La influencia temprana de la porcelana china en la decoración artística de la cerámica medieval en España
Authors: Zeng Tian
Published: April 2024

Durante el califato de Córdoba, la introducción de cerámica con esmalte de estaño presenció una influencia tecnológica procedente de la porcelana china, lo que llevó a la diversificación de la producción cerámica local. Los subsiguientes desarrollos complejos durante la dinastía almorávide introdujeron técnicas desafiantes como la cerámica dorada, hasta que en el reino nazarí de Granada surgió la cúspide de la cerámica azul y dorada, exhibiendo una fusión de estilos islámicos, chinos y locales españoles. La influencia de la cerámica azul y blanca de la dinastía Yuan en el periodo posterior se hizo cada vez más evidente, con la introducción generalizada de óxido de cobalto en la cerámica mudéjar y la incorporación de más elementos chinos en la decoración. En el siglo XV, la célebre cerámica de reflejo metálico de Manises y Paterna también exhibió claramente la inspiración decorativa derivada de los intrincados patrones de enredadera de la porcelana Ming. La evolución en el arte de la cerámica no solo reflejó cambios en la apreciación estética, sino que también insinuó un intercambio cultural más profundo entre China y España en las primeras etapas de su encuentro.
El encaje subjetivo del trabajo en las identidades personales: las identidades laborales ante la incertidumbre vital
Authors: Revilla Castro Juan Carlos , Cuenca García Cristina , Fernández Villanueva Concepción
Published: April 2024

El objetivo del trabajo es analizar cómo se reconfiguran las identidades personales ante la dificultad de sostener de forma positiva cualquier identidad laboral. Las respuestas más habituales pasan por otorgar importancia a las identidades familiares, también por las identidades vinculadas con la vida social, el consumo y el ocio. En este contexto, puede ser interesante analizar cómo las personas manejan estos mimbres identitarios para conformar unos arreglos inestables, inciertos, que sirven para orientarse en las incertidumbres de la vida cotidiana. Mediante grupos focales, analizamos las posibilidades de establecer vínculos identitarios positivos con trabajo, familia y vida social en personas de distinta edad y género. Se apunta a un encaje complejo, y diverso, de ese triángulo de identidades. Se muestran las conexiones entre los tres, de forma que las vinculaciones débiles en algunos pueden compensarse con una mayor inversión identitaria en otros, siempre que las condiciones vitales lo hagan posible.
Unpacking the role of workers' heterogeneity in the representation and regulation of platform work. A focus of the case of the Just Eat Takeaway agreement in Italy
Authors: Bonifacio Francesco , Marcolin Arianna
Published: April 2024

This article examines the issue of heterogeneity in relation to workers' representation within digital platforms. Specifically, the research analyses the regulatory process that took place within the food-delivery sector in Italy, investigating how the heterogeneity of couriers is reflected in the Just Eat Takeaway agreement signed in 2021. The novel contribution of this paper is to relate two perspectives – those of workers and unions – that have rarely been considered together in the literature on digital labour platforms. Based on extensive qualitative research in Milan, the heterogeneity of riders is synthesized into a threefold typology identified by three metaphors: the explorer, the entrepreneur and the labourer. It is argued that the introduction of a standard employment contract has led to an increase in workers’ rights and social protection. However, the current form of the agreement favours less vulnerable riders – the explorer – at the expense of those who are more numerous and dependent on platform income – the entrepreneur and the labourer. We conclude that this agreement can be interpreted mainly as a means for trade unions to legitimise their institutional role in the socio-economic arena and strengthen their power resources for future negotiations.
Identidades laborales en la industria del retail en Chile: tramas de precarización, individualización y empresarización
Authors: Stecher Antonio , Godoy Lorena
Published: April 2024

Se discuten tres claves de lectura del sujeto laboral contemporáneo –sujeto precarizado, individualizado, empresarizado– a partir de los resultados de dos estudios cualitativos. El objetivo de dichos estudios fue comprender los procesos de construcción de identidades laborales de trabajadores de tiendas de grandes y modernizadas empresas de la industria del retail en Chile. Se realizaron entrevistas narrativas y grupos focales que abarcaron en total a 127 trabajadores, las que fueron sometidas a un análisis narrativo (entrevistas) y de contenido (grupos focales) buscando dar cuenta del modo en que los trabajadores del sector interpretan sus experiencias laborales y construyen una particular autocomprensión de si mismos. Se identificaron tres tramas de significación –precarización, individualización y empresarización– las que se imbrican entre sí, y se expresan de modos específicos dada las características de la industria del retail en Chile y las particulares y situadas experiencias de sus trabajadores. A partir de dichos resultados se discute el alcance, pertinencia y limitaciones del modo como se han utilizado habitualmente en los Estudios del Trabajo las tres claves de lectura del sujeto laboral contemporáneo señaladas.
Shared Heraldry and the Sacred Space: The Building Blocks of João I of Portugal’s Imagery
Authors: Metelo de Seixas Miguel
Published: April 2024

This study considers the practice of shared heraldry as an instrument of affirmation of late-medieval monarchies, examining the case study of King João I of Portugal. The study of how this sovereign’s heraldry was shared with those close to him illustrates how heraldry was understood as an instrument of propaganda for the cause of independence, in the context of the 1383-1385 dynastic crisis, and subsequently in building the imagery of the King and the dynasty he founded. The transposition of this heraldry to the Monastery of Batalha, erected to commemorate the victory at Aljubarrota and later a dynastic necropolis, established a privileged relationship with this monument’s architecture and iconography, expanding the same theme of shared heraldry (now in a dynastic context) as an expression of the royal power’s legitimacy.
Estudios Visuales e Intermedialidad: el caso del videojuego Assassin’s Creed Unity (Ubisoft, 2014)
Authors: Piñol-Lloret Marta
Published: April 2024

En la actualidad las imágenes son omnipresentes: estamos rodeados de ellas, vivimos por ellas, habitamos en ellas e, incluso, devenimos imágenes. Es por ello que resulta imperativo aproximarnos a la Historia del Arte con una mirada inclusiva que nos permita repensar sus roles y añadir nuevos medios, entre los que destacan los videojuegos. Así, nos hemos aproximado a su análisis a partir de los Estudios Visuales y nos hemos interrogado acerca de la intermedialidad y transmedialidad de una de las entregas de la saga Assassin’s Creed, Unity (Ubisoft, 2014), especialmente relevante para acercarnos a la tecnocultura, a la concreción del espacio en un lugar y como se despliega en los videojuegos, las estrategias que desarrolla este título para apelar a la autenticidad apostando por la verosimilitud y el re-conocimiento en vez de la exactitud, la relevancia del anacronismo, cómo explora las conexiones entre la historia y la memoria, y cómo se sitúa en relación a los géneros. Como se evidencia en el artículo, en los videojuegos se ponen en tensión todas estas cuestiones y se advierte el peso de nuestra memoria visual y el rol que desempeña en cómo percibimos las imágenes y la importancia que les damos.

Published: April 2024

Keberhasilan pembangunan suatu negara sangat tergantung pada efektivitas pengelolaan sumber daya keuangan pemerintah, dan pajak menjadi salah satu aspek krusial dalam menyokong pembangunan. Fokus utama pada pajak penghasilan (PPh) Pasal 21, yang menerapkan tarif progresif untuk menciptakan struktur pajak yang mengakomodasi disparitas ekonomi. Dalam konteks Islam, pajak, atau dharibah, dianggap sebagai transaksi ekonomi yang memberikan kontribusi langsung kepada negara untuk kepentingan bersama.
Penelitian ini menggunakan metode kualitatif dengan analisis kepustakaan, meneliti integrasi PPh 21 dalam ekonomi Islam. PPh 21 mencerminkan keadilan ekonomi dan kemaslahatan umum melalui tarif progresifnya, yang menyesuaikan pajak dengan besaran pendapatan. Dalam Islam, pemungutan pajak dharibah diarahkan pada kesejahteraan umat. Meskipun PPh 21 tidak membedakan antara Muslim dan non-Muslim, sistem ini mencapai prinsip pengumpulan pajak syariah dengan mempertimbangkan keadilan, kemaslahatan umum, dan pemungutan dari golongan ekonomi yang mampu.
PPh 21, sebagai instrumen keuangan, mendukung pembangunan dan kesejahteraan masyarakat dalam kerangka ekonomi Islam. Pemungutan pajak mencerminkan prinsip keadilan, kemaslahatan umum, dan pengumpulan pajak syariah. Ulil Amri, sebagai pemimpin, memiliki peran kunci dalam menciptakan sistem pajak yang mendukung kesejahteraan seluruh masyarakat.

Authors: Akhmedin D. , Kukanova A. , Bekisheva A. , Dzhantemirova N. , Mauletbayev M. , Makishev A.
Published: April 2024

Relevance: In 2022, 370 new cases of newly diagnosed patients with laryngeal cancer and 151 with laryngopharyngeal cancer were
registered in the Republic of Kazakhstan, of which 12.1% of laryngeal cancer at stage IV of the disease and 18.9% of laryngeal cancer. The
one–year mortality rate for laryngopharyngeal lesions was 40.5%, the ratio between one-year mortality and neglect (stage IV) was 2.3%.For T3-4 laryngopharyngeal cancer, today the only operation of choice is circular resection of the laryngopharynx with laryngectomy and
the formation of stomas on the neck. The prospect of disability of patients – the formation of pharyngostomy, esophagostomy, tracheostomy,
constant salivation, the need for probe nutrition, etc., causes irreparable psychological damage to the patient’s personality. In this regard,
the problem of pharyngeal and laryngopharyngeal reconstruction in cancer patients becomes extremely important not only as a stage of
rehabilitation, but also as a necessary element in terms of antitumor treatment of this complex category of patients.
The aim of the study assessment of the significance of pharyngeal defect reconstruction in the surgical treatment of laryngopharyngeal
cancer in order to improve the rehabilitation of cancer patients and optimize antitumor treatment.
Methods: Scientific publications were searched in the following databases: PubMed, Medline, eLibrary, Cochrane Lab, using the scientific
search engine Google Scholar. Criteria for inclusion of publications in the literary review: publications in Russian and English; publications
included in the PubMed, Medline, e-Library databases; publications with clearly formulated conclusions; publications over the past 10 years.
Criteria for excluding publications in the literary review: summaries, reports; articles with paid access; abstracts. A total of 82 sources were
found, and 8 sources were included in the analysis.
Results: The analysis of the world literature made it possible to widely consider the possibility of performing reconstructive plastic surgery
using visceral autografts at the stage of surgical treatment of patients with pharyngeal edema. At the same time, the literature describes
significant reductions in the duration of rehabilitation and improvement of the quality of life of patients, as well as a decrease in the level of
disability of operated patients.
Conclusion: Primary plasty of defects that occur after surgical treatment of laryngopharyngeal cancer, using local tissues, displaced and
free flaps, is undoubtedly the most appropriate way to speed up the rehabilitation of patients and improve the quality of life in the shortest
possible time.
MODERN IMAGING TECHNIQUES IN THE ASSESSMENT
OF MALIGNANCY IN GLIAL BRAIN TUMORS:
LITERATURE REVIEW
Authors: Toleshbaev D. , Ainakulova A. , Zhakenova Zh. , Akimtay K. , Myrzabaeva G. , Ramazan A. , Zholdybay Zh.
Published: April 2024

Relevance: Gliomas represent a major group of primary central nervous system tumors, accounting for approximately 80% of all
malignant brain neoplasms. Recent advances in molecular diagnostics, including the identification of mutations in the isocitrate dehydrogenase(IDH) gene, offer new opportunities to improve the classification of gliomas and to understand the mechanisms of their development. IDH
mutations, which are found in a large proportion of gliomas, are associated with a better prognosis and represent an important biomarker
for the development of targeted therapeutic strategies. Diagnostic techniques, particularly magnetic resonance imaging (MRI), also play
an important role, providing additional ways to assess the morphological and biological characteristics of gliomas, contributing to a more
accurate determination of tumor malignancy and molecular profile, which is key to treatment decisions.
The purpose: To study the possibilities of magnetic resonance imaging in assessing the degree of malignancy of glial brain tumors.
Method: A literature review was performed using the keywords: glioma, IDH mutation, IDH wild-type, MRI, magnetic resonance
spectroscopy (MRS), apparent diffusion coefficient (ADC), diffusion-weighted imaging (DWI), diffusion tensor imaging (DTI), diffusion kurtosis
image (DKI), Susceptibility Weighted Imaging (SWI) in PubMed, BMC Medicine, and Google Scholar databases. The review includes the results
of an analysis of 45 literature reviews on the diagnostic capabilities of molecular diagnostics and MRI to assess the malignancy of gliomas.
Results: This review highlights the importance of current approaches to the diagnosis of gliomas, demonstrating that different grades of
malignancy and IDH mutation status are associated with unique features on MR imaging, including differences in localization, signal, and
enhancement patterns. DTI and DWI extend the ability of MRI to assess tissue microstructure, allowing for more precise tumor characterization.
Studies combining MRI morphologic features, ADC and DTI parameters offer a non-invasive approach to glioma prognosis, highlighting the
importance of integrated use of imaging modalities to improve diagnosis and therapy.
Conclusion: The use of magnetic resonance imaging allows for more accurate morphologic and metabolic characterization of gliomas
in assessing the degree of malignancy, allowing physicians to make more accurate prognostic assessments and select the most appropriate
treatment strategy.
Keywords: Glioma, IDH mutation, wild-type IDH, MRI, magnetic resonance spectroscopy, ADC, DWI, DTI, DKI, SWI

Smelling with the mouthparts in spotted lanternfly
Authors: Dweck Hany K. M.
Published: April 2024

Deciphering how spotted lanternfly (SLF), an invasive polyphagous planthopper in North America, engages with its environment is a pressing issue with fundamental biological significance and economic importance. This interaction primarily depends on olfaction. However, the cellular basis of olfaction in SLF remains elusive. Here we investigate the neuronal and functional organization of the subapical labial sensory organ using scanning electron microscopy and electrophysiological recordings. This organ is believed to supply planthoppers with crucial sensory information that influences their subsequent feeding behavior. We find in SLF that this organ comprises two identical placoid sensilla, each housing two distinct neurons. The A neuron displays a remarkable sensitivity to changes in airflow speed. Importantly, the same neuron also exhibits robust excitatory responses exclusively to three aldehydes out of a diverse pool of 86 tested odorants and inhibitory responses to 62 other odorants. By contrast, the B neuron solely serves as an olfactory detector, showing strong excitatory responses to 17 odorants and inhibitory responses to only three. The results provide a potential cellular basis for the behavioral responses of SLF to its ecologically relevant stimuli. Our study also identifies new odorants that may be useful for managing this serious pest.

Published: April 2024

Introduction: Poor outcomes following the transition from hospital back to community living are common, especially for older adults with complex health and social care needs. Some health care systems now have multiple interprofessional teams (in hospital and community) to support care transitions. These teams will need to be well coordinated to improve care transition outcomes.
Methods: We conducted a scoping review to identify and map peer-reviewed literature on how interprofessional teams are working together to support older adults transitioning from hospital back to the community. We used the six-stage framework developed by Levac and colleagues (2010). Procedures were guided by the Joanna Briggs Institute scoping review guidelines.
Results: Our structured search and screening process resulted in 70 articles, published between 2000 and 2022, from 14 counties. Within these articles, 26 programs were described that used interprofessional teams in both the hospital and community.
Discussion: The qualitative articles suggested that effective teamwork is very important for promoting care transition quality, but the quantitative research did not report on team-related outcomes. Quantitative research has described, but not evaluated, strategies for promoting interprofessional collaboration.
Conclusion: Future research should focus on evaluating processes used to promote effective interprofessional teamwork in care transition interventions.

With the development of society, the improvement of science and technology, and the continuous optimization of production and life, people's living standards are also constantly improving. Therefore, people are starting to pay more and more attention to the comfort level of indoor environment. Housing is not only a place for family reunion and living, but also an important material guarantee for people's lives. However, with the rampant use of decoration materials and the increasing popularity of daily necessities, the hidden dangers of the living environment have greatly increased. Indoor environmental pollution has become one of the serious killers affecting modern human health, seriously affecting people's production and life. Therefore, it is particularly important to monitor the indoor environment, which not only needs to sensitively detect the concentration of various harmful gases, but also has an alarm function to constantly remind of dangers. The main functions of this design include: Connecting the microcontroller with temperature, humidity, and gas sensors to achieve real-time collection and reading of indoor temperature and humidity values, as well as monitoring gas concentration, and achieving the expected results. The display circuit was designed using LCD. The buzzer alarm function was used to automatically alarm when the gas concentration and temperature/humidity values exceeded the set standard values. When the temperature and humidity exceed the limit, the LCD display can immediately prompt and combine with LED alarm. When the gas concentration exceeds the limit, LED alarm is used.

In today's digital era, the security of networked systems is of utmost importance amidst the increasing prevalence of cyber threats and sophisticated intrusion techniques. This paper addresses the critical need for robust network intrusion detection systems (NIDS) in today's digital landscape, amidst escalating cyber threats. Leveraging a dataset derived from a simulated military network environment, we explore various intrusion scenarios encountered in cyber warfare. Reviewing existing literature reveals a spectrum of methodologies, including anomaly-based and deep learning approaches. To enhance current methodologies, we propose a binary classification framework using TabTransformer, a transformer-based architecture, for network intrusion detection. We present detailed methodology, encompassing data preprocessing, model architecture, and evaluation metrics, with empirical results demonstrating the efficacy of our approach in mitigating cyber threats and enhancing network security.
