This research paper explains the importance of public relations and its role of public relations in textile organization. Public relations are the art and social science of that link inside and outside the organization together. PR in the textile industry plays a crucial role in building and maintaining a positive company image. The aim of this paper is to highlight the role and importance of public relations in creating a strong brand through effective communication with the public, customers, and partners. Additionally, PR strategies help in managing crisis situations and preserving the company's reputation. Effective PR can increase brand recognition, leading to higher sales and customer loyalty. Nowadays, as consumers become more aware of social responsibility, PR can contribute to promoting sustainable and ethical practices within the textile industry.

The most advanced form of public relations is represented by scientifically guided processes of solving organizational problems and change processes. This paper discusses some of the methods used to gather quantitative and qualitative information to define the problematic situation as accurately as possible. The primary purpose of research in public relations, like other business functions, is to reduce uncertainty in decision-making. This paper first examines the place of research in various models of public relations. It then explains the first phase in the PR management process-situation analysis-where research activities are particularly emphasized. The second part of the paper focuses on methods, both formal and informal, commonly used in PR practice.

For a long time, corporate identity, corporate image and corporate reputation have been studied from a number of academic perspectives, due to their intangibility and their significant role in gaining an organization's competitive advantages. Recent business circumstances (for example, the economic downturn due to the Covid-19 pandemy) bring new challenges for companies and their long-term survival. The aim of this paper is to review the constructs of corporate identity, corporate image and corporate reputation, and, thus, to remove or reduce the misunderstanding of the three constructs in the relevant literature. After a thorough theoretical review, some influential conceptual models were examined, pointing out the role of communication in the whole process of corporate marketing.

Numerous branches of industry, involving the textile and clothing sector, are subjected to various negative trends of the COVID-19 pandemic period and other crises. Crisis management in a systematic manner within a company represents one of the possible replies aiming at reducing the adverse effects of these events. The analysis of companies' experiences in encountering such an unwanted event shows that good communication facilitates crisis management. The main goal of this paper is to consider the role of public relations in the crisis management. The first part of this paper considers different forms of crisis that every production company has to take into account. The middle part of the paper focuses on the crisis management process, and, also, analyzes possible communication strategies. In the final part of the paper, attention is paid to the recent experiences in terms of crisis communication management in well-known companies.

Benchmarking represents a contemporary method which provides opportunityy for learning and change of behaviour based on comparison with the ones best in class. It creates a base for many developmental opportunities for the organizations which are capable to recognize benneffits from practical implementation of this method. Benchmarking has an important place in the development of new product, as well as services, of which a large proportion of small and medium-sized enterprises (SMEs) are still unaware. In initial phase of new product development, in the phase of idea generation, results of benchmarking analysis may affect the projection of success path of following phases of product development. Considering the process of development and marketing of new textile products raises the question of best practice of the process itself, as well as the role and place of benchmarking within the stages of the process of development of new textile products. The paper focuses on looking at modern product innovations marketed by organizations operating within the textile industry and drawing conclusions about the level at which the development of operational performance and the innovation incentive of organizations depends on the implementation of the benchmarking process in the process of developing new textile products.

Social responsibility is applied in many industrial branches around the world, and in recent decades, various aspects of corporate social responsibility have been analysed in the apparel and textile industry. The textile and clothing industry is rapidly developing branch of the industry, so modern corporations must be able to respond to market demands and place products on the market as soon as possible. In doing so, they must be aware of their environment and actors who are involved in the process in any way and must adapt their business in order not to cause harm to others and do not pollute the environment. However, in spite of the efforts of organizations to be socially responsible, we still meet today with textile and clothing companies, which behave very unethically towards their actors. As long as there is an opinion that the realization of a profit is on a far higher scale and that it is far more valued by employees, consumers, investors and other stakeholders, there will exist a problem of implementing a socially responsible business. Organizations tend to reduce all critical aspects that negatively affect the production itself and are often criticized by the community. They try to behave ethically towards all actors, but the unethical reflection in the business is present to a lesser extent. The aim of this paper is to study the textile and clothing industries through the prism of corporate social responsibility at the national level. Particularly important is the way companies in this sector are dealing with social responsibility issues.

This study examines success factors and motivation of entrepreneurs in the rural areas of the Eastern Serbia. The survey of the eighty entrepreneurs in the two municipalities has been conducted on the Zaječar district territory, and it included 14 villages. The weak economy, the depopulation process and the lack of financial sources are identified as problems, while the hard work and the quality of the products (services) are crucial success factors. On the other hand, political involvement had the lowest significance as the success factor. The results also indicate that the strongest motivators of the researched entrepreneurs were to be one's own boss and to increase one's own income.

Qualitative methods have an increasing importance and are increasingly used as one of the tools used to manage all types of organizations. The application of these methods brings significant advantages in conducting research. This paper presents an overview of the application of qualitative methods in management and the importance of using a combination of quantitative and qualitative methods in the research.

In this paper, the key features of observation, as a specific research method that is used to research various social phenomena (including business and marketing), have been considered. The study focuses on the advantages and drawbacks of this method during its application. Also, an observation method is compared to the other methods to collect data, especially to survey which uses recognizable measurement instruments (questionnaire and interview, first of all). This analysis has shown that observation, if it is conducted in a systematic way, may be a more objective method than the survey.

An extreme thermophilic, iron-sulphur oxidising bacterial culture was isolated and adapted to tolerate high metal and solids concentrations at 70°C. Following isolation and adaptation, the culture was used in a batch bioleach test employing a 5-l glass standard magnetic agitated and aerated reactor, for the bioleaching of a copper-lead-zinc collective concentrate. The culture exhibited stable leach performance over the period of leach operation and overall copper and zinc extractions higher than 97%. Lead sulphide is transformed into lead sulphate remaining in the bioleach residue due to the low solubility in sulphate media. Brine leaching of bioleach residue yields 95% lead extraction.

Archaeological site Felix Romuliana is located in Eastern Serbia, on the 10th kilometer of Boljevac - Zajecar road. It represents the remains of the Roman emperor Gaius Valerius Maximian Gallery’s palace. The value and importance of this unique monument, which dates from the late Roman period, are shown by the fact that in 2007. it was included in the UNESCO list of world cultural heritage. This paper introduces touristic - geographic location of Felix Romuliana, its artistic value, history and progress of archeological research as well as protection measures and site management system. The second part consist the tourist valorization results, made by Hilari du Cros model. Aim of the article is to determine the manner in which it is possible to make a presentation of cultural and historic values of the potential tourists (both domestic and foreign) and to point out the weaknesses and the opportunities in the tourist valorization. Finally, it can be concluded that the strategy for tourism development in this area should be based on the promotion of cultural tourism, which would be the holder of the Gamzigrad archeological complex.

Copper was precipitated using a sodium sulphide solution as the precipitation agent from an acid solution containing 17 g/l copper and 350 g/l sulphuric acid. The particle size of nearly 1 μm in the sulphide sludge sample was detected by optical microscopy. Based on chemical and X-ray diffraction analyses, covellite was detected as the major sulphide mineral. The batch bioleach amenability test was performed at 32°C on the Tk31 mine mesophilic mixed culture using a residence time of 28 days. The dissolution of copper sulphide by direct catalytic leaching of the sulphides with bacteria attached to the particles was found to be worthy, although a small quantity of ferrous ions had to be added to raise the activity of the bacteria and the redox potential of the culture medium. Throughout the 22-day period of the bioleach test, copper recovery based on residue analysis indicated a copper extraction of 95 %, with copper concentration in the bioleach solution of 15 g/l. The slope of the straight line tangential to the exponential part of the extraction curve gave a copper solubilisation rate of 1.1 g/l per day. This suggests that a copper extraction of 95 % for the period of bioleach test of 13.6 days may be attained in a three-stage bioreactor system.

The basic aim of this paper is to explore public relations practitioners' different perceptions of professional ethics depending on gender, age, educational level and years of experience. Analysis of professional ethics in Serbian public relations, has gained the ability to introduce all relevant aspects that should act in order to reach the positive developments and improve the existing situation in the field of ethics in public relations. The conclusion may be derived from this research is that business ethics in public relations in Serbia is at a high level. However, we must accept these results with caution, because very critical and sensitive issues of ethics lead to the interviewees to give fulsome answers that prove and practical examples. In order to obtain relevant results in future studies need to be, above all, changed the manner of conducting the survey. So, you need a personal approach with full respect for the respondents of anonymity. Business ethics in Serbia deserves much more attention and through education and research, as well as direct examples of business practice. .

The aim of this work is construction of equilibrium isotherms in solvent extraction. Technological parameters have been predicted for treatment of mine water by solvent extraction and electrowining. Two stages of extractions and one stage of stripping have been predicted for copper recovery by analyzing the equilibrium isotherms. The process was performed on mine water with 2,5 g/dm3 Cu2+, 3 g/dm Fe2+, pH 1,8, using 9 vol% LIX 984N in kerosene (organic solvent), with 95 and 98% stages efficiencies, respectively. This course produced an advanced electrolyte solution, suitable for electrowining and cathodic copper recovery, containing 51 g/dm3 Cu2+ and 160g/dm3 H2SO4 from a 30 g/dm3 Cu and 190 g/dm3 H2SO4.

In this work, technical and technological characteristics of pilot plant for biohydrometallurgical production of copper financed by Ministry of Science and Environment Protection of Serbia, in the frame of capital providing for scientific research for the period 2006-2008 is presented. Presented within this project is the contribution and capability of the Institute for Mining and Metallurgy Bor to carry out the Fp6 IP project: 'Biotechnology for Metal Bearing Materials in Europe (BioMinE)'. In the pilot plant, processes such as: microbiological leaching, pressures oxidation, chemical purification of solutions, solvent extraction and electrowining of copper were carried out. Bioleaching can treat complex copper concentrates which are either unacceptable to smelting or attract high penalties. Some of the elements penalized in smelting (for example zinc) are dissolved in the bioleach process and can be recovered for sale. This may often allow an increased recovery of a few percent in the production of the copper concentrate. Bioleaching can be used in either small or large cathodic copper production from copper concentrate. Bioleaching uses conventional upstream and downstream process technology and the unit operation itself has been proven in the gold industry. For these reasons, this work describes the pilot plant for biotechnological production of copper from RTB Bor resources.

In this work, autotrophic growth of mesophilic acidophiles from the Underground Copper Mine Bor was performed. Two selected solution samples collected from the 'Tilva Roš' ore body were prepared in a 9K nutrient medium (Silverman and Lundgren, 1959). The first sample TR k-16 was obtained during the hole drilling of the ore body, and the second TR k-31 from the drainage channel. Two samples of 9K media (Silverman and Lundgren, 1959) were inoculated with two selected solution samples from the underground mine Tilva Roš. Inoculated culture media were incubated without prior autoclaving in the period of 6 days at a temperature of 28 ?C with purging air through the system with enough oxygen and carbon dioxide. Oxidation rate of ferrous ions in the first 3 days of incubation was 14.8 and 10.7 wt.% Fe2+/day, the next 3 days 17.3 and 13.6 and for the total period of 6 days 98.3 and 74.8 wt.% for the first and second sample, respectively, i.e. 100 wt.% with initial percentage of ferrous ion in each medium. After centrifugation of enriched samples of culture media at 3000 rpm for 5 min, a plenty of mesophilic acidophiles were determined by microscopic method. According to Karavaiko [6], in the processes of incubition for 9K nutrient solution cells number reach a value of 108 cells/cm3.

International fresh water resources now occupy a prominent position in international affairs and are recognized as a legitimate concern of conflict studies. Numerous scholars, policy-makers, and activists alike have suggested broadening use of the security concept beyond its traditional geo-political and military forms to also consider environmental threats that seriously jeopardize human well-being. This article analyzes conceptual and theoretical arguments that have been made for the management of international environmental issues - such as, for instance, water disputes over international fresh water resources (rivers). Although the above assumptions about water conflict seem to be illuminating, there has been need of a more detailed explanation and understanding of cooperation over international rivers. However, the very conceptions of conflict and cooperation are ambiguous, and, not very convincingly handled in the literature. In contrast to conflict, cooperation - the main subject in this inquiry - receives less analytic attention, and, consequently, it is less understood as a concept. This study suggests a three-fold typology of cooperation: voluntary, induced, and imposed cooperation.

This article compares and contrasts current U.S. "war on terrorism" and proliferation of nuclear, chemical, and biological weapons (NBC’s) with the general U.S. foreign policy during the Cold-War and post-Cold War eras. The focus is primarily on a growing dilemma - "informal" or "formal" American empire - that rises from unprecedented asymmetry in military power between the United States and its closest followers. Also, this article analyzes the role of non-material elements of power (so-called soft power) and reviews recent views regarding the "unilateralism-multilateralism dichotomy" in American foreign policy. The author demonstrates that the "war on terrorism" and proliferation of NBC’s weapons show that U.S. status as the only super-power is not simply a matter of resource availability and relative power. Military muscle is an essential requirement, but it does not itself secure that position. This is especially true for the status of an empire either "informal" or "formal.".

The main aim of this research was to measure workers' perceptions of the four crucial success factors (commitment to safety, safety communication, the safety climate and learning from incidents) for Zero Accident Vision (ZAV) implementation by conducting a survey using a questionnaire given to four production plants in the Serbian military industrial complex. Almost 500 respondents participated in this survey with a response rate of over 90%. A possible influence of ethical leadership at work (ELW) and organizational commitment (OC) on ZAV enforcement was also examined. The reliability and validity of all of the measuring instruments were found to be acceptable. ELW was found to have a strong influence on ZAV implementation, whereas OC was found to have the mediating role in this relationship. [ABSTRACT FROM AUTHOR]

Food produced using an organic agricultural approach does not use conventional pesticides or synthetic fertilizers. Purchasing organic food is influenced by several factors. This study investigated the factors influencing young people from Serbia's intention to purchase organic food. Constructs from earlier research that have been demonstrated to have strong correlations with the desire to purchase organic food were combined in the study model. The database was created from a survey of 111 questionnaires completed by individuals in the 20--30 age range and structural equation modelling was conducted. The findings demonstrated that the most important factors influencing the purchase intention of young people in the country are health consciousness, food safety concerns and society. The study also showed that price sensitivity and environmental awareness had moderate but not negligible effects on purchase intention. [ABSTRACT FROM AUTHOR]
