In the distribution area of Novi Sad, owned by ODS EPS Distribucija, there are 35 substations 35/10kV that are on average over 50 years old. Considering the tendency to gradually eliminate the voltage levels of 35kV and 10kV in this distribution area and the transition to the voltage level of 20kV, some of these substations are planned for reconstruction into 20kV distribution plants. Reconstruction of these substations requires large financial resources, because their construction part is in a very bad condition, electric power equipment is unreliable and difficult to maintain, and operational readiness is an increasingly important factor in presenting successful business. During the reconstruction of these transformer stations, the possibility of a backup power supply route for electricity customers, the speed of intervention and the smooth performance of preventive maintenance must be taken into account. The appearance of reclosers opened a new chapter in the world of electricity. Namely, now the above problems and requirements can be solved in a simpler and cheaper way with the use of reclosers. The paper will present a proposal for the reconstruction of the substaion 35/10 kV "Kuzmin" in the area of the Branch Distribution Sremska Mitrovica, which has been operating for more than 60 years, in an external 20 kV distribution plant formed with the help of reclosers built on steel lattice poles. The proposed solution can be used to solve the same or similar problems, primarily in the distribution area of Novi Sad.

Growing environmental problems and increasing requirements of green jobs force universities around the world not only to transform their curricula but also to enrich existing ones with contents related to the promotion of sustainable development. This paper aims to show the importance of measuring and monitoring the share of green contents in all university activities, as only in that way it is possible to monitor trends and give realistic assessments of their effect and importance. The paper presents a comparative analysis of different types of methodologies for assessing sustainable activities at universities as well as research conducted at the University of Novi Sad in Serbia and its comparison with the University of Gothenburg (Sweden). This research aims to point out the importance of increasing competitiveness in higher education through assessment of green content in a curriculum and its promotion. In this way, through eco-labeling methodology, it would be easier to identify those contents that, in a certain share, contribute to the promotion of sustainable development. Furthermore, this methodology can easily be extended across the country and the region, which would bring positive effects to all stakeholders in higher education.

The World

Our world with its high technologies has long been deeply dependent on the quality of electricity supply. In most countries of the world there are national power grids that combine the entire set of generating capacity and loads. This network provides the operation of household appliances, lighting, heating, refrigeration, air conditioning and transport, as well as the functioning of the state apparatus, industry, finance, trade, health services and utilities across the country. Without this utility, namely electricity, the modern world simply could not live at its current pace. Sophisticated technological improvements are firmly rooted in our lives and workplaces, and with the advent of e-commerce began the process of continuous transformation of the way individuals interact with the rest of the world. But with the achievement of intelligent technologies, an uninterrupted power supply is required, the parameters of which exactly meet the established standards. These standards maintain our energy security and create a reliable power system, that is maintaining the system in a trouble-free state. Overvoltage is the deviation of the rated voltage from the value of the corresponding quality standard (frequency, sinusoidal voltage and compliance of harmonics). Overvoltage in terms of fire hazard is one of the most dangerous emergency modes of electrical equipment, which causes conditions that in most cases are sufficient for the occurrence of fire hazards (exceeding the allowable voltage leads to disruption of normal operation or possible ignition). Against the background of deteriorating engineering systems, increased power consumption and poor maintenance, power supply of electrical installations, the main causes of overvoltage in electrical networks are thunderstorms (atmospheric overvoltage), switching switches, uneven phase load in electrical networks, etc. The physical picture of internal overvoltage is due to oscillatory transients from the initial to the established voltage distributions in the conductive sections due to the different situation in the electrical circuit. In the conditions of operation of electric networks planned, mode or emergency situations are possible. Therefore, the ranges of overvoltage are determined by the range from several hundred volts to tens and hundreds of kilovolts, and depend on the types of overvoltage. Atmospheric overvoltage is considered to be one of the most dangerous types of emergency modes of operation of the electrical network. This overvoltage occurs as a result of lightning discharge during precipitation by concentrating electricity on the surface of the object, the introduction of potential through engineering networks and

Huge financial resources are spent in the construction industry all over the world, which are frequently wasted largely due to a lack of proper planning. In recent decades, in an attempt to overcome challenges, various contractual and administrative systems have been used by construction owners/clients. One such system has been Integrated Project Delivery (IPD). Its implementation has, however, experienced drawbacks. Identifying such drawbacks is an initial step in attempting to resolve them, and this paper aims to identify and prioritize the IPD implementation drawbacks in the context of the Iranian construction industry. A comprehensive list of IPD implementation drawbacks is prepared using a questionnaire survey. An in-depth literature review of the IPD concept has been combined with a review of various case studies applying the IPD system. The results were analyzed using the Robust Exploratory Factor Analysis (EFA) method. 22 drawbacks in the Construction Industry were categorized under four themes; contractual, environmental, managerial, and technical. Results show that contractual drawbacks are the most significant. The implication of this research is that identifying and classifying IPD implementation drawbacks provides a useful reference to managers and owners of the construction industry, for identifying and codifying solutions to overcome them.

The development of orthopedic surgery in Novi Sad and Voivodina is related to the name of Dr. Katherine MacPhail, a Scottish physician, who came to Serbia during the World War I, where she worked with her mission in Belgrade and Kragujevac. After the war, she remained in Serbia and, in 1921, founded the first children's, co-called English-Serbian Hospital; then, in 1934, established English-Yugoslav Children's Hospital for Treatment of Osteoarticular Tuberculosis in Sremska Kamenica, which was open until 1941. After the end of World War II, as early as in 1947, Dr. MacPhail returned to Sremska Kamenica, where she reactivated the hospital. After the nationalization of the hospital, she left for Scotland, but the hospital kept working, first under the supervision of the Belgrade Clinic for Orthopedic Surgery and Traumatology, and then as a ward of the Clinic for Orthopedic Surgery and Traumatology of the Novi Sad School of Medicine, until 1992, when it was closed.

The Advanced Technical School from Novi Sad set up a completely new study group for web design in 2004. The paper explains its organization and gives course descriptions. When it was established, there were not many similar groups in the world exclusively dealing with web design, whose programs could serve as role models, hence the curriculum and syllabus had to be based on our own experience. They cover inevitable web issues like usability, user-oriented web design, accessibility, privacy and security, which are briefly discussed in the paper. The purpose of the research referring to web accessibility and privacy presented in one of the sections was to help create the two documents. The students' prior knowledge was also an important parameter in their writing. The curriculum and syllabus have been updated recently, and the improved version given herein will be in use from the next academic year.

The innovative management today is to promote and support organizational strategic goals through the rational use of material, labor and financial resources. The main goal of innovative management in libraries is to build the management system which enables focused search of options, development and implementation of novelties to increase the library’s competitiveness and sustainability and, in its turn, the sustainability of the environment. The specific features of innovations in the library and information sphere are as follows: comparatively rare radical while frequent modernizing innovations; consistency and systemacity (change in any element inevitably changes the library system overall); irreversibility. To assess the value of library innovations, the author suggests to apply the following criteria (characteristics) correlated with the world experience: innovative relevance, financial effectiveness, cultural efficiency, social significance, global sustainability. Each criterion has its own weight while the expertise has to be accomplished within the suggested procedure. This methodology enables to assess the library knowledgeably. It was tested thrice by expert teams – participants in the All-Russia Contest of Library Innovations initiated by the Russian State Library in 2013, 2015, and 2019.
