The mixing of process colorants is conducted on cardboard with an inkjet plotter. In the article recipes are published for colorant compositions which are presented in pairs of equal colors in the visual spectrum. Every color in the family of colors with dual properties has the same difference ΔZ in the near infrared spectrum. The difference in the absorption of light at 900 nanometers is 0.14. In visual spectrum, the twins of two colorants are defined as colors with the value of their difference ΔE less than 3. Solutions using twins of colorants in two spectra have been experimentally tested in the print on drug packaging. Quality control of the readability of the text is conducted with new infrared mini-cameras connected to a tablet.

In the article is presented the design for security graphics on packaging with invisible information. The color choice is underlined by the INFRAREDESIGN® theory. Individual solutions for joining two independent images are realized with digital printing and interpreted with computer animation. Separation of the dye is performed for the default response of the hidden drawing that is released by the infrared camera. Product recognition is with IRD process as a "visual information identity". Hidden graphics are designed with a protective line solution. Experiments have been carried out in the pharmaceutical field, on the packaging of drugs. Proving the authenticity of the content is carried out by recording the packaging and comparing it with the specimen that was recorded as photographs of the twenty light blockades in the visual and infrared spectrum.

Mijesanje procesnih bojila provodi se za digitalni tisak na kartonu s inkjet ploterom. U radu se objavljuju recepture sastava bojila koje se prezentiraju u parovima jednakih boja u vizualnom spektru. Familija svih boja s dualnim svostvima imaju jednake razlike ΔZ u bliskom infracrvenom spektru. Razlika apsorpcije svjetla na 900 nanometra je 0.14 U vizualnom spektru, blizanci dvaju bojila definiraju se kao boje s vrijednoscu njihove razlike ΔE majom od tri. Rjesenja s upotrebom blizanaca bojila u dvama spektralnima podrucjima su eksperimentalno testirana u tisaku na kutijama za ljekove. Kontrola kvalitete citljivost skrivenih informacija izvodi se s novim minijaturnim infrared kamerama koje su prikljucene na prenosno tablet racunalo.

- Modern technologies provide advanced knowledge and prepare students for lifelong learning. They affect both education and upbringing. Electronic learning is now inevitable. The main goal is to create a modern school through information technology, and to abandon the current traditional way of working. Electronic learning offers many learning advantages where we will point out some of its most important features in the paper, and we will give guidance on how to apply it through several tasks related to the attitudes and opinions of teachers and students about its use, better results, more motivation for learning and similar. We have come up with a result where students and teachers advocate learning through information technology in classroom teaching and want to apply them in their work.

In this paper the application of problem teaching mathematics and respect its characteristics was investigated in the lower grades of primary school, in order to demystify its role and importance in enhancing the educational and functional effect. The research was done in the period from September to December 2015, by testing students of fourth grade in five elementary schools. Statistical analysis of the selected groups has shown there is no statistically significant difference between groups, and the test normality of distribution was done using the Kolmogorov-Smirnov and Shapiro-Wilk test. Analysis and comparison of results before and after the experimental program, indicates a significant improvement in students' knowledge and mathematical competencies applying the methodology that has been implemented.

This paper presents architecture of the software system for semantic e-mail addressing. It explores the possibilities for creating and updating the knowledge base system about employers and job vacancies, which is created based on domain ontologies. It also describes in details the process of publishing database on the Semantic Web and plans for further updating and improving the existing knowledge base system. Due to specific kind of work, and necessity of automating communication with employers, the presented system is applied in the Employment Agency of Montenegro.

AIM Standardization of education process and almost every aspect of life in EU moved the authors of this paper to evaluate medical informatics education at medical schools in Bosnia and Herzegovina. A very complex political structure and existence of two entities, one district and ten cantons in the Federation of Bosnia and Herzegovina caused great differences in the curricula, teaching methods and quality of acquired knowledge among medical schools in the country. Also, on the example of the teaching process at the Medical School, University of Sarajevo, the authors propose a future united and integrated system in the area. METHOD Method of the study is descriptive, comparing education in medical informatics at five B&H medical schools. Over 500 students answered questionnaires designed at medical schools in Sarajevo and Tuzla. The questions tackled the contents of the subject of medical informatics, the possibility of acquiring knowledge from both practical and theoretic lessons, "good" and "bad" sides of the curricula as well as students' computer literacy. RESULTS The subject of medical informatics is being taught in at least 3-4 different ways. Medical schools in Banja Luka and Foca/Srbinje are under a strong influence of the University of Belgrade, Serbia and Montenegro; the teaching staff in Mostar are from Croatia; the University of Tuzla has its own way; and Medical School in Sarajevo maintains high quality values and principles. Things and events that distinguish the Medical School, University of Sarajevo is the fact that it is the only medical school in Bosnia and Herzegovina which has a web site of of the Department of Medical Informatics, organized a number of events including a distance learning course, and has a highly competent teaching staff. Medical School in Sarajevo is the oldest medical school in Bosnia and Herzegovina established in 1944. As a required subject, medical informatics was introduced in the academic year 1992/1993, and it is the only medical school in Bosnia and Herzegovina where medical informatics is taught in two semesters, second and eleventh. DISCUSSION Three important areas are discussed: the quality of education in secondary schools should be improved; the lack of multimedia equipment, good LAN, high-speed connection to Internet and well organized web design, and issues related to maintenance of equipment; and students should have free access to computer rooms to enable them to extend their knowledge in spare time; general information about health system should be available to students to allow them to require the role and importance of medical informatics in "real life". Naturally, we raise the question of unique and systematic medical informatics education in the whole country, irrespective of entities, nationality or religion of students. CONCLUSION Medical informatics education at Medical School, University of Sarajevo, is based on the same concept as on prestigious universities all over the world and in accordance with recommendations of the working groups on education of EFMI and IMIA. Other medical schools in Bosnia and Herzegovina should employ the same methodology and system of work in order to have standardized education in medical informatics and to achieve high quality in education. To enable us to follow the European and global achievements in this area, the power of fact should predominate in the education system as well as in the health system.
