Restoration of landmarks hit by rising moisture is in conjunction with the concept of sustainability by a very current theme. This problem needs to be addressed from a global point of view. The article discusses individual remediation technologies (invasive and non-invasive), which were applied and long-term investigated on several historical buildings within Slovakia. It describes the costs of their implementation, efficiency rate and importance from the perspective of the preservation of the nation’s cultural heritage and from the perspective of sustainability and the possibility of using these objects. From the perspective of sustainability, it is also shown that some interventions helped with remediation of the moist structure. This step results in a positive impact on the surroundings and protection of persons located in the vicinity of these buildings. It also helps to sustainability in terms of an environmental point of view because the demolition of renewed buildings is not necessary. The Article conclusion notes the level of efficiency of individual technologies. It also provides recommendations that could also be applied to many other historic buildings.

Educational Paths

Geological paths (geopaths, geotrails) represent a type of educational paths that connect sites which are interesting from the Earth-sciences point of view. These sites (e.g. outcrops, old quarries, historical buildings built of local stone or viewpoints) often represent the links between geodiversity and other phenomena within a region (which is in accordance with a holistic approach to geotourism). Thus, they can give complex information not only about the abiotic nature but also about biodiversity, history or culture of the region, usually through narrative. Suitable interpretation of geodiversity and its relationships to the biodiversity and cultural heritage allows to identify regional specifics, it helps to find the mutual connections between particular phenomena within the region and it supports the holistic perception of a given region. The contribution presents an example from the Brno city where the urban geopath can be used for teaching regional geography of Brno and its surroundings.

A sampling selection methodology using buildings facades of Pelotas/RS - a city located in the south of Rio Grande do Sul – are developed. Pelotas heritage is considered one of the most representative of eclectic architecture from Brazil. This sampling selection methodology alternative is based on framing, selection and buildings exclusion considering different solar orientations, typologies, damage degrees, among others. The properties list of Pelotas is presented in Cultural Heritage Inventory and Zona de Preservação do Patrimônio Cultural (ZPPC), following preservation level described in the City's III Master Plan. Some other constraints considering city morphology were also considering. Regarding the results, Pelotas mostly presents ground floor buildings, painted with mortar cover, and destined for services. Cracks, dirt and paint detachment were the main pathological manifestations found in Pelotas historical buildings. Although Pelotas presents many inventoried historic buildings protected by legal means, their cultural heritage condition recognition no guarantee the building's permanence over the time. Moreover, sampling methodology proposed in this study can enhance and systematize surveys in field studies and does not disqualify the properties. This development denotes an innovation to be certainly applied in other historic cities.

ABSTRACTDevelopments in non-invasive analytical techniques advance the preservation of cultural heritage materials by identifying and analyzing substrates and media. Spectral imaging systems have been used as a tool for non-invasive characterization of cultural heritage, allowing the collection of chemical identification information about materials without sampling. The Library of Congress has been developing the application of hyperspectral imaging to the preservation and analysis of cultural heritage materials as a powerful, non-contact technique to allow non-invasive characterization of materials, by identifying and characterizing colorants, inks and substrates through their unique spectral response, monitoring deterioration or changes due to exhibit and other environmental conditions, and capturing lost and deteriorated information. The resulting image cube creates a new “digital cultural object” that is related to, but recognized as a distinct entity from the original. The range of data this object contains encourages multidisciplinary collaboration for the integration of preservation, societal and cultural information.

Current developments in the area of neuroenhancement pose multiple ethical and societal questions. Improvements in general cognitive capacities can have important positive effects. With the use of several interventions, ranging from pharmaceutics through microsurgery to non-invasive and invasive methods, new possibilities of enhancing human abilities can be achieved. Yet, they have to be critically evaluated from the point of view of both individual and societal consequences that are involved. The aim of this paper is to address societal benefits and challenges that are related to these interventions. These new developments, especially in the specific area of their military application, pose important questions with regard to safety of their use, long-term results, coercion to use them, and issues of inequality. Often, these consequences are unforeseeable at the present moment and can greatly interfere with development of both individuals and societies. Therefore, as in both areas – civilian and military – the long-term consequences are still difficult to predict, prudency is prescribed. Consequently, any use of the methods of enhancement should be under exceptional scrutiny from the ethical as well as legal and social point of view.

Maintenance and restoration of historical buildings are an important contribution to sustainability of cultural heritage. Refurbishment should be adopted to preserve the essential features of the building ́s history and cultural heritage. Reconstruction of internal plaster in historical buildings belongs to important treatment in a landmark area. Plaster of historical buildings is usually characterized by an open porosity, which makes it sensitive to the degradation caused by physical and chemical agents. Alterations and structural faults can lead to invasive interventions which modify permanently the cultural value and the structural behavior of the buildings, in conflict with necessary preservation requirements.Knowledge of the historical building interior microclimate is essential for the definition of suitable reconstruction. Computer simulation plays major role in determining air flow, which can cause negative influence within historic buildings such as high level of moisture, fungus, chemical reactions etc. In order to prevent deterioration of plaster and to retard their decay, protective products – nanofibers – could be applied on the historical surfaces. Using nanofibers should cause minimal modifications to the historic appearance and protect from negative influences.

Summary. The prevalence of malignant neoplasms of the oral cavity occupies a significant place in the structure of oncological diseases while the cancer treatment is mainly complex and radical. Reconstructive surgery is most often associated with removable dentures. The patients after an upper jaw resections take a significant part of patients with postoperative defects. There is still no consensus between the specialists on prosthetics for patients after resection of the upper jaw of oncological origin. The literature shows a large number of problems, the main one is the lack of data on the long-term outcome of the prosthesis of these patients, the «temporality» of the prosthetic constructions and the poor prognosis. From this point of view, the use of high quality elastic materials is a successful for current problems resolution. The work describes the correction method of an upper jaw resection prosthesis by means of an elastic pad. The high-potency of the Ufi Gel P VOCO (Germany), A-silicone based material, was demonstrated for the clinical relining of resection prosthesis in distant future. We succeeded to achieve effective denture adhesion by correcting the peripheral flap along the transitory fold and the A-line with Ufi Gel P elastic material. The elastic correction of resection prosthesis allows to provide emergency help, makes the use of the prosthesis more comfortable, catalyzes the adaptation and has a positive impact on the social rehabilitation of cancer patients. Key words: elastic pad, upper jaw resection prosthesis, post-resection distant ptosthetics.

The results of experimental studies of masonry on the action of dynamic and static (short-term and long-term) loads are presented. The possibility of plastic deformations in the masonry is analyzed for different types of force effects. The falsity of the proposed approach to the estimation of the coefficient of plasticity of masonry, taking into account the ratio of elastic and total deformations of the masonry is noted. The study of the works of Soviet scientists revealed that the masonry under the action of seismic loads refers to brittle materials in the complete absence of plastic properties in it in the process of instantaneous application of forces. For the cases of uniaxial and plane stress states of the masonry, data on the coefficient of plasticity obtained from the experiment are presented. On the basis of experimental studies the influence of the strength of the so-called base materials (brick, mortar) on the bearing capacity of the masonry, regardless of the nature of the application of forces and the type of its stress state, is noted. The analysis of works of prof. S. V. Polyakov makes it possible to draw a conclusion that at the long application of the load, characteristic for the masonry are not plastic deformations, but creep deformations. It is shown that the proposals of some authors on the need to reduce the level of adhesion of the mortar to the brick for the masonry erected in earthquake-prone regions in order to improve its plastic properties are erroneous both from the structural point of view and from the point of view of ensuring the seismic resistance of structures. It is noted that the proposal to assess the plasticity of the masonry of ceramic brick walls and large-format ceramic stone with a voidness of more than 20% is incorrect, and does not meet the work of the masonry of hollow material. On the basis of the analysis of a large number of research works it is concluded about the fragile work of masonry.
