“…Numerous theories about the preservation and restoration of historic sites have emerged. Among these theories is the "organic restoration" theory by Wu [27], the "self-organization model", the "urban catalyst theory", the "organic micro-circulation restoration model", the "small-scale progressive model", and the "environmental micro-restoration model" [28,29]. Theories about the preservation and renewal of historic sites have appeared with their bases on the statuses and characteristics of historic sites in specific periods, so classifications should be made with a view to the specific stage of research on preservation and renewal for solving related problems in more effective and targeted manners.…”

The preservation and restoration of historic sites is of great significance to the continuation of a city’s historical heritage and high-quality development. However, the conservation management of historic sites is still in the stage of exploration and improvement. The current states of development and preservation have been facing many problems, such as fragmented and poor states of preservation. It is crucial to retain and revitalize the authenticity of historic sites. A multi-criteria decision-making approach to an innovative evaluation model is proposed. Based on the cultural, social, and economic characteristics of the historical sites, an evaluation index system is constructed and weighted to judge its importance. The results suggest that the statuses of the historic relics at the facet layer have the most significant effect on the preservation of the authenticity of historic sites. The completeness of historic relics ranks first in weight among the evaluation indexes, which suggests that emphasis should be not only on their protection, but also on the preservation of their overall styles. The results will enable urban decision makers to effectively set the priorities of preservation and restoration by regions and stages. Huai’an, a major ancient city along the Beijing–Hangzhou Grand Canal in China, was taken as an empirical case study to validate the feasibility of the evaluation index system and its ability to provide references for the preservation and restoration of historic sites.

“…For example, there are studies looking at the differences in land use and its changes between Eastern and Western Europe, such as more changes due to less stable political regimes in Eastern Europe (Kupková et al, 2013;Rusu et al, 2020), and prominence of changes like urbanization (Kupková et al, 2013;Petrişor et al, 2020) and cropland abandonment (Baumann et al, 2011;. The core principle allowing for comparisons across Eastern European countries is the fact that countries within the area share a communist background followed by a post-communist transition, often related to the European Union accession (Legutko-Kobus et al, 2023; Nowak et al, 2022), and, as a result, more centralized planning systems (Stan, 2021(Stan, , 2022bSlave et al, 2023).…”

This comparative study aims to test the hypothesis according to which environmental awareness of planners is crucial to sustainable cities with a healthy and well connected green infrastructure able to provide ecosystem services. To test the hypothesis, we compared two cities, Bucharest (Romania) and Chisinau (Moldova), based on quantitative analyses using CORINE land cover and use data to analyze the land structure and its dynamic, and qualitative analyses focused on the planning process. Our findings suggest that both cities share a decreasing interest for planning for their green infrastructure, which was lost and fragmented. The process was aggravated in Bucharest by post-communist property restitution. Based on the results, we recommend planners in post-communist countries to give more attention to the green infrastructure, in order to produce plans fitted to the welfare and sustainability needs of people.

Multimodal retrieval has gained much attention lately due to its effectiveness over uni-modal retrieval. For instance, visual features often under-constrain the description of an image in content-based retrieval; however, another modality, such as collateral text, can be introduced to abridge the semantic gap and make the retrieval process more efficient. This article proposes the application of cross-modal fusion and retrieval on real in vivo gastrointestinal images and linguistic cues, as the visual features alone are insufficient for image description and to assist gastroenterologists. So, a cross-modal information retrieval approach has been proposed to retrieve related images given text and vice versa while handling the heterogeneity gap issue among the modalities. The technique comprises two stages: (1) individual modality feature learning; and (2) fusion of two trained networks. In the first stage, two self-organizing maps (SOMs) are trained separately using images and texts, which are clustered in the respective SOMs based on their similarity. In the second (fusion) stage, the trained SOMs are integrated using an associative network to enable cross-modal retrieval. The underlying learning techniques of the associative network include Hebbian learning and Oja learning (Improved Hebbian learning). The introduced framework can annotate images with keywords and illustrate keywords with images, and it can also be extended to incorporate more diverse modalities. Extensive experimentation has been performed on real gastrointestinal images obtained from a known gastroenterologist that have collateral keywords with each image. The obtained results proved the efficacy of the algorithm and its significance in aiding gastroenterologists in quick and pertinent decision making.
