This article examines the influence of art and creativity in the process of formal education among undergraduate students of primary education. The use of creative techniques can be the key, which is necessary in the learning process to create conditions for organizing joint teaching activities of the teacher and independent work of students during formal education. The result can be in stimulating creative work, increasing students’ self-esteem and self-awareness, and gaining individuality. Traditional forms of teaching, including lectures and PowerPoint presentations, are no longer sufficient to adequately engage the younger generation in the digital age. So teachers need teaching methods that can engage students in real group settings and simultaneously be tested and approved. The subject of creativity in this study is acting techniques developed by teachers, directors of theatrical work, such as Stanislavsky K.S., Strasberg L., and Chekhov M.A., whose techniques were subjected to our study in the article. The techniques were studied, processed and applied within the framework of the discipline “Children’s Literature with a Workshop on Expressive Reading” in the context of formal education. To conduct research within the framework of the above discipline, practical tasks and SIW based on acting techniques were developed. The problems that students have encountered or will face when they begin to conduct pedagogical activities are indicated. Conclusions and ways of solving problems on the way of becoming future primary school teachers are proposed.

The article deals with the issue of course design management for university students of technical majors. The issue is related to the frequent notion that students do not come to the defense of their course projects on time. Similarly, to other types of independent student work, working on a course project develops creative thinking, teaches students how to solve professional problems, prepares them to preplan work and be responsible for the quality of its implementation. A violation of the work schedule and/or inability to independently complete a task accordingly is regularly observed in courses for various reasons. However, this problem indicates the under development of students' skills, such as responsibility, adaptability, independence, the ability to learn new things and find solutions in non-standard circumstances, precisely those skills that employers often find the most important. The article identifies several reasons for the mentioned problem, but the main attention is paid to planning students work, both from the instructor’s and students’ perspectives. In order to plan and control students’ time, it is proposed to apply principles of the critical chain method, which has proven its effectiveness in industry and can be useful in planning the independent work of students. Using the example of a hypothetical course project, the average distribution of curriculum time needed for solving the tasks related to the course project is shown. The time set in the curriculum is determined by the critical chain method as sufficient for working on a project. Careful planning of students' own work can allow them to complete a course project in a much shorter period of time, which eliminates the disruption of project defense deadlines.

Conflict is a condition that defines a social life. Conflicts and disagreements can arise as a result of differences in values, beliefs, personalities, goals and perceptions of individuals. In an educational organization it is common to have conflicts between teachers and administrators for various reasons. However, it is essential for both parties to cooperate, interact and work together in order to prevent or resolve conflict situations that have arisen. The purpose of the study is to try to determine the causes of conflicts between teachers and school administrators according to the teachers' perceptions. The participants of the research consisted of 30 schools from the city of Ust-Kamenogorsk, Kazakhstan, including Kazakh, Russian and Kazakh-Russian mixed schools all over the city, and 432 teachers who worked in these schools during the academic year 2019-2020. The data were collected using “Personal Information Form” and the “Reasons of Conflict Questionnaire”. The arithmetic means and standard deviation of the organizational conflict questionnaire determined the results of the study. The results of the study revealed, according to the teachers’ perspective the items that “mostly” causes conflicts in schools are the following: “Too much paperwork”, “The administrator keeps teachers under constant and tight control”, “The administrator interferences in teacher's private life”, “The administrator punishes failure rather than rewarding success”, “Differences in perception”, “The administrator is too distant from teachers”, “The administrator pretends to consult teachers when he/she makes the decision”, “The administrator looks down on teachers”, “The administrator neglects his/her responsibilities due to professional incompetence”, “The administrator’s favoritism policy”, “The parties have different views on the management methods”, “The administrator trusts only close people to him/her at school”, “The administrator always uses only written communication type”. As a result, it was concluded that Ust-Kamenogorsk has an unsatisfactory school environment which must be eliminated.

The article will be devoted to the theoretical and practical study of the relationship between spouses in marriage, the establishment of roles and responsibilities in everyday life, mutual decision-making, leisure planning, family budget management, the establishment of a system of shared values, etc. The institution of the family occupies a special place in society and for every person, the constantly growing instability of marital relations in its composition is an urgent problem that foreign and domestic scientists are currently paying attention to. In addition to the joy of reaching a new level of relations, the marriage union includes tests for the maturity of newlyweds who have to live under the new system. Of the many problems in marriage, the problem of infidelity may be the most serious. Even at all times, fidelity was considered the highest value of marriage. Although a loving marriage is an ideal that many couples strive for, in many societies love is not a requirement of marriage. However, love is an important component of marriage, often the only motive for its creation. Therefore, betrayal can lead to a serious crisis or even to the disintegration of the family. In addition to knowing about the causes, circumstances and consequences of infidelity, the properties of the spouse associated with the likelihood of infidelity, as well as the feelings and emotions of the spouse causing the state of infidelity, we also organize an experimental study to get answers to questions about how modern families are connected with the fact of infidelity, using psychodiagnostic methods aimed at determining the relationship of men and women to adultery, we conducted an analysis based on the obtained research data.

Reconstructing the Spectrum of a Polyharmonic Signal under Slow Fluctuations in the Sampling Period
Authors: Monakov A. A.
Published: May 2024

Introduction. Polyharmonic signals with a line spectrum are often encountered in practical problems. Among the examples are signals from sensors monitoring rotating elements of mechanical systems, heart rate signals, or signals of radio systems with pulse-to-pulse repetition-period staggering. Due to instable frequencies of the signal harmonics or due to fluctuations in the sampling period, the line spectrum is disrupted. These distortions can be considered as a consequence of changes in the local time scale of the processed signal. This interpretation makes it possible to use scale-invariant transforms to reconstruct the signal spectrum. Methods for reconstructing the spectrum of a signal, the sampling moments of which are unknown a priori, are based on a preliminary reconstruction of the signal and subsequent estimation of its spectrum. Existing algorithms for reconstructing a signal sampled on an uneven time grid with unknown nodes are characterized by a high computational complexity due to their iterative nature and reliance on optimization search methods.

Aim. To synthesize a non-iteration algorithm for reconstructing the spectrum of a polyharmonic discrete signal under the assumption of slow changes in the sampling period.

Materials and methods. To solve the problem, the digital Lamperti transform is implemented. The quality assessment of the proposed algorithm is realized via computer simulation using a test signal known from the literature on the digital spectral analysis.

Results. The conducted computer simulation of the proposed algorithm has proven its feasibility. The line structure of the test signal spectrum, which was distorted by slow changes in the sampling period with an amplitude of 20 % of the mean value of the sampling period, was completely restored. Errors of the frequency and power estimates of individual signal harmonics exhibit values comparable with those derived from the spectrum estimate when the signal is evenly spaced. The error in estimating the sampling period comprised 5 % of its mean value.

Conclusion. A new iteration free algorithm for reconstructing the line spectrum of a discrete polyharmonic signal is proposed. The algorithm uses the scale invariant Lamperti transform. The synthesized algorithm can be used in a simple iterative procedure to estimate changes in the sampling period.
Measuring the Elevation Angle of an Airborne Object by Phase Direction Finding in a Multi-Ring Antenna Array
Authors: Aleshkin A. P. , Vladimirov V. V. , Chestnykh A. V.
Published: May 2024

Introduction. Radar stations for surveillance of airborne objects operating in the shortwave range are characterized by a number of limited technical characteristics, one of which is the azimuth viewing sector. The use of a linear antenna array (AR) as a receiving array provides the viewing angle of only up to 60°. When modernizing the station, this limitation was removed by applying an AR with a ring structure (currently a multi-ring AR is used). In practice, after performing a number of spatial processing algorithms, the operator obtains the azimuth, range, and speed of the observed object. However, due to the peculiarities of shortwave signal propagation, the accuracy of measuring these parameters does not ensure stable tracking of airborne objects. The use of multi-ring ARs also allows the elevation angle to be measured with a subsequent calculation of the height of the object.

Aim. Analysis of the phase distribution of the incident wave at the aperture of a multi-ring AR, as well as spatial processing of the received signal using the phase direction finding method to improve the accuracy of elevation angle measurements.

Materials and methods. Computer simulation in the MATLAB environment was carried out to form phase distributions on the elements of a multi-ring array, to calculate the elevation angle using the phase method, and to form portraits of the surveyed object. This environment has been successfully used to solve a wide range of problems of varying complexity in both industry and research fields.

Results. The possibility of using the phase method of direction finding of a radiation source to improve the accuracy of elevation angle measurement is demonstrated based on the conducted computer simulation. The obtained results were verified on the example of surveying an airborne object by a shortwave radar station.

Conclusion. The results obtained proved the relevance of using the phase method when performing spatial signal processing by a shortwave radar station. The proposed method made it possible to eliminate the ambiguity in measuring the elevation angle and to increase the accuracy of its determination, which is a new result in relation to the systems under consideration.

The article presents the results of research on the toxicity determination of phytopreparations in the composition of common powdery mildew + calamus + pear Late November + bischofite; common powdery mildew + calamus + bischofite; pear Late November + bischofite, which have a universally broad spectrum of bactericidal action against Staphylococcus aureus and Escherichia coli. When studying the toxicity of phytopreparations on guppy fish, it was found that when adding the infusion to water in the composition of common powdery mildew + calamus + pear Late November + bischofite with exposures of 30 minutes and 60 minutes, all fish in a group of 10 had an adverse reaction. With an exposure of 24 hours, mortality reached up to 20 %. The highest fish mortality occurred at 24 hours in the composition of common powdery mildew + calamus + bischofite, with a mortality rate of 40 %. The composition of pear in late November + bischofite showed no signs of toxicity; all fish in the group remained alive during the study. Visually, motor activity, behavioral reactions, changes in skin pigmentation, and breathing intensity were average. The survey of skin-irritating effects of phytopreparations was conducted on laboratory animals in 20 individuals – Alaska breed rabbits. It was established that during the observation period, the following signs were absent: the presence of temperature; moderately expressed, expressed, and sharply expressed erythema; pain (with a slight thickening of the skin followed by flaking); pain, swelling, and ulcers (thickening of the skin in the application area on the rabbit). After applying phytopreparations to the skin of rabbits with exposures of 1 hour, 24 hours, 48 hours, and 72 hours, no behavioral and visual changes of an inflammatory nature were detected. When applied to the animal's skin, the investigated plant-based disinfectants do not cause irritating, necrotic, or absorptive effects. Throughout the observation period, no visible changes were observed in laboratory animals' experimental and control groups. The conducted research indicates the possibility of safe application of these plant-based disinfectants in the presence of animals.

One of the most relevant zoocides are rodenticides used to control harmful rodents. Carrying out effective deratization measures on the territory of Ukraine is especially important nowadays during the Russian-Ukrainian war. According to the reports of Ukrainian servicemen and civilians in the de-occupied territories, the population of rodents is extremely large, and not all modern rodenticide drugs lead to the death of harmful animals of these species. However, the toxicological characteristics of rodenticides take into account the fact that they can poison non-target animals. The purpose of our study was to analyze the pharmaco-toxicological characteristics of rodenticides and the main trends in the pharmaceutical market of drugs of this group registered in Ukraine as of January 1, 2024. It has been established that bromadiolone (77 %) and brodifacoum (23 %) are the main active substances in modern deratization agents. They belong to second-generation anticoagulants with a chronic mechanism of action. All registered rodenticides are produced in Ukraine and are available in various dosage forms. The low effectiveness of rodenticides can be due to falsification of starting substances for the synthesis of rodenticides, inconsistency of the required content of active substances, development of resistance of rodents to poisonous substances, etc. It is expected that the results highlighted in the article will indicate further directions in the development of new rodenticides and/or increase the effectiveness of the generally accepted scheme of deratization. In Ukraine, in the conditions of the Russian-Ukrainian war and in the post-war period, these questions are among the most significant, which scientists, pharmacologists and toxicologists, pharmacists and industry manufacturers should work on.

Background
Bilateral congenital femoral agenesis is a rare congenital anomaly. To the best of our knowledge, only three cases of simple congenital anomaly, three cases associated with femoral facial syndrome, have been reported. We describe a simple form of bilateral femoral agenesis observed in 3-month-old female baby without femoral facial syndrome and non-diabetic mother.
Objective
We report this case because it is a rare case and needs proper evaluation and management. The majority of cases, however, are sporadic, and therefore, the parents may be reassured that the risk of further offspring being affected is negligible.
Case
A 3-month-old female baby present with a complaint of short stature. The baby was born full term spontaneous labor, 2570 gram vigorous and started to cry immediately after birth. The mother has no history of diabetes, cigarette smoking, and exposure teratogens. The parents were not related by blood. X-ray examination showed bilateral agenesis of femur, normal tibia and fibula, proximal of cruris in lateral of acetabula.
Conclusion
Bilateral congenital femoral agenesis is a rare congenital anomaly. Although commonly associated with maternal diabetes mellitus, most cases have no known cause.

José Martí en el Club Crepúsculo de Nueva York. En busca de nuevos equilibrios
Authors:   Universidad de Guadalajara, Sarracino Magriñat Rodolfo
Published: May 2024

Son muchos los espacios biográficos aún no precisados en la vida de José Martí, en algunos casos debido al número exiguo de sus escritos accesibles a los investigadores y en otros por el desconocimiento de su contexto real. De ahí la importancia de las investigaciones sobre el héroe nacional cubano. Este libro permitirá al lector hacer una aproximación al momento histórico del prolongado exilio de José Martí en Nueva York y de todas aquellas astucias de las que se valía para seguir la lucha revolucionaria sin que fuera intervenido por los gobiernos de España y Estados Unidos.
La nueva representación política: algunos puntos para el debate mexicano
Authors:   Universidad de Guadalajara, Vázquez Ramos Homero
Published: May 2024

El problema que se abordará en esta investigación son los nulos mecanismos de control en el mandato representativo que existen en nuestro sistema democrático mexicano. Se probará la necesidad de contar con un poder legislativo vigorizado y con operación eficiente que cumpla con sus funciones de análisis, deliberación, discusión de los grandes problemas que afectan a la población y proposición de soluciones, asimismo que regule las facultades del Ejecutivo, vigile y controle su activación y permita, en la medida que aglutine a las fuerzas más representativas, avanzar en la democracia.
Calidad en la educación superior. ¿Qué modelo y en qué condiciones? La opinión del profesorado en Argentina, España y México
Authors:   Universidad de Guadalajara, Cardona Rodríguez Antonio
Published: May 2024

Aquí se presenta un análisis de la opinión de los docentes de Argentina, España y México, recogida mediante un cuestionario donde se les pedía su valoración sobre el efecto en la mejora de una serie de factores, la presencia de éstos en sus instituciones, su grado de identificación con distintas concepciones de la calidad y la percepción que tenían de la identificación de sus propias universidades con estas concepciones. Se aborda la discusión sobre los conceptos de calidad, plantea un marco teórico que permite interpretar los datos y sugiere nuevas preguntas. Además, la labor conjunta y coordinada en los tres países permite el análisis comparado.
La migración como factor de desarrollo. Memorias del primer Foro Internacional sobre Migración y Desarrollo
Authors:   Universidad de Guadalajara, Leal Moya Irma Leticia , Durand Jorge , Edwards Figueroa Sebastián , Albo Márquez Adolfo , García Alba Zepeda Carlos
Published: May 2024

Para un país como México, el fenómeno migratorio es un tema de especial importancia y debe ser analizado como tal. Cabe recordar que este fenómeno constituye un renglón delicado de las relaciones bilaterales con Estados Unidos, país con el que se llegan a tener coincidencias en agenda migratoria, pero también divergencias en aspectos fundamentales. En ese sentido, el Centro de Estudios Estratégicos para el Desarrollo de la UdeG llevó a cabo el Primer Foro sobre Migración y Desarrollo, donde se reunieron expertos, académicos y diplomáticos especialistas. Este libro reúne las memorias del foro, llevado a cabo en diciembre de 2010.
Stilovi poslovnog pregovaranja s kulturološkog aspekta
Authors: Čapko Zvonko , Babić Ana , Zron Anamarija
Published: May 2024

Na temelju načina, stilova i karakteristika poslovnog pregovaranja te kulturoloških aspekata, odnosno kulture visokog i niskog konteksta provedeno je istraživanje visokog menadžmenta u četirima europskim zemljama. Svrha je ovoga istraživanja popuniti istraživački jaz zbog nedovoljne istraženosti na polju stilova i karakteristika poslovnog pregovaranja s kulturološkog aspekta te obogatiti znanstveni korpus istraživanjima novijeg datuma. Provedena je metoda intervjua, komparacije, analize i sinteze kako bi se utvrdio kulturološki kontekst te spoznalo je li došlo do promjena u poslovnom pregovaranju kada se radi o sklonostima prema neformalnom uvodu u pregovaranje, tempu pregovaranja, neverbalnoj komunikaciji (gestikulacijama), sklonosti prema stvaranju osobnih odnosa, iskazivanju emocija i međusobnom darivanju. Istraživanje je pokazalo kako promjene u načinu poslovnog pregovaranja puno brže prihvaćaju zemlje nisko kontekstualne kulture, kao što su Njemačka i Švedska. Dok se zemlje visoko kontekstualne kulture, poput Hrvatske i Bosne i Hercegovine, još uvijek drže ustaljenih karakteristika poslovnog pregovaranja. Budući da su ispitivane odgovorne osobe, najveću prepreku ovom radu predstavljalo je vremensko trajanje istraživanja, s obzirom na širinu teme s usklađivanjem brojnih obveza ispitanika.

A neutron irradiation cavity for in vivo activation analysis has been characterized to estimate its dosimetric specifications. The cavity is defined to confine irradiation to the hand and modifies the neutron spectrum produced by a low energy accelerator neutron source to optimize activation per dose. Neutron and gamma-ray dose rates were measured with the microdosimetric technique using a tissue-equivalent proportional counter at the hand irradiation site and inside the hand access hole. For the outside of the cavity, a spherical neutron dose equivalent meter and a Farmer dosemeter were employed instead due to the low intensity of the radiation field. The maximum dose equivalent rate at the outside of the cavity was 2.94 microSv/100 microA min, which is lower by a factor of 1/2260 than the dose rate at the hand irradiation position. The local dose contributions from a hand, an arm and the rest of a body to the effective dose rate were estimated to be 1.73, 0.782 and 2.94 microSv/100 microA min, respectively. For the standard irradiation protocol of the in vivo hand activation, 300 microA min, an effective dose of 16.3 microSv would be delivered.
Evaluation of imaging technologies to correct for photon attenuation in the overlying tissue for the in vivo bone strontium measurement

Published: May 2024

The interpretation of measurements of bone strontium in vivo using energy dispersive x-ray fluorescence spectroscopy is presently hindered by overlying skin and soft-tissue absorption of the strontium x-rays. The use of imaging technologies to measure the overlying soft-tissue thickness at the index finger measuring site might allow correction of the strontium reading to estimate its concentration in bone. An examination of magnetic resonance (MR), computed tomography (CT) and high-frequency ultrasound (US) imaging technologies revealed that 55 MHz US had the smallest range of measurement uncertainty at 3.2% followed by 1 Tesla MR, 25 MHz US, 8 MHz US and CT at 4.3, 5.4, 6.6 and 7.1% uncertainty, respectively. Of these, only CT imaging appeared to underestimate total thickness (p < 0.05). Furthermore, an inter-study comparison on the accuracy of US measurements of the overlying tissue thickness at finger and ankle in nine subjects was investigated. The 8 MHz US system used in prior in vivo experiments was found to perform satisfactorily in a repeat study of ankle measurements, but indicated that finger thickness measurements may have been misread in previous studies by up to 17.7% (p < 0.025). Repeat ankle measurements were not significantly different from initial measurements at 2.2% difference.
Pure hydroxyapatite phantoms for the calibration of in vivo X-ray fluorescence systems of bone lead and strontium quantification

Plaster of Paris [poP, CaSO4·(1)/(2) H2O] is the standard phantom material used for the calibration of in vivo X-ray fluorescence (IVXRF)-based systems of bone metal quantification (i.e bone strontium and lead). Calibration of IVXRF systems of bone metal quantification employs the use of a coherent normalization procedure which requires the application of a coherent correction factor (CCF) to the data, calculated as the ratio of the relativistic form factors of the phantom material and bone mineral. Various issues have been raised as to the suitability of poP for the calibration of IVXRF systems of bone metal quantification which include its chemical purity and its chemical difference from bone mineral (a calcium phosphate). This work describes the preparation of a chemically pure hydroxyapatite phantom material, of known composition and stoichiometry, proposed for the purpose of calibrating IVXRF systems of bone strontium and lead quantification as a replacement for poP. The issue with contamination by the analyte was resolved by preparing pure Ca(OH)2 by hydroxide precipitation, which was found to bring strontium and lead levels to <0.7 and <0.3 μg/g Ca, respectively. HAp phantoms were prepared from known quantities of chemically pure Ca(OH)2, CaHPO4·2H2O prepared from pure Ca(OH)2, the analyte, and a HPO4(2-) containing setting solution. The final crystal structure of the material was found to be similar to that of the bone mineral component of NIST SRM 1486 (bone meal), as determined by powder X-ray diffraction spectrometry.
