Background: The International Classification of Functioning, Disability and Health for children and adolescents (ICF CY) has been proposed as a possible framework for evaluating assessment and rehabilitation practice in children with Specific Learning Difficulties (SpLDs).Aim: The aim of this case report is to describe an evaluative and diagnostic process based on the ICF CY framework for a SpLD patient to show its applicability to this kind of developmental problem.Method: A 10-year-old boy with difficulties in reading and writing was assessed both traditionally administering a set of cognitive and language test batteries and, innovatively, with the ICF CY checklist aimed to estimate the functioning profile of the child.Results: The reasons for implementing the recent ICF CY as a framework to assess SpLD in children and to set the goals of interventions were supported. Whereas traditional assessment gives a validated parameter to evaluate the cognitive level and specific difficulties in reading and writing, ICF CY enhances the traditional diagnosis embracing both impairment and social factors to consider when selecting appropriate goals to bring about change in the lives and in the school experiences of children with SpLD, and it gives important cues to teachers, rehabilitators and therapists.Conclusion: ICF CY gives caregivers the opportunities to work together not only to provide direct intervention with the child, but also to work in partnership with the child's family, friends, school and society.

Physical fitness and health are two concepts that more and more evidence show their close relationship. The main aim of this paper is to provide an assessment protocol accessible, affordable and easy to apply, to assess fitness and health. To test the protocol, a total amount of 115 participants (59 men and 56 women) aged 25.9 years were assessed. The assessment protocol is designed and tested for application in a population over 18 years of age. It was used to assess the University of Balearic Islands community users. Based on evidence and validated tests (Alpha and Afisal test batteries, Stepping Queen College Test), the following measures for the design of the protocol for assessing the level of fitness and health were recorded: anthropometry (weight, BMI, body fat, waist circumference), fitness (lower extremity strength, upper body endurance, hand grip strength, maximum oxygen intake, flexibility), and blood pressure. The assessment protocol include the previous action of the reception of the participant (explanation and administering of the International Physical Activity Questionnaire and the Physical Activity Readiness Questionnaire) and an ending action where a report of the results obtained and individual recommendations to improve the overall fitness and health level is provided to each participant.

Groundwater resources play a dominant role in water supply in Serbia, and to manage them properly, an assessment of their quantitative and qualitative status must be given. The concept of quality groundwater management is the implementation of EU Water Framework Directive (WFD-2000/6/EC). In this, groundwater monitoring has the highest role, which should provide a comprehensive insight into the quantitative and qualitative characteristics of water in a particular area (Stevanović 2011). The research area in this case is karst landscapes of Serbia. The water bodies of karst groundwater have been identified in the Carpathian-Balkan Mountains of eastern Serbia and in the Dinaric area of western Serbia. Groundwaters of alluvial aquifers along the major rivers are systematically monitored, however, karst and artesian aquifers are not covered by the monitoring network. The current state of monitoring network in the karst of Serbia is, to say the least, unsatisfactory – only the spring of Mlava is observed by the Republic hydrometeorological service of Serbia. EU Water Framework Directive proposes water resource management at the level of river basins, so therefore, prior to network organization, the grouping of existing water bodies of karst groundwater was performed. The basic rule for grouping water bodies is that all bodies must belong to the same river basin and the groups provide reliable data for assessing the status of individual water bodies. Then topographical, geomorphological, hydrographic, geological and hydrogeological characteristics of the terrain were analyzed. According to Poledica (2015) and Stevanović (2015), 25 groups of water bodies in the areas of exploration have been singled out, 13 of them in western and 12 in eastern Serbia. For each group a representative monitoring network has been determined. 104 observation facilities have been selected in the domain of quantity and 53 facilities in the quality domain. This is the total number of observation points that are further sorted by priority. Including the economic factor, it is proposed to gradually develop monitoring networks. Beginning of observation will start in a period of 5 years from now, when observation facilities of first priority (springs of water supply) will be included. The observation facilities of second priority will be included in a period of 10 years from now and those of third priority will be included by 2035. Karst springs and purpose-built piezometers within the source where there are already wells for water supply provide the largest numbers of observation points. Also, hydrological stations are located on watercourses near karst springs where flows during the dry period of the year will be monitored. The final results are presented in the form of hydrogeological maps of Eastern and Western Serbia, which contain water bodies with observation points. These maps were made using the software package ArcGIS. On all facilities, it has been determined which parameters will continuously be monitored (content of observation) and how often (frequency of observation). The level of water will be observed continuously on the places where piezometers will be drilled. Discharge of springs will be observed each other day. Discharge regime of karst springs is studied enough only after many years of research. The reconstruction of monitoring network is suggested after six years. Microbiological and bacterial composition will be observed at least six times a year and other qualitative parameters at least four times a year. Spring discharges and level of groundwater belong to quantitative parameters. Dissolved oxygen, pH value, electrical conductivity, nitrates, turbidity and microbiological composition belong to qualitative parameters. It is very important to include all institutions that are the direct users of these resources, especially water supply system, industry and institutes for public health, and ensure the good cooperation and communication between them. studied enough only after many years of research.

The article introduces the Polish adaptation of the Work Regulatory Focus Scale. The authors tested its validity in three studies. Confi rmatory factor analyses vindicated the two-factor solution with a lowcorrelation between promotion and prevention scales and their relatively high reliability (Study 1). We observed the expected differences between dissimilar professions in the levels of regulatory foci (Study 2). Moreover, the tool allowed us to predict participants’ results in a different criterion – creativity (Study 3), by demonstrating that promotion-oriented participants are more original, fl uent and divergent in producing creative ideas than prevention-oriented participants. Implications for the results and the WRF Scale are discussed.

The article examines issues related to the civil protection of the population of Poland in peacetime after 2007, when a new law on crisis management was adopted. The article starts with an overview of basic requirements set for civil protection in Poland in peacetime. It looks further at the current state of the legal framework, organisation and resources for such civil protection. Finally, the article identifies requirements for improvement of civil protection in peacetime in Poland and assesses the chances for implementing them. The research revealed that the problems related to civil protection were not covered in the existing literature in a coherent manner. The current legal requirements for civil protection in Poland in peacetime can be found in various legal regulations and are not contained in a single framework document. The assessments of the current state of civil protection in Poland in peacetime conducted by the Supreme Audit Office suggest an urgent need for improvement. Improvements are needed in the field of comprehensive legal regulations, appropriate planning and procedures, and more efficient use of financial resources to ensure sufficient resources for civil protection of the population in peacetime.

Local development is a dynamic process which mainly relies on qualitative and quantitative changes, accordingly to the needs of the local communities. One of the decisive circumstances of local development is an efficient road infrastructure. The main problem, in terms of road projects, is their socio-economic evaluation. The article presents a model for assessing S16 national road construction project, on the basis of four groups of indicators. The indicators monitor the changes occurring in the districts, located along the road corridor S16, within the framework of sustainable development. Results of the research give opportunity to a more detailed analysis and evaluation of road projects, furthermore they make a strong foundation for the exploration of cause-and-effect relations between the investments in infrastructure and the quality of life in the region.

The use of ultrasonic energy has created versatile possibilities of their applications in many areas of life, especially in hydro location and underwater telecommunications, industry and medicine. The consequence of a widespread use of high intensity ultrasonics in technology is the increased number of people who are exposed to such ultrasonic noise. Therefore it is important to determine the types of machines and other devices that are responsible for the emission of ultrasonic noise (10-40 kHz of central frequencies of one-third octave bands) as harmful and annoying hazard in the work environment. This paper presents ultrasonic noise sources frequently used in industry and preventive measures reducing the exposure to ultrasonic noise. Two types of ultrasonic noise sources have been distinguished: machines and other devices used to carry out or improve production processes, the so-called technological sources and sources in which ultrasonic noise exists as a non-intentional result of operation of many machines and systems, the so-called non-technological sources of ultrasonic noise. The emission of SPL has been determined for each groups of devices based on own measurement results.

We have investigated the relationship between performance in sports exercises and perceived difficulties in physical ability tasks for boys and girls. In order to assess physical abilities in sport, we conducted experiments concerning methods for self-evaluating the difficulty of physical ability required in sports exercises through implementation of creative vaulting tasks in addition to Eurofit and Evareg tests. Based on a hypothesis that specific physical abilities could predict performance in physical education for boys and girls, we distinguished the relationship between genders concerning perceived difficulty for varied ability tasks. Although sporting exercises performance was high among boys rather than girls, there was no significant difference in perceived difficulties of physical tasks between genders. We highlight how perceived difficulties among students appears to have resulted in higher student motivation levels, and increased desire to improve performance for more effective learning and teaching experience. We recommend that methods of perceiving difficulties in sport exercises need more exploration for better practices.

The chapter has been intended to provide a comprehensive understanding on one class of reliability models used to perform probabilistic risk assessments. This is the class of binary-based conceptual models. This class of models allows assessing events occurrence, system states identification, states transitions and corresponding relevant probabilistic dynamic quantities. Besides, it allows the binarization of multistate systems so that ever bigger systems can be modelled, under conditions. The term “system” is used in its widest sense to include physical engineering systems, processes, and any structured set of actions/events. Consequently, the modelling capabilities cover sequential events and cycling transitions. The move from “risk management decision-making” to “risk-informed decision-making” paradigm has obviously created the right environment to develop and implement risk-based decision-making models in a variety of sectors. A brief and short non-exhaustive survey is presented identifying sectors using these models to assess risks in support to decision-making.

This study aimed to analyse the relationship between the formative assessment (FA) of Physical Education teachers and the level of self-concept of primary school students. In this descriptive cross-sectional study of 122 schoolchildren, self-concept was assessed using the Piers-Harris Self-Concept Scale and the teacher's formative assessment practices through the teacher performance questionnaire associated with formative assessment practices whose scores were validated. The analysis of bivariate correlations showed that higher values in proactive FA correlated with lower values in physical self-concept and higher values in behavioural, intellectual, and social self-concept (p < .05, for all) and interactive FA with higher values in social self-concept (p < .05). The simple analysis of variance detected statistically significant differences in proactive and interactive FA (p < .05, for all) in favour of those who had a higher level of self-concept. In turn, the linear regression test indicated that higher values in retroactive FA are associated with higher values in social self-concept (p < .039) and, that higher values in proactive FA are associated with lower values in physical self-concept (p < .023). It can be concluded that the FA of the Physical Education teacher can be a differentiating element in the development of self-concept.

Background: From the public health perspective, it is particularly important to establish links between a persons' perception of their own health and their predispositions to undertake pro-health behaviours that enable them to maintain proper functioning of their body. In the case of the paediatric population, it is crucial to emphasise that adults are responsible for the adoption and development of appropriate health-enhancing behaviours by children. The aim of this study is to verify parents' perception of the level of children’s physical activity (PA) in comparison with objective measures describing children's physical fitness. Material and methods: Material for analysis consists of the results of anthropometric tests and cardiopulmonary exercise capacity of children as well as questionnaires concerning 28,891 children completed by parents. Results: In more than 40% of the sample, the subjectively assessed level of PA was not consistent with the cardiorespiratory fitness level. It was observed that the correct assessment of the level of PA of children is more common for girls, increases with the age of the child and with the level of parental education.

This paper presents a potential monetary assessment of natural habitats based on a method worked out in 2003 in the Czech Republic. The assessment was prepared for the reclaimed flooded mining pit in Suszec. The analysis was focused on three variants of real and potential habitats from the reclaimed land. Natural values of the flooded mining pit have undergone changes due to afforestation reclamation activities. It has been calculated that the value of natural habitats expressed in numbers will decrease by 70.7% in comparison to the area prior to reclamation, whereas the monetary value of the natural habitats will decrease by 10,319,519.00 PLN. An important element of the assessment includes recognition, diagnosis and evaluation of the actual state of natural habitats by preparing a detailed inventory and determining the most valuable species of plants and animals as well as landscape values. Unfortunately, at present in Poland there is no clear and explicit method of estimating the assessment of lost natural value that would allow approximating the monetary value of a given terrain and determine the most favourable direction of its management. Application of monetary assessment of natural habitats requires its adjustment to Polish conditions. Due to the similarity of climate and geomorphological conditions in Central Europe, it is possible to adopt elements of habitat assessments used in the Czech Republic and in Germany. Natural habitat assessment will provide a solid base for preventing conflicts caused by the needs of economic development at the expense of local protection of the natural environment. As a result, it will be easier to achieve an agreement between different parties in the investment process, and, moreover, the assessment method will prevent additional financial losses, generated during the process of achieving functionality by the habitats. Correct analysis of the values of natural habitats may significantly reduce losses in the natural environment and aid in the selection and choice of the most relevant reclamation method.

The main objective of the research was to determine how temporary employees perceive the process of their onboarding in the context of the efficient performance of their responsibilities. The analysis covered the information obtained by the employee during onboarding, such as the employer’s expectations concerning the position in question, organization of work, procedures and values applied at the company, as well as work evaluation terms. A quantitative research was held based on a questionnaire filled in by 286 respondents. The study revealed that temporary employees had a good opinion of the methods of onboarding. It turned out that the opinion on onboarding, especially with respect to work organization, worsened with age. The study also determined that with increasing level of education, employees’ opinion worsened with regard to the completeness of information provided during onboarding and concerning work evaluation methods and the values applied at the company.

Music performance anxiety (MPA) is a relatively neglected psychological phenomenon that rarely appears in mainstream psychological journals or textbooks. To date, this field of inquiry has focused primarily on professional and amateur adult musicians or college level music students. With the exception of a small number of recent additions to the literature, there have been few studies examining the experience of MPA in younger musicians. In this paper, we review our work on MPA in general, and summarize our recent work with young musicians. We argue that the experience of MPA may begin early in a musical career and that the characteristics of this experience are qualitatively similar to those experienced by adult musicians. There are therefore compelling reasons to address MPA early and to take a strong preventive focus on a condition that to date shows persistence over time and only modest response to available treatments.

Precise measurements of rapid eye movements (saccades) are becoming more widespread. Because is important to answer the question whether how is a measurement error. This paper presents the measurement of about 3000 saccades in one person. It was performed in 14 times the same set of tests. For each of the 14 studies calculated mean and standard deviations of each parameter of the dynamics of eyeball movement, i.e. duration, peak velocity, average velocity, slope, sharpness, Q, and amplitude. These parameters were calculated depending on the amplitude, the type of the task and direction of eyeballs movement (left or right). The results show that the saccadic parameters are a good indicator to assess psychophysical functions.
