    Opis:
    Background: Low bone mineral density is a common finding in children with systemic connective tissue diseases, including juvenile idiopathic arthritis (JIA). The influence of the ongoing process of bone remodeling on the disease course merits further investigation. The aim of this study was to assess the clinical relevance of markers of bone turnover and their potential role as predictors of higher fracture risk and, by extension, risk of osteoporosis. Materials and Methods: Blood samples were collected from 59 patients diagnosed with JIA in order to determine serum levels of the following markers of bone turnover: Beta-Crosslaps, osteocalcin, bone alkaline phosphatase, osteoprotegerin and receptor activator for nuclear factor kappa-B ligand. The values were analyzed with laboratory parameters and results of dual X-ray absorptiometry (DXA). Results: Osteoprotegerin and bone alkaline phosphatase levels were age-dependent. Beta-Crosslaps values were significantly higher in patients with positive JADAS27 score (p=0.0410). Osteoprotegerin levels were higher in patients treated with biological agents than only with disease-modifying anti-rheumatic drugs (p=0.0273). There was no relation between markers of bone turnover and sex, DXA results, dosage of glucocorticosteroids and disease duration. Conclusions: The authors postulate performing DXA measurements every 6 months in patients with higher disease activity. The potential lower fracture risk in children with JIA within biological treatment needs further assessment. Age- and sex-adjusted reference rates of bone turnover markers need to be developed for Central European patients in order to assess individual values properly.

    Opis:
    Przedmiotem artykułu jest ocena  możliwego wpływu pandemii COVID-19 na wybrane sfery życia studentów Uniwersytetu Warszawskiego – ich zdrowie, edukację (która przeniosła się do formuły zdalnej), stosunek studentów do wprowadzanych na poziomie uniwersyteckim, jak i krajowym obostrzeń oraz ryzyko pokrzywdzenia przestępstwem i/lub przemocą.  Ocenę tę przeprowadzono w oparciu o wyniki badania ankietowanego, które zostało przeprowadzone wśród studentów UW w 2021 roku. W artykule przeanalizowano także rozwiązania normatywne wprowadzane przez władze UW w okresie pandemii COVID-19, z uwagi na fakt, że  ich przyjęcie w istotnym stopniu zmodyfikowało model życia i kształcenia społeczności studenckiej.   
    The subject of the article is to assess the possible impact of the COVID-19 pandemic on selected spheres of life of students of the University of Warsaw - their health, education (which has moved to the remote formula), students’ attitude to the restrictions introduced at the university and national level, and the risk of becoming a victim of crime and / or violence. This assessment was based on the results of a survey conducted among students of the University of Warsaw in 2021. The article also analyzes the normative solutions introduced by the University of Warsaw authorities during the COVID-19 pandemic, due to the fact that their adoption significantly modified the model of life and education of the student community.

    Opis:
    The aim of this study is to assess the competitiveness of the Polish agri-food sector for 2004–2017, taking into account its most important sections. It begins with the discussion about the macroeconomic determinants of the competitiveness of the agri-food sector, i.e. the most important external (international) and internal (domestic) factors affecting its competitiveness. Next, the growth of foreign trade in Polish agri-food products is described, both in total volumes and the results in particular groups. The competitiveness of the Polish agri-food sector and its most important sections was assessed on the basis of two quantitative indicators: the trade coverage index (TC) and the revealed comparative advantage (RCA) in exports. The analysis shows that in 2004–2017 agri-food trade in Poland was growing dynamically and the indicators significantly improved in most sections. The authors claim that the improvement of the competitiveness of the agri-food sector in Poland benefited from favourable macroeconomic determinants, both international and domestic ones.

    In Poland, the value of art as a contributor and equal collaborator for business is still either not fully recognized or undervalued. Thus, the aim of the article is to present a set of effective practices and research, highlighting examples from Poland and focusing on areas of creative collaboration beneficial for entrepreneurs, such as employees’ development and empowerment, artistic residences, and investing in artists seen as brands or simply hiring them as chief innovators and inspirers, not only instructors. Finally, the benefits in the field of human capital and communication are briefly discussed to encourage Polish business practitioners to strengthen and extend the art‑business collaboration for the sake of the sustained socio‑economic development.

    Opis:
    The qualitative study presented here was carried out in 2008 as a graduate diploma thesis in Psychology. It was aimed at examining Poles’ experience of living in the United States of America and two European countries, viz. Italy and the United Kingdom. The data consisted of online interviews with ten Poles: 4 from the US, 3 from Italy, and 3 in the UK. The sample was made up of nine females and one male living in the countries in question between 4 months and 17 years (age range 23–36) who had moved from Poland for reasons other than purely economic and, unlike subjects of similar studies on Polish migrants, were also able to speak the host language fluently. The analysis was carried out by means of Interpretative Phenomenological Analysis (Smith, 2003) that allowed to examine the participants’ individual experience of adapting to new social and cultural environments. The results were further analysed and discussed with reference to the relevant literature on the subject of individualistic and collectivist societies (Hofstede, 2001), acculturation (Berry, 2003) and migrants’ identities, as well as earlier studies carried out in the States (Boski, 1992) or in European countries (e.g. Kosic, 2006). The findings were that, regardless of gender and age, the interviewed Poles tended to express respect for the host culture and people and a strong level of identification with Poles in Poland. Despite that strong national identity, however, their level of identification

    Opis:
    In the recycling of WEEE, two approaches are common: a pyrometallurgical or hydrometallurgical treatment, preceded by a mechanical and/or physical separation. In this study, twostep processing of unmodified waste samples of LCD screen inverters was investigated: hightemperature processing followed by acidic leaching under fixed conditions (1M H2SO4, 90 ℃, 1 bar). The analysis carried out concerned a correlation between the type of HT treatment (pyrolysis, incineration, or gasification) and the dynamics of metals’ leaching from samples pretreated this way. It was found that HT method can act as “thermal disintegration”, since it affects, to a varying degree, the structure of the samples and cause elimination of organics and carbonaceous residue (incineration/gasification). The greatest mass loss (~18%) and the most loosened structure was observed for the gasified sample. Varying oxygen potential in HT-processes correlates well with the leachability of thermally treated inverters. The incineration was found to be the most favorable for copper extraction (>95%) by acidic leaching due to oxidized form of Cu, whereas Cu leaching from pyrolyzed and gasified samples needed oxygen and was controlled by the oxygen supply achieving only 36/43% after 6 h. The course of Pd leaching was similar to copper, although with lower efficiencies; 47% of palladium was extracted from the incinerated sample, and only 4 or 7% from gasified and pyrolyzed samples, respectively. Au was leached immediately but only to a slight extent. Contrary to Pb, leaching of Zn, Sn, Sb, and Ni was gradual, probably due to the formation of alloys with copper.

    Opis:
    Used electronic inverters were processed thermally to eliminate organic matrix components through oxidative incineration (IN), oxidative steam gasification (SG), and pyrolysis (PY). Such prepared material was melted at 1250°C with sodium/calcium silicate waste glass under reductive and oxidative atmospheres. The highest Cu recovery in the form of a gravitationally separated metallic phase was found for oxidative smelting of the PY sample and reductive smelting of the IN sample. Recovery of precious metals was analyzed, taking Cu recovery as the reference. It was found that the recovery of Pd was better than copper recovery in each experiment, and the recovery of Au was only in the oxidative smelting of the SG sample and reductive smelting of the IN sample. Recovery of Ag and Cu was similar but only for the reductive smelting of the PY and SG samples. It was demonstrated that Cu, as well as Au, Ag, and Pd recovery, substantially depends on the transport of metals through the metal/slag interface.
