Opis:
Introduction: Preterm birth is the birth of a baby at fewer than 37 weeks' gestational age. Preterm infants are at risk for numerous medical problems including neurological, cardiological, respiratory, and infection. Purpose: To analyse the selected risk factors of preterm births among children under the care of the Department of Pediatric Rehabilitation in Białystok Materials and methods: The retrospective study included 96 preterm children with very low body mass less than 1500 grams. All children lived in the Podlasie region of Poland. We analysed the risk factors for preterm birth based on the medical files. The detailed interview included: the course of pregnancy, diseases before pregnancy, the prevalence of genetic diseases in the nearest family, and the earlier miscarriages. Results: The intrauterine infection (20 cases), fetal distress, (19 cases), uterine bleeding (15 cases), multiple pregnancies (13 cases) were the most often risk factors of preterm births. Only a few cases concerned congenital toxoplasmosis and cytomegaly, malformation of the reproductive system, mother diseases during the pregnancy. The gender of the child did not determine the preterm birth. A significant correlation between preterm birth and the sequence of pregnancy preterm birth was related with first pregnancy in 47% of cases. There was no correlation between i. body mass and sex, ii. earlier miscarriages and preterm births. Conclusions: The risk factors of preterm births are diverse. Most common causes of preterm births were the intrauterine infection, fetal distress, and uterine bleeding.

Opis:
The purpose of this article is to determine the environmental impacts of underground gasification on the population and to analyze the risk of underground coal gasification (UCG) activities using selected risk assessment methods. Coal gas is a regular part of coal deposits and its extraction also allows the use of coal deposits that cannot be extracted by traditional methods. These technologies bring both positive and negative aspects. The paper points out the risk analysis, hazard identification and assessment during the operation of UCG technology using a risk graph and a risk matrix. Identified risks to workers that cannot be reduced should be taken into consideration and appropriate safeguard should be used. For each risk, it is necessary to inform employees about regular education and training. From worldwide experience with this technology, it is possible to analyze risks in Slovakia. Actual gasification produces polluting gases such as carbon dioxide, carbon monoxide, hydrogen sulphide, hydrogen sulphide, nitrogen oxides, tar and ash, and creates a risk that may occur on and under the surface of the site depending on the geological and hydrogeological structure of the deposits. Possible measures to mitigate the adverse effects are proposed for the implementation of this technology. Coal is still one of the main domestic primary energy sources. Currently, only 5 out of 19 deposits in the Slovak Republic are used. Underground gasification could increase the use of Slovak coal and brown coal deposits.

Opis:
The article aims to present practical methods for prioritising the activities of maintenance departments based on the Pareto analysis and the failure risk analysis. Based on the collected data on the number of observed failures and their removal times, commonly known reliability indicators were determined, which were then used to estimate the probabilities and consequences of failures in terms of the risk of loss of production continuity. Based on commonly collected failure data, the developed methods allow proposing to the maintenance departments the sequence of maintenance and repair work to be undertaken in terms of minimising the risk of failure. Risk analysis is somewhat commonly used in the practice of maintenance departments (e.g. RBI, FMEA, ETA, FTE, HIRA). The added value of this work is the use of reliability indicators for estimating the values of risk components, i.e., probability and consequences. The method was developed on the basis of operational data collected in one of the plants of the dairy cooperative and, after assessing the effects of its implementation, it was implemented in other enterprises of the cooperative.

Opis:
In this paper, we propose a new formal model to describe risk analysis and measurement process for IT systems. Our model complies with international standards and recommendations for non-profit organisations. The model accounts for solutions used in widely known and recommended risk analysis methods and provides for evaluation of efficacy of these solutions. A simple example illustrates the application of the proposed model for effective risk analysis of any IT system.

Opis:
It is assumed that the decision analysis is to be used to create rational premises of safe operation of controlled systems under uncertainty conditions. Diagnosis and Decision System is described on the system, which consists of the environment diagnostic facilities human being controlled system. The function of this system is to recognise dangerous operating situations and to generate a warning that some danger might occur as well as to create rational premises for prevention of incorrect decisions that are made during the operation of the controlled system. The processing of messages is carried out in compliance with the conventional Calculus of logic including the double negation law. The Diagnosis and Decision model presented in this paper is universal to a great extent. The block diagram of the diagnosis and decision system, tree of events in a DD system, message creation tables are presented in the paper. The block diagram of the diagnosis and decision system includes Environment, Controlled System, Human Being (Operator, Diagnostician), Diagnostic Facilities, Controlled System or Environment Output State, Hazard Symptom, Warning Signal, Operation Decision. Tree of Events includes occurrence of a controlled system inoperativity or operativity state, presence or absence of: a symptom, a signal; controlled system operation permitting or inhibiting decision, message identity or negation processing law. Message Creation Tables includes presence or absence of: a false symptom, a true symptom, a false alarm, a true ALARM; correct or incorrect: permission, controlled system operation inhibition.

Opis:
The paper deals with the issue of occupational health and safety in a metalworking manufacturing organization. Hazard and threat have been defined when cutting metal materials with a band saw. We assessed the risk by an extended point method, where we determined the risk rate values. In most cases of sawmill work, we found a “moderate” or “negligible” risk. The highest, ‘serious’ risk we found in a possible electric shock. In this case, we have also taken the necessary actions. As a precaution, we have also proposed safety measures for other threats.

Opis:
Regular passenger flows across external borders will also grow significantly in the coming years, in particular at the air border, due to increased global mobility. Visa liberalisation processes and local border traffic agreements also lead to greater responsibility for bordercontrol authorities. Movements across external air borders are managed through a layered approach, where the border is divided into four tiers. In this context, the physical border is gradually becoming a second ary layer for risk assessment, meaning that checking and screening start well before passengers cross bordercontrol posts at airports.

Opis:
The paper is concerned with the developments of risk analysis during the last decade, starting from full range quantitative risk analysis of e.g. a level crossing based on the CENELEC standards EN50126 and EN50129 up to semi-quantitative methods for risk analysis. To expedite this shift from pure quantitative approaches to a more categorized approach were the perennial challenges of insufficient availability of accurate data and the sheer complexity of the reality to be model quantitatively. The article contains both a presentation of a complete quantitative risk analysis for a level crossing as well as a discussion of the crucial points that will need improvement on the basis of a new semi-quantitative standard for risk analysis that has been issued as a national pre-standard in Germany. The relation to the current regulations stipulated by the European Railway Agency and recent publications on this issue are presented as well.

Opis:
The article presents the results of environmental tests performed on scaffolding that were focused mainly on the sound level. The parameters on which we base our analysis are the value of daily noise exposure level and peak sound levels on scaffolding. The noise that affects construction workers on scaffolding, may increase the risk of accidents. We present the results of measurements for twenty two scaffolds in five cities. The analyses carried out confirmed the qualitatively expected dependencies but they allowed us to quantify the impact of the noise on which construction workers on the scaffolding are exposed. The noise occurs continuously throughout the day and can cause faster fatigue, thereby it can increase the risk of accidents in noisy work environment.

This paper discusses the question of classifying the sea areas as sea areas difficult for navigation, unrestricted sea areas and sea areas restricted by land (bottom or shore). Most of all, the article depicts the characteristics of restricted sea areas. It presents the attempt to define in a new way the following notions: "safety of shipping", "safety of navigation", "risk of navigation", "risk of collisions", "navigational obstacle", and "sea area difficult for navigation". In this paper author also presents methods that can be used for estimating safety of navigation (navigational risk) in the restricted sea areas by means of the model of the ship's domain. The essence of the method suggested in the thesis is the systematic approach to sea vessel operation in the aspect of estimating its safety when navigating in restricted sea areas.
