FÜRUZAN’IN ÖYKÜLERİNİ SOSYAL EŞİTSİZLİK BAĞLAMINDA OKUMAK
Authors: UŞAKLI SANDAL Burcu
Published: December 2022

Cumhuriyet Dönemi kadın yazarlarımızdan biri olan Füruzan, 1950’li yıllarda edebiyat dünyasına adım atmıştır. 1970’li yıllarda kaleme aldığı eserleriyle üne kavuşmuş, uzun yıllar farklı türlerde eserler vermiş ve eserleri pek çok kez ödüle layık görülmüştür. Ancak Füruzan, edebiyatımızdaki asıl yerini öyküdeki başarısıyla elde etmiştir. Nitekim Parasız Yatılı adlı eseriyle 1972’de Sait Faik Hikâye Armağanı’na layık görülmüştür. Yazarın Parasız Yatılı ile yakaladığı başarı sonraki pek çok öyküsünde de sürdürülmektedir. Söz gelimi Kuşatma, Benim Sinemalarım, Gül Mevsimidir, Gecenin Öteki Yüzü, Sevda Dolu Bir Yaz adlı kitaplarda yayımlanan öyküler yazarın sanat hayatındaki gelişimini göstermesi bakımından dikkate değerdir. Füruzan, öykülerinde genel itibariyle küçük insanın sıradan yaşamını, özellikle kadınlar ve çocuklar üzerinden işlemiştir. Bu yönüyle onun öykülerinin kadın dünyasını içeriden bir bakışla ve samimi bir üslupla yansıttığı söylenebilir. Bunun yanı sıra yoksulluk teması ve göçmen olma hâli de yazarın öykülerinde göze çarpmaktadır. Füruzan’ın öykülerine kadın, yoksulluk ve göçmen sorunları bağlamında bakıldığında pek çok metinde sosyal eşitsizliğe vurgu yapıldığı görülür. Elbette bu durum yazarın toplumcu gerçekçi tarafıyla ilintili olarak düşünülebilir. Özellikle gelir adaletsizliğinden ve ataerkil sistemin kadına bakışından doğan birtakım problemler ile göçmen olma hâlinin öykü kişilerinin dünyasında yarattığı öteki olma hissi yazarın pek çok öyküsünde karşımıza çıkmaktadır. Bu da Füruzan’ın sosyal eşitsizliğe bilinçli bir dikkatle yaklaştığını gösterir. Buradan hareketle çalışmamızda Füruzan’ın öykülerinde öne çıkan yoksulluk, gelir adaletsizliği, ötekileştirme gibi olgular, genelde edebiyat ve sosyoloji ilişkisi özelde ise sosyal eşitsizlik bağlamlarında incelenecektir.

Speed control of an inspection projectile in low-pressure gas pipelines can be performed by changing the cross-section of the central channel when turning the flap, and it is more effective the lower the resistance to gas flow through the central channel. Peripheral bypass channels are used to reduce the resistance. We conducted analysis of gas flow in these channels with cut-outs intended to accommodate the flap turning device and brakes. A design of the channels that provides a 15% decrease in drag force is proposed (the maximum decrease in force in the design with bypasses without cut-outs is 20%). The dependence of the damper drag force on the angle of its rotation, used in controlling the movement of the inspection projectile, was also calculated. In a wide range of angles, the drag force was found to be proportional to the fraction of the overlapped area.

We propose a new physical and mathematical model for description of silicon vapor high-temperature transfer under medium vacuum conditions from the melt mirror to the surface of an absorbing porous medium in an atmosphere of residual gas. The developed model is simplified to the greatest extent possible and is intended for further numerical implementation in the course of modeling a non-stationary three-dimensional process of high-temperature siliconization of arbitrary-shaped porous carbon products under the condition of a complex distribution of silicon sources. The physical and mathematical model of transport consists of only one non-linear partial differential equation for the silicon vapor concentration in an atmosphere of argon or any other residual gas. In the limiting case of the simplest geometry and one-dimensional formulation of the problem, we obtained a stationary analytical solution that explains the anomalously large silicon vapor flux into the porous material in full-scale experiments. The obtained analytical solution for the studied gas mixtures is expressed in terms of the known verified values of the material parameters. It shows that despite the low saturation density of silicon vapor, the vapor-liquid-phase process of high-temperature siliconization of carbon materials is physically possible in a reasonable time.

Published: December 2022

This article discusses forced oscillations and parametric instability of a cylindrical drop and an ensemble of drops under circular vibrations. The drop is surrounded by an incompressible liquid of a different density and is sandwiched between two parallel plates. In equilibrium, the drop has the shape of a circular cylinder bounded in the axial direction by these plates. The dynamic and average shape of the drop is constructed. A system of amplitude equations for small perturbations of the forced oscillations is obtained and the parametric instability of the single drop is studied. By analogy, a system of equations was written to study the parametric instability for an arbitrary drop in an ensemble of interacting drops. The regions of instability are constructed both for interacting modes and for modes of a higher order. It is shown that in the case of nonzero interaction, the lower modes are more dangerous in the presence of frequency detuning.

Authors:   Institute of Ecology and Genetics of Microorganisms, Ural Branch RAS, Egorova Darya O. ,   Belgorod State National Research University
Published: December 2022

The destructor strains of polychlorinated biphenyls (PCBs) Rhodococcus ruber P25 and Microbacterium oxydans B51 decompose the main intermediates of aerobic bacterial destruction of PCBs - chlorobenzoic acids (CBC). It was found that when cultivating the M. oxydans B51 strain on biphenyl as a carbon source, colony–forming units increase by four orders of magnitude in 4 days, and when cultured on 2XBC - by three orders of magnitude in three days. The level of destruction of the substrate was 99.0–99.5%. When cultured under cometabolism conditions (CBC and biphenyl are present in the medium), the specific growth rate of M. oxydans strains B51 and R. ruber P25 increased by 1.53–1.58 times, and the destruction efficiency of 2XBC and 4XBC was 98.9–99.2%. The main metabolites of bacterial transformation of biphenyl and CBC in the medium have not been recorded, but the accumulation of chlorine ions has been established (after 5 days. the cultivation concentration was 64.98–98.05% of the maximum possible). The results obtained indicate the effective destruction of CKD by M. oxydans strains B51 and R. ruber P25 in the presence of an additional carbon source.

The article presents the results of evaluating the effect of the addition of glucose and lecithin to the culture medium (Brain Heart Infusion Broth) on the rate and accumulation of biomass of various Streptococcus pneumoniae strains: No. 3405, serotype 4 (K-4); No.16082, serotype 14 (K-14); No. 3391, unstable in capsule formation (R-form). There was an increase in the biomass accumulation of strain No. 3405 (K-4) by 10% in the variant with the addition of lecithin; an increase in biomass by 64% and an elongation of the stationary phase in strain No. 16082 (K-14) when grown with the addition of glucose. There was an increase in the biomass growth of strain No. 3391 (R-form) by 37.5% and an extended duration of the stationary phase occurred when grown with lecithin. Based on the results obtained, it can be noted that lecithin and glucose had different effects on the growth of the studied strains of pneumococcus. The obtained data showed that strain No. 16082 (K-14) was the most promising and technologically advanced. Strain No. 16082 (K-14) had a more stable growth during three passages and in all three cases was identified with a high score value (2>) by MALDI-TOF mass spectrometry, had a higher level of biomass accumulation, and possessed a denser sediment of biomass. The study resulted in the selection of strain, optimal composition of the growth medium and suitable cultivation conditions to obtain a higher yield of S. pneumoniae biomass.

The toxic effect of nanoparticles of molybdenum (VI) oxide (MoO3 NPs) after a single oral intake was studied. We administered the test substance as an aqueous suspension at a dose of 2000 mg/kg body weight. Organs were taken from surviving animals 14 days after exposure to study the bioaccumulation of MoO3 NPs and pathomorphological changes caused by the action of this nanomaterial. On the second day after exposure, the death of 50% of the group exposed to NPs was recorded. It has been established that MoO3 NPs accumulate in the heart, lungs, liver, kidneys and brain in concentrations 15.59-221.86 times higher than the control values. In the liver of exposed rats revealed by histological methods the development of hepatitis and microvesicular steatosis; in the lungs – acute bronchitis, vasculitis; in the brain – subarachnoid hemorrhage. MoO3 NPs have a more apparent ability to bioaccumulate and produce toxic effects in comparison with their microdispersed analogue under single oral introductions into the body.

The microflora of the pathological material from patients with postoperative infections was studied and the resistance of isolated strains to antimicrobial agents was analyzed. The biological properties and antibacterial sensitivity of the bacterial strains isolated during the studies was assessed according to generally accepted methods that regulate the work of a microbiological laboratory. The study included 83 patients of the abdominal oncology department who underwent surgical treatment in 2017-2021. During this period, gram-negative microflora prevailed in the pathological material (p < 0.05): Acinetobacter baumannii, Citrobacter braakii, Enterobacter asburiae, Enterobacter cloacae, Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa, Pseudomonas putida, Proteus mirabilis, Serratia liquefaciens, Stenotrophomonas maltophilia. Kl. pneumoniae, E. coli and Acinetobacter baumannii were the leading pathogens. Gram-positive microflora in 2017-2021 was represented mainly by enterococci (E. faecalis, E. faecium and E. gallinarum) and staphylococci (S. hominis, S. haemolyticus, S. sciuri, S. epidermidis, S. aureus). E. coli was one of the dominant microorganisms within the period under study. The strains of this microorganism had polyresistance to the main antimicrobial drugs (ceftazidime, ampicillin, amoxicillin/clavulanate, trimethoprim/sulfamethoxazole, ciprofloxacin). E. coli strains remained susceptible to tigecycline, meropenem, and ceftazidime/avibactam. For prevention of postoperative complications in the abdominal oncology department, it is necessary to continue microbiological monitoring, strengthen the control of gram-negative microflora (as it is expected that it will remain the leading etiological agent of postoperative infections in this department) and use tigecycline, meropenem, and ceftazidime/avibactam for the treatment and prevention of postoperative complications caused by E. coli.

The aim of the work is to study modern ecological, epizootological and epidemiological features of rabies in the Omsk region at the beginning of the 21st century, as this region is traditionally considered a rabies-prone territory. The paper describes the cases of rabies infection in human in the Omsk region in 1962–2020 and determines the features of treatment-seeking behaviour after traumatic contacts with animals in 2001–2020. The features of the epizootic process within the period 2001-2020 were studied. The number of foxes and raccoon dogs, i.e., the main natural hosts and distributors of rabies was analyzed. The epizootic index and infection density in different districts of the region for 2001-2020 were revealed. A modern epidemiological zoning was carried out and the risk of rabies incidence in different districts of the Omsk region was determined. The epizootic process of rabies in the region was determined to undergo significant changes at the beginning of the 21st century. A pronounced downward trend was revealed in the number of detected animal diseases. Epizootics form persistent foci, localized during the study period mainly in the subzone of the northern forest steppe. This previously unobserved feature of the landscape confinement of foci to the northern forest-steppe zone is apparently associated with a change in the population structure of natural hosts of the infection and a significant increase in the number of raccoon dogs. Conclusions: to optimize preventive measures, it is necessary to pay attention to the vaccination of all groups of animals involved in the epizootic process, to continue oral vaccination of wild predators. There are conditions for the formation of persistent natural foci of infection and the possibility of epizootics to get activated. This determines the relevance of constant virological monitoring of the populations of foxes, raccoon dogs, corsacs and badgers, as well as monitoring the density of populations of these species.

The geomorphological heterogeneity of the Southern Urals, the impact of air masses from the Atlantic Ocean and internal territories of the Arctic and Siberia form a significant intra- and interannual variation of temperature and precipitation in the Republic of Bashkortostan, which is a Russian region with an area of about 143 thousand square kilometres. The aim of the present study is to analyse the spatial and temporal dynamics of these two most important environmental factors in the light of the results obtained in the study of genetic differences in pedunculate oak populations. For genetic analysis, plant material was sampled in 14 natural stands of the region, 412 loci of single nucleotide polymorphisms of nuclear DNA were used. Information on the dynamics in 2004-2019 of temperatures and precipitation in the southern, central, northern and western parts of the Republic of Bashkortostan is also used in the context of months. We have shown that temperatures in all meteorological stations vary by months and years quite synchronously. The studied territories differed much more in the mode and amount of precipitation, the differences reached a statistically significant level of 59.7% (mainly in the months of the growing seasons) of monthly comparisons of pairs of the stations. At the same time, the populations of pedunculate oak have similar levels of genetic diversity and are genetically relatively weakly differentiated, which proves the system's stability to environmental factors under global climate change. It is discussed that the phenomenon revealed may be related to the effectiveness of a genetically realized pollen flow, including between remote stands.

Published: December 2022

Due to the development of information technology, many researchers have received access to the latest methods in the observation, recording, and analysis of various kinds of data arrays. Thus, machine analysis based on new algorithms facilitates the comparison of different patterns of behavior, including the study of the dynamics of animal activity under the influence of neurotropic drugs, an example of which is phenazepam. The aim of our study was to use computer analysis systems to compare the behavior patterns of two groups of laboratory rats: the control group and the group following phenazepam, as well as to study the overall effect of phenazepam on the behavior of rats. As the study showed, features were revealed in the level of expression of the general trajectories of rat movement during the testing. In addition, the use of home-developed color time coding techniques, made it possible to detect the existence of a correlation in behavior between two time positions of the same animal. The scope of the methods developed by us is not limited to scientific and laboratory practice. Some of these methods are applicable to humans, especially patients suffering from a wide range of neurological and motor disorders.

Published: December 2022

The application of a new approach to the analysis of the behavior of laboratory rats based on the color coding of the video frame sequence is presented. Behavioral features were identified in rats injected with haloperidol. In the experimental group, motor activity on the periphery of arena was significantly lower than in the control group. Moreover, there was a tendency to a significant decrease in physical activity in the second half of the test period. In the control and experimental groups, there was a pronounced difference in such patterns as moving forward, turning right, left and turning back. Among the static criteria, a significant difference in favor of the control was observed in the proportion of the following types of behavior: sniffing the air, walls or floor, examination of the arena holes, rearings with and without support. The application of the self-developed method, combining three time points in one frame: the present, the nearest and the more distant future, allowed us to establish a number of important rules. Thus, in the group that received haloperidol, the prediction of the future motor pattern based on the current position of the head and/or body of the animal turned out to be much stronger than in the control group. In addition, for animals injected with haloperidol, a pronounced stereotype of motor activity was characteristic. The combined frames were able to provide objectivity and high reliability in the most complex behavioral analysis, the dynamic patterns. In the future, this information will be required to obtain an optimal array and an acceptable variety of data for applying machine learning methods and automating the process of pattern recognition.

The search and study of new neuroprotective agents is an urgent task of biomedical research. Due to the low translational potential of the results of experimental and preclinical studies, new approaches are needed to evaluate the effectiveness of new compounds that have a positive effect on vascular or traumatic brain lesions. The method of pharmacoencephalography (pharmaco-EEG) is one of the neurophysiological research methods that allows you to assess the functional state of the brain in terms of its bioelectrical activity. Despite the need for surgical intervention, pharmaco-EEG in experimental neuroscience has several advantages over traditionally used behavioral tests, as well as biochemical or molecular genetic methods. This review considers examples of the use of this method to assess the neuroprotective activity of drugs in models of traumatic brain injury and stroke in rodents. However, based on the results of published studies, it can be concluded that pharmaco-EEG is a sensitive method for assessing the effects of drugs on the course of pathological processes in brain damage in rats and can be considered as a useful addition to traditional experimental approaches.

Pharmaco-EEG is a promising method for the study of drugs aimed at identifying their specific effect on the electrophysiological activity of the brain. This method can be used both for screening of new molecules and for detecting the still unexplored effect on the central nervous system of drugs used in clinical practice for a long time. The identification of dose-dependent effects is of particular interest in the context of studying the latter, since most of the drugs affecting the CNS can be prescribed to patients in different dosages depending on the severity or nature of the disease, which is associated either with an increase in their effectiveness or with an effect on additional targets. Since most of the psychotropic or neurotropic drugs of the first generations are non-selective and can bind to a large number of targets, a study using pharmaco-EEG can reveal both the main and side dose-dependent effects. Promethazine is a first-generation antihistamine, and in addition to the blockade of H1 receptors, its effect is also due to the blockade of M-cholinergic receptors, which is why a wide range of actions of this drug is associated. In this study, the effect of promethazine at different doses (0.5 mg/kg, 5 mg/kg and 20 mg/kg) on the amplitude-spectral characteristics of electrocorticograms in rats was evaluated, followed by analysis of the principal components. As a result, it was found that promethazine has a dose-dependent increase in the values of the main component PC1, which reflects the amplitude characteristics of electrocorticographic activity. At the same time, the effects of the drug on the spectral characteristics of the recorded signals were multidirectional and did not have statistical significance.

Published: December 2022

Because of the improvement of instrumentation and technology progress in the conducting of gravity survey, there is a continuous increase in the accuracy of calculating the gravity Bouguer anomalies. At the same time, due to inadequate assessment of the intermediate layer density taken as a constant for reduction, the calculated anomalies may contain significant relative error. The article describes the experience of using the three-point formula of V.M. Berezkin to build a map of the areal distribution of the density of the intermediate layer and calculating, on its basis, anomalies in the Bouguer reduction according to high-precision gravimetric surveys at the Gubakha area.

Published: December 2022

The technology for extracting and discharging coal from an underroof seam uses the so-called gravitational extraction method in which coal is extracted and discharged from under the roof by gravity. Here, coal can be discharged onto the main conveyor (face conveyor, located in the supported area), central conveyor (rear conveyor in Western literature), and tail conveyor (discharge conveyor, located in the unsupported area). The most common facilities used currently are longwall sets of equipment providing discharge onto tail conveyors. The purpose of this study is to measure the performance of a motorised plate feeder supplying coal from the outlet port of a roof support to a conveyor during the extraction of thick seams with discharge onto the face conveyor. To achieve the goal, it is proposed to measure the coal volume using machine vision. Methods for calculating a unit volume in a measuring section using a three-dimensional model were investigated. Laboratory studies were carried out to estimate the relative errors of the methods. The research allowed properly defining: a method for collecting data to calculate the unit volume of coal; a method for calculating the unit volume in the measuring section; a method for calculating the feeder performance using machine vision, and approaches for physically simplifying the video scene examined by machine vision. A relative error of less than 10 % with the existing measurement accuracy for constructing a coal layer surface height map indicates the sufficiency of the proposed calculation method for engineering use. The developed mathematical apparatus for calculating the unit volume of coal at the measuring section and measuring the feeder performance allows creating algorithmic software using the elementary mathematical functions of addition, subtraction, multiplication, and division. This aspect is important because it lower sights for the software development environment, and therefore expands the range of hardware suitable for calculating the feeder performance.

Published: December 2022

We suggest an elliptic curve modification of the undeniable signature introduced by D. Chaum and H. van-Antwerpen. The signature generation algorithm is supplemented with a preliminary stage of randomization. For signature verification and disavowal protocols, two options are offered. Theorems showing that these protocols meet their purpose have been proven. A method for converting an undeniable signature into a regular digital signature is described, illustrated by the Schnorr electronic signature scheme as an example.

Published: December 2022

The class of block cryptographic XSLP-algorithms called "hypercube" is considered. For algorithms of this class, we obtain estimates for the dispersion index of a linear environment for any number of iterations. It is shown that when choosing a transformation P using generalized de Bruijn graphs for the algorithms under consideration, the avalanche effect may not occur, as a result of which the encryption key can be determined with laboriousness, which is significantly less than the laboriousness of total key testing.

The generic complexity of the bounded problem of graphs clustering
Authors:   Sobolev Institute of Mathematics, Siberian Branch of the Russian Academy of Sciences, Rybalov Alexandr N.
Published: December 2022

Generic-case approach to algorithmic problems studies behavior of an algorithm on typical (almost all) inputs and ignores the rest of inputs. In this paper, we study the generic complexity of the bounded problem of graphs clustering. In this problem the structure of objects relations is presented as a graph: vertices correspond to objects, and edges connect similar objects. It is required to divide the set of objects into bounded disjoint groups (clusters) to minimize the number of connections between clusters and the number of missing links within clusters. We have constructed a subproblem of this problem, for which there is no polynomial generic algorithm provided P ≠ NP and P = BPP. To prove the theorem, we use the method of generic amplification, which allows to construct generically hard problems from the problems hard in the classical sense. The main component of this method is the cloning technique, which merges the inputs of a problem together into sufficiently large sets of equivalent inputs. Equivalence is understood in the sense that the problem for them is solved in a similar way.

Authors: Almeida Camila Couto de , Ventura Katia Sakihama
Published: December 2022

Inadequate disposal of municipal solid waste (MSW) is a common practice in some Brazilian municipalities, raising the level of economic and socio-environmental impacts. The main objective was to characterize the MSW of the municipality of Simão Dias (SE) through field visitations. The elaboration tools were a checklist, characterization sheet, and observation evaluation matrices (GUT and SWOT). Eighty-four (84) points were identified as irregular deposit spots for these materials, of which the volume estimated was around 6,150m³. A disposal period of 3 years has been considered in the visited places, and the estimated cost was approximately R$319,234 (R$2.63/hab. year) for the withdrawal of MSW at all points. Most observations (73.8%) occurred due to the accumulation of construction waste. The main challenges were the inexistence of public policies for proper MSW management, as recommended by Federal Law 12.305/2010; lack of knowledge about the origin and quantification of MSW by the local government; lack of adequate segregation at the generating source and inefficiency of actions for selective collection. Among the opportunities that stand out, the performance of the existing cooperative and the participation in an inter-municipal consortium are the most noteworthy. The main contribution of the study was the organization of information to support municipal decision-making in this sector.

Authors: Vieira Paulo Henrique
Published: December 2022

As atividades de mineração estão diretamente relacionadas com as modificações da superfície terrestre. Assim, foi selecionada como área de estudo o município de Cordeirópolis, o qual teve a paisagem intensamente modificada pela atividade minerária. Para atingir o resultado seguiu-se a seguinte abordagem metodológica: Revisão bibliográfica; Processamento dos dados; Elaboração dos mapas temáticos; e Trabalhos de Campo na área de estudo. Observou-se que as minerações provocaram diversos impactos ambientais no local: retirada da vegetação e de camadas de solo, poluição da água, solo e ar, alteração hidrológica, além de gerar transtorno no tráfego da cidade. Desta forma, a elaboração de um planejamento com atividades mitigadoras é imprescindível na instalação de indústrias cerâmicas e das atividades mineradoras

Published: December 2022

Após a Segunda Guerra Mundial, e com a crise do Petróleo na década de 1970, a iminência da questão energética fez surgir publicações e posteriormente reuniões oficiais entre nações, a fim de se debater a pauta energética, climática, econômica e social associadas. Em 2015, a Organização das Nações Unidas (ONU) instituiu a Agenda 2030, que entre as estratégias apontadas, redefiniu os Objetivos do Desenvolvimento Sustentável (ODS), na qual o Brasil aderiu. São 17 ODS e 169 metas, com cenário de atingimento até 2030. O presente artigo foi verificar o cenário atual das metas do ODS 7, o qual refere-se ao tema Energia  Limpa e Acessível, no Estado de São Paulo, Brasil. A metodologia utilizada foi revisão documental de relatórios nacionais e estaduais com informações do estado de São Paulo. Este estado possui 99,9% dos domicílios com abastecimento energético. Quanto a eficiência energética, as políticas públicas ainda não demonstram resultados satisfatórios. Já a oferta energética associada a fontes renováveis, sua participação é de 62%, estando a frente da média global e brasileira.

Published: December 2022

Introduction: Pharyngeal airway space has become an important criterion for diagnosis and treatment planning and this has led to a paradigm shift towards soft tissue evaluation for orthodontic diagnosis and treatment planning, The aims and objectives of the study were to evaluate and compare upper pharyngeal airway space in Cleft Lip & Cleft Palate patients who underwent orthodontic treatment under different treatment modalities like Camouflage treatment & Maxillary Advancement. Methods: This is a retrospective cephalometric study in which 20 Pre-treatment Cephalograms and 20 Post-treatment Cephalograms of Cleft Lip and Palate patients were taken. Orthodontic treatment involving Camouflage therapy and Maxillary Advancement were studied in each respective group. The Cephalogram was traced on Matt acetate paper and the pharyngeal airway space was measured using the McNamara analysis method. Results: Statistically significant difference was observed in the Pre-treatment and Post-treatment mean values in both groups, where the Post-treatment mean was higher than the Pre-treatment means in both groups. A highly significant mean was noted in the Cleft Surgical group as compared to the Camouflage (xiii) group, where, the post-treatment upper airway mean was higher in the Cleft Surgical group than the Cleft Camouflage group. Conclusion: There is a significant increase in upper pharyngeal airway space in patients with CLCP treated with Maxillary Advancement and Camouflage modality. The significance is comparatively more in the Maxillary Advancement group than in the Camouflage group.
Nebrija y el paradigma cultural en la educación castellana (ss. XV-XVI)
Authors: Alvar Nuño Guillermo
Published: December 2022

A menudo, se ha presentado a Antonio de Nebrija como un “debelador de la barbarie”, pero pocas veces se ha explicado en qué consistió tal barbarie. Esta contribución pretende situar la obra de Antonio de Nebrija en dos ejes. El primero, cronológico, en el que se intentará explicar en qué medida sus escritos marcaron un cambio respecto a la tradición anterior y de qué manera se deben entender su labor humanística. El segundo eje es de tipo espacial, y con él se pretende destacar cómo Nebrija fue uno de los autores –no el primero, desde luego, pero quizás sí el más importante– que cambiaron el paradigma cultural en Castilla, al abandonar la influencia que ejercía Francia y situarse bajo la de los intelectuales italianos.
Nebrija como puente entre la tradición hispánica y las gramáticas misionero-coloniales de Filipinas. Aspectos fónicos
Authors: Cuevas-Alonso Miguel
Published: December 2022

El presente trabajo analiza el tratamiento del componente fónico en dieciséis gramáticas misioneras de tradición española de las lenguas tagala, pampanga, bisaya y pangasinana (ss. XVII y XVIII). Partimos de la manera en que era concebido este fenómeno en las gramáticas de tradición grecolatina, hispánica peninsular y amerindia. Nebrija se constituye en el eje vertebrador de los recursos que los misioneros artígrafos utilizan en la descripción de las lenguas amerindias y filipinas.
En nuestro trabajo concluimos la importancia que tiene el conocimiento de la gramática latina del de Lebrija y la impronta que deja, también, su gramática castellana. Analizamos la dificultad que entrañó la descripción del componente fónico para los misioneros, especialmente en la aplicación del alfabeto latino a las lenguas que se disponían a describir. Todos ellos son conscientes de la importancia de esta cuestión desde dos perspectivas: a) la pedagógica y b) la diferenciación de significados.
