Authors: Huang Xiao-long , Li Ning , Kang Yang , Wang Hui , Weng Chun-sheng
Published: January 2024

In order to study the influence of different nozzle configurations on the gas–liquid two-phase pulse detonation engine (PDE) propulsion performance, the measurement system based on the tunable diode laser absorption spectroscopy (TDLAS) technology is built to measure the velocity and the temperature, while the high frequency dynamic pressure sensor is used to measure the nozzle gas pressure. Based on the momentum principle, the contribution mechanism of unsteady gas jet on thrust is obtained indirectly by TDLAS data. The results show that the impulses of PDE with non-nozzle, convergent nozzle, divergent nozzle and convergent–divergent nozzle are 1.95, 2.08, 1.85 and 2.16 N∙s within 20 ms of the exhaust period, respectively. The analysis reveals that the impulses of PDE with convergent and convergent–divergent nozzles are larger than that with non-nozzle, while the impulse of PDE with divergent nozzle is smaller than that with non-nozzle. The research results in this paper can provide reference for the design of nozzles for PDE.

Authors: Agrawal Mohan , Verma Jai Bhan , Joshi Ganapati N. , Chandel Sunil , Prakash Ved , Mishra Ranjan Kumar
Published: January 2024

This paper reports the numerical investigations to analyze the effect of the application of Gurney Flaps on various configurations in a Low-Pressure Turbine (LPT) cascade in mitigating the laminar flow separation during low Reynolds number operations. T106 LPT blade of chord 60 mm has been selected for the present study. Gurney Flaps of flat type and quarter round type of a particular height of the chord length are selected. Flaps are provided near the blades’ trailing edges for numerical analysis. The numerical computations are performed using STARCCM+ software, and the K-ω SST turbulence Model is used for turbulence closure. The studies are performed at various Reynolds numbers ranging from 37,500 to 138,750 to understand the application of various configurations of Gurney Flap vis a vis turbine blade without Gurney Flap. Performance parameters such as lift coefficient, drag coefficient, aerodynamic efficiency, and static pressure distributions over the blade surface are used to analyse the alterations in the performance of aerodynamic characteristics of the LPT Blade. All the Gurney Flap configurations improved the overall blade aerodynamics. Among these configurations, the flat Gurney Flap configuration is found to be superior as it improves the aerodynamic efficiency of the blade.
The First Case Report of Ketamine-Induced Cholangiopathy in Korea
Authors: Lee Jae Sin , Lee Jong Yul
Published: January 2024

Ketamine is an anesthetic agent for diagnostic and surgical procedures. However, it can produce dissociative anesthesia and induce hallucinations. Therefore, it tends to be abused as a recreational drug. Chronic ketamine use can cause numerous adverse effects including ketamine-induced chlangiopathy and ulcerative cystitis. Ketamineinduced cholangiopathy has been reported since the 1980s and most cases were found in Western countries and South Asia. Here, we report the first case of ketamineinduced cholangiopathy in Korea. Owing to increasing recreational drug use among Koreans, ketamine-induced cholangiopathy should be considered in the differential diagnosis in young patients with cholangitis of unknown etiology.
Ursodeoxycholic Acid Suppresses Epithelial-Mesenchymal Transition via Inhibition of Reactive Oxygen Species in Bile Duct Cancer Cells
Authors: Lee Jin , Hong Eun Mi , Lee Kyung Joo , Park Se Woo , Koh Dong Hee
Published: January 2024

Background/Aim: Reactive oxygen species (ROS) are associated with the growth and invasion of malignant tumors. Ursodeoxycholic acid (UDCA) was proven to block the EGFR-MAPK signaling pathway and epithelial-mesenchymal transition (EMT) in bile duct cancer (BDC) cells. This study was performed to determine the effect of UDCA on ROS activity in BDC cells.Methods: Human extrahepatic BDC cells were cultured. MTT assays evaluated cell viability, and ROS assay kit measured ROS. The western blot assays measured the expression levels of various target proteins. SiRNA was used for silencing of specific genes, and shRNA was used for over-expression of specific genes.Results: UDCA suppressed DCA-induced production of peroxide and ROS, inhibited expression of PRX2, phosphorylated STAT3 and SOD2, and decreased expression of NOX2 and NOX4 in BDC cells. PRX2 and STAT3 were involved in inhibiting EMT by UDCA. UDCA restored the expression of catalase inhibited by DCA in BDC cells. Furthermore, overexpression of NOX4 using shRNA offset the antineoplastic effect of UDCA in BDC cells.Conclusions: UDCA suppresses the production of ROS and enhances the elimination of ROS, inhibiting STAT3 and PRX2 associated with EMT in BDC cells. Accordingly, UDCA contributes to inhibiting the growth and invasiveness of BDC cells via suppression of ROS activity and EMT.

Los vaivenes de la formación inicial del profesorado. Una reforma siempre inacabada.
Authors: Imbernón Francisco , Colén María Teresa
Published: January 2024

Se analiza la actual formación inicial del profesorado de infantil y primaria a partir del nuevo plan de estudios de Grado surgido del Espacio Europeo de Educación Superior. Después de una reflexión sobre la temática se expone una investigación sobre el análisis del actual Grado donde se comprueba, a partir del estudio de la epistemología, la normativa y el currículum, que se continúa formando un perfil de profesorado centrado en su aula, poco implicado en el funcionamiento del centro y menos aún en las relaciones con el entorno escolar. Es decir, la formación inicial del profesorado no ha variado sustancialmente respecto a la de otros planes de estudio anteriores.

Dilemmas of Discrimination Against People with Disabilities in the Health Care System
Authors: Baranauskienė Ingrida
Published: January 2024

In recent decades, there has been a debate in health care practice for people with disabilities that there is already a shift from a medical model to a social model, and new models are developed, such as the human rights model, which can be linked to the United Nations Convention on the Rights of Persons with Disabilities. On the other hand, in many countries, including Lithuania, the analysis of the situation of people with disabilities in the health care system in terms of discrimination is not carried out systematically, and it can hardly be said that this topic is a priority. The scientific study has revealed that this is the case. In this context, the questions naturally arose: what is the situation of people with disabilities in the health care system in Lithuania? Are they discriminated against? If discrimination against people with disabilities persists, what is its manifestation? These and other similar questions reflect the scientific problem of the article. Answering these questions requires obtaining the data of the research, needs, and challenges of people with disabilities, their relatives, and professionals assisting people with disabilities in the Lithuanian health care system were analyzed, which were processed referring to the principles of thematic analysis. The findings of the research prove the multidimensional expression of discrimination against people with disabilities in Lithuania’s healthcare system.

Authors: Ogenler Oya , Okuya Selda , Kerem Filiz , Uzel İlter
Published: January 2024

Introduction: Throughout history, women have sought help from mystical powers to protect them from unexpected situations related to pregnancy and childbirth. The use of amulets in Anatolia, which encompasses the dynamics of products, ideas, beliefs, and civilizations, has been prevalent. Aim: This study aims to explore the connection between amulets used in the Ancient Mediterranean region and medical practices within the context of the history of medicine, utilizing a figurine. Method: Through a detailed examination at the Mersin Museum, a figurine depicting a woman in a crouching position with distinctive facial and bodily features was discovered. The figurine, believed to have been used as a birth-facilitating amulet necklace, was compared with information found in classical medical literature. Findings: The figurine bears resemblance to ancient amulets utilized in the past, which aligns with women’s physiology, childbirth beliefs, and facilitating positions described in ancient texts. Recent studies indicate that women continue to employ amulets as a means of protection against birth-related risks. Discussion: The presence of amulets among archaeological remains draws attention to the enduring influence of superstitions from the past to the present, particularly in situations where the lives of both the mother and child are perceived to be at risk. Conclusion: The historical use of amulets and talismans by women has served as a unifying practice throughout different eras. While these methods are generally regarded as harmless, the ongoing advancement of medicine from its primitive origins suggests that women’s health still faces unresolved challenges.
False Consciousness In Body Positivity Campaigns In Women's Lifestyle Media
Authors: Fadhil Ahmad Raihan , Humeira Bintan , Kurniawan Rizaludin
Published: January 2024

This article aims to discover how women’s lifestyle media constructs a false awareness about women’s bodies through body positivity discourse. Using media and gender perspectives, false consciousness, body positivity, and Roland Barthes’ semiotic analysis, this research finds that the media produces body positivity discourse as a narrative that ‘all bodies are beautiful, whatever their shape.’ Body positivity discourse refers to fat bodies as ‘normality’ to fight the stigma that fat bodies are not beautiful and are a problem for women. Body positivity evolved from the fat acceptance movement. This body positivity discourse is built on the construct that women must accept their body shape to live happily. The media produces the message through photos and texts that fat bodies are delicate as long as they are healthy. It ignores that medical obesity carries serious health consequences for many women. Thus, this research shows that instead of building women’s positive acceptance of their body shape, the media creates a misguided consciousness of fat bodies from a medical perspective.

Published: January 2024

Gelodok fish (mudskippers) are a subfamily of amphibian fish commonly found living in mangrove ecosystems, one of which is in Tabongo Village, Dulupi District, Boalemo Regency, Gorontalo Province. It is difficult to distinguish between species of this fish because they have very similar characteristics. This study aims to (1) determine the detailed morphological characteristics that distinguish gelodok fish species; and (2) determine the molecular characteristics of gelodok fish species found in coastal mangrove ecosystem of Tomini Bay, Tabongo Village, Boalemo Regency, Gorontalo. This research was conducted from 2022 to 2023 using purposive sampling method. Morphological characteristics were performed for 39 characters. Geometric-morphometric analysis was performed using ImageJ software with 10 land marks. Amplification of COI sequences was carried out with F1R1 and F2R2 primers. Based on morphological characteristics, it is known that two species of gelodok fish are found in the area, namely Periophthalmus argentilineatus and P. malaccensis. COI sequencing results of the samples confirmed one species of gelodok fish found in the area, namely P. argentilineatus. The other species cannot be definitively identified as P. malaccensis due to the absence of COI sequences for that species in GeneBank.

Authors: Villena Araya Sofia
Published: January 2024

Introducción: A partir del libro Curaduría de Latinoamérica: 20 entrevistas a quienes cambiaron el arte contemporáneo (2018) de Juan José Santos, se narra la conformación de un campo curatorial latinoamericano desde una perspectiva crítica. Objetivo: Identificar capas de hegemonía que conforman la curaduría durante la década de 1990 y principios de los años 2000, entre procesos de globalización, multiculturalidad y poscolonialismo. Métodos: En este artículo, se adoptan aportes de los estudios queer, específicamente de Judith Butler y Sarah Ahmed, para prestar atención a las dinámicas de poder que atraviesan los intentos por cerrar los discursos. Para esto, se trabajó con fragmentos de entrevistas del libro de Santos. Conclusiones: Se observó la importancia de realizar una historiografía de la curaduría, pensándola no como algo que define a los sujetos, ni como un campo exclusivo de acción, sino como una plataforma de agencia e intervención concatenada con otras herramientas estéticas y experiencias sociales dentro y fuera del arte.
Armonizando resonancias: Sonoridades laborales y litúrgicas a partir de la escucha de Anton Sepp en las misiones jesuíticas a inicios del siglo XVIII
Authors: Gárgano Nicolás Mariano
Published: January 2024

Introducción: En el año 1691, Anton Sepp desembarca en Buenos Aires rumbo a las misiones jesuíticas de Paraguay, dejando en su trayecto una cantidad de cartas en las que describió varios acontecimientos sonoros. Objetivo: Este artículo analiza los relatos de esos acontecimientos para indagar los significados de los sonidos en ese contexto particular. Métodos: Para ello, se analizan dos paisajes sonoros significativos en las fuentes, que eran la jornada laboral y las celebraciones litúrgicas, dando cuenta de los sonidos mismos y sus contextos. Resultados: Los sonidos del trabajo y la liturgia se entrelazaban, regulados por el sonido de la campana que reglamentaba la organización del tiempo, pero durante las festividades estos sonidos convergían, creando nuevo espacio sonoro que reflejaba la visión del proyecto jesuítico misional. Conclusiones: Las sonoridades laborales y litúrgicas no se encontraban segregadas, sino que manifestaban una complementariedad que sintetizaba el imaginario jesuita.
El juego escénico: la utilidad de lo inútil
Authors: Flores Narváez Lisbeth Michelle
Published: January 2024

Introducción: En los últimos siglos, el juego ha sido un tema de estudio y discusión para varias disciplinas del conocimiento humano. El presente ensayo centra su mirada crítica y reflexiva en un tipo específico de juego: el escénico y sus potencialidades ‘productivas’ para la construcción de nuevas y diversas realidades. Desarrollo: La mirada se direcciona hacia el juego en relación con el diálogo lúdico-productivo y hacia el mundo de las personas jugadoras en su accionar, experimentación y creación del juego escénico- teatral. Se atraviesa el juego con base en los postulados de lo lúdico de Johan Huizinga y se complementan con las miradas de Bolívar Echeverría sobre un ethos del juego, Roger Caillois sobre tipos de juegos, y Petronio Cáceres sobre anotaciones del juego en el teatro. Conclusión: Se propone una revaloración de lo lúdico dentro de los valores productivos (estéticos) que puede tener el juego escénico.

Published: January 2024

Lactate, a metabolite of exercise, plays a crucial role in the body. In these studies, we aimed to investigate the role of G protein-coupled receptor 81 (GPR81), a specific receptor for lactate, in regulating lipid storage in the gastrocnemius muscle of rats. To achieve this, we measured the impact of sodium 3-hydroxybutyrate (3-OBA) concentration and time on the cAMP-PKA signaling pathway in the gastrocnemius muscles of rats. Our investigation involved determining the effects of administering 3-OBA at a concentration of 3 mmol L−1 just 15 min before exercise. As expected, exercise led to a notable increase in intramuscular lactate concentration in rats. However, injecting 3-OBA prior to exercise yielded intriguing results. It not only further augmented the cAMP-PKA signaling pathway but also boosted the expression of lipolysis-related proteins such as hormone-sensitive lipase (HSL) and adipose triglyceride lipase (ATGL). Simultaneously, it decreased the expression of fat-synthesizing proteins, including acetyl CoA carboxylase (ACC) and fatty acid synthase (FAS), while increasing the protein expression of cytochrome c oxidase subunit Ⅳ(COX Ⅳ) and the activity of citrate synthetase (CS). Unfortunately, there was no significant change observed in intramuscular triglyceride (IMTG) content. In summary, our findings shed light on the role of lactate in partially regulating intramuscular triglycerides during exercise.
Constructing Religious Organization Collective Identity through Online Media Coverage of Prevention and Handling of Sexual Violence Discourse
Authors: Irdiansyah Achmad Ramdhany
Published: January 2024

This research aims to examine how two religious organizations, Nahdlatul Ulama (NU) and Muhammadiyah, have constructed their collective identity through online media coverage about the discourse of preventing and addressing sexual violence (PPKS). In this regard, this research analyses news stories published by NU.or.id and Muhammadiyah.or.id regarding PPKS discourse. Using a qualitative textual analysis method with thematic analysis and rhetorical analysis approach, the findings have revealed that NU and Muhammadiyah construct their collective identities as da'wah movements, civil society organizations, and cultural groups. As da'wah movements, NU and Muhammadiyah have conveyed their ideas about sexual violence rooted from Islamic values. As a civil society organization, NU has shown symbolic actions that utilize social capital, while Muhammadiyah has expressed through organization programs. As a cultural group, NU has used cultural memory in the form of istigasah kubra, sowan tradition, and Islamic boarding school activities. Meanwhile, Muhammadiyah has used cultural memory in the form of symbols of da'wah works, schools, and campuses to represent itself as a community service and da’wah movement.

Published: January 2024

This research endeavors to understand KH Hasyim Asyari's thoughts regarding wasatiyah da'wah. This study used a textual analysis method with a qualitative content analysis approach. In this regard, the heritage texts (turath) written by KH Hasyim Asyari and the text of a commentator (copyist) of Kiai Hasyim's ideas regarding wasatiyah preaching were inventoried, studied, then analyzed thematically. The results of this study illustrate that KH. Hasyim Asyari used the da'wah method bil-hikmah like when he was convincing Karl von Smith, the architect from Dutch, to convert to Islam. Additionally, he employed da'wah method bil-qalam through writing dozens of books, including those compiled in the title 'Irsyad Al Sari fi Jami Mushannafal al Syaikh Hasyim Asyari'. Further, in preaching wasatiyah, Kiai Hasyim argued that the difference of opinions among Muslims is not on the issue of usuluddin, but rather on furu' al-din, so that the differences with regard to schools of thought should not make Muslim society divided.

Islamic religious activities that are bound together, such as congregational prayers, recitations, and da'wah activities, are some of the things that must be canceled when Covid-19 hits. The decline in social activity, interaction, and public trust is closely related to the increasingly rapid flow of information from various media channels. This research tries to uncover the news about Covid-19 in the mass media in influencing the behavior of the Bandar Lampung community religious activities. The research method used is explanatory quantitative of 422 respondents, obtained by accidental sampling technique. The findings illustrate that there has been an effect of the mass media coverage toward the attitude of the people of Bandar Lampung City, particularly regarding religious activities (35.04%). It has also revealed that the religious community was in a dilemma of choosing between health protection and religious behavior suit to shari'a.
Narrativas de docentes de telesecundaria acerca de las transiciones educativas provocadas por la pandemia de COVID-19
Authors: Gómez- Velasco Jocelyn , Gómez- San Luis Anel Hortensia
Published: January 2024

La pandemia de COVID-19 provocó la mayor interrupción de los sistemas educativos en la historia, afectando alrededor de 1,600 millones de estudiantes, lo que representa el 94% de la población estudiantil a nivel mundial y hasta el 99% de la población estudiantil de países de ingresos bajos y medios-bajos. A consecuencia de ello, se calcula que alrededor de 24 millones de estudiantes podrían abandonar sus estudios. El objetivo de la presente investigación es conocer las narrativas de profesores y profesoras de telesecundaria acerca de su trayectoria docente en tiempos de COVID-19, describiendo los momentos clave y los aprendizajes en el trayecto de la educación presencial hacia una educación remota de emergencia. Participaron cinco docentes de telesecundaria: 3 mujeres y 2 hombres a quienes se les aplicaron entrevistas narrativas individuales de una sola sesión, con duración de una a dos horas. Los resultados indican que la pandemia les representó un escenario de emergencia e incertidumbre, pero al mismo tiempo, una oportunidad de crecimiento y aprendizaje en la que los docentes generaron nuevas, creativas y sensibles formas de continuar con la educación a distancia, incluso en contextos rurales con jóvenes en condiciones vulnerables. Se concluye que el acceso a la tecnología e internet, así como la capacitación en Tecnologías de la Información, Comunicación, Conocimiento y Aprendizaje Digitales (TICCAD), son necesarios para disminuir la brecha entre quienes pueden continuar con sus estudios a pesar de la emergencia sanitaria y quienes están en riesgo de deserción escolar. Ante esta brecha, las estrategias implementadas por docentes durante la pandemia evitaron la deserción de los estudiantes más vulnerables.

Published: January 2024

OBJECTIVES In the past centuries, the concept of “physical education” has changed from a more general concepts including physical activities and sports, to specifically inferring “instruction of physical activity”. Instead, “sports” has become the comprehensive concept of sports, exercise, and physical education. Given to the inconsistent terminologies and English translations of “體育 (ti-yu)” (physical education) and “運 動 (yun-dong)” (sports or exercise) in Mandarin, the purpose of this study was to investigate in the current terminology usage, hierarchy, and the English translation of “體育 (ti-yu)” and “運動 (yun-dong)” in Taiwan.METHODS Three government authorities, two sport related universities, eight top sport and exercise journals, and nighty-six college departments in Taiwan were analyzed.RESULTS “運動 (yun-dong)” was the most widely used terminology as “體育 (ti-yu)” occupied the majority usage among government authorities, sport related universities, and title of top sport and exercise journals. Regarding English translation, despite of “department of physical education”, “sports” remained the most common terminology. Moreover, “體育 (ti-yu)” and “sports” are the highest hierarchy among government authorities, and sport related university; “體育 (ti-yu)” and “physical education” are the highest hierarchy among traditional sport and exercise journals; “運動 (yun-dong)” and “sports” are the highest hierarchy among college departments also the mainstream of current translation and hierarchy.CONCLUSIONS “體育 (ti-yu)” was the highest hierarchy in the past. However, “運動 (yun-dong)” has been the mainstream of the highest hierarchy in Mandarin according to college departments. In English, “sport(s)” is the main term in Taiwan when translating “體育 (ti-yu)” and 運動 (yun-dong)”, also being the highest hierarchy. On the other hand, “體育 (ti-yu)” and “physical education” are utilized regarding those departments focusing on educating PE teachers. This study expects the terminology, English translations, and hierarchy being align with the mainstream of current translation and hierarchy in the future.

Published: January 2024

OBJECTIVES The purpose of the current study was to conduct a meta-analysis to comprehensively analyze and identify research on doping attitudes studied in Korea.METHODS Twelve articles were selected for analysis by searching for ‘doping attitudes’ and ‘doping PEAS’ in Korean academic databases. The meta-analysis was conducted using the meta-analysis package in the R program (ver.4.3.2).RESULTS Results indicated that 12 literatures on Korean athletes’ doping attitudes revealed an average PEAS mean score of 37.20 (95% CI = 34.29, 40.11). Moreover, results found that 10 articles on gender differences in Korean athletes’ doping attitudes showed a small effect size of -0.23 (95% CI = -0.34, -0.12), and a significant difference (p < .0001), with that female had higher mean PEAS scores than males. Results indicated that 4 studies on the difference in doping attitudes based on doping experience were found to have publication bias, so we meta-analyzed two additional studies using a trim-and-fill algorithm and found a moderate effect size of -0.64 (95% CI = -1.23, -0.05), with a significant difference (p = .0343). Additionally, Korean athletes with doping experience had higher mean PEAS scores than those without doping experience.CONCLUSIONS This study suggests that attitudes may be important in predicting doping intentions or doping behavior.
News platformization in Portugal: analysis of the dependence of the news media on social media and search engines
Authors: Santos de Mattos Fabrício
Published: January 2024

The research aims to understand the news platformization process based on the identification and analysis of the dependence that Portuguese news media have on social media and search engines in the process of distributed discovery of news. The method replicated the dependency analysis model proposed by Nielsen & Fletcher (2002) and Tambini & Labo (2016), selecting the 30 Portuguese journalistic media with the highest average volume of web traffic between July, August, and September 2022. Thus, the different types of access were identified with the SimilarWeb platform, used in the literature as a reference source in webometrics. The data showed that 19 news media have more than 50% of indirect traffic dependent on the platforms. As for the total volume, we found that, on average, 56.26% of news access originates from social media or search engines; 36.05% from direct access; 7.05% from reference links; and 0.31% from email, sponsored search, and advertising. Considering mobile devices, the average dependency increases to 57.35% and, on desktop devices, it drops to 50.05%. We found that there is variation according to the type of media and its content: those specializing in football have greater direct access, and those specializing in lifestyle and celebrities have greater indirect access. Digital native media also rely more on platforms, as do media coming from Radio and TV. We conclude that platformization is a relevant phenomenon in the news ecosystem in Portugal, with significant integration of journalistic media content in these digital infrastructures. Thus, media will have to find ways to counterbalance the power of platforms, which, at the same time, improve connection with the user and increase audience reach, control data, interaction patterns, as well as online advertising, operating in a logic of increased dependency.

Published: January 2024

Tithonia diversifolia se ha difundido en los sistemas de producción animal en América Latina, pero las investigaciones muestran que existe gran variabilidad genética entre los materiales silvestres recolectados. El objetivo de este trabajo fue caracterizar morfológica y productivamente materiales de T. diversifolia recolectados en el noreste del estado Chiapas (México). Las recolectas incluyeron semillas y esquejes. Con las semillas se realizó un bioensayo de germinación y con los esquejes un experimento en campo con evaluaciones a los 90, 120 y 150 días de crecimiento. En ambos casos se utilizó un diseño completamente aleatorizado con tres y 13 repeticiones, respectivamente. Se recolectaron 34 materiales y se georreferenciaron las localidades de su procedencia. Doce presentaron semillas al momento de la recolecta. Todas las semillas mostraron capacidad germinativa. El mayor porcentaje de germinación (32.7 %) lo alcanzó el material # 32 mientras que el # 33 mostró el menor valor (0.7 %). El 50 % de los materiales recolectados tuvieron un índice de velocidad de emergencia (IVE) superior a 0.5, pero cinco no se reprodujeron en campo. Los materiales # 24 y 29 alcanzaron mayor altura y número de hojas por planta. El grupo con mayor producción de materia verde por planta (10.29 kg) estuvo conformado por los materiales # 14 y # 24. Las variables morfológicas y productivas posibilitaron conformar tres grupos de materiales vegetales los cuales se pueden introducir en diferentes alternativas para la producción animal en el estado de Chiapas (México).
Quando as Redes Sociais Digitais São Fontes Jornalísticas — Uma Abordagem a Códigos Deontológicos
Authors: Martins Paulo
Published: January 2024

A influência dos média sociais no campo do jornalismo, hoje incontornável, manifesta-se em várias vertentes, criando desafios que não podem ser ignorados pelos profissionais. Enquanto fontes, estão a ser cada vez mais utilizados, contribuindo para a emergência de novas dinâmicas de produção noticiosa, em particular na cobertura de acontecimentos em continuidade, nos quais impera a velocidade de transmissão e o imediatismo constitui um valor em si mesmo, incentivando a extração de conteúdos disponíveis na internet, sem tempo para escrutínio. Neste artigo, o fenómeno é enquadrado numa perspetiva ética. Através da análise de 32 códigos deontológicos — e instrumentos semelhantes — que incorporam esta realidade em partes específicas foram identificados valores e princípios jornalísticos neles inscritos acerca das modalidades de recolha de informação, sobretudo em redes sociais digitais. A exigência de verificação e validação do material e de identificação da fonte, procedimentos tradicionais, é predominante, atentos os potenciais riscos para o rigor de uma narrativa jornalística. Também é detetada, na maioria dos códigos integrados no corpus, a preocupação de acautelar o dano na esfera privada de cidadãos, eventualmente decorrente da difusão de material. Não se trata apenas de proteger a privacidade, em geral, mas de ponderar questões de grande sensibilidade a ela associáveis: a vulnerabilidade e dor em que se possam encontrar os autores das postagens e a presença nas redes de vítimas ou cidadãos menores de idade.

The purpose of this study was to explore, using topic modeling, the social value of doctors and medicine demanded by society as reflected in published newspaper articles in Korea. Ultimately, this study aimed to reflect social needs in the process of developing the Patient-Centered Doctor’s Competency Framework in Korea. For this purpose, a total of 2,068 newspaper articles published from 2016 to 2020 were analyzed. Through topic modeling of these newspaper articles over the past 5 years, 18 topics were derived and divided into four categories. Focusing on the derived topics and keywords, the topics derived in specific years and the proportion of topics by year were analyzed. The results of this study make it possible to grasp the needs of society projected through the press for doctors and medicine. Due to the nature of the press, topics that frequently appeared in newspaper articles were mainly social phenomena related to requirements for doctors, particularly dealing with economic and legal aspects. In particular, it was confirmed that doctors are now required to have a wider range of competencies that go beyond their required medical knowledge and clinical skills. This study helped to establish doctors’ competencies by analyzing social needs for doctors through the latest research methods, and the findings could help to establish and improve doctors’ competencies through ongoing research in the future.
Experimental analysis of factors affecting mobile phone use while driving
Authors: Márquez Días Luis Gabriel
Published: January 2024

While this is common behavior, has been found that mobile phone use while driving increases the risk of traffic accidents due to a decrease in driver reaction. To study the factors that define this behavior is important to refine policies to limit this. Using data from stated preference surveys implemented in Tunja (Colombia) was estimated a random coefficient model that explains why drivers use mobile phones while driving, using variables such as gender, old driving license, the speed reduction , importance of the phone call, travel alone or with, velocity and traffic ticket. In this context it was found that the most important variable is the traffic ticket with an elasticity of -1.236.

LeGESD: A framework oriented to the specification and formal validation of concurrent and distributed systems based on a graphical language and its process algebra semantics
Authors: Cortés Galicia Jorge , Menchaca García Felipe M. , Menchaca Méndez Rolando
Published: January 2024

The specification and formal verification of distributed systems is usually a complex task. It requires extensive knowledge of algorithm theory and modeling of distributed or concurrent systems. In this context, we present LeGESD which is a framework oriented to support the specification and formal validation of concurrent and distributed systems. LeGESD has a graphical formal language for the specification and analysis of distributed systems which is used to describe functional and of communication requirements. The semantics of LeGESD is based on the process algebra. This semantics is also described in this paper and it is called Analysis and Design of Distributed Systems (ADSD). ADSD is an algebraic specification with operational semantics defined to be used with LeGESD. ADSD provides graphical-algebraic equivalence relations which can be used to generate formal specifications of distributed systems. Lastly, this paper presents an example which shows the usefulness and potential of the language and its semantics.
Distributed maximum power point tracking in photovoltaic applications: active bypass DC/DC converter
Authors: Ramos-Paja Carlos Andrés , Giral Roberto , Arango-Zuluaga Eliana Isabel
Published: January 2024

An active bypass structure is proposed to maximize the power production in photovoltaic modules under mismatched conditions. Its efficiency is compared with single and distributed maximum power point tracking solutions based on conventional DC/DC structures. The analysis and simulations performed under realistic assumptions demonstrate the benefts of the novel active bypass converter over solutions based on Boost, Buck or Buck-Boost converters.
Voltage space vector‘s computation for current control in three phase converters
Authors: Berzoy Alberto , Viola Julio , Restrepo José
Published: January 2024

This work presents two current loop techniques, for three phase voltage source converters (VSC) used as controlled rectifiers (CR) operating at unity power factor. The first one is based on choosing the best natural vector, among the natural space vectors produced by two level voltage source inverters, with the use of a cost function. The second one is based on computing and synthesizing a space vector such that an absolute minimum in the cost function is obtained. The first algorithm is a simple method that presents power factor correction and good total harmonic distortion compensation. The second algorithm provides a novel and closed form formula to calculate the optimum voltage vector applied by the converter. In this method, pulse width modulation (PWM) is required to modulate the voltage vector that controls directly the line current, to follow the current reference. The simulations and experimental results show the advantages of the proposed control algorithm.
thermal electrical overheating. A physicochemical perspective of the electrical warming
Authors: Cárdenas Estrada Dorimdo Elam , Gracia Villar Santos , Fernández Diez Federico , Dzul Luis Alonso
Published: January 2024

The present article exposes the actual behaviors observed after  five years of investigation, experimentation and modeling, with electrical conductors that had a fault by high thermal conduction, with the principal purpose of producing a contribution that could be added to the existing regulations for the selection of wiring of electrical projects in low voltage. Till now, the experiments realized with electrical in amed conductors, in most cases are focused to trying to determine if the electric conductor was ignited by electric arch or if it was a victim of the fire, by means of physicochemical tests with the remains of the conductor. When we consider factors like the intensity of current, type of installation, environmental temperature, heat sources nearby conductors, conditions of overload, and the transverse effective section of conduction after consider skin effect and turns of cable, the selection of a suitable conductor becomes a difficult decision. All these factors are considered separately in Spanish norms as in international norms; despising in many cases some conditions that may be important cause of fault. Presented model is result of experimentation and a global analysis that takes care of all these factors simultaneously, after the review of conclusions of the most relevant chemical and physical investigations.
Using fracture energy to characterize the hot mix asphalt cracking resistance based on the directtensile test
Authors: Walubita Lubinda F. , Alvarez Allex E. , Sanchez Flor
Published: January 2024

Cracking is currently one of the most common distresses in hot mix asphalt (HMA) pavements, often costing the highway agencies million of dollars in maintenance and rehabilitation activities. Laboratory characterization of HMA cracking resistance thus constitutes a fundamental step in mix-design and analysis to ensure adequate Æ eld performance in terms of this distress. This study assesses the suitability of analyzing the HMA cracking resistance using fracture parameters determined based on the direct tension test, which include the fracture energy. Corresponding results suggest that the fracture energy and the proposed fracture energy indices has promising potential to be used as fracture parameters to discriminate the cracking resistance potential of HMA mixes in the laboratory. More research is recommended to further reÆ ning this concept and relate to Æ eld cracking resistance data.
System of heart and lung sounds separation for store-and-forward telemedicine applications
Authors: Salazar Antonio José , Alvarado Catalina , Lozano Fernando Enrique
Published: January 2024

Auscultation is a medical procedure that provides a general idea of heart and lung behavior as the physician listens to the breath sound. Due to the fact that the sounds from these organs overlap in time and frequency domains, important affections in one of them could be discarded. For instance, the objective of this work is to implement two different methods of cardiac and pulmonary sound separation. First, we apply modulation filters to the timefrequency representation of the original signal, recorded on the chest. Second, we apply an iterative algorithm of wavelet decomposition and reconstruction filters. Results show that they both separate signals appropriately. Taking lung signals as noise, we determine that signal to noise (SNR) ratio is 10.21 for the first method and for 6.61 the second. Applications in telemedicine are encourager since the bandwidth of the signal transmission could be reduced by sending it separately.

Published: January 2024

This work presents a comparison between four control techniques applied to drive a PMSM: Classic DTC, Modified DTC with a Fuzzy Inference System, Predictive DTC and Predictive DTC with Fuzzy Inference System. Parameters estimation for the predictive strategies is performed using a population-based search algorithm (Bacterial Foraging), which is able to calculate on line the PMSM parameters. The electric torque and stator flux linkages experimental results show that the predictive strategies that use the machine parameters estimated by the Bacterial Foraging Algorithm present a significant improvement when compared with non predictive techniques.
