In countries and regions with poor road infrastructure, this often means that the population outside major urban centres is even physically incapable of getting some sort of health aid in a timely manner. Being a country made up of a mainland territory and five islands in Gulf of Guinea, almost entirely covered by tropical rainforest, Equatorial Guinea is a showcase of various obstructions in developing effective health care system. The sustainable primary, secondary and tertiary health care assumes good accessibility as well as proper understanding of local conditions. The paper presents a model for sustainable health care building – a local hospital capable of providing all basic types of health service while retaining a high level of technical independence. The architectural design for a regional hospital was developed aiming to maxi...

The quality of the built environment largely depends on the quality of financier, in this case embodied in some kind of state/municipal authorities, committees and civil servants. In this paper, an example of the application of up to date high-tech design methods and technologies in the design and construction of public buildings is presented. Belgrade public buildings designed and constructed in the period 2009 – 2013, is shown. The first five projects for construction of energy efficient kindergartens (up to passive house standard) with the use of renewable energy sources and realised through architectural competition, were considered as a passing fad, but such a practice has become standard procedure for the design of the ...

Given that there is not much research on the safety and health of employees in local self-government units in Serbia and Montenegro, there is a need for the analysis of the protection provided by the applicable regulations in the countries of this part of Europe. The conducted research shows that the right to safe and healthy working conditions in local self-government units is governed by the regulations on workplace safety and health of those countries. It is desirable to improve the quality of legal protection which will contribute to the improvement of the workplace safety and health of these employees and will improve the quality of work in local self-governments.

The current situation in the area of water resources management in the Republic of Serbia indicates that the basic problems are insufficient construction of sewerage infrastructure in cities, i.e. insufficient coverage with the sewerage network of users connected to either public or private water supply network, followed by an insufficient number of constructed and operative wastewater treatment plants. In this sense, a particular problem is a requirement for relatively large initial investments in wastewater collection and treatment sector. Also, a special difficulty is the low price of delivered and channeled water within the existing system of public utilities, which is insufficient to provide maintenance of the existing water supply and sewage system...

Decontamination related to CBRN (chemical, biological, radiological, nuclear) events represents a set of processes and activities aimed at total or partial removal or neutralization of radiological, chemical, and biological contamination caused by an intended or non-intended threat, thereby reducing the risk of exposure to the people or the environment up to the permissible levels. The primary and ultimate goal of decontamination is the complete elimination of radioactive contaminants or the minimization of contamination levels of chemical and biological contaminants. The aim of this paper is to demonstrate the relevance of CBRN decontamination observed from multiple perspectives: the environmental resources protection standpoint, the society wellbeing standpoint, and the operative personnel and experience-knowledge standpoint to engage them in the most effective manner.

In addition to the definition of their ecological status, the existing problems of polluted water systems also require that parameters of the oxygen regime should be determined. The importance of monitoring the indicators of oxygen regime in rivers is aimed at achieving sustainable water management and preserving environmental quality. Oxygen regime in the Nišava river ecosystem is monitored based on specific physico-chemical indicators: biological oxygen demand (BOD), chemical oxygen demand (COD), total organic carbon (TOC), dissolved oxygen and oxygen saturation. The aim of this paper is to demonstrate the significance of oxygen regime indicators by monitoring their concentrations at measuring stations along the Nišava, which can help assess the quality of the given aquatic ecosystem. The paper relies on the Results ...

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.

The basic aim of this paper is to assess the risk to which workers - water treatment operators - are exposed to within water treatment plants, as well as to propose preventive measures in order to reduce the level of occupational risk. The applied methodology consists of system analysis, with in-depth literature review. The usage of appropriate occupational safety systems in the water treatment control processes leads to a double effect: a higher quality of treated water in shorter periods of time, with energy and material savings, as well as safer and healthier working environment. Key words: water treatment plants, occupational hazards, occupational risks, protection measures.

Most of the construction activities are performed in the big cities, encouraging major migrations from all sides of country to the dense urban areas. Developing new settlements on the outskirt of the city is the only way to prevent its collapse. However, these areas have no infrastructure needed for the purpose. The paper will present the case study of the construction challenges during the design and construction of the new settlement in Okolassi, local community 30 km distant of the capital Libreville. Different challenges like poor road infrastructure, lack of electricity, water and sewage, or non-existence of the skilful workforce, could transform even the simplest construction task in the insurmountable problem. Careful planning and designing are essential for the successful procurement and construction in the rainforest environment.

The aim of this paper is to monitor oxygen concentration demand by measuring stations along the river, and use these data to determine the ecological status of the Danube in Serbia. Indicator of the oxygen regime in the watercourse involves monitoring the concentration of biological oxygen demand (BOD-5) and ammonium ions (NH4-N), by monitoring state of the environment based on the load of surface water with organic matter and ammonium, respectively (Regulation on the national list of environmental indicators, "Official Gazette of the RS", no. 37/2011). The paper used the Ministry of Agriculture and Environmental Protection, Agency for Environmental Protection of the Republic of Serbia water quality ...
