The main purpose of the study was to evaluate the information and communication technology (ICT) sector in the teaching process based on teachers’ attitudes and the strategic collaboration between universities and industry. The most common issue faced by the graduated students is to find a desired job at the end of the course of study. The main obstacle in finding a desired job is not enough ICT knowledge, which is not adequately learned at universities. On the other hand, the ICT teaching process at universities could be slow because many teachers do not have the right attitude toward ICT application in the learning process. In this study, a survey was performed among ICT working students and ICT teachers as well to reveal the relationship between the skills required for a job and the skills being taught at universities; whether the employability skills of fresh graduates increase hiring opportunities. The sample of examinees for this study consisted of the ICT sector in the European Union as well as ICT teachers based on the World Bank database. The proposed model was analyzed using structural equation modeling. It was found that the relationship between the academic program and job market along with ICT skills affected the employability factor. Hence the relationship between the academic program and job market significantly affects the employability factor. In effect, more focus on designing the academic curriculum is needed.

In order to provide a novel analytically traceable free space optics (FSO) channel model for describing turbulence based irradiance fluctuations, following basic scintillation theory principles, we have derived closed-form expression for probability density function (PDF) of a new statistical Gamma–Chi-square model. Further, capitalizing on provided model, error performances of FSO system over on–off keying (OOK) transmission scheme both in the presence of atmospheric turbulence and misalignment fading (pointing error) is investigated. For both cases, the average bit error rate (ABER) at the receiving side of the system is determined in an analytically closed form. The results are graphically presented in order to analyze the impact of different levels of turbulence, as well as other relevant parameters, on the quality of the received signal in the OOK modulated FSO system.

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.
