Solution of Nonstacionary Thermoelasticity Problems
Kohut, Roman
The paper deals with a finite element solution of transient thermoelasticity problems. For each time step the system of linear algebraic equations is solved using the conjugate gradient method preconditioned by incomplete factorization of the matrix derived from the original matrix. The time step is chosen adaptively. The results of numerical tests are presented.

Assessment of Rockbursts parameters inferred from in-situ observations
Petroš, V. ; Holub, Karel
The aim of this article is to determine maximum stress due to seismic waves propagation through the rock mass. For this determination, rock density, velocity of seismic waves propagation vp and vs and ground amplitudes were introduced. For the evaluation data recorded at 3 underground seismic station from the time period 1993-2002 were used. To this set of data only rockbursts with some consequences in mine were included. Based on these analyses, predominant frequencies of seismic P and S waves, dependences of ground amplitudes to scaled distance and stress at the head of seismic wave were calculated.

Marginalization of moravian-slovakian borderland.
Vaishar, Antonín ; Zapletalová, Jana
After the split-up of Czechoslovakia, a new state border came into existence between Czech and Slovak republics. Regions, initially interior, became border ones. Creation of new state border and transition to the to the market economy multiplied by physico-geographical characteristic of the territory leads up to the rapid marginalization of this „new“ borderland. The paper deals with marginalization of the Bílé Karpaty region, namely with case studies of Bojkovice, Horní Lideč, Slavičín, Brumov and Valašské Klobouky micro-regions.

Měnící se funkce zemědělství v malých městech během 20. století (na příkladu Klimkovic)
Martinát, Stanislav
This contribution deals with changes in the Czech agriculture and its changing functions during the 20th century. This research problem is followed on the example of small town of Klimkovice. In the first part influences of agriculture on small towns are assessed, the second part is devoted to changes in Klimkovice. Final part concludes contribution with possibilities for prospected development of agriculture in small towns.

Problematika druhé a třetí fáze reformy územní veřejné správy v České republice (na příkladu Jihomoravského kraje)
Klusáček, Petr
The paper deals with the topical issues connected with the public administration reform in the Czech Republic. On the one side the attention is paid to the problems of creation of the administrative regions of municipalities with extended competence and on the other side to the issue of size of municipalities in the Czech Republic. Possible further topics of research are outlined in conclusion; the possible positive influence of e-government in improved efficiency of the public administration is pointed out here.
