Modelling of flicker in large real distribution networks has been a challenge until now, due to huge number of flicker sources contributing to total flicker levels in the network. In this paper, voltage flicker is modelled for a large real medium voltage (MV) distribution network. The total flicker is calculated from background flicker resulting from high voltage network and from flicker emission of a large number of sources in the analysed MV network. The flicker emission was modelled by statistical distributions of emission levels. Results of the simulation were compared to flicker measurements from several power quality monitors, installed in the feeders of the analysed MV network. The results show a significant similarity between the model and the measurements. Conclusion of this work is that the voltage flicker can be modelled with sufficient accuracy, even in large real MV networks.

The paper emphasizes that the period of beginning study is alarming, because through the new life circumstances, obligations and environment, great changes occur and a personal hierarchy of values and priorities of students in their lives is formed. The aim of the research was to determine eating habits and differences in relation to gender among students at the University of Tuzla. The research was conducted on a sample of 813 respondents, male and female students of the University of Tuzla. Eating attitude test (EAT26) is used for diagnosis of eating habits. Obtained results sowed statistically significant difference between male and female students in the applied test EAT26. Key words: EAT26, eating habits, students

This chapter provides an overview of research opportunities and issues in IoT forensics. It gives a quick introduction to forensics and digital forensics. Key specifics of IoT forensics are explained. Issues that arise from IoT related challenges in all phases of a forensic investigation are presented. Some opportunities that IoT brings to forensics are pointed out. An example of an IoT forensics case is provided. A detailed research overview is given, providing information on the main research directions with a brief overview of relevant papers. The chapter concludes with some ideas for future research.

1. BACKGROUND 1.1. Definition and Significance of Management As there is no universally accepted definition for management, it is difficult to define it. Father of scientific management, Frederick W. Taylor gave the following definition: “Management is an art of knowing what is to be done and seeing that it is done in the best possible manner.” A more elaborate definition was given by Henri Fayol (18411925), one of the most influential contributors to modern concepts of management. He considers a management as a process that comprises planning, organizing, staffing, leading or directing, and controlling an organization or initiative to accomplish a goal (1, 2). The verb ‘manage’ comes from the Italian maneggiare (to handle, especially tools), which derives from the Latin word manus (hand). The French word mesnagement (later ménagement) influenced the development in meaning of the English word management, that literally means to conduct, control and direct the affairs of a business, institution, etc. (1). The size of management can range from one person in a small organization to hundreds or thousands of managers in multinational companies. The success of any business depends heavily on the effectiveness of its managers. The significance of management is huge to that point that some people agree that in order to evaluate a company’s current and future worth, the most important factors are the quality and experience of the managers. 1.2. The Difference between Efficiency and Effectiveness Efficiency and effectiveness are both commonly used management terms. These words, while they sound similar and start with the same letters, are often considered synonyms. Yet they both mean different things. Efficiency refers to doing things in a right manner. Scientifically, it is defined as the output to input ratio and focuses on getting the maximum output with minimum resources (1). Effectiveness, on the other hand, refers to doing Professional paper, Received: Apr 05, 2021, Accepted: Jun 23, 2021, doi: 10.5455/ijbh.2021.9.97-104, Int J Biomed Healthc. 2021; 9(2): 97-104

Days of Academy of Medical Sciences of Bosnia and Herzegovina (AMNuBiH) this year was organized together with International Academy of Sciences and Arts in Bosnia and Herzegovina (IANUBIH) in Sarajevo, Bosnia and Herzegovina on December 4th, 2021. At this conference held two meetings: Symposium with title “Sciontometry, Citation, Plagiarsim and Predatory in the Scintific Publishing” and "SWEP 2021" with title "Design of Observational Clinical Studies" (1-4). Reasons for this titles werw very frequent cases in the academic and scientific publications about four mentioned topics of the Symposium in the Bosnia and Herzegovina and other countries in Balcan region, but also worldwide. Authors of the presentations at the conference came from Bosnia and Herzegovina, Croatia, Serbia, North Macedonia, USA and Poland. Days were organized as hybrid meetings: over twenty participants have been in conference room of the hotel Holiday in Sarajevo, over 50 participants followed presentations of the conference via zoom technology. Within presenters of thir experiences in the scientific area covered by title of this conference were some of most influential scientists from Bosnia and Herzegovina who are included between 2% of authors deposited in the Stanford scientometric list, which were published several months ago. Also, some of authors are former or current Editorsin-Chiefs of indexed biomdical journals in Bosnia and Herzegovina, Croatia, North Macedonia (Izet Masic, Asim Kurjak, Doncho Donev, Osman Sinanovic). Also, Sylwia Ufnalska and Izet Masic are or have been members bof the European Associacion of Scince Editors (EASE) and and they have great expriences about topic of this cnference (5, 6). Participants and titles of the presentations at the Symposium “Scientometrics, Citation, Plagiarism and Predatory in Science Publishing" were as follows: News, Received: Dec 08 2021, Accepted: Dec 26, doi: 10.5455/ijbh.2021.9.300-303, Int J Biomed Healthc. 2021; 9(4): 300-303
