LONG-TERM UNEMPLOYMENT OF THE RISK GROUPS IN THE SLOVAK LABOUR MARKET
No full textLong-term unemployment is a persistent problem for Slovakia. Despite the number of long-term unemployed people in Slovakia has decreased significantly in recent years, it still presents a high proportion of the total unemployment rate. According to the European Commission Report about Slovakia in 2019, while the long-term unemployment rate fell to 4% on a year-on-year basis, it is still well above the EU average of 2.9%. Although growth is expected in the upcoming years, spending on active labour market policies in Slovakia has been one of the lowest in the EU. The study aims at investigating the current situation of long-term unemployment among risk groups in the labour market in Slovakia and labour market measures taken to curb it. It also examines the consequences of unemployment on the family and to seek solutions for the long-term unemployment in Slovakia. The data has been analyzed by a statistical method and proposes solutions to reduce long-term unemployment in the northern part of Slovaki
POOL WATER OVERCHLORINATION IN TIMIS COUNTY, ROMANIA: CASE-STUDY
No full textOBJECTIVE: The aim of the study conducted was to investigate residual chlorine concentrations in pool water from Timis County, Romania over two years (2016-2017).
MATERIAL OF STUDY consisted of a sample of 50 pools from Timis County from which were collected and analyzed 154 water tests.
THE METHOD was an observational inquiry (case-study) of the residual chlorine concentrations considering spatial and temporal distribution and comparing with actual standards (4 groups of residual chlorine concentrations were considered).
RESULTS: Average concentrations of residual chlorine exceeded 0,5mg/l in 30 investigated pools. Monthly mean concentrations of residual chlorine exceeded 0.5mg/l 20 of the 24 months of the investigation period. The maximum value of residual chlorine monthly mean concentration was recorded in July, 2017 and the highest average concentration at the pool I3. An Anova Oneway analysis indicated a statistically significant difference (F=30.312, Sig.0.000) between the 4 groups of residual chlorine concentrations: over 1.5 mg/l / (0-0.5mg/l, Sig.000; 0.5-1mg/l, Sig.0.001, 1-1.5mg/l, Sig.0.009).
CONCLUSION: There is an over-chlorination of pool water of Timis County, Romania, with spatial and temporal variation and statistically significant differences between groups of residual chlorine concentrations
ACNE PREVALENCE, AWARENESS AND PERCEPTION AMONG YOUNG POPULATION
No full textBackground. Acne is a very common dermatological condition, very few studies have been done regarding the knowledge, beliefs, and perceptions about the various treatment modalities and causative factors (nutrition, medication, cosmetics, pollutants, psychological and lifestyle factors and etc.) of acne.
Methods. A quantitative written survey was performed. Survey sample – 451 young people 18-34 years old. Data analysis was performed using SPSS 26.0, calculated percentage frequencies, mean and standard deviation (SD), Pearson’s Chi Square test was used to detect statistically significant differences and correlation analysis was performed using the Spearman correlation.
Results. The study shows that acne affects 49.9% of the surveyed young people. The prevalence of acne depends on the type of skin, tendency to have skin imperfections and genetic factors. Awareness and perception of skin care, factors affecting the occurrence of acne, and treatments used do not depend on the age of respondents.
Conclusions. Young people lack professional knowledge of acne, skin care, and acne-provoking factors. They should take care of themselves, choose the right information from reliable sources and seek the help of specialists. Identifying the negative exogenous and endogenous factors and thus reducing their impact are mandatory for an adequate acne management
FRESHWATER SAPROPEL: BIOLOGICALLY ACTIVE COMPONENTS AND METHODS OF EXTRACTION
No full textPreviously, sapropel has been commonly used in agriculture, cosmetology and medicine in its raw form and there has been no generally accepted method or standard for realizing sapropel extract. However, for sapropel usage in medicine, balneology and pharmacy, it is essential to develop quality criteria for raw sapropel and its extracts.
This review aims at discussing and summing up different techniques for extracting bioactive compounds from sapropel as well as the possibilities of creating quality criteria. This paper covers existing analytical techniques and methodologies; currently, there are few extraction methods using several extractants for obtaining bioactive components from raw sapropel. Different freshwater sapropel types have been described and characterized. Bioactive components in sapropel have been identified and explained. Humic acids and fulvic acids have been identified as the main substances and their extraction methods have been listed. Solid-liquid, ultrasound assisted and supercritical fluid extraction methods have been pointed out as the most suitable. Additionally, analysis and storage conditions of the extracts have been discussed.
There have been found to be no commonly accepted standard methods for sapropel extraction, or for the analysis and characterization of the sapropel extracts. For pharmacological applications, a common approach for the extraction process of active substances from sapropel and the analysis procedures of the extracts need to be established. This review will help equip other researchers with the latest information on this topic

No full textA vegetation experiment was carried out with different amounts of vermiculite mixed with humus depot substrates, tailings pond and mine, in different proportions, and with an application of mineral fertilization and liming. Biomass carbon of microbial origin has the highest values after the addition of 10% vermiculite, simultaneous application of fertilization and liming, and alone fertilization, compared to controls, without ameliorants. The activity of the studied enzymes - cellulase, amylase, invertase and catalase increased with increasing concentration of vermiculite, as well as in the combined application of fertilization and liming. The values of microbial biomass carbon and enzymes are highest in the variants with substrates from the mine
ENGINEERING AND CONSTRUCTION PROJECT MANAGEMENT IN THE DIGITAL TWIN ERA
No full textThe aim of this paper is first to describe the current achievements regarding digitalization technologies in the engineering and construction sector. The concrete technologies presented are the GIS standards as CityGLM and BIM technologies, and as the EUBIMTG initiative. These two technologies can be applied in a common framework building digital twin environments and platforms. These platforms create a huge capacity of gains for the constructions sector in all phases, and for all the actors, as constructions digitalization has a huge unexplored potential. Most of the participants in the value chain will gain from interventions in the engineering and construction (E&C) phases of design, and engineering, construction and operations. Project management (PM) was described as intervention, which creates potential for new business models to be implemented. Virtual modelling can further develop in the direction of virtualization and construction simulation, and contribute towards the successful digitalization of the E&C sector
TESTING OF NATURAL INSULATION MATERIALS USING A CONICAL CALORIMETER
No full textThis paper examines three types of natural insulation materials, such as fiberboard, hemp and straw, from the point of view of fire safety. Cellulose-based materials allow a wide range of applications when used for insulation and weatherproofing of buildings, in particular floors, roofs, ceilings, attics, sound barriers, etc. The use of these materials is increasing in ecological constructions as well as for weatherproofing wood-based structures. In terms of fire safety requirements, the question is: Which insulating material is the safest in terms of fire propagation? The article focuses on natural products used as external insulation systems which are covered by a facade plaster. Each type of insulation is briefly described in terms of its composition, use, and production process. We describe the process of preparation of samples as well as the testing and measurement procedures. Three tests were carried out for each type of material. For a more objective evaluation, results were averaged. The results of the cone calorimeter were used to obtain data for comparison. The aim is to clarify the behavior of the natural insulating material with regard to the heat release rate, ignition time, burning duration, and maximum heat release rate. These are the essential parameters for comparison. The values were compared to determine the safest material from the point of view of fire safety
FLEXIBLE FORM OF EMPLOYMENT: PROSPECTS OF DEVELOPMENT
No full textThe need for the study is justified by the development of flexible forms of employment in the economy with new job opportunities for the international division of labor. The paper analyzed new job opportunities and risks associated with flexible form of employment for the workers, employers and the state individually as well as in relation to each other. The study investigated the future prospects of flexible forms of employment along with its impact on the economic opportunities for the enterprises and workers and conclusion has been drawn. The impact of flexible employment was also investigated on the welfare of the population and the development of national economies in the context of globalization. Three forms of flexible employment: temporal flexibility, spatial flexibility and functional flexibility have been identified to achieve the research goal.
The prospects of flexible form of employment for the enterprise and employee were assessed based on the subjective approach. The rapid assessment and empirical analysis method were used to track the population dynamics and their interest in flexible forms of employment. The results show that the increase in the share of flexible employment in the economy is justified by the increased importance of creative labor in the labor market. Flexible workers represent a diverse population group in terms of the socio-economic structure. The active development of flexible forms of employment has been considered as a manifestation of the self-regulating economy and as a form of adaptation of the population to the changing socio-economic situation. The new agile business integration can reduce the costs of hiring a full-time employee and increases employees’ motivation level. The state needs to institutionalize new forms of employment in order to ensure the competitiveness of the national economy and to ensure budget revenues
APPROACHES TO THE FORMATION OF SUSTAINABLE ECONOMIC DEVELOPMENT OF TRANSPORT SYSTEM
No full textThe world economy as an integrated system has limited growth limits, natural resources are limited, so a new concept of sustainable economic development has emerged, based on a balance of the economy, social goals and ecology. Sustainable development is the development of the country's economy and the global system in which current needs are met without compromising future opportunities. The rapid development of transport infrastructure creates the prerequisites for the sustainable development of centers of macro and microeconomic growth and helps to reveal their potential in the future.
The article considers the role of transport as an additional priority for sustainable development at the macro level and the types / functions of connectivity of economic growth centers in the sectoral and regional aspects.
In turn, the concept of sustainable development of the transport system involves taking into account the features of the transport system as an object of increased danger and a high degree of influence on the main priorities of sustainable development (economic growth, social system and ecology) of the macroeconomics. It was noted that, on the one hand, the transport system, being part of the country's macroeconomic system, affects the priorities of its sustainable development, and on the other hand, has independent priorities for sustainable development in the field of economic growth and efficiency, social potential and environmental aspects, including issues of ensuring security
OPTIMIZATION OF LOGISTICS PROCESS IN CONTEXT OF SMART LOGISTICS BY USING COMPUTER SIMULATION – CASE STUDY
No full textIn the conditions of shipment processing it is important to observe the timetable of dispatch in which the entire processing process is going on. Each element of the processing system is important and it is linked with others by time. This means that the delay of one element causes an avalanche effect. The use of computer simulation helps in optimizing processing processes as a whole. This helps to detect regularities and bottlenecks that have been previously overlooked. The concept of Smart Logistics as part of the Smart Factory using simulation as a tool to estimate the future behaviour of the system. The article describes its own system for determining the number of staff to perform the required activities within the processing process. On the basis of the actual number of shipments, the arrival times and the processing system data, a solution can be described using a simulation tool to determine the number of workers. The simulation helps us to design the number of workers so that they observe the times of truck departures from the processing depot. This guarantees compliance with the timetable at minimum labour costs
