Mila Kavalić, Milan Nikolić, Dragica Radosav, Sanja Stanisavljev, Mladen Pečujlija
2021 Sustainability  
This paper analyses the level of knowledge management implementation in organizations and the impact of control variables on knowledge management dimensions. In addition, the importance of knowledge management influence on the competitive sustainability of an organization is addressed. The idea of the research is to highlight key factors that affect the effectiveness and efficiency of knowledge management applications in transition conditions. Data for the study were obtained by surveying 520

More precisely, the t-test analysis was conducted on the average assessments of knowledge management dimensions and with specific control variables. The findings indicate that knowledge management dimensions differ in domestic enterprises and foreign enterprises as well as that their impact differs across organizational levels. Financial performance (profitability, sales growth, asset growth, market share, competitive position in a specific industry, productivity, and salaries) was found to be a reliable indicator of knowledge management success. It can be concluded that knowledge management dimensions have an important role in transition countries, and it is evident that effective knowledge management is imperative for the competitive sustainability of an organization.

Bojan Ivetic, Dragica Radosav
2014 TEM Journal  
The aim of the research is to predict specific output characteristics of half finished goods (crude sunflower oil and meal) on the basis of specific input variables (quality and composition of sunflower seeds), with the help of artificial neural networks. This is an attempt to predict the amount much more precisely than is the case with technological calculations commonly used in the oil industry. All input variables are representing the data received by the laboratory, and the output variables

The paper presents a procedure for determining the optimal amount of thermal energy for the profitable operation of a biogas plant. The temperature at which anaerobic fermentation takes place shortens the time of fermentation and biogas production, but also the provision of higher temperatures requires a certain amount of thermal energy, whose consumption reduces the energy effects of the biogas production system. In this paper the results of the average outdoor temperature and the temperature

The required thermal energy for heating the fermenter is presented in percentages, on average 16 % in relation to the total produced thermal energy. Careful analysis determined that the temperature for most profitable anaerobic fermentation process (mesophilic temperature is 40.5 °C), so that the fermentation rate would be optimal with the use of minimum amount of thermal energy to heat the fermenter.

The main aim of this study was to fi nd out whether there are differences in the achieved results in two ways of testing: computerbased testing and paper-and-pencil test. Also, the intention was to detect those characteristics of computer based test, which may have a negative effect on students' achievements. The participants were a representative sample of the population of all engineering students studying computer science at Subotica Tech. The fi ndings of this study led the authors to reach the conclusion that there are no signifi cant differences in scored results for the paper-and-pencil testing and the computer-based testing.
