Opis:
The leachate coming from the landfill is a serious problem. This is because the leachate water can contaminate the wells of the residents around the landfill. This research was conducted at Jabon Landfill located in Jabon District of Sidoarjo Regency, East Java Province, Indonesia. Jabon Landfill has been operating since 2003 with a controlled landfill system that has triggered environmental risks due to the leachate output. The purpose of this study was to determine the classification of the shallow groundwater quality status based on the pollution index (PI) around Jabon Landfill at a distance of around 250 meters, 500 meters and 1,000 meters from the landfill. The pollution index was determined by analyzing the pollutant concentration consisting of these following parameters: pH, BOD, COD and Fe. The results of the analysis show that the pH parameter had a higher value than the pH at Jabon Landfill of 7.2–7.5. The pH at Jabon Landfill was 6.35. The Fe parameter shows that the value of 1.694 in the groundwater well closest to Jabon Landfill and the wells further away indicates that the Fe concentration was lower for the latter, namely 0.081 at a distance of up to 200 meters. On the basis of the Pollution Index, the highest value was 5.45 at Well 7 is located 196 m from Jabon Landfill. Meanwhile, the well furthest from Jabon Landfill at a distance of 1,000 m showed a lightly polluted status with a Pollution Index of 1.91. The further the location of the well away from Jabon Landfill, the Pollution Index value tended to decrease. This means that the pollution status generally improves. Overall, the pollution status of the 18 wells shows that 2 wells are moderately polluted, 15 wells are lightly polluted and 1 well is in good condition.

Opis:
Water pollution in rivers is still a crucial problem for the countries that use river water as the primary water source. This study aimed to determine the water quality of the Musi river and the content of heavy metals in water, sediment and mussels as well as to predict the water quality of the Musi river in the next five years. The water samples were taken from 18 stations (sampling points) from upstream to downstream to be checked physically, chemically and biologically. Prediction of the river water quality was made using the QUAL2Kw software. The research results show that the Musi River water is categorized as lightly polluted with concentrations of TSS and DO that have passed the threshold. The heavy metals in river water, such as Pb and Cr have also passed the quality standard. The Fe, Mn, and Zn concentrations are pretty high in the sediment. In turn, in mussels, the metals measured were Fe, Cu, and Zn. The prediction results reveal that several values of the river quality parameters will pass the threshold value with the same pattern tendency from each station.

Opis:
The implementation of the European Union Water Framework Directive required a number of tasks to be fulfilled: classifying the various water bodies into different types, defining reference conditions for each of the types and assessing their ecological quality status – this last is based on biological, hydromorphological and physicochemical quality elements of the ecosystem. The paper presents an attempt to estimate reference values in selected areas of Polish coastal and transitional waters as well as in an open sea area following WFD principles. The preliminary eutrophication assessment showed all the assessed areas to be eutrophication problem areas.

Previous studies indicated that poverty was linked to lower quality of life. The aim of this study is to answer on the following question: do children from families with low financial status differ in quality of life, emotions and mood from children living in families with average income? We also tested differences between children living in the city and in the countryside. 129 children aged 12-14 participated in the study. Children from families with low financial status evaluated their quality of life higher, and felt more happiness and love, as well as more positive in mood. Children from the city felt more fear than children living in the country. There were no statistically significant differences between children living in the city and country areas in quality of life and mood.

The quality of surface water in watercourses in the region of Lublin agglomeration was studied in 2012–2014. Biological and chemical indicators of the study for various sampling sites were detected and the resulting values of the indicators were processed statistically. Rivers characterized by small size and the flow and modification of the riverbed. The resulting low values of macrophyte river index and infusorial index pointed to a poor quality of surface waters. Chemical indicators of the quality of surface waters reached low values, only BOD and phosphates reached high values. The river is located outside the city and it is characterized by moderate potential ecological (III quality class), and the river within Lublin is insufficiently potential ecological (IV quality class). Statistical analysis showed high variability index values between the studied positions.

The following article is the third publication presenting the results of a study concerning the professional activity of handicapped people (see: „Nauka” 1/2008 and „Nauka” 2/2008). The purpose of this part of the research was to determine whether there is a relationship between professional status, life satisfaction, and various personal competencies among handicapped people. Apart from this, we also wanted to establish what conditions personal competencies by focusing on social-demographic factors and disability characteristics. The tested competencies were isolated from the administered questionnaire using a factor analysis. Seven factors were found: locus of control, level of aspiration, potential for development, effort invested in development, impulsiveness, stamina, and mood. Analysis of the results leads to the following conclusions: (1) personal competencies are significantly related to professional activity for handicapped people, as is level of life satisfaction, (2) personal competencies are related to external factors shaping the development of handicapped people, such as: dwelling, gender, level of disability, and type of disability.

The purpose of this paper was to assess the influence of the city of Przemyśl on the quality of water in the San River. The water analysis carried out by the Voivodeship Environmental Protection Inspector in Rzeszów as part of the operational monitoring in 2014 and in 2017 was used in the study. The concentrations of selected physicochemical indicators determined in two measurement and control points located above and below the city of Przemyśl were taken into account. For each water quality indicator, the minimum and maximum values were determined and the arithmetic averages from the research period were calculated. In addition, the regularly performed indicators were subjected to a detailed statistical analysis. Box plot graphs show the extreme values, the median and the interquartile range. Water quality has been assigned to the appropriate class and category of surface waters. Selected specific pollutants and priority substances in the river water were also analysed. Only the concentration of benzo(a) pyrene at the measuring points did not comply with the environmental quality standards. It was found that the city of Przemyśl has a small influence on the quality of water in the San River. Although there was a deterioration of water quality at the measurement and control point below the city, its class and category did not change.

Opis:
W Polsce metoda oceny stanu ekologicznego jezior na podstawie makrofitów opracowana została na potrzeby rutynowego monitoringu wód w latach 2005–2006 na zlecenie ówczesnego Ministra Środowiska. Do procesu tego posłużyło 156 jezior. Zbiorniki zostały pogrupowane pod względem różnorodności roślinności oraz parametrów abiotycznych. Wśród nich wyodrębniono cztery grupy jezior makrofitowych: I – jeziora o wodach miękkich (lobeliowe), II – jeziora o wodach bogatych w wapń (ramienicowe głębokie), III – jeziora o wodach bogatych w wapń (ramienicowe płytkie), a także IV – jeziora łęczyńsko-włodawskie. Dla drugiego oraz trzeciego typu, odpowiednio jezior stratyfikowanych i niestratyfikowanych zaproponowano odrębną klasyfikację ocenianą za pomocą Makrofitowego Indeksu Stanu Ekologicznego. Podstawą jego opracowania była metoda makrofitoindykacji roślinności jezior rejonu Laski w Borach Tucholskich zaproponowana przez profesora Mariana Rejewskiego w latach 70. XX w, a udoskonalona w następnych latach przez profesor Hannę Ciecierską. Określała ona bioróżnorodność na poziomie zbiorowisk roślinnych fitolitoralu tworzonych przez makrofity. Metoda ESMI obejmuje zarówno badania roślinności przeprowadzone w terenie z etapem przygotowawczym oraz część polegającą na wyliczaniu samych wskaźników makrofitowych. Indeks przyjmuje wartości od 0, obrazującego zły stan ekologiczny, do 1 odzwierciedlającego stan bardzo dobry. W trakcie wyliczania końcowego indeksu ESMI uwzględnia się parametry takie jak: różnorodność fitocenotyczna, maksymalna różnorodność fitocenotyczna, indeks kolonizacyjny, powierzchnia fitolitoralu obliczona jako suma powierzchni wszystkich zespołów roślinnych oraz powierzchnia samego jeziora. Zarówno poszczególne wskaźniki wchodzące w skład ESMI uwzględniające skład taksonomiczny oraz obfitość makrofitów, jak i sam zespolony indeks, wyraźnie i w sposób kierunkowy reagują na antropopresję. Jako jej główny, ale nie jedyny przejaw przyjęto proces eutrofizacji, dlatego otrzymane wyniki klasyfikacji porównywano różnymi wskaźnikami trofii. Zatem, do oceny stanu ekologicznego jezior podlegających presjom innego typu niż przyśpieszona eutrofizacja, metoda ESMI nie powinna być wykorzystywana, ponieważ nie jest ona podatna na te presje. Podobny problem, jak zauważa profesor Hanna Ciecierska dotyczy jezior o niekorzystnym dla rozwoju makrofitów ukształtowaniu dna zbiornika. W związku z tym powinno potraktować się ocenę ESMI jako szacunkową z założeniem, iż może ona ulec zmianie, np. po zawarciu przeliczenia do wzoru ESMI poprawki na ukształtowanie misy jeziornej. 
Harmonisation of the laws of the Member States regarding the protection of the environment is one of the tasks of the European Union. Poland joined EU in 2004 and took on various commitments for the improvement of water status. In particular, the Water Framework Directive was a major breakthrough in the assessment of aquatic ecosystems. For the classification of stratified and non-stratified lakes Ecological State Macrophyte Index (ESMI) has been used. In Poland, the method for assessing the ecological status of lakes based on macrophytes has been developed for routine water monitoring shortly after joining the European Union. This index is one of the biological elements in the assessment of ecological status. It considers the whole plant communities in the reservoir. The key factor that ESMI reacts to is anthropopressure, which manifests itself as eutrophication. However, it is crucial that the lakes are also subject to different pressures. In this situation, the ESMI rating becomes only an indicative method. The article describes the role, process of evaluation and the most common problems related to ESMI.

Opis:
Artykuł stanowi głos w dyskusji dotyczącej subiektywnej jakości życia, ujmując ją w perspektywie zróżnicowania strukturalnego. Przedmiotem analiz jest subiektywna jakość życia mieszkańców Łodzi w wymiarze globalnym (ogólne zadowolenie z życia) oraz w ujęciu dziedzinowym. Głównym celem artykułu było ustalenie zależności między dziedzinowymi a globalnymi wskaźnikami subiektywnej jakości życia oraz analiza subiektywnej jakości życia w kontekście zróżnicowania statusu społeczno-ekonomicznego. Analizy przeprowadzone zostały w oparciu o dane zgromadzone w trakcie badań surveyowych przeprowadzonych w latach 2011–2012 na reprezentatywnej próbie mieszkańców Łodzi. W opisywanym projekcie badawczym zadowolenie z życia analizowane było na podstawie klasycznego narzędzie pomiarowego – drabiny Cantrila. Drugim komponentem oceny dobrostanu psychicznego była analiza zadowolenia z 12 sfer życia. Poszczególne pytania, które weszły w skład modułu, zostały opracowane przez zespół realizujący projekt w oparciu o ustalenia empiryczne i teoretyczne z dotychczasowych badań. Na podstawie analiz korelacyjnych oraz metodą regresji liniowej i hierarchicznej regresji liniowej ustalono, że subiektywna jakość życia jest silnie skorelowana z oceną własnej pozycji społecznej; subiektywna jakość życia oraz ocena własnej pozycji społecznej są skorelowane z SES; obiektywne zmienne składające się na status społeczno-ekonomiczny i złożony wskaźnik SES mają mniejszą moc eksplanacyjną niż ocena własnej pozycji społecznej dokonywana przez respondentów.
The article contributes to the debate on the subjective quality of life in the context of structural diversity. The object of analysis is the subjective quality of life of the inhabitants of Lodz, Poland, in the global perspective (overall satisfaction with life) and in the contexts of particular fields of study. The main objective of this article was to determine the relationship between field-specific and global indicators of the subjective quality of life and the analysis of subjective quality of life in the context of the diversified socio-economic status. Analyses were carried out on the basis of data collected during the survey study conducted in 2011–2012 on a representative sample of residents of Lodz. In the described research project, life satisfaction was analyzed based on the classical measurement tool – Cantril ladder. Another component of the evaluation of psychological wellbeing was the analysis of satisfaction with 12 spheres of life. Individual questions included in the module were developed by the project team based on empirical findings and results of theoretical research available to date. Based on the correlation analysis, linear regression and hierarchical linear regression analyses, it was established that the subjective quality of life is strongly correlated with the assessment of own social position; subjective quality of life and the assessment of own social position are correlated with SES; objective variables that make up the socio-economic status and the SES index have less explanatory power than the assessment of own social position made by the respondents.

Opis:
Optimal nutrition of sugar beets at critical growth stages is one of the crucial factors for the achievement of their highest yield potential. In the present study, it was presumed that reduced systems of sugar beet cultivation had no effect on the plants’ nutritional status at critical growth stages, on their yield or technological quality. In 2012-2013, two series of one-factorial field experiments with different beet crop husbandry were carried out in order to verify this hypothesis. The cultivation systems of sugar beet crops differed in the postharvest cultivation technology, mulch types and seedbed tillage. Conservation tillage systems were compared with the control treatment, which represented the conventional cultivation system with an application of manure and 35 cm deep autumn ploughing. The plant nutritional status assessment was carried out at two dates corresponding to the following growth stages: BBCH 16/17 (6-8 fully unfolded true leaves) and BBCH 39/40 (row closing). Regardless of the methods of tillage or the year of observation, the results showed that the plants at BBCH16/17 stage were well-nourished with macroelements but malnourished with microelements, mainly iron and zinc. The microelement deficiency in the plants was a result of adjusted soil reaction, which varied from slightly acidic to neutral. At the BBCH 39/40 stage, there was a decreasing trend in the content of leaf macronutrients in the no-tillage systems treatments compared to the conventional tillage with the ploughing depth to 35 cm and manure application. The reduced tillage systems in sugar beet cultivation did not result in either a yield decrease or a worse technological quality of roots. The experimental factor had no significant effect on the content of molassegenic compounds in beet roots. A decreasing trend was observed in the content of α-amino nitrogen and potassium when compared to the traditional cultivation system. The study showed that the choice of a cultivation technology is of secondary importance as long as the plant grows in optimal conditions resulting from an appropriate site selection.

Opis:
For the effective use of the acquired or existing information system (IS) at the enterprise it is necessary to solve the problems relatedto an assessment of the IS quality. The information system is represented as a set of the functional components therefore it is necessary at first to evaluate quality of each of the components, and then get an integral assessment of the entire system. Quite tricky in the processes of IS quality assessment is the ambiguity of existing methods of formation the set of IT-indicators, most adequately characterizing the current state of functioning of the IS. It is necessary to define quantity and the list of IT-indicators (representative selection) which can be used to evaluate the quality of information systems in the enterprise to ensure the accuracy and veracity of quality assessment of IS. For formation of such selection it is offered to use an expert method. Expert's task is to select the criteria for the assessment quality of IS components, the formation of a representative selection of its indicators that best describe the real state of the information system at the enterprise, establishment of weights for IT-indicators, i.e. the importance of each IT-indicator to assess the quality of entire IS. The implementation of such actions, taking into account the recommendations of existing standards and using the method hierarchies’ analysis, are considered.

Opis:
This study focused on the phytoplankton and environment relationships as well as on the ecological and trophic conditions of lakes inhabited by coregonid fish. Studies were carried out in deep and stratified vendace-type lakes called Lake Pluszne and Lake Łańskie (the Olsztyn Lake District, north-eastern Poland) in 2007-2008. Ecological and trophic conditions were determined on the basis of the phytoplankton multi-metric PMPL and Trophic State Index. Both lakes were characterized by a similar thermal and mictic regime, with the occurrence of hypolimnetic oxygen deficits. They were classified as hydrocarbonate-calcium type and medium-sized eutrophicated water bodies. According to the integrated trophy assessment, proposed in this research, the final Trophic State Index TSIAV indicated meso-eutrophy of both lakes, although the phytoplankton-based PMPL indicated that the ecological potential in Lake Łańskie was good and less than good - due to large cyanobacteria biomasses - in Lake Pluszne. The actual loads of phosphorus and nitrogen significantly exceeded permissible levels, especially in Lake Łańskie (5-fold at the most of the P content), at similar morphometric and sedimentation conditions in both lakes. However, more intensive water-exchange rate and more favorable conditions for phosphorus runoff in Lake Łańskie could limit the phytoplankton growth, especially cyanobacteria. Summing up, better oxygen conditions and less abundant phytoplankton suggested that Lake Łańskie had more suitable conditions for coregonids during the surveyed period than Lake Pluszne, where the vendace biomass has recently decreased drastically.

Studies were carried out in deep and stratified vendace-type lakes called Lake Pluszne and Lake Łańskie (the Olsztyn Lake District, north-eastern Poland) in 2007-2008. Ecological and trophic conditions were determined on the basis of the phytoplankton multi-metric PMPL and Trophic State Index. Both lakes were characterized by a similar thermal and mictic regime, with the occurrence of hypolimnetic oxygen deficits. They were classified as hydrocarbonate-calcium type and medium-sized eutrophicated water bodies. According to the integrated trophy assessment, proposed in this research, the final Trophic State Index TSIAV indicated meso-eutrophy of both lakes, although the phytoplankton-based PMPL indicated that the ecological potential in Lake Łańskie was good and less than good - due to large cyanobacteria biomasses - in Lake Pluszne. The actual loads of phosphorus and nitrogen significantly exceeded permissible levels, especially in Lake Łańskie (5-fold at the most of the P content), at similar morphometric and sedimentation conditions in both lakes. However, more intensive water-exchange rate and more favorable conditions for phosphorus runoff in Lake Łańskie could limit the phytoplankton growth, especially cyanobacteria. Summing up, better oxygen conditions and less abundant phytoplankton suggested that Lake Łańskie had more suitable conditions for coregonids during the surveyed period than Lake Pluszne, where the vendace biomass has recently decreased drastically.
