Optical character recognition represents the mechanical or electronic conversion of handwritten, typed or printed images into coded text. Optical character recognition is widely used as a form of data entry from records that have been printed, and it can include invoices, bank statements, passports and many more. In the research, Optical character recognition reads data from the Re-Captcha dataset of images, converts them into strings, and these strings are used for testing, training and calculating prediction accuracy. The methodologies used are Convolutional neural network and Recurrent neural network. The convolutional neural network consist of neurons that receive data and group them according to similarity. A recurrent neural network cycle can be created between the connections of nodes, allowing the output from nodes to influence the subsequent input to other nodes. For data were used Re-Captcha images, and for the prediction of characters from images was used TensorFlow with Keras. The best results that are produced can be compared between first and last result, where the loss for first result was 20.63 and value loss was 16.45, while last result has loss of 0.56 and value loss of 2.96

There is a growing technological development in intelligent teaching systems. This field has become interesting to many researchers. In this paper, we present an intelligent tutoring system for teaching mathematics that helps students un-derstand the basics of linear programming using Linear Program Solver and Service for Solving Linear Programming Problems, through which students will be able to solve economic problems. It comes down to determining the minimum or maximum value of a linear function, which is called the objective function, according to pre-set limiting conditions expressed by linear equations and inequalities. The goal function and the limiting conditions represent a mathematical model of the observed problem. Working as a professor of mathematics in high school, I felt the need for one such work and dealing with the study of linear programming as an integral part of mathematics. There are a number of papers in this regard, but exclusively related to traditional ways of working, as stated in the introductory part of the paper. The center of work as well as the final part deals with the study of linear programming using programs that deal with this topic.

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.

: 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.

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.
