Opis:
Ship collision risk index is the basic and important concept in the domain of ship collision avoidance. In this paper, the advantages and deficiencies of the various calculation methods of ship collision risk index are pointed out. Then the ship collision risk model based on complex plane, which can well make up for the deficiencies of the widely-used evaluation model proposed by Kearon.J and Liu ruru is proposed. On this basis, the calculation method of collision risk index under the encountering situation of multi-ships is constructed, then the three-dimensional image and spatial curve of the risk index are figured out. Finally, single chip microcomputer is used to realize the model. And attaching this single chip microcomputer to ARPA is helpful to the decision-making of the marine navigators.

Opis:
Using data on work accidents and annual mining statistics, the paper studies work-related accidents in the Spanish energetic mining sector in 1999–2008. The following 3 parameters are considered: age, experience and size of the mine (in number of workers) where the accident took place. The main objective of this paper is to show the relationship between different accident indicators: risk index (as an expression of the incidence), average duration index for the age and size of the mine variables (as a measure of the seriousness of an accident), and the gravity index for the various sizes of mines (which measures the seriousness of an accident, too). The conclusions of this study could be useful to develop suitable prevention policies that would contribute towards a decrease in work-related accidents in the Spanish energetic mining industry.

Opis:
The aim of the research was the evaluation of the potential contamination with heavy metals in Fluvisols, used as grasslands and arable soils of Vistula River floodplain in the area of the Chełmiński and Nadwiślański Complex of Landscape Parks. The indicators proposed by Håkanson allow to evaluate the potential ecological risk of the contamination with heavy metals associated with the accumulation of one metal or a combination of multiple metals. The mean total content of Cd, Pb, Ni Cu, Zn, Mn, as well as Fe in Fluvisols at the depth of 120–150 cm was assumed as the content of the local geochemical background and it was: 1.0 mg·kg-1, 22.8 mg·kg-1, 26.9 mg·kg-1, 1.4 mg·kg-1, 60.8 mg·kg-1, 591 mg·kg-1, and 17.6 g·kg-1, respectively. The values of the indicators such as contamination factor (CF), enrichment factor (EF) revealed higher levels of the accumulation of heavy metals in the soils of grasslands, which shows that the method of their use has a significant effect on the total metal content. Contamination with heavy metals in the surface layer of the investigated Fluvisols was found, and in terms of the content with cadmium a moderate and considerable potential ecological risk was reported. Due to the fact that no unfavourable effect of trace elements on the riverside environment was proved and that the floodplain areas are under agricultural use, to evaluate the contamination with metals, the limit values for the soils of agricultural land were assumed as stipulated in the Regulation of Minister of the Environment of September 9, 2002. According to that criterion, the soils studied do not qualify as contaminated with metals. Only in one of the soil sampling points the total content of zinc was higher than the one determined as the maximum for agricultural land soils, namely 350 mg·kg-1. A significantly positive correlation was noted between the content of C org and the total content of metals as well as very numerous interactions between metals. The results of cluster analysis confirm that the method of use determines the concentration of metals in the surface layer of the Fluvisols studied.

Opis:
In this paper, two indexes for own ship risk collision assessment in the restricted water are proposed. The first one concerns the collision threats for ships. The second one describes threats that are generated by human error. It is carried out dynamically with accordance to changes in time. To realize the main aim of the paper, the definition of the extended domain of the ship is introduced. Furthermore, the rules to determine the indexes and range of their values are developed. Finally, a comprehensive model and its potential application are presented. There are some important things to take into account during the model development: the interface, the levels and type of the output information, the type and accuracy of the information about the position and movement dynamics of the particular ships. It gives the opportunity to consider the different operation levels. In addition, it also allows us to take into account the different levels of measurement and the collision risk warnings. This approach can be helpful for both the VTS operator and OOW, the ship’s navigator, as the tool to support the safe navigation in restricted water.

Opis:
Risk assessment and management was established as a scientific field some 30–40 years ago. Principles and methods were developed for how to conceptualize, assess, and manage risk. These principles and methods still represent largely the foundation of this field today, but many advances have been made, linked to both the theoretical platform and practical models and procedures. The purpose of the thesis is to perform a review of these advances, with a special focus on the fundamental ideas and thinking on which these are based. We have looked for trends in perspectives and approaches, and we reflect on where further development of the risk field is needed and should be encouraged. The present study is written for readers with different types of background, not only for experts on risk. However, there is a conflict between the cost impact and safety aspect. E&P managers as well as government supervisor authorities are constantly faced with decisions to be made regarding of safety. In order to ensure comparability and to set priorities application of QRA is a useful tool to justify choices made with regard to personnel safety, environmental protection, asset damage and business reputation, it is recommended to apply the systematic cause analysis method and develop the risk management models which contains an integral approach toward the health, safety and environmental aspect.

Opis:
The potential ecological risk index (RI) was employed to evaluate water quality and sediment pollution of heavy metals in the fish Town Rivers, Nigeria. The propensity of the presence of the heavy metals residue in a common brackish water snail (Pachymelania byronensis) that serves as food for human was also examined. Fine-grained surficial sediments from natural depositional zones were collected using Ekman dredge, pooled together and analyzed for the present of heavy metals. The snail samples were randomly hand-picked from the edge of the Rivers or attached to the substrata from August, 2017 to January, 2018 depicting wet season (August - October) and dry season (November - January). A total of 144 P. byronensis (24 per station) were sampled for this investigation. The concentrations of the heavy metals concentration in the sediments and snail tissues were analyzed using graphite furnace absorption spectrometry. The order of occurrence of the metal in the snail is Zn > Cu > Fe > Pb > Cd and their levels remain within their permissible safe levels for human consumption as stipulated by the various regulatory bodies. The risk factor for the metals in the sediments revealed that the Rivers is moderately at risk, which may not pose serious environmental threat and health risks to the resident organisms, but may be magnify along the trophic level. Therefore, sensitization of the inhabitants becomes inevitable, since the level is at threshold, above which may be detrimental.

The paper presents the concept of safety in water distribution systems, which is an important issue connected with its functioning in crisis situations. The research undertaken is directed towards methods of safety assessment relating closely to current world trends, aiming to ensure safety of water supply and use. The paper pays special attention to water consumer safety. Safety levels were assumed on the basis of failure intensity, exposure of water consumers and a number of undesirable event groups. Individual values of the immediate risk index were presented and three categories were distinguished as permissible, tolerable, or unacceptable risk categories, according to presumed action. The risk index can characterize the safety of the functioning of technical systems. The risk index definition is considered as the product of threat ranking. The paper contains the original proposal for a new method of risk analysis and assessment.

Opis:
This article proposes a simple approach to explain credit default swap premia and stock market prices in Poland. Credit Default Swap is an innovative financial instrument designed to transfer risk. Sovereign CDS premia measure investment risk. The aim of the article is to compare the premia of five-year Polish sovereign CDS and the Polish stock market indices – the WIG (Warsaw Stock Exchange Index) and the NCI (NewConnect Index). The key aim of the study is to calculate the Pearson correlation coefficient of premia with indices in the period 2011-2016. According to the theory, the CDS premia were strongly negatively correlated with the main index of the Polish stock market. When the premia increase, the WIG decreases simultaneously, and vice versa. However, in the case of CDS premia and the NCI, a strong positive correlation was documented. When the premia increase, the same is true for the NC index. The relationship can be explained by the presence of low risk-averse investors on the NewConnect market.
Credit Default Swap to innowacyjny instrument finansowy umożliwiający transfer ryzyka. Premia kontraktów CDS typu sovereign jest postrzegana jako miernik ryzyka inwestycyjnego kraju. Celem artykułu jest porównanie premii pięcioletniego kontraktu CDS wystawionego na polskie obligacje z koniunkturą na rynku akcji mierzoną za pomocą indeksu WIG i NCI. Przedmiotem badania jest korelacja premii z indeksami w okresie 2011–2016. Zgodnie z teorią premia CDS była silnie ujemnie skorelowana z głównym indeksem rynku akcji w Polsce WIG. Wzrost premii powodował spadek wartości oraz stopy zwrotu z indeksu WIG i vice versa. Odwrotne wyniki uzyskano w przypadku indeksu NCI, silna korelacja dodatnia. Wzrost premii CDS powoduje wzrost indeksu NCI, a spadek premii CDS spadek indeksu. Nie potwierdza tej relacji porównanie premii CDS i stopy zwrotu z NCI, gdzie wystąpiła niewyraźna korelacja ujemna. Zależność można wytłumaczyć obecnością na rynku alternatywnym inwestorów o niskim poziomie awersji do ryzyka, dla których wzrost ryzyka kraju to okazja do zwiększania zysku i większe zaangażowanie na NewConnect.

Opis:
Analysis of accidents has found driver distraction to be a significant cause of accidents on the highways [1]. Therefore, studying the causes of driver distraction that impact its risk level is needed for a better understanding of accident occurrences. There is general scarcity of research in this field with no established research framework to study driver distractions. This paper proposes a modular research framework for conducting a driver distraction study on Polish city highways. The framework contains guidelines for distraction studies for wide range of cost and time intervals such as a quick, low cost study like analysis of existing accident databases maintained by the cities to relatively higher cost, longer duration study involving field data collection, statistical modeling, and analysis. A city may choose one or more modules to suit their study requirements including statistical and simulation tools to assess and validate the historical or empirical result. The framework is based on the careful modifications and revisions of an earlier transit bus driver study conducted in the Commonwealth of Virginia, U.S.A., and results from this research are presented for purposes of illustration.

Opis:
Metody DSC i DTA pozwalają przy zastosowaniu równań empirycznych wykorzystujących dane kinetyczne na zaklasyfikowanie substancji do potencjalnie niebezpiecznych lub bezpiecznych. Wykorzystanie reguły 100 oraz temperatury ADT24 pozwala określić maksymalną bezpieczną temperaturę prowadzenia procesów technologicznych. Materiały wysokoenergetyczne z punktu widzenia bezpieczeństwa można zaklasyfikować przy użyciu: potencjału Koenena, indeksu termicznego ryzyka, indeksu zagrozenia reakcją, indeksu chwilowej gęstości mocy oraz parametru zagrożenia wybuchem. Wykonano analizy DSC i DTA soli amonowej dinitroaminy (ADN), wyznaczono parametry kinetyczne i na ich podstawie oszacowano bezpieczeństwo użytkowania i warunki bezpieczne prowadzenia procesów technologicznych. Maksymalna, bezpieczna temperatura prowadzenia procesów technologicznych z wykorzystaniem ADN-u jest niższa od 351 K. Sól amonowa dinitroaminy została zaklasyfikowana do grupy związków niestabilnych, potencjalnie niebezpiecznych, zdolnych do wybuchu, do grupy związków wysokiego ryzyka. Uzyskane wysokie parametry indeksów niebezpieczeństwa wskazują na to, że ADN wymaga szczególnej ostrożności w procesach technologicznych oraz przy wykorzystywaniu w formach użytkowych.
DSC and DTA methods, combined with empirical equations based on kinetic data, allow one to classify a substance as potentially harmful or safe. Utilizing the "100 degree rule" and ADT24 temperature enables one to determine the highest safe temperature at which a technological process can be carried out. High energetic materials can be classified from the safety standpoint by using: Koenen potential, Thermal risk index, Reaction hazard index, Instantaneous Power Density and Explosion Potential. DSC and DTA analysis of dinitroamine salt (ADN) were performed. On the basis of the results usage safety and safe conditions of technological process were estimated. The highest safe temperature of the technological process with using ADN is 351 K. ADN was classified to the group of the unstable compounds, potentially dangerous, able to explode and to the group of the high risk substances. The obtained high values of safety parameters indicate that ADN requires great caution when it is used in operational moulds and in technological processes.

Opis:
Sewage sludge from sewage treatment plants has important soil-forming and fertilizing properties. However, they cannot always be used for this purpose. One of the main reasons why sludge cannot be used for natural purposes is its heavy metal content. Sewage sludge from the treatment plant in Starachowice has been subjected to an analysis of the potential risk of heavy metals, especially in terms of their mobility and geoaccumulation. The calculations were made for the concentrations of heavy metals in sewage sludge taken from the treatment plant in Starachowice and in arable soil from the measurement point at the place of its potential use. Geoaccumulation index (Igeo) and potential ecological risk index (PERI) were calculated. The analysis of the results shows that although the geo-accumulation index and the level of potential ecological risk are high and dangerous in terms of agricultural or natural use of sediments, the percentage of metals has been recorded mainly in the immobile fraction from which they will not get into the soil.
Osady ściekowe z oczyszczalni ścieków mają istotne właściwości glebotwórcze i nawozowe. Nie zawsze jednak mogą być one wykorzystywane do tego celu. Jedną z głównych przyczyn, dla których nie można wykorzystać osadów na cele przyrodnicze, jest zawartość w nich metali ciężkich. Osady ściekowe z oczyszczalni w Starachowicach zostały poddane analizie potencjalnego zagrożenia metalami ciężkimi, zwłaszcza pod względem ich mobilności i geoakumulacji. Obliczenia wykonano dla stężeń metali ciężkich w osadach ściekowych pobranych z oczyszczalni w Starachowicach oraz w glebie ornej z punktu pomiarowego w miejscu ich potencjalnego wykorzystania. Obliczono wskaźnik geoakumulacji (Igeo) oraz potencjalny wskaźnik ryzyka ekologicznego (PERI). Na podstawie analizy wyników można stwierdzi, iż pomimo że wskaźnik geokumulacji oraz poziom potencjalnego ryzyka ekologicznego są wysokie i niebezpieczne pod kątem rolniczego bądź przyrodniczego wykorzystania osadów, to udział procentowy metali odnotowano głównie we frakcji niemobilnej, z której nie będą one przedostawać się do gleby.

Introduction and objective. The prevalence of metabolic syndrome and overweight in individuals with normal body weight is connected with higher exposure to type 2 diabetes and cardiovascular diseases. The aim of the study was to evaluate the risk and frequency of occurrence of metabolic syndrome and each of its components among individuals with normal weight. Materials and method. Data were obtained by structured interview, and by measurements of anthropometric factors and blood analyses among 13,172 individuals aged 37–66. The risk of occurrence of metabolic syndrome was analysed in tertiles within the normal range of BMI (18.5–24.9 kg/m2). Results. Metabolic syndrome was diagnosed in 17.27% of individuals with normal weight. A significant increase in the risk of occurrence of metabolic syndrome in females was observed within the second (OR = 2.22; 95% CI: 1.63–3.05) and the third (OR = 3.97; 95% CI: 2.97–5.36) tertiles of normal BMI values. In males, a significantly higher risk of occurrence of metabolic syndrome was noted only in the highest BMI tertile (OR = 2.16; 95% CI: 1.26–3.83), compared to the reference level. Conclusions. A high frequency of occurrence of metabolic syndrome risk factors was observed among individuals with BMI close to the upper cut-off point of the normal range. In order to early diagnose metabolically obese individuals with normal weight it is necessary to check the waist circumference when BMI ≥ 22.5 kg/m2 in females, and BMI ≥ 23.8 kg/m2 in males, where abnormal values should be a signal that further examinations should be performed to determine other risk factors of metabolic syndrome.

Opis:
Zainteresowanie ryzykiem reputacyjnym jest problemem stosunkowo nowym, gdyż ryzyko to nie było początkowo ujęte w regulacjach bankowych. Dopiero okres po kryzysie 2008 r. przyniósł wzrost zainteresowania tym ryzykiem. Celem artykułu jest więc prześledzenie źródeł i konsekwencji problemów związanych z ryzykiem reputacyjnym, szczególnie w kontekście drastycznego spadku zaufania do banków na rynku globalnym w okresie pokryzysowym. Artykuł koncentruje się na analizie różnic w definiowaniu tego pojęcia i problemów metodologicznych z jego pomiarem. W części empirycznej artykuł przedstawia propozycję pomiaru ryzyka reputacyjnego dla banków giełdowych Europy Środkowo-Wschodniej na podstawie samodzielnie skonstruowanego indeksu opartego na perspektywie ważnych interesariuszy. Do badania wykorzystano model panelowy, który analizuje wpływ indeksu na kompleksową ocenę banków giełdowych w krajach Europy Środkowo-Wschodniej.
Reputational risk is a relatively new concept, as it was not initially included in banking regulations. Only the post-crisis period brought about an increased interest in this type of risk. The purpose of this article is therefore to trace the sources and the consequences of reputational risk, in the context of the post-crisis drop in confidence in the banking sector. The paper focuses on the differences in the definition of the term and on methodological problems with its measurement. The empirical part proposes a new approach to measuring the reputational risk, on the basis of the reputational index constructed from the perspective of important stakeholders. The panel models analyze the impact of the index on bank performance in CEE.

Opis:
Interest in reputational risk as a self-standing type of risk is relatively new. The research is driven not so much by regulatory requirements, but by stakeholders’ interest. Therefore, the purpose of this article is to trace the sources of reputational risk and consequences of the problems associated with a bank’s negative reputation. The paper focuses on the differences in the definitions and methodological problems of its measurement. The empirical part proposes a new index measuring reputational risk, based on the perspectives of important stakeholders. The panel models analyse the impact of the index on bank performance in CEE.
