Authors: Arigi Julio Pasha , Hidayat Z. , Putra Devi Olivia , Gulo Agus
Published: December 2024

This in-depth study explores the evolving metrosexual consumer lifestyle within Indonesia's urban centers and specifically delves into how the metrosexual community utilizes Instagram as a platform for self-representation and social interaction. Employing a qualitative, phenomenological approach anchored in constructivism, data were gathered through a multifaceted approach, including in-depth interviews with key informants, participant observation through examination of Instagram profiles and online interactions, as well as a comprehensive literature review to contextualize findings. To identify study participants, strategic keywords such as "metrosexual," "lifestyle," and "men's beauty" were applied on Instagram search. The selection was meticulously narrowed down to ten highly active endorsers and followers with the most significant engagement. The approach ensured that rich insights from individuals deeply embedded within the metrosexual community on Instagram were captured. The study unveils intriguing aspects of Indonesian urban metrosexuals' consumption habits and social media preferences. Their primary concern lies in the effectiveness of beauty products in enhancing their appearance, prioritizing results over mere brand prestige. The focus on practicality is further reflected in their preferred places to meet. Shopping malls emerge as their preferred destinations for social activities. When it comes to social media, Instagram is the most popular choice. Its visual focus and content sharing align perfectly with the metrosexual community's interest in self-presentation and cultivating a meticulously crafted online image. The research also highlights the significant role of physical appearance in boosting self-esteem within the metrosexual community, influencing their interactions both online and offline. The managerial implications of this study indicate the importance of paying attention to male consumers for beauty products and services.

Ex-prisoners are defined as those under the Internal Security Act who have previously committed offenses connected to the incidences of disturbance/conflicts in Thailand's southern border provinces. Additionally, certain people have a strong propensity for repeat transgressions, which could be detrimental to society. This study used qualitative research techniques and in-depth interviews to examine psychological circumstances, social coexistence, means of subsistence, occupations, and current support practices. Following a period of reintegration into society, some observations were made namely: i) 23 ex-prisoners in the southern border provinces were on insurgent charges, ii) 10 government employees with five years of experience were in care, assistance, healing, and rehabilitation process, and iii) four members of civil society with five years of experience in aid, recovery, and rehabilitation were among the informers for the sources of information. The results also revealed that most ex-prisoners experienced psychological stress and anxiety after re-entering society. This phenomenon occurs due to issues related to debt, low income, localized violence, and frequent visits by the army troops' to their houses, it was discovered that some groups were stigmatized by local residents. Nevertheless, they were found to have adjusted to living and got along well with their families. In terms of occupation and sources of income, it was found that most were merchants, general laborers, and rubber tappers. Additionally, the community networks supporting the restoration of coexistence in the community are either the responsibility from government agencies or authority both direct or indirect involvement of the civil society organizations/Non-Governmental Organisation (NGOs). The findings of this study will be helpful in establishing a framework for assisting and rehabilitating the quality of life of ex-prisoners under the Internal Security Act that is congruent with the local requirements and context.

Reactive oxygen species (ROS) play a role in multiple physiological processes. In contrast, an excessive generation of ROS can harm various biological components, including proteins, lipids, and DNA, leading to accelerated aging, illness, and inflammatory disorders. Carbon-based nanomaterials (CNMs) are well-known nanomaterials widely developed for antioxidant activity because of their great biocompatibility, low toxicity, easy synthesis, unique physicochemical properties, and especially great ROS scavenging ability. The most general method to prepare CNMs is bottom-up synthesis because it is more environmentally friendly and economical than top-down methods. In this study, the antioxidant activity of CNMs was evaluated. A microwave-assisted pyrolysis method was applied at 200°C for 20 min to prepare gallic acid carbon-based nanomaterials (GACNMs) by using 2.5 mg/mL of gallic acid as a carbon source according to the previous research. The morphology, cytotoxicity on normal human fibroblast cell lines by 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2H-tetrazolium bromide assay, and antioxidant activity using a 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay were elucidated. The results revealed that the GACNMs were spherical, with a particle size of 104.43±0.43 nm, and their structure was in line with the previous study. The GACNMs exhibited higher antioxidant activity (50% scavenging capacity (SC50) of 0.99±0.07 μg/mL) than the gallic acid solution (SC50 of 1.25±0.03 μg/mL). The GACNMs were non-toxic to fibroblast cells. Therefore, the GACNMs could be a promising nanomaterial for skin antioxidants.

It is well known that the epic "Manas", due to its multi-layered encyclopedic content, occupies a special place among the national spiritual heritage. Among the issues of greatest interest in the epic, biological concepts and the views of the Kyrgyz people are of great importance. After all, there are many biological concepts, names and images in the structure of the epic, including archaic mythical and fabulous biological concepts belonging to the most ancient epochs. One of the mythical and fairy-tale concepts among them is Itaals. Biological creatures with the head of a dog and the body of a human are found not only in the epic “Manas”, they are found in folklore, legends, myths, fairy tales of different peoples of the world: Indians, Egyptians, Slavs, Siberian peoples, Mongols, etc. The correspondence of the descriptions of Itala in the epic "Manas" to the images of humanoid creatures with a dog's head depicted in them can be considered in connection with the commonality in the worldview of ancient people.
La Democracia argentina y las visiones teleológicas de la historia conceptual
Authors: Palti Elías José
Published: December 2024

El difundido y profundo rechazo a la Democracia a lo largo del siglo xix y buena parte del siglo xx es uno de los tópicos al mismo tiempo más preocupantes y menos abordados por los estudiosos de la historia política latinoamericana. Aunque perturbador, su sentido y origen no parecen plantear ningún interrogante digno de consideración detenida: el mismo trasuntaría, de forma muy evidente, arraigados prejuicios entre la élite local, que tendrían raíces sociales, culturales o históricas más generales. Esta perspectiva, fundada en una visión normativa y teleológica de la historia, ha obturado toda indagación subsiguiente. El hecho de que los actores del periodo se hubieran problematizado conceptos como el de Democracia sólo podría atribuirse a un lamentable error, una falta de comprensión de aquel verdadero concepto suyo que el historiador en cuestión afirma conocer. En fin, la historia político-intelectual del siglo xix no sería más que la de una larga y lamentable sucesión de malentendidos. En definitiva, si queremos hallar un sentido sustantivo a estos debates, resulta imprescindible antes desmontar las premisas de cuño teleológico desde la cual fueron hasta ahora leídos. Y es aquí que el recurso a la historia conceptual se vuelve ineludible. Como este texto se propone demostrar, sólo un trabajo sobre los conceptos permite calibrar la naturaleza profundamente dilemática del tipo de cuestiones a las que sus actores se enfrentaban. Y, de este modo, rescatar también el caso latinoamericano del lugar de una mera anomalía local, sin relevancia ninguna para la historia político-conceptual occidental.

Published: December 2024

El presente trabajo pretende rastrear la movilidad del concepto Democracia en el Perú entre 1790 y 1870. Esta movilidad es entendida desde el punto de vista de la ampliación semántica del término a lo largo del periodo estudiado, se trata de entender los escenarios contextuales del Perú en este periodo vinculándolo con los significados que va adquiriendo Democracia. Al mismo tiempo que relaciona la voz Democracia con los distintos temas que la misma incluye: soberanía popular, sufragio popular, igualdad, libertad, educación, entre otros. Se pretende con este artículo cubrir un periodo importante de transformaciones políticas con uno de los conceptos que contiene una polisemia importante, al aumentar sus significados podemos demostrar ciertas modificaciones al término pero de la misma manera ciertas continuidades que deben ser valoradas, un concepto que se transforma constantemente pero que a la vez mantiene ciertas posturas ancladas en el pasado dependiendo de los actores que la defiendan, esto nos permite acercarnos a la realidad política y social del Perú en las décadas señaladas.
Del Despotismo de la gentuza a la Democracia de corbata lavada
Authors: Cyril Lynch Christian Edward
Published: December 2024

El presente artículo intenta ofrecer una historia del concepto de Democracia en Brasil entre 1770 y 1870, periodo en el cual prevaleció una fuerte tensión entre los conceptos de Gobierno representativo y de Democracia. Los conservadores interpretaban la Monarquía constitucional como un Gobierno mixto, rechazando la Democracia como algo incompatible con el carácter singular de la población brasileña, esclavista, analfabeta e irregularmente distribuida por el territorio nacional. Aunque críticos con los conservadores, a lo que atacaron como aristócratas, los liberales mantenían una relación muy ambigua con la Democracia, en la medida en que ellos recelaban de las pretensiones igualitarias de las clases bajas, incluida la esclava. Por eso, ellos preferían conciliarse con la Monarquía constitucional representativa, postergando sus ideales republicanos o democráticos para un futuro distante. Ese hecho no les impedía defender una interpretación más «democrática», o sea, parlamentaria y Federal, de la Monarquía.

La transición al liberalismo en España a comienzo de la década de 1830 obligó a las elites tradicionales a llevar a cabo un complejo proceso de adaptación. Algunos de sus miembros lograron incrementar su influencia y, el caso que analizamos, es un buen ejemplo de ello. Mariano Miguel de Reynoso, miembro de una familia de hidalgos que utilizó su prestigio social y una indudable habilidad política para convertirse en el representante de los poderes económicos castellanos ante el parlamento nacional durante las décadas de 1840 y 1850.
Opinión popular y actitudes sociales en los regímenes totalitarios y fascistas de la Europa de Entreguerras, 1919-1945. Un recorrido historiográfico
Authors: Cobo Romero Francisco
Published: December 2024

A lo largo de las tres últimas décadas, las escurridizas y dificultosas cuestiones relacionadas con las distintas maneras con que los ciudadanos resistieron o asumieron la dominación de las dictaduras totalitarias o fascistas de la Europa de entreguerras se han unido al interés por las formas que revistieron sus opiniones, actitudes y comportamientos frente a esas mismas dictaduras. En consecuencia, el estudio de la opinión popular de la población, sujeta a su dominio, resulta imprescindible para comprender mejor de qué manera, y sobre todo con qué grado de eficacia, lograron concitar el apoyo mayoritario de la población alrededor de sus propuestas políticas, o bajo qué pretextos consiguieron neutralizar o abortar las expresiones de la disidencia o descontento. Analizaremos, pues, las oscilaciones experimentadas por la historiografía ocupada del análisis de la opinión popular y las actitudes políticas de la sociedad en los regímenes totalitarios y fascistas de la Europa de entreguerras a lo largo de las últimas décadas. Señalaremos, asimismo, el movimiento pendular registrado en sus percepciones.
¿Qué es una nación? Krausismo, y nacionalismo español en 1882
Authors: Archilés i Cardona Ferran
Published: December 2024

Fernando Gasset Lacasaña es un republicano español olvidado, autor de una obra igualmente olvidada sobre la idea de nación publicada en 1883. Su trabajo, desarrollado bajo la influencia del krausismo español es una interesante reflexión sobre la manera como estos autores definieron su idea de nación española. Este artículo trata de ofrecer una nueva perspectiva sobre esta rama del pensamiento nacionalista español, usando a Gasset como estudio de caso. Lejos de ser un ejemplo de nación cívica, la idea defendida por los krausistas españoles fue la de una definición etnocultural. Además, se plantea una nueva visión del lugar más bien limitado que la región y el regionalismo podían tener en el marco de una propuesta política nacionalista española.
Introducción. Estado y nación en la Europa del sur en la época liberal
Authors: Suárez Cortina Manuel
Published: December 2024

Los países de la Europa del Sur conforman un espacio geopolítico muy adecuado para la historia comparada de la construcción del Estado y la nación. Con procesos de unificación política y de nacionalización distintos, sin embargo, Italia, España y Portugal comparten en la época liberal múltiples elementos económicos, sociales y políticos: desarticulación territorial, atraso económico, emigración e inmigración, analfabetismo, centralismo político, cultura católica, clientelismo político. Todo ello facilita la comprensión de los ingredientes propios de cada Estado-nación, así como de aquellos otros que, por encima de su dimensión nacional, encuentran una explicación más completa desde la observación de la Europa del sur como una unidad supranacional.
Las Casas del Pueblo socialistas en Castilla y León
Authors: De Luis Martín Francisco , Sarmiento García Tomás
Published: December 2024

Las Casas del Pueblo fueron los espacios de sociabilidad socialista más importantes. Y no sólo desde el punto de vista político y sindical, sino cultural también. Entre sus muros tuvieron cabida todo tipo de actividades societarias, cooperativistas y de ocio, que conformaron, en buena medida, la mentalidad obrera y popular del primer tercio del siglo XX español. Estos centros tuvieron en Castilla y León una presencia muy significativa aunque desigual en función de la diferente potencia socialista en las distintas zonas —urbanas y rurales— y el desarrollo económico de las mismas. Y aunque sus características básicas —funciones, servicios, rituales y liturgias, actividades...— no se diferencian de las del resto de España, en su implantación y desarrollo presentan una gran heterogeneidad y no pocas peculiaridades. Este trabajo pretende acercarse al rico muestrario de Casas del Pueblo que se erigieron en nuestra comunidad, analizando de forma pormenorizada algunas de las más significativas.

Published: December 2024

Este artículo tiene como objetivo presentar los resultados de la incidencia en el rendimiento académico de la componente aleatoria después de implementar una secuencia didáctica basada en los estilos de aprendizaje de cada uno de los estudiantes de grado octavo. Este estudio se originó al observar los bajos resultados académicos obtenidos en matemáticas por los estudiantes de una institución en las pruebas nacionales.
Se usó una metodología cuantitativa para analizar los datos obtenidos de 131 estudiantes de grado octavo a partir de tres instrumentos: un cuestionario para identificar los estilos de aprendizaje y dos pruebas estandarizadas (pre-test y post-test). Con estos instrumentos se realizaron los análisis correspondientes a los estilos de aprendizaje y el rendimiento académico de los estudiantes.
En el primer instrumento se encontró que algunos estudiantes tienen uno, dos o tres estilos de aprendizaje simultáneamente. Con el pre-test se demostró que los estudiantes tuvieron un rendimiento académico básico en las competencias de la componente aleatoria. Teniendo en cuenta estos resultados, se diseñó e implementó una secuencia didáctica basada en los estilos de aprendizaje identificados en cada uno de los estudiantes de un grupo experimental.
Para finalizar, se implementó el post-test y de los resultados obtenidos se comparó el rendimiento académico de los estudiantes de los grupos experimental y control. Los resultados mostraron que los estudiantes del grupo experimental pasaron del rendimiento académico básico al alto. De lo anterior se concluye que, la secuencia didáctica contribuyó a mejorar las competencias matemáticas propuestas en los estándares curriculares del MEN.

ECG measurements at rest are susceptible to different kinds of noise which may affect clinical interpretation. Unlike the low-frequency body movements or spectrally well-defined power line interference, the broadband electromyographic (EMG) noise spectrally coincides with the QRS complex, which makes its removal particularly challenging. While a number of algorithms have been developed, their evaluation and comparison have long remained challenging due to the lack of a database with EMG-contaminated and genuine noise-free signals. We have recently published a SimEMG database of the simultaneously recorded EMG-noise-free and -contaminated ECG signals. In this paper, we examine the capability of SimEMG to become a reference test set for different denoising algorithms. We show that the SimEMG is useful for the assessment of the signal morphology distortions leading to potentially misleading changes in the diagnostic markers. We examine the ST segment – a marker of acute myocardial infarction, and R, Pmax, and Tmax points– the markers of arrhythmias. The tests are performed with the adaptive wavelet Wiener filter, wavelet transform (WT), finite impulse response (FIR) filter, and iterative regenerative method (IRM). The analysis also reveals the residual noise as a minor limitation of the database and acquisition method. Possible improvements are discussed.

The prevalence of high order harmonics in power systems results in demand for measurement equipment calibration in non-sinusoidal conditions. Establishing a routine examination procedure is challenging, when reactive power/energy instruments are regarded, for two main reasons: their role in the billing of electrical energy and the fact that the term reactive power/energy is not unambiguously defined in case of harmonically distorted signals. Additionally, the existence of multiple measurement algorithms, implemented in different measuring units, results into further complication of the concrete task. These algorithms provide the same result in case of sinusoidal voltages and currents, while in case of harmonics, the instruments’ performance may vary significantly, when different power theories are adopted. In the paper, measurements conducted with a reference standard of highest accuracy class available are presented and the obtained measurement errors are further discussed. The obtained results are analyzed regarding the theoretical remarks, derived from the analytical expressions of both the standard’s measuring algorithm principle and the different definitions for reactive power/ energy in non-sinusoidal conditions.

This paper explores the application of complementary and Kalman filters in signal filtering obtained from accelerometers and gyroscopes. Accelerometers and gyroscopes are commonly used sensors in various applications such as navigation, aircraft stabilization, robotics, and sports. However, signals obtained from these sensors are often susceptible to noise, vibrations, and other effects that can affect measurement accuracy and result in unreliable data. The complementary filter combines data from both sensors in a way that minimizes errors and provides a stable estimation of the object's orientation in space. On the other hand, the Kalman filter uses mathematical system models and statistical methods to optimize the state estimation of the system based on measurements from both types of sensors.

Bulk samples of Pbx(As2S3)100-x chalcogenide glassy system obtained by melt quenching method were subjected to the measurement of their electric and dielectric properties over the temperature and frequency ranges (323-423 K) and (0.1 Hz-100 kHz) respectively. The introduction of lead into the system significantly increases DC and AC conductivity. Hoping between the localized states was identifed as a dominant conductivity mechanism in DC regime. The results of ac conductivity measurements are explained based on the correlated barrier hopping CBH model. The AC impedance analysis by means of an equivalent circuit model was used to found correlation between the distinct microstructures and electrical properties of these compounds. The high insulating nature of investigated samples in the whole frequency range was established. The frequency dependence of dielectric losses at different temperatures was also analyzed.

Nuclear power plants represent critical infrastructure assets essential for global energy production, embodying both immense potential for state and significant risks. This paper examines the possibility of insider threats within nuclear power plants, clarifying the complex interplay among human factors, security measures, and technical vulnerabilities. By synthesizing existing literature, this study explains the multifaceted nature of insider threats, encompassing malicious actions by employees, contractors, or other trusted entities operating within the facility. The analysis delves into various dimensions of insider threats, primarily focusing on the motivation, capabilities, and intentions of insiders to attempt unauthorized removal or sabotage of nuclear or other radioactive material. This study also examines the main attributes of insider threats, i.e., access, authority, and knowledge. Drawing upon insights from security and radiation protection disciplines, this paper explores the behavioral and organizational factors that contribute to insider risk, emphasizing the importance of understanding human dynamics in safeguarding nuclear facilities. Furthermore, this study assesses the efficacy of existing security measures in mitigating insider threats and identifies areas for improvement. In this paper, we examine strategies ranging from access controls and background checks to personnel screening and psychological profiling, evaluating their strengths, limitations, and ethical considerations. This also includes analyses of pathways through which insiders may exploit vulnerabilities to compromise plant security. Through a comprehensive examination of insider threat scenarios and countermeasures, this paper underscores the imperative for a multidisciplinary approach to nuclear plant security, integrating technical, procedural, and human-centered elements. It advocates for enhanced training and awareness programs to cultivate a culture of vigilance among plant personnel and stakeholders, emphasizing the shared responsibility of safeguarding nuclear facilities against insider threats. Central to this approach is the promotion of a robust nuclear security culture, fostering a mindset of continuous improvement and adherence to best practices in security protocols and risk mitigation strategies.

In this paper, particular study of security of ground-to-unmanned aerial vehicle (UAV) communication link, on physical layer, in the presence of a ground eavesdropper is given. We characterize the UAV as data collector, which is distributed randomly in a horizontal plane of certain cylindrical region, while a ground user that sends data up to UAV, is located in the centre of cylinder's base. Furthermore, we assume that the eavesdropper is randomly located within a circle which defines the base of the cylindrical region. The main (user-to-UAV) channel is characterized as severely corrupted by the path loss effect, while the wiretap (source-to-eavesdropper) channel is subjected to Fisher-Snedecor fading. Under aforementioned system/channel scenario, the probability of intercept events is investigated. In more details, throughout numerical results, the impact of the predefined cylinder's height and its base's radius, as well as the impact of the fading depth and shadowing severity of the ground wiretap channel, on the intercept probability, is analysed. Related concluding remarks are also given.

This paper presents the implementation and evaluation of the YOLOv8 detection method within the domain of ground-penetrating radar (GPR) imagery analysis. YOLOv8, an evolution of previous YOLO models, is employed for object detection tasks, providing efficient and accurate results. The study focuses on detecting and classifying three distinct objects: corner reflector, anti-tank (AT) mine, and glass bottle. Training data preparation involves annotating radar images and splitting them into training, validation and testing sets. The YOLOv8 model is trained on labeled data, and its performance is evaluated based on precision, recall, and F1-score metrics. Results demonstrate high accuracy in detecting and classifying objects, with minimal false positives. Further testing in real-world scenarios is suggested to assess model robustness under varied environmental conditions and object densities.
