The goal of this study was to establish technical and tactical performance goals for elite male volleyball players (Spanish first division). This paper is the result of scientific collaboration between volleyball coaches and researchers. The process of establishing the goals and the reference values of the performance goals was: 1) conceptual analysis, establishing the criteria for the analysis of players’ and teams’ performance (researchers and coaches); 2) mathematical analysis, data collection and data analysis of the possible performance goals; and 3) practical analysis, establishing the performance goals according to their usefulness and applicability following the SMART principle. Seven performance goals were established to evaluate the technical-tactical actions of the players in training and in competition. Protocols utilized can be used as references of how to calculate the technical and tactical performance goals in sport.

The results of investigations on the microstructure of T23 and T24 low-alloy steels as well as P91 and P92 high-chromium steels in the as-received condition and after 70.000 h annealing at 550-650°C are presented. The quantitative analysis of the existing precipitates was performed for representative images of microstructure. The statistical analysis of collected data allowed the parameters of a selected theoretical statistical distribution to be estimated. A forecast of average precipitate diameter and standard deviation of such a distribution for the time of 100,000 hours at 550 and 600°C for T23 and T24 steels and at 600 and 650°C for P91 and P92 steels was calculated. The obtained results of investigations have made it possible to compare changes in the microstructure of various steel grades due to long-term impact of elevated temperature. They have also confirmed the possibility of using, in evaluating the degradation degree of materials in use, the forecasting methods that derive from mathematical statistics, in particular the theory of stochastic processes and forecast by analogy methods. The presented approach allows the development of a forecast of precipitate diameter probability density under the microstructure instability conditions for selected steel grades. The assessment of material condition that takes into consideration, but is not limited to, the precipitate diameter measurement is useful as an assessment component in estimating the time of safe service of power unit elements working under creep conditions.

Objectives: The epidemiology of acute poisonings, observed in Toxicology Unit in Łódź, is the main objective of the study. The authors present frequency of respective kinds of poisoning cases and associated mortality. They discuss also the structure of poisonings with regard to type and causative agents over a period between 2003 and 2007. Materials and methods: The data used for the analysis were obtained from National Poison Information Center in Łódź. They were divided into two groups. The first one comprised information about patients treated at the Toxicology Unit (TU), whereas the other one included cases treated in other hospitals and only consulted by TU staff. Results: Analysis of the data shows that overdosage of medications was the most frequent cause of hospitalization during 2006-2007. It constituted also the leading cause of deaths due to poisoning during 2003-2005. However, it was superseded during the subsequent period of 2006-2007 by intoxication with alcohols which was associated with the highest number of deaths in the latter period. Situation changed dynamically also with regard to the intention of poisoning. Suicidal poisonings constituted the largest group in 2003, whereas poisonings caused by abuse, including dependence-related abuse, were the most frequent in subsequent years. Patients between 15 and 30 years old formed the largest group among the total number of poisonings. Conclusions: The results of our study on epidemiology of acute poisoning in Łódź between 2003-2007 show that poisoning is a frequent cause of admission to hospital and constitutes a major health problem in Łódź district because of large number of hospital admissions, associated mortality and the high proportion of patients at young age.

In the paper, the author outlines the subject of crime among foreigners of Vietnamese origin in Poland. The Vietnamese residing in Poland were characterised as an introduction. Subsequent waves of immigration, their causes, problems of integration with the society, feeling of dissimilarity, and general features of this minority were analysed. Basic statistical data regarding the size of this group, regulations regarding the legality of their stay, and other important information were presented. Work performed in Poland, carrying out business activities, and everyday life were taken into account. In the second part of the paper, crime among the citizens of Vietnamese origin was analysed. The analysis was based mostly on figures extracted from police, penitentiary, and judicial statistics. Data on the number of persons of Vietnamese nationality in prisons and detention centres, the amount of crime related to irregular crossing of an external border, and other data characterising criminal behaviours of this group were presented. Moreover, examples of illegal activities including areas particularly at risk were given. The author emphasised that the Vietnamese are suspected of illegal crossing of external borders, smuggling, drug offences, and unlawful acts related to the widely understood commerce. A statistic regarding the Vietnamese convicted by a final court judgement in 2014 in view of the full extent of crime was demonstrated. In this case, penalties and penal measures ordered by the Polish judicial system and the categorisation of offences compliant with the legislation in effect. To conclude, the crime dynamics in Poland in 2003–2005 was presented.

Opis:
In recent years Poland has been undergoing rapid socio-cultural changes. Along with these changes one can observe a systematic decline in the importance of religious life. This leads to reflection on the direction and depth of transformations, and consequently on the place of religion in the life of future generations. The study attempts to statistically present the religious situation of the inhabitants of Cieszyn Silesia. This is a very specific region mainly due to the diversity of confessions. Historical conditions, as well as the current religious structure make this subject difficult to study, but at the same time very interesting. For a more complete picture, the data from the beginning of the 20th century, as well as from the present day, were used.

Opis:
The aquifer system of the Remila plain (Khenchela, Algeria), covering 250 km2, is one of the semiarid regions where groundwater is heavily exploited for urban supply and irrigation. An integrated hydrochemical and statistical analysis was performed on 70 water samples to identify the main processes and the origin of salinisation of our waters. Chemical analyses indicate salinity values (TDS) ranging from 568 to 1586 mg·dm-3 with an average of 869 mg·dm-3, with sulphate being the dominant ions, especially in the north and northeastern parts of the region. The identified chemical facies are SO4-Cl-Ca in the northeastern part, SO4-Cl-Ca-Mg present in most waters, and HCO3-Ca-Mg in the southeastern part. We applied the statistical approach to group the waters into three categories using Principal Component Analysis (PCA) and Hierarchical Clustering Analysis (HCA); 1) saline waters (23%) (TDS > 1000 mg·dm-3 and SO42-dominance), 2) moderately saline waters (51%) with HCO3- dominance, 3) moderately saline waters (26%) with a mixed facies. The binary ion diagrams used suggest that the main hydrochemical processes are: evaporites dissolution and/or precipitation, accompanied by an exchange and/or reverse exchange of ions. Additionally, another process was detected in the northeastern part of the area; the saline intrusion of Sabkha waters, favoured by intensive aquifer exploitation.

Safe traffic is a key factor for both social players and the sustainable development of the economy. The various interest groups involved in traffic each have their own role in making our roads safe. The large number of traffic accidents and their grave consequences represent a real problem all over the world (see, for instance, the incredibly crowded metropolises of Southeast Asia or the megacities of Latin-American). A successful innovative activity in this field performed on a worldwide scale contributes to solving a critical social and economic issue. Due to the more easily available European statistical data, the paper is going to present the causes of accidents and examine possible solutions. A 2001 objective of the European Union requires a 50 per cent reduction in the number of fatal road accidents by 2010. Although a number of effective measures have been implemented in the field of traffic safety, the number ofroad accidents is still unacceptably high in the EU: a total of 1.3 million accidents per year result in close to 40,000 deaths and 1.7 million injuries. There is a large body of statistical data available (bothfrom Hungary andfrom Europe) and several comprehensive researches discuss the types of accidents. Available analyses are going to made on what kind of active or passive vehicle safety systems could have helped avoid the accidents. These analyses have and still define the main directions for legislation and technical developments.

Opis:
The phenomenon of business failure in Poland came into being anew with the fall of the communist rule – it was the beginning of the 1990s, and the transition period from a centrally controlled market to a market economy was triggered. At that moment the market was a place where verification was being made regarding whether or not companies would be able to function, and consequently should they file for bankruptcy? Bankruptcy can be called a controlling device designed to eliminate the weakest links from the market, leaving the strongest players. This led to the creation of new statistical data, access to which has become easier over the years. This paper presents selected statistical data on bankruptcies of enterprises in Poland in the period 1990-2017. These data are presented by various credit information agencies by sector and region. However, these figures involve no relationship between the number of bankrupt enterprises and the number of operating ones. For this reason, the author calculated the statistical data, taking into account the relevant facts. The paper also introduces the business insolvency index and the newly established business index. The author suggested analyzing both of them in the analysis of bankruptcy data.

The study analyses the number of midwives in the counties of Eastern and Western Galicia in census years 1869, 1880, 1890, 1900 and 1910, and the ratios per cadastral commune, 10,000 square kilometers, 10,000 civilians and 10,000 women in a county. The analysis was based on Austrian and Galician statistical reports. The results of the study confirmed that Eastern Galicia outnumbered Western Galicia in terms of midwives. However, it was in Western Galicia where the rate of growth was higher, and the effects of the 1910 collapse more moderate. This could have been due to an amendment to the 1897 midwifery regulations. The position of individual counties changed, depending on the year and the specific measure. In Eastern Galicia, Lisko county ranked the worst and Horodenka, Śniatyń, Tarnopol, Trembowla, and Brzozów counties ranked the best. In Western Galicia, Limanowa county ranked the worst, while Brzesko, Kraków, Łańcut, Wadowice, Przeworsk, and Podgórze counties ranked the best. There is a strong positive correlation between the rank and natural conditions (water, soil, climate), type of crops, agricultural development and processing, transport system (road and rail), population, and stimulating function of large urban centers. Favorable conditions were correlated with higher values in measures of the number of midwives.

Introduction. Breast cancer is the second most prevalent reason for cancer deaths after lung cancer. Incidence rates have increased worldwide. Aim. To present epidemiology of breast cancer in Podkapackie voivodship. Material and methods. This analysis was performed using a systematic literature search. Results. In the Podkarpackie voivodship up until 2014, the incidence rate of female breast cancer was rising and in 2015 it dropped by 68 cases. Even though the survival rate is increasing, it is still one of the leading causes of cancer deaths placing second after lung cancer. Conclusion. Mortality rate, unfortunately, rose gradually. This shows that even though there is a National Health Program aiming at breast cancer awareness and prevention, it is still not enough to reduce the number of breast cancer deaths.

Opis:
A general dependence of the enzyme catalytic rate on its mass was revealed when a statistical analysis of 17065 records from the EMP database was performed. The estimated activation energy of the catalytic process decreases asymptotically with the enzyme molecular mass increase. The proposed theoretical model postulates the existence of an intermediate complex of the enzyme and the departing product. It allows for the explanation of the discovered mass-energy relationship, as an effect of the global enzyme-product interactions during complex dissociation. Fitted parameters of the model seem to be in agreement with those widely accepted for the van der Waals energy of molecular interactions. Their values also agree with the picture of the hydrogen bonding in the catalytic process and suggest that surface walk can be the favorable way of the product departure.
