Authors: Solovyova E. V. , Berdnikova V. N.
Published: June 2022

Relevance. Housing costs rose significantly in the housing market during the pandemic. Тhere was a great interest in the price from state regulatory authorities and market participants. Domestic and foreign researchers mainly identify price bubbles. They compare the income of the population, the price of rent and the cost of housing and do not pay attention to calculating the scale of speculative price bubbles. Today in Russia, the study of this problem is relevant.

The purpose of the study was to develop a methodology for identifying speculative price bubbles on the real estate market. It uses the value of the fair value during the period of stability, the simulated fair value and the market value in the conditions of a hype market.

The objectives of the study were to provide a dynamic analysis of the housing market, identify periods of stability of excessive price growth in the market, simulate fair value with stable values of price-forming factors and calculate the size of the price bubble.

Methodology. The research is based on correlation and regression analysis, an index method of information processing.

Results. The percentage sizes of speculative price bubbles were established. The fair price base in the housing market was adopted, a scale for dividing speculative bubbles was developed.

Conclusion. Calculations were made for the housing market in Sochi in 2021, a euphoric price bubble of 54 per cent was calculated. Macroeconomic factors have not changed, so the market price requires special attention from interested parties.

Authors: Kobleva Z. Kh.
Published: June 2022

The relevance of the research topic is caused by the emergence of serious scientific interest in the study of value orientations in the system of succession of generations at the present stage. The article is devoted to topical issues of generational continuity and the specifics of the formation of intergenerational ties, in order to identify the features of the value attitudes of modern youth, manifested in ways of behavior that are not characteristic of the Russian mentality in relation to the older generation.

The purpose of this article is the need to identify and study the features of the formation of value orientations in the process of intergenerational relations in modern society.

Objectives: to study the values of modern society in the system of generational succession; to identify the features of the relationship between the younger and older generations; to show the transformation of the system of intergenerational ties in modern conditions that form the basis of the process of generational succession of society.

Methodology. In the process of writing the article, methods of systemic, structural and functional analysis were used, methods of comparison, observation, and questioning were used in the process of studying value orientations in the system of generational succession.

Results. The practical significance of the article lies in the use of provisions and conclusions in the creation of family information policy of the state, aimed at strengthening ties between generations. A sociological study conducted within the framework of the problem under study made it possible to determine the attitude of young people to the older generation, analyze the features of value preferences and attitudes among young people in the system of generational succession, which revealed the need for dialogue between generations as an opportunity to ensure harmonious interaction at the intergenerational level.

Conclusions. The transformational processes affecting the institution of the family, caused by modern trends in the socio-economic and political spheres, reflected in the emergence of new value attitudes among the younger generation, which are based on the dominance of individual values, without taking into account the unique, socio-cultural experience of the older generation, had a significant impact on the state of the system of traditional succession of generations. In these conditions, it is necessary to re-establish contacts that promote the establishment of traditional ties between generations, in which they will be interested in order to continue the historical and socio-cultural continuity of generations.

Authors: Voronin I. A.
Published: June 2022

Relevance. Money laundering has strong consequences throughout the world, which distort and seriously distort economic processes, since it can completely destroy the political and financial systems of a country. Credit organizations, as intermediaries in financial transactions, are the main participants in the process of legalization of income and anti-money laundering activities. Therefore, risk management becomes a decisive element for identifying actions that may indicate suspiciousness of a transaction, and associate its participants with money laundering, and requires banks to form special methodological tools.

The purpose. In this article, it is planned to consider issues related to the study of methodological approaches to assessing client risks used in world practice, when assessing banks in anti-money laundering activities and the possibility of their adaptation in the activities of Russian credit institutions.

Objectives. Within the framework of the scientific article, scientific tasks were set and solved to develop a methodological approach to assessing client risks (including a new client and a client with a long service period) of involvement in legalization of income.

Methodology. The proposed methodological approach is implemented using linear regression and gradient boosting methodology based on a decision tree.

Results. The research carried out allows us to form two models that offer solutions for identifying new and old clients whose activities involve money laundering.

Conclusions. Considering that the supervisory authorities are increasingly focusing on developing the ability of banks to prevent suspicious transactions in advance, this requires a credit institution to develop a set of various tools that allow a high level of probability to identify suspicious transactions by a client and prevent them from being carried out in the bank.

In an age when publicity is the norm, human loneliness is a significant socio-psychological problem. Objective loneliness (e.g., as experienced during the pandemic) does not always result in subjective loneliness. Subjective loneliness directly influences various aspects of the human psyche and activities. Analysis of satisfaction with social life, as a marker of social well-being and academic adaptation of students with different loneliness types, allows determining the magnitude of subjective loneliness and how it influences the well-being and adaptation of students. In this study, we analyzed satisfaction in social life, difficulties associated with distance learning, and academic adaptation in students with different types of loneliness. The sample consisted of 500 students who studied online during the COVID-19 pandemic. The mean age of the students was 19.28 years (SD = 2.16; 16.5% males and 83.5% females). The following methods were used in this study: A differential questionnaire on experiencing loneliness developed by Osin and Leontev; a modified technique for determining the level of social frustration by Wasserman, Iovlev, and Berebin; the academic adaptation scale by Shamionov, Grigoryeva, Grinina, and Sozonnik; scales for subjective evaluation of changes in life during distance learning developed by the authors of the study. Four types of loneliness were identified based on cluster analysis: positive loneliness, non-accepted loneliness, pseudo-positive loneliness, and neurotic loneliness. Students with pseudo-positive and neurotic loneliness had low levels of satisfaction with their social life, while students with positive loneliness, and those that rejected it, were satisfied with life. Distance learning was most positively viewed by students with a positive perception of loneliness, while students with neurotic loneliness experienced difficulties the most because of distance learning. Under such conditions, the most successful academic adaptation was observed in students with non-acceptance of loneliness, followed by students with positive and pseudo-positive loneliness, respectively, while students with neurotic loneliness adapted the least to the conditions.

Authors: Bergeron Lysa , Décary Simon , Djade Codjo Djignefa , Daniel Sam J , Tremblay Martin , Rivest Louis-Paul , Légaré France
Published: June 2022

BACKGROUND

Web-based continuing professional development (CPD) is a convenient and low-cost way for physicians to update their knowledge. However, little is known about the factors that influence their intention to put this new knowledge into practice.

OBJECTIVE

We aimed to identify sociocognitive factors associated with physicians’ intention to adopt new behaviors as well as indications of Bloom’s learning levels following their participation in 5 web-based CPD courses.

METHODS

We performed a cross-sectional study of specialist physicians who had completed 1 of 5 web-based CPD courses offered by the Federation of Medical Specialists of Quebec. The participants then completed CPD-Reaction, a questionnaire based on Godin’s integrated model for health professional behavior change and with evidence of validity that measures behavioral intention (dependent variable) and psychosocial factors influencing intention (n=4). We also assessed variables related to sociodemographics (n=5), course content (n=9), and course format (eg, graphic features and duration) (n=8). Content variables were derived from CanMEDS competencies, Bloom’s learning levels, and Godin’s integrated model. We conducted ANOVA single-factor analysis, calculated the intraclass correlation coefficient (ICC), and performed bivariate and multivariate analyses.

RESULTS

A total of 400 physicians participated in the courses (range: 38-135 physicians per course). Average age was 50 (SD 12) years; 56% (n=223) were female, and 44% (n=177) were male. Among the 259 who completed CPD-Reaction, behavioral intention scores ranged from 5.37 (SD 1.17) to 6.60 (SD 0.88) out of 7 and differed significantly from one course to another (P<.001). The ICC indicated that 17% of the total variation in the outcome of interest, the behavioral intention of physicians, could be explained at the level of the CPD course (ICC=0.17). In bivariate analyses, social influences (P<.001), beliefs about capabilities (P<.001), moral norm (P<.001), beliefs about consequences (P<.001), and psychomotor learning (P=.04) were significantly correlated with physicians’ intention to adopt new behaviors. Multivariate analysis showed the same factors, except for social influences and psychomotor learning, as significantly correlated with intention.

CONCLUSIONS

We observed average to high behavioral intention scores after all 5 web-based courses, with some variations by course taken. Factors affecting physicians’ intention were beliefs about their capabilities and about the consequences of adopting new clinical behaviors, as well as doubts about whether the new behavior aligned with their moral values. Our results will inform design of future web-based CPD courses to ensure they contribute to clinical behavior change.
Mental Health Apps for Children - Support or Downside? A Scoping Review. (Preprint)
Authors: Käferböck Anna-Sophie
Published: June 2022

BACKGROUND

Mental disorders in children are diagnosed either late or not at all. As a consequence, there remain fewer treatment options for this age group than for adults. Smartphone applications with specialization on this issue promise first achievements to provide possible support options.

OBJECTIVE

The aim of this scoping review is to provide evidence-based information regarding the support of digital apps designed for children with psychological distress and their emotional well-being.

METHODS

This study screened six online databases for evidence of mental health apps for children under 18 years of age with anxiety disorders, depression, eating disorders or insomnia. Six articles were included and critically appraised using critical appraisal tools. The discussion of the included publications and comparison of them with each other constituted the final part of the review.

RESULTS

Five supportive smartphone mental health applications adapted to the needs of children and adolescents were identified. These apps were evaluated and first improvements in the management of mental illness in those under 18 years of age were shown. Standalone approaches without need for previous therapy as well as versions that can be used in combination with interventions prove to be equally effective.

CONCLUSIONS

Early results indicate an existing potential of these applications in enhancing the mental well-being of affected adolescents and children. In order to consolidate the results found and to make such possibilities available to the broad masses, well-founded research with numerous study participants is necessary in the future.
The Impact Of Thin Trading Adjustments On Exchange Rate Exposure
Authors: Lily Jaratin , Bujang Imbarine , Karia Abdul Aziz
Published: June 2022

This study investigates the multiple exchange rate exposure of large non-financial firms in Asia and emerging countries using the unadjusted and adjusted two-factor exchange rate exposure model. The autoregressive-distributed lag (ARDL) method was applied to investigate the existence of exchange rate exposure. The Dimson-Fowler-Rorke (DFR) adjustment method was applied to adjust the ordinary least squares (OLS) market risk estimator for the thin trading phenomenon. The study’s findings indicate that exchange rate exposure does affect firm value. Incorporating the DFR market beta in the exchange rate exposure model indicates two important findings. Firstly, there is a significant increase in the number of firms exposed to exchange rate movements, especially in Indonesia, Thailand, Sri Lanka, and Vietnam. Secondly, there are more firms that will be exposed to multi bilateral exchange rate exposure across the sample countries. The findings imply that market characteristics such as thin trading could be an alternative explanation of the exchange rate exposure puzzle. Furthermore, future research should include asymmetric analysis as an alternative explanation for exchange rate exposure.

Published: June 2022

Entrepreneurship continues to grow and receives a great deal of interest from business researchers and practitioners for its importance in the modern economy. This study aims to contribute to the body of knowledge that the entrepreneurial ecosystem correlates with founders' perceptions and startup success. Data were gathered from surveys of 200 founders or CEOs of SMEs and startups in Tay Ninh City (Vietnam), who have operated their own companies for at least five years. The primary data analysis was performed using the partial least squares (PLS) technique. Five out of six ecosystem factors significantly affect entrepreneurs' perceptions and startups’ success, based on the results of the empirical data. Besides, the founders' perceptions also positively affect the success of a startup. The implications show the need to enhance entrepreneurship in a nation.

Authors: Malik Abdul , Sideng Uca , Jaelani Jaelani
Published: June 2022

One of the essential services provided by mangroves is carbon sequestration, and therefore climate change mitigation. While previous assessments of mangrove carbon stocks and sequestrations have focused on the estuarine and deltaic mangrove setting, there are still limited studies carried out at small island mangroves. The study aims to assess mangrove biomass carbon stocks in Pannikiang, a small island in South Sulawesi, Indonesia, which occupies 91.64 ha of species-rich pristine mangrove forests. A field-based data collection survey was performed using a circular plot approach, while above-ground tree carbon (AGC) and below-ground root carbon (BGC) stocks were estimated using available species-specific allometric equations. The mean AGC and BGC were 5.34 ± 0.17 and 1.68 ± 0.04 Mg C ha-1, respectively. Bruguiera gymnorrhiza mangrove species stored the greatest of carbon stocks, followed by Scyphiphora hydrophyllacea. Carbon stocks obtained from small island mangroves in this study were lower than stocks assessed from other mangrove locations across Indonesia and Southeast Asia. However, historical rates of deforestation in Pannikiang Island may generate emissions to approximately 82.17 Mg CO2-eq. Findings from this study will be beneficial in providing baseline data for policy decision-making on climate change mitigation in the region, specifically for improved land use management via a low carbon development agenda.

An Exploratory Data Analysis for Synchronous Online Learning Based on AFEA Digital Images
Authors: Syefrida Yulina  , Mona Elviyenti
Published: June 2022

The spread of COVID-19 throughout the world has affected the education sector. In some higher education institution, such as Polytechnic Caltex Riau (PCR), it is mandatory for students to participate in synchronous or asynchronous learning activities via virtual classroom. Synchronous online learning is usually supported by video conferencing media such as Google Meeting or Zoom Meeting. The communication between lecturers and students is captured as an image as evidence of students’ interaction and participation in certain learning subjects. These images can provide information for lecturers in determining students’ internal feelings and measuring students’ interest through facial emotions. Taking this reason into account, the current research aims to analyze the emotions detected in facial expression through images using automatic facial expression analysis (AFEA) and exploratory data analysis (EDA), then visualize the data to determine the possible solution to improve the educational process’ sustainability. The AFEA steps applied were face acquisition to detect facial parts in an image, facial data extraction and representation to process feature extraction on the face, and facial expression recognition to classify faces into emotional expressions. Thus, this paper presents the results obtained from applying machine learning algorithms to classify facial expressions into happy and unhappy emotions with mean values of 5.58 and 2.70, respectively. The data were taken from the second semester of 2020/2021 academic year with 1,206 images. The result highlighted the fact that students showed the facial emotion based on the lecture types, hours, departments, and classes. It indicates that there are, in fact, several factors contributing to the variances of students’ facial emotions classified in synchronous online learning.

Published: June 2022

This research investigates the violations of Gricean maxims committed by the main characters in the TV series You Season 1, especially Joe Goldberg and Guinevere Beck. It focuses on how the two characters violate the maxims and the possible purposes behind each violation. Quantitative and qualitative methods were applied to the data analysis. The results show that 100 maxim violations were found in the first season of the series. The most frequently occurring violation is the violation of the quality maxim with 56 occurrences (56%), followed by the relation maxim (28%) and the manner maxim with (10%). The least occurring violation is the violation of the quantity maxim (6%). Joe Goldberg and Guinevere Beck tend to violate the maxims by being dishonest, saying irrelevant things, giving vague or obscure responses, and providing insufficient or unnecessary information. Several purposes of violations can be identified throughout the data, namely to avoid unwanted responses, avoid suspicion, make certain impressions, deceive, divert, persuade others, and relieve worries.

Authors:   Moscow State University of Civil Engineering (National Research University) (MGSU), Sborshchikov Sergej B. , Zhuravlev Pavel A.
Published: June 2022

Introduction. Scientific and technological progress, changes in consumer demand and production capabilities of the construction industry, nature and climate change, sanitary, environmental and geological changes make implemented area development (planning) solutions obsolete. Renewal, qualitative reconstruction and transformation of territories resolve contradictions between consumer needs and characteristics of urban planning solutions. The reengineering of areas (sites) is an effective response to the community demand for a comfortable and safe environment (territory) for living activities. Processes of transformation and reorganization of territories encompass various reengineering methods. Materials and methods. The subject of this research is the reengineering of areas. The authors present its organizational pattern, encompassing renovation and reclamation. They have identified and described the reengineering events, that may result in a number of land site transformations. The criteria that characterize the organization of actions towards the reengineering of areas are described. Research methods include structural and functional analysis. Results. The authors have found that the reengineering of areas deals with the choice of a management pattern (for exa­mple, a general contractor agreement, an engineering services provision agreement, or a consolidated solution). It is observed that the action/workflow management methods and patterns determine the breakdown of participants by the stages and types of reengineering works. An assessment of business and production processes is provided subject to the management patterns applied to the reengineering of areas. Conclusions. A limited choice of organizational patterns is applicable to the reengineering of areas due to the limited choice of activities. It is emphasized that the number of organizational patterns designated for the reengineering of built-up areas will be larger due to their modifications associated with a particular set of participants acting within the framework of event/workflow management methods (a general contractor or an engineering services provider). The conclusion is that in the future organizational patterns, applicable to reengineering, will determine the distribution of functions and provision of resources.

Introduction. The article addresses one of the most important student problems: accidents and injuries both during the period of study at higher education institutions and in the course of the work in student construction teams (SCB). A comparison was made between the social guarantees provided to students and the military personnel. The authors have found that there is no reliable statistical data on accidents and traumatism among students. The correlation between student attendance, successful learning, accident and traumatism prevention was analyzed. Causes of accidents in the course of construction activities are provided. The purpose of the article is to arouse a dispute, which may lead to the comprehensive solution to the problem of the social security of students during the period of their study at higher education institutions and work in student construction teams. Materials and methods. This problem was addressed from the standpoint of the social security of students and the safety of their personal data. The general statistics of accidents and injuries among young people during their study and work in student construction teams is provided. Continuous and sampling research methods were used to select statistical data in the process of solving this problem. Results. The article addresses the problem of investigation, registration and accounting of accidents that happened to students during their stay in organizations carrying out educational activities and in student construction teams. The authors suggest an empirical formula that has an additional coefficient for assessing the student performance. The formula takes account of the student attendance score and allows to make recommendations for improving preventive activities in the field of occupational safety of employment with student construction teams. Conclusions. The authors identified the problem of implementing prevention programmes focused on the reduction of morbidity and injuries among students. This problem deals with poor communications between the university schools, leaders of student construction teams, and occupational safety departments. The authors make recommendations on enhancing occupational safety activities are made.

Published: June 2022

Introduction. Presently, the evaluation of underground railways in regional cities of Russia enjoys little attention in the research literature. We have assessed the relationship between passenger flows of underground railways in regional Russian cities and the number of residents within walking distance of the stations. This will allow understanding the potential development of underground railways and the future uses of existing networks towards a sustainable urban environment convenient for each resident. Materials and methods. The evaluation of the relationship was conducted retrospectively using the regression analysis method. The annual passenger flow of underground railways was chosen as a dependent variable, as it is less affected by random factors, compared to average daily variables. The living space of buildings within walking distance of underground railway stations was taken as an independent variable. Major social factors that may influence passenger flows were also taken into account. Results. For the period from the opening of the underground railway to the present day, the relationship between living spaces within walking distance of underground railway stations and passenger flows was identified for Ekaterinburg and Kazan. From 2005 to 2019, the relationship has been tracked for Novosibirsk with account taken of the effect of the benefit monetization reform and restrictive measures related to the COVID-19 pandemic. This dependence has not been identified for Samara and Nizhny Novgorod. The radii of walking distances from the stations, having the greatest impact on the passenger traffic, were identified for several cities. Conclusions. The residential function is not a universal factor determining passenger flows of underground railways in regional Russian cities. Social factors, affecting large segments of the population, such as monetization reforms, have a substantial effect. Further research is planned to evaluate other factors that influence passenger flows of underground railways in Samara and Nizhny Novgorod.
Legislative and scientific aspects of selecting general contractors for construction work on capital construction projects
Authors:   Moscow State University of Civil Engineering (National Research University) (MGSU), Reshetova Anna Yu.
Published: June 2022

Introduction. The author addresses the choice of corporate general contractors participating in bidding for the construction of capital construction projects (CCP). The criteria evaluation pattern, employed by the customer pursuant to the effective legislation of the Russian Federation, is presented. The author has studied the criteria evaluation mechanism, applied to corporate general contractors in the course of implementation by the customer of the procurement procedure for the construction of facilities. Materials and methods. Legislative and subordinate acts, results of scientific research have been analyzed. The author has analyzed the process of tendering for public procurement contracts on the performance of work on the construction of capital construction facilities. Criteria evaluation problems, arising in the process of selecting general contractors, were identified. The benchmarking method was proposed to assess corporate general contractors. Results. Factors, influencing the quality of construction work, were presented. The author suggests consolidating them into a system of evaluation criteria and integrated into the “quality of construction work” criterion in the effective legislation. In addition, it is necessary to evaluate any procurement procedure for construction work using such parameters as “the qualification of the bidder”, “financial resources, equipment and other material resources of the organization”. Conclusions. Thanks to the proposed system of evaluation criteria, the mechanism of selecting general contractors will be more distinct, comprehensible and transparent. The system of criteria selection and evaluation, applicable to construction companies, should be simple and comprehensible not only by the customer, but also by the contractor. It is advisable to avoid using numerous mathematical formulas to calculate the rating of general contractors. Further relevant areas of research have been formulated, including the evaluation of qualitative components of assessment criteria applied to construction organizations and the issuance of their quantitative characteristic (weight significance) using the method of the full factorial experiment.
Numerical calculation of steel-concrete structures
Authors:   Moscow State University of Civil Engineering (National Research University) (MGSU), Tusnin Alexander R.
Published: June 2022

Introduction. Steel-concrete structures are composite systems composed of steel beams and a reinforced concrete slab. The reliable transfer of shear forces between the beam and the slab is required for the structure to behave efficiently. Towards this end, anchoring devices are used to ensure a connection between the beam and the slab. The design of a steel-concrete beam, composed of a reinforced concrete slab and steel beams, having bent sections, is considered. The steel-concrete beam is a system of galvanized bent steel beams placed in parallel and partially embedded in the 90 mm thick concrete slab made of B25 concrete. Shear forces are transmitted due to adhesion between galvanized steel and concrete without anchoring devices or the additional treatment of the beam surface. Materials and methods. The samples, whose flat galvanized plate had been embedded in concrete, were tested to identify actual adhesion forces. Finite element models (FEM), developed using various software packages, were assessed. FEM parameters that ensured the accuracy, acceptable for practical use, were identified. Results. The strength of adhesion between the steel plate and concrete was experimentally identified for different options of its attachment to concrete. The mesh pattern was identified for the plate for the case when 3D finite elements were used. Conclusions. A steel-concrete beam with a span of 6–8 m, bent galvanized sections partially embedded in the reinforced concrete slab with a thickness of 90 mm was developed. The author experimentally identified the shear resistance of a galvanized steel plate embedded in concrete, which reached 0.248 to 0.415 MPa depending on how the surface of the steel plate embedded in concrete was prepared. Numerical models were tested using different computational packages designa­ted for the calculation of steel-reinforced concrete beams. The author suggests FEM improvements on the basis of numerical calculation methods applied with due regard for the experimental data obtained during the testing of the full-scale structure.
An integrated approach to the assessment of construction life cycles using software packages at the design stage
Authors:   Peter the Great St. Petersburg Polytechnic University (SPbPU), Kalinina Aksin’ya V. , Petrochenko Marina V.
Published: June 2022

Introduction. The article focuses on the relevance of the Life Cycle Assessment (LCA) method, used to quantify the environmental impact of a construction project at the design stage. LCA must be addressed in the process of designing buildings that will apply for green building certificates. The use of LCA software is an essential factor for obtaining LCA scores required for the majority of green building certificates. Materials and methods. The authors take advantage of various software packages, that make calculations and assess carbon emissions at each project stage. One of the software packages used by the authors is One Click LCA (2015). Results. The results of carbon emission calculations, made using One Click LCA (2015), are presented graphically in the form of carbon emission charts broken down by the life cycle stages (LCS); structural elements presented as comparative charts depending on different characteristics. The software allows assigning categories to buildings depending on their carbon emissions and impact parameters such as the Global warming potential (GWP), the Ozone Depletion Potential (ODP), the Acidification Potential (AP), the Eutrophication Potential (EP), depletion of non-renewable energy sources, etc. Conclusions. Software packages, used to assess life cycles of buildings, accelerate the calculation of carbon emissions, which can, in turn, streamline the selection of optimal engineering solutions for construction projects and minimize environmental impacts of buildings. It’s been found that accurate LCA calculations require comprehensive information about construction projects, including data on construction materials, energy and water consumption, as well as construction site operations. In the context of Russia, calculations are more problematic, since most manufacturers do not have construction materials databases, that contain information on carbon emissions. If manufacturers invest in the issuance of environmental product declarations (EPD), calculations of carbon emissions will be trustworthy.

Published: June 2022

Introduction. An air conditioning system is the costliest engineering system in shopping and office centres. Buildings of this type have internal heat gains throughout the year. These heat gains are substantial because of the large number of people, the high level of artificial lighting, the availability of various items of equipment, and the heat gain from solar radiation. An air conditioning system known as ventilation cooling is of interest. It is not new; its energy assessment is quite high. The same system is under consideration, but it is evaluated from the economic perspective in the Moscow prices of 2021. Materials and methods. The problem is solved by applying a computational method to the case of a 35-storey office building in Moscow. Different values of the outdoor air temperature are studied to implement transition to ventilation cooling. Alternative options for the installation of dry coolers are compared, since they affect the length of routing of cooling circuits. Costs are calculated for all options under consideration. Results. Some results are presented as figures showing the costs of alternative air cooling systems. Conclusions. It is found that the location of dry coolers greatly affects the cost of pumping units. When comparing options 1 a, 1 b, and 1 с with the option that implies the installation of dry coolers on the building roof, the authors found that option 1 c is economically profitable at the 10 % discount. If options 2 a, 2 b, 2 c, are compared for the case when dry coolers are installed beside the building, option 2 c, that implies the transition from ventilation cooling to machine cooling at tn = 8 °C, is more economically profitable than option 2 b, when the transition occurs at tn = 5 °C, and option 2 a when the transition is triggered at tn = 0 °C.

La creatividad puede utilizarse como método para lograr el éxito escolar y promover la calidad de vida en los estudiantes universitarios. La creatividad está presente en las artes, ciencia, tecnología y la sociedad, así que es parte de la vida cotidiana solucionando problemas en sus distintos niveles, , y calidad de vida corresponde con el bienestar generalizado entendiéndose como material, físico, psicológico y social, que concierne con el estilo de vida como una propiedad individual puesto que incluye muestras de seguridad en sí mismo, salud física y productividad personal.

Este estudio se diseñó mediante un tipo de investigación descriptivo, transeccional, no experimental que tiene como objetivo correlacionar la creatividad, el éxito escolar y la calidad de vida de los educandos de nivel superior, para ello se aplicó el instrumento de investigación CEECaVi a 164 estudiantes de las Unidades Académicas de Ingeniería, Enfermería y Psicología del Campus Jalpa de la Universidad Autónoma de Zacatecas, el cual analiza la creatividad, éxito escolar y calidad de vida con 107 ítems.

Como principales resultados se encontraron relaciones entre la creatividad y el uso de la tecnología para el éxito escolar mediante el autoaprendizaje para realizar proyectos y alcanzar metas establecidas, asimismo, con la valoración que tienen los estudiantes de su propio trabajo; por otra parte, existen correlaciones negativas entre la creatividad y la procrastinación, el estrés y emociones negativas. Se concluye que el uso que los estudiantes le dan a la creatividad es autónomo y se le relaciona con el éxito en general.
