Three edible mushrooms of the Russulacea family (Lactarius deliciosus, Lactarius sanguifluus and Lactarius semisanguifluus), most frequently consumed in Serbia, were analyzed using the ICP-OES technique to evaluate the content of K, P, Ca, Mg, Na, Al, As, Cd and Pb, both in cap and stipe. Corresponding soils were analyzed, too. Based on the obtained values for the elemental composition of the mushrooms and the soil, bioaccumulation and translocation factors were calculated. All the examined mushrooms species were recognized as bioexclusors of analyzed toxic elements, but bioaccumulators of K, P and Ca. The studied mushrooms are good sources of macroelements. One portion of 300 g of fresh mushrooms had a significant contribution of K and P, exceeding 15 % of the recommended daily intake for the elements. On the contrary, mushrooms had a low potential to bioaccumulate toxic elements, and presented results indicated the regular consumption of wild edible mushrooms is safe for human health. Correlation analysis was applied to determine phosphorus’s influence on the elements’ content in the mushrooms and corresponding soils, demonstrating the most remarkable mushrooms' tendency to accumulate phosphorus.

Innovations are the key to the long-term survival, growth, and development of any organization. For that reason, all organizations strive to have as much as possible successful innovations that consequently bring many positive effects to the entire economy. This paper points out the importance and role of engaged employees who take a leading role in organizational innovations. Engaged employees give their best effort during the performance of work tasks, try to create new, better ways to perform certain activities through cooperation and exchange of knowledge with colleagues, and try to improve the functioning of the entire organization. With their enthusiasm, perseverance, persistence, and sincere desire to give their contribution to the business of the organization, engaged employees are the important source of creativity and innovation in the workplace. At the organizational level, a significant role in the innovation process has the proposals of engaged employees who truly love their job, the organization in which they work and have the desire to dedicate themselves to additional innovative activities that are not in their job descriptions.

In the newly created unusual circumstances, what follows is a transformation of three principles of a visual merchandising from real to virtual experience of visual, tactile (emotional) perception of the customer, balanced offer and freedom of choices. Finding and adopting new methods of visual merchandising and models of communication aim to, globally, give fashion brands efficient and fast access to each individual and can enter into a virtual dialogic form with them, providing virtual vision, tactility and emotion so that the potential buyer would be an active participant and make a certain choice.

Every organization strives to have productive, creative, responsible employees, who constantly seek to acquire new knowledge and skills, who are motivated, loyal and engaged, and psycho-physically healthy. However, modern and dynamic business conditions, constantly growing demands and needs of consumers, setting new goals and tasks, increasing the level of responsibility and standards, and often setting expectations from employees too high are just some of the many pressures and sources of stress to which employees are permanently exposed in their workplace. Caring about employees, and safety and health protection at work is one of the important activities of the business function of human resource management. The priority task of experts in this field is to act preventively against stressors by creating various methods and techniques for their efficient and effective management. One of the techniques that is becoming increasingly popular in socially responsible organizations, are wellness programmes. By organizing and implementing these programmes, the management of the organization shows that it cares and acts preventively to maintain the safety and protection of the health of its employees, and the employees themselves acquire new knowledge and healthy life habits through these programmes. This paper points out the importance and role of wellness programmes, as important activities of strategic human resource management of modern organizations, which occupies a significant position in the protection and prevention of employee health. Also, the paper outlines all the important elements that management should keep in mind when designing and implementing wellness programmes in order for them to adequately influence the improvement of physical and mental health of employees.

The second most important source of indoor radon, after soil beneath dwelling, is building material. With the increase in environmental awareness and new energy-saving policies, residents tend to replace the existing windows with tighter windows, which leads to a decrease in air exchange rate and consequently an increase in indoor radon concentration. In case of low exchange rates, dose caused by inhalation of radon and its progeny can exceed external dose originating from the radium content in the surrounding building material. In this paper, surface exhalation rates of radon (222Rn) and thoron (220Rn) from typical building materials used for construction and interior decoration of houses in Serbia were investigated. Surface exhalation rate measurements were performed using the closed-chamber method, while concentrations of radon and thoron in the chamber were continuously measured using an active device, RTM1688-2, produced by SARAD® GmbH. Finally, the impact of the replacement of windows on the indoor radon concentration was estimated.

The contemporary media culture in Serbia has been marked by two trends - democratization and transformation of the media. These parallel processes on the eve of the 21st century led to the decrease in informative contents and the increase in the entertainment ones. Therefore, reality shows take primacy in Serbia, no longer being an exclusive feature of the television. This paper is aimed at researching and describing the ways in which informative contents in the Serbian media have been replaced by television reality contents, as well as the ways in which the printed media and internet portals inform about them. By the qualitative method of content analysis, this paper realizes its goal to fathom the mechanisms of the transposition of the informative content into the entertainment one, thus deconstructing journalistic practices. The results will indicate that the domestic portals relate to realities in two ways - the first and less common modality is ignoring, while the second implies uncritical acceptance of this type of content, which creates fertile soil for the development and maintenance of the so-called reality culture.

Various imported building materials commonly used in construction and industry in Serbia were analyzed using gamma spectrometry. Based on the activity concentrations of 226Ra, 232Th, and 40K in the investigated samples, radium equivalent activity, Raeq, absorbed dose rate, D, annual effective dose, DE, and the external hazard index, Hex, were calculated to assess the radiation hazard for people. The Raeq for most of the analyzed samples (416 in total) was lower than the maximum admissible value of 370 Bqkg-1 set in the UNSCEAR report. The absorbed gamma dose rate in air was found to vary from 0.030 mGyh-1 to 1.328 mGyh-1 which in some cases exceeded indoor dose rates in Europe. The obtained values for annual effective dose exceed the limits of 0.41 mSv given in literature for about 5 % of measured samples, while values of Hex were higher than unity for three samples of cement, eight samples of granite, and one sand sample. As a possible source of elevated effective dose, the radon exhalation from building materials was estimated using the parameters given in literature. The internal dose due to 222Rn exhaled from the building material was found to be up to nine times higher than external dose due to 226Ra content in some cases.

This paper examines the impact of digital technologies and tools on business communication in the contemporary business environment through the prism of new communication channels. Every technological breakthrough throughout history has altered the way people communicate, beginning with the discovery of the printing press, telegraph, radio, and television. In the fifth industrial revolution and contemporary environment, business communication becomes increasingly focused on current digital technologies and tools. Traditional communication, which was inherently slow, is being phased out in favor of interactive and quick communication. Communication through modern digital technologies and tools has many benefits, but it also has some drawbacks, including the possibility of misunderstandings and conflict. This paper discusses the digital age’s key communication channels, including smart mobile phones, short messages (sms), multimedia messages (mms), voice mail, Viber, WhatsApp, iMessage, Skype, Google Hangouts, Slack, teleconferences, video conferences, e-mail, intranet, organizational social and professional networks, and various business communication applications. Besides from their essential characteristics and advantages, this paper highlights key limitations that should be considered in order to eliminate or lessen misunderstandings and conflict situations.

Research Question: The key research question is what the key positive and negative perceptions of students from the Republic of Serbia regarding workplace robots are. Motivation: Academics, practitioners, and decision-makers are more and more interested in the impact of new technological solutions in the field of robotics on organizations and their functioning. Ongoing technological advancements have accelerated the adoption and use of robots in the workplace. As a result, organizations that plan to introduce robots should consider all effects on employees, both positive and negative. Idea: The main idea is to examine and analyse the perceptions and attitudes of students from the Republic of Serbia regarding robots at the workplace. The results of this study regarding students' perceptions and attitudes towards robots in the workplace are crucial for the future of work and job design. Data: Data were collected via online questionnaire consisting of five profile questions and 13 statements organized in two five-point Likert scales. From January to March 2023, the questionnaire was completed by 164 students from the Republic of Serbia. Tools: The collected answers were analysed using the Statistical Package for Social Sciences - SPSS, version 21.0. (Armonk, NY: IBM Corporation). The Cronbach's Alpha coefficient, Kolmogorov-Smirnov test, descriptive statistics, student t-test and one-way ANOVA test was used for data analysis. Findings: Research results showed that most respondents believe that robots can do dangerous jobs that humans cannot, that robots can free humans from routine and monotonous jobs, and that humans will have more time for creative tasks. Robots in the workplace, on the other hand, will have some negative consequences. Many respondents agree that working with robots without people would make them feel lonely; robots would not know how to react in some unexpected circumstances; and they are not as flexible and mobile as humans. Contribution: The findings of this study could make a significant contribution to a better understanding of students' attitudes towards robots in the workplace and they may help decision makers, employers, leaders, and managers on how to increase workplace acceptance of robots.

Visual merchandising is actually a technique, ie. mastery of different methods to promote the sale of goods by improving their presentation in the shop window and the object itself. It also includes certain components of ambient design using visual rhetoric and communication, primarily through visual imagery, sending symbolic messages, to arouse a perceptual and emotional response in a potential customer, and finally to influence its behavior in the store by bringing him into the brand identity. In the book Death of Fashion, Harald Gründl studies fashion showcases that appear twice a year, when a new fashion collection arrives in stores, in an atmosphere of beautifully decorated showcases and is out of fashion at the end of the season. The seasonal period of sale, before a new product collection each Spring-Summer and Fall-Winter became the transition phase between the old and the new collection, when the beauty of visual merchandising disfigured.

The crystal structure of new lanthanum strontium borate glass-ceramics was refined by the Rietveld method. The results showed that La2SrB10O19 has the monoclinic crystal structure, space group C2 (No. 5) with a = 11.1170(6), b = 6.5667(3), c = 9.2363(3) Å, β = 91.481°, V = 674.04(7) Å3, two formula units per unit-cell, and density 3.830 g cm−3. The main building units of the crystal structure are BO4 tetrahedra and BO3 triangles. Clusters composed of [B5O12] form an infinite double layer running perpendicular to the c-axis. Lanthanum atoms, situated in [B5O12]n layers, are coordinated with 10 oxygen atom in a form of LaO10 polyhedra, while Sr atoms, located between [B5O12]n layers, are coordinated with 8 oxygen atoms in a form of SrO8 polyhedra. Microstructural measurements contain both crystallite domain sizes and microstrain calculations obtained by the Warren-Averbach and the simplified integral-breadth methods.

As a result of the separation of ownership from control and relationship between the owners as principals and managers as agents, the so-called agency problem arises. In order to alleviate the agency problem in transition economies, internal corporate governance mechanisms are applied. Culture is considered as one of the most important factors within an informal institutional framework that is often associated with the effectiveness of corporate governance mechanisms. Starting from the fact that the board is an important internal mechanism, this paper examines the national culture as a determinant of the board structure based on a widely accepted cultural framework developed by Geert Hofstede. The aim of the research is to obtain relevant scientific knowledge on whether the board structure, analyzed through board composition and size, differs in countries that have similar dimensions of national culture. The research is carried out on a sample of 60 companies in Serbia and Montenegro. Relying on the T-test, the research showed that the boards composition in these countries differs, while their average size is the same. This pilot study mitigates the research gap that exists in domestic literature and represents the basis for future research in this area.

Stroke is a clinical syndrome, and one of the leading causes of death and disability, occurring under the influence of a large number of risk factors. The symptoms of a stroke are in correlation with the size, time and location of the lesion. Rehabilitation, which involves the application of conventional and supplementary methods, relates to the assessment of the ability, the level of damage of the affected functions, and an adequately designed rehabilitation program. The use of dance, as a rehabilitation procedure in post-stroke patients, requires listening and active participation of an individual with a specific motor reaction to the stimulus. The primary aim of this article is to demonstrate the importance and effects of the application of dance in the rehabilitation process in post-stroke patients, with a special emphasis on the process of improving motor skills and functions. In accordance with the set criteria and purpose of study, scientific research papers were collected and analysed from the PubMed/MEDLINE, Science Direct and Oxford Academic databases, all published in the period between 2010 and 2019, and all indicating the importance of the application of dance when treating post-stroke conditions. The obtained results suggest that dance, which is basically a sports-recreational activity, when applied for therapeutic purposes in persons after stroke, contributes to the development and recovery of motor abilities, balance, mobility, endurance, coordination, motor skills, stance, walking and precision. Also, dancing is of great importance for the improvement of the functioning of the whole organism, which directly or indirectly affects the recovery of motor functions and the overall welfare of an individual.

Respecting the importance of corporate governance (CG), particularly various corporate governance mechanisms for improving corporate social responsibility (CSR) activities, the paper highlights relevant CG–CSR synergies from the perspective of systems thinking. The paper further aims to demonstrate the ways in which selected systems methodologies can support CG–CSR synergies. Accordingly, we selected appropriate systems methodologies, such as dialectical systems theory, soft systems methodology, and system dynamics. We defined the dialectical system, consisting of essential corporate governance mechanisms, which contribute to CSR; we also identified the key stakeholders and their perceptions of CG–CSR relations through CATWOE analysis; thus, the appropriate root definition and conceptual model, including the activities that are relevant for CG–CSR relations, were developed. Developed systemic framework provided a relevant methodological support to highlight the various issues of corporate governance, such as institutional framework, market for corporate control, ownership structure, board structure, and their contribution to CSR.

This paper explores the distribution pattern of SAR1g within the adult male head during utilization of hands-free operation of contemporary mobile phones as a source of electromagnetic radiation. The research assesses the optimal positioning of the mobile phone by examining three distinct orientations to determine the minimal SAR1g distribution compared to the conventional talking position when hands-free feature is not utilized. The analysis encompasses GSM bands operating at 900 MHz and 1800 MHz, depending on the alignment between the mobile phone and the head. [ABSTRACT FROM AUTHOR]

Crystallization kinetics of 22.5Li2O•10Al2O3•30GeO2•37.5P2O5 (mol%) glass was studied under non-isothermal condition using the differential thermal analysis (DTA). The study was performed by using the first crystallization peak temperature (Tp1) which belongs to the precipitation of LiGe2(PO4)3 phase in the glass. The activation energy of glass crystallization (Ea) was determined using different isokinetic methods. The dependence of Ea on the degree of glass-crystal transformation (α) was studied using model-free isoconversional linear integral KAS (Kissinger-Akahira-Sunose) and FWO (Flynn-Wall-Ozawa) methods. It was shown that the Ea varies with α and hence with temperature and consequently the glass/crystal transformation can be described as a complex process involving different mechanisms of nucleation and growth.
