Opis:
In the light of up-to-date epidemiological data concerning the prevalence of infertility, and also considering the scale of the problem of obesity and proven cause-effect relationship between abnormal body weight and infertility, it is justifiable to undertake the task of systematization of the state of knowledge concerning nutritional correlates of infertility, in order to create a scientific basis for the formulation of the assumptions of a fertility diet. The study is an attempt to systematize the current state of knowledge concerning the importance of energy and structural (qualitative) aspects of nutrition in the prevention and treatment of infertility.

Opis:
Employees’ attitudes to changes and organizational performance have been the subjects of interest of theoreticians and practitioners of management for a long time. However, direct relations between these phenomena are rarely examined. Dynamic changes in organizations providing public services, their striving for enhancement of innovativeness and an increase of organizational performance cause that today this problem acquires special importance. This paper tries to answer the questions: what are employees’ attitudes to organizational changes in public organizations and what are the relationships between employees’ attitudes to organizational changes and public organizations’ performance? These aims will be achieved by presenting the results of literature study and empirical research carried out in public organizations.

Opis:
The pension system in its functioning and activity should be legitimized as an actual condition in performing specific tasks in accordance with the general requirements and expectations attributed to the pension system. In the case of institutions of the pension system, legitimacy should concern both the organization of the system itself ensuring the implementation of basic tasks, e.g. ensuring system security, guaranteeing the solvency of certain benefits, etc., as well as organizations at the level of individual institutions (public and private). The aim of the article is to analyze the issue of legitimizing the pension system from the point of view of institutions operating in the pension system. The article is teoretical and presents a model enabling understanding of the significant problem of legitimization against the background of functioning pension institutions. The study presents the adaptation of the conceptual (semantic) apparatus to the analysis of the legitimacy of the pension system.
System emerytalny w swoim funkcjonowaniu i działalności powinien cechować się legitymizacją jako faktycznym warunkiem w wykonywaniu określonych zadań zgodnych z ogólnymi wymogami i oczekiwaniami przypisywanymi systemowi emerytalnemu. W przypadku instytucji systemu emerytalnego, legitymizacja powinna dotyczyć zarówno samej organizacji systemu zapewniającego realizację podstawowych zadań, np. zapewnienie bezpieczeństwa działania systemu, gwarantowanie wypłacalności określonych świadczeń itp., jak też organizacji na poziomie poszczególnych instytucji (publicznych i prywatnych). Celem artykułu jest analiza zagadnienia legitymizacji systemu emerytalnego z punktu widzenia instytucji działających w systemie emerytalnym. Artykuł ma charakter teoretyczny i przedstawia model umożliwiający zrozumienie istotny problemu legitymizacji na tle funkcjonujących instytucji emerytalnych. Opracowanie przedstawia przystosowanie aparatu pojęciowego (znaczeniowego) do analizy legitymizacji systemu emerytalnego.

Opis:
Public discussions on the Polish pension system clearly indicate the need for further reforms. Numerous studies show that the majority of Poles negatively assess the entire pension system and the activities of individual entities associated with it. With a low level of acceptance of the rules of the pension system and a lack of trust in it, it is difficult to count on the tendency to save citizens for the post-production period, which in the case of the ubiquitous demographic crisis seems to be a priority task for the authorities of all European Union countries. Changes to the pension system should be implemented in conditions of strengthening trust, which can be achieved, inter alia, by building trust in individual institutions, products and the entire system. The aim of the article was to analyse the levels of trust in the Polish pension system. An attempt was made to systematise the determinants shaping trust based on the analysis of Polish conditions. The article was prepared on the basis of a literature review on trust and the pension system.

Opis:
The paper presents an evaluation of the pollutant removal efficiencies of four primary settling tanks that were components of on-site domestic wastewater treatment plants located in the Roztocze National Park in Poland. We studied two four-chamber settling tanks which were elements of the technological lines of activated sludge treatment plants, and two threechamber settling tanks which provided primary treatment in hybrid constructed wetlands. The tests were conducted in the years 2017–2019. During this period, wastewater samples for analysis were collected from the first chamber (raw wastewater) and the last chamber (primary settled wastewater) of each settling tank. We tested the following pollution parameters: total suspended solids (TSS), BOD5, COD, total nitrogen (TN), and total phosphorus (TP). The following mean pollutant removal efficiencies were obtained for the four-chamber settling tanks: TSS – 68.3%, BOD5 – 50.4%, and COD – 49.5%; the three-chamber settling tanks were much less efficient at reducing those pollution parameters: 50.9%, 17.0%, and 2.3%, respectively. Neither the three-chamber nor the four-chamber settling tanks ensured effective elimination of biogenic compounds. In most cases, the concentrations of TN and TP in primary settled wastewater were higher compared to raw sewage, which means that these elements were being released from sewage sludge during treatment. Despite this finding, the study shows that a primary settling tank should be used as a basic component of any domestic wastewater treatment plant, as it ensures a considerable reduction in TSS and organic matter.

Opis:
The work presented the assessment of household wastewater treatment plants with drainage systems on the quality of groundwater in dug wells and deep water wells in the area of 3 selected communes (Drelów, Dębowa Kłoda and Urszulin), located in the Lublin province in south-eastern Poland. The investigations of the physicochemical composition of water from selected 28 dug wells and 2 deep water wells were conducted from June to July 2020, involving 9 measurement series. The microbiological studies consisted in 4 measurement series. The composition of the wastewater from primary settling tanks discharged to soil via drainage systems located in the vicinity of considered wells was also examined on a single occasion. The studies indicate that the water from wells are significantly polluted with ammonia, nitrites, as well as compounds of natural origin: iron and manganese. The presence of microbiological pollution of fecal origin was noted. The studies clearly indicate the possible pollution of the analyzed well waters with domestic sewage discharged to soil via drainage systems. Therefore, it necessary to take the actions aimed at improving the quality of groundwater in the Lublin province, including limitation of drainage systems, especially in the areas with unfavorable subsurface and hydrological conditions as well as low water supply coverage. The need to introduce changes in legal regulations and strategies for the development of technical infrastructure in counties, favoring the most efficient, as well as simple and inexpensive technologies, was indicated.

Opis:
The aim of this paper was to evaluate the influence of anthropogenic pollution on the water quality of the Ciemięga River, which flows through the Jastków commune, located in the Lublin Province in the South-Eastern Poland. The analyses of the river water were conducted in the years 2019–2020. Each year, the samples for physicochemical analyses were collected seasonally (in February, May, August and November) from the seven selected Ciemięga River sampling points found in the following localities: Ożarów, Moszenki, Sieprawice, Jastków, Snopków and Jakubowice Konińskie. In addition, 3 series of microbiological analysis were conducted in 2020. Electrolytic conductivity, total phosphorus, nitrate-nitrogen and sulfates constituted the physicochemical indicators of poor water quality in the river. Their average values exceeded the standards for the 2nd class of water quality. High concentration of these indicators, especially of the total phosphorus, could have been related to the influx of domestic wastewater from agricultural holdings, wastewater flows from agricultural areas as well as soil erosion and leaching. The levels of E. coli bacteria and fecal coliform allocated the Ciemięga River waters to the 4th class of water quality and could result from domestic wastewater flow to the river. In order to improve the water quality of the Ciemięga River, it is necessary to reduce or eliminate point and non-point sources of pollution by means of streamlining of the agricultural areas fertilization, regulating the water and wastewater management, regulating of the waste management, as well as the appropriate spatial policy and landscaping of the water catchment areas.

Opis:
The goal of the present study was to evaluate the efficiency of filters filled with Rockfos for removal of phosphorus (Total-P) from domestic wastewater using, Rockfos is a material obtained by calcination of carbonate-silica rock (opoka) at a temperature of 900 °C. A field study was conducted in two filters with volumes of 2.0 and 0.8 m3 which were components of hybrid constructed wetlands with an average capacity of 2.0 m3/L, located in two national parks in south eastern Poland. Samples of the influent to and the effluent from the filters were analyzed for Total-P concentrations and pH. Eighty sewage samples were tested over a five year study period. It was shown that the test filters removed Total-P with an average efficiency of 31.5% and 30.2% and that they could be successfully used to remove P from domestic wastewater in small wastewater treatment plants.
