This paper concentrates on the area of special educational support provided to individuals living in homes for people with disabilities in the Czech Republic and presents partial research results illustrating the state of the provision of speech therapy to users of social services facilities falling under the jurisdiction of the Ministry of Labour and Social Affairs. The subject of the research is an analysis of support for the development of the communication skills of pupils living in social services facilities. The partial results of the research outline the approaches employed by the managerial staff of the given facilities in implementing special educational procedures, describe forms of speech therapy provision in homes for people with disabilities, and compare the attitudes of teachers and social services staff to the development of communication with the importance attributed to it by speech therapists and demonstrated by the case studies performed.

The mining boundary ultra-layer & cross-border of some small coal mines in the profit-driven results in a many of safety accidents, waste of resources and environmental damage while the state can not achieve the full uninterrupted supervision because of the backward monitoring tools and equipment. In this situation the real-time monitoring system for underground mining activities is designed based on explosion source location technology. Small and medium-sized coal mines tunnel by blasting operations. The P waves are picked up by acceleration vibration sensors buried underground that are identified and dealt by using wavelet transform. The bursting point is located by the Geiger algorithm and displayed in the mine’s electronic map. The monitor system has good stability, small positioning error by field-proven.

The article analyzes historical monuments as instruments of Russia’s attempts to impose its aesthetic hegemony in the post-Communist world. Drawing on case studies from the Czech Republic and Estonia, it argues that this hegemony is precarious and vulnerable due to inability to deal with the inherent ambiguity and complexity of historical events and figures. The Russian approach regards historical truth in absolute terms and is underpinned by a zero-sum game understanding of historical narratives. It does not tolerate a multiplicity of perspectives on history and has no appreciation for postmodernist deconstruction of historical symbols. This conflicts with a more diverse, reflexive and inclusive politics of memory as an intrinsic element of cityscapes of Prague and Tallinn where some of the controversial monuments connected with the Soviet occupation have been removed. Russia’s reaction to these changes reveals an inherently vulnerable nature of its aesthetic hegemony which is deeply dependent on recognition of the absolute nature of its historical truth that the monuments are supposed to embody.

Abstract During long-term research (almost forty years) of tailings containment in Chvaletice (Eastern Bohemia) were also carried out studies on the role of each plant dominants in succession. This review presents the most interesting results of these studies.

NIOSH researchers have been examining underground coal mining activities in order to evaluate work crew hazards. In 1994 a continuous mining machine operator was killed by falling roof during extended cut mining. Many aspects of the incident were used by NIOSH researchers to develop a scenario interview. The goal was to provide a realistic framework for acquiring frank and detailed insights. The interview consists of two sections. The first describes the underground mining conditions. The second recounts the fatal incident. Each section is supplemented by a diagram and a set of questions addressing relevant safety issues. The interview was administered at three mines that actively take extended cuts. Researchers found the scenario approach to be an effective interview tool as well as an effective hazard awareness and safe work practices training platform.
