Moda autóctona: una mirada despatriarcalizadora
Authors: Vidal Josefina
Published: December 2023

La denominada moda autóctona es una corriente en la moda chilena que se desarrolló entre 1968 y 1973, con la cual se identifica el trabajo de cinco creadores de vestuario y estampados textiles: Nelly Alarcón, Enrique Concha, Marco Correa, María Inés Solimano y Alejandro Stuven. Dicha corriente del diseño ha sido reconocida como un movimiento que intentó oponerse a las referencias europeas, rescatando «lo propio» del  país y de Latinoamérica. Establecemos una mirada crítica de este fenómeno desde la teoría feminista, particularmente desde los postulados de Donna Haraway, Ochy Curiel, María Galindo y Rossi Braidotti. Analizamos entonces 21 el trabajo de Enrique Concha, quien organizó en 1972 la muestra «Un Chile  oculto: campaña de la moda y vestuario autóctonos chilenos» en el Museo Nacional de Bellas Artes, donde expuso sus estampados «inspirados» en la cultura diaguita y rapanui. Esta revisión crítica argumenta cómo esa exposición es una apropiación cultural dirigida por Enrique Concha, la cual se ha considerado hasta hoy como un ejercicio positivo, justificándola como una emancipación de la metrópolis.

En esta comunicación describiremos de qué manera los avances realizados en el marco del proyecto de investigación «Mujeres hacedoras: hacia una historia feminista del Diseño del siglo XX» permitieron enunciar nuevos interrogantes respecto de su objeto de estudio, esto fue posible a partir de la realización de tres seminarios internos de lectura, organizados por el equipo de investigación, a fin de discutir las categorías conceptuales centrales del proyecto. La metodología implementada durante los  mismos fue de tipo cualitativa, siendo la revisión documental la principal técnica motorizada. En estos espacios se evidenció que la categoría de invisibilización patriarcal desconocía discusiones ya superadas en los debates articulados entre la crítica historiográfica y los estudios de género, empobreciendo la potencialidad de la casuística como estrategia en el relevamiento de material empírico. Frente a ello decidimos modificar el objetivo general de la investigación para analizar el discurso historiográfico hegemónico sobre el diseño en el siglo XX, atendiendo a las formas  de inclusión disciplinar de las mujeres en tanto que objeto y sujeto de diseño, e historizar la producción de mujeres diseñadoras, reparando 49 en las vinculaciones que establecen con los significados y sistemas de jerarquización patriarcal al interior del propio campo disciplinar.

ANALISIS PANDU GELOMBANG MENGGUNAKAN BRAGG RELECTOR SEBAGAI CLADDING
Authors: Wenas Donny R.
Published: December 2023

This study aims to examine the mode that can pass through the waveguide and calculate the filling factor and efficiency of the Bragg Reflector.

For that purpose in this research, a program using Matlab has been created to analyze the propagation data of the waves in the material, cylindrical waveguides, and Bragg reflectors. From the results of this study, it has been found that a cylindrical perforated waveguide with a Bragg Reflector as a cladding, is one way to overcome the chromic dispersion of optical fiber materials. This is because the electromagnetic waves traveling through the air (n=1) do not experience dispersion. The replacement of the core material with air requires a sheath that acts as a reflector at a certain wavelength, this sheath is known as a Bragg Reflector. The calculation of the band structure of the Bragg Reflector shows the presence of a bandgap in the coordinates. This pair in the bandgap area experiences the reflection required for the waveguide. From the continuity requirement, the forbidden bandgap shows the mode that can propagate in the optical fiber, the efficiency is calculated and the amplitude and power profile graphs are plotted. From the results of the calculations performed, it is found that each mode has an efficiency of more than 60% and increases for wider cores, both for single-mode and multi-mode.

Published: December 2023

Organic molecules with a conjugated chain structure such as the Disperse Red-1 (DR-1) molecule are known as potential materials for photonic device applications. The aim of this research is to study the surface effect of Indium Tin Oxide (ITO) substrate and the external electric field of 2.6 MV / m in regulating the orientation of the DR-1 film molecules on the surface of the ITO substrate. The fabrication method used is the PVD (Physical Vapor Deposition) method assisted by an external electric field. This method is a modification of the conventional PVD method which is equipped with the addition of an external electric field (E) in the chamber. The film was made on the surface of the ITO substrate with the deposition of DR-1 molecules in a variation of the external electric field, namely zero field and E = 3.3 MV / m. The films were analyzed and characterized using XRD (X-Ray Diffraction) spectroscopy. The X-ray diffraction measurement analysis showed that the DR-1 molecules were arranged in an orderly manner parallel to the surface of the ITO substrate, indicating an indication of the strong surface effect of the ITO substrate from the hydrogen bonding of the DR-1 molecule with the ITO substrate. The results of spectroscopic measurements show that with an increase in the external electric field, there is an increase in the effect of aggregation of molecules arranged in an orderly manner perpendicular to the surface of the ITO substrate.

Spread in several regions of Indonesian following the boundaries of the active plate starting from the islands of Sumatra, Java, Bali, West Nusa Tenggara, Flores, Sulawesi and Maluku. Soputan volcano is one of 127 active volcanoes in Indonesia, is a Strato volcano. As an active tecto-volcanic country, with many volcanoes we try to minimize and prevent the dangers posed by volcanic eruptions. Based on these thoughts, to date in Indonesian various methods of volcanic natural disasters have been carried out, including earthquakes (seismic). Volcanic earthquakes usually occur in the area around volcanoes and their magnitudes are generally very small, averaging less than 5 on the Richter Scale. The depth of the volcanic earthquake ranges from 0-40 km. Based on the hypocentrum distribution of the depth of the epicenter, it shows that the earthquake point that occurred before the eruption was at a depth of 0 km - 2 km at sea level, while the point of the earthquake that occurred during the eruption was at a depth of 0 km - 2 km below sea level, the point of the earthquake that occurred after the eruption it is at a depth of 0 km - 3 km below sea level. The mechanism for the eruption of Mount Soputan Volcano is a visual change in the vegetation around the crater, the plants turn yellow and can die, as soon as the thin crater turns gray.

The level of salinity in water quality is one of the determining factors in the success of seaweed aquaculture production. The purpose of this study was to develop a website-based monitoring system for the level of water salinity in seaweed ponds. Monitoring system development is carried out by designing and developing an integrated website. Measurement of water salinity in ponds uses a sensor with a microcontroller connected via the internet network so that monitoring can be carried out without the need to go to the pond location. This type of research is development (Research and Development) which refers to the waterfall model (Planning, Analysis, Design, Implementation, Maintenance). The results of the research show that website development as a monitoring system has been successfully developed. There are four pages that can be displayed on the website for monitoring seaweed pond water salinity, namely the login page, homepage, viewing data, and monitoring water salinity. This research is expected to provide an overview in monitoring water quality in increasing the productivity of seaweed cultivation.

Pine Forest is one of the tourist attractions in Lahendong Village, which has geothermal manifestations in the form of hot springs, which shows that the area has geothermal potential. The purpose of this study was to determine the type of fluid manifested by hot springs in the Pine Forest using geochemical methods. The results of this study indicate that the temperature at the manifestation is 40°C while the degree of acidity of the pH of hot water has a value of 4 which indicates the acidity level of hot water is acidic. The type of fluid that exists in the manifestation area of hot water in the Pine Forest is the type of fluid sulphate water and sulfate water is a fluid that is formed at shallow depths and is formed as a result of the condensation process of geothermal gas towards near the surface. This is because the results of chemical analysis show that the element SO4 is the most dominant element and contains SO4 gas. Hot water that has a sulfate type is water that is formed at shallow depths and is formed as a result of the process of condensing geothermal gas towards near the surface. The geothermal gas with gas content (water and carbon) is basically dissolved in the fluid content which is located in the deep zone but separated from the chloride water. Sulphate water is usually at the boundary and not far from the main upflow zone.

La emergencia sanitaria producto de la pandemia COVID-19 generó afectaciones en la salud mental de la población en general y en especial en el personal sanitario. Este estudio se basa en una encuesta realizada a personal sanitario en cinco países (Argentina, Brasil, Chile, Perú y Uruguay). La muestra fue de 9.820 participantes, con 79,6% de mujeres. Se construyeron modelos de regresión logística múltiple para hombres y mujeres en cada país, identificando los factores que estaban asociados al deterioro de su salud mental. Las mujeres reportaron un mayor deterioro de su salud mental y un perfil diferente de factores asociados a esto. Estos hallazgos se relacionan con los roles tradicionales según género, donde las mujeres tienen un mayor peso en el cuidado de los otros y valoran los aspectos relacionales por encima de los personales, a diferencia de los hombres quienes otorgan más importancia al ámbito público y al cuidado propio. Se resalta la importancia de incluir el enfoque de género en el diseño de políticas para el personal de salud, especialmente en el cuidado de su salud mental.
Osteopathic Manipulative Treatment to Treat Patients with Long-Haul COVID Loss of Smell and Taste: A Report of Four Cases
Authors: Berkowitz Murray R.
Published: December 2023

Four cases of patients with Long COVID symptoms of loss of the sense of smell and sense of taste are presented. They differ from the findings in the published case record of anosmia and loss of taste in Magoun. Osteopathic examination revealed flexion and extension of the occiput. No flexion or extension motion of the sphenoid was appreciated. A novel application of the underlying concepts of Osteopathic Cranial Manipulative Medicine is described. This approach resulted in a rapid resolution of the symptoms of loss of the senses of smell and taste, which have persisted for more than a year. An hypothesis for a possible mechanism of the pathophysiology is advanced. The olfactory nerve (CN I) lies on the cribriform plate of the ethmoid bone. When the inflamed sphenoid flexes, becoming stuck down forward on the cribriform plate of an inflamed ethmoid. This may have resulted in impingement of CN I, which then resulted further in anosmia (loss of smell) and concomitant loss of taste.
An Osteopathic Approach to Vertigo with Galbreath Technique: A Case Report
Authors: Hurrle Samantha , Matz Olivia , Vo Carolyn , Lewis Drew D.
Published: December 2023

Vertigo is a symptom with a wide range of etiologies as diverse as the patients it affects. The wide spectrum of etiologies can make a diagnosis difficult and therefore delay definitive treatment. The diagnosis is not commonly linked to somatic dysfunctions, however these somatic dysfunctions may be contributing to or causing a problem altogether. This case highlights the importance of investigating for somatic dysfunctions related to a patient’s presentation. A 73-year-old female presented with a history of vertigo and a current feeling of fullness and ringing in her ears. She was found to have significant Eustachian tube dysfunction related to her condition. An osteopathic approach with emphasis on the Galbreath technique was utilized to relieve her ear symptoms and decrease her ongoing episodes of vertigo.
Historiosophical reflections by Leonid Borodin in his autobiographical narrative “Without a choice”
Authors: Darenskiy V. Yu.
Published: December 2023

The article examines Leonid Borodin’s historiosophical ideas stated in his autobiographical narrative “Without a choice”. It is shown that according to Leonid Borodin, the comprehension of the Russian history and the world history meaning was an existential effort rather than an abstract thought. Leonid Borodin’s historiosophical thought was hard won through his personal spiritual searches and coming to Orthodoxy. Therefore, it continued the tradition of the great Russian philosophers by becoming congenial to them and having risen up to their level. The spiritual logic of history, which requires spiritual and philosophical culture for its fundamental understanding, was discovered by Leonid Borodin thanks to the restoration of connection with the Russian philosophy of the Silver Age. The catastrophic lapse of a large portion of the people into the “satanic abyss” in the twentieth century can be explained precisely by the fact that it was basically caused by a religious deception and temptation rather than by a naive belief in the bright future. Namely, this is the obsession with pride, which does its best to “rebuild the world”. The internal spiritual and existential foundations of the philosophical understanding of the history by Leonid Borodin are also featured here. These are: 1) the thinking — free and seeking — and at the same time strict and heroic; 2) it is based on the highest spiritual comprehension of the truth, always associated with the mystical penetration into the flesh of history rather than on rational constructions of the mind (they are set up later as a result). Leonid Borodin had to resist this type of “dissidents” — Russophobes — even more fundamentally than the Soviet regime itself, since they became enemies of the Soviet regime not because of love for Russia, but, on the contrary, because of hatred for the country rather than for the regime. Leonid Borodin’s, just like Konstantin Leontiev’s, historical thinking was based not on some predefined schemes, but, first of all, on the aesthetic, full-blooded penetration into this meaning, “letting it pass through yourself”, experiencing it internally as a personal tragedy and personal fate, through which both the fate of the people in the twentieth century and the Christian meaning of the Russian history in general became clear.

Objetivo. Evaluar de manera integral el efecto de la salinidad en plantas de la variedad CW 660 de Medicago sativa L., sometidas a dos tratamientos: fertilización con nitrógeno e inoculación con una cepa halotolerante de Sinorhizobium meliloti. Materiales y métodos. Las plantas de M. sativa L. se dividieron en dos grupos: fertilizadas con nitrógeno, pero no inoculadas con S. meliloti (PF) e inoculadas con S. meliloti pero sin fertilización (PI). El estrés salino se indujo con solución de Hoagland y NaCl (50, 100 y 200 mM) para PF, misma solución con nitrógeno limitado para PI. Las variables repuestas evaluadas fueron longitud (L), peso fresco (PF) y peso seco (PS) de raíces y partes aéreas, pigmentos fotosintéticos (clorofilas a, b y carotenoides) y concentración de prolina tras cuatro semanas de tratamiento. Resultados. Mediante modelos aditivos generalizados (GAM, por sus siglas en inglés), se evaluó el efecto de salinidad e inoculación sobre las variables repuestas. Las PI mostraron mejoras significativas en la longitud aérea y radical, y en las clorofilas a y b bajo estrés salino, en comparación con PF. La concentración de prolina bajó en PI. La nodulación disminuyó debido al estrés salino, pero la inoculación promovió nódulos activos. Conclusión. La inoculación con S. meliloti halotolerante mejoró la resistencia al estrés salino, impulsando el crecimiento de las plantas.
