Landscape is an area formed by the interactions between humans and nature, which bring various characteristics to the area. Landscape Character Assessment (LCA) methods enable more accurate description, mapping, and evaluation of features within the landscape. Also, landscape characterization and classification is facilitated by the advances of Geographic Information Systems (GIS), which constitute a very efficient tool for analysis and overlay mapping. This paper explores and tests an application of Landscape Character Assessment (LCA) methodology at a regional scale in Ziban region, Algeria, combining natural and cultural attributes using GIS. The first stage of overlay of attributes is followed by the verification of draft map involving a visual assessment on-site in order to develop the final classification and assessment describing each landscape character area and type. The study results show that Ziban region has a rich structure with diversified landscapes created by unique natural and cultural landscape values composed of 36 different character areas and 19-character types. The main contribution of this research consists in developing a typology for Ziban landscape and providing useful results for decision-making related to the future management of landscape character in the Algerian context, which has undergone strong pressure related to urbanization, industry, transport, desertification, and tourism.

This paper is focused on clarification of the basic principles for the establishment of an innovative approach in the field of landscape research through its application in spatial planning documents in Ser-bia. The key question is: how the practice of considering landscape character could direct new spatial arrangements, based on the development of strategic spatial planning documents? The paper describes the results of analysis undertaken during the development of the "Spatial plan for a special-purpose area The Cultural Landscape of Sremski Karlovci". The landscape character assessment was the main methodology taken to define value of landscape character as the starting point for defining border of cultural landscape and "representative landscape units", as well as for guiding sustainable land use management which is opposed to the traditional approach of land-use decision making. Based on landscape character value, this research provides the elements for creating a different conceptual framework for spatial planning in Serbia which is one of the most effective model of the implementation of the European Landscape Convention.

Krakow is a city of high landscape values, which has found confirmation in the entry onto the UNESCO heritage list. Its cultural landscape requires protection and clarification within the context of intensive tourist use and a rapid pace of urban spatial development. For preservation protection and restoration of landscape values, the city authorities undertook work on the creation of a Cultural Park in the Stradom and Kazimierz districts, providing a comprehensive, sustainable, and multidisciplinary approach to natural, cultural and visual values of the urban structure. The article presents the application of the method of research on visual values in order to protect individual scenic resources of the historical urban structure. It is one of the analytical studies of a comprehensive protection plan project. This project defines the scope, framework and methods of development and management of a Cultural Park. The task of the visual analysis was to identify, characterize and evaluate the visual resources. It created a visual framework for further development of the historical district while preserving its local spatial identity. The studies resulted in a division into zones according to their nature and intensity of activities as well as outlining protection zones and intervention zones adjusted to individual characteristics of those places. An original method combining achievements of the method of landscape and visual assessment (LVIA) as well as achievements of the Krakow School of Landscape Architecture (KSLA) in terms of cultural landscape assessment was used for the research. The applied method provided guidelines to support sustainable project decisions regarding further development of the district for the preservation of local spatial identity. Its universal character creates possibilities for its application into the plans of other Krakow districts and is intended to be applicable to both urban and rural structures.

The aim of the study was to examine the usefulness of The Picus 3 Sonic Tomograph to assess the health state of trees of monumental sizes, which are an important part of the cultural landscape. In the study there were selected tree species Tilia cordata, Gingko biloba and Ulmus glabra growing in the vicinity of Lublin in different habitat conditions. Changes in the internal structure of the tree trunks were shown on the colour tomograms. Two tested specimens of Tilia cordata located in Radawiec Duży were intended to be cut down due to the construction of the ring road of Lublin. This made it possible to compare the obtained tomograms with the actual state of the inside of tree trunks after cutting down the examined trees. The results of Picus tomography Ulmus glabra and Gingko biloba growing in the historic park in Czesławice were confirmed by a visual assessment of trees. In each case the number of installed sensors influenced the image resolution and accuracy of the obtained tomograms. Diagnostics using sound waves is important in assessing the state of health of each tree, but it is especially recommended for testing of valuable trees. It allows for early diagnosis and selection of such protective actions to reduce to a minimum the destructive impact study on the body of the plant.

The main goal of this paper is to introduce the importance of landscape typology in present times when many landscapes are exposed to dynamic human impacts such as land use changes, urbanization, intensive agriculture, forestry or industrialization. Different approaches to landscape typology in Czechia and other European countries as well as relations of landscape typology to landscape character assessment and the European Landscape Convention are discussed. A requirement of a new exact and applicable landscape typology is a great challenge for Czech geographers.

Objective of the Review: To analyse the modern methods for assessment of the implantation potential of embryos in assisted reproductive programs. Key Points. We present the study results for selection of a most optimal embryo for transfer, using visual assessment of embryo quality, preimplantation genetic aneuploidy testing, analysis of metabolomic, proteomic, transcriptomic profiles of culture media and embryo blastocele. We have paid special attention to assessment of small non-coding RNA (sncRNA) in embryo culture medium. Conclusion. Due to the high sensitivity, objectivity and biomarker resistance to degradation, the most promising non-invasive method to assess the implantation potential of an embryo is analysis of the sncRNA profile in embryo culture media. Keywords: aneuploidy, pre-implantation genetic testing, small non-coding RNAs, proteomic analysis, metabolomic analysis.

Summary123I-N-ω-fluoropropyl-2β-carbomethoxy-3β- (4-iodophenyl)nortropan (123I-FP-CIT) single photon emission computed tomography (SPECT) can be evaluated by both visual assessment and quantitative analysis to assess the striatal dopamine state in vivo. The aim of our study was to investigate if visual assessment according to a predefined image grading scale reflects the results of quantitative assessment techniques. Patients, methods: 195 patients with a clinical diagnosis of idiopathic Parkinson's disease (n = 134), atypical parkinsonian syndrome (n = 47) or essential tremor (n = 14) were examined with 123I-FP-CIT SPECT and included in this retrospective study. Results were analysed according to predefined visual patterns of dopaminergic degeneration and graded as normal (grade 5) or abnormal (grade 1–4) independently by three raters. Quantitative two-dimensional (2D) operator-dependent, manual and three-dimensional (3D) operator- independent, automated approaches were used for quantitative analysis of the specific 123I-FP-CIT tracer binding ratio (SBR) for caudate and putamen. Results: Sensitivity, specificity, PPV, NPV and diagnostic accuracy of visual assessment of 123I-FP-CIT SPECT for the diagnosis of a neuro degenerative Parkinson's syndrome were 99%, 86%, 99%, 86% and 98%, respectively. Visual assessment and quantitative analysis agreed well in evaluating the degree of dopaminergic degeneration. Significant differences (p < 0.001) were found between degeneration patterns. Only between the so-called eagle wing degeneration and the normal pattern no significant differences in SBR caudate and putamen were found, neither by the quantitative manual (p = 1.00; p = 0.196) nor by the quantitative automated method (p = 1.0; p = 0.785). Inter-rater agreement for visual assessment was substantial for all possible pairs of the three raters (κ = 0.70 to 0.74). Strong correlations were observed between the quantitative manual and quantitative automated methods for quantification of SBR caudatum (r = 0.920, r2 = 0.846, p < 0.001) and SBR putamen (r = 0.908, r2 = 0.824, p < 0.001). Conclusion: Visual assessment was highly consistent with the results obtained by quantitative analysis and showed a substantial inter-rater agreement between experienced and inexperienced raters. Our findings indicate that visual assessment might be a reliable analysis approach for clinical routine.
