Opis:
The aim of this study was bacteriological assessment of water in dental unit reservoirs – concentration and composition of the aerobe and facultative anaerobe bacterial microfl ora. Reservoir water samples were taken from 25 units. Bacterial fl ora were determined with the plate culture method. Bacteria were identifi ed with biochemical microtests: API 20E, API 20NE (bioMérieux, France) and GP2 MicroPlateTM (BIOLOG, USA). The concentration of total bacteria isolated from one site was 201,039 cfu/ml, on average; the minimum was 22,300 cfu/ml, and the maximum – 583,000 cfu/ml. The following bacteria were identifi ed: Gram-negative bacteria – Brevundimonas vesicularis, Moraxella lacunata, Moraxella spp., Ralstonia pickettii, Sphingomonas paucimobilis, Stenotrophomonas maltophilia; Gram-positive cocci – Micrococcus luteus, Micrococcus lylae, Staphylococcus cohnii, Staphylococcus hominis ss novobiosepticus, Staphylococcus spp., Streptococcus spp.; actinomycetes – Streptomyces albus. The prevailing bacteria were: Ralstonia pickettii (96.46%), found in all the units. Sphingomonas paucimobilis (1.32%) and Brevundimonas vesicularis (1.07%) were the next most frequently occurring bacteria. Bacteria concentration in dental unit reservoirs reached excessive values, and the bacterial fl ora were composed of the bacteria characteristic for water supply systems, opportunistic pathogens, and bacteria of the oral cavity fl ora. Continuous microbiological monitoring of the DUWL water, including application of a disinfecting procedure, is necessary.

Opis:
Many-year studies on aerosols as an infection vector, despite their wide range, ignored dental aerosol. All procedures performed with the use of dental unit handpieces cause the formation of aerosol and splatter which are commonly contaminated with bacteria, viruses, fungi, often also with blood. Aerosols are liquid and solid particles, 50 μm or less in diameter, suspended in air. Splatter is usually described as a mixture of air, water and/or solid substances; water droplets in splatter are from 50 μm to several millimetres in diameter and are visible to the naked eye. The most intensive aerosol and splatter emission occurs during the work of an ultrasonic scaler tip and a bur on a high-speed handpiece. Air-water aerosol produced during dental treatment procedures emerges from a patient’s mouth and mixes with the surrounding air, thus infl uencing its composition. Because air contained in this space is the air breathed by both dentist and patient, its composition is extremely important as a potential threat to the dentist’s health. According to the author, insuffi cient awareness of health risk, working habits, and economic factors are the reasons why dentists do not apply the available and recommended methods of protection against the infl uence of bioaerosol and splatter. Behaviour protecting a dentist and an assistant from the threat resulting from the infl uence of dental aerosol cannot be limited to solated actions. The author, on the basis of the literature and own research, characterizes bioaerosol and splatter in a dental surgery and reviews a full range of protective measures against these risk factors.

Opis:
The aim of the study was to evaluate the live pig market in Poland against the background of the EU. The analysis included the production volume, foreign trade turnover of pork, consumption level, pork purchase prices and cost production. The study used CSO storage and Eurostat data. A valuable source of information was the literature of the subject. Comparative and correlation analysis were used in the study. The analysis show that Poland is one of the most important producers of pork in the European Union. In terms of pork production Poland takes 4th place in the EU after Germany, Spain and France. In Poland, pork also has a dominant position in the structure of meat consumption. In 2017, the average consumption of this type of meat was about 40 kg per person, and was higher than the EU average. The sector of live pig production in Poland is very fragmented. In such countries as Germany or Denmark the production of live pig has greater concentration. The price of live pig in Poland is based on EU prices. They are lower than in Germany, but higher than in Denmark. National pork production is compensated by import. Since mid-2007, Poland is a net importer of pork in terms of meat. In addition, the import of live animals, especially from Germany, the Netherlands and Denmark is increasing. The economic situation on the live pig market from 2014 year was hindered by African swine fever. In order to increase competitiveness, it is necessary to concentrate production and improve its efficiency.
Celem badań była ocena rynku wieprzowiny w Polsce na tle Unii Europejskiej. W analizach uwzględniono wielkość produkcji, ceny skupu żywca wieprzowego, obroty handlu zagranicznego wieprzowiną, poziom konsumpcji, efektywność produkcyjną oraz koszty produkcji. Wykorzystano dane statystyki masowej GUS oraz Eurostat. Cennym źródłem informacji była także literatura przedmiotu. W badaniach zastosowano analizę porównawczą i analizę korelacji. Z analiz wynika, że Polska jest jednym z najważniejszych producentów wieprzowiny w UE. Pod względem produkcji żywca wieprzowego zajmuje 4. miejsce w UE, po Niemczech, Hiszpanii i Francji. W Polsce wieprzowina zajmuje także dominującą pozycję w strukturze spożycia mięsa. W 2017 roku przeciętna konsumpcja tego gatunku mięsa wyniosła około 40 kg na osobę i była wyższa od średniej w UE. Sektor produkcji wieprzowiny w Polsce jest bardzo rozdrobniony. W krajach, takich jak Niemcy, Belgia i Dania produkcję żywca wieprzowego cechuje większa koncentracja. Ceny żywca wieprzowego w Polsce są uzależnione od cen w UE i są niższe niż w Niemczech, ale wyższe niż w Danii. Krajowa produkcja wieprzowiny jest uzupełniana importem. Od połowy 2007 roku Polska jest importerem netto wieprzowiny w ekwiwalencie mięsa. Ponadto zwiększa się import żywych zwierząt, szczególnie z Niemiec, Holandii i Danii. Sytuację ekonomiczną na rynku wieprzowiny od 2014 roku utrudnia afrykański pomór świń. W celu zwiększenia konkurencyjności gospodarstw trzodowych w Polsce konieczne jest zwiększenie koncentracji produkcji oraz poprawa jej efektywności.

Opis:
Introduction. Researchers who study the problems of Internet addiction point out that this dependence is often co-morbid with symptoms of a variety of pathological disorders, including anxiety, depressive, somatization, and obsessive-compulsive disorders. The goal of this study was to compare the severity of psychopathological symptoms in individuals at risk of Internet addiction (according to Young’s criteria) and those not at risk of developing this addiction with respect to gender and place of residence (urban vs. rural). Materials and method. The study included a group of 692 respondents (485 females and 207 males). The average age of the participants was 20.8 years. 56.06% of them lived in urban areas and 43.94% in rural areas. The following instruments were used: a sociodemographic questionnaire designed by the authors, Young’s 20-item Internet Addiction Test (IAT, Polish translation by Majchrzak and Ogińska-Bulik), and the “O” Symptom Checklist (Kwestionariusz Objawowy “O”, in Polish) by Aleksandrowicz. Results. Individuals at risk of Internet addiction showed significantly more severe pathological symptoms than the individuals who were not at risk of this addiction. There were differences in the severity of psychopathological symptoms between people at risk of Internet dependence living in urban and rural areas. Conclusions. Individuals at risk of Internet addiction were found to be characterized by a significantly higher severity of obsessive-compulsive, conversion, anxiety, and depressive symptoms. Persons at risk of Internet addiction who lived in rural areas had significantly more severe psychopathological symptoms, mainly obsessive-compulsive, hypochondriac and phobic, compared to their urban peers.

Opis:
A comparative morphological and anatomical study on the petioles and lamina of 22 taxa (species, subspecies and cultivars) of the genus Philodendron (subgenera Meconostigma, Pteromischum and Philodendron) has been made in order to investigate interspecific differences which may be useful in species identification. All species have bifacial leaves with petioles, amphistomatic with a strongly reduced density of stomata on the adaxial leaf surface. The species differ in the size and shape of their epidermal cells, the distribution and types of stomata and cuticle ornamentation in the lamina, thickness of epicuticular layer, presence or absence of hypodermis, structure of spongy mesophyll, thickness of palisade and spongy mesophyll layers, as well as types of raphides, and in the structure and forms of petioles. A combination of these characters may be useful in species identification. This study shows that there is some variation in petiole and leaf morphological and anatomical characters among the 22 taxa of Philodendron. However, many characters are present in all of them and may be typical of the genus. The study revealed several detailed interesting epidermal and anatomical features that have not previously been reported in the genus.

Opis:
The type and distribution (locations) of calcium oxalate crystals in mature leaves of 19 taxa of Philodendron (subgenera Meconostigma, Pteromischum and Philodendron) were studied. The calcium oxalate crystals were mainly found in the form of raphides, druses, styloids and prisms. The leaves of Philodendron demonstrate the presence of five distinctive raphide crystal types (biforine, thin-walled spindle-shaped, wide cells containing a wide raphide bundle, bundles of obliquely overlapping crystal and unmodified cells with either a single crystal needle or their cluster). Styloids and druses were found in all taxa at varying frequencies. Simple prisms and variations in crystal forms were most frequently observed in the ground tissue in petioles and midribs. This study represents additional data concerning calcium oxalate crystals in Philodendron.
