• Sommario/riassunto: This book is a Printed Edition of the Special Issue that covers research on symmetric and asymmetric data that occur in real-life problems. We invited authors to submit their theoretical or experimental research to present engineering and economic problem solution models that deal with symmetry or asymmetry of different data types. The Special Issue gained interest in the research community and received many submissions. After rigorous scientific evaluation by editors and reviewers, seventeen papers were accepted and published. The authors proposed different solution models, mainly covering uncertain data in multicriteria decision-making (MCDM) problems as complex tools to balance the symmetry between goals, risks, and constraints to cope with the complicated problems in engineering or management. Therefore, we invite researchers interested in the topics to read the papers provided in the book.

• Sommario/riassunto: Geological Heritage has very diverse elements, both for its intrinsic nature and for its social and scientific significance. These elements have a scientific dimension (stratigraphic, geomorphological, lithological, paleontological, etc.) and a landscape dimension, both with implications for territorial management. In territorial management and planning, it is essential to carry out inventory and cataloging of places of natural and social interest to establish a comprehensive policy. The identification and valuation of the geological and biological heritage, and their interaction in the landscape should favor the conservation and preservation of this natural and historical heritage. Sustainable development implies rational use that prevents the degradation or loss of these unique environments of the natural environment as well as a dissemination and awareness of landscape resources for a better understanding and enjoyment, integrating activities of both environmental education and nature tourism.The diversity of a territory is the result of the complex and continuous interaction of the geological substrate (geotopical) and biological factors that model the existing ecological and evolutionary processes at the level of genes, species, ecosystems, and landscapes and that are expressed in a characteristic representation of organisms adapted to these factors. These vary according to the spatial dimensions and the temporal scales considered, in a wide range, that goes from the geological processes that involve millions of years and vast territories to the casuistic biotic, ; and anthropic events that can occur in an instant in any territorial sector.

• Sommario/riassunto: The landscape of minimally invasive urological intervention is changing. A lot of new innovations and technological developments have happened over the last 3 decades. Laparoscopy and robotic surgery have revolutionised kidney and prostate cancer treatment, with more minimally invasive procedures now being carried out than ever before. At the same time, technological advancements and the use of laser have changed the face of endourology. Several new innovative treatments are now commonplace for benign prostate enlargement (BPE). Management of prostate cancer now involves procedures such as robotic prostatectomy, brachytherapy, radiotherapy, cryotherapy and HIFU. Robotic partial nephrectomy and cryotherapy have changed the face of renal cancer. En-bloc resection of bladder cancer is challenging the traditional management of non-muscle invasive bladder cancer and becoming commonplace, while robotic cystectomy is also gaining popularity for muscle invasive bladder cancer. Newer surgical intervention related to BPE includes laser (holmium, thulium and green light), water-based treatment (Rezum, Aquablation) and other ; minimally invasive procedures such as prostate artery embolisation (PAE) and Urolift. Endourological procedures have incorporated newer laser types and settings such as moses technology, disposable ureteroscopes (URS) and minimisation of percutaneous nephrolithotomy (PCNL) instruments. All these technological innovations and improvements have led to shorter hospital stay, reduced cost, potential reduction in complications and improvement in the quality of life (QoL).
