Published: October 2023

Después de la Segunda Guerra Mundial, empieza un periodo de cambios sociales y económicos en los Estados Unidos. Con el programa Case Study Houses, desarrollado por la revista Arts & Architecture, y la participación de arquitectos de renombre, se encargaron en proyectar viviendas económicas desde las nuevas formas de vivir y los nuevos métodos de producción de la posguerra americana. Mediante este análisis, la vivienda seleccionada para la investigación es la CSH#22 conocida también como Stahl House, esta casa muy reconocida de la arquitectura residencial californiana de la mitad del siglo XX fue realizada por el arquitecto Pierre Koenig. Se trata de analizar este ejemplo de vivienda como el modelo de lo que fue el American way of life en una familia moderna y la trascendencia que tuvo la arquitectura doméstica americana. De manera que, en este trabajo, la experiencia californiana es un paradigma de interés que puede ser aplicado en otros contextos, y que concibe el espacio doméstico como la expresión del modo de vida.

Authors: Santos Flávia Andréa dos , Abranches Sérgio Paulino
Published: October 2023

O presente artigo versa sobre o encontro do território das Tecnologias Digitais Móveis com o território da Educação de Jovens e Adultos, dos significados que margeiam esse encontro e como os sentidos de desterritorialização, reterritorialização e multiterritorialidade se inserem nesse diálogo. As reflexões apresentadas, decorrem dos dados obtidos através de uma entrevista semiestruturada aplicada com treze professores que lecionam nessa modalidade de ensino, nos Módulos I, II ou III. Como resultado, observou-se que a multiterritorialidade articula-se com o sentido de pertencimento construído bem como com as implicações atribuídas pelos professores ao uso dessas tecnologias na Educação de Jovens e Adultos, que envolve, por exemplo, a possibilidade de contribuir para o processo de alfabetização, minimizar as diferenças etárias-geracionais e preparar o aluno para o mundo de trabalho.

The article is devoted to the problems of increasing the energy efficiency of traction electric transmission of a shunting diesel locomotive. In the context of rising fuel costs, to maintain the competitiveness of rail transport, the issue of energy efficiency of the traction rolling stock, which accounts for about 90% of the total consumption of hydrocarbons by rail, is quite acute. At present, a number of measures have been investigated to improve the efficiency of diesel engines of locomotives, which allows getting an increase in the efficiency at the level of 1-5%. The use of new efficient types of electromechanical transducers with static converters, in turn, also enables us to reduce fuel and lubricant consumption by a diesel locomotive. However, solving the problem of energy efficiency in traction transmission of a locomotive requires a comprehensive approach. One of such approaches is the application of new types of diesel generator sets for locomotives – free-piston combustion engines with linear generators. The application of new designs of thermal engines makes it possible to significantly extend the possible limits of increasing the efficiency of diesel traction.

The paper presents results of synthesis, theoretical, and experimental studies of a robust system of active shielding of the magnetic field generated by overhead power lines with triangular conductor arrangements. The synthesis is based on the solution of a multi-criteria stochastic game, in which the vector payoff is calculated on the basis of the Maxwell equations solutions in a quasi-stationary approximation. The solution to the game is based on the algorithms of stochastic multiagent particle multiswarm optimization. The possibility of a significant mitigation of magnetic flux density and a reduction in the sensitivity of the system to the plant parameters uncertainty is shown. Three shielding coils are required to shield a magnetic field in a five-story building, and two shielding coils are sufficient to shield the same magnetic field in a single-story building. Practical recommendations are given on the reasonable choice of the spatial arrangements of the shielding coils of a robust system of active shielding of the magnetic field generated by an overhead power line with a triangular arrangement of conductors. The experimental research into the robust system of active shielding model of the magnetic field generated by overhead power lines with a triangular arrangement of conductors and two shielding coils is carried out. The comparison of experimental and calculated results of the magnetic flux density values in the shielding space shows that their spread does not exceed 30 %.

The expediency of the development of local training systems for power plant operators is considered. Principles of creating a training system for control operators of the electrical part of the power generating unit of the thermal power station have been developed. This system consists of two subsystems: a model of the electrical part of the power unit and a training subsystem. The model of the electrical part of the power unit includes models of a power system, generator, facilities, turbines, excitation systems, etc. The training subsystem allows the staff to cope with a learning process and acquire the skills necessary for control operators. The developed training system allows the staff to learn how to control the electrical part of the power generating unit during normal, special and emergency modes, such as: synchronization of the generator with the system (manual, automatic), transferring the excitation of the generator from the working excitation system to the standby excitation system and vice versa, synchronous oscillations of the system, load asymmetry, etc. The training system provides the opportunity of staff self-training, as well as objectively evaluates their knowledge of the operational control of the power unit. Its use allows the increase in the training quality of control operators of thermal and nuclear power plants.
Trust to Oneself as a Condition of Autonomy Development in Adolescence
Authors: Selezneva Yu. V. , Allenova V. S.
Published: October 2023

Introduction. The current situation places a special focus on the issues of freedom of choice, responsibility, self-actualization, and decision-making discretion. Autonomy as a new formation of the adolescence age becomes of special importance. It expresses itself in life-defining decisions when a person makes their first independent steps. In this sense, the factors that influence the development of autonomy in adolescence should be paid close attention.

Purpose. We will consider characteristics of personality autonomy with different types of trust relationships in adolescence.

Materials and Methods. The sample consists of young men and women aged 15–17 years. For the research, we used: “Self-Measurement of the Trust to Oneself” method (T. P. Skripkina); “Autonomy Questionnaire” (O. A. Karabanova, N. N. Poskrebysheva); “Examining of Trust/Distrust to the World, to Other People and то Oneself” method (A. B. Kupreichenko); “Level of Subjective Control” questionnaire (E. F. Bazhin, E. A. Golykin, A. M. Etkind). Statistical methods were as follows: The Mann-Whitney U test and the Spearman’s rank correlation coefficient.

Results. In the course of studying the impact of trust and trust relationships on autonomy development in adolescence, we justified and empirically confirmed the thesis: trust to oneself is a condition of autonomy development in adolescence, and autonomy development in this age differs according to the type of trust relationships.

Discussion and Conclusion. As appears, at the stage of adolescence trust to oneself acts as a condition of autonomy development. Different types of trust relationships create a difference in the development of personality autonomy between young men and women. The most favourable conditions for the growth of personality autonomy are indicated in the certain trust relationships in which trust to oneself dominates over trust to the world.
The Physical Self Perception Characteristics in Girls Studying at a University
Authors: Gosteva A. O.
Published: October 2023

Introduction. The perception of one’s physical image is one of the most important self-awareness components in modern girls. The perception of the body influences the individual’s emotional sphere, professional identity, and interpersonal interaction. Our work is devoted to the study of physical self perception in modern psychology. The results can be applied throughout an intervention program developed by psychologists.

Purpose. In our article, we will identify the characteristics of physical self perception in female students.

Materials and Methods. In the course of the research, full-time undergraduate students were surveyed. For the empirical study, the following methods were used: “Interpersonal Diagnosis of Personality” by T. Leary, “Body Image Questionnaire” by O. A. Skugarevsky and S. V. Sivukha, “Self-Attitude Test Questionnaire” by V. V. Stolin. For data processing, we used the Wilcoxon T test was to compare samples with pairwise conjugate variants, the Mann-Whitney U test, the Spearman rank correlation, the Kruskal-Wallis H test, the Fisher Z transformation to compare 2 correlations (from 2 samples), as well as the data factorization method. The data were processed with “SPSS” 17.0 for Windows. 60 female students from various courses from 17 to 25 years of age participated in the study.

Results. We formulated and confirmed a hypothesis on the relationship between self-attitude indicators in female students and their physical self perception characteristics. We designed and tested a package of psychodiagnostic techniques for identifying the physical self perception characteristics in female students for the first time. Therefore, it justifies the novelty of our work. Discussion and Conclusion. Indicators of self-attitude related to physical self perception characteristics were identified. We found the relationship between satisfaction with one’s body and psychological profiles of social attitudes.
Studying the Relationship between Adaptation and Mental State in Learning Activity of First-Year Students
Authors: Naydenova E. V. , Morozova A. S.
Published: October 2023

Introduction. The study is devoted to the relationship between adaptation and mental state in the learning activity process of first-year students. The functionality of students’ mental state is of great importance in effective university learning. However, this issue remains unexplored in the science field. Therefore, it justifies the relevance of our study. Data on mental state functionality, level of adaptation, and relationship between them in first-year students can be applied to arrange optimal class holding forms. The implementation of such forms implies that students can more actively participate in the classes, as well as better preserve and applicate obtained information.

Purpose. In our work, we will investigate the relationship between university and aspects of the psychoemotional state in first-year students.

Materials and Methods. First-year students (n = 31), male (n = 5), and female (n = 26), were the empirical object of the study. For the adaptation measurement, we used the “Students’ Adaptability at University” method (T. D. Dubovitskaya and A. V. Krylova) and the “Well-being, Activity, Mood” (WAM) questionnaire (Doskin et all.) for mental state assessment. The testing was carried out every day for the week, at the beginning, and at the end of the class.

Results. We found the relationship between adaptability to the group and the students’ well-being, activity, and mood. The same relationship is not observed with adaptability to the learning activity.

Discussion and Conclusion. Students’ well-being, activity, and mood have a tendency to decrease throughout the course of classes. This corresponds to the existing data on this issue. In particular, intensive mental workload impacts the increase in stress level and, as such, the decrease in psychoemotional state. The relationship between adaptability to the group and the indicators of psychoemotional state of the students was revealed. The results are explained by the greater importance of adaptation to the group to the students, then for the relatively new type of activity. Any kind of change occurring in the social environment influences first-year students’ mental state, and that is confirmed by the related studies.

Authors: Baqir Noor Fadhil , Ahmed Rasha Sabeeh , Mohsen Khaleel Ibraheem
Published: October 2023

Introduction. Perianal fistula rapidly develops an abscess, requiring surgical decompression. However, simple cases must be managed. However, for patients with renal insufficiency, MRI with contrast is contraindicated. It is proposed to use diffusion-weighted images that can diagnose anal fistulae, showing areas of high signal intensity (inflammatory tissues). The aim is to determine sensitivity of diffusion-weighted image combined with T2 turbo inversion recovery magnitude and as an alternative technique to contrast-enhanced MRI using clinical examination as a reference.

Materials and Methods. Study included fifty patients with a clinical diagnosis of perianal fistula. MRI sequences were T2 turbo inversion recovery magnitude in oblique coronal and axial planes, diffusion-weighted image, and T1 weighted image turbo spin echo (fat suppression) pre- and post-administration of contrast agents in oblique axial planes. Three radiologists evaluated the MR imaging data using a questionnaire of parameters that necessitated a binary response, “yes” or “no” answer.

Results. Diffusion-weighted image combined with axial T2 turbo inversion recovery magnitude sequence had 96.7 %. All  raters  agreed  that  it  is  sensitive  enough  to  correctly  identify  perianal  fistula  with  a  moderate  Kappa  agreement (k = 0.586)  and  p-value<0.001.  The  mean  value  of  rater's  responses  was  76.7 %  represents  sensitivity  of  diffusion-weighted  images  + T2  turbo inversion recovery  magnitude  as  an  alternative  technique  to  T1-enhanced  contrast  with moderate (k = 0.553) agreement between raters and P-value<0.001.

Discussion and Conclusion. Diffusion-weighted images and T2 turbo inversion recovery magnitude sequences exhibit comparable efficacy to T1-enhanced contrast sequences in detecting perianal fistula. This may be an option for patients with renal impairment who cannot receive an MRI contrast.

COVID-19 pandemic has affected the healthcare systems Worldwide causing not only a redistribution of healthcare resources aimed at combating the pandemic and helping patients who required emergency treatment for COVID-19, but also, to a certain extent, restricting access to consultative and outpatient centers. In addition, due to the fear of contracting an infection, patients delayed seeking qualified and timely medical care, did not go to specialized medical institutions or engaged in self-diagnosis and self-medication, which in its turn has worsened the course of certain diseases or even led to the development of life-threatening conditions. The cancellation of medical appointments, elective procedures and prescriptions as well as concerns about contracting COVID-19 when seeking medical care during the pandemic have all led to delays in diagnosis and timely provision of necessary medical care to pediatric patients. Increase in online consultations has led to a decrease in face-to-face contacts with physicians, which may have contributed to underestimation of the severity of the disease. During any infectious pandemic the social isolation undoubtedly effectively reduces the spread of infectious diseases by reducing social contacts in spite of negative consequences that affect both the healthcare system and public health: a decrease in the quality of medical services due to the redistribution of resources, refusal from seeking medical advice due to patients’ fear of contracting an infection when visiting medical institutions as well as delayed diagnosis of diseases and untimely identification of life-threatening conditions. One of such conditions is diabetic ketoacidosis (DKA). This complication is very common, has the most severe course and has greater risk for future disability and mortality during the manifestation of newly diagnosed type 1 diabetes mellitus (T1D).

"Induction curves (induction surfaces, induction sets in general) were recently introduced to provide a visual aid to examine the fractions de ning the norm of a matrix, along with the discovery and description of p-eigenvectors. In our current investigation we delve into an inverse problem, the identi cation of induction curves. Namely: could the elements of the matrix and the used power parameter p be reconstructed given the induction curve, i.e. the case of 2x2 matrices is examined. The analytic solution is not possible in most cases already in this planar setting, therefore numerical approximation methods shall be applied."

"The aim of this paper is to study the Dirichlet problem for semi-linear Stokes equations. The approach of this study is based on the operator method, using abstract results of nonlinear functional analysis. We rst study the problem using Schauder's fixed point theorem and we prove the existence of a solution in case that the nonlinear term has a linear growth. Next we establish whether the existence of solutions can still be obtained without this linear growth restriction. Such a result is obtained by applying the Leray-Schauder fixed point theorem."

Relative to the number of casualties, COVID-19 ranks among the ten most devastating plagues in history. The pandemic hit the South Asian nation of Bangladesh in early March 2020 and has greatly impacted the socio-economic status of the country. In this article, we propose a compartmental model for COVID-19 dynamics, introducing a separate class for quarantined susceptibles, synonymous to isolation of individuals who have been exposed and are suspected of being infected. The current model assumes a perfect quarantine based on contact with infectious individuals. Numerical simulation is conducted to investigate the efficiency of disease control by segregating suspected individuals and other non-pharmaceutical interventions. In addition, we assort quantitatively the importance of parameters that influence the dynamics of the system. Fitting the system to the early phase of COVID-19 outbreaks in Bangladesh, by taking into account the cumulative number of cases with the data of the first 17-week period, the basic reproduction number is estimated as 1.69.
ANALYSIS OF THE DIGITIZATION LEVEL OF SMALL AND MEDIUM ENTREPRESIS IN TOURISM. IDENTIFYING THE LEVEL OF DIGITIZATION OF BUSINESSES FROM BĂILE FELIX, BIHOR, ROMANIA
Authors: MOZA Miruna , BAN Olimpia
Published: October 2023

The topic of digital transformation in our country has had a major impact on both society and the economy, with all its sectors being a paradigm for them. At the same time, the digital transformation of our country is one of the most important components of the National Recovery and Resilience Plans. This fact is also due to the position on which Romania is ranked within the hierarchy based on the Digital Economy and Society Index (European Commission, 2021. Referring to it, we observe a less favorable position of our country, ranking 27th out of the 27 member states of the European Union (European Commision, 2022) with an annual growth lower than the other countries and less convergent. Thus, in order for the European Union to fulfill its objective of the digital decade, Romania must create the ideal context for a significant change in the pace of training and acquisition of basic digital skills. We therefore observe how the introduction of digital technology has corroborated the way tourism companies assert themselves. Digital technology has become an invaluable business tool widely used in the travel and tourism sector Lee & Wicks (2010). We are talking about an economic-social phenomenon reflected in one of the basic sectors of many nations, whose expansion was particularly pronounced in 2019, 2020, as a result of the collapse left in this industry by the COVID19 pandemic. Digital transformation represents a substantial challenge for both organizations and national economies, being a topic that has sparked interest for academic studies and researchers. Starting from this necessity and carrying out a review of the existing works on the market, it was found that there are no studies related to the digitalization level of tourism businesses in Romania. Thus, the present work evaluates, measures and quantifies the level of digitization of small and medium-sized enterprises in the field of tourism, with Băile Felix resort in Bihor county as a working sample.

Monitoreo por teledetección de la variación del almacenamiento de agua superficial en cuencas hidrográficas
Authors: Montealegre Medina Fabio Alejandro , Gaspari Fernanda Julia
Published: October 2023

La disponibilidad de imágenes satelitales en plataformas web permitió disponer de bases de datos geoespaciales para estimar balances hídricos espacio temporales en una cuenca hidrográfica, colaborando en la gestión sostenible de los recursos hídricos y el territorio. El objetivo fue aplicar técnicas de monitoreo por teledetección para definir la variación del almacenamiento de agua superficial, en la temporada húmeda del año 2017, de la subregión A1, al noroeste del Rio Salado, provincia de Buenos Aires, Argentina. El período evaluado fue entre enero y abril, debido a que se registraron emergencias de inundación, corroborada por datos pluviales del Servicio Meteorológico Nacional. Para el procesamiento se utilizaron datos de precipitación del sensor IMERG, evapotranspiración del sensor MODIS, datos de escorrentía y almacenamiento de agua superficial del sistema GLDAS 2.2. El análisis se realizó a nivel de subcuenca, debido a la variabilidad espacial de los datos. En la subcuenca 5 se indicó la menor precipitación (750 mm) y la máxima evapotranspiración (275 mm), mientras tanto en el centro de la cuenca A1 se manifestaron 835 mm de lluvia. El escurrimiento superficial mostró el máximo en la subcuenca 1 (68 mm), mientras que, en el resto de la A1, los valores se mantuvieron uniformes. Se concluye que la teledetección es una metodología óptima para la descripción del balance hídrico y aplicar técnicas de monitoreo por teledetección permite precisar la variación del almacenamiento de agua superficial, en una zona de gran extensión, representando, además, en forma fehaciente distribución de la evapotranspiración y el escurrimiento superficial.
The impact of modern Internet technology on the teaching of American voice in colleges and universities
Authors: Wang Tie
Published: October 2023

In this paper, firstly, the average prediction rating of interest points is performed by a recommendation model incorporating multiple factors through probabilistic matrix decomposition to improve the accuracy of the beauty teaching features obtained by matrix decomposition. Then, we combine the collaborative filtering recommendation algorithm and propose a recommendation model called TGSS-MF, and optimize the TGSS-MF recommendation model through the model of neural network for the sparse data problem faced by the interest point recommendation and the hidden feature vector representation problem of users and interest points, and finally use the TGSS-MF recommendation model to analyze the user needs of teachers, students and system administrators who are involved in teaching and learning. Finally, the TGSS-MF recommendation model is used to analyze the needs of users such as teachers, students, and system administrators involved in teaching and learning. A mobile teaching platform is designed to meet the characteristics of American voice teaching in colleges and universities. The performance analysis of the TGSS-MF recommendation model shows that when k=10, the accuracy and recall of the TGSS-MF model in the two data sets are 0.095 and 0.113, respectively, which are better than the other three algorithms in both accuracy and recall. This study can present more rich resources to students through modern Internet technology, which can help students learn effectiveness.

Student education management model and formation in universities based on hierarchical analysis
Authors: Liu Huajian
Published: October 2023

Information technology is of great significance in building a new college student education management model. This paper first presents the steps of constructing a hierarchical analysis method, which orders the combination of each index affecting the evaluation object to constitute a hierarchical and clear system, analyzes each element layer by layer, and calculates the weight value of each index. Then the process of the fuzzy comprehensive evaluation method is introduced, decomposing the total objective of the evaluation into a fuzzy set composed of several indicators, determining the affiliation function, and establishing the fuzzy matrix. Then the hierarchical analysis method and fuzzy comprehensive evaluation method are combined to evaluate the ability of college student education management. Finally, a new model of college student education management is proposed. Among the existing problems, 78.3% of students think that the construction of online platforms is lagging, and 89.8% think the current Internet platform lacks effective supervision. The weights of “students, education management team, family education, school management system, social environment, and education carrier” are 0.4323, 0.203, 0.08212, 0.13233, 0.10345, and 0.0687, respectively. It is not the sole responsibility of the school but requires the concerted efforts of the school, society, and family.

Family Drug and Alcohol Courts (FDAC) were introduced to England in 2008 following their development in the USA. Pilots launched across the country adopted a family-based strategy with the aim to improve outcomes for children that live with parents who misuse substances or alcohol. The numbers of children entering the care system has increased with ‘subsequent new borns’ being a particular concern frequently becoming ‘looked after’ by the state at birth. This article will focus upon an initial phase of a study that tracked the establishment of an FDAC pilot. It reveals how the FDAC team collaborated with Judges and a diversity of professionals and parents to create conditions through which ground-breaking practice was forged. The environment created is unique as it is one fully set within the context of each family’s lived experience. Through this approach parents have become full participants in court proceedings as opposed to purely subject to them. As a result, significant numbers of children have remained with or been returned to their families.

Background: Diabetes mellitus (DM) is a significant public health issue. It carries a variety of serious complications, the most prevalent of which is diabetic retinopathy.
Methods: This cross-sectional and descriptive study was conducted at primary healthcare centers (PHCs). Responses were obtained using a structured, multi-point questionnaire with closed-ended questions. Informed consent and ethical approval were obtained. The data were analyzed using Statistical Packages for Social Sciences version 26.0 (IBM Corp., Armonk, NY).
Results: Study participants comprised 103 family physicians, of whom 59.2% were male and 40.8% were female. Among them, 42.7% were practicing in rural areas. Data indicated that most participants (89.3%) had good overall knowledge regarding DM, but only 57.3% demonstrated good practice in terms of fundus examination.
Conclusion: This study indicated limitations in terms of family physicians' pattern of fundoscopy examination in their patients with DM. Establishing an optometry clinic within each PHC might be a reasonable solution to this problem.
