Тржиште малопродаје у Републици Српској једно је од најбрже растућих тржишта у последњих двадесетак година. То није случај само у Републици Српској и окружењу, већ и широм свијета. Доказ за то представља раст ланаца маркета, мегамаркета, тржних центара и других специјализованих малопродајних објеката. Много је лакше остварити раст на тржишту, а тиме и пословни успјех, него задржати конкурентност на изузетно пробирљивом и релативно доброснабдјевеном тржишту, какво је малопродајно тржиште Републике Српске. Један од начина задржавања конкурентности и истовременог раста је унапређење продаје којим продавци разним инструментима стимулишу потрошаче како би куповали производе из широког асортимана властите понуде.Циљ овог истраживања је управо да се утврди како и на који начин унапређење продаје утиче на понашање потрошача у куповини. Цјелокупно истраживање заснива се на потврђивању постављених хипотеза, а добијени резултати се могу користити у даљем истраживању и доказивању како инструменти унапређења продаје утичу на понашање потрошача.

Pojava međunarodnih otmica djece nije novijeg vijeka, iako je termin „otmica“ relativno novijeg datuma. Proučavanjem antičkih pravnih izvora (rimsko pravo, prava u antičkoj Grčkoj, prava u Mesopotamiji, itd.) mogu se pronaći pravni fragmenti koji govore o roditeljima koji svoje dijete „odvedu“, roditeljima koji svoje dijete „zadrže“, roditeljima kojima dijete „pripadne“ i sl. Međunarodne otmice djece, odnosno protivpravno odvođenje djeteta iz jedne države u drugu, predstavlja problem kojiza sobom povlači niz otvorenih pitanja blisko povezanih sa ličnošću djetata, dok pravno gledano, takva pojava dovodi do sukoba zakona i nadležnosti između različith država, odnosno države djetetovog uobičajnog boravišta i države u koju je dijete nezakonito odvedeno. Države kroz prizmu instituta međunarodnog privatnog prava, uključujući i dostignuća Haške konvencije o građansko-pravnim aspektima međunarodnih otmica djece, nastoje doći do najboljih rješenja kojima se reguliše sukob zakona i nadležnosti između država.

This article discusses the properties of concrete composite materials based on their contexture. Systematic and interactive approaches are required in order to achieve optimal material properties in the preparation of composite materials. In order to predict the physical and mechanical properties of each component of the composite material but also as a whole, its optimization, not only the mechanical but also the material properties under different working conditions, requires a combination of different methods and technologies. The advantage of each composite is its specific properties that cannot be achieved by any component of the composite material alone. The strength of the materials based on polymer concrete mixtures can be compared to the strength properties of metals. On the other hand, this material has elastic properties which give the material a high degree of flexibility. When compared to conventional materials, the value of polymer composites is assessed not only in terms of excellent mechanical properties but also in terms of their low weight and cost. The aim of the paper is to describe the advantages and disadvantages of composites based on polymer concrete mixtures.

Polymeric materials are commonly used for many purposes in Tissue Engineering Applications. In particular, they are used as scaffolds which are specially prepared in cell growth studies as well as drug loading and release systems. In drug delivery and controlled release systems functional, scaffolds are widely used in order to send the drug to its target region. On the other hand, in cell growth systems patterned polymeric scaffolds are prepared and used to allow the cells to grow at a certain region with a particular form. For this purpose, different techniques are used for the adhesion of cells onto the material surfaces. In this study, patterned scaffolds from various polymers as Polymethylacrylate (PAM), Polystyrene (PS) and polyvinylchloride (PVC) were prepared using micro contact printing with the soft Lithographic Technique. The prepared materials were morphologically analyzed and cell growth was followed by using electron scanning microscope (SEM). Poly (dimethylsiloxane) (PDMS) molds were prepared in different shapes and used as stamp materials to transfer the designed patterns. The cell growth on these patterned surfaces was followed after seeding L929 mouse fibroblasts cells. Neutral Red Uptake Assay was applied to observe cell growth. The cell growth experiments showed that the cells were attached to the patterned surfaces and a significant increase in cell growth on the surfaces were observed.
