    Di\v{s}imo: Anchoring Our Breath

    Get PDF
    We present a system that raises awareness about users' inner state. Di\v{s}imo is a multimodal ambient display that provides feedback about one's stress level, which is assessed through heart rate monitoring. Upon detecting a low heart rate variability for a prolonged period of time, Di\v{s}imo plays an audio track, setting the pace of a regular and deep breathing. Users can then choose to take a moment to focus on their breath. By doing so, they will activate the Di\v{s}imo devices belonging to their close ones, who can then join for a shared relaxation session

    Modeling The Unemployment Rate At The Eu Level By Using Box-Jenkins Methodology

    Unemployment, as a measure of market conditions, appears as a crucial economic problem and a phenomenon with considerable negative social consequences, and, as such, requires attention and adequate approach to finding solutions. Enormous unemployment rates are a reality not only in developing and transition countries, but also in some developed countries. Inadequately conducted privatization, unsuccessful transfer of workers from the public to the private sector, inefficiency in attracting foreign direct investment, and the world economic crisis of 2008 have made unemployment a universal disease of modern society. The paper presents economic models in which the unemployment rate is the central analyzed phenomenon. In this context, an important task of European economic policy-makers is to project future unemployment rates. Box-Jenkins methodology, i.e. the seasonal ARIMA model, is one approach to the modeling of time series, or, more specifically, for forecasting future values. The subject of this paper is the analysis of the evolution of the unemployment problem on the basis of the values in the period from 2000 to 2015, based on the case of 28 countries of the European Union. Building on the research subject, the purpose of the paper is to create the statistical model for forecasting the values of the monthly unemployment rates in the European Union for the future and establishing its trend. Keywords: Unemployment, labor market, Box-Jenkins methodology, the European Unio

    These articles are a result of the bilateral cooperation project ”Assumptions and possibilities of developing innovative models of teaching for accomplishing transparency of university education and for raising competitiveness in national and international knowledge markets”, carried out and financied by the University of Kragujevac, Faculty of Education, Jagodina (Republic of Serbia) and the University of Primorska, Faculty of Education, Koper (Republic of Slovenia), in the period 2017–2019.Modernization of education after 2000 is mainly aimed at standardization in the so-called European cultural space and takes place, in parallel, in different dimensions concerning the organization of education at different levels, financing education and redesigning of immanent internal processes of education by establishing a new curriculum, whose ultimate intent is to provide knowledge to the ”beneficiaries” that will enable them better preparation for performing numerous social roles. An innovative approach to teaching, from basic to higher education, is one of the ways to bring educational practice closer to the demands of a “society of knowledge” – the requirement for an individual to possess specific knowledge, skills and abilities that are in the function of personal and social development. In that sense, it is necessary to realize a kind of symbiosis between institutionalized education and other institutions with educational capacities, such as museums, to achieve better results in the presentation of certain educational contents to different participants’ categories in the educational process in their synergy. This would enable, in addition to the primary effect, a comprehensive and high-quality presentation of educational content, and other effects such as efficiency and equity in education. The subject of this study is a connection between the teaching contents of the course Sustainable Development of the Environment in the study program Teacher at the Faculty of Education in Jagodina with permanent exhibitions of similar contents in museums in Serbia in order to determine the possibility of their connection and joint engagement in presentation and processing of the course curriculum contents. Descriptive-analytical methods were used in this study.Publishe

    Otpadne vode Topole

    In this paper we can see the basic characteristics and the quality of wastewater of Topola before and after the process of purification. Only households and catering Facilities are connected to the town's sewage network, so that at treatment of wastewater, only mechanical and biological procedures of purification are applied. The central place at the Plant for waste water purification is bioaeration pool, where microbiological degradation reduces the presence of organic pollution.The significant reduction of values of basic organic pollution indicators BOD5 (81,84%) and COD (82,27%) in wastewater after the purification process confirm the efficiency and justification of the applied technological process.U radu su prikazane osnovne karakteristike i kvalitet otpadnih (kanalizacionih) voda Topole pre i posle procesa prešićavanja. Na gradsku kanalizacionu mrežu Topole su priključena isključivo domaćinstva i ugostiteljski objekti, tako da su u tretmanu otpadnih voda primenjeni postupci mehaničkog i biološkog prečišćavanja. Centralno mesto u Postrojenju za prečišćavanje otpadnih voda zauzima bioaeracioni bazen u kome se mikrobiološkom razgradnjom smanjuje prisutno organsko zagađenje. Značajno sniženje vrednosti osnovnih pokazatelja organskog zagađenja BPK5 (81,84%) i HPK (82,27%) u otpadnoj vodi nakon procesa prečišćavanja potvrđuju efikasnost i opravdanost primenjenog tehnološkog postupka

    Kinetic Study of Oxidation Degradation of Polyphenols in Sour Cherry and Blackberry Extracts During Storage

    In this study was to investigate the influence of storage time, light and temperature on stability of polyphenols in sour cherry (Prunus cerasus) and blackberry (Rubus fruticosus), were harvested in western Serbia (Rasinski region). Total phenol content was monitored in the fruit extracts during 23 days stored at 7°C under darkness and 90 days storage at 23°C in oxygen. For analyzed extracts, first-order reaction kinetics was established for the degradation process of polyphenols. The temperature dependence of the polyphenols degradation rate constants was expressed by the temperature coefficients Q10 of the process. It is found that the Q10 values of polyphenols degradation in sour cherry and blackberry extracts were 1.247 and 3.239, respectively

    Quality Red Wines: Changing the Content of Anthocyanins in the Process of Ripening Grapes

    Get PDF
    The content of anthocyanins in grape affects the color and sensory properties of red wine. This paper deals with the quality of Cabernet Sauvignon wines examining changes in the content of anthocyanins in the process of ripening grapes. The HPLC results show that the skin extracts obtained from the early defoliation plants showed up to 6 % and corresponding wine up to 24 % increase of the content of total anthocyanins as compared to the extracts from the control grape and corresponding wine samples. Partial early defoliation may be an excellent tool for control of anthocyanins in grapes and may be employed as a management practice as parameter for quality of red wines
