USING THE UNIVERSITY ENERGY EFFICIENCY KNOWLEDGE HUB FOR ENERGY CERTIFICATION AND ENERGY AUDITS OF HIGHER EDUCATION INSTITUTIONS

BACKGROUND AND OBJECTIVES. The general problem of the research is to define the essence of university energy efficiency as a special type of management of higher educational institution activity, increase of its energy autonomy level, scientific research on economical use of energy resources. University energy efficiency management is a special type of management, which is based on finding new opportunities to save energy resources based on innovations, ability to attract resources from a variety of sources.METHODS. Logic, system and statistical analysis, and multiple regression methods were used to conduct energy monitoring of HUB use of energy efficiency knowledge. The method of cluster analysis was used for energy audit and energy certification of university buildings. The average value, value of mode and median, indicators of variation (variation range, average linear deviation and variation coefficient) of daily electricity consumption of building No.4 of Kyiv National University of Technologies and Design were calculated, statistical analysis of obtained data was made.FINDINGS. Existing automatic energy accounting systems in university buildings were reviewed, a comparative table was compiled and the systems were ranked according to the sum of the scores obtained.The comparative analysis is carried out according to a set of criteria, including the unique features that distinguish these systems from each other. Based on the ranking results, the best model is selected and its advantages and disadvantages are identified. A simplified list of requirements and necessary functionality for the use of energy efficiency knowledge HUB for energy monitoring, energy audits and energy certification of university buildings has been developed.CONCLUSION. The obtained asymmetry coefficient made it possible to conclude that there is a right-hand asymmetry in the amount of energy used in the university. The selected main factors influencing energy consumption allowed to monitor the energy efficiency of the university in 2020. The use of multiple regression equation allowed to take into account the main factors of energy consumption, the extent of their influence, to compare the obtained results with the actual consumption, to build energy profiles and to carry out energy certification of all buildings of Kyiv National University of Technologies and Design.

ORGANIZATION OF THE ENERGY MANAGEMENT SYSTEM ON THE BASIS OF THE UNIVERSITY KNOWLEDGE HUB

BACKGROUND AND OBJECTIVES. Energy efficiency and energy saving are the priority direction of science, technology and engineering development in Ukraine. The policy of energy saving, carried out all over the world, is directed to all branches and scientific researches in all spheres. The big consumer of energy resources is the higher school. Updating of normative-legal and technical base aimed at design and operation of buildings with low energy consumption and high energy efficiency class shows the necessity of short-term solution of the problem. At the same time, there is a lack of a systemic view of energy efficiency, which does not allow evaluating the level of energy costs throughout the life cycle of higher education institutions, which shows the need to find effective solutions to the problem.METHODS. Multiple regression equation was used to assess the influence of factors on electricity consumption and energy efficiency of Kyiv National University of Technologies and Design, statistical analysis of the obtained data was performed.FINDINGS. As a result it was found out that the data of electricity consumption do not obey the law of normal distribution, so it is difficult to build an accurate prediction of electricity consumption. The use of HAB knowledge on energy efficiency allowed a more qualitative analysis and highlighted the main factors affecting electricity consumption. The university has unregulated central heating, individual air conditioning systems, and central and individual lighting. In this regard, we selected the following main factors: average outdoor air temperature, average duration of daylight hours, heating period, average number of people working per day, during the month to conduct energy monitoring and energy audit of university buildings.CONCLUSION. Implementation of suggested scheme of structural organization of typical system of automatic accounting of university energy consumption on the basis of university HUB of energy efficiency knowledge: server, allowing to collect, store and process data; routers by means of various wire and wireless communication technologies; hubs, installed on the objects of energy consumption; workstations, which are personal computers with installed software of used HUB will allow to optimize energy consumption.

USING THE ENERGY EFFICIENCY HUB IN THE UNIVERSITY ENERGY MANAGEMENT SYSTEM IN THE CONTEXT OF PREVENTING A NEW OUTBREAK OF THE COVID-19 PANDEMIC

BACKGROUND AND OBJECTIVES. The problem addressed by the project is the need to develop a new approach to energy saving and energy efficiency management in higher education institutions (HEI), whose main components are energy management, energy audit, energy certification, monitoring based on the reasonable use of international standards ISO 50001: 2011, which allows reducing or completely eliminating the barriers to energy efficiency measures related to lack of awareness of energy saving potential.METHODS. The international protocol of efficiency measurement and verification is proposed to be used as a basis for methodological support of energy efficiency analysis and control in the automated information system of energy efficiency analysis. The method of rationing of heat energy consumption, which takes into account the required level of statistical significance of energy resources saving when carrying out energy saving measures, was used to control the energy efficiency of HUB use of knowledge on energy efficiency. The methodological support of the subsystem of analysis of energy efficiency of heat energy resources consumption is considered.FINDINGS. A three-part system for improving the energy efficiency of a university based on the HUB of energy efficiency knowledge is proposed: an automated dispatch management system; an automated information system for energy efficiency analysis and a corporate management system for the heat and power complex.CONCLUSION. Compliance with the consumption rate calculated using the proposed method during the whole study period (second half of 2019 – beginning of 2021) allows to obtain a statistically significant value of thermal energy savings, which will significantly reduce the energy costs of the university in the COVID-19 pandemic crisis. An example of the use of the proposed energy efficiency knowledge HUB for building 4 of the Kyiv National University of Technologies and Design is presented.

ICT-SUPPORTED STUDENTS’ INDEPENDENT WORK IN THE ESP CONTEXT: THE NEW REALITY IN TERTIARY EDUCATION

The article aims at conducting empirical research of university students’ readiness to handle independent work while studying the English for Specific Purposes (ESP) course, subject to the availability of Information and Communication Technologies (ICTs). In order to accomplish the objective of the article, a mixed methods research was applied. According to the research methodology, the questionnaires were conducted during the first semester of the academic year 2019/20 and then in the first semester of the academic year 2020/21 at the Kyiv National University of Trade and Economics. The investigation covered the period before the outset of the pandemic when a blended learning approach included instructor-led classroom training and e-learning elements; and then during the time of the COVID-19 pandemic in Ukraine when webucation was in line with the priorities of the training process. The participants of the study were first-year and second-year students of non-linguistic specialities. The scientific research reflected that teaching ESP was focused on enhancing foreign language learning in the particular field of study such as IT, law, trade, marketing, management or economics, to equip students with the oral and written comprehension and speaking skills that they would need to leverage partnerships with international interlocutors in the business community. The obtained results confirmed the high value of the resources available online for studying ESP as an academic discipline in university-level curricula. The analysis of data showed that during the pandemic almost equal percentages of the respondents faced the challenges that accompanied the process of learning English online. Students noted all four proposed options that characterised the disadvantages of completing the assignments independently, namely the communication vacuum, difficulties in choosing supplemental instructional materials, as well as a lack of self-discipline and control. The outcome confirmed the need to assist students’ independent work. To meet that demand, the authors carried out a Strength, Weakness, Opportunity, and Threat (SWOT) Analysis related to the use of ICTs within the organising framework of students’ independent work while teaching ESP during a pandemic. It has been concluded that the opportunities and threats, as well as the strengths and weaknesses, identified through the SWOT analysis, characterise the advantages, drawbacks and peculiarities that emerge in the process of providing guidance for students’ independent work in the study of ESP, integrating them into a coherent whole.

Automation of the compliance matrix «Discipline – Competence» (by example of the educational masters program «Financial Intermediation»)

The object of this research is the automation of the compliance matrix «Disciplines – Competences», which are the links between the list of compulsory and elective disciplines of the educational program according to the curriculum and the set of competencies of the graduate required by the Standard of higher education. The development of the educational program includes a combination of disciplines with «Program Learning Outcomes», which is listed in the Standard. One of the most problematic places is time-consuming of the process of «drawing-up» the links from «General Competencies» (GC) and «Professional Competencies» (PC) of disciplines to «Program Learning Outcomes» (PO). This problem is considered on the basis of the Educational and Professional Program (OPP) «Financial Intermediation» Academic Degree «Master» specialty 072 «Finance, Banking and Insurance» in the field of science 07 «Management and Administration» of the Department of Banking of Kyiv National University of Trade and Economics (KNUTE, Ukraine). The research methods are to use the design of relationships between logical elements («entities») of the data model (Entity-Relationship Model). To develop a compliance matrix «Disciplines – Competences» in the paper the author proposed a software application based on Excel (hereinafter «Application»), which allows to automate the construction of such links. There is a significant reduction in the time-consuming of preparing educational programs by guarantors and support groups. This is due to the fact that the proposed application has a number of features of use, in particular automates the construction of matrices of correspondence «Discipline – Competence». The method of automation of the compliance matrix «Disciplines – Competences» proposed in the research was successfully tested by the author in the development of educational and professional programs of KNUTE, namely «Financial Intermediation», «Management of Banking Business» and «Financial Brokerage». Thus, the application is universal and can be used by guarantors and support groups to build Compliance Matrices of the educational programs of other specializations and specialties.

LIBRARY ONLINE SERVICES DURING COVID-19: THE EXPERIENCE OF LIBRARIES IN CROATIA AND UKRAINE

The purpose of the article is to identify activities in providing online services during forced quarantine on the example of public libraries’ activities in Croatia and university libraries in Ukraine. The study aimed to identify, analyse, and characterise online services offered by libraries to establish remote customer service during the forced quarantine. The results of the study are presented in three sections. The first analyses the work of Croatian public libraries; the second, presents the experience of Ukrainian libraries; in the third, there is the case of the Scientific Library of Kyiv National University of Culture and Arts is displayed. The scientific novelty of the article is to identify practices for providing online services by libraries in Croatia and Ukraine during the COVID‑19 pandemic. The study shows that Croatian public librarians, as well as Ukrainian librarians, have demonstrated they can quickly adapt and use digital technologies on behalf of their supporters. Libraries went from developing imaginative practices to create online spaces in a matter of weeks. The result was a massive amount of produced content like workshops for children and adults; streamings of online events, organisation of virtual exhibitions, and collecting verified reference sources for research and learning. Another one of the impacts of this crisis was the accelerated development of digital library services, including online membership registration and the acquisition of e-books by public libraries. Public response was more significant than ever, including following, commenting, and sharing digital content created or shared by public libraries. The study found that the challenges of the COVID‑19 pandemic have intensified the digitisation of Ukrainian libraries and led to changes in activities. University libraries quickly adapted to remote work, offering their users a variety of remote services. The authors hope that the considered practices will contribute to disseminating better experience of libraries during quarantine in general and online services in remote maintenance in particular.

Information Literacy Programmes: the Experience of Research Libraries in Hong Kong and Ukraine

The article is devoted to the analysis of information literacy programmes developed by libraries of higher education institutions in Hong Kong and Ukraine. The application of such theoretical and empirical methods as an analysis of sources, the method of external observation over the foreign and Ukrainian experience of the information literacy programmes developing, as well as a prognostic method for summarising, allowed to reveal similarities and differences in the content and forms of information literacy programmes implemented at Hong Kong and Ukrainian universities. Different stages of implementation of information literacy programmes by the Chinese University of Hong Kong (CUHK) Library during the last two decades are highlighted. The content of information literacy programmes provided by the libraries of 4 Ukrainian universities in general and the scientific library of the Kyiv National University of Culture and Arts (KNUCaA), in particular, is reviewed. It has been found out such similar characteristics of information literacy programmes of libraries that were analysed as using of traditional forms (lectures, practical exercises, instructions, video lessons) to form the skills and abilities for the effective information search, analytical processing, organisation, evaluation, and use of this information. It has been found out that, unlike Hong Kong, the introduction of certified and online information literacy courses by Ukrainian universities libraries is isolated cases. There is also no experience in testing students’ knowledge before studies of information literacy. Testing is usually done after completing the information literacy programmes, but these tests are not mandatory and only recommended. The authors hope that the experience of the CUHK Library (Hong Kong) in the implementation of the “Immersion Programme”, the UGCIL project, and InfoLit for U will be useful for the Ukrainian scientific library community, considering that libraries of higher education institutions in Ukraine have also started to develop similar programmes and modules. In particular, the interactive online guide “Music Documents in the KNUCaA Scientific Library” is an example of a modern approach to the formation of first-year students’ information literacy, their acquaintance with the scientific library, its services, and resources, basic types of documents, an electronic search algorithm.

The Staple-Shape Plate Springs Engineering Calculation Method

The new types of elastic devices – staple-shape plate spring and leaf spring - have been developed at the Kyiv National University of Construction and Architecture. The staple-shape plate spring is an elastic plate where the ends are deflected from its middle part in the same direction and are made in the form of consoles equipped with hinge attachments. The middle part of the plate as a parallel to the line of the load action is designed with variable length section. In each section, the axis, relative to which the moment of the section inertia is a maximum, is perpendicular to the spring bending plane, designed as the equal resistance beam. This article substantiates the feasibility of using a staple-shape plate spring to improve the elastic suspension of truck cabs. The recommendations for choosing the most promising mass production directions, as well as the engineering calculation methods of such springs, have been developed. Objects of the study are devices intended for machines and their components dynamic loads shock absorption, differing in having a bracket shape and being a subject to bending in the plane of the highest rigidity of their cross sections, as well as shock absorbers using these springs, in particular KamAZ cabs suspension. This research implementation allows significantly reducing the metal consumption and elastic devices manufacture complexity, as well as can be useful in the design and operation of elastic car suspensions.Keywords: elastic device, staple-shaped plate spring, leaf spring, elastic suspension

Experience in teaching analytical chemistry in a joint English-language educational project of Chinese and Ukrainian universities

The paper was aimed to study the problems that may arise when Chinese students learn an analytical chemistry course in English, read by teachers from Ukraine. In particular, the reasons for the possible excessive increase in cognitive load were investigated. The comparative analysis of the existing learning styles was carried out to achieve the goal of the study. For this purpose, the indicators were compared for respondents studying in similar chemical specialities at the Kyiv College of the Qilu University of Technology in China and Kyiv National University of Technologies and Design in Ukraine. Some students from China demonstrate more pronounced reflective, verbal and intuitive learning styles. In contrast, a decisive advantage towards active, visual and sensing styles is characteristic of Ukraine students. The structure of the lecture course was analysed from the viewpoint of e-resources used. The optimal application of different electronic resources for students with varying learning preferences was established based on the results of experiments by the method of dual-task. The difference in educational priorities should be reflected in the various forms and methods used in the teaching of chemical disciplines. Recommendations for the development of appropriate learning resources are given.

Integrated evaluation of investment attractiveness in the context of economic sectors: Ukraine as a case study

This study explores the evaluation of investment attractiveness of Ukraine’s economy. The following factors are analyzed: the social significance of the sector, the coefficient of support for the sectoral development, the coefficient of production efficiency, the index of fierce competition, and the inflation index. The results of applying the calculation of the average value of the weighting factor within a particular sector and the method of the sum of sets show that the most significant influence on the investment attractiveness of the economy sector are factors of economic efficiency and support of the sector by the state. The study is based on the development and calculation of an integrated indicator of sectoral attractiveness. This approach makes it possible to take into account a set of factors and more accurately describe the existing priorities of a particular sector of the economy. The conclusion is that that the most attractive sectors in Ukraine are industry, trade, transport and communications, as well as financial activities. The education sector remains the least attractive for investment. It is estimated that its attractiveness does not exceed 10% of the threshold. Unattractive for investments sectors will need special attention from the government. Correcting the current situation and attracting additional investment in such areas can significantly reduce the burden on the state budget. The findings of this investigation can be used in order to expand the existing tools for the formation of economic policy of Ukraine and improve the practice of evaluation of sectoral investment.

Study of peculiarities of social network using depending on personal psychological well-being

The study of psychological well-being is a really important issue of the modern society and the contemporary science. Many mental disorders and psychosomatic diseases are anteceded by mood decline, experience of ill-being. If the sense of satisfaction is absent, tensions, inconsistency in actions appear and overall functional efficiency decreases. The life style of very many people has undergone dramatic changes over the last 20 years. One of the main reasons for these changes is emergence of the Internet and its special faculty – social networks. It is well known that communications are a necessary structural component of psychological well-being. Emergence of social networks has expanded communicative opportunities to virtual infinity; at the same time, such communications swallow up personal time and efforts. This article makes an attempt to analyze peculiarities of personal behavior in social networks depending on a personal level of psychological well-being. Students of the Kyiv National University (Kyiv, Ukraine) and working youth have been examined with Ryff’s Scales of Psychological Well-Being and our structured interview. The obtained results show differences in attitudes and behavioral patterns in social networks depending on a person’s level of psychological well-being.
