Algorithmic Trading and Efficiency of the Stock Market in Poland

The aim of the article is to investigate the impact of algorithmic trading on the returns obtained in the context of market efficiency theory. The research hypothesis is that algorithmic trading can contribute to a better rate of return than when using passive investment strategies. Technological progress can be observed in many different aspects of our lives, including investing in capital markets where we can see changes resulting from the spread of new technologies.The methodology used in this paper consists in confronting a sample trading system based on classical technical analysis tools with a control strategy consisting in buying securities at the beginning of the test period and holding them until the end of this period.The results obtained confirm the validity of the theory of information efficiency of the capital market, as the active investment strategy based on algorithmic trading did not yield better results than the control strategy

Proceedings physiotherapy in complications of diabetes

Cukrzyca jest narastającym problemem XXI wieku. Przewlekła hiperglikemia stanowi przyczynę wielu zmian patologicznych w postaci mikro- i makroangiopatii, neuropatii oraz zespołu stopy cukrzycowej i w ostateczności — amputacji. Opieka nad chorym rozpoczyna się w momencie rozpoznania cukrzycy. Oznacza to, że już na początku postępowania należy wdrożyć program nadzoru medycznego, psychologicznego, a także fizjoterapeutycznego w celu zwrócenia uwagi na edukację, naukę samokontroli, zmianę stylu życia i nawyków żywieniowych oraz zwiększenie aktywności fizycznej pacjenta.Diabetes is an increasing problem in 21st century. Chronic hyperglycemia leads to micro and macriangiopathy including peripheral nerve damage and diabetic foot syndrome which may result in amputation. Care of the patient with diabetes starts at diagnosis and already then system of patient’s surveillance should be introduced. Special attention needs to be paid to psychological and physiotherapeutic aspects of care in order to stress importance of education and patient’s self-control as well as the need of behavioral changes (exercise and medical nutrition therapy)

Comprehensive scope of physiotherapy in the prevention and treatment of patients with diabetes

Cukrzycę uważa się za epidemię XXI wieku. W celu zmniejszenia  liczby powikłań u chorych na cukrzycę należy  do procesu leczenia  a także profilaktyki dołączyć fizjoterapię. Odpowiednio dobrany  wysiłek fizyczny,  zabiegi fizykoterapeutyczne oraz masaż pozytywnie wpływają na kontrolę masy ciała, zwiększenie wrażliwości na insulinę, polepszenie jakości życia a także zmniejszenie zachorowań na choroby sercowo-naczyniowe. Kompleksowa ocena kliniczna pacjenta pozwoli ustalić optymalny program fizjoterapii, który powinien być indywidualnie dobrany pod kątem rodzaju, częstotliwości, czasu trwania oraz intensywności aktywności fizycznej.  Diabetes is considered to be an epidemic of the 21st century. Physiotherapy should be included, in both treatment plan and prevention of chronic complications in patients with diabetes. Properly selected individualised exercise, physical therapy and massage have a positive impact on weight control, increase insulin sensitivity, improve the quality of life and decrease the morbidity of cardiovascular disease. Comprehensive clinical evaluation of the patient allows determination of the optimal physiotherapy program, which should be planned  according to the type, frequency, duration and intensity of physical activity.

Body balance in people practicing snowboarding

While snowboarding, the human body is subjected to many forces and factors affecting balance. It is assumed that practising snowboarding may improve balance, but the evidence from the literature is scarce. Therefore, our study aimed to examine the effect of snowboard training on balance parameters in adults. Methods: The study included 34 subjects between 19 to 26 years old (21.4 ± 1.44) – students of the University School of Physical Education in Wrocław. They were divided into 2 equal groups. The first group, the practising group consisted of 17 snowboarders who participated in a 6-day snowboard training. The second group, the control group consisted of 17 individuals who had never practised snowboarding. For the conduct of the study, a FreeMED force plate was used. The following parameters were measured: the length of COP sways, the surface of the COP ellipse, and COP ellipse angle. Tests were performed with eyes closed and open. Results: Values of most of the parameters in the practising group decreased insignificantly after 6-day training. Values of parameters in the control group were in most cases insignificantly higher in comparison with the practising group. Conclusions: Our findings may suggest that snowboard training has no effect on balance. Further research on larger groups of participants is required. Research methodology should include electromyography, measurement of the moment of muscle force, and kinematic analysis for evaluation movement during real snowboard ride

The Resilient Smart City Model–Proposal for Polish Cities

The smart city (SC) concept is currently one of the leading ideas in the field of management. It has also become important for Polish cities in terms of sustainable development. Therefore, it is important to determine the priority in urban development; and the areas that need investment to make cities smart. Based on the literature review, it can be stated that there are many available concepts of SCs since the level of development of many cities in the world is different and the priorities of the developed areas vary. The identified SC management models present common parts, resulting from the defining basis, as well as additional aspects important for an SC, stemming from their specificity and the approach of their managers. Thus, the aim of the article is to propose the author’s model of resilient smart city development in Poland. To achieve the objective, a systematic literature review was applied, and the analysis of existing SC management models in the world was carried out in order to identify these models components and documents profiling SC strategies. These areas should be the focus of managers when creating city development strategies in Poland

The risk of a blood pressure increase during treatment with selected psychotropic drugs

Arterial hypertension is the most common cardiovascular risk factor in the general population. Increased mortality from arterial hypertension affects all ethnicities and ages, including those with mental disorders. Most people with arterial hypertension suffer from the primary form of the disease. The aim of this article was to analyze the influence of psychiatric drugs on blood pressure. The articles for analysis were selected via the PubMed search engine in the Medline database using the names of individual drugs or a group of psychotropic drugs, the AND operator and the words "hypertension" or "blood pressure" or "cardiovascular system". The articles were then selected and 36 references were selected for analysis. Selected articles were archived on December 24, 2020. Many medications with the potential to increase blood pressure are used to treat mental illness. These include venlafaxine, milnacipran, bupropion, esketamine, 1st and 2nd generation antipsychotics, tricyclic antidepressants and psychostimulants. In patients using psychotropic drugs that may increase blood pressure, attention should be paid to monitoring it during treatment

Community-level physiological profiles of microorganisms inhabiting soil contaminated with heavy metals

The aim of the study was to assess the diffe-rences in the bacterial community physiological profiles in soils contaminated with heavy metals versus soils without metal contaminations. The study’s contaminated soil originated from the surrounding area of the Szopienice non-ferrous metal smelter (Silesia Region, Poland). The control was soil unexposed to heavy metals. Metal concentration was appraised by flame atomic absorption spectrometry, whereas the the community-level physiological profi le was determined with the Biolog EcoPlatesTM system. The soil microbiological activity in both sites was also assessed via dehydrogenase activity. The mean concentrations of metals (Cd and Zn) in contaminated soil samples were in a range from 147.27 to 12265.42 mg kg-1, and the heavy metal contamination brought about a situation where dehydrogenase activity inhibition was observed mostly in the soil surface layers. Our results demonstrated that there is diversity in the physiological profi les of microorganisms inhabiting contaminated and colntrol soils; therefore, for assessment purposes, these were treated as two clusters. Cluster I included colntrol soil samples in which microbial communities utilised most of the available substrates. Cluster II incorporated contaminated soil samples in which a smaller number of the tested substrates was utilised by the contained microorganisms. The physiological profi les of microorganisms inhabiting the contaminated and the colntrol soils are distinctly different
