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.

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.

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.

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.

Europe, with all its common sights, has an enviable wealth of history and cultural heritage. With its many monuments, sites, traditions, history, art, and culture, it has always attracted curious views and tells centuries-old stories to many tourists and visitors. At the heart of Europe, Bosnia and Herzegovina (BiH), founded in the 11th century, with its picturesque past, has always been at the crossroads of faith and civilizations. The key audience of tourism in BiH are nature lovers, adventurers and young and digital nomads, who represent great potential for the development of this sector given their nature of work, to be able to work from any location, and during the COVID-19 period. Furthermore, the importance of the diaspora for the development of tourism in BiH goes beyond tourist visits and helps BiH on its path to digital transformation. Digital tourism refers to how we use digital tools to organize, manage and even enjoy the travel experience. It uses all of the tools of digital transformation to change how we travel and experience different sites. Through digitalization, we want to reach every individual who passes through this country and further attract lovers of European history and culture, offer them a different, more creative, and innovative approach to learning about the cultural and historical treasures it hides. The goal of digital tourism is to raise awareness of the importance of cultural heritage, provide new opportunities for visitors and bring new knowledge. Therefore, this paper provides an overview of the possibilities of digital representations of the medieval historical period of BiH through identified pillars of digital reconstruction, and ways to connect the movable cultural heritage residing in the museums with real sites in an attempt to contribute to its promotion through digital tourism. © 2022 Copyright for this paper by its authors.

The paper points out the leading role of the HR department in crisis situations, with special emphasis on the crisis caused by the COVID-19 pandemic, which affected the whole world in early 2020. Regardless of the intensity and form in which they occur, crises threaten the functioning and survival of organizations. The HR department is an important factor in the successful functioning of organizations and, in a period of crisis, this department takes a leading role in the process of crisis management and subsequent recovery. During COVID-19 pandemic, the HR department of every organization had to confront new challenges in order to protect the health of employees, while ensuring the normal functioning of organizations. In order to find out how this department dealt with crisis that occurred, empirical research with a specially designed questionnaire was conducted and filled in by 108 respondents from Serbia, Bosnia and Herzegovina, and Croatia in 2020. The research results showed that HR department has taken a leading role in preserving the health and safety of employees, as well as in the process of adapting organizations to function in crisis conditions. According to results, the key activities carried out by the HR department in organizations are work from home (wherever the nature of the work allowed), flexible working hours, reorganization of the working space to achieve the required physical distance between employees, improved hygiene measures, etc. In addition, the research results showed that, during the global COVID-19 pandemic, the HR departments took an active role in providing psychological assistance to employees to adapt to new conditions and ways of working.

Selective separation and removal of a metal species from complex matrices of other species is of critical importance in separation sciences and especially in industrial processes. The selectivity and efficiency of Pb(II) ion removal from an aqueous solution in the presence of Ni(II), Zn(II), Co(II), Cu(II), and Cd(II) ions as competing ions in a multi-component aqueous source phase through bulk liquid membrane system were investigated. The influence of the palmitic and oleic acid as supporting surfactants in the membrane phase on the removal of Pb(II) ions was also analyzed. Dicyclohexano-18-crown-6 dissolved in chloroform, proved to be a selective and efficient carrier for Pb(II) ions. In the optimized procedure, 3 hours of equilibrium time was required to achieve the maximum removal efficiency. It was found, that removal of Pb(II) ions was achieved without significant reduction in the efficiency compared to the liquid membrane transport of a single-component system. None of these cations interfered with Pb(II) removal. The presence of the oleic and palmitic acid in the membrane phase increase the content of Pb(II) removed to the receiving phase. In optimal transport conditions, more than 97% efficiencies for the removal of Pb(II) were obtained for a system supported by oleic acid. The excellent efficiency and high degree of selectivity for the Pb(II) ion removal by the proposed BLM system, reveals its potential application for the selective removal, concentration, and purification of lead ions from its different mixtures.
