Authors: FOKINA Lyudmila , PUTRIK Iurii , LIVANOVA Rimma , DROBYSHEVA Nataliya , ROSTOVTSEVA Polina , AGAMIROVA Ekaterina
Published: June 2023

The article considers human rights and freedoms in the context of ensuring the balance of public interests. The nature of law, its goals, functions, and mechanisms for implementing and influencing the actors of public life have been topical issues of the theory and practice of regulating public relations and ensuring the stability of a state-organized society. Law is not a natural but rather a social phenomenon. It reflects socio-economic conditions of society and its spiritual culture. It is transformed into a legal reality through the worldview of social actors and its acceptance as a social value that realizes the goals of life. The stability and balance of social relations include the consolidated interests of society members, their culture, and the well-being of the people. Ensuring the balance of public interests requires observance of the principles of law. Administrative-legal relations arise in a special sphere of public life in connection with the implementation of executive and administrative activities by management bodies and officials. Under these conditions, the main features of administrative-legal relations that distinguish them from other public relations are the administrative powers of official administrative bodies and the imperative method which implies the inequality of participants in public relations.

Published: June 2023

Elastomers are widely used in many industries. Their use requires thorough knowledge of their strength and stiffness parameters over a wide temperature range. However, determination of the parameters of such materials is still a challenge. Therefore, the paper presents research methodology allowing determination of the properties of rubber-like materials in a wide range of stretch and temperatures (from +50°C to −25°C) by using the example of styrene-butadiene rubber (SBR) and natural rubber (NR) elastomers. Additionally, two blends, chloroprene rubber/nitrile-butadiene rubber (CR/NBR) and NR/SBR blends, were also considered. Based on physical premises, a polynomial and Arruda–Boyce hyperelastic constitutive models parameters were determined using two different methods, namely curve-fitting and the successive response surface method.

The ban on antibiotics across the globe necessitated the need for an alternative in the production and management of animal health, and this made herbal medicines like Lagenaria breviflora validated to be an alternative. Two hundred and eight (208) day‑old Cobb 500 chickens were randomly assigned to four (4) treatment groups of Lagenaria breviflora: control (0g), 50, 100, and 150 grams per litre, with fifty‑two (52) birds each, having thirteen (13) birds per four (4) replicates. The meat was excised from the breast region of slaughtered birds on the 49th day of the experiment and evaluated for meat technological quality, oxidative stability, and sensorial profile. The data generated were evaluated using the One‑way analysis of variance (ANOVA). The highest water absorption capacity (WAC) (61.50%) and water holding capacity (WHC) (51.09%) were observed in groups 150 g Lb and 100 g Lb, respectively. Administration of 50 g and 150 g aqueous extract of Lagenaria breviflora affected (p < 0.05) the intrinsic a* (redness) meat colour but had no significant effect (p > 0.05) on its L* (lightness) and b* (yellowness). The data showed that administration of Lagenaria breviflora had no effect (p > 0.05) on the sensory profile of the breast meat. Glutathione peroxidase (1.85U/L) (p < 0.05) was highest and similar in the control and 150 g Lb group. In conclusion, to ensure improved meat quality and oxidative stability of meat from broiler chickens, the administration of aqueous Lagenaria breviflora at 150 g per litre of water is recommended.

Objectives: This experimental laboratory study aimed to compare the effect of four external irrigation protocols on bone tissue heating during guided implant drilling. Methods: Forty perforations were made in ten bovine rib specimens using customized surgical templates. Four experimental groups (n=10/group) were tested: Control group = 10-ml syringe with 25°C saline solution, Group 1 = 10-ml syringe with 10°C saline solution, Group 2 = combined external irrigation using a handpiece and a 10-ml syringe with 25°C saline solution, and Group 3 = combined external irrigation using a handpiece and a 10-ml syringe with 10°C saline solution. The temperature was measured at cervical and apical points using K-type thermocouples, a digital thermometer, and a video recorder. Data were analyzed by ANOVA and Pearson’s correlation coefficients (alpha=0.05). Results: The maximum temperature was 42°C (cervical) and 44°C (apical). No difference in temperature changes was found among groups, but the difference between bone specimens was statistically significant. Temperature and time were positively associated for most groups, mainly in the cervical region. Conclusions: All irrigation methods were equally effective in controlling the bone temperature in cervical and apical regions. However, longer drilling times caused a greater increase in temperature.

Construyendo una democracia más sustantiva e integral en ecuador: ¿y si aprendemos de la democracia comunitaria?
Authors: Madrid Andrea
Published: June 2023

El sistema de partidos políticos ha sido uno de los mecanismos de la democracia representativa para incluir la diversidad social. No obstante, bajo esta forma hegemónica de organización política han sido opacadas otras lógicas de relacionamiento surgidas de esquemas culturales diferentes. En este contexto, en 2008, la democracia comunitaria fue reconocida constitucionalmente en Ecuador, al mismo nivel que la representativa y la directa. A partir de eso, el reto a nivel país ha sido legitimar este mecanismo comunitario de ejercer la democracia, como ocurre con los otros. El objetivo del presente artículo es, por un lado, analizar cómo la democracia representativa integra “lo diferente” bajo el sistema de partidos, reflexionando sobre el cambio de paradigma que supuso el reconocimiento de las formas culturalmente diversas de democracias. Por otro lado, se analiza la democracia comunitaria, en la que se observan coincidencias con los planteamientos de la democracia sustantiva e integral.

La cultura popular en el “joven” Néstor García Canclini: del marxismo gramsciano al posmodernismo progresista (1977-1982)
Authors: Mitrovic Mijail
Published: June 2023

El artículo analiza el desarrollo crítico de la noción de cultura popular a partir de los primeros tres libros de Néstor García Canclini, aparecidos entre 1977 y 1982. En el marco general de la teoría social del arte en América Latina, a la que García Canclini contribuyó junto a otros intelectuales latinoamericanos, se discuten las diversas entradas que el autor planteó de cara al análisis del arte y de las artesanías en la región, en diálogo con las teorías marxistas sobre la producción cultural. Finalmente, se contrapone lo examinado entre 1977 y 1982 con los planteamientos de García Canclini a inicios de los años noventa, momento donde se proyecta globalmente como un intelectual clave en el pensamiento posmoderno desde América Latina.

Published: June 2023

Existen variadas experiencias de niños/as institucionalizados, pero hay poca documentación respecto de las vivencias post egreso que han tenido personas que pasaron su infancia en alguna residencia del Estado. Para este trabajo nos planteamos como objetivo, analizar experiencias en residencias cerradas, desde la mirada de hombres y mujeres que han egresado de la institucionalización y que en la actualidad están consolidando su trayectoria laboral y/o educacional. Utilizamos el método biográfico con foco en la experiencia de ser/estar institucionalizado y la trayectoria ocupacional post-egreso. Los principales resultados muestran que la institucionalización en niños/as provoca sentimientos de abandono, dolor durante el proceso de separación familiar. Durante la estadía en la residencia se observan valoraciones positivas y negativas. El proceso de egreso suele ser en solitario y sin acompañamiento por parte de la institución y estas personas deben convivir en un entorno sin redes de apoyo y soportar un estigma social que les causa una gran carga mental.

THE INVESTIGATION OF MODALITY AND ADJUNCT IN SPOKEN TEXT OF PROPOSING A GIRL USING WAIJEWA LANGUAGE BASED ON HALLIDAY’S SYSTEMIC FUNCTIONAL LINGUISTIC APPROACH
Authors: Ngongo Magdalena
Published: June 2023

This paper is aimed to describe modality and adjunct in spoken text of proposing girl using Waijewa language. Modality refers to degrees of indeterminacy. It is to construe the region of uncertainty that lies between ‘yes’ and ‘no’. It refers not only to verb modal but also to modality idea. Thus, modality is manifested into two ways, namely modalization and modulation. The use modality grammar enables people to emphasize what can or cannot be done on what is ordered or offered. Data informing this study were from observation by recording oral texts of proposing a girl happened in Wewewa community. These data then were transcribed and analysed based on systemic functional grammar. The results showed that the use of modality was realized simultaneously by verb such as baka amiko-ngga dede wa kadanu … ‘I will come to take my handbag…’. The use of modality showed varieties of probabilities and obligation. Modalization tended to be uttered by bride’s party whereas modulation by groom’s party. This fact indicated interpersonal relationship in which groom’s party took a position as humble as possible in speaking and usually agreed everything stated or asked by bride’s parents. While bride’s party was dominant in speaking. This condition was influenced by honour value as one of the six values in this text. The use of adjunct related to mood adjunct that covered modal adjunct such as probability, usuality, obligation, obviousness, intensity, and polarity; and comment adjunct such as admissive, desiderative, entreaty, evaluative, opinion, predictive, persuasive, and presupposition.

Published: June 2023

Language exposure and learning motivation are two of the most essential aspects in learning any language. In English language acquisition, the development of these two components facilitates the development of other language skills, such as reading comprehension. In turn, reading comprehension is one of the significant indicators of fluency in second or foreign language acquisition. If a correlation can be determined between either language exposure or learning motivation and the development of reading comprehension, educators and specialists can focus their efforts on increasing these predictor variables in curriculum development to further reading comprehension and, ultimately, fluency. This study focused on the reading comprehension of senior high school students in Palembang, Indonesia and sought to find out whether or not there was any significant correlation between students’ English language exposure and reading comprehension, students’ learning motivation and reading comprehension, and among the predictor variables (English language exposure, learning motivation) and the criterion variable (reading comprehension). The samples of this study were 210 eleventh graders in SMA Unggulan, a high-performing senior high school in Palembang. The data were analyzed by using correlational and regression analyses. The findings showed significant positive correlations among English language exposure, learning motivation, and reading comprehension. The contribution of English language exposure to reading comprehension was 41.8%, while the contribution of learning motivation to reading comprehension was 51.7%. Moreover, the contribution of predictor variables to the criterion variable was 58.9%.

TEACHERS’ PERCEPTION TO CLIL AND WEB-BASED MATERIAL IMPLEMENTATION IN A PRIMARY SCHOOL
Authors: Waloyo Alimin Adi , Khoiriyah Khoiriyah , Farah Rafika Rabba
Published: June 2023

Primary school teachers have a crucial role to support CLIL and web-oriented media implementation in class. CLIL approach pedagogically offers double advantages; English competence and content development. This pedagogical approach leads to sufficient English input at the early stage of learning which makes primary learners able to shift the paradigm that English is a challenging language to learn. More importantly, primary school learners can take the advantages of the Information and Communication Technology (ICT) part of their daily use for the sake of CLIL, so learning can be fun and enjoyable. Nevertheless, much of the previous research in Indonesian context gives limited attention to how primary school teachers perceived CLIL interwoven into ICT based media.) that situation led into this research. Also, this research is expected to encourage the CLIL application in formal education, particularly in primary levels due to time efficacy and effectiveness. The involved participants were 12 primary school teachers in a primary school in Malang. A 14-item Likert-Scale questionnaire and FGD were applied to collect the data. It was found that the teachers perceive the CLIL and web-based media positively, but they would reconsider to implement it in their class due to English competency reasons and material design issue, facilities, and school support. Therefore, hybrid CLIL implementation and teachers’ collaboration are suggested.
Comparative legal analysis of consumer protection in the field of trade in the post-Soviet countries
Authors: Topilin Igor Vitalevich
Published: June 2023

The subject of the study is the legal regulation of consumer protection in the field of trade in the post-Soviet countries. The object of the study is the social relations arising from the protection of consumer rights in the field of trade. The author examines in detail the civil law regulation of consumer protection in the field of trade in the post-Soviet countries. Particular attention is paid to the subject matter, subject matter, form, essential terms of the retail sale contract, as well as the seller's pre-contractual obligation, the right to exchange goods of proper quality, unilateral termination of the contract, penalty, etc. When writing the work, the following methods were used: universal systematic method of cognition, comparative legal, formal legal methods, as well as the method of logical analysis of normative legal acts. The analysis of the legislation of the post-Soviet countries shows that the deviation from the principle of equality of participants in relations and freedom of contract on the issue of concluding a retail sale contract was carried out in favor of the consumer by establishing additional guarantees. The degree of deviation from the principle of equality of participants in relations and freedom of contract on the issue of concluding a retail sale contract in favor of the consumer in the post-Soviet countries differs. The legislation of the Russian Federation, to a greater extent than in other post-Soviet countries, establishes guarantees for consumers: the pre-contractual obligation of the seller to provide the necessary and reliable information about the product, the right to exchange non-food goods of proper quality, the right to unilateral termination of the retail sale agreement in the event of the purchase of goods of inadequate quality, the right to a legal penalty, the right to compulsory compensation for moral damage, the establishment of a limited period for satisfying the consumer's requirements by the seller, exemption from payment of state duty and alternative jurisdiction over consumer protection claims, a fine for non-fulfillment of the consumer's requirements on a voluntary basis.
New trends in extremist and terrorist crime and measures to counter threats to national security
Authors: Ul'yanov Mikhail Vladimirovich
Published: June 2023

The author analyzes the current state of extremist and terrorist crime, as well as the main trends in the commission of individual crimes in 2022 and 2023. The choice of this time period is due to the increased threats to the national security of the Russian Federation. Attention is drawn to the indicators of crimes provided for in Articles 205, 205.2, 281, 357 of the Criminal Code of the Russian Federation. Based on the evaluation of statistical data, information about the current criminogenic situation was obtained. There was a slowdown in the growth rate of the number of public calls for extremist activity (Article 280 of the Criminal Code of the Russian Federation) and the facts of incitement to hatred or enmity (Article 282 of the Criminal Code of the Russian Federation). The intensification of terrorist and sabotage activities is stated. The materials of separate foreign studies concerning destructive activity in the information sphere are analyzed. Conclusions are drawn about the need to consider extremist and terrorist activities in the context of information warfare and the use of information weapons. With this in mind, it is proposed to take a number of measures in the field of information security. As a measure to counteract new threats to national security, the urgent need to systematize and publish information that became known during the investigation of criminal cases initiated on the facts of the genocide of the Russian-speaking population in the period from 2014 and the Soviet people during the Great Patriotic War is called. It is proposed to consider the issue of securing in Russian legislation the powers of the Security Council of the Russian Federation to declare a State carrying out terrorist activities as a sponsor of terrorism.

Authors: YANG Xinyu , NEMLİOĞLU İlayda
Published: June 2023

This paper investigates the presence of the Monday effect in the American and Chinese stock markets. The data uses the Russell 1000 index from the American stock market, as well as the Gem composite index from the Chinese stock market in the period 2012 to 2021. Moreover, this paper chooses the GARCH model and the ARMA-GARCH model to investigate the Monday effect in two different stock markets. As a result, there is no evidence to find the presence of the Monday effect in the two stock markets. Nonetheless, there is still the existence of the calendar effect in the two stock markets. We ensure the credibility of results by checking for the potential bias of COVID-19 pandemic, by omitting the last two years from the data and also changing the estimation method to OLS. Results remain parallel to our main empirical findings.
Tax Expenditures as a Rupture of Fiscal Democracy
Authors: AKDURAN EROL Özgün
Published: June 2023

Although each new administration claims to craft its own budget, in reality, spending plans always follow the choices made by its predecessors. To evaluate how much of a country's current budget is allocated to projects that do not need congressional approval or, more technically, to mandated expenditure programs, the fiscal democracy index was created. The Fiscal Democracy Index is calculated by subtracting mandatory spending and debt interest from total government revenues. The number reflects the amount of money left over from taxes that can be used for discretionary government programs. The ratio of the remaining public revenues to the total public revenues is the fiscal democracy indicator. Yet, tax expenditures may occur at any time during the fiscal year. Tax expenditures, on the other hand, are not always held to the same standards of transparency and accountability as other types of government spending. In this study, which aims to examine fiscal democracy in Turkey by deeming the impact of tax expenditures, we observed that Turkey's fiscal democracy index might be higher when considering tax expenditures. As a result, reducing tax expenditures will increase fiscal democracy.
Age-defying fitness: How can combining resistance and aerobic exercise help elderly adults increase muscle strength?
Authors: Gunawan Gunawan , Saparia Andi
Published: June 2023

The population of elderly individuals in the village of Tinggede, Indonesia, continues to increase. It is crucial for the ageing population to maintain good fitness throughout the ageing process. Ageing in the elderly encompasses a range of issues, from declining motor function to muscle strength loss. Therefore, it is important for the elderly to preserve muscle strength through physical exercise to ensure independent functioning. This research aimed to investigate the effects of a combination of resistance and aerobic exercises on muscle strength in healthy elderly individuals. The study involved a sample of 30 male elderly individuals aged 60 years and older. The treatment group was given a combination of resistance exercise and aerobic exercise, while the control group was given aerobic exercise. Resistance exercise is given three times per week with a progressive increase in sets and reps. While aerobic exercise is given seven times per week for 40 minutes per session. Participants were examined for muscle strength before and after the intervention using a digital hand grip dynamometer (DHD). The analysis performed included paired t-test and independent t-test with p <0.05. The results demonstrated a significant increase in hand grip strength among the participants who underwent the exercise programme compared to the control group. These findings suggest that a progressive increase in sets and repetitions for each exercise activity can effectively enhance muscle strength in the elderly. However, it is pivotal to note that this study was limited to a single village. Nonetheless, the exercise combination proposed in this study provides valuable insights for sports medicine research and can be utilised as a reference for designing exercise programmes targeting healthy elderly individuals.
Multimodal Performance Evaluation of Urban Traffic Control : A Microscopic Simulation Study
Authors: Sautter Natalie , Kessler Lisa , Belikhov Danil , Bogenberger Klaus
Published: June 2023

Multimodality is a main requirement for future Urban Traffic Control (UTC). For cities and traffic engineers to implement multimodal UTC, a holistic, multimodal assessment of UTC measures is needed. This paper proposes a Multimodal Performance Index (MPI), which considers the delays and number of stops of different transport modes that are weighted to each other. To determine suitable mode-specific weights, a case study for the German city Ingolstadt is conducted using the microscopic simulation tool SUMO. In the case study, different UTC measures (bus priority, coordination for cyclists, coordination for private vehicle traffic) are implemented to a varying extent and evaluated according to different weight settings. The MPI calculation is done both network-wide and intersection-specific. The results indicate that a weighting according to the occupancy level of modes, as mainly proposed in the literature so far, is not sufficient. This applies particularly to cycling, which should be weighted according to its positive environmental impact instead of its occupancy. Besides, the modespecific weights have to correspond to the traffic-related impact of the mode-specific UTC measures. For Ingolstadt, the results are promising for a weighting according to the current modal split and a weighting with incentives for sustainable modes.
Automatic Design of Optimal Actuated Traffic Signal Control with Transit Signal Priority
Authors: Keblawi Mahmud , Toledo Tomer
Published: June 2023

In traffic networks, appropriately determining the traffic signal plan of each intersection is a ünecessary condition for a reasonable level of service. This paper presents the development of a new system for automatically designing optimal actuated traffic signal plans with transit signal priority. It uses an optimization algorithm combined with a mesoscopic traffic simulation model to design and evaluate optimal traffic signal plans for each intersection in the traffic network, therefore reducing the need for human intervention in the design process. The proposed method can simultaneously determine the optimal logical structure, priority strategies, timing parameters, phase composition and sequence, and detector placements. The integrated system was tested by a real-world isolated intersection in Haifa city. The results demonstrated that this approach has the potential to efficiently design signal plans without human intervention, which can minimize time, cost, and design effort. It can also help uncover problems in the design that may otherwise not be detected.
Delineation of Traffic Analysis Zone for Public Transportation OD Matrix Estimation Based on Socio-spatial Practices
Authors: Moghaddam S. M. Hassan Mahdavi , Ameli Mostafa , Rao K. Ramachandra , Tiwari Geetam
Published: June 2023

This paper aims to develop and validate an efficient method for delineation of public transit analysis zones (PTTAZ), particularly for origin-destination (OD) matrix prediction for transit operation planning. Existing methods have a problem in reflecting the level of spatial precision, travel characteristics, travel demand growth, access to transit stations, and most importantly, the direction of transit routes. This study proposes a new methodology to redelineate existing traffic analysis zones (TAZ) to create PTTAZ in order to allocate travel demand to transit stops. We aim to achieve an accurate prediction of the OD matrix for public transportation (PT). The matrix should reflect the passenger accessibility in the socioeconomic and socio-spatial characterization of PTTAZ and minimize intrazonal trips. The proposed methodology transforms TAZ-based to PTTAZ-based data with sequential steps through multiple statistical methods. In short, the generation of PTTAZ establishes homogeneous sub-zones representing the relationship between passenger flow, network structure, land use, population, socio-economic characteristics, and, most importantly, existing bus transit infrastructure. To validate the proposed scheme, we implement the framework for India’s Vishakhapatnam bus network and compare the results with the household survey. The results show that the PTTAZ-based OD matrix represents a realistic scenario for PT demand.

Microfluidics has emerged as a powerful technology with diverse applications in microbiology, medicine, chemistry, and physics. While its potential for controlling and studying chemical reactions is well recognized, the extraction and utilization of the vast amounts of high-quality information generated within microfluidic devices remain challenging. This is mainly due to the limited tools available for in situ measurements of chemical reactions. In this study, we present a proof-of-concept spectIR-fluidic reactor design that combines microfluidics with Fourier transform infrared (FTIR) spectroscopy for in situ kinetic studies of fast reactions. By integrating a multi-ridge silicon attenuated total reflection (ATR) wafer into the microfluidic device, we enable multi-point measurements for precise reaction time monitoring. This work establishes a validated foundation for studying a wide range of chemical reactions using ATR-FTIR spectroscopy, which will enable simultaneous quantification of reagents, intermediates, and products. The spectIR-fluidic platform offers customizable designs, allowing for the investigation of reactions with various time scales, and has the potential to significantly advance reaction optimization and pathway exploration.
DESIGN OF AN APTAMER BY SHAPE COMPLEMENTARITY MAXIMIZATION FOR INSULIN BINDING
Authors: Kniga Artem E.
Published: June 2023

In this paper, we propose to use parametrized secondary structure as low-dimensional space during optimization of aptamer sequence. We are testing the efficiency of a simple approach that directly maximizes shape complementarity on the intermolecular interface. From a library of symmetric parametrically designed structures, we identified a ssDNA sequence binding human insulin. Using molecular dynamics, we got an estimation of its binding affinity to be Kd = 6 μM.

The Wittig reaction of perfluorohalobenzaldehydes was systematically studied to synthesize 2,3,5,6-tetrafluoro-4-halostyrene (TFXS) as functional monomers bearing halogen bond donor sites. The reaction proceeded efficiently in tetrahydrofuran using 1,1,3,3-tetramethylguanidine as the organic base. Correlation analysis quantitatively identified three key factors required to obtain TFXS in reasonable yields. The present approach not only contributes to the study of halogen bond-based functional molecules but also presents digitalization as a potential strategy in small molecule synthesis.

Single-walled carbon nanotubes (SWNTs) possess exceptional physical and optical properties that make them promising for biomedical and engineering applications. Chirality-pure and enantiopure SWNTs are of particular interest. While single-stranded DNAs were shown to differentially bind and sort SWNTs, the underlying mechanism is not well understood. In this study, we used molecular dynamics simulations to investigate the binding of single and multiple DNA nucleotides to two (7,5) SWNT enantiomers, E1 and E2. Our simulations reveal that nucleotide bases stack closer to the surface of the E2 than the E1 enantiomer. Surprisingly, chiral single and dinucleotides did not exhibit enantiomer-dependent preferences in angular orientations on the SWNT surface. However, ATT trinucleotides exhibited differences in preferred orientations and arrangements of sugar atoms when bound to SWNT enantiomers. Our results suggest that preferred arrangements of DNA sugar moieties may be an important parameter that contributes to the differential binding of DNAs to SWNT enantiomers.
Experimental Study and Turbulence Dissipative Scale Modelling of the Rapid Micromixing of Impinging, Paper-Thin Sheets of Liquids
Authors: Demyanovich Robert
Published: June 2023

The impingement of thin liquid sheets produces high energy dissipation rates, which greatly increase the rate of mixing [1,2]. The energy released by the impingement is dissipated within approximately one turnover time of the largest eddies. As a result, micromixing was studied using a simple model that assumes diffusion of species in slabs of fixed thickness (2L), which are generated within the impingement zone. The experimental study followed the progress of an acid-base neutralization containing a fluorophore. A simulation, which included a module for calculating the fluorescence, determined 2L for experimental energy dissipation rates (ϵ) ranging from 5,000 to 7,700,000 W/kg. 2L was found to lie in the range of turbulence dissipative scales less than the Taylor microscale but greater than the Kolmogorov microscale (η). Additionally, the results provided a clear definition of the large eddy Reynolds number (Re) of impinging sheets which previously was uncertain [2]. 2L/v' was found to be a function of Re to the negative 1/4 power and and ν⁄ϵ to the 1/2 power where v' is the velocity associated with the turbulent kinetic energy and ν is the kinematic viscosity. Similar to η/Λ, 2L/Λ is a function of Re to the – 3/4 power, where Λ is the size of the large energy-containing eddies.

Este estudio tiene como objetivo identificar las competencias de comportamiento relevantes para los profesionales de las tecnologías de la información (TI) y determinar si existe una brecha entre las competencias desarrolladas por la academia y las requeridas por el mercado laboral en Costa Rica. Para ello, se llevó a cabo un análisis que involucró a cuatro grupos de interés: la literatura, las bolsas de empleo, los perfiles de egreso de las carreras de TI en universidades públicas, así como a los directores y coordinadores académicos de dichas universidades. Durante este análisis, se identificaron 45 competencias de comportamiento, de las cuales solo tres coincidieron en su categorización como de alto o moderado grado de importancia. Cabe destacar que no se encontró un conjunto homogéneo de competencias para todos los grupos investigados.
La enseñanza de la programación mediante software educativo especializado y los agentes conversacionales
Authors: Ayala Cadena Omar , Aguilar Juárez Irene
Published: June 2023

En las actividades cotidianas de aprendizaje se generan intercambios de ideas, dudas y explicaciones entre alumnos y docentes. Estos diálogos se interrumpen por limitaciones de tiempo o espacio, pues las clases terminan y la posibilidad de preguntar a un docente durante el trabajo en casa no es posible. Para facilitar la comunicación, se han desarrollado nuevas herramientas automatizadas que aprovechan los programas de procesamiento de texto. Un ejemplo muy concreto son los chatbots, los cuales han probado su utilidad en el comercio y en la atención al cliente. Actualmente, algunas instituciones educativas exploran los beneficios de estos programas en la atención a los alumnos. En este trabajo, se describe un estudio exploratorio sobre el uso del software educativo y de los agentes conversacionales en la enseñanza de la programación; el objetivo es identificar la potencialidad de este tipo de programas que apoyarán a los docentes en la formación de los programadores y en el acompañamiento de los alumnos en la autogestión del aprendizaje. Esta investigación es relevante porque las actividades de enseñanza de la programación son un reto, sobre todo cuando el alumno de nuevo ingreso inicia su contacto con la disciplina y debe aprender definiciones y tecnicismos de los que no tiene una noción previa; además, se enfrenta a desarrollar algoritmos sin nunca haberlos usado, a comprender el uso de lenguajes de programación, a participar en procesos de software y conocer por primera vez herramientas tecnológicas, técnicas y metodologías de desarrollo.
Life Road and Way of Life
Authors:   P. G. Demidov Yaroslavl State University, Kozlov V. V.
Published: June 2023

The analysis of empirical and theoretical works has shown that when specifying particular personality traits determining the choice of way of life personality determinants are not considered as a system of interrelations of motivation and axiological spheres of personality, quality of actual life, assessment and relations of life spent. The author views way of life as perception of one’s own future having its goal, as well as the way to achieve it both in global and local aspects of a material, social, and spiritual life of personality. The empirical experience of using “Doroga zhizni” (Life Road) and “Tri tseli” (Three Goals) guided imagery techniques to visualize local goals and strategies, and “Gora lichnostnogo rosta” (Personal Growth Path) guided imagery technique and “LOCK” inventory to visualize global goals of achievement and success has shown that there are differences in the degree of personality traits evidence in people with different choice of way of life depending on dominant material, social, or spiritual identity.

Agriculture can be defined as the art, the science, and business of cultivating crops and livestock for economic purposes. At certain stages of human development, agriculture used to be the only known means of living. It is derived from the ‘Latin’ terms ager referring to the soil and culture to its cultivation. Agriculture is a broad term encompassing all aspects of crop production, horticulture, live stock farming, forestry etc.
