Authors: Libreros Cortez , Schrijver Iris
Published: December 2021

This qualitative article analyzes the advantages and challenges that Mexican university professors and students experienced with online translation teaching and learning during the August-December 2020 semester. Data was collected using online semi-structured interviews and non-participant observations involving 39 English language students and two translation professors from the School of Languages and Literatures of the Autonomous University of Queretaro. The findings show that some students could successfully manage distance education due to their organizational and self-learning skills, commitment, motivation, and proper internet access. However, most students faced various technological, didactical, and health issues that interfered with their learning process, which increased their desire to return to regular classes at the university as soon as possible.

Authors: Kreiner Jesa , Sajfert Dragana , Anđelić Svetlana , Jančev Nikola , Živković Milorad
Published: December 2021

In this paper, we analyze reliability, correlations, regression of employee obligations, compare employee regression, job satisfaction regression, and hierarchical regression analysis. As techniques for comparison of entrepreneurs and employees are significant for analysis of positive correlations between the determinants, we used 36 independent samples and 210 individuals. The findings reveal that: (1) The results of the research confirmed the existence of a statistically significant positive correlation between the determinants of job satisfaction and organizational commitment on one hand, and the work of entrepreneurs, on the other; (2) The results of the survey compare the relationship between entrepreneurs and employee job satisfaction and organizational commitment, adding a significant increase in the importance of the construct; (3) Entrepreneurship has a relative correlation in relation to job satisfaction, and organizational commitment, and thus increases the scope of tasks and efficiency of entrepreneurs; (4) Entrepreneurs show dominance over employee satisfaction and organizational commitment, when they predict the success of a group or organization and organizational civic behavior. We recommend that future researches examine the relationship among entrepreneurs and their relationship with employees, as well as job satisfaction and organizational commitment, in order to potentially compare them.
Interpreting relationships between pollutants and carbon dioxide emitted into air from industries in Serbia
Authors: Tutmez Bulent
Published: December 2021

The focus was on the pollution problem in Serbia and the relationships between CO2 emitted into air from industries and air quality indicators such as particulate matters (PM2.5, PM10), nitrogen and sulfur oxides (NOx, SOx), and volatile organic compounds were analyzed. To identify the dependencies, both parametric and nonparametric statistical learning-based evaluation algorithms were taken into consideration. Both the model structures produced satisfactory estimations with high accuracy levels. As a result of the model interpretation, PM2.5 has been recorded as the main indicator to explore the variability in CO2 concentrations. The implementations exhibited that interpretable machine learning can provide meta-data and sufficient information for making blackbox air quality system more explainable. Thus, the practiced modelling tools, the provided interrelationships as well as the new information could be considered by the national authorities within a computational environmental management strategy.

Published: December 2021

This paper is devoted to determining whether the addition of geological information can improve the resource estimate of mineral resources. The geochemical data used come from 116 drill holes in the Nkout East iron deposit in southern Cameroon. These geochemical data are modeled on Surpac and Isatis softwares to represent the 3D geochemical distribution of iron in the deposit. Statistical analysis and then a variographic study is performed to study the spatial variability of iron. Estimation domains were defined based on the results of geological and geochemical analyses. Four domains were determined. These domains are the saprolitic domain in particular; the poor domain or fresh rocks such as amphibolites, granites, and gneisses; the rich domain or oxidized rocks (BIF) and the metasediment domain. Block modeling of the deposit is performed to estimate the resource. The grade of each block was estimated by using ordinary kriging and composites from each domain. This study also consisted of comparing two types of estimate, notably the domain estimate and the global estimate. The cross-validation made it possible to authenticate the obtained models. From this comparison, the domain estimation brings more precision the global estimate precisely on the error analysis while if we take into account the point clouds of the predicted and estimated values, the estimation by geochemical modeling provides the best results.

Published: December 2021

Through this study special attention was paid to AMDs, originating from copper mines, containing different heavy metal ions, and a certain amount of sulphuric acid. The research was conducted on the territory encompassing the RTB Bor mines (now Serbia Zijin Bor Copper). The AMDs occurrences, their water composition, metal potential, and impact on the local surface waters were determined. The major amount of mine waters flow into the Krivelj River damaging extremely its water quality. The research also included monitoring the Timok river water quality along its course from the Krivelj River inflow to the confluence with the Danube. Evaluating the metal losses, it was found that every year around 360 tons of copper, >500 tons of iron, and 30 tons of zinc from mine waters are lost, as being transported via the Krivelj River to the Timok and then to the Danube.

The paper represents a part of research conducted with the aim of examining the possibility of applying selective flocculation of goethite from sludge that occurs in the process of iron ore production. The aim of this study was to compare the influence of polyacrylamide and sodium oleate as a flocculant on the settling behavior of goethite under different conditions. The paper presents the results of the research on the influence of the flocculants based on polyacrylamide and sodium oleate, as well as pH values on the settling rate of a natural goethite sample. The results showed that the settling rate of goethite was influenced by pH value and the type of flocculant, while the concentration of flocculant did not significantly affect the settling rate. Measurements of zeta potential showed the effect of flocculants on the surface of the goethite.
Hegel's totality as a necessary challenge for the possibility of achieving interculturalism: Polemical writings
Authors: Vukašinović Aleksa
Published: December 2021

The paper presents a polemical examination of the possibility of achieving interculturalism in the context of Hegel's totality, as the truth and the state of the modern world. In considering this problem, we start from the basic concepts of Hegel's philosophy of Spirit, with the aim of providing insight into the key problems of totality in the Hegel's philosophical system. The dialectical relationship that operates within the Hegel's system of Spirit is considered, and the question of the philosophy of history is opened as a specific way of thinking about historical movement that directs us to re-examine the possibility of achieving interculturality in the modern global society. Overcoming the current historical totality - global capitalism, requires a re-confrontation with Hegel's philosophy and setting of a dialectic that exists at the core of the world in which we live. Also, the paper offers an attempt to consider alternative actions, steps towards the realization of the idea and practice of interculturality and the development of a dialectical response to the perverted Hegelian totality that marks the present.
Duboka svest o istoriji Žan Rišara Bloka - jedna jugoslovenska epizoda
Authors: Mladenović Velimir
Published: December 2021

Francusko-srpski književni i kulturni odnosi često su proučavani na osnovu primarnih izvora, ali i na osnovu ličnog i profesionalnog odnosa umetnika i pisaca iz ove dve zemlje. Upravo ovakva istraživanja upotpunjuju istraživanja istoričara. Zato ćemo u našem radu ispitati odnos francuskog intelektualca, novinara i pisca Žan Rišara Bloka (1884-1947) prema srpskim i jugoslovenskim piscima i intelektualcima. Ovaj, danas nepravedno zaboravljeni, pisac rođen je i umro u Parizu. Učestvovao je aktivno u Prvom svetskom ratu, u kojem je ranjen čak tri puta. Nakon rata sarađivao je s francuskim listovima levičarske političke orijentacije. Godine 1921. pristupa francuskoj Komunističkoj partiji, a 1923. godine osniva čuveni književni mesečnik Evropa, koji i danas izlazi. S početka Drugog svetskog rata zbog svog jevrejskog porekla i političke orijentacije traži azil u SSSR-u. Tokom rata u Moskvi je radio kao radijski novinar i svakodnevno se obraćao Francuzima. U Francusku se vraća 1945. godine. Njegovu porodičnu kuću, s velikom bibliotekom, u naselju Merigo u Poatjeu Nemci nisu dirali, dok je stan njegove majke, koji se nalazio u centru grada, potpuno demoliran. U ratu ovaj pisac gubi više članova porodice. Analizirajući francusku i srpsku štampu, neobjavljenu arhivsku građu i reportaže ovog pisca, pokušaćemo da rekonstruišemo kako je Žan Rišar Blok bio prvi koji je stupio u kontakt sa srpskim đacima u Poatjeu i kako on za srpske intelektualce ostaje nepoznat sve do Španskog građanskog rata. Takođe, pokazaćemo i njegove aktivnosti u Jugoslaviji, njegov odnos prema jugoslovenskoj politici i kulturi, kao i učešće na prvom Kongresu jugoslovenskih pisaca. Budući da je kulturni transfer išao dvosmerno, u radu ćemo predstaviti i ne tako obimnu, ali svakako važnu, recepciju dva romana ovog autora I Kompanija i Španija, Španija! na jugoslovenskom prostoru. Upravo na taj način otvorićemo mogućnost da se i drugi istraživači zainteresuju za ovog intelektualca u kontekstu kulturnih odnosa Francuske i Srbije.
Life of the painting after death of the artist
Authors: Popovska Nataša
Published: December 2021

Following the path of the painting after the departure of Petar Lubarda, one of our most prominent art figures, we are faced with the question to what extent we have fulfilled our task to protect the cultural property that was left-donated-to us. Processing the data from the most extensive register in the documentation of the Faculty of Fine Arts, with a multitude of actual and sensationalist titles that follow the life of his paintings, we have learnt about the formation of a rich collection donated by the artist's wife, Vera Lubarda, to the City of Belgrade, about the opening of the Atelier of Petar Lubarda and, shortly afterwards, its closing and falling into oblivion. However, in the light of one century from the birth of our esteemed artist, a need arose for retrospective exhibitions, which have, along with marking the jubilee and forming the Legacy of Petar Lubarda, to some extent corrected the decades of neglect by the expert public and the responsible cultural institutions. With an objective approach to the preserved data recorded by numerous art historians, critics and journalists, which are kept in the Petar Lubarda files, the paper presents the most current events about the life of his paintings in the period from the artist's death to the present day

Accountability in the context of cooperative governance and local economic development (LED) in South African local government
Authors: Kamara Richard
Published: December 2021

Provided the tensions and challenges found in different types of governance systems for developing clear objectives, effective policy implementation strategies, as well as monitoring and reporting mechanisms aimed at improving efficiency and sustainability of initiatives, this paper seeks to contribute to both theoretical and practical debates surrounding cooperative governance and LED. Whilst better policy outcomes that fit with local and differentiated needs among stakeholders may be one of the drivers for moving towards cooperative governance, there is a normative question of accountability. Does the common feature of flexible and adaptable arrangements in cooperative governance create accountability deficit, specifically promoting laissez-faire approach commonly associated with the implementation among role-players? This paper considers this question and the extent to which accountability may be ensured. To address these concerns data were collected from six municipalities in Western Cape, South Africa. A qualitative research design paradigm based on Interpretivists/Constructivists philosophy was employed. Data were collected through three data collection instruments, namely, document review, interviews and focus group discussions. This paper argues that employing Key Performance Indicators as commonly used in the public service to promote accountability is difficult to enforce specifically in collaborative endeavors where participatory is voluntary. The paper recommends some accountability promotion enhancers. This will assist in improving the understanding of the context that may inhibit or enable stakeholders in taking full advantage of collaborative-led developmental interventions to further peoples' lives and to enhance their opportunities to partake in matters of development in their municipalities.
Media framing of human trafficking
Authors: Đukić Anđelija
Published: December 2021

In recent decades, there has been notably increased engagement of the international community in combating human trafficking, which has also been contributed by the media. The role of the media is reflected in building certain public attitudes and influencing political decision-making. Based on the selected literature, the paper considers the media framing of human trafficking from the 1990s to the present. The media decides on how to approach trafficking, content and causes, information sources, generating and presenting alternative solutions process, as well as motivational procedures for initiating actions of the public and politicians, thus creating diagnostic, prognostic and motivational frames. Based on the research, it is concluded that media frames of human trafficking are not holistic but segmental, and instead of a comprehensive approach, stereotypes are presented in which trafficking is identified with sexual exploitation or considered as the consequence of migration or organized crime actions. This harms the victims, makes the identification of all perpetrators difficult, and narrows the focus of the suppression efforts. It is noted that in the relations between the media, the public and the authorities, in the process of creating a policy and implementing solutions for combating, there are significant influences of policy-makers on media framing, and thus on public attitudes, which provides support and legitimacy of current or future political decisions. In order to illustrate the diversity of media representation of human trafficking, as a COM-plex phenomenon and the possibility of different analyses of media framing, the main findings of several studies in the USA, EU, and Serbia are presented.

Authors: Vitomir Jelena , Lazić Đorđe , Plakalović Novo
Published: December 2021

In the past decade the world faced the consequences of the global economic crisis proclaimed in 2008. The common case for everyone was a financial crisis in which every country bore the burden of the crisis in its own way, and in each country generators of the crisis appeared in different segments. In the 1980s American economist Hyman P. Minsky wrote about this topic, explaining the characteristics of financial crises in rigid financial systems. The aim of this paper is to understand the causes and the consequences of the crisis through creation, growth and bursting of the credit bubble in separate market segments in Bosnia and Herzegovina through the system of currency board. Through the application of vector autoregression model (VAR) the responses to shocks, recorded on the side of demand for loans which were generated in the capital markets and in the construction sector, and the credit shock of demand, which formed, developed and then exploded after the proclamation of the global economic crisis in Bosnia and Herzegovina, were analyzed. Interpretation of the results through the light of hypothesis of Minsky moment is corroborated by an additional fact that a rigid monetary system like currency board did not provide the necessary mechanisms for the maintenance of financial stability. Stability of the financial system of Bosnia and Herzegovina was saved exclusively by the will of parent banks from abroad whose daughters participate in the financial system of Bosnia and Herzegovina.

Authors: Radović-Marković Mirjana , Vučeković Miloš , Marković Dušan
Published: December 2021

The macroeconomic environment in the Western Balkans is based on the progress of the market economy and the development of the private sector. Strengthening the role of governance, education and social inclusion is crucial to improving countries' capacity for innovation, a stable financial environment, the successful implementation of broad-based reforms and the establishment of a macroeconomic environment that supports private sector activities. It is especially important to emphasize the importance of properly understanding the importance of scientific infrastructure in the field of research on the growth of "innovation capacity", so that national policies in this area can be formed. The analysis of the connection between innovation and globalization in the conditions of modern trends of economic development, showed that the reform momentum in the Western Balkans region has slowed down, which reflected that many of these economies have failed to use their potential for innovation.

Authors: Čelić Irena , Milićević Snežana , Đorđević Nataša
Published: December 2021

Having a qualified and trained workforce is an imperative for operating in the hotel management and tourism industry. Companies should show they care about their employees by giving them opportunities for promotion and development. The aim of this paper is to compare the staff training and development programs in the national hotels in Serbia with programs in international hotel chains. In order to achieve a predefined goal, we used the method of comparative analysis. Data for analysis were collected by researching the existing literature, the official hotel websites and interviewing managers in national hotels in Serbia. The results indicate that the staff training and development programs are more advanced in the international hotel chains. Management in the national hotels in Serbia is determined to follow different staff training and development programs. However, they should invest more in establishing more programs, especially those aimed at their staff's development which they can copy from the international hotel chains. The results of this research can be useful to hotel managers in the creation process of their own innovative staff training and development programs.
Financial analysis as a part of financial management reporting arising from internal audit recommendations in enterprises
Authors: Tomaš-Miskin Sonja
Published: December 2021

Financial analysis is part of the overall reporting, primarily financial management, and then top management in companies. The initiative to initiate financial analysis can come from the following parts of the broader management function of the company: internal controls, internal audits, top management, external audits, government agencies, shareholders, business owners and others. In this paper, the authors paid special attention to the importance of the initiative that originated from the company's internal auditors. In addition, the authors point out the importance of shaping and creating the very basis of financial analysis in companies in order to make a usable model of the proper functioning of reporting to the top management of a large number of companies. The aim of this paper is to show the advantages of properly setting up a financial management reporting system. In addition, proper top management reporting can contribute to creating better business results in the company.
The fight against corruption and social context
Authors: Mirevska Ivana
Published: December 2021

In this paper, the author tried to present the project of combating corruption in Serbia, starting from the theoretical definition and classification of this social phenomenon. Arguments are also provided proving that, in addition to good strategy and legal solutions, the effects in the fight against corruption also requires the establishment of a social climate in which zero tolerance for corruption will develop. The difficulty, on a global scale, is the fact that neoliberal capitalism encourages illegal activity, legitimizing it by the general rules of the free market. Bearing in mind that the provisions of the Law on the Anti-Corruption Agency also point to the prevention of corruption, the author has tried to answer the question to what extent the prevention designed here can prevent corruption, especially when it comes to those aspects that citizens in everyday life deal with most commonly encountered. The conclusion of this paper is that apart from suppressing corruption mechanisms, one should also take into account the general social situation that generates corruption - namely poverty and social insecurity, that is, suppression of corruption entails a much wider set of measures than anti-corruption laws.
Spoofing in civil aviation: Security and safety of GPS/GNSS and ADS-B systems
Authors: Kožović Dejan , Đurđević Dragan
Published: December 2021

Aircraft systems that rely on satellite positioning technology, such as GNSS and ADS-B, can be the target of a spoofing attack - a sophisticated and very dangerous form of radio frequency interference in which false signals are inserted into the "victim's" receiver for incorrect positioning or timing. Although spoofing in civil aviation is a potential threat, its technical feasibility is realistic, and the application of spoofing is becoming more flexible due to the very rapid progress of cheap SDR platforms. In particular, the potential risk is posed by potential air strikes, using unmanned aerial vehicles/drones, for the purpose of hijacking or distracting security in airspace surveillance. However, aviation is not ruthlessly exposed to spoofing attacks without any defense; by applying certain methods/techniques, spoofing can be mitigated in the GNSS receiver. Also, pilots are trained to detect and solve problems at every stage of the flight. Due to more sophisticated forms of terrorist attacks are possible, international organizations, such as ICAO and EUROCA, are proactively working to increase the robustness of the GNSS and ADS-B systems to spoofing. Given the importance of the topic and the fact that spoofing/antispuffing testing has certain limitations, consideration of the specifics and different scenarios of these attacks are very important in the development of new methods for their mitigation and detection. This paper focuses on spoofing/antispuffing of GNSS and ABS-B systems in civil aviation and provides an overview of the latest research in these areas.

Development and expansion of born global firms in Serbia
Authors: Rakita Branko , Mitić Sanja
Published: December 2021

Early internationalization has been widely recognized as an important research topic since 1990s when the term "born global firms" was for the first time introduced. Although there is significant research interest for early internationalization in developed and developing countries, in Serbia and Western Balkan this topic has not received considerable attention from the scientific community. At the same time, early internationalization of small and medium-sized firms is present and can not be neglected in the region and Serbia. This paper aims to identify the main prerequisites for the development of born global firms, and to identify and analyze small and medium-sized firms from Serbia with international business orientation from their founding. The analysis will be conducted based on literature review and available secondary data on small and medium-sized firms and their export. In this way, the early-internationalized small and medium-sized firms from Serbia will be mapped. As there are no available databases, this research will provide first insight into the extent of early internationalization and emergence of born global firms, and their characteristics, regarding industry, location, number of employees, business experience, and export expansion. The results would be discussed in regard to the studies conducted in developed countries. Some policy implications in the area of export promotion will be recognized.
Cognitive biases in marketing communication: Influence of anchoring and message framing on consumers' perception and willingness to purchase
Authors: Bunčić Svetlana , Krstić Jelena , Kostić-Stanković Milica
Published: December 2021

While in the theory of rational decision making, it is considered that people's choices remain consistent and predictable even in cases when same information is presented in different ways, in real situations consumers' decisions are affected by their personal characteristics, habits, norms and past experience, as well as limitations of human cognitive mechanisms. In general, heuristics can be perceived as fast cognitive processes in decision making which can sometimes lead to the occurrence of biases which shape the final decision. In marketing communication, the general capacity of people to make cognitive errors encourage the application of certain principles in formulation of messages in order to instigate recipients to make predictable cognitive errors when making decisions. The subject of the research is to determine how the encouragement of cognitive biase sin marketing communication can affect decisions of messages recipients. The research included the application of two research methods observation and experimental method. In as many as 80% of the observed advertisements, the encouragement of at least one cognitive bias was registered. In both experimental situations, it was shown that the willingness to pay for a product depends on the way the promotional message is formulated.
Commercial aspects of personal branding of athletes on social networks
Authors: Dašić Dejan , Ratković Milijanka , Pavlović Marko
Published: December 2021

The subject of this paper is the influence of social networks on the personal branding of athletes. The goal is to point out the importance of social networks in the process of personal branding of athletes. A responsible personality marketing management enables athletes to continue their successful careers even after the end of their engagement in sport. Social networks have an increasingly important role in this because they are also a measure of the influence of athletes, which can be quantified by the number of followers on social networks such as Facebook, Twitter, Instagram, etc. Some athletes earn more from their sponsorship agreements and activities on social network sin which they promote a certain brand than from professional contracts and salaries in their clubs. In the context of the topic of this paper, social networks can be viewed in two ways, as a means of improving the image of athletes, and as a tool that athletes use to promote brands. In the first case, the basic outcome is their higher commercial value, while in the second, the commercial effects are reflected in the earnings from brand promotion. This paper shows the connection between social networks, famous athletes, marketing tools applied in personal branding and commercial effects on that basis. The basic assumption that the commercial effects of personal branding of athletes can be successfully realized in the environment of social networks is confirmed.

In all modern countries, personal and corporate income tax are one of the safest sources of state budget revenue. The most significant direct taxes are personal income tax (tax) and corporate income tax.
Sino-Italian political and economic cooperation: Perspectives and challenges
Authors: Popović Slobodan
Published: December 2021

The purpose of this article is to examine Sino-Italian political and economic cooperation. The first part of the paper reviews the still ongoing process of China`s ambitions to present itself as a 'non-Other' to the international society by carrying out economic development and political opening and offering the Belt and Road Initiative to international partners. However, Beijing still faces (un)justified accusation that it affects the implementation of the already established norms, principles and procedures of the international law, sustainable development, geopolitical order, and geoeconomic distribution of wealth. For the purpose of this research, our focus will be on Italian understanding of the maritime perspective of the Belt and Road Initiative. The second part examines tools that the two countries use for overcoming obstacles to political and economic cooperation, whilst striving not just to widen and strengthen mutual trust, sincerity, and pragmatism, but to protect national interests as well.

Published: December 2021

A 5kg motorized Ginger rhizome (Zingiber Officinale Roscoe) peeling machine was designed, developed and tested. Three moisture contents (70%, 75% and 80% wb), three feed rates (54 kg/h, 68 kg/h and 73 kg/h) and three peeling speeds (230 rpm, 270 rpm and 300 rpm) were used for the performance evaluation of the machine. A 3 × 3 × 3 factorial experiment in a randomized complete block design (RCBD); replicated two times was used to study the effects and interactions of the three factors (moisture content, feed rates and peeling speed) on the performance parameters (peeling efficiency, peeling capacity and percent damage). Relationship between performance parameters and the influencing factors were determined using multilevel factorial design and response surface methodology for the graphical analyses. The study showed that peeling efficiency increased from 82.3% to 88.5% with an increase in moisture content from 70% to 80%, a decrease in feed rate from 73 kg/h to 54 kg/h and an increase in peeling speed from 230 rpm to 300 rpm. Peeling capacity increased from 2.4 kg/h to 11.64 kg/h with an increase in moisture content from 70% to 80%, a decrease in feed rate from 73 kg/h to 54 kg/h and an increase in peeling speed from 230 rpmto300 rpm. Percent damage increased from 6.3% to 14.4% with a decrease in moisture content from 80% to 70%, an increase in feed rate from 54 kg/h to 73 kg/h and an increase in peeling speed from 230 rpm to 300 rpm. The analysis of variance (ANOVA) result showed that the interaction of moisture content, feed rate and peeling speed had significant effect on peeling efficiency, peeling capacity and percent damage at p<0.05 level. For a maximum peeling efficiency, peeling capacity and minimum percent damage, an optimum moisture content of 75%, feed rate of 68 kg/h and peeling speed of 270 rpm were recommended for use.

Applying mass balance dilution technique for wastewater disposal to Greater-Zab river in Erbil, Kurdistan region-Iraq
Authors: Aziz Shuokr , Bruska Sardar
Published: December 2021

Treatment is essential for wastewaters prior to its disposal to the environment or water sources. Numerous wastewater treatment techniques are applied for the treatment of wastewater types. To date, dilution via mass balance approach has not been reported for treatment of various types of wastewaters in Erbil City, Kurdistan Region-Iraq. Consequently, the aim of this work was to examine the treatment of various types of wastewaters using dilution method by river water through applying mass balance approach. Characteristics of different types of wastewaters and Greater-Zab River water in Erbil City were studied. Slaughterhouse, tannery, municipal, landfill-leachate, dairy, and refinery wastewaters in Erbil City were used in the present work. Mass balance approach was applied to verify that dilution of various types of wastewaters using Greater-Zab river water. Dilution factor and required amount of river water were calculated. Temperature, biochemical oxygen demand (BOD), and Dissolved oxygen (DO) were studied using mass balance approach. Results revealed that dilution factor for Erbil wastewaters varied from 10.36 to 513.91. Mixing of wastewaters with Greater-Zab river water led to decreasing of DO in the river water by 3.525 % and increasing of BOD in the Greater-Zab River water. Dilution using various quantities of raw river water via applying mass balance approach resulted in decreasing the pollutants in the wastewaters to an acceptable level and it was regarded as a treatment process. Each type of wastewater needs a definite quantity of raw water for the treatment. Commonly, sedimentation is suggested prior dilution of wastewater with the Greater-Zab River water. Maximum discharge of 1,182 m3/s is sufficient for treatment of all mentioned types of wastewaters in Erbil City.

Authors: Miltojević Vesna , Ilić-Krstić Ivana , Orlić Anđelija
Published: December 2021

Burnout is associated with long-term exposure to workplace stress and it comprises exhaustion, cynicism, and the feeling of inadequacy as its dimensions. University students are exposed to a variety of stress-inducing factors during their studies regardless of the fact that they are not employees. The aim of this study is to examine the relations between specific sociodemographic variables and burnout dimensions among students of master academic studies. School Burnout Inventory (SBI-U 9) is used as the research instrument. The obtained results indicate that there is a connection between students' gender and tuition fee status and burnout. Gender is associated with exhaustion and the feeling of inadequacy, while tuition fee status affects all three dimensions.
Nitrosamines: Carcinogenic chemical 'intruders' in occupational environments
Authors: Miltojević Ana , Golubović Tatjana , Stojanović Marina
Published: December 2021

Nitrosamines, or more precisely N-nitrosamines, along with N-nitrosamides, belongs to N-nitroso compounds, a class of organic compounds that have a nitroso (-N=O) group attached directly to a nitrogen atom. Only a few of them occur naturally while the majority is formed by nitrosation of secondary amines in a living and working environment, food, tobacco smoke, etc. These compounds have scarce application in the industry, but they can be formed in situ, so they can be considered as chemical intruders in working environments. Considering their toxicity, especially carcinogenicity, where there is a risk of exposure to N-nitroso compounds, appropriate protection measures should be taken, including process control, work practices, protective clothing, use of respirators, legal regulations.
An overview of 1998 versus 2020 edition of Guidelines for Limiting Exposure to electromagnetic fields
Authors: Gavrilov Teodora , Đurić Nikola , Kljajić Dragan
Published: December 2021

One of the most important documents defining recommendations for limiting exposure to almost inevitable electromagnetic radiation was released in 1998 by International Commission on Non-Ionizing Radiation Protection (ICNIRP). This document is "Guidelines for Limiting Exposure to Time-varying Electric, Magnetic and Electromagnetic Fields (up to 300 GHz)". However, the growing knowledge about the electromagnetic field (EMF)-tissue interaction and appearance of innovative telecommunication technologies, raised the need for the improvement of these Guidelines. Thus, the ICNIRP published the latest version of its recommendations in 2020. The purpose of this paper is to briefly present some important differences between the ICNIRP 1998 and 2020 Guidelines and to enlighten their reflection on national EMF legislation.

Published: December 2021

Introduction: Celiac disease is an autoimmune disease caused by an inadequate immune response in contact with gluten in genetically predisposed individuals. Barriers to maintaining a strict gluten-free diet arise due to several factors, the most common of which are: inadequate information, insufficient education about the disease, food contamination. Aim of the research: To determine the ways of informing parents about the celiac disease that has been diagnosed in their children, as well as to learn about the necessary procedures to improve information about gluten-free diet. Subjects and method: The study included a sample of 116 parents whose children are diagnosed with celiac disease and who are on a gluten-free diet. The place of research is the Institute for Maternal and Child Health of Serbia "Dr Vukan Cupic" in New Belgrade and the University Children's Clinic in Belgrade. The research instrument used is the Questionnaire on Parents' Awareness of Celiac Disease, which was created for the purposes of this research. Results with discussion: The results of the study show that 47.14% of parents of children with celiac disease ask for information about the proper nutrition of their children and gluten-free foods from the doctor of the institution where the child was diagnosed with the disease. In order to better understand the diagnosis of celiac disease in their child, 53.01% of parents most often chose to talk to the doctor who treats the child. Conclusion: Information on proper nutrition of children and gluten-free foods, as well as specific information on celiac disease, is requested from the doctor of the institution where the disease was diagnosed in the child and where they go for check-ups. Many complications caused by unrecognized celiac disease could be prevented by timely diagnosis and proper posture of the child, which contributes to good and adequate information.
