Opis:
With the development of information technology, electromagnetic radiation becomes a tangible view of the physical (wave) environmental pollution. Modern scientific research aimed at the components of the elec tromagnetic environment pollution problems mainly involves the anthropocentric approach. There is no procedure for determining the influence of harmful physical factors on biota, in particular in terms of water (Daphnia magna Straus) and air (Drosophila melanogaster L.) environments. A clear system of rationing of maximum permissible levels of electromagnetic radiation, including volume and ecosystems protected areas has not been developed. The article considers the relevant scientific and practical problem of creating a framework for assessing and predicting the negative impact of electromagnetic radiation on the biota related to ethological changes and teratogenesis. The characteristic of all the constituent elements of the system determines the degree of the negative impact of the induction of the magnetic field on the biota: activity, mortality; reproduction; availability, and frequency of Teratology. A method for determining the activity levels of Daphnia and Drosophila total average activity biota was developed and described. The trajectory patterns of Daphnia motion at low activity in the state of stability, with increased activity in the excited state, were created. The results of the research on the negative impact of electromagnetic radiation of industrial frequency on biota were presented. The critical levels of the magnetic field and noise pollution, which cause the depletion and destruction of the test object, the relationship between ethological changes and the occurrence of mutations depending on radiation levels were determined. The biological test objects were proven to minimize the error of the results of determination of electromagnetic effects on the biota, in comparison with the mathematical methods of research.

Opis:
Many attempts have been made to develop a strategy for regulating forest use consistent with the multifunctional forest model. In this paper we present two proprietary methodologies of regulation of the allowable cutting size in a multifunctional forest in the 60−year time perspective. We assumed that all restrictions of nature protection and non−productive functions of the forest would still be in force. We based the first method on age class tables (TKW), which is faster but less exact in terms of spatial order of felling. The tree stand method (D−STAN) is based on stands spatial order and the cutting direction basis. In both cases, we based the temporal felling order on species rotation age. Comparing the results, we noticed that they present similar trends in the age structure of tree stands in younger age classes. The main discrepancies of the forecast concerns the share of forest stands in a complex structure: the TKW method gave approximately 12,4%, while the D−STAN one produced 5,1%. The latter approach shows that much smaller areas of stands are used for reconstruction. That marker is influenced by the spatial order of cutting used in the D−STAN model. In conclusion, we suggest to return to the big−area clear−cutting system on fresh coniferous habitats. Medium−area clear−cuttings should be brought back on the least fertile fresh mixed coniferous forests and possibly even fresh mixed deciduous forests.

Introduction. E-Health tools allow a medical facility to set a given patient’s data in order using ICT techniques, and the patient to use those techniques when contacting a given organisation. Materials and method. Secondary statistical data was used in the research. The study was carried out among primary health care patients. Mining for affinity rules was done in the R programme. The apriori and inspect functions from the arules package were used. Moreover, any redundant rules were removed from thoseobtained using the afero-mentioned method. Applying the general description of the affinity analysis method onto the survey described herein, it should be stressed that the aim of using affinity analysis was to discover the rules which contain the sub-transaction B={V_6=1} as a consequent. This was determined by the intention to discover associations regarding the knowledge about a uniform information system that the patients under study might have. Results. In the discovered rules, the antecedent most often contained an indication of the need for introducing a uniform solution as regards telemedicine. Moreover, according to the opinions of ‚conscious‘patients, a uniform IT system should improve the work at primary health care institutions, introducing an on-line booking system for visits should improve the productivity and comfort of doctors, and an IT system should provide unambiguous identification of a patient. Conclusions. There is potential in using affinity analysis within e-Health. The example of affinity analysis described in his study led to the discovery of interesting and important (from the point of view of a medical facility) regularities regarding the knowledge and expectations of patients as regards e-Health.

Case description. Five workers (2 males and 3 females) employed in a furniture factory located in eastern Poland developed hypersensitivity pneumonitis (HP) after the pine wood used for furniture production was replaced by birch wood. All of them reported onset of respiratory and general symptoms (cough, shortness of breath, general malaise) after inhalation exposure to birch dust, showed crackles at auscultation, ground-glass attenuations in HRCT examination, and lymphocytosis in the BAL examination. The diagnosis of acute HP was set in 4 persons and the diagnosis of subacute HP in one. Identification of specific allergen. Samples of birch wood associated with evoking disease symptoms were subjected to microbiological analysis with the conventional and molecular methods. Two bacterial isolates were found to occur in large quantities (of the order 108 CFU/g) in examined samples: Gram-negative bacterium of the species Pantoea agglomerans and a non-filamentous Gram-positive actinobacterium of the species Microbacterium barkeri. In the test for inhibition of leukocyte migration, 4 out of 5 examined patients showed a positive reaction in the presence of P. agglomerans and 2 in the presence of M. barkeri. Only one person showed the presence of precipitins to P. agglomerans and none to M. barkeri. In the inhalation challenge, which is the most relevant allergological test in the HP diagnostics, all patients reacted positively to P. agglomerans and only one to M. barkeri. The results indicate that P. agglomerans developing in birch wood was the main agent causing HP in the workers exposed to the inhalation of dust from this wood, while the etiologic role of M. barkeri is probably secondary. Conclusion. The results demonstrate that apart from fungi and filamentous actinobacteria, regarded until recently as causative agents of HP in woodworkers, Gram-negative bacteria and non-filamentous actinobacteria may also elicit disease symptoms in the workers processing wood infected with large amounts of these microorganisms. The results obtained also seem to indicate that cellular-mediated reactions are more significant for causing disease symptoms compared to those that are precipitin-mediated.

Opis:
In this paper, we present problems with the management of the forests acquired by the State Forests from the State Land Fund. This was particularly an issue in forest districts with a significant share of private forests, e.g. eastern part of Poland. The problem becomes more and more valid because of the latest amendment of the Forest Act in 2016. It gives the State Forests the right of the first purchase of private forests attributed to sale. They may receive forest stands that will generate specific economic problems related to care, conservation, felling maintenance, etc. These are mostly stands with typical features of private forests, resulting from abandoning economic operations, selective acquisition, as well as from the size, shape and neighbourhood of the plots. This study presents the characteristics of almost 2,000 tree stands acquired from the State Land Fund between 1992−2016 by the Siedlce Forest District (SFD), which is a part of the Regional Directorate of the State Forests in Warsaw. SFD has low forest cover (18%), a strong fragmentation of forest complexes and a very large share of private forests (over 75%). The analysis was based primarily on the descriptions of forest stands and the quantitative and qualitative characteristics, presenting at the same time the problems that SFD has with conducting rational forest management in acquired plots. The current status of the forests transferred from the State Land Fund was assessed as unsatisfactory. The main problems in local conditions are: (i) inadequate fixation in acquired parcels next to private forests (difficulty in locating treatments and custody over the State property), (ii) depleted tree stands, (iii) inadequate parcels (too narrow) and (iv) complications related to co−ownership of parts seized plots. The need to carry out joint−assembly works (mainly land consolidation) or to introduce land communities that would facilitate the management of these forests was demonstrated.

The experiment on Zea mays L. cv. Landmark (F1) plants was performed in a greenhouse with UV-B (305–315 nm). The pots with plants were divided into four groups: the first and the second groups were grown, respectively, at low (1.0 kJ m -2 d -1 ) and high (3.0 kJ m -2 d -1 ) biological effective dose of UV-B radiation. Half of the pots of each group were sprayed with 0.1% solution of Asahi SL (the third and fourth groups). The intensity of photosynthe- sis and transpiration, chlorophyll fluorescence, the content of UV-absorbing compounds and radical scavenging activity were measured using DPPH after four and six weeks of UV-B radiation. After six weeks of irradiation with a higher UV-B dose both flavonoid content and antioxidant activity increased by 112% and by 44%, respectively, compared to the plants grown at the lower dose. The plants treated with Asahi SL and exposed to the high dose of UV-B had the content of flavonoids 80% higher than the control ones. Asahi SL decreased scavenging activity in both groups of plants by 17% and 32%, respectively, in comparison with the untreated plants. The intensity of net photosynthesis, the transpiration rate and chlorophyll fluorescence parameters (Fv/Fo, ETR, Rfd) did not differ in most of variants.

Opis:
Nowadays in forestry, we observe an increase in threats that rise the uncertainty and risk of the forest management. This is caused, inter alia, by increasing intensity of forest and environmental damage as well as by the conflict of expectations for the use of forest resources. As a result, there is a problem of achieving the goals of sustainable development and adaptation of the forest ecosystems to new challenges. The aim of the presented study was to assess the regional variety of the need and the urgency of stands conversion. The feature was determined for all stands of the State Forests older than 20 years. Three assessment criteria were selected: (A) silvicultural target (compatibility of the species composition with the planned one), (B) stands stability (resultant from 5 auxiliary sub−indices), and (C) stock level (including 2 auxiliary sub−indices). The majority of stands has consistent species composition (over 60% in total), however only a small fraction of stands was found with a species composition incompatible with the planned one (average 6.34%). Stands with medium stability accounted for about 70%, while those with poor growing stock status make up about 70% of stands under analysis. The regional diversification of the needs for stands reconstruction seems to be strongly correlated with the incompatibility of stand’s species composition with habitat conditions. The largest fraction of stands requiring conversion was observed in Wrocław, Kraków and Katowice regional directorates of the State Forests. This situation may change in the future due to dynamic changes resulting from modifications of the climate and the deterioration of health condition of dominant Scots pine stands in central and north parts of Poland. Private forests were not taken into consideration in this research. It may impact the overall picture in regions of the high share of private forest ownership.
