V. Ira: The changing intra-urban structure of the Bratislava city and its
perception. Geografický časopis, 55, 2003, 2, 2 figs., 4 tabs., 44 refs.
This paper aims to provide a basic picture of changing intra-urban structure
of Bratislava in the transitional period of the 1990s, and its perception. The
most significant processes contributing to the changes in the intra-urban
structure in the five zones within the city (historical core, inner city, villa
neighbourhood, housing estates, and the periphery) are briefly presented. The
basic features in the perception of transformational changes by urban dwellers
(university students) are identified and "the images of transformational
changes" are discussed. The challenges posed by urban development, and its
perception are summarized. Key words: urban change, Bratislava, intra-urban
structure analysis, urban environment perception, sustainable development

J. Szőllős: The role of natural gas in recent development of the energy
system of Slovakia. Geografický časopis, 55, 2003, 2, 6 figs., 7 tabs., 27
refs.
The aim of the paper is to evaluate the present role of natural gas in the
energy system of Slovakia and its potential contribution to sustainable
development of energetics in the context of regional development. Natural gas
will presumably be the main energy source in transition from use of not
renewable to renewably energy sources. Natural gas as an exhaustible resource is
not sustainable. With regard to the possibility of its application in small
facilities, gasification helps regional development and represents a stimulus
and determining factor for location of additional economic activities and
increase of the population's life quality.
Key words: natural gas, energy system, sustainable development, Slovakia

Ľ. Solín: Conception of regional hydrogeography of Slovakia. Geografický
časopis, 55, 2003, 2, 1 fig., 2 tabs., 28 refs.
The paper contains conception of regional hydrogeography of Slovakia which
leans on six regional units complying with condition of "regionality"
with regards to long-term hydrological balance. Comprehensive characteristics of
regional units is based on regional values of hydrological and
physical-geographical characters which cover not only the size of hydrological
balance components but also genesis and quality of runoff and take into the
account the key problems rising from the relationship between the runoff and
land cover or economic activities carried out in basins of regional units.
Key words: regional hydrogeography, regional unit, hydrological balance,
comprehensive hydrological characteristics

J. Minár: Midmountain level in the West Carpathians as tectoplain:
outline of the work hypothesis. Geografický časopis, 55, 2003, 2, 4 figs., 36
refs.
Paper deals with possible explanation of the rise of regional planation
surfaces in active orogens. Polygenetic planation surface relatively rapidly
created in conditions of prevailing extension (subsidence) tectonics of young
orogens is defined as tectoplain. Its rapid rise is due to tectonic downthrow of
big part of the block under erosion basis, rapid retreat of fault slopes,
expansive abrasion in transgressive regime, local sediment deposition that
together with tectonic erosion eliminates isostatic compensational uplift.
Forming of tectoplain is alternative hypothesis of the West Carpathians
midmountain level creation in Miocene. Twelve verification/falsification
procedures are formulated as a basis for corroboration (confutat-ion) the
hypothesis. They contain analysis of spatial distribution and character of the
Neogene sediments, fission track analysis, analysis of spatial relationships of
denudation and accumulation remnants of tectoplain, and construction of complex
dynamic model of regional evolution.
Key words: planation surface, tectoplain, West Carpathians, landscape
evolution, denudation chronology

J. Urbánek: Geomorphological map: a sum or a system? Geografický časo-pis,
55, 2003, 2, 4 figs., 20 refs.
The study points to the fact that compilation of geomorphological map can
lean on one of two hypotheses. It is the hypothesis that a set of mapped forms
is a sum (aggregate) or hypothesis that this set is a system (set of interacting
forms). The study describes the geomorphological mapping based on hypothesis
that the set of mapped forms is a sum. The author analyses in detail syntactic
and semantic aspects of such mapping and concludes that the majority of
geomorphological maps reflecting the territory of Slovakia were compiled on the
principle of a sum.
Key words: geomorphological map, geomorphological analysis, sum, syntax,
semantics, classification
