    Use of orthopedic implants (OI) and dental implants (DI) is increasing due to obesity and ageing of the population. To increase the bio-functionality of metallic biomaterials, used for OI and DI, it is important to modify their surface composition, roughness, and structure without altering their mechanical properties. Different materials, such as minerals and inorganic compounds are used for coating OI and DI, however, they may cause response of the cells that are in contact with them in the body. To optimize the use of the materials in implant design, it is of interest to study the effect of the materials on cells. Here we present observations of micron-sized particles of milled Al2O3, TiO2 and hydroxyapatite (HA) on human umbilical vein endothelial cells (HUVEC) by scanning electron microscope. We observed morphological changes of the cells – budding of the cell membrane. Comparing to the control, more cells were detached from the glass they were grown on, indicating possibility of increased cell death or inability of the cells to attach to the surface. Described changes can be due to oxidative stress and inflammatory response of the treated cells.

    Wood-polymer composites are increasingly produced through fused deposition modeling (FDM)—an additive manufacturing technique. The versatility of this technology has attracted several industries to print complex shapes and structures. This underscores the importance of studying the mechanical properties of the FDM parts, specifically, their elastic properties. A numerical homogenization methodology is introduced in the present study, focusing on the fundamental aspect of the elastic properties. Investigations were carried out on the influence of various parameters like wood volume fraction, aspect ratio, and internal porosity. The numerical results were validated using analytical models and experimental data. The comparison showed a satisfactory agreement with experimental data, where the relative error did not exceed 10%, leading to a strong conclusion about the validity and effectiveness of the proposed approach.

    We determined the size of differences in stand and tree growth in semi-natural forests with respect to 16 reference soil groups. The forest area of Slovenia (11.8 thousand km2) was used as the study area, and reference soil units were derived from the national soil map at a 1:25,000 scale consisting of 10,781 polygons with an average size of 117.95 ha. Stand growth was defined as periodic stand basal area increment, while the growth of Norway spruce, silver fir, Scots pine, European beech and sessile oak trees was estimated by the periodic diameter increment of 238,349 dominant trees on 67,061 permanent sampling plots. A linear fixed-effects model and linear mixed-effect models were used for studying stand and tree growth in different site, stand and tree conditions. The soil unit was the dummy variable with Dystric Cambisols set as the reference category. Soil contributed 4.3 % to the explained variability of basal area increment and 4–27 % to the explained variability of the diameter increment of the five tree species. Soil was a stronger driver of stand and tree growth than climate or topography. Stand and tree species production rate on soil units was in the interval of −28 % to +5 % and −47 % to +14 % of that on the reference soil unit, respectively. Stand growth was the highest on Eutric Gleysols and the lowest on Histosols, and tree species generally exhibited the highest and the lowest growth rates on different soil units. We suggest that soil should be considered in growth models and studied interrelatedly with climatic, site and stand variables.

    The article presents the characteristics of the gastronomic offer on tourist farms and its potential for the development of gastronomy (wine and food) tourism in rural Slovenia. Although this potential has already been recognized and repeatedly highlighted in various strategic development documents, no comprehensive research has been conducted at the national level to evaluate the gastronomic aspect of the offer in the context of farm tourism as a supplementary activity. Gastronomy certainly plays a central role on Slovenian tourist farms and in many ways represents a key link between the agriculture and tourism. At the end of 2020, there were a total of 4,930 agricultural holdings in Slovenia with at least one supplementary activity registered on the farm, while supplementary activities of farm tourism are carried out on 1,215 agricultural holdings. Most of these agricultural holdings (957 or 78.8%, respectively) offer accommodation, food and drink, which is particularly important for the development of gastronomy tourism in Slovenian rural areas. Using a survey (conducted from November 2021 to February 2022) on a representative sample of 138 tourist farms from all Slovenian regions, we determined the current food and beverages offer and the inclusion of traditional and local dishes in relation to modern dishes. The interviewed Slovenian farmers see the offer of local drinks and dishes as the biggest opportunity for further development of farm tourism, while other potentials (offer of organic food, collective brands, quality schemes, etc.) are much more in the background.

    In rural areas the overlapping of different functions creates spaces and places where activities and interests of various actors and stakeholders converge herewith the potential for conflict arises. Based on extensive desk research (demographical, socio-economical and spatial analyses) and an e-questionnaire among Slovene municipalities we identified: (1) the areas with the highest potential for the conflict occurrence (2) the most frequent types of conflict (3) which actors/stakeholders are often involved in conflicts and (4) practical solutions to the conflicts in surveyed municipalities. The prediction of conflicts in rural areas is of key importance for policy makers, but even more important is to develop an approach to prevent these conflicts. Paper presents several examples employed in Slovenian rural localities, which address the non-systematic practices used for bridging conflicts.

    This paper will compare the views of Li Zehou (1930-2021) and Theodor W. Adorno (1903- 1969) on the relationship between subject and object of perception and cognition through the lens of neo-Marxist paradigms. First, I will describe the main features and innovations of Marxist epistemology that formed the basis of their aesthetic thought and theories of perception. Then I will outline how Li Zehou's epistemology and aesthetics -particularly with regard to his conception of the subject-object relationship-relate to this Marxist framework. In a next step, I will place Li's respective views in a productive relation to Adorno's concept of the "primacy of the object" and his critique of "identitarian philosophy." In this context, I will point out some inconsistencies in his conception of the possibilities of breaking out of such an identitarian theoretical model and conclude with a preliminary proposal for an alternative solution based on Li Zehou's concept of "subjectality" especially with regard to the dialectic of the subject-object relation. In this context, I will be focusing on the traditional Chinese and Confucian notion of the grasping the proper measure, du 度.

    This paper introduces the philosophical theory of Feng Qi, an important modern Chinese philosopher, who is practically unknown in the West. I argue that his theory of knowledge is not limited to epistemology in the strict and narrow sense, but also refers to ontological and metaphysical issues. The paper shows how Feng Qi integrated ontological and ethical suppositions into the framework of what he called ‘expanded epistemology’. In this way, he offers an innovative solution to several problems, linked to the dichotomous relations of substance and phenomena. The article analyses and interprets his theoretical system in order to highlight that it represents an important contribution to comparative epistemology and its underlying methodology.
