Clarification of Prosthechea guttata (Orchidaceae) and description of an “old” new Prosthechea species from southern Mexico and Guatemala
Authors: Salazar Gerardo A. , Jiménez-Machorro Rolando , Vieira Tiago L. , Velasco-Gutiérrez Kenia , Maldonado Mayra L. , Duarte Salinas Julian , Santiago Elizabeth , Hágsater Eric
Published: December 2024

Background: Epidendrum guttatum A.Rich. & Galeotti, based on specimens collected by Galeotti in Mexico in 1840, was predated by E. guttatum L. and replaced by Encyclia guttata Schltr. and subsequently by superfluous Epidendrum maculosum Ames, F.T.Hubb. & C.Schweinf.
Questions: The study aimed to show that the concept of Prosthechea guttata of recent authors was based on a misinterpretation of its type material, resulting in the application of the name to a different, undescribed species.
Studied species: Prosthechea guttata (Schltr.) Christenson and P. sanchezii Salazar, R.Jiménez & T.L.Vieira.
Study site and dates: Southern Mexico and Guatemala, 2004-2024.
Methods: Study of type material and its comparison with recent collections; field work; documental and herbarium research.
Results: The identity of Epidendrum guttatum A.Rich. & Galeotti (now Prosthechea guttata) is clarified, showing that recent authors have misinterpreted that morphologically distinctive species restricted to the Sierra Madre del Sur, Oaxaca, Mexico, confusing it with an undescribed species distributed east of the Isthmus of Tehuantepec in Oaxaca and Chiapas, Mexico and in Guatemala. The latter is proposed here as a new species, Prosthechea sanchezii, distinguished from genuine P. guttata, and all other Prosthechea species, mainly by the echinate-warty crests on the outer surface of the sepals.
Conclusions: Prosthechea guttata and P. sanchezii are two distinct species historically confused but easily distinguished by morphological attributes, each distributed on opposite sides of the Isthmus of Tehuantepec.
Analytical study of the influence of characteristics of the beam and undulator field on the free electron laser radiation
Authors:   Lomonosov Moscow State University, ZHUKOVSKY K.V.
Published: December 2024

Based on the analytical description of free-electron laser (FEL) radiation, the influence of electron beam parameters on the FEL radiation characteristics is investigated. The effect of the beam cross section, its emittance, Twiss parameters, and energy spread on the FEL gain length and the harmonic radiation powers is analyzed. The influence of the second harmonic of the undulator field on the FEL harmonic radiation, in particular the second one, is also clarified. As an example, the LEUTL FEL is considered as a light source in the visible range with well-documented characteristics. In studies of the material and surface properties, the FEL is used as a light source. In this case, nonlinear second-harmonic generation (SHG) in matter is analyzed. In order to isolate the analyzed SHG response against the background of the source second-harmonic radiation, the possibilities of FEL second-harmonic suppression are studied. An analytical study of the influence of beam parameters and undulator field on the FEL second-harmonic radiation is carried out. It is proposed to use an increased spread of electron energies and the second harmonic of the undulator field in antiphase to the main field to reduce the power of the second harmonic of radiation. The effect can reach several orders of magnitude of the harmonic power.

The 15-μm-pitch 640×512 FPA detectors with a long-wavelength sensitivity limit of 5.1 μm based on MCT layers grown by molecular-beam epitaxy on Si substrates were designed and fabricated. Both electrical circuit and topology of a 15-μm-pitch 640×512 ROIC for such FPAs were developed, according to which multiplexers ensuring operation of manufactured FPAs at a clock frequency of up to 20 MHz were fabricated. Using the flip-chip method on In bumps, hybrid 640×512 MCT-based FPA detectors with 15-μm pixel pitch were obtained. The best fabricated FPA detectors were found to have the following characteristics: mean NETD value < 18 mK and number of non-defective pixels > 99.8%.
Assibilated laterals in acoustics and typology
Authors:   HSE University, Sieber Inna A.
Published: December 2024

Typological studies on sound change, palatalization and consonant harmony consider lateral consonants among liquids and do not pay much attention to lateral fricatives. Researchers show that palatalization transforms lateral sonorants to j or rhotics, whereas lateral fricatives receive only “secondary” palatalization, or additional articulation of palatalization. In this article, I focus on several cases of lateral-to-sibilant change, as a result of palatalization and of high acoustic variability of both laterals and
sibilants. Lateral consonants are characterised by certain invariant properties of their spectrum; however, these consonants are generally characterised by a high degree of cross-linguistic variation. The voiceless alveolar fricative consonant ɬ, which is the most common voiceless lateral, varies cross-linguistically more than any other fricative. I believe that the articulatory properties of laterals predispose them to high variability. Several acoustic characteristics can make laterals and sibilants similar: high intensity, high frequencies, “flat” spectrum. As a result, in some languages laterals can have—either across the board, or conditionally, or sporadically—realisations with a high degree of sibilant noise. In my article, I present three steps of the process: acoustic variation that is neglected in descriptions (Chukchi, Ubykh, Khanty, Andi), alternations in modern languages (Koryak) and reconstructed sound change (Turkic and Abkhaz-Adyghe). The analysis of linguistic reconstructions shows that in the Abkhaz-Adyghe, Turkic and Chukotko-Kamchatkan languages scholars suggest that lateral fricatives changed to alveolar or postalveolar sibilants. In modern Chukotka-Koryak languages there are pairs of words and morphemes similar or identical in meaning and distinguished by the “alternating” lateral or sibilant. To assess sporadic assibilation, field recordings in Khanty, Chukchi, Andi, and Ubykh were analyzed. Spectra and dynamic spectrograms show similarity between ɬ and s, ɬ and ʃ. While numerous examples of acoustic similarity and overlapping between laterals and sibilants can be found in modern languages, they are not discussed in linguistic descriptions or even in specialized phonetic papers. Among the reasons I can suggest perceptual correction that allows the
listener to ignore sporadic assibilations of laterals, which are an intermediate step between the variability of the typical lateral consonant and the assibilations that the phonetic description captures.
From Ludwig Noiré’s tool conception of glottogenesis to Nikolai Marr’s paleontology of language: Controversies of the labor theory of the origins of language
Authors:   Lomonosov Moscow State University, Nikandrov Aleksey V.
Published: December 2024

The article discusses the problem of the connection between two conceptions of glottogenesis, one of which was created at the end of the 19th century by the German philosopher Ludwig Noiré within the framework of his philosophy of language, and the other by the Soviet scientist Academician Nikolai Marr in the framework of his “new theory of language” based on the synthesis of Japhetidology and Marxism. Noiré for the first time in the history of linguistics, even before the appearance of the works of Friedrich Engels, developed a holistic synthetic concept of the labor origin of the language, showing the role of labor tools not only in glottogenesis, but also in anthropogenesis. The author poses the problem of the conformity of Marr’s doctrine to Marxism and shows that it was more important for Marr to present his own teaching as Marxist than to really rely on the provisions of Marxism in posing and resolving the problems of the origin of language. In his works on the theory of the origin of the language, Marr puts forward an extraordinary hypothesis of the “zero stage” of language. He postulates the thesis of a linear (manual, or kinetic) language as a precursor to a sound (spoken) language. The author shows the conceptual similarities and differences between the paleontological conception of Marr and the paleoanthropological theory of Noiré. Based on this analysis, the author establishes the relationship between the two conceptios. The starting point that unites these two theories is the principle of the labor origin of language, which is interpreted differently by the two scientists. In connection with the problem of the influence of Noiré’s ideas on Marr’s conception, the author also discusses some aspects of the creation of the “new theory of language”, in particular, the role of the historian of Ancient Rome Sergey Kovalev as a systematizer of Marrism, who developed an algorithm for transforming Marr’s Japhetic theory into “Marxist linguistics”. The author also reveals the role of Alexander Bogdanov as a proponent of Noiré’s conception and the role of Abram Deborin as the author of the philosophical version of the “new theory of language”.
Typology of public discourse of the modern Spanish monarchy through the speech acts theory
Authors:   Lomonosov Moscow State University, Raevskaya Marina M. , Selivanova Irina V. ,   National Research University Higher School of Economics
Published: December 2024

The article discusses the typology of public speeches of the Spanish monarch Philip VI through the theory of speech acts. Philip VI’s speeches, being a sample of discourse of power, can be considered a special speech genre that combines properties of political and institutional discourse, as well as a communicative resource necessary for transmitting certain ideas and managing public consciousness. The public discourse of Philip VI has its own typology, which correlates with the components of the pragmatic framework (characteristics of the target audience, the subject of the message and the socio-political context), and also demonstrates certain configurations of speech acts taking into account linguistic forms and speech formulas that form illocutionary frame which is determined by the speaker’s communicative task and intention. We propose to divide the corpus of Philip VI’s speeches into two groups (according to the topics and the target audience – national or international), each of which has its own varieties. The specific division of public communication of the state leader is based on Mikhail Bakhtin’s understanding of the genre, reflecting the specifics of the conditions and the purpose of communication at the content, style and composition levels. The study has shown that, on the one hand, the public speeches of the Spanish monarch are regulated by historical tradition and meet the standard of communication with the target audience, and, on the other hand, they are completely subordinate to the nature of the event, which also determines their genre and configuration of the speech acts presented in them. In accordance with Searle and Austin’s speech acts theory, it has been revealed that the institutional political discourse of the Spanish monarch has a bright intentional orientation, which involves a certain set of lexical (verbs, modal words, periphrastic constructions), syntactic (word order) and grammatical (verb mood) means in each discursive type. The main speech acts, within which the speaker’s beliefs and attitudes are broadcast, are constative and evidential representatives, which serve as the illocutionary framework for all types of royal speeches; directives that reveal the greatest variety of combinations with other intentions and forms of expression; commissives, almost always implemented in an indirect form as representative constatives; expressives, vividly presented in speeches on special occasions, and isolated cases of a declarative in an indirect form. It has been found that the choice of a speech act fully correlates with the functions of speech genres and the communicative task of the speaker.

Este artículo pretende valorar la riqueza alimentaria presente en nuestra Colombia para debatir, de-construir y generar reflexiones en torno al cuidado de la vida y la Madre Tierra, a partir de la reconstrucción de los caminos transitados por las autoras desde múltiples orígenes, desde sus trayectorias pedagógicas y desde las apuestas en y para la formación de maestros para imaginar y hacer posible una educación propia. Es desde allí que se hace remembranza al legado alimentario presente en la sabiduría de los abuelos y abuelas, de los guardianes de semillas nativas, de los campesinos que habitan las montañas y desde las experiencias con los estudiantes de dos universidades donde quizás es posible reconocer que transitamos por un espiral que refuerza los vínculos entre los pueblos y los territorios a través del alimento.
Promesas de felicidad y discursos de violencia en el cine mexicano
Authors: Cisneros José Luis , Yautentzi Díaz Dora del Carmen
Published: December 2024

Este trabajo reflexiona sobre la práctica de violencia, formas y procesos de producción, permitiendo entender como la cultura a lo largo del tiempo, se ha concentrado en la industria del cine como una ominosa expresión del inconsciente, que induce subjetivamente a pesar de que los patrones de comportamiento y las acciones convocadas por el discurso social son parte de lo simbólico real que se valida en la promoción de nuestros comportamientos. El presente trabajo, es resultado de un proyecto de investigación interinstitucional, orientado por el interés de pensar la violencia como un dispositivo que se reproduce como práctica internalizada en nuestra cultura y que fue impuesta a algunas generaciones por una pedagogía de la educación sentimental, expresada en el cine mexicano de la época de oro. Para lograr nuestro objetivo, hemos recurrimos al uso de dos conceptos fundamentales como herramientas de análisis: el habitus de Bourdieu, y el concepto de dispositivo de Foucault, anclados al campo narrativo de cinco películas que simbólicamente muestran en sus secuencias, imágenes y diálogos, la violencia como expresión de la dimensión de la cultura. Bajo esta óptica presentamos un trabajo metodológico de corte descriptivo apoyados en el diseño de una matriz que permitió registrar y analizar los recursos narrativos y escénicos y entornos de violencia ejercida contra las mujeres que formó parte de ese dispositivo pedagógico que ayudó a modelar la conducta estereotipada de la mujer mexicana antes de la influyente hegemonía hollywoodense. De esta manera nos aproximamos a la conclusión que el habitus de la violencia se constituyó en un dispositivo cuya estructura social se externaliza no solo en la acción y construcción de la imagen de las mujeres, sino como una práctica estructurante que condición las formas de actual y pensar en la vida cotidiana respecto de la mujer.
ESTADO, POLÍTICA SOCIAL E MILITARIZAÇÃO DA VIDA COTIDIANA
Authors: Rodrigues Sandra
Published: December 2024

Este artigo busca discutir de modo bastante breve acerca do modus operandi do Estado moderno e de seu aparato burocrático-administrativo nas áreas econômica, política, social e culturalmente determinadas. Por meio de pesquisa bibliográfica de natureza qualitativa, parte-se da hipótese que o aparato burocrático-administrativo do Estado moderno, em períodos de retração das taxas de lucro, como o vivenciado mundialmente desde os anos de 1970, abre espaço à militarização da vida cotidiana como estratégia econômica e política que visa tornar menos constringentes os “males sociais” inerentes à sociabilidade burguesa. Conciliam-se políticas públicas e direitos sociais às ações militares baseadas em formas cada vez mais bárbaras de violência. Esse movimento se expressa como um dos desdobramentos do cenário de crise estrutural em curso (Mészáros, 2000), que tem como uma de suas manifestações o estado de guerra civil permanente, possível de superação apenas pela via da revolução social[1], que permanece em suspensão em face da miséria e da opressão dos trabalhadores produzidas pela dinâmica de acumulação do capital, sob a qual se reconfiguram as condições e relações sociais, bem como a organização política da massa de assalariados e pauperizados, da qual se distancia cada vez mais a apreensão das bases possíveis para a conformação de um programa político capaz de dotar o conjunto do sistema social vigente de uma nova base, isto é, claramente direcionado à construção de uma nova ordem societária.

Published: December 2024

This protocol describes the tissue preparation and immunohistochemical procedures applied to wholemount urethra from the female rat. Wholemount immunohistochemistry keeps structures within the tissue intact, but keeps the tissue flat enough that high resolution confocal microscopy can be employed. This is only suitable for the female rat, as the male rat urethra is too thick and muscular. The antibodies recommended in this protocol are to visualize AAV-PHP.S transfected neuron axons, as well as myelin basic protein and S100.
RIGHT OF WAY CATEGORY AND ITS ROLE IN ORGANIZATION AND FUNCTIONING OF PUBLIC TRANSPORT IN CONTEMPORARY CITY
Authors:   Taras Shevchenko National University of Kyiv, Kyiv, Ukraine, NAHORNYI Tymofii
Published: December 2024

Public transport is one of the strategic priorities for achieving sustainable development goals. The role of public transport in cities and urban areas and its competitiveness in comparison with individual (primarily motorized) transport depends on its convenience for daily travel. The primary objective of any transportation system is to reduce the time required to cover a distance, taking into account the traffic safety. Therefore, the speed and predictability of travel is not only the indicator for the efficiency of a transport mode or a particular route, but also directly affects people’s daily travel choices. It is worth stating the need to prioritize public transport not only at the level of declaring strategic goals, but also directly amongst the urban space at the operational level. At the same time, given the current pace of construction of rapid public transport in cities, in particular the metro, the critical need to prioritize street-running transport, primarily the tramway, comes to the fore. In this article, the author hypothesizes that the presence of a separate right of way for public transport lines is not an only crucial criterion for the efficiency of such a system. The article is divided into two logical components. At the first stage, the author studies the Ukraine’s regulatory framework for ensuring the priority of public transport in the organizational, legal and infrastructural fields, as well as analyzes and expands the theoretical contributions of transport scientists in the field of public transport prioritization. The second stage consists of thematic mapping using QGis software of the current 45 tramway networks in 105 cities in Europe, North America, and Australia in terms of separated right of way from the roadways. For City of Kyiv, the tramway network was analyzed as of 1975, 2022 (including separately the right- and left-bank networks), as well as its alleged future state. The results of the spatial analysis are summarized in a table of city rankings by the coefficient of tramway traffic prioritization.

Published: December 2024

A utilização de energia solar é uma alternativa para geração de energia mais sustentável e econômica. A aplicação dessa inovação no agronegócio tem demonstrado resultados satisfatórios, caracterizando uma possibilidade de aliar produtividade e sustentabilidade. Este estudo investigou as viabilidades técnicas e econômicas da implantação de um sistema integrado de piscicultura familiar à energia solar. Realizou-se o levantamento de carga dos equipamentos elétricos utilizados no manejo diário da piscicultura, estimativa dos equipamentos e quantidades necessárias para o projeto fotovoltaico, bem como o levantamento de custos da implantação do sistema Off-Grid, incluindo materiais, mão-de-obra e impostos para funcionamento legalizado. A partir dos dados analisados, verificou-se que a estimativa do consumo mensal seria de 359,45 kWh. Considerando que a implantação desse sistema será em uma piscicultura familiar, com investimento total de R$ 26.826,99, o payback será de 52 meses, aproximadamente. Tecnicamente, é um projeto que atende às necessidades, por todo o aparato necessário incluído nos cálculos, o que permite o fornecimento de energia mesmo em períodos noturnos, uma vez que alguns equipamentos precisam estar conectados o dia inteiro. Portanto, do ponto de vista técnico e econômico, a implantação do sistema fotovoltaico isolado Off-Grid em uma piscicultura familiar é considerado viável.

Published: December 2024

As vegetables have been growing and space has gathered on the market, there is increasing demand for alternative light sources. This research aimed to analyze the possible changes in lettuce (Lactuca sativa) seed germination and initial seedling growth under different light spectra. Seeds were germinated in a chamber at 20°C under a 12-hour photoperiod. The light treatment in the first phase consisted of white and colored light-emitting diode (LED) lights (red-V + blue-A) in proportions of 100% V, 80% V + 20% A, 50% V + 50% A, and 80% A + 20% V. The first phase of the experiment consisted of a completely randomized design in a 2x4 factorial scheme (two light conditions and four seed lots) with four replications. The first count, germination, germination speed index (GSI), root length, shoot length, total seedling length, and shoot-to-root ratio were evaluated via image analysis. For the second phase of the experiment, the quantification of antioxidative enzyme activity (SOD, CAT, and APX) was performed to assess whether the light treatments (white LED light, colored LED light, and fluorescent light) caused photooxidative damage in the seedlings. Compared with white LED light, colored LED light improved plant germination and growth by promoting faster radicle protrusion, a greater GSI, a longer total seedling length, and a longer primary root length. The quantification of SOD, CAT, and APX activity indicated that the quality of light used in this work did not cause photooxidative stress in lettuce plants.

Published: December 2024

O objetivo deste estudo foi avaliar os efeitos do gelo ozonizado como uma estratégia sustentável para prolongar a vida útil do tambaqui durante o armazenamento. O arranjo experimental utilizado neste estudo foi completamente ao acaso em esquema fatorial (2x5), onde os fatores foram constituídos por dois tipos de gelo utilizados para armazenar as amostras de tambaqui (gelo ozonizado ou gelo comum) e cinco períodos de armazenamento (7, 14, 21, 28 e 35 dias), com 9 peixes (repetições) cada. As amostras de filé de tambaqui armazenadas usando gelo ozonizado apresentaram maior teor de umidade e proteínas (p< 0,05) do que aquelas armazenadas usando gelo comum em todos os tempos de armazenamento avaliados. No entanto, essas amostras também apresentaram menor teor de gorduras e cinzas (p < 0,05). As concentrações de mesófilos e coliformes totais foram maiores (p< 0,05) nas amostras de tambaqui armazenadas usando gelo ozonizado. Não foi detectada a presença de coliformes termotolerantes, Staphylococcus aureus e Salmonella spp em todas as amostras avaliadas, independentemente do tipo de gelo utilizado ou dos tempos de armazenamento. Os resultados de pH, N-BVT e TBARS foram mais baixos (p< 0,05) em amostras de tambaqui armazenadas usando gelo ozonizado em quase todos os tempos de armazenamento avaliados. Os resultados do IQM foram mais baixos (p< 0,05) em amostras de tambaqui armazenadas usando gelo ozonizado até 28 dias de armazenamento.
Suplementação de progesterona injetável de longa ação em pré e pós iatf em vacas leiteiras como estratégia de incremento nas taxas de concepção
Authors: Junior Alcebiades Wilson
Published: December 2024

Efeitos positivos do uso da progesterona antes, durante e após a IATF e abordagens do seu uso em diferentes doses ou dias do ciclo são uma tendência dos estudos em IATF atualmente, em estudos recentes de metanálise, foram observados que os  tratamentos com progesterona, apesar de algumas discordâncias entre os resultados, de um modo geral, melhoraram as taxas de gestação observadas quando a P4 é utilizada entre os dias 3 a 7 após a inseminação, com efeitos mais significativos em animais de fertilidade baixa quando comparado a animais de boa fertilidade. O estudo foi conduzido em uma fazenda da cidade de Unaí-Mg no período de fevereiro de 2021 a janeiro de 2022, um total de 101 fêmeas em lactação foram divididas aleatoriamente da seguinte forma: o grupo P4 antes P4A (n= 25) recebeu 300 mg de P4LA i.m 10 dias antes do início do protocolo (D-10), o grupo P4 antes e depois P4AD (n=25) recebeu 300 mg de P4LA i.m 10 dias antes do início do protocolo (D-10) e 900 mg de P4LA i.m 3 dias após a inseminação, o grupo P4 depois P4D  (n= 22) recebeu 900 mg de P4LA i.m 3 dias após a inseminação e o grupo controle GC (n= 29) recebeu 2 ml de solução salina 0,9 %  i.m no D-10 e 6 ml de solução salina 0,9 % no 3° dias após a inseminação. Neste estudo a suplementação de P4LA em vacas em lactação não se mostrou eficaz na melhoria da taxa de concepção desses animais independente do período que fosse administrado.

Published: December 2024

BACKGROUND: Lung cancer is the second most common cancer worldwide, accounting for approximately 20% of all cancer-related deaths and having a 10% 5-year survival rate for very late-stage cases. For the prevalent non-small cell lung cancer (NSCLC), recent guidelines advise staging based on the 8th edition of the TNM classification, highlighting the importance of mediastinal lymph node involvement. While noninvasive methods are generally accurate, they often lack sensitivity, and invasive methods may not be suitable for all patients. Advances in deep learning present potential in solving such problems. However, most research focuses on algorithm development more than clinical relevance. Moreover, none of them addressed individual lymph node malignancies, limiting comprehensive analysis and interpretability and leaving clinicians without sufficient means to validate the results effectively.
AIM: To develop a local data-trained and validated algorithm for segmenting each mediastinal lymph node in chest computed tomography (CT) and assessing the probability of its involvement in metastasis.
MATERIALS AND METHODS: Initially, IASLC lymph node stations are segmented, providing a bounding box of the mediastinum for further processing. Next, the image is cropped to this box and passed through a second network to identify and mask all visible lymph nodes. Finally, each detected lymph node is extracted, stacked with its mask, and evaluated by a feed-forward network to determine malignancy probabilities.
RESULTS: The pipeline achieved an average recall and object Dice Score of 0.74±0.01 and 0.53±0.26 for the clinically relevant lymph node segmentation task. Further, it recorded a 0.73 ROC AUC for predicting a patient’s N-stage, outperforming traditional size-based criteria.
CONCLUSIONS: The proposed algorithm enables new research algorithms to optimize the management of patients with nonenlarged intrathoracic lymph nodes, thus improving the quality of medical care for patients with cancer.

Published: December 2024

El Principado de Asturias se encuentra inmerso en un proceso de decrecimiento y envejecimiento poblacional. A esto se unen notables desequilibrios internos entre un Área Central que concentra población, actividad económica y servicios, y el resto de la región, donde los problemas se agudizan a medida que nos alejamos del centro. En este contexto, la comarca del Suroccidente presenta los peores registros de Asturias en muchos indicadores. Con el propósito de hacer frente a este escenario, frenar el proceso de declive territorial y revertir la situación a medio-largo plazo se realizó el Plan Especial para los Concejos del Suroccidente Asturiano como un documento estratégico. Para su elaboración se aplicó una metodología de planificación propia fundamentada en el análisis y diagnóstico, el desarrollo de una matriz DAFO-CAME, la detección de necesidades y un intenso y amplio proceso de participación. Todo ello desembocó en una estrategia de intervención integral que, siguiendo las directrices europeas, se basa en el territorio como eje central de la planificación. El documento final, enmarcado en el contexto actual y buscando la cohesión social y el equilibrio territorial, identifica y aprovecha los múltiples recursos endógenos de la comarca e incorpora aspectos sectoriales, transversales y territoriales con un enfoque integrador

Endometrial cancer is the most common gynaecological malignancy in Russia and in the world. Pathological evaluation of lymph nodes is important for staging and adjuvant therapy management. Until recently, systematic lymphadenectomy was the gold standard for staging of endometrial cancer. However, this procedure has been associated with high morbidity and life-long consequences. Sentinel lymph node biopsy is an alternative procedure for staging. We conducted a literature review to evaluate the diagnostic precision, safety and methodology of sentinel lymph node mapping in endometrial cancer.
What is hidden from the view. The problem of chronic and delayed toxicity after immunotherapy based on clinical cases and literature review
Authors: Sobolev M. M. , Pokataev I. A. , Kuzmina E. S. , Galkin V. N.
Published: December 2024

The emergence of immunotherapy has revolutionized the treatment approaches of numerous malignancies. Patients that previously faced a prognosis of only a few months left to live can now enjoy extended lifespans for several years. Nevertheless, it is crucial to acknowledge that immunotherapy carries its own spectrum of adverse events. Notably, the issue of immune-related toxicity is progressively gaining prominence with each passing year. A distinctive feature of these immune-related adverse events is their propensity to transition into chronic conditions, with some manifesting long after discontinuation of immunotherapy. Given the current incorporation of adjuvant immunotherapy regimens in clinical guidelines, it becomes imperative to direct heightened attention towards the challenges associated with chronic and delayed toxicity of immunotherapy.

Authors:   Department of Industrial Design, Chaoyang University of Technology, Taichung, Taiwan, Feng Chung-Shun
Published: December 2024

In recent years, the concept of achieving net-zero carbon emissions by 2050 and the trend of carbon border adjustment mechanisms in Europe and America have been advocated worldwide. Cultural and creative markets have already assumed a highly significant role in people’s daily lives. Consequently, cultural and creative market activities also need to align with the concept of the “Net Zero Carbon Emission Wave.” By implementing net-zero carbon emission activities within small groups of cultural and creative markets, it becomes possible to achieve environmental sustainability.
Cultural and creative markets have often integrated festival events and historical heritage with sustainable environmental concepts. This approach attracts crowds, fostering a sense of local culture and enlivening the environment. Cultural and creative markets have become increasingly popular in Taiwan. These markets serve as friendly venues that combine art, handicrafts, niche brands, and local agricultural products.
This study employs the method of visualizing customer journey in service design. It utilizes semi-structured interviews, observations, and customer journey mapping to record data. Analysis is carried out using task time performance, the System Usability Scale (SUS), and the Questionnaire for User Interaction Satisfaction (QUIS). This approach leads to the formulation of prototype designs for two interface options, labeled as A and B. Relevant experts and scholars are invited to evaluate and provide suggestions. A comparative analysis of experimental tasks is also conducted for the two interface designs.
This study employs a user-participatory approach to involve users in the design and improvement process of the cultural and creative market interface. By integrating sustainability and perpetual concepts to enhance innovative models, the goal is to achieve a more appealing and user-friendly interface. Simultaneously, through a co-creative approach, users are engaged in the creation and design of the interface, thereby increasing their emotional investment in the design and fostering long-term engagement, ultimately leading to sustainable innovative energy. This fusion ensures the sustainable development of the cultural and creative market while also enabling it to generate positive impacts for users and the environment on various levels.

Online courses have become increasingly popular in education and professional development because of their user-friendliness, accessibility, and ability to provide specialized training beyond formal education for workforce preparation. We demonstrate the efficacy of using a Massive Open Online Course (MOOC) to teach specialized engineering concepts through the case study of a multi-body gravitational dynamics course; this topic is not typically taught in undergraduate courses but essential for specialized roles in aerospace engineering. Our use of MOOCs to bridge the knowledge gap between engineering education and practice represents a critical advance in tools for workforce preparation. Our MOOC, Designing the Moonshot, was released to the public in June 2021 and again in June 2022 as part of an international virtual event entitled OrbitCamp (originally called AstroCamp) where we collected data from a sample of 840 participants to study learning gains through pre-post testing and retention. Participant drop-off rates were steep (66% of participants did not complete the first module) but lower among men and those with higher degrees. Statistical analysis demonstrated that participants gained significant knowledge on the 12 (of 14 total) learning outcomes for which sample sizes were sufficient. Some of this knowledge was retained three months after OrbitCamp. These results support the use of MOOCs as a tool for furthering the expertise of the engineering workforce in highly specific domains.
