African Swine Fever Outbreak Investigation on Large Commercial Pig Farm in Serbia

Abstract The first confirmed case of African Swine Fever (ASF) in Serbia occurred in 2019. Since then, numerous outbreaks in domestic pigs and wild boars have been reported. Until April 2021, all the detected ASF cases were in backyard pigs. Beside backyard and smallholders farming systems as a dominant pig production system in Serbia, large commercial pig farms can also be found, located mostly in villages. In the beginning of April 2021, a large commercial farrow-to-finish pig farm in Serbia with almost 19,000 animals was affected with the ASF virus. The pig farm analysed in this paper is located in an area where ASF was confirmed earlier in both backyard and wild boars. In this study, we describe the overall epidemiological course of the ASF outbreak. Epidemiological investigation using a hypothesis-based approach was conducted in order to reconstruct the disease course until the official notification. All the available data from the farm were analysed with the aim to determine the high-risk period (HRP). Some of the key points to consider when it comes to the sources of infection and entry route of ASF are the following: contamination of the area in the immediate vicinity of the farm, risky human activities, irregularities and some omissions in the external farm biosecurity and immediate proximity of the city waste-yard where the communal waste is disposed of. It was concluded that when commercial pig farms are surrounded by villages with a large number of backyards, hence the anthropogenic factor is the key risk factor for ASF spreading.

State and perspective of individual household heating in Serbia: A survey-based study

This paper presents the results of the household survey on individual household heating systems in Serbia. The survey was conducted in the period October to December 2020 with the participation of 1100 households with individual household heating systems. The information collected in the questionnaire can be separated into three main parts: basic household data, current heating system characteristics, and households’ perceptions and attitudes. The survey results provide unique and comprehensive information concerning individual household heating systems and the main barriers and drivers for a successful energy transition in the future. The results show the obsolescence of household heating systems, low efficiency, insufficient investment in thermal insulation in the past, and lack of financial resources for investing in sustainable heating. On the other hand, this survey highlights the positive attitude of about half of households towards potential subsidizing of the cost of new heating systems. This survey presents a valid starting point for defining instruments aimed to improve energy efficiency in the household sector, diminish its influence on climate change, and secure energy transition towards sustainable heating systems. The obtained results should be indicative for middle-income developing countries at the beginning of the energy transition process.

Does a National Innovation System Encourage Sustainability? Lessons from the Construction Industry in Serbia

Influences from the modern business environment indicate the need for the incorporation of sustainability concepts from an innovation system perspective. In the presented research, we emphasize the energy efficiency concept within the frame of sustainability and innovation. The aim of this research was to underline and explore the relationships between innovation, energy efficiency, and sustainability in the construction industry. To answer the research questions, a questionnaire was created to explore the impact of the energy efficiency certification process on the innovation behavior of construction industry enterprises in Serbia. The results show that energy efficiency has supported innovation, and that there exists a relationship between sustainability and innovativeness in the construction industry. Applying energy efficiency passports has influenced the co-operation of enterprises in the construction sector and other actors in the national innovation system in Serbia. The innovation concept demonstrates that enterprises in the construction industry should be observed as a part of the wider picture—the national innovation system. In turn, the specific context of a particular national innovation system should be seen within the wider picture of national innovation systems of Central and Eastern European Countries (CEECs).

Utilizing sewage wastewater heat in district heating systems in Serbia: effects on sustainability

Transformation of the heating sector is recognized as being essential for ensuring reliable and affordable energy services provided with reduced consumption of energy sources and diminished impact on the environment and less import dependency. The possibility of utilizing energy sources that otherwise would be wasted needs to be considered and treated as a big advantage of district heating systems. Despite many advantages, sewage wastewater heat is still a mostly unused resource at the global level and a totally unused energy source in Serbia, while data about the potential of this energy source are lacking. This research proposes a methodology for the determination of the technical potential of waste heat from wastewater treatment facilities for use in district heating systems by heat pump application. Data from existing wastewater treatment facilities are used for providing data for replication in cities without wastewater treatment plants but with district heating systems. An estimation of the recoverable heat energy potential of wastewater is used for evaluation of some effects that could be obtained through its full utilization for heat production in the existing district heating systems. Three groups of indicators are selected for analysis focusing on district heating systems' energy performance (primary energy factor, specific heat consumption per degree day and heating area), the security of energy supply (import dependency, Shannon–Wiener diversification index, the share of renewables) and environmental impact (carbon dioxide emission coefficient). Values of the selected indicators are determined for the current state of district heating systems and for the possible future state that could be achieved after full utilization of sewage wastewater potential. The proposed methodology is applied to Serbia, as a case study. It has been shown that all analyzed indicators for the projected future would have more preferable values compared to the values that correspond to the current state of the district heating systems. The use of this renewable energy source should provide primary energy savings of 5% per year, reduction of carbon dioxide emission of 6.5% per year, reduction of import dependency of DH systems of 9.8% and improved diversification of energy sources of 21%.

Control theory-based data assimilation for hydraulic models as a decision support tool for hydropower systems: sequential, multi-metric tuning of the controllers

Abstract Increasing renewable energy usage puts extra pressure on decision-making in river hydropower systems. Decision support tools are used for near-future forecasting of the water available. Model-driven forecasting used for river state estimation often provides bad results due to numerous uncertainties. False inflows and poor initialization are some of the uncertainty sources. To overcome this, standard data assimilation (DA) techniques (e.g., ensemble Kalman filter) are used, which are not always applicable in real systems. This paper presents further insight into the novel, tailor-made model update algorithm based on control theory. According to water-level measurements over the system, the model is controlled and continuously updated using proportional–integrative–derivative (PID) controller(s). Implementation of the PID controllers requires the controllers’ parameters estimation (tuning). This research deals with this task by presenting sequential, multi-metric procedure, applicable for controllers’ initial tuning. The proposed tuning method is tested on the Iron Gate hydropower system in Serbia, showing satisfying results.

UČENJE NA DALJINU IZ UGLA NASTAVNIKA, UČENIKA I RODITELJA

Uvođenjem vanrednog stanja u Srbiji usled epidemiološke situacije u zemlji, obustavljen je neposredni obrazovno-vaspitni rad u školama, a nastavak obrazovanja obezbeđen je kroz učenje na daljinu. Ministarstvo prosvete, nauke i tehnološkog razvoja organizovalo je edukativne emisije na televiziji, dok su škole dobile zadatak da nađu načine za komunikaciju na daljinu sa svojim učenicima i da im, pored postojećih edukativnih emisija, pružaju podršku u učenju. Budući da učenje na daljinu do sada nije bilo u većoj meri zastupljeno u obrazovnom sistemu u Srbiji, naročito kada je u pitanju osnovno obrazovanje i vaspitanje, namera ovog istraživanja je bila da utvrdi kako je započelo učenje na daljinu, koji kanali komunikacije sa učenicima su uspostavljeni i šta učenici i njihovi roditelji misle o ovakvom načinu rada. Rezultati pokazuju da je većina nastavnika i učenika uspostavila adekvatne kanale komunikacije, da su učenici aktivno uključeni u učenje na daljinu, ali i da su podeljena mišljenja o opterećenosti učenika sadržajima i načinom rada. Na osnovu dobijenih rezultata, kreiran je set preporuka za unapređivanje nastave na daljinu u trenutnoj situaciji. Takođe, nameće se pitanje na koji način, po normalizaciji uslova i povratku učenika u škole, uvrstiti učenje na daljinu u redovan obrazovno-vaspitni rad.

Social space of preschool institutions as a factor of gender equality

The subject of this paper is a sociological gender-sensitive analysis of the use-value of space in public preschool institutions (PPI), starting from the level of Serbian society, through Belgrade and Belgrade municipalities, down to the level of individual kindergartens. The objective of the research is to design the space of PPI facilities, which would provide the families and mothers with control over public space, and thus meet one of the preconditions for positive structural change - gender equality. The following parameters are used as indicators of the use-value of DPU space: the position of the preschool system in Serbia, coverage of children in the preschool system and preschool institutions by type of ownership, coverage of DPU children, insufficiency of DPU social space in Belgrade, compliance of available space in DPU municipalities Cukarica and Vozdovac with valid norms). Data sources: institutional data research (survey research ?Spatial capacity of preschool institutions in Belgrade?, conducted at the Faculty of Geography, Department of Spatial Planning, on the subject of Social Development Planning, 2018-2019). The main results of this research confirm the presumed issue in this field, which causes the unequal gender power relations and various consequences which affect the position and quality of life of women-mothers and men. The preschool system in Serbia is in an unfavourable position due to the serious insufficiency of PPI facilities in Belgrade (out of a total of 124,846 preschool children, there is enough space for less than one half; the analysis of the existing PPI capacity shows that there are large differences in capacity at the municipal level, from about three quarters to about one quarter,) and at the level of Belgrade municipalities. The data available for the municipalities of Cukarica, Vozdovac, Palilula, Zemun, Zvezdara, and Novi Beograd show that the same problem exists there as well, which can be solved by accepting the proposals for the required capacity of public kindergartens, which are given in this paper. The insufficient PPI capacity in the municipalities of Cukarica and Vozdovac has been documented at the kindergarten level (a total of 55, 22 of which in the municipality of Cukarica, and 33 in the municipality of Vozdovac.

Smart Manufacturing as a framework for Smart Mining

Based on the analogy between manufacturing and mining (i.e. ore ‘production’), smart mining has four dimensions: (i) advanced digital-oriented technologies (such as Cloud computing and the Internet of things) with automated Cyber-Physical Systems (CPSs), adaptable production processes (dependent on working conditions) and production volume control (with optimal resource consumption); (ii) smart maintenance of CPSs; (iii) new ways for workers to perform their activities, using advanced digital-oriented technologies; and (iv) smart supply-chain (procurement of materials and spare parts / products delivery). This paper presents a case study on the smart mining approach implemented at a coal mining system in Serbia.

Pravo etažnih vlasnika na zemljištu na kome se zgrada nalazi u kontekstu pretvaranja prava korišćenja u pravo svojine na građevinskom zemljištu

Initially the paper recalls that the apartment/condominium ownership is a complex legal construct, which, as a special form of ownership, is the legal institute of modern age. Thereupon, the reasons underlying its legal recognition and widespread use have been indicated, taking into account its deviations from the general ownership regime. Complexity of the apartment/condominium ownership stems from its specific object. Namely, three components of this legal construct: the right on the separate unite of the building (which could be in the the exclusive ownership, co-ownership or in joint ownership), the right on the joint parts of the building (in joint ownership of apartment owners), and the right on the land on which the building is located (in co-ownership of apartment owners), should be normatively shaped and systematically coordinated. Special attention has been paid to the right on the land, from the viewpoint of its peculiarity during the development of a legal system in Serbia after the World War II. The process of conversion, i.e. transformation of the right of use into the right of ownership in Serbia has begun in 2009 by entering into force of the still applicable Planning and Building Act. Evolution of the regulation of the rights of apartment/condominium owners on the land on which the building was erected (including the land which serves for its regular use), from 2009 to 2020, has been examined in detail in the light of its adequacy and capacity to contribute to the (re)establishing of the legal unity of the immovable property, as well as to the prevention of contentious situations.

Ka kritičko-refleksivnom planeru - prilog unapređenju prakse na primeru kompleksa "Avala filma"

The aim of this paper is to illustrate the results of the pedagogical approach that was created to develop the competencies of a critical and reflective professional. The pedagogical approach was developed for the master's level Planning Theory course at the Faculty of Architecture, University of Belgrade. The specifics of the pedagogical approach stemmed from the need to consider a number of new issues relevant to improving planning practices, planning systems and the domain of spatial development in Serbia, which have emerged during the period of transitional reforms in Serbia since 2000. The case of preparing the plan of detailed regulation for the Avala Film complex in Kosutnjak, which was also the subject of the work of students in the school year 2020/21, was taken as a testing ground to illustrate the approach. The methodological steps in the analysis of the case clearly indicated the following problems in the field of spatial development: a) urban plans serve as an instrument for the alienation of publicly owned land, b) public policies are selectively considered in the decision-making process on spatial development, c) formal planning procedures are insufficiently clear and have gaps in formulations, which creates space for ambiguous interpretations, d) decision-making positions on strategic development priorities and issues of public interest are not clearly defined and e) key issues on spatial development are resolved in the domain of political rather than professional decision-making. Based on the analysis of the planning process for the Avala Film complex, recommendations for improving planning practice, i.e. the spatial governance system in Serbia are made. They are essentially aimed at improving the legislative system in the decision-making process, with an emphasis on formalizing positions of competence, determining mechanisms for the alienation of public property, improving the transparency of procedures and re-positioning the role of the profession in that process.

The experiences and expectations of returnees to Serbia during the COVID-19 pandemic

This article discusses the experiences of Serbian citizens who came back to their country of origin just before or at the onset of the COVID-19 pandemic and the introduction of the state of emergency. We analysed their motives to return and their experiences during self-isolation. We also highlighted the problems they encountered at the beginning of the pandemic and the impact they had expected the pandemic would have on their social and economic status. The paper covers their plans for mobility after the end of pandemic, as well as potential motives for staying in Serbia. The aim is to show that even though a large number of citizens came back to Serbia when the crisis broke out and could not have predicted what would happen to their social and economic status in their destination countries, they still did not intend to stay in Serbia after the end of the pandemic. The whole social system in Serbia would need to be changed for them to decide to stay. Discussion of the results is based on data collected at the beginning of pandemic by researchers from the Institute of Sociological Research, one of whom was the author of this paper. Due to the health risks related to the coronavirus, we used a quantitative method: a questionnaire distributed online via the Google platform. As such, the respondents were mostly young and educated people who took part in the research because they used the internet on a daily basis and were able to fill in the survey easily. For this reason, the results presented in this article cannot be generalised to represent the whole population, but only the respondents of this research. The findings are placed within a contextual framework in which the world?s population is extremely mobile. We recognised a similarly high level of mobility among Serbian citizens, too. The COVID-19 pandemic has affected many different aspects of life, and so a large share of respondents decided to come back to their home country. This was a normal coping strategy, especially for those migrants who did not have officially recognised status in their destination country. Returnees faced many problems when they returned to their home country; they had to self-isolate and did not know what would happen with their jobs once the pandemic was over. They also didn?t know if they would receive an income or what would happen with the social system, either in their home country or in their country of emigration. Analysis of the data revealed that despite their expectations of an economic crisis following the drastic measures introduced to suppress the spread of the coronavirus, a large share of respondents believed that the crisis wouldn?t have an impact on their material and social status in their destination country. Because of that, we noted that most respondents wished to go back to their destination country after the crisis was over. However, it?s suggested that if we want them to stay in Serbia, then the state should introduce measures that include both economic and social reforms.

THE ROLE OF DISTANCE LEARNING DURING THE COVID-19 PANDEMIC

<jats:p>The primary objective of this paper is to present the analysis of the functioning of distance learning in the educational system in Serbia during Covid-19 pandemic, and to draw conclusions on the readiness of the system for such and similar situations. More specific, the objective is to consider the role of distance learning in these circumstances, bearing in mind the fact that only in primary and secondary schools nearly 750,000 students and some 80,000 teachers were forced to use one or the other distance learning method. COVID-19 pandemics has affected educational systems in Serbia and worldwide alike, posing unimaginable logistic and technological challenges, forcing teachers to teach in new and unfamiliar ways. The paper first provides an overview of the most commonly used distance learning platforms and applications, in general and especially during a pandemic. In particular, research was conducted on students' attitudes about distance learning during the pandemic. The data obtained from a survey conducted at the Faculty of Economics, University of Belgrade is also analysed. The paper points out that the impact of the pandemic will clearly be far-reaching and widespread, raising the issue of its possible long-term significance for the education in general, and the educational system in Serbia in particular. The paper also points to the need of generation of new ICT skills in education. Technology has taken roots in education and will continue to play the key role in educating generations to come. With knowledge just a click away, the role of teachers will inevitably change.</jats:p>

Operators' visual angles, the distance between the operator's eyes and display panels, the size of visual signs, comparative analysis of display panel and video display units used in the control room are given. The main goal of this paper is to apply the result obtained in designing a new control room in Serbia since the adequate design of display systems in control rooms has a significant impact on the efficiency and functionality of the operator's work in control centers.

Changes in Work Orientations in Postsocialist Serbia

AbstractThe subject of this study is work orientations, their change over time, as well as their distribution among the economically active citizens of Serbia. Particular attention is paid to work-motivated spatial mobility. The aim of this study is twofold: firstly, to determine which work orientations have been the most important for economically active individuals in the period of consolidation of the capitalist system in Serbia and to explore and explain the changes in their choices that have occurred since 2000; and secondly, to examine whether there are differences in prioritizing work orientations among actors with various social characteristics. The method of comparative analysis used in this paper was possible due to survey data collected during longitudinal research conducted by the Institute for Sociological Research in Belgrade over the last twenty years.

Disease burden of edentulism – Dental Clinic of Vojvodina, Serbia, 2008-2019

Abstract Background Although there is a decline in the global prevalence of edentulism over the past decade, the tendency is opposite in Serbia. The aim of this study was to estimate the disease burden of edentulism at the Dental Clinic of Vojvodina, tertiary referral public health institution of the northern province of Serbia. Methods Disease burden was expressed in disability-adjusted life years (DALYs). Prevalence (P) was calculated on the database of all patients from 2008 to 2019 at the Dental Clinic of Vojvodina using IBM SPSS Statistics. The number of diagnosed cases rehabilitated by complete dentures was an indicator of edentate people. A total sample of 76287 patients was examined, including 1620 patients restored with complete dentures (44.94% male, 55.06% female). Disability weight (DW) for severe tooth loss was taken from the “Disability weight for the Global Burden of Disease 2013 study”. The prevalence-based years lived with disability (YLD) were calculated as YLD = P x DW. Due to the non-fatal outcome of edentulism, DALY estimates were based on YLDs only (YLL=0). Results For the observed period, the total disease burden (per 1000) was 1.42 DALYs (0.64 for men and 0.78 for women). During observed years, DALYs increased (from 1.66 in 2008 to 1.73 in 2019), in association with population aging, and insufficient support from public health insurance for oral prevention and treatments. For both sexes, DALYs increased gradually with age. The results for age-stratified DALYs (per 1000) were: 0.005 (age 0-24), 0.049 (age 25-34), 0.55 (age 35-44), 2.66 (age 45-54), 4.41 (age 55-64), 7.89 (age 65-74), 8.04 (age 75-84) and 9.05 (age 85-94). Conclusions Considering the calculated disease burden, edentulism has been posing an increasing challenge for the health system in Serbia over the past decade. The quantified burden could contribute to the improvement of evidence-informed policymaking in public oral health in Serbia. Acknowledgment Supported by “Burden-EU” COST Action Key messages The calculated DALYs show an increase in burden of edentulism in Vojvodina, Serbia. DALYs calculations could improve the insufficient monitoring of oral health status in Serbia.

SOME ASPECTS OF REFORM AND CHANGE IN THE SYSTEM OF SECONDARY MUSIC SCHOOLS - ANALYSIS OF RELEVANT LITERATURE

The paper debates some aspects of reform and change in secondary music education. The reforms in secondary music education are in line with the general tendencies in the school system in Serbia. Accordingly, the paper discusses the leading aspects of the changes in the secondary music schools and their alignment with similar schools in the European educational system.The main objective of this theoretical research is to identify significant aspects of changes related to curriculum change and innovation in content - textbooks, and the assessment process. The paper uses a qualitative approach, based on an analysis of selected research studies published after 2001. They cover key topics related to changes in secondary music schools. In spite of the fact that there are few research papers in our region that deal with the implications of the reform in the secondary music education system, based on the analysis of the available papers we can conclude, that there are steps to meet the planned changes.

Constitutional Court as Constitutional Complaint Institution: Evidence from Serbia

Abstract A noticeable increase in the scope of powers of the constitutional supervisory body of Serbia is directly related with a qualitative change in the status of the Constitutional Court. The purpose of the article is to analyse the competences of the Constitutional Court of the Republic of Serbia in protecting rights and freedoms as the most important area of its activity. The article presents a study of the increased powers of the Constitutional Court of the Republic of Serbia, the purpose of which is to protect rights and freedoms. The leading method in this study is the system analysis method, which allows us to assess the significance of the constitutional complaints institution in Serbia. Studying the current regulation of the competence of the Constitutional Court of Serbia, the author concludes that the significantly expanded competence of the Constitutional Court of Serbia fully reflects its status as a constitutional body representing the fourth judicial control authority in the state. It also ensures the supremacy of the Constitution and protects the foundations of the constitutional system of Serbia, including protection of rights and freedoms in the Republic of Serbia.

Students’ attitudes towards sustainable development in Serbia

PurposeThe purpose of this paper is to examine university students’ attitudes towards the concept of sustainable development and towards the need for the implementation of education for sustainable development into the higher education system. To that end, the paper explores in a process-oriented focus which drivers and barriers are experienced as being the most important ones and how they relate to one another.Design/methodology/approachThe study is based on the questionnaire for the evaluation of attitudes towards the concept of sustainable development. This instrument consists of 9 batteries with 83 items presented in the form of the five-point Likert scale. The questionnaire evaluated different aspects of respondents’ attitudes towards the concept of sustainable development, but students’ attitudes in relation to the items from the following subscales will be presented for this paper: understanding the concept of sustainable development, position of sustainable development in the system of higher education, sources of information about sustainable development and entities responsible for sustainable development. The study sample consisted of students from the University of Novi Sad, specifically from the faculties with accredited programs in the field of humanities and technological sciences.FindingsIn general, students recognized the main determinants of sustainable development and they support an integral approach to sustainability, i.e. the need to include the knowledge, values and skills for sustainable development in the higher education programs. In addition, they identified a number of obstacles and the uncertainties of overcoming them. In this regard, the students did not recognize the responsibility of the higher education institutions as the key responsibility or their own responsibility in relation to sustainable development, which can be related to their feeling of marginalization and the doubt that their behaviour and decisions can influence the development of the local society, as well as the development of the society as a whole. On the other hand, the respondents acknowledged the role, the importance and the responsibility of the mass media in the process of developing the attitudes towards and opinions about the problems related to environmental protection and sustainable development.Practical implicationsThe results of the study indicate the students’ attitudes towards sustainable development, thus making the directions for higher education reform clearer and in line with the present needs for sustainable development in Serbia. The obtained results can serve as a recommendation to the governing structures, i.e. to the relevant ministries of education and environmental protection, as well as to the universities in terms of which direction their process of planning and creating paths of sustainability should take. This is particularly important in the case of the Republic of Serbia, which is currently in the process of joining the European Union and responding to the requirements set by the process of negotiation for Chapter 27 in terms of improving the strategic framework and plans for the education for sustainable development and building the capacities in response to climate change. On the other hand, linking the results of this research with the results of similar studies around the world contributes to the further enrichment of the scientific knowledge base in this field and confirms the need for stronger and united efforts on the path to a sustainable future. It is a fact that, regardless of the national, economic, socio-political and cultural context, there is a global lack of success in shaping a humane and sustainable relationship between man and nature. Therefore, the results of this research should be considered as an invitation for new research initiatives regarding the ways to support the positive attitudes of students towards the concept of sustainable development and to facilitate their further development in the educational process, as well as in other academic domains.Originality/valueThis research is inspired by the fact that, in the Balkan countries, education for sustainable development has not been extensively discussed within the scientific discourse on higher education for sustainable development. This is one of the first papers to provide data about students’ attitudes towards the concept of sustainable development and the need for its implementation in the higher education system in Serbia. The value of the paper lies in its potential to help understand the role that different drivers and barriers play in higher education for sustainable development.

Analysis of fresh and processed carrots and beets from organic and conventional production for the content of nutrients and antioxidant activity

In order to popularise organically produced vegetables, two vegetable crops most commonly grown in organic systems in Serbia were studied. This research aimed at investigating differences in phytonutrient content between organically and conventionally produced beet and carrot, in fresh roots, juices pasteurised at different temperatures (70 and 90oC) and dried products. Multivariate analysis (principal component analysis) was used in order to determine the main components accounting for the highest variance, from both systems of production, according to the average content of phytonutrients in beet and carrot. The samples were divided into two clusters, one for carrot and one for beet, each containing two subgroups. The subclusters for beet were: I - BDO, BDC, BJ90C, and BJ90O - dried samples and juices pasteurised at 90oC, from both systems of production; and II - BFC, BFO, BJ70O and BJ70C - fresh beet and pasteurisation at low temperatures. The two sub-clusters for carrot were: I - CDO and CDC - dried samples; and II - pasteurised juices and fresh carrots from both systems of production. In this research, carrot was more stable for processing than beet, as determined for samples from the study area, from both systems of production and for the phytonutrients covered by this research.
