Opis:
Professional and family roles are one of the basic and most important roles performed by adults. Transformations of modern organisations and families show that these two types of social groups are closely related. Work allows people to acquire material resources that are necessary to meet family needs and determine its social status. This study is of qualitative nature. Its main goal is to identify the factors that limit professional activation of mothers and those that limit implementation of the right of fathers to engage in the family life related to the difficulties encountered in reconciling professional and family roles. The attempt to identify these factors was carried out at the level of individual parent strategies, organisation practices, and at the level of implemented social policy, taking into account employers' organisations and trade union opinions.

Opis:
Presented article analyzes the sources of conflict between the family role and the professional role. The article is focused on the sources of conflict between work and family. The possibility of interference between these two roles should be closely investigated and better understood. Despite that in some cases the lines between professional and family life tend to blur, both of these types of life still have different roles and requirements. The article is an investigation of attainable literature and studies regarding the subject. The empirical investigation imply that the conflict of roles starts when the time committed to the requirements of one of them makes it difficult to meet the requirements of the other. Even though lately the number of investigations of this subject has grown, the results are still differentiated and sometimes even self-contradictory. The comparison of the results of different investigators showed that the work-family and family-work conflicts are positively correlated which indicates mutual strengthening and necessity of searching for common and individual causes that condition their coexistence, domination and strength. The received results are consistent with the results of many other studies, whose authors tried to indicate that each of these conflicts could have specific causes and course.

Opis:
The article presents the employee motivation phenomenon. Thanks to the use of literature review methods, theoretical aspects of the issue were discussed and possible models of motivation, financial and non-financial elements of motivation were presented. The article constitutes the synthesis of employee motivation theory and includes the explanation of how motivation affects employee behavior. The aim of this study is to present motivational models, because the motivation of employees is a difficult and demanding task for employers and managers. Enterprises are focused on multiplying profits, development and maintenance of competitive positions on the market, thus it is necessary to properly motivate and search for new solutions covering financial and non-financial incentives. Considering high costs of retention of the employee in the organization, it is rational to identify, analyze and criticize the theories of motivation underlying the retention of employees in organizations. Low level of unemployment can force many organizations to re-examine their employees' retention strategies as part of their efforts.

Opis:
The aim of the study was to develop a low-cost method for tourism opportunity spectrum evaluation in rural landscapes. The method uses the geographic information system (GIS) for spatial analysis of the problem. Open source materials are used in the evaluation. Three principal indices derived from spatial data are evaluated: attraction index, view index, and access index. These form the basis for tourism suitability and opportunity spectrum evaluation. The analysis is realized for two types of tourists: those using cars, and hikers. The method permits the current state of tourism to be identified, and points out possible ways for further development as well as identifying valuable but overexploited zones which should be conserved. The obtained results can improve the sustainable management of landscapes and enhance the profits of rural areas.

Opis:
Jednym z ważnych obszarów zastosowania satelitarnych obserwacji Ziemi jest statystyka rolnictwa. Wykorzystanie nowych technologii cyfrowych i danych satelitarnych przyczyniło się do jej unowocześnienia i pomaga rozwiązywać problemy, z jakimi mierzy się ona obecnie oraz z jakimi borykają się odbiorcy danych statystycznych z zakresu rolnictwa. Głównym celem niniejszego artykułu jest zaprezentowanie innowacyjnego systemu satelitarnej identyfikacji i monitorowania upraw rolnych – SATMIROL. System ten został opracowany przez Główny Urząd Statystyczny, Instytut Geodezji i Kartografii oraz Centrum Badań Kosmicznych Polskiej Akademii Nauk na potrzeby statystyki rolnictwa z wykorzystaniem danych satelitarnych z programu Copernicus i danych administracyjnych. W opracowaniu omówiono wybrane moduły tego systemu, w których metody teledetekcji satelitarnej znalazły zastosowanie do rozpoznawania upraw. Przedstawiono też wyniki szacunku powierzchni upraw w skali kraju w trzech okresach pomiarowych w latach: 2019, 2020 i 2021. Wprowadzenie systemu SATMIROL umożliwiło prezentację danych w ujęciu przestrzennym, na co nie pozwalają tradycyjne metody stosowane w produkcji statystycznej. Dzięki nowej metodzie dane mogą być przedstawiane na wszystkich poziomach podziału administracyjnego kraju (województw, powiatów i gmin).
One important area where satellite-based Earth observation is applied in is agricultural statistics. The use of new digital technologies and satellite data have contributed to the modernisation of the aforementioned scientific area and is designed to overcome the problems that both agricultural statistics and the recipients of statistical data are faced with. The main aim of the article is to present an innovative system of satellite-based crop identification and crop growth monitoring – SATMIROL. The system was developed by Statistics Poland, the Institute of Geodesy and Cartography and the Space Research Centre of the Polish Academy of Sciences. SATMIROL provides agricultural statistics based on satellite data from the Copernicus programme and administrative data. The article focuses on selected modules of the system which involve the use of satellite remote sensing for crop identification. The study also presents a nationwide crop area estimation performed in three periods: 2019, 2020 and 2021. The implementation of SATMIROL allowed the presentation of statistical data on agriculture in spatial terms, which is not possible when applying traditional methods of data production. This new method of acquiring data enables their presentation at all levels of Poland’s administrative division, i.e. by voivodship, poviat (district) and gmina (commune).

Opis:
The oligomeric metalloenzymes protein phosphatases dephosphorylate OH groups of Ser/Thr or Tyr residues of proteins whose actions depend on the phosphorus signal. The catalytic units of Ser/Thr protein phosphatases 1, 2A and 2B (PP1c, PP2Ac and PP2Bc, respectively), which exhibit about 45% sequence similarity, have their active centers practically identical. This feature strongly suggests that the unknown structure of PP2Ac could be successfully homology-modeled from the known structures of PP1c and/or PP2Bc. Initially, a theoretical model of PP1c was built, including a phosphate and a metal dication in its catalytic site. The latter was modeled, together with a structural hydroxyl anion, as a triangular pseudo-molecule (Zno or Mno), composed of two metal cations (double Zn2+ or Mn2+, respectively) and the OH- group. To the free PP1c two inhibitor sequences R29RRRPpTPAMLFR40 of DARPP-32 and R30RRRPpTPATLVLT42 of Inhibitor-1, and two putative substrate sequences LRRApSVA and QRRQRKpRRTI were subsequently docked. In the next step, a free PP2Ac model was built via homology re-modeling of the PP1c template and the same four sequences were docked to it. Thus, together, 20 starting model complexes were built, allowing for combination of the Zno and Mno pseudo-molecules, free enzymes and the peptide ligands docked in the catalytic sites of PP1c and PP2Ac. All models were subsequently subjected to 250-300 ps molecular dynamics using the AMBER 5.0 program. The equilibrated trajectories of the final 50 ps were taken for further analyses. The theoretical models of PP1c complexes, irrespective of the dication type, exhibited increased mobilities in the following residue ranges: 195-200, 273-278, 287-209 for the inhibitor sequences and 21-25, 194-200, 222-227, 261, 299-302 for the substrate sequences. Paradoxically, the analogous PP2Ac models appeared much more stable in similar simulations, since only their "prosegment" residues 6-10 and 14-18 exhibited an increased mobility in the inhibitor complexes while no areas of increased mobility were found in the substrate complexes. Another general observation was that the complexes with Mn dications were more stable than those with Zn dications for both PP1c and PP2Ac units.

Opis:
In this article, we present the work carried out in our group on various fields of theoretical biochemistry. Our main fields of research are as follows: i) design of an algorithm for de novo prediction of protein structure from amino-acid sequence using energetic criteria, ii) theoretical modeling of the structure and dynamics of neurohypophyseal-hormone receptors, iii) quantum-mechanical investigation of reactions in organic chemistry and biochemistry, and iv) theoretical conformational analysis of small peptides using experimental information. The performance of different machines, depending on the kind of calculations with special focus on the exploitation of parallelism as well as the applicability and performance of various commercial, free, and our home- made software (AMBER. GAUSSIAN, ECEPPAK, GAMESS, SYBYE, MSI/Biosym) available at TASK and the importance of graphical processing of the data are discussed.

Opis:
The effects of inhibitors of plasma membrane NADPH oxidase on menadione-induced cell injury processes were studied using human osteosarcoma 143B cells. The intracellular level of superoxide in the cells treated with menadione for 6 h reached a maximum followed by an abrupt decrease. The population of apoptotic cells detected by Annexin V and propidium iodide double staining also reached its maximum at 6 h of menadione-treatment while that of necrotic cells increased continuously reaching 90% of the total population at 9 h of the treatment. Pretreatment of the cells with inhibitors of NADPH oxidase, including diphenyliodonium chloride, apocynin, N-vanillylnonanamide and staurosporine was effective in lowering the menadione-induced elevations of superoxide, and also in the suppression of the switch of the cell death mode from apoptosis to necrosis in menadione-treated cells except for the case of staurosporine. These results strongly suggest that superoxide generated by NADPH oxidase, besides that generated by the mitochondria, may contribute to the remarkable increase in the intracellular level of superoxide in the cells treated with menadione for 6 h resulting in the switch from apoptosis to necrosis, although a direct evidence of the presence of active and inactive forms of NADPH oxidase in control and menadione-treated 143B cells is lacking at present.
