environment are highlighted and the capabilities of the Unified Digital BRICS Law Enforcement Services Environment provided to these users are presented.

Opis: An extremely dynamic and fast-moving environment is pushing enterprises to continuous innovation and change. Managing sustainability in a digitalized environment seems to be of central importance for policy makers, as information technologies (IT), in combination with sustainability objectives, offer a wide range of opportunities for positive change. Through a systematic literature review and the application of automated content analysis, this study aims to provide insights into the latest research in the interdisciplinary field of sustainable business models and information systems. The results of the analysis, combined with a researcher’s perspective, suggest that IT, which can be used to achieve sustainability objectives, are already in place and have an infinite number of potential implications in the future. The results suggest that positive economic, social, and environmental changes can be achieved by using IT as long as they are used to identify unsustainable actions and enable positive change. The analysis of research trends revealed a discrepancy between the research in the European Union and the rest of the world and pointed to several avenues for future research.

Opis: One of the aims of education is to produce wise and responsible citizens who are aware of their impact on the environment and can address and solve daily life problems. From this point of view, science education leading to science literacy is helpful for all students, regardless of their future careers. In this paper, we first review the definitions of science literacy in the literature and present the strategies for its development. In Slovenia, we refer to the ongoing national project NA-MA POTI. Most of the strategies studied focus on primary and secondary schools. However, for the development of science literacy in primary and secondary education, teachers themselves must achieve a sufficient level of science literacy. The research was conducted with a small group of prospective teachers, focusing on three components of science literacy: asking research questions, making hypotheses, and designing an experiment. In addition, we analysed the curricula of the science didactics courses in the teacher education program. The findings show a great need for a systematic change in the curricula. Finally, proposals and ideas for improving the curricula for the didactics of science and the syllabus of the Subject teacher study program are presented.
