COMPETENCY POTENTIAL
WORK PREDISPOSITIONS OF TELE-WORKER
Opis:
This article describes an online tool for preliminary (self-)diagnosis of personal competency potential from the perspective of telework. It was developed to meet the needs of the EFZ vertical portal (an Internet portal dedicated to flexible forms of employment). On one hand, the article presents the structure of the tool itself, including the implemented appraisal approach that is based on an analysis of a person's internal motivations as well as the proposed model of universal telework attributes. On the other hand, it describes the format of feedback information that is automatically generated by the tool, which is the result of the appraisal of the person's competency potential for undertaking activities of the telework type. The presentation of the tool includes comments interpreting appraisal results that may be obtained on the EFZ vertical portal, for example.

The dynamics of ABCO$\text{}_{4}$ deformable crystals with electroelastic interacting was expressed by theoretical model with wave-linear approximation. The one-dimensional problem was considered assuming that the field variables are represented by plane electroelastic waves. As a result the dispersion equation for these crystals was obtained. Using this model the data concerning the elastic properties of SrLaGaO$\text{}_{4}$ are discussed.

In this paper we present two hyper-heuristics developed for the Cross-Domain Heuristic Search Challenge. Hyper-heuristics solve hard combinatorial problems by guiding low level heuristics, rather than by manipulating problem solutions directly. Two hyper-heuristics are presented: Five Phase Approach and Genetic Hive. Development paths of the algorithms and testing methods are outlined. Performance of both methods is studied. Useful and interesting experience gained in construction of the hyper-heuristics are presented. Conclusions and recommendations for the future advancement of hyper-heuristic methodologies are discussed.

Opis:
The paper describes the results of investigation on the range of trophic abilities and preferences of fungi causing the wood decay of the brown rot pattern. Fomitopsis pinicola, Laetiporus sulphureus, Piptoporus betulinus and Serpula lacrymans fungi were tested. Wooden samples made from wood of 25 different, both European and exotic, tree species were used. They were put on mycelium of every tested fungus. After 30, 60 and 90 days of exposition samples were weighted and the loss of their mass was calculated to compare the differences of wood destroying abilities between examined tree species. The results indicated that the range of trophic abilities in ex situ conditions of tested fungi species was much wider than in nature. All examined fungi were able to decay the wood of more tree species and their trophic preferences occurred to be different as well.

Opis:
Contemporary models of light conditions on the forest floor can be divided into two categories: undercanopy models that allow the light conditions in a stand under the canopy to be simulated, and models that take into account shielding from the side. Under-canopy models precisely estimate the availability of wavelengths of light spatially distributed under the canopy of stands: however these models require a large amount of data on the spatial structure of forest stands. The other class of models describes the light conditions on a particular open surface. These incorporate shielding from the side and are easier to use as they require less data than under-canopy models. In practice, in forest conditions, such models require data on the size, shape, and geographical location of surveyed surfaces (e.g. gaps, and cut areas) and on the height of the surrounding stand. Often, these data are available in databases, such as the State Forest Information System (SILP), can otherwise be obtained relatively easily (and inexpensively). Compared to under-canopy models, these models provide a cheap way to obtain useful information on variation in the light environment that affects the microclimate for regenerating plants on clearcuts and canopy gaps.

Opis:
In most cases, mechanical site preparation (MSP) is a precondition if high−quality (natural or artificial) regeneration of forests is to be achieved. However, the measures involved here may differ in terms of the level of intervention of the soil environment, at both the surface and deeper down. The choice of MSP methods should be based on climatic conditions, site type and the species whose renewal is sought, while the effect should improve conditions for the emergence and growth of the young generation of trees, with the influence on the soil environment being limited as far as possible. The research sought to compare physical and chemical features of the soils of the microhabitats created in clear−cut areas as a result of MSP using either an LPz double mould−board forest plough (furrow and ridge), an active plough (furrow and ridge) and a forest mill (belt and beyond the belt) as compared with unscarified soil. Investigated physical features included grain size (content of sand, silt and clay), bulk density and actual moisture, while the chemical ones: pHH2O and pHKCl, exchangeable acidity, total content of N and C and the C/N ratio, P2O5 content and base cations Mg2+, Ca2+, K+ and Na+. The most invasive MSP method for the soil environment is the active plough, which leaves the ridge exposed to processes of the decomposition of organic matter (and the highest content of N, C, Mg2+, Ca2+ and K+). Equally, this method may pose the greatest threat of mineral components of the soil being leached, with impoverishment of the habitat ensuing. The forest mill in turn offers the least invasive MSP. Most of the physical and chemical features of soil (other than exchangeable acidity and pHH2O and pHKCl) both in the belt areas and beyond them differed little from the those characterising non−scarified soil. Also the analysed features determined for the furrows ploughed by the active or LPz ploughs or the belt prepared using the forest mill did not differ significantly.

The type of the substrate and controlled mycorrhization did not affect the growth of young trees. Oaks treated with Nimrod in the nursery were the tallest after outplanting, but grew slower compared to trees in other variants. The oaks protected with the triazole fungicides (Falcon and Bayleton) in the nursery showed higher level of infestation by powdery mildew in the plantation.

Opis:
Mechanical site preparation is recommended to create optimum conditions for seed germination and seedling growth in a clear−cut area. Lack of soil scarification or less−intense methods may be more suitable from an environmental point of view, but can result in a failure to obtain natural regeneration. This study compared the effects of three mechanical site preparation methods (SPM) characterized by different levels of soil scarification (i.e. double mould−board forest plough (LPz), active plough (PA) or forest mill (FL)), as well as a control variant without mechanical site preparation, on height, density, spatial distribution and survival among naturally regenerating Scots pines (Pinus sylvestris L.) in the first 2 years of growth in a clear−cut area of NE Poland. The experiment was based around a four−block randomized block design involving the four variants. Seedling height was measured at the end of the first and second growing seasons, with measurements performed on 8 meter−wide transects extending across the entire width of the cleat−cut. We found no effect of SPM on seedling height, though the density of seedlings regenerating naturally was found to be dependent. After two years, the highest density was achieved in the PA variant (8.1 seedlings/m2) and the FL variant (7.0 seedlings/m2). A significantly lower density characterized the LPz variant (5.1 seedlings/m2) and the lowest of all the variant without soil scarification (3.2 seedlings/m2). The most homogeneous natural regeneration was achieved following the use of PA (2.6% of 1 m2 plots without seedlings after two growing seasons), while the least homogeneous was the variant without soil scarification (22.4% of 1 m2 plots). Survival of pines after the second growing seasons was quite high (over 80%), and did not differ significantly depending on the SPM. Our research therefore confirmed that, in the absence of mechanical site preparation, natural regeneration of sufficient density and homogeneity cannot be obtained. The best natural regeneration was obtained on sites prepared with PA, and FL scarification being only slightly less favorable. The low density and uneven distribution of seedlings on the soil prepared with LPz was a surprising result. The probable reason for this lay in the high precipitation in the first growing season. On one hand, this provided very good moisture conditions for seed germination and seedling growth on a substrate with high porosity in the PA and FL variants, but on the other the high bulk density of mineral soil in the LPz variant led to oxygen deficit.

The aim of the study was to assess the effect of the application of Sincocin AL and inoculation with the fungi Hebeloma crustuliniforme or Laccaria bicolor on the growth and level of mycorrhizal colonization of Scots pine seedlings. Sincocin had no effect on the development of biometric parameters of pine seedlings inoculated with L. bicolor, it limited the growth of non−inoculated seedlings and stimulated the growth of the seedlings from the variant with H. crustuliniforme. Sincocin did not cause changes in the proportion of the mycorrhizae formed by H. crustuliniforme or L. bicolor, and affected in different ways (stimulation, inhibition, no effect) the spontaneous formation of mycorrhizae.

Opis:
The paper reports on the growth conditions of Li$\text{}_{2}$B$\text{}_{4}$O$\text{}_{7}$ single crystals in both pure and Yb, Co, Mn doped systems. The crystals were grown by the Czochralski method using an intentional concentration of the above-mentioned ions at a level of 0.5 mol.%. The pure and Mn-doped crystals were found to be highly transparent and clear. The crystals doped with Yb$\text{}_{2}$O$\text{}_{3}$ had a lot of precipitations making them opaque. The Co-doped crystals were purple-blue in colour and highly transparent. The growth of Yb and Co doped Li$\text{}_{2}$B$\text{}_{4}$O$\text{}_{7}$ crystals was reported for the first time in this paper. Absorption was measured in the range of 200 to 3200 nm, moreover analysis of changes in the absorption spectrum ofγ-irradiated pure and doped Li$\text{}_{2}$B$\text{}_{4}$O$\text{}_{7}$ crystals was performed. Some thermoluminescence properties were measured, e.g. energies and lifetimes of the traps of different charge carriers occurring in the crystals at low temperatures.

Opis:
Different methods of logging slash management (LSM) and methods of soil preparation (MSP) can create different conditions for the growth of forest trees. This occurs through variation in soil aeration, tree nutrition or microbial conditions. These factors are modified by climate, soil fertility, treats from insects or fungal pathogens and renewed species. The aim of this study was to compare effects of three LSM methods: 1) crushing and mixing with the soil by Mery Crusher, 2) chopping and leaving on the soil surface, and 3) removal from the clear−cut, and three MSP: 1) double−mouldboard forest plough LPz−75, 2) active plough U−162, and 3) forest mill FAO−FAR FV 4088 on biometric parameters, density and survival of six−years old Scots pine seedlings. Field research was conducted in Narol Forest District (south−eastern Poland). The soil in the study area was classified as brown podzolic, formed on loose sands with typical mor humus.The experiment was established by planting 10 000 one−year−old pine seedlings per hectare, after clear cut and followed by a two−factor block design consisting of nine variants distinguished on the basis of LSM and MSP randomly assigned to each of the three blocks. Tree height and root collar diameter were measured three times, at the end of 1st, 3rd and 6th growing season. The results showed no statistically significant differences in the size of the analyzed parameters of planted seedlings. Seedlings in the variant with site preparation by crusher and forest mill were slightly higher and thicker. This indicates the better trophic conditions in that variant. LSM did not affect either seedlings density or their survival. A slightly higher survival rate and tree density occurred in variants with crusher regardless of soil preparation method. It follows that, all presented experimental variants give similar results. Therefore, selection of the most appropriate methods of site and soil preparation should primarily respect ecological and economic indicators, and such local factors as microclimate, mainly precipitation, site fertility and threats from pests and fungal diseases.

Opis:
Paper presents an analysis of phenotypical variation and an evaluation of silvicultural quality of progeny from 27 beech stands around Poland that grow on the provenance plot in the Brzeziny Forest District (51.791997°N, 19.813841°E). The trial commenced in spring 1996, on the basis of 2−year−old saplings with covered root systems. A randomised block method with 3 replications was applied, with subsequent measurements and analyses carried out in 2015, following 20 years of growth. The considered features included height, breast−height diameter, crown habit, trunk curvature and height of branching. Single−factor analysis of variance and Tukey’s HSD test were applied to determine the significance of differences among provenances. The largest mean height was attained by beeches originating from Gdańsk, Szczecinek and Bierzwnik. The least−tall beeches were in turn those whose origins were in Tomaszów, Łagów and Grodzisk. The greatest intra−population variation in height characterised the beeches from Gryfino and Krucz, while the most limited variation was noted for Gdańsk population. The beeches of greatest girth were again those deriving from Gdańsk, Bierzwnik and Szczecinek populations, as well as the one from Kwidzyn 15. The lowest values for diameter at breast height were again noted for the Grodzisk, Tomaszów and Łagów provenances. Marked intra−population variation in this feature characterised trees from the Gryfino, Bieszczady National Park (42), Zdrojów and Krucz provenances. The populations also differered in relation to analysed more−qualitative features. The group of populations prized most in terms of their overall silvicultural quality included Gryfino, Grodzisk, Zdrojów, Bieszczady National Park, Bierzwnik and Szczecinek provenances. In contrast, only low quality was manifested by beeches from Tomaszów, Rymanów, Wejherowo, Młynary, Golub− −Dobrzyń and Kwidzyn provenances. In general, populations originating from the north (especially Pomerania) achieved better growth and a more favourable quality evaluation than those from the south, and sites located near the range limits of the species (fig. 7). The obtained results show that northern Poland boasts the most plastic populations of beech. Equally, it was not possible to establish that populations of local origin were superior in terms of growth to those originating in more far−flung parts of Poland. Furthermore, assessments of different populations in terms of their growth and quality features often proved highly disparate.

Opis:
The paper presents investigation on influence of root shortening on growth of 2−years−old Norway spruce seedlings after their development in the nursery. Measurements of basic morphological features reveal that strong length reduction increases regeneration of spruce root system. Together with that, slight decrease in height and diameter increment of the main shoot can be observed. Shortening of spruce roots improves significantly the balance between above− and belowground parts of the seedlings as well.

Opis:
This paper describes the variability of Scots pine (Pinus sylvestris L.) provenances in the IUFRO experiment located in Rogów (central Poland). The silvicultural quality and growth of 17 European provenances at the age of 28 years were examined, including height, diameter at breast height, standing volume, straightness of stem and health status. Populations from Poland (Spała, Miło−młyn, Rychtal), Germany (Betzhorn, Lampertheim), France (Haguenau) and Hungary (Pornóapáti) characterized by the best growth parameters. In contrast, pines from Northern (Russia, Sweden) and Southern (Turkey, Montenegro and Bosnia and Herzegovina) Europe were smaller and thinner and, as a result, with lower standing volume. The smallest differences of pine populations were found in tree height. The highest mean tree height (11.68 m) was reported for Rychtal (Poland) provenance, while the lowest (6.77 m) for Çatacik (Turkey). The overall mean tree height in the whole experiment was 9.83 m. Diameter at breast height (dbh) varied more than the tree height. The highest mean dbh (129.91 mm) was reported for Haguenau (France) provenance, while the lowest (72.85 mm) again for Çatacik (Turkey). The overall mean dbh for all provenances equaled 107.12 mm. The highest differences of pine populations were found in the standing volume. The highest standing volume (19.05 m3/ha) was obtained for Pornóapáti (Hungary) provenance, while the lowest (163.72 m3/ha) again for Çatacik (Turkey). In terms of silvicultural quality, the northern provenances were classified as the best ones because of high proportion of trees with straight stems. The largest share of tress with straight stems occurred in the population of Serebryanskoe from Russia (60.8%), while the smallest of Haguenau from France (6.9%). The populations from Southern Europe (Maočnica, Prusačka Rijeka and Çatacik) show poor adaptation to environmental conditions of central Poland.

Opis:
European beech is one of the most important broadleaved tree species in Poland and will play probably even more significant role in the future due to the predicted climate change. The main objectives of this study was to analyse and compare the growth parameters and morphological traits between 23 European beech provenances from south−eastern Poland (fig. 1). The research was conducted on the experimental plot established in Łosie Forest District in 2006. The experiment employed a randomized complete block design consisting of 92 plots (23 provenances×4 blocks). On each plot 100 trees representing given provenance were planted in 1.5×1.5 m spacing. In the spring and autumn 2015 we measured and determined the following parameters for the subsample of 36 trees on each plot: survival rate, tree height, diameter at breast height, diameter of the branch at the middle height of the crown length, stem straightness, crown shape, tendency to create forks, mean angle between stem and branches and spring phenology. We also included different eco−physiographical characteristics for each provenances (tab. 1). We performed basic statistics to describe mean values and standard errors (fig. 2, tab. 2) and finally we quantified the interaction between traits and eco−physiographical characteristics by Principal Component Analysis (PCA) (fig 3, tab. 3). The obtained results indicates that under growth conditions on experimental trial in Łosie Forest District, the provenances from lower elevated regions with lower precipitation and higher mean temperature (i.e. more arid conditions; Kielce and Narol provenances) were characterized by thicker dbh and branch dimeters in contrast to regions from southern Poland (Łosie, Bricza 1, Stary Sącz and Nawojowa). European beech provenances from regions with more humid conditions and lower mean annual temperature, as well as shorter vegetation season are characterized by higher survival rate. They are also higher than other provenances, but reveal the lower ratio dbh to branch diameter.

Opis:
Mechanical site preparation (MSP) is commonly used to enable forest regeneration of clear-cuts. Less intense methods may be more suitable from an environmental point of view, but such a method can result in the lack of natural regeneration. We compare the influence of three MSP methods on natural regeneration of Scots pine. The methods differ in their degree of soil disturbance. The effects of MSP by forest plough (FP), active plough (AP), and forest cutter (FC) on density, quality, and biometric parameters of one-year old seedlings were determined. The highest density of seedlings was obtained in the FP treatment (188,000 seedlings ha–1). The seedling density was significantly lower in the AP method (121,000 seedlings ha–1), and in the FC variant (36,000 seedlings ha–1). The best quality seedlings were found in the FC variant, and the worst – in the FP treatment. Most biometric parameters of seedlings did not differ by MSP method, except for the root length and root:shoot ratio. By the end of growing season, in the FP treatment, 1-year old seedlings formed a top bud more than twice as often as the seedlings from the AP and FC treatments. The FP method led to the best Scots pine natural regeneration. The results obtained in the FC variant were not as good as in the FP method, though they were still acceptable from the silvicultural point of view. The FC method was the least intensive method of site preparation, yet it is considered the most appropriate from the environmental (soil protection) point of view.

Opis:
This paper presents the genetic variability in the growth parameters and morphological traits, as well as the silvicultural quality of progeny of 23 European beech (Fagus sylvatica L.) provenances from south−eastern Poland. The research was conducted on the experimental plot established in the Łosie Forest District in spring 2006. After 10 years, during the spring and autumn, we determined and measured the spring phenology and survival rate, the diameter at breast height (dbh), the tree height, and the straightness of trunk. The results obtained point out the considerable variability of analysed features, both within and between different beech populations (tab.). Highest and lowest survival rates are noted for the beeches from Lutowiska and Leżajsk (populations 451 and 461), respectively (fig. 2). Lowest mean height and dbh were achieved by beeches from Bircza (453), while the tallest and broadest trees were from the Kielce population (390) (fig. 3−4). The overall silvicultural assessment based on survival, height, dbh, spring phenological phases and straightness of the trunk revealed that the most valuable populations of beech are those originating from Kielce (390), Bircza (454), Strzyżów (459), Lesko (452), Rymanów (457) and Lutowiska (451). In turn, the analysis resulted in least favourable assessments for beeches from Bircza (453) and Gromnik (362). Thus, we confirmed also that trees of local origin are not always best−adapted to (and do not always grow best in) the place they originate from. The obtained results are highly relevant from the principles of creating the seed source regions for beech in Poland, as the proper selection of a population for the given place of growth may yield benefits for forest ecology and management.

Opis:
In this paper we report preliminary results of optical studies on Y$\text{}_{3}$Al$\text{}_{5}$O$\text{}_{12}$ (YAG) crystals codoped with Ce and Mg. By using measurements of luminescence, absorption, and luminescence excitation spectra we demonstrate that although the basic features introduced to the YAG host by the Ce-doping remain intact, the Mg-codoping imposes some significant changes on other properties of the material. These changes are potentially important for laser and/or scintillator applications of YAG:Ce and are due, most likely, to modifications of defect populations in the material. We characterize them by using the techniques of thermoluminescence and excited state absorption under excimer laser pumping. These techniques, interestingly, yield results that seem inconsistent. While the thermoluminescence signal of the Mg-doped sample is strongly reduced, suggesting that trap concentrations in the presence of Mg are suppressed, the excited state absorption signal, which we also relate to the traps, is higher. We offer a tentative explanation of this contradiction between the two experiments that involves a massive transfer of electrons from the Mg-related defects to the excited state absorption centers caused by the excimer pump itself.

Opis:
Przedmiotem pracy jest ujawnienie i charakteryzacja realnej struktury nowych typów scyntylacyjnych monokryształów mieszanych granatów lutetowo-itrowo-glinowych (LuxY1-x)3Al5O12 (LuYAG) aktywowanych prazeodymem oraz niedomieszkowanych. Badania wykonano przy użyciu konwencjonalnego źródła promieniowania rentgenowskiego metodą rentgenowskiej topografii dwukrystalicznej oraz za pomocą dyfraktometrii wysokorozdzielczej. Wykonano również badania polaryskopowe. Na wybranych próbkach przeprowadzono badanie jednorodności składu chemicznego za pomocą skaningowego mikroskopu elektronowego z przystawką do spektroskopii z dyspersją energii (EDX). Topogramy rentgenowskie przebadanych próbek wskazują na dobrą jakość strukturalną badanych monokryształów. Pewnym problemem strukturalnym zaobserwowanym na wykonanych topogramach dwukrystalicznych są naprężenia sieci, których pierwotną przyczyną są efekty segregacyjne i różne obszary ściankowane.
The present paper concerns revealing and detailed characterization of the real structure of the new scintillator crystals of mixed lutetium-yttrium-aluminum garnets (LuxY1-x)3Al5O12 (LuYAG) , either undoped or activated by praseodymium. The characterization of the crystals has been performed by means of the following methods, using conventional X-ray sources: double crystal topography and high resolution diffractometry. Polariscopic investigations have also been performed. Moreover, selected samples have been studied by scanning electron microscopy with energy dispersive X-ray spectrometer (EDX) attachment, among others to investigate their chemical homogeneity. The topographs of the analyzed samples indicate a good crystallographic quality of the crystals. Some crystallographic imperfections include residual strains, primarily caused by dopant and chemical composition segregation as well as some facetted regions.

Opis:
An assessment of the current dynamic status of tree species occurring in the Strict Reserve of the Białowieża National Park is presented. On the basis of long−term trends and analysis of large−scale inventory data, the three major groups of trees are distinguished: 1) ‘safe’ group, containing hornbeam and lime, 2) ‘presently safe, but declining in a long−term run’ group, involving spruce, birch and alder, and 3) ‘threatened and highly threatened’ group, consisting of oak, pine, ash, maple, elm and aspen.
