Abstract

The chapter deals with the issue of the risk and security management process in public administration, according to the internal audit standards and their requirements. Main legal acts and standards were specified and shortly described. Specially the risk analysis process and security measures selection were emphasized. The possibility to use the software tools for the risk analysis and security measures selection support in public administration was presented. The experiment of OSCAD usage in public administration was shortly described and its results were presented. This experiment shows that the software primarily intended for IT Security Management can be used for risk management in different area as well, for example – in public administration. Some possibilities of further development of risk management supporting tools were proposed.

Abstract

The paper presents two alternative proposals for processing kinematic modular networks. The first method employs the idea of multi-group transformation which may be reduced to setting up a system of conditional equations with unknowns. The kinematic parameters (point motion velocities) are in this case determined after the observations are adjusted, together with point coordinates. The other proposal is based on the classic idea of the parametric method. The theoretical relationships for functional models of the network adjustment for each of the methods have been provided. The practical conditions have been presented for the application of the proposed models (methods) in constructing detailed computational algorithms. The modular network technology may be an appropriate method of geodetic determination of displacements, especially in difficult terrain conditions (slopes, trees, unfavourable exposition to satellite signals).

Abstract

This article addresses issues of mobility and place-making among CEE-born young people who migrated from Poland and Romania to Sweden as children (up to the age of 18). Previous research on intra-EU mobility in other destinations posits this group as 1.5-generation migrants who, due to their mobility at a formative age, experience duality and in-betweenness – with specific effects on their social and familial lives. Inspired by this research, our article examines how mobility to Sweden at a young age (re)shapes young peoples’ connection to and meaning-making of places post-migration. Drawing on two-step qualitative interviews with 18 adolescents and young adults from Poland and Romania, as well as on drawings and photographs as part of the visual materials produced by the participants, the article makes two contributions. First, it integrates the scholarship on children and youth mobility, translocalism and place-making but also deepens these conceptualisations by underlining the role of memories and feelings in young people’s place-making processes. Second, the article suggests that visual methodology is a valuable tool with which to capture the embodied and the material practices of translocal place-making over time. Our findings reveal that most of these young people continue to strongly associate with places from their childhood and country of origin. For some, these places symbolise ongoing transnational practices of visits and daily communication while, for others, these are imaginary places of safety and a right place to be. The findings also highlight the importance of memories and feelings in creating transnational connectivity between the countries of origin and Sweden, as well as in developing coping strategies against the social exclusion and misrecognition which some young people may experience in their new living spaces.

Abstract

Waste lubricating oil (WLO) is the most significant liquid hazardouswaste, and indiscriminate disposal of waste lubricating oil creates a high risk to the environment and ecology. Present investigation emphasizes the re-refining of used automobile engine oil using the extraction-flocculation approach to reduce environmental hazards and convert the waste to energy. The extraction-flocculation process was modeled and optimized using response surface methodology (RSM), artificial neural network (ANN), and genetic algorithm (GA). The present study assessed parametric effects of refining time, refining temperature, solvent to waste oil ratio, and flocculant dosage. Experimental findings showed that the percentage of yield of recovered oil is to the tune of 86.13%. With the Central Composite Design approach, the maximum percentage of extracted oil is 85.95%, evaluated with 80 minutes of refining time, 50.17 °C refining temperature, 7:1 solvent to waste oil ratio and flocculant dosage of 3 g/kg of solvent and 86.71% with 79.97 minutes refining time, 55.53 °C refining temperature, 4.89:1 g/g solvent to waste oil ratio, 2.99 g/kg of flocculant concentration with Artificial Neural Network. A comparison shows that the ANN gives better results than the CCD approach. Physico-chemical properties of the recovered lube oil are comparable with the properties of fresh lubricating oil.

Abstract

This paper presents the Late Glacial stage of the development of the Białe Ługi peatland in the southern Holy Cross Mountains, based on a comprehensive palaeoenvironmental data. A complex analysis of palynology, Cladocera, sed imentology, geochemistry and 14C dating were used. Organic deposition was initiated during the Oldest Dryas. The sedimentary record of the aquatic and terrestrial ecosystems reflects considerable difference between cooler (Oldest, Older and Younger Dryas) and warmer phases (Břlling and Allerřd). Periods of intensified interaction between aeolian processes and peatland are related to stages of disappearing vegetation and changes in aquatic invertebrate communities. We therefore suggest that peatlands were created as a result of local lithological-structural, tectonic, hydrogeological and morphological conditions, and the peatland development rate was largely influenced by changing climatic conditions, which determined local vegetation development, intensity of denudation processes and water level changes. The results validate significance of selection and use of several methods, as well as value of biogenic deposits from the Białe Ługi peatland as archives of past climate change in the Małopolska Upland. Relatively stable water conditions and uninter rupted biogenic sedimentation in the Late Glacial that were provided by the geological structure and relief suggest the studied peatland is a leading one in the region.

Abstract

This paper is devoted to the surname changes performed through administrative channels in the interwar period. The research is based on the announcements of the “Official Gazette of the Republic of Poland” in 1929. The author describes main reasons for the decisions of surname changes taking into account characteristics of avoided surnames and chosen demographic tendencies, especially those connected with the age and profession of applicants. People of Jewish origin, Poles and representatives of other nationalities showed different motives for surname changes. Jews most frequently changed their surnames due to legal reasons — they wanted to legalize the unlawful use of a surname of the so-called ritual father. The changes carried out under the motive of assimilation occurred definitely less often. Non-Jewish applicants changed mainly appellative names, especially those derived from words related to animals. After comparing tendencies occurring before and after World War II one concludes that besides legal and assimilation factors which are particular to the pre-war decades (connected with the ethnic, legal and religious situation of the time), the remaining reasons for the surname changes are universal and do not distinguish the pre-war period from that of the post-war.

Abstract

The results of first investigation (from the formation in 1939) Gliwice Channel of polycyclic hydrocarbons concentration in bottom sediments was given. PAHs is a very important element of pollution for point of view of bottom deposits utilisation. From the Gliwice Harbour during the channel concentrations of PAHs are reduce. The most polluted is section of first 10 km. The highest concentration (7528 μgfkg) was determined in the bottom sediments of Kłodnica River, on the water intake to the channel. The smallest concentration was determined on the section from 19 to 28.9 km of channel (175 to 700 μg/kg ). The section from chemical factory Blachownia to Kozie Harbour has concentrations 946.88 μgfkg to 2254.915 μgfkg. During the every flood-gate-sections the PAHs concentrations were increased. The hydraulic conditions are the agent determining the distribution of PAHs by influent on the organic suspended solids sedimentation.
