Opis: Introduction: The development of a family history (FH) questionnaire (FHQ) provides an insight into a patient's familiarity of a trait and helps to identify individuals at increased risk of disease. A critical aspect of developing a new tool is exploring users' experience. Objective: The objective of this study was to examine users' experience, obstacles and challenges, and their views and concerns in the applicability of a new tool for determining genetic risk in Slovenia's primary care. Methods: We used a qualitative approach. The participants completed a risk assessment software questionnaire that calculates users' likelihood of developing familial diseases. Audio-taped semi-structured telephone interviews were conducted to evaluate their experience. There were 21 participants, and analyses using the constant comparative method were employed. Results: We identified 3 main themes: obstacles/key issues, suggestions for improvements, and coping. The participants were poorly satisfied with the clarity of instructions, technical usability problems, and issues with the entry of relatives' data. They expressed satisfaction with some of the characteristics of the FHQ (e.g., straightforward and friendly format, easy entry, and comprehension). They suggested simpler language, that the disease risk should be targeted toward the disease, that the FHQ should include patient-specific recommendations, and that it should be part of the electronic medical records. When discussing what would they do with the results of the FHQ, the participants used different coping strategies: active (e.g., seeking information) or passive (e.g., avoidance). Discussion/conclusion: User experience was shown to be a synthesis of obstacles, overcoming them with suggestions for improvements, and exploration of various coping mechanisms that may emerge from dealing with the stressor of "being at risk."

Opis: The manuscript discusses the investigation of vehicle flow in a predesignated junction byan appropriate traffic flow management with an effort to minimize fuel consumption, the productionof CO2, an essential greenhouse gas (hereinafter referred to as GHG), and related transport costs.The particular research study was undertaken in a frequented junction in the city of Celje, located in the eastern part of Slovenia. The results obtained summarize data on consumed fuel and produced CO2 amounts depending on the type of vehicle, traffic flow mixture, traffic light signal plan, andactual vehicle velocity. These values were calculated separately for three different conditions of traffic flow management. Amounts of fuel consumed were experimentally investigated in real traffic situations, whereas CO2 production was calculated by applying the actual European standardentitled EN 16258:2012 associated with a guideline for measuring emission values, as well as by examining specific traffic flow parameters. The key objective of the manuscript is to present multiple scenarios towards striving to minimize environmental impacts and improve transport operation's economic consequences when implementing proper traffic flow management. As for crucial findings, we quantified fuel consumption and CO2 emissions based on real data on the number and type of vehicles crossing the examined intersection and traffic light switching intervals. The results show that most of the CO2 was produced while waiting and in the accelerating phase in front of traffic lights, whereby in the running phase through the intersection, significantly less fuel was used. This study represents a mosaic fragment of research addressing endeavors to reduce CO2 production in urban transport. Following the experiments conducted, we can see a notable contribution towards reducing CO2 production with known and tested interventions in the existing transport infrastructure. A procedure embracing individual research steps may be deemed as an approach methodology dealing with traffic flow management with an aim to decrease the environmental and economic impacts oftraffic and transport operation; this is where the novelty of the research lies.

Opis: Three different and very small amounts of alumina (0.2, 0.3 and 0.5 wt. %) in two sizes (approx. 25 and 100 nm) were used to enhance the wear characteristics of ZA-27 alloy-based nanocomposites. Production was realised through mechanical alloying in pre-processing and compocasting processes. Wear tests were under lubricated sliding conditions on a block-on-disc tribometer, at two sliding speeds (0.25 and 1 m/s), two normal loads (40 and 100 N) and a sliding distance of 1000 m. Experimental results were analysed by applying the response surface methodology (RSM) and a suitable mathematical model for the wear rate of tested nanocomposites was developed. Appropriate wear maps were constructed and the wear mechanism is discussed in this paper. The accuracy of the prediction was evaluated with the use of an artificial neural network (ANN). The architecture of the used ANN was 4-5-1 and the obtained overall regression coefficient was 0.98729. The comparison of the predicting methods showed that ANN is more efficient in predicting wear.

Opis: In the master’s thesis we researched corporate governance and the quality of corporate governance. Corporate governance and management of organizations stem from the need and the desire for the existence and development of an organization. It is necessary to establish certain kind of monitoring and controlling in organizations, which we define with the term “corporate governance”. Corporate governance is the system of regulating and controlling corporate conduct and of balancing interests of all shareholders and other stakeholders to which company has influence. The interests of directors and shareholders may be in contrast. The purpose of corporate governance is to find a way to satisfy the interest of both, the board of directors and the shareholders, and at the same time to create long-team and sustainable growth for the company. Corporate governance is extremely important for individual organizations and, consequently, for their business. Compering different organizations, their corporate governance is done in different ways. Corporate governance in developed countries and leading economies is certainly different than in smaller and less developed countries. In this case, arises a question what kind of corporate governance can be labelled as “good” or “first-class” corporate governance. In order to improve corporate governance practices, various legal regulations and other forms of binding and less binding rules, recommendations, codes and standards have been developed. Quality is extremely important for organizations, therefore several methods, methodologies and indexes for measuring the quality of corporate governance have been developed. The purpose of methods is to evaluate and compare the quality of corporate governance between individual companies and between different countries. The results can serve for developing measures to improve corporate governance practices. At the same time, findings can serve to modify and supplement existing legislation and recommendations. The corporate governance index, as a measure of the quality of corporate governance processes, can also be one of the important indicators of the company's potential in order to access to new sources of capital and to reduce the capital´s costs in comparison with other companies. The main purpose of the master's thesis is to study corporate governance and its impact on the business of Slovenian and German telecommunication companies. We make comparison between following companies: Telekom Slovenije, d.d., A1 Slovenija, d.d., Deutsche Telekom AG and Telefónica Deutschland Holding AG. The quality of corporate governance in selected companies was measured with the SEECGAN methodology and index. The methodology was designed to measure the quality of corporate governance. It ensures transparency and provides a structured overview of the main areas of corporate governance between different companies. In empirical part of master’s thesis, we found out that Telekom Slovenije, d.d. has "first-class" quality of corporate governance, A1 Slovenia, d.d. has a "good" quality of corporate governance, Deutsche Telekom AG has a "first-class" quality of corporate governance and Telefónica Deutschland Holding AG has a "good" quality of corporate governance. We found out that both countries have companies with “first-class” and “good” corporate governance. The quality of corporate governance is not related to the national origin or country of operation of the company. One of the main finding of the analysis is that there are no significant differences between the quality of corporate governance in specific areas of SEECGAN index in Slovenian and German companies.

Opis: Systems methodology as a support for strategic decision- making will be discussed in the paper. A society will be presented as a complex system, which is comprised of many smaller, complex systems as its component parts. The healthcare system is one of them. The support to the strategic decision-making in a healthcare system will be shown through systems thinking and systems modelling. We will develop models of a healthcare system in frame of a systems dynamics; a qualitative causal loop diagram (CLD), which helps us to discuss the challenges categorically and a quantitative model, which is a simulation model. Both models illustrate the discussed methodology.
