Aim: The objective of this study was to determine the oxidative status of saliva and plasma in diabetic children, by analyzing advanced oxidation protein products (AOPPs) and total antioxidant capacity (TAC). Materials and methods: Study included 60 patients with diabetes mellitus type I (DMT1) aged 12.45 ± 2.65 years, and 40 healthy age-matched controls. The AOPP and TAC of the plasma and saliva samples were determined using a commercial QuantiChromTM Antioxidant Assay Kit (DTAC-100) for TAC determination, and Immunodiagnostic AG [enzyme-linked immunosorbent assay kit for AOPP]. Results: Values of salivary and plasma AOPP were lower in diabetic patients than in healthy controls, while value of TAC was clinically and significantly higher in plasma of controls, and clinically higher in saliva of healthy control group, compared with diabetic patients. Average value of hemoglobin A1c (HbA1c) was 7.58 ± 0.85%. Conclusion: Results of this study showed that diabetes mellitus as a condition, with well-controlled HbA1c, has no influence on AOPP levels in saliva and plasma, while TAC levels of saliva and plasma are lower in diabetic patients, which means that DMT1 has an influence on the TAC.

This paper presents method for sustainability assessment of thermal power plant unit using multi-criteria analysis with aim to create base for business decision. Seven options of possible status of thermal power plant „Kolubara A” unit No. 2 with energy indicators of sustainable development were shown. Energy indicators of sustainable development consists of sets of resource preservation, economic, environmental, and social indicators. Sustainability assessment often fails to account for social influence on energy system. Considering to this, special focus will be on social indicators, their definition, forming, and impact on multi-criteria sustainability analysis. Analysis of quality of the selected options (energy systems) in respect to sustainable development by compare of their general index of sustainability is presented. Methodology of multi-criteria analyse of thermal power plant unit can show decision makers how to find best available options when the social indicators impact is leading. The aim of this paper is to choose the criteria for the evaluation of the available options, determine the relative importance of specific criteria and present methodology of multi-criteria analysis in the decision-making process.

Credit risk is the most important risk among all other risks in the banking business, because almost over 80% of bank balance sheets relate to this segment of banking risk management. One of the biggest problems of commercial banks in Bosnia and Herzegovina are non-performing loans whose share in total loans has increased significantly since the onset of the global financial crisis. The main objective of the research is to determine which of the macroeconomic variables have the strongest impact on the increase of return on average equity and whether it is possible to reduce the credit risk of banks with adequate legislation as the main factor in the slowdown in credit expansion. The main goal will be to divide the impact of an independent variable, i.e. the share of liquid assets in total assets and whether its increase indirectly affects the return on equity and indirectly, the credit risk. The quantitative model used in this study will be the Merton model. Testing will be conducted through multiple regression analysis for the period 2008-2016 with the help of the software package STATA.

Tržišta akcija su efikasna ako cene u bilo kojem momentu reflektuju sve javno dostupne informacije. Cene akcija bi trebalo da se prilagode u momentima kada investitori pokušavaju da iskoriste nove informacije koje nisu bile predmetom računovodstvenog evidentiranja. Osnovni cilj ovog rada je da se utvrdi da li zaista finansijski izveštaji odabrane skupine preduzeća koja kotiraju na Sarajevskoj i Banjalučkoj berzi predstavljaju dobru baznu osnovu i odraz tržišnih cena ili naprosto služe kao zakonska obaveza i zahtev regulatornih agencija. U radu će biti sprovedena regresiona analiza zavisne i nezavisnih varijabli za period od 2011. do 2015. godine. Kao zavisna varijabla će biti tretirana zatvarajuća cena trgovanja na berzama, dok će se kao nezavisne varijable koristiti sledeće: odnos tržišne cene i zarade (PE racio), zarada po akciji (EPS), neto dobit nakon oporezivanja (ND), ostvareni profit na akcijski kapital (ROE), odnos tržišne i knjigovodstvene vrednosti (PB), i ukupan promet na berzama (PR).
