Development of a Methodology for Assessing the Technical Level of Cultural Heritage Objects in Construction

Cultural objects (building and construction) that are considered as the most valuable segment of real estate in terms of historical heritage usually evaluated only by monetary aspects. Not concreteness of the approaches to the determination of the historical heritage objects leads to the fact that its original value often remains unread, the assessment has subjective character, reflects the values of certain time frame and place. Therefore, for the purpose of determination of value of the historical heritage objects, there is need for the creation of the unified classification system of their assessment. Thus, this research is considered to be very relevant. The paper investigates intangible factors that affect the evaluation of cultural heritage objects in construction. In the work a system of value indicators, which take into account not only tangible indicators but also the intangible value of cultural heritage objects, has been developed. Developed indicators system makes it possible to evaluate the historical and cultural value of real estate objects quite objectively on the contrary to common methods which deal only with monetary aspects of market price of such objects. A methodology for a comprehensive evaluation of cultural heritage objects has been formed as well. This methodology is based on both the traditional comparative approach and the system of value indicators. As a result, suggested integrated approach has been proven to provide fair evaluation of both the tangible and intangible characteristics and improve the quality of cultural heritage objects assessment process. Doi: 10.28991/cej-2021-03091680 Full Text: PD

Optimization of the Concrete Composition Mix at the Design Stage

The problem of the composition optimization of concrete mixes seems to be quite urgent as errors at the composition design stage can lead to problems of concrete at the stage of exploitation such as delamination, cracking etc. Reasonable selection of concrete mix components guarantees the required strength of concrete and reinforced concrete structures in the future. This paper investigates the influence of the concrete mix composition on the strength of concrete. Firstly, typical risks that can occur on the composition design stage have been identified through the experts' interviews. Secondly, this risks were associated with indicators and characteristics that can be tested experimentally. Running of several mathematical models has allowed to outline concrete mix parameters of highest importance and formulate an empirical equation for the dependence of the strength of the concrete mixture on the values of the coarse aggregate quality factor, the fine aggregate fraction and the consumption of the Portland cement has been proposed. As a result, a methodology for controlling the quality of concrete at the stage of the composition design has been formulated. Doi: 10.28991/cej-2021-03091732 Full Text: PD

Development of methodology for evaluation of innovative IT-projects

Innovative business development based on a digital transformation is the urgent task for companies. It is able to ensure the implementation of innovation strategy and digital transformation of business. Due to the high development speed and the IT-market updating, the problem is lack of methods of rational choice of the IT-project. In practice, companies often implement IT-projects without reasonable selection and ranking, which leads to a high proportion of failed innovative IT-projects. As a result, the company does not receive a commercially successful product or service that stands out to the consumer among competitors. The evaluation of innovative IT-projects is based on the financial indicators analysis of the expected results from the implementation. The evaluation of the strategic coherence of the project is ignored. The research approaches the methodical of ranking innovative IT-projects in companies. The method consists in a comprehensive analysis of the impact of the proposed project results in various aspects of the company (strategic, environmental, organizational and technological). The study highlights the features of innovative projects in the field of information technology, a comparative analysis of methodological approaches to the evaluation of innovative projects, modified the model of acceptance of IT-innovations

Development of methodologies of innovation management for digital agricultural enterprises

Digital transformation is gaining its momentum in all industries. On the one hand, agriculture is usually considered as an outsider industry in terms of digitalization. On the other hand, during the last decade several countries have managed to improve the quality of agricultural industry and solve many of its problems with the use of modern information and digital technologies. In Russian Federation the Ministry of Agriculture announced the national project “Digital agriculture”, however the Projects is hard to release due to the lack of employees with decent soft and digital skills which are essential to the process of digital transformation. There are several models and frameworks of digital competences management, but none of them considers the specifics of agricultural sector. Thus, authors in this pre-research article justify the necessity to develop adaptable methodology for innovation management via various types competencies (hard, soft, digital ones) based on preliminary investigation of problem and solutions used in other countries
