    Opis:
    The environment resistance potential is defined as the ability of the landscape to limit the negative pollutant impact consisting a.o.in the limiting, by means of accumulation, of the amount of pollutants circulating in the environment system. In practice, their quantity is contigent on the proporties of the components, which are capable of a relatively long-lasting chemical substance accumulation (thus, above all, the properties of the soil cover). The forecast model of environment changes describes the mechanisms and distribution rate of pollution in the soil profile and the interaction with the functional landscape structure. The methodological assumptions, determining of the real, complex diagnosis of the environment condition and for forecasting of the effects of the persisting anthropopressure and for establishing the necessary measures limiting the progressing degradation. Knowing, even approximatively, the mechanism of the existing changes one can determine the optimal (under circumstances) level of pollutant input, and when its limitation is impossible, one can control the use of the environmental potential in such a way as to minimize its negative impact.

    Opis:
    The aim of this study was to present basic trends in population processes in rural areas of the Świętokrzyskie Voivodeship. With the period of 2003-2008 the main subject focused on changes in population size, elements responsible for the character of population changes with components of natural and migratory movement. Changes in the labour market against changes in the number of people em-ployed and unemployment were also discussed. The analysis proved considerable spatial diversification of the processes in question.Positive population-related phenomena were recorded in municipalities located in a suburban zone, whereas negative phenomena occurred in the outskirts of the area and locations of economic restructuring.

    Opis:
    Cybernetic states of law try to plan each activity – especially migration issues. The planning process has the following question originating in socio-cybernetics in its core: Where can it be assumed that the population characteristics are higher/lower than rational? The planning levels can be different: from the continent or country levels via statistic regions or micro-regions to settlements (even at the street and house levels). Parallel to the aggregation like population density (or annual growth rate), models can also be developed for arbitrary layers of demographical statistics, like the required ratio of males and females in different age-groups and/or education categories, etc. The models can analyze time-periods (e.g., years, time intervals) to ensure that dynamic processes will not actually be covered through static evaluation. The necessary data asset (a kind of Big Data) is given by OECD/ EUROSTAT, for example The questions and data assets are well-known. The modeling methodology consists of potential know-how: through estimations of staircase functions in the framework of online similarity analyses, regional norm values can be derived for targeted population characteristics. Therefore, the European strategy concerning the integration of massive volumes of migrants can be supported in an objective way. Analogue analyses with the same methodology have already been derived for parts of Germany and Hungary. Similarity analysis is an artificial intelligence-based approach with its own consistence-oriented quality assurance layers. The data-driven policy creation needs methodologies where objectivity is provided through optimization in the modeling based on arbitrary phenomena. The modeling philosophy should try to ensure a kind of regional multi-layered equilibrium (sustainability, cf. Kazohinia). The outlined methodology can be seen as a sort of automated SWOT analysis where each conclusion will be derived from the raw statistics in a direct way – without the risk of human subjectivity intervening in the process. The modeling spectrum consists of three levels: (1) Explorative modeling is able to derive basic characteristics for ceteris paribus perspectives through the complex functions. The standard analytical potential works with ceteris paribus parameters, based on the appropriate literature sources. (2) Antidiscriminative modeling is capable of deriving ranks for objects without an actual learning pattern, for the so-called production functions. (3) A cybernetic state of law should be able to have robot-planning values supporting human decision processes. Therefore, 'freedom of press' is basically the capability to explore and publish objective force fields and not to catalyze the spread of subjective evaluations.

    Opis:
    W artykule podjęto próbę ustalenia skali potencjału migracyjnego definiowanego jako chęć/gotowość do wyjazdu z badanego obszaru, uczniów przedostatnich klas szkół ponadpodstawowych. Odwołano się do badań surveyowych, które zostały zrealizowane w szkołach Zielonogórsko-Nowosolskiego Obszaru Funkcjonalnego (Zielona Góra, Nowa Sól, Sulechów). Ustalenia empiryczne wskazują na dużą gotowość uczniów do wyjazdów poza badany obszar. Czynnikami w największym stopniu determinującymi chęć wyjazdu jest typ szkoły (plany migracyjne mają częściej licealiści). Na plany migracyjne nie wpływa miejscowość edukacji, co jest symptomatyczne i pokazuje, że różny potencjał badanych miast (przede wszystkim Zielonej Góry) i tak jest niewystarczający, aby zatrzymać dużą część chcących migrować.
    The article attempts to determine the scale of the potential for migration, defined as the willingness/readiness to leave the studied area, of students in their penultimate year of secondary education. The author presents survey research conducted in schools located in the Zielona Góra – Nowa Sól Functional Area (Zielona Góra, Nowa Sól, Sulechów). The empirical findings show a high willingness of students to travel outside the study area. The factor that most strongly determines the willingness to migrate is the type of school (high school students are more likely to have migration plans). Migration plans are not influenced by the town of education, which is symptomatic and shows that the different potential of the surveyed cities (above all Zielona Góra) is anyway insufficient to retain a large proportion of those wishing to migrate.

    Opis:
    W artykule podjęto próbę określenia czynników, które wpływają na budowanie wykwalifikowanego potencjału ludzkiego Ukrainy w kontekście dostosowania go do warunków gospodarki konkurencyjnej. Najważniejszy składnik budowy zasobów kapitału ludzkiego stanowi wielkość populacji, która zarówno pozytywnie jak i negatywnie wpływa na rozwój potencjału społecznego. Wielkość populacji kształtują zmiany demograficzne takie jak: zmiany w rozmnażaniu się populacji, urodzenia, zgony, ich korelacje, jak również częściowo problemy migracyjne. Na budowanie wykwalifikowanego potencjału ludzkiego państwa wpływają także przedsięwzięcia mające na celu jego rozwój.
    Factors influencing on skilled potential of Ukraine in the cut of of competition ability of economy are investigational. The major constituent of skilled potential is considered - resource through the prism of population. Factors are certain, positively and negatively influencing on development of labour potential of Ukraine. Demographic changes, changes, are studied in character of reproduction of population, birth - rate, death rate, their correlation, and also partly migration. Measures are offered influencing on development of skilled potential of Ukraine.

    Opis:
    In recent years, research of antitumor activity of natural compounds isolated from plant material has increased. Polyphenols have gained significant attention due to their proapoptotic abilities and their involvement in migration and inhibition of metastasis processes. The anticancer effects of polyphenolic extracts of Viburnum opulus fruit against human breast (MCF-7) and cervical (HeLa) cancer cell lines have been confirmed in this study. It was demonstrated that the tested preparations (methanol – M and acetone – A from pomace, juice – J and juice after extraction to the solid phase SPE – PF) show cytotoxic activity and regulate the migration process of cancer cells. The degree of inhibition of cell migration was measured at two times - 24 h and 48 h after addition of the tested preparations. The highest toxicity towards both cell lines was demonstrated by the polyphenol fraction obtained after juice purification SPE (IC50 values at concentration of 63,541 and 19,380 μg/mL for HeLa and MCF cell lines, respectively). At the same time, the same preparation inhibited cell migration the most (nearly 70% compared to controls at both times at the concertation of 15 and 30 μg/mL). All preparations showed the antioxidant ability, but the Viburnum opulus juice (200 and 350 μg/mL) and the preparation after its purification (15 and 30 μg/mL) have larger ability to inhibit the intracellular oxidative stress (30-40%) than preparation obtained from pomace (nearly by 20% at concentration of 20 and 50 μg/mL of M and A). Despite the antioxidative capacity of the preparations, they simultaneously decreased cellular mitochondrial potential. The results obtained indicate the high potential of components of Viburnum opulus polyphenolic compounds can be used in the production of innovative dietary supplements or pharmacological preparations for people with an increased risk or inclination towards developing breast or cervical cancer.

    Opis:
    The article is devoted to the analysis of the directions and mechanisms of adapting the social policy of Belarus to the demographic, migration, communication and technological challenges of modern society. The purpose of the article is to search for social policy mechanisms aimed at developing human potential and stimulating the social activity of citizens. The author analyses the directions of the state’s social policy in the absence of the reproduction of labor resources, an increase in the demographic burden on the ablebodied population, an uneven distribution of labor resources, the emigration of skilled personnel, growth in automation and robotization of production, and a growing need to build effective communication between the government and the population. The article provides an extensive analysis of statistical information, sociological research data, the legislative framework, methods and social technologies of social policy. As a result of the study the author comes to the conclusion that it is necessary to search for new mechanisms for implementing social policy in various fields. Therefore, in the field of demography, it is advisable to search for indirect measures to increase social guarantees for women in order to stimulate fertility, and transform the pension system in order to reduce the demographic burden on the working population. In the field of migration, it is advisable to take government action to prevent the outflow of highly qualified specialists abroad and to return of students who have received education abroad. In the field of social and labor relations existing personnel technologists should be improved and objective methods for evaluating the effectiveness of employees based on a competency-based approach should be introduced. In the field of communication between society and the state it is necessary to inform the public about the current state policy and to organize public discussions of the state initiatives before making them.
