Предмет рада јесте употреба Интернета за пословање предузећа. Актуелност ове теме проистиче из чињенице да у новој дигиталној ери могућности и предности електронског пословања и електронског трговања чине значајан потенцијал који треба искористити на најбољи и најефикаснији начин. Циљ рада јесте да укаже на предности Интернета за пословање са једне стране што штеди време, а на другом месту је и новац. Али овакво пословање путе интернета има и озбиљну сметњу заживљавању онлајн шопинга јер представља недовољну сигурност онлајн трансакција. Људи се и даље нерадо одлучују да број своје кредитне картице пошаљу преко мреже или сајта. Посебно је наш народ у Србији, претежно на Косову и Метохији специфичан по склоности информаци- оним технологијама и поверење у интернет пословање. Хипотеза рада јесте да је пандемија COVID-19 променила понашање потрошача и предузећа на тај начин што се већина њих преусмерила на интернет пословање. Помоћне хипотезе рада јесу да је Интернет тржиште једно од највећих светских тржишта у развоју и друга помоћна хипотеза јесте да уколико постоји квалитетна понуда, корисници се лако одлучују на куповину путем Интернета јер она подразумева већи избор, једноставно поређење цена између више продавача те услугу доставе на кућна врата, што значи уштеду времена. Међутим, реално је очекивати да се у блиској будућности превазиђе и овај проблем, пошто технологија и у овој области веома брзо напредује. Прво питање, које се поставља при извођењу трансакција, јесте питање поверења у оне са којима се посао обавља. У електронским трансакцијама, пословање се одвија између две или више страна, које су физички раздвојене. Оно што они који нуде производе и услуге морају да обезбеде јесте поверење купаца и корисника услуга. У раду биће примењене Опште научне методе: анализа, синтеза, индукција, дедукција, компаративна метода, статистичка, историјска метода, и друге методе иманентне друштвено хуманистичким наукама.

The thematic conception of the work consists of legal issues of special forms of control of state administrative in Bosnia and Herzegovina (at the state level, the level of federal units and districts). The paper analyzes the structure of bodies that perform this type of control, starting with the ombudsman institutions (Ombudsman for Human Rights of Bosnia and Herzegovina, Ombudsman for Children of Republic of Srpska), and with special reference to the institutions of auditors (of which there are four in Bosnia and Herzegovina). The author will present the organization of these institutions, the election of their members (ombudsmen and auditors), the way they act, and the possibilities they have, as well as the legal mechanisms they can use to protect both citizens and the public interest.

Rad se bavi pitanjem zaštite interesa djeteta u postupku institucionalnog zbrinjavanja u dom za djecu bez roditeljskog staranja kroz implementaciju principa „najbolji interes djeteta“ u centrima za socijalni rad. Namjera autora je bila da se, kroz kvalitativnu analizu, izvrši analiza slučajeva smještaja djece u ustanovu socijalne zaštite kao i metodologije i postupaka koji se sprovode u socijalnoj zaštititi u tim slučajevima. Istraživanje je provedeno prikupljanjem i analizom spisa u Centru za socijalni rad Derventa. U radu je prikazana deskriptivna analiza obilježja slučajeva izdvajanja 26 djece iz 14 porodica u periodu od deset godina (2010 – 2020), te intervencije organa starateljstva. Rezultati su ukazali na zaključak da su djeca izmještena iz razloga postojanja ugroženosti porodičnom situacijom, te da donošenju te odluke prethodi niz opsežnih stručnih postupaka i intervencija. Na kraju je istaknut značaj procjene stručnih radnika organa starateljstva vođenjem principom „najbolji interes djeteta“, te naglašena potrebu unapređenja sistema zaštite djece bez adekvatnog roditeljskog staranja u smislu kadrovskih promjena, sistemskih saradnji, razvoja deinstitucionalizovanog zbrinjavanja djece i unaprijeđenja sistemske podrške porodici.

A modern marketing system is based on supply, market conditions and regulated institutions. Defined as a pillar of the rule of law, the authority and strength of institutions depends on political stability, legal solutions and the rule of law, efficiency of the public administration system, corruption, civil liberties, but also commitment to philosophy and marketing concepts. Unfortunately, Bosnia and Herzegovina has not yet established an appropriate system in any of these areas and it is obvious that there is a significant gap between the situation in this area in our country and in the developed world. The rules according to which the socioeconomic structure is regulated, as well as the institutions and related institutions, do not form a system that, in accordance with modern principles of developed economies, provides efficiency and support for economic activities, and contributes more strongly to the goals of modern and democratic socio-political system. Marketing, with the philosophy of its approach, strongly determines economic and social trends, so that the developed marketing concept in the institutions of the system is one of the conditions for stability and progress of the country. The aim of this research is to point out that marketing in the security structures of Bosnia and Herzegovina is small and insufficient, that it is not at the level that provides the best in the society and shows us the outcome of such a situation for security and development processes in the community.

We understand circular economy as an economic system that aims to eliminate waste throughout an entire value chain – including manufacturing, production and use. Circular economy is also a way of rethinking our approach to waste and to every single stage of a products´ life cycle. Slovakia has been challenged recently to keep up with the changes the automotive industry is undergoing, including the green and digital transformation. The automotive industry producers have to accelerate innovations based on the required transition towards circular economy, an alternative to the unsustainable linear model of economy. The paper focuses on the principles of circular economy, demonstrated by the example of the Slovak automotive industry. The aim of this paper is to evaluate the current state of use of circular economy aspects in the automotive industry in Slovakia. We found out practical approaches of circular economy incorporated by Slovak automotive producers. In context of circular economy, Slovakia perceives prospective transition to automotive electrics industry, the introduction of new progressive technologies and sophisticated production. 

In all areas of society, it is necessary to actively and continuously act on unique (constitutive) rules that apply equally to all and perform non-selective and unprivileged regulation, coordination, organization and limitation of human behavior. These are institutions that can best present their functions. Economics has clearly shown how the real (and even virtual) economic reality works in principle and determined that the role of institutions in society and economy is not only necessary and unavoidable, but also a priority, as a metabasis and meta-mechanism. This paper presents a study of the impact of constitutional (political) rules, economic rules and contracts on the construction of socio-cultural capital. The aim of the research is to prove that all development models that have ignored institutions have proved unsustainable. The constitution has the role of preventing arbitrariness, ie “rule without rules”.

Managing the efficiency of a company and, in connection with that, the choice of the way of measuring efficiency is becoming more and more important, especially in the conditions of a modern business environment characterized by complexity, dynamism, uncertainty and heterogeneity. The company, in addition to being in different business environments, also has its own specifics, so the question arises what it means for a particular company to be efficient and what is an adequate model for measuring the efficiency of that company. In general, a good efficiency measurement system involves a set of performance measures, that is, a metric that quantifies efficiency and effectiveness. The paper presents a review of traditional and new integrated models for measuring the performance of enterprises in the function of control.

Heavy metals are considered to be one of the major contaminants of water in recent years due to their non-biodegradable property; hence making them toxic and bioaccumulate to living organisms. Conventional methods such us chemical precipitation, physical treatment through ion exchange are used for removing heavy metal ions from water. These methods are expensive and attributed to incomplete metals removal and high cost of treatment. In recent years, researchers have found alternative low cost and effective method for removal of toxic metals through biosorption process using biological materials. Moringa oleifera seeds is one of the biological materials which has effective adsorption capacity for removal of heavy metals from water and wastewater. In this article, the seeds of Moringa oleifera seeds as a low-cost biosorbent for removal of heavy metals is presented. Moringa oleifera seeds is inexpensive material that contains amino acids. The amino acid is a major constituent of the functional groups that aids in greater ability of heavy metals removal through metal ion exchange or complexation, which is mainly affected by pH, biosorbent dosage, and contact time. Moringa oleifera seeds residues have a greater capacity to absorb heavy metals in a single solution compared to multi ion solution.

Marketing in tourism is a systematic adjustment of tourism company policy and political policy at the local, regional, national and international levels in order to meet the needs of tourists and make a profit. The purpose of the paper is to explain how direct marketing, especially as part of a marketing mix, can help facilitate the exchange process in the international and domestic tourism markets. The aim of studying marketing in tourism is to make this concept available in this activity in theoretical, methodological and application terms. Marketing in the tourism industry is in a phase of maturity and is becoming sophisticated, which leads to the fact that the entire industry increasingly accepts the basic principles of marketing: The concept of marketing; Marketing orientation; Meeting the wishes and needs of consumers; Market segmentation; Value ; Product life cycle and Marketing mix (the principle on which the essence of the work is based). Direct marketing activities are based on databases and interactive communication media. Databases enable the selection of the target market (customer), which is acted upon by selecting the appropriate advertising/sales medium. The most famous media of direct marketing are certainly catalogs, direct mail and telephone (telemarketing), while in practice many others are used such as: television, radio, Internet, mobile phones, print, inserts.

Nowadays is important to increase power efficiency in the heat production sector. Tubes with shaped internal surface are one of the possibilities to improve efficiency of heat exchangers. In the fact of this is actual to look on the improvements of the process of forming from the perspective of the tool construction. Presented article is focused on mechanical analysis of the rotating mandrel for cold forming of tubes with shaped internal surface. As a proposed material of the tool was selected heat-treated tool steel. Analyses were performed with selected configuration of the bearings. One bearing was configured as radial and second bearing was configured as radial-axial. A result shows stresses in the mandrel and deformation of the mandrel under a load of forming pressure. Obtained results have potential to enhance knowledge in the area of construction of the forming tools.
