The study area is located along the western continental margins of South America, Peru-Chile Trench south-east Pacific Ocean, geographically encompasses 90° to 60°W longitude and 55°S to 0° latitude. The study aims to perform a spatial analysis using GRASS GIS approach applied for processing and visualizing topographic and geophysical data on the study area. Data include following raster grids: topographic SRTM_15PLUS raster grid with 15 arc-second resolution, geoid model (EGM96), geophysical fields and gravity maps (marine free-air gravity and vertically corrected free-air gravity). The thematic grids were mapped by GRASS GIS modules and visualized for comparative analysis. Spatial analysis included plotting slope aspect, profile curvature, terrain elevation and modeled topographic classes based on the neighborhood analysis. The results include visualized geophysical and topographic maps of the study area showing correlation between the geophysical fields and topographic elevation. The variety of forms of the submarine relief of the Pacific Ocean seafloor was formed as a result of complex factors: tectonic movements, dislocations, active volcanism, geologic variations in rock density, which is reflected in visualized gravity and geoid maps. The actuality of the study is explained by high potential commercial interests in deep-water mineral resource deposits, oil and gas, which make ocean seafloor studies one of the most promising topics in geoscience. At the same time, the need for programming applications for big data analysis in geosciences requires testing advanced scripting approaches in cartography. Therefore, the current paper presents a multi-disciplinary approach combining geological analysis with technical cartographic aspects of data analysis and visualization.

The paper focuses on the spatio-temporal analysis of the dynamics of the incidence in the population in Lviv region by the main classes of diseases for 2009-2018. Groups of factors influencing the incidence in the population and the demographic situation in general have been investigated. It was found out that each group of factors can have positive and negative effects in certain regions. The structure of the disease incidence in the population of Lviv region by classes of diseases for the period 2010-2018 has not changed. It is traditionally formed by diseases of the respiratory system, blood and blood-forming organs, circulatory system, endocrine system and neoplasms. The quantitative indicators of changes in the incidence in the population of the region until 2018 by the main classes of diseases in the context of administrative districts are calculated and analyzed. A cluster analysis was carried out to determine the spatial differentiation of the incidence in the population of Lviv region. For clustering, the main indicators were selected by classes of diseases that have the largest specific weight in the structure of morbidity. The cluster analysis made it possible to distinguish two clusters within the region, for which the characteristics in the population morbidity indicators were identified. The analysis of variance (LSD-test) showed the presence of significant differences between the incidences in the population in Lviv region on respiratory diseases. The study of the disease incidence in certain areas makes it possible to predict the state of health and to work out measures to improve the health in the population.

The climate change on a global, regional and local scale is one of the largest problems indicated by the 21st century studies. Some of the major climate changes on the Balkan Peninsula, and in particular in Bulgaria, are related to rising temperatures and decreasing precipitation, which leads to drought and climate aridity. The present study focuses on the investigation of the climate aridity in the non-mountainous part of Southern Bulgaria in order to assess the aridity condition in temporal and spatial scale. The main investigated period is 1961-2015 and the reference periods are 1961-1990 and 1986-2015. The aridity is analysed on the basis of monthly data for air temperatures and precipitation from eight meteorological stations by calculation of De Martonne aridity index and Emberger Index. The survey shows that in all the analysed meteorological stations in Southern Bulgaria there are periods which display characteristics of the semiarid or arid climate. The aridity is well-expressed in the southwest part of Bulgaria (station Sandanski) and the western part of the Thracian lowland (station Plovdiv). Despite the aridity conditions established in the investigated region the tendencies in multiannual variability of De Martonne and Emberger indices show decreasing of aridity during the last 30 years (1986-2015) of the investigated period.
