The paper contains an analysis of the evolution of the instrument of structural benefits in Poland, presents an assessment of the instrument's role in 2002-2007 and identifies factors that exert an influence on the farmers' interest in structural benefits. The analysis is based on the results of surveys conducted with the help of questionnaires by the Institute of Agricultural Economics and Food Economy - the State Research Institute (IERiGZ-PIB), which covered a sample of 3,705 family farms, and on the data collected by the Agency for the Restructuring and Modernisation of Agriculture (ARiMR) and by the Farmers' Social Insurance Fund (KRUS). For the purpose of evaluation of the role played by structural benefits the author has also examined relevant legal acts and national plans for the development of rural areas. Unlike the amount of financial means earmarked for structural benefits and unlike the so-called criteria of access for beneficiaries the principal goals of this agricultural policy instrument have not changed since the moment of its introduction. Following Poland's accession to the European Union the number of beneficiaries has grown considerably owing to the liberalization of legal regulations and increased budget. The analysis has revealed regional differences in the use of structural benefits by farmers.

This paper investigates the noise levels present at various points in the FOSREM type fiber optic seismograph. The main aim of this research was to discover magnitudes of noise, introduced by various components of the analog and optical circuits of the device. First, the noise present in the electronic circuit without any optics connected is measured. Further experiments show noise levels including the detector diode not illuminated and illuminated. Additional tests were carried out to prove the necessity of analog circuitry shielding. All measurements were repeated using three powering scenarios which investigated the influence of power supply selection on noise. The results show that the electronic components provide a sufficient margin for the use of an even more precise detector diode. The total noise density of the whole device is lower than 4⋅10⁻⁷ rad/(s√Hz). The use of a dedicated Insulating Power Converter as a power supply shows possible advantages, but further experiments should be conducted to provide explicit thermic confirmation of these gains.
