The challenges of the COVID-19 pandemic are important and relevant for sustainable development. The aim of this chapter is to review the existing model of economic development, because the COVID-19 pandemic has called into question the effects of structural changes in the economy and manufacturing industry in Serbia. The main contribution of this chapter is the review of development results which show that Serbia is in the process of economic recovery, but that it has not yet embarked on the path of sustainable economic development due to numerous structural problems. Serbia has experience with unsustainable economic development, and this is a strong argument in favor of sustainable concept implementation. In addition, this chapter provides empirical research on structural and technological changes. The obtained results can be used by economic and industrial policy makers to influence the consequences of COVID-19 and to avoid the slowdown of structural reforms. There will be numerous economic, environmental, social, and especially health challenges whose solutions must be sustainable.

For applications as an engineering material, the ability to design properties is of special importance, ie. structuring materials that can be achieved on several levels and in different ways. One of the goals of this research is the development of procedures that would enable the production of silicone polymer nets with improved mechanical, elastic and thermal properties. These materials mainly relate to the dimethylsiloxane structure, which is known for its biocompatibility, in polymeric states. FTIR spectroscopy was used to confirm the presumed mechanism of the siloxane crosslinking reaction. The aim was to further elucidate the mechanism of interaction of silicone materials based on the obtained results of the analysis of mechanical properties of silicone nanocomposites.

Traffic safety problems are complex problems, which is why the competencies and skills acquired by engineers should provide knowledge and a deeper understanding of risk while strengthening the applied and practical skills. Innovative study programs must have a common basis for all directions, with a deep knowledge of mathematics, physics and mechanics with an emphasis on a holistic and interdisciplinary approach to the use of engineering in improving traffic safety.

The paper lists the major projects of international financial organizations in Bosnia and Herzegovina (BiH) after signing the Dayton Peace Agreement to explore the role of international financial organizations in post-Dayton BiH. It discusses the specific contribution and the role of these organizations in functioning of BiH, including financial assistance, credit means, various funds and projects, which have been supposed to lead to the stable functioning of BiH after the signing of the Dayton Peace Agreement. The paper explains the role and attentiveness of the Monetary Board in BiH with a focus on its impact on implementation of the international projects. The research question is: “From which sources did the largest funds in BiH come in the period from 1996 to 2020 and how were they related to GDP?”. The paper is based on publicly available data from international financial institutions and the Ministry of Civil Affairs of BiH. The results show that about 71.45 billion dollars entered BiH from international financial institutions through donations, grants, loans, and other various types of assistance. But the funded projects did not have the same priorities every year and in every area. In addition, international funds were used to finance numerous projects aimed at economic recovery and economic development. In the last few years, there

With the advent of novel 2D materials and their rich optical and electronic properties, nonlinear interactions in these systems are receiving great attention due to the scalability potential and production of nanoscale nonlinear devices for applications in frequency conversion devices, advanced laser systems and quantum technologies research and applications.

The research affirms the meaning and importance of solfeggio as one of the basic areas in the process of music education, and how much does the understanding of its conception affect the overall attitude about its potential and perspectives in the field of music pedagogy. For research purpose, a questionnaire was created aimed at the subjective assessment of respondents about the success of the continuous implementation of online solfeggio classes. Results indicate that online solfeggio classes have their advantages but also various serious issues. The most notable emerging problems are related to the conducting of basic forms of work which require an environment where students can engage with their peers and teacher in a face-to-face setting. Solfeggio classes are based on intensive interaction and many methodical procedures can be successfully performed only in group work and direct communication because the basic disposition of solfeggio teaching is in the classroom.

: Antigenotoxic and Antioxidative activites of Curcumin Modern biomedical science has proven beneficial effects of curcumin as potential therapeutic candidate for various conditions due to its pleiotropic and pharmacological properties. The aim of the present study was to investigate antigenotoxic effects of curcumin against cisplatin induced genotoxicity as well as its antioxidative effects. In vitro cytokinesis block micronuclei assay in human lymphocytes was used for evaluation of antigenotoxic properties of curcumin. Evaluation of antioxidative properties of curcumin was determined with 2,2-Diphenyl-1-picrylhydrazyl free radical scavenging assay. Results demonstrated significant antigenotoxic and antioxidative properties of curcumin, dependent upon the tested concentrations. Consideration should be given to performing a study with broad dose interval of tested substances. Findings from the present study emphasized application of curcumin as potential antigenotoxic and antioxidative supplementary agent.

The financial reports, as the final product of the accounting information system, need to be accurate in order to maintain the main purpose of financial reporting. Applied methods and techniques of recognition and measurement of financial positions should be in the purpose of realistic and transparent presentation of the financial performances of the entity. However, creative accounting techniques are often used in the process of preparing and presenting financial statements in order to manage earnings and manipulate financial values. Manipulation of financial statements seems to be a generally present phenomenon, and the paper aims to identify the criteria used by members of the accounting profession in the Federation of Bosnia and Hercegovina (FBiH) to distinguish earnings management techniques from fraudulent financial reporting. The research reflects the perception of accountants and auditors in the FBiH regarding the possibility of recognizing suspicious accounting practices in business entities. The research is based on distinctive criteria used in developed economies of the world: measurement subjectivity, the materiality of financial item and compliance of financial reporting with generally accepted accounting principles, but identifies specific distinctive measures used by respondents, too. The results of the research reveal that the accounting professionals in the FBiH rely on distinctive criteria: materiality and compliance of reporting with International Financial Reporting Standards, including two additional measures: compliance of financial reporting with generally accepted practices and confidence of financial information. Respondents did not recognize subjectivity in assessment as a relevant measure of the distinction between earnings management and fraudulent financial reporting.

Background: Retained placenta is one of the major causes of primary and secondary post-partum hemorrhage (PPH) and active management of the third stage of labor reduces the risk of PPH. Objective: The aim of this paper was to compare the efficacy of intra-umbilical vein injection of carboprost versus oxytocin by time and success rates of total expulsion of the placenta. Methods: This prospective clinical study with quasi-experimental design 2x2x2(risk factors by medication by doses) was conducted at Clinic of Obstetrics and Gynecology, Clinical Center of University of Sarajevo in two-year period. Patients were randomized in 4 groups and 8 subgroupsby different medication doses and risk factors. The main outcome variable was expulsion of retained placenta and second outcome variables were: duration of time from intra-umbilical vein administration of drug to expulsion of retained placenta, the number of cases who required blood transfusion and antibiotics, postpartum hemoglobin after 24h. Statistical significance was accepted for p-values < 0.05. Results: The group B2 (UVI oxytocin 20 IU in 20 mL saline, surgical risk factors) and the group D2 (UVI oxytocin 20 IU in 20 mL saline, non-surgical risk factors) had shorter expulsion time (minutes) (Me=5; IQR=4 to 5; Me=5; IQR=4.3 to 6, respectively) compared with other groups (p<0.001). The success rates of total expulsion of the placenta by groups (A,B,C and D) were not statistically significant (70% vs. 82% vs. 72% vs. 78%, respectively; p=0.483). Post-intervention hemoglobin concentrations was statistically significantly greater in the group B(117.3±1.3) vs. the group A (112.1±1.3), (p =0.028). Conclusion: The time for placental expulsion was significantly shorter and postpartum hemoglobin was significantly higher in the intra-umbilical oxytocin groups than in the carboprost groups.

Organizational configuration affects a number of management components, both hard and soft. Hard components include: organizational structure, strategy and control, and soft components are: organizational culture, organizational learning, leadership, motivation, organization power, organizational change, rewarding employees, evaluating performance and connection between individual and organization. Therefore, it can be said that organizational configuration affects organizational culture. The organizational configuration creates a framework in which a specific type of organizational culture is applied. For an organization to be successful in achieving its goals, there needs to be a high degree of agreement between the chosen model of organizational configuration and the type of organizational culture. Therefore, each model of organizational configuration corresponds with a precisely defined type of organizational culture, because only in that way organization will avoid problems in its functioning. This paper is an exploratory type, which means that it will create assumptions about the degree of agreement between specific models of organizational configurations and certain types of organizational cultures. In this paper, based on theoretical implications, assumptions are created about the degree of agreement of Mintzberg's models of organizational configurations, which are re cognized in the literature as Mintzberg's basic types of configurations and typologies of organizational cultures according to Cameron and Quinn, better known as the competing value model. Situational elements that form models of organizational configurations according to Mintzberg and the dimensions on the basis of which are performed the typology of organizational cultures according to Cameron and Quinn are taken into account.

The paper investigates the influence of organizational culture on the leadership style in the company. Every company needs managers who will develop a certain leadership style in order to meet the preconditions for effective actions that will lead to the achievement of the company's goals. Organizational culture in accordance with established norms and rules determines how to understand and accept specific employee behavior, and which leadership style is fitting for managing employees by managers of company leaders. The paper uses a situational approach to leadership according to which the typology of leadership styles is based on two key criteria: concern for people and concern for performance. The classification of organizational culture according to the Edwards and Kleiner typology is based on four types of organizational culture: indifferent culture, caring culture, strict culture and integrative culture. Based on the agreement of the criteria for differentiating the types of organizational cultures and leadership styles, hypotheses about cause-and-effect relations between them are set in the paper.
