The Role of University in Heritage Research and Practice: Siberian Context

The risk of losing identity and historical values seems indispensable as attributes of the explosive growth of modern cities. However, along with the disappearance of each piece of heritage, citizens tend to lose memories and "identical" feelings, which make the place special and unique. The role of universities and architects in the heritage process of the modern city can be more significant: there are many successful examples around the world, which clearly demonstrate that the group of researchers from the Siberian Federal University made an attempt to compensate both for the lack of connection between the university and the city, and the lack of comprehensive approaches to the heritage process in Krasnoyarsk, Siberia. For the experimental design research, the part of the Military camp, the degrading place with a bright history in Krasnoyarsk, was selected. Thorough research and examination are required to extract the values of the place. For the experiment, students conducted a deep analysis of historical facts, values, narratives, habits, and beliefs before developing their project proposals. The paper questions the role of the university and architects in the heritage process of modern Siberian city, experimenting with the particular precedent in Krasnoyarsk and suggests the methods of participation in sustaining identity and providing continuity in historical environments

Reading urban form as a studio teaching method: case study in Siberia

Quite often heritage monument is perceived as a separate domain in Russian conservation theory and practice. Teaching practice demonstrates the situation clearly: quite commonly studio regeneration projects are conducted in isolation from the context, or lacking the methodology for preliminary analysis. However, many international concepts attempt to avoid isolation of buildings as physical objects from a cultural environment with its multi-layered history of significances (Waterton & Watson, 2015). The paper presents a case study of the application of urban morphology as a research tool and a teaching method (Caniggia & Maffei, 2001), to the Siberian context. Research group of Siberian Federal University (SFU) organized the experiment, in which students worked on the two stages of a regeneration project for the old Military camp in Krasnoyarsk. Between the two stages, the workshop was organized for students of Sapienza University and SFU to conduct a methodological study. Then the research group continued the second stage of the experiment in which examined the applicability of morphological analysis in Siberia. The qualitative difference of regeneration proposals before and after the application of morphological analysis, as well as the level of subsequent students’ proficiency, proved the potential applicability of the method in Siberian academy and practice, and effectiveness of the workshop as the tool for its introduction

Іmprovement of the methodical approach to the analysis of the efficiency of management of the material and technical base of the hotel establishment

Rational management and constant updating of the material and technical base are important tasks for any business entity in the hotel sector. The subject of research in the article is the management of the material and technical base of the hotel industry. The purpose of the article is to generalize the theoretical and methodological approaches to the essence, composition and analysis of the effectiveness of management of the material and technical base of a hotel and to substantiate on this basis an improved methodological approach to the assessment of the effectiveness of its management. Research methods: analysis, synthesis, generalization, systematization, comparison, induction, deduction, abstract-logical method, graphical and tabular methods (for a visual representation of the analyzed material). The following results were obtained: the main approaches to the essence of the concepts "material and technical base of the hotel industry" were analyzed and their differences were established. Scientific approaches to the structuring of the material and technical base of the hotel are considered. The requirements for the material and technical base for various categories of hotel establishments according to DSTU 4269:2003 were  analyzed. Differences in the requirements for the material and technical base for various categories of hotel establishments according to the Standard "EEIG EU for hotels" have been determined. The main problems of the modern state of the material and technical base of the hotel industry in Ukraine were summarized. An analysis of the scientific literature on the available methodical approaches to the analysis of the effectiveness of the management of the material and technical base of the hotel was carried out. It showed the lack of an established methodology for researching the effectiveness of formation and use in the effectiveness of hotel management, the focus of scientists on the diagnosis of certain aspects of the management of the material and technical base: the analysis of strategic aspects of management, the analysis of indicators of the use of fixed assets or current assets, the evaluation of the hotel's operational program, etc. Conclusions:  the conducted research made it possible to substantiate the author's method of managing the material and technical base of the hotel establishment, which includes nine stages, and allows for a comprehensive analysis of the effectiveness of  the management of the material and technical base of the hotel establishment from the standpoint of compliance with the requirements of the regulatory framework, the rationality of the management organization, evaluation indicators of the effectiveness of formation and use, analysis of losses of the establishment due to downtime, assessment of guest satisfaction with the material and technical base, which will allow identifying existing shortcomings, link strategic and current management tasks, develop appropriate management solutions to eliminate the identified problems and carry out their economic evaluation

Solid-phase spectrophotometric iodometric determination of nitrite and selenium(IV) using a polymethacrylate matrix

Procedures for the iodometric solid-phase spectrophotometric determination of nitrite and selenium( IV) using a polymethacrylate matrix are proposed. The procedures are based on the reaction of nitrite and selenium(IV) with iodine in an acidic medium with the release of free iodine in amounts equivalent to those of the substances to be determined, extraction of the iodine formed with a polymethacrylate matrix, and measurement of absorbance of the matrix at 370 nm. The developed procedures ensure the determination of 0.01–0.12 mg/L of nitrite and 0.05–0.40 mg/L of selenium(IV) with limits of detection of 0.005 and 0.03 mg/L, respectively. It was shown that the proposed procedures can be applied to the determination of selenium(IV) in mineral water and nitrites in vegetables and soil

Augmented reality for minimally invasive spinal surgery

BackgroundAugmented reality (AR) is an emerging technology that can overlay computer graphics onto the real world and enhance visual feedback from information systems. Within the past several decades, innovations related to AR have been integrated into our daily lives; however, its application in medicine, specifically in minimally invasive spine surgery (MISS), may be most important to understand. AR navigation provides auditory and haptic feedback, which can further enhance surgeons’ capabilities and improve safety.PurposeThe purpose of this article is to address previous and current applications of AR, AR in MISS, limitations of today's technology, and future areas of innovation.MethodsA literature review related to applications of AR technology in previous and current generations was conducted.ResultsAR systems have been implemented for treatments related to spinal surgeries in recent years, and AR may be an alternative to current approaches such as traditional navigation, robotically assisted navigation, fluoroscopic guidance, and free hand. As AR is capable of projecting patient anatomy directly on the surgical field, it can eliminate concern for surgeon attention shift from the surgical field to navigated remote screens, line-of-sight interruption, and cumulative radiation exposure as the demand for MISS increases.ConclusionAR is a novel technology that can improve spinal surgery, and limitations will likely have a great impact on future technology

Apport De La Stratigraphie Sequentielle Dans L’evolution Jurassique Du Moyen Atlas Central (Maroc)

The Jurassic evolution of the central Middle Atlas is governed by various factors (climate and eustatism). The use of the concepts of sequential stratigraphy in the regions of Tagnamas and Boulemane allowed to interpret the geometry and the vertical sequence of sedimentary sets. Twelve sequences are identified and delimited by sedimentary discontinuities. The lithostratigraphic division adopted in this study is synchronous with the coastal aggradation charter of Haq & al. (1987 & 1988) and Rioult & al. (1991). The correlations on a regional scale, between different Jurassic lithostratigraphic units is possible, whose the major factors controlling the evolution of intraplate basins are climate and eustatism
