Diversidad y alteraciones sensoriales en el cómic
Authors: Del-Rey-Cabero Enrique
Published: January 2023

Partiendo de una concepción del cómic que se aleja de su tradicional definición monosensorial en favor de un acercamiento multisensorial, el objetivo de este artículo es examinar la capacidad del medio para representar la diversidad y los trastornos sensoriales, centrándose para ello en el ejemplo paradigmático de Diagnósticos (2013), de Diego Agrimbau y Lucas Varela. Este volumen de historias cortas independientes conectadas por la presencia de distintas alteraciones sensoriales hace uso de algunos recursos formales del cómic (como la visión holística o los diferentes grados de integración de texto e imagen) para ofrecer el punto de vista subjetivo interior de sus protagonistas, todas mujeres. La obra se analiza a luz de la medicina gráfica, aunque, pese a lo que sugiere su título, se trata de un cómic de ficción que no pretende ser un manual médico. Se examinan, pues, la potencialidad del cómic de ficción con representaciones estereotipadas para generar empatía y otros aspectos relacionados con la diversidad funcional como la identidad y el género. Se concluye así que, a pesar de algunas figuraciones estereotipadas, Diagnósticos constituye un ejemplo único de la representación de la diversidad sensorial en el cómic por su carácter experimental y autoconsciente.
El cómic como lectura crítica de la historia en la construcción de la identidad y la diversidad territorial
Authors: Falguera-Garcia Enric , Selfa-Sastres Moisés
Published: January 2023

El presente artículo se aproxima a un género poco estudiado en el ámbito académico como es el cómic y en particular el cómic histórico, es decir, el que utiliza la historia con mayúsculas como telón de fondo para explicar y difundir ideas. Observamos como las características del cómic favorecen la divulgación de conceptos como el de memoria histórica y es una herramienta idónea para establecer una ideología. En el caso que nos ocupa tratamos el cómic en lengua catalana que versa sobre la historia medieval de Catalunya con los objetivos de comprobar, por un lado, la intencionalidad ideológica que se esconde tras la narración y selección de unos hechos y unos personajes concretos de la historia catalana para divulgar una determinada idea de construcción territorial e identitaria; y. por el otro, proponer un modelo de análisis del cómic tanto desde el punto de vista literario, de las estructuras narrativas, como desde el punto de vista visual.
Apperception and Related Matters in Kant’s Critique of Pure Reason and Opus Postumum
Authors: Brook Andrew
Published: January 2023

In the Critique of Pure Reason (1781/7), Kant laid out a deep-running and largely original picture of the apperceptive mind, including a claim that in consciousness of self, one does not appear to oneself as an object and that consciousness of self is presupposed by consciousness of other things. As a result, consciousness of oneself does not provide knowledge of oneself and the referential apparatus of consciousness of self is radically different from other kinds of referential apparatus. The main purpose of this paper is to summarize this picture and then explore how much of it is still to be found in his late, unfinished Opus Postumum (1800/04).
A influência ideológica da ditadura militar na reforma da educação (1964-1971): uma análise da educação moral e cívica sob o aspecto da violência simbólica
Authors: Junior Antonyo Leal , Estrada Adrian Alvarez
Published: January 2023

O artigo “A influência ideológica da ditadura militar na reforma da educação: uma análise sob o aspecto da violência simbólica”, tem o objetivo de analisar como a influência ideológica do regime, na reformulação normativa do sistema educacional no período entre 1964 a 1971, em especial na disciplina de Educação Moral e Cívica (E.M.C.), com subsídio teórico de Pierre Bourdieu, sedimentada no construtivismo estruturalista, que se pauta na análise das relações sociais mediante o que considera como campo, habitus e violência simbólica. O objetivo de trabalhar com a ideia da violência simbólica é para demonstrar como grupos dominantes se sobrepõem aos dominados. Constatou-se que as reformas no sistema educacional foram realizadas, em razão da segurança nacional, para estancar a ameaça comunista no país, para estruturar o desenvolvimento econômico nacional utilizando-se como um dos meios opressores – além da repressão e tortura – o ambiente escolar cuja característica da disciplina de E.M.C serve para que as pessoas, desde a tenra idade, agissem de acordo com o que se esperava em relação ao patriotismo, à nacionalidade, ao espírito religioso e ao sentimento de união, com o intuito de absorver as contradições sociais e contribuir para a constituição de um Estado soberano.
Vozes da rua ressoam na educação: narrativas de estudantes da EJA que vivem em situação de rua
Authors: DORNELAS DE SOUZA KLEYNE CRISTINA , Vieira Maria Clarisse
Published: January 2023

O artigo apresenta a análise das narrativas de estudantes da educação de jovens e adultos (EJA) em situação de rua e de como a educação pode promover transformações em suas vidas. O estudo foi desenvolvido em escola de natureza especial da capital do Brasil que atende pessoas em situação de rua. A metodologia aplicada foi a pesquisa qualitativa por meio da entrevista narrativa em um grupo de vinte educandos. Os estudantes tiveram voz e visibilidade a partir da análise de narrativas fotográficas. A fotografia teve o intuito de criar oportunidades para esses sujeitos narrarem suas histórias de vida a partir de uma ação protagonista de forma a apresentar o olhar desses sujeitos sobre si, sobre o grupo, sobre a rua e sobre a educação.Os textos narrativos das entrevistas foram explorados por meio do software de análise lexical chamado Iramuteq. Utilizou-se dois recursos oferecidos pela tecnologia do software: o primeiro foi a nuvem de palavras, que por meio da frequência possibilitou identificação das palavras-chave e permitiu a definição das categorias, o segundo foi a análise de similitude, que apresentou as coocorrências entre as palavras e as conexões estabelecidas entre elas. O software mostrou-se útil e eficaz para apoiar a análise das narrativas dos educandos da EJA em situação de rua. Como resultado da análise, apresenta-se indicios de que a compreensão de que a EJA pode ser um lócus potencial para um projeto de transformação na vida desses sujeitos, considerando o diálogo como atitude essencial na relação entre educadores e educandos na construção de uma educação libertadora, humanista e ao mesmo tempo conscientizadora.
Educação de Surdos na pandemia: a lógica contábil do sacrifício
Authors: Kraemer Graciele Marjana , Zilio Virgínia Maria
Published: January 2023

O trabalho tensiona as condições da educação de surdos no contexto da pandemia de Covid-19. Foram analisados 45 questionários respondidos por professores que atuam na educação de surdos. As análises partem dos Estudos Surdos e dos estudos de François Dubet. Com a suspensão das aulas presenciais, a educação de surdos acaba não promovendo a cidadania linguística. Isso resulta em ações educacionais paliativas, que não contemplam a educação bilíngue para surdos. Assim, desenvolve-se uma lógica contábil do sacrifício, pela qual apenas uma pequena parcela de alunos surdos que apresentam condições de participação tem efetivado o direito educacional.

Oil palm plantation on peatlands is considered to contribute to increasing global warming by releasing CO2 as one of the greenhouse gases that cause global warming. The addition of ameliorants, such as biochar and zeolite, can absorb CO2 from soil respiration and store and filter it in their molecular pores. This research aimed to study the effect of ameliorant application on the CO2 flux, water content, microbial population, and enzyme activities. Ameliorant was applied to peat soil with two factors. The first factor was an ameliorant combination with 6 treatment levels: control (A0); zeolite (A1); biochar (A2); zeolite:biochar 75:25; zeolite:biochar 25:75; zeolite:biochar 50:50, and the second factor was 3 levels dose of treatment (% w/w): 1.5%, 3%, and 4.5%. Peat flux CO2 and water content were measured monthly for four months in the laboratory. Without mixing with biochar (A1), the results showed that zeolite suppressed CO2 flux and suppressed the decrease of water content better than other ameliorant combinations. However, different ameliorant dosage percentages did not show any significant results. Ameliorant application and incubation affected the microbial population and enzyme activities, and the results were varied. Chemical characteristics changed after 4 months of incubation. In conclusion, our results indicate that only zeolite amendment can suppress CO2 flux and decrease water content but did not affect microbial population dynamics and enzyme activities.

Nutrition Value and Phytochemical Screening of Gembolo (Dioscorea bulbifera L.) Bulbils and Tubers from Bogor, West Java
Authors: Kuncari Emma Sri
Published: January 2023

Gembolo is often cultivated in tropical areas, mainly for its bulbils (edible aerial bulbs) and tubers. This study will discuss the nutritional value and phytochemical screening of gembolo bulbils and tubers from Bogor, West Java. There is still little information and publication about this gembolo bulbils and tubers. In addition, to reintroduce and preserve this rare plant. The research was done by exploration, direct observation, and interview, followed by laboratory analysis and literature. The methods used in the proximate analysis include moisture content (AOAC), ash content (gravimetric), fat content (soxhlet), protein content (Kjeldahl), fibre (gravimetry), and carbohydrates as starch (titrimetry). Phytochemical screening was carried out qualitatively. The proximate test results showed that bulbils had higher water, fat, and fibre content than bottom tubers. Bottom tubers have higher ash, protein, and carbohydrates as starch content than bulbils. This confirms the assumption that bottom tubers are more recommended as a source of food than bulbils and because of their larger size than bulbils. The results of phytochemical screening showed that both bulbils and gembolo bottom tubers contained the same chemical compounds, namely alkaloids, saponins, tannins, phenolics, flavonoids, triterpenoids, and glycosides.

Kefir is made from a kefir seed starter consisting of L kefiri, genus Leuconostoc, Lactococcus, and Acetobacter that grow side by side. The addition of butterfly pea flowers extract to kefir can improve functional properties and sensory. The aim of this study was to investigate the physical characteristic, chemical characteristics, microorganisms, antioxidant activity, and organoleptic properties of cow’s milk kefir with the addition of butterfly pea flowers during storage at refrigerator temperature (1‒4°C). The research analysis used a completely randomized design with a 3x3 factorial pattern with three repetitions. The first factor was the addition of butterfly pea flowers (0%, 3%, and 6%), and the second factor was storage time (0, 3, and 6 days). The physical, chemical, antioxidant activity, and microorganism characteristics were tested using two-factor ANOVA and further tested by the Duncan test. Data on organoleptic properties were analyzed by the nonparametric Kruskal-Wallis and then verified using the Mann-Whitney test. The results showed that during storage the kefir increased the pH value and TAT value and decreased the viscosity and fat content. The inhibition of DPPH and the antioxidant capacity of the addition of butterfly pea flowers extract increased and decreased with the length of storage. Lactic acid bacteria (LAB) and the yeast did not change. Sensory hedonic test panelists prefer the color and aroma of kefir with the addition of telang flower extract. Sensory test of hedonic quality with the best characteristics, namely the addition of 6% butterfly pea flowers extract.

This study aims to calculate the amount of carbon lost and the amount of oxygen that can no longer be produced by the Cogreg Experimental Garden (KPC) due to the harvesting of Nusantara Unggul Teak wood (JUN). Carbon stock loss was measured using the allometric equation method based on the SNI 7724:2011. Calculating the loss of oxygen-producing potential used the comparison method of the atomic weights of carbon and oxygen. The results of this study indicate that the harvesting of JUN at KPC causes a loss of potential carbon storage reserves of 215.384 tons/year or equivalent to IDR7.2 bilions; the loss of oxygen-producing potential is 574,359 tons/year or equivalent to IDR2.66 billions. Meanwhile, the results of harvesting JUN wood can only produce a financial value of IDR1,36 billions. Therefore, the financial value of the KPC's environmental services in the form of carbon storage and oxygen production is much greater than the financial value of harvesting JUN's wood.   Keywords: carbon loss, Cogreg Experimental Garden, Jati Unggul Nusantara, oxygen loss

This study aims to analyze potential risks and risk mitigation in the company's supply chain to minimize the company's potential losses and develop a policy strategy for importing feeder cattle during the COVID-19 pandemic as a framework (blueprint) for company readiness in the future as well as in handling food security, especially to meet the domestic demand for beef, which is currently only able to meet 70% of the total demand. In the early stages of the research, the House of Risk (HOR) method is employed to identify risk variables (risk events and risk agents) and risk mitigation. The results obtained from the risk analysis are used to develop corporate policy strategies. The results of the ANP-BOCR analysis show that the policy strategy that is set as the highest priority is the improvement and enhancement of operation and production processes (PPOP). The alternative policy strategy with the lowest priority is implementing a Go-Public (KGP) policy. Improvement and enhancement of operation and production processes carried out in the company include: 1) application of complete feed; 2) production efficiency and mechanization; and 3) implementation of Internet of Things (IoT) and Digitalization. The results of the Rater Agreement (W) show that all respondents (experts) have a fairly high agreement on the priority of the policy strategy set, with Kendall's W coefficient value of 0.5.

The article presents a debridement method of congenital cholesteatoma of the tympanic cavity, typically located in the anterior part of the mesotympanum. In this method, the meatotympanic flap is formed by separating the skin of the external auditory canal from 8 to 4 hours. Next, the tympanic cavity is opened, the tympanic membrane is separated from the handle of the malleus, starting from its short process, from top to bottom, maintaining contact in the umbo area. Then, the anterior malleus fold is dissected with a microneedle, the anterior-upper part of the bone tympanic ring is removed with a burr until the congenital cholesteatoma is fully visualized. After that, the capsule of congenital cholesteatoma is separated from the medial surface of the tympanic membrane, after which it is removed. This method allows reducing the risk of developing residual and recurrent cholesteatoma and at the same time preserving the anatomical integrity of the structures of the middle ear and the patient’s hearing.

The task of treating any disease is to improve the quality of human life. However, there is no widespread practice in clinical studies to assess the health-related quality of life before and after medical intervention. The aim of the study was to evaluate the health-related quality of life in patients with bilateral laryngeal paralysis and the impact on the quality of life of methods of therapeutic rehabilitation of respiratory function using the international standardized questionnaire SF-36 (Russian version developed and recommended by the Multinational Center for Quality of Life Research (MCQLR)). A survey of 44 patients with bilateral laryngeal paralysis after a strumectomy lasting more than 1 year was conducted twice. The first questionnaire was conducted before the rehabilitation of respiratory function, the second questionnaire was conducted 4–6 months after rehabilitation. The patients underwent rehabilitation as part of two groups: in group 1, respiratory function rehabilitation was carried out by the method of prolonged injectable relaxation of the cricoid muscle with botulinum toxin type A. In group 2, respiratory function rehabilitation was carried out with phonopedic correction by the development of respiratory techniques and drug sedation with benzodiazepine. According to the results obtained, prolonged relaxation of the cricoid muscle by a single injection of botulinum toxin type A into the thickness of the cricoid muscle improves the physical component of the quality of life associated with health by 36%, the mental component, by 50%. Phonopedic correction will improve the physical component of the quality of life by 6%, and the mental component, by 4%. The obtained result can be used in communication between the patient and the doctor at the stage of explaining the effectiveness of available methods of conservative treatment for laryngeal paralysis.

The study involved 73 patients with snoring and sleep apnea, aged 25 to 74 years, who underwent reconstructive interventions on the soft palate as a surgical treatment. As part of the preoperative examination, all patients underwent night respiratory monitoring in order to identify and assess the severity of respiratory disorders during sleep. A histological analysis of all tissues removed during the operation and a comparison of the identified changes with the visual picture during a pharyngoscopic examination were carried out. Depending on the pharyngoscopy, 5 main types of soft palate were identified, on the basis of which the patients were divided into 5 groups. The mildest clinical manifestations of obstructive sleep apnea (OSA) were noted in patients from groups 1 and 2, and the most severe, in patients from group 4. Morphological changes were represented by reactive phenomena of the mucous membrane, stromal edema, transformation of the mucous glands, an increase in the vascular component, and the development of chronic inflammation. Analyzing the results obtained, a relationship was noted between the severity of OSA and the morphological features of the removed palatine uvula. It can be assumed that 5 types of soft palate are the stages of one pathophysiological process successively replacing one another.

Objective. Evaluation of the effectiveness and safety of the use of electromagnetic computer navigation in endoscopic surgery of benign fibro-osseous mass of the paranasal sinuses and skull base. Materials and methods. The retrospective study included 21 patients who underwent endoscopic removal of fibro-osseous mass of paranasal sinuses and skull base at the Burdenko Center from 2010 to 2021. The patients were divided into 2 groups: the 1st group included 10 patients with the use of electromagnetic navigation intraoperatively, the 2nd group included 11 patients who were treated without the use of navigation. Median follow-up was 24 months [IQR 12,00, 48,00]. Results. Most often, patients complained of headache (15; 71,4%). In 14 (66,7%) cases, the ethmoid labyrinth was involved; in 11 (52,3%) cases, the sphenoid sinus; in 15 (71,4%) cases, the base of the skull, with intracranial distribution in 5 (23,8%) cases; and in 8 (38%) cases, the wall of the orbit. Surgical treatment was performed radically in 10 (47,6%) patients. The median intraoperative blood loss was 100.00 mL. Intraoperative complications occurred in 3 (14,3%) patients; postoperative complications, in 2 (9,5%) patients. Pathology recurrence occurred in 4 (19,0%) patients, more often in young people (median age 19,50, р = 0,179). The median duration of hospital stay was 3,00 bed-days. It was found that the localization of pathology in the sphenoid sinus is associated with an increased risk of nonradical removal of the formation (р = 0.009). Factors that could influence the choice of the surgeon in favor of intraoperative navigation include visual impairment in the clinical picture of the disease (p = 0,090) or the absence of difficulty in nasal breathing (p = 0.024); localization of the mass only in the sphenoid sinus (p = 0,063) or with involvement of the base of the skull (p = 0.149). The use of intraoperative navigation slightly increases the radicalness of surgical treatment and reduces the incidence of perioperative complications.

Актуальность. Статья посвящена проблеме потерь нефти и нефтепродуктов при эксплуатации резервуарных парков, наличие которых затрагивает экономические и экологические аспекты рационального использования ресурсов. Для сокращения выбросов углеводородов на предприятиях на данный момент используют различные технологические средства. Достигнутый эффект от применения существующих и разрабатывающихся способов по борьбе с потерями определяется использованием специализированных методик, которые являются несовершенными. Поэтому возможность достоверной оценки способов сокращения потерь является одной из основных задач при эксплуатации резервуарных парков и правильного выбора использования технологических средств их оснастки для установления действительно достигаемых выбросов. Цель: определить эффективность сокращения выбросов путем хранения нефти под избыточным давлением как действенного способа. Объект: резервуар вертикальный стальной номинальным объемом 10000 м3, конструкция которого способна выдерживать различные нагрузки, и дыхательная арматура с возможностью настройки на широкий диапазон давлений, в том числе значительно превышающий расчетный интервал давлений для реальных резервуаров вертикальных стальных, установленных на данный момент. Методы: идеально-газовое приближение в рамках термодинамического подхода. Результаты. Описаны результаты проведенного авторами исследования, указывающие, что настройка дыхательных клапанов на большее избыточное давление срабатывания приводит к более сложной зависимости потерь от производимых дыханий в резервуаре, т. е. потери от «малых» дыханий могут не иметь прямой корреляции с увеличением давления срабатывания клапана. Установлено, что при теоретически высоких давлениях срабатывания дыхательной арматуры в диапазоне от 9,13 до 670,88 кПа может наблюдаться рост потерь от производимых «малых» дыханий в 7,25 раз, что указывает на необходимость новых технологий и способов, способных исключить выбросы паровоздушной смеси.

Мороз // Известия Томского политехнического университета. Инжиниринг георесурсов. – 2023. – Т. 334. – № 1. – С.165-176.

Актуальность исследования состоит в необходимости поиска дешевых источников урана вблизи потенциальных урановорудных зон Северного Казахстана на основе изучения современных процессов миграции и накопления урана. Цель: построение геохимической модели выщелачивания, миграции и накопления урана в русле реки Семизбай на основе определения состава воды и донных отложений в речных и озерных резервуарах, а также состава гранитов Жаман-Койтасского массива и коры выветривания как коренного источника урана при его выщелачивании. Объекты: современная кора выветривания по лейкогранитам восточной части Жаман-Койтасского массива; русловые отложения рек Семизбай и его притока Шат; прирусловые ключевые, речные и озерные воды рек Семизбай, Селеты и озера Жамантуз; донные отложения озера Жамантуз. Методы: рентгенофлуоресцентный анализ, масс-спектрометрия с индуктивно связанной плазмой, рентгеноструктурный анализ, классические методы определения катионно-анионного состава воды. Результаты. Определены высокие содержания урана в ключевых прирусловых водах (0,32 мг/л) и водах водохранилища (0,047 мг/л), а также повышенные содержания урана в прирусловых почвах (8,6–13 г/т) и донных отложениях водохранилища (23–24 г/т) в верхнем течении реки Семизбай. На основании полученных данных предложена модель выщелачивания урана из лейкогранитов Жаман-Койтасского массива, его миграции и накопления в русле реки Семизбай, современные фации которой являются геохимическим барьером на пути распространения урана в экосистему Ишимской степи. Концентрация урана в русловых отложениях нижнего течения реки (1,9–2,7 г/т), в воде (0,0029 мг/л) и донных отложениях (4,6 г/т) озера Жамантуз, являющегося конечным сточным водоемом для реки Семизбай, отвечает фоновым содержаниям урана, характерным для Западной Сибири.

Типизация терригенных пород-коллекторов с применением метода накопленной корреляции и индивидуальных вероятностных моделей на примере месторождения Им. Сухарева // Известия Томского политехнического университета. Инжиниринг георесурсов. – 2023. – Т. 334. – № 1. – С.75-83.

Актуальность исследования обусловлена необходимостью совершенствования методов типизации пород-коллекторов при интерпретации петрофизических данных, полученных в лабораторных условиях. Типизация пород-коллекторов по структуре порового пространства является важным этапом в интерпретации петрофизических данных, полученных в лабораторных условиях, но по сложившейся практике осуществляется лишь экспертным методом, основываясь на литологическом описании образцов керна, и по зависимостям газопроницаемости от пористости. Цель: апробация метода накопленной корреляции и индивидуальных вероятностных моделей в комплексе с данными фациального анализа для типизации терригенных пород-коллекторов по структуре порового пространства. Объект: образцы керна из пяти скважин месторождения им. Сухарева, представленные отложениями тульского горизонта визейского яруса нижнего карбона. При проведении исследований использовалось 165 образцов керна диаметром и длиной 30 мм. Методы: современные методы изучения фильтрационно-емкостных и литолого-петрографических свойств, методы математической статистики для анализа экспериментальных исследований. Результаты. Показано, что при помощи индивидуальных вероятностных моделей, построенных как функции от коэффициента открытой пористости и учитывающих информацию о типе поровой структуры, литологии и фации, можно охарактеризовать изменения углов наклона и другие эффекты, выявленные на графиках накопленной корреляции во всем диапазоне расчетов. Также впервые установлено, что применение метода накопленной корреляции в комплексе с индивидуальными вероятностными моделями и данными фациального анализа позволяет с достаточно высокой степенью достоверности типизировать терригенные породы-коллекторы по структуре порового пространства. На основе проведенного линейного дискриминантного анализа была решена практическая задача разделения по типам коллектора для объекта С1tlтер месторождения им. Сухарева. Полученные результаты показывают, что использование принципа зональности при выделении коллекторов позволяет с высокой степенью точности подобрать коллекцию образцов для фильтрационных исследований, которые будут наиболее корректно отражать физико-гидродинамическую картину пласта.

Актуальность исследований обусловлена важностью проблемы рационального использования природных ресурсов в производстве композиционных строительных материалов. Возможность заменить природное сырье: известняк, глину, песок, при производстве цементных вяжущих, бетонов и растворов отходами производства позволит существенно снизить нагрузку на сырьевую базу. Серьезную экологическую проблему для горнодобывающих предприятий составляет утилизация отходов камнедробления. Применение неорганических отходов различного химического состава позволяет направленно регулировать процессы структурообразования и твердения наполненных цементных систем и получать композиционные материалы с высокими показателями физико-механических свойств. Цель: научно обосновать и исследовать возможность применения отходов горнодобывающих предприятий в качестве компонента для производства модифицирующих добавок в цементные системы. Объекты: модифицированный цементный камень; модифицированные цементно-песчаные растворы. Методы: определение подвижности смесей, прочности при изгибе и при сжатии по ГОСТ; термический анализ; электронная микроскопия. Результаты. Представлены сравнительные результаты исследований по влиянию добавки микрокальцита разных месторождений на свойства цементных систем. Показано, что введение добавки микрокальцита (MCa) Дальнегорского горного карьера повышает прочность на сжатие цементного камня в первые сутки на 16 %, но на 3 и 7 сутки прочность у модифицированных образцов снижается относительно контрольных образцов. Введение добавки MCa Ново-Ивановского карьера, вблизи г. Полевского, ООО «Эверест» в количестве 5 % от массы цемента существенно повышает предел прочности при сжатии цементного камня, способствует образованию дополнительного количества низкоосновных гидросиликатов кальция, стабильных высокоосновных гидроалюминатов кальция с разросшейся игольчатой структурой, затягивающей поры.

Published: January 2023

Recientemente, en el Perú, la SMV ha emitido un Precedente de Observancia Obligatoria en el que se ha puesto en cuestionamiento algunos aspectos referentes a dos fideicomisos de titulización. Esto debido a que, desde la visión de la SMV, los títulos emitidos con cargo a dichos patrimonios fideicometidos no habían cumplido con los requisitos para ser tipificados como valores mobiliarios, en concordancia con la normativa aplicable al caso.El presente artículo tiene como finalidad abordar ciertos alcances respecto de los procesos de titulización de activos y la regulación que les resulta aplicable en el contexto peruano.
¿Tener una buena calificación crediticia sin haber pedido antes un préstamo? Una propuesta para la inclusión financiera
Authors: Delgado Yábar María Paz
Published: January 2023

La inclusión financiera es un proceso y un reto, especialmente en países como el Perú, donde existen muchas personas ajenas al sistema financiero. Por ese motivo, la autora aporta una idea de negocio y una propuesta de regulación que podría ayudar en uno de los aspectos que afecta a la población no bancarizada, no contar con un récord crediticio.La ausencia de calificación crediticia lleva a que muchas personas sean rechazadas por el sistema financiero formal, creándose de esta manera un círculo vicioso que decanta en el desarrollo de un sistema financiero informal paralelo. El artículo propone una novedosa manera de ayudar a las personas a crear un historial crediticio y así poder acceder a más productos financieros a costos menores.
El riesgo legal en el sistema financiero: Una mirada práctica a la naturaleza cualitativa de este riesgo y su impacto
Authors: Pineda Galarza John
Published: January 2023

En el presente artículo, el autor presenta la definición de riesgo y su vinculación con el derecho financiero. En esa línea, plantea una definición legal a la luz de Basilea II, identificando y definiendo los 3 pilares que lo componen. Asimismo, se muestra la vinculación de dichos pilares con las normas de regulación bancaria. Según el autor, dicha vinculación responde a que las normas presentan una variable de riesgo en su estructura, creando, en algunos casos, situaciones de incertidumbre legal ante ciertos supuestos.Al respecto, a lo largo del artículo se desarrollan los tres pilares del riesgo legal, a través de su aplicación práctica en la regulación financiera. Asimismo, se evidencia y explica la naturaleza cualitativa del riesgo legal, con el fin de mostrar su impacto en el negocio bancario; para ello, el autor plantea diversos casos prácticos y de ayuda visual, tales como cuadros y gráficos que facilitan su comprensión.
La cláusula de aceleración en las operaciones financieras
Authors: García Long Sergio
Published: January 2023

El presente trabajo desarrolla la estructura contractual de la cláusula de aceleración, o vencimiento anticipado del plazo del contrato. Este pacto es típico de los contratos de financiamiento y es el remedio contractual por excelencia para recuperar el capital desembolsado y la ganancia total esperada del contrato.Aunque la ley reconoce este remedio para ciertos supuestos, la práctica contractual ha propuesto un esquema más complejo que se acomoda mejor a los riesgos involucrados en un financiamiento. Estudiar a la cláusula de aceleración permite superar el divorcio que se observa entre los remedios legales del Código Civil y los remedios convencionales de la práctica contractual financiera.
Living in Transit
Authors: González Montero Sebastián Alejandro
Published: January 2023

Living in Transit: being in motion is an actual condition. Movement is real. Moreover, it is essential because it concerns kinetic events. We can insistently perceive that everything changes and moves. All living beings undergo experiences revealing flows, adaptations, and becomings. Quotidian experiences testify to that. Directly or indirectly, we face reality's movements all the time. Atoms move. Planets move. Animals move. Rivers move. Trees move. Technology moves. Economy moves. The State moves. And people move. The ontological assertion that reality is all about beings in motion has an anthropological side that must be considered. We indeed live in times highly defined by movement and change. As we have said, everything moves. It is inevitable to perceive and face movement and change. For that reason, it is essential to ethically assess our human role in changing living scenarios and dynamic beings.
