Ts’akiel. Vestidos rituales, prácticas de transfiguración y temporalidades superpuestas en la fiesta del k’in tajimol (Chenalhó y Polhó, Chiapas)

Este articulo intenta mostrar la complejidad de los brocados, de los artefactos y del lenguaje iconográfico en el vestido ritual llamado ts’akiel. Éste, constituido de formas, soportes y materialidades que implican variados procesos memorísticos, integra la concepción de la persona, su grupo de pertenencia territorial y política, tal como se observa en los municipios de San Pedro Chenalhó (municipio constitucional) y San Pedro Polhó (municipio autónomo). Estos vestidos “poseen la historia de los ancestros” que será encarnada por quien se vista con ellos, implicando el hecho de adquirir otra apariencia, como si se tratara de “otra piel”. Cada capa del ts’akiel lleva motivos con forma de animal, de vegetal o de humano y “posee los ojos del ch’ulel”, es decir “las almas que viven dentro del vestido”. Estas últimas revelarán “lo otro del cuerpo” que no sólo implica los huesos y la carne, sino un conjunto de entidades e historias múltiples, que se re-configuran permanentemente en cada municipio.The purpose of this article is to analyze the textiles (woven and embroidered), artifacts and iconography that characterize so-called ts’akiel ritual garments during the Tsotsil people’s K’in Tajimol festival, which takes place in Chenalhó and Polhó (respectively a constitutional municipality and an autonomous municipality in Chiapas, Mexico, which are compared here). Their shapes, materials and materiality involve distinct mnemonic procedures reflecting different aspects of the conception of the person and of the territorial and political membership group. These ritual garments “contain the history of the ancestors,” which is embodied at the festival by those who dress in this “other skin.” Each layer of the ts’akiel is embroidered with animal, plant or human motifs that contain “the eyes of ch’ulel”, that is to say “the souls that inhabit the clothes.” These will reveal “the body’s other,” not only flesh and bones, but also all of the person’s experiences, that is, the constantly reconfigured multiple entities and stories that make up the person.Cet article s’attache à l’analyse des textiles brochés, des artéfacts et de l’iconographie qui caractérisent les vêtements rituels nommés ts’akiel, lors de la fête tsotsil du k’in tajimol réalisée à Chenalhó et Polhó (respectivement commune constitutionnelle et commune autonome du Chiapas, Mexique, ici comparées). Leurs formes, supports et matérialités impliquent des procédures mnémoniques distinctes et renvoient à différents aspects de la conception de la personne ainsi que du groupe d’appartenance territorial et politique. Ces vêtements rituels « contiennent l’histoire des ancêtres », laquelle se voit incarnée lors de la fête par ceux qui se vêtent de cette « autre peau ». Chaque couche du ts’akiel porte des motifs avec des formes d’animaux, de végétaux, ou d’humain qui contiennent les « yeux du ch’ulel », c’est-à-dire « les âmes qui habitent dans les vêtements ». Celles-ci vont révéler « l’autre du corps », c’est-à-dire non seulement les os et la chair, mais également l’ensemble des vécus de la personne, à savoir les entités et les histoires multiples qui la composent et se trouvent sans cesse reconfigurées

Case report of necrotizing sialometaplasia

Introduction: Necrotizing sialometaplasia is a rare inflammatory necrotizing reactive process that can involve minor and major salivary glands. Gland tissue ischaemia has been proposed as the aetiology. Case Report: A 21-year-old woman was referred with a 1-week history of bilateral painful swelling of the palate, with the development of two deep ulcers after the first 3 days. Ulcer edges were elevated but not indurated, and the bases had a necrotic appearance. An incisional biopsy of the margin of one ulcer confirmed the diagnosis of necrotizing sialometaplasia. The ulcers spontaneously healed within 8 weeks without treatment. Discussion: The clinical and histological similarity between this entity and a malignant lesion implies a risk of unnecessary or inadequate treatment. This case illustrates the need for an incisional biopsy to be analyzed by an experienced pathologist to establish a correct diagnosis. © Medicina Oral S. L

Proliferative verrucous leukoplakia : a proposal for diagnostic criteria

Proliferative verrucous leukoplakia (PVL) is a rare form of oral leukoplakia, which was first described in 1985 by Hansen et al. Since then, various published case series have presented PVL as a disease with aggressive biological behaviour due to its high probability of recurrence and a high rate of malignant transformation, usually higher than 70%. PVL is a long-term progressive condition, which is observed more frequently in women and elderly patients over 60 years at the time of diagnosis. Eventually, PVL tends to become multifocal with a progressive deterioration of the lesions, making it more and more difficult to control. Tobacco use does not seem to have a significant influence on the appearance or progression of PVL. These lesions may occur both in smokers and nonsmokers. Nevertheless, at present, the aetiology of PVL remains unclear as well as its management and diagnosis, which is still retrospective, late and poorly defined, lacking consensus criteria. Therefore, the aim of this study is to propose a set of diagnostic criteria to allow for the early and objective identification of PVL cases, and thereby conduct an adequate management. The proposal includes five major criteria and four minor criteria, as well as specific combinations among them in order to establish a correct and objective diagnosis of proliferative verrucous leukoplakia

Combining symbiotic simulation systems with enterprise data storage systems for real-time decision-making

[EN] A symbiotic simulation system (S3) enables interactions between a physical system and its computational model representation. To support operational decisions, an S3 uses real-time data from the physical system, which is gathered via sensors and saved in an enterprise data storage system (EDSS). Both real-time and historical data are then used as inputs to the different components of an S3. This paper proposes a generic system architecture for an S3 and discusses its integration within EDSSs. The paper also reviews the literature on S3 and analyses how these systems can be used for real-time decision-making.This work has been partially funded by the Staff Mobility programme from the Erasmus+ (2020-2021).Onggo, B.; Corlu, CG.; Juan, AA.; Monks, T.; Torre-Martínez, MRDL.

The role of simulation and serious games in teaching concepts on circular economy and sustainable energy

[EN] The prevailing need for a more sustainable management of natural resources depends not only on the decisions made by governments and the will of the population, but also on the knowledge of the role of energy in our society and the relevance of preserving natural resources. In this sense, critical work is being done to instill key concepts-such as the circular economy and sustainable energy-in higher education institutions. In this way, it is expected that future professionals and managers will be aware of the importance of energy optimization, and will learn a series of computational methods that can support the decision-making process. In the context of higher education, this paper reviews the main trends and challenges related to the concepts of circular economy and sustainable energy. Besides, we analyze the role of simulation and serious games as a learning tool for the aforementioned concepts. Finally, the paper provides insights and discusses open research opportunities regarding the use of these computational tools to incorporate circular economy concepts in higher education degrees. Our findings show that, while efforts are being made to include these concepts in current programs, there is still much work to be done, especially from the point of view of university management. In addition, the analysis of the teaching methodologies analyzed shows that, although their implementation has been successful in favoring the active learning of students, their use (especially that of serious games) is not yet widespread.This work has been partially supported by the Spanish Ministry of Science (PID2019-111100RB-C21-C22/AEI/10.13039/501100011033, RED2018-102642-T) and the SEPIE Erasmus+ Program (2019-I-ES01-KA103-062602).Torre-Martínez, MRDL.; Onggo, BS.; Corlu, CG.; Nogal, M.; Juan-Pérez, ÁA.

Simulation, optimization, and machine learning in sustainable transportation systems: Models and applications

[EN] The need for effective freight and human transportation systems has consistently increased during the last decades, mainly due to factors such as globalization, e-commerce activities, and mobility requirements. Traditionally, transportation systems have been designed with the main goal of reducing their monetary cost while offering a specified quality of service. During the last decade, however, sustainability concepts are also being considered as a critical component of transportation systems, i.e., the environmental and social impact of transportation activities have to be taken into account when managers and policy makers design and operate modern transportation systems, whether these refer to long-distance carriers or to metropolitan areas. This paper reviews the existing work on different scientific methodologies that are being used to promote Sustainable Transportation Systems (STS), including simulation, optimization, machine learning, and fuzzy sets. This paper discusses how each of these methodologies have been employed to design and efficiently operate STS. In addition, the paper also provides a classification of common challenges, best practices, future trends, and open research lines that might be useful for both researchers and practitioners.This work has been partially supported by the Spanish Ministry of Science, Innovation, and Universities (PID2019-111100RB-C21-C22/AEI/10.13039/501100011033, RED2018-102642-T) and the SEPIE Erasmus+ Program (2019-I-ES01-KA103-062602), and the IoF2020-H2020 (731884) project.Torre-Martínez, MRDL.; Corlu, CG.; Faulin, J.; Onggo, BS.; Juan-Pérez, ÁA.

Oral and dental health status in patients with eating disorders in Madrid, Spain

The aim of the present study was to describe and compare the oral and dental health status of two groups, one diagnosed with eating disorders (EDs), and another group without this pathology, assessing the following oral manifestations: dental alterations, periodontal disorders, soft tissue disorders, non-stimulated salivary flow, and oral pH. This comparative transversal epidemiological study included 179 participants, of whom 59 were diagnosed with EDs (Eating Disorder Group: EDG) and 120 had no antecedents of EDs (No Eating Disorder Group: NEDG). All patients fulfilled the following inclusion criteria: women aged over 18 years, diagnosed with an ED by a specialist, patients who had undergone at least 1 year monitoring by the Clinical Nutrition Unit, and had not received any periodontal treatment during the previous 6 months. Both groups were homogeneous in terms of sex, age, education, and socioeconomic level. Oral exploration was performed, registering clinical variables, as well as sociodemographic and socioeconomic data, oral hygiene habits, and smoking. Statistical significance was established as p 95%). The dental erosion (DE) was the most significative feature of dental alterations. The degree of DE was significantly greater in the EDG (p<0.001). A significant association between soft tissue lesions and EDs was found (p<0.001) A notable difference in non-stimulated salivary flow was found between the groups (p<0.001). No significant differences between the groups were found for periodontal status, dental caries, or oral hygiene practices. On the basis of the results obtained, it is necessary to carry out oral/dental examination as soon as an ED is diagnosed with regular check-ups thereafter

An RFM Model Customizable to Product Catalogues and Marketing Criteria Using Fuzzy Linguistic Models: Case Study of a Retail Business

In the field of strategic marketing, the recency, frequency and monetary (RFM) variables model has been applied for years to determine how solid a database is in terms of spending and customer activity. Retailers almost never obtain data related to their customers beyond their purchase history, and if they do, the information is often out of date. This work presents a new method, based on the fuzzy linguistic 2-tuple model and the definition of product hierarchies, which provides a linguistic interpretability giving business meaning and improving the precision of conventional models. The fuzzy linguistic 2-tuple RFM model, adapted by the product hierarchy thanks to the analytical hierarchical process (AHP), is revealed to be a useful tool for including business criteria, product catalogues and customer insights in the definition of commercial strategies. The result of our method is a complete customer segmentation that enriches the clusters obtained with the traditional fuzzy linguistic 2-tuple RFM model and offers a clear view of customers’ preferences and possible actions to define cross- and up-selling strategies. A real case study based on a worldwide leader in home decoration was developed to guide, step by step, other researchers and marketers. The model was built using the only information that retailers always have: customers’ purchase ticket details

EVALUACIÓN CLÍNICA, BIOQUÍMICA Y MOLECULAR DE UNA FAMILIA CON RECURRENCIA DE DEFECTOS DEL TUBO NEURAL.

Se presenta una familia originaria del sur de Nuevo León con recurrencia de defectos del tuboneural (DTN) cuyos productos sobrevivientes se han logrado después del tratamiento preconcepcionalcon folato. Después de las evaluaciones clínicas, bioquímicas y moleculares, seencuentra que los miembros presentan heterocigocidad para la mutación MTHFR 677T y que lamadre y la hija son heterocigotas compuestas 677C/677T – 1298A/1298C. Los niveles de folatosintraeritrocitarios y plasmáticos son normales y sólo el padre presenta niveles levementeincrementados de homocisteinemia. Estos resultados sugieren una interacción entre factoresgenéticos y nutricionales previamente implicados en la patogénesis de los DTN que podrían estarasociados adicionalmente a la recurrencia de este cuadro malformativo.AbstractA family is presented it would originate of the south of Nuevo León with recurrence of neural tubedefects (NTD) whose products survivors have been achieved after the treatment preconceptionalwith folate.
