SPORT CLUBS INTERACTION WITH THE FANS USING SOCIAL MEDIA COMMUNICATIONS. CASE STUDY AT SCM CRAIOVA

Today, the process of communication has come to be seen all together differently to how it was viewed a few decades ago, because contemporary society has greatly changed the way people interact with each other. Communication has stretched its arms to all areas, starting with businesses, where the human relations sector is quite important, up to sport organizations in which communication with the fans is essential. Organizations in all areas have become aware of the need for communication, realizing the strategic role that communication plays in achieving goals. The communication strategy is the defining lines of the organization’s attitude and conduct in order to achieve its communication goals and thereby performance goals. The paper aims to present some theoretical aspects regarding the notions of social media and the connection between social media communications and the sports clubs, emphasizing how this connection leads to the increase of the awareness, with a practical example at the handball club SCM Craiova. REZUMAT. Interacțiunea cluburilor sportive cu fanii folosind comunicarea prin social media. Studiu de caz la SCM Craiova. Astăzi, procesul de comunicare a ajuns să fie privit în totalitate diferit față de modul în care a fost văzut în urmă cu câteva decenii, deoarece în societatea contemporană s-a schimbat foarte mult modul în care oamenii interacționează unul cu celălalt. Comunicarea și-a întins brațele în toate domeniile, pornind de la sfera afacerilor, unde sectorul relațiilor umane este destul de important, până la organizațiile sportive în care comunicarea cu fanii este esențială. Organizațiile din toate domeniile au devenit conștiente de nevoia de comunicare, realizând rolul strategic pe care îl joacă comunicarea în atingerea obiectivelor. Strategia de comunicare reprezintă liniile de definire a atitudinii și comportamentului organizației pentru a-și atinge obiectivele de comunicare și, prin urmare, obiectivele de performanță. Lucrarea urmărește prezentarea unor aspecte teoretice privind noțiunile de social media și legătura dintre comunicarea prin social media și cluburile sportive, subliniind modul în care această conexiune conduce la creșterea notorietății, prin prezentarea unui exemplu practic la clubul de handbal SCM Craiova.

A New Hybrid Inductor-Based Boost DC-DC Converter Suitable for Applications in Photovoltaic Systems

A new hybrid step-up converter suitable in applications where large conversion ratios are needed is presented. The topology is still simple, containing only one transistor and three diodes. A detailed dc and ac analysis is performed and all design equations are provided. Compared to other topologies of the same type, the proposed converter exhibits lower or equal current and voltage stresses. A state space model is provided including the conduction losses and based on it the audio susceptibility and the control to output function are derived. As the converter is still of second order with the control to output transfer function exhibiting a right half plane zero, controller design is practically the same like in a Boost topology. It is shown how the proposed converter can be used in a photovoltaic system for performing the maximum power point tracking algorithm using the perturb and observe method. All theoretical considerations are verified through simulation and finally validated by practical experiments
