It is undeniable that corporate social responsibility (CSR) occupies an important place in managerial practice, but also in academic circles. Due to the strengthening of competition between companies, and the constant need for companies to be sustainable in a market and innovative sense, it becomes clear that it is necessary to integrate social responsibility into the company's business. Corporate social responsibility activities, which will be the subject of analysis, are in theory synthesized in the form of economic, legal, ethical and philanthropic activities. These corporate social responsibility activities should intuitively lead to building a positive reputation for the company. Reputation is an intangible but long-term investment. In the modern economy, where due to the speed of information transfer, it is very difficult to hide something, building a reputation is seen as one of the basic challenges of any company. The research focuses on the connection between the activities of corporate social responsibility and the reputation of large companies in the Federation of Bosnia and Herzegovina. Therefore, the paper analyzes the perception of managers about the connection of corporate social responsibility activities with the reputation of large and medium companies in the Federation of Bosnia and Herzegovina. The main goal of this paper is to examine the perception of managers about the relationship between corporate social responsibility activities and the reputation of companies in the Federation of Bosnia and Herzegovina.

In today's dynamic business environment conditions, the socially responsible business occupies a special place. Socially responsible companies are more sensitive to the needs and expectations of the most important stakeholder groups: shareholders, employees, customers and the community. In addition to socially responsible companies working in accordance with the needs and expectations of mentioned groups, they can achieve many other benefits from corporate social responsibility: gain a better reputation and image in the market, attract quality human resources, attract many investors, etc. Application of socially responsible business in companies requires from managers proactive approach, stakeholders orientation and ethical behavior in making business decisions. When we talk about socially responsible business, in theory, there are three types of managers: immoral, amoral and moral type. Immoral type of managers actively opposes what is considered correct or ethical. The amoral type of managers is neither immoral nor moral. Their main characteristic is that they are not too sensitive to the fact that their business decisions can affect others. The moral type of managers uses ethical norms and adhere to high standards of good behavior. This paper researched the dominant type of managers, from the aspect of socially responsible business, in large private companies in the Federation of Bosnia and Herzegovina. The research determined that managers, who are not too sensitive to the fact that their business decisions can have harmful consequences for others, are the dominant type of managers in large private companies in the Federation of Bosnia and Herzegovina. The research was proven on 63 large private companies in the Federation of Bosnia and Herzegovina.

Corporate social responsibility implies the company's commitment to create and implement business strategies and activities in harmony with the environment and ethical behaviour towards stakeholders. Employees belong to the important interest groups and resources of every company, because their actions directly affect business results. The paper presents activities of corporate social responsibility towards employees. Employee motivation is important because it directly affects the productivity of workers , which further has consequences on the business results of the company. Employee motivation changes in the action of various factors from the employee's environment , inside and outside the work environment. In this paper, corporate social responsibility will be presented as a factor related to employee motivation. The main goal of this paper is to examine the relationship between corporate social responsibility and employee motivation and the possible connection between socially responsible activities toward employees and their motivation. The research will be conducted by examining the attitudes of managers about the connection between socially responsible business and motivation, because managers make decisions about employees within their work activities. The sample includes managers of large Bosnian companies.

| The aim of this study was to morphologically describe the air sac system in Rosy-faced parrots (Agapornis roseicollis) and provide useful data for future veterinary care and treatment of respiratory system diseases in these pets. The research was conducted on five birds. In order to obtain the casts of the air sacs, we applied the corrosion cast technique, where we used the 26% solution of Vinylite mass. The research showed that the anatomy of the air sacs in these parrots was very similar to that in other birds, but there was some specific characteristic regarding the arrangement and connection between the air sacs. In Rosy-faced parrots we identified nine air sacs, the one unpaired, saccus clavicularis and paired saccus cervicalis, thoracicus cranialis, thoracicus caudalis and abdominalis. The casts showed that clavicular and cranial thoracic air sacs established a connection through the diverticula sternalia. These anatomical characteristics can be common to birds from Psittaciformes order and additional research need to be performed to confirm these findings.

Leptin is a hormone secreted from adipose tissue (AT) that plays important role in metabolism of carbohydrate, proteins, and lipids. Also, leptin and its receptors are key regulators of body weight and energy metabolism. Previous studies, demonstrated that plasma leptin improved glucose and lipid metabolisms independently of the food intake reduction by decreasing in blood glucose and insulin levels as well as triacylglycerol stores in the body. Objective of this study was to evaluate the relationship between plasma leptin concentration and lipid profile in healthy and diabetic individuals. Twenty-six participants were recruited in the study, 13 newly diagnosed and non-treated Type 2 diabetes (T2D) patients and 13 healthy controls. Metabolic variables including glucose, glycated hemoglobin, lipids: total cholesterol, triacylglycerol, high density lipoprotein, low density lipoprotein and very low-density lipoprotein, and hormone concentrations leptin and insulin were measured. Plasma leptin concentration was an increased significantly (p<0.001) in diabetic patients compared to controls. Values of other biochemical characteristics were significant different between cases and controls (p<0.001). A significant association was demonstrated between leptin with BMI levels in participants (p<0.05) but not between leptin and lipid levels (p>0.05). Also, strong negative associations were observed between leptin and glucose levels among controls (p<0.009) as well a positive association leptin with HOMA-IS in diabetics (p<0.05). These results suggest that plasma leptin concentrations were affected by the increased levels of glucose, insulin and lipid profile in Bosnian study population. Therefore, leptin can be used as a biomarker of glucose and lipid control in newly diagnosed diabetic patients.

The purpose of this study was to evaluate the relationship between knee extensor and flexor muscles strength and vertical jump in professional female volleyball players. Forty-one female volleyball players participated in this study. Isokinetic PT and was measured at 60°/s, whilst CMJ performance using a force plate. The participants were later divided to WG (weaker group - PT/BW<2) and SG (stronger group - PT/BW>2). Isokinetic concentric knee extension and flexion PT was significantly correlated with CMJ performance. However, higher correlation coefficients were obtained at the non-dominant leg. No significant differences were found but mere trend favoring non-dominant leg muscles in the weaker group. Strong positive correlation exists between isokinetic knee PT and CMJ height in professional female volleyball players. When divided and compared to WG and SG the results indicate weaker players tend to modify their technique individually and towards unilaterality as so they could maximize their performance.

Retrieval Number: 100.1/ijeat.E28430610521 DOI:10.35940/ijeat.E2843.0610521 Journal Website: www.ijeat.org Abstract: Humans are generally exposed to a variety of pollutions present in the air they breathe, the food they eat or in the water they drink. Some of the most dangerous pollutions are metals and heavy metals. These are naturally occurring substances which are harmless when present in the environment at low levels. However, due to many pollutants such as industry processes or war activities, the heavy metal concentration can exceed the limit of tolerance and become very toxic for the natural environment and living organisms in it, including humans. Unlike organic pollutants, the heavy metals (as ions and as particulate matter) once introduced into the environment cannot be biodegraded and remain there indefinitely. By rainfall these pollutants can be partially transferred from air or soil into the rivers and drinking water sources, where they accumulate in even higher toxic levels. The high concentrations of heavy metals in contaminated natural water reservoirs have an impact on the microbial community composition which resides there. This type of water pollution can cause the changes in life cycles of natural bacterial populations, influencing their metabolic processes and proliferation. The presence of pathogens in water is normally indirectly determined by the testing for “indicator organism” such as coliform bacteria. Coliforms are usually present in larger numbers in contaminated water and at the same time they are indicators of whether other pathogenic bacteria are present, too. In crisis situations, like war or some natural disasters, where trusted sources of drinking water are not available anymore, the military and residents of affected areas are forced to use some alternative water resources that cannot be tested for their microbial or metal contamination properly. Therefore, the existence of some fast test that would detect not only dangerous bacterial pathogens in water, but also the presence of metals and heavy metals as well, would be of great help and importance for the human health. Even though the number of pathogens can be drastically reduced by the boiling of water, the heavy metals are not destroyed by high temperature. Hence the main objective of our work was to optimize the biosensor chip for microbial detection in contaminated water that would serve at the same time as an indicator for the chemical composition of the water,
