La relación Estado-educación y el proceso de reforma educacional: una aproximación desde la teoría crítica
Authors: Espinoza Óscar
Published: April 2023

El presente artículo tiene como propósito proporcionar una mirada crítica en relación a tres aspectos: a) el rol que juega y debiera jugar el Estado respecto a la educación, en general; b) la naturaleza y metas de cualquier reforma educacional, así como la retórica que las acompaña; y, c) las razones que explicarían por qué las reformas educacionales llegan a culminar exitosamente o a fracasar. Para este efecto, el documento discute inicialmente los principales supuestos teóricos que guían a la teoría crítica y a continuación discute en profundidad la postura de los teóricos críticos en relación a los temas antes mencionados.
Gestionar la escuela en Latinoamérica. Gestión educativa, realidad y política
Authors: Tello César Gerónimo
Published: April 2023

El propósito de este trabajo es analizar determinadas particularidades teóricas acerca de la “gestión educativa” en la realidad latinoamericana, por ello intentaremos desplegar el análisis desde una perspectiva crítica de la administración educativa, de la cual surge el campo de la Gestión Institucional. Al referirnos a perspectiva crítica lo hacemos situándonos en la propia realidad latinoamericana, en oposición a aquello que en este artículo denominamos realidad extraña.Para gestionar se requiere del conocimiento sensible como actitud frente a la realidad. Desde esta perspectiva toda apreciación, definición o conceptualización acerca de la gestión educativa acarrea una posición frente a la realidad, posición pedagógico-política.Por esto se requiere repensar la gestión educativa desde la propia Latinoamérica, dado que aún poseyendo elementos teóricos valiosos, no se adapta en muchos casos a la propia realidad.

Dispersion stability of tin(IV) oxide nanoparticles dispersed in N-Methy-2-Pyrrolidone (NMP), dimethylformamide (DMF) and distilled water assisted by ultrasonication was investigated, aiming to identify a suitable liquid medium to effectively disperse tin(IV) oxide for many useful applications. The dispersions’ stability was characterized using field emission scanning electron microscopy, ultraviolet–visible spectroscopy and Zeta potential. The results show that distilled water has the highest stability with optimum sonication of 1 h. NMP shows better stability and consistency than DMF at different sonication timings. Good agreement between ultraviolet–visible absorbance and Zeta potentials shows that both distilled water and NMP are good mediums to produce highly stable tin(V) oxide dispersion.

In general, the shape of the polished pattern is not flat but has a rounded curved profile. Unlike micro-patterns that have similar scales to pad asperities, macro-patterns have a very large scale compared to asperities, so bulk deformation must also be considered. To derive the pad bulk deformation, real contact area (RCA) measurements were performed in this study. Based on the preceding contact model, a semi-empirical model for RCA and bulk deformation was derived. After including the constructed pad bulk deformation function in the existing Greenwood–Williamson model, a new model that can derive the material removal rate profile according to the position in the pattern was presented. Unlike the general upper and lower removal rate behavior, this model shows a unique behavior. At the beginning of polishing, the edge shows a higher removal rate than the center, but after a specific step height, the center has a higher removal rate due to the curved shape. Analysis was performed for comparison between the proposed model equation and the experimental value. When the polishing profile in the 10 mm pattern was compared with the previous model and the proposed model, respectively, the existing model did not predict the removal rate distribution according to the position in the pattern. However, this model has the advantage of predicting both over-polishing at the edge of the pattern and high removal rate at the bottom. In addition, it was confirmed through simulation that the 4 mm and 2 mm patterns had excellent matching properties.
A binarized spiking neural network based on auto-reset LIF neurons and large signal synapses using STT-MTJs
Authors: Liu Haoyan , Ohsawa Takashi
Published: April 2023

A binarized spiking neural network using auto-reset leaky integrate-and-fire neurons with a two-transistor and three-magnetic tunnel junction core and large signal synapses with two-transistor and two-magnetic tunnel junctions is designed. The network is applied to a classifier of the MNIST handwritten digit dataset with a 784 × 400 synapse crossbar array. The weights are trained offline using the spike-timing-dependent plasticity learning algorithm and deployed to the spin-transfer torque magnetic tunnel junction (STT-MTJ) resistances in the synapses after being binarized. Its performance is evaluated by HSPICE using the STT-MTJ device model, which takes the stochastic change in the angle between the two magnetic moments in the free and pinned layers into consideration. 75% test accuracy is achieved for 1200 patterns with 1 ns read and 1 ns write operations and 0.23 pJ/SOP energy consumption.

Issues of increasing the reliability of the operation of reclamation systems, using the example of a multi-support sprinkling machine (DM) "Kuban-LK1", operating in motion in a circle, are considered in the work. It has been established that due to the increased mass of the DM structure, it becomes necessary to equip the running systems with propellers with an increased profile width. The use of a disk leveling device is proposed to eliminate the negative impact of the track from the running systems of the DM. It is noted that the Kuban-LK sprinkling machine, whose running systems are equipped with pneumatic tires of size 18.4R24, forms a track of up to 0.30 m or more. Taking into account the constant static pressure on the soil DM, the indicator of movers is justified - the bearing capacity of the soil, determined by the dependence of Professor A.I. Ryazantsev. According to exploratory studies, it was revealed that with an increase in the number of full revolutions of the machine on an irrigated surface, the values of the bearing capacity increase, on average, by 3.5 times, both with and without a leveling device installed, so it becomes necessary to install propellers with an increased specific pressure in comparison with serial samples. It was found in the course of laboratory, as well as laboratory and field tests, that when the DM "Kuban-LK1" moves, one wheel of its running system has a pressure equal to 16 kN, therefore it must be equipped with tires enlarged in profile. It has been experimentally found that the installation of propellers of the specified size reduces the power consumption of gearmotors by 25-26%, and also reduces the area of damage to agricultural products by an average of 33%.

Possible criteria for the effectiveness of inhibitor protection of agricultural machinery and equipment: integral and differential; quantitative, semi-quantitative, qualitative; a generalized quantitative assessment based on the weightiness of each type of destruction; mass, deep, volumetric; technical and economic; environmental and toxicological, etc. were considered. It was noted that each of the criteria taken separately is not always unambiguous in specific conditions, which can lead to a subjective assessment of the appropriateness of using certain corrosion inhibitors (CI). Electrochemical methods for assessing the effectiveness of inhibitor protection are highlighted as promising, which is associated with the desire of researchers to reduce the time of corrosion testing. As an example, a study of the metal-protective coating-electrolyte system by the method of polarization resistance with an assessment of the contribution of each component is considered. Compositions based on trans-former TKp, industrial I-20A, motor M10G2k, fresh and used (MMO), and combined IR CortecVpCI-368 and Cortec VpCI-369 were studied. Coatings on steel were preliminarily formed during the day. Comparison of the results on the protective effectiveness of compositions in I-20A with those also obtained by the method of polarization curves and gravimetric methods in a 0.5 M NaCl solution and in a thermal moisture chamber G-4 showed qualitatively similar results, which indicates the reliability of the results obtained by the method of polarization resistance. The maximum protective efficiency is observed for compositions based on MMO with an IC concentration of 3 -10 wt. % in MMO.

Improving the technical operation of internal combustion engines (ICE) of automotive equipment (ATT) is inextricably linked with an increase in the efficiency of their maintenance according to the actual state. The studies were carried out on internal combustion engines with resource wear of more than 80%. The method and devices for increasing the resource of the internal combustion engine ATT were proposed in this work, differing from those known in that this process is carried out in a complex way by monitoring the condition of the oil using several sensors. Lightweight and portable unit, consisting of two modules, designed for express analysis of motor oils used in internal combustion engines. Sampling from the sump-crankcase of the operated ATT (without taking it out of service) in the amount of 100 ml. is carried out with a conventional syringe with a hose, through the hole of the dipstick for controlling the oil level. Temperature sensors; contact capacitive and non-contact capacitive; turbidity; induction magnetically sensitive, pH used in the first module of the device to determine turbidity, acidity, the presence of liquid and fine metal particles, etc. Information transmitted from the sensor is displayed on the information screen of the installation, as well as on the computer monitor in the form of graphs. This installation can work autonomously, which will allow it to be used in the field. A method for adding fresh oil to the ICE lubrication system, taking into account the draining of exactly that part of the oil where the main pollutants (deposit) are located, has been developed. Timely diagnostics of the condition and quality of motor oils will allow at an early stage to assess the degree of contamination, and partial draining of the sediment at the bottom of the oil pan will prevent possible breakdowns, and thereby significantly extend the life of the internal combustion engine and ATT as a whole.

Relevance. Candida infection remains relevant due to the wide spread of antimycotic-resistant strains of Candida fungi, especially among immunocompromised individuals. It was previously discovered that the Candida spp. microbial community in the biotope of the oropharynx of HIV infected patients is characterized by a certain architecture: they can be present in this biotope in the form of a monoculture or as association of co-isolates. It has been suggested that the architecture of the Candida microbial community may influence their resistance to antimycotic drugs.
Purpose a comparative study of the association between the architecture of the C. albicans microbial community in the oropharynx of HIV infected patients with oropharyngeal candidiasis and their sensitivity to antimycotic drugs.
Materials and methods. A microbiological study of 52 isolates of Candida fungi (C. albicans, C. glabrata, C. tropicalis and C. krusei) from the oropharynx of 31 HIV infected patients with clinical manifestations of oropharyngeal candidiasis aged 20 to 69 years with almost equal gender distribution was carried out. In the form of monocultures, 18 isolates were isolated, while 34 were identified as co-isolates, which formed 16 homogeneous communities that included strains of the same species, and 18 heterogeneous ones that consisted of fungi of various species.
Results. It was found that heterogeneous communities of C. albicans were markedly distinguished by sensitivity to antimycotic drugs, in particular, by low sensitivity to imidazoles. Homogeneous communities practically did not differ from monocultural ones. The general properties of the C. non-albicans population were largely similar to those of C. albicans, but were characterized by lower heterogeneity in response to antimycotic drugs.
Conclusion. The architecture of the community of C. albicans isolated from the oropharynx of HIV infected patients with clinical manifestations of oropharyngeal candidiasis affects their sensitivity to antimycotic drugs. When selecting effective antimycotic therapy for such patients, it is necessary to take into account the structure of the Candida spp. community in the oropharynx.

Pulmonary Tuberculosis is most common diseases in India with significant mortality and morbidity. Tuberculosis can cause diverse thoracic presentations ranging from nodules, consolidations & cavitation, mediastinal adenopathy, pleural effusion to diffuse endobronchial disease presenting like bronchial asthma. In this case report, 29- year male, presented with constitutional symptoms for 4 months duration with partial response to medical treatment received according to their knowledge and experience towards bronchial asthma, enteric fever and jaundice. Radiological investigations documented only prominent hilum left side of thorax which was underestimated due to presence of wheeze. Recurrent, progressive and partially responding constitutional symptoms was the reason for referral to our center. We have also noted prominent hilum with inhomogeneous infiltrates left lung field and localized wheeze and crepitations on left side of thoracic cavity in mammary and interscapular region. We have further evaluated with HRCT thorax and observed thick-walled cavities in left upper lobe posterior segment. ‘Stepladder Lung Cavities’ in HRCT is defined as multiple cavities adjacent with each other partially communicating to noncommunicating of variable size and shape unilaterally or bilaterally in stepladder fashion. ‘Starry sky pattern’ in HRCT Thorax is defined as randomly placed nodular opacities presenting as discrete or conglomerated, interstitial and acinonodular opacities unilateral or bilateral adjacent to pulmonary cavities usually reported as satellite nodules. Satellite nodules are defined as nodular opacities adjacent to pulmonary primary caviatary lung disease and indicator lymphatic local spread and active pulmonary tuberculosis. We have done sputum examination and documented acid-fast bacilli in sputum smear and MTB genome with rifampicin sensitivity in cartridge based nucleic acid amplification test. Treatment initiated with anti-tuberculosis (ATT) and recorded near complete radiological resolution, bacteriological cure after six months with good compliance. High index of suspicion is must while managing these cases with constitutional symptoms with typical ‘Stepladder Lung Cavities’ with ‘starry sky pattern’ in HRCT Thorax to have successful treatment outcome.

"In this work, we show that a slight change in the Sklar's formula tremendously affects the class of aggregation functions it represents. While the original formula can only be used to construct $d$-increasing aggregation functions, this new formula can be used to construct any continuous aggregation function excepted possibly those belong to the boundary of this set. In particular, all continuous aggregation functions can be approximated by aggregation functions in this form. This shows that it is sufficient to only consider aggregation functions in this form for most cases. Construction examples via this method are also given."

Given a set of vertex-norm, or distances from the origin, in two-dimensional space, there does not always exist a convex configuration, or convex polygon, whose vertices satisfy the vertex-norm. In this research, we provide the necessary and sufficient conditions, based on the angles spanned by the polygon around the origin, for the existence of such convex configuration. General strategies for constructing a convex configuration satisfying a given vertex-norm set as well as examples of vertex-norm sets for which no such convex configuration exists are also illustrated.

The new capabilities that JWST offers in the near- and mid-infrared (IR) are used to investigate in unprecedented detail the nature of optical/near-IR-faint, mid-IR-bright sources, with HST-dark galaxies among them. We gather JWST data from the CEERS survey in the Extended Groth Strip, jointly with HST data, and analyze spatially resolved optical-to-mid-IR spectral energy distributions to estimate photometric redshifts in two dimensions and stellar population properties on a pixel-by-pixel basis for red galaxies detected by NIRCam. We select 138 galaxies with F150W − F356W > 1.5 mag and F356W < 27.5 mag. The nature of these sources is threefold: (1) 71% are dusty star-forming galaxies (SFGs) at 2 < z < 6 with

and a variety of specific SFRs (<1 to >100 Gyr−1); (2) 18% are quiescent/dormant (i.e., subject to reignition/rejuvenation) galaxies (QGs) at 3 < z < 5, with

Large attenuations in SFGs, 2 < A(V) < 5 mag, are found within 1.5 times the effective radius, approximately 2 kpc, while QGs present A(V) ∼ 0.2 mag. Our SED-fitting technique reproduces the expected dust emission luminosities of IR-bright and submillimeter galaxies.

The Chocolate Chip Cookie Model: Dust-to-metal Ratio of H ii Regions

Using a sample of face-on star-forming galaxies selected from the Sloan Digital Sky Survey, we statistically derive the typical optical depth τ
cl of individual H ii regions based on the “Chocolate Chip Cookie” model of Lu et al. (2022). By binning galaxies into stellar mass and gas-phase metallicity bins and interpreting τ
cl as the dust-to-gas ratio (DGR) of H ii regions, we further investigate the correlations between DGR and stellar mass and between DGR and gas-phase metallicity, respectively. We find that DGR increases monotonically with the stellar mass of galaxies. At a given stellar mass, DGR shows a linear correlation with the gas-phase metallicity, which implies a constant dust-to-metal ratio (DTM) of galaxies at a given stellar mass. These results adequately indicate that the DTM of galaxies is simply a function of their stellar masses. In terms of gas-phase metallicity, because of the mass–metallicity relation, DTM increases with increasing metallicity with a power-law index 1.45 in the low-metallicity region, while it remains constant at the high-metallicity end.
Saturn's Seismic Rotation Revisited
Authors: Mankovich Christopher R. , Dewberry Janosz W. , Fuller Jim
Published: April 2023

Normal mode seismology is a promising means of measuring rotation in gas giant interiors, and ring seismology presents a singular opportunity to do so at Saturn. We calculate Saturn’s normal modes of oscillation and zonal gravity field, using nonperturbative methods for normal modes in the rigidly rotating approximation, and perturbative methods for the shifts that Saturn’s deep winds induce in the mode frequencies and zonal gravity harmonics. The latter are calculated by solving the thermogravitational wind equation in an oblate geometry. Comparing many such models to gravity data and the frequencies of ring patterns excited by Saturn’s normal modes, we use statistical methods to estimate that Saturn’s cloud-level winds extend inward along cylinders before decaying at a depth 0.125–0.138 times Saturn’s equatorial radius, or 7530–8320 km, consistent with analyses of Cassini’s gravity and magnetic field data. The seismology is especially useful for pinning down Saturn’s poorly constrained deep rotation period, which we estimate at 2π/ΩS = 634.7 minutes (median) with a 5/95% quantile range of 633.8–635.5 minutes. Outstanding residuals in mode frequencies at low angular degree suggest a more complicated deep interior than has been considered to date. Smaller but still significant residuals at high angular degrees also show that our picture for the thermal, composition, and/or rotation profile in Saturn’s envelope is not yet complete.
A Histologic Study of Imatinib Cardiotoxicity in Adult Male Rats
Authors: Al-Allaf Luma , Alnuaeimy Wahda
Published: April 2023

BACKGROUND: Cardiotoxicity is an unanticipated adverse effect associated with some chemotherapeutic agents. There are conflicting results about imatinib-induced cardiac toxicity.
AIM: This study aims at investigating the possible cardiotoxic effects of imatinib in rat model through assessing the possible histopathological alterations that might develop.
MATERIALS AND METHODS: This is a case–control and experimental study conducted over a period of 3 months at laboratory of postgraduate studies, Department of Anatomy, College of Medicine, University of Mosul, Mosul, Northern Iraq. Sixteen adult male Albino rats were randomly assigned to either “control group” or “imatinib-treated group.” The control group was gavaged with distilled water daily for 4 weeks while the second group was given oral imatinib (200 mg/kg/day) for the same duration. Animals were sacrificed by euthanization after 24 h of the last dose. Hearts were obtained and cardiac specimens were immersed in paraffin. Sections’ staining by hematoxylin (Harris)-eosin (H&E) and Massons’ Thrichrom.
RESULTS: Rats treated with imatinib showed decreased physical activity and food intake. Regular arrangements of myofilaments were noticed during light microscopic examination of cardiac sections of control rats. However, sections from imatinib group showed several histological alterations (mainly myofibrillar loss in myocardium with vacuolated cytoplasm). Necrosis of cardiac muscle fibers was also noticed in some sections. Appearance of deeply staining cells with pyknotic nucleus, in addition to shrinkage of cardiac muscle fibers, was also noticed in some sections. The mean score of cardiac injury in the treated group was 2.1 (vs. 0.6 in controls). Some sections of treated group showed an increment (mild) in collagen fibers in-between cardiac myocytes.
CONCLUSIONS: The observations concluded that imatinib has targeted action on cardiomyocytes. Oncologists should be cautious regarding imatinib dose and duration besides the close cardiac monitoring throughout and beyond therapy duration.

The speech signal that is received in real-time has background noise and reverberations, which have an impact on the quality of speech. Therefore, it is crucial to reduce or eliminate the noise and increase the intelligibility and quality of speech signals. In this study, a proposed method that is the most effective and challenging in a low SNR environment for three types of noise are removed, including washing machine, traffic noise, and electric fan noise, and clean speech is recovered. with three samples of noise which are mixed and added to the clean speech signal with a lower level of SNR value fixed at (-5, 0, 5) dBs, that noise source takes equal weights. The enhancement of the corrupted speech signal is done by applying a fully connected and convolutional neural network-based denoising algorithm and comparing their performance. The proposed network shows that a fully connected network (FCN) has less elapsed time than a convolutional network (CNN) while still achieving better performance, demonstrating its applicability for an embedded system. Also, the results obtained show that, overall, the CNN is better than the FCN regarding maximum coloration, PSNR, MES, and STOI.

Watermarking is widely used in multimedia preservation and communication, which comprises, and is therefore not limited to, data security and validation. Security, readability, imperceptibility, and resilience are some of the key advantages of this technology. However, there are still certain issues that need to be addressed, such as the ability to withstand a variety of assaults without substantially affecting the quality and value of embedded data. Based on its operational domain, the watermarking technology may be divided into two groups: spatial and frequency watermarking. An index mapping-based watermarking approach for copyright protection of multi-media color videos is presented in this paper. We offer a hybrid discrete wavelet transform and discrete cosine transform (DCT) watermarking algorithm for digital video watermarking of a color video watermark. Peak signal to noise ratio (PSNR), similarity structure index measure (SSIM), have been used to analyze the distortion produced by watermarking. It is suggested that the proposed video watermarking method provides greater imperceptibility in conjunction with each other with the human visual system and it offers higher robustness against different attacks.
