Synchronization and Spin-Flop Transitions for a Mean-Field XY Model in Random Field
No full textWe characterize the phase space for the infinite volume limit of a ferromagnetic mean-field XY model in a random field pointing in one direction with two symmetric values. We determine the stationary solutions and detect possible phase transitions in the interaction strength for fixed random field intensity. We show that at low temperature magnetic ordering appears perpendicularly to the field. The latter situation corresponds to a spin-flop transition

SUMMARY
Introduction. The problem of growing incidence of bad posture in children and adolescents is so significant that it has become an important social problem. One of reasons behind higher incidence of abnormal posture may be underweight, overweight or obesity. Objectives. Evaluation of incidence of bad posture in boys aged 7-15, including the Body Mass Index (BMI). Material and methods. The study included 511 boys aged 7-15 from Szczecin. Each age group consisted of approx. 50-70 children. Posture was assessed with the spherosomatometric method. Physiological curvature of the spine in the sagittal plane were determined. Next, normative values for anterior-posterior spinal curvatures were used to determine the incidence of bad posture. Based on logistic regression, the parameters of the logit model were assessed, taking into account subjects’ age and BMI. Results. In the entire population, bad posture was identified in 32.48% of subjects. Age did not differentiate the incidence of bad posture in terms of statistical significance. Boys with incorrect BMI amounted to 28.37% of all subjects. Underweight was observed in 6.96% of subjects. 7.54% of subjects were overweight and 2.03% obese, which gave a total of 9.57% of the researched population. The increase in BMI correlated with higher chances of bad posture by almost 25%, while age was a variable which reduced the risk of bad posture by almost 15%. Conclusions. Incorrect BMI predisposed subjects to bad posture. High proportion of children with bad posture justify the need to promote preventive and corrective measures. The increasing proportion of overweight and obese children should serve as a motivator to shape healthy behaviors of students and parents, as well as schools and the medical environment.

Doping and supplementation applied in Bydgoszcz gyms
Streszczenie
Celem pracy jest określenie jakich środków dopingujących oraz jakich suplementów diety używają osoby ćwiczące na siłowniach w Bydgoszczy.
Badania zostały przeprowadzone wśród osób trenujących na siłowniach w Bydgoszczy. Metodą, która została zastosowana był sondaż diagnostyczny.
Na podstawie badań można stwierdzić, że sterydy anaboliczno-androgenne są najczęściej stosowanym środkiem dopingującym. Badania wykazały również, że znaczna część badanych stosuje kreatynę w celu poprawienia wyglądu sylwetki, co wpływa na jakość ich treningów. Prawie wszyscy ankietowani natomiast twierdzą, że suplementacja jest zjawiskiem powszechnie występującym.
Słowa kluczowe: doping, suplementy, siłownia, Bydgoszcz.
Abstract
The aim of the study is to determine what kind of doping and what kind of supplements are in use by those exercising in gyms in Bydgoszcz.
The study was conducted among people practicing in gyms in Bydgoszcz. Method that was used was a diagnostic survey.
Based on research it can be concluded that the anabolic androgenic steroids are the most commonly used doping. It can be also conclude that a significant proportion of respondents is using creatine to improve the appearance of the figure, which affects the quality of training. Almost all respondents claim that supplementation is a phenomenon commonly occured.

SUMMARY
Introduction. Swimming as a sport encompasses various styles and distances (from 50 up to 1,500 meters). The correlation between sports results and general/special muscle strength seems unquestionable. Aim. The purpose of this paper is to answer the question related to maintaining the proportion between muscle strength development (which depends mainly on land-based trainings) and endurance trainings in water. Material and methods. The study covered 14 leading swimmers from MKP Szczecin who specialized mainly in short and medium distances; they were members of the national senior and junior teams in the 2013/14 training year. The general strength tests were conducted at the beginning and at the end of the winter and summer preparatory periods. The following tests were performed: bench-pressing, pull-ups and bar dips. At the end of the main research period, a thrust test was conducted on land (on a swim bench), as well as a thrust test in the water. Results. All participants demonstrated progress in results between the summer season and the winter season. The range of training loads was higher in the summer due to the length of preparation (by about 100%). The individual progress was, however, very varied. Conclusions. The level of sports progress achieved by individual swimmers was greatly diversified. The relatively high level of general and special strength in the tested swimmers was linked to their need to display these motor skills while swimming. Subjects who showed the greatest progress in the general and special strength trials, displayed the biggest improvement in their swimming performance during the competition season. Swimmers with a fairly high level of strength, but a moderate sports level should analyze and improve their swimming technique. Subjects whose progress in general and special strength tests was the least significant, should try and achieve progress by developing other technical and coordination skills.

Modelowanie czasu trwania zdarzeń powtarzających się na przykładzie zmian miejsca zatrudnienia
No full textThis paper concerns the issue of survival modelling in the case of repeated events. In the modelling of this type of events, attention should be paid to the existence of dependence among the analysed durations, as well as the occurrence of unobserved heterogeneity. One of the ways to include these aspects in the analysis is to use models with random effects. The primary objective of this paper is to present the application of such models to analyse changes in the place of employment. The duration of individual periods of employment for the surveyed employees was modelled. The approach used made it possible to identify factors influencing decisions on job changes, but also to assess the risk of occurrence of events such as termination of employment, and to examine the impact of unobserved heterogeneity on the results of the estimations.W artykule został podjęty problem modelowania czasu trwania w przypadku powtarzających się zdarzeń. W modelowaniu tego typu zdarzeń należy zwrócić uwagę na występowanie zależności między analizowanymi czasami trwania, jak również nieobserwowalnej heterogeniczności. Jednym ze sposobów uwzględnienia w analizie tych aspektów jest wykorzystanie modeli z efektami losowymi. Głównym celem artykułu jest zaprezentowanie możliwości wykorzystania tego typu modeli do analizy zmian miejsc zatrudnienia. Modelowaniu poddano czas trwania poszczególnych okresów zatrudnienia dla badanych jednostek. Wykorzystane podejście umożliwiło identyfikację czynników wpływających na decyzje o zmianie miejsca zatrudnienia, ocenę ryzyka wystąpienia zdarzenia, jakim jest rozwiązanie stosunku pracy, oraz zbadanie wpływu nieobserwowalnej heterogeniczności na wyniki przeprowadzonych estymacji.This study has been prepared as part of a project funded by the National Science Centre, Poland, entitled “The modeling of parallel family and occupational careers with Bayesian methods” (2015/17/B/HS4/02064)

Streszczenie
Celem badań było określenie stopnia i charakteru zagrożeń występujących w strefie oznakowania pływalni krytych odnoszących się do wymaganych zasad bezpieczeństwa. Badania przeprowadzono na 29 obiektach, zlokalizowanych na terenie dziesięciu województw. Posłużono się metodą jakościowych badań terenowych oraz metodą badań niereaktywnych. Stwierdzono, iż w ponad połowie badanych pływalni krytych (51,7%) znak zakazu A-8 „skakanie do wody zabronione” miał formę graficzną niezgodną z obowiązującymi przepisami. Znaki informacyjne: C-2 – „niebezpieczna głębokość wody” i C-3 – „nagły uskok” wystąpiły tylko w 27,6% badanych obiektów. W zakresie znaków pozaprawnych – komunikatorów stwierdzono, że nie istnieje ujednolicony sposób przekazywania informacji. Używana symbolika jest bardzo różnorodna, co powoduje chaos w postaci różnych oznakowań. W celu zwiększenia bezpieczeństwa osób korzystających z pływalni krytych należałoby podjąć działania zmierzające do opracowania i wprowadzenia ujednoliconych wzorów oznaczeń, co stanowi konieczny warunek pełnego uczestnictwa we współczesnej kulturze fizycznej.

Abstract
The aim of the research was to determine the level and nature of risks occurring in the sign zone of indoor pools relating to required safety rules. The research was conducted at 29 facilities located in ten provinces. The method of qualitative field research was applied. It was found that at more than half of the examined indoor pools (51.7%) the A-8 prohibitory sign “jumping into water is prohibited” had the graphic form that was inconsistent with the binding provisions. The information signs: C-2 – “dangerous depth of water” and C-3 – “sudden drop” occurred only at 27.6% of examined facilities. Within the scope of non-legal signs – communicators it was found that there is no uniform manner of providing information. The symbols used is very diverse which causes chaos in the form of various markings. In order to improve the safety of persons using the indoor pools, activities aiming at developing and introducing uniform models of markings should be undertaken, which constitutes a necessary condition of full participation in modern physical culture.
