Authors: Cordoba Rivas Jeniffer
Published: March 2024

Este artículo da cuenta de una revisión exhaustiva sobre los procesos de enseñanza aprendizaje de las áreas experimentales, hace una reflexión crítica sobre la forma de impartir los conocimientos de estas asignaturas consideradas como el pilar del desarrollo cognitivo del ser humano. Reconociendo que el universo está lleno de enigmas de los cuales, muchos han sido explicados o soportados por las disciplinas del saber, matemáticas y físicas que están presentes en el quehacer humano y en la explicación de ciertos fenómenos que rigen la naturaleza; conforme a ello, se mencionaran aspectos relevantes a tener en cuenta como estrategias metodológicas del aprendizaje significativo de David Ausubel evidenciando que la puesta en práctica de los saberes en la cotidianidad genera aprendizaje duradero. Análisis que argumenta que en muchas instituciones orientan las clases de forma teórica dejando de lado la contextualización de los conocimientos y se basan solo en el uso de conceptos. En ese sentido, los procesos de enseñanza deben ser orientados desde la contextualización de sus contenidos con el objetivo de generar un aprendizaje significativo que contribuya al desarrollo de habilidades cognitivas motivando al estudiante a cuestionar sus saberes y autoevaluar el nivel de sus conocimientos por medio de la metacognición.

Risc management: the medical support system in contemporary armed conflict
Authors: CIRLAN Sergiu , MARFIN Andrei , DUMITRAS Vasile
Published: March 2024

Introduction. Contemporary armed conflicts are characterized by a multifaceted blend of combat strategies, encompassing conventional and unconventional weaponry, regular and irregular forces, terrorist actions and acts of organized crime, indiscriminate violence and outside international law.

Material and methods. A retrospective bibliographic study was conducted on the evolution of combat strategies employed by the U.S. Armed Forces, NATO member countries, and international UN Peacekeeping Operations over the past 25 years.

Results. The way of organizing and providing medical assistance in local military conflict differs from the principles governing medical support in major armed conflicts. The staging of the treatment system and the evacuation of the wounded follows a crucial time-based framework known as the '10-1-2(+2)' rule: "10"– immediate measures to stop bleeding within 10 minutes of the injury; "1" – evacuation to the medical treatment facility capable of performing resuscitation and stabilizing vital functions.; "2" – timely transfer to a medical formation equipped for Damage Control Surgery and Resuscitation within 2 hours of the injury; "+2" – performing the surgical intervention, stabilization of vital functions, and diagnostic preparations for strategic evacuation within 4 hours of the injury.

Conclusions. Resulting from the specific particularities of the local military conflict, the planning of medical support as well as the complex of treatment and evacuation measures, force health protection, medical logistics, require adaptation to the real tactical and medical situation created.

Authors: BUGNEAC Veronica , STARCIUC Nicolae
Published: March 2024

Introduction. Bees are very important to balancing different ecosystems around the globe. It’s worth noting that, like animals and humans, bees are affected by different pathogens, such as bacteria, viruses, ecto- and endoparasites, and fungi. Therefore, the health of bee families depends on the veterinary sanitary measures undertaken by the beekeepers in close contact with the veterinarians. The aim of the research is to analyze the impact of the microbial status of bee families during the winter period.

Material and methods.   The research consisted of bee families from the experimental apiary of the Institute of Microbiology and Biotechnology of the Technical University of Moldova. Samples of dead bees, about 50 from each examined hive, were collected for bacteriological research. The morphological properties of the bacterial colonies were studied.

Results. The obtained results demonstrate that a diverse microbial microflora prevails in bee families during the winter period. The results of microscopic investigations confirmed the presence of bacteria of the genus E. coli, accounting for over 50% of bacterial forms, followed by Streptococcus and Staphylococcus with a level of 30%, fungal flora 15%, and up to 5% bacteria of the genus Salmonella spp.

Conclusions. The bacteriological research carried out in bee families after the winter period reproduces the data of persistent bacteriocenosis in bee families during the cold period of the year and allows for predicting the risk of infectious diseases in bees.

Published: March 2024

Introduction. The most important risk factors for lung cancer are the tobacco smoking and residential radon exposure. The study of the interaction of smoking x radon as trigger factor for lung cancer morbidity in the Republic of Moldova was carried out.

Material and methods. Data on tobacco smoking prevalence of the national study STEPS 2021, lung cancer morbidity data of 2012-2020 and data of radon measurements using RADTRAK2 during 2018-2021 were used. Data processing tools included summary statistics and cluster analysis.

Results. The distribution of high radon values, the number of smokers and the lung cancer morbidity is uneven throughout the country. The formation of higher cluster combining all variables has proceeded by the formation of two clusters: 1. lung cancer incidence, lung cancer prevalence, number of total tobacco smokers, number of male smokers, number of female smokers, and number of urban smokers, 2. radon concentration and number of rural smokers.

Conclusions. Study results demonstrate the leading role of tobacco smoking on morbidity among the adult population, regardless of gender in an urban environment with a rather low concentration of radon, and at the same time indicate the cumulative effect of smoking and increased radon concentration in rural areas due to the construction features of houses and lifestyle.

The most pronounced dimension of burnout syndrome was psycho-emotional exhaustion, at 29.2%. Younger age and shorter work experience were more affected among mid-level medical personnel. Medical staff in republican, departmental, and municipal medical institutions were more affected than those in district institutions.

Conclusions. Burnout syndrome was detected in all medical workers involved in healthcare delivery, predominantly manifesting itself through psycho-emotional exhaustion, with varying degrees of intensity among different categories of medical personnel.
Knowledge and practices of using antibiotics by patients with acute respiratory infections
Authors: COTELEA Valeria
Published: March 2024

Introduction. Excessive and inappropriate antibiotic (AB) consumption is associated with the development of antibiotic resistance (AR). Insufficient knowledge and irrational practices in the use of AB for acute respiratory infections (ARI) by patients contribute to the development of AR. Aim: to assess the knowledge and practices of AB use in patients with ARI in order to identify educational needs.

Material and methods. The study included 393 patients with ARI. The standardized Happy Audit-2 questionnaire was applied. Complaints, the frequency of ARI occurrence, administered AB treatment, AB acquisition method, AB compliance, knowledge about AB, and AB resistance were assessed.

Results. AB were used by 40.3% of the patients. Antibiotic treatment was recommended by a doctor in 87.6% of cases, taken independently by 5.6%, recommended by a pharmacist in 5.0%, and recommended by relatives in 1.9% of cases. AB were obtained without a prescription in 6.3% of cases, and household reserves were used in 20.8% of cases. Patients were compliant with antibiotic treatment in 89.7% of cases but 10.3% of respondents did not adhere to the prescribed duration/dosage. 26.7% of respondents believed that AB were effective against viral infections, and 13.8% believed they were harmless to the human body. In 24.1% of cases, respondents were unaware of the adverse effects of AB, including the development of bacterial resistance in 29.7% of cases.

Conclusions. Insufficient knowledge about the effects of antibiotics and irrational usage practices, including self-medication, emphasize the need for strengthening awareness and education measures for potential antibiotic users.

ABSTRACT Introduction. Antimicrobial resistance has been declared a major public health problem. As a result of excesive antibiotic usage, it became an environmental issue. This problem is now more visible in Low-and Middle-Income Countries, where it increases the social burden. One of the newest methods to fight antimicrobial-resistant bacteria (ARB) is by using bacteriophages. Aim Identification and characterization of possible phage targets from waterland. Material and methods The strains were obtained from inpatients and identified using VITEK 2 Compact and culture. The resistance profiles were determined by disk diffusion method and interpreted according to EUCAST metodology. The presence of resistance mechanisms was checked by phenotypic testing. 31 bacterial strains were selected for research. Results K. pneumoniae, P. aeruginosa, Acinetobacter spp., S. aureus, E. coli and Enterococcus spp. were identified. The resistance profile of the isolates showed: 61,5% of K. pneumoniae isolates were PDR, and 23,1% were susceptible only to Carbapenems. E. coli strains were XDR, 71,4% of P. aeruginosa and 75% of Acinetobacter spp. were PDR bacteria. The susceptibility profile of S. aureus strains showed that 3/4 were resistant to Cephalosporins and Fluoroquinolones. Conclusions Combating the AMR phenomenon starts with knowing the pathogens present in the environment. This study is the cornerstone for further research that will ultimately lead to finding suitable phages for water treatment in Moldova, hoping they will reduce the economic and social burden and also, environmental contamination.

Published: March 2024

Introduction. Antimicrobial Resistance (AMR) is one of the most serious threats to global public health, causing over 700 thousand deaths annually. In addition to the social burden, AMR generates high medical costs, and estimating these at the hospital level has been the subject of research in many international studies.

Material and methods. A comprehensive study was conducted, encompassing 172 cases of invasive infections recorded in patients hospitalized at the “Timofei Mosneaga” Republican Clinical Hospital, from which strains of antimicrobial-resistant E. coli, K. pneumoniae, A. baumannii, and P. aeruginosa were isolated in the years 2019-2021. Based on data regarding the duration of hospitalization, treatment costs, and expenses for investigations, indicators such as average cost, the median, minimum and maximum values of treatment, including the cost of antibiotics and laboratory analyses, were calculated.

Results. The economic impact indicators of AMR at the hospital level include: the duration of hospitalization, the total costs of a treated case, the costs of antibiotics, and the costs of laboratory analyses. In the structure of microorganisms isolated from the patients included in the study, K. pneumoniae predominates, accounting for 44.2%, and the total treatment cost for this organism was the highest at 202731.5 dollars. The maximum duration of hospitalization was recorded in patients from whom A. baumannii was isolated (27.7 days).

Conclusions. The resistance of strains isolated from patients has directly contributed to the extension of the hospitalization period. The resistance of A. baumannii and K. pneumoniae species has predominantly led to the increase in the economic burden of AMR.

Published: March 2024

Medicinal plant extracts obtained by chemical methods have drawbacks such as high chemical, time and energy consumption, byproduct formation, lower quality and efficiency, high toxicity and lead to degradation of thermo-sensitive bioactive compounds. The purpose of this study was to investigate the ability of crude xylano-pectinolytic enzymes concoction in bio-extraction of medicinally important plant extracts, in order to reduce the use of chemical solvents for extraction. In this regard, various conditions including material to liquid ratio (MLR), enzyme dose, treatment time and stirring speed were optimized and several physico-chemical parameters including pH, total soluble solid (TSS), total dissolved solid (TDS), clarity, reducing sugar, polyphenolic content, viscosity and filterability were studied. The bio-extraction efficiency was found to be best at material-to-liquid ratio (MLR) 1:5-1:6 (g/mL), enzyme dose range between 15:60 to 20:80 (IU/g), treatment time range between 180- 240 min and stirring speed range between 50-60 rpm. Enzymatic extraction of medicinal plants resulted in 7-17% increase in clarity, 27-50% increase in TSS, 3-42% increase in reducing sugars, 20-42% increase in polyphenolic content, 13-53% increase in TDS, 15-22% increase in filterability along with decrease of 3-5% in pH and 18-43% in viscosity. Hence, this eco-friendly bio-extraction strategy could reduce the chemical usage, along with improvement of the physico-chemical properties of medicinally important extracts. The technique also enables the application of greener chemistry in the pharmaceuticals to optimize cleaner methods of extraction. This is the first report manifesting bio-extraction of medicinally important plant extracts using crude xylano-pectinolytic enzymatic concoction produced by a single bacterial isolate.

Published: March 2024

An important aspect of breast cancer therapy is selection of drug targets in the proliferating cells. Only few studies have focused on spingoshine kinase1 (SphK1); a potential target present in the cancer cells to bind with drug molecules. The structure and physicochemical properties of SphK1 were retrieved. The information of top 12 anticancer drugs were collected from National Cancer Institute (NCI) database and considered as reference drugs based on their drug likeness properties. The drug likeness property values of these drugs are in the range of 0.001 to 2.33, -0.7 to 7.4, -2 to -5.5, 2 to 13, 1 to 6 and 33 to 205 respectively for water solubility, partition coefficient, molar solubility, hydrogen acceptor and donor counts and polar surface area. The values were compared with 15 experimental drugs which were taken from a published article. The range of drug likeness property values of both groups match with each other. SphK1 shows strong binding affinity to the experimental drugs in the range of -8.8 and -5.1. Herein, we describe an effective solution for treating breast cancer by targeting the tumor marker, SphK1.

Application of nanotechnology for the synthesis of silver nanoparticles using plant extract can be a promising alternative to traditional chemical methods. Products of biological origin have less side effects, thus are safe for human health besides being cost-effective and pollution-free. Keeping in view this, the current work was designed for the environment- friendly production of silver nanoparticles (AgNPs) utilising Isodon coetsa acetone leaf extract. The effect of some important variables including incubation time, pH, AgNO3 concentration, temperature and volume of plant extract were examined for the optimum production of AgNPs. Synthesized nanoparticles were further characterized using atomic force microscopy (AFM), X-ray diffraction spectroscopy (XRD), and UV-visible absorption spectroscopy. In addition, the antibacterial potential of nanoparticles was also determined by agar-well diffusion method. The optimal conditions for synthesis of AgNPs achieved after 24 h of incubation at pH 9.0, 2mM AgNO3, 60°C temperature, and using 10% I. coetsa leaf extract. X-ray diffraction spectroscopy revealed that the size of the strongest peak for AgNPs was 9.5 nm, while atomic force microscopy confirmed their spherical shape with smooth surface without any pinholes or cracks. AgNPs showed excellent antibacterial action against Gram-positive and Gram-negative bacteria. The current study has contributed to the development of a simple and fast bioprocess for the synthesis of AgNPs of the appropriate size and form which also have increased antibacterial activity in comparison to crude extract. Therefore, the process of biogenically synthesised AgNPs from plants is a straightforward, commercially feasible, and environmentally benign approach that can be used in disease control while utilizing their important role as therapeutic agent for treating various ailments caused by pathogenic bacteria.

Kidney stone formation and recurring urinary tract infection (UTIs) are common among the general population. An alternative herbal treatment potential was investigated in this study. This study aims to investigate anti-urolithiasis efficacy of herbal Tribulus terrestris (TT) plant leaf extract in reducing the growth of calcium oxalate and struvite crystal using in vitro methods. In vitro antiurolithiatic potential of TT leaf extract was studied using nucleation, aggregation, and crystal formation assays in synthetic media and in synthetic urine samples. In vitro antiurolithiasis potential of Tribulus terrestris (TT) plant leaf extract was investigated at concentrations ranging from 100 to 1000 μg/ml. Initially, the principal phytochemical constituents of TT methanolic leaf extract was examined. Then antibacterial properties of TT plant leaf extract were tested against common urinary tract pathogens such as Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus). The results of the nucleation assay revealed that TT leaf extract reduced up to 55% of calcium oxalate (CaOx) crystallization and inhibits struvite crystal formation up to 85% with 5% (0.43 g) of TT extract. This study revealed a dose-dependent suppression of crystal formation by increased TT plant leaf extract dosage. The antibacterial activity of TT plant leaf extract is greater against E. coli than S. aureus. This anti-urolithiasis potential of TT plant extract can be used as an antidote for individuals who are prone to urinary crystal formation as well as to control urinary tract infections.

Medicinal plants can be used in the development of new drugs in addition to serving as an indigenous source of new compounds with beneficial effects. The medicinal plants and their parts constitute an important wealth. They play a significant role in healthcare services. The main objective of the study was to investigate the antimicrobial activity, antioxidant activity and phytochemical analysis of Dodonaea viscosa Jacq. Extraction was carried out by cold percolation method. The antimicrobial activity and minimum inhibitory concentration of plant extracts was determined by agar well diffusion and resazurin dye method against various pathogenic isolates. Antioxidant activity of most effective extract was measured by DPPH and hydrogen peroxide method. Among all the extracts, acetone extract of D. viscosa showed highest activity against B. cereus (24.12±0.94 mm at 40 μl) followed by S. aureus (18.78±0.59 mm) and S. flexneri (17.50±0.50 mm). The lowest concentration required to inhibit the growth of B. cereus was 0.1562 mg/100μl. Phytochemical analysis of most effective acetone extract of D. viscosa revealed the presence of alkaloids, flavonoids, phenols, terpenoids, glycosides and saponins. D. viscosa acetone extract showed highest DPPH scavenging activity i.e. 80.81±0.24% at a concentration of 300 μg/ml of plant extract. The results indicated that the crude extracts of D. viscosa have a effective antimicrobial potential that provide a source for development of new drug which may be used for the medicinal purposes. Further studies are required to purify the responsible biochemical constituents of important plant materials and also to characterize so as to explore their potential fully.

Published: March 2024

BACKGROUND: Perivascular epithelioid cell tumor (PEComa) is a type of mesenchymal tumor composed of histologically and immunohistochemically distinctive perivascular epithelioid cells. Benign mesenteric PEComa is a rare entity as there has been only one case reported so far. We are presenting a case of benign mesenteric PEComa in a 30-year-old female that presented with abdominal pain and was diagnosed by microscopic morphological examination and immunohistochemical staining. The aim of this case report is to make health-care professionals aware of the diagnostic criteria in similar presentations, treatment modalities offered for this patient, and others reported over the years for malignant as well as benign PEComas and also shedding the light on a new presentation and diagnosis.
CASE REPORT: We reported a case of a 30-year-old female who presented with abdominal pain radiating to the back and rectum. After a thorough physical examination which was unremarkable, a CT scan was done which showed a mesenteric mass. This mass was then resected and sent for histopathology which revealed a PEComa. We report the history, clinical findings, laboratory reports, and gross imaging of a 30-year-old female who presented to our clinic and was diagnosed with a very rare benign mesenteric PEComa.
CONCLUSION: PEComa is a rare tumor, and as PEComas arising from the mesentery being one of the rarer kinds with only 10 cases reported and this case being the 11th, out of those ten cases, only two of them were found to be benign which makes the case we are reporting the second benign mesenteric PEComa reported in English Literature.
A fast matrix completion method based on truncated$ {\mathit{L}}_{2, 1} $ norm minimization
Authors: Liu Zhengyu , Bao Yufei , Wang Changhai , Chen Xiaoxiao , Liu Qing
Published: March 2024

In recent years, a truncated nuclear norm regularization (TNNR) method has obtained much attention from researchers in machine learning and image processing areas, because it is much more accurate on matrices with missing data than other traditional methods based on nuclear norm. However, the TNNR method is reported to be very slow, due to its large number of singular value decomposition (SVD) iterations. In this paper, a truncated $ {\boldsymbol{L}}_\bf{2, 1} $ norm minimization method was presented for fast and accurate matrix completion, which is abbreviated as TLNM. In the proposed TLNM method, the truncated nuclear norm minimization model of TNNR was improved to a truncated $ {\boldsymbol{L}}_\bf{2, 1} $ norm minimization model that aimed to optimize the truncated $ {\boldsymbol{L}}_\bf{2, 1} $ Norm and a weighted noisy matrix simultaneously for improving the accuracy of TLNM. Using Qatar Riyal (QR) decomposition to calculate the orthogonal bases for reconstructing recovery results, the proposed TLNM method is much faster than the TNNR method. Adequate results for color images validate the effectiveness and efficiency of TLNM comparing with TNNR and other competing methods.

Published: March 2024

The adjusted precision of economic values is essential in the global economy. In recent years, researchers have increased their interest in making accurate predictions in this type of time series; one of the reasons is that the characteristics of this type of time series makes predicting a complicated task due to its non-linear nature. The evolution of artificial neural network models enables us to research the suitability of models generated for other purposes, applying their potential to time series prediction with promising results. Specifically, in this field, the application of transformer models is assuming an innovative approach with great results. To improve the performance of this type of networks, in this work, the empirical model decomposition (EMD) methodology was used as data preprocessing for prediction with a transformer type network. The results confirmed a better performance of this approach compared to networks widely used in this field, the bidirectional long short term memory (BiLSTM), and long short term memory (LSTM) networks using and without EMD preprocessing, as well as the comparison of a Transformer network without applying EMD to the data, with a lower error in all the error metrics used: The root mean square error (RMSE), the root mean square error (MSE), the mean absolute percentage error (MAPE), and the R-square (R2). Finding a model that provides results that improve the literature allows for a greater adjustment in the predictions with minimal preprocessing.
Grand Tour et Inquisition romaine

Cette étude est consacrée au cas d’un jeune gentilhomme qui, à la fin du XVIe siècle, en train d’accomplir une sorte de Grand Tour, tombe entre les mains de l’Inquisition romaine, accusé d’hérésie par son professeur de langue espagnole. Le jeune homme arrive finalement à se tirer d’affaire après quelques mois de détention dans les cachots du Saint-Office. Le cas n’en est pas moins emblématique d’une situation politique-religieuse très fragile, marquée par l’avènement d’Henri IV dont le règne n’est pas encore reconnu par le Saint-Siège.
L’Inquisition dans l’Histoire des tromperies des prestres et des moines de l’Église romaine de Gabriel d’Emiliane (1693)
Authors: Morin Jean-François
Published: March 2024

Cet article analyse les représentations de l’Inquisition dans l’Histoire des tromperies des prestres et des moines de l’Église romaine (1693), rédigée sous forme de lettres par le protestant Gabriel d’Emiliane dans le cadre d’un voyage en Italie, puis traduite depuis l’anglais. Ce curieux ouvrage, autour duquel plusieurs doutes et interrogations subsistent, se présente comme un anti-pèlerinage où l’auteur s’éloigne spirituellement de l’Église romaine alors qu’il se rapproche physiquement de son cœur névralgique et qu’il est confronté à la cruauté de l’Inquisition, véritable pierre angulaire du discours anticatholique de l’auteur. En étudiant attentivement la place de l’Inquisition tout au long du texte, en remettant en cause certain de ses postulats et en jouant avec les échelles d’analyse, il s’agira ici de replacer cet ouvrage dans la tradition protestante dans laquelle il s’insère tout en montrant comment s’opère le système de représentations de l’Inquisition d’un huguenot réfugié en Angleterre.
Du blanc au gris, du gris au noir : les métamorphoses de Goya
Authors: Le Guellec Maud
Published: March 2024

Entre décors champêtres et portraits royaux, satires sociales et scènes cauchemardesques, il est impossible d’appréhender d’un seul regard l’œuvre abondante d’un Goya aux multiples facettes. Cette complexité est-elle uniquement le fruit de la production double qui a caractérisé toute sa carrière : tableaux officiels d’un côté, œuvres libres de l’autre ? En réalité, au-delà de cette seule explication, la vie de Goya est marquée par trois grandes fractures, qui expliquent en grande partie les métamorphoses de sa création. Cet article se propose de revenir sur ces trois événements majeurs qui font basculer son univers artistique et de montrer comment chacun d’entre eux a eu des répercussions irréversibles sur ses tableaux, ses gravures et ses dessins.
La (re)conversion chrétienne d’Angélica Liddell : une expérience capitale aux répercussions théoriques et esthétiques
Authors: Chainais Adeline
Published: March 2024

L’artiste Angélica Liddell, connue pour son théâtre baroque et ses excès scéniques, fait l’expérience, en 2014, d’un retour vers la foi chrétienne qu’elle a connue pendant l’enfance et perdue ensuite. Elle trouve dans le sentiment religieux non seulement le réconfort nécessaire pour affronter les différentes douleurs auxquelles elle est confrontée sur le plan personnel, mais également une inspiration artistique, sur le plan tant théorique que pratique, qui va s’avérer déterminante dans l’élaboration de son œuvre théâtrale. Cette étude revient sur les différentes étapes de cette reconversion et sur les répercussions de ce cheminement spirituel sur la conception du théâtre développée par Angélica Liddell ainsi que sur ses différentes créations poétiques et scéniques.
Peut-on parler de révélations en psychanalyse ?
Authors: Fejtö Kalyane
Published: March 2024

El proceso analítico es un proceso largo, similar a una carrera de fondo, durante el cual se destacan ciertos momentos de forma más o menos clara. Estos momentos se caracterizan por realizaciones que pueden calificarse de capitales, en el sentido de que trastornan una lógica psíquica que había prevalecido hasta entonces. Son los contornos de estas experiencias los que intentaremos delinear a partir de la verdad que sería objeto de la “revelación” analítica en el proceso de descubrimiento teórico en la cura analítica.
Le duende du flamenco peut-il être comparé à la révélation en psychothérapie ?
Authors: Riegler Anne-Sophie
Published: March 2024

Le duende, dans le flamenco, s'apparente souvent à une expérience d'intensité susceptible d’induire des changements non seulement esthétiques mais aussi existentiels chez la personne qui l’éprouve. À ce titre, il est parfois rapproché de phénomènes psychiques tout aussi remarquables par leur intensité mais survenant dans d’autres cadres. Nous étudierons ici le bien-fondé d’une comparaison entre le duende et certains moments dits de « révélation » en psychotérapie, à partir d’un dialogue avec l’article de la psychiatre Juliette Allain « Approche du sens du geste en psychothérapie à travers l’expérience du duende ».
El hecho extraordinario: García Morente
Authors: Sánchez-Gey Venegas Juana
Published: March 2024

Manuel García Morente, filósofo español del siglo XX, conocido estudioso kantiano y agnóstico convencido, narra en una obra titulada El hecho extraordinario su experiencia de conversión al cristianismo y, más aún, su vocación sacerdotal. Así pues, el profesor de ética y decano de la facultad de Filosofía y Letras de Madrid explica la experiencia de Dios en su vida, la argumentación previa acerca de la existencia de Dios, mediante la comprensión de los conceptos de determinismo y providencia y, de modo especial, el acontecimiento que marcó su vida personal aquella noche de abril en París.
“Vuelvo y te desconozco”: vocabulario místico y vuelcos espirituales en Báculo de Babel de Blanca Andreu
Authors: Méndez Soria Lucía
Published: March 2024

Cet article analyse le deuxième recueil de poèmes de Blanca Andreu (A Coruña, La Corogne, 1959), une série de visions apocalyptiques qui jalonnent un cheminement spirituel et une méditation sur le pouvoir transformateur, révélateur, de la poésie et sur la survivance du caractère sacré de la parole. L’écriture d’Andreu emprunte un « vocabulaire du mysticisme » (d'après l’expression de Sylvia Sherno) pour construire un univers propre d’images autour de l’animalité, du sang et du feu, se nourrissant de filiations proches du surréalisme ou de l’orphisme.
Las memorias de Mario Onaindia: geminación e iluminaciones
Authors: Olmos Miguel
Published: March 2024

Las memorias de Mario Onaindia dan testimonio de los ingentes esfuerzos desplegados para la construcción de una trayectoria personal y pública en un contexto marcado por graves tensiones históricas, sociales y políticas, tanto en el País Vasco como en España. La activa búsqueda del autor viene guiada por una actitud descreída o escéptica, algunos de cuyos interrogantes aparecen dramatizados en estructuras geminadas de carácter especular, en las que el sujeto se convierte en objeto enigmático de su propia atención. Estas y otras reveladoras correspondencias permiten, por un lado, establecer hitos en el tiempo y articular el curso de la rememoración; por otro, ponen a prueba la coherencia del autobiógrafo, confrontado a la inagotable hondura de la experiencia, vivida o recordada. Dan por último muestras de su dominio de los lenguajes políticos de la época, y las claves esenciales de su evolución ideológica.
« Un coup de dés jamais n’abolira le hasard » : quelques cas de conversions esthétiques au flamenco (XXe-XXIe siècles)
Authors: Trancart Vinciane
Published: March 2024

Este artículo analiza la trayectoria de artistas flamencos que crecieron fuera de Andalucía. ¿Acaso experimentaron una conversión estética o se produjo un fenómeno de aculturación? Este estudio, que se basa en entrevistas con estos artistas, tiene en cuenta la parte de «ilusión biográfica» presentada por P. Bourdieu, ya que los recuerdos mencionados resultan de una reconstrucción, mediante la memoria y el discurso, de sus experiencias. En particular, analizamos los momentos fundacionales clave del descubrimiento del flamenco y las decisiones que llevaron a estos extranjeros a dedicar una parte esencial de sus vidas a un arte a veces alejado de su cultura de origen, pero que ahora forma parte de su identidad. ¿Cuál fue la importancia del azar y de qué manera intervino la libertad en este cambio, más o menos rápido y radical, que resultó de aquel encuentro crucial, e incluso abrumador, con nuevas referencias estéticas?
Más allá del mar, un inmenso jardín. El trato a la figura de Rafael del Riego en la prensa de México, Colombia y Buenos Aires tras su muerte (1823-1830)
Authors: Cañas de Pablos Alberto
Published: March 2024

Après son pronunciamento en 1820, Rafael del Riego est devenu un symbole politique du système du Triennat Libéral espagnol, une référence dans et en dehors de son pays. Pour cette raison, la nouvelle de son exécution en novembre de 1823 est arrivée rapidement en beaucoup d’endroits de la planète. Le cas des territoires américains qui luttaient pour échapper à la métropole présente des particularités car ils constituaient des espaces à la fois proches et lointains et dans des sens différents par rapport à ce qui se produisait en Espagne. C’est la raison pour laquelle la perception de Riego et de son destin après sa mort est très importante pour comprendre la période. En ce sens, la presse est une source primaire d’une richesse particulière. C’est pourquoi, des publications représentatives de trois pays (le Mexique, la Colombie et la Province de Buenos Aires) ont été choisies, qui recouvrent des réalités politiques diverses. Enfin, l’arc temporel comprend sept ans, depuis la mort du héros en 1823 jusqu’à la fin de la décennie, en 1830.
El héroe de las Cabezas: un discutido símbolo constitucional durante el Trienio Liberal
Authors: Sánchez Martín Víctor
Published: March 2024

Rafael del Riego est devenu l’archétype du héros révolutionnaire après son action décisive lors du pronunciamiento du 1er janvier 1820, qui permit le rétablissement de la Constitution de 1812. Dans ce travail, nous analysons quelles bases il avait et comment s’est déroulée la construction, avec un grand succès populaire, de sa figure héroïque sous le canon du héros romantique de la tradition napoléonienne. Ensuite, nous abordons comment il est devenu un symbole constitutionnel grâce à son attitude vigilante, sa figure restant immergée dans les luttes politiques qui se sont produites dans une phase de mobilisation politique intense. Enfin, nous exposerons la lutte entre les factions du libéralisme exalté autour de l’image du héros. Divers groupes ont cherché son soutien pour leurs propres projets politiques, mais la réaction de Riego, déterminé à faire réussir une unité d’action pour le libéralisme devenue impossible, nous montre les limites et les contradictions de son action personnelle.
Du choc de l'image intolérable : les caricatures du génocide des Tutsi
Authors: Sagno Jean Pierre
Published: March 2024

L'article aborde l'interprétation des images choc en analysant le cas particulier des caricatures, et précisément, celles liées au génocide des Tutsi au Rwanda. Nous considérons qu'elles permettent de faire ressortir les spécificités de l'image choc comme mode de représentation du génocide. Une première partie de notre réflexion porte sur le fait que le discours sur l'irreprésentable (ou l'indicible) participe communément à la caractérisation de la représentation des génocides par l'image. Ensuite, nous montrons que la représentation satirique du génocide s'inscrit dans l'univers sémiotique de la violence et de l'horreur. Des analyses d'exemples permettront néanmoins de souligner la diversité des sensibilités et des interprétations suscitées.

Published: March 2024

As security is a serious concern nowadays, it becomes important to develop a product that deals with security issues without any human intervention. Hence, an automatic security system is a proposed device that ensures the security of the premises. Using both emerging technologies and specialized hardware, we can achieve safety goals and be able to develop the proposed device. It is an IoT-based approach that includes cloud computing, OpenCV, and web application for developing a security-based automatic system. Using raspberry pi and software, the authors design an automated security system where all the used electrical items are controlled. This system deals with the protection of possessions, minimizing break-ins, and avoiding any dangerous situations. The additional salient feature is that it also deals with the COVID-19 alerts, which are generated from the temperature sensor. Therefore, it protects the premises not only from any unauthorized access but also protects the premises from any infected person.
