Opis:
Objectives Assessment factors (AFs) are commonly used for deriving reference concentrations for chemicals. These factors take into account variabilities as well as uncertainties in the dataset, such as inter-species and intra-species variabilities or exposure duration extrapolation or extrapolation from the lowest-observed-adverse-effect level (LOAEL) to the noobserved- adverse-effect level (NOAEL). In a deterministic approach, the value of an AF is the result of a debate among experts and, often a conservative value is used as a default choice. A probabilistic framework to better take into account uncertainties and/or variability when setting occupational exposure limits (OELs) is presented and discussed in this paper. Material and methods Each AF is considered as a random variable with a probabilistic distribution. A short literature was conducted before setting default distributions ranges and shapes for each AF commonly used. A random sampling, using Monte Carlo techniques, is then used for propagating the identified uncertainties and computing the final OEL distribution. Results Starting from the broad default distributions obtained, experts narrow it to its most likely range, according to the scientific knowledge available for a specific chemical. Introducing distribution rather than single deterministic values allows disclosing and clarifying variability and/or uncertainties inherent to the OEL construction process. Conclusions This probabilistic approach yields quantitative insight into both the possible range and the relative likelihood of values for model outputs. It thereby provides a better support in decision-making and improves transparency. Int J Occup Med Environ Health 2018;31(4):475–489

Opis:
This article reviews the current research of literature on aggression in childhood and adolescence. The research suggests that a common characteristic of all seriously aggressive children is that they have intense negative effects on the people who interact with them. The longitudinal research has indicated that aggressive behavior is quite stable during childhood and adolescence, and aggression is more consistent over time than most of the other behavioral patterns. Furthermore, aggressive children are referred to school interventions and mental health services at higher rates than children with other forms of psychopathology. The analysis of aggressive behavior of children and adolescents from clinical and developmental points of view is important for assessment of the factors related to a child’s aggressive tendencies and a comprehensive treatment plan design.

Opis:
In this paper, we present the findings of a qualitative analysis of 15,750 comments left by 2,041 participants in a Reconcile web credibility evaluation study. While assessing the credibility of the presented pages, respondents of the Reconcile studies were also asked to justify their ratings in writing. This work attempts to give an insight into the factors that affected the credibility assessment. To the best of our knowledge, the presented study is the most-recent large-scale study of its kind carried out since 2003, when the Fogg et al. śHow do users evaluate the credibility of Web sites? A study with over 2,500 participants’ paper was published. The performed analysis shows that the findings made a decade ago are still mostly valid today despite the passage of time and the advancement of Internet technologies. However we report a weaker impact of webpage appearance. A much bigger dataset (as compared to Fogg’s studies) allowed respondents to reveal additional features, which influenced the credibility evaluations.

Opis:
This paper presents the process of quantitative assessment of selected factors influencing the probability of grounding. All grounding accidents that occurred during one year (2013) in the Baltic Sea area were analysed. The research area was chosen because of very high traffic intensity and a large number of narrow passages that make it difficult for navigation. The research period was limited by the latest data reported by HELCOM up to the year 2013. The Method of Grounding Probability Coefficient (GPC) calculation is proposed to reach the assumed goal. Either internal factors such as the ships size and ship type or external factors such as time of day, wind force and season were taken into account. As a result the values of coefficients describing the impact of various factors on the probability are evaluated. This coefficients, taking into consideration coupling effect, can be used in future in the navigational safety simulation models based on the assumed value of accident probability.

Opis:
This paper presents human and operational factors related to risk assessment during the operations of crude oil, petroleum products, and liquefied gas transfer between ships, called Ship to Ship (STS) operations. The lessons learned from accidents during STS when both ships are underway show that the most frequent accidents occur due to ship handling errors. Several influencing factors have already been identified, however there is still a need to investigate the human factor. Both human and operational factors are interrelated as the operational factors influence the human stress level. This paper identifies the stressors related to the external pressures imposed on the ship’s staff, which can be limited to improve safety. The preliminary study of the influence of particular elements of human factors, e.g., personality traits and stress levels, on the probability of ship handling error is presented.

Opis:
On the basis of systematization and development of scientific ideas, it is suggested to understand the competitiveness of human capital as such a demanded quality, developed and accumulated by education, upbringing, improvement, educational and professional development, the advantages of which provide for the owners of human capital to expand opportunities for labor selection in the labor market, getting more income and other social and economic benefits. Based on the analysis of the existing methodology, an author's approach to assessing the competitiveness of human capital at various economic levels is developed, which is based on a comparative evaluation of the multitude of characteristics of such capital, the construction of matrices with a gradation of such an estimate. Its use makes it possible to determine to what extent, in what directions of development of human capital there is a lag from other competing entities, which leads to the loss of possible benefits from its use in the economy. The main results of approbation of such an assessment in Ukraine are revealed, which show negative trends, a crisis of social responsibility, the need for innovative changes in the development of human capital in order to increase its competitiveness.

Opis:
The impact of wind power plants on the environmental components is assessed taking into account a number of their parameters, in particular the technical characteristics of wind turbines, the characteristics of networks, engineering and other structures. To do this the life cycle of the wind power plants is described taking into account (by way of inventory) all the necessary materials and resources. Waste management scenarios have been developed, the use of which will make it possible to reduce the harmful impact on the environment. Based on the inventory and input data on the wind farm under study, a diagram is generated - a tree of life cycle processes of the wind power plant - to determine the potential environmental impacts. A list of impact categories that represent the load on the environment caused by the wind power plant is defined; also, the relative contribution of harmful factors is determined for each category, taking into account possible scenarios of waste management. Ecological profiles have been built for all potential impacts on the environment. After normalisation and determination of significance, individual estimates of all indicators and their distribution in three categories of lesions were obtained: human health, ecosystem quality and resources, as well as four stages of the wind farm life cycle: production, dismantling and disposal, operation, transportation and installation. The obtained profiles made it possible to determine individual indicators and eco-indicators, expressed in eco-points that characterise the wind farm under study.

Maritime casualty is an event of considerable economic and social impact. For this reason, implemented the reporting systems of accidents at sea, and the Administration was obligated to establish a Commission of Maritime Accidents. On the basis of casualty analysis and reports are developed proposals preventing similar casualties in the future. However, there is no uniform evaluation system which check references of existing regulations and recommendations to the occurred casualties. This paper presents a method to evaluate the used methods of casualty prediction with respect to the real incident and catastrophe.
