After having analyzed recent catastrophic events that happened in the Republic of Serbia caused by flash flooding, at first glance the struggle with floods seemed to be lost. Yet, famous Serbian persistence or just a mere struggle for life of the citizens who showed extraordinary social solidarity in such difficult moments were crucial once again. The unity was expressed in many ways, by providing assistance to the most vulnerable people in the evacuation of flooded areas, delivering basic foodstuffs and medical assistance, as well as in the field of telecommunications whose scope of work was very important but publicly invisible in 1 milan.gligorijevic@mup.gov.rs 2 mboskovic@fb.bg.ac.rs 3 aleksandar.maksimovic@mup.gov.rs Milan Gligorijević, Milica Bošković, Aleksandar Maksimović [112] NBP • Žurnal za kriminalistiku i pravo such critical moments. Without such “key hub” that connected all relevant state factors into a whole providing them constancy and continuity in communications, everything was pointless. This event, no matter how difficult and tedious, opened the subsequent analysis of many issues and spawned some great ideas. One of them is legally obliged introducing of “National roaming” at all telecommunication operators in our country, which is also discussed in this paper.

The aim of the paper is to point out the impact of the insurance contract on the safety of agricultural producers in the Republic of Srpska, based on the assumption that the insurance of crops, fruits and animals is a factor that implies elimination of harmful consequences in case of damage. This attitude of the authors is based on the fact that with the conclusion of an insurance contract in agriculture, the part of the responsibility is transferred to the state (by participation in the co-financing of the insurance premium), then to the insurance company (by claiming the damage from the insurance) and finally to the agricultural producers. Bearing in mind that insurance is very present in all segments of the modern society, which implies a great variety of forms of insurance, the authors of this paper start by presenting a general structure and classification of insurance, which also includes the insurance for agricultural purposes. In order to get a realistic picture of the current state of insurance in agriculture in the Republic of Srpska, an analysis of the legal regulation that regulates the mentioned issues was carried out. The authors also conducted a survey among agricultural producers to analyze the reasons why they have a negative interest for this segment of insurance and thus a small number of closed insurance policies with insurance companies. Based on these findings, this paper gives recommendations for the improvement of the situation and proposals for better solutions which would raise the safety of agricultural producers to a higher level.

In this research we propose a comprehensive set of knowledge indicators aimed to enhance learners’ selfreflection and awareness in the learning and testing process. Since examined intelligent tutoring systems do not include additional messaging features, the introduction of common set of knowledge indicators differentiates our approach from the previous studies. In order to investigate the relation between proposed knowledge indicators and learner performance, the correlation and regression analysis were performed for 3 different courses and each examined intelligent tutoring system. The results of correlation and regression analysis, as well as learners’ feedback, guided us in discussion about the introduction of knowledge indicators in dashboard-like visualizations of integrated intelligent tutoring system.
