LA AUTORREGULACIÓN DEL APRENDIZAJE A TRAVÉS DEL ENTORNO SOCIAL DESDE TRES EXPERIENCIAS VIVIDAS
Authors: Rivas Mendoza Naila Milena , Sánchez Díaz Andrea Milena , Orjuela Pulido Maribel , Salamanca Murcia Sonia Paola , Fernández Guayana Tany Giselle
Published: January 2025

Este ensayo surge como una apuesta distinta de conocimiento donde las experiencias vividas por tres docentes colombianos en ejercicio de los niveles de educación preescolar, básica y media dan a conocer las realidades de sus contextos laborales y las oportunidades que se han presentado para propiciar la autorregulación del aprendizaje de sus estudiantes en medio de un entorno social hostil y con carencias de toda índole. Esta apuesta se deriva del estudio cualitativo, de corte descriptivo y diseño fenomenológico “Influencia del entorno social en la capacidad autorreguladora de los estudiantes en Colombia” llevado a cabo por 23 investigadores de la Maestría en Educación de la Corporación Universitaria Minuto de Dios – UNIMINUTO iniciado en el marzo de 2022 y finalizado en octubre de 2023. La metodología utilizada en el ensayo es descriptiva-hermenéutica debido a que se detallan cada una de las tres experiencias tal como las han vivido los docentes y posteriormente se realiza su análisis a partir de las siguientes categorías: autorregulación del aprendizaje, entorno social, práctica educativa y fenómenos sociales. En cada anécdota se reaviva la voz de los actores, pero también la intervención de la cultura y los aspectos sociales en el aprendizaje de los estudiantes y la transformación de las comunidades. En conclusión, se establece que el entorno social es indispensable en la autorregulación del aprendizaje; no obstante, la gestión de aula por parte del docente, las relaciones entre pares y el apoyo de la familia pueden mitigar considerablemente las dificultades contextuales propiciando así por la mejora de la comunidad y la transformación de sus territorios.

Published: January 2025

In the work the possibility of harmonic continuation (along the radius-vector) of anomalous potential values and its derivative from the Earth`s surface to satellite altitudes is investigated. It was performed by means of the Poisson integral, which allows solving the classical outer boundary Dirichlet problem for harmonic functions on the sphere in the form of Fourier series on spherical ones. The set of normalised harmonic coefficients of the global high-degree geopotential model EIGEN-6C4 of bounded one n = 2190 is used to compute the globular functions. The results of net anomalies of gravity force to outer space calculated at sea level and at the altitude of 500 kilometres in the form of cartograms and graphs are presented. The studies show that at distance from the Earth`s surface the characteristics of the anomalous gravity field differ in magnitude along a complex curve, and the images on the map seem to blur. Moreover, with reaching altitude up to 500 kilometres, the anomalies decreased compared to those of gravity calculated at the sea level, almost 6-7 times
Forecasting research of mixing uniformity of cerium chloride solution under microwave heating
Authors: Lv Chao , Liu Yanlong , Zhang Lu
Published: January 2025

Cerium oxide is an important strategic resource and a key raw material for
many functional materials in high-tech fields. Microwave heating is an
important method to prepare cerium oxide. In the study of cerium oxide
prepared by microwave heating, the variation of the polarity factor inside
the solution during heating was explored. In addition to thermal effects,
microwave heating also exerts electromagnetic influences that promote the
mixing of the solution. This study presents both physical experiments and
numerical simulations of the mixing behavior of cerium chloride solutions
under microwave exposure. The results reveal that under the influence of the
microwave electromagnetic field, the mixing uniformity of the solution
remains consistent and stable across the entire region. and the VMD-SSA-LSTM
model was proposed to forecast the mixing uniformity under different process
conditions. The results show that the mixing effect of cerium chloride
solution under microwave is better than that under conventional heating. The
selected forecast model saves time and energy and can accurately forecast
the above situation. In addition, the forecast effect is best when the modal
number k of VMD decomposition is selected as 3.

Published: January 2025

En el presente trabajo de investigación analizo la concepción de Antonio Caso sobre la educación, con la intención de hacer dos cosas: por un lado, comprender en qué sentido sostiene Caso que el fin último de la educación es el desarrollo de la personalidad y la individualidad; por otro lado, determinar la implicaciones que esto último tiene en su análisis sobre el problema de la educación en México (un problema que aborda fundamentalmente en sus Discursos a la nación mexicana), en relación con la caracterización de la persona y la existencia humana que aparece en dos de sus obras más relevantes, a saber, La existencia como economía y como caridad. Ensayo sobre la esencia del cristianismo (1916 y 1943) y La persona humana y el Estado totalitario (1941).
Cotidianidad en guerra: el combatiente peruano en la serranía durante la campaña de la Breña a través de sus registros testimoniales (1881-1883)
Authors: López Chang Aramis
Published: January 2025

Esta investigación se centra en reconstruir la vida cotidiana de las tropas peruanas durante la Campaña de la Breña, un período de la Guerra del Pacífico en el que las fuerzas peruanas lideradas por el general Andrés Avelino Cáceres se enfrentaron a tres expediciones militares chilenas en la serranía entre abril de 1881 y julio de 1883. A diferencia de la mayoría de los estudios que abordan, principalmente, los aspectos político-militares de la campaña, este artículo pone énfasis en el estudio retórico y discursivo de los actores involucrados, basándose en la experiencia cotidiana de la guerra a través de sus registros testimoniales. Utilizando como estrategia metodológica una diversidad de fuentes, como cartas, memorias, diarios de campaña, comunicaciones de corresponsales de guerra, documentos oficiales y observaciones de viajeros extranjeros, el estudio examina cómo los soldados y otros actores percibían y describían sus estrategias de supervivencia, la alimentación, el entorno y la violencia ejercida sobre el enemigo. El artículo concluye que esta campaña fue la más prolongada y difícil de toda la Guerra del Pacífico, debido a las extremas condiciones de vida y la naturaleza no convencional de la guerra en un terreno geográficamente desafiante y hostil tanto para las fuerzas peruanas como para las chilenas
Bases Constitucionales para la criminalización de las interferencias parentales en el Perú
Authors: Chavez Rojas Sadi Antonio
Published: January 2025

tre los problemas más críticos en el ámbito familiar, las interferencias parentales han generado graves consecuencias tanto para la sociedad como para los progenitores y, especialmente, para el niño. El objetivo de este estudio es determinar cómo las bases constitucionales y penales fundamentan la criminalización de las interferencias parentales en el derecho peruano. Se ha utilizado un enfoque documental basado en la dogmática jurídica para analizar el derecho positivo relacionado con el tema. Los resultados muestran que existen fundamentos constitucionales y penales, tanto a nivel nacional como comparado, que respaldan la criminalización de estas conductas. Las conclusiones confirman que las interferencias parentales constituyen acciones de uno de los progenitores para obstruir la relación entre el niño y su otro progenitor, lo cual justifica la adopción de sanciones punitivas severas en diversas legislaciones internacionales.
Доказательство неполноты волновой квантовой механики
Authors: Джомирзоев Субхон
Published: January 2025

Триста пятьдесят лет тому назад И.Ньютон в своей корпускулярной классической механике (ККМ) в качестве начальной величины ввёл массу и на её основе определил других корпускулярных величин своей ККМ. А сто лет тому назад корпускулярно-волновые свойства микрочастиц свидетельствовало о присущности им корпускулярно-волновых величин (КВВ), которые в качестве начальной величины имели произведению массы на длину волны. Соответственно, наподобие того, как на корпускулярных величинах была основана ККМ Ньютона, подобным образом на КВВ должны быть основаны корпускулярно-волновые механики (КВМ). Но сто лет тому назад Планк и Эйнштейн для описания корпускулярно-волнового фотона воспользовались гибридом корпускулярных величин ККМ Ньютона и волновыми величинами волновой оптики, которые априори по своему определению являлись недостаточными для описания КВВ фотона. В последующем де Бройль и Шрёдингер применили метод Планка и Эйнштейна для случая нерелятивистского электрона (НЭ),а при этом получили волновую квантовую механику (ВКМ). Но полученная ими ВКМ оказалась настоящей головоломкой и теперь сто лет после них мне удалось обнаружить, что в реальности ВКМ является всего лишь неполным вариантом КВМ НЭ. Походу удалось выяснить, что ККМ Ньютона возникает в виде частного случая КВМ макроскопического тела. В связи с этим, теперь я вроде бы Таджикистанский физик открывший КВВ и КВМ физики.

First fossil evidence of pediculochelid mites: two new species from Middle Cretaceous and Late Eocene amber revealing morphological stasis over at least 99 million years
Authors: Kolesnikov Vasiliy B. , Vorontsov Dmitry D. , Norton Roy A. , Klimov Pavel B.
Published: January 2025

We present the first fossil evidence of pediculochelid mites, describing two new species: Paralycus ekaterinae sp. nov. (Eocene amber) and P. primus sp. nov. (Cretaceous amber). The exceptional preservation of the fossils, coupled with our newly developed methodological approach for examining minute arthropods in amber, has facilitated a detailed comparative morphological assessment at a resolution comparable to that of contemporary species, providing significant insights into their anatomical features. The observed morphological continuity between fossil and modern pediculochelid mites indicates the evolutionary stability of this lineage spanning at least 99 million years. These findings not only advance our knowledge of the evolutionary history of Pediculochelidae but also offer a broader perspective on the persistence of morphological traits over extensive geological timescales. We also address the phenomenon of phoresy within Paralycus and explore its potential implications for dispersal mechanisms. Furthermore, we evaluate the relationship between the dimensions of the amber imprints and the original size of the mites, contributing to our understanding of the mechanisms of microarthropod preservation in amber.

A review of the specificity of the growth Hg1-xCdxTe layers by molecular beam epitaxy (MBE) and results of experimental studies of several Hg1-xCdxTe layers grown on CdyZn1-yTe (CZT) substrates are presented. It is well known that the performance of Hg1-xCdxTe -based detectors strongly depends on the substrate material and its orientation. CZT substrates are among the most commonly used due to their very good lattice match with Hg1-xCdxTe absorber material with different Cd content. In the present work, the authors focused on optimizing the MBE growth parameters in order to obtain the best possible crystalline quality of Hg1-xCdxTe layers grown on CZT substrates with (211)B orientation, in particular in terms of minimizing the number of defects. Experimental results of the selected structures showed that the obtained undoped Hg1-xCdxTe layers of different x have high crystallographic and optical quality, as well as good surface morphology. In particular, high-resolution X-ray diffraction (HRXRD) measurements and their analysis showed that the best structure has a full width at half maximum of rocking curve (FWHMRC) as low as 21.5 arcsec, and that the intensity distribution of diffraction peaks does not indicate the influence of mosaicisity and dislocation density.

Published: January 2025

An intensity-based refractive index (RI) sensor using a laser micromachined side-hole optical fibre (S-H OF) is presented in this paper. To achieve this, a microcavity was cut into a side surface of the S-H OF, providing access to one of the air holes within its structure. The geometrically modified fibre was then connected at both ends to a single-mode fibre for structure investigation in a system containing a supercontinuum laser and an optical signal analyser. In the next step, an immersion liquid was applied to a microcavity for RI values ranging from 1.30 to 1.57 in increments of 0.02. Power loss measurements were conducted for each RI value. Based on the obtained results, it can be concluded that an RI sensor has been successfully developed, which holds potential applications in biochemistry.

Digital entrepreneurship in rural Malaysia is limited, with small businesses struggling to use digital tools and develop entrepreneurial skills. This study explores the impact of digital literacy, entrepreneurial skills, and government support on small businesses, areas that have not been fully studied. It also looks at the role of youth in Terengganu in promoting digital entrepreneurship, in line with Malaysia’s National Entrepreneurship Policy. The study found that digital literacy and entrepreneurial competencies explain 37.3% of digital entrepreneurship, with government support and interaction effects increasing this effect by an additional 5%. Digital literacy and entrepreneurial competencies significantly impact digital entrepreneurship, with entrepreneurial competencies having a stronger influence. Government support does not impact digital entrepreneurship, but combining digital literacy with government support does. In rural areas, limited resources and knowledge may reduce the effectiveness of government aid. The government should prioritize training programs, like workshops and mentorships, to improve digital skills and business capabilities, in collaboration with academic institutions. This strategy would assist business owners in acquiring the useful abilities required for success in the digital economy. It highlights the importance of continuous learning and offers key insights for educators and policymakers to foster skills.
Third-order strong differential subordinations involving fractional integral of confluent (Kummer) and Gaussian hypergeometric functions
Authors: Preluca Lavinia Florina
Published: January 2025

For the study presented in this paper, the concepts specific to strong differential subordination theory, introduced for the second-order differential subordination case, are extended for the third-order differential subordination case. The general results presented in the first theorem proved in this investigation are applied considering the prolific operators recently introduced as the fractional integral of confluent (Kummer) hypergeometric function and as the fractional integral of Gaussian hypergeometric function, respectively, adapted considering the extra parameter imposed by the strong differential subordination theory and new third-order differential subordinations are investigated. Simple examples are also constructed but it is hoped that the results given here would inspire future similar studies for applying the new third-order strong differential subordination results using other known operators adapted in order to fit this new context.

In this paper, we introduce and investigate some new classes of mixed harmonic directional variational inequalities. Several important new problems are obtained as special cases. The auxiliary principle technique is applied to suggest and analyze some hybrid inertial iterative methods for solving the mixed harmonic directional variational inequality. The convergence analysis of these iterative methods is also considered under some mild conditions. Some special cases are also pointed out. Results proved in this paper can be viewed as a significant refinement and improvement of the known results.

Graphene is a material, which has attracted great attention of the scientific community in several fields of biomedicine, neurosciences being one of the fields holding great interest for the application of graphene-based materials and devices. Our study aimed to determine the in vivo brain tissue reaction and to study the possible impairment of memory in a long-term Graphene exposure. Towards this aim we tested the toxicity of graphene membrane in the form of few layers (few layers graphene, FLG) implanted on the frontal brain cortex of adult Wistar rats after careful durotomy. The results from this study advance our knowledge on graphene in vivo toxicity in CNS and suggest that the application of FLG as a patch on the brain cortex seems to be quite safe under the experimental conditions tested, herein as no change in locomotor activity of the rats or major histopathological reactions of the brain to the material were observed.

Published: January 2025

Gestational age, birth weight and birth length are basic somatic characteristics of each newborn. To compare the obtained data with the weight and growth curves according to Fenton 2013 (Fenton, 2013) and to analyze the occurrence of some risk factors (nicotinism, hypertension, gestational diabetes and diabetes mellitus) in mothers. The monitored group of newborns consisted of 2331 newborns admitted to the Neonatal Department of Intensive Medicine in 2012-2016 (n=2331). The number of premature newborns was 1061 and term newborns were 1270 (mean birth weight: boys – 2645.2 g, girls – 2443.79g; average birth length: boys – 45.82 cm, girls – 44.71 cm; spontaneous delivery: 1282 newborns, delivery of caesarean section: 1049 newborns). We found that both graphical representations overlap each other. We did not notice significant differences in the values of the monitored parameters. In our group of prenatally hypertrophic newborns above 97th percentile in 72 newborns were confirmed 8 cases of diabetes mellitus or gestational diabetes in the mother. In the analysis of the prenatal hypotrophic newborns below the 3rd percentile we found 71 hypotrophic newborns (6 cases with severe hypertension, 7 cases with multifetal pregnancy, 3 mothers during pregnancy smoked more than 20 cigarettes daily). The obtained result is based on the fact that data from the European population of newborns were also the basis for drawing up the Fenton graphs. We have confirmed the difference in birth weight and gender.

The study investigated effect of melatonin (MEL) on reproductive indices in untreated females mated with F1 male rats exposed in utero and via lactation to mixture of chlorpyrifos (CPF) and cypermethrin (CYP), and in the resulting F2 male rats. Sixty pregnant dams obtained via overnight mating of 72 nulliparous females with sexually mature males in a 1:1 mating scheme were divided into 6 groups of 10 animals each. Groups I (DW), II (S/oil) and III (MEL) were given distilled water (2 ml/kg), Soya oil (2 ml/kg) and melatonin (0.5 mg/kg) only, respectively, while group IV (CC) was co-administered with CPF (1.9 mg/kg) and CYP (7.5 mg/kg). Group V (MCC) was pretreated with MEL (0.5 mg/kg) and then co-exposed to CPF (1.9 mg/kg) and CYP (7.5 mg/kg), 30 minutes later. Group VI (CCM) was co-exposed to CPF (1.9 mg/kg) and CYP (7.5 mg/kg) and then treated with MEL (0.5 mg/kg) 30 minutes later. The regimens were administered by gavage once daily from gestation day 1 to postnatal day (PND) 21. The dams were allowed to deliver normally and the males F1 generation obtained from them was allowed to mate nulliparous females at PND 80 overnight in a ratio of 1:1 and some reproductive indices were thereafter evaluated. The mated females were evaluated for mating index, fertility index, gestation index and gestational length, while the resulting F2 male rats were evaluated for live birth index, viability index and sex ratio. The results revealed decreased mean gestational length, viability index and sex ratio in the CC group (p<0.05) relative to that of the other groups. Although not significant (p>0.05), the mating, gestation (pregnancy), fertility and live birth indices in the CC group were relatively lower when compared to that of other treated groups. In conclusion, alterations of reproductive indices from mating of nulliparous females with F1 male rats exposed in utero and via lactation to mixture of CPF and CYP were mitigated by melatonin.
Direct measurement of the tissue oxygenation in a newborn – new clinical applications

Published: January 2025

Oxygen is a substance needed for aerobic metabolism. The process of ischemia and reperfusion are responsible for local changes in oxygen concentrations. Both subnormal and supranormal tissue oxygenations are dangerous. Monitoring of end-organ perfusion and oxygenation is essential for patients in the intensive care unit. Knowledge of the balance between supply and consumption of oxygen in the target organ tissue is necessary. An alternative possibility of measuring tissue oxygenation is near infra-red spectroscopy (NIRS) based on tissue transparency to the near infrared spectrum (NIR, wavelength 700–1000 nm), and its absorption by the relevant chromophores (oxy and deoxyhaemoglobin). The authors summarize current knowledge and practical experiences of neonatologists using NIRS in various indications – from the evaluation of immediate postpartum adaptation to its application as a part of intensive monitoring of critically ill newborns. NIRS directly and non-invasively measures the total light signal from microcirculation (from venous, arterial and capillary nets). NIRS is a modern non-invasive, continuous, real-time and bed-side monitoring of tissue oxygenation and in the future could be part of multimodal patient monitoring.

Published: January 2025

Nanosilver particles (NSPs) used by customers may contain detergents/solvents. However, in most of the toxicological studies, nanosilvers are prepared in water and very little is known about the interaction of these agents with NSPs in causing adverse effects. The aim of this study was to investigate the interaction of NSPs and tween-20 in causing tissue injuries after inhalation. In this experiment, 16 rats were divided into four groups (n=4/group) as follows. Controls, exposed to water vapors; Tween-treated exposed to tween-20 alone (0.01% V/V); NSP-tween group exposed to 1000 ppm containing tween-20; Group treated with 1000 ppm of NSP alone. Whole-body exposure technique was performed in an exposure chamber for 16 hours (4 hours/day for 4 days). At the end of exposure, blood, liver and lungs were collected and processed for histopathological analysis. Serum glucose, total protein, alkaline phosphatase (ALP), aspartate transaminase (AST) and lactate dehydrogenase (LDH) were compared between experimental groups. The results showed no significant changes in serum ALT, AST, glucose, and albumin in rats exposed to either NSP or NSP suspended in tween-20. Whereas, lipid peroxidation in liver and lungs in rats exposed to NSPs prepared in tween-20 was elevated by 50 and 95% respectively compared to their controls (p<0.05). The interaction of tween-20 and Ag-NSP was further confirmed by observing tissue damage (histology) in tissues. In conclusion, data show that exposure to NSPs prepared in water is associated with negligible toxicity in rats. However, the toxicity of NSPs is potentiated if prepared in tween-20. It appears that Tween-20 can increase the absorption of NSPs and enhance lipid peroxidation in cellular and subcellular membranes leading to liver damage.
Manufacturability and Performance Study of Triply Periodic Minimal Surface Air-to-Air Heat Exchanger
Authors: Kancs A.
Published: January 2025

The study tests 3D printability, heat transfer characteristics and pressure drop of two types of triply periodic minimal surface heat exchanger in order to develop new flow principles for compact heat exchanger design. Various generic plate heat exchanger designs are also tested to compare to the printed alternatives. Geometry variations for heat exchangers and laboratory testing air recuperators are modelled in SolidWorks software and manufactured mostly by UV LCD and FDM additive manufacturing methods.

Digital light processing printing method has been found to be most successful in printing the TPMS structures, while using photopolymer materials. Literature studies conclude that the most promising structures are Schoen’s gyroid and Schwarz-diamond surfaces, which have been modelled and tested in several variations. Using these results, full size gyroid and Schwarz-D structure heat exchangers have been modelled, manufactured and tested. The results are compared and analysed to study the effect of advanced surface designs in heat transfer efficiency.

The obtained results can be used in compact air-to-air thermal recuperator development as well as other low pressure heat exchanger applications, as the printed TPME heat exchangers outperform the plate heat exchangers in similar dimensions.
Doctoral Supervision: A Reflection Matrix for Process and Progress
Authors: Chrysoulakis Alberto
Published: January 2025

Successful doctoral studies rely heavily on the quality of supervision, particularly the relationship between supervisor and doctoral student. This relationship influences both the doctoral process and the final product—the completed thesis. Prior research indicates that supervisory alliances play a critical role in doctoral completion, with insufficient supervisor support often cited as a key factor in student attrition. To assist supervisors, especially those new to the role, this paper proposes a structured yet flexible reflective checklist. Grounded in two systematic reviews, the checklist combines five key supervisory dimensions—relationship, domain/research knowledge, pedagogical competencies, functional aspects, and methodological understanding—with both external (e.g., departmental structures, financial opportunities) and internal (e.g., motivation, academic identity) factors affecting doctoral progression. This framework encourages supervisors to continually examine and refine their practices, thereby fostering an environment that supports effective doctoral training. Ultimately, the reflective checklist serves as a customizable tool to prompt ongoing awareness, adaptation, and development in supervisory practice.

Objective: The objective of this study is to investigate the quality of groundwater in the Estrutural Administrative Region, located in the Central region of the Federal District, Brazil, before and after the closure of the largest open-air landfill in Latin America.
 
Theoretical Framework: Brazilian legislation, Ordinance 888 of the Brazilian Ministry of Health, and CONAMA resolution 396 are highlighted for comparison with the findings of the study, providing a solid basis for understanding the context of the investigation.
 
Method: The methodology adopted for this research includes the analysis of groundwater monitoring data carried out by the Regulatory Agency for Water, Energy and Basic Sanitation of the Federal District (ADASA), carried out in two wells: shallow and deep, with 30 and 70 meters of depth, respectively, located 140 meters from the former landfill. Of the 33 parameters collected by ADASA between 2013 and 2022, 21 were analyzed.
 
Results and Discussion: The results obtained revealed that there is evidence of groundwater contamination, especially in the monitoring of shallow wells. Public policies should be implemented to protect this vulnerable population. Regarding the limitations of the study, we can mention the use of secondary data and the performance of a non-parametric test. Inadequacies in monitoring, such as the lack of standardization in the evaluation of parameters and the absence of periodic data on important parameters, such as microbiological parameters, limit the study and prevent more robust statistical analyses.
 
Research Implications: The results of this research can help in the formulation or improvement of public policies for territorial management and urban solid waste management, mainly related to the evaluation of the quality of groundwater near landfills and dumps and the conditions of access to drinking water by vulnerable populations in their surroundings.
 
Originality/Value: The study proposes a practical approach to assess the quality of groundwater in a region impacted by a landfill, based on comprehensive monitoring in the following aspects: spatial (use of a pair of shallow and deep wells); temporal (10-year series of data); qualitative (analysis of more than 20 parameters); and social (assessment of potential impacts on vulnerable populations that use groundwater for consumption). The results highlight the need for integrated action between land use and occupation management policies (in relation to vulnerable populations and occupations in risk areas); basic sanitation (mainly regarding the management of urban solid waste and the supply of drinking water); and public health (with regard to the quality of water available for human consumption).

en los últimos años varias especies de ácaros han sido informados como un problema fitosanitario de importancia para el cultivo de arándano; por su parte México se ha consolidado como uno de los principales productores de este cultivo a nivel mundial. Sin embargo, son pocos los estudios sobre la diversidad de especies presentes en el arándano en México. Por ello el objetivo de esta investigación fue conocer la diversidad y abundancia de ácaros asociados al cultivo de V. corymbosum en el estado de Michoacán (México). Se realizaron recolectas de materia vegetal en 42 huertos de 18 municipios del estado de Michoacán. Las muestras se colocaron en bolsas de plástico y se almacenaron bajo refrigeración a 4 °C. Los ácaros recolectados del material vegetal de arándano se procesaron para montaje en preparaciones semipermanentes con solución Hoyer y se identificaron mediante claves taxonómicas. Se recolectaron 625 ácaros pertenecientes a 17 especies, 12 géneros, cinco familias y tres órdenes. Las familias con mayor abundancia fueron Tetranychidae y Tenuipalpidae. Mientras que Phytoseiidae fue la más diversa con 11 especies. El municipio de Peribán y la variedad Biloxi fueron quienes presentaron la mayor diversidad y abundancia. De las especies identificadas, Oligonychus ilicis, Neoseiulus rufus, Typhlodromips jimenezi y Metaseiulus bidentatus son nuevos registros para México. Se debe profundizar en el estudio de las especies fitófagas O. ilicis y Brevipalpus yothersi, ya que pueden convertirse en plagas de importancia para el cultivo. La presente investigación será un punto de partida para profundizar en el estudio de los ácaros en arándanos en México.

Published: January 2025

Menyusui merupakan metode terbaik untuk meningkatkan angka harapan hidup bagi seorang bayi. Namun, cakupan pemberian ASI ekslusif pada enam pertama kehidupan bayi masih cukup rendah, yaitu hanya sebesar 52%. Presentasi ini saat ini masih berada jauh di bawah angka yang ditargetkan oleh Pemerintah. Maka, kegiatan pengabdian kepada masyarakat (PkM) dilakukan untuk meningkatkan tingkat pengetahuan serta keterampilan bidan mengenai teknik pijat oksitosin sebagai upaya untuk meningkatkan produksi ASI. Kegiatan PkM ini dilaksanakan untuk bidan di Puskesmas Baregbeg. Metode yang digunakan meliputi pelatihan dan penerapan teknik pijat oksitosin, termasuk penyegaran keterampilan bidan dalam melakukan pijat oksitosin. Hasil dari kegiatan PkM ini menunjukkan adanya peningkatan pengetahuan secara bertahap dan keterampilan pada sasaran dalam melakukan pijat oksitosin, dengan peningkatan pengetahuan sebesar 40%. Disarankan agar bidan mengajarkan teknik pijat oksitosin kepada setiap ibu nifas dan menjadikannya sebagai bagian rutin dari perawatan ibu nifas untuk membantu meningkatkan produksi ASI.
Ritual Bronzes of Sanxingdui and Ancient Indian Mythology
Authors:   Novosibirsk State University Novosibirsk, Russia, Varenov Andrey
Published: January 2025

The bronze skirt-wearing human figure, with talons instead of feet holding two snake-like creatures, was discovered in 1986 at JK2 sacrificial pit of the
Sanxingdui site. It belongs to the Bronze Age culture spread in the Sichuan province
of the PRC. The statue being discussed can be interpreted with the help of ancient
Indian myths about Garuda. The discovery in Sanxingdui of big bronze wheels featuring five spokes each supports such an interpretation. The statue can easily pass
between the spokes of every wheel. The results of new excavations at Sanxingdui
in 2020–2022 are briefly mentioned.
On Zhu De’s Entry into the Communist Party

The spread of Marxism in China is undoubtedly one of the most important
phenomena in the first decades of the 20th century. Its ideas became the property
of representatives of various social classes, groups and strata. And there is nothing
surprising in this — the string of a radical and, most importantly, relatively rapid reorganization of society on the principles of universal equality and justice sounded too
attractive and tempting in Marxism. At the same time, history has preserved not
so many examples of the transition to Marxist positions of those who, in the eyes of
the Chinese nation, directly and immediately personified power, domination and
tyranny. Perhaps the most notable among them was the outstanding statesman
and military figure of the CPC Zhu De.
Revision of Views on the Participation of the Republic of Korea in the Vietnam War in the South Korean Society at the Turn of the XX–XXI Centuries

During the Vietnam War, not only the United States but also a number of
countries, including the Republic of Korea (ROK), took the side of South Vietnam.
Participation in the war for the ROK had a great impact on the development of the
state. The purpose of our study is to determine the characteristic features of the
collective memory of the ROK’s participation in the conflict, which emerged during the period of the late XX — early XXI centuries. It was found that after a period
of oblivion of the theme of participation in the war and democratization of society
in the RK, interest in the events of the war increased. This led not only to a reassessment of the RoK’s role in the conflict, but also to the emergence of a plurality
of opinions in society and various kinds of conflicts on this ground that persist to
this day. Some consider participation in the war a necessary step within the framework of anti-communist policy, while others express regret and demand an official
apology for the actions of Korean troops in Vietnam.

The incredible finds of the Sanxingdui site located in Sichuan Province,
discovered in 1986, amaze with the diversity of ritual bronze sculpture, a large number of thin jade scepters and dagger axes, and the technology of making thin gold
foil coatings. The unusual style, clearly based on a rich mythology, is completely
unlike the synchronous cultures of adjacent territories. Many researchers, having paid attention to the unusual physiognomic characteristics of the anthropomorphic figures, have made various assumptions about the ethnicity of the people of
Sanxingdui culture and even about a possible alternative center for the emergence
of Chinese civilization in the Sichuan Basin. In 2020, six more pits were discovered—
Nos. 3–8, located next to the 1986 pits No. 1 and No. 2, many of them are stylistically
very similar to the finds of the first pits, and some demonstrate completely new
categories of ritual inventory.

The article examines the data on the life of soldiers in the northwestern
garrisons of the Han Empire based on the materials of wooden and bamboo slips
hanjians stored in the Gansu Provincial Museum and the Museum of Wooden Slips
in Lanzhou. Translations of this daily administrative documentation allow us to analyze the life and official duties of the cavalry troops qishi, soldiers serving at watchtowers, suizu, soldier-farmers tianzu, as well as the necessary criteria for entering
the service, strategies and methods for repelling nomad raids on Han territories,
the specifics of rations and salaries receiving for soldiers, officers and their families, the specifics of administrative management in the northwestern prefectures
of China at the turn of the eras.

Published: January 2025

The paper describes imported items from a tomb of the 2nd half of the
5th century AD that belonged to Li Xian and his wife (Guyuan, Ningxia, PRC). The
main versions concerning the production centres and the routes of these items to
Guyuan are presented. Particular attention is paid to a silver ewer with gilt decora‑
tion. The issues of the origin of the ewer and the semantics of its images remain con‑
troversial. Li Xian, as a highranking official and military leader, could have received
of Central Asian and Iranian items as a gift from the imperial house or directly from
trade and diplomatic missions passing through Guyuan.

The article discusses the features of the fortification of the Wandu Mountain
City, located next to ancient Guonei city near the Ji’an city, Jilin province of the China.
It was a place where at one time, the capital of Koguryo in the middle stage could
have been located. Excavations at the site at the beginning of the 21st century provide a lot of information about shape, size of the ramparts, walls construction technology, and features of defensive structures on the gate and walls. The design of
the gates with the finds are also considered, it be reconstructed as buildings with
a tiled roof. The strategic location of the Mountain City and powerful fortification
strengthened the capital region. Wandu Mountain Site was one of the typical examples of a mountain city site in Koguryo.
