Published: December 2024

The genetic breeding of Eucalyptus species from the subgenus Blakella, especially E. maculata and E. torelliana, is on the rise in Brazil. These species stand out for the quality of their wood and the possibility of taking advantage of the heterosis between them; however, they are still at the beginning of domestication. From the above, this study aims to: estimate genetic and phenotypic parameters; use this information to compare alternatives that can improve selection efficiency in progeny tests; and verify the viability of selecting the best individuals from each progeny in several locations. For this, DBH (cm) data were used from E. maculata progeny evaluation experiments conducted in two sites and E. torelliana in three sites, at six years of age, with 40 repetitions and of single-tree-plot. It was found that, for both species, the expected gain from selection was significant in all sites. In combined selection, the intensity of selection among the progenies was very mild (a large number of progenies being selected), even considering that the heritability on mean among the progenies was much higher than that obtained among individuals. The number of individuals selected per progeny was very different. This fact can reduce the effectiveness of recurrent selection in the medium term. Using clones as common controls is viable for selecting a single improved population based on the evaluation of progenies in more than one site.
PITFALLS OF WRITING FOR THE MEDIA: APPEALS TO EMOTION VERSUS EXAGGERATED SENSATIONALISM
Authors: ENACHE Antonia Cristiana
Published: December 2024

The present article looks into assignments written by students in the Modern Applied Languages Department of the Bucharest University of Economic Studies on a given topic. Students were asked to write an article for a newspaper, relying on the notes taken by a journalist. By quantitatively and qualitatively analysing the tasks submitted, the study sheds light on the difference between stories that are balanced and well-written, skilfully combining factual reporting with moderate appeals to emotion, and stories that go one step too far, crossing the line into exaggeration and a use of language that may come across as misplaced and may even affect the overall credibility of the story. By raising awareness of the difference between emotion and exaggerated sensationalism, the present research aims to contribute to the formation not only of a more informed and discerning readership, but also of highly skilled creators of media content.

Published: December 2024

Objective: This study aims to investigate the potential of simulation using IH Mod 2.0 as an accessible and effective tool to predict exposure to metal fumes in the SMAW welding process.
 
Theoretical Framework: Metal fumes, as pollutants generated in welding processes, can harm human health. Methods for anticipating health risks to workers stand out, providing a solid basis for promoting a safer occupational environment.
 
Method: The methodology adopted for this research comprises simulation using the IH Mod 2.0 tool to calculate the concentration of Cr, Mn, and Ni pollutants during welding for two types of electrodes in environments with and without ventilation. Concentration estimates were calculated based on data provided by the manufacturer.
 
Results and Discussion: The results revealed minimal differences between the values predicted and calculated by IH Mod 2.0, validating the tool’s capability to accurately simulate fume emissions in the SMAW welding process, even though the model does not account for the different risks associated with each contaminant.
 
Research Implications: This research's practical and theoretical implications are discussed, providing insights into how the results can be applied or influence practices in occupational health and safety. These implications could encompass metal fume exposure from welding activities in the industrial and construction sectors.
 
Originality/Value: This study contributes to the literature by simulating welding risks in an economical and efficient way, enabling preventive analysis and strategic decision-making that prioritizes workers' health and safety.

Objective: The main goal of this research is to design and simulate a unique 2x2 multiple-input and multiple-output, (MIMO) Rectangular Microstrip Patch antenna (RMPA) using an inverted array orientation approach with keen interest in improving the radiation efficiency and performance characteristics of the X- band based antenna.
 
Theoretical Framework:  This work integrates principles from Electromagnetic theory, communication theory, and basic Microstrip antenna design concepts. The framework is built upon crucial design goals such as radiation efficiency, reliability, element orientation and compactness of the antenna elements.
 
Method: This research adopted a design and simulation approach. All the antenna design modules and analysis were conducted using MATLAB R2023b simulator. Firstly, this work modelled and designed a unique single-element RMPA after iterations and optimisations of the antenna parameters to achieve enhanced performance. The achieved single element was used to model a 2x2 MIMO antenna with specified element spacing. The design applied an inverted element array orientation and streamlined feed trace mechanism to achieve a high gain and enhanced radiation efficiency.
 
Results and Discussion: The unique antenna design recorded a return loss of -15.2 dB, directivity of 7.33 dB, bandwidth of 484.8 MHz, gain of 7.16 dB, VSWR of 1.41, and radiation efficiency of 96.2%. Further analysis on the designed MIMO antenna to ascertain the mutual coupling effect showed that  Envelope Correlation Coefficient (ECC) values remained below 0.2 within the 10 GHz frequency band, representing good diversity and significantly reducing the mutual coupling effect between array elements. The Diversity Gain (DG) of 9.87 and 9.84 dB were obtained. These values are near the optimal value of 10 dB, which is diversity for MIMO applications.
 
Research Implications: The findings show the viability of the proposed design based on the performance metrics considered when compared to the previously designed Microstrip Patch Antennas (MPA). Thus, the designed MIMO antenna is suggested for use in embedded wireless communication devices within 8-12 GHz frequency bands for X-band applications such as radar systems and WiMAX.
 
Originality/Value: This study presents an innovative approach to improving the radiation efficiency of a designed 2x2 MIMO antenna. The work showed that enhancement of the radiation efficiency has a direct effect on the mutual coupling, which this work applied inverted orientation and streamlined feed trace method to minimise.

Despite the increasing use of peripheral nerve and plexus blocks, there has been limited focus on the method of placement and maintenance of
perineural catheters. It is important to consider patient comfort, efficiency, and convenience for the healthcare staff handling the catheter.
Objective: To develop and implement an effective method of placing and maintaining perineural catheters during an extended brachial plexus block
(BPB) via a supraclavicular approach. This method was based on patient and medical personnel feedback and focused on comfort, efficiency, and
convenience.
Methods: The research involved patients who had undergone surgery for fractures of the humerus and forearm bones and had received extended
BPB via the supraclavicular approach. The patients were categorized into three groups based on the method of catheter fixation. The first group
consisted of patients with catheter fixation in the supraclavicular region using an adhesive patch (n=31), the second group had catheter fixation using
a Perifix® (B. Braun Melsungen AG, Germany), a catheter securement device (n=33), and the third group had the catheter fixed with a subcutaneous
tunnel and loop (n=34). The study aimed to determine the most comfortable, effective, and convenient method of catheter fixation for extended BPB.
Two questionnaires were used to assess this, one for the patients and the other for medical personnel. The scores from both questionnaires were
combined, and a comparative analysis of the three fixation methods was conducted.
Results: In the first group of patients, the level of comfort, efficiency, and convenience was evaluated as unsatisfactory (7.0 [7.0; 10.0]); in the second
group, the assessment was deemed satisfactory (12.0 [11.0; 13.0]). However, in the third group of patients, the level of comfort, efficiency, and
convenience was rated as optimal (16.0 [15.0; 17.0], p<0.001).
Conclusion: According to the study results, the most comfortable, effective, and convenient catheter fixation method for extended BPB via
supraclavicular approach involved a subcutaneous tunnel and loop in the subclavian region.
Keywords: Prolonged brachial plexus block, catheter fixation, the optimal method of catheter fixation, comfort, efficiency, and convenience of fixation.
BEYOND SHORT-LIVED RESPONSES TO MALICIOUS CYBER OPERATIONS: THE UN GGE AND OEWG PROCESSES
Authors: CODREANU Claudiu
Published: December 2024

Western democracies imposed international sanctions, issued internationally coordinated public attributions, and/or deployed defensive cyberattacks after being hit by major cyber operations. These responses and measures have a role in reducing malicious state-sponsored activity, but their success is only temporary (if any). Bilateral agreements, such as the one between the US and China, are limited in scope, playing only a brief role. Moreover, a cyber arms control treaty could contribute to a more peaceful cyberspace, but it would be remarkably difficult to monitor compliance. Thus, in this study I shall explore the development and role of the two main United Nations processes on the security and usage of cyber technologies by state actors. In parallel, the paper will discuss the major cyber operations that have occurred during these processes, highlighting that progress has been largely obtained after escalations in cyber operations. The United Nations Groups of Governmental Experts and the Open-Ended Working Groups have achieved some limited results, but conclusive success is far from being obtained. State-actors’ behaviour in cyberspace is still an issue that needs to be regulated and normed at an international level, but it will be difficult to achieve a meaningful consensus among several loosely-formed groups of states with very different approaches to these issues. Thus, democratic states need to go beyond sanctions and use cyber diplomacy for the adoption of an international set of rules.

Cuerpos, imágenes de santos y muertos Representaciones de esclavizados y sus descendientes en la provincia de Cartagena y el valle del río Cauca del siglo XVIII
Authors: Muñoz Sandoval Luis Fernando
Published: December 2024

A partir de fuentes documentales, este libro presenta las dinámicas a través de las cuáles los esclavizados y sus descendientes de la provincia de Cartagena y del valle del río Cauca en la gobernación de Popayán del siglo XVIII, formaron sus propias representaciones de tres importantes elementos que integran una visión total del mundo: el cuerpo, las imágenes de santos y los muertos. Las representaciones aquí son entendidas como constructos históricos mentales y materiales, mediante los cuales aprehendieron, interpretaron y llenaron de sentido los múltiples elementos de su realidad. Estas representaciones sociales fundamentaron su manera de actuar frente al sistema esclavizador. Los hechos, las expresiones corporales y orales registrados en los documentos de archivo evidencian todo un proceso creativo del que fueron protagonistas, en medio del aparente rol pasivo al que los sometía el sistema esclavizador colonial. Testimonio actual de este proceso son las expresiones culturales de los pueblos afrocolombianos de ambas regiones, su espiritualidad, religiosidad, música y baile, en las que el cuerpo, los santos y los muertos hacen acentuada presencia.

Published: December 2024

In a context deeply shaped by the dynamics of globalization, contemporary society perceives itself as part of a global citizenship. In this process, education has emerged as a fundamental vehicle for promoting the comprehensive development of students as active agents in the pursuit of common goals. However, recent decades have been marked by a series of criticisms regarding the prevailing Western ideological bias in the definition, its instrumentalization in service of a capitalist model or specific state-driven objectives, as well as its exclusionary character.
Acknowledging the value of the aforementioned concerns, this research aims to provide a plausible explanation for the neutral character of the concept of Global Citizenship Education as proposed by UNESCO. Building on this premise, the study delves into educational practices within the university context. Based on an international cooperation project between Universidad Carlos III de Madrid and Universidad de La Sabana, the research seeks to offer a clarifying perspective on the current state of global citizenship, along with a series of recommendations to ensure that university internationalization efforts transcend cultural cosmopolitanism and become genuine drivers of global citizenship.
ESTUDIO MORFOFONOLÓGICO DE LAS PALABRAS SIMPLES DEL PAPIAMENTO, EN ARUBA, BONAIRE Y CURAZAO

Published: December 2024

The American continent treasures a linguistic diversity, evident in the original  languages and in languages that unite morphological, syntactic, phonological and  semantic structures of languages with different typological classifications, such as  Creole languages. These languages originate from linguistic crossbreeding and are an  element of a historical process of interrupted and restructured transmission that  differs from the genealogical models of the Indo-European languages, specifically the  Papiamentu of Aruba, Bonaire and Curaçao (known as the ABC islands). In the present  research, the morphophonological processes of vowel elision, metathesis, epenthesis  and epenthesis in the simple words of Papiamentu spoken on the above-mentioned  islands are demonstrated. The terminology to be analysed is presented, compiled from  Papiamentu-English bilingual dictionaries, a Papiamentu-English trap song and  research on the phonology and morphology of the language. The processes of linguistic  change manifested in the grammatical categories indicated are described succinctly.  For these purposes, this work employs the postulates of linguistic variation and of  researchers specialising in the phonology and morphology of Papiamentu and other  American Creole languages. The corpus consists of thirteen (13) examples of vowel  elision. In addition, the following morphological change processes are described: nine  (9) examples of metathesis, four (4) examples of epenthesis and twelve (12) examples  of epenthesis. Regarding the analysis, it is obtained that Papiamentu is a language that  starts as a pidgin of Portuguese and Spanish origin, in which the lexicon of Dutch and  African origin is added. The pattern of alternating loss of vowels according to the  etymology of the word modified in Papiamento is detected. Furthermore, the addition  of vowels in the final position of words derived from Dutch, English, due to the  adaptation to the language of the morphophonological structure of the Latin American  Romance languages, is also noted. Finally, it is noted that Papiamentu is a creole  language that varies morphologically according to the linguistic and cultural  influences received by its speakers.
ESTUDIO LEXICOGRÁFICO Y COGNITIVO DE LAS INTEGRACIONES CONCEPTUALES DE LA SÁTIRA POLÍTICA EN LAS REVISTAS LIMEÑAS MONOS Y MONADAS (1906, 1907) Y VARIEDADES (1911)
Authors: Mio Ballena Lennard Elías
Published: December 2024

This research shows the conceptual blendings of the political satirical lexicon in the  Peruvian magazines Monos y Monadas (1906, 1907) and Variedades (1911). In  addition, with the inferences made in the cognitive operation, the satirical voices  highlighted in the textual fragments are defined lexicographically. The corpus is made  up of three textual fragments from one issue of Monos y Monadas (1906), two issues  of Monos y Monadas (1907) and two textual fragments of Variedades (1911) in which  the governmental inefficiency of the Peruvian Partido Civil is criticised and in which  the social and academic everyday life of the people of Lima during the aforementioned  period is alluded to. The study uses the theories of Fauconnier and Turner (2003).  Likewise, the literary postulates of satire and the sociological postulates of everyday  life are used to historiographically justify the cognitive proposal. In parallel, the main  postulates of Lexicography are used. According to the analysis, the political satire in  Monos y Monadas and in Variedades is interpreted on the basis of conceptual  integrations based on cognitive domains and the mental spaces of culture, social  dynamics and inefficient politics as evidenced by the absence of meritocracy in Lima's  state institutions in 1907 and 1911. Moreover, the terms that evoke these conceptual  integrations have not been compiled in the twenty-third edition of the Diccionario de  la lengua española (DLE) 2014.

Published: December 2024

Socioeconomic status is considered a fundamental factor in the educational  process, directly influencing the academic performance of students at various levels  of the Mexican educational system. This element is deemed useful for defining timely  strategies that, together, will guide the development of teaching-learning processes.  This research aims to determine the influence of the socioeconomic variable on the  academic performance of 80 sixth-grade students from three primary schools in the  municipality of Navojoa, Sonora. To achieve this, theoretical methods of a  quantitative nature are applied, based on a non-experimental application technique  and a cross-sectional design. The variables are also examined through a statistical  analysis at a single point in the process to verify the correlation between them. The  results obtained reveal that the socioeconomic levels of the participants are  positioned in the highest categories, with 78.7% of them being in the top three  possible levels on the socioeconomic scale. A similar trend is observed in the  students' grade averages, with 71.2% averaging grades between 8 and 10. These  results coincide and are reinforced by the statistical values of .270* in the Pearson  correlation of the variables involved, indicating a significant correlation between  them, with a bilateral significance level of .015, which is below the minimum required .05. This represents a weak positive correlation. All the above indicates a  similarity in the behavior of the variables under study; that is, most students are  positioned in the highest levels of the socioeconomic scale, and at the same time,  they are situated in the highest passing grade averages. This information is useful to  show the importance of the context from which the students come and the impact it  will have on their academic performance, providing a starting point for making  necessary adjustments to the curriculum and creating key didactic strategies that  contribute to the pursuit of educational quality.

Intracranial pseudoaneurysms (IPAs), characterized by compromised vessel wall layers, represent <1% of all intracranial aneurysms. They often materialize along the vessel wall and are vulnerable to rupture, resulting in a mortality rate of up to 50%. Treatment is complex due to the fragility of pseudoaneurysms, the absence of a suitable surgical neck, and frequently associated intracranial atherosclerosis and calcification. This study reports a rare instance of an IPA following a microsurgical clipping of an intracranial aneurysm. A 48-year-old male with severe headache, vomiting, and brief unconsciousness was diagnosed with a ruptured anterior communicating artery aneurysm. After successful microsurgical clipping, a follow-up computed tomography angiogram revealed a new aneurysmal dilation on the anterior aspect of the pre-bifurcation segment of the right internal carotid artery (ICA). A subsequent craniotomy was performed to address the ICA pseudoaneurysm. Owing to the calcification surrounding the pseudoaneurysm, it was safeguarded with crushed muscle and cellulose fabric. Follow-ups showed no pseudoaneurysm enlargement, and the patient recovered with no neurological deficits. Iatrogenic IPAs post-aneurysmal clipping are exceptionally rare yet dangerous entities necessitating rapid intervention to minimize morbidity and mortality. Tailoring treatment modalities based on patient-specific characteristics, lesion attributes, and surgical expertise is fundamental. A cautious follow-up regimen is also suggested to monitor the pseudoaneurysm’s dimensions effectively.

С учетом констант связывания реагентов и констант скорости реакции второго порядка для взаимодействия гидроксид-иона с эфирами в воде и мицеллярной псевдофазе оценены вклады эффектов концентрирования реагентов и изменения реакционной способности НО-аниона в наблюдаемое увеличение скорости щелочного гидролиза (kнабл., мицеллярный катализ). Показано, что определяющий вклад вносит «тривиальный» эффект концентрирования, обеспечивающий рост kнабл. ≥ 10–100 раз.

The physicochemical characteristics of the alkaline hydrolysis of 4-nitrophenyl esters of diethylphosphonic, diethylphosphoric and toluenesulfonic acids in organized microheterogenic systems based on di- and monocationic surfactants are analyzed within the framework of a pseudophase distribution model. Taking into account the binding constants of the reagents and the rate constants of the second-order reaction for the interaction of the hydroxide ion with esters in water and the micellar pseudophase, the contributions of the effects of reagent concentration and changes in the reactivity of the HO--anion to the observed increase in the rate of alkaline hydrolysis (kobs., micellar catalysis) are estimated. It has been demonstrated that the determining contribution is made by the "trivial" concentration effect, which ensures growth in kobs. ≥ 10–100 times.

Authors: Karimov S. , Abdullayev E. , Gurbanov M.
Published: December 2024

In this study, we investigated the degradation properties of trichlorobenzene (TCB) as a model compound for hexachlorobenzene (HCB), utilizing benzene as the solvent, with the purpose of understanding the efficiency and pathways of gamma radiolysis in the remediation of persistent organic pollutants (POPs). Gamma radiation from a 60Co source was employed, and mainly qualitative changes in the sample solutions were analyzed using gas chromatography-mass spectrometry (GC-MS). Our findings demonstrate a 99,1% conversion of TCB, resulting in the formation of various less chlorinated benzenes (CBs) and other chlorinated and non-chlorinated organic compounds. Specifically, 39 distinct compounds were identified in the TCB + benzene system based on their mass spectra. By-products such as, 3,5-dichlorobiphenyl, 4,4'-dichloro-1,1'-biphenyl, and 3,4-dichloro-1,1'-biphenyl (PCBs) exhibit significant carcinogenic hazards. These findings underscore the potential health risks associated with the radiolytic degradation process of POPs in benzene. The G value for TCB degradation in benzene exhibits 5,47 molecules/100 eV at an absorbed dose of 3,0 kGy. However, the G value subsequently declines to 0,19 molecules/100 eV with higher doses, a trend that reflects not only the saturation of the reactive species' capacity but also the diminishing concentration of TCB, limiting further degradation despite increased radiation exposure.

В этой работе исследовалась деградация трихлорбензола (ТХБ) как модельного соединения для гексахлорбензола (ГХБ), с использованием бензола в качестве растворителя, с целью понимания эффективности гамма-радиолиза при очистке от стойких органических загрязнителей (СОЗ). Использовалось гамма-излучение от источника 60Co. Качественные изменения в растворах образцов анализировались с помощью газовой хроматографии-масс-спектрометрии (ГХ-МС). Наши результаты демонстрируют 99,1%-ную конверсию ТХБ, что приводит к образованию различных менее хлорированных бензолов (ХБ) и других хлорированных и нехлорированных органических соединений. В частности, в системе ТХБ + бензол на основе их масс-спектров было идентифицировано 39 различных соединений. Побочные продукты, такие как 3,5-дихлорбифенил, 4,4'-дихлор-1,1'-бифенил и 3,4-дихлор-1,1'-бифенил (ПХБ), проявляют значительную канцерогенную опасность. Эти результаты подчеркивают потенциальные риски для здоровья, связанные с процессом радиолитической деградации СОЗ в бензоле. Значение G для деградации ТХБ в бензоле показывает 5,47 молекул/100 эВ при поглощенной дозе 3,0 кГр. Однако значение G впоследствии снижается до 0,19 молекул/100 эВ при более высоких дозах, тенденция, которая отражает не только насыщение емкости реагирующих веществ, но и уменьшение концентрации ТХБ, что ограничивает дальнейшую деградацию, несмотря на возросшее воздействие радиации.

Дистанционное зондирование берегов Цимлянского водохранилища с помощью беспилотных летательных аппаратов (БПЛА) позволило выявить участки проявления оползневых процессов. Аэрофотосъёмка при помощи беспилотных летательных аппаратов позволила оценить развитие оползневых участков за период с 2017 по 2023 гг. Использование БПЛА позволило выделить различные типы оползней на берегах водохранилища, проследить за их развитием в последние годы. Детальные геолого-геоморфологические профили дали возможность оценить динамику оползней и изменение механизма деформаций оползней после основного смещения. Приведенные материалы показывают возможности эффективного применения БПЛА для мониторинга опасных геологических процессов и повышения достоверности данных. В пределах Цимлянского водохранилища на территории водоохранных зон воздействию оползневого процесса подвержено 396 участков береговой зоны. Практически 11,1% протяженности побережья Цимлянского водохранилища охвачено оползневыми процессами. Наибольшую площадь охватил оползневой процесс водоохранную зону Дубовского района Ростовской области. В этом районе почти половина береговой зоны приходится на абразионно-оползневые берега.

Remote sensing of the shores of the Tsimlyansk reservoir using unmanned aerial vehicles (UAVs) made it possible to identify areas of landslide processes. Aerial photography with the help of unmanned aerial vehicles made it possible to assess the development of landslide areas for the period from 2017 to 2023. Detailed geological and geomorphological profiles made it possible to assess the dynamics of landslides and changes in the mechanism of landslide deformations after the main displacement. The presented materials show the possibilities of effective use of UAVs for monitoring dangerous geological processes and increasing the reliability of data. Within the boundaries of the Tsimlyansk reservoir on the territory of water protection zones, 396 sections of the coastal zone are affected by the landslide process. Almost 11.1% of the length of the coast of the Tsimlyansk reservoir is covered by landslide processes. The largest area was covered by the landslide process in the water protection zone of the Dubovsky district of the Rostov region. In this area, almost half of the coastal zone falls on abrasion and landslide banks.

Социалдык-экономикалык системадагы ар кандай процесс стихиялуу турдө калыптанууга жөндөмдүү. Бирок, сапат стихиялуу түрдө калыптанууга тийиш эмес. Анткени бул башкарылуучу процесс жана аны эффективдүү башкаруу зарыл. Сапатты башкарууну жалаң административдик негизде жүргүзүү мүмкүн эмес. Ал бардык педагогдордун кеңири катышуусун талап кылат. Ал үчүн бул башкаруунун максаттарын жана билим берүү уюмунун иш процессинин оң натыйжасын түшүнүү зарыл. Макалада университеттеги билим сапатын башкаруунун ушул жана башка аспектилери каралган. Сапатты башкаруу университет үчүн кошумча жүк эмес экендиги, жалпысынан билим берүүнүн сапатына, анын технологиясына ылайык келген ишти уюштуруу болуп эсептелери белгиленген. Сапатты башкаруунун функциялары талдоого алынган, сапат системасын түзүүнүн принциптери жана методдору чечмеленген.

Любой процесс в социально-экономической системе способен формироваться стихийно. Однако качество не должно формироваться спонтанно. Потому что это управляемый процесс, и им необходимо эффективно управлять. Управление качеством не может осуществляться исключительно на административной основе. Оно требует широкого участия всех преподавателей. Для этого необходимо понимание целей этого управления и положительного результата рабочего процесса образовательной организации. В статье рассматриваются эти и другие аспекты управления качеством образования в университете. Отмечено, что управление качеством не является дополнительным бременем для университета, а является организацией работы, которая в целом соответствует качеству образования, его технологии. Проанализированы функции управления качеством, истолкованы принципы и методы построения системы качества.

Any process in the socio-economic system can be formed spontaneously. However, quality should not be formed spontaneously. Because it is a managed process, and it needs to be managed effectively. Quality management cannot be carried out solely on an administrative basis. It requires the broad participation of all teachers. To do this, it is necessary to understand the goals of this management and the positive result of the educational organization's workflow. The article discusses these and other aspects of quality management of education at the university. It is noted that quality management is not an additional burden for the university, but is an organization of work that generally corresponds to the quality of education, its technology. The functions of quality management are analyzed, the principles and methods of building a quality system are interpreted.

Устойчивость номадической цивилизации с присущей ей кочевнической культурой естественным образом обеспечивала устойчивость ментальных черт казахов и кыргызов. В статье выявляются и анализируются изменение некоторых ментальных черт казахского и кыргызского народов, которые проявились в результате длительной трансформации этих обществ в условиях глобализации культуры. Следует отметить, что существенное изменение менталитета казахов и кыргызов, начавшееся с определенной исторической точки и происходящее в настоящее время, сопряжено в первую очередь с количественным изменением обоих этносов. Выделены этапы изменения условий как жизни, так и ментальной составляющей. Акцент сделан на влияние ислама, советская составляющая с ее индустриально-промышленным вектором. Урбанизационные процессы и роль информации, языковые проблемы.

The stability of nomadic civilization with its inherent nomadic culture naturally ensured the stability of the mental traits of Kazakhs and Kyrgyz. The article identifies and analyzes the change of some mental traits of the Kazakh and Kyrgyz peoples, which were manifested as a result of the long-term transformation of these societies in the context of the globalization of culture. It should be noted that a significant change in the mentality of Kazakhs and Kyrgyz, which began from a certain historical point and is currently taking place, is primarily associated with a quantitative change in both ethnic groups. The stages of changing the conditions of both life and the mental component are highlighted. The emphasis is placed on the influence of Islam, the Soviet component with its industrial-industrial vector. Urbanization processes and the role of information, language problems.
