Les Muses camuses des burlesques
Authors: Nédelec Claudine
Published: September 2020

Au XVII e  siècle, la dénonciation de la crédulité et de l’imagination au profit de la raison, les attaques des Modernes envers l’héritage antique, mettent à distance la figure du poète inspiré – que ridiculisent Saint-Amant et Desmarets. Pourtant persiste chez eux une foi dans une « fureur » d’origine surnaturelle ; de même chez Scarron, avec de l’autodérision et de manière en quelque sorte désacralisée, sous la forme d’un lien « naturel » entre inspiration (burlesque) et corps (grotesque), entre poésie et humeur.
Poète ouvrier, poète inspiré. Les Chevilles de Maître Adam, Menuisier de Nevers
Authors: Ribard Dinah
Published: September 2020

Adam Billaut (1602-1662) est le premier poète ouvrier français, célébré précisément parce qu’il serait extraordinaire qu’un ouvrier fasse de la poésie. Or un auteur ouvrier extraordinaire est forcément mu par une force étrangère à ce qui peut s’apprendre, plus forte que ce qui peut s’apprendre puisqu’il n’a rien appris. Beaucoup des auteurs qui ont contribué au façonnement de cette figure parlent d’inspiration pour mener l’opération sociale qu’était la production d’un poète ouvrier.
Usages de l’inspiration dans les Poésies et Cantiques spirituels de Jeanne-Marie Guyon
Authors: Duyck Clément
Published: September 2020

Cet article veut montrer comment le recueil des Poésies et Cantiques spirituels de Jeanne Guyon (1722) utilise la figure de l’auteure divinement inspirée afin de restaurer le pouvoir charismatique qu’elle a su occuper auprès de ses disciples. Trois dispositifs sont examinés : la préface du recueil qui définit la valeur sacrée de son inspiration ; le péritexte comme manière d’ordonner le déploiement pragmatique de cette inspiration ; le texte poétique comme énonciation « apostolique ».
Ces enfants placés qui deviennent travailleurs sociaux
Authors: Lucas Étienne , Chabant Marc , Basset Julie , Dubéchot Patrick
Published: September 2020

Cet article rend compte de trajectoires de personnes, accueillies dans leur enfance dans des structures de la Protection de l’enfance et devenues travailleurs sociaux. L’exploration de ces parcours vise à comprendre les facteurs qui ont pu déclencher et développer ce choix professionnel, favoriser et permettre ce déplacement social. La parole et les mots de ces personnes évoquent la complexité dans laquelle elles se trouvent durant leur formation et aussi dans l’exercice de leur métier. En effet, il arrive que les enfants, les adolescents ou les adultes aient une histoire fort semblable à la leur, et dans ce cas, comment trouver la « bonne distance » entre leur propre histoire et leur fonction ? Ce sont d’ailleurs parfois des collègues eux-mêmes qui interrogent leur légitimité à occuper un poste et une fonction de travailleur social.

Ces parcours sont facilités par l’accès au microcrédit et ont davantage de chance de réussite quand un accompagnement adapté est proposé. Cet article propose une synthèse des principales dispositions existantes. À partir des expériences de bénévolat d’une des auteurs à l’Association pour le droit à l’initiative économique ( adie ) et d’un entretien semi-biographique analysé avec une créatrice, les auteurs analysent les motivations, l’importance du microcrédit et la pertinence des propositions d’accompagnement personnalisé.
Enrichment of Oxygen Concentration Over Simulated Corneal Surface Through Noncontact Oxygen Delivery Device
Authors: Thaware Omkar C. , Huang David
Published: September 2020

PURPOSE:

To demonstrate a noncontact device to enrich oxygen concentration during corneal cross-linking (CXL).

METHODS:

An oxygen delivery device was tested in a laboratory mock-up. The device comprises a clear polycarbonate tube of 14 cm in length and 1.58 cm inner diameter. Compressed oxygen gas is delivered to the tube from a side opening. The oximeter was attached to a sampling tube 3 mm above the apex of a scleral lens that simulates the cornea. The lens was mounted on a mannequin face. During each experimental run, the oximeter reading was recorded manually every 30 seconds for 4.5 minutes after the flow regulator was opened to the preset flow rate. Three flow rates of 0.25, 0.50, and 1 L/min were tested with all three cornea-tube distances of 8, 10, and 14 mm.

RESULTS:

The baseline oxygen concentration was 20.9%. The oxygen concentration reached plateau levels after 2 to 3.5 minutes. Oxygen measurements were averaged over the three time points in the plateau phase between 3.5 and 4.5 minutes. Atmospheric oxygen concentration above the simulated cornea was found to be strongly dependent on the oxygen flow rate up to 1 L/min. At the 1 L/min flow rate, 99% concentration was achieved at 8 to 10 mm of cornea-tube distances, and dropped to 90% at 14 mm.

CONCLUSIONS:

Atmospheric oxygen concentration can be boosted to more than 90% using a noncontact device. This could potentially improve the effectiveness of accelerated CXL by boosting oxygen transport more than fourfold.

Characteristic of Color-Play on Liquid Crystal Sheet Based on Image Analysis
Authors: Suryantari Risti , Flaviana
Published: September 2020

In this research, we compare two samples of Liquid Crystal sheet (LCs), R30C5W and R35C5W to get information about the characteristic of LCs based on the color-play of the LCs surface caused by increasing of temperature. We analize the color-play of the samples quantitatively by image analysis using hue parameter, texture analysis method by choosing entropy and energy parameter, and color-play area measurement. According to the experiment results, both samples show the similar characteristic in color-play behaviour, illustrated by similar curve for each sample, the different only in the starting temperature of the color-play and the clearing point temperature. The samples also show the same behavior in increasing of the color-play area linearly by increasing of temperature. Based on the graph of hue, entropy and energy parameters, it can be measured the clearing-point temperature of samples at 43 °C and 49 °C for LCs R30C5W and LCs R35C5W respectively. Moreover, the changes of color from red to blue cause the irregularity of pattern illustrated by increasing of entropy values and decreasing of energy values. Study the characteristic of LCs in various types is important particularly before it is used for many application purposes, for instance in heat transfer observation.

Published: September 2020

Rice-based gel is intended to be a coupling agent for usage in ultrasonic application, which made from blending of rice starch powder, sodium hydroxide, carboxymethyl cellulose, glycerin, and water. In this study we test the products for safety and efficacy in 100 patients, by four physicians. The imaging results revealed that, when compared with standard ultrasound gel, rice gel can produce equal clearness but with better echogenicity. So, rice-based ultrasound gel should be an alternative choice for general hospitals.

Published: September 2020

The creation of sustainable hydraulic concrete from the use of waste materials, such as PET bottles, whose performance is better than the conventional concrete, has been a great challenge worldwide within the construction industry. This article shows a study on the application of PET fibers resulting from the recycling of post-consumer bottles, which will help increase their physical and mechanical behavior. Two concrete mixtures were made: a control mixture (M-C), with the proportions of a conventional concrete and a second mixture, adding 0.8% of PET fibers with respect to the cement mass (PR-0.8). Tests of electrical resistivity, ultrasonic pulse velocity, compressive strength, tensile strength and flexural strength were performed at the ages of 7 and 28 days. The results showed a slight improvement in the mechanical behavior of the PR-0.8 mixture, in contrast to the M-C mixture, given that a non-sudden failure occurs; while that the tests of electrical resistivity and pulse velocity indicate that the concrete produced is of good quality and durable.
Prediction of Water Activity in Mamón (Filipino sponge) Cakes by near Infrared Hyperspectral Imaging
Authors: Sricharoonratana Manunchaya , Teerachaichayut Sontisuk
Published: September 2020

Water activity in foods can result in detrimental microbial activity during storage. The usual methods of water activity measurement involve destruction of the sample. Near infrared (NIR) hyperspectral imaging has previously been successfully used as a non-destructive method to determine various physical and chemical characteristics of a variety of foods. Therefore, this method was tested to determine whether it could be used to measure water activity of mamón cakes, a popular sponge cake developed in the Philippines. Individual samples (n = 178) were divided into a calibration set (n=119) and a prediction set (n=59). These samples were tested using NIR hyperspectral imaging (935-1720 nm) with a smoothing spectral pretreatment selected for developing the calibration model. Partial least squares regression was used to establish the model in order to predict the water activity. The results showed the accuracy of the calibration model in prediction that gave a correlation coefficient of 0.767 and the root mean square error of prediction of 0.0130. It was therefore concluded that NIR hyperspectral imaging has a potential for use and application for measuring the water activity of mamón cakes.
Plasticization of Poly(Vinyl Chloride) by Non-Carcinogenic Bio-Plasticizers
Authors: Petchwattana Nawadon , Kerdsap Paramaporn , Sukkaneewat Benjatham
Published: September 2020

In this paper, three different plasticizer molecular sizes namely; glycerol (C3), tributyrin (C15) and trilaurin (C32) was used as non-carcinogenic plasticizers in poly(vinyl chloride) (PVC). The experimental results indicated that all the plasticizers play an important role of PVC toughening. Among of these plasticizers, tributyrin was the most effective for PVC plasticization due to its suitable molecular size. With the presence of tributyrin, PVC was found to tougher and softer which reflected as the increased tensile elongation at break, impact strength and the decreased tensile strength. Morphological study by scanning electron microscope (SEM) exhibited the localized plastic deformations in PVC/plasticized with 15 phr tributyrin. Dynamic mechanical analysis (DMA) showed some shifts of the glass transition temperature (Tg) for all the plasticized PVC compositions. The maximum shift was found when PVC was blended with 15 phr tributyrin. Migration test showed that the plasticizers were easily migrated in ethanol. For the migration in water, it did only slightly.
Bone Marrow Endothelial Cells Take Up Blood-Borne Immune Complexes via Fcγ Receptor IIb2 in an Erythropoietin-Dependent Manner
Authors: Ito Takeshi , Kometani Kohei , Minato Nagahiro , Hamazaki Yoko
Published: September 2020

Immune complexes (ICs) in blood are efficiently removed mainly by liver reticuloendothelial systems consisting of sinusoidal endothelial cells and Kupffer cells expressing FcγR. The bone marrow (BM) also has sinusoidal vasculatures, and sinusoidal BM endothelial cells (BMECs) bear unique function, including hematopoietic niches and traffic regulation of hematopoietic cells. In this study, we found that sinusoidal BMECs express FcγRIIb2, which is markedly increased in anemic conditions or by the administration of erythropoietin (Epo) in healthy mice. BMECs expressed Epo receptor (EpoR), and the Epo-induced increase in FcγRIIb2 expression was abolished in Epor−/−::HG1-Epor transgenic mice, which lack EpoR in BMECs except for BM erythroblasts, suggesting the effect was directly mediated via EpoR on BMECs. Further, although BMECs hardly captured i.v.-injected soluble ICs in healthy mice, Epo administration induced a remarkable increase in the uptake of ICs in a FcγRIIb-dependent manner. Enhancement of the IC incorporation capacity by Epo was also observed in cultured BMECs in vitro, suggesting the direct effect of Epo on BMECs. Moreover, we found that i.v.-injected ICs in Epo-treated mice were more rapidly removed from the circulation than in PBS-treated mice. These results reveal a novel function of BMECs to efficiently remove circulating blood-borne ICs in an FcγRIIb2-mediated manner.
Naive- and Memory-like CD21low B Cell Subsets Share Core Phenotypic and Signaling Characteristics in Systemic Autoimmune Disorders
Authors: Freudenhammer Mirjam , Voll Reinhard E. , Binder Sebastian C. , Keller Baerbel , Warnatz Klaus
Published: September 2020

An expansion of CD21low B cells has been described in a variety of diseases associated with persistent immune stimulation as in chronic infection, immunodeficiency, or autoimmunity. Different developmental stages of CD21low B cells have been highlighted in specific diseases; however, a systematic comparison of distribution, phenotype, and signaling capacity of these populations has not yet been performed to delineate the pivotal character of this unusual B cell population. Screening of more than 200 patients with autoimmune disease demonstrated that the prevalence of patients with expanded CD21low B cells varies between diseases. The expansion was frequent in patients with systemic lupus erythematosus, in which it correlated to relative B cell lymphopenia and duration of disease. Different proportions of distinct developmental stages of CD21low B cells co-occur in nearly all patients with autoimmune disease. Although in most patients, naive-like and CD27− switched memory B cells were the most prominent CD21low subpopulations, there was no detectable association of the pattern with the underlying disease. Despite their distinct developmental stage, all CD21low B cells share a common core phenotype including the increased expression of inhibitory receptors, associated with an elevated constitutive phosphorylation of proximal signaling molecules downstream of the BCR but impaired Ca2+ mobilization and NF-κB activation after BCR stimulation. Further, this was accompanied by impaired upregulation of CD69, although CD86 upregulation was preserved. Beyond maturation-associated differences, the common core characteristics of all CD21low B cell populations suggests either a common ancestry or a shared sustained imprint by the environment they originated in.

Published: September 2020

Hepatitis C virus (HCV) infection is the cause of severe liver disease in many people. The restricted species tropism of HCV hinders the research and development of drugs and vaccines. The Chinese tree shrew (Tupaia belangeri chinensis) is a close relative of primates and can be infected by HCV, but the underlying mechanisms are unknown. In this study, we have characterized the functions of tree shrew MAVS (tMAVS) in response to HCV infection and defined the capacity of HCV replication. HCV was shown to be colocalized with tMAVS in primary tree shrew hepatocytes and cleaved tMAVS at site Cys508 via its NS3/4A protease, with a modulating effect by site Glu506 of tMAVS. The tMAVS cleavage by HCV NS3/4A impaired the IRF3-mediated induction of IFN-β but maintained the activated NF-κB signaling in the tree shrew primary cells. Activation of the tMAVS-dependent NF-κB signaling inversely inhibited HCV replication and might limit the establishment of persistent infection. Overall, our study has revealed an elegant example of the balance between the host defenses and HCV infection via the MAVS-mediated antiviral signaling and has provided an insight into the mechanisms underpinning HCV infection in the Chinese tree shrew.
Nutritional Modulation of the Microbiome and Immune Response
Authors: Burr Ansen H. P. , Bhattacharjee Amrita , Hand Timothy W.
Published: September 2020

The evolution of the immune system, diet, and the microbiome are interconnected. Dietary metabolites modulate the cells of the immune system both directly and indirectly via shifts in the composition of the intestinal microbiota and its products. As a result, overconsumption and malnutrition can have substantial effects on immune responses and inflammation. In resource-rich nations, diets high in processed foods, fat, and sugar can contribute to chronic inflammatory conditions, which are on the rise worldwide. Conversely, in resource-poor countries, malnutrition associated with food insecurity can lead to immunodeficiencies and shifts in the microbiome that drive intestinal inflammation. Developing a deeper understanding of the relationship between diet, microbiota, and the immune system is of huge importance, given its impact on inflammatory diseases and its potential as an easily modifiable mediator of immunomodulation.

2020 Distance Meeting: Farewell to Professor David Yaffe - A pillar of the Myogenesis Field
Authors: Singer Robert H.
Published: September 2020

David Yaffe, PhD passed away on July 3, 2020 at the age of 91. His funeral and burial were held at his kibbutz in Israel, Givat Brenner. At the time of his death, he was emeritus professor of molecular cell biology at the Weizmann Institute of Science. If there is one word to describe David, it would be “pioneer”, Halutz in Hebrew. He participated in the birth of his country as a soldier during the War of Independence, contributed his efforts to expanding the kibbutz movement and the nascent scientific community in Israel. He was a major figure in creating the field of muscle cell biology by generating the immortalized cell lines that could be induced to differentiate into muscle fibers in tissue culture. This made myogenesis a prime candidate for studying cell differentiation, accessible to hundreds of scientists during the dawn of molecular cell biology. Many prominent scientists, among them students of David made their careers on studying the molecular events that occurred as the myoblast cell lines developed into the syncytial myofibers that twitched spontaneously. This opened the field to studies on muscle diseases, such as muscular dystrophy, that could then be addressed through a tractable model for molecular studies. David claimed he was never paid for his scientific activities; his salary at the Weizmann Institute went directly to the kibbutz in compensation for his time taken away from work there. He never knew what his salary was, he said, since it was negotiated between the kibbutz and the Weizmann. Even so, he had to take off weeks from his science occasionally to perform daily tasks, usually in the kibbutz dining hall washing dishes. Disconnected from the material aspects of life, David was driven solely by his love for nature and science, which he continued until the very end. David remains an inspiration to all of us. In this issue several of David Yaffe’s lab members, pupils, coauthors and colleagues meet at a “David Yaffe myogenesis distance meeting" to pay tribute with their collective reflections.

satisfying Oinarov condition, the supremum-involving Hardy-type operators

Rf(x)=\sup_{x\leq\tau < b}u(\tau)\int_0^\tau k(\tau,y)\sigma (y)f(y)dy, x > 0

in Orlicz-Lorentz spaces are investigated. We obtain sufficient conditions of boundedness of

and

R: \Lambda_{u_0}^{G_0}(w_0)\rightarrow \Lambda_{u_1}^{G_1,\infty}(w_1)

. Furthermore, in the case of weighted Lorentz spaces, two characterizations of the boundedness of the operator

R:\Lambda_{u_0}^{p_0}(w_0)\rightarrow\Lambda_{u_1}^{p_1,q_1}(w_1)

are achieved as well as the compactness of the operator

R

is characterized. It is notable that in the present paper the spaces are only required to be quasi-Banach spaces other than Banach spaces.

Published: September 2020

The present study focuses on a novel method to integrate the electro-oxidation process with membrane bioreactor to reduce biofouling and increase the biodegradability index. Here, we used electro-oxidation as pretreatment with membrane bioreactor operating at a current density of 1.5 mA/cm2 with hydraulic retention time at six h. The mixed liquor suspended solids concentration was maintained constant at 3,200 mg/L throughout the experiment for 30 days. The results obtained were promising with the percentage removal of COD, TOC, total nitrogen, and chlorides were in the range of 97%, 90%, 94%, and 15%, respectively, which was comparatively higher than the existing membrane bioreactor. The biodegradable index of treated water was higher, reaching a maximum of 0.6, which is remarkably high compared with 0.3 in a membrane bioreactor. The integrated electro-oxidation process was efficient for the complete removal of pollutants from wastewater, which was confirmed using gas chromatography. In addition, the phytotoxicity test showed a significantly higher quality of treated water compared with that of raw tannery effluent. Hence, our proposed integrated electro-oxidation process can be used to decrease biofouling with increased biodegradability index as a replacement for MBR.
Mandatory and Default Rules in Polish Company Law
Authors: Gliniecki Bartłomiej
Published: September 2020

Company law regulations provide opportunity of individual shaping some of companies’ and partnerships’ rules of operation. Proper determination of those regulations which may be modified by adopting different rules in articles of association (company statues, partnership agreement) is important as far as legal safety of corporate regulations is concerned. Abusing or misunderstanding of company law regulations may lead to invalidity of contractual arrangements that would infringe mandatory regulation of company law. The article provides a general view on the principle of freedom of shaping company articles of association in Polish company law as well as ways of distinguishing between mandatory, semi-mandatory and default rules in Polish company law. Apart from general remarks and indications helpful in understanding Polish law, it also provides specific examples of company regulations in Poland and references to company law rules in other European countries.

Assim, verificou-se que os mapas mentais confeccionados pelos alunos foram importantes no entendimento da matéria estudada e na própria confecção, interagindo uns com os outros, e na oralidade, com a apresentação dos trabalhos.

ENFOQUE METROPOLITANO NO LIVRO DIDÁTICO DE GEOGRAFIA
Authors: Ribeiro Ivandra Alves , Paz Otacílio Lopes de Souza
Published: September 2020

A abordagem sobre Geografia Urbana, especificamente, o enfoque metropolitano dentro das aulas de Geografia consiste em uma forma de articular as escalas locais, regionais e mundiais. Isto se tem, através da conceituação sobre metrópole, região metropolitana e da compreensão sobre as relações verticais e horizontais estabelecidas entre as cidades através da rede urbana. Assim, objetiva-se a compreensão através de uma visão crítica sobre a abordagem e a ênfase atribuídas ao enfoque metropolitano nos livros didáticos de Geografia para o Ensino Médio. A metodologia para seleção das coleções analisadas consistiu em quantificar os dados de tiragem e de valor de aquisição dos livros adquiridos pelo Ministério da Educação, selecionando os mais relevantes e os com menos expressão de aquisição. Para analisar os livros didáticos, os conceitos referidos ao enfoque metropolitanos foram identificados e analisados quanto à sua contextualização e relevância nos livros. Considera- se que existe um conjunto de fatores que devem ser integrados para a sintetização da análise dos conteúdos geográficos dos livros didáticos, que consiste não apenas em atributos textuais, mas também na consideração do pluralismo das realidades existentes no cenário educacional brasileiro.

Authors: Nascimento Bentes Rodrigo
Published: September 2020

A presente pesquisa busca analisar o uso das Tecnologias Assistivas (TA) na educação, através de materiais de baixo custo como contribuinte no processo de ensino-aprendizagem nos conteúdos de Geografia para alunos com Surdez. Compreendendo as particularidades de cada indivíduo, o uso de TA pode contribuir com a assimilação de conceitos associados à disciplina e motivar o uso de ludicidade com o auxílio das atribuições existentes da cultura surda, de forma a construir significância a partir de suas adaptações, promovendo interação e a produção do conhecimento com ações educativas que diferem das propostas tradicionais já conhecidas. A abordagem metodológica da pesquisa é de cunho qualitativo com a descrição dos relatos de experiência dos participantes a partir de uma série de problemáticas criadas para desenvolver didáticas assistivas, instigando a formação de ideias e concepções inclusivas através do proposto pela oficina. Pode-se demostrar que cada situação problema desenvolvida foi bem aceita e em grande parte compreendida com êxito. Dessa forma, vale ressaltar que o uso da TA, levando em consideração a postura do educador, mesmo outrora não dispondo de recursos tecnológicos avançados, pode contribuir na formação de seus aprendizes com materiais de fácil acesso, construindo atividades de caráter assistivo sendo de suma importância para possibilitar melhor aprendizagem da pessoa surda, incluindo-a e motivando a ser ativa em seu processo educacional.

MÚLTIPLAS LINGUAGENS NA PRODUÇÃO DO SABER GEOGRÁFICO ESCOLAR
Authors: Budin Clayton Jose
Published: September 2020

A proposta apresentada para a participação da mesa-redonda que se intitulava “múltiplas linguagens na produção do saber geográfico” se caracteriza por apresentar práticas docentes relativas a diversas experiências de situações de aprendizagens, nas quais se utiliza distintas metodologias, estratégias, instrumentos de trabalho no ensino da ciência geográfica na educação básica. Para a concepção de produção do saber geográfico baseou-se nos conceitos de aprendizagem situada e raciocínio geográfico. Estes conceitos se aproximavam do que este professor pensa sobre as práticas pedagógicas, e o faz refletir ainda mais sobre como os alunos deveriam ser estimulados para pensar o espaço geográfico, associando a isto diversas linguagens para que fosse feita a leitura e interpretação socio-espacial. As principais atividades pedagógicas foram: leitura, interpretação e produção de imagens, mapas, gráficos, textos; cinema e produção de vídeos e filmes; estudos do meio/trabalho de campo; atuação em teatros e filmes; atividades com músicas (leitura, escuta, interpretação e produção); utilização dos recursos tecnológicos como Google Maps, Google Earth e Waze; e atividades interdisciplinares com professores de outros componente curriculares. Por fim, verificou-se as múltiplas linguagens na produção do saber geográfico escolar, nas quais o professor desenvolveu seu trabalho pensando na aprendizagem situada e no raciocínio geográfico, dando ênfase as dificuldades e anseios dos alunos, de forma contextualizada.

Castellano y vascuence en el apóstol navarro San Francisco Javier
Authors: Verd Conradi Gabriel María
Published: September 2020

Este artículo completa otro que se publicó en 2011 en ATG sobre el vascuence y el castellano en San Ignacio de Loyola. Expone en primer lugar la facilidad para los idiomas de San Francisco Javier, que , además de su conocimiento de varias lenguas europeas, y en especial del portugués, se lanzó a aprender las lenguas orientales que necesitaba para su evangelización: el criollo portugués de la India, el tamil, el malayo y el japonés. Se valora debidamente el papel principal que tenía en él el castellano, su lengua propia, la que se hablaba en el castillo y la zona en que nació, un territorio navarro de lengua romance en contacto directo con Aragón. Después se analiza la cuestión de si conocía el vascuence, un debate planteado entre distintos autores, y acaba con una consideración sobre la condición navarra del santo.

Authors: Del Rey Fajardo José
Published: September 2020

En 1605 se abrirían en la Universidad Javeriana dos clases de gramática, los cursos de Filosofía en 1608, los de Teología Escolástica y Teología Moral en 1612, hacia 1613 la cátedra de Lengua indígena, la cátedra de Vísperas hacia 1616, la cátedra de Medicina en 1636, los estudios de Cánones y Leyes en 1706, y la cátedra de Sagrada Escritura en 1722.
El claustro profesoral lo componían: el Rector, el Canciller, el secretario, los dos Prefectos, los catedráticos de Prima Theologia, de Vísperas, de Moral, de Artes, de Sagrada Escritura, los de Humanidades (los dos catedráticos y el director del Seminario de Letras Humanas), el de lengua chibcha y en el siglo XVIII los tres de derecho civil y canónico. En las aulas javerianas se formó una parte importante del capital humano, religioso y social de lo que sería el virreinato. Además, siempre se mantuvo como ventana abierta a las corrientes intelectuales provenientes de Europa y a la vez centro de suministro de ideas, libros e inquietudes para mejorar las virtudes cívicas y la comunidad del pensamiento. Hemos incluido en el Apéndice la «Bibliografía de los catedráticos de Prima Theologia » como expresión del reto que supone analizar tanto documento inédito

In current conditions it is highly recommended for all educational institutions to carry out online or online-based learning. Online implementation is carried out without meeting face to face with students. However, online implementation in PAUD really requires active participation from parents because of the condition of students who have not fully been able to access the media in online implementation. The purpose of this study is to describe online learning based on collaboration between parents and teachers in early childhood education. The method in this research is using descriptive qualitative research. The results of this study are expected that parents will be more motivated to take a proactive role in the learning process of children through online learning based on collaboration between parents and teachers.
