Aims and background: Mining and energy complexes in Serbia are recognized as a major source of a large number of pollutants. Serbia’s environmental performance reports clearly indicate that large ...mining and energy complexes are the dominant source of air pollution. It is difficult to determine which of them remarkably threaten the quality of the environment, as all the basic elements of the environment (air, water, and soil) are threatened, not just one. Mining and energy complexes significantly reduce the quality of the immediate environment, as the distance areas throughout water and air pollution propagation. Additional motivation for this study lies in the fact that large mining and energy complexes are particularly interesting because they are located in the immediate vicinity or large rivers (mostly the Danube), which are protected in many national and international legislation acts (particularly the Danube). The basis for the preservation of environmental quality is an effective environmental management system (EMS) in mining and energy complexes. The aim of this study is to promote and elaborate the possibility for improving the mining and energy complex environmental protection/management system by applying the basic principles of sustainable development. Methodology: Project management methodology is selected as a tool. Project management is based on the application of a network planning technique (Critical Path Method), because of its suitability for representing the logical structure of environmental protection system. The survey was conducted in the area of the city of Kostolac. The examined area included mining and energy complexes in Kostolac, which incorporate three surface mines (Ćirikovac, Klenovik, and Drmno) and two thermal power stations (TE “Kostolac A” (100 MW) and TE “Kostolac B” (2 × 348.5 MW)). The PSR model (Pressures, State, Response) was used for the organization of the interactions within “society-environment” system as the basis for indicator selection. Results: Procedures to identify and determine the significance of the environmental aspects should be established by executive staff in mining and energy plants and complexes. Identification of environmental aspects is the first part of the planning system of environmental management and the activities related to them. The accomplishment of critical path activities represents the basis for improving the environmental protection system in mining and energy complexes. Discussion: Application of sustainable development principles depends on the country’s energy potential and the application of the adopted environmental policy regarding mining and energy complexes. Strict enforcement of existing laws and regulations presents an opportunity to rectify many shortcomings while providing economic benefits, restoring the usable value of ravaged land, and preserving air and water quality.
This paper explores the distribution pattern of SAR1g within the adult male
head during utilization of hands-free operation of contemporary mobile
phones as a source of electromagnetic radiation. The ...research assesses the
optimal positioning of the mobile phone by examining three distinct
orientations to determine the minimal SAR1g distribution compared to the
conventional talking position when hands-free feature is not utilized. The
analysis encompasses GSM bands operating at 900 MHz and 1800 MHz, depending
on the alignment between the mobile phone and the head.
This paper analyzes the specific absorption rate and the temperature elevation of the brain within an adult?s man head exposed to electromagnetic radiation. The source of electromagnetic radiation is ...a contemporary mobile phone operating at 900 MHz. Simulations were performed on an anatomically accurate AustinMan 2.6 voxel-based human model with a resolution of 1 ? 1 ? 1 mm3. The thermal analysis focuses on temperature distribution on the brain surface in fixed time steps during one hour of continuous mobile phone use.
Systems approach in safety is applied during the analysis of complex safety systems and identification of key performance indicators. The integration of the safety system is necessary to enable ...efficient use of safety resources, and to take into consideration all technical, human and organizational aspects of safety. Safety lifecycle is an engineering process designed to optimize safety system and increase the level of safety. The main advantage of applying this model in real systems is increasing the effectiveness of the protection of employees and goods and the efficiency of safety resource use. In this paper, we describe the model for safety performance assessment of integrated safety systems, based on selected safety indicators and safety lifecycle.
Efikasnost funkcionisanja sistema upravljanja zaštitom životne sredine u rudarskoenergetskim kompleksima zavisi od stepena sprovođenja usvojene politike zaštite životne sredine i primene preventivnih ...mera zaštite životne sredine. Nedostatak finansijskih sredstava za unapređivanje tehnologije eksploatacije, transporta, pripreme i prerade energetskih mineralnih sirovina u našim rudarsko-energetskim kompleksima, negativno utiče na ostvarivanje ciljeva zaštite životne sredine, a posledice radnih aktivnosti rudarsko-energetskih kompleksa dovode do smanjenja nivoa kvaliteta vazduha, vode i zemljišta. Upravljanje sistemom zaštite životne sredine bazirano na subjektivnim stavovima pojedinaca ukazuje na nepoštovanje principa održivog razvoja i narušavanja kvaliteta životne sredine. Primena standard ISO 14000 i savremenih metoda upravljanja zaštitom životne sredine predstavlja osnovu za unapređivanje procesa upravljanja zaštitom životne sredine. Višekriterijumsko odlučivanje zasnovano na analizi posledica radnih aktivnosti transformacije energije uglja i značajnosti aspekata životne sredine stvara osnovu za izbor prioritetnih preventivnih i korektivnih mera zaštite životne sredine. Cilj istraživanja je da se dokažu prednosti primene savremenih metoda upravljanja i energetskih indikatora u procesu odlučivanja, u odnosu na sisteme upravljanja bazirane na subjektivnim stavovima pojedinaca. U istraživanju predstavljenom u ovom radu, analizira se primena metoda AHP, BSC i energetskih indikatora. Cilj disertacije je da se modeliranjem sistema upravljanja zaštitom životne sredine u rudarsko-energetskim kompleksima stvori teoretska osnova za promenu načina organizacije sistema zaštite životne sredine, omogući smanjenje nivoa negativnog uticaja transformacije primarne energije uglja u sekundarnu, unapredi stanje životne sredine i predstavi jedan od mogućih načina rešavanja brojnih ekoloških problema. Praktičan doprinos istraživanja predstavlja razvijen model sistema upravljanja zaštitom životne sredine, koji se zasniva na savremenim metodama upravljanja.
