Opis:
Whether exercise will have a beneficial impact on health depends on proper selection of the intensity and character of physical effort. A well-planned program will improve the functioning of some organs and systems as a result of adaptative changes in the organism. For the adaptation to occur, however, training stimuli must reach a threshold value. This means that the intensity of training should match the participants' abilities. According to the principle of progression, one should adapt the volume, the difficulty and intensity of exercises to the requirements of the participants, which will be increasing with time. The ability of drawing up a safe and effective program consists of putting the components of training together, both in single classes and long-term plans for shaping the participants' physical fitness. This paper presents a selection of all the components of recreation training for Step Reebok recreation classes.

Opis:
Aberrant expression of sialic acids or altered linkage types is closely associated with malignant phenotype and metastatic potential, and can have prognostic significance in human cancer. The present study was undertaken to evaluate whether expression of sialylated derivatives on melanoma cell surface is associated with tumour progression. Four cell lines (WM1552C, WM115, IGR-39 and WM266-4) were used in the study. Cell surface expression of sialic acids was evaluated by flow cytometry with the use of Maackia amurensis and Sambucus nigra lectins. Moreover, adhesion and migration potential of melanoma cells and involvement of sialic acids in these processes were analysed. We have demonstrated that WM266-4 cells have a significantly higher level of α2,3-linked sialic acid residues than other cells, whereas IGR-39 cells had lower expression of α2,6-linked sialic acids. The adhesion efficiencies of WM1552C and WM115 cells were significantly lower than that of IGR-39 and WM266-4 cells. In contrast, WM266-4 cells repaired scratch wounds at least twice as fast as other cells. Melanoma cell adhesion to fibronectin in the presence of Sambucus nigra agglutinin (SNA) was reduced only in IGR-39 and WM266-4 cells, whereas the impact of Maackia amurensis agglutinin (MAA) on this process was much more important. Migration efficiency of melanoma cells was reduced more strongly in the presence of MAA than SNA. In conclusion, our results show that melanoma progression is associated with the increased expression of α2,3-linked sialic acids on the cell surface and these residues could promote melanoma cell interaction with fibronectin.

Opis:
Parity progression ratios (PPR's) have been extensively described in literature on demography and have played an important role in fertility, unlike the idea of calculating projected parity progression ratios proposed by Brass (1985). However, we decided to use this method in our paper to analyse future fertility trends, firstly by assessing age-specific parity progression ratios for women in childbearing ages, and then by comparing these ratios with ratios at the end of women's reproductive life, as well as by comparing the latter with the completed PPR's. More specifically, the aim of this study is to adopt a modified Brass method to calculate the projected parity progression ratios using the age-period fertility data sourced from the Human Fertility Database (HFD). We progress to use the observed and predicted age-specific PPR's to examine parity progressions in Poland as a case study.

Opis:
Slavic equivalents to the English term sustainabilityThe paper examines the issue of how the term sustainable development (sustainability), coined exactly 30 years ago by the United Nations World Commission on Environment and Development, has been reproduced in the Slavic languages. The history of the primary English term’s first use as well as its source have been discussed, with special consideration given to the fact that both English and Slavic terms expressing the concept of sustainability have native components. Using a semasiological approach to the studied terminological units, the author analyzes their outer and inner form of the terms in relation to their meaning (definition). The study emphasizes the semantic progression within the various Slavic words used as terms expressing the contemporary idea of sustainable development. This semantic evolution is observable, among other things, in the component of positive evaluation inherent in the terms’ meanings and definitions. Słowiańskie odpowiedniki terminu sustainabilityArtykuł porusza kwestię sposobów oddawania w językach słowiańskich terminu sustainable development (‘zrównoważony rozwój’), ukutego 30 lat temu przez Światową Komisję ds. Środowiska i Rozwoju Organizacji Narodów Zjednoczonych. Omówiono historię powstania angielskiego terminu i jego źródło, zwracając uwagę szczególnie na to, że zarówno angielski termin sustainability, jak i jego słowiańskie odpowiedniki wywodzą się z rodzimych elementów. Stosując semazjologiczne podejście do badanych jednostek terminologicznych, autorka analizuje ich zewnętrzną i wewnętrzną formę w odniesieniu do ich znaczenia (definicji). W wynikach analizy na pierwszy plan wysuwa się progresja semantyczna ogólnosłowiańskich wyrazów użytych jako terminy na określenie współczesnej idei zrównoważonego rozwoju. Tę semantyczną ewolucję można zaobserwować m.in. w pozytywnym wartościowaniu, które stanowi wewnętrzny komponent znaczenia i definicji terminów.

Opis:
Informed by the developments in autoethnography, narrative analysis and biographical sociology this paper seeks to affirm that understanding our narrative enables self-understanding and more importantly enables the understanding of others. Using an autoethnographic approach this paper explores the rupture in self and family identity following two traumatic events: the onset of a chronic illness (Multiple Sclerosis) and the death of a mother. It is the story of the life of my mother, who suffered with MS for 9 years and the story of my sister and myself, who cared for her throughout our childhood up to her death in 2000. The rupture in identity that we suffered interrupted the world in which we lived and exposed the contents of our individual and collective world(s). The themes that emerged from the narratives in this study suggest rupture is experienced as a movement of transgression that leads to movements of regression and progression.

Opis:
Alzheimer’s disease is the most common form of dementia that can cause a brain neurological disorder with progressive memory loss as a result of brain cell damage. Prevention and treatment of disease is a key challenge in today’s aging society. Accurate diagnosis of Alzheimer’s disease plays an important role in patient management, especially in the early stages of the disease, because awareness of risk allows patients to undergo preventive measures even before irreversible brain damage occurs. Over the years, techniques such as statistical modeling or machine learning algorithms have been used to improve understanding of this condition. The objective of the work is the study of the methods of detection and progression of Alzheimer’s disease through artificial intelligence techniques that have been proposed in the last three years. The methodology used was based on the search, selection, review, and analysis of the state of the art and the most current articles published on the subject. The most representative works were analyzed, which allowed proposing a taxonomic classification of the studied methods and on this basis a possible solution strategy was proposed within the framework of the project developed by the Cuban Center for Neurosciences based on the conditions more convenient in terms of cost and effectiveness and the most current trends based on the use of artificial intelligence techniques.

Opis:
The use of cartographic sources and methods are the basic tools of historical geography. One of the main research trends in this field is the analysis of the spatial layout and number of old settlement units. The confrontation of maps with historical data allows the drawing of a town’s area at a certain time to be studied. The retrogression (R) and progression (P) methods that are currently used are imperfect and the model created (map) is usually incomplete and its reliability is limited. In the author’s opinion, the joining of retrogression and progression (a new method; combined – K)1 increases the quality of cartographic reconstruction of natural and cultural landscapes. The use of basic mathematical methods from the scope of set operations means the component reliability of the researched cartographic model can be varied because the common part of the retrogression and progression cartographic model represents mutual verification of source data. Quantitative effectiveness assessments of retrogression (R), progression (P) and the combined method (K) can be made for countable elements (e.g. buildings). As part of the conducted study, the effectiveness of separate methods was calculated: R = 76% for retrogression, P = 59% for progression and K = R ∪ P = 85% for the combined method. The mutual verification of the methods (R ∩ P) included 45% of residential buildings. The author describes the proposition of a new method and the course of verification research.

The aim of the study was to answer the question whether there are differences in the progression of the disease and its morphology, dependent of the patient’s age, as well as show colorectal cancer differences between young and elderly patients. Material and methods. During the period between 2009 and 2011, 747 patients with rectal carcinoma, and 478 with colon cancer underwent surgery at the Department of General and Colorectal Surgery. The study group comprised patients under the age of 40 years (56 patients) and >80 years (90 patients). The following were subject to analysis: gender, tumor location, percentage of radical and palliative procedures, clinical and histopathological staging, as well the differences in the morphology of the tumor. The χ2 test and Yates’ correction were used for statistical analysis. p<0.05 was considered as statistically significant. Results. A higher incidence of rectal carcinoma was observed in younger patients (p=0.004). Amongst the younger patients 30.3% were diagnosed with stage III cancer, while 35.7% with stage IV. In case of elderly patients 30.6% were diagnosed with stage III cancer, while 30.7% with stage IV. In 53.3% of young patients, local lymph node metastases were observed, while in the elderly 41.8%. No statistically significant difference was observed, considering the total number of lymph nodes metastases. However, in case of stage N2, results were unfavorable for young patients 31.8% vs 17% in case of the elderly. Mucogenic adenocarcinoma incidence was similar in both groups. In case of patients< 40 years we observed a higher incidence of poorly differentiated tumors, as compared to the elderly patients (>80 years). Conclusions. 1. It is necessary to create appropriate prevention programs for young community, and improvement of public awareness in this age group. 2. Colorectal cancer (CRC) in young patients is often recognized in advanced stage. 3. A high percentage of unresectable tumors in group of elderly patients shows that CRC is still diagnosed too late in Poland.

Through our study we have established a potential pattern of analysis over the aspect of poetical language. The theme was determined by the purpose of implementing the particular linguistic model created by N. Stănescu, which we call the nichitastănescu pattern. We exemplified the model by identifying the compositional values and the structures that contribute to the creation of a linguistic frame built to measure the main semantics, through which the poetical language is internalized and aestheticized. We also use a specific poetical construction model based on the triadic analysis pattern proposed by the French semiotics group entitled Groupe  μ, in their collective work Rhétorique de la poésie: lecture linéaire, lecture tabulaire, published in 1977.                The value of this study consists in a detailed view over the textual dimensions of expressiveness and significations in the poetical language used by Nichita Stănescu. Throughout his lyrics, the named poet reveals the uniqueness of his specific poetical language in contrast with other Romanian poets.

Opis:
The amount of tax-free personal allowance is one of the most significant parameters of income tax system in Poland. It has been equal PLN 3,089 unchanged since 2008 until 2016. The Constitutional Tribunal predicated that the regulation of the act on PIT specifying the amount of personal allowance violates the article 2 and the article 84 of the Constitution of the Republic of Poland as regards the lack of facility to provide a mechanism adjusting the amount of tax reduction, that would guarantee at least the minimum subsistence. At present its level is specified at the level of more than twofold personal allowance. Therefore, the tax system must be amended. This paper aims at a statistical comparative analysis of gains and losses expected for budgets of both taxpayers and government under prospective various tax systems scenarios. The statistical analysis considers fundamental characteristics of a tax system, i.e. average and marginal tax rates, and tax progression.
Jednym z ważniejszych parametrów systemu podatku dochodowego jest kwota wolna od podatku, która od 2008 r. do 2016 r. w Polsce nie uległa zmianie i wynosiła 3089 złotych. Trybunał Konstytucyjny orzekł, że przepis ustawy o PIT wskazujący wysokość kwoty wolnej od podatku w zakresie, w jakim nie przewiduje mechanizmu korygowania kwoty zmniejszającej podatek, gwarantującego co najmniej minimum egzystencji, jest niezgodny z art. 2 i art. 84 Konstytucji Rzeczypospolitej Polskiej. Obecnie prawo określa minimum egzystencji na poziomie ponad dwukrotnie wyższym od obowiązującej kwoty wolnej od podatku. Konieczna jest zatem korekta systemu podatku dochodowego. Celem artykułu jest przeprowadzenie statystycznej analizy porównawczej strat i zysków zarówno dla budżetu podatników, jak i budżetu państwa, przy różnych scenariuszach proponowanego systemu podatkowego. W analizie statystycznej uwzględnione zostały podstawowe charakterystyki systemu podatkowego, jakiem jest średnia i krańcowa stopa podatkowa oraz progresja. Porównania natomiast dotyczą nowo proponowanych rozwiązań zmian w zakresie kwoty wolnej od podatku.

Opis:
Multiple and diverse cell adhesion molecules take part in intercellular and cell-extracellular matrix interactions of cancer. Cancer progression is a multi-step process in which some adhesion molecules play a pivotal role in the development of recurrent, invasive, and distant metastasis. A growing body of evidence indicates that alterations in the adhesion properties of neoplastic cells play a pivotal role in the development and progression of cancer. Loss of intercellular adhesion and the desquamation of cells from the underlying lamina propria allows malignant cells to escape from their site of origin, degrade the extracellular matrix, acquire a more motile and invasion phenotype, and finally, invade and metastasize. In addition to participating in tumor invasiveness and metastasis, adhesion molecules regulate or significantly contribute to a variety of functions including signal transduction, cell growth, differentiation, site-specific gene expression, morphogenesis, immunologic function, cell motility, wound healing, and inflammation. Cell adhesion molecule (CAM), a diverse system of transmembrane glycoproteins has been identified that mediates the cell-cell and cell-extracellular matrix adhesion and also serves as the receptor for different kinds of virus. We summarize recent progress regarding the role of CAM, particularly, immunoglobulin-CAMs and cadherins in the progression of cancer and discuss the potential application of CAMs in the development of cancer therapy mainly on urogenital cancer.

Opis:
This work is intended as an attempt to illustrate and compare the pattern of fertility in European countries: Belarus, Croatia, Hungary, Poland, Portugal, Spain, Sweden, and Switzerland. It deals with the analysis of fertility trends, with an emphasis on birth by parity. Using data from the Human Fertility Database (HFD) from the year 2016, it has considered the parameters of parity progression ratios (PPR), projected parity progression ratios (PPPR), age‑specific fertility rates (ASFR), age‑order specific fertility rates (AOSFR), and cumulated order‑specific fertility rates accordingly analysed. We have applied indicators known as the projected parity progression ratios to estimate trends of fertility. These offer a more detailed view of the family formation process than the traditional total fertility rate (TFR).
Analiza płodności jest w demografii tematem, który przyciąga uwagę wielu badaczy. Demografowie opracowali wiele różnych metod pomiaru tego zjawiska. Większość badań wykorzystuje tradycyjne miary. Nie dają one jednak szczegółowych informacji na temat tego, jak dokładnie zmienia się płodność w zależności od kolejności urodzenia. Głównym celem jest zbadanie tempa i wzorca płodności oraz zróżnicowania postępów w zakresie kolejności urodzeń w wybranych krajach europejskich. Metoda zapoczątkowana przez Brassa pozwala oszacować progresywne współczynniki kolejności urodzeń. W badaniu tym dokonujemy porównań między obserwowanymi i przewidywanymi współczynnikami. Wyniki pokazują, że metoda prognozowanych współczynników kolejności urodzeń daje stosunkowo dobre dopasowanie i jest przydatna do przewidywania przyszłych trendów płodności. Spadek dzietności w rozważanych krajach europejskich jest spowodowany późnymi decyzjami kobiet o posiadaniu pierwszego dziecka oraz ich tendencją do rodzenia mniejszej liczby dzieci.
