Opis:
In this paper a novel definition and understanding of colour correlogram has been proposed. The proposed colour correlogram generalizes the spatial graylevel dependency matrix (SGLDM) to the case of colour textures. This generalization is based on perceptual colour difference measure expressed in the language of the CIELab colour space components. Application of the colour difference instead of arbitrary colour indices or colour components themselves allows to avoid colour-shuffling palletization and introduction of multidimensional objects, respectively; the proposed perceptual colour correlogram is a single 2D matrix. At the same time, a simple relation of the proposed colour correlogram to the spatial graylevel dependency matrix for graylevel textures is retained. Based on this relation it will be shown that there exists a vector of statistical features built from the perceptual colour correlogram which can be used to describe textures in perceptual terms. These statistical features and their abovementioned perceptual interpretation generalize Haralick concepts derived for the SGLDM.

Opis:
The tasks of transport systems include the realization of the assigned transport tasks by the utilization subsystem comprised of elementary subsystems of the man - technological object (driver - vehicle) type. In order to assure the appropriate realization of the transport task it is necessary to maintain the required number of vehicles at the state of task worthiness. It is achieved as a result of the realization of service and repair processes at the logistics subsystem posts. In case of the transport system, the task assigned to the logistics subsystem is determined by the number of technological objects (vehicles) which should be serviced as well as the length of the time interval during which they are to be serviced. The task determined in this way is realized by teams of specialists at each logistics subsystem post, equipped with appropriate devices and tools. One of the methods of the evaluation of the level of the realization of worthiness is defining the efficiency of the logistics subsystem posts. The article presents the model of defining the efficiency of logistics subsystem posts in the transport system. The presented model measures the efficiency of the logistics subsystem through the probability ofservicing of the required number of vehicles over an assigned time interval. The obtained characteristics have been presented in general terms as well as for exponential and Erlang distributions. Then, for the utilization data obtained from the tests conducted in an existing transport system, the values ofanalyzed characteristics were defined. The presented results are the effect of research conducted as part of a larger research project pertaining to the creation of a decision-making model of controlling the availability of a transport system.

Opis:
The article presents a determination method of transport means service ability in a real city transport system. The considerations have been demonstrated on the basis of a real city bus transport system in a chosen agglomeration. The executive subsystem consisting of elementary subsystems of the type human - technical object (operator - transport means) whose service ability and reliability have a direct influence on capability to perform the transport task is directly responsible for accomplishment of the city transport system tasks. In order to develop a model of means of transport serviceability there were determined significant states of the operational use process and there was made a division and reduction of the number of states in terms of the availability criterion. On this basis, an event model of the process of transport means operational use, and then a mathematical model of this process, were built with the assumption that its model is a homogenous Markov 's process X(t). Next, boundary values of availability coefficient for the distinguished availability levels of transport means used in the city transport system were determined for operational data obtained from a real city bus transport system. The discussed model for determination of transport means availability is an initial one, developed on the basis of a nine-state model of operational use. In further part of the paper, there will be developed a resultant model of transport means availability determination (semi-Markov 's sixteen-state model), being a component of a wider, decision model for creation and assessment of transport means availability.

Opis:
An anthropo-technical system is a pair Human -Technical Object performing their tasks in the environment E . In systems of this type threats can be posed by a human H, technical object TO, and the environmental impact on the technical object and people present within the system or its environment. The level of undesirable influence of the human factor on safety of the system operation depends on the human location in the analyzed system. In the work there has been madę an attempt to develop a method for assessment of undesirable errors of people situated in an anthropo-technical system and its environment. Error is an inseparable attribute of human behaviour. Depending on the situation, a human error can lead to deviations from the terms of task accomplishment, it can threaten their safety and be the cause of an undesirable event occurrence. Errors can be divided into the following groups: Training errors these are errors connected with the technique of vehicle driving, decision errors which in situations posing a threat to the system safety largely depend on the situation assessment, making and following a decision of rational control of the vehicle, and Information reception errors resulting from failing to notice signals informing about operation of the vehicle particular subsystems or a change of the road conditions or noticing them too late. For this purpose an algorithm of assessment of people 's undesirable actions has been developed. The proposed method for assessment of the impact of undesirable actions of people involved in an antropo-technical system and its environment is a complex method which accountsfor different human behaviours.

The article presents the method of evaluation of the availability of the utilization subsystem in a transport system. The method includes the defining and comparison of the values of the availability of the utilization subsystem to the value of the required availability. The article also deals with the way of defining the minimum availability of an individual technological object (means of transport) as well as the minimum number of technological objects used in the system, in order for the obtained value of the availability of the utilization subsystem to exceed the value of the required availability determined by the parameters of transport task. The values of the availability of the utilization subsystem are defined according to the availability of an individual technological object, the number of objects used in the system as well as the structure by which the individual technological objects are linked. The availability of the individual technological object was defined on the basis of a constructed mathematical model of the utilization process realized in the tested transport system. Then, for the utilization data obtained during tests conducted in an existing transport system, the values of the analyzed characteristics were defined. The presented results are the effect of research conducted as part o f a larger research project pertaining to the creation o f a decision-making model of controlling the availability of a transport system.

Introduction. A correct diet plays an important role in the prevention of malignant tumours. The risk of the disease may be reduced by introducing a number of changes to the daily diet. The most important changes concern the amount of fat in the diet, dietary fibre, antioxidants in the food and the reduction of substances having a significant impact on the development of malignant tumours. Objective. The aim of the study is to analyse the role of selected modifiable lifestyle factors affecting the development of ovarian cancer. Materials and method. The study covered healthy women and women with diagnosed ovarian cancer. A total of 850 women aged between 21–84 were studied. The study included women visiting the Gynaecology and Obstetrics Hospital of the University of Medical Sciences in Poznan, Poland, between 2011–2013. Patients recognized with malignant ovarian cancer were qualified into the study based on the histopathological examination of the material obtained during surgery. Results. Respondents who consumed fruit and vegetables several times a week have the odds ratio OR = 0.29 level; 95% CI 0.04–2.01 (p =.2085), compared to women not consuming fruit and vegetables at all. Consumption of 100 g of French fries and potato chips several times a week, results in a 2-fold increase in ovarian cancer. The OR for this group of women amounts to 2.06; 95% CI 0.53–7.99 (p=.2966). Conclusions. A diet rich in fruit and vegetables, including bulb vegetables, and grain products containing whole grains, should be introduced. It is recommended that the consumption of popular fast foods be eliminated.

Opis:
In the article, a method for assessment of risks connected with a technical object functioning has been studied, in a selected operating system. An urban system of bus transportation, in a selected urban complex, has been chosen as the research object. Functioning of each technical object operating system, including transportation systems, is dependent on its possibility to perform properly the assigned transport task. One of the methods for assessment of the transportation system ability to accomplish the assigned transport task in a proper way is determination of the transport means operation risk. The presented approach involves determination of indexes defining the risks connected with functioning of one technical object (transport means) in an executive subsystem. Indexes of the risk connected with functioning of a single technical object have been determined on the basis of a mathematical model of the operation process, in the studied transportation system. On the basis of the identification of the authentic transport system and the means of transport operation process carried out in it, crucial operational states were designed as well as the possibilities of transferring between the particular states. Based on that, an event-centered model of the use of the means of transport was built, followed by a mathematical model of that process. A Mathematical model of the operation process has been developed with acceptance of an assumption that the process model is to be represented by a homogeneous Markov model X(t). In this paper, the transport means operation risk is determined as a product of probability (or sum of probabilities) of its being in an undesirable state (states) of the Markov model of transport means operation process and the size of the damage in effect of being in the state (states). The size of the suffered damage is measured by a product of time and unit cost whose quantities are connected with being in the operation process undesirable state or states. Assessment of risk connected with technical objects operation and maintenance can be the point of reference to formulate design requirements concerning durability and reliability of the operated objects (transport means) as well as assumptions concerning design or modernization of the technical means necessary for assurance of the vehicle availability in a given transport system.

Opis:
Systems of public transport carry out their tasks on the territory of a given town and in the suburbs performing the same functions as in towns. A distinctive feature of this type of system is performance of its task for twenty four hours, in different traffic intensity conditions over an assigned administrative area. This type of variables has a large influence on occurrence of undesirable events (failure of vehicles and their devastation, collision and accidents). In the work, an attempt of identification of undesirable events occurring in the analyzed transport system has been made. Moreover, an analysis has been made which covers one day of the week, time of the day and weather conditions in which particular events took place. Another aspect of the work was to make an analysis of the vehicle driver's age, job experience and a given hour of work on the day of the event occurrence. Obtainment of such data allowed demonstrating the structure of events according to the criterion of the event type, and costs connected with bringing the damaged transport means to the state of serviceability. The obtained results of experimental tests provide a basis for taking rational decisions by decision makers employed in a given system. These decisions are supposed to reduce the number of undesirable events occurrence and costs connected with them.

Objectives. The aim of the study is to determine the scale of interregional migrating patients’ hospitalizations in Poland in 2013–2017, as well as their demographic and medical factors, total costs and time changes. Materials and method. Data from the NHF (National Health Fund) regarding hospitalizations in a given province of patients registered in another province in Poland in 2013–2017 were statistically analyzed. Times series analyses as well as coefficients of correlation, determination and variation were used. Results. The number of patients hospitalized outside their regional registration and the cost of their hospitalization increased from year-to-year during 2013–2017. There was a large variation in provinces in terms of inflow of patients and costs of their hospitalization, while there was only a small variation in terms of outflow of patients and costs of their hospitalization in the analyzed years. Among the patients hospitalized outside the province where they were registered, there were more women then men, while the age group was dominated by 60-year-olds and their share in the subsequent years increased, while the share of other age groups remained unchanged or decreased. The most and increasingly more from year-to-year hospitalizations outside the regional registration were due to neoplasms and diseases of the circulatory system. Conclusions. The results of the study may significantly contribute to the proper planning of securing the health needs of the inhabitants of particular regions, and to improving the quality and economic efficiency of health services in individual NHF branches.

Opis:
In the article, a method for determination of the technical object availability, GO (r) in a finite time interval x, defined by the time of the transport task duration, has been discussed. All of the study has been presented on the example of a selected system of technical object operation - a system of transport means operation, in a big urban complex (more than 400 thousand inhabitants). Direct performance of the transport tasks in the analyzed system is the responsibility of an executive system consisting of elementary subsystems of the type operator- transport means. Availability of transport means elementary subsystems is crucial for efficient accomplishment of transport tasks. The presented method involves determination of the technical object availability, on the basis of a mathematical model of the operation process which takes place in the studied system, taking into consideration the technical object reliability characteristics. For this purpose, significant states of the transport means operation have been determined and they have been classified in terms of the availability criterion. Basing on this, an event and mathematical models of transport means operation process have been developed, with the semi Markov homogenous model serving as a mathematical model of the studied operation process. Also, values of the analyzed characteristics have been determined.

Opis:
Every year in Poland, approximately 22 million tons of dangerous materials is transported, which, apart from the German railway, places it on the second position in Europe. The most numerous group of dangerous materials include items of class 3 (liquid, flammable materials), especially liquid fuels. In order to prevent accidents and remove their effects, the European Union countries have developed an international code regulating transport of dangerous materials by railway, RID. Every year 110 billion ton kilometres of dangerous materials are transported on the territory of the EU. Materials carried by road transport account for 58%, by railway 25% and by water 17% of all the transported dangerous products. Transport of dangerous materials accounts for 8% of all freight transports in the European Union. Having in view natural environment protection and safety of people, there are carried out works on one legal act to account for all the three transport branches. Railway transports of dangerous materials are performed in a safe way and rare, in terms of the transports number, accidents and failures do not cause harmful effects, neither on people nor the natural environment. In the paper, there has been made an analysis of transport procedures and threats which occur while carrying dangerous materials. On the basis of carried out investigations an assessment of the risk factor in the studied process has been presented. General rules for transport of dangerous materials by railway and their classification have been presented, markings according to RDI regulations. An attempt of threats identification and analysis of the maim causes of undesirable events occurrence during railway transport of dangerous materials has been made by the authors of this work.

Opis:
Introduction. Cervical cancer is the fourth neoplasm in women with respect to incidence. In Poland, both cervical cancer incidence and corresponding mortality are gradually decreasing. Despite these improvements, the epidemiological situation significantly deviates from European standards. Poland has one of Europe’s lowest five-year survival rates at 54.1% for patients diagnosed in 2000–2002, compared to the European mean value of 62.1%. Objective. The aim of this study is to present health policy programmes related to HPV vaccinations run by local self-government units in 2009–2016. Materials and method. The research is based on analysis of already existing data developed by provincial governors and annual information reviews on health-policy programmes implemented by local self-government units presented to the Ministry of Health. All the programmes that included HPV vaccinations have been subjected to analysis. Results. In 2009–2016, local government units implemented a total of 1,204 health policy programmes that covered HPV vaccinations. Under these programmes, 2.05% of girls aged 10–14 were vaccinated. Percentage-wise, these were communes that contributed the most financially to the HPV vaccination programmes, whereas the counties the least. Conclusions. Local self-government’s programmes covering HPV vaccinations conform with the trends outlined in strategic documents on fighting neoplastic diseases. It is possible that the availability of HPV vaccination was limited for girls living in rural communes. Differences in the number of programmes, number of vaccinated girls and the financial outlays allocated for the implementation of HPV vaccination programmes in particular provinces, may be determined by the epidemiological situation in a given region, measured by the incidence rate of cervical cancer.
