Abstract Prevalence of cognitive disorders is high in maintenance hemodialysis patients. Montreal cognitive assessment (MoCA) is used for detecting and evaluation of cognitive disorder degree in this patient population. In examined patient population, only 5 (12.5%) of them had normal cognitive function (MoCA ≥26). Mild cognitive impairment (MoCA 18-26) was found in 65.9% (29) patients, while moderate cognitive disorder (MoCA 10-17) was detected in 6 (21.6%) patients. Major cognitive disorder wasn’t detected in examined population. Statistically significant correlation was not established between laboratory parameters and overall MoCA score. Statistically significant correlation, however, was established between MoCA item that evaluates space and time orientation and intermediate secondary hyperparathyroidism and space and time orientation and severe secondary hyperparathyroidism. Hemodynamic instability during hemodialysis and silent ischemia of the brain are increasing risk of appearance of cognitive disorders in maintenance hemodialysis patients.

The city of East Sarajevo is a newborn city, formed twenty years ago, after the war in Bosnia and Herzegovina, in the area of the former southern and eastern Sarajevo municipalities. Changes that oc-curred in this area were not only administrative-political.Thepopulation moved from one area to anoth-er place, and changed in number and structure, which has resulted in significant changes in land use and land cover types. The aim of the paper is to analyze the types of land cover in the area of East Sarajevo using methods based on remote sensing, in order to find out the degree of these spatial changes in the period from 2000-2012, and also to define spatial development trends. Within the European project of remote research of land cover types and forms of land use, namedCO-RINE Land Cover (CLC),spacious facilities were identified from middle and large scale spatial resolution, with 5 first-level classes, 15 subclasses, and 44 subclasses of the third level of cover. Analyzing the area of East Sarajevo there are identified 3 of the first-class level, 10 second-class, and 16 third-class level types. Geodataare related to three observation periods: 2000, 2006, and 2012, comparing the situation at the beginning of the period with the situation after 12 years.

The worst flooding that ever hit Bosnia was in May 2014. The official estimates indicate that over 1.5 million people were affected in Bosnia and Serbia after a week of flooding. The assessments of the damage in Bosnia go up to €2billion of euro. The loss in floods is estimated 5 to 10% of GDP (as per WorldBank estimate). The effective floodplain management is a combination of the corrective and preventative measures for reducing flood damage. These measures require integrating data from a variety of sources, including zoning, subdivision, or building requirements, and the special-purpose floodplain ordinances.There are varieties of tools to generate a flood forecasting model to identify the potentially affected zones, so as to prioritize for remediation or the damage assessment. Furthermore, it is possible to analyze the time-related data and to explore trends and phenomena, to conduct the historical analysis and ―what–if‖ scenarios, and to track and monitor events such as excessive rainfall, track water levels, etc. Bosnia is just starting to develop these tools and methods and this could be the way to improve capability to tackle such natural disasters. This paper describes some applications of Remote Sensing (RS) and Geographical Information Systems (GIS) in identifying flood hazard zones and flood shelters and are therefore important tools for planners and decision makers. The purpose is to describe a simple and efficient methodology to accurately delineate flood inundated areas, flood-hazard areas, and suitable areas for flood shelter to minimize flood impacts.
